The software development methodology has not caught up with the rapid change of information technology. Most of the software development projects use structural methodology or information engineering methodology. If established software development methodologies don't reflect technologies applied to the project, the project may be performed ineffectively. This paper describes a model in which we can apply a new information technology to an already existed structural methodology or information engineering methodology. This model uses the technique of the divide and conquer that software development life cycle is divided into phases, each phase is divided into viewpoint- areas and the software development processes of a new information technology are applied to each small area. By using the design phase this paper shows application example, in which I applied web-based development processes to CS@RoadMap Methodology of KCC Information & Communication, a system provider in Korea. The CS@RoadMap Methodology reflecting the Web technology, Web@RoadMap Methodology, has been applied to the public-domain projects.

As the online education market expands, educational contents with various presentation methods are being developed and released. In addition, it is imperative to develop content that reflects the usability and user environment of users who use this educational content. However, for qualitative growth of contents that will support quantitative expansion of markets, existing model analysis methods are urgently needed at a time when development direction of newly developed contents is secured. In this process of content development, a typical model for setting development goals is needed, as the rules of the prototype affect the entire development process and the final development outcome. It can also provide a positive benefit that screens the issue of performance dualization between processes due to the absence of communication between a single entity or between a number of entities. In the case of AR-based educational content which is effective to secure data necessary for development by securing samples of similar categories because there are not enough ready-made samples released. Therefore, a big data statistical analysis service is needed that can easily collect data and make decisions using big data. In this paper, we would like to design analysis services that enable the selection and detection of intuitive multidimensional factors and attributes, and propose big data-based statistical analysis services that can assist cooperative activities within an organization or among many companies.

Team collaboration is becoming commonplace and it is spotlighted in agile software development projects as well. More efficient teamwork in terms of effective team operation and project performance is very important. Heuristic software development staffing method has been used, but algorithm approach is needed to compensate for it. In this paper, we propose a mathematical approaches for staffing developers in teamwork-based software development projects. This consist of six process, and activities in each processor is defined as a mathematical function placement, and functional deployment matrix is used. A case study is presented in order to prove the usefulness of this approach. This paper is a significant research because a mathematical approach of work assignment is developed for human resources by quantitative logic and it deviate from intuitive or heuristic methods used previously.

Conceptual Model of the Mission Spaces(CMMS) is a first abstraction model of the military real world and serves as a knowledge(mission spaces) reference models for development, interoperability and reusability of defense modeling and simulation(M&S) systems, by capturing basic information about entities involved in any mission and their key actions and interactions. Therefore, the completeness of CMMS is the key to success for the quality of M&S systems based on it. To improve quality and credibility of CMMS, the Verification, Validation and Accreditation(VV&A) processes of CMMS is very important. This paper briefly describes the K-CMMS(Korean Conceptual Model of Mission Space) and the VV&A process.

The service industry is becoming greater importance in the current economy. The service quality has become an important competitive factor in service industry. Until now, 6 sigma method has well accomplished in manufacturing industry. 6 sigma method has been applied to the service industry to improve service quality, but it has not been reported that 6 sigma method is a successful method for service industry to improve service quality. In this paper, we suggest a MAVIC model to improve service quality. It is a model which is combined with advantages of a SERVQUAL model and 6 sigma method. We has proved its effect with applying a MAVIC model to real service techniques.

미래유망기술정보는 차세대 제품을 개발하려는 기업뿐만 아니라 R&D를 수행하는 연구자에게도 중요한 정보이다. 그런데, 이런 중요성에도 불구하고 국내외 많은 기관에서 발굴은 하지만 그 결과를 평가하는 사례는 드문 게 사실이다. 본 고에서는 체계적이고, 효율적인 미래유망기술정보의 후행평가 모델을 정립하기 위하여 국내외 사례를 조사, 시사점을 도출하였으며, 이를 기반으로 미래유망기술 후행평가 프로세스를 제안하였다.

In the domestic construction field, BIM and 3D scanning technology are combined to perform reverse engineering. It is necessary to develop guidelines or processes for domestic situations through 3D scenario investigation and reverse engineering projects using BIM. Using the case of actual construction service that performed reverse engineering, we analyze the areas that need to be reinforced compared to the existing advanced cases when creating guidelines. It is recommended to encourage the convergence between 3D scanning and BIM, and to define the requirements and levels of the BIM model in the procedure.

To fully utilize scarce spectrum resource, it's necessary to develop and evaluate promising business models prior to making technology R&D plan and industrial promotion policy. The purpose of this paper is to design potential business models, evaluate the propriety of commercializing the models, and discuss promotion policies after exploring promising sectors consuming spectrum resources. The research is based on TV white space, which is vacant TV channels in region or time domain and considered as core spectrum resource along with digital terrestrial television switchover. As the result, four kinds of business models were derived, including broadcasting and telecommunication types. Each model was discussed from four standpoints: customer value proposition, profit formula, key resources, and key processes, and the propriety for commercialization was evaluated by three dimensions: technological evaluations, business-oriented evaluations, and user-oriented evaluations. The promotion policies of government and market participants for the activation of TV White space-based business models were discussed as well.

The high portability and mobility of mobile devices have given rise to critical concerns with regard to mobile situation-aware services that utilize user situation information in the mobile domain. Mobile situation-aware services for mobile devices are provided by collecting and analyzing data, from which the user situation is inferred through an inference system. However, the high mobility of the mobile domain has made it difficult to infer the required results. In addition, previous studies have not identified a systematic approach to modifying and adapting. In this paper, we propose a systematic feedback process model based on software cybernetics in order to address the abovementioned problems. Further, we propose a MADA(Monitoring, Analysis, Determinating, Adaptation) framework for the feedback process model. Thus, the proposed approach supports the development of self-adaptive mobile situation-aware services that can infer appropriate results and manage the inferred results systematically.

One of the reasons that debugging distributed programs is much more difficult than sequential programs is the communication among processes. Even though there are many debuggers constructed on distributed system environment, no available debugger provides an efficient way to debug communication events.. In this paper, we show the way to debug RPC communication, which is regarded as one of the most popular communication protocol in distributed system development. This paper presents the implementation of the RPC event trace function based on the RPC event model, which is proposed to accommodate communication events into debugging objects. Analyzing conventional RPC protocols, we formalized library function calls as corresponding actions to sending and receiving of messages. B recognizing the locations of library calls the debugger can detect all occurrences of communication events, This RPC event trace function is implemented on the on-line distributed debugger UniVIEW system.
