  • The seasonal distribution of Maurolicus muelleri eggs and larvae were determined using samples collected from the Korea Strait and the southern part of the East Sea in May and November, 1992, August, 1993, and January, 1994. The eggs were most abundant in summer and the larvae in spring, while, their abundance was low in winter. The eggs were mainly found from in all season around sea of the front area of latitude $35{\sim}36^{\circ}N$ and the West Channel of the Korea Strait found the middle or bottom water lower than $15^{\circ}C$. The seasonal distribution of the eggs in the western Korea Strait varied according to the structure of the bottom cold water of the Korea Strait. The M. muelleri larvae in different stage were most abundant in the front area of latitude $35{\sim}36^{\circ}N$. The spawning and hatching area of the M. muelleri was considered to be the front area located in the shelf break, and some eggs can be transported into the Korea Strait by westward cold bottom current in summer. The Korea Strait would be the southern margin of the distribution of Maurolicus muelleri eggs and larvae of the East Sea.

  • This paper describes a trans-admittance scanner for breast cancer detection. A FPGA-based sinusoidal waveform generator produces a constant voltage. The voltage is applied between a hand-held electrode and a scan probe placed on the breast. The scan probe contains an 8x8 array of electrodes that are kept at the ground potential. Multi-channel precision digital ammeters using the phase-sensitive demodulation technique were developed to measure the exit current from each electrode in the array. Different regions of the breast are scanned by moving the probe on the breast. We could get trans-admittance images of resistor and saline phantoms with an anomaly inside. The images provided the information on the depth and location of the anomaly. In future studies, we need to improve the accuracy through a better calibration method. We plan to test the scanner's ability to detect a cancer lesion inside the human breast.

  • Fish community in the Hoengseong Reservoir was investigated from April to October 2005. The total number of fish caught from the period was 8,626 fish representing 22 species and 8 families, using tyke net and trammel net. Besides biomass was 122.9 kg. In the fyke net, 8,168 individuals caught during the period represented 21 species belonged to 8 families, its biomass was 90.6 kg. On the other hand, 458 individuals caught in the trammel net during the period represented 16species belonged to 6 families, its biomass was 26.3 kg. The results showed that the trammel net had lower number of species, individuals, and less biomass compared to those of the tyke net. Number of species confirmed was increased according as mesh size of the net was smaller. Besides, the fyke net with small mesh size was able to collect not only small-sized fish but also large-sized fish so that it was suitable to study qualitative and quantitative analysis of fish fauna in detail. Whereas, the trammel net with proper mesh size was effective to determine composition of fish species in the studied area.

  • The purpose of this study is about to consider the structure of dualistic recognition between "Gang-Ho"(ideal sanctuary) and real world in the "Songs of Fisherman" written by Lee Hyeon Bo. In order to do this job, I analized the arrangement of the contents and extract the exact in and outward meaning of elements and expressions; usage of them between lines of this Song. Based on these works, I tried to explain the confronted recognitions of the two worlds. At the first, about the arrangement and contents of this poem, It is consisted of 5 independent sub-poems and each of them are describing the value of fisherman's life(at the poem 가), separation from mundane world(나), satisfaction of fisherman's life(다), nature of "Gnag-Ho"(라), domiciliation in the place(마). It looks like that the writer intended to have the arrangement probability and likelihood connecting poems. Secondly, It contrast the nature of the "Gang-Ho" and real world. The sanctuary is a place of 'absence of worldly desire' and 'cordiality' that could afford one's harmonious life. On the other hand, the real world is a troublesome place which always conflicts political confrontations. For those reasons, the writer wants to satisfy with his living in "Gang-Ho" separating himself from the real world. Thirdly, The nature of "Gang-Ho" is 'absence of worldly desire' and 'cordiality' that one could be deserved his diligency becoming a part of the harmonious idealistic living place. Fourthly, on the character of story teller. Originally he is a incomer of "Gang-Ho" from real world. so that reason, he is showing dualism not to deny the loyalty oath to his king, while he intends to satisfy with the life in "Gang- Ho" separating himself from real world. As a gentry, at that time, the loyalty oath is inevitable one and that is found from writer's other works either. Fifthly, Characters of the different world recognition. The main reason of his intention to "Gang-Ho" roots on out of worldly confrontations, his separation from real world is on a joyous peaceful life just like in "Gang-Ho". this study believes the writer imply that 'absence of worldly desire' and 'cordiality' of "Gang-Ho", be a key role to resolve the confrontation of real world. Lee Hyeon Bo himself regards the two elements as a advisable attitude of life. At last, Seeing the writer's other work and literature's educational effect, this study defines that even if the poem outwardly express one's lyricism but inside it warns governors ruling attitude.

  • The aim of this study is to see how bamboo paintings developed and what is the iconographical meaning of them through bamboo Ti-hua-shi(poems on paintings) found in Sheng-Hua-Ji, a leading compilation of Ti-hua-shi(poems on paintings) of Song Dynasty. Bamboo paintings give shapes in a simpler and more direct way in drawing, which means bamboo paintings reveal concretely more characteristics of Ti-hua-shi (poems on paintings). Bamboo paintings, which flourished during Northern Song Dynasty, often had the image of the dragon, specially a lying dragon or a winding dragon, which suggests a great man in obscurity. Snow-laden bamboos were also a symbol of a great man, very wise man in Confucian tradition. This shows Confucian ideal examples were embodied through bamboo paintings. Another aspect of bamboo paintings is that bamboo paintings were regarded as a means of self-expression, which identified Confucian sadaebu (scholar-officials) who advocated simplicity and austerity in their life. Contrary to professional painters, who added color and decoration to their paintings, Confucian scholars of Song Dynasty reduced color and embellishment in their bamboo paintings in black-and-white to reveal their own identity, focusing on spirituality rather than the image itself. Therefore, drawing and appreciating bamboo paintings were highly respectable pastime among the literati of Song Dynasty. In short, Bamboo paintings in Song Dynasty were not only a Confucian symbol of a wise and virtuous man but also reflected the taste of Song sadaebu class who thought of bamboo as a symbol for moral and cultural responsibility of Confucian society.

  • As the public Japanese art, print can be said to have started from Ukiyo-e print of Edo period(江戶時代, 1603~1867). Ukiyo-e(浮世繪) print, which 3 persons jointly produce, henceforth has gradually declined since the meiji period(明治時代, 1868~1912) due to the development of new print technique and introduction of western art. Since then, during the daiso period(大正時代 1912~1926), creative print movement grew up. Creative print is, differently from Ukiyo-e print, to be produced by one person, from the original picture to print, focusing on creating the artist's own work by being the main agent of the work. During before and after 1900s, print was evaluated low in Japan, compared to western painting, sculpture, etc. Nevertheless, the facts that several Japanese print artists received awards from international exhibits since 1950s became a big topic internationally, which became an opportunity to hold Tokyo International Print Biennale in 1957 in Japan, the first international art festival. From then on, print was recognized as an art genre while new recognition on it was gradually accepted also in Japan. In 1970, a controversy on it arose, while the characteristic of print as a medium of modern art became strong, accordingly, a controversy on it arose. However, in 1980, it firmly established itself as an art genre by overcoming the crisis through various efforts in the dimension of print artists and university education. Since then, print artists who produce new works with completeness by applying traditional technique and modern expression mode emerged, and until now Japanese modern print art is highly recognized by the world through the continuous overseas activities, research on print art, and cultivation of young print artists. This research looked back on the historical process when Japanese modern print art was created, which represents Asia, and investigated the cause that it could have win an international fame.
