The sum of each work duration are entire period in construction project. Each work occurs to be late, the total period of construction project will delays. Therefore, the total period of construction project will not be delayed if probability of working progress makes higher. Finding each work's constraints performs constraints analysis in process of construction for checking probability of working progress. Grasp work's constraints through the constraints analysis and removes. This research will show preventing delay of consruction project, through constraints analysis process.

This study analyzed the effect of workplace innovation on business performance and labor condition improvement. The study results showed that work process standardization and quality control positively affected business performance. Also, downsizing, reducing individual subcontract, expanding non-core business outsourcing positively affected both business performance and labor condition improvement. In addition, labor union's participation moderated the effect of work process innovation on business performance. This study provided implications for analyzing the effect of workplace innovation comprehensively and extending the scope of study to personal employee dimension.

In this paper, we analyse the marine leisure base condition of the archipelago at the southwest sea area which has the natural advantage for marine leisure. We also discuss how to adapt the yacht business on the above area. At first, we analyse the current situation of the domestic marine leisure and draw up a plan to solve its problem. Finally we apply an environment friendly marina establishment to the archipelago at the southwest sea area and evaluate its validity.

Military Power is the most direct and actual measures for national security. For construction, maintenance, management of military power, the adequate expenditure is required but it is difficult to increase blindly owing to the lack of resources. There are security threats and economic conditions in determining of military expenditure. Republic of Korea has been more influenced by economic conditions than by security threats since 1990s In this paper, we analysed relation between real military expenditure and real GDP through regression analysis.

Studies on the distribution of traffic demands have been proceeding by providing traffic information for reducing greenhouse gases and reinforcing the road's competitiveness in the transport section, however, since it is preferentially required the extensive studies on the driver's behavior changing routes and its influence factors, this study has been developed a discriminant model for changing routes considering driving conditions including traffic conditions of roads and driver's preferences for information media. It is divided into three groups depending on driving conditions in group classification with the CART analysis, which is statistically meaningful. And, elements of the driving conditions and the preferred media affecting the change of paths are classified into statistical meaningful groups through the CHAID analysis, and the major factors affecting the change of paths are examined. Finally, the extent that driving conditions and preferred media affect a route change is examined through a discriminant analysis, and it is developed a discriminant model equation to predict a route change. As a result of building the discriminant model equation, it is shown that driving conditions affect a route change much more, the entire discriminant hit ratio is derived as 64.2%, and this discriminant equation shows high discriminant ability more than a certain degree.

As the problem of lowering the efficiency of urban services in small and medium-sized cities in the non-metropolitan area intensifies, the necessity of developing a railway station area is being emphasized to form a compressed urban space through regional bases. Although major station areas in large cities are being developed in the form of complex, the analysis of the development location characteristics of the small and medium-sized city station areas is insufficient. The purpose of this study is to analyze the characteristics of development project conditions and potential demand in the high-speed rail station areas across the country, identify the differences in locational characteristics according to the type of city, such as 'metropolitan city', 'large city in non-metropolitan city', 'medium and small city in non-metropolitan city', and find out the appropriate development method. As a result of the analysis, it was analyzed that the 'metropolitan area metropolitan area' has high potential demand and poor business conditions. On the other hand, in the case of the non-metropolitan area, it was analyzed that the 'small and medium-sized city station area' has good business conditions and low potential demand characteristics, and the 'large city station area' has intermediate characteristics. This suggests the need for different development methods in the development of metropolitan and small and medium-sized city station areas. The analysis results of this study show that it is desirable to encourage private participation in large-scale metropolitan station areas, which require large-scale input, to maximize potential demand, and to encourage private participation through public-led projects based on favorable business conditions or development based on regional characteristics.

The purpose of this was to analyze the current situation of preschool education in the YanBian area, China, and put forward some policy implications for the field of education in the area. One class of children who were arranged by their teachers participated in this study. Quantitative data of the educational situation from 2011 to 2013 were collected and data analysis was conducted to analyze the current situation in the YanBian area. The results of data analysis indicated that there have been a variety of situational issues and problems in the preschool education of the YanBian area, and it needs improvement. On the other hand, improvement and development in the area has been going on. Still some areas have not developed yet. Some suggestions and implications will be suggested for the educational future in the YanBian area, China.

Construction industries is a labor intensive industries. According to Korea Productivity Center, most OECD members indicate high labor productivity more than Korea labor productivity in construction industries. First of all, for increasing labor productivity work efficiency and work condition should be managed by administrator in work site. Especially, work condition could be controlled by the management behaviors of administrator in work site such as work management type. This indicates that work management type could influence strongly work condition. But although that work management type could influence work condition is the characteristic of construction work is recongized to many people, the quantitative analysis on the relationship between work condition and work management type is not enough. Therefore the purpose of this study is to analyze the Influence of Work Management Type on Work Condition.

국내의 건축물의 화재안전성 평가는 화재안전성을 고려한 공간구성, 연기의 유동, 거주자의 피난계획 및 피난성능평가, 건축물 내부에 설치된 방화설비계통의 화재안전성능평가 등을 연구하여 왔다. 그런데 이들 연구의 대부분은 건축물의 공간적 특성분석과 주거여건 등을 고려한 기초자료의 파악 및 분석 등을 국내의 여건과는 상이한 국외의 자료를 근거로 하거나 2차원적인 해석 및 평가에 그치고 있는 경향이 있다. (중략)

The purpose of this paper is to analysis spatial locations for public sector's development of mixed-use complex. The results of analysis of location characteristics and public sector's participation conditions are as follows. The central commercial district of new town, surroundings of new railway station, and old town center are likely to be appropriate in the case of a functional mixed-use considering acceptable use in accord with mixed-use complex. Development potential is also high at places such as railway adjacent area in old town and relocation of downtown improper facilities including previous three cases. And development of various size such as lot, block and district can be applied at central commercial district of new town, center and subcenter of old town, surroundings of new railway station. The result of analysis of public sector's participation conditions is appropriate in central commercial district of new town by public sector, relocation of downtown improper facilities and old site of transferring public facilities. They can be contribute to grow up new town by public-private partnership and to improve urban circumstances and publicness by development old site coupled with new site of transferring public facilities.
