  • 초대형 플로팅 구조물의 상부구조는 육상 구조물과는 달리 파랑하중의 영향을 받기 때문에 하부부체의 변형에 의해서 상부구조물에는 부가 모멘트가 크게 발생한다. 이와 같은 부가모멘트의 저감을 위하여 보-기둥 접합부에 반강접의 도입에 관한 연구와 반강접의 비선형 거동을 고려한 상부구조물의 연구는 초기단계이다. 본 연구에서는 초대형 플로팅 구조물의 상부구조물에 정적하중과 진폭의 크기가 다른 파랑하중이 동시에 작용할 경우 강접 골조와 부분적으로 반강접 접합부가 사용된 상부구조체에 대한 1, 2차 소성해석을 수행하였다. 접합부는 웨브에 더블 앵글을 가진 상하 앵글(TSD)접합을 적용하였으며 상부 구조물에 파랑하중이 작용할 경우 소성거동에 따른 응답특성에 대하여 분석하였다.

  • Rice straw liquid was prepared from rice straw using simple pyrolysis furnace, and its effects on plant growth and antibiosis were investigated. Effects of straw liquid on plant growth of Oryza sativa L., Glycine max Merr. and Lactuca sativa L. and antibiosis of bacteria and mold of rice straw liquid were studied. Th rice straw liquid showed good results on plant growth and multiplication. Rice straw liquid showed a little antibiosis on bacteria but non antibiosis on mold. Rice straw liquid had minimal inhibitory concentration of 2.5-5% for bacteria.

  • Monitoring system is essential part in control system to monitor the circumstances of the industrial equipments. Color graphics is generally introduced in the monitoring system for the purpose of effective human interfaces. Hence, color graphic editor is under the implementation to draw graphic elements easily which are utilized in the monitoring situation. In this study, OOP(object oriented programming) is applied in the programming of the software. OOP enables systematic design of algorithm, easy management of the software and easy extension of additional functions. It is reported that the software is under the implementation. Therefore, preliminary structure of the software is briefly discussed in this paper.

  • DW -224a is a fluoroquinolone antibiotics with a broad spectrum of activity against Gram-positive and Gram-negative bacteria. In order to clarify toxicokinetic profile of DW-224a, a 4-week repeated dose oral toxicokinetic study (dose level: 0, 63, 250, 1000 mg/kg) was conducted in groups of Sprague-Dawley rats.(omitted)

  • An integrated type fire alarm control panel which is for the purpose of the ubiquitous environment application is reported. For the ubiquitous environments, mainly three additional functions upon its inherent capabilities are implemented. That is, wireless technology with ZigBee capability is applied for the interface of ZigBee detectors. Camera images can be displayed in the fire alarm control panel in which images are transferred via ethernet. For the time synchronization of the distributed fire alarm control panel, GPS module is introduced and implemented in the system.

  • A variety of geophysical well loggings have been conducted to investigate the geological characteristics for basaltic volcanic area in Jeju Island. Specially, there is no precedent case study using geophysical well loggings in Jeju Island. And so, the proper understandings for geological features of Jeju Island are the key to interpret geophysical well logs. Presently, seawater intrusion monitoring systems have been constructed for systematic development and conservation of groundwater resources. As the results of geophysical well loggings in this seawater intrusion monitoring boreholes, the responses of well logs for saturated zone have distinctly identified basalt sequences. In particular, neutron logging, gamma-gamma (density) logging, and resistivity logging have well exhibited the characteristics of lava flows and lithologic boundaries. In hyalocastite, porosity is high, and resistivity is low. Eventually, geophysical well logs are useful for securing sustainable development of groundwater in Jeju Island in that it has identified the characteristics of geological responses.

  • In this study, we have investigated the photoinduced birefringence(PB), ${\Delta}n$ in chalcogenide $As_{40}Ge_{10}Se_{15}S_{35}$ thin film with a He-Ne Laser at 633nm as In this study, we have investigated the photoinduced birefringence(PB), ${\Delta}n$ in chalcogenide $As_{40}Ge_{10}Se_{15}S_{35}$ thin film with a He-Ne Laser at 633nm as a pumping beam and a semiconductor laser at 780nm as a probing beam. The PB for the variable thickness of thin films was investigated. The thickness of the thin films is about $0.4{\mu}m$, $0.92{\mu}m$, $1.4{\mu}m$, $2.0{\mu}m$, respectively. The experimental result of PB in chalcogenide thin films was represented higher PB in the thickness of thin film, $0.92{\mu}m$. It was meant to represent higher PB in the thickness of the film that was made closely the optimal thickness, $0.96{\mu}m$. The optimal thickness of thin film, $0.96{\mu}m$ was calculated by the penetration depth of the pumping light Also, the PB in thickness of $0.92{\mu}m$ was obtained almost two times higher 0.15 than other thickness of thin films.

  • The incidence of liver cancer is markedly sex-differentiated epidemiologically, with a much higher frequency in men than in women. In experimental animals, male have higher incidence of liver tumors than female in carcinogen-induced tumors as well as spontaneous ones. Our studies were investigated to examine the modifying effects of sex hormones in the proneoplastic lesions of liver on diethylnitrosamine (DEN) - induced hepatocarcinogenesis. (omitted)
