Free flap having been used for reconstruction of skin and soft tissue defect in various areas in a body is spreading up its application for not only functional reconstruction but also aesthetic reconstruction. Authors met with good results minimizing the demerits of anastomosis using suture through microvascular anastomotic device, hereupon, we intend to report this. We worked with 27 cases that used microvascular anastomotic device for venous anastomoses among patients who were processed free flap in our hospital. Age ranged from 12 to 63 (average 43.2), and there were 12 females and 15 males. As a result of a follow-up by 3 months - 5years (average 11.3 months), there was no particular complication in the anastomosed vein except 1 cases among 27 cases that sutured their veins through microvascular anastomotic device. Use of microvascular anastomotic device at free flap shortened the time required for vascular anastomoses to reduce ischemic time of tissue, and minimized the damage of intima during anastomoses and made easy anastomoses possible even in case the difference of diameters of blood vessels being sutured is wide. As well, even for survival rate of flap, satisfactory results were obtained compared with using suture. Consequently, it is concluded that use of microvascular anastomotic device in free flap is a useful way that can substitute existing anastomosis using suture.

This article was examined that the behavior of which they select hair equipment and a product may be significantly influenced by an interest in appearance during adolescence. This study was presented that according to gender, a girl student has higher confidence in appearance than a boy student, and also the higher the confidence in the girl's appearance, and they use more hair products. Moreover, the boy students are higher in than a girl student in the rate of dependence on hair equipment, so the boy students intend to use hair equipment. Therefore, this study was presented that the gender and an interest in appearance is important variables which influence to hair fashion of adolescence on an equipment and a product during presenting a hair-style, an interest in appearance of adolescence significantly influences on explaining the degree of hair equipment and leverage products as well.

The purpose of burn-in is to eliminate the early failures of the products before they are delivered for customer use. Therefore burn-in should he continued until one is reasonally sure that all the weak items have failed, thus leaving the remaining items in a healthy state of reliability. From this point of view, burn-in time dependent costs such as a cost per product per burn-in time, and cost of repair of the product per failure occurred during burn-in time will he increased. Conversely, the cost of field repair of the product per failure occurred during the guarantee period will be decreased since the early failure of the product is fully eliminated during burn-in. Hence, this paper intend to determine optimal burn-in time which minimize the total of above costs associated with burn-in.

Cultural properties are valuable objects, which have exposed insevere environment and inherited for a long time but we don’t have correct information concerning materials, structure and skill of manufacture. Because the cultural properties have been destroyed by the deterioration elements as like wind, this must be carefully treated for investigation of exhibition and storage. Even if the observation is scientific research, we must not take actual sample from the object for obtaining information concerning the nature materials and skill of manufacture. so it is elementary principle to use non-destructive investigation method as analytical methods for cultural property. This contribution discusses the present condition and problem of X-ray fluorescence acting as a representative non-destructive investigation method and the difference of statistics to be connected with determination and finally explains the intend facts for analysis of data.

Large logistics centers are being built around the world. Most of these buildings have characteristics of long span and heavy load, and use PC (precast concrete) structure for quick construction. There have been few attempts to systematically analyze the various influencing factors of PC erection planning. In this study, we intend to analyze the influencing factors necessary for the creation of a sustainable PC erection planning algorithm.

Premise was needed to develop and utilize forestland for productive use. First, the market price of forestlands should be fixed on a reasonable level. Secondly, it should be ascertained whether efficient and economical use of capital is possible when individual investors intend to develop the forestland. Therefore, this study recommends the method for estimating the market price of forestland and theoretical methodology on feasibility of development promotion for individual investors.

Currently, convenience stores, which are naturally located within a 1-minute walk, are easily accessible, so customers can easily purchase the items they need, and now they are indispensable places for people. In line with modern society that focuses on buying and selling goods quickly and easily, such as 'convenience' and 'quickness', convenience stores also have been changing by marketing such as home-delivery service and storage of fresh products, not just simply selling goods. In addition, by utilizing application software, we can use everything with one smartphone that we use a lot, in order to provide reservation delivery, pickup, and subscription services. In this study, we conducted experiments focusing on the factors of convenience store service quality and users using convenience stores, and examined how these experiments affect behavioral intentions of customers through their emotional responses. As a result, it was confirmed that empathy had a positive (+) effect on the pleasure of customers, and reliability had a negative (-) effect on arousal. In addition, it was found that empathy had a positive (+) effect on arousal, and responsiveness and empathy had a positive (+) effect on dominance. Finally, it was found that pleasure and dominance had a positive (+) effect on the loyalty of customers. In this study, we intend to provide basic data on existing or future convenience stores.

This study extracts the several informations by computerizing the maps of the new city, i.e. Yang-San, MuI-Gum. This cities are being constructed by Land Coporation, and a map of province based on 1:50,000 scales were digitalized depending on topography by digitizer. Several information was taken, by computerizing a existing design maps, with digitalized maps used. Also, there is map number based on each scale, and measure a settlement of the foundation for constructing a facility in a study region, then intend to use information. This paper aims at using old data such as ancient writing books by computerization permanently.

In this dissertation, in the light of the above situations, we intend to use new approach for stable and fast backup system. The approach that we propose network and software infrastructure has three different ways by comparison with existing network backup systems. First of all, we use a socket communication so that resolve the shortcoming of weakness of securities; second, TBD utility for minimizing target system loads in the way of instant operating; and third, time division and bandwidth division backup method considered transfer data size(byte) might be useful more stable and fast comparing with FTP Transfer.

Level-Based Education is necessary for the multi-cultural learners because they tend to have the academic underachievement and learning deficiency that cause the huge educational gap. However, it is very hard to make the best of competence for the multi-cultural learners in the classroom. So, it is needed to suggest how we can use the educational contents that are appropriate for the Level-Based Learning and Individual Learning to make good use of teaching the learners from multi-cultural families. However, developing the new educational contents takes much time and cost, we have to improve existing contents for the student from multi-cultural families to use it. Hence, the purpose of this thesis is to develop the educational appropriateness evaluation scale to verify the educational contents that are for the multi-cultural students based on the educational content's evaluation tool, so by developing the scale, I intend to evaluate the 4~6 grades' Korean contents of the E-learning service and provide the ways of improvement.
