As the information technology advances and the number of internet users increase, the electronic commerce has been discussed actively in the academic and industrial circles. Though the reference model is important as a guide to the study on electronic commerce at this time, current studies on the reference model are inclined to emphasize on the specified area, not on overall area. In this respect, this paper aims to provide the synthetic reference model - named the ECGR model(Electronic Commerce Generic Reference model) - and its application plans. First, for these purposes, several frameworks and reference models of electronic commerce are compared and analyzed from the various viewpoints. Second, several factors for the development of the reference model are proposed. Finally, the ECGR model is developed and its application plans are suggested. The ECGR model provides a conceptual and analytical apparatus to interpret the profound understanding of electronic commerce and presents the fundamental framework related to the electronic commerce projects. According to the expansion of electronic commerce and the development of related information technology, the ECGR model must be modified.

The objectives of this study were to review studies on the community attachment and to identify it's related variables. Community attachment variables were divided into linear development model variables and system model variables. The theoretical base for linear development model originated from Ferdinand Toennies(1957) and system model was from Kasarda and Janowitz(1974). Linear development model variables were population size and density. And system model variables were age, education, income, number of children, marital status, length of residence, sex, and job. Recent studies on the community attachment were being carried out through system model than linear development model.

소프트웨어 개발 초기에 개발비용, 소요인력과 기간을 추정하는 것은 소프트웨어공학 분야에서 어렵고도 중요한 문제이다. 이 정보들은 소프트웨어 요구사항 명세서로부터 측정된 소프트웨어 규모인 기능점수를 이용하여 추정한다. 측정된 소프트웨어 규모를 개발하기 위해서는 개발팀을 몇 명으로 구성할 것인가가 문제로 제기된다. 본 논문은 소프트웨어 개발팀의 규모를 추정할 수 있는 모델을 제시한다. 모델을 유도하기 위해 301개 소프트웨어 프로젝트들이 사용되었다. 먼저, 통계적 알고리즘 모델인 회귀모델을 연구하였다. 다양한 데이타 변환과 회귀분석 결과 좋은 성능의 모델을 얻지 못하였다. 따라서, 비알고리즘 모델인 RBF망을 적용하여 잔차가 랜덤하게 분포하고 우수한 성능을 가진 모델을 제안하였다. 본 모델은 소프트웨어 개발에 필요한 개발팀 규모에 대한 기준을 제공함으로써 인력관리 정보로 활용할 수 있다.

최근 XML표준기술을 활용한 웹서비스는 기업내 및 기업간의 정보시스템을 통합하는데 발생되는 문제점을 해결해 주는 차세대 e-비즈니스의 기반으로 급부상하고 있다. 정보기술이 지속적으로 변화하기 때문에 특정 기술에 기반한 시스템을 정보 기술 변화에 맞게 통합, 변화, 유지하는 것은 지속적인 문제로 고려되고 있다. 이러한 문제점을 해결하기 위해 OMG는 MDA(Model Driven Architecture)라는 새로운 소프트웨어 아키텍처를 제시하였다. MDA는 기존의 개발 절차에서 분석모델인 플랫폼 독립적인 모델(PIM, Platform Independent Model)을 구축하고 이를 기반으로 설계모델인 플랫폼 종속적인 모델(PSM, Platform Specific Model)로 자동 변환하는 프로세스를 가진다. 이러한 자동 변환을 통해 여러 플랫폼을 쉽게 지원하고 개발자의 입장에서는 코드 작성에 소요되는 시간을 줄일 수 있으며 개발 프로세스의 측면에서도 품질관리를 수월하게 할 수 있다. 이 MDA의 개발 프로세스를 웹서비스개발 프로세스에 적용하면 MDA의 PIM에서 목표플랫폼으로 웹서비스를 선택하고 웹서비스 모델인 WSDL로 PSM을 표현할 수 있다. 본 논문에서는 웹서비스 공급자와 요청자가 웹서비스를 개발하거나 통합할때의 절차를 분류하여 웹서비스 개발 프로세스유형을 만들고 웹서비스 개발시 MDA개발 프로세스를 적용하여 웹서비스공급자와 요청자가 참조가능한 새로운 웹서비스 개발 프로세스를 제안한다.

The purpose of this study is to develop the growth prediction model that can predict growth and development information influencing on the production of citrus fruits. The growth model was developed to predict the floral leaf ratio, number of fruit sets, fruit width, and overweight fruits depending on the main period of growth and development by considering the weather factors because the fruit production is influenced by weather depending on the growth and development period. To predict the outdoor-grown citrus fruit production, the investigation result for the standard farms is used as the basic data; in this study, we also understood that the influence of weather factors on the citrus fruit production based on the data from 2004 to 2013 of the outdoor-grown citrus fruit observation report in which the standard farms were targeted by the Agricultural Research Service and suggested the growth and development information prediction model with the weather information as an independent variable to build the observation model. The growth and development model for outdoor-grown citrus fruits was assumed by using the Ordinary Least Square method (OLS), and the developed growth prediction model can make a prediction in advance with the weather factors prior to the observation investigation for the citrus fruit production. To predict the growth and development information of the production of citrus fruits having a great ripple effect as a representative crop in Jeju agriculture, the prediction result regarding the production applying the weather factors depending on growth and development period could be applied usefully.

The purpose of this study is to suggest the analytical framework for a spatial structure of a tourism destination master plan by the two types of the tourism development models: Tourist attraction System Model and Tourism Destination Region Design Model. The resort development plan is introduced as a planning tool for regenerating the eastern Pusan regions, but the economic and environmental impacts and the sociocultural dilemma accompanied by the development should be fully considered before launching the business. The development plan announced currently is traced and examined in comparison with the upper-leveled and related plans. The Tourist Attraction System Model based on the systems theory is applied to the designated regions. The Tourism Destination Region Design Model then is applied for analyzing the components of each region on the master plan. The results of the findings suggest that the tourism destination plan is basically different from a general master plan on the physical comprehensive plan, the destination is recognized as a subsystem of the whole tourism system, and thus tourism destination plan is considered as a spatial arrangement of tourism facilities and the inter- and intra-circulation.

Currently, our society is showing many changes due to the influence of information and communication technology (ICT). At the center of these information and communication technologies are software, intelligence, and sensing technologies. The software-related industry is steadily developing due to various software development policies implemented by the government and related organizations. Software development is desirable, but on the other hand, some negative aspects are also appearing. In this study, we proposed an objective way to infer the progress of software development for reasonable resolution of cases when a dispute related to the progress of development occurred during the software development process. The proposed solution was based on the waterfall model. The outputs generated in each process of the waterfall model are contents excluded from subjectivity. Therefore, it can be used as an objective method for calculating software development progress.

Prior research in R8ED innovation in Korea has been centered around the 'three-stage development model,' which hypothesizes that the Korean innovation process goes from the introduction (of foreign technology) stage, through assimilation stage to the final modification stage. As Korean economy shifts from traditional industry-led development to innovation-centric development, such an approach loses sight of the whole picture. The current study argues that a new framework is required for adequate analysis on newly arising innovative patterns in Korea, emphasizing source technology development and technology leader strategy. For this purpose, we propose the 'Jigsaw Puzzle Model' of technology development, which is then verified by an in-depth analysis on the innovation processes of 3 representative IT products of Korea, DRAM, TH LCD, and CDMA. The model suggests that Korean innovation model is a dynamic, efficient amalgamation of foreign-acquired and dependent technologies, based on internally accumulated technological resources. The model explains better how Korean firms are achieving a rapid catch-up of technological gaps with advanced nations and are able to transfer from the technology follower to the leader position.

An embedded system is a computer system designed to perform one or a few dedicated functions often with real-time computing constraints. A traditional design process of embedded systems is the development of document-centric approach, and it is difficult to develop an embedded system efficiently because communication between teams or steps is not smooth. So the Model Based Design Process are applied to the development of embedded systems. This paper will compare the Model Based Design Process and the traditional design process, and introduce example of development of vehicle device applied the Model Based Design Process.
