THE ROLE OF PROFESSIONAL MODULES IN SECONDARY VOCATIONAL SCHOOLS FOR THE SELECTION OF THE FIELD OF COLLEGES

Snežana Štetić — 2023-08-18

This paper examines the connection between secondary vocational education and continuing education. The influence of professional subjects and their impact on students and the creation of attitudes about further education, as well as the implementation of various, combined training models, are studied in particular. For the purposes of this research, a total of 201 students from three secondary vocational schools in the fields of trade, catering, tourism, economics, law, and administration were surveyed using a random sampling method. The educational profiles of the tested students are economic technician, tourist technician, cook, and waiter. The research objective was to determine whether the quality of professional subjects is important when choosing further tourism studies. In addition to the fact that teaching professional subjects develops certain students’ competencies, the application of the quantitative methodology in the research showed that it also affects the choice of future educational profiles with high school students. The surveyed students have significantly opted for the choice of faculties and colleges of applied studies in natural and social sciences and humanities.

THE ESTIMATION OF FLOOD AREA BASED ON A FEW SELECTED AND WEIGHTED PARAMETERS: CASE STUDY OF THE NANGKA RIVER BASIN, BALIKPAPAN (INDONESIA)

Totok Sulistyo — 2023-08-18

In several previous studies on flood analysis and estimation, there was no clear rationale for why different researchers used a different combination of parameters in the determination of flood zones. Such research results raise the question of how to select a few dominant parameters without reducing the objectivity of the analysis. This research proposes the standardization of parameters selection by using Pareto Analysis in screening a few vital flood parameters from numerous parameters that prevail in certain areas. The selection of the right dominant parameters is the key to achieving the analysis goal and it will also simplify the analysis processes. This flood zone estimation study uses a combination of Pareto Analysis, Analytic Hierarchy Process (AHP) and Geographic Information System (GIS). The results of the study include a flood zonation map. The study area can be classified by its level of vulnerability as follow: very low vulnerability zones (0.003 km2), low vulnerability zones (5.588 km2), medium vulnerability zones (11.876 km2), high vulnerability zones (8.629 km2), and very high vulnerability zones (2.198 km2). The validation shows that the estimation of the most vulnerable zone is consistent with field validation and the flood event history of several locations in the study area. As a result, the developed model can provide an accurate flood zonation map, enabling stakeholders to take appropriate mitigation measures for different areas.

INUNDATION RISK OF SEWERAGE SYSTEM ACCORDING TO THE CONCEPTS OF HAZARD AND VULNERABILITY—CASE OF ALGIERS CITY

Sana Gaya — 2023-08-18

Algiers city frequently experiences significant flooding during rainy weather due to the overflow of its storm sewer network (SSN). Through modeling, simulation, and field studies, vulnerable points of the network have been identified. These points are classified based on a combined assessment of hazard and vulnerability. Hazard is estimated using the Analytical Hierarchical Process (AHP) method, which considers the return period, overflowing height, slope, elevation, and waterproofing. On the other hand, vulnerability is determined by population density. Risk is determined by multiplying hazard and vulnerability. Additionally, a classification based on the FMECA method's criticality index has been performed to complement the approach. The concordance between the two methods is evaluated using Lin's concordance correlation coefficient (CCC), showing strong agreement. The sensitivity analysis conducted on the models highlights their reliability and robustness, making the obtained results trustworthy and useful for network managers. This analysis aids in effective flood management by allocating resources and interventions to the most vulnerable areas of Algiers city.

CLIMATIC AND ANTHROPOGENIC IMPACTS ON FOREST FIRES IN CONDITIONS OF EXTREME FIRE DANGER ON SANDY SOILS

Milan Milenković — 2023-08-18

Forests on sandy soils are particularly vulnerable to fire. The study area in this research was Deliblatska peščara (the Deliblato Sands), one of the most endangered areas in Serbia. The linear trends, the polynomial trends and the Pearson correlation coefficient (r) were applied. Statistically significant decrease in the number of forest fires was found, while the increasing trends of the burned area and burned forest area were not significant. There was also an increase in the air temperature during the same period. In a study of the connection between forest fires and the Atlantic Multidecadal Oscillation (AMO), significant values of r were statistically observed only for the annual number of fires. The highest values were recorded for June (–0.373) and July (–0.375), and for summer r = –0.374 (statistically significant at p ≤ .01). As for the AMO in the main fire season (February–August), r = –0.331 (statistically significant at p ≤ .01). In settlements in Deliblatska peščara area, there were trends of the decreasing number of inhabitants, agricultural population, and agricultural households in the investigated period. These trends contribute to the reduction of fire risk. The r value between the dynamics of the number of fires and the population is .50 (statistically significant at p ≤ .01). The reduced agricultural activity contributes to the reduction of fire risk, while increased tourist presence is a risk factor.

MODEL OF THE LINKAGE BETWEEN LAND COVER CHANGES TO WATER DISCHARGE AND FOOD PRODUCTIVITY: THE CASE OF THE KONAWEHA WATERSHED IN INDONESIA

Jasman — 2023-08-18

Changes in watershed land cover have an impact on reducing water discharge, as well as other derivative impacts such as the productivity of food crops, horticulture, and plantations. This study tries to offer a conceptual model of the effect of changes in watershed land cover, water discharge, and food productivity through food crops, horticultural crops, and plantation crops. This study uses a quantitative approach based on time series data between 2002 and 2021. Data is analyzed using a structural model approach with SEM-SmartPLS software. As a result, changes in land cover have a significant effect on water discharge, but they have no effect on food productivity. Water discharge has a significant effect on food production, and changes in land cover greatly affect food productivity through the role of intermediary variables (mediation) of water discharge. In 2041, changes in land cover can reduce water discharge by around 47.9%. Then the water discharge is estimated to have an impact on the productivity of food crops by 62.3%, vegetable productivity by around 45.7%, and plantation crop productivity by around 72.7%.

GEOCITY—A NEW DYNAMIC-SPATIAL MODEL OF URBAN ECOSYSTEM

Yaroslav Vyklyuk — 2023-08-18

In this paper the initialization of the city is considered, which consists of several steps, including the creation of city objects with their locations, creation of residents with their attributes and own daily schedules, etc. A description of the model is provided as a tuple of attributes. The adequacy of the simulation model is checked based on the statistical data from the city of Lviv, Ukraine. Generated locations of city ecosystem objects are presented. The daily schedule of residents is simulated. A possible work schedule for each specialty is given, and separate schedules are created for working days and holidays. A unique schedule is predicted for the resident, which depends on their age and work specialty. The dynamics of visits to facilities by residents on weekdays and at weekends are analyzed. Based on the conducted experiments, the adequacy of the model and its realistic reflection of the functioning of the city's ecosystem during the day are proven. It means that by using this model, researchers can assess the impact of different behavioral scenarios on the residents within the city ecosystem more reliably. This enables a better understanding of how certain actions or changes in behavior can affect the spread and control of diseases in a specific geographic area. This model has the potential to serve as a foundation for future modeling of systems at the medium and macro scales.

READING THE SIBERIAN CITY-TEXT: SPATIAL SEMANTICS AND SEMIOTIC POLITICS OF URBAN TOPONYMIC LANDSCAPES IN YAKUTSK (RUSSIA)

Olga Lavrenova — 2023-08-18

The article studies the spatial semantics of Yakutsk’s urban text (Sakha/Yakutia, Russia) as a component of the cultural landscape. The research is based on the theoretical approaches of the Tartu-Moscow School of Semiotics, scholarly traditions of post-Soviet cultural (or the so-called “humanitarian”) geography, and modern critical studies of toponymy. The authors analyze spatial semantics and controversial elements of political and cultural symbolism of the urban text, which combines indigenous Yakut, Russian, and Soviet cultural components. With more than four hundred toponymic examples, this case study reveals the semiotic structure of Yakutsk toponymic system as a combination of urbanscape symbolization processes. For the first time, the article empirically shows, with the help of toponymy in the space of a post-Soviet city, the relationship, interaction, and positioning of the three cultures. In addition, the semantics of toponyms is typologized, which allows to quantitatively, qualitatively, and cartographically describe the process of “writing” the urban text.

REGIONAL ISSUE, INNOVATION, AND THE ECOLOGICAL FOOTPRINT

Vladislav Spitsin — 2023-08-18

This paper models the relationship between economic development and environmental progress. It investigates the relationship between investment in innovation and uncontained emissions in the selected Russian regions from 2013 to 2018. The database contains information for 72 locations and is comprised of 432 observations (panel data, 72 regions multiplied by 6 years). Random-effects regression models have been applied to analyze panel data. In a study of 72 Russian regions over the period of 2013–2018, this research demonstrates that the growing research and development (R&D) intensity of regional firms leads to a larger ecological footprint and growing emission intensity. These effects are negatively moderated by the per capita income of the region’s residents and regional enrollment in higher education. The effects are positively moderated by the export intensity of regional firms. The results suggest that economic and ecological aspects of sustainable development are at odds with each other and indicate that regional policymakers should account for the negative ecological externalities of economic development when devising policies aiming to facilitate regional growth.

FAMILY AS A SOCIAL FACTOR DETERMINING DEMOGRAPHIC TRENDS

Larisa Minasyan — 2023-08-18

Society’s demographic development holds great importance for all social processes: economy, education, science, culture, and others. Therefore, it is important to evaluate the various factors influencing the formation of demographic trends and understand their significance. This paper considers a range of sources influencing the formation of young people's attitudes toward family values, namely: the immediate environment, mass media, media content, literature, social surveys, social advertising, and propaganda, as well as bloggers as a modern element of media communications that has a fairly large influence on the young audience. The paper analyzes Russia’s policy of the demographic problem, which is associated with the currently being implemented Concept of the State Family policy in the Russian Federation until 2025 (The Concept) aimed at strengthening and protecting the family as the fundamental basis of the Russian society. The paper presents the results of mass surveys among the Rostov region youth: 1) on the key points of the Concept the sample included 450 young people aged 20–29 and 2) on the youth’s preferences for various types of mass media with a sample of 634 respondents aged between 16 and 25. It was revealed that the core foundations of the family culture are sufficiently established in the Russian Federation with the dominance of the marriage relations as free, voluntary, and equal association of men and women, which is consistent with the state policy of support and development of family values.

ASPECTS OF TOURISM SUSTAINABILITY ON ORGANIC FARMS IN SLOVENIA

Dejan Cigale — 2023-08-18

In 2020, 957 tourist farms in Slovenia were offering accommodation and/or food and beverages. Due to the legal framework (the law requires a high minimum percentage of own production), the offer of Slovenian tourist farms is strongly linked to their own agricultural production and the local rural environment. The paper addresses various aspects of sustainable rural tourism, focusing on organic tourist farms. The research’s goal was to find out whether Slovenian organic tourist farms are more sustainable than other (non-organic) tourist farms in terms of the presence of various elements (environmental friendliness, biodiversity preservation and nature conservation, equity and social justice, economic success) of sustainable tourism. These elements were selected to address all the three dimensions of sustainability—environmental, social, and economic. The research used secondary sources data on organic production and various sustainable tourism practices on tourist farms (accessible tourism, sustainable tourism labels, links with protected areas, etc.) and some other relevant characteristics of these farms (the production of native and traditional crop varieties). In addition, a survey was conducted on a random sample of 129 tourist farms. The results have shown that the assumption of greater sustainability of organic tourist farms is valid, not only in the system of agricultural production, which is the legally established basis for labeling the farm as organic, but also from some other aspects (greater representation of sustainable labels, greater presence of native/traditional varieties and breeds, more frequent links with protected areas, etc.).
