China is experiencing the urbanization at an unprecedented speed and scale in human history. The continuing growth of China's big cities, both in city land and population, has already led to great challenges in China's urban planning and construction activities, such as the continuous increase of construction and demolition (C&D) waste. Therefore, how to characterize cities' construction activities, particularly dynamically quantify the flows of building materials and construction debris, has become a pressing problem to alleviate the current shortage of resources and realize urban sustainable development. Accordingly, this study is designed to employ 4D-GIS (four dimensions-Geographic Information System) and Internet Plus to offer new approach for accurate but dynamic C&D waste management. The present study established a spatio-temporal pattern and material metabolism evolution model to characterize the geo-distribution of C&D waste by combing material flow analysis (MFA) and 4D-GIS. In addition, this study developed a mobile application (APP) for C&D waste trading and information management, which could be more effective for stakeholders to obtain useful information. Moreover, a cloud database was built in the APP to disclose the flows of C&D waste by the monitoring information from vehicles at regional level. To summarize, these findings could provide basic data and management methods for the supply and reverse supply of building materials. Meanwhile, the methodologies are practical to C&D waste management and beyond.

Objectives : This study aims to investigate the effectiveness of an internet-based anger management program for school-aged children. Methods : Forty-eight elementary school students took part in an anger management training program; subsequently, participants, their parents, and their teachers answered questionnaires assessing the participants' anger, aggressiveness, and other emotional/behavioral problems, pre- and post-training. Results : At the post-training self-assessment, the participants showed significant reductions in their "anger-out" tendencies and physical aggressiveness. In addition, the effects of the program on "anger-out" tendencies, aggressiveness, anger and peer relational problem were found to be more significant in participants who reported depressive symptoms. Teachers rated the participants' peer-relational problems as having decreased after the training. Conclusion : The proposed internet-based anger management program had a significant effect on the school-aged children's abilities to control their anger.

This study attempted to investigate use of information for school foodservice management and perception of informations offered on Office of Education homepages according to Daegu and Gyeongbuk nutrition teachers and dietitians. The most frequently used web site information source and information type were 'charged foodservice information sites'(63.5%) and 'information on nutrition or menus'(63.5%), respectively. Subjects belonging to schools that served more meals per day tended to use informations more frequently. Information on 'management of the foodservice production process' showed a low satisfaction level as compared to importance in all groups, and information on 'nutrition education' showed a similar tendency for subjects belonging to schools that served 1 meals per day. Overall, efforts for development and dissemination of information are required to improve the quality and efficiency of school foodservice.

Development of information and communication technologies has given a lot of changes in the business processing methods including the school and class managements. However, many business processing systems are still based on desktop computer. In particular, most of the class management system only supports desktop computers; hence school teachers have difficulty in using their class managements systems on mobile environment. In this paper, we proposed and developed a mobile classroom management system for teachers, which will easily handle information such as personal records of students, student counseling records, student life record and so on. The implementation of the application of mobile-based class management can be managed by many school elements including student register information, student evaluation records and transcripts, counseling report, and so on.

A hybrid switch that uses a microelectromechanical system (MEMS) switch as a gate driver of a MOSFET is applied to an energy harvesting system. The power management circuit adopting the hybrid switch provides ultralow leakage, self-referencing, and high current handling capability. Measurements show that solar energy harvester circuit utilizing the MEMS-MOSFET hybrid switch accumulates energy and charges a battery or drive a resistive load without any constant power supply and reference voltage. The leakage current during energy accumulation is less than 10 pA. The power management circuit adopting the proposed hybrid switch is believed to be an ideal solution to self-powered wireless sensor nodes in smart grid systems.

The purpose of this study is to provide the necessary data for the effective performance of school nurse's work by comparing with the recognition and expectation on school nurse's work by the students and their teachers in school settings. The sample of this study was consisted of the 441 students and 535 teachers in Suwon. The data were collected by means of a structured questionnaire from 24th, Sept, to 29th, Sept. 1990. The collected data were analyzed utilizing SAS/PC program for percentage, frequency, mean, standard deviation and chisquare test. The major findings of this study were as follows: 1. The result of analysis in recognition on school nurse's work. There is no statistically significant difference 'depending on teachers' school level, sex, age and career with school nurse(P>0.05). The students show significant difference on their school level and sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest recognition and school environment management has the lowest recognition. 2. The result of analysis in expectation on school nurse's work. There is statistically significant difference depending on teachers' and students' school level: the order of expectation is elementary, middle, and high school(P<0.05). In the result of comparison with students' and teachers' expectation in the same school level, there is significant difference only in elementary school(P<0.05). However, there is no statistically significant difference depending on teachers' sex, age, career with school nurse and students' sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest expectation and school environment management has the lowest expectation. Synthesizing the result of the study, we can have the conclusion like following. First, students' recognition on school nurse's work is lower than teachers' because most of school nurse's work is performed through their homeroom teachers or other teachers. That can be the limitation for students to recognize school nurse's work. So, there must be a chance of regular meeting between school nurse and students to perform school nurse's work effectively. For this. we must change our educational system and make school nurse charge regular lesson. Second, in each area of school nurse's work, both students' and teachers' recognition and expectation about the area of school environment management has much lower score than the other areas. This indirectly shows the school nurse don't do the work of the area actively. So, school nurses must make an effort to do the work of the area actively. And we must enforce the education of this area in education for new school nurses or re-education for school nurses.
