The study was conducted to determine effects on forage productivity, feed value, grazing intensity and livestock productivity in growing Korean native female goat grazing in native pasture. Its with average initial body weight of 14.10±3.6kg and an average age of 4 months were used in this study. Dry matter content of native pasture was the highest at 33.48 ± 2.56% in June, and the content was significantly increased from spring to autumn (p<0.05). Crude protein was maintained between 11% and 12% on average. Nutrient content was maintained at a certain level in native pasture, but there were differences due to the different types of wild grasses produced in each season. The productivity of forage crops increased from June, but decreased after August and showed a characteristic of grassland where productivity decreased rapidly in spring and autumn. The average grazing intensity are 39 head/ha. Black goat average daily gain was 80.2g/d. The stable weight gain in grazing is that the nutrient requirement of the black goat was met by supplementing the concentrated feed during grazing. study, can be expected that the productivity of livestock can be increased through the proper feeding of supplementary feed and maintenance of grazing intensity

11 종의 목이버섯 자실체로부터 얻은 50% EtOH추출물을 사용하여 지방전구세포인 3T3-L1의 지방세포 분화억제 효과를 확인한 모든 strain에서 억제효과가 존재하였다. 털목이에서는 21001 균주가 가장 우수하였고 흑목이에서는 21002 균주가 억제효과가 우수하였다. 전반적으로 털목이가 흑목이에 비해 지방세포 분화억제 효과가 우수하였다. 또한 Adipocyte RNA 발현량과 protein 발현량 측정 실험에서도 털목이 21001 균주가 지방세포 분화억제효과에 있어서 가장 우수하였다. 털목이 21001 버섯을 사용하여 동물실험을 진행한 결과 털목이 자실체 분말이나 50% EtOH 추출물을 급여한 실험에서 체중 감소효과가 나타났으며, 특히 EtOH 추출물 0.2%를 급여한 군에서 유의하게 감소함을 확인하였다(*P<0.05). 동물 희생 후 적출한 간 중량 및 부고환지방량과 혈청 내 중성지방 및 총 콜레스테롤, 혈당, ALT, AST 등도 털목이버섯 21001 EtOH 추출물 0.1% 이상 급여 시 고지방식이만을 급여한 군에 비해 유의차(*P<0.05 이상) 있게 감소함을 확인하였다.

잎새버섯을 병재배 새로운 소득 품목으로 개발하고자 적정 발이방법을 구명하기 위한 연구결과는 다음과 같다. 발이는 모든 처리구에서 6일째 개시가 되었으나, T7(균긁기후 역상)은 9일로 다른 처리보다 3일 늦었다. 발이율은 T3(페트리디쉬)과 T7이 98.9%로 가장 높고, 전체 재배기간은 T7이 51일로 다른 처리구의 46~47일보다 3일 늦은 것으로 나타났다. 수량성은 T3과 T7이 각각 110g과 112g으로 우수하였으나, T7의 방법이 자실체의 발생도 균일하고, 품질도 우수하여(장단비 0.89) 잎새버섯 병재배에 적합한 발이방법으로 판단되었다.

Unlike other types of outdoor advertisements, rooftop signboards are installed on the roofs of buildings, rather than on their outer walls. This means that the area of a rooftop signboard is commonly larger than that of a general outdoor signboard. Moreover, as such signboards are greatly influenced by the wind, they can suffer a lot of damage from typhoons and strong winds every year. However, there is no wind load specification for rooftop signboards. In this study, wind pressure experiments were conducted to investigate the peak wind pressure on each side of rooftop signboards installed on the roofs of 5–15 story buildings in a city center. The minimum peak wind pressure coefficient was –3.0 at the bottom edges of the front and back of the rooftop signboards and –2.0 along the entire length of the sides . As the height of the rooftop signboard increased with the increasing height of the buildings, the peak value was found to be larger than the absolute peak value for the minimum peak wind pressure coefficient. The maximum and minimum peak wind pressure distributions of the rooftop outdoor signboards were influenced by the position of the signboard and the wind angle.

Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.
