There are lots of buildings which were built before the Legislation on building energy rating system. Remodeling of the buildings would be required for an improvement of the building energy rating system was enforced by the government. In the Passive Building Design, Elements which will be used for the remodeling are Insulation, Window, External venetian blind, Heat exchanger. The Purpose of this study is to indicate a Method for the improvement of Energy saving by an analysis of Construction Cost, Cost Evaluation, Energy performance Efficiency in applied design elements. In this study, the remodeling of existing public buildings to improve energy efficiency rating was applied to extract the elements of design-specific energy performance, efficiency, and the application of the designs that has been analyzed. The results were as follows: applying the design-specific cost-effective investment that represents the economy (investment efficiency/%) surveyed the average insulation(7.0%), triple glazed windows(10.1%), double glazed windows(12.1%), external shading(24.5%), and Heat(77.2%) were analyzed in order to be more efficient. Analysis of the basis of information on the existing public buildings to improve energy efficiency rating for the remodeling depending on driving conditions at a degree of individual difference. The main effect, however, depending on economic investment, design elements, heat exchangers, external awning, double glazed windows, triple glazed windows, insulation, is recommended as review of the order shall be determined.

As part of alternative of elderly problems in the future super-aging society, this study aims to extract an improvement plan of interior environment design of Seoul-type day care centers to expand in future by observing day care centers as medical and healing environments, from the perspective of user experience. For this study, after selecting major activity areas of representative cases of Seoul-type day care centers, user behaviors in the space were observed and 4 seniors of baby-boom generation who are potential uses were chosen as personas by reflecting characteristics of healthy elderly, physical aging, mental aging and infirm elderly, from the perspective of user experience. Based on previous studies on healing environments, these characteristics and demands of personas were classified into environmental aspects, physical aspects and mental aspects to extract an improvement plan. The study results are as follows. First, interior environment design reflecting persona characteristics helps the elderly adapt to the environment and provides a comfortable environment like home for stability, treatment and recovery of memory. Second, interior environment design reflecting persona characteristics helps psychological healing through light entering the large windows and natural environment elements. Third, for interior environment design reflecting persona characteristics, finish materials with bright and soft colors should be used to change the images of facilities positively. Fourth, spatial composition should be remedied through division of space and built-in furniture depending on the needs of users for loitering of extra time and programs.

This study was done for the proposal for improvement for junior sportswear which is substitutable as uniforms in the form of elementary school and physical education uniforms by analyzing detailed features through investigation. Accordingly, we developed a prototype design for physical education uniforms as a symbol of the school to enhance the aesthetic and functional satisfaction. The results are as follows. When we developed physical education uniforms, we put activity on our first priority while taking the improvement in both aesthetic and functional aspects into consideration. In addition, we tried to make sure the uniforms reflect the refined and trendy elements to meet students needs to satisfy their aesthetic sense in dress. Reflecting the improvement proposals and preferences of the students, six different prototype designs were developed and evaluated on the basis of two concepts of "new basic" and "trendy". The highest ranking, the physical education uniforms design 1 is based on new basic concept and characterized with slim fit considering activity which will be worn as fall/winter physical education uniforms. Design 1 uses ottoman functional knit as a fabric material which is not only students favorite but also good in both flexibility and warmth. Top with style of high-neckline collar and full open zip-up is simplified with the incision lines and detail. It is a set-in sleeve design in which blue and yellow collars signifying school color are properly placed along with the incision lines in harmony.

민감도 해석은 어떤 설계 변수의 변화가 전체 시스템에 미치는 영향을 확인하기 위한 방법으로, 계산된 민감도는 구조개선 시 중요한 지표가 된다. 본 연구에서는 유한요소해석을 이용하여 설계 변수에 대한 민감도 도출 및 분석 방법과, 민감도 결과를 활용한 구조개선 방법을 제안하였다. 구조 개선이 필요한 실제 반도체 검사 장비를 이용하여 경량화를 위한 설계 변수를 선정하고 설계 변수에 대한 민감도를 유한요소법과 유한차분법을 활용하여 계산하였으며, 장비가 요구하는 과도응답(Transient Response)은 유지하면서도 무게 감소가 가능한 개선 방안을 제시하였다. 유한요소해석과 유한차분법을 이용한 민감도 분석 결과를 이용한다면 구조물의 설계 개선 시 원하는 응력 또는 변위는 만족하면서도 구조적으로 향상된 설계를 할 수 있고, 이는 반도체 검사 장비뿐만 아니라 다양한 분야에서 활용이 가능하다.

The building remodeling is providing a lot of solutions - structural, aesthetic, environmental, and energy performance improvement - in improving buildings performance and environment. The remodelings influences on our society are resource conservation, environmental conservation, expansion of construction market, and creation of new employment. The three principal remodeler groups involved in this building remodeling are general construction contractors, interior architecture contractors, and ESCO (Energy Service Company). Having a representative character, this study classifies remodeling methods into five types: structural remodeling, spatial remodeling, exterior remodeling, environment-friendly remodeling, and ecological remodeling.

In this paper, to propose guideline of modular design for improvement of ease of disassembly, product structure must be considered. By analyzing characteristics of structure of subassembly, influencing factor of module can be defined and classified. Based on determination factor of influencing factor of module, criteria for improvement of ease of disassembly can be obtained through the interrelationship between product and process factors.

Since the urban subway is normally constructed under the groundwater level, the drainage system will be one of the most important factors during maintenance period. Therefore, to investigate suitability of the design approach and the construction specification, the inflow and the contents of the groundwater in the Route 5 of Seoul subway system are analysed. From these, the possibility of the design improvement and the economy of the maintenance cost are proposed.

Iterative learning control is an approach to improve the transient response of systems that operate repetitively over a fixed time interval. It is useful for the system where the system output follows the different type input, in case of design or modeling uncertainty In this paper, we introduce the concept of iterative learning control and then apply the learning control algorithm for multi-motor system for performance Improvement.

The Korean government has developed and strengthened energy related regulations to pursue eco-friendly buildings since 1979. However, required design standards for energy based quantitative studies focused on energy performance in existing buildings are meagered. Therefore in this study, required energy performance by design standards for energy are analyzed. And a energy performance by retrofits for insulation improvement is studied using energy simulations.

The objectives of this research are 1) control of schedule or improvement of management for aerial environment, 2) distribution of responsibility to the parties concerned (factory, material company, construction company, design and engineering, occupancy). The results show the relative priority of the four major items in wall-based apartment buildings and in column-based apartment buildings. An analysis of the parties responsible for improvement based on the IAQ results shows more efforts to improve IAQ are needed in material factories and engineering/design companies.
