최근 국내에 연구개발을 하는 과정에서 발생하는 보유(연구성과물)기술의 유출 가능성이 증가하고 있다. 이러한 유출사고를 대비하기 위해 지속적으로 보안투자를 하고 있고, 보안 관리체계를 마련하여 시행하고 있다. 하지만 실질적으로 도움이 되는 연구보안을 위해서는 연구개발 과정의 특정부분이 아닌, 전체적인 연구개발 흐름을 대상으로 유기적으로 연결되는 연구보안 관리체계를 설계할 필요가 있다. 이 논문은 먼저, 일반적인 연구개발 프로세스를 파악하고, 연구개발에 필요한 보안활동을 알아본다. 다음, 조사한 보안활동을 연구개발 프로세스 흐름에 맞게 배치하여, 전체적인 관점에서의 연구보안 관리체계를 설계하고자 한다.

The Fintech services provide innovation to financial services users using various mobile devices and computers in wired and wireless communication environments. In this study, we develope a theoretical research framework to explain the psychology of Fintech services users based on a cognitive, affective, and conative framework. Using this framework, this study analyzes the relationships between the cognitive characteristics (i.e., innovation, relative advantage, ease of use, and usefulness), emotional characteristic (i.e., attitude), and behavioral characteristic (i.e., actual use) toward Fintech services users. This study conducted an online survey of people who have experienced using Fintech services. And the data of the collected Fintech services users was analyzed using structural equation model software (i.e., SMART PLS 2.0 M3). The results of the empirical analysis show the relationships between innovation, relative advantage, perceived usefulness, perceived ease of use, attitude, and actual use of Fintech service users. The results of this study provide useful information to improve the practical use of Fintech services users in the Internet of Things (IoT) environment.

Metadata and folksonomy are two main approaches in representing, organizing, and retrieving resources in the current information environment. Many researches have conducted studies to combine of metadata and folksonomy in order to utilize the strengths of both approaches. This research proposed an approach to utilize both metadata and folksonomy in representing resources by using microcontents. Microcontents in this research is a conceptual structure that reflects dynamic characteristics of folksonomy and the structure of metadata. By connecting folksonomy with metadata through this microcontents structure, both approaches can maximize their strengths and minimize their weaknesses in representing, organizing, and retrieving resources.

정보기술의 발달은 산업 전반에 매우 큰 영향을 주는 요소가 되고 있다. 이러한 정보 기술을 프로젝트에 효율적으로 사용함으로써 기존 프로젝트의 수행에 있어 불합리한 점을 제거하고 개선함은 물론 전체 프로세스에 대한 경제적인 효과를 기대할 수 있다. 특히 건설부문은 계획, 설계, 시공 및 유지관리에 이르기까지 다양한 공종이 유기적으로 연결되어 수행되는 바, 유비쿼터스 컴퓨팅 환경을 실제 건설공사의 현장에 접목하려는 시도는 의미가 크다고 볼 수 있다. 이른바 u-city 건설은 IT기반의 첨단공공서비스가 사회전반에 제공되는 도시를 말한다. 최근에 기존 도시를 첨단화하거나 완전히 새로운 신도시를 건설하는 지방자치단체 또는 국가주도형 사업은 대부분 첨단 유비쿼터스 기술을 적용, 도시 서비스의 차별화를 구축하고 있다. 이에 본 논문은 도시의 근간을 이루는 토목사업중 도로를 설계함에 있어 관련되는 유비쿼터스 요소기술을 도출하고, 이를 설계에 반영하므로 u-건설의 실질적인 접근방향을 모색하고, 동시에 지속적인 u-건설이 가능할 수 있는 기반을 삼고자 한다.

Though Quality Management(QM) is key determinant for corporate success as shown in Jappanese cases, however, its performance wasn't translated into the context of profitability, which is a good managerial means. Meanwhile the quality cost theory is a different attempt to measure the quality management performance with a financial scale, which doesnot have a reasonable measure. This study suggests a new approach to measure the performance of quality management using ABC(Activity-based Costing), and explains its usefulness with a case study.

오늘날 비즈니스의 글로벌화, 사업장의 분산화는 필연적으로 영상회의의 활성화를 가져왔으나, 기 구축된 SD(Standard Definition)급 화질의 영상회의는 실감성 및 장시간 사용시 피로감 등에 따른 이용율 저조로 기대 만큼의 성화를 이루지 못하였다. 또한 기존 영상회의 시스템에서의 dec는 보조적 채널, 시스템 조작과 운영의 복잡성, 낮은 해상도로 인한 표정 및 눈짓 등의 요소 포착이 어려운 한계를 극복하지 못하였고, 기업들은 기업 내부 및 국내외 타기업들과의 협업을 위해 막대한 비용과 시간이 요구되고 있는 실정이다. KT는 기존 영상회의 문제 극복을 위해 서울<->대전 연구소간 전용선 연결, 비용 및 여러 site 확장을 위한 VPN으로의 전환 방안등 최상의 영상회의 구축을 위한 검토를 통해 Full HD실감 화질의 영상회의를 구축하였으며, 향후에는 Full HD 데이터 압축 기술 향상 및 데이터 전송 방안에 대한 더 많은 연구가 필요하다고 판단된다. 본 고에서는 KT에서 구축한 영상회의 사례를 중심으로 기본적인 기술과 구조, 국내외 시장의 현황 및 활용 방안에 대해 논하였다.

Port of competition in the domestic market share of a particular port is gradually lowered. This is growing influence of external factors in accordance with changes in the market environment and the open economy. This liquidity factors have difficulties to explain. Using real-time data to identify network effects, means for establishing practical measures will have.

We rethink human existence as a assemblage through intersectionality by comparing autopoiesis and sympoiesis systems with reference to science fiction protagonists such as Ghost in the Shell, Neuralink, Camille, a genetic hybrid, and San Ti against the background of neo-materialism. Our findings reveal that, first, radical sympoiesis is characterized by the dissolution of individuals and boundaries, and attempt to explain existence solely through heterogeneous linkage and fusion; second, by ignoring the capacity for autonomous thinking at the individual level, they are unable to fully recognize the destructive nature of hybrid co-production or to develop practical responses to it. Third, we suggest that if the very survival of humanity is threatened by heterogeneous linkage, we should pay more attention to our identity as autonomous members of a autopoietic system rather than to heterogeneous sympoietic networks and we should also pay attention to the role of individual units in stabilizing self-regulation. Through this study, we aimed to contribute to overcoming the limitations of neo-materialism by arguing that it is likely to fail to provide an adequate practical vision if it is limited to describing the hybrid connections that recur through the intersection of beings, and by urging us to define the identity of the human species from a new perspective by utilizing various SF stories that trigger the imagination of destructive interactions between beings, and to explore the autopoiesis in terms of symbiotic interactions based on a certain level of boundary and self-regulation.

Routing and wavelength assignment(RWA) problem is an important issue in optical transport networks based on wavelength division multiplexing(WDM) technique. It is typically solved using a combination of linear programming and graph coloring, or path selection based graph algorithms. Such methods are either complex or make extensive use of heuristics. In this paper we propose a novel and efficient approach which basically obtains the maximum edge disjoint paths (EDPs) for each source-destination demand pair. And those EDPs obtained are stored in Lookup Table and used for the update of weight matrix. Routes are determined in order by the weight matrix for the demand set. The comprehensive computer simulation shows that the Proposed algorithm uses similar or fewer wavelengths with significantly less execution time than bounded greedy approach (BGA) for EDP which is currently known to be effective in practice.

In the era of the 4th industrial revolution in order to cultivate excellent human resources equipped with international competitiveness and new technologies the university's engineering education is gradually improving through a number of studies. Comprehensive design in engineering is a course that emphasizes the importance of design education and nurtures future talents that are practically needed in the industrial field. In this study focusing on the researcher's 2019 engineering-related comprehensive design courses students apply new technologies learned in college to actual practice propose creative ideas and develop practical results that solve problems of local welfare facilities. The curriculum was described in which students took the initiative to find problems in community welfare facilities and developed VR contents for disaster response education for the socially disadvantaged. Through this study, students solved the motion limitations of existing earthquake VR contents by connecting them with motion chairs. As a result, it is meaningful that students contributed to the local community as well as cultivating their ability to adapt in the field.
