Tasan Jeong Yak-yong is great scholar, who makes a synthesis of Sil-hak[實學, Practical Science of Korea], reformer of society, and a poet in the Joseon Dynasty. He expressed contradiction and conflict of those days by intellectual language, and reperceived basic ideology of the Joseon society. Also he theorized dissatisfaction of the people about those days and its system as form of religion. We can divide Tasan's life into two times. The first part is his ages 16~39 in the period of Jeong-jo(1777~1800). The second part is in the period of Sun-jo(1801~1834). In this period, he was exiled into Gang-jin for 17 years. After banishment, he lived a quiet life for the rest of his life in his hometown. His allegoric poetry were written in this second period. The special feature of allegoric poetry is strong satire. An allegory would be that is 'king's ear', which the barber has sight, or the barber's voice, which has divulged king's secret among the bamboos. Otherwise it would be that is the sound 'king's ear is donkey's ear' in the bamboos. This sound is divulging of the true donkey's ear. It doesn't travel to audiences, but travels trough wind in the bamboos. The narration exists just as story that barber can't stand to keep silence about king's secret. There are exposure of true and critical motive as allegoric expression. Tasan's allegoric poetry stand on the basis of his love for the people. Also there reveals his thought deeply with an enormous amount of reading and self-communion. Moreover there are his warm mind with his sharp insight in which captures alive lives as allegoric materials. Most of allegoric poetry satirize actuality of those days to make an excuse for external distinguishing marks of animals and plants. However Tasan's poetry are different from them. After he grasped serious problems from his contemporary actuality, and then choosed allegoric media to express correctly. Because he grasped the special features of lives after minute observation, he could exposure controversial point of the actual. His sharp insight was not limited to allegoric media. He noticed his period and the current of his society sensitively. It made his allegoric poetry as important materials to make us to know the condition of the people in the Joseon Dynasty. Tasan's allegoric poetry is inherited by Baek Seok[白石, 1912~1995] as regular juvenile literature. Baek Seok's juvenile stories are the results of expansion and transition for Tasan's allegoric poetry. Allegoric poetry was the shout of barber to prosecute about social irregularities and contradiction, and the sound of the bamboos to travel moaning of the people in the past. Now allegoric poetry create new emotion to make us to speculate ourselves with our surrounding. This changes are caused by special feature of allegoric poetry as a form to reflect our general lives.

Carbonization characteristics of Indonesian bamboos were investigated using lab-scale tube furnace, in order to find optimum design temperature of a carbonizer for producing bamboo charcoal and vinegar. The bamboo samples used in this study are local bamboos from Damyang in Korea, Andong and Petung in Indonesia. Correlation of electric resistance, specific surface area and pH of bamboo vinegar with pyrolysis temperature has been investigated. Electric resistance of the charcoal increased for higher pyrolysis temperature the specific surface area was also increased as carbonization temperature got higher. Charcoal which has specific surface area of over $300\;m^2/g$ could be produced at $700^{\circ}C$. pH of bamboo vinegar was decreased for highter carbonization temperature and vinegar under pH 3 could be produced for all bamboo samples. In this experimental condition, it was found that lower carbonization temperature is better for producing bamboo vinegar of high quality, while higher temperature is better for obtaining bamboo charcoal with larger surface.

본 연구는 약 40년 전 식재된 왕대와 솜대를 대상으로 지상부 바이오매스의 기관별 양분 분포를 조사하기 위하여 실시하였다. 대나무 줄기, 가지, 잎에 양분 분포 비교를 위해 왕대 및 솜대 각 14본(당년생과 다년생 각 7본)을 선정하여 벌채하고 양분 분석을 실시하였다. 대나무 줄기, 가지, 잎에 양분 농도(concentration) 중 마그네슘은 솜대에 비해 왕대가 높았으며, 질소, 인, 칼륨은 당년생 대나무가 다년생 대나무에 비해 유의적으로 높은 농도를 보였다. 양분 농도의 크기는 잎에 경우 탄소 > 칼륨 >= 질소 > 인 >= 칼슘 >= 마그네슘 순이었다. 줄기, 가지, 잎에 저장된 총 양분 함량(content)의 경우 왕대가 솜대에 비해 높아, 왕대가 솜대에 비해 양분 요구량이 크게 나타났다. 지상부 바이오매스의 양분 함량 크기는 왕대와 솜대 모두 탄소 > 칼륨 > 질소 > 인 > 칼슘 >= 마그네슘 순으로 두 대나무가 같은 경향을 보였다. 본 연구 결과에 따르면, 유사한 입지에 생육하는 왕대와 솜대의 경우 양분 함량에 차이를 보였으며, 양분 요구량은 왕대가 솜대에 비해 높게 나타났다.

이 논문에서는 우리나라 적지적수 연구사에 관한 사료를 제시하였다. 필자는 조선시대의 임금에 대한 진상을 목적으로 한 적지적수사와 일제강점 초기의 간이적인 적지적수 연구 및 실시사례, 강점중기에 이르러서는 조선수목죽류 기후상적지도, 후기에는 속성수의 절지식재시험 및 지역별 조림수종 선발시험 등에 관한 주요 자료를 해외에서 수집 발굴하였다. 조선수목죽류 기후상적지도는 아직까지 국내에 알려지지 않은 자료로서 향후 우리나라 산지의 지원화 및 산불 피해지 복구조림, 남북통일을 대비한 북한지역 녹화사업의 기초자료로서 뿐만 아니라 고유임상 및 식생연구 등에도 유용하게 사용될 것으로 기대된다.

Fiber morphology and basic characteristics of Legi bamboos (Gigantochloa atter) growing on Yogyakarta were studied considering their age and height positions in the culms. Culms of 4, 16, and 40 months were harvested, and their total lengths were measured. The length, diameter, and wall thickness of each internode were measured. All the sample culms were divided into three different parts along the height, and their fiber dimension and physical properties were observed. The data obtained were analyzed by analysis of variance. The results showed that the culms had a diameter of 5.8 to 10.8 cm. The lowest internodes always showed the shortest length and the thickest wall. The culms had an average fiber length of 2.41 mm and Runkel ratio of 0.61. Fiber length was affected by the height, while fiber diameter, lumen diameter, and fiber wall thickness were affected significantly by the age of the culms. The culms had high green moisture content (GMC) of 157.89%, and basic density (BD) of $456.67kg.m^{-3}$, a total longitudinal shrinkage of 0.35%, and relatively low R/T shrinkage ratio. The interactions between age and height were affected GMC and BD.

The culture and society environment plays major role in the development of Fashion and now in the 21st century, interest in Fashion is getting increased along with the rapid progress of advanced media development and information surge. Now it s the time to extend visual efficiency not only transmitting fashion image but also develop a creative product that satisfy the demander s needs. Currently it is very hard to express our subjective Korean "nationalism" in the Fashion since the various expression skill using western fashion illustration are dominant in our society. I have classified two components, fashion illustration and Korean painting in the theoretical circumstance. In fashion illustration circumstance, I examined the concept, usage, expression skill and history referring to historical documents. In Korean painting section, I considered coloring portrait concept, pattern, history, concept, and feature of the four gentlemanly plants. including the basic material of Korean-paper, Writing- Brush, Ink-Stone, Traditional-ink and also the history of itself. I have designed 8 products applying the concept of plum blossoms, orchids, chrysanthemums and bamboos that represent the most important part of the four gentlemanly plants, and also the expression skill of Korean coloring portrait.rait.

To develop potential cosmetic ingredients with antimicrobial and antioxidant activities of 4 Korean bamboo species (P. bambusoides, P. nigra var. henonis, P. pubescens and Sasa coreana) using three different extraction methods-water, ethanol and supercritical fluid extraction. Antimicrobial activities and DPPH assay have been examined. Among the antimicrobial activities against two test strains, Escherichia coli and Staphylococcus aureus, ethanol extracts of 3 bamboo trees, P. bambusoides, P. nigra var. henonis, and P. pubescens, showed stronger than those of supercritical extracts. However, 4 bamboo supercritical extracts showed dose-dependent increase in antioxidant activity by DPPH assay. These results suggest that water fraction of bamboo extracts may be useful for the cosmetic ingredient with low cytotoxicity.
