  • The local appearance-based method is one of the face recognition methods that divides face image into small areas and extracts features from each area of face image using statistical analysis. It collects classification results of each area and decides identity of a face image using a voting scheme by integrating classification results of each area of a face image. The conventional local appearance-based method divides face images into small pieces and uses all the pieces in recognition process. In this paper, we propose a local appearance-based method that makes use of only the relatively important facial components. The proposed method detects the facial components such as eyes, nose and mouth that differs much from person to person. In doing so, the proposed method detects exact locations of facial components using support vector machines (SVM). Based on the detected facial components, a number of small images that contain the facial parts are constructed. Then it extracts features from each facial component image using principal components analysis (PCA). We compared the performance of the proposed method to those of the conventional methods. The results show that the proposed method outperforms the conventional local appearance-based method while preserving the advantages of the conventional local appearance-based method.

  • Background Reconstruction of combined orbital floor and medial wall fractures with a comminuted inferomedial strut (IMS) is challenging and requires careful practice. We present our surgical strategy and postoperative outcomes. Methods We divided 74 patients who underwent the reconstruction of the orbital floor and medial wall concomitantly into a comminuted IMS group (41 patients) and non-comminuted IMS group (33 patients). In the comminuted IMS group, we first reconstructed the floor stably and then the medial wall by using separate implant pieces. In the non-comminuted IMS group, we reconstructed the floor and the medial wall with a single large implant. Results In the follow-up of 6 to 65 months, most patients with diplopia improved in the first-week except one, who eventually improved at 1 year. All patients with an EOM limitation improved during the first month of follow-up. Enophthalmos (displacement, 2 mm) was observed in two patients. The orbit volume measured on the CT scans was statistically significantly restored in both groups. No complications related to the surgery were observed. Conclusions We recommend the reconstruction of orbit walls in the comminuted IMS group by using the following surgical strategy: usage of multiple pieces of rigid implants instead of one large implant, sequential repair first of the floor and then of the medial wall, and a focus on the reconstruction of key areas. Our strategy of step-by-step reconstruction has the benefits of easy repair, less surgical trauma, and minimal stress to the surgeon.

  • The purpose of the study is to get some pieces of prior information to eventually develop competitive swimming suit designs with Korean traditional images. The study has been accomplished in following steps. First, as theoretical research, the history of swimming suit design and the requirements in designing competitive swimming suits were studied. Second, as practical research, at first, the trend of the competitive swimming suit designs in the national swimming suit market was examined. And then. the questionnaire surveys of both professional and amateur swimmers about their design preferences with purchasing and fabric-related tendencies were conducted for understanding professionals' characters more exactly. This data were analyzed through cross-analysis and multi-response analysis and x 2 was used. The results of this study can be summarized as follows : First, athletes' preferential design tendency for the swimming suit designs were examined in the aspects of style, color, pattern, logo, and accessary. In style, female athletes preferred an athletic one-piece style and male ones preferred a brief style. In color. neutral, mostly black was preferred most and cold color group like dark blue and navy blue next, regardless of sex. In addition, they preferred similar color coordination. In pattern, though solid fabrics were mostly preferred in both sexes, especially Taeguk motive were considered the most appropriate pattern to show Korean image. Besides, logo was considered importantly, and swimming caps and goggles of accessaries were generally used. Second, athletes' swimming suit purchasing tendency was as a following. the number of swimming suits possessed was more than 4 pieces. the durable period was less than 3 months. and the most important point considered in purchasing was an easy fitting for men and a design with an easy fitting for women. And most of swimming athletes preferred foreign products than domestic ones, which was attributed to excellent quality, easy fitting, and good design. and so on. Third, in fabric-related tendency, food touch, easy fitting. and opaqueness were considered importantly. and durability to chlorine, elasticity, color fastness, easy draining, lightness, and so on were demanded forward.

  • Objectives : In order to ensure safe acupuncture treatment, the quality of the needle tip is essential. But, there have not been so many studies about the quality of the acupuncture needle tip. For this reason we have been already reported about the quality of acupuncture needle tip in Korea using scanning electron microscope(SEM) in 2002, 2003. In order to compare than other society, we investigated the current condition of the tips of the acupuncture needles sold in Europe. Methods : We obtained the needles made by 7 companies, which are sold currently in Europe, and selected 50 pieces out of 100 pieces from each company by randomized methods. And then we observed the tip of each needle using a scanning electron microscope at ${\times}800$ magnification. Results and Discussion : We found that needles had several defects such as scratch marks on the surface, metallic scuff, lumps and irregularities of the needle tips, stubbed or malformed tips, tips of point off-center, peeled off coated tips, same as Korean needles. There was much difference on the quality of needles among the manufacturers, and some needles seem to need thorough quality control. Allowing for the high price, the quality of some needle in Europe generally are better than that of Korean needles. But some Korean needles hold a top position than European ones in quality. We want a good industrial standard to be made in acupuncture manufacturing fields in the near future, because the safety is not less valuable than the efficacy in medicine.

  • In this study on the Persiandress called Persiandress or Mediandress, its names, styles, and structures that are still subject to a great deal of controversy were investigated. In addition, the reason why the Persiandress was wrongly named as Kandys by the early researchers was also examined. The documents of reliefs on the Apadanastairs in Persepolis and the European papers concerning this themes were subject of this analysis. Such investigation and examination results are summarized as follows. There is still no agreed name describing the Persiandress, which is called "Persiandress" or "Mediandress". Further, there is no definite conclusion on whether the Persiandress was made in one piece or two pieces. The first person who insisted that the Persiandress was made in one piece is a German archaeologist, Ernst Herzfeld. He said that the Persiandress was made in one long tetragonal piece, had a hole in the middle for head, and had lots of pleats when it was tied with a belt. On the contrary, researchers who insisted that the Persiandress was made in two pieces stressed the sleeve pleats in four folds, which is one of the representative characteristics, and said that such four-fold sleeve pleats would not be formed when the Persiandress was made in one piece and worn by a belt. Consequently, they have conducted studies according to their insistence and the resultant pattern. Kandys, the Median's typical dress, is a coat worn over the jacket and trousers. Although it had sleeves, the Median did not use them. Indeed, Kandys was used as a kind of cloak. However, the wrong term, Kandys is still used in Korea. So, it is necessary to correct use of such wrong term.

  • The purpose of this study was to investigate changes in the cooking process of red beans used to prepare Bab (cooked rice) in cooking books published from late 19th century to the present. There are 3 different types of Bab that use red beans; Jungdeungbab, Patbab and Patsura, and cooking process vary between different cooking books. For making Jungdeungbab, one method is to cook the red beans in the water first, and then only the water, after draining the cooked red beans, is used to cook rice. The other method is to smash the cooked red beans and collect the water that passes through the smashed red beans to cook the rice. For Patbab, 2 cooking methods were found. One is to cook the whole red beans first and then to add them to the rice for cooking. Another method is to break the red beans into two pieces and mix them with rice and cook them together. Patsura is the red bean used to prepare the Bab offered to Kings during the Chosun dynasty(1392~1910). The cooking process of Patsura is similar to both Jundeungbab and Patbab. In Ijogungjeongyoritonggo(1957), the cooking method of Patsura is similar to that of Patbab; breaking red beans into two pieces and then mixing them with rice and cooking them together. Another method, which is similar to Jungdeungbab, is found in Ijogungjeongyoritonggo(1957) and Hangukyoribaekguasajeon(1976). In Ijogungjeongyoritonggo(1957), the cooking method is to cook the red beans first and then squeeze them after putting them into a sack and then using the extract to cook rice. In Hangukyoribaekguasajeon(1976), the red bean is prepared by first cooking red beans in water, and then only the water, after draining the cooked red bean, is used to cook rice. In further studies, the cooking procedures used in the previous period of the late 19th century should be examined.
