The National Museum of Contemporary Art, Korea began operating the museum archives in October 2013. Although the museum archives have an independent flow that is distinct from discussions of the archival sciences, it is a reality as a record management organization, and therefore, access to and analysis from the viewpoint of archival science is required for efficient operation. The purpose of this study is to diagnose the method of collecting and organizing records from the viewpoint of archival sciences from the Institutional Archives of the National Museum of Contemporary Art, Korea. To this end, we theoretically examined the function of the museum, the role of the museum archives, and the scope and method of collection and arrangement of the museum archives. Based on these discussions, we analyzed the scope of the collection and the system of arrangement of the institutional archives. Then, we suggested some improvement plans.

일반적으로 확률강우량은 관측된 강우자료의 분석을 통해 산정하게 된다. 관측된 강우자료의 빈도해석을 통해 산정된 확률강우량은 기후변화 등을 반영하기 매우 어렵다. 따라서 본 연구에서는 통계적 기법을 이용하여 수문기상인자를 반영하여 서울지점의 확률강우량을 산정하였다. 수문기상인자와 연최대시간강우량사이의 상관관계에 기초하여 확률강우량을 산정할 수 있는 CPPM(Climate Pattern and Precipitation Model)을 구축하고 서울 지점을 대상으로 분석을 수행하였다. 분석결과에서 매개변수적 지점빈도해석의 결과와 CPPM 확률강우량은 비슷한 Qunatile을 산정하는 것으로 나타났다. 또한 본 연구의 결과를 지구온난화 등에 따른 기후변화에 따라 극한강우인 연최대강우량의 변화를 예측하는데 있어 기초자료로 활용 할 수 있을 것으로 기대 된다.

현대 사회가 점점 복잡한 정보화 사회로 변해감에 따라 개인의 자료 또한 기존의 방법으로는 효율적인 관리가 어렵게 되었다. 이러한 상황속에서 연구소 및 대학 연구원들의 늘어나는 연구실적을 효율적으로 관리하기 위하여 본 논문에서는 연구원들의 연구실적을 컴퓨터에 저장하여 효율적으로 관리할 수 있는 연구실적관리시스템(RAMS : Research Accomplishment Management System)을 설계, 구현하였다. 본 시스템은 연구실적을 효율적으로 관리할 수 있도록 각 연구실적에 관한 원시자료만을 입력시킨 후 이를 이용하여 원하는 내용의 연구실적을 조회하고, 각 연구실적별 내용을 원하는 양식에 맞게 출력을 할 수 있게 해주었으며 또한 개인별 실적관리 뿐만 아니라 소규모 집단(연구소)에서의 개인별 관리를 용이하게 하기 위하여 개인화일을 코드화해서 관리해주는 기능을 가지도록 하였다.

신속조형시스템(RP : Rapid Prototyping)용 자료교환 표준인 STL의 자료구조는 단순하고, 조형용 2차원 단면 자료로의 전환이 용이하며, 생산 가공 기술로서의 현대적인 특성(신속성, 조형성, 경제성, 청정성 등)을 가지고 이는 장점이 있는 반면에, STL 3D 좌표값의 기준(좌표계의 원점)이 되는 크기 정보가 없다. 이런 문제를 구현된 STL 뷰어에서는, 스케일링(scaling) 기법과 선형적인 이동 기법을 사용하여 해결하였고, CAD 시스템으로 제작된 파일 자체의 문제점 패싯(facet) 중복, 정밀도, 법선 벡터 값의 오류 등도 검증기(verifier)와 오류 정정기(error corrector)글 구현하여 해결하였다. 제안된 방법으로 구현된 STL 뷰어는 시스템의 안정성과 확장성, 그리고 효율성 측면에서 우수한 성능을 보였으며, 슬라이싱(slicing), 경로 추적기(path tracer)의 전처리기의 역할을 한다.

Modern war is called as information war. So an Information Systems which operate hitech-weapon is evaluated important by the ARMY. As terrain analysis techniques we an essential element, computer-based terrain analysis techniques for the army are developed. This paper studies the method of tactical terrain analysis data base construction and presents cross-country mobility after analysis officer analysis overlayed terrain data. Also, Terrain information data base construction method is presented through this analysis, which planned a suitable plan of operations in order to mission accomplishment in normal times.

일본에서 발행한 1885년부터 1945년까지의 역서를 같은 기간 동안 한국에서 발행한 역서에 대한 선행 연구 결과와 비교 분석하였다. 이 무렵 한국에서는 갑오개혁(1894), 태양력 시행(1896), 일제 강점기(1910-1945) 등의 많은 역사적 사건들로 인하여 역서 발간 업무를 담당하던 기관과 역서의 내용에 있어서도 여러 가지 변화가 있었다. 반면 일본에서는 메이지유신(1868) 이후인 1873년부터 태양력을 시행하였으며, 1888년에는 동경제국대학 부속 동경천문대가 설립되어 1890년부터 역서 자료를 편찬했었다. 특히 비교 기간 동안 일본에서는 '본력(本曆)'과 본력의 중요한 내용만을 수록한 '약본력(略本曆)'이라는 두 종류의 역서가 발행되었으며, 이 연구에서는 약본력을 주로 사용하였다. 수집한 자료를 가지고 한국과 일본에서의 역서 발행 기관, 표준자오선의 변경, 일력계산의 기준위치 등에 대한 비교 연구한 결과를 제시하고자 한다. 아울러 몇몇 연도에 대해서는 두 나라 역서에 게재된 일력자료를 상호 비교 하였고, 특히 합삭시각에 대해서는 현대 계산 결과와도 비교하였다.

Unknown geotechnical characteristics are key challenges in the design of piles for the plant, civil and building works. Although the N-values which were read through the standard penetration test are important, those N-values of the whole area are not likely acquired in common practice. In this study, the N-value is predicted by means of regression analysis with artificial intelligence (AI). Big data is important to improve learning performance of AI, so circular augmentation method is applied to build up the big data at the current study. The optimal model was chosen among applied AI algorithms, such as artificial neural network, decision tree and auto machine learning. To select optimal model among the above three AI algorithms is to minimize the margin of error. To evaluate the method, actual data and predicted data of six performed projects in Poland, Indonesia and Malaysia were compared. As a result of this study, the AI prediction of this method is proven to be reliable. Therefore, it is realized that the geotechnical characteristics of non-boring points were predictable and the optimal arrangement of structure could be achieved utilizing three dimensional N-value distribution map.

The astronomical data obtained by observations of celestial objects movements are useful in our daily life. These data - such as 1) sunrise and sunset data, 2) data transformation between lunar calendar and solar calendar, 3) solar eclipse and lunar eclipse data, and 4) sun's altitude and azimuth data - were used to important things in the agricultural society and ancient kingdom. In the modern society, these data have been used continuously for the legal disputes, construction of buildings and the other areas. This is a good example of pure science data using directly in our life. However there are difficulties to public service because all the data were printed as an Almanac. Using MySQL, we constructed web-based service system which makes to use them easily. This database system was made for the quick search using the calculated orbital data of celestial bodies.

This study aims to develop items to diagnose pre-service physics teachers' understanding of the conceptual knowledge of modern physics, based on the achievement criteria presented in the 2015 revised national science curriculum, and to identify the validity and reliability of the newly developed items. Data were collected from 467 pre-service physics teachers in the Physical Education Department or Science Education Department (Physics Education Major) of 15 universities across the nation. In this study the content validity, substantive validity, the internal structure validity, generalization validity, and the external validity proposed by Messick (1995) were examined by various statistical tests. The results of the MNSQ analysis showed that there was no nonconformity in the 23 items. The internal structure validity was confirmed by the standardized residual variance analysis, which shows that the 22 items was unidimensional. The generalization validity was confirmed by differential item functioning (DIF) analysis about groups lectured or not modern physics/quantum mechanics. In addition, item analysis and test analysis based on classical test theory were performed. The mean item difficulty is 0.66, mean item discrimination is 0.47 and mean point biserial coefficient obtained was 0.41. These results for item parameters satisfied the criteria respectively. The reliability of the internal consistency of the KR-20 is 0.77 and the Ferguson's delta obtained was δ = 0.972. By Rasch model analysis, the item difficulty (item measures) was discussed.

Modern cultural heritage were made with various materials. But there are no certain analysis for modern cultural heritage. Analysis on rickshaw from National Museum of Korean Contemporary History were carried out using P-XRF, species identification, paint film analysis, FT-IR and microscope observation. As a result Copper and Zinc were measured in metal parts. Nickel alloys were first used in the modern era for rickshaw. Wooden parts, Oak(Quercus spp.), bamboo(Phyllostachys spp.) and Hinoki cypress(Chamaecyparis spp.) were identified. Outer films were painted by 5 layers and inner films were painted by 3 layers. More simple painting process were performed on the inner part. Cotton and wool were identified by FT-IR. Also, cowhide were identified. Authenticity conservation and restoration could be carried out with the results.
