권오경,문제기,손부헌,최영희 한국의류산업학회 2003 한국의류산업학회지 Vol.5 No.4

In this study, we measured the antibacterial activities, deodorization, UV cut ability, whiteness and SEM, according to the size(5 μm, 15 ?m) of ThiO₂, concentration(3%, 5%, 10%) and dipping temperature(50℃, 70℃) with using anatase type of TiO₂ photocatalyst. Photocatalyst is the substance which carries out functions, such as decomposition, removal, deodorization, antibacterial, etc. of a contaminant, in a place with light based on an oxidation-reduction reaction. The results of this study were as follow. Antibacterial activities are increased with increasing of the TiO₂'s concentration, and TiO₂ has high antibacterial activities for Staphylococcus aureus but it has low antibacterial activities for Klebsiella pneumoniae. The deodorization and UV cut ability is very good, therefore be able to get good effects with usingonly 3% of TiO₂. Every effects are increased by using small size of TiO₂ and high dipping temperature.

This study was undertaken to provide the fundamental information and the optimum method of municipal solid wastes(MSWs) in Masan city. The result of physical and chemical properties and the analysis of calorific value was represented as the region of residence, commerce, office/industry and the other. The ratios of apartment, individual residence, commerce, office/industry and the other as waste source were 26.5, 34.3, 26.2, 5.2 and 7.8%, respectively. The ratios of spring, summer, autumn and winter according to the season were 27.3, 26.4, 26.0 and 20.3%, respectively. The physical composition showed that the combustible and the noncombustible occupied 88.5 and 11.5% each other. In case of three component analyses in Masan city, the moisture and the combustible were 44.9 and 50.2% and also the ash was shown 4.9%. The chemical compositions through the analysis were C(26.06%), H(3.28%), 0(19.48%), N(0.8%), S(0.07%) and Cl(0.49%). When the wet low-calorific value was investigated, the measured value was 2,413 kcal/kg and the estimated values in response to the equations of Steuer, Dulong and Japan's experienced were 1,936, 1,724 and 3,372 kcal/kg, respectively.

진주지방의 기후특성에 관한 연구 : 기온변화에 대한 통계적 분석 On the Statistical Analysis for the Temperature

이부권 慶尙大學校 1984 論文集 Vol.23 No.2

진주지방에서 관측된 1915년부터 1983년까지 1950년을 제외한 68개년 일기온(최고, 평균, 최저기온)자료를 이용하여 1월 1일부터 12월 31일까지 365일 각각에 대해 산술평균하여 이 지방의 표준기온을 산출하였다. 이것에 의하면 기온분포가 최고일로부터 좌우대칭이 아님을 알 수 있고 같은 날짜의 기온에 대하여도 그 표준오차가 대략 3℃-4℃정도로 큼을 알 수 있었다. 그리고 일기온을 표시하는 시간함수를 회귀분석에 의해 정현함수 꼴로 구하였다. 모형은 대체로 실제를 잘 반영하였다. 모형과 자료사이의 편기는 자료가 정확한 대칭이 아닌 데서 주로 기인되었다. 이러한 편기는 5월중순부터 7월 중순까지에 가장 심했다. 그리고 이 모형을 이용하면 적산온도 평균온도 등 여러 가지 기초정보를 쉽게 얻을 수 있다. From the meteorological data(1915.1.1-1983.12.31.) the standard temperatures in Jinju was estimated throughout the years. The distributions of the standard temperatures including the maximum, the minimum and the average temperatures were symmetrical but not exactly fitted to the estimated curves during the period of May to July by showing lower temperatures during the period than the symmetic curve. Fluctuations of the daily temperature were significant with a standard deviation of 3 to 4℃. From the regression analysis the function of temperatures to the time of a given day was described as a typical sinusoidal. With high efficiency the temperatures could be estimated from the function. Some biasedness found in the estimation of the real temperatures by the equation seemed to be ascribable to the matter of symmetry during the period. If the model is good enough to use, it was easily feasible with the model obtain useful informations on various temperatures such as the accumulated, average temperatures etc. in any arbitrary time period.

장현석,임재석,권종진,이부규,손형민 대한악안면성형재건외과학회 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.3

Purpose : The purpose of this study was to analyze the lower third facial changes in frontal view after mandibular setback surgery. Materials and Methods : In this study, fifteen subjects(6 males and 9 females) with class III dental and skeletal malocclusions who were treated with BSSRO(Bilateral Sagittal Split Ramus Ostetomy) were used. Frontal cephalometric radiographs were taken preoperatively and more than 6 months postoperatively, and hard tissue(H2-Hl) and soft tissue changes (S2-S1) were measured on vertical and horizontal reference lines. In 15 cases, changes which developed more than 6 months after surgery were studied. Results : The results were as follows. 1.In the facial height, hard tissue decreased(2.46±2.76mm) with statistical significance(P<0.01), and soft tissue also decreased(1.64±3.66mm). As a result, the facial height generally becomes shorter after sagittal split ramus osteotomy. 2.In the mandibular width, hard tissue decreased(2.08±3.59mm) with statistical sgnificance(P<0.05), but soft tissue increased (2.14±5.73mm) without statistically significant difference (P>0.05) postoperatively. 3.In the facial index, hard tissue decreased(0.23±2.21%), but soft tissue increased(2.41±3.46%) with statistical significance. Conclusion : One of the main purpose of orthognathic surgery is to achieve facial esthetics and harmony. In order to fullfill this purpose, it is important to carry out a precise presurgical treatment planning by estimating the changes of frontal profile after surgery.

The results obtained were as follows; the monthly, seasonal and yearly distribution of the average number of days with the weather phenomena were listed in Table 1 and 2. Monthly distribution of the maximum frequency and its appeared year with the weather phenomena were listed in Table 3 and 4. The distribution of the annual and seasonal mean number of days with the weather phenomena were plotted on Fig. 1-5.

農機械의 適正需要推定

李正漢,黃弘道,李富權 慶尙大學校 1981 論文集 Vol.20 No.2

The primary objective of this study is to provide projection of optimum, demand for farm machines such as farm tractors, power tillers, rice transplanters, combines and grain binders, and to provide policy directions for farm mechanization. In order to carry out this work, this study attempts to formulate a recursive programming model with size of 119 by 161 matrices involving various endogeneous and exogeneous variables, and to estimated their parameters. The recursive programming model is constructed by an objective function to minimize total domestic resources costs subject to various resources restraints and various activities. From the constructed recursive programming model, this study attempts to carry out a sensitive analysis in order to provide alternative projections of demand for the five farm machines, and to recommend policy directions for farm mechanization. By the way, this sensitive analysis is carried out by introducing the selected three policy variables such as price of farm machines, importing price of food-grain, and decreasing rate of farm population, and the given two conditions of each policy variable. It should be noted that these policy variables are determined as the most important factors affecting the demand for farm mechanization through results estimated by the recursive model. However, from the results of the alternative projections of demand for the five farm machines based on the sensitive analysis, this study provide a recommended projection for farm mechanization, and it is expected that the level of farm mechanization is greatly affected by the rated of self-sufficiency in food grain and off-farm employment opportunities.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.
