The objective of this experiment was to determine agronomic characteristics, and forge yield and quality responses of rye variety to location and year for a double-cropping system in South Korea. Five forage rye varieties ('Koolgrazer', 'Jlee select', '9909', 'Homill22', 'Danko') were evaluated for forage quality and yields during the two growing years (the First year; 2001-2002, and the Second year; 2002-2003) at two locations (the central and southern zone). The heading date of rye in the central zone (Cheonan) was 15 April, and that of the southern zone (Daegu) was 10 April. The heading dates of 'Koolgrazer', 'Jlee select' and '9909' were earlier than those of the others. Although the five varieties had resistance to foliar diseases and insects, these had less lodging resistance. Dry matter (DM) content, DM and total digestible nutrients (TDN) yields had significant differences among rye varieties. DM and TDN yields of the rye varieties at the second year were higher than the first year in the central zone. In the southern zone, DM and TDN yields at the first year were lower than the second year. 'Jlee select' and '9909' had higher DM and TDN yields than the other varieties in both location and year except the first year of the central zone (p<0.001). The crude protein (CP) contents of rye grown in Cheonan were higher than Daegu. The CP content of 'Danko' variety was highest among tested varieties. The acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents were greater for the varieties grown in Cheonan and in the second year. The ADF and NDF contents of 'Danko' were lowest, while 'Danko' in TDN and relative feed value (RFV) was highest among rye varieties. Our study showed that there are differences in forage production and quality from location to location, year to year and variety to variety. Therefore, forage quality and forage production are an important factor for screening forage rye varieties. Early maturing varieties should be recommended as high-yielding forage in a double-cropping system because their production of forage was greatest early in the season.

Construction Management(CM) and Building Information Management(BIM) have a lot in common that they need to establish a cooperation system among different disciplines and promote smooth communication among project stakeholders throughout the project life-cycle. BIM can be an effective information management tool for CM's business and improve their service value. However, BIM uses by Construction Managers(CMr) are very limited. The objective of this study is to analyze the intention of CMrs to adopt BIM and establish effective BIM use strategy in the CMr's point of view. This study utilizes Technology Acceptance Model(TAM) as a research method, and the results show that 1) CMrs think it is more important whether BIM is required to be adopted in their business process at the social or industry level than that BIM can improve their personal competence, recognition, and impressions through their voluntary BIM adoption; 2) that CMrs think it is important to figure out business processes where BIM can be smoothly incorporated; and 3) that CMrs hesitate the use and trial of BIM in their realworld business although they agree that BIM needs to be eventually adopted in their business in the future. Based on these results, directions for establish a strategy for BIM adoption were proposed at the CMr's point of view

In spite of bulk literature about the tuning of TMD, the effectiveness of TMD in reducing the seismic response of engineering structures is still in a row. This paper deals with the optimum tuning parameters of a passive TMD and simulated on MATLAB with a ten-story numerical shear building. A weighted multi-objective optimization method based on computer experiment consisting of coupled with central composite design(CCD) central composite design and response surface methodology(RSM) was applied to find out the optimum tuning parameters of TMD. After the optimization, the so-conceived TMD turns out to be optimal with respect to the specific seismic event, hence allowing for an optimum reduction in seismic response. The method was employed on above structure by assuming first the El Centro seismic input as a sort of benchmark excitation, and then additional recent strong-motion earthquakes. It is found that the RSM based weighted multi-objective optimized damper improves frequency responses and root mean square displacements of the structure without TMD by 31.6% and 82.3% under El Centro earthquake, respectively, and has an equal or higher performance than the conventionally designed dampers with respect to frequency responses and root mean square displacements and when applied to earthquakes.

In South Korea, 850 standard watersheds and 7,807 KRF catchment areas have been used as basic maps for water resources policy establishment, however it becomes necessary to set up new standard maps with a more appropriate scale for the integrated managements of surface water-groundwater as well as water quantity-quality in the era of integrated water management. Since groundwater has a slow flow velocity and also has 3-D flow properties compared to surface water, the sub-catchment size is more effective than the regional watershed for the evaluation of surface water-groundwater interaction. The KRF catchment area, which has averagely a smaller area than the standard watershed, is similar to the sub-catchment area that generally includes the first-order or second-order tributaries. Some KRF catchment areas, which are based on the surface reach, are too small or large in a wide plain or high mountain area. Therefore, it is necessary to revise the existing KRF area if being used as a unit area for integrated management of surface-water and groundwater. A unit watershed with a KRF area of about 5 to 15 ㎢ can be effective as a basic unit for water management of local government considering a tributary composition and the location of groundwater wells, and as well it can be used as a basic tool for water demand-supply evaluation, hydrological observation system establishment, judgment of groundwater permission through a total quantity management system, pollution assessment, and prioritizing water policy, and etc.
