  • This study deals with the BIM (Building Information Modeling)-based energy performance analysis implemented in EnergyPlus. The BIM model constructed at Revit is updated at Design Builder, adding HVAC models and converted compatibly with the EnergyPlus. We can obtain the input values about HVAC system and building environment such as HVAC system efficient, the number of air changes and energy consumption of equipment on applying GAs (Genetic algorithms). After modification about HVAC system, Optimization about HVAC system energy consumption can be analyzed. In order to maximize the building energy performance, a genetic algorithm (GA)-based optimization technique is applied to the modified HVAC models. Throughout the proposed building energy simulation, finally, the best optimized HVAC control schedule for the target building can be obtained in the form of "supply air temperature schedule". Throughout the supply air temperature schedule is applied to energy performance simulation, we obtained energy saving effect result on simulation.

  • For the introduction of the electricity of the special design and supervision system to Protect the faulty-workmanship of the electricity equipment and to reserve the electricity safety, last 1995 "Electricity Technology Management Act" were carried out enactment. March 2002, we introduced the pre-Qualification system that is selected the competent company about the electricity design and supervision service over so much capacity which is ordered by the Public institution such as the nation, local autonomous entity, government investment institute and so on. December 2005, the electricity equipment over so much capacity was taken the housing construction plan's approval by the housing act in case, the municipal or district governor with the authority to approve who selected the electricity supervision company according to the pre-Qualification system. Due to the introduction of the system, we could expect the rights and interests increase of the consumer by eradicating dumping of the close relationship between supervision company and the builder, reduction and concurrent position of the supervisor, according to confirm the quality of the electricity equipment and electricity safety. In spite of introducing of the system, the problems occured as reducing the electricity designer's task range compared with different field, modifing the supervisor's rank system rationally, because of researching about the electricity design and supervision technique lacks. Also, KEEA(Korea Electric Engineers Association) manage the caller of the electricity design and supervisor(company or people), but the problems occured as opening to the public about the curler management, introducing automatic bidding system and We need the solution plan about this. Consequently, we consider the present situation of the domestic and outside and problem about the electricity design and supervision system in this paper, try to present rational operation plan through this.

  • This paper suggests that the meaning and the direction of character education should be understood and approached from a point of view which human formation is regarded as the essence of education. The best way of approach to the character education with this point of view could start from the teachers' character, because teachers are key actors for character formation of students. This study therefore places strong emphasis on the importance of teachers' character and suggesting liberal education, as a key solution, its aim is raising and developing the whole human being. The purpose of this study is to explore the possibility of liberal teacher education. With this purpose of study, the author argues the moral dimension of teaching and the importance of the teachers' role as a character builder in ch.II. In ch.III, the present state of teachers' character education is examined and is argued the necessity of liberal perspective for teacher education to stress the character formation of teachers. The liberal teacher education means that the teacher education is integrated into the quality of liberal education which emphasizes the whole human formation, transformation of personality and critical reflection for human formation. The ch. IV contains exploration of the possibility of liberal teacher education by discussing the compatibility between liberal education and vocational education. Furthermore, it covers how teacher education can reflect the quality of liberal education on the aim of teaching, contents and methods of teacher education concretely.

  • 1. Introduction: Contrast to the offline purchasing environment, online store cannot offer the sense of touch or direct visual information of its product to the consumers. So the builder of the online shopping mall should provide more concrete and detailed product information(Kim 2008), and Alba (1997) also predicted that the quality of the offered information is determined by the post-purchase consumer satisfaction. In practice, many fashion and apparel online shopping malls offer the picture information with the product on the real person model to enhance the usefulness of product information. On the other virtual product experience has been suggested to the ways of overcoming the online consumers' limited perceptual capability (Jiang & Benbasat 2005). However, the adoption and the facilitation of the virtual reality tools requires high investment and technical specialty compared to the text/picture product information offerings (Shaffer 2006). This could make the entry barrier to the online shopping to the small retailers and sometimes it could be demanding high level of consumers' perceptual efforts. So the expensive technological solution could affects negatively to the consumer decision making processes. Nevertheless, most of the previous research on the online product information provision suggests the VR be the more effective tools. 2. Research Model and Hypothesis: Presented in

    , research model suggests VR effect could be moderated by the product types by the usage situations. Product types could be defined as the portable product and installed product, and the information offering type as still picture of the product, picture of the product with the real-person model and VR. 3. Methods and Results: 3.1. Experimental design and measured variables We designed the 2(product types) X 3(product information types) experimental setting and measured dependent variables such as information usefulness, attitude toward the shopping mall, overall product quality, purchase intention and the revisiting intention. In the case of information usefulness and attitude toward the shopping mall were measured by multi-item scale. As a result of reliability test, Cronbach's Alpha value of each variable shows more than 0.6. Thus, we ensured that the internal consistency of items. 3.2. Manipulation check The main concern of this study is to verify the moderate effect by the product type of usage situation. indicates that our experimental manipulation of the moderate effect of the product type was successful. 3.3. Results As
    indicates, there was a significant main effect on the only one dependent variable(attitude toward the shopping mall) by the information types. As predicted, VR has highest mean value compared to other information types. Thus, H1 was partially supported. However, main effect by the product types was not found. To evaluate H2 and H3, a two-way ANOVA was conducted. As
    indicates, there exist the interaction effects on the three dependent variables(information usefulness, overall product quality and purchase intention) by the information types and the product types. As predicted, picture of the product with the real-person model has highest mean among the information types in the case of portable product. On the other hand, VR has highest mean among the information types in the case of installed product. Thus, H2 and H3 was supported. 4. Implications: The present study found the moderate effect by the product type of usage situation. Based on the findings the following managerial implications are asserted. First, it was found that information types are affect only the attitude toward the shopping mall. The meaning of this finding is that VR effects are not enough to understand the product itself. Therefore, we must consider when and how to use this VR tools. Second, it was found that there exist the interaction effects on the information usefulness, overall product quality and purchase intention. This finding suggests that consideration of usage situation helps consumer's understanding of product and promotes their purchase intention. In conclusion, not only product attributes but also product usage situations must be fully considered by the online retailers when they want to meet the needs of consumers.
