This study identifies and tracks changes gender differences in adolescent users' problematic online behavior. This study used Korea Youth Panel Survey (KYPS), which has tracked respondents over 7 years, with self-control theory and social learning theory applied as a theoretical framework. The model included individual-level variables such as self-control and respondent's experience of problematic behavior (offline), as well as socialization variables such as the number close friends who engaged in problematic offline behavior, parent-child relationships, and parental monitoring. Dependent variables included problematic online behavior, unauthorized ID use (ID theft) and cyberbullying (cursing/insulting someone in a chat room or on a bulletin board). Control variables consisted of academic performance, time spent on a computer, monthly household income, and father's educational attainment. Random and fixed effects models were performed by gender. Results supported self-control theory even for the within-level analysis (fixed effects models) regardless of gender, while social learning theory was partially supported. Only peer effects were found significant (except for unauthorized ID use) among girls. Year dummy variables showed significant negative associations; however, academic performance and time spent using computers were significant in some models. Father's educational attainment and monthly household income were found insignificant, even in the random effects models. We also discuss implications and suggestions for future research and policy makers.

Purpose: The purpose of this study was to identify effects of attitude, subjective norm, and perceived behavior control toward Human Papillomavirus (HPV) on HPV vaccination intention in female high school students. Methods: Subjects of this study were female students aged 16 to 17 years, the optimal age group of HPV vaccination, arbitrarily selected from three high schools in B city. A total of 140 students agreed to participate in this study. Data were analyzed using descriptive statistics, t-test, ANOVA, correlation, and stepwise multiple regression. Results: Attitude, subjective norm, and perceived behavior control toward HPV were factors influencing HPV vaccination intention of subjects. Perceived behavior control toward HPV vaccination was the most influential factor. These factors accounted for 49% of HPV vaccination intention. Conclusion: These results suggest a need to increase perceived behavior control to increase HPV vaccination intention. The government needs to establish a national policy system such as financial support for HPV vaccines and free vaccinations so that students are aware that HPV vaccines can be easily inoculated.

Purpose: The purpose of this study was to compare self-care behavior, diabetes-related stress and stress coping style among 3 blood glucose control groups (good, inadequate, and poor blood glucose control groups). Methods: Participants were 102 type 2 diabetic patients (good group: 41, inadequate group: 31, poor group: 30). Data were collected from Feb 19 to Mar 24, 2010 and were analyzed using Chi-square, Fisher's exact test and ANCOVA with SPSS/WIN 12.0. Results: Using ANCOVA with frequency of admission, and illness duration as covariates, significant differences were found among the 3 groups in self-care behavior (total score) and the exercise subscale. Using ANCOVA significant differences were found among 3 groups in diabetes-related stress (total score), emotional burden subscale and regimen distress subscale. Using ANCOVA no difference in stress coping was found among the 3 groups, but there was a significant difference in the problem-oriented coping subscale. Conclusions: Self-care behavior, diabetes-related stress, and stress coping style are factors influencing blood glucose control. The results of this study suggest that for improving blood glucose control, self care education program focused on diet and exercise in addition to stress management program for promoting problem oriented coping capability are recommended.

Purpose: This study was done to identify factors based on the theory of planned behavior that predict smoking cessation in elderly smokers following a stroke. Method: Between March and May 2013, data related to intention, attitude toward the behavior, subjective norm, and perceived behavioral control, were collected through questionnaire from 223 elders who smoked and who had a stroke. Data analysis was performed using PASW (SPSS) 18.0 program, and included t-test, one-way ANOVA, Pearson correlation coefficients, and multiple stepwise liner regression analysis. Results: Results showed a positive correlation between intention and attitude toward the behavior (r=.494, p<.001), subjective norm (r=.390, p<.001), and perceived behavioral control (r=.189, p=.005). These variables such as perceived behavior control, subjective norm, number of cigarettes per day, and usefulness of quitting smoking explained 50% of intention to quit smoking. Conclusion: The results of this study indicate that there is a need to develop smoking cessation nursing strategies for elderly smokers following a stroke in order to provide effective counseling on subjective norm and perceived behavioral control.

This study has the goal to modify ‘Investigating and Evaluating Environmental Issues and Actions’(IEEIA) instruction in the sense of Korean ecological sociocultural characteristics and ‘ecology and environment' curriculum and to assess the effects of modified IEEIA instruction on responsible environmental behavior and associated variables in high school student. A modified pre- and post-test nonequivalent control group design was utilized with 4 intact classes from J-high school at Seo-cheon, Chungcheongnamdo. Pre- and post-test data were collected on the following variables: responsible environmental behavior, knowledge of and skill in using environmental actions strategies, in-depth knowledge about issues, and locus of control. Analysis of t-test was used to compare pretest with posttest means of treatment group and control group. In treatment group, statistically significant differences between pretest and posttest were found with all variables. The treatment was found to be more effective than the control in increasing the variables of responsible environmental behavior, knowledge of and skill in using environmental actions strategies, and locus of control.

In order to obtain basic data for a health promotion program of hair dressers, the health promoting behavior of some hair dressers was assessed with the related factors such as general characteristics and cognitive-perceptual factors. The subjects were 245 hair dressers working at beauty shops having at least two hair dressers. The data was collected by a questionnaire from October 14 to October 20, 2001. The results were as follows： 1. The mean score of health promoting behavior conducted by the hair dressers was 31.17 out of 50.00 in total score. 2. The score of the health promoting behavior was statistically different according to marriage, on-duty hours, holidays, satisfaction in the job, perceived health status, perceived fatigue, health concept, and self-efficacy (p＜.05), while it was not statistically different according to gender, religious faith, residence, eduation, economic levels, career in the job, average income, medical care insurance, employment insurance, control of fortuity, and control over other persons. 3. The health promoting behaviors in the hair dressers showed positive correlation with self-efficacy and internal control, while it showed negative correlation with control over other people, control of fortuity, health concept, and perceived fatigue. 4. The Regression analysis results of the questionnaire showed that perceived fatigue, health concept and office hours were significant factors but the age, the fact of being single or couple, position at the job, holidays, satisfaction of the job, self-control and stresses from other people and self-efficiency appeared insignificant. In conclusion, the hair dressers with less perceived fatigue and better cognitive health concept and short duty hours showed better health promoting behavior. So, In order to conduct health promoting behaviors of hair dressers, the method will need to control of working time and perceived fatigue.

The purpose of this study was to examine the effects of sensory integration therapy (SIT) on sensory' motor development and adaptive behavior of cerebral palsy children. The design of this study was quasi experiments with a non-equivalent pre- and post-test control design. Subjects of the study were arbitrarily chosen based on predetermined selection criteria among the cerebral palsy children who were treated as out-patients at two rehabilitation hospitals one in Seoul, and the other in Kyunggi-do. The study was conducted between early April and late July in 2000. Fifteen children were in the experimental group and eleven in the control group. The allocation was done based on ease of experimental treatment. A five-step SIT program was devised from a combination of SIT programs suggested by Ayres(1985) and Finks(1989), and an author-designed SIT program for cerebral palsy children. The experimental group was subjected to 20 to 30 minutes of SIT per session. two sessions a week for ten -week period. The effects of SIT were measured with respect to 9 sub-areas that can be administered to cerebral palsy children out of a total of 17 sub-areas in the Southern California Sensory Integration Test (SCSIT) developed by Ayres (1980). In addition. the scale developed by Russell (1993) for Gross Motor Function Measure (GMFM). and Perception Motor Development Test developed by 中司利一 et al.(1987) were also applied. Adaptive behavior was analyzed using guidelines in two unpublished documents - School-Age Checklist for Occupational Therapy by the Wakefield Occupational Therapy Associates, and the OTA-Watertown Clinical Assessment by the Watertown Occupational Therapy Associates-, and an author-developed Adaptive Behavior Checklist. Collected data were statistically analyzed by SPSS PC for chi square test, Mann-Whitney test, Wilcoxon signed rank test, and paired t-test. The results were as follows: 1. In sensory development, the experimental group exhibited a score increase compared to the control group, but the difference was not statistically significant, Although the experimental group showed improvements in all. 9 sub-areas compared to the control group, only right-left discrimination exhibited statistically significant change. 2. In gross motor development, the experimental group showed improvements in score compared to the control group, but it was not statistically significant. In fine motor development, the experimental group exhibited statistically significant improvements compared to the control group. In sub-area analysis, figure synthesis showed positive change. 3. In adaptive behavior development, post-experimental adaptive behavior scores were higher compared to pre-experimental scores with statistical significance. Furthermore, sub-areas emotional behavior, perception behavior, gross-fine motor function, oral-respiration function, motor behavior, motor planning, and adaptive response exhibited higher scores after SIT. In conclusion SIT was found to be partially effective in sensory and fine motor development, effective in all adaptive behavior areas, and not effective in gross motor development. Thus, this study has shown that SIT is an effective intervention for sensory development, fine motor development, and adaptive behavior for cerebral palsy children. But, for the effectiveness of SIT on gross motor development, further studies employing longer-time experiments are recommended.

This study was carried out to examine the effects of school safety education on the safety behavior among elementary school students. Sixty-two 4th grade students were sampled from an elementary school in Pohang city and divided into one experimental group and one control group. The safety education has been provided to the experimental group for 4 weeks The data were collected before, just after, and 8 weeks after the education. In the pre-test, the general characteristics and safety behavior between two groups were measured. The experimental group was given school safety education twice a week for 4weeks. They also filled out the self behavior check list. In the post-test and follow up-test safety behavior was collected. The data analysis was done using $X^2$-test. t-test. Repeated measures ANOVA, analysis of simple main effect and time contrast methods, they were processed with an SPSS Win 9.0/pc. The results of this study are summarized as follows: 1) There were no differences between experimental group and control group on the general characteristics and safety behavior in the pre-test. 2) The hypothesis: 'The experimental group which was given school safety education will show higher scores on safety behavior than the control group which was not given this was supported(F=6.43 p=0.01). 3) The subhypothesis 1 : 'The scores on the indoor safety behavior of the experimental group which was given school safety education will show higher than those of the control group which were given this was supported(F=3.59 p=0.03). 4) The subhypothesis 2 : 'The scores on the outdoor safety behavior of the experimental group which was given, school safety education will show higher than those of the control group which was not given this was supported(F=5.70 p =0.00). In consequence, the experimental group which was given school safety education scored higher on safety behavior than the control group. Therefore, school safety education should continue to encourage safety behavior among elementary school students.

This paper considers overload control in telecommunication networks. Markov-modulated Bernoulli process ( MMBP ) has been extensively used to model bursty traffics with time-correlation. Thus, we investigate the transient behavior of the queueing system MMBP/D/l/K queue with two thresholds. The model is analyzed recursively by using the generating function method. We obtain the transient queue length distribution and waiting time distribution at an arbitrary time. The transient behavior of the queueing system helps observing the temporary system behavior.
