The purpose of this study is to investigate the effect of dot pattern size(0.8, 1.8, 2.5, 5, 8), color combination (BG/R, Y/B), value tone(lt/dk, p/g), area-ratio on image information. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 20 color pictures manipulated with the combination of dot pattern size, color combination, value tone and area-ratio using computer simulation. The subjects were 240 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, visibility, chastity.feminity, cuteness and attractiveness. In the visibility, color combination, value tone, area-ratio, dot pattern size showed independent effect. In the chastity feminity, color combination, value tone, showed independent effect. In the cuteness, value tone, area-ratio, dot pattern size showed independent effect. Significant interaction effects of color and area-ratio combination on visibility and cuteness were found. Interaction efforts of color and value tone combination, value tone and area-ratio was significant on cuteness. For visibility image, BG/R combination of color and yellow background/blue dots were effective. For cuteness image, pale/grayish tone and background/dots area-ratio were effective.

The two agricultural zones, mid-and-northen region and southern region, were established according to the possibility of double cropping in the paddy field. For each agricultural zone typically mechanized farming systems with a power tiller for cultivating rice, barley and soybean were established. A computer program, which determines the optimum size of power tiller for the given farm size, the ratio of paddy area to total area and the ratio of double cropping area to the paddy area, was developed. The computer program was executed for the farm sizes, 1 to 3 ha, and the ratios of paddy area to the total area, 60~80%, and the ratio of double cropping area to the total paddy area, 70%. The following conclusions were drawn from analyzing the computer outputs. 1. In the mid-and-northern region, a smaller power tiller (5 or 6 PS) appeared to be more economical for the farm size up to 3 ha. From the viewpoint of fuel consumption a 6 PS power tiller appeared to be more favorable. 2. In the southern region, a smaller tiller (5 or 6 PS) appeared to be more economical for the farm size up to 1.5 ha. But, a larger power tiller (8 or 10 PS) appeared to become more economical as the farm size and the barley planted area increased. 3. For the southern region where rotary tilling is heavily required due to double cropping, it is recommended to develop a power tiller which weighs light like the conventional 5 or 6 PS small power tiller but has lager power.

Purpose: As the medical environment changes, the size of medical facilities continues to change. Of course, it is not easy to analyze the correlation between changes in the medical environment and changes in facility size in a rigorous scientific method. However, the results of investigating and analyzing changes in the size that occurred for any cause be able to serve as important references for future medical facility architectural plans. Methods: This study surveyed 68 general hospitals in Seoul for 15 years from 2005 to 2020. The change in the number of beds was investigated with data from the Ministry and Welfare. The gross area change was confirmed by analyzing the of all hospitals. Results & Implications: As a result of the survey, general hospitals in Seoul show a common phenomenon in which all hospitals except one case have expanded their size in the direction of increasing the gross area per bed over the past 15 years. However, in the method, a relatively small hospital with less than 500 beds mainly chose to reduce the number of beds. Large hospitals increased both the number of beds and the gross area, however showed a significant increase in the gross area.

Purpose: Regional public hospitals have implemented functional reinforcement projects, and the facilities to accommodate them have increased in size. Nevertheless users in hospital are concerned about space shortage and area imbalances. Therefore I will trace the factors and trends that influence the size, and derive the relationship between these and the uses' critical opinion. Methods: Among the indicators for determining the size of medical facilities, the number of beds and total floor area are the essential indicators that directly affect the composition of space and allocation of area inside the medical facility. The purpose of this study is to investigate the change and the factors of change on the these two indicators in regional public hospitals and analyze the trend of changes. Results: In accordance with support undertaking, regional public hospitals have been increased the number of chronic-based beds and expanded additional facilities such as O.P.D specialized centers, emergency centers and funeral homes for reflecting the needs of the regions and times. However, as a result of analyzing the area, regional public hospitals are growing in size mainly on the ward and O.P.D is only expanded the scope of functional reinforcement division but total area level of O.P.D is lower than the recent level. In addition, the levels of D&T, Supply, mechanical/electrical equipment area related to medical support and control environment quality are very low. This is because the functional reinforcement projects have been done without concerning diagnose the whole facility. Implications: If functional reinforcement projects are conducted, to cope with problems of space shortage and imbalance of area, it is judged that an architectural planning that comprehensively analyzes existing facilities and related departments should be included.

The purpose of this study is to find out the characteristics of area and spatial elements according to the building size and provide the guidelines for space planning of the child care center. This study used the content analysis method and analysis was made on the floor plans for 51 cases and the floor plans were converted to Autocad drawings to analyze the area. The results of this study were as follows; 1) Child care centers over 70% were single-attached building types which made it possible for creating outdoor environments for children. However, most small-size centers which had under 50 children did not have the facilities for outdoor activities. 2) In terms of spatial elements, the basic spaces of the small-size center were the classroom, bathroom, kitchen, office and reference room. The medium or large size centers had extra rooms for special activities and service spaces in addition to the basic spaces. 3) Classroom area per child was 2.65 m2 on average. Space composition ratio on average for care, staff, and service was programmed by 57%, 9%, 34% respectively. Small-size center had relatively more care space when compared to the others. In the case of large-size centers, there was a tendency that service space was increased, but care space was decreased.

The conventional BMA is performed with the fixed block size. For better performance at low bitrate, the block size is required to be large in relatively stationary area, while small in moving area. Thus, in this paper, a video coding technique using variable block size model is proposed. It decides the block size based on the degree of local motion defined by the local mean and variance of blocks. Computer simulation shows that the proposed method gives comparable performance to the conventional one with less bits required for motion vector coding.

본 연구는 서울 도시 비오톱(n=54)을 대상으로 서 식지 면적 에 따른 조류 종수를 파악하고자 2001년 가을과 2002년 봄에 실시하였다. 도시 비오톱을 대상으로 조사한 조류종수의 연구에서 비오톱 면적의 크기가 조류종수에 뚜렷한 영향을 미치지 않는다고 생각되어진다. 전체 대상지에서 32종의 조류가 관찰되었으며 1㏊미만에서 는 13종, 1-10㏊에서 는 29종, 10㏊이상의 면적에서는 8종의 조류가 나타났다. 비오톱 면적 크기에 따른 조류종수의 증가에 관한 연구에서, 면적의 크기가1-10㏊인 대상지가 <1㏊ 이거나, > 10㏊인 대상지보다 더욱 많은 조류가 관찰되었다. 또한, 종-면적 축적 곡선에서 는 작은 면적의 서식지가 추가되어졌을때 종수의 증가율이 지속적으로 높아졌다. 이에 도시 지역에서 조류 종수의 증가를 위해 필요한 최소면적은 1-10㏊가 효과적일 것이라 생각된다. 또한, 수자원과 다양한 식생구조를 가진 비오톱에서 조류종의 뚜렷한 증가를 보였다. 따라서 이러한 환경의 조성은 작은 면적의 서식지도 조류종의 증가에 도움이 될 수 있을 것이다.

Air-water interfacial area is of great importance for the analysis of contaminant mass transfer processes occurring in the soil systems. Capillary bundle model has been proposed to estimate the specific air-water interfacial areas in unsaturated soils. In this study, the measured air-water interfacial areas of a soil (loam) using the gaseous interfacial tracer technique were compared to those from capillary bundle model. The measured values converged to the specific solid surface area (7.6×104 ㎠/㎤) of the soil. However, the simulated air-water interfacial areas based on the capillary bundle model deviated significantly from those measured. The simulated values were substantially over-estimated at low end of the water content range, whereas the model under-estimated the air-water interfacial area for the most of the water content range. This under-estimation is considered to be caused by the nature of the capillary bundle model that replaces the soil pores with a bundle of glass capillaries and thus no surface roughness at the inner surface of the capillaries is taken into account for the estimation of the air-water interfacial area with the capillary bundle model. Subsequently, appropriate correction is necessary for the capillary bundle model to estimate the air-water interfacial area in soils. Since the soil-moisture release curve data is the basis of the capillary bundle model, the model can be of use due to its simplicity, while the gaseous tracer technique requires complicated experimental equipment followed by moment analysis of the breakthrough curves. The size distribution profile of the pores filled with gas estimated by the water retention curve was found to be similar to that of particle size at different size range. The shifted distribution of gas-filled pores toward smaller size side compared to the particle size distribution was also found.
