Authors: Sunil B , Rajanna S.
Published: December 2020

The main aim of the research work is to examine the fracture toughness of the dual phase steels prepared using the intermediate quenching method. The ferrite-martensite dual phase (DP) steel is produced using low carbon micro alloyed steel by the heat treatment and intercritical quenching technique using various intercritical temperatures such as 740,760,780,800 and 820oC. The samples of the produced dual phase steel are analyzed for their microstructure using optical microscope. The fracture toughness investigations for the dual phase steel have been carried out using ASTM standard testing procedure. From the results it is observed that the fine distribution and equal volume fraction of ferrite and martensite phases at 780oC. The effect of which, the A780 steel has demonstrated excellent fracture toughness which is the result of intermediate quenching technique. The fractography analysis it is clear that the ductile initiated brittle fracture is occurred which is due to the increased hard martensite phase and the increment in the stress accumulation at the ferrite which also leads to the higher elongation.

Published: December 2020

Limited by the mechanical properties of materials, silicon (Si) carbide insulated gate bipolar transistor (IGBT) can no longer meet the requirements of high power and high frequency electronic devices. Silicon carbide (SiC) IGBT, represented by SiC MOSFET, combines the excellent performance of SiC materials and IGBT devices, and becomes an ideal device for high-frequency and high-temperature electronic devices. Even so, the thermal fatigue failure of SiC IGBT, which directly determines its application and promotion, is a problem worthy of attention. In this study, the thermal fatigue behavior of SiC-IGBT under cyclic temperature cycles was investigated by finite element method. The finite element thermomechanical model was established, and stress-strain distribution and creep characteristics of the SnAgCu solder layer were obtained. The thermal fatigue life of the solder was predicted by the creep, shear strain and energy model respectively, and the failure position and factor of failure were discussed.

Published: December 2020

Sosyal altyapı alanları yoğun yapılaşma özelliği sergileyen günümüz kentsel yerleşmelerinde önemli kent içi boşlukları oluşturmaktadır. Kentlerimizin yüksek yoğunluklu yapılaşma dokuları ve bu doku içerisinde kapasite ve mekansal dağılım açısından yetersizlikleri gözetildiğinde, sosyal altyapı alanlarının öncelikle mevcut stokunun korunması gerektiği açıkça ortadadır. Öte yandan park, spor alanı, ilkokul gibi sosyal altyapı alanları, afet durumunda halkın toplanma amaçlı kullanabilmesi için uygun, farklı nitelikteki arazi kullanım türlerini oluşturmaktadır. Bu nedenle, potansiyel toplanma alanı niteliği taşıyan sosyal altyapı alanlarının korunması ve arttırılması, bu alanların afet durumundaki işlevselliği açısından da büyük önem arz etmektedir. Bu alanların korunabilmesi ve geliştirilebilmesi imar planı kararlarına, bu planlarda afet sorununa karşı gösterilen duyarlılığa ve toplanma alanlarına yönelik farkındalık durumuna bağlıdır. Bu çalışmada, afet durumunda toplanma alanı olarak kullanılabilme potansiyeline sahip sosyal altyapı alanları mercek alına alınmış ve bu alanların mevcut imar planlarındaki durumları incelenmiştir. Bu kapsamda çalışmada, örnek alan olarak seçilen İzmir kentsel yerleşik alan sınırı içinde yürürlükte olan uygulama imar planı kararları ile sosyal altyapı alanlarının mevcut durumları karşılaştırmalı olarak incelenmiş ve değerlendirmeler yapılmıştır. Elde edilen sonuçlara göre, sosyal altyapı alanlarının yaklaşık %80’ninin uygulama imar planı kararlarında mevcut durumu korunurken, %20’sinin uygulama imar planı kararlarında kısmen korunduğu ve/veya başka bir arazi kullanım kararına dönüştürülerek mevcut durumunun korunmadığı saptanmıştır. Bu kapsamda şehir planlama ve afet yönetimi disiplinlerinin ortak paydasını oluşturan sosyal altyapı alanlarına ilişkin geliştirilebilecek politikaların kentlerin afetlere karşı dirençliliğini artırma sürecindeki önemi uygulama imar planları bağlamında vurgulanmıştır.

Published: December 2020

Introdução: No início do século passado, o câncer já se caracterizava como uma das doenças crônico-degenerativas mais letais e começou a demandar mais atenção dos governos. Portanto, alguns países empreenderam novas medidas políticas, como o aumento de investimentos científicos em busca de uma cura. Objetivo: Este artigo procura evidenciar as características dos conteúdos das matérias jornalísticas sobre o câncer nos jornais brasileiro e norte-americano Correio da Manhã e The New York Times, nas décadas de 1930 e 1940, através da análise das notícias publicadas em quatro anos selecionados (1931, 1932, 1948 e 1949). Método: Foram realizadas pesquisas no acervo documental da Biblioteca Nacional e no acervo digital do The New York Times. Em paralelo, também foi realizada uma análise do que foi publicado sobre o tema câncer nos periódicos científicos, acessível através do portal do PubMed, durante a mesma época. Resultados: Enquanto, no Correio da Manhã, foram identificadas 56 reportagens sobre o tema no período estudado, no jornal americano, foram identificadas 540 notícias, ou seja, quantidade praticamente dez vezes superior. Conclusão: Os achados demonstram uma imprensa brasileira tímida e, por vezes ingênua, diante de promessas de curas milagrosas, como pomadas contra o câncer de pele. Enquanto isso, a mídia norte-americana priorizava abordagens sobre investimentos para a pesquisa da doença, destacava as conferências de cientistas especialistas no assunto e até o uso de experimentação animal na pesquisa do câncer; embora, em certas ocasiões, também tenha apostado em inovações científicas que a história mostrou como iniciativas infrutíferas.

Published: December 2020

Introdução: O tromboembolismo venoso é uma condição potencialmente fatal e frequente no paciente oncológico. Muitas vezes, a anticoagulação é inviável, e a colocação do filtro de veia cava (FVC) torna-se uma opção. A indicação clínica, entretanto, é controversa e gera alto custo. Objetivo: Descrever as características demográficas, clínicas e epidemiológicas dos pacientes com colocação de FVC e seu impacto na sobrevida global. Método: Estudo de coorte retrospectiva com pacientes em tratamento oncológico no INCA, que tiveram FVC implantado de janeiro/2015 até abril/2017. Na análise de sobrevida global em cinco anos, foram considerados o tempo entre o diagnóstico de câncer e o óbito por qualquer causa. Realizaram-se análise descritiva, estimativas de sobrevida (Kaplan-Meier) e regressão de Cox. Resultados: Foram incluídos 74 pacientes com média de idade 54 (+-15) anos. Em sua maioria, apresentavam tumores ginecológicos (52,7%) e digestivos (20,3%). O tempo mediano entre o diagnóstico de câncer e a colocação do FVC foi de 3,48 meses (0-203). No seguimento, foram observados 40 óbitos (54,1%) com mediana de tempo de 25 meses (IC 95%; 1,76-47,32). Na análise ajustada, verificou-se risco 5,63 vezes maior de morrer nos pacientes com colocação do FVC em até seis meses após o diagnóstico de câncer (HR=4,99; IC 95%; 2,20-11,33; p<0,001), e risco 2,47 vezes maior entre aqueles que não fizeram no pré-operatório (HR=2,47; IC 95%; 1,08-5,66; p=0,032). Conclusão: A colocação do FVC foi realizada com maior frequência em pacientes com tumores ginecológicos e em até seis meses após o diagnóstico de câncer foi associada a maior risco de óbito.

The impact of risks on organizations' performance, the effectiveness of projects and business processes is constantly increasing, and the level of risk is often a determining factor in strategic decision-making. However, according to international statistics, only 16.2% of projects are recognized as successful — performed on time and within the budget, and 52.7% of projects are implemented with an excess of budget, on average by 89%. In order to improve the efficiency of integrated risk management systems, for the first time, an attempt has been made to take into account the synergy, resulting from the digital integration of many heterogeneous elements of the management system and the uncertainties of existing factors into a single socio-economic system based on the priority of the subjective, which are associated with concepts such as non-linearity, uncertainty and randomness. The mutual influence and adjustment the elements of a integrated management system to the purpose and conditions of operation means, that the system relies on a distributed quality and performance assessment, taking into account the uncertainties of existing risk factors. The real transport infrastructure investment project shows the benefits of a synergistic approach and the digital method of integrated bundles, its software implementation on the Microsoft Excel platform in ensuring risk management and achieving the reliability of estimates based on uncertainty and risk.
Management of Economics and State "Bottom"
Authors: Solozhentsev E. D.
Published: December 2020

The scientific problem of economics “Managing the quality of human life” is formulated on the basis of artificial intelligence, algebra of logic and logical-probabilistic calculus. Managing the quality of human life is represented by managing the processes of his treatment, training and decision making. Events in these processes and the corresponding logical variables relate to the behavior of a person, other persons and infrastructure. The processes of the quality of human life are modeled, analyzed and managed with the participation of the person himself. Scenarios and structural, logical and probabilistic models of managing the quality of human life are given. Special software for quality management is described. The relationship of human quality of life and the digital economy is examined. We consider the role of public opinion in the management of the “bottom” based on the synthesis of many studies on the management of the economics and the state. The bottom management is also feedback from the top management.

La sabbia naturale viene estratta con metodi minerari, anche per la produzione di sabbie artificiali. La sabbia è ampiamente utilizzata in diverse aree. Come aggregati di costruzione; industrie di trasformazione dei materiali; trattamento delle acque e delle acque reflue. L’Areal della società Morro Branco, dove sono stati raccolti i campioni di sabbia, si trova intorno alla sede del comune di Porto Grande. Il comune di Porto Grande ad Amapá si trova al centro dello stato a 108 chilometri dalla capitale Macapá. L’obiettivo di questa ricerca era quello di effettuare l’analisi tecnologica del materiale di Areal Morro Branco, Porto Grande, Amapá, per frazionamento. La sabbia è stata rimossa da una zona sabbiosa nel comune di Porto Grande – AP con l’uso di utensili a mano per la raccolta. Sono stati raccolti 03 (tre) campioni provenienti da punti diversi con composizione diversa, a causa dell’esistenza di materia organica nella sua composizione. Il silicato di sodio con una concentrazione del 10% e il bromoforme sono stati utilizzati per la degradazione della materia organica del campione. Queste procedure sono state determinate nel campione secco in forno per 24 ore a circa 110° C e la percentuale di umidità (%U), questo, è stata determinata anche nel campione originale. E’ stato verificato attraverso i test e le procedure eseguite che l’umidità della sabbia dell’Areal Morro Branco è influenzata dalla materia organica derivante dalle aree forestali e dalle risorse idriche dei dintorni dell’Areal. La granulometria dei punti da cui la sabbia è stata raccolta nella sabbia ha caratteristiche di grano angolato e sottoangolo. Con l’aiuto della densità bromoforme, è stato possibile rendersi conto che la sabbia da cui è stato raccolto il campione presenta aggregati di quarzo, feldspato con una densità inferiore a 2,89 g/cm3. È stato suggerito che la sabbia possa anche avere derivati minerali della sabbia con densità maggiore di 2,89 g/cm3, che sono olivina e pirosseno.

Amaç: Bu çalışmada, tip 2 diyabetli bireylerde serum D vitamini, kalsiyum ve magnezyum düzeyleri ile beslenme durumu arasındaki ilişkinin değerlendirilmesi amaçlanmıştır.

Bireyler ve Yöntem: Çalışma, Hakkari Devlet Hastanesi Dahiliye polikliniğinde takip edilen, 25-45 yaş arası, 51 tip 2 diyabetli ve 51 sağlıklı bireyle yürütülmüştür. Bireylerin demografik özellikleri araştırmacılar tarafından hazırlanan anket ile sorgulanmıştır. Diyetle magnezyum ve kalsiyum alım miktarları 24 saatlik besin tüketim sıklığı anketi ile elde edilmiştir. Bireylerin antropometrik ölçümleri (vücut ağırlığı, boy uzunluğu, bel çevresi) alınmış ve serum D vitamini, iyonize kalsiyum ve magnezyum düzeyleri analiz edilmiştir. D vitamininin esas kaynağı güneş ışınları olduğu için çalışma aynı mevsim içerisinde yapılmıştır.

Bulgular: Çalışmaya 48 erkek (28 tip 2 diyabetli) ve 54 kadın (23 tip 2 diyabetli) birey katılmıştır. Tip 2 diyabetli ve sağlıklı erkek bireylerin günlük kalsiyum alımlarının sırasıyla %10.7, %45.0’inin <1000 mg olduğu saptanmıştır (p<0.05). Tip 2 diyabetli (%84.3) ve sağlıklı bireylerin (%86.7) serum D vitamini düzeyinin çoğunlukla eksiklik düzeyinde olduğu (p>0.05); iyonize kalsiyum (sırasıyla %82.3, %84.3) (p>0.05) ve magnezyum (sırasıyla %82.3, %64.7) (p<0.05) düzeylerinin ise normal sınırlarda olduğu saptanmıştır. Tip 2 diyabetli bireylerin beden kütle indeksi (BKİ) değeri 25-29.9 kg/m2 arasında olanların ve tip 2 diyabetli kadınların bel çevresi ≥88 cm olanların serum D vitamini düzeyleri sağlıklı bireylerden daha düşüktür (sırasıyla p=0.002; p=0.009). Sağlıklı bireylerin magnezyum alımı ile vücut ağırlığı (r=0.353) ve BKİ değerleri (r=0.282) arasında pozitif anlamlı ilişki saptanmıştır.

Sonuç: Tip 2 diyabetli bireylerin serum D vitamini, kalsiyum ve magnezyum düzeylerinin düşük olduğu, yüksek BKİ ve bel çevresi değerlerinin hem tip 2 diyabetle hem de düşük serum D vitamini düzeyleri ile ilişkili olduğu gözlenmiştir.

Until 6 September 2020, there were 190,665 cases in Indonesia, and it was in the third rank of most cases in the Asian region. It is important to determine the criteria of return to work for healthcare workers with Covid-19 positive in Indonesia. This case report discussed a female patient, 32 years old with chief complaint of fever and itchy throat since 2 days ago. She is a health care worker in the hospital, with a history of treating patients with positive confirmation of Covid-19 for 2 days in the ordinary ward before the case was confirmed with a history of contact approximately 5 days ago. The patient was diagnosed with positive confirmation of Covid-19 and was required for self-isolation. The patient still had positive results of RT-PCR Covid-19 up to the third examination in 30 days after the initial RT-PCR testing, although received specific antiviral treatment with oral oseltamivir and oral supplementation. Based on growing evidence that Sars-Cov-2 may not infectious for more than ten days in the mild-moderate disease, this case report is strengthening the use of symptom-based strategic approach to determine when to return to work in Indonesian healthcare workers with positive COVID-19.

Testicular torsion (TT) is an emergency in urology that happens because of the spermatic cord’s rotation. Decreased of overall sperm parameters after TT often happens in which can endanger the patient’s fertility status. Approach on how to salvage the testicle and to prevent unwanted complications remains as the doctor’s greatest priority. We report a case of oligoasthenoteratozoospermia after surgical detorsion without orchidectomy in testicular torsion. A 19-year-old male, presenting with sudden, progressive, and continuous pain in the right testicle for 4 hours. The right testicle was larger in volume on physical examination, there were a negative phren sign and negative cremasteric reflex. Gray scale ultrasound without Doppler showed changes suggestive of testicular torsion. Emergency surgery revealed a dark-bluish right testicle with a 360o rotation of the spermatic cord. Detorsion without orchidectomy was performed with clinical judgment hoping for the restoration of testicular viability. Sperm analysis was done after one month and oligoasthenoteratozoospermia was found. Although some patients experience decreased overall sperm parameters after TT that perhaps making them infertile, interestingly there is no difference in pregnancy rates among couples with TT men when compared to the general population. The best testicular salvage surgery method to prevent testicular atrophy also has not been determined yet. Thus, the patient should be carefully counseled about the good outcome of pregnancy rate and the chance for testicular atrophy, regardless of what is the surgical choice.

Telomer merupakan bagian penting dalam penyimpanan informasi dalam kromosom kita. Setiap pembelahan sel, telomer akan mengalami pemendekkan dan akan memberikan suatu signal bahaya pada saat mencapai batas tertentu. Selain dari pemendekkan sel, ada berbagai macam hal yang bisa menyebabkan pemendekan telomer. Gaya hidup sedenter, kebiasaan merokok, indeks masa tubuh yang tinggi, dan penyakit-penyakit kronis lain sering memberikan efek pada panjang telomer. Banyak penelitian yang menyatakan Latihan fisik dapat berpotensi untuk menahan proses pemendekkan telomer. Ada berbagai mekanisme molekuler yang terkait dengan permasalahan maupun solusi yang ada dalam latihan fisik tersebut. Pencegahan penyakit metabolik telah banyak dikaitkan dengan latihan fisik. Penuaan sel yang dapat ditahan oleh aktivitas fisik maupun latihan fisik dapat menjadi salah satu jalur yang dapat dipikirkan mengenai mekanisme molekuler tersebut.

Pengagihan Sumber Perubatan Terhad Dalam Menangni Pandemik Covid-19:Prinsip Keadilan dari Perspektif Bioetika dan Sharia'ah
Authors: Alias Fadhlina , Hussin Syaryanti
Published: December 2020

At the end of 2019, the world was shaken by the discovery of a new coronavirus strain (SARS-CoV-2), which was identified to be the source of the outbreak that originated in China. The outbreak, which was subsequently named COVID-19, was declared as a pandemic by the World Health Organisation and has adversely affected and impacted upon many countries, not only from the aspects of medical and health care services, but also with respect to economic stability, financial management and social security. The treatment of COVID-19 patients is costly and involves limited resources, particularly in the case of critically ill patients who require mechanical ventilation. Thus, medical practitioners are faced with complex issues in justifying the distribution of health care resources to deserving patients. This article seeks to discuss the concept of justice in the distribution of health care resources from the bioethical and Islamic standpoints. The research employs the qualitative method of doctrinal analysis, which comprises primary and secondary sources relating to the principle of justice in contemporary medical ethics and from the sharīcah point of view. Findings of this study illustrate that there exist similarities between the two perspectives, which among others, include the agreed nexus between the allocation of scarce resources to patients and deliberations on the futility of medical treatment.

Abstrak

Pada penghujung tahun 2019, dunia digemparkan dengan penemuan strain coronavirus baru (SARS-CoV-2) yang dikenalpasti sebagai punca wabak absah yang bermula di China, yang kemudiannya dinamakan COVID-19. Wabak yang telah diisytiharkan sebagai pandemik oleh Pertubuhan Kesihatan Sedunia ini menjejaskan dan memberi impak yang signifikan terhadap kelangsungan sesebuah negara bukan sahaja dari aspek perkhidmatan perubatan dan penjagaan kesihatan, tetapi juga dari segi kestabilan ekonomi, pengurusan kewangan dan keselamatan sosial. Rawatan pesakit COVID-19 melibatkan kos yang tinggi dan sumber yang terhad, terutamanya pesakit-pesakit kritikal yang memerlukan alat bantuan pernafasan. Oleh itu, pengamal perubatan berhadapan dengan isu-isu yang kompleks tentang kewajaran pengagihan sumber yang terhad kepada pesakit yang berhak. Makalah ini bertujuan untuk mengupas konsep keadilan dalam pengagihan sumber perubatan dari sudut pandangan bioetika dan bagaimana Islam menangani isu tersebut. Kajian ini mengaplikasi metode kualitatif iaitu analisa doktrin yang merujuk kepada sumber-sumber utama dan sekunder berkaitan prinsip keadilan di dalam etika perubatan moden dan dari sudut pandangan sharīcah. Hasil kajian mendapati bahawa terdapat persamaan di antara kedua-dua perspektif tersebut, antaranya justifikasi pengagihan sumber perubatan yang terhad berkait rapat dengan pertimbangan tentang rawatan perubatan yang tidak membawa apa-apa manfaat (futile treatment).
