Published: March 2022

The article comprehends the issues of interaction, the connection of civilization and philosophy, the relationship of culture and philosophy, culture and civilization. A comparative analysis of the concepts of civilized man, individual, personality, social identity is carried out, the place of philosophy in the formation of a civilized society is determined. Man is the architect of the universe. He has shaped, changed and transformed the world with his actions for ages. The material and spiritual riches it has brought together have been collected under the title of civilization and it has become a heritage transferred from generation to generation. The protector of this heritage is philosophy. Philosophy assumed the role of guiding people in understanding the universe, led by the civilizations developed and transferred their existence to the next generation. Likewise, civilizations contributed to the development of philosophical thought with their accumulation. Great civilizations were founded on solid philosophies. Human being is an entity that lives in social life and under the influence of geographical conditions. It has developed a world of thought and established civilizations by adding environmental conditions to its accumulation in society and culture, which is a living organism. In the birth of philosophy, these three elements; The impact of human, community and environmental factors is very important. Within the concept of civilization, within a material and spiritual accumulation of a society; culture, art, literature is also basically the product of a philosophy. Between these two concepts there is a structure that is fed from each other in this context. Values are the basis of social development. Any civilization is also based on values. The role of philosophy in the preservation of values and their transmission to the next generations is very important. In the field of philosophy, our whole life is displayed. It, like a mirror, allows you to see a complete image, moving from the particular to the general. And we designate this integral image with the concept of civilization.

Published: March 2022

Introduction: Male infertility (MI) in about 50% of couples is constituted due to genetic, hormonal, and epigenetic factors. Almost 10% of it is contributed to genetic anomalies. Objectives: This study was undertaken in 787 males with infertility and the impacts of the type of translocations in these cases were studied in relation to MI. Materials and Methods: Five milliliters (ml) of blood were drawn from referred cases suspected with MI and were used for cytogenetic analysis with Giemsa stain following International System for Human Cytogenetic Nomenclature. Results: Of 6142 referral cases, 787 were detected with MI (787/6142; 12.8%). Forty-four translocations (44/787; 5.6%) were detected in 787 infertile men. Other chromosomal abnormalities were 21% (167/787) in them. Among all translocations, an autosome-autosomal translocations were higher in frequency (24/787; 3.1%) than Robertsonian (15/787; 1.9%) and autogonosomal translocations (5/787; 0.6%). Few translocations seemed to be rare as our knowledge is concerned. Maharashtra had high frequency of translocations followed by Delhi union territory (UT) and Gujarat (07 each) and other states. Most of the translocations were related to infertility. Seven males had primary infertility (7/44) and six with secondary type (6/44) in this study. Conclusions: These reciprocal translocations are important in causation of infertility affecting testicular spermatogenesis. Few are rare in our study. Such cases are clinically suggested for counseling before adopting assisted reproductive technologies.

Authors:   Universidad Autónoma de Coahuila, México, Arteaga Botello Nelson
Published: March 2022

En este trabajo se analizan distintas interpretaciones de la franquicia Alien y cómo dividen al mundo respecto a temas como la explotación económica, la tecnología y la otredad. La sociología cultural permite comprender cómo las interpretaciones se articulan a través de conjuntos binarios que ven al mismo tiempo la franquicia como una crítica y una apología de: a) el racionalismo capitalista colonial y tecnológico, b) la exclusión del otro y lo monstruoso, y c) el feminismo, la identidad sexual y de género. Las interpretaciones se analizan como condensaciones sobre las esperanzas y los temores en relación con los procesos sociales contemporáneos. La disputa por el control del sentido de Alien permite comprender cómo se articulan los temores y las esperanzas sobre la racionalidad económica y tecnológica y sobre las relaciones de género.

Published: March 2022

In the modern world different products and goods are available throughout the world thanks to the complex supply chain system. Often products are transported on long journeys with different transportation systems where products can be damaged or spoiled. Smart Sticker is a concept for product environmental condition monitoring that can resolve some problems in the supply chain. Smart Sticker will record product environmental data in the supply chain and enable producer/consumer product monitoring. Because of ultra-low power design, Smart Sticker component selection must satisfy ultra-low power specifications, besides standard accuracy, and real-time implementation. In this paper we give an overview of the necessary measured environmental parameters and the selection of sensors with emphasis on low power design. We provided a model for the calculation of the maximum operating time, which is applied for the two Smart Sticker instances with significantly different energy consumptions. In the worst-case scenario operation time is 198 days which can be increased with a higher capacity battery

Published: March 2022

The researches have been made on G-protein coupled receptors (GPCRs) over the long-ago decades. GPCR is also named as 7-transmembrane (7TM) receptor. According to biological prospective GPCRs consist of large protein family with respective subfamilies and are mediated by different physiological phenomena like taste, smell, vision etc. The main functionality of these 7TM receptors is signal transduction among various cells. In human genome, cell membrane plays significant role. All cells are made up of trillion of cells and have dissimilar functionality. Cell membrane composed of different components. GPCRs are reported to be modulated by membrane cholesterol by interacting with cholesterol recognition amino acid consensus (L/V-X (1-5)-Y-X (1-5)-R/K) (CRAC) or reverse orientation of CRAC (R/K-X (1-5)-Y-X (1-5)-L/V) (CARC) motifs present in the TM helices. Among all, cholesterol is one who is regulated by membrane proteins. Here we took GPCR as membrane proteins and this protein modulates membrane cholesterol. According to cell biology, GPCR regulates a wide diversity of vital cellular processes and are targeted by a huge fraction of approved drugs. In this paper we have concentrated our investigation on membrane protein with membrane cholesterol. A hybrid algorithm consisting of spectral clustering and support vector machine is proposed for prediction of membrane cholesterol with GPCR. Spectral clustering uses graph nodes for calculating the cluster points and also it considers other concept such as similarity matrix, low-dimensional space for projecting the data points and upon this parameter at last construct the cluster centre. Supervised learning method is used for solving regression and classification problems. From the analysis we found that our result shows better prediction accuracy in terms of time complexity when compared with two existing models such as fuzzy c-means (FCM) and rough set with FCM model

The purpose of this article to find out and understand related to development through investments that can achieve people's welfare, and analyze the reorientation of sustainable development principles in investing by utilizing pro-environment natural resources. This result is reorientation the principle of sustainable development should be done by integrating the activities of the investment policy of natural resources into the economic system and environmental based budget. The conclusions are first, the perspective of the Indonesian government in development through investments isn't directly proportional to the welfare of the people. Current developments tend to the developmental and anthropocentrism paradigms; and secondly, reorientation on the principle of sustainable development since changing the government's perspective on development using an ecocentrism paradigm, and integrating natural resource investment activities into the economic system or environment-based budgets.
Developing Innovative Financing Scheme for Leveraging Energy Efficiency Deployment in Indonesia
Authors: Kurniawan Robi , Kurniawan Irwan Wahyu
Published: March 2022

Having great potential, a mechanism that can leverage private involvement in energy efficiency deployment should be developed in emerging markets such as Indonesia. This study aimed to formulate an implementable financial innovative scheme for leveraging energy efficiency deployment in the country. Scrutinizing relevant studies and interviewing relevant stakeholders such as the Ministry of Finance, Ministry of Energy and the Financial Institution, we formulated a blended financial scheme for an energy efficiency project. Main stakeholders will include the scheme, including fund facilitator, trustee, custodian bank and energy user/energy service company. In our proposed scheme, Indonesia Environment Fund (IEF) is obtained the fund from the fund facilitator. IEF will act as a trustee that delivers funds for the Custodian Bank. The bank will disburse the fund to the feasible energy efficiency project or through an energy service company. In this scheme, since banks get lower interest rate funds from the trustee, they will disburse the fund to the customer with a lower interest rate than a commercial rate. Consumers utilize the fund for their energy efficiency projects. Utilizing a proposed scheme to an energy efficiency project case study, it is found that the proposed scheme potentially reduces the interest rate and leverages the project viability in a certain condition. Doing the sensitivity analysis by comparing interest rate and IRR (Internal Rate of Return) in several loan periods, we found that the shorter period of the loan and lower interest rate can improve projects feasibility. For instance, simulating a 5-year loan, it is found that reducing the interest rate from 12% to 7% could improve up to 2% IRR of the project case. Therefore, the scheme can catalyze private-sector investments mobilization for energy efficiency deployment in the country. Furthermore, it can support the country's energy security enhancement.
DETECting the “noirification” of European popular narratives across film, fiction and television
Authors: Pagello Federico
Published: March 2022

The article explores the transcultural dimension of European crime narratives by looking at the specific role of cinema in this context. Building on the research conducted by DETECt scholars in different areas of contemporary popular culture—especially literature and television—it first discusses the link between the more and more widespread use of the “noir” label and the increasing cultural legitimation of the crime genre. The article then argues that this phenomenon echoes the emergence of a new “European quality crime film” in recent years. While stressing the potential contribution of the genre to the circulation of European cinema, the evident limits of its impact in this field are also examined. Finally, it looks more closely at the transnational circulation of contemporary Italian crime films to assess to what extent they have been able to find a transnational audience on a continental level. In this context, the importance to look beyond theatrical distribution and the centrality of intermedial exchanges are highlighted, indicating new directions for research.

Authors: Zhyhadlo Olena Y.
Published: March 2022

The research explores the potential of online gamified resources used as means of formative assessment during foreign language lessons in higher education institutions. The use of any game-based tools with certain game elements which can be integrated into conventional or online teaching and learning is considered to be characteristic of game-based approach to teaching and learning. The study established the main elements of educational gamified tools. These elements of game mechanics are capable of triggering such senses and emotions as reward, challenge, achievement, competition and positive emotions. A number of theoretical and empirical research methods have been applied to analyse and prove the benefits of digital interactive tools as effective means of formative assessment of students’ progress in mastering a foreign language and an invaluable source for constructive feedback for the development of students’ foreign language competence. Three online game-based learning platforms, Kahoot!, Wordwall and Mentimeter, have been selected for analysis. Being compatible with popular video conferencing solutions, these tools proved to be easy to master and suitable for the tasks and purposes of foreign language lessons. The author maintains that activities devised with the help of Wordwall, Kahoot! and Mentimeter can be employed at foreign language lessons to practise vocabulary and grammar, to consolidate the material and reinforce learning, to assess the knowledge of the syllabus vocabulary and grammar, to check comprehension of texts, to revise for tests. The analysis of game mechanics proves that online game-based tools facilitate mastering knowledge and skills by means of influencing students’ motivational sphere through creating enjoyable learning environment and providing prompt feedback. Another major advantage of digital gamified resources is supplying the educator with a variety of instruction tools and assessment techniques to meet individual student needs. Detailed reports on student performance in activities available in the toolbar of these platforms offer useful data for analysis and creating an effective teacher feedback aimed at developing students’ foreign language competence.

Published: March 2022

The issues of possibility of application of the code reuse mechanism in the process of designing and developing software of knowledge-oriented systems have been considered. The necessity of an individual research on the development of software for analytical and information resources that provide support to all participants in the process of knowledge-oriented systems software development has been proved. The necessity of using the mechanisms of reuse of previously developed and verified program code as an element of the information resource has been shown. In frame of the developed method of improving the reliability of knowledge-oriented systems software through the of code reuse mechanisms, a new visual form of function libraries representation in the shape of a single software shell has been proposed. As a basic framework for solving the problem of information resource development, usage of Unified Modeling Language (UML), which is based on the paradigm of object-oriented programming has been proposed. Mentioned choice is justified by the fact that UML is an integral part of a unified software development process and is essentially an open standard that uses graphical notation to create an abstract model of the system. The obtained theoretical provisions are imaged into a running example, which shows one of the possible options for organizing libraries of functions as an element of the information resource. The use case diagrams, interaction diagrams, sequence diagrams, class diagrams have been developed and justified. Based on the obtained practical results, a block diagram of the method, which, in contrast to existing solutions, includes a procedure for generating of proofreads for basic UML-diagrams in accordance with requirements of the programming environments has been proposed.

Objective: The infectious corona virus, COVID-19 has high case mortality in those whom suffer with severe symptoms requiring hospitalisation. A major problem associated with COVID-19 is the spread of infection by a-symptomatic carriers, or those with mild symptoms. We aim to determine the antibody prevalence in a professional Welsh cohort and begin to explore the longevity of COVID-19 antibodies. Methods: 739 Cardiff Metropolitan University staff members took part in an observational study to determine the prevalence of COVID-19 antibodies in a two-phase, single cohort study. All participants were tested for IgM and IgG antibodies against COVID-19 using a lateral flow detection assay. Venous blood samples from positive participants and a randomly selected negative population were collected to confirm antibody titre, using two gold standard immunoassays, carried out independently by the Specialist Virology Centre, UHW. Results: 3.65% of the population tested positive for antibodies against COVID-19, with a higher prevalence seen in male participants (5% vs. 2.73% of females). In addition to gender, both pre-existing asthma and age were key determinants in antibody positivity. 78.26% retained antibodies at the 3 months follow up test. 36.36% of females lost antibody positivity between the 3 - and 6 - month time points compared with 8.3% of males. Lateral flow antibody testing was shown to have 96% sensitivity and 95% specificity compared with standard tests. Conclusion: We conclude that prevalence of COVID-19 antibodies is evident in the asymptomatic population, and in 78.26% of those initially antibody positive prevails at approximately 6 months from perceived time of exposure. Males are 4 times more likely to retain antibodies for longer than females.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. It mainly occurs in patients with chronic liver diseases such as cirrhosis caused by hepatitis B or C infections, as well as chronic alcoholics. HCC is one of the highly malignant neoplasms. Extrahepatic metastases are seen in 64% of patients with HCC, but metastases to the brain and skull are extremely rare. Here, the case of a 45-year-old male who presented with left III, IV, VI, IX, X, and XII cranial nerve palsies is reported. These were revealed to be caused by a distant metastasis from an unnoticed HCC with a background of previously undiagnosed chronic alcoholic liver disease. Physicians should be aware of the metastatic potential of HCC, in addition to its uncommon presentations, while encountering patients with an underlying liver disease. This case report demonstrates that metastatic HCC can lead to a rare, but possible, new onset of cranial neuropathy.

Indonesia merupakan negara troips yang memiliki jumlah penduduk yang banyak sehingga mengakibatkan banyak sekali bencana alam yang harus diterima oleh Indonesia. Penelitian ini difokuskan pada bencana banjir yang nantinya dapat dimanfaatkan untuk mengatasi bencana kekeringan dengan cara penampungan air hujan. Selanjutnya berdasarkan luas wilayah dan jumlah penduduk yang ada, jika kita bandingkan dengan bencana banjir yang terjadi maka provinsi Jawa Barat yang seharusnya dapat perhatian lebih besar karena luas wilayah untuk masing-masing penduduk paling kecil jika dibandingkan dengan provinsi yang lain. Penelitian ini yang dilakukan menggunakan algoritma SVM, C5.0 dan Naive Bayes yang digunakan untuk melakukan prediksi banjir untuk membantu pencegahan kebencanaan agar tidak tejadi korban yang lebih banyak. algoritma SVM dan C5.0 memiliki nilai akurasi yang sama yaitu sebesar 93.75% sedangkan algoritma Naive Bayes memiliki nilai akurasi sebesar 81,25. Sehingga dapat disimpulkan bahwa algoritma ini lebih akurat dan efisien untuk digunakan untuk melakukan prediksi. Sedangkan untuk waktu pemrosesannya maka algoritma Naive Bayes bisa dikatakan lebih cepat jika dibandingkan algoritma SVM dan juga algoritma C5.0.

Introduction: Spontaneous pneumomediastinum (PM) is a rare presentation associated with Coronavirus disease 2019 (COVID-19). Here, we report two cases presented with spontaneous PM associated with COVID-19 pneumonia.
Case Reports:
Case 1: A 58-year-old female patient was admitted to the Emergency Department (ED) with dyspnea, hoarseness, myalgia, and cough. A chest CT scan revealed subcutaneous emphysema, diffuse PM, bilateral diffuse areas of ground-glass opacity, and consolidations. The patient was transferred to the critical care unit. In critical intensive care, the patient developed multi-organ failure and expired on the 10th day.
Case 2: A 34-year-old male patient admitted to the ED with dyspnea and cough. A chest CT scan revealed diffuse PM, bilateral diffuse areas of ground-glass opacity, and consolidations. The patient was transferred to the critical care unit. His progress was uneventful and he was discharged after 12 days.
Conclusion: Patients suspected of PM should be examined closely during the differential diagnosis of chest pain, dyspnea, subcutaneous emphysema, and various lung- and heart-induced states. Patients diagnosed with spontaneous PM should be hospitalized for observation because the condition can be associated with complications, including death.

Bu araştırma böbrek nakli olmuş hastalarda depresyon, anksiyete, stres seviyeleri ile immünsupresif tedaviye uyum arasındaki ilişkiyi belirlemek amacı ile tanımlayıcı ve ilişki arayıcı türde yapıldı. Araştırma verileri 20 Kasım ile 10 Aralık 2021 tarihleri arasında toplandı. Araştırma sonunda 95 hastaya ulaşıldı. Verilerin analizi SPSS 25 programı kullanılarak yapıldı ve gerekli tüm yasal ve etik izinler alındı. Araştırma sonunda hastaların depresyon, anksiyete, stres, DASS-21 ve İTUÖ toplam puanları sırasıyla; 5.15±3.61, 5.16±3.78, 9.62±4.93, 19.94±10.37 ve 11.42±3.29 olarak belirlendi. Kadın hastaların depresyon puan ortalamalarının erkek hastalara göre daha yüksek olduğu tespit edildi. Serbest mesleği olan hastaların memur olarak çalışan hastalara göre daha yüksek bir depresyon puan ortalamasına sahip olduğu sonucuna ulaşıldı. Geniş aile yapısına sahip hastaların İTUÖ sıra ortalamalarının çekirdek aile yapısına sahip hastalara göre daha yüksek olduğu saptandı. Bu araştırmada hastaların İTUÖ puanları ile depresyon, anksiyete ve stres puanları arasında istatistiksel açıdan önemli bir ilişki tespit edilemedi. Böbrek nakli olmuş hastaların depresyon, anksiyete, stres seviyeleri ile immünsupresif tedaviye uyumları arasında ilişki bulunmadı. Daha büyük örneklem gruplarıyla benzer nitelikte araştırmalar yapılması önerilebilir.
