In the late Japanese colonial period, Jung Ji-young opened up the field of poetry criticism as a managing editor of poetry part in 「MunJang」. From this time, he emphasized Theory of Oriental Painting as well as the method of a Confucian classic. These styles were reflected into 「BakRokDam」, which is a masterpiece of landscape poetry. For example, in 「JangSuSan·1」, 「JangSuSan·2」, ``white light`` was coincided with the flow of Tao. ``Stone`` and ``water`` corresponded to strong will and the pedigree of national characteristic. Topic was also related to these styles. In addition, it was an example of the roundabout writing because it was against the Japanese colonial authority. To understand this poem, the subject concept of modern times get through while considering three dimensional space viewing of the Oriental paiting and verbal thinking of the East Asia. In this area of Landscape Poetry, Gi-centered theory was founded, since Jung Inbo, Kangwha school, might be effected on the works of Jung Jiyoung. Further detailed research will discuss about the relationships with Jung Inbo.

본 연구는 황금새(Ficedula narcissina)의 여러 아종 중 한국에 도래하는 아종의 형태학적 특징과 봄·가을 이동 양상을 파악하기 위해 2005년 4월부터 2008년 5월까지 전남 신안군 홍도와 대흑산도, 일본 이리오모테섬에서 각각 실시하였다. 형태학적 분류 결과 한국에 규칙적으로 도래하는 아종은 F. n. narcissina이었으며, 한국 미기록 아종인 F. n. elisae와 F. n. owstoni의 기록을 확인하였다. 황금새 성조 수컷은 아종간 형태적인 차이가 명확하였지만 미성숙한 개체와 암컷 형태를 띠는 개체는 아종간 매우 비슷한 특징을 보였다. 1회 여름깃 수컷의 경우 아종 F. n. narcissina는 월동지에서 부분 깃털갈이를 하여 성조 수컷과 비슷한 반면, 아종 F. n. elisae는 태어난 이듬해 여름까지 깃털갈이를 하지 않아 성조 수컷과 형태적으로 뚜렷이 다르며, 오히려 성조 암컷과 비슷한 특징을 보였다. 이같은 형태적 다양성과 깃털같이 전략의 차이 때문에 한국을 통과하는 개체군의 아종 분류가 매우 어려운 것으로 보인다. 조사기간 중 황금새의 가장 빠른 도래일은 4월 13일, 가장 늦은 도래일은 5월 17일로 나타났으며, 가장 많은 개체수가 통과하는 시기는 4월 하순으로서 2008년 4월 24일에는 14개체가 관찰되었다. 그러나 황금새는 봄철과 달리 가을 남하 시기에는 전혀 관찰되지 않아 봄·가을 이동경로를 달리할 가능성이 있음을 보였다. From April 2005 to May 2008, morphological traits and migratory patterns among the subspecies of the Narcissus Flycatcher (Ficedula narcissina) were studied at Hong Island and Heuksan Island in Korea, and at Iriomote Island in Japan. The regular migrants was F. n. narcissina in Korea, but two unreported subspecies, F. n. elisae and F. n. owstoni were also recorded in Heuksan Island, Korea. In our study, Narcissus Flycatchers were spring migrants observed from 13 April to 17 May, and a total of 14 individuals was recorded as a peak day count on 14 April 2008. However, there was no record in the autumn migratory seasons in Korea. This result suggests that the Narcissus Flycatcher is probably an elliptical migratory species which uses different routes in spring northward and autumn southward migrations. In morphology, adult males had distinct morphological differences, but immature and female-typed individuals had very similar plumages among subspecies. First summer F. n. narcissina underwent partial moults in wintering places and became very similar in appearance to adult males. In 'contrast, because F. n. elisae does not undergo partial moults until the summer of the 2nd calendar year, immature males of F. n. elisae were very resemble not adult males but adult females in appearance. Such morphological variances and differences in moulting strategies among subspecies often prevented the identification of Narcissus Flycatchers to the subspecies level.

In this study, homogenized suspension polymerization of methyl methacrylate(MMA) using poly (vinyl- alcohol) (PVA) as suspension stabilizer and benzoyl peroxide(BPO) as initiator was carried out with various polymerization variables. Particle size, distribution, exothermic peak according to the polymerization condition were observed. Particle size of 5~80㎛ was prepared via homogenized suspension polymerization. Particle size was influenced by the concentration of suspension stabilizer and homogenizer speeds. The average particle diameter decreased with PVA concentration and homogenizer speeds, and increased with BPO concentration. Exothermic peak was also influenced by the stirring speed, concentration of suspension stabilizer and initiator.

The use of digital imaging technique and digital contents based on internet has grown rapidly for last several years, and the needs of digital image protection become more important. For the purpose of copyright protection on digital image, the verification of authentication techniques like content authentication, ownership authentication, illegal copy and etc are needed. Digital watermarking, the invisible encryption technique to insert digital watermark into image, the sophisticated perceptual information should be used for providing transparency and robustness of images on watermarking process. In this paper, we implement the algorithm for preventing forged attack, ownership protection and authentication by transforming the wavelet algorithms in frequency domain in terms of human visual system.

Due to the congestion of the reinforcement, it is difficult to arrange properly 2-layer tension reinforcement at the beam-column joint. In ACI and Eurocode, it is recommended to distribute the tension reinforcement within the effective width of flange uniformly to control flexural cracks. In this study, it is conducted a nonlinear analysis of beam-to-column joints using ANSYS to evaluate the ultimate strength and the general behavior of the joints. It is compare to arrange 2-layer tension reinforcement within rectangular section with single-layered tension reinforcement at the beam flange. Based on the results of this analysis, the following conclusion can be drawn : 1. The load-displacement curves of the models were very similar to below 3㎜. That is, the ultimate strength of the model is no difference between arranging 2-layer tension reinforcement within rectangular section and single-layered tension reinforcement at the beam flange at the below 85% of ultimate strength. 2. For the single-layered tension reinforcement it is recommended to provide additional reinforcement at the beam-column joint to attain ultimate load capacity equal to the 2-layered case.

Distributions of deep levels are studied in the n-type Si wafer which are introduced during fabrication with e-beam deposition by using DLTS technique. Test is carried out on the Schottky diode. Metalization of the diode is done by e-beam deposition before of after electron irradiation. Deep levels of the defects are measured by using various metal such as Pd/Au, Au, Pd, Ti, Mo and Hf, and by changing the annealing temperature. It is approved that some defects are introduced in the neighbor of interface of silicon and metal by e-beam deposition, and main defect of them is E(0.42) level. In the resuts, two types of the deep level are observed ; one type is that is independent of electron irradiation, for example, E(0.42) level which is observed near the interface ; another type is that is observed only in the diode deposited by e-beam after electron irradiation, for example, E(0.18) level and so on which are observed farther from the interface. It may be the reason that interaction is presented between defects from Pd, at least, and prior defects.
