Published: October 2022

Abstract
In order to improve the quality of wireless English multimedia communication, according to the characteristics of space multimedia communication environment and communication equipment, this paper proposes a wireless English synchronous QoS control algorithm with low complexity and easy implementation. Using RTCPSRRTP timestamp and NTP absolute timestamp, the wireless English RTP timestamp is mapped to the same absolute reference clock (sender system time) respectively, and the wireless English synchronization detection decision rule is established according to the synchronization QoS performance requirements between wireless English media. Wireless English synchronization control system model at the receiver. At the receiving end, the wireless English stream is the main media stream and the video stream is the slave media stream. The synchronization detection and judgment is implemented in real time before the video frame is played. The synchronization between audio and video media is realized by corresponding synchronization control of wireless English playback. State space model reflects all the information of system dynamic behavior and is a complete description of system behavior. The state space model has a wide range of applications. It is not only suitable for SISO linear constant systems, but also suitable for nonlinear systems, time-varying systems, MIMO systems and stochastic systems. The more outstanding advantage is that the state space model adopts local calculation and uses the state variables inside the system to describe its dynamic characteristics. This property of local calculation not only greatly simplifies the mathematical expression of multi-dimensional system, but also facilitates the analysis and research of the system. The air link rate of the wireless transceiver is set to 512Kbps. The video is encoded based on H.264 and the audio is encoded based on G.729 Speech coding standard. Compared with the wireless English media synchronization control algorithm based on RTP / RTCP, the results show that the RMSE value after adopting the synchronization algorithm in this paper is reduced by 60.09% and 77.69% at most; Compared with the wireless English media synchronization control algorithm based on RTP / RTCP, the synchronization performance of this algorithm is better than the wireless English media synchronization control algorithm. The RMSE value is reduced by 2% on average and 5.2% at most. In addition, the synchronization control algorithm between wireless English media performs synchronization control by losing frames or pausing decoding before video decoding at the receiver, which affects the quality of wireless English video decoding and reconstruction.

Abstract
Multi-core processor is a new type of parallel nonlinear function. It has the characteristics of high efficiency, low power consumption and scalability. It has applications in several fields, such as industrial environments, military weapons systems, aerospace technology, and biomedicine. The core function of a multicore processor is an algorithm that can realize the expansion of the capacity of the isoparametric center and the lifting space, whose main idea is to optimize the spatial distribution by changing the input vector. Traditional solution methods generally use iterative or variational methods to solve nonlinear programming problems, but linear algebraic function models are widely used because of their simplicity and ease of numerical computation. The discrete and multi-attribute matrix combination algorithm can be used to realize the process of transforming complex problems into easier solutions. This paper introduces the basic concepts of linear programming and conducts simulation experiments with a multicore processor, and then makes improvements to a typical optimization problem. This paper analyzes the mathematical principles and steps of the nonlinear mapping algorithm; then MATLAB is used as a platform to study the design process of the multicore set-driven function. Finally it verifies that the method is feasible in solving complex models by arithmetic examples.

Authors: Yue Ya 
Published: October 2022

Abstract
An algorithm is proposed to derive the quadratic wave equation and to generate a musical theme based on the basic frequency differentiation of singing. The algorithm can effectively reduce the false alarm speed of the melody localization and improve the overall accuracy. The Metric Distance (DIS) algorithm uses the dispersion method to segment musical notes and to detect vocal parts; The amplitude compression frequency filter (PEFAC) uses multi-frequency frequency separation technology. vocal range by calculating the melody. Basic frequency of multiple candidates. Finally, the Viterbi algorithm is used to control the predominant basic frequency trajectory of the vocal segment and is used to distinguish the basic melody of the basic frequency differentiation model. Tests on the MIR-1K data set show that all performance parameters of the improved algorithm are higher than the original algorithm, tone localization call speed (VRR), initial sound frequency accuracy (RPA), and initial color accuracy level (RCA). ) and the Total Accuracy Level (OA) improved by different signal and interference conditions, while the pseudo-localization (VFAR) decreased by about 2%, indicating that the improved algorithm could more accurately identify the accompaniment and vocals. This is because the accuracy of recognizing the basic frequency discrimination model in an improved algorithm is higher than in the original algorithm. In addition, the AET of the improved algorithm is reduced by approximately 0.12 seconds compared to the original algorithm, which ensures that the process calculation and complexity of the frequency function function of the improved algorithm is lower than that of the original algorithm. The octave error detection, the false localization signal is much lower than other algorithms, and the overall accuracy level is higher than other algorithms, which can effectively produce the basic melody of the song.
Implementation of the Rules of Good Practice in Transfusion Activity at the Level of the Blood Transfusion Unit of SCJU Constanta
Authors: Teodora-Luiza Stancu , Leonard Gurgas 
Published: October 2022

Abstract
Introduction. Blood is a vital resource, and its use is growing worldwide. Although the demand for blood is high, there are cases in which blood products are rejected. The number of rejected blood components in hospitals is reported to be between 0.1% and 6.7%. (1–5)
Objectives. Quality management includes good practices in transfusion activity, an important part of which is limiting the rejection of labile blood products. The objective of this study is to analyze the use and rejection of blood products in the Constanza County Emergency Clinical Hospital between 2012–2021, including 2 years of the Covid-19 pandemic.
Material and method. The work presents a retrospective study of transfusion activity over a period of 10 years, with the analysis of units of labile blood products rejected compared to the number of units transfused to hospitalized patients.
Results and discussions. In our institution, with a large number of transfused patients and a very large volume of administered blood products, the rejection was on average 1.82% (3,887 rejected products out of the 213,869 received products). Most rejected products were erythrocyte concentrates (1491 units). The good practice measures implemented have led to a decrease of the number of rejected products, with a reduction of the number of rejected units in the last 3 years by an average of 142 units per year.
Conclusions. Quality assurance is a legal obligation in the transfusion sector. The implementation of the norms of good practice according to the Order M.S. no.329 / 2018 led to the decrease of the number of rejected products from 2.81% in 2018 to 1.16% in 2021. An increasingly restrictive blood test is used.

Abstract
The World Health Organization (WHO) declares COVID 19 pandemic in March 2020. Each pandemic wave had different clinical and biological characteristics, the expression of the disease being correlated with the dominant viral variant. Patients with COVID 19 have a pro-coagulant status, which predisposes them to thromboembolic complications.
The current study aims to systematize the symptoms of COVID 19 and to highlight its relationship with the suspicion and confirmation of the diagnosis of pulmonary thromboembolism.
We performed a descriptive retrospective study on patients with COVID 19 for a period of 4 months (September-December 2021). During this period, 183 were hospitalized with COVID 19 and 53 were enrolled in the study. Incidence of COVID 19 was 63% (33) in men and 37% for women. The average age of women was 68 years compared to men where the average age was 61 years. We observed a higher incidence of the disease in men in the 41–60 age group (39% of all men), while, in women, the most affected age group was 61–80 years (60% of all women). Pulmonary thromboembolism (PE) was diagnosed by pulmonary artery angiography, with an incidence of 57% in the study group affecting 60% of women and 55% of men.
The symptoms are dominated by fever, cough and dyspnea. Fever was present in 65% of women and 55% of men, cough was present in 65% of women and 79% of men, while dyspnea involved 40% of women and 42% of men.
In conclusion, PE was a common complication in COVID patients that contributed to adverse outcome and higher mortality. The symptoms were not specific to minor forms of the disease.

Abstract
First described by Bright in 1836, who reports two cases secondary to suppurative angiocolitis and pilephlebitis, intrahepatic suppurations were, until the era of the discovery of antibiotics, one of the most dreaded causes of mortality, reaching a rate of almost 100%. Today, both the incidence of liver abscesses and the mortality rate have been significantly reduced, as the introduction of antibiotics has dramatically reduced the number of septic piles due to peritoneal outbreaks. Their etiology is more recently, most frequently, a biliary or neoplastic disease. On the other hand, the improvement of germ isolation techniques has made it possible to identify anaerobic germs with maximum frequency, and diagnostic and treatment performance has increased so much with the advent of non-invasive or minimally-invasive procedures that the overall mortality rate of 70% in 1975 is now about 30–38%.
We present the case of a 75-year-old male patient with no known history of ilnesses who is admitted for fever, chills, myalgia, arthralgia and visual disturbances with onset of approximately one week. Biologically he presents with leukocytosis with marked neutrophilia, mild thrombocytopenia and significant biological inflammatory syndrome. Suspicion is raised for a diagnosis of Sepsis with unspecified starting point with possible pyogenic cavernous sinus thrombosis, a complication suggested by the presence of visual disturbances. Neuro-imaging evaluation by CT and brain MRI is performed, with the diagnosis of thrombosis being refuted. Abdominal CT is performed which identifies a space replacement formation in the left hepatic lobe for which MRI evaluation is required. MRI detects an expansive hepatic formation with semiology suggestive of liver abscess. Treatment was instituted with a combination of broad-spectrum antibiotics and antifungal treatment, but the evolution was unfavourable with maintenance of leukocytosis with marked neutrophilia and progression of inflammatory samples. It was necessary to evaluate the case by a multidisciplinary team (infectious disease specialist, gastroenterologist, surgeon) to establish the appropriate therapeutic management, with surgical resolution of the case, with a favourable postoperative evolution.
HMGB1-RAGE, A Useful Partnership in Vital Response?

Published: October 2022

Abstract
Introduction: In forensic practice, it is well known that the mechanism and dating of traumatic injuries is one of the primary responsibilities of this specialty. Currently, it is a subject still debated by researchers, and so far, an infallible marker that would objectively support their intravitam/postmortem occurrence has not yet been identified. However, studies have shown that the HMGB1-RAGE axis is rapidly activated after trauma and might be an essential element to help solve the forensic problem of wound dating.
Purpose: To compare the values of HMGB1-RAGE expression occurring in wounds produced intravitally shortly before death and in wounds produced postmortem and to quantify the differences arising between them.
Material and method: For this prospective study, skin fragments were collected from the site of wounds in autopsied cadavers at the County Clinical Service of Forensic Medicine Constanta (SCJML Constanta), wounds produced intravitally and with a maximum survival time of 60 minutes. Postmortem wounds and control fragments from volunteers undergoing surgery for skin tumours were also collected. The main conditions were: chronological documentation of the lesion and absence of neoplastic or inflammatory conditions. Ninety-six autopsy cases between 2021–2022 met the criteria for inclusion in the study. A control fragment accompanied each fragment from the wound. Routine Hematoxylin-Eosin (HE), Perls and Van Gieson Werhoeffstaining, as well as immunohistochemistry with HMGB1 and RAGE markers were performed on each fragment and a score based on staining intensity was determined.
Results: Routine staining was not useful in assessing vitality in segments with survival time up to 30 min. Immunohistochemically, both markers showed increased values compared to control values (p<0.0001) and to lesions produced postmortem. An interesting aspect is the lack of reactivity in the lesion’s margins for both markers.
Conclusions: Although further research is needed, the results of our study support the hypothesis that the HMGB1-RAGE axis is useful in assessing the vital reaction in skin wounds.

Abstract
Liver cirrhosis is the common final pathway of many diseases and is the third leading cause of mortality. Biochemical and cytological data, together with imaging data interpreted in the context of clinical data, have an important weight in formulating the diagnosis, establishing the prognosis and controlling the therapy.
We have carried out a comparative biochemical and cytological study of the blood serum and ascites fl uid from 30 patients with liver cirrhosis aged between 35–70 years admitted to the medical and surgical wards 1 of Constanța County Clinical Hospital, the study was carried out over a period of one year, the analyzes were performed in the Biomedical laboratory.
We correlated the following biochemical parameters in these patients: albumin, LDH, TGO, TGP, total bilirubin, from the blood serum, the INR from the plasma and those that can be dosed in the ascites fl uid, as well as the cytological aspects, in order to detect the malignant transformation of liver cirrhosis in view of the early establishment of an appropriate treatment.

Abstract
Introduction: Abdominal cystic lesions can be localized either in parenchymal or non-parenchymal organs and can be acquired or congenital. Knowing the characteristic imaging features as well as demographic data and the prevalence of cystic lesions can help radiologists in establishing the correct diagnosis. In this article, we conducted a statistical study of congenital and acquired cystic lesions of the abdomen, diagnosed by CT scan in patients hospitalized in Emergency Clinical County Hospital of Constanţa in years 2019 - 2020.
Material and methods: The retrospective study included 285 patients admitted to the hospital. In the case of each patient, we recorded the following variables: Age, Sex, Localization of the lesion, Types of cysts for each localization.
Results: The average age of the patients is 61.53 years. Most of the cystic lesions were localized in the liver (182 cases) and they were represented by: hydatid cysts, simple hepatic cysts, hepatic abscess, hepato-renal polycystic disease and hepatic adenocarcinoma. Cystic lesions of the kidney (56 cases) were represented by: autosomal dominant polycystic kidney disease, renal carcinoma, simple renal cysts, acquired polycystic renal disease, tuberous sclerosis, clear cell renal carcinoma and von Hippel Lindau syndrome. Cystic lesions of pancreas (47 cases) were represented by: pancreatic cysts, pancreatic pseudocysts and pancreatic adenocarcinoma.
Conclusions: CT examination is extremely useful in establishing the location, type, imaging characteristics of cystic lesions, echo over surrounding organs, possibility of malignant transformation. The prevalence of certain types of localizations and morphologies depending on the age and organ involved always helps to obtain a correct and rapid diagnosis.

The Structure of Ideas: Problems for Thinking about the Pure Ego
Authors: Martín Javier San 
Published: October 2022

Abstract
In the first part of my paper, we will journey through the general structure of the first volume of Ideas, from which we will be able to deduce the position of Volume II. After carrying out a general analysis of the noesis/noema correlation structure in Section III and having provided, in Section IV, the basics of a phenomenology of reason, the second volume of Ideas should study the general fields in which the objects of transcendental experience appear: the world, the animal being, and the spiritual or cultural being. The third, unwritten volume should have been devoted to the study of the superior products of culture, and science. Thus, the second part of this paper will show the place of Ideas’ second volume. The third part, the decisive one, will inquire into the position of the world and the place of the body and culture. Specifically, it will ask whether the experience of the body is understood to be an objective genitive or whether it is also understood, necessarily, as a subjective genitive. The same question will be asked about culture. An understanding of one as objective or subjective genitive radically alters the meaning of the pure ego.
Description, Reflection, Reduction
Authors: Renaudie Pierre-Jean 
Published: October 2022

Abstract
This article analyses the fundamental relationship between Husserl’s theory of reflection in the first volume of Ideas pertaining to a pure phenomenology and the two main concepts upon which transcendental phenomenology is grounded: namely, description and reduction. Although the concept of reflection was already used in Logical Investigations, Husserl revised it entirely thanks to his analysis of time-consciousness in the 1905 Lectures. Reflection thus appears as a key concept in understanding the ‘turn’ that led Husserl to deeply modify his descriptive method in order to move to transcendental phenomenology.

Abstract
In this study, the issue of economic growth and Convergence in the 12 countries of the CIS region has been investigated thoroughly for 27 years, from 1991–2017. The paper examines the absolute, sigma and conditional Convergence of the CIS region. Conditional Convergence is examined through the augmented Solow and extended Solow models. During the study period, the empirical results confirm no significant negative correlation between the initial ratio of the countries per capita GDP and the average yearly growth rate. Thus, indicating the absence of absolute β convergence across the CIS economies during 1991–2017. The results of the sigma convergence are consistent with the results derived from the absolute convergence model. Referring to the augmented Solow model estimations, we found the rate of conditional β-convergence (coefficient of initial GDP per capita) of value 0.028 among members of the CIS region after controlling GDP per capita, physical and human capital and population growth have important contributions to make in the growth and Convergence of countries. In Solow extended growth regression, the initial GDP per capita coefficient is 0.33. Therefore, besides the initial level of per capita income, physical and human capital and population growth, other factors have important contributions to make to the growth and Convergence of countries of CIS.
