Owing to the development in information and communications technologies have improved the technology for high-speed transmission of massive data, which has changed closed-circuit television (CCTV) video transmission technology. In particular, digitization of the CCTV video format and streaming technology has made it possible to minimize transmission loss and integrate video transmission and camera control(pan/tilt). It has also become possible to provide additional services like remote emergency warning broadcasting with just Internet Protocol (IP). However, because of the structural problems of IP, these changes have also brought about the threat of hacking of CCTV monitoring systems. In this study, we propose a methode to optimize network management by examining cases of enhancement of operational efficiency and security by improving the structure of CCTV monitoring network.

Dienes 염색법을 국내에 발생하는 마이코플라스마성 식물병의 진단에 적용해 보면서 본 염색법의 보다 효과적인 이용을 위한 실험에서 얻어진 결과를 요약하면 다음과 같다. 1 Dienes 염색법을을 통한 식물 마이코플라스마병의 진단방법은 일일초와 뽕나무에서만 지정적이었고, 대추나무, 오동나무 및 붉나무에서는 부정적이었다. 2. Dienes 염색액의 와 수용액이 일일초와 뽕나무에 각각 적합했으며, 염색시간은 분 그리고 탈색시간은 분이 좋았다. 3. 정확한 현미경적 관찰이나 선명한 사진을 위해서 절편의 두께는 가 적당하였다. 4. 공시식물의 각 부위중에서 줄기 정부 바로 밑의 부위가 좋은 결과를 나타냈으며, 엽병이나 중륵도 거의 동등한 결과를 나타냈다. 5. 이병식물에서 염색반응의 정도는 병세와 비례했으며, 병징발견 초기의 시료는 건전시료와 염색반응에 있어서 쉽게 구별되지 않았다. 6. 시료를 종절할 경우 대부분의 관요소들이 상처를 받지 않을 뿐만 아니라 정확한 관찰이 용역하므로 시료를 횡절할 경우보다 효과적이었다. 7. 염색된 시료를 현미경 관찰할 경우 filter를 사용하지 않고 텅스텐 적색광을 그대로 사용하면 사관요소와 도관요소 간의 색갈 대비를 증가시키며 정확한 해석에 도움을 주었다. 8. 시료를 고정액에 고정시키면 염색반응이 방해되었으며, 시료는 신선한 것일수록 염색반응이 뚜렷하였다.

The goals of this research project are to identify the genes controlling plant architecture through the establishment of foundation for molecular breeding and to develop new rice varieties with useful characters associated with high yield leading to its commercialization. The research subjects of this project are as follows: improvement of plant architecture including tiller angle and number associated to harvest-index, construction of genetic and QTL map related to plant architecture and isolation of target genes, development of molecular markers with high efficiency, and further study for the mechanisms of recombination event and reproductive barrier occurring from cross between subspecies, development of new elite rice varieties with high yield and its commercialization. The isolated genes and products of this research project will be patented and molecular markers for those genes will be applied to breeding procedure. The breeding materials produced as outcomes will be provided to other breeders for further breeding programs. The developed varieties will be patented and registered to the national list of varieties, and will be distributed to our agricultural industries for the increase of its competitiveness and farmer’s income. The patents for genes, molecular markers, and varieties will be licensed out to uphold the agricultural biotechnology industries.
