Post-lifelong learning and the ontology of learning
Authors:   The Korean Society for Lifelong Education, Choi Kunjung , Han Soonghee
Published: October 2024

In the various arguments that talk about the future of education, the six principles platform of the suburban education frame, which is still operating in the way of defining the learning style, is 'who, what, how, when, what, why' learning. It is expressed that the person can use it for the purpose of the indigenous people, is separated in time and space, and the object and method can be unique. The lifelong learning approach that can use concepts such as bearing environment learning, transformative learning, situated learning, and expanded learning is included in the scope of application from the moment of expanding the horizon of learning, and more new approaches are possible. In the view of researchers, it is necessary to understand from an independent and neutral perspective. Researchers attempt the generative ability of learning, that is, the '(object)-becoming' of learning, and unravel the new existential members of learning with Latour's owner network theory (ANT) and Gaia theory, which inherited Deleuze's assemblage theory. Through this, they try to refresh the image of “future lifelong education” through lifelong learning. The researchers argue that early lifelong education is futuristic, and what the 'abstract machine' is, and how it differs from the current fitness university signal configuration. Second, they analyze the future educational discourse being discused in the future into several turning points, and judge whether the ontological way of understanding learners will not deviate from the state university interpretation method despite the “future discussion” within it. Finally, the researchers introduce the post-lifelong learning perspective as a new way to replace it, and suggest methods and conditions that can define the existence and function of 'eco-global' learning.

Authors:   The Korean Society for Lifelong Education, Cho Sungbum , Jang Chang Sung , Bae Sanghoon
Published: October 2024

The purpose of this study is to identify types of perceived institutional support among adult learners at four-year universities in Korea and to investigate how predictors and outcomes of institutional support vary across different groups. A latent profile analysis was employed to analyze data of 465 adult learners, sourced from the Korea-National Survey of Student Engagement surveyed in 2023. The main findings are as follows. First, four distinct types of perceived institutional support were identified: (a) unsatisfactory and avoidance, (b) ordinary and casual, (c) satisfactory and engagement, and (d) relationship-oriented. Second, significant factors differentiating the latent profile membership probabilities included grade, university admission type, type of high school, collaborative behavior, academic self-efficacy, and career maturity. Lastly, institutional commitment, as an outcome of university experience, was found to be higher in the ‘satisfactory and engagement’ group compared to others. Based on the findings, we discussed academic and practical implications for building adult-friendly university support systems that enrich adult learners’ student engagement and institutional commitment.

Authors:   The Korean Society for Lifelong Education, Lee Kyoungyang
Published: October 2024

The purpose of this research is to understand the status of adult literacy teacher training through the experience of participating in adult literacy education teacher training for academic accreditation, and to find ways to successfully operate literacy teacher training. To this end, this qualitative study was conducted on the experiences and perceptions of four pre-service teacher participants who took part in the literacy education teacher training program at the institute for Lifelong Education. The collected qualitative research data were analyzed using MAXQDA 2020. As a result of the analysis, first, it was found that pre-service literacy teachers participate in the literacy training program with various motives, and are “curious” about the actual field stories of literacy education and the experiences of literacy teachers. Second, it was found that pre-service literacy teachers recognized the literacy education training program as “non-systemetic” and wanted to have an opportunity to do microteaching. Third, after completing the literacy teacher training program, the pre-service teachers recognized the treatment of literacy education teachers and field of literacy education as “ambiguous” and suggested literacy training contents to be added to the literacy teacher training program. Based on these research results, improvements were discussed to improve the quality of literacy education teacher training program.
IoT-Based Framework for Implementation of Leaf Color Chart for Nitrogen Monitoring in Crop
Authors: Nitin Padariya
Published: October 2024

Effective nitrogen management is essential in precision agriculture to optimize crop yields and promote environmental sustainability. Conventional techniques for evaluating nitrogen levels, although commonly used, suffer from a lack of accuracy and scalability. This research presents a novel design framework that combines the Leaf Colour Chart (LCC), a well-established agricultural tool for nitrogen evaluation, with modern Internet of Things (IoT) technologies. The proposed system utilizes specialized sensors to gather precise leaf color data, which is subsequently analyzed using cloud-based computer vision techniques to correctly and instantaneously predict nitrogen levels. The framework streamlines data gathering and processing, allowing for accurate nitrogen management. This enables the application of fertilizer to specific areas and minimizes wastage. This article provides an overview of the system architecture, examines the difficulties and resolutions in integrating Internet of Things (IoT) technology in agriculture, and showcases case studies that demonstrate the effectiveness of the framework in practical environments. The incorporation of IoT technology with the Leaf Colour Chart signifies a notable progression in agricultural technology, offering the potential to enhance crop management techniques and support sustainable agriculture endeavors.

Citation Cartels: Understanding Their Emergence and Impact on the Academic World
Authors: Willie Michael Mncedisi
Published: October 2024

Citation metrics have become pivotal in evaluating academic research and influencing funding, promotions, and institutional prestige. However, the increasing emphasis on these metrics has given rise to unethical practices, notably citation cartels, which artificially inflate citation counts through collusive agreements among researchers or journals. This study investigates the prevalence and impact of citation cartels by analysing citation patterns in recent papers. Using a systematic approach, we examined citation data across five papers to identify patterns of collusion and the extent of citation inflation. The results reveal that Author 1 was cited in every reference across four out of five papers, either as a sole author or co-author, with a direct or indirect responsibility for 100% of the citations. Similarly, Authors 2 and 3 demonstrated substantial influence, with median citation shares of 36% and 35%, respectively. These findings highlight the significant role of key authors in shaping citation distributions and raise concerns about the integrity of citation metrics. The study concludes with recommendations for addressing citation cartels, including implementing detection systems, enhanced peer review processes, and a more balanced approach to evaluating research impact.

Cohort study on the treatment of BRAF V600E mutant metastatic colorectal cancer with integrated Chinese and western medicine
Authors: Bian Jiang-Yu , Feng Yu-Fang , He Wen-Ting , Zhang Tong
Published: October 2024

BACKGROUND

Patients with BRAF V600E mutant metastatic colorectal cancer (mCRC) have a low incidence rate, poor biological activity, suboptimal response to conventional treatments, and a poor prognosis. In the previous cohort study on mCRC conducted by our team, it was observed that integrated Chinese and Western medicine treatment could significantly prolong the overall survival (OS) of patients with colorectal cancer. Therefore, we further explored the survival benefits in the population with BRAF V600E mutant mCRC.

AIM

To evaluate the efficacy of integrated Chinese and Western medicine in the treatment of BRAF V600E mutant metastatic colorectal cancer.

METHODS

A cohort study was conducted on patients with BRAF V600E mutant metastatic colorectal cancer admitted to Xiyuan Hospital of China Academy of Chinese Medical Sciences and Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from January 2016 to December 2022. The patients were divided into two cohorts.

RESULTS

A total of 34 cases were included, with 23 in Chinese-Western medicine cohort (cohort A) and 11 in Western medicine cohort (cohort B). The median overall survival was 19.9 months in cohort A and 14.2 months in cohort B, with a statistically significant difference (P = 0.038, hazard ratio = 0.46). The 1-3-year survival rates were 95.65% (22/23), 39.13% (9/23), and 26.09% (6/23) in cohort A, and 63.64% (7/11), 18.18% (2/11), and 9.09% (1/11) in cohort B, respectively. Subgroup analysis showed statistically significant differences in median OS between the two cohorts in the right colon, liver metastasis, chemotherapy, and first-line treatment subgroups (P < 0.05).

CONCLUSION

Integrated Chinese and Western medicine can prolong the survival and reduce the risk of death in patients with BRAF V600E mutant metastatic colorectal cancer, with more pronounced benefits observed in patients with right colon involvement, liver metastasis, combined chemotherapy, and first-line treatment.
Extramedullary plasmacytoma with the uvula as first affected site: A case report
Authors: Yang Jing , Peng Hui , Tu Sheng-Ke , Li Min , Song Kui
Published: October 2024

BACKGROUND

Extramedullary plasmacytoma (EMP) represents one of the rarer forms of plasma cell malignancies, capable of impacting a variety of tissues and organs throughout the body. The majority of EMP cases are predominantly found in the head and neck region, especially within the laryngopharynx, as well as in the gastrointestinal tract. While there have been documented instances of oropharyngeal involvement in EMP cases in the academic literature, it is important to note that EMP specifically affecting the uvula is exceedingly uncommon. Furthermore, it is noteworthy that over 60% of epithelial carcinomas in the upper respiratory tract and oropharynx tend to metastasize to the cervical lymph nodes, indicating a propensity for regional spread in these types of cancers. In this context, we present a rare case of extramedullary plasmacytoma where the uvula served as the initially affected site. This case emphasizes the need for heightened awareness among clinicians regarding such unusual comorbidities, as early recognition and diagnosis can significantly influence patient management and treatment outcomes. In addition, a review of the relevant literature is included to further educate and inform healthcare professionals about this rare presentation, ultimately aiming to enhance clinical understanding and improve patient care in similar situations.

CASE SUMMARY

A 51-year-old man was admitted to our hospital because of a slowly enlarging neck mass. A physical examination revealed a palpable left lymph node, and magnetic resonance imaging (MRI) of the oropharynx and the neck showed a soft tissue mass in the oropharynx and enlargement of multiple lymph nodes in the neck. The soft tissue mass was diagnosed as plasmacytoma by immunohistochemical analysis. Monoclonal immunoglobulins and bone marrow biopsy showed normal results. Therefore, we diagnosed that as EMP of the uvula. After four cycles of adjuvant chemotherapy dominated by bortezomib, MRI reexamination showed a significant reduction of the mass in the oropharynx and the cervical lymph nodes. Afterwards, the λ light chain returned to normal levels. There was no evidence of evolution to multiple myeloma.

CONCLUSION

We have reported a rare case of extramedullary plasmacytoma with the uvula as the first affected site and the relevant literature is reviewed to improve clinicians' awareness of such rare comorbidities.
Informal Inferential Reasoning on Simple Linear Regression Encouraging Critical Thinking
Authors: Bråtalien M. , Naalsund M.
Published: October 2024

Informal inferential reasoning (IIR), described as making evidence-based generalizations about a population based on samples, is considered important for the development of argumentation-, inference-, critical thinking - and aggregate thinking abilities. This article aims to explore how undergraduate students’ IIR can develop in an inquiry problem-solving session on simple linear regression, through individual think-aloud protocols with follow-up conversations with five students. Our findings suggest that enabling and supporting the students to grapple with their own hypotheses is important for their development of IIR encouraging critical thinking. From initial hypotheses with limited argumentation and little regard to the probabilistic nature of statistical inferences, the students’ reasoning evolved in terms of making probabilistic generalizations from data when they were given time and concurrent probing to elaborate on, and question, their own arguments and inferences. We also suggest that in addition to emphasize the signal in the noise, giving attention to the noise around the signal can be fruitful for their IIR.
On the relationship between students’ overall satisfaction with higher education STEM courses, and university teachers’ didactical practice. An empirical analysis
Authors: Abrahamsen E. , Husebø D. , Kvaløy J.T. , Alhourani A.
Published: October 2024

In this article, we discuss the relationship between students' overall satisfaction with higher education STEM courses (Science, Technology, Engineering, and Mathematics), and the teachers' didactical practice. We analyzed student feedback from 4,683 digital course evaluations which spanned the period from fall 2020 to fall 2021 at the Faculty of Science and Technology (TN-faculty), University of Stavanger (UiS). Additionally, we collected 1854 open-ended written responses in spring and fall 2022, and conducted two focus group interviews in spring 2023 with eight students from the same population. We raise the research questions: What is the connection between students´ overall satisfaction with STEM courses, found in an institutional student evaluation procedure at UiS, and the university teachers’ didactical practice? And what can we learn from students´ evaluations and feedback that is relevant to how we perceive and strive for teaching and educational quality enhancement in higher education? Our analysis shows that there are strong correlations between students´ overall satisfaction, the evaluation questions, and how they understand what being prepared for teaching means.
Stand-Up Comedy as an Erotic Art: Reframing Stand-Up Comic Performance Through the Lens of Audre Lorde
Authors: Gogerty Megan
Published: October 2024

Violent metaphors are common in the description of stand-up comedy. If a comedian is successful, she “kills”—vaudeville slang that hardened in the twentieth century into an aggressive, hierarchical ethos this article refers to as the dominance model that is problematic because it reproduces systems of oppression that disadvantage comedians of marginalized identities, especially women and LGBTQIA+ performers. While pervasive in the stand-up industry, the dominance model is not inherent to the art form itself but is rather a by-product of the white, heteropatriarchal culture in which stand-up was forged. A more inclusive model frames stand-up comedy as an erotic art as defined by Audre Lorde in “Uses of the Erotic.” Lorde argues that erotic knowledge is deeply felt in the body, joyful, and shared, a description that neatly encapsulates the experience of stand-up comedy for both performer and audience and offers a fresh, feminist approach to understanding stand-up comedy performance.
A population-level framework to estimate unequal exposure to indoor heat and air pollution

Published: October 2024

As people in the UK spend 95% of their time indoors, buildings are an important modifier of exposure to both non-optimal temperatures and air pollution. High ambient temperature and high PM2.5 (particulate matter) concentrations often occur together in urban areas. Residential building types prone to overheating (e.g. purpose-built flats) are often also more common in urban areas. Together, this may lead to spatial and demographic inequalities in indoor exposure to heat and PM2.5 from outdoor sources. By combining building simulations (EnergyPlus), a spatially distributed description of the residential building stock—from publicly available Energy Performance Certificate (EPC) data, ambient temperature, PM2.5 data and area-level (40–250 households) socio-demographic data—we estimated these inequalities in exposure for the population of England and Wales. Maximum indoor temperature was higher in areas with larger ethnic minority and infant populations, and lower in areas with a higher proportion of people aged ≥ 65 years. Indoor concentrations of outdoor-source PM2.5 were higher in areas with larger ethnic minority and low-income populations. With rising inequality in England and Wales, housing and environmental conditions play an important role in contributing to health inequalities from social disadvantage.
Policy relevance
Differences in environmental exposures may partly explain inequalities in health outcomes. These differences are mediated by dwelling type and quality. Identifying the driving factors for differences in environmental exposures may allow for the development of interventions to address health inequalities more effectively. This study finds differences in indoor exposure across socio-demographic groups due to both location and housing. This could be of interest to national, regional and local authorities responsible for targeting building retrofit interventions across the housing stock.

This paper explores the environmental impacts of retaining or replacing buildings by extending the consequential replacement framework (CRF) for life-cycle assessment (LCA) from individual buildings towards the urban scale. It addresses a gap in previous studies by examining the broader consequences of building-level retention or replacement decisions in the built environment, namely greenhouse gas (GHG) emissions from associated infrastructure construction. The case study, which is located in Finland, investigates alternative ways to densify a growing city, some of which can be achieved within the urban structure, while others require greenfield construction elsewhere in the city. The results reveal that refurbishing and extending already existing buildings is worthwhile in terms of GHG emissions, even if some of the additional floor area targeted in densification were to be built on a greenfield site. After 50 years, the accumulated GHG emissions of scenarios that develop existing buildings are 0.2–12% less than those from replacement scenarios, depending on whether the targeted densification is minor or major and the amount of infrastructure construction involved. This is primarily due to the 11–35% smaller upfront embodied GHG emissions of refurbishment compared with new construction—which 50 years do not offset.
Policy relevance
This paper reinforces the notion from previous research that developing the existing building stock holds major emission-savings potential, even more so than replacement with energy-efficient new build. It highlights the potential contribution of existing building stocks in low-emission city development, even in growing city contexts. The case study results challenge the common belief in urban planning that if replacement involves densification, it must be a more low-emission alternative than retention, and conversely, if retention leads to greenfield construction, it must be higher in emissions than replacement. Low-emission urban planning should base its conclusions on urban LCA. This paper introduces an infrastructure-extended CRF that accounts for building retention and replacement scenarios, ensuring methodological robustness. The approach is essential for policymakers to base their decisions on evidence and prioritise low-emission development alternatives. Which policymakers hold power over such decisions and which instruments are suitable to pursue these goals depend on the context.

Spor Kuruluşlarında Maliyet Yönetimi, Dengeli Puan Kartı Uygulaması ve Performans Ölçümü: Fitness Merkezi Örneği
Authors: Binici Fatih Ömür
Published: October 2024

Günümüzde artık spor kuruluşları spor faaliyetleri, rekreasyon, fitness veya serbest zaman etkinlikleri ve bu etkinliklerle ilgili ürün ve hizmetleri sunmaları açısından spor endüstrisinin önemli bir parçası olarak görülmektedir. Rekabetin yoğun olarak yaşandığı spor endüstrisinde bu kuruluşların sürdürülebilirliklerinin sağlanması, ticari işletmelerde olduğu gibi istikrarlı bir finansal alt yapı ile kaliteli bir organizasyonel süreç yapısına bağlıdır. Ancak müşterilerine çok sayıda farklı hizmet sunan spor kuruluşlarında, iş kararlarının alınmasında güvenilir temel oluşturacak ve rekabet avantajını koruyup sürdürecek doğru maliyetleme yöntemini seçmek önemli bir sorundur. Bu doğrultuda çalışmada, spor kuruluşları için ihtiyaca göre uyarlanabilen maliyetleme yöntemlerinden biri olan Faaliyet Tabanlı Maliyetleme (FTM) ile performans ölçümü için Dengeli Puan Kartı (DPK) perspektifi sunulmuştur. Bu bağlamda FTM ve DPK tasarımı ile uygulaması için spor endüstrisi içerisinde önemli bir paya sahip olan fitness merkezi seçilmiştir. Çalışmada nitel araştırma yöntemlerinden örnek olay tekniğinden yararlanılmıştır. Uygulamada Erzurum ilinde faaliyet gösteren tarafımızca seçilmiş bir fitness merkezinin FTM ve DPK yöntemi kullanılarak maliyetlerin ortaya çıkarılması ve performans ölçümünün gerçekleştirilmesi amaçlanmıştır. Veriler, Ocak-Mart 2024 döneminde şirketin idarecisi ve antrenör ile yapılan yüz yüze görüşmeler, ayrıca şirket tarafından paylaşılan belgelerin incelemesi yoluyla toplanmıştır. Bulgu ve değerlendirmeler neticesinde; spor kuruluşu olarak fitness merkezinin, sunduğu hizmetler ile çeşitliliği ve kaynak tüketiminin düşük olması nedeniyle maliyet yönetimi ve performans ölçümünde FTM ve DPK’ in başarılı bir şekilde uygulanabileceği belirlenmiştir. Bu çalışmada FTM ve DPK’ in fitness merkezinde uygulanabilirliğinin incelenmesi açısından alan yazına değer katacağı düşünülmektedir.
