One of them is online community which is popular among this modern society. However, it is not appropriate to suggest that online community is solely for personal usage or solely for work-related usage. The usage of online community goes beyond only one purpose. On the other hand, our daily activities whether personal or work-related activities are usually accompanied with preconception ideas whether it is a fun activity or not. However, even with this preconception, individuals are still enjoying themselves while doing activities that are considered as boring or mundane. Furthermore, individuals are really into the activities that they forgot about their surrounding and found themselves being in flow while conducting these activities. Unfortunately, there is little research done in South Korea addressing this emotion related factors. Because of that, more research concerning emotion related factors need to be conducted to better understand users behavior especially in online environment. With regards to that concern, this research studied two distinct everyday activities which are studying and playing games in online community. It is expected that when an individual feels more enjoyable and feels more comfortable, it will be more likely for them to be more satisfied. This satisfaction will lead them to being in a flow state. Hence, this study proposed three hypotheses. In order to investigate these three hypotheses, studies were conducted in two stages. The first stage was conducted in order to derive the implicit knowledge about fun from the participants. The second stage was done by an empirical study. It was conducted with two sample groups. The first group is the study group and the second group is the play games group. There were asked a set of questionnaires related to their enjoyment, comfort, satisfaction and flow while conducting the relevant activity. The results showed that both groups reached the state of flow regardless whether they belong to the study group or play games group. Therefore, the preconception idea about an activity does not promote or prevent individuals from feeling enjoyment, feeling comfortable and achieve satisfaction while conducting those activities.

This study was performed to investigate the effect of soy isoflavone on plasma nitrite concentration and the antioxidant enzyme activities of erythrocyte and the liver using adult male rats fed high fat diet. Seven-week old male Sprague Dawley rats were divided into three groups and fed high fat diet (15% beef tallow, 1 % cholesterol; control: IF0) or high fat diets containing isoflavone 80 ppm (IF80) or 320 ppm (IF320) for 10 weeks. Plasma nitrite concentration as a vasodilator, and antioxidant enzyme activities in erythrocytes and the liver were measured. Plasma nitrite concentration was increased by 45% and 35%, respectively, in IF80 and IF320 than in IF0 group. Erythrocyte catalase, glutathione peroxidase (GPx) and glutathione reductase (GR) activities increased by 31 %, 30% and 40% in IF320 compared to IF0 group. Especially, erythrocyte GR activity increased by 61 % in IF80 group. However, catalase activity in the liver was decreased in IF80 group. GPx and GR activities in the liver were not differ among groups. The results suggest that soy isoflavone have the protective effect against risk factors related with cardiovascular disease by improving vasodilator factor, nitrite, and antioxidant enzyme activities in blood.

We have conducted a comprehensive literature review regarding the chemical constituents and biological activities of Korean black ginseng(Panax ginseng C. A. Meyer), three to nine times-steamed and dried ginseng, which shows strong black color through Maillared browning reaction. It has been reported that some chemically deglycosylated and transformed saponins are obtained from black ginseng as artifacts produced during intensive steaming. They have been known to be ginsenosides Rg3, Rg4, Rg5, Rg6, Rh1, Rh2, Rh4, Rk1 and Rk3, quite different from those of red ginseng, among which ginsenosides Rg3, Rg5 and Rk1 are considered to be major components. And also, black ginseng has been recently found to demonstrate anticancer, recovery from learning and memory damages, hypontensive, antidiabetic, antiobesitic, tonic and antiatopic activities, together with antioxidative and exercise performance improving activities, exhibiting their effects to be a little bit stronger than those of red ginseng. These findings suggest that black ginsng might play an important role in the development of promising functional foods and drugs from the viewpoint of the chemical composition and biological activities of black ginseng with a distinction from those of white and red ginsengs. In this review, the authors will survey and evaluate further functions of black ginseng with a focus on its physicochemical properties and biological activities.

This study was designed to analyse the performance and the mechanisms of workers' participation and communications in industrial accident prevention activities leading to the reduction of industrial accidents. This study also aimed to find out the causal relationship influencing the promotion of prevention activities of industrial accidents. Of the manufacturing businesses with more than 5 workers as the population of the survey, a questionnaire was conducted with 2,500 workspaces chosen by stratified sampling. Out of 2500 workspaces, 971 workspaces equipped with industrial safety and health committee were analysed in this study. According to the results of this study, the primary influential factors on safety activities were the management of industrial accidents and the cooperations between supervisors and workers on site. The secondary influential factor was the establishment of industrial safety and health committee. Regarding the effectiveness of industrial accident reduction, -0.01 was shown by workplace safety activities by themselves and -0.09 was shown by participation and communications through indirect safety activities. This indicated workers' participation and communications play an important role in the reduction of industrial accidents. By discovering the clue to the mechanism of the workers' participation and communications, this study is expected to stimulate the reduction of industrial accidents by emphasizing the importance of workers' participation and communications in resolving the safety and health problem in the workplaces.
