We present the motivation, design and implementation of a smart home system in Korea. Our system is open, extensible, integrated, intelligent, and usage-centric. We detail the challenges and key design requirements for the smart home system based on our past experiences, and show how convergence system design is a capable methodology for enabling an integrated and multi-faceted home management system that encompasses energy management, home appliance control, environment management, u-health, and living support functionalities under a single unified design. Using energy management as a specific case study, we demonstrate how convergence system design can encapsulate technology heterogeneity and hardware-software disparity without compromising simple yet powerful user interfaces.

Since the introduction of the Departmentalized Classroom System in 2009, schools that operate the system experienced many changes in terms of school management, educational courses, and school environment. In particular, class-based classrooms changed into departmentalized classrooms and staff rooms became teachers' support centers and research rooms to create an environment that is apt for the management of departmentalized classrooms. Students have also come to move from departmentalized classrooms to departmentalized classrooms in which homebases were prepared as a space for students to rest and enjoy a stable school life. As such, homebases as a space for students to enjoy school life are indispensable and are becoming more important for the management of the Departmentalized Classroom System. Thus, it is necessary to investigate in detail the state of the establishment of homebases in schools that operate the system. In line with this, this paper sampled 59 schools that have managed the system as an advanced system for over 2 years and conducted school visits and held interviews to investigate and analyze the placement, function, and scale of homebases as well as to provide basic material on homebases.

As the industry develops, the amount of wastes is increasing in the economic system with various needs. As a result, the environmental problems are emerging as serious social issues and all the parties are required to make their best efforts. Among the issues proposed as the environmental issues, the logistics-related issues are exhaustion of the resources, global warming, environmental pollution, and acidification and so on. In order to respond to the environmental issues of the earth, the advanced countries are setting retrenched goals, reduction of the new greenhouse gases and accomplishment of retrenched goals by cooperation between the nations. Economic activities inevitably bring environmental problems and logistics is implementing those activities. The companies should perform the roles to resolve the environmental problems as the main cause of environmental pollution. Therefore, along with spreading recognition of social demand, the companies are required to establish policies regarding the environment and they should approach the issues from the perspective of resource circulation. These environment-friendly activities are emerging as the new source of competitiveness in the logistics field. Therefore, this study analyzes the effects of environment-friendly logistics activities on the reduction of logistics cost to reduce and resolve the environmental issues such as environment preservation, recycling and so on.

BACKGROUND: Phosphorus(P) is a vital factor for rice but excess input of phosphorus fertilizer can cause environmental risk and waste of fertilizer resources. We studied to assess the change of available phosphate, P balance, critical concentration of available phosphate under a rice single system. METHODS AND RESULTS: The changes of available phosphate of paddy soil were examined from long-term fertilization experiment which was started in 1954 at the National Academy of Agricultural Science. The treatments were no phosphate fertilization(No fert., and N), phosphate fertilization(NPK, NPKC, and NPKCLS). The available phosphorus concentrations in treatments without phosphate fertilizer (No fert. and N) were decreased continuously. But, after 47 years, available phosphate content in phosphate fertilizer treatment (NPK, NPKC, and NPKCLS) reached at the highest ($245{\sim}331mg\;kg^{-1}$), showing a tendency to decrease afterward. The mean annual P field balance in these treatments (NPK, NPKC, and NPKCLS) had positive values that varied from 16.6 to $17.5kg\;ha^{-1}year^{-1}$, and ratio of residual P were increased. These showed that phosphate fertilizer in soil were converted into the form of residual phosphorus which was not easily extracted by available phosphate extractant. Also, It was estimated that the critical value of available phosphate for rice cultivation was $120mg\;kg^{-1}$ using Cate-Nelson equation. CONCLUSION: We concluded that no more phosphate fertilizer should be applied in rice single system if soil available phosphate is higher than the critical P value.

Remote sensing(RS)- and geographic information system(GIS)-based information management to measure and assess agri-environment schemes, and to quantify and map environment indicators for nature and land use, climate change, air, water and energy balance, waste and material flow is in high demand because it is very helpful in assisting decision making activities of farmers, government, researchers, and consumers. The versatility and ability of RS and GIS containing huge soil database to assess agricultural environment spatially and temporally at various spatial scales were investigated. Spectral and microwave observations were carried out to characterize crop variables and soil properties. Multiple sources RS data from ground sensors, airborne sensors, and also satellite sensors were collected and analyzed to extract features and land cover/use for soils, crops, and vegetation for support precision agriculture, soil/land suitability, soil property estimation, crop growth estimation, runoff potential estimation, irrigated and the estimation of flooded areas in paddy rice fields. RS and GIS play essential roles in a management and monitoring information system. Biosphere-atmosphere interection should also be further studied to improve synergistic modeling for environment and sustainability in agri-environment schemes.
