Collagen peptide plays a protective role in skin by increasing the activity of antioxidant, acts like an activator of skin regeneration by positive feedback and is used as a potent candidate for cosmetics or functional food. GABA acts at inhibitory synapses in the brain by binding to specific transmembrane receptors of both pre- and postsynaptic neuronal processes in vertebrates, is also involved in the synthesis of melatonin and might exert regulatory effects on sleep and reproductive functions. In this study, we investigated the beneficial effect of a mixture of collagen peptide and GABA (J85091900) on skin and sleep condition in woman experiencing sleep disorder. We found that oral supplement with J85091900 significantly decreased the value of Pittsburgh Sleep Quality Index (PSQI), increased sleeping time by 7%, and also improved skin roughness (Ra, Rz, Rt), periorbital wrinkle (Ra, Rt), and skin capacitance in human. These findings indicate that dual strategy with which skin improvement is accomplished using collagen peptide and sleeping well is acquired using GABA could be the novel solution for sleeping beauty by edible cosmetics to improve skin status.

With the increasing number of skin care shops, service quality development that can meet the customer needs is needed to obtain differentiated competitive advantage. Accordingly this study was attempted to provide basic data on marketing necessary for operating a skin care shop by identifying the impact of service quality on perceived reciprocity and long-term relationship orientation among the customers using a skin care shop. This study conducted a survey of 290 female customers using skin care shops located in Seoul and Gyeonggi province, Jeollanamdo and Jeollabukdo, and Gyeongsangnamdo and Gyeongsangbukdo through personal visit, e-mail, and post service, and the collected data were analyzed with SPSS Ver. 18.0 and Amos Ver. 18.0. As a result, it was proven that overall goodness-of-fit to the theoretical model of the research hypotheses set in this study is good. In Hypothesis 1, "Skin care specialist's work ability, facility and sanitation, and care products had a significant positive (+) impact on perceived reciprocity," which was partially adopted. In Hypothesis 2, "Skin care specialist's work ability, care products, and devices and tools had a significant positive (+) impact on long-term relationship orientation," which was adopted. In Hypothesis 3, "Perceived reciprocity had a significant positive (+) impact on long-term relationship orientation," which was adopted. Therefore, it can be concluded that skin care specialist's work ability, facility and sanitation, care products, and devices and tools are the service quality elements for allowing customers to feel thankful or encouraging them to visit the skin care shops continuously.

This study is aimed at identifying the important factors required by customers through importance-satisfaction analysis of how they choose skin care shops on the basis of certain factors and attributes at this time when there is an urgent need to improve the level of quality that meets their expectations and demands in combination with the quantitative expansion of skin care shops. To achieve this, a survey was carried out to 217 people over the age of 20 in Gwangju and Jeonnam area with experience in using skin care shop services. The SPSS v. 21.0 program was used to analyze the collected data. The results are summarized as follows. IPA grid analysis of the difference in importance-satisfaction of sub-factors for skin care shop choice showed that the items corresponding to the upper-left side of maintenance and strengthening, the upper-right side of stainability, and the lower-left side of gradual improvement were the 'sanitary control of tools and products', 'basic situation(legal compliance)', and 'workers' sanitary control', 'internal control of skin care shops', 'professionalism and skills of workers'and 'quality of services', respectively. Consequently, the results of this study will be based on the efficient operation of skin care shops, and further more the utilization of them is expected to expand the quantitative and qualitative base of the skin care industry.

Most of Korea's beauty college education focuses on the subject rather than the industrial field of the industrialized world. It is centered on subjects rather than on-site job modules, and training sessions are required for graduation of the training period rather than having flexible configurations. Therefore, the education curriculum and industrial field training are becoming mismatched because of the goal of acquiring a certificate in skin care major subjects. Based on this problem, the researcher made a questionnaire about the certificate utilization of students who are majoring in skin care and 294 students were surveyed. It was found that it had a high degree of utilization to take a job, but that it had below normal level on utilization after entering the industrial field. Based on this analysis result, I propose to review the need to reorganize the skin care curriculum, which is based on the national competency standards (NCS) beginning in 2014. Education experts at the college of skin care should continue to develop a curriculum centered on academic subjects and industrial field curriculum as closely as possible, by focusing on the direction and trend of the industry's branches and industry experts.

This study was performed to analyze the relationship among sebum hydration content of the skin and nutritional intake, serum antioxidant minerals and antioxidant enzymes, and lipid peroxide concentration in 50 female subjects in their 20s. The skin type was divided into Dry Skin, Mixed Skin, and Oily Skin, and the dry skin group was 14%, the mixed skin group was 56%, and the oily skin group was 30% of all subjects. The average age of the subjects was $20.54{\pm}1.43$ years and BMI was 20.66. The average sebum content in each group was in the order of T-zone>forehead>chin>cheek. In case of the T-zone, a significant difference between the dry skin group and the oily skin group was observed, suggesting that the area is most sensitive to sebum content by skin type. Significant differences were not observed in energy and nutrient intakes by skin type. Serum concentrations of antioxidant minerals such as copper, manganese, zinc and selenium were not significantly different among the groups, but the dry skin group tended to be higher than the oily skin group. Serum catalase was significantly higher in the oily skin group (P < 0.05), and MDA was significantly higher in the mixed skin group (P < 0.05). The hydration of the cheek and serum zinc showed a negative correlation, and the sebum content of the cheek and GPx showed a significant negative correlation. The hydration of the forehead and serum copper showed a significant negative correlation, and the hydration of the forehead and GPx showed a significant positive correlation. The hydration of the chin and serum SOD showed a significant positive correlation. With these results, it is considered that the basic condition of nutritional status can affect the skin health.
