measurement

This paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. The purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. We have employed a multi-method approach which combines a “qualitative” and “quantitative” analysis. Three squares were chosen as a setting for either a video observations, climatic measurement and interviews with the users. The whole investigations were conducted one day in winter 2009 and one day in summer 2010. The result of the qualitative and the quantitative analysis revealed that the climate variables played very different roles in predicting the use mode and density of the three squares in the two seasonal periods.

Purpose: Muscle flexibility is a component of physical fitness. Using traditional tools in muscle length evaluation tests creates challenges. Therefore, the use of smartphones and health-related software as an alternative method has become widespread. This study aimed to investigate smartphones' intra- and inter-rater reliability and validity for measuring hamstring muscle length. Method: In a blinded study design, two researchers measured hamstring flexibility through four types of tests on each of the 22 asymptomatic participants with a total of 44 lower limbs. The measurements were compared between the traditional goniometer method and the practical smartphone application method. The intraclass correlation coefficient (ICC) was used to evaluate the reliability of each smartphone measurement, and Bland-Altman analysis was used to check the measurement errors. The validity of the two methods was also investigated. Results: Intra- and inter-rater reliability (ICC≥0.8) were good to almost perfect. In intra-rater reliability, PSLR angle showed consistent imprecision; other tests were free of systematic error and measurement error. The inter-rater reliability revealed a constant error in the right leg's PKE angle. A good to excellent correlation (r = 0.817–0.699) was observed in all the measured values, indicating the two methods' validity. Conclusion: These findings support from intra- and inter-rater reliability and validity of both instruments when measuring hamstring muscle length.
