Authors: Kim Jian , Park Jeongju
Published: March 2023

The purpose of this study was to develop and validate qualitative value indicators of region-based community dance for cultural urban regeneration. To this end, the conceptual structure of local-based community dance was explored and evaluation indicators were developed by deriving questions related to this. The specific research procedures and results are as follows: First, a literature review and Delphi survey were conducted to obtain factors and questions regarding qualitative value indicators. Consequently, four factors of local singularity, convergent creativity, sustainability, and community culture were obtained with 43 questions. Next, a preliminary survey targeting 122 people who have participated in representative local dance festivals (the ‘Wonju Dynamic Dancing Carnival’, ‘Cheonan World Dance Festival’, and ‘Andong Maskdance Festival’) in Korea was conducted to determine the relationship between the factors and questions. Multi-dimensional value indicators with 30 questions in four factors were obtained from an exploratory factor analysis using SPSS version 25.0. Then, the main survey, targeting 341 people who have participated in three representative local dance festivals in Korea, was conducted to verify the validity of the value indicators. Finally, evaluation indicators of 26 questions (seven questions for regional uniqueness, five questions for convergent creativity, seven questions for sustainability, and seven questions for community culture) were developed from a confirmatory factor analysis using AMOS version 24.0. Additionally, the contents evaluated by each factor are as follows: Firstly, ‘Local Singularity’ is a factor in whether the evaluation target sufficiently contains the unique characteristics of the region. Secondly, ‘Convergent Creativity’ is a factor in whether the evaluation target converges the indigenous culture (traditional culture) and acceptance culture (modern culture) of the region well. Thirdly, ‘Sustainability’ is a factor in whether the evaluation target contributes to the sustainable development of the region. Fourthly, ‘Community Culture’ is a factor in whether the evaluation target contributes to the formation of community culture in the region. This study is significant in that it emphasises the potential possibility of community dance, which can contribute to cultural urban regeneration based on the perspectives of cultural democracy. Therefore, the results of this study are expected to be extended and applied to various types of community dance in the future. Moreover, it is further forecasted that this study will suggest the meaning of the qualitative valuation of art and culture for a variety of subjects, such as policy experts and administrators, as well as for directors, choreographers, and participants in community dance.

Authors: Jiang Wei , Wang Yadong
Published: March 2023

Human health capital is an important factor that affects countries’ economic development. This research explores the nonlinear effect of human health capital on economic growth and assesses the asymmetry over time. We used annual data from 1978 to 2021 in China and the nonlinear autoregressive distributed lag (NARDL) model to examine the long- and short-term effects of positive and negative human health capital shocks on economic growth. Human health capital is measured by personal health expenditure (PHE), government health expenditure (GHE), and social service expenditure (SSE). A reduction of one unit in short-term private health expenditure leads to a 7.48% decrease in GDP per capita. An increase in private health expenditure leads to an increase in GDP per capita of 3.51%. The positive (βPHE+) and negative (βPHE−) coefficients of change in long-term private health expenditure are 1.31 and 3.87, respectively. A reduction in short-term government expenditure on health leads to a 10.99% decline in GDP per capita. The positive (βGHE+) and negative (βGHE−) coefficients of long-term government health expenditure are −4.33 and 1.99, respectively. A one-unit reduction in short-term social service spending leads to a 5.56 percent drop in GDP per capita, while an increase in social service expenditure leads to a 5.97 percent increase in GDP per capita. The positive (βSSE+) and negative (βSSE−) coefficients of change in long-term social service expenditure are 5.76 and 4.62, respectively. Both private health expenditure and government health expenditure have shown significant asymmetry in their long- and short-term effects on economic growth. Human health capital that is rationally distributed can effectively enhance economic growth.

Published: March 2023

Healthcare supply chains are complex systems facing challenges in delivering high-quality care while maintaining cost-effectiveness. Research on inventory management and control, the heart of the healthcare supply system, has demonstrated that these targets can be reached by managing inventories efficiently while aiming at desired service levels. Although this can be enabled by adopting various supply chain management practices, the healthcare sector appears to lag compared to other industries. Seeking to investigate these aspects, this study draws on operations management literature, identifies and categorizes technology-driven supply chain management practices that are applied in hospital operations, develops a holistic conceptual framework delineating the key factors influencing their adoption in healthcare facilities, and examines their aggregated impact on financial performance. The research model is tested using structural equation modeling with survey data collected from Greek public hospitals. The study results indicate that technological readiness, organizational readiness, perceived benefits, and hospital size significantly influence the adoption of these practices in hospital supply chains. Moreover, they show a statistically significant association between the supply chain management practices applied and improved hospital cost performance, suggesting greater urgency for hospitals to exploit them fully. Theoretical and practical implications of the findings are discussed.
Research on the Spatial Spillover Effect of Transportation Infrastructure on Urban Resilience in Three Major Urban Agglomerations in China
Authors: Wang Jian , Deng Yuzhou , Kumari Sonia , Song Zhihui
Published: March 2023

The development of transportation infrastructure can ensure the strong recovery and reconstruction function of a city, and it is an important way to build a resilient city. Studying the impact of the transportation infrastructure level on urban resilience is related to the future development of a city. Based on panel data for China’s three major urban agglomerations from 2008 to 2019, this paper uses the spatial econometric model to explore the spatial spillover effect of transportation infrastructure on urban resilience. The results show that, due to its spillover effect, intra-regional transportation infrastructure promotes the urban resilience of cities around Beijing–Tianjin–Hebei and the Pearl River Delta, while it only promotes the urban resilience of local cities in the Yangtze River Delta. Inter-regional transportation infrastructure not only inhibits the local urban resilience of Beijing–Tianjin–Hebei but also reduces the urban resilience of surrounding cities. However, the impact on the Yangtze River Delta and the Pearl River Delta is not obvious. To promote the overall resilience level in three major urban agglomerations in China, this paper argues that it is urgently required to improve the quality of urban road traffic facilities and optimize the structure of intercity transportation to promote the development of transportation infrastructure and urban resilience. The implementation of several policies is recommended to efficiently improve the transportation infrastructure and urban resilience in these three major urban agglomerations in China.
Digital Technologies and Sustainability Assessment: A Critical Review on the Integration Methods between BIM and LEED
Authors: Cascone Stefano
Published: March 2023

In the context of sustainable development and parametric design, it is interesting to analyze the possible synergies between Leadership in Energy and Environmental Design (LEED), the most-used certification scheme for the design, construction, and management of green buildings, and Building Information Modeling (BIM), which supports the supply, integration, and management of information throughout the building life cycle. This paper aims to review the state of the art of the different integration methods between LEED and BIM at the early design phase. Third-party software information exchange, the cloud-BIM approach, and plug-in development using application program interface (API) were considered as possible integration strategies to automate LEED certification by BIM. In addition, optimization models and rule-based methods were analyzed. Finally, a critical review on the limitations, advantages and future research developments in LEED and BIM integration was clearly defined. Although the development of plug-ins was the most powerful integration method, it requires advanced informatics knowledge. On the other hand, using third-party tools increased manual working and checking due to interoperability issues. A visual programming language (VPL) can allow designers and researchers without any informatics knowledge to create parametric BIM models by including LEED requirements.

Authors: Phan Huy N. Q. , Leu Jyh Hoang , Nguyen Vi N. D.
Published: March 2023

The world’s ever-growing population is driving an increased demand for clean water, which makes treating and reusing wastewater an essential practice. In recent years, biological and physicochemical methods have been preferred for wastewater treatment, with combined systems proving particularly effective. In this study, the combination of anaerobic digestion (AD) and electro-oxidation (EO) was investigated as a process for removing chemical oxygen demand (COD) from actual beverage wastewater. The effect of hydraulic retention time (HRT) on AD, electrolysis time, sodium chloride (NaCl) dosage, initial pH, and electro-properties on EO was investigated. At optimum conditions, namely an HRT of 2 days for AD, NaCl concentration of 3 g L−1, 80 min of EO time, natural pH (7.45), and applied voltage of 20 V for EO, the removal efficiency for COD was an impressive 96.47%, with energy consumption and specific energy consumption calculating 177.33 kWh m−3 and 33.79 kWh kgCOD−1, respectively. The amount of by-product gases (CH4 and H2) were also meagerly determined in this study. The results confirm that combining the AD and EO methods is an effective COD removal solution that can benefit the industry, while also offering a sustainable solution to combat water scarcity and meet the growing demand for clean water.
Game-Based Solutions and the Plastic Problem: A Systematic Review
Authors: Vecchio Luca Piero , Greco Alexia Del
Published: March 2023

Plastic pollution is an urgent worldwide environmental issue affecting marine, freshwater and terrestrial ecosystems. Half of the global plastic production is dedicated to items only used once: the so-defined single-use plastic (SUP) items. Different strategies have been implemented to reduce SUP consumption. Game-based solutions are an emerging strategy to favour behaviour change. The present systematic review aims at providing a synthesis of the current evidence about the use of game-based solutions to encourage sustainable behaviours concerning plastic (i.e., consumption, avoidance, waste management, pollution). Relevant studies were identified via three databases: Scopus, ProQuest and Web of Science for qualifying papers published between 2015 and 2021. Twenty-two studies that employed or designed game-based interventions to address the plastic problem were included. Results suggest that there is still little research exploring the use of game-based solutions to address the plastic issue. The studies included in this review mostly aim at changing behaviours and raising awareness towards plastic pollution among the general public. Although findings suggest that game-based intervention can be promising in terms of engagement and motivation and increasing knowledge of the issue, there is still little research focused on proving actual behaviour change, especially over time and in different settings.
Localizing Sustainable Development Goal 13 on Climate Action to Build Local Resilience to Floods in the Hunter Valley: A Literature Review
Authors: Mortimer Anastasia , Ahmed Iftekhar , Johnson Thomas , Tang Liyaning , Alston Margaret
Published: March 2023

The realization of the 2030 Agenda for Sustainable Development requires local governments globally to integrate Sustainable Development Goals (SDGs) into their policy and practice. In the case of the Hunter Valley Region of Australia, a key sustainable development issue is climate change-induced flooding. The localization and mainstreaming of SDG 13 on climate action can support tangible municipal climate actions in the Region. However, while it is acknowledged that SDG localization is needed to address sustainable development challenges, there is a gap in research and practice to guide local government attempts at SDG localization. This research analyzes literature on SDG localization to understand strategies, challenges and gaps that can inform localization approaches for the Hunter Valley. An analysis of the literature revealed that the implementation of SDG 13 at the local government level is a sparsely researched area, and in practice, efforts to implement SDG 13 have not been publicly communicated. Research-based recommendations for SDG 13 localization are presented to highlight the potential of integrating SDGs into pre-existing local policy so that the SDGs and their targets can support climate action and decrease disaster risk of future floods in Hunter Valley communities.
The Impact of Sporting Events on Air Pollution: An Empirical Examination of National Football League Games
Authors: Watanabe Nicholas , Yan Grace , McLeod Christopher
Published: March 2023

(1) Background: Prior research has found that large-scale sporting events may potentially impose negative consequences on the environment, thus impeding the sustainability goals of the sport industry. Along these lines, the current study extends the literature by examining the impact that National Football League (NFL) games have on local-area air pollution. (2) Methods: Air Quality Index (AQI) data measuring six major forms of air pollution were gathered from air monitors positioned close to NFL stadiums and matched with the number of attendees at games. From this, multiple regression analysis was utilized to estimate whether the number of fans was related to changes in air pollution. (3) Results: The regression models found that Ozone and Nitrogen Dioxide levels increased as more individuals attended NFL games. Additional robustness checks and falsification tests suggest that the average NFL event results in an approximately two-percent increase in Ozone levels. (4) Conclusions: The findings from this study contribute to the literature by providing evidence that highly attended sporting events increase pollution levels in the areas near stadiums. Thus, governments and sport organizations should consider low-emission methods to get fans to travel to games in order to reduce their environmental impact.
Managing Sustainable Sharing Economy Platforms: A Stimulus–Organism–Response Based Structural Equation Modelling on an Emerging Market

Published: March 2023

Due to the rising appeal of travel, as well as the appearance of low-cost carriers that fly to both popular and exotic destinations, people nowadays tend to book their accommodation through the more convenient and flexible sharing economy platforms. The success of such platforms among consumers depends on various factors, such as satisfaction and platform credibility, and on sustainable performance among contributors, increasing their relevance and visibility. This research proposes a conceptual model for measuring the success of sharing economy platforms in tourism, based on added value, unique experience, and enhanced social interactions, together with credibility and sustainable performance. In this vein, the authors conduct an empirical investigation in an emerging market—Romania—where the development of such sharing economy platforms is still in its infancy. Data gathered by the authors by means of a self-developed questionnaire distributed to 500 respondents are modelled via structural equations with SmartPLS. The results indicate that the platform credibility and sustainable performance of sharing economy platforms are key elements in generating their success. The research adds value to the stimulus–organism–response approach, highlighting some insights from a relevant emerging market, which in the future could become a turning point for inbound and outbound tourism.

Published: March 2023

Cost estimates in the early stages of project development are essential for making the right decisions, but they are a huge challenge and risk for owners and potential contractors due to limited information about the characteristics of a future highway project. Whereas previous studies were mainly focused on achieving the highest possible estimation accuracy, this paper aims to propose cost-estimation models that can provide satisfactory accuracy with the least possible effort and to compare the perspectives of owners and contractors as the key stakeholders on projects. To determine cost drivers (CDs) that have a high influence on highway-construction costs and require low effort for their establishment, a questionnaire survey was conducted. Based on the key stakeholders’ perceptions and collected data set, cost-estimation models were developed using multiple-regression analysis, artificial neural networks, and XGBoost. The results show that reasonable cost-estimation accuracy can be achieved with relatively low effort for three CDs for the owners’ perspective and five CDs for the contractors’ perspective. Additional inclusion of input CDs in models does not necessarily imply an increase in accuracy. Also, the questionnaire results show that owners are more concerned about environmental issues, whereas contractors are more concerned about the possible changes in resource prices (especially after recent high increases caused by COVID-19 and the Russia–Ukraine war). These findings can help owners and potential contractors in intelligent decision-making in the early stages of future highway-construction projects.
Perspectives on Taiwan’s Pathway to Net-Zero Emissions
Authors: Chen Pin-Han , Lee Cheng-Han , Wu Jun-Yi , Chen Wei-Sheng
Published: March 2023

For achieving net-zero emissions by 2050, countries worldwide are committed to setting ambitious carbon reduction targets. In 2022, the officially published report, “Taiwan’s Pathway to Net-Zero Emissions in 2050”, sets out a comprehensive transition plan based on four fundamental strategies: energy, industrial, lifestyle, and social. This transition will likely entail an infrastructure transformation in all sectors of the economy, embracing renewable energy, electricity, and low-carbon fuels. While the Taiwan government is rolling up its sleeves to accelerate the pace of carbon-emission reduction, it is risky to set targets without considering the full implications of net-zero emission and how it will be achieved. This paper provides four insights into Taiwan’s net-zero-emission plan from a perspective of the current understanding of decarbonization and the techniques urgently needed. Although many uncertainties and outstanding questions exist in our net-zero energy systems, and the required granular information for decision makers to track progress has not been clearly identified, this paper points out the characteristics that have been neglected and provides guidance for all stakeholders—governments, businesses, investors, and citizens—to work together on a coordinated plan to tackle climate change.
Intelligent Damage Assessment for Post-Earthquake Buildings Using Computer Vision and Augmented Reality
Authors: Liu Zhansheng , Xue Jie , Wang Naiqiang , Bai Wenyan , Mo Yanchi
Published: March 2023

The most negative effects caused by earthquakes are the damage and collapse of buildings. Seismic building retrofitting and repair can effectively reduce the negative impact on post-earthquake buildings. The priority to repair the construction after being damaged by an earthquake is to perform an assessment of seismic buildings. The traditional damage assessment method is mainly based on visual inspection, which is highly subjective and has low efficiency. To improve the intelligence of damage assessments for post-earthquake buildings, this paper proposed an assessment method using CV (Computer Vision) and AR (Augmented Reality). Firstly, this paper proposed a fusion mechanism for the CV and AR of the assessment method. Secondly, the CNN (Convolutional Neural Network) algorithm and gray value theory are used to determine the damage information of post-earthquake buildings. Then, the damage assessment can be visually displayed according to the damage information. Finally, this paper used a damage assessment case of seismic-reinforced concrete frame beams to verify the feasibility and effectiveness of the proposed assessment method.

Published: March 2023

Sustainability is a critical issue for businesses today, and corporate boards and nomination committees play a vital role in promoting sustainable practices within organizations. Nomination Committees (NCs) have become important mechanisms for what has been coined as good or sustainable governance. Stakeholders, however, have different opinions on the merits of these committees. Amongst other things, there is disagreement about whom to select for NCs and the criteria for selection. The composition of NCs can influence board nominations and determine whether the necessary knowledge and skills reside within a board to deal with sustainability and good corporate governance. The aim of this research is to provide insights into stakeholders’ perspectives on what matters when profiling nomination committees’ members. The literature on NCs is underdeveloped, and this research importantly addresses the issue by interviewing 13 individuals who are either shareholders, board members of listed companies, or members of NCs. Additionally, a questionnaire was sent to shareholders, board members, and NC members of the 300 largest companies in Iceland. A total of 138 responses were received. The results show that stakeholders believe it is important to decide upon an NC’s composition prior to electing its members. NC members should have either management or board membership experience. Diversity within the committees is also seen to be important, as it can influence diversity and inclusion overall at the board level. These research results provide important insights and understanding for shareholders and boards of directors when composing nomination committees.

Published: March 2023

Growing expectations and interest in the metaverse have increased the need to explore the public hype. This study measured the hype in the South Korean metaverse context and analyzed its temporal pattern. To this end, 129,032 tweets from Korean users who used the “metaverse” keyword were collected, and 86,901 tweets were analyzed. Using BERT-based topic modeling, a content analysis was performed. The extracted topics were classified into three expectation frameworks: specific expectations, generalized expectations, and frames. Our results imply that the pre-emptive inflation of expectations by the Korean government caused the public’s excessive expectations of the metaverse. Additionally, by using Twitter as a source for analyzing user-perceived hype, it was confirmed that the public responds to the expectations of other actors about the technology rather than expecting the technology itself. Furthermore, pronounced hype dynamics were observed by analyzing the distribution of topics over time.
Future Health Risk Assessment of Exposure to PM2.5 in Different Age Groups of Children in Northern Thailand
Authors: Amnuaylojaroen Teerachai , Parasin Nichapa
Published: March 2023

Particulate matter with a diameter less than 2.5 (PM2.5) is one of the major threats posed by air pollution to human health. It penetrates the respiratory system, particularly the lungs. In northern Thailand, the PM2.5 concentrations have significantly increased in the past decade, becoming a major concern for the health of children. This study aimed to assess the health risk of PM2.5 in different age groups of children in northern Thailand between 2020 and 2029. Based on the PM2.5 data from the simulation of the Nested Regional Climate Model with Chemistry (NRCM-Chem), the hazard quotient (HQ) was used to estimate the possible risk from PM2.5 exposure in children. In general, all age groups of children in northern Thailand will tend to experience the threat of PM2.5 in the future. In the context of age-related development periods, infants are at a higher risk than other groups (toddlers, young children, school age and adolescents), but adolescents also have a lower risk of exposure to PM2.5, albeit maintaining a high HQ value (>1). Moreover, the analysis of risk assessment in different age groups of children revealed that PM2.5 exposure might indeed affect adolescent risk differently depending on gender, with males generally at a heightened risk than females in adolescence.

Published: March 2023

Antibiotic resistance genes can be spread via gene horizontal transfer (GHT). Chlorination and UV irradiation are common disinfection methods used in wastewater treatment plants before the discharge of treated wastewater. This study aimed to elucidate the effects of disinfection on the transformation of naked DNA in the aquatic environment. The pUC19 plasmid possessing ampicillin-resistant beta-lactamase and subjected to different dosages of chlorine or UV irradiation was used for transformation in Escherichia coli to estimate the transformation efficiency and GHT in the environment after disinfection. The results showed that doses > 0.5 mg-Cl2/L can effectively decrease transformation efficiency (1.21 to 8.83-log10) based on pUC19 as the positive control. UV irradiation can decrease the efficiency (2.37 to 3.39-log10) following 10–60 min of treatment. PCR and qPCR detection have limitations for determining transformation efficiency because they provide approximate estimates damaged DNAs. Overall, these results indicate that proper disinfection management using chlorine and/or UV for treated wastewater before discharge from wastewater treatment plants can prevent the spread of antibiotic resistant bacteria and genes, by decreasing the efficiency of naturally occurring bacterial transformations in wastewater treatment plants.

Authors: Li Cuicui , Wu Wenliang
Published: March 2023

Understanding the evolution characteristics and driving mechanisms of eutrophic lake ecosystems, especially over long time scales, remains a challenge. Little research on lake ecosystem mutation has been conducted using long-term time series data. In this study, long-term water quality indicators, as well as ecological indexes, natural meteorological factors, and socio-economic indexes, were collected for Tai Lake to enable us to study the environmental evolution of the lake ecosystem. The key time nodes and early warning signals of the steady-state transformation of Tai Lake were also identified, which could provide a theoretical basis for early indication of the transformation of lake ecosystems. Furthermore, the characteristics and driving mechanism of the lake’s ecosystem evolution were analyzed based on the physical and chemical indexes of its sediments and its long-term water quality indexes. The results show that the early warning signals (variance, autocorrelation, and skewness) of ecosystem mutation included abnormal changes 10 years before the steady-state change, and the evolution of Tai Lake was driven by the complex nonlinear effects of biological, physical, chemical, and socio-economic factors in the lake basin. These results have important theoretical and practical value for pollution control and the management of eutrophic lakes.

Published: March 2023

A strong positive image is an important asset for all countries around the world. Simple recognition of a name or geographic location is not enough to make a successful brand. People should want to visit, live, and preferably work and invest in the country. The research methodology for this article used Simon Anholt’s approach. Anholt is the author of the widely recognized system Nation Brands Index which measures the power and quality of each country’s “brand image” by combining the following six dimensions: Exports, Governance, Culture and Heritage, People, Tourism, and Investment and Immigration. In this article, the authors selected one important dimension, “Investment and Immigration,” using the case of the Astana International Finance Centre (AIFC), which was created to enhance and promote Kazakhstan’s investment image. The expected outcomes of the study include assessing the perception of how the AIFC used digital technologies to build its brand as a part of the country’s image, and discussing the digital context of developing investment attractiveness. It also covers a short literature review on the theoretical and empirical aspects of digital transformation and presents a case study and a questionnaire-based survey to illustrate the impact of digital transformation, and especially the use of digital technologies for the AIFC’s image promotion. The conclusion summarizes the findings of this research and discusses some implications for investment and immigration attractiveness and the image of the AIFC.

Published: March 2023

The state and strategic scenarios to recover the sustainable development of air transport in Ukraine in the post-war period are studied. Research is fulfilled with the scientific justification of quantitative indicators and macro-indicators of maintaining the trajectory of sustainable development in the medium-term perspective. The starting point of strategizing is the concept of sustainable development in the safety dimension as a management construct that contains a general systemic view of the ways to transfer from the current state of the management object to the desired one and includes the stages of identification and strategizing. Identification involves an integral convolution with dynamic weighting coefficients and a formalized justification of the limits of safe existence. A new methodology is used for strategizing, which, unlike classical forecasting methods (the past determines the future), uses the principle "the future is determined by the trajectory into the future" and is based on the method of adaptive regulation from the management theory. According to the defined methodology, three strategic recovery scenarios were developed with the annual rates of growth of real aviation transport: realistic – 4.5%; optimistic – 7.2% and the scenario of entering the optimal zone of the EU countries – 10.4%. The resulting dynamics of components, indicators and macro indicators is, in fact, a strategic plan for the post-war recovery of the economy and entering the path of sustainable development. Threats are identified and institutional measures are proposed for airlines and national systems of airports and airfields, air navigation services, aviation industry, aviation education and science of Ukraine. The strategic orientations of the environmentalization of air transport of Ukraine in the post-war period and the strategic priorities of the recovery of the air transport infrastructure were formulated, and the necessity to pursue a course towards carbon neutrality was proved.

Giriş
Hipogonadotropik hipogonadizm, gonadotropik hormonların farklı nedenlerle salınımındaki eksikliğe bağlı gelişen gonadal yetmezlik tablosudur ve önemli klinik sonuçlara yol açar. En önemli sebepleri arasında hipofizer hastalıklar yer almakta olup hipofize yönelik görüntüleme tanısal amaçlı önemli bir yere sahiptir. Biz bu çalışmada kliniğimizde son beş yılda takip edilen hipogonadotropik hipogonadizm tanılı erkek hastaların hipofiz MR (Manyetik Rezonans) görüntüleme sonuçlarını ve laboratuvar bulgularını inceledik.
Materyal ve Metod
2017-2021 yılları arasında endokrinoloji polikliniğimize başvuran ve hipofiz MR görüntüleme sonuçları hastane bilgi işlem sisteminde mevcut olan hipogonadotropik hipogonadizm tanılı 56 hasta retrospektif olarak incelendi. Hastaların yaşları, geliş şikayetleri, hipofiz MR görüntüleme bulguları ve hormon düzeyleri irdelendi. IBM SPSS Versiyon 22.0 programı kullanılarak verilerin istatistiksel analizi yapıldı.
Bulgular
Hastaların yaş ortalaması 37.75 ± 10.95 olarak saptandı. Hastaların başvuru şikayetleri incelendiğinde en sık libido kaybı %37.5 (n=21) olduğu görüldü. %42.9 hastanın (n=24) hipofiz MR’ının normal saptandığı görüldü. Hastalar MR bulgularına göre alt gruplara ayrılarak hormon değerleri analiz edildiğinde “Makroadenom” grubunda “Mikroadenom” grubuna göre ortalama total testosteron düzeyi anlamlı olarak daha düşük saptandı (p < 0.05).
Sonuç
Hipogonadotropik hipogonadizm tanılı hastalarda hipofize yönelik görüntüleme yapılmasının özellikle laboratuvar bulgularına göre endikasyonları net olmayıp bu konuda yapılacak geniş kapsamlı çok merkezli çalışmalara ihtiyaç bulunmaktadır.

Published: March 2023

Muitos são os fatores que contribuem para o surgimento e ressurgimento de enfermidades em uma população, dentre estes, pode-se citar a falta de informação dos indivíduos a respeito dos cuidados necessários para prevenção e controle das doenças. O presente trabalho possui o objetivo comparar o conhecimento da população residente dos cinco distritos sanitários do município de Foz do Iguaçu-PR a respeito da leptospirose, leishmaniose, raiva e toxoplasmose. Este tipo de informação pode servir de parâmetro para planejamentos de programas educacionais em saúde serem  direcionados às regiões mais necessitadas. Para isto, foram obtidas respostas de 260 indivíduos através de questionário online na plataforma Google Formsâ disponibilizados via WhatsAppâ e páginas específicas relacionadas aos bairros do município de Foz do Iguaçu pelo Facebookâ. Constatou-se que o distrito sanitário Sul do município possui informações insuficientes sobre a maioria das doenças trabalhadas no questionário, sendo percebida pouca sensibilidade das pessoas ao assunto objeto da pesquisa, fato que intensifica o desafio de trabalhar educação em saúde com esta população. Além disto, as doenças zoonóticas leptospirose e toxoplasmose são relativamente desconhecidas pela população entrevistada por este estudo, embora haja percepção da população de relativa atuação dos clínicos médicos veterinários como disseminadores de informações relevantes sobre doenças zoonóticas.

With the development of material synthesis technology, they can be functionalized and used in various fields such as energy, environment, and biomedicine. In particular, stimuli-responsive carbon-based nanomaterials have stood out in recent years because of their
smart
behavior. Researchers have applied carbon-based nanomaterials to different disease treatments based on their stimulus-response properties. In this paper, based on stimuli-responsive carbon-based nanomaterials’ morphology, we categorize them into carbon nanotubes, carbon nanospheres, and carbon nanofibers according to their morphology. Then, their applications in probes, bioimaging, tumor therapy, and other fields are discussed. Finally, we address the advantages and disadvantages of carbon-based stimuli-responsive nanomaterials and discuss their future perspective.

Water temperature is one of the most important factors that affect the occurrence of harmful algal blooms (HABs). Characteristics of sea surface temperature (SST) variability related to a
Noctiluca scintillans
bloom were analyzed with Himawari-8 data in the Beibu Gulf during mid-February 2021. An SST warming anomaly was found around the bloom area from 10:00 to 19:00 local time, with a peak temperature of 24.3 °C at 15:00, which was 2.9 °C higher than the surrounding normal sea water. The possible formation mechanism of the HAB-induced SST anomaly was studied in this work by integrating meteorological, ocean dynamics, and ecological processes. During the HAB event, the sea surface was covered by biological mucilage. A model that considered the net heat flux, heat capacity, density of seawater, and temperature variation was established to estimate the thickness changes (Δ
H
) in the marine heating layer during the HAB event. The model results show that the heating layer thickness of the HAB area (Δ
H
between 0.76 m and 0.91 m) was smaller than that of the non-HAB area (Δ
H
> 1.19 m). The SST anomaly in this study might be caused by a thinner and warmer marine heating layer that is related to the biological mucilage on the surface of the HAB area.
A Torsion-Bending Antagonistic Bistable Actuator Enables Untethered Crawling and Swimming of Miniature Robots

Miniature robots show great potential in exploring narrow and confined spaces to perform various tasks, but many applications are limited by the dependence of these robots on electrical or pneumatic tethers to power supplies outboard. Developing an onboard actuator that is small in size and powerful enough to carry all the components onboard is a major challenge to eliminate the need for a tether. Bistability can trigger a dramatic energy release during switching between the 2 stable states, thus providing a promising way to overcome the intrinsic limitation of insufficient power of small actuators. In this work, the antagonistic action between torsional deflection and bending deflection in a lamina emergent torsional joint is utilized to achieve bistability, yielding a buckling-free bistable design. The unique configuration of this bistable design enables integrating of a single bending electroactive artificial muscle in the structure to form a compact, self-switching bistable actuator. A low-voltage ionic polymer–metal composites artificial muscle is employed, yielding a bistable actuator capable of generating an instantaneous angular velocity exceeding 300 °/s by a 3.75-V voltage. Two untethered robotic demonstrations using the bistable actuator are presented, including a crawling robot (gross weight of 2.7 g, including actuator, battery, and on-board circuit) that can generate a maximum instantaneous velocity of 40 mm/s and a swimming robot equipped with a pair of origami-inspired paddles that swims breaststroke. The low-voltage bistable actuator shows potential for achieving autonomous motion of various fully untethered miniature robots.
Моделювання, CFD-розрахунок та оцінка гідродинамічних коефіцієнтів ав-тономного безпілотного підводного апарата

Published: March 2023

Дослідження, розробка і створення систем орієнтації, навігації та керування автономними безпілотними підводними апаратами (АБПА) — складна і трудомістка задача морської робототехніки. Для створення таких систем потрібні знання та розуміння умов функціонування апарата та його конструкції, а також реакції конструкції апарата на зовнішні чинники. Для виявлення та урахування всіх факторів необхідно знати геометричні та гідродинамічні характеристики апарата. Мета дослідження — обґрунтувати вибір торпедоподібної форми АБПА, що відноситься до класу мініапаратів масою від 20 до 100 кг, проаналізувати вплив торпедоподібної конструкції АБПА на характеристики обтікання та визначити його гідродинамічні коефіцієнти при різних швидкостях руху та кутах нахилу (диференту). Підготовка і моделювання конструкції та гідродинамічний аналіз АБПА виконувалися в програмних пакетах «Solidworks» та «ANSYS Workbench» (пакет «Fluen» відповідно). Дослідження проводилися в імітованому водному прісному просторі. В результаті розрахунків отримано значення сил, які виникають при різних швидкостях та кутах нахилу. На основі отриманих значень сил вирахувано значення гідродинамічних коефіцієнтів, які було зведено до таблиць, та побудовано відповідні графіки. Обґрунтовано вибір торпедоподібної форми АБПА. Визначено сили та гідродинамічні коефіцієнти під час руху апарата, які необхідно використовувати при дослідженні та розробці системи автоматичного керування. При різних швидкостях та кутах нахилу гідродинамічні коефіцієнти мають кореляцію один із одним, що дає змогу їх усереднити і апроксимувати до певної залежності, якою можна користуватися у подальших дослідженнях.
Оптимальне керування початковою умовою для дробового за часом хвильового рівняння
Authors: Веклич Ростислав Анатолійович , Семенов Володимир Вікторович
Published: March 2023

Розподілені системи з дробовими похідними використовуються при математичному моделюванні процесів поширення механічних хвиль у в’язкопружних матеріалах, аномальної дифузії в неоднорідних середовищах, наприклад внутрішньоклітинного руху часток в цитоплазмі клітин, та розповсюдження забруднення у пористих водоносних шарах ґрунту. Такий процес дифузії відбувається, зокрема, тоді, коли окремі частинки, що рухаються, можуть на тривалий час затримуватись (наприклад, в ґрунтових порах чи через часті зіткнення з іншими елементами неоднорідного середовища). Для ґрунтовно досліджених систем, поведінка яких описується гіперболічними рівняннями зі звичайними похідними цілих порядків, раніше було отримано результати існування та єдиності для розв’язку як рівняння стану системи, так і задач керування різних типів з різноманітними функціоналами якості. Доцільно також розглянути аналогічні задачі керування для згаданих рівнянь з похідними дробових порядків, спробувати довести існування та єдиність розв’язку і навести умови його оптимальності. У даній роботі розглянуто однорідне дробове хвильове рівняння стану системи (або дробово-гіперболічне, або  рівняння супердифузії) з лівосторонньою похідною Капуто за часом порядку від 1 до 2 та звичайними похідними цілих порядків за просторовими змінними. Для рівняння стану задано умови для розв’язку та його першої похідної (цілого порядку) в початковий момент часу і розглядається задача керування цією похідною першого порядку з квадратичним компромісним функціоналом якості. Для хвильового рівняння, яке описує стан системи, в роботі отримано нові додаткові оцінки регулярності розв’язків. Аналогічні оцінки отримано і для спряженого до вихідного рівняння, яке містить правосторонню дробову похідну Рімана–Ліувілля за часовою змінною. Доведено також теорему існування та єдиності розв’язку задачі оптимального керування. Сформульовано й обґрунтовано необхідні та достатні умови оптимальності як для випадку, коли область допустимих керувань обмежена, так і для випадку, коли обмеження на керування відсутні.
