The purpose of this paper is to investigate the effect of mutual coupling in the MIC array antenna. Radiation Patterns have been compared each other experimentally and analytically with and without the effect of mutual coupling. The length and width of microstrip line was determined by Wheeler's and Hammerstad's equation using computer simulation, and each patch of the array antenna was feeded with the equal power and phase. As a result of experiment, radiation pattern of the MIC array antenna with the effect of multual coupling has been improved by eliminating the gating lobes, compared with the case of no effect of mutual coupling. Finally the mutual coupling is turned out to be a most important factor for improving the radiation pattern of the antenna.

대농갱이는 동자개과의 담수어로 고부가가치를 창출 할 수 있는 새로운 담수 양식 대상종으로 주목받고 있으나 현재까지 성장도 등 양식에 대한 기초정보가 밝혀지지 않았으며, 본 연구에서는 인공으로 생산한 자 ? 치어를 사육하면서 암 ? 수의 성장 차이를 비교 ? 조사하였다. 암수의 정확한 성장 차이를 구명하기 위해 본 실험은 자어 초기 조직검사에 의한 조사와 치어기부터 표지법에 의한 조사로 구분하여 실시하였다. 조직학적 판별에 의한 암수간 성장비교 시험 결과 부화 후 50일까지는 수컷과 암컷의 성장차이는 없는 것으로 나타났으나, 부화 80일 후에는 수컷(체장 72.0±6.7㎜, 체중 3.71±6.7g이 암컷(체장 64.3±6.7㎜, 체중 3.71±0.99g)보다 성장이 빠른 것으로 나타나 대농갱이는 부화 후 50일에서 80일 사이에 암 ? 수의 성장차이가 시작되는 것으로 사료되었다. 부화 80일 이후 조사는 표지법이 개체 성장에 미치는 영향을 조사한 후 본 실험에 착수하였으며 표지구는 대조구와 사이에 유으적인 성장의 차이를 보이지 않았다. 개체간 성장차이는 조직학적 판별 결과와 동일한 경향으로 수컷이 암컷보다 성장이 유의적으로 빨랐으며(P<0.05), 시험 종료 후 암컷과 수컷의 크기는 수컷이 평균 체장 17.57㎝, 체중 52.19g으로 암컷의 평균 체장 11.02㎝, 체중 16.26g보다 체장은 약 1.5배, 체중은 약 3배이상 큰 것으로 나타났다(p=0.05). 체중으로 본 성장곡선은 지수성장을 보였으며, 수컷은 Y=0.0024X^(1.738)(R^(2)=0.985), 암컷은 Y=0.0405X^(1.0316)(R^(2)=0.983)의 지수식에 밀접하게 수렵되었고 성장의 차이는 사육기간이 길어질수록 크게 나타났다. The Ussurien bullhead, Leiocassis ussuriensis, of the family Bagridae has recently been targeted for freshwater culture in Korea. In this paper we investigated sexual dimorphism in body size in rearing condition using specimens produced artificially. Tissue sections of gonads were made between 20 and 80 days after hatching to identify sex of the specimens investigated. A difference in body size between sexes was not observed in fry until they were 50 days old. Male fry 80 days old had attained 81.62f7.21 ㎜ total length, and females 72.84±8.62 ㎜ total length. After 80 days the difference in body size was analysed by tagging. Applying the tag by cutting fin tips had no affect on the growth of the fishes (P< 0.05). The growth in body size of males was significantly faster (P< 0.05) than in females, and males attained about 1.5 times more in standard length and about 3 times more in body weight than females at the end of 320 days. The growth curve of body weight was exponential and the body weight was expressed by Y = 0.0024X^(1.738) (R² = 0.985) and Y = 0.0405X^(1.0316)(R² = 0.983) in male and female, respectively, observed at monthly intervals.

주언경,蔡鍾吉 慶北大學校 1992 論文集 Vol.52 No.-

Scrambling has been used as a method to encrypt the transmission signal for purpose of service protection from illegal use of unauthorized subscribers in Conditional Access system. More recently it is proposed to be used in a HDTV system such as MIT-CC in order to turn ghost, correlated noise, to uncorrelated white noise. In this paper, band rotation scrambling method using a modified line rotation is proposed for the band-compressed system using QMF. And scrambling effects on conversion of ghost to white noise and service protection are studied and analyzed. As results, effects of whitening ghost and service protection by the proposed method are shown to be superior to the existing line rotation method.

This study was conducted to investigate the application possibility of leaf and stem extract(LSE) extracted from the mixture of leaf and stem of ginseng radix(Panax ginseng C.A. Meyer). This study measured the intake levels and efficiency ratio, growth rate, absorption ratio of carbohydrate, lipid and protein of rat by feeding with LSE during 6 weeks. We analyse the hematological and serum metabolic variables, serum lipid concentrations. Total diet and protein intake levels were low, but efficiency ratios were significantly high in LSE administered groups than the control group. Weight gain, liver and kidney weight of LSE groups were significantly higher than the control group. Blood RBC, Hct, Hb, total protein and albumin concentrations were reasonable levels in LSE administered groups compared to the basal diet group. Also serum total cholesterol, LDL-cholesterol, triglyceride contents of LSE groups were low, but HDL-cholesterol level was higher than the basal diet group. These results imply that leaf and stem of ginseng radix could be used as possible food resources, functional food material and feed stuff.

The purpose of this paper was to separate the copper and nickel ions from waste water using supported liquid membrane The effect of a given amount of carrier and ammonia concentration of up-stream was described. We used the LIX65N as carriers. The results were as follows 1. The distribution ratio of copper ions at equilibrium was shown linear increment according o the mole ratio of carrier concentration versus the concentration of metal ions increased to 2.0. The maximum distribution ratio of copper ions exceeded that of nickel by approximately 4-fold when the liquid membrane was saturated by carrier 2. The important parameters governing flux were carrier and ammonia concentration. We compared these two parameters, and then the latter influenced more than the former to get higher flux. The copper ions reacted with ammonia in the up-stream, it formed a complexes of Cu(NH₃)₄^(2+), and then diffused to interface of liquid membrane. 3. The flux of metal ions were increased with enlarging the distribution ratio of ordinary extraction. The principle of coupled transport was carried out by the difference of concentration of hydrogen ions. 4. We can be selectively separated in the mixing soultion of copper and nickel ions using LIX65N as carrier.
