  • Currently, 3DTV technologies are being developed as the future services of the HD digital broadcast environment. As one of the various research topics to apply 3DTV technologies to the conventional broadcasting network, methods to configure stereoscopic videos are being studied. In this paper, we proposed a method to broadcast high quality stereoscopic videos based on analysis of a method to add a stereoscopic descriptor to the PMT of MPEG-2 transport streams and a method to transmit stereoscopic videos by the expansion of MPEG-C part 3 which are from precedent studies. The proposed technique maintains compatibility with conventional MPEG-2 transport streams by showing only reference video for models that do not support 3D broadcasting. Therefore, the compatibility between conventional broadcasting and stereoscopic videos should make this method useful when activating 3D services in the communications and broadcasting area

  • First this research starts with agreement that comics is 'the sequential art'. It means that over two sequential panels makes how to recognize the story and this research owes to the connection of forward panel and backward panel. Webtoon, internet comics is also consisted to sequential panels. But only it is different with the publish comics by direction, shape, length and so on. So this research tries to make point of the connection between first panel and second panel. Especially it researches what types of connections between the last panel of first episode and the first panel of second one beyond the connections of panels at only episode. This research treats the types of gutter, 'connection' means to continue the same scenes or 'separation' does to devide the story and shows the new scenes. Weekly webtoon must have a kind of break time. The first panel of next episode should remind of the former story, it means easy technique. Otherwise some first panel don't show the same scenes or story so this study researches 130 artworks from the portal sites; Naver, Daum, mobile comics platform; Lezhin Comics and Toptoon, Corea.

  • In this study, we examined the flux of carbon and water using an eco-hydrological model, Regional Hydro-Ecologic Simulation System (RHESSys). Our purposes were to develop a set of parameters optimized for a well-designed experimental watershed (Gwangneung Research Watershed, GN) and then, to test suitability of the parameters for predicting carbon and water fluxes of other watershed with different regimes of climate, topography, and vegetation structure (i.e Gangseonry Watershed in Mt. Jumbong, GS). Field datasets of stream flow, soil water content (SWC), and wood biomass product (WBP) were utilized for model parameterization and validation. After laborious parameterization processes, RHESSys was validated with the field observations from the GN watershed. The parameter set identified at the GN watershed was then applied to the GS watershed in Mt. Jumbong, which resulted in good agreement for SWC but poor predictability for WBP. Our study showed that RHESSys simulated reliable SWC at the GS by adjusting site-specific porosity only. In contrast, vegetation productivity would require more rigorous site-specific parameterization and hence, further study is necessary to identify primary field ecophysiological variables for enhancing model parameterization and application to multiple watersheds.

  • After analyzing and finding the explaining factors about the "Effect of My Mom's Friend's Son (MMFS Effect)" with online-surveyed data, we introduce this concept into the conventional job search theory to develop it further. We try to estimate its effects on the hazard rate of youth pre-employment duration with some proxy variables such as his/her parents' schooling, living with parents dummy, increasing rate of consumer price index representing the burdens of parents, monthly temporary/daily workers ratio, relative ratio of quarterly 90th percentile urban household income, monthly average wage differentials between the workers of large and small firms, etc. The results confirm us the fact that so called "MMFS Effect" has been effective enough and strengthened up to recently. The conventional job search theory should be extended to be able to introduce the influencing effects of other person's success, for instance MMFS's success, on the job search behavior of youths, too.

  • Economic sanctions and inducements are types of 'policy instruments' based on 'economic tools' to influence other international actors. Ongoing debates on sanctions and inducements have exposed drawbacks for relying on individual case studies. There are some studies in the literature that attempt theoretical analysis of sanctions and inducements, but they are mostly based on rational choice theory. In reality, however, there exist so many cases that cannot be explained by rational choice theory. These are called anomalies or exceptions. The literature introduces specific variables to interpret these anomalies and thus sacrifice the universality of the theory. From this point of view, prospect theory would present an effective tool to analyze economic sanctions and inducements. It is a behavioral economic theory that tries to model a decisions making process in reality. The theory says that people make decisions based on subjective value of losses and gains from an individual reference point, and that people evaluate these losses and gains using heuristics. Thus prospect theory could offer a different frame which has greater explanatory range without adding new variables. As a result of this study, target's losses of 'back down' towards economic sanctions loom larger when the reference point level increases, therefore, the effectiveness of sanctions decreases. However, target's losses of 'stand firm' towards economic inducements loom larger under the same condition of reference point, therefore, the effectiveness of inducements increases. The findings of the paper suggest meaningful implications to the economic policy towards North Korea.

  • This study proposes urban development concept and strategies for Garden City, focused on Solaseado, Yeongam Heanam Tourism-Leisure Type Enterprise City in Korea. Understanding that an essential element of a garden is the endless care performed by gardeners, the Garden City development concept suggests applying this idea to making planned cities by cultivating the potential natural landscape of the site in the long run. The meaning of Garden City can be defined in three aspects; an attitude and process of planning a city, a system for constructing the spatial structure of a city, and city branding. A Garden City is a city structured with the spirit of a garden, a city where open space networks become the urban structure, and a city that builds its identity through the landscape, respectively. From this point of view, the research draws development strategies with spatial design examples to embody the Garden City concept in Solaseado by following three steps; establishing the main urban axes, creating city networks through the conjunction of the axes, and categorizing and systematizing open spaces within the city. Consequently, the study shows an alternative urban planning model that extends the concept of a Garden City while maintaining the intrinsic landscape as an urban resource. In addition, the conceptual master plan of Solaseado will structure the urban landscape and park system according to the Garden City strategies.

  • Furniture world which is closely associated with human life had been constantly developed, but traditional furniture disappeared after modernization almost. The reason lies rather in the importance of the diversity of Western-style furniture pursuing convenience and shapes, than in change of life style meanwhile. The diversity however reached the limit and it made a new advanced role of not only furniture, also design sector in general necessary, and as solution to solve this problem the immaterial value based on Eastern philosophy/mental was suggested in architecture and all around design sector overall as well. It means that the immaterial point which traditional furniture involved should be focused now and furthermore it's emotional and mental value which is more natural and has close relation with human being accordingly could be judged rightly. The reason why traditional furniture had been used since long time is the immaterial tendency which is well harmonized with the surrounding environment rather than the function. To verify this, the present study aimed to analyze not only the basic, also additional function of traditional furniture used in Hanok (traditional Koran-style house) by the inductive method for investigating the additional effects which users felt. Such immaterial role offers the user more convenience besides the original function of furniture and this made it available that furniture dominates the space. As good examples of such roles it was investigated that traditional furniture played meaningful roles like extensional serviceability, variable space, formation & movement of space, expression of grade of rank. That allowed that this study suggested the sustainable design and also the direction of development of interactive function of furniture through the expected effect having been showed in the modern space where the immaterial role of traditional furniture was applied to and the related cases.

  • In this study, we classify the 1000 hPa geopotential height fields around the Korean peninsula through the Kmeans cluster analysis and investigate the occurrence characteristics of each cluster pattern. The 11 clusters are identified as the typical pressure patterns, applying the pattern correlation as a similarity among clusters and the criterion of cluster similarity 0.8, of which three pressure patterns are associated with the extension of Siberia air mass, other three with the latitudes of the longest symmetry axis of North Pacific highs, two with the trough largely under the air mass of Siberia or North Pacific, and the remaining three, the migratory high patterns generally occurring in spring and autumn, are disjointed according to the direction of the longest symmetry axis of highs. The occurrence rate of air masses affecting the Korean peninsula, estimated from the number of occurrence days of 11 pressure patterns, is 55.4% Siberian, 29.3% North Pacific, 12.8% Yangtze-River, 2.5% Okhotsk sea and 68.2% of all these is the continental air masses. The wintertime pressure patterns around the Korean peninsula are nearly contrary to those in summertime, each dominated by the highs extended from the stationary air masses over the Central Siberia and the North Pacific ocean. The migratory highs occur largely in spring and autumn while transferring from the wintertime patterns to summertime patterns, or vice versa. Recently, the occurrence frequency of the highs extended from the North Pacific is on the decrease and while the wintertime pressure patterns occur frequently in spring and autumn, the occurrence frequency of the pressure patterns with trough is on the increase and the migratory highs occur in nearly all seasons.

  • This study targets to recognize needs of adopting public management system in Urban Renewal Project. and to establish evaluation level of public management system using policy evaluation framework for establishing perspective and systemic level. Also, this study constructed basic principles as expanded concept like Public, expertise, participation, rationality, and sustainability based on previous studies and expert opinion. AHP analysis results are following. In case of upper level, post management and continuity are important factors. Also in case of under level, making stable economic system, honest operating system, reducing development costs, local development with self-sufficiency were important factors. through empirical results, the implications are following. First, public management system needs to develop a consistent principle from planning step to post management. Second, it is essential point that continuous retraining between involved people and drawing residents participate in progress activity. Third, when evaluating public management system, it is need that emphasize non-physical factor like conflict issue between stakeholder.

  • Cognitive science attempts to explain human intelligence on the basis of success of artificial neural network, which is called connectionism. The neural network, e.g., deep learning, seemingly promises connectionism to go beyond what it is. But those(Fodor & Pylyshyn, Fodor, & McLaughlin) who advocate classical computationalism, or symbolism claim that connectionism must fail since it cannot represent the relation between human thoughts and human language. The neural network lacks systematicity, so any output of neural network is at best association or accidental combination of data plugged in input units. In this paper, I first introduce structure of artificial neural network and what connectionism amounts to. Second, I shed light on the problem of systematicity the classical computationalists pose for the connectionists. Third, I briefly introduce how those who advocate connectionism respond to the criticism while noticing Smolensky's theory of vector product. Finally, I examine the debate of computationalism and connectionism on systematicity, and show how the problem of systematicity contributes to the development of connectionism and computationalism both.
