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.

김진영,배성미,홍경자,라현오,김양리,강문원 한국병원약사회 1999 병원약사회지 Vol.16 No.1

In order to find out whether ceftriaxone, a third generation cephalosporin antibiotics, is used appropriately, safely and effectively, DUE study was conducted by reviewing 70 charts of patients who were treated at Kangnam St. Mary's hospital from Oct. 1997 to Nov. 1997. The DUE criteria was modified from the criteria on ceftriaxone use established by American Society of Health-System Pharmacists. As a result, 33 cases (47.2%) were met with criteria for the justification of use. The analysing process indicators including CBC, SCr were taken before the initial dose and the vital sign monitoring were relatively well documented showing the accepted levels of above 80%. On the other hand, blood sampling for the culture and sensitivity test before the initial antibiotic dose WBC Count, SCr, LFT during the therapy were in low accepted levels. As an outcome analysis, the result of blood culture after discontinuing drug were documented with accepted level of 24.3%. As a conclusion, it is suggested that above finding should be communicated to the medical staff, and an active intervention, such as feedback control system by pharmacist, also be necessary for the rational medication use.

MOS FET에 있어서 Hot-Electron 放出電流의 解析

金弘培 淸州大學校 1982 論文集 Vol.15 No.2

This paper discusses the analysis of Hot-Electron emission current in MOS FET using the numerical method. The discussion begins with Hot-Electron emission current Model and use the normal MOSFET and LDD (Lightly Doped Drain). The emission probability is a function of substrate doping profile, substrate voltage, gate voltage, and lattice temperature. It is shown how LDD can be used to reduce the Hot-Electron emission current.

상 이동 촉매를 이용한 할로겐화 옥틸과 아지드화 나트륨과의 반응속도에 관한 연구

金昌培,金鍾奎 단국대학교 1986 論文集 Vol.20 No.-

Rates of reaction between chloro and bromooctane and NaN_3 in the presence of quaternary ammomum salts were determined. Second order rate constant for the reaction between ch1orooctane and NaN_3 was 1.31×10 exp(-4) M^-1sec^-l at 85℃ when Aliquat 336, trioctylmethylammonium chloride was used as a catalyst, and values are only slightly increased as the concentration of NaN_3 was increased. In the case of 1-bromooctane, (C_4H_9)_4 NBr was used as a catalyst. First order constants were found to increase more steeply as the concentration of NaN_3 increased. Different behaviors of two catalysts were discussed by comparing with the earlier results from cyanide exchange reactions. Also, it was pointed out that aliquat 336 was a very good catalyst for the synthesis of alkyl azide.

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.

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.

A 110 mm diameter aspheric metal secondary mirror for a test model of an earth observation satellite camera was fabricated by ultra-precision single point diamond turning(SPDT). Aluminum alloy for mirror substrates is known to be easily machinable, but not polishable due to its ductility. A harder material, Ni, is usually electrolessly coated on an Al substrate to increase the surface hardness for optical polishing. Aspheric metal secondary mirror without a conventional polishing process, the surface roughness of Ra=10nm, and the form error of Ra=λ/12(λ=632.8nm) has been required. The purpose of this research is to find the optimum machining conditions for reflector cutting of electroless-Ni coated Al alloy and apply the SPDT technique to the manufacturing of ultra precision optical components of metal aspheric reflector.
