The performance prediction software developed in this paper is a process analysis tool that enables one to foretell the behavior of processes when certain conditions of operation are altered. The immediate objective of this research is to predict the process characteristics of combined heat and power plant under varying operating conditions. A cogeneration virtual power plant that mimics the mechanical performance of the actual plant was constructed and the performance of the power plant was predicted in the following varying atmospheric conditions: temperature, pressure and humidity. This resulted in a positive outcome where the performance of the power plant under changing conditions were correctly predicted as well as the calorific value of low calorific gas fuel such as shale gas and PNG. The performance prediction tool can detect the operation characteristics of the power plant through the performance index analysis and thus propose the operation method taking into consideration the changes in environmental conditions.

This a a system for assessing quantitatively the comprehensive, unified performance of housing by an objective standard from the design stage since January 9, 2006. As housing is a composite with various performances, it is required necessary to objectively assess the various performances from the design stage for building better housing. Thus, this study analyzed the change status and objectively described objectively it centering on the construction and structure drawings for 12 items posted in the Facility Management System_(FMS) out of examples recognized by 2011 since the implementation of the system. The changes were analyzed though observing each performance item-specific characteristics and confirming the books approved for use. In various parts, such as the site area, landscape plan, plane plan for unit, supplementary welfare facility plan, finishing materials, window size and location, the project plan was changed. These changes may result in a grading change in of the performance items of the system. This study purpose is for it to be used as a basic resource required for future system development by supplementing the limitation of the design phase and then through playing a basic role for the assessment after completion.

The objective of this study was to investigate the effect of the perceived importance of kitchen equipment and facilities on the hygienic performance of cooks in deluxe hotels. Cooks and chefs at 7 different deluxe hotels participated in this study. Out of 490 questionnaires administered, 456 (93.1%) were completed and 419 (91.9%) were analyzed using a statistical package SPSS 12.0. The results were as follows. First, the correlation between sanitary equipment, including HACCP system, in the hotel kitchens and the hygienic management performance confirmed the significant effect of the sanitary equipment on the performance of the cooks and chefs. Second, the sanitary facilities in the hotel kitchens greatly affected the hygienic management performance. The results also demonstrated that the sanitary equipment provided the same contribution to the performance irrespective of the job level, management type and HACCP practice. However, the sanitary facilities greatly affected the management type expecially the chain hotels. The hygienic management performance did not affect the cooking stage (before-cooking and during-cooking), but affected the after-cooking stage according to the management type and the HACCP practice, but not the job level.

The necessity of remodeling performance grading system is getting increased for the systematic management of existing housing stock, providing the resident's right to know and promoting the remodeling projects. A quantitative and objective evaluation method that has reflected the characteristics of remodeling must be developed because there is an aspect of having difficulty of assessment by an ordinary person as remodeling performance contains specialized details while the difficulty of applying the criteria of new buildings in terms of assessment items, criteria and methods. Accordingly, this study sets the goal as setting up the development objectives of performance grading system that has considered the remodeling characteristics. This study has analyzed the various assessment systems related to the domestic apartments as well as setting up the organization system of the remodeling performance grading system, perspectives of performance assessment and scope of assessment through literature, etc. It has also established the principles for setting up the assessment items of remodeling performance grade to present the directions for setting up assessment items and criteria.

The purpose of this study was to explore the possibility of mathematical instruction through performance task activities based on the The Backward Design, which was suggested at first by Wiggins & McTighe in 1998. The Design deals with a performance assessment task involving the whole objective and its entire content of a lesson. Based on the Backward Design, this study established the mathematical instructional materials, which deal with the concept of 'the sector' taught in middle school, with one large performance task including three small tasks. It is important that in the lesson students be guided to achieve the several learning goals by themselves through reasoning activities. For this purpose, a formal interview was carried out by the subject of three middle school mathematics teachers. As a result, in order to implement the instruction utilizing the performance tasks more efficiently in future, it is required that a large performance task should be selected or developed including the content or problem contexts to be relevant with the real-life challenging situations. In addition, to make students enhance reasoning skills, it is strongly requested that the tasks including the utilization of supplementary materials such as technological devices or manipulatives be dealt with in a lesson.
