The purpose of this study was to investigate the relationship between career barrier and career maturity of the adolescents who were concretely worried about their career and occupation. 672 middle school students were participated to analyze the Pearson Correlation and Multiple Regression Analyses with data collected by the questionnaire. This study revealed the following results. First, the correlational analysis showed that career barrier associated negatively with career maturity. Second, the multiple regression analysis revealed that sub-elements of career barrier which the adolescents conceived, such as the shortage of self-understanding, the shortage of self-reliance, gender-role conflict and gender discrimination, and the shortage of career and occupational information were significantly effecting their career maturity. Third, as a result of multiple regression analysis to estimate the explanability of career barrier on career maturity, career barrier among various independent factors which were correlated statistically with career maturity showed most effects on it. Also, school academic achievement was confirmed as a significant factor effecting the career maturity. Above these results imply that the perception on the career barrier of the adolescent should be reduced for increasing the career maturity. For this, career education and counselling should be positively intervened and reinforced through the school curriculum and activities.

Objectives : The definition of a hidden youth is a young person who has completely withdrawn from society and shut himself or herself away for more than 3 months. Those pathologically-withdrawn youths have become a burden not only to society but also to the family. However, screening of these hidden youths cannot be done easily. This study focused on developing a primary effective screening tool for these hidden youths. Methods : The 42 participants of this study were parents of hidden youths that are between 8 to 25 years old. They were selected from from mental health centers and psychiatric clinics around Seoul and Gyeonggi Province. We also recruited 239 parents of middle and high school students in the Seoul metropolitan area for a control group. In order to decide the concurrent validity of this questionnaire, we used the Symptom Checklist-90-Revision, Children's Depression Inventory, Beck Depression Inven-tory, Social Anxiety Scale for Children-Revised, Social Anxiety and Distress Scale, Avoidant Personality Disorder Scale, and State-Trait Anxiety Inventory for Children. SPSS version 12.0 was used for statistical analysis. Results : Cronbach's alpha values, the reliability coefficient to represent internal consistency, were between 0.396 and 0.935, which showed relatively high internal consistency for this questionnaire. The test-retest coefficient was between 0.68 and 0.78, which was a statistically significant result. In a factor analysis, 4 factors such as avoidance, withdrawal, isolation, and apathy were extracted. In a concurrent validity test with SCL-90-R, the isolation factor showed a statistically-significant relationship with a phobic-anxiety sub-scale, and avoidance and withdrawal sub-scales were remarkably correlated with the interpersonal sensitivity sub-scale. Conclusion : Since the questionnaire for socially withdrawn youths has achieved statistically-satisfactory reliability and validity, it will be a useful method to screen for hidden youths in educational, community, and clinical settings.

The informatics computer teacher appointment examination is the only national test to measure the competence of educators in teaching students relevant informatics content. The purpose of this study is to provide suggestions and directions for improvement of the informatics computer teacher appointment exam. To this end, we collected appointment exam questions from 2002, when the informatics computer teacher appointment exam first started, to 2017. Based on evaluation areas and evaluation content factors of the indication subject of informatics computer, we built the analysis framework and criteria used in this study. The analysis took into account the revision of basic required courses and changes in the types of exam questions. We analyzed the percentage of points allotted to the subject matter compared to the total number of points, and also the trends of exam questions by school year. The results of the analysis are as follows: first, improvements should be made to avoid concentration in certain areas of the basic required courses of the informatics computer subject. Second, the discrepancy between the exam and the curriculum of basic required courses must be addressed to properly teach and evaluate preliminary teachers. It is significant that this study serves as a stepping stone in supplying highly competent teachers to the field through improving the informatics computer teacher appointment examination.
Currently mobile messenger industry, based on mobile application, is growing. And it has aroused innovative change, offering services in various forms beyond the form simply sharing messengers. Also because messenger securities are becoming personalized and intelligent, the importance of more diverse mobile applications' securities is increasing.

The path analysis results are as follows. First, perceived autonomy has a positive effect on both security awareness and security intention. Second, perceived competence has a positive effect on security intention. Third, perceived relatedness has a positive effect on both security awareness and security intention. Last, security awareness and security intention. have a positive effect on privacy protection behavior. Through emphasizing the importance of the security of the messenger of individuals and contribute to a positive role for development of the necessary security guidelines to consumers.
Objectives : 'First-night effect' has been a well-known concept since 1960's. It is important because it is one of the major factors to be considered in assessing the reliability of polysomnographic data. However, 'reverse first-night effect' has also been described, resulting in the inconsistency of conceptualization. We attempted to investigate on the first-night effect in adults by having each of them take two nights of polysomnography in a controlled environment. Young healthy adult volunteers were chosen as subjects in order to rule out age- or health-related confounders. Methods : Polysomnography was performed on eight male medical students (mean $age=23.5\;{\pm}\;0.9$) for two nights with Grass model 78 polysomnograph. We scored manually under the standard protocol each epoch of the sleep records. Sleep variables were obtained and compared between the two nights. Results : Sleep period time(SPT) and total sleep time(TST) of the third fraction of night were significantly longer on the first night than on the second night (p<0.05). However, other sleep variables such as percentage of each sleep stage, sleep latency, REM sleep latency, number of waking, and sleep efficiency were not different between the two nights. Conclusion : We could not confirm the existence of first-night effect in this study. In healthy young male adults, it may not happen at all or may happen to a very negligible degree. Young healthy adults may have more adaptability to a new sleep environment. Also, the provision of a reasonably comfortable sleep environment could have helped them with abolition of first-night effect.
This study was to find out the effect of emotional maltreatment by parents on revictimization of emotional maltreatment by peers targeting second-year students of middle school with depression and social withdrawal as mediating variables. To this end, those who experienced physical violence by parents or friends were excepted from panel data collected by National Youth Policy Institute (KCYPS) and data of 752 people who experienced emotional maltreatment by parents or peers were analyzed. Research hypotheses were verified by a utilizing structural equation model. The results can be summarized as follows: First, experiencing emotional maltreatment by parents has a direct impact on depression and social withdrawal. Second, it was found that depression has a direct impact on experiencing emotional maltreatment by peers while social withdrawal is significant in an indirect path affecting with depression as a mediating variable. Third, the multiple mediated effects of depression and social withdrawal were significant in the revictimization relationship between emotional maltreatment by parents and emotional maltreatment by peers. This means that emotional maltreatment by parents becomes a predictor in re-experiencing emotional maltreatment by peers. It also means that emotional maltreatment by parents has an indirect effect through psychological and emotional factors such as depression and social withdrawal rather than having a direct effect. Based on the results of this study, limitations of the study and suggestions for future research were discussed.

Cultivation of competent manpower is recognized as one of the important factors in the development of fisheries as well as of other industries. For reference to the development of education of fisheries high schools in the Republic of Korea, the author carried out a study on the education in Japan. The reason is why the education on fisheries had been initiated in Japan and her educational system has played the role of a model for neighboring countries. Even though the education on fisheries tends to shrink a little in recent years by diffusing the unwilling tendency to engage in 3D (dirty, difficult and dangerous) jobs, there are fifty-one high schools educating fisheries in Japan. Thirty-eight of them are specialized fisheries high schools and the others are comprehensive high schools to put common course and fisheries course together. In the first step of study, the goal of education on fisheries, organization of department and arrangement of curriculum are analysed. 1. In the newly arranged curriculum which will come into effect from 1994, the goal of education on fisheries is set up as "By educating fundamental knowledge and technology on the production and circulation in the field of fisheries, have students understand the significance and role of fisheries, and so cultivate ability and active attitude to the development of fisheries". The goal means that the circulation of fishery products are regarded as important as the production itself, and active attitude to the development of fisheries is also stressed, different from the present goal. 2. Standard departments directed by the Government are set up as five-Departments of Marine Fishing, of Fisheries Engineering, of Information Communication, of Fish Culture, of Sea Foods. But they are actually organized and named by the founders of schools-local government. Then there are many unique-named departments and the management of schools are somewhat flexible according to the situation of local district. 3. Special subjects are revised to twenty-four in the new curriculum from twenty-two in the present curriculum. Among them the contents are widely revised in the subjects such as Introduction to Fisheries, Fisheries Engineering, Communication Engineering, Communication Technology, Fish Culture. On the other hand, five subjects such as Information Treatment on Fisheries, Information Technology on Fisheries, Subjective Study, Fisheries Economics, Circulation of Sea Foods are newly set up to meet the changing phase of the time.
Panax ginseng C. A. Meyer, which has been known for more than EWO years. occupies a Particular prince in folk medicine as so called tonic remedy. The pharmacolgical investigations of ginseng, based on the scientific concepts and methodology, have been performed by many researchers through the past 50∼60 years at different parts of the world. The pharmacological action of Panax ginseng compiled from the numerous reports can be summarized as follows: 1. On central nervous system, the effect of Panax ginseng is timulatory in smaller doses and somewhat depressive in larger doses. From the psychopharmacological aspect, ginseng seems to increase the mental efficiency of man. 2. Ginseng has the effect tending to Protect organism from various physical and chemical stresses. 3. The growth and basal metabolic rates of experimental animals are stimulated by ginseng. Ginseng also prolongs the survival time of animals under adverse influences. 4. Increasing the physical and mental efficiency, ginseng postpones the onset of fatigue and increases the working capacities. 5. In the case of the intravenous administration of ginseng, a transitory and slight hypotensive effect is observed. These hypotensive effects seems to include that of a direct action and actions related to the release of histamine and/or serotonin by ginseng. 6. It is Presumed that ginseng lowers the elevated bleed ingar and cholesterol level. 7. Ginseng tends to increase the gastrointestinal motizity and tone 8. It is presumed that ginseng Promotes the iron metabolism and activates the hematopoietic factors. 9. Ginseng tends to stimulate the biosynthesis of nucleic acid and release of histamine and serotonin. 10. The toxicity end adverse reactions of ginseng appear to be nothing that warrants apprehension. 11. Anticancer erects of ginseng seem to be due to indirect action rather than direct action on cancer cell, by improving the host condition 12. Recent clinical trials of ginseng harts obtained sent good results, but Present trial is still limited in its range, so it is necessary to broaden the scope of trial covering many kinds of organs and diseases. From the above, although it appears that substantial advancements have been achieved in the studies on the Pharmacological actions of Panax ginseng there are many discrepancies noticed in the reported data. Furthermore the precise mechanisms of actions of ginseng are sometimes obscure, even unknown in other actions as the students stand now. The main reasons for this are considered to be that even though saponin has been identified at one of the active substances of ginseng, other components have not fully been identified and that the experimental approaches of the investigations varied with different researchers. Thus a thorough analysis of the chemical components and newer standardized concepts and metohds appear to be the pre-requisites for further study of the pharmacolgical effects and mechaisms of Panax ginseng.
The purpose of this study was to investigate the effects of p. Linteus and C. militaris supplement on lactate, phosphorous, ammonia, MDA(malondialdehyde), GPX(glutathione peroxidase) and TAS(total antioxidant status) following $VO_{2max}$, and 85% $VO_{2max}$ exercise. The 15 male college students were divided into three groups: 5 P. liteus supplied(PL), 5 C. militaris supplied(CM), and 5 placebos supplied(PB) and compared the differences between supplement before and after. Obtained results were as follows: In the exercise performance time, there were no differences in PL, CM and PB groups. Regular supplement of P. linteus or C. militaris partially reduces fatigue induction factors. Also, P. linteus or C. militaris supplement decreases MDA, increases GPX and TAS. Therefore, it can be concluded that P. linteus or C. militaris supplement not only have a pharmacological effect for clinical treatment, but also have a maintenance effects on the tissue oxidant-antioxidant system after exercise.

The purpose of this study was to investigate the influence of temperament and stress coping strategies on adolescents' psychological well-being. Three hundred and ninety nine middle and high school students in Seoul participated in this study. Temperament, stress coping strategies, and psychological well-being were evaluated by self-report questionnaires. Data were analyzed using Cronbach's alpha, frequencies, percentiles, means, standard deviations, two-way ANOVAs, Pearson's correlations and hierarchical multiple regression analyses. The results were as follows: First, there were significant differences in psychological well-being as a function of gender and school levels. Second, temperament and stress coping strategies were related to psychological well-being in adolescents. In the sub factor of temperament, activity and persistency were positively associated with psychological well-being, whereas rigidity was negatively related to psychological well-being. Among stress coping strategies, problem-focused strategy was positively associated with psychological well-being, whereas emotion-discharge strategy and affective-regulation strategy were negatively related to psychological well-being. Third, hierarchical multiple regression revealed that problem-focused strategy and emotion-discharge strategy were influential factors in explaining the level of psychological well-being controlling for gender, school levels and temperament of the adolescents. These findings suggest that stress coping strategy should be considered to promote the level of psychological well-being of adolescents.
