Clinical data suggest that cardiosphere-derived cells (CDCs) could modify post-infarction scar and ventricular remodeling and reduce the incidence of ventricular tachycardia (VT). This paper assesses the effect of CDCs on VT substrate in a pig model of postinfarction monomorphic VT. We studied the effect of CDCs on the electrophysiological properties and histological structure of dense scar and heterogeneous tissue (HT). Optical mapping and histological evaluation were performed 16 weeks after the induction of a myocardial infarction by transient occlusion of the left anterior descending (LAD) artery in 21 pigs. Four weeks after LAD occlusion, pigs were randomized to receive intracoronary plus trans-myocardial CDCs (IC+TM group, n: 10) or to a control group. Optical mapping (OM) showed an action potential duration (APD) gradient between HT and normal tissue in both groups. CDCs increased conduction velocity (53 ± 5 vs. 45 ± 6 cm/s, p < 0.01), prolonged APD (280 ± 30 ms vs. 220 ± 40 ms, p < 0.01) and decreased APD dispersion in the HT. During OM, a VT was induced in one and seven of the IC+TM and control hearts (p = 0.03), respectively; five of these VTs had their critical isthmus located in intra-scar HT found adjacent to the coronary arteries. Histological evaluation of HT revealed less fibrosis (p < 0.01), lower density of myofibroblasts (p = 0.001), and higher density of connexin-43 in the IC+TM group. Scar and left ventricular volumes did not show differences between groups. Allogeneic CDCs early after myocardial infarction can modify the structure and electrophysiology of post-infarction scar. These findings pave the way for novel therapeutic properties of CDCs.

Published: December 2022

κ-carrageenases are members of the glycoside hydrolase family 16 (GH16) that hydrolyze sulfated galactans in red algae, known as κ-carrageenans. In this study, a novel κ-carrageenase gene from the marine bacterium Rhodopirellula sallentina SM41 (RsCgk) was discovered via the genome mining approach. There are currently no reports on κ-carrageenase from the Rhodopirellula genus, and RsCgk shares a low identity (less than 65%) with κ- carrageenase from other genera. The RsCgk was heterologously overexpressed in Escherichia coli BL21 and characterized for its enzymatic properties. RsCgk exhibited maximum activity at pH 7.0 and 40 °C, and 50% of its initial activity was retained after incubating at 30 °C for 2 h. More than 70% of its activity was maintained after incubation at pH 6.0–8.0 and 4 °C for 24 h. As a marine derived enzyme, RsCgk showed excellent salt tolerance, retaining full activity in 1.2 M NaCl, and the addition of NaCl greatly enhanced its thermal stability. Mass spectrometry analysis of the RsCgk hydrolysis products revealed that the enzyme had high degradation specificity and mainly produced κ-carrageenan disaccharide. Comparative molecular dynamics simulations revealed that the conformational changes of tunnel-forming loops under salt environments may cause the deactivation or stabilization of RsCgk. Our results demonstrated that RsCgk could be utilized as a potential tool enzyme for efficient production of κ-carrageenan oligosaccharides under high salt conditions.

Published: December 2022

With respect to the potential natural resources in the marine environment, marine macroalgae or seaweeds are recognized to have health impacts. Two marine algae that are found in the Red Sea, Codium tomentosum (Green algae) and Actinotrichia fragilis (Red algae), were collected. Antibacterial and antioxidant activities of aqueous extracts of these algae were evaluated in vitro. Polyphenols from the extracts were determined using HPLC. Fillet fish was fortified with these algal extracts in an attempt to improve its nutritional value, and sensory evaluation was performed. The antibacterial effect of C. tomentosum extract was found to be superior to that of A. fragilis extract. Total phenolic contents of C. tomentosum and A. fragilis aqueous extract were 32.28 ± 1.63 mg/g and 19.96 ± 1.28 mg/g, respectively, while total flavonoid contents were 4.54 ± 1.48 mg/g and 3.86 ± 1.02 mg/g, respectively. Extract of C. tomentosum demonstrates the highest antioxidant activity, with an IC50 value of 75.32 ± 0.07 μg/mL. The IC50 of L-ascorbic acid as a positive control was 22.71 ± 0.03 μg/mL. The IC50 values for inhibiting proliferation on normal PBMC cells were 33.7 ± 1.02 µg/mL and 51.0 ± 1.14 µg/mL for C. tomentosum and A. fragilis, respectively. The results indicated that both algal aqueous extracts were safe, with low toxicity to normal cells. Interestingly, fillet fish fortified with C. tomentosum extract demonstrated the greatest overall acceptance score. These findings highlight the potential of these seaweed species for cultivation as a sustainable and safe source of therapeutic compounds for treating human and fish diseases, as well as effective food supplements and preservatives instead of chemical ones after performing in vivo assays.

Published: December 2022

The pharmacy education and its educators have to expose the student pharmacists to a plethora of activities regarding health disparities. It is essential for student pharmacists to be introduced to the key elements that comprise the Social Determinants of Health (SDOH) during their didactic curriculum. However, while there have been efforts made in the United States to incorporate the SDOH in the pharmacy curricula, there is limited research on student pharmacists’ perspectives of how content in the didactic curriculum prepared them to provide patient care. A quantitative approach was used for this study. For the Class of 2023, activities were added to a skills-based course series and a professional development course series to introduce, apply, and illustrate how SDOH can impact pharmacist-provided care and patient health experiences. As part of the College’s assessment plan, a survey is sent to the third-year student pharmacists in January prior to beginning Advanced Pharmacy Practice Experiences (APPEs). The online survey consists of 24 Likert Scale questions with five choices ranging from Strongly Agree to Strongly Disagree and not applicable. Four of the 24 questions pertained to health disparities and SDOH and were evaluated in this study. The responses were analyzed using SPSS for Windows, version 25.0 (IBM Corporation, Armonk, NY, USA). Descriptive statistics were calculated for all variables. Chi-square tests were used for all nominal data and Mann–Whitney test was used for all nonparametric numeric data. A total of 530 student pharmacists completed the survey. The mean age was 26 years and majority of the respondents identified as female (64%). More students strongly agreed that they had the ability to identify and address SDOH to improve access to or the delivery of healthcare in the class of 2023 (51.4%) compared to the class of 2022 (37.8%) and class of 2021 (35.8%). In addition, the mean survey score for the question between the class of 2023 improved significantly compared to the class of 2022 (p = 0.015) and 2021 (p = 0.004). Overall, this study suggests that longitudinal activities involving SDOH can improve student pharmacists’ assessment of their abilities to interact with and care for a diverse patient population. The results suggest that the curriculum activities implemented to address a plethora of patients improve student assessment of their abilities to identify and incorporate SDOH in providing patient-centered care.
Religions, Women and Discourse of Modernity in Colonial South India
Authors: Doss M. Christhu
Published: December 2022

Colonial education and missionary discourse of modernity intensified struggles for continuity and change among the followers of Hinduism and Christianity in nineteenth century India. While missionary modernity was characterised by an emphasis on sociocultural changes among the marginalized women through Christian norms of decency, orthodox Hindus used traditional cultural practices to confront missionary modernization endeavours. This article posits that the discourse of missionary modernity needs to be understood through the principles of Western secular modernity that impelled missionaries to employ decent clothing as a symbol of Christian femininity. It argues that missionary modernity not only emboldened the marginalized women to challenge their ascribed sociocultural standing but also solidified communitarian consciousness among the followers of Hinduism and Christianity substantially. Even though Travancore state defended the entrenched customary practices, including women’s attire patterns, with all its potency through authoritative proclamations, it could not dissuade missionaries from converting the marginalized women to missionary modernity.
A Symbols Based BCI Paradigm for Intelligent Home Control Using P300 Event-Related Potentials
Authors: Akram Faraz , Alwakeel Ahmed , Alwakeel Mohammed , Hijji Mohammad , Masud Usman
Published: December 2022

Brain-Computer Interface (BCI) is a technique that allows the disabled to interact with a computer directly from their brain. P300 Event-Related Potentials (ERP) of the brain have widely been used in several applications of the BCIs such as character spelling, word typing, wheelchair control for the disabled, neurorehabilitation, and smart home control. Most of the work done for smart home control relies on an image flashing paradigm where six images are flashed randomly, and the users can select one of the images to control an object of interest. The shortcoming of such a scheme is that the users have only six commands available in a smart home to control. This article presents a symbol-based P300-BCI paradigm for controlling home appliances. The proposed paradigm comprises of a 12-symbols, from which users can choose one to represent their desired command in a smart home. The proposed paradigm allows users to control multiple home appliances from signals generated by the brain. The proposed paradigm also allows the users to make phone calls in a smart home environment. We put our smart home control system to the test with ten healthy volunteers, and the findings show that the proposed system can effectively operate home appliances through BCI. Using the random forest classifier, our participants had an average accuracy of 92.25 percent in controlling the home devices. As compared to the previous studies on the smart home control BCIs, the proposed paradigm gives the users more degree of freedom, and the users are not only able to control several home appliances but also have an option to dial a phone number and make a call inside the smart home. The proposed symbols-based smart home paradigm, along with the option of making a phone call, can effectively be used for controlling home through signals of the brain, as demonstrated by the results.
Low-Complexity Lossless Coding of Asynchronous Event Sequences for Low-Power Chip Integration
Authors: Schiopu Ionut , Bilcu Radu Ciprian
Published: December 2022

The event sensor provides high temporal resolution and generates large amounts of raw event data. Efficient low-complexity coding solutions are required for integration into low-power event-processing chips with limited memory. In this paper, a novel lossless compression method is proposed for encoding the event data represented as asynchronous event sequences. The proposed method employs only low-complexity coding techniques so that it is suitable for hardware implementation into low-power event-processing chips. A first, novel, contribution consists of a low-complexity coding scheme which uses a decision tree to reduce the representation range of the residual error. The decision tree is formed by using a triplet threshold parameter which divides the input data range into several coding ranges arranged at concentric distances from an initial prediction, so that the residual error of the true value information is represented by using a reduced number of bits. Another novel contribution consists of an improved representation, which divides the input sequence into same-timestamp subsequences, wherein each subsequence collects the same timestamp events in ascending order of the largest dimension of the event spatial information. The proposed same-timestamp representation replaces the event timestamp information with the same-timestamp subsequence length and encodes it together with the event spatial and polarity information into a different bitstream. Another novel contribution is the random access to any time window by using additional header information. The experimental evaluation on a highly variable event density dataset demonstrates that the proposed low-complexity lossless coding method provides an average improvement of 5.49%, 11.45%, and 35.57% compared with the state-of-the-art performance-oriented lossless data compression codecs Bzip2, LZMA, and ZLIB, respectively. To our knowledge, the paper proposes the first low-complexity lossless compression method for encoding asynchronous event sequences that are suitable for hardware implementation into low-power chips.
Automatic Time Picking for Weak Seismic Phase in the Strong Noise and Interference Environment: An Hybrid Method Based on Array Similarity
Authors: Wu Haofeng , Xiao Weiguo , Ren Haoran
Published: December 2022

The extraction of travel-time curve of seismic phase is very important for the subsequent inference of the structural properties of underground media in seismology. In recent years, with the increase in the amount of data, manual processing is facing significant challenges, and automatic signal processing has gradually become the mainstream. According to the similarity of array signals and considering the elimination of outliers, we propose an improved multi-channel cross-correlation method using the L1 norm measure to obtain preliminary results, which builds on a new controllable measurement mode. Then, the post-correction step is carried out in combination with the signal gain property of beamforming technique. Based on these two methods, this paper proposes a new scheme of automatic arrival time picking. We apply the scheme to actual data to verify the effects of the two methods step by step. The entire scheme achieves fine results: direct water waves, seismic waves refracted by the crust and seismic waves reflected by the upper mantle are automatically detected. In addition, compared with the two traditional methods, the scheme proposed in this paper has a better overall effect and a reasonable computation cost.

Published: December 2022

Wireless sensor network (WSN) deployment is an intensive field of research. In this paper, we propose a novel approach based on machine learning (ML) and metaheuristics (MH) for supporting decision-makers during the deployment process. We suggest optimizing node positions by introducing a new hybridized version of the “Hitchcock bird-inspired algorithm” (HBIA) metaheuristic algorithm that we named “Intensified-Hitchcock bird-inspired algorithm” (I-HBIA). During the optimization process, our fitness function focuses on received signal maximization between nodes and antennas. Signal estimations are provided by the machine learning “K Nearest Neighbors” (KNN) algorithm working with real measured data. To highlight our contribution, we compare the performances of the canonical HBIA algorithm and our I-HBIA algorithm on classical optimization benchmarks. We then evaluate the accuracy of signal predictions by the KNN algorithm on different maps. Finally, we couple KNN and I-HBIA to provide efficient deployment propositions according to actual measured signal on areas of interest.

Authors: Wang Pengfei , Wang Yixu , Xiang Jiafu , Xiao Xiaoling
Published: December 2022

Because images are vulnerable to external attacks in the process of network transmission and traditional image encryption algorithms have limitations such as long encryption time, insufficient entropy or poor diffusion of cipher image information when encrypting color images, a fast image encryption algorithm based on logistics-sine-cosine mapping is proposed. The algorithm first generates five sets of encrypted sequences from the logistics-sine-cosine mapping, then uses the order of the encryption sequence to scramble the image pixels and designs a new pixel diffusion network to further improve the key sensitivity and plain-image sensitivity of the encryption algorithm. Finally, in a series of security analysis experiments, the experimental image Lena was tested 100 times, and the average encryption time was 0.479 s. The average value of the information entropy, pixel change rate and uniform average change intensity of the cipher image reached 7.9994, 99.62% and 33.48%, respectively. The experimental results show that the fast image encryption algorithm based on logistics-sine-cosine mapping takes less time to encrypt, and the cipher image has good information entropy and diffusivity. It is a safe and effective fast image encryption algorithm.

Published: December 2022

Radar is widely employed in many applications, especially in autonomous driving. At present, radars are only designed as simple data collectors, and they are unable to meet new requirements for real-time and intelligent information processing as environmental complexity increases. It is inevitable that smart radar systems will need to be developed to deal with these challenges and digital twins in cyber-physical systems (CPS) have proven to be effective tools in many aspects. However, human involvement is closely related to radar technology and plays an important role in the operation and management of radars; thus, digital twins’ radars in CPS are insufficient to realize smart radar systems due to the inadequate consideration of human factors. ACP-based parallel intelligence in cyber-physical-social systems (CPSS) is used to construct a novel framework for smart radars, called Parallel Radars. A Parallel Radar consists of three main parts: a Descriptive Radar for constructing artificial radar systems in cyberspace, a Predictive Radar for conducting computational experiments with artificial systems, and a Prescriptive Radar for providing prescriptive control to both physical and artificial radars to complete parallel execution. To connect silos of data and protect data privacy, federated radars are proposed. Additionally, taking mines as an example, the application of Parallel Radars in autonomous driving is discussed in detail, and various experiments have been conducted to demonstrate the effectiveness of Parallel Radars.

Authors: Jeong Seongho , Jeong Seongkyun , Bong Jaehwan
Published: December 2022

As a result of climate change and global warming, plant diseases and pests are drawing attention because they are dispersing more quickly than ever before. The tomato leaf miner destroys the growth structure of the tomato, resulting in 80 to 100 percent tomato loss. Despite extensive efforts to prevent its spread, the tomato leaf miner can be found on most continents. To protect tomatoes from the tomato leaf miner, inspections must be performed on a regular basis throughout the tomato life cycle. To find a better deep neural network (DNN) approach for detecting tomato leaf miner, we investigated two DNN models for classification and segmentation. The same RGB images of tomato leaves captured from real-world agricultural sites were used to train the two DNN models. Precision, recall, and F1-score were used to compare the performance of two DNN models. In terms of diagnosing the tomato leaf miner, the DNN model for segmentation outperformed the DNN model for classification, with higher precision, recall, and F1-score values. Furthermore, there were no false negative cases in the prediction of the DNN model for segmentation, indicating that it is adequate for detecting plant diseases and pests.

Published: December 2022

Understanding the strain transfer mechanism is required to interpret strain sensing results for fiber optic cables. The strain transfer mechanism for fiber optic cables embedded in cementitious materials has yet to be thoroughly investigated experimentally. Interpretation of fiber optic sensing results is of particular concern when there is a displacement discontinuity. This study investigates the strain transfer mechanism for different types of fiber optic cables while embedded in concrete cubes, sustaining a boundary condition which features a displacement discontinuity. The strain transfer mechanisms for different cables are compared under increasing strain levels. Under cyclic loading, the nonlinear behavior of the force–displacement relation and of the strain distribution in the fiber optic cable are discussed. The mechanical properties of the fiber optic cables are presented and discussed. A parameter is proposed to quantify the strain transfer length. The results of this study will assist researchers and engineers to select appropriate cables for strain sensing and interpret the fiber optic sensing results.

Published: December 2022

A high-spatial-resolution OFDR distributed temperature sensor based on Au-SMF was experimentally demonstrated by using step-by-step and image wavelet denoising methods (IWDM). The measured temperature between 50 and 600 °C could be successfully demodulated by using SM-IWDM at a spatial resolution of 3.2 mm. The temperature sensitivity coefficient of the Au-SMF was 3.18 GHz/°C. The accuracy of the demodulated temperature was approximately 0.24 °C. Such a method has great potential to expand the temperature measurement range, which is very useful for high-temperature applications.
Urban DAS Data Processing and Its Preliminary Application to City Traffic Monitoring
Authors: Wang Hang , Chen Yunfeng , Min Rui , Chen Yangkang
Published: December 2022

Distributed acoustic sensing (DAS) is an emerging technology for recording vibration signals via the optical fibers buried in subsurface conduits. Its relatively easy-to-deploy and high spatial and temporal sampling characteristics make DAS an appealing tool to record seismic wavefields at higher quantity and quality than traditional geophones. Considering that the usage of optical fibers in the urban environment has drawn relatively less attention aside from its functionality as a telecommunication cable, we examine its ability to record seismic signals and investigate its preliminary application in city traffic monitoring. To solve the problems that DAS signals are prone to a variety of environmental noise and are generally of weak amplitude compared to noise, we propose a fast workflow for real-time DAS data processing, which can enhance the detection of regular car signals and suppress the other components. We conduct a DAS experiment in Hangzhou, China, a typical metropolitan area that can provide us with a rich data library to validate our DAS data-processing workflow. The well-processed data enable us to extract their slope and coherency attributes that can provide an estimate of real traffic situations. The one-minute (with video validations) and 24 h statistics of these attributes show that the speed and volume of car flow are well correlated demonstrates the robustness of the proposed data processing workflow and great potential of DAS for city traffic monitoring with high precision and convenience. However, challenges also exist in view that all the attributes are statistically analyzed based on the behaviors of a large number of cars, which is meaningful but lacking in precision. Therefore, we suggest developing more quantitative processing and analyzing methods to provide precise information on individual cars in future works.

Authors: Bokova Maria , Dumortier Steven , Poupin Christophe , Cousin Renaud , Kassem Mohammad , Bychkov Eugene
Published: December 2022

Chalcogenide glasses are widely used as sensitive membranes in the chemical sensors for heavy metal ions detection. The lack of research work on sodium ion-selective electrodes (Na+-ISEs) based on chalcogenide glasses is due to the high hygroscopicity of alkali dopes chalcogenides. However, sodium halide doped Ga2S3-GeS2 glasses are more chemically stable in water and could be used as Na+-sensitive membranes for the ISEs. In this work we have studied the physico-chemical properties of mixed cation (AgI)x(NaI)30-x(Ga2S3)26(GeS2)44 chalcogenide glasses (where x = 0, 7.5, 15, 22.5 and 30 mol.% AgI) using density, DSC, and conductivity measurements. The mixed cation effect with shallow conductivity and glass transition temperature minimum was found for silver fraction r = Ag/(Na + Ag) ≈ 0.5. Silver addition decreases the moisture resistance of the glasses. Only (AgI)22.5(NaI)7.5(Ga2S3)26(GeS2)44 composition was suitable for chemical sensors application, contrary to the single cation sodium halide doped Ga2S3-GeS2 glasses, where 15 mol.% sodium-halide-containing vitreous alloys are stable in water solutions. The analytical parameters of (NaCl)15(Ga2S3)23(GeS2)62; (NaI)15(Ga2S3)23(GeS2)62 and (AgI)22.5(NaI)7.5(Ga2S3)26(GeS2)44 glass compositions as active membranes in Na+-ISEs were investigated, including detection limit, sensitivity, linearity, ionic selectivity (in the presence of K+, Mg2+, Ca2+, Ba2+, and Zn2+ interfering cations), reproducibility and optimal pH-range.

Published: December 2022

Autonomous vehicles are the near future of the automobile industry. However, until they reach Level 5, humans and cars will share this intermediate future. Therefore, studying the transition between autonomous and manual modes is a fascinating topic. Automated vehicles may still need to occasionally hand the control to drivers due to technology limitations and legal requirements. This paper presents a study of driver behaviour in the transition between autonomous and manual modes using a CARLA simulator. To our knowledge, this is the first take-over study with transitions conducted on this simulator. For this purpose, we obtain driver gaze focalization and fuse it with the road’s semantic segmentation to track to where and when the user is paying attention, besides the actuators’ reaction-time measurements provided in the literature. To track gaze focalization in a non-intrusive and inexpensive way, we use a method based on a camera developed in previous works. We devised it with the OpenFace 2.0 toolkit and a NARMAX calibration method. It transforms the face parameters extracted by the toolkit into the point where the user is looking on the simulator scene. The study was carried out by different users using our simulator, which is composed of three screens, a steering wheel and pedals. We distributed this proposal in two different computer systems due to the computational cost of the simulator based on the CARLA simulator. The robot operating system (ROS) framework is in charge of the communication of both systems to provide portability and flexibility to the proposal. Results of the transition analysis are provided using state-of-the-art metrics and a novel driver situation-awareness metric for 20 users in two different scenarios.
An Experimental Study on Simultaneous Use of Metal Fins and Mirror to Improve the Performance of Photovoltaic Panels
Authors: Firoozzadeh Mohammad , Lotfi Marzieh , Shiravi Amir Hossein
Published: December 2022

The world is inconceivable without an everlasting demand for energy. Nowadays, various kinds of renewable energies, such as solar energy, are developing rapidly, since they have the least negative environmental impacts. Irradiation intensity is one the most important parameters in photovoltaic (PV) technology, and so integration of mirrors with a PV module can improve its performance. Mounting mirrors increases the radiation intensity but, at the same time, raises the surface temperature, which in turn reduces the electrical efficiency. The novelty of this study is keeping the cell temperature low despite receiving more radiation by installing 10 aluminum fins on the back of the panel. All tests were experimentally performed in the hot climate of Dezful, Iran. As a result, the best tilt angle of the mirror was found at 30°, where the output power was enhanced by 3.3% and electrical efficiency was reduced by 0.5% compared with the conventional case. When aluminum fins were added as heat sinks, both output power and electrical efficiency were enhanced by 11.4% and 13.1%, respectively. Moreover, comprehensive discussions on both energy and exergy are provided. The entropy generation was also calculated and accordingly, the case of PV 30 + fin generates 1.6% less entropy than the base one.
Influence of Thermal Behavior on the Safety Performance of the Pit Enclosure near Railway Foundations under Solar Radiation
Authors: Wang Wanqi
Published: December 2022

Thermal behavior often affects the performance of thin-walled steel structures and even becomes one of the controlling loads. Steel pipes are often used in foundation pit support. This problem of the thermal stress of steel pipes is very important. The Huhang Railway, a section of the high-speed railway from Huzhou to Hangzhou in Zhejiang Province, China, was examined in this study. In this paper, the displacement and stress in pit 358# of the Huhang Railway near the railway foundation was monitored, and a thermal coupling model was established. The temperature field distribution inside the foundation pit was calculated through solar radiation and ambient temperature, and the displacement and stress of the supporting structure and enclosure structure were calculated using the thermal expansion coefficient. The following conclusions were drawn from the comparison: (1) In addition to solar radiation, ambient radiation should also be taken into account at the same time, especially in the calculation of the substructure. (2) The temperature of the support structure was unevenly distributed, and the maximum temperature difference between the steel pipes on the east and west sides could reach from 18.9 °C up to 58.8 °C. The height angle of solar radiation was the main factor that led to this situation. (3) The difference in stress between the support structure and the enclosure structure was positively related to the change in temperature. When the temperature rose, the stress increased, and the horizontal displacement of the enclosure structure decreased, which was beneficial to the stability of the foundation pit and vice versa. (4) The thermal behavior had different effects on the stress at different depths and times, and had spatial and temporal heterogeneity. The enclosure stresses had a certain delay in response to temperature changes. The reasons for this are yet to be investigated.
Tackling Fuzziness in CSR Communication Research on Social Media: Pathways to More Rigor and Replicability
Authors: Schacker Maximilian
Published: December 2022

Research analyzing the antecedents and effects of CSR communication on social media based on real-world data has surged in recent years but suffers from a severe lack of construct clarity. Based on an extensive literature review and the analysis of intercoder congruency on a content classification task on Instagram, we argue that CSR communication is a fuzzy concept and that diverging theoretical conceptions of CSR and CSR relatedness, as well as different operationalizations, have led to highly inconsistent and difficult-to-replicate results. To improve rigor and replicability in future CSR communication research using social media analytics, we develop guidelines for identifying CSR communication on social media that address common pitfalls in existing research designs.

The article presents a modification of the EOQ formula for a model with rental of storage facilities, which will allow managers operating in the conditions of crisis reconfiguration of supply chains to find the optimal inventory management strategy, taking into account the combined impact of a number of factors: the capacity of the vehicle, the time value of money when optimizing supplies and financial losses associated with funds frozen in stocks. The procedures for modifying the EOQ formula for such situations are carried out in relation to models important for practice, when payment for the order and the corresponding transaction costs of the supply chain are realized from the revenue received at the re-order interval. At the same time, necessary and sufficient conditions have been established based on which managers will be able to identify models of the specified type. The purpose of the article is to draw the attention of managers to additional opportunities to improve the efficiency of inventory management systems in modern business development conditions by considering these factors when optimizing supplies.

Published: December 2022

Provinsi Jawa Barat memiliki tingkat kerawanan bencana paling tinggi di Indonesia yang di dominasi  oleh kejadian tanah longsor, banjir dan kebakaran. Kelompok yang sangat rentan terhadap bencana adalah anak-anak. Anak-anak sekolah dasar rata-rata menghabiskan waktu 7 jam di sekolah. Sehingga sekolah dapat dikategorikan sebagai tempat yang rawan bencana. Bencana dapat terjadi setiap saat termasuk pada saat anak di sekolah. Anak sekolah harus memiliki ketangguhan dalam menghadapi ancaman bencana. School Watching merupakan salah satu metode yang dapat membantu peserta didik dalam meningkatkan kesiapsiagaan bencana melalui kegiatan yang dilakukan di sekolah dan lingkungan sekitarnya. Penelitian ini bertujuan untuk mengetahui pengaruh metode school watching terhadap kesiapsiagaan siswa SD dalam menghadapi bencana di Kecamatan Cicendo Kota Bandung. Desain penelitian menggunakan quasi experiment dengan pendekatan Pre Post test control group design. Sampel Penelitian ini siswa kelas V SD di Kecamatan Cicendo. Besar sampel berjumlah 39 orang untuk kelompok intervensi dan 39 orang untuk kelompok kontrol. Teknik pengambilan sampel dengan cara proportional Random sampling. Intervensi diberikan dalam 5 kali pertemuan. Kegiatan intervensi meliputi: pemberian materi tentang kebencanaan, pengamatan, pemetaan, diskusi dan presentasi. Analisis data yang digunakan untuk kelompok berpasangan menggunakan  uji statistik T test dependent karena data berdistribusi normal. Sedangkan untuk kelompok tidak berpasangan menggunakan uji Mann-Whitney karena data berdistribusi tidak normal. Hasil penelitian menunjukkan terdapat pengaruh metode school watching terhadap kesiapsiagaan siswa SD dalam menghadapi bencana karena didapatkan p value 0,000. Oleh karena itu disarankan kepada penanggung jawab program kesehatan sekolah untuk menerapkan metode school watching untuk mengurangi resiko bencana di komunitas sekolah.
Ulysses proficiens. A reassessment of Seneca’s reading
Authors: Donne Carlo G. Delle
Published: December 2022

This article offers a new reading of Seneca’s Ulysses. He will be proven not to stand for the Stoic hero, the symbol of virtue; rather, he will turn out to represent the proficiens – those who make any effort to reach virtue, and yet sometimes fail. In this regard, Ulysses is like Seneca himself, in as much as both of them appear to do their best to face the impetuous waves of fortune.
Algunas expresiones de la desigualdad en Siria-Palestina durante la Edad del Bronce Tardío
Authors: Pfoh Emanuel
Published: December 2022

El Cercano Oriente, junto con el valle del Nilo, constituyen dos de las primeras locaciones en las que la desigualdad institucionalizada apareció por primera vez,alrededor de finales del IV milenio a.n.e. Siria-Palestina, como región combinada, fue siempre periférica a los procesos históricos y sociopolíticos que ocurríanen la Baja Mesopotamia y Egipto. No obstante, y aunque un poco más tarde, la desigualdad económica y política también apareció en la región, plenamentedesarrollada ya durante la Edad del Bronce Antiguo, con la aparición de los primeros centros urbanos. Las relaciones personales dentro de las comunidadespolíticas y hacia el exterior (el trato con los poderes superiores), parece ser el modo establecido y regular de comportamiento político (no hay pruebas de leyesescritas, ni de aparatos estatales para controlar a la población). En comparación con Siria, Palestina tiene un desarrollo urbano mucho más modesto y menosevidencia de organizaciones complejas en los sitios urbanos. Es posible argumentar, pues, acerca de la existencia de una ontología política autóctona basadaen las relaciones personales y jerárquicas, como los vínculos patrón-cliente. La política era profundamente jerárquica (desigual), pero también estaba ligada a lareciprocidad, expresada por un intercambio de protección y lealtad. Esta ontología política informaba también la imaginación divina y cosmológica: el reinohumano se incorpora al reino divino, siendo el rey sirio un intermediario (en realidad el único intermediario) entre los dioses y su comunidad. En Palestina,dicha intermediación se encuentra evidenciada sólo en el plano humano.
Una antropología política para Creta Neopalacial
Authors: Cano Moreno Jorge
Published: December 2022

El estudio de las relaciones políticas en la isla de Creta durante gran parte de la Edad de Bronce ha generado algunos de los debates más longevos enla arqueología del Mediterráneo oriental. Esto se debe –mayormente– a la ausencia de fuentes escritas descifradas, a las peculiaridades historiográficasque ha tenido el estudio de la cultura minoica y a la compleja naturaleza de la evidencia arqueológica de la isla.Ante esto, este trabajo tiene al menos tres propósitos: el primero es hacer una revisión de los modelos políticos utilizados para el período Neopalacial (ca.1700-1450 a.C.) en la isla de Creta; en segundo lugar, busca resaltar las nuevas tendencias teóricas sobre este tópico marcando sus respectivos puntos fuertesy sus posibles falencias argumentativas; por último, tiene la intención de enfatizar el valor de las dinámicas sociales por sobre los esquemas ideados por losacadémicos que han abordado esta problemática. De este modo, se concluirá presentando cuáles son las dinámicas de poder político más importantes duranteel período Neopalacial que se han marcado hasta el momento y se destacará por qué es necesario introducir algunos postulados de la antropología políticaen este debate.

ASPECTS OF THE IMPORTANCE OF FIRST METATARSOPHALANGEAL JOINT IN THE PROCESS OF GAIT RECOVERY
Authors: Murgoci Nicolae , Mereuță Claudiu
Published: December 2022

The purpose of the present scientific research is to take into consideration the importance of rehabilitation of the first metatarsophalangeal joint in the process of physio cycling in order to recover the gait. Hypothesis: patients over 55 age has hallux rigidus that determine the vicious angulation of the ankle by reduction of the normal range of motion. The aim of this research is to analyses the possibility of applying kinetic programs for the first metatarsophalangeal joint too, in the process of horizontal cycling. Recovering the independence of gait in order to improve the quality of life it is a crucial factor of rehabilitation. Materials and Methods: 19 patients over 55 years age, period November 2020- March 2021 diagnosed with different pathologies (excluding amputation) that affects lower limbs and with indication for physiotherapy and Visual Analog Scale maxim 4. Determination of active dorsiflexion and active plantarflexion of the first metatarsophalangeal joint was proceed according to American Medical Association scale of grading. Pearson correlation between right and left foot of the first metatarsophalangeal joint are strong. The most common grade is 3 both for left and right foot on dorsiflexion and plantarflexion, approximately equal distribution on gender. Kinetic program can be used only for the first 3 grades according AMA and hallux rigidus severity grades 0-2. In the process of gait recovery may be possible physiotherapy for 12 patients for the 1st MTF joint among the other programs for kinetic chain.
EXERCISE AND HEALTHY LIFE EXPECTANCY
Authors: Hagiu Bogdan Alexandru
Published: December 2022

There is a consensus in the literature on the role of exercise in prolonging healthy life. The strongest effect is held by sports games characterized by intense efforts. As a result, the paper proposes the analysis of anaerobic and aerobic efforts on the release of myokines and stem cell metabolism. Anaerobic exercise should play a significant role in anti-aging programs, as it stimulates muscle secretion of bone morphogenetic protein 7, a myokine that helps prevent cardiovascular diseases, the main cause of mortality. Intense exercise also strongly stimulates the release of irisin, IL-6, IL-15 and progenitor stem cells, which is why they should be given a higher weight in anti-aging training programs and kinetoprophylaxis of the elderly. Anaerobic exercise may prevent myostatin (myokine that accelerates the aging of striated muscle) from growing more than aerobic ones. IGF-1, whose role in increasing life expectancy is controversial, and which is not secreted during aerobic exercise, appears to be only redistributed in plasma as a result of resistance exercise.
