When traditional flap techniques are not feasible, we apply flap prefabrication, which is more complicated and sophisticated but supplies large and thin flaps. There are some disadvantages to the technique that require improvement, such as venous congestion after flap transfer, which requires months for neoangiogenesis and necessitates a vascular carrier. Here, the author presents a new technique, called as 'microdissected prefabricated flap,' to successfully produce a safe, large, and thin flap. This technique is based on the microdissection of the perforators to the greatest extent possible, spreading them out into the subdermal level and using them as a carrier. The details and the application of this technique are presented and reported.

This study attempts to detect a shot boundary in films(or dramas) based on the length of a sequence. As films or dramas use scene change effects a lot, the issues regarding the effects are more diverse than those used in surveillance cameras, sports videos, medical care and security. Visual techniques used in films are focused on the human sense of aesthetic therefore, it is difficult to solve the errors in shot boundary detection with the method employed in surveillance cameras. In order to define the errors arisen from the scene change effects between the images and resolve those issues, the mixed algorithm based upon color histogram, edge histogram, and optical flow was implemented. The shot boundary data from this study will be used when analysing the configuration of meaningful shots in sequences in the future.

Stone is one of the oldest and most popular materials used on the external wall because of its durability, abundance and aesthetic effect. However, there are two main problems in the existing pin hole construction method. One is uniformity of construction quality, and the other is a repair work of stone panels. Therefore, a new method is needed to overcome these problems. This paper presents a new stone curtain wall system using under cut anchor and secondary holes that was developed by authors. The improved quality and reduction of construction period can be obtained by this system.

Most of printing paper market today have been occupied by western paper and some machine-made Hanji used don't show the characteristic advantages for traditional hand-made Hanji. Although hand-made Hanji has an aesthetic and qualitative value, it has limited uses because of poor printability as printing paper. Unlike western paper, conventional Hanji cannot be used as Printing paper because it is impossible to make the clear formation of printed dot and to develop a high level of sizing and picking problem occurs during printing. Improvements of physical and optical properties such as roughness, smoothness, air permeability, contact angle, opacity, and paper gloss as well as sizing level were accomplished through internal and surface sizing and calendering, which made the paper better suited for printing and decreased problems during printing.

There is an increased interest in having beauty regardless of ages and sex with improvement of the national income level and increase in social activities. Competition within the beauty service industry is increasing rapidly because of global impact within Korea wave. Thus, active public relations and offering distinguished service in the beauty service industry are important. Also, uniforms play an important role in providing an image differentiated from other brands and presents professionalism to the customer. Therefore, we determined function and design of uniforms required in beauty service industry by researching wearing realities, satisfaction, preferred designs and functions of uniforms from hair shop staff. Functional and aesthetic uniforms play an important role to enhance the staffs' sense of belonging. In addition, it is good for the image of hair shop. Special design mirroring job characteristics with expression of differentiated personalities is needed. However, the research was conducted only in the hair shop in Seoul, Daejeon, and Gyeonggi-do. Further studies on much wider areas will be needed.

The purpose of this study was to identify factors related to residential satisfaction, and to examine the rural housing and village environment which enable to derive what should be considered in the future rural housing improvement. Data were collected by questionnaire survey in 11 rural villages - suburban rural area, plain rural area, intermediate rural area, mountainous rural area. The major findings are as follows: 1) The rural residents rather dissatisfied with'management/maintenance','economic value','facade'in housing level, The overall housing satisfaction level was just medium(neither satisfied nordissatisfied). 2) They also dissatisfied with'playground for children','education condition','medical facilities', 'market'in village level. The overa'll village satisfaction level was just above average(slightly satisfied). 3) Vrom the result of ANOVA test, there are no significant differences in residents evaluation for tiousing and village attributes among 4 rural areas. 4) Factor analysis identified six rural housing environmental factors:'inside utilities','housing size' 'aesthetic aspects','safety','privacy','outside utilities'. 5) For the rural village environments six important factors were derived :'public services','commercial convenience facilities','social interaction','environmental pollution','amenity','agricultural service facilities'.

In recent domestic automotive industry, applications of computer simulation to the manufacturing of stamping dies for inner and outer body panels which greatly affect durability and aesthetic quality of automobiles, have been increased. Enhancement of die quality, and reduction of total die manufacturing time and consequently manufacturing cost are the visible outcome. However, to successfully apply the result of simulation by a commercial package to the die manufacturing, development of an optimal die manufacturing process is required upon the completion of analysis of forte and shortcomings of available sheet metal forming softwares in the market. Based on the results of numerical analysis of front door outer panel forming, this paper evaluates the applicability of simulation results to the real die making for automotive body panels. Also, it attempts to select an optimal die manufacturing process including design, machining and tryout. Lastly, it discusses the expected effects by adopting the selected process in a real stamping die manufacturing facility.

Increasing the vertical dimesion affects not only functional problems but also the facial appearance. In particular, when restoring the reduced vertical dimension, it is important to evaluate facial appearance because the change affects the patient's aesthetics. Cephalometric radiographs can predict changes in the facial appearance through skeletal and vertical classifications using anatomical indicators, and the changes before and after treatment can be easily observed, which could serve as good data in evaluating treatment success. In this study, comparative evaluation was performed through cephalometric radiography, and the aesthetic and functional improvement was confirmed.

Posttraumatic facial deformities (PTFDs) are very difficult to correct, and if they do occur, their impact can be devastating. It may sometimes be impossible for patients to return to normal life. The aim of surgical treatment is to restore the deformed bone structure and soft tissue to create symmetry between the affected side and the opposite side. In the process of managing PTFD, correcting enophthalmos is one of the most challenging aspects for surgeons because of difficulties in overcoming the scar tissue and danger of injuring to the optic nerve. In this article, surgical options for reconstruction of the medial wall, floor, lateral wall, and roof of the orbit are described. To optimize aesthetic improvement, additional cosmetic procedures such as facial contouring surgery, blepharoplasty and rhinoplasty can be used. Plastic surgeons should join emergency trauma teams to implement an overall treatment plan containing rational strategies to avoid or minimize PTFD.

부분 무치악 환자의 구강회복을 위해서는 임플란트를 이용한 치료 방법이 널리 활용되고 있다. 임플란트를 이용한 치료방법은 크게 고정성 임플란트 보철물과 가철성 임플란트 보철물로 나뉠 수 있으며, 골 흡수가 심한 환자의 경우 심미적이고 경제적인 이점을 갖는 가철성 임플란트 보철물이 치료 옵션으로 활용될 수 있다. 특히 소수의 임플란트에 Milled-bar와 부가적인 유지장치를 이용한 보철물 제작 시, 임플란트 고정체 간의 연결고정 효과 및 의치의 유지력과 안정성이 증가할 수 있다. 또한 의치상을 통한 구순 지지를 통해 심미적인 보철물 제작이 가능하다. 본 증례의 환자는 상악골의 심한 골 흡수를 동반한 소수의 잔존치를 갖는 부분 무치악 환자로 전치부 및 소구치부위에 임플란트를 3개 식립 후 캐드캠을 이용하여 제작된 Milled-bar와 ADD-TOC 어태치먼트를 이용한 임플란트 부분 피개의치로 치료하였다. 그 결과 어태치먼트를 이용한 clasp 제거 및 의치상을 이용한 구순 지지를 통해 심미성을 높였으며, Milled-bar를 통한 교합력 지지와 의치 안정성을 확보하였다. 또한 환자의 이물감 해소를 위해 구개부 피개량을 줄인 금속 구조물의 피개의치를 제작하였으며, 만족스러운 결과를 얻었기에 보고하는 바이다.
