Purpose: The purposes of this study are to elucidate better strategies that can improve the policy to promote participation in sport for older adults. Method: Delphi technique and qualitative content analysis were used for the study. Results: The analysis reached the following results. First, the existing laws were not sufficient to specifically regulate the sports policy for older adults. To improve this problem, it should be guaranteed through the enactment of Sport Basic Law and the mandatory regulations about instructors and equipment. Second, in relation to the implementation framework for sport policy for older adults, there were problems such as a lack of cooperation among related ministries, policy enforcement through administrative convenience, and the absence of a control tower. To improve this problem, it is necessary to reorganize the implementation framework, e.g. clarifying the roles and objectives of the ministries. Third, the sport policy projects for older adults were being operated according to short-term goals and the programs provided did not reflect the elderly characteristics. To improve this problem, a long-term roadmap should be established and a subdivided program considering the characteristics of the elderly should be prepared. Fourth, the budget for the sport policy for older adults was not sufficient. To improve this problem, it is necessary to commit the public financial resources to the elderly with poor levels of physical function and economic conditions to achieve the effective allocation of the budget. Fifth, there was no easy-to-use sports facility environment for old adults. To improve this problem, It is necessary to create an environment that can be easily used, such as providing mandatory programs for the elderly in public sports facilities. Sixth, there was a problem with the lack of professionalism of sports instructors for older adults and with the instructor training system. To improve this problem, It is necessary to reorganize the training system strengthening expertise for sports instructors for older adults. Seventh, the direction of improvement, which has been highly agreed on by all professionals, was to ‘clarifying the roles and goals of relevant ministries’. Conclusion: In conclusion, in order to solve the problems and achieve the effectiveness of the sport policy for older adults, the clarification of the roles and goals of the departments related to sport policy for older adults should be considered first among various improvement directions.

The purpose of this study is to comparatively analyze the baby boomer generation and the existing older generation, focusing on the factors of sports participation, and to prepare the basis for practical intervention to promote the baby boomer generation"s sports participation. The analysis data is the a national survey on physical activity participation in Korea in 2019, and the subject of the study is a total of 2,950 people including baby boomers and the elderly. The statistical methods are frequency analysis, Chi-square test. The main results are as followings. First, with regard to sports participation, the baby boomer generation maintained higher levels than the elderly generation in the degree of participation, and participation intensity, indicating that they were participating in more active sports outside of low-intensity physical activity. Second, the baby boomer generation showed a higher rate of use of private sports facilities and higher reasons for specialized facilities and various programs, indicating that the need for facilities was higher than that of the elderly generation. Third, it was found that the baby boomer generation had higher awareness of sports facilities than the elderly and used the internet more in collecting sports-related information. Fourth, the reasons for participation in sports of the baby boomer generation are high due to health-related factors, but the reasons for self-actualization and personal enjoyment are the reasons that are different from the older generation. According to these differences, the future direction of for sport for older adults is to 1) Adjustment of the age range, 2)Supply of more active programs, 3) Expansion of public sports facilities, 4) Making multi-channel programs for sport for older adults through the use of the internet 5) Providing dissemination of sports events in a modified form.

OBJECTIVES The purpose of this study was to investigate the effects of assist and resistance torque on the spatiotemporal gait characteristics, and the symmetry and asymmetry of gait using a Gait Enhancing and Motivating System (GEMS) in the elderly. METHODS A cross-sectional and repeated measure design was used. A total of 18 participants (9 males, 9 females; age: 63.5 ± 5.02 years; mass: 64.26 ± 6.87 kg; height: 164.06 ± 7.15 cm) were recruited from a local community, and spatiotemporal gait data were collected with OptoGait system and GEMS. Spatiotemporal gait variables and differences between the dominant and non-dominant legs of these variables were assessed (step length, step time, stance phase, swing phase, single support, load response, pre swing phase, stride time, stride length, double support, cadence, and gait speed). The effects of three modes including normal, assist, and resist modes using GEMS were investigated twice for each participant on a 9-meter walkway. A one-way repeated measure analysis of variance followed by Bonferroni post-hoc tests was conducted. RESULTS The assist mode increased step time, swing phase, stride time and reduced stance phase, pre-swing phase, double support, cadence, and gait speed as compared to normal mode. The resist mode increased stance phase, load response, pre-swing phase, double support, cadence, and reduced step time, swing phase, and stride time. In dominant leg, assist mode showed increased step time and reduced pre-swing phase than normal mode, and greater step time than resist mode (p < 0.05). However, there was no effect of external torque on symmetry and asymmetry between both legs (p > 0.05). CONCLUSIONS The resistance and assist torque of GEMS alter spatiotemporal characteristics during the stance and swing phase of gait in the elderly. However, the resistance torque and assist torque of GEMS did not increase or decrease the gait asymmetry between the dominant and non-dominant legs.

양가현(Yang, Ka-Hyun),정경환(Jung, Kyunghwan),원영신(Won, Young-Shin) 한국스포츠사회학회 2021 한국스포츠사회학회지 Vol.34 No.2

연구의 목적은 산속 헬스장에서 운동하는 노인들의 경험을 심층적으로 탐구하여 노인의 체육활동에 대한 학술적 인식을 확장하는 데 있다. 이를 위해 질적연구의 한 전통인 현상학적 방법을 적용하였다. 연구자는 예비조사를 통해 산속 헬스장 현황을 파악하였고 실제 현장조사를 통해 S구에 위치한 산속 헬스장 두 곳을 선정하였다. 선정된 두 곳의 산속 헬스장에서 2020년 4월부터 11월까지 참여관찰을 진행하고 산속 헬스장을 이용하고 있는 8명의 노인을 연구참여자로 선정하여 심층면담을 진행하였다. 노인이 그들의 생활세계에서 경험한 산속 헬스장에서 운동 체험의 의미는 다음과 같았다. 첫째, 산속 헬스장의 형성과 유지는 ‘자율적 동기’에 의해 이루어졌다. 산속 헬스장은 생활체육 공간의 부족이라는 제약 속에서 운동을 좋아하는 사람들이 자발적으로 모여 개척한 공동의 운동장소이다. 산속 헬스장 이용은 중년기 이후 찾아온 신체적 노화를 극복하기 위해 자율적으로 이루어졌고 야외 운동이 가진 매력과 다른 장소에서 운동했을 때의 불편한 경험이 산속 헬스장을 지속적으로 이용하게 된 중요한 동기로 작용하였다. 둘째, 산속 헬스장은 ‘주체적 참여의 장’으로 연구참여자들은 자발적으로 산속 헬스장의 시설을 함께 관리하며, 운동 효과에 대한 지식과 운동 목적에 대한 이해를 가지고 웨이트트레이닝을 비롯한 다양한 운동 종목에 참여하고 있었다. 또한 꾸준히 운동에 참여해야 한다는 신념과 강한 의지로 운동 참여를 지속하고 있었다. 셋째, 체육 참여 공간으로서 산속 헬스장은 ‘상호 교류의 장’으로서 역할을 하였다. 산속 헬스장의 회원들은 운동이라는 공통의 목적과 관심사를 토대로 형성된 연대감으로 친목을 도모하며, 정보교류의 장으로써 활발한 운동 지식공유를 통해 서로의 발전을 도모하였다. 또한 외부인에게도 친절한 분위기를 형성하여 신규 회원을 유입하는 개방적 소통 문화를 가지고 있었다. 결론적으로 산속 헬스장은 자율과 주체의 장이자 상호 교류가 이루어지는 공간으로서 노인체육 문화에 있어서 중요한 의미를 가지고 있으며, 노인체육의 질적 성장을 위한 정부정책 방향성 마련에 있어서 중요한 함의를 제공한다. The purpose of this study is to expand the academic awareness of sports for old adults by exploring their experience of participating in exercise at the outdoor fitness club in a mountain. This study was applying the phenomenological research method. After conducting the first preliminary on-site survey, two mountain fitness clubs actively used by the elderly were selected, and field notes and participant observation were conducted. In-depth interviews were conducted by selecting eight elderly who are using the outdoor fitness club in a mountain actively and steadily as the study participants. The research period is from April to November 2020. The results obtained through research and exploration are as follows. Firstly, the outdoor fitness club in a mountain was formed and maintained by ‘autonomous motivation’. The outdoor fitness club in a mountain is a joint sports place that people who like sports gathered and pioneered under the constraints of lack of space for living and sports. The use of the outdoor fitness club in a mountain was made autonomously in to overcome the physical aging that came after middle age, and the attractiveness of outdoor exercise and the uncomfortable experience of exercising in other places served as an important motive for continuing to use the outdoor fitness club in a mountain. Secondly, the outdoor fitness club in a mountain acts as a "place for independent participation". The elderly participants voluntarily manage together the facilities of the place, and participate in various sports events including weight training, with knowledge of exercise effects and an understanding of their own exercise purposes. In addition, they continued to participate in the movement with a strong will and the belief that he should continue to participate. Thirdly, as a space for participation in sports, the outdoor fitness club in a mountain served as a ‘place for mutual exchange". Members of the outdoor fitness club in a mountain promote friendship with a sense of solidarity based on the common purpose and interests of exercise and form an atmosphere of kindness to outsiders, which leads to the influx of new members. In addition, the outdoor fitness club in a mountain promotes the development of each other through active exercise knowledge sharing as a venue for information exchange. In conclusion, the outdoor fitness club in a mountain, as a place for autonomy and independence as well as space for mutual exchange, has an important meaning in the elderly sports culture and provides important implications in preparing the government direction for qualitative growth of the sports policy for older adults.

[목적] 본 연구는 은퇴 프로축구선수들의 재사회화 장벽에 관한 수용인식(주관성)을 유형화하는데 그 목적이 있다. [방법] Q방법론을 차용하여 은퇴 선수들이 지각(또는 경험)한 사회적응 및 재취업 과정에서의 제약요인을 규명하였다. [결과] 은퇴 프로축구선수들의 재사회화 장벽은 ‘유형Ⅰ: 내적-제약형’, ‘유형Ⅱ: 외적-제약형’, ‘유형Ⅲ: 내적-갈등형’, ‘유형Ⅳ: 외적-갈등형’으로 나타났다. 이들 유형은 재사회화 장벽을 어디로부터 수용하는지(개인 내부와 외부), 무엇에 의존하는지(객관적 조건과 주관적 관념)에 따라 다양한 학술적 및 실용적 논의를 제공하였다. [결론] 본 연구는 개인의 주관성 구조, 즉 가설 추론(발견)에 초점화된 연구로서 가설 검증에 주목한 전통 방법론을 보완하였다. 따라서 본 연구에서 발견한 각 유형들은 은퇴 선수와 관련된 후속 연구뿐만 아니라 지원사업과 같은 정책 결정 과정에도 유용한 정보를 제공한다. [Purpose] The purpose of this study is to classify the subjectivity of re-socialization barriers among retired footballers. [Methods] Q methodology was conducted to identify constraint factors contributing to social adjustment and reemployment perceived by 28 P-samples. [Results] Re-socialization barriers were classified as ‘Type I: Internal-constraint’, ‘Type II: External-constraint’, ‘Type III: Internal-conflict’, and ‘Type IV: External-conflict’. These types provided a variety of academic and practical discussions, depending on where the barriers are taken from (internal and external) and what depends on them (objective conditions and subjective ideas). [Conclusions] This study focused on the subjective structure of retired footballers and complemented traditional methodology focusing on hypothesis testing. Therefore, each type found in this study provides useful information not only in follow-up study on retired athletes, but also in policy-making decision such as support projects.

진단용 엑스선 촬영장치에서 발판 스위치의 유용성 평가

권혁진(Hyeokjin Kwon),정홍문(Hongmoon Jung),정재은(Jaeeun Jung),정경환(Kyunghwan Jung),원도연(Doyeon Won) 한국방사선학회 2018 한국방사선학회 논문지 Vol.12 No.5

방사선사는 일반촬영 시에 다양한 환자를 만나게 된다. 노령환자, 유아 등 몸이 불편한 환자를 검사하게 된다. 소규모의 병·의원에는 방사선사가 혼자 업무를 보는 경우가 자주 발생한다. 이러한 경우 방사선사의두 손은 환자의 자세를 유지하는데 사용되어지기 때문에 촬영에 있어서 어려움을 느끼게 된다. 본 연구는 이러한 문제점을 극복하고자 진단용 방사선 발생 발판 스위치를 고안하여 실험하였다. 제작한 발판 스위치를 진단용 엑스선 촬영장치에 장착하여 조사선량 재현성 시험, kVp, mAs, 백분율평균오차와 같은 정량적 평가를 실시하였다. 결과적으로 발판 스위치 사용에 대한 정량적 평가는 조사선량 재현성 시험에서 변동계 수가 0.05이하로 측정되었고 kVp 시험에서는 백분율 평균오차가 ± 10% 이내로 측정되었다. mAs 시험에서도 백분율 평균오차가 ± 20% 이내로 측정되었다. 이는 진단용 방사선 발생장치의 검사기준 범위에 모두 부합하여 사용상 문제점은 제시되지 않았다. 또한 현재 근무 중인 방사선사를 상대로 유용성에 관한 정성적 평가를 실시하였다. 결론적으로 발판스위치의 엑스선 발생효율의 정량적 평가에서는 실험된 검사가 엑스선 발생장치 장비 기준 범위에 부합하였으며 설문을 통한 평가에서도 먼저 병·의원에서 근무하는 방사선 사를 상대로 발판 스위치를 사용한 이후 설문을 통해 발판 스위치에 대한 편리성과 활용성에 대해 설문 실시한 결과는 발판스위치 사용은 임상에서 많은 도움을 줄 수 있는 긍정적인 결과로 나타내었다. 그러므로 진단용 엑스선 촬영용 발판 스위치를 사용하면 방사선 기술자 작업의 신속성과 정확성을 효과적으로 향상 시킬 수 있으므로 의료 서비스 만족도를 높이는 데 효과적으로 사용할 수 있을 것이다. A foot pedal switch in the diagnosis x-ray radiography system has been researched to improve radiologic technologist works and patient satisfaction. The switch has been installed in the diagnosis x-ray radiography system used in domestic clinics. Quantitative evaluation has been conducted by measuring the exposure dose reproducibility test, tube voltage, mAs, and percentage average error. Qualitative evaluation has been conducted by analysis of the radiologic technologists questionnaire. In the quantitative evaluation for the use of the foot pedal switch, the coefficient of variation was less than 0.05 in the exposure dose reproducibility test. In the mAs test, percentage average error of ± 20% was measured. There was no problem raised since it meets the all inspection standards of the diagnosis x-ray generator. In the qualitative evaluation, most of the opinions are that it has a clinical value for the foot pedal switch in the diagnosis x-ray radiography system. Therefore, developing the foot pedal switch for the diagnosis x-ray radiography system can improve effectively the rapidity and accuracy of the radiologic technologist work. In addition, it is effective in decreasing the x-ray exposure of patients and increasing satisfaction for the medical service due to reduction of retaking x-ray.
