On March 2011, an annual salary plan was applied to new faculty members in National Colleges and Universities. In 2015, all tenured faculty members will receive salaries based on annual performance evaluations. The efforts and accomplishments of faculty are normally assessed according to a standard formula of 40% teaching, 40% research and 20% service. In almost all colleges and universities, student course evaluations may be considered as the only measure of the perceived quality of the courses offered by the faculty member. The mandatory course evaluations are becoming prevalent in Korea. The results of course evaluations do not reflect the fairness and the appropriateness of the quality of the course taught by the faculty member and should not be considered under the teaching evaluation criteria.

Computing systems in the modern era are expanding rapidly to include mobile-based businesses that make us of the various convergence distributed business process. This has lead to growing interest in the field of mobile embedded software development methodology, which has in turn lead to the proliferation of the embedded mobility. The use of CBD (Component Based Development) provides reusability, maintainability and portability, all of which are very important and focus issues to the business process. It also comes with the inherent productivity, quality and reliability of CBD. To make efficient use of CBD, though, clarified interface definitions for component integration are necessary. These definitions should be made up of collaborative hierarchical and horizontal architecture layers. Successful definitions should apply an effective framework made up of the architecture and process. In this paper, we describe an interface specification for small grained mobile embedded components(MEC) for the mobile embedded domain to meet maximum user requirements. We build and deploy the reconfigurable design patterns and components (in business domain categories) to make a component hierarchy and business logics for mobile embedded software. Proposed components specification plays a major role in development of the software for handling inconsistency in existing specification. It also includes plenty of specification information, using semantics and modeling based mechanisms to support business processes. We propose a development model of mobile embedded software using CBD for very complex and dynamic mobile business. We can apply it in a plug and play manner to develop the software. We verify that our framework supports very good productivity, quality and maintainability to meet the user's requirements in mobile business.

Defects of dam body which can be induced in seepage or leakage procedure can directly affect dam safety. Therefore, a proper inspection method should be carried out in the first place to find out their positions and sizes, After that, some reinforcement works such as grouting and the corresponding assessment could be taken in a proper way. The dam(center core type earth dam) issued in this study has been in need for intensive diagnosis and reinforcement work, because a lot of slumps similar to cracks, seepage and some boggy area have been observed on the downstream slope. High resolution seismic reflection method was performed on the crest profile twice before and after grouting work(Aug. 2001 and Nov. 2004) aimed at the dam inspection and the assessment of grouting efficiency as well. To enhance the data resolution, P-beam energy radiation technique which can reduce the surface waves and hence to reinforce the reflection events was used. Strong reflection events were recognized in the stack section before grouting work, It seems that the events would be caused by e.g. horizontal cracks with a considerable aperture, Meanwhile such strong reflection events were not observed in the section after grouting. That is, the grouting work was dear able to reinforce the defects of dam body. Hence, the section showed an well arranged picture of dam inner structure. In this sense, seismic reflection method will be a desirable technique for dam inspection and for monitoring dam inner structure as well.

최근 국내기업들은 경영혁신 기법의 하나인 아웃소싱에 대한 검토 및 적용사례가 많아지고 있다. 아웃소싱이란 "정보시스템 기능의 일부 또는 전부를 외부업체에 위탁하는 과정"으로 정의된다. 그러나 이런 아웃소싱 결정은 최고 결정자(CEO) 의 소신이 없으면 어렵다. 따라서 본 연구에서는 회사의 최고경영자의 역할이 아웃소싱에 어떤 영향을 미치는지에 대하여 설문조사를 통하여 실증적인 분석을 하였다. 본 연구의 설문항목으로는 기업의내부적인 조직상, 관리상의 특성인 CEO의 컴퓨터 활용능력, CEO가 IS 조정(심의)위원회에서의 위치, 관리자(CIO) 와의 보고관계, IS 성과에 대해 아웃소싱의 활동범위 (7개)별로 구분하여 조사하였다. 아웃소싱 활동범위는 다시 S/W 활동(응용프로그래밍, S/W지원/교육훈련), H/W 활동(네트워크 관리, 중대형 컴퓨터 유지보수, 워크스테이션/PC 유지보수), 포괄적인 관리활동(시스템 통합, 설비관리)으로 구분하였다. 조사결과는 컴퓨터 활용능력이 높은 CEO가 아웃소싱을 많이 하였으며, 조정위원회에서 CEO가 활동적인 경우에는 S/W 분야에 아웃소싱이 많이 이루어졌지만, H/W, 포괄적 관리활동분야에서는 위원회 자체가 없는 경우에 아웃소싱이 많아졌다. 또한 CEO와 IS관리자(CIO)의 보고단계가 1단계 이상일 때는 모든 분야에서 아웃소싱이 많았으며, 산업계의 중간그룹에서 아웃소싱을 가장 많이 하는 것으로 조사되었다.것으로 조사되었다.

최근 RFID (Radio Frequency Identification)기술은 다양한 분야에서 관심을 받고 사용되고 있으며 RFID 리더의 종류도 매우 다양하다. 이러한 RFID 리더들을 지원하기 위해 RFID 미들웨어는 리더에서 지속적으로 발생하는 데이터를 수집, 제어, 관리하는 기능을 가지고 있으며 다양한 형태의 RFID 리더 인터페이스를 지원하여 이기종 RFID 리더와의 연동을 용이하게 한다. 현재 표준 규약에 따른 RFID 미들웨어들이 개발되고 있으며 RFID 표준 단체인 EPCglobal에서는 EPC (Electronic Product Code) 처리 시스템에서 RFID 태그를 인식한 리더가 애플리케이션 계층으로 데이터를 전달하는 역할을 하는 ALE (Application Level Events)라는 RFID 미들웨어를 제시하였다. 그러나 표준을 따르는 RFID 미들웨어는 그 자체가 복잡하고 부피가 크며 가격이 높기 때문에 이를 기반으로 한 시스템은 개발 속도가 늦어지고, 유지보수가 힘들어진다. 따라서 한 기업 내에서 사용되는 애플리케이션의 크기가 소규모 또는 중규모인 경우를 위해 보다 가벼운 RFID 미들웨어가 필요하다. 본 논문에서는 다양한 RFID 리더를 처리하기 위한 리더 매니저와 애플리케이션의 목적에 맞는 이벤트를 생성하는 쿼리 매니저를 가진 경량의 RFID 미들웨어를 개발하고자 한다. 리더 매니저는 RFID 리더를 관리하기 위한 추상 어댑터를 제공하고 리더 구성 XML 파일을 이용하여 RFID 리더를 관리한다. 쿼리 매니저는 질의 조건을 주기적으로 체크하는 스케줄러를 통해 RFID 이벤트를 관리한다. 본 경량적 RFID 미들웨어는 하드웨어의 투명성을 지원하며, 유지보수가 용이하고 유연성과 확장성을 제공하는 RFID 애플리케이션을 개발할 수 있도록 해준다.

Recently, damage of pavement represented by crack is depened by the increase of traffic demand up to ten million and wight, and interest about the efficient management of pavement is being increased gradually according to the growth of maintenance expense of road surface. In this study, the possibility of application for acquisition of crack information was tested by appling DCRP and digital image processing technique and measuring crack on road surface precisely. Based on this, objective and efficient road surface measurement was planned and done. Measuring crack width, acquire result of comparative high accuracy. So, it is considered that it can be utilized as plan draft data for deterioration estimation and repair reinforcement work of pavement.

Visual inspection works are very important part of facility maintenance and management life cycle as a step of creating base data for decision making and maintenance and repair. But currently, visual inspection works have been performed unefficiently and unreliably as works on hand, duplication of works, decisions of defect state, unutilization of inspection history, lack of professional and so on. In this research, we developed visual inspection system that processes inspection work efficiently and provides reliability of inspection output, as a target of bridges, tunnels, underground roadway on national road. We defined problems through visual inspection work analysis, examined the solutions and reflected to functional design of system. We will plan to utilize this system in HMCS(Highway Maintenance and Construction Service).
