In this paper, we propose a prediction system for skin pore labeling based on a CNN(Convolution Neural Network) model, where a data set is constructed by processing skin images taken by users, and a pore feature image is generated by the proposed image processing algorithm. The skin image data set was labeled for pore characteristics based on the visual classification criteria of skin beauty experts. The proposed image processing algorithm was applied to generate pore feature images from skin images and to train a CNN model that predicts pore feature ratings. The prediction results with pore features by the proposed CNN model is similar to experts visual classification results, where less learning time and higher prediction results were obtained than the results by the comparison model (Resnet-50). In this paper, we describe the proposed image processing algorithm and CNN model, the results of the prediction system and future research plans.

Everyone has the desire to be well shaped. Modern people in the $21^{st}$ century utilize their external appearance as a tool to express their personalities and social activities for the improvement of cultural life and the acceleration of information transfer. The expression of beauty is a method of communication from the view point of creation in addition to the exchange of meaning & value, and it has become a method of image transfer due to the increased desire for a better appearance. The beauty industry was established in 1948 by the execution of the 1st hairdresser's license test, and has been developed in full scale through the enactment of the public health control act. Therefore, beauty education is currently qualitatively and quantitatively developed, and the educational role of the beauty institute has expanded to include training beauty professionals. Private beauty institutes provide students with beauty related education in preparation for the national technical qualification examinations or private beauty association tests. These beauty education opportunities enable aspiring beauticians to attend various beauty competition events and acquire a sense of accomplishment. The purpose of this study was to determine how the quality of the beauty educational institutes affects the re-registration rate, and to analyze the effect of the beauty educational institutes quality on the intention of re-registrations using a survey. The study results show that variables such as 'lecture satisfaction', 'internal environment satisfaction', 'facility satisfaction', and 'tuition satisfaction' are significantly related to the rate of re-registrations, with 'lectures satisfaction' especially having the largest influence on re-registration.

In this paper, we suggest a query optimization algorithm to select the optimal processing method of an extended boolean query on inverted files. There can be a lot of methods for processing an extended boolean query according to the processing sequence oh the keywords con tamed in the query, In this sense, the problem of optimizing an extended boolean query it essentially that of optimizing the keyword sequence in the query. In this paper, we show that the problem is basically analogous to the problem of finding the optimal join order in database query optimization, and apply the ideas in the area to the problem solving. We establish the cost model for processing an extended boolean query and develop an algorithm to filled the optimal keyword-processing sequence based on the concept of keyword rank using the keyword selectivity and the access costs of inverted file. We prove that the method selected by the optimization algorithm is really optimum, and show, through experiments, that the optimal method is superior to the others in performance We believe that the suggested optimization algorithm will contribute to the significant enhancement of the information retrieval performance.

This paper presents an automatic text summarization model which selects representative sentences from sentence clusters to create a summary. Summary generation experiments were performed on two sets of test documents after learning the optimum environment from a training set. Centroid clustering method turned out to be the most effective in clustering sentences, and sentence weight was found more effective than the similarity value between sentence and cluster centroid vectors in selecting a representative sentence from each cluster. The result of experiments also proves that inverse sentence weight as well as title word weight for terms and location weight for sentences are effective in improving the performance of summarization.

The purpose of this study is to analyze the writing activity materials presented in the thirteen middle school textbooks and determine if the writing activity materials are appropriate for the goals and contents of the 7th national curriculum. The writing activity materials are analyzed based on three criteria. First, the writing activity materials are analyzed based on Rivers'(1981) five writing guidances, which are specified with detailed writing activity materials. The first criterion was suggested by Young-Ran Lee(2004). Second, the writing activity materials in the textbooks are analyzed according to the criterion prescribed by the 7th national curriculum, which are specified with writing activities presented by Rivers(1981), Raimes(1983), Hedge(1988), and Beverly and Carol(1988). Third, the writing activity materials related to other skills, such as listening, speaking, and reading, in the textbooks are selected and analyzed according to the proportion of the integration of skills. The results are as follows: First, writing activity materials in the textbooks belong to the type of 'reproduction', ie. the second stage of Rivers' writing guidance, 'recombination, which is the third stage of Rivers' writing guidance, and the type of 'guided writing', noted on the fourth stage of the guidance. Second, the writing activity materials satisfy the criterion in the 7th national curriculum, as for the proportions, but they are not balanced. Third, most of the writing activity materials contain writing activities that involve non-writing skills such as listening, speaking and reading, but they are not balanced. Particularly, writing activity materials related to reading activities are common.

Bioactive peptides (BAP) showed excellent cosmetic activity than bio-materials such as caffeic acid (CA), gallic acid (GA), and nicotinic acid (NA). Caffeoyl tripeptide-1 (CT-1) is a BAP that is stabilized with Gly-His-Lys (GHK) tripeptide and CA by using Fmoc solid phase peptide synthesis. Digalloyl tetrapeptide-19 (DT-19) is stabilized by combining Lys-Glu-Cys-Gly with GA and nicotinoyl tripeptide-1 (NT-1) is synthesized by GHK and NA. According to experiments, CT-1 has an excellent anti-oxidant function even with a very small amount of 10 ppm CT-1. DT-19's tyrosinase inhibition activity has the better effect of about 28.57% in 0.01% and 33.33% in 0.005% of concentration and about 7.89% in 0.001% concentration than vitamin-C. In addition, NT-1 is safer than the NA. Almost BAPs like pal-KTTKS, acetyl hexapeptide, and copper tripeptide-1 have the anti-wrinkle effect while DT-19 and NT-1 are applicable for potential BAPs focused on the whitening effect. The three kinds of BAPs like CT-1, DT-19, and NT-1 consisting of amino acids are safe to the skin, and have more excellent stability than bio-materials which are found to be unstable and cause skin irritation. Due to the high biological activity of BAP in the field of skin care, its utilization will increase constantly.

Service industries nowadays have become the subject of a scientific research. However, unlike research on manufacturing, there has not yet been a broader presentation of important aspects theoretically and methodologically. The importance of service sector in both national and global economies has grown significantly. An active participation of service industries in the internationalization process, notably by licensing and FDI, has occurred over time. But a few sub-sectors still dominate on this process, for example, financial institutions such as banks, securities, and insurance as well as producer services in advertising and accounting. On the other hand, personal services that are owned by small- and medium- sized firm have limited capabilities in their transnational transfer. This paper attempts to examine various factors influencing decisions for these small- and medium- sized Korean beauty firms in entering to the foreign markets. Determining factors for these firms in the engagement of internationalization depends largely on competitive advantages in both domestic and host countries, and they may be different from those in the sub-sectors mentioned above. Based on previous researches, i identified three categories of independent variables(characteristics of firms, managers, and competition) that can influence decisions to enter to the foreign markets. Seven hypotheses have been tested by using a sample of beauty firms in Daegu city and Kyungbuk province. The results show that the intention of these firms to enter to the foreign markets is significantly influenced by the factors of the innovative character of CEO's, the competitiveness of firms, and size of firms.
