This study investigated the association between self-reported and performance-based mobility and instrumental activities of daily living (IADL) in 854 women aged 62 years and older from ...population-based studies in Göteborg, Sweden. Self-reported mobility was assessed by asking the subjects if they experienced difficulties when walking outdoors, walking indoors and mounting stairs. Performance-based mobility was evaluated by a Postural-Locomotion-Manual (PLM) test, which objectively and precisely measured the subjects' mobility of lower and upper limbs and movement co-ordination using an optoelectronic technique. Independence/dependence in IADL was evaluated according to 4 activities, namely cleaning, shopping, transportation and cooking. IADL dependence associated with both self-reported difficulties in mobility and poor performance in the PLM test. A logistic regression analysis showed that self-reported mobility and the locomotion phase in the PLM test were two independent explanatory factors of IADL dependence. This study indicates that self-reported mobility and the PLM test can be used to evaluate the mobility components of daily life activities. The combination of these two methods improves the assessment of an individual's mobility, and defines a risk group of functional decline. Given the limitations of a cross-sectional design, further longitudinal studies are needed.

As applications are developed, functional tests ensure they continue to function as expected. Nowadays, functional testing is mostly done manually, with human testers verifying a system's ...functionality themselves, following hand-written instructions. While there exist tools supporting functional test automation, in practice they are hard to use, require programming skills, and do not provide good support for test maintenance. In this paper, we take an alternative approach: we semi-automatically convert hand-written instructions into automated tests. Our approach consists of two stages: first, employing machine learning and natural language processing to compute an intermediate representation from test steps; and second, interactively disambiguating that representation to create a fully automated test. These two stages comprise a complete system for converting hand-written functional tests into automated tests. We also present a quantitative study analyzing the effectiveness of our approach. Our results show that 70% of manual test steps can be automatically converted to automated test steps with no user intervention.
A two dimensional computational program was used to explore type, dimension, and number of windows in a 45 sqm domestic building to achieve cooling ventilation rates in 0 m/s outdoor windspeed. Prior ...to this, a manual calculation was constructed to limit and predict how the input for computational test would be. As in the manual test, the type of windows to be tested is jalousie (louvre) and casement. Primary and secondary weather data was also prepared for input. Subject to change variable is dimension and number of windows. Both manual and computational test indicated that to provide cooling ventilation rates (30 ach) in 0 m/s outdoor windspeed, the domestic building requires window area of approximately 50% floor area. Abstract in Bahasa Indonesia : Desain jendela bangunan domestik untuk mencapai "cooling ventilation" (30 air change per hour (ach) yang sangat dianjurkan bagi bangunan di daerah tropis lembab diuji pada studi ini. Pengujian dilakukan dengan sistem komputasi dua dimensi dan difokuskan pada kondisi kecepatan angin di seputar bangunan = 0m/det. Untuk memperkirakan model, dimensi dan jumlah jendela, sebelumnya telah dilakukan uji manual pada beberapa bangunan sejenis. Hasil uji manual yang telah dilengkapi dengan data-data primer dan sekunder mengenai suhu, kecepatan dan arah angin kemudian disusun sebagai input uji komputasi. Variabel yang senantiasa dirubah pada proses uji kali ini adalah dimensi dan jumlah jendela. Uji komputasi ini juga bertujuan untuk mem-validasi hasil uji manual tersebut. Kesimpulan yang dihasilkan tidak terlalu jauh berbeda dari kesimpulan pada uji manual, yaitu bahwa untuk memperoleh tingkat ventilasi cooling (30 ach) diperlukan luas jendela sekitar 50% luas lantai.
Lachman test is a manual test for examining the anterior cruciate ligament (ACL). An examiner examines the ACL by feeling finger stress. Some measurement device for Lachman test have been developed. ...However, they aim to analyze not the stress but a motion of the knee joint. Therefore, we set the goal of this study to develop a measurement system for finger stress with force sensor during Lachman test. In the experiment, one knee of a male without any injury was measured. In the results, the finger stress was observed by finger force sensor. As a result, we could detect the finger stress by the developed system.
Lachman test is one of manual tests for examining the anterior cruciate ligament (ACL). An examiner discreminates an injured degree of the ACL by feeling finger stress. Some measurement devices for ...Lachman test have been developed. However, these devices aim to analyze not the stress but a motion of the knee joint. Therefore, we set the goal of this study to develop a measurement system for the finger stress with force sensor during Lachman test. In the experiment, the developed system was applied to twelve healthy knees of six subjects by a beginner, and one injured and one healthy knee of two subjects by an expert. In the results, the maximum force of "endpoint" during Lachman test was analyzed. The variation of inter subjects was larger than intra-subjects. Future works are to improve the finger force sensors, and to apply more subjects, so that the system could classify an examiner into a skill level.
Reviews status of intellectual assessment. The AVOM Test is a potentially useful device. It measures performance in two input channels, auditory and visual, and two output channels, oral and manual. ...AVOM was administered to elementary school students. Scores increased with age, and other results support potential utility of the device. (Author)
