Traditional village forests called Dangsan forests represent unique cultural landscape as a national cultural asset in Korea with a history of more than several hundred years. Cultural heritage can retain their value when they are fully sustained their authenticity and management scheme. The Dangsan forests established in a large area have been designated as a natural monument by Cultural Heritage Administration. Small scale Dangsan forests, however, are not introduced to the public and on the verge of disappearance. Dangsan forests have a value as a core landscape element in rural landscapes of Korea. The two villages at Ijeon-ri, Cheongsong-gun have small Dangsan forests where Dangsan ritual is performed. At one of the villages, there is Jusanji Reservoir designated for Scenic Site # 105, from which the water is used for growing crops. In this study, the landscape characteristics of the Dangsan forests were investigated including rice paddy field, stream, and the Jusanji Reservoir. A conservation measure of rural landscape for sustainable management scheme was suggested by designating 'Conservation area of agricultural landscape ecology'. Dangsan forests, especially where they are in small scale like those of Ijeon-ri, tend to be neglected. The Dangsan forests ought to be recognized for their value and by providing a management scheme including neighborhood elements such as farm fields and streams they can be revitalized to be core areas for conservation of rural landscape.

Textile fashion industry is a core foundation industry, having the majority of companies with 10 or more workers, in Northern Gyeonggi Province. however the industry is mostly comprised of small unit-stream enterprises, orders are greatly reduced due to lately accelerated overseas expansion of medium/large-sized vendors and the growth-inhibiting vicious circle has being set in, as this situation causes the reduction of investment. For resolving the problems, this study proposes required political factors and concrete policy proposals by designing AHP research model(4 layers and 36 elements), based on grasp of the transitional aspect of industrial scale and business environment through analysis of various industrial statistics, preceding research such as related literature search and (industrial/academic/R&D/government) specialist opinion investigation, and then calculating relative importance and priority of each factor(element) within each layer. And for raising usefulness and availability of the research result by concretely suggesting the vision, strategies, core tasks and detailed projects in which the research model and deduced result are reflected.

For the scientific and systematic study of sediment deposits along Yeongsan river, total 13 core samples were taken from Yeongsan river. The thickness of sediment deposits is 22.0m at YS 1, 20.0m YS 2, 18.5m YS 3, 12.0m YS 4, 3.0m YS 5, 5.5m YS 7, 3.0m YS 8, 5.9m YS 9, 5.0m YS 10 on main stream of Yeongsan river. The thickness of deposit is increasing from upstream to downstream. The composition of sediments dominates sandy gravel on the upstream and the lower part on the downstream, and mud deposits of $11m{\sim}16m$ thick on the upper part of on the downstream(YS 1, YS 2, and YS 3). Contents of organic carbon and calcium carbonates occur being contrary to each other toward upstream. The content of organic carbon increases upstream, that of calcium carbonates decreases. According to size analysis of sediment, the content of gravel increases and mud decreases from downstream to upstream. Sediment deposits can be divided into two types whether gravel is or not. But this boundary is clear in the downstream(YS 1$\sim$YS 4) but is vague in the upstream. The result of this study could be provided engineering, environment, and architecture with geological background as the essential basis.

AMS radiocarbon dates indicated that Eurimji reservoir, located at Jecheon City, Chungbuk Province, has been formed during the late Holocene Epoch. The sedimentary sequence at bottom reveals histories in hydrology, climate conditions and past vegetation dynamics. Ages controlled sedimentological and palynological analyses on ER 3-1 Core contribute to reconstruct paleoclimate and past hydrological conditions. These analyses suggest that lower interval (307.5m~309.5m elevations) of the ER 3-1 Core was deposited in stable from 1,920 yrBP to 1,420 yrBP, but upper layer sediment above these elevations was composed of reworked sediments during the pre and post 2,000 yrBP. Pollen assemblage indicates that watershed vegetation of the Eurimji reservoir, during the period of 1,920 yrBP~1,420 yrBP, was closely comparable to modern vegetation dominated Pinus and Quercus mixed vegetation. Also, riparian including Alnus, Fraxinus and Salix were inhabited along the banks of stream, and aquatics such as Typha, Nymphaea and Persicaria flourished at shore of the reservoir. According to cultural chronicle, it infers that the Eurimji reservoir was formed from the Bronze Age to the Iron Age or the beginning of ancient society. An integrated data suggested that Quercus-Pinus-Abies mixed forest flourished under cool and dry climate conditions during 3,200 yrBP~200 yrBP.

The roles of the characters of 3D animation Toystory3, which was released in 2010 and achieved worldwide success, can be classified into typical, simple and easy-to-understand roles such as hero, villain, princess, and assistant. However, the process, in which each character's role is finally recognized by the audience, is embodied in a very colorful and exquisite manner and makes the curiosity of the audience continue effectively. The stream of the diverse role changes of the characters of Toystory3 is represented through "visual rhythm of the lighting design" and such rhythm can be confirmed most clearly in the digital colorscript stage. This researcher analyzed the characters' role changes in the work based on Propp's folktale character analysis theory, and extracted the core scenes that lead to inference, doubt, performance, reinforcement by character in order to grasp how the audience gasps major characters' role changes. The visual differences of the lighting design, which the four core scenes of each character show, were represented in graph and analyzed, and the results showed that the changes that one character has constituted rhythmical, visual contrast gradually and the rhythms of each independent character achieve visual contrast and harmony each other like the voice part of polyphony. This researcher calls this "the visual counterpoint of character's changing" and derives the conclusion that a dual visual counterpoint is hidden in the character production of the full-length animation Toystory3. Along with this, this researcher proposes the production of full-length animation that actively utilizes constructive aesthetics.

Spraying method from the paddy-field levee is known to give insufficient penetration of the spray droplets to the rice stem of the densely grown plants, which is generally encountered at the last stage of rice growth. This study was intended to investigate the spraying system to solve this existing problem. As an approach, it was attempted to develop the boom-with-nozzle, between-the-row application system. Several types of nozzles and their different arrangements in the boom were tested in the field to measure the penetration-reaching distance and the uniformity of spray droplet distribution. The results of the study are summarized as follows: 1. Field experiments by the spraying method from the paddy-field levee showed to have practically no penetration of the spray droplets to the portion of the plant stem with the normal flow volume generally applied and thus need for improving present spraying method. 2. It was found that, considering both the uniformity of the spray droplet distribution and performance rate, the most efficient type of nozzle in the between-the-row boom-type spraying system was one that has core-insert hollow-cone with some clearance between the cone and tip. 3. When tested by applying the spraying method of between-the-row, the nozzle pressure did not affect the uniformity of spray droplet distribution. However, the nozzle pressure had a positive effect on the penetrating-reaching distance of the facing side of the rice stem and did not affect much on that of the opposite face of the stem. It was also found that the maximum pressure to affect the penetration-reaching distance was about $10kg/cm^2$. 4. The uniformity of the spray droplet distribution in the between-the-row system was greatly affected by the height and orientation of the nozzles in the boom. Based on experimental work for the different type of the boom-with-nozzle arrangements, it is recommended that the position of nozzle is set at about 0.45 m above the ground and two nozzles in the boom are oriented to be faced with each other with some angle such that the droplet stream from the nozzle would not directly face with each other.

A numerical analysis of the effect of the position of a circular cylinder in a $45^{\circ}$ tilted enclosure on natural convection in the enclosure is presented. The location of the cylinder is changed between -0.4 and 0.4. The Rayleigh number is varied between $10^3$ and $10^5$. The effect of the location of the cylinder on natural convection in the enclosure is analyzed by the isothermal line, stream line, and surface-averaged Nusselt number. The flow and heat transfer characteristics are independent of time in the range of the Rayleigh number and cylinder location that is considered in this study. The surface-averaged Nusselt number of the cylinder and enclosure increases as the cylinder gets closer to the wall of the enclosure.

One of the critical themes in the language acquisition is its exposure to linguistic environments. Linguistic environments, which interact with infants, include not only human beings such as its parents but also artificially crafted linguistic media as their functioning elements. An infant learns a language by exploring these extensive language environments around it. Based on such large linguistic data exposure, we propose a machine learning based method on the cognitive mechanism that simulate flexibly and appropriately infant's language learning. The infant's initial stage of language learning comes with sentence learning and creation, which can be simulated by exposing it to a language corpus. The core of the simulation is a memory-based learning model which has language hypernetwork structure. The language hypernetwork simulates developmental and progressive language learning using the structure of new data stream through making it representing of high level connection between language components possible. In this paper, we simulates an infant's gradual and developmental learning progress by training language hypernetwork gradually using 32,744 sentences extracted from video scripts of commercial animation movies for children.

The Seoul Housing Corporation pronounced a design competition for Eunpyeng New Town District 2 in March of 2005. The authors collaborated on this design and won rot prize. Design guidelines of this competition were to make environmentally sustainable design, to develop as a resort site and cultural place for everyday life of residents, to link with green fabric of the district, and to elevate positive image and identity of Eunpyeng New Town district by creating a attractive landscape. The authors developed design concept and strategy within the guidelines and site conditions. The environmental setting of this site was characterized by mountain to the rear of the site with a stream passing through the district and the front of the site. This is the most important condition for the location principle of residence in Fung Shui theory. Therefore, the schema of the design was introduced by Fung Shui and Chi of place. To evolve design concept, we reinterpret the Fung Shui and Chi in the site combining with modem landscape design strategy, so that good place making could bring about well-being life of residents. By doing that, design concept of the proposal evolved as follows: 'fullness of comfortable life', 'adaptation of nature', 'inspiration of natural force'. This design approach is critical reevaluation of regional characters employing modem strategy. It is a conscious strategy of critical regionalism as distinguished from the traditional site oriented approach. The following are some of the major features in the design: green network and water recycle system in the site, promenade of forest with the experience nature, link to community core, theme gardens with plants having strong fragrances, terrace gardens with different level of housing type, playgrounds and resting places with many types, human scale facilities for residents.

It becomes more and more more important for the storage that supports high speed recording and stable access from network environment. As one field of basic science which produces massive astronomical data, VLBI(: Very Long Baseline Interferometer) is now demanding more data writing performance and which is directly related to astronomical observation with high resolution and sensitivity. But most of existing storage are cloud model based for the high throughput of general IT, finance, and administrative service, and therefore it not the best choice for recording of big stream data. Therefore, in this study, we design storage system optimized for high performance of I/O and concurrency. To solve this problem, we implement packet read and writing module through the use of libpcap and pf_ring API on the multi core CPU environment, and build a scalable storage based on software RAID(: Redundant Array of Inexpensive Disks) for the efficient process of incoming data from external network.
