Cancer Center Staff Satisfaction: Descriptive Results of a Canadian Study.

Caring for cancer patients is generally considered very rewarding work, but it can also be stressful and demanding. Therefore, it is important for oncology healthcare professionals to feel satisfied with their work environment in order to provide the best care possible. An ethics-approved 61-item staff satisfaction survey was developed in-house to gain insights regarding workplace satisfaction among all staff at The Ottawa Hospital Cancer Center. Descriptive statistics were used to analyze the responses. A total of 478 individuals completed the online survey, with 75.1% women, 23.2% men, and 1.7% preferring not to say. This represented the vast majority (>75%) of cancer center staff. The approximate breakdown according to healthcare professional type was as follows: 21% nurses, 20% radiation therapists, 18% physicians, 13% clerical staff, and 28% other types of staff. Almost all (97.4%) generally enjoyed their work, with 60% stating "very much" and 37.4% stating "a little bit", and 93.3% found working with cancer patients rewarding. The overall satisfaction level at work was high, with 30.1% reporting "very satisfied" and 54.2% "somewhat satisfied". However, in terms of their work being stressful, 18.6% stated it was "very much" and 62.1% "a little bit". Also, in terms of their workload, 61.3% stated it was "very busy" and 10% stated it was "excessively busy". The most enjoyable aspects of work were listed as interactions with colleagues, interactions with patients, and learning new things. The least enjoyable aspects of work were excessive workload, a perceived unsupportive work environment, and technology problems. Levels of satisfaction and stress at work varied according to role at the cancer center. Most cancer center staff seem to enjoy their work and find it rewarding. However, the work environment can be challenging and stressful. Areas for improvement include managing workloads, ensuring staff feel supported, and improving the user-friendliness of technology.

Features of hydrodynamic calculation of highly loaded plain bearings of heavy ship’s gears

Despite the high level of modern vessel engineering development, there are a number of unresolved design and technological problems, the most urgent of which is the issue of unification of the main components and assemblies of the vessel. At the same time, an important and unresolved task is to create a unified image of the ship’s reverse gear for the needs of the domestic civilian fleet and navy. The object of study is highly loaded bimetallic plain bearings, which are elements of the “heavy” marine reverse gears of a new generation. As part of the work, a hydrodynamic calculation that refines the parameters of the plain bearings of a highly loaded marine transmission at the stage of a prototype production is performed. The applicability of the State Standard ISO 7902 methodology to the products under consideration is assessed, as well as the approximation of the performance characteristics of bearings using interpolation of two variables function is performed. The rationale for the coverage angle and the location of the pockets for supplying lubrication of bearings taking into account the thermal and viscous properties of the oil is presented. Calculations of the parameters of the critical thickness of the lubricating layer, the maximum allowable specific load and the maximum allowable temperature of bearings are performed. Based on the results of the calculations, an additional assessment for the compliance of bearings with the requirements of State Standard ISO 7902 in terms of bearing capacity and stability parameters is carried out. The comparison of the obtained results with the data of the preliminary calculation performed at the stage of the technical project is given. It is revealed that when calculating dynamically loaded plain bearings, it is necessary to take into account a number of additional factors, namely the magnitude of the relative eccentricity and relative clearance. The risks of bearings failure in the process of dynamic loading are determined. The result of the work is the correction of the geometric parameters of the plain bearings of the marine reverse gear unit in order to increase its reliability and the overhaul interval.

Поиск технологических возможностей на основе анализа патентного массива

Currently companies still rely heavily on expert knowledge when searching for technological opportunities and choosing partners. Automation of search of patent holders who can be partners of the enterprises of the Volgograd region is considered. Companies not only from Russia, but also from China, India, and other friendly countries are considered as partners. The process of identifying partners is based on the similarity of solved technological problems extracted from patent documents, the patent holders of which are these enterprises. By analyzing the dependency trees extracted from the patent fields “Scope of the invention” and “Name of the invention” the “Problem-Solution” structures are formed. Based on the analysis of patent documents of potential partners “Problems-Solutions” that are not patented in Russia are identified. It causes a “technological vacuum” for enterprises of the Russian Federation. A method for identifying technological capabilities based on the analysis of the world patent array has been developed. The novelty of the method which provides a search for potential innovative technological areas for key enterprises of the Volgograd region lies in the use of deep learning technologies in relation to the analysis of natural language data of the world patent array. A software module has been developed to search for technological opportunities for enterprises of the Volgograd region based on the similarity of technological problems. The module is programmatically implemented in Python, the Yargy library from the Natasha project was used for semantic analysis of text fields of patents, Deep–translator was used for translating patent documents into Russian, Stanza library was used for building dependency trees, and RuWordNet library was used for selecting hyperonyms (to account for synonymous words). In order to identify technological opportunities for enterprises of the Volgograd region, 6 785 patents were analyzed.

COMPARISON OF THE EFFECT OF DIFFERENT DIRECT EMULSION EMULSIFIERS ON SYSTEM STABILITY

The use of classical systems on both water and hydrocarbon bases is limited by a number of factors and technological features of such solutions. Hydrocarbon-based drilling muds are non-ecological, have a strong dependence of rheological parameters on temperature, and have a high cost. At the same time, water-based fluids do not have sufficient inhibitory and lubricating properties and increase the risk of problems during well construction. For environmental and economic applications, there is also a type of drilling fluid represented by an oilin- water emulsion of the first type (m/v). Such systems have high technological efficiency compared to abnormally low reservoir pressures, and environmental and economic advantages compared to hydrocarbonbased solution. The initial use of such systems was determined by their use under waterbased solution conditions in order to reduce reservoir repression during drilling. However, such systems also have good hydrophobizing and inhibiting properties, low water loss to the formation and greater environmental friendliness compared to hydrocarbon-based solutions. Such characteristics allow to consider the system refinement to solve the current technological problems in the field of well construction. Experience in the development and use of similar systems is reflected in the works, based on the results of laboratory and field tests, a formulation of a stable emulsion of the 1st type is presented, which includes an aqueous phase saturated with chloride. To determine the possibility of using the systems, pilot tests are carried out for the stability of the system based on various emulsifiers

Enhancing the Value of Coffee Husks as Organic Fertilizer in Windu Sari Farming Group, Batukaang Village, Kintamani Bangli

Coffee Husks produced from coffee processing are waste that can be used as raw material for making organic fertilizer. Utilizing coffee Husks as organic fertilizer can increase added value and farmers' income while reducing the smell from piles of coffee Husk waste, which can pollute the environment. Development efforts to overcome this problem include processing coffee Husk waste into compost. In this service activity, partners will be introduced to and trained in the technology for making quality compost fertilizer and managing coffee farming businesses to provide added value and improve the farmer's economy. This service aims to increase the added value (value added) of coffee Husk waste as organic fertilizer in the Windu Sari Farming Group. The problems found in farmer groups are the problem of piles of coffee husk waste, which have not been appropriately handled, and the problem of technology for making compost fertilizer, which has not been fully understood by partners, as well as farming business management problems related to group strengthening. The method used in community service in Batukaang Village is the Participatory Action and Learning System (PALS). This method aims to make the partner group an object in service activities through various forms such as education, training, counseling, as well as coaching and mentoring. The PALS method is implemented in several stages: (1) awareness phase, (2) capacity building phase, mentoring phase, and (3) institutionalization phase. The results obtained from this service program are in the form of a technology package for making compost fertilizer. From the service that has been carried out in the form of counseling, training, and the practice of making organic fertilizer compost, the response from the community, in this case, the Windu Sari Farmers Group, has been excellent.

Optical monitoring of adsorption of chromium (VI) molecular anions, molecules and clusters on carbon nanomaterials

Search for efficient adsorbent materials for removal of hexavalent chromium compounds from environment is a topical technological problem. In this paper, the possibility of optical monitoring of the adsorption of chromium (VI) molecular compounds on the surface of carbon nanomaterials (CNM) is examined. Theoretical calculations of optical absorption spectra of CrO42- anions and molecular clusters of such anions with metals, n*K2CrO4 (n = 1, 2, 4) and MIICrO4 (MII = Zn, Cd, Pb) adsorbed on the surfaces of bare and doped carbon nanotubes and graphene are carried out by TD-DFT method. Results of calculations are compared with experimental data on optical transmission, diffuse reflection and photoluminescence of specially prepared samples containing chromate molecular compounds and particles adsorbed on CNM.It is shown that adsorption of CrO42- anions by CNM can be detected by the appearance of characteristic bands in diffuse reflectance spectra in 310–380 nm region. Nanoparticles of K2CrO4 crystal adsorbed on CNM reveal an additional luminescence band in 600–700 nm region, and it can be utilized in the monitoring of such adsorption. The effect of CNM surface on optical spectra of chromium (VI) molecular compounds is analyzed in terms of splitting of excited electronic states of quasi-tetrahedral CrO42- anions.

An integrated framework for agricultural non-point source pollution control technology evaluation: Application of an improved multiple attribute decision making method

An Intuitionistic Fuzzy - Combined Weight - Mahalanobis distance - Multiple Attribute Decision Making (IFCM-MADM) method is proposed to solve comprehensive evaluation problem of the pollution control technologies for non-point sources in planting industry. The method is able to achieve cooperative improvement of the traditional TOPSIS on quantitative transformation of qualitative data in the evaluation indices by integrated intuitionistic fuzzy theory, subjective–objective combination weight calculation for the evaluation indicators by coupling the AHP and entropy weighting method, and accurately calculation on the distance between the evaluation object and the positive/negative solution by introducing the Mahalanobis distance to avoid the impact of correlation between indicators. Then, 34 typical technologies for agricultural non-point source pollution control selected from Major Science and Technology Program for Water Pollution Control and Treatment (MSTPWPCT) in China are employed for case application and validation, and the evaluation result obtained by IFCM- MADM has been deeply analyzed by comparing with the recommendation technologies provided by MSTPWPCT and the other two evaluation methods. The result shows that, the IFCM- MADM method can provide a scientific evaluation and selection of the technologies with high comprehensive benefits (including economic benefits, environmental benefits, and technical performance), which is highly consistent with the recommendation result from MSTPWPCT, and is capable to weaken the disadvantage of the objective weighting method and subjective weighting method, to a certain extent. The proposal of IFCM-MADM is the first attempt to enhance the traditional TOPSIS by extending its abilities on quantitative data processing, index weight calculation and accurate calculation of relative closeness, concurrently, and the method is also appropriate to other practical environmental evaluation problems with high complexity and multiple attributes.

Long-term control of non-point source pollution by adjusting human environmental behavior in watershed-a new perspective.

The control of non-point source pollution is a major scientific and technological problem faced by mankind. We proposed a new approach to eliminate non-point source pollution, focusing on adjusting human environmental behavior. The implementation procedures are as follows: (1) Investigate the intention of pollution discharge behavior through interviews and questionnaires. (2) Carry out targeted intervention within the framework of social psychology to transform it into an environmentally friendly mode. (3) Calculate the amounts of pollutants produced and discharged before and after the intervention, and then evaluate the effect of the intervention on reducing pollution. (4) Based on successful interventions, a scheme can be developed to curb non-point source pollution. Aiming to reduce fertilizer use, a case study was conducted in Hetao Irrigation District, one of the three major Irrigation districts in China. The results showed that the interventions indirectly affected intention through attitude, subjective norm, and perceived behavioral control. The structural equation model explained 76.0% of the total variance of farmers' intention to reduce fertilizer application (SMC = 0.760), indicating effective intervention. Subsequently, a program to curb non-point source pollution was developed. This study can provide a key scientific and applied reference for the long-term control of non-point source pollution in watershed.

Artificial Intelligence Governance and China’s Experience under the Community of Common Destiny for Mankind Concept

In recent years artificial intelligence (AI), backed by big data and the Internet, hasbeen rapidly developing and determining the future direction of the world’s scienceand technology development. Although artificial intelligence is beneficial to the scientific and technological revolution and industrial modernization of mankind, it hasalso brought new risks. People pay more and more attention to the potential risks ofartificial intelligence that should be effectively managed. Artificial intelligence risksare characterized by the diversity of technological threats, the similarity of AI risksfaced by different countries and the high complexity of governance, something thatrequires concerted efforts by all countries. It is necessary to carry out the development of artificial intelligence in the country from the perspective of the commoninterests of mankind, ensure the safety and manageability of artificial intelligence,and strengthen international cooperation. At present Western countries advocatethe concept of technological hegemony and technological monopoly, and developing countries have little opportunity to express their opinions on the governance ofartificial intelligence, and China’s Community of the Common Destiny for MankindConcept is necessary for the governance of artificial intelligence. Based on that concept, the paper explores China’s new practices and proposals for the domestic andinternational AI governance. In response to the problem of overuse and misuse ofnew technologies, China proposes to establish an artificial intelligence governancesystem that includes joint management by various actors, open and transparent regulation, comprehensive consultations, and the development of effective evidence-based laws, so as to promote the beneficial development of artificial intelligence inthe future and contribute to the deepening of AI governance based on the Chineseproposal.

EVALUATION OF THE EFFICIENCY OF ELECTRIC LOGGING METHODS WHEN STUDYING TIGHTNESS OF CASING STRINGS IN WELLS OF URANIUM DEPOSITS

Link for citation: Sharapatov A., Assirbek N., Samanbetov N. Evaluation of the efficiency of electric logging methods when studying tightness of casing strings in wells of uranium deposits. Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 10, рр. 7-15. In Rus. The relevance. When exploiting uranium deposits using the method of in-situ leaching, many problematic issues arise. Among them, it is possible to distinguish a violation of the integrity and tightness of the polymer casing, which leads to leakage of solutions due to defects and threaded connections, colmatation, etc. With the help of geophysical wells surveys, namely current logging and resistivity logging, there is a technological possibility of obtaining actual data on the leakage of solutions into the near-wellbore space (their location, size). The distribution of solutions in the annulus lead to technological and environmental violations during the development of deposits. The main aim: comparative evaluation of the effectiveness of current logging and resistivity logging in solving technological problems – assessment of the integrity of polymer pipes and tightness of threaded connections in the casing of uranium wells and determination of the parameters of liquidation of wells with damaged columns based on the data of current logging or resistivity logging in the casing. Objects: artificial defects in the casing for experimental work: holes in pipes with different diameters and locations, leaky connections of casing pipes. Methods. The work was carried out at one of the sites of the Shu-Sarysu province uranium deposit and includes the following activities: preparation of polymer casing strings for the experiment; physical and technical justification of using geophysical wells surveys methods to study the problem; performing measurement work by current logging and resistivity logging methods; performing computational work using current logging, resistivity logging readings and obtaining values of a probabilistic parameter for evaluation of the state of the casing strings and the decision on the operation of wells; comparative analysis and drawing conclusions on the informativeness of borehole geophysical (electrical) methods. Results. Research results showed that to solve the problem of monitoring the technical condition of casing strings, the use of the resistivity logging method is optimal. The conclusions of the research are based on the analysis of the nature of changes in the diagrams of the electrical methods of current logging and resistivity logging, the sensitivity of the measured values of the electric field to defects in the casing. The quantitative values of the parameter % ANO – the amount of current leakage (anomalies) obtained by calculation according to current logging and resistivity logging data are probabilistic in nature. They made it possible to develop recommendations for making technological and/or managerial decisions on the condition of casing strings and the further use of production wells with various defects in them.

Проблемы человеческого капитала и новых технологий — ресурсов, определяющих развитие современной экономики

To identify the reasons for the limited economic growth in modern Russia, the problems of resources that ensure economic growth are analyzed. These resources are the human capital of skilled and highly skilled workers and new technologies. The problem of human capital lies in the fact that the main trend in Russia in the second decade of the 21st century was the crushing of the growth rate of human capital in the form of a decrease in the level and loss of premiums for education of all types and levels. The problem of new technologies is the low level of exports of high-tech goods, which is less than 3% of the world volume, which corresponds to the 30th place in the world. Problems in the field of education and science, firstly, are due to the fact that management is based on a command-and-control style, in which management is based on the application of orders, norms, standards, the provisions of which are full of paradoxes and errors. and application of control, organized, among other things, on the basis of mass reporting. Secondly, the problems are due to the fact that the costs of education in modern Russia are small, amounting to 4–5% of GDP, therefore the country ranks 120th in the world in terms of the indicator, and the cost of research and development in the country is about 1% of GDP, which corresponds to 37th place in the world in this indicator. The number of highly qualified personnel in the field of education and science is shrinking. Problem solving can be achieved by increasing the cost of education and science, reorganizing the management systems of education and science, which does not ensure the coordination of activities and the use of resources necessary to achieve the goals of education and science. The regulatory and legal framework should be revised, organizational and managerial structures should be rebuilt, and the number of managerial personnel should be radically reduced.

(Re)Designing Security and War? Reflections on Transgressive Creativity and International Relations

Abstract In the discipline of IR, a growing number of academics work with artists, designers, architects, and filmmakers to explore a range of global political, economic, and security challenges. At the same time, there has been a concern—made powerfully by Dan Öberg—that there is a danger of what he terms “transgressive creativity” in the way that new approaches and methods are being used to respond to security challenges, especially in a military context. In this essay, I explore how the problem of this “transgressive creativity” is a concern shared by two groups working on the problems of security, war, technology, economy, and politics: critical designers and military designers (or the group that is becoming known as the Archipelago of Design). While the objectives of both communities are different, they both share a view that a sense of openness to collaboration is essential to go beyond traditional institutional approaches in order to make sense of complex and uncertain futures in a time of technological acceleration and geopolitical change. The essay concludes that we should be vigilant to the problems of transgressive creativity that Öberg alerts us to, but we also need to broaden the research agenda to understand how creative techniques are being used by a variety of actors and organizations to address the problems of international politics; academics in IR also need to see whether the “openness” to collaboration has broader disciplinary and methodological implications for researchers.
