생물다양성협약에서 국가 생물유전자원의 주권을 인정함에 따라 국가별로 생물유전자원의 관리에 대한 법적인 체계를 갖추어야 할 시기가 도래하였다. 생물유전자원의 관리에 있어서 가장 중요한 단계가 접근과 생물자원에서 파생하는 이익공유이다. 제6차 생물다양성협약 당사국 회의에서 채택된 본 지침은 접근과 이익공유과정에서 필수적인 상호합의조건과 사전통보승인제도를 포함하고 있다. 상호합의조건은 원산국과 이용 실체간의 계약 협정이고 사전통보승인제도는 생물자원 접근 전에 승인하는 것과 관련된 생물유전자원 관련 특이 제도이다. 아울러 국가연락기관과 국가책임기관의 책임, 유인조치 등에 관한 내용을 포함하고 있다. 우리나라의 생물유전자원 접근 관련 법률을 분석해 볼 때, 생물유전자원에 대한 이익공유와 특허권 문제가 고려되어 있지 않다. 생물유전자원 접근규제와 체계적인 관리를 위해서 정보 유용화 및 공개, 지적재산권을 조절하는 기관과 기타 이해관계자의 조정을 위한 국가관할기관의 역할이 중요하다. 다만, 이런 국가적 접근규제가 생물다양성관련 연구를 저해하지 않아야 하고 생물다양성협약의 목적인 생물다양성의 보존과 지속 가능한 이용에 위배되어서는 안 될 것이다.

Biological assessments are the primary tool for evaluating the biological condition of a water body and makes it possible to understand accumulative and long-term effect of stressors. They also provide reliable biological information for which disturbed systems are to be restored. Sustainable water environment is not enough with attaining only the clean water, but it should sustain healthy and diverse aquatic life. Aquatic organisms are affected by various factors, including not only water quality but also habitat condition and stressors, and thus good condition of both physical and chemical water quality is prerequisite for sustaining healthy organisms. Therefore, biological assessment, along with other physical and chemical assessments, are crucial for evaluating the health of a water body. Overall, sustainability of water environment demands the attainment and maintenance of ecological integrity, which is resulted from the combination of physical, chemical and biological integrity. The biological criteria will play very important role in the water resource management and policy issues, and thus bioassessment program should be fully implemented and supported eventually by the law. To keep ecosystem health of water environment safely from the toxic pollutants and other stressors, the following suggestions need to be considered in environmental quality standards in Korea. For the first step, the biological indicators need to be introduced in evaluating river quality condition; they provide a qualitative description of biological condition of water body. Secondly, the biological water quality standards using biotic indices should be developed and implemented under the consideration of characteristics of Korean river systems. Lastly, the ecological status classification regime (ESCR) should be developed and introduced; it could be used in quality assessment of the water environment in general. In developing ESCR, integration of physico-chemical, biological, and habitat parameters should be taken into account.

This study was performed to estimate environmental and biological monitoring of workers exposed to methyl bromide through quarantine fumigation. Airborne methyl bromide and it's metabolites were analyzed by gas chromatography and ion chromatography, respectively. The results are as followings; airborne concentration of methyl bromide(TWA) was $2.08{\pm}1.56ppm$(N=8). Dispersion and setting/degas groups were $0.67{\pm}0.12ppm$(N=2) and $2.54{\pm}1.53ppm$(N=6), respectively. Bromide ion concentration in serum was $23.40{\pm}14.91mg/{\ell}$(N=10) in the exposed workers and $4.74{\pm}0.82mg/{\ell}$(N=21) in the non-exposed workers. Bromide ion concentration in urine was $35.56{\pm}26.89mg/{\ell}$(N=11) in exposed group and $6.62{\pm}2.31mg/{\ell}$(N=21) in non-exposed group. Good correlation was observed between concentration of serum and urine ($r^2$=0.890 p<0.01). No significant correlations of other determinants were observed. Calculated from a regressive curve, the biological half lifes of serum and urine were 10.7 and 5.9 days. In these results, biological monitoring of bromide ion of serum and urine provided useful information for evaluating exposure of workers to methyl bromide, so that an availability of bromide ion of biological samples was showed as biological monitoring indices for methyl bromide.

The LIM domain-containing proteins are dominantly found in plants and play a significant role in various biological processes such as gene transcription as well as actin cytoskeletal organization. Nevertheless, genome-wide identification as well as functional analysis of the LIM gene family have not yet been reported in the economically important plant sorghum (Sorghum bicolor L.). Therefore, we conducted an in silico identification and characterization of LIM genes in S. bicolor genome using integrated bioinformatics approaches. Based on phylogenetic tree analysis and conserved domain, we identified five LIM genes in S. bicolor (SbLIM) genome corresponding to Arabidopsis LIM (AtLIM) genes. The conserved domain, motif as well as gene structure analyses of the SbLIM gene family showed the similarity within the SbLIM and AtLIM members. The gene ontology (GO) enrichment study revealed that the candidate LIM genes are directly involved in cytoskeletal organization and various other important biological as well as molecular pathways. Some important families of regulating transcription factors such as ERF, MYB, WRKY, NAC, bZIP, C2H2, Dof, and G2-like were detected by analyzing their interaction network with identified SbLIM genes. The cis-acting regulatory elements related to predicted SbLIM genes were identified as responsive to light, hormones, stress, and other functions. The present study will provide valuable useful information about LIM genes in sorghum which would pave the way for the future study of functional pathways of candidate SbLIM genes as well as their regulatory factors in wet-lab experiments.

The northeastern Pacific and eastern Bering Sea supports large and divers finfish and shellfish compelxes. The North Pacific fishing grounds are largest fish production total 30.89 percent of the world in 1983. Recent action by the around countries extending their fisheies jurisdiction to 200 mile has provided a new environment. The new approch to fisheries management has resulted in an arormous expansion in tile demand for scientific information. These are no longer limited to biological concerns. Emphasis has been focused recently on the need to understand the economic, social, politics and philosophy characteristics of a fishing and how they will be affected by management decisions. The horizontal management and portfolio management for fisheries has increased interest in complex biological models and the coupling of these models with economic, politics and phyisophy components. Successful completion of this task will require and expanded understanding of oceanographic, biological, economic, social, politics and philosophic process associated with fisheries. Particular attention should be devoted to acquiring information an data processing for Korean trawl fishery, stock assessment in the areas. The need for international collaboration in management must be stressed. Some northeast Pacific and eastern Bering Sea fish stock migrate over long distances and political boundaries. Further, nearly all the fish stocks are harvested by several nations. The features require cooperation and coordination of research activities. The horizontal management will be made a way these activities for the around countries in the sea. Strongly, tile proposed again, Pacific International Council for Exploration of the Seas, PICES will interest between all users of the area's fisheries.

본 연구에서는 생물학적 모방에 따른 물고기 로봇의 직진유영에 관한 연구로써, Liu 등이 제안한 꼬리 모션 함수를 푸우리에 급수 전개의 7차 항까지 고려한 제안된 방법과 일반적인 사인함수만으로 근사한 방법과 비교하여 모의실험 하였다. 일반적으로 로봇 물고기의 꼬리 링크의 길이가 길어지고 링크가 많을 경우, 로봇 물고기의 꼬리 모션 함수의 말단 회전 관절 궤적은 사인 함수의 모양과 매우 다르다. 그러므로 로봇 물고기의 꼬리 궤적을 단순한 푸우리에 급수 전개의 기본파 성분만으로 근사하기에는 문제가 있다. 제안된 방법과 일반적인 사인함수만으로 근사한 방법의 모의실험 결과 제안된 방법이 로봇 물고기의 추력과 속도에서 10%정도 뛰어남을 보였다.
