This study is presented the improvement techniques of artificial wetland, one of micro-ecosystem developed to promote bio-diversity in urban areas, through studies of problem in cases. To this end, based on instances found in broad and importance which is development method of ecological park, wetland and micro-ecosystem at cases was proved the effect of techniques. There was no monitoring result and biological lacking about biological form in urban areas in korea. But this study selected the subject which it built up until the present time and it was presumes development possibility site. So this study showed techniques to promote bio-diversity. Key result of this study are as follows. (1) There is the problem of the living environment for creatures. The artificial embankment is necessary to various water depths and considering of the living of aquatic life. It is an important factor for the ability of activity place and prevention of soil erosion for activities of aquatic insects and young fish as well as the growth of aquatic plants. Therefore, as create of the embankment must considering that form of embankment, various grade, soil stability, food-plant and as well as the plant by water to clean . (2) It is necessary for making observation way to protection. Recently, this problem must consider because of ecological park stand out in bold relief. As a result, the ecological park must accept many people to use. Therefore, nature get damaged. Until now, cases are developed deck and way for observation too accessible. So a soil environment has been change for the worse and caused soil compaction. It was menaced the living environment for creature. Therefore, suitable pattern of observation way and areas for protection through the control should be consider to protect of living environment for creatures. (3) Cases presented is lack model of living environment for creature. In such a case of a forward nation, there is studying about ecological model to promote bio-diversity even detailed part. To example, stone-constructed, to placement a log, to built of a grass-roofed house(a small cottage), it is induce a micro-living thing by create porous environment. Therefore, we must continually study for allurement a living thing at the place-constructed in urban areas. (4) Environment education program's development are more earnest are urgent. It is most important works. Therefore, study have to going afterward. The present state of artificial wetland and eco-pond were not development of program. So it is raise the problem. Environment education by placement of guide map or book and a volunteer in the field is a practice way of a narrow means. Also development program is urgent to aware important of environment and development program and training for environmental specialist have to preceding. As a result of development method groping should be sponsored education of special and efficacious.

Food security, especially in developing countries, has been threatened by several factors. Fluctuations of food production world wide and its price are caused by unstable weather condition. Even when enough is produced, control over food-producing resources and distribution causes hunger. Population growth and limitted food production could lead to widespread famines. North Korean food shortage around 300million MT a year threatens the food security of the nation as well as that of South Korea. Several alternatives were suggested such as (1) development of high yielding technologies, (2) redistribution of control over food-producing resources in North Korea and (3) enhancement of cultivated land use in winter, etc.

In this study, records of 33 cows from 20 farms were studied for herd size, feeding career, breeding record, milk yield by parity, days of dry period, days at 1st AI, number of AIs per conception, birth interval, reproductive disorder, and retention of afterbirth. And also vitamine E and selenium contents for 3 to 9 weeks after calving to find relationships with primipara age, age, dry period, days at 1st calving, hours of afterbirth, days of vaginal discharge. This study was conducted to examine the association of reproductive characteristics of dairy cows with improvement of production performance. The results were as follows; 1. For the effect of herd size on reproductive performance, farms with more than 16 multiparous cows showed 2.6 days, 23.6 days, and 23.5 days shorter for dry period, days open, and birth interval respectively. And also, reproductive disorder was 3.4% lower than other farm sizes. For the effect of feeding career, farms with over 12 years of feeding career, dry period, days open, and birth interval were 2.1 days, 14.3 days, and 14.4 days shorter, respectively, and number of AIs per conception and reproductive disorder were reduced by 0.4 and 0.8%, respectively. 2. The herds with reproductive records keeping showed 21.9 days and 22.0 days shorter for days open and birth interval, respectively, than those without reproductive records keeping. And also, number of AIs per conception and reproductive disorder were reduced by 0.5 and 3.7% respectively. For the farms with annual milk production over 6,100㎏, dry period, days open, birth interval, and days at 1st AI were 3.7 days, 17.4 days, 17.3 days, and 0.7 day, respectively shorter than those with annual milk production less than 6,100㎏. The number of AIs per conception, reproductive disorder, and retention of afterbirth were also reduced by 0.1, 3.3%, and 3.4%, respectively. 3. For the herds with the level of vitamin E less than 7.0㎍/㎖ in blood serum 3 weeks after calving, dry period and retention of afterbirth were reduced by 4.5 days and 2.9%, respectively. For the farms with the level of vitamin E greater than 7.0㎍/㎖ in blood serum 3 weeks after calving, reproductive disorder and retention of afterbirth were reduced by 7.9% and 1.4%, respectively. 4. For the herds with primipara age less than 24 months, dry period and number of AIs per conception were reduced by 3.8 days and 0.2 respectively. In 3 to 9 weeks after calving, blood serum content was 4.8ng/㎖ more and hours of afterbirth and days of vaginal discharge was reduced by 0.5 hr and 1.9 day, respectively. 5. For the herds with cows age less than 48 month, days open and birth interval were 14.5 days and 23.6 days longer, respectively. The vitamin E content in blood serum was 0.9㎍/㎖ less but selenium content was 4.2ng/㎖ higher. The hours of afterbirth and days of vaginal discharge were reduced by 1.2 hr and 0.8 day. 6. For the herds with the level of vitamin E less than 7.0㎍/㎖ in blood serum 9 weeks after calving, dry period, days open, birth interval, and days of vaginal discharge were reduced by 8.4 days35.9 days, 45.6 days, and 3.6 days, respectively. However, for the herds with selenium content greater than 90ng/㎖, dry period, number of AIs per conception, hours of afterbirth, and days of vaginal discharge were reduced by 3.3 days, 0.3, 0.5 hr, and 1.8 day, respectively. 7. The vitamin E content in blood serum was 6.3 ㎍/㎖ in 2 weeks after calving and increased to 12.3㎍/㎖ in 6 weeks after calving. The selenium content was 38.2ng/㎖ in 2 weeks after calving and showed 62.3 to 66.7ng/㎖ in 7 to 9 weeks after calving.

This research was undertaken in order to obtain the technological skill and good information on the feeding and raising of ostrich in Korea. Ostrich meat have been confirmed with edible meat in Korea since May, 2000. Ostrich meat contains reddish color, which is low calorie, high protein, and low fat. Most of people preferred to high protein meat contained plenty of nutrients except high fat including high cholesterol. We could utilize as edible and palatable foods such as pure meat, large egg, bone including bone extraction, and fur. Therefore, this animals could be called as an economical poultry. Ostrich husbandry, in the future, should be maintained with environmental agriculture. Without our desirable environment, we as well as animals also could eventually be destruction. The characteristics of raising ostrich as well as duck is the use of remains of extra food as a recycling. Especially, ostrich eats very well voraciously everything to be edible. Especially, ostrich, in poultry, grows very well in early stage in course of growth. On the other hand, it is difficult for most of farmer to market and to improve the strategy of high qualities of meat. Accordingly, many farmers who are raising ostrich try to improve and to enhance feeding skill as well as reproductive and genetic breeding. And then, we should establish logical and systematical marketing strategy through good management including improvement of meat.
