Older people have increased interest and involvement in controlling their aging body through physical exercise and dieting. This study examined the relationship between body image and the participation of older people in exercise and dieting. Two measures of body image (appearance attitude and appearance orientation) were used to study their relationships to participation in exercise and dieting among older people. Data were collected via a mail survey of older married couples residing in three U.S. metropolitan areas of Florida. A total of 94 couples who were 60 years older participated in this study. Multiple regression was run separately for men and women. The results indicated that for both men and women, appearance attitude was inversely related to dieting and positively related with exercise (even though the relationship with exercise was weak for men). Appearance orientation was not significantly related to exercise or dieting for both men and women. A new scale development on body image for an aging population was suggested. Various activities performed by aging people to manage their aging body and appearance need to be studied as related to physical and psychological well-being that includes body image.

Purpose: This was a methodological study that aimed to develop a measurement scale for aging anxiety among middle-aged women. Methods: In this study, construct factors were extracted, and a conceptual framework was established through an extensive literature review and in-depth interviews with middle-aged women. Under the conceptual framework, 44 preliminary items were constructed, and a preliminary scale of 25 items was completed after two rounds of expert validation and item review. For this study, data were collected from 201 women aged 40~59 years, and the construct validity and reliability of the preliminary scale were verified. Results: To verify the construct validity, exploratory factor analysis was conducted. Four factors containing 19 items were extracted. Concurrent validity of the developed scale was verified with Pearson's correlation analysis. The final scale comprised 4 factors ("Social valueless", "Physical weakness", "Concern about changes in appearance", and "Expectations of old age") and 19 items. The Cronbach's ${\alpha}$ value was .91. Conclusion: The scale for measuring aging anxiety in middle-aged women developed in this study validly reflected the peculiarities of aging anxiety in middle-aged women, who experience many physical, emotional, and social changes. The scale can be said to reflect the cultural background, as it reflected real experiences gained through in-depth interviews with middle-aged women.

인체 조직은 노화 현상을 겪으면 산화로 인한 손상이 진행되어 구조적인 변화가 일어나고 물성 저하를 겪는다. 피부가 겪는 노화 과정은 잘 알려져 있고 많은 평가가 수행되고 있지만 상대적으로 모발(머리카락)의 노화에 의한 평가는 잘 진행되어 있지 않아 모발의 노화를 케어하는 연구가 어려운 실정이다. 이에 본 연구는 모발의 노화 현상을 케어할 효능 기작을 적용할 수 있도록 노화된 모발 샘플을 제작하고 물성을 평가하여 안티에이징 효능을 확인하는 것을 목적으로 진행하였다. 먼저 내인성 노화가 진행된 모발의 지질량을 외인성 노화를 진행시킨 시료들과 비교한 결과, 펌 1회 처리 모발이 60대의 모발 지질량과 가장 유사함을 발견하였고, 이 모발을 통해서 원자 현미경으로 나노 스케일의 거칠기와 매크로 스케일의 인장강도를 평가하여 내인성 노화 모발과 유사한 물성 값을 가지고 있음을 확증하였다. 실제로 펌 처리를 통해 외인성으로 노화시킨 모발에 카르보디이미드와 펩타이드 결합을 적용하여 DSC로 구조적 변화와 거칠기 및 인장강도를 확인한 결과, 외인성 요인으로 노화된 모발을 에이징 이전의 상태의 물성 쪽으로 개선시키는 효과를 확인할 수 있었다. 뿐만 아니라 내인성 노화에 의해서 소실 된 내부 구성 성분을 프로폴리스를 이용하여 보강한 경우에도 외인성 노화가 유도된 모발의 물성이 에이징 이전 상태의 물성으로 회복되는 안티 에이징 효능이 발생함을 확인하였다. 본 연구에서 사용한 외인성 노화 유발 모발 시료 및 평가는 모발의 외인성 노화 연구에 유용하게 적용될 수 있음을 최초로 확인하였다.

The purpose of this study was to find out the variables affecting the successful aging of the elderly. To achieve this purpose, a survey was conducted with 388 seniors living in the Jeonbuk area. The data were analyzed using multiple regressions and a path analysis. The major findings were as follows: First, statistically significantly different perception of successful aging was observed according to their marital status. Second, successful aging of the elderly with a spouse was influenced by personal variables, such as their own perception of economic status, gender, education level and physical condition. In contrast, successful aging of the elderly without a spouse was most influenced by social variables, such as family support. Third, the attitude towards aging directly affected successful aging. Various personal and social characteristics indirectly affected successful aging via attitudes towards aging according to the presence of a spouse.

PURPOSE: This study is research about deep trunk muscles (DTM) that is important and serve to control the movement of the trunk to provide stability during movement for human. In this study, trying to prove a change of DTM of aging in the ultrasound image. METHODS: We measured via an ultrasound image during rest and contraction of DTM in 42 young and 48 old people, and then we measured the change of thickness and symmetry. RESULTS: Symmetry showed a significant difference only external oblique (EO) in the young(p<.05). In the elderly, it was found that ratio of contraction was greater transverse abdominis than EO. CONCLUSION: I considered it could lead to improvement of activity of daily life by applying intervention for recovery of motor control of TrA for the elderly in clinical practice.

Human body ages differently due to environmental, genetic and pathological factors. DNA methylation patterns also differs depending on various factors such as aging and several other diseases. The aging clock model, which uses these differences to predict age, analyzes DNA methylation patterns, recognizes age-specific patterns, predicts age, and grasps the speed and degree of aging. Aging occurs in everyone and causes various problems such as deterioration of physical ability and complications. Alzheimer's disease is a disease associated with aging and the most common brain degenerative disease. This disease causes various cognitive functions disabilities such as dementia and impaired judgment to motor functions, making daily life impossible. It has been reported that the incidence and progression of this disease increase with aging, and that increased phosphorylation of Aβ and tau proteins, which are overexpressed in this disease and accelerates epigenetic aging. It has also been reported that DNA methylation is significantly increased in the hippocampus and entorhinal cortex of Alzheimer's disease patients. Therefore, we calculated the biological age using the Epi clock, a pan-tissue aging clock model, and confirmed that the epigenetic age of patients suffering from Alzheimer's disease is lower than their actual age. Also, it was confirmed to slow down aging.
