Although jobs in the employment service sector have been continuously expanding over the past 20 years, many in the labor market point out that the signaling and selection functions of job counselor qualifications are deteriorating because job counseling and psychology were developed mainly in the early 2000s. Therefore, in this study, a survey was conducted on current employment service workers on the establishment and improvement of employment service professional qualifications. According to the data analysis, employment service workers lack the current level of competence compared to their importance in all their jobs, and there is a limit to taking charge of all the expanded employment service jobs such as corporate support, administrative management, and labor market program planning and execution as a single job counselor. As for the direction of reorganization of employment service-related qualifications in the future, more than half agreed to establish new qualifications. Similarly, more than half of the respondents wanted to strengthen the qualifications of existing job counselors related to employment services.

Objectives: This study is the human factors and disease factors of the copayment system for the elderly (>65 years old) and to identify does the current status and characteristics of the applied elderly and conducted to provide basic data. Methods: Sample cohort data from the National Health Insurance Corporation database, from the years 2012-2015, were analyzed of 21,772 elderly people over the copayment ceiling. Results: The ratio of those who exceeded the copayment ceiling system rose sharply from progressive rates of 3.39% in 2012, 3.69% in 2013 and 5.03% in 2014, to rates of 37.13% from 2013. Factors identified that affect the instances of being over the copayment ceiling were: age, income group, region, severity, disability, sickness distribution, inpatient days, and outpatient days. Conclusions: The reorganization of the copayment ceiling system in 2014 favored low-income families of the elderly, but in 2015, the proportion of elderly was low (only 5.78%). The government's policies needs to change to allow for the amount of the deductible upper limit for low- and middle- income groups to be further subdivided in order for the elderly to receive more deductibles.

Syndecans, transmembrane heparan sulfate proteoglycans, are coreceptors with integrin in cell adhesion process. It forms a ternary signaling complex with protein kinase C and phosphatidylinositol 4,5 bisphosphate (PIP2) for integrin signaling. NMR data indicates that cytoplasmic domain of syndecan-4 (4L) undergoes a conformational transition in the presence of PIP2, forming oligomeric conformation. The structure based on NMR data demonstrated that syndecan-4L itself forms a compact intertwined symmetric dimer with an unusual clamp shape for residues Leu$^{186}$ -Ala$^{195}$ . The molecular surface of the syndecan-4L dimer is highly positively charged. In addition, no inter-subunit NOEs in membrane proximal amino acid resides (Cl region) has been observed, demonstrating that the Cl region is mostly unstructured in syndecan-4L dimmer. However, the complex structure in the presence of PIP2 induced a high order multimeric conformation in solution. In addition, phosphorylation of cytoplasmic domain induces conformational change of syndecan-4, resulting inhibition of PKC signaling. The NMR structural data strongly suggest that PIP2 promotes oligomerization of syndecan-4 cytoplasmic domain for PKC activation and further induces structural reorganization of syndecan for mediating signaling network in cell adhesion procedure.

This thesis introduce the organization system and office regulation of standardization administrative organization for the change of times, also suggest improvement plan for its effective management. The main improvement plan refer to the standardization administrative organization\`s work, this thesis suggest, 1. Readjustment of national standardization system and effective reorganization for standards information organization. 2. For industrial standards system, the korea industrial standards should be maintained uniform system, So decentralized korea industrial standard at government ,must be unified and maintained to unique policy for its effective improvement. 3. To strengthen with international standards organization, a institutional device, budget funds, and expert should be backed up. 4. For training and education of expert, Refer to the performance of one\`s duty, the proper expert should be chosen and posted. Also, systematic training and education system for expert must be developed, So they can be on duty continuously, Finally, this thesis suggest that the necessity of systematic and unique policy must be established for high position at international area. Since the limitation of data, the future research will be performed for budget funds and personnel setup.

Artifical Neural Network(ANN) models were used for forecasting interest rate as a new methodology, which has proven itself successful in financial domain. This research intended to construct ANN models which can maximize the performance of prediction, regarding Corporate Bond Yield (CBY) as interest rate. Synergistic Market Analysis (SMA) was applied to the construction of models [Freedman et al.]. In this aspect, while the models which consist of only time series data for corporate bond yield were devloped, the other models generated through conjunction and reorganization of fundamental variables and market variables were developed. Every model was constructed to predict 1,6, and 12 months after and we obtained 9 ANN models for interest rate forecasting. Multi-layer perceptron networks using backpropagation algorithm showed good performance in the prediction for 1 and 6 months after.

Japanese railroad companies continued growing by developing diversification based on the railroad enterprise. However, the diversification strategy of railroad companies reached the management limit in the 1990s. Under the long-term economic depression, Aging and a decrease in the birthrate progressed and passenger transport changed to the downward tendency. Nevertheless, since railroad investment was expanded, business results worsen and price competitiveness with JR East became weak. Futhermore, the business results of a diversification enterprise were bad compared with it of a railroad enterprise. Therefore, group management was thought as important and structural reform was carried out resolutely.

Financial ratio indicators of the 46 sample hospitals provided by the Korea Health Industry Development Institute, together with the survey data responded by the 57 sample hospitals, were analysed to identify the characteristics of the red-figured hospitals' financial structure, financial operational efficiency and management decision-making behavior, The financial characteristics identified through the analysis include high dependency to liabilities, high salary expenses and overhead costs, low profitability of the unduly large amount of fixed assets, and low managerial efficieny of inventory. The hospitals, in face of the IMF economic impasse, took the necessary decision-making and counter measures to cut down salary expenses, to increase the number of patient and medical revenue, and to reduce investment to fixed assets. Based on these findings this study suggested that the hospitals should take more active cost containment measures, financial structural reorganization, and developoment of the strategies that can contribute to increase of the number of patient and medical revenue and that do not. require much capital funds.
