Human walking is essential and important mean of transportation. Pedestrian safety is recently important because accidents often happen while walking. This research is showing that Walking-environmental factors have effect on safety while walking. At first, exact 15 factors and conduct survey in the preceding research. After that, exact 4 important factors through factor analysis. At result of Multiple regression analysis, null hypothesis has proved to be true by satisfying therms which is F-value 9.211 and P-value 0.000. and come to the conclusion that walking-environmental factors influence pedestrian safety. 4 important factors can be listed by below. Pedestrian-road characteristic, landscape characteristic, commercial characteristic, walking characteristics by following influence. Especially, landscape characteristic and pedestrian-road characteristic can be vital factors.

The purpose of this study is to find the effect of home environmental stimuli and mothers' personal variables in multicultural family on children's linguistic abilities. The object of this study is 132 infants and their mothers of 82 infant education institutes located in P city. The main results of the study are as follows: First, the means of communication (generally Korean) is found to have the greatest effect 0n children's linguistic abilities of the personal variables of mothers from multicultural families. Second, the formation of stable and predictable environments affects children's linguistic abilities (receptive and expressive language) most of all the home environmental stimuli. Third, children's receptive language was most affected by the formation of stable and predictable environments, and their expressive language was most affected by the aspects of physical environments.

The aim of this study to assess the effect of information security policy awareness, information security involvement, compliance behavioral intention on information security behavior The research method is composed of a cross-sectional design of reward and fairness. This paper focuses on the process of organizational policy on the information security compliance intention in the individual decision-making process. As a result, the reward had a significant effect on compliance behavioral intention, and it was found that influence of the psychological reward-based condition was greater than the material reward-based condition. The fairness had a significant effect on information security policy awareness, information security involvement, information security behavior, and it was found that influence of the equity-based condition was greater than the equality-based condition. The exploration model was verified as a multiple mediation model. In addition, the discussion presented the necessary research direction from the perspective of synergy by the cultural environment of individuals and organizations.

The amount of energy consumed by a transportation system in a city is influenced not just by a transportation system itself but also by city's spatial character. Yet there have been very limited studies on this subject. This study investigates the factors that influence the energy consumption by a transportation system and city's spatial character. The model of an urban area confined within a definite boundary is assumed in order to develop the relationships between the energy consumption and the transportation system. Various assumptions on the character of a city and activities are made. An equation for computation of the energy consumption is derived with such factors as modal split, densities of residents and workers, as well as technological development. Using the equation, sensitivity analyses are performed in order to identify the relationships between energy consumption and influencing factors. It is found that the modal split is the most powerful factor that determines the energy consumption by the transportation system. Yet it is also found that the densities of residents and workers and the technological factors are very important in determining the amount of energy consumption as well.

IPTV has been drawing attention as a representative convergence media. The analysis of the convergence media, as like IPTV, requires an investigation into the use perception and multidimensional factors. So this research examines the IPTV usage, based on the Technology Acceptance Model. The analysis was made with the 500 users, based on the online survey. The first results is concerned with the user characteristics. A positive influential relationship between the user characteristics and use perception was confirmed, along with the individual attribute and environmental influence. The second, 'perceived ease of use' was found to positively influence 'perceived usefulness' and 'perceived playfulness'. This finding suggests that it is an important diffusion strategy to enhance the ease of use of IPTV. The third is the emphasis of playfulness of IPTV. Since IPTV is multimedia, playfulness played a significant role in diffusing IPTV. The application of the TAM to the media analysis of IPTV, which reflects the environments of the convergence media and use perception, was successful in drawing a significant outcome.

This study explores how social media influences individual's social development and well-being. Social media is discussed as an effective tool when individuals lacking social and psychological resources are trying to expand their social networks. This study focuses on the social media use of North Korean defectors, who, in general, have closed social media networks in the South Korean society. This study tries to analyze empirically the effect of social media use on North Korean defectors' satisfaction with our society. In particular, this study focuses on how the use of social media influences satisfaction with their life in South Korea at different levels of their emotional states. This study explores that the relationship between social media and satisfaction with their life in South Korea varies based upon the degree of self-esteem and anxiety. This study expects that social media might provide greater benefits for those who are experiencing low self-esteem and high anxiety. In addition, this study conducts the same analysis for the general public and then compares its results with the survey on North Korean defectors. According to the results of North Korean defectors' survey, the impact of social media use on satisfaction with their life in South Korea was greater for those with high anxiety than for those with low anxiety. Meanwhile, the impact was greater for those with high self-esteem than for those with low self-esteem.

정보 네트워크는 데이터 뿐 아니라 사물들의 연결성을 부추기고 있으며, 이에 따라 소프트웨어의 현실에 대한 영향력은 더욱 커지고 있다. 한편 로봇의 몸체(하드웨어)와 두뇌(소프트웨어)를 분리하고 네트워크를 통해 연결하는 연구개발시도가 늘어나고 있으며 이는 저가형의 경제성 있는 로봇을 개발하는 원동력이 되고 있기도 하다. 따라서 소프트웨어를 중심으로 한 로봇의 필요성, 역할 비중, 가능성은 그 어느 때 보다 크다. 이 글에서는 소프트웨어 로봇의 기능을 자동으로 확장할 수 있는 체계 구축의 가능성을 따져보고 이를 가능하게 하는 기반 기술로서 웹서비스와 시맨틱웹 기술 동향을 소개한다. 이들은 열린 웹 공간에서 서비스와 지식을 공유할 수 있는 표준 프로토콜과 지식 표현 체계를 제공한다. 이들 기술과 열린 네트워크 환경을 기반으로 스스로 지식과 서비스 수단을 습득하여 능력을 확장할 수 있는 소프트웨어 로봇을 구현할 수 있으리라 기대한다.

프로젝트에서 리스크 관리란 프로젝트 진행 시 발생가능성이 있고, 프로젝트에 긍정적 또는 부정적 영향력을 가진 이슈를 미리 발굴하여, 효과적으로 관리하기 위한 기법이다. 이런 점에서 리스크 관리는 프로젝트 목적 달성 즉 성공을 위한 수단이며, 예기치 못한 사건에 대한 사후대책 보다는 사전대책의 특성을 가지고 있다. 이러한 리스크 관리에 대하여 건설, 금융, 국방, 공공 분야의 프로젝트에서는 그 중요성을 인식하여 다양한 분야의 연구가 활발히 진행 중이고 현장에서도 활용하고 있으나, 소프트웨어 개발 프로젝트에서는 아직 그 중요성에 대한 인식이 부족하고, 현장에서의 활용도 저조하다. 반면 소프트웨어 개발 프로젝트에 대한 고객의 요구사항(비용절감, 일정 단축, 품질 향상, 신기술 적용등)은 점점 복잡해지고, 정교해지고 있어 제한된 리소스로 개발을 진행해야 하는 프로젝트 팀 입장에서는 프로젝트 성공에 대한 부담감이 점점 증가하고 있다. 본 연구에서는 리스크 관리를 수행한 프로젝트와 그렇지 않은 프로젝트의 사례를 비교하여 리스크 관리가 프로젝트 성공에 미치는 영향에 대해 연구하였다.
