The safety factor of an infinite slope tends to be analyzed as lower when the effects of root cohesion are not considered into the equation. Thus, it is essential to consider regional characteristics such as root cohesion and crown density in order to obtain a reasonable safety factor value. In this study, The safety factor of the landslide model, both before and after considering crown density and root cohesion, was calculated and a comparative analysis was carried out. The safety factor is increased by the effect of roots cohesion of the analysis results, the amount of increase in safety factor along the inclination of the slope angle has been analyzed with various things, the effect of reinforcing the roots cohesion, slope of the lower angle it was found that the higher the safety factor increase.

The purposes of this study are to examine the differences of gender role identity according to general characteristics, parenting behavior, and family function, and to find out the main predictors of gender role identity, in order to further test the mediating effects of family function between parenting behavior and gender role identity among middle school students. Six hundred-fifty 3rd graders from three middle schools in Busan participated in this study. The results showed that the significant variables for predicting the masculinity of gender role identity include family cohesion, and parenting behaviors (father's reasoning, mother's over-expectation) and monthly household income, respectively. The significant variables for predicting femininity were family cohesion, and father's intrusive parenting behaviors, father's educational background and the mother's affection, respectively. The results indicated that for masculinity, family cohesion played the full mediator with the father's monitoring behavior and the partial mediator with the father's reasoning behavior. Similarly, for the mother's reasoning and affection, family cohesion played a full mediator. For femininity, the family cohesion played the full mediator with the father's affection and the partial mediator with the mother's affection. Similarly, for androgyny, the family cohesion played a role of full mediator with the father's monitoring, reasoning, affection and mother's reasoning and affection. In other words, the parents'positive parenting behaviors affected the family cohesion, and in turn, had an impact on the formation of the gender role identity.

Adopting cohesive soil as geocell-pocket infill materials is not fully accepted by researchers in the field of road engineering. The cohesion that may inhibit the lateral limitation of geocells is a common vital idea that exists within every researcher. However, the influence of infill materials' cohesion on geocell-reinforced performance is still not thoroughly determined. The mechanism behind this still needs to be studied in depth. This study initially discussed the relationship between subgrade bearing capacity, geocells' contribution to reinforced performance, and infill materials' cohesion (IMC). A law was proposed that adopting the soil with high cohesion as infill materials benefited the subgrade bearing capacity, but this was attributed to the superior mechanical properties of infill materials rather than geocells' contribution. Moreover, the vertical and lateral deformation of subgrade, coupling shear stress and confining stress of geocells, and deformation of geocells were deeply studied to analyze the mechanism that high cohesion can inhibit the geocells' contribution. The results indicate that the infill materials with high cohesion result in the total displacement of the subgrade toward to deeper depth, not the lateral direction. These responses decrease the vertical coupling shear stress, confining stress, and normal displacement of geocell walls, which weaken the lateral limitation of geocells.

This study aims to compare the husband's stress, communication, family cohesion and adaptation which contribute to the internal structure of conjugal understanding between families living apart from one another and those living together. The data for analysis was derived from questionnaires. 172 husbands from families living apart and 185 husbands who live with their families. The data was treated by spss pc+ program and the methods of analysis were frequency, t-test and one-way ANOVA. The results of this study were as follows : 1. Husband's stress in conjugal understanding in families living apart was higher than those who live with their families. 2. Between the husbands whose families are living apart and those who are living together, there were no significant differences in effort levels to overcome stress, family cohesion, family adaptation and communication needs for conjugal understanding. 3. Husbands who live with their families communicate differently according to the degree of their stress levels. 4. Low stress levels led to high family cohesion and family adaptation in both cases. 5. High communication levels led to high family cohesion and family adaptation in both cases.

The growth in the amount of selling of family-look clothing was recently observed in an domestic apparel industry. The issue related to the consumers' purchase behavior toward family-look clothing would closely connected with their relationship among family members, especially, the family cohesion. To understand the consumers' purchase behavior toward family-look clothing, the study investigated the relationship with the purchase behavior toward family-look apparel and family cohesion as well as other clothing behavior. Most of the respondents$(76.7\%)$ had never purchased family-look clothing and most of the consumers$(75.7\%)$ who had purchased family-look clothing expressed their satisfaction with the purchase. The results revealed that the family cohesion had statistically significant influence on purchase intention toward family-look clothing, that is, consumers who were closely linked together with their family tended to have an intention to purchase family-look clothing.

Human Fen1 protein (hFen1) plays an important role in Okazaki fragment processing by cleaving the flap structure at the junction between single-stranded (ss) DNA and doublestranded (ds) DNA, an intermediate formed during Okazaki fragment processing, resulting in ligatable nicked dsDNA. It was reported that hChlR1, a member of the cohesion establishment factor family, stimulates hFen1 nuclease activity regardless of its ATPase activity. In this study, we found that cohesion establishment factors cooperatively stimulate endonuclease activity of hFen1 in in vivo mimic condition, including replication protein-A-coated DNA and high salt. Our findings are helpful to explain how a DNA replication machinery larger than the cohesion complex goes through the cohesin ring structure on DNA during S phase in the cell cycle.

The purpose of this study is to examine the associations among family cohesion, self-efficacy, and school adjustment in adolescence. This study investigated these interrelationships using structural equation modeling. The results indicated that family cohesion had effects on school adjustment both directly and indirectly through self-efficacy. The mediating effect of self-efficacy was statistically significant. These results imply that family cohesion and self-efficacy need to be emphasized as a strategy to improve school adjustment among adolescents.

Group features such as group cohesion and consistency on appropriation(COA), which have been constructed through social interactions, should be noted for characterizing online game, especially, clan based massively multi-players online game (MMOG). This study attempted to identify the relationship between group characteristics and users' effectiveness of MMOG considering group experience. For this purpose, a research model was suggested: group cohesion and COA are variables for explaining group features, perceived use control is a variable for individual competency of playing MMOG, and perceived winning and perceived enjoyment are dependent variables. Moreover, group experience was included as a moderating variables for two relationships, group cohesion-preceived winning and COA-perceived winning. For the validation of this research model, 100 users for Sudden Attack which is one of very well known MMOG games were surveyed by questionnaires. Before survey, they were grouped into 10 teams and were played over ten times by team for perceiving group consciousness. In result, most hypotheses were statistically supported except the relationship between group cohesion and perceived winning.

The purpose of this study was to investigate the relationships between children's self-concepts and (1) types of functional family systems. (2) family cohesion and adaptability levels, and (3) the satisfaction of children with their current family systems. The subjects of this study were 347 middle S. E. S. children (168 boys, 179 girls) in grade 6. Analysis of functional family systems was by The Family Adaptability and Cohesion Evaluation Scales III(1985) of the Circuplex Model (Olson et al., 1979). The Self-concept Inventory (Lim Jae Leun, 1987) was used to assess children's self-concepts. The data were analyzed with one-way ANOVA, $Scheff{\acute{e}}$ and Pearson correlation. It was found that there were no differences in children's self-concepts by types of functional systems. There were differences in children's self-concepts by family cohesion and adaptability levels. That is, the higher the level of cohesion and adaptability the more positive the child's self-concept. The more the child was satisfied with his/her current family system, the more positive the child's self-concept. Children whose family systems were at a high level of family cohesion and adaptability were more satisfied with their current family systems.

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.
