Peroxynitrite, formed from the reaction of .O2- and .NO, is a cytotoxic species that can oxidize several cellular components such as proteins. lipids and DNA. Oxidative stress is considered to be the major cause of aging and many age-related diseases including Alzheimer's disease. rheumatoid arthritis. cancer. and atherosclerosis. ONO-, a powerful oxidant, can cause damage of proteins, lipid and DNA through nitration and oxidation. (omitted)

With using the 4th and 5th wave of KLoSA(Korean Longitudinal Study of Aging), this study analyzed the effect of the factors of Rowe and Kahn's successful aging model on the life satisfaction of older adults. The target population of this study was 1,385 who is older than 65. As data analysis, hierarchical multiple regression was used. The variables such as demographics, avoiding diseases and disability, high cognitive and physical function and engagement with life, relationship with adult children were entered hierarchically for the regression analysis. Since there are differences of longevity by gender, the difference of factors of successful aging were compared by marital status. In this study (besides Rowe and Kahn's successful aging model such as avoiding disease and disability, high cognitive and physical function, and engagement with life), the relationships with adult children were analyzed additionally. Findings show that married older adults were older and reside with their adult children twice more than those who do not have a spouse. According to research results, regular exercise and memory skills were important factors of affecting life satisfaction. Among the categories of active engagement, meeting with friends, relatives and neighbors were significant. Contact with their adult children by mail or phone were the most important factors affecting the older adults' life satisfaction. The three parts of successful aging were various depending on the operationalization of variables.

As Korea became the aged society, people pay more attention to their health and disease prevention. For a better and healthy aging, it is even more important for active seniors to manage their health. The development of functional ingredients targeted for active seniors, which may improve cardiovascular and menopausal women's health, and their certification as individually recognized functional materials could serve as a new growth engine for the functional foods industry as well as contribute to the improvement of public health.

Osteoarthritis is to the abnormality of the inflammatory response of joint tissue caused by various causes such as aging, and muscle loss. In this study, the activity in joint inflammation was verified using SKBE, a plant extract, and the expression levels of arthritis-inducing proteins including MMP-1, MMP-3, MMP-13, and collagen type II in vitro were compared and analyzed. Furthermore, we synthesized α-spinasterol, an active ingredient of SKBE, by the previously reported synthesis method and these findings could provide a new starting point for the development of treatments for osteoarthritis.

This study was conducted to offer basic data that can be used in a clothing industry for active senior males that are emerging as a new consumer bracket in a rapid aging age. To this end, this study conducted an analysis of 'younger' older male body types based on data from the 6th Size Korea. As a result of the body type analysis of 'younger' older males who are considered active seniors in comparison to 'middle' aged males, the former's height items became shorter compared to 'middle' aged males, but circumference items were bigger. Males aged 35-69, who are 'middle' aged males and 'younger' old males were divided into three body types in this study: Type1- small body type with protruded belly, compared to weight. Type 2- body type of slim torso with wide shoulder-back widths. Type3- big body type overall with tall height and heavy weight. According to body type distribution by age group, the middle-aged males had Type2 body type the most. The younger-old males showed type1 the most. There is a need to reflect the body types of active senior male characteristics in apparel pattern design because the current fits are not appropriate if active senior males wear clothing targeted for males aged 30-50.

In recent years the combination of IT and BT for U-Healthcare Medical Services has attracted popular attention as an alternative for solving health problems due to aging issue. Active oxygen as free radicals causes unstable state of the body resulting to other disease on which approximate 90% of the diseases are associated with active oxygen. The severity is even higher along with increasing age. Therefore, there is a need for systematic management of active oxygen saturation for the elderly and chronic patients. In this paper, the data about active oxygen measurements from the body measurement is sent to the data storage of medical facilities by the service provider. Medical information is measured by devices provided complying with the standard, support and information using Bluetooth communication. Users can check their health status themselves using the proposed system through 3G/4G mobile devices like smart phone to medical institutions in which the smart phone act as a gateway for medical data transferred from patient to medical institutions and vice versa. Users can get and experience a diagnosis and effective U-Environmental Health Services from Medical institutions anywhere using the proposed built system.

This study was carried out to offer basic data that can be used for the production of outdoor pants for active senior males, which is emerging as a new consumer bracket in the rapidly aging society. To this end, this study modified and complemented the patterns of existing outdoor pants for active senior males, that received the most positive evaluations. On the basis of the research and outdoor wear assessment results, this study proposed the matters to consider in the manufacturing of outdoor pants for active senior males. As a result of the existing outdoor wear's wearing assessment, the pants of brand C were revealed to be the best. This study actually designed research outdoor wear by modifying the problematic parts by adding and subtracting spare length or circumference, on parts where fit satisfaction was low, and by referring to the selected brands' patterns. The research outdoor pants were designed by referring to the preferred outdoor types and colors that were revealed in the survey results. The wearing assessment was conducted by comparing the manufactured research outdoor pants and the existing outdoor pants, which were selected as the best outdoor pants. Consequently, this study verified the fit of the research outdoor pants was superior to most items. This study proposed the final patterns of outdoor pants suitable for active senior males through the modification of several items that required some improvements revealed via the wearing assessment of the research outdoor.

This study aimed to examine whether there was difference on visual fatigue between active seniors and young people, and to provide a guideline for appropriate computer use time for seniors. Blinking rate, maximal blinking interval, temperature of the ocular surface, visual fatigue questionnare were evaluated. The blinking rate, ocular surface temperature, visual fatigue showed significant change before and after the tasks. There was no difference between the two groups and thus, about 30-minute computer work appeared to be appropriate for seniors.

Rhamnose-rich (RROP-s) and fucose-rich (FROP-s) oligo-and polysaccharides were prepared and extensively characterised by physical and chemical procedures [1,2] and compared to L-fucose. Their biological properties were then studied on human skin fibroblast cell cultures, human skin explant cultures and on hairless rat skin, using a variety of cell-biological, biochemical and computerised morphometrical procedures. Among the most important properties we could establish, the following are of particular interest for the tretment and prevention of age-dependent modifications of human skin (loss of skin-tissue, cells and matrix, wrinkle formation and others) : stimulation of cell proliferation (by $^3$[H]-thymidine incorporation and the MTT test), scavenging of reactive oxygen species (ROS) using several different procedures, and protease (MMP-2 and MMP-9) down-regulation. A topical preparation, using RROP-s and FROP-s, and/or L-fucose, was shown to increase cell proliferation, dermal matrix synthesis, efficient scavenging of ROS-s and to increase also the thickness of dermal tissue when applied for 4 weeks on hairless rat skin, accompanied by the densification of collagen bundles as well as by an increase of elastin synthesis. Using fluorescent labeled FROPs, it could be shown that these oligosaccharides react with cell-membrane receptors and especially with the elastin-laminin-receptor and the fucose-mannose receptor, but they penetrate also in the cell nucleus, suggesting the possibility of a direct action on the regulation of gene expression. When applied to the human skin of a team of voluntary women encompassing all age-groups, the efficiency of FROP-containing preparation could be confirmed using indentometry and computerised evaluation of skin micro-relief, as well as evaluation of periorbital wrinkles. It appears therefore that these preparations correspond to all the requirements of active anti-aging principles.
