Three CNN (Convolutional Neural Network) models of GoogLeNet, VGGNet, and Alexnet were evaluated to select the best deep learning based image analysis mothod that can detect pavement distresses of pothole, spalling, and punchout on expressway. Education data was obtained using pavement surface images of 11,056km length taken by Gopro camera equipped with an expressway patrol car. Also, deep learning framework of Caffe developed by Berkeley Vision and Learning Center was evaluated to use the three CNN models with other frameworks of Tensorflow developed by Google, and CNTK developed by Microsoft. After determing the optimal CNN model applicable for the distress detection, the analyzed images and corresponding GPS locations, distress sizes (greater than distress length of 150mm), required repair material quantities are trasmitted to local maintenance office using LTE wireless communication system through ICT center in Korea Expressway Corporation. It was found out that the GoogLeNet, AlexNet, and VGG-16 models coupled with the Caffe framework can detect pavement distresses by accuracy of 93%, 86%, and 72%, respectively. In addition to four distress image groups of cracking, spalling, pothole, and punchout, 22 different image groups of lane marking, grooving, patching area, joint, and so on were finally classified to improve the distress detection rate.

본 연구에서는 LSW를 이용한 피틴의 생산과정에서 기존의 알칼리 중화법의 단점을 극복하고자 효모발효에 의한 자연 침전법으로 피틴을 회수하는 공정을 개발하였다. LSW에 함유되는 약 3%(w/v)의 젖산은 약 33시간의 효모 발효에 의하여 소모되고 pH가 7.5 정도로 상승함에 따라 LSW에 함유된 피틴산이 기존의 중화법에 사용되는 Ca(OH)2의 투입 없이 피틴으로 침전되어 분리되었다. LSW의 효모발효에 의하여 생성된 피틴의 농도는 약 1.0%(w/v)였으며, 단백질함량은 12.3%(w/w)로서 중화법으로 생산된 피틴보다 현저히 낮은 수준이었다. 또한 효모 발효에 의하여 생성된 피틴은 중화법으로 생성된 피틴보다 약 1.6배 빠른 침전속도를 나타내었다.

Weissella viridescens와 Leuconostoc carnosum은 육가공 제품 변패 미생물 중에서 중요한 미생물 로 인식되어 왔다. 용아초(Agrimonia pilosa)는 아시아에 널리 분포해 있으며, agrimonolide, agrimophol, agrimoniin, agrimol, agrimonic acid A, agrimonic acid B와 같은 다양한 플라보노이드를 함유하고 있다. 본 연구에서는 용아초의 추출방법에 따른 W. viridescens와 Leu. carnosum에 대한 생육저해효과를 탐색하였다. pH 11로 조정된 물 추출물과 50%(v/v) 에탄올 추출물은 W. viridescens 와 Leu. carnosum에 대하여 각각 43%와 24%에 해당하는 생육저해효과를 나타내었다. 그러나 사용된 추출용매와 상관 없이, 추가적인 초음파 추출은 용아초 추출물의 항균활성 증진에 큰 영향을 미치지 않았다.

This paper proposes the heuristic approach for the generalized GT(Group Technology) problem to consider the restrictions which are given the number of cell, maximum number of machines and minimum number of machines. This approach is classified into two st

EP was obtained through 20% ethanol extraction of Pueraria lobata root, and the fermented form of EP, FEP, was prepared from the EP after incubating with Lactobacillus rhamnosus vitaP1. There was no significant toxicity by EP and FEP up to 1000 ㎍/㎖ in NIH-3T3, HaCaT, and B16F10 cells. In addition to antioxidant potentials of EP and FEP determined by DPPH and ABST assays, we confirmed increase of procollagen type I and elastin synthesis by supplementation of the EP and FEP at the concentration of 50 ㎍/㎖ using ELISA kits. The protein expression levels of matrix metalloprotease (MMP)-1, -3, and -9, those are involved in the degradation of collagen or other skin matrix proteins, were remarkably suppressed while their inhibitory protein metallopeptidase inhibitor 1 (TIMP-1) was greatly up-regulated by supplementation of the EP and FEP at a concentration of 50 ㎍/㎖. Taken together, both EP and FEP supplementation could be involved in the suppression of the skin wrinkle formation through inhibiting degradation of collagen and stimulating the synthesis of collagen and elastin. The results showed that the anti-wrinkle potential of the EP and FEP will be a promising candidate for developing cosmeceutical compounds or products.

The result of this experiment which are conducted, to improve the cultivation technology of Alisma plantago, to increase its quantity and to contribute for stable production with Yongiun local group by examining the optimal planting density and transplanting period of double cropping of Alisma plantago in the southern region. The characters of plant height, leaf width and length tend to be reduced as the seeding period is later by the order of the 10th, 20th and 30th of July. The period required for flowering is reduced as the transplanting period is later and dense planting is applied. Plant height, the number of leaves and yield of dry root have much quantity at the dense planting density of 20× 15cm as they are transplanted later in the 30th of August or the 10th of September, but they are rather less in sparse planting density of 20×25cm or 20×35cm.
