The serving robot is defined as a robot that carries cooked food to a customer table or collects and carries bowls after eating. This study presented a research model to find out the causal relationship between customer satisfaction and continuous use intention through the three factors of serving robot service quality. In addition, in order to empirically verify the above research model, a survey was conducted on customers using serving robots within the last 5 months. 300 copies were analyzed using SPSS 20 as the final analysis, excluding unfaithful responses. The main findings of this study are as follows. First, serving robot service quality (typical) found to have significant effect on customer satisfaction and continuous use intention. Second, it was found that serving robot service quality (reliability) had a significant effect on customer satisfaction and continuous use intention. Third, it was found that serving robot service quality (ease) did not significantly affect customer satisfaction and continuous use intention.

Digital mans a method of data processing in the form of numbers. Today the entire world is undergoing profound transformations brought about by digitalization, new information and communication technologies, and widespread use of computers. This is a so-called digital age, which is witnessing massive changes brought by globalization such as more powerful civil society, the rise in win's social status and more common phenomena of pursuit of pleasure. In order to cope with these enormous challenges triggered by new technologies, the companies are continuously expected to reform their human resource management. Without exception, the hotel industry is trying to promote expertise of personnel management. The recent trends and conditions for personnel management in the hotel industry are to find more diverse ways of recruitment and retainment of qualified human resources, to transform the pay system form rigidity into a new and flexible one such as performance-related pay system, to make labor-management relations more cooperative, to create more open and democratic working atmosphere. In the process of implementing innovation and reform, tackling challenges in the digital age, above all, the hotels should try to cultivate originality and creativity of their workers harboring more generous attitude towards differences among workers and some failures made by them. Secondly, the hotel industry should foster well-educated human resources with expertise who can share and skillfully utilize new information and knowledge, thus contributing to the company making a good profit. If the hotels are to secure more competent workers with expertise, they should respect each workers individuality and provide a good atmosphere where the workers can cultivate their originality and study themselves. And thirdly, the hotels should nurture highly-qualified workers who can even make up for the employers shortcomings. Fourthly, they should uplift the workers ability to deal with e-commerce. Fifthly, they should get the workers equipped with a variety of knowledge. Sixthly, they should improve and make a full use of potential capacity of women workers. Seventhly, they should encourage the workers to learn foreign languages by which they will acquire an international way of thinking. Among foreign languages, English, Japanese and Chinese languages are strongly recommended.

Purpose: The object of our study was to examine the clinical significance of pediatric testicular microlithiasis(TM) as it relates to testicular cancer. Materials and Methods: Seven boys in whom TM was incidentally detected were followed for a mean of 51±44 months(range: 9-119 months) for testicular cancer surveillance. The average patient age at the initial diagnosis was 9.8±2.5 years. The frequency of coincidental TM detected on scrotal ultrasonography performed for all clinical purposes at our institution between January 1997 and January 2008 was investigated. Eighty-two testicular cancer patients and 1,006 noncancer patients underwent ultrasonography between 1997 and 2006, and these patients were divided into two age groups(children, age <15 years; adults, age ≥15 years) for purposes of analysis. Results: Of the seven patients followed solely for TM, none developed testicular cancer during the surveillance period. Coincidental TM seen on scrotal ultrasonography was significantly higher in the testicular cancer patients than in the noncancer controls(11%(9/82) vs. 3.5%(36/1,006), p<0.0001). According to the age groups, TM was found in 6% and 5.8% of the testicular cancer patients and the noncancer controls, respectively, in the children’s group, whereas in the adult group, 11.6% and 3.3% of the patients in the respective groups were found to have TM. Conclusions: The incidence of testicular cancer development in children with incidentally detected TM was very low, and the incidence of coincidental TM in children with testicular cancer did not differ from that in the noncancer control patients. However, the significantly higher incidence of TM accompanying testicular cancer after puberty may suggest an association of the two pathologies, which would then mandate cancer surveillance in cases of incidentally detected TM in this age group.

An On-line Algorithm to Search Minimum Total Error for Imprecise Real-time Tasks with 0/1 Constraint

송기현 한국멀티미디어학회 2005 멀티미디어학회논문지 Vol.8 No.12

The imprecise real-time system provides flexibility in scheduling time-critical tasks. Most scheduling problems of satisfying both 0/1 constraint and timing constraints, while the total error is minimized, are NP complete when the optional tasks have arbitrary processing times. Liu suggested a reasonable strategy of scheduling tasks with the 0/1 constraint on uniprocessors for minimizing the total error. Song et al suggested a reasonable strategy of scheduling tasks with the 0/1 constraint on multiprocessors for minimizing the total error. But, these algorithms are all off-line algorithms. On the other hand, in the case of on line scheduling, Shih and Liu proposed the NORA algorithm which can find a schedule with the minimum total error for a task system consisting solely of on-line tasks that are ready upon arrival. But, for the task system with 0/1 constraint, it has not been known whether the NORA algorithm can be optimal or not in the sense that it guarantees all mandatory tasks are completed by their deadlines and the total error is minimized. So, this paper suggests an optimal algorithm to search minimum total error for the imprecise on-line real-time task system with 0/1 constraint. Furthermore, the proposed algorithm has the same complexity, , as the NORA algorithm, where N is the number of tasks.

In 1989, a new male sterile mutant (MS216) was found on the Breeding and Research Station of Hungnong, which is assumed ofr cytoplasmic male sterility. This experiment was performed to study on the histological differences between the CMS line derived from MS216 ans AS10 which is genic male sterile line. The results were summarized as follows. 1 In histological observation microspore degeneration of GMS line began around dyad stage. However, in anther of CMS line derived from MS216, it was observed to begin around tetrad stage. 2 In anther of GMS line, severe hypertrophy was observed in their tapetal layer from dyad stage and the trace of tapetum remamed until blooming stage In anther of CMS line, hypertrophy in their tapetal layer was also observed at tetrad stage. But, it disappeared prematurely after microspore stage. 3 In anther of CMS line, shrinking up of the anther locule was prevailing phenomena, but it was not observed in GMS or MF line.

관광동기에 따른 관광행동이 지각된 가치에 미치는 영향

송기현,최현실 관광경영학회 2019 관광경영연구 Vol.87 No.-

This study intends to examine tourist behavior in a tourist site with the classification of a positive tourist behavior and a negative tourist behavior. The study develops a model that explains how tourist motivation influences tourist behavior, how perceived value is influenced by tourist behavior and how they influence to satisfaction. The participants were 387 adult tourists who had traveled over the last two years from the current year 2017. The study used SPSS 22.0 for Window statistical package for empirical analysis. To accomplish the research goal, 22 hypotheses were developed. 18 hypotheses out of 22 hypotheses were accepted. The hypotheses testing outcomes are summarized as follows. First, as to the hypotheses “tourist motivation significantly influences to tourist behavior”, Tourist site visiting motivation was not influential to negative tourism motivation, tourist site attraction negatively influenced on a negative tourist behavior. That is, the higher tourist site attraction was the lesser the negative tourist behavior was. Thus, it is recommended to create unique and entertaining contents in a tourist site. Second, as to the result of “tourist behavior is influential to perceived value” showed that a positive tourist behavior was influential to perceived value. A negative tourist behavior was not influential to emotional value, and it negatively influenced social value and positively on functional value. That is, when negative tourist behavior was conducted people tend not to feel happy nor perceived that they had a good memory after the tour. The more negative tourist behavior the lower social value was. That is, tourists might recognize that a negative tourist behavior was not matched to one's identity or self-image. The limitation of this study lies in response reliability, because the personal inquiry asks about a negative tourist behavior that may cause respondents hesitant to reply. A future study may provide models with higher explanatory power with more influential variables if it overcomes such limitation.
