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.

To study the influence of phase change of solution and fluid flow on low temperature in thermal storage, solar pond and removal of oil pollution at the sea, an experimental study was carried out in the square cavity filled with stratified fluids of silicone oil and aqueous sodium chloride. In the case of the lower cooling surface, the temperature of the system was dominated by conduction owing to the temperature and concentration fields stabilized by gravity. Liquid superheat influenced less in the lower part and the maximum density of sodium chloride became lower as the salt concentration got higher in the upper part. And the lower the initial temperature in the system the lower the temperature distributions were. When the actual liquid temperature was lower than the liquidus temperature with Ci = 15%, a supercooling phenomenon was observed But with Ci = 5% and Ci = 10% the actual liquid temperature was higher than the liquidus temperature and the temperature of upper fluid also got lower when the concentration of sodium chloride became lower. The influence of latent heat was less in the lower part and the raising ratio in temperature was higher when the initial concentration was lower in the upper part.

Since 1984, many cultures of Leptospira interrogans have been isolated from patients and wild rodents. The majority of isolates were identified as serogroup Icterohemorrhagiae serovar lai and two isolates(HS7, HK14) were identified as serogroup Canicola serovar canicola. Yet some isolates(18R, 30R, HM3, AP33, CH88-19, HK12) did not belong to any known serovar in Icterohemorragiae. Therefore, we tried to cross-agglutinin absorption test(CATT) to identify the serovar of above seven local strains with reference strains. We also tried to analyze the distribution of major antigenic determinants among reference strains and local strains in Korea with absorbed sera, by means of monoclonal antibodies and factor analysis. Local strains, AP33 could be identified serovar lai by CATT and using monoclonal antibodies. We proved that AP33 shared the major common antigen with serovar lai by factor analysis. Local strain, 30R and HM3 were proved same strain using CATT, monoclonal antibodies, and factor analysis. Local strain, 18R, 30R, HM3, CH88-12, and CH88-19 were antigenically different from reference strains.

This study examines the children’s basic preference of character shown in the process of recognition and judgment through self-report of the response recognized by themselves, forecasts its individual and complex results and then aims at developing more creative and effective sports programs to guide and train the athletes. For this, the data from 510 elementary school students in Kwangju and Chonnam regions. (310 athletes and 200 non-athletes) are analyzed and then the following conclusions are obtained, 1) As a result of comparing the character features of athlete group and non-athlete group, the athletes group shows higher proportion in extroversion, intuition and judgment type than non-athletes group and there is little difference in thinking type between two groups. Also both groups prefer ENFP and ESFP most. 2) According to the test of creative thinking difference by four character preferences of athletes in elementary schools, there are statistically significant differences in fluency and originality based on E-I index and perceptual openness and flexibility based on S-N index. In addition, there are significant differences in perceptual openness and fluency based on T-F index and the some of creative thinking. P preference group showse significantly significant differences only in the factor of perceptual openness based on J-P index and there is no significant difference in fluency, flexibility and originality.

Searching for cholinesterase inhibitory compounds from natural products is important to de- velop therapeutic agents for Alzheimer’s disease. Our previous research on the chemical components of Sophora flavescens roots resulted in the isolation of twelve flavonoids, kushenol E (1), maackiain (2), 8-prenylkaemperol (3), 8-prenylnaringenin (4), kushenol L (5), kushenol A (6), kushenol C (7), kushenol B (8), sophoraflavanone G (9), kushenol H (10), isoxanthohumol (11) and kurarinone (12) and their structures were elucidated by spectroscopic methods. Inhibitory effect of cholinesterase were tested using the Ellman's method. Most flavonoid compounds showed good inhibitory activities on cholinesterases. Kushenol E (1) and sophoraflavanone G (9) showed good inhibitory activities on acetylcholinesterase with IC50 values of 3.75 and 4.14 μM and butyrylcholinesterase with IC50 values of 2.00 and 0.75 μM, respectively. In addition, a kinetic analysis revealed that kushenol E (1) was non-competitive inhibitor with Ki value of 0.77 μM on acetylcholinesterase and 0.16 μM on butyrylcholinesterase, whereas sophoraflavanone G (9) was mixed type inhibitior with Ki value of 9.42 μM on acetylcholinesterase and 0.81 μM on butyrylcholinesterase. These findings suggest that flavonoid compounds from S. flavescens roots are potential cholinesterase inhibitors.

The drug metabolism of several antituberculosis was investigated in liver injuried rabbits. Antituberculosis drugs which used on this experiment were Rifampicin, Isoniazide and Pyrazinamide. The results were as follows. 1. Activities of sGOT and sGPT of rabbits induced liver injury by CCl_4 were increased (in sGOT, from 48.9 ± 1.48 units/ml to 370 ± 19 units/ml and in sGPT, from 42.5 ± 1.22 units/ml to 386 ± 32 units/ml) after the lapse of 24 hours from CCl_4 administration and then they were decreased gradually with the lapse of time (in sGOT, to 310 ± 25 units/ml and in sGPT, to 285 ± 26 units/ml after the lapse of 72 hours from CCl_4 administration). 2. The rifampicin which cxcreted mainly through bile at a small dose administration was excreted in urine at a large dose administration. 3. Each antituberculosis drugs which administrated on this experiment was excreted more quantity in urine of CCl_4 pretreated rabbits as compared with normal rabbits. particularly, Rifampicin was excreted far more quantity in urine of CCl_4 pretreated rabbits all the time. 4. From the above results, it was recognized that many notice about use of Antituberculosis drugs to liver injuried body must be required.
