The production process of construction industry is different from thing of the general manufacturing, likewise various participants make temporary teamwork for success of the project through sharing of information. But, the each role of participants is Individually changed to step in construction process stage and moreover it has complicated, entangled interests. The CM(so it called Construction Management as an abbreviation word) system was inducted for the effective management and operation of construction project. The key of the CM success depends on the cooperative relationship relation to major participants. There are lots of studies and efforts for the performance measures of the CM, however existing performance index is only measured as the viewpoint of project owner. Therefore it needs to make up for balanced view through combination of the four-way view of participants. In this study, we should search for cooperative relationship of project participants, and then we should suggest to define the difference of project in their viewpoints.

The construction industry has remained stagnant for a long time. So many researchers have wanted to solve this problem not only focusing on enhancement of construction process, but also introducing the culture of cooperation. The Last Planner System(LPS), one of the elementary techniques of Lean Construction, aims for improving the work reliability and reducing variability by measuring and managing the daily or weekly performance for overcoming the weakness of recent complex schedule management tools such as Critical Path Method. This research propose a framework for implementation of LPS conducted by owner focused on construction stage and introduce optimal owner participation model in plant construction, based on needs analysis for construction participants. Furthermore, this research introduce a modified needs analysis, so called IPBA(Importance-Performance-Betterment Analysis), and an advanced LPS procedure which add the needs analysis during pre-LPS and(or) main LPS stages.

The participants of steel works should exchange a variety of information with others through documents. However construction steel works in the multistage contract system has a difficulty in exchanging information through the documents promptly. So if the trouble as change orders arise, conducting steel works will take much time, and the participants may not discuss the trouble sufficiently. Consequently this study improved the current business process of steel works. And this developed business support system(XCOS) based on XML so that participants of steel works achieve a successful management of steel works through conducting business rapidly and correctly.

The scientist-led Research and Education (R&E) program aims to strengthen gifted science students' research capabilities under the guidance of scientists. Students' actual research experiences in scientist-led R&E activities range from understanding how scientists conduct research to actively participating in research. To develop R&E that promotes student agency, i.e., student participation, this study aimed to identify the pedagogical characteristics that supported gifted science students' agentic participation in the scientist-led R&E program. We conducted interviews with learners and scientists in three teams undertaking R&E activities every three months. The interview covered their perceptions of R&E activities, student participation, and scientists' support for the activities. The recordings and transcripts of the interviews were used as primary data sources for the analysis. The trajectory of each team's activities, as well as the learners' and scientists' dynamic positioning were identified. Based on this analysis, we inductively identified the pedagogical characteristics that emerged from classes in which the scientists supported the students' learning and engagement in research. Regarding agency, three types of student participation were identified: 1) the sustained exercise of agency, 2) the initial exercise and subsequent discouragement of agency, and 3) the continuous non-exercise of agency. Two pedagogical characteristics that supported the learners' agentic participation were identified: 1) opportunities for students to take part in research management and 2) scientist-student interactions encouraging learners to present expert-level ideas. This study contributes to developing pedagogies that foster gifted science students' agentic participation in scientist-led R&E activities.

Libraries are one of the essential living infrastructures in urban regeneration. Beyond its meaning as a basic living infrastructure, it is necessary to first understand the role, nature and forms of participation in existing urban regeneration projects in order for libraries to perform their functions and roles effectively as participants of urban regeneration. Therefore, this study investigates the contents related to libraries in the contents of the strategic plan related to urban regeneration projects, and considers them in terms of the role of the library and the form of participation. Through this, the city's library would seek to maximize its role and function as a participant in urban regeneration. As a result, the library in urban regeneration is expected to improve the quality of living environment, Urban vitality, culturally, educationally, socially/welfare role closely related to life, and the role of community as a hub. In addition, the types of library participation could be largely divided into regional and geographical libraries, hybrid libraries combined with various services, libraries based on community cooperation and linkage, and regional community hub libraries based on community participation. In the future, the library needs to promote a more active role change based on the five roles expected as participants in urban regeneration. In addition, more detailed discussions on librarians, services, and programs, which are the main subjects of library services, will be needed in developing urban regeneration plans in order for libraries to successfully fulfill their role as urban regeneration centers.
