Launched in 2009, Bitcoin is increasingly accepted and used more widely. With many advantages, Bitcoin has brought opportunities and challenges to the financial and noney market. Bitcoin has been accepted by many countries as a valid payment method such as Japan, South Korea, Singapore, Australia and so on. In Vietnam, Bitcoin has been introduced and has formed a community of users as well as developed the support platforms. However, Vietnam has not had the specific research and legal framework for this kind of currency to control it effectively. The paper analyzes the benefits as well as the risk of using Bitcoin. Furthermore, the paper emphasizes on effecting of Bitcoin on the financial and monetary market, socio economic and proposes some solutions to increase efficiency in Bitcoin management in Vietnam.

AbstractThe steel structure under the action of alternating load for a long time is prone to fatigue failure and affects the safety of the engineering structure. For steel structures in complex environments such as corrosive media and fires, the remaining fatigue life is more difficult to predict theoretically. To this end, the article carried out fatigue tests on Q420qD high-performance steel cross joints under three different working conditions, established a 95% survival rate $$S{ - }N$$ S - N curves, and analyzed the effects of corrosive media and high fire temperatures on its fatigue performance. And refer to the current specifications to evaluate its fatigue performance. The results show that the fatigue performance of the cross joint connection is reduced under the influence of corrosive medium, and the fatigue performance of the cross joint connection is improved under the high temperature of fire. When the number of cycles is more than 200,000 times, the design curves of EN code, GBJ code, and GB code can better predict the fatigue life of cross joints without treatment, only corrosion treatment, and corrosion and fire treatment, and all have sufficient safety reserve.

Background: Implant primary stability can be affected by several factors related to implant macrogeometry, local anatomy, and surgical techniques. The aim of this research was to study primary stability on polyurethane foam sheets of wide-threaded implant design compared to narrow-threaded implants. Materials and methods: Two different implant designs were positioned on D3 density polyurethane blocks in a standardized environment: the wide-threaded implant and the narrow-threaded implant, for a total of 160 specimens. Moreover, for each group, two different sizes were considered: 3.8mm × 12mm and 4.8mm × 12 mm. The insertion torque (IT) values, the removal strength (RT), and the Periotest analyses were evaluated. Results: A significantly higher IT and RT was reported for wide-threaded implants and two-stage implants (p < 0.01), compared to the narrow-threaded implants. The diameters seemed to provide a significant effect on the primary stability for both implants’ geometry (p < 0.01). A higher mean of the one-stage implant was evident in the Periotest measurements (p < 0.01). Conclusions: Both of the implants showed sufficient stability in polyurethane artificial simulation, while the wide-threaded implant design showed a higher primary stability on alveolar cancellous synthetic bone in vitro. Additionally, the prosthetic joint connection seemed to have a determinant effect on Periotest analysis, and the one-stage implants seemed to provide a high stability of the fixture when positioned in the osteotomy, which could be important for the immediate loading protocol.

We report greater than 10-year outcomes in duplicated thumbs following corrective cartilaginous resection during the growth period. We have undertaken corrective resection of cartilaginous joint connections based on intraoperative arthrographic findings to reconstruct favourable alignment in six Wassel Type II and IV thumb duplication in six patients. The age at surgery was 13 months (range 10–15), and the average post-surgical follow-up was 134 months (range 120–160). We observed five excellent and one good outcome using the Japanese Society for Surgery of the Hand scoring method. Favourable joint congruency and alignment were preserved, and no growth plate arrest or joint space narrowing was present more than 10 years after surgery. We conclude that corrective resection of the cartilaginous joint based on intraoperative arthrographic findings has long-term reliability for duplicated thumbs, especially those of Wassel Type II and IV, which have a cartilaginous joint connection.

Abstract Background Care integration has been an aim in government policies since 2000s in Finland. In 8 counties municipalities have created regional joint health and social care authorities in responsibility of all health and social services to boost service integration. Joint management gives possibilities to change organizational structures and organizing care paths in new ways. Most of these joint authorities suffer from severe budget constraints and layoffs has been done. Care integration has been seen as alleviating in budget constraints and to increase efficiency. In this study the views of top and middle managers and personnel on care integration as means to develop efficiency is explored. Methods A large, newly established joint authority of 200000 inhabitants participated the study. The joint authority had a large gap in its budget, hence layoffs were planned. We compiled a data of regional policy documents, carried out individual and group interviews of management (21) and a survey to employees (N = 2047). In the interviews, views of top and middle managers on how efficiency should be developed and on views of care integration in relation to efficiency were studied. The views of employees were explored in the survey. Results The joint authority was launched in a very short time and care paths were not planned before the organizational change. The managers saw that siloed practices created inefficiency and care integration increasing efficiency although the research evidence was seen insufficient. In the survey the views of the employees of developing efficiency and care quality were more negative than managers. Both groups, however saw that care integration was underdeveloped. Developing integration especially at primary level became also a key strategy of the joint authority. Conclusions Joint management creates a good basis for integration. The implementation of care integration, however, requires managers' collaboration and organisational culture supporting integration. Key messages In managers views care integration can increase efficiency. Joint management is a good basis for integration, but care processes have to be planned.
