The random access systems, with retransmission diversity (RD) employment, over large random spreading code division multiple access (CDMA) channel subject to fading is investigated, under the assumption of infinite number of users and infinite spreading gain with their ratio converging to a constant. The low bound of the signal to interference and noise ratio (SINR) is shown to converge almost surely to a constant. The throughput, spectrum efficiency and energy efficiency in the dominating systems are obtained. The analytical results are confirmed by simulations. We find that in high traffic loads the throughput with fading is higher than that without. When the energy efficiency increases, the spectrum efficiency tends to two contrary values due to SNR increases or decreases. For the ordinary stable systems, the stability region is shown to shrink as the traffic increases and enlarge with RD employment.

The world's major countries have focused on the renewable energy industry as the solution to climate change and the energy crisis. Nevertheless, there are no studies on the economic effects of the renewable energy industry. This study analyzed the economic effects of Korea's renewable energy industry by using the 2010 Input-Output Table. It is estimated that Korea's renewable energy industry made a production-induced effect of 2.0262 won, and a value-added-induced effect of 0.6138 won through an increase in output growth of 1 won, and an employment-induced effect of 2.3046 labors through an increase in output growth of 1 billion won. Both the effect ratio and the response ratio were greater than 1, which means the renewable energy industry is an intermediate manufacturing industry whose forward linkage effect and backward linkage effects are large. These results show differences with previous studies that classified electricity sector and renewable energy industry into final primary production industries. It is expected that the economic effects of the renewable energy industry will become greater in the future. Therefore, research on statistics related to the renewable energy industry is needed for more precise analysis.

Background: There has been considerable interest in Japanese society in the problem of work-related stress leading to depressive symptoms, and an increasing number of primary houseworkers maintain paid employment. The purpose of this study was to examine the differential impact of multiple roles associated with psychological distress among Japanese workers. Methods: We studied 722 men and women aged 18-83 years in a cross-sectional study. The K10 questionnaire was used to examine psychological distress. Results: The proportion of participants with psychological distress was higher in women (17.8%) compared with men (11.5%). Having three roles significantly decreased the risk of psychological distress [women: odds ratio (OR), 0.37-fold; men: OR, 0.41] compared with only one role. In working married women, there was significantly less psychological distress (OR, 0.27), and those with childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.38) than those with only an employment role. Similarly, working married men who had childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.41) than those who had only an employment role. Conclusion: The present study demonstrated that participants who had only an employment role had an increased risk of psychological distress. The degree of psychological distress was not determined solely by the number of roles. It is important to have balance between work and family life to reduce role conflict and/or role submersion, which in turn may reduce the risk of psychological distress.

There is a growing interest on entrepreneurship for undergraduate students to enhance their employment ratio because they have big difficulty in getting a job in Korea as well as Vietnam. Currently, on-line business is booming because customers feel convenience in approaching on-line store. Therefore, this study has explored identifying the factors to affect entrepreneurial intention of being e-commerce trader for the undergraduates in Korean universities as well as Vietnam universities. In addition to this, the study has also investigated the difference of the results between Korea and Vietnam. The results of the study are as follows ; First, entrepreneurial knowledge affects positively on entrepreneurial intention for being e-commerce trader. Second, employment barrier also affects positively on entrepreneurial intention for being e-commerce trader. Third, social perception on entrepreneurship mediates the relationship between employment barrier and entrepreneurial intention for being e-commerce trader. Lastly, the level of entrepreneurial intention for vietnam undergraduate students shows higher than that of Korean undergraduate students. Since there was lack of recognition as to the importance for entrepreneurial intention of being e-commerce trader in Korea, Korean government can refer to the results of this survey and implement the related policies to enhance related entrepreneurial intention. This indicates that when it comes to the establishment of new ventures in Korea, entrepreneurial education has been the focus of interest such as making business plan, setting up strategy, marketing the products etc. In this regard, this research is expected to be used for the development for the future policies to boost youth entrepreneurship in Korea.
