BIM technology accomplished quantitative development being utilized in various disciplines. However, it is necessary to develop environment and requirement for qualitative improvement of BIM-based project in current transitional period of adopting BIM. The purpose of this study is to develop and apply of quality control requirement for improving the quality of BIM-based architectural design through case study. In particular, by focusing on BIM quality control and its relevant subjects, the minimum standards for BIM quality management are suggested. Also, BIM template is suggested to support the effective application of BIM-based architectural design.

Creeks, defined by creek's improvement law, have strong localities in the flow characteristics and environmental condition. During the recent ten-years, lots of flood damages have occurred rather in the creeks. However, quantity and stream design information are poor while the national-class and local-class streams have sufficient. This causes a problem on improving the safety from flood. This study focuses on assessment of practical applicability for design flood estimation models. For this, Rational formula, Clark's model and Nakayath synthetic unit hydrograph method are estimated by data of the creek comprehensive improvement plan report, etc.

There has been considerable interest recently in the topic of renewable energy. This is primarily due to concerns about environmental impacts. Moreover, fluctuating and rising oil prices, increases in demand, supply uncertainties and other factors have led to increased calls for alternative energy sources. Small hydropower, especially using water supply system, attracts high attentions because of relatively lower cost and smaller space requirements to construct the plant. Moreover. newly developed positive displacement turbine has high acceptability for the system. Therefore, the purpose of this study is focused on the examination of the performance characteristics and proposition of a optimum design method of the turbine for the improvement of the performance. The results show that newly proposed optimum design method for the turbine has high accuracy of performance prediction and good applicability for the performance improvement of the turbine.

In this paper, we propose an improvement plan to increase the learning effect and satisfaction through the PBL - related video design class. PBL To prepare for the Fourth Industrial Revolution era, we must acquire diverse knowledge and skills to discover problems and solve them creatively. Therefore, various learning methods are being studied, and one of them is PBL learning. PBL is a learner-centered education that explores problems that may arise from specific topics other than existing curriculum-based education methods and finds solutions to problems. In this study, two lectures on video design related to video contents and image contents were taught in PBL class, and PBL class problem was analyzed and the improvement plan was studied.

With the ever-increasing important of high-speed information in society as we move towards the 21 st century. Interior design and it's working condition has been changed a great deal included a sort of each special character and make a difference against the others. It used to be find a great poles asunder of worker's safety and project quality according to the environmental dimension of interior construction field as if they should be a pleasantness or poor condition. This research aimed to improvement of environmental construction field of interior with construction engineers and particular interior labors in 4 phases as : ⅠThe preparatory phase : -Secure a Budget, Environmental safety supervisor -Fix of Design quality, Construction period. -Choice of Construction method, Sub constructing Ⅱ. Starting work phase ; -Capacity , Safety of temporary power line. -Carriage, Stock of Material -Safety of Electronic tools, -Personal protector. Ⅲ. Working period ; -Ventilation, I illumination of working place. -Measurement of environmental working condition Ⅳ.Finish working phase ; -Analysis of measurement data. -Evaluation and making up for the weak point. -Keeping data.

This paper proposes the controller design for a stability improvement of an on-board battery charger. The system is comprised of a power factor correction (PFC) circuit and phase shift full-bridge DC-DC converter. The PFC circuit performs the control of the DC-link voltage and the input power factor. The DC-DC converter regulates the voltage and the current in the battery using the DC-link voltage. This paper proposes the design method of PI controller for the PFC circuit using a small signal model. The analysis and design of a type-three controller for the DC-DC converter is also presented. A simulation and experiment has been performed on the on-board battery charger and their results are presented to verify the validity of the proposed system.

Office workers at the architectural design office are under job stress for various reasons such as excessive working hours, friction with the site, and unpredictability of work. This can increase not only the negative image of office workers in the construction industry, but also the avoidance of young manpower in the future. This study investigated the specific purpose of each activity as a problem of job stress relief activities in the architectural design office, and the specific purpose and goal setting of each activity as a way to improve job stress relief activities.

A number of cities are committed to enhancing the barrier-free (BF) environments. However, no attempts have been made to examine the BF environment design concept by accounting for the universal BF components, which should be improved for providing both disabled people and non-disabled people with better BF environments. With this challenge in mind, this study determines the improvement priorities of BF components for beaches in the city of Busan by investigating the results of satisfaction survey, which was administered to disabled and non-disabled visitors. The modified importance-performance analysis (M-IPA) results show that "sanitation facilities" are the universal BF components having the highest improvement priority. The analysis results also indicate that "access facilities" have the second highest improvement priority for disabled people while "amenity facilities" have the second highest improvement priority for non-disabled people. It is highly expected that the suggested improvement priorities of BF components can be used for policy makers to develop more flexible plans when designing the BF beach.
