Recently, there has been an increase in the number of web-based three-dimensional (3D) printing-related service platforms, which allow consumers to collect 3D modeling data, make requests for production, and receive goods through a distribution service using the service platform. The application of 3D printing technology has been expanded to the construction field, yet no guidelines for the related service platform or operation examples can be found. Therefore, the functions of 10 web-based 3D printing service platforms actively used in other industries were investigated and analyzed in this study, and the analysis results were used as a guideline to develop a 3D printing service platform for the construction industry. In addition, the design, construction and distribution services to be equipped with the construction 3D printing service integration platform were presented by creating the driving scenario of the platform. As 3D printing technology develops, the overall construction and architectural paradigms for design, construction and distribution will change. To prepare for such changes and to pioneer the digital construction market in the future, the role of the 3D printing service platform is expected to increase continually.

The service quality with the various building equipments tends to depend on the individual superintendent's capability and efforts generally and this often lead to poor maintenances and managements of them. N-BMS(Networked Building Management System), proposed in this study, is a new type of building management method, which links principal equipments within many buildings into a communication network and carries out several significant missions such as fault detection, deterioration diagnosis and control the equipments and so on, as well as monitoring which is the main and unique purpose of the conventional BMS. How to construct the N-BMS was considered to keep performance of equipments high and thus to save energy and resource. LCC(Life Cycle Cost) based analysis was also performed in order to verify the effects of some maintenance and management works for the building HVAC systems.

The purpose of this study is for the fundamental understandings about building morphological parameters and aerodynamic roughness parameters of Seoul, Korea using the detailed urban geographic information datasets. Applied roughness parameter calculations are based on a digital map of buildings with lot area polygons. The quality of the developed roughness length ($z_0$) of Seoul was evaluated with densely installed 107 automatic weather stations. The correlation coefficient results between averaged wind speeds of AWS data and averaged $z_0$ is -0.303 in night and -0.398 in day (200 m radii circles case). Further $z_0$ enhancement should follow by considering other surface features such as high tree and orography of Seoul. However, this study would meet the needs to for local- or meso-scale meteorological modeling applications of Seoul. However, further studies would require for enhancing the $z_0$ applications of Seoul.

In recent years, BIM services have been used in many construction projects. However, they are raising the question that there are many differences between what was initially proposed and what was actually done. In the IT sector, a method called as SLA is used to perform an assessment of the services delivered to the IT service project. In this respect, this study intends to introduce this method into building construction projects to use BIM in order to propose evaluation criteria and the evaluation process for SLA-based BIM service. The BIM service assessment process and criteria presented are judged to help introduce consistent and systematic BIM services in construction projects.

Large-scale urban developments with increasing population and expansion of industrial facilities have destroyed the ecosystem. Consequently, the importance of vertical farm as a form of urban agriculture is increasing. However, such problems of vertical farms as economy and lack of awareness of residents are being raised. Firstly, this study derived types of vertical farm that are applicable to residential spaces through an examination of vertical farm buildings, and then inferred assessment items for a questionnaire survey for the development of u-services. Secondly, based on the issues deduced from the survey, u-services needed in vertical farm buildings were derived to use them as the basic data when we plan for a ubiquitous vertical farm building in residential space in the future. As result, the following uservices of ubiquitous vertical farm were proposed: u-notification service about the condition of crops from the aspect of growth management based on ubiquitous technology, remote/automatic control u-services, harvest information u-service for harvest management, recipe information u-service, and indoor air quality monitoring u-service, indoor environment adjusting u-service, and farm environment control u-service. Considering that many new buildings in Korea are residential buildings and many high-rise buildings are being planned, studies on vertical farm buildings must be continued.

Purpose - An appreciable number of small- and medium-sized exporters have continuously succeeded in their export marketplaces even though they do not possess enough resources. Advocating that affiliation with an export service-provider plays an important role in this phenomenon, we aimed to theoretically explain how export service providers' competences and relational factors drive small- and medium-sized exporters' competitive advantages in the long-run. Design/methodology - Drawing prominently on the resource-based view and the relationship-marketing theory, we built an empirically testable model. The model showed the roles of exporter capabilities, export service-provider competences, and relational factors on small- and medium-sized exporters' sustainable competitive advantages. Findings - The results of our research showed that exporter production and branding capabilities positively influenced their sustainable competitive advantage. In addition, export service-providers' marketing competence and relationship-building competence positively moderated the effects of exporter capabilities on their parties' sustainable competitive advantages. Finally, affiliation parties' interfirm trust and relationship commitment positively moderated the effects of export service-provider competence on the relationship between exporter capabilities and sustainable competitive advantages. Originality/value - Although prior studies have highlighted the effects of an exporter's resources on export performance, our research filled a knowledge gap of the effects of other resources on export performance. First, we proposed two types of export service-provider, competence marketing and relationship-building, influencing exporters' competitive advantage. Second, the effects of relational factors were proposed in the context of export affiliations.

The Tongdo temple have been transformed continuously since its first establishment about 1300 years ago. Nevertheless three critical elements specified by 'Jajangyulsa', founder of the temple have not varied over the times but rather strengthened and strongly combined. All elements and doctrines of the religion coexist and form a harmony within the whole of the temple. This researcher examined what changes, or combinations, in spatial formation were sought for such unique structures of the Tongue temple by focusing mainly on the Sangrojun area of the temple to obtain the following findings. First. unlike a work by a Japanese researcher 'Sekino Tadashi', the east yard of the main building was found located on the section line which corresponded to the separation line of Yungkuncheokdo(營建尺度=measure running) from the edge of the Keumkangkyedan(金剛戒壇 =Buddhist platform) embankment to the corner column of the Kamrodang. This was confirmed as a result of the review of photos shown in [Chosun Kojukdobo]. Second, the number of stairs used for the Keumkangkyedan was thought to become three when the temple was firstly restored in 1379 as a result that this researcher reviewed Chinese literature 'DoSun' and [Kyedandokyung(戒壇圖經)], records by 'Lee saek' and 'Jung Shihan', studies of Yungkun measure and actual changes in the temple. Then the temple was forth restored in 1705 when the second of the stairs was changed in area and height and at the same time grounded hard for a space for a Buddhist service. Third, the roof of the main building was probably changed in shape during the Koryo period when the plane structure, furnish arrangement, emphasized front, stone lanterns of the building and political factors of that time were all considered. Fourth, the main building was Initially designed to provide a Buddhist sermon service which was assumedly followed by a similar service at a Keumkangkyedan. Thus the main building had a small window on the northern side which might be opened up to look out or otherwise go outside like a door. However, the window was probably locked up like a surrounding wall since the main building was entirely repaired after the end of Japanese invasion of Korea in 1592.

Various new ITS Services to support autonomous vehicles. Infra-guidance service is also one of the new ITS services that have emerged to harmonize the traffic flow in mixed traffic by assisting autonomous vehicles. As a verification procedure to introduce a new ITS service, use cases and scenarios will be established for various spatial and situational ranges that may occur on the road, and limited test operations and living lab pilot operations will be performed. On the other hand, numerous cases occur depending on environmental factors such as the traffic volume at the time of service operation, weather and road geometric characteristics. This study presents a test scenario design method for verifying new ITS services, focusing on the infra-guidance service that is being researched as an emerging autonomous driving-supported technology.
