Pneumothorax is a potentially lethal complication associated with mechanical ventilation. Most of the patients with pneumothorax from mechanical ventilation have underlying lung diseases; pneumothorax is rare in intubated patients with normal lungs. Tension pneumothorax is more common in ventilated patients with prompt recognition and treatment of pneumothorax being important to minimize morbidity and mortality. Underlying lung diseases are associated with ventilatorrelated pneumothorax with pneumothoraces occurring most commonly during the early phase of mechanical ventilation. The diagnosis of pneumothorax in critical illness is established from the patients' history, physical examination and radiological investigation, although the appearances of a pneumothorax on a supine radiograph may be different from the classic appearance on an erect radiograph. For this reason, ultrasonography is beneficial for excluding the diagnosis of pneumothorax. Respiration-dependent movement of the visceral pleura and lung surface with respect to the parietal pleura and chest wall can be easily visualized with transthoracic sonography given that the presence of air in the pleural space prevents sonographic visualization of visceral pleura movements. Mechanically ventilated patients with a pneumothorax require tube thoracostomy placement because of the high risk of tension pneumothorax. Small-bore catheters are now preferred in the majority of ventilated patients. Furthermore, if there are clinical signs of a tension pneumothorax, emergency needle decompression followed by tube thoracostomy is widely advocated. Patients with pneumothorax related to mechanical ventilation who have tension pneumothorax, a higher acute physiology and chronic health evaluation Ⅱ score or Pa O2/Fi O2 < 200 mm Hg were found to have higher mortality.

Background The ＂National＂ Health Insurance （NHI） in Taiwan, china is a single-payer system that was introduced in 1995 to provide universal health care. It is worth noting that three stakeholders are involved in Taiwan＇s NHI, which can be seen as a triangular governance regime between the Bureau of ＂National＂ Health Insurance （BNHI）, the insured and providers. Accordingly, this study intended to assess the efficiency of various different production processes that occur among these stakeholders in Taiwan＇s NHI system. Methods A two-stage relational Data Envelopment Analysis （DEA） model is adopted to investigate the sub-process efficiencies of the health care resources held by 23 cities and counties through stages I or II, where the outputs of the first stage serve the inputs of the second. The dataset was collected from the annual reports published by the Department of Health, Taiwan, china. Results Under the proposed framework, the efficiency of the whole process can be obtained from the product of productivity and allocative efficiency. Ten DMUs are efficient either in stages I or II, with only two DMUs being efficient with regard to both sub-processes. Conclusion The relational DEA model not only demonstrates the physical relationship between the whole process and the sub-process components, but also produces reliable outcomes in efficiency measurement among different stakeholders in Taiwan＇s NHI system.

Emperor Tuoba Hong 1) of Beiwei relocated the capital from Pingcheng to Luoyang approximately 1500 years ago. Most historians speculate that his motivation was based on considerations of politics, economics, military, history, and chinese culture. However, Sima Guang, a famous historian during the Song Dynasty, claimed 1000 years ago that cold climate was the cause of this historical event. In order to assess the credibility of Sima Guang’s claim, this research examines related ancient documents and the recent frost data for a comparative study. It is found that the mean minimum temperature in Pingcheng during 479AD～509AD is estimated to be lower than present minimum temperature by 2.48 ℃ .

The metal atom net charge correlation(MANCC) method was developed in prediction of catalyst activity of asymmetric late-transition metal complexes,2-quinoxalinyl-6-iminopyridine Ni(Ⅱ),2-imino-1,10-phenanthroline Co(Ⅱ) and 2-methoxycarbonyl-6-iminopyridine Pd(Ⅱ) complexes,from the net charge of the metal atom for ethylene *** force field was modified according to the X-ray diffraction *** found that the asymmetric structure of the complexes resulted in a charge differ-ence between two halogen atoms coordinated to the metal *** order to remove such contribution we introduced the effective charge Qeff,which was obtained by the charge equilibration(QEq) *** results verified the successful introduction of Qeff and showed that the catalytic activities of different complexes are related to central metal atom effective charge.

We discuss a unified model of quark confinement and new cosmic expansion with linear potentials based on a general（SU3）color×（U1）baryon symmetry. The phase functions in the usual gauge transformations are generalized to new ‘action integrals＇. The general Yang-Mills transformations have group properties and reduce to usual gauge transformations in special cases. Both quarks and ‘gauge bosons＇ are permanently confined by linear potentials. In this unified model of particle-cosmology, physics in the largest cosmos and that in the smallest quark system appear to both be dictated by the general Yang-Mills symmetry and characterized by a universal length. The basic force between two baryons is independent of distance. However, the cosmic repulsive force exerted on a baryonic supernova by a uniform sphere of galaxies is proportional to the distance from the center of the sphere. The new general YangMills field may give a field-theoretic explanation of the accelerated cosmic expansion. The prediction could be tested experimentally by measuring the frequency shifts of supernovae at different distances.

The compressive and tensile strain rate sensitivities of polycrystalline and single crystal NiAl have been evaluated at 877 ℃ which is well above DBTT. Samples were prepared to specific sizes by hot press consolidation of appropriate powder sizes and minimizing past consolidation thermal exposures. NiAl single crystals were grown in the [100]orientation using a modified Bridgeman technique. The yield and tensile strength of polycrystalline NiAl as a function of grain size generally follows a Hall-Petch type relationship . A tensile strain rate effect was found at strain rate of 1 to 10-4 sec-1. The strain rate sensitivity coefficient, m,in the equation of σ = Kε is in the range of 0. 10 to 0. 13. The highest strain rate (1 sec-1) resulted in significantly higher strengths and little or no observed ductility. Compressive strain rate testing al strain rate of 10-5to 10-2 sec-1 and at temperature of 1050°to 1250°K was conducted both for polycrystalline and for single crystal NiAl. The calculated stress exponents and the activation energy for creep were compared with the reference data.
