We have successfully developed the KASI (Korea Astronomy and Space Science Institute) Solar Imaging Spectrograph (KSIS), which has been originally upgraded from the KASI solar spectrograph that was able to record solar spectra for a given slit region and to inspect the response function of narrow band filters. A prototype KSIS was developed in 2004 by using a scanning mirror in front of the spectrograph slit and a SBIG ST-8XE CCD camera. Its main disadvantage is that it took a long time (about 13 minutes) to scan a whole active region. In this work, we have upgraded the KSIS by installing a much faster Dalsa 1M15 CCD camera, which gives a data acquisition time of about 2.5 minutes. The software for KSIS was also improved for the new CCD camera on the basis of component-based development method. We have successfully made a test observation for a simple and small active region (AR10910) using the improved KSIS system. Our observations show that H-alpha images for several wavelengths have typical features in a sunspot as well as a H-alpha centerline image is quite similar to a BBSO H-alpha image, demonstrating the capability of the KSIS system.

도산 안창호는 1932년 4월 29일 윤봉길 의거 당일 상해에서 피체 되어 국내에 압송된 이래 1938년 3월 10일 숨을 거둘 때까지 6년 가까운 기간을 국내에서 보냈다. 그런데 신민회운동기나 미주활동기, 상해시기와 달리 그의 말년에 대한 기록은 단편적인 일화로만 전해질 뿐이다. 물론 투옥과 일제의 감시 속에서 뚜렷한 활동을 벌일 수 없었지만, 도산의 말년은 60평생의 파란만장한 역정을 되짚어 보고 민족운동 에 대한 자신의 마지막 구상을 가다듬는 시기였다. 또한 지역감정과 같이 도산의 활동을 둘러싸고 제기된 해묵은 문제들이 다시금 부각된 시기이기도 하였다. 이에 여기서는 도산 말년의 국내 행적과 관련된 단편적 자료들을 하나로 정리하는 가운데, 민족운동에 대한 그의 마지막 구상이 무엇이었는지, 어떠한 문제들을 놓고 힘겨운 씨름을 하였는지에 대해 살펴보고자 한다.

The effect of parameters on the consequence of the flash fire accident by the release of heavy gas(in this study, xylene vapor) was analyzed. Simulation results showed that the distance with the lower flammable limit(XLFL) was increased with the increase of the release hole diameter. For the case of the elevated release, XLFL was increased with the increase of the wind speed and the release height, but XLFL was not affected by the wind speed for the release on the ground level. Therefore, the accident in the elevated release was more dangerous than the release on the ground level. In this condition, the release height had more effect on XLFL at the night time than the daytime and in the urban area than the rural area.

본 연구에서는 안경과 콘택트렌즈를 착용한 근시 군을 NPA방법 (Near Point of Accommodation) 과 Minus lens 기법을 사용하여 조절력 측정의 신뢰성에 대하여 연 구하였다. 안경과 콘택트렌즈 착용군 사이의 상관관계는 NPA의 경우 44%(R = 0.44, P 二O.어452) 로 나타났고， Minus lens 기 법 의 경 우 85%(R = 0.85, P < 0.0001) 로 나타났다. 또한 굴 절이상도가 증가할수록 상관관계가 증가한 것으로 나타났다. 이것은 근시안에서 안경과 비교하여 콘택트렌즈 착용이 프리즘 영향을 받지 않아 폭주 부담을 많이 갖고 있기 때문으로 생각된다. 따라서 Minus lens 검사법이 안경 과 콘택트렌즈 착용자간의 조절력 측정 오차를 줄일 수 있는 정확한 검사법이라 사 료된다.

Ozone has become a significant pollutant not only outdoors but also indoors. The ozone emission test was conducted for the sum of forty five air cleaners selected in the online shops and department stores. Negative ion emission test was also conducted for the selected fifteen ones which had the function to generate negative ions. Filter-type and complex type air cleaners emitted ozone less than 0.05 ppm, the standard of indoor ozone emission of air cleaner. Wet type ones emitted no ozone. In the case of ionizer type, 66.7% in the nine ones emitted ozone about 1.4~10 times larger than 0.05ppm. Most of air cleaners used a pin corona discharge emitted large amount of ozone. Those which used carbon fiber emitted little ozone in spite of generating a lot of negative ions.

생육시기별 멜론의 비순환식 수경재배 폐양액은 NO3-N와 Ca 및 K 함량 등 양이온 함량이 높았고, 반대로 음이온은 약간 감소하는 경향을 보였다. pH는 5.7~7.0 사이를 유지하였고, EC는 멜론은 2.0~2.2 dS·m-1 사이를 유지하였다. 폐양액을 이용한 관비재배에서 멜론 식물의 초장, 근장, 그리고 엽록소 함량이 관비재배에서 증가하였다. 또한 과중도 417.1g 더 무거웠으며 과실의 ˚Brix당도는 관비재배가 13.3˚Brix로 1.4˚Brix더 높았다. 오이에서는 오이식물의 생육에는 차이를 보이지 않았으며 과실의 크기도 유의성 있는 차이는 없었으나 관비재배가 수경재배에 비하여 총수량과 상품과율에서 우수하였다.

2005년 4월부터 10월까지 횡성호를 중심으로 상 하부에 분포하는 참갈겨니(Zacco koreanus) 개체군의 동태를 알아보았다. 참갈겨니 개체군의 시기 별 변동을 비교한 결과 하부 지 역이 상부 지역보다 양호한 개체군을 유지하는 것으로 확인되었다 또한 참갈겨니 개체군의 전장-체중 상관도 분석 결과 하부 지 역의 b값은 3.21~3.35였고 상부 지역은 2.94~3.37로서 하부 지 역의 시기 별 개체군이 양호한 것으로 보였으며 상부 지 역은 빈약한 것으로 나타났다. 그리고 비만도지수(K)는 하부 지 역에서 0.0292~0.0693인 반면 상부 지역은-0.0165~0.0499로 하부 지 역에 비해 K값이 떨어지는 것으로 분석되었다. 한편 von Bertalanffy의 성장모델에 의해 산출된 본 개체군의 최대성장 값(L∞)은 상부 지역에서 279.7mm, 하부 지 역에서 303.9mm로 각각 나타나 하부 지역의 잠재성장능력이 상부 지역보다 높은 것으로 확인되었다. 이와 같이 횡성호 상부 지역의 참갈겨니 개체군은 연령구조, 전장-체중 상관도 분석, von Bertalanffy의 성장모델 결과에서 하부 지 역보다 떨어지는 것으로 나타났으며 이러한 결과는 댐의 형성으로 인한 수체와 물리적 서식환경의 변화 때문으로 보였다.

This study was carried out to evaluate the characteristics of volatile organic compounds (VOCs) and aldehydes emission as a function of airtight time in new apartment. Sampling was undertaken at 34 new apartments located in 4 different cities of Korea from February to November 2005. The measurement data were collected every one hour from 10 a.m. to 6 p.m. toward increasing airtight time in a day. The concentrations of VOCs and aldehydes were analysed by GC/MS and HPLC method, respectively. These methods showed good sensitivity, linearity, and repeatability. In this study, the most abundant compounds at new apartments appeared to be toluene, m,p-xylene, formaldehyde and acetone. Moreover, the concentration variations at a closed rooms progressively increased by airtight time of 5 hours. Airtight time of new apartment was a most important and affective factor which influenced concentration change.

This experiment was carried out to figure out the CO2 biomass and the growth response of Chinese cabbage and radish grown under the condition of high temperature and high CO2 concentration to provide the information for the coming climatic change. Chinese cabbage and radish were cultivated in spring and autumn seasons under 4 treatments, 'ambient temp.+ambient CO2 conc.', 'ambient temp.+elevated CO2 conc.', 'elevated temp.+ ambient CO2 conc.', and 'elevated temp. +elevated CO2 conc.'. The 'elevated temp,' plot was maintained at 5 higher than 'ambient temp. (outside temperature)'and the 'elevated CO2 cone.' plot was done in 650 ppm CO2. The growth of spring-sown Chinese cabbage was worse than autumn-sown one, and was affected more by high temperature than high CO2. concentration. The CO2 biomass of Chinese cabbage was lower as 25.1-39.1 g/plant in spring-sown one than 54.8-63.4 g/plant of autumn-sown one. Daily CO22 fixation ability was not significantly different between spring- and autumn-sown Chinese cabbage as 1.9-2.9, 2.7-3.1 kg/10a/day, respectively. The CO2 biomass of radish were 87.4-104.6 /plant in spring-sown one and 51.3~76.4 g/plant in autumn-sown one. Daily CO2 fixation ability of radish were 6.2-10.1 kg/10a/day in spring-sown one and 4.6-6.9 kg/10a/day in autumn-sown one.

The characteristics of odor and VOCs emitted from a sewage treatment plant was investigated to provide the basic informations in the design of odor and VOCs treatment processes. The sewage treatment plant which treated domestic wastewater only and consisted of a flow equalization tank, thicker, and sludge container was selected. Odor and VOCs sampled three times (June - July) at the temperatures ranging from 24℃ to 27℃ were analyzed by GC/MS and GC/FPD. Odors were hydrogen sulfide, dimethylsulfide, ammonia, and styrene. Among them, the main compounds were dimethyldisulfide (14.45~2,340.91 O.U.) and ammonia (18.51~16,520 O.U.). The order of odor dilution ratio and odor unit can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker. The main VOC produced from sewage treatment plant was benzenes, and the others were dichloromethane, toluene, ethylbenzene, m,p-xylene, styrene, 1,2,4,-trimethylbenzene, 1,3-dichlorobenzene, and 1,2-dichlorobenzene. The concentration of toluene of a flow equalization tank, thicker, and sludge container were produced from 70.38 ppb to 103.07 ppb, from 28.18 ppb to 40.35 ppb, and from 67.92 ppb to 180.26 ppb. The producing order of VOC can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker.

An analytical method for trimethylamine in ambient air was developed, using headspace gas chromatography with flame ionization detection. Trimethylamine was collected on the acid filter which was impregnated sulfuric aicd in the 47 ㎜ diameter of glass fiber filter. Trimethylamine collected on the acid filter was regenerated in the headspace vial and introduced into the GC analytical column directly. Several parameters such as sample volume, equilibrium temperature and time, and slurry method of filter were optimized to provide maximum detection response. Resolution power also compared according to liquid phase of analytical column. The detection limit of method was 0.13 ppb with 50 L sampling volume. The developed acid filter method is easy to deal with the field sampling and the method was adopted as the standard method for odor analysis in Korea.

The present study aims to develop a web-based model for English teacher evaluation, which purports to encourage a teacher to get actively involved in his or her own professional development through critical reflection upon teaching. The evaluation model using portfolio is based on the assumption that the teacher should play a key role in the evaluation process in order to bring about change in teaching. Another theoretical premise of the model is that data on teaching should be gathered from multiple sources such as observation, student performance and self-appraisal. The web-based model encourages stakeholders, e.g., administrators, headteachers, parents, to take part in the evaluation process. The model reflects the findings of a questionnaire survey on teachers’ perceptions on teacher evaluation and their needs. It is suggested that a number of factors related to administration, technology and content should be considered for the effective application of the model. Some suggestions are also made concerning evaluator training, time constraints, institutional support, and further research.

The first significant modern theatre movement in Korea arose in the early 1920s. Modern Irish drama and its theatre movement has always been a major field of interest for the Korean intellectuals and dramatists who believed that it provided a model for the modern Korean theatre. The importation of Irish drama was systematically conducted by different groups from the Korean intellectuals in the 1920s and 1930s, during which period many of them published articles concerning Irish drama and the Irish theatre movement. A famous Korean writer Hyo-Seok Lee(1907-1942) published an article titled 'A Research about John Millington Synge's Drama' in 1930, a compressed version of his BA degree essay in Monthly Dae-joong-gong-ron(Public Opinion). However, despite of his fame and popularity as a writer and material for academic research, this article has been forgotten and has remained unknown. Majority of Korean scholars concentrate on Lee's novel and essays while comparatively neglecting Lee's interest towards Irish drama. The main areas of discussions are the followings. First, socio-cultural significance of Irish impact on Korean theatre will be discussed. Second, in the context of Irish influence on Korean drama, the main feature of Lee's viewpoint towards Synge will be examined in comparison with other politically oriented Korean essays.

The mushroom production reached to 1000 billion won in monetary value in Korea. We, however, do not have systematic terminology dictionary published yet. Recently new varieties of medicinal mushrooms in addition to culinary mushrooms are being introduced steadily through out the world. This makes the necessity of coordinated and consistent arrangement of terms involved in culture, cultivation and physiological aspects of mushrooms. Various components in relation to the medicinal and physiological functionality also poses ambiguity in terminology along with the terms used in breeding and genetic researches. Moreover, some of the scientific terms are being used erroneously. In order to help mushroom cultivators, students, and mushroom business personnel in understanding the terms on mushroom science and technology we intended to collect and organize all the terms related to mushroom morphology and cultivation, poison and medicinal functionality, processing and utilization, and so on. Thirteen professionals from each field participated in this project. The fields included here are : 1) Genetics and breeding of mushrooms, 2) Cultivation and physiology of mushrooms, 3) Taxonomy and ecology of mushrooms, 4) Processing and functional components, 5) Blight and insects of mushrooms
