김효진,이상윤 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.4 No.1

Generally human, vehicular and environmental factors cause traffic accidents compositely. That is, usually it is said that human factors cause traffic accidents. But in traffic accidents, influences of road structures and traffic safety devices are not less important than that of human factors. Irrational road structures and traffic safety devices have much dangers of traffic accident, for it is needed for drivers to concentrate upon driving on these roads. So roads have to be planned safely, so that general drivers can drive without traffic accident occurred by circumstances in a ordinary attention and strain. Accordingly, we first have to grasp present conditions of where traffic accidents are often occurred, and then establish suitable countermeasures. Through these ways, we will be able to protect drivers against traffic accidents occurred by circumstances such as irrational road plans and traffic safety devices.

김효진,이상윤 경운대학교 산업기술연구소 2002 産業技術硏究論文誌 Vol.4 No.2

The factors of traffic accident are violation of drivers, defect of road structure, disorder of sidewalk and driveway etc. at high traffic-accident frequency spot. In these factors, defect of road structure, that is, defect in plan of road works the most important factor. Accordingly, in this thesis we will study on finding out causes and problems of traffic accident in aspect of traffic circumstance through statistical analysis, on-the-spot measure and investigation on the present condition of traffic at high traffic-accident frequency spot.

We evaluated the efficacy of the liquid form of enrofloxacin against poultry respiratory and digestive infections, the major problems in the poultry industry, from diverse diagnosis viewpoints. Results obtained through this study were as follows: 1. The liquid form of enrofloxacin showed good acceptability to poultry owing to no abhorrence to the drug by chickens, which indicated its suitability for mixing in drinking water. 2. The application of the enrofloxacin formulation improved the productivity of the chicken farm to a great extent by lowering the death toll of chicken raised in the farm. 3. The use of the drug shortened the days to the market, and increased the body weight at the time of marketing. 4. Preventive and therapeutic effects of the liquid enrofloxacin were observed higher than ampicillin, a major antibiotic used in poultry farming. From above results, the liquid form of enrofloxacin would find its use for the prevention and treatment of digestive and respiratory infections, let alone the growth promotion and feed efficiency, especially in the chicken farming practice.

TGA 방법을 이용한 플라스틱과 하수·분뇨슬러지의 열분해 반응속도 연구

윤효숙,최성필,김성탁,원양수,신부영 嶺南大學校 環境問題硏究所 1997 環境硏究 Vol.16 No.2

요약문 도시 고형폐기물의 열분해 특성에 대한 기초 자료를 제시하고자 열중량분석기를 이용하여 가열속도를 실험변수로 하여 하수 및 분뇨슬러지와 5대 범용 플라스틱인 LDPE, HDPE, PP, PS 와 PVC의 열분해 반응속도인자 및 분해특성을 파악하였다. 활성화에너지는 가열속도에 상관없이 일정한 값을 나타내었으며 분해속도가 최고일때의 온도는 가열속도가 증가함에 따라 증가하였다. LDPE, HDPE, PP와 PS는 1단계 분해반응으로 350∼520 ℃에서 대부분이 완전분해되었으며, PVC는 2단계 분해반응으로 250∼550 ℃에서 분해가 진행되었다. 슬러지는 여러 단계의 분해반응으로 특정한 분해구간이 없이 전구간에 걸쳐서 분해가 진행되었다. PVC를 제외한 플라스틱은 완전분해되었으며, PVC는 약 10%의 잔류량이 있었고, 슬러지의 잔류량은 D 하수, S 하수, T 분뇨 슬러지의 순으로 43, 70, 28.5%를 나타내었다.Abstract The thermal decomposition of sewage/night soil sludge and LDPE, HDPE, PP, PS and PVC was studied by using a conventional dynamic thermogravimetric analyzer (TGA) in a flowing nitrogen environment at several heating rates between 5 ℃ and 40 ℃/min. The dynamic thermogravimetric analysis curve was analyzed to obtain the information on the kinetic parameters such as activation energy, reaction order, and Arrhenius preexponential factor. The activation energy keeps constant regardless of heating rates, and the temperature of he fastest decomposition increases with the heating rate. LDPE, HDPE, PP and PS were completely decomposed in the temperature range of 350∼520 ℃ including as the first step decomposition and PVC was decomposed in the temperature range of 250∼550 ℃ including the second step decomposition. Sludge was decomposed without specific temperature range as several decomposition step. Except of PVC, all plastics were decomposed completely. PVC keeps the remains of about 10%, and sludge keeps the remains of 43% for D sewage sludge, 70% for S sewage sludge, 28.5% for T night soil sludge.

프랑스어 및 한국어 구강모음의 비교연구 : 컴퓨터 단층 촬영 및 디지틀 음향분광기를 사용하여 by means of Computed Tomography and High-speech Analysis System

The methods of the Computed Tomograph and the High-speed Speech analysis system were used for the comparative study of French and Korean oral vowels. Three male native speackers of French and three Korean speakers were selected for these articulatory and acoustic characteristics. The speech materials were the simple French oral vowels / i, e, ε, a, u, o, ??, a / and the Korean oral vovels / i, e, ε, a, w, u, o /, respectively. The results of these studies are as follows : (1) In the case of articulation, the aperture of Korean closed front unrounded vowels is larger than that of French vowels and the Korean back closed vowel /u/ and the half-closed vowel /o/ did not show significant differences with the corresponding French high vowel /i/. But the aperture of the Korean half-open vowel /??/ is smaller than that of French vowel and in this case, the place of articulation for Korean vowel /??/ is more advanced than that of French vowel /??/ (2) By means of spectrographic analysis of the French and Korean vowels, the first formant of the Korean high vowel /i/ is higher than that of French high vowel /i/. This means that the aperture of the Korean high vowel is larger than that of French high vowel. The second formant of French back vowels are lower than those of Korean back vowels. This result shows that the projection of French back vowels is greater than that of Korean back vowels.

윤효인,박승춘,이관복,김창식 충남대학교 수의과대학 동물의과학연구소 1994 動物醫科學硏究誌 Vol.1 No.-

Naproxen(NPX) was administrered to a throrougbred mare in a single oral does. Plasma and urine samples were collected from 1 hour to 144 hours after administration, at varying intervals. The alkali hydrolysis was used for the seperation of glucuronide from the conjugated naproxen and its metabolite in urine. Naproxen and its metabolite desmethylnaproxen (DesNPX) were extracted at pH 4.0 with DCM/ETHETR/HEXAN(1/1/1, v/v/v) and quantitated by HPLC with diode-array-detector. The wavelength of ultraviolet was 235, 254 and 264 nm. The qulification of NPX and DesNPX was performed by gas-chromatograph-mass spectrometry using DB-1 column. Silylation (BSTFA including 1% TMCS) before the analysis of the extracted residue with GC/MSD was carried out for the detection of this drug and its metabolite. The characteristic ions (m/e) of trimethyl Silyated NPX and DesNPX were 73, 185, 302 and 73, 243, 360, respectively.
