Authors: Singh Ashutosh , Mishra Kartikeya , Kumar Sourav , Shankar Chandra
Published: May 2023

Abstract: An intelligent manhole cover management system is a crucial foundation in a smart city to effectively prevent frequent accidents related to manhole covers. Proper management of the drainage system is essential for ensuring the safety of residents. Regular inspections alone can lead to flooding and blockages in the drainage system. The displacement, relocation, and deterioration of manhole covers pose serious risks to personal safety, which contradicts the goals of smart city development. The system incorporates multiple sensors to monitor the status of manholes, including detecting lid openings, cover theft, and temperature variations. Additionally, this paper aims to analyze real-time levels of toxic gases. If the gas levels exceed the predetermined threshold, alerts will be sent to the authorized individuals through their connected mobile devices, even if they are remotely located.
DDoS Attack Detection using ML
Authors: Kasture Pradnya
Published: May 2023

Abstract: DDoS attacks are an attempt to prevent the service from being unavailable by overloading the server with malicious traffic. In the past few years, distributed denial of service attacks is becoming the most difficult and burdensome problem. The number and magnitude of attacks have increased from few megabytes of data to 100s of terabytes of data these days. As there are different attack patterns or new types of attacks, it is difficult to detect such attacks effectively. New techniques for generating and mitigating distributed denial of service attacks have been developed in the present paper, which demonstrate that they are far superior to those currently used. In addition, in order to carry out a thorough investigation of the challenges presented by distributed denial of service attacks, we classify DDoS attack methods and techniques used for their detection. We're comparing the attack module to a few other tools out there.

Published: May 2023

Abstract: A lot of democratic choices are made among many different sets of people, and voting is the preferred way of doing so. The technique offers an equitable and effective way to make a choice based on the consensus, regardless of whether it is applied in formal or informal settings. Keeping track of voter choices is not difficult when fewer people are voting, but it becomes crucial and more difficult when there are thousands or even millions of voters. Modern voting processes face a record-keeping challenge, but advances in blockchain technology may offer a solution. This is because blockchain technology, by its very nature, shines in apps where numerous users are working with immutable data. This study examines the planning and Election Tally Application a voting system being developed that has its blockchain, operates on a centralized network of servers, and incorporates a biometric scanner to ensure vote accuracy and tell enrolled voters from inactive ones. This system enables data immutability while giving voter protection and ballot management. The system can scale to manage a large number of votes from numerous servers while keeping data integrity, speed, and security, according to experimental findings. To improve user security, user identification was integrated into developing and implementing the centralized and autonomous blockchain network for use as a voting platform

Abstract: The advancement of blockchain innovation has prompted the making of decentralized applications (DApps), which permit client collaboration without the utilization of mediators. One of the most generally used blockchain stages for making DApps is Ethereum, which conducts business utilizing its own cash, Ether. Using Metamask, React.js, Node.js, and Solidity, we demonstrate the design and implementation of a decentralised system for Ethereum transfer in this paper. Our technology allows users to safely move Ether between accounts without the usage of intermediaries. We use React.js and Node.js to make the web application, a program module called Metamask to communicate with Ethereum, and Solidity to make the brilliant agreements that make exchanges conceivable.

Quantum Rabi interferometry of motion and radiation
Authors: Park Kimin , Marek Petr , Andersen Ulrik L. , Filip Radim
Published: May 2023

The precise determination of a displacement of a mechanical oscillator or a microwave field in a predetermined direction in phase space can be carried out with trapped ions or superconducting circuits, respectively, by coupling the oscillator with ancilla qubits.

Through that coupling, the displacement information is transferred to the qubits which are then subsequently read out. However, unambiguous estimation of displacement in an unknown direction in the phase space has not been attempted in such oscillator-qubit systems. Here, we propose a hybrid oscillator-qubit interferometric setup for the unambiguous estimation of phase space displacements in an arbitrary direction, based on feasible Rabi interactions beyond the rotating-wave approximation. Using such a hybrid Rabi interferometer for quantum sensing, we show that the performance is superior to the ones attained by single-mode estimation schemes and a conventional interferometer based on Jaynes-Cummings interactions. Moreover, we find that the sensitivity of the Rabi interferometer is independent of the thermal occupation of the oscillator mode, and thus cooling it to the ground state before sensing is not required. We also perform a thorough investigation of the effect of qubit dephasing and oscillator thermalization. We find the interferometer to be fairly robust, outperforming different benchmark estimation schemes even for large dephasing and thermalization.
Intersections Between Fintech Imaginaries and Traditional Banking: A Study of Disciplinary, Implementary, and Parasitic Work in the Danish Financial Sector
Authors:   , Kværnø-Jones Jack
Published: May 2023

This PhD project studies intersections between the financial technology sector (FinTech) and traditional banking, approached as sites in which imaginaries, such as those pointing to ‘disrupted’ futures of banking, intersect with established organisational contexts of traditional banking. The focus on intersections departs from a curious puzzle presented by the FinTech sector, in which activity in the sector is characterised by both imaginative visions of transformed financial services and connections to traditional banking. The thesis suggests the concept imaginative intersections, which hones in on intersections between imagination and established organisation. In studying imaginative intersections, the thesis is guided by the question: ‘How do FinTech imaginaries intersect with established contexts of traditional banking?’ This research question is motivated by a broader interest in how imagined possibilities are delimited within established organisational contexts. The thesis engages with discussions across science and technology studies (STS), anthropology, and cultural economy concerned with finance, technology, and imagination, thinking about the kinds of worlds instituted through actors grappling with financial technological developments. A burgeoning research agenda on imagination in organisation studies is then fleshed out, drawing together different works that point to a growing interest in the significance of imagination in organisational activities. Within the emerging research agenda on imagination in organisational research, the thesis hones in on a particular tension between imagination and established organisational contexts, arguing that we should be attentive to the organisational work involved in making certain imagined futures performative.

Published: May 2023

Malays have long been stereotyped with certain negative characters and this has been prompting for decades. They had been blamed for their inability to compete against other races in many aspects. The main objective of this study is an exploration of how British writers stereotyped the images of the native Malays through texts. A thematic content analysis involving articles published by Singapore Free Press were analysed for this purpose. The findings showed that some of the contents of the articles were misleading and far from being accurate. The British managed to portray Malays as lazy and apathy through the publications. These accusations were not explained in an intellectual manner, a result of civilizational and cultural discrepancies between the British colonial writers and their Malay subjects. Such stereotype was actually being planned ahead to legalized the colonization in the Malay land.
PENGARUH ETNIK DALAM PEMBENTUKAN PARTI-PARTI POLITIK AWAL DI SARAWAK, 1959-1963
Authors: Junaidi Anita , Wan Mat Ali Noorlizawati
Published: May 2023

This paper discusses the influence of ethnicity in the formation of early political parties in Sarawak. The cession of Sarawak to the British government has led to the emergence of the people’s nationalism awareness leading to the formation of political parties in Sarawak. Discussion is done through the library method by analysing books, dissertation and articles by previous researchers. The results of this study found that the plurality of races in Sarawak played a significant role in shaping the political pattern in Sarawak. The evidence can be seen in the formation of political parties that are heavily influenced by racial elements. Thus, ethnic factors have become the main factor in the formation of political parties in Sarawak. This considering that the purpose of establishing the parties is to safeguard the interests of their respective races. Therefore, the influence of ethnicity in a party can be seen according to the composition of party membership which is dominated by certain races. However, there are also several other factors that influence the formation of early political parties in Sarawak. Among them are, differences in idealism, the effects of the 1956 municipal elections, the desire for independence, regional sentiments and the influence of a party's ideology. Overall, this study can disclose to the public that the racial nature has been rooted in political parties in Sarawak since the beginning. Therefore, it is suggested for the future studies, the researcher can analyse whether this race-based party has an impact on the political development in Sarawak.
“ISIM” DAN “ISI” DALAM PERSEMBAHAN SENI PERMAINAN KUDA KEPANG
Authors: Ahmad Siti Islamiah , Samsuddin Mohd Effindi , Awang Pawi Awang Azman
Published: May 2023

The art of “permainan” Kuda Kepang is a type of dance that goes through a ritual process before reaching a trance state during the performance. The current study focuses on the keywords “isim” and “isi, which refers to the form of practice taken and performed by Kuda Kepang players. This investigation focuses on the relationship between the possession of “isim” within the player and the filling of “isi” in the Kuda Kepang equipment to realize the presence of the trance state during the performance. Therefore, the objective of this study is to identify the factors contributing to the occurrence of the trance state during the performance. The data in this research were obtained through field studies with four active Kuda Kepang groups in the state of Johor. The content and factors that cause the trance state are analysed based on the philosophy of the Kuda Kepang game containing the relevant element. The qualitative research design produced data obtained from observation, interviews, and documentation. The results of the investigation show that players who experience the trance state possess “isim”, while the performance equipment used has “isi”. The trance state has a close relationship with the ritual process performed before the performance, which is also related to the possession factor of “isim” and “isi”. Without “isim” within the player and “isi” in the music equipment, the trance state during the performance would not occur, even if the ritual has been performed. This study highlights the importance of “isim” and “isi” in the success of the ritual process and the occurrence of the trance state. Further research can be conducted on the possession of “isim” and the content of the “isi” in Kuda Kepang performances.
PEMETAAN TABURAN LEKSIKAL DIALEK MUAR: SATU KAJIAN RINTIS
Authors: Nopiah Julaina , Azhar Shazriena Izlin , Rosly Nurul Jamilah
Published: May 2023

Dialect is one of the language variations spoken by the community in a certain area to interact with each other. Although the use of dialects in a state does exist, the diversity of sub-dialects is still visible in the eyes of most people. The city of Muar, which is located in the state of Johor, is one of the regions that thrives on the existence of various sub-dialects. With the help of the Geographic Information System (GIS) application, this study focuses on identifying the spread of lexical variants of the Malay dialects found in Lenga, Bukit Kepong and Gombang and further describes the spread factors. This study fully uses the field research method involving a total of six study informants and 60 study respondents. The findings of this study show as many as six lexicals with different variant usage while there are nine lexicals that have the same dialect of use in Lenga, Gombang and Bukit Kepong. In addition, this study also shows that there are three factors that spread the variant between these three areas, among them demarcation, landform and space (spatial) and migration. As a result, the implementation of this study proves that the variety of variants in the three areas located in the Muar district brings uniqueness and becomes a heritage and a symbol of pride of the local community. Because the current study serves as a preliminary research on the Muar dialect mapping, the analysis of this study is done at the level of descriptive explanation. Researchers also did not focus on specific lexicons in lexical distribution mapping. Therefore, further studies are suggested to focus on specific lexicons to show the speech variants of the local dialect. Subsequent studies are also recommended not only to focus on lexical distribution mapping but also to present the lexical distribution through the Isogloss Map used.
Imagined Communities of English Use in JET Programme Teaching Materials
Authors: Brown Charles Allen
Published: May 2023

Visualizing oneself joining imagined communities of target language (TL) use represents a potent motivation for language study. Given that rationales for the Japan Exchange and Teaching (JET) Programme include fostering internationalization, a student-centered classroom, and communicative skills, teaching to promote learners envisioning themselves gaining access to different imagined social groups via the TL is further warranted in this program. Yet no research has examined the actual role of imagined TL communities in JET teaching. This project responded by investigating how JET participants foster imagined communities of English use among learners. Materials produced by JET teachers from across Japan were collected with a content analysis being undertaken to determine how they portrayed connections between the language and social group participation. Results of this analysis of 5079 teaching materials indicated that most (2783) involved language practice divorced from social connections. The remainder ran the gamut from lessons in which social group information was tangential and not connected to particular language to a smaller number in which connections between language and potential future social group participation were strong. These results suggest that the possibility of leveraging connections between language and social group participation to promote imagined communities of TL use among learners is possible within the JET paradigm and that this avenue for learner motivation could be further exploited. Given the importance of these findings for motivation coupled with the adoption of initiatives similar to JET across Asia, these results have implications both within and outside of the JET Programme.
Hugging Atmospheres
Authors: Elena Mooibroek
Published: May 2023

The main question around this research paper is how can we translate ambiances? This ungraspable ‘something’? What is our relationship with the atmosphere of spaces that brings out our emotional state? Can we characterize atmospheres by simply giving them names? Giving them a place for their selves to develop.

I researched six certain atmospheres, Masculinity, Sound, Death, Warmth, Lust, and Serenity. They are the ones that I went through most recently before writing this research paper. I wanted them to all come together and hopefully come across an answer on how they might be useful in day-to-day life as an artist in creating art, but also in general, can we understand each other better while talking about them? They are unseen yet as important as our imagination.

Hoping for a translation of the ungraspable ‘something’. Into moments of poetry and storytelling to get a grip on where they touch each other. Giving them a platform/to create a world where atmospheres/ambiances are more visible. To have conversations with them to create an understanding of what they mean. And how they would look like. Along the way I figured, one can not stand on one’s self, they are all in need of the other. Which seems like a reflection of our reality.

This paper studies the exact solutions and dynamic properties of the
stochastic governing model for embedded solitons with χ 2 and χ 3
nonlinear susceptibilities. We propose a new trial equation method to
find the exact solutions of the model. We also analyze the dynamic
properties of the model equation by complete discriminant system for
polynomial method. In addition, we assign specific values to the
parameters to prove the existence of exact solutions, and giving the
two-dimensional diagrams to demonstrate the dynamical behavior of the
model. The obtained abundant exact solutions are beneficial for better
study of the stochastic perturbation model of optical solitons.

Authors: Wang Jia , Li Wen-Wei , Wu Han-Biao , Li Meng-Ting , Qiu Zhi-Kun
Published: May 2023

Background: Atypical antipsychotic(AAP) augmentation is an
alternative strategy for patients with major depressive disorder(MDD)
who had an inadequate response to antidepressant therapy. We aimed to
compare and rank the efficacy and safety of 4 AAPs in the adjuvant
treatment of MDD. Methods: We searched randomized controlled
trials(RCTs) published and unpublished from the date of databases and
clinical trial websites inception to April 30, 2022. The risk of bias
and certainty of the evidence is assessed using the Cochrane bias risk
tool and GRADE framework, respectively. Based on the random effects
model, we estimated summary risk ratios (RRs) or standardized mean
difference (SMD) using network meta-analysis. This study is registered
with PROSPERO, number CRD42012002291. Results: 57 eligible RCTs
comprising 10900 participants were included. In terms of primary
efficacy outcome, compared with placebo, all AAPs had significant
efficacy ( SMD= -0.40; 95% CI, -0.68 to -0.12 for quetiapine; -0.35,
-0.59 to -0.11 for olanzapine; -0.28, -0.47 to -0.09 for aripiprazole
and -0.25, -0.42 to -0.07 for brexpiprazole, respectively). In terms of
acceptability, no significant difference was found, either agents versus
agents or agents versus placebo. In terms of tolerability, compared with
the placebo, quetiapine (RR= 0.24; 95% CI,0.11-0.53), olanzapine
(0.30,0.10-0.55), aripiprazole (0.39,0.22-0.69), and brexpiprazole
(0.37,0.18-0.75) were significantly less well tolerated. 8 (14.2%) of
56 trials were assessed as low risk of bias(RoB), 38 (67.9%) trials had
moderate RoB, and 10 (17.9%) had high RoB; In accordance with the
GRADE, the certainty of most evidence was low or very low.
Limitations: The overall quality of evidence is low, and the
long-term benefits of AAPs are unclear. Conclusion: Adjuvant
AAPs had significant efficacy compared with placebo, but treatment
decisions need to be made to balance the risks and benefits.
Reconfigurable Intelligent Surface Assisted DOA Estimation under Strong Interference
Authors: Xuechun Wang , Huang Kaizhi , Xu Xiaoming
Published: May 2023

Reconfigurable intelligent surface (RIS) has attracted a lot of
attention due to its capability to intelligently change the wireless
propagation environment. However, the accuracy of direction of arrival
(DOA) estimation in strong interference environment will be seriously
affected. In this paper, a RIS aided system for DOA estimation is
developed and analysed for non-line-of-sight (NLOS) scenarios. Unlike
traditional DOA estimation systems, a low-cost system with only one
full-functional receiver is given by changing the phases of the
reflected signals at the RIS elements to realize the multiple
measurements. Moreover, a new method based on the corrected projection
jam algorithm is proposed for the DOA estimation by constructing the
orthogonal projection matrix of the jamming subspace as a block matrix,
so as to constrain the strong interferences. Furthermore, the phase
shift matrix design of RIS elements is transformed into a specific
objective optimization problem and then solved by fractional
programming. Simulation results show that the proposed method achieves
computational complexity in the RIS-aided strong interference system
with only one receiving channel than various benchmark schemes.
Genetic Variability of Isolated Eastern Alpine Populations of Linnaea borealis L., Characteristic Species of Boreal Forests, Indicates ‘in situ’ Glacial Survival
Authors: Pipenbaher Nataša , Kaligarič Mitja , Škornik Sonja , Ivajnsic Danijel , Šiško M.
Published: May 2023

In a rapidly changing environment, because of habitat loss and
fragmentation, many plant species have become rare. We investigate
genetic variability between two small isolated populations of twinflower
from the Eastern Alps and three population from the core Boreal
distributional range. The results revealed three main clusters,
exemplars from the Boreal range are present in all three clusters. Very
low genetic variation within the two isolated Alpine populations and
very high genetic variation between the two Alpine populations was
found, despite their being only 73 km apart. Moreover, a low proportion
of distinct genotypes were found in the Alpine populations in comparison
to the Northern one. We conclude that the two isolated Alpine
populations are both glacial relict populations, based on the high
genetic variability between them, probably due to consecutive
bottlenecks and long-term isolation under specific environmental
conditions. However, glacial relicts, usually associated with vulnerable
habitats deserve urgent attention involving conservation countermeasures
especially from the perspective of climate change.
Influence of socioeconomic drivers on land use and cover changes using Remote sensing and GIS in Dar es Salaam, Tanzania
Authors: Simon Olipa , Lyimo James , Yamungu Nestory
Published: May 2023

Understanding human interactions demands modelling human-environment
interactions. This study uses remote sensing and machine learning to
evaluate land use and land cover (LULC) changes over 27 years in Dar es
Salaam Metropolitan City, Tanzania, and the spatially varying
relationships between LULC changes and socioeconomic driving factors.
LULC change values and factors are retrieved from data points generated
by regular sampling methods. The geographically weighted regression
(GWR) model is then employed to analyse the relationships between LULC
changes and the identified factors. The analysis of LULC changes reveals
a dynamic transformation in land cover between 1995 and 2022,
characterised by a notable 14.9% increase in built-up areas and a
corresponding decline of 14.6% in bushland. 65.8% of the land cover
experiences gains and losses, while 34.2% remains relatively stable
over the 27 years. The GWR model surpasses the OLS model, achieving an
R value of 0.73, signifying a strong
association between LULC changes and the identified socioeconomic
factors, explaining 73% of the LULC variation. Additionally, the
influences of these factors, including the signs, significances, and
coefficient values, exhibit considerable variations across different
LULC change types. Notably, population density and proximity to the city
centre significantly contribute to LULC changes, whereas the impact of
gross domestic product and distance to roads is comparatively lesser.
Moreover, poverty does not significantly drive LULC changes. This
study’s findings suggest that urbanisation and urban sprawl, as
indicated by population density and distance from the city centre,
significantly influence land cover changes in the study area.
Compact LTCC Diplexer With High Frequency Selectivity and High Isolation
Authors: Qian Kewei , Chen Xiangru
Published: May 2023

This paper proposes a design method of low temperature co-fired
ceramic(LTCC) diplexer, which is used to separate GPS and ISM band
signals, achieves high iso lation and miniaturization, and can be used
in electronic consumer products. The diplexer is composed of a low-pass
filter and a band-pass filter. The antenna sep arates the received mixed
signals according to frequency bands, and enters their respective
processing modules through two output ports. The size of the diplexer is
1.6mm*0.8mm*0.6mm, the insertion loss is less than 0.6dB for GPS
1.575GHz appli cation, the isolation is greater than 26dB, and the
insertion loss is less than 0.6dB for ISM 2.4/5GHz application, the
isolation is greater than 37dB. Compared with the reported LTCC
diplexer, the features of this diplexer are that the lower channel
occupies a smaller volume at lower frequency, and the higher channel
maintains low insertion loss in a wider bandwidth, and the passbands of
the two filters are close but still have high isolation.
New insights into tectonic relations between the Eastern Vardar Ophiolitic and Serbo-Macedonian units: Inferences from a microtectonic study in central Serbia
Authors: Males Maja , Randjelovic Nikola , Krstekanic Nemanja , Kostic Bojan , Ciric Nikolina , Stojadinovic Uros
Published: May 2023

A microtectonic study was conducted in the Levac region of central Serbia. Here, the tectonic contacts between the Europe-derived units, including the Serbo-Macedonian unit and Jurassic sedimentary cover of the European margin, and the Eastern Vardar Ophiolitic unit, are exposed at the surface. The results indicate that the contact zone underwent at least two ductile contractional deformation phases. The older contraction was associated with the formation of isoclinal folding and top-to-SE shearing in the immediate contact between the Eastern Vardar ophiolites and the Jurassic sedimentary cover of the European continental margin. This older contractional phase was likely associated with thrusting during the latest Jurassic obduction of the Eastern Vardar ophiolites over the European margin. The thrusting of the Eastern Vardar ophiolites created a sub-ophiolitic melange currently preserved in a narrow zone at their contact with the underlying Jurassic sediments, which in turn underwent metamorphism in the lower greenschist facies. The obduction- related deformation was highly overprinted by a younger, top-to-W contraction associated with the Cretaceous?Paleogene continental collision between Europe- and Adria-derived units.
Decision making in fuzzy closed loop dual channel supply chain
Authors: Mondal Animesh , Kumar Jana Ranjan , Kumar Jana Dipak
Published: May 2023

This paper discusses the optimal pricing and collecting decisions in a fuzzy environment of the three closed-loop dual-channel supply chain models where a manufacturer produces the original product from fresh materials and unfashionable products. The manufacturer sells the original products to the customers using direct and retail channels (forward dual channel). In the reverse channel, the manufacturer, third-party collector and retailer individually take responsibility for unfashionable products acquired from the market in the three models. Remanufacturing cost, product collecting cost and market demand are treated as fuzzy variables. The optimal decisions wholesale price, direct price, retail price and collection rate are derived using fuzzy set theory and game theory approach in the three decision models. Finally, numerical illustrations clarify the impact of the fuzzy degree parameters on the decision variables and the expected profits of the players. It is found that the manufacturer decision model is superior for receiving the maximum expected profits of the players and also being more convenient from the customer?s perspective.
The Effects of In-Group Identity and Clarity of the Bonus Determination Criteria on Supervisors’ Discretionary Bonus Adjustments: Field Evidence from China
Authors: Ho Joanna L. Y. , Lu Cody , Wu Anne
Published: May 2023

This study examines the influence of in-group identity between supervisors and subordinates and the clarity of the bonus determination criteria on supervisors’ discretionary adjustments of subordinates’ bonus compensation through the lens of social identity theory. Using field data from a multinational manufacturing company’s subsidiary in China, we find that in-group sales agents receive higher bonus awards and that this effect is more pronounced when there is high clarity of the bonus determination criteria. Additional analysis shows that these effects hold for higher-tenured sales agents and in regions characterized by lower sales agent turnover. Finally, we find that higher bonus awards are positively (negatively) associated with in-group sales agents’ future performance when there is low (high) clarity of the bonus determination criteria. Our findings hold potential implications for management practices in corporations operating in countries that have strong relationship-based cultures.

Published: May 2023

In obesity, CD11c+ innate immune cells are recruited to adipose tissue and create an inflammatory state that causes both insulin and catecholamine resistance. We found that ablation of Gnas, the gene that encodes Gαs, in CD11c expressing cells protects mice from obesity, glucose intolerance, and insulin resistance. Transplantation studies showed that the lean phenotype was conferred by bone marrow–derived cells and did not require adaptive immunity. Loss of cAMP signaling was associated with increased adipose tissue norepinephrine and cAMP signaling, and prevention of catecholamine resistance. The adipose tissue had reduced expression of catecholamine transport and degradation enzymes, suggesting that the elevated norepinephrine resulted from decreased catabolism. Collectively, our results identified an important role for cAMP signaling in CD11c+ innate immune cells in whole-body metabolism by controlling norepinephrine levels in white adipose tissue, modulating catecholamine-induced lipolysis and increasing thermogenesis, which, together, created a lean phenotype.

Article Highlights

We undertook this study to understand how immune cells communicate with adipocytes, specifically, whether cAMP signaling in the immune cell and the adipocyte are connected. We identified a reciprocal interaction between CD11c+ innate immune cells and adipocytes in which high cAMP signaling in the immune cell compartment induces low cAMP signaling in adipocytes and vice versa. This interaction regulates lipolysis in adipocytes and inflammation in immune cells, resulting in either a lean, obesity-resistant, and insulin-sensitive phenotype, or an obese, insulin-resistant phenotype.

Con base en metodología de investigación documental (Textual, Intertextual y Contextual), se busca establecer las condiciones de los diferentes sistemas administrativos relacionados con la salud como “completo bienestar”, más allá que la ausencia de enfermedad, y definir la relación que cada nivel de sistema tiene con el sector. El Sistema General de Seguridad Social en Salud -SGSSS- es más que asistencia: es respuesta económica frente a riesgos: reduce frecuencia, mitiga impactos, y supera el residual de impactos. Es, por lo tanto, un Sistema para la Administración de Riesgos -SAR- La “Salud” (OMS), como “completo bienestar”, facilita ver el SGSSS dentro del Sistema de la Protección Social -SPS- con Manejo Social del Riesgo -MSR- a través del cual se llega al “completo bienestar” dada la diversidad de orígenes de los riesgos administrados por este SPS.

Idiopathic small bowel volvulus is a rare cause of acute intestinal obstruction by strangulation in adults and is defined by the twisting of a segment of the small bowel around its mesenteric axis with no obvious underlying congenital or acquired cause.

This article reports the case of a 56-year-old patient, chronic smoker and cannabis user, who was admitted with febrile occlusive syndrome and generalized abdominal contracture.

The abdominal CT scan showed a distension of the small intestines upstream of a probable small bowel volvulus, associated with signs of digestive distress.

Surgical exploration revealed a large peritoneal effusion of distressed fluid, with a volvulus of the distal small bowel causing 1.80 m of small bowel and coecum necrosis from 2.20 ADJ without rotational abnormality or docking defect.

This study aims to determine the effectiveness of the Problem-Based Learning model on mathematics learning to instill mathematical literacy in elementary school students. Quasi Experiment was chosen as the type of this research. The research population was the 5th-grade students at SD Muhammadiyah 08 Cilacap, with the research sample consisting of two classes, namely 5A and 5B. The instruments used are test and non-test instruments. Hypothesis testing was carried out using the independent sample t-test and paired sample t-test. The average score on the pretest before the treatment was 59.7 in class 5A and 55.95 in class 5B. The average pretest score in class 5A was 66.6, and 62.15 in class 5B. The post-test average score was 77.7 in class 5A and 91.8 in class 5B. The study results show that the PBL model influences the mathematical literacy of elementary school students and increases students’ learning outcomes.

Learning mathematics that can improve elementary school students' critical thinking skills is rarely done. Therefore, students' mathematical necessary thinking skills still need to improve. The realistic Mathematics Education (RME) learning model is expected to enhance mathematical critical thinking skills because of providing contextual problems to students. This study aims to determine the effect of the Realistic Mathematics Education (RME) learning model on students' critical thinking skills in mathematics. This research uses quasi-experimental research. The population in this study were students of class VI SDN 1 Kalikoa, Cirebon Regency. The sample selection in this study was carried out using a cluster random sampling technique to determine the experimental and control classes. In this case, two classes were selected: class VI A as the practical class and class VI B as the control class. The instrument for collecting data tests mathematical critical thinking skills on integer material. The results showed that the RME learning model is more effective than the direct learning model on students' critical thinking skills in mathematics. This is because the value of , and   at a significance level of 5% and DK of 40, which means , so H0 was rejected, and H1 was accepted. The results of this study can be used as input for teachers and prospective teachers to improve themselves concerning the teaching that has been done and the student's critical thinking skills that have been achieved by paying attention to the right learning model to improve students' critical thinking skills in mathematics.

Tuberculosis (TB) problem is still a challenge for Indonesia today. The World Health Organization reports that Indonesia is the third country with the highest TB burden globally. All component of society must take a role in dealing with the global TB problem to achieve Zero TB in 2050. As the implementation, the Pesantren 2 Primary Health Care conducted socialization in the Wali Barokah Islamic Center, Kediri City. Socialization about knowledge to residents of Islamic Center, this study aims to determine the essential characteristics of Islamic Center residents against TB disease. Questionnaires related to knowledge were filled out before and after explanation using PowerPoint and leaflet media. By using purposive, sampling method obtained 100 respondents. The survey results showed a significant increase in the knowledge of Islamic Center residents about TB disease after socialization in terms of signs and symptoms of the disease (p < 0.02), modes of transmission (p < 0.02), and methods of prevention of transmission (p < 0.01). Negative attitudes are still visible by stigmatizing TB sufferers from being ostracized (62.7%). The majority of subjects will go to health facilities (6.9%), but subjects still choose not to go for treatment (68%). The presentation of material about TB leads to reduce the burden of TB disease in TB endemic communities by modifying attitudes and behavior.

Eastern Caucasus is home to more than 30 peoples speaking Caucasian, Iranian and Turkic languages. Fusion of multiple migration flows together with the complex population structure of the Eastern Caucasus make it more difficult to analyze its gene pool: this is the most poorly studied one among all regions of the Caucasus. The study is aimed to identify the main patterns of the autosomal gene pool variation in this region. A total of 356 genomes of 29 ethnic groups were studied using the large panels of SNP markers: 243 genomes of 22 peoples of the Eastern Caucasus and 113 genomes of 7 peoples living in adjacent regions. The bioinformatics analysis involved the use of the ADMIXTURE ancestral component method and the gene pool variability principal component analysis (РСА). The hypothesis of three genetic strata, the interaction of which forms the structure of gene pool of the Eastern Caucasus, was put forward. The “Dagestan” stratum carries information about the gene pool of the ancient autochthonous population of the Eastern Caucasus. The “Iranian” stratum represents the legacy of ancient and middle-aged migrations surges of the Iranian-speaking population: it constitutes three quarters of the gene pool of modern Azerbaijan and about one third of the Dagestan peoples' gene pool. The “Steppe” stratum represents a negligible influence of the Eurasian steppe. Interaction of three genetic strata is only indirectly related to the peoples' linguistic affiliation, however, the association with linguistics is more obvious in the Caucasian-speaking peoples. Four genetically distinct groups of indigenous population of the Eastern Caucasus have been identified, the combination of which should be included in the characteristics of its autosomal gene pool: 1) Dargins, Laks; 2) Avars, Lezghins, Tabasarans, Aghuls, Rutul people, Tsakhur people; 3) Kumyks, Tat people and Azerbaijanis living in Dagestan; 4) Azerbaijanis and Talysh living in Azerbaijan. The directions of further research have been defined.
Organization of the social and psychological support service at a higher educational institution (by the example of the Yaroslavl State Medical University)
Authors: Startseva ON
Published: May 2023

The article presents the rationale for formation of the social and psychological support service at a higher educational institution by the example of the Yaroslavl State Medical University (YSMU). The service is of particular importance, as the initial period of study at a university is associated with significant shifts, breaking of pre-existing stereotypes, stress, high anxiety and internal stress. This is a complicated stage of a human life, when not only physical, but also mental health of a person is finally formed, needs, motivation and personality of a future doctor are created, affecting the rest of the life. So, a higher institution is interested in the formation of a favorable educational and pedagogical environment, preservation and strengthening of students’ health, better effectiveness of education and quality of knowledge, and, thus, prevention of being expelled from the University. It should be noted that the need in this area development is confirmed by survey of students from the YSMU. The obtained results confirmed that the students were interested in the development of social and mental aid and support. It was the basis for creation of the Center for Social and Psychological Support at the University. According to the survey, the students need this kind of aid. Supply of students with practical aid, social support and support of mental health of students, and prevention of social disadaptation are the main problems solved with the help of professionals from the Center for Social and Psychological Support of the Yaroslavl Medical University.
