With the revision of the Public Records Management Act in 2020, it has become possible to appraise long-term records more than 30 years old in the record center. However, there was no discussion on the appraisal process except for the revision of the Public Records Management Act. This study aimed to propose a process for appraisal of long-term records in the record center, focused on the roles and functions of the record center, archives, and central archives. To confirm the status and problems of the records appraisal process, we analyzed record management standards and interviewed 4 archivists who have been working as specialists for over 10 years. Based on the analysis results, the appraisal process for long-term records in the record center was redesigned in consideration of the functions and roles of the record center, archives, and central archives.

체내방사능 측정시스템의 교정인자는 측정결과에 주요한 요인으로 작용한다. 교정인자는 특정 집단으로부터 표준체위와 표준장기를 도출, 이를 기초로 하여 제작한 펜텀으로부터 구하는 것이 일반적인 방법이다. 그러나 팬텀의 기하학적 구조 및 내부장기의 형상은 특정 집단에 따라 다르므로 이로 인한 측정오차가 발생할 수 있다. 따라서 본 연구에서는 북아메리카 성인남성의 표준자료에 근거하여 제작된 LLNL 팬텀과 일본성인 남성의 표준자료에 근거하여 제작된 JAERI 팬텀을 한국원자럭연구소 폐 카운터를 이용하여 상호비교.분석하였다. 이와 함께 LLNL 팬텀으로 교정된 폐 카운터의 성능시험을 JAERI 팬텀으로 DOELAP 성능시험범주 I, II, III 및 IV에 대해 수행하여 편텀의 구조 및 형상으로부터 발생하는 측정오차를 분석하였다. 비교.분석결과 1.7 cm ~ 3.7 cm 근육등가 가슴벽두께 범위내에서 JAERI 팬텀에 의한 교정인자가 전반적으로 LLNL 팬텀의 것보다 다소 높은 수치를 보였으나 허용수준이었고, 성능시험결과 상대편중은 DOELAP 성능 용인 기준을 만족하였다. 결국 두 팬텀간의 측정오차는 측정 및 체내피폭선량 평가시 수반되는 오차와 비교해 보면 그다지 크지 않은 것으로 결론지울 수 있다. 따라서 LLNL 펜텀으로부터 구한 교정인자를 국내 성인남성의 일상 모니터링에 사용할 경우 측정결과가 다소 과대평가되기는 하나 허용수준으로서 큰 문제가 없는 것으로 나타났다.

최근에 이슈화되고 있는 녹색기술문헌의 중요성에 부합하여 녹색기술 문헌을 자동으로 분류해주는 문서 분류시스템 개발하였다. 분류체계로는 14개의 관심 녹색기술 분류 체계를 선택하였고, 다양한 문서 분류 기법 중 SVM(Support Vector Machine)에 기초를 둔 방법을 이용하였다. 문서 벡터를 생성할 때 제목과 본문에 동일한 가중치를 적용하는 방법을 벗어나서 제목의 키워드에 좀 더 높은 가중치를 부여하는 방식을 적용하여 성능평가를 수행하였다.

The purpose of this study is to investigate the determinants of the quality of Web-based legal information services and their significant influences on the user continuance intentions. Based on the main dimensions of the SERVQUAL, this study conceptualizes five dimensions of reliability, assurance, design, empathy, and responsiveness. It measures the level of expectation and satisfaction on the basis of these five dimensions. Regression analysis was conducted to extract and analyze the determinants of the service quality and the factors affecting continuous intention. The level of legal information service quality is superior in empathy, responsiveness, and design category, but it is relatively insufficient in reliability and assurance category. In the reliability category, the relevance of the search results was an issue. The problems related to the authority and information sources were recognized as important. Reliability implies that there is a relatively close relationship between empathy and responsiveness, and that it is necessary to improve the quality of contents such as empathy and responsiveness in order to increase reliability. In order to increase the ongoing use of legal information services in the future, it is more effective to make sure that assurance is top priority.

In this study, we link informal Web resources to KISTI NDSL's collections using automatic semantic indexing and tagging to examine the possibility of the service which recommends related documents using the similarity between KISTI's formal information resources and informal web resources. We collect and index Web resources and make automatic semantic linking through STEAK with KISTI's collections for NDSL retrieval. The macro precision which shows retrieval precision per a subject category is 62.6% and the micro precision which shows retrieval precision per a query is 66.9%. The experts' evaluation score is 76.7. This study shows the possibility of semantic linking NDSL retrieval results with Web information resources and expanding information services' coverage to informal information resources.

There are many occasions that the performance of a corps is influenced not only by its own efforts but by the commander of the next higher unit in a vertical organizational structure. When the direction of the commander in the next higher organization is different from that of the actual evaluation agency, the unit under evaluation may get rated lower than what it should deserve. This study suggests an alternative method to evaluate the performance of military units in the situation that there exist critical environmental factors which affect the performance. This method employes DEA, a non parametric method, and Constrained Canonical Correlation Analysis(CCCA), a parametric method which is used to estimate a efficient frontier with multiple dependent variables and constraints. This article also exploits a set of categorical environmental variables in the CCCA to improve the fairness of performance evaluation. It is shown that the introduction of the categorical variables helps evaluating the true performance of individual units such as battalions subordinated to different next higher commanders.

This is a qualitative study to explore the experiences of convergence external appraisal of competency in core basic nursing skills in final year nursing students. Eight nursing students who experienced the evaluation were intentionally sampled. Data were analyzed using constant comparative and categorical content analysis after collecting data through focus group interview. The results of this study showed that nursing students sublimated mental stress such as burden and pressure of the evaluation into a positive experience that they skillfully improved their nursing skills through mind control and cooperation with peers. Therefore, this study enabled us to understand the experience of students receiving external appraisal. In addition, intervention studies to alleviate mental stress on convergence external appraisal are needed.

In this study, Material life cycle evaluation was performed to analyze the environmental impact characteristics of TiN-Zr membrane manufacturing process. The software of MLCA was Gabi. Through this, environmental impact assessment was performed for each process. Transition metal nitrides have been researched extensively because of their properties. Among these, TiN has the most attention. TiN is a ceramic materials which possess the good combination of physical and chemical properties, such as high melting point, high hardness, and relatively low specific gravity, high wear resistance and high corrosion resistance. With these properties, TiN plays an important role in functional materials for application in separation hydrogen from fossil fuel. Precursor TiN was synthesized by sol-gel method and zirconium was coated by ball mill method. The metallurgical, physical and thermodynamic characteristics of the membranes were analyzed by using Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDS), X-ray Diffraction (XRD), Thermo Gravimetry/Differential Thermal Analysis (TG/DTA), Brunauer, Emmett, Teller (BET) and Gas Chromatograph System (GP). As a result of characterization and normalization, environmental impacts were 94% in MAETP (Marine Aquatic Ecotoxicity), 2% FAETP (Freshwater Aquatic Ecotoxicity), 2% HTP (Human Toxicity Potential). TiN fabrication process appears to have a direct or indirect impact on the human body. It is believed that the greatest impact that HTP can have on human is the carcinogenic properties. This shows that electricity use has a great influence on ecosystem impact. TiN-Zr was analyzed in Eco-Indicator '99 (EI99) and CML 2001 methodology.

수질오염총량관리제 시행 하천에 대해서는 객관적이고 과학적 방법으로 유역내 각 지역의 오염부하량을 할당할 필요가 있다. 본 연구에서는 대도시에서 배출되는 오염부하의 영향을 크게 받는 영산강수계의 중상류부를 대상으로 오염부하량 할당 방법에 대해 검토하였다. 오염부하량 할당을 위한 수질모델링은, 수질관리에 흔히 적용되어온 QUAL2E의 최근 판인, QUAL2Kw를 이용해서 수행하였다. 모델 적용 대상 지역의 각 reach의 수질매개변수는 QUAL2Kw의 자동보정 기능을 이용해서 추정하였다. 오염부하량 할당의 최적화는 유전알고리즘(genetic algorithm)을 이용하였고, 최소부하량 삭감법(least waste load removal allocation), 일정 부하량 이상 최소부하량 삭감법(least waste load removal over a certain value), 동일삭감률 할당법(equal removal rate)의 세가지 방법을 적용하고 비교 검토하였다. 동일삭감률 할당법은 다른 방법보다 유역 전체 부하량 삭감량이 훨씬 크기 때문에 효과적이지 않았고, 이 방법을 쓰기 위해서는 부하량 삭감대상인 각 소유역과 하수처리장을 그 규모와 특성에 따라 세분화할 필요가 있다. 동일삭감률 할당법의 적용시 세가지 범주로 나누어서 삭감률을 적용하였다. 오염부하량 삭감의 효율성을 감안할 때 최소 부하량 삭감법보다 일정 부하량 이상 최소부하량 삭감법이 더 적절한 것으로 검토되었다.

지리산왕등재 습지의 바람직한 관리를 위하여 미국야생생물보호청(US Fish & Wildlife Service)에서 개발한 습지 유형 분류방법론을 적용하여 유형분류와 평가를 수행하였다. 지리산왕등재 습지는 계(System), 아계(Subsystem), 강(Class), 아강(Subclass), 수영역(Water Regime), 수문지형 단위 (Hydrogeomorphic Units), 저질/우점유형 (Substrate/Dominants Type)의 계층적 분류체계에 따라 소호소습지생태계(Palustrine wetland system), 정수습지생태계 강, 영속형 정수식물 습지생태계 아강, 영구적으로 습윤한 수영역, 범주성 수화학(pH 6.1), 산악의 영구적인 초원 수문지형, 저질은 유기체 유형(이탄토)으로 사초과와 고랭이속이 우점하는 습지로 분류되었다. 지리산 왕등재 습지와 비교하여 대암산 용늪의 분류체계는 이끼/지의류 강, 이끼 아강, 영구적으로 습윤한 수영역, 산성의 수화학, 저질은 유기체 유형(이탄토)으로 물이끼가 우점하고 관속식물이 혼재하는 유형으로 분류되어 많은 차이가 난 반면, 무제치늪은 매우 유사한 습지유형으로 우점유형(진퍼리새 우점)과 특정 종에서만 차이가 났다.
