The aim of this study is to propose economical safety driving speed index which those are geometric road status; examine the levels of which those cost-benefit of driving fuel expenditure; are search road safety design and operational technology for driving simulators. For the objective, we analyzed the current status of driving fuel expenditure and driving scenarios by the road alignments, and reviewed driving and technical specifications by the geometric types of road according to the implementation, and extended completion. Throughout the result of this study, diverse related driving information provision service, efficiently driving system is expected to be implemented in the national highway design system.

The objectives of this study is to: (1) develop how applications for driving simulator of national highway safety designs when those are appeared; (2) examine the degree to which those geometric designs of the horizontal and vertical profile; and (3) search positive safety and passive highway safety design of the point at which highway alignment factors initiate driving safety to facility or highway design.

The objectives of this study is to achieved by the use of the conceptual approach and accident data bases to develop statistical accident analysis, effectiveness values, comparison analysis of statistical models to determine which variables are significantly related to accidents, human factor, and hazard factor analysis, all of which were used in the railroad crossing. The result from this approach applicable to the railroad crossing where systematic safety management criteria have been considered.

The objective of this study was to make comparison of the physical work capacities(PWCs) for three different types of tasks. For this purpose, an ergometer exercise, a treadmill exercise, and lifting activities with four different frequencies (2, 5, 8, 11 lifts/min) for the lifting range from floor to 76cm were considered. Oxygen consumption rates and heart rates were measured during the exercises and lifting activities. The PWC values for ergometer exercise test was $2562.71ml-O_2/min$ and the one for treadmill exercise was $2874.89ml-O_2/min$. The value of lifting PWC increased from $1774.07ml-O_2/min$ to $2296.76ml-O_2/min$ as the lifting frequency increased from 2 to 11 lifts/min. The ratio of the lifting PWCs to the ergometer PWC increased from 69.36% to 89.77% as the lifting frequency increased. To the treadmill PWC, the ratio increased from 62.21% to 85.24% as the lifting frequency increased. From this result, it appears that the PWCs based on the lifting tasks rather than PWCs by ergometer or treadmill exercise should be considered to determine the physiological criterion for safe weights for lifting tasks. Therefore, the physiological criteria of the NIOSH Guideline should be reexamined.

This study explored behaviors and problems of the secondary poor,using survey and policy analysis. As a result, the fact that the secondary poor among a lower income class significantly depend on mass media than any other group, was reaffirmed. They use traditional mass media,for example, TV, as an almost utmost medium in terms of source for information gathering, social interaction and education. They recognized television as a vital medium in providing various, reliable, everyday life and learning information. Also, factors such as information function affected more significantly to their satisfaction than those of criticism and surveillance to the secondary poor. However, they are generally dissatisfied with having to burden subscription fee to pay TV as well as KBS,indecent language use, and homogeneous entertainment programs which do not care them much. As for policy aspects, this study suggested more economic aids should be necessary to bridge the gap with others, especially considering their poor economic condition. Also, viewer-friendly remote control device,media education and public relation should be accompanied. Moreover, this study emphasized TV programs, which mesh with the taste of the secondary poor, are much more needed and they should be reflected as equal in mass media as well. 본 연구는 디지털 융합 환경에서 방송소외계층의 하나인 저소득층 중 차상위 계층이방송서비스를 어떻게 이용하고 있는지를 설문조사를 중심으로 분석함으로써 방송소외를 최소화할 수 있는 정책방안을 모색했다. 연구결과, 차상위계층은 방송미디어를 거의 유일한 정보획득 및 사회화와 교육 매체의 수단으로 이용하고 있음을 보여주고 있어 이들에게 TV매체의 영향력이 타 매체보다는 상대적으로 매우 크다는 점을 알 수 있었다. 또한 방송에 대한 전반적인 태도를 보면다양한 소식 전달, 믿을만한 정보 제공, 생활/학업 필요 정보 제공이 기타 항목보다 상대적으로 높았고, 방송에 대한 전반적인 태도가 만족도에 영향을 미치는 평가요인에 있어서도 사실적 정보전달 기능이 비판/고발 정보전달 기능과 믿을만한 정보전달 보다 중요한 영향을 미치는 것으로 나타났다. 차상위계층의 방송에 대한 불만족 요인으로 특히KBS 수신료와 유료방송 수신료 이중부담 문제에 대해 가장 심각하게 평가하고 있고,출연자의 비속어/외래어 사용 잦음, 프로그램 내용의 유사성에 대해 문제를 제기하고있었다. 차상위계층을 포함한 저소득층은 경제적인 어려움이 제일 크기 때문에 지원을 더욱늘려야 하고, 노인들과 저학력층 등에서 리모콘 조작과 프로그램 이해 등의 능력이 떨어지는 경우가 많으므로 방송 미디어 활용 교육과 홍보 등이 필요하며 노인층과 중장년층을 위한 프로그램의 편성 비중을 늘려야 한다. 또한 방송 프로그램 내용에서 소외 계층을 배려하고, 일반인들과 동등하게 묘사하고 인식시키고, 사회적 통합을 위해서 프로그램의 기획과 제작에서부터 고려해야 한다.
