The second volume of the Iwakura Reports is the writing on Britain. What is interesting, here, is the fact that the mission had visited the large factories in the major industrial cities. The editor of the reports in particular recorded the productive processes of goods at many factories, and wrote his own impressions of the landscapes of those cities. Those records let us know the real situation of the British economy at the time. Japanese historians admit that the activities of the Iwakura mission largely contributed to Japan's modernization. But there are few studies that analyzed the second volume of the reports which had mainly described modern factories and industrial cities. The purpose of this paper is to summarize the records of the reports on the British industry, and to examine what they recognized from the industrial civilization. The Iwakura Reports would furnish important information to the notables that had initiated the early industrialization in Japan. After the mission's visit, some British companies' export to Japan increased rapidly. What is more important, however, is that the British economy was losing its own vitality in the late Victorian age in which Japan began to be rapidly industrialized. During the Japanese industrialization, some Japanese diplomats and factory-owners might have realized the decline of the British industry. Britain began to be overtaken by her rival countries such as the United States and Germany. The Iwakura Reports do not let us know the change of the British manufacture in the late nineteenth century. Later, the leading figures of Japan's industrialization might focus on the rise of Germany or America. As the Iwakura mission had visited Britain in the early stage of the competition between Britain and other rival states, they could not know the real situation of the British economy. Furthermore, with compiling his manuscripts, the editor of the reports could not help being based upon the factory-owners' explanations and their brochures. This is the reason why he focused only on the excellence and competitiveness of British manufacture.

The innovation ecosystem provides benefits and challenges for multiple institutional actors like universities, industry, government, NGOs, and private funding agencies, as well as individuals in a rapidly evolving and dynamic environment. First, we describe the changing role of universities-whereby, the support of innovation and entrepreneurship is developing into a core mission of universities. We then describe strategies within the United States and globally to help students learn about innovation and entrepreneurship. Finally, we explore the benefits and challenges of technological innovation for economic development, emphasizing how such development relates to the global problem of underprivileged communities, both in developed and developing countries, and the special concerns of economic development for developing countries.

기술융합을 통해 R&D 경쟁력을 확보함과 더불어, 융합의 정도를 측정하고 이를 기반으로 융합을 유도하기 위한 전략에 대한 관심도 함께 증대되고 있다. 본 연구에서는 출연연의 융합연구전략을 도출할 수 있는 데이터 기반 모형을 제시하였다. 우선적으로, 출연연 연구과제의 융합특성을 기술고유의 속성과 행위자의 행태 속성으로 구분하여, 각각의 대리변수(Rao-Stirling 지수, Herfindahl-Hirschman 지수)계산 방법을 고안하였다. 이들 대리변수를 두 축으로 출연연 융합맵을 설계하였으며, 이를 통해, 출연연 연구과제가 4개의 속성(Alliance-Intra, Alliance-Inter, Competition, Mission Oriented)으로 구분됨을 알 수 있었다. 이와 같이 설계된 융합맵을 기반으로 융합지수를 측정하여 출연연 간 30대 융합연구 가능영역을 도출하였다. 이러한 과정을 통해 출연연 연구과제의 기술융합 현상에 대한 보다 정확하고 객관적인 분석을 수행할 수 있으며, 이를 바탕으로 융합연구 추진을 위한 정책에 참조할 수 있는 유효한 가이드라인을 제공할 것으로 기대한다.

The rising demand for the high efficiency and high covertness in UAV motivates the miniature design of the high performing mission sensors, or payloads. One of the promising payload sensors, EO/IR sensor has evolved satisfying its demands and became the main stand-alone mission sensor for 200kg-range UAV. One aspect in development of EO/IR sensor concerns lack of specification criterions to represent its performance. Even though the high demand and competition among each manufacturer caused EO/IR features subject to rapid change collateral to new technology, the datasheets maintained the conventional outdated formats which leave some of the major components in ambiguity. Making comparisons or predicting actual performance with such datasheets is hardly worthwhile; yet, they could be important reference guide for the potential customers what to expect for the upcoming EO/IR. According to UAS Roadmap 2007-2032 published by DoD, one of the main potential customers as well as a main investor of EO/IR technology, EO/IR is expected to play key roll in solving urgent problems, such as see and avoid system. This paper will examine the recent representative EO/IR specialized in UAS missions through datasheets to find out current trend and eventually extrapolate the possible future trend.

This research aims to find the legal classification of non-profit corporation, to check the pattern of non-profit corporation, to examine thoroughly the present condition of non-profit corporation, and to make a good solution of the problems of non-profit corporation. The findings of this study about the present condition of non-profit corporation are as follows. First, there is an unclear understanding of non-profit corporation and an public fund, Second, a board of directors and a founder control an aim of non-profit corporation freely, Third, there is an unclear management of activity and accounts of non-profit corporation, forth, there is an vague mission of foundation, fifth, some of non-profit corporation supported social welfare project for marketing strategy. and the last non-profit corporation made an competition unnecessarily. On the basis of study result, the researcher make some suggestion for an revitalizing of non-profit corporation. First, it is very important of making a clear mission to manage the non-profit corporation. Second, there is an autonomy and neutrality of non-profit corporation. Third, we make an irrational law better, forth, we make a settled the donation culture. and the last it is necessary of make an foundation for international society.

As we live in real If era, If become a mandatory component for nations and organizations to survive in severe competition. If is also thought of as strategic asset for effective business operations, yet there is no proved statement on the interoperability and system integration which causes serious problem in terms of requirement engineering among current systems. The National Defense Enterprise Architecture Framework is a strategic information asset base, which define the military operation activities for the mission, the information necessary for military operations, the technologies necessary for implementing new technology in response to changing operational needs. It is an integrated model or representation. Information Systems will be evolved by the National Defense Enterprise Architecture framework. The purpose of this framework is to present overall picture of national defense information system domain so that information systems are interoperated, integrated and information sharing is increased among affiliated organization of Defense Military.

In this paper, the mechanism that works by using eight legs is proposed. The walker has eleven bars instead of wheel, it shows a Biologically-inspired movement method. their driving appearance is very similar with creature which walks by its legs. For example, a crab and spider so on. This mechanism has simple style that can expand its size and attach more legs beside. For the competition regulation, we had to find working parts in the science box and some other things that can be found easily in the surroundings only usual material. The mission is making a machine that is enable to pass obstacle and to walk well. This paper followed the rules by regulation.

When operating in confined spaces or near obstacles, collision-free path planning is an essential requirement for autonomous exploration in unknown environments. This study presents an autonomous exploration technique using a carefully designed collision-free local planner. Using LiDAR range measurements, a local end-point selection method is designed, and the path is generated from the current position to the selected end-point. The generated path showed the consistent collision-free path in real-time by adopting the Euclidean signed distance field-based grid-search method. The results consistently demonstrated the safety and reliability of the proposed path-planning method. Real-world experiments are conducted in three different mines, demonstrating successful autonomous exploration flights in environment with various structural conditions. The results showed the high capability of the proposed flight autonomy framework for lightweight aerial robot systems. In addition, our drone performed an autonomous mission in the tunnel circuit competition (Phase 1) of the DARPA Subterranean Challenge.
