최근 중국은 양산항을 개장하여 선사 유치를 위한 다양한 혜택을 제공하고, 일본은 "수퍼중추항만 육성계획“을 세워 항만의 효율성을 바탕으로 비용을 낮추려는 노력을 하고 있다. 또한 선박의 대형화에 의한 중심항만(Hub Port) 위주의 기항과 북중국의 대량 물량 발생지역에 대한 직기항 경향으로 동북아 항만간의 경쟁이 더욱더 치열해 지고 있으며 동북아 역내 피더네트워크 강화의 필요성이 제기되고 있다. 따라서, 본 연구에서는 유럽 피더네트워크 전략 사례를 바탕으로 동북아 피더시장 현황을 파악하고 동북아 피더네트워크 구조를 분석함으로써 동북아 역내 항만 및 선사간의 과당경쟁을 지양하고 서로 Win-Win할 수 있는 터미널의 전략적 활용, 선사간 제휴 확대, 항만간 협력 강화를 위한 구체적인 전략을 제시하였다. Recently, China opened Yangshan port and provides a variety of benefits for shipping companies. Japan plans to reduce logistics costs and improve efficiency through the established "super major ports" project. According to the "hub and spokes" system, the number of direct calls toward North-Chinese ports are increasing. This changing environment has negative effects on the amount of transshipment cargos in Korean ports. In order to make a hub port of a domestic port, it is necessary to develop northeast Asian feeder networks. Therefore, this paper analyzes the structure of northeast Asian feeder networks through the case study of European feeder networks strategy. Finally, we suggests the plans to reinforce feeder networks, which are strategic terminal operation, strategic alliances between shipping companies and port co-operation, for win-win strategy in the competitive northeast Asian market.

Objectives : In 2002, the Korean Medication Algorithm Project for Major depressive Disorder (KMAP-MD) was published, but there has been a need for a guideline about detailed issues of depressive disorder. We revised KMAP-MDD andreestablished Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2006. Methods : A questionnaire had been developed by the executive committee for KMAP-DD. The review committee consisted of 101 experienced psychiatrists. From the total of 22 questions in the questionnaire, 7 questions were evaluated for these subjects . We classified the expert opinions to 3 categories according to its confidence interval; first, second and third line. Results : SSRI and venlafaxine were the first line antidepressants (AD) for atypical and melancholic depression. For dysthymic disorder and minor depressive disorder, SSRI was recommended as the first line medications. Only AD medications was a preferred initial strategy for treating premenstrual dysphoric disorder, mild to moderate and severe non-psychotic postpartum depression. In severe psychotic postpartum depression, combination therapy of AD and atypical antipsychotics was the treatment of choice. SSRI was preferred when considering sedation, anticholinergic and cardiovascular adverse effects. Also, experts recommended mirtazapine against gastrointestinal adverse effects and bupropion in avoiding sexual dysfunction. Conclusion : These results suggest that clinicians have to consider both clinical situations and drug adverse effects in the choice of antidepressant medications.

全泰玉,周原植,金福仁,崔병국,吳世旭 東亞大學校 1980 東亞論叢 Vol.17 No.2

Austenite stainless steel 년 316 has heat treated to austenite structure by heating at 1100℃ for 1hr and suddenly cooling. These specimens has been dealed with aging treatment at 700℃ for 0hr, 2hr, 10hr, and 100hr separately, and then conducted by creep test on the uniaxial state of stress in atmosphere of 600℃. The experimental results are obtained as follows. 1) Creep rupture stain rate has increased by the increasing of aging time. 2) Creep rupture time have had large affect of aging time comparing with 0hr aging specimen and increased by 20%, 40%, and 60% separately for 2hr, 10hr, and 100hr aging specimen. The empirical formulas of creep rupture time "t" as follows. (aging time are in parenthesis) t?=2.297×10? t?=8.810×10? t?=2.951×10? t?=1.178×10? 3) Creep constant "n" has increased, "k" decreased and creep limit increased by increasing the aging time. Then creep strain rate has decreased and increased by increasing the aging time and stress. The empirical formulas as follows. ε?=3.326×10? ε?=1.905×10? ε?=1.347×10? ε?=3.465×10? 4) The creep strain rate multiplied by creep rupture time has constant value according to property of material and belongs to the range of parallel line at logarithmic graph paper. 5) Hardness has increased by the increasing of aging time and intergranular hardness is higher than transgranular hardness. 6) The micro cracks occur from wedge crack and cavitation crack at grain boundary and exist at the surface of specimen and the surface of longitudnal section. 7) High stress and aging specimens have mostly wedge crack. Low stress and nonaging specimens have mostly cavitation crack. 8) Rupture surface of higher stress has shearing fracture of about 45° inclination, and has tendency of fracture by directing perpendicular to the axis for decreasing creep stress and also has same phenomenon for occurrence and propagation of crack.

Cyclohexane에 의한 흰쥐의 폐독성

전태원,이상일,윤종국 대한의생명과학회 2000 Journal of biomedical laboratory sciences Vol.6 No.4

Cyclohexane에 의한 생체장기의 독성을 검토할 목적으로 휜쥐에 체중 kg당 1.56 g의cyclohexane을 복강으로 1일 1회 2일 간격으로 4회 투여한 다음 24시간 후에 처치하여 각 장기 (간,신장, 비장, 심장, 소장, 위 및 폐)의 체중 당 장기무게 (%)와 조직세포중 glucose-6-phosphatase (G6Pase) 활성변동을 측정한 결과, 실험군의 체중 당 폐무게가 대조군에 비하여 현저하게 증가 (p<0,001)하였고 이와는 반대로 G6pase 활성은 유의한 (p<0.001) 감소를 나타내었다. 그러나 폐를 제의한 장기에서는 별다른 차이를 볼 수 없었다. 이러한 결과는 cyclohexane이 주로 폐조직에 독작용을 야기시킨다는 것을 시사해 주고 있으며, 폐조직에서 malondialdehyde 함량이 대조군에 비하여 유의하게 (p<0.05) 증가된 것이 이를 뒷받침 해 주고 있다. 한편, cytochrome P450에 의해 나타나는 aniline hydroxylase활성은 폐조직이 간조직에 비하여 대단히 낮았으며, alcohol dehydrogenase (ADH) 활성 역시 간조직 보다 현저하게 낮게 나타났다. 그리고 cyclohexane투여로 인하여 ADH 활성은 간 및 폐조직 모두에서 증가하였으나 간조직에서 더욱민감한 반응을 나타내었다. 이상 실험결과를 종합해 볼 때, cyclohexane은 폐조직에 주로 독성을 나타 내며 이는 간조직에서 대사된 cyclohexane의 독성 중간대사산물인 cyclohexanone이 혈류를 통해 폐조직에 분포되어 나타난 결과로 사료된다. In order to search the target organ of cylclohexane toxicity, the rats were intraperitoneally treated with cyclohexane (1.56 g/kg of body wt.) four times every other day. In the increasing rate of organ weight per body weight (%) in cyclohexane-treated animals, the lung was highest among the liver, spleen small intestine, stomach, heart and kidney. And in the decreasing rate of glucose-6-phosphatase (G-6-Pase) activity in each organ that of lung was also highest among all organs. Lung MDA content was significantly increased (p<0.05) by the cyclohexane treatment. On the other hand, microsomal aniline hydroxylase activity in lung tissue both of control and cyclohexane-treated rats was greatly low as could be scarcely measured, but that in liver possessing high activity was significantly increased (p<0.05) in cyclohexane-treated rat compared with control. Alcohol dehydrogenase activity in lung was markedly higher than that of liver and the latter was significantly (p<0.05) increased by the cyclohexane treatment. In conclusion, cyclohexane treatment to the rats showed mainly lung toxicity and it may be responsible far cyclohexanon, cyclohexane metabolite, distributed from liver.

전태원,이병근 師範大學 體育硏究所 1992 서울大學校 體育硏究所論集 Vol.13 No.1

The purpose of this study was to evaluate the differences between grade in the cardio-respiratory function variables of male elementary, middle, high school and college students. By open circuit method(Douglas bag method) 92 subjects (elementary, 24; high,24;college,20) performed maximal treadmill work with Bruce protocol to examine VO₂max and other the aerobic capacity variables. In statistical analysis, oneway-ANOVA was proceeded for comparing and analyzing the differences between grade of subjects. From the upper statistical procedure, the results were made as follows; 1. Maximal oxygen uptake (VO₂max) There was significant VO₂max difference between elementary, middle, high school and college students(1.446, 2.396, 2.887, 2.785ℓ/min; p<.01). 2. Maximal oxygen uptake in relation to body weight (VO₂max/㎏) There was no significant difference between elementary, middle, high school and college students (48.4, 45.8, 46.2, 44.4ml/㎏/min; p>.05) 3. Maximal oxygen uptake in relation to fat free weight (VO₂max/FFW) There was significant difference between elementary, middle and high school students (63.6, 60.7, 51.4ml/㎏/FFW; p<.01)> 4. Maximal ventilation (V?) There was significant difference between elementary, middle, high school and college students (57.7, 89.7, 108.3, 96.8ℓ/min;p<0.01). 5. maximal Oxygen ventilation equivalent (VEO₂) There was no significant difference between elementary, middle, high school and college students (40.3, 38.1, 37.7, 36.3; p=.15) 6. maximal Oxygen pulse (O₂pulse) There was significant difference between elementary, middle, high school and college students (7.6, 12.2, 14.4, 14.7ml/beat; p<.01). 7. maximal heart rate (max HR) There was significant difference between elementary, middle, high school and college students (195.5, 199.1, 200.4, 191.8 beats/min; p<.01).

Selective hydrogenation of 1,3-butadiene in C4 raffinate was carried out in fixed bed reactor using Pd/a1unina catalysts, Concentration of 1,3-butadiene in C4 raffinate could be reduced under 100 ppm.The life of dimerization catalyst using C4 raffinate after selective hydrogenation was longer than that of dimerization catalyst without selective hydrogenation.It was found that dilution of olefin concentration in feed was effective to increase dimerization catalyst life.

흰쥐에 Xylene 반복 투여가 Xylene의 대사에 미치는 영향

전태원,이혜자,윤종국,이상일,조현국 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1999 Journal of biomedical laboratory sciences Vol.5 No.1

실험동물에 xylene의 반복 투여가 이물질의 대사에 어떠한 영향을 미치는지를 알아보기 위하여 흰쥐에 m-xylene과 olive oil의 동량혼합액을 체중 100g당 0.25ml씩 2일 간격으로 1, 4, 8, 12 및 16회 복강으로 투여한 다음 마지막 투여 24시간 후에 처치하여 다음과 같은 결과를 얻었다. 요 중 m-methylhippuric acid 함량은 m-xylene 4회 투여군의 경우 1회 투여군에 비하여 약 56%의 유의한 증가를 보였으며 이후 12회 투여까지 유사한 결과를 나타내었으나 m-xylene 16회 투여시에는 xylene 1회 투여군 치와 유사한 치로 감소되었다. 그리고 간조직의 microsomal aniline hydroxylase와 alcohol dehydrogenase 활성은 m-xylene 12회 투여시 까지는 대체적으로 점진적인 증가를 보였으나 이후 16회 투여시에는 12회 투여군에 비하여 유의한 감소를 보였다. 또한 aldehyde dehydrogenase 활성은 m-xylene 투여 회수에 비례해서 전 실험기간 동안 감소되었으며 특히 16회 투여군에서 본 효소활성의 현저한 감소를 보였다. 한편 본 실험조건에서 투여기간에 따른 진자현미경적 미세구조의 변화는 초기에 활면소포체의 증식이 보이다가 16회 투여군에서는 활면소포체가 감소되고 조면소포체가 증가되었다. 이상 실험결과는 흰쥐에 있어서 xylene 투여 회수에 따라서 요 중 m-methylhippuric acid의 농도 변동이 초래되며 이는 효소단백 유도에 따른 xylene 대사효소 활성 변동에 기인된 결과로 생각된다. To evaluate the effect of repeated treatment of xylene on its metabolism, m-xylene (0.25ml of 50% in olive oil/100 g body weight) has been intraperitoneally given to the rats 1, 4, 8, 12 and 16 times every other day. m-Xylene was once more administered to the animals after 24 hrs since last injection of it. And then the animals were sacrificed after 24 hrs. Four times xylene treated rats showed the significantly elevated urinary m-methylhippuric acid, compared to those treated with the singe dose of m-xylene with the continued similiar high levels of urinary m-methylhippuric acid up to the animals pretreated 12 times and then those treated 16 times defined the significantly decreased urinary m-methylhippuric acid compared to those treated 12 times. On the other hand, hepatic aniline hydroxylase and alcohol dehydrogenase activities demonstrated a gradual increase from the first group to the 12 times xylene-treated animals, but those treated 16 times showed the significantly decreased value compared with the 12 times treated-group. And aldehyde dehydrogenase activities in rats treated with m-xylene 8, 12 or 16 times were significantly decreased compared to those pretreated one or four times. In the early stage of xylene administration, proliferation of SERs were seen whereas SERs were decreased and RERs were clearly increased in xylene-treated rats 16 times. These results indicate that the frequency of xylene injection may influence upon the changes in xylene metabolite, m-methylhippuric acid and it may be due to induction of xylene metabolizing enzymes.

농업협동조합중앙회 지배구조의 문제점

전형수,박태원 대구대학교 경제경영연구소 2007 경제경영연구 Vol.5 No.1

지난 2004년 12월 농업협동조합(농협)중앙회의 지배구조에 대한 개정안이 국회를 통과하였다. 이로 인하여 농협의 지배구조에 적잖은 문제점들이 제기되었다. 예를 들면, 농협중앙회의 소유와 경영 분리문제는 협동조합의 관점에서 본 것이 아니라 이윤배당을 중시하는 주식회사의 관점에서 본 것이기 때문에 협동조합의 특성을 제대로 파악한 것이라 볼 수 없다. 또한 총회의 관한을 약화시키고 상임이사의 권한을 강화한 점 또한 협동조합의 특성을 유지&#8228;발전하기 보다는 협동조합의 정체성을 훼손하는 결과를 초래하였다. 이처럼 농협의 특성과 지배구조는 일반자본기업(주식회사)의 특성과 지배구조와는 엄연히 다를 수밖에 없다. 이에 본 논문은 협동조합의 특성과 원칙, 아이디어를 전제조건으로 농협중앙회 지배구조의 문제점을 지적 하려한다. The amendment of regulations affecting the governing body of National Agricultural Cooperative Federation (NACF) has been know to the public in December 2004. This brought many issues to governing structure of NACF. For example, the issue of the separation of ownership and management of NAFC was raised not from the perspective of cooperatives but from the company emphasizing the profit dividend. Therefore, it misses the features of cooperatives. Additionally it weakened the authority of the general meetings and enforces the authority of the directors, which brought damage to the identity of cooperatives rather than maintain or improve it. As such the characteristics and the governing structure of cooperatives cannot help being different from those of general companies (limited liability companies). Thus, this article will point the problems of corporate governance of NAFC under the characteristics, principles and ideas of cooperatives.

액정유체의 압력 유도 흐름에서의 분자 배향과 속도 분포

한원희,조정호,전종기,노상균,고승태 동양대학교 2001 동양대학교 논문집 Vol.7 No.1

본 연구에서는 액정의 압력 유도 흐름에 대해 적응성 토크 균형식과 코시 운동량보존식을 액정 연속체 이론의 핵심이 되는 Leslie-Ericksen 이론에 적용하여 수치해석 방법들로 풀어내었다.비선형 편미분 방정식계의 해를 구할 때 경계조건으로 쓰인 분자 배향닻 조건은 평행 닻조건(parallel anchoring)과 직교 닻조건(homeotropic anchoring)이다.분자 배향 분포는 평행 닻조건에서나 직교 닻조건에서나 시간이 지남에 따라 간단한 전단 흐름에서와 같이 3차원 비평판 배향의 구조를 갖게되지만 배향 비틀림의 구조가 다름을 알 수 있었다.배향 비틀링의 3차원적 구조를 갖게됨에 따라 압력 구배가 걸리는 흐름방향의 주 속도 분포뿐만 아니라 직교되는 방향으로 부 속도분포가 생기며 정상상태로 발전해가는 속도 분포 진화는 점근적이 아닌 진동적이다.비정상상태에서나 정상상태에서 속도 분포는 비 뉴톤성임을 알 수 있다.비등방성 Miesowicz 점도 순열에 따른 평행 닻조건에서의 더 많은 흐름량을 볼수 있고 직교 닻조건에서는 벽면에서 보이는 작은 속도 구배량의 특징을 가진다.
