Objective The Penn Alcohol Craving Scale (PACS) is a five-item, single-dimension questionnaire that is used to measure a patient’s alcohol craving. We sought to develop the Chinese version of the PACS (PACS-C) and assess its reliability and validity.Methods A total of 160 Taiwanese patients with alcohol use disorder were enrolled in this study. The internal consistency and concurrent validity of the PASC-C with the visual analogue scale (VAS) for craving, the Yale–Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd), and the Severity of Alcohol Dependence Questionnaire (SADQ) were assessed. The test–retest reliability of the PASC-C was evaluated 1 day after the baseline measurements. Confirmatory factor analysis (CFA) was performed to examine the psychometric properties of the PACS-C.Results The PACS-C exhibited good internal consistency (Cronbach’s α=0.95) and test–retest reliability (r=0.97). This scale showed high correlations with the VAS (r=0.81) and YBOCS-hd (r=0.81 and 0.79 for the obsession and compulsion subscales, respectively), and moderate correlation with the SADQ-C (r=0.47). Furthermore, CFA results revealed that the PACS-C had good fit indices under various models.Conclusion The PACS-C appears to be a reliable and valid tool for assessing alcohol craving in patients with alcohol use disorder in Taiwan.

Yu Su-Ping,Mao Wei-Wei 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.10

The Vehicle Routing Problem (VRP) is an important problem occurring in many distribution systems, which is also defined as a family of different versions such as the Capacitated Vehicle Routing Problem (CVRP) and the Vehicle Routing Problem with Time Windows (VRPTW). The Ant Colony Optimization (ACO) is a metaheuristic for combinatorial optimization problems. Given the ACO inadequacy, the vehicle routing optimization model is improved and the transfer of the algorithm in corresponding rules and the trajectory updated regulations is reset in this paper, which is called the Improved Ant Colony Optimization (I-ACO). Compared to the calculated results with genetic algorithm (GA) and particle swarm optimization (PSO), the correctness of the model and algorithm is verified. Experimental results show that the I-ACO can quickly and effectively obtain the optimal solution of VRFTW.

Post-earthquake fire is a common disaster which causes serious safety issues to infrastructures. This study aims to investigate the residual loading capacities of circular concrete-filled steel tube (CFST) columns under post-earthquake fire experimentally and numerically. The experimental programme contains two loading steps - pre-damage cyclic loading at room temperature and transient state tests with constant compression loads. Three finite element models are developed and validated against the test results. Upon validation, a total of 48 numerical results were generated in the parametric study to investigate the effects of thickness and strengths of steel tube, axial compression ratio and damage degree on the fire resistance of circular CFST columns. Based on the analysis on experimental and numerical results, the loading mechanism of circular CFST columns is discussed. A design method is proposed for the prediction of fire resistance time under different seismic pre-damage and compression loads. The predictions by the new method is compared with the newly generated experimental and numerical results and is found to be accurate and consistent with the mean value close to the unity and a coefficient of variation around 1%.

Yu Wang,Xiaomin Yang,Wei Wu,Bingshan Su,Gwanggil Jeon 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.10

Security checks at airport are of importance to any safe flight. Traditional method for security check is to check the luggage manually. However, this method needs lots of human labor and time. It is desired to automatically check x-ray image of the luggage with computer vision. In this paper, the illegal object classification system is implemented. First, we introduce a computer vision based x-ray inspection system for Illegal object classification. Then we propose a method by combining Taruma feature based on Contourlet transform and histogram. Finally, we apply the random forests classifier to classify these features from the illegal objects. Experimental results show that the proposed method can effectively distinguish different kinds of illegal objects.

Su-Hua Fan,Ran Yu,Feng-Qing Zhang,Quan-De Che,Wei Hu 한양대학교 세라믹연구소 2011 Journal of Ceramic Processing Research Vol.12 No.3

Ca0.4Sr0.6Bi4Ti4O15 ceramics with a-axis preferred orientation were prepared by a solid-state reaction method. The cylindrical Ca0.4Sr0.6Bi4Ti4O15 ceramics were cut into two types of plates: one was along the cylinder axis (A), and the other was perpendicular to the direction of the cylinder axis. The effects of sintering temperature on the structure and electrical properties of the Ca0.4Sr0.6Bi4Ti4O15 ceramics were investigated. When the sintering temperature was 1180 oC, sample A gave the highest a-axis (200) orientation with a value of about 27.1%. At this sintering temperature, sample A showed better dielectric properties and ferroelectric properties, the relative dielectric constant (εr), dielectric loss (tan δ), remnant polarization (Pr), and coercive field (Ec) were 217.6, 0.0027, 14.2 μC/cm2 and 49.6 kV/cm, respectively.

( Yu-ting Su ),( Xiao-rong Zhu ),( Wei-zhi Nie ) 한국인터넷정보학회 2015 KSII Transactions on Internet and Information Syst Vol.9 No.6

Since the variations of illumination, the irregular changes of human shapes, and the partial occlusions, multiple person tracking is a challenging work in computer vision. In this paper, we propose a graph clustering method based on spatio-temporal information of moving objects for multiple person tracking. First, the part-based model is utilized to localize individual foreground regions in each frame. Then, we heuristically leverage the spatio-temporal constraints to generate a set of reliable tracklets. Finally, the graph shift method is applied to handle tracklet association problem and consequently generate the completed trajectory for individual object. The extensive comparison experiments demonstrate the superiority of the proposed method.

Wei Zhou,Yu-Gang Su,Shi-Yun Xie,Long Chen,Xin Dai,Yu-Ming Zhao 전력전자학회 2017 JOURNAL OF POWER ELECTRONICS Vol.17 No.1

A novel interference isolation method is proposed by using several designed coils in capacitive power transfer systems as isolation impedances. For each designed coil, its stray parameters such as the inter-turn capacitance, coil resistance and capacitance between the coil and the core, etc. are taken into account. An equivalent circuit model of the designed coil is established. According to this equivalent circuit, the impedance characteristic of the coil is calculated. In addition, the maximum impedance point and the corresponding excitation frequency of the coil are obtained. Based on this analysis, six designed coils are adopted to isolate the interference from power delivery. The proposed method is verified through experiments with a power carrier frequency of 1MHz and a data carrier frequency of 8.7MHz. The power and data are transferred parrallelly with a data carrier attenuation lower than -5dB and a power attenuation on the sensing resistor higher than -45dB.

A Shared Channel Design for the Power and Signal Transfers of Electric-field Coupled Power Transfer Systems

Yu-Gang Su,Wei Zhou,Aiguo Patrick Hu,Chun-Sen Tang,Rong Hua 전력전자학회 2016 JOURNAL OF POWER ELECTRONICS Vol.16 No.2

Electric-field coupled power transfer (ECPT) systems have been proposed as an alternative wireless power transfer (WPT) technology in recent years. With the use of capacitive plates as a coupling structure, ECPT systems have many advantages such as design flexibility, reduced volume of the coupling structure and metal penetration ability. In addition, wireless communications are effective solutions to improve the safety and controllability of ECPT systems. This paper proposes a power and signal shared channel for electric-field coupled power transfer systems. The shared channel includes two similar electrical circuits with a band pass filter and a signal detection resistor in each. This is designed based on the traditional current-fed push-pull topology. An analysis of the mutual interference between the power and signal transmission, the channel power and signal attenuations, and the dynamic characteristic of the signal channel are conducted to determine the values for the electrical components of the proposed shared channel. Experimental results show that the designed channel can transfer over 100W of output power and data with a data rate from 300bps to 120 kbps.

Objective: The objective of this experiment was to investigate the effects of different colors produced by light emitting diode (LED) on Brown Tsaiya ducks. Methods: A total of 144 female Brown Tsaiya ducks were randomly allocated into three individual cage rearing chambers with different LED illumination colors as treatments. Three different treatments were: i) white color, ii) blue color, and iii) red color. The experiment periods were from ducks 21 to 49 weeks of age, determined traits included i) egg laying performance, ii) feed intake, iii) egg shell breaking strength, iv) egg shell thickness, v) egg Haugh unit, vi) egg weight, vii) serum Estradiol and Progesterone concentration, and viii) behavior pattern. Results: The results indicated that when compared with white and blue color, red color could stimulate ducks sexual maturation and raised the egg laying performance. The red light group was also observed to have the highest feed intake among three treatments. The blue treatment had the lowest egg shell breaking strength and the highest egg weight among three treatments, nevertheless, no significant difference was observed among three treatments on egg shell thickness and egg Haugh unit. The red light group had higher serum estradiol concentration than the white and blue groups, but no significant difference among treatments on the serum Progesterone concentration was found. The results of behavior pattern indicated that red light group showed more feeding and less resting behavior compared to the blue light group. Conclusion: We found a potential of applying red light illumination in the indoor laying duck raising system with positive results on egg laying performance and acceptable egg weight, equivalent egg qualities compared to white and blue light.

A Novel Transparent Microwave Thin Film Coating Technique Applied to Dual‑Band Antennas

Yu-Ming Lin,Hung-Wei Wu,Yung-Wei Chen,Cheng-Yuan Hung,Shoou-Jinn Chang,Yan-Kuin Su 대한금속·재료학회 2019 ELECTRONIC MATERIALS LETTERS Vol.15 No.6

In this paper, we propose a novel transparent microwave thin film coating technique and discuss its application in planardual-band antennas (0.9/5.55 GHz). We developed a new process for activating the nano-alignment thin film from high tolow resistivity (from 1.96 to 1.29 × 10−4 Ω cm) and from partial to full transparency (from 55 to 83% transmittance) within150 s. The platform of the activation process comprises a periodic electrode, an optical microscope, and an alternating currentsignal generator. The periodic electrode can effectively rearrange the nano-alignment thin film into an ordered arrangement,which enhances the properties of the thin film in the microwave frequency range. A high-transparency and low-resistivitydual-band antenna is designed and fabricated using the proposed microwave thin film coating technique. The dual-bandantenna has operating bandwidths of 740–960 and 5030–7030 MHz and potential applications in transparent electronicssuch as wearable devices and intelligent cars.
