One of the ways to reduce abroad dependence for energy is to utilize solar energy when we are now confronted with not only insufficiency of natural resources but also the serious problems of environmental pollution. Therefore, full attention must now be paid to the development of solar energy system as alternative energy. To achieve this, solar hot water supply system was established at Chosun university, Gwang-ju, and experimental data were obtained based on meterological data and solar radiation. This study has been used the monthly mean values of the daily measurements obtained by data acquisition software Labview. This study shows Gwang-ju is a good region for the utilization of solar energy.

이정태,최윤정,전양환,성양숙,박원명,김광수,유태열 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.5

목 적 : 저자들은 자연최면경험과 최면감수성간의 관계를 알아보기 위하여 자연최면점수와 최면유도 척도로 얻은 최면유도점수 및 유도점수와의 관계를 알아보고, MBTI(Myers-Briggs Type Inventory)의 성격유형과 이들의 상호관련성을 알아보려고 하였다. 방 법 : 가톨릭대학교 의과대학에 재학중인 63명의 의대생들을 대상으로 하여 자연최면경험에 대한 설문지와 MBTI를 작성하게 하고 최면유도척도로 최면을 유도하면서 최면유도점수와 유도점수를 얻었다. 결 과 : 1) 자연최면점수와 유도점수 사이에서 양의 상관관계가 있었고, 최면유도점수와 유도점수 사이에도 양의 상관관계가 있었다. 2) 자연최면점수와 최면유도점수 사이에서는 통계적으로 유의한 상관관계가 없었다. 3) MBTI의 각 성격유형들은 최면유도점수와 유도점수 사이에서 양의 상관관계가 있는 것으로 나타났다. 4) 외향형과 사고형의 성격유형은 자연최면점수와 최면유도점수에서 각각 양의 상관관계가 있었고, 자연최면점수와 유도점수 사이에서도 양의 상관관계가 있었다. 5) 직관형과 판단형은 자연최면점수와 유도점수 사이에서 각각 양의 상관관계를 보였다. 결 론 : 자연최면점수는 유도점수와 상관관계가 있었다. MBTI의 외향형과 사고형에서는 자연최면경험이 많을수록 최면유도가 잘 된다는 것을 시사하였다. Objective : We attempted to investigate the relation between naturally occurring hypnotic experiences and hypnotizability. We examined the correlations among hypnotic induction profile scores, natural hypnotic scores, induction scores and MBTI personality types. Methods : Sixty-three medical students completed NHQ(natural hypnotic questionnaire) developed from a list of naturally occuring hypnotic-like experiences and MBTI(Myers-Briggs Type Inventory). HIP(Hypnotic Induction Profile) was also administered to all the subjects. HIP score and IND(induction score) were obtained. Results : 1) The NHS(natural hypnotic score) was significantly correlated with IND in all the subjects. The IND also showed significant correlation with HIP score. 2) There was no significant correlation between NHS and HIP scores. 3) HIP scores were positively correlated with induction scores in all types of MBTI. 4) Natural hypnotic scores were positively correlated with HIP scores and induction scores in introvert and thinking types. 5) There were positive correlations between natural hypnotic scores and induction scores in intuition and judgment types. Conclusion : The natural hypnotic scores were correlated with induction scores. It is suggested that the more the naturally-occurring hypnotic experience is experienced, the better the hypnotic induction is induced in introvert and thinking types of MBTI personality types.

브라켓 각도 변화에 따른 세라믹 브라켓의 마찰력 측정

차정열,김경석,김동춘,황충주 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.2

최근 사용되고 있는 세라믹 브라켓의 마찰력을 측정하고 비교하고자 실험군으로 3종의 세라믹 브라켓(Crystaline V(^®), Tomy, Tokyo, Japan; Clarity^(®), 3M Unitek, CA; Inspire^(®), Ormco, CA)을 사용하였으며 대조군으로 컴퍼짓 레진 브라켓(Spirit^(®), Ormco, CA)과 메탈브라켓(Kosaka^(®), Tomy, Tokyo, Japan)을 사용하였다. 활주 시 마찰력은 4개의 브라켓-교정선 경사(0°, 5°, 10°, 15°)에서 각각 측정되었으며 두 종의 교정선 [1. 스테인레스 스틸(Stainless Steel, SDS Ormco, Glendora, CA), 2. 베타-타이타늄(TMA, SDS Ormco, Glendora, CA)]이 사용되었다. 22mil 브라켓을 만능시험기기에 부착한 후 .021 × .025 크기의 교정선에 고무결찰한 후 34℃의 건조상태에서 5mm/min 속도로 교정선을 활주시켰다. TMA 교정선은 스테인레스 스틸 교정선보다 높은 마찰력을 발생시켰으며 모든 브라켓 호선과의 조합에서 브라켓-교정신의 각도가 증가함에 따라 정적, 동적 마찰력이 증가하였다. 0°~5° 구간에서 마찰력의 크기는 스테인레스 스틸 교정선과 레진 브라켓 조합이 가장 낮게 측정되었으며 다음으로 Crystaline V, 금속 브라켓, Clarity, Inspire의 순으로 나타났다. TMA 교정선에서는 Crystaline V와의 조합이 가장 낮은 마찰력을, 다음으로 컴퍼짓 브라켓, Clarity, 금속 브라켓, Inspire 순으로 나타났다. 5° 이상에서 마찰력이 급격하게 증가하였으며 스테인레스 스틸 교정선에서 레진 브라켓, Clarity, Crystaline V, 금속 브라켓, Inspire순으로 나타났다. TMA 교정선에서는 레진 브라켓, Crystaline V, Clarity, Inspire, 금속 브라켓 순으로 나타났다. 이때 호선 브라켓 조합에 대한 마찰력은 일반적으로 증가하였으나 마찰력 증가율의 차이로 인해 그룹간 마찰력의 순위가 서로 뒤바뀌는 경우가 관찰되었다. 실리카-삽입 세라믹 브라켓은 기존의 세라믹 브라켓보다 낮은 마찰력을 보여줄 뿐 아니라 브라켓-교정선의 경사도의 증가에서도 비교적 낮은 마찰력 증가율을 나타내어 세라믹 브라켓의 높은 마찰력을 감소시키는데 큰 역할을 할수 있다고 생각된다. The purpose of this study was to measure and compare the level of frictional resistance generated from three currently used ceramic brackets; 1, Crystaline V^(®), Tomy International Inc., Tokyo, Japan; 2, Clarity^(®), 3M Unitek, Monrovia, CA, USA; 3, Inspire^(®), Ormco, Orange, CA, USA; with composite resin brackets, Spirit^(®), Ormco, Orange, CA, USA; and conventional stainless steel brackets Kosaka^(®), Tomy International Inc., Tokyo, Japan used as controls. In this experiment, the resistance to sliding was studied as a function of four angulations (0°, 5°, 10°, and 15°) using 2 different orthodontic wire alloys: stainless steel (stainless steel, SDS Ormco, Orange, CA, USA), and beta-titanium (TMA, SDS Ormco, Orange, CA, USA). After mounting the 22 mil brackets to the fixture and .019 × .025 wires ligated with elastic ligatures, the arch wires were slid through the brackets as 5 mm/min in the dry state at  34℃. Silica-insert ceramic brackets generated a significantly lower frictional force than did other ceramic brackets, similar to that of stainless steel brackets. Beta-titanium archwires had higher frictional resistance than did stainless steel, and all the brackets showed higher static and kinetic frictional force as the angulations increased. When the angulation exceeded 5°, the active configuration emerged and frictional force quickly increased by 2.5 to 4.5-fold. The order of frictional force of the different wire-bracket couples transposed as the angle increased. The silica-insert ceramic bracket is a valuable alternative to conventional stainless steel brackets for patients with esthetic demands.

海苔 그리고 미역·톳養殖의 選擇性에 關한 硏究 : 自由에 對한 價値論的 接近

劉忠烈 釜山水産大學校 1985 論文集 Vol.35 No.-

In the beginning of 20th century Lever culture was adopted in Wando Islands. It depended for the market on Japan in the initial stage. The culture fishermen faced many difficulties in prices and export quantity. After the Liberation, however, Lever met domestic consumption. In this process, the culture fishermen obtained the stability in production and living. In the 1970s, Undaria culture was introduced and in 1975 Hijikia culture was also introduced. Axccordingly, Wando Islands have been able to culture these three kinds-Lever, Undaria and Hijikia. It is interesting, however, to notice that the selection of culture in these three kinds is very much similar to that of Wild-Culture. at present, the fishermen who selected the Hijikia culture gained more wealth, but the future market for Hijikia is not certain. The export quantity for Hijika is about 2,500 M/T. This quantity is too much for Japanese market because 300 M/T of the total quantity carries over annually, making inventories. Undaria is under export self-regulation and the export quantity is limited to 25,000M/T. but the consumption and prices for Undaria are rising in the Japanese market. The market for Hijikia and Undaria is limited to Japan. And Hijikia market conditions are not clear. This study dealt with the selection in culture of Lever, Undaria and Hijikia and attempted to make an analysis of the market condition of these seaweeds.

즉시 부하 교정용 미니임플랜트의 안정성 평가를 위한 Periotest 의 유효성

차정열,유형석,황충주 대한치과교정학회 2010 대한치과교정학회지 Vol.40 No.3

Objective: The aim of this study was to validate the Periotest values for the prediction of orthodontic mini-implants’ stability. Methods: Sixty orthodontic mini-implants (7.0 mm x Ø1.45 mm; ACR, Biomaterials Korea, Seoul, Korea) were inserted into the buccal alveolar bone of 5 twelve month-old beagle dogs. Insertion torque (IT) and Periotest values (PTV) were measured at the installation procedure, and removal torque (RT) and PTV were recorded after 12 weeks of orthodontic loading. To correlate PTV with variables, the cortical bone thickness (mm) and bone mineral density (BMD) within the cortical bone and total bone area were calculated with the help of CT scanning. Results: The BMD and cortical bone thickness in mandibular alveolus were significantly higher than those of the maxilla (p < 0.05). The PTV values ranged from -3.2 to 4.8 for 12 weeks of loading showing clinically stable mini-implants. PTV at insertion was significantly correlated with IT (-0.51), bone density (-0.48), cortical bone thickness (-0.42) (p < 0.05) in the mandible, but showed no correlation in the maxilla. PTV before removal was significantly correlated with RT (-0.66) (p < 0.01) in the mandible. Conclusions: These results show that the periotest is a useful method for the evaluation of mini-implant stability, but it can only be applied to limited areas with thick cortical and high density bone such as the mandible. Periotest는 보철용 임플랜트 식립 3 - 4개월 후 골유착 정도를 평가하기 위해 사용되는 동요도 측정 기기로 교정용 미니임플랜트 안정성 평가에 적용가능성이 높다. 본 연구는 교정용 미니임플랜트의 안정성 평가를 위해 Periotest 의 유효성을 검증하고자 하였다. 성견 다섯 마리의 상악, 하악 협측골에 교정용 미니임플랜트를 식립하고, 식립 시 식립 토오크와 동요도를 측정하고 12주 동안 교정력을 부여한 후, 제거 시 제거 토오크와 동요도를 측정하였다. 동요도 (Periotest value, PTV) 측정은 재현성을 위해 동일 부위에 2회 측정하였다. PTV와 다른 변수와의 상관성 분석을 위해 모든 실험견은 CT 촬영 후 식립 부위의 골밀도와 피질골 두께를 계측하였다. 동요도 측정에 대한 재현성은 0.96 의 상관계수를 나타내 매우 높았으며 (p < 0.001) 골밀도와 피질골 두께에 있어 하악골 협측치조골이 상악골에 비해 유의하게 컸다 (p < 0.05). 12주 동안 PTV 값은 -3.2에서 4.8의 범위를 나타내며 모든 임플랜트는 임상적으로 안정적이었다. 식립 시 PTV 값은 하악에서 식립 토오크(-0.51), 골밀도(-0.48), 피질골 두께(-0.42)와 상관성이 있었으나 (p < 0.05), 상악에서는 상관성이 없었다. 제거 시 PTV 값은 하악에서 제거 토오크(-0.66)와 상관성이 있었으며 (p < 0.05), 상악에서는 상관성이 없었다. 이상의 결과는 Periotest 를 이용하여 교정용 미니임플랜트의 안정성을 간접적으로 평가할 수 있으나 골밀도가 높고 피질골이 두꺼운 부위에서 제한적으로 응용할 수 있음을 시사한다.

誘致業種 選定에 關한 硏究 : 釜山地域 流通團地 造成에 따른

劉忠烈 釜山水産大學校 1983 論文集 Vol.31 No.-

During the recent two decades, Korean economy has been greatly developed by the export drive policy of the government. Therefore, governmental economic policies have been generally focused on the ways to increase domestic production and to improve the export competitiveness of domestic products, while the aspect of domestic consumption, especially that of distribution in domestic market, has been nearly disregarded. As the domestic market has grown accompanied by the economic growth, the problem of distribution in the domestic market has been raised as the urgent task upon the government, which induced to bear the Distribution Modernization Act of 1980. In Busan, the problem is more serious with shortage in the available space compared with population in the area, which the density of the area well accounts for. In this regard, the study aims at helping the establishment of the "Distribution Center in Busan Area" by providing appropriate industries for the center. Two variables are induced as the criteria on selection, that is, marketing cost variable and social benefit variable. According to the consideration by the two variables, the following industries are selected as the appropriate ones among the candidate industries. 1. Wholesale Market 1) Grain(Rice) Wholesale Market 2) Vegetable and Fruit Wholesale Market 3) Flower Wholesale Market 2. Terminal Station for Organized Retail Markets. 3. Cargo Transportation Terminal Additionally, a soft-ware for the effective administration of the Distribution Center is suggested.

漁港施設의 適正水準에 關한 硏究 : 釜山南港을 중심한 分析 With Main Analysis of Pusan Port

劉忠烈 釜山水産大學校 1983 論文集 Vol.30 No.-

The fishing ports can be patterned as follows: 1) Fishing ports specified by catch-species like Grimsby, Hull, Bremerhaven, Cuxhaven of European ports 2) Fishing ports specified by processing facilities, packers like some San Pedro, Pascagoula-Moss Point, Cameron of U.S.A. ports 3) Fishing ports specified by fishing ground like Japanese ports 4) Fishing ports specified by population density like Korean ports The fishing ports consist of various facilities, of which unloading facilities are the most important. Concerning the unloading capacity of Pusan fishing port, the length of the wharf is 406 meters and the average annual unloading weight is about 260,000 M/T, witch makes Pusan port the most congested fishing port in the world. Along the wharf, thirty vessels can unload per day by making ten vessels berth once. For the past three years(1979-1981), probability distribution of catches discharge per day was normal with arithmetic means, 28.36 vessels and the standard deviation, 10.21. Accordingly, it is estimated that the unloading weight will increase by 15%. In this case, the estimated probability distribution is 41.2% within thirty vessels and 58.8% over thirty vessels per day. In other words, the probability that more than thirty vessels should berth per day is 60% and so the investment is required for the solution of the congestion problem. And the limit of transaction quarter for the establishment of catch value is 60,000 boxes(20kg/box) and so the expansion for the transaction space is greatly needed.
