Safety-related accidents are continuously increasing in the construction field. In order to prevent or minimize such accidents, a systematic and active safety activities of on-site managers and workers are required. However, preexisting advance research is lacking on how the safety organization systems are built in construction sites varying in sizes, and how well-trained the related personnel are in safety knowledge and task performances. Especially, a research on the analysis of the formation of their safety knowledge sharing and safety performance cooperation and their visualization is virtually nonexistent. In this regard, this research was conducted with a purpose to study the generalized safety organization method of domestic construction sites, analyze the safety knowledge and cooperation system of the members based on the SNA method and ultimately provide a hands-on data that could be effectively utilized in building an effective safety management system in the future.

In this paper, we suggested the integration between automatic enforcement system and UTIS(Urban Traffic Information System) base station. UTIS base station and automatic enforcement system are different in the height of installation and the type of communication network. UTIS base station is 25 meter high and communicate with center system by optical network. Whereas automatic enforcement system is 6.6 meter high and communicate with center system by rental network. For the purpose of suggesting the efficient method of integration, research was as in the following. We found that the number of integrated system was 1,628 through the present state of analysis and UTIS equipment was satisfied with the required specifications through field testing. Also we suggested the appropriate configuration of the integrated system and analyzed that the cost of the integrated system installment is 1/5 lower than that of the legacy system installment.

This study aims to examine the mediating effect of parental monitoring and child's self-esteem on the relationship between parental time and child's life satisfaction in single mother families. For this purpose, MOGEF (Ministry of Gender Equality and Family)'s 'Research data of adolescents in 2015' was used and 117 single mothers and their children aged 9 to 18 were selected for the analysis. Structural Equation model analysis reveals that adolescent's self-esteem has a mediating effect on the relationship between parental time and adolescent's life satisfaction, though parental time and parental monitoring have no significant effect on adolescent's life satisfaction. With these results, policy suggestions to support single mothers' parental time were proposed.

Seoul's One Less Nuclear Power Plant is the major urban energy policy launched in April 2012. Its effort to respond to climate change and energy crisis in the aftermath of the Fukushima nuclear accident turned out very successful, considering huge decrease of energy consumption. However, the question of how the cut of energy consumption was possible remains unanswered. This paper introduces the concept of urban governance capacity as the cause of the success. It is the managing and governing capability to maintain the logical consistency policy system, comprising of policy perception, goals, policy tools and evaluation. Without this logical correspondence between the policy factors, any system including energy regime easily falls apart during the systemic transitional period. Governance capacity provides the integrating framework, so that the system as a whole maintains the internal homeostasis.

This is the first study of the relation between the controversy on Korean Economics and the controversy on the capitalist social formation of Korea in the 1970-80. The main results of this study is as following: Almost all Korean Economists think 'Korean Economics' do not exist, but korean philosophers think Korean philosophy which is different from western philosophy do exist. So Korean economists tend to believe in the universal validity of western economics. In fact, Some Korean Economists began to argued about universal validity of American-Western economics and making Korean Economics in 1970s, the controversy ceased in the mid of 1980s. Left-wing Economists insisted that the right wing conservetive economics is imported from, mainly, U.S.A, Korea is academic colony of U.S.A. But progressive economics was also imported from Western world, or Soviet Union in the process of controvesy on Korean capitalist social formation in 1980s. It is necessary to retrospect and re-examine the controversy on Korean Economics and on Korean capitalist social formation to develop Economics of Korea.

In the US, there are no governing bodies within the federal executive departments dedicated to the arts and cultural affairs. Direct government subsidies for the arts are relatively small compared to other countries with a comparable economy and standard of living. Nevertheless, the US produces artworks, artists, and arts groups, leading the world's arts and culture. Incorporating the concepts of network governance and shared governance, this paper examines the dynamic roles and interrelationships among various for-profit/nonprofit arts organizations, foundations, councils, service organizations, arts advocacy groups, and professional/amateur associations from the federal to local levels that compose the ecology of American arts and culture. Through our evaluation, we conclude that the local/state/federal arts agencies and arts organizations at various levels influence each other via the principle of subsidiarity and isomorphism, creating a unique cultural policy and arts-supporting system that correspond to the political and social structure and environment of the United States.

This study amis to analyze the levels of citizen inclusiveness in Korea by the 17 local government levels. Citizen inclusiveness was measured by donations, volunteering, and citizen perception indicators. This study adopted the ideal type method of fuzzyset analysis. We found that citizen inclusiveness was classified into 6 types: inclusive citizen type, inclusive citizen-oriented type, donation-oriented type, volunteering-oriented type, citizen perception-oriented type, and individual-oriented type. This study analyzed key features of these 6 ideal types of citizen inclusiveness. More research on citizen inclusiveness is needed. Trends of changes in citizen inclusiveness and key factors on citizen inclusiveness will be examples of future studies. Inclusive welfare states need both government's efforts in enhancing welfare institutions and citizens' advancement in inclusive citizenship. This study concludes with several implications for further developed citizenship for inclusiveness.

Recently, scanning projects have been carried out in various construction and construction fields for maintenance purposes. The point cloud generated by the scan results is composed of a number of points representing the object to be scanned. The process of extracting the necessary information, including dimensions, from such scan data is called paradox. The reverse engineering process of modeling a point cloud as BIM involves considerable manual work. Owing to the time-consuming reverse engineering nature of the work, the costs increase exponentially when rework requests are made, such as design changes. Reverse engineering automation technology can help improve these problems. On the other hand, the reverse design product is variable depending on the use, and the kind and detail level of the product may be different. This paper proposes the G2BM (Geometry-to-BIM mapping) rule definition method that automatically maps a BIM object from a primitive geometry to a BIM object. G2BM proposes a process definition and a customization method for reverse engineering BIM objects that consider the use case variability.
