인천시 무의도 습지 주변에 분포하는 관속식물의 현황과 분포특성을 파악하였다. 무의도 습지의 식생은 2개의 군락군과 6개의 군락으로 구분되었다. 습지 내에는 땅귀개-흰개수염 군락군으로 대표되며 2개의 군락(고양이수염군락과 갈대군락)이 분포하였고 습지 주변에는 오리나무 군락군으로 대표되며 4개의 군락(진퍼리새군락, 쇠보리군락, 졸참나무군락, 리기다소나무-억새군락)으로 구분되었다. 관속식물의 종류조성은 30과 53속 50종 8변종, 총 58분류군이며, 그중 피자식물이 주축을 이루고 있음을 알 수 있다. 이들 중 한국특산식물이 관찰되지 않았으며, 산림청이 지정한 희귀 및 멸종위기종은 땅귀개와 이삭귀개, 2분류군으로 조사되었다. 귀화식물은 아까시나무, 1분류군만이 관찰되었다. 환경부의 식물구계학적 특정식물종은 V등급이 땅귀개와 이삭귀개 등 2분류군, II등급은 돌양지꽃, I등급은 굴참나무와 애기쉽싸리 등 2분류군이 조사되었다. 소산식물의 생활형을 보면, 수생식물이 전체의 20.7%인 12종류로 가장 많았으며 1년생식물은 1종류만이 관찰되었다. 무의도의 marsh형 습지는 다양한 습지식물이 분포하며, 식충식물인 땅귀개와 이삭귀개가 우점하고 물이끼가 분포하는 것으로 보아 Bog(산성습원)형태로 진행 중인 습지로 판단된다. 습지의 주변은 인간간섭에 의한 훼손이 발생하고 있으므로 시급한 보전대책이 있어야 하겠다.

This study was conducted to investigate the effect of microbial liquid manure(MLM) on the growth and yield characteristics of Altari radish ( Raphanus sativus L.). MLM 1,000㎎ㆍL⁻¹, MLM 2,000㎎ㆍL⁻¹ and MLM 1,000㎎ㆍL⁻¹+microbial fermentation compost(MFC) 600㎏/10a were treated. MLM was sprayed on leaves at 10, 20, and 40 days after planting. Leaf length and width of radish in all microbial fertilizer treatments were more vigorous than that of control significantly. Number of leaves was great in order of 1,000 ㎎ㆍL⁻¹ MLM+600㎏/10a MFC ＞ 2,000㎎ㆍL⁻¹ MLM ＞ 1,000㎎ㆍL⁻¹ MLM. SPAD reading value was increased with treatments of 2,000㎎ㆍL⁻¹ MLM and 1,000㎎ㆍL⁻¹ MLM+600㎏/10a MFC. Root length and weight of all the microbial fertilizer treatments tended to increase compared with control, and 1,000㎎ㆍL⁻¹ MLM+600㎏/10a MFC treatment was the most effective.

Soe-gye(西溪) Pak Tae-Moo(朴泰茂) was one of the famours scholars who lived in the right side of Kyungsang province in the 18th century. After the restoration in 1623 the scoholastic trend in this area was desprited with party strifes. He declined all of the successful career, and concentrated his mind on expounding his scolarship based on the Newcofucianism. He devoted himself to studying and practicing sacred books to cultivate his mind. His scholarship intended to keep his principles to establish firm faith for the spritual culture. His principles for the spritual culture could be summrized as the diagram and inscription of Jagyungbyung[自警屛]. The diagram and inscription of Jagyungbyung could be seen as the most representative summary of his scholarship, which he focused in two fundamental concepts Sung[誠] and Kyung[敬]. Soe-gye's interest in endeavoring at self-cultivation was succeeded to the scholarstic mentle originated in Namymung[南冥] and his forefather Pak-Min(朴敏) who was one of the followers of Nammyung and one of the friends of Misu[眉叟]. In partcular he attached much importance to Simhakdo[心學圖]. In this point Soe-gye's scholarship for the spritual culture shows a marked trend toward practical ethics[心學] originated in Namymung school. His discussion for self-cultivation in the rouhly based on the dilatation and interpretation of the typical articals of Sungrijulyo[性理節要], but by the way he successfuly explained the purpose and the prescription for self-cultivation.

This study was carried out to investigate the effects of natural materials on quality and yield of radish. The GB10, chitofarm, chaff charcoal, and chaff charcoal sap were used as natural materials. The total plant weight, root weight, root length, and root width of radish in treatment with natural materials showed significant difference compared with control. The yield of radish in 1% of GB₁₀ treatment was increased 75% compared with control. The chemical components were increased in total plant of radish treated with natural materials compared with control. This appears that natural materials increase the quality of radish.
