Published: November 2021

AbstractCopula model is a method that can be implemented in various study fields, including analyzing wildfires. The copula distribution function gives a simple way to define joint distribution between two or more random variables. This study aims to review the application of copula in the analysis of wildfires using a Systematic Literature Review (SLR) and provide insight into research opportunities related to the application in Indonesia. The results show there are very few articles using the copula model in the analysis of wildfires. However, the increasing number of article citations each year shows the importance of such article research and has contributed to wildfire analysis development. In that article, 50% of studies applied the copula model to direct wildfire analysis (using fire data) in Canada, Portugal, and the US. Meanwhile, the other 50% use the copula model for indirect wildfire analysis (not using fire data) in Canada and the European region. The outcome of the presented review will provide the latest research positions and future research opportunities on the application of copula in the analysis of wildfires in Indonesia.Keywords: copula; wildfire; systematic literature review.

BACKGROUND AND OBJECTIVES
Sudden unexpected infant death often results from unsafe sleep environments and is the leading cause of postneonatal mortality in the United States. Standardization of infant sleep environment education has been revealed to impact such deaths. This standardized approach is similar to safety prevention bundles typically used to monitor and improve health outcomes, such as those related to hospital-acquired conditions (HACs). We sought to use the HAC model to measure and improve adherence to safe sleep guidelines in an entire children’s hospital.

METHODS
A hospital-wide safe sleep bundle was implemented on September 15, 2017. A safe sleep performance improvement team met monthly to review data and discuss ideas for improvement through the use of iterative plan-do-study-act cycles. Audits were performed monthly from March 2017 to October 2019 and monitored safe sleep parameters. Adherence was measured and reviewed through the use of statistical process control charts (p-charts).

RESULTS
Overall compliance improved from 9% to 72%. Head of bed flat increased from 62% to 93%, sleep space free of extra items increased from 52% to 81%, and caregiver education completed increased from 10% to 84%. The centerline for infant in supine position remained stable at 81%.

CONCLUSIONS
Using an HAC bundle safety prevention model to improve adherence to infant safe sleep guidelines is a feasible and effective method to improve the sleep environment for infants in all areas of a children’s hospital.
The Determinants of Debt Load for Companies in Emerging Markets
Authors: Klestov Mark , Jindřichovská Irena 
Published: November 2021

Corporate capital structure is one of the key elements of long-term development, which determines the company value.Consequently, defining the factors that influence the debt load level of a company and, hence, its capital structure is also of great importance.
In this paper we have collected a sample of data of 753 Russian companies and 292 Brazilian companies for 2020 to evaluate the influence of various factors on their debt-load level. The data was downloaded from Bloomberg database and the basis of the analysis focuses on evaluation of conventional academic theories on capital structure, and a regression analysis based on variables extracted from a set of original hypotheses.
Among our results, our analysis illustrates that individual sets of determinants differ significantly in explanatory power, and operate unequally when contrasting Russian companies and Brazilian ones. Additionally, it was established that when companies define their debt load, they do not limit themselves to a single theory of capital structure. We conclude, inter alia, that it is impossible to identify with confidence which of the examined theories companies are most likely to follow in their actions, because observed interrelations between relevant variables and debt load have indications of various academic theories.
How Patents Influence Market Value of Industrial Enterprises' Assets?
Authors: Dementev Dmitry 
Published: November 2021

Scientists and engineers are continuously patenting innovative ideas such as inventions, industrial designs, and utility models. It is therefore relevant to pose the question of the influence of intellectual property in the field of innovative technologies on the market value of the assets of industrial enterprises.
We analyse the dependence of the results of intellectual activity in the field of advanced technologies on the capitalization of innovative industrial production after the adoption of the developed technologies. We consider patent landscapes, analyse research publications, and study the dependence of financial indicators on the results of intellectual activity at enterprises producing computers, optics and electronic equipment.
Our research methodology is based on the statistical analysis of the dependence of the financial results of industrial enterprises on the actual application of the results of intellectual activity to the technological process. We define the object of analysis by citing research articles and surveys from the WoS database. The patent landscape is assessed using data from commercial information systems such as Orbit Intelligence (Questel) and Amadeus (Bureau van Dijk, Moody’s Analytics) that make it possible to visually show the links between patent activity and technological trends in the computer and electronic technology industries.
The research results shall be useful for assessing the effectiveness of employing patents in manufacturing and the prospects of improving production technologies for the formation of corporate innovative technological policy.
We conclude that the use of information on patent trends is an effective tool for increasing the competitiveness of enterprises producing electronic equipment. The priority financing of innovative technologies ensures the sustainable development of the manufacturing industry and have a positive impact on the profitability of enterprise assets.

Published: November 2021

Comparative retrospective analysis of serum marker proteins (AFP and hHG), ultrasound examinations and fetal karyotypes was carried out in 306 high risk pregnancies of chromosomal anomalies. Peculiarities of pregnansy histories, birth complications and their outcome were considered respektive of maternal serum hHG values registered at 13-21 weeks of gestation.
Statistically significant deviations of maternal serum proteins (MSP) values were registered almost with equal probabilities ih the groups of high risk pregnancies of chromosomal disorders as well as in the women with noncomplicated pregnansy histories (56,7% and 59,3% respectively).
Chromosome abnormalities were registered in 29 out of total 306 fetuses subjected to invasive karyotyping. 11 out 20 women with chromosomally abnormal fetuses revealed substantial deviations of MSP values. All cases of chromosomal abnormalities correlated with maternal age (over 35) and ultrasound markers in the foetuses. Elevated values of hHG in maternal blood correlated with unfavourable pregnansy outcome.

As to continue my 50-year period of work in medicine, I noted the way the medical science is developing in the fatherland. And as I have seen its quick development I could have hardly stay not amazed. For half-century before that we were only students and the followers of our leaders - foreign men, because we didnt have any native leader in any of the medicine field. But now, thanks God...we are equal to their level and can do our way ourselves.

Published: November 2021

Salivary gland lesions are one of the most common encounters in clinical practice for the evaluation of which Fine needle aspiration cytology is a well-established technique nowadays. Owing to the heterogenecity and morphological overlap between the various categories of these salivary gland lesions, there was a need for a standardised procedure. The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) provides a standardised evidence based reporting system to assess the risk of malignancy and thus helpful for the management of these lesions. We have undertaken this study for evaluation of salivary gland lesions by this newly introduced grading system for predicting the malignant potential of these lesions.: We have done a prospective study of all the salivary gland lesions received in our department for a period of 3 years from 2016 to 2019. The clinical history, aspiration cytology and histopathological examination was done for all the cases.: We have received 225 salivary gland lesions for aspiration, but histological follow up was done in only 105 lesions, which were thus included in our study. Case distribution into different categories was done in the following way:ND (5.71%), NN (38.01%), AUS (2.57%), NB (33.34%), SUMP (1.9%), SM (2.85%), and M (15%). Overall, ROM reported were 25%, 5%, 20%, 4.4%, 33.3%, 85.7%, and 97.5%, respectively for each category. Overall, sensitivity was 83.34%, specificity was 98.01%, positive predictive value was 94.87%, and negative predictive value was 91.89%. MSRSGC is a six category scheme that was recently proposed that separates the salivary gland FNAC into distinct categories, thus increasing the specificity by limiting the number of false negative and false positive cases.

Introduction: Dental treatments have a high-risk nature due to the close relationship between the patient and direct exposure to saliva, blood, etc. Concerns about the transmission of COVID-19 infection have led to the formation of some form of patient fear. Therefore, considering the importance of mental health, the present study was designed to investigate the degree of anxiety in people with COVID-19 through dentistry.Material and Methods: In the present descriptive study, 384 questionnaires were randomly distributed among the patients of Sari Dental Clinic in the period of April to June 2021. After the necessary explanations and obtaining informed written consent, the questionnaires were completed by the clients. Finally, the data were analyzed using SPSS V.22 software and statistical tests. Values greater than 0.05 were also considered significant.Results: In this study, 29.2% were male and 68.8% were female, and corona-related anxiety was more common in women and married people. As they got older, they tended to respond to higher options like most of the time or always. The higher the level of education, the less noticeable the unnecessary visits to the dental clinic.Conclusion: People were more worried about transmitting the disease to those around them and this anxiety was more in women than men. Married people were also more anxious than single people. Anxiety was significantly higher in the unemployed than in the employed. There was a significant relationship between degree and level of anxiety and people with higher education levels showed more anxiety.

Introduction: Metabolic syndrome includes a range of disorders that increase the risk of cardiovascular disease and diabetes mellitus. In this study, we examined the serum level of vitamin D3 in diabetic individuals with metabolic syndrome compared with non-diabetic individuals without metabolic syndrome and the association of serum vitamin D3 levels with metabolic syndrome and atherogenic factor (LDL/HDL).
Material and Methods: In a case-control study, we included 110 women with metabolic syndrome according to ATP III criteria and 127 healthy women as a control group. Serum concentration of total cholesterol, LDL-C, FBS, HDL-C and serum triglyceride determined by enzymatic method and colorimetric and, serum level 25-(OH) vitamin D determined by ELISA.
Results: It was found that the two healthy and metabolic groups were significantly different in terms of total cholesterol levels, LDL and triglyceride levels, HDL, VLDL, FBS, atherogenic index (LDL/HDL) and vitamin D levels (p<0.05). All participants in the control group and the patient and the whole study population were divided into two categories of insufficient and sufficient based on their measured serum concentrations of 25-(OH) vitamin D. There was a significant difference between the group with insufficient levels of vitamin D in comparison with the group with sufficient levels of vitamin D in terms of total cholesterol, LDL and triglyceride levels, HDL, VLDL, FBS and atherogenic index (LDL/HDL) (p=0.000).
Conclusion: The present results showed that there is a significant relationship between level 25-(OH) D and atherogenic index (LDL/HDL) and the incidence of metabolic syndrome.

Published: November 2021

The Online game is a technological product that is quite popular among adolescents. Violent characters in online games can affect the game players. Hurting the enemies in the games every day will gradually lead adolescents to think that hurting people is a fun and common thing to do. The adolescent delinquency cases in Yogyakarta occur every year, and the most frequent cases are klitih (maltreatment) and brawls. This study aims to discover the relationship between the level of addiction to violent online games and the intensity of violent behavior in adolescents. This study employed a quantitative method with a cross-sectional approach. Data were collected through Game Addiction Scale for Adolescent questionnaires by about the adolescents’ addiction to online games and violent behavior in adolescents. The respondents of the study were 96 adolescents, recruited using the Lemeshow formula. Data were analyzed using the Spearmen rho test. Results showed that 48 adolescents (50%) were addicted to online games at a moderate level. The majority of adolescents (44.8%) had a low intensity of violent behavior. The p-value was 0.000 (<0.005). The correlation value was 0.731, indicating a strong correlation between online gaming addiction and intensity of violent behavior, and the positive value suggests a unidirectional relationship. The level of online gaming addiction in adolescents in Yogyakarta is moderate. Online gaming addiction and violent behavior have a significant relationship with a strong correlation coefficient and a unidirectional relationship. Future researchers are suggested to add research variables to discover other factors contributing to violent behavior in adolescents.
