PURPOSE: This study is to investigate the effect of nurse's competency empowerment and boss' job competency recognition on work performance. METHODS: 216 nurses participated for data collection which was conducted from September 1, 2011 to September 10, 2011. The collected data were analyzed with SPSS/WIN 16.0 and with frequency test, ANOVA, Scheffe test and Multiple regression. RESULTS: Firstly, the work performance in accordance with subject's general characteristics was found to be significant in the 50s, graduate school or higher education, Roman Catholic, charge nurse and 21-years or older. Secondly, the correlation among nurse's competency empowerment, boss' competency recognition and work performance was found to be positively related (r=.501~.639, p<.001). Thirdly, competency empowerment was found to be the most effective factor for work performance, followed by boss' competency recognition and career year, and these factors accounted for 63.5%. CONCLUSION: As the results show that the work performance is highly affected by the nurse's competency empowerment, boss' competency recognition level and career level in clinical environment, effective education programs are required to provide an appropriate experience to both entry-level and experienced nurses, as well as to enhance boss' competency empowerment at the same time.

PURPOSE: The purpose of this study is to explore the perceptions of obesity and management behaviors of obese adolescents and their families in Korea. METHOD: Nine adolescents with moderate-degree obesity and of four their mothers of them were investigated using semi-structured interviews. RESULT: The perceptions of obesity was classified into four domains and obesity management behaviors was classified into three domains. The domains regarding the perceptions of obesity include definitions of obesity(a danger signal of health status, deviation status, symbols of growth), causes of obesity(out of balance), opinions about their obesity(contempt, negative preconception, superiority) and changes on thought and attitudes owing to obesity(shrinkage, repulsion, sustaining losses, decreased activity, decreased self-confidence, defensive behaviors). The domains regarding obesity management behaviors include attitude about the management of obesity(not having priority, optimistic view, ardent wish), management behaviors for correcting obesity(encouraging physical activity, control of diet, gathering information, trial of diet control), attitudes about performing the management behaviors for correcting obesity(inconsistency, non-autonomy, conflict). CONCLUSION: This study helps to enhance the understanding of the perception of obesity and management behaviors of obese adolescents and their families. Futhermore, based on this understanding, effective and appropriate heath management programs can be planned and conducted.

PURPOSE: The study is to investigate the effect of communication and self-leadership on nursing performance. METHODS: The subjects of study were composed of 358 nurses at a G city university hospital, tested with structured questionnaire from September 15 to 30, 2010. The collected data were analyzed with ANOVA, Pearson's correlation coefficients and multiple regression analysis. RESULTS: The level of communication, self-leadership, and nursing performance was 3.37, 3.38 and 3.70 respectively in average. The variables showing significant difference in communication were as follows: age, marital status, religious status, education, monthly income, work department and work experience. Also, the variables in nursing performance were as follows: age, marital status, religious status, education, education, monthly income, position, working department and work experience. Communication, self-leadership and nursing performance of nurse showed significant positive correlation. Nursing performance was positively correlated with monthly income, when it exceeded 2.01 million won, career experience and self-leadership (p<.001). These variables explained 53.7% of the regression model. CONCLUSION: Since monthly income, work experience, communication and self-leadership have positive effect on nursing performance, an effective strategy is required to improve self-leadership and nurse's communication.

PURPOSE: This study was done to provide data that would contribute to effective task performance in clinical nursing and development of nursing professional by understanding job stress, job satisfaction and organizational commitment according to Life Organization (LIFO) behavior types of novice nurses. METHODS: This study was a cross-sectional survey and the participants were 313 novice nurses who worked in one university hospital located in the city of Gwangju. Data were collected through the structured questionnaires that included general characteristics, job stress, job satisfaction, and organizational commitment scales. Collected data were analyzed using descriptive statistics, and ANOVA with SPSS/WIN 19.0. RESULTS: Regarding job stress according to LIFO behavior types of novice nurses, there were statistically significant differences between the favorable situation and the unfavorable situation. There were also statistically significant differences regarding the organizational commitment according to LIFO behavior types. CONCLUSION: The results indicate a difference in behavior patterns of novice nurses that suggest a need for education in order to reduce stress from the job and enhance organizational commitment by developing each nurse's preferred pattern and compensating for unfavorable patterns, as well. There also needs to be nursing resources that take into consideration behavior patterns of novice nurses.

PURPOSE: The purposes of this study are to discribe the high-resolution computed tomographic (HRCT) findings of pulmonary histiocytosis X and to evaluate the relationship between the extent of the lesion on HRCT and pulmonary function test (PFT). MATERIALS AND METHODS: We retrospectively analyzed the HRCT findings of 8 patients with pathologically proved pulmonary histiocytosis X. The morphological pattern and incidence of the lesions were evaluated. The extent of the lesions were correlated with the results of PFT by calculating Spearman correlation. RESULTS: The most common HRCT findings were thick-walled cysts (n=8) followed by nodules (n=7). Other associated findings were reticulation, ground-glass opacification, and conglomerate nodules. The extent of the disease on HRCT was correlated inversely with percent predicted value of functional vital capacity. CONCLUSION: Common HRCT findings of pulmonary histiocytosis X were cysts with irregular wall thickening and nodules. The extent of the disease on HRCT correlated with the severity of restrictive pattern of PFT.

PURPOSE: The purpose of this study was to identify the relationship between self-esteem and sexual attitude in healthcare college students, and also to provide a basis for sexual health education programs to help establish healthy sexual attitudes. METHODS: A survey was conducted with 218 unmarried students attending the healthcare colleges in B and U cities. Data were collected from October 15 to November 10, 2015 and analyzed using Stepwise multiple regression with SPSS PASW 18.0. RESULTS: Mean score for self-esteem was 3.23±0.46 out of 5 and sexual attitude 2.64±0.54 out of 5. Self-esteem and sexual attitude had a negative correlation (r=-.169, p=.012). Among sub-variables of sexual attitude, negative correlations were found between self-esteem and premarital chastity (r=-.207, p=.002), and between self-esteem and homosexual attitudes (r=-.167, p=.013). There were statistically significant differences in sexual attitude according to perceived intimacy with mother (β=-.228, p<.001), year in college (β=.135, p=.047), major (β=.148, p=.023), religion (β=-2.429, p=.016), and homosexual tendencies (β=.139, p=.037). These factors explained 14.6% of the variance in sexual attitude. CONCLUSION: Findings demonstrate the importance of self-esteem for sexual attitudes. This finding should be used in the development of healthcare college students, promotion programs to enhance healthy sexual attitudes.

BACKGROUND: Computers can in many ways improve the quality and efficacy of medical care. The purpose of this study was to perform a comprehensive survey of present computer use and investigate the factors affecting computer use by family physicians. METHODS: One thousand and 1250 family physicians were surveyed by mail from May to August, 1999. The survey protocol included demographic characteristics, opinions on computer use in medicine, present computer usages and wanted applications in the future. RESULTS: Of the 306 responses received, 291 responses were analysed. 91.4% replied that they used computers in the medical field, and 58.1% said they used computers during medical interview. Factors preventing computer use in medicine were cost(33%), time(16%), insufficient information(14%), the doctor-patient relationship(12%) and no perceived need(6%). While 46% of the responders who used computers in the medical field cited fellow doctors for their interest in computer use in the medical field, only 6.2% answered that medical societies or associations had promoted their interest. Present usage of computers included word processing, online communication, internet, medical insurance billing, in descending order. Factors affecting the present degree of computer use that were statistically significant, were the computer system used, factors preventing computer use and the present form of practice. CONCLUSION: Although, most family physicians use computers in the medical field, its use is still limited to a few areas.

BACKGROUND: This study was conducted to investigate the knowledge, anxiety and compliance with preventive behavior of Middle East respiratory syndrome (MERS) in liver transplant patients. METHODS: The participants in the study were 100 liver transplant patients at an outpatient clinic. The data were collected from May 20, 2016, to June 20, 2016. RESULTS: The knowledge score was 6.37±1.73 (range; 1~10) and the correct answer rate was 63.7%. The state anxiety score was 41.35±10.08 (range; 20~68) and the trait anxiety score was 39.60±8.85 (range; 22~59). The compliance with preventive behavior score was 35.70±5.23 (range; 21~45). Anxiety differed significantly according to education level (P=0.040) and occupation status (P=0.047). Compliance with preventive behavior differed significantly according to period after surgery (P=0.035). Compliance with preventive behavior and state anxiety (P=0.007) and trait anxiety (P<0.001) were negatively related. The factor that had the greatest effect on compliance with preventive behavior was trait anxiety (P=0.003). CONCLUSIONS: The epidemic of the MERS has already been completed and none of the subjects of this study has been infected with the MERS; however, patients with liver transplantation always have a risk of various opportunistic infections. If new infectious diseases such as MERS occur in the future, increased anxiety may decrease the practice of prevention. Therefore, anxiety experienced by liver transplant patients should be managed.

Certain types of somatic cells, as well as follicular cumulus cells associating with mammalian oocytes, are known to produce beneficial effects on in vitro fertilization and preimplantation development of mammalian eggs when they are present in oocyte culture medium. To investigate the nature of the effects of somatic cells, the resistance of mouse oocytes against chymotrypsin treatment was examined after culture within various cell conditioned media. When mouse oocytes matured for 17-18 hr in the presence of cumulus cells were treated with 1% chymotrypsin, half of them remained still alive even after 240 min (t50>240.0). In contrast half of mouse oocytes cultured without cumulus cells underwent degeneration within 65.0 min (t50= 65.0+/-13.2 min) of the same treatment. To see if the effects were due to the secretory products of cumulus cells, mouse cumulus cells were cultured for 20 hr in medium containing 0.4% BSA and the supernatant of culture medium (conditioned medium) was taken. After maturation in the cumulus cell conditioned medium, mouse oocytes exhibited t50 = 190.0 +/-10.8 min upon chymotrypsin treatment whereas half of oocytes cultured without conditioned medium degenerated within 25.5 min. Human granulosa cell conditioned medium gave similar effects such that oocytes matured in conditioned medium exhibited t50 = 183.3+/-19.1 min while t50 of control group oocytes was 60.0+/-6.8 min. Oocytes matured in vero cell conditioned medium exhibited t50 = 196.7+/-8.8 min. On the other hand, amniotic cell conditioned medium resulted in the chymotrypsin resistance of t50 = 80.0+/-8.4 min which was not statistically different from the control value of t50 = 48.0+/-13.2 min. Based upon these results, it is suggested that certain somatic cell types including cumulus cells might change the biochemical properties of mouse oocyte membrane during meiotic maturation as revealed by the enhanced resistance against chymotrypsin treatment. Such effects of somatic cells appear to be mediated via the secretory products rather than direct communication between somatic cells and oocytes.
