A real-time three-dimensional vision is a passive system, which would support various applications including collision avoidance, home networks. It is a good alternative of active systems, which are subject to interference in noisy environments. In this paper, we designed a SAD correlator with respect to resource usage for a real-time three-dimensional vision system. Regular structures, linear data flow and abundant parallelism make the correlation algorithm a good candidate for a reconfigurable hardware. We implemented two versions of SAD correlator in HDL and synthesized them to determine resource requirements and performance. From the experiment we show that the SAD correlator fits into reconfigurable hardware in marginal cost and can handle about 30 frames/sec with $640{\times}480$ images.

The production of nuclear energy from thorium which is non-fissile material was a main issue until the middle of 1970's, because of the thorium's abundance as energy resources, its capability of breeding fissile material U233, and the reduction of long-lived actinides. However, to use thorium as nuclear fuel, some obstacles such as the necessities of external neutron source and long-term neutron irradiation for effective breeding, and the production of high radioactive isotopes in the course of thorium breeding cycle should be overcome. The difficulties to resolve these cons of thorium cycle became the reason of interruption of the related researches in the middle of 1970's. But in the 21st century, the change of societal perspective regarding nuclear energy and the appearance of accelerator-driven nuclear reactor shift those cons into pros and rehabilitate the study of thorium. The high activity of thorium cycle turned out to be a good option as higher resistance and easier detectibility of nuclear proliferation and the employment of subcritical accelerator-driven reactor as external neutron sources is considered to enhance the nuclear safety. In this study we compare the thorium cycle with the currently-used uranium cycle and analyze the technical status and perspective of thorium researches which use accelerator-driven reactors.

As the Moon's scientific, technological, and economic value has increased, major space agencies around the world are leading lunar exploration projects by establishing a road map to develop lunar resources and to construct a lunar base. In addition, as the lunar base construction requires huge amounts of resources from the Earth, lunar in-situ construction technology is being developed to produce construction materials from local lunar resources. On the other hand, the characteristics of lunar topography and resources vary spatially due to the crustal and volcanic activities inside the Moon as well as the solar wind and meteorites from outside the Moon. Therefore, in this paper, the geospatial analysis of lunar resource distribution was conducted to suggest regional consideration factors to apply the lunar in situ construction technologies. In addition, the lunar topographic condition to select construction sites was suggested to ensure the safe landing of a lunar lander and the easy maneuvering of a rover. The lunar topographic and resource information mainly from lunar orbiters were limited to the lunar surface with a low spatial resolution. Rover-based lunar exploration in the near future is expected to provide valuable information to develop lunar in situ construction technology and select candidate sites for lunar base construction.

As the technology commercialization of American universities has been greatly activated since the implementation of the Bayh Dole Act, that of Korean universities has been steadily increasing since the enactment of the Technology Transfer Promotion Act of 2000, due to numerous related laws, government support programs, and accumulated experience of technology transfer. However, the level of technology commercialization of domestic universities is still insufficient in comparison to that of advanced countries such as the United States. So, in this study, we tried to identify factors promoting technology transfer and start-ups in Korean universities by examining domestic prior researches carried out since 2000 using SLR (Systematic Literature Review) methodology. As a result of our analysis, researches in the field of technology transfer were the most studied while papers on start-up are actively increasing recently. As for factors influencing commercialization of technology, internal and external factors were identified. The former were categorized as human resource, technology and knowledge resource, financial resource, managing resource and strategy, university type, and education and culture, while the latter were grouped into consumer, region, and infrastructure. And then detailed factors were integrated in each field by systematic mapping. Our study has its meaning in that it systematically accumulated the results of researches on technological commercialization of Korean universities and identified areas that are lacking or need additional research. And the integrated promoting factors for technology transfer or start-up can also be used as a checklist for universities or public institutes.

Recently, the synthetic aperture radar (SAR) has been increasingly in demand due to its advantage of being able to observe desired points regardless of time and weather. To utilize SAR data, first of all, many pre-processing such as satellite orbit correction, radiometric calibration, multi-looking, and geocoding are required. For analysis of SAR imagery such as object detection, change detection, and DEM(Digital Elevation Model), additional processings are needed. These pre-processing and additional processes are very complex and require a lot of time and computational resources. In order to handle the SAR images easily, the institutions that use SAR images develop analysis tools and provide users. This paper introduces the function and characteristics of representative SAR imagery analysis tools.

Data is an important resource to expect new value as 21st-century crude oil. In the shipping industry, despite the existence of numerous maritime data accumulated through ship operations, it was negligent in developing a business model with the data. This paper identified major demand sources and demand types based on the type and availability of maritime data surveyed through interviews with experts in the shipping industry and academia. Considering the characteristics and demands of these maritime data, this paper presented a private-type and public-interest business model. In the case of the private-type model, it creates additional added value by using maritime data and uses mainly ship internal data. The public-type model is to seek public safety and social benefits and mainly uses external data. A great synergy effect can be expected when combined with public services such as maritime survey, vessel traffic service, maritime environment management, and meteorological service. This study is expected to contribute greatly to the spread of the proposed business models throughout the shipping industry.

인구증가와 경제발전은 도시화를 촉진시키며 도시에서 물과 에너지 사용량을 급격히 증가시켰다. 도시 물순환 시스템에서 용수를 공급하기 위해 에너지가 사용되고 에너지 발전을 위해 물이 필요하듯이, 물과 에너지는 긴밀한 연결 관계를 가지고 있다. 도시에서 이러한 자원을 효율적으로 관리하기 위해서는 물과 에너지 사이에 존재하는 복잡한 관계를 고려하여 분석할 필요가 있으나 기존의 도시 물관리는 부문별로 독립된 접근방식에 의존하기 때문에 이를 설명하기는 어려웠다. 이러한 한계점을 극복하기 위해 부문 간 존재하는 복잡한 관계를 반영하고, 상호연관성 및 영향 효과에 대해 분석 가능한 통합적 접근방식인 넥서스 접근법이 점차적으로 활용되고 있다. 본 연구에서는 넥서스 관점에서 국내 광역지자체별 상수시스템의 물-에너지 관계를 분석하고, 이를 바탕으로 도시 물관리 전략 및 실행계획을 제시하는 것을 목적으로 하였다. 넥서스 관점에서 상수시스템의 물-에너지 이용을 분석하기 위해 2011년부터 2020년까지 10년간의 자료를 활용하여 광역자자체별 넥서스 프로파일링을 수행하였다. 분석 범위 설정, 자료 처리, 기본 경향 분석, 영향 요인 도출, 스냅샷 및 궤적 분석, 원인 도출의 절차로 진행되는 프로파일링을 통해 상수시스템에서 물 사용량과 에너지 사용량의 현황과 거동을 파악할 수 있었다. 인구변화, Lpcd(litres per capita per day) 변화, 원수 수입량 변동과 같은 외부 영향(부산, 대구, 인천, 울산, 세종), 시스템 개선 등을 통한 도시여건 개선(광주), 입력자료의 오류 또는 부정확성(대전, 울산, 제주)과 같은 도시별 물-에너지 사용량 변화에 대한 주요 원인을 도출할 수 있었다. 그리고 이를 바탕으로 각 광역지자체별 향후 추세 및 개선방안을 제시하였다. 본 연구에서는 넥서스 관점에서 국내 통계자료를 활용하여 광역지자체별 상수시스템의 물-에너지 관계를 분석하여 국내 도시 상수시스템 내 물과 에너지 사용에 대한 과학적 근거를 제공하였다. 이를 통해 향후 각각의 도시 여건에 맞는 실제 정책 수립에 활용될 수 있을 것으로 기대된다.

The service that has been recognized as both a non-productive activity and auxiliary activity of manufacturing have become the driving force of the customers' demand with the 'service' itself. The service base is expanding and evolving rapidly. It is important to look at changes in service concepts to understand service systems. Because the service system itself has a cyclic nature based on the concept of service, it can help in the study and the "how" of service by looking at changing the system according to the evolution of the service concept. The ability to organize and utilize relationships is considered to be an important factor for managers in the service economy era. However, the attention of corporate is focused on their internal capabilities and they are familiar with external resources (knowledge and competence of customers). In this case study for each type of service, we analyzed the activities of interacting service providers-consumers in service relationship, and constructed a new service system model emphasizing intangible value and long-term outcome. This study is worth re-examining the role of customers in today's service economy era and actively utilizing a new service model for business performance.

Under the global economic competition, company competitiveness depends on creating high performance through effective human development. It is also a tendency to analyze organization members'competencies and outcomes, develop competency model, and apply the model to developing and managing human resource in each organization. Therefore, this study figures out the present condition of development of competency model and its application to examine the degree to which the competency model, which has been introduced to Korean companies for the use of competency diagnosis of members, is being utilized. For this purpose, survey items were created by expert council and advisory committee and survey was conducted for Korean corporations. The result shows that most of the companies, regardless of size and type, develop their own model by referring to outside models, or use models developed by consulting company lead. Therefore, it is urgent for the companies to develop model appropriate for the peculiarity of each company. Second, while the main reason to introduce competency model was to reinforce workers' competency, models developed have not widely utilized in HRM overall. There is a need to overcome a limit of utilization of models. Third, Majority responded that they, regardless of size and type, upgraded models or did not upgrade at all due to change of work environment. There is also a need to systematize follow-up care of the models. This is a primary research to examine the present condition of development of competency model and its application in company so that it can be used as springboard to study in-depth inside condition of Korean company using competency model and condition of particular positions of company members.
