강원도 춘천시를 중심으로하는 북한강 상류는 수도권에 청정 상수원류를 제공하는 생활의 핏줄이다. 또한 수도권 지역 건설에 필수적인 석재 자원의 주요 공급 지역으로 알려져 있다. 본 연구에서는 이 지역의 보존과 체계적 개발을 위한 지리정보처리 기술을 이용한 천연자원 종합관리 시스템을 개발하였다. 이 시스템은 자원관리를 위한 막강한 도구와 기능 예를 들면 정보수집, 편집, 처리, 모델링, 분석 및 가시화기능을 제공한다. 결과적으로 이 시스템은 지하자원 분석, 천연자원의 기획 및 개발, 자연보호 등 자원관리와 연계된 문제를 효율적으로 해결할 수 있는 능력을 제공하고 있다. The upper stream area of the north Han river, which is located around the Chunchon city of the Kangwon province, is out essential resources, which supply clear drinking water to the capital city of out conutry, Seoul. This area has also produced stone and aggregate resources required for building and road constructions in the capital area For preservation and planned-development of this area, in this study, we have developed an integrated management system for natural resources, based upon geological information technologies. This system includes powerful tools and functions for resource management such as information collection, edition, processing, modeling, analysis, and visualization. As a result, this system may give us capabilities to efficiently handle a variety of resource management issues such as the analysis of underground resources, the planning and development of natural resources, the protection of environment and their related projects.

Ordinarily stow net fisheries was used by floater beam and sinker beam for the purpose of spreading the mouth of net. But it was not only iuconvenient and dangerous but much defective. In this thesis, we have studied fundermental experiment of the improved stow net fishing gear using head rope, ground rope and otter sail instead of floater beam and sinker beam. From the result of this experiment, it has been succeeded for fishing work to achieve basically without any difficulty. The results obtained in this study were as follows. 1) The resistance of fishing gear was estimated R≒7V2 as possible as it is taken greatly. (R: Resistance V: the rate of current) 2) The interval of otter sail was spreaded smoothly. Being in normal condition, it was maintamed the width 37-38m. It was heared comparison with net mouth of ordinary gear, and the shearing force was enough. 3) The height of mouth was lower than we have anticipated to and seemed to have the supplement of buoyancy. But according to increasing the rate of current, the lowness of mouth height was little affected. 4) The height of otter sail was decreased at the rate of 30% by the rate of current, on the contrary, the height of wing was not decreased owing to sufficient buoyancy, 5) The adjustment of extention length of hanging wire(connected with fishing boat) and raising wire(with otter sail) was great important problem and it must be dealed with the most moderatly because of a corelation between the spreading of fishing gear and catching ability. 6) On the depth of 30m, it was taken 25 minuits to cast anchor and lines, 20 min cast net, 24 min haul net, 45 min haul lines and heave anchor, respectively. 7) The improved stow net with otter sail was cleared up the defects and difficult problems in ordinary gear using floater beam and sinker beam, and it have more advantages of fishing work than ordinary one. But there were involved in lots of problems in details to solve in the future.

In order to develop the curriculum of the fishery department in the fisheries Jr. college, We have collected and analyzed the domistic and foreign data adquated to the fishey department under the international trend, also we gathered the opinion from the inquiring paper investigation and consultation to the industrial field, concerned college and graduate during the 6 month from September 1982. The fishery department curriculum in fisheries Jr. college will be industrialized with the concerned technics and knowledge in relation to speciality of maritime affairs. Accordingly, we have developed the adquate curriculum which is practical and can be cultivated the technician to adopt in the industrial society.

강원도는 오랫동안 금속, 비금속, 석재 및 석탄과 같은 지하자원들을 공급하는 국내 주요생산지로 알려져 왔으나, 장기적인 채광과 비 계획적인 생산으로 인하여 매장량이 고갈되고 있으며, 대외적으로 생산 경쟁력 마저 잃어가고 있다. 이러한 문제점에 대한 해결방안의 일환으로 본 연구에서는 강원도내에 산재되어 있는 지하자원의 분포, 자원 생산시설 및 생산량, 경제성, 자원개발, 환경문제 등 자원관리에 필요한 제반사항을 수행할 수 있는 강원지역 자원 종합관리 GIS 시스템을 개발하였다. 이 시스템의 개발은 방대한 양의 정보 조사 및 저장, 오랜 개발기간, 많은 소요인력 및 개발 비용이 요구되기 때문에 본 연구에서는 조기에 자원관리 GIS 시스템을 개발하여 이와 관련된 생산 및 연구 분야에 조기에 적용할 수 있도록, 일차년도에는 현재 석재복합 신소재제품 연구센터의 집중적 연구대상 지역인 태백지역에 대한 탄광지역을 중심으로 자원 종합관리 GIS 시스템을 개발하였다. The Kangwon province has been well-known to be one of major underground resource producing districts which are mainly supplying metals, non-metals, stones, and coals. However, due to the long-term mining and unplanned production, the natural resource reserves have been rapidly drained and oversea production competition has been losing. In this study, we has developed a GIS system for regional resource management in the Kangwon province, which can operate, maintain, and manage the distribution of underground resources, resource production facilities, production and economic development, and environmental issues. The development of this system requires the collection, analysis, evaluation, and storage for a huge amount of research data, and in addition, the long period of time, the big research man power, and big development cost. Accordingly, to shorten the development period of time and to early apply itself to production, this stage of study has been intensively developed a regional resource GIS system for managing the mines scattered in the Tabak province, which is one of hottest RRC's research areas.

<P>Poloxamer-modified liposomes (PMLs) were prepared using poloxamers (P85 and F68) by the thin-film hydration method for overcoming the multidrug resistance and thereby enhancing the intracellular uptake of specific substrates of P-gp, rhodamine 123 (R123). The prepared liposomes, plain liposomes (PLs) and PMLs, were characterized by particle size, zeta potential and drug entrapment efficiency, and assessed by <I>in ?vitro</I> cellular uptake using KB and KBV20C (P-gp over-expression cell line) cells. The transmission electron microscopy study revealed the spherical shape of the prepared liposomes. No significant difference was observed between the PMLs and liposome without poloxamer (PLs) in the particle size (∼??60 ??nm) and zeta potential (∼??minus;??5 ??mV). The <I>in ?vitro</I> cellular uptake study showed that P85-modified liposomes (PML-P85) significantly increased the internalization of R123 in MDR tumour cells. Our results showed that PML-P85 could be an effective carrier for anticancer drugs in MDR cancer therapy.</P>

Purpose: Bleeding is one of the most serious complications of advanced gastric cancer (AGC) and is associated with a poor prognosis. This study aimed to evaluate the clinical outcomes of endoscopic hemostasis for bleeding in patients with unresectable AGC. Materials and Methods: This study included 106 patients with bleeding associated with gastric cancer who had undergone endoscopic hemostasis between January 2010 and December 2013. Clinical characteristics, treatment outcomes, including rates of successful endoscopic hemostasis and rebleeding, risk factors for rebleeding, and overall survival (OS) were investigated. Results: Successful initial hemostasis was achieved in 83% of patients. Rebleeding occurred in 28.3% of patients within 30 days. The median OS after initial hemostasis was lower in patients with rebleeding than in those without rebleeding (2.7 and 3.9 months, respectively, P=0.02). There were no significant differences in disease status and rebleeding rates among patients with partial response or stable disease (n=4), progressive disease (n=64), and first diagnosis of disease (n=38). Univariate and multivariate analyses (P=0.038 and 0.034, respectively) revealed that transfusion of ${\geq}5$ units of RBCs was a significant risk factor for rebleeding. Conclusions: Despite favorable success rates of endoscopic hemostasis for bleeding associated with gastric cancer, the 30-day rebleeding rate was 28.3% and the median OS was significantly lower in patients with rebleeding than in those without rebleeding. Massive transfusion (${\geq}5$ units of RBCs) was the only significant risk factor for rebleeding. Patients with bleeding associated with AGC who have undergone massive transfusion should be observed closely following endoscopic hemostasis. Further research on approaches to reduce rebleeding rate and prevent death is needed.
