The purpose of this study is to analyze the relations of innovation and productivity following the introduction of ICT and the effects in the process of innovative investments activity-innovation-productivity, not only by finding causes and effects. For this purpose we conducted surveys of SMEs classified into 7 categories by type of business. To put it concretely, this study was performed to find out the foactors which allow companies to secure competitiveness by enhancing of innovative measures through ICT, and to further analyze the political implications for the development of small and medium-size business by conducting an empirical analysis of the process, from the determination of innovative investments all the way through to production. Analysis model used CDM model using econometric methods such as multiple regression analysis and multinominal logit analysis to produce results. Also we established and analyzed models of innovation investment determinants, innovation determinants and productivity determinants to analyze specifically the relations between ICT and productivity.

This paper aims to provide a better understanding about how Information and Communication technology (ICT) has diffused. The investigation is conducted with the consideration of ICT evolution in terms of technological change and usage pattern. The definition used is presented as 'the ICT is a process of convergence of technologies between information-processing and information-transforming technologies, mainly due to the advent of microelectronlcs'. After examining technological changes of ICT, the diffusion path of ICT is traced through the usage ratio in total input and/or investment based on Input-Output tables (I-O). It shows that the evolution of ICT from the change of usage pattern is an up-and-down usage pattern rather than a uni-modal usage time path. With this recognition, the diffusion index is prepared. JEL classification : C43, L63, O33.

Tracking ICT applications on construction business processes is critical to the success of ICT-applied construction projects. Existing IDEF0 is a representative modeling method for visualizing and analyzing business processes. It defines a construction production process into a visual information model, hence, encouraging the project participant to understand the activities, their deliverable, and control flow of the process. However, IDEF0 dose not lend itself to ICT-applied construction processes, because it does not provide a mean to define how, in what order, by which each and every activity that ICT applied implements. This paper presents a new business modeling method that improves the traceability of ICT application (IAMB: ICT Application tracking Model for Business process) for construction management. The IAMB contributes to handle the sophisticated features of construction management processes to which ICT are applied. The method categorizes the process into three types: management, construction, and information exchange. The validity of IAMB was confirmed by analyzing the performance when it is used for tracking each modeling step of lift reservation process which making use of ICT. The test case provides an admissible evidence that the method encourage to define who, what, how, which order, and by which ICT tools the construction process exchanges production information.

Privacy-right infringement using unmanned aerial vehicle (UAV) usually occurs due to the unregistered small UAV with the image data processing equipment. In this paper we propose that privacy protection acts, Personal Information Protection Act, Information and Communications Network Act, are complemented to consider the mobility of image data processing equipment installed on UAV. Furthermore, we suggest the regulations for classification of small UAVs causing the biggest concern of privacy-right infringement are included in aviation legislations. In addition, technological countermeasures such as recognition of UAV photographing and masking of identifying information photographed by UAV are proposed.

In order to develop a smart cultivation facility based on ICT (Information Communication Technology), a cultivation house was selected. Sensor devices were installed to monitor any changes in the cultivation environment. A control panel was constructed to monitor and control the data on environmental changes collected by the sensors. To efficiently manage the proceedings of the cultivation environment, the cultivation process was divided into 4 stages. We designed an environmental control module using these processes. PC and mobile phone software were designed for remote monitoring and control to develop a smart cultivation system that can conveniently manage the cultivation environment and produce mushrooms in a more stable manner.

Purpose: The purpose of this study was to investigate the effects of Interferential current stimulation therapy(ICT) on pain, balance, and walking ability of elderly patients with chronic low back pain. Methods: Twenty participants were randomly assigned to ICT group (2 males and 8 females) and placebo ICT group (3 males and 7 females). Participants were ICT and placebo ICT for 20 minutes, and the pre- and post-VAS, TUG and postural balance were measured. Results: The ICT group showed significantly decreased pain scores in the elderly patients with chronic low back pain (p<.05) than the placebo ICT group. The postural fluctuation with eyes opened and closed was significantly lower than the placebo ICT group(p<.05), and the ICT group showed remarkable improvement (p<.05). Conclusion: ICT was expected to improve decrease pain, improve postureal sway and walking ability remarkably. Therefore, It was expected that the application or ICT would be an effective method for elderly patients with Chronic Low Back Pain.

It is in the vortex of the Fourth Industrial Revolution in all areas of our society. Education is no exception. We all know that software is at the center of the education in the 4th industry revolution. It is very important for students to survey the ICT background in order to be good at software education. The OECD PISA has surveyed ICT background of students in a three-year cycle from 2003. This study analyzes PISA ICT statistical data based on the data released in April 2017. We compare and analyze the availability and usability items among the 81 items of the ICT background of the students. The results of linear regression analysis showed that Korea was the lowest among OECD countries. ICT availability is ranked 28 out of 30 countries and ICT usability is ranked 31 out of 31 countries. This reflects the fact that ICT education is not implemented in the country since 2008. For the students who will be the leaders of the future society, ICT education that had implemented in 2000 should be carried out quickly.

The ship surveyor makes a scheme of reasonable ship operation by examining whether the ship has been properly constructed in accordance with the rule of classification societies and international conventions or whether the facilities of the ship in operation meet the standard stipulated by law. Even though the ship surveyors of classification society generally consist of people who have the skill of design or operation of a ship, it takes a long time to train a surveyor to the maturity level. This paper describes the development of survey simulator based on virtual ship environment that enables the surveyor minimize trial and errors to survey the ships. By using VR(Virtual Reality) based survey simulator, surveyors possibly achieve improvement of competence in survey quality by means of safe and immersive training environment. In order to improve the usability and utility of the VR simulator, the ship 3D model has been generated using 3D CAD model for design and production in shipyard. Through this, we suggested the possibility of consistent use of 3D model as the digital twin of a ship.

기후변화는 이제 환경의 문제를 넘어 정치적, 경제적 문제로 진화되어 있는 상태이며, 인류 생존을 위한 환경적 문제로서의 중요성 뿐만 아니라 국가 경제의 보호와 성장에 중요한 지렛대 역할을 하게 되었다. 정보통신기술(ICT)은 기후변화 문제에 대처하여 다양한 산업 분야에서 기술적 해결책의 하나로써 활용되어 저탄소화를 촉진시킬 수 있는 효과적 수단으로 인식되고 있다. 이에 따라 관련 국제표준화 활동이 2008년부터 시작되어, 2009년에 표준화의 기반이 마련되었고, 2010년부터 본격적인 표준 개발 활동이 시작될 것으로 전망된다. 이에 대한 전반적인 현황과 전망을 소개하도록 한다.
