Purpose: Since skin sparing mastectomy removes the mammary gland and the nipple-areolar complex preserving all mammary skin, it makes the widespread use of implants in immediate reconstruction. This article reports our experience in immediate breast reconstruction after skin sparing mastectomy by using the silicone implants in patients especially who have small to moderate sized and minimal ptotic breast. Methods: From September of 2007 to July of 2009, we performed breast reconstruction for 44 breasts of 40 women with silicone implant after mastectomy. Tumors were divided into 5 malignant types (21 IDC, 18 DCIS, 2 ILC, 2 phylloides tumor, 1 mucinous carcinoma). The implant is placed in a submuscular pocket or in a submuscularsubfascial pocket depending upon the condition of the muscles and skin flaps after mastectomy. Results: The mean age was 47 years and the average follow-up period was 11 months. Cosmetic outcome was assessed by evaluation of photographs and assessment of breast volume and shape, breast symmetry, and overall outcome. About 80% of each of these parameters was scored as good or excellent. Breast complication was developed in a total of 6 cases including 2 capsular contracture, 2 partial skin necrosis due to blue dye injection and 2 implant infection. Conclusion: The use of definitive implants in a skin sparing mastectomy is a one-stage immediate breast reconstruction with low morbidity and acceptable result. This method is considered reliable with favorable aesthetic result.

Purpose - This research aims to investigate the effects that the selection of oriental medicine cosmetics and brand asset attributes have on consumers' economic, emotional and social values in order to shed light on the forms and characteristics of consumption within the globally developing oriental medicine cosmetics market, and in the end positively verify how such perceived values affect purchase intention. In addition, it proposes research outcomes by comparing the differences between national and cultural consumer purchase behavior based on the comparisons of consumer groups in South Korea and China, the major markets for oriental medicine cosmetics. Research design, data, and methodology - Based on advanced research a total of 9 hypotheses were designed and questionnaires consisting of 16 questions to identify six major variables were conducted. Research was carried out centered on Seoul, South Korea, and its surrounding metropolitan area as well as Beijing and Shanghai, China, and a total of 577 sets of significant data were collected. A comparison analysis was then conducted on the data from 285 Koreans and 292 Chinese. A regression analysis and path analysis were also carried out based on a structural equation model to suggest results. Results - Research results show brand value assets had a more crucial impact on consumers' perceived value than consumer selection of oriental medicine cosmetics, while emotional value had a bigger effect on purchase intension than social or economic values. For Chinese consumers in particular, social, economic and emotional values affected purchase intention, while emotional value was the most crucial factor for Korean consumers. Conclusions - With oriental medicine cosmetics, brand characteristics and images that helped express emotional desire proved to be more effective in marketing than the performance aspect of cosmetics, including their functions and ingredients. In the end, products that highlight individual desire and emotion should be introduced instead of those that emphasize price, functions and social characteristics in order to expand the global market of oriental medicine cosmetics.

The cooling rate and the uniformity of mold temperature, in the injection molding process, possess great influences on the productivity and quality of replications. The conformal cooling channel, which is of a uniform spacing from the mold cavity by the metal additive manufacturing process, receives much attention recently. The purpose of this study is to develop a mold core with a curved conformal cooling channel for a pottery-shaped thick-wall cosmetic container through the hybrid method of direct metal tooling (DMT) process. In this study, we design a mold core that contains the curved cooling channel for the container. A method that divides the cavity is proposed and the DMT process is carried out to form the curved cooling channel. The test mold core, with the curved conformal cooling channel, has been fabricated by the proposed method to confirm the feasibility of the design concept. We show that no leakage is observed for the additive manufactured test mold core, and its physical properties demonstrate that it can be sufficiently used as the injection mold core.

Objectives : The purpose of this study is to investigate the effect of Shinsuwisaengtang (SSWST) extracts on antioxidant activity and inhibition of phototoxicity as a medicine for skin damage due to ultra violet stimulation. Methods : To determine the cytotoxicity of Hs68 cells from SSWST extracts, we investigated cell viability by MTT assay. To determine the protective effect of phototoxicity, we investigated cell viability after UVB radiation. The DPPH radical scavenging activity was examined to determine the antioxidant effect of SSWST extracts. Hoechst 33258 staining was performed to observe the protective effect of SSWST on UVB. Results : The cytotoxicity of SSWST extracts in Hs68 cells was not appeared significantly in all concentration. SSWST extracts significantly increased the viability of UVB-stimulated Hs68 cells at a concentration of 25, 50 and $100{\mu}g/ml$. SSWST extract showed higher DPPH radical scavenging than the control group. It was observed that SSWST extracts inhibited the apoptosis of the UVB-stimulated Hs68 cells through a fluorescence microscope. Conclusions : It was observed that SSWST did not induce cytotoxicity at a constant concentration and had a protective effect on phototoxicity and an antioxidant effect. Thus, it is considered that it maybe used as a medicine to cure skin damage caused by UVB and photoaging changes in the future.

Objectives : Inflammation is one of the self-protective abilities against tissue injury, and it has clinical symptoms like redness, heat, swelling, pain, and loss of function. The purpose of this study is to examine inhibitory effects of Naetakchunkeum-san (NTCKS) on nitric oxide (NO), Prostaglandin E2 (PGE2), inducible NOS (iNOS), cyclooxygenase-2 (COX-2), and phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2), which play a major role in inflammatory response. Methods : The experiment was performed using Raw 264.7 cells pretreated with NTCKS extracts. Cell viability was determined by MTT assay. To evaluate anti-inflammatory effects of NTCKS, we examined NO and $PGE_2$ production in LPS-induced macrophages. We also investigated effects of NTCKS on iNOS, Cox-2, and ERK1/2 expression using western blot. Results : In MTT assay, no cytotoxicity of NTCKS (50, 100, 150, $200{\mu}g/ml$) on RAW 264.7 cell was found. LPS-induced NO production was decreased after treatment with NTCKS (150, $200{\mu}g/ml$)(p<0.05). $PGE_2$ was decreased after treatment with NTCKS (150, $200{\mu}g/ml$)(p<0.05). NTCKS inhibited LPS-induced expressions of iNOS and COX-2 in a dose-dependent manner. Increased phosphorylation of ERK1/2 by LPS was decreased by NTCKS in a dose-dependent manner. Conclusions : According to above experiments, NTCKS may be applied to inflammatory diseases such as atopic dermatitis, rheumatoid arthritis, and inflammatory bowel disease.

Purpose: Barely sprout is a well-known oriental herbal medicine with a wide range of health benefits. Recent studies have provided scientific evidence of its therapeutic effects with expanded application. This study investigated anti-melanogenic effect of barley sprout water extract (BSE) in murine melanocyte B16F10. Methods: Various concentrations (0, 50, 125, and $250{\mu}g/mL$) of BSE and arbutin (150 ppm) were applied to B16F10 stimulated with or without alpha-melanocyte stimulating hormone (100 nM) for 72 hours. The whitening potency of BSE was determined altered cellular melanin contents. Activity and expression of tyrosinase and microphthalmia-associated transcription factor (MITF) were also assayed. Results: Experimental results revealed that treatment with BSE reduced cellular melanin production by approximately 40% compared to the control. Molecular findings supported that suppressed activity and expression of tyrosinase and MITF proteins by BSE were associated with declined cellular melanogenesis. Furthermore, anti-melanogenic effect of BSE ($250{\mu}g/mL$) was similar to that of arbutin, a commonly used whitening agent. Lastly, polyphenols including p-coumaric, ferulic, and vanillic acids were identified in BSE using HPLC analyses. They might be potential active ingredients showing such melanogenesis-reducing effect. Conclusion: BSE was evident to possess favorable anti-melanogenic potency in an in vitro model. As a natural food sourced material, BSE could be an effective depigmentation agent with potential application in pharmaceutical and cosmetic industries.
