  • 본 연구에서는 제주도의 사면별 강수 분포 특성을 파악하고자 하였다. 기압배치와 상층 풍향별로 4개 기상관측소의 일별 강수량 자료를 분석하였다. 제주도의 강수량은 북서사면 보다 남동사면 쪽이 많다. 그리고 대부분 온대성 저기압과 장마전선, 태풍에 의한 것이며, 앞의 두 경우는 남.동사면, 태풍에 의한 것은 북사면에 많다. 태풍에 의한 호우는 사면간의 강수량 차이가 적고, 저기압에 의한 것은 동서사면간, 장마전선에 의한 것은 남북사면간의 차이가 크다. 풍향별로는 남동과 남서풍계에 의한 강수가 많은데, 겨울에는 북서풍계에 의한 강수도 많다. 기압배치형 보다는 기류의 방향에 따라서 사면간의 강수량 차이가 크며, 남서, 남동풍계가 우세한 여름에는 남사면 강수량이 많고, 북서와 북동풍계가 우세한 겨울에는 북사면이 많다. 사면간의 강수차이는 미우인 경우 더욱 뚜렷하고, 미우는 겨울 북사면에 많다.

  • 본 연구에서는 우리나라 6개 지점(강릉, 서울, 인천, 대구, 부산, 목포)에서 관측한 약 100년간(1912-2009년, 단 1950-1953년 제외)의 일최고/최저기온 및 일강수 자료를 이용하여 각 지점별로 다양한 기후지수를 산출하고 이들의 변화를 살펴보았다. 기온 관련 기후지수로는 여름일수, 영하일수, 결빙일수, 서리일수, 열대야일수, 냉방도일, 난방도일, 일교차, 식물성장일수, 일최고/최저기온의 월최고값 및 월최저값 등을 분석하였으며, 강수 관련 기후지수로 강수량, 강수일수, 강수강도, 호우일수, 미우일수, 최고 일강수 및 5일 연속 최고 강수량, 연속건조일수 및 연속습윤일수, 극한 강수일의 강수량 등을 계산하였다. 다음은 6개 지점의 기후지수를 평균한 결과이다. 6개 지점 모두에서 최저기온의 상승률이 최고기온의 상승률보다 크게 나타남에 따라 분석기간 동안 일교차는 점차 줄어드는 경향($-0.12^{\circ}C$/10년)을 보였고, 최저기온에 근거한 기후지수인 서리일수 (최저기온이 $-5^{\circ}C$ 미만, -2.6일/10년), 영하일수(최고기온이 $0^{\circ}C$ 미만, -1.0일/10년) 등의 감소와 평균기온의 상승에 따른 성장계절길이(growing season length)의 증가(+3.53일/10년)가 뚜렷하게 나타났다. 일강수와 관련된 주요변화로 미우일수(일강수량이 1 $mmday^{-1}$ 이하)는 감소(-0.75일/10년)했지만, 10 $mmday^{-1}$ (+0.32일/10년), 20 $mmday^{-1}$ (+0.27일/10년), 30 $mmday^{-1}$ (+0.25일/10년), 50 $mmday^{-1}$ (+0.17일/10년), 80 $mmday^{-1}$(+0.09일/10년) 이상 내린 강수일수는 증가하였다. 강수강도(강수량이 1 $mmday^{-1}$ 이상일 때의 강수량과 강수일수 기준)는 0.23 $mmday^{-1}$/10년로 증가했다.

  • In this study, we evaluated the salinity tolerance of five forage rice cultivars (Mogwoo, Mogyang, Miwoo, Jowoo, and Yeongwoo) with respect to germination, seedling growth, productivity, and feed values in a reclaimed paddy field in Muan, Korea. We found that the cultivars Mogwoo, Miwoo, Jowoo, and Yeongwoo showed normal germination and seedling growth, even at saline concentrations of between 0.1% and 0.5%, whereas in contrast, there were significant reductions in the germination and seedling growth of Mokyang with an increase in salt concentration. Among the five cultivars assessed, the seedling growth of Mogwoo and Yeongwoo was relatively higher at different salt concentrations in hydroponic and sand cultivation. Furthermore, cultivation of the five cultivars in the reclaimed paddy field with an initial salt concentration of 0.3% revealed that Yeongwoo was relatively superior in terms of yield and feed value. In conclusion, the germination and early growth of Yeongwoo were relatively good at high salt concentrations, and the yield and forage value of this cultivar in a reclaimed paddy field were also relatively superior to those of the other assessed varieties.

  • This thesis aims to present how to make secure the identity of the brand with enhancing the esthetic expression of the brand and making the ways of emotional communication in variety, through investigating closely the case of Prada representative of the typical brands that have established the unique identity by cooperating the fashion with culture and art through their ingenious and consistent efforts. In the conclusion, the culture and art was found to be applied in two fields i.e. one of design and the other of marketing. In terms of the design, the method of inserting the image into the surface of the clothing and accessories was used. In the context, the illustration techniques, photographic patterns and applying the image of the art piece could be summarized to be used. In terms of marketing, the sponsorship of the art and exhibitions, look books, animations and fashion films, epicenter, the collaboration with the other kinds of enterprise, could be regarded as four ways of the approaches. The innovation and creativity, futuristic hybrid, nonprofit support of the art, the integration and consistency of the image of the arts could be concluded to be four major points defining the characteristics of the Prada renowned for the use of the culture and arts to its property.

  • Add-drop filtering effect of a asymmetric fiber-optic coupler ADF(add/drop filter) is analyzed using a new split-step time-domain model. This model is very useful in simulating the devices containing a directional coupler an Bragg gratings, First, a symmetric fiber-optic coupler ADM is analyzed using this model to confirm the accuracy of the new method. Then, an asymmetric fiber-optic coupler ADF is analyzed, and some design parameters for optimal filtering effect is derived.

  • Effect of Film thickness on the sensing behavior of thin-film-type ags sensor has been analyzed by deriving an equation form a simple model, and the equation was applied to the sensing behavior of ${SnO}_{2}$ and CuO-${SnO}_{2}$ thin-film sensors. It was revealed, from the equation,that the gas sensing property was closely related to gas diffusivity into the film which was a function of film thickness, reactivity of the gas detected with sensing material, operating temperature, etc. The equation derived was well consistent with the experimental results from ${SnO}_{2}$ and CuO-${SnO}_{2}$ thin-film sensors and explained their different ${H}_{2}S$ sensing behaviors. Finally, a medel was suggested, explainning the effect of gas diffusivity on sensing be havior of oxide semiconductor sensor.
