Age-related osteopenia and osteoporosis are common in postmenopausal women due to decrease in bone mass and ovarian function. A therapy for osteoporosis would depend on only drugs to inhibit bone loss, hormonal replacement therapy, exercise and dietary supplementation and it is very hard to fad an ideal therapy for osteoporosis as yet. Chlorella which is rich in minerals such as calcium magnesium fatty acids, vitamins and sterol, could be applicable for prevention and co-treatment of osteoporosis, but it has yet to be studied. The purpose of this study was to assess the relationship between the effect of dietary chlorella on bone mineral density (BMD) and nutritional improvement. BMD was measured in the femural neck and lumber spine portion. Nutritional and bone turnover markers from blood samples were assessed serum lkaline phosphatase, hemoglobin, number of erythrocytes and total protein. Studies for the femur neck measurement showed that normal BMD increased 2.1% for the group fed chlorella supplemented diet for four month and increased 6.6% fur group treated for one year when compared to the control group, and for the lumber spine measurements the few month group showed an increase of 9.1% over the control group, the one year group showed an increase of 64.2% over the control group. Hemoglobin content, number of erythrocytes and total protein showed similar increased patterns with BMD measurement, meanwhile, serum alkaline phosphatase increased 3% for the four month group and decrease 16% for the one year group compare to the control group. In conclusion, the postmenopausal women fed chlorella supplemented diet results in an increase in BMD. This is a marked increment in lumber spine, enhancement of nutritional state and stable bone turnover. This data showed a positive relationship between BMD and nutritional change with chlorella treatment, and suggested that chlorella dietary may lead to improving and preventing rapid loss of BMD in postmenopausal women.

In this study, parallel work-learning training, which was started in 2013 as a pre-employment promotion policy, is an important factor that determines the success or failure of training. As a time when various institutional supplementation is needed to encourage company participation, this study is to identify the factors of participation of companies participating in work-learning parallel. To this end, a questionnaire survey was conducted of companies participating in parallel work-learning in Chungnam, and the results were analyzed using the structural equation model. As a result of the study, the reason for the company's participation in parallel work-learning was firstly, 84% of government subsidy received education and training expenses. Second, 66% of workers were able to pay less than regular workers, and thirdly, it was easy to hire new employees in the field. 26%, 17% of them were invited by acquaintances for no particular reason. Therefore, the study suggests that participation in the work-learning parallel training contributes to the management costs, management of employee turnover, and human resource development. In future research, it is necessary to subdivide tests and estimates by conducting studies on regions, occupations, gender, wages, and years of service in Korea.

The present study examined the impact of work stress and job satisfaction on intention to leave among staff including social workers, nurses, and care workers. The study subject included 235 staff in a welfare organization that provides long-term care services. Data was analyzed using multiple linear regression. The findings of the study show that work stress and job satisfaction affect intention to leave in the context of welfare organizations. Demographic variables were not the main focus of this study and thus these results are incidental. Staff with higher levels of work stress were more likely to think about leaving, while those with grater job satisfaction were less likely. There were several limitations in this study. Generalizability of the findings are limited to staff working in the province of Jeonnam. The results have important implications for the development of strategies to minimize turnover intention in long-term care. Reducing the intent to leave is desirable for issues of both cost reduction and quality of care. Managers could perhaps start to consider decreasing work overload assigned to staff. This study also provides some insight into the work status of new staff. Clearly this finding needs to be explored in further research studies. A more comprehensive model is likely required to adequately explain intention to leave the job.

The sustained economic growth cannot be expected without the balanced development in all the realms of industries. Korea has recorded the continuous high growth rate of economy, but it is now facing some difficulties in keeping the normal economic growth, because industrial workers do not like to work in some fields, the typical one of which is the fishery works. This thesis aims at studying the determinants of fishermen's job satisfaction(FJS) and the determinants of affecting the fishermen's trunover intention(FTI) to obtain and maintain the man power for fishing boats. This study assumes that the determinants which affact FJS are fishermen's work values, job characteristics, the attitude of accepting their fishery work, and that the determinants which affect FTI are FJS and their perceptions of labor market. This study concerns two kinds of Job satisfaction : one is an intrinsic satisfaction which comes directly from the work itself, and the other is an extrinsic satisfaction comes from the compensation for the work, but in this study “Pollnac's work satisfaction factor” is added as an additional determinant of FJS. There is a difference in job satisfactions between the individuals who have different work values. Some feel more satisfacttion than the others, which can be explained by the internal work values which assume the work is only a means for another objective of life. This study applies Hackman and 014ham's studies to the job characteristics that a worker's job satisfaction is positively related to the core job characteristis of the job. In addition, this study transformed their studies into variables. A job enrichment to reduce the simplicity of a work and make it more valueable can increase a job satisfaction, but an existing organization has limitation in redesigning the job for its enrichment. A reasonable answer about this matter can be obtained from the workers' subjective perceptins to highly regard the objective job characteristics. Worker's previews of fishery work also affect their job satisfaction because they are already informed of the details and charcteristics of the job that they have to carry out. A Job dissatisfaction causes their intention to leave jobs owing to general perceptions prevailing in labor markets.

A number of companies are considering for merger and acquisition (M&A) as one of business strategies for their growth and survival. However, many of them do not create the synergy they had sought, and failed M&A, often result in negative outcomes in terms of productivity, market share, profitability and turnover of qualified employees. There have been numerous research studies conducted to analyze the factors that determine the success and failure of M&A, and it has been found that with the increasing dependence of many companies on information systems, post-M&A IS (information systems) integration success has a critical effect on the success of M&A. However, there have been very few studies on post-M&A IS integration success, and most have been restricted to integration of IS organizations or physical information systems. In order to conduct a comprehensive research on the factors that affect the success of post-M&A IS integration, this study surveyed preceding researches on not only information systems but also strategic management, economics, finance, HRM (human resource management) and organization management. Based on the findings, a comprehensive and integrated model of the influential factors on post-M&A IS integration has been proposed. The proposed model categorizes the factors into perspectives of M&A, strategy, organization, HRM and IS, and provides an empirical evaluation of each factor on the success of IS integration based on comparative case studies.

Corporate governance is a system articulating the division of responsibilities among different company members, and defining the running rules and procedures for making decisions on corporate affairs. The separation of ownership and management in modern enterprises brings agency problems to the company shareholders, and it is wildly believed that good practice on corporate governance is essential to prevent managers from taking actions by which profiteering their own benefits but compromising the interests of shareholders. This research investigates the level of companies' compliance with the corporate governance codes to find whether significant differences in corporate governance practice exist between the listed construction companies and the national leading companies in Taiwan. Further exploration focuses on the correlation between the compliance level and the industrial features. The investigation finds that: (1)Construction companies display lower levels of corporate governance compliance; (2)Construction companies display lower levels of structural board independence and respect for stakeholders; (3)Compliance levels of construction companies are correlated with the number of employees and the ownership concentration; (4)Compliance levels of the whole sample companies are correlated with the factors representing firm size, such as turnover, capital and number of employees, but are independent of profitability as well as stock price volatility. The above empirical evidence characterizes the features of corporate governance in Taiwan listed construction companies, including: (1)Large companies lurking high risk of agency problems have more willingness to conduct corporate governance and meanwhile can afford higher costs for the conduction, so that their compliance level would be higher than smaller companies; (2)Construction companies in Taiwan have higher ownership concentration, on account of the industrial tradition of family business, and therefore pay less attention to the compliance with structural board independence and respect for stakeholders. However, the conclusions indicate that further studies are essential to clarify whether the above disparities would lead to a negative cycle of corporate governance practice in construction industry. The benefits of corporate governance should unfold more evidently to convince construction companies for improving their investment environment and stimulating their healthy growth.
