This paper is the transient analysis for choosing the optimal SCR ratings of AC3 utilization category testing equipment(AC3 TE) used for electrical durability test for magnetic switch according to IEC60947-4 Annex B by utilizing EMTP -ATPDraw. Magnetic contactor closes and opens the motor load with ON/OFF switch of electronic contactor. It is also used for protecting and controlling the load. Magnetic contactor detects the over-current flow in the load with a over-current relay and disconnects the load by opening its control power. The key cost of AC3 TE is the SCR ratings. The more decreases SCR ratings, the more decreased the cost is, but it is impossible to ensure the reliability. On the other hand, the more increases SCR ratings, the more increased the cost is. Thereupon, in this paper after the testing circuit is simulated by using EMTP-ATPDraw the SCR ratings will be applied in order to guarantee the testing reliability of PT&T(Power Testing and Technology institute in LG Industrial Systems Co.,Ltd.).

With the goal of searching for the ways to help market traditional beverages as take-out products, this study conducted a survey over men and women over 20 years of age in Seoul and Gyeonggi Province. Their perceptions of importance in choosing traditional beverages and conventional drinks were examined for difference. As a result, taste, reliability, health, flavor, and price were important at general beverage, while taste, health, flavor, reliability, price, and color were in choosing traditional beverages. The participants mentioned recovery from fatigue as the most favorable added feature of traditional beverages, which was followed by beneficial for adult diseases and facilitating digestion. Their preferences toward using them to satisfying a sense of hunger was relatively low. The participants preferred price range was $3,000{\sim}3,500$ won, their favorite ingredients were functional ones, and their favorite shop design was a traditional style. It seems that the marketability of traditional beverages as take-out products is high. The promotion and development efforts should involve marketing to women, differentiation strategies from other drinks, a graceful image, reliable drinks, and additional functions such as recovery from fatigue and can benefit adult diseases.

Purpose In recent years, mobile payment service users have been rapidly increasing. Previous researchers focused on the mobile usage situation such as the elements of mobile payment service, usage pattern, and user behaviors, and the research that is approached from the viewpoint of the user is still insufficient. The aim of this study is to suggest a acceptance-resistance motivation model of choosing a mobile payment service based on the Herzbergs Two-Factor Theory by investigating users' motivation and hygiene factors. Design/methodology/approach For the purpose, literature reviews on factors of choosing a mobile payment service were conducted and classified motivation and hygiene factors. Two hypotheses were set as follows: Hypothesis I is that motivation factors have a positive impact on the choice of mobile payment service, and Hypothesis II is that hygiene factors have a negative impact on the choice of mobile payment service. To test two hypotheses, this study conducted an online questionnaire survey and a multivariate discriminant analysis. Findings The result found that mobile payment service is more likely to be replaced with mobile by improving convenience, simplicity, and ease of use that affect the acceptance motivation of mobile payment service. This result supported the Hypothesis I but not Hypothesis II and contributed to provide implications for future mobile payment service development and marketing utilization.

This study is to investigate patient's choice of health care and the demand for Korean traditional medicine care in rural areas in 1995. It tried to evaluate the effect of out-of-pocket expenditure, travel time, and waiting time on improving care-seeking and substituting clinical medicine for pharmacy care and Korean traditional medicine care in rural areas. The statistical model of this study is conditional logit to estimate effects of choice-specific and individual-specific characteristics on the choice of type of services. This study used, as explanatory variables, average out-of-pocket payment, travel time, and waiting time of services required to use the services. The model was empirically tested using data from 1995 Korean National Health Survery. The results showed that rural Koreans responded to out-of pocket payment and travel time. Increases of out-of-pocket payment and travel time decreased the probability to choose care in rural Korea. Rural Koreans were more likely to seek care than others with low out-of-pocket payment and travel time. The probability of choosing Korean traditional medicine were higher among the members of the households with higher education level and older persons, while they were lower in the households with large family than others compared with the probabilities of choosing public health facilities. The result of this study implies that policy on use of health care in rural Korea can be focused in managing travel time and out-of-pocket payment.

Recent planning for bicycle use is relatively low compared to other studies. Although studies for the bicycle roads accessibility are actively underway, those considering topographical elements and characteristics of the user behaviors are very limited. Choosing paths of cyclists is typically influenced by slopes and intersections as well as optimal distance. This study presents a method to find optimal paths considering topographical elements in case of choosing paths for school commuting using bicycles. Conversion formulae suggested here are tested on a Songpa area using round-trip directions and compared with traditional optimal path computation.
