A Formal, Resource Consumption-Preserving Translation from Actors with Cooperative Scheduling to Haskell*
Authors: Albert Elvira , Bezirgiannis Nikolaos , de Boer Frank , Martin-Martin Enrique
Published: December 2020

We present a formal translation of a resource-aware extension of the Abstract Behavioral Specification (ABS) language to the functional language Haskell. ABS is an actor-based language tailored to the modeling of distributed systems. It combines asynchronous method calls with a suspend and resume mode of execution of the method invocations. To cater for the resulting cooperative scheduling of the method invocations of an actor, the translation exploits for the compilation of ABS methods Haskell functions with continuations. The main result of this article is a correctness proof of the translation by means of a simulation relation between a formal semantics of the source language and a high-level operational semantics of the target language, i.e., a subset of Haskell. We further prove that the resource consumption of an ABS program extended with a cost model is preserved over this translation, as we establish an equivalence of the cost of executing the ABS program and its corresponding Haskell-translation. Concretely, the resources consumed by the original ABS program and those consumed by the Haskell program are the same, considering a cost model. Consequently, the resource bounds automatically inferred for ABS programs extended with a cost model, using resource analysis tools, are sound resource bounds also for the translated Haskell programs. Our experimental evaluation confirms the resource preservation over a set of benchmarks featuring different asymptotic costs.
Simulation of financial risk spillover effect based on ARMA-GARCH and fuzzy calculation model
Authors: Wang Chong , Wei Yuesong
Published: December 2020

Convergence and spillover are the characteristics shown in the process of financial development. By verifying whether there is convergence and spillover in financial development within a certain region and between regions, the stage of financial development in the region can be more accurately judged. This paper combines the actual needs of financial analysis to construct a financial risk spillover effect model based on ARMA-GARCH and fuzzy calculation. The model uses ARMA-GARCH and fuzzy algorithm to verify the financial multiple risk factors. Moreover, in order to verify the effect of the model, this paper uses case data analysis to study the model effect and combines mathematical statistics to process the model data. The research results show that the model constructed in this paper has a certain effect, and the ARMA-GARCH model is suitable for analysis and research on financial risk spillover effects. At the same time, when the statistical distribution is used to fit its error distribution, the fitting and prediction effect of the model is better.
During COVID-19, which is more effective in work accident prevention behavior of healthcare professionals: Safety awareness or fatalism perception?
Authors: Ünal Özgün
Published: December 2020

BACKGROUND: As the pandemic process, COVID-19 has a serious occupational safety risk for healthcare professionals. Therefore, determining their health and safety perceptions and attitudes in the pandemic process is very important. This study aims to determine which is more effective in work accident prevention behavior: safety awareness and competencies of healthcare professionals or perception of fatalism. METHOD: For this purpose, a questionnaire was applied to 326 healthcare professionals. The questionnaire consists of four parts: (1) demographic information of the employees, (2) scale of preventing occupational accidents, (3) fatalism perception scale in occupational health and safety, and (4) security awareness and competency scale. Descriptive statistical methods, multiple regression and correlation analysis were used in the analysis of the data. RESULTS: It was determined that the participants’ safety awareness and competencies were at the high level and their fatalism perceptions were at the low level. The average of the responses given by the participants to the scale of preventing work accidents was above the middle level. According to the study, the safety awareness and competencies of health workers were found to be about three times more effective on the behavior of preventing work accidents than the perception of fatalism. CONCLUSION: In conclusion, it is important to recommend managers to take the step to increase the safety awareness and competencies of those working in their institutions.
The changed relations between the construction industry and occupational health services
Authors: Johansson Maria , Nygren Magnus , Berglund Leif
Published: December 2020

BACKGROUND: From the 1960s until the beginning of the 1990s, the construction industry in Sweden received support for health and safety issues from Bygghälsan, an Occupational Health Service (OHS) that targeted the construction industry. In the 1990s, a reorganization of the OHS changed the relations between the actors involved. OBJECTIVES: This study explores these changed relations between the construction industry and the “old” industry-specific Bygghälsan versus the relations with “new” external OHS. METHODS: Semi-structured interviews were conducted with 22 interviewees from the construction industry and individuals involved in OHS which were transcribed and analyzed. RESULTS: The results suggest that OHS have changed towards a more general character instead of tailor-made services which has had a negative effect on the relations. Further, Bygghälsan was perceived as being a part of the construction industry while contemporary OHS providers were perceived as outsiders which further complicates building trustful relations. CONCLUSIONS: The relation between the construction industry and Bygghälsan was perceived as better compared to the relations with the new companies providing external OHS. The main barrier to building better relations is the perception that contemporary OHS do not have the same knowledge about the construction industry as Bygghälsan.

Authors: Zomkowski Kamilla , Bergmann Anke , Sacomori Cinara , Dias Mirella , Sperandio Fabiana Flores
Published: December 2020

BACKGROUND: Breast cancer treatments lead to several comorbidities in the upper limbs, such as pain and stiffness, hindering physical functions and the return to work. OBJECTIVE: To explore the functionality and factors associated with work behaviour among manual and non-manual Brazilian workers who have recovered from breast cancer. METHODS: This is an observational cross-sectional study involving Brazilian breast cancer survivors. The sociodemographic, work, and clinical aspects were assessed through clinical records, upper limb disability, and human functionality obtained from 62 women. Multiple and univariate logistic regressions were used to identify the association of variables on return to work, p < 0.05. RESULTS: 56.5% of women did not return to work, the mean time for returning to work was 16 months (±15.21), absenteeism from work lasted 41 months (±34.58). Modified radical mastectomy (OR = 5.13, 95% CI = 1.35 to 18.66) and moderate-to-severe disability levels in the upper limbs (OR = 6.77, 95% CI = 1.86 to 24.92) were associated with not returning to work. The loss of productivity was higher among non-manual workers (21.5%) (p = 0.040). CONCLUSIONS: The rates of not returning to work after breast cancer treatment are high. Women who did not return to work presented higher levels of disability.

Published: December 2020

BACKGROUND: Researchers suggest that physiotherapists are highly exposed to both the physical and the mental strains. OBJECTIVE: The aim of this study was to assess mood and the level of stress as well as a sense of coherence among future physiotherapists studying at the Department of Physiotherapy. METHODS: The study included 249 students, 181 women and 68 men. The Beck Depression Inventory (BDI), the Sense of Coherence Questionnaire (SOC-29) and the Perceived Stress Questionnaire (PSQ) were used. RESULTS: The examined group had an average level of sense of coherence and a low level of stress. One out of four students exhibited mood disorders. The factors associated with the prevalence of mood disorders among studied students were as follows: female (gender), lack of regular physical activity, poor financial situation, lack of friend to talk to in case of problems, dissatisfaction with the chosen field of study, and being inadequately prepared to work as a physiotherapist. CONCLUSIONS: The results of the study indicate an increased prevalence of mood disorders among students of physiotherapy. It is suggested that this situation may require the implementation of effective psychoprophylactic activities during the course of studies and broadly understood education about the psychophysical wellbeing of students, especially as they will work in an environment that requires high resistance to stress and support for other people in a crisis situation.
Upper extremity strength: Normative reference data among uninjured employees
Authors: Harbin Gary , Leyh Christian , Harbin Alexander
Published: December 2020

BACKGROUND: Extremity strength testing is used to determine the ability of industrial employees to perform a physically demanding occupation safely, evaluate post-injury impairment, and monitor return to function after injury. There is an unmet clinical need for a robust and granular source of normative reference values to serve as a resource for baseline data on upper extremity isometric strength. OBJECTIVE: Develop normative reference data for upper extremity strength among industrial employees and investigate associations between strength and physical job demands. METHODS: Upper extremity strength data from 107,102 industrial employees were collected post-hire. In this study, isometric tests for pinch; hand grip; wrist pronation and supination; and flexion of the wrist, elbow, and shoulder strength were retrospectively analyzed in relationship to sex, age, and job level. Associations between strength scores and five levels of work, defined the United States Department of Labor’s Dictionary of Occupational Titles by level of physical difficulty (1–5), were determined. RESULTS: Higher strength scores were positively associated with more physically demanding job levels (P < 0.001), and there was a progressive increase in strength scores with increased physical job demands for both sexes (P = 0.0002). All strength scores differed significantly by decade of age (P < 0.001). All scores except for pinch strength demonstrated a moderate or high positive correlation with job level (r≥0.50). CONCLUSIONS: The normative reference upper extremity strength data collected in this study for industrial employees may be useful for evaluating rehabilitation and recovery following injury or illness. In order to utilize normalized strength data as a post-injury reference, it is important to consider job level in addition to age and sex, as these variables are highly correlated with baseline upper extremity strength.

This study suggests the English teachers to try adapting JAM as a mean to help their students scaffold the speaking fluency.
REDEFINING AND REPOSITIONING ACTION RESEARCH IN SCHOOL PRACTICE
Authors: Retnowati Nanik
Published: December 2020

Classroom action research is undoubtedly important to be implemented by teachers. Many experts on education have provided enormous rationale bases for the benefits of conducting action research for quality education. However, there have not been many teachers performing it with many different reasons. It is important for any parties who are concerned on quality education to find out teachers’ reasons of not conducting action research. The data could be used to formulate any strategies to promote action research in school practice. However, this paper suggests that finding out why teachers perform action research is not less important. Teachers’ motives of performing action research cannot be separated from the values proposed by idealized concept of action research itself.  Thus it is important to examine closely whether teachers’ perspectives meet with the intended benefits as proposed theoretically.  The findings are useful to give an insight on whether action research needs to be redefined and repositioned in educational practice.
Get Americanized? The presidential election in Slovakia
Authors: Žúborová Viera
Published: December 2020

„Americanisation” in political campaign assumes on the one hand that all changes, techniques and campaign tools were directly taken from the United States. On the other hand, it also reflects general developments in political policy, media and society (modernization). The main objective of this article is to examine these trends by using the example of new democracy – the Slovak Republic? The paper therefore identifies the main characteristics of the process, but also to set an adequate methodological framework and try to explore it in the Slovak environment, specifically in the context of the presidential elections of 2009 and 2014.
An Action Research Study on Teaching the Landform Concepts in a Fifth Grade Social Studies Course
Authors: İNEL Yusuf , URHAN Emrah
Published: December 2020

This study aims to find out the effect of activities and practices on concept education to help carry out activities to teach these concepts more effectively and permanently, and determine student preconceptions about the concepts related to the landforms in the 5th-grade social studies curriculum in the learning subdomain called “People, Places and Environments.” It was conducted as an action research study, employing a qualitative research design. The participants of the study were 16 fifth graders who were studying at a state secondary school in Bekilli District of the province of Denizli, Turkey. Mind maps, worksheet activities, models and mock-up, focus group interviews and field notes were used as the data collection tools, concept development tools, and process support tools. Collected in four class hours, the data were subjected to statement-based content analysis, and then compared with the criteria developed for the related concept and converted into findings and conclusions. The findings indicate that the student group has a partial preliminary knowledge and perception of the distinctive landforms they see around them. However, the student group's preliminary knowledge and perception of the landforms they do not observe around them is insufficient. The results obtained at the end of the instructional intervention process indicate that the student group is confused about the definitions of the bay, gulf, cape, peninsula, island, strait, and ocean. With the activities implemented after the additional action plan, the student group made progress by effectively learning the basic and sub-dimensional landforms they were confused about. The student group found it useful to carry out mind maps and application activities and achieved effective learning with models and mock-ups. Based on research result, use of sightseeing –observation techniques can be recommended to social studies teachers.

Published: December 2020

Background: Chronic otitis media (COM) is the long-standing infection of a part or whole of middle ear cleft characterized by ear discharge & perforation. The most common presenting symptoms are ear discharge, mild to severe hearing loss, sometimes tinnitus even vertigo. Treatment of COM is mainly operative. The treatment of inactive mucosal variety of COM is Type 1 tympanoplasty. It can be done by microscopic or endoscopic technique. Both methods have some merits and demerits.
Objectives: Aim of the study was to compare the surgical outcomes between endoscopic and microscopic type 1 tympanoplasty.
Methods: This study was carried out in the Department of Otolaryngology–Head & Neck surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka from March 2017 to June 2019 and 60 (30 in each group) patient were included in the study. All patients underwent type 1 tympanoplasty. In Group A endoscopic tympanoplasty cases and in Group B microscopic tympanoplasty cases were placed. Operation duration, post-operative pain, postoperative hearing status, graft uptake was compared in two groups.
Results: There were no significant difference of graft uptake and hearing gain (>0.05). But endoscopic operative time and post-operative pain were less than microscopic group (<0.05).
Conclusion: Through endoscopic tympanoplasty is a newer approach and it has some limitations. As endoscopic tympanoplasty requires less time, less pain with similar graft uptake and audiological success. It can be adopted as an alternative method of tympanoplasty.

Published: December 2020

Background: Chronic suppurative otitis media (CSOM) is an inflammatory process in the middle ear cleft. When there is attic or marginal perforation it is called the atticoantral variety of COSM which is manifested as foul smelling aural discharge and hearing impairment. In Bangladesh, chronic suppurative otitis media (CSOM) is a common disease in clinical practice.
Objective: The aim of this study was to find out the clinical presentation of atticoantral chronic suppurative otitis media (CSOM) in defence personnel and their families.
Methods: A retrospective study was carried out in the Department of ENT and Head-Neck Surgery, Combined Military Hospital (CMH), Dhaka from 01 April 2017 to 31 December 2019.Forty seven patients of Atticoantral variety of CSOM were included by matching inclusion and exclusion criteria.
Results: Majority of the patients presented in the second and third decade of life(11-20 years: 29.79%, 21-30 years: 44.68%). All the patients belonged to the soldiers and their families. The maximum numbers of patients were from rural area(51.06%), completed only primary education (48.94%). Most of them lived in a kutcha building. Almost all the patients presented with multiple symptoms. Discharge from ear(s) (100%), and hearing impairment (82.97%) were the leading features. Only (2.14%) had extracranial complication and there was no intracranial complication. Most of the patients were having unilateral atticoantral CSOM, in the right side (61.70%), left side (36.17%) and only one (2.12%) had bilateral involvement. Audiometric tests were done in 100% of the patients and found; mild deafness (19.14%), moderate deafness (78.72%) and moderately severe deafness (2.14%).
Conclusion: The frequency of chronic suppurative otitis media is higher in the younger age group and lacking of education. By increasing health awareness of the general people and early diagnosis of atticoantral CSOM and timely surgical intervention may be helpful to eradicate the disease and prevent complications.

Authors: Çitak Burcu Yilmaz , Dural Hüseyin
Published: December 2020

The present study was designed to analyse the anatomy of the vegetative and reproductive parts of Turkish Iberis species from a systematic point of view. Samples of leaves, stems, roots, fruits, and seeds of each species were collected, fixed, and processed according to the paraffin method for light microscopy. The numerical analysis derived from 11 anatomical characteristics showed that the number and dimensions of vessels in the root, presence of aerenchyma in the leaf, number and dimensions of palisade parenchyma, and mesophyll type were useful for grouping the Iberis taxa. The testa was composed of four layers: the epidermis, subepidermis, compact tissue, and parenchyma. The testa thickness was a significant character to distinguish the investigated Iberis species. In this study, the traditional classification of Turkish Iberis species was mostly congruent with the dendrogram generated vegetative anatomical properties.

Published: December 2020

Brassica tournefortii Gouan. (family Brassicaceae) is one of the five species in the Egyptian flora. Its populations showed notable morpho-plasticity with taxonomic debates, which were not yet resolved. The current study was carried out to assess the species morpho-plasticity and its molecular identity based on ISSR. The study was applied to 27 herbarium and fresh populations, representing all the species distribution ranges in Egypt. The taxonomic revision included 70 morphological characters, revealed five distinct Forms (1-5), radical leaf, and fruit provided the major distinguishable traits among the studied 70 morphological characters based on them the morphologic key is provided to delimit these forms. The pollen grain features using SEM are a pioneer at the infra-specific level, two shapes observed the subprolate (Forms 1& 3) and prolate (Forms 2, 4 & 5). Furthermore, the exine micro-features possess taxonomic value at the infraspecific level. The cluster analysis based on ISSR data revealed two clusters congruent to those developed by morphological and pollen traits. The ISSR results indicated that the species morpho-plasticity is genetically controlled. The study highlights the importance of the multidisciplinary approach to assess the taxonomic identity at the infra-specific level, for the auto-taxonomy of morpho-plastic species.

Published: December 2020

Kullanılabilirliği yeterli olmayan bir biyokabin altında yapılan ve biyolojik ajan riski taşıyan uygulamanın risk düzeyinin belirlenmesi önemli bir problemdir. Bu probleme cevap bulmak amacıyla bu çalışmada biyokabinlerin biyolojik risk analizi yoluyla kullanılabilirliği değerlendirilmiştir. Bu kapsamda biyoloji eğitimi veren bir fakültenin mikrobiyoloji laboratuvarındaki sınıf 1 ve sınıf 2 biyokabinlerin kullanılabilirlik testleri ve bir deney çalışması ile besiyerlerine koliform bakteri pasajı yapılmıştır. Sonrasında, test ve deney bulguları neticesinde mevcut yönetsel ve mühendislik önlemleri tanımlanmıştır. Sınıf 1 biyokabin altında yapılan uygulamanın 4x3 matris modeli ile biyolojik risk analizi yapılmıştır. Biyolojik risk analizinde, mevcut önlemler ve üretilen bakterilerin risk grubu dikkate alınarak ortaya çıkabilecek risk düzeyi tespit edilmiştir. Uygulamanın risk düzeyi ‘’orta’’ seviyede bulunmuştur. Bu sonuç biyokabinin kullanılabilirliğinin yeterli olmadığını ortaya koymuştur. Biyokabin işlevini istenilen düzeyde yerine getirememekte ve biyokabin altında uygulama yapılmasına rağmen kullanıcılar biyolojik risklere maruz kalmaktadır. Bu nedenle biyokabinlerin kullanılabilirliğini artırmak için ek önlemlerin alınması gerekmektedir. Ek önlemler kapsamında standardizasyon, bakım, temizlik, performans testleri ve sertifikasyon çalışmalar önerilmiştir.

Laccases are part of the family of ligninolytic enzymes and have played essential roles in several biological filamentous fungi processes, including fruiting body formation and lignin degradation. This study aimed to identify and characterize laccase genes in silico of several basidiomycete strains. The applied guaiacol oxidation test allowed the selection of seven out of 11 strains with ligninase activity, which were used for DNA extraction and amplification of the copper-binding region. A single amplicon of approximately 450 bp, was produced by all selected strains and they were further sequenced. Sequence analysis has suggested the presence of a new subdivision of the laccase genes. Clustering analysis confirmed the existence of two groups: cluster A with six strains and singleton B with U8-11 strain. The structural predictions of the U8-11 protein were dissimilar compared to other proteins described in our study due to the absence of the ALAVIN motif and, therefore, the U8-11 amino acid sequence was separated in a different cluster.

Diarrhea, which is a gastrointestinal disease, has as its main characteristic the rapid passage of gastric contents through the intestine, which leads to the loss of water and electrolytes and consequent dehydration. The most common fluid replacement is the use of oral rehydration solution (ORS) together with the use of the drug loperamide. However, the use of this medication can cause severe bacteremia followed by sepsis and even death. Currently, there is no effective pharmacological treatment for diarrhea, therefore, it is noted the importance of seeking new therapeutic targets for the treatment of this disease. Thus, the aim of the present study was to conduct a research on the biological activities already described for Diminazene Aceturate with a special focus on antidiarrheal agents. For this, a survey was carried out, through patent filing searches, in the USPTO, EPO, WIPO and INPI databases, using keywords and Boolean operators. Thus, it was found in the international patent databases the number of documents referring to the use of Diminazene Aceturate in several areas, mainly in the pharmaceutical industry, but with a relatively low number of documents regarding the description of possible antidiarrheal action of the compound under study , which reinforces the innovative character of research involving the use of Diminazene Aceturate as an antidiarrheal agent.

The article considers challenges and consequences of introducing a three-level model of transfer pricing documentation in Ukraine. The purpose of study is to assess the state of regulatory support for implementation of Step 13 of the BEPS Action Plan and to identify institutional measures for further implementation of three-tiered documentation on transfer pricing, taking into account the requirements of the Organization for Economic Co-operation and Development (OECD). The authors analyzed the state of accession of countries all over the world to the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting, in order to counteract the erosion of the tax base and the withdrawal of profits from taxation of the OECD, ratified by the Law of Ukraine dated 28.02.2019 No 2692-VIII. Analysis of national legislation to take into account the requirements of the BEPS Action Plan and the experience of cooperation of the Government of Ukraine with international tax organizations allowed to scientifically substantiate the directions of improvement of national regulations on tax issues and to determine methodology for application of innovative reporting form in the context of further implementation of BEPS Action Plan. It is identified that implementation of a three-tiered reporting model for transfer pricing in Ukraine is at the beginning of the development, in particular legislation. The authors emphasize the importance of counteracting information asymmetry by ensuring the unification of terminology and quality of the database for innovative reporting preparation, in particular, for global documentation on transfer pricing, transfer pricing documentation and Country-by-Country reporting of multinational entities. Within the study it was proved that the organization of the reporting process at all levels of the Three-Level Model of transfer pricing documentation (hereinafter the Three-Level Model) should be aimed at preparing reports that contain reliable information with the maximum exclusion of duplication.

The presence of a stable coordinate basis, fixed on the ground by a network of geodetic points is one of the key factors in the single geospace successful formation. Current state of the Novosibirsk region network analysis has shown that a significant amount of outdoor sings points were lost due to the citizens’ economical activities and a number of other factors as well. That has caused significant difficulties in using such points. The purpose of this paper is to study state geodetic network, state levelling network and state gravimetric network points’ security regime. The scientific significance of this paper is seen as a way to determine the role of the specified security zones in the special territory usage conditions system, as well as the classification of such zones. The practical significance of the article is to forecast possible ways of improving state geodetic network, state levelling network and state gravimetric network points’ security regime. The research methodology includes the current security zone regime state analysis as well as forecasting the possible way of its improvement in the future. The main conclusions of this paper indicate that geoinformation systems play a key role in preventing damage and loss of objects which provide human activity on the Russian territory: zones with special conditions are created, which include state geodetic network, state leveling network and state gravimetric network protection zones. Timely provision of their security can guarantee the smooth operation of the entire state as a whole. To prevent of state geodetic network points’ further loss, it is necessary to create a united information resource (geoportal), which would reflect the existing and projected security zones using 3D representation.

The purpose of this article is to select and substantiate the criteria for protective construction monitoring of main pipelines. Main pipelines are constantly exposed to influences of external and internal factors. Special protective constructions are being raised to ensure the continuous operation of the pipelines. The main goal of creating protective constructions is to minimize economic losses and preserve the environmental characteristics of the facility. All existing protective constructions can be divided into two large groups: earth work and engineering constructions. Each of these groups includes different types of the constructions. All of them are designed to ensure safety of main pipelines from a certain natural phenomenon. It is also necessary to ensure constant monitoring of their geometric state regardless the protective construction type. Various data can be used for monitoring, among which the Earth remote sensing data perform a special role. One of the main issues in the construction monitoring is the explanation of the arising measurement errors. This requires knowledge of complex precision calculations theory. It is also necessary to take into account that a visual inspection of the construction defects is imperative in any calculations. A classification of protective constructions is given. The base of the accuracy calculation theory that is necessary to substantiate the errors in the protective construction monitoring is discussed. The main accuracy standards based on this theory are highlighted. The results of the performed analysis are the numerical values of the accuracy criteria for various protective construction types.

Objective: Proteasomal system is the primary protein degradation mechanism and important for cellular homeostasis. On the other hand, increased proteasome activity protects cancer cells from cell death. The objective of this preliminary study was to determine the response of the proteasomal system to oxidative stress in human cancer cell lines including K562 chronic myelogenous leukemia, U251 glioblastoma, DU145 prostate cancer, HepG2C3A hepatoma, and MCF7 breast cancer.
Methods: Cells were exposed to hydrogen peroxide (H2O2) as a stressor. 20S and 26S proteasome activities and K48-linked protein ubiquitination levels were determined immediately and 3 hours after exposure.
Results: As an immediate response, 20S proteasome activities decreased in only K562 and U251 cells and 20S+26S proteasome activities decreased only in K562 cells. Following 3h of incubation, all cells showed a significant decrease in both 20S and 20S+26S proteasome activities. K48-linked protein ubiquitination levels increased immediately in K562 and DU145 cells. After 3h of incubation, ubiquitination levels increased in all cell lines except MCF7 cells.
Conclusion: The difference in the response of the proteasomal system to stress could be the reason for differential adaptation to oxidative
stress in different cancer types.
