Authors: Nocillado J , Gilligan D , Fielder S , Dennis LP , Wang T , Ventura T , Elizur A
Published: June 2023

The Macquarie perch Macquaria australasica is an endangered freshwater fish endemic to the Murray-Darling Basin in Australia. Captive breeding is considered an essential measure to save the species from extinction, yet its reproductive biology is not fully understood. We produced a recombinant single-chain Macquarie perch luteinizing hormone (rmpLh) in the methylotrophic yeast Pichia pastoris, confirmed by Western blot analysis and mass spectrometry. We developed and validated a heterologous competitive enzyme-linked immunosorbent assay (ELISA) for M. australasica Lh using antibodies generated against the giant grouper Epinephelus lanceolatus Lhb, which is 91% identical to the M. australasica sequence at the amino acid level. Measurement of Lh in plasma samples collected at 2 timepoints (June vs. August 2020) from captive F1 broodstock did not show a significant difference. Plasma Lh in samples from wild fish collected in September 2020, a month prior to the spawning season, were almost 10-fold higher than those of the F1 broodstock. The tools generated here will help us to understand the reproductive biology of M. australasica and develop reliable assisted reproduction techniques for the species.
Hippocampal vasopressin release evoked by N-methyl D-aspartate (NMDA) microdialysis
Authors: Orłowska-Majdak M , Traczyk WZ , Szymański D
Published: June 2023

Hippocampus is a brain structure containing vasopressin (AVP) fibers and specific binding sites for this peptide. There is growing evidence that AVP and its metabolites participate in glutamate-mediated plasticity of the hippocampus. The aim of the present study was to evaluate the influence of NMDA on AVP release in the rabbit hippocampus. Caudate nucleus was chosen as the reference structure. The mentioned brain structures were simultaneously microdialyzed with 0.9 % NaCl solution. AVP was determined in the outflowing fluid by radioimmunoassay. The mean basal AVP content in the fluid outflowing from the hippocampus was significantly greater than that from the caudate nucleus. The addition of K+ into the fluid perfusing the probes implanted into the hippocampus and caudate nucleus significantly increased AVP release into the extracellular fluid of both brain structures. NMDA applied into the mentioned brain structures increased AVP release only from the hippocampus but not from the caudate nucleus. Our findings indicate a role which NMDA receptors play in AVP release into the extracellular fluid of the hippocampus.

Published: June 2023

Our and other studies suggest that myocardial hypertrophy in response to hypertension and hyperthyroidism increases propensity of the heart to malignant arrhythmias, while these are rare in conditions of hypothyroidism or type-1 diabetes mellitus associated with myocardial atrophy. One of the crucial factors impacting the susceptibility of the heart to life-threatening arrhythmias is gap junction channel protein connexin-43 (Cx43), which ensure cell-to-cell coupling for electrical signal propagation. Therefore, we aimed to explore Cx43 protein abundance and its topology in hypertrophic and hypotrophic cardiac phenotype. Analysis were performed in left ventricular tissue of adult male spontaneously hypertensive rat (SHR), Wistar Kyoto rats treated for 8-weeks with L-thyroxine, methimazol or strepotozotocin to induce hyperthyroid, hypothyroid and type-1 diabetic status as well as non-treated animals. Results showed that comparing to healthy rats there was a decrease of total myocardial Cx43 and its variant phosphorylated at serine368 in SHR and hyperthyroid rats. Besides, enhanced localization of Cx43 was demonstrated on lateral sides of hypertrophied cardiomyocytes. In contrast, total Cx43 protein and its serine368 variant were increased in atrophied left ventricle of hypothyroid and type-1 diabetic rats. It was associated with less pronounced alterations in Cx43 topology. In parallel, the abundance of PKCɛ, which phosphorylates Cx43 at serine368 that stabilize Cx43 function and distribution was reduced in hypertrophied heart while enhanced in atrophied once. Findings suggest that differences in the abundance of cardiac Cx43, its variant phosphorylated at serine368 and Cx43 topology may explain, in part, distinct propensity of hypertrophied and atrophied heart to malignant arrhythmias.

Published: June 2023

Background and aims. The principles of enhanced recovery in operative gynecology, comorbidity, and a multimodal approach in perioperative support require comprehensive study and optimization, and the ambiguity of literature reports determines the relevance of this study. The aim of this study was to evaluate the parameters of perioperative monitoring after hysterectomy for uterine leiomyoma in patients of reproductive age using enhanced recovery after surgery protocols and their impact on quality of life indicators. Materials and methods. To evaluate the effectiveness of the enhanced recovery protocol after hysterectomy, two groups were formed: the main prospective group, which included 46 patients, who underwent vaginal hysterectomy without appendages and 36 patients with abdominal hysterectomy, who used enhanced recovery after surgery (ERAS) protocols. The comparison group (group of standard management) included 44 patients who underwent vaginal hysterectomy without appendages and 34 patients with abdominal hysterectomy. The main parameters of monitoring were the postoperative pain level, intraoperative blood loss, diuresis rate, the timing of urinary catheter removal and recovery of peristalsis, as well as individual activation of motor activity. Results. When using the principles of ERAS, the quantitative assessment of pain level (“absence of pain”) was 1.6 times more severe compared to the data of the comparison group; the timing of urinary catheter removal was 2.0 times shorter, drain removal – 2.7 times shorter, recovery of peristalsis – 1.9 times shorter and individual activation of motor activity – 2.9 times earlier than in patients of the comparison group. Conclusions. Studies have demonstrated the feasibility of using laparoscopic technology in combination with the ERAS, which demonstrates a fall in the volume of intraoperative blood loss, a decrease in blood and fluid balance, a shortening of the time of invasive intravascular intervention, allows to improve the course of the early postoperative period, relieve postoperative pain syndrome, reduce the risk of intestinal paresis, shorten the rehabilitation period, and, as a result, improve quality of life indicators.

‘Metaverse Ethical Principles’ and ‘Human Ethics’ Linked by ‘Integrity’
Authors:   The Korean Society of Culture and Convergence, Shim Jiwon , Kim Jin-sun
Published: June 2023

Avatar is a prominent feature that distinguishes the metaverse from the existing technology environment. Agents who stay in reality operate in the metaverse by using avatars. The real self and the self expressed as an avatar exist in different areas, but are not completely separated. Accordingly, the “Metabus Ethics Principles for the Realization of a Digital Trust Society” announced by the Ministry of Science and ICT in 2022 puts forward the “Sincere Identity,” that is, “integrity,” as the main orientation value. In this paper, we would like to emphasize the value of integration while examining the characteristics of the metaverse. In addition, this can be emphasized through the fact that various technical ethics contain the characteristics of the technology but are based on the content that is mainly dealt with in the existing ethics. As a result, we would like to argue that metaverse ethics should not be treated like a “new ethics” completely separated from the context in which ethics in the real world are placed, and that it is still human ethics.

Authors:   The Korean Society of Culture and Convergence, Lee Sanghee , Yoo Byungcheol
Published: June 2023

The purpose of this study is to examine the effects of internal marketing on job satisfaction, emotion mismatch, and customer orientation among them for secondary financial employees. The competence and motivation of internal employees have been in the spotlight as their duties have expanded to include a wide range of tasks from simple customer service to professional guidance. The results of the study confirmed that the strengthening of internal marketing has a positive effect on job satisfaction (H1) and customer orientation (H3), but no effect on emotion mismatch (H2). In addition, it found that job satisfaction has a positive effect on customer orientation (H4) and emotion mismatch has a negative effect on customer orientation (H5). This study is differentiated from existing studies in that it focuses on the secondary financial sector, which has been under-researched compared to the primary financial sector, and is significant in that it shows through empirical analysis that internal marketing is necessary to enhance competitiveness in the secondary financial sector, and that if the secondary financial sector wants to achieve performance, it is necessary to provide information that is actually helpful to customers before strengthening efforts to increase customer orientation.

Authors:   The Korean Society of Culture and Convergence, Kim Keun-Hyang
Published: June 2023

The present study examined which personality traits are vulnerable to boredom by exploring the relationship between 6 factors of boredom proneness and personality (HEXACO model). We collected data from 168 university students and conducted a multiple regression analysis. The analysis showed that extraversion, openness, and conscientiousness were significantly negatively related to internal boredom proneness, with these three factors explaining about 47% of the variance. Honesty/humility, extraversion, and agreeableness were also significantly negatively related to external boredom proneness, explaining about 22% of the variance. Extraversion showed significant relationships with both boredom proneness factors. This study enhances our psychological understanding of the effects of interanal and exteranal boredom proness on the six personality factors of HEXACO model, highlighting the need for future a multidimensional reseach on boredom.
A Study of Rousseau’s View of Happiness and Humam Education
Authors:   The Korean Society of Culture and Convergence, Jeong Eun Ju
Published: June 2023

The purpose of this paper is to examine the relationship between happiness and education, focusing on Rousseau's books. To this end, his view of happiness and the purpose of education were examined, focusing on the contents of happiness and education in his major works. Rousseau told children not to use competition, jealousy, and fear as a means of education. This is because self-love necessary for self-preservation turns into selfishness and becomes the source of unhappiness. He also made 'human and citizen' his educational goal. The teacher guaranteed the child's freedom as an authoritative leader and led the child to discover knowledge and value as a free being. This is because the balance of duty as a citizen and life as an individual is the foundation of happiness.

Authors:   The Korean Society of Culture and Convergence, Oh Han-Seung
Published: June 2023

In this paper, based on the style theory of Schusterman, a researcher of pragmatic aesthetics, the style of K-POP choreography and the self-styling of cover dance performed by fans were examined. Among the factors that have contributed to K-POP's global popularity and lasting influence, the choreography style of the detailed emotions and inherent impulses expressed by K-POP choreography is the most important, and global K-POP fans are fascinated by this choreography style and feel the desire to express it with my own body. This desire is triggered by kinesthetic empathy and mirrors K-pop choreography directly through community dance to make it self-styled. The K-pop choreography style embodied through the cover dance of K-POP choreography can be experienced and understood by the public, and can become a communication channel that can trigger re-creation.
When are Junctures Critical? The Legacies and Non-Legacies of Interruptions in Local Self-Government
Authors: Gingerich Daniel W. , Vogler Jan
Published: June 2023

Interruptions in local self-government are a common feature of imperial rule and centralized authoritarianism. Extant scholarship considers interruptions in both contexts as potentially legacy-producing. But under which circumstances do these denials of political autonomy lead to sustained changes in political behavior? We develop a novel framework that elucidates when interruptions in local self-rule will or will not produce political legacies. Two factors are crucial: the duration of an interruption and the scope of repression. Enduring interruptions characterized by encompassing repression are the most likely to generate persistent changes. Contrariwise, transient interruptions characterized by limited repressiveness are unlikely to produce legacies. Given our theory's broad character, we conduct empirical analyses in two markedly different settings: Poland, which was split between three major empires, and Brazil, where a military regime installed appointed mayors in certain cities. Our results demonstrate that interruptions in local self-government have varying potential to create legacies.

Indonesia is the 3rd ranked country with the highest number of TB cases in the world, namely 845,000 cases in 2020. In the same year, the number of suspected TB in East Java was 42,922 cases and Sumenep Regency was in the 11th position with the most TB with 1,924 cases. Therefore, community service activities aim to carry out training for TB cadres at the Bluto Health Center as an effort to reduce TB cases. Community service activities are carried out from April to July 2022. Activities begin with planning, obtaining permits, coordination meetings, training preparations, conducting webinars, conducting face-to-face training, pre-test and post-test evaluations. Activities went well. The impact of implementing training activities was in the form of 93% of cadres experiencing an increase in knowledge and the other 7% experiencing a decrease in knowledge. These good results can be used as a basis for local health workers to continue activities to increase the knowledge and skills of cadres using the lecture method; question and answer; health promotion media in the form of videos; and direct practice. Cadres can also use the same method to educate the target community regarding TB, how to prevent and treat it.
Valorizing meat by-products for human consumption: understanding consumer attitude formation processes
Authors: Lavranou Georgia , Henchion Maeve , McCarthy Mary B. , O’Reilly Seamus J.
Published: June 2023

Introduction

A considerable body of research has identified that meat by-products contain significant amounts of high-quality protein, which when properly extracted can lead to valuable opportunities for the food industry. However, the market success of food products containing protein extracted from meat byproducts is subject to consumer acceptance. This study explores Irish consumers’ attitudes toward hypothetical food products containing protein derived from beef offal sources.

Methods

A nationally representative survey (n = 953) was undertaken to investigate what attitude processes, that is intuitive and/or deliberative, dominate attitude formation toward food products containing beef offal-derived protein, while accounting for the effects of product familiarity and information provision. Using a 2 x 3 between-subject design, study participants were randomly assigned to one of the 6 study conditions. Participants were exposed to Affect Misattribution Procedure (AMP) tasks which measured their intuitive evaluations, followed by a number of questions that measured deliberative evaluation, attitude ambivalence, attitudes and acceptability toward the food products containing protein extracted from beef offal.

Results

The study reveals that consumers’ intuitive and deliberative evaluations worked in the same direction, predicting overall attitudes toward these products; however, deliberative evaluation was found to be a better predictor of consumers’ attitudesthan intuitive evaluation. Moreover, intuitive evaluations do not influence deliberative evaluations, suggesting that information provision that prompts deliberative evaluations could lead to the formation of more considered and stable attitudes. Familiarity influences acceptance: these findings suggest that the potential impact of a lack of familiarity with the ingredient is offset by familiarity with the carrier products. Consumers who received benefit information about the health and environmental consequences of consuming food products containing protein extracted from beef offal expressed a more positive deliberative attitude toward these products. However, interestingly, the provision of benefit- and risk-orientated information at the same time at the same time also had a positive effect on deliberative evaluations.

Discussion

The findings have implications for new product development, and more generally for strategies that seek to promote sustainable food production and consumption.

Background

The relationship between acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) and cardiac function is not well established. This study aimed to evaluate whether AML patients exist early myocardial damages prior to chemotherapy and to investigate its association with cardiovascular biomarkers.

Methods

Conventional echocardiography and three-dimensional speckle-tracking strain analysis were performed prospectively in 72 acute leukemia (AL) patients before any chemotherapy therapy (of whom 44 were AML patients, 28 ALL patients). The results were compared with those from 58 control group matched for age and gender.

Results

There were no significant differences in conventional biventricular systolic function parameters between AL patients and controls. The left ventricular global longitudinal strain (LVGLS) and right ventricular free wall longitudinal strain (RVFWLS) were significantly lower in AL patients (−23.0 ± 1.4% vs. −24.1 ± 1.3% and −27.9 ± 7.1% vs. −33.0 ± 4.6%, respectively, P < 0.001 for all). Compared with ALL patients, AML patients had lower LVGLS and RVFWLS (−22.7 ± 1.3% vs. −23.5 ± 1.6% and −26.2 ± 7.6% vs. −30.4 ± 5.5%, respectively, P < 0.05 for all). LVGLS was lower in ALL patients compared with controls (−23.5 ± 1.6% vs. −24.7 ± 1.4%, P < 0.05), however, there was no difference in right ventricular systolic function parameters between the two groups. LVGLS in AL patients was independently correlated with left ventricular ejection fraction (LVEF) and the absolute number of circulating lymphocytes.

Conclusions

Our findings suggest that baseline myocardial systolic function is lower in AL patients than controls. AML patients had lower baseline LVGLS and RVFWLS than controls and ALL patients. The decreased LVGLS is correlated with LVEF and the absolute number of circulating lymphocytes.

Published: June 2023

Rain-induced loess landslides are especially prevalent in the Chinese Loess Plateau (CLP). Some became fatal landslide disasters, leading to numerous casualties and significant socioeconomic losses. Extreme precipitation is the main cause of landslide occurrence. Therefore, in this study we discuss the correlation between seven extreme precipitation indices, single continuous precipitation events and fatal landslides in the CLP using Pearson correlation analysis. We also predict future precipitation under climate changes using five optimal CMIP6 models. During the period 2004–2016, fatal landslides in the CLP increased at a rate of 0.6 per year, with frequent landslide events occurring especially in the central and southwestern parts of the CLP. We find that SDII (simple daily intensity precipitation index) and R×5day (max 5-day precipitation amount) show spatial distribution that are consistent with fatal landslides. Extreme precipitation events were frequent after year 2000; and several extreme precipitation indices show an increasing trend with a higher magnitude since 2000 than before 2000. In particular, in 2013 when the number of fatal landslides was as high as 17, SDII, R95pTOT (extremely wet days), R25mm (very heavy precipitation days), and R×5day all showed abrupt increases. Single continuous precipitation events have profound effects on fatal landslides. We show that single continuous precipitation events with cumulative precipitation of 185–235 mm and duration of 6 days or longer have the highest correlation with fatal landslides. As the increasing occurrence of extreme rainfall events by the global warming, the CLP may face more fatal landslides in the future, especially in the high emission scenario of greenhouse gases (GHGs).

Accurately predicting oxygen mass transport resistance and current distribution in fuel cells requires significant knowledge of oxygen diffusion coefficients in both in-plane and through-plane directions. However, there are few methods for measuring in-plane oxygen diffusion coefficients, which are important parameters for simulating oxygen flux distribution in gas diffusion layers (GDLs). In this study, we establish measurement methods and calculations for both in-plane and through-plane oxygen diffusion coefficients. Using in-house designed cells, we measure the in-plane and through-plane oxygen apparent diffusion coefficients of a commercial carbon paper (AvCarb EP40) at various torques and gas flow rates. We also simulate oxygen flux distributions in the GDL under each torque and gas flow rate. Our results show that the channel part is the major contributor to total oxygen flux at high torque conditions and that an increase in torque leads to a decrease in the contribution from the land part. Simulation results also suggest that a higher gas flow rate and lower torque contribute to a more uniform distribution of oxygen flux in the GDL.
Aerodynamic load analyses of less-emission HTS maglev train in evacuated tube transport system

An evacuated tube transport (ETT) system is proposed by combining evacuated tube technology and high temperature superconducting (HTS) maglev technology in this paper. It can be predicted that this future transport mode can own the advantages of less emission, low noise, high efficiency, and suitable for high-speed or super-high-speed application. The train running at a high speed will inevitably cause complex aerodynamic load behaviors in an enclosed low-pressure tube. It further affects the real energy consumption and the fatigue life of the components. In order to explore how the aerodynamic load behaves in an ETT-HTS Maglev system, we established a three-dimension numerical calculation model based on ANSYS FLUENT software. The steady aerodynamic loads on the train’s surface and the tube’s inner surface are investigated under different pressures and different operation speeds. It is found that the aerodynamic load on the surface of the train and tube is significantly affected by the pressure inside the tube and the running speed of the train. The aerodynamic load fluctuations at the rear of the train are relatively more violent than those at the head. We also found that the impact of compression wave and expansion wave on aerodynamic loads at different positions of the tube is related to the size of the flow field space between the tube and the train. These results can provide some reference for the less-emission train body design and the whole ETT-HTS Maglev system structural strength in the near future.
How is it effective for farmers to adopt environmentally friendly cultivated land protection technology: a configurational perspective

The adoption of environmentally friendly farmland conservation techniques by farmers is an important way to effectively curb agricultural surface pollution and promote the conservation of farmland quality. Based on 425 farmers’ in-depth interview data, a fuzzy-set qualitative comparative analysis method was used to construct a psychological cognition (farmers’ awareness and willingness to participate)—external context (organizational linkages and government regulation)—behavioral effect model to reveal the conditional configuration and multivariate paths of psychological cognition and external contextual factors influencing farmers’ behavioral effects on the adoption of environmentally friendly farmland conservation technologies. The results show that individual behavioral decision factors do not influence the behavioral effects of farmers. The results show that individual behavioral decision factors are not necessary to drive the effective adoption of environmentally friendly farmland conservation technologies and that multiple decision factors interact to form three sets of configurations that enhance the behavioral effectiveness of farmers, summarized as the willingness-to-participate dominant model, the internal and external constraints dominant model, and the external context dominant model.
Urban areas in rural landscapes – the importance of green space and local architecture for bat conservation

Published: June 2023

Urbanization is a highly disperse process, resulting in urban sprawl across landscapes. Within such landscapes, structural heterogeneity may be an important factor for maintaining biodiversity. We investigated the importance of habitat heterogeneity on bats in villages across the Schwäbische Alb, Germany, a progressively urbanized region. Bat activity and diversity were assessed using acoustic monitoring. We characterized habitat composition at the local and neighborhood scale and assessed environmental characteristics of urban density, vegetation cover and architectural features, combining satellite and ground-based measures. Our results revealed that the extent of urban areas determines the occurrence of different bat species, while local spatial, structural, and architectonic parameters at recording sites affected bat activity, feeding activity and social encounters. Larger urban areas with increased proportion of impervious surfaces and newly constructed housing areas were associated with fewer bat species and lower bat activity. Bat activity and feeding were highest in housing areas constructed between 1950-2000 and increased with higher proportions of older, rather openly structured vegetation. Our results clearly show a combined importance of environmental parameters across spatial scales, affecting habitat suitability and quality of rural urban areas for bats. This highlights that strategies for biodiversity inclusion in rural urban planning need to consider both local and neighborhood conditions to support bat diversity and vital bat activity. In particular, it exemplifies future challenges to maintain biodiversity within progressively urbanized rural landscapes, as this needs support by municipalities for maintaining space for nature in areas designated for urban development and also the consciousness by local residents for biodiversity-friendly modernizations.
