There are a lot of differences in the Eastern and Western space culture. Especially, Comparing to Japanese, Koreans are not good at utilizing the small space and react effectively. Therefore, the interior space of public transportation needs to be relatively developed to highly reasonable level in Korea. The purpose of this paper is to propose the concept of Korean tradition in urban transit interior layout, which means vernacular design. The interior layout should be made in terms of the emotional aspect not functional one. In order to study the notion of national character, this study refers the concept of interior layout of the public transportation to the layout of traditional architecture and modern office. The research of vernacular design can provide national character and traditional design and can make a success in a practical use and a visual effect.

Backfire occurrence must be controlled for the practical use of hydrogen fueled engine. It was found from preceeding studies that crevice volume around piston rings could effect a backfire occurrence. In this study, a possible countermeasure to backfire occurrence was evaluated by using multi point ignition method around piston ring. The results showed that backfire limited equivalence ratio was increased by a little due to a enhancing effect of mixture combustion around piston crevice volume.

This study's objective is to use the construal-level theory (CLT) to explore the effect of the utility of online travel reviews on tourists' perception. To accomplish this goal, online travel reviews are divided into two different categories based on concreteness, and the usefulness of each review is compared with the temporal dimension of psychological distance. The results show that close future tourists are more influenced by concrete reviews than abstract reviews; however, the far future tourists are more influenced by abstract reviews than concrete reviews. Based on these results, theoretical and practical implications are discussed, and suggestions are made for future research.

Purpose: Due to COVID-19, the rapidly changing untact culture from offline to online has spread rapidly, increasing the utilization of omni-channel. However, among the studies on consumers in the online market, there are not many studies that analyze Shopping Values and attitudes toward omnichannel Acceptance. Research design, data, and methodology: This study investigated through empirical analysis how Shopping Values and innovation propensity of consumers using omni channels affect omni channel Acceptance attitudes. The analysis results based on a total of 268 questionnaires using SPSS v.23 and AMOS v.23 statistical programs are as follows. Results: First, it was found that the perceived Value of omnichannel use had a positive effect on the innovation tendency, and the pleasure Value had a greater effect than the actual Value. Second, it was found that the practical and hedonic Value of the omnichannel had a positive effect on the attitude of service Acceptance. Third, it was found that Omni Channel's consumer innovation tendency had a positive effect on service Acceptance attitude. Conclusion: This study proved that Shopping Value perception and individual innovation propensity for omnichannel services have a positive effect on Acceptance attitude, and it is of academic significance in that it expanded understanding of what factors are needed to increase Acceptance attitude of Omni Channel services.

In this study, a novel magnetic field generator, using a shielding effect for controlling the dynamic stiffness and damping of magnetorheological gels, is proposed. A magnetorheological gel is a smart material that can alter its stiffness and damping, and it can be used as a vibration absorber and in vehicle suspension. It is necessary to control the magnetic field to use magnetorheological gels in various applications. There are two types of magnet field generators, namely the electromagnet and permanent magnet, and the electromagnet is generally used in practical applications. However, owing to its limitations, the electromagnet is not suitable for long-term use. Therefore, in this paper, a novel magnetic field generator is proposed to address such problems for use in real applications.

The elderly is a target group for health functional foods (HFFs). We surveyed 825 Korean elderly (71.4- years-of-age) for HFF use and significant variables for HFF use including demographic characteristics, health related variables, and nutritional beliefs. The prevalence of HFF use was 48.7%, and among all types of HFF, red ginseng products were eaten most frequently, followed by ginseng products, nutritional supplements, and mushroom products. The mean age of users of HFFs was lower than nonusers (p<.01). HFFs were eaten more frequently by subjects from families living with a spouse or unmarried children (p<.01) and those with higher levels of monthly pocket money (p<.001). HFFs were also eaten more frequently by subjects or their spouses with a higher education level (p<.001). The social activity participation ratio (p<.01) of subjects and the HFF usage ratio by the spouse (p<.001) were higher in users of HFF than in nonusers. Dietary assessment scores were not different between the two groups, and users had a more positive view concerning the potential health benefits of HFFs than did nonusers (p<.001). Most users of HFF ate HFFs "when they were healthy" (52.2%) and experienced some effect through HFF use (45.8%). Most users of HFFs received information on HFFs through their families or relatives (38.1%) and most purchased HFFs at the pharmacy or oriental medicine clinic (44.8%). HFF users preferred multivitamin- and Ca-supplements most among the vitamin and mineral supplements belonged to HFFs. The above results show that HFF use is widely spread among subjects, and that use of HFF is influenced by various factors. Thus, practical guidelines for HFF use should be provided for the elderly through elderly focused-nutrition education based upon significant variables and consumption behaviors for their HFF use of present study.
