This study aimed to let people recognize lecture halls and to investigate the short history of Go un Choi Chi -won, an object of enshrinement , to examine the location environments, establishment background and meaning of Jacheondae, Oksan Lecture Hall , Munchang Lecture Hall and Yeomui Lecture Hall located in Gunsan area in Jeollabuk-do. The results concerning the facilities of the said historic sites and the arrangement of trees could be summarized as below. 1. Goun was a person from Silla and studied in Tang Dynasty when he was 12 (in 868) and passed the state examination in 6 years when he was 18 and became a Jinsa (進士) so that people were very surprised at his smartness. At the age of 20, he became a Yunam Jeoldosa (桂南 節度使: military officer) in China and commander in chief of eastem section and was in charge of documentation duties. At that time, the insurgent Hwangso rebelled against the country and Goun became famous for putting down the rebel as a Dochonggyeonggwan (都統警官) . 2. Among 12 remains related to Goun distributed in Jeollabuk-do , 1 pavilion and 3 lecture halls including Jacheondae, Oksan Lecture Hall , Munchang Lecture Hall and Yeomui Lecture Hall in Gunsan’s Okgu area and Jacheondae and Munchang Le cture Hall have been located in Okgu Hyanggyo and Oksan Lecture Hall has been on the right side of Okgu Hyanggyo flanked by a wall. Amogn them, Jacheondae was the place where Choi Chi-won read books when he followed his father who was appointed in Naecho-do as a military officer of Silla during his childhood. Meanwhile， Munchang Lecture Hall, Oksan Lecture Hall and Yeomui Lecture Hall were f ounded by regional Confucian scholars in the reign of Sukjong in Joseon Dynasty (in the heyday of Confucianism) to follow the thought of loyalty and filial piety and lofty knowledge of Choi Chi -won. There many regional competent scholars have been brought up and they have played a large role in doing religious services for ancient sages and in maintaining the Confucian community order. 3. Jacheondae in Okgu-eup was actually located on a hill at Seonyeon-ri and three lecture halls were situated in the flat village with low mountains and they were surrounded by private houses. In terrns of buildings and main planting species, in Munchang Lecture Hall , inner Samun and shrines were arranged in a row. Meanwhile, inner Samun, outer Samun and space for religious services were arranged in a row and education space and managerial sector were in symmetrical form and the space for religious S8rvices was arranged in a rear(a form of building arrangement of Humyojeonhak ) in Oksan Lecture Hall and Yeomui Lecture Hall. In addition, crape myrtle was unique as a planting species and they were planted in symmetrical form in education space and space for religious services

‘고운’은 농촌진흥청 국립식량과학원 고령지농업연구센터에서 가을재배용 칩가공용 품종을 육성하고자 1998년 건물함량이 높은 가공용품종 ‘Lemhi russet’와 수량성이 높은 단휴면 2기작 식용품종인 ‘추백’을 인공교배하여 육성하였다. 그후 봄재배와 가을재배를 통하여 실생세대와 생산력검정예비시험, 생산력검정본시험을 거치면서 H98005-4를 선발하였으며, 2005년과 2006년에 걸쳐 제주, 남해, 강릉 등 3지역에서봄, 가을재배를 통해 지역적응시험을 실시한 결과 그 우수성이 인정되어 2006년 농작물 직무육성 신품종 선정위원회에서국가목록 등재품종으로 선정되었다. ‘고운’은 남부 해안 2기작감자 재배지역에 적응하는 칩가공용 감자품종으로 숙기는중간정도이다. 반직립형으로 생장하며, 꽃색이 흰색이고, 자연조건하에서 열매는 거의 달리지 않는다. 괴경모양이 짧은 계란형으로 육색이 흰색이며, 내외부 생리장해 발생이 적다. 괴경의 건물함량이 높고 환원당 함량이 낮아 칩가공성이 우수하다. 괴경의 휴면기간은 수확후 60～70일 정도이다. 더뎅이병과 역병에 대하여 중도저항성이지만 감자바이러스Y에는 약하기 때문에 씨감자 채종재배시 진딧물 방제를 철저히 하여야한다. 풋마름병에 대해서는 저항성이 없으므로 풋마름병 발생지역에서는 재배하지 말아야 한다. ‘고운’의 수량성은 2005년부터 2006년까지 2년간 실시한 지역적응시험 결과 봄재배시33.2 ton/ha, 가을재배시 26.2 ton/ha로 나타나 ‘Dejima’에 비하여 각각 87%, 86%의 수량성을 보였다. ‘고운’의 적응지역은 전라북도 해안지역과 전라남도와 경상남도의 2기작감자 재배지역이다.
