Climate change is the biggest environmental issue of our times. A variety of activities to reduce greenhouse gas emissions have been in progress to observe the Kyoto Protocol. Especially, the Energy Target Scheme is created to reduce greenhouse emission with the supervision of Korean government. This includes Green-house Gas Information Systems to promote activities in the private sector to reduce green-house gas emissions, to cut a cost of energy use, and to reduce GHG emissions. Also, the system has calculated the amount of greenhouse gases. Without any additional investment, 2.75% savings are increased over the previous year. In service sector, a cooperation of customers and employees is necessary. A reduction of GHG emissions requires a proper service organization, considering an amount of investment and payback period. Without any additional investment or replacement, employees can save energy easily turning off ventilation systems an hour before employees’ departure, installing timers to turn off water purifiers and vending machines after some period of no use. The Green-house Gas Information System is similar to that of Environmental Management System. However, the Excel is the best program to calculate an amount of green-house gas emissions, and to assess for a reduced amount of GHG emissions. A goal of this research is to propose a practical method in the private sector to calculate an amount of green-house gases. The Green-house gas Information System based on Excel spreadsheet gives standards for good evaluation. The greenhouse gas information system establishes and executes the policies and objectives related to greenhouse gas emissions Similar to ISO 14001 environment management system structures, the advantages of using simplified Excel Sheet for calculating GHG emissions and reducing GHG emissions are easy to access.

Climate change has been identified as one of the greatest challenges facing nations,government, business and citizens over future decades. Activities to reduce greenhouse gas emissions by the Kyoto Protocol, the international community has been in progress. Korea also has introduced the green house gas and energy Target Scheme to reduce greenhouse emission under the supervision of the government. Established green house gas information systems to promote activities of the private sector to reduce greenhouse gas emissions, The main propulsion is intended to be used as a basis in the private sector to reduce greenhouse gas utilized in the calculation of greenhouse gas emissions program (Excel spreadsheet), and to reduce greenhouse gas emissions evaluation standards published.

Belleville springs can sustain relatively large loads with small deflections and belleville spring washers are especially suited for high loads in small places. Belleville springs are used singly or in stacks to achieve desired load such as power transmission components. The aim of this paper is to design for the belleville spring diameter and thickness to minimize volume of the system. The design is carried out using finding solution in a commercial spreadsheet application software, Microsoft Excel 2007. The numerical results are obtained where the displacement, stress and load in the spring are treated as constraints function.

The purpose of this thesis is to develop a performance rating training tool for the time and motion study. It is widely recognized that rating training tools based on films were made several decades ago and introduced to Korea. However, to the best of our
