Galling-free fine blanking of titanium plates by carbon-supersaturated tool steel punch
Authors: AIZAWA T.
Published: April 2023

Abstract. The carbon supersaturated tool steel and high-speed steel punches were utilized to demonstrate that the titanium work materials were forged in high reduction of thickness and fine-blanked without adhesion of their fragments and deposition of their oxide debris particle. This galling free forging and fine blanking came from the in situ formation of the free carbon tribofilm only on the highly stressed interfaces between the punch/die and the titanium work. Under this in situ solid lubrication, the low frictional state was sustained to induce less bulging deformation of work during the forging process. The fine blanking of titanium plates advanced without adhesive wear and fractured regions on their sheared surface. The long life of tools was certified even in fine blanking of titanium and titanium alloy plates.

Published: April 2023

In the 21st century of technology and the digital era, the integration of science, technology, engineering and mathematics in educational, political and economical is becoming an integral part. The implementation of STEM in the learning context should be followed by the readiness of teacher capability and supported by STEM-based teaching materials. This paper implements Design and Development Research (DDR) which followed the six stages to produce a STEM-based module for 7th graders, particularly on earth's structure and its dynamic topic. The developed STEM-based module follows the basic national competence for secondary level, module criteria, criteria of great STEM learning materials, STEM literacy practices and Engineering Design Process from NGSS and NRC (2010), OECD (2016), NAEP (2014) and National Kurikulum 2013. The questionnaire is delivered to experts, teachers and students to test the validity and readability of the STEM-based module. Moreover, it is also implemented as a learning module in one class of 7th graders in SMP Negeri 03 Soreang, which consists of 32 students. The results show that STEM-based module is valid to be used by high school students. Moreover, the readability score reaches 88.39%, while the response towards layout, content and utility aspects is 94.44% means that it had a minor revision.

Published: April 2023

This study aimed to describe the improvement of students' science process skills (SPS) after the implementation of home-based experiment activities on photosynthesis material. This research was carried out at one of the State Junior High Schools in Garut. The sample was 26 students for the experimental classes and 25 students for the control class. The research design was Pre-Posttest Control Group Design. The sample selection technique used the convenience sampling technique. The success of the learning method/model implemented was assessed through value analysis before (pretest) and after (posttest) given treatment in the experimental and control groups. The N-Gain value of the experimental group was 0.678, while the N-Gain value of the control group was 0.52. This indicated that the N-gain value of the experimental group was higher than the control group. But, the statistical analysis using post-test scores showed that there was no significant difference between the experimental group and the control group in the students’ SPS. So, the implementation of home-based experiments and ordinary practicum in the learning process has the same effect on students’ SPS results. Therefore, home-based experiments should be an option for teachers in science learning because, even though the learning process is online, the practicum is the identity, and support of science learning should not be eliminated.

Published: April 2023

Online learning during the pandemic has an impact on the student’s learning behavior. It altered the way students learn and manage their time. This research aims to explore students’ self-regulated learning in undergraduate students of the department of Biology Education based on gender and disciplinary differences. Research participant was distributed into female and male students. It was also distributed into two different study programs: biology and biology education. 24 questions were administered online to 124 students. The instrument consists of six sub scales, 1) goal setting, 2) environment structuring, 3) task strategies, 4) time management, 5) help seeking, and 6) self-evaluation. The relationship between students’ self-regulated learning toward gender and the relationship between students’ self-regulated learning toward study program were analyzed using independent sample T test. In addition, correlation analysis was also conducted to find the correlation between students’ self-regulated learning and students learning achievement. The results showed that there was no significant relationship between male and female students towards self-regulated learning (p = 0,665) and study programs (p = 0,008). The research results also show that there is a correlation (r = 0,0270) between student achievement and self-regulated learning.
Fault systems in multiply deformed regions of Eurasia
Authors: Burtman V , Kolodyazhnyi S
Published: April 2023

We have studied the orogenic fragile deformation of the upper Earth's crust of several areas of the Eurasian continent, where deformations have occurred many times -- in the Tian Shan and Altai-Sayan regions of the Central Asian Paleozoic Fold Belt and in the Baltic region in the Fennoscandian Shield (East European Platform). Our processing of data on the trends of more than 4000 faults allows us to identify fault systems and relationships among these fault systems. Changes in the intensity and kinematics of the activity of fault systems in different epochs of deformation of regions are revealed. In the Tien Shan and Altai-Sayan regions, fault movements occurred during Early Paleozoic, Late Paleozoic and Late Cenozoic orogenies. No new fault systems appeared in the Late Cenozoic deformation in the Tien Shan, where only movement along Paleozoic faults that were suitably oriented occurred. In the Altai-Sayan region, we identify the Late Paleozoic associations of fault systems that activated in the recent epoch and the association of fault systems created in the Late Cenozoic. The Fennoscandian Shield shows different fault kinematics in four Early Proterozoic deformational periods. Our method of analysis of associations of fault systems contributes to a~systematization of data on multi-stage deformation in the upper crust of these regions.

Authors: Jiyang Qiu
Published: April 2023

Image is a very important component in poetry which is the combination of object things and subjective feelings. Proper translation of images secures smooth communication between the readers and the poets. The author aims to apply cognitive linguistics to analyze the cognitive process of transferring imagery of “the moon” in Chinese Classical poetry. On the basis of the close connections between the translator’s internal cognitive mechanism and the comprehension and reproduction process of imagery and ideorealm, the possibility to reproduce the original imagery and ideorealm in the translations is analyzed to facilitate cross-cultural communication.

Published: April 2023

Given that probiotics always have host-homologous and strain-specific effects on the hosts, lactic acid bacteria extracted and identified from porcine specimens can be potentially developed as probiotics for pig production. We aimed to identify lactic acid bacteria that are potentially probiotic, have good capacity of inhibiting pathogenic bacteria in intestine and are promising to be used as substitutes for antibiotics in pig production. Potential probiotic strains were extracted from 15 fecal specimens collected from 15 apparently healthy pigs, and were identified via 16S rDNA sequencing. The antimicrobial activity, tolerance to acid and bile salts, Caco-2 cell adhesiveness and susceptibility to antibiotics of the isolates were evaluated in vitro, and oral toxicity of the isolates were evaluated in mice. One Lactiplantibacillus plantarum (BJR2), two Lacticaseibacillus casei (HJD and TH2), one Lacticaseibacillus rhamnosus (MRS1), and two Enterococcus faecium (S-3 and S-4-H) were extracted from healthy pigs and underwent 16S rDNA sequencing identification. L. plantarum BJR2 and L. casei HJD exhibited broad-spectrum and higher antimicrobial activity against indicator enteric pathogens, including Salmonella choleraesuis CVCC 2139, Escherichia coli (O147:K89) CVCC 199, Escherichia coli (O141:K99) CVCC 223 and Escherichia coli (O139) CVCC 1496, among 6 tested strains. In addition, both L. plantarum BJR2 and L. casei HJD exhibited good tolerance to low pH (pH 2.5 and pH 3.5) and 0.30% bile salts, had relatively strong Caco-2 adhesiveness and carried no transferable resistant genes against antibiotics encoded by plasmid. In safety trials, these two isolates had no α or β-hemolysis activity, and were proved safe through oral toxicity tests in mice. It is concluded that L. plantarum BJR2 and L. casei HJD are potential probiotic candidate strains and their probiotic effects need to be further studied in pigs.
VR Based Remote Campus Tour

Published: April 2023

Abstract: We recommend a system called "Virtual Tour of College Infrastructure" that gives a virtual college tour to visitors, such as students, parents, and guests. They may be interested in learning about the facilities and infrastructure offered by the college. For this, students must really travel to the college campus, which will take a lot of their time and effort and cost money for those who live far away. The suggested solution offers a virtual perspective of the infrastructure at the college in order to address this problem. This enables visitors access a certain department or lab from a distance. Additionally, it can be displayed at the College's main gate to assist visitors in finding a certain student, member of staff, or lab by outlining the precise route through the "Search" module. Virtual reality is essentially how this technology operates. Combining two or more photos to create an image panorama is the procedure. The method of producing an image panorama from a collection of photos with overlapped fields is known as image stitching. The process of stitching together photographs is difficult because of issues including noise-corrupted images, indexing a lot of images, high image resolution, parallax, and scene motion. Another difficulty is getting rid of seams that are noticeable. This work applied a feature-based automatic image stitching approach to obtain a broad seamless panorama.

As ideias filosóficas de Eduardo Ferreira França (1809-1857)
Authors: Margutti Paulo
Published: April 2023

O presente livro sobre Eduardo Ferreira França marca uma alteração no desenvolvimento de nossas pesquisas a respeito da filosofia brasileira do s. XIX. Com efeito, depois de redigir o primeiro e o segundo volumes de nossa História da filosofia do Brasil, passamos a trabalhar no terceiro volume. No decorrer deste processo, fomos constatando gradativamente que não seria possível manter o mesmo esquema de tratamento exaustivo dos diversos autores nos volumes anteriores. Estávamos diante de pensadores mais importantes, em maior número e com obras mais extensas e significativas, o que transformou as pesquisas sobre cada um deles em pequenos livros. Acontece que a reunião destes pequenos livros para compor o terceiro volume simplesmente produziria uma obra excessivamente alentada, coisa que consideramos desaconselhável. Ora, a exegese detalhada das doutrinas de cada um dos autores envolvidos constitui condição necessária para a elaboração da parte final do terceiro volume, permitindo não só a discussão com os diversos historiadores da filosofia brasileira, mas também a formulação das nossas conclusões na parte final, que faz um apanhado geral da época no domínio filosófico.

Virtual Production and the potential impact on regional filmmaking
Authors: Fair James
Published: April 2023

Virtual Production (VP) has seen enormous growth in the last few years. The technology enables filmmakers to project locations onto a giant LED wall backdrop in a studio space, providing a photorealistic setting at the click of a button. Exciting though these developments are for the industry, our governments need to explore and understand what the trend away from traditional filmmaking may mean. There could be some hidden consequences that impact upon existing policy objectives. This paper focuses specifically upon the potential challenges that regional filmmaking may face as a result of VP; including a loss of production revenue in the local economy, possible skills migration and a threat to screen tourism. The paper argues that interventionist policy making, similar to successful tax relief schemes that have invigorated the UK cultural industries in recent years, could help steer the new technology in directions that help meet wider policy agendas, rather than usurp them.

Published: April 2023

Este trabalho se insere numa linha de publicações que estabelecem contribuições ao ensino da Física Moderna, especialmente à Física Nuclear em nível médio de ensino. Nesse contexto, muitas propostas apresentam fenômenos reais por meio de simulações computacionais sem atividade experimental. Isso se deve, por exemplo, devido ao elevado custo de um detector de radiação e a regulamentação burocrática para o uso de uma fonte radioativa no Brasil, exigindo cuidados especiais de manuseio e armazenagem dela. Assim, o presente estudo objetivou apresentar um protótipo de um detector de faíscas de baixo custo via Arduino, com a finalidade educacional de favorecer o entendimento dos princípios de funcionamentos dos medidores tradicionais de radioatividade quando simula experimentalmente a coleta de dados sem o emprego de fontes radioativas. Para isso, o protótipo foi inicialmente testado, de modo qualitativo e sem quaisquer calibrações para detecção de radiação ionizante (partículas alfa) de uma fonte de Amerício-241. Posteriormente a fonte radioativa foi substituída por uma fonte alternativa que simula uma detecção equivalente, capaz de ser vantajoso e viável à instrução do princípio físico de funcionamento envolvido na contagem de fonte radioativa, atrelando-se uma atividade experimental. Tal alternativa viabiliza o uso do protótipo para aplicação em feiras de ciências e em sala de aula.PALAVRAS-CHAVE: Ensino básico, protótipo detector de faíscas via Arduino, baixo custo, princípio de funcionamento da detecção da radiação ionizante, simulação sem uso de fontes radioativas.

A escola desponta como aliada da Educação Ambiental Crítica (EAC) ao considerar à teia de relações sociais, naturais e culturais em que vive o ser humano. Com o intuito de refletir sobre as vivencias do estágio supervisionado no ensino fundamental pautadas na EAC, delineamos esta pesquisa qualitativa descritiva, utilizando o diário de campo e a narrativa autobiográfica. A autobiografia versou sobre as experiências de um licenciando em Ciências Biológicas, modalidade a distância da Universidade Estadual do Ceará, Universidade Aberta do Brasil (UECE/UAB), oriundas do estágio supervisionado no ensino fundamental II. Durante o estágio, foi possível observar que as aulas eram expositivas e pouco dialógicas, e para contemplar práticas atrativas e dialógicas a regência foi realizada na forma de uma oficina pedagógica intitulada “Mergulho Educativo”, onde constatamos que os alunos reconheciam animais marinhos como tartarugas, baleias e golfinhos, mas desconheciam ou não se interessavam por animais abundantes e importantes no contexto ecológico e econômico local, como os bivalves marinhos. A partir de então, realizamos imersão bibliográfica e elaboramos uma “Cartilha Ilustrada de Bivalves Marinhos”, composta de 24 páginas e com conteúdos relacionados as características biológicas, ecológicas e econômicas dos bivalves marinhos de ocorrência e utilização nas praias do município de Beberibe, cidade onde a escola está situada. O ciclo de observações, registros, leituras e reflexões que culminaram com as ações educativas de execução da oficina “Mergulho Educativo” e elaboração da “Cartilha Ilustrada de Bivalves Marinhos”, evidencia a importância das práticas pedagógicas e matérias didáticos contextualizados e voltados para a formação biológica e socioambiental dos alunos.

Authors: Prom Vireak , Phauk Chinith , Nhep Angkeabos , Vento Sandro
Published: April 2023

Introduction. Kasabach-Merritt phenomenon (KMP) is a rare condition
associated with vascular tumors such as kaposiform hemangioendothelioma
and tufted angioma; it can be life threatening, due to its consumptive
coagulopathy. Thrombocytopenia and hypofibrinogenemia are characteristic
of KMP, and anemia and raised d-dimer levels can also be detected. Here,
we report a 7-month-old Cambodian with the condition. Case Presentation.
The infant was admitted to the National Pediatric Hospital in Phnom Penh
because of a mass on the right side of the neck that had been
progressively enlarging. The patient had severe thrombocytopenia
(8,000/µL), anemia (Hb 7.6g/dL) and reduced fibrinogen level (1.5g/L).
CT scan and histology of the lesion confirmed a diagnosis of hemangioma.
Kasabach-Merritt phenomenon was diagnosed, and the infant was treated
with platelets and fresh frozen plasma infusions, prednisolone
(2mg/kg/day) and propranolol (2.5mg/kg/day). After eight weeks of
therapy, platelets raised to 102,000/µL. The infant developed Cushing’s
syndrome after 6 months of treatment and prednisolone was scaled down to
a maintenance dose of 0.5mg/kg/day. Fibrinogen levels went back to
normal (2.14g/L) after seventeen months of treatment, and the tumor
shrinked significantly. Conclusion. This case report shows that a
combination of prednisolone and propranolol has been effective for KMP
and kaposiform hemangioendothelioma. Timely recognition and treatment of
Kasabach-Merritt phenomenon’s are essenti

Objective: To investigate the safety of purified D. farina and
D. pteronyssinus extract product Novo-Helisen-Depot (NHD) as
subcutaneous immunotherapy (SCIT) in the children with mite allergy.
Methods: We conducted a retrospective study analyzing the
adverse events of the children undergoing subcutaneous immunotherapy
with NHD. Adverse events included local and systemic adverse reactions
(SRs) at the very early and late stage. The correlation of the basic
characteristics, laboratory analysis results and the immediate/late
local reaction (LRs) and systemic adverse reactions (SRs) were analyzed.
Results: 287 patients received at least 15 months of
subcutaneous immunotherapy with NHD were included in the analysis.
Skin-prick testing (SPT) results of D. pteronyssinus was associated with
an increased risk of immediate LRs in build-up phase (OR =1.53, 95% CI:
1.02,2.37) and delayed LRs in maintenance phase (OR =1.58, 95% CI:
1.05,2.46), while SPT results of D. farina was associated with an
increased risk of SRs (OR =3.22, 95% CI: 1.17,10.00) and severe SRs (OR
=7.68, 95% CI: 1.13,109.50). Serum IgE level of D. pteronyssinus was
associated with an increased risk of SRs (OR =1.01, 95% CI: 1.00,1.03).
Patients with both asthma and allergic rhinitis was associated with an
increased risk of SR, and severe SRs ( P<0.05).
Conclusion: NHD as SCIT is safe. The children with higher SPT
level with D. farina or D. pteronyssinus, higher serum IgE level of D.
pteronyssinus, children with both asthma and allergic rhinitis, and the
children with treatment interruption had higher risk of adverse events.
Interpretation of magnetic anomaly profiles using a decomposition in Hilbert transform pairs
Authors: Oliveira Saulo Pomponet , De Souza Jeferson , De Castro Luis Gustavo , Ferreira Francisco José Fonseca
Published: April 2023

ABSTRACT. We propose a simple transformation to aid the interpretation of magnetic anomalies generated by linear structures. The profile of such anomalies perpendicular to the strike can be decomposed into two signals, one symmetric and the other antisymmetric concerning the center of the source. The symmetric component serves as input data to various depth estimation techniques that often assume the anomaly is reduced to the pole. We use the fact that these components form a Hilbert transform pair to transform a skewed anomaly profile into a symmetric one. Unlike in previous works that rely on the decomposition into even and odd functions, the profile does not need to be shifted to the source's center of symmetry or limited to one isolated anomaly. Multiple effective magnetization directions presented by different dikes are modeled by a function representing the different local effective dip angles. We validate the method with synthetic data and ground magnetic survey data from a dike swarm at Ponta Grossa Arch, southern Brazil. We also illustrate the usefulness of reconstructed anomalies for depth estimation methods. The results also show that the method can handle interfering sources with distinct effective magnetization directions.

Published: April 2023

Despite of its economic and scientific significances with mineral resources, the Northern Sea Routes, and climate change, the Arctic Ocean has been a challenge for long-term continuous environmental observations. Since its inception in 2009, the ice-breaker research vessel ARAON has been conducting an annual expedition in the Arctic Ocean for the last 10 years from 2010. All the Arctic expeditions have been carried out mainly in August-September when the sea ice extent shrinks and the thickness becomes relatively thin around the Bering Sea, Chukchi Sea, Beaufort Sea, and high latitudes over the Russia, the US, and Canada. IBRV ARAON can conduct research activities through a variety of research equipment such as on-board meteorological data and surface temperature & salinity monitoring data of seawater. In this study, meteorological observation elements including solar radiation, air temperature, relative humidity, wind speed, and wind direction are presented. In addition, sea surface water temperature and salinity monitoring elements including water temperature, salinity, conductivity, and sound speed are presented.
Hyperspectral Irradiance Data for a Comparison and an Analysis of Optical Satellite Spectral Observation: Based on Seogwipo Forest Flux Tower
Authors: Lee Hongtak , Yeom JongMin
Published: April 2023

Comparison with ground-truth data is essential for developing and applying remote sensing algorithm towards the Earth surface. Unfortunately, major sources of domestic ground-truth data are depending on fieldcampaign with limited period because of insufficient all-time observation facilities within a domestic region. Korea Aerospace Research Institute, KARI, is planning to construct and operate surface observation tower to provide remote sensing infrastructure. This study was conducted as a pilot program of the observation tower construction and targeted to observe surface reflectance. The observation was made for about 21 months from May 2017. Two hyper-spectroradiometers were installed on top of a forest flux tower at Mt. Halla to measure hyperspectral up/down-welling irradiance, and surface reflectance was derived simply from their ratio. The derived surface reflectance was compared to surface reflectance values estimated from LANDSAT8 VNIR images, and the two surface reflectances coincided while showing effectiveness of the derived surface reflectance. The data acquired from this study would be able to provide background information for the expected surface observation tower, as well as actual ground-truth data for remote sensing application upon Mt. Halla area.

The fish community in the Jin Island (Jindo, Jisan, Munnae, Yulri, 1/25,000 scale) was investigated with the data collected through the 3rd National Ecosystem Survey from April to October in 2012. During the period, 25 species belonging to 7 families were collected. There were 11 biological resources subject to the approval of outbound transfer, including Squalidus gracilis majimae, Abbottina rivularis, Aphyocypris chinensis, Hemiculter eigenmanni, Rhodeus ocellatus, Iksookimia hugowolfeldi, Iksookimia koreensis, Trachidermus fasciatus, Monopterus albus, Macropodus ocellatus and Oryzias latipes. The dominant species was Pseudorasbora parva(26.3%), and the subdominant spaecies was Carassius auratus(16.0%).
Background: In Korea, from 1989 National Ecosystem Survey (NES) was conducted by ministry of environment for every 10 years to cover whole south Korea in 1/25,000 scale. The scope of NES including 8 taxa – vegetation, plant, fish, macro invertebrate, insect, birds, amphibian & reptile, mammal and geomorphology. With the results of ecosystem survey we build up species and ecosystem database based on GIS environment. Ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to reduce ecosystem disturbance.
New information: An ecological information platform can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. We designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for various stake-holders. Then, we developed basic functions to analyze ecosystem for each stake-holders (researchers, general public and policy makers). We successfully designed a computing system named EcoBank supporting the functions of Digital Object Identifier (DOI) publish and data quality management.

Authors: Lee Sungjae , Kim Hyun-Cheol
Published: April 2023

The Arctic issue has increased due to global warming. The Arctic is losing the role of cooling because reducing sea ice by warming on the Arctic, which is changing the energy balance on the Earth system. Change of Arctic ocean, atmosphere, and cryosphere influence on an ecosystem of Arctic as well. These changes are monitoring by remote sensing due to the Arctic is difficult for human access, and where is a wide area. However, a low solar altitude on the Arctic limits Ocean Color Algorithms applies to the Arctic because most ocean color algorithms are based on empirical data in the mid-latitude. Continuous data sampling on the Arctic ocean is the best way to improve and develop a suitable ocean color algorithm for the Arctic. This paper aims to report ocean observation data acquired by Ice-Breaker research vessel Araon during the summer Arctic expedition of 2019. Acquired samples are chlorophyll-a, suspended sediment concentration, in-situ measured ocean optical properties. Sampled data showed that there is a significant effect of dissolved organic matter in its inherent optical properties. We use these data for the aims of improving and develop ocean color algorithms in the Arctic.

Published: April 2023

The database was established by conducting field surveys and water quality analysis of 877 water samples based on the national-scale various water sources, including 167 sampling sites from historically well-known hot springs, mineral waters, and spring waters (from August 2017 to June 2020). Spatial analysis using Kriging interpolation was performed to create a distribution map for 14 mineral components. The distribution maps were prepared with 50 m spatial resolution in raster type, and provided by Geo Bigdata Open Platform service of KIGAM. The spatial distribution of each mineral component showed some relationships with geological (lithology and fault) and regional characteristics, and could be used for drinking water and beverage industry (beverages, alcoholic beverages, teas, coffee, etc.) by providing the various information on the occurrence of natural Good-Water. We plan to continuously update information on Good-Water source to increase spatial resolution and secure its representativeness at each location.

The advanced countries, including the United States of America, Japan, the United Kingdom, etc., struggle to secure mineral resources for their development of economy and industry themselves. We, the Republic of Korea need to respond to come up with an effective counterplan for the resource supply and demand accordingly. The Korea Institute of Geological Resources (KIGAM) is a state-designated approval statistic institution and has been building the mineral commodity statistic data of the minerals, officially defined by the mining act of the Korean government since 1986. The statistical data of mineral commodity consist of the sales volume, distribution, and production of mines, and the labor conditions for operation, etc., based on the type of ore and the production of the region, month and mine. KIGAM published the various statistical data containing the production, import, export of the mineral commodity in various forms, including annual and monthly reports and by English. This mineral commodity/mining statistics data can be viewed and downloaded from Korean Statistical Information Services(mici.kigam.re.kr), (www.kosis.kr) by Statistic Korea, Mineral Resources Statistics Portal and also bigdata environment-platform(www.bigdataenvirnment.kr).
