PURPOSE: This study was done to build and verify a model of clinical nurses' turnover intention using organizational characteristics, job satisfaction and job embeddedness. METHODS: The study participants were 389 hospital nurses. SPSS and AMOS 22.0 program were used to analyze the data and the modeling of turnover intention. RESULTS: A total of 41% of turnover intention was explained by job satisfaction, job embeddedness and organizational characteristics. Nurses with higher job satisfaction and job embeddedness showed lower turnover intention, while organizational characteristics had an indirect effect on their turnover intention. It was found that organizational characteristics had positive effects on both job satisfaction and job embeddedness, and job embeddedness played a mediating role between organizational characteristics and turnover intention. CONCLUSION: To reduce nurses' turnover intention, hospitals' organizational characteristics should be considered. Nurse managers should strive to increase nurses' job satisfaction and job embeddedness through an understanding of the factors of organizational characteristics such as organizational fairness, nursing work environment, motivation, organizational citizenship behavior, and transformational leadership.

The study was undertaken to evaluate the heat resistance by split dose hyperthermia in various time intervaland temperature. For the experiments, 96 mice were divided into 2 groups: the first, 36 mice were used to evaluatethe skine reaction of mouse tail to single dose hyperathermia, the second, 60 mice were used to evaluate heatresistance by split dose hyperthermia in variuos time intervals. The results obtained are summarized as follows;1. The ND was 101 minutes at 43degrees centigrade(C) and 24 minutes at 45degrees C. 2. For a 1degrees C increasein temperature, a half in time was required to same degree of skin reaction. 3. Heat resistance was significantlydeveloped in split dose hyperthermia at 43degrees C and 45degrees C. 4. Development, maximum and decay of heatresistance were constant regardless of change in temperature. In summary, heat resistance in split dosehyperthermia is important in study and clinical application of heat therapy in malignant disease.

PURPOSE: This study examined Korean clinical nurses' intentions to care for SARS patients and identify determinants of the intentions. Theory of planned behavior was the framework to explain the intentions of Korean nurses for SARS patients care. METHODS: A convenient sample of six hundreds and seventy nine clinical nurses from four university-affiliated hospitals located in Seoul and in Kyung-gi province was used. Self-administered (83-items) questionnaire was used to collect data. Intentions, attitude, subjective norm, perceive behavioral control, behavioral beliefs, normative beliefs, and control beliefs were the study variables. All items were measured using 7-point Likert scale (-3 to +3). Data were analyzed using descriptive statistics, Pearson correlation method, and stepwise multiple regression methods. RESULTS: Intentions and attitudes toward SARS patient care among Korean clinical nurses were moderate, but their subjective norm and perceive behavioral control of SARS patients care were negative. Stepwise multiple regression analysis indicated that attitude toward SARS patient care, perceived behavioral control, subjective norm were the determinants of the intentions for SARS patients care as theory proposed. Among the behavioral beliefs, "SARS-patient caring would be a new experience", "during SARS-patient caring, I should be apart from my family", "after completing SARS-patient caring, I would be proud of myself being able to cope with a stressful event" and "with my SARS-patient caring, patients could recover from SARS" were the significant determinants. Among the normative beliefs, colleague approval, spouse approval, and physician approval were significant determinants of the intentions. Among the control beliefs, "SARS-patient caring would be a challenge" "SARS-patient caring is a professional responsibility", "tension during the care of SARS patients" and "support from team members" were the significant determinants of the intentions. CONCLUSIONS: Korean clinical nurses in this study were not willing to care for SARS patients and showed negative attitude toward the care. They believed their friends and family were not approved their care for SARS patients. Nurses were in conflicts between professional responsibilities to care for SARS patients and personal safety. This study was the first to understand stress and burden of Korean clinical nurses who are in front line to care for newly developed communicable disease such as SARS. Under the circumstance where several fatal communicable diseases are predictable, conflicts between professional responsibility and their personal risks should be taken into considerations by nurses themselves and by nursing administrators in order to improve quality of care.

The determination of the degree and ability of recovery of obstructive hydronephrosis is important in treatment and prediction of prognosis. Among the various methods in determination of the status of kidney, intravenous pyelography is the most important tool to evaluate the morphological and functional changes of kidney in vivo. The purpose of this experiment was the determination of process and recoverability of hydronephrosis depend on duration of unilateral uretreal obstruction. For the experiment, 32 rats were divided into 2 groups; the first group of 12 rats were used to determine the process of hydronephrosis during 1 to 4 weeks of unilateralureteral ligation and the second group of 20 rats were used to determine the recoverability of hydronephrotic kidney depend on same duration of ureteral ligation following relief of ligation. Intravenous pyelography as undertaken and renal angiography, gross and microscopic examination were added. The results obtained are summarized as follows; 1. Kidney enlargement and pelvic dilatation were progressively increased with a relation to duration of ureteral obstruction until 4 weeks. 2. Renal excretory function is not impaired until 3 weeks obstruction, but rapidly impaired to nonfunctioning in 4 weeks obstruction. 3. Renal recovery was possible following relief of ureteral ligation within 3 weeks of ureteral obstruction, but histopathological and functional recovery were impossible in 4 weeks of ureteral ligation. 4. There is no direct correlation between duration of obstruction and recoverability following relief within 3 weeks of uretral obstruction. 5. Intravenous pyelographyis a simple and accurate method to determine the degree of obstructive hydronephrosis and to evaluate morphological and functional recovery of kidney following relief of obstruction.

PURPOSE: The purpose of this study was to determine the differences in the level of disease related knowledge, compliance of health behavior, and educational needs in relation to time (at discharge and 6 months after discharge) among patients underwent percutaneous coronary intervention (PCI). METHODS: Data were collected from January 1, 2006 to September 30, 2006 and a total of 60 patients participated in the study. The survey was conducted in patients underwent PCI at the time of discharge right after discharge education was provided and at a follow up visit which was 6 months after discharge. RESULTS: The level of disease related knowledge (p<.001), the compliance of health behavior (p<.001), educational need (p=.496), the sub-item of sexual life (p<.001), follow up (p<.001), diet (p=.021), stress (p<.001) in compliance of health behavior, and the sub-item of specific character of disease in educational needs (p=.015) were significantly different between discharge and 6 months after discharge. CONCLUSION: The results of this study suggested that further education should be provided to the patients underwent PCI regarding medication, smoking cessation, daily life and exercise at a time of 6 months after discharge in order to increase patient compliance of health behavior.

The purpose of this study was to explore the effect of diabetic camp program on depression, self-efficacy and self-esteem of the juvenile diabetic patient who had participated with diabetic camp program at Seoul and Kyung In area from August 5 to August 9, 1995. Nursing staffs explained them how to respond to the questionnaire of depression. self-efficacy and self-esteem prior to beginning the program and following the program. The questionnaire of depression, self-efficacy and self-esteem was developed by both diabetes mellitus nurse specialist and pediatric nursing professors in reference with the previous research. Response items of the questions were structured as yes or no for the elementary school students and that of the questions were structured as 5 likert scale for the both middle and high school students. Paired t-test was used for the significance of the difference between values before and after the diabetic camp program. Depression decreased following the program, while self-esteem increased significantly following the program in elementary school students. There was no change in self-esteem, while self-efficacy increased significantly following the program in middle and high school students. Self-efficacy following the program was high as the frequency of exercise increased in the elementary school students. Self-efficacy prior to the program was high as the experience of diabetic education increased in the middle and high school students. Self-efficacy and self-esteem prior to the camp was highly correlated with that following the camp in middle and high school students. The result suggests that diabetic camp program could be on of ways to decrease depression and to increase self-efficacy of the diabetic children.

The use of autologous fat grafts has questionable clinical value due to unreliable grafts survival. For the purpose of improved graft survival, re-implantation of cryopreserved adipocytes is developed. The purpose of study is to analyze the changes of freeze-preserved adipocytes and to find out efficient long-term storage period. After centrifugation of aspirated abdominal tissues, 10ml of packed adipocytes were freezed at -20 degrees C (n=70). For 6 months, each 10 frozen samples were taken and analyzed at 1 month interval. Significant volume changes were observed in cryopreservation for 3 months (p < 0.05). The profiles of total lipid and FFA were not changed and no significant difference in saturated fatty acid ratio with gas chromatography. No histologic changes were observed, independent of the freezing period with H & E stain. The reduction of mitochondrial enzymatic activity was observed independent of time interval but activity of mitochondrial dehydrogenase was reduced less than 50% in XTT assay. On the basis of these data, -20 degrees C freezing for 6 months has no adverse effect to adipocytes, but frigile adipocytes, damaged cell membrane during harvest procedure, were disrupted within 1month and the maximum volume reduction were followed less than 3 months. These results demonstrate that tissue preparation cells with no cell membrane damage have the greatest viability level and cryopreservation less than 3 months has great volume effect.

The estrogen receptor (ER) is present in a wide variety of mammalian tissues and is required for the physiological responses of estrogen, including estrogen-induced tissue-specific changes in gene expression. But most of our knowledge on the regulation of ER mRNA levels comes from in vivo steroid replacement experiments or cancer cell lines that express the ER. Thus the present study was attempted to determine 1) the anterior pituitary ER mRNA levels during rat estrous cycle 2) if estradiol itself directly modulates the ER mRNA levels in cultured rat anterior pituitary using RT-PCR method. In rats with 4 day estrous cycle, the ER mRNA levels in anterior pituitary gland reached to maximum at proestrus 11:00h just before serum estradiol concentration showed the highest. From then, the ER mRNA levels gradually declined during the rest of the proestrus. On the other hands, in cultured rat anterior pituitary cells, the ER mRNA levels were significantly decreased by the treatment of estradiol. These results indicate that the surge of estradiol was proceeded by the increase in pituitary ER mRNA levels during the proestrus and in cultured anterior pituitary cells, estrogen might be involved in the down-regulation of the ER mRNA levels.
