The purpose of this study is to use urban regeneration management types through classification and step-setting of physical types by administrative dong as the basis data for future urban management plans in local small and medium cities. The analysis was conducted on the physical density of each administrative dong by setting the data on urban and architecture provided by the government as three elements: buildings, lots, roads, etc. Through the system classified in this study, Mokpo City's 23 administrative districts were divided into nine management types and three management steps. Methodology can be utilized to establish areas of similar areas within the city and to use them as basic data for planning management. It is meaningful that it is possible to extract areas that need actual regeneration and maintenance through physical density analysis and plan suitable projects.

Modular construction is recognized as a construction method with various advantages, such as shortening the construction duration, achieving quality control through factory production, ease of maintenance, and reduced construction costs due to reduced weight of materials. However, despite efforts by the modular industry and government to activate modular construction, it has rarely been established in the domestic market. Currently, there are technical limitations to the modular construction fire resisting technology applied to general buildings. The lack of access to modular construction fire resistance regulation is considered a major factor. In this study, the current status and problems with modular construction fire resistance regulation, a significant hindrance factor, were considered to activate modular construction. This study is intended to present a direction for institutional improvement in modular construction fire resistance and a direction for research and development.

In an attempt to disseminate modernized Korean traditional housing (Hanok), a ten-year research project was initiated in 2010 by the Korean Government to reduce the construction cost, improve the facility performance, and automate the Hanok construction industry. To meet these objectives, various research areas, including public policies, planning methods, design standards, new building materials, construction standards, maintenance procedures, advanced project management tools, and integrated IT applications have been developed. In addition, comprehensive technologies developed were applied to the ten pilot Hanok buildings to validate the real-world performance as part of the research project. To further facilitate the digital transformation of the Hanok industry by using the research results, it is required to disseminate the developed technologies in an automated and standardized manner. In particular, it is crucial to systematize and manage the interoperability of various technical data and accumulated historical data for different business functions, especially within the highly fragmented industry. In this context, this paper proposes an ontology-based Hanok information dissemination platform to enable industry-wide automated knowledge and information sharing. The system architecture, standardized historical database, and advanced analytics based on ontology web language (OWL) for the Hanok industrialization platform are introduced.

Since 2013, the Ministry of Environment has been promoting the 'Green Stormwater Infrastructure (GSI) application project', a small-scale distributed stormwater management method, and supporting installation costs. So, the number of local governments that want to apply for 'GSI applied projects' is increasing every year. However, with the exception of Seoul, which introduced the 「Low Impact Development Prior Consultation System」, each local government has difficulties because there is no guideline or implement systems. Therefore, in this study, the application scope and priority setting of public buildings in Gyeongsangnam-do, the review of the GSI application effect in the pilot study area, and the establishment of an integrated implement system will be proposed as a result of the study.

Urban flood simulation plays a vital role in national flood early warning, prevention and mitigation. In recent studies on 2-dimensional flood modeling, the integrated run-off inundation model is gaining grounds due to its ability to perform in greater computational efficiency. The adaptive quadtree shallow water numerical technique used in this model implements the adaptive mesh refinement (AMR) in this simulation, a procedure in which the grid resolution is refined automatically following the flood flow. The method discounts the necessity to create a whole domain mesh over a complex catchment area, which is one of the most time-consuming steps in flood simulation. This research applies the dynamic grid refinement method in simulating the recent extreme flood events in Metro Manila, Philippines. The rainfall events utilized were during Typhoon Ketsana 2009, and Southwest monsoon surges in 2012 and 2013. In order to much more visualize the urban flooding that incorporates the flow within buildings and high-elevation areas, Digital Surface Model (DSM) resolution of 5m was used in representing the ground elevation. Results were calibrated through the flood point validation data and compared to the present flood hazard maps used for policy making by the national government agency. The accuracy and efficiency of the method provides a strong front in making it commendable to use for early warning and flood inundation analysis for future similar flood events.

Jogyeongdan is an altar built by the Korean Empire within the burial grounds of Sijomyo(始祖墓), the Jeonju Lee clan, as a part of their posthumous respecting project. This site adheres to strict rules and formalities that are comparable to those of the royal tombs of the Joseon Dynasty, with its altars and monument House demonstrating construction techniques that hold high value in architectural history. This study compares and analyzes construction-related records such as Uigwe, Statements, and Figure, along with their historical context. Through this effort, the study explores in detail the original form of Jogyeongdan at the time of its construction and subsequent transformations in later periods. Findings showed that the Figure was drawed by Chae Yongsin and was only a blueprint prior to the construction; it was modified during the actual construction process. A part of Jogyeongdan project was carried out by demolishing four government office buildings that were closed because of the Gabo Reform in order to secure wood and roof tiles, among other materials. Additionally, concluded the Jaesil was by relocated Deokryudang from Samryeyeokcham. Further, instances of distinctive terminology usage were found related to construction materials in the Jogyeongdan Uigwe, which were not used in another Uigwe. These terms were distinguished in detail according to the locations in which the materials were used.

This study aims to examine the cutting traces remaining on the bracket tie beams of Sungnyemun gate, identifying the tools employed during the late Goryeo to early Joseon periods by specific processes, and deliberating on the timber shaping techniques utilized in advanced architectural construction during the late Goryeo to early Joseon eras. Through the research, it was confirmed that in the production of Sungnyemun Gate's bracket tie beams during the 14th to 15th centuries, both the timber splitting and ripsawing methods were used in conjunction. Moreover, the wood finishing process revealed the use of a plane. It can be inferred that the characteristics of the plane used during that time were not significantly different from those observed in the later period of the Joseon dynasty. The ripsawing and plane finishing techniques were evident in various parts of the bracket tie beams of Sungnyemun gate across the reigns of king Taejo and Sejong, indicating that the techniques involving ripsaw and plane were already prevalent in the late Goryeo period. Consequently, it can be inferred that the ripsawing and plane finishing techniques might have been applied in the construction of prominent government buildings in Hanyang(Seoul), including Gyeongbokgung Palace, and in the residences of royalty and nobility after the establishment of the Joseon dynasty.

This study fundamentally is to develop standards and foundations for the establishment of traditional Korean gardens and aims to identify the mechanism and subsequent effect of fair gardens in American and Europe on the propagation and diffusion of the traditional Japanese garden. Fair gardens which were constructed between 1867 and 1939 were investigated to understand them and the ripple effect that they had on cultural dissemination. The results were as follows: Culturally, the Meiji government adopted Wagener's advice on the theme of display- including culture and handicraft-and the gardens with traditional buildings were perceived as one unit and then used as promotional tools as part of a national strategy. As a result, the stroll style garden in the Edo period and tea garden were recognized as the representative Japanese garden in America and Europe. Politically, the Japanese garden in the American context was adopted as examples of 'exotic beauty' and 'cultural heritage' which therefore allowed the Japanese government to achieve it's goal of encouraging friendly relations and the lessening of hostility towards them. Throughout the traditional Japanese garden, Japan with it's rich history presented an ideal - uniquely distinctive from the West. Using 'tradition' and 'nature' as keywords, the Japanese government set it's global image as 'perpetual tranquility'. Socioeconomically, the Japanese garden which was maintained after the fair, played a consistent role as a model of the Japanese culture. Many professionals from Japan who prepared the Japanese villages and gardens for the world fairs in America and Europe, remained in these countries following construction and it were these opportunities that allowed the Japanese garden to be integrated into local Western society.

An earthquake of magnitude 5.4 occurred on November 15, 2017 in Pohang, which caused the damage to buildings and facilities. The earthquake displaced more than 1,700 people. After the Pohang Earthquake, immediate emergency, such as the damage survey and running of shelters have been executed appropriately. However there have been issues with subsequent restoration measures, such as the provision of temporary housing and delivery of natural disaster allowance. As there was inadequate government advertisement about the natural disaster allowance, victims of the earthquake could not receive tangible help. In Japan on the other hand where earthquakes are frequent, post-earthquake restoration protocols are planned well in advance. For example, Japanese earthquake victims are provided with a guidebook outlining different types of government aids available for them so that they can rapidly access government aid. In this study, we refer to the case of Pohang earthquake to analyse the problems in the national earthquake restoration plans and propose how they can be improved by comparing it to Japanese post-earthquake case and a Korean equivalent should be developed, to aid Korean earthquake victims to return to their every life as soon as possible.

Developed nations have implemented various policies to reduce greenhouse gases since the 1997 Kyoto Protocol in order to minimize the effects of global warming. Korea should also reduce energy consumption in the industrial sector, and the transportation and building sectors in order to achieve its greenhouse gas reduction target of 37 percent compared to the Business As Usual levels. The government implements various laws and regulations for reducing energy consumption. To reduce energy consumption in the building sector, in particular, the Energy Conservation Design Standards are enforced according to the 'Enforcement Support for Green Building Construction'. The amount of electricity used to maintain room temperature at $28^{\circ}C$ in these buildings have a 30% reduction (measured on the walls and rooftop) in power usage compared to buildings not required to meet these standards. Although the effect of these energy savings on landscaping is proven, this demonstration is not effective for energy saving since it is not a suitable method for the 'Energy Saving Design Standards of Buildings'. For landscaping to be effective as far as a component of energy reduction, the perfusion rate of the building should be calculated based on the thermal conductivity of the component materials for the energy saving designs with respect to the basis of Article 14 of the Green Building Act. Therefore, the purpose of this study is to ensure that the planting-based mats currently being widely used in the landscape industry can have insulating performance suitable for the 'Energy Saving Design Standards' of Buildings according to the 'Enable Green Building Construction Methods'.
