In this paper, we propose a program to identify 14 parking status in a parking lot using a high resolution 360° camera of 12M. The proposed program consists of three steps: Match with plane image, parking area detection algorithm, and discrimination of parking using learning method. Tests on a model car to evaluate the program to identify 14 parking status in a parking lot using a high-resolution 360° camera of 12M showed 100% accuracy for both parking and double parking. Therefore, the effectiveness of a program to identify 14 parking status in a parking lot using a high-resolution 360° camera of 12M proposed in this paper has been proved.

In Fe–3%Si steel, the hot rolling process affects not only the hot rolling texture but also the primary recrystallization texture. Here, the effect of asymmetric hot rolling was studied by comparing the difference in the texture evolved between asymmetricand symmetric hot rolling. The effect of asymmetric hot rolling on the texture of primary recrystallized Fe–3%Si steel wasalso studied. The symmetric hot rolling of Fe–3%Si steel produces a rotated cube texture at the center but Goss and coppertextures near the surface. Asymmetric hot rolling tends to produce Goss and copper textures even at the center like thetexture near the surface. After primary recrystallization, the dominant texture at the center changes from {001} <210> to{111} <112> and the new texture has a higher fraction of the grains which make the low energy boundary with Goss grainsthan that of symmetric hot rolling.

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

The objectives of food waste composting are to treat the wastes and to reclaim valuable substances present in the wastes for possible reuse. In the process of food waste composting, however, the salt in the compost can be retained within the soil for extended periods of time. In this study, therefore, a series of experiments were carried out to investigate the leaching characteristics of the salts in the compost of food waste. The resalts obtained from this study can be concluded as follows: 1. The composting process reduced the amount of waste to management because the 80% of water content in the food waste was lowered to 10% of that in the compost, and organics substances in the food waste were decomposed into CO₂, NH₃, water, and various inorganic substances. 2. It was found that the amount of toxic substances such as heavy metals in the food waste were very little, therefore, the metal concentration might not cause any adverse effect on the growth of the corps. 3. The concentrations of leachable cations in the compost were 10∼20% higher than those in the food waste of around 1000 meq/kg. And, SAR of the leachates of the food waste and compost was around 3. 4. The leaching rate of the salts in the compost was decreased with increasing the composting period. Also, the electric conductivities of initial leachate were increased with increassing the mixing ratio of the compost to the soil used. 5. The threshold dose of the compost per day per unit area of the soil was estimated with the following equation: mmho 12.0meq·cm kg 1.65L Threshold dose= 5______ × ___________ × _______ × _____ cm L·mmho 1200meq d·㎡ = 0.08kg/㎡/d

콘크리트는 본질적으로 인장강고와 휨강도가 약하며 취성적 성질을 나타내는 결점을 가지고 있으므로 이를 보강할 목적으로 콘크리트에 섬유를 혼입한 섬유보강 콘크리트가 크게 각광받고 있다. 특히 폴리프로필렌 섬유보강은 모르타르 및 콘크리트가 건조나 동해에 의해 수축될 때 구속에 의해 발생되는 인장응력 및 균열을 제어하고 인성의 증가와 충격, 마모, 피로에 대한 저항성, 내구성을 증대시키는 장점을 가지는 것으로 보고 되고 있다. 1축으로 구속된 건조수축의 구속으로 인한 조강형 콘크리트의 잔류응력을 선형모델을 이용하여 예측할 수 있었고 조강형 콘크리트에 섬유보강으로 인한 건조수축 제어효과는 일반큰코리트에 비해 효과가 매우 큰 것으로 나타났다. 따라서 폴리크로필렌 섬유의 혼입으로 인해 콘크리트의 균열제어가 가능하며, 균열 폭이 큰 균열보다는 많은 미세 균열을 유도하는 것을 알 수 있었다. 섬유보강 조강형 큰크리트의 동결융해저항특성은 거의 동해의 손상을 받지 않으며 좋은 내구성을 유지하고 있는 것으로 나타났다. 이는 불규칙하게 배향된 섬유가 공극수의 이동을 효과적으로 제어함으로써 메트릭스 내의 팽창압으로 인한 파괴를 최대한 줄였기 때문이라고 보여진다. 표면손상과 박리저항에 매우 우수하며 저항성을 증진시키는 효과가 뛰어남을 확인할 수 있었다. 따라서, 내구적 측면의 유지, 보수에 있어서도 섬유보강은 그 효과가 큰 것으로 나타났다. To improve the brittle nature of concrete, discrete fibers can be adapted in concrete. Since polypropylene fiber has many advantages in many points on its chemical stability and good durability, its usages have been increased gradually. It has been reported than polypropylene fibers can not only control restrained tensional stresses and cracks, but also increase toughness, resistance to impact, corrosion, fatigue, and durability. Although the polypropylene fiber reinforced concretes with ordinary cement have been studied so much, those with very early strength concretes have not studied at all. Therefore, it is necessary to initiate and conduct the researches for the polypropylene fiber reinforced very early strength concretes which has enough workability and durability. This study of polypropylene fiber reinforced very early strength concrete focused on the investigation each material's effect into strength development with analysis of restrained shrinkage properties with one-dimensional concrete members. The results showed that more optimized mixture combinations could be selected in very early strength concrete by incorporating polypropylene fibers, keeping in same strength levels at urgent repair works. The formation of needle-shape ettringite helps the early strength development, specially at flexural and this enables the repaired concrete structures or pavements to be opened to traffic after 3 hours of concrete placement. A residual stress of early strength concrete caused by one-dimensional restrained drying shrinkage was predicted from linear model. the control of shrinkage crack by fiber reinforcement at early strength concrete was better than that of ordinary portland cement concrete because of bridging effect of fiber at early age and resulting of more hair cracks rather than fewer wider cracks. As a results, this dissertation clearly validated the fiber reinforcement on the strength development and durability of polypropylene fiber reinforced very early strength concrete, and characteristic of restrained shrinkage. The proposed optimized concrete mixtures might be satisfactory applied at the repair works in fields, because of its durability and crack control capacity against freeze-thaw and contraction at early age, respectively.

A computer vision system for recognition and processing any visible objects is designed. Analog video images are digitized and stored in the internal memory of a microcomputer system and these digitized data are output through a bit-image printer. The kirsch edge operator is used for the processing. In order to compare the result of Kirsch edge enhancement, two images "a Man" and "a figure" are tested. Because of the limitations of the speed of A/D converter and the capacity of internal memory, the operation of the system is a still-picture mode. Upper 4 bit date of the memory are used for printing out the image, so as to the gray levels are sixteen. The output size of the bit-image printer is 120x120, and 2 horizontal lines are printed simultaneously per 1 carriage return because the printer has a 8 pin head. The system is designed to have compatibility with any microcomputer system which has a S-100 bus structure.
