Authors: Shaker Farzaneh , Vardini Mohammad Taghi , Es’haghi Moosa , Kalhor Ebrahim Ghorbani
Published: June 2022

Magnetic nanoparticles and ionic liquid (IL, 1-hexyl-3-methyl-imidazolium bromide) based on graphene oxide (GO) composite provide unique physical and chemical properties in electrochemical sensors performance. Magnetic nanoparticles can cover active sites that increase chemical reactions with easy separation. IL increases the scan rate of electron transfer between the modified electrode and solution because it includes conductive adhesion properties. Also, IL in the next steps of design carbon paste electrodes (CPE) increases the cohesion. The study aims are to study the effects of magnetic nanoparticles and IL on the electrochemical detection of dopamine (DA). DA has a vital role in the mammalian central nervous system and change its value from the standard range leads broad mental diseases. But magnetic graphene oxide (MGO) may not exist capable of enhancing electrochemical signs alone. In this regard, after the synthesis of MGO, IL was established on composite. Then gold nanoparticles (AuNPs) and molecularly imprinted polymer (MIP) were modified MGO nanocomposite. MIP polymerization was continued by methacrylic acid (MAA) in the presence of DA as a template molecule. The developed sensor with modified nanocomposite studied by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The modified sensor based on nanocomposite with a broad concentration linear range, between 1×10-7 to 1×10-4 M and a limit of detection of 1×10-8 M (S/N=3) was used for the detection of DA in biological samples. Furthermore, these results prove that MGO was improved active sites of surface nanocomposite and IL was increased conductivity in the based electrochemical sensor for DA detection.

Rhabdomyolysis is a life-threatening skeletal muscle disease, the time of diagnosis and initiation of treatment which directly affects the likelihood of developing acute kidney injury and the quality of recovery of muscle function. The ultrasound method of diagnostics is accessible and can be used at the stage of primary diagnosis, but it has low a sensitivity of 68% and specificity of 57% when using such ultrasound symptoms as a diffuse expressed increase of echogenicity (homogeneous or heterogeneous), a disorder of transverse striation of the muscle structure and high volume of the muscular tissue damage (over 30%).
The possibility of ultrasonic elastography in the diagnosis of rhabdomyolysis in 95 patients admitted with suspected damage to muscle tissue is discussed. Comparison of the parameters of shear wave elastography in patients with rhabdomyolysis and patients with other diseases manifested by muscle edema (muscle contusion, inflammatory myopathies, post-exercise muscle edema), as well as with the control group, significant differences were noted (p 0.01) allows to determine the quantitative ultrasound characteristics of muscle tissue, pathognomonic for rhabdomyolysis. The use of shear wave elastography with obtaining lateral wave velocity of less than 1.64 m/s increased the sensitivity and specificity of the method in the diagnosis of rhabdomyolysis to 75 and 62%, respectively.
A logit model with integrated use of elastography indices was developed, with a diagnostic accuracy of 77%. During muscle recovery, there was an increase in lateral wave velocity to the level of control group values, which can be used as one of the markers of patient recovery.

Authors: Batov Vyacheslav E. , Kuznetsov Sergey M.
Published: June 2022

BACKGROUND: The use of personal protective equipment in contact with patients with new coronavirus infection is the basic measure to ensure the safety of medical personnel. It is known that the use of protective equipment made of materials with low hygroscopicity, air and vapor permeability, under high ambient temperatures and physical activity, can cause overheating of the body. Objectively, during the pandemic, medical personnel reported a deterioration in the functional state up to and even fainting, caused by prolonged use of protective suits. Protective equipment made it difficult to perform routine tasks and led to a reduction in the quality of work performed.
PURPOSE OF THE STUDY: Assessment of the effect of personal protective equipment on the functional status of medical personnel.
MATERIALS AND METHODS: A survey of 156 medical workers of military medical organizations was carried out using the original questionnaire. The ease of use of protective equipment was assessed, and at the same time the negative aspects of its use were identified. A study of the thermal condition of 6 volunteers during the use of reusable and disposable personal protective equipment sets was carried out under laboratory conditions.
RESULTS AND DISCUSSION: The majority of respondents reported a negative impact on the functional state of the body when using personal protective equipment. According to questionnaire data, skin damage occurred in 88% of cases; fogging of safety glasses in 81%; visual impairment in 70%; inadequate suit size in 61%; subjective feeling of heat at work in 61%; headaches in 45% of cases. An assessment of the thermal condition of the reusable and disposable suits at a temperature of 25C and light physical work indicated that the body heat levels of the volunteers were within acceptable normative values.
CONCLUSIONS: The use of personal protective equipment has a negative effect on the functional state of the medical workers body, which requires a rational approach to the selection of protective the provision of an optimal regime of work and rest Considering the possibility of using personal protective equipment under different conditions, including increased ambient temperatures (over +30С) and/or intense physical exertion, there is a need for further study of their effects in order to develop preventive measures.

Published: June 2022

One of the modern approaches aimed at improving the results of treatment of acetabulum fractures (AF) is the development of new fixators for columns and fragments of explosives. The frequency of AF fractures is from 2 to 22% of all pelvic injuries. The main cause of this injury is road accidents. In the treatment of AF fractures, open reposition and internal fixation with the use of various types of fixators, including plates made using additive technologies, are widely used. A fairly wide range of used and developed retainer designs is noted, from standard pelvic reconstructive plates, cables, wires, to modern plate designs. There is a clear trend of specialists in the widespread use of additive technologies that provide the manufacture of individual implants for the treatment of complex fractures of the AF. Analysis of the sources used has shown that reconstructive pelvic plates and cannulated screws are currently the unsurpassed leader in fixing columns and fragments of AF. More and more additive technologies are being introduced into the development and manufacture of individual plates and other fixing structures.

Many people, including rapper Snoop Dogg, actor William Shatner, Paris Hilton, Lindsay Lohan, Grimes, and Emily Ratajkowski, are enthusiastic about how Non-fungible tokens (NFTs) will bring value to create many beautiful arts for easy collection and trade in the dynamics of the art market. According to the OpenSea market estimates, the NFT projects available in the different blockchain is worth roughly 840 million US$. NFTs recently received enormous attention from both cryptocurrency investors and the media; even billionaire Elon Mask posted a Meme on his Twitter account and bought the sale of meme NFT for $19800. The biggest economic power that banned cryptocurrency last year, China, made a formal supportive statement to back NFT booming in the whole country. Suddenly, the red power realized the transaction order of the meta-verse system; the tokenized economy is an undoubted benefit for the living style of the current generation. Although the concept of NFTs is very new, trading activities are moving extremely fast in China. An exhibition like “Virtual Niche” can take up to three years to organize in the rest of the world, but it took just a few months in the second biggest superpower China, Beijing. Eventually, this new form of entity will make it easier and more capacitive for the Chinese style of politics, economy, and culture to stand strong in the world for thousands of years. This thesis will introduce the current NFT market development, trading models, and impact in China. With no hesitation, this time, China has entered the era of "everything can be NFT".

Published: June 2022

In 2020, the Coordinating Minister for Political, Legal, and Security Affairs of Indonesia, Mahfud MD, affirmed that any Indonesian citizen affiliated with ISIS would not be repatriated. However, Article 28D of the 1945 Constitution ensures that a person’s citizenship status is guaranteed as one of the human rights, as guaranteed in Article 15 of the Universal Declaration of Human Rights. For this reason, this research used a normative legal research method using statute and case approaches through literature review. The research raises the question of how is the protection of the rights to nationality for ex-ISIS based on international law? The research aims to discuss and analyze the rights to the nationality of ex-ISIS combatants under the implementation of international law, such as Article 1 (1) of the 1954 Convention Relating to the Status of Stateless Persons. The research results explain that the state’s discretion regarding nationality is particularly limited to conditions such as the prohibition of arbitrary deprivation, the duty to avoid statelessness, and the principle of discrimination, and everyone has a right to a nationality.

Authors: Ali Aljarallah Nasser , Kumar Dutta Ashit
Published: June 2022

Saudi Arabia's higher educational standards are gradually evolving to match the country's vision 2030. The importance of education and a strong emphasis on educational quality are the determinants to realize this vision. Recent studies reveal that the faculty members spend a lot of time preparing documents for the accreditation program and eventually may lose interest in the process. There is a lack of an automated system to prepare documents for accreditation and the need for one is strongly felt. Educational institutions entail multiple accreditations to ensure their quality. In addition, accreditation enables educational institutions to attract student communities. The study intends to develop an integrated framework to prepare documents and maintain quality practices for multiple academic accreditations. The proposed system employs application-programming interfaces for publishing data from the database that facilitates an added security to the primary data. Moreover, it automates the overall accreditation process and minimizes manual interaction. Researchers employed the database of the AlMaarefa University and used it as a testbed for implementing the framework.The initial set of results are promising and support educational institutions to improve their quality of service.

Published: June 2022

Thalassemia is an inherited disorder resulting from a mutation or deletion of a gene that causes one of the globin chains to experience a decrease or cessation in the rate of synthesis. This leads to a decrease in the rate of haemoglobin synthesis. The highest prevalence of thalassemia in the world is found in tropical countries. The incidence of thalassemia carriers in Indonesia ranges from 6-10%. Thalassemia screening can be carried out by several examinations, including one tube osmotic fragility (OTOF) examination, red blood cell index, peripheral blood morphology and electrochemistry of haemoglobin. This study aimed to examine the screening of thalassemia carriers in undergraduate students using osmotic fragment examination of the OTOF method. This study used descriptive methods with 100 TLM D3 female students not yet known to have thalassemia. Univariate analyses were carried out. The results of the capillary blood samples indicated that 12% of the students were positive (indicating a suspected carrier of thalassemia) and 88% were negative according to the OTOF method using a hypotonic solution of 0.36% NaCl. From the positive OTOF results, the percentage of haemolysis was measured with varying results (17% - 65%). Those who had positive OTOF results in general were without significant symptoms. The findings accentuate that early detection of thalassemia is important.

Menopause is a period of permanent cessation of menstruation which can cause the production of the hormones estrogen, progesterone and testosterone to stop. Quality of life is influenced by several factors including age, education, work and husband’s support. The purpose of this study was to determine the relationship between husband’s support and the quality of life of postmenopausal women in RW 11, the target area of the Babakan Sari Public Health Center in Kiaracondong District. A cross sectional study design was used. The sample consisted of 42 women aged 45-59 years with the criteria of normal menopausal women with husbands, recruited using accidental sampling. The WHOQOL-BREF (WHO Quality of Life - BREF) instrument was used to collect data on the quality of life, and husband’s support was measured using the Azwar questionnaire. Analyses included univariate analysis using frequency distributions and bivariate analysis using Spearman’s rank. 76.2% of respondents received high support from their husbands and 29 respondents (69.0%) had a good quality of life. A significant relationship was found (p = 0.01, with a correlation coefficient of 0.409, indicating a moderate relationship). This study therefore showed that there was a relationship between husband’s support and the quality of life of menopausal women in Kiaracondong District. So, it is very important for postmenopausal women to have the support of their husbands to improve and maintain their quality of life.

Published: June 2022

Type 2 diabetes mellitus (T2DM) is a public health problem in developing countries and has become the six highest cause of death in Indonesia. This study aimed to determine the relationship of physical activity and central obesity with T2DM. This was a case-control study, with a sample of 25 patients with T2DM in the Internist Polyclinic Dustira Hospital in Cimahi. The independent variables examined were gender, physical activity and central obesity, while the dependent variable was T2DM. Data were analyzed using the Chi-square test and odds ratios of the magnitude of the risk factor were calculated. Gender did not have a significant influence on the occurrence of T2DM (p-value = 0.40; OR = 0.5; 95% CI = 0.15-1.71). Physical activity did have a statistically significant relationship with the occurrence of T2DM (p-value = 0.0001; OR = 16.6; 95% CI = 4.04–68.04). Central obesity was also a risk factor for the occurrence of T2DM (p-value = 0.001; OR = 10.3; 95% CI = 2.77–38.21). We can conclude that the occurrence of T2DM is influenced by lifestyle factors such as low physical activity and central obesity.

Mâlikî Mezhebinde Namazda Setr-i Avret (Tesettür/Örtünme) Şartı İle İlgili Yaklaşımlar
Authors: YILMAZ İbrahim
Published: June 2022

İslâm’da setr-i avret (tesettür/örtünme) kadın ve erkek için farz olan hükümlerden biridir. Dinî/fıkhî bir terim olarak setr-i avret, vücudun şer’an/dinen örtülmesi gereken yerlerini (avret) örtmek, demektir. İslam hukukçuları, setr-i avretin namazın sıhhat/geçerlilik şartı olup olmaması hususunda ihtilaf etmişlerdir. Bu konuda biri (Hanefî, Şâfiî ve Hanbelî mezheplerin içinde bulunduğu) cumhura, diğeri ise Mâlikîlere ait olmak üzere iki temel yaklaşım bulunmaktadır. Cumhura göre setr-i avret namazın sıhhat şartıdır. Dolayısıyla setr-i avret şartına riayet edilmeden kılınan namaz sahih değildir. Bu şekilde kılınan namazın vakit içinde veya vakit dışında mutlak olarak iadesi gerekir. Setr-i avretin namazın sıhhat şartı olup olmaması ile ilgili Mâlikî mezhebinde ise iki yaklaşım bulunmaktadır. Birinci yaklaşım (kısmen) cumhur ile aynıdır. İkinci yaklaşıma göre ise (namaz ve namaz dışı diye bir ayırım olmaksızın) setr-i avret İslâm’da genel bir farz olup ayrıca namazın sıhhat şartı değildir. Bu ikinci görüşü kabul eden Mâlikîlere göre namazda setr-i avret şartına riayet sünnettir. Diğer taraftan Mâlikî mezhebinde namazın sıhhatine etkisi açısından avret, avret-i muğalleza ve avret-i muhaffefe diye ikiye ayrılmaktadır. Setr-i avretin namazın sıhhat şartı olup olmaması ile ilgili ihtilaf avret-i muğalleza ile ilgilidir. Avret-i muhaffefenin namazın sıhhat şartı olmadığı hususunda ise ittifak vardır. Setr-i avretin namazın sıhhat şartı olup olmaması ile ilgili klasik fıkıh doktrinindeki ihtilafın bazı fıkhî semeresi/sonuçları bulunmaktadır. Nitekim cumhura göre ister avret-i muğalleza olsun ister avret-i muhaffefe olsun avreti açık olarak kılınan namaz sahih değildir ve mutlak iadesi gerekir. Maliki mezhebinde ise avreti muğalleza ve muhaffefe olmasına göre farklı görüşler bulunmaktadır. Vücutta açılan yerin avret-i muğalleza olması halinde; Setr-i avreti namazın sıhhat şartı kabul edenlere göre namaz sahih değildir ve mutlak iadesi gerekir. Setr-i avreti namazın sıhhat şartı kabul etmeyenlere göre ise namaz sahih olmakla birlikte vakit içerisinde iadesi müstehaptır. Vakit çıktıktan sonra ise namazın iadesi gerekmez. Vücutta açılan yerin avret-i muhaffefe olması halinde ise tüm Mâlikîlere göre ittifakla namaz sahihtir. Vakit içerisinde iadesi müstehap olmakla birlikte vakit çıktıktan sonra iadesi gerekmez. Setr-i avretin namazın sıhhat şartı olup olmaması ile ilgili klasik fıkıh doktrinindeki ihtilafın özellikle avret-i muhaffefe açısından uygulamadaki örnekleri ile ilgili şu söylenebilir: Setr-i avreti namazın sıhhat şartı kabul etmeyen Mâlikîlere göre kadınların başı, dizden aşağısı ve kolları açık namaz kılması sahihtir. Yine onlara göre avret-i muhaffefeden sayıldığı için erkeklerin uylukları/kalçaları (fahz) açık namaz kılması sahihtir.

In Brazil, it is observed that the researchers in the field of Administration keep a certain distance to studies of National Defense. In this direction, the scope of this study is that there is an incapability between the strategic actions provided for in the National Defense Strategy (NDS) and the capabilities of the Defense Industry Base (DIB). It is assumed that companies linked to the DIB must know their dynamic capabilities, so that they can, in their strategic planning, develop actions that allow them to cooperate with the NDS, in addition to generating competitive advantage. The methodology used has a bibliometric nature. The findings point to i) the lack of studies that aim to propose strategies for the Defense sector, from the perspective of the theory of dynamic capabilities and business strategy; ii) the inexistence of Stricto Sensu Post-Graduate Programs in Administration, which have in their lines of research the National Defense theme; and, iii) the inexistence of journals in the area of Administration that have as scope or focus organizational studies, strategy and innovation in the area of National Defense. The Administration area has lines of research that cover strategic and organizational studies, innovation and technology, governance, public finance and others, which can collaborate with the advancement of studies on Defense in an applied way, as they aim to relate theory to practice and the constant search for pragmatic solutions to symptomatic and ongoing problems, through analytical, in-depth scientific methods and empirical observation.
Neuroimaging Correlates of Cognitive Behavioral Therapy for Insomnia (CBT-I): A Systematic Literature Review
Authors: Sabot Debbie , Baumann Oliver
Published: June 2022

Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard non-pharmacological treatment for insomnia, a complex disorder that comprises psychological, behavioral, and physiological components. This systematic literature review aimed to evaluate a growing body of exploratory studies that have examined CBT-I treatment effects using neuroimaging assessment. Nine studies met current review selection criteria, of which six studies compared insomnia groups with good sleepers, waitlist, and/or control groups. CBT-I administration varied in treatment length and duration across the studies, as did neuroimaging assessment, which included task-based and resting-state functional magnetic resonance imaging (fMRI), and structural magnetic resonance imaging (MRI). Functional connectivity abnormalities were observed in participants, including reduced engagement in task-related brain regions and apparent difficulties in regulating default mode brain areas that appeared to reverse following CBT-I treatment. Taken together, the neuroimaging results complement behavioral measures of treatment efficacy, indicating support for the effectiveness of CBT-I treatment in the recovery of brain function and structure.
The Contribution of Psychological Inflexibility and Metacognitive Processes to Emotional Distress
Authors: Quan Huan , Zettle Robert D.
Published: June 2022

Process-based cognitive behavior therapy (PB-CBT) may be informed by identifying shared mechanisms of disorder linked to shared processes of therapeutic change. Repetitive negative thinking (RNT) is a molar pathogenic process common to both generalized anxiety disorder and depression. Acceptance and commitment therapy (ACT) and metacognitive therapy (MCT) offer separate models of the relationship between RNT and emotional distress. In a pair of related studies, the relative degree to which processes specific to the two models accounted for variability in levels of generalized anxiety and depression in college student samples was evaluated. Across both studies, processes of cognitive fusion and obstructed valued living within the ACT model and beliefs about the negative consequences of RNT within the MCT model were most predictive of variability in levels of emotional distress. Limitations of this project as well as implications for further research and practice of PB-CBT for disorders of emotional distress are discussed.

Background and Purpose:Factors influencing work-life balance of regional hospital nurses are different from other professions. This study aimed to develop an instrument to measure work-life balance, and examine its psychometric properties.Methods:Psychometric properties were tested with content validity, construct validity using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and reliability with 598 professional nurses recruited using multi-stage sampling.Results:The Nurses’ Work-life Balance Scale (NWLBS) had 38 items and seven components, explaining 64.46% of total variance. Content Validity Index was 0.94. CFA results indicated good fit with empirical data. Cronbach’s alpha ranged from 0.53 to 0.94 for the seven subscales in 30 professional nurses.Conclusions:NWLBS demonstrated good content validity, construct validity, and reliability for assessing nurses’ work-life balance.

La tierra es uno de los materiales más abundantes y accesibles usados por la población rural del mundo para la construcción de viviendas, las cuales son principalmente adobes y muros tapiales. El Perú no es la excepción, ya que tiene bajo costo y fácil preparación. Sin embargo, este material muestra una resistencia a la compresión y flexión muy baja y casi nula resistencia a la tracción, también se deteriora rápidamente debido a agentes externos como la humedad, erosión, corrosión, entre otros. En el mundo se han venido desarrollando investigaciones con el fin de mejorar las propiedades mecánicas y físicas del adobe. En el Perú contamos con una norma dedicada al diseño y construcción con tierra reforzada (RNE). En esta norma podemos encontrar las condiciones mínimas que debe tener el adobe para tener un comportamiento óptimo como material de construcción. Sin embargo, el adobe fabricado en la sierra sur del Perú no llega a la mínima resistencia por lo cual se plantea la adición de fibras naturales con el fin de mejorar sus propiedades. La presente investigación tiene como finalidad encontrar el porcentaje óptimo de adición de fibra de Cabuya en la elaboración de adobe para mejorar sus propiedades mecánicas en la ciudad de Abancay, Departamento de Apurímac. Se añadió fibra de cabuya en las unidades de adobe con paja con diferentes porcentajes. El porcentaje de adición de fibra de 1.75% nos dio como resultado un aumento en 40% y 12% en la resistencia a la compresión y flexión respectivamente.

Aim: The aim of the study was to compare the two different hydrogel daily disposable contact lenses (HyDDCLs) satisfaction levels in patients with meibomian gland disfunction (MGD) and allergic conjunctivitis accompanied with short noninvasive tear break-up time (NIBUT).
Material and Methods: Fifty patients who had no history of contact lens and had short NIBUT were included to the study into two groups: allergic conjunctivitis findings (group 1) and MGD findings (group 2). All patients used both etafilcon A and nesofilcon A, respectively. The OSDI (Ocular Surface Disease Index) and CLDEQ-8 (Contact Lens Dry Eye Questionnaire- 8) tests were performed by the patients for each lens and the mean scores were compared. In addition, the decisions of all patients regarding the continued use of each lens were questioned.
Results: The mean of total scores of OSDI and CLDEQ-8 were statistically lower in nesofilcon A, significantly. The mean scores of the all OSDI subscales and the CLDEQ-8 subscales of dryness, discomfort, blurred vision and closing eyes were lower in nesofilcon A. Four patients (8%) were not satisfied by any of the lenses. 36 (72%) patients preferred nesofilcon A and remaining 10 (20%) patients preferred etafilcon A to continue.
Conclusion: Due to the hydrophilic structure and low modulus of the HyDDCLs, the satisfaction rate was found to be higher in the study group (92%). HyDDCLs could be a suitable option in cases where ocular surface diseases are accompanied. Hydrogel material with higher water content offers better comfort levels at the end of the day.

Multiple myeloma (MM) is an atypical plasma cell dyscrasia in the bone marrow (BM) which accounts for about 10% of all hematological malignancies. While extramedullary disease (EMD) is reported at a ratio of 6-20% in MM, cardiac and pericardial involvement is rare. In the event of cardiac or pericardiac involvement, on the other hand, progression into cardiac tamponade takes place in 60% of the patients. We will present a very rare case of recurrence with pericardial involvement after autologous stem cell transplantation
