  • The primary purpose of this study is to suggest the policy for the effective utilization of empty classrooms in elementary school. The empty classroom in this study means the classroom that is not used now since the number of students decreases, but can be usable for other needs in future. The following results are obtained through this survey; 1) about forty percent of classrooms are empty classrooms, 2) the ratio of empty classrooms is higher in urban area than rural area, 3) the smaller the size of classroom is, the higher the ratio is, and 4) 56.5% of the schools have one to three empty classrooms and 30.0% have four to six empty classrooms. In conclusion it is suggested that 1) the reutilization plan of empty classrooms be established according to particular situation of each school, 2) the government develop the guidelines for reutilization and administrative procedures for renewal, 3) the reutilization plan be established from the view point of the quality improvement of schooling, and 4) the enlargement and rearranagemt of learning space be considerd when reutilization is planned.

  • The purpose of this study was to examine the effect of discrimination on thereutilization intentionfor dental services among patients who visited the dental clinic. The questionnaire was administered to 432 patients aged 20 years or older who visited Dental Clinic in J city, Chungcheongbuk-do. Day to March 31, 2015, and the following results were obtained. The important variables that affected the reutilization intention were quality of medics, kindness, hospital image, convenience, service value and discrimination of dental care service. These variables explained 78.2% of the aggregate. Thehigher the quality of service value, medics, environment facilities, convenience, kindness, and hospital image, the more significant was the relevance with reutilization intention. As well as high-educated respondents, ones with monthly household income amounted to 4 million won, group of white-collar job, people who visited for implant treatment and ones by introduction of acquaintances. Therefore the dental care service providers are required to take effortsto recognize the discrimination and to reduce it through good quality of dental care service.

  • A series of experiments were performed to study the influence of the following parameters on the physical traits and composition of swine manure compost: (1) addition of magnesium (Mg) at a molar ratio of 1.2 with respect to $PO_4$, and (2) reutilization of compost containing $MgNH_4PO_4{\cdot}6H_2O$ (magnesium ammonium phosphate, MAP). Three independent batch tests were conducted for replication: batch test I-control (C) and Mg added (T), batch test II-C, T and compost recycle ($T_{R1}$), and batch test III-C, T and compost recycle ($T_{R2}$). Magnesium addition and compost reutilization had no adverse effect on the degradation of organic matter. Reuse of the compost, however, had a clear effect on the total nitrogen (TN) and total phosphorus (TP) contents in the final compost. Repeated compost reutilization as a bulking material was resulted in composts rich in N and P. Upon adding the Mg supplement to the composting materials, the ortho-phosphate (OP) to TP ratio decreased due to the MAP crystallization reaction. The decrease in the OP/TP ratio and the increase in the TP content of the compost indicate that water-soluble phosphate is converted into a slow-release phosphate by the formation of crystals during composting. X-ray diffraction analysis of the irregular shaped crystals in the compost indicated that they are MAP crystals and that the crystallization of MAP begins immediately after the addition of the Mg supplement. The Mg addition to composting materials and the reutilization of compost as a bulking material would be a practical means to conserve nutrient content.

  • Route discovery in wireless mobile networks requires a considerable amount of resources due to the mobility of the hosts. Therefore, it would be wise to utilize the effort already invested in existing paths. This paper proposes an efficient way to reuse, whenever possible, existing paths when a new path is being established. In our proposed algorithm, called Route Reutilization Routing (RRR), the reusability is accomplished by the notion of the dynamic proactive zones (DPZ), through which nearby existing path information is disseminated. By utilizing the information stored in DPZs, RRR can achieve considerable savings over other on-demand routing algorithms that use flooding. The unique feature of the proposed algorithm is that DPZs are created and destroyed dynamically around the existing paths, whereas proactive zones are formed around the nodes throughout the network in other route finding algorithms. Even though using DPZs may not result in the shortest path between source and destination, simulation results show the considerable reduction in traffic needed to find a path and therefore increases the available bandwidth for data transmission.

  • Purchasing used school uniforms is to reduce environmental pollution and expenses, and to enhance a feeling of wearing satisfaction for school uniforms by improving size fitting. In order to improve reutilization of used school uniforms, uniform purchasing behavior, awareness of the reutilizing markets of used school uniforms, and the running conditions of reutilizing markets of used school uniforms were analyzed through the survey. The subjects are 741 students of middle and high schools in Seoul and Kyeonggi Province in this study. The results are as follows. First, the better-fitted uniforms students wear, the higher satisfaction they feel. Therefore, it is desirable for students to wear the uniforms which are well fitted for each student. Second, the higher aware of environment students are and the more environmental preservation behavior they do, the higher awareness of wearing used school uniforms they are. In order to enhance students' awareness of reutilizing markets of used school uniforms, it is important to educate students about the environment systematically and to promote recycling events. Third, the reasons for not purchasing used school uniforms are difficulty in access to the repurchasing market and the sanitary problem. Therefore, it is suggested that environmental education which boosts students' awareness of environment and reutilization events should be held to make reutilizing markets of used school uniforms vigorous. Moreover, it is necessary to make reutilizing markets easy to access and improve cleaning and repairing system.
