    Coronary artery bypass grafting surgery (CABG) is a stressful event and requires coping strategies to achieve adaptation. In Taiwan, despite the fact that the incidence of CABG is increasing in both men and women, research on post-CABG adaptation is very limited and no research focuses on outcomes for women. This can lead to problems for health care providers who lack effective interventions to help these patients. The purpose of the study was to examine the relationship between coping, anxiety, and quality of life in Taiwanese post-CABG patients. A cross-sectional correlational design was used; the sample consisted of 50 female and 50 male patients. A post-hoc analysis was employed to understand whether the patients understood the words used in the instruments. To provide more depth to the findings, semi-structured interviews with three male and three female participants were conducted. The literature indicated that the variables\u27 effect on quality of life varied across studies. In the present study, ways of coping, anxiety, and quality of life interacted and influenced each other. Post-CABG patients who were male and had more role responsibility, experienced lower levels of anxiety and used problem-focused coping; as a result, were more likely to obtain a better quality of life. Anxiety was a good predictor of adaptation outcome and was negatively associated with problem-focused coping. Additionally, mental health predicted greater use of problem-focused coping. The results of the semi-structured interview indicated that the quantitative findings were valid and reliable. Men still adapted better than did the women. Both men and women were concerned about their physical recovery following CABG, but men tended to make plans to take control of their health, while women tended to seek help to overcome their stress. The semi-structured interviews provided richness to the study that could not have been captured by quantitative findings alone. The interview responses raised questions about the effect of personality, worldview, culture, anxiety, coping, and perceptions on quality of life that need to be further explored

    [[abstract]]To determine the role of adherence and its significance in the relationship between self-efficacy and self-management of diabetic patients undergoing coronary artery bypass graft (CABG) in Taiwan. Descriptive and correlational survey design. Three outpatient clinics in Taiwan. Patients diagnosed with diabetes undergoing CABG at least 6 months before the study, 18 years of age or older, able to communicate verbally without any psychiatric problems, and with a life expectancy longer than 1 year. Self-management assessment (self-efficacy for managing disease and adherence to guidelines and medication measured on a scale of 0-8), the higher aspects of self-management (keeping appointments, taking medication properly and keeping follow-up appointments) and the lower aspects of self-management (inability to share decisions with primary physician, inability to take correct actions when symptoms worsen and inability to adapt habits to improve health). The mean score obtained for self-management among the 166 participants was 6.48, with 57 (34.3%) of them showing non-adherent behaviour. Self-efficacy accounts for 38% (R(2)=0.380, F(1,103)=63.124, p < 0.001), and 54% of good self-management was explained by self-efficacy and adherence in managing disease (R(2)=0.540, F(2,102)=56.937, p<0.001). Adherence accounts for 16% of better self-management, age and education combined account for 4.9% (R(2)=0.589, F(6.98)=23.399, p<0.001), and lifestyle items account for 5.2% (R(2)=0.641, F(14,90)=11.457, p<0.001). Disease-related variables contribute 3.4% (R(2)=0.674, F(17,87)=10.599, p<0.001). Thus self-efficacy, adherence, age, education, primary care provider and systolic pressure are considered significant predictors of self-management. With the exception of adherence, none of the variables had a statistically significant mediating effect. The results confirm strong relationships between self-efficacy, adherence and self-management, with adherence having a significant mediating effect in post-CABG patients with diabetes in Taiwan.

    Purpose. To evaluate sex-related differences in the prevalence of and cardiovascular risk factors related to gallstone disease (GSD) in an elderly agricultural and fishing population of Taipei, Taiwan. Methods. The study sample consisted of 6511 healthy elderly participants (3971 men and 2540 women) who were voluntarily admitted to a teaching hospital for a physical checkup in 2010. The participants’ blood samples and real-time ultrasound fatty liver results were collected. Results. The prevalence of GSD in the study population was 13.2%, which increased significantly with population age (P<.0001). Women were associated with significantly higher GSD prevalence than men (14.8% versus 12.2%; for the chi-square test, P=.003). In a multiple logistic regression analysis, female sex, older age, and metabolic syndrome (MetS) were significantly associated with GSD. Multiple logistic regression analysis also revealed that obesity (odds ratio OR=1.26, 95% confidence interval (CI): 1.09–1.44) and metabolic factors (one or 2 versus none, OR=1.48, 95% CI: 1.08–1.76) were significantly associated with GSD in women but not in men. Conclusion. In the study population, female sex, older age, and MetS were associated with higher GSD prevalence. The population exhibited other sex-related differences

    To realize the plate motion of the Philippine Sea Plate (PSP) and the characteristics of crustal deformation in the plate boundary zone between the PSP and Eurasia Plate, three seafloor geodetic arrays using a combination of GPS kinematic positioning and acoustic ranging techniques have been established off eastern Taiwan since 2008. Each array is composed of three transponders deployed on the ocean bottom in a triangular shape and has been observed at least two times since 2009. The GPS kinematic positioning in the relative distance ranging from 80 to 120 km off the eastern coast of Taiwan plays a main role in the whole seafloor geodetic deformation system. Seven stations from Taiwan Continuous GPS Array are taken as reference sites and three or four rover GPS units are set up on the vessel or buoy. Both on-land reference and onboard rover receivers record data in sampling rates of 1 and 5 Hz to determine the instantaneous positions of transducer onboard which transmits and receives the acoustic signal to and from seafloor transponders and the attitude of vessel or buoy in kinematic mode. We compare the results of medium-range kinematic positioning between the on-land reference stations and rovers onboard by the GrafNav and Bernese V5.0 software, respectively. In addition, we determine the attitude at all times by way of computing the inter-distance of rover receivers onboard. Hence there are two positioning results can be estimated which are direct (by short relative distances from onboard) and indirect (by medium-range kinematic mode for each GPS unit from on-land continuous stations) methods, and the difference reveals in decimeter level

    CFVS: Coarse-to-Fine Visual Servoing for 6-DoF Object-Agnostic Peg-In-Hole Assembly

    Robotic peg-in-hole assembly remains a challenging task due to its high accuracy demand. Previous work tends to simplify the problem by restricting the degree of freedom of the end-effector, or limiting the distance between the target and the initial pose position, which prevents them from being deployed in real-world manufacturing. Thus, we present a Coarse-to-Fine Visual Servoing (CFVS) peg-in-hole method, achieving 6-DoF end-effector motion control based on 3D visual feedback. CFVS can handle arbitrary tilt angles and large initial alignment errors through a fast pose estimation before refinement. Furthermore, by introducing a confidence map to ignore the irrelevant contour of objects, CFVS is robust against noise and can deal with various targets beyond training data. Extensive experiments show CFVS outperforms state-of-the-art methods and obtains 100%, 91%, and 82% average success rates in 3-DoF, 4-DoF, and 6-DoF peg-in-hole, respectively

    Thoracic cancer treatment presents dosimetric difficulties due to respiratory motion and lung inhomogeneity. Monte Carlo and deformable image registration techniques have been proposed to be used in four-dimensional (4D) dose calculations to overcome the difficulties. This study validates the 4D Monte Carlo dosimetry with measurement, compares 4D dosimetry of different tumor sizes and tumor motion ranges, and demonstrates differences of dose-volume histograms (DVH) with the number of respiratory phases that are included in 4D dosimetry. BEAMnrc was used in dose calculations while an optical flow algorithm was used in deformable image registration and dose mapping. Calculated and measured doses of a moving phantom agreed within 3% at the center of the moving gross tumor volumes (GTV). 4D CT image sets of lung cancer cases were used in the analysis of 4D dosimetry. For a small tumor (12.5 cm3) with motion range of 1.5 cm, reduced tumor volume coverage was observed in the 4D dose with a beam margin of 1 cm. For large tumors and tumors with small motion range (around 1 cm), the 4D dosimetry did not differ appreciably from the static plans. The dose-volume histogram (DVH) analysis shows that the inclusion of only extreme respiratory phases in 4D dosimetry is a reasonable approximation of all-phase inclusion for lung cancer cases similar to the ones studied, which reduces the calculation in 4D dosimetry
