Cultural and environmental values in the arcaded Mesaorian houses of Cyprus

The central Mesaorian region of Cyprus is the context for the development of a house form unique to the region. This article discusses the forces that influenced their evolution and the resulting typological developments. They are analyzed in terms of their functional characteristics, use patterns, and variations of the basic form. Thermal data suggests optimization of climatic forces. These adobe houses are currently facing oblivion due to changes in lifestyle and shift in priorities. They, however, present a case from which lessons can be learnt and adopted to the modern context for a meaningful and appropriate architecture in the region.     

西雅图心绞痛问卷对冠心病患者生活质量的评估

目的 采用西雅图心绞痛问卷(SAQ)对有心绞痛症状的冠心病患者生活质量进行评估,探讨影响患者生活质量的因素.方法 以2007年12月至2008年12月在北京协和医院心内科住院并进行冠状动脉造影,且在就诊前1个月自觉有心绞痛症状的513例患者为研究对象,根据Judkins评分分为轻度,中度和重度病变组,比较不同组患者生活质量的差异.以SAQ各项指标得分为因变量,以年龄、性别、心肌梗死、心绞痛、高血压、糖尿病、左心室射血分数等进行多因素逐步回归分析,找出影响冠心病患者生活质量的因素.结果 轻度、中度和重度病变组,活动受限程度评分分别为(80±16)分、(79±19)分和(71±22)分,差异有统计学意义(P＜0.01).对于生活质量SAQ的5个指标,活动受限程度的影响因素为年龄(P＜0.01)、性别(P＜0.01)和冠脉病变程度(P＜0.01);心绞痛稳定程度的影响因素为心肌梗死(P=0.03);心绞痛发生情况的影响因素为心肌梗死(P=0.01)、性别(P=0.04);治疗满意程度的影响因素为冠脉病变程度(P=0.03);疾病认知程度的影响因素为糖尿病(P=0.03).结论 年龄、性别、心肌梗死、糖尿病、冠脉病变程度等是影响冠心病患者生活质最的主要因素.     

宜人家园写意栖居——杭州金都华府住宅区设计体会

住宅区的品质不只体现在住宅楼形象和户型本身,居住区的环境设计日益成为衡量楼盘品质的最直接的条件。相比其他城市绿地,居住区的景观设计与人的日常生活联系更加紧密,而景观的细部处理往往是设计成败的关键,除了通常意义上的细节处理外,如何使住宅区更有自己的性格特质,是最能体现设计师用心与否的关键,而当地的文化传统往往是设计师的灵感源泉。充分挖掘历史,赋予其新的形式,从而使文脉得以延续,使历史文化更具生命力,金都华府项目以"人文住宅"为设计理念,在高密度的建筑群中继承传统,创造出符合现代城市人生活习惯的优质生活环境上,做了初步的尝试。     

Determinants of house dust endotoxin in three European countries - the AIRALLERG study

The comparison of endotoxin levels between study populations and countries is limited as a result of differences in sampling, extraction, and storage procedures. The objective of this study is to assess the levels and determinants of endotoxin in mattress and living room floor dust samples from three European countries, namely, Germany, the Netherlands, and Sweden, using a standardized sampling, storage, and analysis protocol. The mattress and living room floor dust was collected from the homes of 1065 German, Dutch, and Swedish (pre-)school children. All the samples were collected in the cool season and analyzed for endotoxin in a central laboratory. The determinants were assessed by a standardized questionnaire. The endotoxin concentrations in mattress and living room floor dust were found to be the highest in German homes and lowest in the Swedish ones. Differences between the geometric means were small (factor 1.1-1.7). Most of the associations between endotoxin concentrations and potential determinants were not statistically significant and heterogeneous across countries. However, keeping pets and having more than four persons living in the home were consistently associated with up to 1.7-fold higher endotoxin concentrations in mattress and floor dust. Furthermore, having carpets or rugs, and opening the windows frequently was associated with up to 3.4-fold and 1.3-fold higher endotoxin concentrations in living room floor dust, respectively. The proportion of variance explained by the questionnaire variables was generally low. In conclusion, the data on housing characteristics did not accurately predict the endotoxin concentrations in house dust, and could only partly explain the differences between countries. PRACTICAL IMPLICATIONS: The differences between the endotoxin concentrations in German, Dutch, and Swedish homes are small. House dust endotoxin concentrations are associated with a number of housing factors, such as pet-ownership, floor cover, number of persons living in the home, and ventilation. The variability of the endotoxin levels between homes and countries can only be partly explained by these factors.     

O2O背景下高校餐饮环境、大学生餐饮行为与个体BMI关系研究

“O2O外卖”作为信息时代的新兴产 物正在极大地改变着我国居民的餐饮方式 乃至生活习惯;其中,大学生是其重要受众。 本文以南京市为例,选取位于城市不同区位 的10所高校（校区）,基于传统问卷数据和 网络大数据,探究了O2O背景下高校餐饮环 境、大学生餐饮行为与个体超重的关系。研 究发现,高校周边的实体和虚拟餐饮环境具 有耦合性,但后者不健康食物的比例更高。 各类餐饮行为中,食堂就餐倾向主要受客观 建成环境的影响,而选择校外餐厅和外卖则 受可达性等客观因素与餐饮环境主观评价 的共同影响。改善实体餐饮环境能够降低大 学生选择外卖的倾向。研究在控制个体属性 与偏好的前提下未发现食用外卖与超重存在 统计相关性,但对点外卖人群而言,健康食 物的获取频率与个体BMI具有显著的负相关 关系。     

Impact of corneal collagen cross-linking on vision-related quality of life measured with the keratoconus outcomes research questionnaire (KORQ) in patients with keratoconus

PurposeTo assess the impact of corneal collagen cross-linking on self-reported vision-related quality of life (VR-QoL) in keratoconus patients by means of the Keratoconus Outcomes Research Questionnaire (KORQ), a new disease-specific patient reported outcomes measures (PROMs) tool.MethodsPatients with progressive keratoconus undergoing corneal collagen cross-linking were consecutively enrolled. Patients completed the KORQ before and after the treatment, at 1, 3 and 6 months. Data were collected regarding the visual acuity and the topographic, aberrometric and pachymetric parameters of both eyes. Patients were also asked to quantify their eye rubbing behavior on a Visual Analogue Scale (VAS) from 0 to 10, before and 6 months after treatment.The KORQ scores were associated with the visual acuity, topographic, aberrometric and pachymetric data by means of the Spearman correlation coefficient.ResultsThe Activity Limitation (AL) subscale score was higher after surgery. Preoperatively, negative correlations were observed between the KORQ AL score and Best Corrected Visual Acuity (logMAR), maximum keratometry, flattest keratometry, steepest keratometry, symmetry index front and higher order aberrations (HOA) of the treatment eye. Postoperatively, we observed a shift toward the fellow eye, with stronger correlation of the KORQ scores with the fellow eye parameters. The Symptoms subscale score correlated with the aberrometric parameters of both eyes at various time points. Statistically significant correlations were observed between the change in KORQ scores and the change in aberrometric parameters. A statistically significant reduction in the eye rubbing behavior was detected (p < 0,0001).ConclusionsThese results suggest that the corneal cross-linking treatment is effective both in improving the subjective perception of the disease by the patient and in stabilizing the objective indicators of disease progression. Keratometric, aberrometric and visual acuity values showed a significant impact on self-reported VR-QoL. Corneal cross-linking, by halting the worsening of these parameters, may bear a beneficial effect on VR-QoL.

贝叶斯方法在二维目标定位中的应用

本文对如何运用贝叶斯方法,以一维方式采集资料,进行二维目标定位作了一些探讨。实验中,运用光电计测定出发射和接收红外二极管的模式,通过分析建立起物体的二维模型方程,然后运用贝叶斯方法,估计出物体在坐标中的水平位置和垂直距离。进而验证了这种基于贝叶斯方法的二维物体定位算法。这为以后研制具有较强实用性的地雷探测仪或者是其它的不方便进入目标区域情况下的应用提供了方法上的依据。
