Authors: Ab Jalil Zaidatulnisha binti , Zakaria Nor Hidayati
Published: January 2024

Social media have functioned more than just a socializing site. Many parties have exploited the opportunities available within the social media application like education, business, networking engagement and much more. Like in business, social media seems to be a must platform for every business venture and has even been seen as the quickie way to start a business. The question is, do these so-called online business owners possess any specific entrepreneurial characteristics which influence their business performance? Or does it matter to possess specific entrepreneurial characteristics to excel in online business? Thus, this paper is to undergo a study to see if entrepreneurial orientation does have an impact on social media adoption and business performance among Bumiputera micro-entrepreneurs. This study is trying to integrate UTAUT theory and resource-based-view theory to evaluate how social media adoption may impact the business performance among the Bumiputera micro-entrepreneurs. A total of 239 micro-entrepreneurs were identified and responded to the survey. The result shows a positive relationship between social media adoption and business performance; however , the study shows no significance of entrepreneurial orientation to the relationship between social media adoption and business performance.

Purpose: The psychological well-being of students plays an important role that needs to be examined as it revolves around aspects of internal psychology in a less tangible manner. While a student’s external behavior may provide several insights into well-being, it does not reflect the internal psychological state of a student. This study will be carried out to give a detailed picture of the psychological well-being of primary school students. Methodology: An in-depth interview method was used to collect data. The individuals involved in this study consisted of 10 primary school Muslim Religious students in the residential area of Pahang, Malaysia. Findings: The analysis of these interviews revealed several key themes, including strength in oneself, social involvement, and family support system. The findings of this study can be used as required certificates to help practitioners understand the diverse perspectives on psychological well-being. These themes can be used to enhance family functionality to achieve and maintain psychological well-being and academic achievement in confronting life’s challenges. Implications for Research and Practice: Firstly, it is important to develop customized strategies that teachers, school counselors and professionals can use based on the findings of this study. These strategies should aim to improve the welfare of elementary school students from low-income backgrounds. Additionally, involving families in the process can be incredibly beneficial in creating a nurturing and supportive home environment for students. Lastly it is crucial to provide social skills training that incorporates activities promoting peer relationships, teamwork, and effective communication.

Published: January 2024

Sharia regional norms include Islam's dominant status, the principle of regional autonomy, and the Constitution of Indonesia, which served as its foundation. This is because several Sharia regional restrictions, such as the need to wear the headscarf and the ban on curfews for women, are discriminatory against women. This study aims to (1) determine whether or not regional governments have the ability to create Sharia regional laws and (2) identify the legal basis for Sharia regional regulations that do not allow for women's liberation. This study will be evaluated descriptively, using normative research with a statutory approach. Our findings indicate that Article 29 and Article 18 (paragraphs 1 and 2) of the Constitution provide the constitutional basis for the power to create Regional Regulations. Since the indications, constraints, and contents that Sharia regional rules may apply are not defined in the Indonesian legal system, the formulation of regional laws and their application remains controversial. Because of this, women may feel uneasy with the Sharia Regional Regulations. Furthermore, the Ministry has the authority to nullify contracts that violate regional Sharia norms that oppose and do not accommodate women's liberation. To better safeguard women's rights within the framework of Islamic law, the legal scholarship critical of Sharia regional restrictions and women's liberation is crucial. This study can significantly contribute to improving the legal framework and delivering gender equality and social justice by providing a critical analysis of rules and their implementation.

Authors: Alhattab Sevdenur , Jamil Khairil Husaini Bin
Published: January 2024

This study explores current viewpoints on how science and Islam can coexist in the Islamic context, delving into the dynamic conversation at the intersection. It discusses key figures and occasions influencing the interaction between religion and science in Islam, following the dynamic interplay from the modern to post-modern periods. One of the findings is that scholars who initially brought these discussions to the forefront in the modern age, such as Sir Syed Ahmed Khan, Jamal al-Din al-Afghani, and Muhammad Abduh, coincided with the rise of nation-states and the dissolution of the caliphate in 1924. The paper also delves into the ideas of Tantawi Jawhari’s “scientific miracle” and Naquib al-Attas’s “Islamization of science and knowledge.” It also sheds light on the ongoing discourse that aims to synthesise these domains and promote interdisciplinary convergence, particularly in the areas of religion and science.

Authors: Paranoan Anelsa , Chaesar Male Hendro Dwiky
Published: January 2024

Background: Estrogen may have a neuroprotective role in glaucoma, and estrogen insufficiency is thought to contribute to glaucomatous damage through both mechanical and vascular processes.
Methods: By comparing itself to the standards set by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. So, the experts were able to make sure that the study was as up-to-date as it was possible to be. For this search approach, publications that came out between 2014 and 2024 were taken into account. Several different online reference sources, like Pubmed and SCIENCE DIRECT, were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done.
Result: In the PubMed database, the results of our search brought up 93 articles, whereas the results of our search on SCIENCE DIRECT brought up 76 articles. The results of the search conducted for the last year of 2014 yielded a total 41 articles for PubMed and 26 articles for SCIENCE DIRECT. In the end, we compiled a total of  6 papers, 4 of which came from PubMed and 2 of which came from SCIENCE DIRECT. We included six research that met the criteria.
Conclusion: In summary, a longer duration of OC usage may be related with a higher risk of OAG; however, it is unclear if OC use in general raises the risk of OAG or whether this potential association is mediated by IOP. An earlier age at natural menopause may increase the incidence of OAG. Most significantly, PMH use may be related with a lower IOP, and the estrogen-only kind of PMH may be associated with a lower risk of OAG.

Published: January 2024

Background: Despite the critical role of chest physiotherapy in the recovery process post open-heart surgery, there is a paucity of data on the practices of physical therapists in Karachi. With the high incidence of cardiovascular surgeries and the significant burden of postoperative complications, understanding current physiotherapy practices is essential for improving patient outcomes.
Objective: The objective of this study was to evaluate the current practices of physical therapists regarding chest physiotherapy for patients undergoing open-heart surgery in Karachi and to identify potential areas for standardization and improvement.
Methods: A cross-sectional study was conducted using a questionnaire survey among 40 physiotherapists working in cardiothoracic units across six major hospitals in Karachi. Participants were selected through non-probability convenient sampling, and data on preoperative and postoperative physiotherapy practices were collected. The survey included both open-ended and close-ended questions, with an emphasis on the types of treatments administered during the first five postoperative days. Statistical analysis was performed using SPSS version 25.
Results: The mean age of the physiotherapists was 31.20 (SD = 6.8) years with an average working experience of 7.592 (SD = 6.7) years. On the day of surgery, physiotherapy was provided routinely by 7.5%, as needed by 62.5%, and was never provided by 30% of the respondents. From the first to the fifth postoperative day, routine physiotherapy was administered by an increasing majority, peaking at 100% on the second day. Written guidelines for the management of extubated and intubated patients were accessible to 35% and 10% of participants, respectively.
Conclusion: There is a substantial engagement in chest physiotherapy post open-heart surgery among physiotherapists in Karachi. However, the variability in practice and the lack of standardized guidelines point towards a need for the development and implementation of standardized protocols to ensure consistent and evidence-based care.

Published: January 2024

Background: Acanthosis Nigricans (AN) is a dermatological condition characterized by hyperpigmented, velvety plaques, commonly linked with insulin resistance, obesity, and hormonal disorders. The treatment of AN primarily focuses on managing skin changes, with topical agents like trichloroacetic acid (TCA) and tretinoin being explored for their efficacy.
Objective: The study aimed to compare the effectiveness of 15% trichloroacetic acid and topical 0.05% tretinoin in the treatment of Acanthosis Nigricans, focusing on improvements in hyperpigmentation and patient satisfaction.
Methods: This randomized control trial was conducted at Jinnah Postgraduate Medical Centre, Karachi, from August 2022 to June 2023. A total of 90 participants with diagnosed AN were recruited and randomly assigned into two groups: Group A (n=45) received 15% TCA peels every two weeks, and Group B (n=45) applied topical 0.05% tretinoin daily, both for a duration of 8 weeks. The efficacy was assessed using serial photographs and a grading system for improvement. Data analysis was performed using SPSS Version 25.0, with the Chi-square test employed for comparing efficacy.
Results: The mean age in Group A was 35.11 ± 7.05 years and in Group B was 37.20 ± 6.37 years. Group A showed a higher success rate with 42 participants (93.3%) demonstrating improvement, compared to 35 participants (77.8%) in Group B (P-value: 0.034, Odds Ratio: 4.000). Grades of improvement indicated that 26 participants (57.8%) in Group A and 14 (31.1%) in Group B experienced good improvement (51%-75%). Adverse effects such as erythema and post-inflammatory hyperpigmentation were more common in Group A.
Conclusion: The study suggests that 15% trichloroacetic acid may offer greater improvement in hyperpigmentation in Acanthosis Nigricans compared to topical 0.05% tretinoin. However, the treatment choice should consider individual patient factors, and further research is needed to confirm these findings.

Published: January 2024

The Bira-Pamatata crossing transportation service is carried out by three ships, namely KMP Bontoharu, KMP Kormomolin, and KMP Balibo. These three ships have different technical specifications, so the cost of production for the three ships is also other at the 60% load factor level as the basis for determining the tariff. However, the tariffs set for the three ships remain the same. Therefore, it is necessary to decide on the basis of the ship's operating pattern that meets the operational feasibility criteria based on the value of the applicable tariff. The results of the frequency base based on the load factor between the three ships are for KMP Balibo as many as 770 trips/year, KMP Kormomolin as many as 464 trips/year, and KMP Bontoharu as many as 439 trips/year. The method used to determine the basic operating pattern equation approach is the trendline method based on the relationship between frequency and load factor that meets the feasibility of operations. The validation results show that the basic operating pattern equation for the three ships is feasible based on the correlation test results and the mean average percentage error so that the equation can be used as the basis for setting the operating pattern of the Bira -Pamatata crossing.

Published: January 2024

High rate accumulation of sediment materials in front of the sea water intake (SWI) of a petrochemical factory cooling water system has caused high maintenance dredging costs. A study was conducted to identify the pattern and rate of sedimentation and to find an engineering solution that enables controlling sedimentation rate reduction. Based on numerical simulation, it is identified that the existing total rate of sedimentation around the channel in front of the SWI is 50cm/year. Further numerical simulation series revealed an optimum mitigation scenario by the construction of a pair of groin along both sides of the channel in front of the SWI as a sediment control structure. Under this scenario, the average bed level change becomes 0.10 cm/year and the maximum value of the bed level change is around 24.96 cm/year. A BPPT-lock armored rubble mound-type structure was designed for this sediment control groin by considering its feasibility, ease of construction, and local availability of structure materials. BPPT-lock is selected due to its high hydraulic stability (KD) of 17 for the trunk application and 13 for the head application. It is found that about twenty-five percent  more armor unit numbers were required at the final stage of construction compared to the designed one. The actual method of armor unit placement and arrangement during construction is considered the main cause of this difference. In this case, the calculation was designed for random placement, but the actual construction was in uniform placement. To provide economical insight, a calculation was made to compare the construction budget requirement between this constructed groin armored with BPPT-lock and if the same structure armored with tetrapod. The calculation result shows that BPPT-lock armor units required 64% less budget compared to the tetrapod.

Pelabuhan Bantaeng telah memiliki dermaga untuk proses bongkar muat barang dan penumpang. Masalahnya, pelabuhan tersebut belum bisa dioperasikan secara maksimal oleh karena besarnya tinggi gelombang di dermaga sehigga proses bongkar muat tidak maksimal. Dokumen Rencana Induk Pelabuhan Bantaeng merekomendasikan pembangunan breakwater. Salah satu tipe breakwater yang dapat diaplikasikan adalah hanging breakwater. Penelitian ini bertujuan untuk menganalisis dimensi hanging breakwater berdasarkan data lingkungan. Penelitian dimulai dengan mengumpulkan data gelombang laut dalam dan dokumen terkait. Gelombang laut dalam dianalisis untuk mendapatkan parameter gelombang di lokasi bangunan. Struktur ini akan diletakkan pada kedalaman 20 m. setelah parameter gelombang di lokasi struktur diketahui, selanjutnya menghitung koefisien transmisi dengan menggunakan persemaan yang dikembangkan oleh peneliti terdahulu [2]. Koefisien transmis selanjutnya digunakan untuk menghitung gelombang di belakang bangunan. Gelombang di belakang bangunan harus lebih kecil atau sama dengan tinggi gelombang dipersyaratkan [3]. Hasil yang diperoleh menunjukkan bahwa semakin tinggi gelombang di depan bangunan adalah Hi = 1.79 m, tinggi gelombang di belakang model adalah yang dipersyaratkan adalah Ht = 0.7 m dan koefisien transmisi adalah Kt = o.8. Lebar bangunan pada arah perambatan gelombang dapat dihitung dangan menggunakan persamaan L=46.757e(-0.08D).

Kerang air tawar bukan hanya sekadar organisme perairan biasa, keberadaannya memiliki dampak yang signifikan dalam konteks perikanan dan ekosistem air tawar. Sebagai biofilter alami, kerang air tawar memainkan peran krusial dalam menjaga kualitas air dengan menyerap dan membersihkan zat-zat berbahaya, sekaligus menyediakan lingkungan yang optimal untuk pertumbuhan ikan dan organisme perairan lainnya. Meskipun kerang memiliki potensi besar sebagai sumber daya alam yang beragam, saat ini pemanfaatannya masih terbatas pada penggunaan daging kerang sebagai bahan pangan dan kulit kerang sebagai hiasan. Cangkang kerang mengandung zat kapur (Kalsium karbonat CaO) sehingga baik digunakan dalam pencampuran beton. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana penambahan cangkang kerang berdampak pada tingkat perubahan mutu dan kekuatan tarik beton. Metode yang digunakan adalah pengujian kuat tarik beton di laboratorium (eksperimental). Sampel yang diuji adalah sampel dengan tiga variasi campuran cangkang kerang yaitu 0% cangkang (4 sampel), 10% cangkang (4 sampel) dan 25% cangkang (4 sampel). Tahapan pelaksanaan meliputi; pembuatan sampel uji berupa silinder beton, perawatan sampel uji dan pengujian kuat tarik. Hasil penelitian menunjukkan meningkatnya kuat tarik beton pada penambahan 10% cangkang kerang dengan nilai kuat tarik 2,03 Mpa dan mengalami penurunan kuat tarik beton pada penambahan 25% cangkang kerang dengan nilai kuat tarik 1,24 Mpa. Proporsi penambahan cangkang kerang yang ideal untuk pencampuran beton pada penelitian ini adalah 10% karena dapat meningkatkan kuat tarik beton.

Most plastic waste is not processed properly and can cause pollution to the surrounding environment. This problem is currently being faced by residents of Gunung Putri Bogor District, low knowledge and lack of contribution from residents in managing organic waste and non-organic waste, leads to the dumping and burning of waste in quite large quantities, which can trigger air pollution and disease, so the aim in This service is to evaluate the effectiveness of various waste management methods, especially in the context of waste sorting, to raise awareness of the importance of managing plastic waste on a small scale, as well as providing a positive impact on environmental conservation efforts. It is hoped that the knowledge generated from this research can be used as an initial reference to increase public awareness in waste management and also encourage active community participation in reducing the impact of environmental pollution produced through a triggering approach, namely encouraging behavior change by providing information and training in the form of waste management workshops. plastic so that residents have the opportunity to handle and manage dry waste (organic and inorganic). The method used in this activity was that the researcher gave a pre-test and post-test before and after the activity. The researcher wanted to measure the level of knowledge and understanding, attitudes, and behavior of the participants in waste management. The results achieved by researchers show a growth in knowledge, attitudes, and behavior of participants in the use of small plastic waste as well as the role of the community.

All age groups are fond of bakery items, although middle-class and lower-class people in Bangladesh are especially prominent. However, this food product's ingredients, manufacturing process, and packaging all have the potential for heavy metal contamination. As a result, the mean concentrations of Cr, Mn, Cu, Ni, Cd and Pb in 18 different brands of local bakery items, while others were from well-known brands readily available in Rajshahi City, were evaluated using an atomic absorption spectrometer. The concentrations of Cr, Mn, Cu, Ni, Cd, and Pb were 0.34–1.66, 0.29–1.70, 0.19–1.27, ND–7.04, ND–0.38, and ND–1.33 mg/kg, respectively. The order of the metal content was Ni> Mn> Cr> Pb> Cu> Cd, with their polluted values. According to the results, some cereals and cereal-based food product samples included levels of Ni, Pb, & Cd that were greater than the permissible range recommended by the World Health Organization. Fewer samples typically exceed the acceptable limit than all of them. The metals' estimated daily intake levels did not exceed the permitted intake thresholds. On the other hand, the amounts of healthy nutritive metals like Mn and Cu that were ingested from that foodstuff were relatively small and barely met the daily demands for these nutrients. As a whole, the heavy metals' estimated target hazard quotients were < 1, indicating that people who regularly use these goods on a daily basis shouldn't have any health concerns.

Chromium plating process is the most effective way of protecting the base material against hostile environment or improving surface properties of base material. There are several problems with traditional chrome plating. Traditional process uses toxic acid baths and may cause various health conditions. The baths employed contain chromic acid in which the chromium is in the hexavalent state. Hexavalent chromium has been proved to have toxic, mutagenic and cancerogenic effects for human health. As a result, In Europe, the implementation of the reach initiative will increase fees on companies still using Cr (VI) in 2017 and will require action plans to phase out Cr (VI) in the future. This has left the plating industry in a very delicate position with dark future prospects unless new solutions that are both effective and environmentally friendly are discovered. Superchrome Physical Vapor Deposition coating ahead of looming industry regulatory actions that will drive towards the removal of hazardous hexavalent chromium compounds. These new sputtered chromium coatings do not require a protective paint top coat to pass exterior automotive trim specifications. Visually the chromium coatings match those of electroplated decorative chromium in color and appearance.

Phenomenology of Dementia
Authors: Barry Elizabeth
Published: January 2024

This article will explore the subjective experience of time for people living with dementia, exploring the implications of the loss of the ability to expect, as well as to remember, and how this conditions lived experience. It will also look to intersubjective time as a condition of relationality and a structuring condition for reciprocal and empathic care. It uses an approach informed by neurobiology and phenomenology to analyze these forms of temporal experience, looking notably at features such as expectation and surprise, and their non-normative presentation in those living with dementia, following the methods of psychiatrist Eugene Minkowski, neurobiologist Francisco Varela, and philosopher Natalie Depraz. Finally, it will look to memoirs by those with dementia, as well those who live close to them, to add texture and emotional resonance to the scientific and philosophical accounts of time in dementia.
