There were little available data of vehicular incendiary fires. We investigated fires by inflammable gasoline and papers. cloths in the interior and exterior of vehicles. Fires in the interior and exterior of vehicles were carried out under the several conditions by incendiary methods and vehicle's windows. We knew that dominant factor of combustion is direction of wind at that time in vehicle's fire. And we knew that the other mark of combustion pattern in vehicle's fire could be a clue for solving the problem in discerning the place to which we sotted fire between the general fire and arson.

Partial discharge pulse shapes from variable PD (partial discharge) sources sustain many characteristics such as types of PD. Ultra high frequency antennas have wide bandwidth from 30KHz to 2㎓. Therefore, signals taken from a UHF antenna have important attributes (rising time, falling time, shape factor, etc.) for electromagnetic sources, such as PD sources. We investigated PD pulse shapes from several PD sources using a UHF antenna and the results were used for classification of PD sources. Features for discrimination are extracted from frequency distribution and LPC (Linear Prediction Coefficient) of time signal. RBFN are used for investigating the possibility of classification of multi-PD sources.

The aim of this study is to derive design guidelines which improve the life satisfaction of elderly residents at welfare facilities. There are many factors affecting on satisfaction with life of the institutionized elderly, but this study focuses on architectural factors. So, two factors are derived, the first factor is the behavier facilitation and the second is the social-interaction. In this study, the behavier facilitation, which was considerd by elderly's physical feature, means safety, discrimination and adaptability. The social interaction, which was considerd by elderly's psychological feature, was supported by homogeneous, approximate, privacy, territoriality, personalization, and control.

The signals of the eddy current testing(ECT) for the examination of the steam generator(SG) tubes in the nuclear power plant(NPP) determine the existence, size, and kind of defects using the variation of impedance signals when a testing coil, driven by alternating current, passes through the SG tube contains defects. The aim of this paper is building a database of the RPC probe signals on the basis of the sizes variation of defects and frequency variation of probe. In this paper 3-D numerical analysis of the ECT signals using the finite element method is performed. Through this study, it is shown variation of magnitude and phase of impedance according to variation of defect size and frequency. From the result of this paper, we can obtain the information which is useful in defect discrimination of SG tube in nuclear power plant.

In this study, investigation of spent fuel was performed using six group delayed neutron parameters. Three used fuels (F1, F2, and F11) which are burnt over the years in the core of Missouri University of Science and Technology Reactor (MSTR), were investigated. F16 fresh fuel was used as plutonium free fuel element and compared with irradiated used fuels to develop burnup and Pu discrimination method. The fast fission factor of the MSTR was calculated to be 1.071 which was used for burnup calculations. Burnup values of F2 and F11 fuel elements were estimated to be 1.98 g and 2.7 g, respectively. $^{239}Pu$ conversion was calculated to be 0.36 g and 0.50 g for F2 and F11 elements, respectively.

Our nation has a problem with discrimination of income distribution and inefficient of resources distribution caused by real estate price rising from a sudden economy growth and industrialization. Specially, in recent years, there is a great disparity of condominium price between the north and south of the Han river. Because the housing price is deciede by the immanent value of a house and neighborhood effects of the regional where the house is situated, the housing price is occurred difference. In this study, I analyzed the differences of housing price determinants about condominium developments in the old and new residential areas, and found the important factors that affect the condominium price using Structural Equation Modeling(SEM) The purpose of study is to analyze the influence of various factors of housing price. Also, this study tried to predict real estate market and to establish previous effective real estate policy.

Disability Discrimination Act(DDA) is generally recognized as the institutional frame to realize social model of disability. However social model is not automatically realized via the enactment of DDA. The realization of social model is influenced by various factors among which the definition of disability in DDA is very important factor. Paradoxically definitions of disability based on social model may push DDA into contradictory situation. This is caused by the fact that on the one hand definitions of based on social model exclude impairment and on the other hand they mixes characteristics and treatment. Because of these, when definitions of disability based on social model is reflected into definitions of disability in DDA, they may not be helpful to realize social model against original intention of advocates of the model. We can consider two approaches to resolve this paradox; one is to partially reform current definition of disability in DDA, the other is to totally amend current definition of disability. The former may pragmatic and worth to pursue but it cannot solve fundamental problems and may cause some new problems. The most consistent resolution with social model is to amend current definitions of disability into radically new one which excludes substantial limits and definition of disabled person from definition of disability. This new definition may called characteristics based definition or impairment based definition. Some people may think this new definition as one based on medical model but it is not. What we need is not to carve definition of disability based on social model into DDA but to make institutional frame for DDA to operate without contradictions and to develop social model of both impairment and disability. This model which does not exclude impairment could takes part in realization of the social model disability.

The purpose of this research is to analyze male oriented military culture and gender discrimination. It examined whether the experience of military service would affect the attitude of Korean college students, gender role identity, and sexism by classifying 317 college students into three groups; males who have completed military service, males who haven't completed military service, and a female group. Research results are as follows: First, in general military experience did not enhance awareness of gender identity nor affect attitudes toward gender discrimination, but significantly enhanced masculinity in some males who completed military service was a major factor in strengthening masculinity and benevolent sexism. Second, males who completed military service and women had a more positive view of the military than males who had yet to serve in the military. Third, regardless of military experience and gender, military experience was perceived to enhance benevolent sexism towards women. Fourth, all three groups showed a strikingly positive correlation in hostile sexism and benevolent sexism. However, they did not show a significant difference in the correlation of groups. Tough these results indicate that deep-rooted gender discrimination in Korean society is enhanced by military experience, it also confirms the significance and impact of the reality of the military ideology.

This study suggests methods of assessing scientific creativity and developing items, which can be achieved when both earth science knowledge and general creativity are applied at the same time. According to the results of this study, the cognitive ability gaps between creativity and scientific creativity were clearly defined by the terms' operational definition. Four factors in the Subcategory Of Scientific Creativity-fluency, flexibility, elaboration, and originality-were selected, and the possibility of developing items out of these factors was discovered. The operational definitions of the four factors were given and the criteria for assessment and scoring were set. The validity, reliability, discrimination, and difficulty, which were the conditions required for the assessment instruments, were verified through three field trials of inputting the assessment instruments for scientific creativity. The assessment instruments were composed of 8 items with 2items for each factor. The average item fitness index obtained was 0.99, Cronbach , the item inter-consistency was 0.79,the inter-rater reliability of each item was 0.78, the inter-rater reliability of each factor was 0.75, the item discrimination power was 0.19, and the item difficulty was 0.00. Because the results were within the permitted limit of the conditions required for assessment instruments, the assessment instruments developed for scientific creativity in this study can be said to be very favorable.
