Patient and Public Acceptance of Digital Technologies in Health Care: Protocol for a Discrete Choice Experiment
Authors: Fischer Ann-Kathrin , Mühlbacher Axel C
Published: August 2023

Background

Strokes pose a particular challenge to the health care system. Although stroke-related mortality has declined in recent decades, the absolute number of new strokes (incidence), stroke deaths, and survivors of stroke has increased. With the increasing need of neurorehabilitation and the decreasing number of professionals, innovations are needed to ensure adequate care. Digital technologies are increasingly used to meet patients’ unfilled needs during their patient journey. Patients must adhere to unfamiliar digital technologies to engage in health interventions. Therefore, the acceptance of the benefits and burdens of digital technologies in health interventions is a key factor in implementing these innovations.

Objective

This study aims to describe the development of a discrete choice experiment (DCE) to weigh criteria that impact patient and public acceptance. Secondary study objectives are a benefit-burden assessment (estimation of the maximum acceptable burden of technical features and therapy-related characteristics for the patient or individual, eg, no human contact), overall comparison (assessment of the relative importance of attributes for comparing digital technologies), and adherence (identification of key attributes that influence patient adherence). The exploratory objectives include heterogeneity assessment and subgroup analysis. The methodological aims are to investigate the use of DCE.

Methods

To obtain information on the criteria impacting acceptance, a DCE will be conducted including 7 attributes based on formative qualitative research. Patients with stroke (experimental group) and the general population (control group) are surveyed. The final instrument includes 6 best-best choice tasks in partial design. The experimental design is a fractional-factorial efficient Bayesian design (D-error). A conditional logit regression model and mixed logistic regression models will be used for analysis. To consider the heterogeneity of subgroups, a latent class analysis and an analysis of heteroscedasticity will be performed.

Results

The literature review, qualitative preliminary study, survey development, and pretesting were completed. Data collection and analysis will be completed in the last quarter of 2023.

Conclusions

Our results will inform decision makers about patients’ and publics’ acceptance of digital technologies used in innovative interventions. The patient preference information will improve decisions regarding the development, adoption, and pricing of innovative interventions. The behavioral changes in the choice of digital intervention alternatives are observable and can therefore be statistically analyzed. They can be translated into preferences, which define the value. This study will investigate the influences on the acceptance of digital interventions and thus support decisions and future research.

Study on the Effect of Patients’ Continuous Usage on Doctor-Patient Relationship in Online Medical Community (Preprint)
Authors: Zhang Shuangzhu , Peng Yubo , Ju Chunhua , Zhang Qi
Published: August 2023

BACKGROUND

At present, there is a serious lack of trust between doctors and patients in China, constantly leading to various violent attacks on medical workers all over the nation. How to improve doctor-patient relationship is an urgent issue to be explored, considering the conjunction facts of insufficient and uneven allocation of medical resources, poor doctor-patient communication, as well as much more doctor-patient disputes.

OBJECTIVE

the paper is aimed to explore effect of patients’ continuous usage on doctor-patient relationship, in order to get insights to improve doctor-patient relationship during actual doctor-patient interactions.

METHODS

Based upon Patient-Physician Partners, from the perspective of three types of communication during patients’ continuous usage of online medical communities, the paper builds the model of effect of continuous usage on doctor-patient relationship, analyzing deeply paths to improve doctor-patient relationship.

RESULTS

The results show that doctors actively providing information, doctors passively providing information and patients actively providing information all have significant and positive effect on doctor-patient relationship.

CONCLUSIONS

In real doctor-patient interactions, on the one hand, doctors shall give full play to the subjective initiative to positively interact with patients, providing medical information or emotional value. On the other hand, patients should also take the initiatives to provide accurate health or disease information to improve accuracy of doctors' disease diagnosis, so as to provide treatment plans that are more in line with patients' needs. Benign doctor-patient interaction can effectively release tensions of current doctor-patient relationship and further enhance practical values of online medical services.

Authors: Jaajpera Tejaswini , Bharti Priya , Baragi Lalita Vithal , M. Rajaneesh Kolchar
Published: August 2023

It has been acknowledged that the poor and the impoverished are the most vulnerable to climate change worldwide, and when we consider gender, women are more vulnerable to climate change than males, and as a result, they suffer the most. Because data collectors collect information from household heads, who are primarily men, these women are left out of the data collection process. According to the SDG Report 2022, this is one of the primary difficulties we are now dealing with. For the study, we selected the Indian cities of Jaipur and Ayodhya, and we conducted a qualitative survey of women from underprivileged families, including families Below Poverty Line. The impact of climate change on women's lifestyles, disease transmission, trends natural disasters, food consumption, daily work patterns, changes in traditional knowledge, and why it is important to take action for India’s sustainable development are all discussed in this paper. This research will help raise awareness of the regional NGOs and give insight into how to frame policies and initiatives that support women. This research will also shed light on areas with comparable temporal patterns, such as Jaipur and Ayodhya, in other parts of the world.
DETECTION PROCESS OF ENERGY LOSS IN ELECTRIC RAILWAY VEHICLES
Authors: Fischer Szabolcs , Kocsis Szürke Szabolcs
Published: August 2023

The paper deals with the detection process of energy loss in electric railway hauling vehicles. The importance of efficient energy use in railways and cost-effective rail transport tendency toward regenerative braking energy are considered. In addition, the current situation and improvement opportunities to achieve efficient energy use are examined. Seven measurement series were performed with scheduled Railjet trains between Hegyeshalom and Győr railway stations in Hungary. This railway section is related to the Hungarian State Railways' No. 1 main railway line (between Budapest-Kelenföld and Hegyeshalom state board), which is a part of the international railway line between Budapest and Vienna (capitals of Hungary and Austria, respectively). This double-track, electrified railway line with traditional ballasted superstructures and continuously welded rail tracks is important due to the international passenger and freight transport between Germany, Austria, and Hungary. The value of the regenerative braking energy can be even 20-30% of the total consumed energy. This quite enormous untapped energy can be used for several aims, e.g., for comfort energy demand (air conditioning, heating-cooling, lighting, etc.) or energy-intensive starts. The article also investigates the optimization of regenerative braking energy by seeking the energy-waste locations and the reasons for the significant consumption. The train operator's driving style and habit have been identified as one of the main reasons. Furthermore, train driver assistance systems are recommended to save energy, which is planned for future research.

This paper presents the results of an investigation conducted on wire electric discharge machining (wire-EDM) of miniature ratchet gears. Effects of three important process parameters spark duration, ‘Ton’, spark-off-duration ‘Toff’, and wire tension ‘WT’ on surface quality, i.e., mean roughness depth ‘Rz’ and productivity, i.e., material erosion speed ‘MES’, have been investigated by conducting seventeen experimental trials. Both Ton and Toff have been identified as the significant parameters. Further, an optimization of wire-EDM parameters resulted in simultaneously best compromise values of Rz 5.30 µm and MES 6.75 mm/min and is achieved the following cutting regime: Ton 1.5 µs, Toff 42.5 µs, and WT 1500 g. At the end, surface quality study has been conducted to evaluate the tribological fitness of the miniature ratchet gear machined at optimum combination of wire-EDM parameter values. It was investigated that the generation of uniform and shallow craters on the flank surfaces of ratchet gear machined at optimum values of parameters, imparted smoother bearing area curve and lower coefficient of friction. The profile and flank surface of the ratchet gear also found free from cracks, burrs, and dirt.

Tribolium castaneum is devastating cosmopolitan insect pest of stored grain. The present study investigated the impact of three insect growth regulators on different life stages of T. castaneum. Percent mortality (%) induced was observed at 0.75. 1.25, 2.5, 5, 10, and 20 ppm doses of each IGR after 7, 14 and 21 day exposure. In addition to larval and parental mortality, progeny suppression data was also recorded. The larvae of the 2nd instar were more susceptible to lufenuron, with mortality reaching 100% at 10ppm even after a 14-day interval. In the case of pyriproxifen, 2nd instar did not responded to all dose rates until 14 days however 21 days, statistically corresponding 2.5 to 10 ppm dose rates was detected. At 20 ppm, methoxy fenazide resulted in 92 percent mortality of 2nd larval instar mortality, and the larvae responded to all dose rates at all exposure intervals that varied significantly among themselves. The mean mortality of the 4th instar larvae at 20 ppm for lufenuron after a 21-day interval was 90%, which was not significantly different from the mortalities (62 and 80%) at the same dose rate after 7 and 14 days, respectively. All the IGRs were very effective in progeny suppression (>80%) and complete progeny suppression (100%) was observed in adults treated with methoxyfenazide and lufenuron at 2.5 and 10 ppm doses, respectively. It is concluded that all the screened IGRs were effective in progeny suppression and in some cases, complete progeny suppression was achieved

Authors:   Universidad de Indiana, Gould Jeffrey L.
Published: August 2023

A finales de la década de los 70s, el movimiento obrero salvadoreño proporcionalmente era entre los grandes y mas militantes en América Latina. El libro narra su trayectoria en esos años y su declive bajo la represión terrorista y su renacimiento parcial bajo el gobierno demo-cristiano entre 1984-1987, enfocando el caso de Puerto El Triunfo, puerto camaronero en el departamento Usulután, cuando el rubro de camarones era fuente principal de divisas. Unos 1500 trabajadores sindicalizados mayormente mujeres se transformaron desde la pasividad a la exitosa militancia bajo la bota del régimen militar. En 1980, los escuadrones de la extrema derecha mataron o exiliaron a la dirigencia local. El libro también enfoca las relaciones de género entre las trabajadoras de las plantas y los pescadores, decisivas en su historia en los 80 cuando existía la posibilidad de formación a una gran cooperativa que hubiera representado una alternativa local al neoliberalismo al cierre de la industria camaronera.

Authors: R Rathna. , V Pushpalatha. , M. A Bhagyaveni.
Published: August 2023

Abstract: The fifth Generation of communication has to support many applications like the Internet of Everything (IoE) and Machine Type Communication (MTC). The proposed universal filtered multi-carrier (UFMC) technique is one of the best techniques for fifth-generation (5G) communication. UFMC is expected to achieve low latency, robustness against synchronization errors and frequency offset, short-packet burst support, and reduce out-of-band (OoB) radiation that leads to higher spectral efficiency. Although the UFMC system offers many advantages as mentioned before, being a multicarrier transmission technology, it suffers from a high peak-to-average power ratio (PAPR), which degrades the efficiency of the HighPower Amplifier (HPA) and makes the UFMC transmitter inefficient. Therefore, an optimum PAPR reduction technique to reduce the high PAPR of the UFMC system has to be proposed. The proposed technique is a hybrid technique that consists of a combination of Generalized Chirp-Like (GCL) precoding and Selective-Mapping techniques (SLM). A comparative analysis of the performance of Generalized Chirp-Like precoding methods, SLM, and hybrid methods are by CCDF of the PAPR and the bit error rate (BER) and simulation results show that proposed SLM based GCL UFMC outperform the conventional techniques
Cross-Layer Based QoS Aware Load-balancing Multi-Path Routing Protocol over Wireless Multimedia Sensor Networks
Authors: Chiwariro Ronald , Lokaiah Dr. P.
Published: August 2023

Abstract: Currently, the utilization of WMSNs in different real-time and non-real-time applications requires an excessive amount of bandwidth for reliable data delivery. The unique features of WMSNs are significantly challenging in satisfying the QoS requirements in such application-specific environments and balancing the traffic load among the devices. The provision of reliable multipath routing is a cornerstone in fulfilling the QoS requirements of WMSNs. Selecting multiple optimal paths between a source and destination based on peculiar routing metrics enhances the performance of QoS routing. Generally, routing protocols exploit several routing metrics, such as delay, remaining energy of nodes, hop count, available bandwidth, and packet loss rate in path selection to attain high reliability in data delivery. Many existing routing protocols only consider the network layer parameters, whereas it lacks focus on the data link and physical layer parameters, which creates a severe impact on the degradation of QoS. In addition to that, varying bandwidth channels create interference in multimedia data delivery and degrade the network performance. Designing a multipath routing protocol by considering cross-layer parameters offer a promising solution to optimize the WMSN performance. In cross-layer design, diverse protocol layers support the routing decisions adaptively by perceiving the dynamic characteristics of the wireless medium, resulting in fair use of scarce resources with high QoS. A Cross-Layer Based QoS Aware Load-Balancing Multipath Routing Protocol over Wireless Multimedia Sensor Networks was the goal of the study's five design objectives. The study and analysis of QoS and cross-layer-based routing algorithms for WMSNs was the initial goal. Secondly, a Deep Learning prioritization-based packet classifier to divide traffic according to priority. To ensure fair resource consumption and distribution of multimedia traffic, the third goal was to design and create a cross-layer optimizer model for optimal multiple disjoint route selection using machine learning techniques. The development of a cutting-edge channel-scheduling algorithm was goal four. It was designed to efficiently assign low-interference channels to communication devices in order to lower the packet drop rate in real-time packet delivery. Last but not least, a security method for Wireless Multimedia Sensor Networks' Cross-Layer based multipath routing protocol.

Abstract: Healthcare changes dramatically because of technological developments, from aesthetics and antibiotics to magnetic resonance imaging scanners and radiotherapy. Future technological innovation is going to keep transforming healthcare, yet while technologies (new drugs and treatments, new devices, new social media support for healthcare, etc) will drive innovation, human factors will remain one of the stable limitations of breakthroughs. No predictions can satisfy everybody; instead, this article explores fragments of the future to see how to think more clearly about how to get where we want to go. Significance for public health technology drives healthcare more than any other force, and in the future, it will continue to develop in dramatic ways. While we can glimpse and debate the details of future trends in healthcare, we need to be clear about the drivers so we can align with them and actively work to ensure the best outcomes for society as a whole.

Published: August 2023

The low current density impedes the practical application of microbial
electrosynthesis (MES) for CO2 fixation. Engineering the reactor design
is an effective way to increase the current density, especially for
H2-mediated MES reactors. The electrolytic bubble column MES reactor has
shown great potential for scaling up, but the mixing and gas mass
transfer still need to be enhanced. Here we introduced an inner draft
tube to the bubble column to tackle the problem. The addition of draft
tube resulted in a 76.6% increase in the volumetric mass transfer
coefficient (kLa) of H2 and a 40% increase in the maximum current
density (337 A/m2). The computational fluid dynamics (CFD) simulations
showed that the addition of draft tube enhanced mixing efficiency by
enabling a more ordered cyclic flow pattern and a more uniform
gas/liquid distribution. These results indicate that the electro-bubble
column reactor with draft tube holds great potential for industrial
implementation.
EICC: Edge Intelligent Context-aware Caching in Mobile Edge Computing Environment
Authors: Momeni Hossein , Moayeri Mohammad Mahdi , Sebti Ali
Published: August 2023

Mobile Edge Computing (MEC) is an emerging technology aimed at
alleviating network congestion and cloud service delays by caching and
processing user requests at the network edge. Despite its potential,
challenges like limited caching resources and unpredictable user
behavior persist. To tackle these hurdles, a new intelligent caching
approach called Edge Intelligent Context-aware Caching (EICC) is
introduced. EICC addresses resource limitations by considering user,
video, and environmental contexts. The approach encompasses three
algorithms: User Location Prediction (ULoP) for foreseeing user
mobility, User Content Interest Prediction (UCIP) for anticipating user
preferences, and Content Rating Algorithm (CoRa) for evaluating content.
The rated content is cached at predicted user locations, allowing
localized access and minimizing latency. We demonstrate that our
proposed approach is more efficient in terms of cache hit rate,
prediction accuracy, and overall delay.
Analyzing the metal binding of superoxide dismutases from an evolutionary perspective
Authors: Wang Tianwen , Lian Shuaibin , Ye Tao , Zhenglian Xue
Published: August 2023

The rapid accumulation of entries in protein databases makes it possible
to carry out large-scale sequence analysis and to make discoveries that
cannot be sufficiently supported with a small dataset. Multiple sequence
alignment is a representative method for identifying positional
variations in related protein sequences by working with sizable entries.
Despite the convenience of operation brought about by the
straightforward comparison, the widely employed multiple sequence
alignment seldom considers the covariation of two or more sites in a
protein sequence. Such a simplification inevitably sacrifices the chance
to discover knowledge that can better reflect heritable variations in
the long history of evolution. The statistical coevolution analysis
method goes further by focusing on the mutation rate of two positions to
identify the functional correlation, based on which the independent
components (IC) were then clustered into independent sections (sector).
Using this method, we analyzed the metal-binding specificity of
superoxide dismutases (SOD) from different families. The results showed
that the residues coordinating metal ions could be clustered into a
sector. However, the SODs of different families exhibited different
levels of correlation, reflected by the order of the sectors: sector 1
for SODs from families PF09055 (NiSOD, based on the Pfam database) and
PF00081(MnSODs or FeSODs), and sector 2 for PF00080 (Cu/ZnSODs). Such a
distribution of metal-binding residues in sectors was also consistent
with the taxonomic levels of the origins of these SODs, implying the
functional separation of residues responsible for catalysis and
structural stabilization. This study will help to explain that mutations
apart from the active site can also exert pronounced effects on metal
ion binding and provide more targets for engineering the biochemical
properties of SODs.

Purpose: The aim of this study was to examine the current
perceptions in prescription of systemic antibiotics for treating
periodontal and peri-implant diseases. Methods: It was a
descriptive, cross-sectional study involving an electronic survey of a
sample of periodontists from Pakistan. A pre-validated questionnaire was
disseminated to Pakistan Medical and Dental Council registered
periodontists of Pakistan in order to ascertain their prescribing
patterns of systemic antibiotics for various periodontal diseases. These
included plaque-induced gingivitis, aggressive periodontitis, chronic
periodontitis, acute gingival and periodontal conditions, conditions
associated with dental implants, mucogingival surgery and periodontal
regeneration. Results: From the 68 periodontists that responded
to this study, 44 completed the questionnaire and their responses were
analyzed. Prescribing trends of systemic antibiotics varied individually
as well as for different periodontal conditions among the responding
periodontists. Highest rate of antibiotics prescription was recorded for
the management of aggressive periodontitis, which was 95.5%. Succeeding
this were acute periodontal conditions, implant placement surgery,
periodontal regeneration procedures and mucogingival surgery, having a
prescription rate of 93.2%, 79.5%, 50% and 29.5%, respectively.
Combination of amoxicillin and metronidazole, azithromycin, and
amoxicillin were the three drugs of choice for various periodontal
conditions. Conclusion: Based on the results from this survey,
it was deduced that systemic antibiotics are widely prescribed by the
periodontists in Pakistan, with varying rates and patterns for different
periodontal and peri-implant diseases. These results highlight the need
for guidelines and recommendations in the prescription of antibiotics
for various periodontal diseases and peri-implant conditions.
Effect s of pruning types on tree vigor inferred from allometric analysis
Authors: Shimada Hideyasu
Published: August 2023

The effects of two pruning types, crown raising and crown reduction, on tree vigor were inferred from allometric relationships between single-leaf area and single-leaf weight and between total leaf weight and total branches weight. The results suggest that the crown raising type should be recommend rather than the crown reduction type as an improved management practice to maintain tree vigor.
Effects of reservoir operations on glacial turbidity in a hydroelectric reservoir
Authors: Robb Daniel M , Pieters Roger , Lawrence Gregory A
Published: August 2023

Turbidity limits light availability in many glacier-fed lakes and
reservoirs, with far-reaching ecological consequences. We use field
observations and hydrodynamic modelling to examine the physical
processes affecting turbidity in the epilimnion of a glacier-fed
hydroelectric reservoir in response to changes in reservoir operations
(e.g. water level, inflows and withdrawals), and to natural processes
(e.g. particle settling, internal seiching and upwelling). The
combination of cold inflows and deep outlets leads to plunging inflows
and the isolation of the epilimnion; this isolation, along with particle
settling, results in a remarkable clearing of the epilimnion during
summer. We simulate a wide range of scenarios based on 46 years of
historical flows. We find that the water level and inflow rate in spring
control epilimnetic turbidity at the beginning of summer, and this
turbidity is a primary determinant of the turbidity and light
penetration for the rest of the summer. Turbidity during summer is also
impacted by wind-driven thermocline motions. We examine these motions
using wave characteristics diagrams and two-dimensional spectra and
identify the period and wavelength of the two dominant wave modes: the
fundamental internal seiche (≈ 4 days) and
diurnally-forced waves. Occasionally, internal motions are large enough
to upwell turbid metalimnetic water to the free surface at the upstream
end of the reservoir. These upwelling events coincide with peaks in the
inverse of the Wedderburn number. Pulses of upwelled water are advected
downstream, setting up a longitudinal turbidity gradient.
Case Review of Professional Learning Communities supported by a Provincial Office of Education
Authors:   Research Institute of Science Education, Jeong MinSuk
Published: August 2023

Recently, regional educational offices have actively promoted several policies to support professional learning communities of teachers. The purpose of this study was to identify the teachers’ perceptions of participating in the professional learning communities supported by J provincial office of education in Korea. To this end, we analyzed 2,855 free-answer responses and 20 interview records. The results of the analysis are as follows. As a result of the review of the plan of the professional learning community, the scope of the concept that the professional learning community accepts in the school field is too wide and confusing. There is a weak motivation for voluntary participation in professional learning communities. The learning content of the professional learning community is not connected to the school site where as the professional learning community policy focused on short-term quantitative expansion.
To put more, the participants in the professional learning communities provided opportunities for communication among members in school operations, classes, and student management. On the other side of their positive experiences, they were also suffered from some difficulties in supporting the members or the school during the activities due to lack of time.

Recently, the numbers of learners and teachers have been rapidly increased due to the recent rise in the status of Korean language education. This study dealt with exploring the trends and issues related to Korean language education based on the web contents related with Korean language education. The target data set included heterogenous contents such as blogs, news, and academic materials that were accumulated between May 1, 2018 and April 30, 2020 in Naver and Daum sites. For the analysis of semantic networks, the important words were selected, refined, and made into matrix data by calculating their frequencies in terms of text mining. As a result, a total of 37,135 words related to Korean language education were collected, of which the top 70 words were extracted. Data containing the keyword ‘Korean language education’ showed that words such as ‘Korean language, education, certification, foreigner, recruitment, research, Korean language education, acquisition, student, instructor, recruitment’ were highly visible. And the following words such as ‘multicultural, Vietnamese, international, overseas, Chinese, Korean, cultural’ or ‘multicultural, marriage and multicultural family support centers’ were also noted regarding Korean language learners. In sequence, the collected data were analyzed by CONCOR(CONvergence of generated CORrelations) method using UCINET 6. The newly formed 4 clusters were named as ‘Qualification test, Teacher recruitment information, Korean language class, Policy.’ The four categories showed the diverse user groups of Korean language education-related web contents and their main interests. The research results provided the basis for the follow-up research reflecting the diversification of Korean language users.

Published: August 2023

STEAM education, which represents the integrated education in Korea, has a goal to cultivate problem-solving ability and integrated thinking ability based on science and technology. Among the various policies for the spread of STEAM education, supporting the teachers’ research groups is very effective because it is based on the spontaneity of the teachers. In this study, we investigated the features of the STEAM teachers’ research groups in Korea by analyzing the reports of the STEAM Teachers’ research groups selected as excellence. The success of the STEAM teachers’ research groups depended on the capability of the research directing teacher. The research group activities turned out to be more effective when they were organized with the same grade level of students in the same school. In addition, it was noted that coding education has been utilized in many STEAM educational programs as part of science-technology-related contents. The STEAM teachers’ research groups intended to share their experiences and knowledge actively, and offered various training and consulting programs in order to enhance the participating teachers’ professional development. For their quality enhancement of the upcoming events, we suggest that they need to expand the number of leader teachers, reduce the constraints related with the teachers’ research group activities and secure enough time and space for the participating teachers.

This paper aimed at understanding how the learning strategies using SRN (Self-Reflection Note) affected high school students’ mathematics learning attitude, self-directed learning ability, mathematical communication ability. For this purpose, data were collected from 83 students in 4 classes of 2nd graders attending specialized high schools located in small and medium-sized cities in the province. The pre- and post-questionnaire tests were conducted to confirm what changes occurred in the students’ math learning. In addition, satisfaction with math learning was investigated using SRN, and the following results were obtained by supplementing the interview data.
First, classes using SRN elicited positive responses from students in terms of understanding class content, reflecting on math learning, supporting math learning, and recommending the use of SRN to other students. Second, there was no significant change in the effect on affective domains such as confidence, learning motivation, and interest in the mathematics learning satisfaction test using SRN. Third, as a result of the pre- and post-test, there were overall positive changes in the mathematics learning attitude domain, self-directed learning ability domain, and mathematical communication ability domain.

A Digital Ethnography about an Elementary Student's Experience as a YouTuber : Focusing on Changes in Media Literacy Competencies
Authors:   Research Institute of Science Education, Kim Yunkyoung
Published: August 2023

The purpose of this study is to explore implications for media education through digital ethnography about an elementary student's experience as a YouTuber. The participant of this study is the researcher's daughter, a 4th grade elementary school girl. The research period is from January 11 to October 11, 2021, and the research method is a digital ethnography.
The research results are as follows; First, the research participant, name Jang-mi, her ability to produce media contents is developed. Second, her ability to accept media contents has developed. Third, responsibility is created as the subject of media enjoyment of her. The implications of this study is that media literacy requires empirical education of ‘learning while doing’ rather than theory-centered education of ‘learn and do’. And media literacy competency is fostered when ‘reflection’ on media products takes place. Fianlly, it suggests the need for communication between digital natives and digital migrants.
As such, the reflective media enjoyment of elementary student YouTuber, Jang-mi suggests the possibility of cultivating subjective media literacy. In addition, actual-based media education should be conducted at school sites so that media literacy competency can be cultivated as a 'phronesis'.
