Jagung merupakan salah satu komoditi pangan di Indonesia. Salah satu sentra produksi jagung di Indonesia adalah Provinsi Sumatera Utara. Bulan Juli 2022 terjadi surplus produksi jagung di Sumatera Utara, tetapi terdapat masalah dalam proses budidaya tanaman jagung, di antaranya adalah serangan ulat grayak Spodoptera frugiperda. Pengendalian ulat grayak selama ini menggunakan insektisida kimia. Penggunaan insektisida kimia yang terus-menerus memberikan dampak negatif bagi lingkungan, tanaman maupun kesehatan manusia. Tujuan penelitian adalah mengeksplorasi jenis dan populasi musuh alami hama S. frugiperda yang menyerang tanaman jagung. Penelitian menggunakan metode koleksi secara aktif (metode jelajah) dan pasif. Koleksi secara aktif dilakukan dengan pengambilan secara langsung menggunakan jaring serangga dan pengamatan langsung. Pengambilan data dilakukan dengan menggunakan jaring ayun pada setiap tanaman contoh yang ditentukan. Hasil penelitian menunjukkan bahwa agen pengendali hayati berupa predator yang ditemukan di lapangan total sebanyak 259 ekor, dengan rincian 27 ditemukan pada pengamatan dari jaring serangga dan 232 dari pengamatan langsung. Indeks keanekaragaman pengamatan menggunakan jaring dan pengamatan langsung tergolong sedang; indeks dominasi pengamatan menggunakan jaring tergolong rendah, sedangkan pada pengamatan langsung tergolong tinggi stabil; sementara indeks kemerataan tergolong tinggi stabil. Paederus sp. ditemukan di lahan dengan populasi yang tinggi. ABSTRACTCorn is one of the food commodities in Indonesia, with North Sumatra Province as one of its production centers in Indonesia. In July 2022, there was a surplus of corn yield in North Sumatra, but there were problems in the corn cultivation process, including attacks by armyworms (Spodoptera frugiperda). Control of armyworms has ordinarily used chemical insecticides. But, continuous use of chemical insecticides has negative impacts on environment, plants and human health. The aim of the research is to explore the types and populations of natural enemies of the S. frugiperda pest that attack corn plants. The research uses active (exploration method) and passive collection methods. Active collection was carried out by direct collection using insect nets and direct observation. Data collection was carried out using a swing net on each specified sample plant. The research results show that a total of 259 biological control agents in the form of predators were found in the field, with details of 27 found from observations from insect nets and 232 from direct observation. The diversity index for observations using nets and direct observations is moderate; the dominance index for observations using nets is classified as low, while direct observation is classified as high and stable; while the equality index is relatively high and stable. Paederus sp. were found in areas with high populations.

Somatotypological features of the body can be considered as a lever of sports achievements, because they have an effect on the efficiency of the energy supply system, physical capacity, ability to adapt, and the state of the cardiovascular system. The purpose of our work is to reveal the correlations between the amplitude parameters of the crus rheovasogram and anthropometric indices in young volleyball players women of different somatotypes. A comprehensive clinical and laboratory study of the state of health and physical development of 108 volleyball players women aged 16-20 years (youth period of ontogenesis) of high sports ranks (from II adult to masters of sports) was conducted. Rheovasographic parameters of the crus in volleyball players women were determined by the method of tetrapolar rheocardiography on a certified computer diagnostic multifunctional complex. Anthropometric determination of the total dimensions of the body and chest, pelvis, limbs, and head was performed according to the recommendations of Shaparenko P. P. (2000), somatotypological – according to the Heath-Carter calculation method (1990). After somatotyping, it was established that 28 women volleyball players belonged to the mesomorphic type of constitution, 27 women athletes were assigned to the ectomorphic and ecto-mesomorphic somatotypes each, and 26 women volleyball players belonged to the medium intermediate type. The analysis of the obtained results was carried out in the license program "Statistica 5.5" using correlation analysis according to Spearman. We found that highly professional women volleyball players, who have different body types, differ in the strength and number of significant correlations between the amplitude rheovasographic parameters of the crus and anthropometric dimensions. The most numerous (18.64 % of the possible correlations, of which 6.82 % are reliable) and the strongest (3 strong with a correlation coefficient from -0.64 to -0.73) correlations between the amplitude indicators of the crus rheovasogram and parameters of the external body structure were recorded in volleyball players women of the middle intermediate somatotype. Ectomorphs had the lowest number and strength of relationships (3.18 % of possible correlations, only 1 reliable). Individual longitudinal dimensions of the body, chest girths and its diameters, transverse dimensions of the pelvis, and skinfold thickness were most often correlated with the amplitude indicators of the crus rheovasogram in women volleyball players of various constitutional types. Determining the features of the correlations is the basis for assessing the harmony of the physical development of women volleyball players and conducting further statistical modeling to determine their appropriate crus rheovasographic indicators.

This study aimed to develop and validate a bone marrow edema model using a magnetic resonance imaging-based radiomics nomogram for the diagnosis of osteoarthritis. Clinical and magnetic resonance imaging (MRI) data of 302 patients with and without osteoarthritis were retrospectively collected from April 2022 to October 2023 at Longhua Hospital affiliated with the Shanghai University of Traditional Chinese Medicine. The participants were randomly divided into two groups (a training group, n = 211 and a testing group, n = 91). We used logistic regression to analyze clinical characteristics and established a clinical model. Radiomics signatures were developed by extracting radiomic features from the bone marrow edema area using MRI. A nomogram was developed based on the rad-score and clinical characteristics. The diagnostic performance of the three models was compared using the receiver operating characteristic curve and Delong’s test. The accuracy and clinical application value of the nomogram were evaluated using calibration curve and decision curve analysis. Clinical characteristics such as age, radiographic grading, Western Ontario and McMaster Universities Arthritis Index score, and radiological features were significantly correlated with the diagnosis of osteoarthritis. The Rad score was constructed from 11 radiological features. A clinical model was developed to diagnose osteoarthritis (training group: area under the curve [AUC], 0.819; testing group: AUC, 0.815). Radiomics models were used to effectively diagnose osteoarthritis (training group,: AUC, 0.901; testing group: AUC, 0.841). The nomogram model composed of Rad score and clinical characteristics had better diagnostic performance than a simple clinical model (training group: AUC, 0.906; testing group: AUC, 0.845; p &lt; 0.01). Based on DCA, the nomogram model can provide better diagnostic performance in most cases. In conclusion, the MRI-bone marrow edema-based radiomics-clinical nomogram model showed good performance in diagnosing early osteoarthritis.

Fungal diseases cause substantial loss to agricultural crops, affecting both quantities and quality. Although several methods are used for preventing disease incidence, fungicides remain crucial for higher yields and better quality. But in the past, the efficacy of several fungicides has decreased due to increased cases of fungicide resistant. In our pursuit of new effective fungicides, we synthesised a series of twenty 2-Indazol-1-yl-chromen-4-one derivatives (6a- 6t). The characterization of synthesized compounds was performed by several spectroscopic methods including Infrared, Nuclear Magnetic Resonance (1H and 13C) and HRMS. Out of 20 synthesised compounds, 19 (6b- 6t) were found to be novel. All synthesised indazolylchromones showed very good antifungal activity against Sclerotium rolfsii and Fusarium oxysporum. Among the tested compounds, 6t and 6f exhibited very good fungicidal activity against S. rolfsii with an ED50 of 10.10 mg L-1 and 16.18 mg L-1, respectively. In case of Fusarium oxysporum compound 6f displayed good’ activity with an ED50 value of 27.82 mg L-1. Molecular docking study was done to predict the binding sites of most active compounds, 6t and 6f with Cytochrome P450 14alpha -sterol demethylase (CYP51) enzyme using molsoft software. The acute toxicity predictions the of synthesized compounds for fish (LC50,96 Hr), daphnid (LC50, 48 Hr) and green algae (EC50, 96Hr) and the chronic toxicity predictions (ChV) were assessed using Ecological Structure Activity Relationship (ECOSAR) model. As per ECOSAR prediction, all the chemicals are inside AD and not missing predictions.

IntroductionCrowdsourcing software development (CSSD) is an emerging technique in software development. It helps utilize the diversified skills of people from across the world. Similar to all emerging techniques, CSSD has its own benefits and challenges. Some unique challenges arise when CSSD is used with Agile methodology. This is because many characteristics of CSSD differ from Agile principles. CSSD is a distributed approach where workers are unknown to each other, whereas Agile advocates teamness and is mostly suitable for colocated teams. Many organizations are now combining crowdsourcing software development (CSSD) and Agile methodologies, yet there is limited understanding on the implications of this integration. It is crucial to emphasize the human factors at play when implementing Agile alongside CSSD. This involves considering how teams interact, communicate, and adapt within these frameworks. By recognizing these dynamics, organizations can better navigate the complexities of integrating CSSD and Agile, ultimately fostering more efficient and collaborative development processes.MethodThis study aimed to explore the human factors involved in the integration of CSSD with Agile, by identifying the challenges that practitioners face when they follow Agile with CSSD and the strategies they follow. The study contributes by providing an in-depth understanding of a new approach, CSSD, integrated with Agile. The study also explores the challenges faced by practitioners that are not already enlisted.Results and discussionThese identified challenges are grouped into six different categories, which are trust-related challenges, coordination and communication challenges, organizational challenges, task-related challenges, project-related challenges, and some general challenges. Strategies for each of these categories of challenges are also identified. The list of challenges and strategies identified in this study can be helpful in further research on CSSD and Agile integration. The practitioners can also follow these strategies to reduce the impact of challenges they face while they perform CSSD along with Agile.
The contribution of psychological capital and parental age to job satisfaction: a comparison of parents of children with autism spectrum disorder and parents of typically developing children
Authors: Hazan-Liran Batel 
Published: June 2024

IntroductionA recent concern is the frequency with which children are classified as having autistic spectrum disorder (ASD). Parents of children with ASD report difficulties in all areas of life, including the workplace. Previous studies show psychological capital (PsyCap), defined as a combination of hope, self-efficacy, optimism and resilience, is a key factor in job satisfaction and coping in numerous areas. I examined the relations of PsyCap with job satisfaction in parents of ASD children and parents of typically developing children.MethodsThe study involved 141 participants, 127 women, 14 men. About half (n = 69) had a child with ASD (mean age 41.41, SD 5.79), and about half (n = 72) had a typically developing child (mean age 43.65, SD 7.29). Measurements comprised the Job Satisfaction Questionnaire and the PsyCap questionnaire (PCQ). Data were collected online.ResultsPositive relations between PsyCap and job satisfaction was found for both groups. Parents of children with ASD had higher levels of resilience than their comparators. With increased age, parents of children with ASD reported decreased job satisfaction; parents of typically developing children reported increased job satisfaction.DiscussionThe study expands the understanding of how parents of children with ASD cope at the occupational level. Their job satisfaction decreases with age. Organizations who employ parents of children with special needs in general and ASD in particular should take this into account and discuss their employees' changing needs to maximize their job satisfaction and give them room for professional development under flexible conditions.

Published: June 2024

BackgroundPrevious observational studies have shown conflicting results of vitamins supplementation for thyroid diseases. The causal relationships between vitamins and thyroid diseases are unclear. Therefore, we conducted a two-sample bidirectional Mendelian randomization (MR) study to explore association of circulating vitamin levels with thyroid diseases.MethodsWe performed a bidirectional MR analysis using genome-wide association study (GWAS) data. Genetic tool variables for circulating vitamin levels include vitamins A, B9, B12, C, D, and E, Genetic tool variables of thyroid diseases include autoimmune hyperthyroidism, autoimmune hypothyroidism, thyroid nodules (TNs), and Thyroid cancer (TC). Inverse-variance weighted multiplicative random effects (IVW-RE) was mainly used for MR Analysis, weighted median (WM) and MR Egger were used as supplementary methods to evaluate the relationships between circulating vitamin levels and thyroid diseases. Sensitivity and pluripotency were evaluated by Cochran’s Q test, MR-PRESSO, Radial MR, MR-Egger regression and leave-one-out analysis.ResultsPositive MR evidence suggested that circulating vitamin C level is a protective factor in autoimmune hypothyroidism (ORIVW-RE=0.69, 95%CI: 0.58-0.83, p = 1.05E-04). Reverse MR Evidence showed that genetic susceptibility to autoimmune hyperthyroidism is associated with reduced level of circulating vitamin A(ORIVW-RE = 0.97, 95% CI: 0.95–1.00, p = 4.38E-02), genetic susceptibility of TNs was associated with an increased level of circulating vitamin D (ORIVW-RE = 1.02, 95% CI: 1.00–1.03, p = 6.86E-03). No causal and reverse causal relationship was detected between other circulating vitamin levels and thyroid diseases.ConclusionOur findings provide genetic evidence supporting a bi-directional causal relationship between circulating vitamin levels and thyroid diseases. These findings provide information for the clinical application of vitamins prevention and treatment of thyroid diseases.

Introduction: High Alpine regions show a great potential for solar photovoltaic electricity production in winter due to the reflective properties of snow and the larger number of sun hours compared to lower urban and peri-urban regions. In countries with a pronounced deficit in domestic electricity production such as Switzerland, utility-scale projects of Alpine-PV power plants are now flourishing. The harsh environmental conditions and the complexity of the high-Alpine topography however challenge the conventional design practices. In this context, the main question the article addresses is the representation of test-scale measurement in the performances of Alpine-PV, utility-scale power plants.Methods: This article focuses on the comparison between long term tests and the first Alpine-PV utility-scale power plant in Switzerland.Results: The results show that the main performance indicators such as the Alpine-to-Midlands final yield ratio or the winter fraction, do scale. However, absolute final yield values are consistently lower at the utility scale.Discussion: The paper discusses the possible impacts of the complex Alpine topography as constraint for the design of the larger extent of utility-scale power plants as well as the influence of scale on the snow induced losses.
