Acreage Response to Price Support and Price Risk under Trade Liberalization
Authors:   The Korean Agricultural Economics Association, Kim Cherry , Kim Kwansoo
Published: November 2022

An unexpected surge in sugar imports in 2008 under NAFTA resulted in a large U.S. sugar price fluctuation. This study explores the acreage decision for U.S. sugar beets in an environment where both price support and trade liberalization takes place at the same time. Our empirical analysis is based on county-level data for sugar beets and three substitute crops (corn, soybean and wheat) in twelve U.S. sugar beet growing states over 1997-2018. While we find that an increase in price fluctuation overall has adverse impacts on acreage, the results indicate that farmers respond to price risk differently before and after NAFTA and to the level of price risk. This suggests a need for more precise policy instruments that better protect against unexpected income loss rather than a fixed level of support and enable producers to deal with future extreme events.

Published: November 2022

We investigated the growth and convergence in Vietnamese rural income using the household survey data, VHLSS of the years, 2004 and 2018. The regional convergences in the district level income sources were estimated and tested. We found that real agricultural income, off-farm income, and the whole farm income all increased and converged, but the convergence rate in off-farm income was much higher than that in agricultural income. The convergence in income implies that an overall increase in rural income in Vietnam will contribute to reducing poverty rate. We also found that the geographic characteristics are the main determinants of agricultural income growth rates. On the other hand, ethnic minorities and people living in poverty have difficulties in developing off-farm income sources despite the convergence tendency of off-farm income.
An Appraisal of the Colombia DDR Process in Light of the Revised Peace Agreement between the Government and the FARC
Authors: Capone Francesca
Published: November 2022

After more than four years of negotiations the Colombian Government and the FARC have reached a historical peace agreement, signed on 26 September 2016 and, in a shocking turn of events, ultimately rejected in an up-or-down referendum held on 2 October 2016. Only 41 days after the plebiscite the two parties have revised the original deal and submitted a new version to the Congress, which approved it on 30 November 2016. The deal, upon which relies the possibility to finally achieve a stable and lasting peace, covers several crucial issues, including what will happen to the FARC rebels once the armed conflict is officially over.

The establishment of an effective DDR process is an essential step to ensure that FARC members will meaningfully transition into civilian life and it represents one of the most controversial aspects of the peace agreement. Moving from the assumption that DDR programmes are not stand alone mechanisms, but fall within a broader framework that covers a number of important and intimately entwined aspects, like the issue of accountability and the rights of victims, the present article, after looking at Colombia’s past attempts to reintegrate former combatants, aims at discussing the DDR process envisaged in the current peace deal, highlighting its main strengths and shortcoming.

OPTIMIZATION-INFORMATION MODEL OF ENTERPRISE BUSINESS PROCESS MANAGEMENT
Authors:   Institute of Labour and Social Studies in Warsaw, Abramowicz Maciej
Published: November 2022

The purpose of the study is to develop an optimization-information model of enterprise business process management under conditions of risk. The success of any enterprise in conditions of risk is directly determined not only by potential, but also directly depends on the optimization and control of business processes at the enterprise. Based on the study of the theory and analysis of business practice, it was established that today there are problems that are directly related to the features, economic-mathematical modeling and optimization of business processes at enterprises in conditions of risk. It is noted that the process of optimizing business processes at the enterprise is aimed at increasing the potential of the enterprise, as well as at increasing profits. Profit as the value of the final result of business – the specific amount by which revenues exceed the costs associated with them (that is, exceed the amount of costs incurred in the process of economic activity). According to the results of the conducted research, a new optimization-information model of enterprise business process management is presented. With the help of this model, the conditions for the implementation of an effective technological process are established, taking into account the criterion of quality of sustainable development and risks. Here, the technological process should be understood as a set or system of certain operations on the use of raw materials and materials, technology and the manufacture of finished products. Taking into account the quality functional and restrictions on risks, a new optimization-information model and a new approach have also been developed to assess the optimal amount (volume) of information, the reliability coefficient and the optimal profit, while implementing an effective technological process. It is advisable to carry out further research in the direction of evaluating the effectiveness of business processes and technological development of enterprises.

Published: November 2022

A BF3-catalyzed atom-economical fluorocarbamoylation reaction of alkyne-tethered carbamoyl fluorides is reported. The catalyst acts as both a fluoride source and Lewis acid activator, enabling the formal insertion of alkynes into strong C–F bonds. Our proposed mechanism involves fluoride addition to the alkyne via a nucleophilic fluoroborate species, followed by cyclization onto the carbamoyl moiety with concomitant release of fluoride. The developed method provides access to 3-fluoromethylene oxindoles and γ-lactams with excellent stereoselectivity, including fluorinated derivatives of known protein kinase inhibitors.

Poor ventilation in classrooms can increase the risk of infectious disease transmission, such as COVID-19, because it allows respiratory aerosol particles that may contain viruses to accumulate. Air purifiers can effectively reduce transmission rates in community spaces, including classrooms, because they increase the air change rate in the room and reduce particle concentrations. In this study, we investigate the effectiveness of Corsi-Rosenthal Boxes (C-R Box) in reducing particle concentrations in active, occupied classroom settings. A C-R Box is a do-it-yourself, cost-effective alternative to commercial air purifiers built from a box fan, four readily available filters, cardboard, and duct tape. We collected measurements of coarse (particles with diameters > 2.5μm) and fine (particles with diameters 0.5μm - 2.5 μm) particle number concentrations and PM2.5 (particles with diameter < 2.5μm) mass concentrations. Specifically, we compared measurements in occupied classrooms before and after we turned the C-R Boxes on. In our testing, C-R Boxes reduced fine particle number concentrations by 56-91% and PM2.5 mass concentrations by over 70% after we turn on the C-R Boxes. We also simulated velocity profiles in the classrooms with running C-R Boxes showing mixing throughout the classroom ensuring that all air can encounter the filter.
Nanostructural Organization in a Biredox Ionic Liquid
Authors: Berthin Roxanne , Serva Alessandra , Fontaine Olivier , Salanne Mathieu
Published: November 2022

Ionic liquids generally display peculiar structural features that impact their physical properties, such as the formation of polar and apolar domains. Recently, ionic liquids functionalized with anthraquinone and TEMPO redox groups were shown to increase the energy storage performance of supercapacitors, but their structure was not characterized so far. In this work we use polarizable molecular dynamics to study the nanostructuration of such biredox ionic liquids. We show that TEMPO nitroxyl functions tend to aggregate, while the anthraquinone groups favor stacked arrangements. The latter eventually percolate through the whole liquid, which sheds some light on the mechanisms at play within biredox ionic liquids-based supercapacitors.

Authors: Rokytianskyi A. , Gamulya Yu.
Published: November 2022

The article presents results of the study of flora of the reservoirs in the eastern part of the Dnieper-Donetsk basin. An annotated list of flora was compiled on the base of personal field research, analysis of herbarium materials, and available literature data. The annotated list provides information on the herbarium specimens, species distribution in the study region, its general geographic distribution, habitat ecology, conservation status, life form, economic significance, and known literature references in the study region. It is established that the flora of water bodies of the area in question includes at least 61 species of higher aquatic vascular plants. The family Potamogetonaceae is the most species-rich (18 species, about 30% of the total aquatic flora of the region). The most species-rich genus is Potamogeton (16 species); other taxa are represented by a small number of species. A dominant life form is a group of submerged rooted aerohydatophytes, which numbers 28 species (45.9% of the total flora); the rooted aerohydatophytes with leaves floating on the water surface account for 12 species (19.6%). In terms of geographical distribution, the most abundant is the species group with a circumpolar type of area (28 species). Fourteen species have Eurasian ranges. Other area types are represented by a small number of species. The aquatic flora of the eastern part of the Dnieper-Donetsk basin has a high sozological value. Twenty-six species (42.6% of the flora) have conservation status. The Red Book of Ukraine includes six species, viz. Aldrovanda vesiculosa L., Utricularia intermedia Hayne, U. minor L., Salvinia natans (L.) All., Trapa natans L., and Nymphoides peltate (S.G. Gmel.) Kuntze. Three of them are listed in Annex I of the Berne Convention, and the other three are tertiary relics. Three species are included in the European Red List of Vascular Plants. The list of rare, endangered, typical, and in need of special protection plant groups (Green Book…., 2009) includes 14 aquatic assemblages. Recently, against the background of a general decrease in autochthonous floristic diversity, new invasive species have appeared in the region, behaving aggressively towards the native flora: Pistia stratiotes L. and Eichhornia crassipes (Mart.) Solms.
What the distribution of sperm size can tell about the stability of spermatogenesis in hybrid frogs Pelophylax esculentus
Authors: Fedorova A. , Pustovalova E.
Published: November 2022

Interspecies hybrid frogs Pelophylax esculentus and one of its parental species Pelophylax ridibundus inhabit the Siversky Donets center of diversity of water frogs in Eastern Ukraine. These frogs can crossbreed and form progeny in population systems which are called hemiclonal (HPS). Such systems have their own exceptional features which make them interesting for studying. The Lower Dobrytskiy Pond, which is situated in the National Nature Park “Homilshansky lisy” and is a part of Siversky Donets river basin, is on focus. Current work is devoted to the combination of two methods of spermatogenesis investigation. First, using the method of Ag-staining we observed high variability of meiotic chromosomal plates in testes of 24 adult male water frogs P. esculentus (2n=26). Only one male had 100% of full meiotic plates with no aneuploid plates. A significant amount of studied males (21/24) produced aneuploid chromosomal plates (4-68% of the total amount of meiotic plates). This may lead to a decrease in their fertility or even to their entire sterility. Also, we have not observed any chromosomal meiotic plates in two of 24 males. Some males (8/24) even produced meiotic chromosomal plates with 26 bivalents (i.e. 4n germ cells) which may testify about the ability to produce diploid sperm. Further, the lengths of urinary sperm cells’ heads were measured. Finally, we performed an analysis of both meiotic chromosomes in testes and the distribution of sizes of urinary sperm cells’ heads of hybrid water frogs Pelophylax esculentus from Siversky Donets basin to find out if there is a link between these two features. No difference in sperm heads lengths was found between males producing moderate and low amounts of sperm. Based on the data of meiotic plates all males were assigned into five categories via PCA (principal component analysis). A significant difference in sperm heads lengths was found within the category I (males with mostly full meiotic plates). The analysed data shows that each male from the studied population has his own unique features. No direct link between sperm cells size and features of meiotic chromosomes in testes was found.
Influence of the photoperiod duration on the biological properties of PGPR-bacteria of the soybean rhizosphere (Glycine max (L.) Merr.)
Authors: Hlushach D. , Zhmurko V.
Published: November 2022

Physiological and biochemical properties of the PGPR-bacteria isolated from the rhizosphere of the soybean (Glycine max (L.) Merr), grown under different photoperiod duration were investigated. A short-day soybean cultivar Clark was selected for the study; it was exposed to a long natural day (16 hours – control) and a short day (9 hours – test). The short day was created by darkening the plants with light-tight chambers for three weeks from 5 p.m. to 9 a.m. the next day. The field experiment was carried out at the experimental site of the Department of Physiology and Biochemistry of Plants and Microorganisms of V.N. Karazin Kharkiv National University, located in the Botanical garden of the University. Soil samples from the soybean rhizosphere were taken at the budding phase; the bacteria were isolated in a nitrogen-depleted medium. We studied cultural characteristics of bacteria (Gram stain, bacterial morphology, mobility, type of respiration, oxidase and catalase positivity) and their physiological and biochemical properties (the capability of proteolysis and nitrate reduction). A greater variety of bacteria in terms of cultural properties was isolated from the rhizosphere of soybean grown under long-day conditions. Probably, this is due to the higher intensity of root exudate excretion (chemoattagative factors) during the long day which is caused by different metabolic intensities at various photoperiod lengths. The highest number of isolates with proteolytic activity was observed in bacteria under long-day conditions. This property is considered to have a significant impact on the mineral nutrition of plants. Analysis of literature data showed that the higher amount of protein is accumulated in soybean leaves during the long day as a result of intensification of nitrogen nutrition provided by bacteria capable of proteolysis. Under conditions of a short day, a higher number of isolates capable of nitrate reduction was observed. A decrease in the number of isolates capable of nitrate reduction under a long-day condition can be explained by the possible repression of assimilative nitrate reductase by a large amount of ammonium formed during the ammonification of organic substances. Thus, the obtained results suggest that the photoperiod duration can determine physiological and biochemical properties of the rhizosphere microbiota of the plants sensitive to this factor.

TECHNOLOGICAL ALTERNATIVE FOR POTATO GROWING IN THE MOSCOW REGION
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, SERGEEVA NATALIA V.
Published: November 2022

Due to the need to replace worn-out mechanization tools with more modern high-performance brands, the search for alternative technologies for growing potatoes is rather relevant. Tha author made a comparative analysis of the production efficiency of the ridge-band and ridge technologies of potato cultivation for CJSC Lenin State Farm in the Moscow Region. The area of potato cultivation of the “Pirol” variety was 400 hectares. With the ridge-band technology, the main and pre-sowing tillage was carried out by the MTZ 1025 and K744R1 tractors, while ZA1500 was used for fertilization. The PLN-5-35 plow and a KSS-9 cultivator were used as tillage tools. When shifting to the ridge technology of potato cultivation, alternative means of mechanization can be considered. Tractors MTZ 1025 and K744R1 are proposed to be replaced by John Deere 8295R. During autumn tillage, plowing was replaced by deep loosening, carried out by the Digger N Fert + COMPACT deep loosener with the simultaneous application of complex fertilizers. The GL 430 was chosen as the sowing machine instead of the energy-saturated Grimme VL20 KLZ machine. Potato harvesting is proposed to be carried out with a Ventor 4150 self-propelled harvester, which is less productive than the DR-1500, but more fuel efficient; moreover, it cuts the tops while harvesting. The proposed measures made it possible to reduce the production cost of one centner by 10.8% or by 33.5 rubles per 100 kg, increase profit by 16.0% and production profitability by 9.8%, thus reaching 43.7%. The practice of using new machines exemplified by this enterprise can be useful for other potato farms operating in the Non-Chernozem Zone of Russia.
INFLUENCE OF ENVIRONMENTAL FACTORS ON POTATO YIELD
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, STAROVOITOV VIKTOR I.
Published: November 2022

Favourable temperature, aeration, and moisture conditions must be maintained in the tuber nest area to obtain a good potato crop. To develop the theoretical prerequisites and principles of designing the environment for growing potatoes, the authors conducted studies on sod-podzolic sandy loam soil at Lorch Potato Research Center in 2019-2020. The work aimed to study the influence of the complex application of environmental factors, such as moisture-saving superabsorbent polymers Aquasin (Agro) and the width of row spacing on the main agrophysical parameters of the soil and the yield of tubers when optimizing environmental formation in potato growing technology. The field experience tab, records, and observations were carried out in accordance with the requirements of the field experiment methodology and the potato research methododology. The experiment scheme included a variation of three parameters: the Meteor (early) and Favorit (medium-ripening) varieties; row spacing of 120 + 30 cm (for beds) and 75 cm (for ridges); application rates of superabsorbent polymers of 0.200 and 400 kg/ha in the first treatment. The experiment was laid according to the scheme by the method of systematic plot arrangement in a fourfold repetition. The experiment plot area was 21 m2. It was experimentally found that increasing the row-spacing and introducing SAP improved medium formation components in the tuber nest zone: the soil temperature decreased by 0.3°C; soil humidity increased from 47.4% to 59.2% of limiting field moisture capacity; values of soil hardness decreased by 2.7…11.0 kg/cm2. The crop capacity of the early potato Meteor varieties increased from 30.7 t/ha (in the variant with the ridging technology without application of superabsorbing polymers) up to 37.7 t/ha (in the variant with the ridging technology and a SAP application rate of 400 kg/ha); the crop capacity of the middle-season Favorit variety has increased from 32.3 to 39.6 t/ha, respectively. The autors conclude that the SAP application in combination with the ridge technology is a promising method.
MATHEMATICAL RELATIONSHIPS USED FOR DETERMINING COW BARN DIMENSIONS
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, GORDEEV VLADISLAV V
Published: November 2022

When designing new livestock farms, it is important to introduce the proper space-planning solutions in cow barns and technological solutions for major production processes. This task requires the development of mathematical relationships. The study presents the mathematical relationships for determining the dimensions of a cow barn for loose cubicle housing of animals using three options for the location of cubicles (technological modules). Each mathematical relationship takes into account several factors. They include the number of cows in the group; parameters of the technological module depending on the live weight of cows (the dimensions of cubicles and alleys); selection of the width of a feed table, a manure removal channel and a cow traffic alley depending on the adopted technological solutions. Determining the overall barn size makes it easier to compare different options of spatial solutions for the loose cubicle housing in terms of financial costs and animal comfort. It also allows selecting an option best suited for specific farm conditions at the stage of preparing the design assignment (basis). The proposed relationships can be used in designing algorithms of dairy farms.
INTENSIFYING THE PROCESS OF CLEANING PARTS IN SUBMERSIBLE WASHING MACHINES
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, PETRIK DMITRY Yu.
Published: November 2022

An analysis of the working conditions of agricultural machinery showed that the main contaminants of parts include a combination of soil residues with plant and other organic materials and a mixture of petroleum products of various origins. To identify the most efficient and cost-effective mode for cleaning parts, the authors conducted an experiment that takes into account three factors: the duration of washing, the temperature of the washing solution, and the concentration of the aqueous solution of detergent components. The optimization criterion is the amount of washed out contamination. The authors designed a matrix for the implementation of the full-factorial experiment plan. Samples in the form of a square tube with a size of 50 × 50 mm and a length of 50 mm were cleaned using a submersible washing machine in the form of a small-sized ultrasonic bath Specos V-100. A solution consisting of sodium carbonate and a mixture of surfactants in a ratio of 9:1 was used as a detergent. The modes of ultrasonic cleaning were changed in accordance with the variation of three factors: cleaning duration – from 5 to 15 minutes, washing solution temperature – from 40 to 80°C; concentration of the aqueous solution of detergent components – from 5 to 25 g/l. The reproducibility of the experimental results was confirmed using the Cochran test. The significance of the regression coefficients was determined using Student’s t-test. The model was validated using the Fisher criterion. Based on the regression equation, the authors determined response surfaces, in which the dependences are extremely close to linear. It is concluded that with washing duration of 12 minutes, a washing solution temperature of 70°С, and a concentration of the aqueous solution of detergent components of 20 g/l, the amount of washed out contamination is maximum.

The overcapacity of vehicle numbers is one of the significant causes of the traffic congestion problem on Indonesia roadways. The government applies a One-way system (SSA) as one proposed solution to unravel the congestion. However, several congestion points are still found during the SSA implementation. Thus, this research offers an alternative method to detect congestion using IoT technology. The system automatically enumerates the number, classifies the type, and computes the speed averages of vehicles to identify the severity of congestion based on the Indonesian Highway Capacity Manual (IHCM) published by the Ministry of Public Works 2014. We utilize ultrasonic sensors to detect the vehicles and send the data to the server in real time. The research successfully develops an IoT system for traffic congestion detection. Communication between nodes and API can be done well. Data exchange involving encryption and decryption with AES-256 is successfully done. The website application developed in this research successfully show the severity level of the congestion and their vehicle numbers. The average accuracy of the system is 78,97%. The system detected more vehicles than actual numbers due to the misreading value of the sensors.

Pertanian berkelanjutan merupakan komponen penting dalam pencapaian Sustainable Development Goals (SDGs). Pengukuran keberlanjutan pertanian mutlak dilakukan untuk lebih memahami kondisi saat ini, mengidentifikasi tren, menetapkan target, memantau kemajuan, dan membandingkan kinerja antar wilayah. Penelitian tentang keberlanjutan pertanian di Indonesia lebih banyak dilakukan pada level usaha tani atau lokal. Indonesia belum memiliki indikator pertanian berkelanjutan yang menjadi tolok ukur penilaian pertanian berkelanjutan pada level regional/provinsi/nasional. Hal ini disebabkan karena begitu kompleksnya penilaian yang perlu dilakukan untuk mendapatkan hasil yang baik untuk penilaian pada level regional dan nasional. Indikator yang dapat diukur mengenai kelestarian lingkungan pertanian, dengan tujuan meminimalkan dampak lingkungan dari pertanian, merupakan alat penting untuk membantu menggerakkan dunia menuju masa depan pangan yang berkelanjutan. Indikator memungkinkan pembuat kebijakan, petani, bisnis, dan masyarakat sipil untuk lebih memahami kondisi saat ini, mengidentifikasi trend, menetapkan target, memantau kemajuan, dan membandingkan kinerja antar wilayah dan negara.

Infeksi SARS-CoV-2 dapat menyebabkan disregulasi respons imunitas tubuh yang menimbulkan sekresi sitokin proinflamasi yang berlebihan, menyebabkan kondisi yang disebut sebagai badai sitokin. Badai sitokin ini memiliki peran penting dalam progresi penyakit COVID-19 karena dapat menyebabkan disfungsi multi organ, gangguan koagulasi, dan kematian. Sitokin proinflamasi yang paling banyak mengalami peningkatan selama badai sitokin pada pasien COVID-19 adalah IL-6. Dari pengetahuan ini, peneliti mulai mencari tahu kemungkinan digunakannya terapi inhibisi IL-6 sebagai bagian dari tata laksana COVID-19. Tiga macam terapi inhibisi IL-6 yang sedang diteliti adalah inhibitor reseptor IL-6, antagonis IL-6, dan inhibitor JAK. Ketiga agen terapi inhibisi IL-6 ini terbukti dapat memperbaiki klinis dan mengurangi mortalitas pasien COVID-19 dengan gejala berat. Akan tetapi, pemberian terapi inhibisi IL-6 masih belum memberikan hasil yang konsisten pada pasien COVID-19 yang disertai dengan gejala kritis sehingga pemberian pada kelompok ini harus lebih hati-hati. Oleh karena itu, penelitian lebih lanjut mengenai efektivitas dan keamanan terapi ini harus tetap dilakukan.

Steven-Johnson Syndrome (SJS) merupakan suatu reaksi mukokutan akut yang yang ditandai dengan nekrosis luas dan eksfoliasi dari lapisan epidermal. Etiologi atau pemicu tersering pada kasus SJS adalah obat ataupun metabolitnya, diikuti oleh infeksi dan idiopatik. Obat-obatan tersering yang memicu terjadinya SJS antara lain sulfonamide, non-steroidal anti-inflammatory drugs (NSAID) seperti derivat oxicam, antifungal imidazole, cephalosporin, antikonvulsan, allopurinol, broad- spectrum bactericidal agents, dan regimen Highly Active Anti Retroviral Therapy (HAART). Didapatkan kasus seorang wanita berusia 42 tahun dengan keluhan timbul lepuhan pada bibir dan kelopak mata serta bercak kemerahan pada badan, kedua tangan dan kaki. Keluhan tersebut mulai timbul setelah pasien mengonsumsi obat Piroxicam. Didapatkan lesi pada area dahi, kelopak mata, bibir dan leher berupa lesi makula-patch eritem, berbentuk ireguler, berbatas tidak tegas, dengan ukuran lenticular-plakat, dengan susunan diskret-konfulens, distribusi regional disertai dengan erosi serta krusta hemoragik. lesi pada perut, kedua tangan dan kaki berupa makula – patch eritem dengan purpura di bagian sentral berbentuk bulat dan ireguler, dengan ukuran milier – plakat, dengan susunan diskret-konfluens dan distribusi generalisata dengan erosi dan krusta berwarna coklat kehitaman pada perut kuadran kiri atas dan erosi serta krusta hemoragik pada lengan kiri atas. Pasien didiagnosis kerja dengan Steven-Johnson Syndrome yang kemudian meninggal akibat aspirasi pada hari ke 9. Adanya faktor pencetus serta lesi kulit dan mukosa yang mengarah pada SJS dapat mempercepat pengambilan keputusan klinis sehingga tatalaksana lebih cepat diberikan.

Malaria is endemic in Brazilian Amazonia, accounting for 99% of national cases. Amazonian forest peoples (both Indigenous and traditional) understand and treat the disease based on their knowledge, rituals, and religion. In recent decades, biomedical health coverage has expanded in the region, with implications for local perceptions and practices to prevent, treat, and recover from malaria. This paper attempts to understand how the expansion of biomedical healthcare among forest peoples interacts with their ethnomedicinal knowledge. Our results clearly indicate that most of our research participants in rural northwest Amazonia believe that malaria has a variety of causes, forms of prevention, and treatment. We also found that these beliefs are shaped by both local knowledge (including Indigenous) and some technical concepts of biomedicine. Consequently, new approaches and practices in healthcare need to be developed which consider forest peoples' perceptions and understanding.

Abstract

This study aims to determine the effect of miana leaf extract as a sanitizing agent on the mortality and hatchability of native chicken eggs and to find other alternatives to chemical disinfectants that can be used as natural antimicrobials in the cleaning process of hatching eggs. This study used 80 eggs that had been selected and came from a farm owned by Mr. Abu Hiri in Wayame Village, Dusun Waringin Cap. This study was analyzed using the t-test (Independent Sample t-Test) to compare the results of leaf extract sanitation and fumigation. The results showed that there was no significant difference between sanitation using miana leaf extract against, mortality and hatchability of native chicken eggs, which means that miana leaf extract can be used as a chemical substitute for sanitation.
Uncertainty Sequence Modeling Approach for Safe and Effective Autonomous Driving

Deep reinforcement learning(RL) is an end-to-end data-driven control method that is widely used in the autonomous driving domain. However, conventional RL approaches have difficulties in applying it to autonomous driving tasks due to problems such as inefficiency, instability, and uncertainty. These issues play an important role in the autonomous driving domain. Although recent studies have attempted to solve these problems, they are computationally expensive and rely on special assumptions. In this paper, we propose a new algorithm MCDT that considers inefficiency, instability, and uncertainty by introducing a method called uncertainty sequence modeling to autonomous driving domain. The sequence modeling method, which views reinforcement learning as a decision making generation problem to obtain high rewards, avoids the disadvantages of exiting studies and guarantees efficiency, stability and also considers safety by integrating uncertainty estimation techniques. The proposed method was tested in the OpenAI Gym CarRacing environment, and the experimental results show that the MCDT algorithm provides efficient, stable and safe performance compared to the existing reinforcement learning method.
