Background:Telemedicine counseling (TMC) has gained rapid development during the COVID-19 pandemic. The prospect of using this technology in rheumatology was based on the possibility of getting maximum information about the patient during the survey, examination and interpretation of laboratory and instrumental data, that is excepting direct contact with the patient. Several rheumatological clinics have reported on the success of using TMC. However, there is very little data of the difficulties that can be encountered when organizing this process.Objectives:To characterize the identified problems during TMC in rheumatology, to suggest potential directions for their elimination.Methods:Since June 2021, on the basis of the Medical Association “New Hospital”, Yekaterinburg, Russian Federation, 76 TMCs have been performed on the profile of rheumatology in patients aged 29 to 71 years. Of these, 13 applied to the primary TMC, the other patients were preliminarily examined in person. The consultation included the preliminary acquaintance with the examination results, a 20-minute video communication and writing of a conclusion. After each TMC, a survey was conducted between the doctor and the patient, including the identified deficiencies in counseling. The frequency of identified problems is presented as an absolute indicator and as a percentage of the total number of TMCs performed.Results:We noted a high degree of patient satisfaction: 74 (97.4%) responded that they received answers to all. However, according to the doctor, the following groups of problems were identified.[1]Technical problems in 29 (38.2%): most often there were various problems with the Internet, but there were also registered: the end of the charge on the patient’s tablet, the patient was not registered in the electronic queue. Elimination of these violations depends on the work of IT-specialists, but each consulting physician should be prepared for an immediate transition to an alternative form of communication (for example - telephone).[2]Lack of objective examination, leading to the impossibility of correct remote diagnosis - 8 (10.5%). This problem was identified due to the inability to establish the presence or absence of arthritis during the initial diagnosis (6 cases) and to clarify the nature of the rash (2 cases). All patients are invited for a face-to-face consultation.[3]The need to write prescriptions for psychotropic drugs - 12 (15.8%), which under the conditions of national legislation cannot be done in the TMC regime.[4]The time spent directly on remote communication with the patient was 17.2 minutes (from 8 to 31), however, taking into account the study data and writing the conclusion, the total time was 40.7 minutes (from 21 to 73). Thus, it turned out that the average time for remote and face-to-face consultations is the same, while TMC’s payment is only about 50% of the face-to-face consultation. This situation reduces the doctor’s interest in carrying out TMC. The solution to the problem is associated with reducing the time for the documentation process through technical improvements. In addition, of the 9 patients in whom the TMC process lasted 60 minutes or more, 5 were diagnosed with fibromyalgia. It is possible that with a previously established diagnosis of fibromyalgia, only face-to-face counseling should be recommended to patients.Conclusion:The TMC system is promising, however, there are a number of problems that need to be improved, since they can reduce the doctor’s interest in using this technology.Disclosure of Interests:None declared

In the past few decades we have been improving our understanding of the weather system and exploring ways to modify it. Over sixty countries have experimented with modifying the weather. The new technology of weather and climate modification will raise important political problems which will demand new responses from the international community. Whether states will be able to establish the cooperative measures necessary to develop and manage new technology depends upon whether there are sufficient incentives to do so. This article analyzes the historical patterns of international cooperation in meteorology, and then plots against several time horizons projected developments and capabilities in weather modification technology and the potential problems emerging from using the technology. It derives a tentative picture of the responsibilities demanded, compares the likely responses with those needed, and assesses whether they will be adequate for the problems projected.

This study aims to analyse the implementation of new rice field plan  policies in Indonesia and their impacts on population and ethnic composition in new rice field locations. This research is conducted by applying a literature review method. It is shown that the implementation of the policies had two major implications. Firstly, it creates assimilation opportunities through collaboration between ethnic migrants and local ethnic groups to work on or cultivate new rice fields. Secondly, the great flows of transmigrants that move to the new rice field locations trigger ethnic polarization, which is prone to cause inter-ethnic conflict. In the future, potential problems associated with the provision of new rice fields are available are the risk of having aging population. The aging population indicates a decrease in productive labor that may also affect on decreasing attractiveness of the rice fields to the younger generation. This situation can lead to the re-involvement of older generation in managing the new rice fields. However, it can raise a new concern on their ability to improve the rice fields’ productivity or, even worse, the new rice fields might be neglected or be sold.

Science and technology incubator, as an organization dedicated to serving science and technology enterprises, has many functions, such as cultivating small and medium-sized science and technology enterprises, transforming science and technology into productivity, adjusting regional and national industrial structure, promoting the development of high and new technology industries, and promoting employment. Since the emergence of the first business incubator in the United States in the 1950s, this new form of social and economic organization has been developing rapidly all over the world, and has cultivated a large number of successful enterprises, which initially made great contributions to promoting the development of the world economy. However, with the increasing number of science and technology incubators and the rapid development of science and technology enterprises, various problems in the management system and operation mode of science and technology incubators are gradually exposed, which seriously affects the sustainable development of science and technology incubators in China. In view of this, based on the analysis of the current situation of science and technology incubator management in China, this paper puts forward the construction strategy of standardized management system of science and technology incubator in order to promote the scientific development of science and technology incubator in China.

The landmasses of the coastal areas of Bangladesh still remains under-utilized, thus cropping intensity is much less than the national average. Most areas remain fallow during dry (rabi) season from December to May due to presence of higher concentration of salts in soil and water, and scarcity of suitable irrigation water. Available adaptation options or technologies are not capable to solve these problems at all. Nevertheless, the areas receive a lot of water from monsoon rain, most of that rainwater is drain-out as surface runoff. The present study results suggest that the use of harvested rainwater and conservation agriculture either in combination or alone could mitigate the problem for bringing huge areas under crop cultivation. The public social safety net programmes such as cash-for-work, food-for-work etc. can be deployed for excavating or re-excavating the abandoned coastal ponds, ditches or canals for storing rainwater. Salt-, drought- and/or heat-tolerant crop varieties with short life span can also be cultivated to get the better results. Early plantation or growing crops with early-maturing varieties can ensure safer harvest in ahead of stress arrives. The avenues have immense potential as climate-smart practices for growing crops preferably non-rice crops during dry season in vast fallow land that will not only ensure food security for coastal people but could turn the entire southern Bangladesh as a food surplus zone. The findings refer the broad recommendation, therefore, specific research works based on the locations and resources available are necessary.


Assimilation of relevant information within a labour observatory is a key to success of an observatory. Management of such relevant information and its dissemination to the right audience at the right time is also important. In this regard, a labour observatory plays a very important role for successful operationalization of agricultural policies within developing countries. Historical information regarding soil, crop varieties, agricultural practices, and skill of agricultural labourers needs to be maintained by a labour observatory. Information from the observatory has to be communicated to policy makers for making a pragmatic decision in developing countries with large agriculturally dependent populations. These decisions can impact the lives of this population and can impact the sustainable development of these countries. Initiatives related to labour observatory started more than a decade back in developed countries. It has now begun in parts of Africa, too. The chapter highlights these developments and contextualizes the association between these observatories, agricultural policymaking, and sustainable development.

Effects of microorganisms on building facades are responsible for aesthetic, bio-geophysical and biogeochemical deterioration. The process of cleaning of contaminated facades involves the removal and eradication of micro flora on the surface of insulation using chemical products, killing cells and eliminating all living mass, including organic ingredients. The removal of bio corrosion coating from ETICS structure by means of chemical and preservative substances (biocides) is currently the only effective and most used technology. Uncontrolled leaching of the used biocides is unacceptable. Meantime, new technology for environmentally safe maintenance of ETICS is needed. Scientists have been working on replacement the biocides currently used in facades treatment with eco-friendly biocides that have no negative effects on the environment or human beings. While the eco- treatment will be available, safe dewatering of chemicals being leached from the surface of the facade could be provided by e.g. special drain systems adjusted to the building type, use and age. The paper gives an overview of the problem in context of Slovakia and examples of leaching systems designed for new and renovated buildings.
