This thesis aims to examine the formation, and the religious meaning and symbolism of Beob-Lak, which is attached to the preacher's clothing as a full dress of Won-Buddhism, which, as a new religion, was originated in Korea's historical foundation in 1916. In addition, it tries to provide the basic data for the study on Korean religious costume by examining Beob-Lak in the context of social atmosphere of Korea, which has accepted various religions. As a result, I found that Beob-Lak was originated from the different colored lines of the early Japanese Buddhist religious costume and it employed rochza as an independent component, but that the present protocol of Beob-Lak was completed by the first Jongbeobsa Jeongsan Jongsa in the late 1950s and all the religious workers have put it on with the religious costume in great worships since the early 1980s. Beob-Lak of Won-Buddhism, which employs Ilwonsang Beobsinbul as the symbol of its religious doctrine, symbolizes the succession of Beob and represents the will to repay the teacher's favors to hand down the great truth. At the center, Ilwonsan(one round shape) is the symbol of the innate place for everything in the universe, and its yellow color symbolizes the highest nobleness. I expect to see following researches which deal with the costume of Won-Buddhism from various views on the basis of this study on the formation and development of Beob-Lak, which is the symbol of formal full dress of Won-Buddhism as Korea-style new religion created over 90 years ago.

As a part of our ongoing effort to develop new antineoplastic immunostimulator from natural sources, bioassay-directed fractionationn of polysaccharides from Korean red ginseng was carried out by observing the proliferation of marine spleen cells and the generation of lymphoklne activated killer (LAK) cells. The acidic polysaccharide fractions proliferated spleen cells and generated LAK cells in proportion to their acidity in vitro. The LAK cell which was induced by ginseng showed tumoricidal activity against both NK celt sensitive and insensitive tumor target cells without major histocompatibility (MHC) restriction. Adherent macrophages and CD4+helper T cells were involved in the generation of the LAK cells. The acidic polysaccharide from Korean red ginseng synerglzed with recombinant IL-2 (rIff-2) at lower than 3 U/ml. The optimal doses of the acidic polysaccharide from Korean red ginseng for the proliferation of spleen cells and for the generation of LAK cells were 1 mg/ml and 100 $\mu\textrm{g}$/ml, respectively; this means that the mechanisms for the both activities may be different from each other.

One of the goals of tumor immunotherapy is to generate immune cells with potent anti-tumor activity through in vitro techniques using peripheral blood collected from patients. However, cancer patients generally have poor immunological function. Thus using patient T cells, which have reduced in vitro proliferative capabilities and less tumor cell killing activity to generate lymphokine-activated killer (LAK) cells, fails to achieve optimal clinical efficacy. Interleukin-2 (IL-2) is a potent activating cytokine for both T cells and natural killer cells. Thus, this study aimed to identify optimal donors for allogeneic LAK cell immunotherapy based on single nucleotide polymorphisms (SNP) in the IL-2 and IL-2R genes. IL-2 and IL-2R SNPs were analyzed using HRM-PCR. LAK cells were derived from peripheral blood mononuclear cells by culturing with IL-2. The frequency and tumor-killing activity of LAK cells in each group were analyzed by flow cytometry and tumor cell killing assays, respectively. Regarding polymorphisms at IL-2-330 (rs2069762) T/G, LAK cells from GG donors had significantly greater proliferation, tumor-killing activity, and IFN-${\gamma}$ production than LAK cells from TT donors (P<0.05). Regarding polymorphisms at IL-2R rs2104286 A/G, LAK cell proliferation and tumor cell killing were significantly greater in LAK cells from AA donors than GG donors (P<0.05). These data suggest that either IL-2-330(rs2069762)T/G GG donors or IL-2R rs2104286 A/G AA donors are excellent candidates for allogeneic LAK cell immunotherapy.

Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production, making up 32.4% of the total coffee area in Vietnam. At present, coffee is the main income source for the province, with coffee accounting for 85% and 40%(2010) of the export value of the province and of the country, respectively. Although the rapid development of Dak Lak's coffee production significantly benefits the province and its coffee planters socioeconomically, emerging urgent problems such as land dispute among ethic groups need to be addressed. This paper aims to examine how coffee-production development in Dak Lak has affected land mobility. In addition, we consider how these changes have affected the livelihoods of the Kinh-the majority ethnic group in Vietnam-as well as the ethnic minorities. As a result, it is pointed out that the coffee development in Dak Lak creates the individual ownership on land. This ownership is more and more fortified when the encroaching land of the Kinh immigrants happens impetuously defying the customary law of the ethnic minorities.

This study explores spatial and temporal evloution of Dak Lak as one of coffee frontiers in Vietnam. So far, many authiors have studied this region under the framework of global-local interactions and emphasized the impacts from global coffee market. However not only unique past situation as the underdeveloped frontier and also the interventions of Vietamese government for transforming her socioeconomic system have played not less pivotal role than the global market in forging the present geography of Dak Lak. Under this logic, this study have traced restucturing in production system of state farms and smallholders' particpation in coffee farming. This study shows that various and unique localities as a frontier and specific situation accrued from transitional process has reflected in the present geography of coffee production in Dak Lak. Finally, this paper can be arguable to contribute some useful insights for understanding the evolution of coffee frontier in Vietnam.

Background: Nitric oxide (NO), a cytotoxic molecule is produced in various tissues including tumor cells during interleukin-2 (IL-2) therapy . Lymphokine-activated killer (LAK) cells are induced during IL-2 therapy, and have cytotoxic activity against tumor cells. The current study investigated the effects of NO synthesized in target cells or exposure of target cells to NO on the sensitivity of target cells to LAK cell cytotoxicity. Methods: Cytotoxicity was measured using 4 h chromium release assays. LAK cells which were induced by a 4 day incubation of BALB/c mouse splenocytes with IL-2 (6,000 IU/mL) were employed as effector cells. RD-995 skin tumor cells originated from a C3H/HeN mouse were employed as target cells. NO synthesis in target cells was induced by a 24 h incubation of RD-995 cells with $IFN{\gamma}$ (25 U/mL), TNF (50 U/mL) and IL-1 (20 U/mL). S-nitrosyl acetylpenicillamine (SNAP), an NO donor, was used to expose target cells to NO. $N^G$-monomethyl-L-arginine (MLA) and carboxy-PTIO were added during cytotoxicity assays to inhibit NO synthesis, and to scavenge NO produced by target cells, respectively. Results: Sensitivity of NO-producing RD-995 cells to LAK cell cytotoxicity was decreased by addition of MLA and carboxy-PTIO during cytotoxicity assays. However, the two reagents had no effect on the sensitivity of non-NO-producing RD-995 cells. Pretreatment of RD-995 target cells with SNAP increased the sensitivity in comparison with untreated cells. Conclusions: Sensitivity of target cells to LAK cell cytotoxicity is increased by target cell NO synthesis or exposure to NO. Further studies are needed to evaluate whether these in vitro results have relevance to in vivo phenomena.

This paper aims to clarify the process of institutionalization of customary land ownership along with the expansion of coffee plantation in Dak Lak Province, Vietnam. Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production. The expansion of coffee plantation in Dak Lak have brought a severe competition of land resources, and resulted in the transition of land ownership scheme from customary commons by ethnic minorities to those of exculsive private assets which is secured by the state. Institutionalization of customary land ownership in Dak Lak, however, was differently happened according to the geography from the center of state power as well as the value of land resources. In this paper, the authors argue that institutionalization of customary land ownership in Dak Lak was a result of compromising between statemaking process in the frontiers and "everyday resistance" of ethnic minorities, comparing 3 geographically different ethnic minorities' communities.

The objective of this research is to provide an understanding of how coffee production has been taking place since the coffee industry in Vietnam came out in the global market after Doi Moi. Current research tries to understand how the local households of coffee production adjusts to their production process according to internal and external influences. In order to explore coffee production in the level of local and household units, the structure of coffee production in Dak Lak is first explored in terms of production and sales with the cases from two communes. The examination reveals that general characteristics of coffee crops that would reflect coffee production structure. Further, this study interrogates farmers' response to reflect some direct and indirect influences in recent years. That shows how the elements of coffee production in global market induce a change of coffee production in the study area. Those aspects are analyzed in relation to yearly coffee price fluctuation and diversification. Also, this research explores some of farmers' responses toward the environmental friendly coffee production.

Vietnam's growth as the second largest coffee producer in the world has been fueled by domestic migration into central highlands. However, the detail migration processes have not been explicitly discussed. In particular, the existing literatures tend to describe the migration flow in a framework of planned migration versus spontaneous migration, paying less attention to the linkage between them. With a case study of Dak Lak province which is the leading robusta producer in Vietnam, this research investigates the linkage between planned and spontaneous migration in a multiscalar approach. The statistic data allow the researcher to know temporal association between the two type of migration in a provine scale. The survey and interview about two coffee-producing communes - Ea H'Ding in Cu M'gar district and Doan Ket in Krung Buk district - inform us that the linkage between planned and spontaneous migration is contingent to the local contexts including ethnic composition, timing of settlements, governement's development program, and timing of a large flow of in-migration.
