이 연구의 목적은 대학기록관의 특성에 맞는 기록물 전거레코드 구축을 위한 기술요소를 제안하되, 온라인 환경에서도 활용가능한 EAC-CPF와 융합한 기술요소를 제안하고 이를 근거로 전거레코드를 구축한 실례를 제시하는 것이다. 이를 위해 첫째, 대학의 기능에 따른 조직의 구성과 특성을 분석하고, 이를 토대로 기록물 생산자별 주요 특성들을 분석하였다. 둘째, 국내표준인 국가기록원 전거레코드 지침과 국제표준인 ISAAR(CPF) 2판을 비교·분석하여 대학기록물 전거레코드 구축을 위한 기술요소들을 제안하되, 이를 다시 EAC-CPF와 매핑하여 최종 기술요소를 도출하였다. 끝으로, 제안된 기술요소를 토대로 실제 전거레코드를 구축한 사례를 제시하였다. 본 연구 결과는 대학기록물 생산자의 맥락정보를 검색을 위한 표준화된 접근점을 제공하기 위한 구체적인 기술요소들을 제안하고 이를 데이터표준구조와 융합하여 온라인 환경에서도 생산자 맥락정보의 검색이 가능하게 했다는 점에서 연구의 의의가 있다.

건설 사업은 다양한 불확실성 및 리스크 요인으로 인하여 사업 수행 과정이 초기 계획대로 수행되고 있는지에 대한 반복적인 성과측정 및 후속 관리 조치가 필요하다. 이러한 성과 측정의 가장 대표적인 기준이 공정, 공사비, 품질이며 특히, 공정과 공사비의 경우 정량적인 평가가 가능하고 통합관리를 통해 효율성을 높일 수 있는 주요 관리 대상이 된다. 이를 위해 EVM(Earned Value Management)기법을 운영하도록 제도화 하였으며 EVM을 활용함으로써 사업 진도율 $15{\sim}30%$ 시점에서 사업의 EAC(Estimate at Completion)와 공정결과를 예측할 수 있다. 본 연구에서는 기존 EAC 추정의 문제점을 제시하고 회귀분석을 이용하여 적정 EAC 변동 범위를 예측한다. 따라서 공동주택 건설사업에서의 공사 수행 중 공정과 공사비의 문제점을 사전에 파악하여 변동 범위의 결과 값을 통해 의사결정자들이 효율적인 의사결정을 할 수 있도록 정보를 제공한 수 있을 것으로 판단된다.

This study was carried out to review and evaluate anti-CCP ELISA assay for diagnostic in RA patients from an early arthritis clinic (EAC). The subjects were obtained from patients visiting the outpatient clinic of the Dept. of Rhumatology med.of P hospital in Daegu, during 6 months from July 1, 2006 to December 31, 2006. The subjects were 140 cases : 80 cases from RA patients (60 women and 20 men; mean age 58 years; range, 32-68 years) confirmed by clinical diagnostic. 39 cases of these RA patients were classified as having early RA (EAC). 50 cases (non-RA) did not fulfill the criteria for RA, and 10 cases were from healthy individuals. We performed the analysis with solid phase-ELISA method (ETI-max3000, Diasorin; Italy) for anti-CCP and Nephelometry assay (Roche/Hitachi 902 analyzer; USA) for RF. The results obtained were summarized as follows ; anti-CCP ELISA is more specific than RF Nephelometry assay (specificity 94% vs 90%) to diagnose RA patients with suspected EAC (early arthritis clinic). The combination test "anti-CCP and RF" had a very high specificity (specificity 98.3%, PPV; RA group 96%, EAC 95%), the difference was statistically significant (p<0.05). Anti-CCP ELISA had more sensitivity in EAC (Early arthritis clinic) patients than chronic RA patients (sensitivity 64% vs 24%, respectively), anti-CCP of RA group and EAC group was more specific than RF (anti-CCP PPV; 92%, 89% vs 89%, 81% respectively), the difference was statistically significant (p<0.05). The difference of antibody concetration between anti-CCP and RF for RA and the control group is statistically significant (p<0.05). In conclusion, anti-CCP ELISA testing may be useful if performed concomitantly with RF Nephelometry assay to diagnose RA patients with suspected EAC (early arthritis clinic).

Background/Aims: Endoscopic resection has become the preferred treatment approach for select early esophageal adenocarcinoma (EAC); however, the epidemiology of early stage disease has not been well defined. Methods: Surveillance Epidemiology and End Results (SEER) data were analyzed to determine age-adjusted incidence rates among major epithelial carcinomas, including EAC, from 1973 to 2017. The percent change in incidence over time was compared according to tumor subtype. Early T-stage, node-negative EAC without metastasis was examined from 2004 to 2017 when precise T-stage data were available. Results: The percent change in annual incidence from 1973 to 2017 was 767% for EAC. Joinpoint analysis showed that the average annual percent change in EAC from 1973 to 2017 was 5.11% (95% confidence interval, 4.66%-5.56%). The annual percent change appeared to plateau between 2004 and 2017; however, early EAC decreased from 2010 to 2017, with an annual percent change of -5.78%. Conclusions: There has been a 7-fold increase in the incidence of EAC, which was significantly greater than that of the other major epithelial malignancies examined. More recently, the incidence of early EAC has been decreasing. Approximately one in five patients has node negative, potentially resectable early stage disease.

현재 국내 건설프로젝트에 EVMS가 도입되어 비용과 공정을 효과적으로 통합하여 관리하고 있으나 EVMS는 선진 외국의 건설환경에 적합한 방법으로서 이 EVMS를 국내에 적용하는 데에는 다소 어려운 점이 발견되고 있다. 본 논문에서는 EVMS에서 최종공사비(EAC)를 예측하는데 사용되고 있는 지수중의 하나인 합성지수(CI)의 가중치 n, m에 대한 통계적 분석을 통하여 신뢰구간상에 나타나는 합성지수(CI)를 검정하여 최종공사비(EAC)를 예측하는데 효과적으로 사용하고자 한다.

The EVMS(Earned Value Management System) comes from C/SCSC which was first released by the United States Department of Defense in December 1967, and preyed very powerful and efficient project management tool from a lot of practices. Although it is an excellent tool, we can not be succeed appling foreign system due to the differences of construction culture and law between the Korean and US construction industries. EAC(Estimate at Completion) is one of the most important functions in the EVMS. The purpose of this study is to propose the improved EAC method according to the performance indices better than old that and to prove from examples. In advance, the improved EAC method is to estimate more exactly costs and to promote efficiency in construction projects.

Primary tumors arising from the external auditory canal (EAC) are rare. We describe two cases of mass lesions within the EAC causing slowly progressive hearing loss without otorrhea or otalgia. Otoendoscopic examination demonstrated total obstruction of the EAC, and pure tone audiometry revealed conductive hearing loss. Based on the findings of the histopathologic examination, one patient was diagnosed with venous hemangioma that was treated using surgical resection, and the other patient was diagnosed with diffuse large B-cell lymphoma (DLBCL) that was treated using external-beam radiation therapy. Although primary tumors in the EAC are rare, both benign tumors such as venous hemangiomas and malignant lesions such as DLBCL should be considered as possible differential diagnoses of mass lesions in the EAC.

Globally, esophageal cancer is the seventh most common cancer, and the male-to-female ratio in esophageal adenocarcinoma (EAC) is significantly imbalanced at 4:1 to 8:1. Obesity, reflux, and smoking are known risk factors for this sex difference; however, fully explaining this remains challenging. Studies have investigated the link between exogenous sex hormones and esophageal cancer occurrence. A meta-analysis revealed a lower risk of EAC in female who had undergone hormone replacement therapy. Androgen-deprivation therapy in patients with prostate cancer was associated with a decreased risk of EAC. Tissue-based studies have reported varied results regarding the relationship between estrogen receptor expression and survival in female patients with esophageal squamous cell carcinoma (ESCC). Circulating hormone studies have suggested that higher testosterone and luteinizing hormone levels decreased EAC risk in men, and free testosterone was inversely correlated in female with ESCC. However, a high androgen-estrogen ratio in male patients with EAC was linked to increased odds of EAC. Sex hormones influence carcinogenesis, affecting cell proliferation, differentiation, metabolism, inflammation, and cell death. The studies were limited by the small sample size and varying hormone measurement methods; thus, future studies with definitive conclusions on the association between esophageal cancer and sex hormones are warranted.
