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.

The Interplay between the Emotional and Rational in Art: a Case Study of Individual Artwork

Jung-Ouk HONG,Hyung gi KIM 중앙대학교 영상콘텐츠융합연구소 2019 TechArt :Journal of Arts and Imaging Science Vol.6 No.2

It is indispensable to bring the sensibility of science (rationality) to interpret the language of art (emotion). On the contrary, the artistic domain has a great influence on the development of science. In the conventions of contemporary civilization, these fields are distinctly divided areas, but in previous generations, they took on very similar shapes. This article was written to explain their correlation when creating individual works. In general, when a painter creates a work, he or she uses a rectangular canvas, yet it is not a prescribed rule. Hong’s artworks began with the transformation of a rectangular canvas and have expanded beyond the plane to space. This extension does not apply only to art. Science also considers it necessary to expand thinking by questioning everything that is unconsciously accepted. Therefore, both the arts and sciences must be expanded to consider questions in all fields.

한국에서 도래하는 황금새(Ficedula narcissina)의 형태적 특징과 이동 양상에 관한 연구

박종길(Jong-Gi1 Park),홍길표(Gil-Pyo Hong),채희영(Hee-Young Chae) 한국조류학회II 2008 한국조류학회지 Vol.15 No.1

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.

Spring network models are being developed to facilitate the analysis and design of structural concrete components and systems. Concrete is represented by rigid particles which are inter-connected by elastic springs. Spring fracture equates to discrete cracking along the particles boundaries. The network geometry is defined by the Voronoi diagram associated with a randomly generated set of points (i.e. nuclei of the Voronoi cells.) These nuclei define the computational degrees of freedom and are distributed so as to maximize isotropy with respect to potential crack direction A novel method is given for calculating stresses in th rigid-particles-spring network. Reinforcement is modeled discretely and can be positioned in the structural model irrespective of the local geometrical features of the network. Concrete-reinforcement interfacial behavior is lumped into nonlinear links positioned along the reinforcing components. Network generation, the positioning of reinforcing components and links, and the assignment of linkage properties are all highly automated. The practicality of this approach is demonstrated through analyses of reinforced concrete deep beam.

홍혜영,최호영,최기운 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.1

The purpose of this study is to evaluate the effectiveness of customized mater cone on apical sealing in various apical size of prepared root canals, that is MAF(Master Apical File) and to know at which apical size the apical leakage is to be significantly reduced using customized master cone. 120 extracted single rooted premolars were divided into four groups according to their apical size(MAF), #30, 40, 50 and 60. And then, each group was subdivided into three in accordance with three obturation methods, lateral condensation with standardized master cone, lateral condensation with chloroform-dipped customized master cone, and continuous wave of obturation technique. Resorcinol-formaldehyde resin was used for the microleakage test of this study. Teeth were sectioned horizontally at 1.5mm(Level 1), 2.5mm(Level 2), and 3.5mm(Level 3) from the anatomical root apex using low speed microtime. All sections were examined under ×40 magnification with a stereomicroscope, photographed, and then scanned. With the scanned images, resin-infiltrated area presenting the microleakage was calculated using SigmaScan/Image, and the ratio of leakage to the total root canal area of each group was analyze statistically(one way ANOVA). The results were as follows ; 1. In groups of MAF #30, there was no significant difference of mean leakage ratio among three obturation methods at all three levels. 2. In groups of MAF #40, thre group using lateral condensation with customized master cone had the lowest mean leakage ratio at all three levels, but there was no significant difference among there obturation techniques. 3. In groups of MAF #50, the mean leakage ratio of the group using lateral condensation with standard master cone was the highest among those of three obturation techniques at level 1, and this difference was statistically significant(p<0.05). 4. In groups of MAF #60, the groups using lateral condensation with standard master cone had also the highest mean leakage ratio at all levels, but there was no significant difference at level 1 and 2. At level 3, the leakage of the group using lateral condensation with standard master cone was significantly higher than that of the group using continuous wave of obturation(p<0.05). The results of this study suggested that the obturation method using customized master cone or the continuous wave of obturation is more effective for apical sealing than that using standardized master cone when MAF is larger than #50.

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.

Recently surmountable amounts of genes are being cloned but it is hard to define the chromosomal location and functions of these genes. In this study, a new technique was developed for cloning genes expressed in the developing human brain with confirmed chromosomal location. The mRNAs were extracted from 18 week old human fetal brain, cDNAs were made by reverse transcription from these mRNAs and Uni-amp cDNAs having Uni-amp adapters a t both ends were made for subsequent PCR. To observe the distribution of the Uni-amp cDNAs on the chromosome, fluorescent in situ hybridization was performed with biotin labeled Uni-amp cDNAs. Among the chromosome bands showing strong hybridization with the cDNAs, lq21, lq25, lq32 and lq42 were microdissected from the chromosome hybridized with unlabeled Uni-amp cDNAs and amplified by PCR with Uni-amp primers. These amplified cDNA fragments were subcloned to plasmid vectors and the nucleic acid sequences were analysed. As a result 18 different clones were confirmed the chromosomal localization. They were categorized as 4 clones of well characterized genes, 3 clones showing low homology with known genes, 5 clones of simply registered uncharacterized human cDNAs, and 6 clones of unknown genes. The evidence suggests that the technique is very useful to clone the genes that express in the developing human brain, with confirmed chromosomal location. In addition, this cloning technique can be used to discover the new genes related with neuronal development in combination with functional screening method.

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.
