This study was designed to examine the prevalence and the risk factors of poor sleep quality in 4318 incoming university students in Taiwan. The test battery comprised a self-administered structured questionnaire, including items related to personal medical history and lifestyle habits, the Measurement of Support Functions (MSF), Pittsburgh Sleep Quality(More)
This study was designed to explore the risk factors of Internet addiction in 1360 freshmen of the National Cheng Kung University in Taiwan in 2003. The test battery included a self-administrated structured questionnaire, the Chinese Internet Addiction Scale-Revision (CIAS-R), the 12-item Chinese Health Questionnaire (CHQ-12), the Measurement of Support(More)
OBJECTIVES Although patients' social support is a critical factor for the prognosis of mental disorder treatments, biological mechanisms responsible for the impact of social support remain scarcely explored. We speculated that there may be an association between social support and central dopaminergic activities in humans. METHODS A total of 65 medicated(More)
The aims of this study were to investigate the economic costs of outpatients with schizophrenia in Taiwan, and to survey factors that influence the costs. The direct costs were defined as the costs associated with psychiatric services and other medical treatment. The indirect costs were estimated using the Human Capital Method. Patients' characteristics,(More)
Understanding hepatic zonation is important both for liver physiology and pathology. There is currently no effective systemic chemotherapy for human hepatocellular carcinoma (HCC) and its pathogenesis is of special interest. Genomic and proteomic data of HCC cells in different culture models, coupled to pathway-based analysis, can help identify HCC-related(More)
BACKGROUND Computational modeling of the absorption, distribution, metabolism, and excretion of chemicals is now theoretically able to describe metabolic interactions in realistic mixtures of tens to hundreds of substances. That framework awaits validation. OBJECTIVES Our objectives were to a) evaluate the conditions of application of such a framework, b)(More)
The aims of this study were: (i) to assess the impact of caring for patients with schizophrenia on the mental health status of the caregivers; and (ii) to examine the direct and buffer effects of social support on the mental health status of these caregivers. A total of 61 key caregivers of patients with schizophrenia were administered the Chinese Health(More)
FreeRTOS is an open-source real-time microkernel that has a wide community of users. We present the formal specification of the behaviour of the task part of FreeRTOS that deals with the creation, management, and scheduling of tasks using priority-based preemption. Our model is written in the Z notation, and we verify its consistency using the Z/Eves(More)
The Great Oxidation Event (GOE) ∼2.4 billion years ago resulted from the accumulation of oxygen by the ancestors of cyanobacteria [1-3]. Cyanobacteria continue to play a significant role in primary production [4] and in regulating the global marine and limnic nitrogen cycles [5, 6]. Relatively little is known, however, about the evolutionary history and(More)
Ancient transitions, such as between life that evolved in a reducing versus an oxidizing atmosphere precipitated by the Great Oxygenation Event (GOE) ca. 2.4 billion years ago, fundamentally altered the space in which prokaryotes could derive metabolic energy. Despite fundamental changes in Earth's redox state, there are very few comprehensive,(More)
