This paper is to study the decision of optimum ship size of 69G/T stow-net fishing vessel. The main task is to developed the basic design and economic analysis model by using the optimization techniques in terms of objective function and numerous constraints like : speed, fishing quantity, fishing range, CPUE (capacity per unit effort) and weight, ratio of main dimensions, etc. Therefore, in this paper, the process design of stow-net fishing boat is constructed with optimization of the design variables called the economic optimization criteria, and the objective function represents the criterion which is CBR(cost benefit ratio) such as the ratio of revenue/cost. The results are as follows. 1. It is developed the decision S/W of optimum ship size in 69 ton stow-net fishing boat which is constructed with optimization of the design variables called the economic optimization criteria. 2. The main demensions of optimum ship size of 69G/T stow-net fishing boat are obtained as L=25.1m, B=6.6m, D=2.57m, Cb=0.645, T/D=O.74, △(displacement) = 203ton, with voyage speed 11 knot ..

Dynamic compression plates, screws and K-wires, used in the orthopedic surgery as internal fixation system, should have excellent biocompatibility, corrosion resistance, and adequate mechanical properties. The present investigation was carried out in order to compare Seshin implants with Osteo implants of its biocompatibilities, mechanical and metallurgic properties by experiments both in vivo and vitro. The conclusions were follows: 1. In vivo, radiologic, hematologic results of domestic implants had no significant differences as compared with foreign made implants. 2. In vitro, metallurgic and physical properties of domestic implants had no significant differences as compared with foreign made implants. 3. In summary, it was concluded Seshin implants could be aplied to the human body, temporarily.

합병증이 동반된 Meckel씨 게실을 가진 환자의 치료에 대한 필요성은 과정이 문제이다. 하지만 우연히 만나는 게실의 처치는 논란 중이다. 부수적인 게실 절제술(incidental diverticulectomy)의 제안자는 증상이 있는 게실의 외과적 처치는 중요한 이환 및 사망률은 지적한다. 이를 반대하는 사람들은 전 생애를 통해 합병증의 위험성이 낮게 나타나므로 필요가 없다고한다. 게실의 예방적 제거는 개복술시 우연히 발견 될 때 시행한다. 이는 남아있는 게실이 나중에 합병증을 일으키는 것보다 술후 합병증의 위험성이 매우 적음을 알 수 있다. 저자들은 합병증이 동반된 Meckel씨 게실 2예를 경험하였기에 문헌 고찰과 더불어 보고하는 바이다. The necessity for therapy with complicated Meckel's diverticular is a matter of course.However, management of the incidentally encountered diverticulum is controversial. Proponents of incidental diverticulectomy point to the significant morbidity and mortality rates of surgical treatment of symptomatic divenicular. Other authors base their opposition to incidental diveniculectomy on the low risk of complications developing during lifetime. Prophyillctic removal of the diveniculum is indicated when it is found incidentally at laparotomy, because there are few postoperative complications and the risk exists that the remaining diverticulum may be the cause of later complication. The 2 cases of complicated Meckel's diverticulum are reported with a brief review of literature.

대형녹조류인 Ulva pertusa는 전 세계 연안에 서식하는 저서성 종으로 대발생 또는 인공구조물에 착생되어 경제적, 사회적인 측면에서 문제를 야기시키고 있다. 착생생물을 제어하기 위해 신방오제인 ziram, diruon, zinc pyrithione(ZnPT), copper pyrithione(CuPT), DBNPA, triclosan 등이 방오도료로 사용 중이나, 대형 및 미세조류를 이용한 신방오제들의 방오능 검증과 기초적인 연구자료가 부족한 실정이다. 따라서 본 연구에서는 초기 우점착생종인 구멍갈파래의 포자를 이용하여 방오제의 효능을 검증하고 생체막 형성의 우점종인 미세조류 Nitzschia pungens를 이용한 방오능을 검증하였다. 구멍갈파래포자의 운동성 검증에서 ziram과 ZnPT는 diuron, CuPT, DBNPA, triclosan보다 50% 높은 운동성 억제를 나타내었고 착생 검증에서는 ziram이 가장 낮은 착생률 1%로 나타났으며 CuPT는 100 ㎍/L의 농도에서 다른 대조군에 비해 80%의 성장율 억제를 보였다. 본 연구의 결과로 신방오제의 방오능을 검증하여 향후 방오능 검증에 기초자료가 될 것으로 사료된다. Cosmopolitan green macroalga, Ulva pertusa is a widely spread species in most coastal waters. This benthic alga is appearing on marine objectives causes significantly economical and social problems. To prevent fouling organisms, new antifouling (AF) agents, such as ziram, diruon, zinc pyrithione, copper pyrithione, DBNPA and triclosan are used. However, the evaluations of new antifouling system of those agents strongly need more information on algae species for considering environment effect. Therefore, the purpose of this study was to evaluate the activity of antifouling system using Ulva spores and Nitzschia pungens. In addition, new AFS were evaluated the toxicity of microalga, Nitzschia pungens. In the motility of Ulva spores, ziram and zinc pyrithione were shown 50% higher inhibition motility than diuron, copper pyritione, DBNPA and triclosan. Ziram was appered the highest AFS of Ulva sore attachment. Copper pyrithione at the concentration of 100 ㎍/L was inhibited 80% growth rate comparison of control. In conclusion, each new AF agents showed their specific AF activities against marine organisms based on this work.

Spore attachment of Ulva fasciata on agar and agaroses coating films showed various surfaces properties according to concentrations of agar or agaroses or via methanol. The highest number of spore attachment occurred in Sigma agarose coating film. Spore attachment on Bacto agar and other agaroses coating films showed the (2∼36 times less than Sigma agarose coated film. Comparison of spore attachment on 2.5% and 5% SeaKem agarose and Bacto agar coating films differed in two concentrations while coating of 2.5% and 5% with NuSieve and Sigma agaroses did not differed. Spore attachment of coating made of 5% and 5% via 4% MeOH with Bacto agar and NuSieve agarose only differed. Overall, these results indicated agar and agarose coating films differed in spore attachment. Results of this work will be useful baseline for bioassay of antifouling activity of fouling organisms.

As a comprehensive study on the development of curriculum for environmental education based on the standpoint of ecology, the environmental issues within the science textbooks used in the elementary, middle and high school were analyzed with the special emphasis to four aspects; 1) the causes and 2) the examples of environmental pollution, 3) the principles of ecology, and 4) the endeavor to overcome environmental crises. The results confirm that the science textbooks were written on the basis of Environmentalism rather than Ecology, and the environmental issues were listed fragmentarily within the subjects related to science, and not systematically assembled between inter-subjects or -sciences. Therefore, the systematic and inter-scientific approaches based on the ecology will be needed for further and better environmental education. [environmental education, ecology, textbook analysis].

Catastrophic antiphospholipid syndrome is a highly fatal condition characterized by widespread thromboembolism subsequent to a triggering factor (e.g., infection, trauma, and neoplasia) in antiphospholipid antibody-positive patients. This paper reports a case of a 29-year-old male without the underlying disease who developed extensive mesenteric thromboembolism and jejunal necrosis during the treatment for acute enteritis. The patient’s condition was improved with low-molecular-weight heparin and an intravenous Ig treatment with emergency surgery. The serum antiphospholipid (anticardiolipin IgM) and lupus anticoagulant antibody tests showed positive results. Acute infectious enterocolitis is generally considered a mild disease. On the other hand, aggressive evaluation and treatment should be considered if the clinical conditions do not improve and deteriorate rapidly despite appropriate antibiotic treatment because of the possibility of acute immunological complications, such as catastrophic antiphospholipid syndrome.
