The current study investigated whether individual variation in motivational activation would predict the drug-use and interacts with discrete emotions to influence the responses to anti-drug advertisements. Motivational activation tendency indicates an individual's level to approach life-sustaining elements and defend life-threatening stimuli. Discrete emotion represents joy, sadness, and fear elicited by the advertisements. The experiment proceeded using both self-reports and physiological responses with 80 subjects. Results showed that approach motivation activation can be a target for anti-drug advertisements and in order to target individuals higher in approach activation, it is necessary to use the appeal type to elicit positive emotions such as joy.

The positive relationship between older driver's mobility and life satisfaction is well established(e. g., Collins, 2008). The present study showed that this relationship can be changed by older drivers' motivation, aspects of mobility, and affectivity. Specifically, this study examined whether aspects of mobility(amount of driving measured by travel distance and time: 'AD' or amount of driving for social activity: 'DSA') can be differed as a function of approach/avoidance motivation(measured by BIS/BAS scale, Carver et al., 1994) and positive/negative affect(PA/NA; measured by SPANAS, Diener et al., 2009) mediate the relationship between the aspects of mobility and life satisfaction(measured by SWLS, Diener et al., 1985). Self-reported scores of the variables of 132 older drivers(ages of over 65) were analyzed using correlation analysis and path analysis. The results can be summarized as followings. First, the older driver's BAS was found to be positively related to DSA, but BIS was negatively to AD. In particular, DSA positively mediated the relationship between BAS and PA. Second, PA, in turn, positively mediated the relationship between DSA and life satisfaction. The results can provide useful insights to understand the relationship between older driver's driving property, motivation, affectivity and life satisfaction.

The purpose of this study is to identify the causal relationship of the structural model through approach motivation, avoidance motivation, and digital usage recognition in order to prepare a plan for coexistence with dental hygiene targeting 239 students from the dental hygiene department at a university in Gangwon-do. For statistical methods, SPSS Statistics 24.0 program and AMOS 21.0 were used. As a result of the structural equation model analysis, the motivation for approach was found to be significantly related to digital usage recognition and class satisfaction. In addition, digital usage perception was found to be significantly related to class satisfaction, and class satisfaction was shown to be significantly related to department satisfaction and department recommendation. Lastly, department satisfaction was significantly found in department recommendation. In other words, the coexistence plan with dental hygiene (department) is to expand the convergence of digital classes. In order to solve the problem, it is necessary for schools to establish facilities to expand teaching materials for practical classes and to devise teaching methods.

This study examines the motivation for using YouTube 'mukbang' content by integrating the use and satisfaction approach and the technology acceptance model, and identified the determinants that affect the continuous use intention. A survey was conducted on 358 YouTube 'mukbang' content users, and major results were derived through exploratory/confirmatory factor analysis and path analysis using the SPSS 21.0 program and the AMOS 21.0 program. The main results are presented as follows. First, information seeking motive, stress relief motive, and time spending motive had a positive effect on perceived usefulness, and information seeking motive and time spending motive had a positive effect on perceived ease of use. Second, information seeking motivation, stress relief motivation, and time spending motivate had a positive effect on perceived enjoyment and perceived novelty. Third, perceived enjoyment did not have a significant effect on perceived usefulness. Fourth, both perceived enjoyment and perceived novelty had a positive effect on continuous use intention. Fifth, perceived ease of use had a positive effect on perceived usefulness, and perceived ease of use and perceived usefulness had a positive effect on continuous use intention. This study will have academic significance in that it elaborates a model that can identify the continuous use of YouTube 'mukbang' content by integrating the uses and gratifications approach, and technology acceptance model. Future follow-up studies should contribute to the refinement of models related to the determinants of the intention to continue using YouTube's 'mukbang' content through an attempt to integrate various models.

Though shared virtual memory (SVM) system promise low cost solutions for high performance computing they suffer from long memory latencies. These latencies are usually caused by repetitive invalidations on shared data. Since shared data are accessed through synchronization and the patterns by which threads synchronizes are repetitive, a prefetching scheme bases on such repetitiveness would reduce memory latencies. Based on this observation, we propose a prefetching technique which predicts future access behavior by analyzing access history per synchronization variable. Our technique was evaluated on an 8-node SVM system using the SPLASH-2 benchmark. The results show the our technique could achieve 34%~45% reduction in memory access latencies.

공유 메모리 병렬 프로그램의 주요 문제의 하나는 공유 변수에 접근하는 비 결정적 수행이다. 본 연구에서는 공유 메모리 병렬 프로그램의 접근이상(access anomaly)을 탐지하는 방법들중 수행중 탐지 기법을 보인다. 수행중 접근이상 탐지기법은 접근이상이 존재하면 적어도 하나는 탐지 할 수 있는 장점을 가지고 있다. 수행중 탐지 기법인 English-Hebrew Labeling 은 동기화 명령을 가지고 내포 병렬 루프 프로그램에서 적용될 수 있는 레이블링 기법으로 레이블링에 많은 저장장소를 필요로 하는 단점을 가지고 있었다. 본 연구에서는 새로운 레이블링 방법을 소개하고, 기존의 English-Hebrew Labeling과 최악의 경우에 기억 장소 복잡도의 측면과 시잔 복잡도의 측면에서 효율성을 비교, 분석하게 된다.

The construction industry is now facing a new challenge of green construction. Based on a research question of "what motivates contractors to pursue green construction", the objective of this study is to identify and discuss key characteristics and implications of green construction motivators among major contractors. The Political Economy Approach was adpoted as a main research methodology. The study demonstrated that major contractors show a high level of expectation in the future of green construction and consider economic factors as higher motivators while paying attention to social trends towards green construction. In particular, internal economic motivators were highly considered and the commitment of senior management was viewed as a key motivator.

We design a filtering management scheme with synchronization function under a realtime RFID middleware system for larger-scale data processing. The application interface(AI) is to support a various access protocol, HTTP, XML, JMS, and SOAP for the RFID applications. Generally, the synchronization problem is occurred in multiple accessing of clients for single filtering file. In this paper, we implement a filtering management scheme supporting the synchronization using the filter management process, and then demonstrate the RFID middleware filtering scheme.
