Background: The prevalence of prostate cancer (PCa) has been increasing in recent years. Treatment strategies are largely based on the results of bone scan screening. Therefore, our aim was to investigate predictors of positive bone metastasis in newly diagnosed PCa patients. Materials and Methods: After extensive review, 336 consecutive patients newly diagnosed with PCa between April 2010 and November 2013 at our institution were enlisted in the study. Patients were divided into two groups according to bone scan results. Univariate analyses (Chi-square test for discrete variables and independent t-test for continuous variables) were applied to determine the potentially significant risk factors associated with distant bone metastasis. Binary logistic regression analyses were used to further investigate the influence of these factors on bone metastasis. Results: The patient mean age was $71.9{\pm}8.6years$ (range: 48 to 94 years). The mean prostate specific antigen (PSA) level and biopsy Gleason score were $260.2{\pm}1107.8ng/mL$ and $7.4{\pm}1.5$, respectively. The body mass index (BMI) for the series was $24.5{\pm}3.4kg/m^2$. Sixty-four patients (19.0%) had a positive bone scan result. Patients with positive bone scan results had a significantly lower BMI ($23.3{\pm}3.5$ vs. $24.8{\pm}3.3$; p=0.003), a higher Gleason score ($8.5{\pm}1.1$ vs. $7.1{\pm}1.5$; p < 0.001), and a higher PSA level ($1071.3{\pm}2337.1$ vs. $69.4{\pm}235.5$; p < 0.001) than those without bone metastasis. Multivariate logistic regression analysis employing the above independent predictors demonstrated that a Gleason score of ${\geq}7$, clinical stage ${\geq}T3$, $BMI{\leq}22kg/m^2$, and an initial PSA level of ${\geq}20ng/mL$ were all independent predictors of bone metastasis. Conclusions: A bone scan might be necessary in newly diagnosed PCa patients with any of the following criteria: clinical stage T3 or higher, a Gleason score of 7 or higher, BMI equal to or less than 22, and a PSA level of 20 or higher.

This study proposes an application of the classical rock mass classification concept on the estimation of in situ hydraulic conductivity of regolith and fractured bedrock which can be utilized to evaluate groundwater potential in mountainous areas. On the basis of boring logs, borehole televiewer image data, and double packer hydraulic test data conducted in the Basin of Jhuoshuei River of central Taiwan with the aid of bivariate analysis, two rock mass permeability classification systems (Hydro-Potential value for Regolith (HPR) and Hydro-Potential value for Bedrock (HPB) System) were developed. By regression analysis, the dependence of HPB/HPR on in situ hydraulic conductivity was performed, and two empirical models for estimating in situ hydraulic conductivity were derived. Meanwhile, two derived models were validated through the comparison against results from other types of hydraulic test data (pumping and single packer tests). Therefore, the development of the empirical models for a groundwater-related project enables to help the planning of detailed investigations for the determination of hydraulic conductivity with cost-effectiveness.

Human-Oriented Recognition for Intelligent Interactive Office Robot
Chia-Ming Wang,Shin-Huan Tseng,Pei-Wen Wu,Yuan-Han Xu,Chien-Ke Liao,Yu-Chi Lin,Yi-Shiu Chiang,Chung-Dial Lim,Ting-Sheng Chu,Li-Chen Fu 제어로봇시스템학회 2013 제어로봇시스템학회 국제학술대회 논문집 Vol.2013 No.10
This paper presents our new intelligent interactive robot, which is constructed to eagerly provide multi-functional services in an office environment. In order to endow a full interactive capability of our robots for realizing so-called human-robot interaction (HRI), we propose sensor fusion based human detection and tracking system and human pose estimation to deal with a number of situations which may take place in the office environment. Not only by these perceptions, human interact with the robot also by some natural way, such as touching the interface screen and talking with the robot through microphone. Finally, the effectiveness of the proposed work is tested and validated by some of experiments.

This study investigated the psychological effects of the long-term military intimidation imposed by the People’s Liberation Army (PLA) on the Taiwanese public. Online texts dating between 2016 and 2018 were mined and Russell’s (1980) semantic analysis was used to analyze the online discussions among the Taiwanese public regarding the PLA vessels and aircraft patrolling around Taiwan. The results showed that the PLA’s long-term encirclement patrols have generated numbness among the Taiwanese public. With regard to the Taiwanese government’s policy of disclosing information about such military encirclement patrols, the effects of proliferating this information were not significant, but have led to an increased sense of fear among the public. These ndings suggest that the effects of the PLA’s encirclement patrols around Taiwan are not determined by the PLA, but by the Taiwanese government’s policies regarding the disclosure of relevant information on encirclement patrols.
