프로젝트관리 지식이 SI 프로젝트 성과에 미치는 영향 분석
지선희,손권일,김승철 한국프로젝트경영학회 2012 한국프로젝트경영연구 Vol.2 No.2
현대의 기업 경영에서 정보시스템은 일상적인 업무의 진행뿐만 아니라 장기적인 성장 잠재력과 경쟁력의 확보를 위해 매우 중요한 역할을 차지하고 있다. 이런 점에서 각 기업들은 효율적이고 통합된 정보시스템 구축을 위해 많은 노력을 기울이고 있으며, 시스템 통합(SI) 프로젝트가 많이 추진되고 있고 그 중요성도 계속 증가되고 있다. 시스템 통합 작업과 같은 일들은 주로 프로젝트의 형태로 진행이 되며, 프로젝트를 성공적으로 수행하기 위해서는 일반적으로 지식과 경험이 필요한 것으로 여겨지고 있다. 따라서 프로젝트의 성과는 각 기업과 조직이 축적한 지식과 경험, 즉 프로젝트 수행능력에 의해 영향을 받는다고 가정할 수 있다. 기업의 프로젝트의 수행능력은 여러 가지로 평가될 수 있으나 일반적으로 기업이 축적한 프로젝트 관리와 관련된 다양한 지식수준을 측정하는 프로젝트관리성숙도 모형을 이용해 평가하는 방법이 널리 사용된다. 본 논문은 기업의 프로젝트관리 지식수준과 프로젝트 성과와의 관계를 파악하기 위하여 시스템 통합(SI) 프로젝트를 대상으로 하여 연구하였다. 프로젝트관리성숙도 모형의 개념을 적용하여 기업의 프로젝트 지식수준과 능력을 평가하였으며 측정도구로는 설문지가 사용되었다. 시스템 통합 프로젝트를 수행해 본 경험이 있는 프로젝트 참여자들을 대상으로 데이터를 수집하여 통계적인 분석을 실시하였다. 연구의 결과에서 프로젝트관리 지식영역 중에 통합관리, 범위관리, 일정관리, 의사소통관리, 리스크관리 분야가 프로젝트 성과에 영향을 미치는 중요한 요소로 파악되었으며, 기업의 프로젝트관리 지식수준과 프로젝트관리성숙도는 밀접한 상관관계를 가지는 것으로 나타났다.

Purpose: Peritoneal lavage cytology is part of the routine staging workup for patients with advanced gastric cancer. However, no qualityassurance study has been conducted to show variations or biases in peritoneal lavage cytology results. The aim of this study was to demonstrate a test execution variation in peritoneal lavage cytology between investigating surgeons.Materials and Methods: A prospective cohort study was designed for determination of the positive rate of peritoneal lavage cytology usinga liquid-based preparation method in patients with potentially curable advanced gastric cancer (cT2~4/N0~2/M0). One hundred thirty patients were enrolled and underwent laparotomy, peritoneal lavage cytology, and standard gastrectomy, which were performed by 3 investigating surgeons. Data were analyzed using the chi-square test and a logistic regression model.Results: The overall positive peritoneal cytology rate was 10.0%. Subgroup positive rates were 5.3% in pT1 cancer, 2.0% in pT2/3 cancer, 11.1% in pT4a cancer, and 71.4% in pT4b cancer. In univariate analysis, positive peritoneal cytology showed significant correlationwith pT stage, lymphatic invasion, vascular invasion, ascites, and the investigating surgeon. We found the positive rate to be 2.1% for surgeon A, 10.2% for surgeon B, and 20.6% for surgeon C (P=0.024). Multivariate analysis identified pT stage, ascites, and the investigating surgeon to be significant risk factors for positive peritoneal cytology.Conclusions: The peritoneal lavage cytology results were significantly affected by the investigating surgeon, providing strong evidence of test execution variation that could be related to poor diagnostic accuracy and stage migration in patients with advanced gastric cancer.

교육과정을 기반으로 한 초등학교 에너지 교육 사례 연구
이성희,박지희,신경민,지선희 에너지기후변화교육학회 2012 에너지기후변화교육 Vol.2 No.2
The purpose of this study is to investigate energy education being implemented in Korea elementary schools and to discuss its implications. In addition, this study aims to provide practical cases and various implications for elementary school teachers to use in their energy education. Energy education is closely related to elementary curriculums as well as students' everyday life. The result of the study suggested that, Since there is no energy-related textbook separately the elementary curriculum develop various ways and methods to guide how to integrate separate curriculums and how to use it to prepare energy-related activities based on the currently used curriculum in elementary school.

Is Microsatellite Instability Really a Good Prognostic Factor of Colorectal Cancer?
신의섭,조상식,문선미,박선후,지선희,Eun-Joo Jung,황대용 대한대장항문학회 2014 Annals of Coloproctolgy Vol.30 No.1
Purpose: The aim of this study was to investigate the clinicopathologic features of and the prognosis for colorectal cancers (CRCs) with microsatellite instabilities (MSIs). Methods: Between 2006 and 2009, genotyping was performed on 245 patients with stage II/III CRCs to establish the MSI status. The clinicopathologic differences and the prognostic value of MSI were analyzed. The median follow-up period was 38 months (range, 7–68 months). Results: Of the total 245 patients, 20 (8.2%) had MSI-high (H) and 225 (91.8%) had MSI-low (L) or stable (S) CRCs. Adjuvant chemotherapies were performed on 101 stage II (87.8%) and 107 stage III patients (82.3%). Patients with MSI-H CRCs more frequently had a family history of colon cancer (10% vs. 2.7%, P = 0.003), more frequently had a cancer located at the proximal colon (90.0% vs. 19.1%, P < 0.0001), and more often showed a mucinous phenotype or poor differentiation (35.0% vs. 7.1%, P = 0.001). Despite less frequent lymph node metastasis (25% vs. 55.6%, P = 0.01), the number of retrieved lymph nodes was higher (26.3 ± 13.1 vs. 20.7 ± 1.2, P = 0.04) in the MSI-H group. The overall survival and the disease-free survival (DFS) did not differ with respect to MSI status. However, in the stage II subgroup, the DFS for patients with MSI-H CRCs was significantly worse (72.2% vs. 90.7%, P = 0.03). The multivariate analysis performed on this subgroup revealed that MSI-H was an independent poor prognostic factor (adjusted hazard ratio, 4.0; 95% confidence interval, 1.0–15.6, P = 0.046). Conclusion: MSI-H CRCs had distinct clinicopathologic features, and MSI-H was an independent poor prognostic factor in stage II CRCs. Considering the majority of stage II patients were administrated adjuvant chemotherapy, the efficacy of adjuvant chemotherapy for treating MSI CRCs might be different from that for treating MSI-L/S tumors.
