The purposes of this study were (a) to compare the level of sense of community and community activity of the mixed-use residential buildings' residents with the expected residents for the mixed-use residential building, (b) and to investigate the degree of their needs of social interaction. For the survey the questionnaire from 176 residents of mixes-use residential building in Seoul, and 67 expected residents in Bundang Newtown are used. The analytical methods adopted in this study were frequency, percentage, chi-square test and t-test. It was found that the level of sense of community and the community activities of the mixed-use residential building' residents were higher than those of the expected residents. Their residents reported higher degree of participation on community activities than the expected residents. It was also found that the common space in their residential area promoted the residents' sense of community and community activity.

Recently, the regulation about HEE(horizontally installed emergency exit) established at upper 4story in apartment houses was introduced by revising enforcement degree of Building Act. HEE is a facility for egress to lower story through floor breach and ladder system so that it gives a useful evaquation way directly to an individual household in apartment when they failed to evacuate through the entrance door. HEE may offer an opportunity to optain two way egress path ways instead of evacuation space at balcony and through path way to adjacent household in building and that might be an big strengh. but it needs to guarantee for against the crime, getting detailed reviews for being security and supplementation of fire test methods.

We performed calculations combining optimization technologies and Computational Fluid Dynamics (CFD) aimed at reducing wind forces and mitigating wind environments (local strong winds) around buildings. However, the Reynolds Averaged Navier-stokes Simulation (RANS), which seems somewhat inaccurate, needs to be used to create a realistic CFD optimization tool. Therefore, in this study we explored the possibilities of optimizing calculations using RANS. We were able to demonstrate that building configurations advantageous to wind forces could be predicted even with RANS. We also demonstrated that building layouts was more effective than building configurations in mitigating local strong winds around tall buildings. Additionally, we used the Convolutional Neural Network (CNN) as an airflow prediction method alternative to CFD in order to increase the speed of optimization calculations, and validated its prediction accuracy.

In order to respond to changes in the industrial environment such as the 4th industrial revolution, university education also needs active educational innovation efforts. This study proposed a construction construction hybrid curriculum that can actively utilize online education in the direction of educational innovation in domestic universities. The hybrid curriculum was based on online learning through lecture videos used in team-based learning. The hybrid curriculum additionally allows learners to choose their learning methods. In a hybrid class, learners can choose the class participation method they want from offline classroom or online real-time. Hybrid classes are considered to strengthen learners' options and take a step forward in learner-centered education.

Unlike other educational spaces in school facilities, restrooms have remained unpleasant spaces without reflecting the change in social awareness and students' lifestyle. In the process of the 'School Restroom Environment Remodeling Project in Seoul' by means of "user participatory design method", this study aimed to suggest a design of the school restroom environment responding to the different needs of actual users, who are students and school staffs. By surveying them, it was revealed that they have a variety of respective behavioral patterns and spatial needs according to their status, gender, age and working period. Implications of this study are as follows; First, it is necessary to establish a separate restroom facility standards that respond to the characteristics of elementary school students. Second, there should be an expansive approach to widely accommodate with the users' needs that were found out through 'user participation', more than just repairing pre-existing space. Third, it needs to have critical review of the maintenance and operation system itself as well as the improvement of the school restroom environment.

The quality of apartment houses has been gradually upgraded. However the changes in demographic composition of residents such as seniors, disabled persons, and etc. have not been considered in the process of planning. If apartment houses are designed on the base of the concept of universal design, their residents could live as long as they want to live in. This study evaluates the Korean standard-sized apartment housing units and the common spaces of those apartment buildings, and it's outdoor environments from the perspective of universal design. The observation and measuring was conducted with the questionnaire survey with 100 residents living in those housing units. 60 items were designed for evaluating them in relation to the principles of universal design. The results are as follows : 1) In general, the principles of universal design were relatively applied to the apartment houses. However their application needs to be broadened. 2) The number of parking lots needs to be increased and the width of individual parking lot to be increased. Also, the location of gazebo and senior center needs to be placed in easily accessible areas. 3) The shape, color, finishes of the ramp and the entrance area of the apartment building and housing unit should be made more homelike. Also, the entrance area of apartment building and housing unit needs to be made large enough for residents themselves and meeting with neighbors. 4) Among all of the rooms in a housing unit, bathroom should be improved immediately. Also, the width of doors should be at least 80cm wide and the floor should be made even.

Most of buildings have been deteriorated with time-elapse by reflection of the building location, material, environmental circumstances and so on. The performance would go down and be demolished if anything could not be done after constructed. The maintenance should be required to preserve a decent living condition or improve a inferior condition by various plans and practices. The maintenance plan needs various data such as a repair scope, a repair time, a forecasted cost, a plan of management and so forth. Among the above required data for planning the maintenance, the deterioration characteristics of the building components would be first analyzed. The deterioration pattern would be a key role to affect and make a maintenance plan. In this paper, it aimed at classifying the deterioration patterns of building components. A deterioration pattern would be analyzed between the cumulative repair cost and time-elapse and modeled with these relations. A deterioration patterns are classified into 4 types-a accelerated type, a straight type, a temporary type and a slowly type. As a result of this research, a accelerated type includes window, window frame, general paintings, general water proofing in building components. A straight type includes the lacquer paintings, furnishings in building components and water supply pipe, boiler, sanitaries in mechanical facilities and lighting in electric facilities. Based on these research results, further study should be conducted to include any other components and an estimating model.

Current supervision systems have been changed by the demands of social, physical and institutional environment, and have a role of preventing safety accident and in improving the construct ability through the analysis of issues in quality, time, construction, safety, and environmental management. The public sector "Construction Technology Management Act", a general and private sector "Building Act" and "Certified Architects Act", the residential building "Housing Act" are dealt with supervision systems, respectively, but private small building construction is excluded from the discussion of the main targets because of their relatively small scale and the lack of social interests, Thus, this study focused on the small buildings for improving the non-resident supervision systems. Survey results revealed that the non-resident supervisor needs to be selected not by clients but by officers in order to obtain its publicity. Based on the proper selection and execution of the supervision system suggested in this study, the potential effects can be summarized as 1) recovering of publicity, 2) correcting abnormal practice, and 3) realizing design intention for increasing the public value of buildings. In addition, findings in this study will be effective to amend current non-resident supervision systems for improving the quality of buildings and communities as well as for adopting the environmental-friendly energy-efficient smart building technologies.
