Most of the studies on traditional houses dealt with the exiting houses which were constructed Chosun Dynasty. But It is to be classified into many items which were point of view period, regional group and social condition. The purpose of this study Is compare early-Chosun Dynasty with late-Chosun Dynasty that the Visual Structure of traditional houses in Yang-Dong village. Early-Chosun Dynasty and late-Chosun Dynasty of traditional houses were well preservation in Yang-Dong village. Therefore traditional houses in Chosun Dynasty are able to classified according to period type of Early-Chosun Dynasty and late-Chosun Dynasty, which a study on the compare spatial composition of traditional houses in Yang-Dong village.

The Chosun Exhibition was held in 1929 and the Architectural Association of Chosun(AAC) displayed model houses fur the fair. These model houses represented the new housing trend of the Chosun society, so this research was necessary to find out the facts. The main materials used for this research were issues from 'Chosun and Architecture'. The objects of this research was to find out the activity of the AAC and to classify the displayed model houses according to the structure, plan and interior. These three model houses depicted the improved housing designs at that time. Improved housing designs also depicted the convenience of everyday life, hygiene, improvement of facilities and the application of modem lift to that era. Therefore, these three houses would be revaluated as new models of houses for the Chosun society under education activity by the AAC.

Silicon nanowires were detached and obtained from silicon nanowire arrays on silicon substrate using a ultrasono-method. Silicon nanowire arrays on silicon substrate were prepared with an electroless metal assisted etching of p-type silicon. The etching solution was an aqueous HF solution containing silver nitrate. SEM observation shows that well-aligned nanowire arrays perpendicular to the surface of the silicon substrate were produced. After sonication of silicon nanowire array, an individual silicon nanowire was confirmed by FESEM. Optical characteristics of SiNWs were measured by FT-IR spectroscopy. The surface of SiNWs are terminated with hydrogen.

We describe the synthesis and characterization of silicon nanoparticles prepared by the solution reduction of silicon tetrachloride by lithium naphthalenide and subsequently with n-butyllithium at room temperature. These reactions produce silicon nanoparticles with surfaces that are covalently terminated with butyl group. Reaction with lithium aluminium hydride instead of n-butyllithium produces hydride-terminated silicon nanoparticles. The butyl or hydride terminated silicon nanoparticles can be suspended in hexane and their optical behavior have been characterized by photoluminescence spectroscopy. Stabilization of silicon nanoparticles were investigated upon illumination, indicating that as-prepared silicon nanoparticles are very stable at room temperature for several days.

대학교 캠퍼스를 방문하는 최초 방문자 대부분은 넓은 부지와 많은 건물들에 의해 혼란을 겪는 경우가 많다. 건물 명칭이 표기되어 있지만 목표건물의 위치를 쉽게 파악하기는 어렵다. 목표 건물의 위치를 파악 하였더라도 건물 내부에 대한 정보를 찾기는 더욱 힘들다. 4차 산업 혁명 시대의 급속한 발전으로 다양한 신기술이 등장하는 과정에서 증강현실(Augmented Reality) 기술이 대두되고 있다. 본 논문에서는 증강현실 기술을 이용하여 조선대학교의 건물 이름과 그 건물에 대한 정보를 제공하는 안내시스템 "See-Chosun" 어플리케이션을 제안하기로 한다.
