Digital infrared thermography is suitable for monitoring the planar two-dimensional temperature distribution of curved surfaces of objects by sensing their infrared radiation. Cardiac infrared thermography also has a thermal coronary angiography alias. This study proposes a digital image processing methodology for locating blood clot blockage. This methodology contains four consequent processes. The two-dimensional gray scale infrared thermograph pixels are first binarized and classified as background or coronary arteries using multi-thresh adaptive *** coronary artery contours are extracted from segmented raw pixels using continuous pepper-like pixel removal,erosion,subtraction,recursive neighborhood visiting,contour point-list construction and short edge *** the third process one coronary artery branch is selected by physicians for calculating the longest curved central axis using morphological thinning and neighborhood analysis. In the last process the nearest left and right distances from each pixel along the directional central axis to its corresponding boundary contour are added as the coronary artery variable diameter at the current pixel's position. A variable diameter versus straighten length diagram along this axial curved path is plotted to provide useful physiological information to the physician. An obstruction rate equation is then defined to calculate the possible vascular blockage positions with the local minimal rates. Finally,preoperative cases are tested to prove the predictive positions are correct in comparison to individual patient myocardial perfusion imaging.

This study investigated the microstructural characteristics, metallurgy, microhardness, and tensile strength of AZ31 and AZ61 magnesium alloy weldments, fabricated in a CO2 laser welding process with the adjustment of various parameters. The results show that the AZ31 weldment contains equiaxed grains within the fusion zone （FZ）. By contrast, the FZ of the AZ61 weldment contains refined cellular grains and the partially melted zone （PMZ） contains bulk grains. We infer that the difference in aluminum content between the two magne-sium alloys results in different supercooling rates and solid grain structures. For both weldments, the ultimate tensile strength （UTS） de-creases following the CO2 laser welding process. However, no significant difference is noted between the UTS of the two weldments, sug-gesting that tensile strength is insensitive to the Al content of the magnesium alloy. The CO2 laser welding process is shown to increase the microhardness of both magnesium alloys. Furthermore, grain refinement is responsible for the maximum hardness in the FZ of both weld-ments. The AZ61 weldment has a higher content of Al, resulting in a greater grain refinement.

洒水控制对钢铁厂原料堆场逸散扬尘的影响

选定中国钢铁公司厂内3种不同的原料堆场（煤料、石料与铁矿），分别就其洒水控制前后进行逸散扬尘的采样分析并探讨其变化。使用滤纸匣采样器吊挂于不同高程来替代一般地面上的总悬浮颗粒物（TSP）高量采样器进行现场采样。结果显示：就原料堆场风蚀作用所致逸散扬尘量而言，洒水后的扬尘控制效率分别为煤料的34．42％、石料的48．62％以及铁矿的66．81％；得知洒水对于风蚀扬尘的控制以铁矿为最佳，其次为石料，而煤料则最低。而物理成分分析结果显示，洒水后煤料所含的黏土含量及含水量均较铁矿与石料为高。另外，由于其喷洒水源使用的是厂内再生水，有可能因再生水的成分造成洒水后的逸散扬尘组成分起到变化。针对再生水与扬尘进行离子成分分析，结果发现洒水后，煤料中水溶性离子浓度有明显上升趋势；石料除了Mg^2＋及Ca^2＋浓度变化不大外，其余亦有明显上升的趋势；铁矿则与煤料有类似的情形。证实了喷洒再生水对扬尘中离子浓度的上升产生一定程度的影响。

AIM To investigate the association between cardiorespiratory fitness and hospitalization events in a cohort of large voluntary arm forces in Taiwan. METHODS The cardiorespiratory fitness and hospitalization events in armed forces(CHIEF) is a retrospective cohort consisting of more than 4000 professional military members aged 18-50 years in Eastern Taiwan. All participants received history taking, physical examination, chest radiography, 12-lead electrocardiography, blood tests for cell counts and fasting glucose, lipid profiles, uric acid, renal function and liver function in the Hualien Armed Forces General Hospital during 2014. In addition, participants were required to undergo two indoor resistant exercise tests including 2-min push-up and 2-min sit-up, both scored by infrared sensing, and one outdoor endurance 3000-m none weight-bearing running test, the main indicator of cardiorespiratory fitness in the Military Physical Training and Testing Center in Eastern Taiwan in 2014. RESULTS Hospitalization events for cardiovascular disease, acute kidney injury, rhabdomyolysis, severe infectious disease, acute psychiatric illness, diabetes, orthopedic surgery and mortality will be identified in the National Insurance Research Database for 10 years. CONCLUSION CHIEF will be among the largest Eastern Asian armed forces cohort, in which physical status was strictly evaluated to follow up the hospitalization events for severe illness.
