Although the number of foreign students is increasing with the development of internationalization, international students are often unfamiliar to the campus environment in the early stages of their school visits. This research aims to solve the problems of foreign students' unfamiliarity with the campus and the inconvenience of study and life after enrollment and to design and produce an AR campus guide application based on gamification. The application built are designed according to the targets, missions, and rewards of different places. Through the 'A Survey on the Awareness of Kongju University's Buildings' questionnaire survey of international students at National Kongju University, six place were selected as POI (Point of Interest). Missions and questions suitable for users were designed. Through this application, it is hoped that users can learn about important places of the school interestingly and learn about the use of related convenience facilities.

This study used Gauss-Poisson jump diffusion process on standard assets to estimate the statutory reserves of Variable Annuity (VA) guarantees specified in Korean bylaw of insurance supervision and calculated guarantee fees and risks based on the model to see the effect of considering the jumps. Financial assets, except KOSPI 200, have fat-tailed return distributions, which is an indirect evidence of discontinuous jumps. In the case of a domestic stock index and foreign stock indexes(Korean Won), guarantee fees and risks decrease when jumps are considered in models of underlying assets. This is explained by decreases in standard deviations after the jump diffusion is considered. On the other hand, in the case of domestic bond indexes and a foreign bond index(Korean Won), guarantee fees and risks tend to increase when jumps are considered. Results from a foreign stock index(US Dollar) and a foreign bond index(US Dollar) were opposite to those from the same kinds of Korean Won indexes. We conclude that VA guarantee fees and risks may be under or over estimated when jumps are not considered in models of underlying assets.

Foreign body in the esophagus is not uncommon in the otolaryngological field and esophageal perforation followed by mediastinitis is one of the most serious complications. Authors had experienced such case developed in 69 year old female patient. This woman swallowed a piece of sharp glass accidentally. Severe pain and swelling around the neck developed after ingestion. Marked subcutaneous emphysema was noted on first examination. By esophagoscopy, longitudinal laceration at right lateral wall of the cervical esophagus was noted and a lot of food debries were removed through this perforation, but foreign body could not be found. On third hospital day, patient complained chest pain and dyspnea. Mediastinal widening was noted on chest P-A. Tracheostomy was performed on next day and neck swelling decreased much. In spite of massive antibiotics, mediastinal abscess was developed and external drainage was performed on 15th hospital day. She was discharged on 38th hospital day with marked improvement and recovered completely on follow-up study. Still, we do not know where the foreign body is located.

The objective of this study is to uncover the standard and procedure of the review for the online game to export to China and try to find a plan how to solve a problem such as regulation for the online game imported into China depending on a protective policy for homemade game. The literatures related to the policy of China online game industry and the present condition of the wholistic restriction are reviewed and the standard and procedure of the review of China online game which is veiled was able to find definitely by using the case study on Korean company which was a great success as localization in China. As a result of this study, we found that the key factor on the review standard of China online game is the anti-social personality, such as 'the overthrow of Chinese socialist system', 'the territorial issue as the eviction of Hong Kong or the acknowledgment of Taiwan government', 'independence problem of the minorities', and 'damage to property as national treasure', et cetera. While the review of the homemade game in China takes about a month through just two steps in review process on online game, that of foreign game is required over at least three months through four steps in it. Moreover, it is difficult for foreign games to obtain the license due to total amount regulation for online game by 'General Administration of Press and Publication of the People's the Republic of China'. In the case of the joint-venture company, it is most important to the smooth communication between Korean company and Chinese company in order to overcome these strong regulation for online game review in China. Furthermore, as Chinese company in outward appearance it is need to be positioned absolutely in Chinese marketplace. The definite positioning strategy enables foreign companies to avoid the strong regulation about the foreign game in China. To understand, finally, deeply politics, society, and culture presented in Chinese ethics textbook permits the foreign companies to predict the exact standard of the review for online game. Therefore, this study is concluded with key implications to sustain guidelines on the deliberation for foreign companies which want to export online game to China to improve the predictability and accountableness about the review of the online game in China.

This study investigates the causal relationship between stock prices and exchange rates for six Middle Eastern countries, namely, Egypt, Iran, Jordan, Kuwait, Oman, and Saudi Arabia before and during (after) the 2007 global financial crisis for the period between January 2004 and September 2015. The sample is divided into two sub-periods, that is, the period from January 1, 2004 to September 30, 2007 and the period from October 1, 2007 to September 30, 2015, to represent the pre-crisis period and the post-crisis period, respectively. Using Vector Autoregressive (VAR) model in a multivariate framework (including two control variables, inflation rates and oil prices) the results suggest that in the case of Jordan, Kuwait and Saudi Arabia, there exists bidirectional causalities after the crisis period but not the before. The opposite status is available for the case of Iran. In the case of Oman, there is bidirectional causality between the variables of interest in both periods. The results also reveal that the relationship between stock prices and exchange rates has become stronger after the 2007 global financial crisis. Overall, the results of this study indicate that fluctuations in foreign exchange markets can significantly affect stock markets in the Middle East.

Hydrocarbon fires and explosions in petrochemical plants have occurred repeatedly every year. But domestic law of fire protection system is insufficient for the worst case scenario. In this study, we analyzed domestic and foreign standards of fire protection system in petrochemical plants and surveyed firefighting equipment of 32 petrochemical plants in ulsan petrochemical complex. Finally, it is necessary to design fire water supply based on the worst case scenario in petrochemical plants and firefighting equipment such as fixed water spray system, elevated monitor nozzle, water curtain, large amount foam monitor system should be installed for the worst case scenario in petrochemical plants.

Today's universities have a keen interest in educational reform. The issue of population decline in college-age due to population decline is not new. Universities have been developing quantitatively for a long time and are now considering ways to survive rather than qualitative growth. Since the sharp decline in the school-age population due to the population decline has no clear solution immediately, universities are overcoming this crisis by creating many alternatives. Attracting international students is one of them. In this study, the effectiveness of photovoice was examined through the analysis of the case of the Korean-Japanese convergence cartoon class. The photo-voice method has sufficient potential as a teaching method for foreign convergence classes and can be expected to play a role as a teaching method suitable for students participating in convergence classes with different social, cultural, and linguistic backgrounds. In particular, in the convergence class, since participating students generate research materials through photo production, it can be a tool for inner exploration necessary for webtoon production and a tool for narrative inquiry for storytelling. It is expected that expanding the understanding and use of photo voice will have the methodological value of convergence classes. In addition, the teaching method using photo voice produced in the composition of photos and stories is likely to be used as an appropriate tool for convergence classes for students with different social, cultural, and linguistic backgrounds.

Republic of Korea had undergone a meaningful transformation from aid recipient country to aid donor country and it was the only case among OECD countries. It became the 24th member of DAC in November, 2009. Therefore, it is required that we have to expand assistance which comes up to current economic power of Republic of Korea. However there are weak theoretical consideration about the obligation and justification of foreign aid fundamentally. These researches are almost about communitarianistic, liberalistic perspectives of view but with these, it is hard to enlarge current foreign aid into international level and it also takes a passive approach in obligation to provide. With these contexts in mind, this study proposes cosmotolitanism as an new alternative of foreign aid. This paper seeks to discuss that why we should give assistance to poverty-stricken counties and checking whether we have a obligation of foreign aid or not and the way or the extent to deal with if there is a obligation to help. Cosmotolitanism suggests that whole world is obliged with helping each other to enjoy equal rights and meet the obligation for others because people of the third world countries also have their own lives on the Earth like us and they are sharing all-global plan and future together. The existing discussion took a negative, restrictive attitude but it could mention that there is great relevance to discuss about Cosmotolitanism since it connotes the obligation for the third countries and their people itself.

This study compared and analyzed the characteristics of new words by classifying 197 newly coined Korean and Chinese characters in 2017 and 2018 into single, compound, derivative, abbreviated, and hybrid words according to the coined method. In the case of a single language, Korean is all words borrowed from Chinese and English. However, no monolingual language appeared in Chinese. In the case of compound words, the format of the Chinese synthesis method was much more diverse and the generative power was stronger than that of Korea. In the case of derivatives, there are not many prefixes in both countries, and Korean suffixes have the strongest productivity of Chinese suffixes and weak productivity of foreign and native suffixes. Korean foreign language suffixes were characterized by relatively more appearance than Chinese. In the case of abbreviations, it can be seen that the productivity of dark syllables is stronger for Korean abbreviations, and the productivity of empty syllables is stronger for Chinese abbreviations. In the case of mixed languages, the hybrid form of Korean was much more diverse than that of Chinese. Through this study, it will be possible to help Chinese Korean learners understand the process of forming a new language, and to develop their ability to guess the meaning of Korean words while learning a new language.

Climate changes and environmental pollution problems are continuing every year. In Korea, the carbon dioxide(CO2) emissions by the transport sector reached around 20% of pollution. Many countries are enforcing the pollution-control policy. Korean government has introduced the modal shift grants as well as in other countries. In case of nation's transportation plan, the policy basis of green distribution is emphasized. However, the shipper and logistics company have low interests in the modal shift as the massive transportation system. The purpose of this paper is that I studied the policy alternatives for the modal shift of foreign railways., And also I studied the difficult problems at altering the railway freight from domestic road freight and I suggested the alternatives of modal shift to solve those problems.
