The study applied chemistry classes based on Collaborative Problem-Solving for Competency(CoProC) Instruction Model to 86 high school seniors and recognized the resulting changes in Character Competence through character competence test, analysis of argumentation, and analysis of reflective writing. In addition, the analysis of the correlation between the assessment results showed what each evaluation method meant to assess Character Competence. The study found that the average score of Character Competence rose in all three assessments, but differences were found in the detailed factors. Character competency test is meaningful in helping students participate with a sense of mastery of learning as a self-evaluation, and the analysis of the argumentation process seems to be an appropriate evaluation method to evaluate the Character Competence shown by students' words and actions through course evaluations. An analysis of reflective writing showed the advantage of being able to analyze Character competencies that are difficult to show in action by looking back on the entire course of learning. In addition, given that the correlation between the three assessment results is very low, it is expected that the three Character competency assessment methods will be conducted together to obtain detailed and comprehensive information on students' character competencies.

Objectives : Significant progress has been made in understanding psychosocial, psychological, and environmental factors associated with suicide. However it is only recently that attention has been paid to the understanding of the neurobiology of suicide. The aim of this study was to examine the relationship between platelet serotonin level and suicidal behavior and psychological features of the suicidal attempters. Methods : After a suicidal attempt platelet serotonin level was measured from 21 patients and compared it with those from depression patients and normal controls. Also MMPI, HAM-D, Barratt impulsiveness scale(BIS) were done to evaluate their psychological features. Results : 1) There was no significant difference in sex ratio of the suicidal attempters. 2) There was no significant difference in platelet serotonin levels among three groups. 3) The analysis of MMPI revealed that the scores of D, Hs, Pt in clinical scales were significantly higher in suicide patients and scores of D, Pa, Si were in depression patients. 4) The HAM-D score was significantly higher in depression and suicide patients, especially in depression patients. 5) The analysis of Barratt impulsiveness scale revealed that the scores of nonplanning, motor and cognitive impulsiveness scale were significantly higher in suicide patients. Conclusions : There was no significant difference in platelet serotonin levels among three groups. However the analysis of psychological features revealed significant differences. Therefore we concluded that psychological examinations are benefit to evaluate the suicidal tendency.

Objectives: This study investigated the psychological characteristics of patients with functional dyspepsia. Methods: The subjects included ninety patients with functional dyspepsia and sixty four psychiatric out-patients. We administered Minnesota Multiphasic Personality Inventory(MMPI) and Illness Behavior Questionnaire(IBQ). Results: There were no significant differences between the patients with functional dyspepsia and the psychiatric out-patients by MMPI. Two groups both showed a higher distribution in hypochondriasis, depression, hysteria subscales than in any other subscales. The patients with functional dyspepsia showed lower scores in disease conviction and affective disturbance subscales in IBQ than the psychiatric out-patients. The distribution of scores of the other IBQ subscales were similar between the patients with functional dyspepsia and the psychiatric out-patients. The patients with functional dyspepsia were divided into three groups for the Multivariate cluster analysis: normal, similar to psychiatric out-patient, and severe neurotic. The severe neurotic group showed higher scores in hypochondriasis, depression, hysteria, psychathenia, and schizophrenia subscales in MMPI and showed significant different scores in affective disturbance, disease conviction, psychological and somatic concerns, affective disturbance, denial, and irritability subscales in IBQ. Conclusion: If patients with functional dyspepsia show severe neurotic behavior, such as those in, they would need appropriate psychiatric intervention.

복무적합도 검사는 정신질환이나 사고가능성이 있는 병사를 감별하고, 입대 후 적응문제로 조기 전역할 수 있는 집단을 예측하는 신인성검사 중 하나로, 현재 군에서 징병 및 입영단계에 실시하는 인성검사이다. 이는 전체 검사대상자를 상대로 정신과적 문제 식별을 위한 개별면담이 불가능하기 때문에 위 검사를 통해 대상자를 효율적으로 선별하기 위함이다. 본 연구는 데이터 마이닝을 통해 복무적합도 검사의 판정을 예측 할 수 있을지 확인하고자 하였다. 이를 위해 데이터 마이닝의 기법 중 회귀분석의 로지스틱 회귀분석 기법이 복무적합도검사 판정에 우수한 성능을 보임을 확인하였고, 로지스틱 회귀분석의 추정된 회귀계수를 이용하여 만든 반응확률에 대한 예측 모형식은 높은 정분류율을 보였고 평가 결과 통계적으로 의미가 있음을 증명하였다. 따라서 본 연구 결과를 활용하면 소수의 문항으로 복무적합도 검사 이전의 선별용 검사 개발이나 자가 진단용 검사 개발로 활용이 가능 할 것으로 기대한다.

Impact behavior of carbon fiber reinforced plastics (CFRP) laminates were evaluated with tension test and compact tension test. A steel ball launched by an air gun collides against CFRP laminates to generate impact damage of relatively low energy. The static tensile and fracture toughness tests were performed to evaluate the residual strength and the AE behavior of impact-damaged laminates. As a results, it was found that the static strength, the fracture toughness and the AE-event count were decreased with increasing of impact velocity and delamination area, and to have a different strength ratio and fracture toughness ratio for each stacking method. And also, it was confirmed that strength and fracture toughness of impact-damaged CFRP laminates could be evaluated and analyzed quantitatively by AE techniques.

The study on correlation between the parents' character of orthodontic patients and patients cooperation. Although dentists have excellent skill and technique, patients' cooperation is always demanded. Patients' poor cooperation results in poor treatment result. Cooperation between psycho-social state of parents and patient's cooperation was studied. The parent's psychosocial state is evaluated with scl-90-r. The cooperation is measured by appointment time compliance, appliance taking rate, breakage of appliance, and fee paying. Parents' psychosocial contents are somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic-anxiety, paranoid ideation, psychoticism, and additional item. Statistics was done by SPSS WINDOW version 12.0 program. The result showed no correlation between patients' cooperation and their parents' psychosocial state. There is no correlation between father's psychosocial state and patients' cooperation except psychoticism. There is no correlation between mother's psychosocial state and patients' cooperation. However, there was correlation among cooperation variables: appointment time compliance, appliance taking rate, breakage of appliance, cost paying. Appliance taking rate and cost paying showed positive correlation. Our findings suggest that patients' cooperation does not followed their parents' pychosocial state. Other combined factors should be considered like pychosocial state of patient and doctor-patient relationship.

The purpose of this study is to investigate the effect of science classes using elementary school distance science classes on science academic achievement and creative personality. The research group and non-research group were selected for 6th grade elementary school students. After 10 weeks of experimental treatment, science classes were conducted with the contents of the elementary school science section, 'Changes of the seasons'. In the three domains of 'knowledge', 'inquiry', and 'attitude', which are sub-domains of science academic achievement, as a result of the pre-post test, there was a positive effect in 'inquiry' and 'attitude', which are sub-domains of science academic achievement. However, it was found that there was no positive effect in 'knowledge', a sub-domain of academic achievement. However, it was found that there was a positive effect in the overall test result of academic achievement. Therefore, it is interpreted that science classes using elementary school distance science classes had an effect on academic achievement. There was a significant effect in the sub-domains of the creative personality test, 'persistence/obsession', 'self-confidence', 'humor', 'imagination', 'openness', 'adventure', and 'independence'. However, it was found that there was no effect in the sub-domain 'curiosity'. The overall test results of the creative personality test showed a significant effect. Therefore, it is interpreted that science classes using elementary school distance science classes are effective in cultivating creative personality. Students' perceptions of science classes using elementary school distance science classes also showed positive responses.

The purpose of this study is to explore the occupational personality required for high school graduates and to develop a scale to measure them objectively. In order to achieve the purpose of the study, this study constituted the delphi committee composed of the teacher group and the industrial personnel group. Afterwards, Delphi survey was conducted twice, and it was found that 12 jobs such as sincerity and honesty were related to occupational personality. As a result of the development of the scale based on the previous research and the expert group interview, 12 factors and 116 scales were developed for the pre - occupational personality test tool. In order to verify the validity and reliability of the developed preliminary test tool, we conducted a questionnaire survey of 700 students of vocational high school, and 514 questionnaires were used for final analysis. Parallel analysis was performed to determine the number of factors before exploratory factor analysis. As a result, eight factors were found to be appropriate. As a result of exploratory factor analysis using the 'maximum likelihood method' and 'direct oblimin rotation method', 78 items of 8 factors were found appropriate. However, in order to confirm whether the item reflects the contents of the factors, we conducted a content validity test for the expert group. As a result, feedback was obtained that 19 items were irrelevant or inadequate. Therefore, the validity of the existing job personality test tool and the modified job personality test tool were verified through confirmatory factor analysis. As a result, the fitness of the revised test tool was higher and the fitness level was generally good.
