Purpose: The purpose of this study was to investigate the predictors of tuberculosis (TB) drugs in health care workers diagnosed with latent tuberculosis Infection (LTBI). Methods: This study was a descriptive correlation study. Data were collected by using a self-report questionnaire. The collected data were analyzed by -test, t-test, and logistic regression analysis. Results: There were involved 160 participants, 35 (21.9%) who took the TB drugs, and 125 (73.8%) who did not take the TB drugs. The predictors on taking TB drugs in health care workers with LTBI were subjective norms (OR=3.33, p<.001), perceived sensitivity (OR=2.67, p=.026), perceived barrier (OR=0.14, p=.014), and unmarried (OR=4.69, p=.006) than married, health care worker category 2 group (OR=5.84, p=.015) and 1 group (OR=4.25, p=.022) than 3, 4 group, sleep over 7 hours (OR=4.11, p=.022) than less 7 hours sleep. Conclusion: In order to promote the use of TB drugs in health care workers with LTBI, it is necessary that take intervention strategies to increase the subjective norms and perceived sensitivity and to decrease the perceived barriers.

Purpose: This study aimed to identify latent classes of behavioral problem trajectories in children with allergic diseases and investigate their predictors. Methods: This study used data from the 5th to 7th Panel Study of Korean Children. The participants included 840 children aged 4~6 years with allergic diseases. Statistical analyses were conducted using latent class growth analysis and multinomial logistic regression. Results: The trajectories of both internalizing and externalizing behavioral problems in children with allergic diseases were classified into five groups, that is deteriorative, recovering, changing 1 (decreasing-increasing), changing 2 (increasing-decreasing), and low state persistent group. For the internalizing behavioral problems, predictors were temperament, father's education, family interaction, and disconnection in peer interaction. For the externalizing behavioral problems, predictors child's gender, temperament, marital conflict, parenting stress, family interaction, and parenting environment. Conclusion: Deteriorative group has high-risk behavioral problems in children with allergic diseases. We suggest to provide interventions considering latent problem trajectories based on ecological environments for allergic children.

Purpose: This study aimed to identify the predictors of psychological well-being in middle-aged female workers by examining the relationship between positive psychological capital, job stress, and job satisfaction. Methods: Data were collected from 145 middle-aged female workers. A self-report questionnaire was used to assess the level of positive psychological capital, job stress, job satisfaction, and psychological well-being. SPSS/WIN version 23.0 was employed for data analysis. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. Results: The most significant predictors of psychological well-being in the participants were positive psychological capital, living standards, and hobby. These explained 39% of the variance for psychological well-being. Conclusion: We found that positive psychological capital, living standards, and hobby influenced the participants' psychological well-being. Therefore, to improve middle-aged female workers' psychological well-being, developing a program based on positive psychological capital management is necessary.

One of the most significant changes is the paradigm shift from teacher-centered learning to learner-centered learning. Along with this paradigm shift, understanding of characteristics of e-learners who are both system users and learners is needed. Before suggesting a comprehensive framework, this study proposes research model that can improve a learning performance using the flow theory. The results show that intrinsic interest and focused attention are significant predictors of learning performance. Especially, intrinsic interest is more important on learning performance than focused attention. Information quality and skill are found to be strong predictors of the intrinsic interest. Also, perceived ease of use, skill and computer self-efficacy are strong predictors of the focused attention.

Pipelines of processor have been growing deeper and issue widths wider over the years. If this trend continues, branch misprediction penalty will become very high. Branch misprediction is the single most significant performance limiter for improving processor performance using deeper pipelining. Therefore, more accurate branch predictor becomes an essential part of modem processors for FAFF(Food, Agriculture, Forestry, Fisheries)Information Processing. In this paper, we propose a branch prediction mechanism, using variable length history, which predicts using a bank having higher prediction accuracy among predictions from five banks. Bank 0 is a bimodal predictor which is indexed with the 12 least significant bits of the branch PC. Banks 1,2,3 and 4 are predictors which are indexed with different global history bits and the branch PC. In simulation results, the proposed mechanism outperforms gshare predictors using fixed history length of 12 and 13, up to 6.34% in prediction accuracy. Furthermore, the proposed mechanism outperforms gshare predictors using best history lengths for benchmarks, up to 2.3% in prediction accuracy.

Objectives : Biofeedback is a useful non-pharmacological treatment for panic disorder (PD), but no studies have identified physiological markers related to the treatment response. This study investigated predictors of the treatment response for biofeedback in patients with PD. Methods : A retrospective study based on the electronic medical records of 372 adult patients with PD was performed. Patients received biofeedback treatment at least once, and physiological markers including heart rate, heart rate variability, respiratory rate, skin conductance, skin temperature, and electromyography were collected before the treatment began. The patients were classified as responders or non-responders based on the change in Clinical Global Impression-Severity (CGI-S) score. Results : The response rate to biofeedback treatment was 30.4%. Multivariable logistic regression analysis revealed that a higher CGI-S score at baseline and fewer benzodiazepine prescriptions were associated with a better response to biofeedback treatment. According to subgroup analyses, the baseline CGI-S score, dose of benzodiazepines, and skin conductance are candidate predictors of the response to biofeedback treatment in men, while only baseline disease severity was associated with the treatment response in women. Conclusions : The present results suggest that skin conductance may be target marker and predictor for biofeedback in male patients with PD.

A survey of 220 male and 233 female residents of Seoul was carried out to investigate why women appeared to be more fearful of crime than men. As expected, female respondents reported higher levels of fear of crime and perceived physical vulnerability to crime. Incivility factors in the neighborhood and perceived possibility of criminal victimization were significant predictors of fear of crime for both male and female respondents. For women more psychological variables such as trait anxiety and age were other significant predictors of their fear of crime, whereas the distance to police station and frequency of watching crime-related TV programs were significant predictors for men's fear of crime.

Mixed urinary incontinence (UI) is common in women. This study aimed to assess the efficacy of anti-incontinence surgery in female patients with equally severe stress UI (SUI) and urge UI (UUI). All patients had equal severity of SUI and UUI. The postoperative cure rate was categorized into the cure group (CG) and failure group (FG). Postoperative satisfaction was categorized into the satisfaction group (SG) and the dissatisfaction group (DG). Statistical significance was set at P<0.05. Ninety patients (SG, 73.3%; DG, 26.7%; CG, 93.3%; FG, 6.7%) were included in the study. In the univariate analysis, body mass index (BMI), total bladder capacity, and overactive bladder symptom score (OABSS) were significantly different between the SG and DG groups. Peak urinary flow, Valsalva leak point pressure (VLPP), and OABSS were significantly different between the CG and FG groups. In the multivariate analysis, OABSS (P=0.001) and BMI (P=0.032) were independent predictors of postoperative satisfaction. VLPP (P=0.023) was the only independent factor associated with the postoperative cure rate. In equal severity of SUI and UUI, VLPP was found to be the only independent factor associated with postoperative cure rates. Higher VLPP values were associated with higher cure rates. BMI and OABSS were identified as independent predictors of postoperative satisfaction, with lower BMI and OABSS associated with higher postoperative satisfaction.

Homeless people have remained one of the most disadvantaged groups in Korea. Therefore this study aims at examining how the homeless evaluate their quality of life and which factors influence their quality of life. The subjects of this study were 185 homeless adults residing on the street, in the shelter, and in substandard housing in Daejeon Metropolitan City. With a view to collecting the data effectively, different approaches have been taken for each type of homelessness in this study. By using the Korean Version of WHOQOL-BREF(brief version of WHO quality of life measure), this study has examined the current circumstance of the homeless and identified the predictors of their quality of life. The results of this study reconfirm low quality of life of homeless people. Also the results of this study indicate that the important factors influencing their quality of life are age, receipt of public assistance, perceived health status, alcohol use, alcohol addiction, housing type, and recognition by others. Predictors of each domain of quality of life differ to some extent. Statistically significant predictors of physical health are receipt of public assistance, perceived health status, and housing type. Psychological health is significantly influenced by age, receipt of public assistance, perceived health status, housing type, and recognition by others. Significant predictors of social relations are alcohol use, housing type, and recognition by others. Environment is significantly influenced by perceived health status, housing type, and recognition by others. On the basis of the findings of this empirical analysis, some measures conducive to the improvement of quality of life of homeless people are suggested. Only a few studies have been conducted to delve into the quality of life of the displaced group in Korea. In such a context, the significance of this study lies in identifying the circumstances of the homeless as a basic work for upgrading their quality of life on the one hand, and in empirically testing the major predictors of each domain of their quality of life on the other.
