This paper shows the estimation process of the hand’s anthropometric dimensions, for designing leather sewn gloves. Since there is not detailed information about hands in the anthropometric studies of the Colombian population, it was necessary here to use the ratio scaling method (RS) to estimate, 22 anthropometric dimensions. Subsequently, an anthropometric measurement was performed in a sample of 41 participants (18 female – 23 male), in order to compare the similarity between the measured and the estimated dimensions founding a correlation coefficient between 0.9396 and 0.9995, for male, and between 0.9587 and 0.9988, for female. It was found that the estimated dimensions have the required precision to use this information in the products design that involve a direct contact with human beings, which means that the measures can be obtained with a lower cost and in a faster way than with conventional anthropometric studies.

A method for ratio scaling of projective personality variables was devised and tested in two studies, using the TAT and achievement motivation (n Ach). In Exp. I, 4 judges made direct ratio estimates of relative n Ach in all possible pairs of 8 Ss' TAT protocols (28 pairs). In Exp. II, 3 judges used the same procedure to estimate relative n Ach for all pairs of TAT stories told to the same card, rather than for four-story protocols (112 pairs). Ratio scale values correlated with traditional n Ach scoring between .86 and .91 in Exp. I, and .90 and .95 in II. The protocols represented two criterion groups with different n Ach. Ratio scores from Exp. II, but not from I, differentiated these groups as well as traditional scoring. A model was developed for testing the internal consistency of judges' ratio estimates, based on Comrey's work. It showed over 90% of the ratio estimates' variance accounted for by the linearity assumptions of the ratio scaling model. Advantages and problems in using the ratio scaling method were discussed.

Anthropometry involves the external measurement of morphological traits of human beings. It has a widespread and important place in nutritional assessment, and while the literature on anthropometric measurement and its interpretation is enormous, the extent to which measurement error can influence both measurement and interpretation of nutritional status is little considered. In this article, different types of anthropometric measurement error are reviewed, ways of estimating measurement error are critically evaluated, guidelines for acceptable error presented, and ways in which measures of error can be used to improve the interpretation of anthropometric nutritional status discussed. Possible errors are of two sorts; those that are associated with: (1) repeated measures giving the same value (unreliability, imprecision, undependability); and (2) measurements departing from true values (inaccuracy, bias). Imprecision is due largely to observer error, and is the most commonly used measure of anthropometric measurement error. This can be estimated by carrying out repeated anthropometric measures on the same subjects and calculating one or more of the following: technical error of measurement (TEM); percentage TEM, coefficient of reliability (R), and intraclass correlation coefficient. The first three of these measures are mathematically interrelated. Targets for training in anthropometry are at present far from perfect, and further work is needed in developing appropriate protocols for nutritional anthropometry training. Acceptable levels of measurement error are difficult to ascertain because TEM is age dependent, and the value is also related to the anthropometric characteristics of the group or population under investigation. R > 0·95 should be sought where possible, and reference values of maximum acceptable TEM at set levels of R using published data from the combined National Health and Nutrition Examination Surveys I and II (Frisancho, 1990) are given. There is a clear hierarchy in the precision of different nutritional anthropometric measures, with weight and height being most precise. Waist and hip circumference show strong between-observer differences, and should, where possible, be carried out by one observer. Skinfolds can be associated with such large measurement error that interpretation is problematic. Ways are described in which measurement error can be used to assess the probability that differences in anthropometric measures across time within individuals are due to factors other than imprecision. Anthropometry is an important tool for nutritional assessment, and the techniques reported here should allow increased precision of measurement, and improved interpretation of anthropometric data.

Information regarding the cost of a construction project is available to the investor and project participants in order to determine the subsequent success of a project, given that the information they collect has an impact on the decisions they make. Cost calculations, especially in the initial phase of a project, often generate large errors. This paper presents the new approach based on a combination of the Case Based Reasoning method (CBR) with the originally selected criteria for the description of a construction project (as a result of Pearson correlation coefficient and Spearman's rank correlation coefficient) and Building Information Modeling (BIM) technology. The CBR method fulfils expectations for a simple and fast system supporting the cost estimation process. It does not require any specialist knowledge, so it will be comprehensible to cost estimation practitioners. The BIM-based model gives the opportunity for the calculation of quantity take-offs and enables the use of the information contained in the BIM model in the cost estimation process. In order to prepare the model an appropriate relational database had to be developed. With extensive research, a database of 173 construction projects, including the construction of a sports field, was obtained. There were 14 variables defined originally by authors; however, only 10 (as a result of the correlation analysis) were used for the calculation. Data related to the project were collected in the BIM model. Results estimating the project’s unit price, using the CBR method, were presented and discussed. The Mean Absolute Estimate Error was used to evaluate the model.

Maximum oxygen uptake (VO2max) is a “gold standard” in aerobic capacity assessment, playing a vital role in various fields. However, ratio scaling (VO2maxbw), the present method used to express relative VO2max, should be suspected due to its theoretical deficiencies. Therefore, the aim of the study was to revise the quantitative relationship between VO2max and body weight (bw). Dimensional analysis was utilized to deduce their theoretical relationship, while linear or nonlinear regression analysis based on four mathematical models (ratio scaling, linear function, simple allometric model and full allometric model) were utilized in statistics analysis to verify the theoretical relationship. Besides, to investigate the effect of ratio scaling on removing body weight, Pearson correlation coefficient was used to analyze the correlation between VO2maxbw and bw. All the relevant data were collected from published references. Dimensional analysis suggested VO2max be proportional to bw23. Statistics analysis displayed that four mathematical expressions were VO2max = 0.047bw (p<0.01, R2 = 0.68), VO2max = 0.036bw+0.71 (p<0.01, R2 = 0.76), VO2max = 0.10bw0.82 (p<0.01, R2 = 0.93) and VO2max = 0.23bw0.66–0.48 (p<0.01, R2 = 0.81) respectively. Pearson correlation coefficient showed a significant moderately negative relation between VO2maxbw and bw (r = -0.42, p<0.01), while there was no correlation between VO2maxbw0.82 and bw (r = 0.066, p = 0.41). Although statistics analysis did not fully verify the theoretical result, both dimensional and statistics analysis suggested ratio scaling distort the relationship and power function be more appropriate to describe the relationship. Additionally, we hypothesized that lean mass, rather than body weight, plays a more essential role in eliminating the gap between theoretical and experimental b values, and is more appropriate to standardize VO2max, future studies can focus more on it.

Electrostatic detection is remarkably developed and has been employed to detect human activity for years. In this paper, an induction electrostatic detector is designed, and used to measure human walking signals. The gait signals of totally six segments of the same object are measured in the experiment. An algorithm is proposed to obtain accurate gait cycle. The original signals are transformed to correlation coefficient series. Peaks of correlation coefficient series is picked out as the same phase point instead of peaks of walking signal. The time between very second peaks is defined as gait cycle of object. Based on the gait cycle, we discussed the recurrence property as the characteristics of human beings. It is expected that the slope of the recurrence line can be used as an index, and will indicate the personal particularity of objects in detection and their physical conditions.

Abstract The article, based on the Hindi short stories of S.R. Harnoṭ, focuses on the transformation of villages in an age of globalisation. The setting of the stories is the mountain villages of Himachal Pradesh, and, in a few instances, Shimla, also a mountain location. The article is divided into two sections. The first is an overview of the stories, the second covers two main themes: the arrogance of power and the distortions generated from its abuse, and the effects of glocalisation and the end of the social produced by technological progress, which cuts off direct contact between human beings. The two themes merge in a single discussion in the conclusion through the unifying element of nature, an ever-present theme that is at times explicit, at times implied. Throughout the analysis three terms have been used to highlight the changes in village life: modernisation, glocalisation and globalisation.

Akhlak (morals) is a very important part in human life, without which men will not reach the degree of a noble man. On contrary, human beings having good akhlak can distinguish between good and bad deeds to become a noble man. The issue of morality is currently experiencing acute decadence that must be quickly overcome by various circles. One of the ways is through learning the thinking of earlier muslims scholars. One of the earlier Islamic scholars is Syaikh Abdul Latief Syakur, one of the local ulamas in Minangkabau, whose academic background had a direct contact with the dynamics of Middle Eastern scholarship,and who contributed a lot of thoughts to uplift the dignity of the nation through morals. As a scholar, Syaikh Abdul Latief Syakur presented and describedseveral moral values to overcome the present moral decadence through his thoughts set forth in his work Tafsīr Surah al-Mukminūn. The application of moral values in this tafsir work contributes to the present moment by applying the values of the spirit of khusyu and khuḍhu’ which illustrates the humility and tepo seliro (tolerance) which are transcendent. Not only on its transcendent and cognitive aspects, but also on the other dimensions of humanity thoroughly and striving in winning nature (fitrah) and logics against lust.[Akhlak merupakan bagian yang sangat penting dalam kehidupan manusia. Tanpa akhlak manusia tidak akan memiliki derajat sebagai manusia mulia, sebaliknya manusia yang berakhlak dapat membedakan antara perbuatan baik dan buruk sehingga menjadi manusia mulia. Persoalan akhlak saat ini mengalami dekadensi akut yang harus cepat diatasi oleh berbagai kalangan. Salah satunya adalah melalui pemikiran ulama-ulama terdahulu. Salah satu ulama yang dimaksud adalah Syaikh Abdul Latief Syakur, salah seorang ulama lokal dari Minangkabau, dimana sisi akademisnya bersentuhan langsung dengan dinamika keilmuan Timur Tengah yang tidak sedikit memberikan warna pemikiran dalam mengangkat harkat martabat bangsa melalui akhlak. Sebagai seorang ulama, Syaikh Abdul Latief Syakur menghadirkan dan menguraikan nilai-nilai akhlak dalam mengatasi dekadensi akhlak masa kini melalui pemikiran yang dituangkan dalam tafsīr surat al- Mukminūn. Penerapan nilai-nilai akhlak dalam tafsir ini memberikan kontribusi kekinian dengan cara menerapkan nilai spirit-spirit khusyu dan khuḍhu’ yang menggambarkan kerendahan hati dan tepo seliro, dimana dari dua unsur tersebut bersifat transenden. Tidak saja yang transenden dan kognitif, tetapi lebih jauh pada dimensi kemanusiaan lainnya secara menyeluruh dan mengupayakan dalam memenangkan fitrah dan akal terhadap hawa nafsu.]
