Enzyme electrophoresis was used to estimate genetic diversity and population genetic structure of Pseudobagrus fulvidraco in Korea. Nine of the 14 loci (64.3%) showed detectable polymorphism. Genetic diversity at the population and species levels were 0.286 and 0.277, respectively. Analysis of fixation indices, calculated for all polymorphic loci in each population, showed a substantial deficit of hetero-zygotes relative to Hardy-Weinberg expectations. This deficit is expected that it is due to a limited effective number of individuals per population. The average $G_{ST}$ for polymorphic loci was 0.064, indicating that most (93.6%) of the genetic diversity occurred within populations. The indirect estimate of gene flow based on mean $G_{ST}$ was 3.67. Given limited gene flow is expected to diverge genetically due to drift and reduced populations. Most populations in our study experience annual, severe demo-graphic bottlenecks due to drought and floods.

On the basin of RAPD analysis, genetic diversity and structure of the natural populations of Abies holophylla was estimated by AMOVA procedure. The average value of percent of polymorphic markers was 71.9%. Most variation existed among individuals within population(80.2%). Genetic differentiation among populations(${\Phi}_{ST}$) was 0.198. When the populations were grouped as two region(i.e., Taebaek and Sobaek Mountain Regions), 8.5% of the total genetic variation was explained as regional differences. The heterogeneity of molecular variance among populations was investigated with Bartlett's test, which revealed that populations of Mt. Taebaek and Mt. Gariwang were more heterogeneous. Generally, the populations of Taebaek Mountain Reion were more heterogeneous than those of Sobaek Mountain Reion. Finally, the applicability of AMOVA to the populations frenetic study was discussed in comparison with other measures of genetic differentiation which were widely used.

This study analyzed the the effect of group art therapy on sociality of children in institutional care focus on anger and empathy. The study divided children into two groups, experimental group was treated group art therapy for twice a week(60 minutes, total 25) and control group was treated none. The study results showed that group art therapy had positive impact on improving sociality, anger conrol and emphatic ability of children in institutional care. Also, there had been positive change in their work in the aspect of form and content by HTP, KSD, DAS test. This study found that group art therapy helped improving institutionalized children's socility with anger control and empathic ability, so it is suggested that group art therapy studies for institutionalized children are of help to improve their sociality.

This paper attempts to develop STP Strategy of EXPO 2012 Yeosu for attracting tourists. STP in marketing strategy refers to the process of market segmentation, market targeting, and positioning. I tested four demographic variables(age, occupation, nationality, and sex) to segment the market or the visitors of EXPO 2012 Yeosu effectively. The statistical result shows that age, occupation, and nationality are significant. Based on the three demographic factors and the visitor's purpose, I classified the expected visitors of EXPO into 12 groups, and selected 6 targeted groups: a group of Korean students with the purpose of study, a group of Korean professionals with the purpose of business, a group of foreign students with the purpose of study, a group of foreign professionals with the purpose of business, a group of Korean people in general with the purpose of tourism, and a group of foreign people in general with the purpose of tourism. In this paper, I have suggested a differentiated marketing mix for six targeted groups each.

The purpose of this study was to determine the effects of Enneagram group counseling on clinging and decentering of women in midlife. To determine the effectiveness of the program, pretest, posttest, and follow-up test were performed using Kim's(2006) clinging scale and Kim's(2010) decentering scale in both groups. The collected data were processed by using SPSS/WIN 22.0 to estimate the mean and standard deviation in the pretest and the posttest, with repeated measures ANOVA performed to analyze the effectiveness of the program. This study obtained the following results: First, the enneagram group counseling program was effective in lowering the level of clinging for group participants. Second, the enneagram group counseling program was effective in raising the level of decentering for group participants. These results demonstrate that the enneagram group counseling program is effective in reducing clinging and promoting decentering for group participants.

This study used latent profile analysis to identify heterogeneous subgroups with respect to the perception of work environment among workers in residential facilities for people with disabilities. The final model yielded five latent profiles of the perception of work environment: 'low workload group' who scored low in time pressure and job responsibility, 'discrimination perception group' who scored low in supervisor support and high in sex and academic/regional discriminations, 'positive perception group' who scored high in work autonomy and peer and supervisor supports, 'high workload group' who scored high in workload, time pressure, and job responsibility, and 'average group' who scored average in most areas. In the case of job satisfaction, positive perception group was the highest, followed by average group, low and high workload groups, and discrimination perception group.

The purpose of this study was to develop a group validation therapy(V/T) which could be implemented for the elderly with dementia in nursing home, and to evaluate the effectiveness of the program on cognition, ADL(Activity of Daily Living), depression, problematic behavior and QOL(Quality of Life). Subjects were recruited from 4 nursing homes in D city. The sample comprised forty elderly with dementia, capable of verbal communication. Each twenty were in an experimental and control groups. However, four elders with dementia dropped out in experimental and control groups due to personal affairs. Experimental group completed twelve consecutive group validation therapy sessions that combined centering, asking factual questions, rephrasing, identifying and using the preferred sense, asking the extreme, imagining the opposite, reminiscing, touching, maintaining eye contact and a caring tone of voice, observing, matching and expressing the emotion with emotion, using ambiguity, linking behavior with a basic human need, using music and mirroring techniques. Following the intervention, experimental group experienced a significant improvement in cognition, ADL, depression, and QOL. But it is a nonsignificant in problematic behavior on statistically. As a result, a group validation therapy should be applied as an effective and practical psychosocial intervention for the elderly with dementia.

The aim of this study is to explore the relationships among paranoid tendencies, cognitive characteristics and prejudice. Revised Minnesota Multiphasic Personality Inventory Pa scale, Harris-Lingoes Naivetes(Pa3), dichotomous thinking(DT), attributional style, prejudice toward minority groups(migrant workers, homosexuals, and homeless people) were administered to 557 college students. High Pa3 group was significantly low in prejudice toward minority groups. Also, the group with higher DT showed more prejudice toward minorities. The suggestions and the limitations of this study, and the directions of future study were discussed.

This study examined the differences in facial emotion processing related to psychopathic traits. On the basis of the Psychopathic Personality Inventory-Revised (Lee & Park, 2008), students were divided into psychopathic trait (n=15) and control (n=15) groups. Participants performed two tasks consisted of negative(angry, fear, sad) and neutral faces. Event-related potentials(EPRs) were recorded when participants categorized gender in the implicit task and emotion in the explicit task. We analyzed the late positive potentials(LPP) amplitude to investigate differences in emotion processing between psychopathic trait group and control group. In the implicit task, there was no significant difference in both groups. However, there was a significant interaction between emotion and group at the frontocentral region in the explicit task. The psychopathic trait group showed greater LPP amplitudes for the neutral faces than for the negative faces, whereas the control group showed similar LPP amplitudes for the neutral and negative faces at the frontocentral site. These results might reflect the abnormalities in emotional processing in individuals with psychopathic traits.

The purpose of this study was to find out how Accumulation of Short Duration exercises influence on expression of apoptosis genes in a mouse skeletal muscle. The subjects, ICR-type mice, were divided into three cohorts, Accumulation of Short Duration exercise group, continuous aerobic exercise group, and control group. Accumulation of Short Duration exercise group performed wheel-running for fifteen minutes respectively in the morning and afternoon three times a week. Continuous exercise group performed wheel-running for thirty minutes three times a week. Both split and continuous groups completed the wheel-running trials for sixteen weeks. To identify the difference of apoptosis expression between groups, the data colleted from the skeletal muscle were analysed by one way ANOVA. Analyses of the data revealed that significant differences of apoptosis concentration in both continuous and Accumulation of Short Duration exercise groups, there was a notable differences were observed in control group.
