Authors: Stanić Sanja , Žuro Doris
Published: February 2024

Poremećaji jedenja eskaliraju u zapadnim, razvijenim zemljama 1960-ih godina kada započinje i njihovo sistematično proučavanje. Posljednjih desetljeća postaju globalni fenomen, što se povezuje sa širenjem zapadnih kulturnih obrazaca i ideala ljepote. Poremećaji jedenja su višestruko uzrokovani i nastaju djelovanjem bioloških, psiholoških i sociokulturnih faktora. Razvoj poremećaja jedenja najčešće se događa u adolescenciji, kada mladi postaju okupirani izgledom i tijelom. U radu im se pristupa iz sociološke perspektive, fokusiranjem na utjecaju sociokulturnih čimbenika rizika. Vršnjačke grupe, obitelj i mediji mogu utjecati na razvoj nezadovoljstva izgledom tijela i tjelesnom masom. Vršnjaci su važna referentna grupa. Brojna istraživanja su potvrdila da pritisak vršnjaka može biti motiv razvoja poremećaja jedenja. Odnosi u obitelji, obiteljsko okruženje i roditeljska očekivanja mogu utjecati na percepciju tjelesne mase i prehrambene navike djece. Medijski pritisak razvidan je kroz prezentaciju mršavog izgleda koji osigurava prihvaćenost i uspješnost. Posljednjih godina istraživanja se usredotočuju na utjecaj društvenih mreža. Societalne mjere u razdoblju pandemije COVID-19 negativno su utjecale na poremećaje jedenja. S obzirom na prirodu poremećaja jedenja prilikom tretmana, pojavljuju se etičke dileme. U Hrvatskoj su poremećaji jedenja društveno zanemareni i nedovoljno istraženi, s nepoznatim dimenzijama učestalosti i rasprostranjenosti. Procjene o broju osoba s poremećajem u Hrvatskoj se razlikuju, međutim, postoji slaganje o eskalaciji ovog poremećaja i spuštanju dobne granice. Poremećaji jedenja ugrožavaju zdravlje i ostvarenje životnih ciljeva osobe te najčešće negativno utječu na odnose u društvenim grupama u kojima se osoba kreće. Na razini društva poremećaji jedenja su značajan zdravstveni problem koji dugoročno opterećuje zdravstveni i socijalni sustav i odražava se na humani kapital. U zaključku se poremećaji jedenja promatraju u društvenom kontekstu.
Case Study of a Class on Classical Narratives Using ChatGPT
Authors: Lee Myeoung-Hyun , Kim Ji-Woo
Published: February 2024

This study analyzes the “Classical Narratives Retelling Project Using ChatGPT” conducted by the Department of Korean Language and Literature at Chung-Ang University in Korea in the first semester of 2023 in the course “Studies on Classical Literature Narrative”. The retelling project was carried out in stages, from the preliminary stage to the preparation, planning, and production stage. In collaborating with ChatGPT, learners repeatedly compared and reviewed their initial intentions with ChatGPT’s suggestions. In selecting, revising, and synthesizing the story with ChatGPT, learners continuously considered narrative integrity and the team’s retelling intentions (theme implementation). Their understanding of and interest in Korean classical narratives increased during this process. A 5-point Likert scale survey was used to verify this statistically and analyze the results, statistically confirming that the retelling process using ChatGPT had a positive effect on both understanding and interest in classical Korean narratives. To compensate for the limitations of the small sample size, we conducted an in-depth questionnaire survey. We analyzed the responses to confirm the effects of active participation and self-directed learning, deepening the understanding of classical narrative texts and forming a collaborative relationship between learners and ChatGPT. However, the limitations of using ChatGPT were identified as inaccuracies in ChatGPT data, answers that did not respond to learners’ intentions, uncreative ChatGPT narrative suggestions, and learners’ insufficient ability to utilize ChatGPT.

Published: February 2024

Background

The worldwide spread of monkeypox (mpox) has witnessed a significant increase, particularly in nonendemic countries.

Objective

We aimed to investigate the changing clinical symptoms associated with mpox from 1970 to 2023 and explore their interrelations.

Methods

In this systematic review and meta-analysis, 3 electronic databases were searched for English peer-reviewed studies conducted from January 1970 to April 2023 that reported any symptoms among confirmed mpox cases. We categorized the mpox epidemics into 3 periods: 1970-2002 (period 1, within the African region), 2003-2021(period 2, epidemics outside Africa), and 2022-2023 (period 3, worldwide outbreak). Following PRISMA guidelines, a meta-analysis was performed to estimate the pooled prevalence for each symptom. The correlation among symptoms was analyzed and visualized using network analysis.

Results

The meta-analysis included 61 studies that reported 21 symptoms in 720 patients from period 1, 39 symptoms in 1756 patients from period 2, and 37 symptoms in 12,277 patients from period 3. The most common symptom among patients from all 3 periods was rash (period 1: 92.6%, 95% CI 78.2%-100%; period 2: 100%, 95% CI 99.9%-100%; and period 3: 94.8%, 95% CI 90.9%-98.8%), followed by lymphadenopathy (period 1: 59.8%, 95% CI 50.3%-69.2%; period 2: 74.1%, 95% CI 64.2%-84.1%; and period 3: 61.1%, 95% CI 54.2%-68.1%). Fever (99%, 95% CI 97%-100%), enlarged lymph nodes (80.5%, 95% CI 75.4%-85.0%), and headache (69.1%, 95% CI 4%-100%) were the main symptoms in period 1, with a significant decrease in period 3: 37.9%, 31.2%, and 28.7%, respectively. Chills/rigors (73.3%, 95% CI 60.9%-85.7%), fatigue (68.2%, 95% CI 51.6%-84.8%), and dysphagia/swallowing difficulty (61.2%, 95% CI 10.5%-100%) emerged as primary new symptoms in period 2 and decreased significantly in period 3. Most other symptoms remained unchanged or decreased in period 3 compared to the former 2 periods. Nausea/vomiting had the highest degree of correlation (with 13 symptoms) and was highly positively correlated with lymphadenopathy (r=0.908) and conjunctivitis (r=0.900) in period 2. In contrast, rash and headache were 2 symptoms with the highest degree of correlation (with 21 and 21 symptoms, respectively) in period 3 and were highly positively correlated with fever (r=0.918 and 0.789, respectively).

Conclusions

The manifestation of symptoms in patients with mpox has become more diverse, leading to an increase in their correlation. Although the prevalence of rash remains steady, other symptoms have decreased. It is necessary to surveil the evolving nature of mpox and the consequential changes in clinical characteristics. Epidemic countries may shift their focus on the potential association among symptoms and the high synergy risk.

Uptake of digital health interventions for cardiometabolic disease: A ‘Think Aloud’ Study with British South Asian individuals (Preprint)
Authors: Ramasawmy Mel , Roland Persson Dan , Sunkersing David , Gill Paramjit , Khunti Kamlesh , Poole Lydia , Hanif Wasim , Blandford Ann , Sajid Madiha , Stevenson Fiona , Khan Nushrat , Banerjee Amitava
Published: February 2024

BACKGROUND

Digital health interventions (DHIs) could support prevention and management of cardiometabolic disease. However, those who may benefit most often experience barriers to awareness and adoption of these interventions.

OBJECTIVE

Among South Asian individuals, we evaluated user experience of DHIs to prevent and manage cardiometabolic disease to understand barriers and facilitators to initial and ongoing use.

METHODS

Among South Asian individuals recruited via primary care, community organisations, and snowball methods (n=18), we conducted “think-aloud” interviews using a reflective and reactive approach. Participants were asked to think aloud while completing a task they routinely do in a familiar DHI; and while setting up and completing a search task in a novel DHI, encouraging them to behave as if unobserved.

RESULTS

Participants included non-users, as well as those that used a range of DHIs as part of monitoring and improving their health. Lack of cultural specificity was highlighted as reducing relevance and usability, particularly relating to dietary change. Preferred features reflected individual health beliefs and behaviours, digital skills and trust in DHIs. For example, tracking blood glucose was considered by some to be positive, while for others it caused distress and anxiety. Similarly, some users found the novel DHI to be extremely simple to set up and use, and others grew frustrated navigating through initial interfaces. Many participants raised concerns about data privacy and needing to agree to terms and conditions which they did not understand. Participants expressed that with information and support from trusted sources, they would be interested in using DHIs as part of self-management.

CONCLUSIONS

DHIs may support South Asians to prevent and manage cardiometabolic disease, but it is important to consider the needs of specific user groups in DHI development, design, and implementation. Despite motivation to make health changes, digital barriers are common. Cultural appropriateness, and trusted sources (such as healthcare providers and community organisations) have roles in increasing awareness and enabling individuals to access and use DHIs.

BACKGROUND

Mobile health (mHealth) technologies have the potential to enhance cancer patient management, communication, and overall quality of life. The MyPal project, employing a participatory design approach, aims to provide palliative care support for patients with hematological malignancies through an electronic patient-reported outcomes (ePROs) eHealth platform.

OBJECTIVE

To evaluate the usability and user experience of "MyPal for adults," a co-designed palliative care mobile app intended to support adult patients affected by hematologic malignancies.

METHODS

Representative users participated in a 4-step usability study employing a think-aloud protocol, complimented with feature satisfaction, difficulty perceived, and design impression surveys along with a short semi-structured interview. Participants were also asked to provide qualitative feedback via the post-use System Usability Scale (SUS), User Experience Questionnaire (UEQ), and Post-study System Usability Questionnaire (PSSUQ). The data were analyzed along the lines of the ISO 9241-210 framework.

RESULTS

All participants found the intervention content useful, and they reported satisfactory usability, with a mean PSSUQ score of 2.458 and a SUS score of 68.9%. All aspects of the UEQ (Attractiveness, Perspicuity, Efficiency, Dependability, Stimulation, Novelty) surpassed usability quality benchmarks. Identified usability issues primarily related to effectiveness and efficiency as defined in ISO 9241-210.

CONCLUSIONS

In this study, we conducted a comprehensive usability evaluation of the MyPal for Adults app, a digital tool designed to enhance the palliative care experience. This approach identifies real-world usability issues, enabling iterative improvements in the eHealth platform's design. Our findings reveal a user-friendly interface and positive patient experiences. This study emphasizes the need to enhance palliative care mHealth platform usability, offering insights to improve palliative care for cancer patients.

Published: February 2024

BACKGROUND

The utilization of telemedicine has increased notably since the onset of the pandemic. Understanding the influence of telemedicine on health care costs and utilization can contribute to the monitoring and evaluation of telemedicine programs.

OBJECTIVE

This scoping review aimed to document the potential impact of telemedicine on health care costs and utilization across diverse health care contexts and to offer a summary of the statistical methodological approaches employed in assessing the impact of telemedicine on health care costs and utilization.

METHODS

A literature search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews guidelines, spanning the last 10 years across 3 electronic databases: PubMed/Medline, Web of Science, and Scopus. The search strategy was in accordance with the PICO criteria; patients were defined as the target population; telehealth or telemedicine was defined as the intervention; and standard care or before-and-after self-comparison was defined as the comparison, with health care costs and utilization as the outcome measures. Additionally, the six different structural layers of the TOAST framework for telehealth services were utilized to characterize the interventions. The findings were synthesized and are presented in tables and figures for clarity.

RESULTS

Out of a total of 4,454 identified articles, 14 were selected for review, with approximately 36% (n=5) focusing on chronic conditions. The delivery modalities included telephone call, videoconference, web portal, and smartphone applications, mainly spanning teleconsultation, telemonitoring, and teletherapy with clinicians and nursing support or health care team involvement. Approximately 86% of the studies employed standard face-to-face clinical visits for the control group. Six out of the 12 studies evaluating health care costs and four out of the seven studies assessing health care utilization revealed statistically significant improvements in telehealth compared to the control group. In addition, approximately 43% of the studies conducted univariate and multivariable analyses, with half of the studies incorporating adjusted analyses to control for confounding variables.

CONCLUSIONS

Our scoping review suggested that, in the treatment phase, compared with standard face-to-face clinical visits, telemedicine has the potential to decrease health care costs and optimally utilize health resources. Additionally, a regression model was the most commonly used statistical approach for assessing the impact of telemedicine.

Authors: Wijaya Syifa Indi , Ryshang Bathari Anggraini Citra , Wiedyaningsih Chairun
Published: February 2024

According to the 2018 Indonesian Basic Health Research data, the prevalence of hypertension in the Yogyakarta Special Region (11.0%) is higher than the national average of 8.8%. Hypertension with chronic kidney failure is currently a prevalent and increasing issue. This study aimed to investigate the pattern and rationality of antihypertensive use in hypertension patients with chronic kidney failure (CKF) participating in the National Health Insurance (Jaminan Kesehatan Nasional/JKN) program at Universitas Gadjah Mada (UGM) Academic Hospital period of 2020 to 2022. The study was conducted using quantitative descriptive non-experimental methods. Data collection was carried out retrospectively through medical records of patients diagnosed with hypertension with CKF (ICD I12.0). Samples were selected using purposive techniques and analyzed by comparing the suitability of drug selection with standard hypertension therapy with CKF based on JNC 8 and NKF-K/DOQI, including the rationality of their use. A total of 68 patients over the age of 18 were used as samples. The The majority of drug groupsresults showed that a combination of 2 drugs is more dominant (52.9%) compared to monotherapy (29.4%) and a combination of 3 drugs (17.6%). The majority of drug groups used were angiotensin receptor blockers (ARBs), especially candesartan (45%). ARB and calcium channel blockers (CCB), especially candesartan+amlodipin (50%), and ARB +CCB+diuretic, especially andesartan +amlodipine + furosemide (33%).. The rationality of drug use showed that 66.2% in the right indications, 89.7% the right drugs, 100% in the right patients and 85% the right doses. Therefore, health workers still need to make efforts to encourage rational drug use.

Published: February 2024

Objective: Maize (Zea mays L.) is a crop that has been widely cultivated in Indonesia. Using corn kernels on a large scale will produce much corn cob waste, usually unused. According to the literature search, corn cobs’ phytochemical studies and pharmacological activities still need to be improved. This study aims to determine the content of secondary metabolites (metabolite profiling) and their antityrosinase and anti-aging potential.

Methods: Corn cobs were macerated with methanol and fractionated with n-hexane, ethyl acetate, and butanol. The phytochemical profiling approach of the methanol extract was performed by liquid chromatography-mass spectra (LC-MS/MS). Anti-tyrosinase and anti-aging bioactivity were evaluated by thin layer chromatography (TLC)-bioautography and IC50 spectrophotometrically.

Results: The evaluation results show that the butanol fraction leads to a potential value (IC50 99.92 µg/ml). Several compounds, especially flavonoid compounds (including catechin; kaempferol 3-arabinofuranoside 7-rhamnoside; 6,8-Di-C-beta-D-arabino pyranosyl apigenin; 5,7-Dihydroxy-8,4’-dimethoxyisoflavone) were identified by LC-MS/MS by comparing the molecular mass of MS/MS data with literature data.

Conclusion: Based on this study, it can be concluded that butanol is the fraction that most actively inhibits tyrosinase, elastase, and collagenase enzymes, which means it potentially becomes a new anti-aging candidate.

Published: February 2024

Objective: In general, people with diabetes mellitus will experience disturbances in fat metabolism that lead to hypercholesterolemia. This study aims to determine the effect of ethyl acetate fraction hibiscus calyx on blood sugar, blood cholesterol level, and pancreas histology in diabetic Wistar Kyoto rats induced by streptozotocin.

Methods: Thirty-six Wistar Kyoto rats were induced with intra-peritoneal streptozotocin at 55 mg/kg BW and stabilized for five days to obtain diabetic conditions. Diabetic animals were divided into four groups; the diabetic group was given vehicle, the glibenclamide group was given 0.45 mg/kg BW of Glibenclamide, and two groups were administered the ethyl acetate fraction of hibiscus calyxes (EAFHC) at doses of 100 mg/kg BW and 200 mg/kg BW for five days. Fasting blood sugar and lipids (total cholesterol and triglycerides) were measured on days 0, 1, 3, and 5. Pancreats were collected on days 1, 3 and 5 for weighing and histology examination. All data were analyzed using two-way ANOVA followed by the Duncan Multiple Rank Test (DMRT).

Results: EAFHC significantly reduced fasting blood sugar and total cholesterol (p<0.05) but did not have a significant effect on triglycerides (p>0.05). Histology examination showed that EAFHC repaired pancreatic damage, as seen from the decrease in pancreatic histology scores (p<0.05), but the organ ratio did not show a significant improvement (p>0.1). 

Conclusion: This study revealed that EAFHC could be an alternative medicine in managing blood sugar levels and total cholesterol and improving pancreas function in associated models of diabetes mellitus hypercholesterolemia complications.

Objective: This study aims to determine the wound-healing activity of turmeric essential oil (TEO) collected from seven growing locations in West Sumatra, classify it based on fingerprint patterns of IR spectra combined with chemometrics, and identify their metabolite profiling using GC-MS spectroscopy.

Methods: Fresh turmeric rhizome was extracted by the hydrodistillation method. TEO classification was carried out by PCA (Principal Component Analysis), and PLS-DA (Partial Least Squares-Discriminant Analysis) was used for predicting characteristic functional groups and metabolites (VIP>1) in TEO. Wound healing activity was performed using in vitro fibroblast cell proliferation and migration assay. Data analysis was performed using one-way ANOVA with a 95% confidence level.

Results: PCA analysis based FTIR spectra was able to determine highland and lowland-originated TEO. The metabolites responsible for TEO classification were α-Phellandrene and D-limonene. The result showed that TEO originating from both lowlands and highlands enhanced fibroblast cell proliferation and fibroblast cell migration.

Conclusion: The combination of IR spectral fingerprint patterns and chemometric analysis could classify TEO based on the height location of growth. The results showed that the altitude of the growing location had no significant effect on the wound-healing activity of TEO from West Sumatra (p>0.05).

The objective of this study was to evaluate the impact of applying electrostatic field (EF)–assisted thawing on the quality attributes of previously frozen beef striploin. Beef striploins from both sides of 12 USDA Choice carcasses were halved, frozen at −40°C, and thawed under 4 EF voltage treatments: 0 kV (control), 2.5 kV, 5 kV, and 10 kV. After reaching the internal temperature of −1°C, striploins were weighed for yield calculation, swabbed for microbial analysis, fabricated into steaks, and assigned to either 0- or 14-d aging period and retail displayed for 0 or 7 d. Subjective and objective color measurements were taken during the retail display. Upon completion of retail display, Warner-Bratzler shear force (WBSF), cook loss, sarcomere length, troponin-T degradation, muscle fiber spacing, lipid oxidation, antioxidant capacity, pH, and proximate analysis were performed. All EF treatments increased purge loss compared to the control (P<0.05) and did not improve thawing speed, with samples from 10 kV actually taking the longest to thaw (P<0.05). The 2.5 kV and 5 kV samples aged 14 d showed less discoloration than those from 0 kV and 10 kV, and 5 kV samples aged 14 d had higher a* than those from the other treatments (P<0.05). Samples thawed under 10 kV showed a reduction in WBSF compared to the control (P<0.05), but there was no impact of EF on aerobic plate count, sarcomere length, troponin-T degradation,relative fat %, crude protein %, moisture %, purge protein concentration, pH, lipid oxidation, or antioxidant capacity for either the hydrophilic (water soluble) and lipophilic (lipid soluble) portion of the samples (P>0.05). Overall, our study determined that there was no economic benefit to apply EF during thawing regarding yield and purge loss. However, the application of EF may improve tenderness and extend shelf life of beef during retail display.

Published: February 2024

Objectives This study aims to review and summarize deep learning techniques that have been developed to date and to discuss how they can be applied in practice to artificial intelligence-based psychology counseling robots.
Methods To examine the latest deep learning techniques utilized in artificial intelligence psychological counseling, an extensive literature search was conducted for research papers and relevant books from both domestic and in-ternational sources in the fields of emotion analysis, facial expression generation, and text generation.. For do-mestic literature, databases such as RISS and KISS were utilized, and for international literature, research paper search sites including ERIC (ProQuest), JSTOR, and Google Scholar were employed.
Results When applying artificial intelligence in psychological counseling, the prominent technology of interest in-volves recognizing emotions from the interlocutor's facial expressions and generating similar expressions, or rec-ognizing emotions from sentences spoken by the interlocutor and generating responsive sentences. The study in-troduced the concepts of machine learning and deep learning and explained the workings of deep learning techni-ques, such as CNN (Convolutional Neural Network), RNN (Recurrent Neural Network), LSTM (Long Short Term Memory), Transformer, BERT (Bidirectional Encoder Representations from Transformers), GPT (Generative Pretrained Transformer), and GAN (Generative Adversarial Network). These techniques are founded on the princi-ples derived from human brain functioning. Particularly, emotion recognition programs through image analysis have predominantly relied on CNN, while research in the realm of language has advanced with the utilization of GPT-2, LSTM, and similar methods.
Conclusions Among the existing deep learning techniques, the recognition of emotions from the interlocutor's fa-cial expressions and the generation of similar expressions, or the recognition of emotions from sentences spoken by the interlocutor and the generation of responsive sentences, are the technologies predominantly under scrutiny for their application in artificial intelligence-based psychological counseling. Nevertheless, rule-based chatbots continue to dominate the landscape. This paper explored the merits and demerits of AI-based counseling em-ploying such deep learning techniques. Looking ahead, there is a need for the advancement of technology that en-ables natural interactions, coupled with the essential verification of its effectiveness.
The Effect of Task Conflict on Collective Efficacy in University Team-Based Learning Environments: Testing a Cross-Level Moderation with Relationship Conflict
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Choi Sungwon
Published: February 2024

Objectives This study utilized a multilevel approach to investigate the influence of task and relationship conflicts among college team members on collective efficacy during university TBL and PBL classes.
Methods Over a span of 10 weeks, a total of 176 students were organized into 25 teams participating in a uni-versity calculus mathematics course, which was conducted using TBL and PBL methodologies. At the conclusion of the course, a survey was administered. The study employed a cross-level interaction analysis with random slope models.
Results The study revealed a significant cross-level moderation effect in the relationship between individual-level task conflict and collective efficacy moderated by team-level relationship conflict. In teams characterized by high relationship conflict, there was a positive correlation between team members' task conflict and collective efficacy. Conversely, in teams with low relationship conflict, team members' task conflict had little impact on collective efficacy. Relationship conflict negatively and significantly affected collective efficacy at both individual and team levels.
Conclusions This study empirically demonstrated that the influence of team members' task conflict on collective efficacy varies depending on the level of team relationship conflict. This underscores the importance of effective communication during periods of relationship conflict in teams. The study discusses implications for TBL and PBL for both scholars and practitioners.

Objectives This study aims to find out the structural relationship between work-family transition, daily life stress, and subjective happiness perceived by middle-aged married working women.
Methods For this purpose, using the 8th data from the Women and Family Panel provided by the Korea Women's Policy Institute, 3,756 married middle-aged working women aged between 40 and 60 were surveyed on work-family conflict, family-work promotion, family-work conflict, and family. -Workplace facilitation was se-lected as an exogenous variable, and daily stress and subjective happiness were selected as endogenous variables. The collected data were subjected to structural equation testing using PLS-SEM using various statistical techniques (e.g. exploratory factor analysis, reliability analysis, convergent validity, and discriminant validity, etc.).
Results The results are as follows. First, as middle-aged married working women's perception of work→family promotion increased, daily life stress decreased, and the higher the level of recognition for work→family conflict, family→workplace promotion, and family→workplace conflict, the higher daily life stress. Second, the higher the level of work→family facilitation perceived by middle-aged married working women, the higher the subjective happiness. Third, the higher the daily life stress perceived by middle-aged married working women, the lower the subjective happiness. Fourth, it was confirmed that daily life stress significantly mediates the relationship be-tween all sub-factors of work-family transition and subjective happiness.
Conclusions Through the analysis of the results, the most important factor contributing to the improvement of daily life stress and subjective happiness of middle-aged married working women is work → family promotion. To improve their subjective happiness, it could be achieved through work-to-family transition strategy which con-tributes to the reduction of daily life stress; of which the most important goal strategy in promoting work→family needs to be established.

Objectives The purpose of this study is to identify the latent profiles of high school students’ academic help-lessness and differences in career adaptability, and to explore the effects of GRIT, relationship with friend and re-lationship with teacher ad the predictors.
Methods Questionnaire data from the 4th wave of Korea Children and Youth Panel Survey 2018 (KCYPS 2018) were analyzed. To examine the latent profiles, latent profile analysis(LPA), Chi-square test, multinomial logistic re-gression model(MLR) were used.
Results First, as the result of LPA, three latent profiles were found called low level of academic helplessness group, mid level of academic helplessness group, and high level of academic helplessness group. Second, there was siginificant difference in the career adatability depending on the latent profiles. Low level of academic help-lessness group showed the highest career adatability and Low level of academic helplessness group showed the lowest career adatability. Third, as the result of MLR, GRIT, relationship with friend, and relationship with teacher had significant effects as the predictors, but their influence differed by the latent profiles.
Conclusions The results of this study suggest that the career adaptability is different by latent profiles of academic helplessness. and different interventions are effective by the latent profiles. Our findings have important im-plications for interventions to alleviate academic helplessness and increase career adaptability in high school students.

Objectives The purpose of this study is to apply PBL(Problem-Based Learning) to the teaching subject class of preservice early childhood teachers and to analyze how PBL affects the improvement of the key competencies.
Methods PBL was conducted for 15 weeks, focusing on making and solving problems that beginner early child-hood teachers may face in the educational field and to preparing a PBL class plan for infants. Participants in the study were 44 second-year early childhood education students who took education methods and educational technology class for the second semester of 2022 at H vocational college in Seoul. In order to analyze whether the PBL class of pre-service early childhood teachers is effective in key competencies, a pre-post survey was con-ducted to diagnose key competencies, and reflection journals and PBL results were collected and analyzed.
Results As a result of the pre-post examination, the performance of improving key competencies (creativity, con-vergence, challenge, and growth) through PBL classes showed a significant difference at the statistical .001 level. In particular, the degree of improvement was high in terms of openness to change, comprehensive thinking, goal orientation, and self-efficacy, which are sub-detailed competencies. As a result of analyzing the reflection journal, it was found that students improved throughout key competencies such as creative competency, convergence competency, challenge competency, and growth competency through PBL classes. In particular, as an early child-hood teacher in the future, they showed confidence in the application of PBL classes for infants, and they have expectations that infants, like themselves, will be able to grow through PBL. It also showed a sense of efficacy that various and complex problems that may be raised in the field of early childhood education can be solved coop-eratively through PBL.
Conclusions To improve the effectiveness of PBL classes, it is necessary to develop instructors' PBL teaching ca-pabilities, to understand the theoretical and practical instruction design and education methods, make efforts to enhance mutual learning and key competencies through PBL activities, and utilize various teaching methods and multimedia technologies.

Objectives This study aimed to validate AI and English Integrated Teaching Materials for High School Students to Improve Machine Translation Literacy.
Methods To accomplish this, we organized a group of experts in the field of English education and artificial in-telligence integrated education and conducted a Delphi survey. We collected opinions on the necessity of strengthening translator utilization skills, that is, machine translation literacy, as well as the goal, structure, and content of the classes, in order to validate foundational materials for lessons that enhance the utilization skills of artificial intelligence translation systems. After revising the contents, the second Delphi survey was conducted.
Results The validity of each sub-question was analyzed based on .49 which is the standard value for securing content validity when the number of participants in the expert group was 15. As a result of the 1st Delpi survey, it was found that it was not valid in the content structure(.33), the content of the third class(.33), and the content of the third class worksheet(.46). After revising the contents, the second Delphi survey was conducted. Statistically significant figures were secured in all items such as class necessity, design, structure, and content of each class. The validity of the artificial intelligence convergence English education contents was secured, and the Delphi survey was completed in the second round.
Conclusions AI-English integrated education is essential to improve Machine Translation Literacy. This study is of great significance in that it has validated AI integrated education contents that can strengthen Machine Translation Literacy by understanding the principles and differences of translators, identifying the causes of trans-lation differences, and judging translation errors. However, since Machine Translation Literacy and students' English skills are inseparable concepts, continuous research will be needed on integrated education methods that can improve them together.
