Published: March 2024

A study was conducted to establish the dynamics of ecological parameters of soil by phytoindicationmethod on the basis of complete geobotanical descriptions in oak plantations of wet forest conditions of Polissia. The research analyzed the dynamics of: soil moisture (Hd; soil moisture regime (fH); soil acidity amplitudes (Rc); amplitudes of the amount of calcium carbonates (Ca) and magnesium (Mg); the amount of mineral nitrogen (Nt); soil aeration (Ae). It is established that after continuous fellings the indicators of soil parameters change both in the direction of increase and in the direction of decrease. The main reason for this is probably the removal of the edification layer - the stand, which is characterizedby a significant absorption capacity. During the process of stands’ growth, with age, there is a clear tendency to return the level of soil indicators to the original values ​​that are characteristic of mature subclimax oak plantations.Thisprocessinoak plantations begins after the closure of the crowns and the formation of their own canopy.Most soil indicators in points were characterized by a narrow range of values. In general, the obtained data on phytoindication of ecological parameters of habitats indicate the presence of a clear trend in wet soil conditions of Polissia after continuous fellings in the process of restoring the biodiversity of oak plantations.

Oak (Quercus robur L.) is one of the most common and valuable tree species in the Western Forest-Steppe of Ukraine. Much of the oak forests of the Western Forest-Steppe are concentrated in the forest district of Volyn Upland, which, despite belonging to the Western Ukrainian Forest-Steppe Forest District, is characterized by special geomorphological and climatic conditions, which contributed to the formation of valuable usually mixed oak stands,and also linden, maple, ash. The peculiarities of oak stands distribution in the northern part of the Western Forest-Steppe of Ukraine are analysed in the work. The analysis of forest typological structure of stands with the participation of oak (Quercus robur L.) in the forestry district of Volyn Upland is carried out. The structure of areas and reserves of oak stands in the context of edatopes and forest types has been studied. The average stock per unit area of oak stands of the Volyn Upland is calculated and a comparative characteristic of its ratio with the reserves of oak stands of the Volyn Upland in different types of forest vegetation conditions is made. Based on this analysis, conclusions are made on the productivity and use of edaphic conditions by oak forests in the Volyn Upland. The largest share of oak stands in the Volyn Upland is concentrated in hail conditions – 70,9%. Soil types of forest vegetation conditions make up 23,1% of the area of oak stands. According to the degree of soil moisture, Quercus robur L., in the Volyn Upland, prefers fresh conditions, where 70,6% of oak forests in the region are concentrated. In general, oak (Quercus robur L.) in the study region is involved in the formation of 13 forest types, of which 7 act as a typical species.

Published: March 2024

A new design of circular saw with hard alloy plates has been developed, its gear crown is made in two sizes of straight pointed teeth FZ1 / FZ2, alternating through one: one (slit) has a thickness equal to the thickness of the saw body and the height of the other (scraper) is less than 1.5 mm and has a thickness equal to the width of the saw. The influence of the structural parameters of the saw with combined teeth FZ1 / FZ2 on the accuracy of longitudinal sawing of wood is explained by the special design of the saw, which is divided into two stages: initially, cut tooth FZ1 cuts the middle part of the chips, forming a groove at the bottom of the saw, which holds the saw; next is FZ2 blade, which forms the left and right part of the saw at the same time, extending the formed groove to a given width of the saw. The design of the circular saw with straight sharpened cut and clean teeth FZ1 / FZ2 and a protrusion of cut teeth FZ1 1.5 mm above the cutting circle ensures straight cut and sufficiently high tool resistance in the saw with a minimum thickness of a saw blade equal o1.6 mm. The use of FZ1 / FZ2 saw reduces the width of the saw by 1.7 times compared to the classic saw with FZ teeth and, thus, reduces the energy consumption of the process and, by simplifying the design, makes the saw preparation for work less complex. Proceeding from the results of the experimental research, it is established that the saw blade with FZ1 / FZ2 combination gear wheel, under the conditions of a rational sawing mode, ensures a precision of machining within ± 0.5 mm and allows to reduce wood and electricity losses.

Features of laser welding of wood-cutting band saws
Authors: Rebeznyuk I.T. , Lazarchuk K.
Published: March 2024

Abstract. Laser welding is the most effective method of joining the ends of band saws according to the high level of existing jointing requirements; using this method allows you to form anesthetic, even and smooth sound weld without deformation. Laser welding has a number of advantages but at the same time the main disadvantage of laser welding is the high cost of equipment and the need for highly qualified maintenance. The paper considers the main features of the method for joining a number of band saws into an endless band saw by laser welding. The specific feature of  laser welding is that it produces  the highest degree of energy density on a tiny spot.  The essence of the laser welding process sis that inartificially generated laser beam is used as a source of thermal energy to per form the work. High cooling rates of the weld (up to 3,000° C/s) and high speeds of welding (up to 120 m/h) of low-carbon steels affect the ir  primary and secondary structure. The same factors provide a disordered fine-grained structure, which contributes to an increased resistance of the weld to the appearance of hot cracks. The laser welding of metals operates in three modes, the advantages and disadvantages of these modes being analyzed. Annealing after welding, accompanied by heating to a temperature of 450–470° C and holding for 30 s (recommended by Rentgen – the CR400 steel manufacturer) causes a gradual equalization of the hardness distribution. In the CR400 steel, containing chromium and tungsten at the lower allowable limit (3,5% and 5,3%, respectively), complete recovery of hard ness after annealing is not observed. Fluctuation sin hardness reach 30–35%, which negatively affects the strength of the saw. To eliminate this shortcoming, it is necessary to equalize the hardness, which can be provided by a special thermal strengthening. It is proposed to develop modes of laser thermal strengthening of the weld after the welding process, which will significantly increase the strength of the tool.
Dependence of band saw noise on the welding method
Authors: Rebeznyuk I.T. , Lazarchuk K.Ya.
Published: March 2024

The band saw used on a woodcutting band saw machine must be securely connected to the endless band, and the connection method must provide both the required strength and the lowest noise level during operation. The research methodology covers the stage of detecting, using a professional noise level meter,  the sections of the cutting mechanism with the highest level of noise and the stage of measuring the noise level on a band saw machine at an idle mode with tension supports, for saws: 1 – connected by arc welding, and the joint weld is located at an angle of 90° to the rear edge; 2 – connected by laser welding, and the seam is located at an angle of 90° to the rear edge; 3 – connected by laser welding, and the seam is located at an angle of 60° to the rear edge. The experiments were carried out on a modern horizontal band saw machine MEBOR HTZ 1200 with a wide band. The machine is designed for lengthwise cutting of logs in order to obtain high quality lumber. Measurements of the noise level during the operation of band saws showed that noise is generated in certain sections of the cutting mechanism – the section of the saw run  on the pulley, the section  of contact of the saw with the first guide and the section of the saw exit from the second guide. It has been established that during the operation of horizontal bandsaw machines, in which saws are used and whose ends are connected by traditional arc welding and the weld is located at an angle of 90° to the rear edge of the saw, the noise level exceeds the sanitary norms by a maximum of 35 dB. It is found that welding of band saws by modern laser method, when the seam is located at an angle of 60° to the rear edge of the saw, allows obtaining  a noise level 10–15 dB less than with laser welding of the saw when the seam is at an angle of 90° to the indicated edge.  An analysis of the noise spectra showed that the linear spectrum of sound pressure has a uniform distribution of the sound energy radiation intensity in a wide frequency range of 125–8000 Hz. It was found that, starting from the third octave (125 Hz), for a laser-welded saw with the seam located at an angle of 60° to the rear edge of the saw, the noise level exceeds the sanitary norms (80 dB) by 19 dB. The experimental studies have shown a significant reduction in noise when using band saws welded by a laser method and with the seam located at an angle of 60° to the rear edge of the saw. It was found that in some frequency bands the noise level exceeds sanitary norms and in this regard the design of a band saw machine with a new damping device is proposed, which, according to data from the technical literature, will provides further noise reduction; and in order to clarify the amount of noise reduction, it is necessary to conduct further experimental studies.

Regime de queima das caçadas com uso do fogo realizadas pelos Xavante no cerrado
Authors: Martins Melo Mônica , Hiroo Saito Carlos
Published: March 2024

A literatura tem subestimado a questão das queimadas aplicadas aos ecossistemas silvestres com propósitos culturais. Apesar disso, há indicações de que o fogo foi largamente utilizado como ferramenta de manejo pelos povos indígenas em diversos tipos de ecossistemas. No Brasil, os indígenas utilizaram e ainda hoje usam o fogo como ferramenta de manejo. Objetivo deste artigo é investigar e caracterizar os aspectos que integram o regime de queima adotado nas caçadas com fogo realizadas pelos Xavante, e oferecer subsídios para o manejo sustentável do fogo no Cerrado. Na primeira etapa de campo, foram realizadas entrevistas estruturadas que tiveram como base um roteiro contendo questões que têm sido formuladas pelas pesquisas atuais em ecologia do fogo. Na segunda etapa, considerando os resultados da primeira fase e o entendimento das concepções ambientais dos pesquisados, foram realizadas entrevistas parcialmente estruturadas. As caçadas com fogo são realizadas no período da seca, entre os meses de junho e setembro. A periodicidade de queima e a mudança de localização vão depender do tipo de fitofisionomia. Os Xavante realizam uma queima prévia, que ocorre depois do período de chuva, como uma das formas de controle, assim como fazem o planejamento das áreas a serem queimadas. A definição do período de repouso das áreas após a queima depende de avaliação dos anciões. A atividade de caçada com uso do fogo apresenta resultados semelhantes ao padrão tradicional de queima indígena relatado pela literatura.Â
Revisão sobre os efeitos do fogo em eriocaulaceae como subsídio para a sua conservação
Authors: De Oliveira Neves Ana Carolina , Cadaval Bedê Lúcio , Parentoni Martins Rogério
Published: March 2024

Eriocaulaceae é uma das famílias mais numerosas e ricas em endemismos do Cerrado. A beleza das suas inflorescências faz com que espécies conhecidas como sempre-vivas (plantas de diversas famílias que tem suas inflorescências pouco alteradas após serem colhidas e desidratadas), sejam cobiçadas pelo mercado nacional e internacional de plantas ornamentais secas. O declínio das populações de várias eriocauláceas tem sido atribuído a um aparente aumento da freqüência de queimadas realizadas no Cerrado para renovar pastagens, preparar o solo para a agricultura e devido ao manejo extrativista. Neste trabalho, revisamos a literatura científica que trata da ação do fogo em sete espécies de Eriocaulaceae que ocorrem no Cerrado. O fogo promoveu o aumento do número de indivíduos reprodutivos nas três espécies estudadas quanto a esse aspecto (Actinocephalus polyanthus, Comanthera elegantula e Syngonanthus nitens), de inflorescências por indivíduo em duas entre quatro espécies (Comanthera elegantula e Leiothrix crassifolia) e de sementes por capítulo na única espécie estudada nesse aspecto (S. nitens). O fogo estimulou ainda o recrutamento por plântulas devido Ã  eliminação da vegetação competidora em três das quatro espécies estudadas (A. polyanthus, C. elegantula e Leiothrix arrecta, e por brotamentos em S. nitens). Em espécies policárpicas, o aumento do esforço reprodutivo pode impactar negativamente a produção de inflorescências nos anos seguintes Ã  primeira estação reprodutiva após a queima (ex. C. elegantula e S. nitens), além do crescimento e sobrevivência de indivíduos em idade reprodutiva (ex. C. elegantula</i.). Entretanto, a mortalidade e a redução do crescimento podem ser atenuados pela coleta de escapos antes que as sementes sejam produzidas, como foi observado em C. elegantula. Queimadas freqüentes podem levar populações ao declínio através da exaustão do banco de sementes, mortalidade (principalmente de plântulas) e estímulo Ã  reprodução e morte precoce em espécies monocárpicas. Por outro lado, a exclusão de queimadas por longos períodos pode levar as populações ao envelhecimento e ao declínio devido Ã  redução no recrutamento e aumento da mortalidade, causadas pelo aumento da vegetação competidora. Considerações sobre o manejo de espécies de Eriocaulaceae são feitas, considerando diferenças em suas histórias de vida.Â
Fogo e artesanato de capim-dourado no Jalapão - usos tradicionais e consequências ecológicas

Published: March 2024

O artesanato de hastes florais de capim-dourado Syngonanthus nitens, Eriocaulaceae) costuradas com as fibras de folhas-jovens de buriti (Mauritia flexuosa, Arecaceae) tornou-se símbolo da região do Jalapão e mesmo de todo o estado de Tocantins na última década. Além do extrativismo vegetal, esta importante atividade econômica envolve o uso do fogo para o estímulo da floração do capim-dourado. Este artigo sintetiza resultados de estudos etno-ecológicos desenvolvidos em cooperação com comunidades rurais e gestores ambientais do Jalapão entre 2002 e 2011. Os estudos centraram-se nos efeitos do extrativismo de hastes de capim-dourado e folhas-jovens de buriti nas populações destas espécies, bem como nos efeitos do uso do fogo para o manejo dos campos úmidos de colheita de capim-dourado. Conforme relatado por extrativistas experientes, queimadas bienais estimulam a floração, ou seja, a produção de hastes do capim-dourado. Além disto, simulações numéricas indicam que queimadas bienais são ideais para o crescimento populacional de capim-dourado em longo prazo. Intervalos de queima mais longos, apesar de não estimularem a floração, não prejudicam as populações desta espécie. As populações de capim-dourado são muito resistentes a queimas, no entanto, apresentaram flutuações anuais significativas em resposta a variações também anuais na precipitação durante o período chuvoso. Estas características são provavelmente compartilhadas por outras dezenas de espécies vegetais dos campos úmidos. A colheita de hastes de capimdourado após 20 de setembro, como determinado por legislação estadual em Tocantins, não tem efeitos negativos sobre os indivíduos tampouco sobre as populações de capim-dourado. A colheita de folhas-jovens de buriti para a obtenção das fibras utilizadas para costurar o capim-dourado não causam efeitos negativos em indivíduos e populações de buriti, na intensidade praticada no Jalapão. A legislação atual é adequada a todo o estado do Tocantins, pois previne a colheita precoce de capim-dourado, que é extremamente prejudicial Ã  conservação da espécie. Ações para prevenção da colheita precoce devem envolver educação ambiental e fiscalização. Como forma de reduzir a incidência de incêndios de grande extensão na região deve-se capacitar os moradores locais para o uso controlado do fogo. Queimadas controladas nos campos úmidos devem ser feitas com extremo cuidado para evitar incêndios em fisionomias sensíveis ao fogo, como as áreas de ocorrência de buriti.

Published: March 2024

Various approaches are used to improve crop production. Seed priming is one of the simplest and least expensive methods currently used to ensure rapid and uniform yields. Our study highlights the role of priming and imbibition in improving seed germination. The objective of this study was to investigate the effect of seed imbibition and hormopriming with 0.1 mM gibberellic acid (GA3) on germination performance and biochemical changes in fenugreek (Trigonella foenum-graecum L.) radicles. The results showed that hydropriming and imbibition with GA3 significantly improved germination performance and radicle growth. Concurrently, treatments induced stimulation of the antioxidant activities of superoxide dismutase, ascorbic peroxidase, catalase and guaiacol peroxidase, and decreased lipid peroxidation, stimulated an increase in total non-enzymatic antioxidant capacity and reduced glutathione content. Accumulation of hydrogen peroxide and cytochemical analysis of reactive oxygen species (ROS) in situ confirmed the role of imbibition in stimulating ROS. Interestingly the effects of imbibition with gibberellic acid were more effective then hormopriming, probably due to the partial degradation of GA3 during dehydration process.
Epäluotettavia, ansioituneita ja vietteleviä?
Authors: Vuorinen Piia
Published: March 2024

Sukupuoleen liitetyt aikalaiskäsitykset ja ennakkoluulot vaikuttivat pitkälle kylmään sotaan asti turvallisuus- ja tiedusteluviranomaisten tapaan palkata naisia lähinnä toimistotehtäviin. Naisvakoojia puolestaan tarkasteltiin usein vaarallisen viettelevinä toimijoina. Tässä artikkelissa käsittelen, miten tällaiset käsitykset vaikuttivat Suomen valtiollisen poliisin (Etsivä Keskuspoliisi / Valtiollinen poliisi) toiminnassa vuosien 1919–1944 välillä. Kolmen esimerkkihenkilön kautta piirtyy kuva siitä, miten naiset näkyivät ja toimivat valtiollisen poliisin valvonnan arjessa. Orvokkia (s. 1912), Selmaa (s. 1889) ja Sylviä (s. 1907) erottaa heidän sijoittumisensa vakoilun, vastavakoilun ja valtiollisen valvonnan eri puolille, mutta miestoimijat tarkastelivat heitä jossain määrin samanlaisten käsitysten läpi. Käsitykset olivat kuitenkin ristiriitaisia. Nainen saattoi ennakkoluuloista huolimatta toimia valtiollisen poliisin arvostamana tiedustelijana, mutta samanaikaisesti miesetsiviä varoitettiin naistiedustelijoihin ihastumisen vaaroista. Viranomainen salli yksittäisille sen palveluksessa olleille naisille heidän tehtäväkuvaansa laajemman roolin valtiopetoksellisen toiminnan jäljittämisessä, mutta ylläpiti muuten tiukkaa rajaa nais- ja miestyöntekijöiden välillä. Valvontaviranomaiset eivät juuri saaneet näyttöä, että vakoilusta kiinni jääneet naiset olisivat pyrkineet seksuaalisuutensa avulla hankkimaan – tai saaneet hankituksi – valtiosalaisuuksia.

Operações de crédito, desigualdade, inadimplência e crescimento da renda: uma avaliação para os estados brasileiros no período 2001-2014
Authors: Santolin Roberto , Gama Fábio
Published: March 2024

Este artigo discute as relações entre desigualdade de renda, inadimplência, disponibilidade de crédito e crescimento da renda nos estados brasileiros no período de 2001 a 2014. Mecanismos relacionados à seleção adversa, risco moral e falências bancárias podem acarretar relações endógenas entre renda e crédito. Este texto avaliou se os estados brasileiros com predominância da desigualdade de renda e acentuado crescimento da inadimplência bancária possuem restrições ao crédito ativas que podem impactar negativamente o crescimento econômico. Por meio de um modelo em painel dinâmico foi possível constatar que estados mais desiguais, e com maior taxa de inadimplência, possuem menor disponibilidade de crédito e menor crescimento da renda per capita.

A transparência pública municipal é atrelada a diversos fatores em estudos brasileiros e internacionais. Este estudo verificou a relação entre os fatores socioeconômicos e políticos e o índice da transparência medido através do Ministério Público Federal (MPF) dos 497 municípios do estado do Rio Grande do Sul (RS). A partir da aplicação de estatística bi e multivariada, identificou-se que as variáveis população, dívida, investimento e Índice Firjan de Desenvolvimento Municipal (IFDM) apresentam relações positivas com o índice de transparência municipal, enquanto que desemprego e participação eleitoral relacionam-se negativamente com o mesmo índice. Não foi verificada relação do índice de transparência com os fatores: competitividade política, gênero do prefeito, reeleição, escolaridade, gênero e renda da população. Concluiu-se que, de modo geral, os fatores que afetam a transparênciapública municipal em outros países não possuem o mesmo efeito sobre a transparência dos municípios do RS, estimulando a continuação do estudo a nível nacional.

Este estudo tem por objetivo obter evidências empíricas, com base na literatura de federalismo fiscal, sobre os determinantes da restrição orçamentária fraca por parte do governo local devido à existência de transferências de socorro feitas pelo governo central, em resposta a casualidades. A análise baseia-se na regressão de efeitos fixos para dados em painel a fim de testar a hipótese too big to fail de que quanto maior o banco, localidade em termos populacionais, maior o socorro a ser recebido. Verificou-se que a hipótese foi condizente para o caso brasileiro para os anos de 2009, 2010, 2013 e 2014, ao explicar cerca de 60% das transferências de socorro aos municípios, mostrando, portanto, que ciclos eleitorais e municípios maiores em termos do número de trabalhadores são determinantes nas tais transferências, tendo em vista que indicadores socioeconômicos e fiscais parecem ser relevantes. Assim, a literatura indica que uma maior descentralização aloca melhor os recursos no que tange às necessidades da população.

This study aims to assess the impact of the bug on clocks, caused by the end of daylight saving time, on absenteeism in the National High School Exam (Enem) of 2019. To achieve this goal, we use quasi-experimental methods of regression discontinuity design and difference-in-differences. The results found indicate that failures in digital devices contributed significantly to the reduction of absenteeism, making Enem 2019 to obtain the lowest abstention since 2001. In addition, the results indicate that the most benefited socioeconomic group were students with family monthly income up to a minimum wage, whose mother’s education are no higher than complete elementary school.

Instituído pela Lei no 3.983, de 27 de dezembro de 2005, o Programa Bolsa Trabalho (PBT) constitui-se em uma política pública que tem como público-alvo pessoas com idade entre 15 e 24 anos e residentes no município de Osasco-SP. Assim, em resposta à falta de uma avaliação do programa, que visa combater o abandono e a evasão escolar juvenis resultantes do emprego precoce, este estudo buscou investigar seu impacto sobre a educação dos jovens do município, contribuindo, dessa forma, com a literatura sobre avaliação de políticas públicas. Para isso, utilizou-se o método de controle sintético, a fim de comparar a trajetória dos dados de Osasco com os dados do “município sintético” para a taxa de matrícula de jovens no ensino médio, assumindo o ano de implementação do programa como evento/intervenção (2006). Identificou-se que o PBT produziu impactos positivos e significativos na variável de educação somente dez anos após sua implementação.

Eventos climáticos extremos e registros de desastres têm aumentado no Brasil e ainda é recente a criação de políticas públicas consolidadas para a gestão do risco de desastres. A história de ocupação e desenvolvimento econômico do país levou a retirada da cobertura vegetal original e um possível desequilíbrio nos ecossistemas e seus serviços que contribuem com soluções sustentáveis para a redução do risco de desastres (RRD), adaptação às mudanças climáticas e desenvolvimento sustentável. Os programas de pagamentos por serviços ambientais (PSA) podem servir como instrumentos de políticas ambientais de transferência de recursos financeiros para quem presta serviços ambientais. O Brasil regulamentou recentemente a Política Nacional de Pagamento por Serviços Ambientais (PNPSA) – Lei no 14.119/2021 – e este estudo objetivou verificar a inclusão dos serviços ecossistêmicos de regulação que contribuem para a RRD nesta legislação. Utilizou a análise de diagnóstico de problemas apresentada pelo Guia de Políticas Públicas (Casa Civil da Presidência da República, 2018) organizado em etapas com metodologia mista. Essa pesquisa contribui com as investigações científicas para o PSA e discute as contribuições da PNPSA na área de redução do risco de desastres que possam trazer ganhos socioambientais diante do contexto de crise ambiental global.

BACKGROUND OF THE STUDY:* Hypertension, characterized by elevated blood pressure, is a major public health concern globally. It is a leading cause of cardiovascular diseases, including stroke. Stroke, a neurological condition, is a significant cause of mortality and disability, especially in low- and middle-income countries. Hypertension is a predominant risk factor for stroke both globally and in our country. Hence, there is a critical need to enhance stroke education, particularly targeting low-income individuals at high risk, through public health campaigns and targeted health education efforts. OBJECTIVES OF THE STUDY: 1. To assess the knowledge of hypertensive patients regarding stroke risk factors and prevention. 2. To determine the association between knowledge scores and selected socio-demographic variables. HYPOTHESIS: H1: There will be a significant association between the knowledge level of hypertensive patients and their socio-demographic variables. CONCEPTUAL FRAMEWORK: This study adopts the health belief model proposed by Becker as its conceptual framework. METHODOLOGY: The research employed a descriptive survey design to assess stroke risk factors among hypertensive patients attending the medical OPD of HSK Hospital & Research Centre in Bagalkot. Non-probability convenient sampling was used to select 100 hypertensive patients for the study. Data collection utilized a structured questionnaire consisting of two sections: Section I focused on socio-demographic variables, while Section II assessed stroke risk factors. RESULTS: The study revealed that hypertensive patients exhibited varying levels of knowledge regarding stroke risk factors. On average, the overall knowledge score was 55.3%. The percentage distribution of hypertensive patients based on their knowledge level showed that 24% had poor knowledge, 50% had average knowledge, and 26% had good knowledge. CONCLUSION: The study identified a significant association between the knowledge level of hypertensive patients and certain socio-demographic characteristics, particularly the source of information. However, no significant associations were found with other variables such as age, gender, education, occupation, and health history. This underscores the importance of targeted health education interventions aimed at improving awareness of stroke risk factors among hypertensive patients.

Resilience is the ability to cope with problems and to depict a strong persona despite difficulties in life. Everyone has their strengths and weaknesses and their definition of resilience. Knowing how to deal with and stand through adversity is salient. This study established the awareness of students in the context of resilience and their inspiring initiatives toward resilience. It also measured the resilience of students using Connor Davidson’s resilience scale. One hundred senior high school students were the respondents in this study. The researchers used Google Forms to gather the data. The results revealed that the students are familiar with the idea of resilience, as they understood, defined, and gave inspiring initiatives toward it. They were also considered resilient using Conor Davidson’s resilience scale. In the item list, the highest mean in the scale was 3.64 (Having faith in God may help me occasionally), while the lowest was 2.77 (I have a sense of control over my situation). The researchers suggested programs and activities that will strengthen the resilience of students, including creating programs for resilience and obtaining a growing mentality.
Global Warming and the Future Generation
Authors: Ghosh Arup
Published: March 2024

Global Warming has become one of the burning problems of the day. Every year, the average temperature of the Earth is being increased. Such problem is called Global Warming. This problem has started long ago. In the last 50 years, the situation has become worst. There are many causes of Global Warming. Firstly, the trees are being destroyed in good number. As a result, there is no perfect balance in the ratio of CO2 and O2. Secondly, the excessive fuel consumption is another direct cause of Global Warming. Thirdly, the excessive use of CFC has made the situation alarming. The direct impact of Global Warming is that the condensed ice of the pole regions has begun to be melted. Gradually, the sea level rises. Shortly, the coastal countries of the world will be washed away. Besides, owing to Global Warming, the holes have been created in the O3 layer. As a result, the harmful rays of the sun enter the surface of the Earth. Some measures may be taken to solve the problem of Global Warming. Firstly, trees should be planted in good number. Secondly, the excessive use of CFC should be banned. Above all, public awareness should be created among the masses against the terrible consequence of the Global Warming.

Published: March 2024

 Background: Teledentistry is same as telemedicine. It has come out as a new diagnostic tool for different disciplines of dental care. As a part of teledentistry, teleperiodontics concentrates on the application of digital technology for communication and facilitate the innovative technology of telecommunications in the field of periodontics. The teleperiodontics has an infinite potential of access to the periodontitists from a distant rural area and thus enhance effective delivery of oral health care to the remote under privileged rural areas. It will make easier for early diagnosis of periodontal disease to treat it in its early stage. It allows the periodontitists and the patients to interact through video conferencing and data exchange system. But teleperiodentistry is in its infant stage and not much penetrated into the diagnosis and treatment field of periodontics. Hence, the objective of this survey study was to assess the attitude, knowledge, and application of teleperiodontistry in day to day practice among the periodontitists and other dental practitioners at different levels. Material and Method: A questionnaire comprising of 27 close ended questions to evaluate the attitude, knowledge, and practice of teleperiodentistry and teledentistry was circulated among the dental surgeons of dental colleges present in Karnataka. Result: A total of 120 responses were received. Majority of the responses were not aware about teleperiodentistry and also not agreed for diagnosing and prescribing oral hygiene practices and medicines for management of periodontal health. Conclusion: The potential of teleperiodentistry needs to be delved into by the periodontitists with an objective to deliver a better periodontal care to distant patients who are unable to visit them.
