Objective: The purpose of this study was to apply the Basic CPR(Cardiopulmonary resuscitation) training education program and identify its effects on knowledge of Basic CPR and skills of Basic CPR in second grade high school students. Methods: The training program was conducted for 16 weeks between March 26 and July 9, 2005 using a non-equivalent control group pretest-post test design by dividing 60 students in a half for both the experimental group and the control group. General characteristics, the effect of the education were evaluated with $x^2-test$, t-test, ANCOVA, Repeated Measure ANOVA and Bonferonni with SPSS 11.0/pc. Result: After the CPR education program application, knowledge score in the experimental group increased to 20.57 right after the education from 9.32, the score measured before the training, 19.11 after 8 weeks and 18.29 after 12 weeks. On the contrary, the control group's score showed no significant before the training. According to the result of knowledge score comparison between the experimental and control group at each point in time, the experimental group had a significantly high score in knowledge at every point(p<0.001). In the effect durability for knowledge of the training education program in process time after the training program in the experimental group, the durability of effect was identified despite the elapsing time. Scores of skills for Basic CPR increased from 1.21, the score measured before the training program, to 30.07 right after the education, 23.50 after 8 weeks and 17.57 after 12 weeks in experimental group. On the contrary, the control group showed an immaterial increase. According to the result of skill score comparison between the experimental and control group at each point in time, the experimental group had a significantly high score in skill at every point(p<0.001). The score for skill increased significantly right after the education compared to the score prior to the education. Conclusions: These findings suggest that Basic CPR training education program facilitate knowledge of CPR and skill of CPR in high school students. Therefore, it would be necessary to include the Basic CPR training program in high school education curriculum. However, the effect of Basic CPR knowledge maintains for a few period, and the effect of maintaining the skill is shorter than the maintenance of knowledge so regular reeducation is considered to be needed.

According to a recent survey, most elementary and secondary school students nationwide are stressed out by their academic records. Furthermore most of high school students in Korea have to study under the great duress. Some of them who can't overcome the academic stress finalize their life by suiciding. A study has found that it is one of the leading causes of stimulating the thought of committing suicide in Korean high school students. So it is necessary to reduce the high school student's suicide rate. Main content of this research is to implement a personalized music recommendation system. Music therapy can help the student deal with the stress, anxiety and depression problems. Proposed system works as a therapist. The music choice and duration of the music is adjusted based on the student's current emotion recognized automatically from EEG. If the happy emotion is not induced by the current music, the system would automatically switch to another one until he or she feel happy. Proposed system is personalized brain music treatment that is making a brain training application running on smart phone or pad. That overcomes the critical problems of time and space constraints of existing brain training program. By using this brain training program, student can manage the stress easily without the help of expert.

Aiming at the problem of software defect prediction difficulty caused by insufficient software defect marker samples and unbalanced classification, a semi-supervised software defect prediction model based on a tri-training algorithm was proposed by combining feature normalization, over-sampling technology, and a Tri-training algorithm. First, the feature normalization method is used to smooth the feature data to eliminate the influence of too large or too small feature values on the model's classification performance. Secondly, the oversampling method is used to expand and sample the data, which solves the unbalanced classification of labelled samples. Finally, the Tri-training algorithm performs machine learning on the training samples and establishes a defect prediction model. The novelty of this model is that it can effectively combine feature normalization, oversampling techniques, and the Tri-training algorithm to solve both the under-labelled sample and class imbalance problems. Simulation experiments using the NASA software defect prediction dataset show that the proposed method outperforms four existing supervised and semi-supervised learning in terms of Precision, Recall, and F-Measure values.

Background: Hong Kong's construction industry currently faces a manpower crisis. Blue-collar workers are a disadvantaged group and suffer higher levels of chronic diseases, for example, cancer, than the wider population. Cancer risk factors are likely to cluster together. We documented prevalence of cancer-associated lifestyle risk behaviors and their correlates among Hong Kong construction workers. Methods: Data were collected from workers at 37 railway-related construction worksites throughout Hong Kong during May 2014. Tobacco use, alcohol consumption, unbalanced nutrition intake, and physical inactivity were included in the analysis. Latent class analysis and multivariable logistic regression were performed to identify the patterns of risk behaviors related to cancer, as well as their impact factors among construction workers in Hong Kong. Results: Overall, 1,443 workers participated. Latent class analysis identified four different behavioral classes in the sample. Fully adjusted multiple logistic regression identified age, gender, years of Hong Kong residency, ethnicity, educational level, and living status differentiated behavioral classes. Conclusion: High levels of lifestyle-related cancer-risk behaviors were found in most of the Hong Kong construction workers studied. The present study contributes to understanding how cancer-related lifestyle risk behaviors cluster among construction workers and relative impact factors of risk behaviors. It is essential to tailor health behavior interventions focused on multiple risk behaviors among different groups for further enlarging the effects on cancer prevention.

Objectives : This study aims to investigate the effectiveness of an internet-based anger management program for school-aged children. Methods : Forty-eight elementary school students took part in an anger management training program; subsequently, participants, their parents, and their teachers answered questionnaires assessing the participants' anger, aggressiveness, and other emotional/behavioral problems, pre- and post-training. Results : At the post-training self-assessment, the participants showed significant reductions in their "anger-out" tendencies and physical aggressiveness. In addition, the effects of the program on "anger-out" tendencies, aggressiveness, anger and peer relational problem were found to be more significant in participants who reported depressive symptoms. Teachers rated the participants' peer-relational problems as having decreased after the training. Conclusion : The proposed internet-based anger management program had a significant effect on the school-aged children's abilities to control their anger.
