The purpose of this research is placed on the development and application of environmental play programs for elementary school students their utilizing the neighborhood learning gardens in their districts to find its effectiveness. The research questions drawn to attain the purpose of the research are as follows. Initially, analyze the contents related to the plant appearing in the textbooks of wise life, science and practical arts of the 7th elementary school curriculum. Secondly, develop a plant utilizing environmental play program targeted towards the 4th grade elementary school students with the results of the textbook analysis as the foundation. Third, apply the plant utilizing environmental play program into the classroom to verify its effectiveness. Based on the conclusion of this research, the following is to be proposed. First, the revitalization of regional environmental education utilizing the various surroundings of the region is essential. Also, the current method of education, which is focused on theoretical knowledge, and being operated in most of the schools need to be changed over to diverse environmental education programs that are linked with the region. For this, an internet based database, information sharing and exchange program centralized around the regional environmental education center needs to be prepared. Moreover, since this research had developed an environmental play program utilizing plants that focused on the 4th grade elementary school students to verify its effectiveness, the development for environmental play programs dealing with various themes for each grades is required. Lastly, although this research has verified the effectiveness in the variables of ecological knowledge, environmental susceptibility, environmental attitude, environmental concern, environmental function and responsible environmental behavior amongst the variables of environmental literacy but there requires a succeeding research considering the variables that haven't been included in this research.

Since 2008, a communal child care and 'Family Pumasi' program have been conducted as a pilot project for the Healthy Family Support Center. These programs have been positioned as a step toward a family friendly community project. For the Healthy Family Support Centers, a family friendly community project is an essential program as a part of the policies in response to the country's low fertility. However, the people in charge face difficulties, because they do not have much experience in such projects. This study attempted to explore the preferences regarding interior and exterior apartment spaces, and neighborhood environment to provide information about how to better implement a family friendly community program. For this purpose, data were collected from 418 housewives who are apartment dwellers in Daejeon city. The results were as follows; first, the person in charge must consider child care facilities, culture, and sports centers in order to start building a community lifestyle. Second, people with relatively low levels of education and short terms of residence are more deeply motivated by community lifestyle compared to others. Third, families with their first young child showed much interest in communal child care facilities. If the people in charge can motivate and encourage such residents to be engaged in family friendly community projects, the project will effectively progress.

With the introduction of the 40 hours workweek system, an intensive discussion was made among relevant departments. Building facilities does not necessarily guarantee more leisure activities and higher satisfaction for the public. It is essential to draft at the trend of leisure policy in Japan and learn from the experiences to set the policy direction best fitting future changes in Korea, as Japan has gone through comprehensive changes ahead of us. With this understanding, this study analyzed key leisure policies of Japan and examined the trend of changes of time. The followings are the findings of the research. First, Japan's leisure policies could be categorized into five stages and six terms. Second, leisure policies in Japan are being established as a local welfare system, not in the context of industrial perspective, to help people in local community. This is to make voluntary move by eliminating the factors that restrict social demand with an effort to expand leisure time and to secure and enhance access to leisure space. Third, Neighborhood leisure space has taken the center stage, in an effort to seek solutions to the issues of improving space utilization, restoring local community and encouraging participation of local residents. The conclusion drawn from the research is as follows. It is required to recommend the use of the specific term 'leisure' for leisure policies in Korea and for leisure space policies in Korea that are now facing sociocultural challenges similar to the ones emerging in Japan, measures are required to improve physiological access of local residents including information promotion, lifetime education and relationships enhancement along with the establishment of neighborhood leisure space.

In this paper, we propose a technique for retrieving images using spatial color correlation and texture characteristics based on local fourier transform. In order to retrieve images, two new descriptors are proposed. One is a color descriptor which represents spatial color correlation. The other is a descriptor combining the proposed color descriptor with texture descriptor. Since most of existing color descriptors including color correlogram which represent spatial color correlation considered just color distribution between neighborhood pixels, the structural information of neighborhood pixels is not considered. Therefore, a novel color descriptor which simultaneously represents spatial color distribution and structural information is proposed. The proposed color descriptor represents color distribution of Min-Max color pairs calculating color distance between center pixel and neighborhood pixels in a block with 3x3 size. Also, the structural information which indicates directional difference between minimum color and maximum color is simultaneously considered. Then new color descriptor(min-max color correlation descriptor, MMCCD) containing mean and variance values of each directional difference is generated. While the proposed color descriptor includes by far smaller feature vector over color correlogram, the proposed color descriptor improves 2.5 % ${\sim}$ 13.21% precision rate, compared with color correlogram. In addition, we propose a another descriptor which combines the proposed color descriptor and texture characteristics based on local fourier transform. The combined method reduces size of feature vector as well as shows improved results over existing methods.

Terrain modelling is composed of a method using the rectangular grid and another using the triangulated irregular network. The method using the triangulated irregular network is most widely used because it can express the characteristics of the terrain well with only a small amount of information on the terrain and also reduces the rendering time. The process of extracting the surface-specific point and a triangular process is needed to construct such triangulated irregular network. This paper concentrates on the process of extracting the surface-specific point. The 8-direction neighborhood method and other transformed methods of the former method are frequently used to extract the surface-specific point. Another method which eliminates the unnecessary points using the Polygon reduction method is also suggested However, the 8-direction neighborhood method has a big fault of also drawing out some unnecessary points. To resolve such problem, we suggest a method of extracting the surface-specific point using the cross section of the terrain. This method reduces the time to extract the surface-specific point and enables a more precise extraction with less terrain information.

The original March algorithms cannot detect CMOS ADOFs(Address Decoder Open Faults) which requires separate deterministic test patterns. Modified March algorithm using DOF(Degree of Freedom) was suggested to detect these faults in addition to conventional stuck faults. This paper augments the modified march test to further capture NPSFs(Neighborhood Pattern Sensitive Faults). Complete CA(Cellular Automata) is used for address generation and Rl-LFSRs(Randomly Inversed LFSRs) for data generation. A new modified March algorithm can detect SAF, CF, TF, CMOS ADOFs, and part of NPSFs. Time complexity of this algorithm is still O(n).

The Purpose of this research was to propose positioning strategies of urban park (UP) based on the assessment of location characteristics at cheongju city. To do that, this research found out urban park service area (UPSA) using GIS network analysis and built socio-economic attribute database, UP map, and other public service thematic maps such as public transportation, education, child-care, and convenience services. And this research analyzed spatial and attribute data using Pearson's correlation analysis, multiple linear regression, and binary logistic regression methods. As a result of this analysis, 1) the nearer neighborhood park and children's park, the higher land price and assumption income level (AIL). 2) children's parks were closed to living convenience facilities such as bank, hospital, and convenience store. 3) land price, AIL, population, and other public services level (PSL) in UPSA were higher than that of non-UPSA. 4) The higher land price, AIL, population, and other PSL, the higher urban park service level. The results of this research may contribute to resolve the regional UP unbalance and to improve UP service level as public service.

래스터 지도에서 직선 또는 곡선과 중첩되어 있는 경우의 문자는 추출하기가 쉽지 않다. 따라서 본 논문에서는 고립되어 있는 문자뿐만 아니라 문자이외의 요소와 중첩되어 있는 문자도 효과적으로 추출할수 있는 분할 정복(divide and conquer) 개념에 기반한 문자 추출방법을 제시한다. 이를 위해 먼저 이미지의 연결 요소로부터 볼록다각형(convex hull)을 생성한다. 그리고 이 다각형이 충분한게 문자영역만을 포함할때가지 볼록 다각형을 이등분하면서 가장 긴 선분(투사 선분)을 기준으로 두 영역으로 분할한다. 다음으로 문자를 추출하기 위해서 이 선분을 기준으로 연결 요소상의 픽셀의 밀집도를 계산하는 알고리즘(프로파일링)을 적용한다. 또한 지도상에서 추출된 개별적인 문자들을 의미있는 단어들로 묶기(grouping)한 새로운 알고리즘을 소개한다. 특히 지도상에 나타나는 문자의 종류는 매우 다양하고 또한 이 문자들이 놓여있는 방향 역시 일정하지 않기 때문에 이러한 단어를 찾는 kd법은 쉽지 않다. 이를 위해 본 논문에서는 3차원 인접 그래프(3-D neighborhood graph)G를 소개한다. 이 그래프 G에서 각 노드는 하나의 분리된 문자를 나타내며 자신의 크기와 위치에 따라서 3차원 공간상에서 위치하게된다. 따라서, 크기가 큰 (작은)문자들은 보다 큰 (작은) z값을 가지고 되며 이 그래프 G에서 서로 인접한 노드들을 연결함으로써 지도상에 존재하는 서로 다른 종류의 문자 스트링을 추출할수 있다. 실험결과는 서로 다른 지도 이미지에 대해서 약 95% 이상의 단어 추출율을 보여준다.

The design principles of new urbanism (NU) have been adopted for new towns-in town projects for inner city neighborhoods in Seoul, Korea Since 2000. Here, ten NU principles were matched to four urban design categories: streets, land use, housing and buildings, and public open spaces. These elements were analyzed for Eunpyung New Town project. Through the case, the applications and implications NU principles are explored. The principles of connectivity, quality architecture and urban design, increased density, green transportation, sustainability, and quality of life were positively and successively adopted for streets, land use, housing and buildings, and public open spaces. The principles of mixed-use and diversity and traditional neighborhood structure were only partially applied in land use, housing and buildings, and public open spaces. It should be note that the walkability principle is intended not for job-housing proximity, but for pedestrian-friendly street design.

This study investigated the influences of probabilistic accessibility of the word being produced - as determined by its usage frequency and neighborhood density - on native and high-proficiency L2 speakers' realization of six English monophthong vowels. The native group hyperarticulated the vowels over an expanded acoustic space when the vowel occurred in words with low frequency and high density, supporting the claim that vowel forms are modified in accordance with the probabilistic accessibility of words. However, temporal expansion occurred in words with greater accessibility (i.e., with high frequency and low density) as an effect of low phonotactic probability in low-density words, particularly in attended speech. This suggests that temporal modification in the opposite direction may be part of the phonetic characteristics that are enhanced in communicatively driven focus realization. Conversely, none of these spectral and temporal patterns were found in the L2 group, thereby indicating that even the high-proficiency L2 speakers may not have developed experience-based sensitivity to the modulation of sub-categorical phonetic details indexed with word-level probabilistic information. The results are discussed with respect to how phonological representations are shaped in a word-specific manner for the sake of communicatively driven lexical intelligibility, and what factors may contribute to the lack of native-like sensitivity in L2 speech.
