The movie costume's function and the role can be defined by reflection of the society and the times, character portrayal, conveyance of image, and creation of fashion. Korean movie costumes have been differentiated from 1950s till 1990s in time period and the results of comparison between the times as follow : Movie and fashion hold same period in common so that sense of fashion is naturally contained in the movie costume. Therefore, excluding special movie that costumes are selected by designer, such kind of trend is notable in the times when costumes mostly selected by actors themselves. Most movie costumes are not designed after predicting up coming fashion by considering movie producing time so that notation between current fashion and fashion in the movie and mostly we see about one year behind fashion style. For FAD, fashion that quickly passes in each season can use costumes in fashion, considering movie producing time and time background, that it lack of trend of fashion in the movie. Korean movie industry lack of having perception of people who are in charge of taking care of movie so that costumes are not properly taken care of and uses only 5% of total movie producing cost. Such that kind having lack of preception and treatment of movie costumes can't expect development of movie costumes.

Objectives: The aim of this study is to examine the possible changes over the past ten years in the estimated daily dietary lead intake (Pb-D) stemming from the variation of daily intake amounts for each food group. The following factors were considered; 1. time trends in Pb-D as the estimated values, 2. the time trend in Pb-D by food groups 3. the most influential food groups for dietary Pb intake. Methods: Estimated Pb-D was drawn from food consumption according to food groups reported in the Korean National Health and Nutrition Survey and the lead contents of each food group as reported in 23 prior publications. Results: The estimated Pb-D in a 2009 survey was 40.8 ${\mu}g/day$, of which 22.5 ${\mu}g/day$ (55.1%) was of plant origin and 18.3 ${\mu}g/day$ (44.9%) was of animal origin. Meats and poultry, fish and shellfish among foods of animal origin and beverages of plant origin had the largest contribution in Pb-D among the food groups. Conclusion: Over past ten years, daily lead intakes have slightly increased among men. Otherwise, no clear variation is apparent among women.

본 연구에서는 한국과 미국의 대표적인 거래소인 빗썸과 코인베이스의 비트코인 가격을 ARIMA와 순환 신경망(Recurrent Neural Network)을 이용해 예측하고, 이후 각 국가의 뉴스 기사를 이용해 분리 학습에 기반한 separated RNN 모형을 제안한다. separated RNN 모형은 학습 데이터를 가격의 추세 변화 점을 기준으로 분리해 학습시킨 후, 추세 변화점 별 뉴스 데이터를 활용해 용어 기반 사전을 구축한다. 이후 용어 기반 사전과 평가 데이터 기간의 뉴스 데이터를 이용해 예측할 데이터의 가격 추세 변화 점을 찾아낸 후, 매칭되는 모형을 적용해 예측 결과를 산출한다. 2017년 5월 22일부터 2020년 9월 16일까지의 가격 데이터를 사용해 분석한 결과, 제안된 separated RNN을 이용해 예측한 결과가 한국과 미국의 비트코인 가격 예측 모두에서 순환 신경망(RNN)을 이용해 예측한 결과보다 높은 예측 성과를 보였다. 본 연구는 시계열 예측 기법의 한계를 뉴스 데이터를 이용한 추세 변화 점 탐색을 통해 극복할 수 있고, 성과 향상을 위한 추후 다양한 시계열 예측 기법 및 추세 변화 점 탐색을 위한 다양한 텍스트 마이닝 기법을 적용해볼 필요가 있음을 시사한다.

This study attempted to assess the durability of the trend in increasing childcare time and to get some clues based on research findings to make efficient policy interventions in case there is a need to continue or reverse course for such trend. In doing so, a total of 9,668 diaries from the 2004, 2009, and 2014 Korean Time Use Survey were analyzed targeting parents with a preschooler as their eldest child. Parental time was regressed on parents' weekly work hours, mother's relative income, parents' education and gender role attitudes. Furthermore, increase in parental childcare time was decomposed into parts that were attributable to differences in the means and slopes of associated factors. Analytic results revealed that; parents' weekly work hours were associated with time spent on childcare from 2004 to 2014; the negative relationship between mother's relative earnings and her childcare time in 2004 and 2009 was reversed to a positive one in 2014; parent's education had stronger positive effects on father's than on mother's childcare time; parents' gender role attitudes had a weak association with childcare time; social and cultural changes such as decrease in work hours, higher education, more egalitarian gender role attitudes, and rise in women's wages contributed to the increase in parental childcare time, but in a different way for mothers and fathers. By taking into account the social and cultural context behind the changes, this study is able to provide a more constructive implications for childcare policy in Korea.

Data are limited on the association between dietary patterns and screen time among Korean adolescents. The present study identified dietary patterns of 691 adolescents, aged 13-18 years, who had participated in the Third Korean National Health and Nutrition Examination Survey (KNHANES III) and analyzed their associations with screen time. Screen time was defined as the time spent watching TV, using a computer, or playing video games was calculated as a sum of all these times. Dietary patterns and their factor scores were derived from a food frequency questionnaire using the factor analysis method. To analyze the association between dietary patterns and screen time, we conducted multiple linear regression analysis. We also performed multiple logistic regression analysis to estimate odds ratios (OR) of excessive screen time (2 hours or longer per day) and 95% confidence intervals (CI). We identified 2 dietary patterns labeled "the Korean healthy dietary pattern" and "the Western diet and fast foods pattern". The former included mixed grains, legumes, potatoes, red meat, eggs, fish, dairy products, fruits, vegetables, seaweeds, and mushrooms, whereas the latter included noodles, bread, red meat, poultry, fast foods, snack, and soft drinks. After controlling for potential confounding factors, factor scores for the Korean healthy dietary pattern were inversely associated (P-value for trend < 0.01) and those for the Western diet and fast foods pattern were positively associated with the screen time (P-value for trend < 0.01). Adolescents in the top tertile of the scores for the Korean healthy dietary pattern had a multivariable-adjusted OR [95% CI] of 0.44 (0.25-0.75) for excessive screen time compared with those in the lowest tertile. On the basis of these findings, adolescents who have excessive screen time may need to be encouraged to consume a more healthy diet.

Many scientists today say that converged technologies, not specifically dedicated technologies, will be in the vanguard in the $21^{st}$ century. Technological Convergence is the merging of different areas of technology to perform similar tasks. Since we are living in the era of Technological Convergence, it is time for us to think about how to cope with the daily demands we are facing in science parks. Technological Convergence is a mega trend in commercial areas today but, so far, no science parks seem to have tried to reshape their management policies or programs in order to utilize this trend. For the development of science parks we suggest some tasks such as: identify potentials for Technological Convergence, establish a convergent ecosystem by building connections across stove-piped systems, effect a technological convergence platform, and conduct further research for strengthening plans for converging technologies.

본 연구는 한국노동패널 최근 자료를 사용하여 우리나라의 세대 간 임금 소득이동성을 추정하였다. 선행연구의 짧은 패널 기간과 적은 표본 수의 문제 등을 보완하였다. 세대 간 장기임금소득탄력성은 0.3 근방으로 추정되어 문헌에서 보고된 다른 나라들의 추정치들에 비해 낮아 소득이동성이 상대적으로 큰 것으로 분석되었다. 2006년 이후 자료로 추정한 세대 간 소득이동성들의 추세가 2005년을 기준으로 한 선행연구에 비해 낮아지고 있는 것으로 나타나 최근의 글로벌 경제위기로 소득이동성이 저하되는 추세가 있을 수 있음을 시사하고 있다.

The 5G system standardization body has been developing standard functions to provide ultra-high speed, ultra-high reliability, ultra-low latency, and ultra-connected services. In 3GPP Rel-16, which was recently completed, this system has begun to develop ultra-high reliability and ultra-low latency communication functions to support the vertical industry. It is expected that the trend in the adoption of mobile communication by the vertical industry will continue with the introduction of 5G. In this paper, we present the industrial Internet-of-Things (IIoT) service scenarios and requirements for the adoption of 5G systems by the vertical industry and the related standardization trend at present. In particular, we introduce the 5G time-sensitive networking standard technology, a core technology for realizing 5G-based smart factories, for IIoT services.

Recent changes in the coastal sea surface temperatures (SST) in Korea are studied by time series analysis of daily SST data during the last 60 years (1936-1995) at 18 coastal observation stations of the National Fisheries Research and Development Institute. The climate of coastal SST in Korea are rapidly changing in recent years. General trends of coast SST changes in Korea are as follows. The annual averages of SST are increasing. The annual ranges of SST variation are decreasing. The winter SST are increasing while the summer SST have a decreasing tendency. Climatic changes in coastal SST in recent 30 years (1965-1995) are more pronounced than those in the last 60 years (1936-1995). The observed trend of coast SST implies that the climate in Korea shows a tendency to shift from temperate zone to subtropical zone.
