Protein content and microbial quality of fish sauce in selected provinces of the Philippines
Authors: Peñafiel Christen P. , Escriba Robin P.
Published: July 2023

Fish sauce, a traditional Asian condiment, is derived from the prolonged hydrolysis of salted small fishes, resulting in a mixture of amino acids and proteins. While fermented products are generally considered safe for consumption, ensuring the safety of public consumers remains paramount. Despite this concern, limited research exists in the Philippines on the protein content and microbial quality of fish sauce. Therefore, this study aims to assess the protein content, total halophilic count, and the presence of Salmonella spp. and Staphylococcus aureus in fish sauce produced by unregistered manufacturers in specific provinces of the Philippines. The Kjehldal method was employed to determine the crude protein content, and the organoleptic characteristics, including color, odor, flavor, and aftertaste liking, were evaluated by a panel of 10 sensory experts using a descriptive sensory score sheet. Furthermore, the acceptability of the samples was assessed through a 9-point hedonic scale. The results indicated that the protein content of the five fish sauce samples ranged from 1.00% to 2.06%. According to the required minimum standard set by the Department of Health (DOH) (4.5-2.5%), all fish sauce samples were classified as "fish sauce below standard." Regarding microbiological quality, the Philippines currently lacks standardized limits for fish sauce products. The halophilic count in the samples ranged from 308 to 930 cfu·g-1, while all samples yielded a Staphylococcal count of <10 MPN·g-1 and were negative for Salmonella spp. Furthermore, based on the 9-point hedonic scale, the acceptance score of the five fish sauces was found to be 5.0. This research sheds light on the protein content, microbial safety, and consumer perception of fish sauce produced by unregistered manufacturers in select provinces of the Philippines, emphasizing the need for establishing quality standards to safeguard public health.

The possibilities of using multivariate determination of carbon nanotubes properties based on the dependence data of the normalized transmission logarithm on the sample displacement in the case of Z-scan with an open aperture as well as on the total pulse energy in the case of fixed sample position measurements are studied. The radiation transfer equation for the threshold dependence of the absorption coefficient on the intensity of a flat-top laser beam is used. The data of physical and computational experiments showed the sensitivity of the measured curves with respect to the values of the constants of the optical and threshold energy fluence, as well as the beam waist radius. The possibility of multivariate determination of the properties of liquid carbon nanotube-based dispersed media with a nonlinear optical threshold effect and beam waist radius inside such samples has been established. Keywords: optical limiting, multivariate analysis, carbon nanotubes, Z-scan
Effect of partial substitution of iron for group IV elements on the structure and superconducting properties of the Fe(Se-=SUB=-0.2-=/SUB=-Te-=SUB=-0.8-=/SUB=-)-=SUB=-0.82-=/SUB=- compound
Authors: V.A. Rusakov  , M.P. Volkov
Published: July 2023

The structure and superconducting properties of the Fe1-x(A)x(Se0.2Te0.8)0.82 (x = 0.1, 0.2) compound, where A is Cu, Zn, Bi or Group IV elements (Pb, Sn, Ge), were studied. It was shown that the effect of substitution of some iron atoms on the structure and superconducting properties of the Fe(Se,Te) compound depends on whether a solid solution with a substituting element was formed. If complete dissolution of the replacement element occured (Cu, Zn), then a significant degradation of the superconducting properties was observed. If a separate chalcogenide phase was formed (substitution by Pb, Sn, Ge), then a slight change in the superconducting properties was observed. Such a slight change and even improvement in the superconducting properties upon precipitation of the chalcogenide phase can be associated with both the positive effect of an increase in the relative content of iron and a decrease in the number of iron atoms in the interstitial sites of the β-phase. The preservation of the superconducting properties of the Fe(Se,Te) compound with a small substitution of iron for group IV elements can be used to create wires based on Fe(Se,Te), since impurity chalcogenide particles can act as effective pinning centers. Keywords: Iron-based superconductor, FeSeTe, critical parameters, substitution, structure, electrical resistivity, magnetoresistance, pressure effect.

This study assesses promising field electron sources based on silicon carbide monolithic field emission array (FEA). FEA is fabricated on single-crystal wafers of silicon carbide (0001C) 6H-SiC of n-type conductivity using the technology of two-stage reactive ion etching in SF6/O2/Ar atmosphere. To implement conditions close to breakdown, an experimental setup based on high-voltage narrow pulses generating device GKVI-300 was used. A series of nanosecond voltage pulses with amplitudes from 120 to 250 kV was generated. To study the characteristics of the FEA in the pre-breakdown state, the beam of field emitted electrons was separated from the ion torch or cathode plasma, formed in the following breakdown phases, by placing a 50-μm-thick titanium foil under zero potential into the interelectrode gap. Current-voltage characteristics of peak-currents vs. peak-voltages passing through the foil are close to rectilinear in the Fowler-Nordheim coordinates. The current-voltage characteristics plotted for each of the pulses along increasing and decreasing branches show a discrepancy (hysteresis). After the experiments, the silicon carbide cathode FEA was studied in a scanning electron microscope. Keywords: field electron emission, field emitter array, silicon carbide, pre-breakdown, high-voltage narrow pulses.

Experiments have been carried out to study the influence of the direction of the incoming flow relative to the rotor plane on the values of the drag coefficient of a multi-blade rotor layout with power elements in the form of rotating cylinders of variable cross-section. It is shown that the drag force of the multipath depends on the Reynolds number, and practically remains constant in the range of Reynolds numbers (16-50)· 104 .According to the results of a series of experimental data, the dependences of the thrust coefficient of the multipath rotor on the Reynolds number and the installation angle of the airflow were also calculated and constructed. It is established that the coefficient of thrust of the rotor decreases with an increase in the Reynolds number. Keywords: rotor, Reynolds number, drag force coefficient, thrust force coefficient, WEUC (wind energy utilization coefficient).

Authors: Zhilenko D. Yu.  , Krivonosova O.E.
Published: July 2023

The results of an experimental study of the effects of noises on flows in a rotating spherical layer are presented. Noise is introduced into the flow in the form of random fluctuations of the inner sphere rotational rate relative to a time constant mean value. The flow velocity was measured with a laser Doppler anemometer. It was found that the noises of the equal amplitude, but with different spectra cause the generation of mean flows of different intensity. It is shown that the increase in the average velocities under the action of the noise is larger for the stable flows compared to unstable ones Keywords: noise, flows with rotation, spherical Couette flow.

Plantain cultivation is of great importance for the country´s food security and sovereignty. In Colombia, about 87 % of the established area is associated crop and 13 % as monoculture; It is one of the subsectors that generates the highest income and employment, in 2022 960,000 direct and indirect jobs were reported. In the Caldas department, plantain is cultivated in all municipalities, its value chain, its main actors, flows, synergies, and governance spaces around this productive system were analyzed. For this purpose, a mapping of local actors was used with a Social Network Analysis, a description of the de facto banana value chain and it was analyzed under the Governance Analytical Framework. There is evidence of a productive system with well differentiated areas in terms of technological development, integration of chain links, articulation of institutions, organizational processes, access to national and international markets, and agro-industrial transformation processes. The articulation and cooperation between inter-institutional actors have been critical for development of collective actions to optimize resources, time, processes, and maximize the generated impact. The Caldas roundtables competitiveness emerge and position themselves as a consolidated space for territorial governance, which in turn catalyzes articulation dynamics and institutional interventions to enhance the resources of value chains and territories.

Published: July 2023

Maintaining some productivity of the Creole yam (Dioscorea alata L.), affected by anthracnose (Colletotrichum gloeosporioides), from agrochemicals, generates changes in soil fertility, water quality and in the agricultural ecosystem of peasant agri-food production, but the proportion in which the management of an endemic fungus impacts and therefore persistent over time is unknown. This situation leads to investigate the environmental, economic, and social impact caused by the management of anthracnose in the cultivation of yam in the municipality of Colosó, department of Sucre, Colombia. A descriptive quantitative methodology was followed; A sample of 135 producers participated from techniques such as direct observation, interviews, surveys, focus groups and for the trade-off analysis of environmental, economic and social impacts the Leopold matrix. The results show a peasant production composed mainly of men (96%), of mestizo origin (91.6%), aged 41 to 60 years (55%); level of education in primary (56.5%) and baccalaureate (20.6%); They plant areas of 1.0 to 1.75 hectares (60.1%) and little technical assistance. Soil (47.3%) was impacted by accumulation of agrochemicals and water when contaminated (71.7%). Leopold's matrix considered the transformation of the territory around tutoring, soil loss, contamination of water bodies and burning of crop residues. In conclusion, maintaining the productivity of the Creole yam cultivar involves establishing the trade-off of the relationship between the planned solutions and the impacts on ecosystems in terms of environmental costs.

Authors: McKenna Sarah , Piper Sarah , Capon William , Crowley Alison , Lira Lucas , LaMonica Haley M , Chong Min Kyung , Scott Elizabeth , Hickie Ian , Iorfino Frank
Published: July 2023

Background

Highly personalized care is substantially improved by technology platforms that assess and track patient outcomes. However, evidence regarding how to successfully implement technology in real-world mental health settings is limited.

Objective

This study aimed to naturalistically monitor how a health information technology (HIT) platform was used within 2 real-world mental health service settings to gain practical insights into how HIT can be implemented and sustained to improve mental health service delivery.

Methods

An HIT (The Innowell Platform) was naturally implemented in 2 youth mental health services in Sydney, Australia. Web-based surveys (n=19) and implementation logs were used to investigate staff attitudes toward technology before and after implementation. Descriptive statistics were used to track staff attitudes over time, whereas qualitative thematic analysis was used to explore implementation log data to gain practical insights into useful implementation strategies in real-world settings.

Results

After the implementation, the staff were nearly 3 times more likely to agree that the HIT would improve care for their clients (3/12, 25% agreed before the implementation compared with 7/10, 70% after the implementation). Despite this, there was also an increase in the number of staff who disagreed that the HIT would improve care (from 1/12, 8% to 2/10, 20%). There was also decreased uncertainty (from 6/12, 50% to 3/10, 30%) about the willingness of the service to implement the technology for its intended purpose, with similar increases in the number of staff who agreed and disagreed with this statement. Staff were more likely to be uncertain about whether colleagues in my service are receptive to changes in clinical processes (not sure rose from 5/12, 42% to 7/10, 70%). They were also more likely to report that their service already provides the best mental health care (agreement rose from 7/12, 58% to 8/10, 80%). After the implementation, a greater proportion of participants reported that the HIT enabled shared or collaborative decision-making with young people (2/10, 20%, compared with 1/12, 8%), enabled clients to proactively work on their mental health care through digital technologies (3/10, 30%, compared with 2/12, 16%), and improved their response to suicidal risk (4/10, 40% compared with 3/12, 25%).

Conclusions

This study raises important questions about why clinicians, who have the same training and support in using technology, develop more polarized opinions on its usefulness after implementation. It seems that the uptake of HIT is heavily influenced by a clinician’s underlying beliefs and attitudes toward clinical practice in general as well as the role of technology, rather than their knowledge or the ease of use of the HIT in question.
Effects of Web-Based Mindfulness-Based Interventions on Anxiety, Depression, and Stress Among Frontline Health Care Workers During the COVID-19 Pandemic: Systematic Review and Meta-Analysis

Published: July 2023

Background

Since 2019, the COVID-19 outbreak has spread around the world, and health care workers, as frontline workers, have faced tremendous psychological stress.

Objective

The purpose of this study is to explore whether web-based mindfulness-based interventions continue to have a positive impact on anxiety, depression, and stress among health care workers during the COVID-19 pandemic.

Methods

The inclusion criteria were as follows: (1) participants were frontline health care workers during the COVID-19 pandemic; (2) the experimental group was a web-based mindfulness-based intervention; (3) the control group used either general psychological intervention or no intervention; (4) outcome indicators included scales to assess anxiety, depression, and stress; and (5) the study type was a randomized controlled study. Studies that did not meet the above requirements were excluded. We searched 9 databases, including Web of Science, Embase, PubMed, Cochrane Library, Scopus, ScienceDirect, SinoMed, China National Knowledge Infrastructure (CNKI), and Wanfang Database, for randomized controlled studies on the effects of web-based mindfulness-based interventions on common mental disorder symptoms among health care workers from January 1, 2020, to October 20, 2022. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database scale. The Cochrane risk of bias tool was used to assess the risk of bias. Subgroup analysis was used to look for sources of heterogeneity and to explore whether the results were the same for subgroups under different conditions. Sensitivity analysis was used to verify the stability of the pooled results.

Results

A total of 10 randomized controlled studies with 1311 participants were included. The results showed that web-based mindfulness-based interventions were effective in reducing the symptoms of anxiety (standard mean difference [SMD]=–0.63, 95% CI –0.96 to –0.31, P<.001, I2=87%), depression (SMD=–0.52, 95% CI –0.77 to –0.26, P<.001, I2=75%), and stress (SMD=–0.20, 95% CI –0.35 to –0.05, P=.01, I2=58%) among health care workers during the COVID-19 pandemic, but with wide CIs and high heterogeneity.

Conclusions

Web-based mindfulness-based interventions may be effective in reducing the symptoms of anxiety, depression, and stress among frontline health care workers during the COVID-19 pandemic. However, this effect is relatively mild and needs to be further explored by better studies in the future.

Adult Patients’ Experiences of Using a Patient Portal With a Focus on Perceived Benefits and Difficulties, and Perceptions on Privacy and Security: Qualitative Descriptive Study
Authors: Son Elisa H , Nahm Eun-Shim
Published: July 2023

Background

Patient portals can facilitate patient engagement in care management. Driven by national efforts over the past decade, patient portals are being implemented by hospitals and clinics nationwide. Continuous evaluation of patient portals and reflection of feedback from end users across care settings are needed to make patient portals more user-centered after the implementation.

Objective

The aim of this study was to investigate the lived experience of using a patient portal in adult patients recruited from a variety of care settings, focusing on their perceived benefits and difficulties of using the patient portal, and trust and concerns about privacy and security.

Methods

This qualitative descriptive study was part of a cross-sectional digital survey research to examine the comprehensive experience of using a patient portal in adult patients recruited from 20 care settings from hospitals and clinics of a large integrated health care system in the mid-Atlantic area of the United States. Those who had used a patient portal offered by the health care system in the past 12 months were eligible to participate in the survey. Data collected from 734 patients were subjected to descriptive statistics and content analysis.

Results

The majority of the participants were female and non-Hispanic White with a mean age of 53.1 (SD 15.34) years. Content analysis of 1589 qualitative comments identified 22 themes across 4 topics: beneficial aspects (6 themes) and difficulties (7 themes) in using the patient portal; trust (5 themes) and concerns (4 themes) about privacy and security of the patient portal. Most of the participants perceived the patient portal functions as beneficial for communicating with health care teams and monitoring health status and care activities. At the same time, about a quarter of them shared difficulties they experienced while using those functions, including not getting eMessage responses timely and difficulty finding information in the portal. Protected log-in process and trust in health care providers were the most mentioned reasons for trusting privacy and security of the patient portal. The most mentioned reason for concerns about privacy and security was the risk of data breaches such as hacking attacks and identity theft.

Conclusions

This study provides an empirical understanding of the lived experience of using a patient portal in adult patient users across care settings with a focus on the beneficial aspects and difficulties in using the patient portal, and trust and concerns about privacy and security. Our study findings can serve as a valuable reference for health care institutions and software companies to implement more user-centered, secure, and private patient portals. Future studies may consider targeting other patient portal programs and patients with infrequent or nonuse of patient portals.

Participatory surveillance (PS) has been defined as the bidirectional process of transmitting and receiving data for action by directly engaging the target population. Often represented as self-reported symptoms directly from the public, PS can provide evidence of an emerging disease or concentration of symptoms in certain areas, potentially identifying signs of an early outbreak. The construction of sets of symptoms to represent various disease syndromes provides a mechanism for the early detection of multiple health threats. Global Flu View (GFV) is the first-ever system that merges influenza-like illness (ILI) data from more than 8 countries plus 1 region (Hong Kong) on 4 continents for global monitoring of this annual health threat. GFV provides a digital ecosystem for spatial and temporal visualization of syndromic aggregates compatible with ILI from the various systems currently participating in GFV in near real time, updated weekly. In 2018, the first prototype of a digital platform to combine data from several ILI PS programs was created. At that time, the priority was to have a digital environment that brought together different programs through an application program interface, providing a real time map of syndromic trends that could demonstrate where and when ILI was spreading in various regions of the globe. After 2 years running as an experimental model and incorporating feedback from partner programs, GFV was restructured to empower the community of public health practitioners, data scientists, and researchers by providing an open data channel among these contributors for sharing experiences across the network. GFV was redesigned to serve not only as a data hub but also as a dynamic knowledge network around participatory ILI surveillance by providing knowledge exchange among programs. Connectivity between existing PS systems enables a network of cooperation and collaboration with great potential for continuous public health impact. The exchange of knowledge within this network is not limited only to health professionals and researchers but also provides an opportunity for the general public to have an active voice in the collective construction of health settings. The focus on preparing the next generation of epidemiologists will be of great importance to scale innovative approaches like PS. GFV provides a useful example of the value of globally integrated PS data to help reduce the risks and damages of the next pandemic.

Authors: Zhang Dong-Dong , Lei Min , Wang Yue , Zeng Pei-Ji , Hong Yong-Jun , Cai Cheng-Fu
Published: July 2023

Background

The incidence of oropharyngeal squamous cell carcinomas (OPSCC) has increased in recent decades, and human papillomavirus (HPV) infection is the main cause of OPSCC. The data regarding causes of death (CODs) are vitally important in informing follow-up strategies and revising treatment strategies to deal with any possible preventable treatment-related COD. However, limited studies have assessed the competing COD by HPV status in patients with OPSCC.

Objective

We aimed to analyze the distribution of the competing COD according to HPV status in OPSCC.

Methods

We retrospectively included stage I-IVB patients with OPSCC from the Surveillance, Epidemiology, and End Results database between 2010 and 2015. The association between HPV status and head and neck cancer–specific mortality (HNCSM), second primary cancer mortality (SPCM), and noncancer-caused mortality (NCCM) were analyzed. The chi-square test, Kaplan-Meier analysis, and Fine and Gray model were used for statistical analysis.

Results

We included 5852 patients in this study and 73.2% (n=4283) of them had HPV-related tumors. A total of 1537 (26.3%) patients died, including 789 (51.3%), 333 (21.7%), and 415 (27%) patients who died from head and neck cancer, second cancer, and noncancer causes, respectively. The 5-year HNCSM, SPCM, NCCM, and overall mortality were 14.7%, 6.5%, 7.7%, and 26.4%, respectively. Those with HPV-positive disease had a lower cumulative incidence of HNCSM (subdistribution hazard ratio [sHR] 0.362, 95% CI 0.315-0.417; P<.001), SPCM (sHR 0.400, 95% CI 0.321-0.496; P<.001), and NCCM (sHR 0.460, 95% CI 0.378-0.560; P<.001) than those with HPV-negative disease. The 5-year risk of HNCSM was 26.9% and 10.7% in those with HPV-negative and HPV-positive disease, respectively (P<.001). The 5-year risk of SPCM was 12.4% and 4.6% in those with HPV-negative and HPV-positive disease, respectively (P<.001). The 5-year risk of NCCM of death was 13.7% and 5.8% in those with HPV-negative and HPV-positive disease, respectively (P<.001). Using the Fine and Gray competing-risks model, our results show that those with HPV-negative tumors had a significantly higher risk of HNCSM (P<.001), SPCM (P<.001), and NCCM (P<.001) than those with HPV-negative tumors.

Conclusions

HPV-positive OPSCC has a lower NCSM, SPCM, and NCCM as compared to those with HPV-negative OPSCC. HPV positivity is a favorable prognostic factor in the context of overcoming cancer as well as in terms of reducing the risk of other CODs in OPSCC. Our finding supports the need to tailor patient follow-up based on the HPV status of patients with OPSCC.
Guideline-Adherent Physiotherapy for Patients With Hip and Knee Osteoarthritis in Germany: Protocol for an Implementation Research Project Using the Theoretical Domains Framework and the Behavior Change Wheel
Authors: Bahns Carolin , Scheffler Bettina , Kopkow Christian
Published: July 2023

Background

Hip and knee osteoarthritis is common and leads to pain, stiffness, and disability. Clinical practice guidelines provide recommendations based on the best available evidence to assist health care professionals and patients in clinical decision-making. However, several studies have reported a gap between guideline recommendations and clinical practice in physiotherapy. Improved implementation strategies and the removal of existing barriers may facilitate the transfer of evidence into clinical practice and contribute to optimized quality of care.

Objective

This paper presents the protocol for a study that aims to describe the current physiotherapy practice in patients with hip and knee osteoarthritis and to investigate physiotherapists’ adherence to clinical practice guidelines, to identify and specify barriers to and facilitators of guideline use and implementation, and to develop and pilot test a theory-based tailored implementation intervention aiming to increase guideline use in osteoarthritis care.

Methods

The research project is divided into 4 parts. During the first part, we will conduct a nationwide web-based survey among German physiotherapists to evaluate the current management of hip and knee osteoarthritis and to evaluate whether treatment aligns with guideline recommendations. Subsequently, semistructured interviews will be conducted to specify barriers to and facilitators of guideline use and implementation among physiotherapists (part 2). On the basis of these findings, in part 3, we will develop a theory-driven implementation intervention based on the Theoretical Domains Framework and the Behavior Change Wheel, which will be evaluated in a controlled pilot study in terms of effectiveness, feasibility, and acceptability (part 4).

Results

Data collection of the web-based survey among German physiotherapists (part 1) was completed in December 2021. The semistructured interviews (part 2) were conducted between January and September 2023. Recruitment of physiotherapy practices to participate in the development of the implementation intervention is expected to start in January 2024.

Conclusions

This research project aims to develop a theory-driven implementation intervention to facilitate the transfer of evidence from hip and knee osteoarthritis guidelines in physiotherapy practice. We hypothesize that successful implementation will lead to increased guideline adherence in physiotherapists, which in turn will improve the quality of care. The results from our project will provide valuable knowledge concerning the development process and effectiveness of tailored implementation interventions.

Trends in Cause-Specific Injury Mortality in China in 2005-2019: Longitudinal Observational Study
Authors: Ji Zixiang , Wu Hengjing , Zhu Rongyu , Wang Lu , Wang Yuzhu , Zhang Lijuan
Published: July 2023

Background

Over the last few decades, although the age-standardized mortality rate (ASMR) of injury has shown a significant declining trend in China, this pattern has dramatically reversed recently.

Objective

We aimed to elucidate the geographical, demographic, and temporal trends of cause-specific injuries, the reversal phenomenon of these trends, and the fluctuations of injury burden from 2005 to 2019 in China.

Methods

A longitudinal observational study was performed using the raw data of injury deaths in the National Cause-of-Death surveillance data provided by the disease surveillance points system in 2005-2019. The cause-specific injuries were divided into disparate subgroups by sex, age, urban/rural region, and eastern/central/western areas of China. The burden of injury was assessed using potential years of life lost (PYLL), average years of life lost (AYLL), and PYLL rate (PYLLR). Temporal trends of mortality rates and burden were evaluated using best-fitting joinpoint models.

Results

Injury deaths accounted for 7.51% (1,156,504/15,403,835) of all-cause deaths in China in 2005-2019. The crude mortality rate of all-cause injury was 47.74 per 100,000 persons. The top 3 injury types (traffic accident, falls, and suicide) accounted for 70.57% (816,145/1,156,504) of all injury-related deaths. The ASMR of all-cause injury decreased (P=.003), while the crude mortality rate remained unchanged (P=.52) during 2005-2019. A significant reverse trend in ASMR of all-cause injury was observed in urban older adults since 2013, mainly due to the inverted trend in injuries from falls. A reverse trend in ASMR of suicide was observed among individuals aged 10-24 years, with notable increases by 35.18% (annual percentage change 15.4%, 95% CI 4.1%-28.0%) in men since 2017. The AYLL and PYLLR of all-cause injury among older adults showed consistent ascending trends from 2005 to 2019 (average annual percentage change [AAPC] 6.1%, 95% CI 5.4%-6.9%, 129.04% increase for AYLL; AAPC 5.4%, 95% CI 2.4%-8.4%, 105.52% increase for PYLLR). The AYLL due to suicide for individuals aged 10-24 years showed a considerable upswing tendency (AAPC 0.5%, 95% CI 0.4%-0.7%, 8.02% increase).

Conclusions

Although the ASMR of all-cause injury decreased in China from 2005 to 2019, the trend in suicide among adolescents and young adults and falls among older adults has been on the rise in recent years. Interventions should be encouraged to mitigate the cause-specific burdens of injury death.

Published: July 2023

Football is one of the most popular sports in the world. The popularity makes every topic related to football interesting, for instance, the FIFA World Cup winner prediction. This topic is not only for casual discussion but could be a practical decision support for coaching staff to rate the team’s readiness. Most prediction methods use large match datasets. Since every national team has a different squad for every world cup and the FIFA World Cup is held every four years, the usage of a large match dataset is irrelevant. Therefore, there is a need for a prediction method based on the relevant data. We applied the Poisson distribution model for predicting the FIFA World Cup 2022 knockout stage match results. We calculate the probability of winning and losing based on their average goal scores and goal conceded and evaluate the difference by the actual result using de Finetti distance. The successful prediction is 8 out of 15 matches, with six inside the round of 16 games. Thus, the new data attributes need to reformulate Poisson’s lambda. Further studies need to add the 3-4 prior world cup matches data to increase the acceptance of prediction.

The basic thing to consider when building a quadruped robot is the issue of balance. These factors greatly determine the success of the quadruped robot in carrying out movements such as stabilizing the body on an inclined plane, walking movements and others. Conventional feedback control methods by performing mathematical modeling can be used to balance the robot. However, this method still has weaknesses. The application of conventional feedback control methods often results in an inaccurate controller, so it must be manually tuned for its application. In this study, reinforcement learning methods were used using Q-Learning algorithms. The use of reinforcement learning methods was chosen because no mathematical calculations are needed to control the balance of quadruped robots. The process of learning the system to train the agent's abilities is carried out using a Gazebo simulator. The learning results show that the system could run well as evidenced by the higher value of sum rewards per episode.

Gamelan consists of various kinds of instruments that have different characteristics. Each has characteristics in terms of the basic frequency, amplitude, signal envelope, and different ways of playing it, resulting in differences in the sustain power of the signal. These characteristics cause the problem of vanishing gradient in the Elman Network model which was used in previous studies in studying the onset detection in the Saron instrument signal which has an average interval of more than 0.6 seconds. This study uses BLSTM (Bidirectional Long Short Term Memory) as a model for training and Wavelet Packet Transformation to design a psychoacoustic critical bandwidth as a model for feature extraction. For the peak picking method, this study uses a fixed threshold method with a value of 0.25. The use of the BLSTM model supported by the Wavelet Packet Transform is expected to overcome the vanishing gradient that exists in a simple RNN architecture. The model was tested based on 3 evaluation parameters, namely precision, recall and F-Measure. Based on the test scenario carried out, the model can overcome the vanishing gradient problem on the Saron instrument which has an average interval between onset of 600 ms. Out of a total of 428 onsets on the Saron instrument, the model successfully detected 426 correctly, with 4 incorrectly detected onsets and 2 undetected onsets. A thorough evaluation for each of the precision, recall, and F1-Measure algorithms obtained 0.975, 0.945 and 0.960.

Insufficient use of fertilizers results in non-optimal plant growth, while excessive use is wasteful and results in pollution. Sensor usage is one method for measuring the nutrient content in the soil so that the fertilization process can be carried out precisely. Accuracy, precision, and error are commonly used in analyzing sensor quality. But for chemical measurements, the specificity also needs to be analyzed. This is because the soil contains various types of nutrients, so it is necessary to know whether the readings from the sensor only come from the desired nutrients or the others. In this writing, the elements measured were N, P, and K which are nutrients needed by plants in large quantities. The sensors were tested using compounds containing N, P, or/and K elements and NPK fertilizers with different NPK ratios. Results of this study prove that the sensor is not specific as the readings are known to use the electroconductivity method as proved by the regression results between the two variables which have R² ≈ 1 correlation. In addition, the sensor also produces readings for elements/compounds that should not be read and cannot distinguish the ratio of types of compound NPK fertilizer with different types.

Authors: Wang Jacqueline
Published: July 2023

The Covid-19 pandemic has once again caused citizens around the world to attach importance to the urgency of the waste management crisis and the need for environmental action in general, and this should act as a wake-up call for taking the boundary between human consumption of non-sustainable activities and the capacity of the natural environment seriously. Governments in the Netherlands and Japan designed and implemented policies to facilitate the transition to a circular economy and to promote sustainable waste management. This paper reviews waste management policies and practices in the two countries, explores a circular economy strategy based on coastal cities, using examples of different zero waste cities to examine how coastal cities have adapted to the zero waste masterplan.

El objetivo de este trabajo es analizar el grado de alfabetización de los adolescentes de la provincia de Pontevedra (Galicia-España) sobre la biodiversidad local, a través del estudio del influjo de las variables: ocio en contacto con la naturaleza, lugar de residencia, valores familiares, género y edad. A partir de un muestreo por cuotas cruzadas se aplicó un cuestionario elaborado ad hoc y se obtuvieron 683 casos válidos. Para el análisis de los datos se usaron pruebas no paramétricas y se realizó un análisis descriptivo. Se constata que el conocimiento de los adolescentes es limitado, que aquéllos que tienen más ocio en la naturaleza y habitan en zonas rurales identifican más especies y que la familia influye en este conocimiento. En síntesis, se enfatiza la importancia de educar y promover experiencias de ocio en la naturaleza para aumentar el conocimiento sobre la biodiversidad local, valorarla y protegerla.
El aprendizaje con cuentos y manuales en la infancia
Authors: Mareovich Florencia , Peralta Olga Alicia
Published: July 2023

Este trabajo compara el aprendizaje acerca del mundo natural (animales) y del mundo artificial (medios de transporte) utilizando libros de cuentos antropomórficos y manuales realistas. Los niños y niñas realizaron individualmente un pretest consistente en ubicar medios de transporte o animales poco convencionales en sus respectivos escenarios (acuático, aéreo, terrestre). A lo largo de seis sesiones grupales en el aula, una investigadora enseñó acerca del mundo natural y artificial utilizando cuentos o manuales con animales y medios de transporte. Finalmente, los niños y niñas realizaron un postest igual al pretest. Se encontró que la ejecución mejoró entre pre y postest, tanto al utilizar cuentos como al utilizar manuales, pero significativamente sólo con cuentos. La comparación entre condiciones en el postest mostró diferencias significativas en el aprendizaje sobre el mundo natural a favor de los cuentos. Los resultados indican que los cuentos serían un mejor medio de aprendizaje para los preescolares.

Authors: Moreles Vázquez Jaime
Published: July 2023

A partir de las premisas de los estudios del uso de la investigación, y mediante el análisis documental, el objetivo del presente trabajo consistió en investigar cómo se utiliza y cómo se puede mejorar el uso de la investigación en la nueva política migratoria mexicana. El estudio fue cualitativo y se dividió en dos etapas: en la primera fase los resultados muestran que, aunque hay mucha investigación sobre migración internacional, y que ésta puede emplearse de diversas formas, en ese documento solamente se citan algunas referencias y se utilizan para definir el problema y destacar su importancia. En la segunda etapa se proponen usos más elaborados de la investigación que incluyen la identificación de factores clave y de potenciales alternativas. Además de contribuir a una mejor comprensión del desafío, el trabajo muestra que enriquecer la política desde la investigación podría orientar otros programas públicos y, eventualmente, prácticas específicas.

Abstract: In this paper, we are going to overview a newvariant of the classical assignment problem referred to as the cyclic bottleneck assignment problem (CBAP). This problem can arise in the healthcare industry or supply chain management. The problem can arise in surgical room scheduling and can be described as follows. Each of m successive time units can be allocated to any of the m surgeonsavailable. The number of patients to be scheduled for surgery on a given unit and the length of stay of the patient in the recovery unit are dependent on the type of surgery. The problem is to assign one surgeon to each OR time so as to minimize the maximum number of patients that will be expected to occupy the recovery unit in the long run. In this paper we have compared various ways through which the CBAP has been solved , that is Cohort Intelligence[4] , Tabu Search[2] and Iterated Local Search

Abstract: In recent years, there has been a lot of research done on encrypted search technologies. Creating indexes with separate keywords has led to high storage costs and poor search accuracy, which has made the issue urgently need to be solved as more and more data is being stored in the cloud. So, for encrypted cloud data, we provide a novel feature matching ranked search method (FMRSM) in this study. This approach builds indexes using the feature score algorithm (FSA), which enables multiple keywords to be mapped to an index dimension after being taken from a page as a feature. As a result, index storage costs may be decreased and encryption effectiveness can be increased. Furthermore, the FMRSM generates trapdoor processes using a matching score algorithm (MSA). The matching score algorithm is able to produce results with improved ranking accuracy because to FSA, which allows it to rank the search results according to the type of match and the amount of matching terms. A thorough investigation shows that our mechanism is more practical and efficient
Designing Intuitive and Effective Dynamic Facial Authentication: Machine Interaction with Human Factors

Published: July 2023

Abstract: The objective of this paper is to propose a spoof-free Face Liveness Detection system with an active approach that uses the challenge-response methodology which detects the motions and gestures of the user, thereby analyzing and recognizing a real face from a photo. With cybercrimes on the rise each day, identity thefts being one of them- especially in an unsupervised authentication system, has given rise to serious security concerns. Face liveness detection assures the user's actual presence and validates their identities. Along with that, it prevents fraudulent reproduction of face biometrics to spoof the system and thus effectively protects the rights and data of the legitimate user. A review of the many scholarly pieces of the literature revealed works of some of the existing systems that use active or passive techniques to test liveness though there is still a need for a more robust approach. Predicted results of the Human-Computer Interaction (HCI) based approach demonstrated high accuracy in detecting the liveness of the user which effectively reduced system vulnerability to face-spoof attacks. The aim is to create a system that is highly accurate, efficient, and can be integrated with existing systems.
