Authors: Adnan Mahany
Published: June 2024

Postoperative cataract surgery often results in posterior capsule opacification (PCO), causing low visual acuity and uniocular diplopia. Factors include patient age, lens type, surgery technique, and diseases. YAG capsulotomies, a noninvasive procedure, can cause complications like pressure elevation, IOL damage, inflammation, and retinal detachment. The study aims to evaluate the effect of Nd: YAG laser posterior capsulotomy on a patient`s refractive status. This study was conducted at Benghazi Teaching Eye Hospital in Libya. The sample consisted of patients who had anterior capsulorrhexis during cataract surgery and had anterior capsulotomies. Patients were selected based on their condition and underwent a comprehensive eye examination, including refraction, unaided visual acuity, and best-corrected visual acuity. Postoperatively, posterior capsulotomies were performed using a Nd: YAG laser. The surgical techniques involved administering a single shot of Nd: YAG laser, administering topical anesthetic agents, clearing the central posterior capsule, and applying energy levels. The mean age of 63.45 + 7.69 years, with a majority being female (63.6%) and (60.6%) right side eye. The procedure significantly impacted the participants' visual acuity(P<0.001), with changes in sphere, cylinder, and spherical equivalent measurements (<0.001). A one-month follow-up showed significant improvement in visual acuity, with a trend towards better refractive outcomes. The stability of the cylinder axis suggests a consistent correction of astigmatism post-operatively. The results demonstrate positive long-term outcomes in this study. With the average centroid being 0.52D at 26°±1.31D and 0.65D at 27°±1.23D at one month.

Intelligent Control System based on Wavelet Type-2 Fuzzy Neural network Design For Robot System
Authors: Duc-Hung Pham
Published: June 2024

In this paper, we propose a wavelet type-2 fuzzy brain imitated controller (WT2FBIC) for nonlinear robotic systems. The suggested method combines a wavelet type-2 fuzzy system (WT2FS) and a brain imitated controller (BIC) to improve learning efficiency. The system's inputs, which comprise a sensory and an emotional channel, eventually lead to the network's output. The WT2FBIC parameter update rules use the Lyapunov theory and the gradient descent method. To correct for the WT2FBIC in a main controller, a robust controller can be used for compensation. Robots find applications in a wide variety of industries thus the proposed WT2FBIC-based control system is used to control nonlinear robotic systems. In this work, a two-jointed robotic manipulator control system used the proposed method is demonstrated. The comparison of the proposed method with recent methods point out the effectiveness of the proposed method. The simulation results indicate that the proposed control approach provides good control performance.

Published: June 2024

Antibiotic contamination of natural resources and the receiving environment is of great concern. This brief discussion consists of the sources regarding antibiotic contamination and the analysis of several viable methods of removing antibiotic substances. The sources include domestic discharges, agricultural runoff, and pharmaceutical manufacturing effluents. Antibiotics are classified as emerging contaminants attributed to their persistence in the environment. Antibiotics and their metabolites enter the environment through human and animal urine and faeces. Persistent pollutants are introduced to aquatic ecosystems as they pass the wastewater treatment process. The overuse of antibiotics has led to the emergence of bacteria and genes resistant to antibiotics in the environment. This study provides a descriptive overview of antibiotic sources in the environment, their harmful effects, analytical techniques for its detection in wastewater, related challenges in monitoring antibiotic contamination in water, and recently used techniques for its removal from wastewater and problems associated with current strategies. The study also underscores the importance of understanding the sources and learning how to successfully apply methods to minimise the effects of antibiotic contamination in wastewater.

Authors: Firmansyah Ugiadam Farhan , Suryoadji Kemal Akbar , Bashirudin Jenny , Bramantyo Brastho , Alviandi Widayat
Published: June 2024

Background: Otitis media with effusion (OME) is the presence of middle ear fluid without acute ear infection signs or symptoms. OME is one of the causes of hearing loss. Chronic asymptomatic OME could be managed by careful waiting for 3 months because it is a self-limiting disease. During surveillance, autoinflation is a beneficial intervention with minimal side effects and high adherence. Objective: To evaluate the effectiveness of autoinflation to improve hearing in otitis media with effusion and hearing loss. Methods: Literature searching was conducted through PubMed, Cochrane, ScienceDirect, Scopus, and EBSCOHost with inclusion and exclusion criteria. The articles were selected and underwent critical appraisal using rapid critical appraisal of systematic review and level of evidence by the Oxford Centre for Evidence-based Medicine in 2011. Result: One systematic review and meta-analysis, or RCT, met the criteria. This article revealed a pooled estimate of RR 1.74; 95% CI [1.22-2.50] with a Z-score of 3.02 (p=0.0025). This result showed substantial significant (p=0.01) heterogeneity (I2=69%). Conclusion: OME patients with hearing loss who performed autoinflation >1 month had a 1.74 times greater chance of achieving hearing improvement than controls. Autoinflation with the Politzer method gives significant results in improving hearing loss. Large-scale RCT research is recommended to evaluate the effectiveness of autoinflation with the Politzer method or other available methods in OME patients with hearing loss.

Published: June 2024

Due to their aesthetic demand and high training load, ballet dancers are often at risk of low energy availability (LEA), with or without eating disorders (ED). A prolonged state of LEA may alter physiological function and lead to other major health concerns. This study aims to analyze the risk of LEA and eating disorders in female elite dancers at X dance school in Jakarta. This descriptive cross-sectional design study was followed by 11 dancers. Risk of LEA was assessed using the low energy availability in females questionnaire (LEAF-Q), eating behaviors using the eating attitude test (EAT-26) questionnaire, and body composition using the bioelectrical impedance analysis (BIA) instrument. A total of 18.2% of dancers were at risk of LEA (LEAF-Q score ≥8) and no dancers were at risk of eating disorders. The most common characteristics of LEA are gastrointestinal dysfunction (90.9%), followed by menstrual disturbance (45.5%), and musculoskeletal injury (9.1%). Compared to the first study in Indonesia, this study showed lower proportion of dancers at risk of LEA and ED at X dance school in Jakarta. Despite a lower proportion, most dancers experienced other characteristics of LEA, thus prevention and health management are required to reduce further health issues.

Published: June 2024

Analysis of aVR leads on electrocardiography (ECG) is often given less attention, when in fact ST-segment elevation in aVR leads and diffuse ST-segment depression in other leads indicates circumferential subendocardial ischemia, which can be caused by left main coronary artery occlusion (LMCA) or three-vessel coronary artery disease (3VD) and is associated with a poor prognosis. An 83-year-old male came to the emergency room with chest pain for 18 hours. The ECG showed ST-segment elevation in the aVR with diffuse ST-segment depression in the anteroinferolateral leads. He was diagnosed with acute coronary syndrome (ACS), suspected occlusion of the left main coronary artery (LMCA), and a differential diagnosis of three-vessel coronary artery disease (3VD).

During in-hospital treatment, ECG evaluation showed improvement of aVR ST-segment elevation. Early recognition of ACS with aVR ST-segment elevation and prompt early management are important.
Corporate Sustainability Reporting Directive (CSRD) and His Future Application Scenario for Italian SMEs
Authors: Celli Massimiliano , Arduini Simona , Beck Tommaso
Published: June 2024

The aim of this paper is to outline the salient points of CSRD (2022/2464/EU Directive) and reflect on its application for smaller enterprises, which typically have fewer resources than their listed counterparts. For these small entities the challenge of sustainability turns out to be more impactful and complex, potentially constituting an “information tsunami” for which they may find themselves completely unprepared. The theoretical framework underpinning this paper is overload theory. This theory, also linked to the economic and accounting background, is deeply rooted in the international academic literature as a “hot topic”, which suggests that processes may lead to increased cognitive overload due to excessive information volume. To test our hypothesis about the potentially overwhelming burden of environmental, social and governance (ESG) reporting for small-medium enterprises (SMEs), we decided to observe how Italian ones use and manage the Sustainability Reporting (SR) as a voluntary tool. For this purpose, we carried out an empirical study related to a descriptive statistic based on a sample of 72 innovative Italian SMEs. To apply the utmost scientific rigor to our judgments, in accordance with the extensive literature reviewed, including in the field of accounting, we have based our empirical study on the established methodological technique of Content Analysis.

Forest management decisions that consider both short- and long-term objectives are becoming more challenging and costly, due to market uncertainty, labor shortages, and the evolving forest industry. Under such unpredictable circumstances, a better understanding of the production economics of various silvicultural prescriptions is crucial in implementing sound forest management activities. The objectives of this study were to: a) estimate stump to landing productivity and cost for Early Commercial Thinning (ECT) and Group Selection (GS) prescriptions; and b) compare the harvest system cost ($/PMH) using machine rate and PATH (Planning and Analysis in Timber Harvesting) methods. Detailed time-motion studies were conducted in the spruce-fir forest of Northern Maine, USA, during the summer of 2019. The results, as expected, indicated the harvesting costs were 23% higher for ECT (21.08 $/m3) compared to GS (16.32 $/m3). The average productivity of the harvester and forwarder were reduced by 15 and 37%, respectively, for ECT compared to GS. The estimated harvesting system cost ($/PMH) was 4% higher as indicated by PATH compared to machine rate method. Higher operational productivity in GS can be attributed to the larger volume of logs, and shorter travel loaded distance than ECT. These findings can help forest managers make more informed decisions while implementing appropriate silvicultural prescriptions under varying conditions based on management objectives and market conditions.

Data pribadi merupakan salah satu aspek penting dalam kehidupan seorang manusia baik sebagai individu (hak privasi) maupun dalam kedudukannya sebagai warga negara (hak warga negara) perlu mendapat perlindungan hukum yakni melalui penerapan sistem hukum pidana. Pentingnya penerapan sistem hukum pidana dalam hal ini, mengingat terdapat berbagai macam kasus yang berkenaan dengan penyalahgunaan data pribadi seorang warga negara dalam berbagai aspek kehidupan sosial, berbangsa dan bernegara baik dilakukan secara individu, perusahaan (korporasi) maupun oleh pihak-pihak yang diberikan kewenangan untuk mengumpulkan, memporoses hingga sampai penyebarluasan data pribadi secara melawan hukum, baik dalam kedudukannya sebagai subjek data pribadi, pengendali data pribadi dan prosesor data pribadi. Tujuan peneltian ini adalah untuk mengetahui penerapan sistem hukum pidana, terhadap penyalahgunaan data pribadi, khususnya menyangkut sistem pemidanaan yang diatur dalam UU Perlindungan Data Pribadi. Hasil penelitian menunjukan bahwa, walaupun telah ada pengaturan hukum khusus yang mengatur tentang Perlindungan Data Pribadi, yakni Undang-Undang RI Nomor: 27 Tahun 2022 Tentang Perlindungan Data Pribadi. Namun dalam konstek penerapan hukum pidana belum dapat diterapkan sesuai dengan pengaturan Pasal 65 sampai dengan Pasal 73 yang mengatur tentang larangan penyalahgugunaan data pribadi dan pengaturan tentang ketentuan pidana yang dilakukan baik oleh orang pribadi, badan hukum (korporasi) di Indonesia. Faktor-faktor penyebabnya adalah pertama, formulasi kebijakan hukum oleh pembentuk undang-undang lebih mengedepankan sanksi administratif; kedua, penyelesaian masalah/sengketa dapat dilakukan diluar sistem peradilan (alternative dispute resolution). Ketiga, penegakan hukum pidana dan/atau pemidanaan merupakan upaya hukum terakhir (the lass resource), dan keempat, merupakan salah satu faktor yang paling mempengaruhi adalah belum terbentuknya Lembaga Perlindungan Data Pribadi sebagaimana dimaksud dalam ketentuan Pasal 58 UU Perlindungan Data Pribadi.

Penelitian ini membahas isu tentang penggunaan klausula eksonerasi dalam Perjanjian Pengikatan Jual Beli (PPJB) Rumah Susun dalam kaitannya dengan prinsip-prinsip perlindungan konsumen. Penelitian yang digunakan adalah penelitian yuridis normatif. Hasil penelitian dapat disimpulkan bahwa penggunaan klausula baku dalam PPJB dimungkinkan sejauh tidak bertentangan dengan Pasal 18 ayat (1) UU Perlindungan Konsumen dan tidak mencederai kehendak para pihak, sebab yang halal dan itikad baik. Konsumen yang merasa dirugikan memiliki hak untuk mengajukan pembatalan klausula baku yang telah dilarang oleh UU Perlindungan Konsumen. Dalam proses penyusunan perjanjian, konsumen juga perlu melakukan upaya-ypaya preventif dengan membaca isi perjanjian dan memproyeksikan resiko atau implikasi dari sahnya suatu perjanjian
PERLINDUNGAN HUKUM BAGI MASYARAKAT TERHADAP PENCEMARAN UDARA AKIBAT INDUSTRI PELEBURAN LIMBAH DAUR ULANG ALUMINIUM
Authors: Pratistita Made Wipra , Triadi Irwan
Published: June 2024

Aluminum merupakan logam yang dipergunakan sebagai bahan dasar pembuatan produk peralatan kebutuhan manusia. Produk berbahan aluminium yang tidak dipergunakan sering kali menjadi sampah atau limbah yang dapat didaur ulang. Pendaurulangan limbah aluminium dilakukan dengan cara peleburan. Proses peleburan aluminium tentunya menghasilkan buangan gas yang apabila dilepas ke alam bebas berdampak pada menurunya kualitas udara bersih. Penelitian ini membahas sejauh mana perlindungan hukum yang dapat dilakukan terhadap perilaku industri peleburan aluminium yang membuang limbah gas hasil peleburanya ke alam bebas jika dilihat dari peraturan perundang-undangan. Dalam penelitian ini penulis mempergunakan metode penelitian hukum normatif dengan menggunakan sumber hukum dari bahan hukum primer berupa peraturan perundang-undangan hukum lingkungan dan bahan hukum sekunder berupa buku-buku dan artikel mengenai pengelolaan limbah berbahaya dan beracun. Kesimpulan yang didapatkan dalam tulisan ini yaitu pembuangan gas hasil peleburan limbah aluminium yang melewati standar baku mutu udara dapat dilakukan proses penegakan hukum berdasarkan ketentuan perundang-undangan yang berlaku.
On the lcm-sum function over arbitrary sets of integers

Let \(\mathbb{N}\) denote the set of all positive integers. For \(j,n\in \mathbb{N}\), let \((j,n)\) and \([j,n]\) respectively denote their gcd and lcm. If \(S\subseteq \mathbb{N}\) and \(\alpha\) is a real number then define \(L_{S,\alpha}(n)\) to be the sum of \([j,n]^\alpha\), where \(j\in \{1,2,3,\ldots,n\}\) for which \((j,n)\in S\). In this paper we obtain asymptotic formulae for the summatory functions of \(L_{S,a}(n)\) and \(L_{S,-a}(n)\), where \(a\in \mathbb{N}\) and \(a\geq2\). Apart from deducing some results proved earlier for $S=\mathbb{N}$ by Ikeda and Matsuoka, certain new asymptotic formulae are obtained here.

Diophantine approximation by prime numbers of a special form
Authors: Todorova Tatiana
Published: June 2024

We show that whenever \(\delta>0\), \(\eta\) are reals and constants \(\lambda _i\) subject to certain assumptions, there are infinitely many prime triples \(p_1, p_2, p_3\) satisfying the inequality \(|\lambda _1p_1 + \lambda _2p_2 + \lambda _3p_3+\eta| < (\max p_j)^{-1/18+\delta }\) and such that, for each \(i\in\{1,2,3\}\), \(p_i+2\) has at most 7 prime factors. The proof uses Davenport–Heilbronn adaption of the circle method together with a vector sieve method.
