Human Values and behaviour in the Context of COVID-19
Authors: Dey Suparna
Published: February 2023

The novel coronavirus disease or COVID-19 emerged at the end of December 2019. It has caused immense effect on the economy, human society, health system, human psychology, daily life and livelihood of human beings around the world. In India this deadly virus first attacked in Mumbai and turned to be a pandemic after rapid transmission throughout the country. During this pandemic thousands of people died due to the infection of the virus. The citizens of India became witness of an unnatural and heart throbbing situation which they had never seen before. In this adverse situation human values like faith, love, respect, affection, self-confidence, responsibility started to deteriorate and reached to the bottom line. Human behaviour is influenced by these human values. Naturally people's behaviour started to deteriorate towards others in this pandemic situation. They began to show disrespect to others, hatred and negligence to a corona patient, selfish and self-centered attitude to protect themselves only. In my opinion, most of us were compelled to show these type of negative behaviours at the beginning of this pandemic, because there was no vaccine and no treatment during those days. But today we have already spent almost one and half year in this abnormal situation and started to believe that COVID-19 does not mean death only, rather the probability of recovery from this disease is high if we follow some good habits and practices like hand-washing, wearing face mask, maintaining social distance, maintaining cleanliness etc. Now-a-days almost everyone of us is following these good practices and precautionary measures, because we have come to know that these practices will protect us from the coronavirus. Today we are all optimistic and confident that a day will definitely come when our beloved earth will be out of the adverse effect from this invisible enemy.

Authors: Puljak Livia , Makaric Zvjezdana Lovric , Buljan Ivan , Pieper Dawid
Published: February 2023

Aim:
To analyze descriptors/definitions of meta-epidemiological studies as well as study design of articles that were self-described as meta-epidemiological studies.
Methods:
We searched MEDLINE and Embase on 6 August 2019. We extracted definitions of meta-epidemiological studies, as well as study designs, statistics and units of analysis that were reported in studies self-labelled as meta-epidemiological studies.
Results:
We included 175 information sources in the analysis. Definitions of meta-epidemiological studies varied and some studies used the term meta-epidemiological study to describe methodological research-on-research studies. Less than a half of the studies (n = 54; 42.9%) used the two-step meta-epidemiological approach in data analysis. Among studies self-labelled as meta-epidemiological, 9.4% reported registration in PROSPERO and 11% indicated they reported the study in line with PRISMA.
Conclusion:
Research community would benefit from consensus about definition of meta-epidemiological study.
Comparison of intravenous versus topical tranexamic acid in primary total hip arthroplasty: a systematic review and meta-analysis of ten randomized trials
Authors: Fang Yan , Shang Xiaobin
Published: February 2023

Aim:
The optimal management approach for tranexamic acid (TXA) in primary total hip arthroplasty (THA) is still controversial. This meta-analysis aimed to evaluate the efficacy and safety of intravenous versus topical TXA during THA.
Materials & methods:
PubMed, Google Scholar, Embase and the Cochrane library were searched for all randomized controlled trials comparing topical and intravenous TXA (iTXA) following primary THA. The primary outcome consisted of blood loss including total blood loss, intraoperative blood loss and hidden blood loss (HBL), hemoglobin (Hb) level of postoperative day 1, maximum Hb drop and transfusion incidence. The second outcome included drainage volume, complications and length of stay. Extracted data were statistically analyzed with the Stata11.0.
Results:
A total of ten randomized controlled trials containing 1295 patients were included in the study. A similar effect of transfusion rate, total blood loss, Hb level of postoperative day 1, drainage volume, deep vein thrombosis events and wound complications appeared in the two routes. Intraoperative blood loss (weighted mean difference [WMD] = -12.687, 95% CI: -22.291, -3.083; p = 0.010), HBL (WMD = 14.276, 95% CI: 9.936, 19.459; p < 0.001) and maximum Hb drop (WMD = -0.400, 95% CI: -0.577, -0.222; p < 0.001) were significantly reduced in the intravenous group compared with topical group.
Conclusion:
The present result indicated comparable safety and transfusion rate for intravenous and topical TXA in primary THA, while the intravenous approach demonstrated a smaller intraoperative blood loss, HBL and maximum Hb drop.

Authors: Susiang Maria Imelda Novita , Djamil Masydzulhak , Saluy Ahmad Badawi , Siswanti Indra
Published: February 2023

2020 is the most difficult year in the start-up world due to the Covid-19 pandemic existed since the end of 2019 which forced every effort to turn the direction of strategy. Not a few also experience a crisis in the time of pandemic, so some companies have laid off their employees to reduce the burden of financing. The business sectors most affected are the commercial aviation, travel, oil and gas, automotive and banking sectors. But the business of the MSME sector is also affected due to the availability of raw materials and social restriction regulations.  By applying the Action Research methodology from the literature study of post-pandemic phenomena, the study used a compilation data source to support this writing literature research. The focus of this writing is the MSME sector businesses that are still operating in the post-Covid-19 pandemic. Almost all business people in the MSME sector experienced a very drastic decrease in sales turnover, experiencing various marketing and sales constraints, as well as product distribution. Some business actors in the MSME sector are trying to maintain their business or business in the middle until after the Covid-19 pandemic by following government rules and health and security protocols with various efforts observed (observe), identified (to orient), make decisions (decide), and re-activity (to act) by continuously observing, identifying, making decisions, and acting continuously in one unconstrained cycle time. This study employs and implements an OODA loop or cycle. The concept of OODA loop is the concept of repeated analysis to determine the decision of a problem. OODA stands for Observe, Orient (problem identification), Decide (quick decision making), and Act (immediate action). The term cycle or loop comes from this concept because every process repeats until decisions taken are effective and able to have a significant impact in dealing with problems. For this reason, it is recommended that every business actor can try this method as a solution to the challenge of overcoming the economic crisis caused by COVID-19 through the OODA loop.
Board guidance for company climate opportunities
Authors: Grove Hugh , Clouse Maclyn , Xu Tracy
Published: February 2023

The major research question of this paper is whether net-zero pledges are a dangerous trap for boards of directors’ guidance and monitoring of their companies’ climate activities and opportunities. There is no current consensus on how to do so. Professor Bob Garatt is the Director at Good Governance Development Ltd, a London External Examiner at Gulf Cooperation Council Board Development Institute. He recommended the following research paper as an important and wise caveat that all boards need to consider as an antidote to easy ESG (environmental, social and governance) rhetoric and accounting. Dyke, Watson, and Knorr (2021), in their paper, “Climate Scientists: Concept of Net-Zero is a Dangerous Trap” provide guidance for boards to assess their companies’ climate activities and opportunities. Their research is summarized in two sections of this paper. This paper expands our five prior research papers, which focused upon specific board responsibilities for various aspects of climate impacts on their companies. To avoid this dangerous trap of net-zero pledges, our current paper provides an overall climate perspective for boards, providing guidance for the board of directors’ responsibilities for assessing the role of their companies in climate activities and opportunities. It is critical for boards to develop guidance and actions for monitoring companies’ climate activities and opportunities

Authors: Boonnarakorn Sawitree , Deebhijarn Samart , Sangmanee Woranat
Published: February 2023

Over the past several years the COVID-19 pandemic has devasted Thailand’s economy while simultaneously destroying the ability of numerous snack food enterprises to sell their home-grown products domestically and to export to the broader international community. Therefore, the purpose of the research was to investigate which factors affected the export performance (XPE) of Thai One Tambon One Product (OTOP) entrepreneur snack food products. From a list of OTOP export producers, the authors used systematic random sampling across six Thai regions to select the study’s 311 export entrepreneurs. The structural equation model (SEM) analysis used LISREL 9.1 to determine the validity of the causal model and the variable interrelationships and how they affected OTOP snack food XPE. The SEM results revealed that innovative products (IPT), innovative processes (IPS), packaging design (PAD), the marketing mix strategy (MMS), and product quality (PDQ) all positively influenced XPE. Also, the total effect values for MMS, PAD, PDQ, IPT, and IPS, were 0.27, 0.22, 0.21, 0.15, and 0.05, respectively. Nine of the eleven hypotheses examined were supported, with PAD being shown to strongly influence MMS. This paper makes a significant contribution to the global discussion concerning rural poverty reduction, rural employment, and entrepreneurial handicraft export performance.

As we approach the three-year anniversary of the pandemic, we are now
facing a seasonal influenza epidemic after two years without one. In
light of growing concerns over the potential risk of a “twindemic,”
the Republic of Korea is currently experiencing the first peak of
seasonal flu and the overall pattern is quite similar to that observed
before the COVID-19 pandemic. Notably, no sudden or early increase in
cases has been detected, which is unique compared to other countries.
Asymptotic behavior of the Boussinesq equation with nonlocal weak damping and arbitrary growth nonlinear function
Authors: Mo Yichun , Ma Qiaozhen , YAO Lijuan
Published: February 2023

In this paper, we consider the asymptotic behavior of the Boussinesq
equation with nonlocal weak damping when the nonlinear function is
arbitrary polynomial growth. We firstly prove the well-posedness of
solution by means of the monotone operator theory. At the same time, we
obtain the dissipative property of the dynamical system (E ,S(
t)) associated with the problem in the space H 0 2 ( Ω ) × L 2 (
Ω ) and D ( A 3 4 ) × H 0 1 ( Ω ) , respectively. After that, the
asymptotic smoothness of the dynamical system (E ,S( t))
and the further quasi-stability are demonstrated by the energy
reconstruction method. Finally, different from [21] we show not only
existence of the finite global attractor but also existence of the
generalized exponential attractor.
Optimization of YOLOV7's hyper parameters for simultaneous object detection in satellite imagery
Authors: Singh Abhimanyu , J Manisha Nene
Published: February 2023

Object detection is crucial for computer vision applications that use
satellite imagery, such as precision agriculture, urban planning, and
military applications.Recognizing objects in satellite images is
challenging due to numerous factors, including the sheer number of
objects, the variety in their positions, the range in their sizes, the
quality of the lighting, and the existence of a dense
background.Background complexity, differences in data capture geometry,
geography, and illumination, and an abundance of different types of
objects all contribute to making automatic detection in satellite images
particularly difficult.There have been many advancements in object
detection methods over time, including YOLO and its variations, CNN and
its offshoots, DETR and its offshoots, and so on; nonetheless, it is
still required to test these methods on the requisite data set to
determine their true efficacy.Researchers have investigated the idea of
autonomously detecting structures, automobiles, and other things to
reduce the risk of human error and speed up the procedure.Improvements
in deep learning algorithms and hardware systems have allowed us to
accurately identify a broader range of objects in ultra-high-resolution
satellite imagery.Through parameter adjustment and analysis of results
on the Xview dataset, we determine the most effective technique for
multiple item detection and compare it to other models.

The oceanic storage of anthropogenic CO
(C) that humans have emitted into the atmosphere has
been pivotal for counteracting climate change. Yet multi-decadal trends
in the ocean interior storage of C have not been
assessed at global scale. Here, we determine storage changes of
C by applying the eMLR(C*) regression method to ocean
interior observations collected between 1989 and 2020. We find that the
global ocean storage of C grew by 29 ± 3 Pg C
dec and 27 ± 3 Pg C dec (±1σ)
from 1994 to 2004 and 2004 to 2014, respectively. Although the two
growth rates are not significantly different, they imply a reduction of
the oceanic uptake fraction of the anthropogenic emissions from 36 ± 4
% to 27 ± 3 % from the first to the second decade. We attribute this
reduction to a decrease of the ocean buffer capacity and changes in
ocean circulation. In the Atlantic Ocean, the maximum storage rate
shifted from the Northern to the Southern Hemisphere, plausibly caused
by a weaker formation rate of North Atlantic Deep Waters and an
intensified ventilation of mode and intermediate waters in the Southern
Hemisphere. Between 1994 and 2004, the oceanic C
accumulation exceeded the net air-sea flux by 8 ± 4 Pg C
dec, suggesting a loss of natural carbon from the
ocean during this decade. Our results reveal a substantial sensitivity
of the ocean carbon sink to climate variability and change.
Some results of reverses young’s inequalities

Published: February 2023

In this paper, we present some refinements of reverse Young?s inequalities.
Among other results, a refinement of reverse operator Young inequalities
says A?vB + 2?(A?B ? A?B) ? m??M m??M / A?vB, where 0 < mI ? A, B ? MI, ? =
min{v, 1 ? v} and v ? [0, 1], extending a key result in [J. Math. Anal.
Appl. 465 (2018) 267-280] and [Linear Multilinear Algebra 67 (2019)
1567-1578]. Furthermore, we give a reverse of Young?s inequalities due to
[Math. Slovaca 70 (2020), 453-466]. Moreover, we give a generalization of
reverse Young-type inequality, and we also show a new Young-type inequality
which is either better or not uniformly better than the main results in
[Rocky Mountain J. Math. 46 (2016), 1089-1105]. As applications of these
results, we obtain some inequalities for operators, Hilbert-Schmidt norms,
unitarily invariant norms and determinants.

Conformable fractional Fourier transformation of tempered distributions
Authors: Abdullah Saleh
Published: February 2023

In this paper we introduce a new definition of fractional Fourier
transformation on the space S of Schwartz test functions and study some of
its properties. It turns out that this fractional Fourier transform has many
properties with the conformable fractional derivative that the conventional
Fourier transform has with the conventional (standard) derivative. We
establish some operational formulas for the new transform, and give a left
inverse for it. We use duality to define fractional Fourier transform of
tempered distributions. Finally, we give two applications to ordinary and
partial differential equations.

Introduction. Without a comprehensive postmortem investigation it is impossible to determine the cause of death among the SARS-CoV-2-suspected and -positive patients. We present two cases to discuss the postmortem detectability of SARS-CoV-2 virus and RNA stability in biological samples. Outline of cases. Case No. 1: a 40-year-old man on whom the autopsy was performed four days after death. The body was stored at 4?C. Bilateral pneumonia was confirmed grossly and histopathologicaly. Molecular testing was positive for IgM antibodies, but negative for SARS-CoV-2 RNA. Case No. 2: a 28-year-old professional basketball player who suffered from SARS-CoV-2 about a month earlier. The autopsy was performed two days after death. The body was stored at 15?C. Gross autopsy findings revealed advanced putrefactive changes and an enlarged heart, with visible fibrotic focuses. The histopathological finding corresponded to the sudden cardiovascular death due to the cardiac dysrhythmia most probably formed in one of the fibrotic focuses. Tests for SARS-CoV-2 RNA and antibodies (IgM, IgG) were positive in the analyzed samples. Conclusion. This report suggests that SARS-CoV-2 virus can be isolated in the biological samples even after a long post-mortem prolongation of molecular analyses. We emphasize the necessity of wider studies that will define the infectiveness and biological stability of the virus in postmortem tissues.

The paper provides information on the biological parameters and feeding of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) that has entered the Krasnoyarsk Reservoir by escaping from fish farm cages. In the diet of the studied individuals, eleven groups of food components are found; imagoes of terrestrial insects and chironomid larvae dominate in ration. At the same time, studied individuals are characterized by slow linear and weight growth, low condition factor and stomach fullness, as well as a significant presence of non-food components in food boluses, indicating an insufficient supply of wild population with food resources. In addition, studied fish are characterized by a high degree of morphological malformations of the axial skeleton, which could affect their locomotor functions and ability to reproduce. Therefore, emergence of a self-reproducing population of rainbow trout in the Krasnoyarsk Reservoir is currently assessed as unlikely.

Visually identifiable morphological features serve as distinctive signs of individuals and may indicate the state and sex-age structure of populations of large mammals. The development and change of morphological structures may occur under the influence of various factors, including human economic activity. The article proposes a classification of dewlap and antler morphotypes of the population of the European elk (Alces alces alces (L., 1758)), living on the territory of the Leningrad Province (North-West of Russia). Frequency of occurrence of observed morphotypes is analyzed and discussed considering the data of long-term observations conducted in 2015-2020 at 20 artificial salt licks located on 11 experimental sites in three districts of the region. Based on the studied material, the following morphotypes of the dewlap are identified: “icicle”, “drop”, and “fold” (halberd, triangular, rounded). In females, the dewlaps of the “icicle” and “drop” type dominate, the “fold” is noted very rarely. In males, on the contrary, the “fold” is most often encountered. The antlers may be palmated, cervine, intermediate, transitional, “spike”, “fork”, and abnormal. Palmate and cervine antlers are found with almost the same frequency of occurrence (about 25%), a lower number of cases is noted for “spikes” and “forks”, as well as for intermediate type of antlers; transitional and abnormal antlers are recorded the least. The analysis of literary sources devoted to the classification and variability of the studied morphological characters has been also carried out.

Due to the large amount of pollution at coal spoil heaps, soil reclamation is slow and requires development and use of microbial preparations, selected based on assessments of the biochemical parameters of soil and the extent of its contamination. The material for this study was mine soils sampled in three different zones (Ka, Kb, Kc) of the Korchakol coal spoil heap. The studied sanitary and chemical indicators did not exceed the approximate permissible concentrations (APC) / maximum allowable concentrations (MAC), except for oil products (in the Ka, Kb, Kc zones, the excess averaged 2.2, 1.4, 1.2 times, respectively). The study found a direct correlation between the zinc content and the enzymatic activity of polyphenol oxidase, the level of Ni and peroxidase, as well as an inverse correlation between the As and Cu concentrations with invertase and nitrite reductase, respectively. The index of bacteria of the Escherichia coli group (coliform bacteria) in different zones exceeded the standard values by 61 and 171 times. Even though the sanitary indicators studied do not exceed permissible levels, they can slow down growth and development of plants. Thus, successful reclamation of mine soils requires introduction of biological preparations based on microorganisms that biotransform heavy metals and rhizobacteria.

This study focused on establishing the relationship between sugarcane growing and the livelihood of small-scale farmers in Jinja District.  It was guided by three objectives namely: to characterize individual farmers and their farms, establish benefits from sugarcane farming to the farmer’s livelihoods and find out the effect of sugarcane growing on household food security in the area. The study adopted descriptive research design. The target population of this study were sugarcane growing households’ heads and Village Chairpersons of sugarcane out-growers association.  The study employed the purposive and simple random sampling techniques. A sample size of 42 respondents from a population of 362 small-scale farmers.  The methods of data collection included; use of questionnaires, interviewing, focus group discussions and observation.  The study generated both qualitative and quantitative data. The data collected was analysed by computing percentages while qualitative data was analysed by coding and establishing common themes. The study findings revealed that although women are fully involved in sugarcane growing, ownership of farms is dominated by men. The dominant age group among the sugarcane farmers is between 30 to 60 years, with mainly primary education graduates. The average farm size was 3 acres and the larges part of the farm land is devoted to sugarcane growing. There are some positive benefits from sugar growing, though many challenges have been identified. Most smallholder farmers are experiencing food insecurity.  Based on the findings of the study it was recommended that there was need to encourage people owning land less than five acres to practice mixed farming, use scientific methods of farming such as intercropping, crop rotation, use fertilizers to facilitate better yields and crop diversification to improve both on their earnings and food security.
