Aging Population’s Effect on Economic Output
Authors: Xie Zhihan
Published: January 2024

This study investigates the economic implications of demographic aging, a phenomenon increasingly prevalent in both developed and developing countries. Utilizing the Solow-Swan model as the foundational framework for analysis, the research conclusively demonstrates that an increase in the proportion of the elderly population directly correlates with a measurable decline in aggregate economic output. This downturn is primarily attributed to escalating healthcare and pension expenditures, coupled with a diminishing labor force. The paper also conducts a rigorous evaluation of various policy interventions designed to alleviate these economic challenges. While the research explores options such as boosting birth rates, fostering technological advancements, and increasing savings rate, the study ultimately advocates for a more immediate and practical approach: the reintegration of the elderly into the labor market. Not only does this strategy sustains economic productivity, but it also capitalizes on the invaluable experience possessed by older workers. This research serves as an exhaustive resource for policymakers and scholars interested in the economic dimensions of demographic transitions.

Authors: Wei Mingshi
Published: January 2024

Absolute value detecting is widely involved in integrated digital circuits. Currently absolute value comparison happens frequently in digital integrated circuits such as RISC structure micro controllers. Considering the requirements of corresponding products, an 8-bit absolute value detector is designed and optimized in this essay. Compared with some similar magnitude comparators existing on the market, this scheme supports 2’s complement input to realize calculation and comparison of absolute values. The basic structure of the design is a Complementary Metal Oxide Semiconductor (CMOS) logic gate circuit which is redesigned in order to reduce the number of transistors involved. The circuit was then further optimized in size and source voltage based on logic effort theory. Based on that, the size of logic gates and V_DD are properly adjusted to optimize both speed and energy efficiency. The final version realized a 20.12% energy consumption when the delay is 1.5 times of minimum value. In the future, similar method could be applied for optimization of other digital circuits in order to improve the performance of corresponding produces.

Authors: Sun Chuhao
Published: January 2024

Myocardial infarction (MI) is the world's leading disabling and fatal disease. Currently, clinical treatment methods mainly include drug therapy, angioplasty, and coronary artery bypass grafting. These traditional treatment methods are difficult to repair damaged myocardial tissue and cannot restore normal necrotic and fibrotic myocardium. Therefore, it is imperative to improve the efficacy of traditional treatment methods and find new treatment strategies. More and more studies have found that stem cell transplantation can repair damaged myocardium, but stem cells transplanted to the affected site undergo oxidative damage, compression loss, and low cell survival and retention rates. At present, there is an urgent need to seek new methods that can effectively repair damaged myocardium and restore cardiac function. In recent years, with the development of regenerative medicine engineering and the continuous optimization of polymer technology and the development of new biomaterials, it has become a reality to create lost or functionally damaged tissues and organs through theoretical methods of biology and engineering, enabling them to have the structure and function of normal tissues and organs.

Biodiversity of Drosophila species at a new university campus in Kunshan, China
Authors: Wang Ruoyi
Published: January 2024

The project aimed to explore the biodiversity of Drosophila species in Kunshan using genomic approaches. DNA sequences, specifically the Cytochrome Oxidase I (COI) gene, were utilized as genetic "barcodes" to identify the organisms. Three wild-caught fruit flies and a D. melanogaster control were selected, and their DNA was isolated through PCR amplification of the COI gene. The PCR products were sequenced, and the results were used to create phylogenetic trees and uploaded to the Barcode of Life Database Student Data Portal (BOLD-SDP) alongside species photos. The results identified 10 Drosophila species, with 6 species remaining unchanged over two years and 3 new species discovered this year. One sample was identified as D. neohypocausta, a Chinese endemic species, which had appeared only in the last two years in Kunshan. However, its sample size was small, suggesting it may not be native to the area. Further research revealed significant genetic differentiation between different clades of D. immigrans, which likely explained the limited number of D. neohypocausta samples, as most D. immigrans species are confined to specific regions. To gain a comprehensive understanding of biogeographic, ecological, and evolutionary patterns across the Drosophila genus, expanded sampling and taxonomic revision are necessary, particularly for the large immigrans species groups that have been inferred as polyphyletic in some studies. This study underscores the importance of genomic approaches in taxon diagnosis and highlights the need for further exploration to uncover the intricate relationships within the Drosophila genus.

Authors: Lin Chenyi
Published: January 2024

To assess the clinical effectiveness and safety of Bexagliflozin and Cagglitazone (Cagelin) in the management of type 2 diabetes, we conducted a study involving three hundred type 2 diabetes patients admitted to the hospital from May 2022 to May 2023. The patients were randomly allocated into two study groups. The Bexagliflozin treatment group consisted of 150 patients, while the control group included 150 patients who were administered Cagelin. During a 4-month intervention period, both cohorts were subjected to a rigorous evaluation. We conducted a comprehensive analysis encompassing their demographic data, glycemic fluctuations, pre- and post-treatment body weight variations, as well as vigilantly monitored for any potential adverse events. The results indicate a significant decrease in FPG, 2HPG, HbA1c, and body weight indicators in both groups after drug treatment. Notably, the Bexagliflozin group demonstrated a significantly greater reduction in blood glucose and body weight indices compared to the control group. The incidence of severe adverse reactions was slightly higher in the Bexagliflozin group at 7.33% compared to 6.67% in the control group, but this difference was not statistically significant (P>0.05). When compared to other SGLT2 inhibitors, Bexagliflozin demonstrates a more pronounced effect in regulating blood sugar levels and inhibiting weight gain in the treatment of type 2 diabetes.
GLOBAL DIGITAL DEATH AND GLOCAL DYING: THEORETICAL CHALLENGES AND POSSIBLE RESEARCH DIRECTIONS
Authors: TOPLEAN ADELA
Published: January 2024

This paper discusses the possibilities of using theories of glocalisation for understanding national differences in death ways, in times when global digital technologies play a growing role in how individuals and societies respond to severe crises. How people approach death is influenced by personal needs and values, unfolding within a thick framework of significance. Romania is a revealing example: what it is locally relevant is not unproblematically linked to a global pattern. After exploring the literature, we identify and discuss three key-directions of research that may be of help in further debates: 1. glocalisation of lived death practices and meanings; 2. glocalisation of death studies agendas; 3. the theoretical relevance of glocalism for understanding fundamental human experiences (we suggest a social phenomenological approach).

Published: January 2024

India has been a significant source of human resources for many countries. However, it has also emerged as a destination for migrants from the African continent and neighboring Asian countries like Bangladesh, Nepal, Sri Lanka, and Myanmar, seeking education and work opportunities. However, this influx of migrants and immigrants has led to various social problems and political challenges that require urgent policy attention. Within the host country, immigrants often face unfavorable conditions, uncertainty, and instability. The social problems resulting from migration and immigration in India encompass poverty, acculturation, education, housing, employment, social adjustment, and family difficulties. These challenges demand a comprehensive understanding and effective policy measures. In addition to the social issues, immigration and migration have significant political consequences. Questions arise regarding political inclusion, political liberties, effects on political stability, and potential implications for conflicts and wars. It is essential to address these political aspects to ensure a harmonious and sustainable social and political environment. This paper delves into a thorough analysis of the social problems and political challenges arising from immigration and migration within India. It takes into account both international immigration and internal migration, providing a holistic perspective on the issue. To tackle the identified social problems and political challenges, this paper proposes policy statements that prioritize the interests of all stakeholders involved, including the host country, the country of origin, local communities, and the immigrants and migrants themselves. The aim is to foster an inclusive and cooperative approach towards addressing these issues effectively.

Authors: KHAN A
Published: January 2024

This study was carried out to explore the percutaneous pinning versus open reduction K wire fixation in Gartland Type III supracondylar humerus fractures in children. This randomized control trial was conducted at the Department of Orthopaedic and Trauma DHQ Hospital Timergara Lower Dir KPK Pakistan hospital from September 2022 to November 2023. Eighty-four patients participated in this study, which was distributed into two groups. The open reduction and percutaneous pinning groups contained 42 patients each. Both groups were assessed for enhancement in function and radio-logically for fracture union. Children of both genders with Gartland type III supracondylar fractures between the ages of 2 and 12 years were included. In contrast, all children with open fractures, multiple fractures, and systemic diseases like infections such as pneumonia and individuals with cancer were excluded. In the group receiving percutaneous pinning, 33 (78.5%) children had excellent functional outcomes, 7 (16.6%) showed good functional outcomes, and 2 (4.7%) showed fair functional outcomes. In the open reduction group, there were 27 (64.3%) children with excellent functional results, 10 (23.8%) with good functional outcomes, 3 (7.1%) with fair outcomes, and 2 (4.7%) with poor functional consequences (p > 0.05). When treating children with Gartland type III supracondylar fractures of the humerus, percutaneous pinning is the safest and most successful method than open reduction with K wire fixation. Its apparent operative scars and other consequences are modest.

Published: January 2024

The Medan City Sanitary and Parks Department has the responsibility of carrying out the waste transportation process from the source of waste to the location of the Sanitary Landfill. Every day, the waste transportation vehicle receives a Road Order Letter from the sub-agency located in the sub-district, which contains information on waste transportation information. After the transportation is complete, the letter is submitted to the landfill scale department for tonnage and origin data collection. However, at present, all waste transportation data collection activities are carried out manually, including the provision of assignment letters and data collection of waste tonnage and fleet routes at the landfill. This results in ineffectiveness in the data collection operations. This encourages researchers to design a monitoring and fleet assignment information system at the Medan City Sanitary and Parks Service. Data collection is done by observation and interviews. The system development model in this system uses SDLC (System Development Life Cycle) Waterfall and uses UML (Unified Modeling Language) as a method of describing the flow of the system by applying the Use Case Diagram, Activity Diagram and Sequence Diagram models. The system is designed to run on a website system and is built using the PHP programming language with MySQL as a database. With this system, it is hoped that it can help in facilitating fleet assignments and monitoring the amount of waste entering the Sanitary Landfill .

Published: January 2024

The problem of contact interaction of two identical stringers with an elastic wedge of arbitrary angle of solution, when a system of cracks is located on the bisector of the wedge, is considered under conditions of antiplane deformation. The stringers are symmetrically bisected to the faces of the wedge. Stringers and crack banks are loaded with tangential forces causing antiplane deformation (longitudinal shear) of the wedge. Using the Mellin integral transformation, the solution of the problem is reduced to a system of two singular integral equations (SIE), from which the tangential contact stresses under the stringers and the dislocation densities at the crack banks are determined. The determining system of the SIE is solved by the numerical-analytical method of mechanical quadratures. A numerical analysis was carried out in the case where there is only one crack on the bisector of the wedge. Graphs were constructed illustrating the dependence of the main required quantities on the wedge opening angle and the distance between the wedge tip and the crack.

The research model was developed based on the Unified Theory of Accepting and Using Technology. In determining the causes and consequences of the attitudes, actions, ideas, and beliefs of the nurses, the screening technique of causal comparison was used. Research data was collected from registered nurses who work in research hospitals and use intelligent health technologies for inpatients. Based on 494 responses, this study conducted a dual-phase assessment using Partial Least Squares Structural Equation Modeling as well as the creation of an AI method known as deep learning (artificial neural network). According to the results, nurses are convinced that AI is a suitable tool for their nursing tasks and increases their efficiency and productivity. It has been determined that nurses have intentions to use AI nurses for outpatients with chronic diseases. However, nurses have concerns about the reliability of ambulatory patient data. The policies and strategies of regulators will affect the acceptance of AI technology, not only for nurses but for all healthcare professionals and patients.

Aim: The use of online learning, which has spread rapidly worldwide in recent years, has increased considerably with the COVID-19 pandemic. The study aimed to evaluate the online learning experience of children attending primary school 1st grade and the relationship between online learning, related factors, and Emotional/Behavioral problems.
Materials and Methods: This study was carried out with 378 mothers who have a child attending primary school 1st grade. Demographic data were assessed with the Sociodemographic Data Form, which included information about the online learning process and school, and the parent-rated Strengths and Difficulties Questionnaire (SDQ) to assess emotional/behavioral problems.
Results: 50.5% of the mothers reported that their children experienced emotional/behavioral problems, while 45.3% reported that online learning exacerbated their children's emotional/behavioral problems. SDQ Emotional problems score was significantly higher in girls, while SDQ Conduct problems and Hyperactivity/inattention subscores, and SDQ total scores were significantly higher in boys. The SDQ peer problems subscore and SDQ total scores of illiterates were significantly higher than those of literates. There was a significant negative correlation between the extracurricular screen time and all SDQ scores except the prosocial behavior subscore. The SDQ conduct problems and peer problems subscores and SDQ total scores of children with regular activities/hobbies were significantly lower than the others, while the SDQ prosocial behavior score was significantly higher.
Conclusion: Our study findings showed that online learning negatively affected almost half of the children in terms of emotional/behavioral problems for different reasons, gender can lead to differences in emotional/behavioral problems in early childhood, illiterate children and children with increased extracurricular screen time may be more at risk in terms of emotional/behavioral problems and regular activities/hobbies may contribute positively to the process.

Aim: We aimed to investigate the relationship between anxiety level, childhood trauma and psychological flexibility in patients with Generalize Anxiety Disorder (GAD).
Materials and Methods: This cross-sectional study was conducted with 100 outpatients diagnosed with generalized anxiety disorder between June 2022 and September 2022. Assessment tools were Childhood Trauma Questionnaire (CTQ), Psychological Flexibility Scale (PFS), Beck Anxiety Inventory (BAI).
Results: 62% of the participants were women in this study. their average age was 36.29 ± 13.21. The regression coefficient (correlation) between CTQ and BAI is not statistically significant (p>0.05). There was a negative relationship between CTQ and PFS (r = -0.213). It was determined that when CTQ increased by one unit, the PFS value would change by β=-0.215 units. There was a negative, relationship (r = -0.372) between PFS and BAI. It was found that when PFS increases by one unit, the BAI value will change by β=-0.240 units.
Conclusion: Although childhood traumas are not associated with anxiety severity in GAD patients, they may have a negative impact on psychological resilience. As psychological flexibility increases, anxiety severity decrease.

Published: January 2024

Objective: This study investigates impacts of the COVID-19 pandemic on psychiatric emergency department admissions in province of Trabzon.
Materials and Methods: The analysis involved examining changes in patient demographics, psychiatric diagnoses, and overall admission numbers during the pandemic compared to the previous year. The study focuses on patients aged over 16, utilizing records from three major healthcare centers in Trabzon province. Data including psychiatric diagnoses from the periods of March 11 to June 1 in both 2019 and 2020 are examined. Psychiatric diagnoses are categorized according to the International Classification of Diseases (ICD-10) classification system.
Results: The findings indicate a substantial (32.5%) decrease in psychiatric emergency department admissions during the pandemic. This reduction is observed across all three hospitals, with the most significant decline occurring in the hospital designated for pandemic cases. Both men and women showed decreased presentations, and there is a statistically significant increase in the median age of patients. While overall psychiatric diagnoses decreased, the proportions of specific diagnoses including anxiety disorder, schizophrenia, depressive disorder, and substance dependence, shoved increase during the study period.
Conclusion: Contrary to expectations, the study reveals a noteworthy decline in psychiatric emergency department admissions amid the COVID-19 pandemic. Similar trends are reported internationally. The discussion highlights potential factors contributing to this decrease, such as fear of COVID-19 transmission in hospitals, the perception that hospitals prioritize COVID-19 cases, and the availability of alternative mental health services. Concerns are raised regarding the long-term psychological impact of the pandemic, emphasizing the need for ongoing research and identification of high-risk groups not accessing emergency clinics during this period. The study acknowledges limitations, including reliance on hospital records and the potential for misdiagnoses in emergency settings, urging cautious interpretation of the results.

Authors: Payas Ahmet , n Sabri
Published: January 2024

Aim: The paranasal sinuses play a role in maintaining postural balance and synthesizing neurotransmitters such as nitric oxide (NO). Although the etiopathogenesis of idiopathic scoliosis (IS) is not fully known, it is known that hormonal and neurosensory mechanisms play a role. In this study, the possible effects of paranasal sinuses on the etiology of IS were investigated.
Methods: In this cross-sectional planned study, 38 individuals with IS (28 women and 10 men) and 39 healthy individuals (28 women and 11 men) were included. The right and left maxillary, sphenoid and frontal-ethmoid sinus volumes of the groups were calculated from magnetic resonance images. In addition, the entire head volume of each participant was calculated and the volume ratios occupied by all paranasal sinuses were calculated.
Results: In the IS group, the right maxillary sinus mean volume decreased by 16% and the left maxillary sinus volume value decreased by 14% compared to the control group (p<0.01). No significant difference was detected between the groups in the sphenoid and frontal-ethmoid sinus parameters (p>0.05). It was observed that the values of left maxillary sinus volume, frontal-ethmoid sinus volume, right maxillary sinus ratio, left maxillary sinus ratio and frontal-ethmoid sinus ratio were lower in male individuals in the IS group than in healthy individuals (p < 0.01).
Conclusion: In the presented study, it appears that the paranasal sinuses may have a role in the development of IS.
