Authors:   Research Institute of Science Education, Jo Jae Seong
Published: August 2023

This study explored the case of elementary school A, which actually operates e-portfolio evaluation, in order to explore the evaluative meaning of classes using e-portfolio in elementary school. Specifically, the following research results were obtained by analyzing qualitative data by applying participatory observation, in-depth interview, and document analysis methods from March 2019 to April 2021. First, the e-portfolio had the meaning of evaluation that could confirm the learning process as a whole. It was confirmed that it comprehensively records how the project begins and ends. Second, the e-portfolio was an evaluation technique that revealed students’ unique individuality and values. The content and format of the students’ class results were uniquely changed for each individual. Third, the e-portfolio was functioning as an evaluation criterion that showed whether the class was faithful. Based on the successful evaluation case of elementary school A, research cases at various levels are discovered, and follow-up studies are also needed to examine the influence of e-portfolio classes in particular. It is expected that theoretical and practical follow-up studies using the basic implications of this study will proceed.

Authors:   Research Institute of Science Education, Kim Daehee , Lee Jungwoo , Ji Youngrae , Park Eunjeong
Published: August 2023

Due to the recent trend of the decreasing number of students and over-growing teacher education programs, the Ministry of Education has been pushing for a change in the role of the teacher training process. As a result, the Graduate School of Education is trying to convert it to a system fostering the capabilities of existing teachers rather than training new teachers. In the school context, teachers are required to play a variety of roles, such as cultivating career and digital literacy, because of the demand for convergence curriculum guidance and non-face-to-face classes. The consequence has also resulted from consumer-tailored education, the free grade system, the development of information and communication technology, the impact of COVID-19. The Graduate School of Education at Sunchon National University must come up with a drastic development plan by reflecting the results of the previous five-cycle evaluation of teacher education institutions and providing educational services that can strengthen educational capabilities of teachers in schools in the Jeollanam-do region. In order to make it concrete, we conducted an analysis of the results of the five-cycle evaluation of teacher training institutions, an analysis of the reform plan for the teacher training course from the Ministry of Education, a survey of opinions of the professors in the Graduate School of Education, Sunchon National University, and a survey of opinions of the graduate students of education and teachers in the Jeollanam-do region. As a result of the study, the Graduate School of Education at Sunchon National University firstly divided the majors into the teacher education courses for pre-service teachers and professional development for in-service teachers based on the cutbacks in the Graduate School of Education. Second, we encouraged all departments to improve the content and methods of teaching and learning in the Graduate School of Education at Sunchon National University so that teachers and graduate students can develop their teaching skills and abilities in the future. Third, it is necessary to offer integrative majors, which are expected to be in high demand in the future. This will bring about strengthening the competency of pre-service teachers and advancing the graduate school of education.
Fourth, newly-coming graduate students should be welcome through specialized doctoral degree (i.e., Doctor of Education or Ed.D.) programs in the Graduate School of Education at Sunchon National University. Lastly, it is imperative to develop professional development courses for in-service teachers to acquire first-grade teacher qualifications at the Graduate School of Education and to cultivate competency of teaching and learning.

Authors:   Research Institute of Science Education, Jun Youngcook , Park Hun
Published: August 2023

The purpose of this study is to improve the quality of non-face-to-face classes by introducing cases of non-face-to-face online calculus classes for college students and calculus classes for high school students. To this end, we collected data such as texts, videos, and student outcomes related to online math classes conducted over 2020 and 2021 for analyis and interpretation as part of a case study.
As a result, the discrete mathematics lectures for university students were mainly conducted as real-time video classes, showing the characteristics of using C and Mathematica programming tools in order to cultivate the ability to solve problems by performing tasks and demonstrating presentations. The calculus class for 3rd grade high school students adopted a mixed form of providing real-time video classes using Google Meet and OBS Studio. The high school teacher mostly dealt with problem-solving step-by-step explanations to prepare for college entrance exams, and provided video recordings of blackboard classes as a supplementary. By comparing and examining the two class cases, we identified several stumbling blocks that would be resolved and suggested future direction for improving the upcoming online math classes.

Authors:   Research Institute of Science Education, Kim Hwa-seong , Kim Jin-suk , Kang Ju Hyun , Ko Hee-Yoon
Published: August 2023

The purpose of this study is to develop a program suitable for specialized high school students by operating an entrepreneurship education program to enhance the creativity of specialized high school students using the metaverse. In this study, research data were collected through the participation observation, interviews with students, FGI, and questionnaires. The learners who participated in the Entrepreneurship Education Program responded that they did not know why they had to study Entrepreneurship. However, the learners acquired new concepts and information each time the session progressed, and each team was able to come up with an idea to solve the problem in a creative way and implement a solution on the metaverse. In the process of implementing solutions after discovering problems, the method of using the metaverse provided an opportunity to understand the entrepreneurship program. Learners responded that it was difficult for the class to understand the concept of Entrepreneurship, but they recognized the whole program positively and said that participating in this class would help them in their social life. However, in the course of this research, it was judged that there is a need to develop and supplement teaching and learning methods that allow students of specialized high schools to understand entrepreneurship more easily. To do so, it is necessary to seek teaching methods based on an in-depth understanding of the school culture of specialized high schools and methods of rapport formation.

Authors:   Research Institute of Science Education, Kim Dong-Ryeul
Published: August 2023

This study aimed to comprehend the conceptual structure and understanding of diffusion in science-gifted elementary school students. Thus, word association test, drawing test and conceptual understanding test were conducted on 80 gifted elementary school students in the six grade, who belonged to a gifted education center of university of education. When extracting key words from sentences they wrote on diffusion, this study confirmed 99 words, out of which, ‘Spread’, ‘Substance’ and ‘Movement’ appeared high in frequency. When visualized through semantic network, ‘Spread’ was positioned in the center, connecting with ‘Substance’ most. When analyzing their drawings of diffusion, this study found Level 3 most in frequency, which indicates an incomplete drawing with misconception included. Especially, in the drawings with misconception included, some often expressed that molecules partially moved in a state of balance not being sustained, or diffusion took place only in living organism, and others even understood diffusion as dispersion of light or visual field. When analyzing their conceptual structure of diffusion, this study discovered many of them had incomplete concepts including various misconceptions. The concept of diffusion is one of the main concepts that help students understand biological phenomena, and to have the exact concept of diffusion, students should understand other science concepts, such as dissolution, solubility and molecular motion. Therefore, it is necessary to develop additional programs and help them learn more effectively in classes for the gifted.

Indoxyl sulfate induces apoptotic cell death by inhibiting glycolysis in human astrocytes
Authors: Jeong Seung-Hyun , Park Samel , Choi Jae-sung , Cho Nam-Jun , Moon Jong-Seok , Gil Hyo-Wook
Published: August 2023

Background: Neurologic complications, such as cognitive and emotional dysfunction, have frequently been observed in chronic kidney disease (CKD) patients. Previous research shows that uremic toxins play a role in the pathogenesis of CKD-associated cognitive impairment. Since astrocytes contribute to the protection and survival of neurons, astrocyte function and brain metabolism may contribute to the pathogenesis of neurodegeneration. Indoxyl sulfate (IS) is the most popular uremic toxin. However, how IS-induced astrocyte injury brings about neurologic complications in CKD patients has not been elucidated. Methods: The rate of extracellular acidification was measured in astrocytes when IS (0.5–3 mM, 4 or 7 days) treatment was applied. The hexokinase 1 (HK1), pyruvate kinase isozyme M2 (PKM2), pyruvate dehydrogenase (PDH), and phosphofructokinase (PFKP) protein levels were also measured. The activation of the apoptotic pathway was investigated using a confocal microscope, fluorescence- activated cell sorting, and cell three-dimensional imaging was used. Results: In astrocytes, IS affected glycolysis in not only dose-dependently but also time-dependently. Additionally, HK1, PKM2, PDH, and PFKP levels were decreased in IS-treated group when compared to the control. The results were prominent in cases with higher doses and longer exposure duration. The apoptotic features after IS treatment were also observed. Conclusion: Our results showed that the inhibition of glycolysis by IS in astrocytes leads to cell death via apoptosis. Specifically, longterm and higher-dose exposures had more serious effects on astrocytes. Our results suggest that the glycolysis pathway and related targets could provide a novel approach to cognitive dysfunction in CKD patients.

"Malaysian music was influenced by British, Portuguese, Indian, and Chinese cultures, which created syncretic music. Aesthetics values strengthen the existence of syncretic music by molding taste and interest among the listeners. It somehow creates various feelings whether to appreciate, accept, or against the music, further developing musical preferences among individuals. Exploring aesthetic values in popular and traditional music is crucial as many cultures have influenced Malaysia due to colonization, trading, wedding, and migration. This paper reviews on Malaysian syncretic music, the aesthetic values in Malaysian popular and traditional music, and the influence factors of Malaysian music. It is found that there was a confluence of various intercultural musical elements in the early era, while assimilation has taken place due to traditional Malay rhythmic patterns and traditional folk themes. This led to the Malaysian conception of music and musical composition, creating the idea that Malaysian music has drastically expanded its artistic resources since the pre-colonial era. We also found communities living in the pre-modern or modern era have different unique taste in the aesthetic characteristics. Despite this, most remote communities are compelled to participate in postmodernity in some way due to the globalization of media, capital, and mobile networks. These combinations result in many theories, concepts, and discourses that enrich aesthetic values in Malaysian syncretic music. Keywords: Syncretic music, culture, Malaysian music, aesthetic, music assimilation, traditional music"

Published: August 2023

"The problematic field of the article focuses on aspects of genre and style transformation of well-known musical content that is recognizable and stylistically significant. In contemporary non-academic art, the established semantics of the original source is subject to change under the influence of a new creative rethinking, the possibilities of which are only increasing in the context of the technologies of the twenty-first century. These possibilities are embodied in various visual formats: from direct citation to borrowing or processing with its variations. The relevance of this topic lies in the need to study the phenomenon of citation as such, as well as to research and systematize other means of genre and style transformation of musical material. The direct object of the study is mostly music of the so-called “light” genres, music of mass culture, due to more mobile, transparent and visual observation opportunities. The author offers a self-made classification of possible methods of borrowing someone else’s text as a means of compositional technique, as well as of individual genres: cover, remake, borrowing, allusion, sampling. In the context of the study of the phenomenon of “musical text”, the peculiarities of realization and perception of the artistic and integral result are traced. As a result, several types of citation that have become widespread in contemporary music are distinguished. Keywords: quote, citation, borrowing, autocitation, samples, cover, remake, collage, intertextuality. "

"The future belongs to those who will never stop learning - this is a very modern mindset. Learning is a lifelong habit. It is a process, a work in progress for a lifetime. This process can have many stages and I want to explore them in this article, because becoming aware of them we can improve our knowledge and our benefits from learning. This information can be useful in pedagogy but also in the self-control of professionals, because this article is regarding the professional singer’s development, focusing on the breathing technique in singing. The society we live in is an extremely dynamic one, changes are happening faster and faster, and knowledge is a must, a continuous process that does not stop with the completion of studies. Discovering one’s own ignorance can be the start of progress. The most modern learning process admits and embraces the dynamic between learning, unlearning, and relearning - at whatever professional stage we are. The present article is not intended to be a new breathing technique proposal, nor an exposition or a debate of the multiple existing breathing techniques... but to state the main objectives of the optimal breathing of a professional singer and the possible defects that must be corrected. The focus of this article is the availability of learning, experimentation and permanent discovery of one’s own body and mind - corelating them with the functionality of the technique, under the guidance of a teacher or in the individual study of each singer - in short, an invitation to make the rehearsals much more flexibles.

Efficiency and Optimal size of Italian Public Hospitals: Results from Data Envelopment Analysis
Authors: Giancotti Monica , Rotundo Giorgia , Pipitone Vito , Mauro Marianna
Published: August 2023

Background: One of the major issues discussed in the literature about hospital efficiency is the impact of hospital size on technical efficiency. Many studies have observed that in some cases, hospital technical inefficiency is correlated with an incorrect size. This paper addresses this topic. In particular, we attempt to identify an optimal size of hospitals in terms of beds.

Methods: The study is organized as follow: first, we performed the Data Envelopment Analysis in order to calculate the technical and scale efficiency scores for a sample of 41 Italian public hospitals during the period 2010-2013; second, we investigated the impact of size on hospital efficiency, identifying the magnitudes of input reductions needed to make inefficient public hospitals efficient. Finally, we calculated the most productive scale size for each hospital in the sample. According to these results, through an overall observation, we attempted to identify an optimal size for hospitals in terms of beds.

Results: Most of the hospitals were inefficient and most of the inefficiency was the results of the presence of waste in terms of input resources. During the period considered, we found that inputs could be reduced by 22% on average. Economies of scale were found around 200 beds for 20.000 discharges per year.

Conclusions: The identification of an optimal size of hospitals in terms of beds still requires further efforts in the literature. However, this study contributes to support hospital managers in resource allocation choices through a quantitative approach.
Veterinarians are reluctant to recommend virtual consultations to a fellow veterinarian
Authors: Sigesmund Debbie , Coe Jason B. , Khosa Deep , Moore Irene C.
Published: August 2023

OBJECTIVE

To explore veterinarians’ use of virtual veterinarian-client-patient consultations before and during the coronavirus disease 2019 (COVID-19) pandemic and examine veterinarians’ attitudes toward virtual consultations.

SAMPLE

135 companion animal veterinarians in Canada, the US, and Europe.

METHODS

An anonymous online survey was distributed to gather participating veterinarians’ use of information and communication technologies and their perception of virtual consultations’ effect on patient care, client communication, and their own well-being. Willingness to recommend virtual consultations was evaluated using the Net Promoter Score. Multivariable logistic regression explored factors associated with willingness to recommend virtual consultations.

RESULTS

Percentage of participating veterinarians using the telephone and videoconferencing increased significantly (P < .001) from before (83.6% and 3.0%, respectively) to during the COVID-19 pandemic (97.0% and 22.4%, respectively). Participants were significantly less confident (P < .001) about their ability to reach a diagnosis using a virtual consultation as compared to a hands-on patient examination. Participants perceived client communication to be more challenging during virtual as compared to face-to-face consultations, particularly for building rapport and expressing empathy. Participants were extremely unwilling to recommend virtual consultations (Net Promoter Score = –41.4) with 21.6% (24/111) promoters and 63.1% (70/111) detractors. Confidence doing a virtual patient examination and comfort using videoconferencing technology were both positively associated (P < .05) with willingness to recommend virtual consultations.

CLINICAL RELEVANCE

Veterinary practices and organizations interested in encouraging virtual veterinarian-client-patient consultations likely need to prioritize veterinarians’ acceptance as an initial focus. The veterinary profession would benefit from further research and education to inform virtual veterinary care.
Computed tomographic features and surgical treatment of equine mandibular aneurysmal bone cysts with β-tricalcium phosphate in a multicenter case series
Authors: Spoormakers Tijn J. , Heim Corsin , Vermunt Lian , Fürst Anton , Rovel Tibor
Published: August 2023

OBJECTIVE

To describe clinical and imaging features and surgical treatment of equine mandibular aneurysmal bone cysts (ABCs) with β-tricalcium phosphate (TCP).

ANIMALS

3 horses (cases 1, 2, and 3) and 1 pony (case 4) with histologically confirmed ABC.

CLINICAL PRESENTATION

All cases had mandibular swelling with intact adjacent skin. Cases 1 to 3 had a body condition score of 3/5 and case 4 had 2/5 and showed quidding during mastication and, at oral examination, large interdental spaces and loose elements adjacent to the swelling. Radiography or CT was performed in all cases. In cases 1, 3, and 4, an expansile septate cystic space-occupying lesion with mass effect on the adjacent cortices and teeth was seen without compact bone destruction. Case 2 showed a heterogeneous osteolytic mass with multifocal cortical lysis and interruption. Case 4 had severe dental abnormalities of deciduous and precursors of permanent teeth. ABCs were surgically treated and filled with only TCP (case 3) or in combination with autologous bone marrow (cases 1, 2, and 4).

RESULTS

Cases 1 through 3 showed an uneventful reduction in ABC size with increased opacity/attenuation. In case 4, a surgical site infection occurred. After removal of TCP remnants, the ABC healed satisfactorily, but remaining dental abnormalities necessitated dietary adjustments to maintain an acceptable body condition score.

CLINICAL RELEVANCE

Treatment of ABCs with TCP had a favorable outcome and good long-term prognosis. In young specimens, the expansile effect on the development and eruption of neighboring teeth can influence and determine final functionality of the diseased dental quadrant.

METHODS

A retrospective study was performed evaluating dogs younger than 3 years old diagnosed with primary lower lid entropion between 2010 and 2020. Recurrence of entropion following temporary tacking sutures was evaluated. Surgical outcomes were evaluated of entropion surgery in dogs < and > 1 year of age.

RESULTS

44 dogs with entropion (71 eyes) had a temporary tacking procedure. The entropion resolved in 36.6% of eyes, requiring no further therapy. The median age of dogs successfully treated with a temporary tacking procedure was younger than those that failed. Forty-seven dogs (75 eyes) had entropion surgery at maturity, and 52 dogs (79 eyes) were juvenile. Twenty-seven dogs had temporary tacking procedure prior to surgery, accounting for the difference in number. There was no statistically significant difference in the recurrence rate of entropion between eyes of adult (6/75 [8%]) and juvenile dogs (10/79 [12.7%]) following surgery.

CLINICAL RELEVANCE

Entropion surgery in juvenile dogs is not associated with a higher risk of recurrence and need not be delayed until dogs are older than 1 year of age.

The aim of the study was to examine the genotype-allele determination of CYP1A2 rs2069514 and rs762551 polymorphisms in patients with mild and severe COVID-19 and to determine their effectiveness as prognostic criteria in COVID-19. The study consists of 60 patients who were hospitalized in intensive care or outpatient treatment due to COVID-19 in Istanbul NP Brain Hospital between 2020–2021. Genotyping was conducted by Real-Time PCR. Age (p<0.001); chronic disease (p=0.002); cardiovascular disease (p=0.004); respiratory distress (p<0.001); neurological disease (p=0.004); fatigue (p=0.048); loss of taste and smell (p=0.003); nausea/vomiting (p=0.026); intubated (p<0.001); ground glass image (p<0.001) and CYP1A2 genotypes (p<0.001) showed a statistically significant difference between patients with and without intensive care admission. According to multivariate logistic regression analysis, CYP1A2 *1A/*1C + *1C/*1C genotypes (OR:5.23 95% CI: 1.22–22.36; p=0.025), chronic disease (OR:4.68 95% CI:1.14–19.15; p=0.032) or patients at 65 years or older (OR:5.17, 95%CI:1.26–21.14; p=0.022) increased the risk of admission to the intensive care unit. According to our results, we strongly suggest considering the CYP1A2 rs2069514 and rs762551 polymorphisms as important predictors of Intensive Care Unit admission in patients with COVID-19, and we also suggest that genotype results will guide clinicians for the benefit and the efficiency of the treatment.
Entrepreneurial Learning in Higher Education: Perceptions, Realities and Collaborative Work from the Stakeholder Point of View

Published: August 2023

In recent years, Portuguese universities have diversified their strategies for the promotion of entrepreneurial education among (under/post) graduates, both through formal education and non- formal and informal activities. Indeed, Higher Education Institutions can provide entrepreneurial learning opportunities for students, stimulating new attitudes and behaviours towards entrepreneurship. In terms of non-formal and informal learning, various types of activity are of particular significance, and include entrepreneurship promotion and skills-based training, as well as monitoring of the development of ideas and projects. These activities are undertaken by various higher education stakeholders and key-actors, who contribute to the construction of an entrepreneurial ecosystem, and increase entrepreneurial spirit in (under/post) graduates. The research reported here is based on the main findings gathered from the ongoing project “Entrepreneurial Learning, Cooperation and the Labour Market: Good Practices in Higher Education (POAT-FSE)”, focusing particularly on the results of a survey questionnaire completed by a diverse sample of entities linked to Portuguese public Higher Education Institutions (HEIs) and working to promote non-formal and informal entrepreneurial activities, as well as a set of case studies carried out regarding examples of best practice in Portuguese Higher Education. In doing so, this paper aims to highlight the importance of non-formal and informal learning, and to contribute to reflection on the added value of inter-organizational cooperation and collaborative work.

Designing, changing and adapting organizations to secure viability is challenging for companies. Researchers often fail to holistically design or transform organizations. Thus, the aim of this study is to propose a holistic approach how organizations can be designed, changed or managed considering also its implications to production management following lean management principles. Hereby the Viable System Model was applied. This structure can be applied to any kind of structured organization and for its management with goals to be achieved in modern society; however focus of the research is the cluster of manufacturing and assembly companies. Goal of the developed organizational model is to be able to react to all potential company environments by taking decisions regarding organization and production management functions correctly and in the right moment based on the needed information. To ensure this, standardized communication channels were defined. In conclusion this proposed approach enables companies to have internal mechanisms to secure viability and also in production to reduce necessary stocks, lead times, manpower allocation and leads to an increase of the service level to the final customer.
Effectiveness of Active Confinement Techniques with Steel Ribbons: Masonry Buildings
Authors: Ferretti Elena
Published: August 2023

In the present paper, we analyzed the main advantages of the active confinement techniques with a particular focus on the CAM system, which is an Italian reinforcement technique with pre-tensioned stainless-steel ribbons. Italian seismic codes classify the CAM system as belonging to the strengthening category of “horizontal and vertical ties”. Therefore, we compared the CAM system to the reinforcement techniques with horizontal and vertical ties in order to understand the actual similarities and possible differences between them. Moreover, we offered a deep analysis of the main critical issues of the CAM system, distinguishing between geometrical and mechanical weak-points. In particular, we analyzed the strengthening mechanism of the CAM system, still poorly understood, by performing a static analysis in the Mohr/Coulomb plane. Finally, we provided suggestions for future developments.
Decision Support Opportunities in the Green Supply Chain Coordination

Published: August 2023

In the 21st century, major changes have taken place in supply chain management. First of all, some new type of supply chains has appeared beside the traditional supply chains. The growing level of pollution, the decreasing level of non-renewable sources indicate changes in the business life. Companies find some alternate solutions to protect the environment – use renewable sources, integrate recycling processes, use the inverse logistics etc. So companies are getting to be eco-conscious, we are called them as ‘green companies’. If these green companies are in one supply chain, we are called as ‘green supply chain’. The coordination of supply chains – whether if traditional or green– is one of the most important research topics in this century. The number of chain members is growing; the cooperation is getting to be more difficult. That is why contracts could be a good solution for this problem, because they define a framework for the parties to manage their relationships. Contracts work well, if the right type is chosen according to the nature of the relationship. But in the case of a green supply chain, there are other influencing factors. Green companies are able to accept higher prices to get higher quality products. In the paper, we analyse how these factors influence the decision-makers to choose between the contracts; we use the AHP decision-making method.
