Authors: Thomas Delphia , Pushpanjali  , Dayanandam Mala , Kondoj Navyasree , Anakarla Vishal , Dhanabalan Swathi
Published: September 2022

Introduction:

Assessment of age in adults is a difficult task in forensic medicine. In craniofacial structures, the mental, mandibular foramina and teeth are useful in age estimation. Because the pulp-to-tooth area ratio (PTR) based on secondary dentin deposition and the distance between the inferior border of the mental foramen and lower border of the mandible stays largely consistent over the course of a person's life, PTR and position of mental foramen are sensitive age markers.

Aim:

This study aims to assess an accurate method for age estimation, by comparing the results of the two different age estimation techniques such as mandibular canine's PTR and vertical position of the mental foramen using cone beam computed tomographic (CBCT) images.

Materials and Methods:

In 80 mandibular CBCT images, the pulp area and tooth area of the canine were measured from the axial section and a ratio was obtained. The same process was used for the sagittal sectional image. Another method involved measuring the mental foramen's four variables (X1, X2, X3, and X4) using a panoramic sectional image. The procured data were subjected to statistical analysis.

Results:

A negative linear relationship was acquired among the pulp cavity width, the height of the mandible (X1), and the age. Cubic regression analysis was performed, and the regression formulae were acquired. A mean difference of 2.11 years in axial section, 3.93 years in sagittal section, and 11.23 years in the mental foramen vertical position was acquired among the age estimated and chronological age.

Conclusion:

The sagittal sectional image of the mandibular canine's PTR is more accurate for determining age when compared with the vertical position of the mental foramen.

Authors: Ramani Roja K , Reddy Vinay Kumar
Published: September 2022

Introduction:

Panoramic radiographs are routinely used in dental clinics and are of great value in the diagnosis of calcified carotid artery atheromas. So the present study is aimed to know the prevalence of calcified carotid artery atheromas on the digital panoramic radiographs of patients with Type 2 diabetes mellitus and non-diabetic.

Aim and Objectives:

To determine the prevalence of calcified carotid artery atheromas in Type 2 diabetes mellitus and to assess the reliability of digital panoramic radiographs in detection of calcified carotid artery atheromas.

Materials and Methods:

A total of 100 subjects were included in the present study, 50 Type 2 diabetic patients and 50 age and sex matched healthy individuals were chosen as controls. Blood samples were collected and a digital panoramic radiograph was advised. To confirm those carotid artery calcifications (CACs) which were evident on panoramic radiograph further ultrasound Color Doppler was advised.

Results:

Among 50 Type 2 diabetic patients 9 (18%) patients showed CACs on digital panoramic radiograph and among 50 controls there were no CACs on digital panoramic radiograph with a statistically significant P value of 0.0022 (P < 0.05). Type 2 diabetes who exhibited CACs on digital panoramic radiograph also showed CACs on ultra sound Color Doppler.

Conclusion:

Our study concludes that people with Type 2 diabetes mellitus have more prevalence of calcified carotid artery atheromas on digital panoramic radiographs than non-diabetics.

Published: September 2022

Introduction:

Computed Tomography (CT) was the most used 3D radiographic diagnostic technique for years, but cone-beam computed tomography (CBCT) was created to reduce radiation exposure, costs, and accessibility issues

. Aim:

To evaluate the accuracy of CBCT measurements made at probable implant sites.

Materials and Methodology:

This was a retrospective study that compared panoramic reconstructed CBCT with RVG measurements at 77 probable implant sites, especially mandibular posterior tooth-bounded edentulous areas. Measurements made were the mesiodistal width of the edentulous area at the crest and at the highest point of the adjacent tooth's contour and the length of the natural teeth in the mandibular first molar region from the highest cusp to the apex next to the edentulous area. Statistical analysis was done with the Statistical Package for the Social Sciences (SPSS) and the independent t-test.

Results:

The mean difference between CBCT and radiovisiography (RVG) readings for mesiodistal width at the crest and highest contour of the edentulous bounded two neighboring teeth was −0.21039 and 0.02961, respectively, which was not statistically significant. The mean difference between CBCT and RVG readings along the tooth was 0.80481, which was statistically significant (P = 0.018). RVG outperformed CBCT (SD = 1.7) in estimating tooth length.

Conclusion:

Conventional RVG radiographic measurements were similar to real tooth length, whereas CBCT panoramic reconstructions underestimated the lengths by 15% but were clinically acceptable. Clinical CBCT application requires operator abilities and knowledge with software. It is critical to pay close attention to the calibration of data obtained from clinical examination and CBCT.

Authors: Naik Karunakar , Sujatha D , Raj Kiran H , Pai Anuradha , Naik Pooja , Shruthi M
Published: September 2022

Background:

To date, no simple and reliable method can replace oral biopsy site detection using Toluidine blue for early identification and treatment of potentially malignant oral disorders (OPMDs).

Aims and Objectives:

The study was conducted to assess the feasibility of using the colposcope and compare the findings with the toluidine blue staining method for selecting the biopsy site.

Materials and Methodology:

Study group included 30 patients; five patients dropped out as regression was seen in the lesion. Twenty patients with homogenous leucoplakia and five patients with nonhomogenous Leukoplakia formed a study group. An area with the most extensive cell change in the colposcopic examination was selected by the first version, Image J 1. x Software. After toluidine, blue staining was done. Dark blue-stained sites were considered positive, and site selection for the biopsy was made.

Results:

Normal vascular pattern in six (24%) cases, 10 (40%) cases showing punctuate vascular pattern, four (16%) of cases showed the mosaic vascular pattern, five (20%) of cases were with the atypical vascular pattern were assessed in colposcopic examination with statistically significant P value (0.009). Fourteen cases out of 20 cases of homogenous and all five cases of nonhomogenous leukoplakia were correctly diagnosed for the biopsy site with both toluidine blue and colposcopic techniques.

Conclusion:

In this study, Toluidine blue and colposcopic technique showed 76% accuracy for detecting the biopsy site. So colposcope can be an alternative diagnostic aid to toluidine blue in detecting biopsy sites for PMD.

Authors: Jaiswal Rahul , Kumar Atul , Chauhan Sandhya
Published: September 2022

Background:

Myocarditis, disseminated intravascular coagulation, and renal failure have been reported to be the leading causes of mortality in patients of severe diphtheria. The aim of this article was to study the clinico-demographic profile of diphtheria patients and also to evaluate the performance of Pediatric Risk of Mortality (PRISM) III on the prediction of mortality in such patients. The objective was to study the clinical profile of severe diphtheria cases in children.

Subjects and Methods:

During the study period, 170 patients were admitted to the pediatric emergency unit, out of whom 26 patients were admitted with the diagnosis of clinical diphtheria.

Results:

Majority of the patients were categorized as having either central nervous system or respiratory illness at the time of admission. The third largest category was patients with suspected clinical diphtheria. Forty-five out of 170 were nonsurvivors among which the highest mortality was noted in patients of diphtheria. All the nonsurvivors with clinical diphtheria had signs and symptoms of myocarditis either at the time of admission or developed later during the hospital stay. On comparing the mean PRISM scores of survivors versus nonsurvivors, it was not found to be statistically significant.

Conclusions:

The presence of myocarditis in patients of diphtheria is highly fatal and PRISM III alone is not sufficient for mortality prediction in patients of severe diphtheria.

Published: September 2022

Thyroglossal duct cyst (TDC) is the most common congenital anomaly of the neck. The thyroglossal duct is an embryological structure which connects the base of the tongue to the thyroid gland, which when fails to obliterate results in this anomaly. The incidence of this anomaly is approximately 7%, representing about 75% of the congenital masses of the neck. This cystic lesion is usually mobile and nontender in nature and usually presents with respiratory distress in infants. A lingual TDC is the rarest form of a TDC, and differs from a classical thyroglossal cyst totally in presentation and management. We present here a rare case of 2-month infant presenting with respiratory distress due to lingual TDC extending up to the suprathyroid region.

Autoresuscitation, also referred to as Lazarus phenomenon, is a rare occurrence whereby a patient may experience restoration of spontaneous circulation and signs of life after a diagnosis of “death” following unsuccessful cardiopulmonary resuscitation. “Found alive after declared dead” has often appeared as sensational news on print, electronic, and social media, and the medical fraternity falls prey to media trials and court enquiry, but this rare phenomenon remains underreported in the medical literature. In this article, we review the reports of Lazarus phenomenon in the medical literature and discuss possible explanations to throw some light on the medicolegal and social implications of this condition.

Authors: Kim Seon-Rye , Son Minkook , Kim Yu-Rin , Kang Hyun-Kyung
Published: September 2022

OBJECTIVES:We investigated the risk of dementia in older adults with chronic periodontitis according to the severity of periodontitis.METHODS: Data on patients with chronic periodontitis were extracted from the National Health Insurance Service-Senior cohort database from 2002 to 2014. Among 52,728 subjects eligible for inclusion, 11,953 subjects had newly diagnosed mild chronic periodontitis (MCP), and 40,775 subjects had newly diagnosed severe chronic periodontitis (SCP). Two 1:1 propensity score matched cohorts were created with 8,624 patients each in the MCP and SCP groups. To analyze the risk of dementia, a Cox proportional-hazard model was used to calculate hazard ratios with 95% confidence intervals (CIs).RESULTS: In the Kaplan-Meier curve, the disease-free probability was significantly lower in the SCP group than in the MCP group (p for log-rank=0.001). In the multivariable-adjusted model, the HR for the occurrence of dementia in the SCP group compared to the MCP group was 1.15 (95% CI, 1.04 to 1.27; p=0.009). A subgroup analysis revealed a significant association between dementia and the severity of periodontitis, especially in subjects who were male, aged ≥70 years, and had comorbidities.CONCLUSIONS: Reducing the severity of chronic periodontitis can help to reduce the risk of dementia. Therefore, it is necessary to aggressively conduct early dementia-prevention programs for males under the age of 70 that include dental health to prevent the progression of periodontitis from mild to severe.

Published: September 2022

The National Hospice and Palliative Care (NHPC) registry is a nationwide database in Korea that systematically collects information on terminally ill cancer patients receiving inpatient hospice care. From 2018 to 2020, a total of 47,911 patients were enrolled in the NHPC registry from hospitals providing inpatient hospice care. The NHPC database mainly contains the socio-demographic and clinical information of the registered patients. Among these patients, approximately 75% were 60 years or older, and the ratio of males to females was 1:1.41. Lung, liver, colorectal, pancreatic, and gastric cancer made up nearly 90% of the cancer sites among the registered patients. Upon their initial admission to the hospice ward, around 80% of the patients were aware of their terminal illness. About half of the patients had mild pain at the time of the initial admission to the hospice ward, and the duration of hospice care was 14 days (interquartile range, 6-30) in 2019 and 2020. The NHPC registry aims to provide national statistics on inpatient hospice care to assist health policy-making.

The objective of this study was to determine the etiology of febrile illnesses among patients from October 1, 1993 through September 30, 1999, in the urban community of Iquitos in the Amazon River Basin of Peru. Epidemiological and clinical data as well as blood samples were obtained from consenting patients at hospitals, health clinics and private residences. Samples were tested for arboviruses in cell cultures and for IgM and IgG antibodies by ELISA. Blood smears were examined for malaria, and sera were tested for antibodies to Leptospira spp. by ELISA and microscopic agglutination. Among 6,607 febrile patients studied, dengue viruses caused 14.6% of the cases, and Venezuelan equine encephalitis virus caused 2.5%, Oropouche virus 1.0%, Mayaro virus 0.4%, and other arboviruses caused 0.2% of the cases. Also, 22.9% of 4,844 patients tested were positive for malaria, and of 400 samples tested, 9% had evidence of acute leptospirosis. Although the study was not designed to assess the importance of these pathogens as a cause of human morbidity in the total population, these results indicate that arboviruses, leptospirosis, and malaria were the cause of approximately 50% of the febrile cases. Although the arboviruses that were diagnosed can produce asymptomatic infections, our findings increased the overall understanding of the relative health burden of these infections, as well as baseline knowledge needed for designing and implementing further studies to better assess the health impact and threat of these pathogens in the Amazon Basin of Peru.
Leadership Re-appropriated for 21st - century Women: A Reading of Deuteronomy 17:15–20
Authors: Pietersen Dr Doniwen
Published: September 2022

This article explores the Ancient Near East and Deuteronomy 17:15–20 from a feminist perspective in order to reappropriate the patriarchal recollections of failed male leadership and attempts to invertedly stifle female leadership. If one considers the aforementioned text by reflecting on its context, there is also an obligation to bear in mind gender sensitivities, feminism and complexity of the 21st century, but more importantly one needs to move beyond this toward the inclusiveness of women by the reappropriation of such texts (both from the Ancient Near East and Deuteronomy 17:15–20). Using a feminist lens, a combination of the sociological-historical and critical method will assist the reader in juxtaposing and navigating these two complex contexts. Literature relating to Hebrew culture predominately reinforces the status of male leadership to highlight their society’s need for strong leaders. However, seldom was female leadership considered a viable alternative or what, if any, the shortcomings of such leaders might be. However, if 21st -century women are to reappropriate Deuteronomy 17 in order to prioritise female leadership, various levels of society could stand to benefit. Women leadership, if given a chance, has the potential to edify people’s legal and political status.

AUTOCRATORISSA MARIA ALANSKAYA IN THE SYSTEM OF DYNASTIC RELATIONS OF ALANIA, THE BYZANTINE EMPIRE AND GEORGIA
Authors: МАЛАХОВ С.Н.
Published: September 2022

В статье на основе письменных и сфрагистических материалов исследуются главные страницы биографии византийской императрицы Марии Аланской, сыгравшей большую роль в укреплении алано-византийских и грузино-византийских межгосударственный связей во второй половине XI в. Автократорисса Мария, племянница аланского эксусиократора Дургулеля и дочь грузинского царя Баграта IV, в византийском обществе была известна как «аланисса». Рассматриваются причины закрепления за ней этого этнического имени, которое нельзя рассматривать как ошибочное. Мария Аланская сохраняла свою культурную идентичность по материнской линии: в частности, она способствовала расширению алано-византийских связей и укреплению позиций аланской знати в составе господствующего класса Византийской империи. Мария активно участвовала в легитимации династии Комнинов, культурной и церковной жизни византийского общества. Сближение Алании, Грузии и Византии с середины XI – начала XII в. было предопределено единым вероисповеданием и возросшей внешнеполитической угрозой со стороны турок-сельджуков. Матримониальные союзы между правящими династиями соседних держав становились основой для развития тесного военного и политического сотрудничества.Актуальность статьи определяется ростом исследовательского интереса к проблемам религиозной самоидентификации современных осетин на базе религиозной принадлежности их предков. Новизна исследования определена привлечением новых источников, в частности, данных сфрагистики. Целью статьи является выявление роли Марии Аланской в укреплении международных связей православных государств. Интерес представляет еще и тот аспект, что для средневековых обществ активное политическое участие женщин даже с высоким социальным статусом не было нормой. Тот факт, что до нас дошли свидетельства подобной активности женщины, указывает на ее безусловную неординарность.
Relative Strength Performance Evaluation of Self-Compacting and High Strength Concrete Beams containing Polyethylene Terephthalate
Authors: Wasiu John , Joseph Sule
Published: September 2022

This research compares the flexural resistance of self-compacting concrete (SCC) and High Strength Concrete (HSC) beams with embedded polyethylene terephthalate (PET) plastic bottle below the neutral axis using concrete grade of C70. Mix design for both SCC and HSC were performed in line with relevant specification. Experimental programme was achieved on both beam specimens. Workability, compressive and flexural strength tests were performed in the laboratory.  The workability test revealed a more flowable concrete with the SCC mix than that of the HSC. The compressive strength for the SCC design mix yields a higher value (about 21.5% higher) than that of the HSC. The flexural resistance of each beam specimens (SCC beams and HSC beams) increases with increase in curing days of the beams but higher strength was achieved with SCC beams at 28 days curing. The stress-strain behavior is within the specified acceptable limit (0.002-0.0035) for concrete with grade less than or equal to C50/C60. It is concluded that the replacement of concrete with PET plastic bottles beneath the neutral axis will lead to reduction in volume of materials, reduction in environmental waste, price of removal of the garbage and eco-friendly environs.
Strength Potentials of Rattan Reinforced Concrete Using Concrete Grade C30/35
Authors: Wasiu John , Joseph Sule
Published: September 2022

Steel reinforcements have been widely used in concrete work in order to help improve its tensile resistance against applied loads. But steel is susceptible to corrosion due to water ingress through cracks, increased in cost of purchase and dangers associated with maximizing profit due to greed. Rattan fiber is also known to be a suitable structural material both in compression and tension. Hence, this study examines the extent of application of rattan in concrete. Experimental investigation was carried out on conventional concrete (CC), rattan reinforced concrete cubes (RR, RS and SR), control beams (CTBM) and rattan reinforced concrete beams (RRBM, RSBM and SRBM). Compressive and Flexural strength tests were conducted on the samples at 7,14,21 and 28 days. The results revealed great potential of rattan when included in concrete work. The strength obtained is approximately twice that of conventional concrete. The modulus of Rupture (MoR) for all beam samples also revealed similar trend. The study concludes that rattan can partially replace main steel bars by approximately 50% in beams with suitable applications in light load bearing elements like lintel beams, roof beams, and spandrel.

The evaluation of selected public swimming pools within Sango-Ota metropolis was done to determine whether the pools adapt to the recommended WHO standard for swimming pool water. Six pools were selected based on the average population per use and user ratings. A total of 12 water samples were analysed physicochemical and microbial qualities using standard methods. The  physicochemical characterization results are as follows; pH, 5.00 - 5.73 with mean value of 5.3; Total Dissolved Solids (TDS), 44.00 - 48.50 mg/L with mean 46.0 mg/L; Alkalinity, 24.00 - 28.50 mg/L with mean 26.0 mg/L; total hardness, 0.80 - 1.23 mg/L with mean 1.0 mg/L; iron, 0.05 – 0.69 mg/L with mean 0.3 mg/L; residual chlorine, 1.06 – 3.25 mg/L with mean 1.9 mg/L. The microbial characterization results are as follows; Zero count for Salmonella-shigella; Total Aerobic Plate Count (TAPC),1360 - 7270 cfu/mL; Escherichia coli count, 0 - 7 cfu/mL; coliform count, 2 – 25 cfu/mL.  The isolated microorganisms from the pools were Escherichia coli, Proteus Vulgaris, Yersinia Enterocolitica, Proteus Mirabilis, Citrobacter Freundi and Vibro Chlorea occurred in 8.33%, respectively while Klebsiella Pneumonia, Entrobacter Aerogenes, Pseudonomas sp. occurred 16.67%. The pH of the analysed pools didn’t comply with the WHO standards while other physicochemical parameters conform to the standard except for pools C and F which had a higher concentration of iron. However, the existence of pathogenic microorganisms in the pools classified them as unsafe for swimming activities. This study recommends routine testing and comprehensive treatments with respect to regulatory standards.  Pool managers should strictly adhere to the bathing load limit and ensure the pool users take shower before using the swimming pools to forestall the outbreak of waterborne diseases
Small-Scale Energy Generation for Remote Rural Areas using Solar-Powered Compressed Air Storage System
Authors: Uzedhe Godwin O. , Akinloye Benjamin O.
Published: September 2022

Energy reach in the rural areas is still of major concern today especially in developing nations. Small-scale energy generation with stored compressed air is the focus of this work towards solving the energy deficit in remote rural environments through renewable sources. The method involves an experimental setup that harnessed energy from the sun through solar PV for isothermal compression and expansion of an air storage system to gain the advantages of low cost, longevity, and environmental friendliness of air storage in small scale electrical power generators. Results from a small, scalable, artificial air storage system of 360m3 show that one charge results in approximate temperature loss of 29oC for compression and 10oC for expansion (in a single cycle). A pressure charge of about 6bars from a compressor speed of 300rpm was also obtained and was able to maintain a constant alternator speed of 2500rpm on no load to produce electricity at 230Vac during expansion.  When advanced and standardized, the air storage could provide a medium for cheap electrical energy storage for small scale renewable sources and a means for electrical energy availability in remote rural environments.

Published: September 2022

Cooperative Communication (CC) has greatly reduced the effect of multipath fading, thereby improving the quality of transmitted signals in wireless ad-hoc networks. However, existing works on CC suffers from degradation of network lifetime due to inaccurate selection of the optimal relay terminal. This results in frequent battery recharging due to high energy consumed and battery depletion. Hence, in this paper, lifetime enhancement of cooperative wireless ad-hoc networks is carried out using allocated optimal power and relay selection scheme to ensure an optimal selection of the best relay by balancing and conserving the energy consumption of the nodes. Transmit power optimization problems were formulated for Amplify-and-Forward (AF) and Decode-and-Forward (DF) relaying strategies to obtain the optimal power allocations required to transmit the information. The proposed scheme named Energy-Aware Relay Selection (EARS) was simulated in MATLAB software environment and average network lifetime performance evaluation was performed. The result obtained shows that the proposed EARS improves the network performance by 10.06% and 3.56% for AF and DF relaying strategies, respectively over the existing power-aware relay selection schemes.

Published: September 2022

The unique characteristics of the green synthesis pathway have opened the way for a new field of scientific investigation. The current study used green chemistry methodologies to produce pure zinc oxide (ZnO) (G1) and silver doped zinc oxide (Ag doped ZnO) (G2) nanoparticles (NPs) using Gymnema sylvestre (G. sylvestre) leaf extract as a reducing as well as capping agent. XRD, FESEM, EDAX, and FT-IR investigations were used to investigate the structural characterization of G1 and G2 NPs. The UV–Vis and PL analyses were used to examine the optical characteristics. The results clearly reveal that the leaf extract is the best possible stabilizing agent for the manufacture of G1 and G2 NPs, and that the generated nanoparticles operate as potent microbial agents, inhibiting the growth of a variety of dangerous microbes. Due to their eco–friendly and non–toxic compatibility, the prepared G1 and G2 NPs can be employed for therapeutic and other purposes.
REBUS SIC STANTIBUS (Fundamental Changes in Conditions) PRINCIPLE ON THE ROAD TO THE MONTREAUX CONVENTION
Authors: BOLAT Mahmut , GÜNEŞ Burak
Published: September 2022

This study argues that the new order established by Turkey with the Montreux Convention is based on the principle of rebus sic stantibus, which is one of the essential principles of international treaty law. According to the relevant principle, it is emphasized that if the conditions at the time of conclusion of a treaty have undergone radical changes, the application of the treaty becomes impossible. This presents a traditional way of ending the provisions of treaties concluded within the system. Turkiye argued that the order established by the Lausanne Treaty on Straits underwent radical changes, and therefore the status of the Straits should be determined with a new agreement. From this point of view, in this study, it is argued that Turkiye complies with international law and diplomacy and acts in good faith to change the Straits regime. To support this argument and trace the principle of rebus sic stantibus, methodologically, the newspapers of the period were scanned. In addition to this, doctrinal research was used, and state archives benefitted. In this study, the document analysis method, one of the qualitative research methods, was utilized.
EMERY KELEN AND ALOIS DERSO ARE THE CARTOONISTS OF THE LAUSANNE CONFERENCE, AND THE CARTOONS OF TURKISH DELEGATES
Authors: ÖZGEN Yüksel
Published: September 2022

After the Ottoman Empire, defeated in the First World War, signed the Armistice of Mudros, the occupations began. The national liberation struggle of the Turkish nation against the occupations officially ended with the Lausanne Peace Treaty signed on July 24, 1923, at an international conference in Lausanne, Switzerland. The process experienced in the Lausanne Conference and the agreement signed afterward has been the subject of many works written by local and international authors. This article discusses another aspect of the Lausanne Conference, which has a special place in Turkish history. The only visual recordings during the conference process, where cameras were prohibited, were the drawings made by painters and cartoonists. Among the cartoonists attending the Lausanne Peace Conference are Emery Kelen and Alois Derso. The article examined the short biographies of these two cartoonists and some of their drawings about the Turkish delegation.
Immunologische aspecten van Covid-19-ziekte en van vaccinatie tegen SARS-CoV-2 Deel 2: Variaties van het immuunantwoord individueel en in de tijd bij een infectie met SARS-CoV-2 en bij vaccinatie

Published: September 2022

Individual variations in the immune response in Covid-19 infection or after vaccination and quantitative changes with time

Pronounced individual differences in immune responses following a SARS-CoV-2 infection or COVID-19 vaccination have been noticed. Importantly, an early and profound T cell response to the virus with the production of high amounts of interferon-gamma (IFN-γ) and interleukin-2 (IL-2) and low amounts of tumor necrosis factor-alpha (TNF-α) results in asymptomatic or mild disease, in contrast to what happens in patients getting seriously ill. In order to develop efficient vaccines and targeted immunization schedules, it is important to measure T cell responses and the antibody production induced by the various vaccines, since the immune response depends on not yet fully defined genetic properties, age, comorbidities, used medication, etc. The strongest recall is seen in convalescent persons after vaccination (‘hybrid immunity’). Because of waning of the immunity and the continuous emergence of virus variants, regular repeat vaccinations and the development of stronger second-generation vaccines, maybe with the recognition of a more extended antigen spectrum, appear necessary. Special attention should be given to high-risk patients.

Summary Introduction: High-frequency audiometry is not usually carried out during routine hearing examinations. It is a frequently used method at the ENT Clinic of the University Hospital Motol (especially in patients being treated for tumours of the pontocerebellar angle), although the exact indicative criteria for this have not been determined. We aimed to characterize a group of patients, using a method which improved the accuracy of the diagnostics. Material and methodology: We analysed 1,515 audiograms retrospectively. These audiograms were performed by using audiometer MADSEN Astera of GN Otometrics during 2011–2018 in 773 adults, aged 16–80 (47.79 ±13.54). They all underwent high-frequency audiometry comprising of all commonly examined frequencies up to 8 kHz, and also at higher frequencies of – 9 kHz, 10 kHz, 11.2 kHz, 12.5 kHz, 14 kHz a 16 kHz. The indication was very diverse – subjective hypacusis/hyperacusis, tinnitus, vestibulopathy, acutrauma, or an already known diagnosis of a pontocerebellar tumour. Results: We identifi ed a clinically signifi cant asymmetry or pathological elevation of the hearing threshold, which was only detectable at frequencies above 8 kHz in 52 patients (6.73%). This group consisted of patients with vestibular schwannoma (48.08%), other tumours and vascular malformations of the temporal region (11.53%), vestibulopathy (3.85%), and patients that had never developed a serious pathology (23.08%). They were mostly patients with straightforward hypacusis or tinnitus. Conclusion: In clinical practice, there are cases of patients with a hearing defect that can only be detected when HFA is performed. HFA clarifi es the diagnosis of hearing disorders and can lead to the detection of potentially life-threatening conditions such as tumours and vascular malformations of the otological area.

Determining Relationship Between Headache and Cyberchondria Levels in University Students with Headache
Authors: TORLAK Mustafa Savaş , TÜRKTEMİZ Halil
Published: September 2022

Background: University students may experience various health problems throughout their education life. One of the most common health problems faced by students is headache. Today, university students use the internet extensively to access information. Therefore, it is predicted that university students with headaches may tend to search for health information on the internet.

Purpose of the Study: In this study, it was aimed to determine the relationship between headache and cyberchondria levels of university students with headache.

Method: A questionnaire form was used to collect data in the descriptive study. The questionnaire form included Socio-demographic form, Cyberchondria Scale, Headache Impact Test (HIT-6) and Visual Analog Scale (VAS). The study data were obtained from the Vocational School of Health Services of a University in Konya. 225 volunteers whose headaches lasted more than 30 minutes were included in the study.

Findings: 88.4% of the participants were female students and 11.62% were male students. Headache impact levels (60.19±7.99) and pain severity (6.75±1.88) of the participants were high. Headache impact level and severity of female students were higher than males (p
EVALUATION OF TRANSACTIONS RELATED TO THE INVENTORIES IN TERMS OF LMSE FRS AND SME FRS
Authors: YAZARKAN Hakan
Published: September 2022

Companies subject to independent audit but do not apply Turkish Accounting Standards (TAS) have been applying Financial Reporting Standards for Large and Medium-Sized Enterprises (LMSE FRS) as of 01.01.2018. In addition, the Financial Reporting Standard for Small and Micro Enterprises (SME FRS) was drafted by the Public Oversight, Accounting, and Auditing Standards Authority in 2019. This draft, which has not been enacted yet, is likely to enter into force soon. This study aims to comparatively evaluate the provisions of LMSE FRS and SME FRS at the point of accounting for the inventory movements of the enterprises. In this direction, in the research, firstly, the regulations regarding the inventories in SME FRS and LMSE FRS are revealed. Then, how the transactions explained theoretically according to both standards will be accounted for in practice is explained with the help of examples. As a result of the research, it has been determined that the provisions of SME FRS and LMSE FRS in terms of transactions related to inventories overlap in some points and differ in some points.
As universidades comunitárias e os ODS: entre o compromisso com o bem público e a submissão ao mercado
Authors: Fioreze Cristina
Published: September 2022

Os esforços na direção de uma perspectiva sustentável de desenvolvimento são crescentes e ganham intensidade a partir do contexto da pandemia da Covid-19, tornando ainda mais pertinente a Agenda 2030 e seus Objetivos do Desenvolvimento Sustentável (ODS). O artigo discute o compromisso da educação superior com a realização dos ODS e, nesse sentido, analisa o modelo comunitário de universidade buscando compreender de que forma e em que medida ele ainda apresenta aderência aos ODS, tendo em vista o contexto de crise e acirramento da competição mercantil que vivencia. Metodologicamente, ancora-se em pesquisa qualitativa e de campo realizada junto a amostra de quatro universidades comunitárias, com dados coletados através de entrevistas semi-estruturadas com doze gestores e pesquisadores dessas instituições. À luz do enquadramento teórico proposto por McCowan (2019), os dados foram analisados em três eixos: tendências no engajamento com a comunidade: ensino, pesquisa e extensão; forças centrípetas: pressões em direção à homogeneização com modelos institucionais convencionais; e entre a responsividade democrática e a responsividade baseada no mercado. Como resultados, constata-se que as relações universidade-sociedade passam por transformações, mas o modelo ainda preserva o compromisso com o desenvolvimento regional. Ao tempo em que a natureza porosa das instituições comunitárias é elemento facilitador para o compromisso com os ODS, também facilita a aproximação com o mercado e pode prescrever uma submissão a ele, numa tendência de isomorfismo com a universidade empresarial. Isto descaracterizaria o modelo comunitário enquanto tal, levando-o a perder seu potencial de alternativa para a realização dos ODS.

Authors: Maldonado Daniel Teixeira , Garcia Neira Marcos
Published: September 2022

O objetivo desse estudo foi analisar como os(as) professores(as) de Educação Física sistematizaram experiências político-pedagógicas na educação básica em que a relação entre as desigualdades socioeconômicas e as práticas corporais foram problematizadas com o intuito de buscar a justiça social. Foram analisados 22 relatos de experiências educativas, publicados entre os anos 2009 e 2020, em três periódicos científicos indexados no qualis da Educação Física, além de oito livros que apresentaram capítulos sobre o tema. O material empírico foi submetido à análise cultural. Ao tematizar os jogos eletrônicos, spinner, jogos de tabuleiro, jogos tradicionais, jogos de carta, ioga, boliche, skate, futebol, tênis, rap, hip hop, taco, realização de megaeventos esportivos no Brasil e os espaços de lazer existentes nas comunidades, os(as) docentes tensionaram as desigualdades socioeconômicas que atravessam essas manifestações da cultura corporal, problematizando os saberes historicamente construídos pela humanidade a respeito dessas temáticas durante as aulas do componente curricular.
Lives Amid Violence
Authors: Schomerus Mareike
Published: September 2022

This book is available as open access through the Bloomsbury Open Access programme and is available on www.bloomsburycollections.com.

Violent conflict and its aftermath are pressing problems for international development. However, the results of development in conflict contexts have generally been disappointing and their preventative potential thus questionable. Lives After Violence argues that this is due to development practitioners adhering to an outdated and ineffective paradigm, which emphasises statebuilding, stabilisation and service delivery.

Through detailed analysis of ten years of case studies and quantitative survey results from conflict-affected countries (Afghanistan, Democratic Republic of Congo, Nepal, Pakistan, Sierra Leone, South Sudan, Sri Lanka, Uganda), this book offers original and generalisable conclusions about how lives in conflict work and upends the status quo of development practice in conflict settings by offering a set of new paradigms. These include the need to pay attention to the long-term effects of conflict on individual behaviour and decision-making, the social realities of economic life, the link between relationships and capacity and the role service delivery plays in negotiating the relationship between citizens and states in the aftermath of conflict. The book concludes with practical recommendations on how to apply and practice these new paradigms.
Curating Italian Fashion
Authors: Augello Matteo
Published: September 2022

Since the 2000s, fashion exhibitions have become some of the most popular displays presented in museums. Fashion brands celebrate anniversaries with blockbuster retrospectives and lavish catalogues, and increasingly exhibit archive pieces in their stores. Italy is a major player in the global fashion industry, yet little has been written about its contribution to fashion curation. This book explores the management, display and curation of Italian fashion heritage, highlighting the role played by companies and industry associations.

By contextualising fashion curation within Italy’s economy, culture and art-historical tradition, this book unfolds the ties between the preservation of fashion heritage and corporate policies. It traces the shift of companies from sponsors to cultural producers and discusses the different uses of archives and exhibitions. Through the critical analysis of key examples such as Salvatore Ferragamo, Pitti Immagine and Gucci, this book illustrates how the inevitable commercial interests underlying fashion curation can exist alongside the scholarly contribution of corporate initiatives. Most importantly, it defines the curatorial approaches developed by the involvement of the industry in fashion curation, thus providing an overarching interpretation of the characteristics of this practice in Italy.

Matteo Augello provides an unprecedented insight into the management of Italian fashion heritage and presents a comprehensive account of the development of fashion curation in Italy, drawing from archival records, existing literature and oral history. This book is essential reading for scholars, industry professionals and students interested in the intersections of curation, heritage, national identity and corporate cultural policies.
Rethinking Education for Sustainable Development
Authors: Iyengar Radhika , Caman Ozge Karadag
Published: September 2022

This book explores how education can be used as a tool to promote sustainability practices as the world faces huge challenges related to climate change and public health. The chapters consider all types of literacy approaches that fall under the umbrella of Education for Sustainable Development (ESD). These approaches include scientific literacy, ecological literacy, health literacy, education on climate change and climate resilience, environmental education and others linking education, global health, and the environment more broadly. “Education” is used in the widest sense to incorporate non-formal, informal and formal/school settings. This volume will help to bring these interconnected areas together and interrogate their research methods, assumptions, field-based application and their policy potential. Taking a critical approach to ESD, the book suggests new pedagogies, tools, and technologies to strengthen the way we educate about sustainability issues and go beyond the current thinking about ESD. The book includes a foreword by Jeffrey Sachs, Director of the Center for Sustainable Development at Columbia University, USA.
