Thanks to the multimedia technology development, it is possible to show image representations in high quality and to process images in various ways. Anisotropic diffusion as an effective diffusion filtering among many image preprocessing methods and postprocessing methods is used in reduction of speckle noises of ultrasound images, image restoration, edge detection, and image segmentation. However, the conventional anisotropic diffusion based on a cross-kernel causes the following problems. The problem is the concentration of edges in the vertical or horizontal directions. In this paper, a new anisotropic diffusion transform based on directions of gradient is proposed. The proposed method uses the eight directional square-kernel which is an expanded form of the cross-kernel. The proposed method is to select directions of small gradient based on square-kernel. Therefore, the range of proposed diffusion is selected adaptively according to the number of the directions of gradient. Experimental results show that the proposed method can decrease the concentration of edges in the vertical or horizontal directions, remove impulse noise. The image in high quality can be obtained as a result of the proposed method.

This study aimed to suggest practical and useful design directions for furniture for the rapidly-increasing university dormitory population. The process of the study took four steps; theoretical research, in-depth interview based on questionnaire, analysis, and development of design directions. Interviews were conducted with 25 university students living in dormitories in Seoul to find out problems with the existing furniture, students' satisfaction with the furniture, and their needs for other options. From these interviews, we found a few problems with dorm units, such as insufficient storage space, spaces too small for privacy, monotonous & standardized furniture design, and lack of multi-purpose furniture, etc. To support college students' complex lifestyles, five design directions were suggested from the analysis, such as a furniture design with highly multiple uses, modular furniture design, sufficient storage space, an application of various colors & materials, and practical use of dead space. Among these, two items were selected to be manufactured by the furniture design company. We expect that our suggested design directions for dorm furniture will support students' complex lifestyles, and satisfy students' needs with highly enhanced and better designed environments.

The purposes of this paper are to examine the mechanism of the new economic spaces and to suggest directions of geographical research in the knowledge-based information society. It introduces the background of the formation of the new economic spaces and examines network, embeddedness, and agglomeration and dispersion as mechanisms of the new economic spaces. Based on the result of case studies of Kangnam area, the most active innovation region in Korea, and of Sunchang, one of the backward regions in Korea, the paper points out that new economic spaces are now developing even in the peripheral areas. Considering the result of theoretical discussions and case studies, the paper suggests three directions for future geographical research such as research from a integrative viewpoint, development of new methodologies of geographical research, and policy directed research in geography.

The purpose of this study was to analyze the needs of future users for services at senior congregate housing and to look into the development directions of the service standards for senior congregate housing. A survey was conducted among middle-aged people in their fifties, who lived in Seoul, using the systematic random sampling method. The final sample included 498 respondents. The survey was conducted from November 3, 2003 to November 14, 2003. The results of this study were as follows. Firstly, as the need for housing services were high, it was quite clear that various services at senior congregate housing should be provided. Secondly, a service differentiation strategy should be proposed to meet the characteristics of the users. Thirdly, it was hereby suggested that service standards should be established in the following manner considering the relationship between the needs for services and the income level directly influencing the provision of services: 'Basic services' to be provided regardless of income, 'Optional services' to be selectable among the preferable services per income level, and 'Supportive services' to be provided for low-income people.

Lysophosphatidic acid (LPA) is a signaling lipid that binds to six known lysophosphatidic acid receptors (LPARs), named $LPA_1-LPA_6$. These receptors initiate signaling cascades relevant to development, maintenance, and healing processes throughout the body. The diversity and specificity of LPA signaling, especially in relation to cancer and autoimmune disorders, makes LPA receptor modulation an attractive target for drug development. Several LPAR-specific analogues and small molecules have been synthesized and are efficacious in attenuating pathology in disease models. To date, at least three compounds have passed phase I and phase II clinical trials for idiopathic pulmonary fibrosis and systemic sclerosis. This review focuses on the promising therapeutic directions emerging in LPA signaling toward ameliorating several diseases, including cancer, fibrosis, arthritis, hydrocephalus, and traumatic injury.

As the social change has been occured by industrialization and urbanization, making valuable family culture has come to be a social task. The development of family culture education program is required to create future - oriented family culture. This study aims at searching for the direction of family culture education program in Korea development to sere creating desirable family culture. For this study the concepts of family culture and family culture education were defined and the characteristics and problems of Korean family culture were discussed. Based on these discussion, the direction of family culture educational program was proposed. The directions of Korean family culture education program were suggested promotion communitarian consciousness, balancing between traditional and modern value, creating democratization among generations and genders, eqyipping with constructive communication channel, and encouraging autonomy and creativity. To work out these directions, appropriate and educational model should be mobilized to incilude whole family.

This paper presents an approach of predicting the radiated noise due to the structural vibration by internal harmonic forces using the doubly asymptotic approximation (DAA). Acoustic transfer vector is derived from the Helmholtz integral equation and the fluid-structure interaction relation of DAA. Numerical results and analytical results of radiated noise for a cylindrical shell were compared and showed that they were consistent in most of frequencies and radiation directions, but showed errors in some radiated directions in the mid-frequency region. Despite these errors, the prediction method will be suitable for practical radiated noise prediction.

This paper reviews the development of Uruguay Round of GATT talks and forecasts its effect on regional agriculture particularly concerning Chungnarn provincial agriculture. Since agriculture is composed of main industry for Chungnam economy, as imports of cheap agricultural products increase, domestic price of farm products will rapidly decrease so that it might discourage domestic production and have severe adverse consequences in regional farm economy. To cope with agricultural trade liberalization, directions which regional agriculture should pursue are suggested as follows; 1) to establish the integrated rural development strategy so as to improve living conditions in rural area equivalent to urban area, 2) to adjust the agricultural institute system facing diversification of farming type, 3) to encourage commercialized farmers in order to maintain adequate farm income, 4) to increase R&D investment on comparatively advanced technology compared with other regions, 5) to foster farmers' organization and to rear young farmers to protect family farms.
