Extended Validation of the Korean Version of the Quality of Life Survey

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.     

The carbon footprint of active sport participants

Researchers examining carbon dioxide-equivalent emissions (carbon footprint) in sport have focused on sport events and, to a lesser extent, sport teams, but provided only average or aggregate values. The author takes the perspective of active sport participants and considers the heterogeneity of individual sport participation behavior. Using online surveys, adult active sport participants (n = 6537) in 20 different sports with main residence in Germany were asked to report their sport-travel behavior in 2015, including traveling in the context of regular (weekly) activity, sport competitions/tournaments, league games, day trips, and training camps/vacations. Annual carbon footprints were estimated using information about travel distances and transportation means. The results revealed an average annual carbon footprint of 844 kg of carbon dioxide-equivalent emissions, with individual sports producing more emissions than team/racket sports. Participants in nature sports had the highest emission levels. Regression analyses revealed that environmental consciousness significantly reduced carbon footprint in individual sports, but not in team/racket and nature sports, supporting the existence of an environmental value-action gap. Activity years, club membership, weekly exercise hours, performance level, and income were mainly positively associated with annual carbon footprint, while gender was insignificant. The findings have implications for policy makers and managers in sport associations and clubs.     

Sport as medicine: How F3 is building healthier men and communities

Given sport has been largely absent from U.S. public health policies and discourse, the author suggests ways that sport can be better managed to promote health. Using a critical perspective and grounded theory approach, the author examined the experiences of 14 men in the grassroots recreational program, F3. Data were collected through observation and semi-structured interviews. Based on the results, a conceptual model that suggests how sport should be managed to address illnesses related to physical inactivity is put forth. The resulting Sport as Medicine model indicates that Creating a Team Structure, Providing a Place to Be Accountable, and Ensuring No One is Left Out, led to meaningful Health Outcomes, including Physical Health, Mental Toughness, and Social Connections. As the distinctiveness of sport continues to emerge, the author provides a framework to consider how sport can be part of public health efforts to address physical inactivity. Thus, this work positions sport as medicine by pinpointing how sport can be managed so that holistic health outcomes are more likely achieved.     

The effectiveness of a 17-week lifestyle intervention on health behaviors among airline pilots during COVID-19

PurposeThe aim of this study was to evaluate the efficacy of a 17-week, 3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019 (COVID-19) pandemic.MethodsA parallel-group (intervention and control) study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic. The intervention group (n = 38) received a personalized sleep, dietary, and physical activity (PA) program. The control group (n = 41) received no intervention. Outcome measures for sleep, fruit and vegetable intake, PA, and subjective health were measured though an online survey before and after the 17-week period. The changes in outcome measures were used to determine the efficacy of the intervention.ResultsSignificant main effects for time × group were found for International Physical Activity Questionnaire-walk (p = 0.02) and for all other outcome measures (p < 0.01). The intervention group significantly improved in sleep duration (p < 0.01; d = 1.35), Pittsburgh Sleep Quality Index score (p < 0.01; d = 1.14), moderate-to-vigorous PA (p < 0.01; d = 1.44), fruit and vegetable intake (p < 0.01; d = 2.09), Short Form 12v2 physical score (p < 0.01; d = 1.52), and Short Form 12v2 mental score (p < 0.01; d = 2.09). The control group showed significant negative change for sleep duration, Pittsburgh Sleep Quality Index score, and Short Form 12v2 mental score (p < 0.01).ConclusionResults provide preliminary evidence that a 3-component healthy sleep, eating, and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic.

实践性知识:教师专业发展的知识基础

教师在从事日常教育教学工作中自身如何发展 ?教师的专业发展具有什么知识基础 ?为什么教师学了教育学、心理学 ,还是不会教书 ?教师如何提高自我专业发展的意识和能力 ?———这些问题是本文探讨的焦点。文章从教师的知识构成入手 ,将教师的知识分成“理论性知识”和“实践性知识” ,然后对教师实践性知识的定义、内容、状态和形成机制进行分析 ,并强调了“教师实践性知识”这一概念的赋权意义和专业建设意义。

寒春过后看世界“变暖说”

本文针对目前的热点话题——全球气候变暖,提出了三个疑问：气候真的在异常变暖吗？气候变暖真的有害吗？即便气候真的在异常变暖,主要是人为排放温室气体所致吗？经论证分析,本文认为气候变化是一个还没有定论的科学前沿问题,和政治、经济有关,但应该和公众无关。

葱内生真菌抑菌活性初探

目的：从葱的根、茎、叶中分离内生真菌,并进行初步抗菌活性检测,得到具有高抗菌活性的菌株。方法：1．用PDA培养基分离葱的内生真菌;2．用查氏培养基进行发酵实验。3．进行滤纸片抑菌实验。结果：从葱中分离出的17株内生真菌,均具有抗菌活性,其中,抑菌圈直径大于1．0cm的高抗菌性菌株有11株,占总分离菌株数的64．71％。结论：葱内生真菌具有类似宿主植物葱一样的广泛抗菌性（分离得到的17株内生真菌均具有抗菌性）,但由于宿主植物本身所具有的强抗菌性,使分离得到的菌株种属多样性较少。
