( Chia Hung Tsai ),( Lu Huei Chen ),( Chao Chi Lin ),( Su Feng Cheng ) 한국선거학회 2011 선거연구 Vol.1 No.2

혼합선거제도는 영국의 전통적 소선거구제와 비례제 양자 모두의 좋은 점을 제공한다고 언급된다. 학자들은 후보자와 정당들이 이러한 선거 규칙에 어떻게 반응하는지 고찰해 왔으며, 이 제도 하에서는 상이한 유인 요인이 존재한다고 주장해 왔다. 두 개의 서로 다른 층 간의 상호작용 또한 연구의 대상이 되어 왔다. 본 논문은 소선거구제에서의 투표 행태가 정당의 명성에 의해 영향 받는 정도를 평가해 보고자 하는데, 이는 소선거구 선거 결과와 비례대표 선거 결과 간의 차이에 의해서 측정된다. 대부분의 유권자가 비례대표 표를 던질 때 자신들의 선호를 따르며, 소선거구 표를 던질 때는 현직자를 고려할 것이라고 우리는 가정한다. 한국, 대만, 그리고 일본에서의 투표 행태를 비교함으로써, 사회적 배경, 정치적 태도, 쟁점에 대한 의견 등이 투표 행태에 미치는 상대적 영향력을 이들 세 국가에 걸쳐서 평가할 수 있다. 분석에 사용되는 자료는 선거제도 비교연구(CSES) 2차조사 (2001-2006), 21세기 전국적 장기 설문조사 자료 (JES 3차), 대만의 선거 및 민주화 연구 자료 (TEDS 2008L)이며, 이를 통해 각기 한국의 2004년 총선, 대만의 2008년 의회선거, 그리고 일본의 총선을 고찰한다. It is said that mixed-member systems offer the best of both the traditional British single-member district system (SMD) and proportional representation systems (PR). Scholars have examined how candidates and parties respond to the electoral rule, arguing that there are different incentives for them. The interaction between the two tiers is also investigated. This paper attempts to assess the extent to which voting behavior in the SMD districts would be influenced by party reputation measured by the difference between the SMD and PR voting results. We assume that most voters follow their preferences when they cast their PR votes, but that they consider the incumbents when they cast their SMD ballots. Comparing voting behavior in Korea, Taiwan, and Japan, we are able to assess the relative effect of social backgrounds, political predispositions, and issue opinions on voting behavior across three countries. We use CSES Module 2 (2001-2006) data, the Nation-wide Longitudinal Survey Study on Voting Behavior in the 21st Century (JES III) data, and Taiwan`s Election and Democratization Study (TEDS 2008L) data to examine voting behavior in the 2004 National Assembly election of Korea, the 2008 legislative election of Taiwan, and the 2005 general election of Japan respectively.

Background and Purpose It is essential to develop a reliable predictive serum biomarker for Parkinson’s disease (PD). Te accumulation of alpha-synuclein (αSyn) and up-regulated expression of Rab35 participate in the etiology of PD. Te purpose of this investigation was to determine whether the combined assessment of serum αSyn and Rab35 is a useful predictive biomarker for PD. Methods Serum levels of αSyn or Rab35 were determined in serum samples from 59 sporadic PD patients, 19 progressive supranuclear palsy (PSP) patients, 20 multiple system atrophy (MSA) patients, and 60 normal controls (NC). Receiver operating characteristics (ROC) curves were calculated to determine the diagnostic accuracy of αSyn or/and Rab35 in discriminating PD patients from NC or atypical parkinsonian patients. Results The levels of αSyn and Rab35 were increased in PD patients. The serum level of Rab35 was positively correlated with that of αSyn in PD patients. Compared to analyzing αSyn or Rab35 alone, the combined analysis of αSyn and Rab35 produced a larger area under the ROC curve and performed better in discriminating PD patients from NC, MSA patients, or PSP patients. When age was dichotomized at 55, 60, 65, or 70 years, the combined assessment of αSyn and Rab35 for classifying PD was better in the group below the cutof age than in the group above the cutof age. Conclusions Combined assessment of serum αSyn and Rab35 is a better biomarker for discriminating PD patients from NC or atypical parkinsonian patients, and is a useful predictive biomarker for younger sporadic PD patients.

Hsing-Hung Hsieh,Hsiung-Hsing Lu,Hung-Che Ting,Ching-Sang Chuang,Chia-Yu Chen,Yusin Lin 한국정보디스플레이학회 2010 Journal of information display Vol.11 No.4

Organic light-emitting devices (OLEDs) have shown superior characteristics and are expected to dominate the nextgeneration flat-panel displays. Active-matrix organic light-emitting diode (AMOLED) displays, however, have stringent demands on the performance of the backplane. In this paper, the development of thin-film transistors (TFTs) based on indium gallium zinc oxide (IGZO) on both Gen 1 and 6 glasses, and their decent characteristics, which meet the AMOLED requirements,are shown. Further, several display prototypes (e.g., 2.4” AMOLED, 2.4” transparent AMOLED, and 32” AMLCD) using IGZO TFTs are demonstrated to confirm that they can indeed be strong candidates for the next-generation TFT technology not only of AMOLED but also of AMLCD (active-matrix liquid crystal display)

Modeling/analysis of four-half axis machine tool via modified denavit-hartenberg notation

Chi-Kuei Sung,Chia-Hung Lu 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.12

Four-half axis and five-axis machine tools have five moving members (X, Y, Z, A, and B). Four-half axis systems cannot simultaneouslyoperate the B axis with translational or rotational axes, thus limiting tool machining ability and complicating NC codes. This studyemploys modified Denavit-Hartenberg notation to model four-half axis machine tool kinematics and obtain corresponding ability matrixes. NC data equations for the A, B, X, Y, and Z axes with respect to the workpiece frame are derived by inverse kinematics. Machinetool active parameters and workpiece home position are simultaneously measured by using a ball-end milling cutter as a measuring probe.

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.

Application of Near Infrared Spectroscopy, Digital Image, and Smell Sensor to Classify Quality for Taiwanese Pangola Hay

( Jhen-jia Guo ),( Ching-lu Hsieh ),( Ming-hung Chu ),( Chia-sheng Chen ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1

Hay quality is an important factor that affects yield and quality of animal products. It also influences its market price. Therefore, it is crucial to have quantitative value on hay quality. Conventionally hay quality is judged manually by its appearance, smell, and chemical composition that needs tedious laboratory analysis. Spectroscopy in near infrared, digital image technique, and electronic smell senor are techniques that have been broadly studied in agricultural field. They contain many advantages, such as, simple preparation for samples, non-destructive on samples, and quick detection. This study applied these three techniques in hay quality evaluation. Seventy Pangola hay samples were randomly collected from Kenting, a southern town in Taiwan. Each sample was scanned by a monochrometer (microPHAZER) to record its reflective spectrum at 1600~2400 nm. Its digital color image was taken by a commercial camera in a small chamber after a calibration process was performed. And the response curve of electric resistance change detected by three SiO₂ gas sensors of MQ5, TGS800, and TGS 822 were recorded for 15 minutes. These records were used to calibrate a prediction/classification model for hay quality evaluation. Among these sample data, 2/3 of them were used as calibration set while the rest were used as test set. For spectroscopy to predict composition, PLSR (Partial least square regression) and MLR (Multiple linear regression) models were tested to predict CP (Crude protein), NDF (Neutral detergent fiber) and ADF (Acid detergent fiber). Results showed the best model was found at PLSR that had correlation coefficient (R) on prediction and measurement on test set of 0.89, 0.80, and 0.71 for CP, NDF and ADF respectively and with RMSEP (root mean squared error of prediction) value of 1.04, 1.34, and 2.30. For digital image, expert score on each sample was calibrated with LDA (linear discriminant analysis) model and 79 features extracted from image were used. Results indicated that two groups classification accuracy was 100% in color for test set. For smell detection, four features were extracted from the response curve and LDA for two groups was tested. The classification accuracy was about 87% in test set. The study developed a GUI (Graphic user interface) to integrate these three quality evaluations for field application. In terms of contribution, this study developed a hay quality evaluation system that offers quick and nondestructive method. The system is portable and can be carried and operated in field.
