The main purpose of this paper is to find the phase-in of BIM adoption by focusing on the level of integration. BlM should be aimed at integration and collaboration of all parties furnishing design and construction services to increase the productivity. Therefore, the degree and depth of integration for project collaboration is very important to BlM design process. One of the key advantages of full integration is that is to facilitates the development of detailed information much earlier in the entire design process to improve collaboration among stakeholders. Such integrated use is the ultimate method, but even so, it's not the precondition of BlM. One of the key advantages of relatively low integration as a transition phase is to adopt the BlM earlier than full integration. Such transitional and non-integrated BIM can also reduce the possibility of trial and error in BlM adoption. Therefore, this paper focused on non-integrated use of BlM as a substitute of full IPD by analyzing obstacles in BIM adoption.

모바일시장의 흐름이 피쳐폰에서 스마트폰으로 넘어가는 과도기적인 시점에서 하드웨어 기술은 크게 발달했지만, 사용자가 주소록이나 발신자정보표시서비스 등의 여러 정보들을 통합 활용함에 있어서 사용자 중심적인 애플리케이션 제작에는 부족함이 있다. 본 논문에서는 스마트폰의 다양한 하드웨어 기능(GPS, wifi, 등)들을 이용하여 기존 피쳐폰에서 사용되어지던 다양한 정보들을 효율적으로 통합하여 활용할 수 있는 방안(통화 수신자 정보 자동검색 등)에 대해 제시하고, 오픈소스의 장점을 갖고 있는 안드로이드 기반의 스마트폰에 설계하였다.

This study is to investigate the factors affecting the usage intentions of 5G service between 5G service subscribers and non-subscribers based on the Integratively Extended Technology Acceptance Model in the initial B2C 5G service market. We designed the integratively extended technology acceptance model to find the more specific factors to affect the usage intentions by integrating the exogenous factors including the technical factors, the social factors, and the personal factors with the ETAM(Extended Technology Acceptance Model). Referring to the previous studies, we constructed the hypotheses of structural influence relationship from the exogenous factors to the dependent usage intentions factors through the mediating belief factors. We designed the 5G service usage intentions model based on these hypotheses and operational definitions of the factors. Using the analysis of SEM(Structural Equation Model), the proposed model and the hypotheses were empirically tested by the data collected from 245 subscribed respondents and 245 non-subscribed respondents. As a result, the perceived ease of use has an effect on the perceived usefulness and enjoyment, and the perceived usefulness/enjoyment and the personal innovativeness have positive effects on the usage intentions of both groups.
