Background: To investigate, whether 18[18F]-FDG PET/CT - derived radiomics combined with sarcopenia measurements improves survival prognostication among patients with advanced, metastatic gastroesophageal cancer. Methods: In this IRB-approved retrospective study, we included 128 consecutive patients with advanced, metastatic esophageal and gastroesophageal cancer (n=128; 26 females; 102 males; mean age 63.5±11.7 years; age range: 29-91 years) undergoing 18[18F]-FDG PET/CT for staging between November 2008 and December 2019. Segmentation of the primary tumor and radiomics analysis derived from PET and CT images was performed semi-automatically with a commonly used open-source software platform (LIFEX, Version 6.30, lifexsoft.org). Patients’ nutritional status was determined by measuring the skeletal muscle index (SMI) at the level of L3 on the CT component. Univariable and multivariable analyses were performed to establish a survival prediction model including radiomics, clinical data, and SMI score. Results: In a univariable Cox proportional hazards model, ECOG (<0.001) and bone metastasis (p=0,028) were significant clinical parameters for overall survival (OS) and progression free survival (PFS). Age (p=0.017) was an additional prognostic factor for OS. The multivariable analysis revealed improved overall survival prognostication when adding sarcopenic status, PET and CT radiomics to the model with clinical parameters over a clinical course of 6 to 36 months (AUC 0.68 vs. 0.80 at 12 months). Similarly, adding sarcopenia measurements, PET and CT radiomics improved the model fit for PFS (AUC 0.65 vs. 0.82 at 12 months). Conclusion: PET and CT radiomics derived from hybrid 18[18F]-FDG PET/CT combined with sarcopenia measurements and clinical parameters may improve survival prediction among patients with advanced, metastatic gastroesophageal cancer.

Published: August 2022

Background: In our hospital, children with appendicular plastron or abscess receive a medical treatment with cefotaxime, metronidazole and gentamicin followed by amoxicillin/clavulanic acid as an oral switch. Appendectomy is performed 10 to 12 weeks after the beginning of the discharge. A high failure rate was noticed with a switch to a second line treatments, rehospitalization or an emergency surgery. The objective of our study was to highlight predictive factors for the treatment response. Methods: We conducted a retrospective monocentric study between 2009 and 2019. Inclusion criteria were children under 16 years old diagnosed with appendicular plastron or abscess, treated with a medical treatment. We divided the cohort into a success and a failure group and compared their demographic data, clinical symptoms, inflammatory markers, abdominal imaging and antibiotic regimen. Results: Seventy-four patients were enrolled in the study and the failure rate was 36% (n=27). The median age in the success group was 8.7 years old (2-14) and 9.4 years old (2-15) in the failure group. Multiple abscesses (6.5% versus 32%, p=0.02) and diarrhea at admission (19% versus 44%, p=0.02) were significantly associated with a failure. Palpable mass (47% versus 67%, p=0.09) and stercoliths (34% versus 52%, p=0.13) appeared to be more important in the failure group. Discussion and conclusion: Several factors were analyzed to predict the response to the medical treatment for children with appendicular abscess or plastron. Patients with multiple abscesses will no longer be treated with antibiotics. We also recommended greater vigilance after detecting stercoliths in the medical imaging based on other studies results. Time to hospitalization, time to apyrexia, CRP and white blood cells level at admission were not different between the success and the failure group. Finally, a wider bacterial epidemiology study is needed in order to adjust our local guidelines and the antibiotic therapy.

Published: August 2022

Background: COVID-19 Acute Respiratory Distress Syndrome (CARDS) is the major complication of COVID-19. The SARS-CoV-2 outbreaks rapidly saturating ICU beds, forcing the application of non-invasive respiratory support (NIRS) in respiratory intermediate care unit (RICU).Methods: 515 patients were enrolled in our observational prospective study based on CARDS developed in RICU during the three Italian pandemic waves (150, 180 and 185 patients respectively). All selected patients (aged 18-80) were treated with Helmet-Continuous Positive Airway Pressure (H-CPAP). The primary aim of the study is to compare the patients’ clinical characteristics and outcomes (H-CPAP success/failure and survival/death) during the three different pandemic waves. The secondary aim is to evaluate and detect the main predictors of the H-CPAP success and survival/death in patients selected by having CARDS criteria.Results: The worst ratio of arterial partial pressure of oxygen (PaO2) and fraction of inspired oxygen (FiO2) PaO2/FiO2 during H-CPAP stratified the subjects in mild (82-15.9%), moderate (202-39.2%) and severe (231-44.9%) CARDS. H-CPAP success has increased during the three waves (62%, 69% and 77% respectively) and the mortality rate has decreased (28%, 21% and 13%). H-CPAP success/failure and survival/death were related to the ratio PaO2/FiO2 (worst score) in H-CPAP and steroids administration. D-dimer at admission, FiO2 in H-CPAP, and level of PEEP were also associated with H-CPAP success.Conclusions: Our study suggests good clinical outcomes with H-CPAP in CARDS in RICU. CARDS has a biphasic trend confirmed in all the three waves, with a worsening patients’ trend from admission to subsequent days of hospitalization. A widespread use of steroids in our center could play a role in achieving good clinical outcomes. The proper management during hospitalization by pulmonologist in RICU may affect these patients’ trend. We observed a significant improvement of prognosis in the three different waves: patients are found to be progressively slightly less severe.

Authors: Upreti Deepak , Kim Hyunil , Yang Eunmok , Seo Changho
Published: August 2022

The importance of computing and storage capacity has increased over time, and the importance of data mining in industrial engineering has become more apparent. Recently, artificial intelligence and machine learning have made significant advancements in industrial engineering. Federated learning is a machine learning technique that aims to solve the problem of distributed computing systems and their applications of data storage while ensuring data privacy. Tolpegin et al. conducted research on data poisoning attacks in a federated learning system, which we have extended to an analysis of the efficiency of Tolpegin's proposed defense technique. We have subsequently compared the efficiency using uniform manifold approximation and projection (UMAP), principal component analysis (PCA), kernel PCA (KPCA), and K-means clustering algorithms. This study confirms that UMAP performs better than PCA, KPCA, and K-means, and provides excellent performance in mitigating data-poisoning attacks.
Knowledge Flows Within Chinese Administrative Provinces: A Patent Citation Analysis
Authors: Liu Jia , Pénin Julien , Rondé Patrick
Published: August 2022

This paper explores the determinants of knowledge flows, proxied by patent citations, within 31 Chinese administrative provinces. In order to explain the number of citations from a Province to another, in addition to geographic and technological proximity, we use factor analysis to capture the effect of regional research structure. In particular, we measure the private versus public research intensity of each Chinese administrative province. Our econometric results show that, as expected, geographical and technological distance between Provinces are negatively correlated with patent citations. In addition, we find that Chinese administrative provinces that show bigger intensity with regard to public and to private research both receive more patent citations and cite more other patents in other Provinces. This effect is particularly significant when the two regions are specialized in private research. Finally, and at odds with prior research, we find that controlling for social proximity between Provinces does not impact the effect of geographical and technological proximity. These results, if confirmed by further studies, might have significant policy implications.
Efficiency analysis of a four-stroke marine engine
Authors:   Constanta Maritime Univeristy, Stan L. C.
Published: August 2022

Conventional propulsion systems consisting of the main propulsion machine, transmission (axle line) and propeller fail to always meet all the conditions of flexibility, manoeuvrability and space requirements imposed on a modern naval propulsion system. The imposition of new, strict rules in shipbuilding and navigation has led to the emergence of new naval equipment, new propulsion systems that have changed the ship's arrangements for economic and efficiency reasons. The useful volume compared to the total volume of the ship is a good economic indicator that allows the analysis of the income and expenses of construction and operation of the ship. For example, following the analysis of the use of space on board passenger ships built in the last 50 years, the ratio between the volume intended for the propulsion installation and the total volume of the ship varies around an average of 11.3%, (between 8% and 17.5%, exceptionally reaching 22%).
Hollow Structure
Authors:   ”Mircea cel Batran” Naval Academy, Bejan M.
Published: August 2022

Some present requirements of the mechanical structures are high strength and lightweight. A solution is to adopt the hollow structure design. In mechanical engineering industry are commonly using hollow structural sections, surface – type and even three dimensional hollow parts. The final shape is usually the result of structural optimization in which smallest material quantity fulfil the strength requirements. In this paper the study considers a different distribution of the same mass, more exactly starting with a single whole and “splitting” its surface in smaller and smaller holes each iteration. The intuitive expected result in reducing equivalent stresses considering von Mises criteria was not achieved.

Authors:   Ovidius University of Constanța, PINTILIE A.
Published: August 2022

The usual devices for assembling curved naval block sections shall be designed having regard to the regulatory distance of the ship. Even if universal devices are used, they shall be adapted for each cross-section of the ship. In this respect, it is important that the curved surface of the hull is expressed through numerical methods so that the most accurate analytical description of the stand curves required for the construction of the assembly device can be obtained. This work sets out how to calculate and verify the stand data required for the assembly of complex-shaped naval block sections in relation to the outer cover of the vessel.
Contributions to the optimization of air flow in machinery room ventilation systems for special ships
Authors:   ”Mircea cel Batran” Naval Academy, Volintiru O. N.
Published: August 2022

Numerical analyses can demonstrate the poor performance of obsolete ventilation systems and the need to replace or improve them. At the same time, given the destination of the ship that can operate in extreme climates, an efficient ventilation system for machinery rooms is vital. It has been shown in numerous scientific studies that the dispersion and accumulation of gases in the machinery room depends on multiple parameters and under the influence of the temperature gradient and its chemical characteristics, it tends to accumulate in the upper areas of the compartment. Therefore, the flow rate of the ventilation extraction system must be approximately 107 [%] of the flow rate of the air intake system according to the English standard NES 102 [1]. During the study, modelling and simulation were performed with the help of an Engineering Simulation Software to explore and predict how systems will behave in the real world.

Marine ship’s course stabilization based on an autopilot with a simple fuzzy controller
Authors:   Admiral Makarov National University of Shipbuilding, Volyanskyy S.
Published: August 2022

A simple method for generating a fuzzy course controller for a marine ship is presented. The controller is built without using training data. The new fuzzy controller uses conventional triangular sets, no complex overlaps, no complex expert judgments inherent in other types of fuzzy controllers. This approach makes it possible to synthesize a controller based on unified rules. The system is not hybrid and does not use other methods such as neural networks and reference models. The applicability of the proposed approach is demonstrated by an application for controlling the course of a marine ship in various modes. It is shown by means of simulation that the exchange rate stabilization system synthesized with the new fuzzy controller has robust properties.
Analysing the electricity consumers’ attitude with Structural Equation Modeling
Authors:   Bucharest University of Economic Studies, Oprea S.-V.
Published: August 2022

Demand Side Management (DSM) is a set of measures, policies and strategies sensitive to the electricity consumers’ attitude that is a sum of perceptions and expectations influenced by relevant information, related to the benefits that can change the consumers’ behaviour towards sustainable electricity consumption. Internet access, Pro-environmental measures, Expectations and Relation with supplier are several unobserved factors that impact the Attitude of consumers. The Structural Equation Model (SEM) allows us to identify the latent factors and indicate the directional relationships among these factors that are behind the measured items of questionnaire data. Thus, in this paper we propose to analyse a complex data set from a pre-trial questionnaire with SEM and reveal interesting insights related to latent factors that have the potential to enhance the DSM strategies. For simulations, a complex data set with 4,232 observations and 143 items is considered and several smaller data subsets verify whether the model capitalize on change characteristics of a certain data set or not.

Study of the risk assessment quality dependence on the ships accidents analysis
Authors:   Odesa National Maritime University, Melnyk O.
Published: August 2022

Safety is undoubtedly a qualitative basis for the efficient functioning of maritime transport. Particularly important is safety of shipping, freight and passenger transportation. The impetuous growth of ship quantity, increase of their movement along the sea ways as well as the factors of external environment influence underline the necessity to consider the problem of shipping safety as the most priority and actual one in the focus of consideration of the current state and tendencies of the shipping development. As the statistics shows, the main reason of marine accidents are breakdown, damages or failure of engines and equipment. They account for over a third of all recorded cases over the past ten years. The same reason has led in recent years to the most expensive insurance payments, amounting to impressive sums. This explains why risk assessment as a structured process of analysing the consequences and probabilities of dangerous situations is an effective tool for achieving safety goals. The aim of this research is to study the peculiarities of risk assessment process and compare the quality of execution of this process with the accident rate of the world trading fleet. The causes of accident consequences have been systematized, pointing to the fact that seafarers could have prevented most accidents if they had paid proper attention to conducting a risk assessment of the operation, especially the impact of certain elements of the human factor.
The effect of drying temperature on the characteristics of biodegradable plastic from Cassava pulp and Chitosan
Authors: Astuti Adina Widi , Yulianto Agus , Nurbaiti Upik
Published: August 2022

Conventional plastics made from polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC), polystyrene, and poly (ethylene terephthalate) are difficult to decompose. Bioplastics can reduce the amount of toxic waste generated from biological materials other than petroleum.  The combination of cassava pulp and chitosan can be used as a candidate for the manufacture of biodegradable plastics. The optimal drying temperature can produce biodegradable plastics that have good quality. The method used to determine the effect is the mechanical properties test with ASTM D-638M standard and degradation test. The results of this study obtained 6 samples of biodegradable plastic with variations in temperature A=40˚C, B=50˚C, C=60˚C, D=70˚C, E=80˚C and F=90˚C. From the results of the mechanical properties test, the tensile strength values of each sample are A = 0,84 MPa, B = 1,78 MPa, C = 2,24 MPa, D = 1,58 MPa, E = 1,23 MPa and F =0,57 MPa. While the percent elongation value of each sample is A = 11,09%, B = 21,62%, C = 30,25%, D = 15,94%, E = 13% and F = 7,2%. The drying temperature in the process of making biodegradable plastics can affect its mechanical properties, namely the higher the drying temperature used, the lower the tensile strength value and the percent elongation, this is because high temperatures can damage the chemical structure and evaporated sorbitol which serves to increase flexibility. The higher the drying temperature also causes the biodegradable plastic to take longer to degrade. Sample A with the lowest temperature degraded the fastest for 28 days, while sample F with the highest temperature degraded the fastest for 46 days.©2021 JNSMR UIN Walisongo. All rights reserved.

Authors: KOCA Mehmet
Published: August 2022

Cholinesterase (ChE) inhibitors are an important group of drugs used in Alzheimer's, glaucoma, and myasthenia gravis. In recent years, cholinesterase inhibition potentials of compounds have been investigated in new drug discovery studies. In this study (5-formylfuran-2-yl) methyl 4-nitro benzoate (compound 1) and newly designed (5-formylfuran-2-yl) methyl 3,4-dimethoxybenzoate (compound 2) were synthesized. The chemical structures of the synthesized compounds were characterized by spectral data (HRMS, 1H NMR, and 13C NMR). The ChE inhibitory activity of the compounds was evaluated using in vitro colorimetric Ellman method. Compound 1 and compound 2 exhibited inhibitory activity against AChE at IC50 values of 3.25 μM and 8.45 μM, respectively. Compound 1 and Compound 2 showed inhibitory activity against BuChE at IC50 values of 8.45 μM and 14.44 μM, respectively. In Docking simulations with 1EVE and 1P0I, the binding free energy scores of compound 1 were higher than the binding free energy scores of compound 2. In this respect, in silico molecular docking studies overlapped with in vitro enzyme inhibition studies. These derivatives can be used to develop new drugs such as cholinesterase inhibitors.

Published: August 2022

Background

In the master’s program of advanced practice nursing at a Norwegian university college, the learning activity reflection groups were converted into virtual reflection group (VRG) meetings during the COVID-19 pandemic. Regardless of the students’ clinical practices in different hospitals, they could participate in the same VRG meeting on the web together with the educator from the university college, and the clinical supervisors were invited to participate. The students were in the process of developing the core competence required in their role as advanced practice nurses (APNs), and they had increased responsibility in the implementation of the VRG meetings.

Objective

In this study, we aimed to explore how master’s students of advanced practice nursing experienced VRG meetings during the COVID-19 pandemic.

Methods

A qualitative exploratory design was adopted using focus group interviews. A group of students in the master’s program of advanced practice nursing participated in an interview that lasted for 60 minutes. They had experienced participating in the VRG meetings following a rigorous guide during their clinical practice. The data from the focus group were analyzed using qualitative content analysis.

Results

The main findings of this study highlighted the importance of structure in VRG meetings, the role of increased responsibility in students’ learning processes, the development of APN students’ competencies, and increased professional collaboration with clinical supervisors. The APN students and clinical supervisors also continued their discussions in the clinical setting afterward, which strengthened the collaboration between students’ education in the master’s program and their clinical practice.

Conclusions

VRG meetings gave the students the opportunity to lead professional discussions while reflecting thoroughly on the chosen patient cases from clinical practice. They experienced receiving feedback from fellow students, supervisors, and educators as stimulating their critical thinking development.

Following best financial management practices that increase the likelihood of long-term economic sustainability is likely not the primary concern of nonprofit organizations. Nonprofits focus their attention primarily on achieving mission-driven goals. However, research reports that balancing financial sustainability with an organizational mission is a core challenge for most nonprofits, particularly for organizations serving low-income households. This article provides a case study of Farmer Foodshare Inc., a US nonprofit social enterprise in the food sector working with financially challenged family farms, food-insecure households, and low-income elementary school students. This case study was prepared with primary data collected during interviews and secondary sources. In the summer of 2019, the management team of Farmer Foodshare needed to revisit the organization’s operating model. Management in this organization was concerned about whether strategic decisions, such as discontinuing or re-designing some programs, should be made. The case provides firm and industry data to evaluate Farmer Foodshare’s economic sustainability. Enterprise economic sustainability can be assessed by combining an inherent financial analysis with a strategic management analysis. The strategic management analysis, which complements the financial analysis, can be performed with an organizational strategic self-assessment framework by answering questions related to the organization’s mission, results, and plans.

Background: Underwater rugby is a team sport where players try to score points with a negatively buoyant ball while submerged in a swimming pool. Reports of syncope incidents at the Swedish Championships led to us to investigate end-tidal oxygen and carbon dioxide levels during simulated match play. Methods: Eight male underwater rugby club players of varying experience participated. Repetitive measurements were made while players were defending during simulated match play. Each time a player surfaced they exhaled through a mouthpiece connected to a flow meter and a gas analyzer to measure tidal volume, PETO2 and PETCO2. Results: Measurements were made over 12 dives, with an average dive duration of 18.5 seconds. The mean maximal PETCO2 across the eight participants was 10.0 kPa (~75 mmHg) (range, 9.1–11.7 [~68–88]). The corresponding mean minimum PETO2 was 7.6 kPa (~57 mmHg) (6.3–10.4 [~47–78)). PETCO2 drifted upward, with the mean upward change from the first to last dive for each participant being +1.8 (~13.5 mmHg) (SD 1.74) kPa. A similar trend for PETO2 was not detected, with a mean change of -0.1 (~0.75 mmHg) (SD 3.79) kPa. Conclusion: Despite high PETCO2 values that were close to narcotic being recorded, these players seemed to regulate their urge to breathe based on hypoxia rather than hypercapnia.

Divers are regularly exposed to a unique and changing environment that dentists must consider when treating such patients. This review focuses around two case studies encountered in naval dentistry: (i) diving barotrauma (pressure-induced injury related to an air space); and (ii) scuba diving mouthpiece-related oral conditions. Each condition is described by its effect on the oral cavity and in particular the teeth. Then we generally review the latest literature on the different effects of scuba diving on the diver’s head, face and oral regions and emphasize methods of dental disease prevention, diagnostic tools and treatment guidelines.

Carbon monoxide (CO) inhalation is a common method of suicide. The combination of formic acid with sulfuric acid creates carbon monoxide. This novel method is described in readily accessible internet-based resources. We present the case of a 35-year-old woman who developed CO toxicity by using this method. It is important for hyperbaric medicine physicians to be aware of this source of CO toxicity.
Odor Familiarity and Improvement of Olfactory Identification Tests in Chinese Population

Published: August 2022

Aims: This study aimed to design the Chinese Modified Olfactory
Identification (CMOI) test based on the Sniffin’ Sticks Olfactory
Identification (SSOI) test and to present participants’ sensitivity to
unpleasant odors. Materials and methods: We recruited 200 healthy
volunteers from 2021 to 2022; in a survey, 100 volunteers rated their
familiarity with 121 odors, including all the SSOI test odor descriptors
and common odors in Chinese daily life. The SSOI test was modified
according to the survey results. The other 100 were tested three times:
the standard SSOI test, the Modified Distractors Olfactory
Identification(MDOI) test established by modified distractors in the
SSOI test, and the CMOI test developed by using familiar unpleasant
odors to replace the MDOI test odors with low correct recognition rates.
Results: Volunteers were unfamiliar with 31 odor descriptors in the SSOI
test; 23 distractors with low familiarity were replaced with more
familiar distractors. The three odors with the lowest correct
recognition rate in the MDOI test were replaced with familiar unpleasant
odors . The familiarity score was significantly higher in the CMOI test
than in others (P = 8.6864e-13 < 0.0001); the correct
recognition rate in the CMOI test was significantly higher than in the
SSOI test (P = 0.007 < 0.05). Conclusion: The familiarity
scores in the CMOI test were significantly improved; it prevented
choosing wrongly due to unfamiliarity with an odor and its distractors,
highlighting the importance of unpleasant smell with a warning function.
The CMOI test effectively evaluated olfactory function in Chinese
people. Key-words: odor familiarity;olfactory test; modification;

FPGA Realization of an Unsigned Self-Timed 32-Bit Shift-Add Multiplier
Authors: walker alvernon
Published: August 2022

Multiplication and addition determine the performance of general and
special purpose processors because they are fundamental arithmetic
functions. A variety of architectural realizations are needed for these
functions to support the range of tradeoffs required for the board class
of digital applications. A novel 32-bit unsigned shift-add multiplier
Field Programmable Gate Array (FPGA) realization is proposed in this
letter that has a performance-energy dissipation metric sufficiently
different from previously proposed architectures that potentially permit
new applications. The number of clock cycles required to complete the
multiplication equals the number of 0s and 1s substrings in the
multiplier operand. The multiplier is faster than an array multiplier if
the multiplier operand contains less than 10 0s and 1s substrings. It is
fast than the carry-save array multiplier if the number of 0s and 1s
substrings in the multiplier operand is five or fewer. Requires
approximately the same resources as an array multiplier and less than
half the resources required for a carry-save array multiplier.
Public attitudes to population data research in 2022.
Authors: Kashef Shayda , Cowan Mary , Waind Elizabeth
Published: August 2022

ObjectivesBroad public acceptability of research using data and statistics entails demonstrating trustworthiness and understanding public needs to maximise public benefit. Insight into public attitudes is crucial for informing how to operate in a trustworthy way and within the public interest.
ApproachIn 2022, two UK-wide public dialogues were undertaken to explore attitudes regarding the use of data and statistics in research. The first, explored views towards the creation of a more joined-up, efficient and trustworthy national data research infrastructure. The second aimed at understanding public perceptions of ‘public good’ of data and statistics. Both took a deliberative approach and involved diverse participation from members of the UK public. Both also sought the expertise of stakeholders within the data and statistics communities to inform the process.
ResultsThe first dialogue found that the public want:

more proactive transparency around data research processes, with greater efforts made to raise awareness about it and the security processes in place;
meaningful and inclusive public involvement and engagement;
a more standardised, centralised and unified approach to data research across the UK; and
for sensitive data to be made safely and securely available to researchers for projects in the public benefit, regardless of whether those researchers sit within academia, government or the private sector.

The second dialogue launched in March; results will be publicly available by the middle of summer. The findings of this dialogue are intended to influence policy and process relating to the use of data and statistics.
ConclusionThe first dialogue emphasises that the public are supportive of data research. And whilst reassured by security processes, they also do not want them to unduly hinder public benefit. Attendees at the IPDLN Conference will be some of the first to hear about the findings from the second dialogue.
