泰山历史文化轴景观空间特色研究

泰山作为世界自然与文化的双重遗产,古今中外的学者对泰山做了深入而细致的研究,而对泰山历史轴的研究却很少。泰山历史文化轴是连接山城一体的景观轴线,同时也是展现泰安古城"三重空间"的精华地段。文章基于景观空间要素中的点、线、面、体的概念,针对泰山历史文化轴相对应的空间要素、空间序列、空间地形以及空间意境上进行分析,进而总结出其在构成山城景观空间的艺术特点。

在博物馆规划中如何融入地域文化景观——以海峡两岸中医药博物馆修建性详细规划为例

城市自身的地域特征和地方历史文化特色是城市的灵魂.博物馆区是体现城市地域文化景观的重要载体.保生大帝信仰是以厦门、漳州、泉州为基点向台湾、东南亚地区传播的主要地域文化和民俗文化.文章以海峡两岸中医药博物馆修建性详细规划为例,初步探索了博物馆区规划设计中融入地域文化景观的方法.主要论述观点有：以弘扬本土文化,促进两岸交流作为规划理念,并将理念贯穿于整个规划中;提出博物馆区与慈济东宫景区的文化和自然背景相互协调的措施;创造性发展闽南民居风格的特色建筑;构建地域性特色的景观环境.     

Comparison of particle-phase polycyclic aromatic hydrocarbons and their variability causes in the ambient air in Ho Chi Minh City, Vietnam and in Osaka, Japan, during 2005-2006

A comparative study of polycyclic aromatic hydrocarbons (PAHs) associated with particulate matter (TSP) in the ambient air in an urban area in Ho Chi Minh City, Vietnam and in Osaka, Japan was carried out from 2005 to 2006. The objective of this study was to investigate the environmental levels, emission sources, seasonal variations and health risk of eleven PAHs in the two cities, especially Ho Chi Minh City where air pollution is becoming a serious concern. The results showed that the concentrations of TSP and total PAHs were significantly higher in Ho Chi Minh City than levels in Osaka. The concentrations of 5- and 6-ring PAHs (BeP, BbF, BkF, BaP, BghiP and InP) were much higher in TSP samples in Ho Chi Minh City than in Osaka, accounting for 82% and 51% of total PAHs, respectively. These PAHs are known to be highly carcinogenic and mutagenic in humans. Vehicular emission is suggested as one of the main pollution sources of PAHs in both cities. Motorcycles and gasoline automobiles are suggested as the main emission sources of PAHs in Ho Chi Minh City, whereas diesel automobiles are the primary source in Osaka. Seasonal variations of PAHs were observed in this study; higher concentrations of PAHs were found in the rainy season (May-December) and lower concentrations corresponded to the dry season (February-April) in Ho Chi Minh City, while higher concentrations of PAHs were observed in the winter (November-January) in Osaka. The number of sunshine hours was an important meteorological factor affecting seasonal variations of PAHs in Ho Chi Minh City, while the temperature was a main factor causing the variations of PAHs in Osaka. The high BaP equivalent concentration of 5- and 6-ring PAHs even in the ambient air is an alarming signal for harmfulness to human health and environmental quality in Ho Chi Minh City.     

利用异或运算和编码约束的降维LDP人脸识别方法

为了有效表示面部特征,在局部方向模式(LDP)的基础上,提出降维局部方向模式(RDLDP)；首先,修改LDP编码模式约束以完成模式的重构,通过对LDP码进行异或运算来计算每个块的单一码；然后,将所得编码图像划分为生成直方图,连接所有区域的直方图块以形成最终描述符;最后,计算特征向量间的卡方相异性度量值,并使用最近邻分类器完成最终的人脸识别;实验采用了3个公开的标准数据库FERET、扩展YALE-B和ORL,提出的改进方法在3个数据集上的最高识别率分别可高达96.97%、96.10%、97.61%,该结果验证了提出方法的有效性。与其他基于局部描述符的先进方法相比,提出方法在准确度和错误识别率等方面更优。     

Food safety knowledge,attitudes and practices of street food vendors and consumers in Ho Chi Minh city,Vietnam

This study had the major objective of evaluating the food safety knowledge, attitudes and practices of consumers and vendors of street foods in Ho Chi Minh City (MCMC), Vietnam. There were three main surveys performed in this study. A total of 120 consumers and 40 street food vendors from four districts [Binh Thanh (BT), Thu Duc (TD), district 3 (D3) and district 8 (D8)] in HCMC contributed to the study on a voluntary basis. The surveyed consumers had adequate levels of food safety knowledge and attitudes. No significant difference (p > 0.05) occurred between the food safety knowledge levels of the consumers on the basis of gender. However, significant differences (p < 0.05) occurred on the basis of age, education level, food safety training status and location. In contrast, the street vendors had poor food safety knowledge and attitude levels. No significant differences (p > 0.05) were observed in the food safety knowledge levels of the vendors on the basis of gender and age. However, significant differences (p < 0.05) were found on the basis of food safety training status and education level. It was also noted that the vast majority (95%) of the vendors had not received any food safety training. With regards to the practices, it was determined that 52.5% of the vending sites were open air stands without any protection from the sun, wind and dust. 52.5% the vending stalls had no direct access to potable water, while 47.5% did not have adequate hand washing facilities and a further 30% lacked proper waste water and food disposal facilities. In addition, 52.5% of the vendors did not separate raw, partially cooked food and cooked food products. These findings highlighted that street food vendors in HCMC generally have poor food handling practices and most are operating under unhygienic conditions. These results should provide the Vietnamese government with even more reasons to increase their current efforts to improve the safety of street foods and food safety awareness of the consumers.     

茨林围的保育 澳门的圣保罗教堂,城中村与田园肌理

圣保罗学院仅存的教堂立面,是澳门最具历史意义的古迹。20世纪初涌入澳门的难民,沿着教堂后院城墙兴建住屋,形成茨林围这一片肌理丰富的违章社区,在高密度的城市中保持了独特的田园肌理。不同于主流话语中的宏伟教堂或广场,茨林围保存的是边缘社群的日常生活轨迹和一种活的建筑文化延续,是澳门旅游业在东西融合的主流话语背景下,不可缺少的庶民物质文化财富。规划所强调的循序渐进与人本尊重,更是在后殖民时代建立身份认同的澳门步入公民社会中不可缺少的进程。     

改进的“三图法”在煤矿顶板水害评价中的应用——以东胜煤田台格庙勘查区为例

通过建立台格庙勘查区首采煤层冒裂安全性分区图和煤层顶板含水层富水性分区图,来对煤层顶板的含水层涌(突)水条件进行评价。针对勘查区煤层厚度变化大、顶板无稳定隔水层,顶板含水层富水性较弱的特点,在传统的“三图法”基础上,充分考虑了含水层的富水性和导水裂缝带发育高度这两个因素,选用导水裂缝带高度与含水层厚度的百分比来表示导水裂缝带发育高度对含水层涌(突)水的影响,在此基础上对首采煤层顶板含水层涌(突)水条件进行综合分区评价。四井田中部及二井田北部地区涌(突)水危险性为较危险区,三井田北部、五井田南部及勘查区南部局部地区涌(突)水危险性为过渡区,其他地段为安全区、较安全区。针对顶板充水含水层涌(突)水条件综合分区,提出了疏放水、注浆、监测等防治水措施建议。
