Dietary fiber was used for reduce feed cost in local animal production. However, other advantages effects were interesting to study. Therefore, the objective of this research was to investigated effect of fiber source diet on performance, carcass quality, oxidative stress and intestinal morphology in Thai native chicken. A total of 300 one-day-old (mixed sex) crossbred native chicks (Pradu Hang dum) were randomly assigned to 5 treatments in completely randomized design (CRD). Each treatment had 10 replicates with the crossbred native chickens 6 bird/replicates (1 to 12 weeks of age) were given different levels of banana stem and Napier grass. Treatment diets received as follows a basal diet; 100%, no supplement or control group (CON), basal diet; 95%, 90% supplemented with the banana stem at 50 g/kg, 100 g/kg (BS 5%, BS 10%) of diet, respectively, and basal diet; 95%, 90% supplemented with the Napier grass at 50 g/kg, 100 g/kg (NG 5%, NG 10%) of diet, respectively. The results of the study showed that the use of fiber source: banana stem at 50 g/kg and Napier grass 100 g/kg of the diet improved growth performance. The result showed benefits to increase body weight, improve feed conversion ratio (FCR) and feed cost per gain (FCG), improve to gut health by increase villus height (VH), Villus width (VW) in duodenal and jejunal small intestine morphology, reduced malondialdehyde (MDA) levels in serum (p < 0.001). In addition, significantly higher thigh meat percentage (p < 0.05) without effecting visceral weight and overall carcass percentage.

The present study aimed to evaluate live yeast dietary supply instead of rbST application in lactating dairy cows. Thirty-five Holstein cows (37.1 ± 7.8 kg/d of milk yield and 524 ± 27 kg of body weight; mean ± SD) were used in a completely random trial to evaluate: 1) rbST: animals treated with 500 mg of rbST every 14 d; and 2) Yeast: animals fed diets containing 40 g/d of live yeast. The trial lasted for five subsequent 14-d periods. Treatments showed no effects on cows’ feed intake. Yeast reduced large and small particles selection indexes compared, feed residue and starch in feces compared to rbST. Cows treated with rbST had increased glucose, triglycerides, and AST, and decreased cholesterol and urea serum concentration. In addition, yeast reduced somatic cells count and increased milk yield and cows’ production efficiency. Although treatments showed no effects on milk chemical composition, yeast increased saturated to unsaturated fatty acids ratio. Yeast increased saturated and short-chain fatty acids, whereas reduced unsaturated and cis-9 trans-11 C18:2 FA content in milk fat. Thus, yeast could be used instead of rbST to improve milk yield and the productive efficiency of cows in a short-term evaluation

The objective of this research was to determine factors influencing to fat-to-protein ratio (FPR) in the first-lactation of dairy cows raised in tropical climate. The dataset included fat percentage, protein percentage, and FPR values from 160,506 records representing 23,201 first-lactation cows that calved between 1993 and 2017. These cows originated from 508 farms in all regions of Thailand. The data were analyzed using the general linear model procedure in the R program. The models included herd-year-season of records, and breed group as fixed effects, and age at calving and days in milk as covariates. The result showed that the average fat percentage, protein percentage, and FPR were 3.560±0.960, 3.130±0.390 and 1.150±0.330, respectively. Effects of herd-year-season of records, breed group, age at calving, and days in milk were highly significant for all traits (P<0.05). Cows containing less than 87.50% Holstein Friesian (HF) blood gave fat percentage, protein percentage and FPR higher than 93.75%HF and 87.50-93.74%HF. The FPR was highest in the winter and lowest in the summer. In conclusion, present results indicated that fat percentage, protein percentage and FPR are clearly influenced by both genetic and non-genetic factors. Therefore, development of different breed, feeding systems, according to season and herd is needed to produce quality of fat and protein percentage.

Here we examined the feed and nutrient intake of captive small Indian civets (Viverricula indica) housed at the Chiang Mai Zoo (CMZ) and Demonstrated Farming Under Royal Project (DYF) in Ban Dong Yen in Thailand. The feed type and intake was recorded for 4 males and 5 females at both CMZ and DYF. Feed samples were collected for chemical analysis and nutrient intake was calculated in terms of dry matter (DM) to compare CMZ and DYF. There were 11 and 5 feed types at CMZ and DYF, respectively. DM intake of small Indian civets at CMZ was significantly lower than at DYF (32.84 ± 0.852 % vs 38.90 ± 0.184 %; P<0.05). Crude protein, ether extract (crude fat), ash, Ca and P intake of civets at CMZ was significantly lower than the intake at DYF (P<0.05). Meanwhile, crude fiber and NFE (nitrogen free extract) intake of civets at CMZ was significantly higher than at DYF (P<0.05). The amount of wax released by civets at CMZ was significantly higher than those at DYF (2.14 ± 0.43 vs 1.49 ± 0.01 g/head/month) (P<0.05). Results of this study provide guidelines and references for feeds and feed intake for captive small Indian civets.

The study aimed to elucidate serum and testicular oxidative stress changes induced by bisphenol A (BPA) and their amelioration by Azanza garckeana (AG) pulp extract and melatonin. Adult New Zealand White rabbit bucks (n = 42), with average live weight of 1.2 ± 0.03 kg and aged 10-18 months were fed ad libitum on a commercial diet. They were randomly divided into seven groups of six (6) bucks each. Group A was administered distilled water (1.5 mL); group B, BPA (100 mg/kg); group C, AG (500 mg/kg); group D, melatonin (1.0 mg/kg); group E was pre-dosed for six weeks with BPA (100 mg/kg), then AG (500 mg/kg) for another six weeks; group F was pre-dosed for six weeks with BPA (100 mg/kg ), then melatonin (1.0 mg/kg) for another six weeks; and group G was pre-dosed for six weeks with BPA (100 mg/kg), then AG (500 mg/kg) and melatonin(1.0 mg/kg) for another six weeks. There was a significant increase (p < 0.05) in the activities of both serum and testicular superoxide dismutase and catalase, concentrations of and reduced glutathione concentration as well as a decrease in MDA concentration in treatment groups. Percentage dead sperm, spermatozoa abnormalities such as detached sperm heads, free, coiled and bent tails in the groups exposed to BPA increased significantly (p < 0.05) compared to controls. It is concluded that BPA-induced oxidative stress. The administration of AG only ameliorated this negative effects better than melatonin. However, optimum results was seen when both substances were administered synergistically.

In the present study, reproductive toxicity caused by cyclophosphamide on sperm parameters, biochemical parameters, histopathology and protective effect of wheatgrass juice was examined. There were total 6 groups of adult Wistar albino rats. Each group had 6 rats. After 24hrs of the last treatment, rats were sacrificed by cervical dislocation and sperm parameters like sperm count and motility, plasma malonaldehyde (MDA) levels, catalase (CAT) levels, superoxide dismutase (SOD) and glutathione (GSH) activities in testicular tissue, and testicular histopathological changes in the testicular tissue were examined. Administration of cyclophosphamide showed an increase in plasma MDA level and decrease in SOD, GSH and Catalase activity. These values were statistically significant. However, wheatgrass juice treatment along with cyclophosphamide markedly showed improvement in reducing Cyclophosphamide-induced oxidative stress, and normalized sperm characteristics and testicular histopathology. Thus, in conclusion, cyclophosphamide causes fertility changes which leads to male infertility, whereas wheatgrass juice has a protective effect on reversing the testicular damage and male infertility.

Published: July 2023

Adverse drug reactions (ADR) can be manifested in different forms, among these cutaneous adverse drug reactions (CADRs) are the commonest. They have been steadily gaining importance and constitute a major proportion of all ADRs. As available data on CADRs is very less, more research is required to have reliable data, hence the current study was undertaken. This prospective study was carried out to evaluate the age and gender distribution, presenting complaints, spectrum of CADRs, causative drugs, causality, severity, and outcomes in patients with or suspected CADRs attending the department of Dermatology of Konaseema Institute of Medical Sciences & Research Foundation Hospital between January 2014 and June 2015. In cooperation with the Dermatologist, patients’ reactions were analyzed based on morphology, and laboratory investigations. Causality was assessed as per the World Health Organization- Uppsala Monitoring Centre (WHO-UMC)causality assessment scale. Modified Hartwig and Siegel Scale was used for the severity assessment of reactions. CADRs occurred most commonly in the 31-40 years age group (32%) with no sign of the difference in both sexes. The most common complaint of CADRs by the patients was skin rash (42%) anddiagnoses were Erythematous drug eruption (ERDE) and Fixed drug eruption (FDE) (28%). The commonest causative drug categories were antimicrobials (52%) and Non-Steroidal Anti-inflammatory Drugs (NSAIDs) (24%).Among antimicrobials, ciprofloxacin, and in NSAIDs, diclofenac were the commonest causative drugs. In causality, majority of the cases were under possible category(42%). Most of the reactions were mild (46%), and moderate (46%) in severity. The majority of the cases showed good recovery without any mortality or disability. The limitations of this study were the relatively small sample size, inability to confirm the particular causative drug in majority of the patients. Future research should focus on the genetic factors concerning to CADRs and molecular-level evaluation should be done for a better understanding of the pathophysiology of various ADRs.

Published: July 2023

Imidazole heterocycles possess a very special place in biological chemistry making their derivatives receive considerable attention among researchers. Several natural products including nucleic acids, histamine, and histidine consist of the imidazole nucleus. It is an ionizable compound that renders good pharmacokinetic properties to the compounds contained in it. The nucleus presents some interesting pharmacological properties like antibacterial, antitubercular, anticancer, larvicidal, and antifungal. The present paper attempts to review the significant pharmacological actions of imidazole derivatives over the past few years. The paper summarizes the preparation methods like condensation method, microwave-assisted method, ultrasonic method and heating process employed for synthesis of imadazoles. The paper summarizes the current improvements of imidazole-based mixtures in the entire range of restorative science. The significant analysis of the published research infers that optimization of the microwave method for synthesis of the imidazole nucleus could be an effective method in the preparation of the motif.
Decolonizing imperialist discourse in Jane Austen’s Persuasion
Authors: Abd-Rabbo Muna , Zalloum Ghadir , Nemrawi Ziad
Published: July 2023

In his highly influential work Culture and Imperialism, Edward Said unravels the imperialist undertones in Jane Austen’s Mansfield Park. Throughout the chapter entitled “Jane Austen and the Empire,” Said demonstrates how this seemingly domestic novel of manners, not normally associated with imperialism, is actually densely saturated with colonialist discourse. For Said, the marginalized representation of the colonized territory of Antigua as simply a “colonial garden” for the British imperial patriarch further accentuates the superior sense of colonialist entitlement. Thus, Said’s approach in decolonizing the imperialist discourse in Mansfield Park may be extended to other canonical works not generally considered imperialist in nature. In this article, the researchers utilize Said’s strategies involved in his reading of Mansfield Park to probe the imperialist nuances in Austen’s Persuasion, a novel usually categorized as a romance/novel of manners which depicts two lovers’ second chance at happiness despite all the social obstacles in their way. The researchers attempt to foreground the imperialist rhetoric in this novel, specifically Austen’s tendency to romanticize and glorify the rising British naval society as the champions of the Empire. Furthermore, this article investigates the absent, peripheral representation of colonial terrains as opposed to the privileged, central position of the British Empire in the narrative.

Although it sparked a lot of attention from the media and the public at the beginning of its release in 1998, even today's e-reader devices do not automatically beat the popularity of printed books. It is due to the inability of e-readers to provide responsive features, and there are still many book fans who are happy with their own experience of reading printed books. This study aims to analyze how perception and usability affect e-reader user satisfaction. The population in this study are followers of Autobase Twitter @literarybase. This study uses non-probability sampling with a purposive sampling technique. The sample chosen is people who have had the experience of reading a book using an e-reader device. Conducted The research with quantitative methods using data from 132 respondents through the distribution of questionnaires with a Likert scale as primary data. The test uses a data instrument, correlation coefficient, classical assumption test, and multiple linear regression test. The real test is done with SPSS software. The results showed that each variable, Perception (X1) and Usability (X2), had the same effect, either partially or jointly, on the Consumer Satisfaction variable (Y). The conclusion shows readers do not have problems with old stereotypes and perceptions about reading activities that e-reader devices cannot present. The absence of a distinctive fragrance, attractive cover, page-turning activity, and many other things closely related to printed books did not eliminate the pleasure of respondents when using the e-reader device. Readers also view usability on e-reader devices as good performance, both in terms of features, navigation, and device responsiveness.

The vertical profile of optical turbulence is a key factor in the performance design of astronomical telescopes and adaptive optics instruments. As site-testing campaigns are extremely expensive, the selection of appropriate spatial resolution data and estimation methods is extremely important. This study investigated the effect of using different methods (Dewan, HMNSP99, Thorpe method) to estimate the refractive index structure constant (C
n
2) using different resolution data (5 m, 25 m, ERA5 data) in Huaihua, Hunan. Compared with Dewan, HMNSP99 for estimating C
n
2 using 5 m and 25 m resolution data, the Thorpe method almost always shows the best performance, with R
XY
above 0.75 and lower RMSE and MRE between estimated and measured C
n
2. The results of C
n
2 estimation using HMNSP99 at different resolution data varied widely, indicating that HMNSP99 is more sensitive to the data resolution and the temperature gradient is more sensitive to the resolution. Using ERA5 data, the two methods of estimating C
n
2 using Dewan and HMNSP99 have close results. It indicates that the wind shear is the main factor when the spatial resolution of the data is reduced to a certain degree, and the contribution of temperature gradient is small in the high altitude turbulence.

Published: July 2023

In this study, we propose the design of a surface acoustic wave (SAW) near-infrared sensor combined with an MXene quantum dot thin film to improve the infrared absorption efficiency at near-infrared wavelengths. A YZ-cut lithium niobate (LiNbO3) SAW resonator is fabricated as an infrared sensing unit with a resonant frequency shift reflecting the change in infrared radiation. It was observed that the responsivity of the near-infrared sensor (with a base frequency of 460 MHz) increased by approximately 88.89%. Thus, the proposed device exhibits high-performance infrared detection. Owing to the passive wireless capability of the device, it has wide applications.

Published: July 2023

In this work, we investigate possibility of engineering photonic density of states (PDOS) in photonic hypercrystals (PHCs). In the course of our analysis, we have demonstrated that it is possible to obtain photonic bandgap for selected polarization of light as well as to achieve significant broadband PDOS enhancement. We have also presented for the first time that anomalous dispersion, that arises from effective resonance of hyperbolic medium constituting the PHC structure, may lead to negative PDOS, which is photonic equivalent of mobility gap, observed in electronic crystals. Furthermore, we have demonstrated that application of PHC structure, instead of standalone hyperbolic medium, allows to obtain more versatile electromagnetic response, such as broadband perfect absorption of adjustable spectral range of operation.

Published: July 2023

Background

Women who use hormonal contraception face delayed return of fertility upon discontinuation. There was limited evidence of fertility return after hormonal contraceptive discontinuation in the study area. Hence this study assessed fertility return after hormonal contraceptive discontinuation and associated factors among pregnant women attending Family Guidance Association Ethiopia (FGAE) Dessie model clinic, Northeast Ethiopia, 2019.

Methods

A cross-sectional study was conducted on 423 samples selected by using systematic random sampling. Data were collected by face-to-face interview using a pretested and structured questionnaire and reviewing client records. Data were entered using Epi Data version 3.1 and analyzed using SPSS version 23. Both bi-variable and multivariable binary logistic regressions were used to identify predictors of delayed fertility return. Adjusted odds ratio (AOR) along with a 95% Confidence Interval (CI) was used to measure the strength and the direction of the association and statistical significance was declared at a P-value less than 0.05.

Result

The proportion of fertility return among currently pregnant women after discontinuation of any hormonal contraceptive methods was 88.6% (95% CI; (85.6%-92%)). The proportion of fertility return among Depo-Provera, implant, Intrauterine Contraceptive Device (IUCD), and Oral Contraceptive Pill (OCP) users was 75%, 99.1%, 100%, and 97.8% respectively. Age, (AOR = 5.37, (95% CI; (1.48, 13.6)) and using Depo-Provera (AOR = 4.82, 95% CI; (1.89, 14.2)) had a significant association with delayed fertility return.

Conclusions

The proportion of fertility return among women after discontinuation of any hormonal contraceptive methods was high. Age and using Depo-Provera had a positive association with delayed fertility return. This study recommends a contraceptive counseling approach that addresses concerns about delay in the return of fertility after hormonal contraceptive discontinuation to avoid confusion among family planning users.

Entrustable Professional Activities (EPA) are specialty specific tasks or responsibilities, combining the clinical workplace and the long-demanded competency-based medical education. The first step to transform time-based into EPA-based training is to reach consensus on core EPAs that describe sufficiently the workplace. We aimed to present a nationally validated EPA-based curriculum for postgraduate training in anaesthesiology. Using a predefined and validated list of EPAs, we applied a Delphi consensus approach, involving all German chair directors of anaesthesiology. We then conducted a subsequent qualitative analysis. Thirty-four chair directors participated in the Delphi survey (77% response) and twenty-five completed all the questions (56% overall response). Reflected by the intra-class-correlation, the consensus on the importance (ICC: 0.781, 95% CI [0.671, 0.868]) and the year of entrustment (ICC: 0.973, 95% CI [0.959, 0.984]) of each EPA reached high levels of agreement among the chair directors. The comparison of data assessed in the preceding validation and present study showed excellent and good levels of agreement (ICC entrustment: 0.955, 95% CI [0.902, 0.978]; ICC importance: 0.671, 95% CI [-0.204, 0.888]). The adaptation process, based on the qualitative analysis, resulted in a final set of 34 EPAs. We present an elaborate, fully described and nationally validated EPA-based curriculum, reflecting a broad consensus among different stakeholders of anaesthesiology. We hereby provide a further step towards competency-based postgraduate anaesthesiology training.

Achieving universal health coverage (UHC) is a priority of most low- and middle-income countries, reflecting governments’ commitments to improved population health. However, high levels of informal employment in many countries create challenges to progress toward UHC, with governments struggling to extend access and financial protection to informal workers. One region characterized by a high prevalence of informal employment is Southeast Asia. Focusing on this region, we systematically reviewed and synthesized published evidence of health financing schemes implemented to extend UHC to informal workers. Following PRISMA guidelines, we systematically searched for both peer-reviewed articles and reports in the grey literature. We appraised study quality using the Joanna Briggs Institute checklists for systematic reviews. We synthesized extracted data using thematic analysis based on a common conceptual framework for analyzing health financing schemes, and we categorized the effect of these schemes on progress towards UHC along the dimensions of financial protection, population coverage, and service access. Findings suggest that countries have taken a variety of approaches to extend UHC to informal workers and implemented schemes with different revenue raising, pooling, and purchasing provisions. Population coverage rates differed across health financing schemes; those with explicit political commitments toward UHC that adopted universalist approaches reached the highest coverage of informal workers. Results for financial protection indicators were mixed, though indicated overall downward trends in out-of-pocket expenditures, catastrophic health expenditure, and impoverishment. Publications generally reported increased utilization rates through the introduced health financing schemes. Overall, this review supports the existing evidence base that predominant reliance on general revenues with full subsidies for and mandatory coverage of informal workers are promising directions for reform. Importantly, the paper extends existing research by offering countries committed to progressively realizing UHC around the world a relevant updated resource, mapping evidence-informed approaches toward accelerated progress on the UHC goals.

Published: July 2023

Introduction

Many healthcare workers have switched from face-to-face clinical supervision to telesupervision since the onset of the COVID-19 pandemic. Given the rise in prevalence of telesupervision and continuing remote working arrangements, telesupervision is no longer only limited to rural areas. As this remains an under-investigated area, this study aimed to explore supervisor and supervisee first hand experiences of effective telesupervision.

Methods

A case study approach combining in-depth interviews of supervisors and supervisees, and document analysis of supervision documentation was used. De-identified interview data were analysed through a reflective thematic analysis approach.

Results

Three supervisor-supervisee pairs from occupational therapy and physiotherapy provided data. Data analysis resulted in the development of four themes: Benefits vs limitations and risks, not often a solo endeavour, importance of face-to-face contact, and characteristics of effective telesupervision.

Discussion

Findings of this study have confirmed that telesupervision is suited to supervisees and supervisors with specific characteristics, who can navigate the risks and limitations of this mode of clinical supervision. Healthcare organisations can ensure availability of evidence-informed training on effective telesupervision practices, as well as investigate the role of blended supervision models to mitigate some risks of telesupervision. Further studies could investigate the effectiveness of utilising additional professional support strategies that complement telesupervision, including in nursing and medicine, and ineffective telesupervision practices.
Fashion in motion: The Madchester movement (1985–96)
Authors: Atkin Susan
Published: July 2023

This article studies the effect and affect of clothing when moving (walking, posturing, dancing) during a seminal period of Manchester, England’s music scene from 1985 to 1996, known as Madchester. The research explores the links between the city’s music scene and local youth fashion at a time when there was a shift away from traditional notions of subcultures towards something more fluid and positions Madchester as a pivotal point where there was an egalitarian coming together of individuals and groups under the umbrella of what has become known as rave culture. The term ‘fashion in motion’ has been established in this research to define the interaction of garment and wearer in movement and its visual result. The article investigates how Mancunian men participating in the Madchester scene made sartorial choices to enhance and respond to movement. Findings are based on oral evidence in the form of active interviews with Madchester-era key players, supported by analysis of contemporary images.
Jaws, anthropocentrism and cinema as a monster-making machine
Authors: Mills Brett
Published: July 2023

Jaws() is a film in which a shark is depicted as a monster. Readings and analyses of the film routinely describe the shark as a monster, and pleasures associated with the film rest on audiences reading the animal as such. The book the film is adapted from constructs the shark in similar ways, but there are notable differences between the two. This article examines how the film constructs the shark as a monster, with particular reference to differences between the book and film. It focuses specifically on the story-telling and representational norms associated with each medium, indicating how cinema’s centring of the audio-visual is fundamental to its monster-making processes. Drawing on work from the ‘animal turn’ this article demonstrates cinema’s embedded anthropocentrism and points to the implications this has for non-humans outside of cinema.
The Reproachful Head of the Green Knight: Exploring the eerie, liminality, deep time and duration in ‘Sir Gawain and the Green Knight’
Authors: Eden Michael
Published: July 2023

The outcomes presented in this article represent a body of fine artworks that respond to the medieval poem ‘Sir Gawain and the Green Knight’ (c.1380), culminating in the realization of the monstrous head of the Green Knight. I outline influences from an extended base of film, and television, including direct adaptations of the poem, and thematically relevant sources that include analogous narratives; as well as looking at fine art sculpture and painting that have informed my making strategies. I also discuss my theoretical framing of the poem which asserts the Green Knight as an eerie agent of temporality. The relationship between liminal space and monstrous intrusion on the subject is explored, looking to French philosopher Henri Bergson and English writer and cultural theorist Mark Fisher to articulate the subjective implications of deep time manifested in monstrosity. The article charts the ways in which academic research has combined with studio practices to develop and enrich ideas, allowing for a dramatic error in production to become an attribute of a finished work.
Wendigo, vampires and Lovecraft: Intertextual monstrosity and cultural otherness in video games
Authors: Cowen André
Published: July 2023

Civilization has, since its inception, employed mythical or deified entities in place of the unknown. Folklore and mythology are the culmination of such beliefs, providing lessons or logic behind behavioural patterns within the society of the time, with the Epic of Gilgamesh (Anon. c.2100 BC) producing a narrative precedence that ‘[n]ature is the opposing pole of the human’. However, the roles of such tales, and hence their monsters, have adapted as humans came to understand more of the world around them. Tchaprazov suggests that Stoker’s Dracula (Stoker 1897) emphasizes ‘that the Slovaks stand both culturally and geographically opposite to the West’, producing social narratives relating to a cultural ‘Other’. Within this article I explore how monsters, based on regional folklore, within video game adaptations such as The Witcher: Enhanced Edition (CD Projekt Red 2008) and Metro 2033 Redux (4A Games 2014) are depicted as a nature-based ‘other’, especially as opposed to the player-character. Furthermore, I look at the cultural implications of contrasting modern depictions, such as the wendigo within Until Dawn (Supermassive Games 2015) and other transmorphic entities. Finally, I suggest that the intersection of culture and folklore within the ‘brickmaker’s village’ in The Witcher: Enhanced Edition is a hybridized adaptation which simultaneously adapts Lovecraft’s The Shadow over Innsmouth (Lovecraft 1931) and the Slavic folklore of the vodyanoy, whilst also challenging what Švelch calls a ‘conceptualization of monstrosity’.

Existem muitos conceitos de marketing relacionados a marcas que buscam estudar o comportamento do consumidor e como construir a fidelidade do consumidor a essas marcas. Muitos conceitos ligados à marca que derivam da área do marketing estão a ser utilizados na área do turismo (imagem de destino, personalidade do destino, identidade do destino, entre outros). O objetivo deste estudo exploratório é testar a escala do construto da experiência da marca do destino, ainda pouco analisado no contexto dos destinos turísticos. O método de estudo aplicado foi a metodologia quantitativa tendo a recolha de dados sido feita através da utilização de um inquérito por questionário. O território em análise foi a Peneda-Gerês, único parque nacional português e que tem registado um crescimento elevado de visitantes. Foram recolhidos 507 questionários válidos que foram posteriormente codificados. Foi possível observar que as experiências sensoriais se destacaram claramente, seguido das experiências afetivas. De salientar também que as experiências intelectuais não tiveram grande evidência, provavelmente pelo tipo de destino turístico.
A COVID-19 hatása a globális logisztikai folyamatokra
Authors: Gál József , Sós Máté
Published: July 2023

A Covid-19 világjárvány okozta ellátási lánc zavarai páratlan nagyságrendűek a körülmények egybefolyása miatt: a világjárványhoz kapcsolódó leállások, a geopolitikai helyzet, a munkaerőhiány, sőt az időjárás is jelentős hatást gyakorolt az ellátási láncokra szerte a világon. Hatásukra megfigyelhetők az alábbiak: az ellátási lánc szűk keresztmetszete, növekvő költségek és zavarok. Válaszul a szervezetek különféle stratégiákkal próbálkoznak: a szállítók megosztásával és vertikálisan integrált ellátási láncokkal. Megállapítható, hogy a járvány okozta változások rövidebbé és átláthatóbbá teszik a globális ellátási láncokat az olyan megújult stratégiák révén, mint a digitalizáció.
A szárított fodormenta tárolási tapasztalatai
Authors: Antal Tamás
Published: July 2023

A frissen betakarított fodormenta leveleket fagyasztva szárítással és ún. kombinált szárítási módszerekkel, azaz infravörös-fagyasztva szárítással és meleg levegős-fagyasztva szárítással dehidráltuk. A szárított anyagokat lezárt polietilén csomagokba helyeztük és 4 hónapig szobahőmérsékleten, polcon és hűtőberendezésben tároltuk. A levelek színvizsgálata és illóolaj-tartalmának analizálása havi rendszerességgel történt. A színvizsgálati eredményekből megállapítottuk, hogy a szobahőmérsékleten megőrzött fodormenta levelek teljes színeltérése magasabb volt, mint a hűtőbe helyezett mintáké. Különösen magas színdifferenciát azonosítottunk a liofilizált mintáknál. A hűtőben és polcon tárolt fodormenta levelekből extrahált összillóolaj kinyerésekor megállapítottuk, hogy szignifikáns eltérés nincs a két tárolási kondíció között, viszont az illóolaj összetevők megőrzésében a hűtőberendezésben tárolt levelek kedvezőbb értékeket produkáltak. Az eredményeinket figyelembe véve azt javasoljuk, hogy az infravörös-fagyasztva szárítással tartósítsuk a fodormentát a költséges liofilizálás helyett és a szárított mintákat szobahőmérsékleten raktározzuk.
