The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based o the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

Lipoprotein(a)와 대동맥판막과 승모판막 경화증 및 복부 대동맥 두께의 상관관계에 대한 연구

김민수,유근배,이상운,임양희,신길자,조홍근 梨花女子大學校 醫科大學 醫科學硏究所 1998 EMJ (Ewha medical journal) Vol.21 No.3

연구배경 : Lipoprotein(a)의 농도와 대동맥판막의 두께, 승모판막의 두께 및 복부 대동맥의 두께와의 관계에 대하여 조사하고, 다른 관상동맥질환의 위험인자와의 관계를 규명해 보고자 하였다. 대상 및 연구방법 : 1995년 6월부터 1996년 5월까지 이화여자대학교 의과대학 부속 동대문병원에서 심초음파검사를 시행하였던 환자 116명을 대상으로 하였으며 이중 급성심근경색증, 갑상선질환 및 혈청 지질치에 영향을 미치는 약제를 복용중인 환자를 제외하였다. 성별, 나이, 고혈압의 유무, 흡연유무 및 혈청 콜레스테롤, 고밀도지단백콜레스테롤, 중성지방, 저밀도지단백콜레스테롤, lipoprotein(a)치를 측정하였고, 미국 휼레트 패커드사의 Sono 1000 을 이용하여 대동맥판막의 두께, 승모판막의 두께 및 대동맥의 두께를 측정하였다. 결과 : 1) Lipoprotein(a)는 남자가 34.6±34.3mg/dl, 여자가 25.6±23.4mg/dl 이었으며, 총 콜레스테롤, 저밀도 지단백콜레스테롤 및 고밀도지단백콜레스테롤, 중성지방에는 남녀간에 유의한 차이가 없었다(p>0.05). 2) Lipoprotein(a) 농도와는 대동맥판막의 두께만이 의의있는 양의 상관관계를 보였으며, 승모판막의 두께, 복부대동맥 두께 및 상행 대동맥의 내경과는 관계가 없었다. 3) Lipoprotein(a)와 일반 특성 및 생화학적인 특성과의 관계에서 Lipoprotein의 농도는 오직 흡연과 관계가 있었으며(p<0.01), 혈압, 연령, 총콜레스테롤, 중성지방, 고밀도지단백콜레스테롤 및 저밀도지단백콜레스테롤과는 무관하였다. 4) 18명의 환자에서 관상동맥조영술을 실시하여 관상동맥질환의 유무 및 정도와 대동맥 판막두께와의 관계를 분석한 결과 대동맥 판막이 두꺼울수록 관상동맥질환의 정도가 심했다(p<0.01). 결론 : 본 연구에서 lipoprotein(a)농도와 대동맥 판막의 두께가 의의있는 양의 상관관계를 보였으며, lipoprote-in(a)의 농도는 흡연력만 관계가 있었다. 또한, 대동맥 판막이 두꺼울수록 관상동맥 질환의 정도가 심한 것을 볼 때, lipoprotein(a)의 농도 및 대동맥판막의 두께가 관상동맥 질환의 위험인자가 될 것으로 생각된다. Background : An elevated serum lipoprotein(a) level is an independent risk factor for athe-rosclerotic diseases, and the lipoprotein(a) level is correlated to preclinical atherosclerosis. To evaluate the association between lipoprotein(a) and aortic selerosis, ,itral sclerosis, and abdominal aorta thickness, we measured the aortic valve thickness, mitral valve thickness and abdominal aorta thickness. Also, we assessed the relationship between the aortic valve sclerosis, mitral valve sclerosis, abdominal aorta thickness and other coronary risk factors. Method : We measured serum lipoprotein(a) in 116 patients(52 men, 64 women) with mean age of 58.7±13.9 years. Aortic valve thickness was assessed by parasternal long and short axis two dimensional echocardiography, mitral valve thickness was measured by apical 4 chamber view. The abdominal aorta thickness was measured by the subcostal view. Result : The level of lipoprotein(a) was significantly correlated with the aortic valve thickness, but not with the miral valve thickness and the abdominal aorta thickness. lipoprotein(a) level was higher in smoking patients(p<0.05), and not related to other ariables such as blood pressure, age, total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein. Coronary angiography was performed in 18 paitents, and there was a tendency of the coronary artery disease with high level of the lipoprotein(a)(p<0.005). There was no significant difference in the thickness of aortic valve in terms of sex, blood pressure, total cholesterol, high density lipoprotein, triglyceride or blodo sugar. Conclusion : We conclude that increased serum levels of lipoprotein(a) are closely related to aortic valve sclerosis and may be a risk factor for coronary artery disease.

金建培,柳洪秀 군산대학교 1982 群山水産專門大學 硏究報告 Vol.16 No.3

In this study, changes in water holding capacity(W.H.C.), drip and tenderness of frozen chicken meat treated with various pretreatment condition were carried out in comparision with controlled meat, in order to investigate the deterioration occurred in cold storage for periods within 90 days. The results were as follows; 1.Water holding capacity was showed the higher stability in glazed meat(T3) and cured meat(T4) as comparision with those of controlled meat(T1) or packaged meat(T2). 2.The maximum percentage of free drip from samples was resulted in T1 group(9.5%), while the minimum was noted in T4 group(3.6%). 3.It was revealed that the expressible drip from samples were increased from 1.8%(T4 group) to 4.3% (T1 group). 4.It can be observed that the highest tenderness expressed as penetration value was showed in T4 group(151). The tenderness of T2 and T3 group were raised significantly for the cold storaging periods between 30 days and 60 days. But in case of T1 and T4 group, the same tendency was observed from 60 days to 90 days.

Naphthalene sublimation technique is employed to investigate the heat transfer enhancement of fin-tube heat exchangers using vortex generators. Experiments are performed for the fin-circular tube heat exchanger with and without vortex generators, and fin-flat tube heat exchanger with and without vortex generators. Local and spanwise averaged heat transfer coefficients are measured on the surface of fin, and compared with those obtained without vortex generator. Average heat transfer coefficients of fin-flat tube heat exchanger are much lower than those of fin-circular tube heater exchanger. On the other hand, fin-flat tube heat exchanger with vortex generators has a little higher heat transfer value than fin-circular tube with vortex generators. Friction loss for four types of heat exchanger are also measured and compared.

It is getting more important to obtain safety and comfort in buildings. Due to the economic development and the change in life style, various criteria such as human life as well as the means of wealth and social infrastructure should be protected against fire risks. The present study aims to survey the fire protection facilities of multi-dwelling residence, office and commercial buildings. The fire evacuation plan of buildings were analyzed and the defected fact with high fire risks were evaluated. Also a method to minimize the lost from fire was suggested and practical fire alarm an fire detection plan were also commented.

김영완,이상윤,김홍배 여수대학교 1998 論文集 Vol.13 No.2

For the optimal design of plasma facing components of a fusion reactor, the thorough understanding of thermal behavior of high heat flux components are required. The purpose of this research is to investigate the characteristics of heat flow and thermal stress in divertors which are exposed to high heat load varying with time and space. Numerical simulations of heat flow and thermal stress for three types of divertor are performed using finite volume method and finite element method. Respectively, commercial FLUENT code are used in the heat flow simulation, and maximum surface temperature, temperature distribution and cooling rate are calculated. Commercial ABAQUS code are used for calculating temperature distribution, thermal stress, strain and displacement. Through this computer simulation, design data for cooling system and structural are provided.
