  • 본 연구는 기존에 운영 중인 항만건설통합정보시스템의 활용성과 시스템 운영관리의 효율성을 높이기 위해 시스템을 통합화하였다. 도로와 항만 건설사업관리는 대상목적물만 다르고 기본적인 업무프로세스는 유사하다. 따라서 통합 개발기간을 단축하고 안정적으로 통합화하기 위해 항만건설통합정보시스템을 기존에 운영하고 있는 도로건설사업관리시스템으로 통합하는 방식으로 추진하였다. 도로건설사업관리시스템은 항만건설통합정보시스템보다 시스템 사용이 쉽고 편리하며 건설사업관리 업무프로세스 지원 및 관리기능이 안정적으로 설계되었다. 본 연구는 시스템 통합화 과정에서 겪었던 애로사항과 이를 해결하기 위한 방안을 제시하였다. 타 시스템을 통합화할 경우에 본 연구 결과를 활용한다면 반복적인 시행착오를 미연에 예방할 수 있을 것으로 사료된다.

  • We fabricated a $0.18-{\mu}m$ gate-length AlGaN/GaN high electron mobility transistor (HEMT) on SiC substrate fabricated by using two-step gate recessing which was composed of inductively coupled plasma (ICP) dry etching with a gas mixture of $BCl_3/Cl_2$ and wet chemical etching using the oxygen plasma treatment and HCl-based cleaning. The two-step gate recessing process exhibited an etch depth of 4.5 nm for the AlGaN layer and the clean surface of AlGaN layer at the AlGaN/gate metal contact region for the AlGaN/GaN HEMT structure. The recessed $0.18{\mu}m{\times}200{\mu}m$ AlGaN/GaN HEMT devices showed good DC characteristics, having a good Schottky diode ideality factor of 1.25, an extrinsic transconductance ($g_m$) of 345 mS/mm, and a threshold voltage ($V_{th}$) of -2.03 V. The recessed HEMT devices exhibited high RF performance, having a cut-off frequency ($f_T$) of 48 GHz and a maximum oscillation frequency ($f_{max}$) of 130 GHz. These devices also showed minimum noise figure of 0.83 dB and associated gain of 12.2 dB at 10 GHz.

  • In 2011, Government introduced "IT Convergence Technology Prediction Survey 2025". This report includes 10 ICT industries. Convergence was combined with a word 'digital'. Digital convergence means a service or new product which appeared through fusion of unit technologies in information and communication regions. The effects of convergence technologies and social phenomenons are visualized in overall regions of society such as economy, society, culture, etc. In this paper, we described a prospects and technologies needed in digital convergence environment. And we described IT-Building, IT-Car, IT-Medicine, IT-Textile which was related with our lives in today among 10 ICT industries.

  • 본 연구는 홍삼 등급판정 과정에서 내부 조직 치밀도 분석을 위해 의료 영상 분석 방법을 이용하여 적외선 영상 측정기기를 개발하였다. 기존 홍삼 내부분석방법은 수동으로 암실환경에서 강한 조명을 홍삼에 투과하여 사람 눈으로 직접 판별하는 과정을 거친다. 이러한 기존 검사 과정은 작업 비효율성과 불균일한 검사기준으로 제품 품질 신뢰도 저하의 단점을 가져온다. 이러한 문제점을 해결하기 위해 본 연구는 적외선 조명환경에서 자동 측정이 가능한 홍삼 내부 측정기기를 개발하였다. 개발된 장치는 홍삼의 빛 투과 특성을 응용한 920nm 파장대역의 적외선 조명기구, 조명 제어회로, 적외선 대역 촬영이 가능한 영상 측정 카메라 장치, $0.9^{\circ}$의 간격으로 $360^{\circ}$ 홍삼 영상취득이 가능한 회전 엑츄에이터로 구성이 된다. 본 연구에서 제안 하는 홍삼 단층 영상분석 방법은, 홍삼을 $0.9^{\circ}$ 간격으로 회전시키어 $360^{\circ}$ 홍삼 내부영상을 취득하여 라돈 변환(Radon transform)을 통해 사이노그램(Sinogram)으로 재구성 하였으며, 역 라돈 변환(Inverse Radon transform)을 통해 단층 영상복원(Back-projection)알고리즘을 구현하였다. 이 결과 홍삼을 절단하지 않고 홍삼 내부 단면영상 획득이 가능하였으며 내공(內空), 내백(內白)의 유무를 판단하고 직경을 파악할 수 있었다. 이를 토대로 등급 판별 공식을 산출하면 신뢰성 있는 홍삼 등급 자동화 측정기기를 개발할 수 있을 것으로 기대된다.

  • ICT-convergence cluster is considered as critical policy means because it can create higher value-added products and services in the era of creative economy. Previous research has focused on comprehensive ICT-convergence cluster strategy based on Porter's diamond model. This paper adopted AIDA(Attention, Interest, Desire, Action) model and investigated a specific domain of government supporting policies related to non-R&D support. For two weeks, we gathered and analyzed 181 data from companies located in Chungbuk province. The results showed that support for technology, commercialization, and participation conditions positively leads to companies' interest in ICT-convergence cluster, which, in turn, makes positive impact on their intention to participate in it. It is significant that this paper verified AIDA model in the Government-to-Business(G2B) context. Future research will need to adapt AIDA model to national projects.

  • President Park Geun-hye Administration has established the Ministry of Science, ICT and Future Planning (MSIP) to build a creative economy using Information and Communication Technology (ICT). July 2, 2013, The National Assembly has legislated the special act on the ICT promotion and convergence so called special ICT Act. This special ICT Act has reduced the legal basis through legislative process and departmental agreement. Therefore many experts worried that since the MSIP's key functions and roles are being reduced, there will be a limit to the MSIP's endeavor for the advancement of science technology and the ICT promotion and convergence. The establishment of the Agency, together with the formation of 'IT Strategy Committee', is considered to be one of the core items of the Special Act on ICT. MSIP originally planned to integrate the ICT R&D functions scattered across many governmental organizations, including Korea Communications Agency (KCA), KEIT and Korea Creative Contents Agency (KOCCA), into the Agency to separate the national ICT R&D from private R&D and streamline the process of 'discovery-selection-evaluation-commercialization'. The analytical results in this study are supposed to the establishment of efficient ICT governance systems as the practical strategies to actively cope with the changes of ICT convergence environment. It is also expected to the revision on the special ICT Act in the ICT budget and governance. Therefore, MSIP should cover research and development (R&D) as well as major ICT promotion functions to a creative economy.

  • This study is to examine the randomized controlled trials abroad studies on ICT-based convergence studies in the elderly, and to investigate the types and effects of ICT-based interventions. Eight studies that meet the selection criteria were selected from 326 studies identified by three databases and hand-searching. As a result of this study, the most commonly used ICT were the three internet, followed by two tablets and mobile phones, one twoway videoconferencing, one Kinect, one robot, and one Blood Glucose Monitoring System. These results could be used for ICT-based convergence studies in Korea, and further studies should be conducted with higher quality studies such as randomized controlled trials.

  • The Information and Communication Technologies (ICT) sector is undergoing a fundamental transformation. Determinant factors in this transformation process are deregulations and technological advancements. From the value chain perspective, industry convergence plays the most crucial role in the transformation of the established telecommunications and media industries. The objective of this paper is to validate the impact of convergence on the business performance using empirical data. To identify the various effects driven by industry convergence, we analyzed the relationships between firm's degree of convergence and the business performance using regression analysis. From the empirical result with the 2002-2005 data, it was found that the convergence across ICT sectors improves the business performance measured by Tobin's q significantly and this is only a recent phenomenon. These results are consistent with the conjecture that higher degree of convergence is becoming more associated with higher market value.

  • While the 4th Industrial Revolution (4th IR) is actively being discussed in Korea, the core and common point is that in the era of the 4th IR, computer networking is becoming more common due to the generalization of ICT(Information and Communication Technology). There may be a variety of factors that have allowed ICT to occupy a core position in the 4th IR, but the most important may be the position of ICT as a foundation technology. ICT has important technical value in itself, but when it is converged with other technology or industry, or when it acts as a foundation technology of such technology or industry, it greatly improves the value of existing technology or industry. Thus, this paper focused on ICT, the core technology of the 4th IR, to examine the past, present and future of ICT-related R&D and ICT-based convergence industries. In other words, the purpose of this study is to identify which areas ICT has been actively researched from past to present and what changes have been made in such areas.
