The purpose of this study is to derive implications for establishing vocational training education policies in Korea by investigating COVID-19 countermeasures in the United States, Germany, Switzerland, Australia, the United Kingdom, and Singapore, which are representative vocational education training countries. The implications derived from the survey of leading countries in vocational education training are as follows. First, in order to respond to COVID-19, face-to-face vocational education training was quickly converted to online education. Second, the system was strengthened to overcome the crisis of the apprenticeship system, especially the British and Australian governments established a special budget for the apprenticeship system. Third, due to COVID-19, blended learning has become a new standard education model, accelerating the digitalization of vocational education training. Finally, leading countries in vocational education training are promoting the development of the edutech industry to support online education. This provides important implications for the direction of change in vocational education training in South Korea.

PURPOSE: This study examined the effects of various interventions for improving the hip joint range of motion on elite badminton players, including body balance ability, jumping power, smash speed, and joint range of motion. METHODS: The study was conducted on elite badminton players belonging to the S badminton team in Yongin, Gyeonggi-do, and the M badminton team in Suwon, Gyeonggi-do. Twenty-one elite badminton players were selected; they were assigned randomly to Experimental Group 1 (n = 11) and Experimental Group 2 (n = 10). Before and after the intervention, the hip joint range of motion, modified star excursion balance test, Sargent jump, and smash speed were measured. In Experimental Group 1, hip joint manual mobilization was applied by a physical therapist, and hip self-exercise performed by the athletes was applied in Experimental Group 2. This intervention was applied once a day, three times a week, for four weeks. RESULTS: A significant increase in the hip joint range of motion (flexion and extension) and modified star excursion balance test (posteromedial direction) was observed in Experimental Group 1 (hip joint mobilization applied group) compared to Experimental Group 2 (hip joint self-exercise applied group) (p < .05). CONCLUSION: When elite level badminton players require improvement in hip flexion and extension range of motion and posteromedial body balance, hip joint mobilization is more effective than hip self-exercise application.

Background: Dental evaluation and protection are important for preventing traumatic dental injuries when patients are under general anesthesia. The objective of the present study was to develop a questionnaire based on dentition-related risk factors that could serve as a valuable tool for dental evaluation and documentation. Methods: We developed a questionnaire for dental evaluation before administration of general anesthesia, investigated the association between patient-and-dentist responses and mouthguard fabrication, and assessed response agreement between 100 patients. Results: Protective mouthguards were fabricated for 27 patients who were identified as having a high risk of dental injury. There was a strong association between dentists' responses and mouthguard fabrication, depending on the general oral health status, use of ceramic prosthesis, presence of masticatory pain related to periodontal diseases, gingival edema, and implants (P < 0.05). Response agreement between patients and dentists for items related to dental pain, loss of dental pulp vitality, root canal therapy, dental trauma, aesthetic prosthesis, tooth mobility, and implant prosthesis was high (Cohen's kappa coefficient κ ≥ 0.6). Conclusions: A high agreement was observed between patient-dentist responses and a strong association with mouthguard fabrication for items pertaining to ceramic prosthesis, masticatory pain, and dental implants. Patients with a "yes" response to these items are recommended to undergo a dental evaluation and use a dental protective device while under general anesthesia.

This study investigates the effect of recovery elasticity of beauty college students on university life adaptation during COVID-19. Further, the mediating effect of grit in relation to recovery elasticity and university life adaptation is analyzed. Survey data of 223 students (female: 192; male: 31) were collected for multiple and intermediate regression analyses using SPSS 24.0. The results reveal a static correlation between the lower factors of resilience, glittery, and adaptation to college life and that the resilience of junior college students in the beauty department had a static effect on grit and their adaptation to college life. Passion, a subordinate factor of grit, is mediated by the effect of grit on the relationship between resilience and adaptation to university life. However, perseverance, another subordinate factor of grit, did not have any such mediating effect. These results confirm the importance of grit, particularly passion, for resilience and adaptation to college life. It was confirmed that resilience was due to college life adaptation of beauty department students, and it was confirmed that passion, a sub-factor of grit, also had a mediating effect. Therefore, it is judged that resilience induces physical and mental adaptation, interpersonal adaptation, and academic adaptation necessary for college life, and works in many ways to improve the quality of life of beauty department junior college students. Instructors should consider developing educational programs for improving recovery elasticity and grit to help students better adapt to university life.

Background: The surgical threshold for bicuspid aortic valve (BAV)-related aortopathy is a matter of debate due to its uncertain etiology and prognosis. This study investigated the prognosis of unrepaired BAV aortopathy in patients undergoing surgical aortic valve replacement (SAVR). Methods: We retrospectively analyzed data from 720 patients (age, 60.8±11.5 years; 246 women) who underwent SAVR for BAV disease without aortic repair between 2005 and 2020 at Asan Medical Center. The clinical endpoints were defined as occurrences of sudden death, aortic dissection or rupture, and elective aortic repair. To estimate postoperative changes in the dimensions of the unrepaired aorta, the individual annual aortic expansion rate was calculated. Multiple linear regression models were used to evaluate the risk of aortic expansion. Results: The mean ascending aortic diameter was 39.5±4.6 mm, and 299 patients (41.5%) had a baseline ascending aorta diameter >40 mm. During 70.0±68.3 months of follow-up, the mean annual aortic expansion rate was 0.39±1.96 mm/yr, no aortic dissection or rupture was observed, and sudden deaths were reported in 12 patients (0.34% per person-year). Linear regression analysis revealed no significant correlation between the baseline ascending aortic diameter and postoperative aortic expansion (R²=0.004, β=-0.84, p=0.082). Conclusion: In selected patients undergoing SAVR for a BAV (<55 mm), the risk of adverse aortic events was very low. As this observation contradicts current practice guidelines advocating for proactive aortic replacement in dilated ascending aortas measuring >45 mm, the study results need further validation by studies involving larger populations or randomized controlled trials.

Research misconduct has been a strong societal concern in sport and leisure studies. However, little is known about the complex mechanisms and ways of promoting research integrity. This study aimed at exploring the ways in which research integrity in sport and leisure studies could be established from the perspectives of academia. Employing a grounded theory approach, 13 academics and graduate students were invited to the study. Data were collected primarily through focus group and one-on-one follow-up interviews. Perceived negative factors contributing to research misconduct within socio-political/socio-environmental, socio-cultural, and personal contexts were identified. Three approaches, (a) top-down approach, (b) bottom-up approach, and (c) continuous education, as well as subsequent practical strategies were also suggested for the enhancement of research integrity within the field. This paper provided empirical knowledge regarding barriers to and opportunities for improving research integrity in sport and leisure studies.

최근(2014~2017년) 강수량은 평년대비 71% 수준으로 2017년에는 누적된 강우부족으로 극심한 가뭄피해가 발생하였다. 용인시 또한 최근의 3년(2014~2017년)의 경우 연속으로 100년 빈도에 해당하는 가뭄이 발생하는 등 심각한 가뭄이 발생 되었으며, 하절기를 제외한 기간의 경우 평년에 가까운 강수가 발생하나, 하절기에는 강수가 매우 작아 심각한 가뭄이 발생하는 경향으로 조사되었다. 용인시가 관리하는 소규모 농경지는 대형농업용 수원공이 없어 작은 가뭄에도 쉽게 피해가 발생되고, 저수지, 취입보, 양수장 등 수원공이 설치되어 있으나 내한능력 부족 및 영농방식 변화 등으로 상습적으로 가뭄 피해를 입고 있다. 또한, 관리 농경지 및 농업 수리시설물에 대한 현황조사 미비로 상세한 이력 관리가 되어 있지 않아 시설물의 유지관리 및 중장기 계획 수립이 어려운 실정으로 수리시설물에 대한 이력조사가 요구되며, 전체 용수 수요량의 60% 이상에 해당하는 농업용수의 체계적인 조사를 실시하여 항구적 가뭄극복을 하기 위한 가뭄분석을 하였다. 본 연구에서는 농경지에 대하여 관개계획 기준치를 보통 10년 빈도의 가뭄에 극복이 가능하도록 설정하므로, 계획빈도의 가뭄에 안정적으로 농경지에 농업용수가 공급될 수 있도록 기설 수리시설물의 공급능력을 검토하여 확인하였다. 용인시 전역에 대하여 우선 기초자료로 기상 및 수문조사와 농촌용수관련인자를 조사하였으며, 상위 관련계획 조사로 농업·가뭄·수자원 관련계획을 조사하였다. 기존 저수지 농업용수 공급능력은 유역의 유입량은 DIROM모형을 사용하여 산정하고 관개구역의 필요수량은 Penman방법으로 증발산량을 산정하였다. DIROM 모형과 Penman방법으로 산정된 자료를 참고하여 기존 수원공 시설의 물수지 분석을하여 과정에 HOMWRS(수리시설모의조작시스템) 모형을 적용하여 농경지 필요용수량과 공급 가능량, 지하수 취수량의 능력검토를 하였으며, 가뭄 계획빈도 10년 조건에서 농업용수 공급능력을 검토한 결과 수리적으로 안전한 농경지는 전체 농경지 대비 64.18%로 확인되며, 향후 강우 전망 RCP6.0 시나리오에서 2021년~2040년에 5.1%정도 감소하는 것으로 전망된 것을 감안하면 향후 용인시 지역은 가뭄이 보다 심화될 것으로 판단되므로 시급히 구조적 대책이 가능한 여건의 지역에 한하여 수원공 시설을 확보하여 가뭄에 반드시 대비하여야 할 것으로 판단된다.
