As foreign immigrants increase dramatically, the number of ethnic residential areas also grow rapidly in Korea. Of those foreign workers, the majority is Korean Chinese who can speak Korean language fluently and share common culture as the same ethnicity. As of now they are concentrated on 8 areas in Seoul forming their own community with networks for living and finding job. This paper is to investigate the differences and similarities of Korean Chinese residential areas in Seoul. In order to do that the authors researched two typical areas of Garibong-dong and Jayang-dong. The former is bigger and established earlier, became the symbol of Korean Chinese community. The latter area is relatively small and formed recently. Those staying in Garibong-dong are characterized as; single, moved from main land China directly, small sized residing unit and lower income. The place is mainly for the first incoming people to provide convenient environment for adapting in Seoul. On the other hand those staying in Jayang-dong are characterized as; with families, moved from other parts of Seoul, relatively good residence and higher income. Therefore this place is the second residential area for those who became familiar with living in Seoul. As a result, this paper found the process of differentiation in Korean Chinese communities. This process would be continued as far as foreign immigration continues. Therefore further researches required on more detail process of differentiation for various ethnic groups.
Objectives: This study aim to determine adolescent meal time, which provides the important context of parent-child sharing time. We divided mealtime into family meal and alone meal, and analyzed the time/space context of each meal time as well as the social determinations. Method: We employed adolescents age 10-18 who live with married patents and attends school at the present (n=5,128) from the original data of Korean Time Use Survey. Results: More adolescent were engaged in family meal rather than eating alone in daily bases. However, the trend show difference by day of week and academic grade; family meal are more prevalent in weekends rather than weekdays. As adolescent reaches high school age, the proportion of eating alone beats the proportion of family meal time. Most of the meal occur at home. Having meal outside was relatively scares, especially on weekdays. Tobit and logistic analysis reveal that, on weekday meal, less school hours, more time spent at the private academy, having family leisure event, and long mother's housework hours were positively associated with family meal time. In weekend model, father's education gradient was associated with family meal time, showing higher the father's education level, there were higher chance of having weekend family meal. As for the eating alone, relevant factors were similar with family meal but the directions were the opposite; having family leisure were negatively associated with alone meal, both weekdays and weekend. Long academy hours, meal preparing and leisure alone were positively associated eating alone. Overall, weekday meal time was strongly linked with adolescent daily schedules and time use, while for weekends meal, in both family meal and alone meal, the influence of parent factors were discovered. Conclusion: The results indicates that alone meal and the family meal are not exclusively related but seem to be complementary. Families tend to enjoy family meal yet, there are some necessary situation that adolescent need to be on their own. Increase in ready-made food industries, growing independence of children by age seem partly allow adolescent children to eat alone. Careful attentions may require for monitoring weekends meal situation and the family factor of adolescent in future studies.

As fish communities are sensitive to natural environmental changes as well as anthropogenic pressures, their composition and characteristics help us to assess the aquatic ecosystem health. The fish fauna and the length-weight relationship of Zacco platypus in the Seomjin River system were investigated from July 2018 to May 2019. The collected species during the survey period were 49 species belong to 14 families including 19 Korean endemic and two endangered species. According to Bray-Curtis similarities, 14 sites were divided into four groups based on the fish community composition; two groups(group A, B) and two uncategorized sites(group C, D). There were significant differences between groups A and B(analysis of similarities, R=0.722, p=0.002). A similarity percentage analysis revealed that Z. koreanus(8.55%), Micropterus salmoides(6.90%), and Lepomis macrochirus (4.90%) contributed to these differences of fish assemblages between group A and B. Group A showed higher relative abundances of exotic species such as M. salmoides and L. macrochirus, while Z. platypus and Z. koreanus which are the common species in Korea, were the most dominant species in group B. Based on the length-weight relationship of Z. platypus, b values were varied from 2.82 to 3.80, indicating that growth patterns of the species were spatially different. This study could be served as baseline data for understanding fish fauna, assessing habitat characteristics based on the fauna, and identifying health conditions of Z. platypus in the Seomjin River system.

The flora of the vascular plants in Deoksesan Mt. and its adjacent areas, located at Inje-gun, Gangwon province, were surveyed for a total ten times from April of 2018 to July of 2020. The result of this survey revealed 457 taxa, consisting of 90 families, 287 genera, 404 species, 13 subspecies, 35 varieties, and 5 forms. Among them, 12 taxa were endemic plants to Korea, and 7 taxa were rare plants. Red list plants and those designated as controlled Korean biological resources, requiring special permission for export outside of the county, numbered 3 and 103 taxa, respectively. The floristic target species amounted to 83 taxa, specifically 8 taxa of grade IV, 26 taxa of grade III, 21 taxa of grade II, and 28 taxa of grade I. In addition, 14 taxa were classified as plants adaptable to climate change, and 4 taxa at their respective northern limits, first recorded in this study, were also investigated. Twenty-nine taxa of alien plants and 4 taxa of ecosystem disturbance species were also found in this area. Our results suggest that some species should be preserved and can serve as basic information with which to establish data on the preservation of resources, such as plant diversity and distributional changes on Deoksesan Mt.

In modern society, there is a growing demand for human tissue donation along with organ donation. However, the awareness of tissue donation and actual donation rates remain very low in South Korea. This study was undertaken to evaluate the current status of domestic laws and systems, and to compare them with the operation systems of major foreign countries, by reviewing literature and web sites of organ donation and registration. The authors present three measures to promote human tissue donation in Korea: integration of a dual legal system in a legal aspect, vitalization of the Opt-out system in terms of system operation, and activation of public relations in terms of social and cultural aspects. The Opt-out system, in particular, is the most effective way to activate transplants in the form of presumed consent of countries without undue pressure. However, the presumed consent method requires various stages of social public debate, and the requirement is a proper domestic understanding of the registration system for rejection. In conclusion, we believe the solution towards a positive inclination for organ donation is a public policy to increase the supply for organs and human tissue transplants, and positive perception of donations, public promotion, and support for postmortem donors and their families.

This study was conducted to survey students' current eating behavior and nutritional knowledge to provide researchers with basic data that can help students with positive, practical, and healthy eating habits. For this purpose, a self-administered questionnaire was distributed to students of a vocational high school located in Gyeongsangnam-do. A total of 270 questionnaires were collected from a convenience sample and the data were analyzed using SPSS Version 25.0. The results are as follows. First, 57.40% of students lived with "parents," and 55.56% of students' household monthly income levels were "Low." Second, as for the eating behavior of the subjects, the students who ate 'two meals' a day showed the highest at 64.81%, 'one meal' occupied 17.41%, and those who ate one meal a day, 'School cafeteria' was the eating place most frequently mentioned (65.96%). Third, when students were classified based on their nutritional knowledge levels, "High" group comprised 37.78%, "Moderate" group 37.41%, and "Low" group 24.81% of the total students. Regarding the experience of nutrition education, 64.44% answered 'no experience of nutrition education' in the last 12 months, and among the 35.56% of students who had received nutrition education, 72.92% received the education from school teachers. Based on these results, to prevent problems with the eating habits that can occur to vocational high school students, organic cooperation between families, schools, and local communities is required. Furthermore, full support from the government is needed. In addition, more efforts are needed for practice-oriented dietary education so that nutritional knowledge can be converted into correct eating behavior.

Early diagnosis and intervention of dementia is critical to minimize future risk and cost for patients and their families. The purpose of this study was to develop and validate Figure-Copy Test(FCT), as a new dementia screening test, that can measure neurological damage and cognitive impairment, and then to examine whether the grading precesses for screening can be automated through machine learning procedure by using FCT imag es. For this end, FCT, Korean version of MMSE for Dementia Screening (MMSE-DS) and Clock Drawing Test were administrated to a total of 270 participants from normal and damaged elderly groups. Results demonstrated that FCT scores showed high internal constancy and significant correlation coefficients with the other two test scores. Discriminant analyses showed that the accuracy of classification for the normal and damag ed g roups using FCT were 90.8% and 77.1%, respectively, and these were relatively higher than the other two tests. Importantly, we identified that the participants whose MMSE-DS scores were higher than the cutoff but showed lower scores in FCT were successfully screened out through clinical diagnosis. Finally, machine learning using the FCT image data showed an accuracy of 73.70%. In conclusion, our results suggest that FCT, a newly developed drawing test, can be easily implemented for efficient dementia screening.

This study aims to analyze everyday caring activities of young working single-person households. To collect the data, we interviewed 10 working single-person households. The topics are composed of 3 parts: 1) the everyday life of single-person households; 2) caring activities and household labor; 3) the experience of caring activities. The results are as follows : In comparison with families living together, single-person households carry out everyday caring activities alone, so they found a new meaning in caring activities and household labor. In particular, they were fully aware of the importance of everyday caring activities even though they sometimes felt the caring activities were uncomfortable. On the other hand, they improved their technique and ability for caring activities, and they felt satisfied with the caring activities. We found the meaning of everyday caring activities to be an essential condition for the independence of single-person households.
Environmental risk assessment of living modified (LM) crops is essential for their cultivation. In this study, we cultivated β-carotene enhanced transgenic soybean (LM soybean) and non-LM soybean (Gwangan) in living modified organism (LMO) isolated fields, and investigated changes in the insect fauna using three types of collection methods for three years. In total, 331,483 individual insects and arachnids, representing 82 families in 14 orders, were captured during the study. Totals of 166,518 and 164,965 individual insects and arachnids were collected from LM soybean and Gwangan, respectively. Throughout the study, although there were differences between the investigation year, region, and methods, there were no significant differences between the population densities of insect pests, natural enemies, and other insects on LM soybean and non-LM soybean. Also, there were no statistically significant differences between varieties in the results of the species diversity analysis. The data on insect species population densities were subjected to multidimensional scaling (MDS), which did not distinguish between the two varieties, LM soybean and the non-LM soybean, in all cultivated fields. However, the results of the MDS analysis were completely divided into six groups based on the yearly survey areas. These results provided the insect diversity for an environmental risk assessment of LM soybean and suggested that the guideline could be useful to detect LM crops.
