A step-by-step guide to Generalized Estimating Equations using SPSS in dental research
Authors: Lim Hoi-Jeong , Park Su-Hyeon
Published: August 2024

The Generalized Estimating Equations (GEE) approach is a widely used statistical method for analyzing longitudinal data and clustered data in clinical studies. In dentistry, due to multiple outcomes obtained from one patient, the outcomes produced from an individual patient are correlated with one another. This study focused on the basic ideas of GEE and introduced the types of covariance matrix and working correlation matrix. The quasi-likelihood information criterion (QIC) and quasi-likelihood information criterion approximation (QIC_u) were used to select the best working correlation matrix and the best fitting model for the correlated outcomes. The purpose of this study is to show a detailed process for the GEE analysis using SPSS software along with an orthodontic miniscrew example, and to help understand how to use GEE analysis in dental research.

Published: August 2024

The aim of this study was to evaluate the effect of national health insurance coverage of periodontal scaling using the National Health Insurance Service-National Sample Cohort for 2009-2013. After the enforcement of periodontal scaling covered by national health insurance, the number of patients diagnosed with periodontal disease and received treatment, has increased from 35,234 to 99,576 people in the last 4 years. Further, the number of patients who received the treatment of periodontal disease more than once, have also increased to around 69% in 2013 when compared to 2012. Moreover, the number of patients receiving periodontal scaling has been steadily increasing every year. Among the patients who visited hospital for periodontal disease, there has been an increase of 280%. As a result, continuous public relations and long-term research on the effect of periodontal scaling as a prophylactic treatment is necessary.

Authors: Kim Sunil
Published: August 2024

Obturation is a important procedure of root canal treatment. Canal filling should be both provide a hermetic seal for the root canal system and eliminate leakage channel from the oral cavity. Gutta-percha have been the standard material of choice for root canal obturation. Canal filling has been aimed at maximizing the amount of gutta-percha and minimizing the amount of sealer. However recently, single cone technique has been introduced that include calcium silicate-based sealer and single gutta-percha cone. It is important to select an obturation technique that offers consistency and is easy to use. From the standpoint of appropriate technology, the single cone technique is thought to be useful for general dentist.
Understanding and Practice of Eating-Swallowing Disorder
Authors: So Jong-Seob , Ko Sok-Min
Published: August 2024

Eating-swallowing disorder (dysphagia) is a very important functional problem for the elderly, and it has a significant impact on the quality of their life. Because the eating and swallowing processes are affected by oral tissues including teeth, tongue, and oral muscles, it is natural that the dentist as a specialist in oro-facial region, intervenes in the diagnosis and treatment of the disorder. Nevertheless, Korean dentists still lack interest and understanding of dysphagia. In aged society, it is necessary that the dentists understand the functional disorders as well as oral diseases. The purpose of this study is to introduce the evaluation and treatment methods of eating and swallowing functional disorders in order to cope with eating-swallowing disordered patients who are frequently encountered in aged society.
The effect of Silver Diamine Fluoride in preventing dental caries
Authors: Song Ji-Soo
Published: August 2024

Silver diamine fluoride (SDF) is an alkaline topical solution and it derives from the conjunction of silver nitrate and fluoride. It reduces the growth of cariogenic bacteria, inhibits degradation of dentinal collagen, impedes demineralization and enhances remineralization. It is inexpensive due to the low cost of materials and its application to dental surface is very simple and requires relatively short chair time. Previous studies have shown that the dental caries prevention effect of SDF is superior or similar to topical fluoride application. The main disadvantage of SDF is its esthetic result, and it permanently blacken carious enamel and dentin. The use of SDF has not yet been approved in Korea, but it may be helpful to prevent and treat dental caries in patients with special health care needs and uncooperative young patients.

There are various evaluation methods for misfit assessment including clinical methods and laboratory in vitro methods. The clinical misfit evaluation includes radiographic analysis, visual observation, probing, Sheffield test, evaluation with disclosing materials, and screw resistance test. The laboratory in vitro evaluation method includes indirect modelling evaluation and direct metrological visualization. Of the indirect modelling methods, photoelastic stress analysis, finite element analysis, strain gauge analysis, and microbial colonization analysis were reviewed. Of the direct metrological visualization, microscopic analysis, 3-D photogrammetric analysis, coordinate measuring analysis, and radiographic analysis were reviewed. In this review, the characteristics, advantages and disadvantages of each method were evaluated.
Major oral health indicators in mature and middle age
Authors: Cho Hyun-Jae
Published: August 2024

Although the Korea National Health and Nutrition Examination Survey (KNHANES) calculates oral health functional restriction rate and chewing discomfort rate every year, these two indicators are not all indicators of oral health. Therefore, indicators are needed to subdivide by age group and cover dental caries, periodontal disease, remaining teeth, and oral care use. The purpose of this study is to identify the key indicators of oral health in mature and middle age. The average number of existing natural teeth, the rates of 20 or more natural teeth, complaints of chewing discomfort, oral examination, periodontal disease and dental caries, were analyzed using KNHANES VI (2013-2015) as a complex sample. In the age group between 40 and 64, there were 25.2 natural teeth remaining, 91.4% natural teeth retention rate, 23% chewing discomfort rate, 34.7% oral examination rate, 38.7% periodontal disease prevalence, 6.46 the number of caries experience teeth, 21.4% interdental brush usage rate.

Authors: Jung Hoi In
Published: August 2024

Korean society is experiencing a very rapid change in population aging. Oral diseases, including dental caries and periodontal disease, are usually cumulative and make oral health worse with age. Preventing tooth loss through the prevention and treatment of caries and periodontal diseases are essential for retaining oral function later in life. This study aimed to identify the trend in oral health status among elderlies over 65 years old, using major oral health indicators of Health Plan 2020. The fifth, sixth, and seventh Korea National Health and Nutrition Examination Survey (KNHANES V, VI, VII) were used in the present study to estimate the number of remaining natural teeth, the rate of 20 or more natural teeth, the rate of chewing difficulty, and the rate of oral health check-up of elderly. The number of remaining natural teeth increased from 15.6 in 2010 to 17.1 in 2015, and the rate of 20 or more natural teeth also increased from 45.8% in 2010 to 53.7% in 2015. The rate of chewing difficulty was similar but declined a little from 44.3% in 2010 to 42.9% in 2017. Finally, the rate of oral health check-ups of the elderly increased significantly from 12.2% in 2010 to 21.1% in 2017.

Published: August 2024

This study was conducted to identify the subjective damage caused by COVID-19 and its related factors. The study subjects were members of the Korean Dental Association (KDA). We investigated the damage to dental clinics and hospitals caused by COVID-19 between January and April 2020. After analyzing the final 3,189 responses, the rate of decrease in patients was the highest at 34.9% in March, and the rate of decrease in income was the highest at 34.0% in April. As a result of the multilevel analysis, the damage caused by COVID-19 was greater in regions with more confirmed patients, more careers, and fewer dental staff. The government should establish a compensation plan for hospitals and clinics to prevent the collapse of the medical system due to the prolonged COVID-19. In addition, support for dentistry should be provided to maintain the oral health care system in the future.

Objectives: The aim of this study was to evaluate the efficacy of CK files as an ultrasonic instrument, and to determine most efficient file size for smear layer removal. Materials and Methods: Thirty-six extracted human mandibular premolars with single, straight root canals and mature apices were mechanically prepared and randomly divided into three groups. Group 1 (Control) underwent conventional needle irrigation, Group 2 (CKS) underwent passive ultrasonic irrigation with a #20 CK file, and Group 3 (CKL) underwent passive ultrasonic irrigation with a #30 CK file. After preparation and irrigation, all teeth were dried and split with a chisel to obtain the mesial and distal half of their roots. Each sample was evaluated using a scanning electron microscope, and data were analyzed using the Kruskal-Wallis and Mann-Whitney rank sum tests (p<0.05). Results: The CKS group showed less debris in the apical third than the other groups (p<0.05). In this section, no significant difference was observed among the other groups. And, there was no significant difference among any groups for the middle third section. Conclusion: This study showed that PUI with #20 CK file removed more smear layer compared to using #30 CK file at the apical third of the root canal.
Recent Trend of Esthetic All-Ceramic Materials and Guidelines for Correct Cementation
Authors: Park Yeong-Joon
Published: August 2024

Recently, there are much improvement in optical and mechanical properties of dental ceramic materials coupled with improved fabrication techniques, which have caused a considerable shift in the preference of the dentists to ceramic restorations. Because the chemical composition and microstructure of all-ceramic materials are different by the type, correct choice of cement type and surface treatment procedure, and cementation strategy is essential for the success of ceramic restorations with adequate retention and decreased incidence of complications. This manuscript reviews on the most often prescribed and some newly developed ceramic materials, and the selection criteria and usage guidelines of cement materials that are used in conjunction with various ceramic materials. This manuscript emphasizes that continuous updating the information of newly developed ceramic and cement materials and application techniques by the dentists and dental staffs are demanding in response to the constantly improving ceramic and cement materials and corresponding application protocol changes.
Occlusal consideration of edentulous patients
Authors: Paek Janghyun
Published: August 2024

Occasionally, complete dentures constructed in accord with the best clinical and laboratory procedures fail to serve successfully. These failures probably result from present ignorance of the occlusion and functions of living tissues. Nonetheless, in each case, the whole treatment procedure, both clinical and laboratory, must be reexamined in order to ascertain the point of failure. One can employ a technique more intelligently, and often improve on it, if the reasons for its use are known. When one is guided only by a recipe, the outcome will be doubtful whenever conditions are not the same as in the recipe. In this manuscript, occlusal consideration of edentulous patients will be discussed thoroughly.
The effects of nasal breathing due to pediatric allergic rhinitis on dentofacial growth and its dental considerations
Authors: Ong Seung-Hwan , Yoo Seung-Hoon
Published: August 2024

Allergic rhinitis is a specific IgE mediated inflammatory disease of the nasal mucosa, characterized by symptoms such as rhinorrhea, nasal congestion, nasal obstruction, nasal and eye itching, and sneezing. The prevalence of allergic rhinitis varies according to country, age, and surveying methods, but it seems to increase worldwide, also in Korea. Prolonged mouth breathing caused by allergic rhinitis can produce muscular and postural alterations, causing alterations on the morphology, position, growth direction of the jaws, and malocclusion. Also, mouth breathing leads to dryness of the mouth, causing various oral diseases; gingivitis, halitosis, inflammation of tonsil, increased risk of dental caries and dental erosion. In dental clinic, using rapid maxillary expansion to persistent allergic rhinitis patients with narrow maxilla can enlarge maxillary dental arch and nasal cavity anatomy, improving nasal breathing and reducing nasal cavity resistance. However, it is desirable to use along with otolaryngologic treatment. Dentists should be aware of the characteristics of allergic rhinitis and its effects on patients, and consider when planning dental treatment.

Authors: Gil Soo-Min , Park Jae-Sung , Kim Sang-Cheol
Published: August 2024

The aim of this study was to analyze the association between sella turcica bridging (STB) and palatally impacted canine and to investigate the correlation between the angular measurements of palatally impacted canine and STB using cone beam computed tomography (CBCT). The impaction group included 36 subjects (16.97 ± 6.00 years) who had at least one palatally impacted canine and the control group consisted of 36 subjects (16.89 ± 3.52 years) who had normally erupted canines without any dental anomalies. Sella turcica and dental measurements were obtained from reconstructed CBCT images using OnDemand3D 1.0software.Sella turcica dimensions were compared between two groups, and the STB ratio, the proportion of interclinoid distance to diameter of sella turcica, were compared between the impacted and non-impacted sides. Correlation coefficients were cal-culated between the angular measurements of palatally impacted canine and STB ratio.In the impaction group, interclinoid distance and STB ratio were significantly smaller than those of the control group (p < 0.001). The distribution of STB type II, partial calcification of intercliniod ligaments, was significantly higher in the impac-tion group than in the control group (p < 0.05). However, there was no significant difference of STB between the impacted and non-impacted sides (p > 0.05) in the unilateral impaction group. Further, STB ratio was negatively correlated with the mesiodistal angulation and the buccolingual inclination of the palatally impacted canine (p < 0.05). The STB was more frequently found in patients with palatally impacted canine, and the degree of STB was significantly associated with the angular measurements of impacted canine.
The use of implant assisted removable partial denture in a partially edentulous patient with a few unilateral remaining teeth and reduced interarch distance: A case report
Authors: Kim Jae-Hyun , Cho Hye-Won
Published: August 2024

Implant-assisted removable partial dentures (IARPD) provide additional retention and stability by placing a small number of implants in the strategic positions. Since the two implants can be covered by National Health Insurance Services, the treatment modality using IARPD has been increased to restore partially edentulous patients with a few unilateral remaining teeth and improved the clinical effectiveness and patient satisfaction. The patient with two anterior unilateral remaining teeth showed a problem of frequent fracture of artificial teeth and denture base with maxillary Kennedy Class I RPD due to wear of mandibular anterior teeth and loss of occlusal vertical dimension. This case report suggested that the incorporation of a limited number of implants into IARPD could improve the function and patient satisfaction for the partially edentulous patients.

Published: August 2024

It becomes a dilemma when Muslim communities cannot apply Islamic criminal law. In fact, a law is not only to be understood but also believed to be true by Muslims themselves. So, it is appropriate that the punishment for adultery is less likely to have a deterrent effect on the perpetrator. This is because, apart from conventional criminal law being poorly understood by the Muslim community, the sanctions are also quite light so that the deterrent effect desired by law enforcers cannot be realized. This research aims to analyze adultery law by applying linguistic approaches and ushul fiqh to adultery law. This type of research is normative law using a language and ushul fiqh approach. The data sources were primary and secondary, while data collection techniques were observation and literature study. The results of this research show that adultery is analyzed using a language and ushul fiqh approach is the perpetrator of a criminal act who deliberately commits the elements of inserting male genitalia into female genitalia (in intercourse), which is unlawful according to the substance of the act, not because subḥāt and women bring lust. The punishment for adultery is to jilīd one hundred times. This penalty can be applied if the legal action has been legal before the court by presenting four witnesses. The stipulated punishment cannot be changed with other types of punishment because the punishment is regulated by the text of the Al-Quran.
Numerical investigation of box shape effects on soil direct shear test
Authors: Hajivand Dastgerdi Rashid , Khan Arif , Kazemi Kamran , Kowalski Michal , Malinowska Agnieszka
Published: August 2024

The direct shear test is a fundamental method in geotechnical engineering that provides crucial soil shear strength parameters, including cohesion (c) and the angle of internal friction (ϕ). These parameters play a pivotal role in structural design, slope stability assessment, and soil stability evaluation. However, achieving a uniform normal stress distribution within the shear box remains a challenging task, which can result in inaccuracies in test results. This study investigates the impact of shear box shape, specifically comparing circular and square configurations, on the outcomes of the direct shear test. The findings reveal that the choice of lower or upper box movement has a minimal effect on test results. Moreover, circular boxes demonstrate superior normal stress distribution, leading to reduced variations in comparison to square boxes. Wall friction effects lead to lower shear capacity measurements, with circular boxes yielding higher shear levels when contrasted with square boxes. Additionally, the soil along the sides and corners of the specimen experiences diminished shear stress due to reduced normal stress. This research contributes significantly to our comprehension of how shear box shape influences the determination of shear strength parameters in direct shear tests, ultimately enhancing the reliability of geotechnical engineering assessments.

The RME model combined with the stemmatics method is a solution to students' low ability to understand concepts in multiplication. The research method used is an experiment with a quasi-experimental design. The population chosen was elementary schools in North Sumedang District which were randomly selected with 30 students for control an experimental classes. The research location is North Sumedang District, Sumedang Regency. The research instrument is a test in the form of pretest-posttest questions. The data analysis techniques used are validity test, homogeneity test, normality test, hypothesis test, mean difference test (Wilcoxon dan Mann Whitney test), and N-Gain test. The N-Gain test shows that learning in the experimental class has a positive influence as evidenced by an increase in learning outcome of 0.64. Apart from that, learning in the experimental class was better, as evidenced by the control and experimental classes, namely 64.07 and 84.03. This proves that learning in the experimental class where RME learning was applied using the stemmatics method was better than learning in the control class where conventional learning was applied. This increase is also influenced by the use of candy cane media with colorful appearance which can increase students' attention and enthusiasm when learning takes place.

Published: August 2024

Introduction

Il existe une relation complexe entre le statut résidentiel et la consommation de substances. En effet, la consommation de substances réduit les perspectives de logement et le fait d’être sans logement augmente les raisons de consommer des substances ainsi que les risques et la stigmatisation qui y sont associés.

Méthodologie

Dans cette analyse descriptive des personnes sans logement qui ont perdu la vie en raison d’une intoxication aiguë accidentelle liée à une substance au Canada, nous avons utilisé les données relatives aux enquêtes sur les décès tirées d’une étude nationale d’examen des dossiers concernant les décès par intoxication aiguë due à une substance en 2016 et 2017, afin de comparer les facteurs sociodémographiques, les antécédents médicaux, les circonstances du décès et les substances ayant contribué au décès des personnes sans logement et des personnes non identifiées comme sans logement, au moyen du test du khi carré de Pearson. Nous avons comparé le profil démographique des personnes décédées d’une intoxication aiguë aux données du Dénombrement ponctuel coordonné de l’itinérance dans les collectivités canadiennes de 2016 et du Recensement de 2016.

Résultats

Les personnes sans logement étaient nettement surreprésentées parmi les personnes décédées d’une intoxication aiguë en 2016 et 2017 (8,9 % contre moins de 1 % de la population générale). L’intoxication aiguë ayant entraîné le décès des personnes sans logement a eu lieu plus souvent à l’extérieur (24 %); un opioïde ou un stimulant a plus fréquemment contribué à leur décès (68 % à 82 %; les deux substances ont été responsables de 59 % des décès) et ces personnes avaient plus souvent été libérées d’un établissement correctionnel ou été autorisées à sortir d’un établissement de soins de santé au cours du mois précédant leur décès (7 %).

Conclusion

Nous présentons plusieurs possibilités de réduire les décès attribuables à une intoxication aiguë chez les personnes sans logement, notamment lors de la prise de contact avec les services de santé et d’autres établissements, par des mesures de soutien à la réduction des méfaits liés à la consommation d’opioïdes et de stimulants ainsi que par la création d’environnements plus sûrs pour les personnes sans logement.

Authors: Воронков Александр
Published: August 2024

Результаты этимологических исследований позволяют заключить, что происхождение ряда субстратных топонимов Южного Урала связано с ранним праиндоарийским (дардо-индоарийским) языком. Моделирование исторических процессов позволяет установить хронологическую связь этих топонимов с абашевской и синташтинской культурами среднего бронзового века. Сокращённый вариант текста, в который не вошли многие данные, был представлен в виде доклада на II Международной конференции "Древние и традиционные культуры во взаимодействии со средой обитания: проблемы исторической реконструкции", Челябинск, 12-14 апреля 2023.

Published: August 2024

У контексті високих вимог до швидкісних та силових якостей гандболісток знання про анаеробні процеси дозволяє розробляти цілеспрямовані тренувальні програми, що спрямовані на максимальне використання енергетичних ресурсів спортсменок, що є ключовим для успіху в інтенсивних ігрових моментах. Актуальність дослідження полягає в недостатньому вивченні специфіки жіночого гандболу, особливо в контексті анаеробних здібностей і механізмів енергозабезпечення. Мета дослідження – визначити рівень анаеробної працездатності й анаеробного лактатного механізму енергозабезпечення організму кваліфікованих гандболісток. Методи дослідження: теоретичний аналіз і узагальнення науково-методичних джерел, педагогічні спостереження, метод визначення показників анаеробної працездатності та рівня потужності анаеробного лактатного механізму енергозабезпечення організму спортсменок за допомогою комп’ютерної програми «AnaerobHandball», методи математичної статистики. За результатами тестування на анаеробну працездатність визначено, що середні показники в обох групах мають незначні відмінності, що свідчить про однаковий початковий рівень підготовленості. Потужність анаеробного лактатного механізму енергозабезпечення в гандболісток на констатувальному етапі визначена як середня, що підкреслює можливість для подальшого розвитку та вдосконалення через цілеспрямовані тренувальні впливи. Зіставлення результатів між групами не виявило статистично значущих відмінностей, що вказало на однаковий рівень анаеробної працездатності та потужності анаеробного механізму між групами на початку дослідження. Отримані результати дозволяють закласти фундамент для подальшого вивчення та оптимізації тренувальних процесів, спрямованих на підвищення анаеробної працездатності та вдосконалення анаеробних енергетичних процесів серед жіночих гандбольних команд. Дослідження підтвердило, що систематичне застосування спеціалізованих методик тренувань може істотно покращити ці показники у спортсменок, що у свою чергу сприятиме підвищенню їх спортивної ефективності та витривалості під час змагань. Зокрема, виявлено, що рівень анаеробної працездатності та потужність анаеробного лактатного механізму енергозабезпечення мають значний вплив на здатність гандболісток виконувати високоінтенсивні дії протягом гри. Вказано на необхідності подальшого вивчення цієї теми з метою оптимізації тренувальних програм і методик відновлення. Запропоновані напрями подальших досліджень включають аналіз впливу різних тренувальних підходів на анаеробну працездатність і розроблення індивідуальних програм, що враховують особливості кожної гандболістки.
ДИНАМІКА ПОКАЗНИКІВ МОВЛЕННЄВОГО РОЗВИТКУ ТА ФІЗИЧНОЇ ПІДГОТОВЛЕНОСТІ ДІТЕЙ СТАРШОГО ДОШКІЛЬНОГО ВІКУ В ОСВІТНЬОМУ ПРОЦЕСІ ЗДО

Питання адаптації та соціалізації дошкільнят із порушенням мовленнєвого розвитку в освітньому процесі закладів дошкільної освіти (ЗДО) має неабияке значення, адже однією з найпоширеніших проблем серед цієї вікової категорії є порушення мовленнєвого розвитку. Доведено, що фізичне виховання сприяє покращенню мовлення, зміцненню здоров’я та адаптації дітей в соціумі. Результатами експерименту підтверджено той факт, що адаптивне фізичне виховання є ефективним засобом та невід’ємною частиною освітнього процесу дітей, які мають порушення мовлення. Мета дослідження – визначити динаміку показників фізичної підготовленості дітей 5–6 років з порушенням мовленнєвого розвитку в процесі занять з адаптивного фізичного виховання в ЗДО. Реалізація поставленої мети передбачала використання таких взаємодоповнювальних методів дослідження, як: теоретичний аналіз і узагальнення даних науково-методичної літератури та мережі Інтернет, педагогічні методи дослідження, методи математичної статистики. Дослідження проводилось у ЗДО № 652 та № 270 комбінованого типу Дарницького району м. Києва з вересня 2023 року до квітня 2024 року. До участі було залучено 44 дитини віком 5–6 років з порушенням мовленнєвого розвитку, з яких 32 хлопчиків та 12 дівчаток. У процесі дослідження було здійснено діагностику мовленнєвого розвитку (номінативної функції мовлення та розуміння складних логіко-граматичних конструкцій) та оцінено фізичну підготовленість дітей 5–6 років з порушенням мовленнєвого розвитку. Кількість хлопчиків, які в процесі називання предмету за картинкою спотворюють звуко-складову структуру слова, зменшилась на 9,3%. Кількість дівчаток, які в процесі виконання завдання здійснювали пошук зі знаходженням правильного найменування, збільшився на 8%. Кількість дітей, яким притаманне точне розуміння складних логіко-граматичних конструкцій, збільшилась на 3,1%, перепитування і помилки допускають на 3,1% дітей більше. Відсоток дівчаток, яким притаманний тривалий пошук зі знаходженням правильної картинки, зменшився на 17%, натомість збільшилась кількість дівчаток, які перепитують і допускають помилки. Позитивну динаміку відзначено у фізичній підготовленості хлопчиків та дівчаток 5–6 років з порушенням мовленнєвого розвитку протягом експерименту в закладах дошкільної освіти. Результати дослідження свідчать про ефективність застосування засобів адаптивного фізичного виховання в освітньому процесі ЗДО дітей старшого дошкільного віку з порушенням мовлення.

Сучасний етап розвитку шкільної освіти Китайської Народної Республіки характеризується як період освітніх змін, ключовим елементом якого є впровадження освітньої реформи. Останнім часом моделі навчання вчителів зазнали різних змін, еволюціонуючи від добре відомих і вкорінених традиційних підходів до компетентніших підходів. Модель навчання, заснована на компетенціях, є новою системою відліку, якою заклади вищої освіти керуються в розробленні своїх програм. Навчання компетентності пов’язане з типом ефективних дій, орієнтованих на вирішення проблем та покращення соціального контексту, застосування знань та ефективне використання ресурсів. Актуальність такого кола питань зумовлена тим, що професійна підготовка вчителя фізичного виховання являє собою процес становлення його особистості, розвитку загальної та професійної педагогічної культури й компетентності, формування професійних компетенцій, що виступають передумовою ефективної майбутньої професійної діяльності та є вкрай важливим для підготовки, виховання, становлення молодого покоління. Мета статті – охарактеризувати роль інформаційно-цифрових технологій у практичній діяльності вчителів фізичного виховання Китаю. Методи дослідження – теоретичний аналіз і узагальнення даних літературних джерел, соціологічні методи дослідження (анкета «Профіль шкільного здоров’я: анкета вчителя фізичного виховання (School health profiles lead physical education teacher questionnaire)», методи математичної статистики. Було проведено аналіз компетентностей учителів фізичної культури щодо інформаційно-цифрових технологій у процесі фізичного виховання. Професійна компетентність учителя проявляється в сукупності фахових знань, умінь і навичок, які відображають теоретичну, практичну і методичну підготовленість, здатність до їх творчої реалізації в різних соціальних ситуаціях практичної діяльності у сфері фізичного виховання. Також було з’ясовано, що освітня політика КНР щодо формування цифрової компетентності є досить прогресивною, про що свідчить низка проведених заходів і прийняття нормативних документів, які підкреслюють необхідність розвитку зазначеної компетентності в громадян, зокрема освітян.
