Authors: Mallavarapu Sandhya , Lokam Anjaneyulu 
Published: January 2023

Abstract
The paper introduces a compact, thin flexible textile antenna integrated with an Electromagnetic Bandgap (EBG) and Defected Ground Structure (DGS) covering the Wireless Local Area Networks (WLAN) bands (2.4-2.485 GHz and 5.1-5.9 GHz) for emergency services and responses. The geometry and configuration of the proposed antenna are made from common clothing jeans fabric, which makes the antenna more flexible, thin, and conformal. A new configuration of EBG structure is developed using Minkowski fractal geometry as base geometry and a DGS with the complementary dumbbell-shaped slot to operate in WLAN standards. The EBG structure is used to isolate the antenna from the human body, whereas the DGS is used to improve the bandwidth and polarization purity. The prototype covers the WLAN bands with gains of 3.37 dBi and 6.47 dBi, a bandwidth of 115.9 MHz, and 398.06 MHz for the specified wireless bands. The integrated antenna demonstrates a Front to Back Ratio (FBR) of 16.77 dB and 32.72 dB, the radiation efficiency of 36.9 % and 73.8 %, and a better cross-polarization level at 2.45 GHz, 5.85 GHz, respectively. The antenna shows a high gain and an efficiency of about 70 % under the various bending scenario. Thus, the anticipated antenna is the most appropriate and potential candidate for wearable applications in various domains.

Abstract
The developments of the fourth industrial revolution have caused changes in all areas of society, including production. The changes in production caused by the fourth industrial revolution have also resulted in fundamental changes in the supply chain and have converted it to supply chain 4.0. Organisations must be receptive to supply chain 4.0 to maintain their competitive advantage. Therefore, this study aimed to investigate the relationships among supply chain 4.0 technologies so that, by learning and understanding these connections, industries can pave the way for the implementation of these technologies in their supply chains and use them in problem-solving. The literature review was used to identify the supply chain 4.0 technologies, and the Delphi technique was applied to extract them, including the Internet of Things (IoT), cyber-physical systems, cloud computing, big data, blockchain, artificial intelligence, Radio-frequency Identification (RFID), augmented reality, virtual reality, and simulation. The relationships of supply chain 4.0 technologies were examined using the DEMATEL technique and based on interpretive structural modelling (ISM), their deployment map was drawn. The type of technologies was determined using the MICMAC method. The MICMAC analysis found that the artificial intelligence technology is independent and, based on the findings through the DEMATEL technique, this technology is related to simulation, which belongs to the first level of the interpretive structural modelling technique, and IoT, cloud computing, big data, and blockchain technologies, which are at the second level. Based on the ISM method, RFID, virtual reality, augmented reality and simulation technologies are located at the first level; IoT, cyber-physical systems, cloud computing, big data and blockchain technologies are situated in the second level; and artificial intelligence technology belongs to the third level. According to the related literature, few studies have been conducted on the issues of supply chain 4.0 and the technologies that affect it.
An approach for semi-automated data quality assurance within BIM models
Authors: Cann Steven , Mahamadu Abdul-Majeed , Prabhakaran Abhinesh , Dziekonski Krzysztof , Joseph Rotimi 
Published: January 2023

AbstractSuccessful Building Information Modelling (BIM) enabled projects that require large volumes of project data to be embedded within BIM models. However, with this wealth of data, relevance and accuracy have been identified as important issues affecting the BIM performance of the project. Currently, Quality Assurance (QA) in the industry has focused on geometric data, including scrutinising physical and spatial clashes. However, as BIM practices progress in the industry, the requirements for nongeometric model data and their quality have become more necessary. This study aimed to ascertain the feasibility of using visual programming for semi-automating the BIM QA process in a practical case study on using BIM in infrastructure projects. This paper outlines a generic semi-automated QA methodology and its application in a construction project case study. The validity of this method was tested and evaluated in practice through (n=2) workshops. The methodology was implemented within an integrated engineering consultancy, employing visual programming methodology to generate QA summaries and additionally highlight model elements with data quality issues based on a defined set of parameters. Based on the evaluation findings, the proposed process was feasible and provided a pathway for low-cost and low-skill QA of BIM model data within the architecture, engineering and construction (AEC) industry. The paper’s main scientific contribution is a conceptual framework for using visual programming to achieve automatic quality assurance.
Sustainability of the Currency Board in Bosnia and Herzegovina in the Conditions of a Negative Interest Rate on the Reserve Currency
Authors: Tomaš Rajko 
Published: January 2023

Abstract
The Currency Board in Bosnia and Herzegovina (BiH) uses the euro as a reserve currency in the conditions of a negative nominal interest rate on deposits with the ECB. In this paper, we investigated the impact of negative interest rates on deposits and negative yields on bonds denominated in euro on the general advantages of the currency board and the consequences for the functioning of the currency board in BiH. The impact of negative interest rates was measured by the currency board coverage index (IC). A negative nominal interest rate on the reserve currency creates a negative seigniorage in the country of the currency board, increases the costs of issuing domestic money and reduces the competitiveness of the economy. The monetary policy of the ECB in the conditions of the COVID-19 crisis generates negative influences on the functioning of the currency board. The COVID-19 crisis poses a threat to currency board coverage in BiH. Technically, a currency board can also function in terms of negative interest on the invested reserve currency as long as it can cover the costs of its business.

Authors: Carr Amanda Nicole , Kirkwood Roy Neville , Petrovski Kiro R. 
Published: January 2023

Abstract
This article, part 2 of a 2-part series, describes the next two steps in the application of the Modified Calgary-Cambridge Guides (MCCG) to consultations in bovine medicine, ‘explanation and planning’, and ‘closing the consultation’, and introduces concepts that are associated with all the components of the guide, ‘building the relationship with the client’ and ‘providing structure to the consultation’. Part 1 introduced the aim and framework of the MCCG which enables the practitioner to gain an insight into the client’s understanding of the problem, including understanding aetiology, epidemiology and pathophysiology. Part 2 introduces the framework that provides the opportunity to understand the client’s expectations regarding the outcome, their motivation and willingness to adhere to recommendations. It also describes how to engage and acknowledge the client as an important part of the decision-making process, how to establish responsibilities of both the client and practitioner, and how to reach out to the client at the conclusion of the consultation to make certain that the client’s expectations were met.
CONCEPT as a Travelling Concept in Subject-Matter Teaching and Learning
Authors: Bohlmann Markus 
Published: January 2023

Abstract
Research on students´ concepts based on conceptual change theory is being conducted in relation to more and more different subject content. CONCEPT, the concept of a concept, however, has very different meanings and functions in different contexts of subject-matter teaching and learning. In this study tools of analytic philosophy of science and philosophy of cognition are applied to examine the recent process of a research transfer from science education to philosophy education. Transmutations of CONCEPT are evident in empirical studies in philosophy education. However, such a transfer process can reveal problems of CONCEPT that affect any subject- matter research on student´s concepts. Three main problems are shown: a problem that is new to philosophy education, one that is a legacy of science education, and another, future problem that is emerging with conceptual engineering. The solution to these problems could lie in an integrated interdisciplinary project, the theoretical determination of subject-matter CONCEPT.

Abstract

Background: Apolipoprotein E (ApoE) is a ubiquitous protein involved in maintaining cholesterol homeostasis and lipoprotein clearance from circulation. It is coded by three alleles (ε2, ε3, ε4) with six genotypes (ε3/ε3, ε3/ε4, ε2/ε3, ε4/ε4, ε2/ε4, and ε2/ε2). Several studies have shown a relationship between ApoE-specific isoforms and different diseases. There are few data about the prevalence of ApoE polymorphism in the Romanian population. We aimed to assess the prevalence of Apolipoprotein E alleles in a healthy population from Romania and compare it with the data found in other countries of Europe.

Methods: ApoE genotype was examined in 187 unrelated healthy volunteers (131 males and 56 females) from the region of southwest Romania (mean age 48.04 ± 8.35 years). Analysis of ApoE genotype variants was done using the PCR method with allele-specific oligonucleotide primers.

Results: The frequency of heterozygote genotypes ε2/ε3, ε2/ε4, and ε3/ε4 was 4.8%, 1.6%, and 24.73%, respectively, while the frequency of homozygote genotypes ε2/ε2, ε3/ε3, ε4/ε4 was 0.5%, 66.12%, and 2.1%, respectively, with a mean frequency of ε2, ε3 and ε4 alleles of 6.9%, 96.25%, and 28.49%, respectively. East European countries have the lowest mean frequency of the ε4 allele (9.96%), and the highest frequency of the ε4 allele (23.38%) is in the Nordic Countries.

Conclusions: The ε4 allele prevalence in this Romanian population is higher in comparison with other European countries, similar to Nordic countries of Europe.

Strategy Development in the Service of Railway Undertakings
Authors: Nedeliaková Eva , Valla Michal 
Published: January 2023

Abstract
Railway undertakings face many challenges and obstacles to competition in the transport market. Strategic management methods in relation to quality assurance of services provided by carriers, used not only in transport sectors but also in industrial sectors, are a way to continuously improve the quality of services and thus the competitiveness of railway undertakings. Nowadays, customers are becoming more and more demanding, also in view of the wider range of services offered by other modes of transport. For this reason, quality requirements are increasing. Most business strategy evaluation systems are only partial, limiting themselves to the assessment of certain factors where many shortcomings remain hidden. In the same way, a strategic plan for the economic growth and development of a transport organisation does not always ensure the achievement of the set objectives.

Authors: Sardjono Michelle , Dhani Dhevariza Pra 
Published: January 2023

Sindrom kompartemen merupakan kasus yang paling banyak ditemui pada populasi pediatrik dengan insiden tertinggi terjadi pada rentang usia 10 hingga 14 tahun. Hal ini dikarenakan rasio massa otot terhadap ukuran kompartemen relatif lebih tinggi dan struktur fasia yang lebih kuat mengurangi kemampuan kompartemen untuk mengakomodasi peningkatan pembengkakan yang signifikan. Kegagalan untuk menangani sindrom kompartmen dengan cara yang cepat dapat menyebabkan cacat permanen (kontraktur otot) pada anggota tubuh yang terkena. Studi ini memaparkan sindrom kompartemen setelah fraktur antebrachii pada seorang anak laki-laki usia 8 tahun. Pasien datang dengan keluhan nyeri pada lengan kiri sehingga sulit digerakkan. Pasien mengatakan terjatuh dari pagar 2 hari sebelum masuk rumah sakit dan sempat dibawa ke tukang urut. Lengan dan tangan kiri bertambah bengkak disertai lenting-lenting kecil berisi air. Pasien datang dalam kondisi diperban dengan lilitan kencang. Pasien diduga mengalami sindrom kompartemen. Pemeriksaan fisik: pasien tampak sakit sedang, kesadaran compos mentis (E4V5M6), tekanan darah 100/80 mmHg, frekunsi napas 20 x/menit, denyut nadi 71 x/menit, suhu tubuh 36,50 C. Pada regio dorsum manus et antebrachii sinistra didapatkan jejas, edema, bula, mengkilap, pallor, hangat, pain, pressure, parasthesia, pulselessness, paralysis. Pemeriksaan CT-scan didapatkan fraktur 1/3 proximal os radius sinistra dengan displace fracture, fraktur 1/3 tengah os ulna sinistra dengan displace fracture, dan soft tissue swelling daerah lesi. Pasien diberikan terapi farmakologi berupa Ringer Lactate 500 cc per 24 jam, cefotaxime 2 x 1 gram, dan paracetamol 3 x 500 mg serta terapi non-farmakologi berupa debridemen dan pemasangan spalk di bagian bawah sebagai alas.

Background:
Anorexia Nervosa is a life-threatening mental illness with numerous consequences. Some cases are chronic and refractory to multiple treatments. Consequently, there is great interest in therapeutic alternatives that may improve severe patients. We present an adult patient with anorexia nervosa that underwent to bilateral nucleus accumbens deep brain stimulation (NAc-DBS).

Case description:
The patient was a healthy 46-year-old woman with higher education and an adequate premorbid socio-labour situation. Her disease had a late onset (25 years). The patient never presented clinical remission or weight stability. In recent years, the patient’s body mass index (BMI) was 13.16 (32kg). The case was evaluated with multiple neuropsychological tests as well as the BMI before and after surgery. The clinical follow-up was 50 months. After bilateral NAc-DBS the patient experienced an important clinical benefit and significant improvement in neuropsychological tests and weight (BMI 17.28, 42 kg; 50th month) Programming: 4,5V, 130Hz, 210 µs.

Conclusion:
Despite the patient´s age and the long duration of the disease, our results suggest that bilateral nucleus accumbens stimulation may be a useful and effective therapeutic strategy for cases such as the one presented. Additionally, this case presents a surgical midlife patient with both the latest disease onset and the longest follow-up after treatment in the literature.

Published: January 2023

Background:
A decompressive craniectomy (DC) is a surgical procedure sometimes utilized to manage refractory intracranial hypertension following severe traumatic brain injury (sTBI). The previous studies have established a relationship between DC and post traumatic hydrocephalus (PTH). This study aimed to identify the factors responsible for developing shunt-amenable PTH in patients who underwent DC following sTBI.

Methods:
A review of a prospectively collected database of all patients admitted with severe TBI in a tertiary neurosurgical center in North-west England between January 2012 and May 2022 was performed. PTH was defined as evidence of progressive ventricular dilatation, clinical deterioration, and/or the eventual need for cerebrospinal fluid diversion (i.e., a ventriculoperitoneal shunt). Statistical analysis was carried out using IBM SPSS versus 28.0.1.

Results:
Sixty-five patients met the eligibility criteria and were included in the study. The mean age of the PTH group was 31.38 ± 14.67, while the mean age of the non-PTH group was slightly higher at 39.96 ± 14.85. No statistically significant difference was observed between the two groups’ mechanisms of traumatic injury (P = 0.945). Of the predictors investigated, cerebellar hematoma (and contusions) was significantly associated with PTH (P = 0.006).

Conclusion:
This study concludes that cerebellar hematoma (and contusions) are associated with developing PTH in patients undergoing DC.

Published: January 2023

Sebagian besar wilayah Indonesia adalah perairan laut dengan luas meliputi dua pertiga luas wilayah negara. Survei hidrografi menggunakan multibeam dinilai lebih efektif dan efisien dalam mengeksplorasi laut terutama kondisi dasar laut apabila dibandingkan dengan single beam echosounder. Perairan Teluk Jakarta yang dangkal dengan kegiatan maritim yang padat terutama arus lalu-lintas pelayaran memerlukan pemahaman yang kritis dan spesifik untuk menjaga keselamatan navigasi di laut. Untuk itu diperlukan standar survei dalam pengambilan dan pengolahan data multibeam yaitu aturan standar berdasarkanInternational Hydrographic Organization (IHO) yang memuat kalibrasi patch test, kalibrasi offset statik, koreksi pasang surut, dan koreksi kecepatan rambat suara dalam air dan uji kualitas data. Data multibeam yang diperoleh telah dikalibrasi dan dikoreksi dengan hasil uji kualitas pada orde spesial sebesar 97.47%. Pengukuran multibeam menghasilkan data kedalaman maksimum perairan Teluk Jakarta sebesar 10.92 m, kedalaman minimum sebesar 5.84 m, dan rata-rata kedalaman 8.26 m. Interpretasi morfologi dan topografi dasar laut membentuk alur cekungan seperti parit dengan asumsi hasil pengerukan atau erosi. Analisis data kedalaman menunjukkan terdapat area pendangkalan di sisi barat daya cekungan dengan diperoleh adanya dua titik kedangkalan.
