The size of state in Korea is like Israel, this country's venture capital is ruled by government. This venture capital's character is below: the concentration on research of venturer affect positively at quality of products. This paper lies with venture capital's risk character & performance. The results show that Korean venture capitals have lager unsystematic risk than systematic risk, which implies they specialize in specific business and/or regional areas instead of diversification. The Sharpe & Jensen measures reveal that the performances of Korean venture capitals are very low relative to even the market portfolio(Kospi) and Kosdaq Venture Index. Contrary to this, Venture firm's performance according to Entrepreneurship will cause to push up stock price.

Objectives : The aim of this study was to clarify the role of alcohol use disorders and acute alcohol consumption in suicide attempts by gender. Methods : Data of 1,152 suicide attempters(487 males and 742 females) who had visited an emergency center was gathered. Suicide attempts were categorized into three groups according to alcohol use: an alcohol use disorder group(AUD), an acute alcohol use group(AAU), and a no-alcohol use group(NAU). The intent and lethality of suicide attempts were evaluated by Suicidal Intents Scale and Risk-Rescue Rating Scale. Results : For Suicidal Intents Scale score, the male AUD group revealed a significantly lower mean score than the male AAU one. However, there were no statistically significant differences for female subjects across subgroups. With regard to the Risk-Rescue Rating Scale score, there were no significant differences for males, while the AUD group showed both the lowest highest rescue scores and lowest risk-rescue scores within female groups. Conclusions : AUD in females was more likely regarding impulsive suicide attempts with high rescue chances. Consuming alcohol might have different effect on suicide attempts by gender and our study shows that alcohol use is an important risk factor according to gender, particularly with regard to female suicide attempts.

This study is intended to come up with the Scale of the danger in the adolescents' school-dropout. The present dissertation developed the questions and collected them on the base of the potential variables, that consist of the school-dropout of adolescents, and the operational definition of each variable, through the verification of the precedent research and the review of the related literatures. In addition, the interviews for the teachers who have experienced the school-dropouts of adolescents are performed and are analyzed, and then the relevant questions were culled. The Scale developed in this study is composed of 48 questions and 10 factors. The questions which have the same factors and clustered are reflected, and then are discerned into 3 dimensions, that is, the outer attitude, the inner attitude, and the attitude of parents. The Scale of the danger in the adolescents' school-dropout which is contrived through this study is expected to prevent school-dropouts to teenagers and the teachers.

As the radiation is used in various fields, the number of radiation workers is on the increase and there has been an increasa in interest in the radiation worker's safety. In South Korea, it is focusing on securing safety of workers through KISOE system and owner's report. In advance study, We determined that in assessing the risks of securing safety for workers and businesses, the assessment of other items as well as exposure doses would be effective and develops the Radial Scale Analysis Model. So, data from the actual radiographic testing companies were applied to the radial scale analysis model to determine the risks of the actual companies. And, we selected 4 companies to confirm the applicability. Risk assessments of all 56 companies were conducted and improvements and inspections were anticipated for each company's problems. The results of the study are expected to be utilized by radiographic testing companies and regulatory for self-assessment and regulation criteria.

The objectives of the present study were to provide comprehensive assessment of the impact of epilepsy on the psychological well-being of children with epilepsy and to identify the neurological factors associated with the psychopathology. The participant patients were recruited from the population of children and adolescent aged 7 to 16 attending the OPD of department of pediatric neurology in Seoul National University Hospital in Korea. We exclude mental retardation, pervasive developmental disorder and brain organic pathology. As control group, formal students were chosen and their sex, age, achievement, socioeconomic status were matched to patients. The first author interviewed the children and their family members and obtained the developmental history and family information. We used the following 10 scales for assessing psychological and behavioral problems in patients and their family member. The scales were standardized and their validity and reliability were confirmed before. Parent rating scales : Yale children's inventory, Disruptive behavior disorder scale, Parent's attitude to epilepsy questionnaire, Family environment scale, Symptom check-list-90 revision, Children behavior check-list. Children's self rating scales : Children's depression inventory, Spielberger's state-trait anxiety anxiety, Piers-Harris self-concept inventory and Self-administered Dependency questionnaire for Mother. The result showed the risk factors associated depression were early onset, complex partial seizure, lateralized temporal focal abnormality on EEG, Drug polypharmacy, high seizure frequency and sick factors associated anxiety were old age of patient, lateralized temporal focal abnormality EEG, Drug polypharmacy, high seizure frequency. Also the result of this present study indicated that risk factors associated oppositional defiant disorder, conduct disorder and attention deficit hyperactivity disorder were young age, male, early onset, lateral temporal EEG abnormality and high seizure frequency. According to these results, common risk factors associated psychological and behavioral problems were lateralized EEG temporal abnormality, high seizure frequency in neurological factors.

Objectives：The primary purpose of this study is to understand the psychopathology of the victims of school violence in terms of early psychosis. By doing this, the early detection of psychosis among the victims is possible, and early detection may lead to early intervention. Methods：Two-thousand and nine-hundred seventy two students from 16 middle schools in Seoul were asked to fill out questionnaire comprised of popularity and intellectual and school status of Piers-Harris Children's Self Concept Inventory, Symptom Check List-90-Revised, and Ostracism Scale. The subjects whose scores upon Ostracism Scale were higher than average by two standard deviation were labeled as ‘Repelled and Isolated group', and subjects whose scores on popularity were significantly lower than average and whose scores on psychoticism of SCL-90-R were higher than average were defined as 'tentative early psychosis group'. Odds ratios were calculated from the numbers of subjects with and without high psychoticism scores and high ostracism scores. On the subjects of 'tentative early psychotic group', we examined every clinical characteristic and conducted correlation analysis and regression analysis in order to find out the risk factors and to construct theoretical model that explains the psychoticism scores. Results：The results were as follows：1) Total 157(5.3%) subjects were rated significantly higher on ostracism scale, and among them, 47 subjects(29.9%) were rated significantly higher than average on psychoticism scale, while only 50 subjects among 2,135 students who were rated within normal range showed significantly higher score on psychoticism scale. Odds ratio for psychotic group of isolated group were 17.82 and it was statistically significant. 2) Forty-seven subjects(31 boys, 16 girls) who were rated as they were unpopular and rejected from peers had significantly higher psychoticism scores. They were not significantly different from simply high psychoticism subjects in anxiety, social anhedonia scale, magical thinking, obsessivecompulsive symptoms, phobic anxiety, psychoticism, somatization, but showed higher ostracism scores and paranoid tendencies. Among school violence victims, who rated themselves unpopular and showed higher psychoticism scores, the psychoticism scores were mainly explained by anxiety, depression, hostility, interpersonal sensitivity, obsessive-compulsive symptoms, paranoid tendency, somatization scales($r^2=0.93$). Conclusion：Thus, it can be concluded that the subjects with higher ostracism score have the substantially high risk for psychosis development. By these results, we propose that school violence victims with anxiety, depression, hostility, interpersonal sensitivity, obsessive-compulsive symptoms, paranoid tendency, somatization should be tested individually considering school adjustment, attentional deficit, concept formation problems.

This study was conducted to investigate the reliability and validity of the Korean self-compassion scale using data from 312 correctional workers. To validate the self-compassion scale using the collected data, correlational analysis, exploratory and confirmatory factor analysis were applied. To explore relationships between the self-compassion scale and related instruments, five instruments were used (the Korean occupational stress scale, the center for epidemiological studies depression scale, the Maslach burnout inventory scale, perceived stress scale, and the satisfaction with life scale). The results showed that the collected data better fit the 6-factor model than the 3-factor and 2-factor models. There were statistically significant relationships between the self-compassion scale and five other scales. These results suggest that the self-compassion scale is a good instrument to examine risk factors that can remain during continuous stress situations and to explore protective factors that can maintain the therapeutic relationship. The implications of this study and future research directions were also discussed.

The purpose of this study was to examine the effects of thoracic flexibility exercise on sitting balance, static standing balance, gait parameters, and the fall risk of patients with chronic stroke. The participants were randomized into the control (n=12) and thoracic flexibility exercise groups (n=12). Both groups received standard rehabilitation therapy for 30 minutes per session. The subjects in the experimental group performed additional thoracic flexibility exercises 3 times a week for 6 weeks. The trunk impairment scale, static standing balance, gait speed, cadence, and fall risk were assessed for all the participants before and after the intervention. The thoracic flexibility exercise group showed greater improvement than did the control group on the trunk impairment scale (t=-3.57, p=.002), static standing balance (t=5.37, p<.001), gait speed (t=-3.29, p=.003), cadence (t=-2.77, p=.011), and fall risk (t=6.33, p<.001). Furthermore, the thoracic flexibility exercise group significantly improved all the outcomes compared to the baseline values (P<.05). This study showed that the thoracic flexibility exercise improved the functional ability of patients with chronic stroke.
