This paper presents indirect adaptive self-balancing and station keeping control methods using recurrent Wavelet Fuzzy CMAC (RWFCMAC) for an omnidirectional ball-driven chair in presence of significant system uncertainties. By backstepping, sliding-mode control and RWFCMAC, the self-balancing controller is synthesized to follow the rider’s inclination angles in both two axes (x-z and y-z axis), and the station-keeping controller is designed to allow the rider to maintain the vehicle at the same place. The RWFCMAC is designed to online learning the uncertainties caused by riders’ weights and different unknown frictions between the ball and terrain surfaces. The superior performance and merit of the proposed control methods are well exemplified by comparing to two existing controllers.

Chen Hsiao-Ching,Wang Jiun-Yi,Lee Ya-Chen,Yang Shang-Yu 한국산업안전보건공단 산업안전보건연구원 2023 Safety and health at work Vol.14 No.2

Background: The turnover rate of nurse aides in Taiwan is high. However, the predictors of turnover behavior in the newly employed are still unclear. Objective: To examine the predictors of turnover behavior in newly employed licensed nurse aides. Methods: A longitudinal study design was used and subjects were newly employed certified nurse aides from a nurse aid training association in Taiwan. A total of five questionnaire surveys were conducted. The questionnaire was mainly used to collect information on turnover behavior, personal socioeconomic background, workplace psychosocial hazards, worker health hazards, and musculoskeletal disorders. Results: A total of 300 participants were recruited in the study. Cox regression analysis results showed that short working experience (hazard ratio [HR] = 0.21, p < 0.01), work as non-home nurse aides (HR = 0.58, p = 0.01), low monthly salary (HR = 0.68, p < 0.01), high work mental load (HR = 1.01, p = 0.01), low workplace justice (HR = 0.97, p < 0.01), high workplace violence (HR = 1.60, p < 0.01), high burnout (HR = 1.01, p = 0.04), poor mental health (HR = 1.06, p = 0.04), and high total number of musculoskeletal disorder sites (HR = 1.08, p = 0.01) contribute to a higher risk of turnover. Conclusion: The results indicated that employment period, work as a home nurse aide, monthly salary, work mental load, workplace justice, workplace violence, work-related burnout, mental health, and total number of musculoskeletal disorder sites are predictors of turnover behavior in newly employed certified nurse aides.

새로운 다수제적 혼합제도에 대한 대만 시민의 인식도 -코호트 분석

( Chi Huang ),( Ching Hsin Yu ),( Yi Ching Hsiao ) 한국선거학회 2011 선거연구 Vol.1 No.2

선거제도는 투표를 의석으로 전환하는 규칙을 제공하며, 그에 따라 선거에서 누가 승리하고 패배하는가를 결정한다. 선거제도가 정치에서 수행하는 역할에 의문을 던지는 사람은 별로 없을 것이다. 그러나 기존 연구는 일반 시민들이 선거제도를 어떻게 인식하고 이해하고 있는가 (특히 선거제도가 근본적 변화를 경험하고 있는 이행기 동안에) 라는 질문에 대해서 이상하게도 침묵을 지키고 있다. 대만의 선거제도 개혁 경험은 이러한 빈 공간을 채울 수 있는 좋은 기회를 제공해 준다. 대만은 2008년에 의원 선거제도를 변화시켰는데, 지난 50년간 지속되어 왔던 단기비이양식(SNTV) 제도에서 다수제적 혼합선거제도 (MMM)로 바꿨다. 새로운 다수제적 혼합선거제도는 전체 의석 수, 선거구 크기, 선거 공식, 그리고 투표 구조 등에 있어서 과거의 단기비이양식 제도와 상당히 달랐다. 이 글은 새로운 선거제도를 소개하고 이 제도전반에 대한 시민들의 인식도를 알아보고자 한다. 또한 이 글에서는 시민들의 선거제도에 대한 지식이 2008년 선거 이전과 이후에 어떻게 변화했는지 살펴본다. 두 선거 제도 사이에 상당한 차이가 존재하기 때문에, 먼저 새로운 제도에 대한 시민들의 전반적 지식을 조사한다. 그 다음 설문조사 자료를 사용하여, 선거 기간과 비선거 기간 사이에 시민들의 지식 변화를 고찰한다. 분석 결과에 따르면, 다수의 시민들이 새로운 다수제적 혼합선거제도의 주요 구성 요인에 대해 완전히 이해하지 못하고 있다. 특히, 최소 조건에 대한 조항이 가장 적은 관심을 받고 있다. 더 나아가, 새로운 선거제도에 대한 시민들의 지식은 선거 모멘텀에 영향을 받아, 선거일이 다가옴에 따라 지식이 올라가고 선거일 이후에는 감소하는 것으로 나타났다. 마지막으로, 보다 구체적인 코호트 분석을 통해 시민들 중에 어떤 집단이 선거제도 변화와 관련된 정보를 가장 잘 획득하는지를 고찰한다. 본 연구 결과는 선거제도 지식에 대한 선거 주기 가설을 부분적으로 지지해준다. Electoral systems provide the rules of translating votes into seats and thus decide who wins and loses in elections. Few would doubt the critical roles that electoral systems play in politics. Yet current literature is curiously silent about how ordinary citizens perceive and understand the electoral system, especially during the transition period when the system is undergoing fundamental changes. The experiences of electoral reform in Taiwan provide an opportune case to fill up this gap. Taiwan transformed its legislative electoral system from a half-century long SNTV (single non-transferable vote) system to a MMM (mixed-member majoritarian) electoral system in 2008. The new MMM system is a sharp departure from the original SNTV system in the total number of legislative seats, the district magnitude, electoral formula, and ballot structure. This essay intends to introduce the new MMM system and explore citizens` awareness of the new MMM system in general. Also, it explores the changes of citizens` knowledge of the new electoral system before and after the 2008 legislative election. Given the significant differences between the SNTV system and the MMM system, it firstly tests of citizens` overall knowledge of the new MMM system. Then, with the help of survey data, it examines the changes of citizens` knowledge in election periods and non-election periods. The findings show a majority of citizens are not fully aware of the institutional components of the new MMM system. In particular, the threshold regulation receives the least attention by citizens. Furthermore, it finds that citizens` knowledge of the new MMM system is a function of electoral momentum, i.e., citizens` knowledge rises as the election date approaches and declines after the election date. Then we proceed with a more detailed cohort analyses to examine which groups of citizens are more likely to pick up information related to the electoral system changes. Our findings partially support our electoral cycle hypothesis of electoral system knowledge.

Aggravation of Hypertriglyceridemia and Acute Pancreatitis in a Bipolar Patient Treated with Quetiapine

Li-Syue Liou,Fone-Ching Hsiao,Yi-Jen Hung,Chang-Hsun Hsieh 연세대학교의과대학 2014 Yonsei medical journal Vol.55 No.3

Pancreatitis is a very rare adverse effect of quetiapine treatment, with only 5 cases of quetiapine-associated pancreatitis reported in the English literature to date. Herein, we report one patient who developed severe hypertriglyceridemia (>1000 mg/dL) after quetiapine administration, resulting in acute pancreatitis. An analysis of the underlying pathogenic mechanisms and a review of relevant literature are also presented. Clinicians should be aware of the potentially life-threatening metabolicdisturbances and/or pancreatitis associated with quetiapine therapy.

Does Spore Count Matter in Fungal Allergy?: The Role of Allergenic Fungal Species

Wan-Rou Lin,Yi-Hsing Chen,Mey-Fann Lee,Ling-Yi Hsu,Chih-Jen Tien,Feng-Ming Shih,Shih-Ching Hsiao,Pi-Han Wang 대한천식알레르기학회 2016 Allergy, Asthma & Immunology Research Vol.8 No.5

Purpose: Fungi have been known to be important aeroallergens for hundreds of years. Most studies have focused on total fungal concentration; however, the concentration of specific allergenic fungi may be more important on an individual basis. Methods: Ten fungal allergic patients and 2 non-fungal allergic patients were enrolled. The patients with a decrease in physician or patient global assessment by more than 50% of their personal best were considered to have an exacerbation of allergic symptoms and to be in the active stage. Those who maintained their physician and patient global assessment scores at their personal best for more than 3 months were considered to be in the inactive stage. The concentrations of dominant fungi in the patients’ houses and outdoors were measured by direct and viable counts at active and inactive stages. Results: The exacerbation of allergic symptoms was not correlated with total fungal spore concentration or the indoor/outdoor ratio (I/O). Specific fungi, such as Cladosporium oxysporum (C. oxyspurum), C. cladosporioides, and Aspergillus niger (A. niger), were found to be significantly higher concentrations in the active stage than in the inactive stage. Presumed allergenic spore concentration threshold levels were 100 CFU/m3 for C. oxysporum, and 10 CFU/m3 for A. niger, Penicillium brevicompactum and Penicillium oxalicum. Conclusions: The major factor causing exacerbation of allergic symptoms in established fungal allergic patients may be the spore concentration of specific allergenic fungi rather than the total fungal concentration. These results may be useful in making recommendations as regards environmental control for fungal allergic patients.

Who Wants Checks and Balances? Endogeneity of the Balancing Perspective

Yu, Eric Chen-Hua,Huang, Chi,Hsiao, Yi-Ching Center for Asian Public Opinion ResearchCollaborat 2015 Asian journal for public opinion research Vol.2 No.3

The premise of the intentional model of split-ticket voting is that some voters split their tickets simply because they prefer divided government and believe in constant "checks and balances." This article examines whether this premise stands firm in an emerging democracy like Taiwan. That is, by using survey data in Taiwan, we explore whether one's attitude toward divided or unified government is "real." We hypothesize that a citizen's attitude toward "checks and balances" is subject to change, and conditional on whether her preferred party is in power. Specifically, we speculate that a citizen would tend to hold the balancing perspective or favor divided government, if her preferred party is in opposition. However, if her preferred party becomes the ruling party, she would be more likely to oppose (hold) the balancing (non-balancing) perspective or favor unified government. We then utilize panel survey data embedded in Taiwan's Election and Democratization Studies (TEDS) to verify our hypothesis.

Comparison of Insulin Sensitivity, Glucose Sensitivity, and First Phase Insulin Secretion in Patients Treated with Repaglinide or Gliclazide

Chung-Ze Wu,Dee Pei,An-Tsz Hsieh,Kun Wang,Jiunn-Diann Lin,Li-Hsiu Lee,Yi-Min Chu,Fone-Ching Hsiao,Chun Pei,Te-Lin Hsia 대한약학회 2010 Archives of Pharmacal Research Vol.33 No.3

The traditional sulfonylureas with long half-lives have sustained stimulatory effects on insulin secretion compared to the short-acting insulin secretagogue. In this study, we used the frequently sampled intravenous glucose tolerance test (FSIGT) to evaluate the insulin sensitivity (IS), glucose sensitivity (SG), and acute insulin response after glucose load (AIRg) after 4months treatment with either gliclazide or repaglinide. The design of study was randomizedcrossover. We enrolled 20 patients with new-onset type 2 diabetes (mean age, 49.3 years). Totally three FSIGTs were performed, one before and one after each of the two treatment periods as aforementioned. No significant differences in fasting plasma glucose, insulin, body mass index, blood pressure, glycated hemoglobin, or lipids were noted between the two treatments. After the repaglinide treatment, higher AIRg, lower IS, and lower SG were noted, but they did not reach statistical significance. The disposal index (DI) was also not significantly different between the two treatments. In conclusion, since non-significantly higher DI, AIRg, lower IS and SG were noted after repaglinide treatment, it might be a better treatment for diabetes, relative to gliclazide.
