In this study, we derived seven customer value factors to evaluate the levels of service in wastewater utilities required by customers. Levels of service according to the customer value were categorized into environmental amenity, accessibility of wastewater service, affordability of wastewater charge, quality of wastewater service, health and safety of wastewater service provision, reliability and responsiveness of wastewater service provision, and satisfaction of customer service. To investigate the levels of wastewater service, questionnaires were prepared according to the customer value factors, and the questionnaire survey was performed with 800 adults in all over Korea including male and female samples. The comprehensive satisfaction score for the wastewater service was 57.5 points, indicating a slightly good satisfaction level. The detailed analysis of the result showed that the satisfaction level was high in the wastewater service accessibility and call center service provision but it was relatively low in the river water quality and nasty smell of wastewater. It was concluded that the quality of wastewater service and customer service satisfaction need to be elevated primarily in order to improve levels of wastewater service required by the customers.

This study aims to examine the reasons of changes in motivation of pre-service teachers who major in environmental education. Qualitative case study methods were adopted to collect and analyze data from six(6) pre-service teachers in environmental education department. Researchers conducted semi-structured interviews with them on the levels of motivation toward their studios. The study results are as follows. The levels of motivation toward their studies were shown differently by each of the pre-service teachers. Some of the pre-service teachers reported that their levels of motivation toward environmental education had changed since the college entrance. The reasons for the changes include 'suitability of environmental education to personal propensity,' 'college courses they took', and 'personal experiences.' Some of the pre-service teachers reported that the levels of motivation for their majors did not changed since he or she was pursuing other goals rather than being an environmental educator.

An interesting problem in capacitated supply chains is how to guarantee customer service levels with limited resources. One of the common approaches to solve the problem is differentiating service depending on customer classes. High-priority customers receive a better service at the cost of low-priority customers' service level. One of common criteria to determine a customer's priority in practice is whether he has made a reservation before arrival or not. Customers with a reservation usually receive service based on the time the reservation was made. We examine the effect this advance information of customer arrival has on customer service levels. We show the trade-offs between the leadtime and other system characteristics such as the proportion of high-priority customers. when the service level is high. We also suggest how to differentiate service using the asymptotic ratio of the service levels for both types of customers.

The present study explored whether the implementation of focused activities (intervention programme) can enhance 22 pre-service mathematics teachers' proficiency in solid geometry thinking level as well as change for the better their feelings in this discipline. Over a period of 6 weeks the pre-service teachers participated in activities and diversified experiences with 3D shapes, using illustration aids and actual experience of building 3D shapes in relation to the various spatial thinking levels. The research objectives were to investigate whether the intervention programme, comprising task-oriented activities of solid geometry, enhance mathematics pre-service teachers' mastery of their geometric thinking levels as well as examine their feelings towards this discipline before and after the intervention programme. The findings illustrate that learners' levels of geometric thinking can be promoted, entailing control on higher thinking levels as well as a more positive attitude towards this field.

In this study, I investigated how pre-service teachers (PSTs) proved three geometric problems by using Geometer's SketchPad (GSP) software. Based on observations in class and results from a test of geometric reasoning, eight PSTs were sorted into four of the five van Hiele levels of geometric reasoning, which were then used to predict the PSTs' levels of reasoning on three tasks involving proofs using GSP. Findings suggested that the ways the PSTs justified their geometric reasoning across the three questions demonstrated their different uses of GSP depending on their van Hiele levels. These findings also led to the insight that the notion of "proof" had somewhat different meanings for students at different van Hiele levels of thought. Implications for the effective integration of technology into pre-service teacher education programs are discussed.

The purpose of this study was to determine the relationship between the students' levels of involvement in school lunch service and their satisfaction levels with the service. A survey was conducted with $5^{th}\;and\;6^{th}$ grade elementary students eating school lunches. Out of 1,680 questionnaires distributed to the students from 14 schools, 1,254 complete questionnaires $(74.6\%)$ were analyzed. The questionnaire included two 5-point multi-item scales for measuring levels of involvement in and satisfaction with school lunch service, respectively. A factor analysis grouped 20 items measuring school lunch satisfaction into three factors: 'food satisfaction', 'nutrition & sanitation satisfaction', and 'service & environment satisfaction'. As a result of multiple regression analyses controlling the influence of such variables as students' grades, gender, school location, years and places of eating school lunches, students' levels of involvement in school lunch service was proven to be positively associated with levels of school lunch satisfaction overall, as well as satisfaction levels in regard to 'food', 'nutrition & sanitation', and 'service & environment', respectively. It was suggested that efforts such as nutrition education to increase students' levels of involvement in school lunches could be a useful strategy to improve students' satisfaction with school lunch service.

호텔기업은 양질의 서비스를 제공하기 위해 종사원의 행위에 보다 많은 관심을 가져야 한다. 호텔의 특성상 서비스품질은 종사원들이 어떻게 서비스를 수행하는 가에 달려있다. 즉 호텔종사원이 서비스 현장에서 신속하게 의사결정을 할 수 있는 시스템이 절실히 요구된다. 그렇게 하기 위해서는 종사원의 임파워먼트가 대단히 중요하다. 따라서 본 연구는 호텔종사원의 임파워먼트와 서비스제공수준의 관계를 분석하고 이들의 관계에서 직무만족과 조직몰입이 매개역할을 하는 가를 파악하려고 하였다. 매개효과의 조건충족에 대한 분석은 Baron 과 Kenny(1986)가 제시한 삼 단계의 매개효과 분석과정을 이용하였다. 235명의 호텔종사원을 대상으로 한 분석결과 설정된 가설은 모두 지지되는 것으로 판명되었다. 분석결과에 따르면, 임파워먼트는 직무만족, 조직몰입, 서비스제공수준에 영향을 미치는 것으로 나타났다. 또한 임파워먼트와 서비스제공수준의 관계에서 직무만족, 조직몰입 각각은 매개의 역할을 하는 것으로 검증되었다.

The purpose of this study is to examine the effects of gender role attitudes and family service utilization on self-esteem among single parents. This study used data from the seventh wave of Korean Welfare Panel Study and analyzed 90 single parents. Hierarchical multiple regression analyses showed that health status, economic situation, gender role attitudes, and non-monetary family welfare service had significant effects on single parents' self-esteem. Single parents who had higher traditional gender role attitudes show lower levels of self-esteem. Also use of a non-monetary family service increased the levels of self-esteem. However, use of a monetary family service was not significantly associated with the levels of self-esteem. The findings indicate that services and programs to promote single parents' gender role flexibility should be developed. Also, it is necessary to establish a service system to reduce multiple role stress among single parents.
