FEAR OF FAILURE AND SELF-ESTEEM AS PREDICTORS OF ACADEMIC PROCRASTINATION AMONG COLLEGE STUDENTS
Authors: Aysha Begum
Published: July 2023

In this study, the researcher investigated the role of fear of failure and different aspects of self-esteem (positivity, openness, competence, humility, self-worth, and learning orientation) in relation to academic procrastination. The primary data was collected from a sample of 200 students (96 males and 104 females) from St. Johns College, Agra. The students were selected using random cluster multistage sampling, and their age ranged from 17 to 25 years. The study utilized three scales for data collection: the Academic Procrastination Scale by Gupta and Bashir (2018), the Performance Failure Appraisal Inventory by Conroy (2003), and the Self-Esteem Scale by Dhar and Dhar (2015). The collected data was then analyzed using t-tests, Pearson correlations, and linear regression in SPSS-22. The results of the t-tests indicated significant differences between male and female students in terms of academic procrastination, self-worth, and fear of failure. Male students scored higher than female students in academic procrastination, while female students scored higher in fear of failure and self-worth compared to male students. The Pearson correlation analysis revealed a positive correlation between fear of failure and academic procrastination, and a negative association between the different subscales of self-esteem and academic procrastination. Furthermore, the linear regression analyses indicated that fear of failure and self-worth were predictors of academic procrastination among college students. In summary, this study explored the relationship between fear of failure, self-esteem, and academic procrastination. The findings suggest that fear of failure and low self-worth are associated with higher levels of academic procrastination among college students.
KEYWORDS: Fear of Failure, Self-Esteem, Academic Procrastination.

Authors:   Taegu Science University Defense Security Institute, Park Byung Kyu , Shin Sang Hoon
Published: July 2023

Diesel power plants come in a variety of shapes, from moveable mini-power plants installed in 40-feet standard container boxes to large capacity power plants. The world's largest diesel power plant listed in the Guinness Book of World Records is Jordan's Amman Asian power plant, which produces a total of 573 MW of electric power. It consists of 38 units of 15MW capacity, and KEPCO achieved high profitability through the power plant. If a large capacity of 40MW clsss is applied, it will be newly listed in the Guinness Book of World Records even if only 15 units are constructed. Therefore, large-scale overseas orders for diesel power plants that require large capacity are expected in the future. The purpose of this study is to derive a practical offset by performing the shaft alignment analysis for large capacity 40MW shaft system, and to infer the change of offset for larger capacity shaft system through the comparison with the 30MW shaft alignment which is the result of the previous research. As a result, the practical offset of shaft system for the 40MW diesel power generation equipment was derived through the bearing influence assessment. From the comparison of shaft alignment between 30MW and 40MW, it is considered to be a complex offset to calculate the height of the engine bearing from 50MW class.

Published: July 2023

This study attempted to present the direction and implications of ESG activities of lifelong education institutions through empirical analysis on the impact of ESG activities, psychological distance, and authenticity on educational participation intention. The main results of this study were, first, found that ESG's environment, society, and governance structure had a significant effect on psychological distance. Second, it was found that the environment and society had a significant effect on authenticity. However, it was found that the governance structure had no significant effect. Finally, it was found that psychological distance and authenticity had a significant effect on the intention to participate in education. The theoretical implications of this study first contributed to academic expansion through research on the environment, society, governance structure, psychological distance, and authenticity of lifelong learning institutions on learning participation intention. Second, a measurement question for ESG activities of lifelong learning institutions was presented. Third, it will be of academic significance in that it has expanded to separate ESG areas at each level at the governance level that have not been actively expressed in social responsibility or shared value creation activities that have been actively studied. Fourth, signal theory was applied to ESG management of lifelong learning institutions to contribute to the expansion of theory. As a practical implication of this study, practitioners should continue to inform them that they are sincerely working through advertisements and publicity so that learners can feel psychologically close in environmental and social activities. In addition, in order to secure authenticity at the level of governance, external audit institutions should be used and authenticity should be secured through a citizen participation audit system.
A Corpus-based Analysis of the Linguistic Complexity Levels of the Reading Passages in Three Asian EFL Countries’ College Entrance English Exams
Authors:   The Korea English Language Testing Association, Om Hye Rang
Published: July 2023

This study investigates the linguistic complexity levels of the reading passages of the foreign language (English) domain of the College Scholastic Aptitude Test (CSAT) in Korea and compares them with those in two other Asian EFL countries. For the study, the reading passages of the Korean, Chinese, and Japanese college entrance English exams from the 2018 to 2020 academic year were collected and analyzed based on the length, propositional content and organizational characteristics by using a variety of corpus linguistic tools. The Kruskal-Wallis test was administered in order to see if there was a statistically significant difference among the tests. Also, when between-group differences were detected, the Mann-Whitney U post hoc test was conducted to further look into significant differences between the CSAT and the other tests. Overall findings suggest that the reading passages of the CSAT English exam maintained the highest difficulty level among the three Asian EFL countries’ college entrance English exams, with cognitively demanding academically-oriented items, highly advanced vocabulary, complex syntactic structure and low readability. Based on the findings, this research is expected to shed light on the intention of incorporating criterion-referenced English assessment into the CSAT as well as provide pedagogical implications for test developers and education policy makers in Korea.
Direction of Improving Preservice Teachers’ Competence of Designing Primary English Lesson Plan: Focused on Scaffolding Based on Dynamic Assessment
Authors:   The Korea English Language Testing Association, Kim Jin-Seok
Published: July 2023

The purpose of this study is to present the direction of improving preservice teachers’ competence of designing primary English lesson plans focusing on scaffolding based on dynamic assessment. To achieve the purpose, three lesson plans demonstrated for microteaching in the 2023 Lecture of Primary English Methodology were analyzed in terms of scaffolding based on dynamic assessment in alignment with tasks according to the phases of pre-class, during-lass, and post-class. It was found in the result of analyzing the lesson plans that 1) learners’ zone of proximal development (ZPD) was not established based on dynamic assessment for learners to achieve the learning objectives, 2) macro-level scaffolding based on dynamic assessment was not designed appropriately and systematically for learners to improve their communicative competence in the phases of pre-class and post-class, 3) micro-level scaffolding based on dynamic assessment was not designed for learners to interact with a teacher and to answer questions related to lessons’ content in the phase of during-class, and 4) rating scales aligned with tasks were not established based on a variety of scaffolding for learners to effectively solve the problems or complete their tasks in collaboration with classmates. Based on the results, it was suggested that a preservice teacher needs to check and assess learners’ communicative competence considering a rating scale, which involves scaffolding such as feedback for learners to effectively complete their tasks in collaboration with classmates.
User perceptions of YouTube English learning content by host factors: Focusing on comment analysis using topic modeling technique
Authors:   The Korea English Language Testing Association, Choi Yunjeong
Published: July 2023

This study explored how users' perceptions and responses to YouTube English learning content vary depending on whether the host is a native or non-native English speaker. To this end, two YouTube channels, one hosted by a native English speaker and the other by a non-native English speaker, were selected, and user comments on the learning content were analyzed using the topic modeling technique. The findings revealed that users of both channels perceived the use of the content as a form of 'learning', studying English expressions, vocabulary, and pronunciation on their own as well as asking questions and checking their understanding through comments. On the other hand, there were clear differences in the comments of the two channels according to the host factor. In the contents of the native English speaker, more comments were revealed that users were aware of the host as a native English speaker rather than a mere content creator. These comments encompassed discussions on authentic English expressions and topics tied to American culture. Conversely, comments on the non-native English speaker’s contents revealed a positive evaluation of the host's personal capabilities and learning strategies. These findings indicated the variability of users' perceptions, reactions, and expectations based on the host, irrespective of similarities in content and delivery format. The results also emphasize the potential of YouTube as a platform for English learning and the significance of host-related factors in shaping user reactions to the content.

Authors:   The Korea English Language Testing Association, Cho Bokyung , Joo Hunwoo
Published: July 2023

The present study aimed to develop a prototype for applying the Nationwide English Listening Test for Secondary School Students for high school English classes. In order to serve the purpose of the research, a lesson plan was developed as an example of pedagogical use of the test by making a draft in collaboration with English teachers. Subsequently, the content and structure of the draft went through an examination of English education experts for improvement and was modified by referring to their review. The following study should be well worth the effort to suggest possible improvements in order to activate the pedagogical use of the test in the classroom. Firstly, it is necessary to develop and provide an online English teaching and learning support system to schools because the usefulness of the prototype can be maximized if students are allowed opportunities to ubiquitously prepare or review for English lessons on computers or digital devices. Secondly, it is also recommended to disseminate exemplary cases of utilizing the test for pedagogical purposes in school, for example, by holding English class demonstration contests or running model schools.

Authors:   The Korea English Language Testing Association, Zhang Xiaohui , Kim Hyun-Ju
Published: July 2023

This study aims to investigate effective teaching behavior (ETB) for undergraduate students among college teachers in China and to analyze their perceptions of ETB that contribute to academic success. In this study, a questionnaire was used with 152 college students as participants, and data analysis was conducted using SPSS ver. 23, including t-test, ANOVA, and factor analysis. The results revealed that teachers’ perception of ETB in blended learning (BL) contexts consists of four dimensions: classroom teaching organization, online learning management, diversified assessment, and individualized instruction. Among these dimensions, classroom teaching organization was perceived as the most effective, followed by online management, while diversified assessment and individualized teaching were considered less effective in implementing ETB in teaching practice. Furthermore, the study identified two categories of factors affecting ETB: internal factors of teachers (beliefs, capacity, and motivations) and external factors (online platforms, institutional environment, and students’ performance). The research findings suggest that the online platform factor and environment factor have the highest correlation coefficient with ETB, while the teacher factor has the lowest. Based on the findings, the study proposes implications and suggestions, such as building online resources and enhancing the multifaceted roles of instructors in BL contexts, to optimize teaching practices in higher education and enhance students’ satisfaction and academic achievement.
Perception of Students and the Mediating Effect of Acceptance, Interactivity and LMS on Integration of Technology in HEIs
Authors: GYAU Yaw Odame , Semarco Stanley Kwame Marcus
Published: July 2023

Although the phenomenon of technology is gradually being integrated into tertiary education in Ghana, the perceptions of students to adopt and adapt to learning technologies for smooth integration of technology into academic programmes in public universities is an issue of concern. From the Constructivist and Positivist paradigm, this study adopted the quantitative approach and the purposive and quota sampling technique to solicit data from 1704 level 400 students in six (6) accredited public universities. Adopting the regression analyses approach with ten hypotheses tested the results were analyzed with PLS-SEM. The study found that the perceptions of students significantly impact the integration of technology. Indirectly, Students' Acceptance and Adjustment (AA) to use technology and Learning Management System (LMS) usage significantly mediates the relationship between the Perception of Students (PS) and the Integration of technology (IG). Furthermore, students' acceptance and adjustment to adopt technology and the use of the LMS, are key predictors of the integration of technology, but Interactivity is a weak predictor of the integration of technology into academic programmes in the topmost public universities in Ghana.
Can Housing Hedge Against Inflation?
Authors:   Korea Real Estate Society, Choi Cha Soon
Published: July 2023

This paper examines the inflation hedging capacity of Korea’s housing return from January 1987 to December 2022. The exponential generalized autoregressive conditiuonal heteroskedasticity(EGARCH) model and a dynamic ordinary least squares (DOLS) regression were employed to study the hedging capacity of Korea’s housing return against expected and unexpected inflation over the short run and long run. The results that could be obtained through this paper is as follows. First, The empirical results show a hedge effect on expected inflation only in housing return excluding gold over the short term, but not in unexpected inflation. Second, Over the long run, housing and gold returns provide a positive inflation hedge against expected inflation only. Third, it is found that the price volatility of housing and gold have both a positive asymmetric effect on news shocks. Over the long run, an increase in wages is found to increase housing prices by promoting housing demand, While no similar evidence is found in money supply.Therefore, there is a need to implement a stable wage policy to stabilize the housing market.
A Study on policy measures of special self-governing provinces to prevent local extinction
Authors:   Korea Real Estate Society, Kim Sang Geun
Published: July 2023

The decrease in local population breaks the balance with the economic development of the region, fails to realize decentralization and balanced development, and eventually approaches the crisis of local extinction. The main causes of the population decline in the provinces were the natural decrease due to the low fertility rate and population aging, and the larger factor, the social decrease (population outflow). In the Special Self-Governing Province, it is necessary to break away from the policy practice of the central government and actively prepare policy measures to respond to local extinction by using its own special authority and position. Since the policy establishment of the central government related to the population decline crisis, such as the 「Basic Act on Low Fertility and Aging Society」 in 2006, was promoted in a uniform way, there are many problems that do not properly reflect the characteristics of each local government and the situation at the site. Accordingly, five measures are proposed for the Special Self-Governing Province to establish policy measures that are sustainable and reflect regional specialization.

O axé de antigos Itãns como literatura
Authors: Basso Jorge Garcia
Published: July 2023

As mudanças curriculares trazidas pela lei 10.639/2003, seguida de forma complementar pela lei 11.645/2008 (BRASIL, 2003; 2008), que determinaram o ensino de história da África, das culturas afro-brasileiras e indígenas na educação básica no Brasil, dinamizaram a luta política pela descolonização do currículo e da cultura escolar brasileira, desafiando educadores e gestores educacionais no que tange ao trabalho pedagógico, com vistas à superação do racismo epistêmico no cotidiano escolar. As alterações promovidas por essa legislação fizeram emergir aspectos complexos e centrais da elaboração da nacionalidade e da identidade brasileira, relacionadas às maneiras como as heranças indígenas, africanas e escravistas deixaram suas marcas. Desde meados do século XX, homens e mulheres de culturas profanadas e estigmatizadas vêm conquistando voz, pondo em evidência intimidades de agressões seculares contra determinados sujeitos e culturas, que abalaram fronteiras epistêmicas e campos disciplinares consolidados, essas novas vozes fazem estremecer “um passado que parecia definitivamente organizado”. Impondo-se como fontes valiosas que marcam a insurgência de cosmovisões e poéticas extraocidentais que chegaram aos “olhos e ouvidos de artistas e intelectuais sensíveis às diferenças e ao novo”, e vêm interrogando colonialidades de saberes e poderes (SARLO, 1995, p. 59-60).

Published: July 2023

This study investigated the relationship between the tourism trade balance and globalization. We developed a novel and encompassing approach to measuring the tourism trade balance, including several inflows and outflows. The responsiveness of the tourism trade balance is examined not only for globalization processes depicted by indicators like de facto economic, social, and political globalization but also for globalization policies, i.e., de jure globalization. A comparative analysis across countries - belonging to different income groups, different quartiles of the tourism trade, globalization, and economic growth - revealed considerable heterogeneities among the other grouping of countries for the tourism-globalization relationship. The study suggested that it is of utmost importance to recognize that countries with a high level of globalization and well-developed tourism industry are in a better position to materialize the benefits of globalization.

Published: July 2023

Hydraulic jumps produce so much turbulence that hydraulic energy is effectively converted to heat. The speed, form, and volume of obstructions in an open channel have a considerable impact on the characteristics of a fluid stream. To create a hydraulic leap, a numerical analysis of water flow was done for a two-dimensional open channel over three different forms of obstruction, each with three volumes. Because of the impact of the air, it is possible to think of the emulsion of air and water as a compressible fluid with a vacancy percentage (a second fluid). The volume of fluid model (VOF), linked with the turbulent model, has been used to study each type of obstruction. The second-order upwind technique incorrectly solves the two-dimensional Reynolds-averaged Navier-Stokes equations. The numerical technique is implemented using the straightforward approach that was devised using control volumes. A wide range of Reynolds numbers (Re), corresponding to various flow patterns, were calculated for. The results demonstrate that when the Reynolds number increases, the effect of the gas phases on the liquid phases increases. The boundary layer thickness in the upstream zone from the obstacle decreases with increasing Re, whereas downstream from the obstruction, the height of the recirculation zone rises. Profiles of the empty fraction reveal two zones that are consistent with a diffusion equation. This article observed an inversion of the pressure gradient in the pressure field, which caused the boundary layer to separate; this is known as the "back flow phenomenon." The results of the current work have been verified by comparison with those of related research projects, and the comparison has shown a commendable degree of agreement. Additionally, pressure in various areas of the obstacle and velocity were similar.

This study aims to produce a Fixed Wing-Vertical Takeoff Landing (FW-VTOL) design that has good aerodynamic characteristics on its wing and fuselage. The design process begins with determining the Design Requirement and Objective (DRO). According to DRO, the aircraft is designed to be able to operate at speeds of 14 m/s and an altitude of 120 m (cruise phase) above ground level. The Maximum Takeoff Weight (MTOW) of the planned is estimated using previous research data. Based on calculations, for it to have a flight time of 30 minutes, the MTOW of the FW-VTOL is 5.2 kg. The fuselage and wing of the FW-VTOL design were carried out by referring to the MTOW of 5.2 kg. Three candidate airfoils were proposed, and their aerodynamic characteristics were determined using XFLR5 software. The aerodynamic characteristics of the three proposed fuselage candidates are also calculated. At an angle of attack of 30, the Eppler 66 airfoil produces the most lift coefficient and the lift-to-drag ratio of 0.8775 and 94.152, respectively. While the NACA 4412 and S9000 airfoils create lift coefficients of 0.7963 and 0.7963, respectively. From the calculation of aerodynamic characteristics, the first, second, and third fuselage candidates produce drag coefficient values of 0.1397, 0.1576, and 0.1368, respectively. The aerodynamic characteristics of the airfoil and fuselage are then input into the decision matrix table. As a result, the selected airfoil candidate is Eppler 66, while we choose the fuselage design is the third fuselage candidate.

Thermal management is essential in photovoltaic (PV) systems for enhancing PV performance. Passive cooling with a phase transition material (PCM) is one method for managing overheated PV. Crude palm oil (CPO) is preferred in Malaysia since it is both sustainable and inexpensive. To assess the feasibility of CPO as a PCM, a parametric analysis focusing on the PV-PCM tilt angles, PCM thickness, and PCM encapsulation material was carried out numerically. ANSYS computational fluid dynamics software is used in this work. The two-dimensional model is used to simulate a monocrystalline PV surface with macro-encapsulated PCM placed among two aluminium layers. Each parametric analysis's temperature distribution on PV surfaces and temperature contour for PV-PCM for tilting angle and PCM thickness are also discussed. Validation work was also performed with 9.73% errors that were within the allowed range. The result reveals that when the tilt angle is near-vertical (90o) the natural convection flows more rapidly. The system's average front surface appears to achieve the melting point completely faster. The optimum thickness for CPO to perform is 80mm, which can store heat for around 4000s (66.67mins). Aluminium outperforms stainless steel and copper as a PCM encapsulant since it facilitated the melting process by absorbing more heat. CPO with 80mm thickness, aluminium encapsulated, and vertical orientation has significant potential for thermoregulation in systems, especially in Malaysian weather (27oC).

AbstractThe government has launched a Risk-Based Online Single Submission (OSS) licensing system or OSS-Risk Based Approach (RBA). OSS-RBA is a one-door licensing application/portal that includes permits at the Regency/City, Province, Ministry/Institution (K/L) and Ministry of Investment levels. This is because so far many investors have been hesitant to invest in Indonesia because the licensing process is quite long and not simple. The research uses literature studies and interviews to look at complex issues regarding the process of licensing services and requires an in-depth meaning analysis. Implementation of Government Regulation Number 5 of 2021 Concerning the Implementation of Risk-Based Business Licensing (OSS RBA) in Serang City DPMPTSP has been going well. However, the socialization provided to the community or business actors has not been evenly distributed, only given to representatives of business actors, business associations and technical OPDs administering permits online and face to face. identify constraints in each sector for further solutions to be sought and coordinated with related parties.Keywords: Policy implementation, Licensing, OSS RBA, DPMPTSP Serang City AbstrakPemerintah telah meluncurkan sistem perizinan Online Single Submission (OSS) Berbasis Risiko atau OSS-Risk Based Approach (RBA). OSS-RBA merupakan aplikasi/portal satu pintu perizinan yang mencakup periznan di tingkat Kabupaten/Kota, Provinsi, Kementerian/Lembaga (K/L), dan Kementerian Investasi.

Implementasi Peraturan Pemerintah Nomor 5 Tahun 2021 Tentang Penyelenggaraan Perizinan Berusaha Berbasis Risiko (OSS RBA) Pada DPMPTSP Kota Serang sudah berjalan dengan baik. Namun sosialisasi yang diberikan kepada masyarakat atau pelaku usaha belum merata hanya diberikan kepada perwakilan pelaku usaha, asosiasi usaha dan OPD teknis penyelenggara perizinan secara daring dan tatap muka, diharapkan dapat membuka komunikasi dan koordinasi secara intensif untuk layanan konsultasi dan pendampingan untuk mengetahui progress penerbitan perizinan sekaligus mengidentifikasi kendala pada masing-masing sektor untuk selanjutnya dicarikan jalan keluarnya dan dikoordinasikan dengan pihak-pihak terkait.Kata kunci: Implementasi Kebijakan, Perizinan, OSS RBA, DPMPTSP Kota Serang
Angiotensin-converting enzyme 2 G8790A polymorphisms are associated with COVID-19 severity
Authors: Pan Yan
Published: July 2023

Introduction: In order to prevent COVID-19 from progressing, angiotensin-converting enzyme 2 (ACE2) binds to SARS-CoV-2 and prevents the virus from entering target cells. Several studies have found a correlation between COVID-19 risk and the ACE2 G8790A polymorphism; nevertheless, it remains inconclusive. A meta-analysis with relevant articles was carried out to more accurately estimate the risk of COVID-19.
Methodology: We conducted a systematic review using PubMed, Embase, Cochrane Library, Scopus, Science Direct and Web of Science databases. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. A meta-package was adopted in STATA version 12.0.
Results: It was concluded that the ACE2 G8790A polymorphism was not associated with COVID-19 based on the data collected. Moreover, subgroup analyses stratified based on race proved that the ACE2 G allele showed association with increasing risk of COVID-19 severity in Asians (G vs A: OR = 4.07, 95% CI = 3.19-5.19; GG vs AA: OR = 10.01, 95% CI = 5.39-18.56; GA vs AA: OR = 3.57, 95% CI = 1.84-6.93; dominant model: OR = 8.05, 95% CI = 4.36-14.88; recessive model: OR = 3.83, 95% CI = 2.89-5.08).
Conclusions: The findings indicated that the G allele of ACE2 G8790A was related to an enhanced risk of COVID-19 severity in Asians. One possible reason is that ACE2 G allele was associated with a COVID-19 cytokine storm. Furthermore, Asians have higher levels of ACE2 transcripts than Caucasians and Africans. Therefore, a genetic factor should be considered when developing vaccines in the future.
Nasopharyngeal melioidosis: a case report

A 12-year-old boy was admitted after 11 days of fever and 2 days of nasal obstruction as well as swelling of a right cervical lymph node. Nasal endoscopy and computed tomography of the neck showed a nasopharyngeal mass occupying the entire nasopharynx, extending into the nasal cavity, and obliterating the fossa of Rosenmuller. Abdominal ultrasonography revealed a small solitary splenic abscess. Although a nasopharyngeal tumor or malignancy was initially considered, biopsy of the mass showed only suppurative granulomatous inflammation, and bacterial culture from the enlarged cervical lymph node yielded Burkholderia pseudomallei. The symptoms, nasopharyngeal mass, and cervical lymph node enlargement resolved with melioidosis-directed antibiotic therapy. Although rarely reported, the nasopharynx may be an important primary site of infection in melioidosis patients, especially in pediatric patients.

Laboratory workers are exposed to the risk of acquiring infections due to the manipulation of infectious materials. The biological hazard for researchers is seven times higher when compared with hospital and public health laboratory workers. Despite the implementation of standardized practices to control infections, multiple cases of Laboratory Associated Infections (LAIs) usually go unreported. There has been a lack of comprehensive epidemiological data regarding the situation of LAIs for parasitic zoonosis and besides, the available sources are not completely updated. Since most accounts of laboratory infections are organism-specific, this study has focused on common pathogenic/zoonotic species handled at parasitological laboratories and summarising the standard biosecurity protocols for the infectious agents. The main characteristics of Cryptosporidium spp., Entamoeba spp, Giardia duodenalis, Toxoplasma gondii, Leishmania spp., Echinococcus spp., Schistosoma spp., Toxocara canis, Ancylostoma caninum, Strongyloides stercoralis are considered in this review in order to assess the potential risk of developing occupational infections in the workplace along with stating prevention and prophylactic measures for each species. It was concluded that the LAIs from these agents can be prevented by using personal protective measures and good laboratory practices. However, further studies are necessary to better understand the environmental resistance of cysts, oocysts and eggs, with a view to select the most suitable disinfection methods. Furthermore, it is fundamental to constantly update epidemiological data of infection acquired by laboratory workers, to develop accurate risk indicators.
A deep learning approach of financial distress recognition combining text
Authors: Li Jiawang , Wang Chongren
Published: July 2023

The financial distress of listed companies not only harms the interests of internal managers and employees but also brings considerable risks to external investors and other stakeholders. Therefore, it is crucial to construct an efficient financial distress prediction model. However, most existing studies use financial indicators or text features without contextual information to predict financial distress and fail to extract critical details disclosed in Chinese long texts for research. This research introduces an attention mechanism into the deep learning text classification model to deal with the classification of Chinese long text sequences. We combine the financial data and management discussion and analysis Chinese text data in the annual reports of 1642 listed companies in China from 2017 to 2020 in the model and compare the effects of the data on different models. The empirical results show that the performance of deep learning models in financial distress prediction overcomes traditional machine learning models. The addition of the attention mechanism improved the effectiveness of the deep learning model in financial distress prediction. Among the models constructed in this study, the Bi-LSTM+Attention model achieves the best performance in financial distress prediction.
Infralittoral coralligenous reefs: structure and spatial variability of macroalgal assemblages

Coralligenous reefs are calcareous structures edified mostly by coralline algae that characterize the circalittoral zone of the Mediterranean Sea. However, in some cases coralline algae can constitute peculiar infralittoral biogenic reefs which have been studied less than the circalittoral ones. This study aims to contribute to the knowledge of infralittoral coralligenous reefs by describing their macroalgal assemblages on a large rocky platform off the Tuscany coasts, northwestern Mediterranean Sea. To this end, a multifactorial sampling design was used to describe the structure of the assemblages and to evaluate the variability of the system at multiple spatial scales. A total of 71 macroalgal taxa were found on the coralline algae. Macroalgal assemblages were well structured, with high biodiversity values. The dominant taxa included both photophilous and sciaphilous species, guaranteeing peculiar characteristics in these assemblages, above all if compared with the typical infralittoral and circalittoral macroalgal communities of the same geographic area. The assemblages showed greater variability at a small and intermediate spatial scale than at a large scale. Although infralittoral coralligenous outcrops constitute a peculiar system, they are still poorly understood and should not only be the object of specific studies but also be included in monitoring programmes.
