The purpose of this study was to investigate the effect of elderly women’s age and exercise on functional fitness, cognitive functions, and serum BDNF and to analyze the relationship among serum and other variables through a 10 week exercise program. For this study, 50 elderly women were divided into two groups, young-elderly (age 65-74; n=28), and old-elderly (age 75-84; n=22). Then, they participated in either an aerobic exercise program, or a combined exercise program performed in 60 minute sessions, three times a week for 10 weeks). All subjects underwent functional fitness tests, cognitive tests and BDNF tests before and after the 10 week experiment. Aerobic exercise was composed of basic steps and rhythmic movements. The intensity was set to 40-50% HRR and 11-12 RPE with gradual enhancement. Combined exercise was composed of basic steps and rhythmic movements, as well as resistance training using 1 kg dumbbells, with the intensity set to 40-50% HRR and 11-12 RPE, and 2 sets of 8-10 repetitions for the dumbbells, with gradual enhancement. For data analysis, mean and standard deviation scores were calculated, and t-test, two-way repeated ANOVA, and correlation analysis were used. The results of the study were as follows. First, upper and lower muscle strength, cardiovascular endurance, lower body flexibility, agility, and dynamic balance were improved after 10 weeks in both aerobic and combined exercise groups within the young-elderly (65-74) age group. Comparing the two groups, the combined exercise group’s upper and lower muscle strength was more improved than the aerobic group’s, but there was no significant increase in upper body flexibility. After the 10 week program, there were significant increases in lower muscle strength, flexibility, agility, and dynamic balance in both exercise groups within the old-elderly(75-84) age group. However, there were no significant changes in upper muscle strength, cardiovascular endurance, or lower body flexibility. Second, finger simple and choice reaction times, digit span, trail-making and MMSE-DS were improved after 10 weeks in both exercise groups within the young-elderly (65-74) age group. Comparing the two groups, the combined exercise group’s digit symbol substitution was more improved than the aerobic group’s after 10 weeks. Also, cognitive functions, which includes digit span, digit symbol substitution, trail-making, MMSE-DS were improved in both the aerobic and combined exercise groups within the old-elderly (75-84) age group. However, there was a significant improvement in choice reaction time with the aerobic exercise group after 10 weeks but there were no significant changes in simple reaction time. Third, serum BDNF was increased after 10 weeks in both the aerobic and combined exercise groups within both the young-elderly (65-74) and the old-elderly (75-84) age groups. Fourth, there were significant correlations between serum BDNF levels and cardiovascular endurance, upper body flexibility and simple reaction time. Analyzing the above data, aerobic and combined exercises improved women’s functional fitness, cognitive function and serum BDNF levels in both of age groups. Specifically, serum BDNF levels improved in both exercise groups within both age groups. Unfortunately, there was no significant difference in serum BDNF levels between the groups, although the rate of increase was higher among the combined exercise group within both age groups. Combined exercise programs can improve neurotrophic factor, which decreases with age and leads to neurological problems. In addition, the effect of exercise on cholinergic neuron activation increased inducing hippocampal BDNF expression, which helps protect against brain function loss. Appropriate physical activity is an essential method of maintaining cognitive function and physical fitness. There are a lack of programs adapted for the elderly, so various exercise programs are needed to improve the health of the elderly. In addition, recent studies are concentrating on serum BDNF levels and hippocampal BDNF expression but there is a lack of knowledge regarding how much brain BDNF flows into the blood. To get a more accurate picture, additional research is necessary.

This study aims to investigate how the exercise intensity and the Phytoncide in the air affect Brain-derived neurotrophic factor (BDNF), Insulin like growth factor-1 (IGF-1) and vascular endothelial growth factor (VEGF) of the neurotrophic factors of the middle-aged woman according to the inclination of ground and forest. Participants in the study were divided into 3 types of exercise program. Ⅰ Type group( ground, low level of Phytoncide); 60% HRR, Ⅱ Type group(low forest slope, high level of Phytoncide); 60% HRR, Ⅲ Type group(middle forest slope, general level of Phytoncide); 80% HRR were ordered to exercise for 110 minutes 3 times a week for 12 weeks. The blood samples of all the study participants were taken after having a grand rest both before and after 12-weeks exercise program and then the changes of neurotrophic factors were analyzed. After finding the mean and standard deviation, independent T-test and analysis of covariance (ANCOVA) were used to analyze the data and Scheffe as a post analysis was also conducted. The bottom line is as follows. First, BDNF in Ⅲ type group increased significantly comparing with both Ⅰ type and Ⅱ type group. However there were no significant difference between Ⅰ type and Ⅱ type group. Second, IGF-1 in Ⅱ type group increased significantly comparing with Ⅰ type and Ⅲ type group. However there were no significant difference between Ⅰ type and Ⅲ type group. Third, VEGF in Ⅱ type group increased significantly comparing with Ⅰ type and Ⅲ type group. Ⅰ type and Ⅲ type group decreased but there were no significant difference between Ⅰ type and Ⅲ type group. The Results described that the exercise program in middle slope under 80% HRR is effective on BDNF through the exercise program for 12 weeks according to the terrain and the exercise program in low slope with high level of Phytoncide under HRR 60% were effective on both IGF-1 and VEGF which are important growth factors in angiogenesis. Therefore, it is determined that neurotrophic factor is influenced by the exercise according to the forest gradient and phytoncide. Further more, even though there is not high forest slope walking exercise in moderate forest gradient and the environment phytoncide can improve cognitive function enhancing neurotrophic factor in blood of ordinary person.

Physical activity in the forest environment stimulates the parasympathetic nervous system of humans and has a positive effect on the autonomic nervous system and on mood and emotion. However, there are no studies on the benefits of exercise through the forest environment for patients with myocardial infarction. The aim of this study was to investigate the effects of single session walking on the physiological and psychological state of the forest environment and the urban environment for 15 minutes in myocardial infarction patients. The heart rate variability(HRV) was measured in 10 patients with myocardial infarction to assess physiological state after single session walking for 15 minutes in forest environment and urban environment. In order to evaluate the psychological state, a profile of mood scale(POMS) and semantic differential(SD) questionnaire were used. After finding the mean and standard deviation, Wilcoxon signed rank test was used to analyze the data. The conclusion was as follows. First, the autonomic nervous system was stabilized after a single session walk of 15 minutes in the forest environment changed positively the heart rate variability of patients with myocardial infarction rather than from a single session walk of 15 minutes in the urban environment. Second, the mood conditions was improved after a single session walk of 15 minutes in the forest environment changed positively the anger-hostility, confusion, depression, tension-anxiety, total mood disturbance of patients with myocardial infarction rather than from a single session walk of 15 minutes in the urban environment. Third, after a single session walk of 15 minutes in the forest environment, the comfort, natural, and calm of patients with myocardial infarction were significantly improved compared to a single session walk of 15 minutes in the urban environment, improving their mood and emotional state. Therefore, this study suggests that even a single session walk of 15 minutes through the forest environment could have a positive impact on the physiological and psychological state of patients with myocardial infarction and, in turn, on health care.

The purpose of the study was to provide basic information for physical education teaching and excercise programing through Model Verification and Analysis of Relationship of how exercise self-schema level of adolescents affects their physical activity level, physical self-efficacy and stress. To achieve the study purpose, the subjects were selected as male and female students attending middle schools and high schools located in C city, first, for 200 students to explore the construct of exercise self-schema scale and for 20 students from middle and high schools to have an interview. Then, the first and the second preliminary surveys on physical self-efficacy of adolescents were conducted with 120 middle and high school students respectively. To verify reliability and validity on physical activity level and physical self-efficacy of adolescents, a preliminary survey was conducted with 134 students and the first and second ones were administered to a total of 906 students(463 from middle school, 443 from high school) on a 7 week basis respectively for the final scale. The tools for measuring physical self-efficacy of adolescents include: Physical Activity Questionnaire of Korean Adolescents(Hong Seung Yeon, 2006), Physical Self-efficacy Questionnaire(Seok Chang Hyuck, 2013), and Stress Questionnaire(Lee Kyung Sook, 2009), which were used by adapting and reconstructing. To analyze the study result, frequency analysis, independent sample t-test, and stepwise multiple regression were carried out using SPSS(ver, 23.0), and confirmatory factor analysis and structural equation model analysis were carried out using AMOS(ver, 23.0). Based on the research process and analysis results, the conclusions were as follows. The results of differences among exercise self-schema of adolescents, their physical activity, physical self-efficacy and stress based on the general characteristics revealed the following: First, male students showed higher levels of exercise self-schema in the behavioral-cognitive and affective factors than female students, middle school students in the behavioral-cognitive factor and high school students in the affective factor. Second, regarding physical activity level during the day time, male students showed higher levels than female students while female students spent more time sitting during the day than male students. More male students participated in day time walking than female students. Middle school students showed higher levels of day time physical activity and walking while middle school students showed more hours of sitting. Third, female students showed higher levels of physical self-efficacy in running, exercise participation, muscle strength, appearance, and body shape than male students; high school students showed higher levels in running, muscle strength, appearance, and body shape. Fourth, female students showed higher levels of adolescence stress in all of the physical symptoms, individual characteristics, and allergy than male students, showing no difference between tension and interpersonal sensitivity. Middle school students showed higher levels of tension and high school students the physical symptoms, individual characteristics, and allergy. The results of relationships among exercise self-schema of adolescents, their physical activity, physical self-efficacy and stress are as follows. First, it was revealed that exercise self-schema level of adolescents has a direct effect on their physical activity, not on time for sitting during the day. Second, it showed that exercise self-schema of adolescents and their physical self-efficacy have a meaningful effect on running, exercise participation, muscle strength, appearance, and body shape. Third, it also showed that their physical activity level has a meaningful effect on their self-efficacy in all the parts of running, exercise participation, muscle strength, appearance, and body shape. Fourth, the physical activity of adolescents, stress symptoms, individual characteristics, interpersonal sensitivity, and allergy have positive correlations, except tension. The results of relationship analysis and model verification of exercise self-schema of adolescents, their physical activity, physical self-efficacy and stress are as follows. First, to verify the research model, using structural equation model analysis, it was identified that the cognitive, behavioral-cognitive, and affective factors in exercise self-schema of adolescents have a direct effect on their physical activity, physical self-efficacy and stress. It also showed that the higher physical self-efficacy, the higher physical activity and day time walking level, interacting with day time physical activity and day time walking factors, and that the more day time sitting, the higher stress level, with day time sitting having a direct effect on stress. Second, the higher physical self-efficacy, the lower stress level and vice versa, which is seen when the physical self-efficacy level is high in running, exercise participation, muscle strength, body shape and appearance factors. Third, physical self-efficacy has a direct effect on physical activity, suggesting a correlation effect that the higher physical self-efficacy, the higher physical activity. Fourth, with physical activity level having a direct effect on stress factors, it showed a correlation effect that the higher physical activity level, the lower stress level and vice versa. Fifth, measurement items and factors among concepts turned out to be valid through research model analysis. Sixth, based on path coefficients among each factor, the hypothesis model presented in this study proved to be a suitable one and exerts total effect and direct and indirect effects among factors. Seventh, as a result of verifying research hypothesis presented in the path coefficient analyzing the suitability of the model through the first and second model verification process, this research model proves to be acceptable, suggesting that exercise self-schema level of adolescents has a close relationship with their physical activity, physical self-efficacy and stress and provide suitable data to encourage adolescents to participate in physical activities and constantly maintain them.

본 연구는 보깅댄스(Voguing Dance)가 유희적 목적으로만 소비하는 선에서 그치지 않고, 문화 예술로의 발전 가능성을 모색하고자 시도하였다. 이러한 목적에 따라 한국의 볼 문화를 중심으로, 보깅댄스의 국내 유입과 댄스 장르로의 정착 과정을 탐색하였다. 탐색의 결과로 한국의 보깅댄스 연구의 기초자료를 수집 정리하였으며, 이와 함께 보깅댄스의 문화 예술로의 발전 및 학술 가치를 도출하는데 목적이 있다. 연구 방법은 질적 연구 방법이었고 질적 연구 방법 중에서 심층 면담 기법을 활용하였다. 반구조화 면담을 통해 얻은 서술적 자료와 국내 보깅댄스에 관련한 문헌들을 교차 검증하였으며, 선행연구를 통해 분석된 이론적 분석 틀을 바탕으로 국내 보깅댄스 유입 및 정착 과정을 볼 문화를 기반으로 분석하였다. 연구 참여자는 국내‘하우스(House)'의‘마더(Mother)'로‘칠드런(Children)'을 지도하고 있는 댄서와 해외 메이저 하우스 소속 댄서를 중심으로 선정하였다. 연구의 타당도와 신뢰도를 높이기 위해 보깅댄서로 활동한 기간이 8년 이상이며 현재까지 활동을 이어오고 있는 댄서들로 연구 참여자를 한정하였다. 구체적인 결과는 다음과 같다. 첫째, 보깅댄스의 국내 유입은 간접적 유입과 직접적 유입으로 나눌 수 있다. 간접적 유입 경로는 영상 매체, 동료 댄서의 권고, 스트릿 댄스 행사장이라는 장소를 통한 유입으로 나타났다. 직접적 유입 경로는 국내에서 보깅댄서들이 생기기 시작하던 2016년, 개최된 아치 버넷(Archie Burnett) 워크숍을 통해 춤과 문화가 직접 전수가 주된 경로였다. 이와 함께 해외 방문 한국 댄서를 통한 국내로의 정보 전달도 직접적 유입 경로임을 확인할 수 있었다. 둘째, 보깅댄스의 수용 양상은 간접적 유입의 수용양상과 직접적 유입의 수용양상으로 나눌 수 있었다. 간접적 유입의 수용양상은 비 체계 특징과 활동적 특징이었다. 직접적 유입의 수용양상으로는 워크숍을 통해 보깅댄스를 전공 장르로 수행할 수 있다는 확신 및 습득한 지적 정보와 춤의 체계화를 통해 자신의 춤 가치관에 대한 고찰과 보깅댄스에 대한 적극적 수용으로 나타났다. 셋째, 보깅댄스의 국내 정착 요인은 행사를 통한 정착, 보깅댄스 공동체의 지속적인 소통, 교육을 통한 확장, 대중매체를 통한 확산으로 분석되었다. 이러한 연구 결과를 통해 보깅댄스의 국내 유입 및 정착에 관한 전반적인 내용을 확인하였다. 보깅댄스와 볼 문화는 국내에서 뚜렷한 성장을 보이고 있다. 그럼에도 불구하고 한국 내에서 보깅댄스에 관련한 연구는 미비한 실정이다. 이러한 현실에 비추어 미개척 분야인 보깅댄스를 중심으로 한 본 연구는 보깅댄스의 기초자료의 수집 정리와 함께, 전반적인 도입 및 수용에 대한 과정 및 결과 등을 고찰하여, 문화 예술로의 발전을 모색하였다. 따라서 전반적인 유입 및 수용을 다룬다는 점에서 다른 기존의 단편적인 한국의 보깅 댄스에 대한 연구를 보강하고자 하였으며, 본 연구는 보깅댄스 연구의 토대를 마련하고 기초 자료로써 많은 도움이 될 것으로 보인다.

본 연구는 실용무용 전공자의 진로전환 경험을 통해 진로전환의 동기와 과정, 현재의 삶을 심층적으로 파악하는 것에 목적이 있다. 이를 위한 연구 방법으로 질적 사례 연구를 채택하였으며, 연구문제는 첫째, 실용무용 전공자의 진로전환 동기는 무엇인가? 둘째, 실용무용 전공자는 진로전환 과정에서 어떤 경험을 하는가? 셋째, 실용무용 전공자 진로전환 이후의 삶은 어떠한가? 이다. 연구 참여자는 유의 표집 방법을 통해 대학 실용무용과를 졸업한 20~30대 중 졸업 후 2년 이상이 된 자를 선정하였으며, 새로운 직업을 가진 기간이 최소 1년 이상인 자를 기준으로 총 7명을 선정하였다. 2022년 12월부터 2023년 3월까지 약 4개월에 걸쳐 심층 면담을 통한 자료수집을 진행하였다. 연구 과정에서 타당성과 신뢰도 확보를 위해 Guba와 Lincoln(1985)이 제시한 사실적 가치(truth value), 적용 가능성(applicability), 일관성(consistency), 중립성(neutrality)의 네 가지 질적연구 평가 기준을 적용하여 연구를 수행하였다. 자료수집과 분석과정을 순환적으로 시행하였으며, Stake(1995)가 제시한 질적 사례 연구 분석 방법의 ‘사례 내 분석’과 ‘사례 간 분석’을 통해 결과를 도출하였다. 연구 결과, 3개의 핵심 주제와 7개의 상위범주, 24개의 하위범주가 도출되었다. 첫 번째 핵심 주제인 연구 참여자들의 <진로전환 이전의 경험> 에서 3개의 상위범주가 도출되었다. 이는‘좋아하는 마음에 결정한 진로’,‘한계에 직면’,‘자발적 진로전환 결정’으로 나타났다. 두 번째 핵심 주제인 연구 참여자들의 <진로전환 과정의 경험>에서 2개의 상위범주가 도출되었으며, 이는 ‘적응과정에서의 난관’, ‘어려움을 헤치다’로 나타났다. 세 번째 핵심 주제인 <현재의 삶>에서는 2개의 상위범주가 도출되었으며, 이는‘댄서였기 때문에’, ‘내가 선택한 길, 내가 선택할 길’로 나타났다. 이를 통해 본 연구는 다음과 같은 결론을 얻었다. 첫째, <진로전환 이전의 경험>에서 연구 참여자들은 흥미와 적성을 고려하여 진로를 자발적으로 설정하였으며, 실용무용 전공 과정과 댄서활동을 병행하면서 자신이 설정한 진로의 직업사회를 미리 경험하였다. 그 과정에서 경제적 안정에 대한 필요성을 크게 인식한 것을 알 수 있었으며, 이에 ‘실용무용 진로 인식’과 ‘자신에게서 느낀 한계’가 진로 전환의 결정적 계기로 나타났다. 둘째, <진로전환 과정의 경험>에서 연구 참여자들은 정보와 지식의 부족을 경험하였으며, 새로운 업무와 환경에 대해 어려움을 겪었다. 진로전환 과정에서 주변인에게 도움을 요청하거나 스스로 학습하는 것을 통해 어려움을 해결했으며, 이후 직무에서 얻는 성취감이 새로운 직업에 도움이 된 것으로 나타났다. 연구 참여자들은 공통으로 실용무용을 전공한 것이 전환한 직업에 도움이 되었다고 하였다. 셋째, 연구 참여자들의 <현재의 삶>에서‘댄서였기 때문에’겪는 감정으로‘춤에 대한 아쉬움’, ‘여전히 춤추는 사람들을 보며’, ‘후회 없는 전공 선택’, ‘전공 과정의 진로교육’이 하위범주로 나타났다. 모든 연구 참여자들은 현재 전환한 직업에 만족하는 수준으로 나타났으며, 각자 자신이 설정한 목표를 위해 정진하고 있는 것을 알 수 있었다. 본 연구를 통해 도출된 결과를 바탕으로 실용무용 전공생의 복지 및 권리에 대한 교육, 체계적인 진로 교육과 상담 프로그램 개발, 직업 현장에 관한 연구, 실용무용 전공생의 심리적 요인과 무용 지속에 관한 연구를 제언하였다. 본 연구의 결과를 통해 실용무용 전공생들의 진로 불안과 진로전환에 대한 상담적, 제도적 이해를 높일 수 있을 것을 희망해 본다.
