Medical technology advances from space research

Details of medical research and development programs, particularly an integrated medical laboratory, as derived from space technology are given. The program covers digital biotelemetry systems, automatic visual field mapping equipment, sponge electrode caps for clinical electroencephalograms, and advanced respiratory analysis equipment. The possibility of using the medical laboratory in ground based remote areas and regional health care facilities, as well as long duration space missions is discussed

New Zealand regions, 1986 – 2001: Hospitalisation and some related health facts

Once age and gender composition is controlled for, regional health differentials are a function of problems of health service delivery, of socio-economic variance, and overall Māori Pakeha health differences. They indicate relative levels of exclusion and of inequality. This paper shows that these differentials follow in general the patterns seen in other papers in this series

Environmental effects of shuttle launch and landing medical information management, and management, planning, and implementation of the medical program are also dicussed

GaP betavoltaic cells as a power source

Maximum power output for the GaP cells of this study was found to be on the order of 1 microW. This resulted from exposure to 200 and 40 KeV electrons at a flux of 2 x 10(exp 9) electrons/sq cm/s, equivalent to a 54 mCurie source. The efficiencies of the cells ranged from 5 to 9 percent for 200 and 40 KeV electrons respectively. The lower efficiency at higher energy is due to a substantial fraction of energy deposition in the substrate, further than a diffusion length from the depletion region of the cell. Radiation damage was clearly observed in GaP after exposure to 200 KeV electrons at a fluence of 2 x 10(exp 12) electrons/sq cm. No discernable damage was observed after exposure to 40 KeV electrons at the same fluence. Analysis indicates that a GaP betavoltaic system would not be practical if limited to low energy beta sources. The power available would be too low even in the ideal case. By utilizing high activity beta sources, such as Sr-90/Y-90, it may be possible to achieve performance that could be suitable for some space power applications. However, to utilize such a source the problem of radiation damage in the beta cell material must be overcome

Deposition of diamond-like films by ECR microwave plasma

Hard amorphous hydrogenated carbon, diamond-like films are deposited using an electron cyclotron resonance microwave plasma with a separate radio frequency power bias applied to a substrate stage. The electron cyclotron resonance microwave plasma yields low deposition pressure and creates ion species otherwise unavailable. A magnetic mirror configuration extracts special ion species from a plasma chamber. Different levels of the radio frequency power bias accelerate the ion species of the ECR plasma impinging on a substrate to form different diamond-like films. During the deposition process, a sample stage is maintained at an ambient temperature of less than 100.degree. C. No external heating is applied to the sample stage. The deposition process enables diamond-like films to be deposited on heat-sensitive substrates

Mobility, sexual networks and exchange among bodabodamen in southwest Uganda

In order to examine the sexual behaviour of a highly mobile social-group, qualitative data and quantitative data were elicited from 212 private motorbike taxi-men, locally called bodabodemen, from two study sites in Masaka, Uganda. Selection criteria were availability and willingness to participate ill the study. Research techniques employed were a questionnaire, focus group discussions, in-depth interviews and case studies. Findings indicate that bodabodamen are a highly mobile group who engage in frequent seasonal rural-urban migration. Consequent to this, bodabodamen have a wide network of both occasional and regular sexual partnerships. Both serial and concurrent multiple partnerships are with adults, youths, widows, students, sugar-mummies, barmaids, commercial sex workers, tailors. Exchange plays a significant role in sexual negotiations but the act of giving to a sexual partner is ambivalent in its social interpretation. Since bodabodamen have regular access to cash, they have higher bargaining power for sex. Implications for HIV/ AIDS prevention are discussed

Shuttle OFT medical report: Summary of medical results from STS-1, STS-2, STS-3, and STS-4

The medical operations for the orbital test flights which includes a review of the health of the crews before, during, and immediately after the four shuttle orbital flights are reported. Health evaluation, health stabilization program, medical training, medical "kit" carried in flight, tests and countermeasures for space motion sickness, cardiovascular, biochemistry and endocrinology results, hematology and immunology analyses, medical microbiology, food and nutrition, potable water, Shuttle toxicology, radiological health, and cabin acoustical noise are reviewed. Information on environmental effects of Shuttle launch and landing, medical information management, and management, planning, and implementation of the medical program are included

Attitudes to voluntary counselling and testing for HIV among pregnant women in rural south-west Uganda.

UNLABELLED: This paper describes the results of a study exploring the attitudes of women attending maternity clinics to voluntary counselling and testing during pregnancy in rural areas in south-west Uganda. It was a qualitative study using focus group discussions (FGDs). Twenty-four FGDs were carried out with 208 women attending maternity clinics in three sites in rural south-west Uganda. The FGDs were all recorded and transcribed, and analysed using standard computer-based qualitative techniques. Almost all women were willing in principle to take an HIV test in the event of pregnancy, and to reveal their HIV status to maternity staff. They were anxious, however, about confidentiality, and there was a widespread fear that maternity staff might refuse to assist them when the time came to deliver if their status were known. This applied more to traditional birth attendants than to biomedical health staff. There were also rumours about medical staff intentionally killing HIV-positive patients in order to stem the spread of the epidemic. Women were concerned that if their husbands found out they were HIV-positive they would be blamed and separation or domestic violence might result. IN CONCLUSION: although VCT during pregnancy is acceptable in principle, much will need to be done to ensure confidentiality and allay women's fears of stigmatisation and discrimination during delivery. Community sensitisation will be necessary and male partners will have to be involved if interventions are to be acceptable
