인공지능 기술의 발전에 따라 산업, 교육, 게임, 의료, 국방, 교통 등에서 여러 가지 방면으로 활용되어가고 있다. 하지만 인공지능을 게임에 접목해 게임 내에서 사람보다 월등한 성적을 낼 수 있다는 것이다. 과거에는 메모리 변조, 패킷 변조 등의 공정한 플레이 규정을 파괴하는 프로그램을 사용하였다면 현재에는 딥러닝을 통해 학습된 게임 알고리즘은 이제까지의 프로그램과는 다르므로 게임 인공지능 산업의 개선방안을 제안하고자 한다.

The qualitative and quantitative analysis of MDMA and MDA in hair samples by GC/MS were reported. Hairs were collected from subjects aged 22-37 years, who were suspected of abusing MDMA. After washing with methanol, hair samples were cut into small pieces, extracted with methanol containing 1 percent hydrochloric acid for 20th, and the solution was evaporated. MDMA or MDA in the extract were determined by GC/MS using selected ion monitoring after derivatization with trifluoroacetic anhydride. (omitted)

The Purpose of this study is to empirically examine the factors that affect the consumer's buying behavior under the e-commerce environment. In order to achieve this goal, vendor characteristics, securities of transaction, concern for privacy, shopping orientation and perceived channel utilities were used as independent variables. Findings of study indicated that the concerns for abusing individual information, perceived securities of transaction, consumer's recreational orientation, consumer's convenience orientation, perceived distribution channel are the robust predictors of buying behavior of internet users.

CEP(Complex Event Processing) is a technique to find complex event pattern in a massive information system. Based on CEP technique, an abuse pattern monitoring method has been developed to provide an real-time detection. In the method, the events occurred by game-play are observed to be against the rules using CEP. User abuse patterns are pre-registered in CEP engine. And CEP engine monitors user abuse after aggregating the game data transferred by game logging server. This article provides the performance analysis results of the abuse pattern monitoring method using real game DB. We results that the method proposed in previous study is effective to monitor abusing users.

GUMF (Global User Management Framework) that is proposed in this research can be applied to next generation network such as BcN (Broadband convergence Network), it is QoS guaranteed security framework for user that can solve present Internet's security vulnerability. GUMF offers anonymity for user of service and use the user's real-name or ID for management of service and it is technology that can realize secure QoS. GUMF needs management framework, UMS (User Management System), VNC (Virtual Network Controller) etc. UMS consists of root UMS in country dimension and Local UMS in each site dimension. VNC is network security equipment including VPN, QoS and security functions etc., and it achieves the QoSS (Quality of Security Service) and CLS(Communication Level Switching) functions. GUMF can offer safety in bandwidth consumption attacks such as worm propagation and DoS/DDoS, IP spoofing attack, and current most attack such as abusing of private information because it can offer the different QoS guaranteed network according to user's grades. User's grades are divided by 4 levels from Level 0 to Level 3, and user's security service level is decided according to level of the private information. Level 3 users that offer bio-information can receive secure network service that privacy is guaranteed. Therefore, GUMF that is proposed in this research can offer profit model to ISP and NSP, and can be utilized by strategy for secure u-Korea realization.

The automatic payment process of mobile phone micropayment system has not checked user's authentication. That is the structural vulnerability of mobile phone micropayment system. The malicious contents provider can cheat users and payment gateway through abusing the structural vulnerability. The payment gateway applies standard payment module after August, 2012 in order to solve the problem. But the standard payment module also has the vulnerability that makes damage of users. So the purpose of this paper is to suggest efficient improvement of standard payment module for user protection.

The goal of this study is twofold: (1) to identify how well the predictors of family resilience using selected ENRICH subscales measure couple resilience of spouse abusing couples; (2) to verify how predictors of family resilience differentiate abusive partners from non-abusive partners through discriminant analysis. The results show that nonviolent couples have significantly higher scores of family resilience factors than violence experienced couples. The accuracy of discriminant analysis was as high as 85.7% for non-violent couples and 85.4% for violence experienced couples. Whereas collaborative problem solving and couple's flexibility had the highest discriminant power, socioeconomic resources and transcendence and spirituality had little contributed. In addition, this study shows that predictors of family resilience have high discriminant power for distinguishing violent groups from non-violent groups. The results of this study can be clinically utilized in identifying violent groups and designing couple education programs. Based on these results, the recommendations for the future research in this area were discussed.

The author investigated the zinc concentrations in sera of 110 methamphetaimine abusers (male 87, female 23) and of 41 healthy official workers(male 29, female 12) using inductively coupled plasma emission spectrometer. The serum zinc concentrations were analysed according to hepatitis C virus antibody(Anti HCV), hepatitis B surface antigen(HBsAg) and alanine aminotransferase(ALT) value in both groups. The analytical results were obtained as follows 1. The mean zinc concentration of MAP abuser group($298.5{\pm]246.9{\mu}g/100ml$) was 2.5 times higher than that of control group($118.8{\pm}25.4{\mu}g/100ml$). 2. The distributions of zinc concentration in both groups were skewed pattern. 3. The zinc concentrations were higher in Anti HCV-positive group and abnormal ALT value group than Anti HCV-negative group and normal ALT value group. But HBs-Ag positive group had lower zinc concentration than HBs-Ag negative group. 4. The number of anti HCV-positive subjects was increased and the zinc concentrations were decreasd in proportion to the abusing duration of MAP.

This paper describes an optimal design of electric snow melting mat on vulnerable walk zone. In order to design an optimal electric power of snow melting mat and protect pedestrians with a nonslip mat, with considering protection of environmental pollution from abusing of the de-icing salts added calcium chloride. We analyzed nine snow melting mats through verification experiment in the condition of $-5^{\circ}C$, depending on three different kinds of heating material, electric heating cable, carbon heating film and carbon textile film. As a consequence, the $150W/m^2$ carbon textile film mat for snow melting was identified as an optimal power input and functional performance for pedestrians' safety on vulnerable walk zone. It is expected that the $150W/m^2$ carbon textile film mat would be useful to reduce slip down accidents by human error.
