This study characterized fly ash produced from a sewage sludge incineration facility in Korea to determine if the byproducts can be utilized. All the incinerated sewage sludge was from a city in Korea. To characterize fly ash and to determine if it can be utilized, pH, water contents, elemental components, particle size, surface morphology, heavy metal compositions, and others were analyzed. In average, pH was 6.2, and water contents was about 5%. T-N and $T-P_2O_5$ were 3% and 24.5%, respectively. Particle size averaged 836 nm; surface morphology did not exhibit any significant results. X-ray diffraction (XRD) analysis results revealed that major components of the fly ash were $P_2O_5$, CaO, MgO, $K_2O$. Composition of heavy metals by the Korea Standard Methods for Waste Quality did not exceed the criteria for specified wastes in Korea.

Recently, as the environment issue has been stand out, people's interests in energy consumption of the building have been increased as well. Especially, university has been classified as the one of the main causes of excessive energy consumption. Therefore, domestic and foreign universities are trying to build a green campus in an attempt for sustainable development. Since early 2000s, foreign universities have been aware that one of the main causes of global warming is an excessive consumption of energy in universities. Accordingly, they adopted various energy management programs for the conservation. Ultimately, enforcing energy conservation and using alternative energy resulted in lower expense and it was a great help for the universities. On the other hand, excessive consumption of energy in domestic universities has been considered as serious, which led them to become the second main energy consumers in 2010. However, it seems people do not truly recognize the impotance of energy management, therefore, relatively little attention has been paid to this matter. Based on Leadership in Energy & Environmental Design(LEED) rating systems for on-campus building operation and maintenance, this research suggests the evaluation standard to effectively analyze the energy management activity with the best practices conducted in foreign universities and to solve the problem of campus facilities management in domestic universities. The result shows that domestic universities do not have a designated task force for effective energy management and the lack of energy professionals hinders for the long term development. Therefore, domestic universities should recognize the seriousness of the excessive energy consumption and develop low carbon green campus through proactive management practices since this is very essential for domestic universities to get more competitive in this global era.

Not only the education that follows the school curriculum but also the education that cultivates practical abilities, such as creative experiential activity, is becoming more and more important in the elementary education in order to accept the social demand about the change in the educational environment. Among these movements, 'village-coupled school' has been carried forward as a policy of the Seoul Metropolitan Office of Education since 2016, and it is operating various programs to establish the educational cooperation system of schools and villages. Particularly, each office of education is publishing the 'village resource sourcebook' and introducing the student experiential programs of public facilities that are located at each region in order to enable the experiencing of experiential activities that utilized educational resources of the region. However, the standard or basis about the composition of the regional experiential learning curriculum is currently missing. Regarding the operation of the regional experiential learning, it seems that the school curriculum and associated facility experience or others would mutually increase the educational synergy effect. This research is a proposal to increase the educational effect of regional experiential learning. In the aspect of the experience at a public facility located in the region, it aims at analyzing the use, characteristic, and others of public facilities that appear in the elementary school textbook and propose the base data of the composition of the experiential activity program related to the curriculum.

In this study, we have created CityGML based 3D information model for drainage facility, manhole and terrain. It conducted analysis of the rainfall-runoff leak through the information model for obtaining interoperability for information integration between city models. The models have advantages to manage the infrastructure information in point of semantic meaning and geometric information by converting the original 2D GIS construction information into the 3D information model. The input values can be automatically generated through the 3D information model of this study, while the values should be entered manually in the conventional method. Also, it can be useful to check the flooding level and related locations by connecting the result of rainfall interpretation and information model.

As the development of total management systems for sites along with site environmental information is becoming standard, the system known as the Site Information and Total Environmental database management System (SITES) has been developed over the last two years. The first result was a database management system for storing data obtained from facilities, and a site characterization in addition to an environmental assessment of a site. The SITES database is designed to be effective and practical for use with facility management and safety assessment in relation to Geographic Information Systems. SITES is a total management program, which includes its database, its data analysis system required for site characterization, a safety assessment modeling system and an environment monitoring system. It can contribute to the institutional management of the facility and to its safety reassessment. SITES is composed of two main modules: the SITES Database module (SDM) and the Monitoring & Assessment (M&A) module [1]. The M&A module is subdivided into two sub-modules: the Safety Assessment System (SAS) and the Site Environmental Monitoring System (SEMS). SAS controls the data (input and output) from the SITES DB for the site safety assessment, whereas SEMS controls the data obtained from the records of the measuring sensors and facilities. The on-line site and environmental monitoring data is managed in SEMS. The present paper introduces the procedure and function of the M&A modules.
