In Europe, allergen products from different manufacturers can be labeled using the same unit with yet different definitions of that unit, which may cause confusion, as is the case for the index of reactivity (IR). In this context, house dust mite (HDM) Staloral 300 IR/mL, from Stallergenes Greer, and HDM Osiris 300 IR/mL, from ALK-Abelló, were characterized in vitro. Qualitatively, namely in terms of protein and allergen profiles, the two products were similar. Quantitatively, and despite the same 300 IR/mL labeling, the two products were shown to have different biological potencies, with HDM Staloral 300 IR/mL displaying a 2.4 times higher total allergenic activity (TAA) than HDM Osiris 300 IR/mL. This higher biological potency of HDM Staloral 300 IR/mL was paralleled by higher allergen and protein contents, namely 1.5 times more Der p 1 and Der f 1, 3.0 times more group 2 allergens, 2.7 times more Der p 23, and 1.8 times more protein. In contrast, HDM Staloral 300 IR/mL was shown to contain far fewer culture medium-derived proteins than HDM Osiris 300 IR/mL.

Published: August 2023

Introduction: Depression is a condition that can cause elderly people to experience mental or emotional disorders due to stress and loneliness. Stress is something that can disturb the elderly caused by anxiety and loneliness due to changes in roles in the family or in their lives. The purpose of this study was to determine the relationship between stress and loneliness with depression in elderly people in Banjar Kawan, Tampaksiring, Bali.

Methods: This study used a cross-sectional design with 68 elderlies recruited as respondents based on inclusion criteria by using purposive sampling techniques. The instruments used included the Perceived Stress Scale (PSS-10), UCLA Loneliness Scale Version 3, and Geriatric Depression Scale (GDS). The results of this study showed that most of the respondents aged 64 years, female, last education was elementary school, marital status was married with an income of < IDR 500,000.

Results: The correlation results showed a significantly weak positive correlation between stress and depression (r = 0.284, p = 0.019) and loneliness with depression (r = 0.254, p = 0.037). The results of multiple linear regression showed that stress (β = 0.266) has the most effect on the occurrence of depression compared to loneliness (β = 0.039) so the higher the stress felt, the higher the symptoms of depression in the elderly.

Conclusion: It is hoped that the elderly could improve their health by actively participating in many activities in order to prevent the symptoms of depression from getting worse.

Why we need to abandon fixed cutoffs for goodness-of-fit indices: An extensive simulation and possible solutions
Authors: Groskurth Katharina , Bluemke Matthias , Lechner Clemens M.
Published: August 2023

To evaluate model fit in confirmatory factor analysis, researchers compare goodness-of-fit indices (GOFs) against fixed cutoff values (e.g., CFI > .950) derived from simulation studies. Methodologists have cautioned that cutoffs for GOFs are only valid for settings similar to the simulation scenarios from which cutoffs originated. Despite these warnings, fixed cutoffs for popular GOFs (i.e., χ2, χ2/df, CFI, RMSEA, SRMR) continue to be widely used in applied research. We (1) argue that the practice of using fixed cutoffs needs to be abandoned and (2) review time-honored and emerging alternatives to fixed cutoffs. We first present the most in-depth simulation study to date on the sensitivity of GOFs to model misspecification (i.e., misspecified factor dimensionality and unmodeled cross-loadings) and their susceptibility to further data and analysis characteristics (i.e., estimator, number of indicators, number and distribution of response options, loading magnitude, sample size, and factor correlation). We included all characteristics identified as influential in previous studies. Our simulation enabled us to replicate well-known influences on GOFs and establish hitherto unknown or underappreciated ones. In particular, the magnitude of the factor correlation turned out to moderate the effects of several characteristics on GOFs. Second, to address these problems, we discuss several strategies for assessing model fit that take the dependency of GOFs on the modeling context into account. We highlight tailored (or “dynamic”) cutoffs as a way forward. We provide convenient tables with scenario-specific cutoffs as well as regression formulae to predict cutoffs tailored to the empirical setting of interest.

Authors:   The Korean Data Analysis Society, Lee Jin-Kyung , Ji Jae-Hoon
Published: August 2023

This study was conducted to provide implications for the improvement of nurses' job performance by examining the moderated mediating effect of perceived organizational support on the effect of nurses' work-life balance on job engagement and job performance. For this purpose, data were collected through a self-completion survey using a structured questionnaire with a convenience sample of nurses working in hospital-level or higher medical institutions in Busan and Gyeongnam. The collected data were analyzed using SPSS 27.0 and Process Macro 3.5. The factors that directly affect job performance, the final outcome variable, were in order of job engagement and work-life balance. It was found that the higher the level of job commitment and the higher the level of work-life balance, the better the job performance. On the other hand, work-life balance had a positive effect on job commitment, and work-life balance had an indirect effect on job performance through job commitment. Therefore, keeping in mind that the job performance of nurses, who are the core workforce of medical organizations, is directly related to the performance of the organization, it is necessary to improve their job engagement, and as part of this, it is necessary to build an organizational culture that emphasizes work-life balance.

Published: August 2023

This study aims to analyze the extent to which the implementation of the child-friendly district program is carried out in accordance with the statements in regional regulations, especially in Gorontalo Regency. The research method used is qualitative descriptive. Data sources are derived from primary and secondary data. Data collection techniques are obtained through observation, interviews, and documentation. Protection of children is an obligation of parents without discrimination because children need to live better wherever they are and must be guaranteed by all families and social environments, especially their parents. Children are vulnerable to violence, both from their age and from adult disorders. Violence against children, both women and men can occur in various environments, both in families, schools, and outside the home. Therefore, attention to child safety must be a priority carried out by parents, families and also the government, where it has been regulated or has official regulations in the form of law number 35 of 2014 so that no one can avoid criminal threats if there is violence against a child, it must be punished in accordance with applicable regulations. The results showed that the implementation of the Child decent District program policy in Gorontalo Regency has not been optimal due to low socialization carried out by the local government, lack of coordination between related agencies, and supervision of officers by agencies has not been effective, and efficient due to the lack of officers (HR), as well as inadequate facilities and infrastructure.

Authors: Mozin Sri Yulianty , Nggilu Rukiah
Published: August 2023

This research is to be directed to analyze the development of higher education transformation strategy models through strengthening institutional capacity. The method used is qualitative through in-depth interviews and documentation studies. The results showed that there are several factors that hinder the performance of universities, such as limited human resources and infrastructure. This condition demands organizational change in order to be able to adapt to fast and complex organizational dynamics. In the context of higher education governance, there is an urgent need to transform governance according to the main tasks and functions through strengthening institutional capacity. From this study, researchers recommend that the transformation of governance strategies and strengthening of the role of universities through strengthening institutional capacity need to be implemented comprehensively. It aims to build optimal organizational capacity by strengthening eight key aspects, namely: Strategic leadership; Organizational structure; Human resources; Financial management; Infrastructure; Management of programs and services; Process management; Inter-organizational relations; and Spiritual management. Through this approach, universities are expected to reflect a strong and strategic capacity, which in turn will assist the institution in achieving the vision and goals set in the Gorontalo State University strategic plan. By adopting this strategy, universities can be better prepared for future challenges and opportunities in the ever-changing world of higher education.

Integration of Environmental Ethics Education in the Classroom: A of Related Literature
Authors: OLAWUMI Kayode , MAVUSO Mzuyanda Percival
Published: August 2023

Due to the catastrophic impact of global warming and various environmental challenges, ecological issues are a topic of discussion in every country in the globe. Researchers believed that solutions to environmental problems lie in the integration of environmental ethics education in schools to create awareness of moral values and attitudes of humans toward the environment. However, there seem to be inadequate efforts to integrate environmental ethics education into the school curriculum. This study, therefore, argues for the examined literature to find out how school teachers integrate environmental ethics education in lessons. The study adopted the qualitative systematic literature review method, and twenty-six peer-review articles were selected from the EBSCO, Scopus, and Google Scholar databases. The twenty-six selected peer-review articles were analyzed to determine the level of integration of environmental ethics education in South African classrooms. The study revealed that the internalization of environmental ethics education as a moral foundation may make humans aware of their interaction with the environment. According to literature, awareness of improved environmental ethics education assist human to behave and act ethically towards nature thereby contributing to the reduction in environmental damage and improving environmental conservation and management. The study, therefore, suggests the organization of environmental ethical awareness in-service training programs by the Department of Basic Education for teachers which will expose them and their learners to environmental ethics, disciplined behavior, and positive attitude towards their environment.
Slowly Rotating Accretion Flow Around Supermassive Black Holes in Elliptical Galaxies: Case With Outflow
Authors: Ranjbar Razieh , Abbassi Shahram
Published: August 2023

Observational evidence and many numerical simulations show the existence of winds (i.e., uncollimated outflows) in the accretion systems of elliptical galaxy centers. One of the primary aims of this study is to investigate the solutions of slowly rotating accretion flows around supermassive black holes with outflows. This paper presents two distinct physical regions, supersonic and subsonic, which extend from the outer boundary to the black hole. In our numerical solution, the outer boundary is chosen beyond the Bondi radius. Due to strong gravity, we ignore outflow (i.e., s = 0) in the inner region (within ∼10r

s
). The radial velocity of the flow at the outer region is significantly increased due to the presence of the outflow. Compared to previous works, the accretion mode, namely, the slowly rotating case, that corresponds to low accretion rates that have general wind output is carefully described, and the effect of the galaxy potential and feedback by the wind in this mode are taken into account. As the power-law form of the mass accretion rate is mathematically compatible with our equations, we consider a radius-dependent mass accretion rate (

), where s is a free parameter and shows the intensity of outflow. There is an unknown mechanism for removing the mass, angular momentum, and energy by outflows in this study. The effects of the outflow appear well on the outer edge of the flow.
Predicting the Effect of Surface Properties on Enceladus for Landing
Authors: Harmon John M. , Cable Morgan L. , Moreland Scott J. , Andrade José E.
Published: August 2023

The prospect of landing on the surface of Enceladus comes with the question of whether the surface conditions permit selection and certification of one or more safe landing sites in an area of high science value. On Enceladus, the search for biosignatures in plume materials is a high science value objective that correlates with proximity to the south polar terrain, where the plume deposition rate is highest; however, such areas may be unsafe if unsintered particles make the landing site unstable. To investigate this, the surface of Enceladus was modeled using the level set discrete element method. This method models the kinetics and kinematics of large groups of individual ice particles both in contact and sintered together. Using the model, a rigid footpad was initialized at a 1 m s−1 descent just above the ice surface under Enceladus gravity. Parameters studied were the sintering amount, particle size distribution, footpad geometry, and surface slope. The model predicted that some sintering is required for the surface to support a lander; however, too much sintering can cause a lander to bounce. For tests on sloped surfaces, landing could be possible on slopes as steep as 20° for certain conditions, but it is safest to land in areas with a slope angle of 15° or less. While slope angle and sintering level were much more important than footpad geometry, the hemisphere footpad had the best performance (lowest slipping) in most cases compared to the cone or disk.
Name IDs and Name Matching for Catalogue of Life: Existing Services and Prospects
Authors: Bánki Olaf , Döring Markus , Jeppesen Thomas
Published: August 2023

ChecklistBank, developed by Catalogue of Life (COL) and the Global Biodiversity Information Facility (GBIF), is a publishing platform and open data repository focused on taxonomic and nomenclatural data sets (checklists). It contains close to 50K datasets, mostly originating from digitised peer reviewed scientific articles mediated by Plazi, amongst others. The COL Checklist (Bánki et al. 2023) is assembled out of a selection of the data sources in ChecklistBank. The Catalogue of Life Checklist is issued with name usage identifiers, as well as a digital object identifier for the Checklist version (with an associated dataset key). The more than 160 data sources that make up the COL Checklist are also issued with digital object identifiers as well as a data set key. The combination of a name usage identifier and the data set key allows for the tracking of names between the various COL Checklist versions. ChecklistBank is built in an open API. It supports data sharing through various exchange formats of the Darwin Core (Darwin Core Task Group 2009) data standard (e.g., Darwin Core-Archives (GBIF 2021) and ColDP), and provides several download and name matching options.

The Transforming European Taxonomy through Training, Research, and Innovations (TETTRIs) European Union funded project will contribute to a couple of improvements to ChecklistBank. In the context of the TETTRIs project, a new name usage (i.e., taxon or synonym) matching service against any dataset in ChecklistBank, not just the COL Checklist, was developed. A single name matching service takes query parameters for a single name and optionally its classification. The service allows for bulk matching of names against the ChecklistBank API. This contains the option of matching a classification in a CSV file. The bulk matching allows all names of an entire or a subtree of an existing ChecklistBank dataset to act as the source for names instead of the input matching a CSV file. The bulk matching services are asynchronous and notify a user by email when the results are ready to be downloaded in a CSV file.

Published: August 2023

ChecklistBank, co-developed by Catalogue of Life (COL) and the Global Biodiversity Information Facility (GBIF), provides a suite of functionalities for building taxonomic data solutions. In addition to serving as a publishing platform and open data repository for taxonomic and nomenclatural data, ChecklistBank includes tools for managing the assembly of new species lists from other datasets published to the platform. The ChecklistBank API provides access to all data sources, including the COL Checklist, all mediated through ChecklistBank. It also allows for (bulk) matching of names, and provides an overview of the name usage identifiers used by COL and the identifiers for the same taxon originating from other data sources.

The ChecklistBank infrastructure is still in development, but is starting to allow for various kinds of usages and services, including quality assurance and quality control. Examples will be presented of possible functionalities and services that could be added to ChecklistBank in future, including:

An option to push a ChecklistBank dataset to Github and then automate reimport from the same source (with appropriate validation). A Github representation, based upon the Catalogue of Life Data Package (ColDP) data model, could serve as a general resource against which developers can build new lightweight editing or batch update tools, including merge tools to bring in new names from ChecklistBank datasets, with Github providing versioning support and triggers for synchronisation with Github

An option to establish similar bidirectional editing models with other environments such as TaxonWorks or Aphia,

Notifications for checklist curators when previously unseen names and combinations for their group appear in new or updated ChecklistBank datasets

Enhancements to the data model and user interface to support better quality/completeness indicators (traffic lights).

The Catalogue of Life (COL) Checklist 2023 (Bánki et al. 2023) includes over 2.1 million accepted species underpinned by a large international community of more than 500 expert taxonomists. The 164 supporting sources are available through ChecklistBank, a publishing platform and open data respository with a focus on taxonomic and nomenclatural data sources. It also includes all the tools and processes that are needed to assemble the COL Checklist. ChecklistBank is jointly developed by Catalogue of Life and the Global Biodiversity Information Facility (GBIF). The results presented here build on efforts carried out in the European Union-funded project Biodiversity Community Integrated Knowledge Library (BiCKL).

Despite all the global efforts over the past 27 years, there still remain significant gaps in the COL Checklist: incompleteness, outdated data in several taxonomic groups, lack of synonyms and a considerable time lag in being up-to-date with continuously published literature. However, there are not enough experts to check and update it as fast as new information is published e.g., descriptions of new species, covering lesser-known taxonomic groups, clarifying synonym relations, interpreting new classifications. For that reason, there is an intrinsic need to rely on a new process that combines:

the expertise of taxonomists contributing to well curated databases with global coverage;

recent knowledge compiled in checklists and catalogues published at regional and national scales in different formats and through different platforms;

new and improved informatics tools that can harvest those data with text mining schemas and integrate them into ChecklistBank and the COL Checklist based on revised and supported criteria and a careful quality control that will avoid the inclusion of errors or doubtful information.

Combining these elements would result in an extended release of the COL Checklist that is an enriched version, integrating a wider variety of taxonomic sources and informatic developments not considered previously. This process will feature sequential releases that will address different needs and will be useful for delivering taxonomic services for GBIF and ultimately replacing its backbone taxonomy (GBIF Secretariat 2022). The extended release of the COL Checklist will be more comprehensive, including names that will fill significant gaps, synonyms and fossil taxa, and a single consensus classification that avoids conflicts.
The Rhabdodontidae (Dinosauria, Ornithischia), an enigmatic dinosaur group endemic to the Late Cretaceous European Archipelago
Authors: Augustin Felix J. , Ősi Attila , Csiki-Sava Zoltán

The Rhabdodontidae was one of the most important dinosaur groups inhabiting the Late Cretaceous European Archipelago. Currently, the clade comprises nine species within six genera, which have been found in southern France, northern Spain, eastern Austria, western Hungary and western Romania, ranging from the Santonian to the late Maastrichtian. Phylogenetic analyses consistently place the Rhabdodontidae at the very base of the iguanodontian radiation, whereas the in-group relationships of rhabdodontids are relatively poorly understood; nevertheless, the clade seems to have had a rather complicated biogeographical history. Generally, rhabdodontids were small- to medium-sized, probably habitually bipedal herbivores, characterised by a rather stocky build and a comparatively large, triangular skull. Several lines of evidence suggest that they were presumably gregarious animals, as well as selective browsers that fed on fibrous plants and occupied different ecological niches than sympatric herbivorous dinosaur clades. Moreover, the sympatry of at least two rhabdodontid taxa was rather common and can be explained, at least in some instances, by niche partitioning. While rhabdodontids disappeared prior to the K/Pg extinction event in Western Europe, they survived close to the end of the Cretaceous in Eastern Europe, where they were amongst the last non-avian dinosaurs still present before the end of the Cretaceous. In this paper, we provide an overview of the rhabdodontid taxonomic history, diversity, phylogenetic relationships and palaeobiogeographic history, as well as palaeoecology and extinction. In addition, we also highlight still open questions on each of these topics and suggest potential future research directions.

Published: August 2023

This paper presents an investigation into the relationship between heart attacks and the Omicron variant, employing a novel mathematical model. The model incorporates two adjustable control parameters to manage the number of infected individuals and individuals with the Omicron variant. The study examines the model's positivity and boundedness, evaluates the reproduction number (R0), and conducts a sensitivity analysis of the control parameters based on the reproduction number. The model's parameters are estimated using the widely utilized least squares curve fitting method, employing real COVID-19 cases from Trkiye. Finally, numerical simulations demonstrate the efficacy of the suggested controls in reducing the number of infected individuals and the Omicron population.
Traces of certain integral operators related to the Riemann hypothesis
Authors: Sotelo-Pejerrey Alfredo
Published: August 2023

We prove the existence of a nontrivial singular trace $ \tau $ defined on an ideal $ \mathcal{J} $ closed with respect to the logarithmic submajorization such that $ \tau(A_\rho(\alpha)) = 0 $, where $ A_\rho(\alpha):L^{2}(0, 1)\to L^{2}(0, 1) $, $ {[A_\rho(\alpha)f](\theta) = \int^{1}_{0}\rho(\alpha\theta/x)f(x)dx} $, $ 0 < \alpha\leq 1 $. We also show that $ \tau(A_\rho(\alpha)) = 0 $ for every $ \tau $ nontrivial singular trace on $ \mathcal{J} $. Finally, we give a recursion formula from which we can evaluate all the traces $ {\mbox{Tr}}\, (A^{r}_{\rho}(\alpha)) $, $ r\in \mathbb{N} $, $ r\geq 2 $.

Industrial, electric railway, and automotive applications of inverters and converters use case-type semiconductor packages called power modules. Power modules have multiple joint points, and among them, from the viewpoint of reliability and bonding strength, many studies on metal-ceramic substrate bonding have been reported. Alumina Al203 or aluminum nitride AIN are mainly used for ceramics, and copper or aluminum are mainly used for metals, although alumina and aluminum have a price advantage. The joining methods are generally brazing and AMB (Active Metal Brazing), but there is a need to improve the joint strength, heat dissipation characteristics, and productivity, i.e., a joining method that does not use brazing material. The purpose of this study is to achieve direct joining of alumina A1203 and aluminum alloy A7075, and semi-solid forging [1, 2, 3, 4, 5, 6] was used as the method. The A7075 used in this study is considered to be suitable for this application because of its high strength and thermal conductivity among aluminum alloys. In this study, solid phase ratio 30 % semi-solid forging was actually performed using a servo press and a die, and the results were evaluated by observing the cross section of the fabricated specimens. The punches and dies were circular in shape to ensure uniform spreading of the molten material, and carbon steel S50C with high thermal conductivity was used to quickly dissipate the heat of the semi-solid slurry during the pressing process. The thickness of 99.6 % Al2O3 alumina plate was 2.5 mm. The semi-automatic stirring device was modified to stir the molten metal by attaching a 1000 mm round bar to the rotating part of a tabletop drilling machine and attaching a stirring blade to the tip of the bar. Debonding between aluminum alloy and alumina plate was not confirmed. There was no gap between the aluminum alloy and the ceramic plate.
