Published: June 2024

Intelligence is the most studied construct in psychology and cognitive neuroscience. In Brazil, the administration of intelligence tests is needed for a number of social rights, including driving privileges. Such requirements have led to a large testing industry but the vast majority of intelligence tests require extended administration times and language skills. In this study, we sought to investigate the psychometric properties and normative results of a new non-verbal intelligence test, the General Matrix of Intelligence (GMI). The GMI is comprised of 28 matrix-based items and can be administered in as little as six-minutes. In this initial pilot test, the GMI was administered to 1,326 participants, ages 15-64 years old (M = 25.65 years, SD = 9.6 years), from all regions in Brazil. These data were analyzed using a 2PL Item Response Theory model, regression analyses were conducted to determine the role of sociodemographic factors, and preliminary norms were computed. Results indicated a unidimensional solution that reproduced the g factor theory, invariance across genders, evidence that cognitively demanding items involving movement or three-dimensional shapes were more difficult than items with less cognitive load, a normal distribution for results, and an interaction between education level and age group in predicting performance. Implications of these findings for research and practice are discussed and all data and codes are provided at https://osf.io/kvu42/

Authors: Ahmed Toqeer , Mahmood Hifsa , Mushtaq Aniqa , Iftikhar Amina
Published: June 2024

This research article explores the portrayal of masculinity in Howard Jacobson’s novel, The Finkler Question, through a postmodern lens. It examines how the novel challenges traditional beliefs about masculinity and male identity, drawing on Jean-Francois Lyotard and Judith Butler to explore the fluid and contested nature of masculinity. Using textual analysis, the study focuses on themes of ageing, sexuality, and power in the portrayal of male characters and their relationships. The findings reveal that these characters navigate complex and contradictory identities, challenging conventional notions of masculinity. The novel critically reflects the socio-political context of contemporary Europe, highlighting diverse expressions of masculinity and the impact of societal expectations and traditional gender roles on male identity. Through its characters, the novel envisions a more inclusive and diverse understanding of male identity, emphasizing the fluid and evolving nature of masculinity. This study contributes to the ongoing discussion on gender and identity by demonstrating how The Finkler Question provides valuable insights into the nuanced nature of masculinity in contemporary Europe. The novel's critique of traditional masculinity underscores the need for a more inclusive understanding of male identity and highlights the importance of a postmodern perspective in grasping the fluid nature of masculinity in modern society.

Published: June 2024

Las relaciones entre turismo y medio ambiente son variadas. El turismo de bajo impacto puede contribuir eficazmente a mejorar las relaciones entre uno y otro, logrando que el desarrollo turístico y la protección del medio ambiente sean actividades complementarias. Algunos de los principales conflictos ambientales del turismo tienen que ver con el agua (la industria turística es una gran consumidora de agua), los residuos (descontrolados, afectan gravemente), el ruido y la degradación paisajística (el turismo es un gran consumidor de paisaje). El presente trabajo tiene como objetivo general analizar el trabajo de la educación ambiental en los impactos que ocasiona el turismo en la bahía de Cienfuegos. Para el desarrollo de la investigación se ha utilizado el enfoque cualitativo, apoyándose en técnicas como el análisis de documentos y la entrevista en profundidad. Entre los resultados se aprecia un aumento de turbidez en las aguas de la bahía y, cierta apatía y desinterés por el cuidado ambiente por parte de los ciudadanos. El turismo ambiental no está sólo para que se puedan cumplir las funciones de amortiguador ecológico y reproductor natural, sino también, para ofrecer nuevas perspectivas duraderas de desarrollo responsable y sostenible en el tiempo, para el disfrute de todos.

Published: June 2024

The primary objective of this study is to identify the discrepancies between the required and current levels of NCS(National Competency Standards) among graduates from four-year universities. Subsequently, this study aims to elucidate the implications of developing and implementing NCS-based curricula in universities to enhance the fundamental vocational abilities of college students. To achieve this, a survey was conducted among 195 individuals who graduated from four-year universities and are currently employed to determine the required and current levels of vocational fundamental proficiencies as defined by the National Competency Standards(NCS). The paired sample t-test, Borich analysis, and Hershkowitz Critical function were then employed to analyze the discrepancies between the two levels. The findings of this study indicate that firstly, among the 34 areas of NCS (National Competency Standards), graduates demonstrated statistically significant discrepancies between the necessary state and the current state in document writing ability, expression ability, basic foreign language ability, basic arithmetic ability, thinking ability, problem-solving ability, self-management ability, career development ability, time resource management ability, budget resource management ability, leadership ability, conflict management ability, negotiation ability, information processing ability, technical understanding ability, technical application ability, and job comprehension ability.
Secondly, it was determined that basic foreign language ability and expression ability within the sub-abilities of communication, career development ability, and self-management ability within the sub-abilities of self-development, and conflict management ability and negotiation ability within the sub-abilities of interpersonal communication should be given the highest priority in the consideration process. Based on the findings, it is recommended that a comprehensive consideration of the educational needs perceived by graduates be taken into account when developing and applying NCS-based education programs. It is expected that this will serve as important foundational data for effectively developing the NCS basic vocational skills of future university students.

Published: June 2024

This study aims to develop a technology holding company model to activate entrepreneurship and facilitate technology commercialization in the field of marine and fisheries science and technology. By comprehensively analyzing the current status and policies of public technology entrepreneurship in Korea, the growth potential of the marine and fisheries market, and the current situation and challenges faced by marine and fisheries science and technology, this study seeks to explore concrete measures to promote the commercialization of public technology and entrepreneurship in this field. In particular, in the marine and fisheries field, technology commercialization and entrepreneurship of research and development results are insufficient, so it is analyzed that revitalization of entrepreneurship through the technology holding company model is necessary. Based on Isenberg's startup ecosystem model, this study analyzed the current status of technology commercialization and startup factors through in-depth interviews and surveys with researchers at the Korea Institute of Ocean Science and Technology, and analyzed the feasibility of establishing a technology holding company. The research results suggest that an integrated approach is needed in which six major elements of policy, market, human capital, support, funding, and culture interact to revitalize marine and fisheries science and technology startups. In order to activate the interaction of the six major components, the establishment of a technology holding company such as 'KIOST Holdings' is necessary. Government and related agencies need to expand R&D support, provide incentives for entrepreneurship and technology commercialization, and establish legal and financial support systems for technology holding companies and research-based startups. Such support will lay the foundation for the sustainable development and global competitiveness of the marine and fisheries science and technology sector. The introduction of a technology holding company model for activating entrepreneurship in marine and fisheries science and technology is expected to play a crucial role in the sustainable development and enhancement of global competitiveness in the marine industry. This study suggests that the establishment of technology holding companies like 'KIOST Holdings' could serve as a foundation for implementing these strategies, marking an important step towards overcoming the limitations of Korean marine and fisheries science and technology and activating entrepreneurship and technology commercialization in this sector.
A Study on the Development Plan of Creative Economy Innovation Center
Authors:   The Korean Career·Entrepreneurship & Business Association, Nam Jungmin , Kim Gayeon,
Published: June 2024

This study selected 17 regional creative economic innovation centers, excluding two private autonomous innovation centers, out of a total of 19 nationwide, and conducted case studies based on previous studies, articles, center websites, internal data, and interviews with practitioners.
To establish the identity of Creative Economy Innovation Centers as regional startup hubs and drivers of local innovation, it is necessary to redefine their roles not only through collaboration with universities but also through realigning their roles with relevant local institutions. Secondly, it was observed that most of the investment resources for Creative Economy Innovation Centers remain in the form of initial funding support. To facilitate the scale-up of early-stage startups, it is necessary to develop qualitative improvement measures from various perspectives, including support tailored to specific businesses and growth stages. Additionally, in response to the strengthening global and domestic ESG regulations, centers should consider implementing customized ESG management education and certification support for startups, as well as mentoring programs. Thirdly, to reduce regional disparities, Creative Economy Innovation Centers should actively operate open programs specific to each center and allocate budgets that allow for flexible engagement in collaborative projects within their internal structure. Policy measures are needed to address the issue of regional decline by considering business initiatives for local youth, which also contribute to the sustainability of startups. Furthermore, there is a need to expand educational programs and policy support for “born-global” startups that target niche global markets from the early stages of entrepreneurship.
This study is meaningful in confirming and verifying that the various attempts and efforts needed to build a regional innovation start-up ecosystem, as well as quantitative results on supporting the growth of startups and existing local SMEs discovered and fostered through the Creative Economy Innovation Center, as well as job creation and maintenance based on regional economic growth, need to be maintained and developed continuously.

Importance: Assessment of praxis skills is an essential aspect of understanding autistic children’s development of play and playfulness.

Objective: To assess the relationship and influence of ideational praxis skills on play skills and playfulness among autistic children.

Design: A cross-sectional study.

Settings: Homes, schools, and early care centers across Spain.

Participants: Children ages 4 yr 6 mo to 6 yr 11 mo (45 typically developing [TP] and 45 with autism spectrum disorder [ASD]).

Outcomes and Measures: Student’s t tests were used to compare means between the two groups. Pearson’s correlation and multiple linear regression were used to determine possible effects of ideational skills on play and playfulness.

Results: Scores for the TP group were significantly higher than those of the ASD group on all play dimensions—space management, t(88) = 4.58; material management, t(88) = 5.86; pretense–symbolism, t(88) = 8.12; and participation, t(88) = 7.31—and on the Test of Playfulness (ToP), t(88) = 10.18, and Test of Ideational Praxis (TIP), t(88) = 4.38 (all ps < .001). Multiple linear regression revealed a statistically significant effect of TIP dimensions—space management, F(3, 41) = 4.83, p < .042; material management, F(3.41) = 8.49. p < .001; pretense–symbolism, F(3, 41) = 5.66. p < .002; and participation, F(3.41) = 7.81. p < .001—and on the ToP, F(3, 41) = 5.96. p < .002.

Conclusions and Relevance: Ideational praxis skills combined with diagnostic information significantly predicted play skills and playfulness, highlighting the influence of ideation on play.

Plain-Language Summary: This article provides data supporting the influence of ideational praxis skills on the play skills and playfulness of autistic children. Understanding how ideational praxis skills affect the ability to recognize and act on object affordances might promote greater possibilities for play interactions among autistic children.
A Morphological Perspective on Educating the History of Korean Language
Authors:   Morphology, Kim Yu-pum
Published: June 2024

This paper examines educating the history of Korean language from the perspective of morphology. Although the current school grammar is very limited in terms of the history of Korean language, the changes in the school grammar according to the needs of the times draw attention to the importance of educating the history of Korean language and expect a new role. Among the educational contents that I think are necessary for better educating the history of Korean language in school grammar, I looked at four topics related to morphology: 1)phonological inventory and the basic forms of morphemes, 2)the loss and return of /k/, 3)loose and strict compounds, and 4)traditional life vocabulary reflecting culture. These topics provide a valuable opportunity to rediscover the meaning and importance of morphology in educating the history of Korean language, as well as to better understand the history of Korean language through morphology.

Authors: Öten Mehmet , Köse Melike
Published: June 2024

This research was conducted at Sakarya University of Applied Sciences, Faculty of Agriculture’ Field Crops Laboratory. The aim of the study to determine the effects of three different silage additives (molasses (M), whey (W), and citrus pulp (CiP)), added to pure and mixtures of common vetch (Vicia sativa L.)+triticale (xTriticosecale Wittmack) in different proportions on silage quality. The plants materials under investigation were mixed in ratios of 25%, 50%, 75% and 100%. Silages and mixtures were established with three replications, and three different silage additives were applied to each mixture. These additives included 4% molasses, 3% whey, and 2% citrus pulp. Silages were analyzed for crude protein (CrP), acid detergent fiber (ADF), neutral detergent fiber (NDF), dry matter (DM), pH, crude ash (CA), as well as phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) contents. Additionally, flieg score and physical analysis criteria (odor, color, and structure) were determined. Considering the interaction of silage mixture ratio and additive, statistically significant differences were observed among silages in parameters such as CP, K, P, and pH at a 1% level and among silages in parameters such as CA, ADF, NDF, Ca, Mg, and DM at a 5% level. As a result of the analysis, the highest CP, ADF and NDF content; Obtained from 17.51% silage mixture (75%V+25%T)+CiP, 40.81% from silage mixture (50%V+50%T)+M and 57.46% from silage mixture (50%V+50%T)+CiP were respectively. According to physical analysis criteria; It was determined that silage quality varied between 3.75-18.25. In parallel with the increase in the vetch ratio in the silage mixture; It was determined that the contents of crude protein, crude ash, K, P, Mg and Ca were positively affected, while the pH value was negatively affected. It was observed that the NDF content was low and the Mg content was high in the silages to which molasses was added. Consequently, it can be said that making silage in the form of a legume-cereal mixture rather than in pure form positively affects silage quality, and the addition of additives to mixed silages has a positive effect on silage quality.

Abstract. The anticipated increase in solar energy production in West Africa requires high-quality solar radiation estimates, which is affected by meteorological conditions and in particular the presence of desert dust aerosols. This study examines the impact of incorporating desert dust into solar radiation and surface temperature estimations. The research focuses on a case study of a dust event in March 2021, which is characteristic of the dry season in West Africa. Significant desert aerosol emissions at the Bodélé depression are associated with a Harmattan flow that transports the plume westwards. Simulations of this dust event were conducted using the WRF meteorological model alone, as well as coupled with the CHIMERE chemistry-transport model, using three different datasets for the dust aerosol initial and boundary conditions (CAMS, GOCART, MERRA2). Results show that considering desert dust reduces estimation errors in global horizontal irradiance (GHI) by about 75 %. The dust plume caused an average 18 % reduction in surface solar radiation during the event. Additionally, the simulations indicated a positive bias in aerosol optical depth (AOD) and PM10 surface concentrations. The choice of dataset for initial and boundary conditions minimally influenced GHI, surface temperature, and AOD estimates, whereas PM10 concentrations and aerosol size distribution were significantly affected. This study underscores the importance of incorporating dust aerosols into solar forecasting for better accuracy.

Abstract. The eruptions of the Tajogaite volcano on the western flank of the Cumbre Vieja ridge on the island of La Palma between September and December 2021 released large amounts of ash and SO2. Transport and dispersion of the volcanic emissions were monitored by ground-based stations and satellite instruments alike. In particular, the spectrometric fluorescence and Raman lidar RAMSES at the Lindenberg Meteorological Observatory measured the plume of the strongest Tajogaite eruption of 22–23 September 2021 over northeastern Germany four days later. This study provides an analysis of SO2 vertical column density (VCD) and layer height (LH) measurements of the volcanic plume obtained with Sentinel-5 Precursor/TROPOMI, which are compared to the observations at several stations across the Canary Islands. Furthermore, a new modeling approach based on TROPOMI SO2 VCD measurements and the HYSPLIT trajectory and dispersion model was developed which confirmed the link between Tajogaite eruptions and Lindenberg measurements. Modeled mean emission height at the volcanic vent is in excellent agreement with co-located TROPOMI SO2 LH and local lidar ash height measurements. Finally, a comprehensive discussion of the RAMSES measurements is presented. A new retrieval approach has been developed to estimate the microphysical properties of the volcanic aerosol. For the first time, an optical particle model is utilized that assumes an irregular, non-spheroidal shape of the aerosol particles. According to the analysis, the volcanic aerosol consisted solely of fine-mode inorganic, solid and irregularly shaped particles – the presence of large aerosol particles or wildfire aerosols could be excluded. The particles likely had an isometric to slightly plate-like shape with an effective half of particle maximum dimension around 0.1 μm and a refractive index of about 1.51. Moreover, mass column values between 70 and 110 mg m-2, mean mass concentrations of 45–70 μg m-3, and mean mass conversion factors between 0.21 and 0.33 g m-2 at 355 nm were retrieved. Possibly RAMSES observed, at least in part, volcanic secondary sulfate aerosol which was produced by gas-phase homogeneous reactions during the transport of the air masses from La Palma to Lindenberg.
Using machine learning algorithm to retrieve cloud fraction based on FY-4A AGRI observations
Authors: Xia Jinyi , Guan Li
Published: June 2024

Abstract. Cloud fraction as a vital component of meteorological satellite products plays an essential role in environmental monitoring, disaster detection, climate analysis and other research areas. A long short-term memory (LSTM) machine learning algorithm is used in this paper to retrieve the cloud fraction of AGRI (Advanced Geosynchronous Radiation Imager) onboard FY-4A satellite based on its full-disc level-1 radiance observation. Correction has been made subsequently to the retrieved cloud fraction in areas where solar glint occurs using a correction curve fitted with sun-glint angle as weight. The algorithm includes two steps: the cloud detection is conducted firstly for each AGRI field of view to identify whether it is clear sky, partial cloud or overcast cloud coverage within the observation field. Then the cloud fraction is retrieved for the scene identified as partly cloudy. The 2B-CLDCLASS-LIDAR cloud fraction product from Cloudsat& CALIPSO active remote sensing satellite is employed as the truth to assess the accuracy of the retrieval algorithm. Comparison with the operational AGRI level 2 cloud fraction product is also conducted at the same time. During daytime, the probability of detection (POD) for clear sky, partly cloudy, and overcast scenes in the official operational cloud detection product were 0.5359, 0.7041, and 0.7826, respectively. The POD for cloud detection using the LSTM algorithm were 0.8294, 0.7223, and 0.8435. While the operational product often misclassified clear sky scenes as cloudy, the LSTM algorithm improved the discrimination of clear sky scenes, albeit with a higher false alarm rate compared to the operational product. For partly cloudy scenes, the mean error (ME) and root-mean-square error (RMSE) of the operational product were 0.2374 and 0.3269. The LSTM algorithm exhibited lower ME (0.1134) and RMSE (0.1897) than the operational product. The large reflectance in the sun-glint region resulted in significant cloud fraction retrieval errors using the LSTM algorithm. However, after applying the correction, the accuracy of cloud cover retrieval in this region greatly improved. During nighttime, the LSTM model demonstrated improved POD for clear sky and partly cloudy scenes compared to the operational product, while maintaining a similar POD value for overcast scenes and a lower false alarm rate. For partly cloudy scenes at night, the operational product exhibited a positive mean error, indicating an overestimation of cloud cover, whereas the LSTM model showed a negative mean error, indicating an underestimation of cloud cover. The LSTM model also exhibited a lower RMSE compared to the operational product.
Impact of horizontal resolution and model time step on European precipitation extremes in the OpenIFS 43r3 atmosphere model

Abstract. Events of extreme precipitation pose a hazard to many parts of Europe but are typically not well represented in climate models. Here, we evaluate daily extreme precipitation over Europe during 1982–2019 in observations (GPCC), reanalysis (ERA5) and a set of atmosphere-only simulations at low- (100 km), medium- (50 km) and high- (25 km) horizontal resolution with identical vertical resolutions using OpenIFS (version 43r3). We find that both OpenIFS simulations and reanalysis underestimate the rates of extreme precipitation compared to observations. The biases are largest for the lowest resolution (100 km) and decrease with increasing horizontal resolution (50 and 25 km) simulations in all seasons. The sensitivity to horizontal resolution is particularly high in mountain regions (such as the Alps, Scandinavia, Iberian Peninsula), likely linked to the sensitivity of vertical velocity to the representation of topography. The sensitivity of precipitation to model resolution increases dramatically with increasing percentiles, with modest biases in the 70th–80thpercentile range and large biases above the 99th percentile range. We also find that precipitation above the 99th percentile mostly consists of large-scale precipitation (~80 %) in winter, while in summer it is mostly large-scale precipitation in Northern Europe (~70 %) and convective precipitation in Southern Europe (~70 %). Compared to ERA5, the OpenIFS overestimates large-scale precipitation extremes in winter, but underestimates in summer. The discrepancy between OpenIFS and ERA5 decreases with increasing horizontal resolutions. We also examine the sensitivity of extreme precipitation to model time step and find that the convective contribution to extreme precipitation is more sensitive to the model time step than the horizontal resolution. This is likely due to the sensitivity of convective activity to model time step. On the other hand, the large-scale contribution to extreme precipitation is more sensitive to horizontal resolution than the model time step, which may be due to sharper fronts and steeper topography at higher horizontal resolution.
A sensitivity-based estimation method for investigating control co-design relevance

Abstract. Control co-design is a promising approach for wind turbine design due to the importance of the controller in power production, stability, load alleviation, and the resulting coupled effects on the sizing of the turbine components. However, the high computational effort required to solve optimization problems with added control design variables is a major obstacle to quantifying the benefit of this approach. In this work, we propose a methodology to identify if a design problem can benefit from control co-design. The estimation method, based on post-optimum sensitivity analysis, quantifies how the optimal objective value varies with a change in control tuning. The performance of the method is evaluated on a tower design optimization problem, where fatigue load constraints are a major driver, and using a linear quadratic regulator targeting fatigue load alleviation. We use the gradient-based multi-disciplinary optimization framework Cp-max. Fatigue damage is evaluated with time-domain simulations corresponding to the certification standards. The estimation method applied to the optimal tower mass and optimal cost of energy show good agreement with the results of the control co-design optimization while using only a fraction of the computational effort. Our results additionally show that there may be little benefit to using control co-design in the presence of an active frequency constraint. However, for a soft–soft tower configuration where the resonance can be avoided with active control, using control co-design results in a taller tower with reduced mass.

Abstract. This paper investigates different actuator sector model implementation alternatives and how they compare to actuator line results. The velocity sampling method, tip/smearing correction, and time step are considered. A good agreement is seen between the line and sector model in the rotor plane and the wake flow. Using the sector model, it was possible to reduce the computational time by 75 % compared to the actuator line model as it is possible to run the simulations with a larger time step without compromising the accuracy considerably. The results suggest that the proposed velocity sampling method produces the closest results to the line model with different tip speed ratios. Moreover, the vortex-based smearing correction applied to the sector model results in the lowest error values, among the considered methods, to correct the radial load distributions. Also, it is seen that reducing the time step compared to the one used for the actuator disc/sector does not provide an advantage considering the increased computational time.

Electrical installations are prone to disturbances, both short circuits and overloads, for this reason protection is needed in home electrical installations. MCB or mini circuit breaker is generally widely used as protection in electrical installations how the MCB works. When there is an overload disturbance, the MCB will cut off the electric current flowing in the electrical installation. In this study, researchers will create a prototype that will detect overload disturbances that occur in electrical installations. The advantage of developing this prototype is that the flow can be monitored. The prototype consists of Arduino ATmega 328, ACS712 sensor, relay, push button. The way this tool works is when there is a disturbance in the electrical installation the ACS712 sensor will detect a current which will then send the signal to the Arduino and the relay. The current value will be displayed on the LCD screen. This prototype contributes an overload protection equipped with current monitoring which can later be used by household applications.

This study presents a nonlinear deterministic mathematical model of Human Papillomavirus (HPV) dynamics, emphasizing qualitative analysis through the stability theory of differential equations. Our investigation focuses on validating the existence and stability of disease-free and endemic equilibrium points using the basic reproduction number governing HPV transmission. Notably, the model exhibits a backward bifurcation, prompting a sensitivity analysis. We address the challenge of HPV control by formulating an optimal control problem, applying the Pontryagin maximum principle with three distinct strategies: prevention, treatment, and screening. Numerical simulations reveal that a combined approach involving prevention, screening, and treatment emerges as the most effective strategy for eradicating HPV within the community. In conclusion, this study offers a comprehensive mathematical model for HPV dynamics and underscores the importance of multi-faceted intervention strategies. Our findings have significant implications for public health initiatives aiming to combat HPV infections and reduce their impact on communities.
