Purpose: Introducing CR (Computed Radiography) system created a process of printing therapy irradiation images and converting the degree of enlargement. This is to increase job efficiency and contribute to work improvement using a computerized method with home grown software to simplify this process, work efficiency. Materials and Methods: Microsoft EXCEL (ver. 2007) and VISUAL BASIC (ver. 6.0) have been used to make the software. A window for each shield block was designed to enter patients' treatment information. Distances on the digital images were measured, the measured data were entered to the Excel program to calculate the degree of enlargement, and printouts were produced to manufacture shield blocks. Results: By computerizing the existing method with this program, the degree of enlargement can easily be calculated and patients' treatment information can be entered into the printouts by using macro function. As a result, errors in calculation which may occur during the process of production or errors that the treatment information may be delivered wrongly can be reduced. In addition, with the simplification of the conversion process of the degree of enlargement, no copy machine was needed, which resulted in the reduction of use of paper. Conclusion: Works have been improved by computerizing the process of block production and applying it to practice which would simplify the existing method. This software can apply to and improve the actual conditions of each hospital in various ways using various features of EXCEL and VISUAL BASIC which has already been proven and used widely.

대용량 문서 데이터베이스를 위한 효율적인 점진적 문서 클러스터링 기법
강동혁,주길홍,이원석,Kang, Dong-Hyuk,Joo, Kil-Hong,Lee, Won-Suk 한국정보처리학회 2003 정보처리학회논문지D Vol.10 No.1
With the development of the internet and computer, the amount of information through the internet is increasing rapidly and it is managed in document form. For this reason, the research into the method to manage for a large amount of document in an effective way is necessary. The document clustering is integrated documents to subject by classifying a set of documents through their similarity among them. Accordingly, the document clustering can be used in exploring and searching a document and it can increased accuracy of search. This paper proposes an efficient incremental cluttering method for a set of documents increase gradually. The incremental document clustering algorithm assigns a set of new documents to the legacy clusters which have been identified in advance. In addition, to improve the correctness of the clustering, removing the stop words can be proposed and the weight of the word can be calculated by the proposed TF$\times$NIDF function. 컴퓨터의 발전과 인터넷의 급속한 발전으로 정보의 양이 폭발적으로 증가하게 되었고 이러한 방대한 양의 정보들은 대부분 문서 형태로 관리되고 있으며, 문서 단위별 표현된 많은 정보들을 효과적으로 관리하고 검색하기 위한 방법의 연구가 필요하게 되었다. 문서 클러스터링은 문서간의 유사도를 바탕으로 서로 연관된 문서들을 군집화하여 문서들을 주제별로 통합하는 방법으로 대용량의 문서들을 자동으로 분류하고, 검색하는 데 있어서 검색의 정확성을 증대시킬 수 있다. 본 논문에서는 새로운 문서의 추가나 기존문서의 삭제로 인하여 군집화 대상이 되는 문서 집합이 점진적으로 변화하는 환경을 위한 점진적 문서 클러스터링 알고리즘을 제안한다. 점진적 문서 클러스터링 알고리즘은 새로운 문서가 추가되었을 경우 문서 전체를 다시 클러스터링하지 않고, 이미 생성된 클러스터들의 구조를 적극적으로 변화시킴으로써 높은 효율성을 제공할 수 있다. 또한, 문서 클러스터링의 정확도를 높이기 위하여 통계적인 기법으로 불용어를 판별하여 제거하는 알고리즘을 제안하고, 문서 클러스터링에서 정확한 단어가중치 산출을 위해 TF$\times$IDF 공식을 수정한 TF$\times$NIDF 공식을 제안한다.

문화복합시설로서의 풍납토성 매장문화재 보존에 관한 연구
강동혁(Kang, Dong-Hyuk),김소영(Kim, So-Young) 대한건축학회 2024 대한건축학회 학술발표대회 논문집 Vol.44 No.1
Should history with hidden urban heritage and artifacts be forgotten? As cities grow and develop, these hidden ruins are inevitably revealed to us. Is it right to erase all traces of our history in order to make room for new developments? Is it appropriate to cover up an excavation once a buried heritage is revealed? My research and paper on the urban ruins of the Forgotten Kingdom will explore howarchitecture and these historical buried ruins can coexist and how we can preserve the memory of the old and the new with a new cultural complex in Pungnapdong. As we have seen in China’s Northeast Project, we need to rethink our perception of preserving history and culture.
