In the last decade many advanced home network services have been provided by construction industry, and many researches on the area have been carried out. One of the problems we are confronted with is that we do not have a standard classification scheme for home network services yet. In this paper a more stable classification scheme is suggested after comparative analysis of many different schemes in previous researches. More commonly highly attended service categories in the scheme is selected, and those are examined in terms of how commonly they are supplied by construction industry. In the later part of this paper the current home network building certification code is reviewed if the code complies with the highly attended categories in the classification scheme suggested in this paper. Some ideas to improve the current certification code is suggested by adding or optionally adding the highly attended categories.

CM services have continued to grow since the establishment of CM policies in 1997. Recently, strategies for overseas CM services have widely been discussed, because the CM services have expected synergy with planning, engineering, procurement and construction. However, there has been lack of quantitative and comprehensive research to investigate CM trends and prospects. In this sense, the purpose of this research is to statistically analyze total of 2,983 CM service contracts over the past 16 years (between 1997 and 2013) published in KISCON (Knowledge Information System of Construction Industry) in order to examine current status and future direction of CM industry.

The building HVAC systems have very different qualities of performance and durability with the superintendent's ability for management and maintenance. The poor management of these systems finally lead to the shortening of the life expectancy and result in the increase of operating costs and energy consumptions due to low efficiencies. So it is essential to try to develop ways to adequately maintain and to use the building facilities efficiently in order to preserve earth environment and the limited resource. In this study, the LCC based numerical calculation package will be developed for the efficient maintenance plan and the determination of the reasonable time of repair or replacement of equipments.

본 논문은 웹공간의 도서관 이용자들을 위한 하나의 서비스로서 디지털참고봉사를 효율적으로 운영하기 위한 공통선을 찾고자 하였다. 이를 위하여 웹에서 도서관의 참고봉사와 비슷한 기능을 수행하는 14개 벤처기업의 전문가서비스를 대상으로 사례조사를 하였다. 그 결과 각 인자별로 바람직한 요소를 발견하였지만 무엇보다 중요한 것은 참고봉사에 오랜 경험이 있는 사서로 하여금 디지털참고봉사를 전담하게 하는 것이 바람직하다.

웹 2.0의 등장과 함께 RESTful 웹 서비스의 활용이 전통적인 SOAP 기반 웹 서비스에 비해 크게 증가되고 있다. 최근 웹상에 이용 가능한 RESTful 웹 서비스들의 수가 급격하게 증가됨에 따라 사용자들이 적합한 웹 서비스를 찾는 것은 매우 중요한 이슈로 대두되었다. 그러나 기존의 키워드 기반 검색 방법은 나쁜 재현율과 나쁜 정확률 때문에 문제가 많다. 본 논문에서는 연관규칙 기반 클러스터링 기법에 패턴 기반 시맨틱 분석 기법을 추가한 하나의 새로운 시맨틱 온톨로지 구축 방법을 제안한다. 이를 통해 온톨로지를 자동 구축하여 시맨틱 정보의 주석처리 부담을 줄일 수 있고, 보다 효율적인 웹 서비스 검색을 지원한다. 본 논문에서 제안된 방법은 ProgrammableWeb 사이트로부터 168개의 RESTful 웹 서비스를 다운로드 받아 실험 분석을 수행한 결과, 기존의 키워드 기반 검색 방법에 비해 재현율과 정확률 두 측면에서 각각 35%, 18%의 성능 향상을 보였다.

XML Web Services are a distributed computing component which enables users to use services existing in remote places by using a standardized language called XML. Web Services were developed as the cooperation and business scales between companies as businesses had been widened due to the improvement of internet services. For this reason, enterprise sized Web Services are mainly used at present. But as the number of Internet users has been increased, they became in need of more diverse services, and providing individual Web Services are also being more emphasized. Therefore, an Embedded Web Server for personal Web Services for embedded systems such as cell phones had been implemented in this paper. This paper shows the possibility of building up a small, personal sized Web Services Server not the enterprise sized one by doing real implementation.

Size of building has a direct relationship with building cost, energy use and space maintenance cost. Therefore, minimizing building size during a project development is of paramount importance against such wastes. However, incautious reduction of building size may result in crowded space, and therefore harms the functionality despite the fact that building is supposed to satisfactorily support users' activity. A well-balanced design solution is, therefore, needed at an optimum level that minimizes building size in tandem with providing sufficient space to maintain functionality. For such design, architects and engineers need to be informed accurate and reliable space-use information. We present in this paper a conceptual framework of an agent-based space-use prediction simulation system that provides individual level space-use information over time in a building in consideration of project specific user information and activity schedules, space preference, ad beavioural rules. The information will accordingly assist architects and engineers to optimize space of the building as appropriate.

With developments of architectural and information technologies at the knowledge-information oriented society in the 21st century, there are the needs on intelligent buildings equipped with advanced systems to integrate both technologies. The intelligent building means a smart building which provides comfortable environments, realizes fast and speed information and telecommunication network services, and maximizes work productivities by adopting various systems suitable to uses, sizes, and functions of buildings. In order to meet these needs of the times, the domestic intelligent building certification system has been enforced in 2006. Recently, the intelligent building certification system was newly revised for revitalizing the spread of intelligent buildings. Thus, this paper investigates rating criteria and assessment standards of the new certification system focused on office building projects and suggests strategies for obtaining certifications by analyzing cases which were certified on the previous version of the system.

Objective: Companies want to expand their business by providing their services at other devices and new services based upon existing services. Therefore, they look for building brand identity by providing same experience throughout devices and services. Background: Many services are available to use at multiple devices including mobile phones, tablet, personal computers, and televisions, thanks to proliferation of n-screen and cloud technology. Method: It was discussed that consistency, which emphasizes the regularity and has been one of essential aspects of user interface design, seems not effective to be applied to n-screen services, owing to different screen size, input and output peripherals, usage environment and users' attitude. Results: A new definition of same experience among different devices and services, called coherence, was introduced and abstraction levels of user interfaces were proposed as the denominator of defining coherence. Then types of users' task knowledge at each abstraction level were discussed with examples. Conclusion: This paper concluded by discussing design requirements for designing coherent user interfaces among devices and services.

본 논문에서는 SOAP(Simple Object Access Protocol)기반 웹 서비스의 문제점인 확장성을 REST(REpresentational State Transfer)모델을 이용하여 해결한 RESTful SOAP 기반 웹 서비스 방식을 제안한다. 또한 웹 서비스 응용으로 전표 데이터 처리에 대한 웹 서비스를 SOAP 및 RESTful SOAP 방식으로 구현하여 서로의 장단점을 비교하고, 추후 웹 서비스 구축에 하나의 프로토타입으로 제시한다. REST는 분산 컴퓨팅 모델이며, 세계에서 가장 큰 분산 응용인 웹에서 사용하고 있는 웹 구조 스타일 모델이다. REST에서 리소스의 식별은 URI로, 상태는 상태가 표시된 문서(리소스)로써 HTTP를 통해 전달된다. 리소스의 내용은 XML로 기술하며, 리소스 탐색 및 참조에는 HTTP의 표준 메소드인 GET, PUT, POST, DELETE 등만을 이용하는 것으로 분산컴퓨팅을 모델링하고 있다. 본 논문의 결과는 전자 상거래시스템 구축의 주요 플랫폼인 웹 서비스의 효율적인 개발에 기여할 것으로 전망된다.
