Authors: Makanda Isaac H. , Mushema Beata N. , Chuwa Salvatory P. , Chiduo Monica
Published: December 2023

Introduction: Endometriosis is characterised by endometrial tissue outside the endometrial cavity. The implantation sites may be pelvic or extrapelvic in nature. Umbilical endometriosis is a rare type of cutaneous endometriosis, accounting for 0.5-1% of extrapelvic endometriosis cases. Current literature on umbilical endometriosis is absent in the Tanzanian population. Case Report: A 30-year-old woman with prior caesarean deliveries presented with a 3-year history of umbilical swelling, cyclical pain, and menses-related bleeding. Examination revealed a firm brown umbilical lesion measuring 5x4centimetres (cm). Wide excisional biopsy was performed. Histopathological examination confirmed endometriosis and ruled out malignancy. The postoperative follow-up revealed no signs of recurrence. Conclusions: This case report highlights the need for high clinical vigilance and comprehensive differential diagnosis, especially for recurring and cyclical abdominal symptoms. Despite resource limitations, accurate diagnosis and appropriate treatment can result in the successful management of this rare condition. The report emphasises the urgency for clinicians to boost awareness, promote research, and advocate for better resources to ensure optimal patient outcomes.
Combating the debt load of the population in Russia
Authors: Molodyko Kirill
Published: December 2023

I summarize the current regulatory decisions aimed at combating the debt load of the population in Russia. Further, I show that the level of delinquency of the population on loans is growing despite the regulatory measures taken. In my opinion, the basis of regulatory policy should move from de facto pushing personal bankruptcies to preventing them. I put forward a hypothesis and statistically prove the expediency of quantitative restrictions on one borrower. It is necessary to introduce reports to the credit bureaus of some types of overdue debts, which are not actually reported now. It is also necessary to change the order of debt repayment established by law, allowing the principal and current interest to be paid first, which will prevent the expansion of the debt.

Published: December 2023

Immune checkpoint inhibitors (ICIs), such as nivolumab, which target anti‐programmed cell death-1 (PD-1), have been applied to a variety of cancers and have caused immune‐related adverse events (irAEs). Although an association between ICIs and bullous pemphigoid and mucosal pemphigoid (MMP) has been reported, the complex mechanisms underlying PD-1 inhibition‐induced autoantibody production and autoimmunity remain unelucidated. In this report, we present a unique case of MMP involving the palmoplantar lesions during adjuvant nivolumab therapy. A Japanese woman in her 70s was treated with nivolumab for postoperative vulvar malignant melanoma; after the 12th cycle of treatment, ulcers were seen in the oral cavity, and 4 months later, tense palmoplantar blisters appeared. Microscopic examination of the palmar blister revealed subepidermal vesicles characterized by eosinophil infiltration. Immunofluorescence analysis revealed linear IgG and C3 deposits along the basement membrane; ELISA testing confirmed the presence of anti‐BP180 NC16A IgG antibody, and MMP was diagnosed. The patient’s condition gradually improved with a therapeutic regimen of corticosteroids and immunoglobulins. A review of 10 cases of ICI‐associated MMP, including the present case, revealed clinical similarities to conventional MMP; in cases of persistent oral erosions due to ICI, it is most important to consider mucositis and MMP in the framework of differential diagnosis. Besides, we suggest that we can be more suspicious of MMP by paying attention to examining the palms and soles when the patient receiving ICIs has refractory oral ulcers. This report underscores the importance of careful observation and prompt management of irAE as cancer immunotherapy evolves.
The Relationship between Information Literacy and Academic Achievement in Online Learning: Focusing on the Mediating Effect of Self-regulation and Gender Differences
Authors:   Korea Univ. Institute of Educational Research, Beik Ah-rong , Kim Hye-Bin , Jo Il-Hyun
Published: December 2023

The purpose of this study is to explore gender differences and the mediating effect of self-regulation in the relationship between university students' information literacy and academic achievement in online learning. SEM and multi-group analysis were used by university students’ responses from 2020(12th) of the Korean Education Longitudinal Study 2005(KELS 2005). The study found that university students' information literacy directly affects academic achievement, and the mediating effect of self-regulation was significant between information literacy and academic achievement. In addition, the effect of information literacy on self-regulation was found to be significant in both males and females. This means that information literacy has a positively significant effect on self-regulation regardless of gender. Finally, it was confirmed that there was no difference between genders in the mediating effect of self-regulation, but the effect of self-regulation on academic achievement was higher in women. The results of this study suggest to accomplish academic achievement in online learning, it is necessary to strengthen self-regulation through the improvement of learners' information literacy, and in particular, continuous education and support are required to cultivate information literacy.
questão de terras no Contestado
Authors: Machado Paulo Pinheiro
Published: December 2023

Este artigo reflete sobre o peso, a relevância e o momento da manifestação da questão agrária no movimento do Contestado, considerando a diversidade regional alcançada pela expansão do movimento sertanejo e as diferentes naturezas de conflitos agrários em curso antes e durante a Guerra do Contestado (1912-1916). Este estudo considera que a reunião do núcleo inicial do eixo de Taquaruçu até Caraguatá era formado por um grupo sertanejo criador do projeto das cidades santas, seguidores dos monges, mas não era uma região impactada com processos sérios de concentração fundiária. A questão agrária era mais pronunciada nas regiões de expansão do movimento, fora do núcleo inicial. Fica destacada a diversidade dos perfis sociais e dos conflitos locais na expansão do movimento para além de seu núcleo original.

Published: December 2023

Linden honey represents a unique honey variety valued for its nutritional benefits, distinctive taste and aroma. Phenols, polyphenols, flavonoids, ascorbic acid and phenolic acids in honey have antioxidant activities. This study aimed to investigate the effects of linden honey on the activities of antioxidant enzymes catalase (CAT) and glutathione peroxidase (GPx), as well as on the concentration of malondialdehyde (MDA) in individually housed animals. The investigated parameters were quantified using spectrophotometric method for determination of enzyme activities and MDA concentration in the blood. We found that treatment with linden honey in the socially isolated animals significantly increased the enzyme activities of CAT and GPx, and significantly decreased the concentration of MDA. The modulation of CAT and GPx activities in socially isolated animals treated with linden honey may be very important for understanding the role of honey in the capacity of antioxidant defense system to increase and maintain its stability in psychosocial stress conditions. Our results may be important in biomedical research for understanding the role of honey in the amelioration of oxidative stress.
Clinical effects associated with miniscrews used as orthodontic anchorage
Authors: Kokitsawat Sulainee , Manosudprasit Montien , Godfrey Keith , Chatchaiwiwattana Charunee
Published: December 2023

Aims

To measure the clinical effects associated with miniscrew anchorage used to retract the upper anterior teeth, specifically the positional changes associated with the miniscrews, the upper anterior teeth and the first upper molars.

Methods

This clinical trial included 13 patients. After orthodontic alignment, miniscrews were inserted in the maxillary zygomatic buttresses as anchorage for en masse retraction of the upper anterior teeth. Following premolar extractions, nickeltitanium closed coil springs, stretched between the miniscrews and upper archwire, were used for retraction. Three-dimensional changes in the upper anterior teeth, the upper first molars and the heads of the miniscrews were measured on study models taken before a 300 g force was applied and seven months later, or when retraction was completed if less than seven months.

Results

The mean duration of retraction was 5.23 months (SD: 1.74 months) with a range of three to seven months. The mean amount of anterior retraction was 3.82 ± 1.64 mm (Range: 0.77-7.07 mm). Average movements of the miniscrew heads on the right side were 0.44 mm buccally, 0.38 mm forward and 0.54 mm downward, and on the left side 0.06 mm buccally, 0.41 mm forward and 0.50 mm downward. During the study period the right and left upper first molars moved mesially 0.70 ± 0.46 mm (Range: 0.01-2.3 mm) and 0.76 ± 0.47 mm (Range: 0.1-2.61 mm) respectively, although no force was applied to them.

Conclusion

Miniscrews provide satisfactory anchorage for retraction of the upper anterior segment, but do not remain absolutely stationary under orthodontic loads. Because of coincidental mesial movement of the upper molars, there must be sufficient clearance mesial to the molars to avoid the molar roots contacting the miniscrews.
Risk factors and indications of orthodontic temporary anchorage devices: a literature review
Authors: Hoste Sofie , Vercruyssen Marjolein , Quirynen Marc , Willems Guy
Published: December 2023

Aims

The aims of this review are twofold, firstly, to give an overview of the general and local risk factors when using temporary anchorage devices (TADs) and the prerequisites for placement and, secondly, to illustrate the orthodontic indications of various TADs.

Methods

The PubMed database was searched for original articles on: ‘orthodontics and miniscrews/mini-implants/ miniplates/temporary anchorage devices/titanium screws/skeletal anchorage’, ‘miniscrews/mini-implants/miniplates and risk factors/biomechanics/placement procedure’. Only articles published between 2001 and December 2007 were used. In addition, each article was hand searched for references that may have been missed by the PubMed search.

Results

General risk factors are factors concerning general health. Bone quality and oral hygiene are local risk factors. Aspects of the placement procedure discussed were: primary stability, loading protocols, pre-drilling diameter and whether or not to make an intra-oral incision. A selection of published case reports is given to illustrate some orthodontic indications of TADs.

Conclusions

Temporary anchorage devices have a place in modern orthodontics. Careful treatment planning involving radiographic examination is essential. Consultation with an oral surgeon is advisable if a soft tissue flap is required. Excellent patient compliance, particularly avoidance of inflammation around the implant, is an important consideration for successful use of TADs.
Are more nickel ions released from NiTi wires after sterilisation?
Authors: Poosti Maryam , Rad Hossein Pezeshki , Kianoush Kamyar , Hadizadeh Behzad
Published: December 2023

Background

Increased concentrations of nickel ions may be released into saliva from recycled NiTi archwires.

Aim

To compare the nickel ion concentrations released from recycled NiTi wires after sterilisation by either dry heat or steam autoclave.

Methods

Eighty preformed NiTi wires were assigned to four equal groups. In Groups 1, 2 and 3 the archwires were used intra-orally for 4 weeks. The Group 4 archwires were not used. Group 1 archwires were sterilised by dry heat, the Group 2 archwires were sterilised by steam autoclave, the Group 3 archwires were not sterilised and the Group 4 archwires were as-received. A 2 cm length, cut from each archwire, was immersed in artificial saliva for 4 weeks and the nickel ion concentrations in the artificial saliva measured with an atomic absorption spectrophotometer.

Results

There were no significant differences in the nickel ion concentrations released into the artificial saliva by each group of archwires (p = 0.467).

Conclusion

Sterilisation of used NiTi wires by either dry heat and steam autoclave does not affect the concentrations of nickel ions released into artificial saliva.
An evaluation of maxillary and mandibular rotational responses with the Clark twin block appliance
Authors: Lau Eden Y. , Sampson Wayne J. , Townsend Grant C. , Hughes Toby
Published: December 2023

Aims

To evaluate the dentofacial changes and growth rotational responses of Angle Class II division 1 patients treated with the Clark twin block functional appliance.

Method

This retrospective study comprised 13 boys (8.77 ± 0.86 years) and 13 girls (8.75 ± 0.70 years) treated by one orthodontist with the Clark twin block appliance. Selection was not biased by outcome and sample size power estimates exceeded 90 per cent. Tracings made on the pretreatment (T1), post-treatment (T2) and observation (T3) radiographs were superimposed on anatomically stable landmarks and the dentofacial changes and growth rotational responses compared. The data were tested for normal distribution and sexual dimorphism. Pearson correlation analyses of the treatment and observation phases were performed.

Results

In light of the few sex differences and lack of any consistent trends, the data for the boys and girls were combined. Treatment reduced the overbite, overjet and achieved Class II correction through combinations of maxillary incisor uprighting (U1-SN: –5.3 ± 5.3°), lower incisor proclination (L1-MP: 6.6 ± 6.8°), facial height increase (AFH: 5.1 ± 4.6 mm), ramal lengthening (Co-Go: 3.3 ± 2.4 mm) and mandibular length increase (Co-Pog: 5.9 ± 4.6 mm). During the observation period, similar growth changes were recorded, but the overbite (2.9 ± 1.9 mm) and overjet (3.6 ± 2.0 mm) increased due to some reversal of the treatment-induced incisor angulation changes. Over the treatment period (T1 to T2), the angles between the cranial base and maxillary (maxillary rotation) and mandibular stable structures (mandibular internal rotation) reduced by –0.1 ± 1.2 degrees and –0.3 ± 2.5 degrees, respectively. The angles between mandibular stable structures and Go-Me (mandibular external rotation) and SN-GoMe (mandibular total rotation) increased by 0.6 ± 1.7 degrees and 0.9 ± 2.1 degrees, respectively. Between T2 and T3, maxillary rotation, mandibular internal rotation and total mandibular rotation reduced –1.4 ± 2.0 degrees, –2.4 ± 2.5 degrees and –0.7 ± 1.7 degrees, respectively. Mandibular external rotation increased –1.8 ± 2.0 degrees. Mandibular total and internal rotation angles were significantly (p < 0.5) reduced at T2, but there were no significant associations between the rotations and dentofacial parameters during or following treatment.

Conclusions

On average, the maxillary and mandibular internal rotations were near zero during treatment, but the small and individually variable changes were not clearly associated with the Class II correction.

Authors: da Motta Andrea Fonseca Jardim , de Souza Margareth Maria Gomes , Bolognese Ana Maria , Guerra Clarice Júlia , Mucha José Nelson
Published: December 2023

Background

Older subjects usually show less of their upper incisors and more of their lower incisors than younger subjects.

Objectives

To determine how much of the upper and lower central incisor crowns are visible in Brazilian subjects with their lips at rest.

Methods

The subjects were 240 white Brazilian subjects divided into four age groups: Group 1, 12 to 15 years of age; Group 2, 20 to 30 years of age; Group 3, 31 to 50 years of age and Group 4, 51 years of age and older. Each group contained 30 males and 30 females. The vertical display of the incisors was measured in millimetres from the midpoints of the incisal edges of the upper and lower central incisors to the borders of the upper and lower lips.

Results

In females, the mean upper central incisor display reduced from 4.45 mm in Group 1 to 1.32 mm in Group 4, and in males it reduced from 3.35 mm in Group 1 to 0.57 mm in Group 4. Less of the lower central incisor crowns were displayed in Group 1 females (Mean: 0.47 mm) than in Group 4 females (Mean: 2.22 mm), and in Group 1 males (Mean: 0.61 mm) than in Group 4 males (Mean: 3.05 mm). Brazilian women showed significantly more of their upper incisor crowns than Brazilian men in Groups 1, 2 and 4, whereas Brazilian men showed significantly more of their lower central incisors than Brazilian women in Group 4.

Conclusions

With the lips at rest, older Brazilians display less of their upper central incisors and more of their lower central incisors than young Brazilians. Women show more of their upper incisors than men, while men display more of their lower central incisors than women.
Does ozone water affect the bond strengths of orthodontic brackets?
Authors: Pithon Matheus Melo , dos Santos Rogerio Lacerda
Published: December 2023

Background

Ozone water can be used to eliminate micro-organisms from the water systems in dental offices.

Objectives

To determine if ozone water diminishes the bond strength of orthodontic adhesives.

Methods

One hundred and twenty bovine mandibular incisors were randomly divided into four equal groups. The teeth were cleaned with pumice and washed either with tap water (Groups 1 and 3) or with ozone water Groups (2 and 4) before bonding stainless steel orthodontics brackets to the teeth with either a composite resin (Groups 1 and 2; Transbond XT, 3M Unitek, Monrovia, CA, USA) or a resin-modified glass ionomer cement (Groups 3 and 4; Fuji Ortho LC, GC America Corporation, Tokyo, Japan). The manufacturers’ recommendations for bonding were followed. All samples were subjected to thermal cycling and the shear bond strengths were determined with a universal testing machine. The Adhesive Remnant Index (ARI) was used to score the amount of resin remaining on the teeth after debonding the brackets.

Results

There were no statistical differences in the shear bond strengths of the brackets debonded from enamel washed with either ozone water or tap water or between the groups bonded with the two adhesive resins (p = 0.595). The ARIs in Groups 2 and 3 were significantly different from the ARIs in Groups 3 and 4 (p = 0.030).

Conclusion

Ozone water did not alter the bond strength of brackets bonded with composite resins, but it did alter the sites of resin fracture when Fuji Ortho LC was used.

Authors: Dastjerdie Elahe Vahid , Zarnegar Houman , Behnaz Mohammad , Seifi Massoud
Published: December 2023

Aim

To determine the strength of attachment between plain stainless steel band material and glass ionomer cement.

Methods

Seventy-five extracted upper premolars, free of visible structural defects, were used. The teeth were divided randomly into three groups and embedded in acrylic resin blocks. A short length of plain, stainless steel band material with a welded stainless steel standard edgewise 0.022 inch bracket was adapted to the buccal surface of each tooth. The bracket-stainless steel pads were then cemented to the teeth with either Bandtite (Group 1), Granitec (Group 2) or Ariadent (Group 3) glass ionomer cement and stored in an incubator at 37 °C for 30 days. The shear bond strengths of the specimens were measured and compared.

Results

The mean shear bond strengths (SBS) were significantly different: Bandtite 0.7331 ± 0.056 Mpa; Granitec 0.3869 ± 0.047 Mpa; Ariadent 0.2931 ± 0.033 Mpa (ANOVA, p < 0.001). Tukey HSD post-hoc tests also showed significant differences between Bandtite and Granitec, Bandtite and Ariadent, and Granitec and Ariadent (p < 0.001). All specimens failed at the band-cement interface.

Conclusion

The highest and lowest SBS were related to Bandtite and Ariadent cements, respectively. All cements had bond strengths less than the range of bond strengths considered to be clinically acceptable for bonded orthodontic attachments. Mechanical factors are important for band retention.
Measuring Accessibility and Optimising Logistics of Marginal Land Grass Biomass in the Case of Northern Ostrobothnia, Finland
Authors: Ollila Katri , Kotavaara Ossi
Published: December 2023

Grass biomass originating from marginal agricultural land unsuitable for food production can be utilised in variety of bio-based productions. The key profitability constraints for such productions are regional availability and transport costs. The aim of this paper is to methodologically test open access agricultural field parcel data – enabled by the EU INSPIRE directive – integrated with the road network in measuring biomass accessibility and optimising collection and transport using geographic information system (GIS) technology in two Finnish case areas. The analytical framework applies closest facility and vehicle routing analyses for tractor and truck transport scenarios. The key finding is that the area of field parcels and the amount of biomass accumulating within an observed area are not the only important factors influencing transport efficiency: cost-effectiveness of collection routes can be equally high in regions with scarce and abundant biomass areas.

Published: December 2023

Sustainable bioeconomy is one of the concepts that makes it possible to achieve the European Green Deal. A similar understanding of the term bioeconomy gives the opportunity to simultaneously take proportionate actions leading to the implementation of the Sustainable Development Goals in EU countries. Parallel understanding of the concept of bioeconomy is crucial for achieving a common consensus on actions aimed at introducing optimal plans for the development of green technologies. Therefore, the goal of the paper was to compare knowledge and perception about the bioeconomy in different countries. Realization of the work's objective was possible thanks to the use of the C&RT classification tree method. It was shown that the level of knowledge of respondents working or studying at selected universities was similar, while their perception of the bioeconomy differed significantly.
The Challenges of Small, Medium and Micro Enterprises in Engineering: South Africa
Authors: Mtambo Xolani Gladman , Lubbe Sam , Ohei Kenneth N.
Published: December 2023

The small, medium and micro enterprise sector is an economic engine for many countries. Realizing the potential of small, medium, and micro enterprises, the government of the Republic of South Africa has put a burden on itself to create 90% of jobs through small, medium, and micro enterprises through the implementation of the 2030 National Development Plan. Despite these initiatives, the failure rate of these enterprises in South Africa is still high and continues to increase. This research aims to investigate the challenges of small, medium and micro enterprises that operate in the formal economy, with the focus narrowed down to small, medium and micro enterprises that provide engineering services to engineering-intensive firms in the public and private sectors in South Africa. The target is a sample of member companies of Consulting Engineers South Africa, as well as random engineering service firms that render similar services. In general, engineering services’ small, medium and micro enterprises mainly depend on owners’ limited capital, which limits growth initiatives. Moreover, the absence of adequate resources, business facilities and specialised equipment puts small, medium and micro enterprises at a competitive disadvantage and, therefore, causes stagnation. Government’s initiatives are not well publicised and, therefore, small, medium and micro enterprises are not well informed to capitalise on such initiatives.

Published: December 2023

The era of Covid-19 is a condition that illustrates the uncertainty of national and world economic conditions, which encourages individuals to be able to manage their economy and finances. Therefore, this research aims to explain whether mental accounting, loss aversion bias, as well as risk tolerance can affect investment decision-making in the Covid-19 situation from the point of view of behavioral finance theory. The results of research using SEM PLS analysis show that Mental Accounting, Loss Aversion Bias, as well as Risk Tolerance, have an effect on investment decision-making. Based on behavioral finance theory, the results of the study illustrate that in the Covid 19 pandemic situation, individuals will generally respond to information received as a basis for making decisions by paying attention to the level of risk and optimizing the rate of return from the investment made.

Authors: Ngwakwe Collins C. , Lewis Janine
Published: December 2023

This research examines the differential effect of research-writing teaching innovation on proposal and dissertation completion rates at the Turfloop Graduate School of Leadership (TGSL). The method combined a review with a longitudinal quantitative secondary data design. The data on proposal and dissertation completion rates were compared using a t-test statistics. Findings show that at an alpha level of 0.05, a significant difference (at P<0.05) exists in the proposal and dissertation completion rates between the pre-innovation teaching period and within the innovation teaching period – with improved completion rate occurring during the teaching innovation period. Results also depict a mean difference in research methodology pass marks (albeit insignificance). Based on the findings, the paper contributes by developing an agency-based inclusive framework for teaching dissertation research writing. This framework provides an agenda for further research on teacher and student agency, and hence inclusive teaching of academic writing.

Circulating Silence. The Reaction to Rachel Carson’s Book Silent Spring (1962) in Scandinavian Gardening Magazines
Authors: Nielsen May-Brith Ohman
Published: December 2023

This article examines the reception of Rachel Carson’s book Silent Spring in Scandinavian family gardening magazines. In Sweden, Norway and Denmark, family gardening associations were broad organisations with significant social impact. They were the most important arenas for transfer of scientific knowledge and values on gardening, linking plant protection experts, producers and sellers of gardening chemicals, horticultural advisors and the general public. Thus, these associations and their magazines influenced many social groups that had common interests in non-commercial gardening as part of their everyday life. In practice, these family gardening magazines were heavily dependent on the income from garden chemicals advertisements. Consequently, their editorial policies and plant protection technical advice were deeply rooted in the post-war ideals of chemical agriculture and horticulture. These ideals were pursued and applied everywhere—even into the tiniest allotment and family garden. Scandinavian countries and their gardening associations have many similarities and some differences between them. This makes them an interesting case for comparison. The gardening magazines of Sweden, Norway and Denmark show quite a few similarities in the way they first pretended to ignore Carson while spending much effort countering the possible effects of her message, and in the way they retrospectively engaged with her book. There are, however, quite interesting differences in the way the national garden associations, their magazine editors and the magazines’ pesticide experts handled the publicity generated by Silent Spring on the harmfulness of garden chemicals.
Interface Selection and Optimization of Weights using Artificial Neural Network in Heterogeneous Wireless Environment
Authors: Rani Monika , Ahuja Kiran
Published: December 2023

Given the variety of networks, interfaces, mediums, and other resources accessible in a wireless heterogeneous location today, mobile communication is in a healthy competitive environment. When clients or users have access to numerous interfaces at once, a problem occurs. Users therefore require a clever or intelligent system to connect them to the finest services based on their needs and choices. Interface management controls the interfaces that are accessible and links the user to the best. The intelligent usage of various radio accesses/interfaces is made possible in this research by interface management with artificial neural networks (ANNs). Various parameters of different networks are used to make the choice. In this paper, a back propagation neural network (BPNN) method for switching between 3G, WLAN, 4G, and 5G networks is suggested. By allocating appropriate weights, the various network properties are employed as selection parameters. Fuzzy Analytic Hierarchy Process (FAHP) is used to initialize the weights, and the BPNN is used to optimize them. In order to obtain the best value, the goal value and the original value are compared, and the difference between them is used as an adjusting value for the weights. The network is trained using backpropagation techniques. The comparison between the proposed algorithm and the current algorithm demonstrates the new method's flexibility and the network's optimal connectivity with a high rate of successful handovers.
Electrical performance estimation and comparative study of heterojunction strained and conventional gate all around nanosheet field effect transistors
Authors: Abbasnezhad Reza , Saghai Hassan Rasooli , Hosseini Reza , Sedghi Aliasghar , Vahedi Ali
Published: December 2023

In this paper, we propose a novel type of Gate All Around Nanosheet Field Effect Transistor (GAA NS FET) that incorporates source heterojunctions and strained channels and substrate. We compare its electrical characteristics with those of the Heterojunction Gate All Around Nanosheet Field Effect Transistor (Heterojunction GAA NS FET) and the Conventional Gate All Around Nanosheet Field Effect Transistor (Conventional GAA NS FET). We investigate the impact of electrostatic control on both DC and analog parameters such as gate capacitance (C
gg), transconductance g
m, and cut-off frequency (f
T) for all three device types. In our Proposed GAA NS FET, we employ Germanium for the source and substrate regions, Silicon/Germanium/Silicon (Si/Ge/Si) for the channel, and Silicon for the drain region. The introduction of strain into the nanosheet and the use of a heterojunction structure significantly enhance device performance. Before utilizing a model to analyze a semiconductor device, it is crucial to accurately determine and elaborate on the model parameters. In this case, we solve the Density Gradient (DG) equation self-consistently to obtain the electrostatic potential for a given electron Fermi-level distribution, use the Shockley-Read-Hall (SRH) equation to estimate carrier generation, account for bandgap narrowing in transport behavior, and consider auger recombination. Our general results indicate a notable improvement in drain current, transconductance, and unity-gain frequency by approximately 42%, 53%, and 31%, respectively. This enhancement results in superior RF performance for the Proposed GAA NS FET compared to both the heterojunction GAA NS FET and the conventional GAA NS FET.
Feedback strategies in distance education: a survey of university students
Authors: Pentucci Maila , Laici Chiara
Published: December 2023

Screen-mediated teaching at the university level has necessitated a redesign of learning environments across various dimensions, encompassing epistemological, relational, and pragmatic aspects. How can the Digital Learning Ecosystem nurture these dimensions? Does the ecosystem initiate a feedback loop between the teacher and the student, configured not only as an evaluative process but also as a reflective and adaptive one? The feedback loop holds a generative value; it triggers an internal process in the student, enabling them to construct knowledge about their ongoing activities and comprehend through their own evaluative acts. Students stand as the ultimate source of all feedback; they are the ones who ultimately generate it, and it is this process that catalyzes learning. Feedback strategies further promote alignment between the teacher and the student, fostering continuous redesign and co-design.

The paper aims to present a survey collecting students’ perceptions on the condition of separation between professors and students during distance learning and activation of the educational relationship and feedback through digital devices.
Occupational allergic contact dermatitis: a case report
Authors: Băicoianu-Nițescu Livia-Cristiana , Radu Andreea Maria , Ivan Andreea-Paula , Smărăndescu Raluca Andreea
Published: December 2023

Allergic contact dermatitis is an inflammatory cutaneous reaction which occurs after immunological sensitization to the contact substance and clinically manifests with pruritic, erythematous, indurated, scaly plaques or cutaneous xerosis, thickening and scaling in case of chronic exposure. It is a T-cell mediated type IV reaction (delayed hypersensitivity response) and there have been discovered over 4000 contact allergens. As 30 percent of all occupational diseases involve cutaneous manifestations, irritant and contact dermatitis making up over 90 percent of instances of occupational skin diseases, the occupational doctor plays a key role in diagnosis and management of such patients. Prevention is the key in the treatment of this condition, thus recognizing the workplace risk factors, reducing antigen sources and providing appropriate protective equipment should be of utmost importance. Next, we present the case of a 48-year-old woman, who works as a technician in an aluminum manufacturing plant and who developed pruritic eczematous lesions located on the upper limbs, in order to review the risk factors and consequences of work-environmental exposure to allergens.

The long journey of tuberculosis (TB) from exposure to latent or progressive TB infection, from primary stage to second stage of illness with or without infectious status, and then to chronic post-TB sequelae is very complex and still unclear, including a various spectrum of stages and manifestations. A case report of a 55 year-old woman with personal history of pleural effusion, in her youth, 2 previous episodes of COVID-19 infections, having no exposure to active smoking but occupational exposure to wood dust, hot steam, barbeque smoke, was admitted to Constanta Clinical Pneumology Hospital in October 2022 for hemoptysis and fatigue. Clinical and paraclinical investigations highlighted an acute evolutive episode of Pulmonary TB with metastatic bilateral nodular pattern, negative smears, positive cultures and positive QuantiFERON TB Gold in Tube (QFT-GIT). TB standard regimen of therapy was started, based on QFT-GIT positivity, and after it ended, chronic obstructive pulmonary disease was detected by spirometry and small airways dysfunction by impulse oscillometry. TB illness does not stop after directly observed therapy ends. So, systematical screening of pulmonary, bronchial or pleural sequelae should be performed and identified syndromes need to be treated, as well as reintegration in the job process by a careful monitoring.
Patterns in medical surveillance of workers exposed to lung carcinogens

Published: December 2023

One of the most common causes of lung cancer is exposure to occupational carcinogens. Free silica, diesel exhaust fumes, dyes, radon and with asbestos at the top of the list, differ by percentage according to the predominant professional activities in each country. The occupational health doctor is directly involved in the surveillance of the exposed worker, during work or post exposure, in the diagnosis and reporting of occupational cancers. Efficient screening followed by reporting and monitoring cases of occupational lung cancer and, last but not least, reintegration into professional activity are important steps in the medical surveillance of the worker exposed to occupational lung carcinogens. Standardised information collected at the level of occupational exposure monitoring systems, separated by carcinogen category and profession, may form the basis of control and prevention plans. Harmonising medical surveillance at European and global level can lead to a decrease in the incidence and mortality of work-related lung cancer.
Emergencies in occupational medicine: the experience of an on-site medical office
Authors: Pârvu Bogdan-Mihail
Published: December 2023

Objective
: Medical emergencies (ME) in the occupational medicine (OM) office represent an increasingly frequent challenge, because they may require treatment or an ambulance, involving monitoring the patient, halting scheduled activity. The objective of this retrospective observational study was to study ME in the on-site medical office of a local pharmaceutical company, with an emphasis on the differences between major and minor emergencies, and on the factors associated with a longer duration of consultations, in order to optimize management.

Methods
: ME in the on-site office of a local company, January - June 2023 (109 working days), were recorded. The presentations were divided into 2 groups (G): G1 - ME that required ambulance/hospitalization/immediate treatment (etiological and/or symptomatic) and G2 - ME without immediate intervention.

Results
: During the 109 working days analyzed, 173 consultations involved ME (12.5% of the total presentations), with a mean of 1.6 presentations/day, On the 62 days with ME, the average was 2.7 presentations/day. The presentations, with a mean age of 40.8 years and a female predominance (69.4%), were divided into 2 groups: G1 included 95 (54.9%) presentations with immediate intervention, G2 - 78 (45.1%). In G1, 8 (8.4%) presentations required ambulance to hospital, 39 (41.1%) received etiological treatment, and 76 (81.1%) symptomatic treatment. Presentations for infectious diseases in a pandemic context ranked first This emphasizes the role of the OM physician in assessing Covid-19 contacts/patients. An ME consultation lasted on average 16.2 minutes, with a maximum of 19.4 minutes (excluding Covid-19 rapid testing). The most frequent ME complaints/humors were of cardiovascular, neurological, digestive and musculoskeletal origin. The maximum duration was in cardiovascular disease, associated with each type of intervention (p<0.0001 in the 3 cases: ambulatory/symptomatic/etiological treatment).

Conclusion
: ME in the OM doctor’ activity are frequent, more so in middle-aged women, especially between 12:01-16:00. They add approximately 2-3 consultations daily, in addition to the scheduled ones (30-45 additional minutes). Most ME require medical intervention: treatment in the office/ambulance. Apart from the COVID-19 context, most ME were cardiovascular (most time-consuming), digestive, neurological, and musculoskeletal. The duration of emergency consultations, additional to appointments, could require dedicated intervals, in order not to overload the physician. A systematized analysis of ME, paralleled by a good feedback towards the employer, could favor an individualized approach and an optimized endowment of the office, allowing identification of undiagnosed chronic disease, which would enhance productivity.

Packaging industry’s raw material producers face continuous challenges of sustainable development. Besides raw material and energy consumption mitigation, essential functions of product protection must be maintained. Re-use and recycling of waste materials must be provided, which is required by the European Union directives as well. Multi-beverage carton recycling is even more difficult due to the use of various materials, due to their diverse properties and qualities. The introduced paper is part of a complex study, which aims to prove that utilizing dry-grinding technology and no additives, semi-finished products can be produced for the packaging industry.

The article presents a preliminary study of the correlation between films properties and flexographic print quality defined as the optical density of full tone. It is also an attempt to answer the question whether traditional plastic films can be replaced by biodegradable and compostable films as printing substrates and as materials for packaging. Four kinds of films were used in the experiments – two plastic films (PP and PET) and two biodegradable films (PLA and cellulose). The permeability to water vapour and oxygen, as well as the tensile strength and elongation at break of the material were investigated for all samples. The measurements of the contact angle with water, diiodomethane and printing ink were also conducted for these films, and their surface free energy was determined. All samples were printed on laboratory equipment by a flexographic technique using water-based inks and the optical density of copies was measured. It has been found that the print quality was determined by the type of film used. Furthermore, the correlation between optical density and wettability defined as the contact angle between film and water or printing ink turned out to be significant. Other important parameter is surface free energy, albeit to a little lesser extent. The barrier and mechanical properties of the material have an even weaker impact on optical density. In addition, it is possible to choose the biodegradable film with properties corresponding to conventional, commonly used films which enable high quality prints
Störungsspezifische Handlungsleitlinien in der Kinder- und Jugendlichenpsychotherapie

Published: December 2023

Therapeutische Leitlinien können multimodal einen Beitrag der personzentriert-experienziellen Psychotherapie in einer allgemeinen Psychotherapie darstellen. Der vorliegende Beitrag diskutiert die Herausforderung, die therapeutische Leitlinien für psychostrukturelle nicht symptomatologisch orientierte Verfahren darstellen. Symptomatologisches Geschehen wird in der Personzentrierten Psychotherapie als ein Ausdruck struktureller intra- und interpersoneller Konflikte gesehen. Symptome verweisen nicht linear auf Konfliktkonstellation, sie geben nur begrenzt Hinweise auf Störungsursachen und auf ursachenbezogene Behandlungsansätze. Leitlinien konfligieren in der Personzentrierten Psychotherapie mit dem ganzheitlich-interaktionellen Verständnis der Person und dem Prinzip der Selbststeuerung, können jedoch helfen, das Störungswissen in personzentriertem Sinne zu nutzen und das empathische Verständnis und somit das Behandlungsangebot für den Klienten zu verbessern.

Published: December 2023

Störungen des Sozialverhaltens zählen zu den häufigsten und zugleich besonders deutlich andere Menschen beeinträchtigenden Verhaltensauf fälligkeiten im Kindes- und Jugendalter. Auf der Grundlage einer personenzentrierten Haltung werden Überlegungen zur Diagnostik und Differentialdiagnostik, zum Störungsverständnis und zu fallspezifischer Therapieplanung entwickelt. Diese kombinieren die bedingungsfreie Wertschätzung der Person mit der Bereitschaft zur Konfrontation mit dem auf fälligen Verhalten. Die Handlungsleitlinien zur Gestaltung der therapeutischen Arbeit beziehen sich in je eigener Darstellung auf die Eingangs-, die mittlere und die Abschlussphase einer Psychotherapie. Es werden für jede Phase Empfehlungen zur Begegnungshaltung, zu den Handlungsstrategien und den Interventionsmethoden formuliert. Handlungsleitlinien für die Zusammenarbeit mit den Bezugspersonen schließen den Beitrag ab.
