중장년층과 노년층에 따른 구강관리용품 사용 여부가 현존 자연치아 수에 미치는 영향
박규빈 보건의료산업학회 2023 보건의료산업학회지 Vol.17 No.4
Objectives: This study used raw data from the National Health and Nutrition Examination Survey to determine the effect of oral care product use on the number of existing natural teeth among middle-aged and elderly people. Methods: A total of 4,208 people, comprising2,513 middle-aged and 1,695 elderly people, were surveyed using IBM SPSS for data analysis. Results: The more middle-aged and elderly people used dental floss and the less they used other oral aids, the greater the number of existing natural teeth they possessed. Among the elderly, the number of existing natural teeth increased with interdental brushes and electric toothbrushes. Conclusions: To increase the number of existing natural teeth, regular dental checkups and professional oral health education are necessary so that middle-aged and elder can select and use oral care products suited to their oral health status.
Variation in the functional compounds of molten salt Kimchi during fermentation
박규빈,김연미,김재한,박종태 충남대학교 농업과학연구소 2019 Korean Journal of Agricultural Science Vol.46 No.1
To produce a high-quality Kimchi product, molten salt was used for the Kimchi. Changes in the physiochemical properties and functional compounds were analyzed during fermentation. The salinity of bay salt Kimchi was higher than that of the molten salt Kimchi. The fermentation speed of the lactic acid bacteria in the molten salt Kimchi was significantly faster. To evaluate the effects of the salts on the changes in the functional compounds during fermentation, the antioxidant activity, total phenolic compounds (TPC), flavonols, phenolic acids, and glucosinolates in Chinese cabbage were analyzed. In the first 9 days, antioxidants were decreased during this fermentation period and then, increased after that. TPC was slightly increased for all the conditions after 40 days fermentation. Kaempferol was a major flavonol but had a relatively larger decrease in the molten salt Kimchi than in the bay salt samples. Phenolic acid did not show any significant difference among the samples. The glucosinolate contents were significantly decreased in all the conditions of Kimchi during the fermentation period. Consequently, the molten salt greatly affected the fermentation speed of Kimchi and the total characteristics of the Kimchi lactic acid bacteria. Although the functional compounds of Chinese cabbage were decreased during the fermentation of Kimchi, this decrease did not profoundly deteriorate the food quality. Therefore, high-quality Kimchi with enhanced bioactivity will be available if appropriate Chinese cabbages that have enhanced functional compounds are used.
컴퓨팅 사고력 향상을 위한 로봇 활용 수학 교수학습 자료 개발
박규빈,임해미 한국학교수학회 2023 韓國學校數學會論文集 Vol.26 No.3
This study aimed to develop teaching and learning materials that can improve computational thinking in the areas of high school functions and analysis by using robots. Through a literature review, we analyzed research on computational thinking and examined how computer programming and coding education are being conducted in domestic and international mathe- matics curricula. We then restructured the Carnegie Mellon University DBL Unit to propose a DBL Unit model that utilizes robots, and we developed mathematics teaching materials using LEGO Mindstorms EV3 for units in the areas of functions and analysis. Subsequently, based on the Delphi survey results, we revised the developed materials and provided recommendations for en- hancing computational thinking in mathematics classes.
중학교 축구선수들이 지각하는 지도자의 감성리더십과 자아존중감 및 운동지속의 인과적 관계
박규빈,정경구 한국코칭능력개발원 2020 코칭능력개발지 Vol.22 No.1
본 연구의 목적은 축구 지도자의 감성리더십이 축구선수들의 자아존중감 및 운동지속에 어떠한 영향으로 작용되는지에 대해 알아보고 축구선수가 경기 및 훈련 상황 그리고 선수생활 시 최상의 수행력을 발휘할 수 있도록 지도자의 리더십의 효율적인 적용을 위한기초자료로 활용하는데 목적이 있다. 이를 위해 2019년 대한축구협회에 선수 등록되어 있는 남자 중학교 축구선수를 유층집라무선표집 방법을 이용하여 269명을 추출하였다. 연구목적과 가설에 맞춰 SPSS/PC+ Version 25.0을 이용하여 빈도분석, 탐색적 요인분석과 신뢰도 분석(Cronbach's α), t검증, F검증, 다중회귀분석을 실시하여 연구의 결과를 도출하였다. 본 연구의 결과는 다음과 같다. 첫째, 감성리더십, 자아존중감, 운동지속은 상관관계가 있다. 둘째, 지도자의 감성리더십이 자아존중감에 미치는 영향에서는 하위요인 관계관리능력, 자기관리능력, 자기인식능력, 사회적 인식능력은 일반적 자아, 사회적 자아, 가정적 자아, 일반적 자아에 부분적으로 유의한 영향을 미치는 것으로 나타났다. 셋째, 지도자의 감성리더십이 운동지속에 미치는 영향에서는 하위요인 자기관리능력, 관계관리능력, 자기인식능력, 사회적인식능력이 통계적으로 유의한 영향을 미치는 것으로 나타났다.
