  • Recently, Expectation Area-based Real-time Routing (EAR2) protocol has been proposed to support real-time routing in wireless sensor networks. EAR2 considers the expectation area of a mobile sink and uses flooding within the expectation area. However, flooding leads to excessive energy consumption and causes long delay against real-time routing. Moreover, since EAR2 uses single path to the expectation area, it is difficult to support reliable routing in sensor networks with high link failures. Thus, to overcome these limitation of EAR2, this paper proposes a reliable and real-time routing protocol based on virtual grids and multipath for mobile sinks. To support real-time routing, the proposed protocol considers expectation grids belonged to the expectation area. Instead of flooding within the expectation area, the proposed protocol uses multicasting to the expectation grids and single hop forwarding in an expectation grid because the multicasting can save much energy and the single hop forwarding can provide short delay. Also, the proposed protocol uses multipath to the expectation grids to deal with link failures for supporting reliable routing. Simulation results show that the proposed protocol is superior to the existing protocols.

  • The purpose of this study is to provide the necessary data for the effective performance of school nurse's work by comparing with the recognition and expectation on school nurse's work by the students and their teachers in school settings. The sample of this study was consisted of the 441 students and 535 teachers in Suwon. The data were collected by means of a structured questionnaire from 24th, Sept, to 29th, Sept. 1990. The collected data were analyzed utilizing SAS/PC program for percentage, frequency, mean, standard deviation and chisquare test. The major findings of this study were as follows: 1. The result of analysis in recognition on school nurse's work. There is no statistically significant difference 'depending on teachers' school level, sex, age and career with school nurse(P>0.05). The students show significant difference on their school level and sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest recognition and school environment management has the lowest recognition. 2. The result of analysis in expectation on school nurse's work. There is statistically significant difference depending on teachers' and students' school level: the order of expectation is elementary, middle, and high school(P<0.05). In the result of comparison with students' and teachers' expectation in the same school level, there is significant difference only in elementary school(P<0.05). However, there is no statistically significant difference depending on teachers' sex, age, career with school nurse and students' sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest expectation and school environment management has the lowest expectation. Synthesizing the result of the study, we can have the conclusion like following. First, students' recognition on school nurse's work is lower than teachers' because most of school nurse's work is performed through their homeroom teachers or other teachers. That can be the limitation for students to recognize school nurse's work. So, there must be a chance of regular meeting between school nurse and students to perform school nurse's work effectively. For this. we must change our educational system and make school nurse charge regular lesson. Second, in each area of school nurse's work, both students' and teachers' recognition and expectation about the area of school environment management has much lower score than the other areas. This indirectly shows the school nurse don't do the work of the area actively. So, school nurses must make an effort to do the work of the area actively. And we must enforce the education of this area in education for new school nurses or re-education for school nurses.

  • Objectives : The purpose of this study was to grasp association with dental hygienists' job expectation through correlation between curricular subjects for the department of dental hygiene and job. Methods : It carried out convenience sampling of dental hospitals where are located in Capital Area, and then conducted a self-administered questionnaire survey targeting 274 dental hygienists who are working here. The statistical program was analyzed by using PSAW 18.0. Results : Research subjects' 60.2% experienced turnover. Its reason accounted for 31.7% with the working condition. As a result of examining difference in experience of turnover according to dental hygienists' individual characteristic and working form, the significant difference was shown in age, marriage, annual salary, working institution, and career. In consequence of confirming association between curricular subjects and job, the majority showed high correlation. However, the correlation with oral physiology, clinical dental hygiene, and dental clinics showed low correlation as the insignificant variable. Conclusions : As a result of this study, the high correlation between curricular subjects and job can be considered to reflect dental hygienists' job expectation. On the other hand, the working condition, professional sense, and turnover experience, which are factors related to dental hygienists' job expectation, were indicated to fail to meet job expectation.

  • This study investigates the influence of self-efficacy in purchasing clothes in the consumer satisfaction formation process. A survey was conducted on 300 adults living in the Seoul and Gyeonggi area and 231 completed questionnaires were used for analysis. The survey questionnaires measured the respondent's self-efficacy in purchasing clothes, expectation, perceived performance, expectation confirmation, and satisfaction level. The data were analyzed by moderated regression analysis. The results are as follows. First, for apparel products, perceived performance, and expectation confirmation have a direct effect on consumer satisfaction, while expectation has no direct effect on consumer satisfaction. This finding agrees with the results reported in a previous study on consumer goods with low ambiguity in assessing products and services including sneakers, underwear, cereals, and financial services. Second, the lower the self-efficacy in purchasing clothes, then the increased effect of the expectation confirmation that influences consumer satisfaction. However, the self-efficacy in purchasing clothes did not show any moderating effect on the perceived performance affecting the consumer satisfaction. The self-efficacy in purchasing clothes seems to have a moderating effect on the consumer satisfaction formation process by affecting the ambiguity in pre-purchase product assessment and not in post-purchase product evaluation.

  • The purpose of this research is to investigate the characteristics of big data-based fashion shopping (BDFS) application, perceived usefulness, and expectation confirmation that influence the continuous usage intention of BDFS application users based on the expectation-confirmation model. A survey was conducted with female consumers in their 20s, who are living in Seoul and Incheon area and have used BDFS applications, A total of 182 responses were used for the data analysis. Five hypotheses were proposed, and regression analyses were conducted to test those hypotheses. The results indicated that the users' perceived usefulness increased with the increase of accuracy and personalization characteristics of the app and the expectation confirmation. The result suggested that it is essential to provide accurate information for users to feel useful and to develop the personalized offerings and services which can be the biggest strength of the big-data based mobile fashion store. It was also found that continuous usage intention increases with increased perceived usefulness and expectation confirmation. This result suggests that expectations can play a critical role in perceiving the usefulness of BDFS applications and the user's expectation confirmation also significantly affected the users' continuous usage intention.

  • The purpose of this paper is to estimate a probability to visit the Yeosu Aquarium with an ordered logit model. Ordered logit model is affordable to estimate the probability when the dependant variable represents likert-type scale. The estimated results are as follows. The more income induces the visiting-expectation. The experience for another aquarium and the visiting-expectation for the Yeosu EXPO are contributed to the visiting-expectation for the Yeosu Aquarium. The needs to visit the Yeosu Aquarium is low in Kyoungsang area and Seoul-Kyounggi-Incheun Metropolitan area. This is related to the Aquarium facilities, which were established in each area. In average level conditions regarding to all independent variables the probability to visit the Yeosu Aquarium is calculated to 15.75%. However, the probability to visit to the Yeosu Aquarium is decreasing according to the change of an admission fee.

  • This study explored the effects of expectatioin, performance, and disconfirmatoni on satisfaction of theme park users. Everland was chosen as the study area, and 260 users were selected by the nonprobability sampling. In expectation disconfirmation paradigm, expectation should be measured before purchase, and performance, disconfirmation and satisfaction should be measured after purchase. An entrance survey was done to measure expectation, and an exit survey to measure performance, disconfirmation, and satisfaction. Maximum likelihood method was used to estimate structural equation model by the LISREL 7.2. Performance had the most significant effect on satisfaction among three variables. The satisfaction of theme park users depends largely on it, therefore, the consideration of visitors' performance should e essential for managers.
