This study was conducted to develop the effects of site environmental factors on estimation of site index function for Chamaecyparis obtusa Endlicher stands. We derived nonlinear growth equation and the draw site index curves by applying this estimated equation. This study with Chapman-Richards function showed significant P-value which was less then 0.0001 and R2 value 0.5947. This study was conducted to develop the feasible site index equation of Chamaecyparis obtusa Endlicher. For the table, the data of 82 sample areas that were thought to be without errors among the data of Chamaecyparis obtusa Endlicher sample area located on the value-oriented forest location chart were used and estimated. After analyzing the quantification method I based on 13 environmental factors to develop the score table for the site-index estimation of Chamaecyparis obtusa Endlicher, R2 value of the model was 0.7555. It has been analyzed that the scope value of Soil moisture in horizon A was 7.5045, that of total soil depth was 6.3896, that of topography was 5.3471, that of slope was 4.7000 and that of aspect was 3.2038. After analyzing the partial correlation to examine the factors that affected most the site-index of Chamaecyparis obtusa Endlicher, it has been noted that the partial correlation of climatic zone was 0.4987, which was highest, and it was followed by Soil moisture in horizon A (0.4592), slope (0.4537), topography (0.3299) and total soil depth (0.1035). As a result of conducting the significance test for partial correlation, it has been found that topography, climatic zone, parent rock, slope, altitude, aspect, Soil moisture in horizon A, soil hardness in horizon A and total soil depth were recognized significant with 1% of significance level and sedimentary type and soil texture in horizon A were recognized significant with 5% of significance level.

A completely new flying machine is developed and the details for practical iplementation is suggested. The proposed machine contains no moving parts so that it can be operated in noiseless manner. This paper presents some operational principles of the flying machine as well as the overall process of designing the basic ionic flyer model. The validation of the model is checked by experiments of test flights. Also, two conceptual design results for practical implementation are introdiced with the derivation of design parameters. The application field is expected to include indoor secrete surveillance as well as ion propulsion.

Recently, brick pavement were widely introduced on the pavement in rural area. A variety of vision effects can be created from patterns of brick pavement. However, in most of brick pavement works, human psychological characteristics were not concerned. The purpose of this research was to discover psychological effect on brick pavement pattern. The results of the research can be summarized as follows: 1)Psychological impression on brick pavement pattern is similar among man and woman groups. 2)Stack bond and running bond pattern have a simple, relaxed, organized, and comfortable psychological characteristics. Basket weave & stack bond pattern has a simple and organized psychological characteristic. Herringbone bond pattern has a complex, dislike and uncomfortable psychological characteristic. Pinwheel bond pattern has a highly complex psychological characteristic. Basket weave and Basket weave variation bond pattern have a common psychological characteristic. 3)Employment of brick pavement pattern on this research is not highly preferred, hence it is necessary to develop a brick pavement patterns that have human psychological characteristics be concerned.

본 연구에서는 복숭아 '미백도', '대구보' 및 '유명' 과실의 발육단계별로 과실의 경도, 세포벽성분 및 g1ycisidase 활성의 변화를 조사함으로써 수확후의 저장중 과실에서와 같이 발육중인 과실의 연화에서 도 -galactosidase가 중요한 역할을 하는지 알고자 하였다. 조사시기는 5월 13일, 6월 16일, 7월 16일, 8월 5일이었으며, 수확기가 늦은 '유명'은 8월 28일에 한번 더 조사하였다. Total sugar와 비섬유성 중

초산균을 달리하여 제조한 감자식초의 품질을 상호 비교하여, 초산균에 따른 품질 특성을 조사하였다. 3종의 감자식초에 대한 pH는 2.90∼3.09, 총산 함량은 5.30∼5.60%로 큰 차이를 나타내지 않았으나, Acetobacter sp. PA96을 이용한 감자식초(II)의 색상은 감자식초(I, III)과 구별되었다. 또한 acetic acid를 제외한 유기산 조성은 Acetobacter sp. PA97을 이용한 감자식초(I)에서 citric

To utilize abundant potatoes effectively, it was studied on alcohol fermentation strains which were isolated and identified. Fifteen yeast strains with high alcohol fermentation ability were isolated from rotted potatoes. Among them, two isolated strains, 5-3A and 10-4B showing the highest alcohol fermentation ability were identified as Zygosaccharomyces fermentati based on the morphological and physiological characteristics. Their optimum conditions for the alcohol fermentation in 25% glucose were pH 3.0, 30 and 150 rpm of shaking speed, respectively.

대부분의 연갑류에서 androgenic gland (AG)는 수컷의 성 분화와 성징의 발달에 관여하는 호르몬을 분비하는 것으로 알려져 있다. 징거미새우, M. nipponense의 AG는 제5보각 (fifth waking legs)의 저절 (coxopodite)내에 위치한 사정관과 수정관의 말단부 (distat vas deferens)사이에 위치하고 있었다. AG는 단일 세포 가닥 (simple cellular strand)들로 이루어져 있고 이들 세포
