The Spallation Neutron Source (SNS) project: a fertile ground for radiation protection and shielding challenges.

The Spallation Neutron Source facility presently under construction in the USA consists of a front end, a linac, an accumulator ring, a target station and a neutron instrument hall, producing pulsed neutron beams driven by a proton beam of 1 GeV energy and 1.4 MW power with a repetition rate of 60 Hz. The layout of the facility and the radiation protection and shielding concept of the facility is laid out in numerous examples in a walk from the proton beam generation to the neutron utilisation.

Target station shielding issues at the spallation neutron source.

Recent spallation neutron source shielding activities in support of the neutron beam shutters and the hot cell walls are presented. Existing neutron beam shutters can be replaced with concrete at low power or with concrete and steel at approximately 500 kW of beam power. Potential voids in the hot cell walls are analysed to determine the impact on dose rates as a function of void size. A change in the type of shielding work is noted as the project moved from the early design stages as a 'green field' site to the current stage as a construction project nearing completion, where issues to be addressed are approaching retrofit-type analyses.

[Individual style of communication with the outer world during long-term isolation].

Crew communication with ground controllers is a source of information for diagnostics of mood, mental performance and mutual understanding within space crew. The article analyzes results of dynamic observation of communication of small groups isolated from the outer world during project SFINCSS-99 performed at RF SSC-IBMP in 1999-2000 with the purpose to simulate life and interrelations within ISS crews. The project evidenced that some communication manners featured personal strategies of adaptation to the extreme conditions. A modified procedure of communication content-analysis proved to be a success in remote psychodiagnostics and to bear promise for analysis of crew personality and inter-relationship during space flight.

[Aspects of developing a unified information system of space crew medical support based on networking technologies].

Computerization of national and international space research projects, real-time data management, improvement of the quality of medical support to space crew through more extensive use of video, audio and telemetric information put in the forefront the necessity to integrate individual experts and agencies in a single network. Described is the structure of the operative network mounted at the Russian Federation State Research Center--Institute of Biomedical Problems. The authors discuss issues related to networking participants in medical support of manned missions, and a biomedical data exchange format. Developed was a prototype of an on-line Web-server. Prospect for advancement of the informational network is outlined.

[Modernization of methods amd technical means of information supply of piloted space flights].

The goal was to lay basis for a change to modern, adequate to international standards technology of the biomedical data transfer to and from the orbital complex, and setting-up a computer network to link all partners in the medical care systems for space missions. Main sources of the board biomedical information were identified as well as associated restrictions on communication capabilities and upgrading the in-flight procedures. Advantages of INTERNET were analyzed and the need for high-speed digital downlink of the biomedical data was substantiated.

[The oxidative phosphorylation system of BHK-21 cells in suspension cultivation].

The state of the oxidative phosphorylation system in intact and digitonin-treated BHK-21 cells in the lag-, logarithmic and stationary growth phases has been studied. It is shown that during the growth of cell culture the rates of oxygen uptake and the extent of coupling of oxidation and phosphorylation change significantly.

[Factors affecting the treatment results with pulmonary tuberculosis patients].

A study is presented of the effect of social factors on the outcomes of pulmonary tuberculosis in patients with freshly detected disease mainly in rural localities in 1985-1989. The outcomes of treatment depended mainly on the form and extension of the pathological process and terms of treatment. It was also established that the outcomes of tuberculosis are also influenced by unfavourable social factors which are more pronounced in persons with an extensive process. Treatment results were better in women with higher education than in similarly educator men. Among agricultural workers treatment efficacy was worse than among office workers and housewives. Life in the family effects more favourably treatment results than single life. Treatment results were worse in those living in unsatisfactory conditions, engaged in hard physical work, suffering of concomitant diseases and bad habits.

[The effect of social factors on tuberculosis morbidity].

The influence of social factors on tuberculosis morbidity in the Vinnitsa region was studied for the period of 1954-1965 (1365 examined subjects) and 1965-1989 (556 examined subjects). They included: income per family member, residence conditions, the nature of work and occupational hazards, education, bad habits, and marital status, etc.). Social factors have still influence on the possible development of pulmonary tuberculosis. A combination of unfavourable social factors (low income, hard physical labour, smoking, alcohol abuse, malnutrition, low hygienic level) as well as a separate factor (income per family member) have the greatest influence on tuberculosis morbidity. Recently, since provision with living space has been improved, this factor has a lower influence on the possible development of tuberculosis.

[Results of polychemotherapy in patients with newly detected destructive pulmonary tuberculosis].

The results of treatment of 224 patients with newly-diagnosed destructive pulmonary tuberculosis were analysed. These patients were divided into 4 groups in relation to the pathologic nature and chemotherapeutic regimen. The most effective results were produced in case of a simultaneous administration of 4 arrtituberculosis drugs irrespective of the pathologic nature. Under the above regimen, cessation of bacteria excretion and curing of cavities occurred in a shorter period of time, and for disseminated pulmonary tuberculosis, these processes were even more frequent than in the patients receiving 3 drugs. The tolerance to the treatment was quite satisfactory.

[Diagnostic errors in detecting open forms of pulmonary tuberculosis].

A study of 206 patients with open forms of pulmonary tuberculosis indicates that in 25.2% of them tuberculosis was initially diagnosed as pneumonia, bronchitis or tumour of the lungs. The main causes of diagnostic errors were inadequate knowledge of general practitioner of tuberculosis problems, neglect in examination of the sputum for MBT, incomplete scope and incorrect interpretation of roentgenological data.

[Communication within the mission control-space crew loop: the socio-psychological aspects].

The object of the article is a pilot study of audio communication between space crew and ground operators. The experiment was to validate a new method of content-analysis of radio contacts in order to evaluate the socio-psychological aspects of communication as within the crew, so between the crew and the Mission control center. The study supported the supposition of V.I. Myasnikov that the most frequent and active spokesman is a formal or informal crew lead. Also, each national MCC evidently prefers to contact its own crew member.
