The Performance of Education System in Different Welfare Regimes in School to Work Transitions: Denmark, France, Spain, Greece, and Turkey
Authors: ÇELİK Çetin
Published: July 2020

School systems and their links with the labor market play an important role in students’ success or failure and, consequently, facilitate (or not) their later access to the labor market. This article presents a comparison of the effects of different welfare regimes on school to work transitions. By drawing on an intense desk study and secondary analysis, the article examines five countries with different welfare regime types and reveals how they shape schooling and school to work transitions, particularly for disadvantaged groups. These countries are Denmark (universalistic regime), France (employment- centered regime), Spain, Greece, and Turkey (sub-protective regime). The article also addresses potential policy transfers in the findings.

Published: July 2020

Deniz yolu taşımacılığına olan ilginin artması, deniz kazaları sonucunda
petrol kirliliğinin de artmasına yol açarak, meydana geldiği bölgeyi olumsuz
yönde etkilemektedir. Bu çalışmada üç boyutlu hidrodinamik ve taşınım modeli olan MOHID
kullanılarak petrol kirliliğinin yayılımı incelenmiştir. Çalışma bölgesi olarak
Türkiye için stratejik önemi haiz petrol rafinerilerinin ve dolum
istasyonlarının bulunduğu Doğu Akdeniz bölgesi seçilmi ve gemi trafik akışının
yoğun olduğu Mersin İli önü ve İskenderun Körfezi’nde üç bölge için kaza
senaryoları üretilmiştir. Model validasyonu, Coriolis projesi kapsamında Mart
2014’de Mersin önlerinde denize bırakılan şamandıranın topladığı verilerin,
model verileri ile karşılaştırılması ile yapılmıştır.

Yaz mevsimi simülasyon sonuçları incelendiğinde, kirliliğin kuzeydoğuya,
körfezin içine doğru yayılacağı, İskenderun Körfezi’ndeki iki kaza noktası için
kirliliğin İskenderun ve Dörtyol ilçesi kıyılarını, Mersin bölgesi’ndeki kaza
noktası için ise Kazanlı kıyılarını etkileyeceği beklenmektedir. Kış mevsimi
simülasyon sonuçları incelendiğinde ise, petrol kirliliğinin güneybatıya,
körfez ağzına doğru ilerleyeceği, İskenderun Körfezi’nde uzunca bir sahil
şeridinin kirliliğe maruz kalacağı, Mersin bölgesinde de kirliliğin kıyıya
paralel olarak hareket edeceği ve 4 gün sonunda Erdemli Bölgesi’ne varacağı beklenmektedir.
Yayılımın hızına da bakıldığında, bu sonuçlar, hem yaz hem de kış mevsiminde
önceden modelleme ile petrol kirliliğinin yayılımının tahmin edilmesi
sayesinde, acil durumlarda hızla müdahale edilerek bariyer kullanılmasının
petrol kirliliğinin geniş bölgelere yayılmasını engelleyebileceğini
göstermektedir.

Published: July 2020

Güç
transformatörleri, enerji iletim ve dağıtım sistemlerinin en vazgeçilmez
bileşenlerinden biridir. Güç elektroniği ve mikroişlemci teknolojisindeki
gelişmelerle birlikte, yakın bir gelecekte klasik güç transformatörlerinin
yerini alması beklenen Elektronik Güç transformatörleri (EGT’ler)
geliştirilmekte ve tasarlanmaktadır. EGT’ler uygun tasarımlarla klasik güç transformatörlere
göre daha az hacim ve ağırlığa sahip olmaktadır. Ayrıca, uygun EGT yapısı ile reaktif
güç kompanzasyonu, harmonik kompanzasyon, gerilim çökmesi/yükselmesi kompanzasyonu
gerçekleştirebilmektedir. Bu çalışmasında, giriş, izolasyon ve çıkış
kısımlarından oluşan üç-fazlı bir EGT’nin deneysel kurulumu
gerçekleştirilmiştir. Bu EGT yapısı
ile şebekedeki bozucular, giriş kısmında bulunan DA-baralar sayesinde kompanze
edebilmektedir. Genellikle, EGT’nin giriş kısmında Darbe Genişlik Modülasyonu
(DGM) tabanlı doğrultucular yaygın olarak kullanılmaktadır. DGM tabanlı
doğrultucuların denetiminde ise basit yapılarından dolayı PI ya da PID
denetleyiciler tercih edilmektedir. Fakat bu denetleyiciler sabit kazanç
parametrelerine sahip oldukları için doğrusal olmayan sistemlerde tatmin edici
performans gösteremezler. Bu nedenle, bu çalışmada giriş kısmındaki DA-bara ve
dq-eksen akımlarının denetimi için Tip-2 Sinirsel Bulanık Denetleyici (T2SBD)
önerilmiştir. Ayrıca, önerilen denetleyici yapısı ile EGT’nin bozuculara karşı
performansının iyileştirilmesi amaçlanmıştır. EGT’nin giriş ve çıkış kısımları
için geliştirilen denetim algoritmaları dSPACE DS1104 denetleyici kartı ile
sağlanmıştır. T2SBD ile denetlenen
EGT’nin gerilim çökmesi, yükselmesi, harmonik ve reaktif güç kompanzasyonu
performansını göstermek için gerçek zamanlı çalışma durumları hazırlanmış ve
deneysel sonuçlar elde edilmiştir.

Tam otomatik otopark sistemlerinde operasyonel planlama ve kontrol problemleri üzerine bir inceleme
Authors: DUDAKLI Nurhan , BAYKASOĞLU Adil
Published: July 2020

Şehirlerde hızla artan nüfusun yanında çeşitli ekonomik ve sosyal gelişmeler, araç sayısında ciddi bir artışa neden olmuş ve bu durum, şehirlerde park yeri sorununu önemli bir gündem haline getirmiştir. Özellikle kalabalık şehirlerdeki sınırlı boş alanlar göz önüne alındığında, geniş alanlara ihtiyaç duyan geleneksel otoparklar (açık alan otoparkları, katlı otoparklar vb.) ihtiyacı karşılama konusunda çoğu zaman yetersiz kalmaktadır. Bu sebeple, teknolojik gelişmelerin de yardımıyla hem yatay hem de dikey alanın daha etkin kullanılmasını sağlayan çeşitli otopark sistemleri geliştirilmiştir. Özellikle son yirmi yılda, sensör teknolojisinin kullanıldığı ve park işlemlerinin otomatik taşıyıcılarla (asansör, konveyör, robot vb.) gerçekleştirildiği Tam Otomatik Otopark Sistemleri (TOOS) yeni nesil otopark sistemleri olarak karşımıza çıkmaktadır. TOOS’ler, tasarımları ve kullandıkları teknolojiler sayesinde park yeri sorununa etkili ve çevre dostu bir çözüm sunmaktadır. Bununla birlikte sistemin etkinliğini/verimliliğini operasyonel anlamda ele alan akademik çalışmalara hala ihtiyaç duyulmaktadır. Nitekim konuyla ilgili literatür incelendiğinde, TOOS'lerin tasarımı ve TOOS’lerde kullanılacak teknolojilerle ilgili çok sayıda çalışma olmasına rağmen, TOOS'lerin operasyonel planlama ve kontrol problemlerini konu alan çalışmaların az sayıda olduğu görülmektedir. Mevcut araştırma kapsamında çeşitli TOOS’ler teknik ve operasyonel açıdan incelenmiş ve operasyonel etkinliği/verimliliği arttıracak potansiyel araştırma/çalışma alanları ortaya konulmuştur.
Elektrik akımı ile yabancı ot kontrolü yönteminde tekli ve çoklu elektrotların mortalite oranı üzerindeki etkisinin NDVI tekniği ile araştırılması
Authors: ŞAHİN Hasan
Published: July 2020

Bu çalışmada, yabancı ot mücadelesinde yaygın olarak kullanılan kimyasallar yerine, çevreci bir yöntem olan elektrik akımı yönteminde farklı elektrot tiplerinin mortalite oranı üzerindeki etkisi araştırılmıştır. Bu amaçla geliştirilen tekli ve çoklu elektrot düzeneğinde, laboratuvar ortamında çimlendirilen bitkilere 100 saniye sürelerle 110, 220 ve 300 volt AC gerilim uygulanmıştır. Bitkiler üzerinden geçen elektrik akımı, uygulanan gerilim ve gerçekleşen mortalite oranları arasındaki ilişki incelenmiştir. Tekli ve çoklu elektrot uygulamalarının her ikisinde de 110 volt 100 s tekerrürlerinde bitkilerin 1 hafta sonunda ölçülen NDVI değerlerinde bir artış olduğu gözlenmiştir. Başka bir ifadeyle, uygulanan düşük gerilimlerin bitkilerin çimlenme oranlarında bir artışa neden olduğu tespit edilmiştir. Buna karşın, 220 ve 300 volt gerilimlerde ise tekli elektrot yönteminde %8 ile % 11 arasında mortalite oranları gerçekleşmiştir. Çoklu elektrot yönteminde ise bu oranlar %10 ile % 17 civarlarında gerçekleşmiştir. Ayrıca, “uygulanan gerilim” ile “elektrot yöntemi” arasında istatistik olarak anlamlı bir farklılık gözlenmiştir (p<0,05). Buna göre; hem “çoklu” hem de “tekli elektrot yönteminde” “mortalite” ile “elektrik akımı” arasında istatistik olarak anlamlı pozitif bir korelasyon gözlenmiştir (p<0,05). Bu ilişkilerin derecesi (r) ise yaklaşık %89’dur. Bu sonuçlara göre, elektrik akımı arttıkça mortalite oranları da artmaktadır.
Optical properties of PEDOT:PSS-silicon solar cells
Authors: Mykytiuk A. , Kondratenko S.
Published: July 2020

We study the optical and electrical losses in PEDOT:PSS/n-Si solar cells using spectroscopic ellipsometry and current-voltage measurements. The optical constants and thickness of the PEDOT:PSS films were studied using spectroscopic ellipsometry performed by a SE-2000 SEMILAB ellipsometer spanning the NIR–VIS–UV range with a resolution of 5 nm. The results were analyzed using a four-layer model involving the ntype silicon (001) substrate, interfacial layer between Si and polymer films, PEDOT:PSS thin film, and a surface roughness layer. The key to understand the origin of the losses is that the studied junctions have an interfacial layer between organic (PEDOT:PSS) and inorganic substrates. The dielectric functions of the PEDOT:PSS were fitted with the known thickness and the assumption of a negligible roughness (i.e. that the roughness is much smaller than the wavelength). Using the complex dielectric function, the optical constants (refractive index n and extinction coefficient k) were calculated. In addition to real and imaginary part of the refractive index, the absorption coefficient was calculated. The produced hybrid solar cells show efficiencies around 7%.
Mathematical modelling of particle aggregation and sedimentation in the inclined tubes
Authors: Baranets V. , Kizilova N.
Published: July 2020

Sedimentation of the aggregating particles in the gravity field is widely used as an easy and cheap test of the suspension stability of different technical suspensions, blood and nanofluids. It was established the tube inclination makes the test much faster that is known as the Boycott effect. The dependence of the sedimentation rate on the angle of inclination is complex and poorly understood yet. In this paper the two phase model of the aggregating particles is generalized to the inclined tubes. The problem is formulated in the two-dimensional case that corresponds to the narrow rectangle vessels or gaps of the viscosimeters of the cone-cone type. In the suggestion of small angles of inclination the equations are averaged over the transverse coordinate and the obtained hyperbolic system of equations is solved by the method of characteristics. Numerical computations revealed the increase in the initial concentration of the particles, their aggregation rate, external uniform force and inclination angle accelerate the sedimentation while any increase in the fluid viscosity decelerates it that is physically relevant. Anyway, the behaviors of the acceleration are different. Based on the results, a novel method of estimation of the suspension stability is proposed.

The article describes combatants’ and children’s personal traits changed as a result of their psychological trauma. The research includes a comparative psycho-diagnostic study of the combatants from the National Guard of Ukraine and children from the anti-terrorist operation area living now at the International Children’s Center «Artek» (Kyiv, Puscha-Voditsa). Differences in indicators of post-traumatic stress disorder of the combatants and the children have been revealed. Based on the correlation analysis, the age differences for the main psychological factors influencing vulnerability to destructive post-traumatic stress disorder have been determined. These personal determinants of the combatants and the children, who are victims of combat operations, help us to reveal the specifics of psychological prophylaxis taking into account age-related characteristics. The article shows there are a number of personal traits that require correction regardless of victims’ age-specific characteristics during psychological assistance and psychological rehabilitation. In addition, the article identifies the differences in personal characteristics of the affected combatants and children that should be taken into account at application of psycho-corrective measures based on clients’ age-related features.
CREОLIZED TEXTS (COMICS) AS A TOOL FOR ACTIVATION OF YOUTH’S NATIONAL AND CIVIC
SELF-IDENTIFICATION
Authors: Sosniuk O. , Оstapenko I.
Published: July 2020

The article is devoted to the problem of activation of national and civic identity. The authors determined the indicators of national and civic identity for qualitative content analysis of verbal and non-verbal components of multimodal texts (comics). The authors considered the peculiarities of usage of comics in training practice for: actualization of national and civic self-identification barriers of youth in different subsystems of social interaction; increasing the youth’s resistance to propaganda’s influence; fixation of positive change during the training. The authors established, that comics creation as a method has high diagnostic and developmental potential for activation of youth’s national and civic self-identification processes. It was shown, that usage of comics: 1) facilitates the interaction between verbal and non-verbal components of the comics and also has ample opportunities of its usage as a projective technique; 2) provides the procedure’s relevance for the target audience, since creative tasks, that involve comics creation are familiar to youth; 3) matches the basic ways of communication practices change (articulation, reconfiguration, borrowing); 4) enables the realization of clarification, prognostic modeling and construction (reconstruction) of the identification discourse. The authors revealed three basic intentions, that arised among the training participants during the comics’ remake: increase of the comics’ characters activity in defending their own national and civic identity, increase of characters’ assertiveness level (the ability to defend their own standpoint without the violation of anther individual’s moral rights) and willing to search for ways to constructively solve conflict situations. The existence of those intentions can be considered as evidence of participants’ positive change and general effectiveness of the training.
PSYCHOLOGICAL COMPETENCE IN THE STRUCTURE OF PERSONALITY OF A MILITARY PSYCHOLOGIST
Authors: Barinova L.
Published: July 2020

The article analyzes of the results of an empirical research on psychological competence of military psychologists. The current state of military psychology requires innovative approaches to studies of personalities of not only military personnel, but also military psychologists, who perform an important social and professional function. The article shows that psychological competence plays an important role in professional development and practical work effectiveness of military psychologists counselling military personnel in various situations of combat and service task execution. A psychologically competent military psychologist, due to his/her personal and professional skills, is able to reduce risks to be caught up in a trouble situation for him/herself and his/her service members, and if such a situation arises, to propose intensive actions to overcome them. The author’s definition of a military psychologist’s psychological competence, considered as a personality trait, is: this competence is a holistic construct characterizing an individual’s ability to minimize problem situation severity and frequency of their occurrence for this individual and to maximize active actions aimed at life organization and such situation overcoming. The operationalization of the desired construct have lead the author to the conclusion that a military psychologist’s psychological competence is a complex personal trait consisting of four components: psychological competence in the family relations, in professional work, in the material and social area, and in the area of values. As for formal-dynamic qualities, speed and agility of a military psychologist’s nervous system serve as the basis for psychological competence formation; and on the contrary, high emotionality acts as a negative precondition for this construct development. The performed research has shown that psychological competence as a factor of military psychologist’s professional formation promotes formation of attitudes, empathy and a see through capability of empathy, but somewhat reduces the empathy role an as emotional channel.
SUBJECTIVE SLEEP QUALITY AND INTEROCEPTIVE SENSITIVITY CADETS
Authors: Denisiievska A.
Published: July 2020

The article presents the research of the problem of sleep quality of students. After the theoretical analysis of the problem of healthy sleep among cadets and students it was defined that these categories of population are one of the most sensitive to sleep problems, because of changing their social status, increasing responsibility, requirements and tense schedule. This problem is also relevant because of the current military-political situation. The article presents the results of empirical research, which shows the difference between the components of sleep quality among cadets and students. It has been found that there are significant differences between cadets and students by such components as «subjective sleep quality», «sleep latency», «sleep duration», «use of sleeping medication», «daytime dysfunction», which show higher results at cadets. There are no significant differences between cadets and students according to the calculated index of interoceptive sensitivity. Average rates for cadets and students are close to high. Also, there was revealed connection between interoceptive sensitivity and subjective quality of sleep, which is defined by a weak negative correlation between these two indicators. In addition, there also were found a strong positive correlation between sleep duration and interoceptive sensitivity and a weak negative correlation between sleep disturbance and interoceptive sensitivity. The received results open up the opportunities to further research such as: a more detailed and volume study of sleep quality, an intensification of the study of connection between interoception, indicators of sleep quality and subjective sleep quality on different samples.
Complex Shear-Wave Anisotropy from Induced Earthquakes in West Texas
Authors: Robinson Regan , Li Aibing , Savvaidis Alexandros , Hu Hongru
Published: July 2020

We have analyzed shear-wave splitting (SWS) data from local earthquakes in the Permian basin in west Texas to understand crustal stress change and induced seismicity. Two SWS parameters, the fast polarization direction and the delay time, are computed using a semiautomatic algorithm. Most measurements are determined in the Delaware basin and the Snyder area. In both regions, SWS fast directions are mostly consistent with local SHmax at stations that are relatively far from the earthquake clusters. Varying fast directions at one station are related to different ray paths and are probably caused by heterogeneity. In the Snyder area, most northeast–southwest fast directions are from the events in the northern part of the cluster, whereas the northwest–southeast fast directions are mostly from the southern part. The northeast–southwest and northwest–southeast fast directions could be attributed to the northeast-trending normal faults and the northwest-trending strike-slip faults, respectively. SWS results in the Delaware basin have two unique features. First, most shallow earthquakes less than 4 km deep produce relatively large delay times. This observation implies that the upper crust of the Delaware basin is highly fractured, as indicated by the increasing number of induced earthquakes. Second, diverse fast directions are observed at the stations in the high-seismicity region, likely caused by the presence of multiple sets of cracks with different orientations. This situation is possible in the crust with high pore pressure, which is expected in the Delaware basin due to extensive wastewater injection and hydraulic fracturing. We propose that the diversity of SWS fast directions could be a typical phenomenon in regions with a high rate of induced seismicity.
Around the Corner, Across the Globe
Authors: Nickitas Donna M , Pontes Nancy MH
Published: July 2020

Nursing educators wrestle with preparing the future nursing workforce to meet the needs of underserved, vulnerable populations in marginalized communities who suffer significant health disparities and social injustices. This article illustrates the integration of engaged civic learning (ECL) within a social justice framework that prepares baccalaureate nurses as global citizens to provide culturally congruent health care around the corner in local communities and learning abroad programs across the globe.
Multiple partnerships with local organizations were strengthened, with ECL integrated across the nursing curriculum and aligned with local needs of community housing, schools, churches, shelters, and fitness centers. The nursing faculty collaborated with language professors to develop a Spanish for Health Professions program to increase communication between students and the high percentage of Spanish-speaking populations served locally and globally.
A mixed-methods design evaluated program outcomes using descriptive data, student reflections, and the Global Perspective Inventory (GPI) to assess students’ experiences and global learning related to learning abroad during their college experience. Results from pre-surveys to post-survey results showed significant improvement (p < .05) in global learning in 16 of 35 question items. As students journey from entrance into nursing school until graduation, ECL develops them into engaged global citizens.

Results: Among 247 patients, male to female ratio was 2:1 with overall mean age of 42.8±12.6 years. Total bilirubin decreased from baseline to week-4 in treatment with Prunus mume extract and choline (p=0.04). Median and IQR of alanine transaminase levels also reduced substantially from 99 (52) to 42 (36.5) I/U. Aspartate aminotransferase levels significantly decreased from 78.5 (57) to 40 (29) I/U. Overall at the end of treatment on week-4, 26 (10.5%) patients experienced gastrointestinal distress, 25 (10.1%) anorexia, 14 (5.7%) excessive salivation and 29 (11.7%) patients experienced excessive sweating.

Conclusions: This study reported significant improvement in alanine transaminase and aspartate aminotransferase levels after treatment with Prunus mume extract and choline (revolic). It is safe and effective to use them for deranged liver functions tests.
Future of risk based monitoring in clinical trials
Authors: Vyas Niraj R.
Published: July 2020

Drug development is a complex and resource intensive endeavor. The average cost of developing a new drug, has been estimated to be $2 to $3 billion. However, the success rate of clinical trials is very low around and is estimated to be between 3-5%. The common reasons for failure of clinical trials include failure to demonstrate efficacy or safety, budgeting and financing, failure of subjects meeting protocol eligibility criteria, poor investigator site selection, patient withdrawals and dropouts. Considering the growing demands to get better and affordable treatment options, there needs to be fundamental shift required in drug development and specifically the clinical trials oversight processes to mitigate risks and reduce failures. The International Council for Harmonisation in the E6 R2 addendumhas now provided guidelines for adaptation of risk based approach to trial conduct and monitoring to implement mitigation strategies for potential risks which might derail the conduct of the trail. The industry is steadily gearing up to put together the required processes, systems and teams to align to the new ways of working. However with the changing landscape of drug development which includes novel therapies like gene therapy, remote/decentralized trials, growing use of wearable technologies, esource, electronic health record/electronic medical records interoperability, implementation of artificial intelligence and machine learning algorithms, the future of risk based approach towards managing clinical trials is going to be very different from what we see now. This paper explores the impact of these new developments on the future of risk based monitoring in clinical trials.

Background: This study assessed the attitudes toward breastfeeding among mothers receiving healthcare services in Primary Healthcare Centers (PHCCs) in Buraydah, Saudi Arabia. It also examined the association between the mothers’ demographic characteristics and breastfeeding attitudes.Methods: This study utilized a descriptive cross-sectional design. A purposive sample of 415 breastfeeding mothers who were receiving healthcare services from the selected PHCCs during the conduct of the study were recruited in PHCCs in Buraydah, Saudi Arabia. A two-part self-administered questionnaire containing a demographic sheet and the Iowa Infant Feeding Attitude Scale (IIFAS) Arabic version was employed to collect data from the respondents. Descriptive and inferential statistics were used accordingly in data analyses.Results: The overall mean score of the women in the IIFAS was 60.50 (SD = 11.08), with individual scores ranging from 17.00 to 82.00. This finding implies good attitudes toward breastfeeding. Mothers who were divorced/widowed (M = 63.75, SD = 5.20) had significantly better breastfeeding attitudes than married mothers (M = 60.24, SD = 11.38). Mothers who were not working (M = 61.41, SD = 10.03) reported more positive breastfeeding attitudes compared with working mothers (M = 58.36, SD = 13.02).Conclusions: The mothers reported good attitudes toward breastfeeding, but expressed poor beliefs in some areas of breastfeeding. The present findings have implication to medicine, nursing, and healthcare policies.

Background: Obstetric ultrasound forms an essential part of antenatal care around the world. The ultrasound is now widely available and accessible in most government and private health facilities in developing countries. Aim of this study was to determine the reasons for pregnant women’s self-referral and perspectives on the use of obstetric ultrasound.Methods: This was a questionnaire-based cross-sectional study conducted among 198 consenting pregnant women attending prenatal care at Alex Ekwueme Federal University Teaching Hospital, Abakaliki, Nigeria.Results: Of 198 participants, 182 (91.9%) reported performing obstetric ultrasound examination without doctor’s request. Determination of fetal viability (40.7%) was the commonest reason for self-referral to ultrasound examination. Other common reasons include vaginal bleeding (15.3%), estimation of gestational age (9.3%), fetal sex determination (7.7%) and estimation of date of delivery (7.6%). Over half (57.7%) of the participants reported that the prenatal ultrasonography was costly whereas 76.9% believed that ultrasound use was unsafe in pregnancy.Conclusions: The study participants were highly aware of the import of ultrasonography in pregnancy confirmation, dating and fetal wellbeing. As a result, are always willing to carryout prenatal ultrasound even without doctors’ request.

Published: July 2020

Background: Elevated levels of serum uric acid are associated with increased cardiovascular morbidity and mortality. However, this association with cardiovascular diseases is still unclear, and perhaps controversial. The objective of study was to assess the serum uric acid level in patients with Acute Myocardial Infarction (AMI).Methods: Sixty patients with AMI were studied in Department of Medicine/ Department of Cardiology, J.A. Group of Hospitals between 2016 -2018.Details of age, sex, smoking, alcohol consumption and history of ischemic heart disease (IHD) was obtained and recorded. Serum uric acid level was estimated and compared with control group (healthy subjects).Results: Serum uric acid level was significantly higher among AMI patients (6.43±2.60) as compared to control group (4.05±0.95) (p<0.001). Majority (46.7%) of the AMI patients had uric acid level of >7.1 followed by 20% patients who had uric acid level between 4.5-5.9 (p<0.001). Uric acid level was comparable between smoker and non-smokers (p=0.803), alcoholic and non-alcoholic (p=0.086), hypertensive and non-hypertensive (p=0.668), patients with and without diabetes (p=0.278) and patients with a history of IHD and without history of IHD (p=0.403).Conclusions: Serum uric acid may be useful for prognostication among those with pre-existing AMI.

Authors: Bhalshankar Nagesh A. , Ugle Suresh S.
Published: July 2020

Background: Bidi industries workers handle tobacco ingredients during rolling of bidi and inhale tobacco dust and volatile component are present in the work environment. Tobacco absorbed by the body in tremendous amount leading to preventable cause of disease, disability and including chronic obstructive pulmonary disease, cardiovascular, carcinomas, premature death exposure among bidi workers. The goal of this study was to occupational exposure of tobacco dust on status of total thiol level in bidi workers.Methods: Healthy controls - 30 subjects and 90 bidi workers were further subdivided on the basis of work experience in years as, Group-I: 5-9 years (30 subjects), Group-II: 10-14 years (30 subjects), Group-III: 15-19 years (30 subjects). Authors are measure total thiol concentration and thiobarbituric acid reactive substances. All the biochemical parameters measured in study group subjects were statistically compared with those estimated in controls.Results: Highly significant decrease in levels of total thiol was found in all groups of bidi workers as compared to healthy controls (p<0.001) and serum thiobarbituric acid reactive substances levels were significantly elevated in all groups of bidi workers when compared with healthy controls (p<0.001). The study groups indicates that decline the total thiol gradually progresses with increase in exposure period to tobacco dust.Conclusions: The study groups showed that decrease the total thiol level and increases the thiobarbituric acid reactive substances in all groups of bidi workers compared with healthy controls.

Background: Metabolic syndrome is described by the clustering of several risk factors for cardiovascular disease such as hypertension, dyslipidemia, obesity, Insulin resistance, and high fasting plasma glucose. Objective of this study was to determine the frequency and evaluate the components of metabolic syndrome in post-menopausal women.Methods: This Descriptive study was conducted in OPD as well as IPD of Department of Medicine, Sri Siddhartha Medical college Hospital and Research Centre, Tumkur After obtaining written informed consent. Period of study was 24 months.  Purposive sampling was used.Results: Mean age of post-menopausal women was 54.19±8.454 years. Mean age of menopause was 45.41±2.428.  Majority of patients between were between 45-50 years (33.7%). There were high number of women (34.6%) whose postmenopausal duration ranged between 6-10 years. In our study 10(9.6%) postmenopausal women had type 2 DM and 15(14.4%) postmenopausal women had HTN. Metabolic syndrome was present in 65(62.5%) postmenopausal women and absent in 39(37.5%) postmenopausal women. Waist circumference >80 cm (68.3) was the most prevalent component of metabolic syndrome followed by HDL <50 mg/dl (53.8%), BP>130/80 mmHg (51%) triglycerides >150 mg/dl (44.2%)/ and FBS>100 mg/dl (39.4%). There was statistical significance observed between the components of metabolic syndrome and metabolic syndrome in postmenopausal women.Conclusions: The prevalence of metabolic syndrome was high in our study. The components of metabolic syndrome such as waist circumference, FBS, blood pressure, triglycerides were significantly raised and HDL levels were significantly reduced in post-menopausal women with metabolic syndrome.

Published: July 2020

Background: The revision myringoplasty surgery is done for the graft failure after myringoplasty. The surgeons’ make use of the temporalis fascia or cartilage as the graft material. Some surgeons opt for the revision myringoplasty with cortical mastoidectomy as well.

Methods: This study is a retrospective, observational study done in the Department of ENT and Head and Neck Surgery, Tribhuvan University Teaching Hospital from December 2015 to 2019. Data of all the patients undergoing revision myringoplasty with or without cortical mastoidectomy were collected from the record section and included in the study. Post-operatively, the patients were assessed for graft uptake and hearing assessment after six weeks of surgery. Total uptake of the graft was taken as the successful graft uptake. The hearing was assessed by air conduction threshold (AC threshold) and air-bone gap status postoperatively.  

Results: Total of 42 patients were analysed with the graft uptake of 86%. There was no significant difference in the graft uptake on using the temporalis fascia or tragal cartilage. Regarding the hearing assessment, the average pre-operative and post-operative AC threshold was 37.95±5.68 dB and 29.36±6.28 dB. The average pre and postoperative AB gap was 29.97±8.16 dB and 21.85±6.68 dB. The improvement in the hearing threshold was significant (p value <0.05).

Conclusions: The graft uptake rate for revision surgery in our centre was comparable to other studies in the literature. There was significant hearing improvement pre and postoperatively after revision myringoplasty.
Epistemología, salud y género: diálogos entre la cardiología y las ciencias sociales
Authors: Moutran-Barroso Habib Georges
Published: July 2020

La discusión y distinción entre las categorías sexo y género en las investigaciones médicas se ha consolidado como un aporte significado desde las teorías feministas y la filosofía de las ciencias. No obstante, la distinción entre las categorías de sexo y género, en la estructuración del conocimiento médico, no fue identificada sino hasta la década del 70’. A pesar de este hallazgo, continúa siendo prevalente el diseño de investigaciones médicas que no contemplan tales diferencias, por lo que se hace un uso indistinto entre ambas categorías y se genera un conocimiento a partir de este error categorial. Varias investigadoras en el área de la salud y la filosofía de las ciencias han elaborado marcos de referencia para la identificación de dichos errores, al igual que sus consecuencias en las políticas de la salud pública, especialmente en enfermedades como el infarto agudo de miocardio. Por lo tanto, a partir de un análisis interseccional entre las ciencias de la salud y la filosofía de las ciencias, se expondrá en este texto algunas reflexiones acerca de esta problemática.
