An improved model of 'use' or 'region' districting(or regional zoning) scheme has been proposed. GIS based prototype model of managing the semi-agricultural region is implemented in a PC based platform focusing the Yongin, Kyonggi-Do area. Throughout the process of users' requirement analysis, database design, and user interface design, it has been shown that the integrated system may shed light on the prospective usage by the city or county government officials regardless of the short functionalities and user interface. This study aims first at identifying the needs in the area of districting at local level and at suggesting a basic framework of database design and system implementation in regard to region districting. The ARC/INFO, ArcView/Avenue based PC-based decision supports system presented herein is hoped to be supplemented with the inclusion of time factor in its database to cover and reflect the temporal variations associated with the plans.

Face classification has wide applications in security and surveillance. However, this technique presents various challenges caused by pose, illumination, and expression changes. Face recognition with long-distance images involves additional challenges, owing to focusing problems and motion blurring. Multiple frames under varying spatial or temporal settings can acquire additional information, which can be used to achieve improved classification performance. This study investigates the effectiveness of multi-frame decision-level fusion with photon-counting linear discriminant analysis. Multiple frames generate multiple scores for each class. The fusion process comprises three stages: score normalization, score validation, and score combination. Candidate scores are selected during the score validation process, after the scores are normalized. The score validation process removes bad scores that can degrade the final output. The selected candidate scores are combined using one of the following fusion rules: maximum, averaging, and majority voting. Degraded facial images are employed to demonstrate the robustness of multi-frame decision-level fusion in harsh environments. Out-of-focus and motion blurring point-spread functions are applied to the test images, to simulate long-distance acquisition. Experimental results with three facial data sets indicate the efficiency of the proposed decision-level fusion scheme.

Recently, many research works are focusing on DVC (Distributed Video Coding) system for low complexity encoder. However the feedback channel-based parity bit control is a major cause of the high decoding time latency. Spatial and temporal correlation is high in video and, therefore, the statistical property can be applied for the parity bit request of LDPCA frame. By introducing frame adaptive parity bit request estimation method, this paper proposes a new method for reducing the decoding time latency. Through computer simulations, it is shown that the proposed method achieves about 80% of complexity reduction, compared to the conventional no-estimation method.

Marine sponges are a rich source of highly diversified bioactive compounds. These medicinally valuable molecules represent extreme physiological and ecological functions in sponges, more presumably involving in the resistance to the feeding by other marine organisms like fish and fouling by barnacles, bacteria, fungi, etc. This feature of attaining resistance made sponges as successful poriferans that possess an impressive array of biological properties ranging from antimicrobial to anticancerous activities. The diversified bioactive principle of sponges might be due to their spacio-temporal distribution and although, the gateway for exploiting the sponges for isolating these distinct, potential molecules is open, suitable technical and methodological approaches are yet to be implemented in order to bring the sponges as successful pharmaceutical leads in the field of marine biotechnology. Despite of the identified difficulties of marine sponge research from past few decades, one should concentrate not only on the basic and applied technical/methodological considerations, but also on the novel strategies like in vitro sponge cell, fragment and whole sponge culture; sponge symbiont cell culture; in situ and ex situ sponge cultivation; and sponge bioreactors and metagenomic approaches, for the successful exploitation of marine sponges towards the novelty in sponge biotechnology. The present review narrates the pros and cons of the nowadays-marine sponge research by focusing on the suggestive ecobiotechnological approaches, based on the latest studies for feasible ecological exploitation and biotechnological application of sponges from the sea.

Reading disability (dyslexia) refers to an unexpected difficulty with reading for an individual who has the intelligence to be a much better reader. Dyslexia is most commonly caused by a difficulty in phonological processing (the appreciation of the individual sounds of spoken language), which affects the ability of an individual to speak, read, and spell. In this paper, I describe reading disabilities by focusing on their underlying neurobiological mechanisms. Neurobiological studies using functional brain imaging have uncovered the reading pathways, brain regions involved in reading, and neurobiological abnormalities of dyslexia. The reading pathway is in the order of visual analysis, letter recognition, word recognition, meaning (semantics), phonological processing, and speech production. According to functional neuroimaging studies, the important areas of the brain related to reading include the inferior frontal cortex (Broca's area), the midtemporal lobe region, the inferior parieto-temporal area, and the left occipitotemporal region (visual word form area). Interventions for dyslexia can affect reading ability by causing changes in brain function and structure. An accurate diagnosis and timely specialized intervention are important in children with dyslexia. In cases in which national infant development screening tests have been conducted, as in Korea, if language developmental delay and early predictors of dyslexia are detected, careful observation of the progression to dyslexia and early intervention should be made.

A mega sport event as the globalization phenomenon is not only the symbol of the process of modernization but also the vehicle to upgrade global power and hold a dominant position in the world competition under the post-industrial era. This study notifies the role of mega sport events as a strategy for urban innovation in the context of global and local. Comparing the different roles of mega sport events between developing countries and developed countries, we intend to answer two questions: 1) what explains the nature and role of mega sport event, and 2) what are the major evidences of the transition in the globalization era. The conceptual framework, based on the temporal and spatial perspective, provides the mechanism through which the strategy for urban innovation has been changed from 'motivation for modernization' to 'rethinking of localization.' Focusing on the case of Seoul, we also compare major issues between two phases: role of agent, urban form, and urban development. Finally, this study sheds light on the concept of 'glocalization' which means the convergence of globalization and localization; and suggests the roles of (local) agent for hosting mega sport events.

This study is an attempt to construct a basic framework of analysis about China's political and economic influence on Southeast Asia through traditional Sinocentrism, anti-colonial nationalism, Cold War socialism and post-Cold War capitalism. As to the historical status of Southeast Asia vis-a-vis external forces such as India, China and the West, the colonial discourse tends to put excessive emphasis upon its dependence, and the posy-colonial discourse upon its autonomy. However, this study elucidates the political and economic interactions between China and Southeast Asia in a dynamic perspective, focusing on their reciprocal interactions beyond the essentially static dichotomy of autonomy and dependence. Chinese influence on Southeast asia can be divided into active and reactive one, with the former referring to direct and intended consequences and the latter to indirect and unintended consequences. In the historical process of active and reactive influence, both China and Southeast Asia were fundamentally proactive actors. Thus, the autonomy or dependence of Southeast Asia is just a question of relative one, with its actual extent and degree varying with specific spatial and temporal conditions.

The objective of this paper is to explore Jim's itinerary journey in terms of both Girald's concept of triangular desire and Derrida's concept of event. According to the Girard's mimetic desire theory, human being's desire is not spontaneous like Romanticism thought, but mimetic to the mediator between the subject and the object. Thus there is no romantic desire understood as one's own desire except mimetic desire. In this regard, mimetic desire is compatible with the conception of Derrida's thinking of an event that is resistant to its absolute singularity. Because both mimetic desire and event cannot be defined by the fact of each spatio-temporal specificity, they can not be understood by a traditional metaphysics of presence. In this paper, by using Girard's concept of mimetic desire theory, I showcase why the tragic journey of Jim's telos as a mythic quest for his romantic ego(ipse) cannot help but face his death and by using deconstructive thinking of iterability, this paper analyzes why Jim's romantic ego imitated by the mimetic desire through a mediator cannot be encountered happily with his ipseity until his end. As a victim of triangluar desire, Jim's romantic ego is nothing but a notion of an ipsiety that has been defined in terms of presence central to metaphysics. This paper also makes an attempt to re-interpret some articles contaminated with post-colonial perspectives from Derridean views with deconstructive rigorous reading to those papers to uncover an essential ground of presence.

This note summarizes the application of zooplankton indices for water quality management and estimation based on main research topics of articles focusing on wetland ecosystems, topics that are remained poorly investigated in S. Korea. The aquatic ecosystem-based consists of indices that respond to different target environmental factors, including environmental disturbance. Among the major indicator species and biota, we reviewed that management strategy for the wetland environment has to be focused more on small-sizes, in terms of zooplankton ecology and indices. The ecology of zooplankton communities in freshwater ecosystem has been the focus of an increasing number of studies since 2019, and considerable progress has been made in understanding the major mechanisms involved in regulating their abundance, diversity and spatio-temporal patterns. Even though studies on the freshwater ecosystem in Korea have a long history, a few of studies on zooplankton biota were conducted at wetlands. We suggested the candidate zooplankton indices proposed by the U.S. EPA and EU to suit Korean conditions. In the step of selecting metrics, the best available metrics are species-related variables, such as composition and abundance, as well as richness and diversity. Overall, in spite of several limitations, the development of a plankton-based multivariate assessment method in Korea wetlands is possible using mostly field research data. Later, it could be improved based on qualitative metrics on zooplankton, and with the emergence of further survey data. The present information can be used as basic information for researchers who are dealing with aquatic environments and its interaction with organisms.

At present, Korean one-person households have been continuously increased in spite of the reduction of total population. The increasement of one-person household has become a social and institutional issue. It is necessary to response socially and economically to not only changes of housing demand but also the disadvantaged classes such as the socially weak and single elderly household from the national level. In this respect, this research examined the spatial distribution (such as the increasing area, high-density area, and majority area) of one-person household with census data in the city of Busan. The clusters of one-person households were selected by focusing on the spatial distributions by time series changes of 2000, 2005, and 2010 and considering their housing characteristics. In terms of policy efficiency, the clusters of one-person households to be supported by priority were derived by analyzing the census data from 6066 output areas in the city of Busan. As a result, lots of one-person households of juniors were distributed around the university town, office facility, and station service area. Lots of one-person households at middle-aged class were distributed in Busan's original downtown and mountain-side road. Generalizing these characteristics, cluster analysis was conducted. As a result, one-person household dense area in Busan could be classified into four types. This research should be utilized as a counterplan for increasing the housing demand of one-person household or basic data for supporting small housing supply policies in the future.
