Building Information Modelling (BIM) has become the new international benchmark for efficiency in design, construction and maintenance of buildings. It is the platform that brings about collaboration between project stakeholders and improvement of project outcomes. With all its potentials, not much of the impact of BIM technologies has been felt in the Nigerian construction industry. This research aimed at assessing the readiness of the Nigerian building design firms to adopt BIM technologies. The research was exploratory in nature. A field survey was conducted with the use of structured questionnaire, self administered to a sample of building design consultancy firms (architectural, structural, M&E, quantity surveying, and multi-disciplinary design firms) within Abuja and Kaduna. The questionnaire sought the perception of the responding firms on the factors affecting BIM adoption in the Nigerian construction industry, and their level of readiness to adopt BIM technologies in their practices based on the four categories of readiness-management, people, process and technology. 42.26% response rate was achieved and used for analysis. ANOVA and DUNCAN post-hoc tests were used to establish the differences between the responses of the groups of firms, while means and standard deviations were obtained to establish the important factors affecting BIM adoption in Nigeria. The survey revealed that all the groups of Nigerian design firms are appreciably ready for the adoption of BIM technologies in their practice, with slight variations in their respective levels of readiness. 'Lack of awareness of BIM technology among professionals' and clients and 'lack of knowledgeable and experienced partners' were identified as the most important barriers of BIM adoption in Nigeria; while the most significant drivers are 'availability of well trained professionals' and 'cooperation and commitment of professional bodies to the adoption'. Education and training of building design professionals and cooperation of all stakeholders in the design and construction supply chain were recommended as part of measures to ensure successful adoption of BIM in the Nigerian construction industry.

본 연구는 평생학습자로 살아가야 할 이공계 대학생의 자기주도학습준비도와 학습유형의 특성을 알아보고, 자기주도학습준비도와 학습유형의 관계를 분석해보는데 목적이 있다. 이 연구를 수행하기 위하여 충남의 H대학교 이공계열 전공 학생 142명을 대상으로 자기주도학습준비도 검사와 Kolb 학습유형 검사를 실시하였다. 본 연구를 통해 나타난 연구결과는 다음과 같다. 첫째, 연구대상 학생의 자기주도학습준비도 전체 평균점수가 3.41로 나타나 Guglielmino & Guglielmino(1993)의 점수해석을 기준으로 할 때, 연구대상 학생의 자기주도학습준비도는 '평균'으로 볼 수 있다. 자기주도학습준비도의 하위영역별 통계치를 보면, '자신의 학습에 대한 책임감'이 가장 높게 나타났고, '학습에 있어서의 독립심과 자발성'이 가장 낮게 나타났다. 둘째, 연구대상 학생의 Kolb 학습유형 4가지 기본척도 분석결과 능동적 실험(AE)의 평균점수가 가장 높게 나타났으며, 추상적 개념화(AC)의 평균점수가 가장 낮게 나타났다. 연구에 참여한 이공계열 전공 대학생들은 Kolb 4가지 학습유형 중 확산형을 선호하는 학생들이 가장 많았고, 수렴형은 선호도가 가장 낮았다. 셋째, 자기주도학습준비도의 하위변인과 Kolb 학습유형 기본척도의 상관관계를 분석한 결과, 통계적으로 유의한 수준에서 관계가 있는 것으로 나타난 것은 다음과 같다. (1) 학습기회의 개방성, 배움에 대한 사랑이 구체적 경험과 관계가 있었다. (2) 학습기회의 개방성, 효율적이고 독립적인 학습자로서의 자아개념, 학습에 있어서의 독립심과 자발성, 배움에 대한 사랑, 미래지향성이 추상적 개념화와 관계가 있었다. (3) 학습에 있어서의 독립심과 자발성, 창의성이 반성적 성찰과 관계가 있었다. (4) 학습에 있어서의 독립심과 자발성, 미래지향성이 능동적 실험과 관계가 있었다. 넷째, 연구대상 학생의 자기주도학습준비도 평균점수를 상위집단과 하위집단으로 구분하여 Kolb 학습유형과 비교 분석한 결과, 자기주도학습준비도와 학습유형은 관계가 있는 것으로 나타났다.

Military technology transition is the process of transition from the science and technology environment to systems to supply effective weapon systems and support systems to the fighters. In case of technology transition decision, immatured technologies result in increasing acquisition cost and delaying schedule toward the objective system. In this paper, we proposed a method to identify and select critical technology elements by integration relations between technologies or components, for supporting technology transition and risk management of military R&D projects.

최근의 무기체계 연구개발에서 실패의 주요인은 요구되는 핵심성능의 미충족과 기술성숙도 부족이다. 이러한 실패의 가능성에 대한 위험관리를 위해서 기술성능측정 관리와 기술성숙도 평가의 수행이 필요하다. 하지만 일반적인 기술성능측정 관리 기법의 적용은 컴포넌트 수준 이하에 대한 측정으로 시스템 통합의 효과를 반영하는 데는 제한이 있다. 한편으로 시스템 통합에 대한 효과를 반영하기 위한 시스템 성숙도 측정 방법이 제시되었지만 성능과 기술성숙도를 분명하게 연계시키지는 못했다. 따라서 본 연구에서는 컴포넌트 수준으로부터 상방향으로 확대하여 시스템 수준에서의 기술적 성능 달성도 평가방법과 함께 시스템 성숙도를 연계하는 시스템 성능 달성도 측정 기법을 제시하였다. 이를 통해 무기체계개발에서 위험관리에 활용할 수 있게 된다.

This study aims to understand the importance of commercialization of research and development projects and examines key factors that allow successful technology transfer and commercialization. Given the characteristics of the railway research project, and assuming that R&D input factors would vary depending on the technology readiness level and the degree of research convergence, this study analyzes the moderating effect of each R&D input factor on technology transfer and commercialization to determine their eventual impact. Through this study, it was found that it was necessary to proceed to technology transfer and commercialization of the national research and development projects via strategic workforce composition and allocation of research funding given the subjects and development goals of R&D projects.

This study analyzed the effects of optimism and innovativeness, the two drivers of a consumer's technological readiness to use an augmented reality(AR) fashion shopping service within the framework of the Technology Acceptance Model (TAM). The survey was conducted on 249 people (males = 58; females = 191) in their 20s who were willing to participate in the AR experience. Data were analyzed using confirmatory factor analysis (CFA) and structural equation modeling by AMOS 22.0. The results indicated that a greater level of perceived optimism had a positive influence on the ease of use and usefulness of the technology. The findings also show that consumers with a high degree of innovativeness tend to have a higher level of playfulness toward AR fashion shopping. Regarding the effects of user beliefs, ease of use had a positive effect on the perception of usefulness and playfulness with higher levels implying a higher consumer intention to adopt an AR fashion shopping service. In addition, this study reveals the moderating effect of consumers with high-fashion versus those with low-fashion innovativeness. For the latter, technological innovation had an insignificant effect on playfulness, thus indicating that consumers with low interest in fashion did not enjoy AR fashion shopping even if the technology was highly innovative. Nevertheless, the analysis confirms the possibility that experiencing a fashion product through AR technology could replace the actual experience of wearing the products.

A mortar system is able to be fired more rapidly and concentratedly than other field gun systems. A mortar system can be easily manufactured because of its simple structure. It has also been supporting for the fire power of infantry because it can be carried conveniently. But a mortar system has demerits that are the limited firing range, poor accuracy and uncomfortable operability. Korean army plan to be operated rapidly and enlarge battle field in the near future. So weapon systems of Korean army must have longer firing range, automatic laying function and precision firing capability. This study suggests efficient developing concept of 120mm self-propelled mortar system through surveying the technical readiness level of current R&D and manufacturing ability.

SAR(Synthetic Aperture Radar) has the ability to generate high resolution images regardless of a weather condition(e.g. visibility good or poor and day or night, etc.). SAR is considered as one of the most important powers and needs for the future since it has been utilized in a number of important military fields such as early warning, urban defense, missile guidance system, etc. Additionally there are many civilian demands and applications in aviation, traffic control, earth and space explorations, weather forecast etc. This days, the ability to acquire and analyze information is needed to cope with the urgency of global politics and international changes. In this paper, technical survey and development review for SAR systems are investigated to derive the core and immature technologies of domestic defense industry.

시스템개발 프로젝트에서 기술성숙도(TRL; Technology Readiness Level)는 개발기간과 비용에 직접적인 영향을 미친다. 만약 프로젝트 주관기관의 핵심기술요소(CTEs)에 대한 기술 성숙도를 정확히 평가하여, 그에 따른 개발기간과 일정의 영향 정도를 세밀히 분석한다면, 개발이 진행되는 과정에서 예산 추가와 일정 지연과 같은 위험을 최소화시킬 수 있다. 본 논문에서는 기술성숙도가 항공우주개발 프로젝트의 개발기간과 비용에 미치는 영향을 분석하고, 무인기시스템 개발사업에 적용하여 개발기관의 기술성숙도 수준 차이에 따른 개발기간과 비용의 정량적인 변화를 분석하였다.
