This study was designed to evaluate the social support network of schizophrenic patients. 64 schizophrenic patients being treated as out-door patient were compared with 30 neurotic control patients. Schizophrenics were divided into positive, subpositive, subnegative and negative subgroups by present symptom and social network of both schizophrenics and control group were evaluated. The results are as follows: 1) Social network of schizophrenics was smaller than that of control group. Size of social network of schizophrenics was 10.6 and that of control group was 23.5. 2) In both kin and nonkin, social network of schizophrenics was smaller than that of control group. Of the kin, schizophrenics were more supported by wife or husband, father, and mother, but were less supported by brother, son and other relatives. 3) There was no difference in the kin or nonkin or total supporters between the four subgroups of schizophrenics. But, subgroup of schizophrenics which was divided as having negative symptom had smaller network than control group in active formal and informal supporters. 4) When divided into 4 support areas, schizophrenics was remarkably less supported in emotional, instrumental and appraisal support area than control group, but there was no difference in the informational support areas. 5) Compared with control group, schizophrenics more often mentioned parent and ten often mentioned nonkin supporter as the one that is most important to him. 6) Schizophrenics had smaller cluster and less leisure activity than control group. Subgroup of schizophrenics who was divided as having negative symptom had less frequency of leisure activity than other subgroups.

Positive affect has beneficial consequences in various life domains including social relational aspect. This study proposes that 'joy,' a highly arousing positive social emotion, promotes emotionally supportive reactions during a social interaction. In Study 1, after controlling for confounding personality characteristics (e.g., extraversion, agreeableness, adult attachment) and cognitive variables (e.g., empathy, self-esteem), positive affect predicted the amount of emotional support and enthusiasm one showed to a person who was describing a positive experience. The arousal dimension of positive emotion appeared to be the key in creating this outcome. Study 2 found that people were most likely to react in supportive ways (e.g., more laughing, emotion sharing, and active-constructive responses) to other's conversation after viewing a joy-inducing (rather than pride, awe, calm) film clip. These results partly explain why happy people are socially popular and suggest that one of the central functions of "joy" is to promote social bonding with others.

The support of the PEMFC membrane plays a key role in improving mechanical durability. The e-PTFE used as a support is chemically stable, so electro-chemical degradation in the PEMFC driving process has been rarely studied. In this study, we investigated whether e-PTFE is chemically stable to radicals and hydrogen peroxide during Fenton reaction. After the Fenton reaction, the main chain of e-PTFE broke, resulting in a change in the chemical structure and morphology of the support, resulting in a decrease in tensile strength. The results of this study showed that electrochemical degradation of the membrane ionomer in the PEMFC process occurs inside the membrane by radicals and hydrogen peroxide, so that electrochemical degradation may also occur at the e-PTFE support in the cell.

PLLA scaffold loaded with gentamicin sulfate (GS) was prepared by emulsion freeze-drying method for the prevention of infection and the improvement of wettability. i.e., the cell- and tissue-compatibility. GS-loaded PLLA scaffolds were characterized by scanning electron microscopy (SEM), mercury porosimetry and blue dye intrusion, and the GS release pattern was analyzed by high performance liquid chromatography (HPLC). GS-loaded PLLA scaffolds with porosity above 50%, medium pore size ranging from 30 to 57 ${\mu}{\textrm}{m}$ (with larger pore diameters greater than 150 ${\mu}{\textrm}{m}$), and specific pore area in the range of 35 to 75($m^2$ /g )were manufactured by varying processing parameter as GS concentration. It was observed that GS-loaded PLLA scaffolds were highly porous with good interconnections between pores for allowing cell adhesion and growth. These scaffolds may be applicable for scaffold as structures that facilitate either tissue regeneration or repair during reconstructive operations.

When hot-rolled wide flanges are used as vertical compressive or bending member, opening web are often to take a space for equipments of pipe or duct. The Web of hot-rolled wide flange steel with opening may be analyzed as a rectangular plate, subjected to in plane force, and the buckling load is governed by the ultimate force of web. The result of the theory showed close agreement with the result of the finite element analysis. It was also shown that the buckling loads of stiffened opening plates could be larger than those of the plate. The stiffened opening plates for the 4-side simply supported case showed more stiffening effect than the Two Opposite Elastic Supports and Two Other Opposite Simply Supports case. In this study, we proposed the effective opening sizes that buckling loads of stiffened opening plate could be greater than those of the plates.

Association rule is the technique to represent the relationship between two or more items by numerical representing for the relevance of each item in vast amounts of databases, and is most being used in data mining. The basic thresholds for association rule are support, confidence, and lift. these are used to generate the association rules. We need standardization of lift because the range of lift value is different from that of support and confidence. And also we need standardization of support and confidence to compare objectively association level of antecedent variables for one descendant variable. In this paper we propose a method for standardization of association thresholds considering marginal probability for each item to grasp objectively and exactly association level, check the conditions for association criteria and then compare association thresholds with standardized association thresholds using some concrete examples.

This study was designed to explore the structural relationship of social support, acculturative stress and parenting stress which influenced child abuse among married immigrant women in Korea. For study 195 married immigrant women participated and structured questionnaire was used. This study identified that the variable of parenting stress directly affected child abuse and the variable of acculturation stress indirectly affected child abuse with a variable of parenting stress as a mediator variable. In addition, the variable of social support indirectly affected parenting stress with a variable of acculturation stress as a mediator variable. Also, the variable of social support did not directly affect child abuse, but it was verified as a protective factor to reduce the risk of child abuse. This study suggested the social interventions to prevent child abuse among multi-cultural families based on the study results.

The purpose of the study is to investigate the impact on mental health of university students from job-seeking stress, career decision-making, and social support. 429 university students from the three universities in J province were instructed to answer structured questionnaires, and the data was analyzed by t-test, ANOVA, Pearson Correlation, and Regression analysis using SPSS 24.0 software. The results reveal that job-seeking stress shows positive correlation to mental health, whereas career decision-making and social support show statistically significant negative correlations. The results also show that the factors that affect mental health are job-seeking stress and social support with Exploratory power of 48.9%. It is necessary to develop and apply measures that consider impact factors such as job-seeking stress to improve mental health of university students. It is also important to establish and maintain a support system for mental health.
