Chicken farming is a form of agribusiness that is capital intensive. Broiler chicken is one of the farms if it is developed to have good prospects. Businesses in the field of animal husbandry in the form of broiler cultivation can establish partnerships. A partnership is a form of cooperation that applies profit sharing. The broiler cooperation program aims to establish mutually beneficial and reinforcing business cooperation and mutual trust between farmers and the core party (business partners or investors). Qualitative analysis was used in this study with a descriptive qualitative model. The study results indicate that the system is a partnership cooperation system, with farmers as plasma following the policy from its core (the investors). The policy on delivery issues already exists. Marketing has been regulated by the core party so that, in this case, the breeder only takes care of it. Profit sharing in partnership applies to an agreement where the nucleus already gives a benchmark price.

Sounding Moravian Identity at the Salem Centennial of 1866
Authors: Malone Ryan M.
Published: April 2023

In January 1866, Moravians in Salem, North Carolina, began formulating plans to celebrate the community’s centennial. Cognizant of their restrained financial resources in the wake of the American Civil War, the community resolved to “get up a celebration in every respect, both outwardly and inwardly.” While organizers’ visions revealed novel approaches to many aspects of the two-day-long affair, Edward Leinbach’s approach to the musical components of the celebration bore out in ways that left enduring marks on a community in need of revitalization, growth, and a renewed sense of community. While dutifully honoring the past, the program Leinbach devised and executed performed Moravianism in distinctly new ways that foreshadowed the cultivation of a postbellum Southern Moravian identity.

AN OVERVIEW OF THE EXISTING TEXT-TO-SPEECH(TTS) ALGORITHMS BASED ON DEEP LEARNING
Authors: Nikoghosyan K.H.
Published: April 2023

Text-to-speech technology has been around for a long time, but it is still considered challenging. The creation of human-like synthesized speech requires the solution of
many tasks. As an example, the definition of intonation, the polyphony of systems, the
combination of pairs of phonemes without audible flaws, and the definition of prosody.
Various methods exist for synthesizing speech from the text, including parametric
synthesis, compilation synthesis, domain-specific synthesis, and full speech synthesis by rules. With the advent of the necessary computing resources and the accumulation of sufficient data for training, machine learning methods have become widely used in speech synthesis. With significant improvements in text-to-speech algorithms, text-to-speech is now widely used in mobile devices, smart speakers, and voice assistants. In spite of this, the algorithms of this class, developed at the present time, are not always able to complete the assigned task correctly. In some cases, they are unable to correctly put stress on the right parts of the text or speak with the right intonation.
In this study, the existing text-to-speech deep learning algorithms and models are
reviewed and compared. The comparison is made by taking into account the positive and negative aspects of the algorithms, the complexity of implementing the algorithms, and the availability of the existing libraries for implementation. We consider the following algorithms as the main ones: WaveNet, DeepVoice 3, Tacatron 2, and Transformer.

Рассмотрена однопараметрическая обобщенная проблема собственных значений-функций и собственных векторов-функций, когда в качестве матрицы правой части выступает транспонированная матрица левой части. Это важный частный случай однопараметрической обобщенной проблемы, состоящeй из трех этапов вычислений. На первом этапе задача для пары матриц левой и правой частей сводится к обычной спектральной задаче с некоторой трансформирующей матрицей, для
определения которой применяются аналитический и численно-аналитический методы. При аналитическом методе используются методы определения однопараметрических обобщенных обратных матриц. При численноаналитическом методе в соответствии с известными подходами используются последовательные и параллельные вычислительные процедуры. В обоих методах
в качестве основного математического аппарата выступают дифференциальные преобразования, позволяющие получить легко реализуемые средствами современных информационных технологий вычислительные процедуры, обладающие высокой вычислительной эффективностью.
На втором этапе решается задача определения собственных значенийфункций найденной трансформирующей матрицы. Рассматриваются возможные аналитическое и численно-аналитическое решения. В последнем случае используются известные неявные и явные вычислительные схемы, основанные на дифференциальных преобразованиях.
На третьем этапе решается задача определения собственных векторовфункций трансформирующей матрицы. Рассматриваются возможные аналитическое и численно-аналитическое решения.
Рассмотрен модельный пример. Показано точное совпадение аналитическии численно-аналитически определенных трансформирующих матриц редуцированной эквивалентной задачи. Показано приемлемое совпадение аналитических и численно-аналитических решений собственных значений-функций в окрестности центра аппроксимации, а также аналитических и численно-аналитических решений собственных векторов-функций в окрестности центра аппроксимации. На всех этапах вычислений численно-аналитические решения восстанавливаются на основе использования дифференциально-тейлоровских преобразований.

Introduction: Myocardial steatosis, a poorly documented pathology, is characterized by the accumulation of abnormal amounts of triglycerides in the cardiomyocytes. Myocardial steatosis is generally asymptomatic, but it can be the cause of heart failure. It is primarily of hypoxic or metabolic origin.

Case Report: We report a case of postmortem diagnosis in a 53-year-old male patient, without known his pathological history, who was a victim of sudden death from abdominal pain. The autopsy revealed diffuse atheromatous cardiac, aortic, and hepatic lesions.

Conclusion: It is very common for myocardial steatosis to be diagnosed postmortem due to its nonspecific symptomatology. The risk of mortality and morbidity could be reduced through a healthy lifestyle and regular biological examination to identify risk factors.

Authors: Chirillano Lucio Alfonso , D’Agostino de Salazar Paola Gisele , De la Sota Pablo Elías , Etcheverry Marta Cecilia , De Candia Cristian Ariel
Published: April 2023

Introducción: El aumento en la sensibilidad de las técnicas empleadas ha permitido la obtención de perfiles genéticos a partir de trazas de ADN que se hayan depositado mediante contacto antes, durante o después de la comisión de los hechos investigados. Por otro lado, la contaminación accidental de los indicios biológicos, con la consecuente interpretación errónea de los resultados genéticos, tienen importantes consecuencias en el proceso judicial. Debido a ello, minimizar las contaminaciones que se pueden generar durante algunas de las fases de recolección o análisis genético, como así también la detección de estos eventos, es una prioridad para los laboratorios forenses. Objetivo: analizar las publicaciones más relevantes respecto a las trazas de ADN, los diferentes tipos de transferencia y contaminación que se pueden obtener en una evidencia. Metodología: se realizó la búsqueda en PubMed, del Instituto Nacional de Salud (NIH), y Google Académico usando las palabras clave en español e inglés: ADN de toque, Transferencia de ADN, Contaminación, Trazas, DNA-TTPR, Persistencia del ADN, Perfiles genéticos contaminados. Resultados: se encontraron más de 500 trabajos relacionados a la temática propuesta en esta revisión. El criterio de selección fue el número de citas, el enfoque y el impacto de estos. Se analizaron 71 artículos donde evaluaron la composición de las muestras de contacto y el origen del material genético que contienen. Además, de las metodologías de recolección, análisis de dichas muestras, la importancia que tiene la transferencia y contaminación del ADN en distintos escenarios posibles. Conclusión: existe riesgo de transferencia de ADN que puede conducir a resultados erróneos, por lo tanto es importante asegurar la actualización de los procedimientos de la práctica y brindar la capacitación adecuada para garantizar que el personal policial y del que recolecta indicios sea consciente de los riesgos de contaminación y de los diferentes mecanismos de transferencia de material genético.

Authors: Robles González Yurby Lailiny , Ussa Pérez Diego Alejandro , Del Valle Useche Carlos Miguel
Published: April 2023

Justificación: En Colombia, el comercio de especies de fauna silvestre sin la documentación necesaria es prohibido por ley, por lo que, en el contexto de una investigación penal sobre venta de reptiles a través de internet, como parte de una diligencia de allanamiento y registro, se realizó el procesamiento del lugar de los hechos. Objetivo: realizar la asignación taxonómica más probable utilizando análisis genético en muestras biológicas recolectadas del lugar de los hechos para establecer la presencia de reptiles, dada la ausencia de animales en el momento del allanamiento. Métodos: se recolectaron seis muestras biológicas que incluyeron un trozo de muda de piel, hisopados de superficies y materia fecal, para su posterior procesamiento siguiendo los protocolos de análisis establecidos. Se realizó extracción de ADN empleando sílice y se amplificó un marcador mitocondrial 12S-120pb; los fragmentos resultantes fueron secuenciados y las secuencias fueron comparadas con la información disponible en la base de datos Genbank mediante el algoritmo BLASTn. Resultados y discusión: a partir de los datos obtenidos de la comparación realizada, 100% de cobertura y 100% de identidad y tras analizar las características de cada grupo taxonómico y la información genética disponible se realizó la asignación taxonómica. En la muestra de muda de piel se encontró dificultad para la amplificación y secuenciación de todo el fragmento, lo que limitó el empleo de marcadores de mayor tamaño, sin embargo, a partir de la información obtenida se logró la identificación de la especie Boa constrictor (boa común); en el caso de la materia fecal y los hisopados se determinó la presencia de muestras provenientes de grupos taxonómicos comúnmente empleados para alimentación de algunas especies de reptiles, como Mus musculus (ratón común) y el género Rattus (especies de ratas). Conclusión: El marcador mitocondrial 12S-120pb empleado en este caso resultó exitoso para la obtención de secuencias a partir de muestras forenses, sin embargo, la utilización de cualquier marcador para la asignación taxonómica depende en gran medida de la información disponible y las características propias de cada grupo taxonómico.

Share Cross-ownership Regulation and Stock Process: Evidence from the Chinese Market and Recommendations for Philippine and Vietnamese Law
Authors: Tran Nguyen Phuoc Thong
Published: April 2023

Cross-shareholding promotes price synchronization and reduces price lag. More importantly, this effect on price informativeness is evident for large companies and during market downturns. In general, the relationship between cross-ownership structure and stock price informativeness exists clearly. This paper investigates the impact of share cross-ownership on stock prices as a measure of price informativeness from companies listed on the Chinese stock exchange. The paper has learned an overview of cross-ownership and the stock market in China through jurisprudence analysis and comparative jurisprudence method. At the same time, the author also discusses the positive effects of regulation and cross-ownership structure on stock prices to better understand the relationship between cross-ownership and price dynamics through the impact of cross-ownership on the information environment. A notable point that the paper also discusses is the advantages of symmetric cross-ownership compared to the process of merger of joint stock companies to determine the balance between market efficiency and the social welfare loss brought about by symmetrical cross-ownership. From there, the paper will evaluate the influence of cross-ownership in Vietnamese and Philippine laws through agency theory and corporate governance models. Finally, make some recommendations for Philippine and Vietnamese laws.

Published: April 2023

Background
Today, repair techniques almost completely take place of the mitral valve replacement, especially in patients with degenerative disease. Majority of the surgeons hesitate to prefer repair in patients with bileaflet prolapse. In this study we aimed to investigate postoperative results of our patients with mitral valve insufficiency due to bileaflet prolapse and treated with repair techniques

Methods
89 patients who underwent mitral valve repair by the same surgical team due to bileaflet prolapse, between January 2006 and January 2016 in Turkiye Yuksek Ihtisas Hospital were included to this study. Preoperative, operative and postoperative data such as mortality, recurrent mitral insufficiency, echocardiographic parameters and reoperation rates were investigated.

Results
Mean follow up duration was 25.3±17.7 months. Mean age was 46.6±17.4 years. According to the transthoracic echocardiographic evaluations, 8 (9%) patients had moderate and 81 (91%) patients had severe mitral insufficiency. When preoperative and postoperative values were compared statistically significant improvement in functional capacity of patients according to NYHA classification has been noted. (2.1±0.5 ; 1, , p=0.001) Improvements in left ventricular end diastolic diameter (5.5±0.7 cm ; 5±0.6 cm, p=0.001), left ventricular end sistolic diameter (3.8±0.6 cm ; 3.6±0.6 cm, p=0.004 ), left atrium diameter (4.8±0.9 cm ; 4.3±0.6 cm, p=0.001) and pulmonary artery pressure (44.3±13.4 mmHg; 32.1±5.4 mmHg, p=0.001) were statistically significant.
Conclusions
In the lights of findings about good postoperative results and durability rates, mitral valve repair can be safely used in patients with mitral valve insufficiency due to bileaflet prolapse especially with chordae replacement technique which can be feasible after improvements in suture technologies.
Apigenin-7-Glucoside Attenuates Hydrogen Peroxide-Induced Oxidative Stress and Neuronal Death in SH-SY5Y Cells Via Activation of Antioxidant Enzymes System and Inhibition of Caspases Genes Expression
Authors: GÜÇLÜ Ebru , ÇINAR AYAN İlknur
Published: April 2023

Aims: In this study, it was aimed to investigate the possible neuroprotective effect of Apigenin-7-Glycoside (AP7Glu), a natural product with known anticancer and anti-inflammatory activity, against hydrogen proxide (H2O2)-induced oxidative stress in SH-SY5Y cells.
Methods: The effect of H2O2 and AP7Glu on cell viability was determined by XTT analysis. SOD and catalase analyzes were performed to determine antioxidant enzyme activities. Expression levels of antioxidant defense system related genes and caspase genes were evaluated by qRT-PCR analysis.
Results: After treatment of 300 µM H2O2 to SH-SY5Y cells for 24 hours, cell viability was determined as 63.18% and this dose was used to induce oxidative stress. H2O2 treatment in the presence of different concentrations of AP7Glu increased cell viability compared to H2O2-treated cells. And, H2O2 decreased SOD and catalase enzyme activities compared to control group. With the treatment of H2O2 in the presence of AP7Glu, an increase was observed in these enzymes activities compared to H2O2-treated cells. In addition, H2O2 decreased the expression levels of genes associated with antioxidant defense system and increased expression levels of Caspase genes. And, H2O2 treatment in the presence of AP7Glu increased the expression levels of genes associated with antioxidant defense system and decreased CASP8 expression compared to H2O2-treated cells.

Abstract

Background: Visceral organ blood circulation is seriously impaired in aortic pathologies especially aortic dissection involving descending thoracic and abdominal aorta. Herein, we aimed to determine the effect of the newly onset renal function impairment on postoperative mortality rates of the patients undergoing EVAR and TEVAR procedures.

Methods: Patients who underwent an EVAR / TEVAR procedure in our clinic included in this retrospective study. Patients were divided into two groups according to the presence of renal function impairment. Mortality rates were calculated for the groups.

Results: A total of 60 patients who underwent an EVAR/TEVAR procedure between November 2016 and May 2021 included in this study. Group 1 included a number of 48 (80%) patients without postoperative renal dysfunction. Group 2 included a total of 12 (20%) patients with postoperative renal function impairment. The initial analysis of the data revealed significant differences in the age and sex variables of the groups (P=0.038 and P=0.008 respectively). Then propensity score matching was performed to avoid bias in the groups. After propensity score matching Group 1 included 12 (50%) patients without postoperative renal impairment and Group 2 included 12 (50%) patients with postoperative renal dysfunction. There were no significant differences between the groups after propensity matching. Mortality rate was significantly different between the groups which was 1 patient (8.33%) in Group 1 vs 6 (50.00%) patients in Group 2 (P=0.020).

Conclusions: Renal functions after EVAR/TEVAR procedures should be carefully monitored because renal impairment is closely related with postoperative mortality. We suggest that more studies with larger patient numbers should be conducted on the relation of renal functions and mortality after regularly performed EVAR/TEVAR procedures.
An Assessment of the Content, Readability, and Reliability of Turkish Websites That Provide Information About Facial Paralysis
Authors: SALBAŞ Ender
Published: April 2023

Background/Aims:
Known as Bell's palsy, is a neurological disorder characterized by partial or complete paralysis of the muscles of the face, results from impairment or dysfunction of the facial nerve. This study aims to evaluate the readability, content, and quality and determine the level of accuracy and reliability of websites in Turkish language that provide information about facial paralysis.
Methods:
This descriptive, cross-sectional study analyzed the quality, usability, content and readability of Turkish facial paralysis websites using the Ateşman and Bezirci-Yılmaz Readability Formula, reading time, number of images, JAMA Benchmark Criteria, DISCERN Scale and UpToDate topics. Webscore.ai was used to assess aesthetic appeal and user experience.
Results:
After reviewing 200 websites, 110 Turkish sites about facial paralysis were included in the study. Average reading time was 5.5 minutes. Bezirci-Yılmaz score was 13.8. Ateşman readability levels were moderate. News, blog and "other" sites had the most visual content, followed by Health Professionals (HP) sites. Average quality of sites was poor.
Conclusions:
The DISCERN scale found 60% of Turkish health websites had poor-to-very poor content quality. UpToDate's benchmarking revealed 58.2% of sites contained less than half of the basic topics. This indicates inadequate, outdated info for facial paralysis patients. State Institutions and Health Related Associations should provide valid, reliable info on modern websites.

ABSTRACT
Aim: Twin pregnancies are associated with increased perinatal mortality and morbidity compared with singleton pregnancies. Single intrauterine fetal death (sIUFD) is difficult to treat. This is because the twin who survives after sIUFD is at high risk for mortality, neurological damage, and other complications of preterm birth. Therefore, in this study, we aimed to determine the perinatal consequences for the surviving fetus. We also investigated the association between chorionicity, maternal characteristics, and fetal and maternal concomitant complications in these cases.
Methods: We conducted a retrospective case-control observational study that included twin births complicated by sIUFD followed up in the Department of Perinatology. Data, including demographic characteristics and prenatal invasive procedures, weeks of sIUFD, delivery time, fetal sex, interval between delivery and fetal loss, fetal distress, mode of delivery, birth weight, presence of placental pathology or umbilical cord abnormalities, neonatal Apgar scores in the first and fifth minutes, and need for neonatal intensive care unit (NICU), were obtained from obstetric records and hospital database.
Results: Fifty-three twin pregnancies with a single fetal death were included in the study. The mean age of the pregnants participating in the study was 30 (± 6) years. The mean body mass index (BMI) of the mother was 28.8 (22-43). Twenty-four (45.3%) cases were dichorionic (DC) diamniotic, 20 (37.7%) were monochorionic (MC) diamniotic, and 9 (17%) were monochorionic monoamniotic. The time between IUFD and birth of the live twin was 75 days in MCs and 105 days in DCs (p=0.150). The mean gestational age at birth of the surviving twin was 30 weeks’ gestation in MCs and 34 weeks’ gestation in DCs (p=0.030). In 23 (79.3%) MC pregnancies and 15 (62.5%) DC pregnancies, delivery occurred before 37 weeks (p=0.176). In addition, deliveries before 34 weeks occurred more frequently in 19 (65.5%) of MC pregnancies than in 8 (33.3%) of DC pregnancies (p=0.020).
Conclusion: We have shown that the birth of the live fetus in the MC group occurred at a significantly earlier time, and mortality and morbidity were observed more frequently in this fetus. However, this research explaining the etiology of sIUFD is insufficient.

Published: April 2023

Aim: This descriptive study investigated smartphone addiction and daytime sleepiness in adolescents during the COVID-19 pandemic.
Methods: The sample consisted of 1001 adolescents living in the Central Anatolia Region of Turkey. Data were collected using a sociodemographic characteristics questionnaire, the Cleveland Adolescent Sleepiness Questionnaire (CASQ), and the Smartphone Addiction Scale-Short Version (for Adolescents) (SAS-SV). The data were analyzed using descriptive, comparative, and correlational statistics.
Results: Most participants stated that they had spent much more time on their smartphones since the pandemic (87.2%). More than half of the participants noted that they had been on their smartphones for more than 90 minutes daily (63.1%). Less than half of the participants said they spent most of their time on Instagram (44.8%). More than half of the participants reported daytime sleepiness (55.7%). Less than half of the participants had a moderate-level sleep status (44.8%). There was a positive correlation between CASQ “sleep in school” and “sleep in the evening” subscale scores.
Conclusion: During the COVID-19 pandemic, adolescents are at high risk of smartphone addiction, affecting daytime sleepiness. Therefore, we need interventions to reduce the risk of psychological problems and daytime sleepiness in adolescents.

Informing as National Indifference? The Case of Finnish Citizens’ Collaboration with the Russian Authorities, 1899–1917
Authors: Suodenjoki Sami
Published: April 2023

Between 1899 and 1917, hundreds of Finnish citizens approached the Russian authorities with letters of denunciation, in which they reported about the anti-government activity of their fellow citizens. These informers caused a public stir in Finland because their activity was associated with the intensifying political surveillance of the imperial security police. Finnish nationalists eagerly labeled informers as Russian-minded traitors, but how did the informers themselves relate to the nation and the empire? This article tackles this question by analyzing the communication of these citizens with the Governor General's Office and the Gendarme Administration and by drawing inspiration from the concept of national indifference, which has gained prominence in nationalism studies in recent years. The article shows the great variation with which informers framed their ideological stance in their letters to the imperial power. Some avoided referring to their Finnishness to emphasize their imperial loyalty, whereas others presented themselves as pro-Finnish and viewed the interests of Finland and Russia as uniform. As a distinctive group of informers, the article examines Orthodox people, whose letters to the imperial authorities highlight experiences of religious discrimination and consequent national ambivalence.

At this time in the era of cars that use renewable energy fuels such as electric cars which are highly supported by the government so that it has an impact on used cars based on these problems an analysis is needed. Determining whether or not the price of buying or selling a used car is appropriate is one of the obstacles faced by the community in making decisions when buying or selling a car or vehicle. Therefore, most people choose an alternative by buying a used car that is still good and usable. One way to make price predictions is to use the Machine Learning method. In this study the authors used random forest and decision tree methods to predict car prices. The results of the research on car price prediction analysis using the random forest and decision tree methods have different percentage results. Where using the random forest method there is an accuracy: 72.13% whereas with the analysis of the decision tree method accuracy: 67.21%. So it can be concluded that the Random Forest method has better analytical accuracy than the Decision Tree method.
