The purpose of this study is to understand the reduction of energy consumption and demand level for education relating to the reduction of energy consumption by middle school students. First, the perception of the reduction of energy consumption had a significant relationship with sex and grade. Second, the demand level for education relating to the reduction of energy consumption showed a significant relationship with only sex. Third, regression analysis on the influence of perception of the reduction of energy consumption showed a correlation between theperception of a reduction of energy consumption and the demand level for education relating to a reduction of energy consumption. The research suggests that students want an education that reduces energy consumption at school implemented during experience-centered and activity-centered discretionary activities, rather than duringtheory-centered curricular activities. It also suggests that overcoming limitations of space, that is, implementation of such education at various places besides school, and the application of teaching and teaming methods which use the internet and image media are more effective for education for the reduction of energy consumption.

With the introduction of the ubiquitous technology, the housing culture centers have demonstrated future housing image or technology. But Ubiquitous Home Services in the future housing were more focused on implementation of environment for the future than exhibition that consumers can experience. The purpose of this study was to identify ubiquitous home services which were realized in domestic future housing and to compare those with results of previous researches on demand for u-services. For this study, field study was conducted with 3 domestic future housings and 14 previous studies on demand of u-services were analyzed by the standard of residents demand. The results of the study showed that u-services for housework and leisure life more than those for security and health, were applied in the future housing. However, residents prefered u-services for security and control of indoor environment to those for housework and leisure life. As a result, it was found thatu-services which residents needed mainly were discordant with those that were displayed frequently in future housing. Also developing u-services reflected the needs of residents, a test bed has to be established in the future housing and then pre-evaluaiton can be conducted.

This study was conducted for the purpose of developing a basic-level TRIZ curriculum to improve students' creativity and problemsolving abilities. Towards this end, literature review, field application study, and a survey on the demand for such curriculum were conducted, as the research methodologies. Specifically, literature review was performed on the TRIZ-related research trends and education trends, and the researchers, who had experience running a TRIZ education program for a few years, ran a basic-level TRIZ for 40 hours as part of the extra-curriculum of A University. An actual survey was also conducted to determine the demand for the development of a basic-level TRIZ curriculum. Of the total of 40 students who were subjected to the curriculum, 31 responded sincerely 1 to the survey. Based on the survey analysis results on the students' recognition of the TRIZ curriculum and of the TRIZ task performance, and on the contents and educational effects of TRIZ, basic guidelines for the development of a basic-level TRIZ curriculum were formulated. Reflecting the results of the survey on the demand for a basic-level TRIZ curriculum, such a curriculum was proposed based on 16-week-long, 3-credit lectures considering the curricula of other subjects in the university.

The purpose of this study is to present the number of necessary facilities for the establishment of safety education facility for students through the analysis of situation and demand of safety experience education facilities so as to effectively implement safety education based on 7 standards of school safety education. 7 standards of school safety education and experience programs of the existing safety experience center were analyzed and the experience program was extracted based on the analysis. Based on the derived program, the experience space was set up, and the existing safety experience facility was analyzed accordingly. Based on this, the number of necessary facilities was suggested by using the calculation formula derived to estimate the scale of the facility expansion. This is the result of estimating the required number of facilities based on the 2015 school age population. In the long run, it is necessary to calculate the appropriate ratio by actually comparing the unit construction costs of the facilities and the vehicles. In consideration of this, it is necessary to plan for the long-term necessary facilities and vehicles for the construction plans.

Retail shops often experience purchase dependence in which some items are purchased together by customers due to their unknown interior associations. This paper develops an inventory model considering partial backordering under purchase dependence and compares the performance of the inventory model that ignores purchase dependence. Computational analyses show that purchase dependence should be incorporated as an important factor of inventory replenishment policy because the impact of purchase dependence can be more significant as the lost portion of the unmet demand orders increases and the item set is more correlated in terms of order demand.

Purpose: This study aimed to investigate recognition, attitudes, knowledge, education experience, and education demand regarding physical restraint among laypersons. Methods: A self-reported questionnaire was completed by 105 randomly recruited laypersons in D city. Excluding 2 incomplete answers, 103 data were analyzed by frequency analysis, t-test, ANOVA, and chi-square test using SPSS 23.0. Results: Laypersons' recognition of physical restraints was rated at 3.37 out of 5 points, and showed a positive perspective. Knowledge on physical restraints was rated at 13.68 out of 18 points and was affected by age and education level (F = 2.845, p = .028)(F = 3.126, p = .029) A majority of the participants had no education on physical restraints. Nevertheless, participants showed intention to receive education in physical restraint to reach further understanding. Conclusion: Education on physical restraints is necessary for lay persons. However, there were education limits for people living in modern times. As an intervention addressing this problem, observing videos on the internet is recommended. Moreover, for advertising/educational purposes, accessing the internet and using smart-phone applications are suggested.

Hypertext Transfer Protocol (HTTP) adaptive streaming has become a new trend in video delivery. An HTTP adaptive streaming client needs to effectively estimate resource availability and demand. However, due to the bitrate of the video encoded in variable bitrate (VBR) mode, a bitrate mismatch problem occurs. With the rising demand for mobile devices, the likelihood of cases where two or more HTTP adaptive streaming clients share the same network bottleneck and competing for available bandwidth will increase. These mismatch and competition issues lead to network congestion, which adversely affects the Quality of Experience (QoE). To solve these problem, we propose a video rate adaptation scheme for the HTTP video streaming to guarantee and optimize the QoE. The proposed scheme estimates the available bandwidth according to the bitrate of each segment and also schedules the segment request time to expedite the response to the bandwidth variation. We used a multi-client simulation to prove that our scheme can effectively cope with drastic changes in the connection throughput and video bitrate.

The demand for metaverse is increasing rapidly due to the development of 3D information technology and the pandemic situation caused by COVID-19. Small and medium-sized enterprises(SMEs) are also in increasing demand for metaverse in the community, meetings, and customer services of their employees. Based on the UTAUT model, this study investigated the acceptance of the Metaverse-type information system(IS) by employees of SMEs. Using the responses from 170 SMEs employees, we conducted the regression analyses SMEs employees' usage intention on Metaverse-type IS. The results of the research analyses were as follows. First, among the variables of the UTAUT model, performance expectations, social influence, and promotion conditions had a significant effect on the intention to use. Second, among the variables derived from the industrial specificity of Metaverse-type IS, only individual innovation had a significant influence on the intention to use. Last but not least, in the relationship between the intention to use Metaverse-type IS and the influencing factors, only individual innovation was significant in the moderating effect according to past metaverse use experience.
