The first successful case of a CM application in Shanghai, China in 1993 presented its possibility. According to the State Council's 'Investment system reformation', in 2004, more than 40 sub-provincial divisions in China were increased the productivity of construction by the CM application. It is predicted that CM will be utilized as a technical management method at government's plan, which raises the urbanization level more than 60% through the construction industry by 2020. However, compared with increasing CM demands, there are no complete evaluation criteria of CM in china. For instance, 26 areas in china arrange criteria individually, so. Therefore, it is necessary to establish integrated evaluation criteria on the basis of regional ones. This research will draw the evaluation criteria of selecting for the China CM Corporation in order to vitalize CM system.

During the last ten years, there have been many studies related with settlement and reinvigoration of CM. These researches have shown that the application of CM has been not reinvigorated in Korean construction industry yet, because of some problems such as the insufficient application of the public sector, the policy matters and the CM fee estimates. But the present condition data of the Korean CM Market shown in these studies was insufficient for the standpoint of Market itself. Also, some of these studies compared the Korean CM Market with The America CM Market, to study the foreign CM markets. However, because the Korea CM Market only has the CM for Fee Market but the American CM Market has the CM for Fee and the CM at Risk, the Korea CM Market must be not only compared with the America CM Market but also compared with the America CM for Fee Market. Therefore, the purpose of this study is to determine the present condition of the Korea CM Market through the compare and contrast of the Korean CM Market, American CM Market and American CM for Fee Market, by the Market Growth rate and Market Share. This study further aims to verify whether Korean CM market was implemented.

Timely application and the choice of herbicides are crucial for red pepper production since the yield is significantly reduced by weed occurrence. Experiments were conducted to provide efficient weed control methods in red-pepper fields. The results suggest the followings: 1) in the field of prevalent grass weeds, application of pendimethalin EC as pre-emergence herbicide after transplanting followed by tank-mix with pendimethalin and fluazipfop-P-butyl EC as post-emergence at 3-5 leaf stage of Digitalia species gave a good control for 80 days without crop injury, 2) as for grass and other weeds occurrence, sequential application of tank-mix with glufosinate-ammonium SL and pendimethalin at 30 days after transplanting (DAT) followed by glufosinate-ammonium. at < 20 cm of weed height with 30 days' interval provided better weed control than 2-time application of glufosinate-ammonium. single application for 80 days in this trial. 3) To prevent from drifting of non-selective herbicide spray mist into red-pepper at furrow application, glufosinate-ammonium. should be applied at 15 cm of spray nozzle height at 20 DAT (18 cm tall of red pepper), and the spray nozzle should be placed below 30 cm above ground to keep spray drift minimum to red pepper with > 40 cm plant height at 40 DAT.

Nitrate contamination in the aquatic systems is the primary indicator of poor agricultural management. The influence of sewage sludge application rates (0, 10, 25, 50 and 100 dry Mg/ha) on distribution of nitrate originating from the sewage sludge in soil profiles was investigated. Soil profile monitoring of nitrate was carried out with a Lakeland clay soil in 1997. Irrespectively of the sewage sludge application rates up to 50 dry Mg/ha, the concentration of $NO_3$-N at the 120 cm depth was below 10 mg/kg and the difference due to the amount of sewage sludge application was negligible at this depth. There was virtually no $NO_3$-N below 120 cm depth and this was confirmed by a deep sampling up to 300 cm depth. Most of the nitrate remained in the surface 60 cm of the soil. Below 120 cm depth nitrate concentration was very low because of the denitrification even at high sewage sludge rate of 100 dry Mg/ha. The $NO_3$-N concentrations in the soil fluctuated over the growing season due to plant uptake and denitrification. The risk of groundwater contamination by nitrate from sewage sludge application up to high rate of 100 dry Mg/ha was very low in a wheat grown clay soil with high water table ( < 3 m).

Construction management system has been needed to be anchored and revitalize in these days, since it was entered into a domestic market. We could consider application of CM services as a challenge of construction project system and a way to get to an advanced nation in construction field. Application of CM services could be possible in public projects by a regime. However, in case of private construction projects, it is hard to apply it without understanding of substantial necessity and propriety. so in this study, we find a application method of CM services to private small-midium construction projects, and make CM services item table of CM services for revitalization by examining the cases that applied to in private small-medium construction projects.

An experiment was carried out to investigate the effects of plant growth regulators on the growth and fiber yield of ramie. Gibberellin (GA) and Atonic acid were applied at the various levels of application dates, application frequencies and concentration. Stem growth of ramie increased greatly by applying GA on the meristem of shoot apex. Among three treatments of application frequencies of GA, that is, one time application at the stage of stem length with 50cm, twice applications at the stem length of 50cm and 100cm, and three times applications at stem length of 50cm, 100cm and 150cm, stem growth increased more as application frequency increased. GA application is more effective on stem growth at the later stage of growth than the earlier growth stage. GA treatment of 100 to 300 ppm is more effective on stem elongation than 50 ppm, which was due on the elongation of internodes without increase in number of nodes. One time application of GA enhanced leaf growth more or less regardless of concentration, but GA was applied more frequently, leaf growth was inhibited more at higher concentration. Fiber yield was the highest at the treatment of three times application of GA with 100 ppm. This treatment also showed the highest percentage of fiber with 5.3%, which is much higher value compared with that of control treatment with 4.6%. Atonic acid was less effective on stem elongation than GA, but it also seemed to be effective on the enhancement of fiber development.

Since the Construction Management(CM) was introduced into the Korea construction industry, the efforts for acceleration of CM adaption have been continued. The fact that an owner organization has the essential key to successful application of CM delivery method is true, but there has been no study on owner's organization. An owner should decide their organization type and measure their current needs of each CM business functions for successful application of CM. After the needs of CM business functions are measured, the owner should reinforce their required business functions through strengthening their in-house capability or outsourcing. Thus, this paper defines four kinds of owner organization type and suggest the form for evaluation of owner's CM ability and analyze about needs of each type's CM ability through making up question.

Fodder rye(cv. Coolgrazer) was cultivated on paddy soils under different application rates of animal manures (CM=cow manures mixed with sawdust, SM=swine manure mixed with sawdust) during 1994-1995. Rice crop (CV. Geumo) was transplanted in the same plots after fodder rye. The effects of cattle manure application on the yield performance of rye and their influence to growth, yields and quality of rice were evaluated. Fodder rye produced larger plant growth and higher silage yield in the cattle manure application than in the chemical feltilizer (CF). Dry matter yields of rye silage were 3.08 ton(CF), 4.23 ton(CM) and 6.03 ton/ha(SM), respedively. Under heavy application of cattle manures plant height, number of tillers and grains per panicle were increased, but 1,000 grains weight and total yields of rice were decreased. Yields of brown rice were 5.20 ton(CF), 5.15 ton (CM) and 4.95 ton/ha(SM), respectively. Higher concentration of amylose was found in the heavy application of cattle manures. Amylose contents of rice were 16.8%(CF), 19.1%(CM) and 19.4%(SM).

In order to find out the effect of five kinds of cultural treatments in fall crop production of potatoes the experiments were carried out with Simabara cultivar at Chonan in 1976. Sprouting of dormant seed pieces were induced by soaking in 2ppm GA and 250ppm Ethrel mixed solution for 60 minutes. Seed pieces with longer sprouts at transplanting, and increasing of urea(nitrogen) application from 10 to 30 Kg per 10a resulted better growth, yields, and quality. Application of total nitrogen at one time on 24th July(transplanting date) resulted lower emergence, yields, growth, and quality as compared with divided application on 24th July and 15th August and 5th September. Higher transplanting than 60$\times$20cm or 70$\times$17cm resulted slender growth and lower yields. Deeper mulch with wheat straw (from 4 to 12cm) induced lower maximal earth temperature in summer and higher minimal earth temperature in autumn.
