Archiving the Resistance: Memory and Oppositional Recordkeeping in Dystopian Fiction
Authors: Kayışcı Akkoyun Burcu
Published: June 2023

As imaginary good places located elsewhere and/or in another time, literary utopias may articulate nostalgic yearnings for an irretrievable past, but more significantly, they express socio-political discontent with the present and anticipations for the future. The role of memory is thus central in utopian configurations since they present better alternatives primarily by “remembering” and evaluating specific historical conjunctures. In line with the increasing prominence of dystopian fiction starting from the early twentieth century, issues concerning the preservation and destruction of memory have become more relevant. Authors portray how totalitarian regimes and corporations reshape or sever the links between the past, the present, and the future while defiant characters resist political oppression by forming alternative narratives. The struggle to construct personal and collective archives against the obliteration of past and present records makes recordkeeping a common theme and trope in many dystopian narratives. This paper examines the various forms of what I call “oppositional recordkeeping” in the selected major examples of the genre through theories of dystopia, memory, and the archive. The paper will conclude that authors of dystopian fiction preserve the possibility of utopian change by imagining various oppositional recordkeeping practices without overlooking the problems entailed in authority and authorship.

Toxic phthalates that can be released from food packaging into food are currently a matter of concern, affecting consumers’ health. However, in Vietnam, no studies have been published on this group of substances in food packaging and films. In this research, a method for the simultaneous determination of 7 typical phthalates, including benzyl butyl phthalate (BBP), dibutyl phthalate (DBP), di(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP), di-(2-ethylhexyl) adipate (DEHA) in food wrap samples by gas chromatography mass spectrometry (GC-MS) using internal standards has been developed and validated. The limit of detection and limit of quantification for all substances was 0.03 mg/kg and 0.10 mg/kg, respectively. The recoveries of the method were in the range of 82-105%. Relative standard deviation (RSD) ranged from 5.6 to 7.5%. The method has been applied effectively to analyze the content of phthalates in 35 food wrap samples that were collected from markets in Hanoi. Analytical results showed that ten samples were detected with phthalates, of which three samples contained DEHA exceeding the specific migration limit (SML). This study contributes to consumer health protection and advises the regulatory agency on the addition of safety regulations for PVC food wrap in particular and other food packaging materials in general.

The study aims to evaluate the degree of fat oxidation and the reuse of fried oils in fried meat and fish ball products sold in Ninh Kieu District, Can Tho City. The fat content was determined in fried products, as follows: fish balls (15 - 21%), beef balls (11 -14%), and shrimp balls (15 - 23%). Because of the difference in the fat origin of the three types of fried products, the oxidation levels of these products are also different; therefore, this is possible through parameters related to the variation of fat such as acid index, peroxide index, malondialdehyde (MDA) content. The concentration of MDA was the highest in fried fish balls, and the lowest value was in beef balls. After surveying for five consecutive days, the highest concentration of MDA in fried products was obtained in the last days of the cycle (4th day). The acid value in the fried oil samples ranges from 0 - 1 mg, the peroxide index from 2 - 5.78 meq/kg, and the concentration of MDA ranges from 0.22 - 2.98 µmol/L. A combination of results of the degree of fat oxidation in fried meat and fish ball products and frying oils indicates that the sellers reused the oils and tended to renew them every 3 - 4 days.

Green supplier selection for manufacturing organization using a hybrid MCDM approach
Authors: Agarwal Ankur , Pant Arati , Agarwal Monica
Published: June 2023

In today’s competitive era business demands cost-effectiveness, logistic efficiency, quality products, after sale services, and environmentally responsible production activities. Sustainable development is need of the hour. Government as well as private agencies and business organisations are emphasising on its implementation in all business activities. Green production, green logistics and green waste management are the three major green business activities. A supplier, who has sensitivity towards the environment along with economic factors is the real asset of a green business chain and is termed as green supplier. In this study. we are concerned with “green supplier selection” by ranking the available green suppliers. The ranking of green supplier selection is considered to be a multi-criteria optimisation problem, which is more popularly known as a multi-criteria decision-making (MCDM) problem. We have applied five different MCDM techniques to rank the green suppliers for the manufacturing organisation in the Delhi-NCR region and proposed an integrated approach of MCDM for assessment and selection of the green supplier. The study is novel in nature as it suggests the ranking of green suppliers by identifying the preferential suppliers to carry forward a green business chain.

Published: June 2023

This article analyzes the relationship of philosophy and theology to the phenomenon of thinking–logic culture. Religions, as you know, can be divided on different grounds. Religion is, of course, not only a form of social consciousness, as, for example, he taught the official world communication. Religion is a rather complex sphere of culture. The article is based on some of the paradigms of religions: firstly, it is the recognition or non-recognition of the existence of God (gods). In this case, religions are divided into non-theistic (recognizing the existence of God or gods) and non-theistic (denying the existence of God or gods. The second type includes, for example, Buddhism. The second basis for distinguishing religions is the number of postulated and revered gods. As a rule, either many gods are postulated (this is polytheism) or one god (this is monotheism). Finally, the third foundation is the status of religion in humanity, the degree of its prevalence, and the number of its adherents. In particular, philosophy is, as is well known, a critical reflection on ideological and world-related problems. The authors argue that the formation of logic in the period of the medieval Muslim East is due to the complex process of the formation of philosophy, humanities, and medieval science in general, in the process of a complex dispute with theology.

Published: June 2023

The essence of a person is determined on the basis of the unity of social and biological. The relationship between man and society has become one of the main problems of science and philosophy. This form of relationship has changed both with the evolution of the natural environment and with the development of man and society. Modern globalization and intensive scientific and technological progress give a new character to the relations between man and society. At all times there has been a society that fully introduced a person into life, filling his behavior with social content. A number of qualities inherent in a person are the result of a person's assimilation of cultural values in the society in which he lives. Philosophical understanding of the relationship between society and man, its discovery in a new way has become an urgent problem for the progressive development of society, the future of mankind. The article reveals the social essence of a person, analyzing socio-ethical, anthropological ideas about the relationship between a person and society. Socialization and its mechanisms and approaches are specified. The role of society and social relations in the formation of an individual personality strategy is studied.
Smart Learning using IOT Technology
Authors: Shubham Sambhaji Kadam
Published: June 2023

Information and communication technologies (ICT) and the ongoing integration of new technologies into institutional learning have led to the development of smart education, which is now a common component in education. The goal of the smart classroom is to help students learn new skills, adapt to new situations, and use technology in a way that results in improved learning outcomes and big data. A new technology known as the internet of things (IoT) enables devices with sensors, actuators, and processors to connect with one another and carry out useful tasks. Designing under these circumstances might be challenging because of the quick evolution of technology. IoT application design is a difficult problem. The current standardisation efforts frequently duplicate IoT development. The reference architecture offers a remedy for superfluous design tasks in smart education. This chapter's goal is to examine the prerequisites and architectural frameworks for smart education. A scalable and adaptable IoT architecture for smart education (IoTASE) is being presented

Published: June 2023

La pandemia Covid-19 supuso un fuerte impulso al teletrabajo y la formación virtual. El alumnado y el personal empleado tuvieron que desarrollar nuevas competencias para adaptarse al formato on-line. Ante esta situación, si bien han proliferado los estudios sobre los efectos de la pandemia tanto en el ámbito laboral como en el educativo, es poca la literatura acerca de su impacto en las prácticas curriculares. El presente estudio aborda el análisis, desde la perspectiva empresarial, de las competencias requeridas para la realización de teleprácticas eficaces. Se elaboró una encuesta exploratoria para conocer la opinión de las empresas que habían acogido estudiantes en prácticas on-line acerca de su intención de mantener esta modalidad en el futuro y de las competencias que más valoraban en su desempeño. A partir de esta, se ha realizado un análisis descriptivo de los resultados obtenidos, seguido de una prueba de proporciones Chi-Cuadrado. A continuación, se ha desarrollado un análisis factorial exploratorio y ejecutado un análisis de componentes principales (PCA). El objetivo era detectar relaciones de interdependencia entre las distintas competencias y, así, sintetizar la información mediante la creación de factores que las agrupan. Asimismo, se ha realizado un análisis cualitativo del contenido de la pregunta abierta sobre otras competencias requeridas. Los resultados del estudio introducen la singularidad competencial de las teleprácticas y permiten vislumbrar la necesidad de seguir investigando para crear un modelo eficaz que mejore la empleabilidad de los futuros egresados.
¿Fomenta la educación universitaria el aprendizaje de competencias emprendedoras sociales? Percepción del alumnado de una universidad pública española
Authors: López Requena Estefanía , Palomares-Montero Davinia
Published: June 2023

El auge del emprendimiento social es un hecho evidente, tanto en su reconocimiento dentro de la comunidad científica, como en el creciente número de empresas sociales, en el aumento de apoyo gubernamental, en su reconocimiento legal, entre otros. Especialmente en contextos de crisis económicas, los gobiernos no dudan en promocionarlo como posible vía de crecimiento económico y social. Una de las posibles estrategias para su impulso es a través de la educación. Concretamente, este artículo muestra los resultados obtenidos en una investigación desarrollada en una universidad pública española, la Universitat de València, en relación al estudio del fomento y/o enseñanza de las competencias emprendedoras sociales. En este caso, se muestra el procedimiento seguido en el diseño, validación e implementación del instrumento de recogida de información diseñado ad hoc: el cuestionario. En cuanto a los resultados principales del estudio se puede recoger que el alumnado de último curso de grado universitario en la Universitat de València opina que la cantidad de formación percibida sobre indicadores que mejor definen al emprendimiento social es escasa; sin embargo, consideran que esta formación es importante y necesaria para su futuro; además, también expresan una escasa intencionalidad emprendedora, siendo esta una alternativa profesional secundaria.
Review of socio-residential vulnerability identification methodologies. Application to the cities of Bilbao and Barcelona
Authors: García Almirall Pilar , Cornadó Còssima , Piasek Gonzalo , Vima Grau Sara
Published: June 2023

This article presents the most widely used methodologies to measure, analyse and assess the state of the building stock and the life conditions of people living in vulnerable neighbourhoods, in an attempt to identify limitations and opportunities within the design of more suitable instruments that will allow us to identify residential communities in a vulnerable situation, residential exclusion or at difficulty to access rehabilitation subsidies or allowances. The methodology adopted is based on the obtention of a first vulnerability index constructed from quantitative data that allows us to focus on the most vulnerable areas of the cities under study. Later, it is complemented with qualitative analysis, interviews to technical officers, entities’ representatives, and site visits and observations. The main obtained results consist of different methodological approaches and analytic and geospatial measurements of the residential vulnerability in the cities of Barcelona and Bilbao: from quantitative large-scale multicriterial analysis, geospatial analysis on specific aspects, to small-scale qualitative study cases, fieldwork and interviews to different actors. In conclusion, by applying those different methodologies in the same specific areas, we were able to determine how data disaggregation and specificity in relation to urban and building form and location provide relevant differential results that help to qualify certain patterns that can be detected but not explained by quantitative larger-scale integrative analysis. Besides, the qualitative information provided by key local agents of different networks was crucial to explain and understand the nature of geographical and time-changing patterns of residential vulnerability.

Authors:   , Suman Akanksha , Sinha Sangeeta , Singh Sunita
Published: June 2023

Background This study examines the concept that elevated homocysteine levels are associated with sudden infant death syndrome. The study aimed to determine whether elevated serum homocysteine levels were related with an increased risk of iatrogenic stillbirths. Method In this retrospective case-control study, 100 women who had stillbirths for unknown reasons and 100 who had normal pregnancies served as cases and controls, respectively. The serum homocysteine levels were evaluated using enzyme assays, and other pertinent clinical and demographic information was also gathered. Result Significantly differing homocysteine levels were found between the case group (mean ± standard deviation: 12.5 ±2.1 units) and the control group (mean± standard deviation: 8.3± 1.5 units; p0.001). After adjusting for potential confounding factors Conclusion The results suggest that elevated serum homocysteine levels may be a biomarker for the unknown risk of stillbirth in women. Further research is required into potential treatments and prevention strategies for hyperhomocysteinemia-related pregnancy complications. This study supports the theory that elevated homocysteine levels induce sudden infant death syndrome. Significant therapeutic implications result from these findings, as systematic homocysteine monitoring throughout pregnancy may help identify high-risk patients and implement appropriate therapies to reduce stillbirths. Recommendation There is a need for additional research to validate these findings and investigate methods to reduce maternal homocysteine levels.uch as maternal age, smoking status, and gestational age, logistic regression analysis revealed a important association between elevated serum homocysteine levels and unexplained stillbirths (odds ratio: 2.90, 95% confidence interval: 1.70-4

Discussions and Developments During the Preparation of The Turkish Civil Laws Accepted in 1926, 2001
Authors: DOYRAN Muhabbet
Published: June 2023

Mustafa Kemal Pasha, the founder of the Republic of Turkey, which aims to create a modern state and society, and Mahmut Esat Bozkurt, the Minister of Justice. They made a legal revolution to implement the “Law of Persons”, “Family Law,” “Law of Inheritance”, “Law of Property” and “Law of Obligations”. For this purpose, the “Civil Law Commission” was established among various law commissions established by the Ministry of Justice. The commission, which started its work for the “Turkish Law Medina” (TKM), decided to take the civil law of a country in Western Europe as it is. In line with this decision, the “Swiss Civil Code” was taken as a whole with some changes and translated by the scientific committee. On February 17, 1926, the articles of TKM were accepted by voting one by one in the Turkish Grand National Assembly (TBMM). As a complement to this law, the Swiss Code of Obligations was also fully adopted, adopted and voted in the Grand National Assembly of Turkey on April 22, 1926, and both laws entered into force on October 4, 1926. Switzerland has made innovations in the “Civil Code” (MK) in accordance with its social needs and structure, and has created a number of new institutions. In Turkish society, which has a different cultural and social structure, it has been decided to implement a new CC instead of going through revision due to its unique characteristics and needs. Harmonization with the acquis during the candidacy negotiations with the European Union (EU) has been an important factor in taking this decision. The new CC studies were carried out on a very wide platform, and finally the draft was accepted in the Grand National Assembly of Turkey on November 2, 2001, and entered into force on January 1, 2002.

Published: June 2023

Wind power is one of the thriving renewable energy technologies lately in the world. Therefore, the assessment of wind speed data is imperative for a specific site. This study focused on geostatistical modeling of wind speed distribution in Uganda. Wind speed data from 1981 to 2019, recorded at a height of 10 m above mean sea level was captured from NASA POWER Data Access Viewer and analyzed. The study area consisted of 35 stations evenly distributed over the country. Probabilistic assessment was performed using Minitab® statistical software to determine the best-fitting probability distribution function to the data sets. Experimental semi-variograms were calculated using exceedance probability data sets of 20%, 50%, 80%, and 95% obtained from probabilistic analysis. The theoretical models were then fitted to the experimental semi-variograms. Jack-knifing cross-validation approach was employed to assess the performance and validity of the theoretical semi-variogram models and their parameters. Kriging maps for the wind speed of pre-defined probabilities were then generated using JeoStat geostatistical software and Surfers 13®. Of the different theoretical semi-variogram models tested, the spherical model showed the best fit to all experimental semi-variograms. Cross-validation proved that the theoretical models obtained were in good agreement with the experimental data used. The kriging maps revealed that areas around Lake Victoria and Mt. Elgon experience higher wind speeds compared to other parts. Therefore, Kriging maps can be used to assess spatial distribution and magnitude of wind speed as well as the representativeness of geographical locations of observation stations.

The mixture of cis and trans-[RuCl2(dppe)2] (dppe: 1,2-bis-(diphenylphosphino)ethane) was prepared and the interaction with CT-DNA was evaluated by several methods, including UV-vis DNA spectroscopic titration, viscosity, and electrochemical studies. Investigation suggests that [RuCl2(dppe)2] interacts moderately with CT-DNA. Interestingly, the cis- and trans-isomers interact differently with DNA, as proved by the square-wave voltammetry studies. Finally, the crystal structure of trans-[RuCl2(dppe)2]Cl was obtained from an electrochemical solution and studied in detail, which presents a distorted octahedral geometry and interatomic parameters different from those found in the trans-[RuCl2(dppe)2] complex. Crystal data for C52H48Cl4P4Ru: triclinic, space group P-1 (no. 2), a = 9.240(3) Å, b = 10.9290(18) Å, c = 11.993(3) Å, α = 78.707(11)°, β = 86.712(13)°, γ = 82.598(13)°, V = 1177.1(5) Å3, Z = 1, T = 293(2) K, μ(MoKα) = 0.732 mm-1, Dcalc = 1.467 g/cm3, 8434 reflections measured (6.934° ≤ 2Θ ≤ 51.986°), 4607 unique (Rint = 0.0973, Rsigma = 0.1171) which were used in all calculations. The final R1 was 0.0537 (I > 2σ(I)) and wR2 was 0.1347 (all data).

Authors: Ebrahimzadeh Mohammad Ali , Alizadeh Seyedeh Roya , Hashemi Zahra
Published: June 2023

The green technique is a unique way to produce functional nanoparticles. We examined the green synthesis of Ag nanoparticles (O-AgNPs) by the extract of Oxalis corniculata. Green-synthesized O-AgNPs were accomplished by monitoring critical factors such as concentration, pH, reaction time, and temperature. Several analytical techniques, including scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction analysis, and UV-Vis spectroscopy, were applied to characterize O-AgNPs. The SEM analysis showed O-AgNPs with a spherical shape and an average size of 33.57 nm. The XRD pattern indicated the face-centered cubic (fcc) structure of the prepared O-AgNPs. The anticancer activity of the synthesized O-AgNPs was investigated in MCF-7 (breast) and AGS (gastric) cell lines, indicating high anticancer effects against selected cell lines. The growth of all selected bacteria containing Gram+ and Gram- was inhibited by O-AgNPs. O-AgNPs showed greater inhibition in comparison to conventional antibiotics. As a result, our green synthesized AgNPs using plant extracts exhibited anticancer and antibacterial activities.

Published: June 2023

The objective of the present study was to examine the chemical compositions of Salvia coccinea oleoresins prepared in methanol and petroleum ether. GC-MS analysis of Salvia coccinea methanolic oleoresin (SCMO) and Salvia coccinea ether oleoresin (SCEO) resulted in the identification of 15 and 12 constituents, comprising 84.7 and 81.2% of the total composition, respectively. Both SCMO and SCEO varied in their chemical composition in terms of quantity, namely, oleic acid (22.3-25.9%), palmitic acid (8.9-8.4%), stigmasta-3,5-dien-7-one (3.4-11.8%), stigmasterol acetate (3.5-5.3%), neophytadiene (4.8-1.7%), phytol (1.6-7.8%) and phthalic acid (2.1-3.1%). In addition to the qualitative differences between SCMO and SCEO concomitantly, both oleoresins were examined for their pesticidal activities. Oleoresins demonstrated significant nematicidal activity against Meloidogyne incognita, insecticidal activity against Lipaphis erysimi, antifungal activity against Curvularia lunata, and antibacterial activity against Staphylococcus aureus. For nematicidal activity, SCMO and SCEO exhibited a high mortality of 65.66±1.69 and 54.33±1.24 and egg hatching inhibition of 26.33±1.20and 33.33±1.24 at 200 μg/mL. Similarly, SCMO and SCEO exhibited excellent insecticidal activity with 94.87±1.44 % and 86.75±1.85 %   mortality at 1000 μg/mL. However, both oleoresins exhibited moderate antifungal and antibacterial activities compared to standards. Due to the quantitative difference in chemical composition and the presence of several phytoconstituents that were absent in SCEO, SCMO displayed stronger pesticidal effects than SCEO. To estimate the binding energy and structure-activity relationships between chemical constituents and pesticidal activities, in silico molecular docking and ADME/Tox studies have also been performed using a web-based online tool. On the basis of the present study, it is inferred that the herb Salvia coccinea might be a good source of phytochemicals and can be used for the development of herbal-based pesticides/formulations after proper clinical trials.

Published: June 2023

In this study, gold nanoparticles were synthesized using the fruit extract of Sambucus ebulus (S. ebulus) as a reducing, capping, and stabilizing agent. Biogenic synthesis of gold nanoparticles (Au nanoparticles) was accomplished using S. ebulus fruit extract in the presence of hydrogen tetrachloroaurate(III) trihydrate at a temperature of 65 °C and the solution stirred at 400 rpm. The characterization of the synthesized nanoparticles (SE-AuNPs) was performed using different analytical methods, such as scanning electron microscopy (FE-SEM), energy dispersion X-ray spectroscopy (EDS), Fourier transform infrared (FT-IR), X-ray diffraction analysis (XRD), and UV-vis spectroscopy. A strong absorption peak at 565 nm confirmed the formation of the gold nanoparticle. On the basis of the electron microscopy results, AuNPs were mostly spherical with an average size of 116.2 nm. The cubic crystalline structure of the prepared nanoparticles was confirmed using the XRD pattern and the average crystallite size was obtained at 28.471 nm. FT-IR analysis confirmed the presence of functional groups in the plant extract for the synthesis of nanoparticles. SE-AuNPs showed good antibacterial activity against Gram-positive and Gram-negative bacteria tested and exhibited potent antileishmanial activity. Furthermore, SE-AuNPs showed excellent antioxidant activity that inhibited DPPH radicals with an IC50 value of 21.976 µg/mL. The prepared AuNPs acted to degrade methyl orange (MO), which was performed in sodium borohydride and visible light.
QSAR study of benzofuran and indole derivatives to predict new compounds as histone lysine methyl transferase inhibitors
Authors: Sarkar Kaushik , Ghosh Sraboni , Das Rajesh Kumar
Published: June 2023

Initiation and progression of several diseases by post-translational histone modifications are considered a worldwide problem. Enhancer of Zeste Homologue 2 (EZH2), which belongs to the histone-lysine N-methyl transferase (HKMT) family, has been emphasised as a promising target for cancer therapy. It is a major challenge for the scientific community to find novel approaches to treating this disease. In this study, a series of 51 derivatives of the benzofuran and indole families, previously experimentally evaluated against HKMT, was used to develop the best model with promising anticancer activity. The multiple linear regression (MLR) method, implemented in QSARINS software, was used with a genetic algorithm for variable selection. According to QSARINS, the model with two descriptors (minHBint4 and Wlambdal.unity) was found to be the best and its parameters fit well, and its validation was well established. The applicability domain was also validated for this model. Furthermore, its robustness (R2 = 0.9328), stability (Q2LOO = 0.9212, Q2LMO = 0.9187), and good predictive power (R2ext = 0.929) were also verified. Hence, this model was assumed to have predictive HKMT anticancer activity for designing active compounds. Molecular docking was also performed to identify binding interactions, and new molecules with better predicted biological activity (pIC50) were designed. The binding energy of the three designed compounds demonstrated higher binding activity at the target receptor, followed by complex stability, determined by a 100 ns molecular dynamics simulation and binding free energy calculation. Density functional theory (DFT) and pharmacokinetic analyses also confirmed their drug-like properties. Finally, it can be declared that the proposed tools allow rapid and economical identification of potential anti-HKMT drugs (anticancer drugs) for further development.

Current water management does not fully account for potential crisis situations when dealing with drinking water. It is important to focus on an efficient and at the same time economic approach to water management, including consideration of the ecological aspect. One way is to focus on the use of alternative sources of water. The possibilities of purified wastewater or captured rainwater indicate a certain direction. Current technical possibilities and scientific knowledge offer many opportunities. The priority is to find and increase the way to limit the use of drinking water for economic activities. The more intensive use of alternative water sources is still in the background and neglected. This article provides information on this issue and encourages deeper ecological and economic reflexion.

Tujuan penelitian ini adalah mengkaji interaksi default-intervionist (DI) siswa sekolah dasar. Interaksi DI adalah interaksi berpikir yang melibatkan sistem 1 dan sistem 2. Metode penelitian ini menggunakan pendekatan kualitatif dengan jenis studi kasus. Instrumen penelitian ini terdiri dari peneliti sebagai instrumen utama, rubrik indikator interaksi DI, masalah geometri, pedoman wawancara semi-terstruktur, catatan peneliti, dan alat rekam video. Hasil penelitian ini menunjukkan bahwa ada tiga jenis interaksi DI. Jenis 1 melibatkan proses otomatis, proses subjektif-empiris, dan proses menyadari. jenis 2 melibatkan proses otomatis dan proses menyadari. Jenis 3 melibatkan proses otomatis, proses tanpa menyadari dan proses menyadari. Pada interaksi DI jenis 1 proses otomatis terjadi ketika subjek menggambar sketsa segitiga siku-siku tanpa mengukur secara cermat, proses subjektif-empiris terjadi ketika subjek menganggap telah mengahsilkan sudut siku-siku segitiga siku-siku melalui kesan visual, dan proses menyadari terjadi ketika subjek mencermati gambar sketsa segitiga siku-siku dan menghasilkan anggapan bahwa gambar sketsa yang dihasilkan memenuhi sebagai gambar segitiga siku-siku. Pada interaksi DI jenis 2, proses otomatis terjadi ketika subjek memilih bilangan bulat sebagai ukuran sisi dan proses menyadari terjadi ketika subjek memutuskan untuk menghitung bilangan yang dipilih melalui cara bersusun karena tidak hafal hasil operasinya. Pada interaksi DI jenis 3, proses tanpa menyadari dan proses otomatis terjadi ketika subjek menggambar sketsa segitiga siku-siku tanpa mencermati ukurannya dan proses menyadari terjadi ketika subjek mengitung persegi satuan di daerah dalam gambar sketsa segitiga siku-siku yang dihasilkan

Pentingnya penelitian ini untuk dibahas karena menyajikan permasalahan yang aktual, problematik, dan bersangkutan dengan konsep matematika yang lain. Tujuan penelitian ini adalah untuk menemukan akar-akar permasalahan atau penyebab dari kesalahan siswa dalam memahami konsep perkalian sebagai penjumlahan berulang beserta solusinya. Metode penelitian yang digunakan adalah metode Systematic Literature Review (SLR). Penelitian dianalisis menggunakan diagram fishbone yang terdiri dari aspek machine, man, method, material, measurement, dan environment. Hasil penelitian ini menunjukkan bahwa penyebab dari kesalahan siswa dalam memahami konsep perkalian sebagai penjumlahan berulang adalah tidak menggunakan alat peraga dalam menjelaskan konsep, jika menggunakan alat peraga biasanya jumlahnya minimum dan sulit diakses banyak siswa, kesalahan guru dalam menjelaskan konsep, siswa tidak bisa membedakan pengali dengan bilangan yang dikali, metode pembelajaran yang digunakan berfokus pada guru, konsep diajarkan secara abstrak bukan konkret, penilaian orang sekitar yang salah, kesalahan dibiarkan secara terus menerus, dan penggunaan sumber bacaan atau pengetahuan yang salah.

Abstract. The vertical distribution of black carbon (BC), as well as its
mixing state, is of great concern due to BC's strong regional climatic and
environmental effects. In this study, vertical measurements were conducted
through a moveable container based on a meteorological tower in the Beijing urban area during June and July. A total of 112 vertical profiles (0–240 m),
including the concentrations of BC, O3, NOx and the optical
properties of aerosols, were obtained. Based on BC concentration, the
vertical profiles could be classified into four categories: uniform, gradual decrease, sharp decrease and sudden increase. The uniform type indicates
strong vertical mixing with similar pollutant concentrations along the
vertical direction. The gradual and sharp decrease types indicate stable
vertical conditions with higher pollutant concentrations on the ground and
lower concentrations at higher altitudes. Due to the strong radiation in
summer, the vertical profiles exhibited a clear diurnal variation in which
∼ 80 % of profiles were uniform during the daytime and
∼ 40 %–90 % of profiles were of the gradual and sharp decrease types
at night. O3 is an exception, and its concentration generally increases
with height, even under strong vertical mixing conditions. The size
distribution of the BC core varied slightly along the vertical direction, and
the coating thickness, denoted by the diameter ratio between the
BC-containing particle and BC core (Dp/Dc), of BC increased with
height under stable conditions. Although the coating thickness could
increase the absorption ability with an average absorption enhancement of
1.25 at 23:00 LT (local time: UTC+8), the vertical difference of Dp/Dc (2 %) was much
lower than that of BC concentration (∼ 35 %). The vertical
variation in absorption ability was mainly caused by the variation in BC
concentration. In addition, O3 and Dp/Dc occasionally
increased during 06:00–08:00 but remained stable during 08:00–10:00. Vertical
mixing and transportation from upper heights, such as the residual layer,
could significantly influence the pollutant properties on the surface during
early mornings. This study exhibits a continuous vertical picture of BC and
its mixing state in urban areas, which would be helpful for understanding
BC's regional environmental effect.

Abstract. Pre-launch simulated satellite data are useful to develop retrieval algorithms and to facilitate the rapid release of retrieval products after launch. Here we introduce the Japanese Aerospace Exploration Agency's (JAXA) EarthCARE synthetic data based on simulations using a 3.5 km
horizontal-mesh global storm-resolving model. Global aerosol transport
simulation results are added for aerosol retrieval developers. Synthetic
data were produced corresponding to the four EarthCARE instrument sensors,
namely a 94 GHz cloud-profiling radar (CPR), a 355 nm atmospheric lidar
(ATLID), a seven-channel multispectral imager (MSI), and a broadband
radiometer (BBR). JAXA EarthCARE synthetic data include a standard product
with data for two orbits and a research product with shorter frames and more
detailed instrument settings. In the research products, random errors in the
CPR are considered based on the observation window, and noise in ATLID
signals are added using a noise simulator. We consider the spectral
misalignment effect of the visible and near-infrared MSI channels based on
response functions depending on the angle from the nadir. We introduce plans
for updating the JAXA EarthCARE synthetic data using large eddy simulation
model data and the implementation of a three-dimensional radiation model.
The JAXA EarthCARE synthetic data are available publicly.
