ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10–16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as “does not practice,” “practices ≤300 min/week,” and “practices >300 min/week” by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08–1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35–0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID. Conclusions: The adolescents who practice FRE >300 min/week are likely to have some level of BID and are less likely to report the desire to increase their silhouettes, regardless of their nutritional status.

Published: September 2024

Abstract Colombia is a tropical country with a rich fern flora. The Quindío Department is in an area which is undergoing significant environmental changes due to anthropogenic activities, such as coffee cultivation. Gleicheniaceae, a family of pioneer ferns, is known for preferentially occupying open, sunny, and disturbed habitats, such as roadsides. Our study aimed to conduct a taxonomic treatment of the Gleicheniaceae species in the Quindío Department in Colombia. Our results revealed the presence of 10 species distributed in four genera, with the Sticherus genus accounting for most of the species (seven in total). Notably, a new record of Sticherus (S. brevitomentosus) was found for Colombia, indicating the potential for the discovery of additional species in future studies. Furthermore, our results demonstrated that 42% of the 24 species reported in the Andean region were present in the Quindío Department, and Calarcá and Salento were the municipalities with the highest diversity. We have provided taxonomic descriptions for the genera and species, as well as an identification key, maps, images, and comments on the taxonomy and distribution of the species.
Da Encruzilhada Oceânica: Caminhos de uma Pedagogia Decolonial feminista no Exílio
Authors: Tribess Camila
Published: September 2024

Historicamente, nas sociedades patriarcais, mulheres são responsáveis pela educação de crianças e transmissão cultural em diversos níveis: linguístico, alimentar, artístico e de costumes. Nos processos de luta anticolonial, mulheres são vistas como fundamentais para a consolidação revolucionária nacionalista, no entanto, suas contribuições políticas e intelectuais são apagadas nas histórias oficiais. Este trabalho apresenta a atuação e circulação internacional de um grupo de mulheres timorenses que, no exílio em Portugal e Moçambique, desenvolveram uma pedagogia feminista decolonial e representam uma camada importante para a transmissão e circulação de conhecimentos, práticas e saberes. Em contato com as encruzilhadas culturais que o exílio forçou, geraram novas formas de luta e compreensão política para este grupo de mulheres. Em diálogo com as teorias decoloniais, este trabalho é parte de pesquisa de doutorado em andamento e propõe a perspectiva de uma pedagogia decolonial feminista.

This article tryes to initiate the concept of Minangkabau rhythm syllables, which is a method in music learning related to audiation in rhythm learning, the urgency in this study explores the basic elements of the audiation system that can be applied to music learning related to rhythm syllables based on local approaches, taking into account previous concepts that have been popular in recent schools. In West Sumatra, the concepts of syllable rhythm such as Zoltan Kodaly, Kannokol, American Style Syllables, and Edwin Gordon are not so popular, but environments such as schools and art studios have their own ways of approaching learning music related to pronouncing sounds, so that in this study it is addressed as an interesting and crucial thing to study and formulate further into formulations. The method used in this research uses a qualitative paradigm with a literature review approach. Where the concept of previous rhythmic syllables is used as a reference in analyzing, bringing up findings, and juxtaposing the findings with the initiated Minangkabau rhythmic syllable formula, so that the Minangkabau rhythmic syllables can be generalized and adapted, but still referring to the habits of the local community material. Based on the results of the analysis, like Gordon’s concept, it is found that syllables or audiation appear after the formation of rhythms, patterns and sound colors from an instrument, which can then strengthen the form of audiation into verbal form.

This paper discusses the Kutau martial arts ritual practiced by the people of Suro Village, Muara Beliti District, Musi Rawas Regency, South Sumatra Province. Kutau is one of the ancestral heritages consisting of a set of rituals. Kutau takes the form of traditional martial arts that has been developed by the Suro Village community. Applying the qualitative approach, this study aimed to systematically document all forms of rituals in Kutau and its functions within the Suro community. Data were collected through observation, interviews, and documentation, which were then analyzed using Victor Turner’s ritual approach and Talcot Parsons’ function approach. Results show that Kutau is a medium of communication between the community and their ancestors to pass down the Kutau knowledge, which is closely related to Suro people’s belief system. Kutau still prevails thanks to the latency function of the Kutau community, so that the whole system is able to survive and adapt to the current society.

Rambu Solo’ is one of the most expensive traditional funerals in the world. This has created a general impression that Rambu Solo’ must always be lavishly performed, although in reality it can be adjusted to the bereaved family’s financial circumstances. This research seeks to explain how Rambu Solo’ can be motivated by both urgency and prestige using Abraham Maslow’s humanistic psychology theory. This research applied the qualitative method. Data were collected by interviewing a traditional leader named Ambe Tawang with the aid of a local interpreter, Baharuddin Palepong, who lived in Lembang Palesan, Tana Toraja, South Sulawesi. After collection, the data were then analyzed, reduced, presented, and verified. This study found that only few people still perform Rambu Solo’ to gain prestige, while most people in Lembang Palesan perform it because of urgency factor, that has been passed down from generation to generation.
What Determines Satisfaction with Graduate School and Intentions to Complete it Among Modern PhD Students?
Authors: Marchuk L.A. , Gordeeva T.O.
Published: September 2024

The article focuses on the role of motivational factors in the successful completion and satisfaction with postgraduate programs. PhD students (N=155, M=26,8, SD=4,2, 63% women) participated in the study. The theoretical framework is based on self-determination theory, which provides an understanding of the sources of autonomous and controlled motivation for research activity. A battery of questionnaires was used to assess autonomous and controlled motivation for postgraduate programs (the Universal Perceived Locus of Causality scales, UPLOC, and the Doctorate-related Need Satisfaction Scale, D-N2S), publication activity, intentions to complete the postgraduate program, and satisfaction with it. The results of the study demonstrated that autonomy need satisfaction was a predictor of autonomous motivation and satisfaction with the postgraduate program, whereas competence and relatedness needs satisfaction were predictors of intentions to complete the postgraduate program. Path models also showed that autonomy need satisfaction is a predictor of low levels of controlled motivation, which in turn is a negative predictor of intentions to complete the postgraduate program and satisfaction with it. It is concluded that it is important to study and monitor motivational factors, considering their predictive power in relation to PhD students' performance. Recommendations are offered to supervisors and faculty to support PhD students' basic psychological needs for autonomy, competence, and relatedness to foster their voluntary engagement and success in the research process.
My Ideal University: Physical and Non-Physical Components of the Environment in Student Presentations
Authors: Verkhoturova M.V.
Published: September 2024

The article addresses the issue of identifying the needs of modern students in relation to the university educational environment. The study involved 48 architecture students aged 18 to 27 years (M=19.81; Mo=19; SD=1.82), including 83.33% girls (n=40) and 16.67% boys (n=8). The aim was to identify the most significant categories of the university educational environment. The research, which utilized a projective method – an essay titled "My Ideal University" – and content analysis of the responses, revealed that students consider non-physical categories to be the most important for effective and comfortable study. These categories include the organization of the educational process, the quality of the teaching staff, the curriculum, and opportunities for personal development. To confirm these results, a chi-square test was conducted, showing that non-physical categories of the educational environment were significantly more important than physical ones (χ2=14.812, df=1, p=0.001). The most prominent physical environment categories mentioned by students included the equipment of offices and classrooms, the aesthetic qualities of the space, well-organized university grounds, coworking spaces, and rest areas in the interior. The data obtained can provide practical recommendations for designing new campuses or renovating and reconstructing existing universities. Precisely determining the optimal conditions for an effective and comfortable educational process will help avoid excessive financial investments in improving the physical environment.

Authors: Shamionov R.M.
Published: September 2024

This study aims to clarify the role of value orientation in the satisfaction of basic needs and academic adaptation of students. It will allow us to set goals, which help to achieve psychological well-being. The study involved (N=390) students of pedagogical profiles of the university (35% men, 65% women), aged 17–22, average age 19,85, SD=3,17. The following methods were used in the study: A scale of satisfaction of basic needs (M.M. Johnston, S.J. Finney, 2010); a "Portrait value questionnaire" (S. Schwartz, 2012); a methodology for diagnosing academic adaptation (R.M. Shamionov, M.V. Grigorieva, E.S. Grinina, A.V. Sozonnik, 2022) and a questionnaire to establish socio-demographic characteristics. It is established that the preservation and openness values are positive predictors of satisfaction of basic psychological needs as an personal autonomy, competence and connection with others. The positive effect of preservation values and the negative effect of openness on variations in academic adaptation is mediated by satisfaction of basic needs for autonomy and competence, which respectively enhance or reduce these effects.

Напрямні (лінійні підшипники ковзання) зворотньо – поступального руху знаходять достатньо широке застосування в багатьох сферах діяльності людини. Проте на даний час відсутні обґрунтовані методи їх розрахунку, зокрема металополімерних напрямних. Подано метод розрахунку параметрів контакту у циліндричних металополімерних напрямних ковзання. На прикладі антифрикційного полімерного композитного матеріалу ДК6 на епоксидній основі, що використовується для відновлення триботехнічних систем ковзання, досліджено вплив навантаження, діаметра  втулки і радіального зазору на максимальні контактні тиски та їх розподіл у напрямній. Встановлено кількісні і якісні закономірності залежності контактних тисків від прийнятих чинників впливу: при зростанні навантаження у чотири рази максимальні контактні тиски та кути контакту зростатимуть удвічі незалежно від зміни величин радіального зазору та діаметра основи; збільшення її діаметра призводить до прямопропорційного зниження максимальних контактних тисків; збільшення радіального зазору вдвічі призводить до зростання урази тисків незалежно від зміни величини навантаження і діаметра основи. Закономірності зміни параметрів контакту від вказаних чинників подано графічно.

В материалах статьи рассмотрены: трибологические подсистемы различных типов фрикционных узлов тормозов; эксплуатационные параметры, принципы структурной приспосабливаемости и собственно структурная приспосабливаемость материалов пар трения тормозных устройств, а также их энергетические уровни. Оценена работа выхода частиц из микровыступов поверхностей трения металлополимерных сопряжений с учетом удельной нагрузки, скорости скольжения, поверхностной температуры и энергетических уровней приповерхностных слоев пары трения с соблюдением принципов структурной приспосабливаемости их материалов. Показано, что избыточная энтропия, генерируемая  трущимися поверхностями тормозных устройств, при Kf >>KT (где Kf и KT – кинематические константы химических реакций) отрицательно влияет на эксплуатационные параметры пар трения, повышая их энергонагруженность. По результатам выполненных исследований установлены закономерности формирования характеристик процессов, явлений, и эффектов на иерархических уровнях текстур трущихся материалов трибосопряжения при их электротермомеханическом фрикционном нагружении.

У загальному випадку втрати на тертя кочення і ковзання в опорних вузлах можуть досягати 30% сумарної потужності приводу, яка може становити і більше. Також мають місце інші механічні втрати на тертя кочення та ковзання, зокрема в зубчастому зачепленні приводу обертання агрегату. В статті представлено результати експериментальних досліджень процесу тертя кочення двох циліндричних роликів на дослідному стенді, що моделює роботу опорного вузла обертового агрегату. В основі розроблення експериментального стенду закладено три критерії подібності (геометричної, кінематичної і динамічної) до діючого обладнання. Стенд виконано із геометричним масштабом пари кочення M. Навантаження в контакті визначали за умови рівності контактних тисків, що виникають між бандажем і роликом на натурному обладнанні і досліджуваними роликами на експериментальному стенді. Отримано визначальні силові і кінематичні характеристики дослідної моделі. Визначено момент тертя кочення залежно від колової швидкості кочення та радіального навантаження на пару кочення. На основі експериментально отриманих результатів значення коефіцієнту тертя кочення сталевих роликів рекомендовано значення його меж. Визначено, що значення коефіцієнту тертя кочення може коливатися внаслідок зміни швидкості кочення в певних межах, а далі зростати з подальшим збільшенням швидкості. Встановлено закономірності зміни коефіцієнтів тертя кочення від швидкості кочення та радіального навантаження за різних значень контактних тисків, що відповідають реальним значенням в опорних вузлах промислових обертових печей. На підставі цього визначено втрати потужності на тертя кочення в опорних вузлах великогабаритних обертових агрегатів, неперервної дії, зокрема барабанних сушарок, грохотів, тощо виходячи із рекомендованих за результатами експериментальних досліджень значень коефіцієнту тертя кочення.

Image Steganography based on Fernet Symmetric Encryption and Odd-Even Pixel Modification
Authors: Sultana Habiba , Deena Faria  , A.H.M. Kamal
Published: September 2024

The combination of steganography and cryptographic approaches for information concealing has piqued the curiosity of numerous researchers. We also integrate those two methods in our research. Using Fernet symmetric encryption and odd-even pixel alteration, this research presents a novel method for image steganography that distributes the data equally throughout the image. To create a stego image, the sender uses a password to encrypt a secret message embedded into an image's red channel. The stego image resembles the original cover image, while the underlying secret data is concealed from human view. The main goals of the system—encryption, consistent data concealing, and message retrieval—were all successfully met. Before integrating the secret data into the image, it can be easily and successfully secured using symmetric encryption using the Fernet cipher. By adding another layer of security to the system, the password feature makes it harder for unauthorized users to access hidden data. By altering image pixels according to whether they are odd or even, the odd-even pixel modification-based steganography approach makes it possible to conceal data. Based on the experiment's results, it can be concluded that this approach embeds concise messages with a high visual quality.

Published: September 2024

Current studies on behavioural biometrics authentication have been focused on the use of deep learning and keystroke dynamics but the aspect of conscious optimization of the algorithm in order to obtain best outcome has not been considered. This study employed and incorporated Bayesian algorithm into Recurrent Neural Network to build a Keystroke Behavioural Biometric (KBB) authentication model used against social engineering attacks. The model begins with importing the keylogging dataset for data pre-processing, feature extraction, and RNN algorithm was used to build the KBB model. Hyperparameter tuning was done to achieve optimal results. A traditional optimizer called Adaptive Momentum Estimation (Adam) was used and evaluated so as to estimate the impact of optimization in model inferencing. RNN model result with Bayesian optimization technique shows a better performance than the result of RNN model with ADAM optimization. The essence of incorporating and evaluating the best optimization technique is to come up with an effective and accurate model for behavioural biometric authentication, that could mitigate effectively against social engineering attacks.

Ziemia obiecana Molochowi – Cmentarzysko Władysława Reymonta w perspektywie widmontologicznej
Authors: Hac-Rosiak Barbara
Published: September 2024

Celem artykułu jest odsłonięcie nowych sensów symbolicznych Cmentarzyska Władysława Stanisława Reymonta poprzez poddanie tekstu oglądowi z perspektywy widmontologii, koncepcji filozoficznej i metodologii badawczej autorstwa Jacques’a Derridy. Szczególnie istotny jest dla niej motyw światła i cienia oraz emersji, stopniowego wyłaniania się obiektów z mroku. W tekście światło kojarzone jest z wiedzą, informacją, dźwiękiem rozmowy, zaś ciemność oznacza milczenie, napięcie i oczekiwanie. Zwycięstwo światła nad cieniem ma silne konotacje symboliczne, zarówno w kontekście religijnym – triumf dobra nad złem, jak i filozoficznym – oświecenie wypierające obskurantyzm. W teorii Derridy rola światła jest nierozerwalnie związana z kategorią obecności, objawienia istnienia. Filozof dekonstruuje to klasyczne znaczenie, wprowadzając pojęcia widm, śladów oraz odraczania apokalipsy, rozumianej jako odsłonięcie prawdy. Analiza widmontologiczna prowadzi do konstatacji, że osobiste doświadczenia autora stały się źródłem widma rewolucji, zaś tekst jest manifestacją jego nawiedzenia. Czerwień Cmentarzyska to wcielenie apokalipsy, zapowiedź kataklizmu nadciagającego nad fabryczne miasto, z pewnością inspirowane Łodzią przełomu XIX i XX stulecia.
„Bisogna essere volpe e leone” – interferencja cenzury i recepcji w procesie twórczym Bożycy Bronisława Trentowskiego
Authors: Lipiec Emilia
Published: September 2024

Celem artykułu jest prześledzenie wpływu cenzury na powstawanie zachowanej w rękopisie Bożycy lub teozofii oraz na decyzje wydawnicze Bronisława Trentowskiego, jednego z wiodących polskich filozofów romantyzmu. Ze swego traktatu z zakresu filozofii Boga autor opublikował za życia tylko dwa fragmenty. Stawiam w artykule tezę, że dzieło nie zostało w pełni opublikowane z powodu złej recepcji owych fragmentów pośród polskich odbiorców, których tożsamość narodowa w okresie zaborów zawisła na spójności polskiego Kościoła katolickiego, a nie bezpośrednio z powodu cenzury. Kolacjonowanie opublikowanych fragmentów z rękopisem dzieła ujawnia różnice o charakterze ilościowym i jakościowym specyficzne dla każdej z publikacji: jednej wydanej w Paryżu bez cenzury oraz drugiej opublikowanej w Poznaniu pod cenzurą pruską. Analiza wyników kolacjonowania w zestawieniu z korespondencją Autora z przyjaciółmi i wydawcami pozwala wnioskować o wpływie cenzury na proces twórczy Bożycy pod postacią autocenzury. Pozwala też uznać gotowość Autora do wydania dzieła za cenę kompromisu z cenzurą instytucjonalną, ale nie za cenę odstąpienia od poglądów na kwestię filozofii Boga w celu zdobycia uznania odbiorców.
Identification of the genetic determinants of shovel-shaped incisors and Carabelli’s cusp
Authors: Erbil Fatma Nur , Merriwether David Andrew
Published: September 2024

Shovel-shaped incisors (SSI) and Carabelli’s cusp (CC) are noteworthy human dental non-metric traits which presence and degree of expression have been reported to cluster within distinct populations. Recent advances in developmental biology suggest that SSI and CC are likely under polygenic developmental control; therefore, genetic variation in multiple genes is likely to contribute to differential SSI and CC expression. The exact genetic mechanisms underlying variation in SSI and CC development, however, remain mostly unknown. This study aims to identify whether variation in the basal DNA sequences of six candidate genes, NKX2-3, SOSTDC1, BMP4, FGF3, FGF4, and WNT10A, has any impact on SSI and/or CC expression. Study methods involve collection of saliva samples and dental data from 36 participants. The Arizona State University Dental Anthropology System (ASUDAS) has been used to score SSI and CC expression. Next-generation sequencing (NGS) methods were utilized to sequence the entire gene region of the candidate genes. Spearman’s correlation test was used to score the relationship between the genotype and degree of trait expression of participants. Fifteen SNPs/INDELs belonging to SOSTDC1, FGF3, FGF4 and WNT10A were significantly associated with SSI and/or CC expression. No SNPs/INDELs were detected in the genes BMP4 and NKX2-3 that significantly contributes to observed phenotypes. FGF3, FGF4, SOSTDC1 and WNT10A were possibly involved in the formation of shoveling and Carabelli’s cusp. However, because of the small sample size, more studies are needed to confirm their role and rule out any potential role of NKX2-3 and BMP4 in the production of SSI and CC.
Ministry of national education’s provincial administrators’ views on distance vocational education
Authors: Çalışkan Emre
Published: September 2024

One of the biggest advantages of technology is that people have the opportunity to access information faster and easier. In this way, people can update their knowledge in the face of constantly changing and self-updating information and improve their existing knowledge by replacing it with new ones. This rapid development has pushed educators to seek new ways in learning-teaching processes, and technology is increasingly being included in our education processes. Among the developed models, the distance education model is the most preferred in our education processes. This study aimed to examine the kind of results that will be obtained when the distance education model is integrated into in-service training. The descriptive survey method was used in the research. The opinions and experiences of the managers were used through the semi-structured interview form on the subject. According to the results of the research, it has been determined that the distance of in-service training does not cause problems in general, but it is not as effective as face-to-face training in terms of socialization and understanding of the subjects.
Keywords: Administrator; distance education; in-service training; Managers; vocational education.

Authors: Fitri Diah Oktadewi  , Romdlon Mahindra Awwaludin , Laksitasari Anindita , Hidayah Riski Amalia
Published: September 2024

Background: Oral health literacy (OHL) has an important role as a medium for health promotion and efforts to prevent oral diseases through oral health behavior changes. Purpose: This study aims to determine OHL and its correlation with oral health knowledge, attitude, and oral health practice among college students. Methods: This cross-sectional study was conducted on 583 students of Jenderal Soedirman University in 2020, as the students come from different provinces in Indonesia. The Indonesian Oral Health Literacy Questionnaire was used to assess OHL. A self-designed questionnaire was used to assess oral health knowledge, attitude, and oral health practice. Results: Most students had good OHL, knowledge, and attitude toward oral health (90.7%, 84.6%, and 90.5% respectively). A Pearson correlation test showed a correlation between OHL and oral health knowledge (p = 0.044) and attitude (p = < 0.001). The Fisher exact tests showed a correlation between OHL and snacking frequency, tooth-brushing frequency, tooth-brushing time, and toothbrush changing time. The better the OHL, the better the knowledge and attitude. There was no correlation between OHL and sweet food eating frequency, the use of cleansing aids, dentist visit frequency, and the first action taken when experiencing toothache. Conclusion: OHL has a correlation with oral health knowledge and attitude. However, OHL is only related to some oral health practice indicators. The results of this study are expected to be taken into consideration when formulating strategies to improve oral health within the university.
Cancer-associated fibroblast cell surface markers as potential biomarkers or therapeutic targets in lung cancer
Authors: Tokhanbigli Samaneh , Haghi Mehra , Dua Kamal , Oliver Brian Gregory George
Published: September 2024

Cancer-associated fibroblasts (CAFs) are the vital constituent of the tumor microenvironment, and in communication with other cells, they contribute to tumor progression and metastasis. Fibroblasts are the proposed origin of CAFs, which are mediated by pro-inflammatory cytokines and the recruitment of immune cells akin to wound healing. Although various studies have identified different subpopulations of CAFs in lung cancer, the heterogeneity of CAFs, particularly in lung cancer, and their potential as a therapeutic target remain largely unknown. Notwithstanding CAFs were previously thought to have predominantly tumor-promoting features, their pro- or anti-tumorigenic properties may depend on various conditions and cell origins. The absence of distinct markers to identify CAF subpopulations presents obstacles to the successful therapeutic targeting and treatment of CAFs in cancer. Human clinical and animal studies targeting CAFs have shown that targeting CAFs exacerbates the disease progression, suggesting that subpopulations of CAFs may exert opposing functions in cancer progression. Therefore, it is essential to pinpoint specific markers capable of characterizing these subpopulations and revealing their mechanisms of function. The cell-specific surface markers of CAFs will serve as an initial step in investigating precise CAF subpopulations and their role in diagnosing and targeting therapy against cancer-promoting CAF subsets in lung cancer.

Published: September 2024

The objective of our study is to examine the influence of combined performance measurement systems (PMS), which include both subjective evaluation and objective measures, on the willingness of employees to share knowledge. Additionally, our study investigates another variable which may influence subjective judgments of employee performance, namely supervisor trustworthiness. We argue that incorporating subjective evaluations into a performance measurement system will have little effect on knowledge-sharing behavior unless the supervisor is considered trustworthy enough to evaluate such behavior. Using a 2x2 between-subjects experiment design with 73 undergraduate students who act as employees as subjects, the result of this study shows that including subjective evaluation in a PMS encourages the willingness to share knowledge more than only using objective measures. This study also shows that supervisor trustworthiness alone can encourage a willingness to share knowledge. Furthermore, the combination of PMS which include subjective and objective measures and high supervisor trustworthiness has a significant impact on increasing the willingness to share knowledge.

Authors: Octavio Muhammad Fadhly Rizky , Falikhatun
Published: September 2024

This Study explores the effectiveness of Enterprise Resource Planning (ERP) business simulation games on user competencies. This Study Uses a qualitative descriptive methodology, and the informants of this research have been winning in national and international business simulation games (both students and alums). Traditional pedagogical approaches need to be revised to explain the rich dynamics arising from business environments. As a result, they also consider incorporating new educational aids into their curriculums, i.e., business simulation games. Participants indicated that interacting with these simulations enhanced their understanding of business topics and resulted in soft skills growth. Current working alumni said they felt more capable of acclimating to the professional world. However, the Study unearthed that comparatively few higher education institutions incorporate business simulation games in their teaching practices. The result shows that with the development of technology, there is a transformation in how business functions; integration of these tools into educational frameworks becomes essential to narrow the knowledge theory gap and knowledge application. These results suggest the importance of universities introducing technology tools, particularly ERP business simulations, into their curricula for Business and Economics courses (single or joint honors) alongside accounting.
Cauda equina syndrome successfully treated with microdiscectomy and methylprednisolone therapy: A case report
Authors: Henderson Alhoi Hendry , Ibrahim Sabri
Published: September 2024

Cauda equina syndrome (CES) caused by lumbar disc herniation is a rare neurosurgical emergency in young adults that requires immediate decompression. A surgical delay over 48 hours may result in irreversible ramifications, underscoring a crucial timeframe for managing this condition. We presented a 26-year-old man with lower limb weakness persisting for one week, accompanied with exacerbating bowel and bladder issues after massage. The patient had a history of low back pain and tingling sensations radiating to the left leg over the past year. His physical examination showed right motor strength of 5/4 and left motor strength of 5/3, with weakened bowel peristalsis, loose anal sphincter and saddle anaesthesia. A spinal MRI revealed protruded discs extending to the intervertebral levels of L4-L5 and L5-S1, implicating herniated discs as the likely cause of CES. He underwent a microdiscectomy with a posterior approach, and intravenous methylprednisolone was administered before the procedure. The next surgery demonstrated enhancements in motor strength, bowel and bladder function, and it also reduced pain. He was discharged with persistent tingling sensations in his both legs. We concluded that CES represents a critical neurosurgical emergency, which is diagnosed through clinical symptoms and neuroimaging. Rapid decompression and intravenous administration of methylprednisolone are associated with better prognosis.

Authors: Kuntari Titik , Supadmi Sri
Published: September 2024

Background: The prevalence of anemia among pregnant women in Indonesian remains high at 48.9%, with the highest rates observed among young mothers aged 15-24 years. Anemia is associated with adverse outcomes for both mothers and their children. Understanding the determinants of anemia in young mothers is crucial for taking preventive measures. However, there are currently no national studies in Indonesia on the prevalence and risk factors of anemia in pregnant women aged 15 to 24 years.Objective: To measure the prevalence and factors associated with anemia in young pregnant women in Indonesia.Methods: This cross-sectional study utilized on secondary data from the 2018 Basic Health Research (Riset Kesehatan Dasar= Riskesdas). The subject of this research were pregnant women aged 15 to 24 years who participated in Riskesdas 2018 and had independent variables data including hemoglobin measurement data, age, education, residence, occupation, travel time to health facilities, age at first pregnancy, ownership of the maternal and child health (MCH) handbook, history of previous abortion, gestational age, number of iron supplement tablets, supplementary feeding, and chronic energy deficiency. Univariate analysis was conducted to analyse the subject characteristics and hemoglobin data, while chi-square and logistic regression were used to determine factors associated with anemia in young pregnant women Results: The study found that 36.2% of young pregnant women had anemia. The incidence of anemia was associated with gestational age but not with other factors. Pregnancy in the first trimester poses the highest risk compared to other trimesters (cOR=3.89; 95%CI:1.47-10.30; p=0.006), as confirmed by multivariate analysis (aOR=4.44; 95%CI: 1.41-13.95; p=0.01).Conclusion: Anemia affects 36.2% of pregnant women aged 15 to 24 years in Indonesia. The risk of anemia in young pregnant women is significantly associated with gestational age with the first trimester being the most critical period.

Published: September 2024

Background: Breast cancer is the most frequently diagnosed cancer in the world, approximately 2.3 million new cases (11.7% of all cancer cases) per year in 2020. The Ki-67 expression is clinically used to classify molecular subtypes of breast cancer into luminal A and luminal B groups.Objectives: This study aimed to investigate relationships between clinicohistopathological characteristics (ages, histopathological types, histopathological grades, molecular subtypes) of breast carcinoma patients and the Ki-67 proliferation index at dr. Moh. Hoesin General Hospital (RSMH) Palembang in 2019–2021.Method: This study applied an observational analytic study with a cross-sectional approach. 521 samples were included in this study based on inclusion and exclusion criteria. The samples in this study included invasive breast carcinoma patients who underwent histopathological examination and immunohistochemistry (IHC), recorded in the medical records at RSMH Palembang for 2019–2021 period. Then a statistical analysis was performed by using the chi-square test, which was analysed in the SPSS application.Results: The correlation between Ki-67 proliferation index and histopathological grades was statistically significant (p=0.018). The Ki-67 proliferation index was also statistically significantly associated with the molecular subtypes (p=0.000). Neither age (p=0.315) nor histopathological types (p=0.417) were significantly associated with the Ki-67 proliferation index.Conclusion: The Ki-67 expression was significantly associated with histopathological value and molecular subtype in breast carcinoma patients at RSMH Palembang in 2019–2021. The Ki-67 expression was not associated with the clinic-histopathological characteristics of ages and histopathological types.
