This study was carried out to analyze the effect of changes in the light environment caused by the daylight disturbance on the productivity and quality of the standard cut flower rose cultivar 'Monet'. It was artificially shaded to obstruct the sunlight and the productivity and growing characteristics of roses according to the time of daylight disturbance were investigated. The number of cut flowers per unit area (3.3m²) of the cut flower rose 'Monet' was 40 stems in the control, while in the 4-hour, 8-hour, and 12-hour treatments, it was 32, 29, and 25, respectively. As the daylight disturbance time was increased, the number of cut flowers showed a tendency to decrease. In the case of cut flower characteristics related to the quality of cut roses, all characteristics such as flower width, flower height, petal length, and petal width, decreased by 10 to 20% in the 12-hour treatment compared to the control. In addition, growth characteristics such as peduncle length, peduncle thickness, and cut flower height, which determine the marketability of cut roses, also tended to decrease as the daylight disturbance time increased. On the other hand, the number of days to flowering increased by 14.0% from 24.3 to 27.7. The overall growth characteristics were contracted and flowering was delayed as the time of daylight disturbance increased. In the results of this study, as the daylight disturbance time increased, flower size, cut flower length, and fresh weight was decreased. This is due to the decrease in the total photosynthetic amount as the daily average photosynthetic photon flux density (PPFD) was decreased, resulting in a decrease in the quality of roses. It is judged that it is because they do not receive enough carbohydrates necessary for growth and development.

본 연구는 일조방해에 의한 광 환경의 변화가 스프레이 국화의 생육과 개화, 절화 품질에 미치는 영향에 대해 분석하기 위해 수행하였다. 이를 위해 절화용 스프레이 국화 '옐로우캡'과 '피치팡팡' 품종을 인위적으로 차광 처리하여 무차광 대비 66% 정도의 일조를 방해하였고, 이에 따른 국화의 생육 및 개화 특성, 채화량 등을 조사하였다. 일조방해에 따른 국화의 단위면적당 채화량은 차광과 무차광 처리구에서 유의미한 차이는 없었으나, 개화소요일수는 차광 처리에서 '옐로우캡' 품종은 72.1일, '피치팡팡' 품종은 65.2일로 무차광에 비해 각각 14.1일과 8.9일 정도 개화가 지연되었다. 꽃의 크기와 꽃 수 역시 차광 처리에서 '옐로우캡'과 '피치팡팡' 두 품종 모두 각각 10%와 15%, 30%와 28% 정도 감소하였으며, 화경장은 품종별로 각각 10%와 20%, 줄기의 굵기는 23%와 37%, 절화 생체중은 32%와 33% 정도 감소하여 절화 국화의 품질이 크게 저하되었다. 본 연구의 결과에서 차광 처리한 국화의 개화가 지연됨은 물론 꽃의 크기와 꽃 수가 감소하고 절화의 길이와 생체중 등이 모두 감소한 것으로 볼 때, 인공 건축물 등에 의한 일조방해는 국화의 생장과 화아분화, 화아발달에 필요한 광량을 제한함으로써 절화의 생산성과 품질을 저하시킬 것으로 판단된다. 따라서 일조방해로 인한 국화 재배농가의 피해 구제를 위해 차광 정도에 따른 수확량 감소율 및 상품성 가치 하락률 등에 대한 추가적인 연구가 필요하다. This study was carried out to analyze the effect of changes in the light environment caused by the daylight disturbance on the growth, flowering, and cut flower quality of spray chrysanthemums. The spray chrysanthemum 'Yellow Cap' and 'Pitch PangPang' cultivars for cut flowers were artificially shaded to interfere with 66% of sunlight compared to the non-shading, and then the growing and flowering characteristics, and cut flower yield were investigated accordingly. There was no significant difference in the cut flower yield per unit area between the shading and the non-shading treatments. However, the number of days to flowering was 72.1 days for the 'Yellow Cap' and 65.2 days for the 'Pitch PangPang', which were delayed by 14.1 and 8.9 days, respectively, compared to the non-shading light. In the shading treatment, the flower diameter and the number of flowers also decreased by 10% and 15%, and 30% and 28% for both 'Yellow Cap' and 'Pitch PangPang', respectively. The stem length also decreased by 10% and 20%, the stem diameter by 23% and 37%, and fresh weight by 32% and 33%, respectively. The shading treatment delayed the flowering of chrysanthemums and reduced the growth such as flower diameter, number of flowers, and the length and weight of cut flowers. Based on these results, the daylight disturbance by artificial buildings is expected to reduce the productivity and quality of cut flowers by limiting the light intensity needed for chrysanthemum growth, flower bud differentiation, and flower development. Therefore, further research is needed on the rate of decrease in yield and market value according to the degree of shading to relieve damage to chrysanthemum growers caused by the daylight disturbance.

본 논문에서는 항공기 레이더에 적용 가능한 능동배열 안테나의 배열오차 분석 및 보정에 대한 시험 결과를 기술하였다. 복사소자, TR 모듈, 급전기 등으로 구성되는 배열소자 간의 크기 및 위상오차는 안테나 부엽 준위에 영향을 미치며, 이는 안테나 개구면 weighting에 따른 이상적인 부엽레벨, 배열소자 개수, 안테나 효율 등에 의해 그 민감도가 달라진다. 시스템에서 요구되는 부엽준위를 만족시키기 위해서는 배열소자의 오차 보정이 반드시 이루어져야 한다. 그 방법은 오차요소에 따라 다르게 적용되어야 하며, 안테나 형태, 목표 부엽 준위에 따라 고려되는 수준의 차이가 달리 적용되어야 한다. 본 논문에서는 배열오차 요소와 그 영향에 대해 분석하였으며, 오차 보정 방안을 제시하였다. 또한, 근접 전계 시험을 통해 그 결과를 확인하였다. Array error analysis and correction of active array antenna are described in this paper. Array elements composed of radiator and TR(Transmit & Recive) module have error(magnitude and phase difference among array elements) which affects SLL(Side Lobe Level). Error affectedness level depends on ideal SLL according to antenna aperture weighting, number of array elements and antenna effective aperture. To satisfy required SLL, correction of array elements is necessary; adopted differently per errors, and weighted differently per shapes of antenna and required SLL. Errors of every individual element had been defined, performance of the antenna with or without error correction had been estimated and proved through near field test.
