  • The purpose of the thesis is to explore ways of improving the quality of urban life by analyzing the Luzinterruptus's work looking for a new perspective on the relationship between environmental color and society. The street artist Luzinterruptus was born in Spain, is a leader in the field of New Genre Public Art brush on a canvas of light in the night. They should seek the views of other common color system and color environments. The method of research is urban design, we consider the concept of the public good understanding, and New Genre Public Art. It also analyzes the environmental color of Luzinterruptus to take advantage of the phenomenology by David Katz color classification. The scope of the thesis is focused on the analysis of the works featured in their website and webzine. Then select a sculpture installation information is stated on the environmental color of their work. The role of environmental color in their work is not an aesthetic experience of harmonious urban landscape was seeking Public Art. The citizens of the area and the installation work themselves. Also it listed as demolition after the exhibition to realize the difference with other people and take advantage to environmental color. Therefore, they the contemporary agenda in many part of narrative takes in the garbage or disposables that you can easily look at our surroundings, In addition, citizens are directly experiencing the fantastic custom-made lights and colors and objects of the oversize as a potential recalls memories. Thus, the use of environmental color comfortable life there is horizontal participation and communication of the 'citizens' critical perspective of the 21st century cumulative cities.

  • Since the Framework Act on Resource Circulation was enacted in 2018, the government should establish a National Resource Circulation Master Plan every 10 years, which defines mid- to long-term policy goals and directions on the efficient use of resources, prevention of waste generation and recycling of waste. In addition, we must set mid- to long-term and stepwise targets for the final disposal rate, recycling rate (based on sorted recyclable materials and recycled products), and energy recovery rate of wastes, and relevant measures should be taken to achieve these targets. However, the current industrial waste (IW) statistics have limitations in setting these targets because the final disposal rate and recycling rate are calculated as the ratio of the recycling facility input to the IW generation. In this study, the material flow from the collection stage to the final disposal of industrial waste was analyzed based on the generation of 2016, and the actual recycling amount, actual incineration amount, final disposal amount and their rates were calculated. The effect on the recycling, incineration and final disposal rates was examined by changing the treatment method of nonhazardous wastes from the factory and construction and demolition wastes, which were put in landfills in 2016. In addition, the variation of the waste treatment charge was investigated according to the change of treatment methods. The results of this study are expected to be effectively used to establish the National Resource Circulation Master Plan and industrial waste management policy in the future in South Korea.

  • Underground environmental infrastructure and energy production facilities, which are recognized as avoidable facilities such as landfills, are emerging as an important social issue due to urbanization and economic growth. In order to safely construct a large-scale plant facility in the underground space, it is necessary to increase the utilization of the limited space layout and minimize unnecessary columns. In this study, the plant modularization method(Pipe Rack Module) was reviewed to solve the problems of work constraints, assembly and demolition, process system interconnection, and maintenance that occur when plant facilities are underground. In addition, plant module analysis was performed by applying various load conditions (earthquake load, device load, earth pressure load, etc.) to improve spatial layout usability and secure structure stability. Based on the analysis results under various boundary condition, the implications regarding the minimum installation interval and module arrangement (draft) of basic modules required for the construction of an underground combined plant were derived.

  • If a drama play is interested in recreating the play text on stage, the post-drama play aims at a drama that has been liberated from the play text. In this process, the boundaries created by drama theater are dismantled. Actors and audiences, fiction and reality, theater and non-theater, works and events, language and non-language are the names of typical boundaries. The demolition of these boundaries is an opportunity to restore the festival character of ancient Greek theater, which was forgotten by drama theater. This has led to the dismantling of language-centric and play-centricism, which has dominated the play since Aristotle, and has led to a new play. If language-centered, play-centricism has brought about the crisis of drama, the post-dramatic play dismisses them and finds ways to communicate with the audience as new cultural content. The method is found above all in the restoration of dramaturgy. This is because the post-drama plays are more dependent on theatricality than literature. The demilitarized nature of post-dramatic play with enhanced theatricality will be a stepping stone to popularization, and this shows the possibility of post-dramatic play as cultural contents.

  • Using industrial wastes and construction and demolition (C&D) wastes is potentially advantageous for concrete production in terms of sustainability improvement. In this paper, a sustainable Self-Compacting Concrete (SCC) made with industrial wastes and C&D wastes was proposed by considerably replacing natural counterparts with recycled coarse aggregates (RCAs) and supplementary cementitious materials (SCMs) (i.e., Fly ash (FA), ground granulated blast furnace slag (GGBS) and silica fume (SF)). A total of 12 SCC mixes with various RCAs and different combination SCMs were prepared, which comprise binary, ternary and quaternary mixes. The mechanical properties in terms of compressive strength and static elasticity modulus of recycled aggregates (RA-SCC) mixes were determined and analyzed. Microstructural study was implemented to analyze the reason of improvement on mechanical properties. By means of life cycle assessment (LCA) method, the environmental impacts of RA-SCC with various RCAs and SCMs were quantified, analyzed and compared in the system boundary of "cradle-to-gate". In addition, the comparison of LCA results with respect to mechanical properties was conducted. The results demonstrate that the addition of proposed combination SCMs leads to significant improvement in mechanical properties of quaternary RA-SCC mixes with FA, GGBS and SF. Furthermore, quaternary RA-SCC mixes emit lowest environmental burdens without compromising mechanical properties. Thus, using the combination of FA, GGBS and SF as cement substitution to manufacture RA-SCC significantly improves the sustainability of SCC by minimizing the depletion of cement and non-renewable natural resources.

  • This study presents a sustainable design method that optimizes the embodied energy of concrete beam based on the concept of sustainable development that effectively utilizes natural resource and energy within the range that our succeeding generation can afford to utilize. In order to get the flexural strength carrying the ultimate load, concrete beam sections are designed by optimization that consists of the embodied energy as a objective function and the requirements of design code as constrained conditions. The sustainable design can be used to minimize the embodied energy consumed in material production, construction, operation, demolition of the infrastructure. As a result of comparison of the cost and the embodied energy optimizations based on practical beam sections, it is shown that 20% embodied energy saving and 35% $CO_2$ emission saving are achieved by sacrificing 10% cost increase. The sustainable design method provides a new effective methodology that manages the strength design concept based on cost minimization together with economic feasibility and sustainability. In addition, the method is expected to be applied to more various structural design practices.

  • Citizen participation in local redevelopment has recently been regarded as essential, since progress in democracy and diversified public interests have contributed to more importance being placed on citizen participation in the implementation of public policies. While the importance of resident participation has been increasingly emphasized in principle, in reality more effort is still required in its application. We need to develop practical strategies of collecting community opinion in order to reflect it in public policy, if we are to achieve a resident and citizen-centered society. The purpose of this study is to develop an image map construction tool that can be applied to the "Maul-Mandulgi" projects as a visualized method to facilitate the exchange of opinions and work toward agreements. The tool is intended to assist public discussion by visualizing policies and plans and reducing the possibility of misunderstanding, so that residents can properly respond to the plans. Second, this study will verify the effectiveness of the tool in the application to local community workshops. The main research method is participant observation method and field study. Major findings are as follows, First, every resident who had participated in previous workshops gathered together, used the tool and represented their opinions unusually more than once. Each resident tried to make sure that other participants appropriately understood his or her opinion. The workshop finished when all participants agreed and produced a consensus. The workshop took much less time, which is in stark contrast to previous workshops in which it took significantly more time to collect opinions. Second, it proved that residents in the redevelopment area can strike a broad agreement by themselves on a method and direction for residential improvement. In previous workshops, conflicts between residents developed over the choice between the two methods, of local improvement and total demolition prior to multi-housing construction. In this study, opinions of residents were not limited to the two methods by finding a winwin solution. Third, the use of the tool kit for image map became efficient for inactive residents to develop their own opinions in regard to the direction and orientations of the residential improvement process. In addition, for those who have either no or a slight understanding of the residential improvement projects, the tool can provide access to information and knowledge. This study concludes that the developed tool for imaging of the redevelopment projection like a design game, rather than using forms of text and speech, can be a useful tool in collecting opinions and forming an agreed opinion for forthcoming residential improvement plans.

  • This study aimed at choosing the urban community parks such as D Kjin, Chungang, Dosan Park as the target place for this study, and at analyzing the damage level of the pavement surfaces focusing on the spaces and the materials. We devided the damage level within $1.5\times$1.5m grid int the grade from one to five points, and made use of the method of giving marks to get hold of the damage level of the pavement surfaces. Especially we took and analyze Duncan test for the spaces suffering severe damage. The result is as follows : 1. The damage of unenenness turned out to be a most excessive damage in the damage level according to the pavement materials in case of D kjin, and Chunggnag Park. Especially the concrete blocks proved to be the exessive damage in comparison with the other pavement materials, and the demolitional damage of the damage types to the most severe damage. The corner damage turned relatively out to be a heavy damage in case of Dosan Park in Seoul. 2. In the event of the damage level of pavement surfaces according to the spaces, the space which was made the more use of and which was the more concentrated, turned out to be the degree of the more excessive damage. 3. We took the Duncan test to verify the deference of the damage type between the spaces and the pavement materials of the target places for survey. The result of verification was that there was no difference of the damage type between the corner and block damage itself in case of the enterance area and the square of D kjin Park in Ch nju, and that the damage level of the pavement materials proved to be the more execssive damage than that of the spaces. The corner damage of Chungang Park in Hj ngju, showed the same result as D kjin Park in Ch nju and the uneveness didn't have any difference of damage type in all spaces. In case of Dosan in Seoul, the damage of crevice, demolition, and pumping didn't have any difference of damage type and the damage of the cross area was the most high. In conclusion, we proposed that we should get hold of whether the cause of pavement damage is caused by the defect of materials of by the construction problem including the foundation, or the unsuitableness of the method for using the pavement materials, and also that we should take a sensus of the user type and should decide a suitable design load and the necessary thickness of the pavement materials. In this study, not only we aimed at the external damage of the materials, but we tried to propose rather reasonable and developed construction method by studying the material experiment, the foundation state, and the type of using the spaces and materials, and by examining into the fundamental damaged cause.

  • Game technologies are now applied in various engineering areas such as the simulation of surgical operation or the implementation of a cyber model house. One of the essential and important technology in these applications is cutting of the 3D polygon model in real time. Real-time cutting technology is an essential technology needed to implement the simulation of a building demolition or a car assembly for training or educational purpose. Previous cutting method using the conventional BSP-Tree structure has some limitations in that they divide the whole world including the 3D model and its environment, only into two parts with respect to an infinite plane. In this paper, we show a technique cutting the 3D model in a finite extent in order to solve this problem. Specifically, we restricted the cut surface in a finite rectangular area and constructed the mesh for the divided surface. To show the usefulness of our partial cutting technique, an example of the dismantling process simulation of a nuclear reactor polygon model was illustrated.

  • The decommissioning of nuclear power plants is generally executed in five steps, including preparation, decontamination, cutting/demolition, waste disposal and environmental restoration. So, for efficient decommissioning of nuclear power plants, worker safety, effects compared to cost, minimization of waste, possibility of reuse, etc., shall be considered. Worker safety and measurement technology shall be secured to exert optimal efficiency of nuclear power plant decommissioning work, for which accurate measurement technology for systems and devices is necessary. Typical In-Situ methods for decommissioning of nuclear plants are CZT, Gamma Camera and ISOCS. This study used ISOCS, which can be applied during the decommissioning of a nuclear power plant site without collecting representative samples, to take measurements of the S/G Water Chamber. To validate the measurement values, Microshield and the GEANT4 code was used as the actual method were used for modeling, respectively. The comparison showed a difference of $1.0{\times}10^1Bq$, which indicates that it will be possible to reduce errors due to the influence of radiation in the natural environment and the precision of modeling. Based on the research results of this paper, accuracy and reliability of measurement values will be analyzed and the applicability of the direct measurement method during the decommissioning of NPPs will be assessed.
