The main objective of this research is to examine the influence of the causes of entrepreneurial failure by using two types of causes of entrepreneurial failure (internal causes and external causes) on learning from entrepreneurial failure and its impact on the performance of SMEs in DKI Jakarta. The research method used in this research is a quantitative research method using a survey with the analytical tool used, namely Smart PLS version 3.0. which aims to examine the variables that cause internal failure, the causes of external failure, learning from entrepreneurial failure and its impact on business performance variables. The research results show that the variable learning from failure has a significant positive effect on business performance. Likewise, the variables that cause entrepreneurial failure from internal factors have a positive and significant effect on learning from entrepreneurial failure. However, in contrast to the results of testing variables that cause failure from external factors on learning from entrepreneurial failure, it shows that there is no influence on the causes of entrepreneurial failure from external factors on learning from entrepreneurial failure. It is hoped that this research can provide suggestions and input, especially for SMEs, so that they can turn entrepreneurial failures into lessons to improve business performance. This research also has several limitations, including that the SME business sector in this research is still too general, and this research only uses subjective performance measures.

Published: October 2024

The harmonious relationship between humans and their environment can be likened to a mutually beneficial relationship. This perspective views humans as an inseparable element of their environment, with an emphasis on the human obligation to care for and ensure the survival of nature. In return, nature will provide benefits to fulfil human needs. This research aims to actualise ecological verses in human life and produce the proposition of theological insanity from the perspective of the Quran. The following research method is a qualitative approach focusing on library research. As a guide and reference, it uses library data sources. When viewed from the method of analysis, it can be classified as descriptive research that describes information based on events and facts and relates it to explanations from related sources according to the topic of this research. In analysing Quranic interpretation, the following includes thematic or maudhûi interpretation research, with steps, namely collecting Quranic verses related to humans, the environment and nature. Furthermore, it provides interpretation and understanding of the verses in question through the application of various contemporary interpretation sources combined with other sources. This research produces a proposition of ecological human character in the Quran, which includes Khalifah, Hikmah, and Mizan. Thus, three things are interrelated to create the character of the rahmatan li al 'alamin people.

Published: October 2024

This study explores the relationship between self-compassion, perceived social support, academic stress, and mental well-being among Fast Track students at UIN Malang. Adopting a quantitative approach, the research employs a correlational design to examine the interactions of these variables in a high-pressure academic environment. Data were collected from a 61% sample of Fast Track students using a structured questionnaire, incorporating validated scales for self-compassion, social support, academic stress, and mental well-being.  The findings reveal that Fast Track students generally exhibit high self-compassion, significantly correlated with their mental well-being. High levels of self-kindness, mindfulness, and an awareness of shared humanity were prominent among the students, suggesting a solid psychological resilience. Perceived social support from family and friends significantly impacted overall well-being, though its direct influence on academic stress was more complex. The research did not find a significant direct relationship between self-compassion and academic stress, indicating that self-compassion aids in managing emotional responses to stress rather than reducing it.The study underscores the need for a holistic approach to supporting students in accelerated academic programs. The findings suggest that enhancing self-compassion and strengthening social support networks can improve students' academic performance and mental well-being. This research contributes to understanding students' psychological dynamics in high-pressure academic settings. It provides insights for developing targeted interventions and support systems to foster a balanced and supportive educational environment.

Published: October 2024

The activity of every enterprise is constantly accompanied by challenges and threats from both the internal and external environment of its functioning. That is why effectively established processes are often a guarantee of its success and sustainability. The reengineering of business processes itself is the tool that allows you to significantly improve your work, due to a radical reassessment and transformation of the main business processes. This tool aims to achieve improvements in key indicators such as costs, quality, service and speed. The article establishes the relevance of transformations in business processes using reengineering. A retrospective of the evolution of approaches to reengineering was conducted. The experience of using it to improve the performance of the business giant Ford is presented. It has been determined what advantages enterprises receive from the reengineering of business processes. The main stages of reengineering are grouped: mapping the current state of business processes, analyzing them and identifying gaps, finding opportunities to improve business processes and their verification, developing a process map of the future state and implementing future changes. It was determined that these stages may vary depending on the specifics of the enterprise's activities. The principles of effective reengineering are presented, according to Hammer M. and Champy J. Modern business process reengineering tools are specified: IT, change management, value chains, benchmarking, model change, monitoring, active accounting, GAP analysis, Lean and Six Sigma, Business Process Management, design thinking and modeling and stimulation. Systematized recommendations for increasing the efficiency of the reorganization process, in particular, using only proven methodology, documenting the reasons for introducing changes, analyzing business needs, taking any actions taking into account the priority of customers, as well as effective change management. Further prospects of research in the chosen direction are outlined, taking into account the achievements of artificial intelligence.

Authors: Düzen Cem
Published: October 2024

Osmanlı Devleti’nin XVIII. ve XIX. yüzyılları, farklı kategorilerde tasnif edilen isyan hadiselerinin birbiri ardına patlak verdiği bir zaman aralığıdır. Bu isyan hadiselerinin en önemlilerinden birisi ise kuşkusuz 1791-1808 yılları arasında etkinliğini sürdüren dağlı isyanlarıdır. Kırcaali’de ortaya çıkan ve önü alınmaz bir şekilde Rumeli’nin her noktasına sirayet eden dağlı isyanları, tarihi çalışmalara araştırma konusu olan muhtelif isimleri miras bırakmıştır. Bu isimlerin en önemlilerinden biri de Manav İbrahim’dir. Manav İbrahim, dağlı eşkıyasının Rumeli’de etkin bir şekilde faaliyet gösterdiği zaman aralığı referans alınırsa nispeten kısa bir süreliğine adından bahsettirmiştir. Ancak kısa süreli etkinliğine rağmen Manav İbrahim’in yaşamı, dağlı eşkıyasının hangi iç dinamikler çerçevesinde türediğine ve faaliyet sahasını nasıl genişletebildiğine dair cevaplar barındırmaktadır. Bu bakımdan Manav İbrahim’e dair yapılan bir araştırma dağlı eşkıyasının profilini okumaya yardımcı olurken aynı zamanda Rumeli’de yaşanan kaotik döneme de ışık tutmaktadır. Bu çalışmada bir dağlı eşkıyası olarak tarihe mâl olan Manav İbrahim’in faaliyetleri kronolojik olarak değerlendirilmektedir. Bu minvalde cephede savaşmak üzere Anadolu’dan Rumeli’ye getirilen bir askerin zamanla nasıl eşkıya reisine dönüştüğü bilimsel veriler doğrultusunda incelenmektedir. Bu bağlamda Cumhurbaşkanlığı Osmanlı Arşivi ise çalışmaya dair temel referans noktası olmuştur.

Published: October 2024

Türkiye-Yunanistan iki komşu ülke, geçmişten günümüze aralarında kimi zaman savaşlar, krizler, gerginlikler yaşanmış, kimi zaman da yumuşama süreçlerine girilmiş ilişkiler dalgalı bir seyir izlemiştir. Türk-Yunan ilişkilerinde yaşanan sorunlar birbirinden bağımsız değildir. Uyuşmazlık sebepleri arasında Ege Denizi kaynaklı sorunlar bunların başında gelmektedir. Bu çalışmanın odağında denizel kaynaklı bir sorun olan “Gayrı Askeri Statüdeki Doğu Ege Adalarının Silahlandırılması” konusu yer almaktadır. Türkiye’ye yakın olması ve Türkiye’nin güvenliği açısından Doğu Ege Adaları, gayrı askeri statüde olması koşuluyla Yunanistan’a devredilmiştir. Söz konusu adaların devriyle ilgili olarak Ege Denizi’ndeki dengeler 1923 Lozan ve 1947 Paris Barış Andlaşmaları ile sağlanmıştır. Ancak 1950’li yıllarda iki ülke arasında patlak veren Kıbrıs sorunuyla birlikte Ege’de dengeler değişmeye, Yunanistan adaları silahlandırmaya başlamıştır. 1974 Kıbrıs Barış Harekâtı’nın ardından ikili ilişkiler daha da gerilmiş, Yunanistan Türkiye’den tehdit algıladığını ileri sürerek tek yanlı eylemleriyle uluslararası andlaşmaları ihlal etmeyi ve adaları silahlandırmayı sürdürmüştür. Halen bu faaliyetlerini Türkiye’nin de NATO’dan müttefiki olan Amerika Birleşik Devletleri’nin sağladığı silah desteğiyle sürdürmektedir. Bu çalışmanın amacı, 1950’li yıllardan günümüze dek süren ve iki ülke arasında uyuşmazlık sebebi olan adaların silahlandırılması meselesini her iki ülkenin resmi tezleri ışığında ve farklı yönleriyle analiz etmektir.

Published: October 2024

Machine learning has disrupted enterprises and business analytics. This has brought a shift from reliance on standard statistical techniques to a scientific approach where models depend on the available data. This paper assesses how ML packages could be used in diverse business settings with more focus on Random Forests and Neural Networks. The outlined models are assessed against linear and logistic regression models, and the distinction is made using accuracy, ROC curves, and precision-recall evaluative metrics. The study shows that even at 88% accuracy rate Neural Networks clearly outperform traditional methods and performing this task in the American business environment. It was also found that Random Forests can outperform 85% of the simple methods. The results also show that these metrics can be modified to achieve further efficiency. The application of those models showed improved performance metrics specifically in ROC and precision-recall curves. The study findings relevant to the domains of ML explain the effectiveness of combining batch size and learning rate optimally to achieve high accuracy rates in Neural Networks, e.g., 90%. Some suggestions for future work describe work needed to improve the explainability and ethics of the model while making it as usable as possible for businesses.

Published: October 2024

The integration of machine learning (ML) into health information technology (HIT) is revolutionizing data-driven healthcare systems, yet several key challenges and areas of focus remain. Electronic health records (EHRs) constitute most of the data source (60%), with wearable devices and interviews/focus groups comprising smaller portions. This indicates a continued reliance on traditional health records, although emerging technologies are beginning to play a role. Another key preprocessing challenge, with data cleaning consuming the most effort (40%), followed by data anonymization and feature selection, each requiring substantial effort in ensuring the accuracy and privacy of patient data. Supervised learning dominates in healthcare applications, followed by deep learning and unsupervised learning. In terms of accuracy, EHR data consistently yields the highest performance, around 85%, closely followed by wearable devices, genetic data, and lifestyle data. However, challenges remain in addressing data privacy and algorithm transparency, as highlighted by the distribution of effort in ensuring compliance and maintaining data privacy. The findings suggest a need for further exploration into wearable devices and the real-time monitoring capabilities they bring to healthcare, alongside tackling data preprocessing and ethical challenges in HIT.

Published: October 2024

The study aimed to estimate oil spillage in the Kokori Oil Field, discovered in 1958, using a linear model. The field has 23 oil wells and produced 383 million barrels of oil. A linear model was developed using Python programming, comparing it with the trapezoidal method and salvage revenue. Results showed a linear relationship between oil spill quantity, duration, and mitigation measures. This study provides a valuable model for estimating oil spillage in the Kokori oil field, emphasizing the importance of accurate estimation for environmental and economic purposes. The study presents a comprehensive model for estimating oil spillage in the Kokori oil field, emphasizing the significance of accurate estimation for environmental and economic purposes. The correlation coefficient value supports the model's sufficiency, and the calculated salvage revenue indicates a commendable projected value for the Kokori oil field at its end of use. Salvage revenue is the estimated value of an asset at the end of its useful life, which is crucial in determining the cost of goods sold and depreciation charge. It lowers the asset's cost, influences its usable life, resale value, and replacement cost. Salvage revenue is calculated by subtracting revenue generated without mitigation measures from revenue realized with mitigation measures.

Close Encounters of the Archival Kind: Affect and Transnational Solidarities in African Diaspora Archives
Authors: Ashie-Nikoi Edwina Dei
Published: October 2024

Recent explorations of affect in the archives have focused on the experiences of users and particularly the distress archival collections could possibly cause them. Perhaps because they have, until recently, been trained to think of themselves as engaged in objective and neutral work collecting and preserving memory, archivists rarely reflect on or talk about their work, how they engage with the materials they manage, and how they personally feel about what they encounter in the course of their professional lives. Using an autoethnographic conceptual framing, this article uses four archival encounters in the Manuscripts, Archives and Rare Books Division of the Schomburg Center for Research in Black Culture to reflect on affect in the archives invoked by archival work. Through these encounters, the article seeks to demonstrate archives of the African diaspora as both a locus of transnational African diasporic identities and solidarities, as well as a critical site for the (re)building of the same. Finally, it also hints at how such affective experiences can, in fact, further the cultural and political work of Black archivists and archives.

Published: October 2024

Background: Polycystic ovary syndrome (PCOS) is an emerging endocrine condition that affects women of reproductive age all over the world. Physical activity (PA) is an evidence-based approach in the management of PCOS patients.
Methods: This hospital-based case-control study was conducted to find out the association between physical activity and obesity with PCOS among the conveniently selected 172 women.
Results: The mean age of PCOS women was 25.0±5.8 years and non-PCOS women was 28.1±7.5 years. The majority of cases (84.9%) were in the 15-30 age groups, in comparison to controls (64.0%). There was a significant association between age and PCOS (p<0.05). The chance of developing of PCOS was 3.1 times higher in the younger age group. More than half of cases (65.5%) had no child, in comparison to controls (72.4%) had a child. There was a significant association between the number of children and PCOS (p<0.05). The chance of infertility among PCOS women was 2.01 times higher than among non-PCOS women. About one-third of the cases (39.5%) had a normal BMI and 37.2% were overweight. In contrary among controls, about half (59.3%) had a normal BMI, and one-fourth (25.6%) were overweight. The association between BMI and PCOS was statistically significant (p<0.05). The chance of developing of PCOS was 3.38 times higher in overweight women. The mean total sitting time/week in PCOS women (3179.76±1511.46) was higher than in non-PCOS women (2647.67±1687.74). There was a statistically significant association between total sitting time and PCOS in women (p<0.05).
Conclusion: There was a significant association between PCOS and BMI, indicating that overweight women are at greater risk to develop PCOS. However, no association was found between physical activity and PCOS, whereas PCOS patients sitting longer per week.

Background: The novel corona virus disease 2019 (COVID-19) is major public health issue. It is the most significant global health challenge in the world. Biomarkers play a significant role to detect the severity of COVID-19 infection in the perspective of management of the patients.
 Aim and objective: We aimed to assess the association between the levels of C-Reactive Protein and D-dimer in COVID-19 patients.
Methods: This cross-sectional study was conducted in the department of Pathology and department of Microbiology GMCH, Khulna. 152 patients with SARS-CoV-2 (COVID -19) positive patients were enrolled in this study. C-reactive protein and D-dimer levels are measured in the laboratory of Pathology department, GMCH, Khulna. All statistical computations were performed by using window-based computer software devised with Statistical Packages for Social Sciences (IBM SPSS Statistics 21 version).
Results: In this study CRP level was found of mean value of 62.84± 44.64 mg/L with a range of 1.40-195.20 mg/L. It was normal in 21 (13.8%) patients and increased in in 131 patients (86.2 %). The mean value of D-dimer was 2.48 ± 02.20 mg/L with a range of 0.10-9.35 mg/L. D-dimer was normal in 26 (17.1%) patients, whereas it was increased in 126 patients (82.9 %). We performed Pearson’s correlation-coefficient (r) test to compare the association between the levels of CRP with D-dimer in COVID-19 positive patients. There was moderately positive and significant correlation (r = +0.647, p <0.05) between the levels of CRP and D-dimer.
Conclusion: There was statistically significant correlation between the levels of serum CRP with D-dimer in COVID-19 positive patients. These two biomarkers can be used to assess the severity in patients with COVID-19 positive with thrombotic disorder for reduction of morbidity and mortality of COVID positive patients.

Published: October 2024

Background: Acne vulgaris is a very common condition which can cause significant physical and psychological morbidity. Oral retinoids and tetracyclines have a major role in acne treatment. Isotretinoin (13-cis-retinoic acid) is the only therapy that impacts on all of the major aetiological factors implicated in acne. Another agent is lymecycline, a tetracycline antibiotic have an antibacterial action against P. acnes and also an anti-inflammatory action and used for treatment of acne.
Objectives: To determine the efficacy and safety of Isotretinoin capsules versus Lymecycline capsule in treatment of mild to moderate facial acne vulgaris.
Materials & method: This open labelled, randomized study was conducted in Department of Dermatology and Venereology, Dr. Sirajul Islam Medical College & Hospital Ltd., Dhaka, from December 2021 to May 2022. Patients of mild to moderate facial acne vulgaris were enrolled for study. Clinical examination and relevant investigation were done meticulously. A total number of 50 patients was selected and randomization was done 1:1 parallel design into two groups (group-A and group-B), each of which included 25 patients. Group A patients received Isotretinoin and group B patients were given Lymecycline. Patients were followed up on 2nd, 4th, 8th and finally on 12th week to see clinical improvement and adverse effects. All information was recorded in data collection sheet.
Result: The mean age was found 20.4±5.7 years in group A and 19.9±6.9 years in group B. The mean age difference was not statistically significant (p>0.05) between two groups. Male to female ratio was almost 1:3 in the whole study patients. Mean score for open comedone (0.28±0.22 vs. 2.2±1.13), closed comedone (1.92±0.19 vs. 2.08±0.25), papule (0.82±0.29 vs. 1.27±1.04) and pustule (0.85±0.33 vs. 1.19±0.39) was identical in group-A and B respectively and significantly better reduction of acne score (p=0.001) in the group A than the group B. It was evident that abdominal discomfort (4.0% vs. 32.0% in group A & B), diarrhea (0% vs. 16.0% in group A & B) and photosensitivity (4.0% vs. 16.0% in group A & B) was predominant in group B. The difference was statistically significant (p=0.029). Whereas, erythema and burning was predominant in group A. Mean burning was found 0.15±0.08 in group A and 0.11±0.05 in group B and mean scaling was found 1.27±0.98 in group A and 1.45±0.98 in group B which were statistically non significant (p>0.05) between two groups. At 4th follow up mean total safety score was found 3.05±0.92 in group A and 4.65±1.25 in group B.
Conclusion: Isotretinoin was as effective as lymecycline for the treatment of moderately severe acne vulgaris. Both treatments were well tolerated & effective.

Background: Lateral epicondylitis, is prevalent in the world of sports; however, this injury still causes confusion among healthcare professionals. Numerous studies have evaluated treatment options, but few have taken into consideration the extent to which tennis players, themselves, understand this ailment.
Objectives: To identify the risk factors associated with lateral epicondylitis.
Materials and methods: An observational case control study design was carried out among 120 patients attended at outdoor Department of Physical Medicine and Rehabilitation, BSMMU, Dhaka from April 2018 to march 2019. Sixty (60) patients with lateral epicondylitis as case group and another 60 patients without lateral epicondylitis as control group. Data was collected using a structured interviewer- administered questionnaire, enquiring about demographic data and details of risk factors.
Result: The mean age was found 39.4:6.3 years in case group and 36.97.4 years in control group. Twenty- seven (45.0%) patients had more than 2 hours of use hand in case group and 12(20.0%) in control group. More than half (53.3%) patients had moderate VAS scale in case group and 9(15.0%) in control group, Nine (15.0%) patients were found past history of recurrent injury in case group and not found in control group. The difference was statistically significant (p<0.05) between two groups. Patients having use hand more than 2 hours 3.273 (95% CI 1.453% to 7.36%) times more likely to developed lateral epicondylitis.
Conclusion: Use of hand with repetitive wrist extension more than 2 hours was significantly associated with lateral epicondylitis.

Published: October 2024

Background: Acne vulgaris is one of the most commonly found skin problems affecting teenagers and adolescents. Dietary foods particularly dairy products consist of milk or any of its food made from milk are frequently regarded by patients and clinicians as a cause or aggravator of acne. As there are very limited studies found on this regard, this study was aimed to find the association of dairy foods in acne vulgaris.
Methods: This wasa cross-sectional analytical study and was carried out in the Dermatology and Venereology department of Shaheed Suhrawardy Medical College Hospital. Total 260 patients were selected by appropriate inclusion criteria equally into two groups: Group A (diagnosed with acne vulgaris, n=130) and group B (patients not having acne vulgaris, n=130). A thorough history of every patient and face to face interview was taken by a predesigned questionnaire after getting the written informed consent of the patient. Data were collected in predetermined data collection form. Result were subjected to standard statistical evaluation and were analyzed by SPSS-24.
Results: According to the age group, majority of the acne patients were between 10-20 years (75.4% in group A and 63.8% in group B, p<0.05), though mean age in both groups were statistically similar (18.53±5.78 and 17.29±4.59 years, respectively). Also, female respondents were predominant in both groups (80.8% and 72.3%). The risk was increased in those with a family history of acne in siblings (OR2.449, p=0.021;95% CI,1.145-5.238) and the risk was reduced in subjects doing physical exercise. Papules (35.4%) and comedones (27.7%) were most common lesion and mostly found in forehead (74.6%) and left (68.5%) and right (63.1%) cheeks. According to global acne severity grading, majority had mild form of acne (83.1%) and use of cosmetics (43.8% vs. 30%), topical steroid (34.6% vs. 16.9%), taking fastfood (24.6% vs. 14.6%) and less water intake (36.9% vs. 18.5%) also significantly higher among acne patients. Multivariate regression analysis showed, dairy products such as whole milk (OR 1.984, p=0.022), chocolate (2.490, p=0.004), chips (OR 3.207, p<0.001), Pizza (OR 2.388, p=0.021) and red meat (OR 3.055, p=0.009) were significant risk for developing acne vulgaris. Also, whole milk (3.050, p=0.01), chocolate (3.817, p=0.004) and pizza (3.822, p=0.005) were independent risk factors for moderate to severe acne.
Conclusion:  This study found an association between high dairy product consumption and acne in adolescents, indicating that dairy consumption may be a contributing factor for developing acne vulgaris.

Published: October 2024

Background: The strategic reperfusion early after Myocardial Infarction trial and the French Registry of Acute Anterior ST segment elevation MI suggested that pharmaco-invasive strategy compares favorably with primary percutaneous coronary intervention (PPCI).
Objectives: To evaluate in hospital clinical outcome of patients with acute anterior ST segment elevation myocardial infarction undergoing Primary PCI and pharmaco-invasive PCI.
Methods: This cross sectional study was conducted in United Hospital, Dhaka. A total of 120 patients were studied. These patients were categorized into two groups. Those with acute anterior ST segment elevation MI who underwent primary PCI was denoted as group A (n= 55) and those with acute anterior ST segment elevation thrombolysed by streptokinase followed by PCI confined to pharmaco-invasive PCI was denoted as group B (n=65).
Results: Acute LVF was more in pharmaco-invasive group than in primary PCI group and was statistically significant (p= 0.032). 02 patients (3.6%) died in primary PCI group: one of which was due to ventricular fibrillation followed by asystole 3 hours after procedure and the other died
due to cardiac arrest 10 hours after the procedure. No major bleeding incidence was found in both groups.
Conclusion: Acute anterior ST segment elevation myocardial infarction patients receiving pharmaco-invasive treatment compared with the Primary PCI had higher incidence of acute LVF and no significant discrepancy was observed regarding bleeding events, death, stent thrombosis, arrythymia, heart block and cardiac arrest.

Published: October 2024

Background:  When the blood supply to a portion of the brain is blocked or diminished, brain tissue cannot get oxygen and nutrients, resulting in an ischemic stroke. This study aimed to investigate the prevalence of hyperglycemia and dyslipidemia among patients with acute stroke in a tertiary healthcare setting in Bangladesh.
Methods: This cross-sectional study was conducted from January 2022 to December 2022 at a tertiary healthcare facility in Bangladesh, focusing on patients with acute ischemic stroke. Data was collected through a face-to-face interview, and medical records were reviewed. The study included 40 patients with acute stroke, evidenced by clinical findings and a CT scan of the Brain. Written informed consent was obtained after proper explanation, and participants were free to refuse or withdraw at any point. Confidentiality and privacy were maintained.
Results: The majority of participants (37.5%) were aged 60-69, with more males (57.5%) than females (42.5%). Most (70%) lived in urban areas. Among the participants, 82.5% had hypertension, and 52.5% had diabetes mellitus. The mean of HbA1c was 7.6% and of triglyceride was 205.0 mg/dl.  Of the participants with acute stroke, 47.5% had extracranial carotid stenosis.
Conclusions: Nearly half of those who had an acute stroke also had diabetes, and four out of five had a history of hypertension. Among the patient hyperglycemia and dyslipidemia was common. Nearly half of those who suffered an acute stroke also experienced carotid stenosis. Consideration should be given to managing hypertension, DM, dyslipidemia, and carotid stenosis among patients with acute stroke.
