Subcontracting of construction is essential to carry out public construction projects. Subcontractor of the construction work shall enter into a contract with the original contractor without directly entering into a contract with the owner. Subcontracts are therefore greatly affected by the original contract with the owner. To protect subcontractors, the Fair Trade Act is enacted and the construction company's standard subcontracting contract is in operation. However, subcontracts are not properly reflected in the Government contract system, which deals with the relationships between the owner and the original contractor. In particular, the subcontractor may complain of difficulties at the public construction site as such procedures are not properly reflected in the construction work standard subcontract, although various procedures shall be carried out depending on the amount when change order occurs in subcontracts. Thus, the direction of improvement of subcontracting systems was proposed in the case of change order at public construction project sites as follows: First, the rights of subcontractors should be strengthened. Second, in order to resolve the information non-identity, subcontractors should have access to information related to subcontracts. Third, the status of subcontractor shall be guaranteed by reflecting the characteristics of the subcontract when the original contract for public works is concluded. Fourth, the dispute settlement method should be prioritized over litigation in order to fair subcontracting.

Currently, suggesting directions for strengthening publicity of social services is thinking in the direction of each person's advantage from the stakeholder's perspective. The position of the service provider and the position of the user shows different opinions on the definition and evaluation of publicity of the city or province as the management entity. Therefore, this study combines opinions on publicity focusing on community service, derives consensus on the definition and evaluation of publicity, and evaluates different indicators or factors that cannot be quantified at the same time. The goal is to solve the problem of publicity by applying the Analytic Hierarchy Process(AHP) as a possible technique. In addition, in order to achieve the research objectives according to the designed frame, an empirical study was conducted by conducting a pairwise comparison questionnaire for experts and users. Through the AHP evaluation model" developed in this study, as a result of measuring the relative satisfaction of major factors, service utilization rate (0.470), facility management (0.210), and other project implementations (0.073) appeared in order. Here, the service utilization rate was evaluated as the most important.

Recently, mandatory BIM design has been enforced in the civil engineering field, focusing on public projects, and inducement measures to actively participate in BIM by participating subjects are required. The BIM ordering documents must reflect the characteristics of the BIM project, current construction standards and laws, and environmental conditions of domestic participants. In this study, we analyze the ordering documents used in domestic and overseas civil engineering BIM projects to determine whether they meet the purpose of BIM. In the future, items that consider the existing heterogeneous data linkage and compatibility, the connectivity with the current construction guidelines and laws, the cost of the designer and the input personnel are prepared for the part that does not meet the BIM purpose. Furthermore, the written order documents are verified through interviews with experts who have experience in BIM projects. Through the results of this study, I would like to propose a consultation system strategy to prepare and present items according to the purpose and type of project by client.

The rough design information is only available from BIM(Building Information Model) based schematic design. So, it is difficult to obtain sufficient information for generating BOQ. Like 2D design, there are some problems that the results are depend on what the choice of cost estimator. However, the most research of BIM based cost estimation are focus on quantity takeoff, the consideration of work item for generating BOQ is insufficient. Therefore, this paper present automatic inference process of work items in a BOQ using ontology. The proposed process and ontology is validated through applying tiling construction. If the proposed process is utilized, it is expected the basis of developing generation method for consistent BOQ by resolving intervention of cost estimator's arbitrary decision.

컴퓨터는 인간의 모든 꿈과 희망을 실현시켜 줄 수 있는 마법상자는 아니다. 정보화 시대라고 일컫는 현재, 정보의 가치를 더해주는 컴퓨터의 중요성은 날로 커지고 있는 반면 인간의 존엄성은 경시되고 있다. 많은 사람들은 요즘 사회가 커다란 도덕적 위기에 빠졌다고 걱정하지만 컴퓨터 사용과 관련된 윤리적 문제에 대해서는 심각하게 느끼지 못하고 있는 것 같다. 정보통신 기술의 발달에 따라 새로운 교육의 필요성이 대두되고 있다. 기존의 전통적인 교육방식에서 사이버 윤리 교육은 교과서 중심의 단편적인 교육이었기 때문에 학습자의 흥미를 유발하지 못하였으며, 교육자와 학습자의 상호작용이 부족하여 사이버 윤리 교육의 효과가 미흡하였다. 정보통신 기술의 발달에 따라 새로운 교육의 필요성이 대두되고 있다. 기존의 전통적인 교육방식에서 사이버 윤리 교육은 교과서 중심의 단편적인 교육이었기 때문에 학습자의 흥미를 유발하지 못하였으며, 교육자와 학습자의 상호작용이 부족하여 사이버 윤리 교육의 효과가 미흡하였다. 이런 관점에서 본 논문은 정보통신 시대가 수반하고 있는 사회적 영향력과 윤리적 이슈들에 대하여 좀더 교육적인 측면으로 접근해 윤리교육의 현황과 문제점, 그리고 체계적인 확산방안에 대해 살펴보았다. 본 논문에서는 사이버공간에서 윤리 교육을 받는 청소년들을 중심으로 그들에게 새로운 윤리교육의 한 형태인 사이버공간에서 관련된 문제들을 교육적인 측면으로 해결할 수 있는 방안을 제시하고자 한다. 그러나, 무엇보다 우리가 명심해야 할 것은 인간의 존엄성은 그 어떤 이유를 막론하고 존중되어야 한다는 사실이다. 검증되지 않은 스토리 보드에 의한 저작 단계로 바로 돌입하고 있는 것이 한국의 실정이라 하겠다. 따라서 본 프로젝트에 의해 개발 된 교수 설계 도구는 교육/학습 컨텐츠의 품질 보증을 위한 방법론인 교육 공학의 체제적 교수 설계 이론 Model (Instructional System Design Model), 특히 그 중에서도 이 분야의 사실상의 표준 이론(de facto standard)인 Dick & Carey 교수와 Gagne 교수의 인지주의 ISD Model을 기반으로 정교한 교수 설계와 코스 맵 설계를 가능하게 함으로써 학습 컨텐츠의 품질 보증 활동을 지원 할 수 있는 도구로 개발하였다. 특히 Linux 기반에서 PHP로 개발 함으로써 Platform에 구애받지 않은 사용 환경을 구현 하였으며 향후 많은 e-Learning Platform에 교수 설계 모듈로 장착 함으로써 기존의 e-Learning Platform들의 가치를 높일 수 있는 계기가 될 것으로 생각한다.실징후를 파악하는데 그치지 않고 부실의 원인을 파악하고 이에 대한 대응 전략을 수립하며 그 결과를 측정하는데 활용될 수도 있다. 따라서 본 연구에서는 기업의 부도예측 정보 중 현금흐름정보를 통하여 '인터넷기업의 미래 현금흐름측정, 부도예측신호효과, 부실원인파악, 비즈니스 모델의 성격규정 등을 할 수 있는가'를 검증하려고 한다. 협력체계 확립, ${\circled}3$ 전문인력 확보 및 인력구성 조정, 그리고 ${\circled}4$ 방문보건사업의 강화 등이다., 대사(代謝)와 관계(

Naval Ships have a number of requirements related to performance. Naval ship acquisition takes a long time from initial planning to delivery, and various products such as drawings and reports are created. In complex systems, such as naval ships, it is difficult to maintain the required traceability through these outputs. The basic design of the ship is an important step to determine the specifications, performance, and equipment of the ship. It is necessary to apply the systematic requirements management process. The basic design manages the requirements in accordance with the systems engineering-based technical review process, but the actual system architecture design process is not presented. The traceability between the requirements and the functional and physical architectures of components is unclear. This paper examined how to design the system architecture required for specification and system design, and the design results were verified using SE-based technical review process for requirements management. A step-by-step process for designing a submarine system architecture is presented and verified using the SE technical review. This facilitates the specification of the requirements and system architecture design, and supports traceability management and verification of the requirements. The proposed process can be applied in various ships including submarines.

In this paper, we present, an indstrial RFID layered microstrip patch antenna is designed using an inset feed method in order to improve recognition rates in a long distance as tags are attached to metal object by improving a problem of feeding power in fabricating metal tags and reducing effects of metallic object. The inset feed shows a distinctive characteristic that has no separation between emitters and feed lines differing from a structure with the conventional inductive coupling feed. This structure makes possible to produce a type that presents a low antenna height and enables impedance coupling for tag chips. Although it shows a difficulty in the impedance coupling due to increases in the parasite capacitance between a ground plane and an emitter in an antenna according to decreases in the height of a tag antenna, it may become a merit in designing the tag antenna because the antenna impedance can be determined as an inductive manner if a shorted structure is used for feeding power. Therefore, in this paper the microstrip patch antenna is designed as a modified type and applies the inset feed in order to reduce effects of metallic objects where the antenna is be attached. Also, the antenna uses a multi-layer structure that includes a metal plate between radiator and ground instead of using a single layer.

In my study, I analysed and criticised the change of applied works based on a design drawing of a private forest road in Chungchengnam province from 1990 to 2003. The aim of this study is to obtain the fundamental resources for establishment the green forest road which is environment friendly. Working expenses of forest road was gradually increased by a business year. In particular, the working expenses dramatically increased in 1999-2000. In change rate of cost of construction by works, earth work rate of the cost of constructions was declined: from 25.4% in 1990-1999, to 18.5% in 2000-2003. However, the total cost of the construction of slope protection work and structural work increased. Nevertheless the rate of the cost of constructions are not increased where as the earth work rate of the cost of constructions were reduced. The rate of the price construction materials and the cost of construction was the main causes which was led by the extension of the standard requirement of applied work and the increase of the materials of applied work. In other word, materials of structural work and slope protection work increased. If the increase of the cost of construction has seem through the increase of contractual materials and extension of the standard requirement would led to weak competitiveness of forest road. Therefore, diverse method of constructions need to apply and a new method should be developed.
