LOCAL RESOURCE-BASED INDUSTRIES AND RURAL DEVELOPMENT: A STUDY IN THE DISTRICT OF DHUBRI IN ASSAM
Authors: Karmakar Dulal C
Published: June 2023

India cannot be developed without development in rural areas. Villages of the country are backward in every respect. Agriculture is the backbone for each of the rural economy. Dhubri district in Assam is not an exception to the general features of the villages of the country. Development of the district is not possible without active participation of the rural people in the channel of economic activities. Main objectives of the study are to know the utilisation of local resources to form resource-based industries and development in rural areas and to recommend suggestions to make utilisation of local resources for economic development. Study is based on secondary data, observation, and interaction with the rural people. In the district, growth rate of population is very high, and it is 24.44 percent. 89.55% people of the district live in rural areas. Literacy rate of the district is as low as 58.34 percent. The district is poor very poor and lagging other districts of the state. All-round development in the villages can be achieved with the establishment of local resource-based industrialisation. But this process involves several problems in rural areas like unskilled labour, rural poverty, infrastructural bottlenecks, flood problem, lack of training institute, etc. The mighty Brahmaputra flows along the district and this is boon for the district. Water can be utilised for fishery, irrigation in agricultural field and water transport purpose. There is huge production in agricultural field due to alluvial soil on the bank of the river Brahmaputra. So, there is greater possibility of growing agro-based industries. With the utilisation of local resources with people’s active participation and eliminating all hurdles faced on the path, rural economic development can be possible.

Authors: Nikolaeva E. A. , Martynyuk T. V.
Published: June 2023

The updated 2022 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension approved new criteria for diagnosis of pulmonary hypertension (PH). In this review we present the data from modern studies proving the expediency of changing the threshold values of hemodynamic parameters measured by right heart catheterization (RHC) and echocardiography for the diagnosis of PH, the importance of introduction the definition «exercise PH» into clinical practice.

New haemodynamic definition of pulmonary arterial hypertension: mean pulmonary arterial pressure (mPAP) > 20 mmHg, pulmonary arterial wedge pressure < 15 mmHg, pulmonary vascular resistance (PVR) > 2 Wood units, measured by RHC at rest. Diagnostic levels of systolic pulmonary arterial pressure and tricuspid regurgitation velocity measured by echocardiography stay the same, but it is important to combine them with a number of additional echocardiographic signs of PH.

Promising direction for early diagnosis of PH is RHC during exercise in addition to studies at rest. Nowadays there are no generally accepted diagnostic criteria for exercise PH. Some studies propose the following threshold values of exercise PH: mPAP > 30 mmHg and PVR > 3 Wood units during exercise.

Pulmonary veno-occlusive disease (PVOD) is verified by identifying typical pathological changes in lungs or mutation in the EIF2AK4 gene. Clinical suspicion is based on combination of specific pulmonary pattern on computed tomography scan, hypoxemia with low diffusing lung capacity (DLCO) and inadequate response to specific therapy of pulmonary arterial hypertension (PAH). The rapid course of PVOD with high mortality determines the importance of early diagnosis and lung transplantation refferal.

We present an unusual clinical case of 40-year-old woman with expected idiopathic PAH and extremely low DLCO with verified EIF2AK4 gene mutation, who demonstrated a positive vasoreactive test (VRT) and clinical response to calcium channel blockers therapy at the onset of the disease. The loss of positive VRT and subsequent PAH specific therapy escalation resulted in PVOD manifestation with severe desaturation, recurrent syncope and pulmonary edema. The combination of low DLCO and inadequate response to PAH therapy in idiopathic PAH patient should be of a paramount awareness of PVOD. Careful PAH therapy escalation with meticulous follow-up, pulmonary multispiral CT and genetic testing could improve early PVOD diagnostics and lung transplantation referral.

The clinical significance of renovascular arterial hypertension is determined by it is high prevalence as well as it is negative impact on prognosis. The most common causes of renovascular arterial hypertension are atherosclerotic stenosis of the renal arteries and fibromuscular dysplasia. Renovascular arterial hypertension is characterized by the development of blood pressure resistant to antihypertensive therapy with an unfavorable prognosis of worsening renal function and cardiovascular complications. Currently, the most available screening method in the diagnosis of renovascular arterial hypertension is duplex scanning of the renal arteries. Non-invasive diagnostic methods also include magnetic resonance and multispiral computed tomography with intravenous contrast. Contrast angiography remains “the golden standard” for diagnosing renovascular arterial hypertension and determining the indications for surgical treatment. Together with the use of diagnostic techniques such as measurement of translesion pressure gradient and fractional blood flow reserve, it allows to assess the functional significance of renal artery stenosis. Treatment of renovascular arterial hypertension is a complex process aimed at normalization of blood pressure, improvement of renal function, as well as mortality and cardiovascular risk reduction. To date, the feasibility of endovascular treatment remains an open question. More often the preference is given to conservative treatment. The indications for renal artery revascularization are less obvious, available clinical guidelines and results of large trials are controversial.

Published: June 2023

Infrastructure is the most important thing in the progress of a country. Several countries in the world have been able to develop forward thanks to a strong infrastructure foundation supported by good synergies between government companies and the private sector. Infrastructure development is an important matter in the process of growing a nation in the economic, educational, social, cultural, agricultural, and other sectors. This study aims to determine the effect of sales growth and DAR (Debt to Assets Ratio) on company profitability (Return on Asset). This research was conducted on infrastructure sector companies listed on the Indonesia Stock Exchange for 2020-2022. The population in this study are all infrastructure companies listed on the Indonesia Stock Exchange (IDX) for 2020-2022, totaling 37 companies. The sample selection used a purposive sampling technique with several predetermined criteria, so the number of samples was 11 companies. The research data is secondary data obtained from the Indonesian Stock Exchange (IDX) 2020-2022. Data were analyzed using panel data regression with the help of Stata software version 14 to determine the significant level of each independent variable regression coefficient to the dependent. The results showed that sales growth and DAR (Debt to Asset Ratio) simultaneously had a positive effect on company profitability (Return on Asset). Sales growth has no effect on profitability, and DAR (Debt to Asset Ratio) has a negative effect on company profitability (Return on Asset).

Published: June 2023

Taxes are a source of state financing that contributes greatly in carrying out state development for the welfare of all Indonesian people. The application of the self-assessment system plays a role in tax collection and has a very important role. Taxpayers have the trust, responsibility and authority to calculate, pay and report taxes. Taxpayers who have a Taxpayer Identification Number are expected to be active in fulfilling their obligations. This study aims to determine taxpayer compliance, especially Taxable Entrepreneurs in carrying out their tax obligations. The method used is a qualitative research method. The results of the study show that in fulfilling tax obligations Taxable Entrepreneurs does so based on applicable regulations and fulfills the specified conditions, namely registering as a taxpayer, submitting SPT on time, making correct reporting, and not having tax arrears. However, in carrying out their tax obligations, Taxable Entrepreneurs still has obstacles such as the busy network of the Directorate General of Taxes (DGT) which makes it difficult to access, besides that the lack of understanding of taxes is also an obstacle they face. To overcome obstacles in the form of a network, taxpayers try to fulfill their tax obligations before the specified deadline to avoid the DGT's network being busy. As for the lack of understanding, taxpayers use the services of a tax consultant to occasionally ask questions and assist them in carrying out their tax obligations.

We present Keck Planet Imager and Characterizer (KPIC) high-resolution (R ∼35,000) K-band thermal emission spectroscopy of the ultrahot Jupiter WASP-33b. The use of KPIC’s single-mode fibers greatly improves both blaze and line-spread stabilities relative to slit spectrographs, enhancing the cross-correlation detection strength. We retrieve the dayside emission spectrum with a nested-sampling pipeline, which fits for orbital parameters, the atmospheric pressure–temperature profile, and the molecular abundances. We strongly detect the thermally inverted dayside and measure mass-mixing ratios for CO (

These observations demonstrate KPIC’s ability to characterize close-in planets and the utility of KPIC’s improved instrumental stability for cross-correlation techniques.

Studying the physical and chemical conditions of young embedded disks is crucial to constrain the initial conditions for planet formation. Here we present Atacama Large Millimeter/submillimeter Array observations of dust continuum at ∼0.″06 (8 au) resolution and molecular line emission at ∼0.″17 (24 au) resolution toward the Class 0 protostar L1527 IRS from the Large Program eDisk (Early Planet Formation in Embedded Disks). The continuum emission is smooth without substructures but asymmetric along both the major and minor axes of the disk as previously observed. The detected lines of 12CO, 13CO, C18O, H2CO, c-C3H2, SO, SiO, and DCN trace different components of the protostellar system, with a disk wind potentially visible in 12CO. The 13CO brightness temperature and the H2CO line ratio confirm that the disk is too warm for CO freezeout, with the snowline located at ∼350 au in the envelope. Both molecules show potential evidence of a temperature increase around the disk–envelope interface. SO seems to originate predominantly in UV-irradiated regions such as the disk surface and the outflow cavity walls rather than at the disk–envelope interface as previously suggested. Finally, the continuum asymmetry along the minor axis is consistent with the inclination derived from the large-scale (100″ or 14,000 au) outflow, but opposite to that based on the molecular jet and envelope emission, suggesting a misalignment in the system. Overall, these results highlight the importance of observing multiple molecular species in multiple transitions to characterize the physical and chemical environment of young disks.
Identification of Extended Emission Gamma-Ray Burst Candidates Using Machine Learning

Published: June 2023

Gamma-ray bursts (GRBs) have been classified traditionally based on their duration. The increasing number of extended emission (EE) GRBs, lasting typically more than 2s but with properties similar to those of short GRBs, challenges the traditional classification criteria. In this work, we use the t-distributed stochastic neighbor embedding (t-SNE), a machine-learning technique, to classify GRBs. We present the results for GRBs observed until 2022 July by the Swift/BAT (Burst Alert Telescope)  instrument in all its energy bands. We show the effects of varying the learning rate and perplexity parameters as well as the benefit of preprocessing the data by a nonparametric noise-reduction technique. Consistently with previous works, we show that the t-SNE method separates GRBs into two subgroups. We also show that EE GRBs reported by various authors under different criteria tend to cluster in a few regions of our t-SNE maps and identify seven new EE GRB candidates by using the gamma-ray data provided by the automatic pipeline of Swift/BAT and the proximity with previously identified EE GRBs.
Neutron Star Phase Transition as the Origin for the Fast Radio Bursts and Soft Gamma-Ray Repeaters of SGR J1935 + 2154
Authors: Shen Jun-Yi , Zou Yuan-Chuan , Yang Shu-Hua , Zheng Xiao-Ping , Wang Kai
Published: June 2023

Magnetars are believed to be neutron stars (NSs) with strong magnetic fields. X-ray flares and fast radio bursts (FRBs) have been observed from the magnetar (soft gamma-ray repeater, SGR J1935+2154). We propose that the phase transition of the NS can power the FRBs and SGRs. Based on the equation of state provided by the MIT bag model and the mean field approximation, we solve the Tolman–Oppenheimer–Volkoff equations to get the NS structure. With the spin-down of the NS, the hadronic shell gradually transfers to the quark shell. The gravitational potential energy released by one time of the phase transition can be achieved. The released energy, time interval between two successive phase transitions, and glitch are all consistent with the observations of the FRBs and the X-ray flares from SGR J1935 + 2154. We conclude that the phase transition of an NS is a plausible mechanism to power the SGRs as well as the repeating FRBs.
Delensing of Cosmic Microwave Background Polarization with Machine Learning

Published: June 2023

Primordial B-mode detection is one of the main goals of next-generation cosmic microwave background (CMB) experiments. Primordial B-modes are a unique signature of primordial gravitational waves (PGWs). However, the gravitational interaction of CMB photons with large-scale structures will distort the primordial E modes, adding a lensing B-mode component to the primordial B-mode signal. Removing the lensing effect (“delensing”) from observed CMB polarization maps will be necessary to improve the constraint of PGWs and obtain a primordial E-mode signal. Here, we introduce a deep convolutional neural network model named multi-input multi-output U-net (MIMO-UNet) to perform CMB delensing. The networks are trained on simulated CMB maps with size 20° × 20°. We first use MIMO-UNet to reconstruct the unlensing CMB polarization (Q and U) maps from observed CMB maps. The recovered E-mode power spectrum exhibits excellent agreement with the primordial EE power spectrum. The recovery of the primordial B-mode power spectrum for noise levels of 0, 1, and 2 μK-arcmin is greater than 98% at the angular scale of ℓ < 150. We additionally reconstruct the lensing B map from observed CMB maps. The recovery of the lensing B-mode power spectrum is greater than roughly 99% at the scales of ℓ > 200. We delens the observed B-mode power spectrum by subtracting the reconstructed lensing B-mode spectrum. The recovery of tensor B-mode power spectrum for noise levels of 0, 1, and 2 μK-arcmin is greater than 98% at the angular scales of ℓ < 120. Even at ℓ = 160, the recovery of tensor B-mode power spectrum is still around 71%.
Mechanical Modification of Chondrule Fine-grained Rims by Dusty Nebular Shocks
Authors: Carballido Augusto , Matthews Lorin S. , Hanna Romy D. , Hyde Truell W.
Published: June 2023

The mechanical processes that convert an initially fluffy chondrule fine-grained rim (FGR) into a more compact structure remain poorly characterized. Given the presence of shocks in protoplanetary disks, we use numerical simulations to test the hypothesis that dust-laden shocks in the solar nebula contributed to FGR modification. We use the iSALE2D shock physics code to model the collision of dusty nebular shock fronts (which we term “dust clouds”) into chondrule surfaces that host a porous FGR. In our simulations, dust particles are modeled as dunite disks. The dust radii follow the Mathis–Rumpl–Nordsieck distribution of interstellar grains. Chondrules are modeled as rectangular dunite slabs. We vary the impact speed v
imp, the fractional abundance f
cloud of dust grains in the impacting shock, and the fractional abundance f
FGR of dust grains in the pre-existing FGR. We thus compute dust temperatures and pressures resulting from the collisions, as well as the net mass accretion of dust by the FGRs. Dust temperatures increase upon impact, depending on the kinetic energy of the dust cloud and on f
FGR. Dust rims with a higher f
FGR heat up more than those with a lower f
FGR, with possibly important implications for the composition and structure of FGRs. Maximum impact pressures increase with f
cloud. Fine-grained rims can experience mass gain from the impacting cloud, but in some instances, mass is lost from the rim. We find qualitative similarities in the topography of the FGR–chondrule interface between our simulations and petrographic analyses of the Paris CM chondrite by other authors.

The hybird methods of projection-splitting for solving tensor split feasibility problem
Authors: Xie Yajun , Ma Changfeng
Published: June 2023

Projection-type methods are studied widely and deeply to solve multiples-sets split feasibility problem. From the perspective of splitting iteration, in this paper, the efficient tensor projection-splitting iteration methods are firstly investigated for solving tensor split feasibility problem, which is properly transformed into a tensor equation by taking advantage of projection operator. Then, accelerated overrelaxation method and symmetric (alternating) accelerated overrelaxation method are further generalized to solve this problem from general system of linear equations to multi-linear systems. Theoretically, the convergence is proven by the analysis of spectral radius of splitting iteration tensor. Numerical experiments demonstrate the efficiency of the presented method.

Published: June 2023

The single valued neutrosophic probabilistic hesitant fuzzy rough Einstein aggregation operator (SV-NPHFRE-AO) is an extension of the neutrosophic probabilistic hesitant fuzzy rough set theory. It is a powerful decision-making tool that combines the concepts of neutrosophic logic, probability theory, hesitant fuzzy sets, rough sets, and Einstein aggregation operators. SV-NPHFRE-AO can be applied in many fields, including livestock decision making. Making judgments about a wide range of issues, including feed formulation, breeding program design, disease diagnostics, and market analysis, is part of the process of managing livestock. By combining data from many sources, SV-NPHFRE-AO can assist decision-makers in livestock management in integrating and evaluating diverse criteria, which can result in more informed choices. It also provides a more accurate and comprehensive representation of decision-making problems by considering the multiple criteria involved and the relationships between them. The single valued neutrosophic set (SV-NS) aggregation operators (AOs) based on Einstein properties using hesitant fuzzy sets (HFSs) and probabilistic hesitant fuzzy sets (PHFSs) with rough sets (RSs) are proposed in this study and can handle a large volume of data, making them suitable for complex and large-scale livestock decision-making problems. We first defined SV-neutrosophic probabilistic hesitant fuzzy rough weighted averaging (SV-NPHFRWA), SV-neutrosophic probabilistic hesitant fuzzy rough weighted geometric (SV-NPHFRWG), SV-neutrosophic probabilistic hesitant fuzzy rough ordered weighted averaging (SV-NPHFROWA) and SV-neutrosophic probabilistic hesitant fuzzy rough hybrid weighted averaging (SV-NPHFRHWA) AOs. Then, based on Einstein properties, we extended these operators and developed the single-valued neutrosophic probabilistic hesitant fuzzy rough Einstein weighted averaging (SV-NPHFREWA) operator. Additionally, an illustrative scenario to show the applicability of the suggested decision-making approach is provided, along with a sensitivity analysis and comparison analysis, which demonstrate that its outcomes are realistic and reliable. We also provide another relation between criteria and alternatives of decision-making using neutrosophic information with quaternion context. By using such type of operators, livestock managers can make more informed decisions, leading to better animal health, higher productivity, and increased profitability.

The Performance of Sensitivity-Maps Method in Reconstructing Low Contrast and Multi-Contrast Objects for Microwave Imaging Applications
Authors: Basari  , Ramdani Syahrul
Published: June 2023

The microwave imaging system for breast tumor/cancer detection requires high sensitivity to detect abnormal tissue that has little contrast in high-density breasts. This paper proposes a qualitative microwave imaging system simulation based on inverse scattering using the sensitivity-maps method. This method utilizes two measurement types for system calibration: a reference object as a scatterer-free background and a calibration object to obtain the system's impulse response. The object under test (OUT) consists of an object with low dielectric contrast and a phantom with multiple low dielectric contrasts (multi-contrast). Reconstruction is carried out on three types of S-parameter measurement data, namely S_11,〖 S〗_21, and a combination of both. S-parameters are measured at several frequencies, which are 3, 10, 14, 15, 16, 20 GHz, and the combination of all those frequencies (multifrequency). Reconstructed images show that the system is capable of reconstructing dielectric objects accurately. Quantitatively, the results show that the multifrequency S_21 measurement yields the best image quality with relative root mean squared error (RRMSE) values of 0.1272 and structural similarity index (SSIM) of 0.9076. The designed imaging system also successfully reconstructs multi-contrast phantom accurately with RRMSE of 0.1434 and SSIM of 0.4609.

Authors: Astudillo Alejandro , Avella-Rodríguez Edna , Arango-Hoyos Gloria , Ramirez-Scarpetta Jose , Rosero Esteban
Published: June 2023

This paper presents a wearable virtual reality system with a wireless network of inertial sensors for lower limb monitoring. The system comprises seven sensor nodes sending data wirelessly to a master node. The information is then collected, organized, and sent to a screening device via a serial interface. An application executed either on a smartphone or a personal computer features an avatar which represents the received data and mimics the sensed movements of the patient, providing online feedback during and after the execution of a therapy. The data resulting from the therapy execution can be uploaded to a web server to facilitate the assessment and decision-making by health professionals. A pendulum featuring a rotary optical encoder is used for sensor functional behavior validation.  In addition, the orientation angles measured by the proposed system are compared with respect to measurements from the motion analysis software Kinovea. The delay between the patient's body movement and the avatar is 33 ms, which is acceptable for visual feedback. This system is portable, inexpensive and enables a patient to complete physical therapy sessions at home or anywhere, with the advantage of enabling visual feedback through an avatar during rehabilitation therapy and allowing the reproduction of a therapy session for further analysis.
Quel(s) rapport(s) au marché du travail des élèves inscrits en Certificat d’Aptitude Professionnelle (CAP) ?
Authors: Bonnard Claire
Published: June 2023

Si des travaux ont montré une diversité de rapports à l’école et aux savoirs des élèves de l’enseignement professionnel, peu d’entre eux ont cherché à étudier le rapport au marché du travail de ces élèves. Cet article propose d’analyser la relation entre rapport à l'école et au marché du travail des élèves inscrits en CAP. Pour cela, une enquête a été réalisée portant sur 750 élèves inscrits en CAP sous voie scolaire et en apprentissage. Une typologie permet d’identifier quatre « profils-types » d’élèves qui se distinguent selon leur rapport à l’école et au marché du travail. Les résultats soulignent qu’un rapport plutôt positif ou négatif à l’école peut renvoyer à des finalités différentes et demande à être appréhendé selon la valeur accordée au diplôme et les opportunités perçues par l’élève sur le marché du travail. Ces différents rapports vont se construire de manière différenciée selon le genre, le statut migratoire, le parcours d’orientation ainsi que le contexte social et scolaire de l’élève.
Chefs d’établissements scolaires privés du premier degré multisites
Authors: Grave Bruno
Published: June 2023

La dynamique de professionnalisation des chefs d’établissements catholiques d’enseignement (CESP)(Enseignement Privé sous contrat en France) les entrainent depuis plusieurs années à prendre en charge des regroupements multisites. Dans le premier degré, cela se traduit par la mise en place de CESP sur plusieurs écoles d’une même entité géographique. Dès lors, ne pouvant se trouver sur les divers lieux à la fois, les CESP organisent, pour pallier leur absence, le fonctionnement et la vie des écoles, en s’appuyant sur les ressources humaines de chaque lieu. La complémentarité subsidiarité/délégation devient alors le principe central de la gouvernance et de l’action managériale du CESP. La mise en œuvre de ce principe produit un ensemble systémique d’ajustements réalisés à différentes échelles, de l’action individuelle aux réglages instruits dans chaque école à l’action institutionnelle des réglages instruits par les CESP en réseaux et par les tutelles qui l’érigent en stratégie politique. Notre étude rapporte, à partir du propos des acteurs, les effets de quelques ajustements réalisés à différentes échelles de la conception et de la mise en œuvre de cette gouvernance multisite.
Le manager-ingénieur face aux tensions entre innovation et organisation
Authors: Trébucq Stéphane , Hdayed Youssra , Atanasov Petko
Published: June 2023

Partant du cas d’un manager-ingénieur gérant l’implantation d’une nouvelle infrastructure de communication dans une centrale nucléaire, nous montrons comment ce dernier surmonte diverses contradictions au sein d’un réseau d’acteurs. Les objectifs d’amélioration de la mobilité et de la créativité se heurtent aux impératifs d’organisation visant à assurer la sécurité et la sûreté. Le manager compose alors avec le réseau des acteurs en place, en tentant de les convaincre et de faciliter leur adhésion. Si les personnels manifestent des difficultés à anticiper de nouvelles pratiques, l’implantation est considérée techniquement comme une réussite. Elle ne permet pourtant pas de résoudre les difficultés organisationnelles présentes initialement qui dépassaient le périmètre du projet géré par le manager-ingénieur.

Published: June 2023

Information and communication technologies are being used as weapons in a combat zone created by the norm that forces individuals to work from home during this pandemic. The upsurge in workplace cyberbullying is visible in various reports. Workplace cyberbullying may appear to be a less severe form of harassment, but the shift to a more dispersed workforce has made it worse. It is the intimidation experienced by a remote or hybrid employee which results in a breakdown in communication with or mistreatment from leaders. While it makes sense to believe that because we are not at the office, occurrences of antagonism and harassment are drastically reduced, that's not the reality. Spiteful employers and demeaning coworkers might pose a virtual threat. Remote work settings are becoming toxic due to harmful, unkind workplace behavior, including derogatory language, social exclusion, and threats via phone, email, or social media. This chapter unveils a new dimension of cyberology.

Published: June 2023

The Dark Web is a difficult and anonymous network used by cybercriminals, terrorists, and state-sponsored agents to carry out their illicit goals. Dark web cybercrime is very similar to offline crime. However, the vastness of the Dark Web, its unpredictable ecology, and the anonymity it provides are all obstacles that must be overcome in order to track down criminals. To reach the dark web, which is not indexed by search engines, you must use the anonymous Tor browser. The anonymity and covert nature of the network make it ideal for criminal activity and the launch of carefully orchestrated, malicious assaults. Online criminal activity is rampant and getting more intense, according to specialists in cyber security. This chapter has provided a thorough analysis of the various attacks and attack strategies utilized on the dark web. In addition, the authors examine the strengths and weaknesses of the various methods currently in use for threat detection, and how they apply to anonymity networks such as Tor, I2P, and Freenet.

Published: June 2023

The prevailing business methods have a strong focus on environmental sustainability. To that aim, the rising concern about environmental issues in the supply chain has sparked the growth of green supply chains. Organizations are also highly interested in planning and implementing green strategies. In that case, the innovative approach is labeled as the primary driver of change from traditional to green in the supply chain. Therefore, environmental sustainability innovations are examined in this chapter as the forces behind the green supply chain in organizations. 172 waste management and recycling companies are the samples of the study, where path analysis with partial least squares-based structural equation modeling was conducted to test the hypotheses. The findings demonstrate a strong connection between green supply chains and improvements in resource conservation, energy reduction, managing environmental communication, and pollution.

Published: June 2023

In China, the expressways have been built a lot over the past decade. The construction of the expressway suffers from usual cost overrun. There are many factors of different stakeholders influencing the construction cost of expressways, and it is difficult to control all of them. Therefore, it is necessary to identify the key factors causing expressway construction cost overrun and take corresponding cost control measures. In this article, decision-making trial and evaluation laboratory (DEMATEL), interpretative structural modeling method (ISM) and system dynamics (SD) are integrated as DEMATEL-ISM-SD method to identify the key driving factors of expressway construction cost overrun and simulate the interactions of these factors to find the cost control measures. A case in China has been selected as an example to demonstrate how to use the proposed method. As a result, six key factors from different stakeholders are found. Then, six corresponding measures are put forward. This study can provide guidance for expressway construction cost control.

Published: June 2023

Due to emergencies such as GPS failures and hardware malfunctions, the UAVs may need to terminate their flight to prevent further damage. In this work, we propose an emergency landing spot detection algorithm that classifies terrain under the UAVs and identifies an optimal landing spot by safety evaluation. First, a knowledge distillation strategy is introduced for training a real-time semantic segmentation network DDRNet-23-slim with high accuracy. Next, the segmentation map is converted into a binary map and suitable landing areas are identified through morphology operations. Thin operation is then applied to represent the landing areas and the safety score at each point in the skeleton is estimated by the safety degree. Duplicate points are removed using a NMS algorithm, and a list of K points with top safety scores is generated and the optimum spot is then selected from this list. Both segmentation performance and safety gain of the optimum spot have been evaluated in our ZJLabid dataset. Experiment results prove that the proposed algorithm can effectively detect suitable landing spots and achieve a reliable and safe landing.

Published: June 2023

Introduction:

Good communication skills (CSs) are not only the crux of a good doctor–patient relationship but also the foundation over which any human relationship is based. The aim of this study was to assess the impact of training on CS in Phase I MBBS students in a Government Medical College in West Bengal, India.

Materials and Methods:

One hundred and eighty-four Phase I medical students were trained on how to communicate properly with their peers, seniors, teachers, college authorities, department staff, patient relatives, and other health professionals. Each participant underwent a set of three assessments (presession, postsession, and late postsession) for both knowledge and skills in CS. After postsession assessment, feedback by the faculties and peers was provided and reflections were obtained from the participants. A prevalidated questionnaire and Gap-Kalamazoo CS Assessment Form (with some modification) were used for knowledge and skill's assessment, respectively. At the end of the module, feedback was collected from the participants. Data were tabulated and results were compared and interpreted.

Results:

Mean score and standard deviation for knowledge assessment were 5.29 ± 1.35, 9 ± 1.20 and 8.55 ± 0.97 in T1, T2, and T3 and for skills' score were 17.78 ± 4.89, 26.32 ± 5.04 and 30.77 ± 3.66 in SA1, SA2, and SA3, respectively. Most participants showed improvement in T2 with mean improvement score (T2–T1) of 79.57 ± 47.25 and mean retention score (T3–T1) of 71.9 ± 47.84. About 52% of participants showed deterioration in T3 with late deterioration score (T3–T2) of − 4.06 ± 11.42. 33% showed no change in knowledge, i.e., they retained their improvements, whereas 15% showed further improvement. Fifty-two percent of participants showed skills' improvement by scores of 7–12, 43% showed retention by 13–18, and late deterioration was shown by 82%, their scores dropped by 0–6.

Conclusion:

The training module was successfully implemented, and participants appreciated this type of participant centric assessment-based teaching learning module. They learned about the effective ways of communication in a fun manner and were determined to apply all that they have learned.

Authors: Mathew Sherry P. , Rudresh S. A.
Published: June 2023

Introduction:

The primary source of health information for a patient is medical record data. Thus, accurate, complete, and properly recorded patient data are important to provide the best treatment. The workload of the hospital may be reduced and operate more effectively in the hospital if staff members have the necessary knowledge, awareness, and desired clinical abilities, together with an understanding of medical records.

Materials and Methods:

From January 1 to December 31, 2017, the study was carried out at Tertiary Care Hospital Medical Record Department (MRD). The staff was evaluated for their competency and skill gaps using questionnaires. The complete use of the medical records was then evaluated per quarter for a year.

Results:

The staff showed adequate understanding of the various questions about medical records. Over the year, there was the highest utilization of files from the MRD, with medicine and obstetrics and gynecology in broad specialties and the department of cardiology with nephrology having the highest utilization in superspecialties.

Conclusion:

The job environment was pleasant for the staff, and the questionnaire revealed adequate knowledge. Increased satisfaction among MRD staff members, as well as among doctors, nurses, paramedics, and patients, may be related to the utilization being greater in MRD that has been scientifically designed, well-planned, and appropriately structured, with the best physical amenities.
