Published: September 2023

One of the ways to reduce protein deficiency and produce complete feed is the cultivation of alfalfa-grass mixtures, which, due to the optimal ratio of protein and carbohydrate compounds, mineral salts and other valuable biologically active substances, most fully meet the physiological needs of animals. The purpose of the research was to determine the effect of mineral fertilisers on the nutritional value of alfalfa-cereal grass mixtures. Experimental studies were conducted during 2014-2016 on the experimental field of the Department of Feed Production, Land Reclamation and Meteorology, which is located in the SE NUBiP of Ukraine “Agronomic Research Station” on typical low humus black soil. The results of the conducted research revealed that the inclusion of alfalfa in cereal grass stands increases the content of crude protein to a greater extent than the application of nitrogen at the rate of N60 on the same cereal grass stand on the same background of P60K90. There were no significant differences in crude protein accumulation between alfalfa-grass stands with different cereal components on the same backgrounds. The introduction of alfalfa into grass stands promotes the growth of protein and crude fat in the feed and reduces the content of nitrogen-free extractives. The chemical composition of grass feed is most affected by nitrogen fertilisers on grass stands. With the introduction of N60 on the background of Р60К90 the dry weight of the feed increases by 2.8% of the crude protein content and 26 g of the provision of a feed unit with digestible protein. The digestibility of the dry mass of alfalfa and legume-cereal grass stands relative to pure cereals increases by 2-5%. The composition of cereal components in legume-cereal mixtures and the fertiliser system do not significantly affect the digestibility of feed. On all studied grass stands the highest quality of forage is provided by the introduction of N60P60K90+ Fumar

Authors: Shabiriani Uzda Nabila
Published: September 2023

There are meanings, stories and philosophies of the life of the ancestors of the Asei people which have been depicted on the bark for generations since 1600 and produce images related to the living space of the Asei people. The purpose of this study was to determine the meaning of the symbolic forms that exist in the Asei bark painting motifs related to the life of the Asei people and their social system. This study analyzes the colors that are often used and the dominance of images in Asei bark painting motifs. From the results of the analysis, 4 Asei bark paintings often use red from betel nut, black from charcoal and white from chalk. Then the images that are often displayed in bark paintings are images of fish, coral (hak balu), fouw, and spears and hooks. The meaning of the symbolic forms shown in the dominance of colors and images on the Asei bark painting is that the Asei people want to tell the geographical conditions of the Asei island which is surrounded by water, Asei Island as a protector for the people, the daily livelihood of the Asei people, the existence of family relationships and the strong togetherness of the Asei people, as well as the community's respect for the ancestors who have protected Asei Island as well as possible.

Published: September 2023

This research is motivated by the trend of snacks with a salty or sweet taste which have become part of people's lifestyles, especially among teenagers and young adults. Snacks portion that exceeds the serving size has an unfavorable impact on the body's calorie intake. This study aims to analyze the effect of the size of the snack packaging portion in the form of one serving (individual pack) and family portion (family pack), on the eating patterns of teens and young adults. The population in this study were active students from several universities in Bandung, Indonesia. Data collection was done by distributing questionnaires to respondents. The study was conducted using descriptive statistical calculations and inferential statistics, namely the comparison between respondents' preferences for the choice of snack packaging that is packaged according to the serving sizes and packaged in larger sizes. Teenagers and young adults choose snacks with larger packages, both from the salty and sweet snack groups. Larger packaging sizes dominate purchasing decisions. They consume more snacks if served in larger packages. Consumers prefer large packaging which is more economical because small packaging does not have a visible added value. Individual packaging is only effective when carried or when you want to eat less snack. Based on the conclusions, further research that focuses on increasing the value of single-serving packages, how to pack family-sized snacks (family packs) to increase awareness of snack portions, or how other efforts can be made to change the behavior of eating excess snack portions can be further explored.

The world is experiencing rapid growth of nickel (Ni) demand, especially for lithium-ion batteries used in electric vehicles, while high-grade Ni deposits are being depleted due to expanding economics, growing populations, and disorganized industrialization. Therefore, a major transformation from high-grade low-bulk ores to low-grade high-bulk ores is necessary to secure the future supply chain of Ni [1]. In this context, ultramafic soil is considered a low-grade high-bulk Ni ore, mostly found in tropical countries. However, conventional mining practices are high energy-consuming and generate a tremendous amount of waste, making it impracticable to recover Ni from ultramafic soil. Therefore, phytomining (or farming for metals) is identified as a viable and innovative method for Ni recovery from low-grade high-bulk sources such as ultramafic soil.
Unlocking the Power of Big Data: How Remote Sensing and Land Zoning Data are Revolutionizing Urban Planning

Published: September 2023

Urbanization is a rapidly growing trend, and cities are facing unprecedented challenges in managing growth, ensuring sustainability, and promoting social equity. Urban planning is a complex and challenging process, as it involves the coordination of various stakeholders and the management of different resources. So, utilizing conventional methods for urban planning can lead to limited data availability, inaccurate data, and a lack of stakeholder engagement, which can affect the quality and effectiveness of the planning process for highly populated areas. There¬ fore, with the advent of big data and remote sensing technology, urban planners now have powerful tools to tackle these challenges. Remote sensing is the use of satellites, aerial imagery, and other sensor-based technologies to gather data about the earth’s surface. Land zoning data, on the other hand, provides information about the designated use of land in each area. When combined, these two types of data can provide a comprehensive view of land use, environmental conditions, and social dynamics. One of the main benefits of remote sensing and land zoning data is their ability to provide real-time monitoring of urbanization patterns. By tracking changes in land use and environmental conditions, urban planners can make informed decisions about infrastructure development, environmental protection, and social equity. This information can also be used to anticipate future trends and respond proactively to emerging challenges.

Politik Hukum Pembuktian dalam Penyelesaian Sengketa Konsumen di Indonesia
Authors: Syam Misnar
Published: September 2023

Guidelines (GBHN) of Indonesia, including through the Decree of the People's Consultative Assembly (TAP MPR) No. II of 1988. Consumer protection is regulated by Law No. 8 of 1999 concerning Consumer Protection. Repressive protection is an effort to restore the losses suffered by consumers. In any consumer dispute resolution process, evidence is required. Under the Consumer Protection Law (UUPK), the burden of proof is shifted, as stipulated in Articles 19, 22, 23, and 28, where the burden of proof falls on the business entity obligated to prove its innocence. Evidence in civil procedure law is regulated in Article 163 of the HIR/283 RBg, following the ordinary burden of proof. This leads to a lack of harmony in the regulations, which can result in confusion and legal uncertainty in its implementation. This can hinder the achievement of the goals of consumer protection. Legal policy is the direction of future legal regulations, so when making laws, it is necessary to refer to Indonesia's legal policy. Based on the above reasons, the research problem in this study is how evidence is handled in the resolution of consumer disputes from the perspective of Indonesian legal policy. The research method used is normative. In conclusion, in the legal policy of consumer protection, especially in the dispute resolution process, there is a need for harmonization between the Consumer Protection Law (UUPK) and future civil procedural law to ensure legal certainty.

Background: Non-alcoholic fatty liver disease (NAFLD) individuals are more prone to acquire type 2 diabetes (T2DM). However, the knowledge regarding this phenomenon is limited to individuals without diabetes mellitus (DM). Vitamin D deficiency may lead to a more pronounced shift in an individual's glucose metabolism. Moreover, hepatocytes and peripheral tissues may potentially benefit from vitamin D in terms of reducing insulin resistance induced by free fatty acids.  Objective: In this study, serum vitamin D levels were examined in patients with NAFLD with T2DM, and its relationship with NAFLD without DM was evaluated.Subjects and Methods: A total of 120 subjects were included in this study, divided into three groups: Group I included 30 healthy subjects matched for sex and age, Group II included 50 patients with NAFLD who had diabetes, and Group III included 40 subjects without diabetes. Three groups were compared regarding clinical and biochemical characteristics concerning serum 25-hydroxyvitamin D levels using enzyme-linked immunosorbent assays.Results: According to this study, people with NAFLD diagnosed by ultrasound examination Group II had significantly reduced serum levels of 25(OH) vitamin D compared to patients without NAFLD diagnosed by ultrasound examination Group II. There was a statistically significant difference between groups and 25(OH) vitamin D levels than group III. In addition, a highly significant difference in serum 25(OH) vitamin D levels was observed between groups II and III and the control group. Moreover, 25(OH) vitamin D is an independent predictor of T2DM in patients with NAFLD.Conclusion: Serum 25(OH) vitamin D levels were lower in patients with NAFLD and DM, indicating that low 25(OH) vitamin D status contributes to the onset and progression of diabetes mellitus in NAFLD.Keywords:25-hydroxy vitamin D[25(OH)D)], Non-alcoholic fatty liver disease (NAFLD), diabetes mellitus.

The lack of ability to control human activities led to changes of land use/land cover (LULC) in Dalat City where rapid urbanization and the demand to expand agricultural land have resulted in dramatic forest reductions. This study assessed the rate and extent of LULC changes over the past 12 years and simulated future scenarios in Dalat City, Lam Dong Province, Vietnam by using an integrated model of Markov chain and logistics regression. Three land-use maps used to analyze land-use change were extracted from satellite images in 2010, 2016, and 2022 by classification approach. The outcome of this process indicates a significant increase in agricultural and built-up land of 48.22 km2 and 9.36 km2, respectively; a decrease in forest land of 55.61 km2, and a minor change in water bodies and bare land in the 2010-2022 period. Prediction maps of land-use change in 2028 and 2034 are generated after the model is validated by comparing the actual map with the prediction map of LULC in 2022 using Kappa statistics. Transition of forest area to other land use types, especially land for expansion of built-up and agricultural land is the crucial trend of land-use change in the future according to the forecast model. Compared to 2022, forest area in 2034 will decrease by 60.65 km2 while built-up and agricultural land will increase by 14.07 km2 and 43.61 km2, respectively. The research results provide valuable information as a foundation for land-use policy planning and local urban development to ensure sustainable development objectives.

A Portrait of an EFL Learners' Explanation Text: Cohesion and Coherence
Authors: Williyan Aldha
Published: September 2023

This study aims to explore cohesion and coherence in an explanation text written by an EFL learner.  To do this, the cohesive devices of the explanation text are analyzed.  Also, the text is analyzed using the Thematic progressions theory to find out the logical relationship of the sentences and whether or not the text can meet the readers’ expectations.  There are several steps to analyze both elements.  The first is broking up the paragraphs of the text into sentences.  The second is using Thematic progressions to analyze the text.  Finally, the writer analyzed the cohesive devices which function to connect sentences.  All those data later are elaborated in paragraphs as descriptive-qualitative research design is employed in this study.  The results shows that, in term of cohesive devices, the writer uses direct repetition, partial repetition, and same lexical set to build lexical cohesion.  It is also found that the writer uses reference, substitution, and ellipsis to build grammatical cohesion.  However, the writer seems to have insufficient knowledge to use the cohesive devises correctly.  Additionally, the analysis of Thematic progressions shows that some sentences in the text have no logical relationship.  Lastly, this study finds that the writer also seem to have insufficient knowledge of schematic structures of the explanation text.

A béke érdekében folytatott vallásközi és államközi diskurzus, valamint a mediáció mint módszerek jelentősége a béketeremtésben és békefenntartásban
Authors: Piróth Emese
Published: September 2023

Napjaink egyik meghatározó kihívása a béke és a stabilitás megteremtése, amely jelentős fejtörést okoz állami és egyházi szinten egyaránt. E cikk két olyan, a békefenntartáshoz és béketeremtéshez eszközként, kiegészítőként értékelhető módszer hasznossága mellett szeretne érvelni, amelyekhez szükséges a felek részéről egy bizonyos szintű nyitottság a kooperáció irányába: jelen cikk írója szerint az állam és az egyház kooperációja gyümölcsöző lehetne a konfliktusok és válsághelyzetek megelőzési szakaszábanpárbeszéd formájában, valamint a konfliktus eszkalálódása után egy alternatív vitarendezési módszer, a mediáció alkalmazásával. A béke percepciójával kapcsolatos nézetek, valamint az e területhez köthető állami és egyházi feladatok ismertetése után a cikk fő része ezeknek a módszereknek a sajátosságaival foglalkozik, valamint azt igyekszik megvilágítani, hogy miért is lehetnek ezek hasznos módszerek egy olyan konfliktusokkal terhelt térségben, mint a MENA-övezet.

Mechanism of Action and Use of Radiomimetic Compounds (Part 2)
Authors: Deli Gábor
Published: September 2023

Radiomimetic compounds, similarly to ionising radiation can directly or indirectly cause DNA damage. Two major groups of these compounds, alkylating agents and antimetabolites, have already been discussed in the first part of this article. The topic of this article is an overview of radiomimetic substances of biological origin; they are grouped and discussed upon their chemical structure. Some bacteria, belonging to the class of Actinobacteria can produce compounds with radiomimetic property as part of their defence mechanisms, such as bleomycins, enediynes, streptonigrins, etc. Radiomimetic compounds of bacterial origin can be divided into three main groups: radiomimetic glycopeptides, enediynes and quinone antibiotics. Each of them induces double-strand DNA breaks. Some of them work through their reactive radicals and the molecules are also transformed when they break DNA. Others, such as bleomycin and similar glycopeptides, have an enzyme-like catalytic effect as the molecule regenerates itself after interacting with DNA thus the same molecule can create new DNA breaks again. The damage caused by radiation and by bleomycin is very similar: double DNA strand breaks occur in close proximity to each other, below the lethal dose of the cell, so as the cell does not die, the DNA repair process is activated, which can lead to the formation of dicentric chromosomes and other detectable DNA alterations. This review briefly summarises the mechanism of action of bacterial radiomimetic compounds and their benefit.

Background and Aims The quick speech in noise (Q-SIN) test shows how difficult it is to perceive speech in noise by determining signal-to-noise ratio (SNR) loss. The lists with high-frequency words have a better ability to identify SNR loss which have been created in Persian. Although a Persian version of Q-SIN with emphasis on high frequency is available، but there is no Q-SIN lists with high-frequency words; therefore,this study aims to develop new lists and the lists with high-frequency words for Q-SIN test and determine their equivalency in normal-hearing people which was condcuted in Tehran University of Medical Sciences. Methods The sentences were first developed. Then, their content validity and face validity were determined. In this regard، 36 sentences were used to make new Q-SIN lists and 36 sentences were used to make Q-SIN lists with high-frequency words. Based on the Q-SIN test development criteria، six regular lists (lists 1-6) and six lists with high-frequency words (lists 7-12) were tested on 46 people (23 males and 23 females) aged 18-35 with normal hearing Results The content validity index for new and high-frequency words lists were 0. 74 and 0. 736، respectively. The equivalency test results showed that among the first 6 lists، the lists no. 1, 2, 3, and 4 were equal. Among the six lists with high-frequency words, the lists no. 7, 8, 10, 11 were equal. There was no gender differences between six regular lists and high-frequency lists (P>0.05). Conclusion The Q-SIN word lists with equivalency can be used for normal-hearing people in clinical practice.

Background and Aims Balance is an important factor in people with intellectual disability to have an independent life. These people are weak static and dynamic balance due to lack of development in their central nervous system, defects in the sensory-motor pathways, and having a sedentary life. This study aims to determine the effect of eight weeks of dynamic neuromuscular stabilization (DNS) exercises on static and dynamic balance of educable mentally retarded female students Methods In this study, participants were 26 educable mentally retarded female students aged 15-20 years (Mean age: 17.19±1.50 years, IQ: 61.15±6.07, weight: 58.9±12.73 kg, height: 157.92±6.07 cm) who were selected using purposive and convenience sampling methods and randomly divided into two groups of training (n=13) and control (n=13). Before and after training, their static balance and dynamic balance on the right and left feet were evaluated using a foot scan device. Subjects in the training group performed DNS exercises at 24 sessions, each session for 40 minutes. No intervention was provided to the control group; they performed their routine activities. Repeated measures analysis of variance was used to analyze the data. The significance level was set at 0.05. Results After eight weeks of DNS exercises, the results showed a significant improvement in static balance (F=72.54, P=0.001), dynamic balance on the right foot (F=90.90, P=0.002) and dynamic balance on the left foot (F=61.58, P=0.001) in the training group compared to the pretest scores and compared to the control group. Conclusion DNS exercises can be used as an effective method to improve static and dynamic balance of educable mentally retarded female students.
