  • The purpose of this study is to develop learning modules for environmental education using goal-based scenarios and to examine their pedagogical benefits at the elementary educational level. To enhance environmental knowledge, skills, attitudes, and behavior, this research developed learning modules relevant to three sub-dimensions of environmental education: education about environment, education in environment, and education for environment. In particular, this study provided useful educational strategies based on students' everyday lives. The developed modules consisted of three parts: 1) acquiring knowledge concerning the cause of global warming, 2) practicing and internalizing environmental knowledge in students' everyday lives, and 3) extending and disseminating environmental knowledge and awareness to other people. After applying the modules, the students acquired knowledge regarding the causes of global warming through discussions with their peers, and furthermore, exercised pro-environmental behaviors in their everyday lives. Moreover, the participants created UCC to urge other people to act for environment.

  • Purpose : This study was conducted to survey the preliminary data on risk behaviors and to identify the factors that prevent risk-behaviors in late adolescence. Methods : Freshmen(n=1,297) beginning the first semester in Korea University, Seoul, Korea completed self-administered risk behavior questionnaires, comprising 5 domains : demographics, smoking, drinking, drug abuse and sexual behavior. Results : The rate of smoking experience was higher in people having friends who smoke and the predictors of transition to current smoking were male gender, urban residence, friends' smoking, and nicotine dependence. The rate of high risk drinking was higher among students who are male and who had experience of heavy episodic drinking. The study group showed a low prevalence of narcotic users, but two-thirds of students could get medicine easily without prescriptions. The prevalence of sexual experience was 6.5 percent, and the sexual education was not a predictor of contraceptive behavior. The prevalence of homosexuality was 1.6 percent, and the rate of mostly heterosexuality was higher in female students. Conclusion : The main targets of youth health education should be campaigns aimed at atcessation of reinforcing risk behaviors and the development of a surveillance system for the prevention of chronic disease. These results can be used to find risk factors of health-risk behaviors among late adolescents.

  • In this paper, a system that implementation of Access Control System Using Biometric System. Biometries is science which deals with verifying or recognizing using physiological or behavioral characteristic Access Control System uses Bionietric system to make an access control system. Biometrics goes under the study of bio-recognition or bio-measurement. It is a technology or study that identifies individuals using one's Biometric character. Access control system is a system used to identify one's entrance and exit, personal management, and security. Access control system can be joined with Biometric system to produce easier use and more sufficient effects. Access control system using Weigand (Data format) signal output, can replace earlier RF Card systems and make an access control (security) system. It uses RS-232, Rs-422 or TCP/IP type communication with the computer so an embedded system can be controlled using the software.

  • Many studies in the field of information security reveal the need to increase awareness. However, although awareness of information security has been raised to a considerable extent, actual security behavior has been shown to fall short of that. Therefore, we wanted to identify the role of psychological factors in making information security decisions by conducting a experimental study. The results show that there are differences in perception of information security risks according to the probabilistic distance and the degree of relative optimism due to social distance. In relation to their relative optimism and intention of information security, they reduced the level of perceived risk compared to those close to them and found that their influence varied according to their probabilistic distance. This study has made valuable attempt in terms of methodology and it is meaningful that the psychological factor is taken into consideration for the information protection behavior, so that the range of relative optimism that actually affects the perception of risk is narrowed. It is expected to contribute to the improvement of information security level of information technology users and protection of information assets by empirically identifying necessity of various approaches to decision making process for information security.

  • People believe that they make a rational decision. But the results of behavioral economics research show that people make a emotional decision at many times. The perception of fairness is one of the example in emotional decision. Sometimes people give up their monetary profit and revenge counterpart when they feel unfair. So the perception of fairness is very important. Two experiment was conducted. In experiment 1, researcher studied the effect of the pre-investment cost in perception of fairness. The result showed people who had pre-investment cost thought more unfair but were more likely to continue prior decision. In experiment 2, researcher studied the effect of type of CEO and message frame in perception of fairness. The results showed that people thought the proposal was more unfair when CEO was son of founder and message was gain and loss framing message.

  • In this paper, we propose the matching model between virtual reality and the real-world for peoples with limited mobility. The proposed matching model is consist of four parts: wearable input device-based PC control, hand-motion pattern recognition, application software, and matching between virtual reality and the real-world. To recognition mouse functions and hand-motion patterns from six-axis coordinate of wearable input device, RF communication is used. In addition, to easily control the real-world, virtual reality has been implemented with realism of the real-world. Some experiments are conducted so as to verify the proposed model, and as a result, hand-motion recognition as well as virtual reality control are well performed.

  • This study approached the concept of practical or praxis in Family and Consumer Science based on the review of the concept of phronesis in Aristotle's Nicomachean Ethics. Aristotle divided human soul into rational part and irrational part. A virtue related with rational part is intellectual virtue and a virtue related with irrational part is moral virtue. Rational part is divided into calculative part and scientific part. Phronesis is one of an intellectual virtue in calculative part of soul. Aristotle defines phronesis as a state of soul that issues in praxis. Phronesis in narrow sense is a virtue which leads to praxis and it is differ from either sophia or techne. Phronesis in broad sense it includes both praxis and poiesis. Phronesis is closely related with moral virtue. Because moral virtues are habits according to right reason, hence right reasons should be considered, and this is intellectual virtue. It is called for attention that what the concept of practical or praxis in Family and Consumer Science Education should be for the determination of the relation with Practical Arts and Technology. This study proposed a tentative conceptualization of praxis and phronimos in context of Family and Consumer Science Education.clothing planning and the most categories(83.3%) had connections of repetitions. In the clothing material section, categories evaluated as gaps and developments were 55.6% and 44.4%. The clothing construction.
