Phthalic anhydride(PA) is widely used in the production of alkyd and unsaturated polyester resins. It has been reported that some workers exposed to PA have developed dermatitis, rhinitis and asthma. The authors intended to investigate the prevalence of PA induced allergic diseases and to develop preventive measures of occupational diseases. Forty-five male workers from PA production and handling were selected as an exposure group. Forty-four male workers not handling PA at tie same factory were chosen as a reference group. A symptom questionnaire, doctor's examination, eosinophil count, serum-total IgE and PA-specific IgE were done on the subjects. There were no significant differences in age, educational level. tenure or smoking habits between groups. Most clinical symptoms were significantly more frequent among the exposure group than the reference group: sneezing(62.2%), rhinorrhea(57.8%), nasal stuffiness(53.3%), coughing(44.4%) and nasal itching(35.6%) were the major symptoms among the exposure group(p<0.01, p<0.05). There were no significant differences in eosinophil count and serum-total IgE between groups but the mean level in PA-specific IgE, in the exposure group, was statistically significantly higher than the reference group(p<0.01). Abnormal rates of eosinophil count, serum-total IgE and PA-specific IgE were not significantly different from each other. The prevalence rate was 68.9%(31 cases) for allergic rhinitis in the exposure group, statistically significantly higher than the reference group(p<0.01). The prevalence rate was 6.7%(3 cases) for bronchial asthma and contact dermatitis in the exposure group, not more statistically significant than the reference group. In the exposure group, the prevalence rate for age, educational level, tenure, smoking habits and use of protective devices are not statistically significant. In PA specific IgE, sensitivity is 10.8%, specificity is 100.0%, positive predictability is 100.0% and negative predictability is 61.2% when criteria point is 3.5 KU/ιor above. As a result, it was recognized that the exposure group had a high prevalence of PA induced allergic rhinitis. Also, in diagnosis of PA induced allergic diseases, medical histories and specific symptoms were the most important where as eosinophil count, serum-total IgE are the only indirect informations. PA-specific IgE has been needed to evaluate the meanings more.

3-D 동작 분석 장치를 이용한 한국성인(20대, 30대)의 동작 범위에 관한 연구

Devices, such as a goniometer, have been used to measure a human being's active range of motion, but interferences between subjects and testers have affected the result precision. In this study, 56 dynamic motion ranges were measured using a 3-D motion analysis system which is quite accurate (2mm error for 1m). The 3-D motion analysis system consists of VICON 140, data acquisition system, and data analysis program (KRISSMAS). 80 Korean subjects (40 males, 28±6.1 aged and 40 females, 28.4±6.9 aged) participated. Subjects were divided into 4 groups by Ro¨hrer's index based on National Anthropometric Survey of Korea 1997. Basic statistical analysis were performed using SPSS (ver. 8.0) programs after refining data. Various comparisons were performed for the right and left side, male and female, age groups (20's, 30's. and 40's-60's) using previous studies. The results show that female subjects have more flexible joints in the neck, hip, ankle, and wrist, while male subjects have more flexibility in their waist. But most of the significances were not high (>0.05). The prediction that the right side of Korean bodies would be mort flexible was not a good hypothesis. And the joints flexibilities are not correlated with Ro¨hrer's Index.

임현수 충남대학교 의과대학 지역사회의학연구소 2001 충남의대잡지 Vol.28 No.1

A new diode laser system for therapy of cancer is proposed in this paper. In order to accuracy and statistical output control we used the constant current control method and designed the power source to protect the resonator from the over-current, rush-current and electrical fault. The most important things are the radiation type for cancer therapy in laser system, we developed the radiation type of cw, long pulse, and burst pulse. The experimental result show that laser beam power increase linearly from 10mW to 300mW for input current increasing and the exposure time.

The decrease of environmental and body temperature showed change of blood components.

대중국의 재해석 : 연극과 영화 <8명의 여인들 Huit emmes> 의 비교 연구

임수현 서울여자대학교 2011 인문논총 Vol.21 No.-

본 논문은 이러한 인식을 토대로 하여, 토마의 연극 <8명의 여인들> 이 지닌 연극성과 대중극으로서 면모가 오종과 스타 여배우들의 영화 <8명의 여인들> 을 통해 어떤 식으로 복합성과 다양성을 지닌 텍스트로 재탄생하게 되는지를 살펴보고자 한다. 연극과 영화라는 매체에 대한 비교는 보다 전문적이고 미학적인 연구가 필요하겠지만, 본 논문은 <8명의 여인들> 한 작품에 국한시켜 각색을 통해 원본의 장점을 강화 하면서도 한계를 뛰어넘는 양상들을 살펴보는 데 초점을 맞추게 될것이다. Notre etude a pour objectif de comparer le théâtre "HuitFemmes" de Robert Thomas avec son adaptation cinématographique de FranÇois Ozon, pour on reconnaître les aspects spécifiques de ce texte et les modalités do sa nouvelle interprétation. Appartenant á la tradition du théâtre de boulevard des années soixante, Thomas met on scéne, dans cette piéce, une famille bourgeoise en crise causée par la mort du “pére” de la maison. Il s’agit d’une comédie policiére, une enquête à suspense menée par les members de la famille, les ‘huit femmes’. les'huit femmes'. L'originalité de cette piéce semble résulte de deux choses, d'une part de l’intrigue 'bien faite' avec nombreux coups de théâtre, a la Agatha Christie ou à la Alfred Hitchcock, et d'autre part, des figures originales des personnages feminins, qui s’impllquent entre elles, chacune se révélant une feminite particuliere.

임현수,이병철 충남대학교 의과대학 지역사회의학연구소 1991 충남의대잡지 Vol.18 No.1

In this paper, a method of the measument the degree of the musule fatigue by short Time Fourier Analysis of the EMG signals from human biceps in the action state is proposed. For this purpose, fatigue state and recovery state of 10 persons EMG signals are sampled. And then spectrum centroids are analyzed with respect to the change of sample time window. As result of 10 persons experiment, we know that person A is most good recovery state.

Animal virus의 최대 생산을 위한 환경인자에 관한 연구

임현수 여수대학교 1998 論文集 Vol.13 No.2

pH, 혈청 농도, polycations등과 같은 환경인자들이 바이러스 생산에 어떠한 영향을 미치는지 조사하였다. pH의 범위가 6.6에서 8까지의 사이에서는 VSV(vesicular stomatits virus)의 생산에 아무런 영향을 주지 않았고, 최적의 MOI(multiplicity of index)는 0.1에서 나타났다. Polycation의 첨가시 바이러스의 숙주부착속도가 현저히 증가함을 알 수 있었고, VSV production(1.7*?? pfu/ml)은 대조구(5.5*pfu/ml)보다 약 3-4배 증가함을 알 수 있었다.

임현수 麗水水産大學校産業技術硏究所 1997 産業基術硏究所 論文集 Vol.6 No.-

일반적으로 뉴캣슬병은 Paramyxo-Virus로 인하여 전염되는 강력한 가금류병이다. 이 병에 대한 백신의 성장은 10일란을 숙주로 사용하여 이루어지나 무균란의 가격이 비싸고, 공정의 제어 및 제품의 균일화가 어려우며, 계란껍질과 같은 폐기물의 발생이 높은 단점이 있다. 이를 극복하기 위하여 10일란의 1차 세포배양방법을 살펴보고, 이 세포를 숙주로하여 뉴캣슬병 바이러스(NDV)를 생산하였다. 1차 세포주(CEF)는 in-vitro 배양에서 잘 자라지않는 특성을 가지고 있으나, 다공성 담체를 사용한 결과 생체 조직과 유사한 3차원적인 배양이 가능하여 다른 담체에 비하여 높은 성장(5.3×10(6)cells/ml)을 보여주었다. 바이러스의 생산성은 일반적인 담체인 Cytodex-3보다 4배 가량 증가된 농도인 2.1×10(10)pfu/ml로 나타났으며, 조직배양용 플라스크를 이용한 산소분압에 따른 바이러스의 생산을 살펴본 결과 10-21% 분압에 대하여는 유의한 효과가 없었다. 그러나, 숙주로 Vero 세포주를 사용하였을 경우 1% 산소분압에서 약 10배의 생산성 증가를 가져왔다.

임재근,서강수,문현욱,신용진 明知大學校 産業技術硏究所 1992 産業技術硏究所論文集 Vol.11 No.-

This thesis is the study on the magnetic properties of strontium (Sr) ferrite. Specimens of SrO·nFe₂O₃,basic composition, with n=5.9 which is nonstoichiomatric composition region were prepared by sintering at 1275°C for 1hr, whthin air surroundings. In order to increase coercivity, additives of 0.4wt%SiO₂ and 0.7wt%CaCO₃ were added into basic composition, and 0.5wt%∼2.0wt%Cr₂O₃ was added as second additives. In case of second additives 1.5wt%Cr₂O₃, it was obtained uniformed grain size and magnetic properties was increased. The sintering temperature was 1150°C, 1180°C, 1210°C, 1240°C and 1270°C respectivily and cooling was performed in furnance. From the research and experiments on the magnetic properties of strontium (Sr) ferrite based on the complex additive technique, it was obtained good magnetic properties of (BH)mas=0.72MGOe, at the sintering temperature of 1210°C, in the case of (basic composition)+(basic additive)+(1.5wt%Cr₂O₃)
