“…Some comment on the skin colour data seems justified in view of remarks that Ethiopians tend to be comparatively light coloured by African standards (Coon 1965). In actual fact, the levels of reflectance measured with the spectrophotometer are very low and at the shorter wavelengths the Ethiopian values are not distinguishable from Negro groups such as Yoruba and Ibo (Barnicot 1958). At longer wavelengths, where among dark-skinned peoples there is greater discrimination with the EEL spectrophotometer, the Ethiopians present higher values than these Nigerians and also Okavango Bantu, but they are darker than Khoisan populations, and darker even than Negroes living in Europe (Weiner, Harrison, Singer, Harris & Jopp 1964).…”

A study has been made of three neighbouring populations living at 1500, 3000 and 3700 m in the northern Simien of Ethiopia. The environments of these populations not only differ in many climatic elements, but also probably in nutritional factors and exposure to infections. The growth and physique of the people vary with altitude and the lowlanders (at 1500 m) tend to have a more linear body build. Differences in chest dimensions can be related to functional differences in respiratory physiology, since the highland groups, both male and female, have larger forced expiratory volumes and forced vital capacities as compared with the lowlanders. The relationships between these measures of respiratory function and age, stature and weight also tend to be dependent on altitude, but in all the Ethiopian groups there is a closer relationship between body weight and respiratory capacity than in other populations. This distinctiveness is probably due to the characteristics of Ethiopian physique. A slight polycythaemia and elevated packed cell volume are evident in the highland groups but, unexpectedly, there is some evidence that at least at the time of the expedition the haemoglobin concentrations were lower. The highlanders also show a raised systolic blood pressure. Blood-group and demographic data suggest that the various populations are probably genetically very similar, and the findings are discussed in terms of physiological and developmental adaptability.

This topic surveys the basic procedure of data base system of the fabric structural design which can be linked with existing pattern design and garment design CAD systems. For this purpose, the theoretical and empirical equations related to the fabric structural design are analyzed and discussed. The fabric structural parameters such as weave density coefficient, cover factor and yarn density coefficient of various kinds of fabrics are calculated using the empirical equations. These calculated fabric structural parameters of many kinds of polyester, nylon, worsted and cotton fabrics are compared and discussed with weave pattern, weaving loom and materials according to weaving manufacturer. Furthermore the difference between fabric structural parameters calculated by empirical equations are analyzed with polyester, nylon, worsted and cotton fabrics, and these structural parameters are analyzed and discussed with weave and finishing shrinkages. Finally, the case study of the data base system for fabric structural design is presented with weave pattern, weaving loom and weaving manufacturer, and also presented with the application fields to the existing woven fabric and clothing CAD systems.
