In a continuing screening of selected medicinal plants native to Mongolia, the antioxidant and α-glucosidase inhibitory activities of methanol extract of Iris bungei were investigated. After extraction with 80% of methanol, the methanol fraction was further extracted with n-hexane, EtOAc and n-BuOH in order to obtain four different solvent-soluble fractions, namely n-hexane-soluble, EtOAc-soluble, n-BuOH-soluble and H2O residue. The antioxidant properties were evaluated by radical scavenging assay using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS+) radicals. The anti-diabetic efficacy of I. bungei extract was investigated by α-glucosidase assay. All tested samples showed dose-dependent radical scavenging and α-glucosidase inhibitory activities. Among the tested extracts, the EtOAc-soluble fractions showed the greatest radical scavenging activity and α-glucosidase inhibitory properties among other solvent-soluble fractions. This result suggested that there was a significant relationship between the total phenolic content and biological efficacy. Thus, I. bungei extract might be considered as a new potential source of natural antioxidant and as a α-glucosidase inhibitory source. A more systematic investigation of this biomass sill be performed for further investigation of activity against antioxidative and anti-diabetic effects.

This study is aimed at the necessity application in 'Prototype' general concept on discovering cultural identity landscape of our national characteristics landscape research. Accordingly, It is considered landscape, fundamental concept, the prototypal landscape concept from previously researches that have been used. At the same time, the concept of prototypal landscape has been established by commenting a point of view which is defining previous researches that controverted prototypal landscape, then establish concept of prototypal landscape and derive attribute by comparing and considering similar terminology of prototypal landscape. Previously, research prototypal landscape in depth by applying defined concept of prototypal landscape and considering inherence ideological and environmental background prototypal figure and structure. Formation pattern of the prototypal landscape is classified in both philosophical formative primary factor from philosophy, religion and environmental formative factor of human that accumulated cultural life from a region and life. Examples of forming the prototypal landscape by philosophical formative factor are classified as 'Feng-Shui(the theory of divination based on topography)', 'Yin-Yang theory', 'Confucian idea theory' 'Philosophical Taoism', 'Buddhism theory' and 'Nature theory' then environmental formative factor are interpreted by 'Taekliji(determining of advantageous land)', 'Imwon(forest) economical geography', 'land use', 'topography' and 'terrain' as examples. This study is anticipating a new point of view and an establishment of reliable preservation to our characteristic of the prototypal landscape by considering concept of prototypal landscape and formative factor as studying limits of prototypal landscape and researching concentrated origination of the prototype.

This paper was to use choice experiments in the analysis of consumer choice behavior and preferences for five different attributes(the origin of rice, a quality certificate, a quality control, a traceability system, the price of rice) in Cheongju City. Completed surveys yielded 712 responses which were analyzed using the conditional logit model to analyze the marginal willingness to pay of the four attributes(the origin of rice, a quality certificate, a quality control and a traceability system) per household and estimated the marginal willingness to pay of the set of feasible options. The result of this study can be used as a guide for the rice industry in the design of possible labeling schemes.

This study investigated the protective roles and mechanism of magnolol, from the stem bark of Magnolia officinalis against potential neurotoxin 3-hydroxykynurenine (3-HK)-induced neuronal cell death. For the evaluation of protective role of magnolol, we examined cell viability, apoptotic nuclei, change of mitochondrial membrane potential and caspase activity in human neuroblastoma SH-SY5Y cells. It was found that 3-HK induces neuronal cell death in the human neuroblastoma SH-SY5Y cell line. The reduced cell viability produced characteristic features such as cell shrinkages, plasma membrane blebbing, chromatin condensation, and nuclear fragmentation. The cells treated with 3-HK showed an increase in the concentration of reactive oxygen species (ROS) as well as in caspase activity. In addition, both are involved in the 3-HK-induced apoptosis. Magnolol attenuated the cell viability reduction by 3-HK in both a dose- and time-dependent manner. Optical microscopy showed that magnolol inhibited the cell morphological features in the 3-HK-treated cells. Furthermore, the increase in the ROS concentration and the caspase activities by 3-HK were also attenuated by magnolol. These results showed that magnolol has a protective effect on the 3-HK induced cell death by inhibiting ROS production and caspase activity.

Recently, it is demanded to study about landscape. Landscape is an environment factor for improving life, a social resource for establishing image and identity of the area and also a tourist resource for earning profit. With this importance, landscape planning is being performed by local governments. However, classification for a rule about landscape planning is not prepared yet. For this purpose, classification of landscape is definitely required. Therefore, this article focuses on presenting method of classification Natural and Rural Landscape. We used Arcview 3.2 to draw watershed of the site, and calculated the percent of landform. We also took a picture which explain the landscape and made a survey of classifying the landscape. Due to this study, we were able to frame an algorithm of the landscape classification. This will contribute to classify the landscape type. This study needs more specific researches because it was supposed to target the entire Gyeonggi-Do however it only covered several regions. Through this results, it would be expected to develop the map of landscape character.

Current environmental problems of rural area are connected to loss of rural functions which is food security as well as conservation of environment, balanced development of country and succession of traditional culture. To solve these problems, recent projects are focusing on social changes in rural area and conservation of rurality creating values of rural amenity resources. At this point, full implications of rurality which is the various aspects of rurality should be defined to be applied in direct plans to conserve the rurality. In this study, nine attributes of rurality are found as various meanings with adjectives included in image of rurality. For practical use of these adjectives of rurality attributes, we evaluate the list of rural amenity resources and suggested plans for conservation of rural amenity. These attributes can be used as an effective method for village plan which brings one of the attributes into relief.
