The present work is part of relational marketing, in particular consumer behavior in the field of service. Relationship marketing is based mainly on three pillars: quality, satisfaction, and loyalty. The choice of our conceptual model is based on an in-depth literature of previous studies, in view of the multiplicity of research work carried out in this field and the diversity of points of view of the researchers. The fundamental research question is: How to increase the level of customer satisfaction to retain them? The objective of this article is both to determine the explanatory dimensions of consumer satisfaction, but also to analyze their influence on overall consumer satisfaction. For this purpose, we have opted for the “FILTER” type attribute selection methods based on the “WEKA” programming environment. To this end, an empirical study was carried out. We employed quantitative methodology and data were analyzed by Structural Equation Models. The sample consisted of 242 customers of the airline “AIR ALGERIE”. The results obtained reveal to us what is hidden behind the overall customer satisfaction of this company. They also certify that the dimensions in question contribute differently to this satisfaction. Such results would help leaders to provide a double effort in order to bring real and effective improvements, but also to give more care to the relevant variables selected by the different methods applied. However, the results also revealed the importance of the service elements which contribute to overall customer satisfaction

Knowledge sharing has become an important part of organizations in increasing their competitiveness. However, the antecedent variable for the practice of knowledge sharing behavior is still very limited. This study aims to examine the influence of trust among organizational members and job involvement on the intensity of knowledge sharing behavior. The study involved 250 lecturers from various universities in the city of Malang, Indonesia. The research data were collected through a questionnaire and processed using SEM Partial Least Square. The results showed that trust among organizational members influenced job involvement and knowledge sharing practices. Furthermore, job involvement is proven to be a variable that mediates the effect of trust on knowledge sharing behavior.

НОВЕ ГЕНЕРАЦИЈЕ ДИРЕКТНОГ УБРИЗГАВАЊА
Authors: Милојковић Иван
Published: March 2021

У овом раду су описани системи директног убризгавања горива у радном простору мотора. Повећање ефикасности СУС мотора одувек је била тема константног истраживања и усавршавања ради максималног искоришћења термодинамичког потенцијала, како би се реални циклус приближио идеалном. Новим концептом директног убризгавања постигнуто је боље образовање, мешање, сагоревање и хлађење смеше услед целокупног убризгавања и испара­вања у комори сагоревања. Подложност детонантном сагоревању је смањена, услед чега је повећан степен сабијања. Ови и други фактори утичу да се у односу на конвенционалне системе убризгавања повећају излазни параметри мотора (снага и момент), док је потрошња горива и емисија издувних гасова смањена. Слојевита смеша карактеристична за ове моторе се формира на три начина вођења пуњења: зидом, ваздухом и млазом.

Siła filozofii, filozofia siły
Authors: Majcherek Janusz
Published: March 2021

The power of philosophy, philosophy of power: Selfless search for truth does not only make sense of philosophy and science, but also involves participating in a competition between rival theories and hypotheses. Truth is not an ultimate criterion in this process, especially after Michel Foucault revealed its inclinations towards violence. Questioning the position of truth opens the door to different criteria, among them — power. Using the argument of power in philosophical disputes and scientific controversies has a long tradition and nowadays with the unprecedented development of technology it has been offered new tools.
Between the ethics of forgiveness and the unforgivable: Reflections on Arendt’s idea of reconciliation in politics
Authors: Wonicki Rafał
Published: March 2021

The aim of the article is to examine the role that memory and oblivion, forgiveness and unforgiveness play in Hannah Arendt’s thought in relation to acts of violence in the political sphere. Political communities do not always decide to remember the crimes they have committed or the wrongs they have suffered, but neither can they always forget their mutual harms, even when there is already peace between them. Without striving to exhaust the entire subject matter of Arendt’s work, I would like to illustrate the difficulty of understanding the role forgiveness plays in her thought as well as to indicate possible solutions when forgiveness becomes unachievable within the framework of her considerations. Her reflection can be divided into two stages. The first is a focus on the idea of radical evil and the need to forgive perpetrators for their crimes. Second, under the influence of the Adolf Eichmann trial, she developed the idea of the banality of evil. This idea points to situations so terrible that they transcend all human moral judgment, making forgiveness impossible. However, even when the moral possibility of individual forgiveness has been rejected, when the legal possibility of seeking justice has been exhausted and when victims and perpetrators in the community are still unable to live together peacefully, Arendt’s thought leads us to the possibility of political reconciliation.

BIOTERRORISM: THE DEVELOPMENT AND ITS REGULATIONS ACCORDING TO THE INTERNATIONAL LAW
Authors: Elyasa Yaksa
Published: March 2021

The biological weapon used as a terrorism facility (bioterrorism) could endanger the lives of mankind. Besides its purpose of mass destruction, this weapon has been banned from being used towards the human. Bioterrorism threat at least had occurred in more than 30 countries across the globe. In the 14th century, bioterror incidents recorded in black death plagues in Europe caused more than 50 million deaths and vanished more than 60% of its population back then. Because of the bioweapon impacts, there are concerns if this weapon is under irresponsible parties such as the group of terrorists. Several regulations on the prohibition of biological weapons have been made, such as the Production and Stockpiling of Bacteriological [Biological] and Toxin Weapons and Their Destruction 1972 (Biological Weapon Convention 1972). However, it seems that they have not solved using biological weapons as a means of terrorism. The purpose of this paper is to find out how international law arrangements regarding bioterrorism. This research used normative legal research with secondary data sources and literature study techniques.

О МЕТОДЕ ИЗВЛЕЧЕНИЯ КЛАССИФИКАЦИОННЫХ ПРИЗНАКОВ СЕТЕВЫХ ТРАФИКОВ НА ОСНОВЕ АНАЛИЗА СИГНАЛОВ
Authors:   Институт Информационных Технологий НАНА, Шыхалиев Рамиз
Published: March 2021

Современные сетевые трафики имеют множество признаков и динамических свойств, которые отражают поведение сети и активность пользователей. Признаки сетевых трафиков играют важную роль в их классификации. Однако традиционно используемые признаки не отражают сложный нелинейный характер сетевых трафиков и не обеспечивают высокую точность классификации. Известно, что сетевые трафики имеют нестационарный характер и нелинейные динамические характеристики, такие, как самоподобия, мультифрактальность, долговременная зависимость и периодичность. Поэтому очень актуально извлечение новых робастных классификационных признаков, которые повысят точность классификации сетевых трафиков. Для решения этой проблемы наиболее перспективным методом является спектральный анализ сигналов сетевых трафиков. В работе для спектрального анализа сигналов сетевых трафиков предлагается использовать вейвлет-преобразование, через которое можно определить энергетические характеристики сигналов сетевых трафиков, используемых в качестве классификационных признаков.

Invertible quantum operations and perfect encryption of quantum states
Authors: Nayak A. , Sen P.
Published: March 2021

In this note, we characterize the form of an invertible quantum operation, i.e., a completely positive trace preserving linear transformation (a CPTP map) whose inverse is also a CPTP map. The precise form of such maps becomes important in contexts such as self-testing and encryption. We show that these maps correspond to applying a unitary transformation to the state along with an ancilla initialized to a fixed state, which may be mixed. The characterization of invertible quantum operations implies that one-way schemes for encrypting quantum states using a classical key may be slightly more general than the "private quantum channels'' studied by Ambainis, Mosca, Tapp and de Wolf {AmbainisMTW00}. Nonetheless, we show that their results, most notably a lower bound of 2n bits of key to encrypt n quantum bits, extend in a straightforward manner to the general case.
How to build a 300 bit, 1 Giga-operation quantum computer
Authors: Steane A.M.
Published: March 2021

Experimental methods for laser control of trapped ions have reached sufficient maturity that it is possible to set out in detail a design for a large quantum computer based on such methods, without any major omissions or uncertainties. The main features of such a design are given, with a view to identifying areas for study. The machine is based on 13000 ions moved via 20$\mu$m vacuum channels around a chip containing 160000 electrodes and associated classical control circuits; 1000 laser beam pairs are used to manipulate the hyperfine states of the ions and drive fluorescence for readout. The computer could run a quantum algorithm requiring $10^9$ logical operations on 300 logical qubits, with a physical gate rate of 1 MHz and a logical gate rate of 8 kHz, using methods for quantum gates that have already been experimentally implemented. Routes for faster operation are discussed.
Continuous-discrete entanglement: an example with non-relativistic particles
Authors: Harshman N.L.
Published: March 2021

This article discusses entanglement between two subsystems, one with discrete degrees of freedom and the other with continuous degrees of freedom. The overlap integral between continuous variable wave functions emerges as an important parameter to characterize this kind entanglement. ``Beam-like'' entanglement and ``shape-like'' entanglement are contrasted. One example of this kind of entanglement is between between the spin degrees of freedom and the momentum degrees of freedom for a non-relativistic particle. This intraparticle entanglement is Galilean invariant.
Mutually unbiased bases and orthogonal decompositions of Lie algebras
Authors: Boykin P.O. , Sitharam M. , Tiep P.H. , Wocjan P.
Published: March 2021

We establish a connection between the problem of constructing maximal collections of mutually unbiased bases (MUBs) and an open problem in the theory of Lie algebras. More precisely, we show that a collection of $\mu$ MUBs in $\K^n$ gives rise to a collection of $\mu$ Cartan subalgebras of the special linear Lie algebra $sl_n(\K)$ that are pairwise orthogonal with respect to the Killing form, where $\K=\R$ or $\K=\C$. In particular, a complete collection of MUBs in $\C^n$ gives rise to a so-called orthogonal decomposition (OD) of $sl_n(\C)$. The converse holds if the Cartan subalgebras in the OD are also $\dag$-closed, i.e., closed under the adjoint operation. In this case, the Cartan subalgebras have unitary bases, and the above correspondence becomes equivalent to a result of \cite{bbrv02} relating collections of MUBs to collections of maximal commuting classes of unitary error bases, i.e., orthogonal unitary matrices. This connection implies that for $n\le 5$ an essentially unique complete collection of MUBs exists. We define \emph{monomial MUBs}, a class of which all known MUB constructions are members, and use the above connection to show that for $n=6$ there are at most three monomial MUBs.
Assessing in Silico Models and Methods for Non-Covalent Interactions between Graphene and Small Molecules
Authors: Ehlert Christopher , Piras Anna , Gryn'ova Ganna
Published: March 2021

Designing and optimising graphene-based gas sensors, which involve physisorption of analytes on the sensor surface, requires theoretical insights into the strength and nature of such non-covalent interactions. This modelling entails constructing appropriate atomistic representations for an infinite graphene sheet and its complex with the analyte, then selecting accurate yet affordable methods for geometry optimisations and energy computations. In this work, density functionals from the 2nd to 5th rungs of Jacob’s ladder, coupled cluster theory, and symmetry-adapted perturbation theory in conjunction with a range of surface models, from benzene to the periodic system, were tested for their ability to reproduce experimental adsorption energies of CO2 on graphene in a low-coverage regime. The best agreement with the reference computations was found for global and double hybrid density functionals, while experimental adsorption energies were reproduced within chemical accuracy by extrapolating the SAPT0//DSD-BLYP-D3 interaction energies from finite clusters to infinity. This simple yet powerful extrapolation scheme effectively removes size dependence from the data obtained using finite cluster models, and the latter can be treated at more sophisticated levels of theory relative to periodic systems.
Estimation of Total and Lipid Bound Sialic acid in oral leukoplakia and oral squamous cell carcinoma patients
Authors: Archana Sonone  , Alka Hande  , Madhuri Gawande  , Swati Patil
Published: March 2021

Tumour markers are biochemical substances released through tumour cells. They are considered as the rationale or consequence of the carcinogenesis process.  Neoplasms often have an increased concentration of sialic acid on the tumour cell surface and are shed or secreted by some of these cells, which increase the concentration in blood.  To determine serum levels of total sialic acid (TSA), lipid-bound sialic acid (LBSA), in patients of oral Leukoplakia (LP) and oral squamous cell carcinoma (OSCC). The study comprises 75 subjects which include 25 cases of LP, 25 cases of OSCC and 25 cases of healthy individuals as control. 10 ml intravenous blood was collected under aseptic condition, and biochemical analysis of total sialic acid and lipid-bound sialic acid was carried out by spectrophotometer. We observed levels of TSA and LBSA significantly increased in LP and OSCC as compared to a healthy control group. The increased level of TSA and LBSA in LP helps to determine the early stage of the disease. Further differentiation in grades of OSCC is also possible by these biochemical markers. Thus serum levels of TAS, LBSA can be used as diagnostic and prognostic markers.

Published: March 2021

Medication-related hospital admissions have gained attention during the last few decades. It has been reported that up to 5% of all hospital admissions were medication-related and 50 % of those were avoidable. In India, studies on medication-related hospital admissions are still in the infancy stage. The objective of the study was to assess the types and outcomes of medication-related hospital admissions (MRHA) in a tertiary care teaching hospital. This prospective observational study was conducted for six months at JSS Hospital, Mysuru. Patients of any age and gender, who were admitted to General Medicine, Emergency, Nephrology, Psychiatry, Pulmonology wards due to medication-related problems were enrolled in the study after obtaining an Inform Consent Form. All the necessary data about MRPs were collected and documented in a suitably designed data collection form. MRPs were classified by using Hepler and Strand classification, and the implicated drugs were coded by using the Anatomical Therapeutic Chemical Classification system (ATC) code. Prevalence of medication-related admissions was calculated by dividing the total number of medication-related admissions and the total number of admissions to the hospital. There were 185 MRHA during the study period in the respective departments. The total prevalence of MRHA in the included departments was 1.27%. Failure to receive drugs (50.27%) accounted for the maximum MRHA, followed by adverse drug reactions (46.44 %) and overdose (3.27%). The average cost associated with MRHA was found as INR 10,440 (USD-174, £ - 149). The average length of stay of MRHA was found as approximately seven days [6.96, (sd±2.42)]. The study shows that failure to receive drugs leading to hospitalization are frequent and constitute a significant economic burden. Training of patients and prescribers may lead to a reduction in hospitalization due to MRPs and thus lessen their financial burden.

Authors: Volga Harikrishnan  , Naveen Kumar M
Published: March 2021

Dengue fever is the most common arboviral infection in the world, and it is a disease with a broad clinical spectrum and a wide variety of presentations, ranging from asymptomatic to an undifferentiated fever (viral syndrome) to the more severe forms such as severe dengue (SD) or Dengue hemorrhagic fever (DHF). The diagnosis of dengue fever is carried out based on clinical, epidemiological and laboratory data. Among laboratory tests, both non-specific [blood count, platelet count, tourniquet test, prothrombin time (PT), activated partial thromboplastin time (APTT), liver function tests and serum albumin concentration] and specific tests (viral isolation tests and serology for antibody examination) are used. The principle aim of our study is to assess and compare the biochemical and haematological parameters of patients with dengue. In our study population, the peak frequency of the patients who were dengue positive was on the age group between 21 and 30 years (44%), and it was more common among males. The most common serological indicator of dengue fever was the presence of NS1 antibody. High haematocrit (56%) was found in most of the patients, and the next common finding was thrombocytopenia (51%). Elevated Serum glutamic oxaloacetic transaminase seen in 53% of cases and Elevated Serum glutamic pyruvic transaminase, Alkaline Phosphatase, Serum Bilirubin, Serum creatinine and Serum urea were found in 41%, 11%,7%, 4%, 3%of cases respectively. The knowledge about these parameters helps the clinician in early diagnosis of the cases and initiation of the management measures before the drastic clinical features of the disease sets.

Authors: Bangunawati Rahajeng  , Sabtanti Harimurti
Published: March 2021

Carbamazepine is often used for indications other than epilepsy. In Indonesia, carbamazepine is registered for prophylaxis for lithium-responsive manic depressive disease, antiepilepsy, epilepsy of all types (except petit mal), and trigeminal neuralgia. This research aimed to describe the use of carbamazepine at PKU Muhammadiyah Hospital Yogyakarta. This was an observational study with a cross-sectional design. The data were taken retrospectively from the medical records of patients who received carbamazepine during 2014. The use of carbamazepine included 494 prescriptions given to 117 patients. The physician who most prescribed carbamazepine was a neurologist (63.04%). The most appropriate use of carbamazepine following the National Agency for Drugs And Foods Controls of Republic of Indonesia (NA-DFC) was for epilepsy (34.19%), followed by trigeminal neuralgia (6.84%) and bipolar disorder (4.27%). The most off-label use was in cases of stroke (7.69%), followed by diabetic neuropathic pain, herniated nucleus pulposus, and cephalgia (all 3.42%). Evidence found for the off-label use of carbamazepine was in diabetic neuropathic pain and neuropathic pain post-stroke (24.53%). The use of carbamazepine at PKU Muhammadiyah Yogyakarta hospital is mostly on-label, with some off-label use. The off-label use of carbamazepine (24.53%) has strong evidence, while some use has a lack of scientific support or no evidence at all.

Threshold Pump Power And Stability Zone Study of A Cw Ti:sa Laser Based on Using Two Different Dielectric Broadband High Reflective Cavity Mirrors
Authors: Adil Kareem Awaz , A. S. Sadiq Mayi Diyar
Published: March 2021

The present work study the optical parameters for CW operation in Ti:Sapphire laser system with the focus on stability zone and threshold pump power. The main aim of this study is to explore the influence of a broadband dielectric resonator mirrors used in the laser cavity on the stability zone and threshold pump power. This effect has been determined by using two types of mirrors with different broadband reflection. The experimental results show the dependence of the stability and laser threshold pump on broadband dielectric mirrors. For a broader dielectric mirror, the stability zone shows larger stable distance with respect to the narrower mirror. Moreover, the threshold pump for the broader band is smaller than the narrower. This study allows researcher choosing the appropriate optical components for generating more stable laser with small threshold pump power.

Published: March 2021

Erectile dysfunction is currently a growing health concern and one of the most prevalent sexual dysfunctions in men worldwide. Diabetes mellitus is considered a risk factor for developing ED. Therefore, this SHIM study was designed to assess the prevalence, severity and determinant of erectile dysfunction in type II diabetes mellitus patients and healthy men. This hospital-based cross-sectional study was conducted on 132 diabetic male patients and 66 healthy men at the Nkenkaasu hospital, Offinso North, Ghana between January-June, 2019. A pre-structured questionnaire and patients’ medical records were used to document relevant information. Erectile function was assessed using Sexual health inventory for men questionnaire. Data were analyzed using SPSS version 22.0. Chi-square test, binary and multivariable logistic regression analysis were used appropriately. The mean age of study participants was 57.94 ± 9.79 years. The overall mean score on the SHIM test was 12.42 ± 8.15 (range: 1–25), mean of 9.59±7.83 for the type II diabetics and 18.08±5.39 for non-diabetic men. The total erectile dysfunction (ED) prevalence was 81.8% (95% CI: 0.757, 0.869). ED was common in diabetics (70.4%) compared with healthy men (29.6%). Severe ED was 93.7% and 6.3% in the diabetic and non-diabetic men respectively. Multivariate logistic regression revealed that diabetic men with poor health-related quality of life had 3.48 times likelihood of having ED compared to their non-diabetic counterparts (AOR= 3.48, 95% CI; 1.284, 9.453). Very high erectile dysfunction was observed in our study participants. This is worrisome owing to the profound negative impact of ED on the quality of life and fertility of men. It is recommended that periodic assessment of erectile function should form part of routine diabetes care, focusing attention on the modifiable risk factors in preventing, delaying progression, or reversing established ED in persons. Doi: 10.28991/SciMedJ-2021-0301-4 Full Text: PDF

Authors: Ghosh Suman , TVSVGK Tilak , Somasundaram Venkatesan , Deepti Mutreja
Published: March 2021

Oncological emergencies present in a multitude of manners-structural, metabolic, hematologic, etc. affecting multiple systems, often. Urgent institution of therapy is often required for a successful outcome. Occasionally, the treatment of one emergency can initiate a related or unrelated emergency, necessitating management of all the complications simultaneously. Superior vena cava obstruction (SVCO) is a medical emergency and most often manifests in patients with a malignant disease process requiring immediate diagnostic evaluation and therapy due to its’ life threatening presentation. The management of the SVCO is usually with chemotherapy, radiotherapy or intervention. In cases of large tumor burden, management of SVCO can trigger other complications. Tumor lysis syndrome is an oncologic emergency, which is characterized by a massive release of intracellular potassium, phosphate, and nucleic acid metabolites into the systemic circulation, which can be life-threatening. We present the case of a T-cell acute lymphoblastic leukemia with superior vena cava syndrome, developing tumor lysis syndrome on instituting definitive chemotherapy in a young patient. Doi: 10.28991/SciMedJ-2021-0301-6 Full Text: PDF
Florence Nightingale’s Nursing and Health Care: The Worldwide Legacy, As Seen on the Bicentenary of Her Birth
Authors: McDonald Lynn
Published: March 2021

Aim: The aim of this article is to articulate the distinctive features on the Nightingale School of Nursing on the occasion of the 2020 bicentenary of her birth. Design: This is a historical study, based on all the available printed and archival sources of Nightingale’s writing. Methods: The article draws on Nightingale sources (full books, articles, chapters, pamphlets and unpublished letters in more than 200 libraries and archives worldwide) published in The Collected Works of Florence Nightingale, 16 volumes, peer-reviewed; transcriptions are available on its website [1]. Results: Nine key findings are discussed in the article: (1) how different Nightingale’s nursing was from what was called ‘nursing’ at the time; (2) that the central role of training allowed nursing to move from being a women’s profession to being open to all qualified; (3) the evolution of Nightingale nursing as medical science and public health advanced; (4) the academic content in her training; (5) team building in her system; (6) her (often misrepresented) views on germ theory; (7) her late work on preventing cholera; (8) the worldwide influence of her work; (9) her work upgrading workhouse infirmaries and advocacy of what would be later called universal access to health care. Conclusion: Nightingale’s ongoing relevance is evident in many of today’s concerns, such as lack of access to quality health care; the shortage of nurses in the United Kingdom’s National Health Service (and in some other countries) and inadequate wages and salaries of nurses and nurse practitioners; the ongoing dangers in nursing and the need to give nurses a safe working environment (the coronavirus is an extreme example); and inadequate data for health care planning purposes. Doi: 10.28991/SciMedJ-2021-0301-7 Full Text: PDF
Homer’s fi xed epithets golden and silver
Authors: Malinauskiene N.
Published: March 2021

This article provides a comprehensive linguistic analysis of the Homeric epithets golden and silver in comparative terms. They are considered in the following aspects: frequency of use, semantic structure, contextual environment, word-formation features and capabilities, stylistic originality and aesthetic signifi cance, as well as translation options into Russian. The quantitative (higher usage statistics) and qualitative (more complex semantic structure, richer word-formation capabilities and lexical compatibility) predominance of golden over silver, its greater social and aesthetic value is established. As a result of the research, the degree of traditionality of these epithets and the tendency to a variety of their use are clarifi ed. There is also a general desire of translators to preserve the tradition and constancy of these epithets with the assumption of only some variation. The problem of the infl uence of the Homeric use of these epithets on the further literary tradition is raised due to the fact that the basis for ideas about the Golden age was already laid in the Homeric era.

Внаслідок інтенсивного антропогенного навантаження на басейни річок спостерігається поступове погіршення їх якісного стану. Особливо вразливого впливу зазнають малі річки. Відслідковується зниження показників, які характеризують склад і властивості води, а також її придатність для конкретних цілей використання. У зв’язку з цим вирішення проблем якісного стану водних об’єктів є актуальним. Дослідження базується на визначенні за певними ознаками класів і категорій якості води згідно з «Методикою екологічної оцінки якості поверхневих вод за відповідними категоріями». У роботі здійснено екологічну оцінку стану поверхневих вод р. Пруднік вище та нижче очисних споруд міста Рожище за період 2014–2019 рр. Виконано структурування основних статистичних характеристик для досліджуваних хімічних показників води у створах. Проаналізовано динаміку фізико-хімічних показників русла річки. Проведено порівняльний аналіз концентрацій компонентів сольового складу води у затверджених створах. Визначено та досліджено вплив природних та антропогенних чинників на формування хімічного складу і якості поверхневих вод. Згідно з отриманими результатами дослідження найбільші перевищення нормативних значень ГДК для рибогосподарських водойм зафіксовані за вмістом розчиненого кисню, БСК5, ХСК, амонію сольового та нітритів, азоту нітритів, азоту амонійного, азоту загального, фосфатів, заліза загального. Відповідно до коефіцієнту забруднення р. Пруднік належить до «слабо забрудненої». За показниками комплексного екологічного індексу стан р.
