중견/중소 IT기업의 사업 수행 기회 증대, 기회 균등과 역량 강화라는 취지로 소프트웨어(SW)산업진흥법 개정으로 공공정보화시장에 대기업 참여를 제한되었다. 이러한 환경에서의 중견/중소 SW기업들의 사업을 수행하면서 발생한 사업 수행 역량 미흡으로 공공정보화사업의 품질저하, 위험관리 미숙, 일정관리 저하 등 여러 문제점을 발생시키고 있다. 이를 해결하기 위해 본 논문은 시스템통합 사업 수행 시 품질 저하 요인을 도출하였으며, 이를 해결하기 위한 방안으로 VISUALIZATION, 엄격한 시험관리, Agile방법론의 일부 활동을 적용하여 프로젝트를 수행하는 것을 제안했다. 이러한 방안을 중견/중소 IT기업이 개발한 보건의료 IT 프로젝트에 적용한 결과 의사소통의 개선, 수치화된 진척관리 및 프로젝트의 가시성이 개선되었다. 또한, 결함 해결시간 최소화, 요구사항 커리리지 비율 개선, 불필요한 회의시간이 단축이 되어 품질 향상에 기여하였습니다.

As population concentration, high-rise, and high-density progresses amid rapid industrialization and urbanization in Korea, green areas in the city have decreased significantly and the natural environment has deteriorated day by day due to various development projects. In order to cope with these social changes, many studies related to park and green areas have been conducted, but in the case of Gwangju-si, only studies on green areas such as vegetation structures, street facilities, and recreation forests have been conducted on park green areas. The situation is not losing. Therefore, in this study, a survey was conducted on Gwangju citizens to understand the usage behavior and satisfaction of park green areas, and to provide basic data for future park development and reorganization. As a result, first, to induce a variety of static and dynamic activities in order to increase the park satisfaction of Gwangju citizens, it is possible to create a park that has not been formed as soon as possible, and by planning programs with various themes. Second, it is necessary to expand green space services in marginalized areas by creating water streams, flower pots, and rooftop greening around the lives of Gwangju citizens, and create park green spaces with themes using cultural and historical resources for each administrative district. Third, in order to solve the dry landscape in some urban areas, it is necessary to establish a three-dimensional landscape plan by creating a variety of green areas such as potted plants, green areas, and street trees, and by giving functions of park green areas such as expanding leisure and convenience facilities.

대규모 병원정보시스템 프로젝트가 계획 대비 지연되는 경우가 종종 발생하고 있다. 따라서 프로젝트 관리 측면에서 일정 지연을 촉발하는 원인을 검토하고 지연 유발 요인들 간 인과관계 분석이 필요하다. 본 연구는 근거이론 방법론을 활용하여 병원정보시스템 개발 프로젝트 사례에 대한 일정 지연 요인을 발견하고 이들 간의 인과관계를 파악하고자 한다. 연구 결과, '비현실적 일정 수립'은 도미노 현상과 같이 전반적인 일정 지연에 영향을 미치고, '기존 시스템 분석 미흡'은 분석 품질의 저하를 야기하는 반면 '서브시스템 통합 인터페이스 부실'은 설계 품질의 저하로 이어졌다. 본 연구는 학술적인 측면에서 프로젝트 지연에 영향을 미치는 요인을 찾아내고 지연 요인들 간의 인과 관계를 분석하였으며, 실무적 관점에서는 System Integration (SI) 기업, 병원, 프로젝트 관리자 입장에서 프로젝트 일정 지연을 최소화할 수 있는 방안을 제시한 점에 의의가 있다.

Background: The purpose of this study is to investigate the factors affecting the healthy living practice rate such as non-smoking, moderate drinking, walking, and low-salt diet by elementary municipality (so called, 'si-gun-hu'). Methods: The 2016 Korean Community Health Survey was used for the analysis. The theoretical model is founded upon the Anderson model, and both the multiple linear regression analysis and the beta regression analysis was performed for estimation. Results: As a result of the beta regression analysis, healthy living practice rate was found to be significantly higher in the areas with a less number of cigarette retailers, participating in healthy city projects, a low proportion of people who perceive their body type as obesity, a higher proportion of women, and a lower proportion of spouses. Conclusion: In order to improve healthy living practices, the regulations on health risk businesses, the spread of Healthy City project, and policy efforts awaring obesity are recommended.

Compared to research on the success of IT projects In general, research on the management of conflict in IT teams and its impact on project success is insufficient. This research performed a comparative study to analyze the nature and evolving phenomenon of conflicts in IT project teams. This study aimed at; First, Why a conflict is created within and around an IT project team. Second, What is the phenomenon of conflict evolution, diffusion, and/or resolution? Third, How the differences in conflict management style affects the IT project performance? Three propositions were drawn from the analysis of two intensive analysis of conflict cases and their comparison. Proposition 1 : Both 'the method of pointing out a problem' and 'the pointed-out contents' can be the trigger of conflicts around an IT project. Proposition 2 : While the focus of attention of one party is 'the method of pointing out a problem', if the other's and focus of attention of one party is 'the pointed-out contents', that is, if the focus of attention mismatch, the conflict can be amplified. Proposition 3 : According to the temporal nature of the relationship, e.g., short-term versus long-term, the way people approach and deal with the conflict differs.

Jeju, the biggest island in Korea, was registered as a World Natural Heritage in 2007. Recently, it was also voted as one of the New Seven Wonders of Nature. The need for academic awareness and tourist values on Jeju Island are understood. Gal-ot, one of the ten symbols for Jeju, is known for working clothes in general, despite its potential for cultural products because of its regional uniqueness and useful functional advantages. The authors conducted a comprehensive literature review and researched market trends of Gal-ot stores in Jeju to present development directions for cultural goods and to contribute to local economic improvement. Most stores were located in a semi-residential area and Jeju-si in Jeju Special Self-Governing Province. Most products were not available for sale due to difficulties in the production process and online utilization. High prices and similar color, fabric and style hurt competitiveness. Various experiencing programs of Gal-ot and persimmon dyeing were necessary to expand the main target from residents to tourists. Also, marketing strategies using the internet and design plans reflecting current trends were needed. This study would contribute to prepare developmental projects of cultural product and result in economical advantages on Jeju Island.

As the cloud-based ICT(Information & Communication Technology) infrastructure matures, the existing monolithic software development method is evolving into a micro-service structure based on cloud native computing. To develop and operate the services efficiently under the cloud native environment, DevOps-based application development plans through MSA(Micro Service Architecture) design based are essential. A cloud native environment is an approach to developing and running applications that take advantage of cloud computing models such as automation of source distribution, container-based virtualization, application scalability, resource efficiency, and flexible maintenance through object independence. To implement this approach, the utilization of key elements such as DevOps, continuous delivery, micro service, and containers is essential, but there are not enough previous studies on case analyses or application methods of these key elements. Therefore, in this paper, we analyze the cases of application development in cloud native environment and propose the optimized application development process and development method through small and medium-sized SI projects.

Nowadays in Republic of Korea, whole amount of the thermite welding powder for rail joinning is dependent on import. However the demand of the thermite welding powder would be enlarge because some constructing high-speed train and city metro projects are currently in progress. In addition this is the main reason why we should develop the thermite welding powder, domestically. This study is focused on utilizing the recyclable materials like Al powders from cans and iron oxide scales from wire rods as the main components of the thermite welding powder. By minimizing Al content in weld zone by controlling the mixing ratio of the Al powder in the thermite welding powder, the excessive dissolution of the Si and Mn components came from the Al powders could be controled. The tensile strength of welding zone in welded rail was 740 MPa, with that the developed thermite welding powder.
