[IERW#04] Importance of VR technology in Psychiatry

VR technology has become an indispensable technology in education, medical, and architecture as well as games. VR technology enables people to experience their virtual reality realized within a computer by using their special glasses and gloves. The use of VR in the medical field is noteworthy among the various areas. Especially, since many modern people are suffering from various mental illnesses due to fatigue and stress, psychiatric fields emphasize the importance of VR technology to treat them effectively.

In the psychiatric field, VR technology is effective in the treatment of various phobias such as claustrophobia and public speaking phobia. For example, a person who has a specific phobia is trained to be properly exposed to the fear through experience virtual reality. Such training can be effective as treating phobias because it is safe, can be stopped immediately if necessary, or can repeat the same conditions. In March 2016, Samsung Electronics carried out a campaign called "Be Fearless" in Europe and the Middle East using gear VR to alleviate phobias. It is a way to implement the VR environment, such as fear of heights and 27 patients from various countries participant the campaign. As their heart rate measurement, average fear of patients decreased by 23.6% after 2 weeks of experiment. VR technology is a vital technology for modern people because of the increase of various phobias due to extreme work stress.

A vital area of VR technology in the psychiatric field is the treatment of Post-Traumatic Stress Disorder (PTSD). PTSD is a disease that feels frightened and feels trauma after experiencing events such as war, natural disaster, crime, and terrorism. Accordingly, VR technology has been treating PTSD based on the principle of prolonged-exposure therapy, which has proven to be the most effective treatment for PTSD treatment. In the past, for prolonged-exposure therapy, the patient was asked to imagine and recall the events by the doctor. However, the patient was reluctant to recall the memory .According to the NCBI study, if the patient does not visualize the memory of trauma vividly, effective therapy is difficult .This is why VR technology is effective for prolonged-exposure therapy. Instead of asking the patient to recollect his memory, ones use the virtual reality to get into the situation.

The VR technology has been applied to soldiers who have experienced trauma in the Iraq war. The soldier wears a display (HMD) on his head and enters a realistic war in Iraq.  Through a variety of options, counselors can create a variety of situations in which soldiers have caused trauma. As a result, soldiers were able to vividly imagine the war, find the cause of the trauma, and effectively treat it. Although wars are rare these days, innumerable victims are on the increase as various social crimes and terrorism. Therefore, VR technology has become a very important technology to effectively treat them.

VR technology is an essential technology to effectively treat modern people suffering from various mental illnesses by chronic fatigue and stress. Because this mental illness may cause another social crime it must be treated. In addition, it is our duty to help the innocent victims of terrorism and social crime overcome the trauma. Therefore, VR technology is a necessary technology in modern society in terms of crime prevention and effective psychiatric treatment.

[IERW #3] The Hybrid Car for Earth and Future Generations

Due to continuous development, the environmental pollution problem of the Earth is getting worse. Thus, many governments have made various domestic and international efforts. Most focusing is on efforts to reduce Carbon emissions by limiting vehicle using. Because greenhouse gases from cars are making air pollution worse on Earth. Such air pollution can also cause environmental problems such as global warming. In addition, Petroleum and Gasoline used in automobiles are limited, so there is a problem that cannot satisfy future generations' needs. So, we have to use hybrid cars as a solution for the problem of air pollution and resource depletion on Earth

Many companies have launched several low-pollution vehicles as a part of their carbon emissions regulations. Among them, 'hybrid cars' running on electric motors and small engines have the lowest CO2 emissions. The hybrid car is a vehicle that has two or more engines together. Generally, the internal combustion engine and the battery engine are installed at the hybrid car. In other words, because it has a gasoline or diesel engine and an electric engine, it can reduce emissions of nitrogen oxides, carbon monoxide, etc. up to 90% compared with general automobiles. According to the Hybrid car released by Hyundai Motor Company, it has reduced CO2 emissions by about 28%, which is equivalent to the amount of carbon dioxide absorbed by 1200 trees of 30-year-old pines. Therefore, modern people who are inevitable to use automobiles should use hybrid cars as an alternative and solve the problem of global warming by reducing carbon emissions.

Hybrid cars solve not only air pollution problems but also resource exhaustion problems. Hybrid cars are also famous for their advanced fuel economy. When the hybrid stopped, the ignition is automatically turned off, preventing fuel loss in standby mode. In addition, when the engine is switched on, it uses a battery engine rather than an internal combustion engine, so that it is more energy efficient than regular cars. This high fuel economy reduces the use of petroleum, so we can pass down more resources to future generations. Therefore, we must use hybrid cars to solve the resource depletion problem.

Like this, hybrid cars are a good alternative to air pollution and resource depletion. Therefore, a government have to encourage more people to use hybrid cars by various way. For example, economic benefits such as discount tolls, public parking lots, and so on must be provided to hybrid car users because hybrid cars are more expensive than regular cars. Also, many countries offer these benefits, yet, governments must strive to provide more benefits as a reward for environmental protection.

To reduce pollution, the best thing is to use public transportation, bicycles, etc. However, if you inevitably need a car because the modern people cannot help using these days, what about try to use hybrid cars, which are green vehicles, instead of ordinary cars to pass down a better global environment and more resources to future generations. Although promoting the use of hybrid cars can be challenging for both the government and users, this should be mandatory, not optional.

[IERW #2] The Martion

 The location of movie is very important because it determines the fate of the protagonist. The movie, MARTION is about one man who is called Watt trying to survive alone on the Mars. Actually, the Mars has a close relationship with the Earth than the other planet as to be called brother. The fate of Watt would have been changed if the location of the movie was another planet not the Mars. Likewise, the Mars is very important element of the movie, because it is the main reason why Watt was left on Mars alone as well as he can return to Earth safely.  

  Sandstorms caused by the unique climate of the Mars that has the huge temperature difference and dry weather make Watt left alone on the Mars. NASA team 3 encounterd the notorious dust storm while explore the Mars. The speed of sandstorms is hard for human to bear because it is about 100m per 1 sec. Due to this dust storms, Watt were left alone on the Mars, apart from members and the story is begun. If without the unique climate on the Mars such as hazardous sand storms, Watt might not be remained alone on the Mars.

  The Watt was able to come back alive, because Mars and the Earth have similar condition. Mars is the most close to the Earth so that the temperature is also similar with the Earth. This weather condition of Mars is an important element that Watts can be rescued from the Earth within 587 days and survive on the Mars as a result. If the background of the planet that he stayed was very different with the earth, he could not be rescued. Because the other plant which is farther than the Earth would need longer time to rescue him, he might be died due to lack of the food. Besides, Watts could live in the Mars because of an appropriate temperature which is 50 degrees at the lowest that is similar with the Antarctica of the Earth and 30 degrees at the highest.  

  Martion could not be set in any other plant. Because of the sandstorms that exist only on the Mars, Watt had been left alone. In addition, the other plants such as the Venus, Jupiter were so far from the Earth that it would take longer time to rescue him. As well as the temperature of the Venus, Jupiter is about 800 degrees, -100 degrees that the human can not live in there, Watt would not able to come back alive on the Earth. If you guys are left on the Mars alone, can you survive in there???

The Jeonju as the best example of geotourism

  Jeonju is one of the most popular attractions for not only Koreans but also foreigners. Actually, the number of tourists in Jeonju for a year is roughly 10 million which is 1/5 of the population of South Korea. Furthermore, according to the Lonly Planet which is the famous travel guide book, Jeonju is ranked third place in the ‘Best Asian Travel Destination’. The reason why many tourists started to visit Jeonju is the geotourlism conducted by Jeonju municipal government Through Jeonju discover two positive effects as a result of geotourlism.

 

  The first positive effect of geotourlism policy is that Jeonju was able to protect their own traditional culture such as heritage or food of the village. In the past, Under the 1910-1945 Japanese colonial rule, Japanese merchants flocked to the city to engage in rice transactions and settled inside the fortress. In response, residents of Jeonju built the about 700 Korea traditional houses called Hanok at the opposite of the Japanese complex, forming their own hanok village. Jeonju municipal government selected Hanok Village as a protection zone in 1977 to preserve the over devlopement and heritage of this town. Therefore, anyone can not damage the Hanok as well as establish a large building or apartment in this Village. Also, people tried to develop and specialize their soul food of Jeonju after enacting the policy prohibiting all of the foreign food sales. In the result, Jeonju became one of the most famous cities especially in traditional Korean food such as BIBIMBOB, TTEOKGALBI. Through geotourlism policy, Jeonju could protect their heritage, traditional food and also prevent over-development.

 

   A second positive effect of geotourlism policy is that Jeonju has provided jobs for local people through

the geotourlism policy. Because it is prohibited that the establishment and managing of accommodation such as motels and hotels within the Jeonju Hanok Village, tourists have to stay in Hanok rather than the famous resort or modern hotel. This policy becames an opportunity offering the local people the jobs running the traditional accommodation. In addition, Jeonju municipal government have made Youth Street called Chungnyunmall in order to provide the jobs for the young. It supported them to operate the unique store designed by themselves. For example, one young man developed special beverage which is filled in a bulb-shaped bottle, this cafe became famous through word of mouth. Consequently, this geotourlism policy attracted many tourists and the young people was able to earn a lot of money. In other words, the Youth Street called Chungnyunmall have boosted local economy through a variety of aritistic cafes and unique souvenir shops in Jeonju.

 

  Jeonju must maintain the geotourlism policy if they want to develop Jeonju as more popular tourist attraction. Otherwise, there will be built a lot of accommodation such as hotels and resorts in Jeonju. Finally, they would lose the traditional culture of Jeonju and also the local shops such as the unique souvenier shops and cafes in Youth Street called Chungnyunmall might be disappeared under the influence of franchise shop of large companies. It will cause the local people lose their job or prevent the possibility of making much money. To protect heritage, food and their jobs, Jeonju municipal government must continue to maintain geotourlism policy and oversee whether it is conducted properly or not. It would be helpful that Jeonju strenghten this policy to keep their policy and attract more tourists.

 

  The other attractions wherever want to conserve their traditional culture such as heritage, food or prevent to over-development they should carry out the geotourism policy like Jeonju. In addition, they would offer the local people a lot of jobs and chance to make money by prohibiting manage franchise shop of large companies. As the result, the geotourism policy enables to the attractions be distinguished from the antoher place and attract more tourists.
