  • Asian Journal of Innovation and Policy (AJIP) would like to introduce an interview section on innovations, innovators, and entrepreneurs if possible in every issue. The interviews introduced will be selected not based on a journalistic view, but rather by its theoretical or practical implications. This issue will introduce an entrepreneur who was a key engineer, Chief Technology Officer (CTO), and CEO of Samsung Electronics, in addition to being the Minister of ICT in the Korean government. Currently, he is the CEO of an investment company. His success was tied to the success of semiconductors at Samsung Electronics, which became the world leader, leading some to even call him "the god of semiconductors". This interview resurrects the debates on the mode 2 society and the role of education in entrepreneurship.

  • The purpose of this study was to develop a period analysis algorithm for detecting new variable stars in the time-series data observed by charge coupled device (CCD). We used the data from a variable star monitoring program of the CBNUO. The R filter data of some magnetic cataclysmic variables observed for more than 20 days were chosen to achieve good statistical results. World Coordinate System (WCS) Tools was used to correct the rotation of the observed images and assign the same IDs to the stars included in the analyzed areas. The developed algorithm was applied to the data of DO Dra, TT Ari, RXSJ1803, and MU Cam. In these fields, we found 13 variable stars, five of which were new variable stars not previously reported. Our period analysis algorithm were tested in the case of observation data mixed with various fields of view because the observations were carried with 2K CCD as well as 4K CCD at the CBNUO. Our results show that variable stars can be detected using our algorithm even with observational data for which the field of view has changed. Our algorithm is useful to detect new variable stars and analyze them based on existing time-series data. The developed algorithm can play an important role as a recycling technique for used data

  • In the field of augmented reality technologies, commercial optical see-through-type wearable displays have difficulty providing immersive visual experiences, because users perceive different depths between virtual views on display surfaces and see-through views to the real world. Many cases of augmented reality applications have adopted eyeglasses-type displays (EGDs) for visualizing simple 2D information, or video see-through-type displays for minimizing virtual- and real-scene mismatch errors. In this paper, we introduce an innovative optical see-through-type wearable display hardware, called an EGD. In contrast to common head-mounted displays, which are intended for a wide field of view, our EGD provides more comfortable visual feedback at close range. Users of an EGD device can accurately manipulate close-range virtual objects and expand their view to distant real environments. To verify the feasibility of the EGD technology, subject-based experiments and analysis are performed. The analysis results and EGD-related application examples show that EGD is useful for visually expanding immersive 3D augmented environments consisting of multiple displays.

  • Landscape Style would take various influences in general. In that of Korean Palaces religious thinking has been caused he most important factor. This conceptual attitude has been derived from Confucian philosophies and the doctrines of Taoism, the realm of ideas that had constituted the schema of culture through long times in the Orient. This paper has dealt with the influences of one's outlook on the universe, antropocentricism, and on the relationships of man and nature in those two major teachings upon the landscape style of palaces in Chosun Dynasty. The Confucian philosophies and the doctrines of Taoism in Taosim in palaces would be summarized as followings: 1. The composition of exterior spaces had been understood as a place for moral training and political morality in the world view of Confucious. 2. The view point on court circle with plants and trees had directed to the influences of beauty upon the human spirit, and it is clear in naming attitude. 3. The composition type of void and solid in palaces would focused on the completion of Confucian thoughts totally, and the method of a unit space is same. 4. The double symbolic ideas could be find out in the components of exterior space; one is Confucian in phenomena, the other is Taoism in meaning. This can be cleared in Pangji(方池), layout of natural features, and in planting methods. As a conclusion, the common spiritual base in landscape architecture of Korean old palaces can be understood as two major thinkings; Confucian philosophies and the doctrines of Taoism.

  • This study aims to analyze the types of occupations that are presented through the illustrations in the elementary school textbooks specifically designated by the government, from a perspective of a digital world.. Types of occupations were analyzed from a perspective of digital world by analyzing the illustrations presented in Korean language, social studies and ethics textbooks of elementary school year 3~6. Occupations that would disappear in future were compared and analyzed from a point of view of a report, "The Future of Employment: How susceptible are jobs to computerisation?". As a result of the analysis, it was confirmed that the occupations presented in the textbook were not reflecting the change of society and occupations, and there was absolutely no reflection of the times at all that highlights SW. This study has a significance for proposing directivity regarding writing of new textbooks at a current situation of new textbook work being processed, based on the 2015 amended curriculum.

  • Nowadays, the international economic environment has been improved by the World Trade Organization based on UR trade negotiation. In such state, the international commerce cooperation, which means trade liberalization through relaxation or abolition of customs and noncustoms harrier, is necessary a country's policy for overseas strategy. To the view point of international commerce order, there co-exist the globalism represntatived by GATT/WTO and the regionalism operated by European Community including 15 countries, or North American Zone with canada, Maxico. The former expands the trade liberalization through the most favoured nation treatment of WTO among whole world nations and the latter takes the differential trade policy to other countries. For extreme dependence on foreign natural resources and raw materials, Our country should strengthen it' comming prospect for the world economy. To put it more concrete, We must enforce in advance the legal basis of convention and norm which in adopted by WTO. Also we are desirable to cooperate with Asia and pacific economy area or APEC. Finally, under the direction of international commerce environment and world economy, we must take the commerce cooperation in global order considering the tendency of regionalism and bloc economy.

  • Environmental conservation has become one of the greatest concerns of all the people in the world. This issue is related to wood utilization in two major view points such as carbon dioxide emitted by the use of manufacturing energy and absorbed during the growth of trees. Wood construction materials require less manufacturing energy, which, in turn, means less carbon dioxide emission. In addition, wood keeps absorbed carbon in itself as far as it is not burnt. Therefore, wood is environmentally superior to other materials in terms of potential effects on atmospheric carbon dioxide. As examples of the environmental effect of wood utilization, the following two results were obtained: 1) If wood construction becomes popular in Korea as in Japan, more than 24% of carbon dioxide emission during construction of residential housings can be reduced: and 2) If aluminum windows are substituted by wood windows, more than 19% of carbon dioxide emission can be reduced. If the principle of "cut and plant" is kept well, wood is the best construction material for environmental protection as well as human residence.

  • Our networked world has been growing exponentially fast. The explosion in volume of machine-to-machine (M2M) transactions threatens to exceed the transport capacity of the networks that link them. Therefore, it is quite essential to reconsider the tradeoff between using many data sets versus using good data sets. We focus on this tradeoff in the context of the quality of information aggregated from many sensors in a noisy environment. We start with a basic theoretical model considered in the famous "CEO problem'' in the field of information theory. From a point of view of large deviations, we successfully find a simple statement for the optimal strategies under the limited network capacity condition. Moreover, we propose an open problem for a sensor network scenario and report a numerical result.

  • In this paper, we propose a system which estimates Manhattan coordinate systems for urban scene images using a convolutional neural network (CNN). Estimating the Manhattan coordinate system from an image under the Manhattan world assumption is the basis for solving computer graphics and vision problems such as image adjustment and 3D scene reconstruction. We construct a CNN that estimates Manhattan coordinate systems based on GoogLeNet [1]. To train the CNN, we collect about 155,000 images under the Manhattan world assumption by using the Google Street View APIs and calculate Manhattan coordinate systems using existing calibration methods to generate dataset. In contrast to PoseNet [2] that trains per-scene CNNs, our method learns from images under the Manhattan world assumption and thus estimates Manhattan coordinate systems for new images that have not been learned. Experimental results show that our method estimates Manhattan coordinate systems with the median error of $3.157^{\circ}$ for the Google Street View images of non-trained scenes, as test set. In addition, compared to an existing calibration method [3], the proposed method shows lower intermediate errors for the test set.
