The purpose of the study was to investigate how the Classification of the Joseon Dynasty's Beauty characteristics were expressed in a TV documentary focusing ona Re-mediation theory. The methods of study comprised of library research, Internet search, and using TV documentary program case studies. The work this Researcher makeup in the manufacture from the documentary in which the methods the Joseon. Dynasty expressed were selected. The literature, and preceding research, were referred to as a way to help organize the Joseon Dynasty's 'gi-saeng Hwang Jin-Hee', 'woman of royal family', and way of make-up of 'sadae-bu lady'. The TV documentary programs selected were 'MBC special' and '2 parts of channel A documentary special'. First, the improvisation of nature and simultaneity expressed in the Joseon Dynasty's usage of make-up is shown through the interview form reflecting the make-up tools and age direction of the scenes or expert. Second, the interactivity and reality are well seen through the row equivalent in which the model seems to directly use the dressing demonstration of the expert and cosmetics material. Third, the cultural expandability and unexpectedness show through the production of situations which are viewed from the explanation of the narration and letter subtitles and drama.

유도 결합 플라즈마 (ICP)는 축전 결합 플라즈마 (CCP) 보다 상대적으로 높은 밀도의 플라즈마를 발생시킬 수 있다. 또한 구조가 간단하고 기존 스퍼터링 장치의 내부에 추가 설치가 용이하며, 스퍼터된 입자의 이온화, 반응성 가스의 활성화를 위한 2차 플라즈마원으로 적용이 가능하다. 그러나 대면적의 고밀도 플라즈마의 균일도 측정은 고가의 2D probe array등을 사용하여야 한다. 본 연구에서는 간단한 CCD camera를 챔버 내부에 삽입하여 가시광 영역의 적분 강도를 이용해서 플라즈마의 2차원적 균일도를 정성적으로 비교 판단하고 시간에 따른 국부적인 이상 방전을 감시할 수 있도록 내장형 무선 카메라를 사용하였다. 직경 380 mm의 챔버 내에 2 turn ICP antenna를 이용하여 유도 결합 플라즈마를 발생시켰다(Ar 30 sccm, 35 mTorr, 2 MHz, 400 W). 내장형 무선 카메라를 챔버 내부 중앙의 ICP antenna에서 8 cm 아래에 위치시켜 플라즈마를 진공 중에서 촬영하였다. 내장형 무선 카메라를 챔버 내부에 위치하여 촬영한 결과 외부에서 view port로 쉽게 확인할 수 없는 ICP antenna 내부의 고밀도 플라즈마의 불균일도를 평가할 수 있었고, ICP antenna 가장자리에서 중심으로 이동할수록 밝아지는 것을 토대로 중심 영역의 plasma 밀도가 가장 높다는 것을 알 수 있었고, 채도와 명도의 차이를 이용하여 시각적인 플라즈마 균일도를 분석하였으며 이를 플라즈마 모델링 기능이 있는 전산 유체 역학 프로그램인 CFD ACE+를 이용하여 플라즈마 분포를 모델링 및 비교하였다. 또한 인라인 타입의 마그네트론 스퍼터링 시스템에서 기판 캐리어에 무선 카메라를 장착하여 이동하면서 캐리어와 마그네트론 방전 공간의 상대적인 위치에 따른 마그네트론 방전링의 형상 변화도 관찰하였다.

According to <> and <>, Taeum is strongly related to dampness, earth, and canter. The origin of Taeum is dampness and the presentation of it is dryness, thus spleen plays a greater role than lung in physiologic and pathologic aspect. Taeum meridian cooperates with Soeum and Guelum meridian, and spreads yin gi through spleen and lung meridian. Among six meridian types that are invented by Ji-San, Taeum type possesses lowered eyes and nose and displays characteristics of Taeum disease. Instead of five jang organs and six bu orqans, meridians are major factor of Taeum type. Thus SiDongByung (disease of gi) and SoSaengByung (disease of blood) are considered more significantly than internal and external symptoms of organs. Personality of Taeum type is realistic, pragmatic, diligent, and occasionally selfish. Medications for Taeum type are described as following. GwakHyangJungKi-San or InSamYangWi-Tang can be considered for the complication of intrinsic and extrinsic diseases, which are caused by yin symptom of SangHan. If cold stomach affected by Taeum disease causes an abdominal pain and diarrhea, YiJoong-Tang or PalMiYiJoong-Tang are suggested.

Many chapters of the Hwangjenaegyeong[HN] explain the process of transmission and transmutation of disease. The transmission and transmutation process in the HN can be categorized into one between the viscera and bowels, and another of the external pathogenic gi itself. The process between the viscera and bowels indicates the transport of the pathologic burden between each viscera and bowel. This again is categorized into three types. Interpromoting, intercontrolling and that by Saeng-yang(生陽), Sa-eum(死陰). Next, the transport of the pathogenic gi can be categorized into one moving inwards from the exterior according to personal traits, and that according to the three Eum and three Yang. Although there are numerous types of transmission and transmutation, there are two main criteria in understanding the process. First, whether the process is in accordance with the physiological or natural flow of the body. Interpromoting and three Eum three Yang processes are such examples. To follow the physiological flow of the body means to correspond to either the Heaven and Earth or the original physiology of the human body. Therefore, the disease progresses according to a certain date or season. This indicates a partial malfunction in the circulation of the vital energy, which is relatively easy to recover. In contrast, there are processes that go against the physiological flow, for example, intercontrolling transmission and transmutation. This process focuses on the movement of the pathogenic gi rather than the vital gi. The disease progresses regardless of the flow of the vital energy, and sequential functional damage occurs accordingly. Consequently, as the transmission and transmutation continue, formerly passed organs are left damaged, and the whole process is headed towards death. The second criteria for understanding the process is whether it is cyclic or not. To have a cyclic pattern means that the occurrence of a disease and the time of death is not fixed. Transmission and transmutation processes that have a cyclic pattern mostly follow the physiological flow of the body. As a result, they rarely end in deaths, and the process is centered on vital energy. On the other hand, those with acyclic patterns have a fixed occurrence and death point in the course of the disease. They are mostly unnatural processes, found in fatal acute diseases or consumption diseases.

The goal of this study is to investigate bending properties of domestic timber. Three representative structural timber from Larix kaempferi, Pinus koraiensis, and Pinus densiflora, in the northeastern South Korea were selected. Visual grading for the timber was conducted based on KFRI notification 2009-01 and the bending strength for the timber was evaluated based on ASTM D 198 bending. The high percentage of grade 1 and 2 for Larix kaempferi shows that the KFRI notification was optimized for this species. The bending strength distributions from Pinus koraiensis and Pinus densiflora were very similar. It could be possible to specify the allowable bending properties of these two Specification using a united species group similar to spruce-pine-fir. Lastly, the bending strength of $120{\times}180mm$ structural members was higher than both existing values in KBC 2009 and design values for timber of imported species described in the NDS. Thus, 120 mm thick domestic softwoods could replace the commercial imported species and the KBC should be modified to provide design values for both timber and dimensional lumber, respectively, like NDS.

Panax ginseng is one of the most important medicinal plants in Asia. Triterpene saponins, known as ginsenosides, are the major pharmacological compounds in P. ginseng. The present study was conducted to evaluate the changes in ginsenoside composition according to the foliation stage of P. ginseng cultured in a hydroponic system. Among the three tested growth stages (closed, intermediate, and opened), the highest amount of total ginsenoside in the main and fine roots was in the intermediate stage. In the leaves, the highest amount of total ginsenoside was in the opened stage. The total ginsenoside content of the ginseng leaf was markedly increased in the transition from the closed to intermediate stage, and increased more slowly from the intermediate to opened leaf stage, suggesting active biosynthesis of ginsenosides in the leaf. Conversely, the total ginsenoside content of the main and fine roots decreased from the intermediate to opened leaf stage. This suggests movement of ginsenosides during foliation from the root to the leaf, or vice versa. The difference in the composition of ginsenosides between the leaf and root in each stage of foliation suggests that the ginsenoside profile is affected by foliation stage, and this profile differs in each organ of the plant. These results suggest that protopanaxadiol- and protopanaxatriol(PPT)-type ginsenosides are produced according to growth stage to meet different needs in the growth and defense of ginseng. The higher content of PPT-type ginsenosides in leaves could be related to the positive correlation between light and PPT-type ginsenosides.

This experiment was carried out to investigate ultrastructural changes that occurred in bovine epididymal spermatozoa during incubation in a BO medium supplemented with 5 mM caffeine. No structural changes were observed under electron microscope in the majority of non-incubated sperm(79.8%) keeping the membrane intact. Structural changes were however observed when spermatozoa were cultured in a BO medium supplemented with 5 mM caffeine, which were classified into 4 types, intact(29.4%), vesiculated(45.6%), acrosome lost(17.8%) and degenerated(7.2%) spermatozoa, respectively. These results indicated that : 1) vesiculation of spermatozoa membrane is normal acrosome reaction and acrosome lost of spermatozoa is dead one ; 2) caffeine can induce acrosome reaction of bovine epididymal spermatozoa.

고휘도 고효율 백색 LED (lighting emitting diode)가 차세대 조명광원으로 급부상하고 있다. 백색 LED를 생산하기 위한 공정에서 MOCVD (유기금속화학증착)장비를 이용한 Epi wafer공정은 에피층과 기판의 격자상수 차이와 열팽창계수차이로 인하여 생성되는 에피결함의 제거를 위하여 기판과 GaN 박막층 사이에 완충작용을 해줄 수 있는 버퍼층 (Buffer layer)을 만들고 그 위에 InGaN/GaN MQW (Multi Quantum Well)공정을 하여 고휘도 고효율 백색 LED를 구현할 수 있다. 이 공정에서 기판의 온도가 불균일해지면 wafer 파장 균일도가 나빠지므로 백색 LED의 yield가 떨어진다. 균일한 기판 온도를 갖기 위한 조건으로 기판과 induction heater의 간격, 가스의 흐름, 기판의 회전, 유도가열코일의 디자인 등이 장비의 설계 요소이다. 코일에 교류전류를 흘려주면 이 코일 안 또는 근처에 있는 도전체에 와전류가 유도되어 가열되는 유도가열 방식은 가열 효율이 높아 경제적이고, 온도에 대한 신속한 응답성으로 인하여 열 손실을 줄일 수 있으며, 출력 온도 제어의 용이성 및 배출 가스 등의 오염 없다는 장점이 있다. 본 연구에서는 유도가열방식의 induction heater를 이용하여 회전에 의한 기판의 온도 균일도 측정을 하였다. 기초 실험으로 저항 가열 히터를 통하여 대류에 의한 온도 균일도를 평가하였다. 그 결과 gap이 3 mm일 때, 평균 온도 $166.5^{\circ}C$ 에서 불균일도 6.5 %를 얻었으며 이를 바탕으로 induction heater와 graphite susceptor의 간격이 3 mm일 때, 회전에 의한 온도 균일도를 측정을 하였다. 가열원은 induction heater (viewtong, VT-180C2)를 사용하였고, 가열된 graphite 표면의 온도를 2차원적으로 평가하기 위하여 적외선 열화상 카메라(Fluke, Ti-10)을 이용하여 온도를 측정하였다. 기판을 회전하면서 표면 온도의 평균과 표준 편차를 측정한 결과 2.5 RPM일 때 평균온도 $163^{\circ}C$ 에서 가장 좋은 5.5 %의 불균일도를 확인할 수 있었고, 이를 상용화 전산 유체 역학 코드인 CFD-ACE+의 모델링 결과와 비교 분석 하였다.

Abstract In this work. gasification of graphite cores from nickel-coated graphite composite powders was carried out to munufacture the hollow nickel metal powders which can be used as a raw materials for porous nickel metal strips. Graphite cores were gasified by $H_2O-H_2$ mixture gases at the temperature between $800^{\circ}C$ and $900^{\circ}C$ and nearly all removed from the composite powders within 1 hour. The hollow nickel metal powders prepared from 82.2wt. % Ni-17.8wt. % C composite powders which have the graphite cores of 21${\mu}$m average size were pressed and sintered at $1150^{\circ}C$ for 1 hour in vacuum furnace. The porosities of green and sintered compacts were 45% and 30%. respectively, and pores were distributed very homogeneously in the sintered compact. It was confirmed that pore distribution and porosity in porous materials can be easily controlled by using hollow powders as a raw materials.
