The optimization of gas pipeline networks is critical for efficient and cost-effective transportation of natural gas. This study develops a mathematical model capable of analyzing different network configurations, including branched and branched-cyclic topologies, to explore the optimization of gas pipeline network conditions. The research provides valuable insights into the gas pipeline network optimization process, empowering industry stakeholders to make informed decisions and enhance performance in terms of efficiency, reliability, and cost-effectiveness. To attain these objectives, this study utilizes advanced simulation tools, state-of-the-art optimization algorithms, and sophisticated mathematical models that accurately represent the network's behavior. The optimization process aims to minimize the network's power requirements while simultaneously maximizing gas flow rate and optimizing line pack, ensuring optimal utilization of the pipeline infrastructure. The VIKOR (VIekriterijumsko KOmpromisno Rangiranje) method is identifying the most optimal network configuration and operating conditions. Our analysis applies this approach to three case studies, demonstrating its effectiveness in identifying the best network configurations. Additionally, the calculations of total cost and fuel consumption coincide with relative closeness, which confirms the accuracy of our proposed method, whereas optimal scenarios of the three cases have the minimum total cost among all scenarios. In conclusion, this research successfully develops a mathematical model and optimization approach to tackle the complexities of gas pipeline network optimization. The application of The VIKOR method and the analysis of case studies offer substantial evidence of its effectiveness.

In today's global economy, effective supply chain management plays a pivotal role in the success of a business. The repercussions of a business strategy on the entire supply chain remain uncertain until it is implemented. Utilizing simulations offers the opportunity to gauge performance before implementing the strategy. The primary aim of employing supply chain simulation is to analyze the effects of different strategies on profit enhancement and cost reduction across all supply chain tiers. This research paper has formulated a discrete event simulation model using Arena software to evaluate and enhance the operational efficiency of the detergent supply chain. The problem involves multiple levels and commodities, encompassing four manufacturers, two intermediate storage warehouses, and four main distributors following an (s, S) inventory control approach. Shortages are permitted, leading to a partial loss or back-ordering of products. The overarching objective is to minimize the overall inventory costs within the system, accounting for holding costs at each tier, managing shortages, and the expense incurred due to lost sales. A range of scenarios are developed to set control parameters, with the evaluation of supply chain performance falling into two main categories: financial and operational considerations.
SLC16A3 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: August 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that solute carrier family 16 member 3, encoded by SLC16A3, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. SLC16A3 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of SLC16A3 in primary tumors was correlated with patient distant metastasis-free and recurrence-free survival. Modulation of SLC16A3 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Authors: Ritchie Stephen Douglas , D'Angelo Jonah , De Feo Gian , Takano Takako , Priest Simon
Published: August 2023

Outdoor learning often reflects a wide variety of approaches that include but are not limited to, skill acquisition, outdoor education, adventure education, environmental education, experiential education, integrated learning, recreation, personal growth, and therapy. Thus, the case for transdisciplinarity in outdoor learning reflects a diverse integration and amalgamation of knowledge, methodologies, and disciplines - including health and ecohealth. Germaine to our paper, ecohealth is a transdisciplinary term that draws on system theory and the principle of reciprocity to reflect the holistic health of people, animals, plants, and the entire ecosystem where they live. The purpose of our paper is threefold: (1) systematically define key terminology and concepts from the literature related to holistic health, well-being, and wellness; (2) present the case for ecohealth promotion as a relevant and synergistic approach that is compatible with outdoor learning; and (3) share some practical implications for ecohealth promotion in outdoor learning contexts.

Authors: Lamichhane Puja , Pathak Bandana , Khadka Jwolan
Published: August 2023

Introduction: Pain is one of the major and common symptoms a patient goes through during root canal treatment (RCT). Calcium hydroxide [Ca(OH)2] combined with normal saline (NS) is commonly used as an intracanal medicament against root canal pathogens, but combination of Ca (OH)2 with chlorhexidine (2% CHX) is not routinely used. Aim of this study is to compare the combination of Ca(OH)2 +NS and Ca(OH)2 +2% CHX to reduce the interappointment pain in RCT.
Methods:  A comparative, prospective, qualitative study was conducted in the Department of Conservative Dentistry and Endodontics, KIST Medical College and Teaching Hospital from September 2022 to March 2023. Total of 60 patients aged 16-70 years were included in the study. Group I received Ca(OH)2+NS and group II received Ca(OH)2 +2% CHX. Pain score was recorded using visual analogue scale (VAS) from baseline to 6,12,24 and 48 hours.
Results: The mean pain score after 6 hours for Group I was 0.93(±0.83) and Group II was 1.43 (±0.63); P=0.011. The mean pain score after 12 hours for Group I was 0.40(±0.56) and Group II was 0.90(±0.66); P=0.003. 24 hours, mean pain score for Group I was 0.27(±0.45) and Group II was 0.60(±0.56); P=0.014. Patients reported reduction of pain after 24 hours, with Ca(OH)2 +NS (Group I) than Ca(OH)2 +2% CHX (Group II).
Conclusion: The combination of Ca(OH)2 +NS was more effective in reducing interappointment pain than Ca(OH)2 +2%CHX.

Hereby we are presenting a rare case of Pelviureteric junction obstruction in a malrotated ectopic kidney with concomitant lithiasis in a 16 year male. He presented with pain in lower abdomen intermittently. On CT scan, a left malrotated ectopic kidney was located in the pelvis near the midline with a 10 mm stone in the lower pole, and having obstructed pattern drainage with moderate hydronephrosis. Open Anderson-Hynes dismembered pyeloplasty was done.
Thorough clinical approach with delineating aberrant anatomy of ectopic kidneys and their vascular supply with consideration of unusual functional data on conventional functional renogram is necessary for intervening in malrotated ectopic kidney with concomitant lithiasis.
Sources of the Encyclical „Ut unum sint"
Authors: Přibyl Stanislav
Published: August 2023

John Paul II’s encyclical Ut unum sint on commitment to ecumenism was published 30 years after the ground-breaking ecumenism decree of Vatican II Unitatis redintegratio. It was meant to present a summary of everything the Catholic Church and its partners achieved in the field of ecumenical efforts. However, the article does not list these achievements but discusses the very fundamentals of Catholic identity, namely, how the Catholic Church is to remain faithful to itself in developing ecumenical dialogue with other churches and ecclesial communities. The article thus provides a detailed analysis of the way the encyclical uses the basic sources of faith, that is, the logia of the Sacred Scripture, Church Fathers and the Magisterium. As one might expect, the documents of the Magisterium that are quoted are the documents of Vatican II because this council represents a real turning point in the relations of the Catholic Church towards ecumenism. The article also considers the role of the canon law for ecumenism because both codices of canon law as well as the ecumenical directory represent major tools for the realisation of ecumenical efforts.
Love Builds Communion between Persons (UUS, n. 21): Christological-Ecclesiological Key to Confirm the Identity of Marriages of Baptised Non-Catholics
Authors: Pastwa Andrzej
Published: August 2023

The words derived from the Ut unum sint encyclical as well as the fruits of the newest research by theologians (among others the members of the International Theological Commission) on the meaning of the Catechism formula of Christian Marriage: “the Sacrament of Faith in the Service of Communion” — became an inspiration to attempt to verify the assumptions confirming the sacramental Identity of Marriages of Baptised Non-Catholics. The author assumes that the today’s challenge for the study of canon law should be to explore more the subject matter of the “the mystery of communion” (UUS, n. 5) in all the complexity of its detailed issues, including the development of relevant conclusions in the canonical (lawmaking) and canonical-pastoral (application of the law) spheres. This is in the name of the rule that church legislation, especially in clarifying key/systemic issues — and among such is the issue of the universality of Bellarmine’s principle of eo ipso sacramentum — is always based on the widely adopted theological foundations.
Sharing the Eucharist? Critical Comments from a Canonical Perspective on the Statement “Together at the Lord’s Table” (2019) of the Ecumenical Study Group of Protestant and Catholic Theologians
Authors: Dvořáček Jiří
Published: August 2023

The following article analyses the statement of the Ecumenical Study Group of Protestant and Catholic Theologians entitled “Together at the Lord’s Table” (2019) from the perspective of canon law of the Latin Church. First, it briefly presents the content of the statement, then it summarises the opinion of the Congregation for the Doctrine of the Faith. The article shows that the alternate participation in the Protestant and Catholic service of celebrating the Lord’s Supper / Eucharist by virtue of baptism alone is problematic from the perspective of Catholic canon law. Canon law builds on Catholic ecclesiology and sacramentology, based on the connection between baptism and the Church as well as the Church, the ministerial priesthood, and the celebration of the Eucharist. The article, then, shows the instruments of canon law for the protection of the Catholic faith regarding the apostolic succession as the only valid condition for presiding over the Eucharistic community and the Eucharist as the substantial presence of Christ. In the final chapter, the implications of participation in ecumenical worship for the Catholic faithful will be summarised. The participation of Protestants in Catholic worship, as proposed by the Statement, is not explicitly regulated by canon law. The CIC, in Canon 844 § 4, lays down only the conditions under which Protestants may licitly receive selected sacraments (the Eucharist, the anointing of the sick and the sacrament of penance), while for a valid reception of the Eucharist their baptism alone enables them.

Authors: Linggasari Shenny
Published: August 2023

Stockpile batubara merupakan tempat penimbunan sementara di lokasi Pengolahan Batubara sebelum batubara diangkut ke Dermaga / pengguna akhir. Indonesia memiliki curah hujan yang tinggi (> 3000 mm/tahun), sehingga sangat memungkinkan timbul limbah cair saat musim hujan sebagai akibat dari adanya air larian (run off) yang menggerus tanah atau mencuci batubara. Air larian ini membawa padatan tersuspensi dan berpotensi mempengaruhi kualitas air dan kualitas lingkungan. Tujuan penelitian untuk mengkaji pelaksanaan pengelolaan limbah cair stockpile batubara yang dilakukan oleh PT. X yang berlokasi di Sumatera. Hasil penelitian menunjukkan tahapan proses pengelolaan limbah cair stockpile batubara yang memiliki kandungan TSS yang tinggi tersebut berlangsung melalui proses koagulasi dan netralisasi. Penggunaan koagulan dalam bentuk bongkahan besar menyebabkan proses pencampuran koagulan dengan partikel tersuspensi tidak berlangsung sempurna. Jika langkah pertama tidak berlangsungsempurna maka langkah selanjutnya akan menjadi kurang efektif, dan kurang efisien.. Agar proses pengolahan limbah berlangsung efektif dan efisien, maka tahapan pengolahan limbah disarankan melalui proses koagulasi, flokulasi, pengadukan, sedimentasi dan netralisasi.

Purpose: In this study, we investigated epidemiological properties, clinical findings, risk factors, direct microscopy and culture results in the patients diagnosed with microbial keratitis.

Materials and Methods: We examined the hospital records of patients with microbial keratitis between March 2016 and March 2021, retrospectively. Also, clinical findings, risk factors, microbiological results, empirical treatment and treatment responses were evaluated.

Results:42 eyes of 42 patients whose mean age was 57.8 (range 18-70 years) included in the study. In 12 (28.5%) patients, a gram positive and gram negative bacterial finding was found in the stained microscopic examination. In total, microbial growth was detected in culture of 7 patients (16.6%), while growth was not detected in 35 patients (83.4%). No etiological factor was detected in 27 patients (64.4%). The complaints at admission were pain in 24 patients (57.6%), redness in 12 patients (28.8%), and both redness and pain in 6 patients (14.1%).While the visual acuity of 18 cases were preserved after the treatment, 24 cases (88.8%) achieved 1 or more line with the treatment. While the mean visual acuity was 0.69 ± 1.1 (0-3.1) logMAR before treatment, it increased to 0.79 ± 1.1 (0-3.1) logMAR after treatment (p=0.006).

Conclusion: The keratitis is a common cause of unilateral blindness. Early diagnosis and treatment of the keratitis is a significant role on the prognosis. The success of the therapy can be provided starting empirical antimicrobial therapy by taking into consideration of the regional risk factors and common pathogens.

The health information system is a digital system that is quite complex so that in the development and evaluation stages, it is necessary to consider cultural, political, social and organizational structure factors. In Bali, the number of people with mental disorders is considered high and the need for treatment is in a fairly long time, that is the reason a management information system is needed to organize data and information about the patients. This study aims to develop a centralized management information system that can be utilised specifically for health workers to manage information regarding people with mental disorders. The development of the management information system in this study involves doctors, volunteers, and admin or organizational staff in every critical process. The prototyping method was chosen as a system development method because it considered more adaptive in capturing the needs of prospective system users.  At the evaluation stage, functional evaluation through the Black-box method was used to test the functional capabilities of the system. In addition, Technology Acceptance Model (TAM) and Task Load Index (TLX) were used to evaluate the non-functionality of the system where all users agree that the developed management information system is useful, easy to use, and requires a small cognitive workload.

Published: August 2023

Social media is an online media that users use to interact with each other by expressing themselves by giving comments, and one example is Instagram. All the collected comments will form a public opinion. This opinion can be used with sentiment analysis to become information. The method commonly used to carry out sentiment analysis is classification using machine learning. One of the machine learning that is often used is the Support Vector Machine (SVM). However, on non-linear problems such as sentiment analysis, SVM requires the kernel to map vectors into high-dimensional spaces to solve non-linear problems. The problem faced in using the kernel is to choose the optimal parameters for the classification model to produce a good classification model. This study proposes a new approach to obtain optimal parameters for SVM using Genetic Algorithm (GA). This study designed an SVM-GA classification model from the data collection, processing, classification, and evaluation stages. The results showed that the best accuracy produced with parameters optimized with the genetic algorithm was 81.6%, or an increase of 2.4% from the SVM sentiment analysis method without GA optimization.

The Family Hope Program (PKH) is a poverty alleviation program which is one of the government's strategies in reducing the poverty line. This program provides cash social assistance to poor families who are included in the list of beneficiary families with a focus on education and health. The purpose of implementing the PKH program is not only to reduce poverty and increase human resources but to break the poverty chain. The implementation of PKH in its realization experienced many obstacles that caused the program not to be on target, this was because the data verification process was not yet effective and was still carried out manually. A process is needed to digitize the distribution and realization of the family of hope program. Through this research, a system was developed that can predict the value of PKH beneficiary assistance. The system developed is based on machine learning with a prediction model using Artificial Neural Network (ANN) and Backpropagation learning algorithm. Parameters in the learning system using PKH assessment as many as 8 indicators from the data of PKH beneficiaries in Tabanan Regency. Based on the prediction model testing using two data treatments, namely with and without preprocessing data. Parameters treated with data on numeric attributes and categories provide optimal values with an R2 Score of 0.695824 with a number of hidden layers of 500 and a max epoch of 375

Published: August 2023

Mass communication through social media can be used as a link between political communicators and the public. As a political communication channel, social media can influence and determine political behavior because social media can influence public opinion. Good control of public opinion plays a role in winning the battle for societal influence. For political forces participating in parliamentary elections (such as presidential elections, regional head elections and members of parliament), it is important to use social media effectively to convey political messages. Through social media, the public absorbs the content of political messages more quickly and easily, because every public has access to information without barriers and geographical boundaries. Social media is also a very effective means of communication, especially when conveying information and receiving public feedback. Public feedback can bring closer relations between the political media and the public. In addition, the use of social media is increasingly popular and growing among people today, reaching even remote rural areas. With good information packaging, the public can easily understand the political messages conveyed by the political media. By conveying political messages that are appropriate and carried out effectively, in the end it can arouse public sympathy so that they accept the intentions desired by political communicators.

Serum TSA determinations were carried out by the resorcinol method.Results: In (positive group), the mean of TSA concentration (after hemodialysis treatment) was 68 ± 2.9 mg/dl, and the mean of TSA concentration in (negative group) was 110.7 ±7.5 mg/dl, while the mean TSA level in healthy control group was 58.3 ± 1.7 mg/dl. Also, this study aimed to assess serum concentration of immunoglobulins: IgG, IgM and IgA. Serum IgG was increased in patients of (positive group) and (negative group) with respect to control healthy (6.1, 5.5, 5.4 respectively) (p<0.05).There was no significant difference between the third groups in serum IgM concentration (6.6, 6, 6.2 respectively).Also in serum IgA concentration (5.8, 6, 5.5 respectively).Conclusion: We conclude that the TSA levels in the first groups both were found to be significantly elevated as compared to control levels (p<0.05), and Hepatitis C virus are linked to selective increase of serum IgG.

Participation in sports is identified in the UN Convention on the Rights of Persons with Disabilities as a fundamental right and is facilitated by the use of specialized Assistive Products (AP). However, little is known about the role everyday AP plays in promoting sport participation. Purpose: This study explores how the 50 priority APs on the World Health Organization’s Assistive Products List can promote participation in sports. Materials and methods: We used an online survey with AP-users, caregivers, and coaches (n=96). Subsequently, we performed a thematic analysis for qualitative responses describing the use of APs in facilitating sport participation. Results: Our results suggest everyday APs are required for sport participation for persons with disabilities. We present a conceptual model of AP use for sport participation. We found people with disability participate in a range of sports, contributing to community engagement. Conclusions: Access to everyday APs is integral to achieving the rights of persons with disabilities for participation in sport.

This communication will present an educative and research project that has linked the creation of 3D Assistive Technology (AT) for people with disabilities with the training of students of secondary education. STEMBach educational program aims to provide quality scientific education to secondary school students in the fields of science, technology, engineering, and mathematics (STEM) through research projects. Specifically, the text focuses on one project proposed by the TALIONIS research group, which uses 3D printers to design and create assistive technology (AT) for people with disabilities. The project involves students from eight different high schools and ten individuals with disabilities from four non-governmental organizations. The students design and print the AT using software such as Tinkercad and Cura Software. After testing the AT, outcome measurement instruments are used to validate their effectiveness. The project is based on a Learning-by-doing methodology with a structure of service-learning, and the involvement of the students is voluntary. The objectives of the project are to involve the students in research and innovation, to generate resources and AT for people with disabilities, and to determine the effects of AT on the lives of its users. Finally, the project leads to identifying new needs of people with disabilities that could be addressed through further research work.

There is a practical demand to maximise existing data to understand and meet the assistive technology (AT) needs in dynamic populations. Harmonisation can generate new insight by integrating multiple datasets that were not previously comparable into a single longitudinal dataset. We harmonised AT assessment data from three population-based surveys collected several years apart in Nepal: the Living Conditions of Persons with Disabilities (2014–2015), the Multiple Indicator Cluster Survey (2019), and the rapid Assistive Technology Assessment (2022). The harmonised dataset demonstrates a method that can be used for unifying AT surveys in other settings and conducting trend analyses that are necessary for monitoring a population’s dynamic AT needs. We set out to explore AT data’s potential for harmonisation, and learned there is indeed value in this approach for situating disparate datasets, though the methodology proposed will need further validation.

WHO implemented the Rapid Assistive Technology Assessment in 2021. This is a household survey on self-reported use, need and barriers for accessing AT in 35 countries globally. In order to obtain comparable data, all surveys followed guidelines developed by WHO, including national two-stage random sampling of households. The 2021 rATA survey included 32 of a total of 140 LMICs globally. Around 40 % of the total respondents (all countries) estimated travel distance to be <5 km, varying from less than 10 % to almost 60 % among the countries. Around 15 % had to travel more than 50 km, varying from 1.3 % to 37.5 %. More individuals living in rural as compared to urban areas had to travel more than 25 km to get their main assistive product. Gender differences were marginal. By far the most prevalent barrier to access assistive products was “Cannot afford”, amounting to 39.9% and varying from 6.7 % to 79.1 % among countries. This was followed by “No support” with 14.3 %, varying from 2.3 % to 36.9 %, and “Not available” with 8.1 %, varying from 1 % to 21.5 %. More barriers were reported in rural than urban areas and women report more barriers than men. Variation between countries in both travel time and barriers is substantial and country-specific service development is needed to guide service development.
Head Gesture Interface for Mouse Stick Users by AAGI

Published: August 2023

We developed a gesture interface (AAGI) for individuals with motor dysfunction who cannot use standard interface switches. These users have cerebral palsy, quadriplegia, or traumatic brain injury and experience involuntary movement, spasticity, and so on. In this paper, we describe a disabled user who utilizes a mouth stick for laptop PC input in daily life. Our objective is to lower the burden on his body by using gestures. To this end, we developed a “home position” for the head that enables gestures to coexist with the mouse stick usage. The results of basic experiments with five healthy participants indicate that our system has reached the level where it can be applied to actual disabled persons. Finally, we applied the system to a user with cerebral palsy asked him to perform web browsing.

The UN Convention on the Rights of Persons with Disabilities (UNCRPD) promotes the realisation of the right of persons with disabilities to education through Article 24 – Education. Universal Design in Education (UDE) fosters a whole systems approach so that the physical and digital environments, the educational services, and the teaching and learning can be easily accessed, understood and used, by the widest range of learners and by all key stakeholders, in a more inclusive environment. The whole systems approach incorporates the entire educational environment, as well as the recognition of the capacity for all learners (including persons with disabilities) to learn, and environments which are fully accessible and inclusive. This paper discusses methods whereby a systems approach can be applied to various aspects of education across the life continuum. It further advocates the inclusion of Universal Design as subject matter in curricula and assessment, to ensure a broader and more widespread adoption across the educational spectrum.

Published: August 2023

In the framework of the LTA project, focusing on leisure reading for children with visual impairment, we present a prototype of multisensory illustration that will be used as a model for future accessible tactile interactive books. This multisensory illustration is based on two approaches to illustrate the storytelling. The first approach consists in embodying the character’s legs with the index and middle fingers in order for the user to imitate actions such as walking. The second approach is to offer interactions feedback according to the readers actions. The main goal of this multisensory illustration prototype is to test and evaluate a selection of interactions and their associated sensors. These interactions help visually impaired readers to identify the environment of the story. They also help to understand actions behind the verbs. Readers are engaged to produce actions such as touching and imitating with their fingers. These interactions are developed according to hypotheses based on the literature. This multisensory illustration prototype was tested with a panel of children. The results comfort the idea that these interactions are useful for them.

Published: August 2023

Vehicular ad hoc networks (VANET) have been the attention gainer for the last couple of years due to increasing number of vehicles on the road. Incorporation of VANET with Internet of Things (IoT) has created large number possibilities in terms of power efficiency and secure transmission. The article focuses on the ad-hoc on-demand distance vector (AODV) protocol and its applications in route discovery in VANETs. In this work, the swarm intelligence (SI) inspired modified firefly algorithm has been employed for rank generation of the nodes. It is concluded that the use of IoT devices and advanced routing protocols with SI algorithms can lead to efficient and low-latency route discovery in VANETs using quality of service (QoS) parameters. The experimental analysis shown that the proposed technique has been outperformed the other existing technique in terms of QoS parameters and provides the optimal route discovery mechanism with high throughput and minimum latency.
