Unlike the past, the elderly who are growing rapidly in Korea are called 'active seniors'. They prefer to live in urban silver towns despite high living cost and make their own new urban contents. The new urban contents that reflect the living characteristics of active seniors have an important impact on their choice of residential location. Therefore, the purpose of this study is to identify the location characteristics of urban silver towns, which are preferred as the main residence of active seniors, based on the urban living contents of active seniors. The location characteristics of urban silver towns considering the urban living contents of active seniors can be classified 1) public transportation, 2) nearby arterial roads, 3) culture shopping facilities, 4) medical facilities, 5) apartment complexes, and 6) natural environments. Especially, the accessibilities of medical facilities, apartment complexes, and culture shopping facilities were the main characteristics of urban silver towns. The results of this study are expected to be helpful not only the location of urban silver towns, which is the urban new content of active senior, but also for the policy on housing for the elderly.

In this study, we investigated the anti-aging effect of Rosa damascena extract containing low molecular glycoprotein (RELG) converted from the high molecular glycoprotein by bioconversion. Free radical scavenging activities were performed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Antioxidant activities ($IC_{50}$) of RELG and the positive control ascorbic acid were $22.6{\mu}g/mL$ and $21.1{\mu}g/mL$, respectively. For skin cells, $15{\mu}g/mL$ RELG showed 28% antioxidant activity by inhibiting the production of active oxygen species induced by ultraviolet ray and hydrogen peroxide. $15{\mu}g/mL$ RELG prevented 10% the cell death caused by stress in human hair follicle dermal papilla cells (HDPC) and reduced 90% the production of active oxygen species. In addition, the glycoprotein showed not only anti-wrinkle effect but also moisturizing effect by 48% inhibition of matrix metallo proteinase-1 (MMP-1) production by ultraviolet stress and $10{\mu}g/mL$ RELG enhanced 10% neutral lipid synthesis with 44% aquaporin 3 (AQP3) expression, which is moisture factor. In conclusion, the RELG can be used as an anti-aging cosmetic material.

The purpose of this study was to evaluate and verify the effectiveness of sustainable cosmetic raw materials developed from Gynostemma pentaphyllum, a plant native to Ulleungdo, in improving the skin barrier function and treating atopic dermatitis. Cells were derived from adult Gynostemma pentaphyllum plants, and suitable conditions for mass culture of the cells were established in a bioreactor. DNA components and amino acids extracted from this mass culture were identified from the HPLC fraction. In the in vitro efficacy evaluation results, changes in the expression levels of skin barrier-related proteins such as filaggrin (FLG) and Zonula occludens-1 (Zo-1) were insignificant. It was confirmed that the expression levels of the proteins thymic stromal lymphopoietin (TSLP) and interleukin-33 (IL-33) were significantly reduced. These results lead to the conclusion that Gynostemma pentaphyllum cell extracts have significant anti-inflammatory effects and that these extracts can be widely used as sustainable, nature-friendly active material in cosmetics with anti-inflammatory effects and targeted at improving atopic dermatitis.They may find use in anti-aging cosmetic products as well.

The numbers of the elderly who suffer Empty Nest Syndrome have been accelerated as an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing houses into shared houses was set as a hypothetical solution in this study, and finding out the responses of the elderly who owns their own houses is the purpose of the study. A small workshop panel method was used and the elderly aged 55 years upwards took part and they own a detached house that is relatively large for the elderly or the elderly couple to live alone. The workshop was consisted of 3 stages: 1. a survey 2. an interview 3. a site visit. Through this, problems that the elderly have been experiencing within their houses were looked into and the responses of the elderly on converting their houses to shared houses by introducing developed schematic plans. As a result, positive responses from the house owners were carried out based on the fact that subsidies from the government on house renovation and tenants matching programs are supported. Shared houses could provide home owners economical support with rents and help them to feel less lonely. This is one way of supporting the elderly to live and age actively in their later lives. Therefore, this idea should be established in connection with preparing aging, aged, and super-aged society.

Leukemia inhibitory factor (LIF) is a member of the IL-6 cytokine family, having pleiotropic actions such as maintaining stem cell pluripotency and enabling blastocyst implantation. Because the action of LIF is mediated by a ligand-receptor interaction with the LIF receptor (LIF-R), an antagonist for LIF-R has been developed to inhibit LIF-induced signaling. In this study, we present a novel method for the production and purification of an antagonist to human LIF-R (hLA). His-tagged hLA was expressed in E. coli, and simple purification methods without any endopeptidase cleavage were designed. In addition, we determined the optimal temperature conditions for enhancing the production of soluble hLA. Finally, the bioactivity of His-tagged hLA was examined using STAT3 phosphorylation and receptivity of human endometrial ECC-1 cells. Our strategy provides a rapid and efficient method to produce biologically active recombinant hLA.

Background: Immunoregulatory elements have emerged as useful immunotherapeutic agents against cancer. In traditional medicine, Mori folium, the leaf of Morus alba L. (Moraceae), has been used for various medicinal purposes; however, the immunomodulatory effects have not been fully identified. We evaluated the immunoenhancing potential of water extract of Mori folium (WEMF) in murine RAW264.7 macrophages. Methods: RAW264.7 cells were treated with WEMF for 24 hours and cell viability was detected by an MTT method. Nitric oxide (NO) levels in the culture supernatants were assayed using Griess reagent. The productions of prostaglandin $E_2$ ($PGE_2$) and immune-related cytokines was measured using ELISA detection kits. The mRNA and protein expression levels of Inducible NO synthase, COX-2, and cytokines were assayed by reverse transcription-PCR and Western blotting, respectively. The effect of WEMF on phagocytic activity was measured using a Phagocytosis Assay Kit. Results: WEMF significantly stimulated the production of NO and $PGE_2$ as immune response parameters at noncytotoxic concentrations, which was associated with the increased expression of inducible NO synthase and COX-2. The release and expression of cytokines, such as $TNF-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-6, and IL-10, were also significantly increased in response to treatment with WEMF. Moreover, WEMF promoted the macrophagic differentiation of RAW264.7 cells and the resulting phagocytosis activity. Conclusions: WEMF has the potential to modulate the immune function by regulating immunological parameters. Further studies are needed to identify the active compounds and to support the use of WEMF as an immune stimulant.

The purpose of this study is to review Saeromaji Plan 2015 (the Second Basic Plan for the Low Fertility and Aging Society) with the framework of WHO's (2007) guidelines for building age-friendly cities and to provide suggestions for improvements in planning for the aging society. The contents of the Plan pertaining to the aging society sections were reviewed by two independent researchers to examine the extent to which the Plan fulfilled 169 checklists across 8 themes proposed by WHO. The results indicate that all 8 themes were partially reflected in the Plan. Suggested improvements for planning for the aging society include taking an inclusive approach to bring generations together, providing more options for older adults, and including more active involvement of the private sector in planning.

As an aging population is increasing, more elderly people are exposed to traumatic stress. Although this issue has received more attention in some literature, it is clear that numerous questions exist in aftermath of trauma exposure in elderly people. In case of Korean elderly suffers, traumatic experience includes the Korean war, military dictatorship and violent demonstration. Studies regarding elderly PTSD is not active and a lot of patients are not still engaged in treatment. We suggest that concerns that are unique to this population are necessary.
