Purpose: In this study, we introduced a newly developed technique of operation for hallux valgus. We used a single dorsal incision to correct major components of Bunion in stead of two or three incisions, which had been used by most of surgeons for long time. Materials and Methods: Between 2003 and 2005, 27 feet with hallux valgus deformity were operated through single dorsal incision. 10 out of 17 patients underwent operation on both feet, 5 patient underwent operation on left feet, remaining 2 underwent operation on right. There were 16 women and 1 man. Average age of patients was 45 (range, 21-59). Post operatively all feet were evaluated by physical examination, Maryland Foot score profile, radiographic measurements and complication. Results: Maryland foot score profile increased from preoperative 67/100 to postoperative 95/100. Most patients satisfied pain relieve and cosmesis. Average preoperative intermetatarsal angle was 15 degrees, which were decreased to 9 degrees after operation and average preoperative hallux valgus angle was 32 degrees, which were decreased to 12 degrees after operation. Conclusion: According to our experience, the single dorsal incision technic for correction of moderate to severe hallux valgus deformities was rather safe and easily performed without noticeable complication with almost same results as multiple incisions technics. We highly recommend this technic to be tried by foot surgeons without hesitation.

In Communications are intended elicit respondses through a conversation or communication styles between speaker and audience. VTSO and the ship operator's intent to communicate well with each other thus leading to the conclusion that must be accomplished It should be completed with MRC which is a poor means to understand and persuasive manner, and conclusions expressed are easily able to derive strategic communication skills. Forever, but these expression and technic can not force where the operator deciding factor in the law frame should not spiral out of the border. VTSO communication skills should be taken into such factors would be high level technic. Now here's I'd like to study that occured in the maritime communications field to be studied deeper issues and a category of expression technic, expression for the VTSO.

The development of applications for vehicular ad hoc networks (VANETs) has very specific and clear goals such as providing intellectual safe transport systems. An emergency warning technic for public safety is one of the applications which requires an intelligent broadcast mechanism to transmit warning messages quickly and efficiently against the time restriction. The broadcast storm problem causing several packet collisions and extra delay has to be considered to design a broadcast protocol for VANETs, when multiple nodes attempt transmission simultaneously at the access control layer. In this paper, we propose an early intelligent alert broadcasting (EI-CAST) algorithm to resolve effectively the broadcast storm problem and meet time-critical requirement. The proposed algorithm uses not only the early alert technic on the basis of time to collision (TTC) but also the intelligent broadcasting technic on the basis of fuzzy logic, and the performance of the proposed algorithm was compared and evaluated through simulation with the existing broadcasting algorithms. It was demonstrated that the proposed algorithm shows a vehicle can receive the alert message before a collision and have no packet collision when the distance of alert region is less than 4 km.

This study is an primary analysis on convergence of porcelain lacquer painting art which is composed of porcelain art and raw lacquer technic. As a part of ceramic art, this study suggest 3 ways of porcelain lacquer decoration with understanding of its history and contemporary status. Lacquer technic gives stability for surface paintings and it also has various media to express its beauty. Porcelain lacquer decoration art contains artistic value and pragmatic purpose for daily life usage. These days, due to unavailability for mass production, it tends to be tried for art work purposes. However this artistic technic and value can be applied to porcelain goods, so that it will raise aesthetic pleasure and cultural diversity.

Purpose : It is important to reduce radiation dose associated with computed tomography (CT) scanning to as low as reasonably achievable (ALARA). With Dose Modulation Technic, user select a desired image quality and the system adapts tube current to obtain the desired image quality with greater radiation dose efficiency. In this paper, we presents a comprehensive description of fundamentals, clinical applications and radiation dose benefits of Dose Modulation Technic depending on Body Mass Index(BMI). Materials and Methods : In this study, 149 patients were examined(The mean age : $58{\pm}12.4$ years old). Biograph True Point 40 (Siemens, USA) and Gemini TF 64 (Philips. Cleveland) were used for equipment. When we used Care Dose 4D (Siemens, USA) and D-dom (Philips, Cleveland), we measured dose reduction and Computed Tomography Dose Index (CTDI) depending on BMI. Then we analyze data using SPSS Ver.18. Results : When we used Care Dose 4D, p-value is considered statistically significant by groups with the result that we compared Care Dose 4D with D-dom. On the other hand, p-value isn't considered statistically significant by groups using D-dom. Conclusion : Dose modulation based on the projection angle didn't affect degree of obesity. And When using Care Dose 4D, dose reduction rate in the normal patients were higher than the obese. In this study, there are errors on somato type. So I think more research have to be done. Then application of Dose Modulation technic can help in maintaining acceptable image quality while reducing radiation dose by 20-60% in most instances.

The purpose of this study is to investigate the effects of learning methods on students' information retrieval and information synthesis capability in web. This is an experimental study comparing the two different learning methods as task-based learning and technic-based learning. The findings of this study were as follows: 1. The task-based learning was more effective than the technic-based learning in information achievements as information retrieval capability (t= 3.59, p〈.05). 2. In the 1st retrieval (recall ratio t=1.81 precision ratio t=.61) of Naver Korean Web Retrieval, there was no significant difference (p〉.05). In the 2nd retrieval (recall ratio t=2.93 precision ratio t=2.45) and 3rd retrieval (recall ratio t=3.48 precision ratio t= 2.50), the task-based group was more effective than the technic-based group (p〈.05). 3. There was no significant difference in students' information synthesis capability between the task-based learning and technic-based learning (t= 1.95, p〉.05). The findings of this study suggest that the task-based learning approach is more effective to improve students' information literacy, and that professionals should consider better instructional principles for the improvement of instructional quality.

It is well known that the tracking a certain person is a vary needed technic in the humanoid robot. In robot technic, we should consider three aspects that is cloth color matching, face recognition and motion analysis. Because a robot technic use some sensors, it is many different with the robot technic to track a certain person through the CCTV images. A system speed should be fast in CCTV images, hence we must have small calculation numbers. We need the statistical variable for color matching and we adapt the eigen-face for face recognition to speed up the system. In this situation, motion analysis have to added for the propose of the efficient detecting system. But, in many motion analysis systems, the speed and the recognition rate is low because the system operates on the all image area. In this paper, we use the moving energy only on the face area which is searched when the face recognition is processed, since the moving energy has low calculation numbers. When the proposed algorithm has been compared with Girondel, V. et al's method for experiment, we obtained same recognition rate as Girondel, V., the speed of the proposed algorithm was the more faster. When the LDA has been used, the speed was same and the recognition rate was better than Girondel, V.'s method, consequently the proposed algorithm is more efficient for tracking a certain person.
