The significance of leisure activities is highlighted, and professional baseball games, which featured the 2008 Beijing Olympics gold medal, are very popular. In recent years, along with the revenue from broadcasting, the club has been trying to gain revenue by developing various licensing products and merchandising products. However, sports related products are more advanced than Japanese professional baseball teams in Korea, and there is a lot of revenue from product sales. We want to compare the difference between the two countries sales of their products.

This study explores the evolution of technical innovation over time. It focuses on sectors of the information technology because this industry can be referred to as one of the most dynamic industries of all times. Following evolutionary theorists, we argue that technological change is gradual and that superior firms and technologies are reward by the' selection' environment. In the initial phase of the industry life cycle, technological change is expected to be radical and uncertainty is high. Over time a product or technology is likely to arise which stands out above all other products or technologies. These so-called 'basic designs' serve as sorts of 'technological guideposts' for further developments in the technology. Once a basic design established, technological progress tends to follow consistent paths or trajectories. The cumulative character of technological progress facilitates a rapid expansion of the boundaries of the technology until the natural limits of the technology are approached and technological progress slows down. Following ecological theories, supply-side developments in the industry are described on the basis of five different organizational types. On the basis of this pattern of market and technological evolution we came up with seven basic propositions.

In this paper, we applied the CMRC to a resonator to improve the harmonic characteristic of VCO. The CMRC filters have some advantage. It is a small size as well as easy to manufacture than PBG, DGS and other filters. This paper was proposed by using CMRC for a VCO. The second harmonic of -42.83 dBc and the phase noise at 100 kHz offset of -95.83 dBc/Hz was achieved, respectively. The VCO has better second harmonic character by 15.73 dB and phase noise by 31.13 dB in case of CMRC applied behind a resonator than CMRC used as a resonator.

This paper introduces three efficient frame selection schemes to reduce the computation complexity for the multi-reference and variable block size Motion Estimation (ME). The proposed RSP (Reference Selection Pass) scheme can minimize the overhead of frame selection. The MFS (Modified Frame Selection) scheme can reduce the number of search points about 18% compared with existing schemes considering the motion of image during the reference frame selection process. In addition, the TPRFS (Two Pass Reference frame Selection) scheme can minimize the frame selection operation for the variable block size ME in H.264/AVC using the character of selected reference frame according to the block size. The simulation results show the proposed schemes can save up to 50% of the ME computation without degradation of image Qualify. Because the proposed schemes can be separated from the block matching process, they can be used with any existing single reference fast search algorithms.

Recently, according to the development of ubiquitous computing, the u-GIS which not only used in u-Transport, u-Care, u-Fun, u-Green, u-Business, u-Government, and u-City but also used to provides various spatial information such as the location of user is being the core technology of the ubiquitous computing environment. In this paper, we implemented an mobile spatio-temporal Query Processing Systems for handling the Spatio-Temporal Data in mobile equipment.The mobile spatio-temporal Query Processing Systems provides the spatio-temporal data type and the spatio-temporal operator that is expanded by the spatial data type and the spatial operator from OepenGIS "Simple Feature Specification for SQL". It supports arithmetic coding compression techniques that is considered with a spatio-temporal data specific character. It also provides the function of data cashing for improving the importation and exportation of the spatio-temporal data between a embedded spatio-temporal DBMS and u-GIS server.

This is part of a study on the origin of modernist forms and settings. Forms in Modern Architecture are totally new as though they seemed to be originated from some remote culture. Archaeological studies and Laugier's primitivist attitude to the classical architecture provided a way leading, in the end, to pure structures and abstract forms. An application of the classical elements was combined with the ultimate image of nobility, simplicity and rationality. What the seventeenth and eighteenth century theorists realized in the ruines of the classical structures were not the ones with their original organic vitality but the deteriorated, naked and abstracted ones. The essence of the classical structures has been the one of the main references of the modern white architecture. Ration and Nature were the quintessential terms in the design process of the Enlightenment architects of the late eighteenth and nineteenth centuries as they were in the twentieth century architecture. Pure geometric and symbolic forms were new inventions for the new revolutionary age after the development of architectural Styles, successive until Baroque and Roccoco, ceased to go on to the next phase. Many of their buildings appeared so modem in character, for they were omitted all but the essential structure and decoration. Other sides of rationality in the pre-modern age were evolved in terms of the paradigmatic research and the logic in structure. Durand developed a systematic typological approach to the forms. Geometry was the basis of his designs and his illustrations resembled endless simple geometrical problems. One of the other rational approaches was mainly developed by Viollet-le-Duc. To him, Gothic architecture was the model in which each members functioned actively and exerted counterpressure and the Middle Ages invented new fantastic forms. The several ways of rational approaches in architecture were led to the 'tabula rasa' planning in modern architecture. Nature was remained untouched and not deformed as Ledoux's houses in the $H{\hat{o}}tel$ de $Th{\acute{e}}lusson$ were setted on informal gardens. It is part of the modem image that Nature flows or interpenetrates through the white prisms of the strictest classical purity and machines.

This experiment was conducted to compare the productivity of five silage corn varieties. Corn varieties were Pioneer 3144(P 3144), 3160(P 3160), 3282(P 3282), 3352(P 3352) and Suweon 19(S 19) and were seeded on May 2 and harvested on August 15. Ratios of stalk, leaf and ear, chemical composition and yields of nutrients were investigated in respective corn part. Experimental design was accepted by Latin square arrangement with five replicates and each plot had twenty two plants. The results obtained were as follows: 1. Crude portein, crude ash and nitrogen free extract(NFE) contents of whole plant ranged from 6.32 to 7.18%, 5.16 to 7.43% and 52.62 to 57.90%, respectively, and there were no significant(P>.Ol) differences between varieties. Crude protein and NFE content were the highest in ear between corn parts. 2. Crude fiber conent of whole plant ranged from 18.98 % to 24.01 %, and was the highest in suweon 19 and the lowest in P 3352(P<.01). Crude fiber content was the highest in stem and the lowest in ear, However, crude fat content(2.03-3.66 %) vice versa. 3. Yields of organic matter, crude protein, crude fat, NFE and TDN per 10a were the greatest(P< .01) in P 3282, however crude fiber yield was the highest(P<.Ol) in P 3352. 4. Ratios of different part to total dry matter yield ranged from 12.7 %(P 3352) to 17.8 %(P 3160) for leaf, 44.5(P 3352) to 66.9 %(P 3160) for stem and husks, and 16.9 %(P 3282) to 42.8 %(P 3352) for ear, and there were significant differences between corn varieties(P<.Ol). Consequently, P 3352 has the greatest nutrient yields, particularly by ear, and P 3282 has a great nutrient yield by stem. This result suggested that could be appear a better character of silage corn by hybridization of this two corn varieties.

In this paper, we propose a robust duality of CNN(Du-CNN) method which can classify the target and clutter in coastal environment for IR Imaging Sensor. In coastal environment, there are various clutter that have many similarities with real target due to diverse change of air temperature, water temperature, weather and season. Also, real target have various feature due to the same reason. Thus, the proposed Du-CNN method adopts human's multiple personality utilization and CNN technique to learn and classify target and clutter. This method has an advantage of the real time operation. Experimental results on sampled dataset of real infrared target and clutter demonstrate that the proposed method have better success rate to classify the target and clutter than general CNN method.
