The purpose of this study is to discover the effects of Reality Therapy group program on leadership life skills, sociality, and classroom unity of elementary school children. The objects of this research are the 34 elementary school children at the K elementary school in the S area of Kyunggi-do, and randomly divided into two groups. Scientific methods are employed to test a Reality Therapy group program as a treatment for elementary school children to increase their level of leadership life skills, sociality, and classroom unity. For this study, one experimental group and one control group, composed of 34 students in total, are organized and treatment is conducted on these groups. The SPSS 12.0 statstics program is employed to analyze the questionnaires of both-test. Mann-Whitney U and Multiple Linear Regression test are used to analyze the result in order to verify the differences between experienced group and controlled group of pre-test scores within the groups. First, the statistics show a difference in leadership life skills factors(p<.001) between the experimental group and the control group. The Reality Therapy group program is a significant predictor of the leadership life skills. These statistics prove that experimental group has higher leadership life skills than the other group. Second, the statistics show a difference in sociality factors(p<.01) between the experimental group and the control group. The Reality Therapy group program is a significant predictor of the sociality. These statistics prove that experimental group have higher positive sociality than the other group. Third, the statistics show a difference in classroom unity factors(p<.001) between the experimental group and the control group. The Reality Therapy group program is a significant predictor of the classroom unity. These statistics prove that experimental group have higher positive classroom unity than the other group.

Experiments were carried out to elucidate the specific interactions between host plant, Phaseolus vulgaris, and symbiotic bacteria, Rhizobium Phaseoli. Purified P. vulgaris lectins and six species of cultured Rhizobium were subjected to agglutination test. Lectins from bean and R. phaseoli showed relatively high agglutination activity indicating that host plant lectins recognize carbohydrate moieties on the compatible Rhizobium cell surface. The specific carbohydrate receptors for binding of the lectins on the cell surface of R. phaseoli were found as mannose and galactose. The minimum concentration of sugars for the inhibition was 6.25mM. The lectin content of cultured plant roots was measured after germination and was maximum in 5-day seedlings. The nodulation was competitively inhibited by lectins for the plants cultured with Rhizobium cells. By immunochemical studies, there was some relationship in antigenic determinants between R. phaseoli and R. japonicum but no relationships were observed with other Rhizobium species. The results suggest that the infection by rhizobia to the roots of leguminous plants may be caused by the specific interaction of lectins with rhizobia.

The purpose of this study was to investigate the effect of social skill training on the class cohesiveness of Elementary School students. The experimental group received 12 times of the social skills training for 6 week period. And each training session which lasted for 40 minutes took place twice a week. A total of 59 5th grade students in randomly selected two classes of D Elementary School in N. Gyongsang participated in this study. They were divided into the two groups, again at random; an experimental group(N=30, Male=18, Female=12) and a control group(N=29, Male=15, Female=14). In this study, the class cohesiveness performance test reorganized into 20 items for the level of elementary students by Shin-suk Gang, was applied, after complemented. And, the collected data were analysed through SPSS 14.0. T-test was applied to find out the difference of the average between the experimental group and the control group and the average difference in the pre-and post-test of the experimental group alone, and to see whether the control group and the experimental group are homogeneous. The research design of this study is pre-and post-test control group design. The result of this study is as follows: The result of Independent t-test and Paried t-test on the cohesiveness score and sub-factor scores tells us that the experimental group which received the social skills training showed better achievement that deserves our attention compared to the control group. This result suggests that student's class cohesiveness(class atmosphere, mutual trust, morale, a sense of unity, communication) is positively affected by the social skill training. Accordingly, social skill training which develops class cohesiveness can be an effective strategy for elementary school students to make them more intimate and cooperative with their classmates.

CBD is a software development approach based on reusable component and supports easy modification and evolution of software. For the success of this approach, a component must be developed with high cohesion and low coupling. In this paper, we propose the two types of clustering analysis technique based on affinity between use-cases and classes and propose component identification method applying to this technique. We also propose component reference model and CBD methodology framework and perform a ease study to demonstrate how the affinity-based clustering technique is used in component identification method. Component identification method contains three tasks such as component extraction, component specification and component architecting. This method uses object-oriented concept for identifying component, which improves traceability from analysis to implementation and can automatically extract component. This method reflects the low coupling-high cohesion principle for good modularization about reusable component.

This study examines the extent to which community cohesion moderates the effects of neighborhood disorder on community integration among persons with mental illnesses(MI) who are living in the community. Stress process model, social disorganization theory, and neighborhood disorder model were considered with regard to the moderating effect of community cohesion. 692 persons with MI who utilized Community Mental Health Enhancement Centers were surveyed and analyzed, employing moderated regression model. Major findings showed that neighborhood disorder increased social integration. Community cohesion moderated the relationships of neighborhood disorder to three dimensions of community integration: physical, social and psychological integration. Implications for community intervention beyond the individual and service-level interventions were addressed in order to accomplish community integration for persons with MI.

The purpose of this study was to investigate the effect of weekend forest healing programs using urban forest on family cohesion and family relationship improvement and parental satisfaction with programs. 21 families (65 people)participated in the weekend forest healing program in Incheon Grand Park from April to August 2018. The program using family forest experience activity and forest healing therapy was newly constructed and implemented with 4 times 8 hours for 2 hours each week. The results of this study is that weekend forest healing programs for family gave a positive effect on family cohesion and family relationship, and parents' satisfaction showed high satisfaction in most items. Therefore, we concluded that forest healing activities are suitable for effective healing activities in modern society where functions such as family cohesion and emotional bond are recognized as important by improving family cohesion and family relationship. Further research should be extended to different types of families, and the development of diverse and interesting family-experience forest healing programs that reflect family needs should continue.

Among 120 microorganisms isolated from soil, KF-67 was the best producer of flocculant and was examined for flocculating ability in the kaolin clay and CaCl2 suspension. KF-67 was identified to be a species belong to the genus Agrobacterium sp. The influence of components of the culture medium for flocculant production by Agrobacterium sp. KF-67 was studied. The favorable carbon and inorganic nitrogen source for production of the flocculant were glucose and NH4NO3 and their addition concentrations were 2% and 0.1%, respectively. Addition of the organic nitrogen such as yeast extract, peptone and inorganic salt such as CaCO3 significantly increased the production of flocculant. These result indicated that the production of flocculant by Agrobacterium sp. was significantly affected by both organic nitrogen and inorganic salt. The components of the optimum culture medium were 2% glucose, 0.1% NH4NO3, 0.01% yeast extract, 0.01% peptone, 0.04% CaCO3, 0.03% NaCl in initial pH 7.5 when cultured with rotary shaker controlled at 3$0^{\circ}C$ and 120 rpm. Under the optimum culture medium, flocculant production was highly improved about 76% than that isolation medium.

Objectives：This study was done as a part of investigating individual and socioenvironmental factors affecting test anxiety in adolescent. The focusing of this study was detecting specific family enviromental factors affecting worry and emotionality of test anxiety. Methods：The subjects of this study were 880 middle and high school students in Seoul, Korea. To evaluate test anxiety level, Spielberger's Test Anxiety Inventory was applied and to evaluate familial factor, Moos and Moos' Family Environmental Scale was done. Results：The results were as follows. 1) Total and worry part of test anxiety scores were negatively correlated with cohesion and independence scores. Total, worry, and emotional part of test anxiety scores were positively correlated with achievement orientation and control scores. 2) High test anxiety group showed higher achievement orientation and control scores, and lower cohesion scores than low test anxiety group. 3) The higher socioeducational level of parents were, the higher three subscale (cohesion, independence, and achievement orientation) scores were, except control score. Conclusion：In therapeutic approach of adolescent's test anxiety, the importance of education and treatment of their parents should be emphasized. Parents should set their children's appropriate achievement goal, encourage their children's independency instead of control. Cohesion of familial members are also needed.
