Detached residential housing areas are located in the west part of Pangyo City. Seven areas of them are designated for the displaced residents from their original homes by the city development, in which commercial use on the first floor is permitted. The District Plan for the areas were establishes, and one of its main goals is to secure privately owned public spaces (POPS). This research conducted a post enumeration survey on the POPS on the blocks in the seven areas, which blocks contain inner corridors between two rows of housing units. Analytical review of the survey result reveals that (1) POPS facing roads are mainly being used as parking lots or expansion-spaces for the commercial use on the first floor, (2) inner POPS forming corridors are being neglected and otherwise being used as storage areas or outdoor sub-kitchen spaces, and (3) no consideration has been taken for the continuity of the sloped corridors. Regardless of a few good practices in terms of air circulation and lighting, the POPS in the blocks prove to be limited in following the plan's original design intentions and principles.

In general, auto parts production assembly line is assembled and produced by automatic mounting by an automated robot. In such a production site, quality problems such as misalignment of parts (doors, trunks, roofs, etc.) to be assembled with the vehicle body or collision between assembly robots and components are often caused. In order to solve such a problem, the quality of parts is manually inspected by using mechanical jig devices outside the automated production line. Automotive inspection technology is the most commonly used field of vision, which includes surface inspection such as mounting hole spacing and defect detection, body panel dents and bends. It is used for guiding, providing location information to the robot controller to adjust the robot's path to improve process productivity and manufacturing flexibility. The most difficult weighing and measuring technology is to calibrate the surface analysis and position and characteristics between parts by storing images of the part to be measured that enters the camera's field of view mounted on the side or top of the part. The problem of the machine vision device applied to the automobile production line is that the lighting conditions inside the factory are severely changed due to various weather changes such as morning-evening, rainy days and sunny days through the exterior window of the assembly production plant. In addition, since the material of the vehicle body parts is a steel sheet, the reflection of light is very severe, which causes a problem in that the quality of the captured image is greatly changed even with a small light change. In this study, the distance between the car body and the door part and the door are acquired by the measuring device combining the laser slit light source and the LED pattern light source. The result is transferred to the joint robot for assembling parts at the optimum position between parts, and the assembly is done at the optimal position by changing the angle and step.

As life, once immersed in labor, changes with values and lifestyles, individuals consume or participate in culture and arts for learning, meeting of intellectual needs, pleasure, and exchange. As culture and art spaces have increased in recent times, these spaces have been transformed into places to create, view and exchange culture and art, and to consume cultural goods. Culture and art spaces have created and developed new genres and technologies that give viewers the opportunity to communicate and participate, allowing them to understand and accumulate works of media. A media façade thus gives a preference to places for visitors by giving an impression over a short period of time in culture and art spaces that are not areas for exhibitions and performances, and providing an opportunity to more easily approach and understand works and culture and art spaces. A media façade is a type of medium that imparts aesthetics and information by installing LED lighting on the exterior wall of a building for the realization of media functions. In order to analyze the effect of the media façade on preferences for culture and art spaces, a research model was established with media façade characteristics as independent variables and preferences for culture and art spaces as dependent variables. As a result, media façade design and media features influenced satisfaction, while the media characteristics of the media façade influenced recommendation and revisiting, suggesting that many changes will take place in culture and art spaces.
