The purpose of this research aims to retrieve the communication which is the essential publicness in the built environment design and the self-management which is the original value in terms of sociology. To examine this, the way in which the characters of the design of the publicness have been changed will be concentrated on in the public area since 1980s, Particularly, this research has been focused on the Second modernity design which is against the aggressive utopia - oriented modernization and Reflexive Modernization which has been mentioned by Anthony Giddens, Ulich Beck, and especially Scott Lash. Also, to understand Reflexive Modernization, the realism art in the view point of the objective recognition of modernity and identity emphasized by Scott Lash will be examined. Through the analysis of the Nene Sachlichkeit which is a part of the realism art, how the reflection of the design can be the function of the design will be addressed and some examples will be analyzed in terms of communications and self-education in the design of the publicness. Thus, Contemporary Built Environment Design features are categorized into universality, objectivity, and rationality; it reaches that the past Neue Sachlichkeit meets the spirit of art; it concludes that the efforts of the reflection of the modernity, intensity and development in design are the challenges for the purpose of the design of the publicness.

For the safe handling of Propionic Anhydride being used in various ways in the chemical industry, the flash point and the autoignition temperature(AIT) of Propionic Anhydride was experimented. And, the lower explosion limit of propionic anhydride was calculated by using the lower flash point obtained in the experiment. The flash points of propionic anhydride by using the Setaflash and Pensky-Martens closed-cup testers measured $60^{\circ}C$ and $61^{\circ}C$, respectively. The flash points of propionic anhydride by using the Tag and Cleveland open cup testers are measured $67^{\circ}C$ and $73^{\circ}C$. The AIT of propionic anhydride by ASTM 659E tester was measured as $280^{\circ}C$. The lower explosion limit by the measured flash point $60^{\circ}C$ was calculated as 1.37 Vol.%. It was possible to predict lower explosion limit by using the experimental flash point or flash point in the literature.

A laser-vision-based height measurement system is developed and implemented for the inspection of two-step variable valve lift module assemblies. The proposed laser-vision sensor module is designed based on the principle of laser triangulation. This paper summarizes the work on 3D point cloud data collection and height difference measurements. The configuration of the measurement system and the proposed height measurement algorithm are described and analyzed in detail. Additional measurement experiments on the height differences of valves and lash adjusters of a two-step variable valve lift module were implemented repeatedly to evaluate the accuracy and repeatability of the proposed measurement system. Experimental results show that the proposed laser-vision-based height measurement system achieves high accuracy, repeatability, and stabilization for the inspection of two-step variable valve lift module assemblies.
