Blazing Ballet Girls and Flannelette Shrouds: Fabric, Fire, and Fear in the Long Nineteenth Century
Authors: Matthews David Alison
Published: March 2024

Fire was one of the most terrifying dangers for women and children in the nineteenth century. Many burned to death in highly inflammable clothing. A new, sylph-like Romantic feminine ideal in dress arose in tandem with the gas lighting that illuminated the light white cottons and almost “immaterial” materials that became fashionable during the Neoclassical period. These textiles included machine-woven gauze, tulle, and tarlatane, and they put working-class ballet dancers pirouetting near gas footlamps at particular risk. French prima ballerina Emma Livry died when her tutu caught on fire, and the charred remains of her costume are still preserved at the Musée-bibliothèque de l’Opéra in Paris. In the late 1870s, another popular, mass-produced fabric, flannelette, was sold as a cheap, washable substitute for woolen flannel. Yet the soft, raised, furry “nap” of the fabric that kept children warm set them ablaze because most working-class homes lacked proper fire guards. In response to the dangers ushered in by these new products, textile manufacturers and chemists attempted to flameproof them, but these fireproofed fabrics were not widely adopted. This article maps emotional responses to clothing accidents, tracing a shift from the romantic individualization of early nineteenth-century fire deaths to the anonymous statistical analysis and detached scientific observation of accidents in the late nineteenth century. It considers the role of the researcher’s and curator’s own emotional reactions to the material remains of disturbing garments that still bear the traces of physical trauma in their very fibers.
THE EXPERIENCE OF OECD EDUCATION STATISTICS FORMATION: ITS RELEVANCE FOR VOCATIONAL EDUCATION AND TRAINING IN UKRAINE
Authors:   National Aviation University, Belinska Ganna
Published: March 2024

The article discusses certain issues related to the collection of statistical data in the field of vocational education and training (VET) in Ukraine. It was found that for the continuous monitoring of educational activities at all levels of education in general and the VET in particular, an insufficient amount of information is collected (especially regarding the financial aspect). For comparison, the example of the OECD is considered, as an organization with significant experience in the formation of informative educational indicators. The author found that the approach to the formation of educational indicators in the OECD countries differs significantly, meaning the calculation of all indicators is aimed at disclosing information about the receipt and expenditure of funds in VET institutions, their sources, and the structure of expenses by category and per student. That is, all indicators are calculated for the purpose of evaluating the effectiveness of educational institutions. As a result, the indicators that highlight information about teachers are also primarily focused on disclosing information that is indirectly related to finances: expenses for teachers' wages by various sections, etc. The Ukrainian forms of VET institutions that are submitted to the Ministry of Education and Science of Ukraine (primarily Forms No. 1, 2, and 3 of VET) are oriented more towards the calculation of the physical presence of teaching staff and students and their gradation by age, gender, involvement in the learning process, etc. It was concluded that such information is incomplete and does not make it possible to assess the effectiveness of the educational institution.

The use of benzene as a solvent in the manufacturing industry can be dangerous because it is volatile, toxic, and carcinogenic. Exposure to benzene occurs through inhalation of the chemical in the air, which can enter the human body through the respiratory system. The levels of trans, trans-Muconic Acid (tt-MA), which is used to metabolize benzene, can be affected by the amount of exposure to the chemical. This study aims to determine the differences in exposure to benzene in the air by measuring the tt-MA indicators and liver function of workers in the manufacturing industry. This research uses an observational and cross-sectional approach, with a population of 158 employees from both administration and production units. The sample size for the study is 16 respondents, selected using the consecutive sampling technique. The research instrument uses a questionnaire and examines urine samples using the in-house method. Blood samples are examined using IFCC 37 C. The data is processed using the independent-sample t-test and Pearson correlation. The results show that the level of benzene in the air is below the threshold of 0.5 ppm. However, there is a significant difference in the results of tt-MA and SGOT (p<0.05), while the levels of SGPT (p>0.05) show no significant differences. In conclusion, there are differences in the tt-MA and SGOT exposure levels between workers in the production and toxicity units, while SGPT does not show significant differences. It is recommended that the industry maximizes the use of local exhaust ventilation and prohibits smoking.

The ability of pregnant women to detect early high-risk pregnancies is still below average which is one of the causes of complications that can endanger the well-being of the mother and fetus. Family involvement and other social sources of support in the perinatal period are associated with the detection and reduction of pregnancy risk factors. Approach to families in early dedetermination of pregnancy risk can be done with Family Center Maternity Care (FCMC). FCMC is care designed to meet the informational, social, emotional, comfort, and support needs of normal pregnant women during pregnancy and childbirth. The purpose of this study was to determine the determinants of early detection factors for pregnant women with family-based risk with FCMC. This type of research is quantitative and non-experimental with an analytical observational design through a cross-sectional approach.  The population in this study was all pregnant women who experienced risk factors in the Kedungwuni I, Kedungwuni II, Bojong Health Center Area as many as 103 pregnant women. The sampling technique used is the Total Population. The results of this study show that there is a positive and statistically significant relationship of knowledge with the implementation of early detection. Pregnant women who have good knowledge have a likelihood of carrying out early detection of pregnancy risk well by 3,193 times higher than respondents with less knowledge (OR=3,193; CI 95%=1.123-9.078; p=0.029). It is hoped that health workers, especially midwives, can involve their families, especially for early detection of the risk of pregnant women so that pregnant women get optimal health services.

Published: March 2024

The work in hand presents the elaboration of CuO thin films using a home-made spray pyrolysis technique at room atmosphere. The films were synthesized on preheated glass substrate at 450 °C. The source solution molarity was varied from 0.025 to 0.1 mol/L. The films were characterized by employing X-Ray Diffraction technique, UV-Vis-NIR spectrophotometry, Scanning Electron Microscope imagery, Energy Dispersive Spectroscopy, and four-points probe techniques. The X-ray diffraction analysis confirmed that all films are polycrystalline with a preferred orientation along the plane (−111) of the monoclinic crystal structure phase of tenorite (CuO). The SEM images showed a homogeneous and smooth surface. Crystallinity and grain size were improved. The rise of solution concentration induced a reduction of transmittance and reflectance in the visible region. The energy gap, the absorption coefficient, the extinction coefficient, refractive index, dielectric constant (ԑr and ԑi) and loss energy were estimated from transmittance and reflectance data. The gap energy decreases from 2.72 to 2.56 eV. The film deposited for 0.025 mol/L exhibits the highest real part of the dielectric constant (ԑr ~ 17). The film resistivity which is in order of 102 Ω cm decreases with the increase of molar concentration. The estimated dielectric constant indicated that the resulting CuO thin films could be used as dielectric layers for optoelectronic devices working in Vis-NIR region of radiation. Furthermore, the relatively high band gap, high absorption coefficient and high conductivity of the film obtained at 0.075 mol/L, make them good candidates as absorption layers in solar cells applications.

The procedure used in the research is 4D by Thiagarajan and in the limited test a onegroup pretest-posttest research design was carried out. The development of teaching materials in the study refers to Thiangarajan's 4D model (1974) which consists of 4 stages, namely Define, Design, Develop, and Disseminate, but because in this development research using limited product trials, the research stages are carried out in sequence until the Develop stage (Thiagarajan, Sammel, & Sommel, 1974). This trial design used a one group pretest-posttest design. In this design, two tests were carried out, namely before being given treatment called pretest and after treatment called posttest.The instrument used is a media validation sheet for the validity of Electronic LKPD. In one of the public high schools in Mojokerto, metacognitive skills are very low at 20%. Based on interviews with chemistry teachers, it was found that the chemistry learning model in class often applies lecture models, discussions, so that students are less actively involved in learning and teachers have never tested students' metacognitive skills. This has an impact on the metacognitive skills of students in chemistry lessons are less than satisfactory, especially in petroleum material. The results of product validation consist of the mode on the content criteria getting validity 4 and the mode on the construct criteria getting validity 4 with both criteria being very valid. So that the Electronic LKPD developed is valid to improve students' metacognitive skills through the Problem Based Learning (PBL) model on Petroleum Material.

Mercury Metal Absorption using Ethylene Diamine Tetraacetic Acid Intercalated Carbon
Authors: Indah Dahlia Rosma , Hatimah Husnul
Published: March 2024

Silver craft waste contains hazardous metals, one of which is mercury metal. If high concentrations of mercury waste are disposed of without treatment, this waste seeps into the soil and pollutes residential water sources because mercury metal is difficult to decompose. Mercury poisoning can cause nerve reactions such as difficulty speaking, blurred vision, muscle weakness, paralysis, impaired sense of taste, and shortness of breath. This research was conducted as an effort to reduce mercury metal levels in silver craft waste in Central Lombok Regency. The method of waste treatment is by adsorption method utilizing carbon bagasse modified with EDTA. The first step is to first determine the level of mercury metal in silver craft wastewater in Central Lombok. Furthermore, wastewater is contacted with EDTA-intercalated bagasse carbon. Making intercalated carbon bagasse consists of 3 stages, namely first dehydration by burning bagasse until it turns into carbon, second carbonation is heating temperature 500ºC, carbon results are sifted 100-200 mesh and third, intercalation is by soaking 100 grams of carbon in 250 mL EDTA solution 10% stirred for 6 hours. After that the carbon is dried at a temperature of 50ºC. A total of 2 grams of intercalated bagasse carbon that has been made is put into 25 mL of wastewater samples. The sample was stirred at contact time variations of 30, 60, 90, 120 and 150 minutes using a stirer. The optimum time obtained is used to calculate the efficiency of reducing mercury metal levels, namely calculating the difference in mercury metal levels before adsorption and after adsorption using EDTA intercalated carbon baggase. Mercury metal levels were analyzed using an Atomic Absorption Spectrophotometer (SSA). From the study, it was found that the mercury metal content in the sample was 50.6398 ppb. The optimum contact time in mercury metal adsorption is at a contact time of 120 minutes which results in an optimum adsorption efficiency in mercury metal of 70.55%.

Due to its low carbon content, mild steel is prone to corrosion. Therefore, corrosion inhibitors are needed to decrease the corrosive rate of mild steel. This research aims to investigate the influence of adding potassium iodide to miana leaves extract (Coleus scutellaroides (L.) Benth.) (MLE) on the corrosion rate of mild steel, identify the type of adsorption, synergistic effects and characterize the surface of mild steel both before and after the addition of potassium iodide. The weight loss method is employed to test the corrosion rate, and the type of adsorption is identified through thermodynamic calculations. Surface characterization is evaluated using Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). As potassium iodide is added, the weight loss findings show an increase in inhibitory efficiency. When potassium iodide concentration was 0.4 g/L and temperature was 30°C, the maximum inhibitory efficiency was attained, which was 92.784%. Characterization analysis indicates the interaction between potassium iodide and MLE with the surface of mild steel. This research has not been explored yet and is expected to provide information on the use of potassium iodide and MLE as environmentally friendly corrosion inhibitors.

Tomatoes are the popular fruit but having short shelf life. This fruit require some treatment to maintain it’s quality during post-harvesting. Eco-enzyme is a fermented liquid, it’s made by fermentation process of fresh waste vegetables or fruits. Previous study showed that spraying tomatoes with Eco-enzyme can maintain the shelf life of tomatoes. This study aim to observe the effect of various liquid in Eco-enzyme fermentation and it’s effect to tomatoes preservation by soaking method. The research was experiment research using quality scale of tomatoes. The Eco-enzyme was fermented using different liquid such as water, coconut water and rice rinsed water. Tomatoes were soaked with each Eco-enzyme treatment with 50% and 100% concentration of each liquid for 5 minutes then rinsed them and observed their quality for 8 days during storage process. The control treatments are non-soaked and non-rinsed tomatoes. The observation include the quality of tomatoes and the quality of Eco-enzyme. The result of this study found that modification of liquid in Eco-enzyme fermentation have different effect for tomatoes preservation. Soaking and rinsing method also have different effect for tomatoes. The best treatment for EE1 is EE1-rinse-concentration 50%, EE2 is EE2-rinse-concentration 100%, and EE3 is EE3-rinse-concentration 50%. The soaking followed rinsing was the best method for tomatoes preservation treatment using Eco-enzyme.

Los Estados y las ciencias sociales e informáticas se enfrentan a nuevas realidades que cuestionan las estrategias comunicacionales tradicionales con la ciudadanía. La pandemia de covid-19 aceleró este proceso en Argentina. Mediante un análisis de tipo cualitativo en redes, medios y contactos personales, en dos estados subnacionales (la Ciudad Autónoma de Buenos y la Provincia de Buenos Aires), se constató que el capital social de cada persona visibilizó la rapidez en el acceso a la inoculación. La amplia difusión de nuevas tecnologías (plataformas en línea y aplicaciones de telefonía móvil) enmascararon las desiguales condiciones de acceso de la población a estas herramientas. Frente a este desafío, las herramientas implementadas durante la campaña de difusión y de vacunación contra el covid-19 profundizaron el problema, en vez de proponerse como una solución.
