We live in an age which is exponentially growing as the knowledge paradigm is changing. New sites are subject to contemporary landscape architecture function as "fields" in which this hybrid aspect is both actively practiced and becoming a catalyst for change in the area of landscape architecture. With this as its background, this study attempts to deal with how the aspect of integration in environmental design is manifested. For this purpose, the tendencies for the discussion of integration in various fields of practice were examined: planning theories, urban theories, architecture, public environment, engineering, and landscape architecture. As yet, the discussions of interdisciplinary integration, which occur in practice in these respective fields, mainly tend to be oriented toward the effective implementation of the merits of other related fields. Seen from these examples of practice, integrated design approaches can be found in the following three aspects: design objects, respective professional areas, and methodologies of approaches and design. In terms of design objects, the positions of individual design subjects present themselves as most obvious, and integration or combination of the physical targets that come to exist through design can be easily seen. Most examples of integration turn out to be this, in almost every case of which the theme and the target of expression are integrated via a small number of certain methods. In terms of professional areas, what can be mainly evidenced is how the individual subject acts when the subject designs. The strong points of professionals from each field seem to create synergy, achieving through integration optimum results. In terms of methodologies of approaches and design, there are attempts to create integrated approaches as ways of effective decision-making, in which case the integration of all of the interest parties is of primary concern. As yet, few instances have been found in which integrated design has had enough strength to be seen as a concrete design methodology based on practical examples. However, it is encouraging that theoretical approaches and the necessity for integrated design have been identified from multiple perspectives, and that a practical movement such as landscape urbanism has come into active being. The authors of this study find this point in time to be ripe for discussions on integrated practices in terms of environmental design, on the basis of the synthetic approaches mentioned above.

For the implementation of science and technology based agriculture, one of the domestic rural development strategies, it is essential that we should have an integrated information system for each crop production. This system would be a web-based collaborative system for the local farmer and the advisors who guide the crop production technically, and would be capable of providing the real-time analysis functionalities and expert knowledge. In this thesis, we proposed a component based development methodology called MCPI(Method for Crop Production Information system) which employs and re-organizes Marmi-III, the popular existing component based methodology for the large scale S/W development project. In particular, MCPI is designed to reflect the characteristics of crop production information system and for the small and medium S/W project. To show the applicability in real-world problems, we develop and evaluate a prototype which is based on our proposed methodology for the rice production farmer in mid-Choongnam area.

최근 제조 기업들의 가장 큰 화두 중 하나는 제품과 서비스의 통합이다. 그간 제품과 서비스 통합과 관련한 다양한 개념들이 제시되어 왔으나, 정의 및 유형에 대한 보편적인 프레임워크가 존재하지 않는다. 본 연구에서는 제품과 서비스의 통합에 관련된 다양한 개념들을 아우르는 포괄적인 용어 (umbrella term)로써 통합 제품-서비스(integrated product-service: IPS)를 제시한다. 기존 문헌 연구를 통해 IPS 관련 기존 개념들을 개괄하고, 이들을 Product/service fusion과 Product/service Convergence의 두 가지로 분류한다. 다음으로 IPS를 유형화하기 위한 분류체계(typology)로써 IPS 큐브(cube)를 제시한다. IPS 큐브는 통합의 형태(pattern), 원천(origin), 기술(technology)의 세 가지 차원으로 구성되며, 각 차원이 모두 세 가지 유형으로 구분되기 때문에, IPS 큐브는 27개의 셀로 이루어진 정육면체 형태를 띤다. 각 셀은 고유한 IPS 유형을 나타내며, 각 셀에 해당하는 실제 IPS 사례들이 제시된다. 본 연구에서 제시한 IPS 큐브는 유형별 IPS 개발을 위한 전략, 프로세스, 방법론을 개발하는데 있어서 유용한 시사점을 제공해줄 수 있다.

This research is to offer a structured yet practical ex-ante evaluation methodology for IT investment. Benchmarking the best practices of four Korean organizations, we try to integrate core processes, relevant measures, and evaluation dimensions into a consistent and wholesome body of evaluating methodology. The best practices we considered encompass a wide range of business enterprises, including for-profit, non-profit, service-oriented, and manufacturing entities. The proposed methodology consists of three stages; the first stage checks the validity of investments by looking into comprehensiveness of planning, willingness to accomplish, justifiable grounds for the investments, overlapping investments, and obstructing risks; the second do so by putting an IT investment into economic, strategic, and technological perspectives; and the last third would produce a unified quantity that summarizes outcome of the previous stages. Incorporating the proven knowledge, guidelines, and quantifying tools, the methodology could make a valuable reference model for IT evaluation practitioners who have been bedeviled by having to going through such ex-ante evaluations.

Product array approach which is used in the Taguchi parameter design has a number of advantages by considering the noise factor. However, a disadvantage of this method is that it requires an excessively large number of experiments. So combined array approach have been proposed to reduce the number of experiments. Taguchi has used the signal-to-noise ratio to find the optimum conditions in the Taguchi parameter design. In analyzing the data from the parameter design various problems tends occur by using an SN. In this paper, we propose an alternative solution for reducing the number of experiments without depending on the signal-to-noise ratio to overcome the shortcomings of the parameter design. Two examples illustrate this procedure in the two different experimental design (product array, combined array) approaches.

정보통신 기술의 발달과 전자상거래의 도래로 기업가치의 중심이 점차 고객으로 이동함에 따라 고객 관련 정보의 체계적인 통합 관리를 위한 CRM(Customer Relationship Management)의 구축이 급속도로 진행되고 있다. 특히 고객과의 접점 채널을 중심으로 e-CRM(Electronic-Customer Relationship Management) m-CRM(Mobile-Customer Relationship Management)과 같은 다양한 방법론이 제기되고있지만 고객과의 접근 방식 자체를 세부적으로 분석하고 최소화할 수 있는 방법의 제안은 현실적으로 부족하다고 볼 수 있다. 따라서 본 논문에서는 고객 접점 방법을 간소화시킬 수 있는 방법으로e-CARM(Electronic-Customer Approach Relationship Management)을 제안하였다. 또한 인중 메커니즘을 통한 e-CARM의 모델을 제시함으로써 제안된 방법론이 가질 수 있는 유용성을 보여 주었다.

This paper proposes a methodology for effectively analyzing a lot of design information written from various design viewpoints in an integrated s/w development environment. It provides a way of extracting the inherent role of the design contents, as well as easily accessing and understanding the other related ones on the web. For this aim, it defines a series of methods 1) to correctly capture relationships between the contents and the other related ones, 2) to translate them into a web object equipped with hypertext links corresponding the relationships, and to navigate all the related contents with the links. The suggested methodology have three advantages. First, it supplies ways to analyze new design contents invented from different points of view. Second, it can help user to easily access the related contents using hypertext links over WWW. Third, it provides an environment capable of effectively sharing and accessing design contents distributed on remote sites, thanks to the platform-independent property of the web.
