This paper investigate the qualities variety of concrete using recycling water under various kinds and contents of saccaric based stabilizing agent(SSA). Fluidity had little changes with the kinds and contents of SSA. Air contents of concrete with recycled water only shows the tendency. With an increase in SSA contents, air content recovered. For bleeding properties, bleeding shows to be decreased with an increase in SSA contents. The use of recycled water accelerated the setting time. However, with an increase in SSA, setting time showed the similar level of plain concrete. SSA (Btype) had better performance in enhancing compressive strength owing to loss of air content. Although the use of recycled water increased the drying shrinkage compared with that of plain concrete, it tended to decrease with an increase in SSA.

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.

To develop new varieties of rapeseed (Brassica napus L.), the seeds of three varieties, 'Naehan', 'Tammi', and 'Halla' were irradiated with proton ion beams and gamma rays with 0 to 2,000 Gy. We had selected 9 lines in $M_5$ generation, and their useful characteristics were investigated by progressing from $M_6$ to $M_7$ generation for checking uniformity and stability. The 9 lines selected in $M_5$ generation were maintained their characteristics in terms of flowering date, maturing date, and plant height through $M_6$ to $M_7$ generations. Especially, 2 lines of NP600-1-1-198-2-1 and NP1000-13-2-362-4-1 selected in $M_5$ generation derived from 'Naehan' had characteristics of early maturity and shorter stem than original variety, and they also were maintained characteristic of early maturity such as 10~11 days earlier flowering date and 6~9 days earlier maturing date through $M_6$ to $M_7$ generations. For stem length, they showed characteristics of shorter stem in 2 lines of NP600-1-1-198-2-1 line and NP1000-13-2-362-4-1 line about 16%, 25% shorter stem than original variety respectively through $M_6$ to $M_7$ generations. Furthermore, some characteristics of 2 lines compared to the original variety were similar or higher in weight of 1,000 seeds, number of branches per plant, number of siliqua per panicle, number of seeds per silique, oil contents, and oleic acid contents. The line with large and plump flowers selected in $M_5$ generation also showed large and dark yellow flowers through $M_6$ to $M_7$ generations. The lines with High oleic acid and low saturated fatty acid contents selected in $M_5$ generation were maintained characteristics through $M_6$ to $M_7$ generation and these useful characteristics were expected for developing a new variety for bio diesel uses.

Single ascospores was isolated in Yesan-gun, Chungnam in 2006 with Cordyceps militaris. This study was carried out to select the superior isolates which produce more fruiting body and contain more cordycepin contents. Five single ascospore isolates were cultured on brown rice pupae medium and they formed fruiting bodies. To select better isolates, each isolates was hybridized and then the characteristics and cordycepin contents were investigated. After biological efficiency and codycepin contents were examined, finally C0601S05 was selected. Top-cross test of isolate C0601S05 was carried with 29 single ascospores. From this test, isolate C0601S05${\times}$C0601S33 and isolate C0601S05${\times}$C0601S43 containing highest cordycepin contents were selected. Codycepin contents of C0601S05 was 246mg% and those of C0601S05${\times}$C0601S33 and C0601S05${\times}$C0601S43 were 325mg% and 280mg%, respectively. C0601S05${\times}$C0601S33 was registered as Yedang 3 at the Korea seed & variety service.

The purposes of the study is to see as to how much of changes has occurred in the newly revised Home Economics Textbooks required by the 6th Curriculum as compared to those by the former the 5th Curriculum, and to seek future policy directions which can be improved even better, if any, for further revision. To implement this proposal, the study employs 8 different textbooks published in 1997 geared for the 6th Curriculum for data base. The components of the contents divides into two major parts. The first part falls into a category of holistic analysis of the textbooks, which gives a general perspective of the changes in the textbook revised. It includes those areas of changes in the total number of pages, cover page, illustrations, table of contents, appendices, unit cover, introductory remarks, summary and evaluation, etc. It also covers the information on authors of textbook. The latter part consists of several specific areas of major changes occurred in the textbooks for the 6th Curriculum. It covers such areas of changes in the composition of category and its weight, laboratory experiences, and illustrations and tables. To conclude the study, among many findings, two major points are of great importance to mention here. First, the new textbooks have adopted more of varieties in physical appearances and contents per se as to the older ones. And yet, there still found a weakness in numbers of authors participated to a full reflection of contents variety. In addition, the background of authors reflected on an unrealistic idealism which lacks the on-site information provided by the school teachers. Second, the strict regulations created by the Ministry of Education for developing textbook found restricting the authors creativity and thus contents variety of textbooks. Those restricting factors include letter type and size, coloring, paper quality, and volume size.

Recently, with the growing use of e-learning, instructors develop new online courses using a variety of contents and then store the results on their computers. These contents should be updated with new information as time goes on, and a new content also can be produced by reusing these ones. However, a lot of time will be needed for instructors to search, edit, and manage various contents stored from place to place on their computers. Currently, the development of the e-learning content management tool. which performs efficiently these functions on the PC environment, leaves much to be desired. Therefore, in this paper, we proposed an e-learning content creation and management system which can manage efficiently a variety of contents stored from different locations on an instructor's computer and can develop easily new online courses. The proposed system can be used widely to develop contents for instructors based on the PC environment. For performance evaluation, this paper compared the proposed system with the previous system according to the retrieval time of content keyword, and the experiment showed that our system is much better than the previous one.
