  • Purpose: The Purpose of this study is to develop a model for predicting agent churn group in the cosmetics industry. We develope two models, pattern model and matrix model, which are compared regarding the prediction accuracy of churn agents. Finally, we try to conclude if there is statistically significant difference between two models by empirical study. Methods: We develop two models using the part of RFM(Recency, Frequency, Monetary) method which is one of customer segmentation method in traditional CRM study. In order to ensure which model can predict churn agents more precisely between two models, we used CRM data of cosmetics company A in China. Results: Pattern model and matrix model have been developed. we find out that there is statistically significant differences between two models regarding the prediction accuracy. Conclusion: Pattern model and matrix model predict churn agents. Although pattern model employed the trend of monetary mount for six months, matrix model that used the amount of sales per month and the duration of the employment is better than pattern model in prediction accuracy.

  • This study was initiated to search for the most effective method for extraction of anthocyanins from Morus alba Fruits using organic acids and to evaluate the stability of the pigments at various storage environments. The anthocyanins were effectively extracted by addition of organic acids such as citric acid, malic acid and fumaric acid. The anthocyanins were not degraded at $25^{\circ}C$ and under a fluorescent light with 183 lux, but sharply degraded at $60^{\circ}C$.

  • Background and purpose: The purpose of this study is to review the recent achievements on ryodoraku and suggest new ryodoraku studies. Methods: The study papers related with ryodoraku, published in foreign countries and Korea up to the present, were collected first by internet search & journal. And then the collected papers were classified and summarized. Results and Conclusion: There are three study trends. One is finding some effect and analysis for some symptoms, another is finding a distinguishing mark and a diagnostic index, and the other is raising several points & providing solution & studying about relativity with another diagnosis. Some studies finding some effect and analysis for some symptoms are to be classified into four items(1. effect of drugs medication. 2. effect of ryodoraku therapy. 3. effect of other treatments. 4. effect of other treatments with ryodoraku therapy). Other studies finding a distinguishing mark and a diagnostic index are to be classified into two items(1. diagnostic index of symptoms. 2. distinguishing mark of disease). The other studies are to be classified into three items(1. ryodoraku introduction and raising several points at issue. 2. improvement machinery and tools. 3. studying about relativity with another diagnosis). Finally we need solving the ryodoraku problems(the condition of measurement and reproducibility, relation with Kyung-rak(經絡) and Ryodoraku, the reason of Ryodoraku points producing and etc.).

  • The aim of this study was to evaluate the clinical, radiographic and histopathologic features of 23 cases of solitary bone cyst by means of the analysis of radiographs and biopsy specimens in 23 persons visited the Department of Oral and Maxillofacial Radiology, School of Dentistry, Kyung Hee University and Chunbuk National University. The obtained results were as follows; 1. The incidence of solitary bone cyst was almost equal in males(52.2%) and in females(47.8%) and the prevalent age of the solitary bone cyst were the second decade(47.8%) and the third decade (21.7%). 2. In the signs and symptoms of solitary bone cyst, pain or tenderness revealed in 17.4%, swelling revealed in 13.0%, pain and swelling revealed in 21.7%, paresthesia revealed in 4.4% and 43.5% were asymptom and the tooth vitality involved in the solitary bone cyst, 76.5% were positive and 23.5% were either positive or negative. 3. In the location of the solitary bone cyst, 47.8% present posterior region, 21.7% present anterior region, 21.6% present anterior and posterior region, 4.4% present condylar process area. 4. In the hyperostotic border of the solitary bone cyst, 47.8% were seen entirely, 21.8% were seen partialy, and 30.4% were not seen. 5. In the change of tooth, 59.1% were intact, 18.2% were loss of the alveolar lamina dura, 13.6% were root resorption 4.55% were tooth displacement, 4.55% were root resorption and tooth displacement. 6. In the change of cortical bone of the solitary bone cyst, 39.1% were intact and 60.9% were thinning and expansion of cortical bone. 7. In the histopathologic findings of 9 cases, 33.3% were thin connective tissue wall, 11.1% were thickened myxofibromatous wall, 55.6% were thickened myxofibromatous wall with dysplastic bone formation.

  • Recent fashion business, is to promote and make a business strategy to realize a high added value to the first goal. Completion of the best men's clothing is only by making the pattern through a person's body size, making it as the best dressed. In this paper, we propose a system to automate production processes a significant impact on menswear production process, time and cost reduction in order to satisfy the needs of manufacturers and customers. Consequently, it is possible to provide optimal men's clothing by saving a time and expense of customers by, increases the customer's needs and men's clothing demand, it is possible to more easily perform to franchising custom men's clothing manufacturer.

  • In almost all of the Hand-made suit plants, while garment cutters are hard to measure the body size by their own, they are not quick. And each of the individual's standard is vague, so it is hard to get a consistency. So it will give the customers some displeasure with the body contact. To improve this kind of problems, in this paper proposes a efficient way that is hard to measure by the general image processing technology to measure when you manufacture a Hand-made suit and measure a body size by wearing a elastic band that has a printed mark that has some information of length and taking a picture of the body by a digital camera.

  • The oral administration of extracts of young radishes cultivated with sulfur after intravenous tumor cell injection achieved a marked reduction of pulmonary colonization in mice. Treatment of the mice with extracts of young radish cultivated with sulfur did not show any increase in the number of CD8+ or NK T cells in the spleen, indicating no influence on host immunity. Sulforaphane, which could be a candidate for an active compound from young radishes cultivated with sulfur, inhibited cell growth of B16-F10 melanoma cells. In addition, extracts of the young radish cultivated with sulfur-fed group showed enhanced quinine reductase (QR) activities in the liver and lung and a slight increase of glutathione S-transferase (GST) activity in the liver. These results suggested that the administration of extracts of young radishes cultivated with sulfur suppressed pulmonary tumorigenesis, possibly due to increased activity of detoxification enzymes in the liver and lung, and partly due to cell cytotoxicity.

  • Objective : Extracranial-intracranial(EC-IC) microvascular anastomosis was performed in 18 patients with hemodynamic cerebral ischemia and traumatic cerebral aneurysm, the aim of this retrospective study was to assess its value in neurosurgical field. Method : Of 18 cases, 17 case were hemodynamic cerebral ischemia and one was traumatic cerebral aneurysm. There were 14 superficial temporal artery(STA)-to-middle cerebral artery(MCA) anastomosis, 3 saphenous vein graft bypass(2 external carotid artery(ECA)-to-MCA, 1main trunk of the STA-to-MCA) and 1 radial artery bypass(ECA-to-MCA). Results : Bypass patency was confirmed by postoperative angiography in all cases except for two cases, postoperative cerebral blood flow of ischemic brain showed significant increased in all cases with good patency through bypass. Conclusion : Revascularization by EC-IC microvascular anastomosis to the ischemic brain eliminated ischemia and was associated with excellent good outcome and good patency rates.
