This study investigates the relationship between controllability, severity, unrealistic optimism and risk perception of risk factors related to location - based SNS services for smartphone users. For this purpose, I surveyed university students who had experience using location - based SNS service. The main results are as follows. First, controllability has a statistically significant effect on unrealistic optimism. Second, Severity had a statistically significant negative impact on unrealistic optimism. Third, Controllability did not have a statistically significant effect on risk perception, Fourth, Severity did not have a statistically significant effect on perceived risk. Fifth, Unrealistic optimism had a statistically significant negative impact on perception of risk. The results of this study will contribute to the prevention of privacy incidents and the protection of smartphone users by using location - based SNS service. On the one hand, future research will need to look at the relationship between unrealistic optimism and risk prevention or coping behavior.

This study aimed to explore how the AIDS knowledge, self esteem, sense of control and optimistic bias affect condom use among male college students. The survey was done among 323 male students within a university in B city and analyzed according to descriptive statistics, ANOVA, Pearson correlation, and multiple regression analysis. The students had optimistic bias regarding AIDS, and the scores on the AIDS knowledge, self esteem, and sense of control were all rated high. Self esteem and sense of control, sense of control and optimistic bias, sense of control and condom use on sexual intercourse with steady sex partner, condom use on with casual sex partners and with steady sex partner showed significant positive correlation. Self esteem and sense of control were predictors of condom use on sexual intercourse with steady sex partner. Additional studies among various groups should be followed to identify the relationship between variables and condom use.

This study was conducted to identify the correlation between dental hygiene students' overdependence on smartphones, sleep deprivation, and self-control, and factors influencing self-control. 267 college students in the department of dental hygiene located in the Chungcheong area were surveyed and analyzed. Smartphone overdependence was positively correlated with sleep deprivation and smartphone overdependence was negative correlated with self-control. The sleep deprivation was negative correlated with self-control. Factors affected to self-control were problematic results and sleep deprivation. Therefore, it is necessary to develop education and programs that can increase the self-control of dental hygiene students and to prepare measures to prevent sleep problems and overdependence on smartphone.

The purpose of this study was to construct and test a structural equation model for college student's gambling behavior. A structured questionnaire was completed by 246 college students to analyze the relationships between perspective factors(irrational gambling belief), psychological factors(depression, anxiety), social factors(parental monitoring, parental support, friend support), self-control and gambling behavior. The moderating effects of gender, friends and family's gambling behaviors were examined. The data were analyzed using SPSS 21,0 and AMOS 20.0 programs. Self-control and psychological factors directly affected the college student's gambling behavior, while perspective factors and social factors affected it indirectly. The model fit indices of the modified model were suitable for the recommended levels. The overall study findings suggest the need to develop a gambling prevention program for college students that reinforces self-control, parental monitoring and support, and friend support while reducing irrational gambling belief, depression, and anxiety. An approach that considers gender and a development of a group counseling program for family or friends are also required.

The purpose of the study is to verify whether literature therapy program for prevention of smartphone addiction is effective for adolescents. The subjects of this study were 150 students of J City, K middle school. After completing the program, they were conducted post-test for both the experimental and control groups. The study found that the program was effective in mitigating smartphone addiction but not in reducing the directed life problem. It was also found to be effective in reducing tolerance and loss of control and problems of withdrawal and emotional experience. The study suggests that institutional arrangements are needed for linking with related organizations in the region because it is difficult to effectively prevent the increasing problem of smartphone addiction unless an adolescents program for youth is linked to the school. Therefore, it is necessary to conduct parent education for prevention of smartphone addiction in computer curriculum of school subjects.

This study was carried out in April, 2018, and the experimental group and the control group were 12 students in each of the first grade of middle school in S city and A city. As a result, the level of perceptions of school violence in the experimental group was 14.50 in pre-test, 11.83 in post-test, and 9.33 in average rank. The level of perceptions of school violence in the control group was 14.25 in pre test, 13.83 in post-test, and 15.67 in average rank. The Mann- Whitney U test between the two groups showed statistically significant indicating that school violence prevention programs are effective. The program has been satisfaction in the experimental group and the total average is very high as 4.71 out of five points, in particular the highest satisfaction with 'teacher's class progress'.

Purpose: The purpose of this study was to investigate the effects of nutrient intake and dietary diversity score (DDS) on osteoporosis after controlling for sex, age, socioeconomic level, drinking, smoking, physical activity, and body mass index (BMI) as mediators using the 2015-2017 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods: This study was focused on the age group of 50s and older by using the 2015-2017 KNHANES data. Subjects diagnosed with osteoporosis were classified as the osteoporosis group, and the other subjects were classified as the normal group. Logistic regression was used to assess the association between nutrient intake and DDS after controlling for mediators. Results: The risk of osteoporosis was 2.38 times lower in the 50-65 age group than in the 75 years and older group. The mediators affecting the incidence of osteoporosis by age group were sex, age, household income level, and education level in the 50-64 age group; sex, education level, drinking, and BMI in the 65-74 age group; and sex, age, current smoking, drinking, BMI, and energy intake in the 75 years and older group. The effect of nutrient intake on osteoporosis, with the exception of vitamin B1, was fully mediated by these mediators. The effect of vitamin B1 was partially mediated by mediators in the age group of 65-74 years, and vitamin B1 was effective for preventing the risk of osteoporosis by 25% when consumed over EAR. The effect of DDS was partially mediated in the age group of 75 years and older, and DDS of 2 or less increased the risk of osteoporosis by 2.59 times. Conclusion: As a result of this study, it is necessary to recommend the balanced intake of various foods including grains, meat·fish·legumes, vegetables, fruits, and dairy products as dietary guidelines for the prevention of osteoporosis and promotion of bone health in the elderly.
