  • Many researches have been done in insurance fraud as the amount and frequency of insurance fraud have been increasing continuously. In particular, the development of insurance fraud detection system using large database management techniques including data mining or link analysis based on visual method have been the main research topic in insurance fraud. However, this kinds of detection system were very ineffective to find unintentional insurance fraud happened by accident even though it was so good to find intentional and organized crime insurance fraud. Therefore, this research suggests insurance fraud as an ethical decision making and applies TPB(Theory of Planned Behavior) for the finding of reasons and prevention strategies of unintentional insurance fraud happened by accident. The results of research show that TPB is very appropriate model to explain the behavior of insurance fraud and that insurance agents force to do insurance fraud as affecting perceived behavior control. Therefore, education and pubic relations for insurance fraud are very effective for preventing insurance fraud and developing insurance service industry.

  • The objective of this study was to investigate the perception of walking environment and use of neighborhood facilities of rural female elderly, who are the most susceptible to ambulatory problems. The study showed that parks, senior centers and hospitals were among the most frequently used neighborhood facilities by rural female elderly, while bus stations and senior centers were recognized as the closest facilities. Frequency of use was higher for paid sports facilities rather than parks. Hospitals and health centers were facilities that were desired to be in close proximity. Social support, self-efficacy, and attitude were the factors that affected walking environment. Street trees, accessibility to parks, and street lights were factors that showed a positive relationship with total time of walking activity while perceived crime rate and slopes were perceived as environmental challenges for groups that walked under 150 minutes per week. One factor that negatively affected walking was the lack of sidewalks on streets. Providing parks and walking trails within neighborhood, pleasant walking environments, and safe sidewalks would contribute to improved perception of neighborhood and walking of older rural women.

  • This study focused on the people harmed by violent offenders, especially by rubberies. Trends capture changes in victimization rates overtime, while patterns indicate connections between the attributes of victims and the frequency with which they are targeted. Data from the UCR and the NCVS indicate that many types of victimization are taking place less frequently since their peak years in the late 1980s and early 1990s. Cumulative risks indicate the odds of being victimized over the course of a lifetime. Differential risks underscore which categories of people are victimized more often than others.

  • Objectives: While cinema is regarded in the contemporary popular leisure activities, the presentation smoking scenes in films has not been fully studied. We investigated Korean box-office hit movies by using content analysis. Methods: We sampled fifty-one hit films played in Korean cinemas during the period 2000-2013. Here, a hit film is defined as a movie viewed by at least 5,000,000 audiences. Results: We found that 78.1% of the Korean hit films contained smoking scenes, whereas only 15.6% of the American hit films were so. Films with the more frequent number of smoking scenes could be lined up in the order of crime, thriller, and action genres (p<.05). Smoking actors were leading roles, hence attractive characters appealing to the audience. Moreover, the smoking rate of female characters in the films was determined to be 3.66 times greater than the actual smoking rate of females in reality. Conclusions: Smoking scenes are likely to affect the audiences' cognitive priming and/or social learning with respect to smoking. Therefore, it would be necessary to set a restriction standard to the frequency of smoking scenes to appear Korean films, and to consider it as an important factor in the assigning a screening grade to such films.

  • Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to a decrease in face-to-face classes worldwide, affecting the mental health of children and their parents. The global pandemic has increased children's overall use of electronic media. This study analyzed the effect of children's screen time on problematic behaviors during the COVID-19 pandemic. Methods: A total of 186 parents from Suwon, South Korea, were recruited to participate in an online survey. The mean age of the children was 10.14 years old, and 44.1% were females. The questionnaire included questions on children's screen time, problematic behaviors, and parental stress. Children's behavioral problems were evaluated using the Behavior Problem Index, whereas the Parental Stress Scale was used to estimate parental stress. Results: The mean smartphone usage frequency of the children was 5.35 days per week, and the mean smartphone screen time was 3.52 hours per day. Smartphone screen time (Z=4.49, p<0.001) and usage frequency (Z=2.75, p=0.006) were significantly correlated with children's behavioral problem scores. The indirect effect of parental stress on this relationship was also statistically significant (p=0.049, p=0.045, respectively). Conclusion: This study suggests that children's smartphone screen time has affected problematic behaviors during the COVID-19 pandemic. Furthermore, parental stress is related to the relationship between children's screen time and problematic behaviors.

  • The present study examined the accuracy of polygraph tests through two types of statistical methods with unknown ground truth. One method evaluated the accuracy based on the rates of agreements between polygraph test results of crime suspects and prosecutors' indictment decisions for them. Those crime suspects were tested with polygraph by the Prosecutors' Office of the Republic of Korea between 2000 and 2004. The other method estimated the accuracy by using the latent class analysis based on the frequency distributions of the polygraph results and indictments during 2006. Excluding cases that were 'inconclusive' on the polygraph test, the study showed that the accuracy of the polygraph tests is .914 (SE=.004) for the 2000-2004 data, and .885 (SE=.021) for the 2006 data. With the inclusion of 'inconclusive' cases in the 2006 data, the results from the latent class analysis showed the accuracy in the range between .707 and .734 (SE=.027~.031), with false positives between .078 and .087 (SE=.019~.023), and false negatives between .029 and .078 (SE=.010~.023). The probability that the polygraph test correctly classifies subjects appeared to be in the range between .912 and .925 (SE=.013-.016) for those who lie, and in the range between .867 to .955 (SE=.011-.040) for those who tell the truth.
