Contratos de compra e venda de imóveis: uma análise das cláusulas abusivas
Authors: Latauczeski Reginaldo , Marques Simone dos Reis Bieleski
Published: December 2024

O direito contratual pauta-se no objetivo de equilibrar os dois polos da relação, ou seja, não se reputa adequado que uma das partes tenha maior vantagem em relação à outra. Uma das formas de colocar uma das partes em excessiva desvantagem em relação ao lado oposto é por meio das “cláusulas abusivas”, presentes em alguns contratos consumeristas e que devem ser consideradas nulas, sem que isso importe, no primeiro momento, em distrato. As cláusulas abusivas, nos contratos de compra e venda, afetam os direitos do consumidor e podem, em virtude disso, ocasionar danos morais, sob a forma de responsabilidade civil. A ideia é que os contratos sejam feitos e revisados por profissionais da área jurídica, pois eles são tecnicamente preparados para evitarem as cláusulas abusivas e retirá-las. Além disso, existem cláusulas abusivas que, aparentemente, são lícitas, então cabe ao advogado contratualista precaver o seu cliente e fazer com que prevaleçam os princípios da ética e boa-fé contratuais. A metodologia deste trabalho é a revisão bibliográfica, quanto ao delineamento da pesquisa, e, quanto à análise dos dados, é qualitativa. Isso posto, utilizam-se artigos científicos, doutrinas, diplomas legislativos e julgados para compor a base material da pesquisa. Nas considerações finais são revisitados os principais conteúdos de cada capítulo e, ao final, conclui-se que a revisão contratual é um mecanismo que combate à onerosidade excessiva para uma das partes e desprestigia alguma cláusula abusiva. Assim sendo, o equilíbrio contratual é restaurado assim como o respeito à dignidade humana e aos direitos fundamentais da parte lesada.

Authors: Bafana Sithokozile , Mutsvangwa Simba , Chari Felix
Published: December 2024

There has been a global plummeting trend of failure in most manufacturing Small and Medium Enterprises (SMEs) due to purported supply chain inefficiency. It is imperative for clothing manufacturing SMEs in developing nations like Zimbabwe, with reference to Bulawayo Province, which lacks digitization to integrate Information and Communication Technology (ICT) solutions into their supply chain operations to improving efficiency and maintain competitiveness in the global market. Thus, the purpose of the study was to evaluate ICT and supply chain efficiency in the clothing manufacturing SMEs in Bulawayo Province. Employing the pragmatic approach, data were collected using semi-structured questionnaires from a sample of 107 from a total population of 147 that were triangulated with 15 interviews from clothing manufacturing SMEs in Bulawayo. A simple linear regression analysis through Ordinary Least Squares was conducted to test the relationship between ICT and supply chain efficiency. The results show that ICT has a positive and statistically significant effect on cost performance, agility and delivery performance in Bulawayo clothing manufacturing SMEs. By prioritizing ICT adoption, managers can achieve better cost management, increased responsiveness to market demands, and enhanced delivery capabilities. It is recommended that clothing manufacturing SMEs in Bulawayo should embrace the ICT. Further studies should examine the relationship between ICT and supply chain efficiency in manufacturing SMEs across different industries and nations.

Published: December 2024

The fuel storage tanks in Plumpang, North Jakarta, owned by PT. Pertamina Tbk. initially had a land area of ​​153 hectares, with the use of 71 hectares as an operational area and the rest as a buffer zone. However, the buffer zone changed its function to a residential area as a place of residence and economic activities for the community which became increasingly dense accompanied by issues of land ownership status. The Plumpang fuel storage tanks fire incident that occurred several times which caused loss of life and property, is a reminder of the importance of a buffer zone that serves as a separating space between areas at risk of flammable material disasters and residential areas. This paper is the result of research on the analysis of the optimization of land requirements for the Plumpang fuel storage tanks buffer zone, by applying quantitative descriptive methods and spatial mapping of the area using Arcgis software, with reference to fuel depot safety standards. It requires the acquisition of 5.2 hectares of land as a buffer zone area in the form of a safe distance from the safety fence wall, construction of a ditch that functions as an accident pool, and re-arrangement of settlements directly adjacent to the buffer zone.

Abstract
Customer segmentation is one method that can be applied to maximize business opportunities. It can help businesses remain competitive in the market competition. The application of Artificial Intelligence (AI) can assist in providing business stakeholders with an understanding of customer segmentation based on transaction history. This study applies the Recency, Frequency, and Monetary (RFM) method combined with the K-Means++ clustering algorithm for customer segmentation. The Silhouette score serves as an indicator for selecting the most optimal value of k to determine the number of clusters. The CRISP-DM framework used in this paper also helps maintain a consistent analysis process. A simple statistical approach is used to classify each RFM feature into low, medium, and high labels to capture customer segmentation patterns. Experimental results show that k = 3 is the most optimal value based on a WSS value of 843.214747 and a silhouette score of 0.638181. The experiments also indicate that Cluster 0 has average RFM values of 1.14 (low), 1.20 (low), and 301,640 (low). Cluster 1 has average RFM values of 249.61 (high), 2.62 (medium), and 799,934 (medium). Cluster 2 has average RFM values of 233.01 (medium), 6.41 (high), and 2018.088 (high).
Artificial intelligence as an electronic person
Authors: Kuznetsov Mihail Sergeevich
Published: December 2024

With the development of technology, artificial intelligence is becoming an important part of the creative process, which raises many questions about traditional ideas about the author and copyright owner within the framework of current legislation. The article examines aspects related to artificial intelligence as a potentially new subject of copyright, analyzes its individual legal aspects in which artificial intelligence can be considered as an independent subject, and provides examples of existing precedents. At the same time, the current legislative gaps in the use of artificial intelligence as an author are being investigated, and issues related to the possibility of recognizing copyrights to works created by artificial intelligence, including the use of the term "creativity" in relation to the results of its activities, are being considered. The methodological basis is the universal dialectical method of cognition. General scientific and specific scientific methods were used : formal-logical, structural-functional, formal-legal and others. As a result of the conducted research, it was concluded that it is possible to introduce into legislation, along with a legal entity and an individual, a new entity – an electronic person. The scientific work formulates the author's concept of "electronic person", which has gained special relevance in the conditions of digitalization of modern society. It is assumed that an electronic person will be able to act as a subject of legal relations in the field of copyright, able to create new original works, recognize ownership of the results of his creative activity. In addition, the legal consolidation of an electronic person will establish the possible actual limits of the legal liability of artificial intelligence in the Russian Federation and determine who invested in it erroneous or deliberately incorrect source data that could harm both the individual and society as a whole.

In this digital era, social media has become a very effective tool for candidates and political parties to communicate, influence voters, and promote their messages. The tight world of politics requires political parties to create personal branding that differentiates them from other political parties. This research aims to explore in-depth the strategies for building personal branding carried out by new Indonesian political parties on social media. The researcher focused on three new political parties active on social media, namely the Indonesian Solidarity Party (PSI), the Indonesian Unity Party (Perindo), and the Indonesian People's Wave Party (Gelora). This research analyses the official Twitter accounts of the three parties from September 2020 to June 2023. The choice of this period is essential to maintaining data consistency and ensuring that the analysis can find strategies for building personal branding without interference from intense campaign activities. This research uses qualitative methods with a Qualitative Content Analysis (QCA) approach. NVivo12 plus software was used to help visualise the data. This research shows that PSI is building its personal branding using a millennial-style approach, Perindo is focusing on welfare issues, and Gelora Party is relying on experienced senior figures. Overall, this research emphasises that an effective personal branding strategy requires a deep understanding of the target audience, selecting relevant issues, and using credible figures.

Published: December 2024

The Cembengan ceremony is a Slametan tradition commonly practised by sugar factories before the milling season. This ritual is a prayer for high productivity and excellent safety performance in the workplace during the milling process. Wayang is then played as the highlight of the event with Semar Mbangun Kahyangan as one of the usually performed stories. This study seeks to answer this question: What are the traditional safety concepts staged in the Slametan tradition in the workplace? This study used a content analysis approach to identify, analyse, and categorise the recording data of a wayang performance with the story of Semar Mbangun Kahyangan performed by Ki Dalang Hadi Soegito. This study has found that besides human destiny had been written by God, the meaning of Safety can be pursued through a multidimensional harmony, known as manunggaling kawula-Gusti (vertical harmony), silaturahmi (horisontal harmony), the harmony among five knights of Pandawa as a symbol of the physical harmony of five senses (sight, hearing, taste, smell, and touch) and psychological-spiritual harmony. The second finding is that a safety attitude is fostered in line with human development, which is symbolised in Wayang's storyline, first, on the Pathet Enem (infancy to adolescent) safety attitude generated by right-wrong consideration. Second, a safety attitude is an ethical decision within Pathet Sanga (early to middle adulthood). Last, at Pathet Mayura (late adulthood), a safety attitude is a spiritual achievement.

Published: December 2024

This study examines how post-structuralist visual identities and counter-hegemonic practices are expressed through digital street art on the Instagram account specifically onn @visual.jalanan account. Using a qualitative content analysis, this research focuses on posts made between January to May 2024, coding visual and textual elements to identify themes of hybridity, fragmentation, and resistance. This study selected 127 posts based on relevance to socio-political discourse and public engagement metrics such as likes and comments. The findings reveal that Instagram serves as a platform for cultural expression and social critique, enabling artists to bypass traditional gatekeepers. The artworks analysed in this study challenge dominant narratives related to nepotism, political propaganda, corruption, and cultural homogeneity. These artworks foster fluid identities and critical dialogue through visual satire and audience interaction, exemplifying post-structuralist principles. This research highlights Instagram’s role as a counter-hegemonic medium that contests mainstream narratives by amplifying marginalised voices. The study contributes to the scholarship on digital media art and visual identity by demonstrating how digital platforms enable innovative artistic expression and resistance to socio-political structures. Future research should explore the evolving role of digital platforms in sustaining counter-hegemonic movements and engaging with political advocacy in Indonesia.
Islamic personal branding strategies in the 2024 local election in Central Aceh
Authors: Mustafa Ali
Published: December 2024

This study investigates the application of Islamic personal branding tactics by politicians competing in the 2024 Central Aceh local elections. This research, rooted in the theoretical framework of personal branding and political communication, examines how politicians in this primarily Muslim region leverage diverse media channels to shape their public image and engage the local population. The study employs a qualitative technique, including text analysis, observations, and document inspection, to evaluate the personal branding tactics of a sample of ten politicians across various media platforms that include the internet, social media, and print media. The data collection period spans six months before the 2024 Central Aceh local election. The findings show that politicians make substantial use of Islamic rhetoric, symbolism, and the involvement of religious authority to boost their personal brands. They use a consistent media strategy, carefully incorporating these Islamic personal branding elements across several interconnected mediums. Nonetheless, the study emphasises the difficulties of guaranteeing consistency between the leaders' crafted image and their actual behaviour and policies. This study enhances the limited academic understanding of the influence of religion on personal branding and political communication, specifically regarding local elections in predominantly Muslim areas. The insights acquired can guide the formulation of more effective and ethical personal branding strategies for politicians aiming to engage with their people.

Authors: CONTESA YENIS , Surwandono
Published: December 2024

In a dynamic political context, presidential speeches are crucial in shaping public perception and guiding policy. President Joko Widodo's latest speech on August 16, 2024 that was uploaded through the Presidential Secretariat's YouTube channel, has come under scrutiny for containing important elements relating to communication strategies and leadership legitimacy. This study aims to analyse the speech by exploring how Jokowi's distinctive rhetoric reflects his role in the political agenda. Using a qualitative approach and Van Dijk's critical discourse analysis technique, this study employs a socio-cognitive framework to guide the analysis. Lingual data was collected through free listening techniques, including transcription, observation, and research subject determination. Meanwhile, non-lingual data was obtained from credible news documents and analysed using hermeneutics and phenomenology methods. The results showed that Jokowi built his image as a responsive and effective leader through language that highlighted the successes and challenges of his leadership and built leadership authority by presenting himself as a skilful, strategic, and reality-based leader. This research contributes to understanding rhetorical strategies in political communication and leadership authority studies, with far-reaching implications for public perception and political dynamics.

Шлемник байкальский (Scutellariae baicalensis) – одно из наиболее популярных растений традиционной китайской медицины. Благодаря входящим в его состав активным компонентам, таким как байкалин, байкалеин, вогонин и скутелларин, оно используется при лечении воспалительных процессов, гипертонии, сердечно-сосудистых заболеваний, а также при бактериальных и вирусных инфекциях. В данной работе представлен чувствительный и селективный способ одновременного определения этих соединений в экстрактах из растительного сырья с использованием метода высокоэффективной жидкостной хроматографии и тандемной масс-спектрометрии с электрораспылительной ионизацией в режиме регистрации выбранных ионных переходов. Проведена апробация предложенного подхода при анализе коммерчески доступных образцов корня Scutellariae baicalensis. Для проведения хроматографического разделения определяемых соединений использовался обращено-фазовый сорбент Acclaim RSLC С18. При определении каждого из соединений были достигнуты следующие пределы обнаружения в режиме регистрации выбранных ионных переходов: для вогонина и байкалина – 1 нг мл–1, скутелларина – 3 нг мл–1, байкалеина – 4 нг мл–1. Диапазон линейности градуировочной зависимости стандартных растворов составил 20-2000 нг мл-1 для скутелларина и 20-500 нг мл-1 для вогонина, байкалина и байкалеина.

Scutellariae baicalensis is one of the most popular herb in the traditional Chinese medicine. It is used for the treatment of inflammatory process, hypertension, cardiovascular diseases, and also in treatment of bacterial and virus infections due to such active components as wogonin, scutellarin, baicalin and baicalein that are contained in this herb. A sensitive and selective technique of simultaneous determination of these compounds in the extracts from plants raw materials using high performance liquid chromatography tandem mass spectrometry with electrospray ionization was developed. The proposed method has been successfully tested on the commercially available samples of Scutellariae baicalensis root. Analysis of samples was carried out using a reversed-phase chromatography with Acclaim RSLC C18 sorbent. Using multiple reactions monitoring the following limits of detection were achieved: 1 ng mL-1 for wogonin and baicalin, 3 ng mL-1 for scutellarin and 4 ng mL-1 for baicalein. It was found that calibration curve was linear in the concentration range of 20 ng mL-1 and 2000 ng mL-1 for scutellarin and 20 ng mL-1 and 500 ng mL-1 for wogonin, baicalin and baicalein.

Зарегистрированные при низкой энергии электронов масс-спектры отрицательных ионов глюкозы и фруктозы свидетельствуют о глубокой фрагментации короткоживущих молекулярных ионов. Анализ метастабильных ионов в масс-спектрах показывает, что некоторые реакции распада протекают через промежуточные ионы: [M–H2O]–· и др. Наряду с общим сходством процессов ионообразования в изомерах наблюдается существенное различие, заключающееся в интенсивном образовании ионов с m/z 71 из глюкозы.

Low-energy negative ion mass spectra of glucose and fructose suggest deep fragmentation of short-lived molecular ions. Analysis of metastable ions in the mass spectra shows that some decomposition reactions proceed through intermediate ions [M-H2O]– •, etc. Along with the general similarity of ionization processes in the isomers, there is a significant difference in the intensive formation of ions at m/z 71 from glucose.

Изучена возможность использования ряда ароматических и гетероароматических карбоновых кислот и их галогенангидридов в качестве реакционноспособных матричных соединений для анализа спиртов различного строения методом масс-спектрометрии с матрично-активированной лазерной десорбцией/ионизацией (МАЛДИ). Показано, что взаимодействие спиртов с хлорангидридами никотиновой и хинолин-6-карбоновой кислот позволяет получать производные, обладающие высокой эффективностью десорбции/ионизации в условиях МАЛДИ, а образующиеся в результате гидролиза ангидридов свободные кислоты выступают в качестве матричных соединений. Предложенный подход опробован на ряде алифатических, алициклических и ароматических спиртов.

The possibility of using a number of aromatic and heteroaromatic carboxylic acids and their halogen anhydrides as reactive matrix compounds for the analysis of alcohols of different structures by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry has been studied. It is shown that acylation of alcohols with nicotinic and quinoline-6-carboxylic acid chlorides makes it possible to obtain derivatives having a high desorption/ionization efficiency under MALDI conditions, and the free acids formed as a result of the hydrolysis of anhydrides act as matrix compounds. The proposed approach is tested on a number of aliphatic, alicyclic and aromatic alcohols

Предложена методика оценки содержания отдельных групп соединений – свидетелей аноксии в фотическом слое бассейна седиментации, а также их общего содержания во фракциях нефтей и рассеянного органического вещества. Проанализированы целесообразные варианты представления полученных данных. На основании информации об общем содержании свидетелей аноксии предложен способ ответа на вопрос: являлось ли сероводородное заражение постоянным, охватывающим большую толщу воды, или эпизодическим, распространявшимся на ограниченный водный слой. Эти данные позволяют также оценить роль органического вещества, сформировавшегося в условиях аноксии, в его общем балансе. Предложен параметр состава, позволяющий выяснять, насколько близки были условия трансформации органического вещества в разных породах.  

A technique is proposed for estimating the content of individual groups of compounds - anoxia markers - in the photic layer of the sedimentation basin and their total content in fractions of oils and dispersed organic matter. Appropriate variants of presenting the data are analyzed. Based on the data on the common content of anoxia markers, a method has been proposed for answering the question of whether hydrogen sulfide contamination was permanent, covering the major part of the water column, or there was an episodic infection that spread to a limited water layer. These data also allow one to estimate the role of the organic matter formed under anoxic conditions, in its general balance. Composition parameter is proposed that allows one to determine the similarities in the conditions of organic matter transformation in different rocks.

Описана методика определения изотопного состава высокообогащенного кремния в виде элементарного 28Si и исходного 28SiF4 методом масс-спектрометрии высокого разрешения с индуктивно связанной плазмой в широком диапазоне изотопных концентраций (более 6-ти порядков величины). Для расширения диапазона измеряемых изотопных концентраций сигналы основного и «примесных» изотопов регистрировали в растворах разной концентрации. Определение коэффициентов матричного влияния и дискриминации по массам проводили с применением метода изотопного разбавления. Данная методика позволила реализовать неопределенность измерения концентрации основного изотопа до десятитысячных долей процента при обогащении > 99.999% на одноколлекторном масс-спектрометре высокого разрешения с индуктивно связанной плазмой. 

A technique for determining the isotopic composition of highly enriched silicon in the form of elementary 28Si and initial 28SiF4 by a single collector double focusing sector field ICP-MS over a wide range of isotope concentrations (more than 6 orders of magnitude) was described. To expand the range of measured isotopic concentrations the signals of the main and "impurity" isotopes were recorded in solutions of different concentrations. Determination of the matrix effects and the mass discrimination factors was carried out using the isotopic dilution method. This technique allowed us to realize the uncertainty of measuring the concentration of the main isotope to ten thousandths of a percent when enriching > 99.999% on a high-resolution single-collector mass spectrometer with inductively coupled plasma.

Для извлечения элеутерозидов из растительных материалов были применены простые и экспрессные способы, включающие экстрагирование в ультразвуковой ванне различными растворителями. Линейная область градуировочного графика находилась в диапазоне от 40 до 4000 нг мл-1.

Eleutherococcus senticosus is a plant with medicinal properties due to the presence in the roots and rhizomes of glycosides, called eleutherosides А, В and В1, C, D, E, F. In this paper, the technique of simultaneous determination of Eleutheroside B and Eleutheroside E in dry samples of Eleutherococcus senticosus roots of different manufactures by high performance liquid chromatography/tandem mass spectrometry was proposed. Quantitation of eleutheroside B and eleutheroside E was performed using electrospray ionization in negative ion mode with detection by multiple reaction monitoring (MRM), which ensured a better signal to noise ratio. To isolate eleutherosides from plant materials, simple and rapid methods of sample preparation were used, including extraction in an ultrasonic bath with various solvents. The calibration curve was linear in the concentration range of 40 ng mL-1 and 4000 ng mL-1.
