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.

저자는 1977년 1월부터 1982년 8월까지 5년 8개월간 경북의대 부속병원 소아과에 알레르기성 자반증으로 입원하였던 환아 36예를 대상으로 하여 다음과 같은 성적을 얻었다. 성별 분포는 남녀 각각 50%로서 차이가 없었고 계절별 분포는 상기도감염이 빈번한 봄, 겨울이 72.2%를 차지하였으며, 선행질환으로서는 상기도 감염이 69.4%에서 인지되었고 알레르기성 병력을 가진 환아는 13.9%였다. 임상증상은 피부병변이 100%, 위장관계 증상이 88.9%, 관절증상이 61.1%에서 나타났었다. 신장침범은 33.3%였으며 현미경적 혈뇨가 1예, 현미경적 혈뇨 및 경도의 단백뇨가 3예, 현미경적 혈뇨 및 심한 단백뇨가 2예였다. 육안적 혈뇨 및 경도의 단백뇨는 1예, 육안적 혈뇨 및 심한 단백뇨는 4예가 있었으며, RPGN이 1예였다. 이중 6예에서 신생검을 시행하였으며, 2예는 경도의 병변을 보였고 나머지 4예는 모두 반월체를 형성하는등 심한 병변을 보였다. RPGN 경과를 취한 1예는 사망하였다. 신침범과 이와 관련된다고 생각되는 인자들, 즉 5세 이상의 연령군, 성별, 위장관증상의 경중, 관절증상의 유무, 재발유무 등과의 관계를 살펴본 결과 신침범을 일으킨 환아에서 심한 위장관증상 및 재발율이 다소 높게 나타났으나, 통계적 처리로서는 특별한 의의가 없는 것으로 나타났다. A clinical observation has been made on 36 children with Henoch-Scho¨nlein perpura who were admitted to pediatric department of KNU hospital from January 1977 to August 1982. Rate of male to female patients was 1:1, and the majority of cases developed illness during spring and winter months. URI was noticed as preceding illness in 69.4% of cases, and allergic history was elicited in 13.9%. Clinical manifestations showed involvement of skin in 100%. GIT in 88.9%, joint in 61.9% and kidney in 33.3%. Out of 12 cases in whom nephritis developed, 1 case showed microscopic hematuria, 3 cases microscopic hematurai with mild proteinuria, 2 cases microspic hematuria with heavy proteinuria, 1 case macroscopic hematuria with mild proteinuria, 4 cases macroscopic hematuria with heavy proteinuria and 1 case RPGN. Percutaneous renal biopsy performed on 6 cases revealed minimal change in 2 cases and severe renal involvement with crescent formation in 4 cases. Relationship between renal involvement and other parameters including age grou over 5 years, sex, severity of GIT symptoms and presence of recurrence showed somewhat high incidence of severe GIT involvement and presence of recurrence in patients with renal involement. However statistical analysis showed no significant difference.

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.

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.

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.

김근배,손홍주,이상준 부산대학교 유전공학연구소 1995 분자생물학 연구보 Vol.11 No.-

Polyhydroxyalkanoic acid(PHA)를 생산하는 세균들을 하수처리장의 활성오니로부터 존화배양에 의하여 분리하였다. 이들 중 단일기질로부터 PHA를 생산하는 균주의 생리학적 성질을 검토한 결과 Alcaligenes 속으로 동정되었다. 균체 생육에 최적인 배양온도, pH는 각각 36℃, pH6.8로 나타났으며, 탄소원으로 과당 10g/l, 질소원으로 polypeptone 5g/l, Na_2HPO_4 1×10^-2 M, KH_2PO_4 1.3×10^2 M이었다. PHA 합성을 위한 최적조건을 조사하기 위하여 2단계 배양법을 이용한 결과, 배양온도 36℃, pH6.8, C/N 비 50이 PHA 합성에 최적인 것으로 나타났다. 탄소원을 간헐적으로 첨가하는 유가배양에 의하여 배양 60시간만에 건조균체량 17.4g/l, PHA 9.1g/l를 얻을 수 있었다. 추출, 정제된 PHA는 NMR에 의하여 분석한 결과 PHA/HV copolymer 임을 확인할 수 있었다. For polyhydroxyalkanoci acid (PHA) production, several microorganisms were isolated from sewage sludge. One of them, GB-77 strain, was chosen from its PHA/HV copolymer production on only fructose without cosubstrate. The isolated strain GB-77 was identified as the genus Alcaligenes. Optimal temperature and pH for cell growth were 36℃ and 6.8. Optimal medium composition was 10 g/l of fructose and 5 g/l of polypeptone, 1×10^-2 M Na_2HPO_4, 1.3×10^-2 M KH_2PO_4. To investigate the optimal condition for polyhydroxyalkanoic acid production two-stage culture technique was used; first stage for cell grown and second stage for PHA production on unbalanced growth conditions. Optimal conditions for high PHA production were C/N ratio 50, temperature 36℃ and pH 6.8. To overcome frutose inhibition on cell growth, intermittent feeding fed-batch culture technique was used. Total cell concentration was 17.4 g/l with 9.1 g/l of PHA. The purified PHA was identified PHA/HV copolymer by NMR analysis.

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.
