본 연구는 만 65세 이상의 노인 49명을 대상으로 가속도계와 신체활동일기를 함께 사용하여 신체활동량과 좌식행동패턴을 성별에 따라 비교하고 WHO 신체활동지침의 실천율을 평가하였다. 1. CPM과 METs는 성별에 따른 유의한 차이가 없었으나 PAEE는 남자가 여자보다 유의하게 높았다. 활동 강도별 1일 평균 소요시간을 살펴보면, 본 연구대상자들은 좌식행동에 소요되는 시간 (남녀 각각 60.6%, 57.6%)이 가장 많았으며 좌식행동 및 중 고강도 활동의 소요시간에서는 남녀간의 유의한 차이를 보이지 않았으나 저강도 활동의 소요시간은 여자가 $364.2{\pm}74.5$분으로 남자 ($313.7{\pm}70.8$분)보다 유의하게 많았다. 2. 남녀 모두 수면시간을 제외한 좌식행동 (2 ~ 5단계) 중 2단계의 '휴식, 담화 및 TV보기' 활동으로 가장 많은 시간 (남자 26.9%, 여자 22.0%)을 보내고 있었으며, 남자가 $388.0{\pm}134.3$분으로 여자 ($316.1{\pm}65.2$분)보다 유의하게 많았다. 저강도 활동에 포함되는 활동 중에서는 7단계의 '미용 및 옷 갈아입기' 활동과 9단계의 '음식 준비 및 정리하기' 활동의 소요시간에서 여자가 남자보다 유의하게 많았다. 중 고강도 활동에서는 15단계의 '체조, 탁구 및 자전거타기' 활동의 소요시간에서 남자가 여자보다 유의하게 많게 나타났다. 3. 좌식행동패턴을 성별에 따라 비교한 결과, 좌식행동을 30분과 40분 이상 지속한 횟수에서 남자가 각각 $3.10{\pm}1.34$회, $1.78{\pm}1.09$회로 여자 ($2.34{\pm}1.22$회, $1.32{\pm}1.07$회)보다 유의하게 많았으나 시간당 좌식행동의 지속을 끊어주는 횟수는 남자 ($5.74{\pm}0.89$회)가 여자 ($6.44{\pm}0.71$회) 보다 유의하게 적었다. 좌식행동을 30분 이상 지속한 횟수 및 시간 당 좌식행동을 끊어주는 횟수는 2단계의 '휴식, 담화 및 TV보기' 활동의 소요시간과 유의한 상관관계를 보였으며 주로 저강도 활동을 통해서 좌식행동의 지속이 끊어지는 것으로 나타났다. 4. 일주일 동안 중 고강도 활동을 각각 2분과 5분 이상 지속한 시간에서는 남자가 $319.8{\pm}255.2$분과 $247.3{\pm}228.2$분으로 여자 ($193.3{\pm}130.6$분, $137.2{\pm}101.9$분)보다 유의하게 많은 것으로 나타났다. 또한 본 연구대상자의 경우 중 고강도 활동의 짧은 지속시간 (10분 미만)으로 인하여 WHO 신체활동지침의 실천율이 22.4% (남자 30.8%, 여자 13.0%)으로 매우 낮았다. 본 연구 결과를 통하여 노인의 경우 장시간 지속되는 좌식행동 패턴을 줄이기 위하여 노력해야함을 알 수 있었다. 이를 위하여 무엇보다도 앉아서 TV를 시청하는 시간을 줄이는 것이 중요함이 지적되었다. 앞으로 노인의 만성질환 예방을 위하여, 노인의 신체활동량 및 좌식행동 패턴과 건강 관련 지표와의 관련성 분석 평가 연구가 필요하다. 특별히 본 연구에서 노인만을 위한 별도의 신체활동지침 마련의 필요성이 제시된 바, 노인에게 적합한 신체활동의 적정 강도 및 적정 유지 시간 등이 반영된 새로운 지침이 개발되어야 할 것이다.

This paper aims to approach a spatial furniture for sedentary lifestyle which been has derived and evolved from Korea's traditional 'Ondol' heating system. In this living culture, people has been staid on the floor where people would sit directly on without furniture such as chair and bed. With every changing technological advances, sedentary life culture is transformed and mixed instead of sedentary habit. Most of people lived in western house such as apartment forms. As time go by, western furnitures were used became widespread. However, during the process, it impossible to acclimate ourselves to the new lifestyle such as chair, bed etc. This leads to users feeling uncomfortable on certain points. The researcher suggests a spatial furniture through a new approach to rest-taking that also intersects the cultures of East and West while resolving the a fore-mentioned issues. The study is conducted as follows. Firstly, issues are discovered through a user's lifestyle to exist usage and interplay of house and furniture. Furthermore, the issues was not a fragmentary thing but more related to a culture and a coustom of long standing. Secondly, a design experiment is conducted to conclude a new form and function that is better fit for the Korean culture where sitting on the floor is the norm. New direction for space that intersects the cultures of the East and West while using modules made convenient for contemporary life is presented. Finally, this study is meaningful in that it reinterprets furniture used for rest within the context of sedentary culture, in order to propose a new direction and value for design that overcomes the boundaries between eastern and western applied to resting space.

The purpose of this study was to analyze the patterns and interrelationships for meeting recommendations of physical activity, sedentary behavior, and dietary behavior in elementary school students. A cross-sectional design was used to assess 259 students ages 11 to 13 years. Physical activity (moderate to vigorous physical activity $\geqq$60min/day), sedentary behavior (viewing time for TV, computer, DVD, video, etc<3hr/day), and dietary behavior (servings of fruits and vegetables$\geqq$5times/day) were categorized into two levels: meeting recommendations or not meeting recommendations. Parents' health behaviors and home environmental variables were assessed with self-reported measures. Chi-squared tests and independent t-tests were conducted to compare anthropometric variables and the prevalence of students not meeting the recommendation for the three health behaviors. Comparison between males and females and logistic linear regression were used to determine the interrelationships of three health behaviors. 25.9% of students did not meet the physical activity recommendations. 15.4% did not meet sedentary behavior recommendations, and 41.7% did not meet dietary recommendation. Only 39.8% of students met all three recommendations, but 19.0% did not meet over two recommendations. Patterns that simultaneously did not meet two recommendations were: sedentary and dietary behavior in males (8.1%), and physical activity and dietary behavior in females (10.4%). Students who did not meet dietary recommendations were at greater risk of not meeting physical activity (OR 2.76; 95% CI 1.15 to 6.64), and sedentary behavior (OR 3.07; 95% CI 1.15 to 8.16) compared with students who did meet dietary recommendations. The findings of this study support not an independent behavior approach but a multiple behavior approach taking into account gender and interrelationships among the three behaviors.

Purpose - Due to the lack of physical activities and the increase of sedentary behaviors such as screen time, the health condition for contemporaries has been deteriorating. This study is designed to investigate how the use of worktable or tools unfit for body and sedentary behaviors can exercise influence on muscular skeletal disease and how it has an impact on lowering work efficiency and the quality of life with the medium of the muscular skeletal disease. Research design, data, and methodology - The research has developed a questionnaire with 5 hypothesis. The questionnaires were also made by interview and E-mail. 350 copies of questionnaires were distributed and 315 questionnaire were used for the analysis as valid data responses. SPSS ver.22.0 were used and made Cronbach's and reliability test, correlation, Baron & α Kenny 3 step mediated regression analysis. Results - The research has found that living environment factors have positive effect on the occurrence of musculosketal disease. Particularly, repeated use of unfit worktable or tools has a positive effect on the muscular skeletal disorder. And sedentary lifestyle also has a positive effect on the disease. The musculoskeletal disease caused by living environment has a positive impact on lowering the work efficiency. This study has also showed that the muscular skeletal disease has mediated the relationship between the living environment factors and the decrease of work efficiency due to musculoskeletal disease. The musculoskeletal disorders can effect the decrease of the quality of life as well, for the decrease of work efficiency has a positive effect on lowering the quality of life. Conclusions - Sedentary lifestyles, the use of worktable unfit for body, and the repeated use of a tool have caused the increase of muscular-skeletal diseases, and reduction of productivity as well as the hight cost of medical treatment for our contemporaries. Understanding the cause of disease morbidity, finding ways to prevent the disease, and educating people about them would contribute not only to improvement of individual health but also to the advancement of welfare for all.

Background: Prolonged sitting at work can lead to adverse health outcomes. The health risk of office workers is an increasing concern for the society and industry, with prolonged sitting work becoming more prevalent. Objective: This study aimed to explore the variation in muscle activities during prolonged sitting work and found out when and how to take a break to mitigate the risk of muscle symptoms. Methods: A preliminary survey was conducted to find out the prevalence of muscle discomfort in sedentary work. Firstly, a 2-h sedentary computer work was designed based on the preliminary study to investigate the variation in muscle activities. Twenty-four participants took part in the electromyography (EMG) measurement study. The EMG variations in the trapezius muscle and latissimus dorsi were investigated. Then the intervention time was determined based on the EMG measurement study. Secondly, 48 participants were divided into six groups to compare the effectiveness of every break type (passive break, active break of changing their posture, and stand and stretch their body with 5 or 10 mins). Finally, data consisting of EMG amplitudes and spectra and subjective assessment of discomfort were analyzed. Results: In the EMG experiment, results from the joint analysis of the spectral and amplitude method showed muscle fatigue after about 40 mins of sedentary work. In the intervention experiment, the results showed that standing and stretching for 5 mins was the most effective break type, and this type of break could keep the muscles' state at a recovery level for about 30-45 mins. Conclusions: This study offers the possibility of being applied to office workers and provides preliminary data support and theoretical exploration for a follow-up early muscle fatigue detection system.

이 연구는 불안정 지지면 코어운동이 안정 지지면의 코어운동에 비해 요통이 있는 여성 좌업근로자의 기능적 움직임, 균형력 및 통증에 더 효과가 있는지를 분석하는 것이 목적이다. 요통이 있는 여성 좌업근로자 20명을 불안정 지지면 코어운동 집단(UEG; n=10)과 안정적 지지면 코어운동집단(SEG; n=10)으로 무작위 배정한 후, 불안정 지지면 코어운동과 안정 지지면 코어운동 프로그램을 집단별로 8주간 적용하였다. 운동처치 전·후 FMS, Y-Balance 및 VAS를 측정하여 모든 측정결과에 대한 반복이원변량분석을 실시하였고, 시기와 집단 간 상호작용이 있을 경우 집단 별로 대응표본 t-test를 실시한 결과는 다음과 같다. FMS는 UEG의 HS(p<.01), ASLR(p<.05) 및 TS(p<.001)에서 유의한 효과가 나타났으며, 그 외의 변인에서는 유의한 효과가 없었다. YBT는 AT, PL, PM, TS의 모든 변인에서 집단별 유의한 효과가 나타나지 않았지만, 모든 집단에서 시기 간에 유의한 차이가 있었다. VAS는 UEG집단에서 유의하게 감소하는 효과가 나타났다(p<.001). 결론적으로 여성 좌업근로자의 불안정 지지면 코어운동은 안정지지면 코어운동에 비해 기능적 움직임과 통증에는 효과가 있지만, 균형력 발달에는 효과가 미미한 것으로 나타났다.

본 연구는 사무직 근로자를 대상으로 비타민 D 상태와 생활습관위험인자간의 연관성을 조사하고자 하였다. S시의 30세 이상 사무직 근로자 515명(남 336명, 여 179명)을 대상으로 혈청 비타민 D 수준, 비만지표, 체력, 대사성위험인자 및 혈중 지질 그리고 좌식습관을 포함한 생활습관위험인자를 측정하였다. 혈청 비타민 D 수준을 기준으로 결핍(<20 ng/mL), 부족(20-29 ng/mL), 충분(≥30 ng/mL) 집단으로 구분하고, 집단 간 생활습관위험인자를 비교하였다. 분석결과, 비타민 D 수준이 높아질수록 체지방율(p=.030)과 좌식습관(p<.001)은 통계적으로 유의하게 감소하는 선 경향성이 나타났으며, 골격근량(p=.037), 심폐체력(p<.001) 그리고 HDL-C(p=.013)은 통계적으로 유의하게 증가하는 선 경향성이 나타났다. 또한 심폐체력이 낮은 집단이 높은 집단보다 비타민 D 부족 또는 결핍에 노출될 상대적 위험도가 남녀 각각 2.144배(95%CI .469-1.808, p=.042), 1.971배(95%CI .305-1.974, p=.045) 정도 높게 나타났으며, 좌식시간이 가장 많은 집단이 가장 적은 집단보다 비타민 D 부족 또는 결핍에 노출될 상대적 위험도는 여성 사무직 근로자 집단에서만 1.262배(95%CI 0.074-1.527 p=.043) 정도 높게 나타났다. 이와 같이 본 연구에서는 사무직 근로자의 낮은 비타민 D 수준은 낮은 심폐체력 및 장시간의 좌식습관과 관련성이 있는 것으로 나타났다. 따라서 사무직 근로자의 건강증진과 충분한 비타민 D 공급을 위해 건강한 생활습관 변화와 근무 환경 개선이 우선적으로 필요할 것으로 판단된다.
