This study aims to demonstrate the effect of farming technology on introducing medicinal plants (MP) and wild food plants (WFP) into a traditional agricultural system within peri-urban zones. Field investigations and semi-structured focus group interviews conducted in the Buhozi community showed that 27 health and nutrition problems dominated in the community, and could be treated with 86 domestic plant species. The selected domestic MP and WFP species were collected in the broad neighboring areas of the Buhozi site, and introduced to the experimental field of beans and maize crops in Buhozi. Among the 86 plants introduced, 37 species are confirmed as having both medicinal and nutritional properties, 47 species with medicinal, and 2 species with nutritional properties. The field is arranged in a way that living hedges made from Tithonia diversifolia provide bio-fertilizers to the plants growing along the hedges. The harvest of farming crops does not disturb the MP or WFP, and vice-versa. After harvesting the integrated plants, the community could gain about 40 times higher income, than from harvesting farming crops only. This kind of field may be used throughout the year, to provide both natural medicines and foods. It may therefore contribute to increasing small-scale crop producers' livelihood, while promoting biodiversity conservation. This model needs to be deeply documented, for further pharmaceutical and nutritional use.

After coming this century, as the propagative method of plants on a scientific foundation has been accompanied systematically, it has played an important part in the improvement of cultivar. But an existing propagative technique is not a few defects in our tasks and industrial structure which changes every hour and envirnment which undergoes a sudden change. To use developed biological knowledge recently, and existing propagative method which is main axis in sexual reproductive crossing, is increased much in the inside of internal organs by asexual reproductive means which is on a different level, and by, introducing a new character, it improves an inherited character etc. We have observed methods which supplement or replace a defect. These methods are not yet ripe for putting to practical use in the present research phase but convinced that they will offer an epoch-marking turning point.

The paper discusses the methodology and the use of probabilistic seismic hazard analysis (PSHA) for nuclear power plants from a European perspective. The increasing importance of risk-informed approaches in the nuclear oversight process observed in many countries has contributed to increasing attention to PSHA methods. Nevertheless significant differences with respect to the methodology of PSHA are observed in Europe. The paper gives an overview on actual projects and discusses the differences in the PSHA-methodology applied in different European countries. These differences are largely related to different approaches used for the treatment of uncertainties and to the use of experts. The development of a probabilistic scenario-based approach is identified as a meaningful alternative to the development of uniform hazard spectra or uniform confidence spectra.

This paper introduce Renewable Energy forecasting technology, which is a part of renewable management system. Then, calculation method of dedicated transmission line's meteorological data to forecast renewable energy is suggested. As the case of dedicated transmission line, there is only power output data combined the number of renewable plants' output that acquired from circuit breakers. So it is need to calculate meteorological data for dedicated transmission line that matched combined power output data. this paper suggests two calculation method. First method is select the plant has the largest capacity, and use it's meteorological data as line meteorological data. Second method is average with weight that given according to plants' capacity. In case study, suggested methods are applied to real data. Then use calculated data to Renewable forecasting and analyze the forecasting results.

외래식물이 새로운 환경에 성공적으로 정착할 수 있는 이유를 설명하는 주된 두 개의 가설은, 외래식물이 새로 정착할 지역 군집 구성원들과 충분히 달라 경쟁을 피할 수 있기 때문이라는 것, 그리고 이미 적응하고 있는 그 지역 군집의 구성원과 유사하여 새로운 환경에 잘 적응할 수 있기 때문이라는 것이다. 본 연구는 낙동강변에 인위적으로 조성된 습지공원지역을 대상으로 외래(귀화) 초본식물과 자생 초본식물의 기능 형질을 조사하여 상호 비교 분석하여 앞의 두 가설 중 어느 가설이 맞는지 확인하고자 하였다. 식물 잎 형질 중, 잎 면적, 잎 면적비, 잎 두께, 잎 건조 중량, 잎 질소량, 잎 탄소량을 이용하여 분석한 결과, 외래(귀화)식물과 자생식물이 서로 구분되었고, 이는 외래(귀화)식물이 자생식물보다 잎 질소량이 높기 때문인 것으로 생각되었다. 높은 잎 질소량은 높은 광합성률과 연관되고 이는 효과적인 자원 이용 및 빠른 생장과 관련있음을 고려할 때, 본 연구지역에 정착한 외래식물 역시 이러한 기능적 특징을 가지고 있는 것으로 생각되었다. 본 연구 결과는 앞의 두 가설 중 외래식물과 자생식물의 기능적 차이가 외래식물 정착 성공을 결정한다는 가설을 지지하는 것으로 보인다.

Planting intercropping in rubber plantations is another alternative for generating more income for farmers. However, farmers still lack the knowledge of choosing plants. In addition, information for decision making comes from many sources and is knowledge accumulated by the expert. Therefore, this research aims to create a decision support system for growing rubber trees for individual farmers. It aims to get the highest income and the lowest cost by using semantic web technology so that farmers can access knowledge at all times and reduce the risk of growing crops, and also support the decision supporting system (DSS) to be more intelligent. The integrated intercropping ontology and rule are a part of the decision-making process for selecting plants that is suitable for individual rubber plots. A list of suitable plants is important for decision variables in the allocation of planting areas for each type of plant for multiple purposes. This article presents designing and developing the intercropping ontology for DSS which defines a class based on the principle of intercropping in rubber plantations. It is grouped according to the characteristics and condition of the area of the farmer as a concept of the rubber plantation. It consists of the age of rubber tree, spacing between rows of rubber trees, and water sources for use in agriculture and soil group, including slope, drainage, depth of soil, etc. The use of ontology for recommended plants suitable for individual farmers makes a contribution to the knowledge management field. Besides being useful in DSS by offering options with accuracy, it also reduces the complexity of the problem by reducing decision variables and condition variables in the multi-objective optimization model of DSS.
