Authors: Tang Lin
Published: November 2021

In order to overcome the problems of high data storage occupancy and long encryption time in traditional integrity protection methods for trusted data of IoT node, this paper proposes an integrity protection method for trusted data of IoT node based on transfer learning. Through the transfer learning algorithm, the data characteristics of the IoT node is obtained, the feature mapping function in the common characteristics of the node data is set to complete the classification of the complete data and incomplete data in the IoT nodes. The data of the IoT nodes is input into the data processing database to verify its security, eliminate the node data with low security, and integrate the security data and the complete data. On this basis, homomorphic encryption algorithm is used to encrypt the trusted data of IoT nodes, and embedded processor is added to the IoT to realize data integrity protection. The experimental results show that: after using the proposed method to protect the integrity of trusted data of IoT nodes, the data storage occupancy rate is only about 3.5%, the shortest time-consuming of trusted data encryption of IoT nodes is about 3 s, and the work efficiency is high.

Authors: Hasritawati  , Barirah Madeni
Published: November 2021

Background. Mortality and morbidity in pregnant and maternity women is a big problem in developing countries. In poor countries, about 25-50% of deaths of women of childbearing age are caused by pregnancy-related causes. It is estimated that every year 585,000 women die from pregnancy and childbirth. 99% of these deaths occur in developing countries. According to WHO, 60-80% of maternal deaths are caused by bleeding during childbirth, obstructed labor, sepsis, high blood pressure during pregnancy, and complications from unsafe abortion. The purpose of this study was to determine the relationship between normal delivery care (APN) training on the knowledge and attitudes of midwives at the Bebesen Health Center, Bebesen District, Central Aceh Regency in 2020.

Methods. The research method uses an analytical survey method with a cross sectional approach, which is a study to study the dynamics of the correlation between risk factors and effects, by approaching, observing or collecting data at once. The population in this study was all 63 midwives. The sampling method uses a total sampling technique that uses all members of the population as a sample. Data collection was carried out from November 14-16, 2020.

Results. The results showed that from the analysis obtained a value for the p-value of good knowledge as many as 20 respondents (31.7%) and a positive attitude that is as many as 32 respondents (50.8%).

Conclusion. There is a relationship between normal delivery care training (APN) with knowledge with a p value of 0.014 (p < 0.05) and normal delivery care (APN) with changes in the attitude of midwives with a p value of 0.00 (p < 0.05) in Bebesen Public Health Center, Bebesen District, Central Aceh Regency.

Authors: Şener Alp , Pamukçu Günaydın Gül , Tanrıverdi Fatih
Published: November 2021

Objective: In cardiac arrest cases, high quality cardiopulmonary resuscitation and effective chest compression are vital issues in improving survival with good neurological outcomes. In this study, we investigated the effect of mechanical chest compression devices on 30- day survival in out-of-hospital cardiac arrest.

Materials and Methods: This retrospective case-control study was performed on patients who were over 18 years of age and admitted to the emergency department for cardiac arrest between January 1, 2016 and January 15, 2018. Manual chest compression was performed to the patients before January 15, 2017, and mechanical chest compression was performed after this date. Return of spontaneous circulation, hospital discharge, and 30-day survival rates were compared between the groups of patients in terms of chest compression type. In this study, the LUCAS-2 model piston-based mechanical chest compression device was used for mechanical chest compressions.

Results: The rate of return of spontaneous circulation was significantly lower in the mechanical chest compression group (11.1% vs 33.1%; p < 0.001). The 30-day survival rate was higher in the manual chest compression group (6.8% vs 3.7%); however, this difference was not statistically significant (p = 0.542). Furthermore, 30-day survival was 0% in the trauma group and 0.6% in the patient group who underwent cardiopulmonary resuscitation for over 20 minutes.

Conclusion: It can be seen that the effect of mechanical chest compression on survival is controversial; studies on this issue should continue and, furthermore, studies on the contribution of mechanical chest compression on labor loss should be conducted.

Heavy transport aircraft are built and operated by US airlines (C-5A, C-5B, B-747-400), the European Concern Airbus (A-380), and the ANTONOV domestic state-owned enterprise. Such heavy aircraft as An-22, An-124 and An-225 have received worldwide recognition as the most efficient in their class [1, 2, 3]. It should be noted that such outstanding compatriots as O. K. Antonov, P. V. Balabuev, S. A. Bychkov, V. I. Tolmachev, V.F.Eroshin, O.K.Bogdanov made a decisive contribution to their improvement (including formation of mass characteristics).The main path of development of domestic heavy transport aircraft is to create modifications that meet the ever-increasing requirements of the time and customers to improve their transport and economic performance.The article shows that one of the ways to improve this type aircraft efficiency is the formation of their mass characteristics (i.e., mass of the aircraft modification itself and its individual units), which significantly affect all flight technical and economic parameters.It is proposed to take into account possible changes in four groups of parameters when assessing the starting mass (formed at the initial stages of creating a modification):T - a group of parameters that determine the level of requirements for a new modification;U - a group of parameters that determine the achievement of the stated goals at the stages of creation and operation of the modification;O - a group of parameters that determine the appearance of the future modification;P - a group of parameters that determine the mass and its density in the created modification.Division of the parameters into four groups makes it possible to evaluate and minimize the effect of the objective "square - cube" law on the mass gain in the design, production of a prototype and its flight tests and to represent it in the form of the starting mass of the modification (m0).The effectiveness of using the proposed approach to the formation of mass characteristics is shown on examples of the development of modifications of the An-124-100M and An-124-100M-150 airplanes.A distinctive feature of these modifications are: they were developed twenty years after creation of the base An-124 aircraft, carrying capacity has been increased by 30 tons, takeoff weight has been increased by 7%, the wing area, as well as the takeoff roll and landing run remained unchanged. The empty aircraft mass also remained unchanged, which indicates a special approach to the formation of mass characteristics. At the same time, in these modifications, the carrying capacity and flight performance increased by 25%, which is the highest achievement in the practice of creating aircraft of this type

It is shown that the development of the concept of metrological support for the creation of composite structures of aircraft aggregates of the transport category and their support at all stages of the existence of an aircraft should be based on the formation of a complex criterion for the effectiveness of the use of polymer composite materials. It is noted that the effectiveness of a structure made of polymer composite materials is provided by various methods, methods and technical means of metrology. The structure of a complex of studies aimed at developing the concept of metrological support is discussed, the first point of which is to analyze the types of metrological characteristics and the scope of work to determine them at the main stages of the existence of composite structures of aircraft aggregates of the transport category. Based on the analysis of numerous publications on the problem of metrological support of the main stages of creating technical products, the main types of measurements of the metrological characteristics of composite structures of aircraft aggregates of the transport category have been established, and the composition of the nomenclature of works on metrological support of the main stages of the existence of these structures has been determined. 12 main types of measurements of parameters have been identified, on which the whole variety of production physical quantities and the description of the properties and characteristics of structures of aircraft aggregates made of polymer composite materials are based. The composition of the main works on the metrological support of the four stages of the existence of the aircraft is revealed: design, production, operation and disposal of composite structures formed into systems of sequential blocks for performing these works. It is shown that the tasks of metrological support at the facility manufacturers should be solved during the technological preparation of serial production and testing of the installation series of products, and also take into account the peculiarities of aircraft operation and disposal of composite structural elements in terms of work safety and economic efficiency of their results. An enlarged sequence has been established for organizing work on metrological support for measuring the properties of composite structures of aircraft aggregates at aviation enterprises. The results presented in the first approximation provide a solution to practically important aspects of the problem under discussion.

Authors: Wilczewski Michał , Gorbaniuk Oleg , Mughan Terry , Wilczewska Ewelina
Published: November 2021

This research investigates the student online learning experience (SOLE) during the 2020 spring Covid-19 pandemic. We collected quantitative data through an online survey from 362 international and 488 domestic students at a large Polish University. Correlation and path analysis within a conceptual model of SOLE and its academic outcomes established that (1) SOLE explained adjustment, performance, satisfaction, and loyalty, (2) academic adjustment predicts performance, satisfaction, and loyalty, (3) that academic performance and satisfaction predict student loyalty, and (4) that academic performance predicts satisfaction. Interestingly, time spent in quarantine/self-isolation did not exert any effect on academic outcomes in SOLE. Moreover, qualitative data collected via narrative interviews with 13 international and domestic students developed our understanding of SOLE and its outcomes. We propose some research and practice implications for universities to enhance SOLE.

Published: November 2021

BACKGROUND: End of life care is increasingly becoming complex and protracted with the advances in critical care medicine.(1) Prolongation of life in critically ill elderly comes with multiple issues related to ethics, quality of life and autonomy of the patient, care giver burden, financial issues, and interplay of complex medical issues affecting the well being of the patient and the caregiver.(2) Palliative Psychiatry is increasingly being recognised as a major subspecialty when it comes to dealing with these situations.(3) There is a high incidence of delirium in end stage palliative care with a prevalence as high as 88%(4). Here we report a patient with multiple critical medical issues who suffered with severe and protracted delirium. He was brought in owing to unmanageable aggression and sleep wake cycle reversal which made the caregivers totally helpless. The complexities in his care and considering the family’s wishes for not having any invasive treatment procedures are being discussed.
Síndrome de Tapia bilateral após cirurgia de avanço maxilomandibular
Authors: Silva Alexandre Augusto Ferreira da , Rocha Roberto de Oliveira , Mariano Ronaldo Célio
Published: November 2021

Lesões do nervo hipoglosso e laríngeo, recorrente em suas vias extracranianas unilaterais ou bilaterais, causam um déficit motor na língua com perda transitória, parcial ou total da fala, que pode estar associada à disfagia leve ou grave, caracterizando a síndrome de Tapia. Essa condição incomum costuma estar relacionada à manipulação das vias aéreas durante o ato anestésico-cirúrgico, sendo poucos os casos na literatura correlacionados com cirurgias maxilofaciais, o que explica, em parte, o desconhecimento dessa complicação por um número significativo de profissionais. Descrevemos um relato de caso de síndrome de Tapia bilateral estabelecida após procedimento para avanço maxilomandibular. Trata-se de um paciente do gênero masculino, 55 anos, com diagnóstico de retrognatismo e retromaxilismo. O paciente foi submetido a um avanço maxilomandibular com intubação nasotraqueal. Evoluiu com síndrome de Tapia bilateral, recuperando-se dos sinais e sintomas desta complicação, sendo reoperado para corrigir resultados estéticos obtidos na primeira intervenção que estava abaixo do aceitável, não evoluindo após esta segunda cirurgia com a síndrome. Concluímos que medidas preventivas devem ser tomadas, como evitar movimentos bruscos na região da cabeça e hiperextensão prolongada do pescoço durante a cirurgia, minimizando o trauma da cânula traqueal sobre os tecidos que recobrem os nervos hipoglosso e laríngeo recorrente.

Authors: Bonsay Jamielyn , Cruz Abigail P. , Firozi Homa C. , Camaro And Peter Jeff C.
Published: November 2021

Artificial intelligence is designed to generate technologies that potentially increase productivity and economic welfare. This study analyzes the relationship between GDP and high-technology exports, GDP per person employed, and unemployment rate in China, India, Japan, and Singapore. Recent concerns on technological unemployment claim that artificial intelligence disrupts the labor market which decreases employment over time. Using the multiple regression analysis, this study proved that Japan comparatively has better utilization of AI and labor productivity as all independent variables show significance to the GDP. Labor productivity in all countries is positively related to GDP. However, China and India showed signs of improper AI utilization as technological unemployment occurred. The unemployment rate in China is insignificant to its GDP, while India's unemployment rate is positively related to GDP, hence the jobless growth. In Singapore, the insignificance of high-tech exports to GDP is due to its lack of R&D investments these recent years. The results suggest that AI escalates growth through proper utilization trade liberalization, as exercised by Japan, as it helps the economy to be open and flexible to various free trade agreements which facilitates technological progress and enables the opening of new markets for growth and expansion, especially of artificial intelligence, which attracts and encourage foreign direct investments that will cater technology transfer, creation of new jobs, and economic growth.

The research work was conducted for isolation and identification of potential pathogenic bacteria from blow fly (Calliphora spp.) and to investigate their antibiotic susceptibility. For this purpose, 20 blow flies were collected from 4 selected areas (Curzon Hall, Dhaka Medical College Hospital, Fruit Store and Fish Market) of Dhaka city. A total of 40 samples (20 from external surface and 20 from alimentary gut homogenates) were prepared from the blow flies. Among the total 20 flies, 3(15%) were collected from Curzon Hall and 5(12.5%) isolates were obtained from them; 6(30%) flies were collected from DMCH which had 11(27.5%) isolates; 5(25%) flies were collected from fruit stores and 10(25%) isolates were collected from there; 6(30%) flies were collected from fish market and 14(35%) isolates were collected from there. The isolated bacteria were presumptively identified as Escherichia coli, 12 (30%); Salmonella spp., 8 (20%); Shigella spp., 4(10%); Enterobacter spp., 3 (7.5%); Klebsiella spp., 2 (5%); Bacillus spp., 7 (17.5%) and Staphylococcus spp., 4 (10%) in number which were based on morphology as observed under microscope as well as cultural and biochemical properties. All of these isolates were resistant to various antibiotics. Bacterial susceptibility showed that E. coli isolates were highly resistant (66.6%) to Penicillin, Salmonella spp. mostly resistant (62.5%) to Penicillin and Tetracycline. Klebsiella spp. Isolates were 100% resistant to Penicillin and 100% sensitive to Ciprofloxacin, Imipenem and Tetracycline. In case of Shigella spp. and Enterobacter spp., 75% and 100% isolates were resistant to Penicillin respectively. Among the Staphylococcus spp. isolates, 75% were resistant to Ampicillin and Penicillin. In case of Bacillus spp. isolates, 57.2% were resistant to Penicillin and 100% sensitive to Imipenem. Antibiotic resistance of these species affect our human health also. This study demonstrated the potential of blow flies as a vector of various pathogenic microorganisms and a mode of transmission of antibiotic resistance.

Tenualosa ilisha (Hamilton, 1822), commonly known as Hilsha shad is a valuable and highly acceptable species in terms of their high flavored properties. Hilsha shad has striking morpho-genetical adaptation to heterogeneous habitats across their migratory routes. Cytogenetic analysis demonstrates the changes in chromosomes. But none was focused on the cytogenetic analysis of T. ilisha in Bangladesh. T. ilisha was found to possess 2n = 42 number of chromosomes along with a karyotype formula: 1M + 31m + 8sm + 2st using giemsa staining technique. The results demonstrated ‘diffuse type of interphase nuclei, co-existence of continuous type and interstitial type of prophase chromosomes respectively. No heteromorphic sex chromosomes were determined cytologically. The presence of diverse types of chromosomes based on centromeric position, gradual decrease in total haploid chromosome complement, mean centromeric asymmetry, coefficient of variation of chromosome length and Stebbins’s classification highlighted its asymmetry in karyotype with advance nature. Therefore, the elemental karyological data will offer information for the proper identification, cytotaxonomical classification, expanding productivity and preservation of genetic resources ofT. ilisha.

Published: November 2021

The study was carried out to survey the fresh and marine water fishes sold out in three markets of Chattagram city and socioeconomic condition of the fish retailers. Overall 29 fresh water and 24 marine water fish species were found to be sold in the three markets. Prices of fishes were higher in Kazirdewri Bazar followed by Riazuddin Bazar and Bohaddarhat Bazar. Data of fish retailers were collected through questionnaires in terms of age, income source, living standards, family size, financial facilities, literacy and education. Sole income came from fish business for 97% of the fish retailers, whilst 3% of the retailers did other business as well. Among 45 retailers interviewed, 40% were below 45 years, 53% were between 45-55 years and remaining 7% were above 55 years age. For coping with the business, 15% of the retailers were self-sufficient, 53% took loan from bank, whilst 32% took loan from local money lenders. Of the fish retailers, 34% was illiterate and 66% was literate, where 36% received up to primary level, 16% secondary level, 10% S.S.C and 4% H.S.C levels of education. In comparison with their education status their children were more educated (93%). Although their income was low, they tried to make their children educated, which is a good sign for our education sector. Transport cost, unhygienic market place, lack of sanitary facilities, poor ice-supply, exploitation by the middlemen, lack of proper management, lack of capital and the political disturbances were the common constraints of fish marketing. Necessary measures were recommended to overcome these problems.

Institutional Economy Development Problems
Authors: Yerznkyan Bagrat H.
Published: November 2021

The development of institutionalism was not limited to the transition from the old theory to the new one: time is changing, the behavior of economic agents – ​carriers, voluntary or involuntary, of the institutions, whether formal or informal, is changing, – ​institutions that, in turn, are themselves the object of changes. This nature of the object under study poses a difficult task for researchers: to identify, with the help of changing (developing, adapting) tools, the essence of the modern institutions and the ones that can take place in the future, which is in a state of permanent development (evolution). The article describes the system logic of institutions, the reasons for institutional changes, especially caused by the current pandemic, highlights the problems and prospects for the development of the institutional economics from an ecosystem perspective. The latter circumstance presupposes going beyond the purely systemic approach to the study of the institutional system by including the features of the interaction of the system under study with the relevant metasystem, which forms a functional unity with the system and, therefore, is interpreted in aggregate as an ecosystem.

This set of ideas is guided by people working in government bodies, and first of all, the heads of these bodies. It is shown that the authorities take steps to develop the parameters of economic development and ensure compliance with these parameters by all elements of the system on the basis of the existing ideology. It is noted that from the point of view of the system approach, the basic elements of the system of economic relations are households. Therefore, the parameters of the “economic relations” system development should characterize the improvement of the condition of each household. It is proved that the existing de facto ideology of enrichment and the corresponding economic policy does not and will not be able to ensure sustainable economic growth, since they are not aimed at ensuring the growth of the well-being of all households. The vector of changes in economic policy is indicated in the case of legislative and institutional consolidation of a new ideology – ​“improving the welfare of all households”. It is shown that such a change in ideology will necessarily entail a demand for scientific justification of the nomenclature and assortment of household needs and the necessary ways to ensure them. On the basis of a systematic approach, a forecast is given of what may happen in the country if these ideological changes are not made.

La presente contribución estima la Intensidad de Isla de Calor Urbano superficial (SUHI) durante el periodo 2001 – 2016 para el Area Metropolitana de Cuzco (AMC), localizado en Perú en el departamento de Cuzco. Para cuantificar la SUHI, se usó 2 métodos: el primero es el método de Streutker  y el segundo método propuesto por Jose Flores (método de cuantil). Donde se utilizó data de sensoramiento remoto de LST mensual y producto anual de tipo de cobertura de suelo (Land Cover Type) a 0.050 de resolución, obtenido del sensor MODIS a bordo del satélite TERRA y AQUA. En el AMC, en los periodos diurnos, el SUHI máximo muestra los valores máximos en marzo (4.6 C) y valores mínimos en julio (0.5 C) y la SUHI nocturnas presenta valores máximos en octubre (2.6 C) y valores mínimos en marzo (1.7 C) utilizando el método de cuantiles, ya que el área metropolitana de Cuzco no se ajusta a una superficie gaussiana.

Los estresores académicos junto con la acumulación de diferentes tensiones de la vida cotidiana de los estudiantes son causantes de estrés, lo cual constituye una problemática importante a nivel mundial, sobre todo en el ambiente universitario. El objetivo de esta investigación fue determinar si las sobrecargas académicas son los estresores académicos que más influyen en los niveles de estrés de los estudiantes dentro del ambiente universitario. El estudio se realiza con base en un enfoque empírico analítico, de tipo descriptivo y transversal, con el que se establecieron las preguntas para realizar la encuesta proveniente del Inventario de Estrés Académico (IEA), utilizando una escala de respuesta tipo Likert con 5 opciones. La misma se aplicó a estudiantes pertenecientes a las carreras de la Facultad de Ingeniería Industrial, siendo el 60,3% mujeres y 39,7% varones. Con los resultados se obtuvo que los estresores académicos más influyentes en el estrés de los estudiantes fueron la sobrecarga académica con un porcentaje del 18,8%, la falta de tiempo para cumplir con las actividades académicas con 15,7% y el hacer un parcial representó un 9,3%, siendo el cansancio y la fatiga la manifestación física más presentada en los estudiantes, y la manifestación emocional vendría siendo el temor por no cumplir con las obligaciones.

Published: November 2021

This paper investigates the impact of the Learning Resource Centre activities of Westminster International University Tashkent (WIUT) graduated students on the labour market outcome. WIUT library provides a learning environment that helps students to create practical teams and individual projects to support the agenda of employability. The study aims to clarify the relationship between library activities and labour market outcomes. This proposes the improvement of a commercial responsiveness workshop, in collaboration with other services, and alumni voices in an employability guide. A quantitative research approach was employed; an online survey questionnaire was distributed to alumni students to obtain the data. It was a semi-structured questionnaire designed using a Likert Scale to collect data from 607 graduates. The study revealed that LRC activities have a significant impact on labour market outcomes for students. LRC activities such as presentation skills, information technology skills, problem-solving skills, research skills were mostly expected in the labour market. Research limitations– The study was focused only on graduates of WIUT, which may limit the generalizability. Therefore, the researcher proposed to study and compare other graduates of universities in Uzbekistan. The insights are valuable for planning the curriculum of LRC activities and developing teaching practices at WIUT. Moreover, current and graduate students can learn market-oriented skills and labour market demands. This is the first-ever study in Uzbekistan that explores the relationship of university library activities on employability skills of alumni.

Published: November 2021

Introdução: O processo de envelhecimento é um fator de risco para doenças neurológicas, como a doença de Alzheimer. O ômega 3 é um ácido graxo presente nas membranas neuronais e desempenha um papel fundamental no metabolismo do tecido nervoso. Objetivo: descrever os efeitos do uso do ômega 3 no tratamento de pacientes com Doença de Alzheimer. Método: trata-se de uma revisão integrativa desenvolvida nas bases de dados da LILACS, MEDLINE E EMBASE por meio dos descritores: Alzheimer Disease, Omega-3 Fatty Acids, Therapeutics e Disease Prevention . Foram localizados 483 artigos, mas 476 não atenderam aos critérios de elegibilidade e foram excluídos. Realizou-se uma análise comparativa dos dados extraídos dos artigos selecionados para a amostra final. Resultados: A amostra foi composta por sete artigos. Houve prevalência do uso de cápsulas contendo 800 mg de ácido docosa-hexaenóico e 225 mg de ácido eicosapentaenóico. Os ácidos graxos demonstraram ter potencial de reduzir o acúmulo de proteínas beta amilóide em regiões corticais do cérebro ou até a prevenção de formação, além de aumentar a espessura cortical. Conclusão: A suplementação com ômega 3 possui efeitos benéficos no tratamento de pacientes com alzheimer ao possuir características neuroprotetoras no combate a alterações morfofisiológicas que normalmente ocorrem no ambiente patológico.
