With the increase of the aging population in Korea, the welfare of Korean elderly has become one of main concerns of the society. One essential factor that may enhance the quality of life of the elderly is the active social participation. Involvement in the volunteer activity is one form of social participation that benefits both society and individual. The purpose of this study is to examine the level of Korean elderly's participation in volunteer activities and factors related to their participation in the context of different age group. People aged 55 and over from wave 2 data of Korean Longitudinal Study of Ageing are grouped into pre-old(55-64), young old(65-75), and old old (75 and older). Main analytic tools include descriptive statistics and logistic regression analysis. Results indicated that social relationships of the elderly were the most important factors related with their participation with voluntary activities. Also highlighted is the importance of considering the diversity among the older population.

The present level of ubiquitous computing technology have developed to the point where Home-server provides services that user require directly for user in the intelligent space. But it will need intelligent system to provides more active services for user in the near future. In this paper, we define the environment information about situation that user is in as Context, and collect the Context that stereotype as 4W1H form for construct the system that can decision service will be provide from information about a situation that user is in, without user's involvement. Additionally we collect information about user's emotional state, use these informations as nodes of Bayesian network for probabilistic reasoning. From that, we materialize Context Awareness system about it that what kind of situation user is in. And, we propose the Context-based Service reasoning model using Bayesian Network from the result of Context Awareness.

The marketing system of non-timber forest products has been criticized as it mainly depends upon private local dealers, having too many steps between producers and consumers, we believe, which makes it less efficient. Meanwhile, there were only a few empirical studies of how they are delivered to consumers. In order to devise and implement targeted forest policies efficiently, it is quite necessary to understand the distribution channel of them. We analyzed the distribution channel of chestnut, bitter persimmon, oak mushroom, and wild greens by data analysis, field and phone survey, and then drew an implication for improving the marketing system. First of all, the number of middle step has to be reduced and the direct transaction has to be expended. In addition, we need to have more active involvement of Forest cooperative in production sites, adding values by processing, and the upgrade of current marketing centers of non-timber forest products, which have been launched since 2004 by Korea Forest Service.

The growing importance of product quality is becoming more and more daily apparent as we enter the age of globalization around the world. And the product safety is getting more focus as well as product quality. As a result, many domestic companies are putting a lot of emphasis on safety measures and management activities and these companies' products are mainly superior to other companies' product. When we separate the product quality procedure into 3 steps, i.e. quality secure-quality confirm-quality guarantee, of course the 1st step is the most important, but also 2nd step of product quality confirm process is important. And in mass production environment, sampling inspection is more desirable than the $100\;\%$ inspection procedure. As a part of globalization trend, KS system is also being revised and reestablished based on ISO, IEC, etc. which are based on international standard. Conventional KS sampling inspection standards were in many areas quite different from ISO sampling standards, only KS A 3102, 3104, 3151 are left and the rest become obsolete, and even the ones that are still around are planned to the gone step by step. It has been already 3 years since the new KS A ISO $2859-0\sim3$ sampling inspection process has been established which the abolition of the popular KS A 3101, KS A 3105, KS A 3109, yet the implementation rate is very slow. This study will attempt to analyze the new KS A ISO 2859-2 and KS A ISO 2859-3, and try to understand the difference as that the new standard can be easily understood and used widely among companies, by using examples. Our attempt is to help implement with the companies with active safety involvement but the final result can be spread among other companies as well in the near future.

Previously, we reported that water-extracted Acanthopanax senticasus exhibited anti-meta-static activity by stimulating the immune system. In this study, we fractionated glycoproteins (EN-SP) from the soluble protein layer (GF-AS) of A. senticasus and determined their basic chemical properties. We also investigated the anti-tumor and immunostimulating activities of the fractionated glycoprotein, EN-SP. We found that intravenous (i.v.) administration of GF-AS dramatically inhibited metastasis of colon26-M3.1 carcinoma cells to the lung in a dose-dependent manner. In vitro analysis showed GF-AS to enhance the proliferation of splenocytes. GF-AS also stimulated peritoneal macrophage, which was followed by the production of various cytokines such as IL-1$\beta$, TNF-$\alpha$, IL-12 and IFN-${\gamma}$. Furthermore, the production of these cytokines was partially blocked when peritoneal macrophage was cultured with the polyclonal antibodies against GF-AS. The depletion of NK cells by rabbit anti-asialo GM1 serum partly abolished the inhibitory effect of GF-AS on lung metastasis of colon26-M3.1 cells. Using gel filtration, EN-SP, an active glycoprotein fraction, is isolated from GF-AS. While both GF-AS and EN-SP stimulated the proliferatation of splenocytes of normal mice, EN-SP showed higher anti-metastatic activity and more potently stimulated the proliferation of splenocytes compared to GF-AS. These results suggest the use of EN-SP, the fractionated glycoprotein from A. senticasus, can be used as a therapeutical reagent to prevent or inhibit tumor metastasis.

Glucose 6-phosphate dehydrogenase (G6PDH, EC 1.1.1.49) in Deinococcus radiophilus, an extraordinarily UV-resistant bacterium, was investigated to gain insight into its resistance as it was shown to be involved in a scavenging system of superoxide $(O_2^{-1})$ and peroxide $(O_2^{-2})$ generated by UV and oxidative stresses. D. radiophilus possesses two G6PDH isoforms: G6PDH-1 and G6PDH-2, both showing dual coenzyme specificity for NAD and NADP. Both enzymes were detected throughout the growth phase; however, the substantial increase in G6PDH-1 observed at stationary phase or as the results of external oxidative stress indicates that this enzyme is inducible under stressful environmental conditions. The G6PDH-1 and G6PDH-2 were purified 122- and 44-fold (using NADP as cofactor), respectively. The purified G6PDH-1 and G6PDH-2 had the specific activity of 2,890 and 1,033 U/mg protein (using NADP as cofactor) and 3,078 and 1,076 U/mg protein (using NAD as cofactor), respectively. The isoforms also evidenced distinct structures; G6PDH-1 was a tetramer of 35 kDa subunits, whereas G6PDH-2 was a dimer of 60kDa subunits. The pIs of G6PDH-1 and G6PDH-2 were 6.4 and 5.7, respectively. Both G6PDH-1 and G6PDH-2 were inhibited by both ATP and oleic acid, but G6PDH-1 was found to be more susceptible to oleic acid than G6PDH-2. The profound inhibition of both enzymes by ${\beta}-naphthoquinone-4-sulfonic$ acid suggests the involvement of lysine at their active sites. $Cu^{2+}$ was a potent inhibitor to G6PDH-2, but a lesser degree to G6PDH-1. Both G6PDH-1 and G6PDH-2 showed an optimum activity at pH 8.0 and $30^{\circ}C$.

Many efforts have been made to improve the management of large-scale green spaces. How to manage large-scale green spaces and their active uses, as well as how to build relationships with local communities have been important issues. For this research, I reviewed the actual status of management, use and citizen participation at large-scale regional parks in Hyogo Prefecture. In addition, I studied the sustainable management through citizen participation of the Awaji Island Regional Park, where I have been involved for several years. I conducted various projects related to the use and management of the park, and examined the direction of citizen participation by conducting questionnaires and interviews. (1) Through interviews about the park, I collected opinions, including good points, problems, and potential solutions through physical and programming measures. (2) I examined what kinds of activities should be conducted in the park in order to revitalize park use and stimulate the surrounding communities. (3) I examined the current status of citizen participation while citizens carried out activities of their own planning. (4) I studied what is necessary to sustain park events and other activities. As a result, I came to the following conclusions. (1) Provision of information that is easy to access, including signs in the park, explanation of routes in large parks, and other techniques that help people become familiar with park facilities, is very important. (2) Local community events, and programs that draw out the willingness and capabilities of volunteers are effective. (3) Several different types of participation exist, including volunteers, guests, staff who work continuously for the project, coordinators, and professional specialists. (4) To sustain citizen involvement in the use and management of large-scale parks, a system that includes coordinators should be developed.

The purpose of this article is to analyze the tendency and characteristics in armed conflict in post-Cold War era on the basis of Uppsala conflict data program(UCDP) datasets. The collapse of bipolarity and the end of cold War proved a watershed in the dynamics of international conflict. The major shift in the nature of conflict has been away from interstate conflict, leaving intrastate conflict. Major powers have acted carefully against each other and been willing to understand the interests of other to avoid military confrontation and crash. As the means of termination for armed conflict, there is a stronger emphasis on the peace settlement like peace agreement and ceasefire agreement than military victory. Many intrastate conflicts become internationalized, through the involvement of diaspora communities, or regionalized through a spillover effect into neighboring countries. Since the end of the Cold War, the UN has taken a much more active role in conflict management and conflict resolution.
