Introduction. Despite the genetic counseling, families with cystic fibrosis (CF) patients and modern possibilities of prenatal molecular genetic screening, the occurrence of CF in more than one child in a family is not rare. The same genotype is expected to determine the specific phenotype in CF patients, especially in siblings. However, broad clinical heterogeneity could indicate the influence of secondary genetic factors on the course of the disease.

The aim of the study is to examine the genotype-phenotype correlation and disease course features in CF siblings, including twins.

Materials and methods. A clinical retrospective cohort observational study included fifty three sibs (23 boys, 30 girls) aged from 6 months to 17 years 9 months (median age of 8.3 (4.8–12.9) years, age difference 5 ± 2 years) with a diagnosis of CF confirmed by molecular genetic methods. Group 1 consisted of 9 twin pairs (3 — monozygotic, 6 — dizygotic), group 2 — 35 complete sibs.

Results. The mean age of diagnosis for older sibs is 2.5 years (8 months — 9,8 years; min — 1 months, max — 17 years) and for younger sibs — 8.5 months (1.3 months–3 years). Chronologically, the onset of CF was registered earlier in younger sibs than in older sibs in 3 (16.7%). In 6 (22.2%) of families, the pancreatic status of sibs varied from normal function to severe pancreatic insufficiency, with the occurrence of pancreatitis observed in only 4 (7.6%) patients. In 21 (77.8%) families with sibs infected by P.aeruginosa, 5 (23.8%) had a simultaneous primary culture of the pathogen, 8 (38,1%) had culture in both children but with an interval from 1 month to 9.5 years (Ме: 3.2 (5 months–4.9 years), and in 8 (38.1%) had culture in only 1 sibling. All younger sibs had the primary contamination at an earlier age with a 5.3 year (2–6.6 years;) difference. In 10 (37.0%) of the families, the pulmonary function of the sibs was variable. The number of bronchopulmonary exacerbations per year ranged in 8 (29.6%) of sib pairs and averaged 1.3 ± 0.5 in older sibs, 1.1 ± 0.3 in younger sibs, and 1.7 ± 1.3 in twins. The severity of hepatic involvement varied in 9 (33.3%) of sib pairs: no morbidity in 6 (33.3%), cystic fibrosis-associated fibrosis in 7 (38.9%), and cirrhosis with portal hypertension in 5 (27.8%).

Conclusion. CF siblings, despite the same genotype, similar environmental conditions, and high risk of cross-infection, are characterized by wide phenotypic heterogeneity. Aside from the pathogenic CFTR variants, there are other genetic (modifier genes) and epigenetic (microRNA, DNA methylation) factors that could contribute to the clinical features of cystic fibrosis.

Published: August 2023

In recent times, Diabetic Retinopathy (DR) has emerged as a critical complication for patients with diabetes, where the blood vessels in the retina are severely damaged, potentially leading to vision loss and, if left untreated, blindness. The World Health Organization has projected that by 2040, DR will impact around 224 million people. To address this issue, this research paper proposes CNN Wide-Net-X architecture model for image classification, which utilizes colour fundus images to detect Diabetic Retinopathy. The objective of this model is to enhance the accuracy and efficiency of the diagnostic process. For training and testing the model, the EyePACS dataset consisting of 5220 images is utilized, which is a widely accepted dataset for detecting Diabetic Retinopathy. To evaluate the performance of our model, we use metrics such as accuracy, precision, recall, and F1-score. The proposed CNN model is a significant step towards early detection and accurate diagnosis of DR. It is hoped that with the increased accuracy and efficiency provided by this model, patients with DR can receive timely treatment, thereby reducing the risk of vision loss and blindness.

Authors: Al-Paruany Kamal B. , Al-Naseri Saadi , Al-Ajena Al-Hassen F.
Published: August 2023

The environmental isotopes composition of water (δ18O, δ2Hand 3H) and hydrochemistry concentration were measured seasonally at eight stations along Euphrates River within the study area for two periods (January–Augustm, 2014) to study temporal special variations of these isotopes. The results of isotopes values showed there is a little difference between the periods due to the seasonal change and the trend of distribution can be attributed to evaporation and drainage flow. Generally the river water has positive d-excess, which indicates the vapor source of the Mediterranean moisture sources in January, while a low d-excess associated with enriched isotopic values, which typically occurs during August, 2014. The Euphrates River water, is fresh (TDS < 0.39 g/L) and has slight increase in its salinity levels during the last two decades. Generally the chemical facies changes from a calciummagnesium and bicarbonate type towards a sodium-chloride type to calcium sulfate. River salinity increases according to rock type, lake water, evaporation and human activity, and relatively higher toward downstream stations. The absence of management and a working drainage system, together with irrigation under high evaporation rates and low discharge, are the primary reasons for the continuous deterioration of water quality.

Nowadays currently, many people are found using language that sometimes runs away from the standard or changes from the standard. They use language only based on their desires. These language changes give the impression of making readers or the public may be confused to understand the true meaning. This makes researchers interested in discussing this issue. This study will focus on the exploration of language change that occurs in social media nowadays. The authors will draw inspiration from various texts on social media. The researchers will complete the survey and the study using Internet facilities. This study was conducted qualitatively and the writers will also be observing the language change directly from the relevant social media applications. The information gathered is terminological in nature, replete with human characteristics, and based on captions from several social media platforms including Twitter, Instagram, YouTube, and Facebook. Following the completion of this study, the researcher discovered that the vocabulary used by social media users to connect with one another had changed. After the researcher analyzed the data obtained, the researcher found that the semantic change was the biggest change that had been found. As much as 32% of language changes occur in social media and this illustrates that quite a lot of social media users do not use meanings that are not following their standards. Researchers also found that 10% of language changes occurred in the field of morphology. This illustrates that a few social media users result in language changes in the syntax field

Antecedentes: la tiña de la cabeza (tinea capitis) es una dermatofitosis del cuero cabelludo causada por hongos dermatofitos; los más frecuentes son Microsporum canis y Trichophyton rubrum. En el transcurso del último año se ha informado un incremento en la incidencia de Trichophyton tonsurans en personas que acuden a las barberías.

Objetivo: se planteó evaluar retrospectivamente las historias clínicas de los pacientes con sospecha de “tiña de las barberías”.

Diseño: se realizó un estudio retrospectivo que incluyó los casos evaluados durante un año, desde agosto de 2021 hasta agosto de 2022, de pacientes con tiña de la cabeza que consultaron a distintos centros en la Ciudad Autónoma de Buenos Aires.

Materiales y métodos: se recolectó información de 37 pacientes que consultaron durante un año por cuadros compatibles con tiña de la cabeza. Se tomaron muestras para examen directo y cultivo para hongos.

Resultados: 21 pacientes fueron evaluados en el Hospital Alemán, 15 pacientes en el Hospital Ramos Mejía y 1 en el Hospital Tornú. En 27 casos los cultivos fueron positivos para Trichophyton tonsurans, 1 fue positivo para Trichophyton rubrum, 14 fueron negativos y 1 no realizó el estudio. De los 27 pacientes que acudían a barberías o tenían contacto estrecho con personas que lo hacían, 22 tuvieron exámenes directos positivos para dermatofitos o cultivos positivos para T. tonsurans y 14 fueron negativos. Todos fueron medicados con terbinafina, con buena respuesta.

Conclusiones: la tiña de la cabeza es rara más allá de la infancia. El aumento de la incidencia de casos en adultos jóvenes y el aislamiento de T. tonsurans como germen emergente en la Ciudad Autónoma de Buenos Aires podrían relacionarse con la asistencia a las barberías.

Authors: Biasutto Magdalena , Martínez María Florencia , Angles María Valeria , Mazzuoccolo Luis Daniel
Published: August 2023

La epidermólisis ampollar es una familia de genodermatosis de baja prevalencia. Se caracteriza por la elevada fragilidad mecánica de los tejidos afectados, que da lugar a ampollas mucocutáneas, erosiones y ulceraciones de difícil tratamiento.El amplio espectro fenotípico de la enfermedad va desde un compromisoleve con afectación exclusivamente cutáneahasta los fenotipos más severos, en los que pueden afectarse tanto la piel como las mucosas, lo que la convierte en una enfermedad multisistémica discapacitante e, incluso, mortal.
Si bien se la considera un paradigma de la biología de la piel, ya que su estudio permitió avances fundamentales en la comprensión del funcionamiento de la membrana basal, hasta el momento su manejo continúa como paliativo, ya que aún no hay ningún tratamiento dirigido hacia su fisiopatología. Sin embargo, en los últimos años, la investigación en la terapia génica ha tenido importantes avances hacia futuros tratamientos que podrían cambiar la vida de los pacientes.El objetivo de este trabajo fue hacer una revisión de las novedades en los tratamientos de la epidermólisis ampollar y destacar los últimos descubrimientos.

Objetivos: estimar la frecuencia relativa de los CS y describir las características epidemiológicas, clínicas, histopatológicas y el tipo de reconstrucción quirúrgica de los pacientes con diagnóstico de CS tratados con CMM en el Servicio de Dermatología del Hospital Italiano de Buenos Aires (HIBA).
Diseño: estudio de cohorte retrospectivo.
Materiales y métodos: se revisaron las historias clínicas electrónicas (HCE) de los pacientes con diagnóstico histopatológico de CS operados con CMM entre el 1 de enero de 2010 y el 30 de abril de 2022.
Resultados: durante el período de estudio se realizaron 14.845 CMM, de las cuales 13 (0,08%) fueron por CS. El 69% de los pacientes eran varones y la media de edad fue de 70 años. La mediana de tiempo desde la aparición de la lesión hasta la biopsia fue de 6 meses. En el 61% de los pacientes el tratamiento quirúrgico se realizó en conjunto con el Servicio de Oftalmología. La mediana de seguimiento posquirúrgico fue de 14,5 meses.
Conclusiones: el CS es un tumor que se sospecha poco. En dos tercios de los casos se pensó inicialmente en otra patología, con una mediana de retraso diagnóstico de 6 meses. La CMM ofrece un control total de los márgenes de resección quirúrgica y en algunos casos se requiere la reconstrucción por oculoplastia, con un manejo integral del paciente.

The background of this research is a study that tries to explore the role of the family in encouraging the quality of learning in schools according to the concept of Ki Hadjar Deawantara  and Romo Mangun. The two ideas of educational figures that are presented in this simple work are recognized as being able to answer the challenges of implementing contemporary education which is considered to be far from the expectations of the community. Where the implementation of education is still carried out mechanically which is proven to distance students from their culture and the management of education is carried out with the principle of profit oriented (seeking profit). The type of research used in this study uses a library research approach . The data collection technique in this study is a library through written sources such as books, journals, research reports, and sources from the internet. Meanwhile, the data analysis technique used in this study is descriptive analysis. The results of this study include the following: First, Ki Hadjar Dewantara, the idea of educational thinking is oriented towards the principle of human independence, students Given freedom in recognizing its culture, and the principle of togetherness. Second, Romo Mangun, emphasized the importance of education oriented towards humanizing the implementation of education with the concept of Basic Education Dynamics (BED) and equipping small communities and groups weak to recognize his right in education. Third, the relevance of the  educational ideas of  Ki Hadjar Dewantara and Romo Mangun to the current implementation of education, namely that the current management of education runs without clear orientation and tends to be profit oriented without regard to  clear out puts. As a result, out put education cannot answer the needs of learners and relatively distances students from their culture and education can exploit  its learners. Therefore , it is important that the educational concept of Ki Hadjar Dewantara and Romo Mangun be reapplied to overcome current educational problems. The suggestions in this study are as follows : (1) The design of education policies before they are implemented must pass the socialization stage with the parents of students or the community so that the community moreover, parents of students can understand the purpose and objectives of the policy, (2) The management of learning as much as possible must involve the parents of  students such as determining the determination of strategic decisions relating to the future of learners, (3) The implementation of learning in schools should be free from discriminatory practices and forms of injustice , distancing students from their environment, (4) Cooperation between school management and parents of  students must continue to be improved so that there is synergy between schools with parents of students in improving the growth and development of  students both in the school environment and outside the school.

Precautionary measures. Conditions, seizure report
Authors: Bucur Ana Maria
Published: August 2023

The recovery of property and damage generally caused by criminal offences plays an important role in the judicial economy because imposing effective and timely measures can achieve beneficial consequences both in terms of disrupting criminal activity, reducing the capacity to carry out new criminal activities, but also in terms of strengthening society's confidence,  as a rule, on the fact that crime cannot escape control and is effectively eradicated. Lately, international cooperation at the level of competent bodies has been reflected not only in the adoption of conventions or directives in combating serious crimes such as money laundering, organized crime, terrorism or corruption, but also in the creation of mechanisms to allow the rapid transmission of information and the imposition as soon as possible of the necessary measures to block criminal benefits as soon as possible. Criminal law enforcement and criminal procedural authorities must pay particular attention to tracing, identifying and evaluating, seizing assets in order to take precautionary measures from the first moments of starting the investigation. Placing the activity of repairing damage and recovering the proceeds of crime on a secondary level and not on the same level as the activity of tracking down and catching the persons who committed the crime, inevitably leads to its failure because criminals are given the necessary time to seize their assets, after learning that their criminal activity has been discovered. Without the application of precautionary measures, any financial investigation shall be devoid of purpose unless a measure is taken to freeze the property concerned, to avoid any further disposal of property and diminution of the assets of the person who committed the offence causing damage.

Việc dự đoán phân bố nhiệt độ trong mặt đường bê tông nhựa (BTN) có ý nghĩa rất lớn cho công tác xác định cường độ và tuổi thọ của mặt đường BTN trong điều kiện thực tế. Bài báo trình bày kết quả quan trắc nhiệt độ BTN từ mô hình thực nghiệm kết cấu mặt đường mềm có lớp bê tông nhựa dày 13cm. Nhiệt độ quan trắc được sử dụng để xây dựng mô hình dự đoán phân bố nhiệt độ BTN theo phương pháp mạng nơron nhân tạo (ANN). Sau đó dữ liệu nhiệt độ tại độ sâu 4cm của BTN được ước tính từ mô hình ANN sẽ được sử dụng để phát triển mô hình hồi quy dự đoán nhiệt độ BTN tại độ sâu 4cm, phục vụ cho thí nghiệm đo độ võng đàn hồi bằng cần Benkelman. Kết quả nghiên cứu cho thấy, mô hình mạng nơron nhân tạo cho kết quả dự đoán phân bố nhiệt độ trong lớp BTN có độ chính xác rất cao với R2=0,996 và RMSE=0,582oC. Các mô hình hồi quy dự đoán nhiệt độ BTN tại độ sâu 4cm cũng cho kết quả rất khả quan, sai số RMSE giữa các mô hình hồi quy và phân tích ANN có giá trị từ 0,847 oC đến 1,367 oC tùy thuộc số lượng biến số đầu vào mà mô hình yêu cầu

Nhu cầu đỗ xe ở các đô thị Việt Nam rất lớn do giao thông phụ thuộc vào phương tiện cơ giới cá nhân. Việc quy hoạch bãi đỗ xe và thiết kế các dịch vụ đỗ xe cần xét đến yếu tố hành vi của người dùng để có thể cân bằng nguồn cung bãi đỗ với nhu cầu. Bài báo trình bày nghiên cứu về hành vi lựa chọn điểm đỗ xe công cộng ở khu vực trung tâm đô thị mới thông qua nghiên cứu trường hợp ba thành phố Thủ Dầu Một, Thuận An và Dĩ An của tỉnh Bình Dương. Nghiên cứu sử dụng phương pháp lựa chọn giả định và xây dựng mô hình lựa chọn rời rạc để đánh giá tác động của các yếu tố liên quan đến bãi đỗ xe lên hành vi lựa chọn điểm đỗ xe. Kết quả phân tích cho thấy mức phí đỗ xe, khoảng cách đi bộ tới bãi đỗ xe, thời gian và loại phương tiện đỗ có ảnh hưởng mạnh đến hành vi lựa chọn bãi đỗ. Một số yếu tố thiết kế dịch vụ đỗ xe cũng có có tác động mạnh tới hành vi lựa chọn loại bãi đỗ. Do vậy, việc quy hoạch vị trí các bãi đỗ xe cần đảm bảo hài hoà giữa yếu tố khoảng cách và mức phí đỗ xe. Các bãi đỗ xe cần được thiết kế đảm bảo cung cấp cho người dùng sự an ninh và các tiện ích phù hợp với loại phương tiện và thời gian đỗ xe
Strain orthogonal decomposition implemented within the phase field method with interfacial damage to model fracture in multi-phase heterogeneous materials
Authors: Vu Ba Thanh , Nguyen Xuan Lam , Do Anh Tu
Published: August 2023

In recent times, the phase field method is a robust simulation tool that can predict crack formation and propagation in structures. In brittle and quasi-brittle materials, the strain tensor is decomposed into negative and positive parts corresponding to the compression and tension behaviors when the structure is loaded. In the previous studies related to the phase field method, the strain tensor decompositions do not satisfy the orthogonal condition of these two parts, even if the elastic stiffness tensor is isotropic. This problem leads to inaccuracies in the mechanical behavior of the materials. In this paper, the strain tensor orthogonal condition is applied to the bulk strain tensor parts representing the internal strain of the component phases. This orthogonal condition is implemented into the phase field method with interfacial damage to simulate crack propagation in a sample containing multi-phase heterogeneous materials. Furthermore, the shape and area fraction of these phases are recognized by a supplemental sub-function which was studied in our recent paper from image formats. Through several examples, the obtained results are compared with the relevant numerical ones to demonstrate the correctness and effectiveness of the proposed method.
Analytical truss model for concrete beams reinforced with FRP bars
Authors: Tran Cao Thanh Ngoc
Published: August 2023

A truss model supplementing the concrete contribution is introduced in this paper to predict the shear strength of concrete beams reinforced with various types of FRP bars. The contributions from truss and direct strut mechanisms are considered in the analytical model. The truss model which has struts at various angles considering concrete contribution is derived in this paper. The concept of equivalent transverse FRP reinforcement is applied to integrate the concrete contribution into the proposed truss model. The shear strengths of concrete and FRP transverse reinforcements in the proposed model are calculated based on El-sayed et al. and CSA S806, respectively. The validity and applicability of the proposed model are evaluated by comparison with available experimental database, which consists of concrete beams reinforced with glass, carbon, aramid and basalt FRP bars. The comparison has shown a good correlation between the experimental data and analytical results. The proposed model is also compared with ACI 440.1R and CSA S806’s shear strength models and the better correlation is found. The results from this research shows that the properly-treated truss analogy can be used to assess the shear strength of concrete beams reinforced with various types of FRP bars.
A knowledge-based decision support system for incident traffic congestion management
Authors: Trinh Dinh Toan
Published: August 2023

A Knowledge-based Decision Support System (KB-DSS) based on a multi-stage Fuzzy Logic Controller (MS-FLC) is developed for traffic congestion management on expressways. The MS-FLC receives real-time traffic and incident data to analyse and anticipate the traffic conditions, to recommend alternative control measures in the form of natural languages for the human operator to select control decisions, and to calculate control settings to manage traffic congestion. In a case study, the KB-DSS is evaluated on a simulated network in comparison to ALINEA\Q, a popular ramp control method, across various traffic and incident situations. The results showed that: (i) the KB-DSS provides a systematic procedure in deriving control actions and a good capability to deliver linguistic expressions; (ii) the KB-DSS outperforms ALINEA\Q with respect to global objectives across many scenarios, attains significant improvements of mainline travel conditions and substantial reductions of ramp queues. These advantages make the KB-DSS a robust tool for traffic control for incident congestion management on expressways.

Máy phát điện nhiệt (TEG) là một trong những giải pháp tiềm năng để tận dụng năng lượng nhiệt khí thải của động cơ đốt trong vì khả năng chuyển đổi trực tiếp nhiệt năng thành điện năng. Các nghiên cứu tận dụng nhiệt bằng máy phát nhiệt điện có nhiệt độ mặt nóng cao và có độ chênh lệch nhiệt độ mặt nóng của TEG rất lớn gây ảnh hưởng tới hiệu suất và giảm tuổi thọ của thiết bị. Để giải quyết vấn đề trên, máy phát điện nhiệt sẽ được sử dụng kết hợp với két thu hồi nhiệt khí thải. Bài báo này sẽ mô phỏng quá trình truyền nhiệt của thiết bị tận dụng năng lượng nhiệt khí thải sử dụng cho máy phát nhiệt điện để đưa ra nhiệt độ mặt nóng và mặt lạnh của TEG trên phần mềm Ansys fluent. Kết quả mô phỏng cho thấy, nhiệt lượng thu hồi được bởi ống TEG với 24 mô-đun nhiệt điện là 1420W và độ chênh lệch nhiệt độ mặt nóng và nhiệt độ mặt lạnh từ 50 °C đến 100 °C.

Với những lợi ích về kinh tế, kỹ thuật và môi trường, việc sử dụng vật liệu mặt đường asphalt cũ (Reclaimed Asphalt Pavement-RAP) đang ngày càng trở nên phổ biến trên thế giới trong những năm gần đây. Để khôi phục đặc tính lưu biến và các tính chất khác của bitum cũ thu hồi từ vật liệu RAP (bitum RAP), phụ gia tái sinh thường được sử dụng trong quá trình sản xuất hỗn hợp asphalt có hàm lượng RAP cao. Bài báo trình bày nghiên cứu ảnh hưởng của phụ gia tái sinh gốc dầu mỏ (HS1 rejuvenator) đến một số đặc tính lưu biến của bitum. Các loại bitum được đánh giá bao gồm bitum mới 60/70, bitum RAP và bitum hỗn hợp (bao gồm bitum mới, bitum RAP với tỷ lệ tái chế (Recycled Binder Ratio - RBR) là 0,3 và phụ gia tái sinh). Phụ gia tái sinh HS1 được sử dụng với các hàm lượng khác nhau 0%, 4%, 12% và 20% theo khối lượng bitum RAP. Các thí nghiệm trong phòng được sử dụng để mô phỏng sự hoá già của bitum bao gồm hoá già ngắn hạn (short-term aging), hoá già dài hạn (long-term aging) và điều kiện chưa hoá già (unaged). Đặc tính lưu biến của bitum được xác định thông qua thí nghiệm cắt động lưu biến (Dynamic Shear Rheometer-DSR) theo tiêu chuẩn AASHTO T315. Kết quả nghiên cứu chỉ ra rằng, khi tăng hàm lượng phụ gia tái sinh, giá trị mô đun cắt động G* giảm và góc trễ pha tăng ở các điều kiện hoá già khác nhau. Phụ gia tái sinh HS1 có hiệu quả trong việc giảm độ cứng của bitum hỗn hợp và vẫn có khả năng làm mềm bitum khi trải qua quá trình hoá già dài hạn. Bitum hỗn hợp sử dụng khoảng 12% phụ gia tái sinh HS1 có thể đạt được giá trị cấp PG ở nhiệt độ cao tương đương với bitum mới 60/70.
