Defining food literacy and dietary patterns among senior high school students in Malang City, East Java

Background: Food literacy is a collection of interrelated knowledge, skills, and behavior required to plan, manage, select, prepare, and eat food for further meeting dietary requirements and determining dietary intake. In Indonesia, 93.6% of all adolescents aged 10 years or over consumed an inadequate amount of fruits and vegetables and more than half often consumed food rich in sugar, fat and salt. Only one-third of students always had breakfast, only 3,81% always brought their own food to school. Adolescence has been considered as a nutritionally critical period of life. Improve the health promotion is important to prevent malnutrition and risk of chronic disease.Objectives: The study aimed to investigate the association of food literacy and dietary patterns among senior high school students in Malang, East Java.Materials and Methods: The cross-sectional study determined food literacy level and dietary patterns among senior high school students using a questionnaire as the instrument. This study recruited 464 students aged from 14 to 18 years old. Demographic characteristics of adolescents and their parents, adolescent food literacy, and dietary intake data were self-report collected. The height was measured using stature meter and weight using electronic scale to determine the BMI-for-age. The research was conducted from July to September 2015 in Malang, East Java.Results: Out of 464 adolescents, 59.9% were females, and female adolescents had a better food literacy (P < .001) and higher dietary pattern scores (P < .05). Adolescents whose family had higher income or higher percentage of income spent on food consumed more vegetables (P < .05) and dairy products (P < .05), and had higher dietary pattern scores (P < .05) compared with those whose family had lower income or lower percentage of income spent on food. The perception of food literacy (r = 0.187, P < .001), the behavior of food literacy (r = 0.333, P < .001), and overall food literacy (r = 0.329, P < .001) were positively correlated with dietary pattern scores.Conclusions: Food literacy is positively associated with dietary patterns in adolescents. Nutrition education is suggested to implement as a guide in healthy food choices for adolescent.
Evaluating the Effect of Parkinson's Disease on Jitter and Shimmer Speech Features

Background: Parkinson's disease (PD) is a neurological disorder caused by decreasing dopamine in the brain. Speech is one of the first functions that are disrupted. Accordingly, speech features are a promising indicator in PD diagnosis for telemedicine applications. The purpose of this study is to investigate the impact of Parkinson's disease on a minimal set of Jitter and Shimmer voice indicators and studying the difference between male and female speech features in noisy/noiseless environments. Materials and Methods: Our data includes 47 samples from nursing homes and neurology clinics, with 23 patients and 24 healthy individuals. The optimal feature for each category is studied separately for the men's and women's samples. The focus here is on the phonation in which the vowel/a/is expressed by the participants. The main features, including Jitter and Shimmer perturbations, are extracted. To find an optimal pair under both noisy and noiseless circumstance, we use the Relief feature selection strategy. Results: This research shows that the Jitter feature for men and women with Parkinson's is 21 and 33.4, respectively. While the Shimmer feature is 0.1 and 0.06. In addition, by using these two features alone, we reach a correct diagnosis rate of 79% and 81% for noisy and noiseless states, respectively. Conclusion: The PD effects on the speech features can be accurately identified. Evaluating the extracted features suggests that the absolute value of the selected feature in men with PD is higher than for healthy ones. Whereas, in the case of women, this is the opposite.
Sex-Related Factors in Cardiovascular Complications Associated to COVID-19

Coronavirus disease 2019 (COVID-19), the pandemic infection caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), presents with an extremely heterogeneous spectrum of symptoms and signs. The clinical manifestations seem to be correlated with disease severity. COVID-19 susceptibility and mortality show a significant sex imbalance, with men being more prone to infection and showing a higher rate of hospitalization and mortality compared to women. Such variability can be ascribed to both sex-related biological factors and gender-related behavioral cues. This review will discuss the potential mechanisms accounting for sex/gender influence in vulnerability to COVID-19. Cardiovascular diseases play a central role in determining COVID-19 outcome, whether they are pre-existent or arose upon infection. We will pay particular attention to the impact of sex and gender on cardiovascular manifestations related to COVID-19. Finally, we will discuss the sex-dependent variability in some biomarkers for the evaluation of COVID-19 infection and prognosis. The aim of this work is to highlight the significance of gendered medicine in setting up personalized programs for COVID-19 prevention, clinical evaluation and treatment.
The Impact of Student’s Anxiety on u sing Learning Management Systems in Covid 19 Pandemic

The COVID-19 pandemic has compelled many educational institutions worldwide to use learning management systems (LMS) to deliver their courses. This study aims to determine the constituents that affect scholars when using LMS for graduation during the pandemic. This research also examines the impact of the students' anxiety level when using the LMS by conducting multiple group analyses with the partial least square's method. The results show a significant influence on the students' anxiety level when using the LMS. Students who have a low level of anxiety exhibited insignificant communication quality regarding the perceived ease of use and perceived usefulness. Meanwhile, students with a high level of anxiety highlight a consequential effect of communication quality in the perceived ease of use and usefulness. Moreover, students with a low level of anxiety displayed significantly high-perceived usefulness, satisfaction, and subject norm when using the LMS. In contrast, students with a high level of anxiety did not display perceived usefulness, satisfaction, or subject norm when using the LMS. As a result of the findings from this research, concrete effects can be provided for educationalists, policymakers, and practitioners, who want to advance functional procedures to enhance the design of the LMS during COVID-19.
Astudy of the applicability to the fatigue of concrete of the Palmgren-Miner partial damage hypothesis

Synopsis This investigation provides some information concerning the applicability to the fatigue of concrete of the Palmgren-Miner partial damage hypothesis. The results do not contradict this hypothesis. The tests were performed on small concrete cylinders at high load-alternation frequencies. A Wohler curve plotted for the concrete cylinders shows that fatigue in these occurs in the same way as in large specimens subjected to lower load-alternation frequencies. Fatigue of concrete due to non-alternating variable load pulses can be calculated from an expression relating to the Wohler curve for concrete, combined with the Palmgren-Miner partial damage hypothesis.
Critical review of mercury methylation and methylmercury demethylation rate constants in aquatic sediments for biogeochemical modeling

Abstract Mercury is a toxin that causes neurological impairments in adults, is particularly harmful for fetuses and children, and is deadly in severe cases, making it a worldwide health concern. Methylmercury (MeHg) is the environmentally relevant form of mercury (Hg) because it biomagnifies along the food chain. Methylmercury is mainly produced in aquatic sediments via methylation of inorganic Hg (Hg(II)) and transformed back via demethylation. Because transformation rates determine MeHg concentrations, quantification of methylation and demethylation rates is needed to inform management of MeHg. Published rate constants for Hg(II) methylation ( ) and MeHg demethylation ( ) vary greatly, stemming partly from differences in experimental methods. We conducted a comprehensive review of rate laws, evaluated published rate constants, and performed biogeochemical simulations to assess variability in reported and Based on selected studies employing the same pseudo-first-order rate law and similar experimental methods, we found that is a reasonable range for wetland sediments. Over a number of environments, maximum was smaller at sites without Hg source ( ) than at sites with identified Hg source ( ). Larger variability and higher uncertainty in compared to highlight the need for more research on MeHg demethylation rates. This critical review: (a) aids the design of future experimental studies of and (b) provides guidance for comparing rate constants from different studies; (c) presents a biogeochemical reaction model to assess rate constants; and (d) informs selection of and values from the literature for use in model simulations.

Modeling and Comparison of Bimorph Power Harvesters with Piezoelectric Elements Connected in Parallel and Series

Power harvesting devices are designed to convert the ambient energy surrounding a system to usable electric energy. The strong desire to create self-powered systems, which do not rely on traditional energy sources such as electrochemical batteries has led to the rapid growth of this field. One type of energy harvesting is the use of piezoelectric materials to directly transform ambient vibration to electrical energy. In the majority of applications the piezoelectric is configured as a bimorph bender, where the two patches of piezoceramic material can be electrically connected in either series or parallel. A reduced model will be used here to develop a set of closed form solutions to the power harvesting performance of the system based on the electrical connection of the piezoelectrics. It will be theoretically and experimentally shown that the maximum power output and efficiency is independent of the electrical connection. However, the voltage (and current) outputs between a series and parallel conditions are related by a factor of two with a symmetric system. Additionally, a critical impedance will be derived to serve as a criterion on selecting the appropriate electrical connection between the piezoelectrics to tune the systems performance based on the impedance of external circuitry.

ECO-LABELING AND INTERNATIONAL TRADE AGREEMENTS: THE CASE OF MARINE STEWARDSHIP COUNCIL CERTIFICATION FOR INDONESIA'S SHRIMP POTENTIAL MARKET

Abstrak Artikel ini membahas analisis biaya dan manfaat dari Marine Stewardship Council (MSC) untuk ekspor udang putih (Litopenaeus vannamei) dan udang windu (Penaeus monodon) dari Indonesia. Penerapan MSC pada produk perikanan memang tidak wajib, tetapi dapat mempengaruhi kinerja eskpor Indonesia. Perhitungan analisa biaya dan manfaat untuk proyek MSC menggunakan beberapa pilihan yang dihitung ke dalam empat komponen analysis yang terpisah (Proyek, Privat, Efisiensi, dan kelompok penerima manfaat). Dengan menggunakan data tahun 2018 dan jangka waktu investasi selama 20 tahun, kajian ini membandingkan hasil investasi yang menerapkan standard MSC dengan hasil investasi yang tidak menerapkan standard MSC dengan mempertimbangkan hambatan dari biaya perdagangan internasional. Secara keselurahan, studi ini menunjukkan bahwa the Net Present Values (NPVs) and Internal Rate of Returns (IRRs) bersifat konsisten untuk semua pilihan analysis. Studi ini juga menyimpulkan bahwa berdasarkan hasil dari analisis pasar, Amerika Serikat adalah pasar yang menjanjikan bagi produk udang Indonesia yang berlabelkan MSC. Pemerintah Indonesia akan menikmati 13% kenaikan pendapatan dari pajak keuntungan bisnis tersebut, meskipun proyek ini tidak memberikan dampak perubahan kepada tenaga kerja tidak terampil. Oleh karena itu, studi ini merekomendasikan pemerintah Indonesia untuk mempromosikan program MSC untuk perikanan berkelanjutan, terutama bagi peningkatan kinerja eskpor udang Indonesia. Kata Kunci: Kebijakan Perdagangan, Perikanan Tangkap, Keberlanjutan, Cost-Benefit Analysis Abstract This paper discusses the cost and benefits analysis of the Marine Stewardship Council (MSC) for Indonesia's exports of white shrimp (Litopenaeus vannamei) and tiger prawns (Penaeus monodon). The MSC adoption is voluntary, but it is likely to affect the performance of Indonesia's exports. We use several options applied separately in four components analysis in performing the social cost and benefit analysis (Project, Private, Efficiency, and Referral Group). Using the 2018 data and a 20-year investment period, this study compares the investment results applying the MSC standard with the results without investing in the MSC procedures concerning the trade cost barriers. Overall, the results reveal that the Net Present Values (NPVs) and Internal Rate of Returns (IRRs) are consistent for all options in all feasibility component analyses. It concludes that based on market analysis, the US market is the promising market as a primary export destination for Indonesian shrimp products with MSC label. The government will benefit by 13% from profit taxes, while this project does not affect unskilled labor benefits. Therefore, it recommends that the Indonesian government take more action to promote the MSC program for sustainable fisheries and boost shrimp export performance.

Downscaling of Future Precipitation in China’s Beijing-Tianjin-Hebei Region Using a Weather Generator

To project local precipitation at the existing meteorological stations in China’s Beijing-Tianjin-Hebei region in the future, local daily precipitation was simulated for three periods (2006–2030, 2031–2050, and 2051–2070) under RCP 4.5 and RCP 8.5 emission scenarios. These projections were statistically downscaled using a weather generator (BCC/RCG-WG) and the output of five global climate models. Based on the downscaled daily precipitation at 174 stations, eight indices describing mean and extreme precipitation climates were calculated. Overall increasing trends in the frequency and intensity of the mean and extreme precipitation were identified for the majority of the stations studied, which is in line with the GCMs’ output. However, the downscaling approach enables more local features to be reflected, adding value to applications at the local scale. Compared with the baseline during 1961–2005, the regional average annual precipitation and its intensity are projected to increase in all three future periods under both RCP 4.5 and RCP 8.5. The projected changes in the number of days with precipitation are relatively small across the Beijing-Tianjin-Hebei region. The regional average annual number of days with precipitation would increase by 0.2~1.0% under both RCP 4.5 and RCP 8.5, except during 2031–2050 under RCP 8.5 when it would decrease by 0.7%. The regional averages of annual days with precipitation ≥25 mm and ≥40 mm, the greatest one-day and five-day precipitation in the Beijing-Tianjin-Hebei region, are projected to increase by 8~30% during all the three periods. The number of days with daily precipitation ≥40 mm was projected to increase most significantly out of the eight indices, indicating the need to consider increased flooding risk in the future. The average annual maximum number of consecutive days without precipitation in the Beijing-Tianjin-Hebei region is projected to decrease, and the drought risk in this area is expected to decrease.
Research on Improvement and Parallelization of K-Means Clustering Algorithm

In view of the traditional K-means algorithm, when facing a large amount of high-dimensional data, due to the difficulty in selecting the initial clustering center and the uncertainty of the K value, the Local optimal solution and slow convergence rate and other issues. This paper proposes a method based on the improved K-means algorithm of the hadoop platform, firstly, the canopy algorithm is used to obtain rough clustering, and then the ISODATA algorithm is used to further dynamically adjust the cluster center and cluster number, So as to optimize the center point list and K value obtained by Canopy algorithm, finally, combine the MapReduce distributed calculation framework and K-means algorithm to realize the optimally designed CI-KMeans algorithm. The experimental results show that the CI-KMeans algorithm solves the problem of the difficulty of selecting the centroid of the K-means algorithm, the unstable clustering effect caused by the distance thresholds T1 and T2 are set too large or too small of the Canopy Kmeans algorithm. Compared with the two algorithms before optimization, the accuracy and speedup ratio have been significantly improved, and the clustering quality has been improved.
Scattering at the junction of a rectangular waveguide and a larger circular waveguide

A full wave, formally exact solution is obtained for the problem of scattering at the junction of a rectangular waveguide and a larger circular waveguide. The general case of an arbitrary offset of the waveguide axes is considered. E-field mode matching over the rectangular aperture of the smaller guide is facilitated by a transformation of the circular cylindrical Bessel-Fourier modal fields of the circular guide into a finite series of exponential plane wave functions in rectangular coordinates. This permits an analytical finite series solution for each of the elements of the E-field mode matching matrix [M] from which the scattering matrix [S] of the junction is easily obtained. Numerical evaluation of the S-parameters for the dominant TE/sub 10/ (rectangular) and TE/sub 11/ (circular) modes in the cases of junctions with no offset and with offset is presented. Moreover, the practical case of a circular cavity resonator with smaller input and output rectangular guides is considered and excellent agreement is found between the calculated and measured S-parameters. >
Non-isolated multi-input–single-output DC/DC converter for photovoltaic power generation systems

A new multi-input non-isolated DC/DC converter with high-voltage transfer gain is proposed in this study. The presented converter consists of the conventional buck–boost and boost converters. All the stages except the last stage are buck–boost converters. The last stage is the conventional boost converter. The proposed multi-input high-voltage gain converter benefits from various advantages such as reduced semiconductor current stress, no limitation for switching duty cycle and wide control range of different input powers. The presented converter can even operate when one or some power input fail to provide energy to the load. The steady-state operation and dynamic modelling of the suggested converter are analysed thoroughly. Experimental results are also provided to verify the feasibility of the presented converter.
Seasonal variation of the effect of extremely diluted agitated gibberellic acid (10-30) on wheat stalk growth - a multi researcher study

Control experiments were performed at different seasons of the year as a follow-up to pilot experiments [1] where a homeopathic high dilution of gibberellic acid had influenced growth in a wheat bio assay (7 days). Grains of winter wheat (Triticum aestivum, Capo variety) were observed under the influence of extremely diluted gibberellic acid (10-30) prepared by stepwise dilution and agitation according to a protocol derived from homeopathy (ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œG30xÃƒÂ¢Ã¢â€šÂ¬Ã‚Â). Analogously prepared water was used for control (ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œW30xÃƒÂ¢Ã¢â€šÂ¬Ã‚Â). Following up on 5 pilot experiments (4 in autumn 2007, 1 in spring 2008), 10 experiments were performed (5 in autumn 2008 or 2009 and 5 in winter 2009 or 2010) with a total of 9 experiments in autumn season (5 researchers, about 9,000 grains), and 6 in winter/spring (4 researchers, about 6,000 grains). Germination rates after 7 days were slightly higher for the autumn experiments (96.1%) than for the winter/spring experiments (94.8%) (p > 0,05), with a non significant trend of more seedlings having germinated in the verum group in the autumn experiments (p > 0,05). All of the 9 autumn experiments (i.e. pilot as well as repetition experiments) showed less stalk growth in the verum group (statistically significant with p < 0.01 in 4, with p < 0.05 in 3 cases, trend in 2 cases). Mean stalk lengths (mm) were 46.97 + 20.50 for the verum group and 50.66 + 19.77 for control (mean + S.D.) at grain level (N = 4,440 per group) and + 3.87 and + 3.38 (+ S.D.) respectively at dish level (217 cohorts of 20 or 25 grains per treatment group). In other words, verum stalk length (92.72%) was 7.28% smaller than control stalk length (100%). The effect size (D means : S.D.), calculated on the basis of dishes, was high (d = 1.02). In contrast, no reliable effect was found in experiments performed in winter/spring (less stalk growth in the verum group in one case, no difference in 2 cases, and more growth in 3 cases). Overall verum stalk length (103.64%) was slightly greater than control stalk length (100%). The effect size, however, was small (d = 0.45). The new data are in line with the 2007 findings, i.e. confirm that gibberellic acid 30x does influence stalk growth.
Basic Empathy Scale: A Systematic Review and Reliability Generalization Meta-Analysis

The Basic Empathy Scale (BES) has been internationally used to measure empathy. A systematic review including 74 articles that implement the instrument since its development in 2006 was carried out. Moreover, an evidence validity analysis and a reliability generalization meta-analysis were performed to examine if the scale presented the appropriate values to justify its application. Results from the systematic review showed that the use of the BES is increasing, although the research areas in which it is being implemented are currently being broadened. The validity analyses indicated that both the type of factor analysis and reliability are reported in validation studies much more than the consequences of testing are. Regarding the meta-analysis results, the mean of Cronbach’s α for cognitive empathy was 0.81 (95% CI: 0.77–0.85), with high levels of heterogeneity (I2 = 98.81%). Regarding affective empathy, the mean of Cronbach’s α was 0.81 (95% CI: 0.76–0.84), with high levels of heterogeneity. It was concluded that BES is appropriate to be used in general population groups, although not recommended for clinical diagnosis; and there is a moderate to high heterogeneity in the mean of Cronbach’s α. The practical implications of the results in mean estimation and heterogeneity are discussed.
