title: Factors Affecting Students' Continued Usage Intention Toward Business Simulation Games: An Empirical Study abstract: While the impact and value of simulation games have been investigated in the context of business and management education, few studies have investigated why students are willing to reuse the games or not. The main purpose of this study is to explore the determinants of students' continued usage intention for business simulation games in a higher education context based on the expectation-confirmation theory, flow theory, and motivation theory. Data collected from 381 valid respondents were used to test the research model using the partial least squares approach. The results of this study can provide several important theoretical and practical implications for educational use of business simulation games. The results indicate that continuance usage intention is influenced by learning satisfaction, which is in turn affected by perceived learning performance, learning confirmation, and learning expectation, and that learning confirmation is affected by learning expectation through the mediation of perceived learning performance. Additionally, perceived playfulness affects perceived learning performance while learning motivation influences learning expectation.
title: Developing a Mobile Electronic D2B Checklist for Treatment of ST Elevation Myocardial Infarction Patients Who Need a Primary Coronary Intervention abstract: ST elevation myocardial infarction (STEMI), one main type of acute myocardial infarction with high mortality, requires percutaneous coronary intervention (PCI) with balloon inflation. Current guidelines recommend a door-to-balloon (D2B) interval (i.e., starts with the patient's arrival in the emergency department and ends when PCI with a catheter guidewire and balloon inflation crosses the culprit lesion) of no more than 90 min. However, promptly implementing PCI requires coordinating various medical teams. Checklists can be used to ensure consistency and operating sequences when executing complex tasks in a clinical routine. Developing an effective D2B checklist would enhance the care of STEMI patients who need PCI. Mobile information and communication technologies have the potential to greatly improve communication, facilitate access to information, and eliminate duplicated documentation without the limitations of space and time. In a research project by the Chi Mei Medical Center, "Developing a Mobile Electronic D2B Checklist for Managing the Treatment of STEMI Patients Who Need Primary Coronary Intervention," a prototype version of a mobile checklist was developed. This study describes the research project and the four phases of the system development life cycle, comprising system planning and selection, analysis, design, and implementation and operation. Face-to-face interviews with 16 potential users were conducted and revealed highly positive user perception and use intention toward the prototype. Discussion and directions for future research are also presented.
title: Exploring critical factors influencing physicians' acceptance of mobile electronic medical records based on the dual-factor model: a validation in Taiwan abstract: Background: With respect to information management, most of the previous studies on the acceptance of healthcare information technologies were analyzed from "positive" perspectives. However, such acceptance is always influenced by both positive and negative factors and it is necessary to validate both in order to get a complete understanding. This study aims to explore physicians' acceptance of mobile electronic medical records based on the dual-factor model, which is comprised of inhibitors and enablers, to explain an individual's technology usage. Following an earlier healthcare study in the USA, the researchers conducted a similar survey for an Eastern country (Taiwan) to validate whether perceived threat to professional autonomy acts as a critical inhibitor. In addition, perceived mobility, which is regarded as a critical feature of mobile services, was also evaluated as a common antecedent variable in the model.
Methods: Physicians from three branch hospitals of a medical group were invited to participate and complete questionnaires. Partial least squares, a structural equation modeling technique, was used to evaluate the proposed model for explanatory power and hypotheses testing.
Results: 158 valid questionnaires were collected, yielding a response rate of 33.40%. As expected, the inhibitor of perceived threat has a significant impact on the physicians' perceptions of usefulness as well as their intention to use. The enablers of perceived ease of use and perceived usefulness were also significant. In addition, as expected, perceived mobility was confirmed to have a significant impact on perceived ease of use, perceived usefulness and perceived threat.
Conclusions: It was confirmed that the dual-factor model is a comprehensive method for exploring the acceptance of healthcare information technologies, both in Western and Eastern countries. Furthermore, perceived mobility was proven to be an effective antecedent variable in the model. The researchers believe that the results of this study will contribute to the research on the acceptance of healthcare information technologies, particularly with regards to mobile electronic medical records, based on the dual-factor viewpoints of academia and practice.
title: Extending ict4d studies: the value of critical research abstract: The purpose of this paper is to demonstrate the value of critical research for information and communications technology for development (ICT4D) studies. Most previous IS research on ICT4D projects is interpretive and has focused on the immediate organizational context, but there are very few critical studies that have engaged in macro sociopolitical analyses regarding institutional change. Hence we extend previous IS research on ICT4D by adopting a critical research perspective on the macro sociopolitical context within which most ICT4D projects take place. We illustrate this with an ethnographic study of a project that was intended to improve the education and social welfare of the aboriginal people in Taiwan. On the surface the project was tremendously successful; it became a showcase on national radio and TV showing how ICT could be used to support underprivileged children. However, our research uncovered a different story altogether-a story of the aboriginal people themselves feeling marginalized and without much of a voice. We use concepts from postcolonial theory to make sense of these two contradictory stories. We found that the interrelationship between the macro sociopolitical context and the local organizational context of the ICT4D project is the key to understanding what went wrong, something which we would not have discovered if we had taken the traditional approach. The postcolonial context is powerful and pervasive, hampering any real progress.
title: Cost-effectiveness of Gemcitabine Plus Modern Radiotherapy in Locally Advanced Pancreatic Cancer abstract: Purpose: The purpose of this study was to evaluate the cost-effectiveness of gemcitabine plus modern radiotherapy versus gemcitabine alone in the treatment of locally advanced pancreatic cancer in Taiwan. Methods: A Markov decision-analytic model was performed to compare the cost-effectiveness of 3 treatment regimens; gemcitabine alone (gem-alone), gemcitabine plus intensity-modulated radiotherapy (gem-IMRT), and gemcitabine plus stereotactic body radiotherapy (gem-SBRT). Patients transitioned between 5 health states: stable disease, local progression, distant metastasis, local and distant metastasis, and death. Findings: The incremental cost-effectiveness ratio for gem-IMRT and gem-SBRT compared with gem alone were NT$27,120,168 and NT$2,145,683 per quality-adjusted life-year gained, respectively. A willingness to pay threshold of 3 times the per capita gross domestic product was adopted according to the definition of the World Health Organization. The Taiwan per capita gross domestic product in 2015 was NT$673,920 (US$22,464; 1 NT$ = US$0.03333 in Taiwan); thus, a threshold was considered as NT $2,021,760 (US$67,392). The Monte-Carlo simulation found that the probability of cost-effectiveness at a willingness to pay threshold of NT$2,021,760 per quality-adjusted life-year was 0% chance for gem-IMRT and 50% for gem-SBRT. Implications: This study indicated that gem-IMRT or gem-SBRT in locally advanced pancreatic cancer is not cost-effective at a willingness to pay as defined by World Health Organization guideline in Taiwan.

title: Control System Using Multithread and Stereo Vision to Tracking Target abstract: This article proposes a more effective, the vision track control method for main objective increase system performance. Using multithread processing can improve the regulations monitor and quickly locked in tracking goals. In a stereo Visual Act establishes both the webcam and send images data to the calculator, is calculator multithread application control system. The main purpose of this paper is in its procedures for tracking and servo control system used in the line of control. Using strereo vision impact modifier of the head of the movement. System platforms and the precise distance between objects can be adjusted through good binocular focus and got to find this picture of a monocular distance algorithm was solved. This approach shows that when a body was identified at the center of this image, images can be applied to correct the error of the servo motor. If it can be put on to a single location, this unilateral approach will also be used to estimate the actions. In this paper compares with single thread to multithread, multithread improves tracking pace and stabilizes time [1-3], especially vision Tracking and servo control will have a large number of materials, take to improve the system.
title: Development of a situational initiation training program for preceptors to retain new graduate nurses: Process and initial outcomes abstract: Background: Most preceptor training programs consist of classroom-based courses, and only a few programs are conducted using films. Preceptors have identified most training courses as inapplicable in various clinical situations. Objectives: To describe the systematic development of a situational initiation training program (SITP) for preceptors and to evaluate its impacts on the stress levels of preceptors and new graduate nurses (NGNs), the preceptor-NGN relationship, support provided by preceptors to NGNs, and the intention to leave among NGNs during a 1-year preceptorship. Design: The conceptual framework of development, implementation, and evaluation was used for program completion. Participants and Settings: Preceptors and NGNs working at a teaching medical center in Taipei participated. Methods: The 1-day SITP workshop comprised four films, reflection time, and four classroom-based courses. Training outcomes were evaluated using a questionnaire survey for preceptors and NGNs at months 3, 6, 9, and 12 after employing the NGNs. Data were analyzed using descriptive statistics and analysis of variance with repeated measures. Results: The annual turnover rate of NGNs was 10.5%. During the first preceptorship year, the NGNs reported moderate stress levels, good to excellent relationships with their preceptors, moderate to excellent support from their preceptors, and low intention to leave their current jobs. Similarly, preceptors reported moderate stress levels, except at month 12 (mean = 4.8), and good to excellent relationships with their NGNs. The SITP considerably improved the preceptor-NGN relationship for both NGNs and preceptors, whereas no improvement was observed in the stress levels, except in the stress levels of preceptors. Conclusions: The SITP is clinically effective for preceptors; thus, nurse educators may apply the SITP for redesigning the existing preceptor training programs to develop highly skilled preceptors and improve training outcomes.

title: Glutamine in Alleviation of Radiation-Induced Severe Oral Mucositis: A Meta-Analysis abstract: The aim of this meta-analysis was to assess the effectiveness of glutamine to treat severe mucositis induced by radiation therapy in patients with head and neck cancer. We undertook electronic searches of PubMed (1990 to January 2015), Embase (1990 to January 2015), and the Cochrane Library (2013, Issue 2) to identify relevant studies. We included randomized controlled trials of glutamine to alleviate oral mucositis (OM) in patients with head and neck cancer who received radiotherapy. Information regarding methods, patients, results, and risk of bias was independently extracted by two authors. Statistical analyses were conducted to calculate the odds ratio and 95% confidence intervals (95%CIs) using fixed-effect models. We identified five clinical studies that included 234 patients with head and neck cancer. All studies were assessed as being at low risk of bias in most items of six domains. In this meta-analysis, glutamine treatment showed a statistically significant benefit with respect to reducing the risk and severity of OM induced by radiotherapy compared to either placebo or no treatment (risk ratio 0.17, 95%CI 0.06-0.47). Overall, glutamine significantly reduces the risk and severity of OM during radiotherapy or chemotherapy. Further prospective and large trials are required to support the findings.
title: Vitamin D3 Intake Dose and Common Cancer: A Population-Based Case Control Study in a Chinese Population abstract: Objectives: Epidemiological studies suggest that vitamin D status is associated inversely with risk of common cancers in western populations. This study aimed to investigate whether vitamin D is associated with risk of common cancers in Chinese population. Methods: A population-based retrospective case-control study was conducted analyzing data retrieved from the Catastrophic Illness Patient Databases (CIPD) and longitudinal health insurance database (LHID) from January 1, 2010 to December 31, 2011 and January 1, 2000 to December 31, 2011, respectively. Cases were identified as subjects diagnosed with site-specific cancers (International Classification of Diseases, Ninth Revision,) and frequency matched to select controls. Use of vitamin D3 was compared between two groups. Odds ratios (ORs) were employed to quantify the risk associated with exposure to vitamin D3 by logistic regression. Results: There were 1.21% (1961/161806) patients in cases and 0.67 % (1092/161806) patients in controls identified were vitamin D3 users. Overall risk of cancers associated with vitamin D3 users was 1.67 (95% CI: 1.55 -1.81). Among these, the risk of kidney cancer and bladder cancer associated with intakes of vitamin D3 were significant (OR 2.59; 95% CI 1.81-3.70; OR 4.97; 95% CI 4.40-5.60) in an adjusted model. In further stratification analysis, we found a statistically significant risk of bladder cancer associated with high intake of vitamin D3. Except this, no statistically significant risk of other site-specific cancers associated with high intake of vitamin D3. Conclusion: Except bladder cancer in stratification analysis, we observed no statistically significant association between high intake of vitamin D3 and other site-specific cancers.
