제품-계열 방법은 소프트웨어 개발시 나오는 산출물들을 핵심자산으로 만들어 놓고, 이를 체계적으로 재사용할 수 있도록 지원하기 위한 프레임워크 역할을 한다. 그 초점은 소프트웨어 아키텍처나 상세설계 또는 코드에 맞추어져 있어서 임베디드 시스템 개발시 임베디드라는 특성화된 요구사항을 분석하고, 도출 하는데 미흡한 부분이 있다. 본 논문에서는 임베디드 시스템 개발시 요구분석 단계에 IDEF0 비즈니스 모델을 적용한 Feature 도출 및 분석 방법을 제안한다. 제안된 방법은 도메인 요구사항을 관리하는 측면에서 전체시스템에 대한 정확한 요구사항 도출과 분석이 가능하고, 도출된 Feature에 대한 공통성과 가변성을 식별 하는데 효율적이다.

In literature, it has been widely accepted that knowledge management (KM) success ratio in private companies depends on the corporate size and type of industries. However, there are few studies concerning the procedures about building knowledge management system in state-run corporations. Especially. as the Korean Government advocated the slogan saying. The Strong Nation with Knowledge and Information, the need to investigate the knowledge management case about state-run corporations instead of private companies becomes more urgent. In this respect, this paper is aimed at introducing how knowledge management system has been successfully incorporated in KAMCO, and summarizing several fact findings which are deemed noteworthy for other similar studies.

In this study, a novel method for monitoring road pavements using the Mobile Mapping System (MMS) and a deep learning crack detection system was presented. Furthermore, an optimal maintenance method through economic analysis was presented targeting the pavement section of Sejong City. As a result of monitoring the pavement conditions, it was confirmed that the pavement ratings were good in the order of national highways, municipal roads, and roads of provinces. In addition, economic analysis using the pavement deterioration model showed that micro-surfacing, one of the preventive maintenance methods, is the most economical in terms of maintenance costs and user benefits. The results of this study are expected to be used as fundamental reference for local governments' infrastructure management plans.

As the number of information asset and their vulnerabilities are increasing, it becomes more difficult for network security administrators to assess security vulnerability of their system and network. There are several researches for vulnerability analysis based on quantitative approach. However, most of them are based on experts' subjective evaluation or they require a lot of manual input for deriving quantitative assessment results. In this paper, we propose HRMS(Hacking and Response Measurement System) for enumerating attack path using automated vulnerability measurement automatically. HRMS can estimate exploitability of systems or applications based on their known vulnerability assessment metric, and enumerate attack path even though system, network and application's information are not fully given for vulnerability assessment. With this proposed method, system administrators can do proactive security vulnerability assessment.

Recently, many interests on the ubiquitous environment and the practical technologies associated with it have been significantly increasing along with the rapid development of wireless technologies. The development of the automated systems based on the ubiquitous environment is required as the concept of the term "ubiquitous" is integrated into the fields of existing IT. In this paper, we design and implement a power-saving management system using RFID/USN technologies. It efficiently manages the power consumption of the electronic machine such as electric lights, electric heaters, and air conditioners in a building. The proposed system controls the electronic machines and monitors their status by RFID and collects the real time information about the surroundings and power consumption of the electronic machines by USN. Especially, it analyzes the real time information and supports the intelligent scheduler with the best power-saving. Finally, this paper shows the difference between the proposed system and the existing systems and the reality of our system through the real time user interface about the power-saving management.

The purpose of this study is to develop an efficient BIM-based FM(Facility Management) system architecture to integrate the heterogeneous solution data related to FM. The heterogeneous solution data can be an FM system, asset management system, or facility sensor database systems, as well as files created by a modeler. In this study, we define the consideration for the external heterogeneous data integration related to BIM-based FM and propose the methodology. To implement it, trends in related studies were reviewed and general use cases of BIM-based FM were derived to develop the architecture for the integration between BIM and the heterogeneous solution data. The component architecture was designed to implement the use cases, and the schema was developed for the prototype by using the proposed architecture.

Voice of the customer(VOC) is a term used in business and information technology(IT) to describe the process of capturing a customer's requirements in enterprises or various organizations. Recently, in order to satisfy customer's needs, enterprises try to utilize VOC at recurrence prevention of problems and their improvement activities, planning and development of product/service by processing, storing, and analyzing VOC. Until now, VOC management systems are introduced around service industries such as hotel business and insurance/financial business, etc. This paper proposes an integrated management scheme of VOC which are captured by various communication channels and describes a case of implementing an integrated VOC management system on the basis of the proposed scheme for the large-scale manufacturing company. By the implemented system, VOC are stored and utilized as the important knowledge assets of enterprises.

Facility Management is the longest in the building of life cycle. Because it occupies more than 80% of cost, the phase of Facility Management has to be managed and has to be perceived as important as design and construction phase. The method to manage building more efficiently is the introduction of Facility Management System used by CAD and database. But information Requirement is now input by hand in the most Facility Management System. This study aims to analyze the example of applying BIM in the Korea or abroad and the errors of this were deducted by many phase. Lastly, the possible solution is suggested in order to be used in the Facility Management System. This study's benchmarking is COBIE which is developed by the COE(Corps of Engineers) and now popular in the world. The suggestion in this study is the method that I have already mentioned is helpful for a designer to do modeling when a designer uses BIM S/W(software). To be more specific, the method plays a side role in helping data input considering the phase of Facility Management.

National competence is based on the quality of university education, which is determined by the competitiveness of academia, research and information, IMD reported that Singapore, #2 country in national competence index, topped in quality of university education. Meanwhile Korea's current national knowledge infrastructure project lacks comprehensive coordination at a governmental level and has been conducted in a rather sporadic manner, without any consideration on the overall analysis of knowledge information resources. Consequently, a disproportionate amount of attention was devoted to collecting general information resources, while neglecting rare, hard-to-collect sources with historic, academic, and/or cultural values. This study proposes to build an academic resource management system to fully supervise academic resources at least, among national knowledge information resources which is a national asset, and also to allocate budget and cultivate new information building projects based on overall analysis on academic resources. In other words, there is a need for a management system to implement efficient linkage, distribution and utilization of academic resources and, to that end, we need to build an academic resource management system at a national level, maximizing the benefits from the knowledge society that we live in.
