Authors: ARABACİOGLU DİLAN , BALIKÇIOĞLU DEDEOĞLU SEVGİ , İLHAN İBRAHİM
Published: May 2024

The current study aims to determine the effects of technology leadership by tourist agencies on the motivation of tour guides to engage in professional sharing behaviors on social media. The data for this study were collected through surveys from registered tour guides affiliated with a travel agency in Turkey. In total, 373 participants were reached. Partial least squares-structural equation modeling was used to examine the mediating role of motives for social media use in the effect of travel agencies’ technology leadership on tour guides’ Instagram use behaviors. The findings showed that the technology leadership of travel agencies affects the Instagram use behaviors of tour guides and that the motivation for social media use has a mediating role in this relationship. According to our research findings, as guides become more proficient in using Instagram, their reputation among individuals improves. Consequently, the number of professional posts and the visibility of guides on social media will increase, making them more appealing to a larger number of tourists. This study differentiates itself from others related to technology leadership in the literature, as it is the first to mention both technology leadership and tour guides’ social media usage together.

Published: May 2024

Human adaptation to physical activity is manifested through mobilization of functional reserves. The purpose of this study was to provide a scientific and experimental substantiation of the adaptation of functional reserves of the motor system in athletes to specific sports activities from the standpoint of the physiological and biomechanical approach. Materials and methods. The study involved 704 elite athletes doing various sports. Reaction time was determined using the hardware and software package “Sports Psychophysiologist”. Stabilometric parameters were analysed using stabilometric platforms with the Smart BTS Motion System (BTS Bioengineering, Italy); the static analysis test protocol was applied. Electromyographic and biomechanical (kinematic and dynamic) movement control was performed using the Smart BTS Motion System as well. Functional reserves of the motor system were studied in line with the existing ideas about the components of the human body’s physiological reserves activated when doing sports. The following were evaluated: sensory systems (sensorimotor reactions, vestibular stability), movement control (stabilography, kinematics, dynamics), regulation of homeostasis, and implementation of activity (neuromuscular system). Results. We found that both single (in respect of urgent adaptation: an increase in voltage, optimization of kinematics and dynamics during a weightlifting snatch) and systematic (as regards long-term adaptation: improvement in reaction time and vestibular stability in athletes of various sports) training sessions involving maximum strength, power and speed contribute to the activation of the relevant sensory systems, central nervous system and muscular system, which form the basis of the motor system and increase its functionality as a whole.

A hierarchical signal detection model with unequal variance for binary responses
Authors: Lages Martin
Published: May 2024

Gaussian signal detection models with equal variance are commonly used in simple yes–no detection and discrimination tasks whereas more flexible models with unequal variance require additional information. Here, a hierarchical Bayesian model with equal variance is extended to an unequal-variance model by exploiting variability of hit and false-alarm rates in a random sample of participants. This hierarchical model is investigated analytically, in simulations and in applications to existing data sets. The results suggest that signal variance and other parameters can be accurately estimated if plausible assumptions are met. It is concluded that the model provides a promising alternative to the ubiquitous equal-variance model for binary data.
Estimating statistical power for structural
equation models in developmental cognitive science: A tutorial in R
Authors: Buchberger Elisa S. , Ngo Chi T. , Peikert Aaron , Brandmaier Andreas M. , Werkle-Bergner Markus
Published: May 2024

Determining the compositional structure and dimensionality of
psychological constructs lies at the heart of many research questions in
developmental science. Structural equation modeling (SEM) provides a versatile
framework for formalizing and estimating the relationships among multiple latent
constructs. While the flexibility of SEM can accommodate many complex assumptions on
the underlying structure of psychological constructs, it makes a priori estimation
of statistical power and required sample size challenging. This difficulty is
magnified when comparing non-nested SEMs, which prevents the use of traditional
likelihood-ratio tests. Sample size estimates for SEM model fit comparisons
typically rely on generic rules of thumb. Such heuristics can be misleading because
statistical power in SEM depends on a variety of model properties. Here, we
demonstrate a Monte Carlo simulation approach for estimating a priori statistical
power for model selection when comparing non-nested models in an SEM framework. We
provide a step-by-step guide to this approach based on an example from our memory
development research in children.

Reflections on the Research of Chinese Christian’s View of Suffering Based upon Fusion of Horizons: Understanding and Reviewing “Research on Christian’s View of Suffering”
Authors: Weiping Wang
Published: May 2024

Humans have always tried to understand suffering as a condition of existence, and grasping the notion of suffering is central to understanding a culture. "A Study of the Christian Concept of Suffering" employs the method of religious anthropology to explore the Christian understanding of suffering from the dimensions of reason, faith, and reality, revealing that the actual concept of suffering among Chinese Christians is a result of the integration of Chinese traditional culture with Christian cultural perspectives. Comparing the understanding of suffering in traditional Chinese culture with that in Christianity, based on this Fusion of Horizons, will deepen and advance the study of the problem of suffering and holds significant theoretical and practical importance for the sinicization of Christianity.
Form is the Essence: The Characteristics of Russian Orthodoxy in the Light of its Liturgy
Authors: Zhijun Wang
Published: May 2024

Russian Orthodoxy has the double meanings of Right Faith and Right Worship. In the light of Roman Catholic and Protestant Churches, the relationship between Shamanism or polytheism and Orthodoxy has been overemphasized, and such an opinion will hinder people from understanding the essence of Orthodoxy. The divine beauty, the relationship between worship and theology, and mysticism have been expressed outwardly. The divine beauty of Orthodox churches and icons is the extension of the ceremony of worship, and the Orthodox ceremony of worship is the resource of theology and the revelation of God, and the liturgy of Orthodoxy has been full of mystic imagination.

Published: May 2024

With the advent of automation, the concept of protecting the business environment has become popular and recognized in the business world. As the factory scale grows and the complexity of the process increases, advanced technology must be used in the device to measure and control many business processes simultaneously. Today, the trend is towards miniaturization of instruments and greater precision and accuracy. Reliable equipment and controls are crucial to the safety and efficiency of any process. The goal of this project is to gain knowledge about the most important aspects of the job to improve safety. The system includes the use of LORA to monitor the business environment. In this project, we use Lora communication to send data, and the receiving end of the monitoring station receives the data from the sending end. In an emergency, when you press the emergency button on the monitoring station, a message is sent to the work unit by LORA. Since LORA is a transceiver, two- way communication is possible in the project. Temperature sensors, gas sensors and fire sensors are used to monitor the environment of business units. Temperature sensors are used in industry to calculate temperature and provide information to microcontrollers. Gas sensors are used in industry to detect gas leaks. Fire sensors are used to detect fire and send the information to the monitoring station. This product is delivered by LORA.

Lichen planopilaris (LPP) is an inflammatory variant of primary cicatricial alopecia. It causes severe hair loss and can lead to complete baldness. It is an autoimmune disease and can affect patients’ physical and mental lives greatly. JAK Inhibitors have been proven the most effective treatment option to treat LPP. This literature review aimed to analyze the effectiveness of JAK inhibitors in the management of LPP. In this review, we analyzed the ten most recent and comprehensive studies. The review has summarized existing case reports from clinical studies that have supported JAK inhibitors. The findings of the review show that JAK inhibitors are effective options for the treatment of LPP, however, there are still some concerns regarding the long-term safety of these drugs in the treatment of LPP. This review also highlights potential gaps in the literature and further need for research. Currently, there is a need for further research on the effectiveness of JAK inhibitors in the treatment of LPP.
PRICE RECALCULATION MODEL OF CONSTRUCTION CONTRACTS
Authors: Vilkonis Arvydas , Antuchevičienė Jurgita
Published: May 2024

In recent years, the world economy has experienced rapid economic change in the construction sector and record inflation. The rapidly rising prices of construction materials and machinery in the construction market are also pushing up the cost of construction services. The main problem is that construction projects have been drawn up and contracts between clients and contractors have been awarded at previous prices, and it is therefore necessary to look for opportunities to index the price of construction contracts. The aim of the study is to propose a mathematical model and a smartphone application for the price recalculation of construction projects. The success of a construction project depends on the correct decisions taken at the stage of preparation and implementation of the procurement documents for construction contracts, a complex process requiring a lot of legal and technological knowledge. The proposed mathematical model would help clients and contractors to carry out the calculation of the price according to the construction price index quickly and without the need for extensive specialist technical expertise. The mathematical model is adapted to smartphones with Android software.

Dense outflowing gas, traced by transitions of molecules with large dipole moment, is important for understanding mass loss and feedback of massive star formation. HCN 3-2 and HCO+ 3-2 are good tracers of dense outflowing molecular gas, which are closely related to active star formation. In this study, we present on-the-fly mapping observations of HCN 3-2 and HCO+ 3-2 toward a sample of 33 massive star-forming regions using the 10-m Submillimeter Telescope. With the spatial distribution of line wings of HCO+ 3-2 and HCN 3-2, outflows are detected in 25 sources, resulting in a detection rate of 76%. The optically thin H13CN and H13CO+ 3-2 lines are used to identify line wings as outflows and estimate core mass. The mass M

Published: May 2024

Cette étude vise à tester l’efficacité d’un dispositif pédagogique d’acquisition de l’orthographe lexicale des mots en CP. Les élèves ont appris à écrire les mots au cours de séances brèves et espacées dans le temps jusqu’à ce que quatre formes orthographiques correctes d’un mot soient produites. Les mots appris ont ensuite été évalués en condition isolée, insérés dans des phrases ou produits à partir d’images. Les performances des élèves ont été comparées à celles de groupes contrôles. Les résultats confirment le bénéfice d’un entrainement par réapprentissages successifs espacés dans le temps avec retours immédiats, principalement pour les mots complexes : inconsistants (ou irréguliers) et longs. L’intérêt d’un tel dispositif est discuté dans le but de proposer un enseignement de l’orthographe lexicale plus individualisé.

Epidemiology of cycling road injuries-related deaths
Authors: Mattiuzzi Camilla , Lippi Giuseppe
Published: May 2024

Dear Editor,
 
There are now several lines of evidence that millions of people around the world use bicycles as a routine means of transportation. In the US alone, for example, the website Statista estimates that 55 million people use bicycles as a primary or complementary mode of transportation, with a trend that has been steadily increasing over the past decade. In addition to the positive environmental impact of cycling as an alternative means of transportation for reducing pollution, cycling also offers numerous health and wellness benefits. Nevertheless, cycling injuries on the road are still a primary health concern, as collisions with motor vehicles or accidental falls can cause serious harm to cyclists. [...]
Healthcare-seeking behavior and spatial variation of internal migrants with chronic diseases: a nationwide empirical study in China
Authors: Li Dan , Gao Dawei , Yamada Masaaki , Chen Chuangbin , Xiang Liuchun , Nie Haisong
Published: May 2024

Individuals migrating with chronic diseases often face substantial health risks, and their patterns of healthcare-seeking behavior are commonly influenced by mobility. However, to our knowledge, no research has used spatial statistics to verify this phenomenon. Utilizing data from the China Migrant Dynamic Survey of 2017, we conducted a geostatistical analysis to identify clusters of chronic disease patients among China’s internal migrants. Geographically weighted regressions were utilized to examine the driving factors behind the reasons why treatment was not sought by 711 individuals among a population sample of 9272 migrant people with chronic diseases. The results indicate that there is a spatial correlation in the clustering of internal migrants with chronic diseases in China. The prevalence is highly clustered in Zhejiang and Xinjiang in north-eastern China. Hotspots were found in the northeast (Jilin and Liaoning), the north (Hebei, Beijing, and Tianjin), and the east (Shandong) and also spread into surrounding provinces. The factors that affect the migrants with no treatment were found to be the number of hospital beds per thousand population, the per capita disposable income of medical care, and the number of participants receiving health education per 1000 Chinese population. To rectify this situation, the local government should “adapt measures to local conditions.” Popularizing health education and coordinating the deployment of high-quality medical facilities and medical workers are effective measures to encourage migrants to seek reasonable medical treatment.
Colistin, the last resort antibiotic: challenges in the implementation of its routine susceptibility testing
Authors: Goyal Nisha , Gangar Seema , Sarkar Krishna , Singh Narendra Pal , Das Shukla , Dwivedi Aditya Nath
Published: May 2024

Background: colistin has become a critical antibiotic for lifethreatening multidrug resistance Gram-negative infections, particularly carbapenemase-producing bacteria. Detecting colistin resistance in routine microbiology laboratories is crucial for combating these fatal infections poses a challenge. Especially in developing countries, there is a need for a cost-effective, rapid, and user-friendly diagnostic method. Objective: implementing the various available methods for colistin testing is a significant challenge in resource-limited settings due to logistic difficulties and the need for technical expertise. Materials and Methods: this study shares experiences and insights gained while implementing in-vitro colistin susceptibility testing in a high-load bacteriology laboratory of a tertiary care center in Delhi, India. The following test methods for colistin susceptibility testing were incorporated in the routine antimicrobial susceptibility testing of our laboratory: Colistin Agar Test, Colistin Broth Disk Elution Test, Broth Microdilution susceptibility testing. Results: inconsistent growth patterns were observed in the colistin agar dilution Minimum Inhibitory Concentration (MIC) method, which could be resolved only after the preparation of fresh plates containing that specific concentration of colistin. The contamination issue of plates on use over a few days was addressed by pouring agar containing various concentrations of colistin in cottonplugged glass tubes. In the colistin broth disk elution test, due to the non-availability of screw-capped 10 mL glass tubes, MacCornety bottles (30 mL) were used. Subcultures were performed from the turbid wells to rule out the growth of contaminants when encountering discordant MIC values or skipped wells on the colistin broth microdilution test. Conclusions: despite several technical issues in in-vitro colistin susceptibility testing, we have successfully implemented it in our laboratory. Our experiences can offer guidance to laboratories that are still in the process of implementing it.

Quality use of medicines: The elderly patients with Osteoarthritis
Authors: Gray A.
Published: May 2024

Osteoarthritis (OA) is an exceedingly common diagnosis in family practice, particularly in the elderly population. It is certainly the most common of the artritides, but differs substantially in that inflammations, if present, is usually mild and restricted to the affected joint(s). The causes are not as yet completely understood and there is no known cure. Taken together, this means that a large proportion of elderly patients, in whom concurrent morbidities are common and who are at increased risk of receiving multiple, potentially inappropriate medicines, will most probable require pain relief of some sort.

The difficult patient: An attachment perspective
Authors: Panzer A. , Viljoen M. , Maunder R.G. , Hunter J.J.
Published: May 2024

Stressors such as illness, injury and hospitalisation are likely to accurate attachments behaviours. The way people react to these stressors (i.e their illness behaviour); varies widely; and is strongly correlated with their attachment style. In this paper we briefly review attachment theory, with reference to difficult patient behaviours, including compulsive self-reliance, compulsive care seeking and rejection of staff coupled with exaggerated help-seeking behaviour. We conclude by suggesting simple interventions that can easily be applied to enable staff to cope, and thus be more able to help patients with difficult illness behaviours.
Effect of soft liner on clinical implication of tooth supported overdenture
Authors: Elawady Ayman F. , Eissa Sherihan M. , Esmat Ahmed M.
Published: May 2024

Background/aim

Overdentures are considered as the most preferred treatment modality in patients with few remaining teeth, especially after using different denture liners. The present study aims to compare between the clinical performance of tooth supported overdentures relined with three different types (hard denture liner, silicon soft liner, and acrylic resin based soft liner) regarding modified bleeding index, probing depth, and patient satisfaction.

Patients and methods

A total of 21 partially edentulous patients with one remaining tooth on each side received overdentures constructed with conventional method after abutment preparation. Then dentures were classified randomly into three groups according to relining material: group I was relined with hard liner, group II was relined with silicon soft liner, and group III was relined with acrylic resin soft liner. All patients were recalled after 1, 3, and 6 months. At recall visits, assessment of the oral health status was performed by measuring probing depth and modified bleeding index by using periodontal probe. Moreover, patient satisfaction was evaluated using Oral Health Impacts Profile-14 questionnaire.

Results

One-way analysis of variance (ANOVA) was performed to compare among the three groups, which revealed significant difference between them in all follow-up periods regarding modified bleeding index, probing depth, and patient satisfaction, followed by Tukey’s post-hoc test for multiple comparisons, which revealed a significant difference among all groups (P<0.05). On the contrary, comparison was performed between different follow-up periods in each group by repetitive one-way ANOVA test, which revealed a significant difference in all groups regarding modified bleeding index and probing depth, whereas revealed insignificant difference in patient satisfaction. Repetitive one-way ANOVA test was followed by Tukey’s post-hoc test for multiple comparisons, which revealed significant difference between T1 and T2 and between T1 and T3 in all groups regarding modified bleeding index, whereas revealed a significant difference between T1 and T3 in all groups regarding probing depth, but in patient satisfaction, insignificant difference was revealed.

Conclusion

Acrylic resin soft liner showed the best clinical performance then silicon soft liner followed by hard liner regarding modified bleeding index, probing depth, and patient satisfaction during the follow-up period.
Genetic analysis of Turner syndrome in Tunisian patients
Authors: Siala-Sahnoun Olfa , Laadhar Fatma , Mnif Mouna , Sefi Wajdi , Kacem Faten Hadj , Kessentini Mohamed A. , Abid Mohamed , Fakhfakh Faiza
Published: May 2024

Background/aim

Turner syndrome (TS) is a rare sex chromosome abnormality in women, occurring in approximately one in 2500 live births, associated with a wide range of clinical stigmata of which short stature, ovarian dysgenesis, and dysmorphic features are the most frequent. Morbidity and mortality are clearly increased compared with the general population, and the average age at diagnosis is quite delayed. Even if the majority of females with TS have a non-mosaic 45,X karyotype, several karyotype variations exist, including short or long arm deletion, ring X isochromosome of the long arm, and 45,X 46,XX mosaicism. This explains the large phenotypic and genetic heterogeneities of TS, which make the diagnosis and especially the management increasingly difficult. We present in this work a genetic study of TS in the Tunisian population to establish a genotype–phenotype correlation, which would be of great help for the diagnosis and the care of patients.

Patients and methods

A total of 26 unrelated Tunisian girls were included in this study. All patients underwent a complete clinical and biochemical examination as well as karyotyping. The screening for the SRY gene was carried out by fluorescence in-situ hybridization or by PCR.

Results

Cytogenetic results showed a prevalence of the 45,X karyotype in 46% of patients and various proportions of the other karyotypes. However, genotype–phenotype correlation revealed several discrepancies regarding the major signs and the age at diagnosis. The comparison of the approaches used for the screening of the SRY gene showed that karyotyping is unable to detect low 45,X/46,XY mosaicism and that it is the PCR that would be able to do, eliciting its role to make a reliable diagnosis.

Conclusion

The karyotype alone is not sufficient to make a TS diagnosis in cases of weak mosaicism, and the great heterogeneity that reigns the syndrome elicits an epigenetic and transcriptomic exploration of several genes that recently seem to be involved in the disease.
Correlation of serum chitinase-3-like protein 1 level with cardiovascular complications in Egyptian patients with type 2 diabetes mellitus
Authors: El-Wakeel Mervat E. , Bazeed Mariam H. , Shrief Hala M. , Ghanem Ayat I.
Published: May 2024

Background/aim

Diabetes mellitus (DM) represents a strong as well as independent risk factor toward cardiovascular diseases (CVDs), considered to be the primary reason for morbidity and mortality linked to type 2 diabetes mellitus (T2DM). DM may alter the production of many inflammatory cytokines, including chitinase-3-like protein 1 (CHI3L1). The present study aims to evaluate the correlation of serum level of CHI3L1 with cardiovascular complications in Egyptian patients with T2DM.

Participants and methods

A total of 90 participants were enrolled in this case–control study (age range 40–70 years). They were divided into three groups: Group 1, which included 30 T2DM patients with CVDs; group 2, which included 30 T2DM patients without CVDs; and group 3, which included 30 individuals as a control group. Comparison of groups in terms of demographic, laboratory, echocardiography, carotid intima-media thickness, and serum CH3L1 levels was carried out for all participants.

Results

CHI3L1 was statistically found to be highly statistically significant in group 1 over group 2 (P<0.001) and in group 2 over group 3 (P<0.001). CHI3L1 was positively correlated with the duration of DM (r=0.009; P=0.049), triglyceride (r=0.866; P=0.001), low-density lipoprotein cholesterol (r=0.950; P=0.001) and albumin/creatinine ratio (r=0.386; P=0.002), while a negative correlation existed with high-density lipoprotein cholesterol. (r=−0.408; P=0.024). On drawing an receiver operating characteristics curve between groups 1 and 2, the CHI3L1 cutoff point was less than or equal to 67.38 µg/l, and the area under the curve was 0.9193 (P=0.001) with 100% specificity and 60% sensitivity.

Conclusions

CH3L1 has better specificity and positive predictive value in the differentiation between T2DM patients with cardiovascular complications and those without cardiovascular complications, which may add a new diagnostic biomarker for early detection of CV complications, proposing new efficient therapies for such patients.

Authors: El Naggar Shady M. , Helal Eman , Khalil Mai F.F. , Esmat El-Sisy Ahmed M. , Gouda Ayman
Published: May 2024

Background/aim

Implant-supported prostheses proved to solve a lot of problems and difficulties associated with edentulism, yet some complications continued to appear after using the different modalities of implant-supported prostheses, so this study aimed to count and analyze the possible prosthetic and biological complications of implant-retained fixed versus removable overdentures.

Patients and methods

The study was conducted on 22 completely edentulous patients selected from the Outpatient Clinic of Prosthodontic Department, Faculty of Oral & Dental Medicine, Badr University, Egypt. They were distributed randomly into two groups: group I received implant telescopic overdentures, group II received fixed detachable screw-retained implant-supported prostheses, and prosthetic and biological complications were evaluated after 1, 3, and 6 months.

Results

The present results indicated that Χ
2 test was performed for significance evaluation between both groups in biological and prosthetic complications. In biological complications, it revealed a significant difference in relining after 6 months between both groups as P value less than 0.05. While for prosthetic complications, there was a significant difference between both groups in tooth wear and tooth separation after 6 months as P value less than 0.05.

Conclusion

Regarding prosthetic complications, telescopic overdenture showed a higher incidence than hybrid fixed screw-retained screw looseness and screw fracture.

Background/aim

Fibroblast activation protein (FAP) as one of the complex tumor environment is expressed in activated fibroblasts and associated with poor prognosis in cancer. FAP expression in colon cancer lacks sufficient evidence to serve a significant role in angiogenesis. This study aimed to clarify the association of FAP expression with angiogenesis in the prognosis of colorectal carcinoma (CRC).

Materials and methods

A total of 50 biopsies of CRC were evaluated by immunohistochemistry for investigating FAP expression and microvascular density (MVD) using CD34 protein. In terms of FAP-positive cells and FAP staining intensity, tumors were classified as high and low expression. With respect to tumor vascularity, cases were classified into hypovascular tumors and hypervascular ones. Both of FAP expression and MVD were correlated with histological tumor grade, stage, and lymph node metastases and also with each other.

Results

FAP expression was significantly higher in malignant cases than normal nontumor tissue samples. The percentage of FAP-positive cells was significantly correlated with grade, T-stages, and lymph node metastases, while FAP intensity was significantly associated with high tumor stage only. Hypervascularity was significantly correlated with high T-stages and lymph nodes metastasis. A significant correlation was found between FAP expression percentage and MVD.

Conclusion

This study indicates that FAP is overexpressed in primary CRC and is associated with poor prognosis. The authors suggested that FAP may be used as a prognostic marker and could be reliable for predicting the angiogenic activity of CRC. Further studies are recommended applying FAP as a diagnostic marker for CRC and for evaluating its promising role as an excellent target for antitumor therapy.
О полностью нерегулярной маркировке без пропуска меток для некоторых планарных графов
Authors: Mitra Sarbari , Bhoumik Soumya
Published: May 2024

Полная нерегулярная $k$-разметка графа $G=(V,E)$, $\partial\colon V \cup E\rightarrow\{1, 2, 3,…,k\}$ - это набор меток, приписанных вершинам и ребрам $G$ таким образом, что веса всех ребер различны. Полная реберно-нерегулярная мера графа $G$, обозначаемая $\operatorname{tes}(G)$, определяется как минимальное значение $k$, при котором граф $G$ имеет полную реберно-нерегулярную $k$-разметку. Аналогично можно определить полную вершинно-нерегулярную меру графа $G$, обозначаемую $\operatorname{tvs}(G)$. В статье найдены полные реберно-нерегулярные и вершинно-нерегулярные меры без пропусков весов для некоторых хорошо известных планарных графов.

A fenntarthatósági nevelés aktuális kérdései : Egy nemzetközi felmérés előtt
Authors: Murányi Zoltán , Kovács Mihály
Published: May 2024

Egy projekt keretében olyan felmérésre készülünk, melynek során a világ legkülönbözőbb sarkaiban dolgozó középiskolai kémiatanárokat kérdezik meg arról, hogy hogyan illesztik a mindennapi oktatásba a zöld és fenntartható kémia elemeit, különös tekintettel a gyakorlati munkára. A felmérés előzeteseként kísérletet teszünk a jelenlegi hazai helyzet körvonalazására, és néhány számunkra érdekes kérdést is megfogalmazunk. A kérdőívek tapasztalatai alapján összevethetjük majd a válaszadók helyzetértékelését az általunk megfogalmazottakkal, és ami még fontosabb, betekintést nyerünk más európai és Európán kívüli nemzetek e témával kapcsolatos gyakorlatába. Utóbbit – a megosztott jógyakorlatokon keresztül – mindenki megteheti majd a projekt honlapján. Továbbá ezek elemzése, hazai viszonyokra adaptálása is jelentős munkának ígérkezik.
A levelező tagozatos szakmatanár szakos hallgatók által legszívesebben alkalmazott módszerek
Authors: Kovácsné Duró Andrea
Published: May 2024

Az oktatási módszerek kérdésköre napjainkban ismételten az érdeklődés középpontjában áll, hiszen az újabb tanulói generációk a korábbiaktól eltérő tanulási helyzeteket igényelnek. Ennek következtében pedig a pedagógusok módszertani repertoárjának gazdagítása is elengedhetetlen. Empirikus kutatásom során ezért egyéni kérdőíves vizsgálattal a levelezős szakmatanár szakos hallgatók által a tanórákon szívesen alkalmazott módszereket szándékoztam feltárni. Az eredmények azt mutatták, hogy a tanárjelöltek leginkább a szemléltetést, illetve a játékot és a kooperatív módszert kedvelik. Az egyes módszerekhez fűzött elemzések azonban nem elég részletesek, kevés személyes példával alátámasztottak. Ebből adódóan a képzés során nagyobb szerepet kell szánni a többféle tanulási modalitást lehetővé tevő metodikák alkalmazására való felkészítésnek, valamint az önreflexiós képesség fejlesztésének.
A Debreceni Szakképzési Centrum oktatói humán erőforrásának vizsgálata a megújult szakképzési rendszer és vállalati partnerintézmények kooperációja révén
Authors: Sütő Attila
Published: May 2024

Az utóbbi évek fő hajtóereje a munkaerőpiac igényeihez rugalmasabban alkalmazkodó és magas színvonalú szakképzési rendszer kialakítása volt. A rohamosan fejlődő gazdaság elvárása a jól képzett és felkészült szakemberek kitermelése, akik eleget tesznek a munkaerőpiaci elvárásoknak.1 A szakképzésben dolgozó oktatók számára komoly szakmai és emberi kihívást jelent a megfelelés. A téma nemzetközi kutatásának elhanyagoltságát részben a szakképzés általánosan alacsonyabb társadalmi státusza magyarázhatja (Hanushek, 2016), de jelentős az országos szintű oktatóhiány is (Bükki, 2022). Ezek a gondolatok sarkalltak a jövőbeni kutatásaim tervezése során, amelyek értelmében a Debreceni Szakképzési Centrum (DSZC) partnerintézményeiben vizsgálnám az oktatók pályaelégedettségét, a pályakezdő fiatal oktatók pályamotivációját, illetve a duális képzőhelyek eredményességét.
Szülői alkoholizmus felnőtt gyerekekre gyakorolt hatása
Authors: Pirisi Edina Enikő
Published: May 2024

A szülői alkoholizmus következtében olyan diszfunkcionális családi működés alakul ki, amely negatív hatással van a gyermek egészséges személyiségfejlődésére, lelki problémákhoz és az ACoA-szindróma kialakulásához vezethet. Az AcoA-szindróma egy olyan poszttraumatikus stresszzavar, amelyben az alkoholista családokban megélt traumatikus élmények, a megoldatlan gyerekkori sérelmek évekkel vagy évtizedekkel később a felnőtt kapcsolatokban tudattalanul aktualizálódnak és visszatérnek. Az alkoholisták felnőtt gyermekeinél ellehetetlenül a saját érzéseiknek és gondolataiknak a megélése és tudatosítása, nehézzé válik a megfelelő önszabályozás és a társukhoz való intim kapcsolódás. Az AcoA-szindrómás felnőttek számára a személyes problémáik megoldásához, illetve pszichés zavaraik kezeléséhez szükséges a megfelelő lelki segítségnyújtás, amelynek mind a paraprofesszionális, mind a professzionális formái hatékony támogatást tudnak nyújtani a nehézségekkel való megküzdésben.

Published: May 2024

A literature review and analysis evaluating how the practices of Intimacy Choreography support the aims of one of the Catholic Church's sexual abuse prevention programs collectively called VIRTUS. This article defines scenarios of legally unacceptable risk (high stakes) as well as legally acceptance risk (low stakes) and how the tools of Intimacy Choreography (Theatrical Intimacy Education, in particular) and VIRTUS both aim to establish and uphold boundaries, but in different capacities. This article compares the tools of each area, and makes an argument for how Intimacy Choreography's consent-based practices are a good for Catholic diocesan schools' theatre programs that utilize VIRTUS training.
