No ensino de Química, a compreensão dos fenômenos de luz e cor são fundamentais para o desenvolvimento de conceitos mais avançados, como a espectroscopia e as interações entre radiação e matéria. Entre os diversos fenômenos ópticos, as cores aditivas, provenientes da radiação solar, têm como cores primárias o vermelho, o verde e o azul. São conhecidas por essa nomenclatura porque a sobreposição de duas destas gera outras, conhecidas como cores secundárias, o modelo de cores aditivas mais conhecido é o RGB, que vem do inglês que significa “red, green e blue”. Esse modelo está bastante presente nas telas de computadores, celulares e televisão. No cinema, por exemplo, a combinação das cores aditivas é usada para criar cenas vibrantes, com uma vasta gama de tonalidades, gerando uma conexão direta entre os conceitos científicos e sua aplicação no entretenimento. O filme utilizado para abordar tonalidades aditivas foi intitulado como "As duas faces da felicidade" ou “Le bonheur”, que é um filme estrangeiro produzido por Agnès Varda. Na obra, a diretora emprega cores opostas, como o vermelho e azul, para representar dois mundos distintos. Desta forma, o presente trabalho contextualiza os aspectos cinematográficos do filme com os conteúdo relacionados às ondas eletromagnéticas e à luz, proporcionando uma visão Química dos fenômenos envolvidos. A metodologia utilizada foi de cunho qualitativa e participante. A palestra intitulada “Estudo Químico das Cores Aditivas por Meio de uma Análise Cinematográfica” foi ofertada pelo Programa de Educação Tutorial - PET Química, para os estudantes do curso de Licenciatura em Química do Instituto Federal da Paraíba - IFPB, Campus João Pessoa. A atividade aconteceu de forma remota, no período da manhã e foi dividida em três momentos. O primeiro momento sucedeu-se na aplicação de um Questionário de Sondagem (QS) que continha 6 (seis) perguntas, nas quais indagavam sobre os conhecimentos prévios dos alunos inerente a temática. No segundo momento, houve a apresentação da palestra e no terceiro momento foi aplicado o questionário final (QF) que continha 5 (cinco) questões, as quais proferiam realizar um apanhado sobre os conhecimentos adquiridos durante a palestra. Os resultados obtidos demonstraram que a interdisciplinaridade realizada entre Química e o Cinema pôde contribuir de forma significativa na aprendizagem dos alunos por meio da temática abordada. Ressalta-se também, que é de suma importância o uso de tecnologias contemporâneas para o ensino da Ciência.

Penelitian  ini merupakan penelitian hukum dengan spesifikasi yang bersifat deskriptif analitis. Bentuk pengawasan internal oleh Inspektorat Pengawasan Daerah Kepolisian Daerah Sumatera Barat terhadap penyelesaian tindak pidana secara restoratif  adalah memastikan bahwa proses tersebut dijalankan dengan transparansi, profesionalisme, dan sesuai dengan ketentuan hukum yang berlaku. Pengawasan ini mencakup aspek syarat tindak pidana yang dapat direstoratif justice. Memastikan bahwa pelaku, korban, dan masyarakat (terutama keluarga) setuju. Pengawasan ini dilakukan untuk mencegah terjadinya penyimpangan seperti Itwasda bertugas mengawasi agar anggota kepolisian tidak menyalahgunakan posisinya untuk memaksakan atau memanipulasi hasil dari proses restorative justice. Penyimpangan yang harus dihindari adalah adanya dugaan pemerasan atau sogokan dari pelaku untuk menghindari proses peradilan formal. Itwasda memantau implementasi dari kesepakatan yang disepakati. Kendala dalam  pengawasan internal oleh Inspektorat Pengawasan Daerah Kepolisian Daerah Sumatera Barat terhadap penyelesaian tindak pidana secara restoratif  adalah tidak adanya standarisasi proses, tanpa aturan yang jelas, standar pengukuran kinerja yang tidak seragam. Kesulitan dalam memastikan bahwa proses mediasi dan penyelesaian dilakukan dengan benar dan adil. Proses restorative justice hanya menjadi prosedur administratif tanpa memperhatikan prinsip pemulihan yang sesungguhnya, sehingga proses tidak memberikan hasil yang diharapkan oleh semua pihak yang terlibat. Keterbatasan sumber daya, baik dari segi jumlah personel pengawas maupun dukungan teknologi untuk melakukan monitoring secara berkala terhadap penyelesaian tindak pidana melalui restorative justice.

Published: February 2025

Tabular data synthesis is crucial in machine learning, yet existing general methods-primarily based on statistical or deep learning models-are highly data-dependent and often fall short in recommender systems. This limitation arises from their difficulty in capturing complex distributions and understanding complicated feature relations from sparse and limited data, along with their inability to grasp semantic feature relations. Recently, Large Language Models (LLMs) have shown potential in generating synthetic data through few-shot learning and semantic understanding. However, they often suffer from inconsistent distribution and lack of diversity due to their inherent distribution disparity with the target dataset. To address these challenges and enhance tabular data synthesis for recommendation tasks, we propose a novel two-stage framework named SampleLLM to improve the quality of LLM-based tabular data synthesis for recommendations by ensuring better distribution alignment. In the first stage, SampleLLM employs LLMs with Chain-of-Thought prompts and diverse exemplars to generate data that closely aligns with the target dataset distribution, even when input samples are limited. The second stage uses an advanced feature attribution-based importance sampling method to refine feature relationships within the synthetic data, reducing any distribution biases introduced by the LLM. Experimental results on three recommendation datasets, two general datasets, and online deployment illustrate that SampleLLM significantly surpasses existing methods for recommendation tasks and holds promise for a broader range of tabular data scenarios.

Published: February 2025

Background

Children are generally attracted to colorful foods. However, some food dyes are suspected of exacerbating the activity of children and inducing other health problems that can reach reprotoxicity and carcinogenicity.

Objective

This study aims to explore the presence of dyes such as E102, E104, E110, E121, E122, E123, E124, E127, E129, E132, E133, E143 and E171 in food products widely consumed by children in Algeria notably sweets and chocolates, beverages and ice creams, yogurts and biscuits.

Material and Methods

This work was carried out on 228 products including 57 biscuits, 47 drinks and ice creams,
20 yogurts and 104 sweets and chocolates. Information mentioned on the composition label of this products were recorded to determine the presence of studied dyes

Results

Here, we report the abundance of the yellow dyes E102 (24.1%) and E110 (18%) in the tested products. Also, apart from E121, all the other assessed dyes were found. Sweets and chocolates are the products containing the most studied dyes. The analysis of the presence of combinations of these dyes shows that 7% of analyzed foods contain 2 dyes in their composition while 20% of the products contain at least 3 dyes at the same time. Additionally, 37.5% of sweets and chocolates contain a combination of at least 3 dyes in their ingredient list.

Conclusions

In overall, except the E121, all assessed dyes were identified on the labels of food products widely consumed by children which encourage parents to be made aware of the risks associated with the ingestion of omnipresent dyes in children’s diets.

Published: February 2025

The conversion of the Amazon rainforest into pasture significantly impacts soil quality, affecting biodiversity, biogeochemical cycles, and carbon stocks. Studies indicate a reduction in microbial activity and biomass associated with this transformation. This study investigated the impact of converting forest into pasture on soil attributes in the northern Amazon, specifically at the Canto Verde farm in Iracema, Roraima, Brazil. Three land use systems were analyzed: Native Forest (NF), Brachiaria brizantha (BB), and Brachiaria humidicola (BH). Soil samples were collected at two depths (0-0.10 m and 0.10-0.20 m) in four representative blocks of 1 ha in each system. Chemical, physical, and biochemical properties, and microbial and metabolic coefficients were analyzed. The results were subjected to analysis of variance and the Tukey test (p<0.05). The transition from NF to agricultural use with Brachiaria significantly altered soil attributes. There was an increase in pH in the BB and BH systems and a reduction in total organic carbon and microbial biomass. Basal respiration and dehydrogenase activity decreased, indicating stress in the transformed systems. The BH system showed higher metabolic quotient (qCO2) and lower microbial quotient (qMIC) values, highlighting the adverse effects of converting forests into pastures on soil microbiological activity. The conversion of forests into pastures negatively affects the soil, requiring sustainable agricultural practices.
A Study on the Legislative Process and Systems of U.S. State Legislatures from the Policy Formation Perspective
Authors:   The Korean Association For Local Administration, Hong Sung-Woo
Published: February 2025

The purpose of this study is to explore policy and practical implications by analyzing the systems and policy cases related to the legislative process of the U.S. state legislature from the perspective of policy formation. The causes of policy failures in the policy formation process are diverse, but designing better management of processes and systems related to the policy formation process (legislative process) would be an alternative strategy to reduce such policy failures. From this perspective, I briefly reviewed the overall structure and institutions of U.S. state legislatures. As a case study, I analyzed the legislative procedures and systems as well as specific legislative cases focused on the Texas House of Representatives.
The main policy implications from the perspective of designing and managing the system to reduce policy failures in the policy formation process are as follows: First, it is necessary to consider designing a system that allows for continuous bill analysis that reflect amendments made during the deliberation process, as well as cost estimation and legislative impact assessment for bills in specific fields. Second, it would be worth considering designing a calendars system that divides bills submitted to the plenary session into broad and controversial bills and narrow and non-controversial bills based on content, importance, and influence. In order to design and operate such systems, securing a professional support institution and personnel would be prioritized.
The Impact of Public Service Values on Occupational Satisfaction in the Public Sector : Focusing on the Mediating Role of Public Service Motivation
Authors:   The Korean Association For Local Administration, Han Won-Geun , Ryu Geunpil
Published: February 2025

A wealth of prior research has examined the link between public service values and job satisfaction. This study, however, seeks to investigate this relationship through the lens of person-organization fit theory, specifically focusing on occupational satisfaction within the public sector. Moreover, it aims to reveal the mechanisms underlying the relationship between public service values and public-sector occupational satisfaction, employing the concept of public service motivation—a motivational framework unique to public administration. This study thus poses two central research questions: (1) Do public service values positively influence public-sector occupational satisfaction? and (2) Does public service motivation mediate the relationship between public service values and the satisfaction in the public sector? To address these questions, data from the 2023 Public Employee Survey by the Korea Institute of Public Administration were analyzed using structural equation modeling to test the proposed hypotheses. The findings confirmed that public service values have a statistically significant positive effect on public-sector occupational satisfaction. Furthermore, public service motivation was found to fully mediate the relationship between public service values and public-sector occupational satisfaction.

Published: February 2025

The objective of this study is to evaluate the efficiency of boiler machine performance at PT Wilmar Nabati Indonesia through the application of the Input-Output method and Failure Mode and Effect Analysis (FMEA). The input-output method is employed to calculate the efficiency of boiler performance, based on fuel consumption data and steam production flow. Meanwhile, FMEA was employed to identify and evaluate potential failures in various boiler equipment and to ascertain the severity, recurrence, and detection values associated with operational risks. The findings revealed a notable decline in boiler machine efficiency, with some days exhibiting values below the critical threshold of 76.22%. This decline is indicated by various factors, including poor fuel quality, temperature and pressure setting errors, and potential damage to boiler components. In order to address these issues, this study recommends a thorough audit of the boiler system, the implementation of stricter monitoring procedures, and the development of a boiler machine maintenance plan. With a better understanding of the factors affecting efficiency, it is hoped that the company can improve the performance of the boiler machine and prevent further damage.
How Human Exploitation May Be Fought in Public Procurement-Affected Industries?
Authors: Gellén Márton
Published: February 2025

Human exploitation is a global phenomenon despite being globally fought against. The exact number of people in modern enslavement remains unknown but the tendency is obvious. Counterintuitively, even Covid–19 policies seem to have contributed to the level of exploitation through supply shortages and increased demand for commodities and low-added-value goods. The article discusses the inevitable necessity that governments step up against all forms of human exploitation domestically so as in global supply chains. The article intends to stir up attention against the position that the U.S. Federal Acquisition Regulation, the UK Modern Slavery act, let alone the EU’s Public Procurement Directive could not be improved significantly. The article scrutinises these legislative items through the lens of their efficacy. The article finds that all three regulatory regimes have their specific imperfections: the U.S. law does not pay significant attention to the notion of reparation, the UK law outsources the problem to the corporates while the EU Directive does not even reflect on the triviality that supply chains are globally interlinked, let alone paying attention to the time dimension and legal limitations of criminal proceedings. Furthermore, all three regimes apply the notion of commercial-off-the-shelf (COTS) products the public procurement of which are not under the anti-TIP regulations despite the apparent realities.

Background: Despite extensive research on the diseases of the reproductive system (testis and epididymis) in dogs, the extent of reproductive complications is unknown.
Objectives: The purpose of the present study was to evaluate the clinical, macroscopic, and histopathological findings of testicular and epididymal tissues in dogs of Ahvaz County, Khuzestan Province, Iran.
Methods: In the present study, 77 castrated testes were evaluated in different animal ages (from 7 months until 12 years). After macroscopic evaluation, the testicle and epididymis tissues were placed in 10% buffered formalin and processed.
Results: Sixty-eight cases of dogs had testicles with normal appearance. Four cases of dogs had cryptorchidism, which was determined during clinical examination. In five cases, the epididymis was swollen with dilated spaces. The microscopic study of the samples showed the presence of various lesions in 45 cases (58.44%). Four (8.89%) of 45 samples with lesions had unilateral cryptorchidism. Testicular degeneration was among the most important cases observed in 14(31.11%). Twenty-two (48.89%) out of 45 samples with lesions had epididymitis. Severe hyperplasia of the mucous membrane covering the epididymis was observed in these samples. Epididymitis and degeneration were observed in 12 cases simultaneously. Two cases of chronic epididymitis were associated with bleeding. Another finding was the observation of intranuclear and intracytoplasmic inclusions (in 29 cases). In 21 cases, epididymitis was also visible simultaneously, determined by the presence of fibrosis around the ducts and mucous hyperplasia. Bleeding was seen in 5 cases (11.11%).
Conclusion: Considering the relatively high prevalence of testicular degeneration, epididymitis, and the presence of inclusions in the studied dogs, castration in males and histopathological evaluations are very important for a definitive diagnosis of complications because they can lead to infertility, especially in purebred dogs that are kept in shelters (because of the chronic course of some infectious diseases).

Background: Invasive diseases cause severe illnesses in birds, which become extensive and threatening under conditions of general waterfowl breeding.
Objectives: The study aims to investigate the ecological peculiarities of the distribution of parasitocenoses of waterfowl.
Methods: Helminthovoscopic method (Fülleborn method) was used in the research. Also, we used the incomplete helminthologic autopsy method according to K.I. Skryabin.
Results: It was found that the prevalence of parasitocenosis of waterfowl in the forest-steppe zone was 76.7%, in the steppe zone 54.5%, and in the mountain-forest zone 36.7%. At low infestation intensity, the reproductive capacity of Echinostoma increases.
Conclusion: Parasitocenoses in waterfowl are caused by several species, including Echinostoma revolutum, Hypodereum conoideum, and Echinoparyphium recurvatum. These parasites can cause various waterfowl diseases, including intestinal disorders, loss of appetite and weight, and decreased productivity. Mixed infestation is quite common in which waterfowl are simultaneously infected with two or more intestinal parasites. In our study, the intensity of mixed infestation in geese with a combination of E. revolutum and H. conoideum species amounted to 36%.

Background: Heavy metals are non-degradable pollutants, and mercury is one of them. It can harm fish and reduce its growth rate. One of the most effective ways to reduce the side effects of heavy metals is to use herbal compounds or their active ingredients. Thymol is a natural monoterpene in plants’ essential oils, such as thyme. The positive effects of this substance have been proven to improve growth indicators in some fish, such as grass carp.
Objectives: This research was conducted to investigate the protective effects of thymol on the growth factors of juvenile carp exposed to mercury.
Methods: In the present study, 120 common carp (Cyprinus carpio) were randomly divided into 4 groups (control, HgCl2, thymol, and thymol+HgCl2). Each group was replicated three times and included 10 fish. At first, the initial weight of the fish (W0) was recorded, and then the fish were kept for 56 days. The control group fish were fed basic food and kept in mercury (II) chloride-free water. During 56 days, the fish of the thymol and thymol+HgCl2 groups were fed with food containing thymol 100 mg/kg feed. The tank water of the fish of the thymol+HgCl2 and HgCl2 groups contained 0.44 mg/L mercury chloride. After 56 days, the final weight (Wt) of the fish was also measured, and the growth factors (absolute growth, absolute growth rate, specific growth rate [SGR], food conversion ratio [FCR], and food conversion efficiency [FCE]) were calculated.
Results: This research showed that thymol has a protective effect on growth factors following chronic mercury exposure. Thymol in the thymol+HgCl2 group significantly improved absolute growth, absolute growth rate, and FCR compared to the HgCl2 group. Also, thymol significantly improved SGR and FCE factors, although there was no significant difference with the mercury group.
Conclusion: Thymol can effectively reduce the side effects caused by mercury chloride exposure in common carp.

Published: February 2025

The distance existed due to the COVID-19 pandemic drove people to utilize collaboration tools to continue communication, coordination, and collaboration. The increasing use of collaboration tools during WFH impact on our way of working. The collaboration tools also offer efficiencies, allow workers to break silos, and increase the quality of communication at the company-wide level. As we recover from the pandemic, the government revoked the social distancing policy and it is assumed to influence the continued use of collaboration tools as people fully carry out their activities face-to-face again. This study aims to understand the continuance usage of collaboration tools after no more social distancing. This study also seeks to identify the factors influencing the ongoing use of collaboration tools by integrating the Technology Acceptance Model (TAM) and Expectation Confirmatory Model (ECM). The method of data analysis employed was the partial least squares structural equation model (PLS-SEM). The findings indicated that most of 437 respondents kept using collaboration tools after no more social distancing. However, there was a decrease in the frequency of use. Our study findings have also proved that Actual Continued Usage is influenced by Continuance Intention by 43%. Factor that influences continuance intention the most is the attitude toward using collaboration tools, which is influenced by users’ perceived usefulness of the collaboration tools. The results of this study also support the integration of TAM and ECM to examine user intentions and behavior regarding the continuance use of a technology.
Feature Extraction using Histogram of Oriented Gradients and Moments with Random Forest Classification for Batik Pattern Detection
Authors: Wafiq azizah  , Soffiana agustin
Published: February 2025

The preservation of traditional batik patterns, often transmitted orally and through direct practice across generations, faces significant challenges in the modern era. Globalization introduces the risk of cultural homogenization, potentially diminishing the uniqueness and diversity of these patterns. Furthermore, the manual recognition of batik motifs is labor-intensive, time-consuming, and requires specialized expertise, rendering it unsuitable for large-scale preservation initiatives. Consequently, the development of technology-based solutions capable of documenting, analyzing, and recognizing batik patterns with efficiency and precision is imperative for safeguarding this cultural heritage. This study aims to address these challenges by developing an automated system for recognizing batik patterns, focusing on Javanese batik motifs—Kawung, Megamendung, and Parang—which serve as foundational designs for the evolution of batik in other regions. The proposed methodology integrates two feature extraction techniques, Histogram of Oriented Gradients (HOG) and Texture Moments, with the Random Forest machine learning algorithm. The research process encompasses four key stages: pre-processing, feature extraction, classification, and system evaluation, where the accuracy of individual and combined feature extraction methods is analyzed. Experimental results reveal that the HOG method achieves an accuracy of 78.99%, while the Texture Moments method yields 81.88%. Notably, the combination of these two methods enhances system performance, achieving the highest accuracy of 86.23%, representing a 4.65% improvement over the single methods. These findings underscore the efficacy of integrating HOG and Texture Moments with the Random Forest algorithm for automated batik pattern recognition.

This research aims to analyze and understand how the response quality of each chatbot in e-commerce platforms such as Shopee, Tokopedia, and Lazada affects e-commerce user satisfaction. This study employs a quantitative methodology, integrating data analysis conducted through the SmartPLS 4.1 software. The research results show that the chatbot in Shopee platform has a impact on customer satisfaction. The same goes for chatbot in Tokopedia platform, but there are two variables that do not have a direct impact, there are information quality and waiting time. Meanwhile, chatbot in Lazada platform does not affect customer satisfaction. The findings of this research should reveal new strategies for leveraging chatbot technology to better satisfy customers in e-commerce environments, as well as lay the groundwork for further research on how artificial intelligence can shape customer experiences in the future.

Published: February 2025

Предметом дослідження є теоретичні положення та існуючі підходи до формування механізму інвестування стартапів. Метою статті є сформувати організаційно-економічний механізм інвестування стартапів на основі критичного аналізу сучасних поглядів та розгляду його сутності.. У статті показано Основним завданням формування механізму управління є визначення його мети, об'єкта та суб'єкта. Метою інвестування з точки зору стартапів є забезпечення фінансових ресурсів для розвитку та росту підприємства на перших етапах його існування. Суб'єктами діяльності щодо інвестування в стартапи є суб’єкти внутрішнього середовища стартапів (підприємці, менеджери, персонал) та зовнішнього середовища (ангельські інвестори, венчурні інвестори (венчурні фонди), корпоративні інвестори, інкубатори та акселератори, краудфандинг-платформи, фонди прямих інвестицій, державні та міжнародні інвестиційні органи), які взаємодіють між собою в процесі витрачання/залучення всіх видів ресурсів, які були вкладені у бізнес, заснований на інноваціях, з метою розширеного відтворення його інтелектуального капіталу. Систематизовано існуючі підходи до визначення складу принципів та функцій управління інвестуванням в стартапи. Сформовано алгоритм прийняття рішень щодо інвестування в стартапи, який будується на основі певної послідовності прийняття рішень за одинадцятьма ключовими питаннями та здійсненні десяти видів ключових дій. Вихідними даними для початку використання алгоритму є наявність групи людей, які мають сформовану інноваційну бізнес-ідею. Всі суб’єкти-стейкхолдери процесу інвестування в ході взаємодії або приймають якісь рішення або здійснюють дії. Ключовими є саме рішення, послідовність яких і повинна сформувати певний алгоритм. Рішення, які приймаються в ході взаємодії стейкхолдерами мають завжди вхід і два можливі виходи (наслідки) – позитивний та негативний. Алгоритм має циклічний характер. Але на чотирьох етапах прийняття рішень стейкхолдери можуть вийти із процесу прийняття рішень щодо інвестування в стартап. На трьох етапах алгоритму інвестування можливим наслідком позитивного рішення виступає безпосередньо інвестування (ангельське, первинне, вторинне).
