Published: August 2022

Latar Belakang: Surabaya dengan kepadatan penduduk, dapat menimbulkan permasalahan apabila tidak dikelola dengan baik salah satunya bidang kesehatan. Pelayanan administrasi yang berbelit-belit dan tumpukan antrean pada fasilitas pelayanan kesehatan merupakan dampak permasalahan yang sering ditemukan, hal tersebut yang melatarbelakangi e-health diterapkan di Surabaya
Tujuan: mengkaji penerapan e-health dan dampaknya di fasilitas pelayanan kesehatan kota Surabaya
Metode : Penelitian ini merupakan studi literature review. Sumber data berasal dari google scholar dan portal garuda dari rentang waktu 2016-2022. Kata kunci yang digunakan e-health di Kota Surabaya. Hasil keseluruhan artikel melalui screening berjumlah 15 artikel
Hasil:. Sejarah e-health diciptakan karna antrean yang terjadi pada fasilitas pelayanan kesehatan. Indikator menunjukkan bahwa e-health berdampak pada pengurangan antrean di fasilitas pelayanan kesehatan apabila tidak digunakan secara manual, pemerataan sarana prasarana dan sosialisasi juga perlu lebih dilakukan. Keberadaan petugas pendamping dan pelatihan bagi petugas pelayanan perlu dilakukan untuk menunjang kepuasan pada masyarakat
Kesimpulan: e-health telah diterapkan di 65 fasilitas pelayanan kesehatan, namun tidak semua menerapkan dengan baik. Sebagian fasilitas pelayanan masih menerapkan secara manual sehingga antrean masih terjadi. Dampak pada fasilitas pelayanan yang menerapkan antrean dapat berkurang dan memudahkan baik bagi masyarakat maupun petugas layanan karna dimudahkan dalam penyimpanan data pasien. Faskes disarankan melakukan inovasi sosialisasi agar masyarakat lebih mengetahui keberadaan e-health.

Objective: The COVID-19 disease, which first appeared in Wuhan, China, at the end of 2019, soon affected the whole world. This study aims to examine the relationship between the demographic characteristics and clinical symptoms of COVID-19 patients and mortality rates during the COVID-19 pandemic period.
Material and Methods: This retrospective observational study was done on the files of 671 dead or living patients with laboratory-confirmed COVID-19 pneumonia hospitalized in Sinop State Hospital in Turkey from February to September of 2020. The demographic features such as sex, age, and comorbidities such as diabetes, hypertension, etc., and clinical symptoms of the disease such as fever, cough, shortness of breath, respiratory distress, weakness, head rotation, etc., were recorded.
Results: The total mean age of the patients was 56.08 years. The most common symptoms were cough, fever, respiratory distress, shortness of breath, and the most common comorbidities were hypertension, diabetes, ischemic heart disease, and COPD. There was a statistically significant difference between the dead and living patients in terms of sex (p=0.011, EXP(B)=0.429), cough (p=0.000, EXP(B)=0.137), and respiratory illness (p=0.000, EXP(B)= 15.526). There was a statistically significant difference between the dead and living patients in terms of age, number of additional illness, number of arrival complaint, length of stay in the hospital, intensive care hospitalization period, and number of medications used (p-values=0.000, 0.040, 0.000, 0.020, 0.030, and 0.000, respectively).
Conclusion: As a result of our study, gender, cough, and respiratory tract disease were statistically effective factors for course of illness. In addition, there was a significant difference between living and deceased patients in terms of age, number of additional diseases, number of admission complaints, length of hospital stay, length of stay in the intensive care unit, and number of drugs used. According to these results, it has been concluded that COVID-19 patients with these factors should be followed more carefully.

Published: August 2022

In this paper computer studies of the effectiveness of using transfer learning methods to solve the problem of recognizing human brain tumor based on MRI images were performed. The deep convolutional networks VGG16, ResNet50, InceptionV3, Xception, DenseNet121 and MobileNet_v2 were used as the basic pretrained models. Various training and finetuning strategies for deep convolutional networks for recognizing brain tumor are proposed. An analysis of their performance showed that the strategy of finetuning of the Xception model on an extended MRIscans data set yielded higher accuracy, precision, recall and AUC metrics compared to the other models. The best classification achieved accuracy on the Xception finetuned model is 98%.
Uterine natural killer cells and successful pregnancy: from mouse experiments to human physiology
Authors: Faas Marijke M.
Published: August 2022

Uterine natural killer (uNK) cells, a specific type of natural killer (NK) cells, are important cells at the foeto-maternal interface in humans as well as in mice. uNK cells are part of the innate lymphoid cells group 1. Especially in the mouse, but also in the rat, many in vivo studies have been performed to evaluate the role of uNK cells in placental development. These studies have shown that uNK cells are not indispensable to pregnancy, but that they play an important role in optimal decidual angiogenesis in early pregnancy, trophoblast invasion and spiral artery remodelling in the mouse placenta. Based on the mouse studies, various in vitro studies, as well as immunohistological studies of the human placenta from elective abortions, have shown that uNK cells have similar functions in the human placenta. In the present narrative review, the role of the uNK cells in the development of the mouse and rat placenta will be discussed first. Thereafter, studies on the role of human uNK cells in the human placenta will be reviewed and these studies will be discussed in the light of the knowledge on mouse uNK cells.
The human microbiome and the tumor microenvironment
Authors: Murphy Joseph F.
Published: August 2022

The human microbiome has emerged as an intriguing field of scientific research. Its role in human physiology impacts both health and disease, contributing to the enhancement or impairment of metabolic and immune functions. Sometimes referred to as our body’s “second genome”, the alteration of the microbiome’s bacterial ecology (dysbiosis), is linked to increasing numbers of illnesses, including cancer. The tumor microenvironment (TME) is the environment in which tumors grow and modulate the tumorigenic process depending on a myriad of distinct factors, including cell types, vascular system, and cytokines. Given the emerging relationship between the microbiome and the TME, this perspective aims to distill some of the key factors regulating the crosstalk between the microbiome and the TME. It also outlines why manipulating the microbiome may be a feasible strategy for anti-cancer therapy.

Frustration and ennui among Amazon MTurk workers
Authors: Fowler Craig , Jiao Jian , Pitts Margaret
Published: August 2022

Academics are increasingly turning to crowdsourcing platforms to recruit research participants. Their endeavors have benefited from a proliferation of studies attesting to the quality of crowdsourced data or offering guidance on managing specific challenges associated with doing crowdsourced research. Thus far, however, relatively little is known about what it is like to be a participant in crowdsourced research. Our analysis of almost 1400 free-text responses provides insight into the frustrations encountered by workers on one widely used crowdsourcing site: Amazon’s MTurk. Some of these frustrations stem from inherent limitations of the MTurk platform and cannot easily be addressed by researchers. Many others, however, concern factors that are directly controllable by researchers and that may also be relevant for researchers using other crowdsourcing platforms such as Prolific or CrowdFlower. Based on participants’ accounts of their experiences as crowdsource workers, we offer recommendations researchers might consider as they seek to design online studies that demonstrate consideration for respondents and respect for their time, effort, and dignity.

Published: August 2022

This research investigated the connection between the entrepreneurial mindset of telecommunications companies in Rivers State, Nigeria, and their level of market competitiveness. In the state of Rivers, there were a total of 139 managers working for four different telecommunications companies: MTN, 9Mobile, Airtel, and Globacom. The researchers used a straightforward random selection method to choose 103 participants for their investigation. The delivery of a structured questionnaire was used to obtain the primary data for this study. Using Spearman's Rank Order Correlation Coefficient and the Statistical Package for the Social Sciences (SPSS) version 22.0, we examined whether or not the provided hypotheses were supported by the data. According to the findings of the research, the two aspects of entrepreneurial orientation that were chosen (innovativeness and proactiveness) have a substantial connection to an organization's level of competitiveness (quality and market share). According to the findings of the study, the management of telecommunications companies should have an innovative plan to fund innovative ideas, experimentation, and creative processes; they should also introduce new products and services; and they should invest significantly in research and development. Additionally, the management of companies that deal in telecommunications have to take the initiative in the launch of new goods and services whenever possible. When it comes to the current state of the telecommunications industry, they should be recognized as a reputable brand. They should also react more quickly than their rivals do to educational and research opportunities.
Development of Wind Turbine Generator and Solar Hybrid Power System Model for Rural Electrification
Authors: Oshin Ola Austin
Published: August 2022

The countries that are most energy-consuming, where there are industrial developments, where the energy demand is highest are the advanced and developing countries in the world (Mustafa, 2018). For instance, the average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average power per capital (watts per person) in Nigeria is 14 W per person. (Austin, O. O et.al, 2020). Also, power supply in many parts of Africa is erratic and characterized with a lot of faults and outages. In Nigeria, it is estimated that only 40 % of Nigerians are connected to the national grid and the connected population are exposed to frequent power outages (Abubakar et al, 2015, Austin O.A, 2020). Unfortunately, the effects of incessant power supply have destroyed many industrial activities, reduced employment and has increased crime activities in many parts of the continent (Africa). Therefore, in order to provide urgent solution to these problems and satisfy the high energy demand in African residential and industrial environments, electrical energy should be reliable, aﬀordable, effective, and sustainable. This calls for an urgent establishment of alternative Renewable Hybrid Power Supply System which will provide continuous, reliable and effective power supply to the consumers.

Published: August 2022

Background:Simulation-based nano biosensors have been introduced in recent times that will provide a model for the researchers to verify various critical functions of them, which could effectively save time, money, and effort.Materials and Methods:In this study, we have performed simulations of a silicon nanowire (Si-NW) biosensor, and its various parameters were evaluated. This silicon sensor was designed using the BiosensorLab tool, a simulator from the nanohub website. This paper also presentedan Integrated Smart Bio-nano Sensor. The motivation behind this smart sensor was that an incident happened in one of the southern states of India, in the year 2020; the leakage of styrene gas (C8H8) from the Polymers industry caused 12 deaths and several people hospitalized. Most people died after they inhaled styrene gas because they thought the pungent smell (of styrene gas) was also part of their kitchen’s emissions. This incident prompted us to propose an Integrated Smart Bio-nano Sensor. Results:The proposed sensor was capable of classifying the origin of sources of emissions dynamically (smart), even under lower concentrations of gas levels (25 ppm) and could alert the habitants in case of untoward danger. Conclusions:After verifying settling time vs. analyte concentration, the density of captured target molecules concentration with time vs. time, and the signal-to-noise ratio (SNR) of the biosensor in the presence of parasitic molecules vs. receptor density, it was concluded that these three parameters have helped in identifying the characteristics of the proposed bio-nano sensor.

Published: August 2022

Brackets are generally debonded and remaining adhesive is removed at the end of the orthodontic treatment. There are different methods for adhesive removal of which few methods have a chance of damaging enamel and roughen the tooth surface which can lead to plaque accumulation, discolouration, and aesthetic problems. Enamel polishing after debonding is one strategy to decrease such consequences. Severalenamel cleaning and polishing methods include Sof-Lex discs, TC burs, ultrasonic tools, hand instruments,rubbers, composite burs, Arkansas stones, green stones, diamond burs, steel burs and lasers. Each method has some advantages and some lacunae. To be precise soflex discs and TC burs have less damage on enamel than other methods, i.e., Arkansas stone and greenstone. This article is a review of available different enamel cleaning and polishing methods after debonding, their advantages and disadvantages.

Authors: Wilson Teena , Ravichandran R  , Kumar K Harsha , V Nair Vivek
Published: August 2022

Any prosthodontic procedure aims to restore a patient's function, contours, aesthetics, speech, and health to normal. In traditional complete dentures, achieving optimal denture stability is always found to be a challenge. This is often exacerbated in resorbed mandibular ridges. Therefore, this article describes a strategy for enhancing the retention of mandibular complete dentures for individuals with an extremely resorbed ridge. A patient reported to the department of prosthodontics with a chief complaintof loose dentures and wanted to get them replaced. A complete clinical examination was carried out which revealed severely resorbed mandibular ridge. After a complete evaluation, prosthetic rehabilitation with a complete denture using the neutral zone technique was panned. The complete denture was made and delivered to the patient was superior in terms of stability, function and aesthetics. The clinician should understand the advantages of the neutral zone technique and implement it in clinical practice sothat a prosthesis that is functionally, physiologically and psychologically acceptable to the patient can be delivered.

Authors: Dib Jony , Khalil Majd , Chbib Joyce , Hamdan Manal
Published: August 2022

Background: Brain abscesses are intracerebral infections with pus accumulation that can be fatal in most cases without appropriate treatment. The most common cause of brain abscesses are infections with streptococci and staphylococci. Streptococcus anginosus is a group of streptococci that are part of the normal flora of the oropharynx and are rarely the cause of severe bacterial infections.
Case Report: Our patient is a 64-year-old man who underwent a dental procedure, and presented a few days later with a high-grade fever and decreased level of consciousness. He was found to have multiple brain abscesses and a liver abscess, and blood cultures revealed Streptococcus intermidius, which belongs to the Streptococcus anginosus group. The patient received appropriate treatment and recovered completely.
Conclusion: Dental procedures, even simple tooth brushing, can cause bacteremia leading to multiple abscesses in different parts of the body, especially if a germ of the Streptococcus anginosus group has been detected in the blood culture.
Antaeus: A Retrograde Group of Tidal Debris in the Milky Way’s Disk Plane

Published: August 2022

We present the discovery of a wide retrograde moving group in the disk plane of the Milky Way using action-angle coordinates derived from the Gaia DR3 catalog. The structure is identified from a sample of its members that are currently almost at the pericenter of their orbit and are passing through the solar neighborhood. The motions of the stars in this group are highly correlated, indicating that the system is probably not phase mixed. With a width of at least 1.5 kpc and with a probable intrinsic spread in metallicity, this structure is most likely the wide remnant of a tidal stream of a disrupted ancient dwarf galaxy (age ∼12 Gyr, 〈[Fe/H]〉 ∼ −1.74). The structure presents many similarities (e.g., in energy, angular momentum, metallicity, and eccentricity) with the Sequoia merging event. However, it possesses extremely low vertical action J

z

, which makes it unique even among Sequoia dynamical groups. As the low J

z
may be attributable to dynamical friction, we speculate that these stars may be the remnants of the dense core of the Sequoia progenitor.

Published: August 2022

In the first billion years after its formation, the Galaxy underwent several mergers with dwarf satellites of various masses. The debris of Gaia-Sausage/Enceladus (GSE), the galaxy responsible for the last significant merger of the Milky Way, dominates the inner halo and has been suggested to be the progenitor of both the Hercules-Aquila Cloud (HAC) and Virgo Overdensity (VOD). We combine SEGUE, APOGEE, Gaia, and StarHorse distances to characterize the chemodynamical properties and verify the link between HAC, VOD, and GSE. We find that the orbital eccentricity distributions of the stellar overdensities and GSE are comparable. We also find that they have similar, strongly peaked, metallicity distribution functions, reinforcing the hypothesis of common origin. Furthermore, we show that HAC and VOD are indistinguishable from the prototypical GSE population within all chemical-abundance spaces analyzed. All these evidences combined provide a clear demonstration that the GSE merger is the main progenitor of the stellar populations found within these halo overdensities.

Authors: Zarin Rahat , Khan Amir , Kumar Pushpendra , Humphries Usa Wannasingha
Published: August 2022

In this research, we reformulate and analyze a co-infection model consisting of Chagas and HIV epidemics. The basic reproduction number $ R_0 $ of the proposed model is established along with the feasible region and disease-free equilibrium point $ E^0 $. We prove that $ E^0 $ is locally asymptotically stable when $ R_0 $ is less than one. Then, the model is fractionalized by using some important fractional derivatives in the Caputo sense. The analysis of the existence and uniqueness of the solution along with Ulam-Hyers stability is established. Finally, we solve the proposed epidemic model by using a novel numerical scheme, which is generated by Newton polynomials. The given model is numerically solved by considering some other fractional derivatives like Caputo, Caputo-Fabrizio and fractal-fractional with power law, exponential decay and Mittag-Leffler kernels.
Rough set models in a more general manner with applications
Authors: Hosny Mona , Al-shami Tareq M.
Published: August 2022

Several tools have been put forth to handle the problem of uncertain knowledge. Pawlak (1982) initiated the concept of rough set theory, which is a completely new tool for solving imprecision and vagueness (uncertainty). The main notions in this theory are the upper and lower approximations. One of the most important aims of this theory is to reduce the vagueness of a concept to uncertainty areas at their borders by decreasing the upper approximations and increasing the lower approximations. So, the object of this study is to propose four types of approximation spaces in rough set theory utilizing ideals and a new type of neighborhoods called "the intersection of maximal right and left neighborhoods". We investigate the master properties of the proposed approximation spaces and demonstrate that these spaces reduce boundary regions and improve accuracy measures. A comparative study of the present methods and the previous ones is given and shown that the current study is more general and accurate. The importance of the current paper is not only that it is introducing new kinds of approximation spaces relying mainly on ideals and a new type of neighborhoods which increases the accuracy measure and reduces the boundary region of subsets, but also that these approximation spaces are monotonic, which means that it can be successfully used to evaluate the uncertainty in the data. In the end of this paper, we provide a medical example of the heart attacks problem to show the efficiency of the current techniques in terms of approximation operators, accuracy measures, and monotonic property.
Automatic arrhythmia detection with multi-lead ECG signals based on heterogeneous graph attention networks
Authors: Zhong MingHao , Li Fenghuan , Chen Weihong
Published: August 2022

Automatic arrhythmia detection is very important for cardiovascular health. It is generally performed by measuring the electrocardiogram (ECG) signals of standard multiple leads. However, the correlations of multiple leads are often ignored. In addition, an extensive and complex feature extraction process is usually needed in most existing studies. Therefore, these challenges will not only lead to the loss of overall lead information, but also cause the detection performance to depend on the quality of features. To solve these challenges, a novel multi-lead arrhythmia detection model based on a heterogeneous graph attention network is proposed in this paper. We have modeled the multi-lead data as a heterogeneous graph to integrate diverse information and construct intra-lead and inter-lead correlations in multi-lead data, providing a reasonable and effective the data model. A heterogeneous graph network with a dual-level attention strategy has been utilized to capture the interactions among diverse information and information types. At the same time, our model does not require any feature extraction process for the ECG signals, which avoids out complex feature engineering. Extensive experimental results show that multi-lead information and complex correlations can be well captured, thus confirming that the proposed model results in significant improvements in multi-lead arrhythmia detection.
Initial construction evidence of the Bou Ferrer shipwreck, a large vessel of the Early Roman Empire
Authors: de Juan Carlos , Cibecchini Franca
Published: August 2022

We present a basic summary of the research conducted on the Bou Ferrer shipwreck since 2006, which has provided interesting new data about a navis oneraria well dated to the second half of the 1st century AD. Despite that fact that only one major trench was excavated up until 2017, about 55 m2 of wooden structures in a good state of preservation have been revealed, providing information about her construction. There are construction elements that may be considered common for Roman Period wrecks, as well as others with fewer archaeological parallels. The presence of a double garboard is not unprecedented in the 1st century AD, but deserves further study. Many hull pieces, from the lower wale to another that we consider as an upper wale, are sufficient elements to propose a preliminary measurement of width amidships. These lines, combined with the stowed amphorae carrying fish sauces, open the possibility that a third perishable cargo might also have been transported.
The hopper barges of Marseilles
Authors: Corré Xavier
Published: August 2022

The archaeological excavations of Place Jules-Verne in Marseille, France, at the beginning of the 1990s revealed three ancient sister­ships (JV3, JV4 and JV5) abandoned near the shoreline around AD 100. These shipwrecks feature a central cavity, which made them difficult to identify. Medieval sources have now helped us to identify them as hopper barges designed to pickup sludge from the bottom of the harbour and to carry and dump it in another place by means of a ‘door’ we can now reconstruct in the bottom of the barge hull.

During 2016, several undocumented shipwreck sites were exposed on the sandy shores of Halland, western Sweden. One of the most interesting finds is situated in the shallow bay of Korshamn, close to the medieval town of Falkenberg. A limited test excavation revealed a clinker-built vessel over 13 m long. Dendrochronological analysis suggests that the vessel was built shortly after 1168 from Scandinavian wood. Even though it clearly conforms to contemporaneous Scandinavian ship building practices, there are certain features that appear highly unusual. This paper presents the preliminary results of the excavation. In addition, the kar phenomenon of southern Scandinavia is briefly discussed.

Among the finds was BSMAP_2016_STR_WRK_002, a vessel dated to the end of the 9th or beginning of the 10th century AD. This paper offers a preliminary description of the find.
The Oseberg ship: reflections on the choice of methodology when testing experimental archaeological reconstructions
Authors: Bischoff Vibeke
Published: August 2022

Saga Oseberg, a full-scale reconstruction of the Oseberg ship, has been tested using different approaches. First, the principles employed for handling traditional square-rigged boats from Norway were applied. The ship manoeuvred badly, and this was taken as proof that the reconstruction was incorrect. Subsequently, a new programme of test sailing was undertaken using a more investigative approach to the full-scale reconstruction, resulting in a marked improvement in the ship’s performance. This paper will present an outline of the methods used, posing critical questions as to the application of more recent sailing traditions to the handling of archaeological reconstructions: is it possible to set one’s preconceptions aside to let replicas ‘speak’ for themselves?
An attempt to create a digital reconstruction of the Puck 2 wreck hull
Authors: Litwinienko Paweł , Różycki Janusz
Published: August 2022

This paper focuses on the process of documentation and digital reconstruction of the Puck 2 wreck, salvaged in 2005 from an early medieval harbour in the Puck Lagoon, northern Poland. After PEG treatment the wreck timbers were digitally documented according to the methodology developed during the Newport ship project. The individual timbers were then assembled using Rhinoceros software into a virtual model of the wreck as found, which served as a base for the attempted reconstruction of the ship’s hull and its hydrostatic characteristics.
Mass documentation of archaeological ship timbers: introducing a novel, time-efficient approach
Authors: Van Damme Thomas , Ditta Massimiliano , Auer Jens
Published: August 2022

This article introduces the annotated scans method as a new approach to ship timber recording. The proposed method consists of several phases: timbers are first scanned in 3D, these scans are then annotated in Rhino, and finally the timber catalogue is generated using a semi-automated workflow. We compare this approach to the current best practice method for timber recording, namely contact digitising. Based on our experience recording the timbers of the Wismar “Big Ship”, we conclude that the proposed method matches, and in some regards surpasses the current best practice method, most notably in terms of cost and time efficiency.
Traditional ship construction in the Gulf of Lion and the Ligurian Sea: the tartane case study
Authors: Botcazou Hélène
Published: August 2022

This article deals with a type of coaster from the northwest Mediterranean called tartane. This emblematic coaster is generally presented as the most commonly utilised boat for cargo transport from the 16th century until the end of sailing ship coastal trade in this area at the very beginning of the 20th century. Although it is often described as a wide-bottom one-masted lateen ship, we can count at least four different rigging systems in various iconographic resources portraying tartanes, dating from 1679 to the very first decades of the 20th century. These diverse rigging systems reveal some developments to and influences on the tartane-type vessel, and they add complexity to our vision of a maritime cultural landscape in a coherent sailing space that includes the Gulf of Lion and Liguria.
Ships of the western Indian Ocean in Persian manuscript paintings
Authors: Ruyter Michael J. de
Published: August 2022

The preliminary review of 150 images of watercraft in Persian manuscript paintings from the 14th to the 19th centuries reveals the contextual environment of these much-maligned images of seafaring. Nautical researchers rarely cite Persian paintings, but availability of digital facsimiles of Persian manuscripts online has improved access to a large corpus of images allowing close exami­nation and comparisons. This study demonstrates the potential of the corpus of watercraft images in Persian manuscripts and shows how these paintings may be interpreted more as illustrations of seafaring culture rather than detailed depictions of nautical technology.
The “Big Ship” of Wismar: a well-preserved 12th-century cargo vessel from the harbour of Wismar
Authors: Ditta Massimiliano , Auer Jens
Published: August 2022

In December 2017, maritime archaeologists from the state department for archaeology in Mecklenburg Western Pomerania excavated, recovered, and documented a shipwreck in the seaport of Wismar. The wreck of a clinker-built cargo vessel was one of three medieval vessels found during the extension of the commercial port. With riveted outer planking and the presence of bitis, the wreck can be placed in the Nordic shipbuilding tradition. The results of the dendrochronological analysis show that the vessel was built from oak and pine sourced from western Sweden in the period AD 1184–1190. The construction shows striking similarities with a number of large 12th-century cargo vessels found in northern Germany and Scandinavia.
South and north: the linguistic mysteries of the buss
Authors: Thier Katrin
Published: August 2022

As the variety of names for ship types in the 12th and 13th century is greater than that of the archaeological evidence from the period, this is an attempt to contribute to the wider study of ship types by tracing the evidence provided by one particular word, which was in use both in northern and southern Europe at the time.
Different kinds of repairs and maintenance on a second century A.D. wreck: the Lyon Saint-Georges 4 barge
Authors: Guyon Marc , Meunier Laure
Published: August 2022

Thanks to the complete dismantling of the Lyon Saint-Georges 4 shipwreck prior to conservation work, interventions and repairs conducted after construction and before abandonment were noticed. This was a real opportunity for the acquisition of all kinds of archaeological data, ultimately revealing that only 25% of the data is available when the wreck cannot be dismantled.The recovery of this data is the result of a multidisciplinary approach. Conservators, wood specialists, metallurgists, textile specialists, archaeologists were able to describe, detail, and understand all the repairs and to rewrite the ship’s maintenance log. The complete dismantling also led to the recovery of a lot of waterproofing material, providing complementary data.
The shipwreck of the Jeanne-Elisabeth, a Swedish merchant ship lost off the French Mediterranean coast in 1755. Hull assembly: three different architectural traditions
Authors: Jaouen Marine , Poletto Andrea
Published: August 2022

The excavation of the Jeanne-Elisabeth began in 2008 and was led by archaeologists from the French Ministry of Culture. This Swedish brig of 200 tons sunk in November 1755 while sailing from Cadiz to Marseilles. The starboard hull is preserved for a length of 23 m, from the stem to the stern timbers, from the keel to the second deck. The assembly of the hull is a synthesis of the three traditions of shipbuilding in use in Wolgast, Germany, during the mid-18th century: Dutch, English and French. The Jeanne-Elisabeth is a great laboratory to study merchant ship construction as designed by a private shipyard in the mid-18th century.
A roman barge from the Kupa River at Kamensko, Croatia: Evidence of a Regional Shipbuilding Tradition of the Danube River Basin in Southeastern Europe
Authors: Boetto Giulia , Divić Anton , Zubčić Krunoslav
Published: August 2022

The Kamensko barge is a flat-bottomed fluvial vessel dated between the 1st century BC and the 3rd century AD. Its remains lie on the riverbed of the Kupa next to the town of Karlovac in Croatia. Constructed mostly from oak on the principles of bottom- based construction, it is 2 m wide and preserved to a length of 12 m. On its last journey it was transporting a cargo of several hundred bricks. Its interesting structural features suggest a kin- ship with other Roman-era shipwrecks from the Danube hydro-graphical basin.
Sustaining Higher Education Accreditation Through Institutional Affiliate Mentorship
Authors: Yalley Andrews A. , Dodoo Joana Eva
Published: August 2022

Higher education institutions particularly have been criticized for underperforming and lower quality of education. Subsequently, several regulatory bodies have been established in regulating and accrediting higher education institutions. Amongst them is the Ghana Tertiary Education Commission established in 1993 to fortify the quality of higher education in Ghana through its affiliation and mentorship initiative. Nevertheless, criticisms have been levied on its mentorship process and its tendency to create isomorphism. This chapter, using an integrative theoretical literature review methodology, developed and proposed a robust five-stage affiliate mentorship process model, namely initiation, modeling, coaching, scaffolding redefinition, and recommending strategies for enhancing its implementation as well as proposing areas for policy direction and theoretical exploration.
Efficiency of Accreditation Procedures in Slovenia
Authors: Faganel Armand
Published: August 2022

Quality assurance in higher education already has a long tradition. Internal and external quality assurance procedures guarantee the quality of education and research nowadays. It doesn't matter if the higher education institutions are private or public. They have to demonstrate the diligent handling of the financial resources they have acquired. Slovenian quality assurance agency (SQAA) is an autonomous and independent body that operates according to the standards and guidelines for quality assurance in the European higher education area. The Slovenian Court of Audit audited the quality assurance procedures SQAA in order to determine whether higher education study programs are of high quality and diverse. The audit discovered some inefficiencies of the evaluation and accreditation procedures, and in this chapter, the response and correction activities of the SQAA are being studied. Based on the findings, some recommendations for transparent work of quality assurance agencies are presented.
