The purpose of this study is to grasp the chracteristics and the meaning of Korean poets' works which were written in Japanese in Japan in the 1920's. Most of these poets were studying abroad in Japan at that time, and announced a great number of poems in Japanese literary circles. Jung, Ji-yong was one of them, announced lots of poems on <Modern Landscape>(근대풍경). He was an imagist poet who accepted the European modernism by means of the understanding of Japanease literature and English literature. His poems could be divided by two parts on the basis of the relations of his Korean poems. The first part was poems written by JApanese again based on his former Korean poems, and so could not have fully it's originality. But the second part was poems which we could not find the same sort of poems in the list of his Korean poetry. So it could have an orginality by itself as such. These poems did not express directly a thought or an emotion, but figurated sensitively it by means of the image of objective things. Because he accepted the imagism, and intended to write a modern poetry by new writting skills according to the influences of Japanese imagist poets, such as Kitahara Hakyusu(화원백추). As the result, these poems could extend his poetic world, and made a catalytic action in the development of his Korean poetry. But his poems did not show the historical reality of those days. It leaves something to be desired in this point. Kim, Hee-mung, who was involved in the NAPF in Japan, was a poet that we could say he had been being on the opposite side of Jung, Ji-yong. Although we could not know well his personal history, most of his poems were works inspiring the struggle consciousness of the proletariat. Especially <the sadness of a foreign country>(이방애수) of them was a narrative poem telling a tragic story that a Korean labore had experienced the bitterness of national discrimination in Japan. With this work, one of Kim, Byung-ho's poems, <I am a Korean> expressed the sorrowful life of Korean wandering people and immigrants in Japan under the rule of Japanese imperialism. I could ascertain the national identity of Korean poets' poems in Japanese by these poems.

SAW-based capacitance sensors were developed by measuring the changes in the voltage ratio between an output inter-digital transducer (IDT) and an input IDT, induced by the variation in the capacitance between hemi-spherical conductive tips with diameters on the order of micrometers. We derived the transfer and sensitivity functions, which describes the ratio of the variation in the output voltage to the variation in the input voltage with a 2-port network model of a SAW based on Mason’s equivalent electro-acoustic circuit and analytical model for the apex capacitance. We then conducted an experiment to verify and measure the transfer function and the 3-D shape. The system was found to have an average resolution of approximately 10 nanometers. We also used the constructed system to measure nano- and submicro-sized 3-D shapes, and verified that the measurement results were accurate.
Confinement effects of Ni nanoparticles in ordered mesoporous materials for dry reforming of methane
박경수,조재민,함형원,배종욱 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0
For a dry reforming of methane (DRM), Ni-based catalysts have a lot of problems due to their thermal instability by a sintering of supported Ni nanoparticles (NPs) to form less active larger agglomerates at a high temperature as well as significant coke formation compared to the novel metal-based catalysts. In order to suppress those limitations for a commercial application, the ordered mesoporous materials of SiO<sub>2</sub> and Al<sub>2</sub>O<sub>3</sub> were used to solve the deactivation of Ni nanoparticles, which were synthesized by a chemical reduction method by using nickel (II) acetylacetonate with borane tertbutylamine. The Ni nanoparticles were successfully confined in the ordered mesoporous structures, which suppressed the aggregations of the confined Ni nanoparticles thus showed a stable production of syngas at a high temperature without any significant aggregation and coke deposition.

This paper aims to find out and settle Lee, Ju Hong's poems with investigating journals and newspapers in the colonial period, and prove characteristics of the world of his poems. the results so far achieved is as follows. 1. As the results I investigated Lee, Ju Hong's poems, I could find out newly three pieces which was published each in 『Jungoe Ilbo』, 『Urideul』(i. e. We), and 『Dong Yang Ji Kwang』, and make sure bibliographical facts of four works exactly. 2. I could divide his poems into three categories according to characteristics of the poetic world. First category consists of woks that express the homesickness and the feeling of loneliness before the early in 1930. Second category is composed of the proletarian poems that expose the proletarian consciousness criticizing the world of class contradiction and the tragic affairs of life based on socialism from 1930 to 1935. And works of third category are poems that express the mental state of an autism or a self-torment, or the image of petty bourgeois from 1936 to 1945.(Pusan University of Foreign Studies)
