In this study, we attempted to fabricate N-polar GaN/AlGaN/AlN heterostructure FET by changing the thickness of the AlN layer. An Al-polar tiny-pit AlN layer and a polarity inversion method were used to grow N-polar AlN on vicinal sapphire via the metal-organic vapor phase epitaxy. The samples with an AlN thickness of up to 3.4 μm exhibited a crack-free surface. Additionally, the twist component of the crystal quality improved with an increasing AlN thickness. Consequently, the mobility, sheet conductivity, and surface flatness improved. The FET fabricated from the sample with a thicker AlN layer achieved a higher drain current of 279 mA mm−1 at a gate bias of V
G = 3 V.

New plasma sources are proposed to clean optical mirrors in diagnostic instruments of the ITER experiment considering RF discharges operating at low pressures (1–10 Pa) in inert gases. There are nearly twenty optical diagnostics where the front-end optical mirrors may require plasma cleaning. The mirrors vary in size and would need up to 400 W in the discharge to form ion fluxes capable of removing Be- and W-containing contaminants to restore the optical performance with tolerable damage to the mirror. The plasma sources suggested to clean contaminants include a vacuum matching circuit placed close to the mirror and a quarter wavelength band stop notch filter when mirror water cooling is needed. Long-term operation stability and cleaning homogeneity may employ a driving frequency variation to tune the circuit and a phase shift for RF voltages to clean two mirrors simultaneously. In this paper, the plasma sources based on 40 MHz RF discharge to clean first mirrors are studied experimentally for two ITER optical instruments: the Edge Thomson Scattering and the Visible Spectroscopy Reference System. Frequency tuning and phase shifting are studied in realistic configurations prototyping diagnostic port plug geometries.
Effect of gas injection pattern on magnetically expanding rf plasma source
Authors: Nakahama Yugo , Takahashi Kazunori
Published: August 2024

Argon gas is injected from a back plate having either a radial center hole or shower-patterned eight holes into a 13.3-cm-diameter and 25-cm-long radio frequency (rf) plasma source attached to a 43.7-cm-diameter and 65cm-long diffusion chamber under an expanding magnetic field, which resembles the magnetic nozzle rf plasma thruster. The source has a double-turn loop antenna powered by a 13.56 MHz rf generator at a maximum power level of ~2.8 kW in low-pressure argon, providing a plasma density of about 1018 m−3 in the source. A high plasma density and a slightly low electron temperature are obtained for the shower-pattered case in both the source tube and the diffusion chamber, compared with the center hole case, suggesting that the neutral density profile significantly affects the plasma density profile. This result will provide an improvement in the thruster performance by the gas injection pattern.
Poligami dalam Pandangan KH. Husein Muhammad

Published: August 2024

Berbicara soal poligami tidak ada habisnya, akan selalu menarik untuk dijadikan sebagai tema bahasan dalam tiap kalangan, pro dan kontra pada poligami dari berbagai kalangan selalu ada, Husein Muhammad dalam berpendapat bahwa poligami bukan praktik yang dilahirkan oleh Islam. Jauh sebelum Islam datang, tradisi poligami telah menjadi salah satu bentuk praktik peradaban patriarkis. Pernyataan Islam atas poligami dilakukan dalam rangka mengeliminasi praktik ini, selangkah demi selangkah, hingga kelak praktik tersebut tidak ada lagi. Dua cara dilakukan al-Qur’an untuk merespons praktik ini: mengurangi jumlahnya dan memberikan catatan-catatan penting secara kritis transformatif, dan mengarahkannya pada penegakan keadilan. Penelitian ini akan mengkaji bagaimana pandangan Husein Muhammad tentang konsep poligami dengan menggunakan bahan penelitian pustaka dan dianalisis menggunakan deskriptif-analisis. Hasil penelitian menunjukkan bahwa Husein Muhammad memperbolehkan poligami dengan syarat yang ketat yaitu mengenai keadilan. Penafsiran Husein Muhammad terhadap keadilan yang harus ditegakkan adalah keadilan secara material (al-qisṭ) dan mental-psikologis (al-‘adl). Jika dilihat dalam jangka panjang pemikiran ini adalah sebuah upaya yang dilakukan untuk menutup pintu poligami secara perlahan dengan memperketat syarat-syaratnya. Karena puncak atau ujung dari kehendak Allah Swt. adalah monogami dan hal tersebut harus diperjuangkan secara terus menerus.

Authors: Mohammed Masum Iqbal , Md. Emran Hossain
Published: August 2024

Bangladesh is one of the most densely populated countries in the world. The desired and right medical services for people are very important for any healthy nation. Many private hospitals as well as public hospitals are operating in Bangladesh to provide medical services for the people of Bangladesh. We know the survival and success of a private hospital depend on its patients’ satisfaction. The present study attempts to measure patients’ satisfaction with the medical services provided by a leading private hospital in Bangladesh. To measure the satisfaction of patients, SERVQUAL model has been applied in this study. The research involved SERVQUAL instrument to the service quality dimensions and asking 50 respondents as sample of patients to complete the questionnaire. Patient's responses on the basis of service quality dimensions have been obtained. The study depicts that most of the patients are merely satisfied or neutral with the medical services of the hospital in general and patients are more satisfied with tangibility than any other dimensions of service quality. The study has enabled to identify the areas where improvements are needed from the patients’ point of view. We know SERVQUAL model can be applied to measure the gaps between perception and expectation of the services provided, but this study is not including the gap measurement and the study is confined to a leading private hospital situated in Dhaka city only.

Published: August 2024

One of the reproductive health problems that women often experience is vaginal discharge. About 85-95% vaginal discharge is caused by the fungus Candida albicans. To maintain the cleanliness of the female organ system, feminine cleansing soap is usually used. The use of traditional ingredients has smaller side effects and the price is also relatively affordable. Traditional ingredients that can be used are young areca nut (Areca catechu L.) and Manjakani (Quercus infectoria). Young areca nut seeds contain tannins, flavonoids, and saponins, while Manjakani fruit contains tannins and flavonoids which have anti-fungal activity. This study aims to determine the inhibitory power of feminine cleansing soap from areca nut extract (Areca cathechu L.) and Manjakani extract (Quercus infectoria) on the growth of Candida albicans. This research is a purely experimental laboratory which begins with the extraction process. 5 formulations of feminine cleansing soap were prepared, a combination of young areca nut extract (Areca cathechu L.) and Manjakani extract (Quercus infectoria) with a concentration percentage ratio of 5:10, 7.5:7.5, 10:5, 15:0 respectively and 0:15. The resulting preparations were tested for inhibition of the growth of Candida albicans. The results showed that a feminine cleansing soap combination of young areca nut extract (Areca cathechu L.) and Manjakani extract (Quercus infectoria) had an inhibitory effect on the growth of Candida albicans, namely F1, F2, F3, F4 and F5 which had average inhibition respectively of 21.33 ± 0.58 mm, 21.67 ± 0.58 mm, 22 ± 0 mm, 19.67 ± 1.53 mm. Thus, the findings show that all feminine cleansing soap formulations of a combination of young areca nut extract (Areca cathechu L.) and Manjakani fruit extract (Quercus infectoria) have an inhibitory effect on the growth of Candida albicans. Of the five formulations tested, the combination of extracts with a ratio of 0:15 (F5) showed the highest inhibition against Candida albicans with a mean inhibition zone diameter of 22.33 ± 0.58 mm.

Authors: Saifudin Zuhri  , Sri Suwarni
Published: August 2024

The prevalence of low back pain (LBP) in Indonesia is increasing with age and deviant behavior in the workplace. If people are not aware of the vulnerability they feel, it can lead to deformities and disabilities as perceived severity. So that behavior changes with motivation for public health. This study aims to analyze the relationship between personal and work factors and the perception of LBP. This type of research is a cross sectional quantitative research. The research location is in Sukoharjo, Central Java. The sampling technique was purposive non-random sampling with a total sample of 120 respondents. Data were collected using questionnaires, then analyzed using multiple linear regression tests. The results of bivariate analysis showed that personal factors had a positive and significant correlation with the perception of LBP incidence (r=0.549, p<0.001). Occupational factors had a positive and significant correlation with the perception of LBP incidence (r = 0.680, p<0.000). Personal and occupational factors simultaneously affected the perception of LBP incidence with a p value of 0.000 and the contribution of these two variables to the perception of LBP incidence was 48.3%. It can be concluded that both partially and simultaneously, personal and occupational factors affect the perception of LBP incidence. Suggestions for further research are needed to explore other factors that influence the perception of LBP events. This is important to deepen understanding of the various aspects that can affect an individual's perception of LBP, including environmental, psychosocial, and lifestyle factors.

Published: August 2024

The occurrence of bullying behavior within SDN Bhakti Karya Jogja has the potential to create an environment that is detrimental to the physical and mental development of children. The observed bullying behavior within this context can be categorized as either physical or non-physical/verbal. The bullying observed in this study arises from misunderstandings and minor issues that have a significant impact on the mental wellbeing of those subjected to it. This study employs a qualitative approach in the form of a case study methodology. The research findings indicate that the forms of verbal bullying observed at SDN Bhakti Karya Jogja include slandering the victim and the victim's parents, mocking, threatening, and using profanity. With regard to the forms of physical bullying, these include hitting, taking things, and pinching. It can be observed that victims of bullying exhibit signs of distress. They become quiet, weak, afraid when they meet the perpetrators and tired of the perpetrators’ treatment. Additionally, they become markedly moody and disinterested in learning. Educational institutions have implemented a variety of strategies in response to bullying behavior. These include counseling, disciplinary measures, and the integration of early religious education into the curriculum. Furthermore, the incorporation of character education, comprising curricula designed to instill positive values and behaviors, has gained prominence as a strategy to promote constructive social interactions. Additionally, educational establishments have sought to utilize students' leisure time in productive endeavors, such as the provision of engaging learning activities.
Analysis of Health Disparities Among Different Socioeconomic Groups in Indonesia: Implications for Health Policy
Authors: Ginting Daniel , Suharto  , Fentiana Nina
Published: August 2024

The unequal distribution of economic resources can result in disparities in access to health services, particularly in lower-income communities where the lack of resources may limit the ability to obtain services that meet their specific needs. As is often the case in communities with lower economic status, individuals tend to prefer traditional medicine, facilitated by village shamans, over seeking care at nearby health facilities. In some literature, the factors contributing to the difficulty of accessing healthcare in communities with low economic status are attributed to two primary factors: internal factors and external factors. This lack of agency on the part of the community then gives rise to a middle ground in the form of a national health insurance program, commonly referred to as BPJS, which is accessible to people from a range of economic backgrounds. This study employs the descriptive qualitative research method, which involves a systematic and comprehensive examination of a given phenomenon or subject matter, with the objective of providing a detailed account of that phenomenon or subject matter in a way that is both accurate and insightful. The findings indicate that economic status continues to exert a significant influence on the manner in which health services are provided to the Indonesian population.

MENS REA
Authors: Dr. Neeraj Malik
Published: August 2024

Humans naturally discern purpose from unexpected outcomes. Small toddlers typically learn "I didn't mean to" as an excuse. Thus, pure supposition suggests that the ancient law held men accountable exclusively for their purposeful wrongdoings. All evidence suggests otherwise. "Law in its earliest days tries to make men answer for all the obvious ills their deeds cause"[1] It is sometimes believed that there is one state of mind common to all crimes, however other crimes need a different mental ingredient. The presumption is: “State-of-mind-X is common to all crimes and is sufficient for many, but some offences require some additional mental element, such as state-of-mind-Y or Z.”[2] Care must be taken to be sure that such a formula does not include too much. A person's mental condition may be too immature for mens rea. State-of-mind-X requires a person who is not too young. Again, for state-of-mind-X the mental faculties must not be too greatly disturbed by mental disease, and under certain circumstances they must not have been misled by reasonable mistake of fact, or have been constrained by compulsion.[3] Without going further into detail it is sufficient to point out the need of excluding every mental pattern which contains any factor sufficient in law to exculpate one who has done particular deed in question. If every such factor is excluded and there is present an intent to do the deed which constitutes the actus reus of a certain offense, the result may be said to be state-of-mind-X. It is necessary to add, however, that for certain crimes it will be possible to substitute some other mental factor for the actual intent to do the actus reus. In brief, while state-of-mind-X has certain factors which remain constant, these have to do with the general outlines of the mental pattern rather than with the minute details.

Authors: Facciani Matthew J. , Apriliawati Denisa , Weninger Tim
Published: August 2024

Although prebunking games have shown promise in Western and English-speaking contexts, there is a notable lack of research on such interventions in countries of the Global South. In response to this gap, we developed Gali Fakta, a new kind of media literacy game specifically tailored for an Indonesian audience. Our findings indicate that participants who engaged with Gali Fakta exhibited significantly greater skepticism toward false news headlines and expressed a reduced likelihood of sharing them. Importantly, playing Gali Fakta did not lead to increased skepticism or decreased sharing intent for factual headlines. These results suggest that Gali Fakta holds promise as a scalable media literacy intervention in Indonesia.

Educabilidad de las personas mayores. Análisis a partir de una experiencia de UNI 3 Montevideo
Authors: Quercini Díaz Diego Martín
Published: August 2024

La investigación consistió en conocer, describir y analizar las condiciones y habilidades que dan cuenta de la educabilidad de las personas mayores participantes de un taller en UNI 3 Montevideo. La perspectiva teórica adoptada entiende a la educabilidad como una construcción que se establece a través de componentes individuales de cada sujeto de aprendizaje en relación a un contexto social de aprendizaje, condicionando su experiencia educativa y la posibilidad de incorporar nuevos conocimientos, dinámicas de estudio, comunicación y aprendizaje, así como potenciar y construir lazos sociales y afectivos. Se ha podido verificar que el deseo de aprender de estas personas se manifiesta como una necesidad y como un medio para generar cambios personales. Esto indica que existe un deseo intrínseco de continuar desarrollándose en un sentido integral: que el aprendizaje no se direcciona a un saber hacer específico, sino a una dimensión más global, contemplando aspectos intrapersonales e interpersonales.

Authors: Achuo Kilian Ebua , Seraj Mehdi , Ozdeser Huseyin
Published: August 2024

This study investigates the determinants of coal consumption in China, contributing to the ongoing debate on whether to replace coal or remain the dominant energy source. The study examines data extracted from different reliable sources including British Petroleum (BP), world Bank Data Indicator (WDI) and International Monetary Fund (IMF) ranging from 1985 to 2020. Autoregressive Distributed Lag (ARDL) model set was employed to estimate the short-term and long-term dynamics of the variables. Unit root tests were performed to assess the stability of variables, and Granger causality test was employed to investigate directional links. The findings revealed that GDP, Government Expenditure and Industrialization have a positive significant marginal relationship with Coal consumption in both the short and long run, whereas Crude Oil Prices and Domestic Credit have a negative impact on Coal Consumption. The analysis also reveals unidirectional causality flow of all considered variables from economic growth rates. The results suggest that coal and oil should remain the dominant energy sources in the Chinese economy to increase energy efficiency while recommending gradual investment and research in energy they are also renewed, with attention to population growth.

The potential cognitive benefits associated with bilingualism have garnered substantial attention in recent years. The present meta-analysis aimed to synthesize and critically evaluate the existing evidence regarding the impact of bilingualism on executive function (EF), a set of cognitive processes vital for goal-directed behavior. A comprehensive literature search was conducted across multiple databases, encompassing studies published between 2018 and 2024. Studies were included if they employed a quantitative design, compared bilingual and monolingual individuals on at least one measure of EF, and reported sufficient statistical data for effect size calculation. A total of 32 studies met the inclusion criteria, yielding a combined sample size of 3,875 participants. The overall meta-analysis revealed a small but significant positive effect of bilingualism on EF (Hedges' g = 0.18, 95% CI [0.12, 0.24], p < 0.001). Moderator analyses indicated that the effect was moderated by the type of EF assessed, with stronger effects observed for inhibitory control and cognitive flexibility than for working memory. In conclusion, our study suggests that bilingualism is associated with enhanced EF. The magnitude of the effect varies across different EF components, highlighting the need for further research to elucidate the specific mechanisms underlying the bilingual advantage in cognitive control.

Aim: To evaluate changes in quality of life via the ageing male symptom scale (AMSS) and somatic, psychological, and sexual sub-scales following testosterone undecanoate (TU) or placebo (P) treatment in men with type 2 diabetes mellitus (T2DM) and adult-onset testosterone deficiency (TD) via a re-analysis of the BLAST (Burntwood, Lichfield, Atherstone, Sutton Coldfield, and Tamworth) randomised controlled trial (RCT).
Methods: Analysis of data from the BLAST RCT in men with T2DM and adult-onset TD was performed. Summation baseline and study-end AMSS data were available in 170 men (94: P; 76: TU) with subscale data available in 82 men. Rank-sum and sign-rank tests determined inter/intra-group differences, whilst linear/multiple regression models identified predictors of AMSS change.
Results: AMSS improved significantly in P [–2 (median), p = 0.010] and TU [–6 (median), p < 0.0001)] arms, with greater improvement observed in men on TU (p = 0.014). No significant change was seen in either arm with baseline AMSS < 27 (asymptomatic). TU was significantly associated with AMSS improvement in all symptomatic AMSS categories. Improvement in the P arm was confined to men with baseline AMSS > 49. In the cohort with subscale AMSS data, TU was associated with improvements in somatic, psychological, and sexual subscales, whilst improvement was limited to the somatic subscale in the men on P. TU (reference: P) and higher baseline AMSS were significantly and independently associated with AMSS improvement. The improvement in summation AMSS associated with TU (reference: P) was only evident in men with mild depression and no anxiety (based on baseline Hospital Anxiety and Depression Scale data).
Conclusions: TU appeared associated with improved AMSS (summation and subscales) in men with T2DM and adult-onset TD demonstrating symptoms (AMSS ≥ 27) with this benefit mediated by levels of depression and anxiety (European Union Clinical Trials Register, EudraCT 2008-000931-16).

BACKGROUND

Gut microbiota (GM) affects the progression and response to treatment in liver diseases. The GM composition is diverse and associated with different etiologies of liver diseases. Notably, alterations in GM alterations are observed in patients with portal hypertension (PH) secondary to cirrhosis, with hepatitis B virus (HBV) infection being a major cause of cirrhosis in China. Thus, understanding the role of GM alterations in patients with HBV infection-related PH is essential.

AIM

To evaluate GM alterations in patients with HBV-related PH after transjugular intrahepatic portosystemic shunt (TIPS) placement.

METHODS

This was a prospective, observational clinical study. There were 30 patients (with a 100% technical success rate) recruited in the present study. Patients with esophagogastric variceal bleeding due to HBV infection-associated PH who underwent TIPS were enrolled. Stool samples were obtained before and one month after TIPS treatment, and GM was analyzed using 16S ribosomal RNA amplicon sequencing.

RESULTS

One month after TIPS placement, 8 patients developed hepatic encephalopathy (HE) and were assigned to the HE group; the other 22 patients were assigned to the non-HE group. There was no substantial disparity in the abundance of GM at the phylum level between the two groups, regardless of TIPS treatment (all, P > 0.05). However, following TIPS placement, the following results were observed: (1) The abundance of Haemophilus and Eggerthella increased, whereas that of Anaerostipes , Dialister , Butyricicoccus , and Oscillospira declined in the HE group; (2) The richness of Eggerthella , Streptococcus , and Bilophila increased, whereas that of Roseburia and Ruminococcus decreased in the non-HE group; and (3) Members from the pathogenic genus Morganella appeared in the HE group but not in the non-HE group.

CONCLUSION

Intestinal microbiota-related synergism may predict the risk of HE following TIPS placement in patients with HBV-related PH. Prophylactic microbiome therapies may be useful for preventing and treating HE after TIPS placement.
