Published: May 2023

Abstract
The behaviour of women in providing, obtaining, and utilizing food can determine the status of household food security. Consumption of diverse food including animal protein is very important to prevent stunting. The level of energy consumption which is still below the national standard and the low consumption of animal protein by the people of West Nusa Tenggara Province contribute to the high number of stunting cases in West Nusa Tenggara Province, especially West Lombok Regency. To reduce it, the Government of West Lombok has provided guidance to coastal communities through extension activities on optimizing the marketing and processing of fish caught to fisherwomen. This study aims to find out about the role of extension workers in supporting household food security, analyse the influence of the role of extension workers on the behaviour of women fishermen and analyse the effect of women’s behaviour on the status of household food security. The research was conducted in Batu Layar District, in Meninting Village and Senteluk Village and Lembar District, Sheet Village and South Sheet Village. The research was conducted using an explanatory survey method with data collection through interviews with 60 respondents, observations, and in-depth interviews with several fisherwomen informants and key informant. Then the data was analysed by regression analysis. The results of the analysis indicate that the higher the role of the extension worker will be able to change the behaviour of fisherwomen, and changes in the behaviour of fisherwomen will improve the status of household food security. Thus, increasing the competence of extension workers must be comprehensive, not only focusing on the production aspect but also on the importance of food and nutrition aspects. Then, it is necessary to encourage an increase in the role of extension workers in conducting counselling and mentoring to change the behaviour of fisherwomen in processing, selecting, providing, and distributing diverse and nutritious food to each household member.

Abstract
The study was aimed to i) analyze the economic value and feasibility of the introduction of chili proliga technology, and ii) analyze farmers’ responses to the introduction of chili proliga technology. The study was conducted in Rembang Regency, from August 2021 to February 2022. Two treatments were involved: i) chili farming with the introduction of chili proliga technology, and ii) existing chili farming. The economic value and feasibility were analyzed quantitatively by calculating i) cost of farming, ii) economic feasibility, and iii) partial analysis of technological changes. Farmers’ responses were analyzed based on i) level of understanding, ii) level of difficulty, and iii) level of willingness to adopt chili proliga technology. The study’s results showed that the introduction of chili proliga technology was able to increase profits by 392.21% with an R/C value of 2.3. The benefits obtained by farmers from technological changes received an MBCR of 3.07, meaning that every additional cost of IDR 100,000 brought an additional profit of IDR 307,000. Farmers’ responses to chili proliga technology show that i) farmers “understand” that technology ii) farmers find it easy to apply that technology, and iii) farmers are “willing to adopt” that technology.

Abstract
Tailings of ex-gold mines leave several environmental damage problems. Environmental damage causes disruption of microorganisms including bacteria. The revegetation of ex-gold mine tailings in Menjalin sub-district, Landak district, West Kalimantan has begun by local communities using agricultural crops. Women as farmers have an important role in the tailing revegetation process using agricultural crops. Therefore, women can help improve the tailings ecosystem as well as the family economy. The objective of the study was to detect the presence and density of bacterial populations in the rhizosphere of the revegetation crops. The research was conducted by survey method. Soil samples were taken compositely from the rhizosphere of four species of agricultural crops cultivated in tailings, i.e: Capsicum frutescens L., Solanum melongena, Ipomoea batatas L., and Manihot utilissima. The results showed that soil bacteria found growing well in the rhizospheres of four species crops. Two genera of bacteria were found in the tailing rhizosphere of ex-gold mine in Menjalin sub-district, namely Azotobacter and Pseudomonas. The bacterial population density in the rhizosphere of M. utilissima was significantly the highest. Meanwhile, the bacterial population density in the rhizosphere of C. frutescens, I. batatas, and S. melongena did not differ in the medium category. Further investigation found that the bacterial population in the rhizosphere of M. utilissima was 126.8 – 217 times denser than the other three crop species.

Published: May 2023

Abstract
The sustainability of vegetable and fruit development model in the food estate area depends on the ability to cultivate commodities demanded by the market in a chain of efficient marketing. The purpose of this study is to probe consumer behaviour regarding the availability of fruit and vegetable commodities, the problems associated with it, and to analyse potential for developing technological innovations in the village of Belanti Siam. This research was conducted in 2020 via interviews with 33 respondents, utilizing analysis of consumer preferences and qualitative descriptive analysis methods. The results show that the population met the needs of fruit and vegetables from harvesting and purchasing. The availability of those commodities is more consistent if they are self-produced since the farmers’ can do their own quality and cost-control. The integration of rice commodities with vegetables and fruit is expected to overcome the constraints of a shortage caused by logistical challenges and poor quality due to relying only on outsourcing from outside the region. Increased income of farmers and marketers through value chain enhancement created from the ability to meet product requirements according to market needs, maintained quality and cost efficiency has the potential to develop the adoption of horticultural technology innovations in a sustainable manner in food estates.

Abstract
Pigs are livestock that has a significant meaning for the local Papuan community. Pig rearing is done traditionally from generation to generation without providing technical input to increase productivity. Therefore, this study aimed to study the profile of pig farms that determine the production of pigs. This research was conducted in the Manokwari district. A semi-structured questionnaire was employed for data collection and supported by key informant group discussions. Respondents were sampled using purposive random sampling under predetermined criteria and then randomized. The percentage of each variable observed was done to know pig farming in Manokwari. The results of the analysis showed that the highest percentage of pig farmers as follows age over 50 years old (56%); the education of farmers is high school (44%); off-farm income came from the private sector (40%); pig ownership dominated by the female for all level (starter, grower and finisher). Farmers fed the pigs with a mixture of raw materials dominated by vegetables and tofu dregs.

Published: May 2023

Abstract
Research on reinforcing airplane structures while reducing their weight by employing sustainable materials is currently challenging. In this study, damage mechanisms, mechanical characteristics, and failure behavior of laminates made of plain-woven glass fiber/epoxy and Glass Fiber Reinforced Polymer (GFRP) with sea shell filler under low-velocity impact static loading conditions are experimentally investigated. The bi-directional GFRP type E-glass laminates with 10 plies and a total thickness of 3.35 mm are created by hand lay-up process using an epoxy matrix. Comparing GFRP with an effective ratio of sea shell filler of 5% under various impact loading, composites are characterized in accordance with ASTM standards to assess the progressive damage and failure of GFRP composite. The findings of the experiment indicate that GFRP with seashell filler composites outperforms GFRP composites in terms of impact strength, outstanding flexural strength, and tensile strength. The findings show that adding seashell filler to GFRP increased the composite’s ability to sustain various impact loads. The sample with seashell infill has a drop weight impact that is 25.26% lower than GFRP. Moreover, the flexural test demonstrated a 59.6% increase in bending over GFRP. Seashell filler outperformed GFRP in the longitudinal strength test by 33.12%, according to the results of the tensile test. Finally, the compression after impact test (CAI) manifested a remarkable increase in transverse strength by 78.23%.

Published: May 2023

Abstract
The rapid development of emerging domains, such as the Internet of Things and wearable technologies, necessitates the development of flexible, stretchable, and non-toxic devices that can be manufactured at an ultra-low cost. Printed electronics has emerged as a viable solution by offering not only the aforementioned features but also a high degree of customization, which enables the personalization of products and facilitates the low-cost product development process even in small batches. In the context of printed electronics, printed neuromorphic circuits offer highly customized and bespoke realization of artificial neural networks to achieve desired functionality with very small number of hardware components. However, since analog components are utilized, the performance of printed neuromorphic circuits can be influenced by various factors. In this work, we focus on three main factors that perturb the circuit output from the designed values, namely, variations due to printing errors, aging effects of printed resistors, and input variations originating from sensing uncertainty. In the described approach, these variations are taken into account during the design (training) to ensure the dependability of the printed neuromorphic circuits. With this approach, the expected accuracy and the robustness of printed neural networks can be increased by 27% and 74%, respectively. Moreover, the ablation study suggests that, aging effect and printing variation may have similar effects on the functionality of printed neural networks. In contrast, the impact of sensing uncertainty on printed neural networks is almost orthogonal to aging and printing variations.
Environmental threats to beekeeping in the Western Balkan countries - beekeepers’ perceptions
Authors: Šarić Bojana Bekić , Muça Etleva Dashi , Subić Jonel , Džimrevska Irena , Rašić Slađan 
Published: May 2023

Abstract
The subject of the paper refers to the research on beekeepers’ perceptions of environmental threats to beekeeping in the Western Balkan region. The following environmental threats were supposed to be the most pronounced: cutting of melliferous perennial plants and clearing of forests, urbanisation and environmental pollution, use of pesticides in agricultural production, pests and agents of bees’ diseases, climate changes. The aim of the research was to find out how beekeepers perceived these threats, to determine the presence of the threats and to define their intensity as well as their mutual relationship. For the purpose of this research, the authors created a structured questionnaire which was filled in by randomly selected beekeepers living in the Western Balkans. The research results show that most beekeepers in the studied area evaluated the assumed threats as strong to very strong, while the greatest percentage of beekeepers believes that climate change represents the greatest threat to beekeeping in the region. All assumed environmental threats show the same tendency, while they have the most serious effect on large apiaries with more than 150 bee colonies, located in lowland areas up to 200 meters above sea level with intensive farming. Findings of this research are important in order to adapt the current beekeeping practice in the region to more sustainable solutions, through improvement of the existing beekeeping legislation and advisory services.

Published: May 2023

Abstract
Halogenated MXenes have been experimentally demonstrated to be promising two-dimensional materials for a wide range of applicability. However, their physicochemical properties are largely unknown at the atomic level. In this study, we applied density functional theory (DFT) to theoretically investigate the halogenation effects on the structural, electronic, and mechanical characteristics of Ti3C2, which is the most studied MXene material. Three atomic configurations with different adsorption sites for four kinds of halogen terminals (fluorine, chlorine, bromine, and iodine) were considered. Our DFT results reveal that the adsorption site of terminals has a considerable impact on the properties of MXene. This can be ascribed to the different coordination environments of the surface Ti atoms, which change d-orbital splitting configurations of surface Ti atoms and the stabilities of systems. According to the density of states, crystal orbital Hamilton population, and charge analyses, all the considered halogenated MXenes are metallic. The electronic and mechanical properties of the halogenated MXenes are strongly dependent on the electronegativity of the halogen terminal group. The Ti–F bond has more ionic characteristics, which causes Ti3C2F2 mechanically behave in a more ductile manner. Our DFT results, therefore, suggest that the physicochemical properties of MXenes can be tuned for practical applications by selecting specific halogen terminal groups.
The best answer? Justice Nelson’s concurrence in Dred Scott v. Sandford
Authors: Meyer William B 
Published: May 2023

Abstract
The merits, comparative and absolute, of Justice Samuel Nelson’s concurring opinion in the Dred Scott case of 1857 have not been adequately recognized. Nelson took ground that was legally more secure at the time than did either Chief Justice Taney, in his opinion for the Court, or the dissenters, Justices McLean and Curtis. Refusing to follow Taney’s ill-supported denials of Black citizenship and Congressional power over the Territories, he also understood better than the dissenters what conflict-of-laws doctrine, the precedent of Swift v. Tyson (1842), and the law of marriage and divorce implied for Scott. Nelson’s opinion carried a mix of political implications, but it possessed more credibility than the other opinions in the case for its solid grounding in accepted legal principles and freedom from overt partisanship.
Wood dust in France. Trends in the population of exposed workers between 1982 and 2017 based on a job-exposure matrix assessment
Authors: Garras Loïc , Ducamp Stéphane , Houot Marie-Tülin , Pilorget Corinne 
Published: May 2023

Abstract

Objective
Many occupations and industries use wood as a raw material and wood dust is a well-known carcinogen. This study presents trends in occupational exposure to wood dust for all workers (employees and self-employed workers) in France between 1982 and 2017 and focuses on the exposed workers in 2017.

Methods
Exposures to this carcinogen were assessed using the Matgéné job-exposure matrix. Trends in the prevalence and proportion of exposure over the study period were estimated by linking the matrix with population data from the 1982, 1990, 1999, 2007, and 2017 censuses and are described for selected industry groups.

Results
The number of exposed workers to wood dust has decreased significantly over the last 40 years, from 466,900 potentially exposed workers in 1982 to 305,000 workers in 2017. The proportion of exposed workers has also decreased over time, although not uniformly across industries. Increases in the proportion of exposed workers are observed in certain industries, such as “Sawmilling and logging” (from 61.2% to 73.6% over the period for men) and “Finishing of sale premises” (from 3.3% to 6.2% for women).

Conclusion
This article is the first to describe occupational exposure to wood dust in France for all workers and to follow its evolution over the last 40 years. Occupations and industries still at risk in 2017 are also described with the aim of helping to improve prevention policies.
Deep single-cell RNA-seq data clustering with graph prototypical contrastive learning
Authors: Lee Junseok , Kim Sungwon , Hyun Dongmin , Lee Namkyeong , Kim Yejin , Park Chanyoung 
Published: May 2023

Abstract

Motivation
Single-cell RNA sequencing enables researchers to study cellular heterogeneity at single-cell level. To this end, identifying cell types of cells with clustering techniques becomes an important task for downstream analysis. However, challenges of scRNA-seq data such as pervasive dropout phenomena hinder obtaining robust clustering outputs. Although existing studies try to alleviate these problems, they fall short of fully leveraging the relationship information and mainly rely on reconstruction-based losses that highly depend on the data quality, which is sometimes noisy.

Results
This work proposes a graph-based prototypical contrastive learning method, named scGPCL. Specifically, scGPCL encodes the cell representations using Graph Neural Networks on cell–gene graph that captures the relational information inherent in scRNA-seq data and introduces prototypical contrastive learning to learn cell representations by pushing apart semantically dissimilar pairs and pulling together similar ones. Through extensive experiments on both simulated and real scRNA-seq data, we demonstrate the effectiveness and efficiency of scGPCL.

Published: May 2023

Abstract

Summary
We present pygenomics, a Python package for working with genomic intervals and bioinformatic data files. The package implements interval operations, provides both API and CLI, and supports reading and writing data in widely used bioinformatic formats, including BAM, BED, GFF3, and VCF. The source code of pygenomics is provided with in-source documentation and type annotations and adheres to the functional programming paradigm. These features facilitate seamless integration of pygenomics routines into scripts and pipelines. The package is implemented in pure Python using its standard library only and contains the property-based testing framework. Comparison of pygenomics with other Python bioinformatic packages with relation to features and performance is presented. The performance comparison covers operations with genomic intervals, read alignments, and genomic variants and demonstrates that pygenomics is suitable for computationally effective analysis.
