PURPOSE: This study was done to develop and test a structural model on smoking cessation intention in technical high school men. The conceptual model was based on the theory of reasoned action and health promotion model. METHODS: From May 29 to April 13, 2015, 413 technical high school students who smoked completed a structured questionnaire. Data were analyzed to calculate the direct and indirect effects of factors affecting smoking cessation intention. The SPSS WIN 20.0 and AMOS 21.0 programs were used. RESULTS: The hypothetical model was a good fit for the data. The model fit indices were χ²/df=2.36, GFI=.95, AGFI=.92, NFI=0.97, and RMSEA=.05. Self-esteem had direct and indirect effects on smoking cessation intention. Attitude, subjective norm, and self-efficacy had direct effects on smoking cessation intention. Smoking knowledge and environmental factor had indirect effects on smoking cessation intention. This model explained 87.0% of the variance in smoking cessation intention. CONCLUSION: These results indicate that technical high school students' intention to stop smoking can be improved through an increase in self-esteem, negative environmental factors, attitude toward smoking cessation, subjective norm about smoking cessation, and self-efficacy for smoking cessation.

PURPOSE: This study was done to identify factors based on the theory of planned behavior that predict smoking cessation in elderly smokers following a stroke. METHOD: Between March and May 2013, data related to intention, attitude toward the behavior, subjective norm, and perceived behavioral control, were collected through questionnaire from 223 elders who smoked and who had a stroke. Data analysis was performed using PASW (SPSS) 18.0 program, and included t-test, one-way ANOVA, Pearson correlation coefficients, and multiple stepwise liner regression analysis. RESULTS: Results showed a positive correlation between intention and attitude toward the behavior (r=.494, p<.001), subjective norm (r=.390, p<.001), and perceived behavioral control (r=.189, p=.005). These variables such as perceived behavior control, subjective norm, number of cigarettes per day, and usefulness of quitting smoking explained 50% of intention to quit smoking. CONCLUSION: The results of this study indicate that there is a need to develop smoking cessation nursing strategies for elderly smokers following a stroke in order to provide effective counseling on subjective norm and perceived behavioral control.

PURPOSE: This study was done to identify the factors influencing customer orientation of nurses. METHOD: The participants were 505 nurses who were working in 13 hospitals. Data were collected with structured questionnaires in Feb., 2012, and analyzed using descriptive statistics, t-test, one way- ANOVA, Scheffe test, correlation coefficient, and hierarchical regression with PASW (SPSS) 18.0 program. RESULT: The average score for internal marketing was 3.07 points, for job satisfaction, 3.06 points, for organizational commitment, 3.25 points, and for customer orientation, 3.53 points. Customer orientation was positively correlated with internal marketing, job satisfaction and organizational commitment. The significant predictors of customer orientation were professionalism, interaction with job satisfaction, affective commitment, continuous commitment to organizational commitment and length of career. These variables had an explanatory power of 45.2%. CONCLUSIONS: The study findings suggest that internal marketing, job satisfaction, and organizational commitment should be reinforced to improve the customer orientation of nurses.

PURPOSE: This study was done to explore clinical competence and factors related to competence in nursing students. METHODS: Data were collected using structured questionnaires from 210 students in three different schools located in D, B and P metropolitan cities, Korea. Data were using PASW (SPSS) 18.0 program, and included t-test, one-way ANOVA, Pearson correlations coefficients, and multiple regression analyses. RESULTS: There were positive correlations between clinical competence and ego-resilience (r=.40. p<.001), critical thinking dispositions (r=.58, p<.001), and self-leadership (r=.14, p=.043). Variables such as critical thinking dispositions, ego-resilience, satisfaction with clinical practice education, health status and academic performance explained 48% of variance in clinical competence. CONCLUSION: According to the above results, a specific education program for clinical competence of student nurses is needed to increase critical thinking dispositions, ego-resilience, satisfaction with clinical practice education, health status and academic performance.

PURPOSE: This study was done to examine sexual autonomy of college students. METHOD: Between October 2012 and November 2012, data related to self-efficacy, health knowledge, attitude to sex, and sexual autonomy orientation, were collected by questionnaire from 232 students. The data analysis was performed using PASW (SPSS) 18.0 program, and included t-test, one-way ANOVA, Pearson correlation coefficients, and multiple stepwise liner regression analysis. RESULTS: The results showed a positive correlation between self-efficacy and sexual autonomy (r=.56, p<.001), sexual health knowledge (r=.50, p<.001), and attitude to sex (r=.29, p=.001). These 4 variables accounted for 48.7% of the variance in sexual autonomy among college students. CONCLUSION: The results of this study indicate that there is a need to develop mental health nursing strategies for college students in order to provide effective counseling on sexuality and sexual health matters.

OBJECTIVES: Cord blood stem cells have been widely used as donor cells for bone marrow transplantation recently. These cells can give rise to a variety of hematopoietic lineages to repopulate the blood. Recent observations reveal that some bone marrow cells and bone marrow stromal cells(MSCs) can grow to become either neurons or glial cells. It is, however, unclear whether or not there exists stems cells which can differentiate into neurons in the blood during the early stages of postnatal life. METHODS: Human cord blood stem cells were prepared from human placenta after full term delivery. To induce neuronal differentiation of stem cells, beta-mercaptoethanol was treated. To confirm the neuro-glial characteristics of differentiated stem cells, immunocytochemical stain for NeuN, neurofilament, glial fibrillary acidic protein(GFAP), microtubule associated protein2(MAP2) was performed. RT-PCR was performed for detecting nestin mRNA and MAP2 mRNA. RESULTS: We showed in this experiment that neuro-glial markers(NeuN, neurofilament, MAP2, GFAP) were expressed and axon-like cytoplasmic processes are elaborated in the cultured human cord blood stem cells prepared from new born placenta after full term delivery. Nestin mRNA was also detected in fresh cord blood monocytes. Conclusions: These results suggest that human cord blood derived stem cells may be potential sources of neurons in early postnatal life.

The purpose of this study was to assess the physical activity level of Korean farmers to establish their estimated energy requirements during busy farming season. 113 farmers (mean age 51.9 +/- 7.2 years, male 42, female 71) who own farmland area above 300 pyung participated in measurement of body weight and height and interviewing of one-day activity diaries. There was no significant difference in age, BMI between male and female. Obesity prevalence according to BMI among male and female farmers was 40.5% and 50.7% respectively. The farmers spent about 7 hours in sleeping and spent about 4 hours 35 minutes working on the farm and spent about 15 hours 30 minutes (64.6% of 24 hours) in "very light activities" and spent about 3 hours 31 minutes (14.7%) in "light activities". Physical activity level (PAL, activity coefficient) of male farmers was 2.63 which was significantly higher than that (2.19) of female farmers (p < 0.05). Estimated energy requirements (EER) for farmers who were different in age and gender were suggested. For example, the estimated energy requirements for male and female farmers were 3058 kcal/day and 2279 kcal/day, respectively. The results of this study suggest that estimated energy requirements (EER) of farmers should be differentiated according to seasonal workload and energy balance of farmers should be evaluated to prevent obesity.

BACKGROUND: Menstrual irregularity is a common major complaint in women of reproductive age. It is also a known marker for underlying insulin resistance. We investigated the association between menstrual irregularity and metabolic syndrome in the general population of middle-aged women in Korea. METHODS: This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey 2010-2012. A total of 2,742 subjects were included in the analysis. Participants were divided into two categories based on their menstrual cycle regularity and the relationship between metabolic syndrome and its variables was investigated by multiple logistic regression analysis. RESULTS: Adjusted analyses revealed significantly higher odds ratios for metabolic syndrome, high waist circumference, high triglyceride levels, and low high density lipoprotein cholesterol levels with the presence of menstrual irregularity. CONCLUSION: Metabolic syndrome and its components (high waist circumference, high triglyceride levels, and low high density lipoprotein cholesterol levels) were significantly associated with menstrual irregularity in women of reproductive age.
