The purpose of this study was to identify factors affecting college-based stress and develop stress-relieving educational programs. Data were collected from 169 students in G-province, from June 15th to july 15th, 2020. Analysis was done using IBM SPSS 21.0 for frequency, percentage, average, standard deviation, t-test, ANOVA, Pearson correlation coefficient, and Multiple regression. College-based stress positively correlated with life event, life event importance, interpersonal emotion, and self-control. The most important factor affecting college-based stress was psychological hardiness (β=-.323, p<.001), followed by club activities (β=.237, p<.001), interpersonal conflict (β=.215, p=.001), grade-2 (β=-.203, p=.001), department adaptation (β=.161, p=.010), and age-21 (β=-.149, p=.024). The explanatory power was 44.4% (F=42.43, p<.001). The results of this study are expected to be used as basic data for the development of educational programs for stress reduction at the university level. Therefore, educational programs considering age and grade, using club activities as support systems, and dealing with psychological hardiness and department adaptation are needed.

The purpose of this study was to provide information on adoptive families and obtain the basis data for adoption-related programs that are useful to adoptive families by examining their experiences in the adoption process, post-adoption adaptation, and adoption programs. For the study, in-depth interviews were conducted on six mothers who publicly adopted elementary school children and had expressed high satisfaction with adopted families and their willingness to participate in this research voluntarily. The main results exhibited parents' happiness post-adoption along with positive changes, such as internal growth, marital love growth, favorable response from others, and child's unexpected responses to adoption. However, open adoption mothers have coped with efforts to sympathize with and accept their children's feelings as they suffer from adoption, and with active support from their spouses, parents, and their own children. Open adoption mothers participated in various adoption-related programs, support, and voluntary self-help groups provided by adoption agencies or public organizations, and above all, their experience in self-help groups and peer groups of adopted children was found to be very useful. Based on these main results, we suggested strengthening welfare services for open adoption families, implementing education to better understand adoption, education for school teachers, students, and welfare staff, providing practical programs for adoptive families, and promoting self-help groups.

Background: The purpose of this study is to assess the degree of self-awareness, recognition of others, and adaptation to college life of dental hygiene students, and to identify the factors affecting college life adjustment. Methods: The effect size was calculated using the G*power 3.1.9.4 program, based on the data of 191 people who agreed to participate in the questionnaire. Independent samples t-test, one way ANOVA, Post HOC Scheffe, correlation analysis, and multiple regression analysis were conducted to explore the difference and correlation between self-awareness, perception of others, and college life adjustment according to general characteristics. Results: A significant positive correlation was found in self-awareness (r=.301). The highest positive correlations were with social adjustment in both private (r=.340) and public self-awareness (r=.331) (p<0.01). Recognition of others (r=-.051) showed a negative correlation with college life adjustment, though it was not statistically significant. As factors for adapting to college life, private self-awareness (β=.232) and public self-awareness (β=.254) had a positive (+) effect, and internal self-awareness (β=-.205) was found to have a negative (-) effect (p<0.01) Conclusion: The self-awareness and recognition of others among dental hygiene students influence their smooth adjustment to college life. Improvement measures are recommended to enhance adaptability to college life and develop core competencies related to their major

The purpose of this study was to determine the discrete intelligences from multiple intelligence affecting the social adaptive behavior, help to understand their relation and draw educational implications to be used in supporting gifted students who have social and emotional difficulties by comparing and analyzing the relation between multiple intelligence and social adaptive behavior of gifted and general elementary students. The conclusions of this study are as follows. First, the levels of both multiple intelligence and social adaptive behavior were significantly higher in gifted elementary students compared to general ones on all sub-factores, indicating that the gifted elementary students are more adaptive in such constructs as self-efficacy, self-esteem, communicative skill, school life and interpersonal skill compared to general ones. Second, the association between multiple intelligence and social adaptive behavior was statistically significant both in gifted and general elementary students, indicating that the two constructs have close relation with each other. Third, for the gifted elementary students, the logical-mathematical and interpersonal intelligences had explanatory powers for self-efficacy, self-esteem, communicative skill, adaptation in school life, interpersonal skill while, for the general ones, intra- and inter-personal intelligences had explanatory powers for most domains of social adaptive behaviors, indicating that development of intelligences affecting the social adaptive behavior many have positive effects on social and emotional development of both gifted and general elementary students.

Purpose: The purpose of this study was to develop an experience-based sex education program to improve adjustment to puberty in elementary school students in the upper grades and to verify its effectiveness. Methods: This study had a pretest-posttest nonequivalent control group design. The subjects of this study were a total of 95 sixth-graders in Y city (experimental group: 48, control group: 47). The measurement variables were sexual knowledge, body image, self-esteem, and satisfaction with life. Four sessions of the experience-based sex education program to improve adjustment to puberty, consisting of 40 minutes per session, were provided to the experimental group. Results: Children's sexual knowledge, self-esteem, and satisfaction with life in the experimental group, which participated in the experience-based sexual education program to improve adjustment to puberty, showed a significant increase compared to the control group. However, there was no statistically significant difference in body image. Conclusion: This study presents the development of an experience-based sex education program for adjustment to puberty to overcome the shortcomings of existing sex education programs that are limited to sexual knowledge and attitudes, and also verified that the sexual knowledge, self-esteem, and life satisfaction of the elementary school students who were provided with the program improved meaningfully.

Since self-organizing map (SOM) preserves the topology of ordering in input spaces and trains itself by unsupervised algorithm, it is Llsed in many areas. However, SOM has a shortcoming: structure cannot be easily detcrmined without many trials-and-errors. Structure-adaptive self-orgnizing map (SASOM) which can adapt its structure as well as its weights overcome the shortcoming of self-organizing map: SASOM makes use of structure adaptation capability to place the nodes of prototype vectors into the pattern space accurately so as to make the decision boundmies as close to the class boundaries as possible. In this scheme, the initialization of weights of newly adapted nodes is important. This paper proposes a method which optimizes SASOM with genetic algorithm (GA) to determines the weight vector of newly split node. The leanling algorithm is a hybrid of unsupervised learning method and supervised learning method using LVQ algorithm. This proposed method not only shows higher performance than SASOM in terms of recognition rate and variation, but also preserves the topological order of input patterns well. Experiments with 2D pattern space data and handwritten digit database show that the proposed method is promising.

This study is to analyze the influence of the digital divide on the digital daily life of the elderly. Adaptation tendencies for digital divide were measured and classified into groups for elderly people over 60 years old. And digital communication skills, digital confidence, digital self-control, and digital life satisfaction were measured. The research model used a cross over design model and a dual mediation model. As a result of the study, first, it was found that a group with high adaptive accessibility to the digital divide had a positive effect on the overall digital daily life. Second, a group with high adaptive literacy to the digital divide had a positive effect on the digital self-control. Third, digital communication skill has a positive effect on digital life satisfaction, and digital confidence and digital self-control play a mediating role. Based on these findings, we discussed strategies to overcome the digital divide in old age.

Background and objective: The elderly living in homeless living facilities for a long time suffer from various mental health problems. This study aims to determine the psychological, emotional, and social effects of a horticultural therapy program composed of gardening activities, which was designed based on the semantic structures of life for the homeless elderly living in the facilities for a long time. Methods: A total of 12 subjects (6 in the control group and 6 in the experimental group) participated in the study. The horticultural therapy program consisted mainly of gardening activities, and a total of 16 sessions were conducted once a week for 16 weeks, 60-90 minutes per session. The subjects were tested to evaluate their self-esteem, depression, and horticultural activities. The data were analyzed using the Mann-Whitney U test, Wilcoxon rank test, and Friedman test, which were nonparametric tests, conducted at a 95% significance level. Results: First, in the case of self-esteem, a significant difference was found between the groups, 20.00 points (SD = 5.69) in the control group, and 25.50 points (SD = 3.73) in the experimental group (p = .034). Second, in the case of depression, no statistically significant difference was found in the posttest. Finally, in the case of the horticultural activity evaluation, the scores of most variables gradually and significantly increased during the program [Verbal interaction during activity (p = .006), Self-concept and identity (p = .006), Need-drive adaptation (p < .001), Interpersonal and social relations (p < .001)]. Conclusion: These results support that the horticultural therapy program could help the elderly improve psychological relaxation, emotional stability, and social relationships. In order to generalize the results, it is suggested to increase the number of subjects or conduct additional repetitive experiments in further research.

Change of carabid beelte (Coleoptera, Carabidae) diversity and population structures in Woopo Wetlands (Changneung-Gun, Gyeungsangnam-Do, S. Korea) were investigated after flooding events. During the investigation period, 11 species belonging to five genera were identified. Dolichus halensis halensis(Schaller), Chlaenius (Ch.) pallipes Gebler, Ch. (Ilaenchus) naeviger Morawitz, and Pheropsophus (Stenaptinus) jessoensis Morawitz were the predominant species in Woopo Wetlands. Floods occurred twice, August and September in 2004. After the flooding events, species diversity decreased and species assemblage structures changed dramatically. Changes of the diversity and species assemblage structures were more evident in August then in September, because water level was much higher and inundation period was longer than September. A non-linear patterning algorithm of the Self-Organizing Map (SOM) was applied to discover the relationship between flooding events and carabid beetles community dynamics. Although abundance of the majority species decreased after the flooding events, that of the predominant species increased. Further detailed studies on species distribution and emigration patterns will likely bring a new insight in understanding of the adaptation mechanism of carabid beetles in wetlands.

In this paper, we propose a method of cooperative control (T-cell modeling) and selection of group behavior strategy (B-cell modeling) based on immune system in distributed autonomous robotic system (DARS). An immune system is the living bodys self-protection and self-maintenance system. these features can be applied to decision making of the optimal swarm behavior in a dynamically changing environment. For applying immune system to DARS, a robot is regarded as a B-cell, each environmental condition as an antigen, a behavior strategy as an antibody, and control parameter as a T-cell, respectively. When the environmental condition (antigen) changes, a robot selects an appropriate behavior strategy (antibody). And its behavior strategy is stimulated and suppressed by other robots using communication (immune network). Finally, much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and immune network hypothesis, and it is used for decision making of the optimal swarm strategy. Adaptation ability of the robot is enhanced by adding T-cell model as a control parameter in dynamic environments.
