Vários microrganismos, potencialmente patogênicos, podem contaminar superfícies hospitalares, frequentemente manuseadas pelos profissionais de saúde, colocando em risco a segurança dos pacientes e desses profissionais. Buscamos identificar bactérias isoladas de grades de leitos e de bombas infusoras na unidade de terapia intensiva de um serviço público referência em Neurocirurgia. Foram coletadas dez amostras de grades das camas dos pacientes e dez de teclados de bomba infusora de uma unidade de terapia intensiva em março de 2015. Delimitando-se uma área de 10x10cm (100cm²), como parâmetro das coletas realizadas, através de swabs estéreis. Os microrganismos foram isolados, identificados e testados em relação à resistência antimicrobiana. Staphylococcus coagulase negativa foram os microrganismos de maior prevalência, todos apresentando resistência à oxacilina. Enfatizamos a necessidade de técnicas de limpeza padronizadas e do uso de soluções detergentes e desinfetantes em concentrações e em frequência adequadas para a prevenção de infecções associados à contaminação ambiental.
Ensemble Model of Attention Mechanism-Based DCGAN and Autoencoder for Noised OCR Classification
Authors: Xiong Shuguang , Zhang Huitao , Wang Meng
Published: June 2024

Optical Character Recognition (OCR) is a technology that converts images of text into machine-readable formats, essential for digitizing printed texts and enabling digital searches. Traditional OCR methods often struggle with variations in font styles and noise. This paper proposes an innovative approach to enhance OCR classification under challenging conditions by leveraging an ensemble model that combines an Attention Mechanism-Based Generative Adversarial Network (GAN) and an Autoencoder. The GAN generates synthetic data to mitigate the limitations of small datasets, while the autoencoder extracts robust features from noisy images. The model undergoes a two-phase training process, initially learning from the augmented dataset and then fine-tuning on a smaller, labeled dataset. Grad-CAM is used to demonstrate interpretability, highlighting the attention regions during predictions. Experimental results show significant improvements in OCR accuracy and robustness, validating the effectiveness of the proposed method in handling noise and limited training data.

Published: June 2024

Objective: To identify the risk factors that predispose medical students to developing gastric symptoms and their correlation with the level of anxiety. Method: Descriptive, quantitative study, carried out in August/2023. Data were collected using Microsoft Forms and analyzed using Microsoft Excel® and EpiInfo™, using the Chi-square Test and the k Proportions Test. The research was submitted to the Ethics Committee and approved under CAAE: 68496623.5.0000.5370. Results: Among the 210 respondents, students in the basic and clinical cycles presented more risk factors for the development of gastric symptoms. The most frequently mentioned symptoms were heartburn, a feeling of bloating and nausea. The profile most susceptible to the development of these symptoms were women, aged between 21 and 25 years old, not living alone, studying the basic or clinical cycle. Predominantly in each cycle, anxiety was classified as minimal. Conclusion: Intake of fatty foods, low frequency of physical exercise and feeling stressed/anxious were the most prevalent risk factors for the development of gastric symptoms. The proximity to completion of the course, age and the fact that the student lives alone are not related to a greater propensity to develop gastric symptoms.
The mediating role of brand trust in the effect of social media marketing on repurchase behaviour
Authors: Gökerik Mehmet
Published: June 2024

This study investigates the impact of social media marketing activities on consumer repurchase behaviours and the mediating role of brand trust in this process. Analyses indicate that the use of social media platforms enhances consumers' trust in brands, and this trust, in turn, strengthens their intentions to repurchase, creating a positive effect. The findings underscore that social media marketing activities can generate significant value for businesses by boosting consumer interaction and brand trust. This research provides substantial evidence of brand trust's positive and meaningful impact in the relationship between social media marketing and repurchase behaviour and how social media marketing strategies can indirectly influence consumer behaviours. Hence, the study suggests that businesses should design their social media marketing strategies to establish solid and trust-based relationships with consumers, highlighting that this approach can positively affect consumers' repurchase behaviours. These findings demonstrate the strategic importance of social media marketing activities for businesses and how brand trust can be leveraged to maximize benefits from these activities.
A civilizációs államok felemelkedése:civilizációs diskurzus a 2010 utáni Magyarországon
Authors: Dudlák Tamás
Published: June 2024

A tanulmány a mai magyar politikai rendszer civilizációs diskurzusát vizsgálja, illetve a rendszer külpolitikájának makrokulturális és diszkurzív olvasatát kínálja. Kiemelten foglalkozik a magyar politikai vezetésnek a nyugati liberalizmussal szembeni konfrontatív politikájának elemzésével, amelynek során specifikusan a kultúra és az identitás területére fókuszál. A legfőbb állítás szerint a civilizációs diskurzus összefügg az identitáspolitika globális térnyerésével, és az állami szuverenitás elleni folyamatos kihívások közepette az államok hatalmának megerősítését szolgálja. A tanulmányban először a kutatás alapjául szolgáló kereteket és fogalmakat (civilizációs állam, civilizációs diskurzus, virtuális felnagyítás) tárgyalom. Ezt követően, a 2010 utáni magyar helyzet elemzése során a tanulmány szerkezete a magyar kormány diskurzusának civilizációs vonatkozású témái (revizionista múltértelmezés, migráció, segélypolitika, nyugatellenesség, vallásos diskurzus, magyar modell és regionális törekvések) szerint alakul. A tanulmány a következtetésekkel zárul, amelyben a magyar példára támaszkodva a civilizációs államok kilátásait értékelem.
Politikai purifikáció. Morális leértékelés, bűntudat- és szégyenkeltés Márki-Zay Péter miniszterelnök-jelölti kampánykommunikációjában
Authors: Szabó Gabriella
Published: June 2024

A tanulmány a bűntudat és a szégyen kampánykommunikációs használatát kívánja feltárni. A kutatás során az egyesült ellenzék miniszterelnök-jelöltjének közösségimédia-üzenetei alapján regisztrálom és jellemzem a morális leértékelés érzelemkommunikációs fordulatait. 2022-es országgyűlési választások előtt felvett adatok kvalitatív tartalomelemző vizsgálatának tanulsága szerint a Márki-Zay Péter Facebook-oldalán található üzenetek körülbelül 38 százaléka, azaz minden harmadik poszt tartalmaz morálisan leértékelő szöveges vagy verbális megnyilvánulást, ami összhangban van korábbi kutatások megfigyelésével: a választási versenyben a kihívók a politikai retorikájukban hajlamosak a vádaskodó és morális érzelmi nyelvezetet vegyíteni. Az ellenzéki miniszterelnök-jelölt retorikájában azonban az elítélés nem korlátozódik az ellenoldal jelöltjeire, a teljes magyar politikai közösséget készteti morális szembenézésre. A totalitás és kollektív morális értékelésekkel a miniszterelnök-jelölt nem kisebb feladatot vállalt magára, mint a politikai élet megtisztítását. A konklúzió a politikai purifikáció stratégiájának hasznát és kockázatait is felvillantja.

Authors: Airlangga Gregorius
Published: June 2024

Accurately predicting concrete compressive strength is fundamental for optimizing mix designs, ensuring structural integrity, and advancing sustainable construction practices. Increased demands for safer, more durable infrastructure necessitate effective predictive concrete compressive strength models. This research aims to compare the effectiveness of six machine learning models such as Linear Regression, Random Forest, Support Vector Regression (SVR), K-Nearest Neighbors (KNN), Gradient Boosting, and XGBoost to predict concrete compressive strength. Used a dataset of 1030 instances with varying mixture compositions, conducted extensive exploratory data analysis, and applied feature engineering and data scaling to enhance model performance. Assessments were performed with a 5-fold cross-validation approach with the R-squared (R²) metric. In addition, the SHAP value is used to understand the influence of each feature on the compressive strength results. The results revealed that XGBoost significantly outperformed other models, achieving an average R² value of 0.9178 with a standard deviation of 0.0296. Notably, Random Forest and Gradient Boosting also demonstrated robust capabilities. Based on our experiment, these models effectively predicted compressive strengths close to actual measured values, confirming their practical applicability in civil engineering. SHAP values provided insights into the significant impact of age and cement quantity on model outputs. These results highlight the advanced ensemble methods' effectiveness in concrete compressive strength prediction and underscore the importance of feature engineering in enhancing model accuracy.

Published: June 2024

Objective Increased fast food consumption can have adverse effects on health and well-being among adolescents, posing a significant public health concern. The school closures due to the coronavirus disease-2019 (COVID-19) pandemic have led to changes in eating patterns and disrupted a balance diet among adolescents. This study explored the factors associated with fast food consumption among adolescents during school closures due to the COVID-19 pandemic.Methods A total of 1,710 middle and high school students in Gwangju, South Korea participated in a cross-sectional survey. The self-administered questionnaire included items assessing dietary intake, physical activity, sleep, media use, and sociodemographic information. The Patient Health Questonnaire-9, Generalized Anxiety Disorder-7, and three item version of the UCLA Loneliness Scale were also administered. Multivariable logistic regression was used to examine the factors associated with increased fast food consumption.Results Approximately 34.6% of the surveyed adolescents reported increased fast food consumption during school closures, as well as increased sleep duration, increased sedentary behaviors including watching TV and using the internet, and reduced physical activity. Multivariable logistic regression analysis revealed that fast food consumption during school closures was associated with irregular patterns of main meals and sleep, decreased physical activity, increased internet use, and a lack of daytime adult supervision.Conclusion Our results highlight the need for dietary and lifestyle monitoring and guidelines to promote health among adolescents, especially during school closures. In conclusion, nutrition intervention programs aiming to limit fast food consumption and enhance healthy dietary habits among adolescents during long-term school closures are warranted.

Published: June 2024

Objective Anxious depression is a prevalent characteristic observed in Asian psychiatric patients diagnosed with major depressive disorder (MDD). This study aims to investigate the prevalence and clinical presentation of anxious depression in Taiwanese individuals diagnosed with MDD.Methods We recruited psychiatric outpatients aged over 18 who had been diagnosed with MDD through clinical interviews. This recruitment took place at five hospitals located in northern Taiwan. We gathered baseline clinical and demographic information from the participants. Anxious depression was identified using a threshold of an anxiety/somatization factor score ≥7 on the 21-item Hamilton Rating Scale for Depression (HAM-D).Results In our study of 399 patients (84.21% female), 64.16% met the criteria for anxious depression. They tended to be older, married, less educated, with more children, and an older age of onset. Anxious depression patients had higher HAM-D and Clinical Global Impression–Severity scale score, more panic disorder (without agoraphobia), and exhibited symptoms like agitation, irritability, concentration difficulties, psychological and somatic anxiety, somatic complaints, hypochondriasis, weight loss, and increased insight. Surprisingly, their suicide rates did not significantly differ from non-anxious depression patients. This highlights the importance of recognizing and addressing these unique characteristics.Conclusion Our study findings unveiled that the prevalence of anxious depression among Taiwanese outpatients diagnosed with MDD was lower compared to inpatients but substantially higher than the reported rates in European countries and the United States. Furthermore, patients with anxious depression exhibited a greater occurrence of somatic symptoms.

Objective This study aimed to elucidate the distinct response patterns exhibited by patients diagnosed with bipolar disorder (BD) and those with major depressive disorder (MDD) through the application of the short version of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A-SV).Methods A total of 2,458 participants consisting of patients with MDD (n=288), BD (BD I, n=111; BD II, n=427), and control group (n=1,632) completed the TEMPS-A-SV. The response patterns of the participants were classified into distinct profiles using latent profile analysis. The study further examined the impact of covariates such as age, sex, and diagnostic group on derived latent profile memberships.Results The following three latent profiles were identified: High Affective Temperament Group (17.86%), Low Affective Temperament Group (41.25%), and Middle Affective Temperament Group (40.89%). Compared with the patient group with MDD and BD, the control group was more likely to belong in the Low Affective Temperament Group, which showed a higher score on hyperthymic temperament than the Middle Affective Temperament Group. Furthermore, compared with the patients with BD, the MDD patients were more likely to be in the Low Affective Temperament Group rather than the Middle Affective Temperament Group.Conclusion These results indicate that different affective temperaments exist between patients with MDD and BD. Attempting to classify response patterns using the TEMPS-A-SV can help diagnose MDD and BD correctly.

Published: June 2024

Objective This study examined the factors affecting depression, anxiety, and suicidal ideation among patients with coronavirus disease-2019 (COVID-19) during the early phase of COVID-19 in South Korea and investigated the role of stigma in moderating the effects of loneliness on mental health problems among these patients.Methods Conducted as part of the COVID-19 Mental Health Panel Survey over 12 weeks in 2021, this survey enrolled participants aged 15–79 years, applying standardized weights for ratio correction, and collected 640 completed questionnaires. Demographic characteristics were analyzed using descriptive statistics. Suicidal ideation, anxiety, and depression post-COVID-19 were examined using t-tests and logistic regression. The PROCESS macro explored stigma’s moderating effects on loneliness and mental health outcomes.Results Results showed that 7.9% and 10.0% of the enrolled participants were at risk for anxiety and depression, respectively, with 3% contemplating suicide post-COVID-19. Stigma positively impacted depression and anxiety, acting as a significant moderator for loneliness, and mental health, with a stronger effect for higher stigma perception. Unemployment and college education elevated mental health risks in COVID-19 cases. Low health satisfaction and poor sleep were linked to suicidal ideation, while fatigue and COVID-19 stigma increased depression and anxiety risks. Loneliness was significantly associated with suicidal ideation, depression, and anxiety.Conclusion Unemployment, college education, low health satisfaction, and poor sleep were linked to suicidal ideation. Fatigue and COVID-19 stigma raised depression/anxiety risks. Loneliness correlated with suicidal thoughts, depression, and anxiety. Stigma moderated the link between loneliness and mental health issues.

Published: June 2024

Objective Schizophrenia is a common mental disorder, and mitochondrial function represents a potential therapeutic target for psychiatric diseases. The role of mitochondrial metabolism-related genes (MRGs) in the diagnosis of schizophrenia remains unknown. This study aimed to identify candidate genes that may influence the diagnosis and treatment of schizophrenia based on MRGs.Methods Three schizophrenia datasets were obtained from the Gene Expression Omnibus database. MRGs were collected from relevant literature. The differentially expressed genes between normal samples and schizophrenia samples were screened using the limma package. Venn analysis was performed to identify differentially expressed MRGs (DEMRGs) in schizophrenia. Based on the STRING database, hub genes in DEMRGs were identified using the MCODE algorithm in Cytoscape. A diagnostic model containing hub genes was constructed using LASSO regression and logistic regression analysis. The relationship between hub genes and drug sensitivity was explored using the DSigDB database. An interaction network between miRNA-transcription factor (TF)-hub genes was created using the Network-Analyst website.Results A total of 1,234 MRGs, 172 DEMRGs, and 6 hub genes with good diagnostic performance were identified. Ten potential candidate drugs (rifampicin, fulvestrant, pentadecafluorooctanoic acid, etc.) were selected. Thirty-four miRNAs targeting genes in the diagnostic model (ANGPTL4, CPT2, GLUD1, MED1, and MED20), as well as 137 TFs, were identified.Conclusion Six potential candidate genes showed promising diagnostic significance. rifampicin, fulvestrant, and pentadecafluorooctanoic acid were potential drugs for future research in the treatment of schizophrenia. These findings provided valuable evidence for the understanding of schizophrenia pathogenesis, diagnosis, and drug treatment.

Published: June 2024

Objective Spatial normalization is an essential process for comparative analyses that heavily depends on the standard brain template used. Brain morphological differences are observed in different populations due to genetic and environmental factors, causing mismatches in regions when the data are normalized to different population templates. Recent studies have indicated differences between Caucasian and East Asian populations as well as within East Asian populations, suggesting the necessity of population-specific brain templates. Thus, this study aimed to construct a Korean young adult age-specific brain template utilizing an advanced method of template construction to update the currently available Korean template.Methods The KOR152 template was constructed via affine and nonlinear iterative procedures based on prior studies. We compared the morphological features of different population templates (MNI152, Indian_157, and CN200). The distance and volumetric changes before and after registering the data to these templates were calculated for registration accuracy.Results The KOR152 global brain features revealed a shorter overall length than the other population templates. The registration accuracy by distance and volumetric change was significantly lower than that of the other population templates, implying that the KOR152 was more accurate than other templates for the young adult Korean population.Conclusion This study provided evidence for the need for a population-specific template that may be more appropriate for structural and functional studies in Korean populations.

Published: June 2024

Objective This study aims to investigate the thoughts of the general population regarding life-sustaining treatment for both oneself and family members and to assess the factors associated with those thoughts.Methods A total of 1,500 individuals participated in this study by completing a questionnaire consisting of self-reporting items with some instructions, basic demographic information, thoughts on life-sustaining treatment, and psychosocial scales. The disease status was calculated using the Charlson Comorbidity Index. The psychosocial scales included the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Pittsburgh Sleep Quality Index, and Multidimensional Scale of Perceived Social Support.Results The majority of participants did not want to receive life-sustaining treatment for both themselves and their families. However, more people wanted life-sustaining treatment for their family members (35.9%) than for themselves (21.6%). Among the basic demographic characteristics, there were significant differences in age, sex, marital status, living arrangements, occupational status, religion, and disease status. Regarding the psychosocial scales, there were significant differences in the PHQ-9 and GAD-7 scores between the group that preferred life-sustaining treatment for family members and the group that did not.Conclusion The findings suggest that life-sustaining treatment decisions for oneself and for one’s family members can be different. We recommend a more clear expression of one’s preferences regarding the last moments of one’s life, including advance directives.

Published: June 2024

Objective Obsessive-compulsive disorder (OCD) is a psychiatric condition that causes significant distress and social costs and often follows a chronic course with frequent relapses. Approximately 20% of patients do not respond to medication or cognitive behavioral therapy; gamma knife surgery (GKS) has been proposed as a treatment option for these patients. However, research on GKS for OCD patients is rare.Methods In this study, 10 patients with treatment-resistant OCD underwent GKS, and the treatment response and side effects were assessed. The improvement in patients’ obsessive-compulsive symptoms was evaluated using the Yale-Brown Obsessive Compulsive Scale (YBOCS) scores following GKS. Additionally, the characteristics distinguishing the groups with favorable responses to GKS from those with less favorable responses were examined.Results GKS was well tolerated, and patients demonstrated a statistically significant reduction in YBOCS scores before and after GKS (p=0.016). Patients that responded to GKS exhibited distinct characteristics from those who did not respond. Patients who responded poorly tended to present an earlier age of onset, a longer duration of illness, more frequent hospitalizations, poorer social functioning, and a greater incidence of suicide attempts/thoughts.Conclusion This study not only demonstrated that GKS is a safe and effective treatment method for intractable OCD but also revealed characteristics distinguishing patients who respond well to GKS from those who do not. These results may aid in the selection of patients for future application of GKS.

Objective The objective of this study is to compare the psychosocial characteristics of functional dyspepsia (FD) with its subgroups, epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS), against a healthy control group, and to investigate the quality of life (QoL).Methods All of the subjects were 210 adults, 131 patients with FD were diagnosed by gastroenterologist and 79 adults with no observable symptoms of FD were selected as the normal control group. Demographic factors were investigated. The Korean-Beck Depression Inventory-II, Korean-Beck Anxiety Inventory, Korean-Childhood Trauma Questionnaire, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale, and WHO Quality of Life Assessment Instrument Brief Form were used to assess psychological factors. A one-way analysis of variance was used to compare differences among the groups. Further, a stepwise regression analysis was conducted to determine factors affecting the QoL of the FD group.Results Between-group differences in demographic characteristics were not significant. Depression (F=37.166, p<0.001), anxiety (F=30.261, p<0.001), and childhood trauma (F=6.591, p<0.01) were all significantly higher in FD group compared to the normal control. Among FD subgroups, EPS exhibited higher levels of both depression and anxiety than PDS. Social support (F=17.673, p<0.001) and resilience (F=8.425, p<0.001) were significantly lower in FD group than in other groups, and the values were higher in PDS than in EPS. Resilience (β=0.328, p<0.001) was the most important explanatory variable. The explained variance was 46.6%.Conclusion Significantly more symptoms of depression, anxiety, childhood trauma was observed for both FD sub-group. These groups also had less social support, resilience, and QoL than the control groups.

Pertumbuhan pada ternak merupakan salah satu proses biologis yang penting sebagai bentuk ekspresi genetik terhadap sifat-sifat kuantitatif. Penelitian ini bertujuan untuk mengetahui model kurva pertumbuhan berat badan pada sapi Turkish Holstein (TH) jantan. Data yang digunakan dalam penelitian ini berupa data primer dari hasil penelitian Galiç dan Takma (2019) yang berbeda dengan penelitian ini. Estimasi kurva pertumbuhan pada penelitian ini diestimasi menggunakan program komputer CurveExpert 1.4. Hasil penelitian menunjukkan bahwa berat dewasa (asimtot) sapi TH jantan sebesar 600,62 kg (Logistik) dan 688,53 kg (Gompertz). Titik infleksi berat (IW) dan titik infleksi umur (IA) pada model Logistik masing-masing dicapai pada 300,31 kg dan 5 bulan. Sedangkan pada model Gompertz nilai IW dam IA masing-masing dicapai pada 253,14 kg dan 4 bulan. Laju pertumbuhan maksimal (GR) pada sapi TH jantan sebesar 66,07 kg/bulan (Logistik) dan 63,32 kg/bulan (Gompertz). Disimpulkan bahwa model Gompertz memiliki tingkat akurasi yang lebih baik dari model Gompertz karena memiliki nilai simpangan baku (SB) terkecil.
