After 2000 year, cremation rate have increased constantly as public concepts change, while grave area where occupy over 1% of South Korea territory also increase steadily. The purpose of this study is to establish the foundation of maintenance and implementation of temporary burial system introduced in 2011 through research on the actual condition. In this paper, improvement of guideline for the study area and prototype of across the board burial mound survey are offered through carry out research on the five case study area. In addition effective way for nationwide project also is suggested.

Objectives: The purpose of this study was to examine the awareness and actual condition toward nonsmoking policy in Korean adult. Methods: A self-reported questionnaire was completed by 306 Korean adults between 20 to 60 years old from April 27 to May 26, 2015. The questionnaire consisted of general characteristics of the subjects, smoking status(3 items), nonsmoking status(9 items), and nonsmoking policy(7 items). Data were analyzed using SPSS 18.0 program. Results: Those who had alcohol consumption or not tried to participated in the nonsmoking program(p<0.05). There was a significant difference between nonsmoking education, cost of the nonsmoking education, and intention to stop smoking. Alcohol consumption is closely related to smoking and the appropriate approach to nonsmoking campaign must be done carefully on the basis of intention to stop smoking(p<0.05). Conclusions: As the government prohibits smoking in the public place, it is important the smokers to stop smoking by themselves and help the smokers to practice nonsmoking in their free will.

The purpose of this study is to present a fundamental data for evaluating aircraft noise of building site development. By the field experiments and an predicted equal noise level contour using the INM program, actual condition in the building site development arranged district was investigated. In order to get the results, Analysis of factors effected on noise level, sound level on the rate of increase to aircraft demand and difference on the aircraft noise levels according to floor level in apartment house was carried out.

In the Well-being age, many people use a city park for rest deeply think and constitutional walk. The city park is located at near side by traffic road in urban. Citizens are not satisfied with it's fuction as a haven of peace due to road traffic noise. Thus, this study is for a research on the actual noise condition of a city park in Nowon go. This study uses a prediction method called ASJ-model in order to calculate PWLs of road traffic noise. Using calculated PWLs, noise levels in a park are predicted and compared with measured values.

This study deals with actual commuting distance and influence of risk factors depending on commuting distance and mode in order to reestablish actual commuting zone of primary school students. Data mining analysis(CHAID) was applied for this reestablishment using survey results from 6,927 primary school students in Seoul Metro. Six risk factors; convenience level of commuting path condition, convenience level of road crossing condition, vehicle speed on commuting path, segregation level between commuter and vehicle, congestion level of commuting path, and public security level and two mode; walking and cycle are considered in the analysis. As the results of CHAID analysis, commuting distance was divided into four zones; Internal Zone(0.491km under), External Zone(0.492 ~ 1.492km, 1.493 ~ 2.699km), Commutable Zone(2.70km over), and awareness level on safety is declined as commuting distance is increased. The risk factor affecting on safety is recognized differently by students depending on commuting distance and mode. For students commuting by walking, vehicle speed on commuting path and convenience level of commuting path condition are recognized as the prime risk factor within Internal Zone and Commutable Zone, respectively. For students commuting by cycle, convenience level of road crossing condition and vehicle speed on commuting path are recognized as the prime risk factor within Commutable Zone. Analysis results show that improved plan and program for commuting path for primary school students are required considering actual commuting distance and method.

Recently, autonomous robots which can achieve the complex tasks have been required with the advance of robotics. Advanced robot vision for recognition is necessary for the realization of such robots. In this paper, we propose a method to recognize an object in the actual environment. We assume that a 3D-object model used in our proposal method is the voxel data. Its inside is full up and its surface has color information. We also define the word "recognition" as the estimation of a target object's condition. This condition means the posture and the position of a target object in the actual environment. The proposal method consists of three steps. In Step 1, we extract features from the 3D-object model. In Step 2, we estimate the position of the target object. At last, we estimate the posture of the target object in Step 3. And we experiment in the actual environment. We also confirm the performance of our proposal method from results.

The purpose of this study is to explore the trend in insulation resistance values according to temperature and overcurrent by conducting an investigation on the actual condition and experiments on the electrical wiring during the melting furnace process. In addition, the Arrhenius equation is used to determine whether temperatures in the furnace operating process can be applied to the actual field. In the investigation of the actual condition, the insulation resistance started to decrease seven years after replacement, even though cables in oil pump A were replaced in 2010. Both the experimental and theoretical values of the insulation resistance obtained using the Arrhenius equation decreased with an increase in temperature. Errors in insulation resistance (MΩ) values between tests and the Arrhenius equation ranged from ±2 to ±10, demonstrating a high similarity. Results revealed that when the insulation resistance cannot be measured in a manufacturing workplace (quarterly analysis), it can be estimated by partially applying the Arrhenius equation.

This paper is concerned with the performence of a steam reformer for 25kW class MCFC, which is compared with the theoretically calculated results at various operating conditions. The theoretical $H_2$ production amount and $CH_4$ conversion rate are calculated with variations of temperature and steam/carbon (S/C) ratio using fortran program, and the actual values are measured from flowmeter and gas chromatography. As a result of the comparison of theoretical and actual values, the theoretical $H_2$ production amount is calculated by $24.4m^3/hr$ at the normal operating condition(LNG $9m^3/hr$, S/C ratio 5, absolute pressure $2.77kg/cm^2$, $610^{\circ}C$), but the actual production amount is only $19.4m^3/hr$, which is 79.5% of the theoretical value. Nevertheless, at the normal operating condition, the reformer for 25kW class MCFC performed well for a 2,100 hr long run operation, constantly producing $H_2$.

국가 정보화 정책이 중점 추진되면서 1990년대 중반 이후 정보통신 이용자수가 급격히 증가하고 있으며, 10대 청소년 계층의 90%이상은 일상생활에서 정보통신을 이용하고 있는 것으로 나타났다. 정보통신 이용의 급격한 증가는 우리 사회를 의사소통이 신속하고 편리한 커뮤니케이션의 장으로 변모시켜 사회 각 분야의 생산성과 효율성을 높여주고 있다. 그러나 그에 따른 각종 역기능도 심각하게 나타나고 있어 사회 문제로 대두되고 있다. 특히 10대 청소년 계층이 그 역기능에 가장 심각하게 노출되어 있는 것으로 나타나 대책마련이 시급하다. 따라서 본 연구에서는 초 중등학교에서 실시되고 있는 정보통신 윤리교육의 현황을 파악해 보고 학생들의 정보통신 이용 실태와 비교 분석함으로써 보다 현실적이고 효과적인 정보통신 윤리교육의 방향을 탐색하고자 한다.
