The number of dentist serving the rural areas is relatively low and the practice of seeking general physiciansfor dental treatments can still be evident in areas where dental services are not accessible. But it is unclearwhether students from suburban regions prefer to pursue dentistry as their first choice of preference. Hence,the present study was aimed to find the interest in dentistry among the aspiring school students, to evaluate ifthe existing exams remain a challenge, from choosing a medical course, and also to assess if the emergenceof COVID-19 has actually increased the popularity of traditional medicines. A survey questionnaire with16 questions was shared through online media to 200 school students both in urban and suburban regionsafter validation for this pilot study. After consent to participate, the responses collected were tabulated andstatistically analyzed. It was observed that only 64% (urban) and 73% (suburban) were aware of dentistrywith a slight increase in student’s choice for traditional medicine courses over allopathic medicine (40%urban, 48% suburban) post pandemic. Within the limitations of this study it is evident that school studentsare less aware of various dentistry courses, and access to training for the exams can motivate the number ofstudents seeking admission to dentistry courses.

Published: April 2021

Infertility is an issue on the rise worldwide. Infertility treatment globally has undergone a gradual revolutionfrom the traditional treatment to the use of assisted reproductive technology (ART). ART is presently themost sought after technology that successfully treats millions of infertile couples over the world. However,the utilization of ART still differs between various nations owing to varying socioeconomic, cultural andreligious reasons. The sudden increase of this technology has introduced numerous social, ethical, and legalchallenges. This paper assesses the awareness level and attitude amongst medical students and interns inChennai regarding some of the most vital and tricky topics in the field of ART and outlines the ethical,legal and social challenges they bring in. This questionnaire-based study involved 427 participants whoencompassed medical students and interns from tertiary care hospital at Chennai. The responses werecollected, tabulated and statistically analysed. About 2/3rd of the participants were females. 94% of therespondents declared that they are aware of ART (401), 63% answered that all the information was obtainedfrom the medical college. Over 2/3rd of the study population was aware of one of the ART methods. 70.8%(302) amongst the participants felt that ART solved all problems of infertility.86.7% of the respondents(370) knew that Spousal agreement to opt for A.R.T is a must. 90.6% (387) of the study population were ofthe opinion that revealing the identity of the sperm donor would cause psychological, social and attitudinalissues among the recipients & the spouse. 29.6% of the participants felt that donation of the surplus embryosfor research purposes was the best option. The gaps in knowledge about newer methods and proceduresregarding ART were identified. Medical students must be agents of socio-medical information and thismakes them good ambassadors for healthy living and fertility awareness. The introduction of governmentrun ART centres and reduction in the cost of the services will go a long way in encouraging more personsto use the services.

Paracelsus, the father of toxicology, once wrote:”Everything is poison, there is poison in everything. Onlythe dose makes a thing not a poison.” A corrosive is a substance which has surface-destructive effect oncontact. Corrosive poisoning results from ingestion, topical exposure or inhalation of compounds, thatcauses tissue injury by chemical reaction. An average home contains a dozen different cleaning products.These products are used in many industries. These are responsible for a large number of accidental andintentional poisoning. This study “A Comprehensive Study Of Deaths from Corrosive Poisoning” is takenup Over 47 corrosive poisoning fatalities autopsied at the Department of Medicine and Department ofForensic Medicine, Osmania General Hospital, Hyderabad to make an attempt to ascertain the frequencyof poisoning fatalities and to suggest suitable remedial measures to reduce the morbidity and mortality dueto corrosive poisoning. Incidence in males (66.91%) is more than in females (33.09%).The most frequentlyinvolved victims belong to the age groups 21 to 30 years, than 11 to 20 years and 31 to 40 years. In majorityof the cases, the poisoning was suicidal (93.62%) and then they were accidental (6.38%).

Published: April 2021

Halitosis is an important social complaint which affects both healthy and periodontally diseased individuals.Oral malodor is mainly caused by a microbial degradation of both sulfur-containing and nonsulfur-containingamino acids into volatile, bad-smelling gases. Anaerobic gram-negative bacteria, the same species that havebeen linked to periodontal diseases, are especially involved in this process, explaining the link between oralmalodor with periodontitis. The following study was done to investigate the parameters of halitosis andsialometry of Emirati diabetic patients in correlation with oral concentration of volatile sulfur compounds(VSC), salivary flow rate before and after non-surgical periodontal treatment (scaling & root planning) forpatients having moderate Generalized and/localized chronic periodontitis.Subjects and Methods: Eighty-one (81) Emirati subjects volunteers were recruited from the dental hospital,with average age 38-49 years. They have been divided into in three groups: Group I (negative control),Group II, and Group III and Group IIIa. Halitosis measurements for all volunteers had been recorded usingGas Chromatography. For group III samples were collected before periodontal treatment, and subsequentlyat two- & four-weeks following start of non-surgical periodontal treatment (Scaling & root planning).Results: There were 54 patients participated in this study. Of the 54, 27 were control and the remainingwere controlled DM. The mean and SD of all variables before and after the intervention showed that thevalues of all variables reducing after the intervention. All the difference observed was statistically significant(P<0.001). This study observed that the mean value of unstimulated salivary flow rate and stimulated salivaryflow rate was less in the controlled DM group compared to control group, but for probing picker depth, CALand average bone loss was more in controlled DM group compared to control group.Conclusion: Based on the findings, it can be stated that diabetes is a major risk factor for periodontitis, andthe risk of periodontal disease increases if glycemic control is poor; it was also proved beyond doubt thatpeople with poorly controlled diabetes are at an increased risk of periodontal disease and loss of alveolarbone. Controlling diabetes by successfully improving glycemic control will reduce the risk and severity ofperiodontal diseases.

Background : Intestinal obstruction is one of the common abdominal emergencies and if not treated anddelayed it may lead to bowel ischemia. Hence diagnosis and management of the patient with intestinalobstruction is one of the most important and challenging step to decrease its morbidity and mortality. Thismortality due to acute intestinal obstruction can be decreased with better understanding of pathophysiology,improvement in diagnostic techniques, fluid and electrolyte correction, much potent antimicrobial hence ourstudy focuses on early diagnosis of obstruction, skill full operative management, proper technique duringsurgery and intensive postoperative treatment and carries grateful results.Aim and Objectives :1. To study the various causes of intestinalobstruction.2. To study the symptomatology of intestinalobstruction.3. To study the various Modalities of treatment(surgical) and also the role of imaging studies in determiningthe etiology and intervention in intestinal obstruction.Conclusion : Through our study we came to the conclusion that men are more commonly involved thanfemales . Plain X-ray abdomen and ultrasonography were important for diagnosing out of which Plain X-rayerect abdomen was almost conclusive in all cases. Where diagnosis was inconclusive an ultrasonographywas carried out. Amongst the causes, Postoperative adhesions are the common cause to produce intestinalobstruction. Intestinal obstruction with tuberculosis intestine are more likely to develop postoperativecomplications, proper anti-tubercular management is necessary to prevent mortality and morbidity. Earlyoperations depending upon the etiology of obstruction are mandatory to avoid perforation, the developmentof peritonitis and systemic sepsis associated with multisystem organ failure. Through our study, Adhesiolysisfollowed by resection and anastomosis were the two procedures which were commonly performed.

Various factors lead to neonatal mortality, in which transport of neonates play an important role in mortalityand morbidity of neonates. In India neonatal transport has not developed well. Many sick neonatessuccumb during transport or become very serious during transport. Transport duration, type of transport,treatment given during transport , if pretransport treatment received, maintenance of hemodynamic stability,maintenance of temperature and blood sugars during transport is essential for reducing the mortality of thebaby. Regionalizing neonatal care, will help in deciding the transport of neonates from one centre to anhigher level of care. Hence a well-organized transport system should be in place for the transport of the sickneonates. This review article discusses about the neonatal transport and its implications.

Background: Rheumatoid arthritis is an immunological mediated, chronic inflammatory multisystem diseasewhich involves inflammation of the peripheral joint. Ra affects about 24.5 million people as of 2015 and theincidence rate is more dominated amongst female. Historically the involvement of the cervical spine in laterstages of rheumatoid arthritis isn’t uncommon. Specifically, C1 and C2 are involved as they are the onlyvertebrae without intervertebral disc and synovial lining and hence they are very susceptible to inflammationdue to autoimmune reaction. The alteration in the range of motion is quite significant at the cervical spine.The biomechanics of the cervical spine and shoulder joint are interlinked with each other. The protocol ofspecific cervical and upper shoulder stabilization exercises with electrical modalities like hot-moist packand transcutaneous electrical nerve stimulation and short wave diathermy therapy was conducted to findout the effectiveness of scheduled, designed physiotherapy protocol of specific stabilization exercises alongwith electrotherapy for cervical spine and upper shoulder stabilization exercises to see the improvement incervical and shoulder range of motion and pain in patients with rheumatoid arthritisMethodology: An observational study was conducted in 25 patients at Karad with a study duration of 6months. The inclusion criteria were the patient with rheumatoid arthritis any age and gender willingly toparticipate. The outcome measures were universal goniometer for assessing cervical and shoulder range ofmotion, the visual analogue scale for pain assessment.Conclusion: The study concluded that there was a significant reduction in the range of motion in both thecervical spine and shoulder joint. The visual analogue scale suggests there was significant pain present inthe shoulder joint and cervical spine. Post-treatment assessment suggests the improvement in the range ofmotion and pain that leads to improvement in the quality of life.

Berlin Antlaşması Osmanlı Devleti açısından son derece olumsuz sonuçlar doğurmuş, adeta devletin yıkılmasına giden sürecin başlangıç noktasını teşkil etmiştir. Rusya'nın bilhassa Balkan politikası nedeniyle mimarı olduğu ve tarihe 93 harbi olarak geçen 1877-78 Osmanlı Rus Savaşı dünya tarihi açısından çok önemli sonuçlar doğurmuş, savaş sonrası büyük devletler Osmanlı Devleti'ne karşı yürüttükleri politikalarında köklü değişikliklere gitmişlerdi. Özellikle İngiltere Osmanlı Devleti'nin toprak bütünlüğünü korumak şeklindeki tarihi politikasını terk etmiş, Rusya'nın savaş sonrasında Osmanlı coğrafyasında avantajlar elde etmesi sebebiyle Ayastefanos Antlaşması'nın Berlin'de tadilini sağlamıştır. Ayastefanos Antlaşması ile Ermeniler iki devlet arasında yapılan bir anlaşma maddesine ilk kez konu olmuşlardır. Berlin'de bir konferans toplanacağı haber alındığında Ermeni Patrikhanesi buraya bir heyet gönderme kararı aldı. Heyet Avrupa başkentlerini dolaşarak kongrede kendilerine destek olunmasını, ilgili devletlerin yetkililerinden talep etti. Patrikhane'nin bu heyetinde cemaatin yakından tanıdığı eski Patrik Mıgırdıç Kırımyan, Minas Çeraz, Stefan Papazyan ve Horen Narbey vardı. Heyet Roma, Paris, Londra'da görüşmeler yaptıktan sonra Berlin'e gitti. Hem Avrupa başkentlerinde ilgili devletlerin dışişleri bakanları gibi önemli kimselerle yaptıkları görüşmelerde hem de Berlin'de kongreye katılan devlet temsilcileri nezdinde ciddi bir kulis faaliyeti, adeta propaganda yapan heyet kongrenin sonuna kadar Berlin'deki faaliyetlerini sürdürdü. Bu çerçevede çalışmada heyetin Avrupa başkentleri ve Berlin'deki faaliyetleri arşiv vesikaları, yerli ve yabancı kaynaklarla ele alınacak, sürecin Ermeni Meselesi'ne nasıl bir etkisi olduğu değerlendirilecektir.
İngiliz Konsolosluk Raporlarına Göre 93 Harbi Sonrası Erzurum Vilayeti’nde Sosyo-İktisadi Hayat (1878-1885)

93 Harbi (1877-1878 Osmanlı-Rus Savaşı) sırasında Osmanlı Devleti'nin bazıtoprakları işgal edilmiş, harp devletin hemen hemen tüm kurum ve kuruluşlarını olumsuz etkilemiştir. Bununla bağlantılı olarak özellikle savaşın cereyan ettiği bölgelerde iktisadi ve sosyal hayat olumsuz etkilenmiş, hatta durma noktasına gelmiştir. 93 Harbi sonrası Erzurum'un sosyo-iktisadi yapısı, Erzurum İngiliz Konsolosluğu görevinde bulunan Harry Charles Augustus Eyres, William Everett ve George Pollard Devey'in yazışmaları ve raporlarında geniş yer bulmuştur. Konsolos Augustus Eyres, Erzurum Vilayeti'nin ekonomik yapısı hakkında yıllardır rapor yazılmadığını ve vilayetin ekonomik yapısının ortaya çıkarılmasının önemli olduğunu belirterek özellikle 1880, 1881 ve 1882 yıllarına dair vilayetin sosyo-iktisadi yapısı ile ilgili ayrıntılı değerlendirmeler yapmış, önemli istatistiki bilgilere yer vermiştir. Konsolos William Everett 1882 ve 1883, Vekil Konsolos George Pollard Devey de, 1884 ve 1885 yıllarına dair vilayetin sosyo-iktisadi yapısına dair ayrıntılı değerlendirmelerde bulunmuşlardır. Her üç konsolos da raporlarında karşılaştırmalı bilgiler sunmuş özellikle savaş sonrası Erzurum Vilayeti'nin iktisadi ve sosyal hayatını kaleme almışlardır. Çalışmada temel kaynak olarak kullanılan İngiliz Konsolosluk belgeleri, Erzurum Vilayeti ve çevresinde bulunan diğer yerleşim yerlerinin ekonomik ve bununla bağlantılı olarak sosyal yapısını ortaya koyacak önemli bilgiler ihtiva etmektedir. Çalışma dâhilinde Erzurum Vilayeti'nin mevcut pazar durumu, yıllık gelirgider kalemleri, Fransa, Avusturya, Amerika, Almanya, İsviçre, İran, İngiltere, Rusya gibi doğulu ve batılı devletlerden ithal edilen ve Erzurum Vilayeti'nden de yabancı ülkelere ihraç edilen, ayrıca Van, Bitlis, Muş, Siirt, Diyarbakır, Mardin, Halep, Harput, Trabzon, Samsun, Rize, Erzincan, Arapkir, Ayntab, Bağdat, Karahisar, Palu ve Tokat'dan alınan ve bu bölgelere satılan ürünlerin miktarı ve piyasa değeri tablolar halinde verilmiş ve bazı emtianın da önemine binaen ayrıntılı değerlendirmeleri yapılmıştır. Çalışmada Erzurum Vilayeti'nin savaştan ne kadar etkilendiğinin yanında dönem itibariyle vilayetin ticaret potansiyeli de gözler önüne serilmeye çalışılmıştır.

Only 18 chicks were born out of 400 pairs, of which 13 flew.
APPLICATION OF AN OPTIMAL CONTROL ALGORITHM FOR A GYROSCOPE SYSTEM OF A HOMING AIR-TO-AIR MISSILE
Authors: Krzysztofik Izabela , Koruba Zbigniew
Published: April 2021

Missile homing precision depends mainly on the correct determination of the current angle between the Gyroscope System Axis (GSA) and the target line-of-sight (LOS). A gyroscope automatic control system shall ensure spontaneous levelling of this angle, hence, constant homing of the gyroscope system axis in on the LOS, i.e. tracking the target by the head. The available literature on the subject lacks a description of how to use the controlled gyro system in the process of guiding the missile onto the target. In this paper, the authors present the original development of an optimal control algorithm for a gyro system with a square quality indicator in conditions of interference and kinematic influence of the missile deck. A comparative analysis of the LQR with the PD regulator was made. PD regulator parameters are also selected optimally, using the Golubencev method, so that the transition process of the homing system fades over a minimal time, while simultaneously ensuring the overlapping of the gyroscope axis with the target line-of-sight. The computer simulation results have been obtained in a Matlab-Simulink environment and are presented in a graphic form.
NET BENEFITS OF URBAN SLUMS REDEVELOPMENT POLICIES ON THE VALUE OF ADJACENT RESIDENTIAL PROPERTY
Authors: Hussain Touseef , Wei Zou
Published: April 2021

Over time, the government of Pakistan introduced several strategies to deal with the issue of slums in its capital city, Islamabad. Contrary to the traditional strategies that primarily focus on the tenure security of occupants, the strategy of slum redevelopment is more composite. It involves the up-gradation of slums in their existing sites as well as the demolition of slums from the posh areas. The present study is first to empirically investigates the outcomes of the slums redevelopment policies on the value of adjacent residential properties. Using a rental valuation based hedonic price model, the study examined the spillover effects of an urban slum up-gradation and eviction projects on the nearby housing values. The results show that the redevelopment of slums reduces the adverse effects on residential value. It is essential for the urban planners to cautiously include the slum redevelopment projects spillover effects on the adjacent property value in different geographical locations, to maximize the net positive effects of improvements on the neighborhood.
A TYPE-2 FUZZY OPTIMIZATION MODEL FOR PROJECT PORTFOLIO SELECTION AND SCHEDULING INCORPORATING PROJECT INTERDEPENDENCY AND SPLITTING
Authors: Zolfaghari Samaneh , Mousavi Seyed Meysam , Antuchevičienė Jurgita
Published: April 2021

This paper presents a new optimization model and a new interval type-2 fuzzy solution approach for project portfolio selection and scheduling (PPSS) problem, in which split of projects and re-execution are allowable. Afterward, the approach is realized as a multi-objective optimization that maximizes total benefits of projects concerning economic concepts by considering the interest rate and time value of money and minimizes the tardiness value and total number of interruptions of chosen projects. Besides, budget and resources limitation, newfound relations are proposed to consider dependency relationships via a synergy among projects to solve PPSS problem hiring interval type-2 fuzzy sets. For validation of the model, numerical instances are provided and solved by a new extended procedure based on fuzzy optimistic and pessimistic viewpoints regarding several situations. In the end, their results are studied. The results show that it is more beneficial when projects are allowed to be split.
Telepharmacy and opportunities for its application in Bulgaria
Authors: Kilova Kristina , Peikova Lily , Mateva Nonka
Published: April 2021

The application of telepharmacy opens new perspectives in the provision of health services and contributes to limiting the problem of reduced availability of pharmacists. The aim of the present study is to examine the attitudes towards offering and using telepharmaceutical services in Bulgaria. The study included 379 people, mostly health professionals. The mean age of respondents was 44.38±12.39. Statistical analyses were performed using IBM SPSS Statistics v.23. Over 90% of the respondents use the Internet to search for health information. Many of them read the package leaflet before use. For the most part, respondents are distrustful of food supplements sold on the Internet. More than 56% claim they would not buy prescription medicines online or via a mobile app, even if it was allowed by law. Quite a few would consult a pharmacist for a therapy prescribed at a distance as well as use a mobile application to monitor drug therapy. The spread and acceptance of telepharmacy is a challenge involving cooperation between the public and private sectors, as well as scientific institutions and academia, which is essential for achieving appropriate results and effectively improving health services.
Jung psychiatre, le Burghölzli et la rencontre avec Freud
Authors: Lovering Catherine
Published: April 2021

Dans la correspondance Freud-Jung, il n’y a ni résumé ni mots-clés. La lecture n’en est pas un chemin balisé, avec pancartes et flèches, ni une visite guidée. Alors, faites un pas, avancez-vous jusqu’à la première lettre et entrez, comme dans la forêt, tous sens aiguisés, entrer dans ses enchevêtrements, ses ombres et jeux de lumière, ses clairières, ses chemins de traverse et sources cachées. Cette lecture est une expérience.
Pater mortalis et puer æternus
Authors: Gaumond Marcel
Published: April 2021

Interrogeant les mobiles qui provoquèrent la rupture du lien personnel intervenue entre S. Freud et C. G. Jung, peu avant le début de la Première Guerre mondiale, l’auteur propose d’éclairer cette rupture sous l’angle du conflit énigmatique ayant émergé dans le rapport entre les deux hommes, un conflit mettant en scène deux figures mythiques, soit celle d’un père qui craint d’être tué par son fils et celle d’un fils dont la survie est sérieusement menacée dès la naissance.
Du dispensaire d’hygiène mentale au centre médico-psychologique enfant : une histoire des intersecteurs de pédopsychiatrie
Authors: Monduit de Caussade Camille
Published: April 2021

Le « centre médico-psychologique » ( cmp ) a une histoire. De nombreuses histoires individuelles racontant la vie de plusieurs générations d’équipes de secteur, mais également une histoire propre. Anciennement nommé dispensaire d’hygiène mentale, la circulaire du 16 mars 1972, acte de naissance de la psychiatrie infanto-juvénile de secteur, le définit comme « l’élément de base du dispositif de secteur », « un centre de diagnostic et de traitement ambulatoire pour enfants ». La période de sa naissance est aussi celle de la refondation de l’institution hospitalière, des controverses liées à la loi sur le handicap et d’un mouvement psychiatrique en plein essor. À l’heure où certains cmp sont fermés, regroupés, fusionnés ou menacés, retracer l’histoire des centres médico-psychologiques, le contexte historique et sociologique, à travers la consultation des archives de différents ministères, prend tout son sens.
