The purpose of this study was to analyze the trends in domestic and international gifted education in the last six years (2010-2015) by utilizing social network analysis methods. For papers of gifted education in Korea, two KCI (Korea Citation Index) rated journals, the 'Gifted/Talented Education' (The Korean Society for the Gifted) and 'Gifted and Talented Education' (The Korean Society for the Gifted and Talented Education) were selected and 457 pieces published in two journals were collected. The papers of 347 published in SSCI rated journals, 'The Gifted Child Quarterly,' 'Journal for the Education of the Gifted,' and 'High Ability Studies' were selected. English keywords were extracted from 457 papers from Korean journals and 347 papers from foreign journals and the Social Network Analysis (SNA) way was utilized for keyword frequency and central network analyses. It was appeared that the trends of paper keywords from domestic and foreign countries showed common keywords, 'academically gifted', 'science gifted', and 'gifted' as center keyword frequency, and keywords, 'achievement', 'identification', 'intelligence' appeared as the most frequent ones. For domestic papers, keywords, 'creativity', 'gifted education', and 'gifted education teacher' were the highest frequent keywords while keywords, 'foreign countries', and 'student attitudes' were most frequent ones for the foreign countries. For the analysis of papers from five journals as one group, it was found that keywords, 'identification', 'intelligence', and 'achievement' were the most important common ones and keywords, 'cognitive', 'motivation', and 'self-concept' were appeared as important keywords. The trend of gifted education in Korea seems to be different from ones of foreign countries, domestic papers of gifted education rarely included keywords of 'foreign examples', 'student attitudes', and 'gender differences.' Consequently, the trend of gifted education in Korea called for various research perspectives.

This study is to investigate the trend of researches on food and culture from 1990 to 2003. With a literary approach, this paper analyzes how many papers were published and what was the major research subject. We classified the journals published during this time into 10 different categories and we are to grasp a research trend. 1) Historical approach on the traditional food and food habit; 2) Globalization of Koran food; 3) Use and preparation for traditional food; 4) Table setting and table manner; 5) Provincial cuisine; 6) Traditional festive food or celebratory meal; 7) Religious food; 8) Fusion food; 9) Food and culture in foreign countries and food habit of Korean people living abroad; 10) Studies related with satins out. It was revealed that 268 papers(=ps) were published. Eating out was the most frequently reported subject(100 ps), followed by provincial cuisine(54 ps), use and preparation for traditional food(49 ps), food habit for foreign people and Korean people living abroad(22 ps). Researches on these 4 topics have been accelerated since the late half of 1990s. This reflects the social factors such as rapid growth of food service industry, settlement of local autonomy, popularization of leisure activities and accelerated introduction of foreign food and culture. Half of the studies on the eating out dealt with eating out behavior. And 30 papers were reports on the food service industry situations. More than half of the studies on the provincial cuisine(26 ps) were concentrated on digging out recipes. Studies on the use and preparation for traditional food were mainly about what kind of food and how often the food is used(17 ps). Kimchi was the most frequently studied food. There were 11 papers regarding food and culture in foreign countries. Most of the authors were historians or linguists. Food habit of Korean people living abroad were investigated in 7 papers. There was few studies on fusion food, table setting and table manner. This doesn't meet with increasing demand for specialized information in then fields. Researches on the traditional festive food or celebratory meal(5 ps) and religious food(9 ps) were negligible. Papers on the historical approach to the traditional food and food habit were limited(12 ps). Moreover, most of them were patchwork of existing literatures. Continuous researches to exploit the historical facts based on literary proof should be tried with patience. Otherwise, the papers will copy the hackneyed knowledge repeatedly. Globalization of Korean food means the development of Korean food for foreign people and export of them worldwide. Only 16 papers were reported on this subject, 14 of them were published after 2000, 8 of them were surveys on the foreigners' food preference. In order to get practical informations on what we develope and how we sell for the foreign customers, profound research on their food habit should be done.

It seems that the \"fuzzy boom\" which began with its applications has calmed down and fallen into decay at least in Korea. But many foreign researchers say the research related to fuzzy theory has been only running its right course. In this paper, we discuss the trend and direction of reaserch related to fuzzy theory. The search trend is obtained through the analysis of the papers of the latest 10years papers in the journals of three societies: KFIS, SOFT and IFSA.

In recent years, international migration of professional workers is significantly increasing as globalization has been deepened more and more. South Korea is not an exception for this case. Immigration of professional workers have steadily increased since 2000 in Korea, and the number reached approximately to 50,000 in 2009. In addition, it is a major trend that immigrants of short-sojourn are decreasing and ones of long-sojourn increasing. Our research shows that foreign language instructor has the greatest number of foreign professional immigrants. The next is professional immigrants related to business-activities. There are considerably entertainers, but they have greatly decreased since 2003. Majority of foreign professional immigrants settle down in a few metropolises. Especially, they reside in Seoul Metropolitan Area and Southeast coastal region. Professional immigrants trend to do with Korean on the base of their offices rather than residental communities in terms of adaptation, and they do not have strong will to reside permanently in Korea. Moreover, they are located at a blind spot of Korean government's foreign immigrant policy, comparing to foreign workers and female marriage immigrants.

본 연구는 코로나-19 이후로 미지의 질병과 맞닥뜨렸을 때의 소비 경향에 중요한 영향을 끼치는 요소를 데이터베이스화하여 다각적인 방면에서 분석하고 성향 측정방법을 제시하였다. 포스트 코로나 시대는 디지털 혁명이 일어난 후 경제활동에 참여하고 있는 사람들 중 그 누구도 피해갈 수 없는 흐름이다. 또한, 소비의 흐름에 있어서 모바일을 통한 배달이 주류가 될 것이라는 것은 누구든 손쉽게 알 수 있을 것이다. 후에 제2의 포스트 코로나 이후 방대하고 구체적인 데이터를 사용하여 똑같은 방법으로 재분석 한다면 기업의 입장에서 발 빠른 대응으로 경제 침체 속의 호황을 맞이할 수 있을 것이라 기대된다.

In recent years, firm performance has been a topic that attracts many researchers. It is extremely important to identify the factors that change firm performance. In the current trend of competition and integration, foreign ownership, product market competition is found to reduce agency costs and impact firm performance. The purpose of this research is to investigate the relationship between foreign ownership, product market competition, and firm performance. Our research using a quantile regression model, through panel data of 290 companies listed on the Vietnam stock exchange (include Ho Chi Minh and Hanoi stock exchanges) from 2017 to 2019 that was collected by Thomson - Reuters DataStream has shown that foreign ownership and product market competition have a positive impact on Tobin's Q but are not statistically significant with ROA. Critically, our quantile regression results suppose foreign ownership, product market competition have a significantly larger positive impact in high-performing firms relative to low-performing firms. The results help propose solutions to planners and managers to change foreign ownership and product market competition to increase business performance. Besides, through quantile regression analysis, managers need to pay attention to the impact on foreign ownership, product market competition; there will be a difference between high-performing firms relative to low-performing firms.
