본 논문에서는 이미지에 대한 공간 특성(Spatial properties) 및 통계적 특성(Statistical properties)을 포함한 특징이미지를 구성하고, 지역 분산 크기를 이용한 공분산 행렬을 생성하여 텍스쳐 분류에 이용함으로서 조도(illumination) 및 노이즈(Noise) 그리고 회전(Rotation)에 강인한 텍스쳐 분류 방법을 제안한다. 또한 영역 합계의 빠른 연산을 위해 사용된 중간 이미지 표현인 적분 이미지(Integral Image)를 이용함으로서 텍스쳐 검출 프로세스의 수행 시간을 최소화 하는 방법을 제공한다. 제안한 방법의 성능 평가를 위해 브로다츠(Brodatz) 질감 이미지를 이용하여 잡음 추가 및 히스토그램 명세화 그리고 회전 이미지를 생성하여 실험하였으며, 96% 이상의 성능을 얻을 수 있었다. In this paper, we make up a feature image including spatial properties and statistical properties on image, and format covariance matrices using region variance magnitudes. By using it to texture classification, this paper puts a proposal for tough texture classification way to illumination, noise and rotation. Also we offer a way to minimalize performance time of texture classification using integral image expressing middle image for fast calculation of region sum. To estimate performance evaluation of proposed way, this paper use a Brodatz texture image, and so conduct a noise addition and histogram specification and create rotation image. And then we conduct an experiment and get better performance over 96%

The tidal currents and the salinity variations of the Keum River estuary were investigated on the basis of field observations on April and August, 1983. In the tidal current observations, the semidiumal tidal current prevails and its rotary direction is revealed the count-clockwise in this area. Also, the apparently constant current which is thought to be generated by the out-flow of the Keum River is found to flow from the Kansan inner harbor to Janghang harbor with the speed of about 30 cm/sec. In addition, the salinity shows the peak at the high water, and then it begins to decrease gradually, and alas the lowest value 1-2 hours after the low water.

The stereoscopic vision system is the algorithm to obtain the depth of target object of stereo vision image. This paper presents an efficient disparity matching method using blue edge filter and graph cut algorithm. We do recommend the use of the simple sobel edge operator. The application of B band sobel edge operator over image demonstrates result with somewhat noisy (distinct border). The basic technique is to construct a specialized graph for the energy function to be minimized such that the minimum cut on the graph also minimizes the energy (either globally or locally). This method has the advantage of saving a lot of data. We propose a preprocessing effective stereo matching method based on sobel algorithm which uses blue edge information and the graph cut, we could obtain effective depth map.

우리나라 都市地域의 地價政策 課題에 關한 硏究

金永燮 漢陽大學校 行政問題硏究所 1983 行政問題論集 Vol.4 No.-

This study is an attempt to analyze the relationships between the land uses and its prices in urban areas. The following are the major findings: First, the prices of land are primarily based on the economic marginal values of land utility, and the determination of land prices, therefore, depends upon the specific land uses and the bulk of area. Thus in order to establish a reasonable land price policy, a detailed and deliberate land utilization plan must be worked out. Land pursues the highest and best utilization principles. In a free system of land uses, economic motivations dictate the land owner to consider the best marginal utility for the sake of acquiring the highest land price appraisal. Therefore, the desirable level of the land use plan is to take not account of marginal utility of economic uses but of the benefits of future generation and the welfare of the people. To curb the land price fluctuations and its misuse, we should set up more detailed land use policies and regulations. Secondly, the land price should not be allowed to be above the annual rate of general prices. If the land price outpaces the annual rate of general prices, speculations on the land in urban areas could not be prevented. Furthermore, the inflation in land price would cause a financial pressure to the local government, and its inflationary efects would spill over into other sectors of the national economy. Thirdly, the profits arising from the land development, that is, the increasing marginal values of land should be returned to the community, and economic losses caused by the development itself should in turn be adequately compensated by the community. Whenever the land price fluctuation occurs because of the land utility plans, the compensation of the losses must be negotiated at the reasonal level between the community and the profiteers. So a system of controlling the profit arising from the development of land uses can be introduced at the earliest times of developmental processes in the urban areas. Fourthly, the land use policy is particulary important in keeping the “raw land”undeveloped for preserving natural environment as well as maintaining comfortable living spaces for our next generations. On the other hand, a strict restricition on the land development, paradoxically enough, is likely to bring further hikes in land price due to the reduction in land supply. It is, therefore, necessary to reconsider the rational utilization of so-called “Green Belt”or “Productive Green Land.” Finally, the master plans of the national land, the land use policy, and the land price policy are interrelated, they all should be coordinatively designed and evaluated by consistent and collective approaches. By consistent implementation of land policies and the improvement of land ownership system, we can assure the general welfare for oursleves and for our growing generations.

The purpose of this study was to analyze the demographic characteristics, travel motivation and satisfaction of visitors to Gwangju Lake Ecology Park in Gwangju Metropolitan City to understand the characteristics of visitors using eco - tourism sites located in metropolitan areas. The survey was conducted on the field through 1: 1 interviews with visitors who visited the site, and experts meeting methods were also conducted. Most of the visitors who visited the site tended to visit nearby tourist sites while enjoying the beautiful nature with their family, friends, lovers and coworkers. Among the impacts of ecotourism on urban values, the awareness of the visitors about the preservation of the natural environment through environmental preservation and the contribution to the revitalization of the local economy through the use of lodging, food and beverages and specialty stores near the ecotourism sites and ecotourism located in the metropolitan area, As a result of analyzing the effect of urban residents on self - esteem and psychological stability, they were found to be static in general.

發展型官僚制論 : 특히 韓國官僚制의 改革과 關聯하여 With special reference to the Korean Bureaucratic Reformation

金永燮 漢陽大學校 1971 論文集 Vol.4 No.-

This thesis is an attempt to present how a specific administrative system could make its growing capability to deal continuously with new, changing problems created by rapid social and political changes. It is divided into two parts. In the first part, the writer attempts to build a limited theoretical frame-work, concerning a typology of the role pattern of "Developmental Bureaucracy" which is lamed by writer's conceptual scheme. The newly proposed model is still an ideal typology which is specially applicable to Korean administrative reformation, or some other developing countries under rapid social and political changes. The model of Developmenal Bureaucracy is a part of polar type in view of comparative perspectives of current Korean bureaucratic model and developmental model. The system analysis trough the determinant variable context is analized by structural and funcational approach toward Inter-related variables, and the selected variables are as follow : 1. Resources allocation, (control oriented or goal oriented) 2. Decision making, (routinized or creative) 3. Authority, legitimacy, responsibility, (formal or task-basis) 4. Communication, (incidental or institutionalized) 5. Man-power factors, (stagnated or influx and leakage) 6. Promotion and payment, (status basis or performance basis) 7. Leadership, (authoritative or goal setting) 8. Environment, (inadaptive or adaptive) Whether a specifilc role can realize or not the devealopmental functions such as innovative and creative capability which retaliates against the challenge of changing environment depends upon above variables interaction and relationship. Developmental model is suggested that the most important variables is "Leadership" and "Environments" and their dynamic relationship is basic determinant factors for the system's role pattern (see Chart 7, 8, 9, 10,). The second part of this theis is to apply the theoretical frameworks to the experience of the Korean bureaucracy in recent years. The effects of Developmental Model is not limited in theoretical categories. Application in a specific bureaucratic system for administrative reformation creates variable aspects. When the current Korean bureaucratic model role and developmental modal role could combinated, the role realization and conversion are showed as follow : 1. Adaptation-overall innovation of the system is possible 2. Potential adaptation-innovational energy is latent, practical innovation of system is possible, strategy of reformation has to be made gradually and cautiously- 3. Inadaptation-stagnated, bureaucratized, only wait for external supporting energy which impacts the system 4. Maladaptation-dysfunctional, bureaucratic corruption is possible, attempt of innovation is rather hazardous, only wait for external forces- The administrative reformation in view of experiences during past 20 years in korea has been circled around above four categories. The Typology (Developmental Bureaucracy) Oriention in the Development Administration Students of bureaucracy have suggested various typologies on the role of bureaucrats. Categories differ depending on the viewpoints that are applied. Some emphasize the functional aspect, while others single out the behavioral aspect of the bureaucratic role. Still other inject some normative values in to the role. To draw some illustrations, the three patterns of bureaucratic action suggested by Morstein Marx (policy formulation, policy counsel, and pubic management) is an example of the functional approach ; Eisenstadt's three categores of bureaucratic orientation (serivice, passive tool, and self-aggrandizement) represents a behavioral viewpoints. More recently, Esman's provocative two Roles (innovator and controled agent) reflects a Pronounced normative bent. The size major bureaucratic roles suggested by Weidner (innovation, leadership, change agents, administrative process or routine, specialized or technical expertise, and political or administrative liaison) present a mixture of various approaches. Professor Han-been Lee presented a philosophical and practical conception, so called "Time Orientation" (escapist, exploitationist, and developmentalist). "Time Orientation" is deeply concerned with the elite role, and human action orientation. It is composite concept corporating both the time perspective and attitude toward to changes. The proposal of Developmental Bureaucracy is to attempt a study of various role combination of system. Therefore, this paproach is mixture of various approach : for instance, discreational or regulative resources allocation (structural approach) , free floating resources function or system maintenance function (functional approach) authoritative and routinized leadership or goal setting and integrating leadership (behavioral view point), inadaptive or adaptive toward environmental change (system's analsis).
