This study is to analyze the influence of paste flow, compaction time and compaction thickness on the fundamental properties of porous concrete. Results of this study were shown as follows; 1) As paste flow increase, compaction time according to paste flow and compaction thickness decrease. Also, though paste flow is same, as compaction thickness increase, compaction time Increase. So It must be considered that the influence of compaction time according to paste flow and compaction thickness. 2) In the range of this study, compressive strength is the highest value at paste flow 190mm. 3) Occasion of manufactured compactor in this study compaction thickness 10, 15cm is influenced heavily but compaction thickness 20cm is influenced slightly.

The proportion of diesel vehicle is very high in this country . PM and NOx emitted from diesel-posered vehicle is severely ;affecting to be air quality . Especially, diesel particulate matters(DPM) including black smoke are hazardous air pollutants to human health and environment. In order to reduce the exhaust emissions from diesel engines, it is necessary to analyze the characteristics of exhaust emissions from diesel engines in various driving conditions. Recently, there are occasion to increase the fuel consumption rate to engine power up. So, in this study we have tested a diesel engine detached from in use -diesel vehicle and analyzed exhaust emission by driving condition and fuel dispersion rate. From this results, we will prepare the comprehensive management plan for exhaust emissions from diesel vehicles and contribute to the improvement of air pollution in urban area.

This study was intended to identify the desired image and fabric preference of woman college student for apparel and the relationship between these variables. Data were collected by questionnaire distributed to 260 woman college students through August to September of 2000. After eliminating incomplete questionnaires, 236 were analyzed. The most desired image was neat, and the most preferred fabric was natural fiber textile in fiber contents and light and soft in fabric sensation. The avoided image was masculine, and the negative sensation was heaviness. As a result of factor analysis, 7 factors -cute, intellectual, animate, neat, mature, sporty, sexy- were determined in image. And 8 factors -soft, durable, flat, rigid, light, bulky, heavy, pliable- were determined in fabric sensation. These factors explained large percentage of variance respectively. Multidimensional scaling was employed to analyze the relationship between desired image and fabric preference. Two dimensions were accepted to interpret the relationship. One of the results showed the closeness among the natural fiber textile, lightness, durability and natural image. And the short distance among the blended textile, elasticity, warmness and sporty image was presented.

A ten-year-old, male cat presented with recent loss of body weight, depression, vomiting, anorexia, polydipsia, and polyuria. General physical findings included depression, weakness, severe dehydration and a strong acetone odor on the breath. A complete blood count and serum biochemical profiles were leukocytosis, hyperglycemia (286 mg/dl), hypokalemia (2.6 mEq/L), hyponatremia, and high serum fructosamine (600 $\mu$mol/L). In blood gas analysis the cat had acidosis (pH 7.127, p$CO_2$26.7 mmHg). In urinalysis glycosuria and ketouria were appeared. On the basis of clinical signs, serum chemistry, blood gas analysis and urinalysis, diabetic ketoacidosis was diagnosed. Treatment included subcutaneous administration of protamine zinc insulin (0.75 U/head) and intravenous administration of 0.9% saline. Potassium phosphate and sodium bicarbonate was added to the fluids. Serum fructosamine for assessment of glycemic control was measured on occasion calls. On day 296, the patient improved clinically and did not experience any problems resulting from diabetic ketoacidosis.

컴퓨터와 통신의 발달은 멀티미디어 개발 및 보급에 기여하였으며, 특히 인쇄매체를 대체하고 '전자'화된 전자교과서 시대를 열었다. 그리하여 그 동안 많은 전자교과서 모형 설계 및 개발이 이루어져 왔으며, 그 효과 또한 입증 된 바 있다. 따라서 본 논문에서는 전자교과서의 이점을 살려 초등학교 특별활동 의식행사 활성화에 기여하고자 한다. 현행 초등학교에서 특별활동 일환으로 실시되고 있는 의식행사는 '교과교육 외의 활동'으로 취급 되어 지면서, 교과서 없이 지도서만 가지고 형식적이고 한시적인 내부계획에 따라 진행 되었다. 이에 초등학교 특별활동 의식행사 전자교과서 모형 개발을 제안한다. 이 모형은 학습자로 하여금 다양한 멀티미디어 자료 학습을 통해 흥미와 관심을 갖고 의식행사에 참여할 수 있게 설계 하였으며, 기존의 전자교과서 기능에서 전자노트 기능을 추가하였다. 또한 교수자 측면에서는 전자교과서를 쉽고 간단하게 학습에 적용시킬 수 있도록, 학습모형에 기반 하여 설계함은 물론, 학습자료 구성하기 및 훈화자료 만들기 시스템을 통해 전자교과서의 활용 폭을 넓혔다.

Germination respone to sulfuric acid treatment, temperature, light and underwater condition were experimented for Albizzia julibrissin Durazz. seed. It took 60 minutes to break the dormancy of impermeable seed for the effective sulfuric acid treatment, and temperature sensitivity was decreased by 90 minutes' treatment. The germination rate of the seed was highest, i.e. 96% at 60 minutes acid treatment in a 21。C growth chamber. On the occasion of light sensitivity, the seed was light indifferent. The imbibition rate of seed was higher at 27。C than 21。C and in proportion to the period of acid treatment time. A. julibrissin Durazz. seed were well germinated at underwagter condition.

The main object of this study was to clarify the concept, scheme, an dimensions of the clothing evaluatie criteria, and to organize its theoretical framework accordingly. The research was carried out in tow ways. The first research was investigated by the critical evaluation of the existing literature, while the other research was investigated by an empirical survey study. The questionnaire was developed for the empirical study. The questionnaire was administered to 640 housewives living in Seoul area during the fall of 1988. Social wear was selected according to the defined times, place, and occasion. As a result of the literature study, the first research problem, the clothing evaluative criteria was loud to exist at three different level - benefit level, element level, and intemediate level -. The colthing evaluative criteria at the benefit le·eel were loud to include four different dimensions-fashionbility, status symbolism, practicality, and economy. The validity of the benefit dimensions was established by the empirical confirmation utilizing factor analysis technique.
