In this paper, a compliant buoy mooring system of a floating cylindrical structure in shallow water depth is studied experimentally. The compliant buoy mooring system consists of four buoys, vertical mooring legs and horizontal mooring lines. A series of model test were carried out at KRISO ocean engineering basin for various mooring parameters; line length, pretension of mooring leg and mooring layouts and environmental conditions; regular and irregular waves combined with current and wind. The mooring line tensions and 6-DOF motions of the floating structure were measured using water-proof load cells and 3 CCD camera system. The results of a series of model tests were discussed on nonlinear motion behaviors of the floating structure and characterisitics of cumulative distributions of mooring line peak tensions.

On-line screening high performance liquid chromatography (HPLC)-$ABTS^+$ assay를 이용한 청호로부터 chlorogenic acid, caffeic acid, vitexin, queretin, aremisinin의 항산화 활성을 온라인스크리닝 하였다. 이때 침적방법을 적용한 추출시간과 추출용매 조성으로부터 추출효율을 확인하였다. 이 결과 100% 물 추출물에서 수율이 가장 좋왔고 chloroenic acid의 항산화 활성이 가장 높았다. 또한 on-line screening HPLC-$ABTS^+$ assay 분석은 천연물에서 항산화 활성을 신속하게 탐색하는데 효율적이다.

본 연구의 목적은 어류 옆줄(측선)이 수온, 수압, 수류 및 음파 등을 측정한다고 알려진 것을 직접 실험을 통해 확인하여, 어류 옆줄의 물리적 자극을 감지함을 확인하였다. 어류 옆줄 감각기능 실험연구 후 어류 옆줄이 물리적 자극을 감지하는 우수성을 확인하기 위해 옆줄 조직을 확대 분석하였으며, 측공과 측공관의 형태를 3D프린터로 제작하여 옆줄 교구 제작을 실현하였다. 옆줄 교구를 수중에서 물리적 자극인 음파를 측정함으로써 증폭 효과를 확인하였고, 이를 통해 어류 옆줄이 생명공학적으로 우수한 감각기관임을 증명하였다.

Purpose: The purpose of this study was to examine the effects of Self-Development training on the Human Relationship and Intrinsic Motivation for first-line nurse managers. Method: This was an empirical study on the Human Relationship and Intrinsic Motivation of Self Development Training. The researcher developed a new Self-Development Training Program, and the two-hour long training session was performed twice a week for each group. The program was performed for 4 session in two weeks. The subjects consisted with 24 nurse managers from C University Hospital in Seoul, Korea. The subjects were divided into two groups for the training. Two weeks before and 4 weeks after the training, subjects completed questionnaires that measured Human Relationship and Intrinsic Motivation. Analysis was completed by using SPSS PC 10.0 for percentile, mean, standard deviation and paired t-test. Result: The results of this study showed that Self-Development Training Program resulted in a significant effects on the Human Relationship. But the Intrinsic Motivation was not significantly affected by the program. Conclusion: This Self-Development training program had a positive effect on the Human Relationship and Intrinsic Motivation.

The station area development planed to improve the old and narrowed station and to enhance the train passenger's convenience through private capital attraction in the past. But it has been faced with difficulty for the creative of transfer demand. Because of lean upon building facilities were caused by shortage of business profitability as to development of the upside a railway line, and lack of public utilities. The station area development requires that it's trend to large scale development of station areas, korail's direct development, deputation of specialty company to development, collaboration between local government and korail in development, diversification of process & installed facility, building multi-transfer center and one-stop transfer system. This trend caused by low profitability in development of the upside a railway line. The purposes of study are to make the system and law reflected to the property of station area development, investment in kind of needed land, and change railroad areas to high-rise and complex development, and make a forum between government and korail, etc.

The generator on-line diagnosis system has been developed. This system monitor the insulation condition of stator winding by on-line measurements of partial discharge and the shorted-turn condition of rotor winding by on-line measurements of slot leakage flux. Sensor, such as SSC(Stator Slot Coupler) and flux probe are used for generator on-line diagnosis.

In this paper, we designed and fabricated a fast switching system for high power pulse. This system consists of a voltage conversion circuit, high voltage charging circuit, trigger circuit, and discharging circuit. Especially discharging line is designed by strip-line for low inductance and resistance. The experimental result is that current slew rate of the system is 6.67kA/86ns and this result is fully qualified for initiating EBW or EFI

Three TNF-$\alpha$inhibitory lignans were isolated from the flower buds of Magnolia fargesii through bioassay-guided isolation. They were identified as eudesmin, magnolin and lirioresinol-B dimethylether on the basis of their spectroscopic data. All three lignans showed inhibitory effects on TNF-$\alpha$ production in LPS-stimulated murine macrophage cell line, RAW264.7 and eudesmin showed the strongest activity ($IC_{50}=51{\mu}M)$.

We applied the Atmospheric Pressure Plasma (AP-plasma) to the MgO film to try to control the Aging-time on the PDP production-line. The MgO film surface and the discharge characteristics of AC-PDPs were investigated, using the plasma-treated MgO film. The Aging-time change can be achieved by treating the MgO film with plasma. This method can be adapted to the mass production-line.
