This study aims to investigate the possibility of expanding the support program for green remodeling of fire stations and analyze the standard design guidelines. Green remodeling is essential for reducing greenhouse gas emissions and promoting green buildings, but currently, it is only conducted for buildings with limited purposes. In this study, we conduct green remodeling for fire stations with severe aging to demonstrate energy performance improvement and investigate the potential for expanding the support program to other types of aging buildings. The research methodology includes analysis of previous studies, preliminary investigation and alternative setting, energy analysis, calculation of construction costs, evaluation of the possibility of introducing support programs, and examine of the fire station standard design guidelines. The research results confirm that green remodeling can reduce energy consumption in fire stations and present the possibility of including fire stations as targets in the support program for green remodeling of public buildings.

Solutions to improve collaborative energy-saving programs were developed as follow; First, the scoring for the selection of the programs between KEMCO and the NGOs' Energy Network needs to be adjusted. Second, solutions were proposed to diversify the network selected to participate in programs and to tighten the network among the participating citizens. Third, improving the compatibility with the targets that are set for the program and raising the program budget was proposed. Fourth, ideas to introduce the final evaluation guidelines for the programs by the network, to improve the convenience of the program procedures. Fifth, developing a manual to inspect energy-saving measures in households, counseling for at-home energy-saving behaviors, sharing search programs such as financial support and home repair, introducing a program energy-saving APPs.

In this study the thermal performance and economic analysis program of solar heating system for district heating was developed. This program, named SOLAN-DHS and based on TRNSYS, consisted of four modules like as user's interface for system input/output, library, and utilities and a calculating engine. SOLAN-DHS simplifies user's input data through the database of most system engineering data including weather data of 17 areas in Korea. Five different types of solar systems which can be applicable to district heating system were presented in this program. Due to the user-friendly layout, all design parameters can be changed quickly and easily for the influence on system efficiency. The reliability of SOLAN-DHS was finally verified by the experiments.

In order to reduce the cost of software maintenance including software modification, we suggest the object oriented program with checking the version of application program using the Java language and the technique of executing the downloaded application program via network using the application manager. In order to change the traditional scheduler to the application manager we have adopted the Xlet concept in the nuclear fields using the network. In usual Xlet means a Java application that runs on the digital television receiver. The Java TV Application Program Interface(API) defines an application model called the Xlet application lifecycle. Java applications that use this lifecycle model are called Xlets. The Xlet application lifecycle is compatible with the existing application environment and virtual machine technology. The Xlet application lifecycle model defines the dialog(protocol) between an Xlet and its environment

STEAM education is an effective teaching method to develop self-problem-solving skills through creative thinking. In order to revitalize STEAM education, various program models are being developed recently. The purpose of this study is to develop a STEAM education program based on the project-based learing method that includes the process of solving global environmental problems. The STEAM element was extracted by linking the zero energy house design with the middle school curriculum, and the STEAM education program was developed considering career activities. It was analyzed whether the developed program can improve STEAM core competence and job preparation ability. The education program was conducted for middle school students and the program was evaluated through questionnaires. In order to strengthen the STEAM competency, project-based learning method was applied and it was able to enhance the active problem solving ability of learners. In addition, opportunities for career experience could be provided through career exploration programs and various activities. Through this STEAM education program, it is expected to contribute to cultivating human resources with convergence knowledge and core competency.

We have surveyed on microcalorimetry which we can treat with energy dispersive spectrometer(EDS) as wavelength dispersive spectrometer(WDS), to be developed in order to make higher energy resolution as to detect X-ray peak as high as wavelength dispersive spectrometer(WDS). When we take into consideration about energy resolution, Wavelength dispersive spectrometer is 2~20eV and energy dispersive spectrometer is 140~180eV.

Many oil refinery companies have been proactively carried out marketing activities to survive in highly intensified service station industry. In 2012, SK Energy ranked number one in three customer satisfaction surveys (NCSI, KCSI, and KS-SQI). SK Energy's success is in its differentiated customer satisfaction business strategy. SK Energy has been implementing various marketing activities. As a part of the activities, it issued an affinity credit card with on spot discount privilege for the first time in the oil refinery industry. SK Energy also issued EnClean bonus card for OK Cashbag points that can be used for discounts at the service stations. On top of all, SK Energy generated point value-up with '3K Exclusive Privilege' program. In addition, team 'CS 119' was formed to noticeably improve the service. 'CS 119' visited each service station, diagnosed its CS service level then provided customized field training for improvement. Long-termimplementation of 'ACE Program', a field-base CS monitoring system, regularly checked customer satisfaction level. 'ACE Program' has significantly contributed improving SK Service Station's service quality and customer satisfaction. This case reviews customer satisfaction marketing activities SK Energy carried out. The focus is on distinctive factors that distinguish SK Energy's customer satisfaction marketing activities from competitors.

The objectives of this study are to introduce the energy simulation program BLDSYM, to verify the approach, and to demonstrate the energy saving opportunities. A case study model for Hoover Middle School, OK, USA has been introduced as a base case simulation. Air-side variable air volume(VAV) and water-side variable flow hydronic(VFH) system have been recommended, modeled and simulated to quantify the energy savings compared with the base system, which is typically constant air and water flow system. More than 30% of energy savings could be obtained with the optimum variable flow system.

The geological research as a part of HLW disposal program in Korea is carried out to provide necessary data for the establishment of the reference repository system in term of design and safety assessment in the crystalline rock terrains. Six deep boreholes were drilled to obtain hydrogeological and hydrochemical data from Jurassic granites in the Yuseong area, Korea. The core observation, televiewer logging and hydraulic testing were carried out during and after drilling and multi-packer system were installed in the boreholes of 500m depth for hydraulic and hydrochemical monitoring including environmental isotopes. The integration of hydrogeochemical and hydrodynamic data would be built greater confidence for the understanding of groundwater system in fractured rock mass. This geoscientific program could be possible to suggest a general guideline to develop the reference disposal concept of high-level radioactive waste in Korea.
