Objective In Korea, online board games, such as "flower cards," are played using virtual money. In contrast, Internet-based gambling (ibGambling) concerns the use of real money to gamble online. We hypothesized that online board gamers using virtual money show less risky behaviors than do gamblers who use real money, and that, in regard to psychological aspects, online board gamers are less depressed and more introverted than online gamblers are. Methods For this study, 100 online board gamers, 100 ibGamblers, 100 offline gamblers (offGamblers), and 100 age- and sex-matched healthy controls were recruited by an online research company. Gambling behavior and self-efficacy were assessed using the Korean Gambling Behavior Scale-high/low factors (KGBS-H/L) and the Gambling Abstinence Self-efficacy Scale (GASS). Additionally, introversion, depression, and mania tendency were assessed. Results Online board gamers had good intentions gaming, as evidenced by their higher KGBS-L scores than ibGamblers and offGamblers, and they showed less risky behaviors, as evidenced by their lower KGBS-H scores than offGamblers. Additionally, online board gamers were less introverted than ibGamblers and less depressed than offGamblers. Conclusion Online board gaming could be a gateway to the world of gambling (ibGambling or OffGambling). However, the higher tendency of online board gamers to engage in good intentioned gaming could help prevent online board gaming from progressing to online or offline gambling.

The purpose of this study was to develop a nutrition education website for children, especially those around the 4th-6th grade levels. Among the already existing websites providing nutritional information for children, 7 websites with comparable amounts of information were evaluated in terms of their topics, credibility, content, ease of use, and aesthetics. In addition, a survey was conducted to assess the need for nutrition information among 305 elementary students. The food pyramid was the topic offered most often on those websites. Information on nutrients, digestion, food safety, nutrition labeling, and healthy eating habits were available on the websites. Some of those websites also provided games or quizzes to attract the children's interest. However, seine of the websites did not give any information on the person responsible for providing the information, which is most important in determining the credibility of the website. Other problems were that some information was too difficult for children, and some of the websites did not provide a way to search for information. According to the survey results, the topics that children wanted to know about were‘desirable weight’,‘cooking’,‘correct food choice’,‘weight control method’,‘calories consumed during exercise’, but, they did not have a high interest in‘asking questions’‘books with nutrition messages’,‘under weight’,‘negative effect of weight control’and‘helping hungry children’. Based on these results, we developed a new nutrition education web-site, ifood’(http: //1 ifood.or.kr). We focused on helping children develop healthy eating habits by providing information which is easy and practical for children. However, we neither included the program to assess their dietary intake, nor provided entertaining background sounds, which children like. Also, the game section is composed mainly of quizzes. Therefore, we need to further develop exciting games to teach nutrition to children. In the near future, the newly developed website should be evaluated by children regarding understandability and coverage of the contents as well as usability and design, and then revised to improve the educational effect.

Large-scale natural disasters such as typhoon and localized torrential downpour cause widespread human and property damages. Recently, management systems using GIS are being developed to manage such disasters from various angles. Integrated disaster management encompasses diverse areas such as prediction through the computation of disaster information and field support for response. The development of disaster information systems must also consider the installation of various computation modules. Furthermore, GIS is generally included for realistic description of the field situation and for spatial operations. This study aims to develop the core module of a visualization platform for the 3D GIS services of integrated disaster information using Unity engine This system will enable integrated disaster management from various angles, encompassing disaster prevention experts, field support personnel, and citizens.
