Anti-aging is one of the key words to have characterized Korean society, and Korean adults in their 40s and 50s are very interested in this word. In this study, their cognitive ages and body images which are expected to have been influenced by anti-ageing were determined and correlation between them was examined. A survey was conducted and 368 of 500 questionnaires were used in data analysis. Data were analyzed by descriptives, factor analysis, reliability analysis, correlation analysis, and multiple response analysis through SPSS 12.0. The results are as follows. First, the cognitive ages of Korean adults in their 40s and 50s showed to be 37.5 years old which are 9.1 years old younger than their average actual ages. Second, their attitudinal body images appeared to be composed of appearance orientation and appearance evaluation, and appearance orientation represented to be a little higher than appearance evaluation. In addition, it showed that the correlation between cognitive ages and the attitudinal body images was low and negative. Third, people in their 40s and 50s revealed to think good health and impression as ideal body images. It was found that they regarded a face as the most important body part for ideal body images and were sensitive of their weight. Forth, correlation between cognitive ages and variables of ideal body images was identified to be significant in 4 variables which are slender, shapely and slim figure and good body proportions. In conclusion, it was shown that Korean adults in their 40s and 50s recognized themselves to be 9.1 years old younger and, the younger they perceive themselves, the younger body images they want. Also, it could be confirmed that anti-ageing is a megatrend in Korean society.

An assumption for fractional ages should be made to obtain the net premium of the whole life insurance payable at the moment of death based on the life table. Most existing studies adopt the assumption of the uniform distribution(UDD) for the fractional ages. However, as seasonal changes may frequently lead to the deaths of elderly people, it is questionable whether the assumption of the uniform distribution is the most appropriate one for the entire age intervals. In this article, based on a real mortality data set, the appropriateness of UDD assumption for the entire age intervals is examined. And then we propose a more suitable model for fractional ages. We analyze the effect of UDD assumption through the net premium and the corresponding risk when the true distribution for the fractional ages is not uniform.

Advanced glycation end products (AGEs) have been postulated to play a central role in the development of diabetic complications. A variety of different agents that inhibit AGEs have been under investigation. In this study, 62 herbal medicines from China and Vietnam have been investigated with an in vitro evaluation system using AGEs formation inhibitory activity. Of these, 5 herbal medicines ($IC_{50}$ < $5{\mu}g/ml$) were found to have significant AGEs formation inhibitory activity. Particularly, herbal medicines Albizia odoratissima (twigs and leaves), Rhododendron spinuliferum (twigs and leaves), Dioscorea cirrhosa (stems and leaves), Illicium verum (stems and leaves) and Aglaia perviridis (stems and leaves), showed more potent inhibitory activity (approximately 16-26 fold) than the positive control aminoguanidine ($IC_{50}=76.47{\mu}g/ml$).

Objectives: This study was conducted in order to determine how the association between socioeconomic position(SEP) and health status changes with age among Seoul residents aged 25 and over. Methods: We utilized the 2001 and 2005 Seoul Citizens Health Indicators Surveys. We used self-rated 'poor' health status as an outcome variable, and family income as an indicator of SEP. In order to characterize the differential effects of socioeconomic position on health by age, we conducted separate multivariate analyses by 10-year age groups, controlling for sociodemographic covariates. In order to assess the relative health inequality across socioeconomic groups, we estimated the Relative Index of Inequality (RII). Results: The risk of 'poor health' is significantly high in low family income groups, and this increased risk is seen at all ages. However, the magnitude of relative socioeconomic inequality in health, as measured by the odds ratio and RII, is not identical across age groups. The difference in health across income groups is small in early adulthood (ages 25-34), but increases with age until relatively late in life (ages 35-64). It then decreases among the elderly population (ages more than 65). When the RII reported in 2005 is compared to that reported in 2001, RII can be seen to have increased across all ages, with the exception of individuals aged 25-34. Conclusions: The magnitude of health inequality is the greatest during mid- to late adulthood (ages 45-64). In addition, health inequalities have worsened between 2001 and 2005 across all age groups after economic crisis.

Objectives: This study examined whether Lycii Radicis Cortex has an inhibitory effect on inflammatory response through an oxidative stress and advanced glycation endproducts (AGEs)-mediated pathway in streptozotocin (STZ)-induced type 1 diabetic rats. Methods: Lycii Radicis Cortex was orally administered to STZ-induced diabetic rats in doses of 80 or 160 mg/kg body weight/day for 2 weeks, and its effects were compared with those of diabetic control and normal rats. Results: The administration of Lycii Radicis Cortex decreased the elevated serum urea nitrogen and renal reactive oxygen species (ROS), and reduced the increased AGEs in the serum and kidney. The elevated protein expressions of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunits in the kidney of diabetic control rats were significantly decreased after Lycii Radicis Cortex treatments. Moreover, the kidney of diabetic rats exhibited the up-regulation of receptor for AGEs (RAGE) and AGEs-related proteins; however, Lycii Radicis Cortex treatment also significantly reduced those expressions (excepted RAGE). In addition, the diabetic rats exhibited an up-regulation of the expression of proteins related to inflammation in the kidney, but Lycii Radicis Cortex administration reduced significantly the expression of the inflammatory proteins through the nuclear factor-kappa B (NF-${\kappa}B$) and activator protein-1 (AP-1) pathways. Conclusions: This study provides scientific evidence that Lycii Radicis Cortex exerts the antidiabetic effect by inhibiting the expressions of AGEs and NF-${\kappa}B$ in the STZ-induced diabetic rats.

Objectives : Corni Fructus (CF) is traditional herbal medicine used on polyuria, low back pain, and tinnitus. This study aimed to evaluate inhibits skin wrinkle formation effect of CF. Methods : To evaluate the produce inhibition effect of CF, SD-rats were distributed into four groups; normal rats (Nor), AGEs (advenced glycation end product)-induced rats (Con), AGEs-induced rats treated with 100mg/kg CF (CF). To induce AGEs, streptozotocin (50mg/kg) was administered intraperitoneally and after 3 days oral administrated 100mM methyl glyoxal for 3 weeks. Results : The oral administration of CF suppressed the reactive oxygen specis (ROS) in serum. The AGEs in skin tissues was significantly reduced through treatment of CF. Furthermore, the expressions of AGEs related proteins such as polyclonal anti-$N^e$-(carboxymethyl)lysine (CML), anti-$N^e$-(carboxyethyl)lysine (CEL), AGE receptors (RAGE) were decreased in CF treated group compared with the control group in skin tissues. Inflammation-related proteins such as Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), monocyte chemoattractant protein-1 (MCP-1), interleukin-6 (IL-6) reduced in CF treatment group than control group. AGE-induced rats exhibited that the significant decreased collagen however, CF treatment (100mg/kg of body weight) up regulated collagen by improved the expression levels of skin fibril-related genes such as Matrix metalloproteinase (MMP-1). Conclusion : Taken together, our study suggests that CF regulates ROS to prevent accumulation of AGEs and inhibits skin wrinkles. Our finding indicate that CF may be an effective agent for inhibits AGEs formation, and improved skin wrinkle.
