Companies are paying attention to project governance to realize their goal strategies, project success, and project value in a rapid and complex environment due to the development of information technology. This study aims to explore project governance and factors from literature review and practice guides related to project governance and empirically analyze the impact of project governance factors on IT project objective performance. The survey was conducted on project managers, project team members, and project management members with experience in carrying out business IT projects within two years at companies in various industries in Korea. The main conclusion is as follows. Among the project governance factors, disclosure and reporting that uses and reports using appropriate and reliable information about projects related to decision-making activities positively impact the achievement of IT project objectives: business success and stakeholder satisfaction. Among the project governance factors, project sponsorship, a role that effectively connects management and projects, and a project management framework that provides tools, procedures, resources, and techniques for projects positively impact IT project objective performance. This study is of academic and practical significance in that it identifies the definition and factors of project governance through companies in various industries in Korea and the positive impact of project governance factors on IT project objective performance.

The present study has shown that the effect of boron and phosphorus in Ni-Cr-Si-X alloy to interfacial reactions and bonding strength of diamond-steel substrate, and the influence of various construction parameters on the formation of the topography of the tool. And these factors are required to making a good brazed tool. The microstructures and phase change of the brazed region were analyzed into SEM, EDS. According to the electron probe microanalysis, while brazing, the chromium present in the brazing alloy segregated preferentially to the surface of the diamond to form a chromium rich reaction product, which was readily wetted by the alloy.

본 연구는 서울 도시 비오톱(n=54)을 대상으로 서 식지 면적 에 따른 조류 종수를 파악하고자 2001년 가을과 2002년 봄에 실시하였다. 도시 비오톱을 대상으로 조사한 조류종수의 연구에서 비오톱 면적의 크기가 조류종수에 뚜렷한 영향을 미치지 않는다고 생각되어진다. 전체 대상지에서 32종의 조류가 관찰되었으며 1㏊미만에서 는 13종, 1-10㏊에서 는 29종, 10㏊이상의 면적에서는 8종의 조류가 나타났다. 비오톱 면적 크기에 따른 조류종수의 증가에 관한 연구에서, 면적의 크기가1-10㏊인 대상지가 <1㏊ 이거나, > 10㏊인 대상지보다 더욱 많은 조류가 관찰되었다. 또한, 종-면적 축적 곡선에서 는 작은 면적의 서식지가 추가되어졌을때 종수의 증가율이 지속적으로 높아졌다. 이에 도시 지역에서 조류 종수의 증가를 위해 필요한 최소면적은 1-10㏊가 효과적일 것이라 생각된다. 또한, 수자원과 다양한 식생구조를 가진 비오톱에서 조류종의 뚜렷한 증가를 보였다. 따라서 이러한 환경의 조성은 작은 면적의 서식지도 조류종의 증가에 도움이 될 수 있을 것이다.
