lndustrie Textile, Dec 1970, No. 996, 757-760; abstr, hz World Textile Abstracts Three recent publications, in which the work carried out by an operative attending to a ringframe has been carefully analysed, have been reexamined Where the results can be restated in the form of simple equations relating the number of spindles capable of being looked after by one operative to other spinning parameters, this has been done. 3.3"366(58607) Frafik6va, A. Some questions of raising labour productivity on assembly line work (In Czech) Synte'za, 1970, 111.4, 168-174 Psychological problems of assemblyline work and the influence of physical conditions upon workers' productivity are discussed. Organisation of work and economy of workers' energy together with workers' satisfaction with work and pay-motivation are also considered.

l'racovni Lekarstvi, 1969, 2 I. 6, 250-252; abstr, in Scientific Reports on Industrial Hygiene and Occupational Diseases in Czechoslorakia The author measured the caloric consumption in nine workers building an external wall and did not find that the physiologically recommended value for the whole working day was exceeded. On these grounds, the introduction of exceptional rest periods wre not recommended. 3.3.368(58611) Hanusova, V. Physiological basis for the determination of the rest-time at bricklaying works - second part: plastering (In Czech)
Pracovni Lekarstvi, 1969, 21.7, 305-31 O; abstr, in Scientific Reports on Industrial llygicne and Occupational Diseases in Czechoslovakia By studying the energy output after every minute of the working cycle during plastering, the author reached the conclusion, that, when the working norms are fulfillcd and the rest periods
observed, the energy output does not exceed the physiologically recommended value of I 500 kcal per shift. 3.3.369(58612) Hopkin, V.D. Work-rest cycles in air traffic control tasks
A bstr. in Scientific and Technical Aerospace Reports (Report No. N71-16915), Nov 1970 There is no established practice or international agreement on the total weekly hours worked in air traffic control tasks, or on the optimum lengths of watches or shifts. Tasks range from those with a high vigilance component, where efficiency is associated with short work periods and frequent brief rests, to those requiring long hand-over periods, where unacceptable double-manning would occur if the work periods were short. Continuous eight hour shifts, with meals at the working position, are not unknown; these shifts may include high workload; though not all the time. The air traffic controller has little influence on his own workload. Traditionally, his colleagues expect him to deal with whatever traffic enters his sector, lie does so, at the cost of hard and sustained effort when workload is high, which sometimes results in extreme tiredness which may prevent him from relaxing after the end of his shift. The effects of work-rest cycles on performance have been the subject of much discussion in air traffic control circles, but of relatively little scientific work. What has been done is reported, what could be done is suggested.
This paper is a further section of tile author's thesis on work study and worker remuneration, and provides several practical examples of the use of MTM in calculating wage rates, etc. Further research is continuing, with a view to the system being extended to company personne'l assessment. In this way, a uniform scale based on work study could be uscd to assess remuneration. The paper was presented at the Annual General Meeting of the MTM Association (UK) at Manchester in April 1970, and again at the Congress of the European Work Study Federation at Helsinki (June 1970).

itl Building Science Abstracts Describes a new development in work study management called MTM3 (methods-time-motion 3) to be used when rapid results are more important than absolute accuracy, ie for nonrepetitive work (short incidental elements where frequency of occurrence and proportion of total work cycle is low) and long cycle jobbing (work cycle of eight minutes upwards).
