Purpose: The purpose of this study was to identify variables influencing task performance of wound ostomy continence nurses (WOCN). Methods: Data were collected from 80 WOCN in Korea from September to October 2011 using a self-reported questionnaire. Variables consisted of task performance, empowerment, professional autonomy, job satisfaction and job-related variables. Data were analyzed by frequencies, t-test, one-way ANOVA, Pearson's correlation coefficient and stepwise multiple regression. Results: Professional autonomy was a major predictor of task performance of WOCN (F=37.37, p=<.001). Empowerment(F=33.10, p=.001) and completion of the professional education course for wound ostomy continence nursing WOCN(F=7.46, p=.008) were the other significant predictors of task performance. The regression model explained 45.3% of task performance. Conclusion: Professional autonomy, empowerment and completion of the professional education course contribute to task performance of WOCN. These findings have important implications for organizations hoping to achieve the maximum potential of WOCN's professional role. Therefore, strategies for reinforcement of professional autonomy, empowerment, and completion of professional education course are necessary for WOCN working in South Korea.

The main objective of this study is to investigate the influence of utterance internal pause in English speaking evaluation. To avoid possible confusion with other errors caused by segmental and prosodic inaccuracy, stem utterances with two different length obtained from a native speaker were manipulated to make a set of stimuli tokens through insertion of pauses whose length and position vary. After a total of 90 participants classified into three proficiency groups rated the stimuli, the scored data set was statistically analyzed in terms of the mixed effects model. It was confirmed that predictors such as pause length, pause position and utterance length significantly influence raters' evaluation scores. Especially, a dominating effect was found in such a way that raters gradually deducted scores in accordance with the increase of pause duration. In another experiment, a tree-based statistical learning technique was utilized to check which of the significant predictors played a more influential role than others. The findings in this paper are expected to be practically informative for both the test takers who are preparing for an English speaking test and the raters who desire to develop more objective rubric of speaking evaluation.

Aim: To report the results of radiotherapy with or without chemotherapy in the patients with oral cancer. Methods: Over the 2003-2009 periods, a total number of 69 patients with squamous cell carcinoma of the oral cavity that refused surgery or had unresectable tumor were enrolled in this study. A total dose of 60 to 70 Gy (2 Gy per day) was given to the primary tumor and clinically positive nodes. In the patients with locoregionally advanced disease (57 patients with $T_3$, $T_4$ lesions and/ or $N^+$) induction chemotherapy following by concomitant chemoradiation was used. Induction chemotherapy consisted of 3 cycles of Cisplatin and 5-Flourouracil with or without Docetaxel. Weekly cisplatin was used in concomitant protocol. Kaplan-Meier method was used to calculate overall survival. Log-rank test and Cox regression model were used for comparison purposes. Results: Median follow-up was 32 months. The mean age of the patients was 59.2 years. The overall response rate after induction chemotherapy was 68.4%. Actuarial overall survival rates after 2 and 3 years were 38% and 26%, respectively. Clinical stage emerged as the only independent predictor of survival. Conclusion: Outcome of the patients with oral cancer is poor. Presenting with an advanced stage lesion contributed to this result. The role of chemotherapy in advanced cases remains to be defined.

Background: Esophageal squamous cell carcinoma (ESCC) accounts for most esophageal cancer in Asia, and is the sixth common cause of cancer-related deaths worldwide. Previous studies indicated HOXB7 is overexpressed in ESCC tissues, but data on prognostic value are limited. Methods: A total of 76 advanced ESCC cases were investigated. Immunohistochemistry (IHC) was used to detect the expression levels of HOXB7 and Kaplan-Meier curves and Cox regression models to determine prognostic significance. Stratified analysis was also performed according to lymph node (LN) status. Results: Kaplan-Meier curve analysis indicated that HOXB7 positive patients had significantly shorter overall survival (OS) than HOXB7 negative patients. Multivariate analysis using the Cox proportional hazards model indicated only TNM stage and HOXB7 expression to be independent predictors of overall survival of advanced ESCC patients. HOXB7 indicated poor OS in both lymph node negative (LN-) and lymph node positive (LN+) patients. Conclusion: HOXB7 predicts poor prognosis of advanced ESCC patients and can be applied as an independent prognostic predictor.

Drawing on the theoretical framework of customer value-satisfaction-loyalty, this study examines how scarcity message influences customers' value, satisfaction, and loyalty in the context of group-buying social commerce. Previous studies have argued that scarcity message limiting the avilability of products and service is a source of enhancing customer value. In this regard, this study posits scarcity message as a predictor of customer value. Furthermore, this study classifies customer value into two forms (i.e., utilitarian value and hedonic value) and verfies how scarcity message is associated with them. To test the proposed research model and hypotheses, this study performed structural equation modeling (SEM) analyses, using a total of 292 data collected on users who have experience in purchasing products and service through group-buying social commerce sites such as Coupang, Timon, and WeMakePrice. The key results are as follows : First, scarcity message increases utilitarian and hedonic values and further customer satisfaction. Second, utilitarian value increases customer satisfaction and repurchase intention while hedonic value has nothing to do with them. The findings imply that customers seek to maximize utilitarian value through group-buying social commerce. Finally, this study indicates that repuchase intention depends greatly on customer satisfaction.

The study examined the relationship between six broad personality traits(i.e., HEXACO; Honesty-humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness to experience), safety job performance, and traffic accidents of Korean occupational bus drivers. Based on the job performance model, we included safety participation as well as safety compliance as safety job performance. Analyses on the data from a total of 492 bus drivers showed that all HEXACO personality traits except Honesty-humility, were valid predictors for both safety compliance and safety participation. Honesty-humility was only related to safety compliance. Among the six personality traits, high conscientiousness and low emotionality were best predictors of safety job performance. As for traffic accidents, conscientiousness was a sole significant predictor. Furthermore, the mediation analysis showed that the effect of conscientiousness on traffic accidents was completely explained by safety compliance and safety participation. The implications of the current findings for practice and future research as well as the limitations of the current study were discussed.

This study was designed to examine the decision-making and family life satisfaction of the urban middle-aged housewives from the ecological perspective. The main purpose of this study was to investigate the effects of ecological enviornment variables(ie, natural physical-biological environment·social-cultural environment·human-built environment) and their dicision-making on their family life satisfaction. Also, it is to provide some fundamental information that helps to elevate the family life satisfaction of the unban middle-aged housewives. The subjects of this study were 305 housewives living in Seoul and Inchon area, whose age was from 40 to 59. The significant results were as follows: 1) Their decision-making was affected by the following variables in the order of health condition, fate-control orientation, husband’s support, monthly family income and the perception of the adequacy of household income. 2) The ecological environment variables which had an influence on family life satisfaction were the perception of the adequacy of household income, husband’s support, fate-control orientation, health condition and educational level. 3) From the regression analysis, the model was found to be highly significant, accounting for 44% of the variance. Thus, husband’s support was the strongest predictor variable.

The purpose of this study was to investigate the selected predictors of the health promotion behavior of the elderly in Kangseo-ku, Kangnam-ku, Seoul. The study used an ecological perspective approach in that a microsystem (i.e. self-esteem, locus of control, introversion-extraversion and socio-demographic characteristics), and the environment such as a mesosystem (i.e. marriage satisfaction) and a macrosystem (i.e. social support, participation of social activities, social image of the elderly, social attitude of the elderly) were explored. A structured questionnaire was used to interview a sample of 188 elderly. Hierarchicai regression analysis yielded the results that the magnitude of the importance of the microsystem was found to be larger than any other systems investigated. The most powerful predictor of the health promotion behavior of the elderly was 'age', followed by 'participation of social activities', 'education', 'social support', 'locus of control', 'marriage satisfaction', and 'sex'. The research model accounted for $55\%$ of the health promotion behavior of the elderly.

Purpose: This study was conducted to examine relationships among job satisfaction, job stress, and self-efficacy and to identify predicting factors on the job satisfaction among a general hospital nurses. Method: The subjects were 266 nurses working at C university hospital in G city. Data were collected using a self-reported questionnaires. The data were analyzed using t-test, one-way ANOVA, Scheffe test, Pearson's correlation coefficients, & multiple stepwise regression by SPSS 12.0 program. Result: The job satisfaction indicated a significant relationship to self-efficacy (r=.310, p<.001) and work stress (r=-.273, p<.001) respectively. The powerful predictors of job satisfaction were general self-efficacy (22.6%), over ￦2,500,000 at monthly income (7.3%), job stress (4.9%), work period at present unit (2.6%), which explained 41.3% of total variance of job satisfaction. It has been confirmed that the regression equation model of this research may serve as a predictor of clinical nurses' job satisfaction. Conclusions: We need to develop self-efficacy promoting and stress relief program for clinical nurses in order to improve job satisfaction.
