The purpose of this study is to investigate how certain factors-especially dietitians' general characteristics and job burnout-influence their job satisfaction and turnover intention. The survey was conducted during the period from September 7th to October 15th of 2006. A total of 91 institutions(response rate 74.6%) was analyzed by using SPSS(windows ver. 14.0). A majority of the respondents were females(97.8%) and 30 years or older(66.0%). Among the job burnout dimensions, exhaustion($2.78{\pm}0.07$) was rated higher than cynicism($2.62{\pm}0.06$), while the professional efficacy level($3.55{\pm}0.05$) was relatively high. The dietitians were more satisfied with co-workers($3.73{\pm}0.07$) and work($3.41{\pm}0.06$) than with pay($2.66{\pm}0.07$) and promotion($2.32{\pm}0.07$). The work dimension of job satisfaction was negatively correlated with exhaustion and cynicism dimensions of job burnout, and turnover intention(p<0.001), but positively correlated with professional efficacy dimension(p<0.001). The supervision dimension was negatively correlated with cynicism(p<0.05) and turnover intention(p<0.001), but positively correlated with professional efficacy dimension(p<0.01). The co-workers dimension was positively correlated with professional efficacy dimension(p<0.01). The pay dimension was negatively correlated with exhaustion(p<0.001) and cynicism(p<0.01) dimensions and turnover intention(p<0.001). The promotion dimension was negatively correlated with cynicism(p<0.01). The turnover intention was positively correlated with exhaustion and cynicism dimensions of job burnout(p<0.001). A hierarchical regression analysis revealed that i) professional efficacy was a factor to significantly increase job satisfaction, ii) cynicism to significantly decrease their job satisfaction, and iii) exhaustion to significantly increase turnover intention.

Purpose: The purpose of this study was to evaluate the effectiveness of 8 weeks smoking cessation program(SCP) developed by researchers. Method: One group pretest-posttest design was used in this study. The subjects were 88 male university students who consented to participate in the 8 weeks SCP. The SCP in this study consisted of a stop-smoking class, e-mail, SMS(short message service), cellular phone, internet cafe, displayed panel, and patch or acupuncture for quitting smoking. Korean version of questionnaire for nicotine dependency by Ahn et al.(2002), the smoking self-efficacy scale translated by Choi(1999) and subjects' opinion about the SCP were measured. The data were analyzed by using frequency, Chi-Square test, paired t-test and repeated measures ANOVA with SPSS WIN 10.1 Program. Results: 1) The rate of quitting smoking was 31.8% after 8 weeks SCP. 2) There was no significant decrease in the nicotine dependency score among smoking subjects after SCP. 3) There was a significant increase in self-efficacy after SCP. The mean score of self -efficacy in the quitting smoking group increased significantly, but did not significantly change in the smoking group. 4) The stop-smoking class was the most helpful among contents of the SCP. Contents of the SCP except for internet cafe were useful for quitting smoking in this study. Conclusion: The above results indicated that the 8 weeks SCP would be a helpful intervention to quit smoking for male university students.

Objective: To investigate the correlation between ERCC1 expression levels in tumor tissue and peripheral blood lymphocytes (PBL) from patients with gastric cancer and assess the relationship between PBL DNA repair rate (DRR) and the efficacy of platinum chemotherapy. Methods: A total of 53 patients with gastric cancer receiving surgery and 20 controls were studied. ERCC1 protein expression in tumour tissue and PBL were determined by immunohistochemical staining. The PBL DRRs of 47 advanced patients and 20 controls were estimated by comet assay. Results: The positive expression rates of ERCC1 were 67. 9%, 56. 6% and 10.0% in tumour tissues, PBLs of gastric cancer patients, and PBLs of the control group. PBL ERCC1 expression correlated with that in tissue (${\chi}^2$=15. 463, p=0.000). Pearson contingency coefficient=0.475). DRRs of cancer patients by tail length (TL) (Z=4. 662, p=0.000) and tail moment (TM) (Z=3. 827, p=0.000) were significantly lower than that of control group. When TL was applied as an indicator, the correlation between DRR and chemotherapy efficacy was significant (Spearman rank correlation r=0.327, p=0.032). Patients with low levels of DRR in PBL presented better short-term efficacy of chemotherapy than those with high levels of DRR. Conclusions: The ERCC1 expression in PBLs may indirectly reflect ERCC1 expression in gastric cancer tissues. Compared with non-cancer populations, patients with gastric cancer may have lower DNA repair capacity. DRR in PBL may predict the short-term efficacy of platinum-based chemotherapy for patients with advanced gastric cancer.

Objectives : This study was performed to evaluate the relationships between psychosocial characteristics and changes in the stage of breast cancer screening behavior. Methods : The 474 study subjects were randomly sampled from 21,459 women(age range, 40-70 years) who were eligible for the Korean National Cancer Screening Program in 2006 in Jinju, Gyeongsangnam-do. The information, including behaviors and sociodemographic characteristics, attitudes, subjective norms and self-efficacy, was collected by trained interviewers via home visits. The breast cancer screening stages were grouped as precontemplation, contemplation, action, maintenance and relapse, according to Rakowski. Results : Of the 474 women, 18.8% were in the precontemplation stage, 23.3% were in the contemplation stage, 13.1% were in the action stage, 36.6% were in the maintenance stage, and 8.2% were in the relapse stage. The distribution of stages was associated with attitude, subjective norms and self-efficacy(p for trend<0.01). To investigate the overall relationship between the variables, we conducted a linear structural equation model analysis based on the theory of planned behavior. The subjective norms and self-efficacy influenced the stage of the women's screening behavior. Conclusions : We should target on self-efficacy about the screening behavior of women by performing timely, thoughtful interventions. The support from family members, friends and other people is crucial for women to undergo breast cancer screening and to improve the breast cancer screening rate.

The purpose of this research was to examine the effect of dance sports for twelve weeks on physical self-efficacy in post-menopausal depression obese women. A total 38 women participated in this study, and they were divided into three groups: mild-depression group(n=9), light-depression group(n=14) and control group(n=15). For the exercise program in this study, a dance sports program performed at an intensity of heart rate reserve 50~80%, 60 minutes of exercise time, and the frequency of 3 times a week. Physical self-efficacy for mild-depression group after 12-week dance sports program was significantly increased compared to before the exercise. Although light-depression group and control group didn't show significant increase in physical self-efficacy, dance sports is expected to act positively on mental stability, such as depression and hope used as an effective tool to improve the quality of life. Furthermore, we expect a convergence is achieved between the sports science and medical research sectors.

The purpose of this study is to examine the influence of perceived career barriers to career compromise of university students who are looking for jobs. In this research, career barriers are classified interior barriers and exterior barriers and the moderate effect was verified on the relation between both barriers and career compromise. The collected 280 survey sheets were analyzed using regression analysis. As results, both career barriers affect on the career compromise positively. And self-efficacy has a moderate effect on the relation between career barriers and career compromise. These findings show that self-efficacy can help students overcome their career barriers. In the further studies, it is necessary to examine whether the employee' job satisfaction and turnover rate are related to self-efficacy.

BACKGROUND/OBJECTIVES: Existing evidence on lifestyle modification programs for weight loss is limited by the high attrition rate of such programs. Identifying predictors of adherence to a lifestyle modification program could result in program improvement. However, little is known about behavior-specific adherence and its psychological predictors. This study aimed to examine the psychological predictors of adherence after one-month participation in a community-based lifestyle modification program among Chinese overweight and obese adults in Hong Kong. SUBJECTS/METHODS: A total of 205 Chinese overweight and obese adults aged $38.9{\pm}10.5years$ completed the study. Data were collected at baseline and after one month using self-reported questionnaires, which assessed knowledge (self-developed scale), motivation (Treatment Self-Regulation Questionnaire), stage of change (Stage of Exercise Scale) and self-efficacy (Self-Rated Abilities for Health Practices Scale). At one month, a 4-day dietary recall and the International Physical Activity Questionnaire-Short Form were used to assess dietary and physical activity (PA) adherence. Food and PA diaries were examined to indicate self-monitoring. Program attendance was tracked between baseline and one-month follow-up. RESULTS: After one month, participants reported high dietary adherence, attendance, and adherence to self-monitoring but low PA adherence. Multiple regression analyses suggested that diet self-efficacy (baseline) and nutrition knowledge (one-month change) were independent predictors of dietary adherence score at one month, whereas autonomous PA motivation (baseline) and PA self-efficacy (both baseline and one-month change) were independent predictors of PA adherence score at one month. No significant psychological predictor was identified for attendance or self-monitoring. CONCLUSIONS: The results suggest that the effect of psychological factors on adherence differs between diet and PA adherence outcomes. To promote adherence, practitioners should assess self-efficacy, knowledge, and motivation at the beginning of a weight-loss program and explore behavior-specific strategies to improve knowledge and self-efficacy. The results of this study have direct implications for program improvements.

The advent of B-ISDN using ATM(asynchronous transfer mode) made possible a variety of new multimedia services, however it also created a problem of congestion control due to bursty nature of various traffic sources. To tackle this problem, UPC/NPC(user parameter control/network parameter control) have been actively studied and DRLB(dynamic rate leaky bucket) algorithm, in which the token generation rate is changed according to states of data source andbuffer occupancy, is a good example of the UPC/NPC. However, the DRLB algorithm has drawbacks of low efficiency and difficult real-time implementation for bursty traffic sources because the determination of token generation rate in the algorithm is based on the present state of network. In this paper, we propose a more plastic and effective congestion control algorithm by combining the DRLB algorithm and neural network based prediction to remedy the drawbacks of the DRLB algorithm, and verify the efficacy of the proposed method by computer simulations.
