The study was aimed to assess the expected impact of climate change on the water cycle and soil losses in Daecheong Reservoir watershed, Korea using the Soil and Water Assessment Tool (SWAT) that was validated for the watershed in a previous study. Future climate data including precipitation, temperature and humidity generated by introducing a regional climate model (Mesoscale Model Version 5, MM5) to dynamically downscale global circulation model (European Centre Hamburg Model Version 4, ECHAM4) were used to simulate the hydrological responses and soil erosion processes in the future 100 years (2001~2100) under the Special Report on Emissions Scenario (SRES) A1B. The results indicated that the climate change may increase in the amount of surface runoff and thereby sediment load to the reservoir. Spatially, the impact was relatively more significant in the subbasin Bocheongcheon because of its lower occupation rate of forest land compared to other subbasins. Seasonally, the increase of surface runoff and soil losses was more significant during late summer and fall season when both flood control and turbidity flow control are necessary for the reservoir and downstream. The occurrence of extreme turbidity flow events during these period is more vulnerable to reservoir operation because the suspended solids that remained water column can be resuspended by vertical mixing during winter turnover period. The study results provide useful information for the development of adaptive management strategy for the reservoir to cope with the expected impact of future climate change.

In an agent-based system, each agent has its own decision making capability and competes, cooperates, and communicates each other with an agent interface. Virtual manufacturing has characteristics as a typical application area of agent-based system: complex and time-bound decision making and negotiation. The time-boundness influences the choice of decision making models and design of protocols for internal and external negotiation. In this paper, we provide a case study which suggests a time-bound framework for external and internal negotiation between the agents for virtual manufacturing environment. We illustrate decision making model selection strategy and the system architecture of the agent-based system for the complex and time-bound environment.

To survive competitive global market, textile and fashion business incorporated Supply Chain Management strategy to make product and information flows fast and correct. Especially textile and fashion industry involves many complicated channels from up stream, middle stream, to down stream for delivering their production. Evaluating SCM performance is very critical to make better business profit model. Representative Scor model and BSC method are well fitted into textile and fashion business because of distributional complexity, non-financial factors to be considered, and innovative product characteristics. But there was little study to compare these two methods for textile and fashion business. Therefore, the purpose of this study was to investigate the Scor model and BSC method based upon review of literatures. The results of this study were as follows: Scor model had some strengths which were availability to apply for various industries due to standardized process, operation process emphasized, various customizable factors to compose for the company, and premise on SCM strategic execution. BSC method had some strengths which were the balance including financial and non-financial factors, qualitative analysis, and considering the goal and vision to convey organically from top to bottom of organization. The main differences between them were different scope to deal with performance estimating index from qualitative to quantitative analysis, the scope of human resources to manage, and possibility of performance comparison among companies.

The purpose of this study was to examine the effects of a lifestyle consisting of a health oriented diet and personal motivation toward health improvement on an individual's desire to participate in condolence or "healing" -workshops and programs. In order to examine the influence of the "health diet" and motivation, the "health diet" lifestyle was classified into nutrition pursuit factors, psychological factors, food safety factors, and health conscious consumption factors. Personal motivation was categorized into perceived benefits, environmental factors and the individual's desire for happiness. Empirical analysis showed that nutrition pursuit factors had an impact on perceived benefits and the desire for happiness. Psychological aspect factors had a significant influence on perceived benefits, environmental factors and the desire for happiness. However, food safety factors and health conscious consumption factors did not have an effect on individual motivation to improve health. Regarding personal motivation toward health improvement on the desire for "healing", perceived benefits and environmental factors had significant influence. However, the individual's desire for happiness did not influence the demand for "healing". Regarding the effect of a "health diet" on the desire for "healing", only the psychological aspects of a "health diet" had any significant effects on the desire for "healing". The results from this study can help local organizations or service companies that provide "healing" programs with developing effective marketing strategies that could lead to greater customer satisfaction. Especially, the significant influence of psychological aspects of a "health diet" on the demand for "healing" is noteworthy in that this could play a key role in establishing a more effective marketing strategy to attract increasing numbers of consumers using health conscious diets.

The use of novel isolates of Trichoderma with efficient antagonistic capacity against Fusarium oxysporum f. sp. lycopersici (FOL) is a promising alternative strategy to pesticides for tomato wilt management. We evaluated the antagonistic activity of 30 isolates of T. asperellum against 4 different isolates of FOL. The production of extracellular cell wall degrading enzymes of the antagonistic isolates was also measured. The random amplified polymorphic DNA (RAPD) method was applied to assess the genetic variability among the T. asperellum isolates. All of the T. asperellum isolates significantly reduced the mycelial growth of FOL isolates but the amount of growth reduction varied significantly as well. There was a correlation between the antagonistic capacity of T. asperellum isolates towards FOL and their lytic enzyme production. Isolates showing high levels of chitinase and ${\beta}$-1,3-glucanase activities strongly inhibited the growth of FOL isolates. RAPD analysis showed a high level of genetic variation among T. asperellum isolates. The UPGMA dendrogram revealed that T. asperellum isolates could not be grouped by their antagonistic behavior or lytic enzymes production. Six isolates of T. asperellum were highly antagonistic towards FOL and potentially could be used in commercial agriculture to control tomato wilt. Our results are consistent with the conclusion that understanding the genetic variation within Trichoderma isolates and their biochemical capabilities are required for the selection of effective indigenous fungal strains for the use as biocontrol agents.

Thermo-hydro-chemico-mechanical evolution of the radioactive waste repository and surrounding geological media is one of the key issues for the radioactive waste disposal. This article describes not only the basic context for the site selection but also a reasonable strategy for the repository related research based on the results of the French repository project carried out by ANDRA (National radioactive waste management agency). To have some alternatives for the determination of a preferable depth and geological media, it would be recommendable to establish a database system. The curing process of the fractures or microfissures in the EDZ (Excavation Disturbed Zone) during operation time has to be examined considering the evolution of the EDZ and the reversibility of the repository. It is prerequisite to carry out a feasibility study and to validate the design concept and design parameters in a properly constructed underground research laboratory (URL) in Korea.

In recent years, the number of walking-tourists who visit Jeju olle trail are increasing every year and the ripple effect is a rapid change on the roles and leadership of local people in rural villages. The reason for the change is that most Jeju Olle Trails cuts through the rural village in Jeju island. However, most of travelers just walked along the trails, no one was interested about villages along the Olle roads. For these reasons, many rural villages would not get any benefits such as non-farm income, sales profit and also can not activate the facility of village and infrastructure. Therefore, we study on Revitalization Method for rural villages through the Analysis of characteristics of tourist in Jeju Olle Trails and a field survey research too. In this process, we investigated the status and characteristics of the rural villages of Jeju island in the first step. Then, we considered the distinct characteristics and factors for improving of the 10 places with site investigation where were recommended by Jeju Olle Corporation and Jeju Agricultural Technology Center in second step. Lastly, we arranged the resident's requirement and result of survey and interview with leaders of rural village. As a result, we suggest the activation methods for residents and leaders of rural area and this study is also expected to help management of rural villages and also is an important study to improve importance of utilizing of more people visiting in Jeju Olle Trails.
