As people abroad have been much interested in the usage of modern architecture from the early days, many researches about various methods of using them have been progressed. In Korea, with the need to protect the modern architecture through active usage of them in the dimension of protecting the disappearing history, at present, many modern architectures were renovated and used. This research is to find out the sense of direction about the changes of design of the renovated modern architectures in Korea by analyzing the design changes after the renovations in Korea and abroad. Under the limitation of the modern architecture renovation case in Korea, Japan and China, the changes of design after the modern architecture renovation in Korea and aborad were analyzed by the analysis of the ways of remodelling for each case according to the case analyzing frame. Based on the reasons of renovations which had purpose of preserving social history with many other various reasons in common in both cases of Korean modern architecture remodelling and abroad, the common direction of design is to meet new with old to preserve the special image though they did it in different ways. However, different from the case of Japan and China which are coexisting present and past in space, Korean case focused too much on outside, which resulted in only outside designs. In the case of Korea, the past should have mutual understanding to have the firm space image by forming unique interior space culture through the architectural grafting the present in the past not only in the outside space but also in the indoor space. In another words, for the various changes of design in Korean modern architecture renovations, a systematic research should be done about the interior spaces of present architecture and modern architecture.

For efficient design process of regenerative blower, the present study provides new generalized pressure and leakage flow loss models, which can be used in the performance analysis method of regenerative blower. The present performance analysis on designed blower is made by incorporating momentum exchange theory between impellers and side channel with mean line analysis method, and its pressure loss and leakage flow models are generalized from the related fluid mechanics correlations which can be expressed in terms of blower design variables. The present performance analysis method is applied to four existing models for verifying its prediction accuracy, and the prediction and the test results agreed well within a few percentage of relative error. Furthermore, the present performance analysis method is also applied in developing a new blower used for fuel cell application, and the newly designed blower is manufactured and tested through chamber-type test facility. The performance prediction by the present method agreed well with the test result and also with the CFD simulation results. From the comparison results, the present performance analysis method is shown to be suitable for the actual design practice of regenerative blower.

Present paper deals with the cost effective design of reinforced concrete building frame employing unified particle swarm optimization (UPSO). A building frame with G+8 stories have been adopted to demonstrate the effectiveness of the present algorithm. Effect of seismic loads and wind load have been considered as per Indian Standard (IS) 1893 (Part-I) and IS 875 (Part-III) respectively. Analysis of the frame has been carried out in STAAD Pro software.The design loads for all the beams and columns obtained from STAAD Pro have been given as input of the optimization algorithm. Next, cost optimization of all beams and columns have been carried out in MATLAB environment using UPSO, considering the safety and serviceability criteria mentioned in IS 456. Cost of formwork, concrete and reinforcement have been considered to calculate the total cost. Reinforcement of beams and columns has been calculated with consideration for curtailment and feasibility of laying the reinforcement bars during actual construction. The numerical analysis ensures the accuracy of the developed algorithm in providing the cost optimized design of RC building frame considering safety, serviceability and constructional feasibilities. Further, Monte Carlo simulations performed on the numerical results, proved the consistency and robustness of the developed algorithm. Thus, the present algorithm is capable of giving a cost effective design of RC building frame, which can be adopted directly in construction site without making any changes.

Ant colony optimization(ACO) technique is utilized in truss size optimization with frequency constraints. Total weight of truss to be minimized is considered as the objective function and multiple natural frequencies are adopted as constraints. The modified traveling salesman problem(TSP) is adopted and total length of the TSP tour is interpreted as the weight of the structure. The present ACO-based design optimization procedure uses discrete design variables and the penalty function is introduced to enforce design constraints during optimization process. Three numerical examples are carried out to verify the capability of ACO in truss optimization with frequency constraints. From numerical results, the present ACO is a very effective way of finding optimum design of truss structures in free vibration. Finally, we provide the present numerical results as future reference solutions.
