산림 사업이 산림의 탄소저장량에 미치는 영향을 알아보기 위하여 임상도, 산림사업 정보 및 토양 정보 등을 활용하여 산림 사업 전후의 지상부 및 토양의 탄소저장량을 산정하고 그 변화를 분석하고자 하였다. 먼저 임상도 정보에 기초하여 면적이 넓고 영급이 감소하는 도엽 6곳을 선정하였다. 그리고 임상도와 생장계수, 산정 지역의 토양유기물함량, 토양용적밀도 등 데이터를 수집하여 산림 탄소저장량을 산정하였다. 그 결과 모든 곳에서 산림 탄소저장량은 산림사업 후 약 34.1~70.0%가 감소하였다. 그리고 기존 연구와 비교했을 때 국내 산림 토양은 지상부에 비해 더 적은 탄소를 저장하고 있어 우리나라의 산림 토양은 더 많은 탄소를 저장할 수 있는 잠재성이 큰 것으로 판단되며 탄소저장량 증대를 위한 전략이 필요할 것으로 판단되었다. 산림사업이 없을 때 있을 때보다 탄소저장량은 약 1.5배 많은 것으로 추정되었다. 그리고 본 연구에서 산림사업에 따라 간벌 전 산림 탄소저장량으로 회복되기까지 약 27년이 걸리는 것으로 추정되었다. 산림은 물리적 훼손에 의해 탄소저장량이 감소하면 원래의 탄소저장량으로 회복되기까지 오랜 시간이 걸리므로 특히 자연성이 높은 산림은 최대한 보전하는 계획을 수립하여 산림의 탄소저장 기능을 유지할 수 있도록 하여야 할 것이다.

In order to improve the sustainability and smart construction, it is discussed arguably that developing and applying consistent "standard model" to plan business, design, construct and operate a building is considered to be one of the effective and efficient approach. The scope of this article is to examine, from the international developer's perspective, the "standard model" approach of a hotel brand to building projects in the UK, and also to explore potential role of project team to mitigate any local difference at the project level. These projects are developed by the same developer adopting the same business plan, design and operation to each project. In order to clarify the actual and likely difference in construction results, reference is also made to those building projects located in other geographical markets including Japan, Germany and USA, and focus is given on the analysis of its programme and cost. Principle findings are that there exists geographical difference especially in environmental and planning system, and that major local difference is found at least in the programme at the design stage. In contrast, the difference in the building cost itself may not be necessarily considered major if currency exchange rate being taken into account appropriately. It is also observed that there were cases where any difference in the programme was mitigated by taking different approach to procuring and defining roles of management and professional team at the project level. In conclusion, from the international developer's perspective, the geographical difference of the "construction system" surrounding building projects can typically lead to major prolongation of programme, however, these different construction results could be mitigated at least to a certain extent by introducing appropriate changes to the role of project team.

Effective communication flow is a fundamental for the success of any construction projects. The key role of communications among project parties is even more critical in the case of Design-Build (DB) projects. Previous research has shown that these projects have an environment where integration between different project team members and schedule constraints increase channels of communication, and require faster communication flows. This paper summarizes the findings from research analyzing organizational structures and communication flow of the Texas State Highway 130 (SH130) project. Awarded in 2002, the SH130 project, totaling $1.3 billion USD, constitutes the "pilot" application for the DB approach in the state of Texas. A set of observations pertaining to team organization and communication issues in the design-build environment is included.

Mega-Y project is very important for a company to gain a competitive advantage in markets or to achieve drastic change in the internal processes. It stems from the company strategy and annual management goals or key performance measures, and is proceeded by the cross-functional team. This paper presents the success factors and implementation process of the Mega-Y projects. The implementation process is presented in 5 steps, including project selection, cross-functional team building, establishment of the master plan, development and execution of sub-projects, and project completion. A case study on the cost reduction project of aircraft development is presented to help for the practitioners to deploy the implementation process introduced in this paper.

최근 팀 구성원들은 팀 프로젝트 수행 시 모바일 메신저 서비스(MMS: Mobile Messenger Service)를 자주 활용한다. 팀 구성원들은 MMS 활용을 통해 언제 어디서나 자유롭게 아이디어나 의사를 표현할 수 있다. 하지만, 팀 프로젝트에서 MMS 활용은 오프라인 회의보다 빨리 프로젝트를 수행하도록 압박을 받고, 능력 범위 밖의 역할을 할당 받기도 한다. 즉, 팀 구성원들은 MMS 활용으로 인해 업무에 대한 압박감이나 스트레스가 증가할 수 있으며, 이러한 과부하는 팀 간 갈등을 야기할 수 있다. 본 연구에서는 MMS 활용으로 인한 업무 과부하가 팀 성과에 미치는 영향을 살펴보고자 한다. 팀 성과에 영향을 미치는 요인으로 팀 몰입과 팀 신뢰를 고려하였으며, 팀 갈등은 팀 몰입과 팀 신뢰를 저해한다고 예상하였다. 팀 프로젝트가 많은 135명의 대학생을 바탕으로 연구 모형을 분석하였으며, PLS를 활용하였다. 연구 분석 결과 업무 과부하는 팀 갈등을 야기하는 주요 요인으로 밝혀졌다. 즉 MMS 활용으로 인한 업무 과부하가 발생하다보면 팀 간 갈등이 야기될 수 있고, 이는 팀 구성원 간 신뢰를 저하시켜 결국 팀 성과가 떨어지는 결과를 초래하게 된다. 마지막으로 본 연구 논문에서는 팀 프로젝트를 향상시킬 수 있는 MMS의 올바른 사용 방법에 대한 시사점을 제공해주었다.

Recently, knowledge transfer has been recognized as one of the major factors for success of IT projects but little investigated in Information Systems research. IT project, which needs collaboration between organization's IT project team and external partner, is an critical source for a firm to acquire external knowledge and to achieve its competitive advantage. Based on this recognition on knowledge transfer under IT project, we investigate a mediation role of knowledge transfer to IT project performance after identifying its antecedents such as project team capabilities and partner capabilities. The research model is tested by analyzing 161 sample data gathered from firms' employees who have participated IT projects within last two years. The results reveal that knowledge transfer has full-mediation effect between its antecedents and IT project performance. Moreover, project team capabilities have more impacts on knowledge transfer than partner capabilities do.

The purpose of this study was to investigate the cognitive mechanism of e-Learning contents development projects on the basis of the Shared Mental Model theory perspective. To pursue the purpose, a theoretical model and several hypotheses were developed based on relevant literature. Thirty five (35) e-Learning contents development teams composed of 202 instructional designers from for-profit professional e-Learning companies in Korea were participated in this study. For the analyses of the fit of the Model and parameter estimations, Structural Equation Modeling (SEM) method was employed. As hypothesized, e-Learning contents development team members' interaction leads to higher SMMs which in turn facilitate member satisfaction within the team. Meanwhile, the frequency of interaction among team members decreases as projects progress.
