This study is to discuss the content of Posangkimun on the whole and to report the understanding of Seokgok Lee Gyujoon on western civilization. Through the overall analysis of Posangkimun, it is found the following facts: 1. Posangkimun aroused interest of academic circles as it covered theories of western civilization. Most of the introduction to western civilization contained in the book is related to astronomy and geography. Seokgok criticized all the western theories on revolution of the earth, astronomy, continents and oceans on the ground that these theories were not congruous with the teaching of the Oriental sages. 2. Seokgok found the reasons why the West had led the East from 'nationalism' of the West. The nationalism mentioned here were more similar to 'democracy' in modern sense, or rather 'democratism'. What is specially noteworthy is that he did not find the reasons of western advancement from the spiritual issues not from the machine civilization. In this way, Seokgok could avoid the fallacy of throwing away traditional ideas to concentrate in western machine civilization. 3. The content of Posangkimun shows that Seokgok was a person with a very conservative view. Notwithstanding his inclination, he had good knowledge about western theories, most of which were gathered from newspapers and magazines at that time. It means that newspapers and magazines should be treated with more importance when studying Korean intellectuals in late Joseon period or during the time of Japanese forced occupation.

Research on Seokgok(石谷), Lee Gyu Jun(李圭晙, 1855~1923)'s thought and medicine was progressed from various angles. There is no research on Chinese poem(漢詩) accounting for the half of his collection of literary works, "Seokgoksango(石谷散稿)" yet. Hence, the article reviewed concerns on his life and what life he lived as a Confusion(儒家) writer through his Chinese poem. Should read "Seokgoksango", Seokgok's spiritual orientation and attitude to life were found to have its core in the Confusion(儒家的), especially ethical(道學的) aspect. Seokgok's Chinese poem materialized his spiritual composition more, able to access up to general emotional state, representing concerns and frustration of intellectuals in the latter era of the Choson Dynasty. Anxiety consciousness(憂患) of patriotism and love of the people which traditional intellectuals implicated enough at the turbulent era of early modern time appeared strongly in his works. Also works seeking for devotion(歸依) toward the clean world(淸明世界) staring at the corrupt world losing the national sovereignty at the same time and the expansion(擴散) was able to be found many. The latter half of the 19th century and the early 20th century when Seokgok lived was the period of changeover in the history of civilization called intersection between traditional era and modern times. His Chinese poem showed traditional intellectuals' anxiety, frustration, conflict, and hope based on such times. Along with the status of an Oriental, medical doctor and thinker, up to discussion on the quality of a writer, the intensified research on him is expected.

Accroding to "Hwangjenaegyeong(黃帝內經)", when the food and drink[水穀] enter the mouth, they divided into two different things with solid food[食] and liquid food[飮], then transformed and absorbed into Jeong(精), Gi(氣), and Jinaek(津液) and spread to the entire body. The movement and transformation[運化] of the food and drink in the body can be distinctly described with the circulation of the Yeonggi(營氣) Wigi(衛氣) and metabolism of Jinaek. The leftover food[糟粕] which is not transformed into Jinaek, not delivered to the Jangbu(藏府) like Gan(肝), Shim(心), Bi(脾) and Pe(肺), brought to the Daejang(大腸) and transported through the baekmun(魄門). Or some of them are verified at the Hoejang(廻腸) and brought to the Banggwang(膀胱) through the Hacho(下焦) then transpired them outside the body. The distinguishing mark of the movement and transformation of the food and drink and its transpiration in the "Hwangjenaegyeong" is that the Sin(腎) of five jangs is exclude from the process of the movement and transformation and the process is explained with the fluid like Gi and Jinaek. From the "Nangyeong(難經)", developing of Myeongmun(命門) theory, the importance of the Sin in the delivering process of the food and drink is remarkably highlighted; however in the late period of Chosun dynasty(朝鮮), Seokgok Igyujun(石谷 李奎晙) denied the temporary theory of Myongmun and asserted the original interpretation recovery of "Hwangjenaegyeong".

During the period of 1975-76, a survey was carried out to find out zinc indicators in the natural vegetation in Korea. The symptoms fo chlorosis were observed in flowering plants in the areas of zinc outcrop of Wolgok-A, Seokgok-9, and Sowolgok. Although 28 species were found to be chlorotic, the total quantity of chlorotic foliage observed was small. Reasons for chlorosis in the areas of zinc are deposits is considered as effects of zinc, lead, copper and calcium ions. Sedum sp. and Dianthus sinensis were confined to soil containing more than exchangeable zinc of 30 ppm and to accumulation in the plants contained at least 1,300-14,000 ppm of zinc. Therefore Sedum sp. and Dianthus sinensis might be used as zinc indicators in Korea.

On June 14, 2008 (the first experiment) and July 24, 2008 (the second experiment), the shores of the Boseong River and the sandy beaches, Seokgok-myun, Moksadong-myun, Gokseong-gun in Jeollanam Province were investigated and a total of 29 soft-shelled turtle (Tryonyx sinensis) eggs in the natural spawning nest eggs were collected (13 eggs were collected in the first experiment and 16 eggs in the second experiment). The temperatures in the natural spawning nests were $25.9-36.9{\pm}0.5^{\circ}C$, the depth of the eggs was $5.2-7.5{\pm}0.5cm$ as the distance of the average $6.4{\pm}0.5cm$. 29 eggs were scattered at least 0.2 cm interval. Artificial incubation of 29 eggs was conducted in artificial nest boxes in thermo-plastic composition of the incubator, and then incubated at $26.5-35.5{\pm}0.5^{\circ}C$, and an average constant temperature was $31.2-32.1{\pm}1.0^{\circ}C$. The incubation days ranged from 53 to 55. In case of most turtles, incubation at $31^{\circ}C$ (higher temperatures) generally produces all or mostly females, while incubation at $25^{\circ}C$(cooler temperatures) produces all or mostly males. Exceptionally, in case of genus Trionyx, the sex ratio of female : male of T. sinensis of a freshwater soft-shelled turtle was approximately 1:1, which differs from other genera of turtles and makes T. sinensis Strauch only turtles presently known to lack temperature-dependent sex determination.

130종의 식물성 한약재 열수 추출물의 항산화활성 및 세포에 대한 항변이원성과의 관련성을 조사하였다. 항산화활성은 DPPH 자유라디칼에 대한 전자공여능 및 Fenton반응에 의해서 생성되는 hydroxyl radical$({\cdot}OH)$ 소거능을 각각 측정하였다. 조사한 대다수의 한약재들이 전자공여능 및 ${\cdot}OH$ 소거능을 가지고 있었는데, DPPH 자유라디칼에 대한 전자공여능이 가장 큰 한약재는 필발(Piper longum L.)이었으며, ${\cdot}OH$ 소거능이 가장 큰 한약재는 석곡(Dendrobium moniliforme L.)이었다. 항산화활성의 측정 결과, 전자공여능 및 ${\cdot}OH$ 소거능이 대조구에 비하여 모두 50% 이상이 되는 항산화 효과가 큰 한약재는 지모(Anemarrhena asphodeloides Bunge)를 포함하여 24종 이었다. 항변이원성을 뚜렷하게 나타내는 11종의 한약재가 $Cu^{2+}$ 존재 하에서 DNA의 손상이 유도될 수 없는지 여부를 조사한 결과, 택사(Alisma canaliculatum All. Br.)와 백자인(Nitraria sibirica Pall), 오약[Lindera strychifolia (Sieb. et Zucc) Villar]을 제외한 모든 시료에 의하여 DNA의 손상이 일어난다는 사실을 알았다. 또한 택사와 백자인은 화학적 돌연변이원인 mitomycin C가 유발하는 DNA손상도 강하게 억제함을 확인하였다.

하천 습지에서 생육하는 식물 군락의 분포와 생물과 비생물적 환경요인과의 관계를 분석하기 위해서 보성강내 하천 습지에서 식물 군락과 환경요인을 조사하였다. 연구장소인 보성강 하천 습지는 화평습지, 반구정습지, 석곡습지로 구성되어 있다. 2022년 6월부터 9월까지 상관식생적 관점에서 식물군락 조사를 수행하였고 출현종의 피도는 Braun-Blanquet scale을 따랐다. 식물 군락 조사를 위한 방형구내에서 식물종과 각 종의 피도를 기록하였고 생물 요인으로 방형구 울폐도, 총 출현 종수, 외래종 수를 측정하였다. 비생물 요인으로는 고도, 방위, 경사도, 토성, litter 층 깊이, 우점종 흉고직경, 지형을 기록하였다. 총 50개의 방형구에서 버드나무와 달뿌리풀 군락이 가장 많이 발견되었고 Shannon 종다양도 지수가 가장 큰 군락은 달뿌리풀-물피 군락이었다. DCCA에 의한 서열법 분석 결과, 하천제방, 제방사면, 상부고수부지권, 하부고수부지권, 고수변부, 수변부, 저수변부, 사주, 하중도, 개방수역 등 지형 요인에 의하여 가장 유의하게 군락이 분리되었다. 하천 습지에서 보전되어야 하는 희귀식물로서 자라풀과 낙지다리는 저수변부에서 발견되어 털물참새피 같은 생태계교란식물의 지형적 분포와 일치하여 저수변부의 하천 관리가 필요함이 밝혀졌다.
