지자체 차원의 균형발전 계획을 수립하기 위해서는 현 상태의 도시공간구조를 파악해야 한다. 특히 중심지는 균형발전의 핵심 요소이므로 그 위치와 규모를 정확히 판단하는 것이 필요하다. 따라서 본 연구는 부산시를 대상으로 중심지 체계를 식별하고 중심지의 기능을 누릴 수 있는 중심지의 영향권에서 소외되는 지역을 도출하고자 하였다. 중심지 체계 식별을 위해 부산시 전역에 대해 4개 지표(지가, 생활인구, 카드 소비, 상업 용도 건축물)를 활용하여 중심지 면적 지수를 산출하고 Getis-Ord Gi*와 DBSCAN 분석을 수행하였다. 식별된 중심지에 대해서는 위계를 구분하고 위계별 네트워크 분석을 통해 영향권을 도출하였다. 분석 결과 중심지는 서면, 중앙, 연산, 장산, 해운대, 덕천, 동래, 대연, 사상, 부산대, 부산역, 사직 총 12곳으로 나타났다. 중심지 영향권 소외지역은 대부분 동부산권역과 서부산권역에서 나타났으며 노후 공업지역과 주거지역, 신도시 일부에서도 도출되었다. 본 연구는 기존 연구에서 다루지 않았던 머신러닝 방법론을 적용하여 기존 계획상 중심지와 실제 데이터 간 차이를 밝히고 중심지 위치와 소외지역을 식별하였다는 점에서 의의가 있다.

Christaller의 중심지모형은 공간분석 연구에서 가장 설득력 있는 개념과 이론구성을 가진 것으로 평가되어 왔지만 동시에 많은 비판들을 받아왔다. 특히, 이 모형의 한계로서 중심지체계의 변화를 적절히 수용하지 못하는 정태성의 문제가 지적되었다. 본 연구는 교통발달이 중심지체계를 변화시키는 원리를 규명하기 위해 중심지모형을 선형상권분석모형으로 재구성한 바, 교통비용의 하락이 어떻게 중심지의 상권을 변화시키게 되는지를 분석하였다. 모형분석의 결과는 다음과 같다. 교통발달은 고차중심지의 상권을 확대하는 반면 저차중심지의 상권 축소와 기능 쇠퇴를 가져올 것이다. 더하여 이러한 현상은 고차중심지와 저차중심지가 규모에서 차이가 클수록 거리가 가까울수록 상품의 중심성이 높을수록 크게 나타나며, 쇠퇴의 속도는 교통발달 속도가 일정할 경우 점점 더 빨라지게 된다. 나아가 상권의 형태는 저차중심지를 향해 오목하게 나타날 것이다.

This study aims to derive the life service supply structure in rural areas of Jeollabuk-do through the analysis of the centrality of life service in Eup/Myeon central area. In addition, mutual relationship between the settlement system in rural areas and the current status of the supply of living services in Eup/Myeon areas were also analyzed. In particular, in this study, the entire administrative districts of Jeollabuk-do are intended to be established as a single wide area unit, breaking away from the current status of living service supply at the Si/Gun level. This study mainly conducted with three points. First, the spatial range of Eup/Myeon central districts with centrality in terms of living service supply was established. Second, the hierarchical structure of the living service supply system in the rural areas of Jeollabuk-do was investigated through the analysis of the living service supply level based on the centrality and geographical distribution in Eup/Myeon central districts. Based on the analysis results, the central place system of rural areas in Jeollabuk-do was established in terms of living service supply. Third, through the analysis of the living service functions distributed in the central area, and the type of living service supply by hierarchy was identified.

Recently, the space organization of Korean-Chinese houses is different from that of other territories. The vast land of China, coming from different hometown in Korean peninsula, and the different hometown in Korean peninsula, and the different procedure of settlement seem to make the different space organization of Chinese-Korean single family housing at the urban area in Liaoning Province.The characteristics of the Korean-Chinese space organization of single family housing at the urban area in Liaoning Province are as follows;i)Three types of space organization are central kitchen type, central corridors types, and central living room type. ii)The central kitchen type is mainly in old urban housing, after 1980's, the central corridor type appears in single family housing, and central living room type appears 1990's.iii) It seems that the main reason to change the space organization are fuel, system of heating, influence of Korea housing. Especially, Korean-Chinese like central living room type that is suitable for sit down living style. This central living room type supposes to be used as popular space organization in urban housing.

The objective of this study was to determine physicochemical changes in brown rice during ageing condition. Five varieties (Haiami, Ilpum, Daecheong, Jungwon, and Dasan1) of brown rice were stored at $35^{\circ}C$ for 8 weeks. Crude protein and lipid content, seed germination rate, fat acidity, tocol content, TOYO glossiness value, pasting properties, and composition of storage proteins were measured to evaluate its quality during storage. The isomers of tocols (tocopherol and tocotrienols) were quantified using HPLC system, and the pattern of variation in rice storage proteins was examined through electrophoresis of protein extracts. Seed germination rate decreased by 2.7 times, whereas the fatty acid value dramatically increased by 4.8 times after 8 weeks of storage. Toyo glossiness value of cooked milled rice considerably affected by storage period, and the pasting properties of milled rice were also influenced by storage. The final viscosity and breakdown value increased, but setback decreased during storage. In terms of storage protein, proportion of prolamin (14.3 kDa) and globulin (26.4 kDa) increased, whereas percentage of glutelin (34-39 kDa and 21-22 kD) decreased. Furthermore, the contents of total tocol and isomers decreased in stored brown rice.

Recently, the CAD/CAM system to automatically design and process are used in almost every industry world. We designed an original digitizer system to digitize a real size car drawing. We succeeded in the development of super large size Laser Digitizer System (LDS) which has input area of 2m by 6m, resolution of 0.1mm and accuracy of .+-.0.5mm. This Laser Digitizer System can use in design of cars, ships, planes and big maps. Also can use in sensing the position of nozzle head of laser processing system, and so on.

BACKGROUND: Mixed cropping of legume and grass was effective system in view point of providing organic matter and nitrogen or reducing the nitrogen starvation of following crop. The relation of the change of N and P constituents depending on the cropping types and those effects on the growth and nutrient uptake of the following crop were observed. METHODS AND RESULTS: Three cropping types, hairy vetch mono cropping, barley mono cropping, and mixed cropping of hairy vetch and barley were applied. Soil properties, growth characteristics, and nitrogen production of green manure crops were observed. In additions, the effect of cropping types on the growth pattern of corn as the following crop was observed. In the mixed cropping system, creeping type hairy vetch climbed to the erect type barely for light utilization resulting in improvement of light interception rate and higher LAI (Leaf Area Index) than in mono cropping. Mixed cropping showed higher biomass production and soil nitrogen availability among the cropping types, indicating relatively much more nutrient supply and higher yield production of following crop. CONCLUSION: Mixed cropping showed relatively higher LAI (dry matter) mainly because of intense competition for light utilization usually after flowering stage. Mixed cropping also showed relatively higher yield of corn, the following crop rather than other types, mainly due to the more biomass production potential and higher N and P production ability. Therefore, mixed cropping was adaptable method to reduce or replace chemical fertilizer application for environmentally-friendly agriculture.

Sesame has been consumed for centuries as flavoring ingredient in eastern Asian countries, especially Korea. Sesame seeds have been used as health food for traditional medicine to prevent disease in Asian countries for several thousand years. Sesame seed has higher oil content (around 50%) than most of the known oilseeds. Sesame oil is rich in monounsaturated and polyunsaturated fatty acids. Extraction of sesame has developed significantly over the years. The mechanical method was an early means of separation which was physical pressure to squeeze the oil out. Nowadays, solvent extraction becomes the commonly used commercial technique to recover oil from oilseeds. In this study, we investigated extraction efficiency and quality of oil affected by cultivars and extraction methods of sesame seed. Different variables were investigated; roasting temperature ($170{\sim}220^{\circ}C$), extraction methods (solvent and physical pressure), forced ventilation system and cultivars. The Contents of B(a)P in sesame oil after roasting at $170{\sim}220^{\circ}C$ were 0.30~2.53 ppm. When we introduced forced ventilation system during roasting, B(a)P Contents were decreased up to 36%. The Oil extraction efficiency on sesame seed was statistically depending on the cultivars and extraction methods. The oil extraction yields of solvent and physical pressure extraction were 56.3% and 44.6%, respectively. Many of sesame cultivars and genetic resources are linolenic acid content of less than 0.5%. The results supported that we have developed a safe and high quality sesame oil processing methods for small and medium-sized companies.
