AbstractThe Japanese National Large Telescope is an 8-metre class optical-infrared reflector with a monolithic thin meniscus mirror, to be constructed at the Mauna Kea summit, Hawaii. The JNLT will be characterised by high quality performance in the optical and infrared regions, achieved by adopting new technologies such as active mirror support, fast optics and a thermally controlled dome. In particular, high infrared qualities are regarded as the most important characteristics among various design goals.The JNLT project is now close to the final study phase before construction. This paper reviews the scientific motivations and the special technical features of the JNLT. Finally, the promotion of international collaboration around the JNLT is emphasised.

IntroductionMobile health (m-health) technology has been growing rapidly in the last decades. The use of this technology represents an advantage, especially for reaching patients who otherwise would have no access to healthcare. However, many ethical issues arise from the use of m-health. Health equity, privacy policies, adequate informed consent and a competent, safe and high quality healthcare need to be guaranteed; professional standards and quality of doctor-patient relationship in the digital setting should not be lower than those set for in-person practice.AimsTo assess advantages and threats that may arise from the wide use of m-health technologies, in order to guarantee the application of the best medical practices, resulting in the highest quality healthcare.MethodsA literature search has been conducted to highlight the most pressing ethical issues emerging from the spreading of m-health technologies.ResultsFew ethical guidelines on the appropriate use of m-health have been developed to help clinicians adopt a professional conduct within digital settings. They focus on the need for professional associations to define ethical guidelines and for physicians to take care of their education and online behavior when using m-health technologies.ConclusionsThe rapid spreading of m-health technologies urges us to evaluate all ethical issues related to its use. It would be advisable to produce an ethical code for the use of these new technologies, to guarantee health equity, privacy protection, high quality doctor-patient relationships and to ensure that m-health is not chosen over traditional care for merely economic purposes.Disclosure of interestSG received honoraria or Advisory board/consulting fees from the following companies: Lundbeck, Janssen Pharmaceuticals, Hoffman-La Roche, Angelini-Acraf, Otsuka, Pierre Fabre and Gedeon-Richter.

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

In this paper Enhanced Spider (ES) algorithm is proposed to solve reactive power Problem. Enthused by the spiders, a new Enhanced Spider (ES) algorithm is utilized to solve reactive power problem. The composition is primarily based on the foraging approach of social spiders, which make use of of the vibrations spread over the spider web to choose the position of prey. The simulation results demonstrate high-quality performance of Enhanced Spider (ES) algorithm in solving reactive power problem.  The projected Enhanced Spider (ES) algorithm has been tested in standard IEEE 57,118 bus systems and compared to other reported standard algorithms. Results show that Enhanced Spider (ES) algorithm is more efficient than other algorithms in reducing the real power loss.

Anodic spark deposition (ASD) is a novel technique to deposit bioceramic films on the surface of titanium (Ti) and its alloys, and the films prepared with nano/micro scale pores are characterized by high-quality performance for dental implant. Among the process parameters, electrolyte provides a leading role owing to its vital influence not only on the films chemistry but also on the electrical conductivity of the circuit, which affects the film properties. In this study, titania porous films were synthesized by ASD and the effect of electrolytic temperature on microstructure and chemical composition of the films was studied. The results show that the electrolytic temperature could significantly influence the surface topography, thickness and chemical composition of the oxidation films produced by ASD and, therefore, determined the layered hydroapatite (HA) deposition as the other process parameters were fixed.

AbstractThe very large development of home and domestic electronic appliances as well as portable device has led the microelectronics industry to evolve in two complimentary directions : “More Moore” with the continuous race towards extremely small dimensions hence the development of SoCs (System on Chip) and more recently a new direction that we could name “More than Moore” with the integration of devices that were laying outside the chips and here the creation of SiPs (System in Package).These two approaches are not in competition one with the other: the paper will show some examples of integrated nano systems that use several SoCs.The technology we have developed is called Silicon Based System in Package. The first products using this technology are now in volume production and used mainly in the field of wireless communications.This new technology relies on four pillars. Passive integration is the first. Very efficient and high quality factor capacitors and inductors have been integrated, allowing the creation of complete modules including active devices, filters and decoupling capacitors. High-density MOS capacitors with 1-1000 nF capacitance, and as high values as 25-250+ nF/mm2 specific capacitance have been fabricated in macroporous Si-wafers, containing over 1 billion macropores. Typically an ESR less than 100 mÙ and an ESL less than 25 pH were found for capacitors over 10 nF. This novel concept is an important step forward in improving the stability of power-amplifier modules by replacing conventional SMD technology.Whereas generations with capacitors density of up to 100 nF/mm2 will be using “conventional” materials and structures, the next steps in the roadmap will call for new 3D structures and materials such as high-k dielectrics.The second element is advanced packaging. New technologies, such as the assembly of Silicon chips onto other Silicon chips, also named “double flip chip” have been developed. This has been made possible thanks to the combination of the most advanced microbumping and die placement techniques. In addition to a tremendous reduction of size (up to a factor of 10 to 20) these techniques have also brought a better repeatability of system performance.The third element has been the development of design tools that allow a seamless system design for engineers used to IC design tools and flows. Our Design Environment allows co design of multiple technologies chips and their integration in a single system. This IC-like Design Environment has contributed a lot to the adoption of the technology.Testing is the fourth element and is one of the economical enablers of the technology. The key words are: “known good die”, RF test, system test? Some innovative RF probing and full on wafer subsystem test will be shown. Even though efficient test is not vital for the technical feasibility of this system integration, it becomes very quickly one of the most important enablers, especially when we deal with very high volumes of production. The conclusion of the paper will be an open door to the future. Some innovations like the integration of light or even energy storage inside our SiPs will be presented.

The importance of professional competence lies in the effective application of job-oriented knowledge and skills which guarantee one’s successful adaptation to the work. This study analyzes the perception of the importance of physical activity and sports (PAS) professionals’ competence in working with individuals with disabilities in Spain. As a descriptive quantitative study, face-to-face interviews were conducted through a survey to extract the data. The sample consisted of 214 PAS professionals working with people with disabilities. According to the results, the analyzed constituents of professional competence are important for adequate performance (&gt;65%), with the exception of competences of leadership and use of new technologies (&lt;50%). It was also found that the perceived importance of each element of professional competence varies according to age, experience and training. Based on the obtained results, the degree of importance of each constituent of professional competence and its implication for the access of people with disabilities to high-quality physical activity and sports services was determined.

This paper examines the involvement of sixteen undergraduate students across four disciplines in a practice-led research project to create the “Once Upon a Time in Palestine” XR documentary by exploring how they performed when given complex challenges, to create this novel and complex practice-led research project. The students were trained and mentored but also were trusted to work under minimal supervision. This created a high level of engagement with the expectation of high-quality output and presented the students with opportunities not afforded to them within the rigid structure of their academic programs. This paper examines the engagement of the students, and their willingness to learn new technologies and apply this learning to produce high quality output under tight deadlines with minimal supervision and the value of interdisciplinary collaboration across multiple fields of study. The paper concludes that while there was a steep learning curve, the students were able to achieve high-level engagement and produce professional results within the specified deadlines, using the latest technological advances in the field, while learning new skills outside their academic program and also enhancing the outcome of the successful project.
