ObjectiveTo assess the reliability and usefulness of an EEG-based brain-computer interface (BCI) for patients with advanced amyotrophic lateral sclerosis (ALS) who used it independently at home for up to 18 months.MethodsOf 42 patients consented, 39 (93%) met the study criteria, and 37 (88%) were assessed for use of the Wadsworth BCI. Nine (21%) could not use the BCI. Of the other 28, 27 (men, age 28–79 years) (64%) had the BCI placed in their homes, and they and their caregivers were trained to use it. Use data were collected by Internet. Periodic visits evaluated BCI benefit and burden and quality of life.ResultsOver subsequent months, 12 (29% of the original 42) left the study because of death or rapid disease progression and 6 (14%) left because of decreased interest. Fourteen (33%) completed training and used the BCI independently, mainly for communication. Technical problems were rare. Patient and caregiver ratings indicated that BCI benefit exceeded burden. Quality of life remained stable. Of those not lost to the disease, half completed the study; all but 1 patient kept the BCI for further use.ConclusionThe Wadsworth BCI home system can function reliably and usefully when operated by patients in their homes. BCIs that support communication are at present most suitable for people who are severely disabled but are otherwise in stable health. Improvements in BCI convenience and performance, including some now underway, should increase the number of people who find them useful and the extent to which they are used.

Extrusion Forming

In this article, it mainly describes the use of extrusion production process as an example of the special shaft. It gives us a full analysis from the structure of the product, the material problems, the key technical problems needed to be solved, blank preparation processing and the process of extrusion forming. It also introduces the blank dimensions and the calculation method of the extrusion pressure. The method of blank lubrication processing and the process of designing extrusion mould.We are not unfamiliar with the center shaft of the bike. It is one of the important parts in bicycle bottom bracket. It is also a key part to determine the quality of the bicycle. Generally speaking, materials are used is 20 steel. The roughness of the surface is moderate. But the requirement of the product precision is high. We can get it by using mechanical processing method. But it is processing and the efficiency is low. While the utilization rate of mental material is low. So the production costs high. Because the parts production patch is large and the annual production is hundreds of thousands of pieces. In my opinion, it is more reasonable for us to adopt the technology of producing the parts with the cold extrusion precision molding process. Then we can save the materials, improve the efficiency of producing parts, lower the production parts and then meet the requirement of mass production.

The measuring of rendered services in any industry, especially in libraries, remains a critical tool to assess the satisfaction level of clients as well as the quality of the services. This article reports on a study that was undertaken to measure the quality of internet access service to South African public libraries by using the service quality model. The paper was guided by these objectives to identify the service quality models applicable to public libraries’ internet access; to determine how the quality of internet access service fits within the South African broadband policy; and to apply service quality dimensions to public libraries’ internet access. The study employed a quantitative approach and survey design in which a questionnaire was used to collect data from 322 heads of public libraries in South Africa. The stratified sampling method was used to obtain a proportional representation of public libraries. It emerged that most respondents regarded their internet service providers (ISPs) as incapable of solving their technical problems. It was further found that in most cases ISPs applied the internet access policies inconsistently to public libraries they served. The study recommended, among others, that internet connectivity to public libraries be centralised and that a competent provider be appointed to manage this service.

Social Nature

Physical activity is a basic factor of human development – it brings satisfaction, vitality, energy, has a therapeutic dimension and affects the quality of life. Among the large group of amateur athletes, there are people vulnerable to social exclusions related to disabilities, psychological dysfunctions, sex and social status. For these people sport is a cure for loneliness and lack of self-confidence, as well as it positively affects their motivation to overcome barriers, which is reflected in other spheres of their lives. One sport that in particular integrates different social groups is running, as confirmed by the growing number of amateur runners, training activities dedicated to them and running events organised for them. However, it is important that organisers of such events ensure the safety of participants and take care of their satisfaction and comfort by holistic planning of all organisational activities. The study hypothesised that factors concerning the safety, comfort and satisfaction of participants play a vital role in organising running events. The aim of the article was to identify and assess the risk of organising running competitions for amateurs in the context of ensuring safety and satisfaction for all participants of the event. In particular, the author noted the risk factors of a social nature, conducive to integration, associated with countering exclusions. The paper presents test results for national competitions involving 21 and 42 km runs. The identification of risk factors was performed by 10 experts (the Delphi method) and 27 representatives of 7 running events organised in Poland (2017–2018) (risk estimate, a questionnaire) took part in the risk estimation. Risk estimation was carried out on the basis of average (effect and probability). The results of the study provide unequivocal information about the spheres of organising sporting events which in the highest degree can affect the safety and comfort of their participants and the perception of the competition itself. Among the key risks there were: inadequate financial and organisational resources, route capacity, or technical problems. Moreover, the paper includes an attempt to discuss results of other research.

The Impact

The article is devoted to the study of coal mining industry problems in a region and environmental and economic damage caused by its activities. It is found that the intensive development of coal mining industry is accompanied by negative environmental consequences associated with the impact on social and economic indicators of a region and the quality of life of the population. The methodology for analysis and evaluation of environmental and economic damage to a regional economy based on the loss of gross regional product (GRP) and associated with the loss of working time due to the incidence of the population, determined by the level of environmental pollution, was developed. The developed methodology solves the problem of evaluating the impact of environmental components not only on environmental and economic damage, characterized by GRP losses, but also on the quality of life of the population. In addition, the optimization nature of the presented model allows finding the economic potential of producers and the objective efficiency of enterprises, which will make it possible to compensate for damage caused by environmental pollution that is adequate to the negative consequences of their activities.
