정은영(Eunyoung Chung) 한국노년학회 2020 한국노년학 Vol.40 No.3
본 연구는 한국 남녀 노인의 여가활동과 인지기능 간 관계를 탐구하는데 그 목적이 있다. 연구의 목적을 위해 국내 지역사회에거주하고 있는 65세 이상 노인에 대한 대표성 있는 자료인 노인실태조사 자료를 활용하여 주요변수에 대한 결측값이 없는 10,055명에대해 로지스틱 회귀분석을 실시하였다. 여가활동은 생산적 및 소비적 여가활동, 미분류 활동의 세 가지 유형으로 구분하였으며 치매선별용 한국어판 간이정신상태검사(Mini Mental Status Examination for Dementia Screening)의 연령, 성별, 교육수준별 기준 점수에 미달하는경우 인지기능 장애가 있는 것으로 보았다. 연구결과 여가활동 유형 중에서 생산적 여가활동이 유일하게 남녀 한국 노인의 인지기능장애 관련 요인으로 나타났으며 소비적 여가활동과 미분류 활동은 유의한 관계를 확인할 수 없었다. 생산적 여가활동 외에 연령, 교육수준, 경제활동 참여, 주관적인 청각 장애 및 우울감이 유의한 관련변수로 나타났다. 본 연구결과를 통해 향후 노인 여가정책에 대한방향을 제시하였다. Aim: This study investigated the association between leisure activities and cognitive impairment in Korean community-dwelling older adults. Methods: Among participants of the 2017 National Survey of Older Koreans, 10,055 (male=4,277, female=5,778) were included in this cross-sectional study. To better identify the association between late-life cognition and leisure activities, individual leisure activities were categorized into 3 types including productive, consumptive, and unclassified activities. Multivariate logistic regression analysis was performed to assess the association between participation in leisure activities and cognitive impairment when controlling for possible covariates evidenced by previous studies. Results: Male participants were more likely to be cognitively impaired than female ones with significant differences in all the covariates. After controlling for confounding variables, involvement in productive leisure activities was found to be associated with cognitive function in both male and female groups, along with age, educational level, depressive symptoms, subjective hearing problems, and occupational status. Conclusion: Involvement in productive leisure activities might be associated with decreased risk of cognitive impairment in later life. Appropriate strategies to encourage older adults to participate in productive leisure activities should be established to help them maintain their cognitive function.

Purpose: The purpose of this study was to explore individual, interpersonal, and environmental correlates associated with excessive leisure-time sedentary behavior among older Korean adults residing in urban and rural area. Methods: Using data from 2017 National Older Koreans involving 10,052 (urban=6,912, rural=3,140) participants,we performed multivariate logistic regression analysis to calculate the odds ratios of excessive leisure-time sedentary behavior (≥5 hours per day) for each individual, interpersonal, and environmental factors, stratified by residential area. Results: Excessive leisure-time sedentary behavior was associated with several individual and interpersonal factors including number of comorbidity, exercise time, work time, and neighborhood relationship for the whole sample. Access to facilities was found to be a significant correlate only for the participants in rural area.Conclusion: The findings showed that excessive leisure-time sedentary behavior was associated with not only individual factors including socio-demographic, health status and behavioral characteristics but also interpersonal factors such as relationship with neighborhood. Furthermore, it should be noted that the environmental factor was also important to older adults residing in rural area. Intervention programs to reduce sedentary time of older adults may be more effective if they take these factors into account.

As the concern of steel scrap recycling increase and interest is on economical production of steel, the amount of production of steel produced electro furnace is growing. This had led to speculation about applying steel produced electro furnace to steel of car body made only by shaft furnace. It was found that the tramp element contained in steel scrap obstructs the coating of zinc-phosphate pretreatment under investigation. As performance of zinc-phosphate pretreatment is connected directly with performance of anti-corrosion, it results in fatal consequence about anticorrosion when the zinc-phosphate pretreatment is made up improperly. Consequently, in this study we cleared the cause obstructing the coating of zinc-phosphate pretreatment and expanded the application scope through the improving of the zinc-phosphate pretreatment for application of steel produced electro furnace to steel of car body.
