  • 본 논문에서는 광생물 반응기의 조명 시스템에 적용할 수 있는 LED(Light-Emitting Diode)와 태양광 하이브리드 광원을 이용한 도광판의 설계 및 제작 결과에 대해 보고한다. LED용 도광판 패턴을 설계하고 기존에 보고된 태양광용 도광판에 함께 중첩하여 가공하였다. 하이브리드 도광판의 출력 PFD(Photon Flux Density)를 일정하게 유지시켜주기 위한 제어 시스템을 제작하였으며, 출력 PFD 목표값을 $70{\mu}E/(m^2{\cdot}s)$로 설정하였을 경우 오차범위 ${\pm}2%$ 이내에서 제어가 이루어짐을 확인하였다.

  • This paper presents the comprehensive feasibility study of solar mini-grid project located in Bajhang District, Sudur Paschim Province, Nepal. The study has been conducted with the aim of developing a suitable size solar mini-grid system to meet electricity demand of proposed settlements of the village people. The study forecasts that the estimated average daily peak power consumption of load is about 20kW and average daily energy demand of load is about 100-150kWh/day in the base year 2022. The shared ratio of productive end uses is about 25% of the total power consumption and about 27% of the total energy demand, which will be used for small business/income generation activities and required 45kWp size solar power generation mini-grid system. The estimated project cost for the proposed 45kW solar mini-grid system technology, including 3 years of operation & maintenance, as well as power distribution network up to end user's premises is about 0.24 million USD. It is concluded that 45kWp photovoltaic mini-grid is feasible for the location.

  • 이 연구는 저주파 결함 탐지법을 이용하여 하중단계에 따른 암석 내부의 상태를 정량적으로 평가하는 것이다. CND에 의한 초기 종파속도는 X축 방향 1687.5 m/s, Y축 방향 1690.7 m/s, Z축 방향 1548.3 m/s이며, 평균 1642.2 m/s로 Z축 < X축 < (${\fallingdotseq}$)Y축 관계를 보였다. 실버슈미트 해머에 의한 Q값의 전체 평균은 62.6으로 약 105 MPa의 일축압축강도에 해당되었다. 저주파 결함 탐지기에 의해 측정된 하중단계 50%, 60%, 70%, 80% 수준에서 종파속도 크기는 X축 < Y축 < Z축 순으로 대체적으로 하중단계가 증가함에 따라 감소하는 경향을 보였다. 하지만, 이들 값은 초기 종파속도와 다른 경향을 나타냈다. 하중단계가 증가함에 따라 Y축이나 Z축 방향보다 X축 방향의 종파속도를 감소시키는 요인이 더 많은 영향을 미쳤기 때문으로 판단된다. 이러한 사실은 암석 내부의 초기상태는 응력상태가 변화함에 따라 다르게 나타날 수 있다는 것을 의미한다.

  • Jang Heung Lim's is a nephew's wife of Kim Duk Ryung, who had been served as a general of Chosun dynasty. When her Tomb was removed to another places there were excavated some articles such as six Korean traditional costume, Korean socks, Korean shoes (Mituri) and so on. The unearthed costume was designated as a monentous folk materials, No.112, and placed on Gwangju folklore museum. At that time, the mending work in the lost part of costume was not implemented. Only an act of textile conservation was worked. In the article, we go through the mending principles and mending methods in damaged parts of costume. First, the mending principles on the damaged costume are as follows : (1) minimize the repaired parts, (2) mend the only damaged parts, (3) use the same color and cloth as that of original ones, (4) use the appropriated stitching method (5) act the fixed framework in case of missing a outer cloth. Second, the mending method related to the damaged part are as follows : (1) the repairing method in the bodice and sleeve part of costume, (2) the repairing method in the hem of steeve, (3) the repairing method in the collar of costume, (4) the repairing method in the armpit part of costume, (5) the repairing method in the connecting parts between one and another width of Korean traditional long skirt. With this article, we wish that the repairing method in the cultural costume will be developed scientifically and specified efficiently.

  • Since the year 1795(in the 19th year of King Jungjo), the form of Banquet Record was established. In the year 1827(in the 27th year of King Sunjo), the formality of Banquet was made at Ja-kyung Palace for the first time. Thereafter it was utilized by all banquets, So it was called the“model of courtesy”. The compostion of Jinchan Uigue of the year 1887(in the 24th year of King Gojong) was identified as follows; Banquet Record was composed of 4 Volumes.

  • 본 임상연구는 상아질지각과민증을 치료하기 위한 여러 가지 방법 중 효과적인 방법의 하나로 알려져 있는 불소(NaF)를 이용하여 불소테이프(SCMC-T-5)를 개발, 제조하고, 이를 이용하여 상아질 지각과민 치료 효과를 기존의 불소바니쉬(Cavity $Shield^{TM}$)와 비교, 평가하였다. 상아질 지각과민증이 있는 건강한 20대 남녀 22명(88개 치아)이 본 임상연구에 참가하였으며, 각각 11명씩 불소테이프를 부착시킨 실험군과 불소바니쉬를 도포한 대조군으로 분류하였다. 불소 제제는 제조사의 지시에 따라 적용되었으며, 불소 제제 도포 전, 도포 3일후, 1주일 후, 4주일 후 대상치아에 압축공기와 얼음막대를 이용하여 자극을 가한 뒤 visual analog scale(VAS)을 이용하여 통증 정도를 표시하도록 하였다. 실험군에서 VAS scores는 초기에 38.636(air), 62.273(ice), 3일 후 30.273(air), 49.545(ice), 1주일 후 28.182(air), 40.000(ice), 4주일 후 26.364(air), 37.727(ice)이었으며, 초기 VAS socres에 비해 모든 VAS scores는 통계학적으로 유의성 있게 감소되었다. 대조군에서 VAS scores는 초기에 42.274(air), 65.909(ice), 3일 후 34.091(air), 55.909(ice), 1주일 후 28.636(air), 40.909(ice), 4주일 후 27.727(air), 31.364(ice)이었으며, 3일 후에 시행된 압축공기에 의한 자극검사를 제외한 모든 VAS scores는 초기 VAS socres와 비교했을 때 통계학적으로 유의성 있게 감소되었다. 본 임상연구에 사용된 불소테이프와 불소바니쉬는 상아질 지각과민증을 효과적으로 감소시켰고, 두 약제간의 치료효과의 차이는 없었다.

  • 더 빠른 절삭속도와 이송속도를 위한 고속가공은 표면품위와 재료제거율의 증가를 초래한다. 이 논문은 고속가공을 위한 정면밀링커터를 사용한 가공에서 획득된 진동특성에 관한 절삭조건의 영향을 연구하였다. 이 논문에서, 직교배열 테이블에 기초한 다구찌 실험계획법은 고속 정면밀링커터를 사용한 진동특성을 연구하기 위해 적용되었다. 실험조건은 직교배열 $L_{27}(3^{13})$ 을 사용하였다. 실험의 계획과 분석은 S/N비(신호 대 잡음비)와 분산분석을 이용하여 진동에 관한 절삭조건의 영향을 연구하기 위해 수행되었다. 절삭 파라미터 즉 이송속도, 챔퍼길이, 절삭속도 그리고 절삭깊이는 진동 특성치를 고려하여 최적화 되었다.

  • The desire for the healthy life is increasing as a result of rapidly changing social and economic environment in Korea. Because of the need, informations on health, food and nutrition are being introduced through the mass media. The object of this study is to investigate and analyze the quantity and quality of informations about health, food and nutrition in women's magazines. Six representative domestic monthly magazines(Lady Kyunghyang, Women Donga, Women Chosun, Women JoongAng, Women sense, Jubu Senghwal) were selected for this study. The results of monitoring from June 2002 to September 2002 for the women's magazines were summarized as follows; 1. The percentage of the articles on health, food and nutrition by total area of the women's magazines was 23.1%. There were total 595 articles on health, food and nutrition. Among these, 400 articles(67.2%) were about food and nutrition. 2. The percentage of the advertisements on health, food and nutrition was 35.3% by total area of the woman's magazines. There were 2,353 advertisements on health, food and nutrition. Among these, 1,574(66.9%) advertisements were about food and nutrition. The most frequently advertised advertisements on food and nutrition were about processed foods (527 cases, 33.5%). The second most frequently advertised advertisements were about diet (374 cases, 23.8%). The third one was healthy foods (345 cases, 21.9%). 3. The contents of 215(53.8%) articles (the total number of articles was 400) was suitable. The contents of 89 advertisements(22.3%) did not have accurate informations on health, food and nutrition. For the advertisements in women's magazines (the number of total articles was 2,203), the percentage of the advertisements which was not able to capture the feature of the advertisements was 27.9%, insufficiency of reliable sources was to 21.9%, and exaggeration of the contents in the ads was 16.0%. Articles and advertisements should be backed by scientific research or reliable sources and also the opinions of people with expertise in order to report accurate informations to the general public. In order to achieve these results, there should be continuing monitoring activity for the women's magazines.
