eXtreme Programming(이하 XP)은 프로젝트를 수행하는 데에 있어서 흔하게 발생하는 위험 요인들을 Light-weight 한 방법으로 해결하기 위한 방법론이다. XP 개발 방법론은 개발 주기의 단위를 작게 나누어서 피드백을 받는 기간을 짧게 잡았다는 점과, Pair Programming 방법을 도입했다는 점, 개발 과정에서의 고객의 비중을 높이고, 다양한 모듈 테스트/기능 테스트를 통해서 제품의 오류를 최소화 했다는 점 등의 특징을 갖고 있다. 그러나 XP는 소규모의 개발팀일 경우에만 그 효용성이 입증되고 있으며, 수많은 테스트 과정과 개발의 전과정에서의 고객의 적극적인 참여의 요구는 생산 비용면에서나 고객의 부담에 있어서 단점으로 여겨지고 있다. 따라서 본 고에서는 이러한 점들을 보완하기 위한 몇 가지 방안과 더불어 우리나라의 개발 환경에 효과적으로 적용하기 위한 방안을 제시하고자 한다.

운영 체제 수준 가상화 기술의 결과물인 컨테이너는 경량화된 가상화 환경의 특징과 도커 프로젝트를 통한 손쉬운 패키지 관리와 배포를 특징으로 급격히 성장하였다. 이로써 컨테이너를 기반으로 한 IoT 클라우드 구성에 관한 연구가 진행되고 있지만, 한정된 자원과 성능을 가진 IoT 장치에서는 컨테이너의 가용성을 보장하기가 어렵다. 따라서 본 논문에서는 컨테이너의 서비스가 종료되고 다시 개시되기까지의 시간이 어떤 요인에 의하여 영향을 받는지 분석한다.

This paper looks into how to enhance construction project management, focusing on the change order, which is often considered one of the major causes for construction delays, disputes, and claims in the middle east construction. First, this paper categorizes the major causes of change orders. It suggests a detailed classification standard for affecting factors resulting from change orders based on a case study result of an on-going construction project in the Middle East. In particular, this paper presents a method to apply a machine learning-based feature selection to quantify the importance of change order triggers and affecting factors. As a result, the case study identifies six major change order triggers and eight affecting factors. Also, a meaningful relationship between change order triggers and affecting factors by each category is presented. This paper will contribute to setting a clear guideline for change order management for the international plant construction field while helping prevent construction delays and cost run-ups by reducing the time required for change order resolution between project owners and contractors.

With the development of IT technologies, IT environment is making great change over life whole and is displacing business and business achievement systems of industry at the fast speed. The system which is proposed in this paper, supports environments to share codes, execution files and objects between project teams to maximize productivity and efficiency in web environments. Through impact assessment which is achieved at correction and development of existing programming codes by maintenance requirements, it minimizes obstacle occurrence factors and supports tracing obstacle sources. Through conversion the correction and development histories of existing sources and executable files between project teams to XML documents suitable to share in web, it stores them to relational database. In this paper, through impact assessment and change management for the correction and development of applications in the existing system development environments, we support efficient IT developments.

This study examined the factors influencing safety scores in air conditioning installation projects, with a specific focus on the characteristics of safety managers and project-specific details. Given the increase in industrial accidents within this sector and the lack of research on smaller-scale operations, this analysis of 7,046 safety data records from Company A aimed to address this gap. The results indicate that the month of project commencement has the most significant impact on safety scores(correlation coefficient of 0.21), followed by the age of the safety manager(correlation coefficient of 0.06). Interestingly, the educational background of the managers did not appear to influence safety outcomes. Furthermore, project cost was found to have a negative correlation with safety scores(-0.1), suggesting that lower-cost projects may be associated with higher risk levels. These findings underscore the importance of developing tailored safety checklists that take into account the specific timing and scale of air conditioning installation projects. Additionally, the results suggest that incorporating both experienced(older) and less experienced(younger) safety managers into safety strategies may be beneficial for achieving optimal safety outcomes. This balanced approach could leverage the strengths of both groups, potentially enhancing overall risk assessment and mitigation efforts.

Universities have been investing in their information systems to keep their management functions working efficiently and effectively. Thanks to these efforts, faculty members and other university employees can perform their tasks efficiently almost anywhere and anytime. Several universities embarked upon information systems projects to take advantage of emerging information technologies in their administration and management. Only a limited number of universities have achieved their objectives; some others have been even tinkering with the idea of abandoning their newly developed academic information systems. The development of academic information systems often start with a relatively high risk of system failure. Sometimes, these systems encounter unforeseen obstacles or fail in systems development. These universities with problems also can overcome these issues by collecting their wisdom. The mindfulness theory is suitable for dealing with implementing academic information systems. This research analyzes an academic information systems development case from a mindfulness perspective, and also addresses its research implications and theoretical contributions.

This paper limited the participation of large corporations in the mass information market by revising the Software Industry Promotion Act in order to increase business opportunity, equality of opportunity, and capacity building for small and medium sized IT companies. However, it is a fact that the medium and small SW companies have insufficient business capacity and expose various problems such as quality degradation of public information business, inadequate risk management, and deterioration of schedule management. In order to solve this problem, this paper derived the factors of quality deterioration in the system integration project and proposed to carry out the project by using some activities of VISUALIZATION, rigorous test management and Agile Methodology as a solution. Applying these measures to healthcare IT projects developed by midsize / small-sized IT companies has improved communications, improved quantitative progress management and improved project visibility. In addition, it contributed to minimizing defect resolution time, improving the requirement coverage ratio, and shortening unnecessary meeting time.

Climate changes caused by fossil fuel energy usages have led to serious environmental damages and resource scarcity. Ever-increasing demand for energy causes harsh competition in international energy markets. Nuclear power, which once was regarded as a desirable clean energy, began to face public oppositions after the Japanese nuclear disaster in 2011. In this context, wind power is now considered to be an ever-more important recyclable energy source. Thus, this study intended to identify critical success factors for wind power construction projects. After a thorough literature review, two focus group interview sessions were conducted. A questionnaire-based survey, coupled with the two previous methods, resulted in the extraction of important factors for the success of wind power projects. Experts, including those working as constructors, designers, and owners, were paid a direct visit for the interview and survey. The critical success factors were categorized into feasibility study, right policies, equipment selection, and project financing issues. The proposed critical success factors are expected to be an effective guideline for future investors in wind powers.

The purpose of this study is to review a good sample for a healthy city to adapt its strategy. People has interested in the urban environment and their health in the region with a step-up in income and the improvement of living conditions. They has realized that urban environment is closely related to their quality of life, concentrated on development of clean city and healthy city from the point of urban planning. The movement of healthy city has been spread out from Europe on 1986, and WHO(World Health Organization) has been supporting the practical work to improve upon the physical or social condition on each regional level. The policy of healthy city has promoted centering around each local government which is made up of networking with others globally to interchange informations. This study reviewed a successful case of Kobe city in detail and will provide further useful insights into planners in building appropriate policies.
