This study is conducted to determine whether Chinese students currently attending Korean universities are satisfied with their university life and to identify the problems they are experiencing. A survey was conducted with the graduate students attending K University and 202 students participated in the study. According to the study, most students are very satisfied with Korean universities and would recommend them to their friends. Regardless of gender, degree program, or major, the most difficult aspect of school life is understanding and communicating in class due to language problems. Even students with high TOPIK scores experience difficulties in communication and comprehension during class. One of the most significant problems that Chinese students have is a lack of interaction with Korean students. They want to interact with Korean students through club and team activities at the university. They requested that the university provide international students with opportunities to participate in various programs, such as sports activities, to help overcome feelings of alienation and isolation. Based on the study results, suggestions to support Chinese students to adjust educational environments in Korea were presented.

This study was conducted to develop a screening method using Colilert-18 and a device for the detection of E. coli from agri-food production environments and fresh vegetables. The specificity and sensitivity of Colilert-18 by temperature ($37^{\circ}C$ and $44^{\circ}C$) were evaluated with 38 E. coli and 78 non-E. coli strains. The false-positive rate was 3.8% (3/78) and 0% (0/78) at $37^{\circ}C$ and $44^{\circ}C$, respectively. The detection limit of E. coli at $37^{\circ}C$ at <1.0 log CFU/250 ml was lower than that at $44^{\circ}C$. The efficiency of the developed device, which comprised an incubator equipped with a UV lamp to detect E. coli in the field, was evaluated by measuring the temperature and UV lamp brightness. The difference between the set temperature and actual temperature of the developed device was about $1.0^{\circ}C$. When applying the developed method and device to various samples, including utensils, gloves, irrigation water, seeds, and vegetables, there were no differences in detection rates of E. coli compared with the Korean Food Code method. For sanitary disposal of culture samples after experiments, the sterilization effect of sodium dichloroisocyanurate (NaDCC) tablets was assessed for use as a substitute for an autoclave. The addition of one tablet of NaDCC per 50 ml was sufficient to kill E. coli cultured in Colilert-18. These results show that the developed protocol and device can efficiently detect E. coli from agri-food production environments and vegetables.

Inflammatory and fibrotic responses are accelerated during the reperfusion period, and excessive fibrosis and inflammation contribute to cardiac malfunction. NecroX compounds have been shown to protect the liver and heart from ischemia-reperfusion injury. The aim of this study was to further define the role and mechanism of action of NecroX-5 in regulating inflammation and fibrosis responses in a model of hypoxia/reoxygenation (HR). We utilized HR-treated rat hearts and lipopolysaccharide (LPS)-treated H9C2 culture cells in the presence or absence of NecroX-5 ($10{\mu}mol/L$) treatment as experimental models. Addition of NecroX-5 significantly increased decorin (Dcn) expression levels in HR-treated hearts. In contrast, expression of transforming growth factor beta 1 ($TGF{\beta}1$) and Smad2 phosphorylation (pSmad2) was strongly attenuated in NecroX-5-treated hearts. In addition, significantly increased production of tumor necrosis factor alpha ($TNF{\alpha}$), $TGF{\beta}1$, and pSmad2, and markedly decreased Dcn expression levels, were observed in LPS-stimulated H9C2 cells. Interestingly, NecroX-5 supplementation effectively attenuated the increased expression levels of $TNF{\alpha}$, $TGF{\beta}1$, and pSmad2, as well as the decreased expression of Dcn. Thus, our data demonstrate potential antiinflammatory and anti-fibrotic effects of NecroX-5 against cardiac HR injuries via modulation of the $TNF{\alpha}/Dcn/TGF{\beta}1/Smad2$ pathway.

There are remains of Japanese gardens in Korea which were built during Japanese occupation in 1910-1945. However, systematic database has not been established for location, quantity, nor types of remaining gardens. This study is aimed at defining current status of Japanese gardens built in Korea. By categorizing types of remaining these Japanese gardens, we also aimed to build a systematic data base for Japanese gardens in Korea. This study was co-conducted by researchers from Korea and Japan. The team identified 17 Japanese gardens remaining in South Korea and categorized them into 4 groups; 1) Japanese garden built by Japanese in modern Japanese house in South Korea, 2) Japanese garden built by Korean in traditional Korean garden and 3) Garden built by Japanese in temples in Korea. (at request by Koreans). This categorization reveals information about the inflow of Japanese gardening culture into Korea and deserves to be an important part of modern gardening History. And the rest are 4) Japanese gardens built at Korean residence, but with much damage and alternation. In this paper, we present the findings to serve as preliminary data for defining Korean traditional gardens and for utilizing Japanese gardens in Korea as historical and cultural infrastructure.

The Khogno Khan mountain special protected area belongs to Khogno Khan subdistrict of Gurvanbulag district of Bulgan Province and is 46.9 sq.km. with its main feature being mountain forest zone. In this paper we present some results of research of the Anthropological and archaeological team of Mongolian Korean Joint research expeditions carryied out in Khogno Khan mountain special protected area from 27 July to 1 August, 2000. During archaeological reconnaissance we discovered around 27 localities of archaeological monuments belonging to different historical periods (from the Neolithic up to the Mongolian period, $13^{th}-17^{th}$ Century) in the territory of the Khogno Khan special protected area. Based on the results, we especially want to point out 1). The archaeological and historic monuments (from the Neolithic up to modern era) found in the Khogno Khan mountain and its surrounding area show that since the Neolithic period (around 8000 years ago) this area was occupied by the ancestors of Mongolians and it was used during subsequent historic periods on the one hand. 2). On the other hand the Khogno Khan mountain region was one area where there occurred intensive admixture between populations of Kurgan culture, Deerstone culture from the West Mongolia and the population of slab graves culture from Central and East Mongolia during Bronze and Early Iron Age. 3). Today the mountain is one of the area with a unique assemblage of archaeological monuments from different historic periods, what naturally seems like an open-air natural museum of Mongolian Prehistory.

Purpose: The Purpose of this study is to build up model of the emotional labor worker's health. Methods: Data was collected from 230 emotional labor workers from 2 department stores, 2 insurance companies, and 3 hotels located in Seoul and Kyung-gi areas, by the health managers and team leaders. For data analysis, descriptive statistics, pearson correlation, factor analysis and covariance structure analysis were used by SPSS window 10 version and AMOS 4.01. Results: The hypothetical model showed a goodness-of-fit to the empirical data(GFI=0.90, RMR=0.04, NFI= 0.79, PNFI=0.64). Eight out of fifteen paths of the model were accepted, while the other seven paths rejected. : From 'surface acting' to 'health', from 'social support' to 'surface acting', from 'social support' to 'health', from 'factors of organizational culture' to 'surface acting', from 'factors of organizational culture' to 'deep acting', from 'personal factor' to 'social support', from 'factors of organizational culture' to 'social support', from 'routine stress' to 'social support'. In conclusion, it has been confirmed that surface acting and social support were dominating factors to the health of emotional labor workers. Conclusion: In order to manage the health of emotional labor workers, it is imperative to develop a strategy to reduce their surface acting.
