Taiwan Neurosurgical Spine Society: The New Shining Star

Yi-Hsuan Kuo,Jau-Ching Wu,Wen-Cheng Huang,Ming-Chao Huang,E-Jian Lee,Henrich Cheng 대한척추신경외과학회 2018 Neurospine Vol.15 No.4

As spine surgery flourished in Taiwan and neurosurgeons became more involved in spine surgery towards the end of the 20th century, the Taiwan Neurosurgical Spine Society (TNSS), earlier named the Taiwan Neurospinal Society, was established on March 11, 2001. As its main founder, Dr. Chun-I Huang was elected as the first president of the TNSS. The goals of the TNSS were to promote research, to hold academic seminars, to participate in international conferences, and to exchange clinical experiences. The mission of the TNSS was successful, and the profession of spine surgery in Taiwan advanced during the first decade of the 21st century, culminating in the TNSS joining ASIA SPINE in 2010. Since its establishment, the TNSS has always been supportive of collaboration and communication with the Korean Spinal Neurosurgery Society and the Neurospinal Society of Japan. Through periodical meetings, supported by the TNSS, surgeons worldwide have enjoyed a platform of sharing and mutual learning. To further promote academic research, the TNSS has officially supported the journal Neurospine since 2018. With extensive efforts from local and international surgeons, the TNSS will continue to adhere to its mission and to advance the profession of spine surgery.

A Versatile Fruit and Vegetable Image Recognition Method based on Deep Convolutional Neural Networks

( Yi-hsuan Huang ),( Ta-te Lin ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1

Due to the increasing labor costs and shortage of labor in the agricultural industry, automation in agriculture has become ever more important. This paper proposes a versatile and automatic fruit and vegetable recognition method through the use of computer vision and deep neural networks. The proposed method allows for detection, recognition, and localization of selected fruits and vegetables via images or video streams. Therefore, the method can be used in various applications in agriculture such as robotic harvest, greenhouse management, or crop phenotyping. To detect fruits or vegetables in images, traditional image processing algorithms have some limitations due to occlusions and background variations. Different fruits or vegetables may require different algorithms. However, deep convolutional neural networks have brought about a breakthrough in dealing with this problem. The significance of deep neural networks in imaging processing is that features are no longer extracted by image processing algorithms. Instead, the network will learn by itself from the input data and extract the important features, called deep features. Therefore, we apply deep convolutional neural networks with You Only Look Once (YOLO), a real-time object detection algorithm, to build a versatile image recognition model for selected fruits and vegetables. Using YOLO, the models are trained with five kinds of fruits and vegetables: apple, tomato, cucumber, orange and strawberry. There are two kinds of models developed: ‘one vs. all’ and ‘one vs. one’ models. These models are compared to obtain the ensemble model. In addition, the effects of different phenotype between training data sets and testing data sets are also evaluated. Finally, the optimized model is applied in the recognition system and multiple kinds of fruits are recognized. We also tested the method with images and video streams acquired from greenhouses to evaluate the performance of the method.

Forming a Fresnel Zone Lens: Effects of Photoresist on Digital-micromirror-device Maskless Lithography with Grayscale Exposure

Yi-Hsiang Huang,Jeng-Ywan Jeng 한국광학회 2012 Current Optics and Photonics Vol.16 No.2

This study discusses photoresist forming using a composite grayscale to fabricate a Fresnel lens. Grayscale lithography is a common production method used to facilitate the forming of lenses with different curvatures and depths. However, this approach is time consuming and expensive. This study proposes a method for overcoming these obstacles by integrating a digital micromirror device and microscope to supplant the traditional physical grayscale mask. This approach provides a simple and practical maskless optical lithography system. According to the results, the two adjacent grayscales displayed substantial differences between the high grayscale and influence the low grayscale that ultimately affected photoresist formation. Furthermore, we show that change of up to 150% in the slope can be achieved by changing the grayscale gradient in the central zone and the ring profile. The results of the optical experiment show a focus change with different gray gradients.

A cohesive model for concrete mesostructure considering friction effect between cracks

Yi-qun Huang,Shao-wei Hu 사단법인 한국계산역학회 2019 Computers and Concrete, An International Journal Vol.24 No.1

Compressive ability is one of the most important mechanical properties of concrete material .The compressive failure process of concrete is pretty complex with internal tension, shear damage and friction between cracks. To simulate the complex fracture process of concrete at meso level, methodology for meso-structural analysis of concrete specimens is developed; the zero thickness cohesive elements are pre-inserted to simulate the crack initiation and propagation; the constitutive applied in cohesive element is established to describe the mechanism of crack separation, closure and friction behavior between the fracture surfaces. Aseries of simulations were carried out based on the model proposed in this paper. The results reproduced the main fracture and mechanical feature of concrete under compression condition. The effect of key material parameters, structure size, and aggregate content on the concrete fracture pattern and loading carrying capacities was investigated. It is found that the inner friction coefficient has a significant influence on the compression character of concrete, the compression strength raises linearly with the increase of the inner friction coefficient, and the fracture pattern is sensitive to the mesostructure of concrete.

Anti-colonic Inflammation by Black Raspberries through Regulating Toll-like Receptor-4 Signaling in Interlukin-10 Knockout Mice

Ulcerative colitis (UC) is a chronic inflammatory disease of the colon, with a steadily rising prevalence in Western and newly industrialized countries. UC patients have a cancer incidence as high as 10% after 20 years of the disease. Although the importance of fruits and vegetables in defense against UC is beginning to be appreciated, the mechanisms remain largely unclear. In the current study, we reported that dietary black raspberries (BRBs) decreased colonic inflammation in the mucosa and submucosa of interleukin (IL)-10 knockout (KO) mice. We then used colon, spleen, and plasma from those mice to investigate whether BRBs exert their anti-inflammatory effects by correcting dysregulated toll-like receptor (TLR)-4 signaling to downregulate prostaglandin E2 (PGE2). Other studies reported that spleen is the reservoir of macrophages and depletion of macrophages in IL-10 KO mice prevents the development of colitis. Our results showed that BRBs decreased the percentages of macrophages in spleens of IL-10 KO mice. Moreover, mechanistically, the BRB diet corrected dysregulated TLR-4 signaling in cells from the colon and spleen, decreased PGE2 and prostaglandin I2, and increased 15-lipoxygenase and its product, 13-S-hydroxyoctadecadienoic acid, in plasma of IL- 10 KO mice. Therefore, we have elucidated one of the anti-inflammatory mechanisms of BRBs, and have identified biomarkers that could be indicators of response in UC patients treated with them. Our findings with BRBs could well apply to many other commonly consumed fruits and vegetables.
