This study attempts to explain how depression among community elderly relate to suicidal ideation and whether or not the psycho-social characteristics of elderly persons moderate the relationship between these two variables. This study was conducted in Seoul, Busan, and Daegu and included 273 persons 65 years and above who were using senior welfare centers in the communities. For the questionnaire and analysis, this research uses the Health Care, Life Event, Self-esteem, Family Assessment scales. This research utilizes a wide range of statistical analyses, such as descriptive analysis, Pearson's correlation, reliability analysis, multiple regression, and general linear modeling. The calculations employed the use of SPSS/PC+ 12.0. This research indicates, among other things, that elderly persons with a high level of depression and psycho-social characteristics show a tendency toward higher suicidal ideation and that the level of self-esteem, life event, and family communication plays a moderating role in the relationship between depression and suicidal ideation among community elderly. In conclusion, elderly persons who experienced with a high level of psycho-social characteristics shows a relatively greater tendency toward suicidal ideation when compared to elderly persons having a low level of psycho-social characteristics. The intervention's effectiveness in reducing suicidal ideation can reinforce self-esteem, and cope with stressful life events and family discord as prevention strategy to reduce risk factors for suicide in late life.

Objectives : The management of disaster should be immediate and sustainable. Further, it is hard to predict where the disaster will occur, using pre-exists governmental and non-governmental organizations are important. In this study, we tried to investigate the associated activities of organizations performed in Ansan city, in Sewol ferry accident. Methods : A total 121 workers in 25 organizations were surveyd about organizations which they worked with, kind of works performed, frequency of meetings, satisfaction in activities and factors associated with dissatisfaction in usual state and in Sewol ferry accident state, respectively. The differences between those two situations were analyzed using paired t-test for continuous variables and Chi-square test or McNemar test for categorical variables. Results : The total number of linkage of institutions were decreased(from n=397 to n=251) and the mean scores of rating satisfaction were significantly lower in most of organizations in disaster state. The rigid policy in performance evaluation was more likely associated with dissatisfaction in disaster state than usual state(p=0.045). Conclusions : For effective linkage of institutions, preparedness, such as understanding the capability of organizations in the communities and developing the protocol for associated activities, is important. The unnecessary and effortful performance evaluation should be sublated.

To profile the microbial compositions of Korean traditional fermented paste made from whole soybeans, Doenjang and Cheonggukjang, and compare their taxonomic differences, we analyzed the V3-V4 region of 16S rRNA of naturally fermented foods by using next generation sequencing. α-Diversity results showed that values indicating bacterial community abundances (OTUs) and richness (ACE, Chao1) were statistically significant (p=0.0001) in Doenjang and Cheonggukjang. Firmicutes was the most common phylum in both groups, representing 97.02% and 99.67% in the Doenjang and Cheonggukjang groups, respectively. Bacillus was the most dominant genus, accounting for 71.70% and 59.87% in both groups. Linear discriminant (LDA) effect size (LEfSe) analysis was performed to reveal the significant ranking of abundant taxa in different fermented foods. A size-effect threshold of 2.0 on the logarithmic LDA score was used for discriminative functional biomarkers. On the species level, Bacillus subtilis, Tetragenococcus halophilus, and Clostridium arbusti were significantly more abundant in Doenjang than in Cheonggukjang, whereas Bacillus thermoamylovorans, Enterococcus faecium, and Lactobacillus sakei were significantly more abundant in Cheonggukjang than in Doenjang. Permutational multivariate analysis of variance (PERMANOVA) showed that the statistical difference in microbial clusters between the two groups was significant at the confidence level of p=0.001. This research could be used as basic research to identify the correlation between the biochemical characteristics of Korean fermented foods and the distribution of microbial communities.

The purpose of this study was to investigate the prevalence of social anxiety among late School-aged Children and identify factors influencing the tendency to social anxiety. A self-report survey was conducted with primary school children who were in the 6th grades. Two hundred and seventy eight children were included in the study. The instruments utilized in this study were SASCA-K (Korean Social Anxiety Scale for children and adolescents), SES(Self-esteem Scale), CAPS(Child and Adolescent Perfectionism Scale), DSRS-C(Depression Self-Rating Scale for Children), and IPPA-R(Inventory of Parent and Peer Attachment-Revised version). Data were analyzed using descriptive statistics, t-test, One-way ANOVA, Pearson correlation and multiple regression with SPSS WIN 23.0 program. Social anxiety for the schoolchildren was positively correlated with perfectionism and depression, whereas self-esteem and attachment security was negatively correlated with social anxiety. Stepwise multiple regression analysis showed that 38.0% of the variance for social anxiety was significantly accounted for by self-esteem, self-oriented perfectionism, depression, attachment security (Father-communication). The most significant factor influencing social anxiety was self-esteem. Findings suggest that expanding health education, counseling and school-based health education programs is necessary to prevent and intervention mental problems of late School-aged Children through integrated intervention by schools, families and communities.

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.

In this study, the benthic environmental and microbial community structure were investigated by mixing granulated coal ash(GCA) and contaminated estuary sediments. Estuary sediments and GCA were mixed in a ratio of 8:2 and allowed to interact for 1 month, then sediment environmental factors were investigated. The pH of the experimental sediment was mixed increased to 11. The concentration of DIP(Dissolved inorganic phosphorus) in the experimental case decreased by 30 % compared to the control case, and this should be due to formation of calcium phosphate through the chemical reaction of DIP and calcium which diluted from GCA. The high abundance of Gammaproteobacteria seen in the experimental sediment compare to the control can af ect the DIP reduction. The DIN(Dissolved inorganic nitrogen) concentration increased over two times in the experimental case than the control, and this should be due to the high pH condition and release of NH₄⁺-N from the GCA. Microorganisms related to nitrogen circulation were not identified in both the control and experimental cases. It was confirmed that the GCA were effective in reducing the DIP concentration in contaminated estuary sediment, and that benthic microbial communities were shown to influenced the phosphorus circulation.

Earthquakes have occurred owing to movements on a fault since several billion years ago. Research on the relationship between earthquakes and groundwater began in the 1960s in the United States, but related works, including hydrogeochemistry research, only began in the 2010s in South Korea. In this study, domestic studies on the relationship between earthquakes and groundwater until 2021 were collected from the Web of Science and characterized by subject area (groundwater level, hydrogeochemistry, combination of the two, and others). The results showed that the number of published articles per year was positively correlated with the 2011 Tohoku earthquake, 2016 Gyeongju earthquake, and 2017 Pohang earthquake, with the maximum numbers observed in 2011, 2018, 2019, and 2020. Most studies on the relationship between earthquakes and groundwater level addressed groundwater level fluctuations in the duration of the subject earthquake, with little consideration of the precursors. Groundwater level monitoring data, as well as hydrogeochemical information and microbial communities, may contribute to a more detailed understanding of groundwater flow and chemical reactions in bedrock caused by earthquakes. Therefore, the establishment of a national groundwater monitoring network for seismic monitoring and prediction is required.

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.

The purpose of this study is to develop a sustainable dietary education program using garden vegetables for middle school students. Textbook analysis and demand survey were conducted before developing the program. Ten textbooks of technology and home economics for middle and high school students were analyzed and the results showed that none of the textbooks covered food gardening. Two hundred and six middle school students participated in the demand survey and the results revealed that students lack an understanding of food gardening despite high interest. Therefore, six sessions of a sustainable dietary education program using garden vegetables were developed based on a six-step DESIGN procedure. Then, the content validity of the program was evaluated by three experts and the program was revised based on the results. This dietary education program will lead students to live a sustainable diet, eventually benefiting the health and wellness of individuals, communities and ecosystems.

This study examines the social discourse on the characteristics of the learning community in the untact era, and discusses the directions that learning communities for children could explore and consider in the pandemic situation and beyond. For this purpose, big data for one year, from January 20, 2020 to January 20, 2021, were collected through internet portal sites (includingincluding Google News, Daum, Naver and other News surfaces), using two keywords "untact" and "learning community", and analyzed by employing a word frequency and network analysis method. The analysis results show that several important terms, such as 'village education community', 'operation', 'activity', 'corona 19', 'support', and 'online' are closely related to the learning community in the untact era. The findings from this study also have implications for developing the learning community as an alternative model to fill the existing gaps in public care and education for children during the prolonged pandemic and afterwards. In conclusion, the study findings highlight that it is meaningful to identify key terms and concepts through word frequency analysis in order to examine social trends and issues related to the learning community.
