The Republic of Korea is rapidly entering an aging society. With the aging of society, the overseas travel of the elderly is increasing rapidly. According to the Korea Tourism Organization, the number of overseas tourists aged 61 or older last year exceeded 2.5 million, of which over 80 were over 200,000. Age is no longer a limiting factor for traveling abroad, but traveling to unfamiliar places is certainly a challenge. Old people may experience a variety of problems, so special care should be taken. In particular, the aircraft cabin environment is different from the ground, so elderly travelers with respiratory or heart disease require special attention. In this paper, we want to know the precautions and how to prepare for the safe air travel for the elderly.

The purpose of this study was to systematically review published articles on Yaksun studies and provide understanding on current and future studies with Yaksun and medical treatment with food. We performed systematic review on the Yaksun studies published recent 16 years from 2000 to 2016 using seven Korean database on research articles. We found 90 articles are relevant for the analysis. The articles on Yaksun were significantly increased since 2005. As for the research field, Food Science (39 articles, 31.0%) and Tourism (20 articles, 15.9%) were dominant throughout the years. Researchers from Science of cookery (35 articles, 35.0%) and Food and Nutrition (32 articles, 32.0%) were found to be most frequent. The prime type of research on Yaksun were the We found that the Survey (49 articles, 52.7%) was the most frequent research method and basic research for providing related data (41 articles, 45.6%) was easily found as for the purpose of the article. We found that there were insufficient reports on clinical efficacy of Yaksun, especially with the treatment of diseases. The interest of medical professionals is needed for the better understanding on the medical use of Yaksun and therapeutic diet which has potentials for integrative medicine.

The study began in recent years with the aim of grasping the nation's medical status following the fast-growing trend of international medical tourism and attracting foreign patients, among other things, Busan, which ranks second in attracting foreign patients after the nation's capital, Seoul, has been highly active in the past eight years, with foreign patients rising by about 426 percent, and Russian patients entering the sea. In addition, Gimhae and Changwon, the Busan-based Gyeongsangnam-do region, ranked first and second in number of foreign residents, and are inhabited by a variety of foreign workers. Medical institutions, such as hospitals, should be able to find directions within hospitals. It is also a space where information in various languages, including Korean, English, Chinese, or Russian, must be delivered in a single medium. Based on this research, the purpose of this research is to provide converged information that helps foreigners who are not familiar with Korean language easily understand the proposed recognition system when visiting hospitals. Therefore, this paper is applied to a multi-language survey of six medical institutions (A, B, C, D, E, F) at the university hospital in Busan, and 10 medical institutions (R, J) in Gimhae, South Gyeongsang Province with high foreign residents. Research results and contents are as follows. First, the results of analyzing the design of the sinusoidal system show that the font uses colorless Gothic fonts, arrows, and pictograms to introduce the design of a typical hospital sign system. Second, the results of the multi-lingual situation were found to have only two languages in the system, such as Korean and English, and to have four languages, including Korean, English, Chinese, and Russian, according to their geographical location. However, it was judged that most medical institutions currently have only two languages (Korean, English) that may cause some discomfort in terms of language for foreign patients in non-English speaking countries. Based on these findings, it is necessary to propose designs that are considered by Koreans as well as foreign users in the use of multilingual hospital sign systems.

This study was conducted to evaluate the neuroprotective effects of Cheonggukjang extract in in-vitro and in-vivo models. T98G-human glioblastoma cells were pretreated with various concentrations (1~10 mg/mL) of Cheonggukjang extract for 24 h and then exposed to $H_2O_2$ (1 mM) for 3 h. The neuroprotective effects of Cheonggukjang extract were measured using a CCK-8 kit assay, total antioxidant capacity (TAC) assay, reactive oxygen species (ROS) assay, and lactate dehydrogenase (LDH) release assay. The early stage focal ischemia rodent model was used as the in-vivo neurotoxicity model. Various concentrations (10~200 mg) of Cheonggukjang extract were administered to the animal models for 1 week. Peripheral blood was analyzed for glutathione peroxidase (GPx) expression by ELISA, and infarct volume reduction was analyzed by TTC staining. Cheonggukjang extract significantly (p<0.05) increased cell viability in T98G cells against $H_2O_2$ as well as against the induced neurotoxicity. Indeed, treatment with the Cheonggukjang extract induced a decrease in ROS and LDH expression and increased TAC significantly (p<0.05). However, Cheonggukjang extract did not induce a decrease in infarct volume or an increase in GPx expression in the in-vivo model. Despite the limitation in neuroprotection, Cheonggukjang extract may be useful for treating ROS injury.

BACKGROUND/OBJECTIVES: This study compared the perception of customers from Korea and the U.S. on the attributes of different formats of menu labeling The specific objectives were 1) to compare the customers' perceived usefulness, ease-of-understanding, clarity, and attractiveness of different formats of menu labeling between Korea and the U.S.; and 2) to compare the customers' use intention to different formats of menu labeling between Korea and the U.S. SUBJECTS/METHODS: A survey was conducted in Korea and the U.S. The participants were allocated randomly to view 1 of the 7 restaurant menus that varied according to the following types of menu labeling formats: (type 1) kcal format, (type 2) traffic-light format, (type 3) percent daily intake (%DI) format, (type 4) kcal + traffic-light format, (type 5) kcal + %DI format, (type 6) traffic-light + %DI format, and (type 7) kcal + traffic-light + %DI format. A total of 279 Koreans and 347 Americans were entered in the analysis. An independent t-test and 1-way analysis of variance were performed. RESULTS: Koreans rated type 4 format (kcal + traffic light) the highest for usefulness and attractiveness. In contrast, Americans rated type 7 (kcal + traffic light + %DI) the highest for usefulness, ease-of-understanding, attractiveness, and clarity. Significant differences were found in the customers' perceived attributes to menu labeling between Korea and the U.S. Americans perceived higher for all the 4 attributes of menu labeling than Koreans. CONCLUSIONS: The study is unique in identifying the differences in the attributes of different formats of menu labeling between Korea and the U.S. Americans rated the most complicated type of menu labeling as the highest perception for the attributes, and showed a higher use intention of menu labeling than Koreans. This study contributes to academia and industry for practicing menu labeling in different countries using different formats.

The volume of transfer passengers now faces a crisis because the number of Chinese and Japanese passengers, the majority of transfer through Korea, is decreasing. This paper is analyzing the their air travel behaviors as well as characteristics of their transfer behaviors at airport. According to the research, it is suggested that transfer passengers perceive the importance of duty-free stores but their satisfaction of using duty-free stores during their transfer at Icheon airport was proven to be low. Considering the characteristics of transfer service quality at Incheon airport, waiting time of transfer is important but not satisfactory for them. Moreover, information of free transfer tour to city downtown and paid-in transfer tour for medical tourism is not known very well among North East Asian passengers. Thus, it is necessary to do detailed research of North East Asian transfer passengers, who have transferred through Incheon airport more than twice a year, to find out their exact needs of transfer tour in Korea.
