영한기계번역에서 영문의 복합문중 종속부사절이 한국어로 생성될 때, 종속절의 주절에 대한 의미에 따라 다양한 한국어 연결어미를 생성하게 된다. 주절의 의미를 보완하는 종속절은 그 연결어미에 의해 그 역할이 결정되는 것이다. 종속부사절을 이끄는 부사어는 연결어미로 재현되는데 기존의 사전을 기반으로 하는 기계번역시스템에서 사전에 있는 부사어의 표층어만을 이용하였기 때문에 그 생성결과가 만족스럽지 않았다. 영문의 부사어중의 일부는 한국어로 생성될 때 의미적 구분에 따라 여러 가지의 연결어미로 생성이 되어야 하는데 영어 해석에서 종속절의 의미 정보를 충분히 분석하지 못하는 경우가 많다. 본 연구에서는 종속부사절을 이끄는 영어의 부사어와 각 부사어가 생성될 때 필요한 한국어 연결어미를 정리하였다. 또한, 형태소와 구문 자질정보를 이용하여 여러 연결어미를 갖는 부사어의 경우에 하나의 연결어미를 선택한다.

Good health and longevity is the goal of huamn beings. Recently, 'Dietary treatment' has become influential as one of the means for it in western medicine. Whereas in oriental medicine, 'Dietary treatment' was not recognized as therapeutic method but care of health. in this paper, the viewpoints of 'Dietary treatment' in oriental and western medicine was compared and searched for new possibilities in oriental medicine. And the results were as follows. 1. In oriental and western medicine, food was obviously recognized as a source of nourishment, and moreover oriental medicine took even a human soul into consideration. 2. Western medicine made much of nourishment and was analytical and therapeutic-centered. on the other hand, oriental medicine took a serious view of prevention and care of health. 3. Oriental medicine considered that intake of food was a adoption of Gi(氣) and then it helped a circulation of Gi and beneficial for the production of Jeong(精). 4. The principles of diet in oriental medicine was reasonable combination of food, balance of Oh-Mi(五味), temperance of food and intake by physical constitution.

Optical properties of $Cd_{1-x}Zn_{x}S$ films deposited by :chemical bath deposition(CBD), which is a very attractive method for low-cost and large-area solar cells, are presented, Especially, in order to control more effectively the zinc component of the films, zinc acetate, which used as the zinc source, mixed in reaction solution after preheating and the pH of the reaction solution decreased with increasing the concentration of zinc acetate. The films prepared after preheating and pH control had larger zinc component and higher optical band gap. As the more zinc substituted for Cd in the films, the optical transmittance improved, while the absorption edge shifts to a shorter wavelength and the optical band gap increased. The photo conductivity of the films was larger than the dark conductivity, while the ratio of those increased with increasing the mole ratio of zinc acetate.

The behavior of combustion-induced internal flow of SRM equipped with fin-slot grain and submerged nozzle is very complex and diverse. Cold air-flow test for 2D and 3D scale models of SRM has been done in order to specify the visualization method to analyze particular internal flow patterns such as roll-torque inducing flow. Swirl flow induced by asymmetric vortical tube also has been visualized through employing various light source and recording directions.

The purpose of this study is assessing the characteristics of surface aging and recovery of hydrophobicity for silicone rubber which takes a great interest as outdoor insulation recently subjected to the combined stressed of salt fog and AC power. The methods for assessing are contact angle ATR-FRIR, AFM and XRD. In addition salt fog method is adopted as the artificial contamination experiment and AC power is applied 24 hour on and 24 hour off repeatedly for 5 cycles. The results suggest that degraded surface was more rough than virgin but was restored water repellency through the off cycle. It was due to not only the formation of fractal surface but also maintenance of hydrophobic surface by diffusion of low molecular oil. Although surface recovers initial hydropohbicity there are possibilities of decreasing electrical performance due to irreversable changes such as depolymerization of surface and loss of filler particles. This fact is confirmed by surface conductivity measurement showing that the degradation is significant and the recovery of hydrophobicity is imperfect as the energized cycle increases.

The maintenance of legacy software systems is very important in the field of a software engineering. In the maintenance, a regression test confirms the behavior preserving of the software which has been changed but most of regression tests are done in a system level and rarely done in a unit test level because there is no test case. This paper proposes how to modify legacy software systems and make unit test cases as an asset. It uses a technique with a specific module of a real software development project and analyzes test coverage results. After this, if a study about automatic restructuring techniques and a test case generation proceeds continuously, we can expect the big advance of legacy software systems maintenance.

A new concept of salt core, a melting temperature of which is lower than the solidus temperature of cast alloy, was introduced to produced an integrated casting part having a complicated inner shape or requiring under-cut in high pressure die casting or squeeze casting process. The main goal of this study is to develop a new integrated net-shape forming technology using fusible core of lower melting temperature than that of a casting alloy. This integrated net-shape forming technology would be very successful and cost-effective for producing the integrated products having a complicated inner shape or requiring under-cut. The technology for measuring and evaluating a various property of fusible core such as a thermal conductivity and thermal expansion coefficient, melting temperature was established. Also, the work space can be cleaned without a pollution inducing products.

Pt thin film of about 7000$\AA$ thickness was deposited on the alumina substrate using DC Magnetron Sputter and the characteristics of the film for temperature sensor were investigated. When film of about 7000$\AA$ thickness was deposited at working gas pressure of $2.0{\times}10^{-3}$torr, sputtering power of 50W, substrate temperature of $350^{\circ}C$(Ts), sheet resistance(Rs), resistivity($\rho$) and temperature coefficient of resistivity(TCR) of the film were respectively 0.39$\Omega$/$\square$, 27.60$\mu\Omega$-cm and $3350 ppm/^{\circ}C$. When the film was annealed at $1000^{\circ}C$ for 240min in hydrogen ambient, Rs, $\rho$ and TCR were respectively 0.236$\Omega$/$\square$, 15.18$\mu\Omega$-cm and 3716 ppm/$3716 ppm/^{\circ}C$. When working gas of 15sccm oxygen and 100sccm Argon were used, Rs, $\rho$ and TCR were respectively 0.335$\Omega$/$\square$, 22.45$\mu\Omega$-cm and $3427 ppm/^{\circ}C$. When the film was annealed at $1000^{\circ}C$ for 240min, Rs, $\rho$and TCR were respectively 0.224/$\Omega$$\square$, 14$\mu\Omega$-cm and $3760 ppm/^{\circ}C$ and the characteristics of the film were much improved.

The flowfield in a solid rocket motor was simulated at the wall-injection test model, which has a fin-slot grain and submerged nozzle, and visualized by a smoke-wire. The high speed CCD camera captured the visualized images around the nozzle inlet through the grain center port. The vortical tube structure and circumferential flow patterns at the nozzle throat were visualized. The radial momentum transfer caused by the shear-interactions of slot-outlet flow, fin-base flow and grain port flow from upstream worked as the source of these phenomena.
