Industrial crowd and specialization by the regional high technology industrial complex can maximize the synergy effect by economical effect and value chain in a dominant position, support the appropriate industrial environment that the industrial technology development by region technology renovation system construction and the product system of the flexible speciality. There are three common points to be found in the general selecting standards for upbringing high technology industrial business in Gwangju. First the growth motive power of the globe promising high technology industry are, information technology industries, confrontation of industries due to advanced age, global environmental allied industries, and the undeveloped allied industries(such as new materials, mechatronics, space aeronautics, traffic industries, etc). Second, Nation wide promising high technology industry should be; industries based on 5-year plan with industrial technology development, industries based on national vision and development of the strategies, promising industry based on technology. Third, the regionally located industries and the specialized industries such as optical industries. The successful reasons of upbringing high technology industrial are supporting with high qualified human resources, good condition on circulating capital, perfect infra system, developing the consumer market, reliable circulation system, economical network system construction based on renovation, convenient shipping system construction, various tax benefits, neighboring districts civilization, etc. Thus, regional industry accumulating complex upbring the technology renovation high technology industries can increase the industries of international competitiveness, national industrial economic promotion, the consummation of provincial promotion and territorial balanced development, and right to appropriate the government's budget based on the investment plan on concentrated industrial complex. They can strengthen the national competitiveness.

This study was investigated physicochemical characteristics of residential wastes in using volume-base charge system of disposal bag. It examined from August 31, 1999 to March 30, 2000 to Asan city. It divided residing conformation to singleness house, few stories apartment (below 5 layers), high-rise apartment (more than 6 layers). Samples were collected 20ℓ volume bag by each 3 volume-base charge system of disposal 1 times by season in total 27 areas. Total 108 samples were analyzed characteristics of living wastes and three ingredients (moisture, volatile solids, ash) by season and house types. 1. Mean bulky density in the volume-base charge system of disposal envelope showed by 0.206 tons/㎥. Bulky density in high-rise apartment was the lowest by 0.183 tons/㎥ by house types, and few stories apartment and singleness house appeared similarly by each 0.217 tons/㎥, 0.218 tons/㎥. 2. Weight by season of waste in volume-base charge system of disposal bag was the highest in winter and the lowest in spring. 3. Occurrence amount by composition ratio about total weight combustibility was 93.3%, and incombustibility was 2.8%, and recycling was 4.0%. In physical composition, the compositional weight fraction was food, 47.9%, paper, 27.8%, vinyl & plastics, 10.7%, textile 3.4%. 4. In combustible wastes, the compositional weight fraction was food, 51.3%, paper, 29.8%, vinyl & plastics, 11.4%, textile, 3.7%, In combustible wastes, the compositional weight fraction was glass & ceramics, 85.3%, and soil & others, 9.1%, and metal was 5.6%. Glass bottles of recycling were 36.8%, plastics kind 24.6%, and can kind was 3.8%. 5. Average moisture content of combustible wastes appeared 28.60±22.35% and moisture content of food kind highest by 45.29%. Ash content was few amount of 6.55%. Volatile solids amount was high by 64.84% but vinyl & plastics was the highest by 78.05%, and food was the lowest by 46.83%. 6. Three ingredient findings moisture contents by season of combustible waste were the highest in summer and the lowest in winter (p<0.01).

2차원 Quadrature Polar Separable 필터의 최적 설계

박종안,박승진 한국통신학회 1991 한국통신학회논문지 Vol.16 No.5

An improved 2-D quadrature polar separable (QPS) filter and its applications to texture processing are discussed in thie paper. The frequency response of the filter consists of two independent parts. The first is a radial weighting function based on the prolate spheridal sequence(PSS). The second is the same orientational function of the angle as in the Knutsson filter. The new filter is suboptimal in the energy loss because we let the polar angle function approximate the radial weighting function as in the 2-D Cartesian filter composed of two PSS's. It is easy to control as it depends only upon the design specification of the bandwidth, the drectional agnle, and the central freqneucy. Also the filter is circularly more symmetric in the frequency domain than the Knutsson filter. In order to estimate the orientation and the frequency component of loca textures in the frequency domain, some applications of the new filter, such as the generation of synthetic textures, the estimation of texture orientations, and texture segementations, are discussed.

도시기본계획상 주요 계획지표 설정의 적절성에 관한 연구: 계획인구, 시가화예정용지, 도시공간구조 설정을 중심으로

박종안,이강엽,채병선 국토연구원 2011 국토연구 Vol.68 No.-

A comprehensive city plan planned in the past years of rapid urbanization, based on increase in population, had established and used land use plan and urban spatial structure. However, as the population growth has entered a phase of stagnation and mobility among regions has also stabilized, such plan in the past needs its change. In this study, characteristics of projected population, planned urbanized area and urban spatial structure in the 82 comprehensive city plans are investigated in terms of, regions, population size, population growth trend, city types and groups. The results show that the projected population of 82 cities is excessively set up, which led to an excessive set-up of planned urbanized area and a consequent low density of population. Besides, a reckless establishment of central place caused a distortion in urban spatial structure. This will be likely to bring about insufficient use of land, increase in costs for infrastructure and city management. This study suggests a planning fitted for the characteristics of each city, plans centered on metropolitan area. 과거 급속한 도시화시기에 마련된 도시기본계획은 인구증가를 전제로 하여 토지이용계획, 도시공간구조 등을 수립하는 방식으로 운용되어 왔다. 하지만 인구성장이 정체되고 지역 간 인구이동 역시 안정화되어가면서, 인구증가를 전제로 한 계획 수립방식에 대한 재고의 필요성이 증대되고 있다. 본 연구에서는 82개 도시기본계획상 계획인구 설정치와 시가화예정용지, 도시공간구조 설정과의 관계를 지역별, 인구규모별, 인구성장추이별, 도시형태별, 군집별로 분석하여 특성을 고찰하였다. 그 결과 82개 도시의 계획인구가 과다 설정되고 있었으며, 이는 시가화예정용지의 과다설정과 이로 인한 밀도 저하로 이어지고 있었다. 또한 무분별한 중심지 설정으로 도시공간구조 왜곡현상이 나타나고 있었다. 이로 인해 효율적인 토지이용의 저해, 기반시설 및 도시관리 비용의 증대 등의 문제점 발생이 예상되고 있으며, 본 연구에서는 각 도시별 특성에 맞는 계획수립지침의 마련 및 운용, 광역자치단체를 기본으로 하는 계획의 수립 등을 대안으로 제시하였다.
