현재 멀티미디어 기술의 발달로 인하여 영상의 전처리 및 후처리 과정을 이용한 수정 작업으로 고품질의 영상 표현 및 다양한 영상 처리가 가능하다. 영상 처리 기법 중에서 이방성 확산의 경우 영상의 스페클 노이즈 제거, 에지 검출, 영상 분할 등에 응용할 수 있는 효과적인 확산 필터링으로 활용되고 있다. 하지만 전통적인 이방성 확산은 십자형 커널을 기반으로 하고 있기 때문에 확산 필터링을 반복 적용하면 영상의 에지가 수평 및 수직 방향으로 집중되는 문제점이 있다. 본 논문에서는 기존의 십자형 커널 기반의 이방성 확산 문제점을 해결하기 위하여 기울기의 방향성에 기반한 새로운 이방성 확산 방식을 제안한다. 제안된 방식은 십자형 커널을 확장하여 대각선 방향 정보를 포함한 8방향의 정방형 커널을 기반으로 작은 기울기를 갖는 방향으로 이방성 확산을 적용한다. 제안된 방식의 실험 결과 에지가 수평 및 수직 방향으로 집중되는 문제점을 해결하면서 임펄스성 노이즈를 제거하여 고품질의 영상을 획득할 수 있었다.

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.

본 연구는 지식정보사회에서 신경제공간 형성의 메커니즘을 살펴보고 향후 지리학연구의 방향을 제시하고자 하였다. 정보화 사회에서 신경제공간의 형성 배경에 대해 개관하고, 그 메커니즘으로 네트워크, 착근성, 집적 및 분산에 대해서 설명하였다. 또한 한국에서 혁신활동이 활발한 서울의 강남지역과 낙후지역 중의 하나인 전북 순창지역에 대한 사례연구를 통하여 한국의 낙후지역에서도 신경제공간의 형성이 이루어지고 있음을 지적하였다. 이러한 이론적 논의와 사례연구를 바탕으로 앞으로 지리학연구의 방향을 크게 통합적 관점에서의 연구, 지리학연구 방법론 개발, 정책관련연구의 세 가지 측면에서 논의하였다.

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.

Localization trends in Korea and trade liberalization in the world are the important challenges to agricultural extension services in Korea, and strategic directions in terms of system, organization, programs and conciousness would be necessary for adapting to the new circunstances. Some of the measures to improve and activate agricultural extension services in Korea should include the following: 1) Modification of extension personnel appointment regulations to secure specialized extension agents by the provincial administrators and county directors at the provincial and county level rural extension services. 2) Flexible organization and operation of county level rural guidance offices to meet the specific needs of local areas. 3) Strenghening the central government's financial support for effective local extension services in terms of facility and manpower. 4) Expansion of agricultural extension programs for women and urban people and quality inservice training for extension personnel.

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.

In recent years the construction sector has grown significantly in terms of investment and research on robotics and automation, yet it is still a low-tech and disjointed industry. One of the main scopes of this paper is to determine how robotic automation can provide the answers to the needs this industry has. To that end, an overall framework and development agenda of current technological innovation in the field has been outlined. Possible drawbacks and driving forces in the development of robots in the construction site have been identified. In addition, the review provides for state-of-the-art policies and regulations, as well as the short and medium-term outlook in different markets and countries. Ultimately, the forecast impact on traditional processes, construction sites, emerging technologies and related professions has been summarized in order to delineate prospective repercussions and future directions towards self-sufficiency.
