전화를 거듭하고 있는 IT산업의 그 중심에서 스마트폰이 활약하고 있다. 국내 시장에서도 스마트폰은 급속하게 확산되고 있지만 현재까지도 소비자들이 왜 스마트폰을 사용하는지에 대한 실증적 분석을 통한 선행 연구는 드물다. 본 연구에서는 정보시스템의 사용자 만족과 습관이론을 바탕으로 스마트 폰 사용에 대한 원인과 결과에 관해서 실증적으로 검증하였다. 본 연구는 스마트폰 사용자 278명을 대상으로 분석하였고 인지된 유용성과 사용 용이성이 스마트폰 만족에 긍정적인 영향을 주는 것으로 나타났다. 흥미로운 발견은 사용자 만족이 스마트폰 사용 습관과 탐색적 사용에 (+)정의 영향을 주지만 충분한 활용에는 영향을 주지 않는 것으로 나타났다는 것이다. 이는 습관이라는 매개 효과가 충분한 활용에 영향을 주고 있으며 자기효능감의 통제변수가 영향을 주기 때문이라고 할 수 있다. 마지막으로 스마트폰을 사용하면 할수록 사용자는 탐색적으로 새로운 스마트폰 기능에 관심을 기울이는 것으로 조사되었다.

This study is to develop a diagnostic model for the effective introduction of smart factories in the manufacturing industry, to diagnose SMEs that have difficulties in building their own smart factory compared to large enterprise, to identify the current level and to present directions for implementation. IT, AT, and OT experts diagnosed 18 SMEs using the "Smart Factory Capacity Diagnosis Tool" developed for smart factory level assessment of companies. They analyzed the results and assessed the level by smart factory diagnosis categories. Companies' smart factory diagnostic mean score is 322 out of 1000 points, between 1 level (check) and 2 level (monitoring). According to diagnosis category, Factory Field Basic, R&D, Production/Logistics/Quality Control, Supply Chain Management and Reference Information Standardization are high but Strategy, Facility Automation, Equipment Control, Data/Information System and Effect Analysis are low. There was little difference in smart factory level depending on whether IT system was built or not. Also, Companies with large sales amount were not necessarily advantageous to smart factories. This study will help SMEs who are interested in smart factory. In order to build smart factory, it is necessary to analyze the market trends, SW/ICT and establish a smart factory strategy suitable for the company considering the characteristics of industry and business environment.

This study analyzed the smart construction safety cost included in safety management plans that are approved before construction. Specifically, it refers to the cost incurred in constructing and operating a safety management system using wireless communication and facilities. Based on the obtained statistical results, an activation policy for the inclusion of the smart construction safety cost in building safety management plans was proposed. The smart construction safety cost must be included in the safety management cost; notably, this is mandated by the Construction Technology Promotion Act. However, there are some problems with the inclusion of smart construction safety costs. To analyze the problems encountered when calculating the smart construction safety cost and including it in safety management plans, in this study, statistical analysis was performed using the data of 1,334 safety management plans received at the Construction Safety Management Integrated Information (CSI) from June to August 2021. The results show that only 50.7% of the safety management plans included the smart construction safety cost although the current law mandates 100% inclusion of these costs. Thus, it is apparent that the smart construction safety costs are only included in a low proportion of sites. In addition, the calculated smart construction safety costs were shown to have a small correlation with the construction cost; moreover, they appeared to be distributed at a constant cost level. In this context, it is believed that perfunctory cost calculations were performed at most sites since the effect of the construction cost on the smart construction safety cost was negligible. Therefore, it is necessary to improve the inclusion of smart construction safety costs by strengthening the authorization process of the approval institute of safety management plans. In addition, institutional support, such as guidelines that promote the calculation and inclusion of appropriate smart construction safety costs according to the characteristics of sites, are needed.
