Hybrid Emerging and Destructive Technologies with Implications on National and European Security and Sovereignty

Abstract Although they are part of the common lexical background of all languages, the notions of technique and technology are very difficult to define or separate exactly. However, science and technology are considered as two parallel flows of knowledge that have interdependencies and mutual relations; they support each other in the processes of creation and innovation. From other perspectives, technology is defined as the practical application of knowledge, especially in a particular field; a way of performing a task, in particular using technical processes, methods or technical knowledge; a system of specialized aspects of a particular field of activity (e.g. communication technology, educational technology, medical technology, competitive technology, etc.). Management consulting firm Arthur D. Little (USA) proposed a classification of technologies into four classes, depending on the competitive impact, as follows: core technologies, key technologies, emerging technologies and embryonic technologies. Hybrid destructive emerging technologies is a phrase that suggests a range of new technologies, some with some continuity, with hybrid use, but whose applicability is mainly aimed at destructuring organizational and state systems and subsystems, in order to make them dysfunctional and enslaved. The phrase also suggests the knowledge and means necessary for the application of emerging technologies, as a systematized set of knowledge about human activities, which make use of scientific research results, experiments, calculations and projects, as well as appropriate tools for conducting research. Technological knowledge is built using scientific methods with wide applicability, but focused in the direction of dissolving, destructuring, blocking, threatening and subjugating the will of organizations considered hostile. Emerging destructive actions on the European Union are materialized, among other aspects, by the increasingly obvious manifestations in the European democratic climate, such as: ignoring and circumventing the constitutive acts, the lack of unanimity on migration issues, cultivating media uncertainty about the future of the European Union, intensifying steps specific toopen societies and the proselytism of civic forums. These are, in our view, not only forms of democratic slippage, but also directions of hybrid destructuring, both at Community and national level, as certain hybrid destructuring issues stem from anti-democratic slippages at Community level which canbe seen more clearly at national level.

Event related delta and theta oscillations are reduced in severe obstructive sleep apnea as a possible electrophysiologial evidence of subtle cognitive changes

AbstractBackgroundObstructive Sleep Apnea Syndrome (OSAS) is a common sleep disorder that leads to widespread cognitive impairment when left untreated. OSAS is also reported as a risk factor for developing Alzheimer’s disease. Recent studies report a shared pathophysiology between OSAS and Alzheimer’s disease (Polsek et al., 2018; Baril et al., 2018). Working memory and attention related ERP P300 deficits were previously reported (for a review see, Raggi and Ferri, 2012). This study aims to investigate electrophysiological changes by using time‐frequency analysis to gain a better understanding on cognitive impairment in OSAS.Method56 severe OSAS patients and age, education and gender matched 33 healthy controls were participated to the study. Participants completed a classical auditory oddball task. A complex Morlet with Gabor normalization was applied and total power within four frequency bandwidths, delta (0.5‐3.5 Hz), theta (4‐7 Hz), alpha (8‐13 Hz), and beta (15‐30 Hz), was calculated using Event‐Related Spectral Perturbation (ERSP) analyses.ResultOSAS patients had reduced delta and theta ERPS to target stimuli compared to healthy controls in repeated measures ANOVA yielding a significant main GROUP effect (respectively, [F(1,87)=9.181, p=0.003] and [F(1,87)=5.083, p=0.027]). No differences were found on alpha and beta power.ConclusionWe found reduced delta and theta activity in severe OSAS patients. Delta EROs activity is associated with attention and decision making (Başar ve Stampfer, 1985; Stampfer ve Başar, 1985), whereas theta activity was associated with task induced activation of working memory (Yordanova et al. 2000). Reduced delta and theta EROs activity can be useful indices of subtle cognitive impairment in severe OSAS even before neuropsychological test. These results strengthen our understanding of the cognitive changes in OSAS by means of electrophysiological methodologies. This study was supported by Dokuz Eylul University Scientific Research Projects (Project Number: 2014.KB.SAG.058).

A call for observations of birds with sublingual oral fistulas in central and eastern Europe, and beyond

Abstract Birds with major physical abnormalities do not live for extended periods and, therefore, are rarely observed in the wild. This is particularly the case for birds with defects in their feeding apparatus that succumb to mortality rapidly through precipitous declines in their foraging efficiency and body condition. Sublingual oral fistulas are such an abnormality and involve the development of an opening (or fistula) in the floor of the oral cavity through which the tongue extends, resulting in its permanent exclusion from the mouth. The tongue dehydrates and dies. First described in the 2000s in Stitchbirds (Notiomystis cincta) in New Zealand, it has rarely been reported in other species. However, following our recent discovery of two seabird species on Ascension Island in the South Atlantic displaying oral fistulas, in 2016 I launched a citizen science research project requesting reports of birds with the condition in the world’s avifauna. To date, I have received 188 reports of birds of 82 different species with many contributed from western Europe. However, with only one report from central and eastern Europe, I am now requesting the assistance of birders in the region and in other parts of the world to contribute to this ongoing research project.

Science and Technology ODA Promotion of Korea through ICT of Global Problem Solving Centers -Suggestion on the mid- and short-term projects promotion of science and technology ODA roadmap-

The Korean government proposed the K-SDGs in 2019 to promote the UN SDGs, but the role and tasks of science and technology, an important means of implementing the SDGs, have not been materialized. Accordingly, the role of science and technology ODA for the SDGs was established through the Ministry of Science and ICT's policy research project 'Science and Technology ODA Promotion Roadmap for Spreading the New Southern Policy and Realizing the 2030 SDGs'. In addition, goals, strategies, and core tasks for the next 10 years were derived in 10 fields such as water, climate change, energy, and ICT. In this paper, we analyze 30 key tasks of the ODA promotion roadmap for science and technology for the realization of SDGs, and propose mid- and short-term tasks and implementation plans for effective roadmap promotion. Among the key tasks in each field, four common elements were derived: ICT/smartization, a global problem-solving center, cooperation/communication platform, and business model/startup support platform/living lab that can create and integrate roadmap implementation conditions. In addition, the four mid- and short-term tasks, 1) Establishment of science and technology ODA network, 2) Establishment of living lab business platform linked to start-up support business, 3) Local smartization of recipient countries, and 4) Expand and secure sustainability of global problem-solving centers, were set in relation to the implementation of the detailed roadmap. For the derived mid- and short-term tasks, detailed implementation plans based on the ICTization of global problem-solving centers were presented. The implementation of the mid- and short-term tasks presented in this paper can contribute to the more effective achievement of the science and technology ODA roadmap, and it is expected that Korea's implementation of SDGs will also achieve high performance.

Kirkpatrick's evaluation of the effect of a nursing innovation team training for clinical nurses.

This study aims to design a 100-h training programme for nursing innovation teams and to evaluate the effect of this training programme using Kirkpatrick's model. The innovative capability of nurses is a powerful driver for the development of the nursing discipline, and it is currently at a low to medium level in China. Innovation competency development has become a research trend in nurses' in-service education, but only changes in nursing innovation behaviours before and after training have been evaluated. The cascading, continuous assessment tools are rarely used. This is a quasi-experimental research design: pretest and posttest design. Totally, 61 clinical nurses from Hangzhou Hospital of Traditional Chinese Medicine were enrolled for innovation training. This innovation team training programme consisted of a 36-h theoretical training phase and a 64-h collaborative training phase. The four levels of Kirkpatrick's model, that is, reaction, learning, behaviour, and result, were applied for the evaluation together with questionnaires. At reaction level, the nurses' attendance was over 85% in two phases. The differences between nurse organizational innovation climate scores of tested nurses before and after training were statistically significant (t = -22.559, P < .001). At learning level, there were statistically significant differences between nurses' innovation self-efficacy scale scores of tested nurses before and after training (t = -16.832, P < .001). At behaviour level, the nursing innovation behaviour scale scores of tested nurses were significantly higher after training (t = -18.950, P < .001) than before the training. At result level, the clinical nurse innovation ability of tested nurses after the training were higher than before the training (t = -26.275, P < .001). The numbers of patent applications, granted patents, application for scientific research projects, sponsored scientific research projects, and papers published by team members after the training were larger than those before training (Z = -2.032, P = .042). Kirkpatrick's model can evaluate the effectiveness of nursing innovation training for clinical nurses. The nursing innovation training is beneficial to improve nurses' innovation capacity, organizational innovation climate and innovation self-efficacy, and nursing innovation behaviour and promote the output of research and innovation projects. Managers can flexibly develop training modules with regional characteristics based on this programme to effectively improve the innovation ability of clinical nurses, thus meeting the urgent demand for innovative nursing talents and the rapid development of nursing disciplines.

Turning crowds into communities: The collectives of online citizen science.

Over the past two decades, a number of digital platforms have been developed with the aim of engaging citizens in scientific research projects. The success of these platforms depends in no small part on their ability to attract and retain participants, turning diffuse crowds of users into active and productive communities. This article investigates how the collectives of online citizen science are formed and governed, and identifies two ideal-types of government, either based on self-interest or on universal norms of science. Based on an ethnography of three citizen science platforms and a series of interviews with their managers, we show how different technologies – rhetorical, of the self, social, and ontological – can be diversely combined to configure these collectives. We suggest that the shift from individual projects to platforms is a defining moment for online citizen science, during which the technologies that sustain the collectives are standardized and automatized in ways that make the crowd appear to be a natural community.

Merchant development of the city of Yalutorovsk (XIX – early XX centuries)

The architecture of stone buildings, built at the expense and with the assistance of merchants and small traders, which form the basis of the architectural and historical environment of the center of Yalutorovsk, was considered. For the first time, on the basis of composition and style analysis of merchant buildings, the specifics of style directions in the architecture of the city were revealed. Changes in the functional purpose, the original appearance of historical objects and development in general were traced. The materials of complex scientific research and restoration project of two merchant trading houses and previously unpublished photo documents are presented.

A Novel Candidate Gene for Predisposition of Hodgkin Lymphoma; Pregnan X Receptor (PXR)

ObjectiveHodgkin lymphoma (HL) is a lymphoproliferative malignancy of B-cell origin and one of the common tumors in adolescent and young adults. Less than one percent of HL patients have a family history and siblings of the affected individual may have an increased risk of developing the disease. HL risk is associated with immunodeficiency syndromes. Clustering of cases of HL within families may also suggest a genetic predisposition. In cases with familial clustering, recognition of genetic predisposition genes in the pathogenesis of HL may offer therapeutic benefits, and provide genetic counseling and surveillance for the family members for early diagnosis. We had previously reported CD70 signaling defect in an extended family with multiple consanguineous marriages and individuals affected with Hodgkin lymphoma and/or immune deficiency (J Clin Immunol.2020, 40(6):883-892). The aim of this study is to investigate for a cancer predisposition gene/condition in two siblings with HL, whose parents had a consanguineous marriage.Material and MethodsA 10 year-old girl with progressive HL was referred for further evaluation and treatment. She had been diagnosed with stage IIIBs HL, nodular sclerosing subtype and had received chemotherapy (ABVD) where she was reported to have partial response, followed by progressive disease. The tumor was CD30 positive. At admission, the patient had a massive enlarged mediastinum due to conglomerate lymph nodes, nodules in the lung, lymph adenomegalies in the cervical, supraclavicular, axillary regions. She was treated with ifosfamide+mesna, etoposide, carboplatinum (ICE) and brentuximab and achieved a complete metabolic response in PET-CT evaluation after six courses. She is transferred to receive stem cell transplantation. Her 24 year-old sister was also diagnosed with early stage HL during pregnancy, had a healthy delivery, was treated with chemotherapy and was in remission.In this study, we performed exome sequencing of the index case (IV-7). The elder sister who was diagnosed with HL and the parents, whose informed consents were taken. There were five children in the family; two of the girls were (IV-7 and IV-11) diagnosed with HL, a boy (IV-8) with inflammatory skin findings, a sister (IV-9) and a cousin (IV-13) with suspected lymphoma, and a healthy girl (IV-10) (Figure 1). After quality control and alignment steps, variants were annotated using ANNOVAR, dbSNP, and ExAC. Variant evaluation was performed by in-house filtering steps based on MAF<0.1%, CADD score >10, SIFT, PolyPhen, MutationTaster, FATHMM scores. We also used Pediatric Cancer Variant Pathogenicity Information Exchange (PeCanPIE) tool for identification and classification of the variants.ResultsA germline homozygous missense gene variation (c.928 G>A, p.D310N, rs144833620) was identified on the ligand binding domain of the Pregnane X Receptor Gene (PXR or NR1I2) gene. Sanger sequencing confirmed the familial segregation; IV-7 and IV-11 HL cases were homozygous and parents (III-13 and III-14) were heterozygous. The index case did not have elevated EBV-DNA PCR levels. Index case had increased CD3, CD2 and CD8 and reduced CD4 levels.(Conclusion)The PXR encodes a member of the nuclear receptor (NR) superfamily and functions in the metabolism and elimination of xenobiotics and several commonly used drugs. Heterodimerization of PXR and RXR (functional partner) lead to conformational changes upon ligand binding, functions as the transcriptional regulator of PXR target genes including metabolizing enzymes, drug transporters, inflammation and cell cycle associated genes. Previously reported Pxr-/- animal model showed that mice lacking the steroid and xenobiotic receptor develop B cell lymphoma. However, there is no case of HL published linked to variation in PXR gene. Clustering of cases of HL within families, especially in families with consanguineous marriages should suggest a genetic predisposition. The PXR seems to be a novel candidate gene for predisposition of HL.Funding: This study was funded by Scientific Research Projects Coordination Unit of Istanbul University with a project number TDK-2020-37127.

Study on Discovery Method of Cooperative Research Team Based on Improved Louvain Algorithm

According to the needs of scientific research project research and development, the research of cooperative team excavation methods was carried out. Aiming at the current difficulties in accurately and reliably defining and identifying cooperative research teams from co-author network, an improved Louvain algorithm that integrates core node recognition was proposed: Louvain-LSCR algorithm. Based on the analysis of the Louvain algorithm, considering the local topology of the node in the network and the communication range of the node, a new algorithm LSCR for core node identification was constructed. The LSCR algorithm and Louvain algorithm were merged to obtain a new and improved algorithm, Louvain-LSCR. In this algorithm, the leaf nodes in phase 1 of Louvain algorithm were first pruned to reduce calculations; then, seed nodes were selected according to the LSCR algorithm in phase 2. The experimental results on related datasets show that LSCR algorithm has certain advantages in identifying core nodes. The modularity of Louvian-LSCR algorithm is better than other algorithms, and the community structure is more reasonable. It was verified that the algorithm can mine potential cooperative research teams in co-author network.

Managing the Hazards of Aeolian, Fluvial and Coastal Erosion in Gudhi Area-Northern Kuwait Bay

Kuwait Institute for Scientific Research plans to set up some research facilities within the Gudhi area, which lies north of the coastal spill of Kuwait Bay. The area is about 653,000 m2, the region highly sensitive from an environmental perspective and ecological. It is a coastal strip dominated by rich fauna and flora mainly Nitraria retusa forming large nabkhas that attract many wildlife scientists. The presence of nabkhas is a good indicator of fluvial and aeolian activities in the area. The establishment of infrastructures within this area is anticipated to cause significant damage to wildlife. Additionally, any future infrastructures in the area is under the following threats: 1-S and encroachment as it is located within an active wind corridor. 2-Fluvial action during flood seasons as it is located at downstream of Jal Al-Zur watershed. 3-The wave erosion along 1200m coastal margin. As an important role of KISR is the attention and care regarding the environmental aspects associated with project actions, therefore, it is proposed that a proper scientific research project should be implemented prior to the establishment of any infrastructure development. The main objective of this study is to assess and control hazards in the Gudhi area by implementation of native plants and mangroves landscape design. Assessment and monitoring of fauna and flora have provided initial information on existing vegetation, soil properties that are considered important to quantify ecological conditions prior to actual vegetation plantation establishment or restoration effort. Nitraria and Lycium populations were found the most proper in controlling hazards of mobile sand and flush floods for the study area.

Ten best practices to strengthen stewardship and sharing of water science data in Canada

AbstractWater science data are a valuable asset that both underpins the original research project and bolsters new research questions, particularly in view of the increasingly complex water issues facing Canada and the world. Whilst there is general support for making data more broadly accessible, and a number of water science journals and funding agencies have adopted policies that require researchers to share data in accordance with the findable, accessible, interoperable, reusable (FAIR) principles, there are still questions about effective management of data to protect their usefulness over time. Incorporating data management practices and standards at the outset of a water science research project will enable researchers to efficiently locate, analyse and use data throughout the project lifecycle, and will ensure the data maintain their value after the project has ended. Here, some common misconceptions about data management are highlighted, along with insights and practical advice to assist established and early career water science researchers as they integrate data management best practices and tools into their research. Freely available tools and training opportunities made available in Canada through Global Water Futures, The Gordon Foundation DataStream, the Digital Research Alliance of Canada Portage Network, Compute Canada, and university libraries, among others are compiled. These include webinars, training videos, and individual support for the water science community that together enable researchers to protect their data assets and meet the expectations of journals and funders. The perspectives shared here have been developed as part of the Global Water Futures programme's efforts to improve data management and promote the use of common data practices and standards in the context of water science in Canada. Ten best practices are proposed that may be broadly applicable to other disciplines in the natural sciences and can be adopted and adapted globally.

Scientific Tourism in the French Alps: A Laboratory for Scientific Mediation and Research

This contribution focuses on scientific mediation implemented within scientific tourism initiatives in mountain areas. Three case studies in the French Alps support this research: the Jardin Alpin du Lautaret of the University of Grenoble Alpes, the CREA Mont-Blanc, a private research center organizing participatory science and student travel abroad programs and the scientific hut to hut trekking routes in the Écrins National Park, organized jointly with a scientific research project (Labex ITEM, Reflab). Scientific tourism and mediation are first defined. Next, a quantitative and qualitative approach (with interviews and participant observations) allows us to understand the impact and role of scientific mediation within tourism. Results show a high level of interest of the issue within involved publics and a close connection between experience and knowledge. It appears that it is also a tool for public awareness of the challenges of our modern societies.

Complementary and Integrative Medicine in academic health education

ObjectiveTo analyze academic education in Complementary and Integrative Medicine (CIM) according to university students from the health area. MethodsCross-sectional study with 1399 students from six public and private Brazilian universities, with online and in-person collection of socioeconomic, demographic, educational and academic data, carried out in 2019. The bivariate analysis was applied for the outcome “presence of CIM in academic health education”, using the SPSS Statistic program, version 23.0™. ResultsThe prevalence of the presence of CIM in academic health education was 52.3%, being 31.1% in the compulsory and 8% in the non-compulsory curricular education, 2.0% in scientific research and 4.7% in university extension activities. There was an association of the outcome with knowledge of the national CIM policy (OR = 5.258; p = 0.000), of which knowledge can be indicated and used in one’s professional area (OR = 4.836; p = 0.000), interest and/or use of CIM by the teachers/tutors of the course (OR = 3.955; p = 0.000), stimulus by the university to carry out scientific research (OR = 3.277; p = 0.000) and university extension projects with CIM (OR = 3.686; p = 0.000). ConclusionAcademic education using CIM in health area courses is not very prevalent in teaching, research and university extension in Brazil, but when present in the curricular and non-curricular educational processes, it shows a significant association with knowledge, skills and their use by university students. The creation of a National Educational Planning in CIM is a vital imperative.

Sensitivity to external optical feedback of circular-side hexagonal resonator microcavity laser* *Project supported by the National Key Research and Development Program of China (Grant No. 2019YFB1803500), the National Natural Science Foundation of China (Grant Nos. 61705160, 61961136002, 61822509, and 61875147), the “1331 Project” Key Innovative Research Team of Shanxi Province, China, and the National Defense Basic Scientific Research Project (Grant

The sensitivity to fault reflection is very important for larger dynamic range in fiber fault detection technique. Using time delay signature (TDS) of chaotic laser formed by optical feedback can solve the sensitivity limitation of photodetector in fiber fault detection. The TDS corresponds to the feedback position and the fault reflection can be detected by the laser diode. The sensitivity to feedback level of circular-side hexagonal resonator (CSHR) microcavity laser is numerically simulated and the feedback level boundaries of each output dynamic state are demonstrated. The peak level of TDS is utilized to analyze the sensitivity. The demonstration is presented in two aspects: the minimum feedback level when the TDS emerges and the variation degree of TDS level on feedback level changing. The results show that the CSHR microcavity laser can respond to the feedback level of 0.07%, corresponding to -63-dB feedback strength. Compared to conventional distributed feedback laser, the sensitivity improves almost 20 dB due to the shorter internal cavity length of CSHR microcavity laser. Moreover, 1% feedback level changing will induce 1.001 variation on TDS level, and this variation degree can be influenced by other critical internal parameters (active region side length, damping rate, and linewidth enhancement factor).

Assessment of the development of innovation activities in the regions: Case of Ukraine

The development of innovation activities is of great importance on the path to achieving the goals of sustainable development. Success on this path is closely related to the presence of comparable information on the development of innovation activities at the regional level. The aim of the paper is to assess the development of innovation activities in the regions of Ukraine and identify differences in results. The study is performed using relative indicators for the assessment of the development of innovation activities in the regions of Ukraine. The indicators were averaged and normalized. To analyze how innovation activities change over time, the dynamic indices based on the geometric mean of the growth rate of the relative indicators were used. The obtained results have significant differences in the regions being assessed. Most regions have a heterogeneous development of innovation activities. At the same time, they are at the top and bottom of the rankings of the regions in different indicators of the development of innovation activities. Only Cherkasy and Zaporizhzhia oblasts are at the top of the rankings in at least 75% of indicators. However, in 2017‒2019, all indicators improved in at least 29% of regions. In addition, 75% of indicators improved in at least 54% of regions. Therefore, over time, most regions progressed in the development of innovation activities. Management decisions for the development of innovation activities should be complex for all regions and implemented primarily in the regions where there is no improvement over time. AcknowledgmentsThe paper is prepared within the scientific research project “Sustainable development and resource security: from disruptive technologies to digital transformation of Ukrainian economy” (No. 0121U100470).

Otolaryngology Residents' Attitudes, Experiences, and Barriers Regarding the Medical Research.

Objective:It was aimed to investigate the attitudes, experiences, and barriers towards scientific research among otolaryngology residents in Turkey.Methods:Anonymous data were collected via an online survey. The demographic characteristics and experience in scientific research were investigated in the first section of the survey. The attitudes of participants towards scientific research and the barriers to the scientific research were examined in the second section of the survey using 17 items.Results:The present study involved 119 otolaryngology residents continuing their education. It was determined that 68.1% of participants think that “participating in scientific research” is a part of otolaryngology training. In the present study, it was shown that the residents having journal club hours in clinics on regular basis participated in various steps of scientific research projects (p<0.05). Residents stated that they participated in the “literature review” stage of the preparation of a scientific publication (mean value of 2.58±1.88) most and in “verbal presentation in a congress” least (mean value of 0.74±1.44). It was determined that 80.7% of participants have not attended in any training on scientific research. It was found that the residents receiving structured scientific research training participated more in steps of scientific research projects which was statistically significantly (p<0.05).Conclusion:In our country, otolaryngology residents are very enthusiastic about having research education and participating in researches. However, residency students frequently have time deficiency, lack of knowledge-skill, and lack of financial support. Dedicated time should be allocated for research training and practice in specialty programs. Journal club activities should be organized on regular basis and integrated with research education. On the other hand, the scholarly activities of residents should be supported by means of various countrywide educational activities on research training.

Two-proton radioactivity of ground and excited states within a unified fission model * *Supported by the National Natural Science Foundation of China (U1832120, 11675265), the Natural Science Foundation for Outstanding Young Scholars of Hebei Province of China (A2020210012, A2018210146), the Natural Science Foundation of Hebei Province of China (A2021210010), the Continuous Basic Scientific Research Project (WDJC-2019-13) and the Leading Innovation

A unified fission model is extended to study two-proton radioactivity of the ground states of nuclei, and a good agreement between the experimental and calculated half-lives is found. The two-proton radioactivity half-lives of the ground states of some probable candidates are predicted within this model by inputting the released energies taken from the AME2020 table. It is shown that the predictive accuracy of the half-lives is comparable to those of other models. Then, two-proton radioactivity of the excited states of 14O, 17,18Ne, 22Mg, 29S, and 94Ag is discussed within the unified fission model and two analytical formulas. It is found that the experimental half-lives of the excited states are reproduced better within the unified fission model. Furthermore, the two formulas are not suitable for the study of two-proton radioactivity of excited states because their physical appearance deviates from the mechanism of quantum tunneling, and the parameters involved are obtained without including experimental data from the excited states.
