A preliminary comparative analysis of 3D body scanner,manually taken girth body measurements and size chart measurements

In an attempt to provide a technological solution to the influx of cheap imports in South Africa and bridging the technology divide between Africa and the rest of the world, the Council for Scientific and Industrial Research procured a three‐dimensional body scanner from the Textile and Clothing Technology Corporation, in the US. The pilot study was aimed at introducing the technology to the South African consumers, and to compare the scanned data with the manually taken measurements. A convenience sample of 56 females in South Africa was interviewed using a structured questionnaire. Interviews were used to capture views on acceptance of the technology, prior to being scanned. Scanning garments made from a stretchy fabric were designed and sewn in four sizes of small, medium, large and extra large. A covariance, one sample t‐test and paired t‐ tests were used for data analyses. Almost all respondents felt comfortable with the designed scanning garments and the scanning process. The scanner measurements were generally more numerical in value than the manual measurements for a body part as expected, although the disparity was on the higher side than expected. The discernible difference between means of scanned data and standard values in the currently used sizing charts highlighted the long overdue need to update the sizing charts using a national anthropometric database generated locally.     

A LONG‐RUN VIEW OF THE UNIVERSITY GENDER GAP IN AUSTRALIA*

Australian universities were first established in the 1850s, well before the introduction of compulsory schooling. From the middle of the twentieth century, the introduction of mass secondary school education and the expansion of the number of universities widened student access to universities. Subjects offered in higher education increased in scope and labour market discrimination diminished. These factors, together with supply‐side changes, meant that women were more easily able to shift into investing in skills. By 1987, Australian women were more likely than men to be enrolled at a university. These aggregate figures, however, disguise considerable heterogeneity across fields of study.

表面包覆Y（OH）3对BAM蓝色荧光粉性能的影响

采用化学共沉淀法对BaMgAl10O17：Eu2＋（BAM）粉体进行表面包膜处理，获得了表面均匀包覆Y（OH）。膜层的BAM荧光粉，并用SEM、XRD和粒度仪对其表面形貌、晶格结构性能进行了表征，用荧光光谱测试对荧光粉的发光性能进行了研究．结果表明：在BAM粉体表面均匀包覆Y（OH）3层后，BAM的晶格结构、发光性能没有改变，初始亮度较未包覆的荧光粉有所降低，经过相同条件的热处理后，包覆Y（OH）3荧光粉的亮度热衰减程度明显低于未包覆的荧光粉．
