This paper presents a GIS-based method of spatial analysis that can be applied to the line determination in traffic infrastructure project . It is based on the spatial analysis of the sensitivity or suitability of areas relating to the integration of new infrastructure routes, carefully considering the requirement of intervention optimizing . It makes the comparison of alternatives and a final selection of a"best route " easier, offers new possibilities and simplifies and accelerates the whole process of line determination. The developed method for route-alignment is tried out by an example project for road planing in Germany. It point out that during the line determination all aspects can be equivalently and adequately evaluated. So this method is well suited as a new tool within a line determination procedure and can bring enormous advantages in the planning process of traffic infrastructure projects. projects.

소프트웨어 제품의 품질을 보장하기 위해서는 제품을 개발하는 단계에 미리 결함율을 예측하여 원하는 수준의 품질을 확보하는 것이 중요하다. 결함은 사용자의 요구사항이 제품으로 구현되고 기능에 대한 테스트가 수행되는 단계에 가장 객관적이며 정량적으로 관리될 수 있다. 따라서 본 논문에서는 통합테스트에 대한 계획을 수립하는 단계에 제품에 대한 결함율을 미리 예측하여 제품 결함율이 조직의 관리범위에 들어올 수 있도록 통제하는 결함예측모델을 제안한다. 조직의 제품 결함율 베이스라인을 설정하고 통합테스트 결함율에 영향을 미치는 변수들과의 회귀분석을 통해 통합테스트 결함예측모형을 구축한다. 또한 제품 결함율에 영향을 미치는 변수들과의 회귀분석을 통해 제품 결함예측모형을 구축하고 결함예측모형을 활용해 제품 결함율을 분석 및 통제한다. 본 논문에서 제안한 결함예측모델은 실제 프로젝트에 적용하여 실효성을 검증하였으며 제품이 완성되기 전에 결함율을 예측하여 통제할 수 있게 함으로써 소프트웨어 품질을 향상한다.

Effectiveness of Just in time managing system can be obtained by removing unexpected lead-time and maintaining consistency on the physical transportation of construction resource. Construction resource management is essential on checking on load data from production of shop to field, and it is based on building resource life cycle information. In this study, production, transportation, and assembly disciplines of concrete construction should real time communications exchanging information related to shop-field with each other, Establishing information support system is an important initial step for promoting active cooperations among these resource life cycle on data flow. To achieve this, on suitable using management point, we suggest a concrete construction control model.

It has recently been combined with advanced technologies such as AR and VR, and its application range is expanding to various forms of smart signage. However, until now, digital signage service that reaches us is installed in many floating populations such as bus stops, elevators, and banks and is used in the form of providing news, weather, and advertisements. In addition, large companies, government offices, and outdoor advertising companies occupy the market. The use of such services in small and medium-sized businesses and small retail stores is costly and expensive to manage. Also, it is difficult to generalize the market because services and solutions are being deployed in the market in the form of top-down. Therefore, in this paper, we proposed a digital signage system for transmitting a remote video advertisement that uses a show window in front of the store as a beam project screen for small retail stores, and can remotely set and manage and update it in OSGi service platform.

There is increasing demand for enterprise smartwork system by a mobile device increases in these days. Therefore, it has been suggested in the technical platform of smartwork system. But,the research of the changeable smartwork system for quick and immediate correspondence of rapidly changing business affairs is insufficient. In this paper, we propose an adaptable mobile service architecture that can be based on the construction of flexible mobile smartwork system. This adaptable mobile service architecture is possible to dynamic service connecting the adaptable service in an existing smartwork system, and the core elements of the adaptable mobile service architecture propose 'Adaptable Service Manager', 'HotSpot', and 'Configurator'. We propose the dyanmic service processs that based on These core elements. Also, we verify the feasibility through case study that develop the project management mobile service that is usable in business of enterprise. Thus, this research provides the adaptable mobile service architecture that can provide the dynamic mobile service beyond the static mobile service of the existing smartwork system for the various change business of enterprise.

Recently, 3D laser scanning technology, which can collect accurate and quick information on phenomena, has been attracting attention among smart construction technologies. 3D laser scanning technology can obtain information most similar to reality at construction sites. In this study, we would like to apply a new member identification method to an actual building and present the possibility of applying point cloud data, which can be collected using 3D laser scanning technology, to measuring progress at construction sites. In order to carry out the research, we collected location information for component identification from BIM, set a recognition margin for the collected location information, and proceeded to identify the components that make up the building from point cloud data. Research results We confirmed that the columns, beams, walls, and slabs that make up a building can be identified from point cloud data. The identification results can be used to confirm all the parts that have been completed in the actual building, and can be used in conjunction with the unit price of each part in the project BOQ for prefabricated calculations. In addition, the point cloud data obtained through research can be used as accurate data for quality control monitoring of construction sites and building maintenance management. The research results can contribute to improving the timeliness and accuracy of construction information used in future project applications.

Ran Gang is a huge, attractive river which meanders through Seoul, the capital of South Korea. However, during the modernization of Seoul, the river gradually lost its natural beauty and healthy condition. Han Gang Renaissance is a project to upgrade the look of the Seoul waterfront, by overcoming this disaster and reorganizing the surroundings of Han Gang. This research articulates the design strategies and description of the prizewinning work of the International Design Competition for Yeouido Riverside Park that was linked to the Han Gang Renaissance Project. There are three key points that basically speak to the identity of the new waterfront, Yeouido Riverside Park. First, the current day Yeouido was recreated as an artificial island through the rapid expansion of the city and the initiation of the shore protection works. However, because it is the only island still remaining that shows the history of Han Gang, the park was designed to be the place which preserves the lyric of sand island and the emotional memory of riverside. Secondly, among the six districts of the Han Gang Renaissance Project, the two districts that are facing each other, Yongsan and Yeouido, are the central areas promoting international finance and business. Despite Yongsan's complete urban image, the exquisite harmony of pastoral scenes and skyscrapers of the Yeouido waterfront is presented to develop an active mutual relation with Yongsan. Lastly, this design scheme re-establishes the relationship between this competition's site, Yeouido Riverside Park, and a neighboring site, Yeouido Park.

Recently, BIM(Building Information Modeling),which has been an issue in construction work, has been focused on as a new alternative of building industry for way out of crisis by slowing down and decreasing of orders in construction industry. Research for introducing BIM to the architectural field is already proceeding actively at home and abroad. However, civil engineering is so nonrecurring, horizontal, and different from regular construction works that it a large amount of information occurs because of wide range of project, which causes construction firms and design engineers to have some questions whether their initial investment cost would work or not and feel uncomfortable with the cost. In this study, technology level in engineering firms were surveyed for adapting BIM to domestic civil engineering. Development direction of BIM standard information model was drawn through awareness change analysis of BIM in civil engineering, as well. Deduced development direction is composed of guide development, system development, deliverable check and international standard proposal. The outcome will be employed as preliminary data for the study on development of infrastructure BIM standard and deliverable check system in civil engineering.
