Material and method. A total of 120 samples were created and (divided into three groups each groups contain forty samples) built regarding the attitude test: Candida albicans adherence test, flexural strength test, and hardness test. Next, each group was subdivided into three subgroups (control 0%, 1%, 2% and 3%) based on the various quantities of the added natural coconut oil, with (n=10 samples for each subgroup). Each group was assessed at 48 hours. One-way ANOVA and other statistical methods were used to analyze the data, Duncan and Dunnett’s tests for comparison means among all groups with control at p ≤0.05. Results. A One-way ANOVA showed a significant difference in the mean values of Candida albicans adherence, with the additive of natural coconut oil groups (1%, 2%) showing the highest antifungal effect compare with (3% additive groups). Adding 1% coconut oil had no significant difference on hardness and flexural strength, while adding 2% and 3% additive of coconut oil groups showed a significantly decrease than control groups at p ≤ (0.05). Conclusion. The antifungal properties of heat-cured acrylic resin are enhanced by the addition of coconut oil. However, when used in high concentrations (greater than 1%), it can result in a decrease in hardness and flexural strength.

Published: June 2024

Porang plant tubers have the potential to have high economic value, because they contain glucomannan which is good for health and can be processed into a food source to replace carbohydrates. The aim of the study was to identify Karawang Local Porang strains using molecular markers and morphological characters as an effort to conserve and utilize Karawang's local biological resources. Exploration of Local Porang Karawang was carried out at the foot of Mount Sanggabuana which is the habitat of Porang in Karawang district. Molecular identification was carried out at BBPP Biotechnology and Agricultural Genetic Resources with comparisons of Porang Sidrat., Madiun 1 and SS1 Bulukumba varieties. Morphological identification was carried out at the Basic Laboratory of the Faculty of Agriculture, Winaya Mukti University. Based on the results of the DNA amplification of the Porang samples using four RAPD primers, it was found that the three primers showed differences in banding patterns between the Porang Karawang sample and the three Porang varieties for comparison (Porang Madiun 1 Sidrap and SS1 Bulukumba). This shows that there is genetic variation between Porang from Karawang and three other Porang. The results of genetic relationship analysis using four RAPD primers showed that the Porang Karawang sample was different from the Porang samples from the other two areas. The morphological identification results showed differences in characteristics with the comparison. The Karawang Local Porang variety has high quality as indicated by high glucomannan levels of 79.80%.

Published: June 2024

This research explores the impact of intercropping corn and soybean, along with the combined effects of Azolla pinnata dose, the best soybean variety, and cytokinin concentration, on enhancing the physiology and agronomy of the plants. The study was conducted using 36 experimental units in a plot between soybean and corn. Various parameters were observed, including seed viability and vigor, soil analysis, nutrient content analysis of POC Azolla pinnata, temperature, air humidity, sunlight radiation, rainfall, pest infestation, diseases, and weeds. Additionally, plant height, leaf count, secondary branch count, total plant dry weight, leaf chlorophyll, leaf area ratio, leaf chlorophyll index, and stomatal conductance were measured. The data were analyzed using Djajasukanta and Sitompul-Guritno calculations, focusing on the average relative growth rate (RGR), average net assimilation rate (NAR), and root-shoot ratio (RSR). The results demonstrated that intercropping corn and soybean with the combination of Azolla pinnata dose, the best soybean variety, and cytokinin concentration had a positive impact on soybean production and quality. The Anjasmoro variety showed favorable outcomes in various parameters, such as plant height, leaf count, and branch count. Physiological leaf analysis revealed that the treatment combination with the Anjasmoro variety exhibited optimal photosynthetic rates and chlorophyll content, indicating higher photosynthesis efficiency. Moreover, the treatment with the Dega 1 variety displayed faster growth and efficient resource allocation, as evident from the high RSR value. The selection of the best soybean variety, Azolla pinnata dose, and cytokinin concentration can lead to sustainable improvements in soybean crop yield. These findings hold significant implications for agricultural management and enhancing food security.

Published: June 2024

The Bill on Science and Technology Cooperation between Countries has been introduced in the National Assembly to establish a legal basis for establishing and promoting international joint research policies, such as conducting innovative basic research through free and diverse collaboration with researchers from around the world. The bill aims to provide the basic principles and directions for S&T cooperation between countries necessary to promote the development of domestic S&T and strengthen national competitiveness, and to lay the foundation for a strong S&T nation by activating S&T cooperation between countries.
Korea's growth has been achieved through a catch-up S&T system, and now it is time to transform into a leading S&T system, and international cooperation is a key factor for the transition to a leading system. Therefore, the purpose of the bill, which aims to solidify the legislative basis for promoting international cooperation in S&T, is of paramount importance.
Given the importance of the bill, it is highly likely that the government will take the initiative to propose it again. In order to improve the bill, this article examines the main contents of the current bill, complements it, and suggests additional contents to be included.
Study on Gender-Based Violence with a focus on international human rights norms: Centered on an analysis of the European Court of Human Rights case P. and S. v. Poland (2012)
Authors:   Legal Research Institute of Chonnam National University, Jun Hyungjoon , Lee Hyun Jung
Published: June 2024

Gender-Based Violence against women is one of the most prevalent problems in most countries around the world. The issue of gender-based violence against women is related to the principle of constitutional equality, which guarantees equal rights for men and women, and the principle of non-discrimination, which prohibits discrimination on the basis of gender. In particular, violence against women can be considered gender-based violence because it is often caused by structural discrimination that goes beyond the usual criminal case. The case analyzed in this paper, P. and S. v. Poland, decided by the European Court of Human Rights in 2012, is significant because it is a relatively recent decision that addresses constitutional issues related to gender-based violence: the right to abortion, the prohibition of torture, the right to liberty, the right to respect for private and family life, the right to a fair-trial, the right to freedom of thought, conscience, and religion, and the principle of non-discrimination. The ECtHR found that the State's actions in relation to the applicant P. in this case fell short of the minimum measures required by Article 3 of the European Convention on Human Rights and that she had been subjected to inhuman and degrading treatment. It also found that the deprivation of liberty by separating her from her parents and placing her in an institution was incompatible with Article 5 § 1 of the ECHR. The ECtHR also found that information concerning the sensitive private life of P. and her mother S. had been disclosed and that this disclosure could not be legally justified, thus concluding that Poland had violated Article 8 of the ECHR, as alleged by the applicants. However, no finding was made as to whether P. and S.'s negative freedom of religion could have been substantially violated in this case. In conclusion, it can be seen that, despite various efforts, the obligations to protect women from violence in family and social life are not adequately fulfilled by law. This is not a problem unique to Poland. In many countries, there is still a gap between traditional values and laws. It is hoped that this ruling will bring about a shift in the perception of gender-based violence.
A Study on the Rights of Nature to Preserve Sustainable Natural Ecosystems
Authors:   Legal Research Institute of Chonnam National University, Choi jinyi
Published: June 2024

The Civil Law limits the qualifications to have legal personality to ‘persons (natural persons or corporations).’ However, since the 1970s, the opinion that there is a need to extend the legal qualifications for rights subjects, which are limited to humans, to include nature or natural components has emerged as a major concern in law. This is a discussion about the so-called rights of nature.
A representative recent example is the Republic of Ecuador. In September 2008, Ecuador revised its constitution and established a new regulation recognizing the rights of nature, thereby providing a constitutional basis for nature to protect its own right to survival. Meanwhile, Republic of Bolivia became the first country to recognize the rights of nature in law by enacting a law declaratively defining universal rights to the rights of nature in December 2010. And Republic of Colombia does not have provisions on natural rights in its constitution. However, the Constitutional Court and the Supreme Court recognize the existence of natural rights by actively interpreting environmental rights and the relationship between nature and humans from the perspective of ecocentrism.
Article 35 of the Constitution of the Republic of Korea also provides for environmental rights. However, this is not intended to recognize nature as a subject of rights, or to protect the intrinsic value of nature itself or the ecosystem. Nature and its components are recognized only as tools for human benefit. However, with this human-centered view of nature, it is impossible to fundamentally resolve today's natural destruction and the resulting climate crisis. Therefore, in order to ensure a sustainable natural ecosystem for future generations, theoretical attempts are underway to grant a certain legal status to non-human nature or natural objects.
In this paper, I reviewed the concept of the rights of natural objects other than humans or nature itself among the subjects of nature, as well as domestic discussions and major overseas cases regarding natural rights. And a plan for domestic acceptance of natural rights was sought.

Published: May 2024

The application of machine learning algorithms has become widespread particularly in fields such as medicine, business, and commerce. However, achieving accurate classification results with these algorithms often relies on large-scale training datasets, making data collection a lengthy and complex process. This paper reviews the current utilization of generative adversarial network (GAN) architectures and discusses recent scientific research on their practical applications. The study emphasizes the significance of addressing data scarcity in the process of training the machine learning algorithms and highlights the potential of advanced GAN architectures, in particular StyleGAN2-ADA, to mitigate this challenge. The findings contribute to ongoing efforts aimed at enhancing the efficiency and applicability of artificial intelligence across diverse domains by presenting a viable solution to the constraint of limited training data for image classification tasks.
LARGE-SCALE EMERGENCY SUPPLIER SELECTION CONSIDERING LIMITED RATIONAL BEHAVIORS OF DECISION MAKERS AND RANKING ROBUSTNESS
Authors: Li Xiaofang , Liao Huchang , Baušys Romualdas , Zavadskas Edmundas Kazimieras
Published: May 2024

Selecting emergency suppliers from a wide range of candidates based on their performance under each criterion can be regarded as a multi-criterion decision making (MCDM) problem. Existing MCDM models to solve the emergency supplier selection problem ignored situations where large-scale suppliers exist, the influence of criteria weights on the robustness of ranking results, and the influence of psychology of regret aversion and disappointment aversion on decision results. To make up for these deficiencies, this paper proposes an MCDM model to solve emergency supplier selection problem with large-scale alternatives. Firstly, to avoid the influence of criteria weights on ranking of alternatives, the Robustness, Correlation, and Standard Deviation (ROCOSD) method is introduced to determine objective weights of criteria based on three objectives. Secondly, the τ-balanced clustering method is applied to cluster large-scale alternatives into balanced clusters. Next, considering the psychology of regret aversion and disappointment aversion of decision makers, a two-stage method is proposed to rank alternatives, which identifies the optimal alternative within each cluster and forms a new cluster consisting of these optimal alternatives in the first stage, and selects the optimal alternative from the new-formed cluster in the second stage. A numerical case is given to validate the proposed model.
Are High-Σ1 Massive Blue Spiral Galaxies Rejuvenated Systems?
Authors: Hao Cai-Na , Xia Xiaoyang , Shi Yong , Guo Rui , Chen Yanmei , Feng Shuai , Ge Junqiang , Gu Qiusheng
Published: June 2024

Quiescent galaxies generally possess denser cores than star-forming galaxies with similar mass. As a measurement of the core density, the central stellar mass surface density within a radius of 1 kpc (Σ1) was thus suggested to be closely related to galaxy quenching. Massive star-forming galaxies with high Σ1 do not fit into this picture. To understand the origin of such galaxies, we compare the spatially resolved stellar population and star formation properties of massive (>1010.5
M
⊙) blue spiral galaxies with high and low Σ1, divided by Σ1 = 109.4
M
⊙ kpc−2, based on the final release of MaNGA integral field unit data. We find that both high-Σ1 and low-Σ1 blue spirals show large diversities in stellar population and star formation properties. Despite the diversities, high-Σ1 blue spirals are statistically different from the low-Σ1 ones. Specifically, the radial profiles of the luminosity-weighted age and Mgb/〈Fe〉 show that high-Σ1 blue spirals consist of a larger fraction of galaxies with younger and less α-element-enhanced centers than their low-Σ1 counterparts, ∼55% versus ∼30%. The galaxies with younger centers mostly have higher central specific star formation rates, which still follow the spaxel-based star formation main-sequence relation. Examinations of the Hα velocity field and the optical structures suggest that galactic bars or galaxy interactions should be responsible for the rejuvenation of these galaxies. The remaining ∼45% of high-Σ1 blue spirals are consistent with the inside-out growth scenario.

Published: May 2024

Oat (Oa) and apple (Ap) starches were isolated and chemically modified by oxidation with 10% NaOCl to obtain oxidized starches (OOa and OAp), followed by cross-linking with a mixture of 5.6 g of sodium tripolyphosphate and 11 g of sodium trimetaphosphate to obtain doubly modified starches (OCOa and OCAp). In the native and modified starches, the functional properties (swelling power and solubility, and freeze-thaw stability) and thermal and rheological properties (steady-state flow curves and paste formation profile) were evaluated. The swelling power of native and double modified starches varied from 57 to 86 g/g and the solubility from 0.8 to 6.0 g/100 g, these variables increased as the study temperature increased; the increment in these properties was greater in Oa compared to Ap. Oxidation followed by crosslinking increased the freeze-thaw stability in Oa and Ap starches at 30, 60, 75, and 90 °C. It also increased the Tg of OCAp and OCOa ≈ 9% compared to the native samples, respectively; while an inverse pattern was observed in apparent viscosity were this value decreased ≈ 0.8 Pa × s for Oa and ≈ 0.5 Pa × s for Ap compared to the double modified samples. All samples presented a thinning cut-type behavior (pseudoplastic), indicating structural differences. Cross-linking in oxidized starches produced a reinforcing matrix that was determined in the paste formation profile. Dual modification (oxidation-cross-linking) could be an alternative for using starches from underused botanical sources, such as apples and oats, with different functional properties and feasible applications in food systems.

Museum collections are an important source for resolving taxonomic issues and species delimitation. Type specimens as name-bearing specimens, traditionally used in morphology-based taxonomy, are, due to the progress in historical DNA methodology, increasingly used in molecular taxonomic studies. Museum collections are subject to constant deterioration and major disasters. The digitisation of collections offers a partial solution to these problems and makes museum collections more accessible to the wider scientific community. The Extended Specimen Approach (ESA) is a method of digitisation that goes beyond the physical specimen to include the historical information stored in the collection. The collections of the Natural History Museum Vienna represent one of the largest non-university research centres in Europe and, due to their size and numerous type specimens, are frequently used for taxonomic studies by visiting and resident scientists. Recently, a version of ESA was presented in the common catalogue of the Fish and Evertebrata Varia collections and extended to include genetic information on type specimens in a case study of a torpedo ray. Here the case study was extended to a heterogeneous selection of historical type series from different collections with the type locality of Vienna. The goal was to apply the ESA, including genetic data on a selected set of type material: three parasitic worms, three myriapods, two insects, twelve fishes, and one bird species. Five hundred digital items (photographs, X-rays, scans) were produced, and genetic analysis was successful in eleven of the 21 type series. In one case a complete mitochondrial genome was assembled, and in another case ten short fragments (100–230 bp) of the cytochrome oxidase I gene were amplified and sequenced. For five type series, genetic analysis confirmed their taxonomic status as previously recognised synonyms, and for one the analysis supported its status as a distinct species. For two species, genetic information was provided for the first time. This catalogue thus demonstrates the usefulness of ESA in providing digitised data of types that can be easily made available to scientists worldwide for further study.
A new filled function method based on global search for solving unconstrained optimization problems

The filled function method is a deterministic algorithm for finding a global minimizer of global optimization problems, and its effectiveness is closely related to the form of the constructed filled function. Currently, the filled functions mainly have three drawbacks in form, namely, parameter adjustment and control (if any), inclusion of exponential or logarithmic functions, and properties that are discontinuous and non-differentiable. In order to overcome these limitations, this paper proposed a parameter-free filled function that does not include exponential or logarithmic functions and is continuous and differentiable. Based on the new filled function, a filled function method for solving unconstrained global optimization problems was designed. The algorithm selected points in the feasible domain that were far from the global minimum point as initial points, and improved the setting of the step size in the stage of minimizing the filled function to enhance the algorithm's global optimization capability. In addition, tests were conducted on 14 benchmark functions and compared with existing filled function algorithms. The numerical experimental results showed that the new algorithm proposed in this paper was feasible and effective.
On an asymmetric multivariate stochastic difference volatility: structure and estimation
Authors: Alzeley Omar , Ghezal Ahmed
Published: June 2024

In this study, we explored an asymmetric multivariate stochastic difference volatility model that extends various probabilistic and statistical properties previously discussed in the literature. We rigorously established that the model exhibits periodic stationarity and periodic ergodicity. Additionally, we delved into the robust consistency and asymptotic normality of the Quasi-Maximum Likelihood Estimator (QMLE), providing a comprehensive analysis of its theoretical underpinnings. Finally, we demonstrated the practical applicability of our major findings through a series of pertinent applications. This work not only contributes to the existing body of knowledge on stochastic volatility modeling, but also opens new avenues for further research in this domain.
Predicting the transmission trends of COVID-19: an interpretable machine learning approach based on daily, death, and imported cases
Authors: Ahn Hyeonjeong , Lee Hyojung
Published: June 2024

COVID-19 is caused by the SARS-CoV-2 virus, which has produced variants and increasing concerns about a potential resurgence since the pandemic outbreak in 2019. Predicting infectious disease outbreaks is crucial for effective prevention and control. This study aims to predict the transmission patterns of COVID-19 using machine learning, such as support vector machine, random forest, and XGBoost, using confirmed cases, death cases, and imported cases, respectively. The study categorizes the transmission trends into the three groups: L0 (decrease), L1 (maintain), and L2 (increase). We develop the risk index function to quantify changes in the transmission trends, which is applied to the classification of machine learning. A high accuracy is achieved when estimating the transmission trends for the confirmed cases (91.5–95.5%), death cases (85.6–91.8%), and imported cases (77.7–89.4%). Notably, the confirmed cases exhibit a higher level of accuracy compared to the data on the deaths and imported cases. L2 predictions outperformed L0 and L1 in all cases. Predicting L2 is important because it can lead to new outbreaks. Thus, this robust L2 prediction is crucial for the timely implementation of control policies for the management of transmission dynamics.
An anti-impersonation attack electronic health record sharing scheme based on proxy re-encryption and blockchain

Many current electronic medical record (EMR) sharing schemes that use proxy re-encryption and blockchain do not fully consider the potential threat of malicious node impersonation attacks. This oversight could lead to data leakage as attackers masquerade as legitimate users or proxy nodes during the sharing process. To deal with this problem, we propose an EMR sharing scheme based on proxy re-encryption and blockchain to protect against impersonation attacks. First, we prevent the potential threat of impersonation attacks by generating a shared temporary key and assigning tasks to multiple proxy nodes. Second, we use a random function to ensure that the selection of encrypted proxy nodes is fair. Third, we use a combination of blockchain and the InterPlanetary File System to solve the problem of insufficient storage capacity of shared processes and ensure the storage security of EMRs. Through the security proof, our scheme guarantees anti-impersonation, anti-collusion, and anti-chosen plaintext attack capability in the sharing process of EMRs. Additionally, experiments on the blockchain platform, namely Chain33, show that our scheme significantly increases efficiency.
Les musiciens d’Église en Bretagne en 1790
Authors: Carbonnier Youri
Published: June 2024

La base prosopographique Muséfrem, consacrée aux musiciens d’Église actifs en France à la fin de l’Ancien Régime, présente la biographie de 323 individus en Bretagne en 1790. Parmi eux, 224 sont réellement des musiciens, ne se cantonnant pas au plain-chant. La plupart sont originaires de Bretagne, mais un gros quart vient d’autres régions. Certains parcourent de longues distances, inscrivant la Bretagne dans un parcours professionnel complexe, au sein duquel l’attrait salarial joue sans doute un rôle non négligeable. Les femmes musiciennes (toutes organistes) sont, comme ailleurs, très minoritaires et sont nées en Bretagne. Organistes et enfants de chœur constituent les deux fonctions les plus nombreuses, suivies par les musiciens ou chanteurs, puis les instrumentistes. L’un des caractères particulièrement marquants de la Bretagne est l’importance de la place des organistes, qui ne se retrouve guère ailleurs.
Les paroisses rurales bretonnes : quelles réalités musicales ?
Authors: Provost Georges
Published: June 2024

Dans la continuité des travaux d’inventaire et de recherche sur les orgues menés depuis les années 1980, la présente communication vise à préciser ce qu’il est possible de connaître des pratiques musicales dans les églises des campagnes bretonnes aux Temps modernes. La rareté comme la dispersion des informations dans les archives ont conduit à privilégier deux territoires d’enquête : les actuels départements du Finistère et d’Ille-et-Vilaine, retenus respectivement pour la richesse de ses paroisses et la qualité du classement de ses archives. Les données réunies, croisées avec les témoignages matériels (orgues, lutrins, stalles, livres de chœur) permettent de tenter une approche globale de l’orgue et de ses usages en Bretagne rurale (commanditaires, facteurs, organistes). Archives et objets permettent également d’aborder la question, largement méconnue en Bretagne, du plain-chant paroissial et de ses conditions d’exercice en milieu rural (lieux, acteurs). À titre d’hypothèse, il semble possible d’avancer que la forte densité du clergé en Bretagne et la faible alphabétisation ont retardé l’émergence de la figure du chantre laïc, qui n’apparaît guère avant la Révolution.
Le manuscrit musical Rés. 1474 de la BNF : un répertoire pour la cathédrale Saint-Pierre de Vannes ou pour les couvents d’alentour ?
Authors: Duron Jean
Published: June 2024

Le recueil manuscrit Rés. 1474 de la Bibliothèque nationale de France (département de la Musique) est l’un des très rares et précieux témoignages de la musique religieuse en France sous l’Ancien Régime. Ses 430 pages de musique ont été copiées par Claude-Alexis Le Maignan de Kerangat, sous-chantre de la cathédrale de Vannes entre 1708 et 1711. Le recueil rassemble 73 motets dont 50 (les 2/3) sont attribués à Daniel Danielis, maître de musique de la cathédrale de 1684 à 1696 et l’une des figures les plus importantes de la musique religieuse en France sous le règne de Louis XIV. Ce recueil qui semble très homogène, n’est pas sans poser un certain nombre de questions. Certaines touchent les autres compositeurs de ce recueil, pour quelques-uns attachés un temps à la cathédrale. D’autres comme Campra et Brossard, célèbres à Paris dès les années 1695-1700, sont représentés parfois avec des motets inédits qui ont donc pu être chantés à Vannes. Mais la question la plus ardue est certainement celle de la destination de ce répertoire, réservé exclusivement à de petites formations musicales sans rapport avec les effectifs musicaux de la cathédrale.
