  • Electric current flow was observed through imogolite film when imogolite ($(HO)_3Al_2O_3SiOH$) was exposed to water molecules and connected to external electrodes. Current flow was due to the bound water on the surface of imogolite. Current flow increased as the pH of the water decreased. The current-voltage (I-V) measurements from a field effective transistor (FET) using $H_2O$/imogolite film revealed that the current carrier in $H_2O$/ imogolite had p-type characteristics, i.e. the carrier was probably $H^+$. The possible mechanism for current transportation in imogolite/water was also suggested in this paper.

  • In this research, the changes of spaces on Namsan-Park and of the meaning of the park from the late 1900s through the early 1908s are analyzed, and the results are provided as follows. To begin with, inserting a concept of park to Namsan provided people with limitation in understanding definition of park, which indicated finite and constrained space, so that it distracted people from using spaces on Namsan. At that time, since the park was considered as one of key factors to establish Modern city, it was distinguished to the urban structure which had existed. After then, Joseon shrine, settled in Hanyang-Park, absorbed in functions of the park, so that the term of Hanyang-Park meant an area around the shrine or a boundary of the space. In addition, the particularity of Joseon shrine sometimes discouraged people from using the park spaces as well as spaces on the shrine, which led to decline the publicity of the park. However, Joseon shrine was correlated and planned with infrastructures of the city, Kyeongsung, not only physically but also visually in that Joseon shrine played role in one of components in Kyeongsung performed as an entertaining city such as a theme park. Lastly, Seoul is no longer subordinated and dependent city but has dramatically changed as a prominent city after regaining of independence in 1945. This indicates that the entertaining function of the old city was dismantled or reduced or transferred to public spaces, especially Namsan-Park. Consequently Namsan-Park has diverse and complex characteristics like traits of Kyeongsung, playing a pivotal role in providing cultural spaces, and its spatial organization is divided and planned based on various facilities and buildings on the park. This organization has a negative effect on the city and the park by decreasing in connectivity between them.

  • A new technique for low temperature crystallization of amorphous silicon, called field aided lateral crystallization(FALC) was attempted. To demonstrate the concept of FALC, thin layer of nickel(30${\AA}$) was deposited on top of amorphous silicon film and the electric field was applied during the crystallization. The effects of electric field on the crystallization behavior of amorphous silicon film were investigated.
