Today, digital technology is extending its influence to fashion design, which is closely related to people's lifestyle. In order for people to access information all the time, every place, people have to wear these devices all the time, every place. Intelligent wear allows people to communicate with their own body, other persons or surrounding real-time. The purposes of this study are to define 'Intelligent wear' by looking through the similar terms of intelligent wear on related fields, to analyze characteristics of intelligent wear and to provide not only theoretical data but also, practical data far product development on both functional and aesthetic sides. In this study, usefulness provided by intelligent wear were identified in the concept of instrumental & expressive function. For the aim of the study, literature and case study were considered at the same time. The conclusions are as the following. The characteristics of intelligent materials were found to be information, intelligence and protection, the characteristics of intelligent manufacture were combination and virtual reality. And The characteristics of intelligent products were multi-function, transformation, camouflage. Integration of operability function extends human ability and the area of human activity, entertainment, and communication, and provides convenience. Consequently, development of intelligent wear should promote through not only computer engineering but also, connection to other fields. Most of all, there is a need for active research in clothing design and the fashion design since intelligent wear is after all, clothing.

Hemifacial microsomia (HFM) patients may experience emotional withdrawal during their growth period due to their abnormal facial appearance. Distraction osteogenesis at an early age to improve their appearance can encourage these patients. Some abnormalities of the affected side can be overcome by distraction osteogenesis at an early age. However, differences in the growth rate between the affected and unaffected sides during the rest of the growth period are inevitable due to the characteristics of HFM. Therefore, re-evaluation should be performed after completion of growth in order to achieve stable occlusion through either orthognathic surgery or camouflage orthodontic treatment. An eight-year-old patient visited the clinic exhibiting features of HFM with slight mandibular involvement. He received phase I treatment with distraction osteogenesis and a functional appliance. Distraction osteogenesis was performed at the right ramus, which resulted in an open bite at the right posterior dentition. After distraction osteogenesis, a functional appliance and partial fixed appliance were used to achieve extrusion of the affected posterior dentition and settlement of the occlusion adjustment on the unaffected posterior dentition. The patient visited the clinic regularly for follow-up assessments, and at the age of 20 years, he showed facial asymmetry of the mandible, which had deviated to the right side. He received orthodontic treatment to improve the occlusion of his posterior dentition after the growth period. Without orthognathic surgery, stable occlusion and a satisfactory facial appearance were obtained through camouflage orthodontic treatment.

The purpose of this study is to analyze changes in military uniform design according to the type of war in history and to suggest factors to be considered when designing military uniforms. Military uniform in this study has been limited to uniforms of land active soldiers and not only includes battle dress but also bombproof helmets, combat boots and webbing systems. Western military uniform was investigated starting from World War I focusing on the United States, United Kingdom, Germany and the Soviet Union, and Korean military uniform was analyzed starting from the Korean Day of Independence. Historical research, case studies and in-depth interviews were included in the study. World War I was a trench war. Khaki colors began to be used in battle dress, and steel helmets and gas masks were invented. World War II was a full-stale war. Many kinds of uniform were designed with various environments and roles of soldiers in mind, and camouflage was adopted in military uniform. Modern wars were wars of technique. Strong protectors were invented and diverse camouflages were adopted as rifles became increasingly accurate and biochemical weapons started to be used. Korea referred largely to the uniforms of the United States because it lacked both information on war and the financial power to invest in development of military uniforms. Finally, this study presents 5 factors to be considered when designing military uniforms: protection, camouflage, mobile and utility convenience, compatibility and symbolism. Wars of the future are predicted to be information wars utilizing realtime information collected through computers. Therefore new military uniforms with computers, communication devices and strong protective capacities need to be developed. This study aims to provide a theoretical basis for designing military uniforms of the future.

The nose is shaped as a pyramid and is the most prominent portion of the face. Nasal bone fractures are thus more frequent than those of the maxilla and zygoma. Whether the nasal bone fractures are corrected or not due to unnecessity of surgical treatment, the incidence of posttraumatic deformity occurs frequently. In Asian patients, even the corrected noses look low-lying and flat. To resolve these problems, we corrected the posttraumatic deformity of the nose with a combined procedure of nasal ostectomy and augmentation rhinoplasty. From 2000 to 2004, this procedure was performed in fifteen patients with posttraumatic nasal deformity. There were four female and eleven male patients with an average age of 32 years(range 19 to 52 years). All patients had previous trauma history. Of these, closed reduction was performed on 13 patients and no treatment was 2 patients. The deformed noses were corrected through lower columellar incision, by ostectomy or osteomy, and augmentation with silicone implant. We gained satisfactory results of correcting the deformed noses, except one case with implant deviation. Our method for the correction of traumatic nasal deformity proves to be simple and safe. The camouflage effect with silicone implant overcomes an unsatisfactory correction and brings a excellent cosmetic results.

본 논문에서는 은밀하게 통신 신호를 전송하기 위해 돌고래 휘슬음을 모방한 통신 기법을 제안하였다. 기존의 CSS(Chirp Spread Spectrum) 변조 기법은 돌고래 휘슬음을 정해진 시간 단위에 따라 여러 슬롯으로 나누고 각 슬롯에 상향 및 하향 처프 신호를 통해 변조하는 기법이다. 이에 따라 본래의 돌고래 휘슬음과의 시간-주파수 특성 차이가 발생하게 되어 모방 성능이 저하된다. 본 논문에서는 이러한 왜곡을 제거하기 위해 지연 시간을 기반으로 하는 변조 기법을 제안하였다. 전산 모의실험 결과 기존의 CSS 변조 기법에 비해 제안 방법의 비트오류율 성능이 약 3.5 dB ~ 8 dB 우수하였으며 시간-주파수 영역에서의 상호 상관도를 통한 모방 성능 평가에서도 CSS 변조 기법에 비해 우수한 것을 보였다.
