Opinion Polls

Two large-scale surveys looking at attitudes towards forests, forestry and forest policy in the second half ofthe nineties have been carried out. This work was done on behalf of the Swiss Confederation by the Chair of Forest Policy and Forest Economics of the Federal Institute of Technology (ETH) in Zurich. Not only did the two studies use very different methods, but the results also varied greatly as far as infrastructure and basic conditions were concerned. One of the main differences between the two studies was the fact that the first dealt only with mountainous areas, whereas the second was carried out on the whole Swiss population. The results of the studies reflect these differences:each produced its own specific findings. Where the same (or similar) questions were asked, the answers highlight not only how the attitudes of those questioned differ, but also views that they hold in common. Both surveys showed positive attitudes towards forests in general, as well as a deep-seated appreciation ofthe forest as a recreational area, and a positive approach to tending. Detailed results of the two surveys will be available in the near future.

At the present time, landscape inventories, the third National Forest Inventory (NFI), permanent research plots in the forests,cantonal inventories, regional forest planning, the redefinition of useful farm land, a new inventory of standard tree orchards but also the protection of peat bog and alluvial areas are daily business. Therefore, the development of a software for automated aerial photograph analysis is of greatest interest to the Swiss Confederation and its cantons as well as to forest owners, research institutes and certain industries (private engineering enterprises, software producers). In answer to these expectations, the Antenne Romande WSL, together with the Institute of Production in Microengineering of the Swiss Federal Institute of Technology Lausanne(EPFL), proposes to develop a software for user-friendly, neutral and rapid image-processing, the working precision of which will suit forest and landscape managers. Moreover, the software will provide scientists with basic data for the modelling of various ecosystem processes.

The object of research is the processes of data exchange between subjects of foreign economic activity when performing customs procedures, namely, the introduction of a new computerized transit system NCTS within the framework of improving and harmonizing customs procedures. One of the most problematic areas is the lack of knowledge and awareness in the implementation of reforms on trade facilitation measures, and therefore there is a need to be able to reduce costs at the border, and costs associated with foreign trade transactions. The perspective is considered and the assessment of the state of modern customs policy is carried out on the example of Ukraine, the mechanisms of application of customs instruments for regulating foreign trade during the digitalization of customs are determined. The dynamics of export-import operations of Ukraine with other countries is analyzed. In 2020, exporting companies estimate the work of customs significantly better by 15 % compared to 2019. Among enterprises of various sizes, micro-enterprises often report problems at customs, and the greatest problems are considered to be overstatement of customs value of goods and outdated equipment of customs control zones. It is shown that one of the ways to improve the efficiency of customs procedures is to minimize personal contacts between the customs officer and the client, transfer most of the transactions online, use electronic services and mobile applications. Also, in the near future, a large-scale reconstruction of checkpoints is planned to reduce queues. It is found that the customs clearance procedures are not sufficiently automated, and the customs authorities are entrusted with many obligations. Thus, the customs authorities of Ukraine are forced to control goods during customs clearance more carefully than in the EU countries. The average duration of customs clearance of imported goods by the customs authorities of Ukraine is from 1 to 4 hours, depending on the region, while in developed countries such clearance takes only a few minutes. The conducted research is interesting for the participants of the international transport market. Since for business enterprises the use of one transit declaration for the delivery of goods from one country to another (from the customs office of departure to the customs office of destination), according to the general transit procedure, reduces the cost of customs procedures and the time required for their passage. Consequently, it reduces queues at the border, which means a faster flow of goods.

Abstract. Background: Given that nursing staff play a critical role in the decision regarding use of physical restraints, research has examined nursing professionals’ attitudes toward this practice. Aim: Since nursing professionals’ views on physical restraint use have not yet been examined in Austria to date, we aimed to explore nursing professionals’ attitudes concerning use of physical restraints in nursing homes of Styria (Austria). Method: Data were collected from a convenience sample of nursing professionals (N = 355) within 19 Styrian nursing homes, based on a cross-sectional study design. Attitudes toward the practice of restraint use were assessed by means of the Maastricht Attitude Questionnaire in the German version. Results: The overall results showed rather positive attitudes toward the use of physical restraints, yet the findings regarding the sub-dimensions of the questionnaire were mixed. Although nursing professionals tended to deny “good reasons” for using physical restraints, they evaluated the consequences of physical restraint use rather positive and considered restraint use as an appropriate health care practice. Nursing professionals’ views regarding the consequences of using specific physical restraints further showed that belts were considered as the most restricting and discomforting devices. Conclusions: Overall, Austrian nursing professionals seemed to hold more positive attitudes toward the use of physical restraints than counterparts in other Western European countries. Future nationwide large-scale surveys will be needed to confirm our findings.

The Shuaiba Industrial Area (SIA) is located about 50 km south of Kuwait City. It accommodates most of the large-scale industries in Kuwait. The total area of the SIA (both eastern and western sectors) is about 22.98 million m2. Fifteen plants are located in the eastern sector and 23 in the western sector, including two petrochemical companies, three refineries, two power plants, a melamine company, an industrial gas corporation, a paper products company and, two steam electricity generating stations, in addition to several other industries. Therefore, only 30 percent of the land in the SIA's eastern sector and 70 percent of land in the SIA's western sector is available for future expansion. Presently, industries in the SIA generate approximately 204,000 t of solid waste. With future development in the industries in the SIA, the estimated quantities will reach 240,000 t. The Shuaiba Area Authority (SAA), a governmental regulatory body responsible for planning and development in the SIA, has recognized the problem of solid waste and has developed an industrial waste minimization program. This program would help to reduce the quantity of waste generated within the SIA and thereby reduce the cost of waste management. This paper presents a description of the waste minimization program and how it is to be implemented by major petroleum companies. The protocols employed in the waste minimization program are detailed.

Every day we are seeing an increasing number of robots being employed in our day-to-day lives. They are working in factories, cleaning our houses and may soon be chauffeuring us around in vehicles. The affordability of drones too has come down and now it is conceivable for most anyone to own a sophisticated unmanned aerial vehicle (UAV). While fun to fly, these devices also represent powerful new tools for several industries. Anytime an aerial view is needed for a planning, surveillance or surveying, for example, a UAV can be deployed. Further still, equipping these vehicles with an array of sensors, for climate research or mapping, increases their capability even more. This gives companies, governments or researchers a cheap and safe way to collect vast amounts of data and complete tasks in remote or dangerous areas that were once impossible to reach. One area UAVs are proving to be particularly useful is infrastructure inspection. In countries all over the world large scale infrastructure projects like dams and bridges are ageing and in need of upkeep. Identifying which ones and exactly where they are in need of patching is a huge undertaking. Not only can this work be dangerous, requiring trained inspectors to climb these megaprojects, it is incredibly time consuming and costly. Enter the UAVs. With a fleet of specially equipped UAVs and a small team piloting them and interpreting the data they bring back the speed and safety of this work increases exponentially. The promise of UAVs to overturn the infrastructure inspection process is enticing, but there remain several obstacles to overcome. One is achieving the fine level of control and positioning required to navigate the robots around 3D structures for inspection. One can imagine that piloting a small UAV underneath a huge highway bridge without missing a single small crack is quite difficult, especially when the operators are safely on the ground hundreds of meters away. To do this knowing exactly where the vehicle is in space becomes a critical variable. The job can be made even easier if a flight plan based on set waypoints can be pre-programmed and followed autonomously by the UAV. It is exactly this problem that Dr Kae Doki from the Department of Electrical Engineering at Aichi Institute of Technology, and collaborators are focused on solving.

Abstract Light fields with spatially varying backgrounds can modulate cosmic preheating, and imprint the nonlinear effects of preheating dynamics at tiny scales on large scale fluctuations. This provides us a unique probe into the preheating era which we dub the “cosmic microscope”. We identify a distinctive effect of preheating on scalar perturbations that turns the Gaussian primordial fluctuations of a light scalar field into square waves, like a diode. The effect manifests itself as local non-Gaussianity. We present a model, “modulated partial preheating”, where this nonlinear effect is consistent with current observations and can be reached by near future cosmic probes.
