본 연구는 기후변화에 대응하는 의생활 실천을 위한 중학교 가정과 의생활 교수·학습 과정안을 개발하는 것을 목적으로 분석, 설계, 개발, 평가의 단계로 진행하였다. 기후변화 관련 문헌 고찰을 통해 '현상과 원인, 영향(환경적·경제적·사회적), 대응(완화·적응)'를 기후변화의 교육 내용 체계로 선정하고, 이를 가정 교과 의생활 단원의 분석 준거로 활용해 2015 개정 중학교 「기술·가정」① 교과서 6종을 자료유형(읽기 자료, 그림 자료, 활동 자료) 및 의복사용주기(생산, 구매, 사용, 폐기)에 따라 분석하였다. 교과서 분석을 통해 추출한 의생활 영역에서의 기후변화 내용 요소를 바탕으로 다양한 교수·학습방법과 수업 자료 및 매체를 활용하여 총 12차시의 기후변화 대응을 위한 가정 교과 의생활 교수·학습 과정안을 개발하였다. 교수·학습 과정안은 기후변화의 현상과 원인, 영향, 대응에 대한 통합적인 이해를 바탕으로 기후변화의 심각성을 학생 스스로 깨닫고, 이를 의생활 행동 실천으로 이어 가정과 사회에 긍정적 영향력을 행사할 수 있도록 구성하였다.

In recent years the demand for energy conservation has resulted in "tight" buildings with decreased air change rates. Although a reduction in air change rates can save energy utilized for heating or cooling of dwellings, there is an increased concern for the air quality of the indoor environment where individuals spend most of their lifetime (Schwab et al., 1990).., 1990).

In this paper we propose a new fault detection and isolation (FDI) method for those faults of parameter change type. First, we design a residual generator based on the ${\delta}$-operator model of the plant by using the stable pseudo inverse system. Second, the parameter change is estimated by using the property of the block Hankel operator. Third, reliability with respect to stability is quantified. Fourth, the limitations for the meaningful diagnosis in our method are given. The numerical examples demonstrate the effectiveness of the proposed method.

Natural frequencies of the transverse vibration of beams with step change in cross-section are obtained by using the asymptotic closed form solution. This closed form solution is found by using WKB method under the assumption of slowly varying properties, such as mass, cross-section, tension etc., along the beam length. However, this solution is found to be still very accurate even in the case of large variation in cross-section and tension. Therefore, this result can be easily applied to many engineering problems.

Recently the building is introducing the indoor water space. Thermal environment change with the introduction. Consequently, this study shows how water space in the public facility affects the indoor environment. We had put our experiment to measure the humidity and temperature differences in different distances of water space. The result of this study is as follows. First, We found that even though there's a water space, it makes no big change in temperature by different distance. The temperature was only maintained by a cooler. Second, As there's a water space, the humidity was affected by within 1.5 m of it. Through our experimental result, we have started our study to make a water space effective.

In this work, a numerical model is proposed for the relation between the magnitudes and the depth residual stress with the velocity of Rayleigh wave. Three cases, stress-free, uniform stress and layered stress, are investigated for the change tendency of the Rayleigh wave speed. Using the simulated signal with variation of residual stress magnitude and depth, investigation of the parameters for fitting residual stress and velocity change are performed. The speed change of Rayleigh wave shows a linear relation with the magnitude and an exponential relation with the depth of residual stress. The combination of these two effects could be used for the depth profile evaluation of the residual stress.

This paper discusses some variables of innovation arised in the Mathematical Curriculum reform, This means that we should consider the curriculum change based on those variables so that the Mathematical Curriculum could be created on our culture, need of industrial society and nation's system. Those variables could be described as follows. (1) Extension of Compulsory Education (2) Needs of industrial society (3) Change of School environment (4) Integration of School subjects The research method used in the study was the interview-analysis method which the researcher firstly send the questionnaire and then have interviews with the target people. This study also suggests informally a possible solutions of problem that current mathematical curriculum is faced. Those solutions include the change of mathematics syllabus based on the adaption toward the real problems arised in real world.

Photovoltaic System does military exploit that use heliometer light and is clearness source of energy. Photovoltatic System is no noise, shock among is several Substitute energy and after establishment maintenance having simple special quality, is applied in many fields. However, while Photovoltatic System is having these advantage, but react sensitively in effect of Photovoltaic scanning Quantity, temperature change etc.. surrounding environment, when did not satisfy condition, express indefinite output price. Consider voltage$\cdot$current output measurement value and temperature revision calculation by temperature change of existing photovoltaic system and change of output price of when did Simulation analyzed comparison.

Objectives : The purpose of this study was to examine the results of the 2013 students' mental health school-community cooperative model. This study investigated teachers' awareness of change in school environment and analyzed the follow-up conditions of students. Methods : The sample consisted of 55 schools which participated in the 2013 students' mental health school-community cooperative model. Two questionnaires were used : one was composed of items about mental health resources, school policy and practice, school climate and community referral, and the other was on management of follow-up conditions for high risk students. Results : First, teachers' awareness regarding school mental health resources, school policy and practice, school climate, and community referral showed positive change. That is, the 2013 students' mental health school-community cooperative model works for improving teachers' interest, awareness and effort regarding mental health. Second, students, who were found by screening test and observation, were managed continually. Most students received follow-up interventions at school, and half of the students were referred to a specialized institution such as a mental health clinic, Wee center, personal counseling center, community welfare center, and so on. Conclusion : This study was a preliminary research, therefore follow-up studies are required in order to accomplish the 2013 students' mental health school-community cooperative model.
