This study was designed to predict the changes in species richness of plants under the climate change in South Korea. The target species were selected based on the Plants Adaptable to Climate Change in the Korean Peninsula. Altogether, 89 species including 23 native plants, 30 northern plants, and 36 southern plants. We used the Species Distribution Model to predict the potential habitat of individual species under the climate change. We applied ten single-model algorithms and the pre-evaluation weighted ensemble method. And then, species richness was derived from the results of individual species. Two representative concentration pathways (RCP 4.5 and RCP 8.5) were used to simulate the species richness of plants in 2050 and 2070. The current species richness was predicted to be high in the national parks located in the Baekdudaegan mountain range in Gangwon Province and islands of the South Sea. The future species richness was predicted to be lower in the national park and the Baekdudaegan mountain range in Gangwon Province and to be higher for southern coastal regions. The average value of the current species richness showed that the national park area was higher than the whole area of South Korea. However, predicted species richness were not the difference between the national park area and the whole area of South Korea. The difference between current and future species richness of plants could be the disappearance of a large number of native and northern plants from South Korea. The additional reason could be the expansion of potential habitat of southern plants under climate change. However, if species dispersal to a suitable habitat was not achieved, the species richness will be reduced drastically. The results were different depending on whether species were dispersed or not. This study will be useful for the conservation planning, establishment of the protected area, restoration of biological species and strategies for adaptation of climate change.

The purpose of this research is to seek political implications for management and activation of National Forest Complex Management(NFCM). Survey method was utilized for workers as respondents to measure importance and performance of NFCM. As a result, it turned out that the respondents' performance was very high. In addition, out of 14 items, two items -1) activation of e-commerce and direct business transaction, 2) production and sales marketing information, which intensive management strategy, were derived from results. Also, 6 items were derived for on-going maintenance, 3 items were derived for low priority order, and other 4 items were derived for discouragement against excessive efforts. This research may contribute to providing fundamental sources that can be utilized for promoting direction establishment and system improvement of NFCM.

The diurnal range of temperature in korea is increasing. We know that the environment has deteriorated through report about railway damage and economic loss caused by climate. In these conditions, Monitoring device for railway must operate to support the operations and maintenance. Therefore, In this paper, COM-based monitoring device implemented using Industrial-Extended electronic components and made, We tested compliance about temperature environment of actual railway. We verified through testing about cold and dry heat of monitoring device. Used components in this product will be able to utilize the development of the railway industry of electronics.

The purpose of this paper is to analyze thermal sensation which is measured bv human physioclimatic reactions in Korea. Human physiological reactions to temperature and relative humidity are analyzed to produce a nomogram from which average human reactions to the climatic factors can be deduced. Thermal - indices for each regular stations in both South (1961-1990) and North Korea(1973-1994) are calculated based on monthly meteorological data. A generalized annual physioclimatic maps for each Annual Cumulative Thermal Index for the 52 stations are constructed to show how men tend to feel in various areas. Resuts of this study can be applied for evaluation of thermal environment in our daily activities, and for searching relevant sports training-sites.

Our fossil fuels will be exhausted and replaced with renewable energies over tile next few decades. And rapidly increasing consumption of primary makes every country recognize the potential significance of climate change and necessity of greenhouse gas reduction. A critical part of the solution is to ratify the Kyoto Protocol and the UNFCC, and to develop and utilize the wind energy. One of the renewable energies, wind energy is increasing competitive in liberalised energy markets and shows annual growth rate of $20\~30\% in past five years. Thus, the purpose of this paper is to describe the necessity and characteristics of wind energy industries, to compare the international development policies of wind energy industries, and to suggest and discuss the alternative development policies of wind energies in Korea

Implementing proper land management techniques, such as selecting the best crops and applying the best cultivation techniques at the farm level, is an effective way for farmers to adapt to climate change. Also it will be helpful if the farmer can get the information of agro-weather and the growth status of cultivating crops in real time and the simulated results of applying optional technologies. To test this, a system (web site) was developed to produce agro-weather data and crop growth information of farms by combining agricultural climate maps and crop growth modeling techniques to highland area for summer-season Chinese cabbage production. The system has been shown to be a viable tool for producing farm-level information and providing it directly to farmers. Further improvements will be required in the speed of information access, the microclimate models for some meteorological factors, and the crop growth models to test different options.

Crop estimation is essential for the multinational meal and powerful demand due to its numerous aspects like soil, rain, climate, atmosphere, and their relations. The consequence of climate shift impacts the farming yield products. We operate the dataset with temperature, rainfall, humidity, etc. The current research focuses on feature selection with multifarious classifiers to assist farmers and agriculturalists. The crop yield estimation utilizing the feature selection approach is 96% accuracy. Feature selection affects a machine learning model's performance. Additionally, the performance of the current graph classifier accepts 81.5%. Eventually, the random forest regressor without feature selections owns 78% accuracy and the decision tree regressor without feature selections retains 67% accuracy. Our research merit is to reveal the experimental results of with and without feature selection significance for the proposed ten algorithms. These findings support learners and students in choosing the appropriate models for crop classification studies.

현대 산업사회는 시장의 불확실성과 기술의 불확실성이 공존하면서, 글로벌 경제의 저성장에 대한 우려, 불확실성의 증대가 더욱 크게 산업 전반의 스트레스로 작용하고 있다. 이는 R&D-생산-마케팅 자원의 낭비를 초래하게 되고, 시대/경제/산업의 변화는 더욱 이러한 환경을 가속화시키고 있다. 에너지 분야에서도 환경 위기, 지속가능 에너지, 화석연료 고갈, 기후변화 등의 당면 문제를 해결하지 못한다면, 인류 공멸의 위기에 직면할 것이다. 정부에서는 창조경제의 주요 아젠다로 에너지 분야의 다양한 정책과 기술개발을 드라이브하고 있으며, 에너지 ICT 융합을 통해 이를 실현하고자 하고 있다. 본고에서는 에너지 ICT 기술의 개발동향과 발전방향 및 트렌드를 분석해 보고, 현재 진행 중인 국내(ETRI)의 기술개발 사례를 소개하고자 한다.
