BİÇİM-SÖZ DİZİMSEL İSTEM: TÜRKÇEDE DURUM BİÇİM BİRİMLERİ VE ANLAMSAL İSTEME ETKİLERİ
Authors: KARACAN Neslihan
Published: December 2022

Bir cümlede sözcükler çeşitli hiyerarşik durumlara göre bağımsallık ilişkisi içerisindedir ve bu hiyerarşik ilişkileri çözümlemeye çalışan dil bilgisi kuramı bağımsal dil bilgisi olarak anılır. Bağımsal dil bilgisi kuramında, bağımsallık ilişkisi içinde bulunan her tür sözcüğün yönetim kapasitesini ifade eden teori ise istem (valency) terimi ile karşılanmaktadır. İlk kez Tesnière tarafından fiil temelli olarak açıklanan bu teorinin, bugün artık öbek yapı içerisinde yönetici pozisyonunda yer alan edat, ad, sıfat gibi diğer sözcük türlerinin de istem değerlerinin olduğunun ortaya konulmasıyla, araştırma sahası genişlemiştir. Cümle ya da öbek yapı içerisinde bu bağımsallık ilişkilerinin işaretçileri dillere göre farklılıklar göstermektedir. Kimi dillerde sözcük düzeyinde işaretçiler bu görevi üstlenirken kimi dillerde de biçim birimler düzeyinde kendini gösterebilir. Türkçede bu işaretleyiciler dilin yapısı gereği biçim birimleri ile işaretlenmektedir. Söz dizimsel istemin bir yansıması olan bu yapılar biçim-söz dizimsel istem adı altında incelenmektedir. Türkçede biçim-söz dizimsel işaretleyicileri olan durum ekleri ve anlam isteme katkıları çalışmanın temeli olmuştur. Türkçede araştırmacılar farklı sayılarda durum işaretleyicileri öne sürmektedirler ancak temelde hemfikir olunan beş durum işaretleyicisi (yalın, belirtme, bulunma, yönelme, ayrılma) araştırmanın içeriğini oluşturmuştur. Bu durum işaretleyicilerin anlamsal isteme katkıları ve istem çerçeveleri içerisinde yüklendikleri anlamsal roller durum işaretçilerinin türüne göre incelenmiştir. Durum işaretçilerin anlamsal isteme etkileri fiillerin ve edatların tamlayıcıları olan adlar üzerinden değerlendirilmiştir.

Published: December 2022

Ekonomik büyüme sürecinde sanayi sektörü özel bir yere sahiptir. Ancak ülkelerin sanayileşme sürecinde önemli olan sanayi üretimi istenilen seviyeye ulaşmadan düşmekte ve ülkeler erken bir süreçte sanayileşme hedefinden vazgeçmektedir. Tarım ekonomilerinin zamanla sanayi ekonomilerine dönüşüm geçirmesi üç sektör kuramının ilk gelişim basamağını oluşturmaktadır. Bir ülkenin fiziki sermaye birikiminin oluşması sonucunda ekonomik büyümenin gerçekleşeceği savunulmaktadır. Kaldor’un ekonomik büyüme ve sanayi üretimi arasındaki pozitif yönlü ilişkisi ampirik olarak birçok araştırmacı tarafından araştırılmaktadır. Bu çalışmada sanayi sektörü katma değerinin fiziksel ve beşerî sermaye birikimindeki gelişmelerden nasıl ve ne yönde etkileneceği araştırılmıştır. Bunun için 34 OECD ülkesine ait 1996 2018 yılları arası yıllık veriler üzerinden elde edilen Driscoll Kraay Standart Hatalar Tahmincisi sonucunda, fiziksel sermayedeki iyileşmelerin sanayi sektörü katma değerini olumlu yönde etkilediği bulunmuştur. Buna karşın beşerî sermaye harcamalarındaki artışın ise sanayi sektörünün payını azalttığı sonucuna ulaşılmıştır.

Araştırmanın amacı, Spor Bilimleri Fakültesi öğrencilerinin Oyun Bağımlılığı (OB) düzeyinin cinsiyet, sınıf düzeyi, ekonomik durum algısı ve başarı durumuna göre anlamlı bir farklılık gösterip göstermediğini belirlemektir. Genel tarama modelinde tasarlanan bu çalışmada veriler 27’si kadın ve 114’ü erkek olmak üzere toplam 141 gönüllü katılımcıdan elde edilmiştir. Veri toplama aracı olarak Ilgaz tarafından Türk diline uyarlanan, yedi alt boyut ve 21 maddeden oluşan Ergenler İçin Oyun Bağımlılığı Ölçeği kullanılmıştır. Ölçeğin geri çekilme alt boyutu ile ilgili olarak hesaplanan iç tutarlılık katsayısı düşük olduğundan (.42) bu alt boyutla ilgili bulgular analizlere dâhil edilmemiştir. Diğer alt boyutlarla ilgili hesaplanan iç tutarlılık katsayıları .73 ile .88 arasında değişmektedir. Parametrik test koşullarını sağlamaması sebebiyle toplanan veriler Kruskal Wallis H ve Mann Whitney U testleri kullanılarak analiz edilmiştir. Öğrencilerin OB puanlarının orta düzeyde olduğu belirlenmiştir. Analiz sonuçlarına göre OB düzeyi puan sıra ortalamalarının cinsiyete göre anlamlı bir farklık göstermediği tespit edilmiştir. Sınıf düzeyine göre durum değiştirme alt boyutunda birinci sınıf öğrencilerinin OB düzeyi üçüncü sınıf öğrencilerinin OB düzeyinden yüksek bulunmuş, diğer alt boyutlarda anlamlı farklılık tespit edilmemiştir. Ekonomik durum algısına göre OB düzeyi puan sıra ortalamaları arasında nüksetme ve çatışma alt boyutlarında anlamlı farlılıklar bulunmuştur. Ekonomik durumunu orta ve kötü olarak algılayanların OB puan sıra ortalamaları daha yüksektir. Akademik başarı durumuna göre durum değiştirme alt boyutu dışındaki diğer tüm alt boyutlarda OB puan sıra ortalamaları arasında anlamlı farlılıklar tespit edilmiş, akademik başarısı düşük olan öğrencilerin puan sıra ortalamaları daha yüksek bulunmuştur. Mevcut çalışmada, aile ekonomik durumu ile akademik başarının OB puanlarında önemli bir değişken olduğu anlaşılmıştır. Bu çalışmadan elde edilen bulgular akademik başarıyı olumsuz yönde etkileyen hususların tespit edilmesi ve giderilmesinin yanı sıra oyun bağımlılığını azaltamaya da katkı sağlayabilir.

Comparative Analysis of the Effectiveness of Individual and Group Forms of Language Learning in the Zone of Proximal Development in Middle School Age
Authors: Chernov D.N.
Published: December 2022

The research is devoted to the problem of organization of language learning in the zone of proximal development by means of actualization of language intuition. Hypotheses are tested: training to translate texts containing quasi-words in the zone of proximal development leads to growth of the level of language competence; under specific conditions, training in a small group in the zone of proximal development is no less effective compared to the individual teaching of each pupil. The sample consisted of 74 children under 12 years old. An intergroup two-factor experiment was conducted (presence / absence of training — individual / group work). The author's technique "Translation of texts consisting of quasi-words into Russian " was used. The teacher's assistance in translating quasi-words into Russian in the form of reflexive cooperation with the child, encouraging him to recreate the integral meaning of the text in combination with checking the meanings of quasi-words for compliance with the morphological / grammatical context is the optimal strategy for teaching using quasi-texts. Training leads to improved skills of completing unfinished words in sentences in Russian. The effectiveness of training in a small group indicates the possibility of taking into account the zone of proximal development of each child in group work.

Published: December 2022

A communication technology which enables the information exchanges between vehicles to support intelligent transportation system is the characteristic of vehicular ad hoc network (VANET). The vast applications of VANET including transportation safety, traffic management, and passenger amenities are also followed by some technical challenges. The rapid topology changes and high nodes mobility are the main source of the challenges. One of the prominent challenges is the handover decision, especially in vehicle to vehicle (V2V) communication. In this paper, handover decision method for V2V VANET is proposed using fuzzy system. The proposed method adjusts the value of received signal strength (RSS) hysteresis adaptively using fuzzy system so that the proposed handover decision method is called fuzzy adaptive hysteresis (FAH). To adjust the value of hysteresis, fuzzy system utilizes RSS value, speed difference, and connected time as the input. Based on the simulation results, the proposed method can reduce handover rate as well as maintaining the higher value of signal to noise ratio (SNR) average.

Published: December 2022

The development of error correcting codes has been a major concern for communications systems. Therefore, RS and BCH (Reed-Solomon and Bose, Ray-Chaudhuri and Hocquenghem) are effective methods to improve the quality of digital transmission. In this paper a new algorithm of Chien Search block for embedded systems is proposed. This algorithm is based on a factorization of error locator polynomial. i.e, we can minimize an important number of logic gates and hardware resources using the FPGA card. Consequently, it reduces the power consumption with a percentage which can reach 40 % compared to the basic RS and BCH decoder. The proposed system is designed, simulated using the hardware description language (HDL) and Quartus development software. Also, the performance of the designed embedded Chien search block for decoder RS\BCH (255, 239) has been successfully verified by implementation on FPGA board.
A Tutela Autônoma do Direito à Imagem
Authors: Zanini Leonardo Estevam de Assis
Published: December 2022

O presente artigo tem como objetivo o estudo da imagem como um direito autônomo. Trata-se de pesquisa que utiliza metodologia descritiva e dedutiva, baseada fundamentalmente em revisão bibliográfica e na investigação da legislação e da jurisprudência. O texto inicialmente destaca que o surgimento e o desenvolvimento da técnica fotográfica foi fundamental para que direito à imagem passasse a ter relevância jurídica. Deixa claro que o direito à imagem protege um bem jurídico autônomo, que não pode ser confundido com outros direitos, como é o caso da honra e da privacidade. O trabalho também analisa dois julgados de tribunais brasileiros, o que é feito para se constatar a dificuldade de compreensão sobre a tutela do direito à imagem. Os resultados alcançados demonstram que a interpretação equivocada da Constituição Federal e do Código Civil, muitas vezes realizada pela doutrina e pelos tribunais, pode levar a resultados bastante danosos. Por isso, para que se garanta a tutela autônoma do direito à imagem, é necessária a releitura do art. 20 do Código Civil em conformidade com Constituição Federal.

Published: December 2022

A atuação de agentes políticos influencia a definição e os rumos da agenda governamental e, consequentemente, a formulação de políticas públicas. Portanto, tendo em vista a importância desses agentes para o rumo adotado nas políticas públicas, pretende-se analisar a sua participação na Medida Provisória nº 746/2016, referente à Reforma do Ensino Médio. Desse modo, a pesquisa objetiva identificar os agentes do setor público e privado - em especial, os grupos empresariais educacionais - que atuaram na formulação desta política educacional; compreender a relação estabelecida entre ambos os agentes; e, por fim, construir uma rede de políticas públicas, mapeando as interações que os agentes estatais estabeleceram entre si e com os atores externos à instituição de modo a identificar o papel dos agentes privados na nova configuração de governança possibilitada pelas redes. Desse modo, a proposta metodológica foi pautada no estudo qualitativo e quantitativo com base nos pressupostos teórico-metodológicos de redes de políticas públicas. Para isso, foi feito o levantamento documental de fontes primárias e secundárias, o qual consistiu, respectivamente, na leitura da MP nº 746/2016 e das 568 emendas propostas, além da votação nominal ao final do processo de formulação desta política pública, e na coleta de informações nas notícias veiculadas no jornal Folha de São Paulo entre o período de 2016 a 2017. A partir dos resultados obtidos em ambas as etapas da pesquisa, é possível perceber uma aproximação entre o discurso adotado pelos parlamentares nas emendas propostas por eles, em seu posicionamento durante a votação no Senado para que a MP nº 746/2016 se convertesse em lei e nas interações que estabeleceram entre si durante o processo.

Published: December 2022

Este estudo teve como objetivo discutir saberes outros relacionados ao tempo e ao espaço a partir de produções de autoria de professores indígenas, em materiais voltados para as escolas indígenas. A partir desse estudo, pretendeu-se adentrar em outros campos epistemológicos, com a finalidade de discutir a questão dos saberes indígenas como forma de luta pela preservação e manutenção das práticas e saberes culturais. Esse movimento propõe um processo de decolonialidade dos saberes, ou seja, afirmação dos conhecimentos, culturas e saberes provenientes de fontes diferentes das produzidas no ocidente. Desse modo, o estudo procura trazer tanto problematizações sobre a educação escolar indígena brasileira e o papel de movimentos de resistência, como a Etnomatemática, em seu ensino, como também a divulgação da produção de autoria desenvolvida por professores indígenas. Devido à grande quantidade de povos, cada um com sua especificidade e estabelecidos em diferentes estados, os materiais trazidos pela pesquisa retratam narrativas e conhecimentos de diversos povos indígenas, mostrando ainda mais a grande riqueza que essas comunidades possuem.

Authors: GÜLHAN Barış , YANGILAR Filiz
Published: December 2022

The study evaluated the antibacterial effect of stinging nettle extract by the liquid microdilution method to obtain quantitative results. Unlike other studies in the literature, MIC and MBC values showing bacteriostatic and bactericidal effects were investigated for four different bacterial concentrations. Six pathogen strains were studied, including Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Streptococcus pneumoniae ATCC 45615, Klebsiella pneumoniae ATCC 70063, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853 and different levels of antimicrobial effects were determined. While the extract does not affect the Klebsiella pneumoniae ATCC 70063 strain at any level, Pseudomonas aeruginosa ATCC 27853 in strains 1.5x105 and 1.5x104 MIC values were found at concentrations, no effect was observed at the MBC level. While MIC and MBC values were found at the concentrations of Staphylococcus aureus ATCC 29213 except for the 1.5x107 concentration, the remaining standard strains had different MIC and MBC values at all concentrations. The standard strain Streptococcus pneumoniae ATCC 45615 was the most effective with the extract's lowest MIC and MBC values. This study showed that nettle extract (Urtica dioica) would contribute to the research results in the scientific literature on its antimicrobial effect.

In this study, our aim is to predict the compositions of zinc electroplating bath using machine learning method and optimize the organic additives with NSGA-II (Non-dominated Sorting Genetic Algorithm) optimization algorithm. Mask RCNN was utilized to classify the coated plates according to their appearance. The names of classes were defined as ”Full Bright”, ”Full Fail”, ”HCD Fail” and ”LCD Fail”. The intersection over union (IoU) values of the Mask RCNN model were determined in the range of 93–97%. Machine learning algorithms, MLP, SVR, XGB, RF, were trained using the classification of the coated panels whose classes were detected by the Mask RCNN. In the machine learning training, the additives in the electrodeposition bath were specified as input and the classes of the coated panels as output. From the trained models, RF gave the highest F1 scores for all the classes. The F1 scores of RF model for ”Full Bright”, ”Full Fail”, ”HCD Fail” and ”LCD Fail” are 0.95, 0.91, 1 and 0.80 respectively. Genetic algorithm (NSGA-II) was used to optimize the compositions of the bath. The trained RF models for all the classes were utilized as the objective function. The ranges of organic additives, which should be used for all the classes in the electrodeposition bath, were determined.

The Effect of Periodic Inspection and Safety Criteria on the Service Life of Steel Construction Conveyors
Authors: GÜVEN Ersin
Published: December 2022

Steel construction structures are seen in many different applications in our country and in the world. However, the periodic maintenance of these steel construction products is explained by national and international laws and regulations. According to the relevant regulation in our country, it is obligatory to carry out periodic inspections of these constructive structures, which are referred to as machinery and equipment, once a year. As in many facilities, it is obvious that these structures are the main elements of the facility and will be used throughout the life of the facility. It is not clear under which conditions these structures, which are generally produced using structural steels and which are connected by welding or bolts, will be examined in the periodic inspections. As a result of the research on the lifetime of general structural steels, it has been proved by many researchers that these structures have an infinite life if they reach the number of million repetitions. However, the life of welding or bolts, which are the connecting elements of the structure, remains uncertain. In this study, accident breaking studies were carried out by detailing the damage due to a tragic accident in a steel construction that has served for about 36 years. By keeping company and personal information confidential, the steel structure and bolt connections of the construction were examined in terms of strength, hardness and microstructure, and the results were detailed.
Archaeometric Investigation of Gold Coins (Byzantine Period, Romanus Iii) By Means of Portable Xrf: Characterization and Comparison
Authors: BAYAZİT Murat , ŞEKER Nesrin
Published: December 2022

Some of the ancient materials in museums can only be examined on-site, which requires in-situ analysis techniques. Coins made of precious metals are one of such materials and portable X-ray fluorescence (p-XRF) spectrometry is one of the most preferred technique for gold and silver-based coins that need to be characterized in situ and non-destructively. In this study, a detailed archaeometric investigation was carried out for the gold coins which were unearthed after the excavations in Melik Ahmet Street (Diyarbakır, 1992) and brought to Directorate of Diyarbakır Museum through confiscation. The chemical compositions of the samples were specified by means of portable XRF which was applied on 45 gold coins of the Romanus III period. The main element in the composition was found as gold detected as 93.89% in average. Silver was the most abundant element after gold, however the highest silver rate did not exceed 9% (5.25% in average). Copper and iron were identified respectively in 12 coins (Cu: 1.05-2.46%) and 18 coins (Fe: 0.87-6.5%). Manganese, nickel, titanium, lead, iridium and osmium were seen in one sample each. The hierarchical clustering analysis applied with gold-silver-copper-iron and gold-silver suggested three different groups. The hierarchical clustering analysis was also applied considering the p-XRF data achieved in this study (belonging to the Romanus III period), solidus samples belonging to six Byzantine period emperors, and for the hollow coins belonging to four Byzantine period emperors. Taking into account the distribution, classification and the variations, the coins of different emperor periods were compared.

Data from blood culture, urine test, and other diagnostic procedures were extracted from the records. Information on age, sex, the most common cause of referral, culture and positive culture, mitral valve, tricuspid and pulmonary valve involvement, underlying condition of injecting drug addiction, duration of hospitalization, clinical symptoms, type of treatment, response to Treatment, status of hospital discharge and mortality rate of patients were collected and then analyzed.Results: Of all patients, 14 (43.75%) were male and 18 (56.25%) were female. The mean age of patients was 55.6±9.4 years with a range of 21-72 years old. Patients were treated at an average of 2.2±1.4 weeks. 9 patients (28.12%) had skeletal-muscular manifestations. 26 patients (81.25%) had fever. The most prevalent microorganism was klebsiella with 71.87% that was sensitive in 13 patients (56.5%) to methicillin.Conclusions: Fever with musculoskeletal manifestations in young men with a history of injectable addiction is a common manifestation of infectious endocarditis.
Spirometry assessment of interstitial lung disease patients and correlation with its clinical and radiological profile
Authors: Balas Zeel C. , Jotkar Sushama
Published: December 2022

Background: Interstitial lung diseases (ILD) are a diverse set of lower respiratory tract illnesses that are defined by both abrupt and persistent inflammation as well as a largely irreversible and continuous progression of fibrosis in the interstitium and the walls of the alveoli. This study focuses on non-invasive techniques for clinically and radiographically confirmed situations. Since most patients refuse surgical or transbronchial lung biopsies and are in respiratory difficulty, an alternate method is preferable. Spirometry tests are often used as diagnostic aids. This study compares spirometry in ILD patients with their radiological and clinical features.Methods: In this prospective observational study, 50 ILD patients who were diagnosed on the clinical and radiological grounds included. A detailed history of illness was obtained and noted. All patients were examined clinically and underwent basic investigations. All patients were performed 6 MWT O2 saturation and spirometry. Correlation between spirometry findings and clinical and radiological profile was done.Results: The study group of 50 patients with ILD, idiopathic pulmonary fibrosis was the most common cause of ILD consists of 32 patients performing 64% of the study group. Average duration of symptoms in ILD patients in this study was 5.46±5.49 months. The mean age of the patients was 61.58±12.92 years ranging from 27 to 88 years with 27 (54%) male and 23 (46%) female. Cough and dyspnoea were the most common features at presentation in our study group, present in almost all the patients. Crepitations were present in 41 (82%) patients. Most common chest X-ray feature was reticular opacities which was present in 24 (48%) patients. Ground glass opacity in high-resolution computed tomography (HRCT) was seen in 33 (66%) patients. Most common spirometry pattern seen in our study was Restrictive pattern which was present in 42 patients. In ILD patients, mean values of FEV1% was 59.2±20.33, FVC% was 60.76±25.45, FEV1/FVC was 100.86±20.12.Conclusions: Idiopathic pulmonary fibrosis is the most common and chronic hypersensitivity pneumonitis along with cryptogenic organizing pneumonia are the second common ILD in our study. The underdiagnosis of interstitial lung disease is due to a lack of knowledge among doctors. Therefore, spirometry and 6MWT O2 saturation should be performed in all patients presented with complaints of chronic cough and breathlessness as screening tool and then HRCT chest and biopsy can be done for confirmation of diagnosis. So early diagnosis and treatment of ILD patients is possible with use of spirometry.

Published: December 2022

Background: Haemoglobin measurement in antenatal care can help in timely detection and treatment of anaemia, which is a major contributory factor to maternal mortality in developing countries. The transport of samples for haemoglobin assessment may delay the treatment, resulting in preventable deaths. Haemoglobin measurement by point of care testing (POCT) devices is easy, quick and less invasive. There are very few studies which compare the capillary blood haemoglobin using point of care devices with venous blood samples. This study was conducted to compare capillary blood haemoglobin using POCT device with venous blood haemoglobin using haematology analysers in antenatal Indian females.Methods: One hundred pregnant women were recruited during their first trimester antenatal visits. Hemoglobin by finger prick capillary sample (POCT) was compared with haemoglobin of venous sample analysed by the haematology analyser (Beckman coulter) which was considered as gold standard. Intraclass correlation co-efficient based on Bland Altman analysis was computed using SPSS v21. A p value less than 0.05 was considered statistically significant.Results: The intraclass correlation coefficient of 0.97 was recorded with central laboratory reference standard, with a mean difference of -0.481 gm% and -0.482 gm% by capillary and venous blood samples, respectively (p<0.0001).Conclusions: A good agreement between capillary blood haemoglobin (POCT device) and venous blood (haematology analyser) was achieved.

Published: December 2022

Background: Lumbar spinal stenosis is the most frequent indication for spine surgery. The x-ray and MRI are the choice of investigation. Justified use of radiography can be cost effective in the management of lumbar spinal stenosis. Objective was to evaluate and compare the sensitivity and specificity of the plain x-ray and MRI in the diagnosis of the lumbar spinal stenosis.Methods: A multicenter cross sectional analytical study was carried out from July 2021 to August 2022 on 70 patients of both sexes aged more than 25 years with chronic low back pain.  A descriptive analysis was performed for all data.Results: In the MRI, 35 (50.0%) cases had diskogenic spinal canal stenosis and 24 (34.3%) had both diskogenic and non diskogenic spinal canal stenosis. The validity of MRI evaluation for only diskogenic spinal canal stenosis was correlated, where the calculated values of plain x-ray were: sensitivity 80.0%, specificity 60.0%, accuracy 77.5%, positive predictive value 93.3% and negative predictive value 30.0%. The validity of MRI evaluation for both diskogenic and non diskogenic spinal canal stenosis was correlated, where the calculated values of plain x-ray were sensitivity 83.3%, specificity 66.7%, accuracy 80.0%, positive predictive value 90.9% and negative predictive value 50.0%.Conclusions: Plain x-ray is a useful and reliable diagnostic modality for the evaluation, assessment and the subsequent appropriate management of lumbar spinal stenosis.

Background: COVID-19 infection, discovered in Wuhan, China, engulfed vast population in most of the countries in a very short span, ranging from aymptomatic infection to acute respiratory distress syndrome, multiorgan failures and death. Individual studies on serum lactate dehydrogenase and albumin showed association with severity of disease. The purpose of present study is intended to predict the association of combined lactate dehydrogenase (LDH) to Albumin ratio with severity of COVID-19.Methods: A retrospective observational study was carried on already confirmed cases of covid 19 infection from July, 2021 to December, 2021 in Gandhi hospital, Secunderabad. History, clinical features and laboratory findings including LDH: Alb ratio was noted. Cases with known history of carcinomas, chronic kidney disease, chronic liver/lung disease, coronary artery disease, alcoholics were not included. Cases were divided into mild, moderate and severe based on National clinical management protocol for COVID-19. Data was analyzed using SPSS/Medcalc software.Results: LDH and LDH: Alb ratio was significantly raised with the severity of the disease. The AUC in ROC analysis of LDH: Alb ratio was 0.75 compared to 0.71 and 0.62 individually for LDH & Alb respectively; indicating ratio was superior to that of individual parameters.Conclusion: The present study shows significant correlation between LDH: Alb ratio with severity of COVID-19 infection. LDH: Alb ratio could be an easily available tool to predict COVID-19 severity.

Background: Fracture shaft of femur is a common fracture in children, with treatment from conservative in form of skin traction to intramedullary nailing depending on age. Conservative treatment is mostly used upto six years of age, while for children more than 12 years surgery is usually preferred. We extended conservative in form of hip spica cast till 10 years of age. This study evaluates results of skin traction followed by spica cast in children upto 10 years of age.Methods: Study was done in GMC Doda from April 2019 to March 2022. 47 patients were enrolled for study, patients were initially given skin traction to get alignment which was followed by spica cast. Patients were evaluated at 3, 6, 9 and 12 weeks, final follow up was done at 6 months.Results: Out of 47 children, 4 patients were lost to follow up. Average age of children was 5.83 years. Mode of trauma was mostly RTA or fall from height. Average duration of traction was 9.14 days and average stay in hospital was 11.5 days. Average union time was 8.36 weeks. We had significant limb length discrepancy or angulation in 6 (13.9%) of our patients.Conclusions: skin traction followed by spica cast gives good results in fracture shaft femur in children upto 10 years of age.

Primary hyperparathyroidism occurs due to parathyroid adenoma, which as initial presentation in most cases includes recurrent nephrolithiasis (10-25%). Giant cell tumors (GDD) also called osteoclastomas or brown tumors affect the second decade of life and are currently a rare manifestation of primary hyperthyroidism. The incidence of lesion appearance in the maxillary bones is 4.5%. We presented the case of a 36 year old female patient with history of hypertension, who developed an increase in volume in the right maxillary region of 4×3 cm, with incapability of complete occlusion of dental arch, solid dysphagia, biopsy was performed with peripheral giant cells granuloma as a result, PTH serum levels were requested, with result of 1175 pg/ml and serum calcium of 13.24 mg/dl. Parathyroid gammagram was performed with hyperfunctioning parathyroid tissue. Patient underwent a selective parathyroidectomy. She had an adequate postoperative evolution and was discharged without complications. The patient had adequate follow up by head and neck surgery in external consultation, serum calcium 7.66 mg/dl, decrease of volume in right maxillary region to 3×3 cm; pathology report with parathyroid adenoma. Surgical treatment of brown tumor is still pending by the maxillofacial surgery department.

3 years ago, 38-year-old male, with no relevant personal pathological history, began to present exertional dyspnea, gastroesophageal reflux, retrosternal pyrosis, dyspepsia and postprandial abdominal distension after a traffic accident. A study protocol was initiated, where cabinet studies documented elevation of the left hemidiaphragm was documented. A minimally invasive approach was performed with the finding of elevation of the left hemidiaphragm of approximately 8 cm in relation to the contralateral diaphragm without evidence of paraesophageal hernia. Mayo type left diaphragmatic plication was performed with non-absorbable suture (polypropylene 1) without complications. With favorable evolution, he started the oral route 8 hours postoperatively, and was discharged 48 hours after surgery due to clinical improvement and without gastroesophageal reflux. Surgical plication of the affected hemidiaphragm is successful in carefully selected patients with severe symptoms thought to be due to unilateral diaphragmatic paralysis. Studies demonstrate improvement in several parameters, including lung and respiratory muscle function, exercise endurance, blood gas exchange, and possibly dyspnea.
