Nouvelle interprétation du bâtiment méroïtique XLIII de Meinarti (Nubie soudanaise) : Quelques pistes de réflexion pour distinguer entrepôts, greniers et marchés
Authors: Choimet Gabrielle
Published: December 2024

Building XLIII at Meinarti was initially interpreted as a warehouse, before being eventually attributed to a market. However, the presence of a raised floor and pairs of interconnecting rooms could not be satisfactorily explained. Although its function as a public facility is not questioned, Building XLIII raises issues as to the exact nature of the activities performed within its walls. A closer examination of the archaeological data shows that its interpretation as a marketplace with underground storage spaces is not consistent with the size of the low vaulted cellars underneath each room. Our hypothesis is that the raised floor rather acts as insulation against rising damp, which is perfectly conceivable in the context of food storage (cereals, wine, other types of foodstuffs). Interestingly, the closest parallels to this unique type of crawl space are found in the Western Roman world.
Les monuments inachevés de l’époque romaine au Liban. Une approche analytique du phénomène
Authors: Kahwagi-Janho Hany
Published: December 2024

During the Roman era, Lebanon experienced significant economic and urban growth. Thus, the Lebanese territory was marked by the development of dozens of largescale architectural projects. This evolution took two main aspects: on the one hand, several already existing buildings underwent an ‘upgrade’ in order to conform them to the newly introduced ‘canonical’ Roman models. On the other hand, several new projects emerged both in coastal towns and in rural areas. However, many, if not most, of these monuments remained unfinished. These unfinished states vary between the cancellation of large parts of the original construction program and the incompleteness of decorative details such as the entablatures of several others. Thus, through this article, we will discuss several examples showing the various aspects and levels of incompleteness of these monuments as well as the potential hypotheses linked to this phenomenon which seems to have become widespread during this period.
Słownik biograficzny profesorów jezuickich seminariów nauczycielskich – prolegomena projektu pedeutologicznej biografii zbiorowej
Authors: Królikowska Anna
Published: December 2024

Słownik biograficzny profesorów jezuickich seminariów nauczycielskich prezentuje sylwetki profesorów pracujących w seminariach od czasów odrodzenia, poprzez polski barok do oświecenia – ich zainteresowania, przygotowanie naukowe, pracę i doświadczenie pedagogiczne, twórczość literacką, szczególnie w zakresie poetyki i retoryki, ale też na polu teatru szkolnego. Użytkownik tego słownika może poznać jednostkowe losy, kariery poszczególnych profesorów, a zatem biografie indywidualne.
Materiał zgromadzony w słowniku otwiera również możliwość stworzenia portretu zbiorowego społeczności profesorów jezuickich seminariów nauczycielskich. Każdy członek tej społeczności jest osobą posiadającą własne, indywidualne cechy, stanowi jednocześnie cząstkę zbiorowości ludzi, którzy ze względu na podobne doświadczenia dydaktyczne mają wiele cech wspólnych. Poznanie jednostkowych losów (słownik) pozwala zatem na poznanie cech właściwych dla całej grupy. W tym kontekście celem badań jest próba uchwycenia wspólnych i charakterystycznych cech zbiorowości profesorów seminariów nauczycielskich. Pozwoli to następnie na ukazanie jej w szerszym kontekście edukacyjnym.
Badania nad portretem zbiorowym profesorów jezuickich seminariów nauczycielskich wpisują się w nurt badań biograficznych, w wyniku których powstaje biografia zbiorowa, obejmująca zarazem indywidualny obraz człowieka, jak i odzwierciedlone w nim podstawowe cechy danej społeczności i społeczeństwa danego okresu historycznego. Artykuł przedstawia podstawowe elementy składowe projektu zbiorowej biografii.

Badania zrealizowano w strategii jakościowej, w optyce paradygmatu interpretatywnego. Ich celem było poznanie i opisanie znaczenia biograficznego uczenia się do konstruowania i realizowania roli nauczycielki wychowania przedszkolnego.
Przedmiotem badań uczyniono zatem uczenie się roli nauczycielki wychowania przedszkolnego z biografii własnej i Innych, natomiast problemem badawczym pytanie: Jakie znaczenie ma biograficzne uczenie się do konstruowania i realizowania roli nauczycielki wychowania przedszkolnego przez badane kobiety? W badaniach wykorzystano metodę studium przypadku, a techniką, jaką posłużono się w celu zebrania materiału badawczego, był wywiad narracyjny przeprowadzony z trzema nauczycielkami wychowania przedszkolnego.
Wyniki badań własnych ukazują indywidualny proces biograficznego uczenia się roli nauczycielki wychowania przedszkolnego, jaki wyłania się z narracji badanych kobiet. W podjętych badaniach własnych ustalono, że biografia własna, jak i biografie Innych stanowią istotny walor edukacyjny, a podejmowany nad nimi namysł pozwala na kształtowanie wielu cech i umiejętności, które narratorki wykorzystują, konstruując i realizując własną rolę nauczycieli wychowania przedszkolnego.
El Mecanismo RED como el paradigma de apoyo europeo a la creación de empleo en España.
Authors: Martínez Mateo Carlos José
Published: December 2024

La UE para sus estados miembros contribuye a la protección y reactivación
del empleo en momentos de crisis o reconversión económica mediante
fondos, y un ejemplo del destino de estos es el denominado “Mecanismo
RED” español, una medida que, sirviéndose de recursos de la Unión, fue
diseñada tras la convulsión provocada en el marco de relaciones laborales
por la pandemia provocada por la COVID-19. Dicho Mecanismo aporta como
novedad que las medidas implementables a través de este han trascendido
de situaciones empresariales concretas a lo general, fundamentándose en
una “situación más generalizada, en el ámbito de un sector productivo del
conjunto de la actividad económica”. A tenor de lo expresado y a pesar de
que la decisión para activar este mecanismo de ayuda ya esté atribuida en
exclusiva al Consejo de ministros, se hace necesaria también una participación
importante y directa de los agentes sociales y un mayor desarrollo legislativo.
Descarbonización y transición justa e inclusiva con las personas con discapacidad: una senda aún por explorar.
Authors: Rueda Monroy José Antonio
Published: December 2024

En el presente estudio se analiza la relación entre las políticas de
descarbonización y la inclusión laboral de las personas con discapacidad,
con especial énfasis en los posibles efectos de la misma sobre el colectivo. En
el marco de la “transición justa”, se examina la presencia de la discapacidad
en las normas generales tanto internacionales como internas, sin embardo
resultan insuficientes las medidas específicas destinadas a este colectivo
vulnerable, a pesar de las esas obligaciones asumidas por el Estado. Asimismo,
el artículo propone medidas concretas para que en la transición hacia una
economía descarbonizada no se deje atrás a las personas con discapacidad.
Se concluye que integrar plenamente a las personas con discapacidad en
la transición ecológica es tanto una obligación legal como una oportunidad
para construir una sociedad más equitativa y sostenible, en línea con los
Objetivos de Desarrollo Sostenible y los principios de la Convención sobre
los Derechos de las Personas con Discapacidad.
Hacia la transición justa y sostenible del empleo digitalizado. Algunas reflexiones sobre la formación profesional y el Plan Europeo de Acción de Educación Digital (2021-2027).
Authors: Aragüez Valenzuela Lucía
Published: December 2024

La educación es un derecho humano; por lo que, en consonancia con el pilar
europeo de derechos sociales, los Estados miembros y las empresas deben
adoptar medidas destinadas a un aprendizaje permanente que brinde a
la sociedad de oportunidades de acceso al empleo, desarrollo personal y
profesional, y lo conviertan en uno de los principios rectores esenciales de
las políticas de educación y formación.
En el presente trabajo se reflexionará sobre la importancia de una cualificación
completa ante los retos de la doble transición digital y ecológica del empleo,
con fundamento en una formación validada y certificada en habilidades
digitales, ecológicas y sostenibles. De entre los mismos, se reflexionará sobre
la importancia de vincular el aprendizaje en competencias con un permiso de
formación retribuido, donde se fomenten unos niveles básicos de formación
especialmente centrados en acabar con la brecha generacional y por razón
de género existente en la vida en sociedad.
Así las cosas, se propondrán algunas medidas y políticas internas que se
consideran necesarias para que las empresas, teniendo muy presente el Plan
Europeo de Acción de Educación Digital (2021-2027), sean especialmente
conscientes de las desigualdades existentes y los retos a nivel laboral que
ciertos colectivos –considerados más vulnerables– sufren ante un modelo
de trabajo cada vez más digitalizado y escasamente orientado hacia lo justo.

La Gran Dimisión: perspectivas jurídicas.
Authors: Rodríguez-Piñero Royo Miguel
Published: December 2024

La Gran Dimisión es un fenómeno propio de un momento y un lugar concretos, pero en otros países se están viviendo cosas parecidas, que pueden considerarse «pequeñas dimisiones». No es tanto un rechazo al trabajo como a ciertos
tipos de éste, los que el mercado de trabajo está generando en el siglo XXI, que no
son valorados por las personas que están llegando a éste. Hay una huida del mercado
de trabajo, un auténtico Trabexit. En este trabajo se define este fenómeno desde una
perspectiva legal, con especial atención a las consecuencias jurídicas de abandonar
un puesto de trabajo. A partir de ahí se reflexionará sobre la existencia de un «derecho a decidir» sobre el trabajo y su impacto en la propia vida. Finalmente, se prestará atención a algunos derechos de última generación que están apareciendo en nuestro
ordenamiento, que afectan a esta capacidad de decisión de las personas.
Régimen Jurídico de la Dimisión. Cuestiones Conflictivas.
Authors: Pedrosa González Juan
Published: December 2024

Se analiza la institución jurídica de la dimisión como causa de extinción del contrato de trabajo, por voluntad de la persona trabajadora, desde una perspectiva de análisis de algunos de las situaciones conflictivas o litigiosas que produce
su regulación en la práctica. A estos efectos, se diferencia entre la dimisión ordinaria
(art. 49 ET), y la dimisión causal o provocada, que requiere seguir un procedimiento
judicial y acreditar el incumplimiento grave por parte de la empresa de alguna de sus
obligaciones inherentes a la relación laboral, y conlleva indemnización de ser estimada judicialmente (art. 50 ET).
Las numerosas reclamaciones judiciales sobre los diversos aspectos de la dimisión
conducen a sostener que la regulación de ambos tipos de dimisiones requiere una renovación o reforma legal. No sólo porque su redacción permanece casi idéntica desde
el Estatuto de los Trabajadores de 1980, sino porque en el contexto actual del mercado de trabajo y el empleo, tales textos no dan respuesta a la nueva dimensión de
la dimisión, o extinción del contrato por voluntad de la persona trabajadora, ni al necesario equilibrio de los intereses de las partes del contrato laboral. Se plantea, además, la necesidad de reconocer legalmente la ejecutividad en la extinción por dimisión causal, y reconocimiento de indemnización por la pérdida del trabajo provocada por incumplimiento de obligaciones de la empresa, o lesión de derechos.
Las microcredenciales como acción formativa ¿válida? En la reestructuración empresarial.
Authors: Dormido Abril Julia
Published: December 2024

La formación tiene por objeto mejorar las competencias profesionales
de las personas trabajadoras, así como su empleabilidad, de manera que, a través de
aquella, se pueda garantizar el mantenimiento los trabajadores en el mercado laboral.
Por su parte, el Estatuto de los Trabajadores ha previsto que las empresas que inicien
un proceso de reestructuración tienen que programar una actividad formativa para
sus trabajadores. Ésta deberá ser negociada en determinados supuestos con la representación legal de los trabajadores. Si bien, la actividad formativa a la que se refieren
los diferentes preceptos de la norma laboral no se ha detallado, por lo que ésta podría consistir tanto en un curso breve, como pueden ser las microcredenciales, como en
otro de una mayor extensión.
Desde el año 2022, la Unión Europea está apostando por estas microformaciones, o lo que es lo mismo, por una fórmula de aprendizaje de corta duración, a través
de las cuales se puedan acreditar las competencias adquiridas por las personas trabajadores o estudiantes. De esta forma, a través de pequeños módulos se podría cursar un
itinerario formativo completo. Por ello, en el presente trabajo se valorará si las microcredenciales pueden considerarse una acción formativa válida para dar cumplimiento a la citada exigencia legal impuesta para los procesos de reestructuración empresarial.
Neutral Pivoting: Strong Bias Correction for Shared Information
Authors: Rilling Joseph
Published: December 2024

In the absence of historical data for use as forecasting inputs, decision makers often ask a panel of judges to predict the outcome of interest, leveraging the wisdom of the crowd Surowiecki [Surowiecki J (2005) The Wisdom of Crowds (Anchor, New York)]. Even if the crowd is large and skilled, shared information can bias the simple mean of judges’ estimates. Addressing the issue of bias, Palley and Soll [Palley AB, Soll JB (2019) Extracting the wisdom of crowds when information is shared. Management Sci. 65(5):2291–2309] introduces a novel approach called pivoting. Pivoting can take several forms, most notably the powerful and reliable minimal pivot. We build on the intuition of the minimal pivot and propose a more aggressive bias correction known as the neutral pivot. The neutral pivot achieves the largest bias correction of its class that both avoids the need to directly estimate crowd composition or skill and maintains a smaller expected squared error than the simple mean for all considered settings. Empirical assessments on real data sets confirm the effectiveness of the neutral pivot compared with current methods.

Jointly Modeling and Clustering Tensors in High Dimensions
Authors: Cai Biao , Zhang Jingfei , Sun Will Wei
Published: December 2024

Tackling High-Dimensional Tensor Clustering

In the paper “Jointly Modeling and Clustering Tensors in High Dimensions,” Cai, Zhang, and Sun address the challenge of jointly modeling and clustering tensors by introducing a high-dimensional tensor mixture model with heterogeneous covariances. The proposed mixture model exploits the intrinsic structures of tensor data. The authors develop a computationally efficient high-dimensional expectation conditional maximization (HECM) algorithm and show that the HECM iterates, with an appropriate initialization, converge geometrically to a neighborhood that is within statistical precision of the true parameter. The theoretical analysis is nontrivial because of the dual nonconvexity arising from both the expectation maximization-type estimation and the nonconvex objective function in the M step. They also study the convergence rate of the algorithm when the number of clusters is overspecified and when the signal-to-noise ratio diminishes with sample size. The efficacy of the proposed method is demonstrated through numerical experiments and a real-world medical data application.
An attempt to identify factors influencing the effectiveness of physical exercise in virtual reality conditions in the treatment of anxiety and depressive disorders – study design
Authors: Pudlo Robert , Kunert Łukasz , Pankiewicz Zbigniew , Szczegielniak Anna Rebeka
Published: December 2024

Introduction: Virtual reality (VR) has been shown to have beneficial effects in the treatment of depressive disorders, anxiety disorders, eating disorders, and addictions. This method is relatively safe and noninvasive, but its effectiveness is variable, and predictors of effectiveness have been investigated in a limited manner. We hypothesized that personality traits could impact VR effectiveness, and that cognitive impairments might relate to its therapeutic success.
Material and methods: The study involves a randomized sample of 40 patients diagnosed with anxiety and mood disorders (ICD-10 F3x and F4x) from a psychiatric rehabilitation daily unit. Over 12 weeks, they will participate in a therapeutic program that includes exercise sessions enhanced with virtual reality (VR) interventions lasting 10 to 12 minutes each. A control group of 40 patients will follow a standard therapeutic program without VR. During the screening phase, we will assess anxiety and depression severity using the HADS and STAI. We will also evaluate patients' physical fitness by using the 6MWT, personality traits by using the HEXACO-60 Personality Inventory, and cognitive functioning by the ACE III, MoCA, FAB and RAVL tests.
Results: The procedure's effectiveness will be measured using HADS and STAI assessments for anxiety and depression at weeks 6, 12, and 4 weeks after the program.
Conclusions: Defining the subpopulation of patients sensitive to the proposed therapeutic interventions and analyzing the factors influencing their treatment will allow offering therapy in virtual reality to those who will benefit the most from it.

Keywords: virtual reality, physical exercise, depression, anxiety disorder, HADS
Safety of pharmacotherapy with Selective Serotonin Reuptake Inhibitors in patients on the autism spectrum - Case report
Authors: Kister Klaudia , Makarewicz Agata , Dzikowski Michał , Drzał Ewelina , Wróbel-Knybel Paulina
Published: December 2024

Introduction: Depression is one of the most common mental disorders in the world, and treatment of this condition often includes the use of selective serotonin reuptake inhibitors (SSRI). Despite their widespread use and effectiveness, SSRI can cause adverse effects, especially in the pediatric and adolescent population, which requires close specialized supervision. A particularly vulnerable group are patients with autism spectrum disorders, where reactions to SSRI can be atypical and unpredictable.
Purpose: The aim of this study is to report an atypical response to sertraline treatment in a minor patient with a diagnosis of Asperger's syndrome, resulting in impulsive and aggressive behavior with legal consequences.
Case description: A 16-year-old patient with Asperger syndrome was treated with sertraline for depression and suicidal thoughts. Within three weeks of starting therapy, he developed severe symptoms of agitation, delusions and aggressive behavior that led to conflict with the law. The patient was referred for forensic psychiatric observation, where he was diagnosed with acute psychosis with symptoms of delusions of grandeur meeting the criteria for acute manic state F30.2. according to the ICD­10 classification.
Conclusions: This case illustrates the risks of using SSRI in autistic patients, indicating the need for further studies on the safety of pharmacotherapy with this group of drugs in this population. The authors suggest special caution and the need to monitor children and adolescents taking SSRIs and to consider hospital conditions for the treatment of at-risk patients.

Abstract. Munawir A, Mardiastuti A, Masy’ud B, Prawiradilaga DM. 2024. Rehabilitation criteria and indicators for the successful release of Javan hawk-eagle (Nisaetus bartelsi Stresemann, 1924). Biodiversitas 25: 3491-3499. The Javan hawk-eagle (Nisaetus bartelsi Stresemann, 1924) is an endangered bird of prey that is native to Java Island and is protected by law. In order to save the species, rehabilitation programs are crucial for increasing its population in the wild. The current research aimed to establish criteria and indicators for rehabilitating Javan hawk-eagles and improving their chances of a successful release. Data were collected from literature review, interviews, and field observation. Collected data were scored based on a Likert scale and weighted on selected criteria and indicators, then described qualitatively. The research resulted in the identification of 34 criteria and 152 indicators. There were several rehabilitation stages observed in this research: 1) acceptance stage with 10 criteria and 30 indicators; 2) isolation stage with as many as six criteria and 18 indicators; 3) treatment stage with as many as four criteria and 12 indicators; 4) pre-training stage with as many as five criteria and 15 indicators, 5) training stage with five criteria and 65 indicators, and 6) habituation stage with four criteria and 15 indicators. The testing of 12 Javan hawk-eagle individuals at the Javan Hawk-eagle Sanctuary Center (JHESC), along with the developed criteria and indicators, could be feasible for rehabilitation standards to release Javan hawk-eagles successfully. According to the decision tree, nine out of the 12 individuals went through four stages, one went through three stages, and two went through two stages. In summary, the criteria and indicators have increased potential numbers and accelerated the rehabilitation process for the success of Javan hawk-eagle release.

Abstract. Mahrus H, Idrus AA, Syukur A. 2024. Mitochondrial DNA of CO1 and 16S rRNA genes for diversity and phylogenetic analysis of sardine (Sardinella spp.) from the Lombok Straits, Indonesia. Biodiversitas 25: 3500-3509. Sardines in Indonesia consist of six species from around 21 species- world, having many similarities and difficulty distinguishing between one species and others caused the taxonomy of the Sardines species is still ambiguous affected the same names in two different species and the different names in one species because of morphological similarities. The most effective method for identifying animal species and subspecies is the molecular method using sequences of the cytochrome c oxidase subunit 1 (CO1) gene and the 16S rRNA gene. The study aims to determine the molecular characteristics, genetic diversity, and phylogenetic relationships of sardines in the Lombok Strait using a sequence of CO1 and 16S rRNA genes. The study has significant practical implications as it can potentially inform conservation efforts and fisheries management. The sardine samples were collected from the Lombok Strait by small-scale fishermen. The sampling method was random. It takes 55 individuals as a sample. Initially, the sardine samples were grouped based on morphological characteristics. Subsequently, DNA from the two genes of 20 sardine samples were separated and amplified using two pairs of primers. The DNA amplification yielded 671 bp for the CO1 gene and 625 bp for the 16S rRNA gene. The sequence data from the two genes were analyzed using Molecular Evolutionary Genetics Analysis Version 11 (MEGA 11). The CO1 gene sequence revealed that sardines from the Lombok Strait could be determined more accurately than the 16S rRNA. CO1 rRNA genes of 12 individuals indicated a close genetic relationship between sardines of Lombok Strait and Sardinella aurita Valenciennes 1847, and the 16S rRNA gene placed sardines from Lombok Strait as an out-group. It empirically demonstrates that the CO1 gene is more effective than the 16S rRNA gene in identifying and determining molecular characteristics, genetic diversity, and phylogenetic relationships of sardines in Lombok Strait.

Abstract. Soipijit S, Sopaladawan PN. 2024. Wing geometric morphometric analysis of dwarf honeybee (Apis florea) populations in Thailand. Biodiversitas 25: 3568-3575. The dwarf honeybee, Apis florea Fabricius, 1787, is native to Thailand and distributed throughout the country. It plays a vital role in agriculture and the environment as an excellent pollinator of crops and economic plants in Thailand. Deforestation and insecticide usage have decreased populations of A. florea. There is a need for more information about the diversity of this species in Thailand, particularly its morphological diversity. This study aimed to determine variation among A. florea populations in Thailand based on geometric morphometrics of right forewings. Samples of adult A. florea worker were collected from 81 colonies across Thailand. Forewing shape variation was examined based on 19 landmark coordinates. The results revealed that landmark number 15 had the highest variance, followed by landmark numbers 14 and 16 with the S2=0.00004646, 0.00004436, and 0.00004024, respectively. Principal component analysis (PCA) showed that A. florea populations were distributed as one group, consistent with discriminant and cluster analyses. In addition, multivariate analysis of variance (MANOVA, ?=0.05) was not significantly different among populations. In summary, A. florea in Thailand had less morphological diversity than Apis cerana Fabricius, 1793 and Apis mellifera Linnaeus, 1758. This exciting information provides valuable insight for conserving A. florea in Thailand.

Abstract. Sahrir PRM, Mustaffa MB, Izam NAM, Nasir DM, Hatta SKM, Abdullah NA. 2024. Diversity of Diptera in mixed-used agroforestry area of Tun Razak Agricultural Research Centre, Pahang, Malaysia. Biodiversitas 25: 3576-3584. The order Diptera, comprising flies, mosquitoes, midges, and gnats, plays a significant role in the agricultural ecosystem as pests and pollinators. With agricultural activities posing a threat to insect populations globally, there is a need for studies on the potential of managed agroecosystems as habitats for this order. This study provides preliminary information on Diptera diversity in a mixed-used agroforestry area at the Tun Razak Agricultural Research Centre (Pusat Penyelidikan Pertanian Tun Razak/PPPTR), Pahang, Malaysia. The diversity assessment was conducted using malaise traps in various areas within the PPPTR, including a small forest fragment, a rubber plantation, an oil palm plantation, and an orchard, over two weeks in February and March 2023 yielded promising results. A total of 1,077 individuals representing 17 families, 36 genera, and 82 morphospecies of Diptera were collected during the research. The most abundant family recorded was Dolichopodidae, with 429 individuals, followed by Phoridae (140 individuals) and Calliphoridae (130 individuals). Notably, rubber plantations exhibited the highest diversity of Diptera (H'=3.228), while forest fragments showed the lowest diversity (H'=2.745), as indicated by the Shannon-Wiener Diversity Index. These findings highlight the potential of managed agroforestry areas as crucial Diptera conservation habitats, instilling hope and optimism in the scientific community.

Published: December 2024

Objectives: In this study, we sought to develop and evaluate a mobile application for use with intra-oral photography and to assess its educational potential among dental hygiene students. Methods: The study included 29 dental hygiene students. Participants’ skills and self-efficacy were evaluated before and after using the application for intra-oral photography. Statistical analyses, including paired t-test and Friedman test, were performed to assess performance and self-efficacy changes. Results: Use of the application significantly improved the students’ photography skills (p<0.05), with the largest improvements found in the mandibular occlusal view (25.7%), right buccal view (14.7%), and left buccal view (14.6%). Self-efficacy also increased significantly (p<0.001), particularly in terms of the ability to perform accurate clinical intra-oral photography. User satisfaction was high, particularly regarding photo storage and management (4.88±0.21) and tutorials available (4.86±0.44). Conclusions: The mobile application developed here enhanced students’ intra-oral photography skills and self-efficacy. This application has good potential as a self-directed learning tool for dental hygiene education, helping students to improve their clinical proficiency.
Qualitative study on the experiences in home-visit oral health care intervention activities of dental hygienists
Authors: Moon Sang-Eun
Published: December 2024

Objectives: This study aimed to provide basic data for effective community home-visit oral healthcare interventions by analyzing the perspectives of dental hygienists with experience in home-visit oral healthcare. Methods: A survey was conducted among dental hygienists providing home-visit oral healthcare to vulnerable and elderly residents of Gwangju. In-depth interviews with 11 participants were conducted from August 5 to September 6, 2024, and the data were analyzed using Colaizzi’s phenomenological method. Results: A total of 150 semantic words and 13 subcategories were collected which were categorized into five central meanings such as ‘Environmental barrier and cognitive limit’, ‘Insufficient information and asymmetric relationship’, ‘Expansion of support and multidisciplinary cooperation is needed’, ‘Efforts for effective oral care’, and ‘Job achievement and place for opportunities’. In particular, a poor residential environment and lack of understanding of oral healthcare were barriers, while insufficient information and uncooperative behaviors hindered dental hygienists’ intervention activities. Conclusions: Effective home-visit oral healthcare requires improving information systems, ensuring safety, strengthening cooperation, and expanding the roles and competencies of dental hygienists.

Authors: Sim Seon-Ju
Published: December 2024

Objectives: Sustainable management and social responsibility should be emphasized. This study investigated awareness of and attitudes toward ESG (Environmental, Social, Governance) management among dental hygiene students. Methods: Written consent was obtained from 114 volunteers who expressed their willingness to participate in the study. The survey items comprised 14 questions related to ESG. The awareness of and attitudes toward ESG management were analyzed by frequency and percentage, and the correlation between the awareness of and attitudes toward ESG was analyzed using Pearson’s correlation analysis. Results: The awareness rate of ESG management was 10.5%, and the main paths of ESG awareness were school classes (25.4%) and newspapers and news (21.1%). Correlations between the implementation of environmental, social, and governance factors were significant (p<0.05). Eight-six percent of students were willing to consider ESG issues when purchasing products, and 80.7% responded positively to their willingness to consider ESG issues when applying for a job. Conclusions: This study analyzed the awareness of and attitudes toward ESG and confirmed the need for ESG management education for dental hygiene students. In the future, we plan to use this as a basis for developing curricular and extracurricular programs to improve the awareness of and positive attitudes toward ESG management among dental hygiene students.
Advances in high-energy ns-pulse laser beam delivery through optical fibers
Authors: Tabakaev Dmitry , Nicoly Menezes de Oliveira Barbara , Noskov Roman E. , Kroupa Gerhard
Published: December 2024

We demonstrated that multimode optical fibers with a large cladding-to-core ratio achieve nearly 100% energy coupling efficiency and exhibit a high energy throughput of 16 mJ at a laser pulse width of 2 ns and a wavelength of 1064 nm, even when bent to a radius of 0.15 m. In addition, we explore the application of these fibers for spatial beam division in distributed rocket engine ignition systems. The primary limiting factors are analyzed, supported by simulations of pulse intensity propagation and distribution along the fiber and the experiment. We also discuss the formation of hot spots within the fiber as a function of both the fiber and input beam parameters.

Published: December 2024

Subwavelength plasmonic metasurfaces combined with multiple quantum wells (MQWs) heterostructures have recently demonstrated highly efficient nonlinear wave generation under low power input intensities. They can pave the way for developing highly efficient, compact, tunable and room temperature terahertz (THz) wave sources through the mixing and down-conversion of optical incident pumps. In this paper, we study and analyze the electrically controllable THz radiation of a nonlinear metasurface loaded with MQW through difference frequency generation (DFG) process. An analytical formulation procedure based on the effective nonlinear susceptibility model and free-space Green’s function is proposed for derivation of generated THz wave radiation pattern. Also, we demonstrate phase and amplitude variation of intrinsic second-order nonlinear susceptibility coefficient of MQW by applying different bias voltages. Far-field directivity pattern of DFG radiation from the linear array configuration of plasmonic nonlinear metacells is obtained at 5.5 THz through the proposed analytical method and is verified by full-wave analysis. Using the proposed electrical tunability of MQW nonlinear susceptibility, THz beam steering of the nonlinear metasurface is demonstrated which is rotated from -20 to 20 degree through different bias voltages. Our work proposes an effective tool for rapid and accurate design and analysis of highly efficient THz electrically tunable MQW nonlinear metasurfaces for future applications in THz wireless communications, spectroscopy and quantum imaging.

We theoretically study high-order harmonic generation (HHG) involving an extreme ultraviolet (XUV) pulse and an intense infrared driving field, where the electron is ionized by absorbing a single XUV photon. Using a developed classical-trajectory model that includes Coulomb effects and the improved initial conditions, it is demonstrated that the resulting harmonic emission times match well with those obtained by applying the Gabor transform to data from numerical solutions of time-dependent Schrödinger equations for helium and hydrogen atoms. This confirms a classical HHG scheme under single-photon ionization: The electron, ionized by absorbing one XUV photon, oscillates in the infrared field and may recollide with the parent ion, emitting high-frequency radiation. Therefore, the classical model can determine the ionization and recombination times of the electron in single-photon-ionization HHG. Our work shows great promise for resolving electron dynamics using high-order harmonic spectroscopy under single-photon ionization.

Published: December 2024

For indirect time-of-flight (iToF) cameras, we proposed a modeling approach focused on addressing random error. Our model characterizes random error comprehensively by detailing the propagation of error introduced by signal light, ambient light, and dark noise through phase calculation and system correction processes. This framework leverages correlations between incident light and tap responses to quantify noise impacts accurately. We then experimentally validated the theoretical model, confirming its predictive accuracy. Additionally, from a waveform design perspective, we recommend selecting an optimal duty cycle for the light waveform based on the relative intensities of ambient and signal light to effectively reduce random error.

To facilitate the development of compact multi-wavelengths lasers, we reported the experimental demonstration of dual seed sources master oscillator power amplifier (MOPA) QCLs. The devices were based on a sandwich configuration consisting of dual seed sources and a central power amplifier. Emission spectrum of devices was modulated by switching seed sources. By utilizing this design, two room temperature continuous-wave output power of 46 mW and 30 mW were obtained at modes 7.35 µm and 7.38 µm, respectively. The problem of power difference at the dual wavelengths have been improved. The two target modes were fine-tuning through current with tuning coefficients -0.0131 cm-1mA-1 and -0.0122 cm-1mA-1, respectively. The reported compact quantum cascade lasers with dual seed sources and fine-tuning characteristics are significant for developing miniaturized and on-chip sensing systems with multi-gas accurate detection.
Centroid shifts of spatiotemporal vortex pulses reflected and refracted on graphene
Authors: Cao Zhenzhou , Qiu Xuejun , Hou Jin , Yang Chunyong
Published: December 2024

The Goos-Hänchen and Imbert-Fedorov shifts are significant wave phenomena, yet the underlying mechanism governing the spatiotemporal vortex pulses reflected and refracted on graphene remains opaque. In this study, we analytically derive the expressions for the centroid shifts of spatiotemporal vortex pulses by applying the Fresnel-Snell formulas to each plane wave in the incident spatiotemporal vortex pulse spectrum. We demonstrate that the longitudinal shifts are correlated with the angular shifts, and thus, both are subject to resonant enhancement in the vicinity of the Brewster angle. It is possible to tune the resonant enhancement of the shifts by modifying the Fermi energy of graphene. An increase in the vortex topological charge l results in an enhancement of both the angular and longitudinal shifts while the transverse shifts are reduced. The shifts of the intensity distribution, in accordance with the Goos-Hänchen and Imbert-Fedorov shifts, facilitate experimental measurements. The high frequency in the terahertz region will diminish the resonant enhancement of the spatial shifts of the reflected wavepackets. The analysis presented here can be extended with minimal effort to spatiotemporal vortex pulses reflected and refracted on other two-dimensional atomic crystals.

We provide the first direct experimental evidence for the reorientation of liquid crystals by polarized radiation from a conventional, low power, oscillator-based terahertz time-domain spectrometer. Using a terahertz pump - optical probe setup, we observed that the reorientation occurs locally through the resonant amplification of the terahertz field in a specially designed planar metamaterial, adjacent to the liquid crystal layer, and increases with increasing incident terahertz intensity. Our work thus demonstrates that it is possible to induce strong optical nonlinearity in liquid crystals in the terahertz part of the spectrum, paving the way toward the development of new all-optical active terahertz devices as well as electric field sensors for localized resonant systems.

The technique of spectral polarization imaging (SPI) is a potent detection tool in various fields due to its ability to capture multi-dimensional information. However, existing SPI systems usually face challenges associated with architectural complexity and computational requirements, rendering them unsuitable for handheld, on-board, and real-time applications. Consequently, a compact single-shot multispectral polarization imager (CSMPI) is proposed, which employs a combined spectral-polarization encoding strategy to address the aforementioned issues. It incorporates a coded aperture for encoding multiple spectral channels together with linear polarization into a single measurement, enabling the simultaneous detection of up to nine light components with just one exposure. The resulting prototype consists solely of a color polarization detector and an imaging lens inserted with the small and easily fabricable coded aperture, which features compact dimensions of Φ5.5 cm × 21.5 cm and a light weight of approximately 670 g. This is particularly advantageous for application areas that require system miniaturization and rapid multi-dimensional detection.

People with disabilities (PWDs) due to neglected tropical diseases (NTDs) or other causes experience restrictions on social participation (RSPs). This study aimed to investigate the magnitude of these restrictions and associated factors in NTD-endemic communities in Benin and Côte d’Ivoire. This cross-sectional quantitative and qualitative study was conducted from 2021 to 2022 among 841 people with disabilities (PWDs) and 90 community members and stakeholders. Questionnaires and interview guides were used for data collection. The World Health Organization P-scale score adapted to the local context, was used to assess RSPs. Univariate and multivariate analyses were performed to identify associated factors. Qualitative data were processed using triangulation or data comparison, categorized, cross-referenced, and synthesized by theme, hypothesis and indicator. Of the 841 PWDs, 65.9% had experienced RSPs. The median age (Q1; Q3) was 38 (22; 52) years, and the M/F ratio was 1.45. Of the respondents, 89.2% had a monthly income between 0 and 50,000 FCFA (76 euros); 43.7% were married, and 64.4% were uneducated. Only 98 (11.7%) were disabled due to NTDs. Factors (OR [95%IC], p-value) associated with RSPs were age (30 to 44 years (1.66 [1.06–2.59], p = 0.026), 45 to 59 years (2.26 [1.43–3.58], p = 0.001), and 60 to 74 years (2.35 [1.29–4.27], p = 0.005); Secondary/University level of education ((0.42 [0.28–0.65], p = 0.000); occupation (shopkeeper/housekeeper (0.40 [0.17–0.91]), p = 0.029), farmer (0.21 [0.11–0.40], p = 0.000), and other professions (0.44 [0.20–0.96], p = 0.038)); and income-generating activities (IGAs) (1.53 [1.06–2.22], p = 0.023). Our results demonstrate that the magnitude of RSPs among PWDs is high. The associated factors were age, education level, occupation, and IGAs.
