Purpose: The purpose of this study is to identify the health promoting lifestyle and need assessment of a health promotion program. and to develop a health promotion program for rural elderly. Method: The subjects of the study were 366 adults chosen from 24 villages located in Geochang Gun, Korea. Data sampling used a quota sampling method. Analysis of the data was done by using descriptive statistics, t test, ANOVA and the Scheffe test with SPSS. Results: 1) The average score of performance in the health promoting lifestyle was 1.85. In the subscales, the highest degree of performance was 'nutrition', followed by 'interpersonal relationships', 'health responsibility', 'stress management', 'spiritual growth', and the lowest degree of performance was 'physical activity'. 2) Health promoting lifestyles were significantly correlated with such demographic variables as age (F=2.684, p=.047), education (F=10.989, p=.000), monthly pocket money (F=3.516, p=.008), religion (F=7.160, p=.000), current health status F=3.375, p=.035), health education (t=2.476, p=.014). 3) Health promoting lifestyles were significantly correlated with such life style pattern variables as milk drinking (F=3.767, p=0.035), hobbies (t=3.072, p=0.002), exercise (t=7.186, p=0.000). 4) There is a high level of need for the need assesment of the health promotion program for the elderly in the rural area. Conclusion: With the above findings. I propose that it is necessary to understand a health promoting lifestyle and need assessment for a health promotion program, and to develop a health promotion program considering regional and environmental elements.

공학인증을 시행한 지 적지 않은 시간이 흘렀음에도 인증에 가장 중요한 요소들 중의 하나인 학습성과의 평가에 대한 평가도구 개발은 대부분의 프로그램들이 가지는 어려움들 중의 하나이다. 본 연구에서는 이의 한 방편으로 교과목과 학습성과의 연관성에 근거하여 해당 교과목이 어떤 학습성과를 성취할 수 있는지의 여부를 정한 후, 한 학기동안 해당 교과목을 수강한 학생들이 치룬 시험과 제출한 보고서를 근거로 하여 학습성과를 정량적으로 평가하는 방법을 보여준다. 또한 학기말에 해당 교과목 담당교수가 작성하여야 할 CQI보고서의 작성 예를 통하여 이에 대한 즉각적이고 효과적인 학습성과의 방법에 관하여 고찰하였다.

Housing is demanded to convert simple dwelling space into delightful one by improving of standard of living by economic development It is interested in the impact noise of the apartment housing that is revised to housing construction criteria at 29 March 2005 and then regulated the level of floor impact noise by the rule. The plan, which is actively investigated by counterplan for the reduction of impact noise, is application of sound insulation. In generally, first target by using insulation is the reduction of floor thermal transmittance in floor heating system of apartment housing. It is recently proposed soft materials that reduce the impact noise. However, it is a fact that the application of soft sound insulation includes some problem about structural performance. In this study, we made wet-heating specimen with various sound insulations, and carried out structralexperiment for evaluating the structural safety of it.

Computerization of educational administration following educational informatization of government has been steadily improved for the purpose of teachers' offload and job efficiency, finally resulting that NEIS(National Education Information System) has been completed. The NEIS consists of Nationwide service of NEIS, Business portal system of NEIS, Authentication management system and so on. Students, parents and civil petitioners handle civil affairs through Nationwide service of NEIS and teachers and persons of task conduct theirs business by accessing the Business portal system of NEIS. At this time, users have to obtain their certification from Authentication management system. Previous Studies were mainly focused on the evaluation about its performance according to the introduction of NEIS. But from now on there is a growing interest in security assessment and an efficient method for security improvement to check if NEIS works properly. Therefore, in this thesis, we'll propose an analytic framework in which security assessment is carried out after comprehending the fault structures through performing Fault Fishbone Analysis based on the Fault Tree Analysis. As a result of the system applied, the system had the highest rate of improvement to 47.7 percent.

Fog may have a significant impact on road conditions. In an attempt to improve fog predictability in Jeju, we conducted machine learning with various data mining techniques such as tree models, conditional inference tree, random forest, multinomial logistic regression, neural network and support vector machine. To validate machine learning models, the results from the simulation was compared with the fog data observed over Jeju(184 ASOS site) and Gosan(185 ASOS site). Predictive rates proposed by six data mining methods are all above 92% at two regions. Additionally, we validated the performance of machine learning models with WRF (weather research and forecasting) model meteorological outputs. We found that it is still not good enough for operational fog forecast. According to the model assesment by metrics from confusion matrix, it can be seen that the fog prediction using neural network is the most effective method.

본 연구에서는 콘크리트 구조물인 교량의 교각과 같은 압축부재의 충격하중을 정량적인 손상지수로 평가하기 위해서 동적유한요소해석 프로그램인 LS-DYNA를 이용하여 차량의 충격각도에 따른 충격도, 세장비 등을 변화시켜 case별 해석을 수행하였다. 본 연구결과를 통해 콘크리트 구조물의 거동해석 및 설계기법을 Bayesian 통계방법을 이용하여 충격하중을 받을 시의 성능기반형 설계기법을 산정하였으며, 이는 실제 충격하중에 의한 구조물의 방호성능 및 설계 시에 적절하게 적용할 수 있을 것으로 판단된다.

성능위주소방설계 초기단계로서 피난안전성평가에 있어서 Available safe egress time (ASET)과 Required safe egress time (RSET)를 계산하여 단순비교하고 있다. 본 논문에서는 FDS를 이용하여 열, 연기, 독성가스 등에 대한 위험정보값을 추출하였다. 또한 피난시뮬레이션 프로그램인 Artisoc를 이용하여 FDS에서 추출한 위험정보값을 적용하였다. 건축물의 구조는 가로 60 m, 세로 65 m로 구성하였으며, 출입구는 2곳에 설치하였으며 재실자는 50명을 랜덤하게 배치하였다. 시뮬레이션은 case1~case20 까지 총 20회에 걸쳐 진행하여, 피난 경로별 위치에 따른 재실자의 위험도를 분석하였다. 이를 통해 위험정보값을 적용하여 기존의 단순비교 하던 피난안전성평가의 신뢰도를 높이기 위한 위험정보값 전달기반의 평가기법을 제시하였다.

본 논문에서는 단순화 다자유도 모델링 방법을 이용하여 유연한 지붕을 갖는 l/2 축소 단층 보강조적조 건물의 지진 거동을 분석하였다. 선형 및 비선형 해석에 의한 결과들은 l/2 축소모형 단층 건물의 진동대 실험결과와 비교ㆍ분석되었다. 정확한 면내 및 면외 강성과 강도를 산정할 적절한 방법이 없기 때문에 구조모델 보정방법을 적용하여 반복적인 비교 ·분석 과정에서 각 부재의 강성과 강도변화에 따른 민감도를 평가하였다. 보정된 구조물의 특성을 사용하여 구조 재해석을 수행하였으며, 지붕구조물의 유연성이 전체 건물의 동적 거동에 미치는 영향을 분석하였다. 유연한 지붕은 전단벽의 면외 강성과 강도에 많은 영향을 미치게 되며, 강체 지붕과는 확연히 구분되는 동적 거동을 보여주었다.

Surely fuel economy(F.E.) label is needed to meet consumer's right to know. Korea has developed and adopted F.E. correction equation similar to the feeling, because consumer complain about F.E. label higher than they feel. Recently, through continuous research and development high-efficiency & performance green car like HEV, PHEV and EV are being sold. In this situation, it is needed to know whether the current equation can reflect a part of their improved technic or not. In this paper, to review current equation through test using hybrid vehicles on 5-cycle SOC, correction equation and F.E were discussed. The result show HEV didn't meet the SOC error standard on US06. Also, HEV has bigger F.E. difference between FTP-75 and 5-cycle than conventional vehicles. However, the correction equation that include HEV almost same with current one.
