Recent business environments require a company to communicate frequently with other companies. This makes it essential to use XML (extensible Markup Language) documents. Especially in e-Business environments, change management of documents is important to record and trace the history of the documents. It is also important to reconstruct a certain version of documents that are exchanged among companies. In this paper, we propose a new method of storing a document by detecting changes automatically and reconstructing the document version when a user requests. A prototype system is implemented on top of a workflow system. Our approach provides efficiency of storage space and convenient management of documents.

This study considers the local players in the European steel industry, whose the amounts of crude production are more or less 5 million tons per annum. They do not belong to the Pan-EU mega-group of steel mills with more than 15 million tons of crude production yearly. However, these mid-sized steel mills in European countries have been originated from the strong foundation of steel, scientifically and technically, as well as the centennial history. They concentrate on the niche market adjacent to the local area, which takes advantage of the geographical location. The companies considered here are VoestAlpine in Austria, Salzgitter in Germany, Rautaruukki in finland, and SSAB in Sweden. Their corporate strategies are compared on the basis of product mix and sales structure. And, the deep analysis for each company is performed, such as business strategies with the sales volumes, market strategies. competitiveness improvement planning. and R&D policies with the technology management. These analysis results can be benchmarked as the cases of best practices for domestic steel mills, especially mid & small sized companies, that develop business and market strategies for the sustainable growth and profitability.

장소 마케팅이란 특정 장소를 하나의 상품으로 인식하도록 기업과 주민, 관광객이 선호하는 이미지와 제도, 시설 등을 통해 장소의 상품가치를 제고하는 것이다. 이러한 개념을 철도에 적용하여 새로운 지역발전의 전략을 모색할 수 있다. 폐지선과 영업 정지 역을 활용하여 새로운 지역 개발의 기회로 삼는 사례들이 이러한 맥락이다. 나아가 관광, 여가 문화, 지역축제를 철도와 연계할 필요가 있다. 이를 위해서는 지방자치단체와의 협력이 필요하다.

Online search has recently become a popular business research field not only because the search volume is used to predict demand, but also consumer search history is effective to predict product prices and investment returns. This study analyzes the relationship between the Internet search volume of IPO stocks and their post-IPO stock returns in Korean Exchange. We find that the lower the amount of Internet search for stocks before IPO, the higher the stock returns after IPO both in short and long-term. Similar results are shown for excess returns over benchmark stocks. This finding suggests that IPO stocks with low investors' attention based on the Internet search volume may be undervalued.

In this paper, we propose personalized recommendation techniques based on multidimensional scaling (MDS) method for Business to Consumer Electronic Commerce. The multidimensional scaling method is traditionally used in marketing domain for analyzing customers' perceptional differences about brands and products. In this study, using purchase history data, customers in learning dataset are assigned to specific product categories, and after then using MDS a positioning map is generated to map product categories and alternative advertisements. The positioning map will be used to select personalized advertisement in real time situation. In this paper, we suggest the detail design of personalized recommendation method using MDS and compare with other approaches (random approach, collaborative filtering, and TOP3 approach)

원 업무 효율성을 높이기 위해 최근 다양한 병원 정보 시스템들이 도입되어 왔다. 이러한 시스템들을 통해 병원에서는 다양한 데이터를 전자적인 형태로 기록하고 공유하고 있으나, 이러한 데이터들은 일반적으로 간단한 통계량을 집계하는 데에만 사용되고 있어, 보다 체계적인 방법으로 병원 운영 관리에 유용한 숨겨진 지식이나 패턴을 추출하는 방법이 필요하다. 이에 본 논문에서는 기존 병원 정보 시스템들에 의해 축적되어진 환자 이력 데이터를 분석하여 임상 서비스 프로세스 모형을 추출하는 방법을 제안한다. 환자 이력 데이터는 검사나 처방 등을 실시한 기록을 포함하는데, 일반적으로 구조가 복잡하고 데이터 소스가 분산되어 있어 단순한 방법으로 분석하는 것이 까다롭다. 따라서, 본 논문에서는 먼저 단순한 형태의 프로세스 모형을 생성하고 이를 확장해나가는 단계적인 분석 방법을 소개한다. 이러한 목적을 위해 적절한 데이터 전처리, 데이터 마이닝, 프로세스 마이닝 기법 등이 활용되었으며, 제안하는 방법을 실제 류머티스과 환자 이력 데이터에 적용하여 임상 서비스 프로세스 모형을 추출할 수 있었다.

The purpose of this study was for analyzing the fashion design imaged by Kimono in the 1990s. Through the work, what is the way to create the non-western fashion design can be found. For this purpose, I took my design data from fashion magazines in the 1990s, and referred to the literal materials about history of western costume and Kimono. The result were as follows ; Kimono in Japanese denotes thing to wear. Ki is derived from the verb kiru, to wear, and mono, thing. However, in the western world the term came to mean the T-shaped outer garment formerly known in Japan as the kosode. It is consists of sleeve(sode), wide sash(obi), hemline(suso), collar(eri), and material. There were many complex reasons for its diversity in the west, and for its evolution during the past one hundred years from the peignoir including exoticism, eroticism, women's liberation to the high fashion imaged by folklore and avant-garde. Therefore the fashion design imaged by Kimono was divided into feminine style, natural & folklore style, modern & avant-garde style.
