나이가 들어감에 따라 눈에 띄게 변화를 일으키는 곳이 피부이다. 따라서 여성이라면 누구나 나이가 들어도 변함없이 젊고 싱싱한 피부를 원하는 마음을 갖고 있을 것이다. 노화를 방지하여 변함없이 건강하고 젊은 피부를 유지하는 데는 크게 두 가지 방법이 있다. 첫째 내적으로 노화 방지를 위한 건강관리로 식사요법과 운동요법 등이 있으며 둘째는 피부 자체를 다듬고 관리 해주는 방법이다.

유난스러웠던 꽃샘추위 때문에 힘들었던 시간이 지나고 햇살이 따스한 것이 어느새 봄은 한 걸음 더 우리에게 다가와 있다. 덕분에 움츠러들었던 몸도 풀리고 기분도 상쾌해지고 있지만, 기온 변화와 공기의 상태에 민감한 우리 호흡기는 제 리듬을 찾지 못하고 힘겨워하기 일쑤다. 노인들의 경우에는 면역력이 저하되고 있고, 호흡기 자체에도 노화가 오기 때문에 계절이 바뀌는 요즘 같은 환절기에는 특히 건강을 잘 챙겨야 한다.

The purpose of this research is to critically analysis the applying trend of the successful aging research on the baby boomers Generation. Research method is qualitative content analysis and this study was analyzed by concepts, factors, heterogeneity and variety of generation. The results of the analysis on 124 domestic articles on the journals on the successful aging from 2000 to 2016 are as follows: most of concepts in researches are about economic problems. In a research model, social environmental factors are barely considered. Heterogeneity and a few studies showed identities and varieties of generation. Based on these results, several suggestions are presented; First, consideration about the concepts of successful aging On a broad range is required. Secondly, concepts and influence factors should be clearly identified. Third, factors related to life itself in aging and macro social environment than factors of individual unit focused on economic value should be used. In addition, new age-old cultual value should be discussed to understand the Inherent traits of baby boomers. Lastly, studies to discuss varieties which are caused by age and gender of the baby boomers are needs to proceed.

대부분의 당뇨병성 합병증은 혈관을 매개로 진행되며, 당뇨병성 혈관질환은 당뇨병환자의 가장 흔한 사망 원인이다. 당뇨병의 관리가 개선되면서 당뇨병환자의 평균수명은 크게 늘어났는데, 혈관질환의 발생 위험성은 시간이 지나면서 자연적인 노화현상과 함께 점점 더 커지므로, 제대로 된 당뇨병의 관리는 혈당 조절 그 자체뿐 아니라 혈관의 손상을 억제하는 노력이 반드시 포함되어야 한다.

Mesenchymal stem cells (MSCs) are characterized by their multipotency capacity, which allows them to differentiate into diverse cell types (bone, cartilage, fat, tendon, and neuron-like cells) and secrete a variety of trophic factors (ANG, FGF-2, HGF, IGF-1, PIGF, SDF-1α, TGF-β, and VEGF). MSCs can be easily isolated from human bone-marrow, fat, and umbilical-cord tissues. These features indicate that MSCs might be of use in stem-cell therapy. However, MSCs undergo cellular senescence during long-term expansion, and this is accompanied by functional declines in stem-cell potency. In the human body, because of their senescence and declines in their microenvironmental niches stem cells fail to maintain tissue homeostasis, and as a result, senescent cells accumulate in tissues. This can lead to age-related diseases, including degenerative disorders and cancers. Recent studies suggest that the number of histone modifications to stem cells’ genomes and aberrant alterations to their DNA methylation increase as stem cells progress into senescence. These epigenetic alterations have been partly reversed with treatments in which DNA methyltransferase (DNMT) inhibitors or histone deacetylase (HDAC) inhibitors are introduced into replicative senescent-MSCs. This review focuses on epigenetic alteration in replicative senescent-MSCs and explains how epigenetic modifications are widely associated with stem-cell senescences such as differentiation, proliferation, migration, calcium signaling, and apoptosis.

The purpose of this study were to identify factors of successful aging and to suggest a successful aging model of elderly using Rowe & Kahn's model of successful aging. The components of the factors consisted of healthful status, physical·cognitive functions, psychosocial characteristics and productive activities. Data were collected from 2,958 elderly who has spouse and aged 65 above in KOSA Panel. Data were analyzed by Amos program 7.0 version. The statistical techniques were used descriptive statistics χ² and covariance structural analysis. Major findings of this study were as follows; Healthful status were positively related to increasing effort on physical·cognitive functions as well as psychosocial characteristics. Physical·cognitive functions were positively and directly related to psychosocial characteristics and productive activities. Psychosocial characteristics were positively and directly related to productive activities. Physical·cognitive functions and psychosocial characteristics were increased by receiving a direct and positive effort from healthful status. Productive activities were increased by receiving a direct and positive effort from physical·cognitive functions and psychosocial characteristics. Specific and realistic measures should be prepared for successful aging not only for present elderly but also for the future elderly people. Further research should be continued and encouraged to improve the implications for the successful aging especially in korea.

원예 생산물은 수확한 후에도 호흡 등의 생명현상을 지속한다. 즉, 원예 생산물의 수확 후 생명현상의 유지를 위한 주된 생리 및 생화학적 변화는 호흡의 증가, 에틸렌 합성 및 작용, 세포벽 붕괴에 의한 조직의 연화, 색소의 파괴 및 합성, 당과 유기산의 함량 변화, 방향물질의 생산 등이 있다. 이와 같이 수확된 원예 생산물은 영양분의 공급이 중단되어 자체내의 저장 양분을 기질로 소모함으로써 품질의 변화를 가져온다. 또한, 원예 생산물은 수확 시기에 에틸렌이 많이 발생하여 숙성과 노화가 촉진된다.(중략)

차의 풍미의 차이는 차잎 자체가 가자고 있는 화학성분 조성의 차이와 가공방법의 차이에 기인하고, 차잎의 화학성분은 차나무의 훔종, 토질, 기후, 재배기술과 시비 등에도 영향을 받는다. 차의 특유한 맛의 주성분은 주로 카테킨과 아미노산류이다. 단맛과 감칠맛은 주로 아미노산 때문이지만 당류도 어느 정도 기여한다. 카테킨류에 의한 최근의 연구결과를 보면 노화를 방지하는 1)항산화 작용 2) 항종양, 발암 억제작용 3) 콜레스테롤 량의 조정 4)고혈압과 혈당 강하작용 5)항균작용과 해독작용이 있다.

1. 밀가루 반죽 내에서 유지류는 gluten의 수화를 감소시키고 따라서 glu1en의 망상 구조형성을 방해함으로써 연화작용을 하게 된다. 이 결과 pastry와 biscuit, cracker 류의 crispness를 증가시키고, shortened cake에 tenderness를 부여한다.2. 유지류의 shortening power는 가소성이 커서 밀가루에 잘 분산될수록, 유지의 사용량이 많을수록, 반죽 정도가 적당할 대, 반죽을 섞는 과정에서 액체 성분 첨가 후의 젓는 정도가 적을수록 커진다. 3. Yeast-raised baked food에서 shortening등 유지류의 역할은 빵의 용적, 탄성 및 기계적 내성을 증가시키고 노화를 지연시키며 질감을 좋게한다. 이러한 shortening의 기능은 밀가루 자체의 지방질과도 밀접한 상관 관계가 있다.

There are many studies on the health and protection of Old-growth and Giant Trees, concentrating on empirical judgment and basic protection measures. The problem this study addresses is the relative importance and priority of the health evaluation indicators of Old-growth and Giant Trees. Firstly, this study exports the evaluation indicators of Old-growth and Giant Trees. The evaluation system for the degree of danger of Old-growth and Giant Trees are composed of two layers: 5 fields and 46 indicators. Secondly, using the AHP and PCA method can determine the weight of each field and each index factor. The process of AHP establishes the relative importance judgment matrix of each field and fully proves that the main cause of danger is individual aging. The PCA method suggested that trunk rot status, light conditions, tree surgeries, bacterial diseases, and soil moisture level are the most important factors in each field. These aspects should be given priority in the management and protection of Old-growth and Giant Trees. Weight values obtained in this study seemed to be useful in the evaluation of Old-growth and Giant Trees.
