Recently, due to the child-friendly city project being conducted by UNICEF, the movement to create a child-friendly cities has been actively promoted by the South Korean government. However, due to the lack of specific physical plans to improve the basic rights of children in the city, the project has been mainly implemented for educational and institutional projects. In this study, we investigated the activities of children and parents living in elementary school neighborhoods. Based on our investigation, we attempted to generate the desired results that can be referred to by physical planners looking to make changes to school neighborhoods by comparing and analyzing children and parents' activity range and life patterns in the neighborhood. The GPS and traffic log surveys were conducted as the primary research methods. The results of this study are as follows: First, both children and parents are most likely to walk in their neighborhoods. In addition, the use of private cars and school vehicles was high, but the use of public transportation was low. Second, the longer parents and children stayed together, the wider the range of their activities. Third, children who spent a lot of time with parents were more likely to have diverse life patterns than children who did not spend a lot of time with parents. Fourth, parents who live in elementary school neighborhoods frequently used commercial facilities and cultural centers around the school. Therefore, it is important to construct facilities around the school for parent-use.

Modular construction projects offer advantageous over conventional construction projects in the area of quality control through factory production. However, as clear standards and definitions for quality control activities have yet to be not established, it is difficult to judge the appropriateness of the scale of quality control costs, and it is also difficult to classify quality control activities by process stage. Therefore, in this study, a method for classifying quality management activities based on activity standards was presented, in addition to a method for classifying quality costs according to the PAF standards to check how effective the costs and activities are for quality control in the future. The findings of this study can be used to define the quality management activities for each stage of the modular construction project in the future, and to develop a database of evidence to determine the appropriateness of cost distribution accordingly.

In recent, as rediscovery of the modern value is developed through the support by the government and the reinterpretation of the traditional culture, a Korean-style house(Hanok) also becomes an object of interest. Among these various viewpoints to see the Korean-style house, the necessity of a new spatial design approach to contain the types and functions of the architectural space of the Hanok appropriate to the modern society is raised which is not a passive approach to preserve the existing cultural assets. Out of the methods of the new spatial design of the Hanok which reflect the paradigm of the times, this study has the purpose to make an approach from the viewpoint of 'Restoration design'. As the 21 st century started, the recycle design whose active discussion and performance is made largely by Europe and Japan can be called a design method in the hardware part which enables continuous adaptive use of a building by applying a new use purpose and method to a building which doesn't use the recycle design or has low efficiency. In that meaning, it can be considered to be a very important architectural activity historically, archltecturally and spatially. Based on the methodological characteristics of the recycle design, this study largely divides the types of recycle into coherent recycle and imagery recycle and dedto s detailed methods of space, consinto ion and material and wardrobe used for each case to analyze the methods of concrete recycle design through the methodological analysis of recycle cases of the existing modern buildings. For the objects of recycle cases of the Hanok made recently based on the design methods acquired here, it was examined how the architectural and spatial characteristics of the Hanok can be reconsinto ed through what kinrecycmethods. The approach of the recycle design is considered to be a cornerstone to show a new architectural and spatial value in the viewpoint of the Hanok existence in modern times.

The high school credit system is a system in which students select complete various subjects, depending on their career, and graduate when their accumulated credit reaches the standard. It is expected that the high school credit system, which guarantees the individual's right of choice, will bring an educational effect that can respond to the student's career aptitude. However, it is expected that problems in the aspect of school life, such as the weakening of class belongingness or difficulty of securing a stable base venue within the school building would be accompanied. This research analyzed students' usage condition depending on the living base space environment feature in schools that are implementing moving-selective class in the aspect of activity domain formation and contemplated the venue evaluation. The purpose is to provide the basic data of an architectural plan of a stable living base space within the school building through this. 'Living base center type' and 'living base dispersion type' school buildings among Japanese integral department high schools were used as the target to analyze the usage condition in the aspect of domain formation. As a result, a conclusion was deducted that student's securement of territory consciousness about the base space and venue construction for the community of various studying groups affects life satisfaction.

In modern society, indoor activities time is increasing due to industrial development. Interest in indoor air quality is increasing as indoor activity time increases. The main causes of indoor air pollution are formaldehyde which a chemical cause, and fungi which a biological cause. Phytoncide effectively reduces Formaldehyde and Fungi. Charcoal which possess porous-structure has a good absorbance of pollutants. In this study, the authors manufactured functional cement matrix using by phytoncide and charcoal to remove formaldehyde and fungi. In this study, Functional cement matrix reduced formaldehyde and Fungi and effectively improve indoor air quality.

Recently, the amounts of dredge sea soil in south Korea have been increasing because of various maintenance works at harbors and rivers. Dredged sea soil contains various contaminants. Hence, prior to recycling the dredged sea soil, the various contaminants should be removed to prevent a secondary contamination due to the leaching of hazardous chemicals. Pretreated dredged sea soil can be buried under the ground or used for land reclamation. In this study, however, pretreated dredged sea soil was used to investigate the level of pozzolanic activity. The properties of pretreated dredged sea soil were investigated, the method for heat treatment was determined, and the compressive strength of mortar using dredged sea soil was examined. According to the XRF result, the main components of dredged sea soil were $SiO_2$ of over 55%, and $Al_2O_3$ and $SO_3$ of some amounts. Results from XRD and TG/DTA showed that pretreated dredged sea soil can be used as a pozzolanic material. When dredged sea soil was thermally treated for 90 min at $550^{\circ}C$, a compressive strength result was similar to that of control mortar.

At the completion of the construction, various finishing processes are concentrated. This imposes a burden on the on-site manager and imposes on experience based quality control, thereby causing deviations in the quality of construction depending on supervisor or worker's individual competence. In addition, the information related to quality control is frequently scattered in various types of documents such as specifications and drawings, and checkpoints are frequently omitted. It is necessary to provide a tool that can effectively provide the practitioner before or during the inspection work by systematically storing the information related to the defect prevention and linking them in a mutually referential state. This paper proposes an quality inspection support model that can systematically store necessary information on activity or room basis for the quality check of the apartment house finishing work. Establish a defect prevention information base and a information nexus by linking specifications, design standards, checklists, regulations, defect cases, and drawings to the finishing process and the rooms. Based on this, information registration and search interface are presented. It can contribute to securing a certain level of construction quality or more by suggesting a frame that can be utilized by linking various defects prevention information with the focus on closing activity and room.

Although hazard identification is one of the most important steps of safety management process, numerous hazards remain unidentified in the construction workplace due to the dynamic environment of the construction site and the lack of available resource for visual inspection. To this end, our previous study proposed the collective sensing approach for safety hazard identification and showed the feasibility of identifying hazards by capturing collective abnormalities in workers' walking patterns. However, workers generally performed different activities during the construction task in the workplace. Thereby, an additional process that can identify the worker's walking activity is necessary to utilize the proposed hazard identification approach in real world settings. In this context, this study investigated the feasibility of identifying walking activities during construction task using Wearable Inertial Measurement Units (WIMU) attached to the worker's ankle. This study simulated the indoor masonry work for data collection and investigated the classification performance with three different machine learning algorithms (i.e., Decision Tree, Neural Network, and Support Vector Machine). The analysis results showed the feasibility of identifying worker's activities including walking activity using an ankle-attached WIMU. Moreover, the finding of this study will help to enhance the performance of activity recognition and hazard identification in construction.

Enhancing utilization of buildings is gaining in importance in response to a challenging economy; thus, there is a need for a method that analyzes space, user, and user activity in an integrated way to provide project stakeholders with utilization information to support their decision-making about buildings. Conventional methods, such as architectural programming and post-occupancy evaluation, lack a formal relationship between user activity and other information, and therefore, are coarse-grained. This relationship has been formalized by two relatively new methods that provide fine-grained utilization information: workplace planning and space-use analysis. We characterize these two methods with focuses on their usage in different phases (i.e., planning, design, occupancy), required information that needs to be gathered, and the achievement and limitations in terms of three criteria, i.e., consistency, efficiency, and transparency. This characterization would not only help project stakeholders select and use a method that best meets their purposes for enhancing utilization of their buildings, but also provide researchers with promising research topics regarding enhancing utilization of buildings.
