Background: The adequate preload was the goal of hemodynamic optimization for sepsis resuscitation. The fluid strategy in the early phase of sepsis is unclear.

Objective: To investigate the efficacy of a fluid bolus to prevent new-onset hypotension in suspected sepsis patients with hyperlactatemia (Point-of-care serum lactate 2-4 mmol/L).

Methods: The Fluid Bolus in Suspected Sepsis Patients with Hyperlactatemia Trial (FISH) is a single-center, open-label randomized controlled trial. Participants will be patients suspected of having sepsis with hyperlactatemia (Point-of-care serum lactate 2-4 mmol/L) in the emergency department of Srinagarind Hospital, Thailand. Eligible patients will be randomized (1:1) to one of the study arms using block randomization. They will be placed in either the fluid bolus group (intervention, 30 mL/kg within 3 hours) or the standard care group (control). The primary outcome is new-onset hypotension within 24 hours after randomization. Secondary outcomes include lactate clearance, ∆SOFA at 72-hours, organ failure, and support ‘free days’ to day 28, 28-day mortality.

Hypothesis: We hypothesize that a fluid bolus will prevent new-onset hypotension in suspected sepsis patients with hyperlactatemia (point-of-care serum lactate 2-4 mmol/L).

Discussion: The optimal strategy for intravenous fluid therapy in a patient suspected of sepsis with hyperlactatemia is unknown. This is the first randomized trial examining fluid strategy in the early phase of sepsis with mild hyperlactatemia.

A Study on Audit Failures by Certified Public Accounting Firms
Authors: Ge Junwen
Published: August 2024

Audit failure occurs when certified public accountants (CPAs) fail to disclose significant misstatement risks in the audit report. Such failures frequently lead to various degrees of social harm. Therefore, it is crucial to investigate the causes of audit failures to address these issues fundamentally and prevent their occurrence from different angles. This paper examines audit failures from four perspectives: chaotic audit pricing, inadequate audit preparation, substandard CPA audit competence, and insufficient supervision of auditors. It proposes specific methods to reduce audit failures, including optimizing pricing, enhancing pre-audit preparations, refining audit procedures, and improving audit supervision.
The Impact of Geopolitical Conflict and Fed Rate Hikes on Asset Pricing
Authors: Ge Zihan
Published: August 2024

In the current context of weak economic recovery, ongoing Russia-Ukraine conflict, and consecutive interest rate hikes by the Federal Reserve, global financial and commodity markets have experienced intensified turbulence. To investigate the impact of the Russia-Ukraine conflict and the Federal Reserve interest rate hikes on asset pricing, this study first analyzed the U.S. stock market, bond market, and commodity market based on data from the CEIC database. From the comprehensive stock and year-on-year data after each round of interest rate hikes, it is evident that both the Russia-Ukraine conflict and the Federal Reserve interest rate hikes have had a significant negative impact on investors' financial assets. Additionally, due to the continuous interest rate hikes by the Federal Reserve, funds from the stock market have gradually shifted to the bond market. Furthermore, after analyzing the impact of the Russia-Ukraine conflict and the Federal Reserve interest rate hikes on the U.S. stock market, bond market, and commodity market, the study further explored the influence of these factors on asset pricing using the discounted cash flow (DCF) valuation model. Finally, the study provided an outlook on future market trends.
Why is KOL (Key Opinion Leader) Advertising on Social Media more Effective at Attracting Consumers than Official Brand Accounts?-Exploring Lancmes Promotion on Chinese Platform RED
Authors: Kong Ximing , Wu Henry
Published: August 2024

In the context of the flourishing digital market, effectively utilizing social media for advertising has become one of the primary concerns for brands. This article aims to investigate the reasons why advertising campaigns by KOLs (Key Opinion Leaders) on Chinese social media platforms garner more attention from consumers compared to official brand accounts. This research employs a case study and interview methodology. The first set of data presents the advertising content and responses of both Lancme's official account and KOL accounts on the Chinese social media platform, Xiaohongshu (RED). The second set of data showcases the interview results from five recruited participants on RED. Each participant was asked to assess their attitudes towards different forms of product promotion. The results indicate that KOLs' posts on RED offer a more relatable and curiosity-inducing perspective by sharing product experiences in everyday life scenarios. This approach resonates with users and brings the promotion closer to consumers. In contrast, the content strategy of official brand accounts tends to focus more on product features, which increases the perceived distance from consumers. Furthermore, interaction data and user feedback from KOL accounts reveal that users are more inclined to trust and reference the authentic usage experiences of fellow consumers rather than official product descriptions. These findings elucidate the practical impact of official brand accounts versus KOL accounts in social media advertising, highlighting the unique value of KOL advertising. Our research is poised to inspire brands to reconsider their social media advertising strategies, potentially bringing forth greater appeal and competitive advantage for the brands.

Application of Business Intelligence Technology Model to Sustainable Supply Chain
Authors: Shi Xinyan
Published: August 2024

Under the backdrop of globalization, sustainable supply chains are becoming one of the most important directions for commercial development in the future. The efficiency of supply chain management (SCM) will be significantly improved when business intelligence is used in the supply chain. Sustainable supply chain refers to the integration of sustainable development elements on the basis of traditional supply chain management, introducing the assessment and management of social, environmental, economic benefits and other risks. The aim of this paper is to look at how different BI techniques affect different business models. Most of this paper is a summary of previous scholars work. The most successful and widespread application of BI is the final outcome of the technology acceptance model. These three BI models have different effects on sustainable supply chains, but in general, BI is very helpful for sustainable supply chain development in all aspects. Future results would be much more accurate and effective if three techniques were actually able to monitor and compare the sustainability of supply chains.

A criopreservação do sêmen bovino contribui para as cadeias produtivas do leite e da carne, melhorando a eficiência dos rebanhos e, consequentemente, sua lucratividade. Neste contexto, diferentes métodos e aditivos são utilizados para melhorar a resistência espermática à criopreservação. O objetivo deste trabalho foi avaliar o uso de ácido ascórbico (vitamina C) e Trolox (vitamina E sintética) como antioxidantes no meio diluidor de sêmen para preservar a viabilidade do sêmen no processo de congelamento-descongelamento. Oito touros, cinco Bos taurus indicus e três Bos taurus taurus, foram selecionados e submetidos a três coletas de sêmen em intervalos de 48 horas. Os ejaculados foram submetidos a uma análise prévia de motilidade, vigor e concentração, a seguir colocados em palhetas de 0,25 mL na proporção de 25×106 de espermatozoides viáveis, e distribuídos em quatro grupos: GI (sêmen diluído sem adição de vitaminas), GII (sêmen diluído com 250 μmoL mL-1 de Trolox), GIII (sêmen diluído com 0,60 mg mL-1 de vitamina C) e GIV (sêmen diluído com 0,60 mg mL-1 de vitamina C + 250 μmoL mL-1 de Trolox); posteriormente, foram submetidos à criopreservação. Os movimentos e a cinética dos espermatozoides descongelados foram analisados por Computer-Assisted Semen Analysis (CASA), não havendo diferença (p<0,05) entre os tratamentos. A avaliação da viabilidade espermática por citometria de fluxo e peroxidação lipídica por Substâncias Reativas ao Ácido Tiobarbitúrico (TBARS) também não mostrou diferenças (p<0,05) entre os antioxidantes utilizados no sêmen diluído. O sêmen do grupo GIV apresentou 35,08% de motilidade, avaliada pelo Teste de Resistência Térmica (TRT); e 49,41% de integridade da membrana plasmática, quantificada pelo Teste de Inchaço Hiposmótico (HOST). Esses valores foram superiores (p<0,05) aos encontrados para o sêmen dos grupos GI (29,83% e 42%), GII (30,66% e 43,85%) e GIII (32,41% e 46,68%) que não apresentaram diferenças entre si (p>0,05). A interação entre Trolox e vitamina C gerou resultados significativos para a motilidade espermática após o descongelamento quando avaliada pelo TRT, e a viabilidade espermática quando avaliada pelo HOST, sendo superiores aos encontrados no grupo controle e no grupo com adição de vitamina C.

Ports are some of the most significant entry points for Greek tourism investments and can be characterized as “development tools” for the country, both at the local and national level. The blue economy is a recent example of economic development, globally promoted as a way to achieve sustainability in maritime and coastal areas. Linaria Port has been accredited by the United Nations as “the blue port with a shade of green”, constituting an environmentally sustainable community capable of promoting responsible environmental behavior both within the local community and among tourists. The port has been highly competitive in achieving high sustainability standards and mainly operates in ways that complement environmental quality. It has presented innovative, competitive, and sustainable solutions since 2010. This research aimed to collect primary and secondary data on tourist preferences to evaluate these services. Evaluation was conducted through anonymous questionnaires divided into two parts: the first part concerned the tourist profile, and the second part concerned tourists’ opinions on the services and facilities of the port and the island. In the evaluation of the port, 91% of respondents rated the marina positively compared to other ports in the country, while 77% ranked the port of Skyros in a good position compared to other European or international ports. The overall quality of the tourist product was positively evaluated at 89%, while 90% of visitors were generally satisfied with the overall services offered.

A Systematic Review on Impact of Political Crisis and Election on Capital Market Returns
Authors: Sarkar Popy Rani , Roy Gourav
Published: August 2024

The capital markets worldwide are vastly impacted by market sentiments and investors tend to react and rebalance their portfolios time to time due to such changes in market sentiments from political events. This systematic review examines the impact of political crisis and election on the capital market returns worldwide. It employs a systematic review research method and has gone through 4573 articles, out of which 62 articles published in reputed journals between 1970 and 2023 were considered for review. Of the methodology of the studies reviewed, 43.5% is quantitative, 27.4% is mixed, 17.7% is qualitative, and the rest is conceptual. Researches published in the context of Asian countries contributed 40% of this reviewed study, followed by Europe, Africa, and North America, each with 10%, South America with 3%, Australia with 1%, and allied countries within unions or agreements with 26%. The results show that political crises significantly impact capital market returns in Asia. Studies in North American context indicate that before elections and during political crises, the capital market volatility significantly rises with decreased capital market returns. In Australia, political events cause financial market fluctuation. In Africa, political instability hinders long-term capital accumulation. Additionally, informal political instability in South America directly affects economic growth, while formal instability indirectly affects economic vulnerability. The outcomes of such research hold practical implications for policymakers in formulating portfolio strategies and, therefore, delineate avenues for research exploring the integrated effects of political events on capital market returns by amalgamating trading information from stock exchanges worldwide.

Published: August 2024

Introduction: Globally, the most common mental disorders in the elderly include dementia (5% - 8%), depression (7%), anxiety disorder (4%), and substance abuse (1%). Moreover, 25% of suicide deaths occur among the elderly. Whether the prevalence rate of psychiatric disorders increases in later life is currently debated in the literature. During the previous two decades of their lives, older adults in Bosnia and Herzegovina have experienced many specific psychosocial circumstances. The experience of war aggression on our country, and the post-war period with a very complex socioeconomic environment of the current socio-political climate, were accompanied by special challenges for the mental health of this population. Motivated by a large number of questions and dilemmas related to the state of mental health of this population, we conducted research at the Department of Psychiatry at the University Clinical Center Tuzla.Objective: Our objective was to investigate psychiatric morbidity and comorbidity in people over 55 years of age.Methods: The research sample consisted of all patients older than 55 years treated at the Department for Psychiatry during 2018 (N=281), divided into four age categories. To obtain data, we used medical documentation, i.e., medical records, and we constructed a special questionnaire for research purposes.Results: Diagnoses by ICD-10 groups: 33.4% of patients in the entire sample had affective disorders (F30.0-F39.0): "young" (39.2%), "middle" (43.3%), "older "(75%) (p<0.001); women had significantly more affective disorders (61.8%) than men (26.8%) (p<0.001). Men had significantly more organic mental disorders (F00.0-F09.0) (63.3%) than women (22.6%) (p<0.001).Hypertensio arterialis was the most common comorbid dg. of the entire sample, without significant differences according to age groups and sex (p>0.05). Diabetes mellitus was the second comorbid dg. By frequency in the total sample (19.6%) without significant differences according to age groups and according to sex (p>0.05).Conclusion: In the entire sample, the most common diagnoses are from the affective disorders group; the most common somatic comorbidities are hypertensio arterialis and diabetes mellitus.

Baltic International Trawl Survey (BITS), är en internationellt koordinerad bottentrålsexpedition i Östersjön med torsk som primär målart. Expeditionen utförs två gånger årligen, i kvartal 1 och 4 och täcker egentliga Östersjön. Sju länder ingår i programmet. Rapporten täcker expeditionen utförd med R/V Svea, 20 – 30 november 2023. Sverige tilldelades 35 stationer. Totalt 38 stationer trålades med TV3L bottentrål varav 4 syrefria tråldrag (som ej trålades på grund av att syrekoncentrationen nära botten var nära 0). En station byttes ut på grund av dubbletter i tråldatabasen. Expeditionen täckte delar av subdivision (SD) 24, 25, 27 och 28 i år. Akustiska data samlades in kontinuerligt under hela expeditionen. Totalfångsten 19 901 kg dominerades av sill, skarpsill, torsk och skrubbskädda. Under denna undersökning fångades totalt 26 olika fiskarter. Biologisk provtagning utfördes på torsk och skrubbskädda. Hydrografiska parametrar såsom salthalt, temperatur och syrekoncentration, mättes på samtliga trålstationer

The Arduino microprocessor boards such as Mega 2560, UNO R3, Leonardo, Micro, and Nano are simple and low-cost tools for real-time measurement and control applications. These Arduino boards cannot be used in distributed systems because they lack the networking capabilities to transfer data across units. In this study, an RS-485 protocol for Arduino boards that operate in Master-Slave networks was developed. Network operations could be carried out independently on the main thread program, and devices in the network could react quickly to information received. This was made possible by the asynchronous serial communication feature and a high-speed timer provided in Arduino boards. The networks designed in this study were applied to an electric vehicle model with all-wheel drive and all-wheel steering capabilities for supermaneuverability as well as a saltwater intrusion early warning system installed in a river entry. The results showed that highly reliable and stable network operations could be achieved, thus extending the usage of popular Arduino boards for networked real-time applications.

Ga2O3 and GaN are promising candidates for the fabrication of high power semiconductor devices due to their wide band-gap range, deteremined from 3.0 eV to 4.9 eV. Among these materials, the GaN/Ga2O3 P-N junction diode has an excellent performance even at high temperatures, making it suitable for high-power applications. In this work, GaN/Ga2O3 P-N junction diodes are investigated using computer-aided design (TCAD) simulations. The properties of the diode were optimized in terms of the thickness of the p-type GaN layer and its doping concentration. It was found that the current-voltage (IV) characteristic of the diode decreases as the thickness of GaN layer increases. To achieve a high current output, the optimized thickness is determined to be 500 nm. Furthermore, the doping concentration within the diode strongly influences the output current. The highest current is obtained for an un-doped GaN sample, and the increase in the doping concentration leads to a decrease in the obtained current.

Disposed batteries contain the hazardous sources that directly impact on the environment. Proper disposal of used batteries is a vital matter because of toxit component found in types of batteries. This study focuses on the reutilization of the disposed Zn-battery graphite to produce graphene oxide (GO) via electrochemical exfoliation. The influence of various electrolytes on the exfoliation process was investigated, and the optimal ID/IG values in Raman spectra were determined as 2.5% for KOH. Scanning electron microscopy (SEM) images confirmed the presence of multi-wall graphene oxide in the exfoliated samples. X-ray diffraction (XRD) spectra displayed a broadening of the peak at 2θ = 26.5°, further supporting the successful formation of graphene oxide. The exfoliated graphene oxide was found not to contain any toxic elements. This highlights the potential of using disposed batteries in producing low cost graphene oxide. The study contributes to environmental protection by repurposing graphite rods and reducing industrial waste.

Any business that wants to compete may need to constantly raise both its output and quality. An effective and popular approach to achieving continuous improvement is known as Lean Six Sigma. This paper demonstrates a successful implementation through a case study in wood manufacturing. The enhancement greatly benefited from the optimization of the production process. The seven quality control tools were integrated into specific systematic steps of the PDCA cycle and DMAIC process, along with lean technology. As a result, this led to an increase in product quality and a decrease in manufacturing errors. Customer satisfaction and market competitiveness have risen as a result. A wood production line's productivity and quality were both improved, and this case study demonstrates the positive effects. It could be considered for implementation in various production or assembly lines in other fields such as electronic, clothing and furniture assembly lines.
