Many people have a growing interest on the health result from economic improvement, various environimental pollution and stress, and unrest on the adult diseases etc.In these result, demand for the herb medicine continues to expand. Farmers of theour country have a hardship in the farm management owing to of opening and liberaliza-tion, and make strenuous efforts on the devclopment of substitute crops to overcomethese differties. Government nowadays recommends the cultivation of the economiccrops like a flowers, medicinal herbs mushroom and clean vegetables. Medicinal herbsare specially profitable among these crops because herbs are possible to culture inwaste land, disused field and slope land, and owing to need less labor and competitionthan those of other crops. The most important problem is the facts that the compli-cation of currency structure of herb medicine inflicts mucll loss to cultivators. Therefore, this study was investigated the state of herb cultivation and the facts to be imploved in currency structure of the harvested herb medicine.1 . The cultivating area and output have been gradually increased and much produc-ted in Kyoungbuk, Kangwon, Choongbuk, Cheonbuk and Cheonnam province in or-der of cultivating area 2. Collection amount of wild herb medicine is decreasig bythe reason of the varous difficulties on the collection. 3. Cultivators of medicinal herbscan make agricultural management more resonable in information exchange on theherb cultivation, purchase of seed, fertilizer, chemicals and other materials, and sell-ing of harvested herb medicine by organization of cultivator fraternity. 4 Cultivatorshave to exclude intermediary margin by the development of direct transaction andcontract cultivation with medicinal herb store, drug manufacturer, chinese meicinehospital and trading firm etc. And also, by the performing exportation with foreign consumer.

This study was conducted to establish a strategy to improve the grafted cacti export which has been stagnated in these year. To promote its exporting, first of all, Korean cactus producer needs to save the cost of labor by using bottom nutriculture system for the greater national competitiveness. Second, it is desired to diversify the export cactus items such as a new variety of Epiphyllum truncatum, big size of perfect brand, a finished package production to satisfy foreigner's demand coping with international market change of grafted cacti. On the other hand, Korean cultivar protection and national negotiation for a reducing tariff rate or an efficient plant inspection system are also needed.

To provide the basic information on the excavation, conservation, and systematic management plan for preservation of valuable forested wetlands, a field survey was analyzed at public and private forests in Daegu city, 2010. The expected points of FGIS were identified, and buffer zones for the protection of forested wetlands were derived. According to the results from the 11 points of forested wetland, the flora of wetlands in Daegu city were consisted of a total of 169 taxa; 63 families, 131 genera, 148 species, 2 subspecies, 14 varieties, and 5 forms. The species diversity of shrubs in forest wetlands was highest at 1.560, and the evenness was highest in shrub trees at 0.913. Considering the type of wetland, topography, etc., the buffer zone was set at 20~50m from the core area boundary.

Barley's nutritional value as a health food is increasing due to its excellent nutritional functionality. In this study, the levels of β-glucan, total polyphenols, and total flavonoids were analyzed in the ethanol extracts of different barley cultivars (Hinchalssal, Heuksoojeongchal, Betaone, Ganghochung, and Saechalssal). Also, the free radical scavenging abilities of 2,2-diphenyl-1-picryl-hydrazil (DPPH) and 2,2'-azino-bis-3-ethylbenzo-thiaxoline-6-sulfonic acid (ABTS) were measured to determine their antioxidant activity. The results confirmed that Betaone extract contained highly activefunctional components and exhibitedantioxidant activity. Next, we evaluated the hepatoprotective and inhibitory effects of reactive oxygen species (ROS) generated by barley ethanol extracts after inducing oxidative stress with tert-butyl hydroperoxide (tBHP) in HepG2 cells. Hinchalssal and Saechalssal extracts showed the most significant cytoprotective effect and also reduced ROS production significantly. These results suggest that Hinchalssal, Saechalssal, and Betaone represent potential natural antioxidant and hepatoprotective agents.

Although the breed protection rights of Jangsaemi garlic were registered in 2012, the cultivation area was not large and no related papers were found, so this study was conducted. Potassium was the highest inorganic content of Jangsaemi garlic, followed by nitrogen, sulfur, and phosphorus. Allin and allicin were also present at 9.73±0.97 and 1.65±0.15 mg/g, respectively. The solid content was 7.90±0.00°Bx, and the reducing sugar was 33.42±1.79 mg GE/g. The total phenol and flavonoid contents were 80.35±2.67 mg GAE/100 g and 33.80±2.17 mg QE/100 g, respectively. The antibacterial activity of Jangsaemi garlic was higher in gram-positive bacteria than in gram-negative bacteria, especially Staphylococcus epidermidis and Micrococcus luteus. The results of these studies are expected to provide useful information for farmers growing Jangsaemi garlic in the future.

비무장지대(DMZ)는 군사적 활동 외에 일반인에 의한 접근이 엄격히 통제되어 자연적으로 생물들이 보호되어 왔으며, 한반도의 거대한 동 서 생태축으로서 그 중요성이 매우 높다. 본 연구는 경기도 연천군지역의 비무장지대 및 민통선지역에 분포하는 자원식물의 현황을 파악하고 희귀식물, 한국특산식물 등 주요 유용자원식물의 보전과 관리에 기초자료를 제공하고자 실시하였다. 연구대상지에 분포하는 자원식물은 74과 168속 192종 4아종 26변종 5품종으로 총 227분류군으로 우리나라에 분포하는 관속식물 4,881(국립수목원, 2007)분류군의 4.66%로 나타났다. 각 과별 구성종의 출현비율을 살펴보면 국화과 36분류군으로 가장 다양하게 출현하였다. 연구대상지내에 분포하는 희귀식물은 쥐방울덩굴(Aristolochia contorta Bunge)로 1분류군이 확인되었으며, 한국특산식물은 키버들(Salix koriyanagi Kimura), 병꽃나무(Weigela subsessilis (Nakai) L.H.Bailey), 은사시나무(Populus tomentiglandulosa T. B. Lee)로 3분류군, 귀화식물은 단풍잎돼지풀(Ambrosia trifida L.), 족제비싸리(Amorpha fruticosa L.), 아까시나무(Robinia pseudoacacia L.) 등 등 17분류군으로 나타났다. 연구결과 전체적으로 다양한 식물종이 확인되지는 않았으며, 일부 구간에는 가시박(Sicyos angulatus L.), 돼지풀(Ambrosia artemisiifolia L.), 단풍잎돼지풀(Ambrosia trifida L.) 등 생태계교란 야생식물이 폭넓게 분포하고 있는 것을 확인할 수 있었다.
