This study is to identify the effect of using admixture and polypropylene fiber on the quality of concrete. The results of the changes in the quality of concrete that has not yet hardened and concrete that has hardened is as follows: 1. Depending on the proportions of admixture, the greater the fly ash content and the lower slag and silica fume, the greater the slump. Admixture and polypropylene together contributed to increased slump. 2. The more fly ash, slag and silica fume added, the less the air. 3. After 360 days of age, greater fly ash content contributed to a lower compressive strength, while greater slag added to higher compressive strength. Silica fume shows a high compressive strength when 10% of silica fume was added on the 360th day of age. 4. Tensile Strength at 360 days of age, the less fly ash and the more slag, the higher the tensile strength. Silica fume at 360 days of age increase strength when the mixing proportion was 30%. 5. The more fly ash and the less slag and silica fume that were mixed, the greater the fire resistance. When added to and polypropylene fiber, the fire resistance of concrete of no effect. 6. The more fly ash and silica fume, the more carbonation shown and when there was only 10% slag present, the neutralization was also shown.

In order to investigate the characteristics of job transfer and job satisfaction of general hospital nurses and provide the nurse department the basic materials neccesary for efficient manpower management, 400 nurses were selected from two university hospital in chunan Choognam. The study subject was nurses who came from special nursing care unit such as intensive care unit and emergency room and general nursing care unit such as general surgery ward, orthopedic surgery ward and neurosurgery ward. The priod of this study was from February 2 to 28, 1998. The results of the study were as follows. 1. While 252 nurses(63.0%) had transfer experience, 148 nurses(37.0%) didn't have. Two hundred sixty five nurses(67.7%) wanted over 15 days for the preparation period before job transfer and 57.7% wished the periodical change of assignment and 19.5% wanted job transfer in present nursing unit. 2. While the cause of wanting job transfer were "defict of accomplishment and worth in job(84.6%)", "to acquire experience of other nursing unit(83.3%)", "unsuitableness of own's aptitude in job(73.1%)" respectively, the cause of unwanting job tranfer were "possibility of transfer to undesired nursing unit(87.9%)", "satisfaction of present nursing unit(84.8%)", "anxiety of new nursing unit(73.0%)" respectively. 3. The mean score of opinion of job transfer effect was 3.1. Among these opinions the mean scores of professional development, employee' common desire, and management were 3.3, 3.0, and 3.0 respectively. 4. The mean score of opinion of job satisfaction was 3.0. Among these opinions the mean scores of interaction, professional status, autonomy, and task requirements revealed to be high, and were 3.6, 3.6, 3.1 and 3.0, respectively, and those of pay, administration, and doctor-nurse relationship showed to be low, and were 2.7, 2.7, and 2.5, respectively. 5. According to position. work duration. nursing unit, there were statistical difference among job satisfaction such as pay, professional status, doctor-nurse relationship, administration, autonomy, task requirements, and interaction. 6. The spearman correlation coefficients of professional development category on the effect of job transfer with job satisfaction were administration (rs=0.159, p=0.0014), autonomy(rs=0.142, p=0.0043), and task requirement(rs=0.139, p=0.053), respectively, The spearman correlation coefficients of administration-management category on the efffect of job transfer with job satisfaction were administration(rs=0.276, p=0.0001), autonomy(rs=0.246, p=0.0001), and task requirement(rs=0.236, p=0.0001), respectively. the spearman correlation coefficients of employee' common disire category on the effect of job transfer with job satisfaction were autonomy(rs=0.243, p=0.0001), administration(rs=0.227, p=0.0001), and task requirement(rs=0.213, p=0.0001), respectively.

Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. One routine chest film of a patient who was checked and hepatoma-diagnosed in Internal Medicine, Chosun University Hospital left the room for doubt of mediastinal mass. But no subjective symptoms for the mass was told by the patient. This is to report our experience of a patient having right side aortic arch with aberrant left subclavian artery, as proved by diagnosis, but none of congenital heart disease. This right side aortic arch with aberrant left subclavian artery is the most frequent type among right aortic arch, the anomaly of which is usually detected from the incidental suspicion for mediastinal mass at routine chest film; because no symptoms are accompanied therewith.

연구목적: 본 연구는 Y공단의 제조공정에서 저농도의 유기용제(solvent)에 장기간 노출된 근로자의 정신의학적 기능과 삶의 질을 평가하고자 하였다. 방법: 총 142명의 남성근로자 중 유기용제에 폭로된 군(이하 폭로군) 82명과 폭로되지 않는 군(이하 비폭로군) 60명에게 간이정신진단검사(Symptom Checklist-90-R, SCL-90-R), 인지 및 정신운동성검사 (Critical Flicker Fusion Threshold. CFFT; Choice Reaction Time, CRT;Compensatory Tracking Task, CTT;Digit-Symbol Substitution, DDS) 및 한국판 스미스클라인 비챰 삶의 질 척도(Korean version of the SmithKline Beecham 'Quality of Life' Scale, KvSBQOL) 등을 적용하였다. 두 군간의 비교는 평가치의 평균에 대해 t-검증을 하였고 또한 연령과 학력을 공변인으로한 공변량분석(ANCOVA)을 하였다. 결과: SCL-90-R의 9개 증상 차원과 3개 전체 지표 점수는 두 군이 각각 정상범위였다. 그러나 신체화 (Somatization, SOM), 우울(Depression, DEP), 적대감(Hostility, HOS), 공포불안(Phobic anx-iety, PHOB)의 증상차원과 전체심도지수(Global Severity Index, GSI), 표출증상합계(Positive Symptom Total, PST)의 전체 지표는 폭로군이 비폭로군보다 유의하게 높았다. 인지 및 정신운동성 검사와 삶의 질은 두 군간에 유의한 차이는 없었다. 결론: 이상의 결과는 유기용제가 허용치 이하일지라도 장기간 폭로되는 경우에는 정신의학적 문제를 다소 일으킬 수 있음을 시사하였다. 중심단어:유기용제·근로자·정신건강·정신운동성 기능·삶의 질. Objectives: The aim of this study was to evaluate the psychiatric function and quality of life of the chemical workers who had been exposed to long-term, low-level organic solvents in the Y industrial complex. Method: A total of 144 male workers, of whom 82 were in the exposed group and 60 in the unexposed-control group, were evaluated by using Symptom Checklist-90-R(SCL-90-R), series of neuropsychological tests(critical flicker fusion threshold, CFFT) ; choice reaction time, CRT ; compensatory tracking task, CTT) ; digit symbol substitution test, DSS), and the Korean version of the SmithKline Beecham Quality Of Life scale(KvSBQOL). For the statistical analyses, comparisons of the means of the two groups were performed for each variable with two-tailed t-test as well as ANCOVA including age and education as covariates. Results: For the SCL-90-R, the nine symptom scales and the three global indices were clinically within normal range in both groups. However, the scores on the symptom scales of 'somatization','depression','hostility' and 'phobic anxiety', and those on the global indices of 'global severity index' and 'positive symptom total', were significantly higher in the exposed group than in the unexposed group. In terms of the neuropsychological function and the quality of life, there wes no significant difference between the two groups. Conclusion: These findings suggested that the long-term eposure to mixed organic solvents, even at the low level below the permissible exposure limit, might induce some psychiatric problems. KEY WORDS: Organic solvent·Worker·Mental health·Psychomotor function·Quality of life.

Recently HIV infection has been increasing in Korea and recognized as one of the serious social problems. In the current situation in which any effective treatment or preventive vaccine for AIDS has not yet been invented, the most important method of control to reduce the chances of HIV infection is through the continuous education about AIDS. Hospital workers are one type of group which are at a high risk for HIV infection and to some degree resposible for the transmission of AIDS. This study was carried out to provide data to help educate hospital workers prevent the AIDS transmission. For this study, 409 workers from 18 hospitals in the Seoul area were asked to answer the questionaire. The results obtained are as follows : 1. Most respondents (97.8%) knew that AIDS is Acquired Immune Deficiency Syndrome. And 85.6% of respondents knew exactly (71.4%) or roughly (14.2%) about the general characteristics of AIDS. 2 . 68.6% of the respondents knew the route of HIV infection. A lot of people thought that one could be infected by AIDS through utensils, foods, coughing or sneezing. 3. Respondents with high education knew relatively well about the causes of AIDS, compared with those with low education. Males generally understood the characteristics about AIDS better than females. As for the age group, the people in their thirties knew more than those in any other age group. Whereas average income amount, marrige status, or overseas travel experience showed no correlationship with the knowledge about AIDS. 4 . It was observed that males(36.5%) had more experience wity blood donation than females (8.8%) . 83.8% of females thought that they need not take the blood test to be examined for HIV infection, which was higher compared to the 62.3% of males. 5. Mass communication was the main source to provide the information about AIDS for the respondents. Most of the respondents hoped that the hospital where they worked or any other clinic would provide them with more detailed information about AIDS. 92.8% of the respondents insisted that AIDS patients should be isolated to prevent the AIDS transmission.
