The research focuses on the validity and reliability of a love language questionnaire tailored to the Indonesian context, where cultural nuances play a significant role in interpersonal relationships. The sampling technique in this study used a non-probability sampling method to determine the sample tested, where the population was married individuals in the Bone district. Therefore, the technique chosen was the purposive sampling method. Hence, this research consisted of 30 married individuals from the Bone district. A triangulation approach was applied to develop the questionnaire, combining linguistic analysis, psychological insight, and statistical rigor. This method ensured that the questionnaire captured the nuances of love languages in the Indonesian context. The Love Language Questionnaire was grouped into five indicators: acts of service, receiving gifts, quality time, words of affirmation, and physical touch. Each indicator consists of four positive and four negative statements. The type of analysis employed was inferential analysis. The analysis results revealed that 30 items scored above the Pearson correlation coefficient of 0.361, indicating the validity of the items. In addition, Cronbach's alpha coefficients for all indicators exceeded 0.70, indicating reliability. The results indicate that the questionnaire is a valid and reliable instrument for research in psycholinguistics. The limitation wall that hindered the results was the lack of a proper understanding of the sociolinguistic nature of the research population.
Commercialization of Higher Education, Challenges of Education System in the Era of Technology 4.0
Authors: Irlina Andi , Iqbal Noor Muhammad , Elli Elli
Published: July 2024

Commercialization of Higher Education has become an increasingly dominant issue in the educational system in the era of Technology 4.0. This article attempts to identify the changes in the higher education paradigm caused by commercialization, including rising educational costs, profit, and influence on the curriculum. Additionally, the article examines the impact of commercialization on higher education, the challenges it faces, and ways to overcome the existing barriers. The research conducted a literature review. The writer uses documents such as journals, books, and online media as data sources. The collected data was analyzed using content analysis methods. This research reveals that the commercialization of education is a deliberate system created by both governments and investors. The government minimizes the government budget expenses by changing PTN to PTN-BH. At the same time, the investors try to optimize their profits from educational institutions without considering the achievement of educational goals. On the other hand, the commercialization of education reflects that education is treated as a commodity. However, it must be acknowledged that the commercialization of education has both positive and negative impacts. Therefore, efforts to mitigate the commercialization of education that can serve as a solution are needed. In this regard, the government, as the education decision maker, must regulate higher education quality and ensure broader accessibility. This requires a balanced approach between the commercial needs of universities and the interests of the public in providing quality education. Additionally, higher education must continue adapting to Technology 4.0 to maximize the potential for more inclusive and relevant education while maintaining the integrity of education and Islamic values.

Penerapan Algoritma Taboo Codes Pada Kompresi File Text
Authors: Yuni Intan Hutagalung Naomi
Published: July 2024

The needs of modern humans and the demands of technological developments today force every individual to work a lot on computers and use all digital data, requiring everyone to use a text file manager application such as Microsoft Office to process a conventional text into a digital text file. This is because files in digital electronic form are preferred over conventional forms, due to certain factors such as data security problems, ease of processing, distribution and modification of data. The tendency of humans at this time to collect data in the form of text files and documents on a computer causes storage media on computer devices to run out faster. Moreover, at this time most individuals share text files using internet media via email or social media such as WhatsApp and telegram, meanwhile the very slow internet network in Indonesia causes the sending of large text files to take a very long time. The Taboo Codes algorithm has an approximation to the length of a variable. The initiator of the Taboo Codes Algorithm is Steven Pigeon, the principle of the Taboo Codes Algorithm, which is to select positive n numbers and reverse the n pattern to indicate the end of the code, the taboo codes algorithm works to compress text files by replacing the original binary value of each character into a binary value. The taboo codes algorithm is shorter, so compressing a text file using the taboo codes algorithm can reduce the original text file size by about 20%.

Outcome of Midwife-Led Debriefing on Postpartum Depression in Western Region, Kenya
Authors: Oronje Sally , Kipmerewo Mary , Okoth John
Published: July 2024

ABSTRACT
Context: Giving birth is a traumatic experience for women, and if unresolved, the emotions it causes can have a lasting negative impact on mental health, including depression in the postpartum period. Depression is a prevalent mental illness that can have major repercussions, particularly after giving birth. There is evidence of postpartum depression. However, many studies have concentrated on the prevalence of postpartum depression. In middle-income countries, including Kenya, very few studies have assessed the outcome of midwife-led debriefing for the prevention of postpartum depression. 
Aim: The study aimed to assess the outcome of a midwife-led debriefing on postpartum depression in the Western region of Kenya.
Methods: The study was a quasi-experimental design with pre and post-test assessments. The study used the postnatal register as the sampling frame. Systematic random sampling was used to identify and allocate participants to the study's intervention and control groups. The target population was women of childbearing age. The study participants were women who gave birth during the study period, of which a sample of 212 participated in the study. The 165 participants were allocated to the intervention group, while 47 participants were in the control group, based on the 22% Prevalence of Postpartum Depression (PPD). Data was collected using a structured questionnaire on demographic characteristics and the Edinburg Postpartum Depression Scale (EPDS) for assessment of postpartum depression level.
Results: The study results show that midwife-led debriefing significantly reduced the symptoms of postpartum depression (t=14.672, p-value=0.003). The Odds ratio (OR= 5.41) indicated an association between the intervention of midwife-led debriefing and the outcome (Reduced symptoms of depression) as compared with the standard care. The coefficient of β=0.871 shows a proportional shift in postpartum depression prevention of 0.871 units for every unit increase in midwife-led debriefing. At the 5% significance level, the null hypothesis was rejected (p=0.003), suggesting that postpartum depression could potentially be prevented using midwife-led debriefing.
Conclusion: Midwife-led debriefing reduces postpartum depression symptoms. The study recommends that the national and county government health systems integrate midwife-led debriefing into the standard practice for postpartum care.

Authors: Lekha Tuli Lekha Tuli , Shariq Mohd , Patawa Rohit
Published: July 2024

Background: The COVID-19 pandemic has significantly affected the healthcare system. RT-PCR has played a major role in the confirmation of SARS-CoV-2 thus helping in an early diagnosis, clinical interventions and patient isolation. This study was conducted to ascertain the importance of RT-PCR testing among symptomatic and asymptomatic cases in different age groups with association to infection. 
Methods: This retrospective cohort study was conducted from August 2020 to August 2021, in the Department of Microbiology, Autonomous State Medical College and Sarojini Naidu Memorial Hospital, Firozabad, Uttar Pradesh, India. Samples were collected from a total of 342, 281 cases which comprised of symptomatic patients (ILI, SARI), asymptomatic contacts, those seeking hospitalization, travelers and were subjected to testing by RT-PCR. The cases were divided into group A of patients presenting with symptoms ≤7 days, group B of patients with signs and symptoms >7 days and group C comprised of asymptomatic cases. The symptoms of patients were associated with the Ct values of the E/N screening gene and the RdRp/ORF1ab confirmatory genes. The Chi-square test was done to test the statistical significance of association of symptomatic patients with the outcome of the test.
Results: The number of positive samples were 4,342 showing a prevalence of 1.3%. The maximum prevalence of infection was found in the age group of 20-29 years followed by the age group 30-39 years (p-value <0.05). The maximum positivity and high viral load were seen in the patients who presented with symptoms ≤7 days with Ct values ≤25.
Conclusion: The maximum infection was found in the young age group. The screening and confirmatory genes could be detected in the samples of asymptomatic cases also which was helpful in isolating them and breaking the chain of further spread of the virus.

Background: Over the past two decades, laparoscopic surgeries have significantly progressed, and surpassing traditional surgical methods across multiple medical fields. This study aims to assess the patients’ satisfaction and the related factors toward the laparoscopic cholecystectomy in Iraq.
 
Methods: A cross-sectional study was conducted from April 2023 to 30th March 2024 at the Alkalis General Hospital and Al Hayat Private Hospital, Diyala province, Iraq. Semi-structured questionnaire was recruited to collect the pre and post operative data from patients. Statistical analysis was carried out using SPSS-21, with significance set at p < 0.05.
Results: Data of 157 patients with mean age (+ Standard Deviation) of 47.57 (SD +12.80) were analyzed. Most of them (53.5%) were females, operated in public hospitals (52.2%), unemployed (51.6%), and earned less than USD 400 (60.5%). The majority of patients expressed high overall satisfaction with the laparoscopic cholecystectomy procedure (42.7% being strongly satisfied and 38.9% satisfied). In the multiple logistic regression, the patients who were operated in private hospital (OR = 4.506, 95% CI: 1.394 to 14-577; P-value= 0.012), with monthly income exceeds USD 400 (OR = 4.887, 95% CI: 1.531 to 15.601; P-value=0.007), involved in the choosing of surgery technique (OR = 5.596, 95% CI: 1.425 to 21.982; P-value=0.014), and those recommend laparoscopic cholecystectomy for others (OR = 9.100, 95% CI: 1.425 to 21.982; P-value=0.001), had the highest odds ratios. The Hosmer and Lemeshow test indicated a good fit (p = 0.552).
Conclusion: Patient satisfaction is high especially among high income patients operated in private hospital however, the perception of postoperative outcomes remains important areas of focus, particularly in regions with unique healthcare challenges like Iraq.

This study aims at analyzing the forms, functions, and meanings of humor used by preachers in delivering religious sermons. This study uses a qualitative descriptive method that focuses on the act of identifying, classifying, analyzing data that has been obtained, and describing it in the form of language as it is. Qualitative research emphasizes the depth of data with the researcher as a key instrument in the research. The research data consists of humorous utterances delivered by preachers in Islamic religious sermons, namely Ustadz Anwar Zahid, Ustadz Wijayanto, and Ustadz Da'as Latif. The form of humor is analyzed using morphosyntax theory, the function of humor is linked to sociolinguistic theory, while the meaning of humor is dissected using semantic and pragmatic theory. The results of the study show that there are five dominant forms of humor that appear in dakwah humor, namely line humor, dialogue, stories, poems, and wordplay. The use of humor as a strategy in dakwah is proven to be effective in achieving its communicative goals. Humor helps make religious messages easier to understand and remember by the audience. This is because humor can simplify complex concepts and make them more interesting for listeners. This study also found that humor is not only a form of entertainment, but also an effective communication tool in spreading religious teachings.

Biliary ileus is an unusual cause of intestinal occlusion in the general population (<5%), secondary to the impaction of a biliary stone in the digestive tract due to the presence of a bilioenteric fistula, a rare complication of cholelithiasis. A 65-year-old woman with intestinal occlusion secondary to biliary ileus, diagnosed by abdominal computed tomography, underwent open enterolithotomy. Post-surgery, the patient's symptoms resolved without complications. The treatment objective for biliary ileus is to relieve the obstruction, typically through enterolithotomy, although there is no definitive standardized surgical technique. This case report includes a brief literature review.

Published: July 2024

The objective of this study was to analyze the efficiency of goalkeeper in anticipation and preparatory posture during the 2018 FIFA World Cup. By analyzing video footage of official matches, we examined 669 shots taken throughout the competition. For each shot, we collected data on the goalkeeper's position (considering their preparatory posture and anticipation) and the outcome of the action (save or goal). Preparatory posturing was present in nearly all shots (n=611; 91%), while anticipation positioning was less frequently used (n=409; 61%). We did not find a significant association between preparatory posture and the outcome of the action (x²=1.333; p=0.248). However, we did find a significant and moderate-sized association between anticipation positioning and the outcome of the action (x²=71.49; p<0.001). In this situation, actions involving anticipation led to more goals conceded. Based on our findings, without taking into consideration the shooting situation, anticipation seems to have been less efficient in defending goals. These findings are important for coaches to incorporate into the training process to enhance the chances of success during matches.

Intensity level in crosstraining sessions in obese women: a real-world study
Authors: Vitor Schmals Silveira João , Souza de Souza Alex Sander , De Moraes Siqueira Gabriel , Boscolo Del Vecchio Fabricio
Published: July 2024

Objective: The objectives were to measure psychophysiological responses during crosstraining sessions in obese women, focusing on heart rate (HR), blood pressure (BP), caloric expenditure, and perceived effort (RPE). Additionally, it examined the relationship between caloric expenditure and effort intensity. Methods: This real-world observational study involved ten obese women (average age: 31.5 ± 6.2 years, BMI: 34.2 ± 3.7 kg/m², crosstraining experience: 5.3 ± 3.4 months). Participants underwent three individual crosstraining sessions. Each session's training type and duration were recorded. BP was measured before and after, along with HR at rest, average HR, peak HR, and RPE post-workout. Internal load and caloric expenditure were calculated. Results: Among 30 observed sessions, there were no significant differences in training duration by type. Caloric expenditure averaged 272.3 ± 76 kcal. Systolic BP increased significantly (from 129 ± 8 mmHg to 160 ± 16.5 mmHg), as did diastolic BP (from 90.3 ± 6.7 mmHg to 113.6 ± 14.9 mmHg, p < 0.001). Mean HR was 136.9 ± 14.8 bpm (73.6 ± 7.3% of HRmax), and peak HR reached 181.9 ± 12.1 bpm (97.8 ± 6.1% of HRmax). Participants spent more time at or above 80% of predicted HRmax. Mean RPE was 5.7 ± 2.2 a.u., significantly correlating with exercise time above ≥90% of HRmax (r = 0.37; p = 0.046, effect size = 0.39). Conclusions: Crosstraining sessions in obese women raised BP, induced high caloric expenditure, and imposed significant cardiorespiratory demands, classifying these sessions as high-intensity. This intensity closely correlates with energy expenditure.

The school context embodies the optimal environment for educating children towards the adoption of active lifestyles. This is auspicious not only in terms of physical health but also from a psycho-pedagogical and social standpoint. The need to integrate physical activity into the school routine, particularly in primary education, where behaviors are established and carried on into later stages of life, emerges clearly from the scientific literature. Health education sessions with a focus on preventive measures can be organized by the school’s medical services for the benefit of students. It is imperative within educational practices to view the motor domain as a crucial instrument for instilling appropriate lifestyles, enhancing cognitive growth, fostering inclusivity, and addressing psycho-emotional and socio-relational aspects. The school environment can significantly contribute by serving as a pivotal setting for promoting physical activity throughout various periods of the day. Movement can be incorporated into teaching activities, and active breaks can be integrated into class hours, either before or after lessons. This study stems from a comprehensive examination of the existing literature regarding the correlation between the school environment, health, and preventive health promotion. It recognizes the ongoing nature of the issue and the need for further investigation to align with forthcoming changes.
