Recently, youth unemployment, especially the unemployment problem of university graduates, has emerged as a social problem. Unemployment of university graduates is both a pan-national issue and a university-level issue, and each university is making many efforts to increase the employment rate of graduates. In this study, we present a model that predicts employment availability of D-university graduates by utilizing Machine Learning. The variables used were analyzed using up to 138 personal information, admission information, bachelor's information, etc., but in order to reflect them in the future curriculum, only the data after admission works effectively, so by department / student. The proposal was limited to the recommended ability to improve the separate employment rate. In other words, since admission grades are indicators that cannot be improved due to individual efforts after enrollment, they were used to improve the degree of prediction of employment rate. In this research, we implemented a employment prediction model through analysis of the core ability of D-University, which reflects the university's philosophy, goals, human resources awards, etc., and machined the impact of the introduction of a new core ability prediction model on actual employment. Use learning to evaluate. Carried out. It is significant to establish a basis for improving the employment rate by applying the results of future research to the establishment of curriculums by department and guidance for student careers.

The study was designed to grasp the mental health of junior college students and identify the relation between mental health and social support. The subjects for this study were 781 sophomores attending T junior college in Taegu. The data were collected through questionnaire during the period from september 10,1993 to september 24, 1993. The results of this can be summarized as follows: In mental health the average mark was 1.94 on the basis of 5 marks. Those whose mark was more than 75% (low) had Depression(8.7%),Obsessive compulsive reaction(5.2%) Anxiety(3.6%). In social support, the average mark was 3.03 on the basis of 4 marks, which showed comparatively high support; relationship with friends was 75.4%, companionship was 75.4%, and mutual understanding was 72.3%. Many students got more than 75% in total marks. In the state of mental health, there was a significant difference depending on sex, total income, the character and the attitude toward his parents. There is also an unusual difference in social support depending on the major subjects, the character, the problem at present and the attitude toward his parents. In mental health, both male and female students got higher marks in Depression, Obsessive compulsive reaction than in any other item. In social support level all students had a high support in the relationship with friends and mutual understanding. Those who are affectionate to and dependent on their parents had a tendency to have better mental health. The simple correlation modules between social support mark and mental health one was -0.5555 and the partial correlation modules of controlling sex, age, growth place was -0.5557. There was little difference between them. In mental health items Interpersonal sensitivity was highest correlated with social support and Somatinization was lowest correlated. There was a significant correlation between mental health and social support: the higher social support were, the better mental health was. In conclusion, the study showed that the relationship between the social support and the mental health level revealed a significant correlation. In social support Expressive support (companionship support, mutual understanding support) showed a higher degree of support than instrumental support(monetary support, demand support). Therefore, in the guidance of students, it is necessary to expand expressive support considering these respects. Further multidimensional study is needed on how to improve the mental health of junior students through the social support.

Investigations on the contaminated lands due to heavy metals from mining activities or hydrocarbons from oil spillage for example, should be planned based on specific fitness-for-purpose criteria(FFP criteria). A FFP criterion is site specific or varies with situation, based on which not only the data quality but also the decision quality can be determined. The limiting factors on the qualities can be, for example, the total budget for the investigation, regulatory guidance or expert's subjective fitness-for-purpose criterion. This paper deals with planning of investigation methods that can satisfy each suggested FFP criterion based on economic factors and the data quality. To this aim, a probabilistic loss function was applied to derive the cost effective investigation method that balances the measurement uncertainty, which estimates the degree of the data quality, with the decision quality. In addition, investigation planning methods when the objectives of investigations do not lie in the classification of the land but simply in producing the estimation of the mean concentration of the contaminant at the site(e.g. for the use in risk assessment), were also suggested. Furthermore, the efficient allocation of resources between sampling and analysis was also devised. These methods were applied to the two contaminated sites in the UK to test the validity of each method.

This research focuses on what factors determine firm's decisions on R&D outsourcing and how R&D outsourcing affect R&D performance. In recent years many firms outsource R&D activities instead of internalizing it. Thus, further investigation is necessary to find out this recent trend. Based on several theoretical background the study developed three determining factors of R&D outsourcing which are transactional level, firm level, and risk level. Transactional level composes of independent variables such as R&D cost saving, asset specificity and uncertainty which mainly comes from Transaction Cost Economics theory. Firm level composes of openness to technology from outer source, R&D capability, and outsourcing experience. Risk level composes of technological risk, cost-related risk and managerial risk. The result shows that R&D outsourcing is significantly related to cost saving aspect, low asset specific firms, firms without solid technological background, firms which are open to external technology, firms with other types of outsourcing experience, and firms which take technological risks. However, proposed relationship between degree of R&D outsourcing and R&D performance found out to be insignificant. This research is contribute to the field of outsourcing study since it will give guidance to managers who need to make strategic decisions on R&D outsourcing activities.
