Published: October 2023

This article considers the use of a short-circuit rotor asynchronous motor in mini and micro HPP switching to generator mode in the case where the capacitor elements are connected to the stator coil in order to provide reactive power. The main purpose of using an asynchronous motor in generator mode is as follows:
- Low cost of asynchronous motor;
- Ease of Operation work;
- Permanent immutable vine source consumption not to do;
- Ease of holding the frequency in one norm;
- Length of working life.
To operate an asynchronous motor in generator mode, it is required to provide mechanical energy to the shaft of the motor at a speed greater than the nominal rotation of its motor (5%), while it is necessary to use it by connecting the capacitor elements of the required capacity to the stator coil for reactive power consumption of the motor. It is important to correctly select the capacitance of the capacitor elements, incorrectly selected capacitor elements can negatively affect the quality indicators of the electricity being produced. At a time when the current demand for electricity is constantly increasing, the production of quality and affordable electricity using renewable energy sources wisely due to the dwindling natural energy resources is one of the pressing issues, therefore, this article considers measures for using an asynchronous motor in generator mode, gives the necessary data and conclusions. The use of an asynchronous generator in relation to a synchronous generator in Mini and micro HPP leads us to reduce the cost of electricity, therefore, the research work carried out is relevant.

Authors: Stankiewicz Gabriel , Dev Chaitanya , Weichelt Michelle , Fey Tobias , Steinmann Paul
Published: October 2023

Metamaterials open up a spectrum of artificially engineered properties otherwise unreachable in conventional bulk materials. For electromechanical energy conversion systems, lightweight materials with high hydrostatic piezoelectric coupling coefficients and negative Poisson's ratio can be obtained. Thus, in this contribution, we explore the possibilities of piezoelectric metamaterials design by employing structural optimization. More specifically, we apply a sequential framework of topology and shape optimization to design piezoelectric metamaterials with negative Poisson's ratio for electromechanical energy conversion under uniform pressure. Topology optimization is employed to generate the initial layout, whereas shape optimization fine tunes the design and improves durability and manufacturability of the structures with the help of a curvature constraint. An embedding domain discretization (EDD) method with adaptive domain and shape refinement is utilized for an efficient and accurate computation of the state problem in the shape optimization stage. Multiple case studies are conducted to determine the importance of desired stiffness characteristics, symmetry conditions and objective formulations on the design of piezoelectric metamaterials. Results show that the obtained designs are highly dependent on the desired stiffness characteristics. Moreover, the addition of the EDD-based shape optimization step introduces significant changes to the designs, confirming the usability of the sequential framework.

Published: October 2023

This paper analyzes the timing performance of a persistent storage designed for distributed container-based architectures in industrial control applications. The storage ensures data availability and consistency while accommodating faults. The analysis considers four aspects: 1) placement strategy, 2) design options, 3) data size, and 4) evaluation under faulty conditions. Experimental results considering the timing constraints in industrial applications indicate that the storage solution can meet critical deadlines, particularly under specific failure patterns. Moreover, this evaluation method is applicable for assessing other container-based critical applications with timing constraints that require persistent storage.Further comparison results reveal that, while the method may underperform current centralized solutions under fault-free conditions, it outperforms the centralized solutions in failure scenarios.

Published: October 2023

Background
Due to world population ageing and a rise in non-communicable diseases, there is an increased need for rehabilitation services. Rehabilitation nursing in primary health care is an example of an area of high service need that can benefit from more clarity of the role of nurses to optimize rehabilitation interventions for ageing populations. The objective of this scoping review is to describe the role of nurses in the provision of rehabilitation interventions to the ageing population in primary health care.
Methods
A secondary analysis of a scoping review was carried out following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR).
Results
68 studies from high- and upper-middle income countries were included and showed that nurses typically had a managerial and clinical role (76%). They worked in multidisciplinary teams in about half of the studies, most often with physical therapists. In total, nurses provided 355 different rehabilitation interventions and mainly assessed person-centered goals and functioning and provided follow-up visits and case management. Nurses had 117 different job titles and little information was available about their educational background and collaboration with other health workers.
Conclusion
Our scoping review contributes to a better understanding of the key role played by nurses in rehabilitation of the ageing population in primary health care and their collaboration with other health professionals. Matching nurses’ competencies with their level of proficiency is essential to ensure quality rehabilitation care to the ageing population.
Recognizing Good Variational Quantum Circuits with Monte Carlo Tree Search
Authors: Cai Zhiqiang , Chen Jialin , Xu Ke , Wang Lingli
Published: October 2023

Many investigators have recently turned to the study of quantum architecture search since it is laborious to manually design a high-performing quantum model and corresponding training strategies. For some tasks, it is more realistic in practice to search for a model architecture. In this paper, we introduce the Monte Carlo Tree Search algorithm which has achieved great success in classical neural architecture search to find good variational quantum circuits for two real-world tasks of ground state energy estimations and multimodal fusion. We adapt the Monte Carlo Tree Search to the quantum scenario by considering more sophisticated classifiers within the tree nodes to partition the search space into several subregions based on the model performance. The experimental results indicate that our proposed method has the ability to recognize good models from the vast search space in both tasks. More importantly, the discovered variational quantum circuits demonstrate their advantages in fusing multimodal features under the comprehensive consideration of parameter number and performance.
Estimating the mechanical properties of rocks and rock masses based on mineral micromechanics testing
Authors: Liu Xiu-yang , Xu Ding-ping , Li Shao-jun , Duan Shu-qian , Xu Huai-sheng , Jiang Quan , Qiu Shi-li
Published: October 2023

The mechanical properties of rocks, including the elastic modulus and uniaxial compressive strength, play a crucial role in rock engineering design and analysis. However, in specific working conditions such as high-stress rock mass with prominent core discing, heavily jointed rock mass, and extraterrestrial rock mass, acquiring standard cylindrical rock specimens that meet testing requirements can be challenging. To address this issue, we propose an innovative methodology for estimating the mechanical properties of rocks and rock masses based on mineral micromechanical testing. This methodology utilizes the phase-positioned indentation technique and statistical deconvolution indentation technique to determine the micromechanical properties of constituent minerals in rocks. Subsequently, by employing the multiple linear regression technique and generalized means method, the micromechanical properties of these minerals are upscaled to estimate the elastic modulus and uniaxial compressive strength of rocks. Furthermore, the previously estimated properties of rocks are further upscaled using the Hoek–Brown failure criterion and the geological strength index system to estimate the mechanical properties of rock masses. Our findings demonstrate the accuracy of this methodology in estimating the mechanical properties of rocks, validated through comparisons with experimental data and other models. This methodology provides a feasible tool for preliminary predictions of the mechanical behavior of rock masses, particularly in situations where obtaining standard cylindrical rock specimens is challenging.

Authors:   Korea Urban & Real Estate Association, Kim Min Sun , Lee Jae-Su
Published: October 2023

The government has implemented a variety of regeneration projects for old industrial complexes and declined regions. Due to the promotion of policies and projects focused on each target place, however, there is a lack of policy linkages among them. This study intends to categorize old industrial complexes nationwide and analyze the characteristics of each type while considering industrial complexes and surrounding regions. Ten indicators are selected to implement the principal component analysis using data from the national industrial complex status, industrial location information system, and statistical geographic information system. Based on the factor score produced by the principal component analysis, the cluster analysis indicates that there are four types of old industrial complexes: large sustaining and developing complex type, small growing complex type, old declining complex type and region-linked complex type. The old declining industrial complex continues to decline due to weak economy of both the complexes and surrounding areas, and the residential environment. Industrial restructuring and industrial complex regeneration projects are needed to strengthen the competitiveness of the complexes. Regeneration strategies for each type of industrial complex is required in consideration of the physical and economic characteristics of both the complexes and the surrounding areas.

Published: October 2023

The rapid development of Subscription Video on Demand (SVoD) services in Indonesia makes it promising. The change in consumers’ behavior from watching movies through television channels and cinemas to online streaming has encouraged industry players to look for innovation. The research aims to analyze factors influencing the intention to continue using SVoD with Netflix as the case study. The research combines two theories, namely Information System Success (ISS) Model and Expectation Confirmation Theory (ECT). The research also adds an aspect of personalization which is one of the characteristics of SVoD services. There are 623 respondents who have used Netflix’s SVoD service at least once (purposive sampling) to participate in the research. The data are analyzed using the covariancebased structural equation model and facilitated using AMOS 26 program. The results indicate that service quality has a positive effect on confirmation. Then, system quality has a positive effect on perceived usefulness, and confirmation has a positive effect on satisfaction. Moreover, satisfaction, perceived usefulness, and personalization positively affect continuance intention to use SVoD services. Based on these results, the research is expected to contribute to SVoD service providers to evaluate their services so that users have the intention to continue using the SVoD services.

This study investigated the performance of different ionic solvents (NaCl, KNO3, and Na2SO4) in mediating electrolytic decontamination of pesticide-containing wastewaters and established the most suitable ionic solvent that can satisfactorily achieve decontamination of such wastewaters. These were done to find a water-purification technique suitable for the removal of recalcitrant and hazardous trace organic substances from wastewater. Organochlorine pesticide (OCP)-containing wastewaters were constituted according to prescribed modalities. It was observed that complete decontamination of the wastewater was achieved within 2 h of using Na2SO4. The study concluded that the 1.0 M of Na2SO4 solution-mediated electrolytic process was most efficient in decontaminating OCP-containing wastewater.

Authors: Li Youming , Qu Jia , Zhang Haosen , Long Yan , Li Shu
Published: October 2023

To meet the demand of accurate water level prediction of the reservoir in Liuxihe River Basin, this paper proposes an improved long short-term memory (LSTM) neural network based on the Bayesian optimization algorithm and wavelet decomposition coupling. Based on the improved model, the water levels of Liuxihe Reservoir and Huanglongdai Reservoir are simulated and predicted by the 1 h prediction length, and the prediction accuracy of the improved model is verified separately by the 3, 6 and 12 h prediction lengths. The results show that: first, Bayesian optimization coupling can significantly reduce the average absolute error and root mean square error of the model and improve the overall prediction accuracy, but this algorithm is insufficient in the optimization of model extremum; Wavelet decomposition coupling can significantly reduce the outliers in model prediction and improve the accuracy of extremum, but it plays relatively weaker role in the overall optimization of the model. Second, by the prediction lengths of 1, 3, 6 and 12 h, the improved model based on the LSTM neural network and coupled with Bayesian optimization and wavelet decomposition is superior to Bayesian optimization and wavelet decomposition coupling model in overall prediction accuracy and prediction accuracy of extremum.

Authors: Matos Laura Andreina , Velásquez Juan Ramón , Miranda Renato Cézar de , Nabout João Carlos
Published: October 2023

Each destination can sustain a specific level of acceptance for tourism development and use. Beyond this level, further development may result in socio-cultural deterioration or a decrease in the quality of the visitor experience. This study aims to assess the tourist carrying capacity of the Silvânia National Forest, situated approximately 7 km from the urban center of Silvânia in the Goias State. To achieve this, we used the highly adaptable Cifuentes method to establish field variables based on ecosystem criteria. Our findings indicate that the study area has the capacity to accommodate more visitors than it currently does, and the social correction factor received the most attention due to the diversity of distances between groups and visiting times. It is important to increase the tourist offerings in a way that is appropriate to the characteristics of the territory and fulfills the management objectives without damaging the natural space in order to reach the expected limit of visits. Nevertheless, it is crucial to continuously monitor the local biodiversity because the predicted increase in tourist visits shouldn't have an impact on its preservation.

The chapter presents the main principle on which the proposals of this book
are based. In this principle, the energetic efficiency of pneumatic actuators is strongly
increased by adding an amount of expansion work to the classical work produced by
constant pressure displacement. Such a principle has already been applied in steam
machines at the beginning of the 20th century or in existing pneumatic converters used
as motors for automotive vehicles.
Eurico Thomaz de Lima e o Brasil: interações musicais transatlânticas na primeira metade do século XX
Authors: Paula Rodrigo Teodoro de
Published: October 2023

Ao longo de sua carreira como pianista, compositor e pedagogo, Eurico Thomaz de Lima (1908–1989) cruzou o Atlântico rumo ao Brasil em dois períodos – em 1949 e 1952 – divulgando obras de nomes da música clássica portuguesa de princípios do século XX e estabelecendo relações profissionais e de amizade com destacados nomes da cena musical brasileira, como Villa-Lobos, Waldemar Henrique, Camargo Guarnieri, Barrozo Netto, Najla Jabôr, Carmen Vasconcelos, entre outros. Essas viagens e contatos terão impactos na obra pianística de Thomaz de Lima, mas também no processo de difusão da música clássica brasileira em Portugal, seja através de concertos com obras desses compositores ou através de suas atividades como professor. Testemunhos desse intercâmbio cultural podem ser identificados em partituras oferecidas ao músico português, ou adquiridas pelo próprio, no Brasil, na sua relação epistolar, através de registos fotográficos feitos pelo próprio, nos programas de concertos e em diversas notícias publicadas nos periódicos brasileiros e portugueses. A análise das fontes relacionadas com a sua primeira digressão (1949), com destaque para as que integram o espólio de Eurico Thomaz de Lima, espólio custodiado no Departamento de Música da Universidade do Minho, permitirá reconstituir os processos de intercâmbio supracitados, os seus impactos, as redes de sociabilidades estabelecidas, as razões que permitiram a sua segunda digressão, para além de oferecer novos contributos biográficos sobre o músico português.
Does work-life balance depend on where and how you work?
Authors: Kinman Gail , McDowall Almuth
Published: October 2023

This article reports on a symposium presented in EAWOP, 2009 that examined work-life balance issues in different occupational contexts. During a global recession where developing work-life balance policies may not be considered organizational priorities; we argue that the need for systematic research into work-life balance has never been greater. The findings of the four papers included in the symposium suggest that work-life balance initiatives that are firmly grounded in workplace context and that acknowledge diverse approaches to conceptualising and managing the work-home interface will be more successful than those that assume “one size fits all”.
Towards a total workplace innovation concept based on sociotechnical systems design
Authors: van Amelsvoort Pierre , van Hootegem Geert
Published: October 2023

This article aims at developing a more comprehensive design theory for stakeholders who are involved in design processes aimed at workplace innovation, by starting from sociotechnical design and by exploring how we can broaden that perspective with other approaches, to also cover issues such as Information Technology-design and Human Resources-design. This article will focus on sociotechnical design (STS-D) theory for the design of the division of labour as developed in the Lowlands (Netherlands and Belgium). In addition to STS-D theory, other theories and practices for designing control, coordination and support systems have been developed, such as Lean Thinking, Total Productive Maintenance, Human Resource Management (HRM) theories, Relation Coordination theory, Information and Communications Technologies (ICT) theories, the practice of the New World of Work (time and place independent work) and Sociocracy for participative strategic decision making. In this article, we will outline a start for combining these approaches with STS-D theory to develop a systemic concept of Total Workplace Innovation (TWIN). As such, this article is an essayist and conceptualising approach to organizational design theory.
Detecting who is going to innovate
Authors: Lochner Katharina , Preuss Achim , Justenhoven Richard
Published: October 2023

An important factor for workplace innovation is having creative employees in the workplace. Most tests for assessing creativity are paper-and-pencil-based and require a trained evaluator for scoring. This, in turn, renders scoring time-consuming, expensive, and not entirely objective. The aim of the three studies presented here was to develop an online creativity test that uses a fully automated scoring algorithm, that is optimised for unsupervised settings, and that can be applied internationally by being language-independent. As such, it can be used as a quick and cost-efficient instrument for selection as well as individual and team development purposes.
Battle report from a corporate psychologist: Why inaccurate methods are easier to sell and what we can do about it
Authors: Rajca Grzegorz
Published: October 2023

As a psychologist working in consulting, dealing with various types of organizational research is my daily bread. The amount of low-quality methods and tools lacking adequate validation that I encounter in the business world is staggering. Even more worrying is their popularity in business and their resistance to being replaced by validated methods, even if they are available. For some reason business seems to prefer using questionable tools. This paper explores why such tools dominate the market. Several reasons are discussed for why these methods may have an advantage over those designed and validated by academia. Possible solutions to overcome this problem are also discussed.

Authors: Czarnota-Bojarska Joanna
Published: October 2023

When planning any research in an organization, it is necessary to decide upon the types of personal data to be collected. Ethical research principles suggest that researchers need to ensure participants’ anonymity and confidential treatment of their data. However, researchers tend to collect various types of demographic information which might lead participants to believe that their anonymity could be compromised. This article highlights some methodological considerations aimed at ensuring respondents’ anonymity and confidential treatment of their data. It also presents two examples which highlight some potential problems that might arise when respondents feel that the anonymity and confidentiality of their data are threatened. Finally, the article proposes specific actions researchers can take to increase participants’ trust in them and the employed research designs.

BACKGROUND

Diabetes mellitus is the most challenging and fastest-growing global public health concern. Approximately 10.5% of the global adult population is affected by diabetes, and almost half of them are undiagnosed. The growing at-risk population exacerbates the shortage of health resources, with an estimated 10.6% and 6.2% of adults worldwide having impaired glucose tolerance and impaired fasting glycemia, respectively. All current diabetes screening methods are invasive and opportunistic and must be conducted in a hospital or laboratory by trained professionals. At-risk participants might remain undetected for years and miss the precious time window for early intervention to prevent or delay the onset of diabetes and its complications.

OBJECTIVE

We aimed to develop an artificial intelligence solution to recognize elevated blood glucose levels (≥7.8 mmol/L) noninvasively and evaluate diabetic risk based on repeated measurements.

METHODS

This study was conducted at KK Women’s and Children’s Hospital in Singapore, and 500 participants were recruited (mean age 38.73, SD 10.61 years; mean BMI 24.4, SD 5.1 kg/m2). The blood glucose levels for most participants were measured before and after consuming 75 g of sugary drinks using both a conventional glucometer (Accu-Chek Performa) and a wrist-worn wearable. The results obtained from the glucometer were used as ground-truth measurements. We performed extensive feature engineering on photoplethysmography (PPG) sensor data and identified features that were sensitive to glucose changes. These selected features were further analyzed using an explainable artificial intelligence approach to understand their contribution to our predictions.

RESULTS

Multiple machine learning models were trained and assessed with 10-fold cross-validation, using participant demographic data and critical features extracted from PPG measurements as predictors. A support vector machine with a radial basis function kernel had the best detection performance, with an average accuracy of 84.7%, a sensitivity of 81.05%, a specificity of 88.3%, a precision of 87.51%, a geometric mean of 84.54%, and F score of 84.03%.

CONCLUSIONS

Our findings suggest that PPG measurements can be used to identify participants with elevated blood glucose measurements and assist in the screening of participants for diabetes risk.

Authors: Mohamed Amr , Shaaban Tahany
Published: October 2023

This study investigated levels of metacognitive awareness among Saudi Arabian applied college students, focusing on the impact of gender and academic majors on their writing skills. A total of 90 participants from Information Technology (IT) and Supply Chain Management majors were recruited, and data were collected through the Metacognitive Awareness of Writing Questionnaire (MAWQ). Results showed that participants had a moderate level of knowledge of cognition related to writing skills and a relatively high degree of regulation of cognition when it came to writing. Female students demonstrated higher metacognitive awareness than males, and IT students had higher mean scores on both "knowledge of cognition" and "regulation of cognition" than Supply Chain Management students. These findings have implications for educators and policymakers seeking to promote academic success and metacognitive awareness among college students, especially in terms of developing targeted interventions to improve writing skills.
La activación de la información fonológica en aprendientes de segundas lenguas por medio de imágenes
Authors: Rodríguez Lázaro Alma Luz , Arias Trejo Natalia
Published: October 2023

Investigaciones sobre activación del léxico han mostrado que cuando se escucha una palabra existe una activación de la fonología. Asimismo, estudios en bilingües señalan que la fonología se activa inicialmente para decodificar e integrar la información de las palabras en la segunda lengua (L2). El objetivo central de este trabajo fue describir si la información fonológica de aprendientes universitarios de una segunda lengua sin experiencia de inmersión es activada inicialmente en una tarea de preferencia visual. En la tarea se presentaban de forma simultánea cuatro estímulos visuales (un competidor fonológico, un competidor semántico, un competidor de rasgos visuales y un distractor) relacionados con una palabra en L2 percibida auditivamente. Los resultados revelaron que la información fonológica era activada inicialmente ante la presentación de imágenes, excepto cuando se exhibían palabras escritas. En este caso, los participantes mostraron una preferencia hacia la información de rasgos visuales. Se concluye que la activación de la fonología en la L2 se observa en aprendientes que no han tenido experiencias de inmersión, al igual que lo reportado en estudios con bilingües.

Abstract: India is very fast developing nation, and construction plays vital role in developing the nation. In construction, concrete is the majorly useful material. Fine aggregate used in concrete like traditional UHPC causes several environmental issues like floods due changes the direction of river flow, effect on biological diversity, falling water table also . In current time millions of tons of waste materials disposed in open environment which causes several health as well as waste disposal problems. We can use waste material like Bakelite as the partial replacement of fine aggregate. The purpose of this study is to find whether the use of Bakelite in concrete improve its compressive strength as a partial replacement in conventional M25 grade concrete Mix. From 2010 to 2020, river sand usage in Indian construction sector increased from 630 to 1400 Tons. This type of usage is very harmful for our next generation also that’s why many states in India like Bihar, Tamil Nadu, Madhya Pradesh, Rajasthan, Uttar Pradesh and Maharashtra have banned the river sand mining for use in concrete

This study was conducted to find out foreigners' perceptions and tasks of the settlement environment of free economic zones. The study selected Songdo International City in the Incheon Free Economic Zone as a spatial scope. Based on previous studies and development plans, a framework for analysis was created, and the contents were derived by analyzing based on the results of written interviews with 15 foreigners. Songdo International City in the Incheon Free Economic Zone was developed by encouraging foreign residents to use English as an official language, considering the residential environment of housing, cultural and sports facilities, medical, and education. In particular, problems with difficulty in communication appear in all issues, and it can be seen that conditions different from plans have been created, especially in areas where dependence on the private sector is high. As a result, public intervention in the housing sector, information systems, and environments in the official language, support systems for early resident settlement, and cultural exchanges were proposed to increase multicultural inclusion in the future. This study targets free economic zones developed by a special review of the foreign settlement environment, but this perception of foreign settlement needs to be considered in all regions at a time when foreign population growth is expected in the future.

Published: October 2023

This study synthesized case studies of living labs in small and medium-sized cities among various types of projects that have been carried out by local governments as part of the Ministry of Land, Infrastructure and Transport's smart city development project. In particular, we derived a plan that can be used as a reference when promoting smart city development projects. Smart cities have been in the spotlight around the world as an alternative urban design method to solve urban problems and improve the quality of life of residents. Likewise, smart city development projects are becoming established in local governments through various public offering projects of central ministries. However, although it is recommended to have a bottom-up process of citizen participation in smart city creation, the weight of the discussion is different in each region, so a systematic discussion to standardize it was necessary. Therefore, solving social problems and social demands can no longer be considered only local issues, and this also applies to the creation of smart cities. In the end, in order to operate a smart city living lab sustainably and successfully, it is necessary to organize learning-evolving subject-specific communication activities along with online and offline-based feedback, which is left as a task for the next research.
The Problems of Artificial Intelligence Technology in the Media: Discussions on Watermarks and Identification Measures to Prevent Copyright Infringement and Disinformation by AI Generated Contents

As artificial intelligence technology spreads widely and the level of technology increases, it is causing various social problems. In particular, some artificial intelligence contents are generated so elaborately that it cannot be easily distinguished by general users. If it is not specifically marked as 'content generated by artificial intelligence technology' or 'ai', it may mixed with other contents.
We have had high expectations that artificial intelligence technology would bring unprecedented innovation. Due to artificial intelligence technology, however, the contents created by using artificial intelligence technology in all over the world have faced serious social problems, and efforts are being made to find a solution in various places. In particular, there are cases where facts that do not actually exist are fabricated or distributed, posted, or used as if they were human-made works.
By technological development continues, there will eventually come a moment when artificial intelligence created content and human-created content will be mixed and it will be difficult to distinguish them without a special method. If it becomes impossible to differentiate the value and characteristics of the production process and results of each content or the boundaries between content will become blurred, content creation activities in which humans have invested a long time and effort will gradually shrink.
Korea is pursuing the enactment of the Artificial Intelligence Act to establish policies, including support necessary for the fostering and development of artificial intelligence technology, and to stipulate obligations to protect artificial intelligence service users. Because it takes a considerable amount of time to establish a legal system and apply actual regulations, however, it is moment to discuss identification measures such as watermarks to prevent mis-recognition and confusion regarding artificial intelligence contents that are currently occurring.
If standards are established to distinguish contents using artificial intelligence technology, the differentiation between human-created content and artificial intelligence created content will be maintained and the value of each content will not be damaged. It is also expected to help prevent copyright protection protected by law from being infringed and protect users. Above all, in the future, there is a risk that artificial intelligence content and human-created works will not be distinguished, resulting in misunderstanding and confusion, which is reducing the value of existing works and weakening the sense of protection for them. Therefore, there is a need to seriously discuss countermeasures before these problems become bigger.
