The building construction projects include a variety of risk factors due to uncertainties. To succeed in the projects, it is important how risks are managed. Risk management processes identification, analysis and response. Especially, the analysis process is important to objectively identify importance and priority among risk factors. The purpose of this study is to develop the effective analysis process by studying and supplement the problem of the AHP analysis method. The study provides a analysis process to use the PROMETHEE analysis method proposed.

Object-oriented development has been generalized, but object-oriented project planning and scheduling techniques have not been studied enough. Furthermore, it is difficult to apply the conventional software management techniques to object-oriented projects. Especially, the large scaled projects are increasing, but the project planing techniques for these large scaled projects have not been proposed enough. In this paper, we propose systematic techniques for OO based project scheduling. We suggest a 7 step-process for deriving the OO project schedule from the use-case diagram which is describing the functional requirements of the system. The proposed process includes identifying use-cases, drawing preliminary chart through interdependency analysis, identifying characteristics of each use case, determining the number of iteration, assigning use-cases to iteration, considering available resource and constraints, drawing revised PERT chart. Each step has the explanation of the input, output, and the guidelines needed to perform the step. The project scheduling technique proposed in this paper ran be used effectively in the planning phase which the purpose is to plan a development schedule to yield the high quality software in minimum time.

From $1960^{th}$ Korean construction industry has been rapidly grown due to Meddle-East construction market growth. To earn foreign currency and to raise overall Korean industry government has encouraged construction frontiers. As construction industry could grow up for its labour based originity but the time passes by and overseas construction market requests engineering know-how and technology for productivity to earn more profit. Over last 20 years overseas construction market share has been dramatically raised but its profit share is gradually declining. This study analyzed data sets of over 180 overseas construction projects for last 30 years of domestic contractor by using multiple-regression analysis and derived an output how input variables of characters explaining the construction project effects its profit.

Project evaluation is the process of evaluating the progress and results of a project. Smart city projects can be divided into system components (infrastructure, services, platforms), or projects can run simultaneously for multiple services. In addition, services are developed and expanded through additional projects. In order to ensure that the smart city, which is composed of various projects, proceeds in accordance with the goals and strategies, periodic project evaluation is required during the project implementation process. The smart city project evaluation system proposed in this paper is designed to provide comprehensive and objective indicators by reflecting various factors that must be considered for projects occurring in all stages of planning, design, construction, and operation of smart cities. The indicators derived from the evaluation system can be used by decision makers to determine the direction of smart city project development. In addition, it is designed so that the performance of the project can be evaluated interim before the end of the project and the feedback obtained from it can be reflected. To introduce the application method of the smart city project evaluation system proposed in this study, the evaluation system developed in this study was applied to the smart city project case of Incheon Free Economic Zone (IFEZ). Based on the evaluation results, items that can maximize the improvement effect of each smart city project item were presented, and the direction of smart city project implementation was suggested. By utilizing a smart city project evaluation system that reflects the characteristics of smart city projects that are composed of multiple projects, comprehensive planning and management of smart city projects will be possible, and this study will serve as a reference for identifying priority improvement factors for projects.

This research studied the effect of visual improvement of "72 Hour Project" that has regenerated small scale derelict spaces in Seoul through citizen participation. 29 projects built form 2016 to 2019 were analyzed. The research analyzed landscape image preference of before and after status of projects using 12 pairs of landscape adjectives. Basic statistical analysis, correlation analysis, factor analysis, cluster analysis, and ANOVA were performed based on the survey results. Since the satisfaction level of the projects compared with the before-condition was 3.63 higher than 3.00, it could be concluded that there was an meaningful effect of visual improvement after completion of the projects. As the result of the factor analysis, landscape adjective pairs were categorized into two factors: harmony and aesthetics. Through the cluster analysis, four clusters were formed and characteristics of each cluster were identified. As the result of rhe cluster analysis, the cluster with the high harmony level and the aesthetics level showed the highest overall satisfaction level. Comparing each cluster, it could be concluded that the factor of harmony was more important than the factor of aesthetics in evaluating the satisfaction level of projects. Analyzing qualitative aspects of project groups, spatially well-balanced design with generous vegetation areas was more effective in landscape improvement than artistic design with visually strong installations. Further researches based on behavior studies of actual users are required to compensate the limits of this research. This research can contribute to establish the improved direction of policies to regenerate various types of small scale derelict spaces.

For a holistic and precise assessment of safety benchmarks within a construction venture, it's paramount to delineate between the intrinsic features of the construction and its real-time, on-site performance metrics. In this study, we delved into genuine accident instances to discern the interplay between these construction attributes and on-ground performance determinants in relation to safety mishaps, employing the binomial logit analytical framework. Our scrutiny underscored that construction expenditure profoundly modulates the likelihood of fatal occurrences. Notably, variables pertinent to on-site safety protocols wielded considerable influence over both fatal mishaps and accidents implicating multiple personnel. These revelations intimate that while ascertaining the safety quotient of a construction initiative, a mere classification and recalibration based on fiscal dimensions can elucidate much. Yet, a comprehensive safety appraisal necessitates transcending quantitative indices, such as frequency of mishaps or casualty rates, to encapsulate the multifaceted interventions and strategies adopted at the construction locale.

This study investigated the carbon offset project activities as the activities of producing commodities by a case study on the Korean Clean Development Mechanism(CDM) industry. This study draw the networks of Korean CDM industry by extracting major agents and surrounding agents and by analyzing the characteristics of the linkages. The project participants owning the CDM projects hires CDM consultancies and designated operational entities(DOEs). The technical knowledge for carbon emission reduction made links between project participants and the CDM project operational knowledge made links between project participants and CDM consultancies. Links between project participants and DOEs are affected by social and geographical proximities. The value of the knowledge for CDM industrial activities determined the role of agents and type of linkages. The agents with the irreplaceable knowledge could be a project conducting firms. The agents without it became outsourcing contractors.

대학에서 게임 개발 교육을 수행할 때 체계적인 방법론을 적용하는 것이 필요하나, 대부분의 방법론이 복잡하고, 또 사전에 방법론에 대한 교육을 시키기도 어려워 학교 교육에서 적용하기 어렵다는 문제가 있다. 여러 방법론 중 대표적인 애자일 방법론인 스크럼은 단기간의 개발을 지원할 수 있고, 상대적으로 쉬운 구조를 가지고 있어 학기 기반의 프로젝트 교육에 적합한 특성을 가지고 있다. 본 논문에서는 기존의 스크럼 방법론을 한 학기의 게임 개발 프로젝트 교육에 적합하도록 최적화한 CK-Scrum 방법론을 실제로 적용한 사례를 분석하고, 문제점을 보완하여 새로 개선된 CK-Scrum 1.1 방법론을 제시한다. 이 방법론으로 학생들이 프로젝트를 수행하며 품질이 높은 게임을 개발하고 방법론에 대한 학습도 병행할 수 있다.
