Experimental Study on Dynamic Performance of Tubular Flange Grid-Type Dam under Impact Load
Authors: Wang Xiu-Li , Yao Yong , Wang Sai-Long , Feng Zhu-Jun , Chu Yun-Peng
Published: July 2022

As one of the most dangerous geological hazards in the world, debris flows can destroy trees and structures, break electrical, water, and gas lines, and disrupt bridges and roadways in a short period of time, threatening life and property. In particular, fast-moving large boulders carried by debris-induced destructive impact loading can strike objects without warning. To resist impact loading caused by rocks in debris, this paper proposed an innovative grid-type debris dam (or Sabo dam) design composed of symmetrical cross-sections of steel tubular flange beams and columns. This paper studied the dynamic performance of the tubular flange columns under impact loading by conducting lab tests and numerical simulations. Moreover, the dynamic response of the grid-type debris dam was simulated under various loading conditions. Comparing three different types of columns with similar configurations under the same loading condition, the tubular flange column proposed in this research exhibits better performance in overall strain, displacement, acceleration, and bending conditions. Furthermore, the results also prove that the proposed structure has excellent interoperability and energy absorption capabilities. When increasing the testing impact load, the failure modes of the dam change from dent at the impact point to local buckling and total failure of the structure, which indicates that the structure has superior performance under impact loading.

Authors: Clérigo Fabiana , Ferreira Sandra , Ladeira Carina , Marques-Ramos Ana , Almeida-Silva Marina , Mendes Luís André
Published: July 2022

Emerging contaminants such as nanoplastics (NPs), as well as manufacturing by-products such as plasticizers, have gained global attention and concern due to their limited biodegradability and their potential impact on human health, in particular the effects on respiratory tissue. In parallel, in vitro cell culture techniques are key to the assessment and characterization of toxic effects and cellular mechanisms in different types of tissues and should provide relevant information to understand the hazardous potential of these emergent contaminants. This systematic review presents the main results on the current knowledge of the effects of NPs and plasticizers on lung cells, as assessed with the use of in vitro cell culture techniques. From the selected studies (n = 10), following the PRISMA approach, it was observed that cell viability was the most frequently assessed endpoint and that most studies focused on epithelial cells and exposures to polystyrene (PS). It was observed that exposure to NPs or plasticizers induces cytotoxicity in a dose-dependent manner, regardless of the size of the NPs. Furthermore, there is evidence that the characteristics of NPs can affect the toxic response by promoting the association with other organic compounds. As such, further in vitro studies focusing on the combination of NPs with plasticizers will be essential for the understanding of mechanisms of NPs toxicity.

Authors: Sánchez Villalón Dayana , Valdés Fernando , Andrial Yolanda , Giralt Angela
Published: July 2022

The noninvasive Balistocardiogram (BCG) signal is the recording of body movements due to heartbeat and blood flow through major arteries. This signal provides enough information to calculate the heart rate and its variations over time. The present paper proposes the design of a prototype of a low-cost electronic system to record the BCG signals acquired by means of a triaxial accelerometer and gyroscope. For the design of the system, an Arduino development board, the 9-axis MPU-9250 sensor (accelerometer, gyroscope and magnetometer), and the free software RealTerm are used. The system is connected by a USB port to a personal computer from where the entire system is governed.

A model of the system was built and tested successfully with arbitrary signals, checking the correct functioning of the system and recording the data in a text file for later analysis.

El cambio climático y el Antropoceno plantean numerosos desafíos para todos los sectores de la humanidad. Desde la antropología, uno de ellos es como utilizar el profundo conocimiento situado sobre las relaciones humano-ambiente para la adaptación al cambio ambiental acelerado, en especial de las comunidades de frontera que son a la vez el objeto de estudio tradicional de la disciplina y los principales afectados por el deterioro ambiental. Se presenta entonces la construcción de nicho como una forma holística de integrar estos conocimientos y se presenta el ejemplo del Gran Chaco. Para ello se discuten tanto prácticas pasadas de domesticación del paisaje, como las principales modificaciones actuales y se analiza una problemática socioambiental reciente: la inundación de la comunidad Toba de Sombrero Negro de 2018. Por último, se describen proyecciones climáticas para el área y hacemos un llamado a una antropología biológica que sirva para vivir en el Antropoceno.

Authors: S Bhuvaneswari
Published: July 2022

Sangam Songs and epics illustrate how the ancient Tamils ​​traded well within and outside the country. In the post-Sangam period, during the period of the Epics, there were bartering methods in the domestic trade. Business flourished in the development of cities. Silappathikaram confirms that every commodity was traded on every street in the cities. From the sale of their products by the common people to the sea trade, evidence could be found. Business activities could also be noticed in Manimegalai following Silappathikaram. Small-scale business practices could be found in the cities. Similarly, professional businesses were also appreciated. People going abroad and doing business using the vessels known as Bengal could correspondingly be observed. The verses of Manimegalai are a demonstration of the fact that they exported and imported expensive goods.

Grammar or Grammatical syntax forms the crux of the language. Grammar is an essential one not only in Tamil but also for all the world languages. Tamil language is one of the oldest surviving languages in the world. Any language can be refined language provided that language will be spoken by a large group of people and also it should heaviest own literariness. Among the languages spoken in India Tamil, Telugu, Konda, Tulu and Coorg forms the Dravidian linguistic family group. They are identified as the refined languages from the Dravidian group. Both the language and the literatures contributes languages. There are lot of literary works and linguistic works and linguistic works are published during the various time periods. There are various literary works are published after the Publication of Tholkappiam. These literary marvels Portrays the lifestyle, culture, tradition and socioeconomic setup of the people. Those literary works distinguishes the lifestyle and social practices of that people as ‘Agam’ and ‘Puram. Though this we can easily identify that the people follow both ‘Agam’ and ‘Puram’ form of lifestyle. Events containing private affairs are confrains as ‘Agam and War, Valour, Pride and charity forms the ‘Puram’. Tamil Grammar is divided into Agapporul and Purapporul. Literary works based on Purapporal focused on the events based on outer lifestyle of the people. Purapporul can be identified as Seven and Twelve. Vetchithinai is defined as the capturing of cows and cattle breeds. The formation or the beginning of the Vetchithinai is because of the competition between the other two thinais like ‘Palai’ and ‘Mullai’. We can assumed that Vetchithinai is formed based on this competition. This research article clearly shows the difference between the Vetchithinai which is portrayed in Tholkappiam and the Vetchithinai which is portrayed in Purapporal Venbamalai and its developments in that thinai.
Internet of Things and the Implication of Legal Risks and Solutions
Authors:   LAW RESEARCH INSTITUTE CHUNGBUK NATIONAL UNIVERSITY, Kim Yong Eui
Published: July 2022

So far the Internet has been conceived as the network of people connected to one another. Recently, a lot of things works in connection with one another connected via the Internet. Thus this Internet is called Internet of Things(IoT). The things include not only the electronic devices for personal use such as smartphones and notebooks but also the variety of home appliances, cars, airplanes and even the satellite in the space. The things in the IoT are working based upon the most important two technologies, which are Artificial Intelligence and 5G Telecommunication Technology. Though IoT can be defined a bit differently by scholars and institutions, it is a common understanding that AI and 5G Telecommunication are the key elements. On one hand IoT’s capacity to sense, collect, analyze the informations and make decisions in a very high speed and effective way, makes possible the smart home, smart factory, smart city and even the smart government. On the other hand, it may also generate high risk and problems that it makes personal information leak and misused, person’s privacy is invaded, and even the national security can be threatened.
The goals of benefiting IoT at the same time protecting people from the risks caused by IoT could be achieved through variety of efforts including setting up appropriate policies and enacting rules and regulations. This article addressed the alternative solutions for the achievement of the goals such as making soft laws, implementing governance process, and the application of blockchain. In sum, with all the pros and cons, this article strongly recommends people (including corporations, consumers, and other groups and associations), as the members of the community they belong to, that they adopt their own soft law best fit for their purpose and community environment to regulate themselves first and to make the soft law to regulate the society general as a de facto binding rules. While doing so we may go through the governance process to harmonize the conflicting interests of the constituents of the society and also adopt the new technology such as blockchain to strengthen the practicability of the soft law at the same time.
Any soft law standards regarding the IoT should be purported to assure individuals that their data will not be misused or hacked, and that they facilitate trust and communication, and avoid the premature and heavy-handed stifling of innovation. Soft law can help these technologies proliferate while giving people the confidence that, contrary to the current belief, the benefits of the IoT far outweigh the risks. Soft law for IoT can be enhanced by convening a multistakeholder process, as one of the public governance process, to develop best practices for protecting the privacy and security of IoT data, including implementing security by blockchain solutions for the IoT.
Legislative Status and Judicial Practice of the Punitive Damage Compensation System in China
Authors:   LAW RESEARCH INSTITUTE CHUNGBUK NATIONAL UNIVERSITY, Piao Ren Jie , Lee Jae Mok
Published: July 2022

Changes and progress in social phenomena such as politics, economy, and culture have a lot of influence on the state's legislative policy. In China, the punitive compensation system, which was introduced to deter and prevent malicious illegal activities and to protect victims thicker since the end of the 20th century, has been widely expanded from food, medicine, and product accidents to intellectual property rights. The punitive damages system has been applied by individual legislation or judicial interpretation, but the first integrated civil law implemented in 2021 adopted punitive damages as one of the new rights relief methods.
Among all civil cases, the proportion of litigation cases claiming punitive damages is insignificant at present. However, as the area to which the punitive compensation system can be applied is expanding significantly, related lawsuits are expected to increase significantly in the future. In order to implement the legislative purpose of the punitive compensation system and maintain a stable judicial order, above all, it is necessary to determine the multiple of compensation that can secure fairness and equity.
As with the provisions of some laws, if the gap in the scope of the multiple of punitive compensation is excessively large, it is necessary to adjust it reasonably because the discretion of the judge may intervene. It is necessary to reasonably adjust this, and in order to secure the effectiveness of the system, a realistic alternative to increase the execution rate of the judgment should be prepared. We look forward to the accumulation of precedents while paying attention to China's continuous legislative efforts and changes in judicial practice.
A Critical Study on the Regulation of Contracts under the Occupational Safety and Health Act
Authors:   LAW RESEARCH INSTITUTE CHUNGBUK NATIONAL UNIVERSITY, Jung Jin-Woo
Published: July 2022

Industrial accident prevention developed countries such as the UK, Germany, Japan, and the United States do not take the view that poor safety and health management of work, whether directly managed or contracted, is a problem and that the work itself is bad. Therefore, no regulations such as contract prohibition and contract approval stipulated in the All-Revised Occupational Safety and Health Act in Korea are found. In addition, it is commonly found that developed countries for industrial accident prevention impose obligations suitable for the status and role of contractors on the premise that contractors do not have a direct employment relationship with contractor workers.
Although safety and health regulations for contracts vary slightly depending on advanced industrial accident prevention countries, contractors are generally obligated to manage facilities, machinery and facilities, select qualified contractors, cooperate and coordinate with contractors, guide and supervise contractors, and guarantee sufficient cost and air. Like Korea's fully revised Occupational Safety and Health Act, no legislative example has been found that uniformly stipulates the same obligations as the contractor.
Clearly establishing roles and responsibilities in industrial safety and health is a basic safety and health principle for the smooth implementation of industrial safety and health measures. This safety and health principle applies not only to the inside of the organization, but also to legal regulations. Even if safety and health regulations for contracts are strengthened outwardly, failure to faithfully reflect these principles in the legislation will only cause a lot of cost and confusion in the industrial field and make it difficult to operate as effective regulations.
The reason why the Occupational Safety and Health Act has not achieved much in preventing industrial accidents for contractors despite strengthening safety and health regulations for contractors than any other country internationally is due to lack of content that does not conform to law principles and safety principles.
Therefore, it can be said that it is very urgent to reorganize the legal system for contracting internationally in order to achieve practical protection and accident prevention for contractors.

Published: July 2022

In the years of the commemoration of the bicentennial of the Independence of Peru, it’s necessary to remember it through events that occurred in these years of political chaos. Precisely, this work is contextualized in one of these events: the elections of the town councils ordered by the Constitution of Cádiz. During this period, the press explains how it’s a medium in which not only the arrival of Cadiz regulations is manifested, but also in which different personalities express their opinions, this is due to the fact that a freedom of the press was enacted in Latin America. In that sense, a debate arose about whether or not clerics could be elected to political office because of a controversial election in Lima, so our goal is to use the publicly exposed arguments in favor. To capture this debate, we’ll use El Verdadero Peruano, a moderately liberal newspaper that was in force during 1812-1813, under the protection of Viceroy Abascal, and whose objective was to highlight the benefits of the Constitution and frequently published information related to it.

Herein, we report a rapid one-step synthetic method using microwave irradiation for growing magnetite nanocrystals on reduced graphene oxide sheets. This developed strategy allows decorating graphene sheets with magnetite nanocrystals of well-defined morphology as cubes using microwave-driven reduction of iron chloride using hydrazine hydrate as a reducing agent. The size and shape control was achieved via fine-tuning of the reaction conditions. The obtained results demonstrate the applicability of this microwave synthetic approach to control the morphology of the magnetite nanocrystals anchored on graphene sheets. Moreover, graphene sheets will enhance the nucleation and growth of magnetite nanoplates anchored on graphene. This approach can be used as a synthetic tool to synthesize a wide variety of metal and metal oxide architectures on graphene. This approach also provides plenty of advantages like catalyst recyclability, mild reaction conditions, easy separation, reproducibility, and minimization of agglomeration effect that cause the decrease in the catalyst catalytic activity.

"Artificial intelligence (AI) technology is creating a new reality in daily life with e.g., smart home functions. This in turn has a major impact on both the socialisation processes of children and communication behaviour in family. The increasing technology-driven saturation of our everyday routines with AI is a crucial challenge for educational institutions. However, looking at AI in pedagogical work in kindergartens from a scientific perspective, the topic still has some research gaps. Only a few articles, describe efficient education concepts aiming at fostering AI literacy (cf. Chen et al., 2020; Kandlhofer et al., 2017). In Early Childhood Education (ECE) practice, however, there are many reservations about technology, digital media, and AI in particular (Mertala, 2017). Nevertheless, it is imperative that pedagogically trained professionals understand in depth the implications that arise from the interaction between humans and AI. Within the framework of the project, which is focused on pedagogical practice, educators are encouraged to deal with the topic of AI on the one hand and to test concrete implementation possibilities with didactic materials, so-called toolboxes, on the other. In this way, the use of AI can become a key competence both in pedagogical professional training and in the educational biography of children. Consequently, the aim of I’m not a robot-project is to design transferable and practical modules within the further training of educational professionals to enable an active, creative, and conscious use of AI-based technologies throughout Europe. Furthermore, the goal is to develop and test innovative didactic methods regarding AI teaching and learning materials. The EduSpace Lernwerkstatt -a working unit of the Free University of Bolzano- will conduct the mixed-method study in close cooperation with the project partners, who will all carry out development and testing independently and with country-specific characteristics. The ultimate aim is to develop training programmes for educators that will enable them to integrate current technological developments into their everyday work in a meaningful way."
MENTORING STUDENT TEACHERS FOR SELF-DIRECTED PROFESSIONAL LEARNING THROUGH THE USE OF E-PORTFOLIOS DURING TEACHING PRACTICE
Authors: Thabane Ratokelo Willie
Published: July 2022

"Teaching Practice is a critical phase of teacher education that provides opportunities for student teachers to reflect on the development of their teaching philosophies and put them into action. Self-directed learning pertains to a process where these students take responsibility for their own learning by setting outcomes, choosing material or human resources, selecting appropriate learning strategies, and evaluating their learning. E-portfolios as learning tools can be utilized to facilitate the development of skills for self-directed learning. Good quality mentoring in schools contributes to the development of critical professional skills of student teachers and ensures the best quality learning experiences for pupils. This paper is arranged as an ideas paper that seeks to explore the intersections between mentoring, self-directed professional learning of student teachers and the use of e-portfolios during teaching practice. The most common trends on these topics will be described and intersections identified, thereby exploring how self-directed learning could be supported by the use of e-portfolios and good quality mentoring. Findings showed that e-portfolios are practical tools for self-directed, reflective and collaborative professional learning. Further findings show that formal mentoring programs are essential to meet student teachers professional learning needs. These findings will encourage mentor teachers to optimally use e-portfolios to enhance student teachers self-directed professional learning."
USING A LEARNER-BASED ACTIVITY APPROACH IN DEVELOPING SCIENCE TEACHERS’ READINESS IN INQUIRY-BASED LEARNING

"The South African science curriculum expects secondary school teachers to adjust their ways of teaching to include inquiry-based learning that endorses learner-based activities. The learner-based activities refer to the processes of learning by doing where learners are not passive, but are rather encouraged to actively participate in their own learning experiences. This paper is necessitated by the limited literature that exists within the South African context about inquiry-based learning, which reveals that the implementation of learner-based activities continues to be a challenge for many teachers, especially in rural schools. Hence, during the teacher training program, the Physical Science teachers were engaged in various learner-based practical activities which involved problem-solving, which is a crucial component of inquiry based learning. This paper therefore drew from the constructivist theory (Vygotsky,1975; Piaget,1980) as lens to answer the leading research question which asks: “To what extent are the science teachers demonstrating readiness of the use of inquiry-based learning in their classrooms after participating in the training program?”. Thus, a mixed method design was adopted where data was collected using as well as pre and post questionnaires to establish the Physical Sciences in-service teachers’ beliefs and experiences towards their readiness in implementing inquiry-based learning in their classrooms after the teacher development program in one of the education circuit in rural Kwa-Zulu Natal province, in South Africa. The findings of this study indicates that the in-service teachers in this district had an impactful experience which positively shifted their attitudes towards their readiness of the use of inquiry based learning when teaching Physical Sciences."
PROMOTING SELF-REGULATED LEARNING IN NATURAL SCIENCES TEACHING THROUGH TECHNOLOGY INTEGRATION
Authors: Ramaila Sam
Published: July 2022

"The advent of the Fourth Industrial Revolution presents enormous opportunities for teachers to embrace digital transformation. The adoption of innovative pedagogical strategies is central to coherent development of scientific literacy in science classrooms. Coherent development of scientific literacy in science classrooms requires teachers as key agents of educational change to embrace pedagogic innovation. This study examined the role of technology integration as a sustainable means to promote self-regulated learning in Natural Sciences teaching in South African township schools. The study adopted a mixed-method approach as part of exploratory descriptive survey design and involved purposively selected teachers from South African township schools as participants. Quantitative data was collected through the administration of a survey questionnaire with the participants while qualitative data was collected through semi-structured interviews and classroom observations. Key findings demonstrated that technology integration plays a pivotal role in the promotion of self-regulated learning in Natural Sciences teaching. Theoretical implications for technology-enhanced learning are discussed."

Apresentam-se aspectos da produção intelectual e do pensamento da professora Amélia Americano Domingues de Castro (1920-2020). A docente se formou e atuou na Faculdade de Filosofia, Ciências e Letras (FFCL) da Universidade de São paulo (USP), desde 1942 até a sua aposentadoria. Se destacou por introduzir as ideias de Jean Piaget no curso de formação inicial docente em Geografia e História à época. O curso foi pinoneiro na formação docente em nível superior no Brasil, nele Amélia ministrou pela primeira vez a disciplina de Didática da Geografia. Desta forma, temos como objetivo de pesquisa destacar as bases teóricas de seu pensamento apontando, dentre sua produção intelectual os estudos que divulgaram as bases que fundaram um modo de pensar o ensino na área das Ciências Humanas, com destaque à Geografia. Enquanto especialista em Didática a professora Amélia foi pouco notada na produção sobre o ensino de Geografia até o momento. Assim, resgatamos este fato importante para a história da disciplina escolar Geografia, fomentando o debate sobre o processo de ensino-aprendizagem dos conceitos geográficos, a partir dos estudos que apontam a superação da idealização dos métodos de ensino em detrimento dos aspectos psicológicos, cognitivos, moral, social e cultural do processo de ensino-aprendizagem. Neste sentido a professora Amélia deixou um legado aliado a matriz caracterizada pela orientação piagetiana do século XX, que teve inúmeras variáveis, certamente replicadas por seus ex-alunos como Aziz Ab’Sáber e Lívia de Oliveira. Por fim, as bases teóricas do pensamento da professora Amélia constituem um legado à Didática da Geografia.
