The purpose of this study is to improve the National Fire Mobilization Plan. This plan is a national-level comprehensive response system aimed to compensate for scarce firefighting resources and minimize damage from large-scale disasters that exceed the response limits of city and province firefighting forces. As such, relevant literature and domestic and foreign firefighting mobilization standards were reviewed, and simulations of firefighting mobilization were performed using the QGIS program to compare and analyze cases. Results showed that, as opposed to the current method of issuing mobilization orders by dividing resources according to city and province, recognizing the entire country as a single entity and prioritizing the mobilization of adjacent firefighting resources is more effective in terms of minimizing time and distance and more quickly securing resources. Regarding national firefighting mobilization, recognizing the country's firefighting resources as a whole will allow adjacent firefighting resources to be mobilized with priority. However, the mobilization-related limits of each region need to be set to respond to local disasters. Once the scale of mobilization is determined, a system that can quickly calculate how to mobilize firefighting resources based on location and distance can be established. Additionally, it is necessary to create an integrated management system so the central government can directly organize and mobilize local firefighting resources.

In reality, it is a green revolution of the entire agricultural matrix in Korea that integrated pest control plays an important role in the possible breakthrough in rice self-sufficiency. In paddy agroecosystem as man-modified environment, rice is newly established every year by transplantation under diverse water regimes which affect a microclimate. Standing water benefits rice by regulating the microclimate, but it favors the multiplication of certain pets through the amelioration of the microclimate. Further, the introduction of high yielding varieties with the changing of cultural practices results in changing occurrence pattern of certain pests. In general, japonica type varieties lack genes resistant to most of the important pests and insect-borne virus diseases, whereas indica type possesses more genes conferring varietal resistance. Thus, this differences among indica type, form the background of different approaches to pest management. The changes in rice cultivation such as double cropping, growing high-yielding varieties requiring heavy fertilization, earlier transplanting, intensvie-spacing transplanting, and intensive pesticide use as a consequence of the adoption of improves rice production technology, have intensified the pest problems rather than reduced them. The cultivation of resistant varieties are highly effective to the pest, their long term stability is threathened because of the development of new biotypes which can detroy these varieties. So far, three biotypes of N. lugens are reported in Korea. Since each resistant variety is expected to maintain several years the sequential release of another new variety with a different gene at intervals is practised as a gene rotation program. Another approach, breeding multilines that have more than two genes for resistance in a variety are successfully demonstrated. The average annual rice losses during the last 15 years of 1977-’91 are 9.3% due to insect pests without chemical control undertaken, wehreas there is a average 2.4% despite farmers’insecticide application at the same period. In other words, the average annual losses are prvented by 6.9% when chemical control is properly employed. However, the continuous use of a same group of insecticides is followed by the development of pest resistance. Resistant development of C. suppressalis, L. striatellus and N. cincticeps is observed to organophosphorous insecticides by the mid-1960s, and to carbamates by the early 1970s in various parts of the country. Thus, it is apparent that a scheduled chemical control for rice production systems becomes uneconomical and that a reduction in energy input without impairing the rice yield, is necessarily improved through the implementation of integrated pest management systems. Nationwide pest forecasting system conducted by the government organization is a unique network of investigation for purpose of making pest control timely in terms of economic thresholds. A wise plant protection is expected to establish pest management systems in appropriate integration of resistant varieties, biological agents, cultural practices and other measures in harmony with minimizing use of chemical applications as a last weapon relying on economic thresholds.

This study analyzed the outcomes of the Healthy Family Support Center's 2011 Pilot Project to support grandparent-grandchild families. This paper applied Frank Fisher's multidimensional evaluation methodology, which includes 4 steps: program verification, situational validation, system vindication and social choice. The major findings and their implications are as follows: the strong points of the pilot project are the characteristics of its services, i.e. sending services, customized services, family-unit services and integrated services. Therefore, it is necessary to train human resources to deliver these services more professionally and to provide comprehensive life-planning. The weak point of the pilot project is its lack of services relating to the self-reliance of the clients. Thus it is necessary to revise the service subsystems to include programs that promote self-support measures.

In proton exchange membrane fuel cell (PEMFC), proper thermal management of the stack and moisture generation by electrochemical reactions significantly affect fuel cell performance. In this study, the PEMFC dynamic characteristic model was developed through Simcenter AMESim, a development program. In addition, the developed model aims to understand the thermal resin balance of the stack and performance characteristics for input loads. The developed model applies the thermal management model of the stack and the moisture content and permeability model to simulate voltage loss and stack thermal behavior precisely. This study extended the C based AMESet (adaptive modeling environment submodeling tool) to simulate electrochemical reactions inside the stack. Fuel cell model of AMESet was liberalized with AMESim and then integrated with the balance of plant (BOP) model and analyzed. And It is intended to be used in component design through BOP analysis. The resistance loss of the stack and thermal behavior characteristics were predicted, and the impact of stack performance and efficiency was evaluated.

우리나라에서 제초제 저항성작물의 개발과 저항성작물의 실용화 재배가 이루어질 경우를 대비하기 위하여 제초제 저항성작물 개발 및 잡초방제 연구현황을 분석하고 앞으로의 잡초방제 방향과 전망에 관하여 기술하였다. 제초제 저항성작물 개발은 작물에 대한 약해 없이 한 가지 제초제만을 사용해서 선택적으로 광범한 잡초방제 효과를 나타낼 수 있는 획기적인 잡초관리 기술의 하나이다. Glyphosate 저항성 형질전환 콩, 옥수수, 캐놀라, 면화에서 glyphosate 사용은 단순한 잡초방제법으로 저비용으로 편리하게 잡초를 관리할 수 있다. 한 작물에 glyphosate와 glufosinate에 모두 저항성인 이중저항성작물은 옥수수, 콩, 면화에서 개발되어 glyphosate 저항성잡초를 방제할 수 있었으며, 기존 제초제 기술의 영역을 확장할 수 있을 것이다. 그리고 glyphosate를 ALS 저해형 제초제, 합성옥신 제초제, HPPD 저해형 제초제 혹은 ACCase 저해형 제초제를 포함한 새로운 제초제 저항성작물 개발은 제초제 저항성잡초를 효과적으로 방제하기 위하여 가까운 장래에 개발되기를 기대한다. 또한 제초제 저항성작물만으로는 잡초문제를 해결할 수 없기 때문에 앞으로 다른 작용기작 제초제의 교호사용, 기계적, 경종적 방법을 통합한 종합적잡초관리 체계에 관한 연구가 요망된다.
