We describe and illustrate five species of shrimp of the genus Solenocera, collected from the Korean exclusive economic zone (EEZ) between 2001 and 2003 and a commercial seafood market in Busan, South Korea, in 2005. Four of these species, S. alticarinata Kubo 1949, S. comata Stebbing 1915, S. koelbeli De Man 1911, and S. pectinulata Kubo 1949, are new records for the Koreas. The fifth, S. melantho De Man 1907, is a ubiquitous and commercially important species in the region. This report extends the known range of S. pectinulata to Jeju Island in the East China Sea. A key to these species is presented.

The price and revenue of rice are expected to decrease due to increasing rice imports, decreasing consumption and the discontinuance of the government's rice procurement. This degenerating profitability is leading to a rise in the cultivation of upland-crops such as beans, fodder crops and fruits in paddy fields. However, there is a lack of research on the selection of rice substitute crops which are adaptable to the relevant region through profitability analysis. This research, therefore, analyzed investment profitability of rice substitute crops for Cheorwon-gun area in Kangwon province. The study applied net present value (NPV) and internal rate of return (IRR), which fit for mutually exclusive investments that make one selection to the exclusion of other crops. Target crops are green house plants in Cheorwon-gun area. Financial analysis showed paprika and cucumber have investment feasibility for automated vinyl greenhouses and conventional plastic greenhouses respectively.

이 연구는 광양만권에 위치한 여수시·순천시·광양시 등 3개 도시 간 도시체계 및 공간구조 변화를 고찰한 것이다. 중앙정부가 광양만권에서 수행한 대규모 개발사업, 1960년대 중반 제2정유공장 건설, 1980년대 중반 POSCO 광양제철소 준공, 1987년 시작된 광양항컨테이부두 착공과 2003년 광양만권경제자유구역 지정, 2012년 여수세계박람회 개최 등에 힘입어 3개 도시의 산업화와 도시화가 진행되어 광양만권은 우리나라 대표적인 임해형 산업벨트를 형성한다. 그러나 역사적으로 순천은 광양만권을 포함한 전남 동부지역에서 독점적인 중심지 기능을 수행하였다. 중앙정부가 추진한 전술한 개발사업은 광양만권에 위치한 3개 도시 간 도시체계와 공간구조를 순천 중심의 단핵형에서 네트워크형으로 변화를 만들어낸다. 그리고 2012여수세계박람회 개최 이후 3개 도시 간 연결성과 통합성이 강화되면서 광양만권 공간구조는 네트워크형 공간구조로 재편되고 있고, 이런 추세는 향후 더욱 강화될 것으로 전망된다.

The Yellow Sea and the East China Sea are the most important fishing grounds for the fishing industry of Korea, China and Japan which are major coastal states of these Seas. But the fishery resources in these fishing grounds are almost exhausted and also the sea region is seriously polluted. Accordingly an international joint countermeasure is necessary to recover the fishery resources and to keep the fishery a continuous industry. The authors inspected the existing fishery policies and international fishery relationship of the three coastal states, and suggested rational conservation and management regime of the fishery resources in these sea regions. 1. At present the legal status of the sea region beyond territorial sea is the high sea, for that reason the international cooperation is urgently needed to establish common regime for conservation and management of the fishery resources. 2. A series of scientific research on ecological system of fishery resources must be carried out in the sea region first of all for that purpose. 3. The existing Korea-Japanese Fishery Agreement and Sino-Japanese Fishery Agreement should be reformed to coincide with the new legal order of the UNLOS Convention, and the Sino-Korean Fishery Agreement should be concluded newly on the identical line. 4. As a conclusion, a joint conservation and management regime through a regional fishery organization or a individual conservation and management regime through the promulgation of exclusive economic zone by each state can be suggested to resolve the fishery resources conservation problem in the Yellow Sea and the East China Sea.

This study has studied the phenomenon exclusive to the activity of skin scuba among marine sports in Busan region, and such empirical studies are for the development of skin scuba, and even of the entire marine sports, and in order to achieve such objective, the study method centered around qualitative study method of in-depth interview, participatory observation, and documentation study, the results of which are as follows. First is the advantage of the local environment as an open-water location. This study area has beaches of pebbles, and the underwater is also comprised of pebbles up to a certain distance, securing a superior underwater visibility compared to the sand of other Busan regions, and such local environment is thought to be an advantage of skin scuba activity. Second is the satisfaction of accessibility. This study area had an advantage in participant accessibility, which is thought to act as a good strength for the marine sports development of this area in the future. Third is the satisfaction of education. The club instructors of this study area had various marine sports-related licenses such as skin scuba, along with marine lifeguard trainer qualifications to prepare against safety accidents, which are also thought to have positive influences on the education satisfaction for beginners. Fourth is the inconvenient subsidiary facility. This study area has great natural environment for open waters, but the subsidiary facilities of the club for skin scuba activity was found to be very inconvenient by this study, and for the future development of skin scuba, the improvement of subsidiary facilities should be considered. Fifth is the inconvenient parking facilities. The participants in this study area agreed upon the inconvenience of the parking issue alongside the subsidiary facilities. There are always parking issues near the coasts of Busan region, and in order to resolve such issues, active assistance from the City of Busan and each local government, and if such methods are well proposed, the conflict between the marine sports participants and local residents shall be resolved, it would play a great role in the development of marine sports.

산악관광은 독특한 자연환경과 문화를 기반으로 모험추구레저와 다양한 문화를 체험할 수 있는 대안관광으로의 가치와 의미를 부여할 수 있는 특성을 갖고 있다. 특히 산악관광의 대표적 목적지인 히말라야산맥의 관광대상지에서는 지역개발의 최고 목표이자 최적의 수단으로 인식되고 있으며 많은 관심과 개발이 진행되고 있다. 하지만 물리적인 접근성이 미약하고 문화적인 수용력이 매우 낮은 산악지역의 관광 및 레저개발은 단기적으로 지역경제활성화 및 지역 인프라 확대에는 많은 기여를 하고 있지만 실질적인 지역소득연계나 사회, 문화, 환경적으로 부정적인 영향도 간과할 수 없는 상황이다. 본 연구는 히말라야산맥의 대표적인 산악관광지로 발돋움하고 있는 네팔과 북부 인도지역을 중심으로 산악관광을 통한 지역개발 현황과 문제점을 제시하고 이에 대한 대안을 모색하는데 있다. 문명의 개발로부터 소외되었던 히말라야산맥 지역의 관광개발은 지역소득과 고용효과에 대단한 성장추세가 지속되고 있고 관광산업에 대한 신뢰와 희망 또한 매우 높은 편이다. 하지만 단기간의 개발에 따른 관광개발의 부정적인 현상들이 현실적으로 나타남에 따라 보전과 보호 및 개발의 관계성에 대한 인식이 높아지고 있으며, 지속 가능한 개발의 필요성을 각인하게 되었다. 결국 생태계 및 문화유산 보호와 지역개발의 두 가지 목적을 성취하는 개발방안의 논의와 구체적이고 실천적인 방향성의 제시가 요구된다. 특히 NGO를 중심으로 복합적인 산악관광협의체를 설립과 액션플랜이 관건이다.

Objectives : The application of polymerase chain reaction (PCR) for the discrimination of the herbal medicine Leonuri Herba (Leonurus japonicus) was evaluated by the comparison of the DNA sequence with Lamiaceae herbal medicine. Method : Genetic analysis showed that phylogenetic tree and comparing sequences through the DNA analysis of rbcL (ribulose-1, 5-bisphosphatecarboxylase) region and trnL-F (tRNA-Leu, trnL-trnF intergeni cspacer, and tRNA-Phe) region of chloroplast DNA from six Lamiaceae sold in market. And we developed IMCF and IMCR primers in order to distinction Leonuri Herba in six Lamiaceae using rbcL and trnL-F sequences. Results : Genetic analysis showed that six Lamiaceae showed individual group on phylogenetic tree. PCR amplification product of Leonuri Herba and another five Lamiaceae were developed for amplification of a 281 bp sequence and the specific PCR amplification of a 460 bp sequence that was exclusive to Leonuri Herba was designed using IMCF and IMCR primers. Conclusion : PCR analysis based on the chloroplast DNA sequences allows the discrimination of Leonuri Herba-based medicine.

This paper proposes a novel Random Scheduling Algorithm based on Subregion Coverage (RSASC), to solve the SET K-cover problem (an NP-complete problem). SET K-cover problem distributes the set of sensors into the maximum number of mutually exclusive subsets (MESSs) in such a way that each of them can be scheduled for lifetime extension of WSN. Sensor coverage divides the target region into different subregions. RSASC first sorts the subregions in the ascending order concerning their sensor coverage. Then, it forms the subregion groups according to their similar sensor coverage. Lastly, RSASC ensures the K-coverage of each subregion from every group by randomly scheduling the sensors. We consider the target-coverage and area-coverage applications of WSN to analyze the usefulness of our proposed RSASC algorithm. The distinct quality of RSASC is that it utilizes less number of deployed sensors (33% less) to form the optimum number of MESSs with the higher computational speed (saves more than 93% of the time) as compared to the existing three algorithms.
