Predicting Drape of Fused Collar using Design of Experiment
Authors: Girija Renjini , Rajagopal Sudhakar
Published: June 2022

The fused collar components used in shirt manufacturing requires a specific fall and drape that depends on the type of used interlining. The interlining selection is primarily based on the subjective evaluation of fused composites. There is a need to predict the behaviour of fused shirt collars objectively. The drape of fused composites can be indicative of the shape and fall of the shirt collar. The aim of this paper was to propose a set of polynomial equations using DOE that can predict the drape behaviour of fused shirt collars before and after the washing. The Plackett-Burman design was used to screen the influential factors and the full factorial design was used to derive the polynomial equation explaining the effect of factors on the drape behaviour of fused shirting samples. The prediction was attempted with easily measurable parameters of component materials and the fusing process. The study found that the fabric weave, cover factor, raw material, interlining weight and pressure applied during the fusing process have a significant effect on the drape of fused collars. This information can be used in the 3D sampling of fused shirt components.
Female Consumers’ Clothing-related Attribute Expectations Differ According to Their Gender Identities
Authors: Doğrul Ümit , Tekeli Sena
Published: June 2022

It is necessary to determine the factors that affect consumers’ preferences in the ready-made clothing sector, where competition is intense. Gender is accepted as one of the most fundamental factors affecting purchas­ing decisions not only in the ready-made clothing industry, but also in many other sectors. However, rapidly changing environmental conditions require going beyond traditional patterns in explaining consumption be­haviors. Accordingly, the concept of gender, which is socially constructed, has also been conceptualized from a psychological point of view. In this study, the concept of gender was based on psychological foundations and it was investigated whether female consumers’ clothing-related attribute expectations differ according to their gender identities. Questionnaires created in line with the purpose of the study were applied to 393 people who were selected by convenience sampling. The data were collected through a face-to-face survey. Research hypotheses were tested with ANOVA analysis. As a result of the research, it was found that female consumers’ clothing-related attribute expectations differ according to gender identities. In the literature, no study has been found that examines the changes in the clothing-related expectations of female consumers according to their gender identity roles. In this context, it is expected that the study will make significant contributions to both the managers in the clothing sector and academics.
Assessment of Changes in Corn Husk Fibres after Acid Treatment
Authors: Bajpai Pragati , Jana Utpal , Ratnapandian Saminathan
Published: June 2022

Sustainability is desirable in any activity, including farming. Adding value to agricultural wastes such as stover (waste from corn cultivation) would provide financial benefits to farmers while reducing the environmental load of disposal. The literature identifies stover as being a raw material for bio-ethanol and a reinforcement for composites. Fibre from corn husks is generally extracted using an alkali digestion method followed optionally by enzymatic degradation. In this study, acid treatment was investigated for its feasibility to improve the desirable characteristics of alkali extracted corn husk fibres. The results revealed that increasing the acid concentration decreased fibre properties such as average fibre length, linear density and elongation at break. However, breaking tenacity achieved a maximum value, on treatment with 7.5 g/l sulfuric acid, before decreasing. These properties indicate the treatment’s adequacy for use in textile products. Acid treatment did not significantly alter thermo-gravimetric analysis values, indicating that the fibre could withstand wet processing conditions.

Published: June 2022

Integrating wind power and solar power plants into a power system has significantly grown over the past decade and is expected to grow to unprecedented levels in the coming years. In Vietnam, much large-scale wind power and solar power plants have been built and connected to the power system in recent years. To investigate and evaluate the impact of these power plants on system power operation, the 110kV power transmission network of Binh Dinh province in Vietnam is used in this paper. In the system, the Phuong Mai 3 wind power plant with a capacity of 21MW, the Fujiwara solar power plant with a peak capacity of 50MWp, and the Cat Hiep solar power plant with a peak capacity of 49.5MWp are modeled by using the PSS/E software to simulate and analyze their impacts on power system stability of the 110kV transmission network in Binh Dinh province, Vietnam. Besides, the control strategies of these power plants are also established to investigate their impacts on the network. In addition, this paper proposes three typical scenarios for the wind power and solar power plants in the system. For each scenario, the grid's operating parameters such as voltage variations and frequency variations are acquired for analyzing and evaluating their impacts on the frequency and voltage variations of the network. The simulation results show that the 110kV power transmission network remains in a stable operation mode after the fault scenarios for the wind and solar power plants. Furthermore, these simulation results provide some guidance for the actual operation

The Contribution of Circular Tourism to the Sustainable Development of Greece
Authors: Economou Agisilaos
Published: June 2022

Tourism today is an organized activity, which serves a variety of travelers’ entertainment needs, but at the same time brings financial resources to the places that receive visitors. In other words, it is an economic activity that lies in the laws of supply and demand. Therefore, the process of tourism development is largely related to what a place has to offer in terms of natural and cultural resources and services, and is a positive economic process which brings financial resources to the place that develops it.

However, in many Greek tourist destinations, due to the increased number of tourists they receive, there is an over-consumption of their resources and an imbalance in relation to the carrying capacity of the area. As a solution to the environmental and social problems created by tourism, in the present work, circular tourism is proposed for Greece. That is, the one who is based on the respect and preservation of socio-cultural and environmental resources, as well as the harmonious coexistence of tourists-visitors and employees in the tourism sector and the local community

Authors: Abdullahi Ibrahim
Published: June 2022

The President of the Federal Republic of Nigeria while acting within his constitutional powers as enshrined under section 175 of the Constitution of the Federal Republic of Nigeria 1999 (as amended) and with the approval of the Council of State, pardoned the erstwhile governors of Taraba and Plateau States; Rev. Jolly Nyame, Joshua Dariye and 157 others with respect to the various offences for which they were convicted and serving various terms of imprisonment. There exists genre of mixed reactions arising from the grant of the pardon largely based on the morality involved. This paper using the doctrinal research methodology appraised the presidential pardon granted by delimiting the confluence between morality and legality and observed that it is very vivid from section 175(1), (2) & (3) of the Constitution of the Federal Republic of Nigeria, 1999 (as amended), there is no criterion fixed before the discretion is exercised by the President in consultation with the Council of State. The paper concludes that it will serve no good to an accused/defendant to spend a life incarcerated when he can still be useful to himself and the society and recommended that the wide discretionary powers of the President as well as those of the governors need to be checked by constitutional amendments by providing and or listing the factors/criteria that the President in consultation with the Council of State, would have to take into consideration before the exercise of the said pardon.

Berührung auf Todeshöhe: Maurice Blanchots Uneingestehbare Gemeinschaft (Bataille, Nancy, Duras)
Authors: Bengert Martina
Published: June 2022

Focusing on Maurice Blanchot’s La Communauté inavouable (1983), this text investigates possibilities of thinking and performing communities that interact with and constitute one another “à hauteur de mort” (Bataille).Following the twofold structure of Blanchot’s text, the first part of the essay in its first part unfolds the notion of communitas in order to show how Maurice Blanchot, Georges Bataille, and Jean-Luc Nancy formulated a new concept of community by distinguishing it from liberal, socialist, Christian or fascist forms of community that all had become extremely problematic by the beginning of the Second World War at the latest. By doing so they themselves performed an ‘unavowable community.’The second part of the essay engages with Marguerite Duras’ La Maladie de la mort, a novella that is the main subject of the second part of La Communauté inavouable. Here, the performative power of language is delineated by means of the idea of a ‘community of lovers’ that manifests itself, in contrast to romantic forms of togetherness and unity, precisely in the breakdown of communicatio and communitas.
If you prick us: Shylock and the Politics of Touch
Authors: Döring Tobias
Published: June 2022

Shylock is the most celebrated and contested figure of a stage Jew, who makes his memorable appearance in Shakespeare’s problematic comedy The Merchant of Venice (c. 1596). His best-known speech “If you prick us do we not bleed? If you tickle us do we not laugh?” – often cited out of context as a plea for tolerance – engages with the politics of touch as a way to constitute and at the same time question an emphatic practice of communion. My contribution looks at this speech once again, and at the figure that delivers it, in a double perspective: offering a dramatic exploration of touch management as well as a metatheatrical exploration of the conditions and effects of playacting. Thus, Shakespeare may have staged Shylock’s body politics so as to test the possibilities and power of his own medium, the theatre, to touch.

(M: Sn, Si, and Al) were reviewed systematically from several aspects, such as conductivity, stability, and crystal structure. The advantages and disadvantages of each electrolyte were briefly considered and compared. The method of the preparation was presented with experimental and theoretical studies. The analysis that has been carried out showed that the solid electrolyte Li10GeP2S12 is superior to others with an ionic conductivity of 12 × 10−2 S cm−1. This conductivity is comparable to that of conventional liquid electrolytes. However, the availability and high price of Ge are the problems encountered. Furthermore, because sulfide-based solid electrolytes have low chemical stability in ambient humidity, their handling is restricted to inert gas environments. When solid sulfide electrolytes are hydrolyzed, structural changes occur and H2S gas is produced. The review’s objective includes presenting a complete knowledge of sulfide-solid electrolyte synthesis method, characteristics, such as conductivity, structure, and stability, as well as generating more efficient and targeted research in enhancing the performance of the chemical substance.
Private Labels Strategy, Retail Profitability and Bargaining Power in the Fluid Milk Market
Authors: Chen Xuan , Liu Yizao
Published: June 2022

This paper studies the competition between private labels and the role of private labels in determining the bargaining outcomes between retailers and manufacturers as well as retailer profitability in the fluid milk market. We differentiate private labels from different retailers and develop a structural model of demand and a Nash-in-Nash vertical bargaining model of supply. Using 2004–2011 Nielsen Homescan data at monthly-county level, we estimated the average bargaining power of retailers and how various factors influence their bargaining power with a random-coefficient discrete choice model of demand. With the full bargaining model specification, this paper then conducts simulations to isolate the role of private label in bargaining and retailer profitability, comparing the effectiveness of alternative private label strategies. Results indicate private label milk from different retailers are close competitors and retailers have more bargaining power than manufacturers. Further, factors such as the manufacturer size, private label share, and their private label position can significantly affect retailers’ bargaining power. Moreover, the counterfactual analysis shows that lowering private label prices and other private label strategies such as private label program expansion and retailer advertising could not only increase their profitability but also allow retailers to benefit from the bargaining with manufacturers.
Wavelength division multiplexed radio-over-fiber (WDM-RoF) system for next-generation networks with dispersion compensating fiber
Authors: Goel Pooja , Kaushik Rahul
Published: June 2022

Radio-over-fiber (RoF) is a technology in which radio frequency (RF) signals are distributed from central station to remote antenna units using fiber. Wavelength division multiplexing (WDM) is a technique in which different data streams are allowed to be sent parallely over a single fiber at different frequencies for increasing bandwidth. Hence, RoF combined with WDM technology is a prominent solution for many applications. In this article, we have designed an 8-channel 40 Gbps WDM-RoF system for future generation networks. The performance of the system has been evaluated using a simulator and then compared with a 4-channel existing system. A dispersion compensating fiber with a dispersion value at −85 ps/nm/km is used for combating nonlinearity. The simulated 8-channel WDM-RoF system has been analyzed by varying bit rate, input power, number of loops (transmission span), and channel spacing using performance parameters such as Q-factor and BER. It has been observed that the performance of the network improved as the channel spacing increased from 50 to 200 GHz. Moreover, the system performance is reliable up to 200 km.
The Neolithic Sequence of the Middle Dunajec River Basin (Polish Western Carpathians) and Its Peculiarities
Authors: Valde-Nowak Paweł
Published: June 2022

For some time, there has been more information about the Neolithic settlement on the left bank of the middle Dunajec in the Wiśnicz Foothills. In addition to the intense traces of Linear Pottery Culture, there are clear traces of the continuation of the settlement here at the fifth millennium BC and the beginning of the fourth, which represent groups of the Lengyel-Polgar cycle. These discoveries confirm the high qualities of this part of the Polish Carpathians for early agricultural colonization. Also, the selection for the settlement of the highest landscape zone and hilltops is very characteristic and tells a lot about the specificity of this mountain group for prehistoric settlement, also in the context of the old approaches to the existence of trans-Carpathian passages in the Neolithic.
Is It Just the Location? Visibility Analyses of the West Pomeranian Megaliths of the Funnel Beaker Culture
Authors: Matuszewska Agnieszka , Schiller Marek
Published: June 2022

The article attempts to apply visibility analyses to megalithic tombs of the Funnel Beaker Culture in the Pyrzyce Plain in north-western Poland. The analyses were carried out on 23 megalithic monuments in order to answer the questions whether the sites chosen by the builders of the Funnel Beaker Culture for the construction of their monumental megalithic tombs were optimal in terms of visibility and whether there is evidence that the megalithic cemeteries may have been constructed with the aim of establishing visual contact with each other and between settlements. Visibility analyses were carried out on a hypothetical landscape model that did not include flora such as forests, grasses or other obstacles in the terrain other than relief, in order to simulate an “open” landscape type. The estimation of parameters such as the visibility and discernibility of megalithic tombs proved that the builders of the Funnel Beaker Culture may indeed have chosen terrain-exposed sites for megaliths. However, other sites have been found that seem to be much more optimal in terms of visibility and terrain exposure than the present ones. Visibility analyses of megalithic cemeteries among themselves did not reveal significant “chains” of visual connections, even though they were located in exposed landscape areas. Investigations of the visual connections between megalithic cemeteries and known settlements of the Funnel Beaker Culture suggested possible visual contacts. The results of these analyses might suggest that a visual connection between cemeteries and settlements could be crucial for the megalithic builders, while it could be almost completely irrelevant between cemeteries.

Published: June 2022

The aim of this study is to investigate the numerical analysis of an innovative model containing, bioconvection phenomena with a gyrotactic motile microorganism of magnetohydrodynamics Williamson nanofluids flow along with heat and mass transfer past a stretched surface. The effect of thickness variation and thermal conductivity feature is employed in the model. Bioconvection in nanofluid helps in bioscience such as in blood flow, drug delivery, micro-enzyme, biosensors, nanomedicine, for content detection, etc. For simulation procedure, the mathematical partial differential equations are converted into dimensionless systems owing to dimensionless variations such as magnetic field, power index velocity, Williamson parameter, wall thickness parameter, thermal conductivity variation, Prandtl number, thermal radiation, Brownian motion, Lewis number, Peclet number, and different concentration parameter, etc. For numerical simulation, New Iterative Technique (NIM) numerical algorithm is adopted and employed for the linear regression planned for the proposed model. For comparison purposes, the homotopy technique is employed on the flow model. Close agreement is seen between both methods revealing the accuracy and consistency of NIM numerical technique. Many features of no-scale constraints are evaluated through graphical data for a key profile of the flow model. Results show that microorganism concentration is heavy due to the magnetic effect and Hall current.
Lycorine impedes 7,12-dimethylbenz(a)anthracene exposed hamster oral carcinogenesis through P13K/Akt and NF-κB inhibition
Authors: Gan Yi , He Ai’e , Zhu Lilei , Yao Yao , Lv Chunhua
Published: June 2022

Objectives

Oncogenic signaling pathways that are activated abnormally play a key activity in tumor initiation and development. This research aimed to examine the preventive efficiency of lycorine in the buccal pouch hamster tumor model based on its capacity to target phosphoinositide 3-kinase (PI3K)/Akt and nuclear factor-kappa B (NF-κB) signaling cascades.

Methods

The induction of oral tumor in male golden Syrian hamsters was done by 7,12-dimethylbenz [a] anthracene (DMBA) painting on the left buccal pouch thrice a week for 10 weeks. The chemopreventive effect of lycorine (20 mg/kg b.w.) was assessed by treating orally for 14 weeks of the experimental period. The biochemical endpoints such as lipid peroxidation (LPO), antioxidants, and phase I and II detoxification agents were analyzed.

Results

The treatment of lycorine to DMBA-induced hamsters drastically suppressed tumor incidence and tumor size and reverted the levels of the biochemical indicator. Moreover, lycorine significantly downregulated the p53, Cyclooxygenase 2 (cox-2), and P13K/Akt signaling and inhibited the phosphorylation of NF-κB and nuclear factor-kappa-B-inhibitor alpha (Iκ-Bα) in DMBA-induced hamsters.

Conclusions

The oral administration of lycorine effectively inhibited tumor cell proliferation, restored the antioxidant, LPO, and detoxification enzymes, and inhibited NF-κB signaling in oral tumorigenesis. Thus, the use of lycorine after a proper clinical trial could be effective for oral tumorigenesis treatment.

Published: June 2022

In vitro study was carried out to test the efficacy of Azadirachta indica A. Juss. (Neem), Nicotiana tabacum Linn. (Tobacco), rhizomes of Zingiber officinale Rosc. (Ginger) leaves of Carica papaya Lam. (pawpaw) and seeds of Piper nigrum Linn. (Black pepper) and a chemical fungicide (mancozeb) at three concentrations of plant extracts (30, 60 and 90 g/L) and mancozeb (4, 8 and 12 g/L). The concentrations were amended in potato dextrose agar (PDA). A. Niger was isolated from rotted tissues of yam tubers obtained from Kadarko in Keana Local Government Area of Nasarawa State, Nigeria. The research was conducted at Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. Results revealed that P. nigrum and Z.officinale were the best in fungi toxicity against A. niger at their respective concentrations throughout the period of incubation. This was followed by C. papaya, A. indica and N. tabacum respectively. Mancozeb gave 100 % inhibition at all concentrations tested throughout the period of incubation. Though all the extracts at all concentrations produced significant inhibitory effect (P ≤ 0.05) on mycelial growth of A. niger; the concentrations of 60 g/L and 90 g/L of the plant extracts and 4 g/L of mancozeb were considered more effective and are therefore, recommended for the control of A. niger. This has shown that there is high potential in these natural plant products for the control of yam disease if properly harnessed to replace chemical fungicide which are often harmful to the environment, toxic to man and very costly to purchase.

Published: June 2022

Natural Rubber (NR) an agricultural product is an important raw material in a broad spectrum of industries such as automobile and pharmaceutical. NR sector has its local and global dimensions. Thus the trend and pattern of natural rubber price in India: an, exploratory analysis. Annual average price of natural rubber (NR) in India during the 18 year period from 2000-01 to 2017-18 was analyzed with the objectives of delineating the trend, identifying the different phases and direction of price movement and the contributing factors. Hence, the present study explores the seasonal and cyclical trend in domestic and international prices of natural rubber in India. The month wise seasonal index in domestic and international price of natural rubber was calculated by moving average method. It was lowest in the month of January and November and highest in the month of July and June in domestic and international market respectively. Thus, the farmer could not receive the better price by postponing the sale of produce during the month of September to February to later month of the year. The analysis of cyclical indices in both domestic and international price shows that there is an uneven cycle both in domestic and international market of natural rubber. The NR price in India did not show any significant pattern of consistent movement towards a particular direction in the long run. Keywords: Price; Natural Rubber and Cyclical indices;
An Exemplary Declamation in Defense of Rhetoric (Rh. Her. 4.1–10)
Authors: Grillo Luca
Published: June 2022

In the prologue to the Rhetorica ad Herennium book 4, Cornificius boldly departs from tradition: he will create his own examples to illustrate styles and figures of rhetoric, rather than drawing from poets and orators, as Greek manuals typically did. This methodological discussion, which resembles a declamation, portrays itself as an exemplum in that it embodies the precepts exposed in books 1, 2, and 3. Moreover, this exemplary discussion partakes in a larger debate between philosophy and rhetoric and must be considered in its historical and cultural context.
Radioiodine remnant ablation in stage I adult papillary thyroid carcinoma: does it improve postoperative outcome?
Authors: Hay Ian D , Kaggal Suneetha , Thompson Geoffrey B
Published: June 2022

Objective

To determine whether radioiodine remnant ablation (RRA) reduces cause-specific mortality (CSM) or tumor recurrence rates (TRR) after potentially curative bilateral thyroidectomy (BT) in low-risk adult papillary thyroid carcinoma (APTC) patients, we compared postoperative outcomes in 1836 pTNM stage I APTC patients having BT alone with 832 having BT+RRA during two consecutive 25-year periods.

Methods

The THEN cohort (consecutively managed during 1966–1990) comprised 809 patients (36% having BT+RRA) and the NOW cohort (1991–2015) comprised 1859 patients (29% BT+RRA). Analyses of differences in occurrence rates between BT alone and BT+RRA patients were performed with SAS software.

Results

During 1966–1990, when RRA rates rose ten-fold, 20-year CSM after BT alone was 0.6% and after BT+RRA was 1.2% (P = 0.66); during 1991–2015, when RRA rates progressively fell, no PTC deaths occurred in 1859 patients. In the THEN cohort, RRA did not significantly improve TRR at local, regional, or distant sites (P > 0.1), when compared to BT alone. RRA in NOW cohort was administered to 49% of node-positive (pN1) patients and 17% of node-negative (pN0/NX) patients (P < 0.0001); TRR therefore, were examined separately for pN0/NX and pN1 patients. In 1157 pN0/NX cases, 20-year locoregional TRR were 3.1% after BT and were higher (P = 0.049) at 8.6% after BT+RRA. In four pN1 groups, stratified by metastatic nodal burden, RRA did not significantly reduce the locoregional TRR observed after BT with curative intent (P > 0.5).

Conclusions

In a 5-decade experience, RRA administered postoperatively to stage I APTC patients did not reduce either CSM or TRR and should probably not be indicated when such patients undergo potentially curative BT.

OBJECTIVES

Our aim was to compare the effect of 2 treatment models on attendance and child weight status: a less intense guided self-help (GSH) program delivered in the primary care setting versus traditional family-based behavioral treatment (FBT) delivered in an academic center.

METHODS

We conducted a randomized clinical trial among 164 children between 5 and 13 years old with a BMI ≥85th percentile and their parents. The intervention group (GSH) received 14 individual sessions over 6 months, with 5.3 hours of treatment. The control group (FBT) received 20 group-based sessions over 6 months, with 20 hours of treatment. Main outcomes included proportion of sessions families attended and change in child BMI z-score (BMIz), percentage from the 95th BMI percentile, difference from the 95th BMI percentile at the end of treatment, and 6-month follow-up.

RESULTS

Mean age of children was 9.6 years, BMI z-score 2.1, 49% female, and >90% Latino. The odds of attending GSH compared to FBT was 2.2 (P < 0.01). Those assigned to GSH had a 67% reduced risk of attrition (hazard ratio = 0.33, 95% confidence interval 0.22–0.50, P < .001). Intent-to-treat analysis showed no between-group differences in change in BMIz and percentage from the 95th BMI percentile over time. Combined, there was a significant reduction in BMIz from baseline to posttreatment (β = −0.07 (0.01), P < .01, d: 0.60) and a slight increase from posttreatment to follow-up (β = 0.007 (0.13), P = .56).

CONCLUSIONS

This study provides support for a novel, less intense GSH model of obesity treatment, which can be implemented in the primary care setting. Future studies should examine effective approaches to dissemination and implementation of GSH in different settings to increase access to treatment.

The aim: to describe the dynamic changes in mental capacity during education in secondary school in the implementation of traditional and meritocratic educational program.

Materials and methods. The study involved 56 secondary schoolchildren in the dynamics of learning, which were divided into 2 groups depending on the education system. The level of mental capacity was assessed using proofreading tests of V. Ya. Anfimov. Statistical data processing was performed using one-way analysis of variance and t-test in the software package IBM SPSS Statistics 20.

Results. During the period of basic education, the level of influence of the type of educational program, type of subject and day of the week on the accuracy of the test performance increased, the amount of work increased by 16.2-16.7 % (p<0.01) and its accuracy decreased (p<0,05). Higher initial and post-load intensity of mental capacity was revealed in schoolchildren with meritocratic education (353.23±8.52 and 341.41±8.65 respectively), and with a traditional system - higher and stable accuracy (5.68-5.86 errors) and productivity of mental work (35.29-35.72 conventional units; p<0.01). The weekly efficiency curve was the opposite in terms of accuracy for 6th and 9th grade schoolchildren, and the identical in terms of volume. In meritocratic education, a higher level of intensity was registered in the mathematics lesson, and in the traditional educational program − accuracy against the background of negative dynamics of quantitative and complex indicators.

Conclusions. Gender and age features of intensity, accuracy and productivity of mental work during basic education and the level of influence of factors of the educational process on them are established. The increase in the level of educational load was accompanied by an increase in the intensity and accuracy of mental work due to the adaptation of schoolchildren to the peculiarities of learning in secondary school and the stabilization of physiological processes. Comparison of weekly curves of mental capacity during training allowed to identify certain age trends in the formation of mental fatigue

The article contains the results of scientific research on the features of the formation of environmental competence of education seekers in the context of preventing environmental pollution during the war in Ukraine. The growing role of environmental competence of people is emphasized. Attention is paid to the protection of the environment in the context of armed conflicts and hostilities. The state of formation of ecological competence of students in the context of hostilities has been analyzed. A sufficient theoretical level of ecological competence formation has been testified along with a low degree of ability to apply knowledge of the safe behavior paradigm and implementation of health-preserving competence in difficult environmental circumstances. Theoretical and practical studies of Ukrainian scientists, starting with the armed conflict on the territory of Ukraine of 2014 have been considered. The length and specific focus on clearly defined environmental issues have been determined. The need to develop the ability of students to use the acquired knowledge in practice, particularly during the development of environmental programs or action plans for the restoration of areas, affected by hostilities, has been updated. The features of the formation of ecological competence of education seekers in the context of preventing environmental pollution during the war in Ukraine have been determined and analyzed. The world experience of conducting the educational process in war conditions has been analyzed. Suggestions are given on the need to minimize the time for preparation for training and reduce available resources in difficult times of war. The advice of psychologists on the peculiarities of the organization and implementation of educational and cognitive activities during the war has been given. The need to develop the ability to use the acquired knowledge in practice, particularly during the development of environmental programs or action plans for the restoration of areas, affected by hostilities, has been updated

The possibility of forming natural concepts in older preschool children is proved. Analyzed and selected in accordance with the purpose of the study, the definition of the term "concept" indicates that natural concepts are part of ecological competence of the child. Unlike representations, which reflect the object in a set of many different features, both significant and insignificant, the concepts carry a general, social experience, denote the essence of the object and distinguish it from all other objects. An important task of the teacher is to stimulate students' desire to acquire knowledge independently, to transform children in active participants in the educational process, to understand the essential features and connections of phenomena and objects of nature, which means to form concepts about them.

In the process of forming a natural concept, it is impossible to do without thinking operations, which include comparison, analysis, synthesis, abstraction and generalization. At about 5 years of age, there are significant changes in the child's thinking, but purposeful pedagogical influence will significantly increase the effectiveness of this.

In the course of the research methods, forms and techniques for the formation of natural concepts in students were selected. Verification of data formation initially took place at the ascertaining stage of the experiment and after the forming stage. Compared to the initial study, after organized work, the number of children with a high level of formation of natural concepts increased by 10 %, also the number of children with a medium level of formation increased by 7 %, and the number of low level decreased by 18 %. Thus, specially organized forms of work, selected methods and techniques help to form natural concepts in older preschool children
