Mineral oil has been widely used as an insulating oil for electrical transformers for a long time, but the necessity of employing new insulation oil such as vegetable oil has been increased due to urgent needs for the biodegradability when it leaks and also for the thermal stability at a higher operation temperature. Although specific periods are required between the production and consumption, there are still short of the data to prove the insulation oils' storage stability depending upon various circumstances and their resources. Thus, this paper demonstrates the insulation oils' oxidation characteristics of both mineral and vegetable oils when each was exposed to different environments for 12 weeks. From this test, some properties including total acid number, water content and dielectric breakdown were changed under specific conditions and resources. Vegetable oils showed higher hydrophilicity and water saturation than those of mineral oils due to their molecular compositions. Under sunlight exposure condition, all insulation oils oxidized and changed their properties when exposing to the direct light, regardless of the resource used.

It is becoming increasingly important to make use of alternative energy source. because It is not able to rely on only fossil fuel for the recent increasing demand of energy consumption. With this situation, lots of studies for utilizing low grade energy such as industrial waste heat, solar energy, and geothermal energy have been conducted. The aim of this study is to predict the operation characteristics of working fluid by using performance analysis program (ThermoFlex) through the system analysis which is not mixing district return water but using ORC(Organic Rankine Cycle, hereinafter ORC) as a downstream cycle when accumulating district heating (hereinafter DH). In this study, We conducted the performance analysis for the case which has the district heating water temperature($120^{\circ}C$) and Flow rate of $163m^3/h$ (including District Heating return water flow), and examined several working fluid which is proper to this temperature. The case using R245fa (which is the best-case) showed 269.2kW power output, 6.37% efficiency. Additionally, Cut down on fuel was expected because of the boiler inlet temperature increase by being Formed $57.3{\sim}85^{\circ}C$ in a temperature of district heating return water, depending on a pressure change of a condenser in ORC system.

The aims of this study is to find the facts of regional inequality and to suggest the desirable location of educational facilities and its related policies through the analysis of the distributional characteristics of high schools in Daegu viewing from public service facilities. The results are as follows. As of 2000 year, there are 76 high schools in operation in Daegu. The number of private high schools is more than that of national public ones in terms of their founders, and the number of general high schools outnumbers that of vocational high schools by their operational types. As a whole, the distribution of schools in Daegu is closely related to the population distribution(redistribution). In case of high schools, it shows that there is severe unevenness between demand and supply of educational facilities per district. The regional inequality of school facilities is getting worse by transfer and new establishment; inter-district transfer is mainly caused by the redistribution of population while intra-district transfer is accelerated by the pressure on better use of land. Recently there is a tendency that schools are newly established by public sector(national public schools) rather than by private sector(private schools). And the predilection or avoidance of a certain area in the process of choosing the site for transfer or new establishment of schools lead to inequality of education opportunities per district. In conclusion, the educational facilities should firstly be placed in the practice of public service facilities in terms of public welfare as well as the convenience of residents and regional inequality. Consequently, both construction of new high schools and the relocation of existing high schools have to be further activated. To achieve them, the role of public actions is particularly more important than that of private ones.

The purpose of this study is to analyze high school students' understanding levels about earth science terms written in Chinese characters according to learners' characteristics. In order to investigate how the responses vary according to their characteristics, first of all, proper scientific terms are selected, and then corre sponding questions about them are offered as subjects, which consists of a Korean characters type, a picture type, and a Korean and Chinese characters type. During paper test and interview, the questions are given to fifteen students from general high schools in Jecheon, Chungbuk Province. The results of the study are as follows; Students in formal operation level and field-independency answered very well and also the terms of Chinese characters type and picture type improve the students' understanding and memorization. Generally, Chinese characters have more positive influence on their learning than the negative. Therefore, in general, it seems that it's more effective to explain the sound and meaning of terms in detail and to give learners enough time to draw a picture about each term by themselves when scientific terms are delivered to students in Chinese characters in class.

The purpose of this study is to explore the main characteristics regarding of implicating competence-based curriculum in Finland's home economics curriculum by analyzing curriculum documents and related literature. The research findings are categorized into four main characteristics. First, home economics in Finland belongs to the 7-9 grades. The key content areas are composed of 'food knowledge & skills and food culture', 'housing & living together' and 'consumer & financial skills' at an integrated approach. Secondly, the subject competences of home economics are not presented; however, the general objectives of transversal competences are defined in Finland's curriculum document. Transversal competences describe the aspects of the objectives that are emphasized in grades 7-9 and strengthens the connectivity with each subject. Thirdly, the objectives of home economics included in the instructions in Finland consist of a content system that links learning skills, content areas, and transversal competences. Both learning skills as a role of subject competences and content areas as objectives support teachers who restructure an curriculum. Fourth, in terms of achieving subject objectives, the assessment criteria in Finland home economics is to evaluate the achievement of good knowledge and skills through actual performance. Based on the research findings, the main features of the revised curriculum in Finland include encouragement of flexibility in education systems and learner's uniqueness in schools. If the implementation of subject competences in home economics is to be strengthened, it is necessary to intergrate the knowledge and competence, require a curriculum system for implements' subject competence, carryout assessment as learning to learn, and facilitate school community and teacher community for deeper co-operation.

There is an increasing interest in the development of rechargeable batteries suitable for use in both hybrid electric vehicles and energy storage systems that require higher charge & discharge rates, bigger battery sizes and increased safety of the batteries. Spinel-type lithium titanium oxide ($Li_4Ti_5O_{12}$) as a potential anode for lithium ion batteries has many advantages. It is a zero-strain materials and it experiences no structural change during the charge/discharge precess. Thus, it has long cycle life due to its structural integrity. It also offers a stable operation voltage of approximately 1.55 V versus $Li^+/Li$, above the reduction potential of most organic electrolyte. In this study, Ru added $Li_4Ti_5O_{12}$ composites were synthesized by solid state process. The characteristics of active material were investigated with TGA-DTA, XRD, SEM and charge/discharge test. The capacity was reduced when Ru was added, however, the polarization decreased. The capacity rate of $Li_4Ti_5O_{12}$ with Ru (3%, 4%) addition was reduced during the charge/discharge precess with 10 C-rate as a high current density.
