Published: June 2021

The problem of road safety does not lose its relevance in our time. The condition and performance of tires has a significant impact on the safety of road transport. Unfortunately, the tire pressure monitoring requirements of the developers are not always met. Naturally, now some modern cars are equipped with various systems for monitoring and even adjusting the internal tire pressure. However, there are relatively short periods of time during which the pressure and temperature in the tire change dramatically, and hence its other performance and properties. First of all, we are talking about dramatically changing weather conditions and the starting movement of the car. And then additional monitoring of tire pressure is needed. Goal. On the basis of the experimental studies carried out, to obtain the dependence of the temperature and pressure changes inside the tire on the time of car movement. To determine the initial period of time of car movement until the pressure and temperature in the tested tires stabilize. Methodology. The work used the technique of both bench tests of tires in the laboratory and road tests under real weather conditions by car. Based on the numerical processing of the experimental results, dependencies were obtained, using which it is possible to determine the increase in temperature and pressure in tires in the mode of starting movement of the car. Results. The analysis of scientific publications on this topic is performed. The time from the beginning of the car to the stabilization of temperature and internal pressure in the tires is determined, as well as the increase in temperature and pressure inside the tire during this period. The method of determining the starting time of the car to stabilize the internal pressure and temperature is proposed. Originality. In this work, for the first time, a method is proposed for assessing the temperature and internal pressure in tires in the mode of starting movement of the car, which makes it possible to obtain dependencies without resorting to further experimental studies. Practical value. Using the obtained dependencies for certain tires and under different weather conditions, it is possible to predict the change in tire pressure at the starting mode of the car's movement, and therefore make adjustments to this value, if necessary, which will have a positive effect on the safety of moving vehicles.

Problem. Currently, there is no universal approach to improve the efficiency of the urban public transport operation. Different methods are used during the estimation of public transport operation cost and the quality of services for the passengers. It makes actual the development of the target function which will allow assessing the carrier cost and passenger expenditures, and therefore find the balance between the interests of these parties of the transportation process. Thus, the alternative to the existing approaches can be created and then used to organize passenger transportation and improve transport enterprise management. Development of this alternative is the actual task as the new target function will open the horizon to improve the methods of organization of public transport operation. Goal. The new approach to optimize the costs of public transport operation needs to be tested for the appropriateness for the planning of passenger service in cities. Methodology. The developed target function was derived as the result of the analysis of the economic and social factors influencing the efficiency of the urban public transport operation. Results. The use of the developed target function allows finding the optimal values of cost components for the passenger and the carrier. Originality. The obtained function to optimize the performance of public transport allows reducing the costs of suboptimal use of vehicles capacity, suboptimal allocation of the vehicles to the routes and the irrational organization of vehicles operating on the routes. Practical value. The results of the research clarify the controlled and uncontrolled parameters of the public transport system operation.

Authors: Pant Amba Datt 
Published: June 2021

In muon spin rotation and relaxation (mSR) method, theoretical work using first-principles calculations helps to understand the stopping sites and charge states of muon in the sample materials. To support the mSR measurement on protein and DNA, a systematic first-principles study starting from the constituents of the protein has been performed. In this work, the behavior of muonium (Mu = m+e-, bound state of a muon and an electron which is like a light isotope of H atom with similar chemical properties) in a N-acetylglycine-N-methylamide (AGMA), a part of peptide bond, is presented. It is found that the stopping site of Mu is around O of unsaturated bonds between C and O in the AGMA. Further calculations towards whole protein and DNA will be performed to support mSR studies.

Introduction: Nepal started the first phase of COVID-19 vaccination for frontline healthcare workers in January 2021 with the ChAdOx1 nCoV-19 (COVISHIELD) vaccine. We conducted active surveillance of Adverse Effect Following Immunization (AEFI) after the first dose of the vaccine administered at one of the sentinel sites for vaccination, Patan Academy of Health Sciences (PAHS).
Method: All the 5591 first dose ‘COVISHIELD’ vaccine recipients between 27 Jan -5 Feb 2021 at PAHS, were approached through phone calls to collect data on AEFI. Incidence of common AEFIs in different age groups, gender and those with previous history of COVID-19 were analyzed. Presence of any Adverse Events of Special Interest (AESI) were evaluated.
Result: Out of 5591 vaccines recipient, 3991 (71.3%) responded to the phone call and AEFI was noted in 3394 (85.04%) of them. Minor AEFI was seen in 3391 (84.9%), severe Minor AEFI in 1 (0.02%) and Serious AEFI in 2 (0.05%). Out of 807 vaccine recipients with previous history of COVID-19, 709 (87.9%) had AEFI while of the 3184 with no past history of COVID-19, 2685 (84.3%) had AEFI. However, some of the systemic AEFIs were noted more frequently in those with past COVID-19 infection. A total of 1886 (55.6%) took self-medication for symptom relief, 278 (8.2%) took leave from work while 26 (0.76%) visited health facility for the AEFIs.
Conclusion: Most AEFIs following the first dose of COVISHIELD vaccine were mild and resolved within a few days. Except for one case of anaphylaxis, no other AESI were encountered.
The ‘Vero Cell’ COVID-19 vaccine rollout in Nepal: What we know about the Chinese vaccine development and access?
Authors: Shah Jay Narayan 
Published: June 2021

The world has changed dramatically from the impact of the COVID-19. It has impacted the normality of daily life, highlighting the failure of rich and poor nations alike, which is evident from the high number of human lives lost in rich and powerful countries like the USA with total deaths of 32,735,704 and Europe with 43,708,958 until April 24, 2021, as per Worldometer. The COVID-19 pandemic has shown that all of us ‘have and have-not’, no one can escape from the effects of the lockdowns, disruption of normal life including education, businesses, etc. reminding all of us that equitable access to vaccines is the best possible choice not to further exacerbate the challenges because ‘no country is safe until every country is safe’. It is a remarkable scientific achievement that within a year of the identification of the virus, we have COVID-19 vaccines, albeit available mostly in rich countries. The benefit of research is possible only with solidarity, by sharing the available resources, vaccine included, for the control of the ongoing COVID-19 pandemic.
Modern science and technology, including the development and marketing of COVID-19 vaccines, have been focused in the USA and Europe. China joined this club of elites of science following the Chinese FDA approval of Sinopharm (the subsidiary of state-owned China National Pharmaceutical Group- CNPG), first COVID-19 vaccine (inactivated Sars-Cov-2) based on the results of the phase-3 clinical trial in UAE and Bahrain showing up to 86% efficacy of the vaccine in preventing COVID-19.
Detail of trials of Sinopharm inactivated COVID-19 vaccines (Vero Cells) available on two early trials in China (Phase I/II ChiCTR2000031809, enrollment 1,456) and later 4 trials outside China (phase III, NCT04510207 Bahrain, Egypt, Jordan, United Arab Emirates- enrollment of 45,000; ChiCTR2000034780 United Arab Emirates, enrollment of 15,000; NCT04612972 Peru, enrollment of 6,000) show the progress of research and approval in China and UAE.

Introduction: Spontaneous abortion (SA) is one of the adverse outcomes during pregnancy, which is a challenge for maternal well-being. The present study aimed to analyze the predictors of SA among reproductive age women.
Method: A hospital-based case-control study was conducted at Patan hospital, Nepal. The consecutive sampling technique was used to select the cases (84) and a purposive sampling technique was used for controls (168) in a 1:2 ratio. Ethical approval was obtained. Data were collected through face to face interviews using a structured questionnaire. Descriptive and inferential statistics (Chi-square, Fisher exact test, and logistic regression) were used for analyzing the data.
Result: We found that previous history of abortion (OR=3.80, 95% CI=1.8-7.70), heavy lifting (OR=20.45, 95% CI =4.48-93.38), emotional disturbance (OR=10.06, 95% CI=1.06-96.96), health problems (fever of unknown cause and urinary tract infection) during pregnancy (OR=16.53, 95% CI=1.90-143.41), coffee intake (OR=0.36, 95% CI=0.20-0.63), unplanned pregnancy (OR=0.10,95% CI=0.04-0.22), preconception counseling/care not received (OR=6.48, 95% CI=2.18-19.21) were the significant predictors of SA among reproductive age women.
Conclusion: Our findings show that the previous history of abortion, heavy lifting, emotional disturbances, health problems, and coffee intake during pregnancy are the significant cause of SA; and preconception counseling and planned pregnancy are protective factors.

The role of a garantor in the quality assurence processes at the stage of educational program formation
Authors: Butenko Andrii , Yeremenko Olena 
Published: June 2021

The article explores specific aspects of involving the guarantor of the educational program in its formation. The urgency is due to intensive changes in the quality assurance system of higher education, which require performing related new functions by research and teaching staff. That is why the National Agency for Quality Assurance in Higher Education has proposed a separate functional – the guarantor of the educational program – who coordinates the design, updating and implementation of the educational program. Correct involvement of the guarantor at the stage of the educational program formation will help to avoid the shortcomings caused by violation of logic and the formal attitude to the maintenance of educational programs.
A survey of educational program guarantors was developed and conducted, thanks to which it was established that the vast majority of them were deliberately involved at all major stages of the educational program formation. It is rather positive that even at the stage of initiation, which is primarily the preference of collective and / or administrative bodies of higher education institutions, guarantors are informed about the possibility of opening an educational program. Guarantors are actively involved in studying the experience of foreign and Ukrainian educational programs, primarily determining which of them deserve attention. However, it should be emphasized that both in the development of best practices and in the development of the curriculum as part of the educational program guarantors recognize the most important parameter of educational components that is logical, because it is based on the educational process implementation.
It can be stated that the lack of sufficient practical experience, the process of accumulation and analysis of pros and cons in the educational process formation, which is still ongoing, currently do not allow to draw an unambiguous conclusion about the conclusive creation and certainty of the guarantor’s functionality. Therefore, it is important, on the one hand, to conduct further research and outreach on the guarantor’s functionality and participation in the educational program formation, and on the other – to promote the development and improvement of the local regulatory framework of higher education institutions on this issue.

Published: June 2021

In the world of education there is already a curriculum that must be carried out with learning outcomes that must be achieved by students, as well as lecturers who also have duties as facilitators in these achievements. With the Learning Outcomes, it makes students have the ability or competence in accordance with the requirements to meet the predefined study program profiles. One of the competencies that graduates of the Broadband Multimedia field must achieve is in the field of data processing including data compression. The most widely used data compression technique is the Huffman code. Some research on the Huffman code has been done a lot, and someone has made the Calculator application. The calculator is used to determine the code for each character. The code for each character is not fixed, depending on the frequency of appearance in a text. The more often the character appears, the shorter the code. In this study, it has proven that the feasibility of the Huffman Calculator as a tool for Learning Outcomes can be done where data compression with language variables, in this case English and Bahasa Indonesia to the compression ratio, produces the same compression ratio, which ranges from 1.51 to 1.64 for Bahasa Indonesia while English is 1.56 to 1.83, with the average entropy for English 4.35 and Bahasa Indonesia 4.41.

Keywords: competence , data compression, huffman code, learning outcomes.

Authors: Rafsyam Yenniwarti , Dewanti Alica , Nurjihan Shita Fitria 
Published: June 2021

Long Term Evolution (LTE) is 4th generation (4G) technology that used as cellular technology. LTE works in various bands, one of band is 1800 MHz. At each location, the signal level that will received by the user varies depending on the usage location. At indoor location, signal level will weaken due to passing the obstacle like trees or walls, so the signal level that the user receivers is less than the maximum. To improve this condition, a repeater is needed. A repeater need an antenna as a signal receiver that transmitted from eNodeB and an antenna for transmitting a signal that has been amplified. In this paper will be explained about design an antenna microstrip double triangular patch with slot Y as an indoor antenna that used for transmitting a signal that works at frequency 1800 MHz. Micostrip antenna that was fabricated and tested has specification value is obtained which are return loss = - 20,702 dB, VSWR = 1,1566, gain = 6,9 dB, and the radiation pattern is unidirectional. Signal level antenna testing is performed on three location by using four provider. The highest signal level gained by Telkomsel provider that is -77 dBm and the lowest is XL provider that is -100,6 dBm.
