The purpose of this study is to verify the path of the motivation, the flow, and problem gambling and intervention points. To this end, we verified the mediation effect of the motivation of the users outside sales offices influences the problem gambling through a flow and the moderated mediation effect of the frequency of the use of a bicycle racing tracks in that process. A total of 411 cases were analyzed using surveys conducted for one day on a weekday and weekend (September 13th and 15th 2018) for adults using an outside sales office in Jangan. According to the analysis, the causality of gambling by gambling motivation(amusement, excitement, avoidance, society, money) showed its effect positively by mediating the flow. The adjusted effect of the frequency of the use on the intermediary effect of the motivation ${\rightarrow}$ flow ${\rightarrow}$ problem gambling behavior, which is the main concern of this study, was found to be statistically significant. More specifically, the effect of adjusting the frequency of the use was statistically significant in both paths: motivation/flow and flow/problem gambling. It was also shown that, in the model with excitement, avoidance and social motivation, the adjustment of the frequency was only significant in the causal relationship between the flow and problem gambling. Based on these findings, this study made clinical and policy suggestions for intervention for gamblers and user protection regulations.

This study investigates the effects of availability and accessibility on an individual's risk of developing a gambling problem. A total of 24 off-track betting facilities located in 12 districts of Seoul were examined in an effort to identify any association between their presence and citizens' gambling habits. Study participants included 1,490 online recruits residing in Seoul who participated in gambling activities in the 12 months prior to the study. To examine the differences in addiction rates and gambling frequency, a survey of demographics, gambling addictions, and gambling frequency divided the participants into two groups: those who resided in a district where off-track betting facilities were available, and those who resided elsewhere. Analysis results indicate that gambling frequency and addiction rates were significantly higher among participants residing in a district where off-track betting terminals are available. Additional analysis was performed with participants who mainly gambled on horse racing, with results similar to the previous analysis-significantly higher rates of gambling addiction and frequency were observed among participants residing in close proximity to off-track betting facilities.

This study examined the effects of irrational beliefs, impulsivity and happiness on problem gambling of Korean and Australian college students. Data were collected from 581 college students of Korea, and 100 college students of Cairns of Australia. As a result, The overall mean of the CPGI was significantly different between Koreans and Australians (t=-29.828**). As for classification of gamblers by sub-type of CPGI, the number of problem gamblers in Australians was 7.0% compared to 5.3% for Koreans, showing a significant difference. In Multiple regression analyses, irrational beliefs, happiness, and the frequency of gambling significantly predicted problem gambling of Koreans (R2 = 0.175 F = 23.441, p < .001). On the other hands, irrational beliefs and the frequency of gambling significantly predicted problem gambling of Australians(R2 = 0.368, F = 10.844, p < .001). Through this study, it was found that the factors affecting the problem gamblers of Korean and Australian are different. It is required to continue further education on gambling among young adults of Korea and Australia.

This paper discusses how we developed an index for measuring problem gambling severity and determined the cutoff score for identifying addicts. This index uses fewer items than the current index and will be particularly useful for telephone surveys. We selected four items among the nine Korean Problem Gambling Severity Index (K-PGSI) items based on our statistical analysis of a survey of 501 gamblers. We applied this four-item index to a survey of 1,584 adults. The analysis of this survey proved the validity of the reduced index. The sensitivity and specificity of this index was 1.00 and 0.99 respectively, showing again the usefulness of this scale.

This study was attempted to identify the convergence factors that affected the gambling abstinence self-efficacy among college students using gambling. The participants were 134 students with gambling experience at two universities in C city and G city. The results of this study are as follows. Stress(r=-.314, p<.001) and gambling change motivation(r=.272, p=.001) showed a significant correlation with gambling abstinence self-efficacy in correlation analysis. The greatest influence on gambling abstinence self-efficacy in multiple regression analysis was identified in order of stress(${\beta}=-.29$, p<.001), gambling change motivation (${\beta}=.25$, p=.003). The results of this study suggest that a gambling prevention education program which can manage stress and strengthen the gambling change motivation of college students using gambling is needed to improve the gambling abstinence self-efficacy.

This study was the first attempt to investigate which factors influence problem gambling among out-of-school adolescents in South Korea. Using data from the 2015 Survey on Youth Gambling Problems, this study examined the influences of personal characteristics and betting games on problem gambling among out-of-school adolescents. Regression analyses of personal characteristics on problem gambling showed that being male adolescents, having more allowance, living without parents/guardians, or belonging to probation was associated with higher likelihood of doing problem gambling among out-of-school adolescents. Also, regression analyses of betting games on problem gambling revealed that doing betting games more frequently, doing betting games more time, or spending more money on betting games was associated with higher likelihood of doing problem gambling among out-of-school adolescents. Based on the findings, this study suggested practice and policy implications for addressing problem gambling among out-of-school adolescents.

In this paper, we propose an effective method to block illegal gambling advertisement on social media. With the increase of smartphone and internet usage, users can easily access various information while sharing information such as text and video with a large number of others. In addition, illegal sports gambling advertisements are also continue to be transmitted on SNS. To avoid most surveillance networks, users are easily exposed to illegal sports gambling advertisement images by including phrases in the images that indicate illegal sports gambling advertisements. In order to cope with these problems, we proposed a method to actively block illegal sports gambling advertisements in a way different from the conventional passive methods. In this paper, we select words frequently used for illegal sports gambling, classifies them into three groups according to their importance, calculate WF for each word using weighted formula by degree of relevance and frequency, and then sum the WF of the words in the image. Blocking, warning, and passing were determined by cv, the total of WF. Experimenting with the proposed method, 193 out of 200 experimental images were correctly judged with 96.5% accuracy, and even though 7 images were illegal sports gambling advertisements. Further research is needed to block 3.5% of illegal sports betting ads that cannot be blocked in the future.

The purpose of the paper Is to discuss and estimate early Popper's theory of probability, which is presented in his book, The Logic of of Scientific Discovery. For this, Von Mises' frequency theory shall be discussed in detail, which is regarded as the most systematic and sophisticated frequency theory among others. Von Mises developed his theory to response to various critical questions such as how finite and empirical collectives can be represented in terms of infinite and mathematical collectives, and how the axiom of randomness can be mathematically formulated. But his theory still has another difficulty, which is concerned with the inconsistency between the axiom of convergence and the axiom of randomness. Defending the objective theory of probability, Popper tries to present his own frequency theory, solving the difficulty. He suggests that the axiom of convergence be given up and that the axiom of randomness be modified to solve Von Mises' problem. That is, Popper introduces the notion of ordinal selection and neighborhood selection to modify the axiom of randomness. He then shows that Bernoulli's theorem is derived from the modified axiom. Consequently, it can be said that Popper solves the problem of inconsistency which is regarded as crucial to Von Mises' theory. However, Popper's suggestion has not drawn much attention. I think it is because his theory seems anti-intuitive in the sense that it gives up the axiom of convergence which is the basis of the frequency theory So for more persuasive frequency theory, it is necessary to formulate the axiom of randomness to be consistent with the axiom of convergence.
