Recently, the beauty service industry in Korea is growing rapidly as women have increased role in society and consumers have more diversified desire for beauty. In that sense, studies on the environment of transaction is necessary to maintain the customers who use beauty service which Is one of the most prominent services in Korea. However, there is a lack of systematic investigation on that. Under those circumstances, this study tries to propose strategies by shedding light on the reasons of store loyalty based on empirical study. Furthermore, securing regular customers is deemed to be the most important thing as the competition among stores are getting fiercer in the wake of increase in the number of beauty salons. In that light, this study tries to shed light on the transaction cost clearly which affects the store loyalty, and focuses on the development of integrated research model for the transaction cost related to the environmental characteristics of beauty service industry and for the store loyalty.

We use heat pumps with thermal storage system to reduce peak usage of electric power during winters and summers. A heat pump stores thermal energy in a thermal storage tank during the night, to meet load requirements during the day. This system stabilizes the supply and demand of electric power; moreover by utilizing the inexpensive midnight electric power, thus making it cost effective. In this study, we propose a system wherein the thermal storage tank and heat pump are modeled using the TRNSYS, whereas the control simulations are performed by (i) conventional control methods (i.e., thermal storage priority method and heat pump priority method); (ii) region control method, which operates at the optimal part load ratio of the heat pump; (iii) load response control method, which minimizes operating cost responding to load; and (iv) dynamic programming method, which runs the system by following the minimum cost path. We observed that the electricity cost using the region control method, load response control approach, and dynamic programing method was lower compared to using conventional control techniques. According to the annual simulation results, the electricity cost utilizing the load response control method is 43% and 4.4% lower than those obtained by the conventional techniques. We can note that the result related to the power cost was similar to that obtained by the dynamic programming method based on the load prediction. We can, therefore, conclude that the load response control method turned out to be more advantageous when compared to the conventional techniques regarding power consumption and electricity costs.

The purpose of this study was to survey the distribution patterns of volatile organic compounds(VOCs) and formaldehyde in the various indoor environments using cluster analysis. We investigated VOCs and formaldehyde in subway stations, underground shopping areas, medical centers, maternity recuperation centers, public childcare centers, large stores, funeral houses, and indoor parking lots from June,2005 to May,2006. Concentration of TVOCs in maternity recuperations was 2,605.7 ${\mu}g/m^3$ that was higher than the guideline and other facilities. TVOCs in public childcare centers was 1,951.6 ${\mu}g/m^3$ also it exceeded the guideline. Moreover, concentration of TVOCs in every facility exceeded the guideline of Department of Environment, Korea. In case of formaldehyde, mean concentration, 336.5 ${\mu}g/m^3$, in only public childcare centers exceeded the 120 ${\mu}g/m^3$ of the guideline. Finally, by applying cluster analysis, three pattterns of the indoor air pollutions were distinguished. In the results of analysis, concentrations of TVOCs and formaldehyde of cluster 3 were higher than cluster 1 and 2 that were 2,561.4 ${\mu}g/m^3$ and 184.9 ${\mu}g/m^3$, respectively.

Apartment complex, buildings, markets and department stores have inner parking lots which can accept many cars but drivers waste lots of times to find the empty parking spaces in crowding parking lots. In this paper, we proposed the inner parking information support system based on microprocessor which can decrease roaming times to find vacant parking spot in confusing parking lots through notice monitor and provide SMS to make it easy to find parked place. Proposed system consist with RFID system for detecting access of cars, microprocessor system for processing data of checking existence of cars on parking spots and communicating with server, and server system which processes information of cars' in and out, guides empty parking spots and parked location to drivers. Suggested system is realized by handmade model parking lot size of 8 cars, and we confirmed practicality by providing information using parking notice monitor and single message service.
The purpose of this study is to suggest an anti-aging health care plan through a literature analysis of the life activity system of Oriental Medicine. The source of normal maintenace, development, and change of the natural world and the human body's life activity process is the dynamical cooperative equilibrium of the internal Shen-Ji's discipline that creates, grows, changes, makes differences and stores(生长化收藏) and external Qi-Li's process of change from birth to growth, maturity to old age and ending of life(生長壯老已). Therefore, it was analyzed that the natural and human life activity processes are normally maintained, developed, and transformed. As a result, when the natural healing power of Genuine-Qi, the source of the human vitality, rises with the 'breathing massage' that combines a static breathing method which is anti-aging health care method applying the lifting entering movement of Qi and a dynamic abdominal massage, and it harmonizes the Shen-Ji which is the life process system and Qi-Li so that it is believed to be helpful in prolonging a healthy lifespan.
Purpose - As the competition in the foodservice franchise industry and the market becomes fierce and the entry barrier is lowered, the foodservice franchisor and franchisees strive to increase their competitive advantage in the market. Therefore, the franchisor and franchisees use experience management strategies to enhance the positive experiences of customers visiting the stores. In this regard, this study examines the effects of customer-oriented activities (physical-, social-, health-, and service-oriented activities) on utilitarian and hedonic values, and loyalty using stimulus-organism-response (S-O-R) model and value-expectancy theory. Research design, data, methodology - The data were collected from panels of online survey company, who visited a foodservice franchisee within last month. The survey was conducted for about 15 days from March 7, 2019 to March 21, 2019, and about 3,500 e-mails and messages were distributed to ask for the survey. A total 412 responded and completed the questionnaires. Of the 412 completed questionaires, 12 were discarded due to missing and misinformation data and 400 were retained for further data analysis. Results --The results showed that social oriented activities, health oriented activities, and service oriented activities had positive effects on hedonic value, while physical oriented activities did not have a significant effect on hedonic value. Health oriented activities and service oriented activities had positive effects on utilitarian value, while physical oriented activities and social oriented activities had no significant effects on utilitarian value. Hedonic and utilitarian values also have a positive effect on loyalty. Conclusions - First, food service franchises should provide services and menus in consideration of the health of customers. When a customer visits the store, franchisee should provide more health-oriented food or materials and clean and comfortable conditions so as not to threaten the health of the customer. Second, the food service franchise must build a service-oriented system. Foodservice franchisor need to provide continuous service training not only to the franchisees, but also to the employees of the franchisees. Third, franchise should design a store where customers can form social exchanges through providing various information exchange to customers and making the store as a local community center.
Purpose: Brand hearsay refers to information that can be acquired from advertisement, media publicity, and word-of-mouth prior to experiencing products or services of brands. Previous information about brands obtained through brand hearsay affects consumer behavior in choosing brands. Moreover, brand hearsay is an effective communication method in promoting brands to consumers. Thus, bakery franchises need to improve strengths and differentiate characteristics of their brand, thereby attracting more consumers. Therefore, this study investigates relationships the effect of brand hearsay on consumers' brand attitude and brand loyalty in the context of franchised bakery brands. Research design, data, and methodology: A research model was proposed to examine structural relationships between brand hearsay (advertising, publicity, word-of-mouth), brand attitude, and brand loyalty. An online survey was conducted to consumers who had an experience of visiting a franchise bakery. A total of 513 responses were used for data analysis. SPSS 22.0 was used for analyzing general demographics, and SmartPLS 4.0 was used to test validity and reliability of the proposed model. Result: Among attributes of brand hearsay, advertisement and word-of-mouth had positively significant effects on brand attitude, but no significant effect was found between publicity and attitude. Advertisement had a positively significant impact on brand loyalty, while publicity had a negative effect on brand loyalty opposite to hypothesis. Moreover, brand attitude had a statistically significant effect on brand loyalty. Conclusions: In the context of franchise bakeries, brand hearsay contents may change consumers' attitude toward brands but does not increase brand loyalty. Though media publicity does not affect consumers' attitude toward brands, it may decrease brand loyalty when consumers are too exposed to it. In addition, it is necessary to enhance brand attitude to increase brand loyalty of customers. This study provides bakery franchisors and franchisees information about which type of brand hearsay (e.g., advertisement, word-of-mouth, media, publicity) is effective in enhancing brand attitudes and loyalty of consumers. Further studies may include other variables (e.g., trust) in addition to attitude and loyalty, or compare findings based on brand characteristics (e.g., low-to-medium/high prices, store size).

Background and Purpose: Episodic memory is a system that receives and stores information about temporally dated episodes and their interrelations. Our study aimed to investigate the relevance of episodic memory to time perception, with a specific focus on simultaneity/order judgment. Methods: Experiment 1 employed the simultaneity judgment task to discern differences in time perception between patients with mild cognitive impairment or dementia, and age-matched normals. A mathematical analysis capable of estimating subjects' time processing was utilized to identify the sensory and decisional components of temporal order and simultaneity judgment. Experiment 2 examined how differences in temporal perception relate to performance in temporal order memory, in which time delays play a critical role. Results: The temporal decision windows for both temporal order and simultaneity judgments exhibited marginal differences between patients with episodic memory impairment, and their healthy counterparts (p = 0.15, t(22) = 1.34). These temporal decision windows may be linked to the temporal separation of events in episodic memory (Pearson's ρ = -0.53, p = 0.05). Conclusions: Based on our findings, the frequency of visual events accumulated and encoded in the working memory system in the patients' and normal group appears to be approximately (5.7 and 11.2) Hz, respectively. According to the internal clock model, a lower frequency of event pulses tends to result in underestimation of event duration, which phenomenon might be linked to the observed time distortions in patients with dementia.

With the advent of Metaverse, a promising new era for business on virtual reality (VR) platforms has dawned. In this rapidly expanding Metaverse platform, the potential for virtual fashion marketing through avatars is vast, with leading fashion brands already making strides by creating virtual fashion stores or hosting virtual fashion shows. However, the research on fashion-related industries in this newly emerging virtual world platform is still in its infancy. This study sought to identify the relationship between the characteristics of the Metaverse and the factors that influence how the perceived value of virtual fashion products affects purchase intention. A survey was conducted with three hundred Korean respondents, and the hypothesis was verified through analysis using the SPSS statistical program. Our analysis revealed that the sense of presence significantly influences the value of fashion products on the Metaverse platform. As a result, the sense of presence significantly influenced the emotional, visual authority, and economic value of the avatar virtual fashion perceived by users. Second, enjoyment, visual authority, and economic value influence users' intention to purchase virtual fashion items. In addition, all of these perceived value factors were confirmed to have a significant partial mediating effect on the impact of the presence of the Metaverse platform on the purchase intention. Through this study, we empirically analyzed the causal relationship between the characteristics of the Metaverse platform and the virtual fashion experience using avatars - a topic that has yet to be covered. We formed new insights into virtual fashion consumption, providing primary data for related research streams. Our survey respondents consisted only of those with recent Metaverse experience, so the research results were highly effective.
A Nationwide health care utilization survey was conducted from March 11 to September 19, 1985 to assess the level of illness and the magnitude of medical care utilization. A probability sample of 15,427 persons was taken from 180 Enumerated Districts designated by the Economic Planning Board. Of those 4,500 housewives were proxy respondents. A interview was conducted with pre-tested questionnaire schedule which was recorded by well trained interviewers. Age and sex compositions of the study population were similar to those of general population structure in 1985. The major findings of this survey are as follows : 1) A total of 64.5% of the study population lived in city area and 35.5% lived in county area. 2) While no difference was observed in interview rate between city and county area, it showed statistically significant difference in the medical security program coverage rate between the two areas(44.7% and 37.1%, respectively) 3) Morbidity rate was 79 per 1,000 persons during the two week periods. There was difference in age and sex adjusted morbidity rates between city and county area. Furthermore morbidity rates by the status of the program were significantly difference between the two areas. 4) Average ambulatory care utilization rate was 7.2 visits per person per year and average admission rate was 1.8 per 100 persons per year. There was significant difference in average ambulatory care utilization rate by the program. but no significant difference in medical utilization rate between city and country area. 5) The major symptoms of the perceived illness was the respiratory system(44.1%). 6) A total of 50.4% of the perceived illness among the covered group by the program were treated at the hospital and clinics, but those who are not covered used primarily drug stores(61.3%).
