Authors: dos Santos Karine Dias Gomes , Silva Kellen Lagares Ferreira , Seibert Carla Simone
Published: July 2023

O presente estudo utilizou a netnografia para realizar um estudo acerca das baunilhas brasileiras. O trabalho se desenvolveu com a participação de uma das autoras em um grupo de WhatsApp chamado Escola da Baunilha por um período de 6 meses. A coleta de dados foi por meio da exportação de conversa, com um backup completo do registro escrito desse grupo. Em seguida, as mensagens foram analisadas utilizando o software ATLAS ti versão 23. 1 para realização da análise de conteúdo proposta por Bardin. Para um estudo complementar foi enviado também um formulário eletrônico via Google Forms que continha perguntas abrangentes e mais específicas para sondar o conhecimento dos participantes sobre o assunto. Foram determinadas quatro categorias para análise: aquisição das baunilhas; cura das favas, reguladores de crescimento e tutor. Em geral os participantes do grupo têm dificuldade em adquirir as favas de baunilha, devido ao valor elevado e produção insuficiente. Os participantes que cultivam as baunilhas fazem a cura de forma artesanal e as utilizam para consumo próprio. Alguns respondentes utilizam reguladores de crescimento para melhorar os resultados no cultivo e utilizam como tutores espécies vegetais principalmente da família Fabaceae. Os participantes do grupo são majoritariamente de São Paulo e Distrito Federal. Os respondentes participam do grupo para compartilhar informações e experiências com outros apreciadores/estudiosos das baunilhas e na opinião deles falta mais divulgação e informação acerca das espécies que ocorrem no país, para que o Brasil tenha potencial de produção de baunilha.

Published: July 2023

O presente artigo tem como objetivo apresentar um relato de experiência dos doutorandos do Programa de Pós-Graduação em Educação e Novas Tecnologias do Centro Universitário Internacional UNINTER sobre a vivência durante a realização da disciplina Seminário de formação e desenvolvimento docente desenvolvido de maneira remota. O tema é considerado bastante relevante e essencial para entendermos o processo de construção e desenvolvimento do tema da formação no desenvolvimento profissional dos docentes na educação básica e superior, entendo a pesquisa sobre os diversos aspectos que envolvem a práxis profissional dos professores algo de suma importância pois pode gerar impactos significativos no fazer pedagógico dos profissionais da educação a partir de reflexão crítica acerca das várias realidades que envolvem o processo educativo no tocante ao ensino e aprendizagem no contexto escolar. Além do entendimento sobre os cenários em que ocorreram as aulas em espaços acadêmicos como o da Pós-graduação Stricto Sensu, durante a pandemia da covid 19.  Os relatos se baseiam nos teóricos tais como; Vygotsky (2003), Freire (2018), Romanowski (2007), Nóvoa (2002) entre outros. A metodologia utilizada durante as interações foi o seminário mediados pela tecnologia através de plataformas digitais em que os momentos ocorreram de forma síncrona. Os resultados demonstraram que embora o ensino a distância tenha alcançado um grande crescimento em vários contextos educacionais, em relação ao ensino mediado pela tecnologia digital a pandemia Covid-19 trouxe algumas mudanças que até então se acreditava que levaria alguns anos para se efetivar na prática. Para que as aulas remotas no Programa de Doutorado pudessem acontecer é fundamental que o professor conceba o conhecimento sob a ótica levantada por Vygotsky, ou seja, que todo e qualquer desenvolvimento cognitivo só será efetivo se for baseado em uma interação muito forte entre sujeito e o objeto. Isto é, o ambiente uma interação muito grande do sujeito com o objeto de estudo, integrando esse objeto à realidade do sujeito, dentro de suas condições, de forma a estimulá-lo e desafiá-lo. Durante as aulas as discussões possibilitaram o confronto com os desafios e significados, vinculados ao contexto que os discentes vivenciam em suas práticas profissionais e na vida real.

Published: July 2023

Purpose: This study aimed to compare the motor competence, executive functioning, and academic performance of students with adequate weight, overweight, and obesity.

Design/Methodology/Approach:  A total of 1631 children aged between 06 and 08 (±7.58) years old, of both genders (903 girls and 728 boys), students of the public school system in the state of Rio de Janeiro, participated in this study. To achieve the objective, participants were introduced to protocols that assessed body mass index, Motor Competence, Executive Functioning, Reading Comprehension, and Academic Performance.

Findings: When analyzing the results of the protocols related to motor development, cognitive development, and academic performance, the results show a superiority of children with weights within the expected range in relation to obese children.

Conclusion: The findings indicate a potential correlation between body mass index (BMI) and the proficiency of children in motor skills, executive functions, and academic performance. Specifically, the results demonstrate that children who are obese exhibit lower scores in all assessed variables compared to children with a BMI within the normal range.

Research Limitations and Implications: This study did not assess the participants level of physical activity or their eating habits.

Practical Implications: The research results contribute to the formulation of public policies on obesity as a public health problem, since its impacts go far beyond physical health problems.

Contribution to the Literature: This research can add to the literature on the impacts of obesity on the cognitive and motor development of children, showing the importance of developing new studies with regard to prevention.

Classification, diagnosis and treatment of Eustachian tube dysfunction literature review
Authors: Makuszewska Maria
Published: July 2023

 Introduction: The Eustachian tube (ET) is the anatomical structure that connects the middle ear with the nasopharynx. It is part of a system that, in addition to the already mentioned elements, also includes the soft palate. The functions of ET are pressure equalization, clearance of secretions and protection of the middle ear from sounds and reflux of secretions from the nasopharynx. Dysfunctions of ET are multifactorial, and the diagnostics is difficult due to lack of defined standards for assessing its function prior and post treatment.

 Aim: The aim of the study is the review of the publications concerning actual definitions and classification of ET dysfunctions, efforts of adopting unified criteria and methods of assessing its functions and ways of treatment.

  Material and methods: In the year 2015 classification was adopted which distinguish three subtypes of ET dysfunction: (1) dilatory ET dysfunction, (2) baro-challenge-induced, (3) patulous ET. Dilatory ET dysfunctions were further divided as follows: functional obstruction (most common), dynamic dysfunction and anatomical obstruction. The Eustachian Tube Dysfunction Questionnaire (ETDQ-7) enables the systematization of symptoms. Clinical assessment of the patient with ET dysfunction should include otoscopy or otomicroscopy, tympanometry, Rinnes and Webers tuning fork tests or pure tone audiometry, nasopharyngoscopy with visualization of ET orifice and opening. Other tests of assessment of ET functions like tubomanometry, sonotubomanometry and pressure chamber tests are useful research tools. Endoscopic evaluation of ET orifice should encompass the assessment of mucosa of the torus tubarius and ET as well as dynamic process of ET opening. In surgical treatment of functional obstructions of ET, the most common method is balloon dilatation tuboplasty. Several studies showed that this is safe and in high percentage of cases successful method of treatment, however the indications for this type of surgery are not yet universally accepted.

In 2019 in International Journal of Pediatric Otorhinolaryngology was published article on the introduction of Vestibular Infant Screening at the University Hospital of Ghent. The purpose of this critical review is to justify why cVEMP as a single test is neither reliable nor suitable for the diagnosis of vestibular defects, especially in infants. Another aspect is the costs incurred for such screening tests as VIS-Flanders significantly exceed the resulting social profit.
Dynamics of Indian fresh mango export
Authors: BALYAN KAVITA , KUMAR SHIV , CHAHAL V P , KUMAR SANDEEP
Published: July 2023

Increasing integration of global markets after WTO has brought several changes in fresh mango export. The sustainability of exporters' income depends on acceptance of consignments by the importing countries who have established legally vetted system of safe import of food commodities. To adjust to these changes, the Indian system of export controls faltered to meet the standards of overseas markets. Adherence to safe export norms is sine qua non to have credible sustainable export. Visualizing the need to discern and quantify the direction of fresh mango export, time series data spanning from 1990-2012 was analysed. From the analysis, it can be concluded that domestic supply of mango is mainly driven by expansion of area rather than productivity. High standards of SPS measures of importing countries raised cost of compliance of safe export norms for which Indian exporters faced problems to adjust to these standards. These challenges need to overcome through generation of research based scientific knowledge for structuring food safety norms and policy alignment according to the changing global regulations. Policy options for streamlining diversified export are to encourage food testing laboratories to get accreditation from international agencies setting up world class food testing and inception infrastructure particularly in clusters with significant presence of exporters to encourage importing countries to set up office for certification of export consignments, and to strengthen prerequisite physical resources for safe export of fresh mango.

The objective of the study was to standardize the protocol for effective and mass multiplication of four wine and juice making grape (Vitis vinifera L.) genotypes, viz. Pusa Navrang, Hybrid 76-1 (Hur Ã— Cardinal), Pearl of Csaba and Julesky Muscat. Culture initiation was undertaken on Murashige and Skoog (MS) medium supplemented with 2.0, 4.0 mg/l benzyl amino purine (BAP) and Kinetin individually and in combination with 0.2 mg/l naphthyl acetic acid (NAA). Explant subcultured on MS medium supplemented with 2.0, 4.0 mg/l indole-3-butyric acid (IBA) singly and in combination with 200 mg/l activated charcoal (AC). The rooted plants (30-day-old) were hardened using rooting medium consisting of coco peat + vermiculite + perlite (2:1:1). Among the different growth regulators tried for highest culture establishment (73.85%), minimum day to axillary bud sprout (9.31) and rooting (16.46%), maximum root length (6.28) with 2.0 mg/l BAP + 0.2 mg/l NAA treatment. Highest culture establishment recorded in the genotype Pusa Navrang (45.34%) followed by in Julesky Muscat (44%). Multiplication rate per 5 subcultures was recorded the maximum in Pusa Navrang (5.6) followed by Pearl of Csaba (5.1), and Hybrid 76-1 (4.9). In the present investigation, the application of MS medium containing growth regulators BAP (2 mg/l) + NAA (0.2 mg/l) and IBA (2 mg/l) + AC (200 mg/l) found best for culture initiation and rapid multiplication, respectively. For hardening using glass jar with polypropylene (PP) cap was a better strategy.
Effect of pre-harvest application of salicylic acid on the postharvest fruit quality of the Amrapali mango (Mangifera indica)
Authors: REDDY S VIJAY RAKESH , SHARMA R R
Published: July 2023

The shelf-life of mango (Mangifera indica L.) fruits is only 5 to 6 days under ambient conditions, which can be increased efficiently, if the rates of biological activities and/or changes are reduced by pre and/or post-harvest treatments. Hence, three different concentrations (75, 150 and 200 ppm) of salicylic acid (SA) were applied as pre-harvest treatments to Amrapali mango fruits, one week prior to their commercial harvest. Later the fruits were harvested and stored at ambient conditions (30±5 °C and 50±5 % RH). Among various concentrations of SA, the SA (200 ppm) was found to be most effective in delaying the ripening cum senescence processes through suppression of ethylene production rate (0.20 µl C2H4/kg/h) and helped in maintaining the post-harvest quality through better retention of soluble solid concentrates (SSC) (27.72 °B), titratable acidity (0.53 %), ascorbic acid (32.52 mg/100g) and total antioxidant content (11.85 µmol Trolox/g Fresh Weight ) etc. The SA treatment was also found to effectively influence the pectin methylesterase activity (0.167 µmol acid/min) as well as the lipid peroxidation (2.26 nmol/g Fresh weight) during storage in order to extend the fruit shelf-life by 3 days compared to the control fruits.

Published: July 2023

Bell pepper (Capsicum annuum L.) fruits of cultivar Indra were harvested at bright green colour stage and packed in different packaging films, viz. heat shrinkable film (15µ), cling film (15µ) and low density polyethylene film (LDPE 25µ). After packaging, the fruits were stored under two different conditions, i.e. super-market conditions (18-20°C; 90-95% RH) and ordinary market conditions (28-30°C; 60-65% RH). The shrink and cling film significantly checked the loss in weight, firmness and decay incidence and maintained various qualities attributes like ascorbic acid, chlorophyll content and overall sensory quality of the fruits during shelf-life better than unwrapped control fruits. The in-pack bell pepper in shrink and cling film created a suitable headspace environment with desired level of O2 and CO2 concentrations, which resulted in a better retention of freshness of the vegetable for its marketability. On the other hand, LDPE film accumulated very high level of CO2, which led to formation of fermenting odour and decay of fruits. The data revealed that shrink and cling film proved quite effective in prolonging the shelf-life of bell pepper fruits for 10 and 7 days under super market conditions and ordinary market conditions, respectively, as against 5 and 2 days only in case of unpacked control fruits.

This study was conducted to induce novelty in marigold cultivar Pusa Narangi Gainda through gamma irradiation via in vivo and in vitro approaches. The seedlings grown under in vivo and the proliferated cultures under in vitro, were exposed to different doses of 60Co gamma rays (5, 10, 15, 20, 25, 30, 35, 40 Gy). 20 Gy and 15 Gy dose was identified as LD50 value for in vivo and in vitro conditions (53.24 % and 52.55 % plant survival), respectively. There were morphological variations in between irradiated and non irradiated plants. Treatment with 20 Gy induced early flower bud (49, 18 days) compared to control (55.56 days) under in vivo study. Under in vitro condition, the flower color changed to yellow (yellow 10 YR) compared to the control (orange 5 YR) at 15 Gy. In M1 generation, two mutants in flower form (m1 and m3), one in colour (m4) and another one in flower earliness (m2) were isolated under in vivo mutation, whereas, five mutants in flower colour (nm1, nm2, nm5, nm6 and nm7) and two in flower form (nm3 and nm4) were isolated in irradiated plants which were quite distinct compared to non-irradiated. Variability caused by induced mutations need not to be essentially different from variability caused by spontaneous mutation during evolution, therefore, it is necessary to carry on the M2 generation. The mutants which were selected from the M1 generation were selfed to raise the M2 generation. The study revealed six putative mutants (pm1, pm2, pm3, pm4, pm5 and pm6), which could successfully maintain their distinct traits. Among them, pm3 produced early flowering in 47.89 days and pm4 gave light orange coloured flower (orange 10 YR).

Published: July 2023

A solar powered evaporative cooled storage structure (ECSS) was designed and developed for storage of fresh fruits and vegetables to increase their shelf-life. The structure consists of a solar powered exhaust fan and cooling pump for providing water to the pads. Cooling pads of different materials such as wood shaving, khas and celdec were used. The system works on the principle of a simple desert cooler. The pads are wetted with the help of circulating water through a solar powered pump and an exhaust fan sucks the cool air through the pads of the structure. The areas for the cooling system considered were 2.25 m2, 4.5 m2, 6.75 m2 and 9 m2 respectively. The results showed that under the no-load condition, the average air cooling efficiency was highest for CELdek at 78.67%, compared to 73.82% for wood wool and 70.75% for khas pad material and the maximum difference in relative humidity (RH) and dry bulb temperature between ambient and inside the cooler was 59% and 14.6°C when these materials were used in all four sides in the ECSS. This environment helped in keeping the vegetables fresh for significantly more time. This is very useful in rural areas where there is shortage of electricity or its supply is erratic for storage of fresh fruits and vegetables.

Published: July 2023

Carrot (Daucus carota L.) is a globally important vegetable crop providing a source of important nutritional compounds through carotenoid content whilst adding flavour and texture to many diets. Temperature influences growth, yield and quality of carrots in many different ways. The influence of varying temperatures on yield and quality parameters of carrots has been a topic for research during the last three decades. An attempt was done to analyze inbreds for quantitative and qualitative traits for the selection of inbreds for high temperature stress. The inbreds showed variation in plant weight, foliage weight, root weight, root length and root girth with average of 233.71g, 74.16g, 164.13g, 21.62 cm, whereas root girth ranged from 4.77-3.70 cm respectively. Anthocyanin content estimated to be highest in dark purple black inbred line IPC-126 (333.81 mg/100g) while the total carotenoid contentwas highest in root tissue of IPC-124 (14.46 mg/100g). The lycopene content ranged from 0.50 mg/100g (IPC-126) to 11.85 mg/100g (IPC-124). TSS ranged from 6.7 to 10.48 °Brix. Some inbreds performed well under extreme high temperature without affecting any quality attributes. Such inbreds could be selected for further breeding program. The results of our study will help in development of high quality superior hybrids using the promising inbreds in tropical carrot.

Are Classical Assessments Offering Adequate Insight into Post-Pandemic Teaching Methods?
Authors: McLean Kyle
Published: July 2023

Educators must continuously assess and adjust to maximize the amount of information students retain. One way to evaluate teaching effectiveness is thru pre- and post-semester assessments. Factors such as individual willingness to participate can affect the validity of these assessments. Our hypothesis was that students will more actively participate in a group activity compared with written pre- and post-semester assessments. In this study, we evaluated 3 different types of pre- and post-assessments to assess knowledge retention and participation. Participation decreased as the semester progressed resulting in only 31 of 57 students who completed all 6 of the assessments. There was an interaction (P < 0.001) between the type (individual, team, or activity) and time of assessment.  The percentage of correct answers increased (P < 0.001) between pre-semester (average 32.92 ± 1.58) and post-semester assessments (average 47.54 ± 1.58). There was a correlation (P = 0.04) between the final course grade and the post-semester individual written assessment. In conclusion, participation throughout the semester is a major issue in assessing teaching quality and knowledge retention and the utilization of group activities does not appear to impact that participation. However, the best assessment for knowledge learned remains the classical written individual assessment.

Shallow S-wave Velocity Profile Estimation using Surface Velocity and Microtremor HVSR with a Linear Velocity Increase Approach
Authors: Pramatadie Andi Muhamad , Yamanaka Hiroaki , Afnimar Afnimar
Published: July 2023

We propose a simple method for 1D S-wave velocity (Vs) profile estimation using a measured surface S-wave velocity (V1) and peak frequency of the observed microtremor horizontal-to-vertical spectral ratio (HVSR). In this method, the S-wave velocity profile is presented as linear velocity increase with depth in sediments over a bedrock layer that has a given constant S-wave velocity. Thus, the profile can be parameterized with the measured surface S-wave velocity and the velocity gradient. The gradient can be estimated based on the agreement of the peak frequencies of the observed microtremor HVSR and the theoretical ellipticity of the fundamental mode of the Rayleigh wave. We examined the applicability of the proposed method using numerical tests as well as application to actual data at five sites in the Bandung Basin, Indonesia, where observed Rayleigh wave phase velocities from microtremor array surveys were available. The applicability was confirmed in numerical tests using sample models of soil profiles in the basin. Actual application indicated the appropriateness of the estimated S-wave velocity profiles due to the similarity of their theoretical Rayleigh wave phase velocities with the observed Rayleigh wave phase velocities. Since the proposed method needs prior confirmation of the linear increase of the S-wave velocity, it is suitable for use in spatial interpolation of shallow S-wave velocity profiles with simple data acquisition.

Pengujian ini bertujuan untuk menguji kelayakan tegangan tembus pada isolasi Oli Enduro Matic-S 10W-30, Oli Federal Matic 30 10W-30, dan Oli Unioil Power Max Matic 10W-30 diharapkan ke 3 oli tersebut bisa mengganti isolasi minyak trafo apabila nantinya dalam keadaan mendesak tidak mendapatkan minyak trafo jadi salah satu dari ke 3 oli tersebut bisa dipergunakan sebagai pengganti minyak trafo. Peneltiain ini adalah metode eksperimen kami dalam menguji kelayakan Oli 10W-30 sebagai pengganti minyak trafo. Dari hasil pengujian di dapatkan bahwa dari ke 3 oli yang di uji hanya satu oli yang memenuhi standar minyak transformator itu pun hanya dalam kondisi suhu 300C yaitu Oli Enduro Matic-S 10W-30 dengan nilai 36.44 kV. Sedangkan di saat suhu 400C dan 500C tegangan tembus yang di hasilkan menurun drastis sehingga tidak sesuai lagi dengan standar minyak transformator. oleh karena itu dari ke 3 oli yang telah di uji tidak ada yang cocok digunakan sebagai isolator minyak trafo. Karena dari hasil yang didapatkan dari ke 3 oli tidak stabil atau berada di bawah standar minyak transformator, seperti yang kita ketahu bahwa trafo akan berkerja dengan temperature yang berbeda beda karena pengaruh naik turunnya beban transformator

Published: July 2023

Bürokrasi gerçekte siyasal ilişkiye bağlı bir fenomendir. Fakat Weberyen anlayışın baskın otoritesi altında bu ilişkinin dışında, bağımsız bir görünüm edinmiştir. Bu bir sapmadır. Bu çalışmada, bu sapmayı gidermek üzere, bürokrasiyi kavramsal ve kuramsal açıdan yerli yerine oturtmayı deniyoruz. Bunun için, bürokrasiyi bir siyasal ilişki olarak olgusal açıdan çözümlemekteyiz. Fakat özellikle siyasalın modern formunda, bürokrasinin siyasal ilişkiye içkin kurumsal bir bütün oluşturduğu da görmezden gelinemez. Tam bir çözümleme bunu da kapsamalıdır. Yine bürokrasinin kapitalist ve sosyalist perspektiflerden okumalarına yer vermek bu çözümlemeye ek bir katkı sunacaktır. Sonuç olarak ise, yönetimin özyönetim ve siyasal yönetim olarak ayırt edilmesi bürokrasi sorunsalının gerçek doğasını ortaya koyacak ve bu sorunsalı aşmanın yolunu gösterecektir.

Antibiotic-associated diarrhea (AAD) is a commoncomplication of antibiotic therapy, with Clostridiumdifficile infection (CDI) being a major cause of severeAAD. CDI is associated with high morbidity, mortality,and healthcare costs. The administration of probiotics isa promising strategy for the prevention of AAD and CDI,as they can create a favorable gut environment andalter the composition of the intestinal flora. Thissystematic review evaluated the use of probiotics inpreventing CDI in hospitalized adult patients. Thereview of 12 randomized controlled trials involving3,586 patients found that probiotics reduced theincidence of CDI in hospitalized adult patients by up to70%. Specifically, the probiotic strains Lactobacillusrhamnosus GG and Saccharomyces boulardii werefound to be effective in preventing CDI. However,further research is needed to establish optimal dosingregimens and to identify the most effective probioticstrains for CDI prevention. Nonetheless, the use ofprobiotics appears to be a promising strategy forreducing the incidence of CDI in hospitalized adultpatients receiving antibiotics.

Published: July 2023

The goal of this study is to adapt the Teachers’ Ratings of Child Secure Base Behaviour and Emotion Regulation Scale into Turkish culture. The research group of the study included 295 children aged from 48 to 72 months. A total of 59 teachers participated in the adaptation study for the children. Data obtained were firstly used for confirmatory factor analysis in the scale validity test. According to the CFA results, a 28-item and two-factor structure of the scale was accepted with no need for any amendments. Strong significance was found between the reference scales and the scales on which the criterion-related validity test focused. The Cronbach’s alpha value of the scale was found to be .970 in the reliability test. A strong correlation was found between the two applications in the test re-test stage. The study findings reveal that the scale is a valid and reliable assessment tool for Turkish culture.

The use of plants for heavy metal-polluted soil rehabilitation is an emerging ecologically sound and safe technique. An in vitro laboratory experiment was conducted for 15 days in Petri dishes containing 3 layers of Whatman filter papers wetted by 50 ml of heavy metals Cd, Cu, Ni, Pb and Zn, separately at 0, 10, 20, 40, 80 to 160 µM to determine their impacts on germination rate, root and shoot growth of surface sterilized alfalfa seeds. An in vivo experiment was also conducted in a greenhouse setting, and the alfalfa seeds were grown for 8 weeks in plastic pots containing 2 kg of heavy metal (Cd, Cu, Ni, Pb and Zn) contaminated clay loam brown forest soil at different concentration levels (0, 10, 20, 40, 80 to 160 mg/kg). The results of in vitro demonstrated that the rates of seed germination, root and shoot growth were affected by Cd, Cu, Ni and Pb metals at higher concentrations of 80 and 160 µM. The inhibitory decreasing order of metal toxicity on seed germination was Cd > Cu > Ni > Pb > Zn. However, seed germination increased at all Zn dosages. Meanwhile, the lower concentrations of investigated metals (10 and 20 µM) stimulated the root and shoots length and at 10 and 20 mg/kg concentration levels increase plant biomass. It was found that alfalfa was able to grow efficiently at all Zn concentrations except at 160 mg/kg. The results showed that alfalfa was able to uptake the heavy metals at the applied concentrations ranging from 10 to 160 mg/kg by various degrees. Finally, the alfalfa plants, to some extent, demonstrated their potential in cleaning the soil environment from heavy metals.
Tájtörténeti vizsgálatok a kisgombosi fás legelőn

A Hatvantól É-ra 18 hektáron elterülő, felhagyott kisgombosi fás legelőn végeztünk tájtörténeti kutatást különböző írott és vizuális források alapján a tájhasználat-történet leírása, továbbá a területen bekövetkezett fiziognómiailag elkülöníthető változások nyomon követése, ábrázolása céljából. A felszínborítás változásait az 1932-es, az 1957-es, az 1975-ös katonai munkatérképek, az 1989-ben felújított EOV térkép és a 2005-ben készült légifelvétel feldolgozásán keresztül szemléltetjük.A vizsgálati terület első írásos említése a 17. századból származik. A kéziratos térképek, a katonai felmérések és a katonai munkatérképek feldolgozása során kiderült, hogy a kisgombosi fás legelő egykori zárt erdő felnyílása révén jött létre. Birtoklástörténete bonyolult és szerteágazó. Fás legelő habitusának pontos kialakulását csak becsülni lehet. Az I. Katonai Felmérés már igen ritka magastörzsű tölgyfaerdőt említ a helyén, ugyanakkor az 1930-as évekből származó fényképanyag bizonyítja, hogy akkor még használatban lévő fás legelő volt. Fokozatosan hagyták fel, amit a katonai munkatérképek alapján készített felszínborítás-változásokat bemutató ábrák is jól tükröznek, továbbá pontos következtetések vonhatóak le a fás vegetáción végzett évgyűrűvizsgálatok eredményeiből.

A gyepesített árvízvédelmi földgátak nemcsak a talajvédelemben, hanem a kérődzők téli szálas takarmány ellátásában is fontos szerepet játszottak. Azonban a legeltetést a Vízügyi irányelvekben lefektetett töltéskezelési szabályzat megtiltotta, árvízvédelmi szempontokra hivatkozva. Ezt vitatva munkánkban tiszai árvízvédelmi töltésen folytattunk juhlegeltetést, vizsgálva ennek negatív és pozitív hatásait a földgát szerkezetére és gyepborításának botanikai összetételére. Összehasonlítottuk a földgátak mentett- és vízoldalán az állateltartó képességet. Eredményként megállapítottuk, hogy ha a legeltetés szakszerűen történik sem a földgát szerkezetén, sem a gyep összetételében nem okoz visszafordíthatatlan károsodást.
Szomszédsági mérőszámok a tájmetriában – az indexek módszertani vizsgálata
Authors: Szabó Szilárd
Published: July 2023

A tájökológiai vizsgálatok egyik fontos kérdése a táji fragmentáció fokának a meghatározása, melyben a tájmetriának kulcsszerepe van. A szomszédsági mérőszámok segítenek számszerűen kifejezni egy táj felszabdaltságát, amiből közvetve a fajok élőhelyfoltok közötti áramlásának feltételeire is következtethetünk. A tanulmány célja a szomszédsági tájmetriai indexek vizsgálata abból a szempontból, hogy milyen hatást gyakorol kiszámított értékükre a felszínborítási kategóriák számának és a térbeli felbontásnak a változása. A vizsgálatok alapját elméleti foltmintázatok adták 1 km-es eredeti pixelfelbontással, 2–3–4 kategória alkalmazásával. A raszteres felbontás hatását 100–250–500–1000 m-es pixelméret alapján végeztem el. A célom az volt, hogy egy egyszerűen nyomon követhető módszerrel bemutassam a szomszédsági kapcsolatokat feltáró metrikák értékeinek az alakulását a táj foltjainak mintázatától függően, továbbá bemutassam, hogy milyen hibákat követhetünk el akkor, amikor nem megfelelő felbontással végezzük el a tájmintázat elemzését. Eredményeim szerint mind a felszínfedettségi (területhasználati, biotóp stb.) kategóriák száma, mind a térbeli felbontás jelentősen befolyásolhatja a tájszintű szomszédsági metrikák értékeit. Változó számú felszínfedettségi kategória alkalmazása esetén más eredményt kapunk a foltok összetettségére (aggregációjára), szóródására és keveredésére. Az optimális felbontástól való jelentősebb eltérés pedig akkora hibát eredményezhet, ami megkérdőjelezi a kapott eredmény használhatóságát az ökológiai hálózatok tervezésében. Ez a tény arra hívja fel a figyelmet, hogy a vizsgált szomszédsági indexek alapján végzett tájökológiai kutatások esetében érdemes több felbontással is kísérletet tenni, figyelembe véve e mérőszámok lehetséges szélső értékeit.
Természetvédelmi terület hidrogeográfiai változásvizsgálata térinformatikai alapokon, rövid és hosszú időtartamok összehasonlításával
Authors: Kovács Ferenc
Published: July 2023

A vizes élőhelyek visszaszorulása a közelmúltban történt földrajzi folyamatok, antropogén eredetű tájváltozások meghatározó része. A klímaváltozás, mint a rendkívül változékony területet komoly károk- kal fenyegető komplex földrajzi folyamat statisztikai és térbeli meghatározása meglehetősen nehéz feladat. Változási folyamatokat kell felismernünk és térben ábrázolnunk a változékonyság ismeretében. A szükséges monitoring jellegű értékelésben a 19. századtól rendelkezésre álló térképek mellett a távérzékelési alapadatok és módszerek könnyítették meg a környezeti állapot megőrzése szempontjából kulcsfontosságú tényezőnek, a víztartalomnak a vizsgálatát. A tér- és időbeli elemzésre koncentráló vizsgálat adatbázisát a térképek mellett a közepes méretarányú és szabadon elérhető LANDSAT TM és ETM+ műholdképek alkották a lehető legnagyobb időfelbontásban. Az egy hosszabb 130 évre vonatkozó, illetve egy rövidebb 4 éves időtartamot átölelő vizsgálatunk a szigorúan védett Felső-Kiskunsági tavak mintaterületen a földrajzi szempontból évtizedek óta aktuális, veszélyes szárazodás térképezése céljából készült. A térképi és távérzékelési adatok összehasonlításánál több olyan elem is előfordul, melyeket nehéz egyértelműen besorolni egy hosszú folyamatba. A kérdéses területek előfordulása miatt a degradációs folyamat megítélésénél egy optimista és egy pesszimista szemléletet adtunk meg. Az optimista esetben a kérdéses foltoknál mindig a kedvezőbb, vagyis a vizesebb meghatározással számoltunk (természetesen a pesszimista szemlélet ennek az ellentéte). Optimista eredményeink szerint csak 5,6% szenvedte el az ár- és belvízrendezés, a csapadékcsökkenés hatásait, míg a pesszimista esetben ez akár 33,5% is lehet. A természetvédelmi tervezés, döntéshozás számára a folyamatosan gyűjthető adatokkal folytatódhat a monitoring, különös tekintettel a már általunk is alkalmazott nagyobb felbontású új szenzorokra (RapidEye).
The past in the present – remnant open field patterns in England
Authors: Hooke Della
Published: July 2023

The agricultural landscape forms an important part of Britain’s cultural heritage. Relict field systems cast light upon landscape evolution, often showing the special connections between landscape and people over time. Medieval open field systems represent a method of farming that endured for many hundreds of years, produced through, and dependent upon, community involvement. Most of these landscapes were lost in the period of enclosure in the 18th and 19th centuries as individually held farms replaced such systems; later, the large estates themselves were also frequently broken up. The few survivals of open fields in England are discussed here and the cultural changes associated with landscape change, culminating today in conservation measures to protect such features. Thus the rural landscape reveals the depth of its evolutionary history, contributing towards the rich diversity of England’s regional landscapes and the maintenance of a sound ecological balance, thereby contributing towards the preservation of cultural identity and heritage.
