Machado de Assis
Authors: Teixeira Níncia Cecília Ribas Borges
Published: May 2024

A pesquisa pondera as relações entre literatura e experiência urbana; sob essa perspectiva faz-se o levantamento das representações da cidade do Riode Janeiro, recém-inserida na modernidade e que ainda comporta vestígios do passado colonial. O trabalho tem como objeto central a análise das crônicas produzidas por Machado de Assis, escritor que pode ser considerado retratista de um Rio que se modernizava. O estudo dessas crônicas considera, além do enfoque literário, a configuração histórica e o forte apelo jornalístico desse gênero, que, até pouco tempo, era desconsiderado pelo cânone literário.

Samba-enredo

Published: May 2024

O artigo procura realizar a análise de como a representação ficcional que o romance Samba-enredo desenvolve está articulada à esfera de certos referentes que processam e projetam discursos imagéticos; discursos cuja natureza é entendida quase sempre como execução do simulacro e cuja função estaria direcionada para provocar a alienação humana, com o que o romance se organizaria em termos potenciais sobre um universo esvaziado de realidade.

Drummond diferente
Authors: Souza Jr José Luiz Foureaux de
Published: May 2024

A poesia e a prosa de Drummond são, constantemente, revisitadasno intuito de realizar as mais diversas leituras. Dois textos em especial mechamam a atenção aqui, o conto “O sorvete” e o poema “Rapto”. Emambos é possível “ler” a operacionalidade teórico-interpretativa do princípioda homossociabilidade, como um vetor a mais para a orientação da jávasta fortuna crítica do autor. Severo e circunspeto por natureza, o poetaconstruiu uma persona poética que está longe de explicitar o referidoprincípio, enquanto tema de “realização” poético-ficcional em seus textos.No entanto, o mesmo lirismo que já é reconhecido pela crítica faz renovaros possíveis sentidos dos textos drummondianos, na perspectiva da recepçãoliterária. Assim a historiografia literária vê contemplada, mais uma vez,a demanda de releitura de seus(s) próprio(s) cânone(s), fazendo comque o exercício crítico-interpretativo seja praticado, acrescentandoelementos diferenciados à já variada fortuna crítica do autor.
Dois estados existenciais na poética drummondiana

Tomando o poema “A Flor e a Náusea” como um ponto de partida,este trabalho investigará a provável presença de duas atitudes existenciaisna poética de Drummond. Parece que estas posturas criam um paradigmaestrutural que reaparece em vários outros poemas e estabelece as basespara uma adequada compreensão da provável atitude pessimista.

Brejo das Almas de Drummond
Authors: Santos Vivaldo
Published: May 2024

O livro Brejo das Almas (1934) de Carlos Drummond de Andradeocupa um lugar marginal dentro da crítica drummondiana, sobretudodiante da notada centralização no elemento subjetivo. Na maioria dasvezes a crítica o caracteriza como simples extensão da subjetividade líricainstituída em Alguma poesia, ou ponto de transição entre a poesia irônicae individualista da chamada primeira fase drummodiana, e a poesiasocialmente comprometida para a qual Sentimento do mundo (1940)acena. Pouca atenção tem sido prestada à particularidade poética deBrejo das Almas. A hipótese aqui desenvolvida é a de que o tom decadente,niilista, e dionisíaco que se vê refletido no plano temático e no plano dalinguagem na constituição da subjetividade neste poemário aponta paraum diálogo de Drummond com o discurso da modernidade, principalmentecom respeito ao “Desencantamento do Mundo” diante da chamada “Mortede Deus.”

Published: May 2024

In recent years, the additive manufacture was popularly used in tissue engineering, as the various technologies for this field of research can be used. The most common method is extrusion, which is commonly used in many bioprinting applications, such as skin. In this study, we combined the two printing techniques; first, we use the extrusion technology to form the ceramic scaffold. Then, the stem cells were printed directly on the surface of the ceramic scaffold through a piezoelectric nozzle. We also evaluated the effects of polydopamine (PDA)-coated ceramic scaffolds for cell attachment after printing on the surface of the scaffold. In addition, we used fluorescein isothiocyanate to simulate the cell adhered on the scaffold surface after ejected by a piezoelectric nozzle. Finally, the attachment, growth, and differentiation behaviors of stem cell after printing on calcium silicate/polycaprolactone (CS/PCL) and PDACS/PCL surfaces were also evaluated. The PDACS/PCL scaffold is more hydrophilic than the original CS/PCL scaffold that provided for better cellular adhesion and proliferation. Moreover, the cell printing technology using the piezoelectric nozzle, the different cells can be accurately printed on the surface of the scaffold that provided and analyzed more information of the interaction between different cells on the material. We believe that this method may serve as a useful and effective approach for the regeneration of defective complex hard tissues in deep bone structures.
Paraphrasing Prowess: Unveiling the Insights of EFL Students and Teachers on QuillBot Mastery
Authors:   Department of English, College of Languages and Translation, Najran University, Najran, Saudi Arabia, Alzubi Ali A. F.
Published: May 2024

Artificial Intelligence-mediated (or AI-mediated) technology has significantly enhanced teaching and learning environments, particularly in developing students’ paraphrasing skills. However, research on students’ and teachers’ perceptions of AI tools in academic writing is limited. As a result, this study aims to identify English as a Foreign Language (EFL) students’ and teachers’ perceptions of using QuillBot to learn paraphrasing skills. It also examines whether students’ gender and level of study, as well as teachers’ qualifications and experience, affect their responses. The study employed a descriptive survey method along with a convenience sampling method to select a study sample of 115 students and 44 teachers. Additionally, a semi-structured interview was conducted with a purposive sample of 13 students to explore their views on utilizing QuillBot. The findings revealed that (i) students and teachers perceived that QuillBot can greatly enhance paraphrasing skills; (ii) students’ gender and level of study did not affect their answers as well as teachers’ qualifications and years of experience; (iii) the participants’ role (whether student or teacher) did not impact their responses; and (iv) students had a high perception of using QuillBot. The researchers recommend QuillBot as a learning tool for mastering paraphrasing skills.

Is Undesired Pregnancy from Rape Considered Bodily Injury?: A Comparative Legal Study of Cases in Korea and the US
Authors:   The Legal Studies Institute of Chosun University, Kim Jong Goo , Im Won Sik
Published: May 2024

Recently, in the Supreme Court of Korea, there has been controversy over whether the victim's pregnancy is bodily injury in the case where the defendant, a stepfather, sexually assaulted an 11-year-old stepdaughter to become pregnant, and in the case where the defendant sexually assaulted a friend of his wife who was asleep under the influence of alcohol at his home. The prosecutor regarded the undesired pregnancy as bodily injury and prosecuted the defendant for aggravated-rape and aggravated-quasi-rape in these cases, but the Supreme Court of Korea admitted only rape and quasi-rape because the undesired pregnancy did not constitute bodily injury. Some scholars argue that pregnancy due to rape should be considered bodily injury, but discussions in Korea are still insufficient.
Even in the context of US precedents, the question of whether a rape victim's pregnancy constitutes substantial bodily injury has arisen in numerous statutory rape cases, including a case in which a stepfather sexually assaulted a 13-year-old stepdaughter for months, leading to pregnancy, and then aborted. The pregnancy of a rape victim negatively affects the victim's physical and mental aspects. Therefore, it is argued that the physical and mental effects of pregnancy are the same as substantial bodily injury, and that the pregnancy of rape victims should be recognized as a factor that increases the punishment of rape. However, US precedents and legislation have different positions on whether to view physical changes caused by the pregnancy of rape victims as elements of aggravated punishment.
Korean courts have not yet recognized the unwanted pregnancy of rape victims as bodily injury. However, in the United States, legal precedents sometimes consider the pregnancy of rape victims as bodily injury, and individual state legislations also recognize this. This paper compared and examined related precedents and legislation in Korea and the United States, and studied the question of whether to view the unwanted pregnancy of rape victims as bodily injury. In conclusion, the author of this paper argues in favor of interpretive and legislative theories that advocate for viewing the pregnancy of rape victims as bodily injury.
Evaluation of hematological parameters and platelet yield in voluntary blood donors by plateletpheresis: a one-year study at the blood centre in a teaching hospital
Authors: Gulia Sandhya Panjeta , Rattan Akshita , Singh Sonia , Gupta Dalip
Published: May 2024

Background: The present study was planned to compare of pre and post donation hematological parameters in healthy donors by plateletpheresis. Also to assess the platelet yield following plateletpheresis procedure with its correlation to pre donation platelet count.
Methods: This is a retrospective cross-sectional study carried out in the Blood Centre of a tertiary care hospital in Haryana, India between January to December 2022. Plateletpheresis was done on Trima Accel Automated Collection System with ACD‐A as an anticoagulant. The data was collected from the hospital for hematological parameters (Hb, hematocrit, Total WBC count, total platelet count) pre and post donation. Categorical data is presented as frequency, percentage, mean±SD range. Correlation was established between the pre donation platelet count and the platelet yield.
Results: A total of 125 donors were included in the study with majority of the donors 69 (55.2%) in the age group 21-30 years. Mean age of the donors included in the study was 31.58±7.5 years. The levels of hemoglobin dropped from 14.16±0.95 to 13.92±1.002 gm/dl, hematocrit dropped from 41.19±1.33 to 40.91±2.89%, total WBC count reduced from 7.64±1.38 to 7.61±1.36 103/ l and platelet count dropped from 279.5±62.96 to 259.9±58.38 lac/ l. There was a significant drop in the levels of platelet post donation by 7.01% compared to pre donation levels. majority of the donors (44%) had a mean platelet yield 2.49±0.33 with a platelet count between 1.5-2.5x1011/l. The maximum platelet yield was 4.93±0.34 in 6% donors with pre-donation platelet count of >4.5 5x1011/l. A linear significant relationship was established between the platelet count and the platelet yield (r=0.99).
Conclusions: There were significant changes in the pre donation and post donation hematological parameters among the donors. It was concluded that donors with a high pre-donation platelet count can be considered for better platelet yield.
Assessment of knowledge, attitude and practice to promote hand hygiene among undergraduate medical and nursing students in a teaching hospital
Authors: Shreya Mavoori , Badave Gitanjali Kailas
Published: May 2024

: A considerable number of epidemiological evidences proved that efficient hand hygiene practices has reduced the risk of infection cross-transmission in hospital facilities. Despite the effortlessness and simplicity of the practice, compliance with hand hygiene among health care workers has been relatively very less. There is a significant lack of evidence regarding infection control training among undergraduate medical and nursing students, hence it becomes essential to re-examine the efficacy of our hand hygiene sessions and conduct programs, CMEs, workshops frequently to keep health care workers sensitized and oriented towards hand hygiene.

: The present study was undertaken to assess the overall exposure of medical and nursing students towards basic hand hygiene practices through a knowledge, attitude and practice questionnaire based cross- sectional study. 100 medical and 100 nursing students were grouped into good, moderate and poor categories, based on scores from the questions testing the overall knowledge of hospital acquired infections, attitude towards hand hygiene and actual practice at the field level.

: The present study showed poor knowledge among medical and nursing students i.e 41% and 60% of the participants respectively. Nursing staff showed good attitude when compared to medical students (71% and 56%). Regardless of the knowledge, practice of hand hygiene was good in both the groups 59% of medical and 71% of nursing students. On the whole, in comparison nursing population displayed better results compared to undergraduate medical student population. Nevertheless, evidently showing unsatisfactory results among both the study groups in the grounds of knowledge.

: Therefore, the study concludes that knowledge and exposure to hand hygiene practices should be improved in undergraduate curriculum for both medical and nursing students which provides an opportunity to correct the bed side hygiene practices of the future health care providers at the foundation level.
Item Analysis of Sociocultural Influences in Verbal Ability Testing Using the Woodcock-Johnson IV COG
Authors: Mrhálek Tomáš , Hricová Alena , Ondrášek Stanislav
Published: May 2024

The article presents the results of a study that examines the impact of sociocultural environment on the development of verbal skills in Romani children aged 7–11 years, with a particular emphasis on children from socially excluded localities. The results are based on a verbal test derived from the Woodcock-Johnson Cognitive Ability Test (WJ IV COG), which was processed using item analysis according to the Rasch model. The main results are based on analysing the differential function of individual items within the verbal tests within the research group (N = 399) compared to the normative sample of the Czech population (N = 936). A secondary goal is to compare Romani children originating from socially excluded areas (N = 204) with those from non-excluded areas (N = 195). Regarding item comparisons between the majority and sample groups, they reveal significant disparities in 14 items (70%) of the Synonyms subtest and 9 items (45%) of the Antonyms subtest. The results highlight the crucial role of a more limited vocabulary, particularly in formal linguistic expressions by Romani children. The presented words representing differently functioning items can also serve as a basis for linguistic analysis and can be applied in assessing educational needs. When comparing the group of children based on their residence in a socially excluded locality, significant differences in the DIF were identified for one item from the Synonyms subtest and three items from the Antonyms subtest.
How institutions are related to agriculture? Systematic literature review
Authors: Barszczewski Michał
Published: May 2024

In this paper, the author reviews the literature on institutions and their relations with agricultural economics. The aims of the article are to clarify the definition of an institution, indicate its relevance from the perspective of agricultural economics and propose a method of institution classification. Using the PRISMA method, 35 articles were selected out of 238 articles from the Web of Science database that met the established requirements (i.e. they were simultaneously related to institutions, economic performance and the agricultural sector). Based on the identified articles as well as the preliminary literature review it can be concluded that there is a lack of research that precisely defines institutions and examines the historical context at the same time. There are not many papers in which authors assess relations between institutions.
No Overactivism: Robert Lewandowski’s Use of Gentle Protest to Avoid National Political Backlash
Authors: Bridgman Timothy
Published: May 2024

The last few years have seen the return of athlete activism into major international sports events held worldwide as a mindset based on social responsibility and political freedom of speech has spread into the selfperception of many current top athletes. However, while these athletes may have experienced a recent personal transformation, the national political backlash accompanying activism remains set in a long tradition condemning political interference in sports. This article provides a background on the tradition of castigating political athlete activists, a theory on why and how national political backlash occurs, and evidence on the successful use of gentle activism to avoid such scenarios. The research examines a case study of Polish international footballer Robert Lewandowski’s ‘pointing the finger’ during a World Cup qualifier in 2022 to illustrate how alternative moderate forms of activism can be adopted. This study aims to introduce the term ‘overactivism’ into the politics of sport as a concept where the athlete prioritises retaining long-term political relevancy over maximising the political impact of a single event.
Critical Review: The Impact of Political Prisons on Political Participation (The Case of Egypt’s Muslim Brotherhood)
Authors: Khattab Fatma
Published: May 2024

Many revolutionary figures throughout history proved their corrupted intention whenever they reached authority (e.g., the Iranian revolution, Burma’s Aung Suu Kyi). Some political leaders in Egypt claim they own it all depending on whom they represented in the latest major social uprising, and they define what is moral or who shall be the target for future political manoeuvres of the ruling military regime. With no one taking the lead for democratising the system, and the ex-minister of defence, incumbent President Abdelfattah Al-Sisi allegedly caught up in an internal fight with a corrupt government, the country’s better future seems to be a long and arduous struggle away. This paper addresses the overlapping and misleading media and political utterances of Egyptian opposition, who either takes a popular stand or loses followers through democratisation itself.
Escalation Ladder and the Game of Chances in the Ukraine war of 2022
Authors: Nycz Grzegorz
Published: May 2024

The paper refers to the most recent developments during the 2022–2023 Ukraine war, analysed from the perspective of selected insights derived from deterrence studies, most notably the escalation ladder. The reason for the publication is to point out dangerous escalatory steps in the context of Putin’s Russia-Ukrainian war, including the abolishment of strategic arms control and tactical nuclear weapons deployment in the EU neighbourhood. V. Putin’s regime’s steps towards seizure or control of Ukraine’s largest nuclear power plant were discussed internationally as a severe humanitarian hazard. The pre-1989 deterrence debate could add a vital research perspective missing in the analytic frames of the New Cold War. Notably, the developments of the 2023 conduct of the Ukraine war with the support of the West countering the impact of a nuclear crisis scenario (tactical arsenal employment) could be analysed in the context of earlier concepts of limited war (1960s), as well as further elaborations on conditions of mutual vulnerability.
Relacyjność w stosunkach Chin z Europą Środkowo-Wschodnią
Authors: Kowalski Bartosz
Published: May 2024

Przyjęta na potrzeby niniejszej książki metoda studium przypadku koncentruje się na przykładzie Czech i odpowiedzi na pytanie, w jaki sposób teoria relacyjności pozwala zrozumieć, dlaczego Chiny zdołały w Czechach zbudować, a następnie stracić, istotne wpływy. Jednocześnie intencją autora było ukazanie szerszego kontekstu zmian jakie dokonały się w stosunkach Chin z państwami regionu Europy Środkowo-Wschodniej po 2012 roku. Kluczowe dla zrozumienia chińskiego podejścia relacyjnego do Europy Środkowo-Wschodniej jest wzięcie pod uwagę peryferyjności tego regionu w percepcji chińskich elit politycznych i postrzeganie jego demokratyzacji w latach 90. XX wieku jako procesu narzuconego z zewnątrz (przez Zachód) i przyporządkowanie go do zbioru relacji z państwami rozwijającymi się (Globalnego Południa).
Choć państwa Europy Środkowo-Wschodniej mają dla Chin relatywnie niewielki potencjał jako partnerzy gospodarczy, to ze względu na domniemaną słabość (powierzchowność) i egzogenny charakter demokracji i rządów prawa, postrzegane były jako podmioty podatne na prowadzenie polityki relacyjnej i budowania poparcia dla chińskiej agendy politycznej. Autor dowodzi, że percepcja regionu jako obszaru peryferyjnego, wpływa na narzędzia polityki zagranicznej (m.in. działania nieformalne i mechanizmy pozyskiwania elit) i ekonomii politycznej, wykorzystywanej przez Chiny wobec państw rozwijających się.
Validation of chest trauma scoring systems in polytrauma: a retrospective study with 1,038 patients in Korea
Authors: Kim Hongrye , Lee Mou Seop , Yoon Su Young , Han Jonghee , Lee Jin Young , Seok Junepill
Published: May 2024

Purpose: Appropriate scoring systems can help classify and treat polytrauma patients. This study aimed to validate chest trauma scoring systems in polytrauma patients.Methods: Data from 1,038 polytrauma patients were analyzed. The primary outcomes were one or more complications: pneumonia, chest complications requiring surgery, and mortality. The Thoracic Trauma Severity Score (TTSS), Chest Trauma Score, Rib Fracture Score, and RibScore were compared using receiver operating characteristic (ROC) analysis in patients with or without head trauma.Results: In total, 1,038 patients were divided into two groups: those with complications (822 patients, 79.2%) and those with no complications (216 patients, 20.8%). Sex and body mass index did not significantly differ between the groups. However, age was higher in the complications group (64.1±17.5 years vs. 54.9±17.6 years, P<0.001). The proportion of head trauma patients was higher (58.3% vs. 24.6%, P<0.001) and the Glasgow Coma Scale score was worse (median [interquartile range], 12 [6.5–15] vs. 15 [14–15]; P<0.001) in the complications group. The number of rib fractures, the degree of rib fracture displacement, and the severity of pulmonary contusions were also higher in the complications group. In the area under the ROC curve analysis, the TTSS showed the highest predictive value for the entire group (0.731), head trauma group (0.715), and no head trauma group (0.730), while RibScore had the poorest performance (0.643, 0.622, and 0.622, respectively)Conclusions: Early injury severity detection and grading are crucial for patients with blunt chest trauma. The chest trauma scoring systems introduced to date, including the TTSS, are not acceptable for clinical use, especially in polytrauma patients with traumatic brain injury. Therefore, further revisions and analyses of chest trauma scoring systems are recommended.
An Exploratory Study on the Development and Validation of a Major Competency Diagnosis Tool in the Department of Social Welfare: Focusing on the Case of U University
Authors:   Korean Academy Welfare Counselling, Lim Sung Ok , Lee Joo Yeon
Published: May 2024

The purpose of this study is to define the concept of major competencies in the Department of Social Welfare and to develop and validate a major competency measurement model. Literature analysis, department consumer satisfaction survey, major curriculum committee, and FGI were conducted to define the four competencies and the concept of the lower eight competencies. A Delphi survey (1st) was conducted on social welfare professors and field experts to validate major and sub competencies. Based on the four major competencies and the eight sub competencies of the social welfare department, a new preliminary question was developed, and a preliminary content validity test was conducted through the Delphi survey (2nd) targeting the expert panel group. In the second Delphi survey, two questions with low content validity were deleted, and a preliminary test was conducted for college students in the Department of Social Welfare to analyze the reliability and validity of the diagnostic tool. The items with the highest factor loading value were selected in order to reduce them to the final 66 questions, and a diagnostic tool to measure major competency was completed. This makes it possible to diagnose and analyze the level of major competency of students in the Department of Social Welfare. In addition, the results of this study are expected to be usefully used by the Department of Social Welfare to manage the quality of major education, such as improving the curriculum based on quantitative data.
The Impact of Parental Autonomy Support on College Students’ Psychological Happiness: Validating the Mediating Effect of Positive Psychological Capital
Authors:   Korean Academy Welfare Counselling, Kim Tae-Ryang , Ko Soohyun
Published: May 2024

This study aims to validate the role of positive psychological capital in the structural relationship between parental autonomy support and college students’ psychological happiness based on self-determination theory. The study also aims to explore practical interventions to promote psychological happiness among college students based on empirical evidence. The research method was to distribute questionnaires to college students in Busan Metropolitan City and Gyeongsangnam-do Province from September 2023 to November 2023, and statistically analyzed using SPSS 21.0 and AMOS 21.0 programs based on 289 data without missing data. The findings were as follows First, higher levels of parental autonomy support were associated with higher levels of psychological well-being. Second, higher levels of parental autonomy support were associated with higher levels of positive psychological capital. Third, higher levels of positive psychological capital were associated with higher levels of psychological happiness. Fourth, indirectly, positive psychological capital was found to have a partial mediating effect on the relationship between parental autonomy support and psychological happiness. These findings have implications for providing an empirical basis for enhancing self-determination and promoting psychological happiness in college students, who are pre-socialized adults. Therefore, it can be applied directly to parent education programs that enable parents to promote their positive psychological capital and psychological well-being through supporting college students’ autonomy, and indirectly to family counseling and family therapy to promote family members’ self-determination.
A New Paradigm in Cancer Treatment: Identifying and Targeting Clonal Mutations
Authors: Renteln Michael
Published: May 2024

Recently concluded, large-scale cancer genomics studies involving multiregion sequencing of primary tumors and paired metastases appear to indicate that many or most cancer patients have one or more “clonal" mutations in their tumors. Clonal mutations are those that are present in all of a patient’s cancer cells. Achilles Therapeutics is currently the only company specifically targeting clonal mutations. However, they are doing so with tumor-derived T cells. To address the potential limitations of immunotherapy, I have devised another approach for exploiting clonal mutations, which I call “Oncolytic Vector Efficient Replication Contingent on Omnipresent Mutation Engagement” (OVERCOME). The ideal version of OVERCOME would likely employ a bioengineered facultative intracellular bacterium.

Published: May 2024

A special vibration damper is proposed for material property identification through a scratching process on a vibrating object. This paper presents the design and working principle of a scratching damper based on a scratch test device. A non-contact electromagnetic shaker is used to generate the shaking force for the vibration of the tested object. The required pressure on the scratched material during the scratching process is generated by a compression spring and adjusted by changing the amount of compression of the spring. The proposed damper is designed and tested on extruded aluminum samples for the determination of its Young’s modulus and hardness and validated by using the standard test instruments. Observations of physical dimensions of the scratching tracks are determined by microscope and were utilized to compute the scratching energy factor. Load curves are obtained at different pressure of the scratching process. The hysteresis loop energy during the scratching process of the tested object is measured and used for the determination of material properties of the object. Furthermore, energy conservation law, scratch energy release rate and loop energy release rate are used to determine the Young’s modulus and hardness of the sample. The measurement accuracy of the modulus and hardness of the tested sample is evaluated. The proposed method of material testing has several advantages over the traditional methods such as low cost and high repeatability, and may be used as an alternative to the standard modulus and hardness testers.

This study aimed to develop a laboratory-scale direct air capture unit for evaluating and comparing amine-based adsorbents under temperature vacuum swing adsorption conditions. The experimental campaign conducted with the direct air capture unit allowed for the determination of equilibrium loading, CO2 uptake capacity, and other main performance parameters of the investigated adsorbent Lewatit VP OC 1065®. The investigations also helped to understand the co-adsorption of both CO2 and H2O on the tested material, which is crucial for improving temperature vacuum swing adsorption processes. This was achieved by obtaining pure component isotherms for CO2 and H2O as well as three different co-adsorption isotherm models from literature. It was found that the weighted average dual-site Toth model emerged as the most accurate and reliable model for simulating this co-adsorption behavior. Its predictions closely align with experimental data, particularly in capturing the adsorption equilibrium at various temperatures. It was also observed that this lab-scale unit offers advantages over thermogravimetric analysis when conducting adsorption experiments on the chosen amine. The final aim of this study is to provide a pathway to develop devices for testing and developing efficient and cost-effective adsorbents for direct air capture.

Background and Objectives. Prevalence of GERD is increased among individuals with obesity and RYGB is considered as the most effective procedure to control GERD and obesity. However, some patients continue to have GERD after RYGB. The aim of the study was to investigate the prevalence and the risk factors of GERD after RYGB. Material and Methods. This prospective study included 180 patients operated with RYGB and followed for on average of 12.2 (0.6) years. 126 (70%) patients agreed to participate in online consultations and provided data on weight, GERD symptoms, filled GERD-HRQL, TFEQ-18 and GSRS questionnaires. Results. The average age before surgery was 42.7 (10.5) years and BMI was 45.2 (6.4) kg/m2. 128 (71.1%) were females and preoperative GERD was diagnosed in 74 (41.1%) patients. At 12 years follow-up the mean %EBMIL and %TWL were 60.37 and 25.73, respectively. The median %WR was 18.0 (39.0). The GERD was present in 30 (23.8%) patients, of whom 12 (40%) continued to have GERD symptoms and 18 (60%) developed de novo GERD. The GERD-HRQL score significantly decreased from 3.0 (8.0) at baseline to 2.0 (5.0) (p=0.028) at 12 years. GSRS Diarrhea and Indigestion median scores increased significantly, from 1.33 (0.67) to 1.5 (2.42) (p 3.2.

Published: May 2024

The precise regulation of hinge moment and pitch angle driven by the pitch regulated mechanism is crucial for modulating thrust requirements and ensuring stable attitude control in Martian coaxial rotorcraft. Nonetheless, the aerodynamic hinge moment in rotorcraft presents time-dependent dynamic properties, posing significant challenges for accurate measurement and assessment for such characteristics. In this study, we delve into the detailed aerodynamic hinge moment characteristics associated with the pitch regulated mechanism of Mars rotorcraft under a spectrum of control strategies. A robust computational fluid dynamics model has been developed to simulate rotor’s aerodynamic loads, accompanied by a quantitative hinge moment characterization that takes into account the effects of varying rotor speeds and pitch angles. Our investigation has yielded a thorough understanding of the interplay between aerodynamic load behavior and rotor surface pressure distributions, leading to the creation of an empirical mapping model for hinge moments. To validate our findings, we engineered a specialized test apparatus capable of measuring the hinge moments of the pitch regulated mechanism, facilitating empirical assessments under replicated atmospheric conditions of both Earth and Mars. The result indicates aerodynamic hinge moments depend non-linearly on rotational speed, peaking at a 0° pitch angle and showing minimal sensitivity to pitch under 0°. Above 0°, hinge moments decrease, reaching a minimum at 15° before rising again. Simulation and experimental comparisons demonstrate that under Earth conditions, the aerodynamic performance and hinge moment errors are within 8.54% and 24.90%, respectively. For Mars conditions, errors remain below 11.62%, proving the CFD model’s reliability. This supports its application in the design and optimization of Mars rotorcraft systems, enhancing their flight control through accurate prediction of aerodynamic hinge moments across various pitch angles and speeds.

Air pollution is a situation that negatively affects the health of humans and all living things in nature and causes financial damage to the environment. In the case of air pollution, harmful and foreign substances in the air reach an amount and density above normal values. Air pollution also causes climate change, which affects global warming. Particulate matter is a harmful substance that harms the health of humans and other living things, causes air pollution, increases radiation, and negatively affects cloud formation. Particulate matter is extremely small solid particles and liquid droplets suspended in the air. PM10, which is less than 10 microns in diameter, is defined as small particles that can remain in the air for a long time and settle in the respiratory tract, damaging the lungs. Many criteria affect PM10 density and changes in density. The main criteria are vehicle traffic and fuel consumption, industrialization, coal, fuel oil and wood-burning heaters, greenhouse gas impact, and unregulated urbanization. It is important to identify the underlying causes of air pollution caused by PM10. In this context, these criteria need to be evaluated to minimize the negative effects of PM10. In the study, monthly average PM10 data between 2019 and 2023 obtained from the Air Monitoring Station in Kocaeli, Türkiye are used. After determining the criteria affecting PM10, the criteria are prioritized with the Intuitionistic Fuzzy AHP (IF-AHP) method by taking expert decision-maker opinions. The proposed decision-making model aims to guide obtaining the important causes of PM10 emission in terms of danger and focusing on these causes. Additionally, PM10 data is analyzed in the context of Covid-19 and a statistical analysis is made. One-way ANOVA is used to evaluate whether there is a significant difference in the average monthly data over the years. Games-Howell test, one of the post-hoc tests, is used for differences between groups (years). The study is important in that it provides a focus on the criteria affecting PM10 with an intuitive fuzzy perspective, along with statistical analysis.

Objectives. To describe national and city-level fatal drug overdose trends between 2005 and 2021 in Mexico.

Methods. We calculated fatal overdose rates at the city level in 3-year periods from 2005 to 2021 and annually at the national level for people aged 15 to 64 years in Mexico. We calculated rate differences and rate ratios for each city between periods.

Results. The national fatal overdose rate was 0.53 overdose deaths per 100 000 population and was almost twice as high in urban than in nonurban areas. The national fatal overdose rate was stable over the period 2005 to 2014 and increased monotonically to a peak in 2021. Fatal overdose rates varied across cities. Cities with the 8 highest fatal overdose rates in the period were all in states along the US–Mexico border.

Conclusions. Fatal overdoses have doubled over the past 15 years in Mexico. Overdose rates are particularly high and increasing in cities close to the US–Mexico border.

Public Health Implications. There is a need for enhanced overdose surveillance data and coordinated harm reduction strategies, particularly in the northern border region of Mexico. ( Am J Public Health. 2024;114(7):705–713. https://doi.org/10.2105/AJPH.2024.307650 )
