BACKGROUND/OBJECTIVES: Proper nutrition intake during pregnancy and lactation is very important to both mothers and babies. Pregnant women should maintain proper nutritional status to restore decreased physical strength due to pregnancy and childbirth and produce breastmilk for the growth and development of the baby. Recently, the number of Chinese people living in Korea has increased as the exchange between Korea and China becomes active. It is important to provide proper nutrition education for pregnant women of both countries considering cultural differences. SUBJECTS/METHODS: The subjects of this study were postpartum women in Gyeonggi, South Korea and Jinhua, China. The subjects were 20-45 years old less than six months after childbirth. A survey, using self-administered questionnaires, was conducted from October 2018 to January 2019. For data analysis, 221 Korean postpartum women (KPW) and 221 Chinese postpartum women (CPW) questionnaires were used. RESULTS: KPW had significantly higher nutritional knowledge score and dietary attitude score than CPW (P < 0.001). However, overall score for dietary habits was significantly higher in CPW compared to KPW (P < 0.001). In KPW, nutritional knowledge (P < 0.01) and dietary attitude (P < 0.001) had significantly positive correlations with dietary habits. The proportions of KPW and CPW who answered that they had experience of nutrition education were 28.5% and 80.1% (P < 0.001). The score for dietary habits was lower as the hours for watching TV and using mobile phone became longer in postpartum women of both countries, with significant differences in KPW (P < 0.001) and CPW (P < 0.05). In KPW, the score for dietary habits in postpartum women with exercise experience was significantly higher than that in postpartum women without exercise experience (P < 0.001). CONCLUSIONS: More pregnancy-related nutrition education should be provided and various and effective nutrition education programs, which not only transfer information but can be practiced in the actual life, should be developed.

In case of tissue invading nematode, proteolytic enzyme was required at their parasitic life. Proteinases obtained from these parasites(Toxocara canis, Ansakis spp. and Trichinella spiralis) were extracted, isolated and further purified. And then the analysis for activity and inhibitory effect of proteinases were performed by appropriate substrate. Determination of protein as a circulating antigen was done in use of infected animal serum with above parasites, respectively. For above experimental objects, following procedures were performed. First, enzymatic activity was measured in use of azocasein and inhibitory effect of porteinase were studied by various inhibitors. Second, partially purified proteins containing enzymatic activity were obtained by ion exchange chromatography, ultrafiltration and electrophoretic elution. Third, role of the partially purified protein as a circulating antigen. The results obtained were as follows : 1. Enzymatic activity of each nematode proteinase was varied according to pH. Optimal pH of Toxocara canis, Ansakis spp. and Trichinella spiralis were pH 6.0, pH 5.5 and pH 6.5, respectively. The optimal molarity of buffer was 0.1M phosphate buffer. Although little difference between these proteinases was observed, temperature stability was at least maintained at $4^{\circ}C$ until 5 days. 2. In case of Ansakis spp. and Toxocara canis, enzymatic activity of these proteinases was considerably inhibited by Leupeptin and EDTA. For maximum enzymatic activity of above proteinases, it was required that cysteine residue of enzyme should be protected. And it was suggested that metallo type was contained in enzyme active site. Proteinase of Trichinella spiralis contained metallo type also. 3. Although partial purification was performed in Ansakis spp. and Toxocara canis, proteins maintaining enzymatic activity were identified as a circulating antigen. From SDS-PAGE and immunoblot, 25 kDa was presented in Ansakis spp.. Specific antigen of Toxocara cains was 110 kDa protein fraction. 55 and 42 kDa proteins were reacted with normal serum. Trichinella spiralis 60 kDa protein fraction was successfully purified from excretory materials in culture. As a result of immune-reaction with Trichinella spiralis infected serum, highly purified 60 kDa protein was maintained antigenicity until final purification step.

This study was conducted to check the cabin crew's safety perception in relation to the airline's safety climate and cabin crew's safety action and to verify that the safety perception's mediation effects. The results of the study confirmed that all three factors of the safety climate have a significant impact on safety perception, and among them, safety practice is the most significant. Accordingly, Airlines need to establish a community that enables real-time information exchange for air accidents so that the cabin crew can present real-time examples of safety-related accidents. In addition, it will be necessary to work with external safety agencies to form an active attitude for the establishment of safety procedures in order to prevent recurrence of safety problems while considering the causes of such incidents internally in the event of an airline safety accident. In addition, it was confirmed that safety training was the most significant factor to safety action, among which all three elements of the safety climate had a significant effect on safety action. Therefore, airlines need to expand practical training on aircraft to full-scale safety training to build an immediate resolution for cabin crews in the event of an air accident. In addition, safety training should be established to encourage collaboration among aviation safety-related personnel to participate in safety training together to address aviation safety from a diverse point of view. Safety perception was has a significant effect on safe action. Therefore, airlines should reinforce the airline's safety management system by checking the status of the cabin crew's safety perception extending the level of punishment to the scope of retirement or disqualification to establish a firm awareness of safety. Finally, the safety perception has demonstrated partial mediation effects in relation to the safety climate and safety action. Therefore, the airline needs to improve the duties of the cabin crew that interferes with cabin safety duties. In addition, airlines should utilize advertisements emphasizing that safety is first.

This thesis aims to analyze the political, social, and cultural activities of the Acehnese ethnic group living in Jakarta, Indonesia. Based on analysis, this thesis examines how their ethnicity and national identity have been formed and expressed. For this purpose, this study deals with Taman Iskandar Muda (hereinafter referred to as TIM), a group of Acehnese transmigrants living in Jakarta. The immigration of the Acehnese to Jakarta started in the 1950s and the number of Acehnese people living in Jakarta persently amounts to 100,000. TIM, which was organized by the first generational of immigrants, functions to group Acehnese immigrants of various generations and class. Forum Keprihatinan Untuk Aceh(hereinafter referred to as Forka), an organization designed to solve the political problems of TIM, undertook various activities to maintain the peace of Aceh as the representative of TIM. Through those activities, TIM and Forka were able to confirm the feeling of homogeneity among the Acehnese who were living in their hometown and also strengthen their identity within the organizations. However, the fact that TIM and Forka put their focus on humanitarian activities paradoxically shows the political limitations that they sustain. TIM and Forka take care not to make their humanitarian activities seem as if they intend to openly strengthen their Acehnese identity and deny their Indonesian one. These political characteristics of Forka's identity are commonly found in groups that practice long-distance nationalism, as transmigrants in diaspora circumstances do. In the organization of TIM, there exists the menasah, which is a space where discussions of the ethnicity and the nation are practiced. As it is the space for local exchange, menasah reveals the identity of TIM through educational/social activities and public services. Menasah functions as the public arena where people practice ethnic identity on the basis of national integration. As a minority ethnic group living in Jakarta and its neighborhood, they are accustomed to double and selective political activities, social activities, and cultural practices. In order to adapt themselves to the double circumstance that they are faced with, they should live extemporaneously, and this life may be the fate that minority ethnic and transmigrants should endure.

Purpose - The purpose of this study was to review and analyze EAJBE (The East Asian Journal of Business Economics) of EABEA (The East Asia Business Economics Association) and all of their published articles of 2013 to 2017 and to revise and update the existing publication standards and practices in order to improve the overall quality and reputation of EAJBE. Research design, data, and methodology - This paper applied an analytical approach, a case study method, to analyze and examine the published articles and the publication standards and practices of EAJBE (East Asian Journal of Business Economics) from their first publication. Results - The EAJBE has been issuing academic journals four times a year since its foundation. Although it is a journal based in Korea, overseas scholars publish articles steadily compared to other academic journals and the EAJBE raises the level of globalization. The level of internationalization of association's management and editorial members is also high, making the overall academic journal more cosmopolitan. Conclusions - Although the EABEA (The East Asia Business Economics Association) is a newly formed, the association is actively managing the academic community and making two major goals for the development of the academic journal. First, this journal is actively attracting overseas scholars, and is raising the level of internationalization. As an integrated academic conference is held with overseas scholars, they actively exchange with overseas scholars by contributing and publishing their papers. Second, it is seeking to establish national and international ties by publishing the papers of Korean scholars as well as abroad and holding academic contests regularly.

In this paper, we studied the consciousness of Fisheries high school students Through these kinds of works, this paper will focus on how to activate the Fisheries high school in Kyungbuk province. Primarily, research of the consciousness of people living in the fisheries community of the Kyungbuk coast has been engaged in fisheries. Secondly, research is done the consciousness of Fisheries high school students. Thirdly, research of consciousness of neighboring middle school teachers. Finally, searching for reform measures toward activating Fisheries high schools in the whole country. The conclusions of the study were as follows: First, the proper view of fisheries should be settled again. The understandings of basic knowledge about maritime affairs and fisheries in the stages of elementary schools and middle schools are needed. Secondly, in order to find a way out of the difficulties in fishering villages, governmental financial support has to be presente. from the view of fisher folks who are engaged in the fisheries. Thirdly, larger portions of economic value should be allocated to fisheries villages by improving fisheries structure of the fishery. Actually, lower incomes have burdened fisheries villagers with more debts. Fourthly, academic and care counseling must concentrate on the diversification of courses after graduation from fisheries high schools. Realistically, students of fisheries high schools are longing to enter into universities. Fifthly, reorganization of specialized highschool systems, changes of titles of schools and reconstruction of departments should be steadily carried out. Finally, high morale of fisheries highschool teachers should be revised using various steps. They didn't appear to be proud of their teaching jobs. Supervisors ought to exchange their opinions with teachers for the purpose of development of fisheries high schools.
