A Comparative Study of Idiomatic Expressions Related to 'Eyes’ in Korean and Tamil.
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, K Esther R , Im Geon-su
Published: March 2024

Objectives The purpose of this study is to compare the idiomatic expressions related to ‘eyes’ in Korean and Tamil language and to categorize them based on their types. Also this study analyzes the learner's perception rate of Korean idiomatic expressions.
Methods First, we categorize and classify Korean and Tamil idioms into four distinct groups: expressions with similar meaning and structure, those with similar meanings but different structures, expressions with different meanings and structures, and idioms exclusive to the Korean language. Secondly, utilizing a Likert 5-point scale survey, we analyze the level of difficulty in identifying and comprehending Korean idiomatic expressions. The survey was conducted through Google Forms containing the list of 28 idiomatic expressions, and the responses from the 30 Tamil learners were compiled through SPSS.
Results The survey reveals that among all the eye-related idioms examined, the following expressions such as “to get soil in one's eyes”, “to get one's eyes covered with pea pods”, “to flip one's eyelid”, “to sell one eye”, and “to turn on the light in one's eyes”, have the highest mean values. Hence it reveals that they were the most challenging expressions for Tamil learners. Notably, idiomatic expressions unique to the Korean language emerge as particularly difficult for Tamil learners. Following that, factor analysis was conducted focusing on differences between language and culture.
Conclusions Based on these results, it was confirmed that the learner's mother tongue should be considered as an important factor, and this study intended to find implications for Tamil-speaking learners to more effectively understand and acquire Korean idiomatic expressions.

Published: March 2024

Currently, the Customer Service Unit (ULP) of the Blang Kejeren State Power Company (PLN) uses the system of the Diesel Power Power Centre (PLTD). Sistem ini terdiri dari PLTD yang dimiliki PLN dan PLtD Lewa, serta beberapa PLTMH (Pusat Listrik Tenaga Mikro Hidro). Aim of the study is to assess the technical viability of the 20 kV ULP Blangkejeren system if supplied with the Kutacane GI and parallel with Distributed Generation (DG). This is because there is no distribution network that can connect the Blangkejeren ULP load centre to the Kutacane GI. Using the PSS Sincal Power System Analysis Application, load scenarios for power plants and distribution networks are modeled and simulated. The findings indicate that the 20kV Ulp Blangkjeren system provided by GI Kutacana, PLTMH, PLTM Lawe, and PLTD Rema is the most appropriate scenario. This situation is regarded as optimal, with a network voltage of 21.07 kV on the ULP Blangkejeren Connection Guard Bus.

Published: March 2024

Multicultural cultural values are a strong foundation to be believed and important in the development of the world of Guidance and Counseling, especially in multicultural counseling practices. The cultural diversity that exists in Indonesia is very appropriate when counselors are able to explore and implement cultural values in counseling practices. One of the cultural values that can be used is to combine the concept of Balinese cultural values based on the beliefs of ancestors since ancient times which are religious through stories and meanings implied from generation to generation in the use of Tridatu thread bracelets and provide a special feel, especially for Hindus. The research method used is a qualitative description method by collecting library data, reading and recording and processing research materials then presenting them and drawing conclusions from the data obtained regarding the use of the Tridatu Bracelet. The thread used for Tridatu is not an ordinary thread. Before being given to the people, the thread has certainly gone through a ritual process first so that it has a deep meaning and philosophy. Hindus believe that the Tridatu Bracelet has the power of God Hyang Almighty as the creator, maintainer, and smelter. Counselors as implementers of counseling must really have an awareness of the cultural diversity that exists. Then the counselor should have good competence in multicultural coverage, namely awareness, knowledge and skills.

The Made in China 2025 strategy: Perceptions and reservations of China’s state capitalist economic model
Authors: Nawaz Farrukh , Abu Saleem Khalil , Kayani Umar
Published: March 2024

The Made in China 2025 (MIC 2025) strategy was introduced in 2015 and aims to reduce Chinese reliance on foreign technologies by adopting the import-substitution policy. The United States (US) considers China’s super-ambitious industrial policy as a serious threat and is concerned about its high-tech industries, especially as Chinese technological firms are receiving generous government subsidies and tax cuts. The US, thus, entered a direct trade war with China to protect its domestic industries from unfair and inequitable competition. The US-China trade war has seriously shifted and interrupted global supply chains, thus creating a situation of uncertainty and instability for businesses that import and export US and Chinese products. The article is policy-based, and we reviewed the existing literature in depth. We addressed the industrialization pursuits of China under the MIC 2025. Furthermore, the article has analyzed the impact of the US-China trade war on global supply chains. Finally, the article has many implications; the article provides the possible policy routes for the governments of developing countries and regulators to address the reservations of developed countries regarding state-sponsored industries.
Ethical systems’ dynamics in family business
Authors: Rahatullah Muhammad Khan
Published: March 2024

Building an ethical culture is challenging and it is a basic requirement for companies to embed transparency in their systems, creating a positive image and serving the internal and external communities. Twelve family-owned businesses participated in qualitative research. Interviews were conducted with employees of these businesses to explore the moral dynamics in their business. The paper significantly adds knowledge to the literature by exploring the role of ethics in particular contexts. It explores how these companies build the ethical culture, identifying the ethical culture sustainability triggers, challenges, and role of religion. Values, culture, community, and social norms are identified as major ingredients of sustainable principled culture development, and implementation of ethical policies and procedures require institutional and structural mechanisms for effectiveness in family-owned businesses. Numerous findings are in contrast to the literature, whereas, in other instances these are similar. Religion, society, family image, the entrepreneurs themselves, and their family members play a vital role. Non-interference in private matters of the employees, whistle-blowing, code of ethics, training and awareness creation, and a number of other factors play a leading role in ethical culture development in family businesses.
Revealing population demographics with environmental RNA
Authors: Hechler Robert , Cristescu Melania
Published: March 2024

The analysis of environmental DNA (eDNA) and environmental RNA (eRNA)
released by organisms into their surrounding environment (water, soil,
air), have emerged as powerful tools for biodiversity monitoring. While
eDNA has been widely adopted for the non-invasive detection of species
and characterization of community composition across the tree of life,
eRNA is in its infancy. Due to its functional nature, eRNA holds
intriguing potential for biodiversity monitoring opening new avenues of
research beyond species detection. For example, conspecifics that are
almost genetically identical can exhibit distinct transcriptomic
differences depending on their life stage. In this issue of Molecular
Ecology Resources, Parsley and Goldberg (2023) demonstrate, through a
lab-validated field study, that eRNA can be used to detect distinct life
stages of amphibians. This study elegantly demonstrates that eRNA can be
used not only to detect invasive or endangered species but also to
reveal population demographic information important for conservation.

Authors: Moreira Caritsa Scartaty , Lopes Alex Ferreira , Lucena Wenner Glaucio Lopes , Martins Orleans Silva
Published: March 2024

A qualidade e a quantidade de informações disponíveis em um mercado são reflexo do processo de elaboração das demonstrações contábeis das empresas, que podem sofrer impacto dos vieses comportamentais por parte de seus elaboradores, como o caso do excesso de confiança. Esses vieses podem ser uma explicação para a prática de possíveis comportamentos oportunistas quando da elaboração das informações contábeis. O presente estudo analisa a relação do excesso de confiança dos gestores com o Risco de Relatórios Financeiros Fraudulentos (RRFF) das empresas listadas na Brasil, Bolsa e Balcão (B3) no período de 2010 a 2021. Para tanto, o M-Score foi utilizado como proxy para o RRFF. Além disso, foi construído um ranking por meio da metodologia TOPSIS (com auxílio da entropia) para formulação da variável independente que mensura o excesso de confiança. A amostra analisada contém 211 empresas que foram analisadas por meio de regressão linear. Os resultados revelam uma relação negativa entre o excesso de confiança dos gestores e o RRFF, fornecendo assim, evidências de que as características pessoais dos gestores, neste caso, o excesso de confiança, têm impacto na qualidade das demonstrações contábeis. Ademais, a utilização do M-score como proxy para o RRFF traz maior robustez para os resultados aqui alcançados, uma vez que se utiliza de parâmetros contemporâneos, isto é, atualizados de acordo com a amostra e o período objetos de estudo.
INFLUÊNCIA DO PATROCÍNIO DE FUNDOS DE PRIVATE EQUITY E VENTURE CAPITAL NO GERENCIAMENTO DE RESULTADOS EM EMPRESAS QUE REALIZARAM IPO NO BRASIL
Authors: Moura Paulo Junio Pereira de , Machado Lúcio De Souza
Published: March 2024

O objetivo deste estudo consiste em analisar a influência exercida pela participação de gestores de capital de risco, Private Equity e Venture Capital, no gerenciamento de resultados de empresas brasileiras de capital aberto, no período de 2011 a 2019 (trimestralmente), que fizeram Initial Public Offering (IPO), empregando-se regressão quantílica. Esta investigação foi motivada pela lacuna existente na literatura nacional da relação entre gerenciamento por decisões operacionais reais e as empresas investidas por esses fundos. Para o cálculo do gerenciamento de resultados por accruals foi utilizado o modelo Kothari, Leone e Wasley (2005), enquanto para o cálculo do gerenciamento por decisões operacionais reais foi utilizado o modelo de Roychowdhury (2006). Os resultados demonstraram que as empresas que realizaram IPO no Brasil, patrocinadas por fundos de Private Equity e Venture Capital, apresentaram menor nível de gerenciamento de resultados por atividades operacionais em 3 quantis analisados (baixo, médio e moderado). No entanto, essa relação para o gerenciamento de resultados por accruals discricionários ocorreu apenas nos quantis 0,75 e 0,95, ou seja, moderado e alto. A principal contribuição da pesquisa foi demonstrar a importância de se realizar análise conjunta dos diferentes tipos de gerenciamento de resultados, além de complementar a literatura nacional que não investigou o gerenciamento de resultados por operações reais em IPO de empresas com a participação de gestores de capital de risco.

In the article, the following issues are considered: general principles of complex heat transfer in friction pairs of brake devices; radiant heat exchange from the rough surfaces of the metal friction elements of the brakes; the combined action of the fields of thermal conductivity and radiation in the metal friction elements of the brakes. The role of the thermal and dynamic boundary layers resulting from air-washing of metal brakes with open friction pairs and their effect on cooling is discussed. A new relationship between the Biot and Nusselt criteria is shown, which is presented in the form of thermal resistances of the surface and near-surface layers of the brake pulley rim. A comparison of the combined action of the fields of thermal conductivity and radiation in the metal friction elements of the brakes showed that the radiation efficiency is 1.5–1.7 W·m–2 times higher than the thermal conductivity. Radiation efficiency is the ratio of the power of the heat flux to the unit area through which the heat flux passes.

Authors: Tyvoniuk Volodymyr , Trach Roman , Wierzbicki Tomasz
Published: March 2024

Bridges are one of the key elements of the transportation infrastructure of each country, and the reliability of the entire transportation network depends on their functioning. Maintaining bridges in proper technical condition is the main task of bridge management, for which more and more countries use bridge management systems (BMS). This study is devoted to comparing different BMS, reviewing the main functions and modules and determining the perspectives of development and implementation of the latest technologies in BMS. The analysed bridge management systems were compared by functions such as storage of bridge passport data, initial information on the bridge condition, assessment of the bridge condition, forecasting of the bridge condition and consideration of different maintenance strategies. Some systems are distinguished by the fact that they can predict future bridge condition, offer optimal maintenance strategies and take into account losses not only for the operation of structures, but also for transportation. Prospects for the development of BMS were also identified: the use of neural networks, the introduction of building information modelling (BIM) and the Internet of Things (IoT).

Objective To explore associations of HLA class II genes (HLAII) with the progression of islet autoimmunity from asymptomatic to symptomatic type 1 diabetes (T1D).

Research design and methods Next-generation targeted sequencing was used to genotype eight HLAII genes (DQA1, DQB1, DRB1, DRB3, DRB4, DRB5, DPA1, DPB1) in 1,216 participants from the Diabetes Prevention Trial-1 (DPT-1) and Randomized Diabetes Prevention Trial with Oral Insulin sponsored by TrialNet (TN07). By the linkage-disequilibrium, DQA1 and DQB1 are haplotyped to form DQ haplotypes; DP and DR haplotypes are similarly constructed. Together with available clinical covariables, we applied the Cox regression model to assess HLAII immunogenic associations with the disease progression.

Results 1) The current investigation updated the previously reported genetic associations of DQA1*03:01-DQB1*03:02 (HR=1.25, p=3.50*10-3 ) and DQA1*03:03-DQB1*03:01 (HR=0.56, p=1.16*10-3), and also uncovered a risk association with DQA1*05:01-DQB1*02:01 (HR=1.19, p=0.041). 2) After adjusting for DQ, DPA1*02:01-DPB1*11:01 and DPA1*01:03-DPB1*03:01 were found to have opposite associations with progression (HR=1.98 and 0.70, p=0.021 and 6.16*10-3, respectively). 3) DRB1*03:01-DRB3*01:01 and DRB1*03:01-DRB3*02:02, sharing the DRB1*03:01, had opposite associations (HR=0.73 and 1.44, p=0.04 and 0.019, respectively), indicating a role of DRB3. Meanwhile, DRB1*12:01-DRB3*02:02 and DRB1*01:03 alone were found to associate with progression (HR=2.6 and 2.32, p=0.018 and 0.039, respectively). 4) through enumerating all heterodimers, it was found that both DQ and DP could exhibit associations with disease progression.

Conclusions These results suggest that HLAII polymorphisms influence progression from islet autoimmunity to T1D among at-risk subjects with islet autoantibodies.

The post-prandial glucose response is an independent risk factor for type 2 diabetes. Observationally, early glucose response after an oral glucose challenge has been linked to intestinal glucose absorption, largely influenced by the expression of sodium-glucose-co-transporter-1 (SGLT1). This study utilizes Mendelian randomization (MR) to estimate the causal effect of intestinal SGLT1 expression on early glucose response. Involving 1547 subjects with class II/III obesity from the ABOS cohort, the study employs SGLT1 genotyping, oral glucose tolerance tests, and jejunal biopsies to measure SGLT1 expression. A loss-of-function SGLT1 haplotype served as the instrumental variable, with intestinal SGLT1 expression as the exposure and the change in 30-minute post-load glycemia from fasting glycemia (∆30 glucose) as the outcome. Results showed that 12.8% of the 1,342 genotyped patients carried the SGLT1 loss-of-function haplotype, associated with a mean ∆30 glucose reduction of -0.41 mmol/L and a significant decrease in intestinal SGLT1 expression. The observational study linked a one standard deviation decrease in SGLT1 expression to a ∆30 glucose reduction of -0.097 mM/L. MR analysis paralleled these findings, associating a statistically significant reduction in genetically instrumented intestinal SGLT1 expression with a ∆30 glucose decreases of -0.353. In conclusion, the MR analysis provides genetic evidence that reducing intestinal SGLT1 expression causally lowers early post-load glucose response. This finding has a potential translational impact on managing early glucose response in type 2 diabetes

Objetivo: determinar índices de salud, nivel de actividad física y autoevaluación de la condición física en mujeres de carrera administrativa de una universidad pública durante la pandemia por COVID-19. Metodología: participaron 59 voluntarias, las mujeres fueron divididas en tres rangos de edad (18-26, de 27-59 y ≥60 años), se estimaron el índice de masa muscular, el índice cintura cadera y el índice cintura talla, fue aplicado el cuestionario mundial sobre actividad física y el cuestionario de autoevaluación de la condición física. Resultados: las mujeres de 27-59 años presentaron el riesgo cardiovascular más bajo con respecto a los otros grupos, la mayoría de las mujeres se encuentran en un nivel moderado o alto de actividad física, y se autoperciben con aceptable, buena y muy buena condición física. Conclusión: las mujeres a pesar de su dinámica laboral diaria realizan algún tipo de actividad física independiente de la edad, teniendo como consecuencia positiva bajos riesgos (a excepción de las mujeres de 18-26 años con respecto al ICC) de padecer enfermedades crónicas no transmisibles, Sin embargo, las mujeres administrativas pasan hasta 8 horas sentadas en su horario laboral lo que puede conllevar también a riesgos no solo cardiovascular sino ergonómicos.

The clean and renewable energy scenario has gone through a transformation process with the discovery of new generation sources and devices for their storage. Sustainable and efficient solutions are sought to satisfy the growing energy demand of today's population. The environmental problems related to fossil fuels are recognized throughout the world, but to abandon them and for renewable energies to cover current demand, they must not only deliver enough energy but must also be accumulated and transported. In this perspective, batteries play an important role in different areas, from energy storage to powering electronic devices, electric vehicles, etc. Electronic devices use relatively little power, so even small improvements in batteries have driven big changes in their performance and daily use. The functionalities of graphene and coltan make them ideal for a variety of applications, which are at the same time development opportunities for Colombia, such as water purification and desalination, catalyzing systems for the production of hydrogen and foams for lighting purposes, and a rapid heating element; graphene used as a photocatalytic coating material in smart buildings can purify the air in cities; It is also a promising material in the fields of printed electronics, sensors, graphene-based field-effect transistor (GFET) biosensors, optical biosensors, and photovoltaic cells. The possibility of incorporating graphene microchips implanted in teeth for bacterial detection and monitoring of oral hygiene is currently being studied, which could facilitate the study and prevention of periodontal diseases in the future; At the University of Manchester, new graphene condoms were obtained thanks to graphene composite polymers, which provide a higher heat transfer rate, improving sensitivity and the ability to disperse active drugs to prevent sexually transmitted diseases uniformly, pregnancy or even increase sexual pleasure. Graphene sheets have also recently been used to measure blood glucose levels through sweat and deliver pharmacological doses through the skin. This research focuses on a case study: the sizing of a Lithium battery with graphite in both electrodes as an alternative solution for greater energy storage. In this process, the participation of graphite in both electrodes is expanded, specifically in the coating of the cathode through layers to reduce losses and thereby improve battery storage. With this proposal, both the anode and the cathode will be made up of intercalator materials (graphite), different from the metallic lithium anode, which is dangerous, and the Li+1 ion can travel reversibly between them. As a result of the work, the structure of the new battery that will be built and tested in the following stages of the research was designed in SolidWorks software.

Energy democracy: Conceptual framework and research agenda for the Portuguese case
Authors: Ferreira Vera
Published: March 2024

The genesis of energy democracy is associated with the demand for a politicization of the energy transition. Its dimensions include democratic control of the energy sector, the redistribution of political and economic power, the universal right to renewable energy and social justice. Energy democracy provides a unique lens to critically assess the political, socioeconomic, and environmental implications of energy transitions. Therefore, based on the Portuguese case study, an analysis grid is developed that aims to facilitate the identification and evaluation of energy democratization instruments in the national context. A research agenda around energy futures in Portugal is also advanced.
