A Simple Preprocessing Method Enhances Machine Learning Application to EEG Data for Differential Diagnosis of Autism
Authors: Grossi Enzo , White Rebecca , Swatzyna Ronald J.
Published: January 2024

A new pre-processing approach of EEG data to detect topological EEG features has been applied to a continuous segment of artifact-free EEG data lasting 10 minutes in ASCII format derived from 50 ASD children and 50 children with other Neuro-Psychiatric Disorders (NPD), matched for age and male/female ratios.

Each EEG is transformed in a triangular matrix of 171 values expressing all reciprocal Manhattan distances among the 19 electrodes of to the international 10-20 system. From this matrix, the minimum spanning tree (MST) is calculated. Electrode identification serial codes sorted according to the decreasing number of links in MST, and the number of links in MST are taken as input vectors for machine learning systems. 

Machine learning systems have been applied to build up a predictive model to distinguish between the two diagnostic classes (autism vs NPD) following a rigorous validation protocol.

The best machine learning system (KNN algorithm) obtained a global accuracy of 93.2% (92.37 % sensitivity and 94.03 % specificity) in differentiating ASD subjects from NPD subjects.

The results obtained in this study suggest that, thanks to the new pre-processing method introduced, there is the possibility to discriminate subjects with autism from subjects affected by other psychiatric disorders with a modest computational time reducing the information to 38 figures.
When a Cluster Is a Cluster
Authors: Grossi Enzo
Published: January 2024

The study of epidemic spread has generally relied on the description of certain number of cases of an infectious diseases like COVID-19 in relation to time occurrence of disease manifestations rather than to the exact place of occurrence. In recent times, computer generated dot maps have facilitated the modeling of the spread of infectious epidemic diseases either with classical statistics approaches or with artificial ``intelligent systems''. When new cases occur in relatively distant locations, it is very difficult to determine whether they constitute a cluster. The identification of the spatial clustering should be the first step when developing effective policies to manage and control any new epidemic.

Published: January 2024

The current study examines how conservative social ideologies and religiosity interact to predict lower levels of knowledge, social intolerance, and negative attitudes toward interacting with transgender and gender nonbinary (TGNB) individuals. An online cross-sectional research was conducted between March 2 and June 2, 2021. Two hundred and sixty-six participants were recruited for this study. The mean age was 29.30 (_SD_ = 11.98, age range: 18-60 years). The study used a between-subject correlational design. A multiple regression model was used to predict participants’ TGNB Knowledge, Attitudes, and Beliefs from the other research variables based on the importance of associations. We examined our hypotheses regarding the moderating role of conservative values and political positioning on the linkage between religiosity and TGNB knowledge, social tolerance, and attitudes toward interacting with TGNB individuals using PROCESS (Model 1). This study’s results show that the conservative cis-normative system (i.e., religiosity, conservative values, and right-wing political orientation) seems significantly linked to TGNB social intolerance.

Published: January 2024

Disturbances in iron regulation has been described in diverse chronic liver diseases other than hereditary hemochromatosis, and iron toxicity may worsen liver injury and disease outcomes. In relation to the new umbrella terminology for steatotic liver disease (SLD), we aimed to elucidate the iron burden status of the SLD subgroups: metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic alcohol-related liver disease (Met-ALD). We performed a prospective, multicenter study in the hepatology care setting, including 189 biopsy-proven SLD patients, 82% MASLD and 18% MetALD, with paired liver biopsy and Magnetic Resonance (MR) imaging. We evaluated the presence of iron overload according to predefined criteria (histology, serum ferritin and MR-R2*) and divided all the participants according to the new SLD classification. Iron dysregulation was common, up to 20% in steatotic liver diseases. A total of 19% had metabolic hyperferritinemia, 22% had increased iron deposits in tissue slides, and 26% had increased MR-R2* as biomarker of hepatic iron content. The iron burden of the MetALD group was higher than those of the MASLD group. The MetALD group had a significantly higher iron deposits on biopsy (p< 0.001) and serum ferritin levels (p = 0.016) than the MASLD group. There were no differences between both subgroups in terms of R2* imaging biomarker. Further evaluation of iron overload as a co‐morbid factor should identify the key pathogenic disturbances, establish the risk threshold for iron toxicity, and promote pharmacological interventions.

The rubber tree (Hevea brasiliensis) is one of the most valuable members of the genus Hevea because it has high latex production and the latex exploited from the rubber tree is the primary source of natural rubber. Rubber trees are often damaged and exposed to pathogen attacks through wounds during and after tapping. Gene expression studies help us to gain insights into molecular mechanism underlying the responses of this plant species to stress signals such as wounding and pathogenicity. To ensure the reliability of gene expression measurements, quantitative procedures, particularly reverse transcription - quantitative PCR (RT-qPCR), require the normalization of the expression level of a gene of interest (target gene) to that of a stably expressed internal reference gene. Selecting and validating an appropriate reference gene is thus an essential step before conducting RT-qPCR experiments to look for differences in transcriptional expression of the target gene in H. brasiliensis under specific experimental conditions. Here, the transcriptional expression of ubiquitin-conjugating enzyme 2b (HbUBC2b) was measured by RT-qPCR in a set of 12 RNA samples derived from the bark of the rubber tree H. brasiliensis (clone RRIV 209) exposed to mechanical wounding, and stress signal molecules like methyl jasmonate (MeJA). With the aim of estimating PCR efficiency, and thus to include it in further analysis procedures, a standard curve assessment has been developed using HbUBC2b-specific primers and a 5-fold dilution of cDNA as template for qPCR reactions. The amplification efficiency (102,9%), as well as the R2 value (0,9992) are within the recommended range (90-110%). The HbUBC2b gene was shown to be stably expressed across control and treatment groups, and therefore could be used as a reference gene for quantitative gene expression normalization in H. brasiliensis (clone RRIV 209) under mechanical wounding or methyl jasmonate treatment.

In this study, cellulose nanocrystals (CNC) and ZnO-CuO nanostructure were successfully prepared by acid hydrolysis and hydrothermal methods, respectively. CNC had been derived through the hydrolysis reaction by sulfuric acid from the pure cellulose isolated from Vietnamese coconut husk fiber. CNC was then used as a starting material polymer for the preparation of ZnO-CuO/CNC composite. The morphological and structural measurement of CNC, ZnO/CuO and ZnO-CuO/CNC composite were investigated by FESEM-EDX, EDX mapping, FT-IR and XRD analyses. The analysis showed that the poly-dispersed, rough and rod like CNC possessed an average length of150 nm and average diameter of15 nm. EDX and XRD spectra showed that the obtained ZnO-CuO/CNC exhibited highly purified and belonged to the type of cellulose of grate I with a monoclinic structure. Via the hydrothermal method, ZnO-CuO/CNC flower-like microstructures composed of hierarchical three-dimensional (3D) aggregated hexagonal. The cluster architectures of ZnO/CuO were formed at 120 oC in 10 h. A possible growth mechanism for the controlled organization of primary building units into ZnO-CuO nanostructure and 3D flower-like ZnO-CuO/CNC architectures was proposed. The result demonstrated that the prepared ZnO-CuO/CNC composite exhibited a high removal efficiency (93%) of methylene blue of the concentration of 20 mg/L after 30 min treatment.

Facing the current trend of climate change, bank erosion occurs more often in river bank and coastal areas. This problem not only causes loss of land but also damages houses and human lives. Can Gio is a coastal district on the southeast coast of Ho Chi Minh City, an area that has been severely eroded, affecting people's lives and depleting the local economy This paper presents the results of monitoring the shoreline changes in Can Gio district from remote sensing image analysis techniques. The Landsat satellite image was used in combination with a calculation technique based on the water spectrum index to extract the shoreline for the period 1998 - 2019. The results show that, in the whole area, the erosion process dominates with the area of erosion at different stages always being higher than that of accretion; Specifically, within 21 years, the area of erosion occurred 1.8 times more than that of accretion. The landslide area that has accounted for the highest proportion is Thanh An commune with the rate of 29% compared to the area of the whole district. Meanwhile, Long Hoa commune had the largest accretion area with the rate of about 35% compared to the area of the whole district. The research results aim to assist people in coastal monitoring and management to minimize damage to human and ecosystems.

Saltwater intrusion in the Mekong Delt, an urgent problem, affected the growth of fruit trees in general and Citrus latifolia (Yu. Tanaka) Tanaka in particular. Sodium chloride in saline soils cause the water stress on plant roots leading to the leaf senescence and death of plant. Therefore, in this study, the salinity tolerance of the studied plant was investigated under conditions of additional sodium chloride in soil at various concentrations (from 0 to 16 g/L) to determine the salinity tolerance threshold of the plants, and then the roots were water irrigated and the leaves were sprayed by KNO3 solution at concentrations from 0 to 10 g /L to improve the salinity tolerance. The results showed that after 2 weeks of treatment of sodium chloride 4‒16 g/L, the increased saline caused the osmotic stress, increased the defoliation but reduced the leaf renewal, the fresh weight, the chlorophyll index, the Citrus latifolia growth, and decreased the aperture size and the photosynthetic intensity over time. The salinity stress promoted the ligninization in the rhizosphere parenchyma cells, reduced the root renewal and elongation. In addition, treatments for the plant recovery were also carried out by irrigating at the roots and spraying KNO3 10 g/L solution on the leaves. After 3 and 6 weeks, irrigation treatments could only recover plants from sodium chloride at 4‒8 g/L, indicating by the new leaf formation, the maintenance of the chlorophyll content in leaves and the decrease of the proline content. Sodium chloride solutions of 12 and 16 g/L caused a complete death of plants which could not be recovered after 6 weeks of watering. The treatment of sodium chloride combining with KNO3 10 g/L spray helped the aperture opening and increasing the proline accumulation in leaves and roots. In addition, role of endogenous plant growth regulators was also discussed to clarify physiological changes in saline stress conditions.

The goal was to evaluate the performance of the state-of-the-art algorithms. A secondary goal was to try to improve upon the result of a method that was used in a study similar to the one used in this work. This paper presented the building of multi-state datasets relating to eye behaviors and facial expressions. Signals were recorded and stored by the connection of a channel-less mobile device. Z-score, max-min normalization techniques were used to optimize data. The cross-validation technique divided the data into training/testing segments. The features of the electrical brain signals (delta, theta, alpha and beta band) were analyzed by the Daubechies wavelet transform method. The extracted time and frequency domain features calculate total energy, detailed component energy, approximate component energy, relative energy. Three algorithms, support vector machine, k-nearest neighbor, and ensemble algorithm, were used to develop into 17 models to optimize the classification efficiency of the machine learning algorithms. Parameters of these models were surveyed and optimized to propose a best classification one for the Data-021 dataset. The Subspace ensemble model was proposed because its model efficiency was more than 87,7%.

In this research, we used first principles methods with density functional theory (DFT) to evaluate simultaneously the electronic and optical properties of defect-free and single-vacancy blue phosphorene quantum dots. We used the generalized gradient approximation of the Perdew-Burke-Ernzerhof (PBE) functional as exchange-correlation functional. We have shown that the band gaps of these quantum dots can be varies in between 2.56 eV and 2.80 eV and the band gap decreases with increasing the system sizes. In the presence of single vacancy, the band gap significantly shrinks resulting from the shift of the conduction band towards the valence band. We also observed additional polaron states close to the Fermi level, indicating the existence of dangling bonds being established by the unbalanced charge Phosphorous atoms surrounding the defect sites. The absorption coefficent increased noticably in the visible light range. The appearance of the polaron states resulted in newly formed absorption peaks in the visible light range. Our results showed the clear effect of defect on light conversion efficiency of solar panels embedding blue phosphorene quantum dots.
Survey the effect of X-ray irradiation dose on the germinating ability of petunia's seed
Authors:   Dalat University, Lam Dong, Vietnam, An Sơn Nguyễn
Published: January 2024

Petunia is an immigrant flower with various colors. However, Petunia seed has a low germination rate. Thus, the stimulation of the germination plays an important role to increase the yield and this would bring economic efficiency. Many traditional methods have been used to increase the germination such as selecting the optimal conditions of the medium such as temperature, pressure, humidity, or chemical treatment. Nowadays, the X-ray irradiation is used to the germinating stimulation and mutation studies. Some advantages of using a X-ray generator as the source irradiation are easily changing the emitted energy, the dose and dose rate as well as when not in use it is not neccesary to shield the the apparatus. In this study, a X-ray generator MBR-1618R-BE (Hitachi, Japan) was used with the emission energy of 160 keV and the irradiated dose would be changed from 1 Gy to 1500 Gy. Petunia seeds were obtained from flower seeds grown in natural conditions at Da Lat city. Petunia seed samples were irradiated at doses of 1, 2, 3, 4, 5, 6 or 7 Gy to evaluate the ability to stimulate the germination and as well as at the high doses of 100, 200, 300, 400 or 500 Gy to determine the LD50 value. The results showed that at the dose of 2 Gy, the germination rate reached more than 80% of the seeds, approximately 4 times higher than that of the control sample and the LD50 value was 126 Gy.

Published: January 2024

Nitrate content (NO3-) is one of the important indicators to assess the quality of leafy vegetables. Many studies have shown that vegetables in local markets containing high levels of nitrate that induce harmful effects on human health. In Vietnam, publications on the correlation between NO3-/+NH4 ratio and the nitrate accumulation are limited. Mustard green (Brassica juncea L.) is a popular vegetable and has a high nutrient (rich in fiber and micronutrients). However, the effect of nitrogen on the nitrate accumulation by hydroponic has not been elucidated. In this study, mustard green was grown in four media with different NO3-/+NH4 ratios (2/1; 1.5/1; 3/1, and 4/0) in the hydroponic reflux system. Results showed that the nitrogen requirement of mustard green depended on growth stages. Mustard green needed a low NO3-/+NH4 ratio at the slow growth stage (seedlings) and a high NO3-/+NH4 ratio at the fast one. In addition, the increase of the nitrate content also improved the chlorophyll content in the leaves. The complete removal of +NH4 in the medium stimulated the nitrate accumulation in leaves. The study showed that the suitable hydroponic medium for mustard green was MS medium supplemented with twice KNO3. The KNO3 addition in the hydroponic medium increased the chlorophyll content, the fresh weight, and ensured the content of nitrate (417.59 ± 10.51 mg/kg) within the allowable limits (< 500 mg/kg).

Yacon (Smallanthus sonchifolius), a plant traditionally grown in the Northern and Central Andes, is recently cultivated in Vietnam. The edible storage roots of yacon contain a large amount of carbohydrate during the form of indigestible fructooligosaccharide (FOS), which functions as a prebiotic and gives positive effect during the treatment of obesity, diabetes, and colorectal cancer. Thus, yacon root is expected to be a good dietary supplement for patients with these diseases. There has been limited research about the impacts of microorganisms on the tuberous root formation of yacon. Therefore, this paper presents the enumeration of aerobic bacteria in the root area at the two growing stages, before and in the early stage of the tuberous root formation, of yacon by MPN (Most Probable Number) method. The obtained results show a significant change on the amount carbohydrate metabolism bacteria presence in yacon roots between the two growing stages. Besides, there are more carbohydrate metabolism bacteria (9,3 x 105 MPN/mL) in tuberous root than protein metabolism bacteria (9,3x103 MPN/mL). The isolation of aerial bacteria from yacon roots found 22 strains, which are assigned into the 10 genera including Burkholderia, Caulobacter, Myroides, Pantoea, Pseudomonas, Stenotrophomonas, Kosakonia, Rhizobium, Enterobacter, and Klebsiella based on the phylogentic analysis of the so-called 800R 16S rRNA gene sequences. The appearance of those genera in difference parts of yacon root is not the same. The presence of difference genera is also shown in the roots at the two growing stages.

Can Labeling Policies Facilitate Sustainable Consumption and Production?: A Case Study of a Government-led Ecolabeling Program in Indonesia
Authors:   Korea Association of International Development and Cooperation, Joo Dayoon , Yoon Semee
Published: January 2024

Purpose: This study aims to evaluate the effectiveness of a top-down approach to facilitate sustainable consumption and production through an evaluation of the Indonesian ecolabeling policy, Ekolabel Indonesia.
Originality: Academic assessments of eco-labels systematically take place in the developed country context. However, persistent environmental threats are driving developing countries, such as Indonesia, to adopt top-down approaches to ecolabeling strategies. Consequently, the emergence of such government-led interventions signals the need for thorough examination.
Methodology: This study analyzes the policy through a program theory-driven evaluation. While there are various adaptations of this conceptual analytical model, this study utilizes two complementary frameworks: the Theory of Change (ToC) framework and the Multi-Criteria Policy Evaluation (MCPE) approach using Mickwitz’s (2003) valuation multi-criteria.
Result: The study has four main findings: firstly, the scope of the ecolabel-related Indonesian National Standards remains limited to make a significant impact on the environment. Secondly, there needs to be a sharp uptake of the Ekolabel logo among a wide variety of products. Thirdly, transparency, in the form of data accessibility, must be improved to ensure that stakeholders are held accountable to the policy’s outputs. Lastly, the Ministry must ensure that smaller businesses are not marginalized from the initiative due to de facto barriers such as high conformity assessment costs by private certification bodies.
Conclusions and Implication: Ekolabel Indonesia has paved the way for other Sustainable Consumption and Production initiatives in Indonesia. However, the Indonesian government needs to address these fundamental issues that compromise its ability to maximize impact. Significant effort needs to be directed towards increasing participation and providing support for equitable development.

Published: January 2024

Cutting-edge technologies focusing on optical efficiency, data rates, and transmission power efficiency are propelling the evolution of multiple-input-multiple-output (MIMO) systems. These innovations facilitate higher aggregation rates, particularly beneficial in large MIMO generation environments. However, the fixed nature of MIMO results in a smaller channel shape in the spatial domain, limiting dynamic adoption in various 2D channels. Despite this constraint, the distinctive channel characteristics of MIMO present opportunities for significant improvements in 5G network capacity. This study explores and compares the channel nature of MIMO, shedding light on its potential to optimize network performance in heterogeneous environments, marking a noteworthy stride in the pursuit of enhanced wireless communication technologies.

Вивчання розподілу населення за релігійною ознакою в країнах пострадянського простору, в тому числі в Україні та на Закарпатті, надзвичайно ускладнене відсутністю статистичного відліку конфесійного складу, а також відповідних питань в програмі переписів населення. Для хоча б часткового усунення браку даних, який утворився внаслідок серійного перенесення чергового перепису населення в Україні, в 2017 році проведено демографічне дослідження методом анкетного опитування під назвою «SUMMA 2017». Головною метою дослідження було оцінити чисельність та демографічні характеристики закарпатських угорців, крім того стало можливим уточнити фрагментарні відомості стосовно конфесійного складу етнічної спільноти. В результаті опитування отримано більш точну та детальну в порівнянні з попередніми оцінками картину щодо частки окремих конфесій серед угорців Закарпаття, як в розрізі області, так і окремих поселень. Представлено географічні особливості поширення трьох найчисельніших релігійних спільнот – реформатської, римо-католицької та греко-католицької. Розглядаються особливості змін релігійного складу за останні десятиріччя, а також їхні можливі чинники. На завершення проаналізовані взаємозв’язки окремих соціально-демографічних показників із конфесійною приналежністю.

На території Закарпаття щорічно реєструються сотні місцевих підземних поштовхів, серед яких виділяються потужніші землетруси, що відчуваються людьми та є індикатором підвищення напружено-деформованого стану порід. В роботі проведено вивчення впливу сучасних горизонтальних рухів кори в регіоні на прояви місцевої та регіональної сейсмічності, аналіз відгуку на них геофізичних полів, зокрема варіацій радіоактивного фону середовища в центральній частині Закарпаття. Сучасні горизонтальні рухи кори в зоні Оашського глибинного розлому за 2022 рік, отримані на пункті деформометричних спостережень «Королеве», представлені розширеннями порід величиною :+1261 нстр. За цей період на території Карпатського регіону зареєстровано 50 місцевих землетрусів різної магнітуди та глибини. Вказано на існування зв'язку інтенсивних рухів кори та інтервалів підвищеної сейсмічності: землетруси реєструються в періоди інтенсивного стиснення порід, зокрема в зоні Оашського глибинного розлому. Геомеханічні процеси викликають зміни фізичних характеристик верхніх шарів земної кори, які проявляються в змінах параметрів досліджуваних геофізичних полів, параметрів радіоактивного фону середовища, зокрема гама-випромінювання. Ці події в часовому інтервалі корелюються, радіоактивний фон середовища в період динамічних геомеханічних процесів проявляється через реєстрацію аномальних величин, що може бути застосовано при побудові моделі геодинамічних та сейсмічних процесів в екологічно небезпечних регіонах. Отримані дані доповнюватимуть результати інших досліджень геофізичних процесів та факторів впливу на них при вивченні процесів підготовки та прояву місцевої сейсмічності. Важливо проведення подібних досліджень в північно-західній частині та південно-східній частині Закарпатського внутрішнього прогину, які розкриють нам характер рухів кори в як у вертикальних так і горизонтальних напрямах.
ВПЛИВ ЧАТ-БОТІВ ЗІ ШТУЧНИМ ІНТЕЛЕКТОМ НА ПРОЦЕС ВИКЛАДАННЯ КУРСІВ ІЗ ПРОГРАМУВАННЯ

Приблизно з листопада 2022 року ChatGPT (Generative Pre-trained Transformer) став доступним у більшості країн світу. Так почалось стрімке поширення штучного інтелекту (ШІ) в інформаційному просторі. Відтепер багато трудомістких завдань стало можливим доручати штучному інтелекту. Це швидко опанували, наприклад, копірайтери, журналісти, автори текстів з різноманітних сфер життя. Звісно, далеко не завжди в кінцевому результаті отримується якісний продукт. Але в разі відповідального ставлення компетентних фахівців до текстів, згенерованих штучним інтелектом, все ж можна досягати гарних результатів від співпраці природного і штучного інтелекту. Часто штучний інтелект стає корисним і в освіті. Але разом з вигодами з’явились і нові виклики. Зокрема, у питанні захисту авторських прав і в галузі освіти. Дуже вагомий вплив штучний інтелект має на викладання курсів з інформаційних технологій. Далеко не завжди цей вплив є позитивним. У роботі окреслюється вплив ШІ на освітню діяльність. Йдеться як про процес вивчення, так і про процес викладання. До уваги брались два найбільш розповсюджених чат-боти: ChatGPT і Google Bard. Метою роботи є аналіз шляхів послаблення негативного впливу ШІ, а саме – яким чином зменшити ризик того, що студенти воліють надмірно користуватись послугами чат-ботів, замість того, щоб виконувати завдання самостійно. Результати дослідження здобуті впродовж останніх років, при викладанні курсів з програмування на Python, JavaScript і PHP. Оскільки така проблема постала тільки у 2023 році, тож системних дієвих рішень, випробуваних часом, ще не напрацьовано. У роботі робляться висновки про те, яким чином можна якщо не усунути, то хоча б послабити негативний вплив чат-ботів на бажання студентів самостійно виконувати завдання з програмування. Наводиться також ряд порад щодо підбору завдань для лабораторних, контрольних і залікових робіт. Ці поради можуть бути корисними для учителів навчальних закладів різного рівня. І зрештою вони можуть позитивно вплинути на рівень академічної доброчесності студентів.

Мета роботи провести аналіз досліджень, які стосуються моделювання процесів формування гетероструктур. Визначити особливості розвитку даної тематики у світі та пошуку шляхів ефективного розвитку в Україні. Проведено аналіз публікацій, індексованих у наукометричній базі Scopus за ключовими словами «modeling of heterostructures» і «modeling of heterostructure formation». Для порівняльного аналізу відібрано статті з пошуку у назві статті, анотації і ключових словах у 2 039 наукових працях за останні 20 років. Проаналізовано країни і наукові організації авторів, наявність фінансової підтримки досліджень, самі публікації, а також найпопулярніші і найцитованіші видання, у яких здійснено публікацію, їх кількість та приналежність до галузі знань. Проаналізовано публікації авторитетних світових науковців у галузі моделювання гетероструктур для розуміння закономірностей підтримки та розвитку цього напряму у світі і в Україні, визначення перспектив нових досліджень. Розглянуто особливості міжнародної співпраці, окреслено коло провідних публікацій у науковій галузі, проаналізовано фактори впливу вчених різних країн на розвиток цієї галузі. Сформульовано пропозиції для покращення поширення результатів вітчизняних вчених у світовій науковій спільності за цим напрямом. Світові науковці намагаються знайти практичне застосування результатів своїх досліджень. Також, часто такі напрями визначаються наявною матеріальною базою, розробленим програмним забезпеченням, або публікаціями у співпраці вчених з різних країн, де кожна наукова група чітко виконує свою частину роботи. Із аналізу за двома пошуковими запитами із 2 039 і 166 наукових праць за період 2002-2023 рр. більше половини всіх робіт незмінно опубліковано вченими зі США. Установи, де проводяться передові дослідження з даної тематики, зосереджено у провідних науково-дослідних центрах: CNRS Centre National de la Recherche Scientifique, Chinese Academy of Sciences, Purdue University, Massachusetts Institute of Technology, National University of Singapore, Cornell University тощо.

Let's wait for the evening: nocturnal copulation in a tropical damselfly Phylolestes ethelae (Odonata, Synlestidae)

Sexual selection is one of the main causes of the diversity of reproductive behaviours observed intra- and interspecifically. Here we study the reproductive behaviour of a unique species, Phylolestes ethelae, the only member of the family Synlestidae (Odonata) found in America. Our hypothesis was that the phylogenetic uniqueness of this species and the fact that it lives on an island would produce novel behaviours worth protecting as they are a part of the biodiversity. Between 2017 and 2019 we studied a population of P. ethelae in the National Park Armando Bermúdez in the Dominican Republic by means of mark-recapture techniques and focal observations. The survival rate was estimated as 0.953 ± 0.012 (SE), which translates into an expected lifespan of 20.6 days. We found that some males showed high site fidelity but very little activity, and territorial disputes were almost inexistent. Females, on the other hand, were rarely observed on the river, and were found mainly on the nearby paths and forest. We recorded 28 tandems and observed a total of 17 copulations, lasting an average of 18.6 min. Examination of sperm volumes in females interrupted during copulation indicated that males removed most of the sperm from the female bursa copulatrix during stage I of copula, but they could not remove sperm from the paired spermathecae. The duration of precopulatory tandem was highly variable (from 3 min to 7.8 h). In some cases, copulation was observed shortly (3 min) after tandem formation, mainly during the morning. However, some pairs formed during the morning, remained in tandem for several hours, and mated late, after dusk. Females laid eggs not accompanied by the male. Mating after the main peak of activity might be a strategy which protects sperm investment because females laying eggs after dusk are unlikely to be mated again that day. Further studies are needed to decipher phenotypic correlates of the males that mate after dusk.

У статті розглядаються основні проблеми реалізації компетентнісного підходу в сучасній освіті у підручниках для середньої школи Австрії. Проаналізовано сучасні європейські компетентності, запропоновані провідними європейськими політичними організаціями. З’ясовано, що система навчання у середній школі Австрії ґрунтується на компетентнісному підході до освіти, а компетентності поділяються на загальнонавчальні, предметні (фахові) та загальнопредметні (міжпредметні), які формуються у процесі вивчення того чи іншого предмету. Усі компетентності будуються навколо 4 головних тем: медійна, політична, мовна освіта та читання, економічна, фінансова та споживацька освіта. Проаналізовано основні положення нового навчального плану для середніх шкіл країни. Окремо визначено цілі компетентнісно-орієнтованого навчання іноземної мови. Проаналізовано шкільні підручники на предмет реалізації цього підходу.
Hacia una propuesta de rúbrica para la evaluación de la calidad de comentarios de código en Java.
Authors:   Universidad Autónoma de Zacatecas, Garcia Murillo Juan Carlos
Published: January 2024

En el desarrollo de software, la documentación desempeña un papel importante para conocer el origen, detalles, razón de ser, entre otros factores de un proyecto. Su utilidad es muy amplia y se extiende incluso como apoyo para que futuros desarrolladores puedan darle continuidad al sistema con menores dificultades. El código de un software es uno de los elementos más complejos de entender, ya que cada desarrollador posee una forma propia de programar. La manera por excelencia para hacer un código comprensible es acompañarlo de buenos comentarios: completos y consistentes. En este artículo proponemos una rúbrica para evaluar la calidad de los comentarios de código en Java. Dicha rúbrica está dividida por categorías según el tipo de comentario a evaluar: comentario de autoría, comentario de clase, comentario de método y comentario de fragmento de código. Cada categoría establece un conjunto de reglas que deben cumplirse para declarar que un comentario es de calidad. El aumento en la legibilidad y mantenibilidad del código en proyectos de software que se encuentran actualmente en uso, después de haber utilizado la rúbrica, nos ayudará a validar su efectividad. Una vez comprobada esta eficacia, ayudará a los equipos a poseer códigos correctamente comentados y a reducir costos en labores de entendimiento y mantenimiento del código, pues este será más legible y descriptivo.
