PURPOSE: The purposes of this study were to understand the general hospital nurses' work stress, burn out and turnover intention and to identify the factors that influence on turnover intention. METHODS: This study was conducted through a survey of 283 nurses having at least 6 months of work experience of 4 general hospitals in Seoul. Data were collected from September to October 2009. The data were analyzed using descriptive statistics, ANOVA, and stepwise multiple regression test with SPSS WIN 14.0. RESULTS: The score for turnover intention was 3.57 out of 5. Turnover intention was significantly correlated with work stress, burn out, and working position. The factors influencing turnover intention were organizational system, depersonalization, physical environment, work position, and occupational climate. The predict variables accounted for 27.9% of turnover intention. CONCLUSION: The results of this study show that factors influencing turnover intention are organizational system, depersonalization, physical environment, work position, and organizational climate. Therefore, nursing managers should understand the organization's climate and establish a reasonable organization system to decrease turnover intention.

The early postpartum period is crucial toward in recovery form childbirth and attainment of the maternal role. Maternal role attainment is a complex social and cognitive process of stimulus-response accomplished by learning. Helping for maternal role attainment is one of nursing goals in the early postpartum period. Based on King's conceptual framework for nursing, this study was planned as descriptive correlation study to determine the significant differences of the degree of nursery room nurses' role performance according to several variables of personal, interpersonal, and working system of nurses in nursery room, The purpose of this study was to contribute to the planning of nursing care to help maternal role attainment of the early postpartum period of mothers and to the development of relevant nursing theory, The data were collected from R3b. 3 to 28 by questionnaires with 273 nurses in nursery room. The instruments for this study were consisted of four parts: 21 questions for roll performance of nurse ; 37 questions for personal system of nurse including 31 questions for role perception of nurse ; 65 questions for interpersonal system including 63 questions for job stress of nurse ; 18 questions for working system of nurse. The toes to measure role performance and role perception, and job stress of nurse were tested for internal reliability. Cronbach's Alphas were 0.9612, 0.9058, and 0.9649. The data were analysed by using in S.A.S. computerized program and included percentage, t-test, ANOVA, Pearson Correlation Coefficient, and Duncan multiple range test. The conclusions obtained from this study are summarized as follows : 1. The mean score of the items of role performance was 2.12(SD=0.55) in Likert's 4 points scale. 2. The degree of role performance was significantly different according to role perception(p=0.0001), age(p=0.006), educational background(p=0.002), and certificate of midwife(p=0.03) among variables of personal system of subjects. 3. The degree of role performance was significantly different according to job stress(p=0.0001) and numbers of children(p=0.006) among variables of interpersonal system of subjects. 4. The degree of role performance was significantly different according to having opportunities for baby(p=0.03), the degree of flexibility to bring baby to mother's room(p=0.046), the scope of visitor for baby(p=0.016), the degree of flexibility of visiting for baby(p=0.049), the degree of participation of nurse in establishing visiting rules(p=0.017), existence and/or nonexistence of rules for breast feeding(p=0.010), existence and/or nonexistence of education for breast feeding(p=0.009), existence and/or nonexistence of breast feeding room(p=0.013), concret methods for breast feeding(p=0.003), working place(p=0.0001), and career(p=0.019) among variables of personal system of subjects.

BACKGROUND: Vasoconstrictors have been used as an adjunct to local anesthetics to prolong the duration of spinal anesthesia. Recently, clonidine, an 2-receptor agonist has been shown to prolong the duration of spinal anesthesia following intrathecal administration. Bupivacaine has been used for spinal anesthesia and compared with tetracaine in recent studies. We have undertaken this study to further evaluate the effect of clonidine in hyperbaric 0.5% bupivacaine spinal anesthesia. METHODS: Thirty patients who were scheduled for lower limb or urologic operation were divided into 2 groups: Group A (hyperbaric bupivacaine 13 mg, 2.6 ml + N/S 1 ml), Group B (hyperbaric bupivacaine 13 mg, 2.6 ml + clonidine 150 g, 1 ml). We used standardized techniques and injected above drugs to group A and B intrathecally for spinal anesthesia. We investigated the onset and the duration of spinal anesthesia along with hemodynamic changes (blood pressure and heart rate) in patients. RESULTS: There were no significant differences in the onset of spinal anesthesia and hemodynamic changes between two groups. The time taken to recover from the nerve block was more prolonged in the group B (touch 225, pain 262, foot dorsiflexion 271, knee flexion 290 minutes) than group A (touch 154, pain 188, foot dorsiflexion 198, knee flexion 216 minutes). There were no significant differences in sedation, and in experiencing dry mouth and other side effects between two groups. CONCLUSION: Intrathecal clonidine 150 g has been proved to prolong the duration of hyperbaric 0.5% bupivacaine spinal anesthesia without neurotoxicity or dangerous hemodynamic depression. Therefore, clonidine can be used as an effective adjunct in hyperbaric bupivacaine spinal anesthesia.

Microglia are recognized as residential macrophageal cells in the brain. Activated microglia play a critical role in removal of dead or damaged cells through phagocytosis activity. During phagocytosis, however, microglia should survive under the harmful condition of self-producing ROS and pro-inflammatory mediators. TGF-beta has been known as a classic anti-inflammatory cytokine and controls both initiation and resolution of inflammation by counter-acting inflammatory cytokines. In the present study, to understand the self-protective mechanism, we studied time-dependent change of TNF-alpha and TGF-beta production in microglia phagocytizing opsonized-beads (i.e., polystyrene microspheres). We found that microglia phagocytized opsonized-bead in a time-dependent manner and simultaneously produced both TNF-alpha and TGF-beta. However, while TNF-alpha production gradually decreased after 6 h, TGF-beta production remained at increased level. Microglial cells pre-treated with lipopolysaccharides (a strong immunostimulant, LPS) synergistically increased the production of TNF-alpha and TGF-beta both. However, LPS-pretreated microglia produced TNF-alpha in a more sustained manner and became more vulnerable, probably due to the marked and sustained production of TNF-alpha and reduced TGF-beta. Intracellular oxidative stress appears to change in parallel with the microglial production of TNF-alpha. These results indicate TGF-beta contributes for the survival of phagocytizing microglia through autocrine suppression of TNF-alpha production and oxidative stress.

PURPOSE: The aim of this study was to compare the health-related quality of life (HQOL) and depression in prostate cancer patients with radial prostatectomy or hormonal therapy more than 6 months ago. METHODS: A total of 116 patients participated in the study (83 radical prostatectomy patients and 33 hormonal therapy). Data were collected from 13th September to 13th November 2012, using two instruments-translated into Korean: Expanded Prostate Cancer Index Composite and Geriatric Depression Scale Short Form. RESULTS: Hormonal therapy participants reported significantly higher scores of HQOL than radical prostatectomy participants did (p=.002). The HQOL subscales with significant differences were urinary function (p<.001) and incontinence (p<.001) under urinary domain and sexual bother (p<.001) under sexual domain. The level of depression was not significantly different between the two treatment groups. There were moderate negative correlations between HQOL and depression in both groups. CONCLUSION: Many of prostate cancer patients reported treatment-related functional deteriorations in urinary and sexual domains and they were depressed even more than 6 months after the treatment completion. To manage prostate cancer patients' HQOL and depression, clinicians including nurses should evaluate patients' complaints according to their treatment modality and intervene accordingly.

Cigarette smoking has long been recognized as a major risk factor in the development of coronary heart disease. Several investigators have reported the strong association between smoking and high serum cholesterol, triglyceride concentration, SFA and low HDL cholesterol, PUFA and omega6 concentrations. Therefore, this study was done to investigate the effect of smoking on the serum lipid profile and fatty acid composition of college women. Sixty-one non-smokers and twenty-seven smokers were selected from college women students in the Seoul area. Their lipid intake, serum lipid concentration and fatty acid composition were examined. There were no differences in the general characteristics and anthropometric indices between the smokers and non-smokers. However, alcohol consumption was significantly higher in smokers than non-smokers (p<0.001). The daily caloric intake of smokers and non-smokers were 1875.84 kcal and 1915.53 kacl, respectively. On the other hand, the mean daily intake of lipids and cholesterol were significantly lower in smokers (p<0.05). In smokers, the mean concentrations of serum total cholesterol, LDL-cholesterol and the LDL-C/HDL-C ratio were higher, and the compositions of EPA and DHA were lowe than in non-smokers. There was a negative correlation between the serum triglyceride and PUFA levels in the two groups. Also, serum HDL-C correlated negatively with MUFA in smokers and non-smokers (p<0.01). These results suggest that smoking cause inadequate changes in serum lipid profile and serum fatty acid composition, thereby increasing the tendency for coronary heart disease.
