Suitable Network To Implement In Gaming Centre Computer Science Essay In this documentation, is going to propose a suitable network to implement in gaming centre. In order to select the right network, it is necessary to have understanding and knowledge on various types of network, to know the efficiency and reliability of the network, various types of game and requirement, network topology and architecture, ISP package selection, network component. Follow by types of game that going to provide to the customer, by providing several example of games requirement for making decision on different types of hardware and software to use in gaming centre. The game requirement is an important role that allows gaming centre to choose the suitable hardware for the computer in the gaming centre in order to achieve customer satisfaction. In order to allow customer to play online and LAN games with lowest connection latency, the selection of network topology and architecture is important. Due to the gaming centre is going to implement 30 gaming computer for the customer, the right topology and architecture allow customer to play online and LAN game smoothly. To play an online game with smooth connection, it is required to have good bandwidth of connection speed. Therefore, choosing the suitable package among other Internet Service Provider will be based on the connection speed. To build a complete and working network for the gaming centre, the major component of network cannot be missed out, which is computer, software, network interface device, and transmission media. Each of the components has different responsibility in order for a network to be complete. With the help of research on Internet, the model of device and type of application is recommended base on the specification of the hardware and software. However, these hardware and software may request to change by gaming centre after or before the implementation based on their justification. Assumption Below is some of the assumption of the gaming centre and network that going to implement:- The gaming centre will be providing high-end game to customer. Customers allow playing offline, online, and LAN games in the gaming centre. The gaming centre is capable of hosting tournament for different types of online and LAN games. The computer specification is sufficient enough for most of the high-end game. The connection bandwidth is capable to handle up to 35 computers in the gaming centre. The network topology, architecture and device recommended able to achieve the terms of scalability and flexibility for the gaming centre to expanding the business in future. Limitation There is some of limitation of the network that may require specialist or admin with relevant knowledge to solve the problem. These limitations may require paying extra attention by admin in order to minimize the lost that cause by it. The particular networks fail if the centralized device is encountering a problem. This may affect all computers that connected to the device. The network congestion problem occur when huge numbers of users trying to access the server to obtain the resource from the server. When the server is down or damage, it unable to handle and provide result of request by the customer such as starting a game. 1.0 Chapter 1 1.1 Introduction Wendell Odom (2004, pg.5) states that Network, a combination of hardware, software, and cabling, which together allow multiple computing devices to communicate with each other. In general, network basically means that numbers of computer being attached together in order to communicate and sharing information using cable. However, without proper configuration and supported software, communication and sharing information activities cant perform accordingly. Picture below shows the example of a network. Figure 1.1 Computer Network (http://www.home-network-help.com/wireless-router-as-access-point.html, n.d.) In order to create a successful network, it should consist of several parts, which is computer, software, network interface device, and transmission medium. Without any of the important part mention above, it will not call as a network. Computer is electronic devices that allow users to perform certain task easily compare to perform manually. Software is an application that helps computer to perform most of the task. Network interface device is referring to the device that uses to connect the computer with the internet, example modem, switch, router, and hub. Transmission medium is cable that connects the network interface device with the computer, as well as connects to the internet. People nowadays know that advantage of network is to share resources and information in shortest time and different geographical location. It helps to evaluate the travel time from one location to another location. Moreover, network also helps increased cost efficiency, this is refer to most of the software are published are costly and required certain amount of time to install. With the help of network, they can stored or install the software on a server so that it can be used by different workstation. In the gaming centre, it allow customer to access to the game play online or LAN games with players within or outside the gaming centre. 1.2 Type of Network 1.2.1 Wide Area Network (WAN) The gaming centre will be implementing the Wide Area Network, which is a combination of multiple Local Area Networks to allow customer to play online game as well as LAN game at the same time. Example of the WAN is Internet. It combines all the LAN that connected to the internet which allows users to communicate and sharing resource within the LAN or other LAN that connected to the Internet. Figure 1.2 WAN (http://wally.cs.iupui.edu/n241_06/files/webMag/index.html, n.d) The reason of having WAN for the gaming centre is due to the wide coverage of the network. The only resource needed for the gaming centre to implement is LAN that can access to the Internet, then it is automatically becomes part of the WAN. 2.0 Chapter 2 2.1 Computer Game Mark Stanfield and Thomas Connolly (2008, pg.25) states that The definition of computer games combines the more comprehensive concept of game with the use of computer. The game concept represents a structured or semi-structured activity with goal that players try to achieve and set of rules governing its operation. Base on the definition, game is referring to a well planned structure that consists of objective for anyone that plays it. However, player is required to understand and obey the rules and regulation of the specific in order to achieve the objective and gain achievement. Meanwhile, computer game is mean by the game can only be played using electronic devices which is computer. That the beginning of computer games, there is only offline game available and it required lesser disk space compare to computer games nowadays. Until today, there is plenty type of computer game on the market, such as online games, offline games, LAN games which is local area network games, and every type of computer games had been classified into different categories, for example RPG, FPS, RTS and many more. Offline games is referring to any games that can play by single player and unable to connect through the network and play with other players that playing the same game. An online game is referring to any type of game that can play using Internet and play or compete against other player. Lastly, LAN games is referring to any types of game that can played with other players within the certain area whereby users computer is connected to a same network. However, there are many games that can allow single player as well as multiplayer. Every game had its own requirement in order for player to play the games without any foreseen problem, the requirement divided into different categories, such as type operating system, processor, and type of graphic card, numbers GB of RAM, hard disk space, and also DirectX version. However, there is minimum requirement and recommended requirement which allow player to know that the specific game is suitable to play on their computer or not. Minimum requirement is to allow users to run and play the game in a normal performance and loading speed. As for recommended requirement, users able to run and play the game smoother in terms of performance and higher loading speed. As a LAN gaming centre, it is necessary to have various type of games provided to customer according to their favourite, and to satisfied the customer, there is certain level of knowing the games requirement and specification so that the centre able to choose the right hardware and software for the computer in the centre. By taking some example of the games requirement, it should be able to help in choosing the proper gadget for the computer. 2.2 Types of Game The game chosen to review the game requirement and use it as a reference for selecting the suitable hardware and software for the computer, Starcraft II, Warcraft 3, Counter-Strike: Source, Sudden Attack SEA, and Devil May Cry 4. The example of game chosen included online games, offline games, and LAN games. Online game example for this documentation is Sudden Attack SEA, which is first person shooting game and can only be played while connected with internet. Offline game is Devil May Cry 4 which is role playing game only for single player. Lastly LAN game, the example of game chosen is Starcraft 2 and Warcraft 3, a real time strategy game, and Counter-Strike: Source is a first person shooting game. These three games can be played with other player while connected to the network. However, it can be consider as offline, online game as well, due to these game are able to play with single player or connected to internet and play with or compete against other player. 2.3 Games Requirement Figure 2.1 Sudden attack SEA (online) (http://www.gx.com.sg/Blog/Blog.aspx?id=7ab57b16-fa13-4f2a-a937-0fb14368fec3, n.d) System Minimum Requirement Recommended Requirement CPU Intel Pentium 4 1.8GHz or above AMD Athlon XP2100 or above Intel Core 2 Duo or above AMD Athlon 64 X2 or above Memory 1GB or above 2GB or above (Win Vista/7) 2GB or above 4GB or above (Win Vista/7) Video Card 128MB or above 256MB or above Microsoft DirectX 9.0c compatible Graphic Card Operating System Windows 2000/XP/Vista/7 DirectX Microsoft DirectX 9.0c or above Hard Disk Space 3GB free space after game installation Table 2.1 Sudden Attack requirement (http://suddenattack.asiasoftsea.net/04-download/04-download_01_01.aspx, n.d) Figure 2.2 Devil May Cry 4 (offline) (http://cineclubecovilha.com/torrent/torrent/Devil-May-Cry-4-DVDDL-Full-PC-Gamedaa/2905/0.html, n.d) System Minimum Requirement Recommended Requirement CPU Intel Pentium 4 processor or better Intel Core 2 Duo processor or better Memory 512MB 1GB Video Card NVIDIA GeForce 6600 series or better NVIDIA GeForce 8600 series or better Operating System Windows XP service pack 2 Window Vista Hard Disk Space 8GB Drive DVD-ROM Drive Table 2.2 Devil May Cry 4 requirement (http://devilmaycry.org/243/devil-may-cry-4-pc-system-requirements.html, n.d) Figure 2.3 Starcraft II (LAN/Online/Offline) (http://www.keys4.me/starcraft-2-ii-wings-of-liberty-eu-cd-key-pc.html, n.d) For Windows OS System Minimum Requirement Recommended Requirement Operating System Window XP/Vista/7 (latest service pack) Window Vista/7 CPU 2.6GHz Pentium IV or equivalent AMD Athlon processor Dual Core 2.4GHz processor Graphic Card 128MB PCIe NVIDIA GeForce 6600 GT or ATI Radeon 9800 PRO or better 512MB NVIDIA GeForce 8800 GTX or ATI Radeon HD 3870 or better RAM 1GB (1.5GB for Window Vista/7) 2GB Hard Disk Space 12GB Others (hardware) Keyboard/mouse, Internet Connection Resolution Minimum 1024720 display resolution DirectX DirectX 9.0c Table 2.3 Starcraft II: Wings of Liberty requirement (for Windows) (http://us.blizzard.com/support/article.xml?articleId=26242locale=en_US, n.d) For Mac System Minimum Requirement Recommended Requirement Operating System Mac OS X 10.5.8, 10.6.2 or newer Mac OS X 10.6.5 or newer CPU Intel Processor Intel Core 2 Duo processor Graphic Card NVIDIA GeForce 8600 GT or ATI Radeon X1600 or better NVIDIA GeForce 9600M GT or ATI Radeon HD 4670 or better RAM 2GB 4GB Hard Disk Space 12GB Others (hardware) Keyboard/mouse, Internet Connection Resolution Minimum 1024720 display resolution Table 2.4 Starcraft II: Wings of Liberty requirement (for Mac) (http://us.blizzard.com/support/article.xml?articleId=26242locale=en_US, n.d) Figure 2.4 Counter-Strike: Source (LAN/Online/Offline) (http://www.moddb.com/games/counter-strike-source, n.d) For Windows System Minimum Requirement Recommended Requirement CPU 1.7GHz processor Pentium 4 processor (3.0GHz or better) RAM 512MB 1GB Graphic Card DirectX 8.1 level graphic card (Requires support for SSE) DirectX 9 level graphic card Operating System Windows 7 (32/64-bit) / Vista / XP DirectX DirectX 8.1 or above DirectX 9 or above Table 2.5 Counter-Strike: Source requirement (for Windows) (http://store.steampowered.com/app/240, n.d) For Mac System Minimum Requirement Operating System OS X version Leopard 10.5.8 Snow Leopard 10.6.3 RAM 1GB Graphic Card NVIDIA GeForce 8 or higher ATI X1600 or higher Intel HD 3000 Others (hardware) Mouse, Keyboard, Internet Connection Table 2.6 Counter-Strike: Source requirement (for Mac) (http://store.steampowered.com/app/240, n.d) Based on the example of game requirement shown above, it clearly shows that different game have its own minimum and recommended requirement in order to play the game smoothly. Games requirement are usually based on previous version of graphic card or processor that already in the market to allow more player to play the games with their current computer. It also shows that different year of published the game may affected the requirement directly. With the example given for different games requirement, it helps the gaming centre to choose the right hardware for the gaming computer. 3.0 Chapter 3 3.1 Topology The topology choose to implement in the gaming centre is star topology. Star topology is one of the most common topology that used in current days. In star topology, every device is connected to a centralized device such as switch, router, or hub via Ethernet cable. This topology arrangement creates a point-to-point network connection between two devices and overall gives the appearance of a star. The reason of implementing the star topology in the gaming centre is the level of flexibility and expandability is high. Multiple star can combine as a hierarchical star and connectivity of the network on one particular computer will not affected other computer that connected to the same network unless the whole centralized device or main cable connected with the modem or router is damaged. Figure 3.1 Star Topology (http://tjliu.myweb.hinet.net/COA_CH_12.htm, n.d) 3.2 Architecture The architecture that suggested implementing in the gaming centre would be client-server architecture. Client-server architecture is referring multiple user computer connect and interact with one or multiple server that connected within same network. This architecture allows multiple users to submit request at the same time, and the server able to react to the request and provide result to user requested accordingly. Server are usually powerful machine due to the workload is heavy and need to be complete within short period of time. The reason of implementing client-server architecture to the gaming centre is due to the resource will be kept in the server that connected to the same network with the users computer. If the gaming centre decides to expand and add more computers to the network, it would be very easy to configure and it wont affect other clients connection with the server. Figure 3.2 Client-server (http://www.javaworld.com/javaworld/jw-10-2001/jw-1019-jxta.html, n.d) 3.3 Internet Service Provider ISP is the companies that provide Internet service to the people by subscribe various packages that give various amount of Mbps and services to the customer. Some ISP also provides modem/router for subscribing their package. The ISP that suggested is TM. Currently TM is promoting high speed broadband called Unifi, these package allow customer to enjoy the speed from minimum 5Mbps up to 20Mbps. For the gaming centre, the BIZ 10 package is sufficient enough for gaming. Below shows some of the key features of the BIZ 10 package:- Download and upload up to 10Mbps 1 fixed IP Unlimited usage 2 online guard plus 2 ishield plus 3.4 Component of Network In earlier part of documentation, it states that a complete network consists of 4 major components. The components are, computer, software, network interface device, and transmission medium. If lacking either one of the components, a network will not complete. 3.4.1 Computer Computers, a component that responsible on dealing with the user and connection, to setup, configure and maintain the network. Gaming centres main objective is to provide good service in terms of game playing satisfaction for customer to gain profit. In customer view, they usually hope to play game without any connection latency problem, or display lagging problem during the game. And also external hardware such as keyboard, mouse, and headphone also must be in good quality to satisfy the customer. In order to achieve the objective, choosing the right hardware for the computer would be important. Due to the computer hardware is updating model and performance frequently, there is impossible for a gaming centre to get a set of latest hardware for computer in the gaming centre, because it is costly. In this case, the computer that installed in the gaming centre would be a customize computer, which means the CPU itself is installed based on buyers need. Therefore, the computer specificat ion for the gaming centre is shown on table below. System Component Device model Operating system Windows 7 Ultimate 32-bit CPU Intel Core i5 650 @ 3.20GHz RAM 4GB Graphic Card ATI Radeon HD 5670 DirectX DirectX 11 Table 3.1 Computer Specification In order for gaming centre to keep the important data and information such as finance report or employees profile. It is highly recommended to implement server in the gaming centre. Server also allows gaming centre to store the games that going to play by the customer. Customer able to play any games that already installed in the server of the gaming centre, by choosing and click on the games shortcut inside the computer, customer are able to play the game freely. The model of server recommended to implement in gaming centre is Dell PowerEdge R515 2U Rack Server. It is suitable for storing database, application, email and others file. This model of server consists up to 25TB of internal storage space. And is easy to manage with the help of dell management console, and interactive LCD screen and other features to allow administrator to monitor and maintain the server frequently.

For the server, it is recommended to install Windows small business server 2008. This particular operating system support internet connectivity, internal Web sites, remote access, file and printer sharing, backup and restore to secure all the resource that installed in the server. For securing the computer in the gaming centre from virus attack and hacking, the antivirus also required to install. The KasperSky anti-virus 2011 is the latest and suitable to protect the computer in gaming centre. In order to maintain and configure the network easily, the Cisco routers are integrated with Cisco IOS which is an all-in-one network operating system that allow user maintain the network using Cisco IOS Command Line Interface (CLI). With the help of Cisco IOS, administrators can configure, monitor and troubleshoot the system easily. Last but not least, all the games software or client need to installed into the server to allow customer to access. The reason of installing all games client is to save time on install and maintain. When a games encounter a problem, admin can solve it on the server side compare to install in each pc, admin have to solve the same problem over and over again when problem encounter. 3.3.3 Transmission Media The transmission media used for the gaming centre is Unshielded Twisted Pair (UTP) and wireless. UTP is the most commonly used media for connecting from device to device in various type of network. It consists of eight individual copper wires and each of the wires are covered by an insulating material and twisted around each other. Upon searching for information regarding UTP (CICSO, 2004) has shown various category of UTP cable. Category 1 Used for telephone communications. Not suitable for transmitting data. Category 2 Capable of transmitting data at speeds up to 4 megabits per second (Mbps). Category 3 Used in 10BASE-T networks. Can transmit data at speeds up to 10 Mbps. Category 4 Used in Token Ring networks. Can transmit data at speeds up to 16 Mbps. Category 5 Can transmit data at speeds up to 100 Mbps. Category 5e Used in networks running at speeds up to 1000 Mbps (1 gigabit per second [Gbps]). Category 6 Typically, Category 6 cable consists of four pairs of 24 American Wire Gauge (AWG) copper wires. Currently the fastest standard for UTP. The reason of having UTP to be implement in the gaming centre is due to the cost for the cable is cheap compare to other type of cables and is easier to install as well. It also can support multiple signals travelling through the same cable. Figure 3.3 Unshielded Twisted Pair cable (http://www.tech-faq.com/utp.html, n.d) 3.4.4 Network Interface Device For network interface device, is the component that act as the middle man in terms of business, it is connected with the users computer, and also Internet to handle data transferring, such as modem, router, switch, hub, and bridges. The device that implement in the gaming centre is modem, router, and switches. Each three device have different usage, modem, allow users to gain access to the internet which usually provided by the Internet Service Provider company upon subscribe the package. Router, to allow more than two users to connected and access to the internet, it also allow users to form a LAN. Switches, allow multiple users to communicate and sharing resource within the network. The router that recommended implementing in the gaming centre is Cisco 2951 Series Integrated Router. This model of routers has the feature shown below:- 3 integrated 10/100/1000 Ethernet ports with 1 port capable of RJ-45 or SFP connectivity 2 service module slots 4 Enhanced High-Speed WAN Interface Card slots 3 onboard digital signal processor (DSP) slots 1 internal service module slot for application services Fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE Security Onboard hardware acceleration for VPN encryption Secure collaborative communications with Group Encrypted Transport VPN, Dynamic Multipoint VPN, or Enhanced Easy VPN Integrated threat control using Cisco IOS Firewall, Cisco IOS Zone-Based Firewall, Cisco IOS IPS, and Cisco IOS Content Filtering Identity management using authentication, authorization, and accounting (AAA), and public key infrastructure Voice High-density packet voice DSP module, optimized for voice and video support Standards-certified VoiceXML browser services Cisco Unified Border Element capabilities Cisco Unity Express voicemail support.

Carlsberg Background and History in Malaysia Essay

The Carlsberg Group is a Danish brewing company founded in 1847 by J. C. Jacobsen after the name of his son Carl. The headquarters are in Copenhagen, Denmark. The company’s main brand is Carlsberg Beer, but it also brews Tuborg as well as local beers. After merging with the brewery assets of Norwegian conglomerate Orkla ASA in January 2001, Carlsberg became the 5th largest brewery group in the world. It is the leading beer seller in Russia with about 40 percent market share. In 2009 Carlsberg is the 4th largest brewery group in the world employing around 45,000 people. Carlsberg was founded by J. C. Jacobsen. The first brew was finished on 10 November 1847. Export of Carlsberg beer began in 1868. Some of the company’s original logos include an elephant (after which some of its lagers are named) and the swastika. Jacobsen set up the Carlsberg Laboratory in 1875 which worked on scientific problems related to brewing. It featured a Department of Chemistry and a Department of Physiology. The species of yeast used to make pale lager, Saccharomyces carlsbergensis, was isolated at the Laboratory and was named after it. The laboratory was part of the Carlsberg Foundation until 1972 when it was renamed the Carlsberg Research Center and transferred to the brewery In December 1969, Carlsberg Brewery Malaysia Berhad (Carlsberg Malaysia) began brewing Carlsberg Green Label beer locally in 1972.

Medical Marijuana

Dustin Flynn Assn# 5 Example/Comparison/Argumentative Inductive TREAT THE SYMPTOMS, NOT THE INJURY For centuries marijuana has been used by the top doctors of their time. And until recently, the past thirty years, the actual physical effects were unknown. Over the past three decades Science and Medicine have been researching what useful and healing effects this herb has, if any. Through my research I have found what I had only thought to be true. Marijuana does have great medicinal use. It is currently being used for an array of illnesses and injuries. But its most effective uses are focused in treating the onsets of AIDS and the symptoms from chemotherapy in the treatment of cancer. Those onsets and symptoms are anxiety, declining appetite, nausea, and general pain. These ailments bare a strong resemblance of the symptoms of Traumatic Brain Injury, or TBI. It is because of these resemblances that I have come to the conclusion that marijuana could be the best treatment for the symptoms associated with TBI. In this article I am going to explain the historical uses of marijuana, the symptoms of TBI, the current treatments for TBI, how marijuana works, and the valued effects that marijuana can provide for persons diagnosed with TBI. As I said before, marijuana has been used for centuries for medicinal use. The first uses are dated back before 4000 BCE, (Before Common Era), as a food source because of its protein and omega 3 content. â€Å"The first recorded medicinal use was in 2737 BCE. Emperor Shen-Nung of China suggested it be used for the treatment of constipation, menstruation cramps, rheumatism, malaria, gout, and absentmindedness. †(Sanna, 18) Now if we look at some of these ailments and diseases and take some of the symptoms that are associated with them. We can see that they are similar to symptoms associated with TBI. Take rheumatism for example, most people associate rheumatism with rheumatoid arthritis or osteoarthritis. But in its most simple diagnosis it is described as general pain and weakness, which is a common symptom with a major diagnosis of TBI. Patients with a major diagnosis can be in, sometimes, constant pain, because the receptors in the brain that regulate pain are damaged due to their TBI. So centuries before things were the way they are now, there was a suitable prescription for one major symptom associated with TBI. Now lets look at absentmindedness, we cannot be sure what the exact definition of this could have been in 2737 BCE. But what we can take from this is that even back then it was acknowledged that marijuana was a suitable prescription for issues concerning the brain. The Emperor was able to see a beneficial change in mood, memory, or thought process. Something made a significant change for him to recommend marijuana. Marijuana became very popular medically in China and eventually made its way to Europe. Around 500 BCE marijuana reached Europe, and with its long reputation as a medicating plant, the Europeans immediately put it into personal testing. â€Å"Doctors of that time separated marijuana into two groups, weedy, and cultivated. †(Sanna 18) The weedy marijuana was best used for curing hard tumors. And the cultivated marijuana was best used for soothing and curing coughs. Now that might seem like a big difference in the severity of symptoms, but the Doctors of that time tested marijuana with almost every ailment and disease that was brought to their attention. Again as before, if we look at one of these symptoms and compare it with symptoms of TBI we can see the benefits. As a patient with any severity of TBI there is a higher risk of developing cancerous and malignant tumors in the brain. â€Å"Doctors and Scientists are unsure of why this is associated with TBI†(Chew 851-878), but their research shows that the risks are there. Marijuana has certain properties called â€Å"Cannabinoids† (Richmond) that actually convince tumors anywhere in the body to commit suicide. The reason this is so beneficial for patients with TBI, patients who are at higher risk of developing tumors in the brain, is because the â€Å"Cannabinoids† in marijuana link up with our bodies own â€Å"Endocannabinoid System†, (Richmond) a system which naturally produces cannabis in our bodies, and fight tumors in the brain. â€Å"Tumors in the brain are the hardest forms of tumors in the body to cure, because they are so hard to treat. (Chew 851-878) It is extremely dangerous for Doctors to operate on the the brain, and normal chemotherapy will usually kill the patient before it kills the tumor due to what is called the â€Å"blood/brain barrier†. (Chew 851-878) â€Å"The blood/brain barrier† is a filter of sorts, the brain has to have whole blood and oxygen to operate properly. The â€Å"blood/brain barr ier† filters out toxins such as the ones used in chemotherapy, and is very selective in what it lets in the brain. The â€Å"Cannabinoids† found in marijuana are able to pass through that â€Å"blood/brain barrier† freely which allows it to do its job and destroy tumors, naturally. Let us skip ahead to around the ninth century. Marijuana has gained popularity as a medicine everywhere east of the Atlantic. And in â€Å"India it was claimed to cure dandruff, Sexually Transmitted Diseases, leprosy, insomnia, and tuberculosis. † (Sanna 18) As far as these ailments and diseases go, insomnia is the one symptom that is shared with patients of TBI. Many patients with any severity of TBI experience insomnia, or other sleeping disorders. Research today supports the Indians theories that marijuana can and does treat insomnia. Now to bring it home, in the United States from 1850 to 1942 marijuana was actually listed in the U. S. Pharmacopeia, which is the list of government approved and recommended drugs for use in treatment of patients. At that time marijuana was stilled called cannabis and was being used in the treatment of labor pains and nausea. But in 1942 the United States Government declared cannabis, (marijuana), a level one narcotic and was made illegal to prescribe, posses, or cultivate. Out of the two ailments that marijuana was being used for at that time, nausea, is a direct symptom of TBI. Patients with any severity of TBI can have chronic nausea brought on by a injured equilibrium. This injury can have the affects of severe motion sickness even when a patient is standing or sitting still. Finally in 2003, â€Å"Canada became the first country in the world to offer medical marijuana to patients† (Sanna 18), initially if was for the treatments of symptoms associated with cancer and AIDS. Since 2003 some states in the United States have followed that example, California being the first, but since medical marijuana is still Federally illegal patients, Doctors, and pharmacies can be arrested, closed, and have their licenses removed. Which makes the freedom of prescribing and receiving medication difficult. â€Å"More than 5. 3 million people, or approximately two percent of the U. S. Population, are living with disabilities resulting from Traumatic Brain Injury. † (Chew 851-878) Here is a list of some of the difficult symptoms, both mentally and physically, that these patients could be facing on a daily basis. Mentally; Attention Deficit Disorder, memory loss, depression, easily agitated, irritability, unprovoked acts of aggression and violence, mania, psychoses, and mood swings. These are just the main mental struggles these patients possibly face suffering from TBI. Physically; Random loss of consciousness, disorientation, headaches, general pain, loss of balance, nausea and vomiting, blurred vision, ringing in the ears, bad taste in the mouth, sensitivity to light and sound, sleeping disorders, seizures, and loss of bladder and bowel control. With all of these symptoms these patients could be facing it is hard to think of the cocktail of medicine that these patients could be forced to take on a daily basis. Currently pharmaceutical companies try only to treat one symptom at a time, it makes for a bigger business and more profits, which leaves the patient, especially in this case, on the long road to recovery. Currently there are over thirty one different drugs being used just to treat the mental symptoms associated with TBI, with no one drug being able to treat multiple symptoms. So that means in most cases these patients are using at least two drugs on a trial basis at any given time, and if there is no change in symptoms they are simply switched to another medication until they achieve satisfactory effects. Just imagine the strain these patients are putting on their livers just to ease the symptoms of a Traumatic Brain Injury. And this is how it is for every patient, Doctors are still unable to come up with what works best for certain symptoms. With that uncertainty, patients become human test subjects, and each Doctor becomes a researcher. And in some cases of mild TBI, the medication that is prescribed has side effects that out weigh the patients initial symptoms. Why would anyone want to take medicine to stop vomiting if the outcome was constipation; and if someone has loss of balance, the medicine prescribed could make them extremely drowsy and have them sleep all day. The world of pharmaceuticals is expensive, representatives from these companies turn Doctors in to salesmen and spokesman. And the outcome is high cost prescriptions that cost the patient and the insurance companies millions of dollars every year, not to mention the huge amount of money that these companies receive from the government every year to research and produce new â€Å"miracle† drugs. Marijuana is made up of over 421 natural chemicals, of which over sixty are Cannabinoids†. (Richmond) Now as I mentioned earlier, we all have what is called a â€Å"Endocannabinoid System†, which regulates the â€Å"Cannabinoids† that are body naturally produces, that is right our bodies produce cannabis. The natural â€Å"Cannabinoids† in our body are used almost like our immune system. When there is something wrong in our bodies an alarm goes off, like when we get a cold, and our immune system rushes in and attacks that bad thing trying to kill it. Our â€Å"Endocannabinoid System† works almost the same way but it is able to fight many bad things at once, while also protecting our good cells, regulating proper brain function, and leveling our anxiety. Our â€Å"Endocannabinoids System† is very advanced, it is mostly gathered in the brain, but it spans through the liver, the bones and the nervous system. There are four main â€Å"Cannabinoids† that Doctors and Scientists have been able to focus on because of there over all medicinal uses. The first and most recognizable is Delta 9-Tetraydrocannabinol or THC. THC is a psychoactive component that mimics and enhances the bodies own Endocannabinoids System† (Richmond); which widely effects mood, appetite, sleep, and good cell protection. So for patients who have been diagnosed with TBI that have appetite loss, sleeping disorders, and mood swings, this component of marijuana can greatly help. The second main â€Å"Cannabinoid† is Cannabidol or CBD. à ¢â‚¬Å"CBD is a non-psychoactive component that enhances the sedative effect† (Richmond), which is good for patients diagnosed with TBI specifically dealing with insomnia. It also is an excellent anti-inflammatory, and bone growth stimulant. It has anti-diabetic and anti-bacterial capabilities, it also has anti-proliferative anti-cancerous capabilities, which means it helps to kill malignant tumors. It is a anti-spasmodic, which fights against muscle spasms and seizures. It is a neuroprotectant that helps regulate pain due to nerve damage, and it is a anti-psychotic, which helps in the fight against schizophrenia, these last three symptoms are directly associated with TBI. The third main â€Å"Cannabinoid† is Tetrahydrocannabivarin or THCV. THCV is a non-psychoactive component† (Richmond) that helps the other main â€Å"Cannabinoids† to be delivered faster, and to the correct spots where the â€Å"Endocannabinoid System† is possibly running low on ammunition. This component could extremely help patients diagnosed with TBI to get the correct â€Å"Cannabinoids† where they are needed quicker. But its downfall can be that if there is to much THCV in the certain strain of marijuana, that the effects of the other â€Å"Cannabinoids† will be short lived. It is also a very effective protective/preventive against type two diabetes. The last main â€Å"Cannabinoid† is Cannabichromene or CBC. â€Å"CBC is a psychoactive component that is a lower strength Cannabinoid† (Richmond) which is a excellent anti-depressant, anti-inflammatory, bone growth stimulant, that strongly prohibits tumor growth in Leukemia and breast cancer. There are few solid arguments against the evidence that has been shown in today's scientific research. The most popular argument about using marijuana medicinally is that when smoked we are actually introducing tar and other cancer causing agents into our body. But research shows that there is absolutely, one hundred percent, no evidence to support the theory of that. In fact it is quite the opposite. Also to help against that argument, there are now ways of ingesting marijuana without smoking it, it can be made into a butter and cooked into everyday foods. It can be made into a spray form that is applied directly under the tongue, and it also comes in a very low dosage pill form which is currently used only for nausea and vomiting associated with cancer and AIDS treatments. Another argument is that there is no way to regulate the dosage on marijuana because there is such a difference between strains of the marijuana plant, someone could overdose. Scientist have proven that if someone was to overdose on marijuana that the initial reaction the body will put off is to just go to sleep, that is it. The patient would just sleep it off as if it were a hangover, minus the headache in the morning. Also the longest possible side effects will last with marijuana is only a few hours, even if there is a overdose situation. In the thousands of recorded years of marijuana use, for recreation or medically, there has not been one recorded death, no one has died just from using marijuana. In fact scientists have come up with what it would take for a person to actually die from smoking marijuana. â€Å"A person would have to smoke 1500 pounds of marijuana in about fifteen minuets, and they would probably die of asphyxiation. † (Richmond) The only other argument that has any solid ground is that, at least in the United States, marijuana is still federally illegal to posses, cultivate, and distribute. And to that argument, the only thing I can say is that it will take the states themselves to stand up and take care of their own people, and provide them with the medicines they need, then eventually the federal government will have to fall in line. In seeing this evidence of marijuana and its scientifically proven medicinal uses, most people can not believe it is true. People cannot believe that there is one drug that is able to treat so many things at once. The truth is that for thousands of years our body has produced this drug on its own, and with the growth of humans not only intellectually but physically, and industrially. We have created a world that has taken our â€Å"Endocannabinoid System† and made it in some cases useless. We are introduced to so many toxins in our food, in our air, and even in our medications that we have not been able to upgrade our â€Å"Endocannabinoid System†, like we have with our immune system ,with the introduction of vaccines and certain pollutants. Thousands of years ago, before we created most of the toxins of today's world, our â€Å"Endocannabinoid System† was perfectly able to combat along with our immune system against most of the ailments and everyday aches and pains. We have not steadily increased our intake of â€Å"Cannabinoids† like we have with other things. We are still operating at a level suitable for life thousands of years ago. With the introduction of marijuana into our bodies we will not only be able to fight against these tough symptoms associated with TBI, but we could possibly be able to prevent and possibly cure diseases like cancer, rheumatoid arthritis, osteoporosis, and many other everyday symptoms that we are all faced with in our life.

J. Mind Altering Weed Broomall: Mason Crest, 2008 Print What if Cannabis could Cure Cancer. Dir. Lee Richmond. Lee Richmond Films LLC 2010 Film Medical Marijuana Marijuana is the most commonly used drug in the United States. However, it has singular distinction of being both a commonly used illegal substance and also a legally prescribed medical substance. Marijuana will always be used for private reasons or for medical purposes. Isn’t it a good thing that children not even four years of age are offered medical marijuana to cure diseases such as epilepsy? Seth Ammerman and Courtney Williams are writers for New’s Digital weekly. These articles were published in December of 2012. Courtney and Seth state their point of view about medical marijuana.Should medical marijuana be prescribed to children? People who are against medical marijuana say that there is not enough scientific research to support prescribing cannabis. Medical Marijuana is only legalized in some states because everyone has their own right to state their own opinion. Not every state agrees. In every cannabis plant there are cannabinoids, which are the THC and CBD ch emicals. THC is the chemical that drug cartels use illegally. Cannabidol is the chemical that is put into medical marijuana. Most dispensaries do not get tested for there cannabinoid content.The chemical is usually unknown. One of the major issues to prescribing a child medical marijuana is the cause of addiction. Marijuana can alter the brain into wanting the drug all the time. The younger a child starts to use cannabis, the child may never want to stop. (Ammerman 2) Of course there are side effects that may give you a negative feeling about using medical marijuana, such as anxiety, paranoia, and depression. While some people say what if. There are others who take a risk and take a chance. Parents who have chosen cannabis to treat their child have raised their eyebrows.A two year old had to go through 39 hours of surgery, while under anesthesia for 42 days. The doctor sent the child home on hospice and morphine. The child’s pediatrician suggested cannabis. The two year old i s now alive and free of cancer. (Williams 2) Marijuana contains of Vitamin C and Vitamin D. Vitamin F is also found in medical marijuana that contains a cannabinoid acid, which allows the cells in your brain to treat the disorder. (Williams 2) In my own opinion, I’m for medical cannabis. Children can always stop themselves from becoming addicted if they use the drug correctly and they do not abuse it.There are millions of people today using cannabis as medicine. While children are throwing a million and one pills down their throat and nothing is working. You can never doubt medical marijuana. Medical marijuana will be able to cure anything. Should medical marijuana be prescribed to children? Yes, it should. Medical marijuana is a touchy subject. There may not be enough scientific evidence, but who needs evidence when there is proof. All you have to do is take one look at a child who is free of cancer from using medical marijuana. That child is the proof.

Nursing Reflection Essay - 1419 Words

Reflection on a clinical Skill This essay will discuss a clinical skill in which I have become competent in practicing as a student nurse. I will use a reflective model to discuss how I have achieved the necessary level of competence in my nurse training programme. The reflective model I have chosen to use is Gibbs model (Gibbs 1988). Gibbs model of reflection incorporates the following: description, feelings, evaluation, analysis, conclusion and an action plan (Gibbs 1988). The model will be applied to the essay to facilitate critical thought, relating theory to practice where the model allows. Discussion will include the knowledge underpinning practice and the evidence base for the clinical skill. A conclusion to the essay will†¦show more content†¦My mentor said that this was acceptable and I continued to administer the injection, omitting the use of the alcohol wipe. On the previous occasions when I had administered IM injections I had not cleansed the site and had never been instructed to adopt this practice. I am now going to enter into the second stage of Gibbs (1988) model of reflection, which is a discussion about my thoughts and feelings. I was aware of being under the supervision of two qualified nurses and this made me feel very nervous and self conscious. Once my mentor questioned my practice, concerning skin cleansing, I became even more aware of feeling nervous and under pressure. The patient was present and I did not want the patient to feel that I did not know what I was doing. I thought that as I had been observed carrying out this clinical procedure on many other occasions then my practice must have been seen to be correct. I was now feeling very confused about the use of alcohol wipes in the administration of IM injection. I was also concerned that the practice of the qualified nurses was so inconsistent, which led me to evaluate the whole process. Evaluation is the third stage of Gibbs (1988) model of reflection and requires the reflector to with state what was good and bad about the event. I was aware that research by Workman (1999) suggests that the use of skin cleansing wipes is inconsistent and not necessary in IM injections if the patient appears to be physically cleanShow MoreRelatedNursing reflection.12855 Words   |  52 PagesReflective Essay This essay will look at reflection on a critical incident that has promoted a positive outcome.
