A crítica ao utilitarismo em O Liberalismo Político (1993) de John Rawls
Authors: Fabian Eloi Pedro
Published: February 2021

A postura de Rawls na obra de 1993 – não obstante a rápida referência que apresenta às teorias sistemáticas do Utilitarismo de Bentham, Sidgwick, Edgeworth, enquanto teorias razoáveis e abrangentes – é em relação a Mill e seu conceito de individualidade que ele dedica a maior parte da crítica ao Utilitarismo. Uma crítica caracterizada por demostrar as dificuldades de uma doutrina abrangente, fundada numa perspectiva moral, não politicamente legitimada e que não confere um caráter público para as bases da justiça. O Utilitarismo desconsidera a pluralidade de costumes, crenças, concepções de mundo, das sociedades contemporâneas e não percebe a relevância e a necessidade de princípios de justiça formulados publicamente pelos cidadãos livres e iguais envolvidos, através de um neocontratualismo operado pelo véu da ignorância (veil of ingnorance) na posição original. A crítica ao utilitarismo, portanto, gravita mais em torno deste aspecto mais específico e restrito em O Liberalismo Político se comparado com a obra de 1971. A teoria da justiça como equidade por meio do equilíbrio reflexivo, o consenso sobreposto e a nova perspectiva de democracia constitucional é amplamente apresentada como uma alternativa viável e adequadamente fundamentada frente ao Utilitarismo. É o que se pretende explicitar neste artigo.
A sociedade aberta e sua proveniência grega, segundo a perspectiva de Popper
Authors: Vieira Daniel Mota
Published: February 2021

De acordo com a visão de Karl Popper (1902-1994), quando a nova fé que dava sustentação ao humanitarismo começara a se firmar na Grécia, eclodiu a tensão da civilização. Tal reação era acompanhada de fatores como o apelo à tradição, a defesa de velhas virtudes e da velha religião. Desdobrando a visão popperiana, mostramos como esse contexto influenciou a interpretação da política imperialista ateniense por parte do historiador Tucídides. Tomada como oficial, a interpretação tucidideana carrega as marcas da reação contrária ao movimento que rompeu com o tribalismo e instaurou a Sociedade Aberta, cuja marca está na inauguração de uma nova tradição; onde a fé mágica se dissolve e cede espaço à de desafiar teorias e mitos e discuti-los criticamente. Além disso, vê-se a abertura para a liberdade enquanto dimensão do acessível. Assim, partindo da análise feita por Rémi Brague da Oração Fúnebre, de Péricles, discorremos acerca da necessidade da coragem para a liberdade. Tendo em vista vivermos inseridos em uma dimensão ontológica contingente, desdobramos também como a importância de uma boa deliberação do curso das ações é importante para os cidadãos imersos no campo da responsabilidade pessoal considerando a noção aristotélica de virtude moral.

Authors: Huang Jijie , Li Weiwei , Yang Hao , MacManus-Driscoll Judith L.
Published: February 2021

Self-assembled nanocomposite thin films couple two materials into a single film, typically, in the form of vertically aligned nanopillars embedded in a matrix film. High-density vertical heterointerfaces provide a great platform for engineering new physical properties and novel multifunctionalities, as well as for nanoscale device integration. Tremendous research efforts have been devoted to developing different nanocomposite systems. In this article, we summarize recent progress on vertically aligned nanocomposite thin films for enhanced functionalities such as ferroelectricity, tunable magnetoresistance, multiferroicity, dielectricity, magnetic anisotropy, perpendicular exchange bias, novel electrical/ionic properties, interfacial conduction, and resistive switching. Using specific examples, we discuss how and why the fundamental physical properties can be significantly tuned/improved in vertically aligned nanocomposites. Finally, we propose future research directions to achieve further enhanced performance as well as practical devices.

Published: February 2021

Allergic dermatoses have a special place in the structure of allergic diseases in children due to their weight. The most common allergic skin lesions: simple and allergic contact dermatitis, atopic dermatitis, various forms of eczema, acute and chronic allergic urticaria, Quincke's edema, multiforme exudative erythema (Stevens—Johnson syndrome), acute epidermal necrolysis (Lyell's syndrome), toxicodermias, as well as less common dermatoses, in the pathogenesis of which are leading allergic reactions. Despite a number of research research, the difficulties in the determining of the therapeutic approach of allergic dermatoses in children are still observed. According to the international program documents EAACI (European Academy of Allergy and Clinical Immunology), AAAAI (American Academy of Allergy, Asthma & Immunology), PRACТALL (Practical Allergology Consensus Report) in treatment of allergic dermatoses the leading place takes external therapy, which requires an individual approach and daily care of skin. External therapy consists of local application of emollients, topical glucocorticosteroids, topical calcineurin inhibitors, topical antihistamines, keratolytic, keratoplastic, reparants, epithelializing and anti-inflammatory medications, in the case of complicated clinical course of the disease — antibacterial, antifungal, antiviral medications, also with skin care. Purpose — to increase information on modern possibilities of external therapy of allergic dermatoses in children. External pharmacotherapy of allergic dermatoses should be etiopathogenetic and should affect on the mechanisms of allergic inflammation in the skin, elimination of itching, dryness,so finding ways to improve it will help to control the clinical course of the disease, to reduce disability, will promote to improve the life quality in patients.

Acrocephalosyndactyly (ACS) is a group of multiple malformations, the main clinical manifestations of which are acrocephaly and syndactyly. The most common forms are Apert (type I), Pfeiffer (type V), Setra–Hotzen (type II) syndromes. Apert syndrome is the most explored and common form of all types of ACS and Apert syndrome is estimated to occur in 1 in: 100 000 newborns. The syndrome is inherited in an autosomal dominant manner. If the gene is carried by one of the parents, the risk of having a child with Apert syndrome is 50%. The syndrome genome (FGFR2) is located on the long arm of chromosome 10 at locus 10q26. Apert syndrome occurs due to mutations at this locus, but the children karyotype is not changed. The pathognomonic clinical signs of Apert syndrome are craniofacial dysostosis and symmetrical syndactyly of the hands and feet. Acrocephaly («tower skull») — is a consequence of early synostosis of some sutures of the skull. Orbital hypertelorism and exophthalmos are referred to typical facial changes. Among other abnormalities there are heart and vascular defects (25%), cleft palate, malformations of the gastrointestinal tract and kidneys. The diagnosis is made on the basis of clinical symptoms. No treatment has been developed. Life expectancy is short. Purpose — to present a clinical case of a newborn with Apert syndrome. Clinical case. Apert syndrome was suspected prenatally, confirmed after birth. The newborn girl had the characteristic signs of the above-described pathology: «tower head», hypertelorism, saddle bridge of the nose, closed large fontanelle, phalanges of the first finger were wide, the proximal phalanx was triangular, complete cutaneous syndactyly of the II–IV fingers was observed symmetrical on both upper extremities; on the lower extremities — thickening of the proximal phalanges of the big toes, complete cutaneous syndactyly of the II–IV toes. Conclusions. The article describes a clinical case of a child with Apert syndrome. Prenatal diagnosis takes one of the leading places in confirming genetic abnormalities, determining the prognosis for life. Genetic counseling for parents is necessary and important at all stages of pregnancy planning. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies.

Authors:   KP Dnepropetrovsk Regional Children's Clinical Hospital DOS, Dnipro, Ukraine, Vlasov A.A.
Published: February 2021

Congenital defects are more common in newborns and children of the first year of life and require surgical correction in the first hours, days of life. Surgical interventions against the background of serious diseases and malformations can lead to catabolic stress, circulatory and respiratory disorders, metabolism, water-electrolyte, protein and acid-base states, which are reflected in the indicators of vital functions. Purpose — to conduct a clinical analysis of indicators of vital functions in newborns and infants with congenital surgical pathology with various types of combined anesthesia. Materials and methods. A retrospective study included 150 newborns and infants with congenital malformations of the surgical profile, depending on the anesthesia (inhalation + regional anesthesia — group І (50 newborns); inhalation + intravenous anesthesia — group ІІ (50 newborns); total intravenous — group III (50 newborns)). The parameters of peripheral and cerebral oximetry, blood pressure, heart rate and respiration were analyzed. Results. The minimum indicator of cerebral oximetry was noted in the left brain hemisphere of children of the ІІ group — 50.57±16.66, which may be an unfavorable prognostic factor in further recovery and influence on the cognitive functions of the child's brain. Peripheral saturation did not critically decrease at all stages of observation. With the exception of the resulting decrease in the indicator in children of group I compared with group III at the stage of induction into anesthesia (97.79±2.45 versus 98.79±1.63, at p=0.0194, respectively) and at the most painful moment of surgical intervention (96.29±3.47 versus 98.10±2.47, with p=0.0368). In children who received combined intravenous anesthesia with two drugs, there was an increase in mean arterial pressure from the beginning of surgical treatment to the child's recovery after surgery (49.49±10.71; 56.18±8.05, respectively, at p<0.01). Conclusions. Among the surveyed groups, the most vulnerable to pathological changes in vital function indicators were children for whom anesthetic support was provided by inhalation anesthesia with sevoran with regional anesthesia. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the author.

Some aspects of the development and correction of secondary exocrine insufficiency of the pancreas in children
Authors:   I. Horbachevsky Ternopil National Medical University, Ukraine, Kinash M.I.
Published: February 2021

Based on the analysis of literature sources, the main causes and mechanisms of the secondary exocrine pancreatic insufficiency in children are highlighted. The main mechanisms of regulation and peculiarities of functional activity of the pancreas in children are discussed. The importance of pancreatic enzymes for physiological digestion of food nutrients as well as for ensuring satisfactory nutritional status of a child is noted. It is shown that the main reason for the development of secondary exocrine insufficiency of the pancreas in children is a violation of the pancreatic enzymes activity in the duodenum. Factors that adversely affect the effectiveness of pancreatic enzymes by disrupting their activation or inactivation in the duodenum have been listed. They include: 1) motility disorders of the gastrointestinal tract; 2) bile acid deficiency; 3) violation of entero-pancreatic regulation of the pancreas; 4) hyperacidic conditions of the stomach and duodenum; 5) intestinal dysbacteriosis; 6) violation of the outflow of pancreatic juice into the duodenum. The mechanisms of negative influence of these factors on the activity of pancreatic enzymes are also revealed. It is noted that the increase in the prevalence of secondary exocrine pancreatic insufficiency is due to the peculiarities of diseases of the digestive system, namely, the combined nature of the lesions of different parts of the gastrointestinal tract. The effective properties of the mini-tablet enzyme preparation, as well as indications for its use are analyzed; the dosage of enzyme preparations for children in accordance with domestic and foreign recommendations was discussed. The list of pathological conditions in which it is advisable to use enzyme preparations, as well as the requirements that must be met when using enzyme preparations to achieve maximum effectiveness during enzyme replacement therapy. The author declares no conflict of interest. Key words: children, exocrine insufficiency of the pancreas, enzyme preparations.
Fascia and tensegrity: The quintessence of a unified systems conception
Authors:   Faculty of Medicine, Dentistry and Clinical Sciences, University of Chester/NTC, 15-16aSt Joseph’s Parade, Dorset St, DO7 FR6C, Dublin, Ireland., Sharkey John
Published: February 2021

The heterogeneous connective tissue fascia is constructed upon a tensegrity-based architecture providing cells and organism’s with stability coupled with mobility. A term coined by Sharkey and Avison “Fasciategrity” used for the first time at the British Fascia Symposium 2018, speaks of the relationship of balance and integrity within the fascial net. Tensegrity construction principles provide an opportunity to deliver, to medical trainees and post-graduate medical specialists, a unified systems conception of living form and function. In this the 21st century anatomists are ready to move away from a mechanical view of the human corpus based on a 17th century model of parts and levers. A new emphasis is required to integrate current models and theories that substantiate fascia as the connected, unifying, continuous universal singularity that permeates the entire soma. Such models and theories are complex, however, with increased crosstalk between experts and professionals in fields of specialty, within scientific disciplines, a new paradigm is emerging. This new unified systems approach to human anatomy and physiology has the potential to impact global healthcare. A unified systems model of human anatomy (with a special focus on the architecture of fascia) is one that is predicated upon a specific ‘nature inspired’ tensegrity architecture utilizing soft matter as the building material during embryonic self-construction. Self-construction leads to emerging transformations that are driven by both genetic and epigenetic stresses [i.e., biochemical and biophysical cues] embracing collective behaviour with emerging small world networks that utilize non-linear dynamics. Time is a key component as self-organization occurs in a hierarchical time-dependent/temporal sequalae. This short paper focuses on the essential architectural characteristics of cells and multi-cellular organisms that supports a living unified system. While the human body is a true reflection of infinity and continuity it also possesses virtual boarders, boundaries and compartmentalization’s. Such virtual borders and boundaries are self-constructed connections, disconnections and compartments necessary for physiology, metabolism and autoimmune responses reflecting evolutionary contingency.

Authors:   Facultad de Odontología de la Universidad Católica de Santa María, Arequipa, Perú., Miranda-Medina Alberto
Published: February 2021

Objective: The purpose of the present study was to determine the association between agenesis of the third molar and other dental anomalies. Materials and Methods: This was an observational, retrospective, cross-sectional and analytical study. The sample included 367 patients, aged 14 to 20 years old with adequate digital panoramic radiography. Patients with syndromes, who had extractions of any third molar and with orthodontic treatment prior to panoramic radiographic examination, were excluded. For data collection, each radiograph was recorded with patient code, sex and age. Results: The prevalence of third molar agenesis was 20.71%. Subsequently, patients were divided into two groups, with agenesis of at least one third molar and a control group; the prevalence of other dental anomalies was 48.69% of third molar agenesis group and 21.31% in the control group. A highly significant association was found between the presence of third molar agenesis and the presence of other tooth abnomalities (p= 0.0000; contingency coefficient = 0.2425).The most frequent dental anomaly was dental inclusion with 20.44% of the population studied; followed by the agenesis of other teeth (7.90%) and finally the presence of supernumerary teeth (1.63%). Conclusions: This study demonstrates that there is an association between third molar agenesis and other dental abnormalities, with a higher prevalence of dental abnormalities in patients with third molar agenesis.

Introduction: There is a high prevalence of enamel caries around brackets due to the young age of the majority of orthodontic patients, and to the difficulty of plaque removal in presence of orthodontic appliances. Recently, protective agents such as bioactive glasses (BGs) were introduced to enhance remineralization and prevent demineralization of tooth structures. This study aimed to assess the shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) with addition of 45S5 BG to enhance its remineralizing potential using two conventional methods. Material and methods: This in-vitro experimental study evaluated three groups (n=20) of orthodontic brackets bonded to enamel using Transbond XT (group 1), light-cure RMGIC (group 2) and RMGIC with BG added (group 3). Samples underwent 7000 thermal cycles and their SBS was measured. The adhesive remnant index (ARI) score was also determined. Quantitative data were analyzed using one-way ANOVA while qualitative data were analyzed using a chi-square test. Discussion: The results showed no significant difference in SBS between study groups, however the ARI scores were significantly different among the groups. The RMGIC group showed the highest ARI while RMGIC doped with BG showed the lowest ARI score. Conclusion: Addition of 30% w/v 45S5 BG to RMGIC does not cause a significant change in SBS of orthodontic brackets bonded to enamel, while resulting in less amount of luting agent remnants on the enamel surface after debonding.

Dana 2. lipnja 2018. godine navršila se deseta obljetnica od smrti mađarsko-francuskog pisca, publicista i povjesničara Ferenca Fejtöa, a 31. kolovoza 2019. stodeseta obljetnica njegova rođenja. Dvostruki jubilej Katedra za hungarologija Filozofskog fakulteta Sveučilišta u Zagrebu prigodno je obilježila manjom znanstvenom konferencijom na kojoj smo željeli evaluirati vrijednost Fejtöva književnog i publicističkog rada, a potom ga staviti i u nova razmatranja. Fejtöv književni prvijenac, djelo Sentimentalno putovanje, koje je na mađarskom jeziku prvi puta objavljeno 1936. godine, a zatim nakon dugog prešućivanja i 1989, da bi od 2003. bilo dostupno i na hrvatskom, posvećeno je Hrvatskoj, odnosno Zagrebu gdje je pisac kao dječak – prije svega u vrijeme školskih praznika – kod roditelja svoje majke proveo ključna razdoblja svoga života. Zagrebački doživljaji imali su na njega snažan utjecaj tijekom cijelog njegova života, pa je tako i kasnije ostao odan Hrvatskoj. Za vrijeme domovinskog rata Fejtö je u francuskom tisku redovito davao glas gledištima koja su podupirala samostalnost Hrvatske. Hrvatska država 2007. godine odlikovala je Fejtöa redom Danice hrvatske s likom Marka Marulića za osobite zasluge u kulturi. Stoga smo smatrali da bi održavanje simpozija i objavljivanje zbornika s izlaganjima koja smo na njemu čuli moglo pridonijeti dostojanstvenom obilježavanju ove dvije obljetnice.

Urinary tract infections (UTIs) represent a serious global health issue, especially due to emerging multidrug-resistant UTI-causing bacteria. Recently, we showed that the human amniotic membrane (hAM) could be a candidate for treatments and prevention of UPEC and Staphylococcus aureus infections. However, its role against multidrug-resistant bacteria, namely methicillin-resistant S. aureus (MRSA), extended-spectrum beta-lactamases (ESBL) producing Escherichia coli and Klebsiella pneumoniae, vancomycin-resistant Enterococci(VRE), carbapenem-resistant Acinetobacter baumannii, and Pseudomonas aeruginosahas not yet been thoroughly explored. Here, we demonstrate for the first time that the hAM homogenate had antibacterial activity against 7 out of 11 tested multidrug-resistant strains, the greatest effect was on MRSA. Using novel approaches, its activity against MRSA was further evaluated in a complex microenvironment of normal and cancerous urinary bladder urothelia. Even short-term incubation in hAM homogenate significantly decreased the number of bacteria in MRSA-infected urothelial models, while it did not affect the viability, number, and ultrastructure of urothelial cells. The hAM patches had no antibacterial activity against any of the tested strains, which further exposes the importance of the hAM preparation. Our study substantially contributes to basic knowledge on the antibacterial activity of hAM and reveals its potential to be used as an antibacterial agent against multidrug-resistant bacteria.
Study of synthesis processes of heat-insulating silicate materials for external protection of steel oil pipelines
Authors: Yatsenko E. A. , Goltsman B. M.
Published: February 2021

Thermal insulation of steel oil pipelines allows to extend their service life and provide optimal characteristics of the petroleum products transportation. Currently used heat-insulating materials do not meet the requirements of durability and fire safety. Their most promising replacement is porous silicate materials, and one of their main advantages is the possibility to use various types of local raw materials. On the basis of the diatomite of the Chernoyarskoe deposit, the initial batch compositions were developed, their synthesis was carried out by the hydrate foaming mechanism, after which the density of the synthesized samples was determined and their internal structure was studied. The effect of each of the batch components on the intensity of melting and foaming of the initial diatomite was established. It was shown that the introduction of sodium hydroxide lowers the melting point, and the removal of chemically bound water during heating allows to obtain a porous structure. Sodium fluoride, which was introduced as flux, significantly reduces the viscosity of diatomite and, accordingly, the melting point. Using the differential thermal analysis, the physicochemical processes occurring during the thermal treatment of samples were investigated. It was found that mass loss is ensured by the removal of physically and chemically bound water at temperatures of 66.8–75.2 °C and 119.5–124.8 °C, respectively. Moreover, for compositions with the addition of sodium hydroxide, the total amount of bound water reaches 22.99–24.25 % due to the dehydration of sodium hydrosilicates. When processing the batches, observed endothermic effects were corresponded to the evaporation of physically and chemically bound water, and the polymorphic β-quartz → α-quartz transformation at 575 °C. The revealed regularities of the mechanism of diatomaceous raw materials foaming of make it possible to optimize the developed compositions and to obtain high-quality heat-insulating material for pipeline protection. The work was supported by the Russian Science Foundation, Project # 18-19-00455 “Development of integrated protection technology for oil and gas pipelines, operated in the Far East of Russia” within the framework of the 2018 competition “Conducting fundamental scientific research and exploratory scientific research by individual scientific groups”.
Effect of laser treatment modes on metal surface marking color

Published: February 2021

The laser beam marking process is considered to be a subject to important scientific research. In this area, there are insufficiently studied problems and concepts requiring their experimental validation and determining the solutions. Upon laser action, the effect of metal surface coloration can be caused by different processes. The most probable is formation of thin oxidic films, although formation of the other compounds is not unlikely as well [1–2]. Under actual values of luminous flux density, however, scanning with laser beam results in occurrence of regular surface roughness. Therefore, the analysis of diffraction effect impact on the image color is also necessary [3–4]. The color images on the metal surface were assessed based on range of colors RAL “Reich Ausschluß für Lieferbedingungen”. In this system, the color space is divided to ranges with identification of each color by its unique index number. When doing research of the metal surface composite regular relief [5] obtained using laser marker, the depth of microroughnesses in differently colored samples was determined. The was performed using non-contact VICWU profilometer. Due to the method of measurement technological specificity, this equipment does not have destructive effect on the object under study. The roughness values (Rz and Ra) of the surfaces under study were measured based on acceptably small areas, thereat the base lines were selected in such way that to consider the surface waviness effect on the roughness values Rz and Ra [6]. The research results demonstrated that change of surface roughness values Ra and Rz by 1.5 times (owing to change of the surface laser treatment mode), changes the specimen metal surface coloration drastically.

Published: February 2021

The article is devoted to the study of environmental problems in the production of steel pipes and the rational use of waste. The relevance of the study lies in the high resource intensity and waste of pipe metallurgy, the classification of steel production and their subsequent redistribution as the first category of environmental hazard and is assigned to the areas of application of the best available technologies. The aim of the article is to analyze the resource intensity and waste production of steel pipes, to study the existing waste management system and its rationality at Russian enterprises. As the main research methods, the IDEF0 modeling methodology was used to visualize the waste management system and to structurize the model for the production of welded pipes taking into account emissions of pollutants, as well as Data Mining technology in the form of a classification and regression tree for studying trends and local patterns in waste management. The tendency of increasing resource intensity at the enterprise of the pipe industry with relative financial instability is revealed. A visualization of the waste management system in the production of steel pipes is proposed, which makes it possible to distinguish the main functional blocks of the incoming and outgoing parts of the waste balance. A model of the processes of production of welded pipes is structured taking into account emissions of polluting substances into the atmosphere and cleaning methods according to the reference book on the best available technologies ITR 27-2017. Based on the constructed decision tree, knowledge was obtained on the trends in the treatment of steel pipe production waste. In order to reduce the level of rejection in the production of steel pipes and minimize the formation of scrap, a project has been proposed on the automation of technical quality control and the implementation of the MES system. The research was carried out within the framework of the grant of the President of the Russian Federation for state support of leading scientific schools of the Russian Federation, project number NSh-2600.2020.6.

Recommender systems solve the current information overload problem in the online world. By predicting and presenting relevant information, web users do not need to waste time searching and browsing for contents that they are interested in. However, in addition to the accurate contents, slogans associated catching the customers’ eyes are worthy of exploration. This study aims to discover the effects of various recommender slogans. Two categories of slogans were designed in the study: slogans associated with customer inputs and slogans associated with price promotion. Actual customers’ webpage clickstreams and purchase decisions were collected from a Taiwanese retail shopping Website. The effects of recommender slogans on product categories are different. Customers generally were drawn by the slogans associated with price promotion. This study brought to light the effects of different slogans on online shoppers. With the empirical findings, this study provides online retailers important guidelines regarding online customers’ behaviors towards the employment of recommender slogans.

AIM: To evaluate the opinion of students about Tele-education in a post-graduate University Master in Interventional Radiology.
METHODS: The core curriculum of the Master is divided into 3 e-Learning modules and 2 e-Learning plus Hands-on Training modules. E-Learning is delivered through a webinar platform that allows to perform a synchronous training providing real-time lectures that are recorded for streaming on a dedicated website. The Hands-on Training is provided on site, assisting interventional radiologists in interventional procedures on patients. An online survey of 12 questions has been prepared to determine the quality of training. Students indicated their level of agreement regarding the impact of eLearning and Hands on Training using a 5-point scale. The mean score of the level of agreement was calculated.
RESULTS: The series include 16 participants. The 62.5% work in a public non-academic Hospital and 80% have already performed 300 interventional procedures as primary operator.
The main advantage of the eLearning module was considered the capability to facilitate the attendance to lectures (68.8%) followed by the low cost training (18.8%), with a good agreement between participants. No students scored the statements as less than 3. The Master fulfilled the learning expectations in 81.3% of cases with a good agreement between participants.
CONCLUSIONS: The participants were highly satisfied and would recommend the Master to other colleagues. The blended type of education of our Master received high appreciation and could be a model to be follow in the future, also in IR.

Authors: Invernizzi-Mendoza Carlos Rafael , Corbeta Humberto
Published: February 2021

La periodontitis crónica es una patología caracterizada por la destrucción de los tejidos de soporte del diente. Existe evidencia científica de la presencia en bolsas periodontales de Pseudomonas aeruginosa, bacteria que altera la microbiota subgingival. Ha sido asociada al fracaso en el tratamiento de la periodontitis y podría constituir un riesgo para la salud general de los pacientes. El objetivo de esta investigación fue determinar la frecuencia de P. aeruginosa en bolsas periodontales de pacientes con periodontitis crónica que acudieron a la cátedra de Periodoncia de la Universidad Autónoma de Asunción. El estudio fue observacional descriptivo de corte transversal, para el mismo fueron seleccionados pacientes con periodontitis crónica que cumplían con los criterios de inclusión. Las piezas dentariasseleccionadas para la toma de muestras fueron aisladas con rollos de algodón estéril, y una vez removida la placa bacteriana supragingival, se retiró la placa subgingival de las bolsas periodontales por medio de curetas de Gracey y se introdujeron en tubos de ensayo que contenían medio de Stuart, para luego llevar las muestras hasta el laboratorio de microbiología para su análisis. Del total de 14 muestras, solo una dio positivo a P. aeruginosa representando el 7,14%. El microrganismo aislado resultó resistente a los antibióticos utilizados como coadyuvantes en el tratamiento de la periodontitis crónica,al igual que en otros trabajos encontrados en la literatura internacional. La presencia de estas bacterias dificulta el control de la enfermedad periodontal y podría significar un riesgo para desarrollar infecciones oportunistas, especialmente en los pacientes inmunodeprimidos.

Authors: Irsadanar Rafyoga Jehan Pratama
Published: February 2021

This research aims to investigate Japan’s motivation to be involved in the South China Sea dispute despite Japan’s far distance from the conflicted area. Utilizing the qualitative research method, this research analyzes Japanese Government official documents and relevant literature to achieve the research objective. The research discovers that Japan’s main interest in the South China Sea is to articulate a safer maritime lane for the sake of its Free and Open Indo-Pacific agenda by balancing China’s assertiveness in the region. Employing a regional security complex framework, this research sees that Japan, by its presence in the South China Sea, tries to intensify the security interaction with Southeast Asian counterparts to expand the Northeast Asian regional subcomplex, aiming to strengthen the perception of China as a threat to Southeast Asian countries. The South China Sea involvement will fortify Japan’s security interlink with Southeast Asian counterparts, balancing China’s expansive trait in the maritime zone, accelerating Tokyo-initiated Free and Open Indo-Pacific vision.

This analysis focuses on the paradiplomatic policies in Indonesia and Korea. The two countries have similar characteristics, namely as unitary state systems, and enacted regional autonomy in the same era, 1998s. This qualitative research aims to examine paradiplomatic types in both countries and why the policies are rationalized. The findings revealed that although both countries are unitary states, paradiplomatic activism runs in different types. Provinces and cities in Indonesia face many restrictions and limitations by national regulations, while regional governments in Korea have more discretions and authorities to practice paradiplomacy around the world. The research finding also portrayed several provinces in Indonesia instrumentalizing paradiplomacy as instruments to provide international recognitions related to self-determination, and this similar fact is not met in Korea. This paper argues that the different types of paradiplomatic policies in both countries are influenced by domestic political conditions and typically influenced by the presence or absence of regional movements.
