가상현실 기반 훈련 시뮬레이터는 현실에서 재현이 어렵거나 불가능한 상황을 가상공간 상에 구현하여 훈련을 수행할 수 있는 시스템이다. 화학공장, 플랜트 등 대형 기계설비 내에서 발생하는 각종 사고에 대한 대응훈련은 훈련시간 및 비용 증가, 훈련자의 안전 확보가 어렵고 반복적인 훈련 및 평가가 어렵기 때문에 가상현실을 이용한 훈련 시뮬레이터를 통하여 수행되는 것이 바람직하다. 본 논문에서는 대형 기계설비 안전대응 훈련 시뮬레이터의 훈련자 평가 시스템을 설계하였다. 훈련의 정량적인 평가를 위하여 훈련 시나리오 내 임무수행 여부, 수행시간/거리에 대한 평가와 함께 특정 훈련동작에 대한 평가를 실시하기 위하여 모션캡쳐 데이터를 활용한 훈련동작 평가 모듈을 설계하였다. 평가 결과의 시각화를 통해 훈련자 피드백 제공 및 반복적인 훈련 수행을 통한 안전대응 능력 향상이 가능하다.

As the web advertising proliferates due to the explosive growth of Internet users, there is a research need for the consumers' general perception on the individual advertisements in the web. This research studies whether the characteristics of Internet advertising(entertainment, informativeness, purchase facilitation, irritation) influence the consumers' attitudes in the Internet environment. This is based on the fact that the web as an advertising channel is quite different from the traditional advertising channels. Twc different surveys are conducted; one is to study consumers' general responses for the Internet advertising in general, and the other is to study more specifically consumers' attitudes for the six different advertising messages(product advertising, corporate image advertising, on-line catalog, billboard, contest/game advertising and online directory of firms). Entertainment and informativeness factors are found to be positively related with the consumers' general attitudes for the web advertising, whereas purchase facilitation and irritation factors have no relationships. Also, a set of advertising strategies for the six different advertising messages are given based on the findings about the relationships between the six advertising messages and the four influencing factors.

Risk has been considered as one of very important topics in traditional consumer behavior theoretically and practically since its tendency of minimizing errors rather than maximizing utilization in addition to its intuitive appealing with very high explaining power. In addition to a traditional view of risk, importance of risk in online transactions such as Internet banking is due to technical instability in security of the Internet as well as temporal and spatial separation of transaction partners. Therefore, risk in online transactions should be analyzed by a very comprehensive way since it is very inherent in the Internet. The objective of this study is to suggest a research model for explaining the use of online transactions in some risk related variables including risk results, security result, perceived security, and social influence and show its validity by applying it to Internet banking users. In result, hypotheses suggested by our research model are shown to be valid ones.

This study examines the effects of self-presentation and aesthetics on purchase intentions toward a brand-new smartphone through a research model that accounts for these intentions in a more comprehensive manner than traditional ICT frameworks. The constructs were selected based on the three-level processing theory: aesthetics at the visceral level, perceived usefulness and playfulness at the behavioural level, and self-presentation at the reflective level. The hypotheses were developed from self-presentation theory and the attractiveness stereotype which is one of theories in human-computer interactions (HCI). For the validation of hypotheses, the research model was empirically tested for the purchase intention of Apple's iPhone5 by university students in Korea.

This paper was development of remote controller of pumping system by using ubiquitous for underground water contamination prevention in the area of glasshouse facility. This paper automatically controls from to temperature and humidity for pumping sprinkler at water hanging cultivation. This prevents indiscreetive development of underground water, and prevents damage of environmental pollution without complementary measures in case of water lacked humble-void. The result of this research, confirms decrease of electrical fee, prevention of indiscreet underground water usage and its drying up thought optimum farm products management and pumping control system.

In this study, a customized model (CM) for the efficient operation of cold chain logistics considering the hypergeometric distribution is proposed. The CM focuses on the segmentation market of ready-to-eat foods and juices made from fresh materials. Companies should determine the amount of production by predicting consumer preferences and quantity to ensure high-efficiency production. The CM is represented as a mathematical formulation and implemented using the genetic algorithm (GA). Addition, the relative weights of CM are calculated. Further, the calculated weights are applied to the GA. In the numerical experiment, hypergeometric distribution is used to calculate the relative weights between the range of production quantities and the customized amount. Experiment results are the values of relative weights and the comparison results by average values of handling cost, total cost and CPU time. Finally, the significance of this study is summarized and a future research direction is remarked in conclusion.
