Domain transfer is a widely recognized problem for machine learning algorithms because models built upon one data domain generally do not perform well in another data domain. This is especially a challenge for tasks such as opinion classification, which often has to deal with insufficient quantities of labeled data. This study investigates the feasibility of self-training in dealing with the domain transfer problem in opinion classification via leveraging labeled data in non-target data domain(s) and unlabeled data in the target-domain. Specifically, self-training is evaluated for effectiveness in sparse data situations and feasibility for domain adaptation in opinion classification. Three types of Web content are tested: edited news articles, semi-structured movie reviews, and the informal and unstructured content of the blogosphere. Findings of this study suggest that, when there are limited labeled data, self-training is a promising approach for opinion classification, although the contributions vary across data domains. Significant improvement was demonstrated for the most challenging data domain-the blogosphere-when a domain transfer-based self-training strategy was implemented.

Purpose. This study was done to identify and test a model of the psychosocial variables that influence adherence to therapeutic regimens in patients with hypertension. Method. A convenience sample of 219 patients with hypertension who were enrolled in an outpatient clinic of a cardiovascular center in Korea participated in the study. They completed self-administered questionnaires anonymously. The questionnaire was based on the Social Action Theory model and a literature review. The explanatory model was constructed and tested using structural equation modeling in order to examine the effects within the model. Results. The results of this study showed that perceived self-efficacy was the strongest factor influencing patient adherence in this sample. Adherence to therapeutic regimens in patients with hypertension was influenced by self-efficacy, patient-provider relationship, social support, and depression. Conclusions. Adherence to therapeutic regimens in patients with hypertension was most strongly influenced by self-efficacy. These findings suggest that nursing interventions to promote patient adherence should focus on the promotion of self-efficacy including improvement in patient-provider relationship and social support, and reduction in depression.

Purpose: The purpose of this study was to examine the effects of microteaching for student health educators. Methods: Subjects included 43 students in the nursing department of "H" university. In order to measure the degree of self-efficacy and speech anxiety at pre-treatment and post-treatment, subjects in the experimental group underwent training in microteaching. Results: No significant difference of variance in self-efficacy and speech anxiety was observed between subjects in the experimental group and those in the control group. However, self-confidence, a sub-domain of self-efficacy, showed a significant increase from pretest to post-test. In addition, speech anxiety measured during the post-test showed improvement, when compared with that of the pretest. Conclusion: Findings of this study provide preliminary evidence that microteaching may result in improved speech behavior.

In this paper, we propose the effects of programming-based TPACK educational program on the pre-service teacher's self-efficacy beliefs for technology integration. For this study, pre-service teachers who received programming education and TPACK education based on ICT were set as control group and pre-service teachers who received programming-based TPACK education as experimental group. In order to observe the change, the pre-service teachers conducted the test tool to measure the self-efficacy beliefs for technology integration before and after applying the educational program. As a result of the study, only the pre-service teachers who received the programming-based TPACK education showed significant improvement in the self-efficacy beliefs for technology integration. Furthermore, in the post-test, the experimental group showed a significantly higher difference than the control group. Through this study, it was concluded that programming-based TPACK educational program is effective in enhancing pre-service teacher's self-efficacy beliefs for technology integration.

Many studies have reported that regular aquatic exercise can lead to improvement of health for patients suffering from arthritis. In spite of these benefits, the adherence rate has shown as few as 26% of patients with arthritis who had completed the aquatic exercise education program. Moreover, when patients with arthritis begin an aquatic exercise, 47% withdraw within the first 6 month. No study has been found that constructs model to explain aquatic exercise adherence of patients with arthritis. The purpose of this study were to identify the factors influencing exercise adherence and to construct and test a structural model to explain aquatic exercise adherence of patients with arthritis. Hypothesized model was constructed on the basis of Bandura's social cognitive theory and literature review. Exogenous latent variables included in this model are group cohesion and barrier, endogenous latent variables are self-efficacy, outcome expectancy and self-evaluation. Empirical data used was collected through individual interviews with the structural questionnaire on 249 patients with arthritis who had completed the 6-week aquatic exercise education program of Korean Rheumatology Health Professionals Academy. The interviews were performed from September 6, 1999 through October 8, 1999. A model tested by the covariance structural analysis with LISREL 8.12a program and by descriptive statistics and correlation with SAS 6.12 program. The results are summarized as follows: First, hypothesized model showed a good fit to the empirical data. In the modified model added one new path showed a much better fit. Second, group cohesion had a direct, indirect positive effects, self-efficacy and self evaluation had a direct positive effects on exercise adherence. Barrier had a direct, indirect negative effects on exercise adherence. Outcome expectancy had a direct negative effect, indirect positive effects through self-evaluation on exercise adherence, but total effects was not significant. Total effect size of the variables were group cohesion, self-efficacy, barrier and self evaluation in order. All variables accounted for 54% of the total variance of exercise adherence in the model. In conclusion, this model confirmed to be proper in explaining of aquatic exercise adherence. Group cohesion, self-efficacy, outcome expectancy, self-evaluation, barrier contributed to the aquatic exercise adherence of patients with arthritis. The results of this study suggested that improvement of group cohesion, self-efficacy and self-evaluation, motivation of outcome expectancy through self-evaluation, and reduction of the barrier should be included in the strategy of nursing intervention for the aquatic exercise adherence of patients with arthritis.

Purpose: This study was conducted to evaluate effects of a comprehensive lifestyle improvement program for middle-aged women with cardio-cerebrovascular disease (CVD)-related risk factors. Methods: The research adopted a non-equivalent control group pretest-posttest design. The number of participants was 18 in the experimental group and 16 in the control group sampled among middle-aged women who had CVD-related risk factors residing in a community. The experimental group participated in a four-session comprehensive lifestyle promotion program, which consisted of lectures, demonstrations, small-group meetings and telephone-counseling. The effects of the program were evaluated by measuring knowledge, attitude, health behavior, and self-efficacy for CVD prevention. Results: The experimental group showed a significant increase in self-efficacy for CVD prevention compared to the control group. There was no significant increase in knowledge, attitude, and health behavior. Conclusion: The results suggest that the comprehensive lifestyle improvement program was effective in improving self-efficacy for CVD prevention. There is a need to develop more effective lifestyle improvement programs designed to improve knowledge, attitude, and health behavior for CVD prevention. In further research, a follow-up evaluation is also needed to investigate any delayed effects on targeted variables among which no significant differences emerged immediately after the completion of the program.

Purpose: To examine the effect of menstrual self-management education program on knowledge and behavior of menstrual self-management in high school girls. Methods: With a randomized controlled trial, 100 high school girl students were randomly assigned into experimental group and control group. Menstruation self-management program was consisted of a total of four sessions of education program (1 hour of education per session). Control group only received the first class of education. Measurement tools were 20-item menstrual knowledge scale and 12-item women's genito-urinary hygiene scale. Pretest and post-test questionnaires were administered. Results: There were significant differences in menstrual knowledge as well as menstrual self-management behavior between the two groups. The experimental group showed significant improvement in both menstrual knowledge score (t=13.37, p<.001) and menstrual self-management behavior score (t=8.38, p<.001) than the control group. Conclusion: Results of this study suggest that the monthly self-management education program is effective in increasing the knowledge of menstruation of female high school students and enhancing their performance. This program needs to be implemented as a part of high school's standard sex education. Further study is needed to analyze follow-up effects of the program on self-management behavior of students after at least one menstrual cycle.
