The purpose of this paper is to organize the issues regarding the necessary components of public design in order to provide an outlook of policy guidelines on urban design based on the concept of publicity and user participation. This paper includes an in-depth analysis of CABE in order to suggest communal notions and the values of public design that would enhance the quality of public design. Thus, it can be used as a reference when catalyzing public design regulations and policies in the future. It analyzes the design review and supportive tools for good decision-making of suggested in the CABE case in order to provide an integrated model of public design to overcome the difficulties presented by current approaches of public design. The unity of values, methods, subjects, issues, and places suggested in this paper is the key notion that emphasizes the importance of the integrated model of public design through the cooperation and communication between gents involved in public design process.

The Cultural Properties Protection Act enacted 1962 to encourge culture level of people by preserving and using cultural properties introduced Cultural Properties Change Permission System in 2000 in order to cope with rather targeted range towards the national designated cultural properties, and introduced the Guidelines for Permission Standard regarding Construction Activities within the Historical Cultural Environment Preservation Area (2006) to complement permission process and targets, Notification of Minor Changes around the National Designated Cultural Properties (2008), etc and continuously put efforts to improve further ever since. Nonetheless, while it showed decrease in the number of process of change permission per individual cases after 2007, it began to increase again since 2010, reaching 1,554 cases by 2014 - about 29% of the cases being rejected or under observation, people living surrounding of cultural properties still experience inconveniences. This study has been carried out by creating integrated DB with total 7,403 cases of permission status from 5 Subcommittees (Building / Historic Sites / Natural Heritage / Modern Cultural Heritage / Important Folk Culture) in Cultural Heritage Committee that are related with changing status for the past 5 years (2010-2014), and by further analyzing 4,364 cases amongst, that were reviewed within historical and cultural environment preservation area - analyzed applying types and the characteristics, reviewed the improvement plans of operation guidelines for the Committee and acts of minor changes towards surroundings of the national designated cultural properties that regulate the status changing permission targets by categorizing analysis results and deriving implications. I hope that this will complement to the operational guidelines for the Committee, along with minor changing activities around cultural properties in short term, and to secure basic data for systematic improvement plans ie., for delegated works range from city/county/districts through our research. Also hope to improve administrative efficiency by reforming permission systems for building activities in historic cultural environment conservation area, and reduce inconvenience people might experience, by minimizing socioeconomic expense needed for the review.

This study is the research of occupation distribution about citizen members of autonomy organization in Cheongju area. Investigation of autonomy organization members acting as local readers makes it possible to understand direction for community promotion. Result of this study sums up two type occupational categories. First, in urban area independently managers is above participation ratio in public affairs appeared. On the other hand, ratio of private organization, employee, and experts are low. In rural area, it shows the participation ratio of functional representatives and farmers highly. Second, with investigation of detailed occupation, most independent contractors and such as architecture, real-estate, whole and retail sales, restaurant, nursery, and private educational institute. And small number of insurance, news paper, car sales, gas station mangers participate in autonomy organization. Private organization consist of educational organization, social welfare corporate and district head council, as well as some teachers and farmers.

In Korea, the minimum separation distance between aboveground high-pressure natural gas pipeline and buildings is regulated by Korea gas safety (KGS) code. In this paper, The technical backgrounds for the revision of the KGS code related to the minimum separation distance was presented. A consequence-based approach was adopted to determine the minimum separation distance by a reasonable accident scenario, which was a jet fire caused by the rupture of one inch branch line attached the gas pipeline. Where, the higher thermal radiation flux threshold was selected for workers in industrial area than for people in non-industrial area, because the workers in industrial area were able to escape in a shorter time than the people in public. As result of consequence analysis for the accident scenario, we suggested the KGS code revision that the minimum separation distances between high-pressure natural gas pipeline installed above ground and buildings should be 30 meter in non-industrial area and 15 meter in industrial area. The revised code was accepted by the committee of the KGS code and now in effect.

This study was aimed to derive measures for maximizing ripple effect of construction of overseas industrial complexes on domestic economy. The induced coefficients were estimated for each step of development of industrial complexes by applying the raw data of ICAK and the input-output mode. As a result, for urban service, the fraction of labor costs was high, and for civil engineering, the fraction of profit & loss was high. However, the proportion of intermediate and profit & loss was high in Architecture. Consequently, compare to the same type of overseas constructions, larger effects were seen at urban service in terms of employment, at civil engineering and architecture in terms of business, and at national economy in terms of architecture. These results suggest that in order to maximize ripple effect of construction of overseas industrial complex on domestic economy, it will be needed to seek an order strategy including not only simply sell a land and but also building factories in the industrial complex.

In this study, we aim to develop a carbon-reducing concrete technology by incorporating biochar. Performance evaluation experiments were conducted on concrete mixtures containing biochar with insulating and carbon-capturing properties, which are essential for key infrastructure sectors such as construction and tunnels. Concrete mixtures were designed with different biochar incorporation rates of 0 %, 5 %, 10 %, 15 %, and 20 %, as w ell as w ater-to-binder ratios of 0.25, 0.30, 0.35, and 0.40. To assess the physical properties of each mixture, unit weight, total porosity, and permeability were measured, while mechanical properties were determined through the measurement of concrete compressive and flexural strengths. Key factors for enhancing the insulating effect of carbon-reducing concrete containing biochar were identified through regression analysis, indicating a close correlation among biochar incorporation rate, unit weight, concrete strength, and thermal conductivity. It is anticipated that it can be utilized as an insulating material to enhance thermal performance in northern regions with severe winter climates.

This study investigates the fundamental properties of the color concrete corresponding to the various types and contents of the coloring agent. For the properties of the fresh, the flow is gradually decreased corresponding to increasing of the coloring agent, and it is approached to the target flow on $3{\sim}6%$ of the adding amounts. The air content is increased in accordance with the increase of the coloring agent. For the properties of the hardened concrete, the compressive strength is increased about 9 and 12% in the case that $3{\sim}6%$ of red and yellow coloring agents is mixed. And they are decreased when white and black coloring agents. The chromaticity of red $(a^*)$ and yellow $(b^*)$ is appropriate at 6% of the adding amounts, and luminosity of the white and black is also favorable because of economy at 6%, so the formative article is manufactured successfully to aim in the result of this study.

The equation of end bearing capacity is applied differently depending on the type of pile, construction method, and load characteristics considering the construction standards. The bearing capacity equation of the design standard is presented in various ways according to the design conditions such as construction method and ground condition, etc. but, It does not reflect the ground strength according to the SPT-N value of weathered rock. This study analyzed the trend of allowable tip bearing capacity by pile diameter through about 480 dynamic loading tests conducted for the construction/quality management of piles for the last 6 years since 2015. The equation for the ultimate end bearing capacity per unit area according to the SPT-N value is presented. The proposed formula of ultimate end bearing capacity per unit area can be applied in the range of 15,000kN/m2 to 30,000kN/m2. The proposed formula, which complements the existing formula, enables pile design and construction/quality management.
