Nowadays, the IS project is getting more and more complicated and large-scaled. Many researchers and practitioners are interested in the IS development methodologies, automated tools and techniques to decrease project failure and to increase IS project performance. This research is to seize the management level of PMO affecting on the IS project, as a new method to increase the IS project development performance. As a result of surveying the present PMO operation state with banks which are the leading industry to accept the PMO in Korea, technology support management and infrastructure management are the core functions to affect the IS performance including schedule management, quality management, and user and stakeholders' satisfaction. Also, the PMO management level is the important point of IS project success. Among the 5 levels PMI suggested, PMO can implement the project effectively at least at the third level. Korean companies introducing the PMO have to do research the PMO core functions and the management levels according to the project scale, and review the distinctive features of their organization to increase the maturity of IS project. This research has been proved through the Full Structural Equation Model. The results show that the five core functions of PMO have relationship with the IS project performance.

$H_5PMo_{10}V_2O_{40}$ ($PMo_{10}V_2$) catalyst chemically immobilized on sulfur-containing mesoporous carbon (S-MC) was prepared, and it was applied to the benzyl alcohol oxidation reaction. S-MC was synthesized by a templating method using SBA-15 and p-toluenesulfonic acid as a templating agent and a carbon precursor, respectively. S-MC was then modified to have a positive charge, and thus, to provide sites for the immobilization of $PMo_{10}V_2$. By taking advantage of the overall negative charge of $[PMo_{10}V_2O4_{40}]^{5-}$, $PMo_{10}V_2$ catalyst was immobilized on the S-MC support as a charge matching component. It was revealed that $PMo_{10}V_2$ species were finely and molecularly dispersed on the S-MC via chemical immobilization. In the vapor-phase oxidation of benzyl alcohol, $PMo_{10}V_2$/S-MC catalyst showed higher conversion of benzyl alcohol and higher yield for benzaldehyde and benzoic acid than unsupported $PMo_{10}V_2$ catalyst. The enhanced catalytic performance of $PMo_{10}V_2$/S-MC was due to fine dispersion of $PMo_{10}V_2$ species on the S-MC via chemical immobilization.

A periodic mesoporous organosilica material was synthesized by microwave heating (PMO-M) using 1,2-bis(trimethoxysilyl)ethane as a precursor in a cationic surfactant solution, and textural properties were compared with those of the product produced by conventional convection heating (PMO-C). These synthesized materials were characterized using XRD, TEM/SEM, N2 adsorption isotherm, 29Si and 13C NMR, and TGA, which confirmed their good structural orders and clear arrangements of uniform 3D-channels. Synthesis time was reduced from 21 h in PMO-C to 2-4 h in PMO-M. PMO-M was made of spherical particles of 1.5-2.2 m m size, whereas PMO-C was made of decaoctahedron-shaped particles of ca. 8.0 m m size. Effect of synthesis temperature, time, and heating mode on the PMO particle morphology was examined. The particle size of PMO-M could be controlled by changing the heating rate by adjusting microwave power level. PMO-M demonstrated improved separation of selected organic compounds compared to PMO-C in a reversed phase HPLC experiment. Ti-grafted PMO-M also resulted in higher conversion in liquid phase cyclohexene epoxidation than by Ti-PMO-C.

After the revision of the Software Promotion Act, small and medium-sized enterprises (SMEs) with little experience in e-government projects began to participate in public projects. Accordingly, the government introduced the public Project Management Office (PMO) in July 2013 to reduce the risks and secure the quality of informatization business, and the public PMO is still spreading. However, the public PMO service currently experiences sluggish business, such as low-priced orders, due to cut-throat competition, and thus needs improvement plans. In this research, we establish a research model for quality factors of public PMO services that can be considered for the improvement plans, measure and evaluate quality factors based on the model, and then analyze the impact of service quality on customer satisfaction and customer loyalty. For that, we measure quality factors using the SERVPERF model for those who have used public PMO services, establish a structural equation research model, and empirically analyze and evaluate the impact of quality factors. Lastly, we suggest improvement plans and implications for public PMO services.

Recently, Information System (IS) development projects such as the next generation IS project of the financial business domain have shown tendency to become large and complex. Accordingly, a large number of enterprises have introduced a Project Management Office (PMO) to successfully manage multiple complex large-scaled projects. Many researches and empirical studies have proved the positive results of PMO-based projects. For example, most PMO-based projects have been accomplished successfully without exceeding the planned deadline and budget. However, even in the case of PMO-based projects, participants are still supported by legacy Project Management Systems (PMS) developed without considering the PMO. It implies that recent large projects are hardly performed efficiently because of the large gap between the legacy PMS tools developed only for single small projects and the real process of PMO-based project management. Therefore, we attempt to design and develop a PMO-based PMS in which the role and responsibility of PMO are completely implemented. To demonstrate our systems practicality, we applied the devised system to the real project management cases of "K" bank in The Republic of Korea. According to the results of case analysis, all of the four projects supported by our PMO-based PMS have been completed without exceeding planned deadline and budget, and the quality of their final outcome is appraised to be superior.

Nowadays, IS projects are getting more complicated and large-scaled. Therefore, many researchers and practitioners have been interested in the IS development methodologies, automated tools, techniques, and TQM to improve IS performance. Latest Standish Group's research reported that after the PMO introduction, project scale became bulkier than 1 or 2 year ago, and that IS development project success probability was increased sharply by 62 percents from 37. The previous researches listed just various PMO functions. This research is to seize the core functions and management level of the PMO affecting on the IS project performance with banks which are the leading industry to accept the PMO in Korea. The activities in the categories of implementation management technology support management infrastructure management are the core functions of the PMO to affect the IS performance including schedule management quality management user and stakeholders' satisfaction. Also, the PMO management level is important for IS project success. Among the 5 levels PMI suggested, PMO can implement the project effectively at least at the third level. Korean companies which are about to introduce the PMO have to consider the PMO core functions and management level to increase the IS maturity.

본 연구의 목적은 PMO의 기능들이 프로젝트 성과에 미치는 직접 효과와 프로젝트 관리 프로세스의 수행을 통한 간접 효과를 PLS 경로모형을 통해 파악하는데 있다. 또한, PMO 역량 및 최고 경영진의 지원에 따른 프로젝트 성과의 차이의 상호 효과 및 그 효과의 크기를 찾고자 한다. 본 연구에서는 방법론 제공, 행정적 지원, 교육 및 훈련, 자원 관리, 지식 관리를 통하여 형성되는 PMO기능과 통합, 범위, 시간, 비용, 품질, HR, 커뮤니케이션, 위험, 자원조달 등을 통하여 형성되는 프로젝트 관리과정을 측정하기 위하여 2차 요인 모형(second-order construct model)으로 연구 모형을 검증하였다. 본 연구에서 각 1차 요인(first-order construct)은 반영지표를 이용하여 분석 하였으며, 2차 요인은 조형지표를 이용하여 분석하였기에, 반영지표와 조형지표가 모두 포함되어있는 모형 분석에 용이한 자료처리 도구인 PLS를 이용하였다. 본 연구의 설문대상은 PMO의 지원 하에서 프로젝트를 수행해 본 경험이 있는 프로젝트관리자나 프로젝트 리더와 같은 전문가 집단으로 한정하여 온라인 설문조사를 실시하였다. 분석 결과, PMO 기능 및 프로젝트 관리과정 모두 프로젝트 성과에 유의한 영향을 미치는 것으로 확인되었다. 또한 PMO기능을 수행할 때, PMO역량에 따라 프로젝트 성과에 유의한 차이가 존재함이 확인되었다. 따라서 경영진들은 프로젝트 수행 시 프로젝트 성과에 긍정적 영향을 미치는 PMO의 설립을 적극적으로 검토해야 한다. 또한 PMO의 역량에 따라 프로젝트 성과에 차이가 발생하므로 프로젝트를 관리하는 PMO에 충분한 권한을 부여하고 경영진의 지원을 신속하게 함으로써 프로젝트를 성공적으로 수행할 수 있을 것이다.

Recently, the number and scale of projects being carried out within the enterprise are increasing. Accordingly, many companies are competitively introducing a Project Management Office (PMO) to efficiently manage these projects, allocate resources, and effectively link the projects and corporate strategies. However, the project manager who directly manages the project wants to receive support from the PMO in many areas for successful project management, but the project manager does not like to be interfered with by the PMO. On the other hand, the PMO may not be able to satisfy all the requirements of each PM as PMO oversees the entire project with limited resources. In addition, since the PMO must monitor and control the project and support the project according to the priorities of each project, conflicts with each PM can be formed. Therefore, in this study, based on the case of a company, the difference between the perceptions of PMs and PMOs about the importance of the required roles of PMOs is to be examined. As a result of the study, it was confirmed that the core functions and sub-functions of PMO, which PMO members and PMs consider important, are different. It was identified that the PMs valued the PMO function that would be helpful for their successful project execution. On the other hand, PMO members revealed that they had a relatively high priority for the roles to monitor and control project performance for which they were directly responsible.
