The purpose of this study is to examine the effect of contact with the elderly in a daily life on children's ageist attitude. Acknowledging the people's tendency to report in socially appropriate ways to the explicit attitude measurement, implicit measurement is introduced, and relation with the daily contact with elderly(DCE) is analyzed. The research question are as follows: 1) Are these two attitudes explained by different factors? 2) Can DCE alleviate both children's implicit and explicit ageist attitude? 3) How do the contact with grandparent and neighboring elderly affect the children's explicit and implicit ageist attitude? Data was collected from 503 fourth to sixth grade elementary school children. Child-Age Implict Association Test is used to measure implicit ageist attitude. Multinominal logistic analysis and ordered logistic analysis was applied. Followings are the main results: First, explicit and implicit ageist attitudes are found to be related with different predictors. Second, Elderly contact seems to lighten children's ageist attitude overall. Third, the effects of grandparental contact and the neighboring elderly contact on two different ageism were different. While the effect of elderly neighbor contact is limited to the expression of ageism, grandparental contact has a influence not only on the explicit but also on the implicit ageism, even though the effect on implicit attitude is limited in extent. Forth, not the quality of contact but the quantity of it was related to implicit ageist attitude. This result contradicts conventional idea of Intergroup Contact Theory. In the further research, the predictor of implicit ageist attitude need to be throughly examined.

The purpose of this study was to analyze the problem solving strategies of ordinary students, gifted students, pre-service teachers, and in-service teachers with the 'chicken and pig problem,' which has multiple strategies to obtain the solution. For this study, 98 students in the 6th grade elementary schools, 96 gifted students in a gifted institution, 72 pre-service teachers, and 60 in-service teachers were selected. The researcher presented the "chicken and pig" problem and requested them the solution strategies as many as possible for 30 minutes in a free atmosphere. As a result of the study, the gifted students used relatively various and efficient strategies compared to the ordinary students, and there was a difference in the most used strategies among the groups. In addition, the percentage of respondents who suggested four or more strategies was 1% for the ordinary students, 54% for the gifted students, 42% for the pre-service teachers, and 43% for the in-service teachers. As suggestions, the researcher asserted that various kinds of high-quality mathematical problems and solving experiences should be provided to students and teachers and have students develop multi-strategy problems. As a follow-up study, the researcher suggested that multi-strategy mathematical problems should be applied to classroom teaching in a collaborative learning environment and reflected them in teacher training program.

This study was conducted for the purpose of examining the Outstanding Universal Value, World Heritage Values, in Suzhou classical gardens and the operational method of the protection management of historic gardens, and the results of the study are as follows; The first, as a world heritage, Suzhou gardens proved OUV by showing the taste and lifestyle of the literati, the unique class of Chinese history, to the natural environment of the East Yangtze Delta region. In addition, it showed the exchange of international culture with unique Chinese garden techniques. Second, a authentic reconstruction of garden have original value because it exist records of the near past. The 20th-century archives described by the contemporary language and describing the heritage through images using such media as photography and drawing played a decisive role in restoring gardens. Third, the protection management of Suzhou gardens, which began in the 1950s, was carried out in detail, including the reconstruction of components such as buildings, the restoration of plant materials and horticulture technique, the creation of a list through the records of trees, the maintenance of props such as plaque, furniture, and the project to improve water quality and restore waterscape. The last, after the World Heritage inscribing, Garden's protection management was proceeded in two directions. One is that through the reorganization of the administrative management system and the enactment of laws related to Suzhou classical Gardens, the listing heritage is strictly protected and managed, and the other is that the historical gardens are used to establish urban masterplan and urban identity in Suzhou. The range of garden properties greatly expanded by distinguishing the principle of conservation from protection to rational use and the grade of protection, such as whole protection, maintenance protection and protection of historical sites.

Hanwoo has improved the quality of carcass traits. Especially, the higher the grade, the better the texture and taste of Hanwoo. One of the many factors that determine consumer preferences in food is the flavor. The flavor of food is expressed through heat treatment, and fat, carbohydrate and water-soluble compound are important ingredients for flavor. Therefore, The purpose of this study was to investigate the characteristics of fatty acids and carcass traits of 373 Hanwoos. The oleic acid (C18:1) and linolenic acid (C18:3) contents were 48.08% and 0.11%, respectively, while the carcass weight, Eye muscle area, back fat thickness and marbling score of the carcass trait were 383.73 kg, 83.88 ㎠, 10.91 mm, 3.89, respectively. The heritability of oleic acid was estimated to be 0.726, and the phenotypic correlation between eye muscle area and marbling score was estimated to be 0.105 and 0.141, respectively. The phenotype of the marbling score and eye muscle area were positively correlated with Oleic acid. Therefore, the improvement of these two traits seems to affect the increase of unsaturated fatty acid content.

In this study, a novel antiviral coating method for the air filtration system of subway station was investigated. Using dry aerosol coating process, we developed a high-performance antiviral air filter with spark discharger and carbon brush type ionizer. Silver nanoparticles were produced by a spark discharge generation system with ion injection system and were used as antiviral agents coated onto a medium grade air filter. The pressure drop, filtration efficiency, and antiviral ability of the filter against aerosolized MS2 virus particles as a surrogate of SARS-CoV-2 virus were tested with dust contamination. Dust contamination caused the increase of the filtration efficiency and pressure drop, while the antiviral agents (in this study, silver nanoparticles) coating did not have any significant effect on the filtration efficiency and pressure drop. Using these properties, we suggested a novel method to maximize the antiviral performance of the antiviral air filter that was contaminated by dust particles. Moreover theoretical analysis of antiviral ability with dust contamination and re-coated antiviral agents was carried out using a mathematical model to calculate the time-dependent antiviral effect of the filter under actual conditions of subway station. Our model can be used to apply on antiviral air filtration system of subway station for prevention of pandemic diffusion, and predict the life cycle of an antiviral filter.

Soongeuimyo is a shrine which has Liu Bei 劉備 as the main ceremonial figure and also Guan Yu 關羽 and Zhang Fai 張飛 as ceremonial figures as well as 8 others such as Zhege Liang, Zhao Yun, Ma Chao, Huang Zhong, Uang Bo, Zhou Zhang, Zhao Ru, and Guan Ping. Since one of the ceremonial figures is Guan Yu, it has been considered and discussed as a Guanwangmyo 關王廟. It is also witnessed by the terms called the East, South, or North tomb that were the existing Guanwangmyo, or even 'West' tomb 西廟. Of course, the relationship between Guanwangmyo and Soongeuimyo cannot be excluded because they both have Guan Yu. However, Soongeuimyo is different from Guanwangmyo in some aspects. Soongeuimyo was of a higher grade than Guanwangmyo in the quality of the ceremonial figures, and it had a completely different music and dances 악무, in which it included court music(雅樂), orchestra for court music(雅樂樂懸), and Yugilmu 六佾舞. Since the first enshrinement ritual in April 27, 1904, the period of Soongeuimyo Jerye was performed for only 4 years until the close in July, 1908, which made it less known. Furthermore, because Japanese Governor General used Soongeuimyo land as orphanages and schools for the blind and the dumb, the tomb areas were completely destroyed and the space to recall memories of Soongeuimyo was lost. However, Soongeuimyo Jerye was one of the country's important ceremonies conducted as Joong Sa 中祀 with complete assessment of traditional music and dance for Jerye. Also, as a Jerye that Go Jong 高宗 designed as a strong soldier policy after his coronation as an emperor to enhance Dae Han empire's military power, it has much significance as Dae Han empire's last national ceremony newly created besides Hwangu Jerye 圜丘祭 after his coronation.
