The study examined qualification test of the 1st term Animal Nurse Technician and conducted questionnaire survey as well as site investigation to settle Animal Nurse Technician system in Korea. The objects were undergraduates, graduates and director of animal hospital. 115 applicants applied to the qualification test of animal specialists, and 50 applicants passed the test to record 43.47% of ratio of successful applicants. The subjects having relative difficulty were anatomy physiology and public hygiene to record 19 points in average: In particular, the anatomy physiology recorded 35 points of the highest score and 6 points of the lowest score to have the highest deviation and to require adjustment of difficulties. 89.2% of the interviewee supported needs of animal nurse technician system in Korea to show positive response. At the survey of actual conditions of recruitment of animal nurse technicians at animal hospitals, 28.6% of the interviewee was employing the technicians, and 35.7% had employment plan, and 32.1% wanted to employ them under good conditions. In other words, 96 4% of the interviewee responded positively, while no more than 3.6% did negatively. In Korea, the animal nurse technicians had roles as follows: The animal hospitals gave priority to reception service and customer controls followed by medical examination support,whilethecollegesdidtomedicalexaminationsupport. To differentiate hospitals in accordance with the increase of number of animal hospitals, the animal hospitals should employ animal nurse technicians having specialty and qualifications on animal nurse technician examination. In particular, the roles and demand of animal nurse technicians were expected to grow because of developed technologies of veterinary medical science, development of medical supplies and instrument, and the increase of aged animals, etc. Therefore, job analysis on animal nurse technicians should be done to adjust the subjects of qualification test and to develop questions.

To develop an efficient degradation system for Endocrine disruptors (EDs), it is necessary to have a good system to evaluate rapidly and accurately endocrine-disrupting activities of suspected chemicals and their degradation products. We previously constructed a co-expression system of GAL4 DNA binding domain (DBD)-human estrogen receptorβ ligand binding domain (hERβ LBD) and Gal4p transcriptional activation domain (TAD)-co-activator SRC1 in Saccharomyces cerevisiae with a chromosome-integrated lacZ reporter gene under the control of CYC1 promoter and GAL4 binding site (Upstream Activating Sequence, UAS). Expression of this reporter gene was dependent on the presence of estrogen or endocrine disruptors in the culture medium. Furthermore, the extent of transcriptional activation by those chemicals correlated with their estrogenic activities measured by other assay systems, indicating that this assay system is efficient and reliable for measuring estrogenic activity. We applied this assay system to measure estrogenic activity of microbial degradation products of γ-hexachlorocyclohexane (γ-HCH) by Sphingomonas paucimobilis. Among the γ-HCH metabolites, 2,5-dichlorohydroquinone (2,5-DCHQ) and chlorohydroquinone (CHQ) had similar estrogenic activities to the original chemical, but hydroquinone (HQ), a metabolite at later stage, had no activity at the concentration of 10^-4M, showing the necessity of evaluation of intermediate metabolites in microbial degradation systems.

물-공기 계면에서 표면압력의 증가에 따른 C30DME 분자의 구조 변화를 살펴보았다. 표면압력(π)-표면적(A) 등온선을 통해 표면적이 줄어들 때 C30DME 분자가 선형으로부터 역 U 자형 구조로 변하는 것을 확인하였다. C30DME의 역 U 자형 구조의 형성을 확인하기 위하여 Surface Plasmon Resonance (SPR)와 ellipsometry를 이용하여 Langmuir-Blodgett (LB) film 의 두께를 측정하였고 이 두께는 C30DME 분자의 역 U 자형 구조의 높이와 일치함을 관찰하였다. 또한 Atomic Force Microscope (AFM)을 이용한 표면 거침도 측정의 결과는 선형으로부터 역 U자형 구조로의 구조적 변화가 불연속이라는 것을 보여주었다. We investigated the conformational change of C30DME molecule with an increase on surface pressure at the air-water interface. The surface pressure (π)-area (A) isotherm indicates that the structure of C30DME changed from linear to reverse U-shape as the surface area was compressed. In order to confirm the formation of reverse U-shape, we examined the thickness of Langmuir-Blodgett (LB) film by a surface plasmon resonance (SPR) and an ellipsometry. The result of surface roughness measurement using an atomic force microscope (AFM) showed that the conformational change from linear to reverse U-shape is discontinuous.

Limited landfill area and finance as well as a huge generation of waste, have called for systematic approaches towards potential cost savings. In this study, the management system of food wastes generated from the residential and commercial sources was considered in three citied; Changwon, Masan, and Jinhae city. Total thirteen alternatives were established and compared by applying the WRAP (Waste Resource Allocation Program). The following results were obtained: 1. While relatively small amounts were generated form the commercial sources such as cafeteria, restaurants, and market facilities, almost 80% of food wastes were generated from the residential sources. 2. Unit costs for food waste management in three cities were different according to their present situation, and the highest cost appeared in Jinhae city due to the most expensive construction of coastal landfill site. 3. Considering proper revenue, the whole conversion of food waste into animal feed was selected as the optimal alternative and represented 60% to 74% of management cost of the whole landfill alternative in all cities. Comparing the other alternatives, composting of food waste was more economical than the landfill alternative and the incineration was the most expensive alternative.

TCP Vegas는 TCP Reno에 비해 안정적이고 이로 인해 네트워크 자원을 보다 효율적으로 이용할 수 있다. 그러나 두 버전이 같이 사용되는 경우 TCP Reno에 비해 TCP Vegas는 일정하나 낮은 수준의 전송율을 보이고 있다. 본 논문에서는 TCP Reno와 Vegas의 공정성에 영향을 미치는 요소인 TCP Vegas의 알고리즘에서 사용하는 상수 요소인 α·β, TCP의 MSS, 라우터의 버퍼 크기에 의해 TCP Reno와 TCP Vagas의 공정성이 변화하는 모습을 시뮬레이션을 통해 확인하였으며, 이에 따른 향후 연구과제를 제시하였다. TCP Vegas are much more stable than those of TCP Reno, resulting in a much more efficient utilization of the network resource. But difference in performance in due to the fact that Teno vibrates in the high throughput level and Vegas almost stabilizes in the low level when those TCP versions are used in same network. We find out by simulation about α·β which is constant factor of TCP Vegas, MSS of TCP and router buffer size change the fairness of TCP Reno and TCP Vegas. So we proposed more studying about these factor which changes fairness of TCP Reno and TCP Vegas.

1994년도 한 대학 1년생을 대상으로 8개항목의 생활만족지수(LSI-W) 그리고 20개항목의 우울지수(CES-D) 및 관련변인들을 조사하여 각각의 점수와 우울증의 유병률을 계산하고 서로간의 관련성을 조사하여 다음과 같은 결과를 얻었다. 1. 생활만족지수의 평균점수는 9.98이었고 비흡연군, 비음주군, 운동을 하는 군에서 평균점수가 유의하게 높았다(p<0.01). 2. 우울지수의 평균점수는 17.2였고 여학생에서 남학생보다 유의하게 높았고, 우울증의 유병률은 19.8%이었고 여학생에서 남학생보다 유의하게 높았다(p<0.01). 3. 우울증세 고위험군과 저위험군에 있어서 건강에 대한 본인의 생각과 본인이 인지하는 체중에서 차이가 있었으며, 생활만족지수, 가족수, 체중, 신장에서 유의한 차이를 보였다(p<0.05). 4. 우울지수와 생활만족지수, 연령, 종교활동기간, 신장, 체중등과는 음의 상관을 나타내고(p<0.01), 가족수, 수면시간, 경제수준과는 양의 상관을 보였다(p<0.01). 5. CES-D에 영향을 미치는 변수를 알아보기 위한 단계적 로지스틱 회귀분석에서 생활만족도, 성별, 건강에 대한 본인의 생각, 본인이 인지하는 체중, 흡연, 음주가 CES-D에 의한 우울증 발현에 있어서의 유의한 요인으로 나타났다(p<0.05). The questionnaire survey using the Center for Epidemiological Studies-Depression Scale(CES-D) and 8-items Life Satisfaction Index Well-being(LSI-W) and other variables was conducted to determine the prevalence of depression and to identify the correlation among CES-D and related factors. Study population was the whole freshman group newly enrolled in a university. The results were as follows; 1. Mean score of LSI-W was 9.98 and that score was higher in non-smokers, non-drinkers and exercise group (p<0.01). 2. Mean score of CES-D was 17.2 and the prevalence of depression was 19.8%. And those were significantly higher in female than in male(p<0.01). 3. Perceived health status, perceived weight, LSI-W, family size, weight and height were significant variables between high and low risk group of depression(p<0.05). 4. CES-D score was negatively correlated with LSI-W, age, duration of religious life, height, weight and po-sitively correlated with family size, sleeping time and economic status(p<0.01). 5. In the regression analysis significant predictors of the depression were sex, preceived health status, weight, smoking and drinking(p<0.05).

이명수,오은영,조선미,홍만제,문재석 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.4

연구목적 : 본 연구는 한국 청소년들의 인터넷 사용 현황조사와 더불어 인터넷 중독증과 우울, 사회적 불안, 또래관계 문제등과의 연관성을 알아보고자 하였다. 방 법 : 수원시 소재 고등학교 학생 869명(남/여=371/498)을 대상으로 인터넷 사용과 연관된 기본 설문을 실시하였다. 인터넷 중독여부를 알아보기 위하여 Young의 인터넷 중독척도를 사용하였고 우울증상의 평가는 Beck Depression Inventory(BDI)를 사용하였다. 사회적 불안 및 회피정도는 Social Avoidance and Distress Scale을, 부정적 평가에 대한 두려움 측정은 Fear of Negative Evaluation-Brief척도를 , 또래관계의 문제는 Index of Peer Relations척도를 사용하였다. 인터넷 중독의 현황조사를 위해서 실수와 백분율, chi-square test를 실시하였고, 인터넷 중독증과 우울, 사회적 불안 및 또래 관계 문제의 연관성을 알아보기 위하여 일원변량분석(ANOVA)을 실시하였다. 결 과 : 1) 총 869명의 대상자 중 남학생이 371명(43.7%)이었으며 여학생이 498(57.3%)이었고 평균연령은 16.27세(표준편차=0.82)로 남녀간에 유의미한 차이는 없었다. 2) 총 869명의 대상자중 291명(33.4%)이 인터넷 중독 가능성을 가지고 있는 것이고 나타났고 그 중 18명(2.07%)은 명백한 중독경향이 있는 것으로 나타났다. 본 연구에서는 인터넷중독척도 상위 30%를 중독경향군으로, 하위30%를 정상대조군으로 분류하였다. 3) 인터넷 중독척도 평균점수의 비교를 보면 남학생이 여학생보다 통계적으로 유의미하게 점수가 높음을 알 수 있었고 또 남학생이 여학생보다 중독경향군에 포함되는 비율도 더 높음을 알수 있었다. 을, 정상대조군에서는 정보검색을 상대적으로 더 많이 하는 것으로 나타났으며 게임은 두 집단간에 차이가 없었다. 5) 중독경향군에서 더 우울성향이 높고 외부의 부정적 평가에 더 예민하게 반응하고 또래관계의 문제가 많은 것으로 나타났고 사회적 상황에서의 불안정도는 집단간에 차이가 나지 않았다. 결 론 : 인터넷 중독으로 비교적 명백하게 분류된 비율은 이제까지의 다른 연구조사와 비교하여 볼 때 상대적으로 낮게 나왔으나 중독경향군까지 포함했을 겨우, 조사대상자의 약 30%에서 인터넷과 연관된 문제가 있음을 알수 있었다. 또한 인터넷 과다사용으로 문제가 되는 경우에 우울이나 또래관계등의 문제가 더 심각한 것으로 판명되어 향후 인터넷 사용자체에 대한 중독치료적 접근이외에 동반 정신병리에 대한 치료적 접근이 필요할 것으로 생각된다. Objective : The purpose of this study was to survey the present conditions of adolescents' Internet use and to investigate the relation of Internet addiction to depression, social anxiety and problems in peer relationship. Method : Eight hundred and sixty-nine high-school students(male/female=371/498) were included in the study, each of whom completed a standard questionnaire related to Internet use determined. We assessed internet addiction and depressive symptoms of adolescents using Youngs Internet Addiction Scale and the Beck Depression Inventory(BDI), respectively. Social Avoidance and Distress Scale were employed to measure social anxiety and avoidance. Fear of Negative Evaluation-Brief Scale was for fear of negative evaluation by other people. An Index of Peer relation was devoted to problems in peer relationships. Chi-square test and ANOVA were used to identify the present conditions of Internet addiction and to analyze the relations of Internet addiction with depression, social anxiety and problems in peer relationship. Results : 1) Of these 869 subjects, 371(42.7%) were male students and 498(57.3%) were female. The mean age was 16.27 years(SD=0.82) and there was no significant difference between two sex groups. 2) Of these 869 subjects, 291(33.4%) showed addictive tendency and among them 18 subjects(2.07%) were classified into obvious addiction group. In this study, we defined upper 30% of Internet addiction scores as 'addiction group' and lower 30% as 'normal control group'. 3) Male students had significantly higher mean scores of Internet addiction scale than females and there was significantly higher rates of male students in addiction group. 4) Comparing two groups, there was no statistically significant difference in terms of the preferred types of Internet media, although addiction groups tended to use chatting and E-mail more, normal control group tended to use information search more, And there was no significant difference regarding games on the Internet. 5) There was more depressive tendency in line with more sensitive response against negative-evaluation and more problems of peer relationship in addiction group. However, there was no significant difference regarding anxiety on social situation. Conclusion : Compared to previous studies, findings from this study showed that the rates classified as the group of obvious Internet addiction were relatively lower. However, including those who had tendency of Internet addiction, about 30% of all subjects had problems related to Internet use. In addition, depression or relationship problems were triggered more severely in Internet addiction group. With these findings in mind we finally suggest that therapeutic approach to comorbid psychopathology as well as Internet addiction itself should be required.
