When people judge how competent others are in society, the judgement highly depends on the social context. The objective of this study is to confirm whether the levels of social anxiety symptoms influence the contextual effect on people’s judgement toward others’ social competence. In the experiment, a total of 120 individuals (60 males, 60 females) completed self-report scales about social anxiety and depression. The participants made responses about their target’s social competence when they were shown the target’s neutral expression either with the target alone or with the presence of two additional observers’ staring at the target. The observers exposed facial expressions of either joyful, angry, neutral or disgust, either for 500 ms or until response. Results showed that the effect of the observer’s emotional expression was proportional to the duration. Especially, when the levels of social anxiety symptoms were high, male participants judged the target to be more competent with the presence of neutral or joyful observers, whereas female participants judged the target to be more incompetent with the presence of angry, disgust or neutral observers. The results indicate that the contextual effects on judgement of social competence depend on the duration of exposure, level of social anxiety, and especially, gender difference.

The objective of this study was to investigate the effect of chronic unpredictable stress on the reproductivefunction and ovarian luteinizing hormone receptor (LHR) expression. 9-week-old C57BL/6 female mice were randomlydivided into two groups: control group and stressed group. Mice have been stressed twice a day for 35 days with12 different stressors which were randomly selected. The results demonstrate that there is significant increase in theanxiety-related behaviors (P < 0.05), decrease body weight gain rate (P < 0.01) and decrease in the average of littersize in stressed mice compared with control group (P < 0.01). Furthermore, the rate of primary, secondary and earlyantral follicles in stressed mice significantly decreased (P < 0.05), whereas that of atretic follicles significantly increasedcompared with control mice (P < 0.01). The immunohistochemical analysis revealed that reduced LHR expression ingranulosa cells of follicle and luteal cells of corpus luteum in response to chronic unpredictable stress. The westernblot analysis revealed significantly decrease in LHR expression in the stressed mice ovaries compared with the control(P < 0.05). These results suggest that ovarian LHR expression affected by chronic unpredictable stress and the modulatedovarian LHR is responsible for ovarian follicular maldevelopment and reproductive dysfunction.

Dictyostelid cellular slime molds were quantitatively isolated from three golf courses in Kyonggi province. The samples were collected in tee, fairway, rough and out of bounds at each golf courses. Dictyostelium muoroides was found at rough of Seo-Seoul C.C and D. minutum at out of hounds of New Korea C.C Compared with other forests, species diversity and species richness appeared to be low. The properties of soils were investigated in three golf courses. This results were very low in water content, organic matter compared with artificial Korean lawngrsss turf in Seoul National University.
