빅 데이터가 이슈화됨에 따라 데이터 분석의 결과를 기반으로 동작하는 많은 응용들이연구되고 왔고, 대표적인 응용들은 전자상거래 시스템의 상품 추천 서비스, 검색 엔진에서의 검색 서비스, 소셜 네트워크 서비스에서의 친구 추천 서비스 등이 있다. 본 논문은 기존의 데이터 마이닝 기법 중 데이터 집합에서 나타나는 유사한 패턴들을 마이닝하는 빈발 패턴 트리와 컴퓨터 과학의 이론에 기초한 결정트리를 결합하여 결정 빈발 트리 알고리즘을 제안한다. 이는 기존의 빈발 패턴 트리 알고리즘은 패튼 트리에서 패턴 생성에 대한 정확성은 보장되나 소셜 데이터처럼 다양한 패턴이 나타는 데이터에 대해서는 많은 수의 패턴들을 생성시켜 분석에 대한 어려움이 있어, 서브트리들과의 수렴 여부를 판단하는 모델로 변형시켜 문제를 개선한다. 또한 맵리듀스로 모델링하여 분산처리를 통한 고속 처리 알고리즘을 제시한다.

대학의 학사관리 시스템은 학생이 입학하여 졸업하기까지 수행하는 여러 가지 학사활동 및 과외활동으로부터 발생하는 방대한 데이터를 보유하고 있다. 그러나 이들을 학생들의 전공지도나 진로지도에 효과적으로 활용하지 못하고 있다. 본 논문에서는 학사관리 시스템에 축적된 정보를 대상으로 학생들의 전공선택 및 진로지도에 도움을 줄 수 있는 새로운 정보와 지식을 생성하는 방법을 개발, 제시하였다. 특히, 요인분석, 계층분석 (AHP) 기법을 동원하여 데이터 마이닝을 수행함으로써 유용한 지식과 규칙을 생성하였다. 방법론에 사용할 기본 자료는 학생들의 Holland 적성검사 결과이다. 연구의 결과로서 기존의 학생지도 담당자가 수작업으로는 알아낼 수 없었던 학생지도에 관한 유용한 규칙을 도출할 수 있었다.

Since 1998, government-led Korean venture business boom now proceeds into the stage of market-oriented venture business growth. At such a moment, this research is to clarify the relations between the Critical Success Factors of Korean venture businesses, based on domestic and foreign literature surveys and inquiry surveys over domestic venture capitalists. This research starts from the necessity to overcome the limits of the existing researches by uni-dimensional Korean venture businesses and to manifest the multi-dimensional relations between the success factors from the various viewpoints. And this research adopts System-Dynamics methodology to manifest and utilize relations among those factors, avoiding the existing metrical approaches. This research can be called a new approach to the current ecosystems of Korean venture in which whether venture businesses in Korea succeed is considered to depend on the list on the stock market. For this, this research implemented verification analysis through the simulations of each factor at various levels to build causality map which clarifies the causality of success factors of venture businesses through the System-Dynamics methodology and to utilize it as a way of support to decision-making of venture businesses. This research will be able to suggest the reactions depending on various internal and external situations. This research tried to manifest the causality map of each factor on the basis of inquiry surveys and literature surveys to clarify Feedback among each factor by the SD methodology and simulate it. This research will be a basis to establish the chance to bolster up the still fragile probing research into success factors of substructure of venture businesses through the suggestion of possibility as an efficient analysis framework via the verification of SD methodology and the utilization of results of this research.

Computerization is recognized as simple supporting tools up to recently but Information is made for the improvement of company's outcome beyond the assistant tools and is emerged as core tools of creating new opportunities for company in point of management strategy. But Information plays minor role in Korean Institute of Oriental Medicine(KIOM) yet. Information has not processed systematically because of lack of understanding and budget in KIOM. The purpose of this research is to make plan for knowledge information which is aimed to make effective supporting and strengthening the ability of KIOM's research, until 2013. Also we tried to find new project s for information and to apply the result to planned information projects. The final goal of this study is to make mid/long-term information plan of KIOM. We applied the general information strategy planning(ISP) method which is progressed as analysis of information technology, analysis of information status, design of future model and extraction of action plan order. First, we examined the information elements for the advanced management from analysis of management environment and analyzed information technology trends. Second, we list up the gaps and problems of KIOM's information status and define the future model to solve this problems. It is showed the road map of time and budget for future model to progress systematically inner-information of purpose. We hope that information of KIOM will be conducted successfully.

컴퓨터 게임 배경이 정교하게 표현되면서 그리드 기반으로 표현된 게임 맵에서 $A^*$ 알고리즘을 이용한 경로 찾기는 전체 게임 성능을 저해하는 요인이 되고 있다. 셀 단위의 세밀한 표현으로 상태 공간이 커져 탐색 시간이 증가하기 때문이다. 본 논문에서는 정규 그리드로 표현된 컴퓨터 게임 배경을 꼭지점 리스트로 된 다각형 기반 맵으로 변환하고 다각형의 꼭지점에 대한 가시성 정보를 이용하여 효율적인 경로 찾기가 가능하게 하는 방법을 제안한다. 다각형 기반 맵으로의 변환은 오프라인으로 전처리하여 실시간 쿼리에는 영향을 미치지 않도록 하며 꼭지점의 가시성 정보를 이용하는 휴리스틱을 설계함으로서 추정의 정확도를 높여 경로 탐색 시에 방문하는 노드수를 획기적으로 감소시키도록 한다. 시뮬레이션에서는 제안한 방법들이 그리드 기반 방식의 장점을 유지하면서 탐색 공간과 탐색 시간을 효율적으로 감소시킴을 확인한다.

The purpose of this study is to develope a CAD-based tool for rasterization of polygonal vector map in AutoCAD. To identity the layer property of polygonal entity with user-defined coordinates as topology, algorithm in processing entity data of selection set that intersected with scan line was used, and the layers were extracted sequentially by sorted intersecting points in data-list. In addition to the functions for querying and modifying topology, two options for mapping were set up to construct plan projection type and to change meshes' properties in existing DTM data. In case of plan projection type, user-defined cell size of 3DFACE mesh is available for more detailed edge, and topological draping on landform can be executed in case of referring DTM data as an AutoCAD's drawing. The concept of algorithm was simple and clear, but some unexpectable errors were found in detecting intersected coordinates that were AutoCAD's error, not the utility's. Also, the routines to check these errors were included in algorithmic processing. Developed utility named MESHMAP was written in entity data control functions of AutoLISP language and dialog control language(DCL) for the purpose of user-oriented interactive usage. MESHMAP was proved to be more effective in data handling and time comparing with GRIDMAP module in LANDCADD which has similar function.

The objective of this study is to develop and present the modern men's hip-hop fashion designs using the design elements of Hanfu which is a traditional culture of China as a motif by applying the SCAMPER technique. In the research methods, this study conducted the literature review and work production. In the process of work development, first, after setting up the concept, a design map was produced. Second, the characteristics of hip-hop fashion style and the design elements of Hanfu were organized. Third, this study developed the hip-hop fashion designs reinterpreting the design elements of Hanfu into modern hip-hop styles by applying the SCAMPER conception list. Fourth, Fourth, of the developed designs, the finally decided upon designs were produced into real six articles, which included a T-shirt, shirt, zippered sweater, jumper, denim jacket, long jumper, denim pants, baggy pants, and short pants. This study offers the possibility of developing Chinese hip-hop fashion design targeting the emerging Chinese hip-hop fashion market by suggesting hip-hop fashion designs with the characteristics of Chinese traditional culture.
