  • Immediately after liberation, Shin Kwang-ryul served as the director of the Shinbukcheong People's General Hospital, and defected to South Korea alone in December 1945 with hostility to the Soviet military government. Later, he joined the political operation team (政治工作隊) and was dispatched to the Sinbuk Office as a member of Hamgyeong-do's committee. However, after this was revealed, his wife was taken to the security and tortured to death. Later, when he learned about this, he left a Wolnam Yuseo (越南遺書) and decided to commit suicide. He left politics and started a new family while running a pharmacy. In 1950, he fled Dangjin, Chungnam, during the Korean War and opened an East Asian medical clinic. In 1955, he passed the Korean Medical Examination and opened Cheongpa Oriental Medicine Clinic in Asan, Chungcheongnam-do. In 1969, he ran an East Asian medical clinic in Dohwa-dong, Mapo, Seoul, and moved to Hongeun-dong in 1972 to open Hamnam Oriental Clinic. At this time he wrote a Cheongpa Pharmacy Summary (靑坡驗方要訣). In his later years, he treated poor patients for free, and he continued to work even though he was unwell due to a broken spine. He died in 1980 leaving behind a "proud mind".

  • Side scan sonar using acoustic wave plays a very important role in the underwater, sea floor, and shallow marine geologic survey. In this study, we have acquired side scan sonar data for the underwater man-made structures, artificial reefs and fishing grounds, installed and distributed in the survey area. We applied digital image processing techniques to side scan sonar data in order to improve and enhance an image quality. We carried out digital image processing with various kinds of filtering in spatial domain and frequency domain. We tested filtering parameters such as kernel size, differential operator, and statistical value. We could easily estimate the conditions, distribution and environment of artificial structures through the interpretation of side scan sonar.

  • This paper presents a control algorithm for a large salient-pole synchronous motor fed by a Load Commutated Inverter (LCI). Many papers have been presented in the past few years on the justification, design, and application of variable-speed drive. The focus of this paper is on high torque operation and the estimation of initial rotor position. The results of simulation indicate that it is possible to produce the maximum torque and estimate the initial rotor position.

  • The metallic interconnector has a superior property than the ceramic interconnector in the point of the cell performance, but has problems to form oxide films on the interconnector surface during cell operation and induce cracking in the cell due to the stress by the thermal expansion coefficient difference with stabilized Zr electrolyte. For solving the problems in the metallic interconnector, new and modified materials have been investigated. In this paper, $LaCrO_3$ dispersed Cr was evaluated in high temperature oxidized characteristics, sintering density, electrical conductivity and various thermochemical properties. The test results show that $LaCrO_3$ dispersed Cr has more superior properties than that of conventional alloy interconnector and $LaCrO_3$ dispersed Cr can be used as an interconnector in SOFC.

  • According to the rapid growth of high speed and precise industry the application of synchronous motor has been increased. In the application fields, the fast dynamic response is of prime importance. In particular, since the PMSM has characteristics of high speed, high thrust, it has used in high-performance servo drive. From these reasons, it is recently used for high precise position control, and machine tool. In this paper, using the state observer, robust vector position control method for the purpose of improving the system performance deterioration caused by parameter variations is proposed.

  • The anode may inevitably undergo a number of reduction.oxidation (redox) cycles during solid oxide fuel cells (SOFCs) operation. The re-oxidation of Ni to NiO causes significant mechanical stress to be developed across the anode, which may destroy the integrity of the whole cell. In this study, the redox behavior of Ni-YSZ composite was examined at $800^{\circ}C$ using various characterization techniques.

  • We investigated the temperature uniformity in an anode-supported solid oxide fuel cell, using the open source computational fluid dynamics (CFD) toolbox, OpenFOAM. Numerical simulation was performed in three different flow paths, i.e., co-flow, counter-flow, and cross-flow paths. Gas flow in a porous electrode was calculated using effective diffusivity while considering the effect of interconnect rib. A lumped internal resistance model derived from a semi-empirical correlation was implemented for the calculation of electrochemical reaction. The result showed that the counter-flow path displayed the most uniform temperature distribution.
