PMO(Project Management Office)는 해당 영역의 프로젝트를 조정된 중앙 통제 방식으로 관리하기 위하여 필요한 다양한 책임을 배정받은 조직, 부서나 주체를 말하며, 프로젝트 관리 지원 기능을 제공하는 일부터 직접적인 프로젝트 관리에 이르기까지 다양한 책임을 지니고 있다. 본 논문에서는 PMO 제도 도입에 따른 성공적인 공공 정보화 사업 완수를 위해 우리나라 PMO 관련 현 법제도 현황을 선행 연구자들에 따른 PMO 기능 분석 종합 자료와 미국의 표준화된 프로젝트 관리 프로세스인 PMBOK(Project Management Body of Knowledge) 관리 지식 영역 프로세스를 적용해 우리나라 현 법제도의 적합성을 비교 분석하였다. 연구 결과로 공공 정보화 사업에서 PMO 제도를 도입함에 있어 우리나라 현 법제도가 공공 정보화 사업의 품질을 높이는데 보완되어야 할 영역들이 요구되었다. 향후 본 연구를 통해 공공 정보화 사업의 PMO 제도 도입 시 법적 제도화와 전문성을 제고하여 성공적인 사업 수행에 도움이 되도록 하고자 한다.

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.

여러 산업 분야에서 신기술 도입 및 고객의 요구 사항 변화에 따라 급속한 정보화가 진행 중이다. 정보 시스템을 주요 기반으로 한 금융산업의 경우, 이러한 변화에 대응하기 위해 상당한 규모의 차세대 프로젝트를 진행하고. 이를 통해 기업은 법률, 규제 및 고객 요구 사항 등 외부 요인에 신속히 대응하고, 내부 프로세스 개선을 통해 기업의 가치를 성장시키려고 한다. 차세대 프로젝트란 기업이 반드시 성공시켜야 하는 프로젝트로, 금융권은 프로젝트 성공률을 높이기 위해 PMO 제도를 도입하고 있는 추세이다. 본 연구는 프로젝트 준비단계 산출물인 제안요청서 (RFP)를 국제 프로젝트 관리 표준인 ISO 21500 (Guidance on Project Management)을 기준으로 제안요청서 (RFP)가 프로젝트 성공에 필요한 제반 기능과 정보를 포함하고 있는지 분석하였다. 분석 결과 차세대 금융 PMO의 RFP는 ISO21500의 기준과 상당한 차이가 있음을 발견하였다. 향후 제안요청서(RFP) 작성의 중요성을 인식하고, ISO21500 관리 기준에 맞춰 기능을 개선하고 보완해 나간다면 프로젝트 성공률을 높일 수 있을 것이다.

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, TQM to decrease project failure, and to increase IS performance. But, in spite of such various efforts, the latest Standish Group's research indicates that the project scale is bulkier than $1{\sim}2$ year ago and IS development project's batting average falls from 34% to 28% at the same time, proceeded project is increased, and project discharged arrives to $15%{\sim}18%$. According to a research, success possibility increased by 37% after a year of PMO introduction, and increased sharply by 62% after 2 years and by 65% after S years. This research has a goal to survey how the PMO function and operation type affect the IS project performance in the financial industry. I determine nine independent variables and three dependent variables from previous researches. The results of this study are that the four core functions of PMO have relationship with project performance. But, technical support function does not relate with organization performance. Among the four core PMO operation types, three types have an effect on the IS project performance except the perfectionist type.

Mesoporous materials are a sort of promising materials with a wide spectrum of applications due to their unique well-defined porous structures that provide high surface area and controllable pore size. Among mesoporous materials, periodic mesoporous organosilicas (PMOs) are highly emerging materials in sense of applications due to their large pore sizes and organic functionality in the frame. The organic functional groups in the frameworks of these solids allow tuning of the surface properties and modification of the bulk properties of the material. This article provides a comprehensive overview of PMOs and discusses their different functionalities, morphology and applications, such as catalysis, environmental applications, and adsorption, for which PMOs have been used after their discovery. The review article will provide fundamental understanding of PMOs and their advanced applications to readers.

A hot water extract(HWE-P4) was separated from the fruit bodies of PMO-P4, and its antitumor and immunomodulatory activities against sarcoma-180 in ICR mice were investigated. The internal transcribed spacer(ITS) regions from PMO-P4 were amplified using polymerase chain reaction(PCR) and sequenced. The results revealed that PMO-P4 was belong to the Phellinus baumii. When oral administration at the dose of 160mg/kg/day in the mice until the end of the experiment with 2 week's pre-feeding of the HWE-P4, the survival rate of the mice was 152% for 50days after the inoculation of sarcoma-180 and the suppression rate of the tumor growth was 35.3%(p<0.05) for 28 days after inoculation of sarcoma-180. The HWE-P4 increased 71.4% of the CD4/CD8 ratio and 5-fold of the expression of CD25(IL-2 receptor chain) compared with the control. From these results, the antitumor activity of HWE-P4 is exerted through its immunomodulating activity on the host's immune system.

Under flooded rice fields, methanogens produce methane which comes out through rice stalks, thus rice fields are known as one of the anthropogenic sources of atmospheric methane. Studies have shown that use of manure increases amount of methane emission from rice. To investigate mechanisms by which manure boosts methane emission, comparative soil metagenomics between inorganically (NPK) and pig manure fertilized paddy soils (PIG) were conducted. Results from taxonomy analysis showed that more abundant methanogens, methanotrophs, methylotrophs, and acetogens were found in PIG than in NPK. In addition, BLAST results indicated more abundant carbohydrate mabolisetm functional genes in PIG. Among the methane metabolism related genes, PIG sample showed higher abundance of methyl-coenzyme M reductase (mcrB/mcrD/mcrG) and trimethylamine-corrinoid protein Co-methyltransferase (mttB) genes. In contrast, genes that down regulate methane emission, such as trimethylamine monooxygenase (tmm) and phosphoserine/homoserine phosphotransferase (thrH), were observed more in NPK sample. In addition, more methanotrophic genes (pmoB/amoB/mxaJ), were found more abundant in PIG sample. Identifying key genes related to methane emission and methane oxidation may provide fundamental information regarding to mechanisms by which use of manure boosts methane emission from rice. The study presented here characterized molecular variation in rice paddy, introduced by the use of pig manure.
