Collaboration in Handling COVID-19 Turbulence from a Threefold Perspective: A Literature Review
Authors: Pasaribu Andy , Kurniawan Teguh
Published: October 2022

The crisis due to COVID-19 can be called turbulence and its handling requires cross-border collaboration because complex problems tend to be overcome through multi-actor collaboration in networks and relationships to obtain common solutions. Collaborative governance is present as an instrument for implementing policies for handling COVID-19 to address the government's limitations in material, technical, and resource matters. Using a qualitative approach, this study aims to identify the implementation of collaborative governance in handling COVID-19 by countries in the world in a threefold perspective. This perspective is a new approach in collaborative governance that has the same basis as the Collaborative Governance Regime theory, but tends to narrow the thinking to three layers that support each other in the form of folds: values ​​(individuals and policies), decision structures (action situations and sub-systems). policy), and context (external variables, stable parameters, and external events). Public values ​​grow from the social context and are articulated in collaborative governance platforms and are important for the government to work on to improve community compliance with government programs. The turbulent COVID-19 situation creates space and decision-making. Each country has different choices, backgrounds, and policies but still bases the process of making and implementing policies on collaborative governance according to their respective preferences. In the folds of policy style and administrative culture, each country has its own dynamics. Countries with sufficient experience in handling outbreaks are able to make administrative adjustments more quickly, which helps speed up the response to the pandemic

The Covid-19 pandemic has affected many aspects, including public health services. In this situation, the role of the government is needed to continue to strive to fulfill and ensure that health services continue to run well. This study aims to determine the government's response at the beginning of the pandemic phase and to find the inhibiting factors in fulfilling public health services in Makassar. This study also makes it possible to see how the prospects for public health services after the pandemic will be in the future. This study uses documentation data and internet data to collect relevant information. Data analysis uses a qualitative approach by maximizing the use of the Nvivo 12 Plus analysis software. The findings of this study indicate that during the COVID-19 pandemic period, public health services do not only focus on infected patients but also public health services as a whole. This causes services to be less than optimal because medical personnel and infrastructure cannot accommodate the situation. In this situation, aspects still hinder the fulfillment of public health services, including low public awareness, access to information, regulations, and the fulfillment of health facilities. The prospect of health services becomes essential in the future. This requires a more innovative and adaptive national health system.

Published: October 2022

Digital platforms are tools of great importance for the evaluation of tourist destinations, as they allow tourists to access photos, evaluations and tips from users who have enjoyed destinations and attractions visited, thus being a source of consultation for other people who plan their trips. In this research, the analysis of comments on the TripAdvisor website was developed, aiming at mapping important attributes, in the visitors’ point of view, from a qualitative approach, guided by principles of netnography in the city of Paranaguá/PR, Brazil. The period considered as the basis for the analysis extended between January 2018 and January 2020 in order to reflect the realistic perceptions of the normality experienced by visitors in relation to the attractions without the bias of the Covid 19 pandemic time. In order to determine the corpus analyzed in the present study, the attractions available in the “Essential in Paranaguá” option were considered, classified by TripAdvisor as “places to see; ways to explore and; typical experiences”. Data collection was performed manually, with a copy of each comment left on the platform being made to a text document. 112 comments were compiled into a single text document with 16 pages and 6258 words, which form the textual corpus. This corpus was analyzed using the free software Iramuteq, suitable for qualitative and quantitative analysis of texts, such as correspondence analysis, hierarchical classifications, similarity analysis and word clouds. This set of possibilities enabled a better understanding of the meanings, motivations and perceptions emanating from the texts that make up the interactions of users of the TripAdvisor website in relation to the attractions of the city. Preliminary analyzes reveal that ‘Ilha do Mel’ and ‘Ilha dos Valadares’ are the most prominent attractions. The Descending Hierarchical Classification of the text indicates the existence of 7 categories of perception with related and statistically significant terms in the Chi-Square test. It was noted that ‘Ilhai do Mel’ is perceived as a place that is "worth" to be visited and that it has positive reviews and full of tips on how visitors can enjoy the best options during their visit.

Published: October 2022

The COVID-19 pandemic has forced all educational institutions worldwide to switch their active routine to ONLINE. With students attending classes virtually, a number of problems arose including the absence of social interaction and the imposed difficulty of digesting the materials of different courses, especially for those with a scientific background. General chemistry (GC), as an introductory course, is usually registered by students from different backgrounds, including Science, Engineering, and Agriculture. At the United Arab Emirates University, the second level of GC (GCII) is more focused on problem-solving as related to various topics. With the absence of face-to-face experience because of the COVID-19 circumstances, students’ understanding of the chemical concepts and implementing that in problem-solving has become a challenge. The current work investigates the effect of using professionally-made podcasts of GCII on the extent of understanding of students registered for this course during the period of 2020-2020 over a course of four semesters. The results of surveying the usage and feedback of students engaged in this experiment are outlined. Conclusively, this pedagogy is fully supported by most of the students who regard it as a suitable alternative to face-to-face settings.
SEPHARDIC MATRIMONIAL RELATIONSHIPS IN THE EARLY MODERN DIASPORA
Authors:   IAAS MSU, Moscow, Zaichenko Dariya A.
Published: October 2022

At first sight it may seem that family relationships lie just in the sphere of private life and historical sources which describe them may tell us little about the organization of Jewish community or about the interaction between the Jewish community and local non-Jewish authorities. However, the term ‘matrimonial relationships’ has a wide range of aspects. This work is an attempt to illuminate some of them. The article is dedicated to matrimonial relationships in the Jewish community of Avignon in the second half of the sixteenth century. It is made like a case-study and based on the scandal which happened at that time in the Jewish community of Avignon which was then a part of French holdings of the Pope, that’s to say the French part of the Papal States, and thus was controlled directly by the pope. The scandal is connected to the name of Bondion Crescas — a man who decided to marry the daughter of a woman with whom he passed the ceremony of halitzah several years ago. The intention brought about the opposition of the traditional rabbinate, that’s to say the majority of rabbis of Italy and Palestine as the conflict didn’t remain local one and rapidly became a subject of long disputes between different parties within the Jewish world. The study is based on hand-written documents, that’s to say on the Hebrew manuscript from D. Ginzburg’s Collection which has’t been decoded and studied before and is preserved in the Department of manuscripts of the Russian State Library. The process reveals three main issues. The first one is the Halakhic legality of marital intercourse between a man and the daughter of his haluzah (a woman with whom he must have got married a levirate marriage but released her). The second one is the social image of Avignon community in the 16th century, and the last one is the question about the boundaries of rabbinical jurisdiction in traditional Jewish society.
CONCERNING THE IMPACT OF GLOBALIZATION ON THE PROCESSES OF SPIRITUAL DEVELOPMENT IN JAPAN
Authors:   Institute of oriental studies, Russian academy of sciences (MOSCOW), Skvortsova Elena L.
Published: October 2022

The article focuses on the participation of Japan in the world globalization process and the features of the response to this process of the Japanese cultural tradition. It is concluded that there are three main stages in the spread of globalization processes in Japan: the Meiji era, the era of American occupation after World War II and the period from the 1970s. It is noted that in the 1960s and 1970s, Japan experienced the so-called boom of theories about Japanese identity (nihonjin-ron, nihon bunka-ron), reflecting the presence of a “contextual” personality in Japanese culture, in which an individual had an extremely high ability to act within the framework of interpersonal relations. The author recalls, that from the very beginning of Japan’s capitalist path, its outstanding intellectuals were aware of the danger of extreme individualism characteristic of the Western worldview, which viewed people as independent individuals driven by purely pragmatic interests. In Japan, on the contrary, each person traditionally felt himself / herself involved in a network of complex relationships, not only economic, but also universal human ties. It was obvious to Japanese intellectuals that the destruction of these traditional ties is fraught with the loss of national identity. It is stated that globalization, which in practice opposes the existence of national states, ultimately leads to the general elimination of national cultures that embody the specific features of human activity inherent in a particular community of people (both ethnic and professional, confessional, etc.) and reflecting the desire for cultural depersonalization. The author concludes that the efforts that the country’s ruling elite, despite the pressure of popular culture, are trying to direct to preserve the spiritual and moral core of the nation, help Japan, at least in part, to overcome the crises and upheavals of the era of globalism.

Published: October 2022

This paper reviews a study into the relationships between urban greenspaces and the benefits to psychological, social, and physical aspects of human wellbeing in a population using those environments. This relationship is theorized, analyzed, and measured through the transactional paradigm and is operationalized through the use of a public participation geographic information system (PPGIS), SoftGIS, which activates the greenspace - human wellbeing relationship through interaction and its map-based survey data collection. Over 1800 unique place-based relationships were analyzed. Results indicate what type of human wellbeing affordances were received from indicated greenspace within the Helsinki Urban Region. The implications are interdisciplinary and include community planning, urban geography, and human health as well as insight into the design and strategic management of greenspaces in urbanizing regions to provide continued and improved benefits to humans and nature.
India’s steps towards carbon dioxide monitoring in public assembly spaces for ventilation measurement for airborne infection control and other factors
Authors: Singh Raja
Published: October 2022

This commentary describes the work done by the Indian National Green Tribunal by instructing the Central Pollution Control Board to formulate guidelines and issue directions for important matters related to Indoor Air Quality and Airborne Infection Control. What started as a Public Interest Litigation in the Hon'ble Delhi High Court led to an application in the National Green Tribunal for three matters. The first being Carbon Dioxide monitoring of enclosed air conditioned spaces of public assembly nature as Carbon Dioxide is a surrogate for Ventilation in a space. The second being including inclusions in Split Air Conditioners as they simply recirculate the indoor air without any fresh air intake which increases probability of airborne infection spread apart from other issues. The last being having appropriate window design in building byelaws to promote openability of windows with wire mesh so that fresh air intake is possible for airborne infection control.
Optimizing the Shape of Signals with Quadrature Amplitude Modulation According to the Criterion of Given Reduction Rate of Out-of-Band Emissions
Authors: Makarov S. B. , Zavjalov S. V. , Ovsyannikova A. S.
Published: October 2022

Introduction. The growth in the volume of information transmitted through communication channels leads to their significant congestion. Almost all methods conventionally used to increase the data transfer rate in given frequency bands have been exhausted. In this regard, it is of interest to use new approaches aimed at improving the spectral efficiency of radio engineering and telecommunication systems by applying optimal signals that make it possible to use the bandwidth reserves of transmission channels given by Shannon's theory.

Aim. Improvement of the spectral efficiency of digital messaging systems by using signals with a compact spectrum and increased volume of the channel alphabet at the same time as minimizing energy losses.

Materials and methods. When searching for optimal signals, the mathematical apparatus of communication theory and functional analysis, as well as the methods of calculus of variations, were used. The evaluation of bit error rate performance of the obtained optimal signals transmitted in a channel with additive white Gaussian noise was performed in the MatLab environment. Results. It was established that, in a channel with additive white Gaussian noise, optimal signals with a signal constellation size of 64 in the case of quadrature amplitude-phase modulation provide an energy gain of more than 1 dB relative to signals obtained by narrowband filtering under the conditions of uncontrolled intersymbol interference. Optimal signals were shown to provide for an energy gain of 4.9 dB with respect to signals based on narrow-band filtering at a fixed spectral efficiency of 7 (bit/s)/Hz.

Conclusion. The paper proposes a method for improving the spectral efficiency of quadrature signals with amplitudephase modulation, based on the use of optimal pulse shapes obtained as a result of solving an optimization problem. The optimization problem was solved according to the criterion of minimizing out-of-band emissions with the constraint on bit error rate performance in case of amplitude-phase modulation. The energy and spectral efficiency of signals with optimal pulse shapes and signals based on narrow-band filtering were compared.
Comparative Analysis of Mathematical Models of Tracking Radio Altimeters
Authors: Monakov A. A. , Tarasenkov A. A.
Published: October 2022

Introduction. Tracking radio altimeters of low altitudes are widely used in civil aviation. These devises use periodic frequency modulated continuous wave (FMCW) signals, while altitude measurements are based on processing the beat signal processing. For this purpose, a closed automatic control loop is arranged to maintain the frequency of the beat signal at a fixed level by changing parameters of the transmitted signal (the frequency deviation or the modulation period). An alternative approach to arranging the tracking loop for altitude variations is based on the use of a phase locked loop (PLL), which adjusts the reference signal – a copy of the emitted signal – to obtain the maximum cross-correlation of the beat and reference signals. А comparative analysis of short-range radio altimeters with other currently known tracking radio altimeters for various types of frequency modulation of the transmitted signal seems to be a relevant research task.

Aim. An analysis of the influence of the type of frequency modulation on the accuracy of altitude estimation in a PLL-based radar altimeter, as well as a comparative analysis of this altimeter with other known tracking altimeters.

Materials and methods. Mathematical models of tracking radio altimeters are proposed, and a computer simulation of their performance is carried out for the case of altitude estimation over a smooth flat surface.

Results. The conducted comparative analysis of tracking radio altimeters confirmed the effectiveness of the PLL when processing signals of different frequency modulation type (sawtooth, triangular, and harmonic FM). Altitude estimates produced by PLL-based radar altimeters are unbiased, with their standard deviation not exceeding 3 cm for the signalto-noise ratio of greater than 10 dB and under the scenario parameters adopted in the work. The conducted comparison with other tracking altimeters showed that estimation errors of this radar altimeter are an order of magnitude smaller.

Conclusion. A PLL-based tracking radar altimeter can be used to estimate the height of the aircraft flight. The quality of altitude estimates produced by this device is higher than those produced by other known tracking radio altimeters. Further research and field tests will investigate the accuracy of altitude estimation when working over a rough surface.
A Calibration Algorithm for Microelectromechanical Inertial Sensors
Authors: Yen Nguyen Trong , Khanh Nguyen Quoc , Thang Ha Manh
Published: October 2022

Introduction. Systematic errors of microelectromechanical (MEMS) inertial sensors, such as those related to zero drift, scale factor, and nonorthogonality of sensitive axes, are the main sources of errors in strapdown inertial navigation systems (SINS). Uncompensated sensor errors accumulate over time as motion state errors, thus reducing the overall accuracy of SINS. Consequently, calibration of inertial sensors is a relevant research task. The disadvantage of existing sensor calibration methods consists in a strict requirement for the initial alignment of sensitive sensor axes relative to a reference coordinate system, which complicates the entire process of calibration. Therefore, alternative methods for MEMS sensor calibration should be developed.

Aim. To develop a calibration algorithm for microelectromechanical (MEMS) sensors, which allows calibrating sensors regardless of the angular orientation of the sensor axes relative to a reference coordinate system at the initial installation, as well as to simplify the design of testing tools.

Materials and methods. Publications in national and international journals on the theory of calibration of inertial sensors were reviewed. A calibration algorithm was developed based on the least squares method.

Results. An algorithm for determining the calibration parameters of sensors regardless of the initial alignment of the sensor sensitive axes relative to a reference system was developed. A simple alternative design for testing MEMS sensors was proposed.

Conclusion. The method of calibrating MEMS inertial sensors proposed in this work differs from conventional calibration methods by increased reliability of the results and a simplified design of testing tools. Importantly, the results of determining the calibration coefficients of a micromechanical accelerometer (MMA) do not depend on its angular position relative to a geographic coordinate system (GСS). This works contributes to improving the accuracy of SINS based on MEMS inertial sensors.

Published: October 2022

The COVID-19 pandemic has become a challenge to public health systems worldwide. As of June 2022, more than 545 million cases have been registered worldwide, more than 6.34 million of which have died. The gratuitous and bloody war launched by Russia in Ukraine has affected the public health system, including disruptions to COVID-19 vaccination plans. The use of simulation models to estimate the necessary coverage of COVID-19 vaccination in Ukraine will make it possible to rapidly change the policy to combat the pandemic in the wartime. This study aims to develop a COVID-19 vaccination model in Ukraine and to study the impact of war on this process. The study is multidisciplinary and includes a sociological study of the attitude of the population of Ukraine toward COVID-19 vaccination before the escalation of the war, the modeling of the vaccine campaign, forecasting the required number of doses administered after the start of the war, epidemiological analysis of the simulation results. This research targeted the COVID-19 epidemic process during the war. The research subjects are the methods and models of epidemic process simulation based on statistical machine learning. Sociological analysis methods were applied to achieve this goal, and an ARIMA model was developed to assess COVID-19 vaccination coverage As a result of the study, the population of Ukraine was clustered in attitude to COVID-19 vaccination. As a result of a sociological study of 437 donors and 797 medical workers, four classes were distinguished: supporters, loyalists, conformists, and skeptics. An ARIMA model was built to simulate the daily coverage of COVID-19 vaccinations. A retrospective forecast verified the model's accuracy for the period 01/25/22 - 02/23/22 in Ukraine. The forecast accuracy for 30 days was 98.79%. The model was applied to estimate the required vaccination coverage in Ukraine for the period 02/24/22 – 03/25/22. Conclusions. A multidisciplinary study made it possible to assess the adherence of the population of Ukraine to COVID-19 vaccination and develop an ARIMA model to assess the necessary COVID-19 vaccination coverage in Ukraine. The model developed is highly accurate and can be used by public health agencies to adjust vaccine policies in wartime. Given the barriers to vaccination acceptance, despite the hostilities, it is necessary to continue to perform awareness-raising work in the media, covering not only the events of the war but also setting the population on the need to receive the first and second doses of the COVID-19 vaccine for previously unvaccinated people, and a booster dose for those who have previously received two doses of the vaccine, involving opinion leaders in such works.

Published: October 2022

The study aims to increase the functional efficiency of a machine learning cyber attack detection system. An information-extreme machine learning method of the cyberattack detection system with optimization of control tolerances for recognition features that reflect the traffic properties of the info-communication system has been developed. The method is developed within the framework of the functional approach to modeling of cognitive processes of natural intelligence at the formation and acceptance of classification decisions. This approach, in contrast to known methods of data mining, including neuron-like structures, allows giving the recognition system adaptability to arbitrary initial conditions of the learning matrix and flexibility in retraining the system by expanding the recognition classes alphabet. The method idea is to maximize the information capacity of the attack detection system in the machine learning process. A modified Kullback information measure is used as a criterion for optimizing machine learning parameters. According to the proposed categorical functional model, algorithmic software for attack detection system in the mode of machine learning with the depth of the second level has been developed and implemented. However, the depth level is determined by the number of machine learning parameters, which were optimized. The geometric parameters of the recognition hyperspherical containers classes and the control tolerances on the recognition features were considered as optimization parameters, which played the role of input data quantization levels in the transformation of the input Euclidean learning matrix of the type "object-property" into a working binary learning matrix given in the Hamming space. Admissible transformations of the working training matrix of the offered method allow adapting the input mathematical description of the attacks detection system to the maximum full probability of the correct classification decisions acceptance. Based on the results of information-extreme machine learning within the geometric approach, decisive rules are constructed as practically invariant to the multidimensionality of the recognition features space. The computer simulation results of information-extreme machine learning of the attack detection system to recognize four host traffic of different profiles confirm the developed method's efficiency.

Published: October 2022

Ideation is a new way of thinking involving the diffusion of these ideas through social interaction in local, culturally homogeneous communities. Making decisions about behavior depends on ideation factors. This study aimed to determine ideation factors associated with long-acting contraceptive behavior among family planning (FP) clients in East and North Jakarta. The data was derived from the "My Choice District Mini-Survey" conducted in East and North Jakarta between November and December 2016. The sample involved 720 women from both districts using a multi-stage cluster sampling process. An ideation factor was constructed from knowledge, attitude, social support, and interpersonal discussion on "Long Acting and Reversible Contraception" (LARC). A logistic regression analysis was performed to identify the most dominant factors associated with long-acting contraceptive behavior. This study found that the number of family planning clients who used LARC was 223 (30%). Of the percentage of using LARC attributed to each ideational score, the highest was 47%, and the lowest was 11%. The knowledge of LARC that can be used for spacing was the strongest ideation variable with Adjusted Odds Ratio (AOR) = 4.55 (95% CI = 3.13 -6.61; p-value =0.000); followed by limiting with AOR 3.46 (95% CI 1.61 - 7.45; p-value= 0.001). The study confirmed the correlation between ideation factors on LARC and its use. To increase the number of LARC users, we should improve the supply side program by increasing FP clients' knowledge about LARC and shifting attitudes on LARC into positives.

Published: October 2022

Diabetes Mellitus (DM) is a group of metabolic diseases with hyperglycemia characteristics that can lead to  kidney complications. One of them is Diabetic Nephropathy which is a complication of microvascular damage and its monitoring is done by checking serum creatinine and creatinine clearance test (CCT). The purpose of this study was to determine the relationship between serum creatinine levels and creatinine clearance test (CCT) in patients with type 2 DM. Perform a serum creatinine examination which is used as the basis for calculating CCT. From 53 data on type 2 DM patients who had high serum creatinine levels, 49 (92.5%) people, 51 (96.2%) people with low CCT levels. The results of Spearman's correlation statistical test showed a correlation between serum creatinine levels and CCT. The strength of the correlation is moderate, and the correlation shows a negative direction with a correlation coefficient (r) of -0.389. It can be concluded that the higher the serum creatinine level, the lower the CCT value, so DM patients must control blood glucose regularly in order to prevent a decrease in kidney function that can lead to complications.

The complex of TAIF-NK JSC, which operates on the basis of Veba Combi Cracking (VCC) technology, is the only one in the world that allows processing of heavy residues (Vacuum Residue) obtained by primary distillation from crude oil, with maximum production of high-quality light oil products. Implementation of hydrocracking technology on the basis of VCC technology at TAIF-NK JSC ensured the achievement of oil refining depth and light product yields for 2021 - 85.1% and 80.7% respectively. The article demonstrates the retrospective dynamics of indicators of oil refining depth and light oil products draw-off from implementation of the project, the change in the food basket, as well as highlights the problems that arose in the course of implementation of the project.

Currently, the main products of the delayed coking plant in the Russian Federation (after hydrotreating) are gasoline and diesel fuel summer. The paper presents the results of a study of the properties of narrow fractions of coking gas oil and hydrotreated coking gas oil, which showed the prospect of organizing production based on the coking process of more marginal aviation kerosene and winter diesel fuel. The separation of products into narrow 20 degree fractions was carried out on an automatic distillation unit AUTOMAXX 9100. The dependences of nitrogen, sulfur, aromatics, density, and low-temperature properties on the boiling temperatures of narrow fractions of the composition of light coking gas oil and hydrotreated light coking gas oil have been studied. Analysis of the properties of narrow fractions of hydrotreated light coking gas oil has shown the theoretical possibility of obtaining fractions of jet fuel and winter diesel fuel on its basis, instead of summer diesel fuel.

Analytical information is presented on the development and implementation of new technical requirements for the performance properties of motor oils and new methods of testing them in the specifications for promising automotive engines, taking into account global trends in environmental protection. Taking into account the latest diesel designs, the European Association of Automakers (Association des Constructeures Europe'enes d’ Automobiles - ACEA) has updated the specifications for engine oils for high-power diesels this year, including low-viscosity oils with an extended shift interval. The changes do not directly concern the assessment of the energy-saving properties of motor oils - saving fuel consumption when using them. ACEA is updating its specifications for heavy-duty heavy-duty diesel engines three years later than their originally planned adoption by the end of 2018. Two new oil categories E8 and E11 have been added to the 2022 ACEA specification with simultaneous replacement of categories E6 and E9, respectively, declared obsolete. The possibility of using potentially new methods for evaluating their properties - the ability of oils to reduce high-temperature engine wear and the amount of deposits in the turbocharger - is being considered when testing oils of the new GF-7 category. The use of upgraded methods is proposed: a new Noack test to determine the volatility of oils to assess their volatility and consumption, an updated Ford method to assess the pre-ignition of the fuel mixture at low speeds and high torque to ensure engine protection during the service life of the oil. Finally, a number of Original Equipment manufacturers (Original Equipment Manufacturer - OEM) assume the use of low–viscosity oils of classes 0W-8 and 0W-12 according to SAE for their engines, and these brands are likely to be included in the list of tested oils of the GF-7 category according to the new ILSAC specification.

The article is devoted to the study of the process of bitumen BND-60/90 cooling in an elevated vertical steel tank. Attention to this issue is dictated by the fact, that the specific properties of the product increasing viscosity and tendency to solidification during cooling — create difficulties in its operational turnover for the operators, and storage at high temperature leads to deterioration of the commodity properties. The relevance of the study comes from the need to find an energy-efficient solution for enterprises which accept, store and promptly dispense bitumen on an industrial scale. The work was conducted in order to explore the possibility of reducing energy consumption, while heating the product, by optimizing the design of the heater. The object of the research was an insulated tank RVS-3000 with a fixed roof, the prototype of the same volume of which was built by Himstalcon-Engineering LLC in Kaluga. It is assumed, that this tank was filled with bitumen heated to a temperature of 160⁰С. In this work the distribution of the temperature field, as well as the field of velocity of bitumen movement over the volume of the tank, were obtained. This allowed us to formulate preliminary conclusions about promising directions for the development of technologically and energetically efficient methods of maintaining its temperature.
The Asian Americans’ Identity Crisis as Reflected in Day Standing on Its Head

Published: October 2022

Philip Kan Gotanda's heritage is professionally woven into nearly all of his work. The combination of family memories and theatrical inventions makes him the faithful chronicler of the Asian American experience. The past visibly invades the present in most of his works and characters, while he interweaves a distinctly theatrical magic charm around them, producing a crystal clear picture of Asian American life. His plays feature arguments between men and women with differing visions of how Asian Americans should fight to be a part of America.   One can say that it would be more challenging to assign Day Standing on Its Head as a merely Asian American play because Gotanda exposes socio-cultural issues that can fit all the mainstream audience. Although the characters in this play confront problems rooted in the particularities of Japanese American history and culture, their conflicts reveal psychological and emotional realities that resonate beyond the Japanese American community. Along with all of Gotanda's works, he never sacrifices his ethnic authenticity to gain the acceptance and visibility of the mainstream audience. On the other hand, he claims the right to present the "real" face of the Asian American problems, issues, and conflicts, just to record their real life without any decoration. Gotanda argues that his style in discussing these issues can help in strengthening relations with the mainstream.

As is well known, general election activities and the election of leaders in the regions are a necessity in state activities. This activity has also been taking place in Indonesia since Indonesia proclaimed Indonesia's independence in August 1945. However, with the passage of time, this election activity is felt to have caused and/or left various conflicts that could become potential divisions, and events like this are certainly far from the spirit and ideals. the noble ideals and culture of the Indonesian nation. For this reason, this activity is intended to remind the younger generation, in this case the students of President University, to continue to uphold Indonesian local wisdom in their daily lives, including responding to various differences in daily life.
