Photocatalytic Treatment of An Actual Confectionery Wastewater Using Ag/TiO2/Fe2O3: Optimization of Photocatalytic Reactions Using Surface Response Methodology.
Authors: Lin Yi-Ping , Mehrvar Mehrab
Published: August 2021

Titanium dioxide (TiO2) photocatalysis is one of the most commonly studied advanced oxidation processes (AOPs) for the mineralization of deleterious and recalcitrant compounds present in wastewater as it is stable, inexpensive, and effective. Out of all, doping with metal and non-metals, and the heterojunction with another semiconductor were proven to be efficient methods in enhancing the degradation of organic pollutants under ultraviolet (UV) and visible light. However, complex degradation processes in the treatment of an actual wastewater are difficult to model and optimize. In the present study, the application of a modified photocatalyst, Ag/TiO2/Fe2O3, for the degradation of an actual confectionery wastewater was investigated. Factorial studies and statistical design of experiments using the Box-Behnken method along with response surface methodology (RSM) were employed to identify the individual and cross-factor effects of independent parameters, including light wavelength (nm), photocatalyst concentration (g/L), initial pH, and initial total organic carbon (TOC) concentration (g/L). The maximum TOC removal at optimum conditions of light wavelength (254 nm), pH (4.68), photocatalyst dosage (480 mg/L), and initial TOC concentration (11,126.5 mg/L) was determined through the numerical optimization method (9.78%) and validated with experimental data (9.42%). Finally, the first-order rate constant with respect to TOC was found to be 0.0005 min−1 with a residual value of 0.998.

History and Evolution of the Environmental Management System in Brazil
Authors: Fernandes Valdir , Andreoli Cleverson Vitorio , Bruna Gilda Collet , Philippi Jr Arlindo
Published: August 2021

The idea of sustainable development emerges first as a socio-political movement, from a series of questions and concerns that have arisen at the international level, related to the contamination of natural environments and human beings, a result of industrial activities. From these concerns, a series of events and movements caused significant changes in international and national policies, leading to the construction of a significant legal framework and institutional apparatus, never seen in any other theme. The establishment of environmental management systems in most countries was a direct reflection of an international agenda launched during the Stockholm Conference, in 1972, which was continued with several other conferences and protocols, such as Rio-92, Rio+20, Kyoto Protocol, Paris Agreement, among others, that have consolidated an international environmental agenda over the past 50 years. In Brazil, this process generated direct reflexes with the construction of a significant legal framework and institutional apparatus. In this article, we describe this process, an important part of both the world’s and the Brazilian environmental history until 2014.

“I see what I have been dreading”:Witnessing Food and Violence in Waiting for the Barbarians and In the Heart of the Country
Authors: Sinha Nimisha
Published: August 2021

This paper explores the presence of a food and consumption related gaze in J.M. Coetzee's Waiting for the Barbarians (1980) and In the Heart of the Country (1977). Through the phenomenon of food witnessing, I argue that the food-related gaze is tied with the narrative frame through which torture and violence is witnessed and recorded. The act of watching people eat or other metaphors of food (largely examined throught the idea of 'food witnessing') serve as a way to identify, observe and obliterate the Other.
The Parasite of Society: Food and Class Studies in Bong Joon-ho’s Film Parasite
Authors: Turner Emily
Published: August 2021

The role that food plays in film typically has more meaning than a viewer might realize at first. Often viewers watch movies for entertainment without analyzing the context that the food in each scene provides to the richness of the plot. For example, Bong Joon-ho’s 2019 award-winning film Parasite thrills its audience while warning them about the dangers of capitalism and class disparity. Despite the popularity of this film, the aspect of food was quietly forgotten even though it enhances the movie’s theme. Bong intentionally placed food in this film to signify class status which further divides the Park and Kim families. While this is a critically acclaimed film, there is not much scholarship devoted to food studies concerning social class in Parasite; therefore, I am drawing upon movie reviews as well as scholarly work about food in media. In doing this, I have studied Parasite through lenses of socio-economic theory as well as food theory to analyze how food is used in the film. Food involves more than simply preparing ingredients and consuming the final product, especially when used in media and popular culture: it often provides deeper meaning that must be examined in order to know what is truly being said. In the film Parasite, food is the vehicle that Bong uses to signify social status, and furthermore, it signals class disparities between the wealthy and impoverished. Beyond the film, Bong uses food to warn his audience how class inequality could be the downfall, the parasite, of society.

How Successful was Large-scale Social Restrictions Policy in Suppressing COVID-19
Authors: Marchianti Ancah Caesarina Novi , Purbyanto Eko
Published: August 2021

Large-scale Social Restrictions (LSR) was the Indonesian government's primary instrument to break the chain of coronavirus or COVID-19 transmission at the early phase of the pandemic. LSR implementation such as school and workplace closure, restrictions on religious activities, and or restrictions on activities on public premises or facilities. This study aims to investigate the effect of LSR policy on COVID-19 developments in Indonesia. This study was a cross-sectional study with a total population of 99,077,313 people from three provinces in Indonesia. This research analyzed the LSR policy implemented in the entire province or partially as an exposure and the development of Covid-19 as an outcome. The outcome was measured by doubling the times needed for new cases. Data were taken from secondary source namely from the COVID-19 task force report that has been announced publicly. The unpaired two-tailed Student’s t-test was used as statistical analysis of the secondary data. The results showed a significant impact (p<0.05) when comparing the province with full LSR policy with those implementing the LSR policy in some of their selected cities. The LSR policy of total province seems effective to suppress COVID-19 development as indicated by a more rapid and considerable increase in the doubling time of new cases following the implementation of LSR as early as possible in the provinces implementing LSR for their entire region than in the compared provinces. It can be concluded that LSR policy has a significant effect on COVID-19 development in Indonesia as indicated by a significant difference in the doubling time of COVID-19 new cases. Each province may have different times of the beginning and end of the COVID-19 epidemic; therefore, each province needs to design their coping strategy based on their particular condition.

Published: August 2021

The COVID-19 pandemic has a serious impact on people’s lives, including teachers. The need to continue the learning process during a pandemic has caused teachers and students to encounter many problems, including limited internet access in remote areas. Landang Elementary School (SDN 19 Landang) in Bantaeng Regency is one of the elementary schools in South Sulawesi located in the remote area facing the aforementioned problem. The teachers are forced to teach the students by home visit to provide learning activities. The condition in which people must keep their distance from each other to avoid the spread of COVID-19 virus yields stress. The study aims to analyze the factors that cause stress among elementary school teachers. This cross-sectional survey method involved 47 respondents using Perceived Stress Scale (PSS) on Google Form platform as the instruments. Age and teaching duration had significant association with the stress level among teachers after analysis using chi square test.

Authors: Hromova Hanna
Published: August 2021

Ставлення до невизначеності та неоднозначності вимірюється за допомогою багатьохопитувальників, адже розуміння конструкта і структури (ін)толерантності до невизначеностіваріюється. На сьогодні жоден із тестів, за допомогою яких вивчається трансдіагностичнамодель розвитку афективних розладів, не був перекладений на українську мову. Щобзаповнити цю прогалину, було зроблено переклад та адаптацію тесту «Шкала інтолерантностідо невизначеності» Н. Карлетона (IUS-12). Методологія: 226 студентів заповнилиопитувальники IUS-12, MSTAT-1, тести депресії і тривоги А. Бека, інтегративний тесттривожності А. Бізюка. Для перевірки дво- та біфакторної структури опитувальникапроведено конфірматорний факторний аналіз. За допомогою кореляційного аналізуперевірено конвергентну і дивергентну валідність тесту. Результати адаптації тесту свідчатьпро те, що біфакторна модель структури опитувальника краще описує емпіричні дані; тестмає досить високий коефіцієнт α-Кронбаха (0.81). Конвергентну валідність підтвердженокореляційними зв’язками із ситуативною та особистісною тривожністю, депресією як длязагального бала тесту IUS-12, так і для субшкал. Тест «Шкала інтолерантності доневизначеності» Н. Карлетона має обернений зв’язок з результатами опитувальника «Шкалазагальної толерантності до невизначеності» Д. Маклейна, що підтверджує дивергентнувалідність. Застосування тесту на вибірці військових (n=137) підтвердило його надійність тавідтворюваність результатів аналогічних досліджень. Є певні обмеження: адаптація теступроводилася на студентах, тому необхідно перевірити дані на клінічній вибірці; не завершеноперевірку надійності тесту методом «тест-ретест». Висновки: українська версія тесту «Шкалаінтолерантності до невизначеності» Н. Карлетона має достатній рівень надійності, перевіренувалідність і відповідає біфакторній структурі. Це перший із найбільш поширених сучаснихтестів для вимірювання рівня інтолерантності до невизначеності, що пройшов процедуруперекладу українською мовою та подальшої адаптації і відповідає всім психометричнимвимогам. Тест можна використовувати для подальшого дослідження толерант-ності/інтолерантності до невизначеності, вивчення суміжних конструктів та кроскультурноїспецифіки ставлення до невизначеності, що є особливо актуальним завданням в умовахтривалої пандемії.
The Demographic and Clinical Practice Profile of Australian Remote and Industrial Paramedics: Findings from a Workforce Survey
Authors: Acker Joseph James , Johnston Tania
Published: August 2021

Introduction

A large workforce is employed in remote environments in the Australian mining and fuel sectors. Whereas paramedics are increasingly assuming roles as healthcare providers in these locations, little is known about industrial paramedic practice. The aim of this exploratory study was to better understand the demographics, education, clinical practice and work environment of the Australian paramedic workforce in remote and industrial settings to inform future research and education for the emerging specialty.

Methods

Web-based respondent driven network sampling was used to recruit remote and industrial paramedics in this cross-sectional descriptive study. A self-administered questionnaire elicited responses (n=111) about participant demographics, work environment, initial and continuing education, and clinical scope of practice.

Results

Paramedic participants working in remote and industrial settings are predominately male (86.5%) with the majority aged 35 to 44 years (38.7%). Their job titles range widely and include paramedic, intensive care paramedic, industrial, mine and offshore paramedics. Participants report an average of 15.4 years of total healthcare experience and working in the remote or industrial health sector for a mean of 7.1 years, primarily in Western Australia (34.2%). These paramedics often engage in continuing education, with 45% studying at a vocational or tertiary institution at the time of the survey. Most respondents (63.9%) describe their employment as directly or indirectly related to the natural resource sector and 75.7% have experience in remote settings such as camps, mining sites, offshore platforms, vessels or small communities. Most practitioners (59.5%) work in a full-time capacity and can perform core paramedic skills including intravenous cannulation, 12-lead electrocardiogram interpretation, chest needle decompression and restricted drug administration. Additionally, more than 40% of those actively working in the sector report having endotracheal intubation and intraosseous access in their scope of practice. They also administer immunisations, antibiotics and other prescription medications, manage chronic diseases, and perform low acuity skills typically included in a community paramedic role.

Conclusion

This workforce survey is the first of its kind designed to gain a broader understanding of the paramedic practitioners who work in remote and industrial settings and the characteristics of their work environment. Key areas highlighted by this study serve to inform professional regulators, educators and employers with respect to the skills that remote and industrial paramedics perform and the education that is required to support the evolving specialised practice.
LEARNING STYLE AS A FACTOR INFLUENCING THE EFFECTIVENESS OF THE INQUIRY-BASED SCIENCE EDUCATION AT LOWER SECONDARY SCHOOLS
Authors: Škoda Jiří , Doulík Pavel , Bílek Martin , Šimonová Ivana
Published: August 2021

The IBSE has become a rather frequently applied strategy of directing learning activities in teaching science subjects. However, results of the IBSE effectiveness are not clear. A more detailed analysis is required which will reflect learners´ individual characteristics. Therefore, the main aim of this research is to discover what the effectiveness of IBSE reflecting individual learning style is. The learning style categorization followed the Honey and Mumford´s variation on the Kolb´s system. The IBSE effectiveness was detected by the didactic test consisting of 15 PISA-style tasks. The research was conducted in the sample of 332 learners who were exposed to IBSE for five months. Their knowledge was tested before, immediately after and four months after the IBSE approach was applied in lessons. The collected data were processed by ANOVA and Tukey HSD test. The results show that the highest short-term results were reached with learners preferring concrete sensing; the highest long-term results were reached with those of active processing of information. This finding might be caused by better use of metacognition and acquiring such individual metacognitive strategies which learners apply at utilization of information. Further on, the IBSE should focus on mechanisms of fixing the acquired knowledge. Key words: inquiry-based science education, learning styles, educational practice, quantitative research, identification of learning results.

Authors: Siew Nyet Moi , Mapeala Ruslan
Published: August 2021

This research was conducted to evaluate the effects of Problem-based Learning (PBL) with Thinking Maps (TM) teaching method (PBL-TM) on Fifth Graders’ science critical thinking. The critical thinking skills evaluated were Comparing and Contrasting, Sequencing, and Identifying Cause and Effect in physical science. A quasi-experimental pre-test and post-test control group design was employed in the research. The sample consisted of 270 Fifth Graders (age 11 years old) from three primary schools in Tawau, Sabah, Malaysia who were all randomly selected and assigned to PBL-TM (n=90), PBL (n=90), and Conventional Problem Solving (CPS) (n=90) teaching groups. The 30-item Test of Science Critical Thinking was used as the pre-test and post-test. The three thinking maps used were Double Bubble Maps, Flow Maps, and Multi-Flow Maps. A MANCOVA was conducted on the post-test scores with students’ pre-test scores as the covariates. The result indicated that students in the PBL-TM group significantly outperformed their counterparts in the PBL group who, in turn, significantly outperformed their counterparts in the CPS group in Comparing and Contrasting, Sequencing, and Identifying Cause and Effect. The findings suggest that thinking maps, which were explicitly infused into problem-based learning is effective in promoting critical thinking among Fifth Graders in physical science lessons.

RUNNING DETAILS ON THE TWO MOVEMENTS IN THE INTELLECTUAL HISTORY OF SCIENCE AND IDEAS
Authors: Pisano Raffaele
Published: August 2021

A long tradition concerning the causes of the planetary movements existed as to the movements on the earth: the so called problem de motu locali. Starting from late middle Ages many criticisms were carried out against the Aristotelian doctrine of natural and violent motions. A well accredited and historically coherent theory to explain the movement and the change of movement was the medieval theory of impetus substantially developed by Jean Buridan (ca. 1300–ca. 1360) and by Nicolas d’Oresme (1320? 1325?–1382) on the basis of ideas that came back to John Philoponus (490–570).

Published: August 2021

The revelation of misconceptions contributes to better education, especially when that information is described in a specific field of science. Additionally, genetics is one of very problematic topics, and misconceptions appear there frequently as there are difficult interconnections among them. The main aim of the study was to explore high school students´ misconceptions about basic genetics concepts. Moreover the influence of gender was also examined. Respondents were 102 Czech high school students of two high schools. Research tool was test containing 15 two tier questions concerning about basic genetics concepts like chromosome, DNA, allele and gene. Reliability was determined with the use of Cronbach’s alpha coefficient. The result of Kolmogor-Smirnov test allowed to use parametric statistical methods. The data were analysed by the using of descriptive statistical methods (mean score) and inferential statistical methods (ANOVA). Concept ‘DNA’ was determined as the most problematic one for students, contrarily concept ‘allele’ was the simplest one. It was found that high school students do not understand selected basic genetic concepts. In addition, students do not interconnect genetic concepts within one complex system of knowledge, they also do not realise structure and hierarchy of these concepts. Key words: basic genetics concepts, misconceptions, genetics learning, high school students.
SCIENTIFIC RESEARCH ACTIVITY OF STUDENTS PRE-SERVICE TEACHERS OF SCIENCES AT UNIVERSITY: SIGNIFICANCE, READINESS, EFFECTIVENESS AND CAREER ASPECTS
Authors: Lamanauskas Vincentas , Augienė Dalia
Published: August 2021

Scientific research activity (SRA) of the future nature subject teachers during university studies is a significant their professionality / skilfulness component. Teacher research activity at school and education quality improvement are directly related. On the other hand, teacher as a researcher (research) competence is formed not only during studies at university or performing pedagogical practices, but also during continual professional improvement activities, as for example, reflexive research. It is obvious, that learners’ scientific research activity is one of the main activity directions in natural science education process. Such activity effectiveness, and also natural science education quality for the most part guarantees properly prepared teacher.
A qualitative research was performed, in which 84 two Lithuanian university bachelor and master study programme students participated. The main research aim is to analyse SRA significance to teacher profession, contribution to professional readiness, and also to evaluate study process favourableness to scientist (researcher) career choice and personal student readiness for SRA. Data analysis was carried out applying content analysis method.
It has been stated, that the biggest part of respondents relate SRA with professional improvement, and essential such activity contribution is professional readiness improvement (knowledge acquisition, experience and competence development). It has been fixed, that study process is partly favourable, however unsuitable conditions, teachers’ lack of interest and unfocused orientation to career hinder its improvement. Regardless of the fact that 50 % of research participants evaluated their personal readiness to participate in SRA as improper, still the attitude to researcher career remains positive.
Key words: qualitative research, scientific research activity (SRA), teacher education, university students.

Published: August 2021

Neurodevelopmental disorders (NDD) are public health burden worldwide. NDD causes disabilities and reduces the quality of life. Perinatal factors like maternal age, stress, maternal physical illnesses, birth complications, preterm birth, low birth weight and neonatal infections are the important risk factors for NDD. The objectives of the study were to determine the proportion of perinatal factors among children with neurodevelopmental disorders attending tertiary care hospitals in Dhaka city. This was a cross-sectional study conducted in outpatient department of National Institute of Mental Health (NIMH), Dhaka and Institute of Paediatric Neurodisorder and Autism (IPNA), Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2017 to July 2018. Among 115 children with NDD aged 0-17 years satisfying inclusion and exclusion criteria who were conveniently selected as sample. After diagnosing NDD using DSM- 5 criteria by psychiatrists and paediatric neurologists, a semi structured questionnaire was applied by researcher herself that included socio-demographic and perinatal factors as well. Results showed that majority of the respondents (29.6%) were 5-8 years with male predominance (78.3%). The most common perinatal factors were maternal factors like maternal stress (68.7%), maternal physical illness (66.1 %), inadequate food/rest intake (53.9%) and inadequate weight gain during pregnancy (50.4%). Fetal and neonatal factors like birth complication (82.6%), preterm birth (80%), low birth weight (75.6%), neonatal illness (69.6%) and birth asphyxia (61.7%). Most common neonatal illness were pneumonia (30.0 %) followed by neonatal Jaundice (20%). Early identification of possible perinatal factors and providing safe perinatal period can give a positive impact in prevention of NDD in children.

Coronary angiography is still the ‘gold standard’ in assessing the severity of stenotic lesions of the coronary arteries in the catheter laboratory. However, it is often difficult to identify the hemodynamic significance of one or another coronary artery stenosis, which is especially difficult in the case of borderline lesions with a coronary artery stenosis of 40–70 % according to angiography. It is important to note that the results of performed PCI are still largely assessed only on the basis of control angiographic data. This is due to the fact that the largest difference between angiography and FFR is in the intermediate range, and in general there is much less variation between angiography and fractional blood flow reserve (FFR) in the severe and mild lesions. However, the results of studies evaluating FFR after PCI showed a wide range of FFR values after satisfactory results of stenting according to angiography data. This additionally confirms the thesis that only one angiography is limited in determining the ischemic boundaries after PCI, and the level of FFR values after PCI is directly related to the results in the long-term period. Percutaneous coronary interventions under the control of FFR allows the operator to improve the results of endovascular treatment of coronary lesions in patients with coronary heart disease. The use of FFR in a catheter laboratory contributes to an increase in the clinical and economic efficiency of procedures, which is achieved due to the fact that the determination of FFR before PCI can significantly reduce the number of stents implanted during PCI, as well as to avoid unnecessary PCI stages in the treatment of patients with lesions of the LMCA. In addition, FFR allows to timely optimize the results of suboptimal PCI, as well as to reduce the frequency of main adverse cardiovascular events in the long-term period.

The aim of the study was to assess the treatment results in patients with anterior STEMI using primary PCI in different patient age groups, including those at late hospitalization, taking into account the initial mortality risk (MR). The study included 804 patients with anterior STEMI, aged 28 to 91 years, who were admitted to N. V. Sklifosovsky Research Institute for Emergency Medicine in the period from 2008 to 2017: 583 of them had the primary PCI performed either within the first 12 hours from the disease onset (311 patients) or at late hospitalization: after 12–72 hours (272 patients); and 221 patients treated without PCI. The distribution of patients by age: under 65 years old, 65–75 years old, and over 75 years old was 340, 139, and 104 in the PCI group, and 126, 47, and 48 in the group without PCI, respectively. In 26 death cases after PCI and in 39 of died without interventions, the state of the coronary bed, the affected area, and the immediate cause of death were determined. We have found that in the absence of reperfusion therapy (RT) in STEMI, the initially high baseline MR assessed by TIMI Risk Score corresponds to high mortality. It affects people of predominantly elderly and, especially, senile age, who more often have a proximal lesion of the main coronary arteries, which causes an extensive area of infarction with the development of fatal complications. The use of primary PCIs, including those at late hospitalization, prevents the progression of acute heart failure, the formation of LV aneurysms, and reduces the deaths rate. In different periods of time, the mortality rate with the use of primary PCI, including the delayed ones, fluctuates; it can rise with a significantly increasing number of the hospitalized at senile age. An increase in mortality is associated with complications, including those arising during procedures in severe multivessel coronary artery disease, which is more common in this patient population. Achieving angiographic success even in the absence of ECG signs of reperfusion can significantly reduce mortality in all age groups. High MR is an optimal indication for using delayed procedures. An urgent use of primary PCIs, including those at late hospitalization, allows the optimization of the STEMI treatment, and the achievement of the maximum reduction in mortality.

The use of regorafenib in the treatment of patients with metastatic colorectal cancer divides Russian and foreign oncologists into two camps. Many specialists postpone its appointment until a situation where all other options for systemic therapy have been exhausted, and the physical condition is close to unsatisfactory, and the metastatic process reaches its maximum volume. The position of oncologists adhering to such positions is based on a small number of objective answers and low survival rates without signs of progression of the process, with evidence of a more effective re-prescription of chemotherapy and targeted drugs already used in the treatment of this patient. On the other hand, an analysis of the world literature on regorafenib and options for the third line of therapy for metastatic colorectal cancer shows the ambiguity of the above approach and the potential of the drug in terms of improving the patient’s prospects by overcoming the resistance of the tumor mass to already used drugs and the ability to provide the patient with the so-called chemotherapeutic holiday.

Purpose of the study: to assess the state of lipid peroxidation processes in patients with kidney cancer in relation to the clinical factors of the prognosis of the disease and against the background of surgical intervention.

Material and methods. For the study, we used blood plasma samples from 300 patients with kidney cancer T1–4N 0–1M0–1, obtained before surgery and 8–9 days after surgery. Oxidative stress was assessed by the intensity of free radical processes by the method of induced biochemiluminescence on the BKhL-07 biochemiluminometer apparatus (Medozons Co., Russia), the activity of lipid peroxidation processes was assessed by the accumulation of initial products in the blood plasma – diene conjugates (DC), triene conjugates (TC) and fial Schiff bases (OSh) according to I. A. Volchegorsky et al. method. (1989). Statistical processing of the results was carried out using Statistica 12 and Microsoft Offie Excel 2010 programs.

Results. In patients with kidney cancer, there was a decrease in the level of DC, an increase in OSh and the ratio of Osh / (DC + TC) compared with the control (p ≤ 0.05), against the background of depletion of the resources of the antioxidant defense system. The content of DC did not differ from the norm with the size of the primary tumor of the kidney pT1–pT2 and decreased (p ≤ 0.05) in the case of the presence of the tumor pT3–pT4. At the same time, there was an increase in the OSh content (p ≤ 0.05). In patients with thrombi in the inferior vena cava system, a decrease in the level of DC was observed (p ≤ 0.05), the OSh level did not differ from that of healthy individuals. In the postoperative period, there was an increase in the content of DC (p ≤ 0.05) and a decrease in the Osh / (DC + TC) coeffiient (p ≤ 0.05) compared with the initial level.

Conclusion. Kidney cancer is accompanied by the activation of free radical oxidation processes against the background of depletion of the resources of the antioxidant defense system. Changes in the pro-antioxidant homeostasis are interrelated with the size of the primary tumor and the presence of a tumor thrombus. In the postoperative period, the activity of free radical oxidation processes in the patient’s body decreases.
Modern strategy for treatment of metastatic colorectal cancer as key to increasing life expectancy of patients with metastatic colorectal cancer without mutations in RAS genes
Authors: Artamonova E. V.
Published: August 2021

The review is devoted to the place of cetuximab in the treatment of metastatic colorectal cancer (mCRC) without mutations in the RAS (RAS wt) and BRAF (BRAF wt) genes, depending on the goals of therapy, as well as to the analysis of the inflence of various factors, including the localization of the primary tumor, on the effectiveness of treatment. Randomized clinical trials and meta-analyses conducted on their basis allow us to conclude that cetuximab in combination with an infusion doublet or triplet provides the maximum frequency of deep and early objective responses, regardless of the location of the primary tumor. The drug is superior in this parameter to both a single chemotherapy (CT) and a combination of CT with bevacizumab which is important in terms of achieving resectability in patients with potentially resectable metastases. For patients with left-sided localization of the primary tumor and RAS wt, cetuximab, prescribed in the 1st line, provides a reliable and clinically signifiant increase in life expectancy. Postponing the start of its use until 2–4 cycles of CT (until the result of a molecular genetic study is obtained) does not negatively affect the effectiveness of the 1st line of therapy for mCRC RAS wt, and with left-sided localization of the primary tumor, CT with delayed cetuximab exceeds the usage of CT with bevacizumab from the fist cycle for ORR, OS and PFS. The optimal duration of induction chemo-targeted therapy is 3–4 months (6–8 courses), after which it is advisable to switch to maintenance treatment with one cetuximab. The new mode of administration of cetuximab once every 2 weeks at a dosage of 500 mg/m 2 IV provides maximum convenience of its use.

Over the past 70 years, tourism has always been at the forefront of business transnationalization, as it has consistently used all the advantages of the transnational production and distribution system, thereby creating additional competitive advantages on a truly global scale. The purpose of this study is to analyze the evolution of the international travel market, as well as to identify a number of historical stages of its development, which the market has passed on the way to establishing strong international relations and interaction. In this article, transnationalization is defined as a modern form of organizing tourism and hotel business. It was proposed directly by entrepreneurs as one of the possible solutions to classic market problems (including limited demand and factors of production). These market problems intensified in the second half of the last century, and all of them directly influenced the development of tourism. The study analyzed the driving forces of transnationalization of the tourism and hospitality sectors, taking into account the economic effect of the synergy of transnationalization. Expansion of tourist activities of the sectoral transnational corporations along with their gradual transformation into influential subject of the world economy. All of the considered in the article synergy effects from tourist business transnationalization have nearly simultaneous impact on the process of tourist services’ production.

Tourism is an important element of the social and economic development of Russia. The northern territories play an important role in the development of the Russian economy in general and the tourism industry in particular. Nordic tourism involves careful respect for environmental and social sustainability, the promotion of traditional local knowledge and value systems, and the preservation of local cultural heritage and cultural landscapes. The article analyses the promotion of the tourism potential of Yakutia. The northern territories of Russia are rich in natural resources and economic potential but do not have an effective tourist infrastructure due to the harsh climate and vast territories of permafrost. The study presents the results of the analysis of the main tourist routes of the Sakha Republic. The main factors for the development of tourism were determined by a set of landscape characteristics (unique nature of the Lena River, biological diversity of flora and fauna), ethnocultural and historical context, as well as infrastructure considerations (proximity to the capital, inexpensive transport, and engineering systems). The study demonstrated that scientific tourism in Central Yakutia is quite real and has great prospects due to the unique landscapes. It can also give impetus to new scientific discoveries. Defining and describing cultural landscapes, collecting field materials and mapping cultural and landscape zoning can simplify the work for the creators of tourist routes in the future.
