This study aims to identify DNA marker related to health index which is derived from fatty acid composition of Hanwoo meat. We investigated a genetic association between two SNPs (-867G>C and 878C>T) of SCD gene and health indexes. Two health index values (index of atherogenicity and index of thrombogenicity) were derived from a combination of fatty acid composition. Phenotypic correlation indicated that oleic acid (C18:1) was negatively correlated to index of atherogenicity (-0.84) and index of thrombogenicity (-0.91), respectively. Statistical analysis revealed that 878T>C SNP was significantly associated with IA (index of atherogenicity, p=0.012) and IT (index of thrombogenicity, p=0.006). There was no association between the regulatory SNPs (-867G>C and -877Gdel) and health indexes. Haplotype analysis detected 4 main haplotype (GdelT; 0.004, GdelC; 0.344, CGT; 0.350 and CGC; 0.261) in Hanwoo. The GdelT haplotype was significant on IA and IT. The effect of GdelT haplotype showed increasing IA and IT values, while GdelC haplotype has a decreasing IA and IT value in Hanwoo. In conclusion, the 878C>T SNP in the SCD gene seems to have an effect on this health index and might be implemented into animal breeding program.

고추, 인삼 또는 녹차는 흔히 접할 수 있는 특용작물로서 공통적으로 항균작용이 있는 것으로 알려지고 있다. 본 연구에서 는 고추, 인삼, 녹차를 배지에 영양원으로 첨가하여 느타리버섯의 원기 발생기간과 자실체 형성기간에 미치는 영향을 알아 보고자 하였다. 일반적으로 느타리버섯 배지의 조성은 톱밥 배지에 미강을 혼합하여 재배하고 있다. 배지는 참나무 톱밥과 미강을 일정한 조성으로 제작하고 고추, 인삼, 녹차를 5~20%로 첨가하였다. 그 결과 고추의 경우에는 원기 발생기간 및 자실체 형성기간이 단축되었으며, 인삼에서는 원기 발생기간과 자실체 형성기간에 유의적 차이가 없었다. 반면에 영양원 으로 녹차를 첨할수록 원기 발생기간이 지연되었고 자실체 형성기간은 억제되었다.

This research was performed to simulate shellfish production systems and sales in Gamak Bay, South Korea. To study the way the shellfish system generates maxima, a numerical model was developed to simulate the model under a control and a number of different scenarios. The program calculates the EMERGY flows by multiplying the flows of energy and materials by the appropriate solar transformity. In this study, an energy systems model was built to simulate the variation of sustainability for oyster aquaculture. The results of the simulation based on 2005 data that as oyster production yield slightly increases, money and assets increase to a steady state. When the program is run control simulation, the system reaches carrying capacity after 8 years. The simulation of models with price of purchased inputs increased with 3.5% inflation rate per year showed maximum benefit of shellfish production occurs after 6 years but amounts are less than control simulation, and then decreases slightly in money and yield results. The results with 3.5% inflation and increase of oyster price annually showed steady and slightly increase of money and yield.

The objective of this research is to apply more scientific, quantitative methods and procedures of environmental investigation to the development of the natural environment and the improvement of the human environment during the establishment of a sewage treatment plant and special facilities using environmental accounting. This research was performed to develop a method of strategic environmental assessment on the operation of sewage treatment plant and reuse of shellfish seeding areas through the use of environmental accounting based on EMERGY evaluation. The result was applied to marine environment policy in order to evaluate the real wealth of the regional environment and economy for both the present phase and the proposed developed phase. Using results from the comparison of EMERGY indices between the present situation and future scenarios, cost benefit analysis was performed for three different scenarios: (1) construction of a new sewage treatment plant, (2) relocation and recovery of the shellfish seeding area , and (3) relocation and re-seeding of shellfish area and construction of a new sewage treatment plant. Cost-benefit ratios of the three scenarios are 1.88, 0.94, and 1.38, respectively.

This research outlines a new method for evaluation of shellfish production in Gamak Bay based on the concept of EMERGY. Better understanding of those environmental factors influencing oyster production and the management of oyster stocks requires the ability to assess the real value of environmental sources such as solar energy, river, tide, wave, wind, and other physical mechanisms. In this research, EMERGY flows from environment sources were 76% for shellfish aquaculture in Gamak Bay. EMERGY yield ratio, Environmental Loading Ratio, and Sustainability Index were 4.26, 0.31 and 13.89, respectively. Using the Emergy evaluation data, the predicted maximum shellfish aquaculture production in Gamak Bay and the FDA (Food and Drug Administration, U.S.) designated area in Gamak Bay were 10,845 ton/y and 7,548 ton/yr, respectively. Since the predicted shellfish production was approximately 1.3 times more than produced shellfish production in 2005, the carrying capacity of Gamak Bay is estimated to be 1.3 times more than the present oyster production.

As forest land takes up 65% of the Korean peninsula, there have been continuing conflicts between the development and conservation of forest land. As the income level has changed over time, the usage of forest land in society has changed. There has been increasing demands for forest land for urban development and recreational use. On the other hand, a large proportion of the land is required to be preserved for the forest and the natural ecosystem in it. The existing management system for the forest land has been designed focusing on the management of the trees on the land, and not the land itself. Due to this limitation, the current management system of forest land has failed to protect the forest land from being developed indiscreetly, making it difficult to conserve and develop the forest land in an efficient way. A major question in forest land management is how to integrate economic use activities with the supporting ecosystems to maximize performance of the ecological-economic system. In order to promote sustainable use of forest resources, and to achieve efficient forest land management, it is prerequisite to evaluation on forest resources of natural ecosystems. Quantitative measures are needed that signify how necessary the services and products of forested ecosystems are to human endeavors. In this study, the natural wealth provided by forest land was quantified based on emergy synthesis. Emergy is a universal measure of real wealth of the work of nature and society made on a common basis. Thus, Calculations of emergy provide a basis for making choices about environment and economy following the general public policy to maximize real wealth. The goals of forest land management to achieve balance between the ecology and economy of its integrated system and to foster equity among the diverse outcomes of the forest land were assessed with emergy. Emergy was demonstrated to holistically integrated and quantify the interconnections of a coupled nature-human system allowing the goals of ecological balance and outcome equity to be measured quantitatively. Doing so will provide a better understanding of the basis of forest land wealth and the consequences of management decisions.

수치시뮬레이션 기법 중 하나인 SMAC법은 시간의 변화에 따른 유동의 현상을 해석하기 위해 MAC법을 수정 한 기법이다. 비압축 점성 흐름을 풀기 위해 Navier-Stokes 방정식을 사용하였으며, 유동을 가시화하기 위해 마커입자가 사용되었다. 본 연구에서는 SMAC법을 사용한 2차원 물기등 붕괴현상의 수치시뮬레이션을 수행하였으며, 시뮬레이션 결과는 Martin과 Moyce의 실험 결과 및 MPS법의 계산결과와 비교하였고, 좋은 결과가 얻어졌다. 또한
