This study investigates the development of meat analogues using vegetable proteins. Over the years, the consumption of meat analogues has increased because of environmental and religious concerns. Vegetable protein sources, especially soy, wheat, and peanuts, are commonly used as meat analogues. However, the texture of vegetable proteins does not resemble that of traditional meat. Thus, a number of studies have been conducted to improve the texture of vegetable protein-based meat analogues. The interest and demand for meat analogues, especially for recently released vegetable protein-based meat analogues, is expected to increase in the near future.

With the rapid development of wireless communication at VHF and UHF bands, there is an increasing need for the reliable propagation prediction tools. Therefore, the different propagation models that have been developed in many countries as well as korea has been trying to secure a model suitable for their geographical area but then it is giving us a different result when we compared it to measured values. In this paper, based on the measurements of DTV broadcasting services in domestic urban area, analysis and comparison of ITU-R P.1546 and BCAST models provide errors between measured and predicted values, and some points for improving SMI system has been proposed. As a result, P.1546 model provides the valid predicted data similar to measured data, but BCAST model has some problems of large deviation and higher prediction to measured data. In future, these problems and diffractions due to high buildings need to be studied further.

Recently, domestically and internationally, the occurrences of Waste Glass are on the increase. Most of scrap glass are either reused of recycled. However, glass not recycled is buriedand is causing secondary environmental problem. With 5% mixture of Waste Glass, the average paste viscosity (rheology) decreased by 22.3% and 28-day compressive strength of mortar's flow and aging decreased by 1.5% and 6% respectively. Also, as Waste Glass mixture ratio of un-hardened elf-compacting concrete increased, fluidity increased and compressive strength decreased. In consideration of adequate compressive strength and fluidity that meets the 2nd class JSCE regulations; optimum mixture ratio of Waste Glass can be concluded as 20%.

Many libraries utilize RFID tags for checking in and out of books. However, the recognition rate of this automatic process may depend on the orientation of antennas and RFID tags. Therefore we need supplemental systems to improve the recognition rate. The proposed algorithm sets up the ROI of the book existing area from the input image and then performs Canny edge detection algorithm to extract edges of books. Finally Hough line transform algorithm allows to detect the number of books from the extracted edges. To evaluate the performance of the proposed method, we applied our method to 350 book images under various circumstances. We then analyzed the performance of proposed method from results using recognition and mismatch ratio. The experimental result gave us 97.1% accuracy in book counting.

In this paper, Face recognition algorithm is designed based on optimized pRBFNNs pattern classifier using three-dimensional scanner. Generally two-dimensional image-based face recognition system enables us to extract the facial features using gray-level of images. The environmental variation parameters such as natural sunlight, artificial light and face pose lead to the deterioration of the performance of the system. In this paper, the proposed face recognition algorithm is designed by using three-dimensional scanner to overcome the drawback of two-dimensional face recognition system. First face shape is scanned using three-dimensional scanner and then the pose of scanned face is converted to front image through pose compensation process. Secondly, data with face depth is extracted using point signature method. Finally, the recognition performance is confirmed by using the optimized pRBFNNs for solving high-dimensional pattern recognition problems.

하천관리청은 유량변동이 큰 환경에서도 평상시 하천의 기능을 유지하고 안정적인 용수공급이 이루어지도록 하천수 허가관리를 수행하고 있다. 이때, 하천수 사용허가 검토시 기준으로 사용되는 유량은 자연상태의 기준갈수량에서 하천유지유량을 감안하여 적용하고 있는데, 이는 하천유량의 변동에도 최대 용수수요를 만족할 수 있게끔 관리하기 위한 것으로 최대 사용량일 때의 물의 과부족을 계산하여 허가 여부를 결정한다. 본 연구에서는 Park et al.(2016)이 제안한 시기별(홍수기/이수기, 비관개기/관개기 고려) 하천수 사용허가 기준유량 설정방법을 기반으로, 수질오염총량제(Total Maximum Daily Loads, TMDLs)에서 적용하는 안전율(Margin of Safety, MOS)의 개념을 접목하여 허가기준유량의 불확실성을 정량적으로 고려할 수 있는 방법을 제시하였다. 허가기준 유량은 수문모델에 의해 자연상태의 모의유량을 유황분석하여 도출하게 되므로 유량의 연도별 변도성(Margin of Variability, MOV)과 예측모델 매개변수의 불확실성(Margin of Uncertainty, MOU)을 고려하는 Walker Jr.(2003)의 안전율 산정방법을 적용하였다. 본 연구에서는 금호강 유역을 대상으로 시기별 자연유량 산정시 고려한 SWAT 모형결과를 기반으로 하였으며, 모의자료의 변이계수를 산정하여 시간적 변동성에 의한 불확실성을 도출하고 SWAT-CUP모형을 활용하여 모형의 불확실성을 도출하여 안전율을 계산하였다. 단, 기준갈수량이 허가기준유량으로 사용되는 기간(1월 1일~3월 31일)에는 안전율까지 고려할 경우 지나치게 보수적이라고 판단되어 적용에서 제외하였다. 본 연구에서 제안된 불확실성을 고려한 하천수 관리방법론은 시기별 하천수 허가기준유량 설정에 대한 의사결정자들의 판단을 지원하는데 기여함으로써 정책적 활용도를 높일 뿐만아니라 탄력적인 하천유량관리를 위한 기초연구로 활용될 수 있을 것이며, 타 분야 기술과의 융합이라는 점에서도 의의를 가질 수 있을 것으로 생각된다.
