Analyse des assignations d’une chercheure sereer par les enquêtés en France et au Sénégal
Authors: Ndour Rébecca
Published: October 2022

Résumé Cette contribution propose, en adoptant une approche réflexive, d’analyser comment ma position de chercheure et mon ethnicité ont été perçues par les enquêtés, lors des missions de terrain réalisées entre 2011 et 2015 dans le cadre de ma recherche doctorale qui portait sur les conditions d’émergence et de transmission intergénérationnelle de l’ethnicité sereer (Sénégal). L’enquête de terrain qui a démarré dans des associations dites « culturelles », à Paris et à Dakar, a été une occasion privilégiée pour observer l’ambiguïté de ma position et les modes de reconnaissance, à géométrie variable, de mon identification ethnique auprès de mes interlocuteurs. Alors que je me sentais, à titre personnel, appartenir au même groupe ethnique que les enquêtés et me présentais comme telle sur le terrain, je n’étais pas identifiée comme sereer par l’ensemble d’entre eux. À Paris, où je me sentais socialement très distante des enquêtés, j’étais néanmoins considérée comme une « membre exemplaire  ». À Dakar, où la distance sociale me semblait pourtant moindre, mon ethnicité sereer était sérieusement mise en doute. Mes déplacements entre Paris et Dakar soulignent ainsi les changements dans ma relation avec les enquêtés. Ces fluctuations, qui font littéralement de moi un objet d’analyse, révèlent la dimension potentiellement ambivalente et relative de l’ethnicité en même temps que sa fécondité en tant que concept sociologique.
Repenser la protection sociale par les communs sociaux : l’exemple des sociétés de secours mutuels du premier XIX e siècle en France
Authors: Audrain Sophie
Published: October 2022

Au début du XIX e  siècle se développent les sociétés de secours mutuels, en réaction à la poussée libérale, à l’industrialisation et au paupérisme grandissant. En mutualisant les risques sociaux, ces institutions de solidarité apportent des éléments de protection sociale et des droits sociaux à leurs sociétaires. Nous en proposons une analyse au prisme des communs sociaux, à partir d’une grille de lecture issue des récents apports théoriques sur les communs. Ce détour historique, rapprochant le champ des communs de celui de la protection sociale, apporte des éclairages pour repenser notre système de protection collective, face à l’urgence sociale, environnementale et démocratique.
VV-hemorphin-5 association to lipid bilayers and alterations of membrane bending rigidity
Authors: Valkova Iva , Todorov Petar , Vitkova Victoria
Published: October 2022

The morphinomimetic properties of hemorphins are intensively studied with regard to new peptide drug developments. In this respect, the investigation of mechanical properties and stability of lipid membranes provides a useful background for advancement in pharmacological applications of liposomes. Here we probed the effect of the endogenous heptapeptide VV-hemorphin-5 (valorphin) on the bending elasticity of biomimetic lipid membranes of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) by analysis of thermal shape fluctuations of nearly spherical giant unilamellar vesicles. In a wide concentration range covering valorphin concentrations applied in nociceptive screening in vivo, we report alterations of the bilayer bending rigidity in a concentration-dependent non-monotonic manner. We performed quantitative characterization of VV-hemorphin-5 association to POPC membranes by isothermal titration calorimetry in order to shed light on the partitioning of the amphiphilic hemorphin between the aqueous solution and membranes. The calorimetric results correlate with flicker spectroscopy findings and support the hypothesis about the strength of valorphin-membrane interaction related to the peptide bulk concentration. A higher strength of valorphin interaction with the bilayer corresponds to a more pronounced effect of the peptide on the membrane's mechanical properties. The presented study features the comprehensive analysis of membrane bending elasticity as a biomarker for physicochemical effects of peptides on lipid bilayers. The reported data on thermodynamic parameters of valorphin interactions with phosphatidylcholine bilayers and alterations of their mechanical properties is expected to be useful for applications of lipid membrane systems in pharmacology and biomedicine.
Finite-time stability of singular switched systems with a time-varying delay based on an event-triggered mechanism
Authors: Wang Yidan , Xiao Li , Guo Yanfeng
Published: October 2022

In this paper, the finite-time stability (FTS) of singular switched systems that have time-varying delays and perturbations is investigated. First, the concept of the FTS of time-varying delay singular switched systems is given, and a specific event-triggered mechanism is proposed. Then, a state feedback mechanism is proposed based on the event-triggered mechanism. Second, using the L-K function and state space decomposition, adequate criteria for the FTS of singular switched systems are found. Sufficient requirements are also presented for meeting the finite-time stable $ H_\infty $ performance index $ \gamma $.

Authors: Jayanthi N. , Santhakumari R. , Rajchakit Grienggrai , Boonsatit Nattakan , Jirawattanapanit Anuwat
Published: October 2022

In cluster synchronization (CS), the constituents (i.e., multiple agents) are grouped into a number of clusters in accordance with a function of nodes pertaining to a network structure. By designing an appropriate algorithm, the cluster can be manipulated to attain synchronization with respect to a certain value or an isolated node. Moreover, the synchronization values among various clusters vary. The main aim of this study is to investigate the asymptotic and CS problem of coupled delayed complex-valued neural network (CCVNN) models along with leakage delay in finite-time (FT). In this paper, we describe several sufficient conditions for asymptotic synchronization by utilizing the Lyapunov theory for differential systems and the Filippov regularization framework for the realization of finite-time synchronization of CCVNNs with leakage delay. We also propose sufficient conditions for CS of the system under scrutiny. A synchronization algorithm is developed to indicate the usefulness of the theoretical results in case studies.
Universal potential estimates for $ 1 < p\leq 2-\frac{1}{n} $
Authors: Nguyen Quoc-Hung , Phuc Nguyen Cong
Published: October 2022

We extend the so-called universal potential estimates of Kuusi-Mingione type (J. Funct. Anal. 262: 4205–4269, 2012) to the singular case $ 1 < p\leq 2-1/n $ for the quasilinear equation with measure data

   \begin{document}$ \begin{equation*} -\operatorname{div}(A(x,\nabla u)) = \mu \end{equation*} $\end{document}

in a bounded open subset $ \Omega $ of $ \mathbb{R}^n $, $ n\geq 2 $, with a finite signed measure $ \mu $ in $ \Omega $. The operator $ \operatorname{div}(A(x, \nabla u)) $ is modeled after the $ p $-Laplacian $ \Delta_p u: = {\rm div}\, (|\nabla u|^{p-2}\nabla u) $, where the nonlinearity $ A(x, \xi) $ ($ x, \xi \in \mathbb{R}^n $) is assumed to satisfy natural growth and monotonicity conditions of order $ p $, as well as certain additional regularity conditions in the $ x $-variable.
The Role of Library Digitization in Access and Preservation of Library Resources
Authors: Chigbundu Michael Chinweike
Published: October 2022

Digitization implies conversion of a paper document to a digital document. The main reasons for library digitization are to enhance access and preservation of library resources. Despite the benefits of library digitization, it is disheartening to know that while libraries in developed countries are putting in efforts digitizing their resources, little effort is being put by libraries in developing countries to digitize their resources. Hence, this chapter attempts to create awareness of the importance of library digitization in the preservation and enhancement of access of library resources. In addition to discussing the roles of library digitization in preservation and enhancement of access of library resources, the chapter also discussed some digitization tools, some misconceptions of library digitization, stages of library digitization, and some challenges of library digitization. Some recommendations were also given in the chapter.
Impact of SHRM on Employee Commitment in Tertiary Educational Institutions in Ghana
Authors: Kumah Peace
Published: October 2022

The impact of strategic human resource management on employee commitment in educational institutions is yet to be properly documented. This study investigated the impact of SHRM (strategic fit, role-position fit, intra-functional fit, and cross-functional fit) on employee commitment. Employing a survey research approach, data were collected from 314 employees in tertiary educational institutions in a developing country. A conceptual model was developed and hypotheses were proposed. Using partial least squares structural equation modeling technique, the proposed model explained 40% of employees' affective commitment, about 3% of employees' continuance commitment, and about 7% of employees' normative commitment. The cross-functional fit had the most significant effect on affective commitment. The result also revealed that not all SHRM practices could produce a positive significant effect on employee commitment. This study proposed a conceptual model and contributed to the formulation of HR policy and guidelines in tertiary institutions for improving employee commitment.
Multimodal Translation and Communication of Cultural Terms With Chinese Characteristics
Authors: Wan Jia
Published: October 2022

In recent years, as the digital technology develops by leaps and bounds and the intercultural communication deepens further, Chinese culture has been presented in multimodal texts such as visual texts, audiovisual texts, and hypertexts. The term translation in multimodal texts is different from that in single-modal texts in many ways, but translators often overlook other modalities than verbal text when translating terms. At first, this study discussed the multimodal interpretations of Chinese cultural terminology. Then, Dunhuang cultural terms and their corresponding translations in different multimodal texts were collected. By analyzing the existing term translations, it was found that translators often translate the literal meaning of the terms and ignore other modalities such as images, so the acceptability of the terms is not high. Also, there are no established principles and strategies to guide its translation. Therefore, this study explored any practicable principles or strategies that could guide the cultural term translation in multimodal texts.
On the Implied Wholeness Significance of International Financial Cooperatives and Credit Unions
Authors: Vemić Milan B.
Published: October 2022

The purpose of this paper is to analyze pre-COVID-19 performance indicators of international financial cooperatives and credit unions. By assuming a wholeness approach to cooperative development, new potentialities are suggested without jeopardizing the initial concept of non-financial cooperative entities. Researched is their internationalization and export endeavors based on data collected by the European Association of Cooperative Banks and the World Council of Credit Unions. The author draws conclusions on interconnectedness among financial cooperatives and credit unions with traditional cooperatives. This study suggests that credit unions seem to be more widely represented than international financial cooperatives and that development potential exists in both of them individually and especially in their holistic interconnectedness. Finally, findings of this research also reveal that classic cooperatives could evolve into players that are more powerful by developing their financial and market potential through cooperation with international financial cooperatives and credit unions.
Knowledge Management Capability, Organizational Resilience, and the Growth of SMEs
Authors: Zheng Shuli , Shen Yuyan , Liu Luming
Published: October 2022

How small and medium-sized enterprises (SMEs) survive and grow is a matter of great concern not just to enterprises but also to governments. Although past studies have mainly focused on the driving forces of corporate growth, they have yet to investigate how SMEs can build resilience and then achieve growth through their own knowledge management within challenging environments. Therefore, this paper empirically examines the internal links among knowledge management capabilities (KMC), organizational resilience (ORE), and the growth of SMEs under the influence of environmental munificence (EM). After analyzing the sample data from Chinese SMEs, results show that KMC actively promotes the growth of SMEs from both size expansion and qualitative optimization and that it can significantly positively affect the construction of ORE. In turn, ORE plays an intermediary role in the relationship between KMC and qualitative optimization. In addition, EM has negative moderating effects both on the relationship between KMC and the quality optimization of SMEs and that between KMC and ORE.

Authors: Seethur Rashmi , Yellampalli Siva , Shreedhar H. K.
Published: October 2022

In this paper, an ultra-wide band (UWB) low noise amplifier (LNA) is implemented by using 90nm RF CMOS technology. The designed LNA achieves high flat band gain (S21) and low noise figure (NF) in the frequency of interest. The proposed LNA operates in the frequency range of 3GHz to 8GHz. In this work, wide band matching is achieved by designing common gate configuration at the input stage. The current reuse and noise cancellation techniques are introduced to improve flat band gain and minimize both noise figure and power consumption. The noise figure is improved by cancelling dominant noise sources with additional hardware. The proposed LNA attains flat band gain of 26.5dB and input matching less than -12dB for entire UWB band. This work achieves noise figure of 2.1dB to 2.59dB in frequency band of interest. Additionally, power consumption of the circuit is 20mW at 1.8V supply voltage.
Forecasting Telecommunication Network States on the Basis of Log Patterns Analysis and Knowledge Graphs Modeling
Authors: Krinkin Kirill , Vodyaho Alexander Ivanovich , Kulikov Igor , Zhukova Nataly
Published: October 2022

The article proposes a state forecasting method for telecommunications networks (TN) that is based on the analysis of behavioral models observed on users' network devices. The method applies user behavior that makes it possible to forecast with more accuracy both the network parameters and the load at various back-ends. Suggested forecasts facilitate implementing reasonable reconfiguration of the TN. The new method proposed as a further development of TN states the forecasting method presented by the authors before. In this new version, forecasting algorithm users' behavioral models are involved. The models refer to a class of time diagrams of device transitions between different states. The novelty of the proposed method is that resulting TN models enable forecasting device state transitions represented in a device state diagram in the form of knowledge graph, in particular changes in loads of different back-ends. The provided case study for a subgroup of network devices demonstrated how their states can be forecasted using behavioral models obtained from log files.

Authors: Punchoojit Lumpapun
Published: October 2022

A substantial amount of research has been conducted to investigate the effects of physical and cognitive changes on smartphone task performance. Prior research examined the effects of age difference and smartphone visual search tasks. The results confirmed the effects of age on task performance. Several surprising findings emerged during the processing of the data. Aside from task performance, differences in demographic characteristics and smartphone usage habits were found between elderly and other age groups. After reviewing literature, the authors found that there has not been any research on how demographic characteristics or usage behaviors may be related to smartphone task performance. The objectives of this present study are to examine how demographic characteristics correlated to smartphone task performance and to compare general and senior users. The results showed differences between general and senior users in term of demographic characteristics and smartphone usage behaviors. The analysis found that both demographic factors and usage behavior correlated with task performance.
Bug Triage Automation Approaches
Authors: Fanoos Madonna , Hamdy Abeer , Nagaty Khaled A.
Published: October 2022

Bug triage is an essential task in the software maintenance phase. It is the process of assigning a developer (fixer) to a bug report. A personnel (triager) has to analyze the developers' profiles and bug reports for the purpose of making a suitable assignment. Manual bug triage consumes time and effort, so automating this process is a necessity. The previous research studies addressed the triage problem as an information retrieval problem, where the new bug report is the query. Other researchers tackled this problem as a classification problem and utilized traditional machine learning or deep learning techniques. A handful of research studies handled this problem as an optimization problem and utilized optimization algorithms such as Hungarian. This paper briefs and analyzes the previous bug triage approaches in addition to conducting an empirical comparison among five of the previous approaches.

Authors: Wang Jiaji
Published: October 2022

In 2019, the outbreak of a new coronavirus spread rapidly around the world. The use of medical image-assisted diagnosis for suspected patients can provide a more accurate and rapid picture of the disease. The earlier the diagnosis is made and the earlier the patient is treated, the lower the likelihood of virus transmission. This paper reviews current research advances in the processing of lung CT images in combination with promising deep learning, including image segmentation, recognition, and classification, and provides a comparison in a tabular format, hoping to provide inspiration for their future development.
Group Work Using Active Learning
Authors: Sugawara Ryo , Okuhara Shun
Published: October 2022

An active learning group work course at “A” university in Japan is characterized by two-way interactions between students as well as between teachers and students. The spread of COVID-19 prompted a shift from in-person lessons to online synchronous lessons in 2020 and 2021. This mixed methods study analyzes data from a combined structured and open-ended questionnaire completed by 5,268 students. The results showed that online lessons were significantly more highly evaluated than face-to-face lessons in terms of enhancing students' understanding of student life, sense of belonging, expressing one's opinions and listening to those of others, and self-regulation of attendance and gaining an in-depth understanding of the course material. However, face-to-face lessons were preferred for small class sizes, interactions with students who have different ideas, and group learning activities. Open-ended responses indicated that conducting online classes via Zoom improved students' perceptions of group learning and interaction in this setting.
Elementary Students' Mathematics Curiosity
Authors: Kundu Arnab , Bej Tripti
Published: October 2022

This investigation aimed to determine the best pedagogical approach to sustain mathematics curiosity among elementary students. It reports a comparative pedagogy of three popular modes of course delivery— face-to-face, online, and blended— in terms of their potential to excite students' curiosity. A design study was conducted in a government-run Indian elementary school among 200 fifth-grade students randomly divided into three groups taught in three different modes. Students' levels of curiosity were tested before and after the experimentation. The pre- and post-test data were analyzed quantitatively using one-way ANOVA. Findings revealed that students who taught in the blended mode exhibited the highest level of curiosity compared to the rest of the two modes. The difference in curiosity level between the blended and the face-to-face mode was intense while the difference between the blended and the online mode was weak. Therefrom, the authors conclude that the blended mode could be the most effective pedagogical approach for elementary mathematics to keep students curious.

Update on Adjuvant Treatment in Resectable Non-Small Cell Lung Cancer and Potential Biomarkers Predicting Postoperative Relapse
Authors: Lim Jeong Uk
Published: October 2022

A significant proportion of patients with non-small cell lung cancer (NSCLC) is diagnosed in the early and resectable stage. Despite the use of platinum-based adjuvant chemotherapy, there was only a marginal increase in overall survival and a 15% decrease in relapse. With the advents of immunotherapy and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), the landscape of adjuvant treatment in completely resectable NSCLC is changing. Postoperative radiotherapy can be beneficial to patients who underwent surgical resection in certain clinical settings. In addition, new biomarkers that predict efficacy of EGFR TKI and immunotherapy as adjuvant treatment are also necessary. In this review, recent updates in adjuvant treatment in resectable NSCLC were briefly explained.
Sampling and laboratory protocols to study the effects of water-level management on the littoral invertebrate fauna in deep and large temperate lakes

Published: October 2022

An integrated multidisciplinary protocol on monitoring, sampling, and laboratory procedures was developed and proposed as part of the Project "Parks Verbano Ticino" in the framework of the INTERREG V-A Italy-Switzerland 2014-2020 Cooperation Program. The project's overall goal is to evaluate the effects of water-level management (hydro-morphological stress) on both macro- and meio-fauna along the shores of Lake Maggiore, a large and deep temperate lake in northwest Italy. Because of their importance in the aquatic food web, determining how this stress affects macro- and meio-faunal assemblages is difficult. The protocol developed thus includes the evaluation of hydro-morphological impacts via the Lake Habitat Survey method, which entails monitoring of human-induced impacts and related infrastructures, followed by an in-depth evaluation of the ecological health of lake habitats via chemical analyses. The protocol then describes the sampling methods for shallow lake waters (i.e., <1.5 m depths) of deep lakes, but it also provides guidance on the best time to sample, how to select sampling sites, and how to allocate sample replicates along transects. A detailed step-by-step laboratory procedure for sample treatment was provided in order to assess the structure of macro- and meio-fauna assemblages, as well as morpho-functional traits (e.g., body shape and size, biomass estimate) in response to water-level management. For the first time, a set of morphological and functional characteristics of macro- and meio-faunal taxa are proposed for comparison. The protocol for standardized trait measurement is intended to be widely used. We also proposed chironomid species-specific length-mass regression models for biomass estimation, which is important for determining growth rate and secondary production of these taxa in temperate zone lakes. Length-mass equations could shed light on the role of specific species in the flow of energy through aquatic ecosystems. The proposed protocol was evaluated by team members to ensure common utility, accuracy, and repeatability of the procedures in order for researchers and stakeholders involved in water management of lakes with similar physical characteristics to use it. The protocol, which has been adapted or simply developed to meet the needs of the Italian context, could be successfully applied to other Alpine and Mediterranean temperate, deep lakes, reservoirs, and other glacial, volcanic, and morainic lakes, as well as to a broader European context.

Authors: Manickam Navakumar , Gopalan Kannan , Nisha Ann Shaji , Kulandaivel Anbu Lenin
Published: October 2022

Plexiform schwannoma (PS) is a rare benign encapsulated peripheral nerve sheath tumor characterized by a plexiform pattern of intraneural growth often with a multinodular appearance. It usually presents as a solitary mass with a strong predilection for young adults between 20 and 50 years. Despite its common presentation in the head and neck region, involvement of the lip is extremely rare. Multiple cutaneous PSs are commonly associated with Neurofibromatosis type 2 or Schwannomatosis. To date, only a few cases of PS involving the lip have been reported. Here in we report another unusual case of PS involving the angle of mouth which was removed completely by surgical excision without any recurrence seen at 1-year post-surgery.

Authors: Rani Seema , Chitkara Anubhuti , Sharma Prafulla K. , Sinha Saket , Sharma Preeti
Published: October 2022

Objective:

Women with diffuse hair loss need to be screened for possible causes or factors responsible for increased hair shedding and also to exclude factors that can increase hair shedding and aggravate the disease.

Material and Methods:

A prospective cross-sectional study of 40 cases (18–45years) of diffuse hair loss and 40 healthy females were included. The diagnosis was based on the detailed history, clinical examination to rule out pattern hair loss, and hair pull test. Complete hemogram, serum ferritin, vitamin D, and thyroid function tests (T3, T4, thyroid-stimulating hormone [TSH]) along with all routine investigations were determined for each participant. A diet history of vegetarians and non-vegetarians was also taken.

Results:

On screening, serum ferritin in cases ranged from 3.92 to 104 ng/mL with a mean of 22.36±23.10 ng/mL and that in controls ranged from 5.5 to115 ng/mL with a mean of 29.97±45.72 ng/mL. The serum ferritin level in cases was lower, at a cut-off value of 10 ng/mL, which is statistically significant (p= 0.027). For those with serum ferritin level >10 ng/mL, the mean concentration of hemoglobin was 11.65 ± 0.79 gm%, whereas for the <10 ng/mL serum ferritin level, the mean concentration of hemoglobin was 11 ± 1.1 gm% with a significant statistical difference (p= 0.027). The serum level of vitamin D in cases ranged from 8 to 57.4 IU/dL with a mean of 20.24±11.98 IU/dL while that in controls ranged from 11.1 to 42.6 IU/dL with a mean of 22.42±9.29 IU/dL, which was statistically significant difference (p= 0.003). We found no association of thyroid dysfunction with diffuse hair loss. On dietary evaluation, significant statistical association among vegetarians (67.5% cases and 40% controls) and non-vegetarians (32.5% cases and 60% controls) was observed (p= 0.024); however, we could not find any statistical significant association of diet with ferritin and vitamin D.

Conclusion:

Low ferritin and vitamin D may contribute to diffuse hair loss.

Published: October 2022

The Žune Ba-F epithermal deposit is situated in the Ljubija ore field (NW Bosnia and Herzegovina), within Upper Palaeozoic dolostone. A typical ESE-WNW Variscan vergency fault zone separates the dolostone from Lower Triassic schists and sandstones. External and internal pseudo-bedding, with massive, homogenous structure and partial limonitization characterizes the dolostone. Its geochemical composition exhibits low SiO2 (1.33 – 2.06 mass. %), Al2O3 (0.27 –0.38 mass. %), BaO (0.02 – 0.83 mass. %), ƩREE (5.7 – 9.4 ppm), Sr (61.7 – 120.4 ppm), Sm (0.3 – 2.2 ppm) and Eu (0.1 – 0.6 ppm), while having high CaO (30.24 – 32.38 mass. %), MgO (16.47 – 17.35 mass. %) and LOI (44.6 – 45.58 mass. %). The dolostone-mineralization contact zone consists of metasomatically recrystallised host dolostone with quartz and pyrite, where the presence of accessory tremolite, magnesiochloritoid and pyknite indicates peak formation conditions in the pre-mineralization phase with temperatures above 300°C. Two ore types are described: (i) Ba-F vein-type mineralization composed of barite – fluorite ± quartz, and (ii) hydrothermal breccia composed of coarse-grained fluorite and barite, surrounding fragments of dolostone, and occupying ≈20 % of the deposit. Mineralized samples show slightly elevated SiO2 (2.20 – 5.53 mass. %) and Al2O3 (0.24 – 0.74 mass. %), low MgO (below 0.02 mass. %) and LOI (0.3 – 3.1 %), with high BaO (up to 50.74 mass. %), CaO (up to 66.03 mass. %), ƩREE (20 – 166 ppm), Sr (exceeding 1 mass. %), Sm (up to 118 ppm) and Eu (up to 44 ppm). Elevated Sr can be correlated to other barite epigenetic hydrothermal deposits in the Dinarides, interpreted as BaSr substitution in the barite crystal lattice. Fluorite-rich samples are characterized by Y (0.6 –49.2 ppm) and HREE enrichment, accompanied by depletion of LREE. The Ba-F deposit Žune, having variable REE concentration and a negative cerium and ytterbium anomaly corresponds geochemically to world-class fluorite deposits associated with carbonate sedimentary rocks.

Ships and associated anthropogenic activities release a number of contaminant elements into the marine environment which can be particularly concentrated in restricted circulatory environments including Bays and marinas. One such locality is a Punat Bay, situated at the southern coastline of the island of Krk (west Croatia), which is the largest Croatian marina. The aim of this study was to examine depth profiles of sulfur (S), phosporous (P), iron (Fe), and trace elements (As, Ba, Be, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sn, Sr, Ti, U, V, Y, and Zn) in six sediment cores (down to 20-30 cm), and from mussels and fish from Punat Bay, by determining their levels with ICP-OES. Data analysis showed that the majority of variables were elevated in a sediment core located closest a port of the marina. Minimum to maximum S, P, and Fe levels in sediments were as follows: 0.4-2.4%, 0.04-320 mg/kg, and 0.2-2.3%, respectively. Correlations among S, P, Fe, and various trace elements were mostly positive (p<0.05). Trace elements were not increased in mussels and fish. This paper shows that the Punat marina has only a limited impact on the environmental status. Several potentially toxic trace elemens (Pb, Cu, etc.) were found to be elevated in a sediment core located closest to the marina.
Moving beyond the ad hoc responses in flood management to a localization approach in Ghana
Authors: Anab Chrysogonus , Abazaami Joseph , Achanso Sulemana Adam
Published: October 2022

Flooding has become one form of disaster that has become both a national and global concern. In Ghana, flooding has become a yearly ritual, displacing many community members, destroying farmlands, and cutting off communities. The state institution mandated to coordinate and manage disasters is the National Disaster Management Organisation (NADMO). However, NADMO is always overwhelmed with the level of humanitarian assistance required by flood victims annually due to limited resources. Floods management in Ghana is largely reactionary and short-term, hence the need for long-term planning. The researchers therefore used both secondary and primary data to investigate the drivers and gaps in the existing flood management approaches. The findings showed that inadequate funding, non-enforcement of settlement and farming laws; unhealthy environmental practices and low investments in flood containment infrastructure were the drivers of the perennial floods in Ghana. The major gap identified was the over reliance on central government and development partners to finance flood preparedness, response and recovery interventions. These funding sources have always been inadequate and irregular. The study concluded with a recommendation to NADMO and other state agencies to adopt a long-term, holistic and locally driven approach to flood management in Ghana.

MEB değerler sınıflandırmasında yer alan değerler, Ward bağlantı (en küçük varyans) yöntemi kullanılarak; muhafazakâr-geleneksel, ulusal-milli, öze dönük-kişisel, sosyal-toplumsal, bilimsel-yenilikçi değerler olmak üzere incelenen beş küme içerisinde yer alan “sosyal-toplumsal ve bilimsel-yenilikçi” değerlere göre incelenmiştir. İncelenen metinlerde geçen değerler 12 başlık altında sınıflandırılarak, tablo haline getirilmiştir. Çalışmada, 141 Kıbrıs masalında ve 70 Elazığ masalında yer alan “sosyal-toplumsal ve bilimsel-yenilikçi” değerler tespit edilmiştir. Kıbrıs masallarında sosyal-toplumsal değerlere 129, bilimsel-yenilikçi değerlere 36 kez yer verilirken Elazığ masallarında sosyal-toplumsal değerlere 83, bilimsel-yenilikçi değerlere 24 kez yer verildiği görülmüştür.

STUDY AND CHARACTERIZATION OF OLD KINGDOM PERIOD POTSHERDS FROM ABUSIR EXCAVATION. A CASE STUDY
Authors: MOHAMED HAMDY MOHAMED
Published: October 2022

The current work describes the different methods used to investigate various potsherds. The potsherds were discovered at the Abusir archaeological site, dating back to the Old Kingdom period. This research aims to study the chemical and mineralogical composition of the potsherds and salt crystallization. For this purpose, the analytical study was carried out using different techniques such as a digital and polarizing microscopy, scanning electron microscopy coupled with X-ray energy dispersion (SEM/EDX), and X-ray diffraction. Microscopic examination shows that potsherds suffer, from different deterioration aspects, such as salt crystallization, accumulation of dust, and black spots. The results of the polarized microscope proved that sand, grog powder, and calcite were used as additive materials to improve clay's properties. The EDX and XRD methods used in the current work provide an essential chemical view of the structure of the samples. The results of EDX confirmed the presence of a high percentage of chloride salts, iron, and aluminium oxides. XRD results revealed that the firing temperature of the potsherds is high, around 850-950 oC. Therefore, the hardness of these sherds is high. There is little doubt that this will aid in conserving this valuable pottery.

In the study, the effects of selenium on intestinal tissue morphology, antioxidant-related genes, and intestinal flora of grass carp (Ctenopharyngodon idella) were studied. For this purpose, 180 healthy grass carps (20.0±2.0 g) were randomly divided into three groups with three replicates each: the corresponding amount of anhydrous sodium selenite was added to make experimental water solutions of different concentrations, including 0 μg/L Se4+ (control group), 200 μg/L Se4+ group and 300 μg/L Se4+ group. The experiment was carried out for 42 days. The obtained results showed that: at the end of the experiment, the 200 μg/L Se4+ adaptation can have beneficial effects on the intestinal villi height and goblet cells. The CuZnSOD and CAT genes mRNA levels of grass carp intestine were strongly upregulated in the 200ug/L Se4+ group. 200ug/L selenium could increase the expression level of the Hsp70 gene in the intestinal tract of grass carp after 42 days of adaptation. At the genus level, the most abundant sequence in the gut of Se-treated grass carp was Pseudomonas, while Aeromon, Flavobacterium, and Defluviimonas were more abundant in the control group. In conclusion, this study demonstrates that 200ug/L Se4+ selenium adaptation can positively affect gut morphology and antioxidant responses and can alter the gut microbiota structure of grass carp. The results will provide a theoretical basis for further research on the effect of selenium on aquatic animals.
Hırpalanmış Kadın Sendromu: Çalışan Kadınlar Açısından Bir İnceleme
Authors: ECE Süreyya
Published: October 2022

Aile içinde veya yakın bir partneri tarafından hırpalanan

kadınlar maruz kaldıkları kötü muamele sonucunda

sendrom yaşayabilmektedir. Bu sendrom hırpalanmış

kadın sendromu olarak ifade edilmiştir. Hırpalanmış

kadın sendromu kadınların günlük yaşamlarını olumsuz

yönde etkilemekte, bir işyerinde çalışan kadınlarda ise iş

yaşamında da olumsuz sonuçlar doğurabilmektedir. Bir

kadın çalışanın işine odaklanamaması, performansının

düşmesi, potansiyelini tam olarak ortaya çıkartamaması,

işyerinden sık sık izin alması gibi durumların yaşanması

hırpalanmış kadın sendromu sonucu

gerçekleşebilmektedir. Bu açıdan bakıldığında kadına

yönelik şiddetin iş yaşamını da etkileyen bir sorun

olduğu anlaşılmaktadır. Bu durum özellikle toplumsal

cinsiyete dayalı rol dağılımının olduğu toplumlarda

kadınların çalışma yaşamında başarısız olacağı

argümanına kanıt olarak sunulabilmektedir. Oysaki

kadın çalışanın işyerindeki performansının maruz

kaldığı şiddet kaynaklı olduğu ortaya konulduğu

takdirde bu tür yanlış yargıların da önüne geçmek

mümkün olabilecektir.

Bu çalışmada sosyolojik ve hukuki temellere dayanan

hırpalanmış kadın sendromu iş yaşamı açısından ele

alınmıştır. Çalışmanın amacı hırpalanmış kadın

sendromuna ilişkin kavramsal bir çerçeve çizerek iş

yaşamındaki yansımalarına dair bilgi vermektir.

Çalışmada ayrıca hırpalanan kadın çalışanlar için kurum

yöneticilerinin alabileceği tedbirlere yönelik bazı

önerilerde bulunulmuştur.

Introduction: To explore the relationship between ethnic origin and mode of feeding with early neonatal jaundice, we examined maternal and neonatal risk factors for hyperbilirubinaemia in a multi-ethnic Asian cohort of healthy term newborns. Materials and Methods: This is an observational cohort study in a maternity ward serving a multi-ethnic cosmopolitan community. The relationship between hyperbilirubinaemia (bilirubin 150 mmol/L before 48 hours to 72 hours after birth), ethnic origin, weight loss after birth, need for phototherapy, and other factors were examined. Bivariate comparisons and binary logistic regression were used to investigate the relationship between hyperbilirubinaemia/phototherapy with maternal and neonatal risk factors. Results: A consecutive group of 1034 neonates (56% Chinese, 24% Indian subcontinent, 9% Malay) with birth weights 2500 g was investigated. Overall factors that contributed signifi- cantly to hyperbilirubinaemia/phototherapy were gestational age, Chinese ethnic origin, weight loss of 7%, vaginal delivery, glucose-6-phosphate-dehydrogenase (G6PD) deficiency, breastfeeding and ABO incompatibility. Chinese neonates who were totally breastfed had a higher risk for jaundice [adjusted odds ratio (OR) = 1.64; 95% confidence intervals (CI), 1.11- 2.44; P <0.014], and phototherapy (adjusted OR = 2.75; 95% CI 1.77-4.27; P <0.001) compared to those supplemented with, or totally formula fed. In contrast, the risk of jaundice for non- Chinese infants did not differ according to the mode of feed. Although weight loss as a whole increased the risk for jaundice (adjusted OR = 1.43; 95%CI, 1.03-1.99; P = 0.031), jaundice in Chinese neonates was not due to ineffective breastfeeding because both Chinese and non-Chinese breastfed infants lost similar weights. Conclusions: Chinese ethnic origin was an independent risk factor for hyperbilirubinaemia and phototherapy. Breastfeeding was not a risk factor for hyperbilirubinaemia/phototherapy in non-Chinese Asian infants. Key words: Breastfeeding, Ethnicity, Neonatal jaundice, Phototherapy
3rd College of Surgeons Lecture — Bringing up Surgeons
Authors: Ong Siew Chey
Published: October 2022

The talk traces briefly the development and changes of surgical training in the English- speaking world in the early days and the trials and tribulations of surgical training in Singapore a few decades ago. The factors that brought about the surge of American surgery from late 19th century to the first half of the 20th century are discussed. Structured surgical training leading to the exit point was introduced by William Halsted of Johns Hopkins Hospital around 1892, a system that was later adopted by all other medical disciplines and by all other hospitals in the US. It is considered to be the prime mover of the rapid progress of American medicine. Training surgeons to only the entry point while leaving the competence of trainees to chance, used to be common in the British surgical world. The trend now favours surgical training to the exit point. It is also the system being adopted in Singapore. Increasing demands of high standard of patient care and public accountability no longer allow us to be casual and permissive mentors of future generations of surgeons. Proper surgical upbringing requires a good structured programme that itself needs to be accredited and periodically reviewed. It also requires that discipline be observed on the part of trainees. Knowledge and skills are within the capability of our mentors to impart, but inculcation of good attitude and ethics in trainees is a harder goal to achieve. Key words: Attitude, Discipline, Training
