[The spread of the backspray under different working conditions].

The use of high- and highest-speed preparation instruments and the therefore required intensive spray cooling results not only in more efficient working possibilities but also in an increased infection hazard, especially for the dentist and his assistance caused by the spray rebound. Simulated preparations were carried out on different tooth surfaces at different positions of the patient with or without exhaust under clinical conditions to objectify the space spreading of the spray rebound. The arrangement of the equipment has been objectified by photogrammetry so that the measurement data could be clearly classified. The use of the spraying mist exhaust reduces the spray rebound between 50 and 65%.

Women in construction: occupational health and working conditions.

Construction is one of the largest industries in the United States, employing 7.6 million workers, or about 5% of the US work force. More women have taken jobs in the construction industry over the last two decades, as they have in other nontraditional industries. In 1997, there were 8.1 million construction workers, of whom 781,000 (9%) were women. Approximately 2% of those were employed as skilled tradeswomen. There is no disputing that construction work is dangerous. Seventeen percent of all fatal on-the-job injuries occur in construction, which is about three times its 6% share of total employment. In this paper, we review the medical literature on the safety and health hazards for women working in the construction industry. Women have a different pattern of fatal injuries and some differences in patterns of nonfatal injuries than men and report unique problems and concerns related to working in this industry.

[Comparative evaluation of microbial colonization of newborns according to the working conditions of maternity houses].

This study was aimed on the investigation of microbial colonization of 57 newborns at maternity home, applying the working program "BFH" ("Friendly attitude to child" -- a system of joint requirement of mother and child with respect to introducing the method of early delivery to breast-feed), and microbial colonization in 45 newborns and their mothers at ordinary maternity home, where they were being held apart from each other. The final results of the investigation showed up the following: the microbial colonization of newborns at the departments, applying the "BFH" program as working system, presented to be more than 2 times less intensive, compared to the newborns, held apart from their mothers. The gram-positive microflora (epidermal staphylococci, in 30% of cases they demonstrate the hemolytic features) and the culture of C. albicans were manifested to be prevalent in the microbial structure of newborns. The outcomes of the investigation give the base for recommendations for full engagement of maternity homes in the working system based on the principle of "mother-child" and family-oriented obstetrics.

A study of work conditions on board fishing vessels in the far-eastern region.

The authors present the results of investigations conducted on board sea-going fishing vessels during long-lasting voyage. They covered common dangerous occupational exposures to noise vibration, lighting, microclimate, air pollution in the work zone and the ship construction. The negative conditions these concerning were described.

Computer programs for calibrating control electrode voltages and for conditioning working electrodes for a neurochemical voltammetry system.

Two computer programs are described which are used to set voltages, calibrate the system, and cyclically condition electrodes electrically in an electrochemical system. This voltammetry system is normally used for measurement of monoamines in neurochemical studies. The system uses an Apple II, a potentiostat, and a DAS-5 interface between the two. The calibration program is used to establish the numerical values needed by the DAS-5 interface from the computer to yield desired potentiostat voltages, to calibrate the potentiostat, and to set output voltages of the system to be safe for the electrode and neural tissue before the potentiostat is turned on. Another program is used to condition electrodes as required in some cases to establish discriminably different oxidation potentials for different electroactive compounds (monoamines and ascorbate).

[Hygienic characteristics and ways of improving working conditions at a rug-making factory].

A complex of occupational factors, such as noise, vibration, workplace air dust loading, toxic fumes, forced work posture, neuroemotional and visual stress, affected health of those engaged at the carpet-making factory. The workers of basic professions experienced fatigue that was accumulated to the end of the working week. Diseases of the osteomuscular system, hypertension, vegetovascular dystonia, skin and subcutaneous fat infections, inflammatory diseases of female genital organs, hearing deterioration became more frequent in proportion to workers' age and length of service.

Achilles tendon: US diagnosis of pathologic conditions. Work in progress.

Twenty-three patients were prospectively examined with ultrasound (US) for acute or recurrent Achilles tendon symptoms. Three types of pathologic conditions of the Achilles tendon were found: tendinitis/tenosynovitis, acute tendon trauma, and postoperative changes. US appears to enable differentiation of these conditions and to contribute to the diagnosis of a broad range of Achilles tendon disorders.

Free markets and the marriage market: structural adjustment, gender relations, and working conditions among Dominican women workers.

The relationship between economic conditions and marriage patterns in the Dominican Republic is analyzed using data collected in 1994 on women working in a free-trade zone. The author concludes that changes associated with structural adjustment appear to have contributed to a deterioration of the job market and a greater prevalence of female-headed households. It is shown that "structural adjustment increases the need for women to work, because of cuts in government programs, declining real wages, growing inflation, and a deterioration in male employment, which weakens the man's role as principal breadwinner and increases the importance and visibility of women's contribution to the household economy. This change in the gender composition of the labor force has encouraged some women to resist marriage and/or remarriage because the ¿marriage market' of eligible men willing and able to support a family has been reduced, contributing to greater marital instability."
