본 연구는 우리나라에서 재배한 삼채 추출물의 주요생리활성 물질을 2형 당뇨 쥐에 투여하였을 때 인슐린 저항성 개선효과와 췌장에서 β-cell의 형태 및 간 조직의 2형 당뇨 관련 단백질의 발현을 확인 함으로써 그 메카니즘을 확인코자 하였다. 특히 TZDS당뇨약 계열로 현재 시판중인 actoz와 활성을 비교 함으로써 그 유효성 정도를 살펴보고자 본 실험을 디자인하였다. 먼저 식이섭취량, 물 섭취량의 경우, Control군은 2형 당뇨 특징인 다식, 다뇨, 다갈의 형태로 증가하였으나, 삼채 추출물 투여로 식이 및 물 섭취량이 감소하는 경향을 보였다. 식이 투여 2시간 후 혈당변화와 OGTT 검사결과, 2형 당뇨인 Control군에서 혈당의 농도가 가장 높았으나 삼채 추출물 8주 경구투여로 인해 안정화되는 것을 확인할 수 있었으며, serum의 glucose농도 또한 삼채 추출물 투여로 2형당뇨 control군에 비해 혈당이 감소한 것을 확인할 수 있었다. HbA1c (당화혈색소)는 2형 당뇨군(control)에서 9% 수치 범위로 고혈당 범위였으나, 삼채 추출물 섭취로 인하여 Positive control군(actoz 투여군) 7% 수준으로 감소하는 경향을 확인할 수 있었으며, insulin농도는 2형 당뇨인 Control군에서 insulin 농도가 1 ng/ml로 가장 낮은 농도였으며, 삼채 추출물 및 SAC 1.5 ng/ml수준으로 insulin수치가 상승하는 것을 확인할 수 있었다. 혈중 triglyceride, total cholesterol 및 LDL-cholesterol 수치 모두 시료 투여군에서 혈중 지질관련 인자의 농도가 감소하는 것을 확인할 수 있었으며, 특히 AH 400군의 경우 triglyceride, total cholesterol 및 LDL-cholesterol 농도가 각각 482.86±13.40 mg/dl, 163.56±13.24 mg/dl, 142.04±3.24 mg/dl로 대조군에 비해 약 50% 감소한 결과를 나타내었다. 간장 조직 중 지질 과산화의 함량의 경우, 2형 당뇨인 Control군에서 467.74±1.12 MDA nmole/g of tissue로 삼채 추출물 투여(AH 400)로 319.61±26.98 MDA nmole/g of tissue 로 Normal군과 비슷한 수준으로 혈중 lipid peroxide의 함량이 감소하는 것을 확인할 수 있었다. 간장조직을 H&E염색한 결과, Normal군에 비하여 2형 당뇨인 Control군의 간 조직에서 많은 지방적이 나타나 지방간이 확인되었으나, Positive control 및 삼채 추출물 투여에 의해 지방적의 크기와 수가 많이 줄어드는 결과를 얻어 조직학적 검사상 지방간의 소견이 현저히 호전되었으며, 췌장에서 insulin 면역화학 염색 결과 2형 당뇨로 췌도 세포가 거의 손상된 것과는 대조적으로, 삼채 추출물을 투여한 결과 정상군과 유사한 형태의 췌도 세포가 확인되었으며 췌도 세포의 형태가 다양한 정도의 과 형성을 보이는 것이 확인되었다. 또한 간장 조직의 PPARγ, PDK4, SREBP-1, FOX0 1의 발현을 확인한 결과, 발현이 2형 당뇨인 Control군에서 모두 발현이 증가하였으나, 삼채 추출물 투여로 인해 발현 정도가 낮게 나타나 앞서 확인하였던 glucose 및 HbA1c 및 insulin농도의 결과와 상통함을 확인하였다. 이들의 결과로 미루어 볼 때, 삼채 메탄올 추출물의 8주간 경구 투여로 인하여 2형 당뇨에 관여하는 PPARγ 단백질 및 비만 관련 단백질 인자를 조절하였으며, insulin농도 및 식후 혈당조절에도 도움을 주는 것을 확인할 수 있었다. 또한, 췌장의 insulin 면역화학염색 결과, 췌도 세포 형태 및 insulin 합성에도 긍정적인 역할을 하는 것으로 미루어 보아 2형 당뇨에 대한 치료효과가 큰 것으로 사료 된다.

본 연구는 부추의 안전한 재배를 위해 전국에 부추를 재배하는 지역 중 겨울재배지 A지역 3농가(I, II, III)와 여름재배지 B지역 3농가(I, II, III)를 선정하여 부추와 부추가 재배되고 있는 토양의 미생물 오염도를 조사하였다. 부추와 부추 재배 토양에서 위생지표세균(일반세균수, 대장균군, 대장균)과 병원성 미생물(B. cereus, E. coli O157:H7, Salmonella spp., L. monocytogenes)을 조사하였다. 그 결과, A지역 3농가의 부추에서 일반세균수는 5.87-8.76 log CFU/g으로 검출되었으며 r대장균군은 1.20-6.98 log CFU/g으로 검출되었다. B지역 3농가에서는 일반세균수가 6.30-7.90 log CFU/g으로 나타났으며 대장균군은 4.97-7.36 log CFU/g이었다. 또한 A지역 3농가의 부추 재배 토양에서 일반세균수는 5.94-7.48 log CFU/g으로 검출되었으며 대장균군은 2.45-5.62 log CFU/g으로 검출되었다. B지역 3농가에서는 일반세균수가 6.30-7.80 log CFU/g으로 나타났으며 대장균군은 6.17-7.40 log CFU/g으로 검출되었다. A지역과 B지역의 부추, 부추 재배 토양에서 대장균이 모두 검출되지 않았다. 두 지역의 부추와 부추 재배 토양의 병원성 미생물 분석 결과, B. cereus는 A지역의 부추 시료 30개 중 8개(26.6%) 시료에서 검출되었으며 부추 재배 토양 24개 시료 중 24개(100%) 시료에서 검출되었다. 또한 B지역 3농가는 모두 멀칭한 농가로 부추에서는 B. cereus가 검출되지 않았으며 부추 재배 토양에서 9개 시료 중 6개(66.6%) 시료에서 검출되었다. 반면에 두 지역의 부추와 부추 재배 토양에서 E. coli O157:H7, Salmonella spp., L. monocytogenes은 검출되지 않았다. 농산물에서 B. cereus와 같은 병원성 미생물의 오염은 재배단계에서 토양 등으로 인해 쉽게 오염될 수 있다. 이러한 오염을 줄이기 위해 농작물 재배 시 작물과 토양의 접촉을 최소화하기 위해 토양 멀칭재배와 온도 및 습도 등 재배환경을 관리하는 것이 미생물 오염도를 줄이는데 효과적일 것으로 판단된다. 또한 농산물로 인한 식중독 사고를 예방하기 위해서는 재배환경 모니터링 연구와 위생적인 관리방안에 대한 지속적인 연구가 필요할 것이라고 생각된다.

Korean labor market has showed remarkable change of the increase in the amount of unemployment and contingent employment since IMF bailout agreement. There is a theoretical position to explain this increase in contingent employment at hospitals with the notion of flexibility. The high flexibility of employment due to the increase of contingent employees is becoming very important part in new business strategy of hospitals. The types of contingent employment of the nurse are part-time employment temporary employment, fixed-term employment, and internship which was introduced in early 1999. Recently, Korean health care industry managers have paid attention to the customer oriented service, rationalization of business administration, service quality control so that they can adjust their business to outer environment. Especially their efforts concentrate on the wage reduction through efficient and scientific control of man power because wage shares about 40% of total cost. This dissertation aims at verifying the phenomena of the contingent employment of the nurse and analyzing the related factors and problems. To rephrase these aims in ordinal: First, verifying the phenomena of contingent employment of the nurse. Second, verifying the problems of that phenomena. Third, analyzing the related factors of the contingent employment of the nurse. To accomplish these research goals, a statistical survey was executed. in which 384 questionnaires-66 for manager nurses, 318 for contingent nurses - were given to nurses working at 66 hospitals-which have at least 100 beds-in Seoul. Among them, 187 questionnaires-38 from manager nurses, 149 from contingent nurses'- 'were returned. Then, the data coded and submitted to T-test, $X^2$ -test, variance analysis(ANOVA), correlation analysis, multiple regression analysis, Logistic Regression with SAS program. The research results of the contingent nurses are followings: 1. The average career term at the present hospital 8.4 months: duty-on days per month are 24.2 days: working time per day is 7.9 hours. These results showed little difference from regular nurses. 2. Their wage level is about 70% of regular nurses except for internship nurses whose wage level is 41% of regular nurses. To break down the wage composition, part-time nurses and internship nurses get few allowance and bonus. And contingent nurses get very low level of additional pay except for fixed-term nurses who are under similar condition of employment to regular nurses. These results show that hospital managers are trying to reduce the labor cost not only through the direct way of wage reduction but through differential treatment of bonus, retirement allowance, and other additional pay. 3. The problem of contingent employment: low level of pay; high level of turn-over rate: weakening of union; low level of working condition: heavy burden of work; inhuman treatment. The contingent nurses consider these problems more seriously than manager nurses do. What manager nurses regard problematic is the absence of feeling-belonged and responsibility of the contingent nurses. 4. The factors strongly related with the rate of the number of contingent nurses for the number of regular nurses; gross turn-over nurses; average in-patients per day; staring wage of graduate from professional college: the type of hospital ownership; the number of beds; the gap between gross newcomer nurses and gross turn-over nurses. The factors related with their gross wage per month; the number of beds; applying of health insurance; applying of industrial casualty insurance; applying of yearly-paid leave; the type of hospital ownership; average out-patients per day; gross turn-over nurses. The meaningful factors which make difference by employment type: monthly-paid leave; physiological leave. The logistic regression analysis using these two factors shows that monthly-paid leave is related with the type of hospital ownership; the number of beds; average out-patient per day, and physiological leave is related with the gross newcomer nurses; gross turn-over nurses; the number of beds.

The major objective of this research is to identify those hospital characteristics that best explain cost variation among hospitals and to formulate linear models that can predict hospital costs. Specific emphasis is placed on hospital output, that is, the identification of diagnosis related patient groups (DRGs) which are medically meaningful and demonstrate similar patterns of hospital resource consumption. A casemix index is developed based on the DRGs identified. Considering the common problems encountered in previous hospital cost research, the following study requirements are estab-lished for fulfilling the objectives of this research: 1. Selection of hospitals that exercise similar medical and fiscal practices. 2. Identification of an appropriate data collection mechanism in which demographic and medical characteristics of individual patients as well as accurate and comparable cost information can be derived. 3. Development of a patient classification system in which all the patients treated in hospitals are able to be split into mutually exclusive categories with consistent and stable patterns of resource consumption. 4. Development of a cost finding mechanism through which patient groups' costs can be made comparable across hospitals. A data set of Medicare patients prepared by the Social Security Administration was selected for the study analysis. The data set contained 27,229 record abstracts of Medicare patients discharged from all but one short-term general hospital in Connecticut during the period from January 1, 1971, to December 31, 1972. Each record abstract contained demographic and diagnostic information, as well as charges for specific medical services received. The 'AUT-OGRP System' was used to generate 198 DRGs in which the entire range of Medicare patients were split into mutually exclusive categories, each of which shows a consistent and stable pattern of resource consumption. The 'Departmental Method' was used to generate cost information for the groups of Medicare patients that would be comparable across hospitals. To fulfill the study objectives, an extensive analysis was conducted in the following areas: 1. Analysis of DRGs: in which the level of resource use of each DRG was determined, the length of stay or death rate of each DRG in relation to resource use was characterized, and underlying patterns of the relationships among DRG costs were explained. 2. Exploration of resource use profiles of hospitals; in which the magnitude of differences in the resource uses or death rates incurred in the treatment of Medicare patients among the study hospitals was explored. 3. Casemix analysis; in which four types of casemix-related indices were generated, and the significance of these indices in the explanation of hospital costs was examined. 4. Formulation of linear models to predict hospital costs of Medicare patients; in which nine independent variables (i. e., casemix index, hospital size, complexity of service, teaching activity, location, casemix-adjusted death. rate index, occupancy rate, and casemix-adjusted length of stay index) were used for determining factors in hospital costs. Results from the study analysis indicated that: 1. The system of 198 DRGs for Medicare patient classification was demonstrated not only as a strong tool for determining the pattern of hospital resource utilization of Medicare patients, but also for categorizing patients by their severity of illness. 2. The wei틴fed mean total case cost (TOTC) of the study hospitals for Medicare patients during the study years was $11,27.02 with a standard deviation of $117.20. The hospital with the highest average TOTC ($1538.15) was 2.08 times more expensive than the hospital with the lowest average TOTC ($743.45). The weighted mean per diem total cost (DTOC) of the study hospitals for Medicare patients during the sutdy years was $107.98 with a standard deviation of $15.18. The hospital with the highest average DTOC ($147.23) was 1.87 times more expensive than the hospital with the lowest average DTOC ($78.49). 3. The linear models for each of the six types of hospital costs were formulated using the casemix index and the eight other hospital variables as the determinants. These models explained variance to the extent of 68.7 percent of total case cost (TOTC), 63.5 percent of room and board cost (RMC), 66.2 percent of total ancillary service cost (TANC), 66.3 percent of per diem total cost (DTOC), 56.9 percent of per diem room and board cost (DRMC), and 65.5 percent of per diem ancillary service cost (DTANC). The casemix index alone explained approximately one half of interhospital cost variation: 59.1 percent for TOTC and 44.3 percent for DTOC. Thsee results demonstrate that the casemix index is the most importand determinant of interhospital cost variation Future research and policy implications in regard to the results of this study is envisioned in the following three areas: 1. Utilization of casemix related indices in the Medicare data systems. 2. Refinement of data for hospital cost evaluation. 3. Development of a system for reimbursement and cost control in hospitals.

Reumatic arthritis is a disease with joint pain being one of the key symptoms. The patient suffers from the pain, stiff sensation and edema due to the inflammation taking Place In one or more joints. Accompanying these problems are fatigue, unusual exhaustion, fever, tachycardia and weakness. Inaddition, joints are often deformed and muscles shrink along with the progress of edema, coupled with depression and psychological instability resulting from the loss of the mobile function and limitations on the daily life. Some patients become fed up with the long and hard flight with the disease and just give up, which aggravates the symptoms. Others come to the hospital only when the conditions have become serious. We need to prevent these and guide the patients in the right direction. Against this backdrop, this study aims to look into the relations between the knowledge on the part of the patients together with their feeling of self-efficacy and the compliance. The results are expected to help the patients improve their life, In addition to providing useful materials for setting up appropriate plan for nursing intervention. The study was conducted by distributing questionnaire to 88 patients selected from the out-patient department of a university hospital in Inchon, from April 6 to 27, 1998. The following tools were used the yardstick of self-efficacy, developed in 1997 by the Society for the Health of Rheumatism Patients, was used for measuring the levels of knowledge and the feeling of self-efficacy. The degree of compliance was measured by the data collected from documents in addition to the results of the analysis of the interviews with the patients. The reliability of the tools was confirmed. In the analysis, the general characteristics were expressed in figures and percentages. The levels of knowledge, feeling of self-efficacy, and compliance were expressed in the average values and standard deviations. The relations among the variables following the general characteristics were analysed by the t-test and one-way ANOVA. The Pearson correction coefficient was used for the analysis of factors. Multiple-loop analysis was used to identify the variables affecting the compliance. The following are the results of this study. 1. Among the 88 patients, 18 were men and the remaining 70 were women, with a ratio 1 : 3.87. Regarding the age groups, 23 were between 50 and 59 years old, with those between 50 and 69 accounting for 51.1% of the total. High school graduates or higher amounted to 58%. Religious patients was 67% or 59 persons. Fifty nine percent were unemployed, and 58.3% (49 persons) had two children or fewer. The period of suffering from rheumatism varied between 2 months and IS years, with 70% less than years. 2. The average figure In relation to the of knowledge was 17.63 points over 30 or 58. 76%, which means a medium level. 3. The average figure of the feeling of self-efficacy was 60.06 points. 4. The level of compliance was 3.26, which was above average. 5. The relation between the feeling of self-efficacy and compliance showed an "r" value of 0.37, which was significant. It means that the higher the feeling, the greater the compliance points. 6. The analysis of the knowledge level revealed that the difference is found only between the college graduates and junior-high graduates or lower. 7. The feeling of self-efficacy varied along with the age and education level. 8. The general characteristics of patients as discussed above did not show significant difference with the compliance. 9. Regarding the elements influencing the compliance, the number of children, period of suffering, income, age, feering of self-efficacy, knowledge, and compliance had 54% of significance. In conclusion, rheumatism victims can lead a better life if they are appropriately educated, based on efficient training program from the early days of the disease ; if they become able to manage themselves thanks to the training ; and if they are helped by a program focusing on the increase of the feeling of self-efficacy aimed at changing patient's behavior.

청틸라피아(Oreochromis aureus)의 자어에 0, 1, 10, 60 ppm의 $17\alpha-Methyltestosterone$ (MT)을 30 일간 성 전환기 사료에 섞어 먹인 후 다음 39 일간(성전환 후기) 0 ppm 을 먹인 그룹은 다시 세 그룹으로 나누어 0 ppm MT (0-0), 10 ppm MT (0-10), 및 60 ppm MT (0-60)을 먹였고, 60 ppm을 먹인 그룹은 다시 3 그룹으로 나누어 0 ppm MT (60-0), 10 ppm MT (60-10), 및 60 ppm MT (60-60)을 먹였으며, 초기 30 일간 1 ppm과 10 ppm MT를 먹인 것은 계속해서 각각 1 ppm과 10ppm을 먹여서 월동시킨 다음 10개월 후인 이듬해 9월 말경에 체조성과 생식소 중량 지수에 미치는 영향을 조사하였다. 암수 모두에서 2 년째의 성장에 대한 MT의 잔류 효과는 없었다. MT를 먹인 그룹의 성장은 전혀 먹이지 않은 대조군보다 통계적으로 유의성있게 좋았는데(P<0.05) 그 이유는 대조군에 있는 암컷의 성장 지연으로 인한 전체 평균 중량의 감소 때문이었다 사료 중의 MT 함량이 증가하는데 따라 수컷의 조지방 함량은 증가하여 순상관 관계의 잔류 효과를 나타내었으나 체 수분 함량은 오히려 MT가 증가함에 따라 감소하는 역상관 관계의 결과가 나타났다. 암컷에서는 사료 중 MT가 증가함에 따라 체 수분함량이 감소하는 역상관 관계의 잔류 효과를 보였다. 성전환 후기의 암수 모두의 생식소 중량 지수에 역상관 관계를 나타내었고, 성전환기에 사료에 섞어 섭취된 MT는 2 년째의 수컷의 생식소 중량 지수에 잔류 효과를 나타내어 MT 농도가 증가하는데 따라 생식소 중량 지수가 감소하는 역상관 관계를 나타내었다. .그러나 생식소 발달이 완료된 성전환 후기에 먹인 MT는 암수 모두에서 생식소 중량 지수에 잔류 영향을 보이지 않았다.

This research is aimed to define how the depression, performing ability of IADL and muscular-skeletal pain of the Aged, according to their residential circumstance, sex and age, can affect the subjective health index and how all these are related and associated with. For the period of June 1 to July 31, 2000, in order to study and define how the depression, performing ability of IADL and muscular-skeletal pain are related to the subjective health index of the Aged, we have conducted an enquete through a direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent areas, divided into three different residential types “The Aged living at home”, “The Aged living at welfare facilities” and “The Aged living alone”. We have studied all the data and information obtained through this enquete and have analyzed χ²-test, t-test, ANOVA, analysis of simple correlation, analysis of factor. by SPSS10.0/PC+. The results were as follows: Generally, the four (4) factors depression, IADL performing ability, muscular-skeletal pain and the subjective health index of the Aged, are a lot influenced by and related to their residential circumstance, their sex and their age. With regard to the depression of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 48.3 point which reflects comparatively the higher points and the female-Aged is more depressed. In analyzing depression of the Aged by their age, it appears that the Aged between eighty (80) to eight-four (84) years of age, gains 49.2 point which is the highest points and simultaneously we could realize that depression follows age, - the more the age gets, the more the depression is increased. In analyzing depression of the Aged by their residential type, it shows that “the Aged living alone” gains 50.9 point and is most depressed. With regard to the IADL performance of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 23.8 point, which shows the performance of the female-Aged is less independent. In addition, it was also found that the IADL performing ability is becoming less and less independent following their age increasing. In analyzing IADL performance by their residential type, it appears that “the Aged living at welfare facilities” gains the lowest 21.5 point and is least independent. We conclude that some assistances from others are required for the Aged living at welfare facilities in their performing IADL. With regard to the muscular-skeletal pain of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 3.0 point and the female-Aged suffers from this pain more severely. In analyzing this pain by their residential type, it was found that, on an average, the 3.0 point goes for “the Aged living alone”, which explains the Aged living alone is having the most serious pain. With regard to the subjective heath index of the all Aged participated in this research, the analysis indicates 8.8 point and this is considered as a general standard (7-10 point). In analyzing this index by their sex, the female-Aged gains 8.6 point only and it explains a lot of female-Aged consider they are not really healthy. In analyzing this index by their residential type, “the Aged living at welfare facilities” and “the Aged living alone” gain the comparatively lower point, -respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged of these two residential types express they are obviously in a bad condition of health, which makes us think a lot. With regard to the factors affecting the subjective health index of the Aged, it was analyzed that this index can significantly be influenced by their depression, their pain, their age and by how much they are satisfied with their current living conditions, and also analyzed that the correlative relation certainly exists between the depression and pain, and the subjective health index, - that is, the more the depression and pain are serious, the lower the subjective health index indicates. As for the IADL, it appears that the IADL's relation with this index is not that significant and even not important.
