The goal of this study was to efficiently analyze the relationships of the number of thefts with related factors, considering the spatial patterns of theft crimes. Theft crime data for a 5-year period (2009-2013) were collected from Haeundae Police Station. A logarithmic transformation was performed to ensure an effective statistical analysis and the number of theft crimes was used as the dependent variable. Related factors were selected through a literature review and divided into social, environmental, and defensive factors. Seven factors, were selected as independent variables: the numbers of foreigners, aged persons, single households, companies, entertainment venues, community security centers, and CCTV (Closed-Circuit Television) systems. OLS (Ordinary Least Squares) and GWR (Geographically Weighted Regression) were used to analyze the relationship between the dependent variable and independent variables. In the GWR results, each independent variable had regression coefficients that differed by location over the study area. The GWR model calculated local values for, and could explain the relationships between, variables more efficiently than the OLS model. Additionally, the adjusted R square value of the GWR model was 10% higher than that of the OLS model, and the GWR model produced a AICc (Corrected Akaike Information Criterion) value that was lower by 230, as well as lower Moran's I values. From these results, it was concluded that the GWR model was more robust in explaining the relationship between the number of thefts and the factors related to theft crime.

After the Korean war, two major attempts were made to reconstruct Gwanghwamun Gate as an important part of Korea's lost cultural heritage. In December 2006, the Korean government replaced the concrete gate with a wooden one, yet traces of the attempts made in the 1960s to transform Gwanghwamun Gate and the main road remain to this day. At the time, the Third Republic of Korea, sought to legitimize itself in the name of modernity, and went on to modernize the architecture and urban landscape of Seoul. The location and design selected for the rebuilt Gwanghwamun illustrated the symbolic relationship between historic heritage and urban development. The reconstruction of the gate began as part of the Third Republic's project to restore the Central Administration Building and culminated in the transformation of the main road in front of the gate. By reconstructing the traditional gate using concrete, the military government intended to convey the message that we could inherit our proud tradition using modern materials, and that we should actively adopt the new technologies of the modern era. This study begins with the premise that the Gwanghwamun reconstruction project of 1968 represents the application of new technological thinking to Korea's architectural style, and has two objectives. The first is to summarize the reconstruction process and method using the records and drawings from the 1968 project, which was then under the leadership of architect Kang Bong-jin. The second is to analyze the characteristics of the architectural style and structure of the reconstructed Gwanghwamun so as to reinterpret the relationship between Korean tradition and modern technology.

This paper examines how South Korean government regulators and environmental scientists endeavored to improve the environmental quality of Seoul in preparation for the Olympic Games in 1988. When Seoul was nominated as a host city of the Summer Games in 1981, it was suffering from severe environmental pollution. The municipal government of Seoul and the Ministry of Environment initiated a series of pollution survey projects, which were followed by relevant regulatory procedures. One of the outcomes of these projects was the beginning of odor pollution regulation that used the Environmental Official Testing Method. Although the Pollution Prevention Act of 1963 made odor pollution such as unpleasant order, stench, and stink subject to environmental regulation, proper administrative procedures to reduce odor pollution were not in place until the 1980s. In order to reduce odor pollution in urban areas, governmental officers and environmental scientists tried to regulate odor-causing chemicals from factories. In June 1988, however, severe odor pollution was detected not from factories but from unregulated areas in Seoul, such as the waterside parks of the Han river, the downtown, and the marketplaces. The local regulators and scientists were concerned that the odor pollution could make a "wrong" impression on foreign athletes and visitors about the degree of "modernity" of Korea. This paper shows that the 1988 Summer Olympics was a transition point in the early history of odor regulation in South Korea, when the scope of odor regulation could be expanded.

In this article, I examine the transformation of the Iksan Royal Palace into a temple. And it was considered to mean a change in the way Iksan was managed by Baekje. The Iksan Royal Palace was converted into a temple between the establishment of Mireuksa Temple and Stone Pagoda. As a result, the transfer of the capital to Iksan was not achieved, and Iksan was transformed into a temple-centered city. In connection with this, the need to re-establishment the urban system in Sabi was increased, as it suffered a great flood in the Muwang era. As a result, the scope of the royal palace was expanded, the secondary palace was built, and the urban district was expanded throughout the capital city. It is presumed that King Mu gave a divine nature to Iksan and discriminated against Sabi. Accordingly, it is believed that the King Mu or King Uija stopped developing the city in Iksan and focused on the rearrangement of Sabi.

This study investigated the chemical properties of Organic Soil Amendments (OSAs) made from organic waste. It also assessed the effectiveness of using these OSAs in the soil layer of Green Infrastructure (GI) to reduce stormwater runoff and non-point source pollutants. The goal was to improve the national environmental value through resource recycling and contribute to the circular economy transformation and carbon neutrality of urban GI. The OSAs used in this study consisted of spent coffee grounds and food waste compost. They were found to be nutrient-rich and stable as artificial soils, indicating their potential use in the soil layer of GI facilities. Applying OSAs to bio-retention cells and permeable pavement resulted in a reduction of approximately 11-17% in stormwater runoff and a decrease of about 16-18% in Total Phosphorus (TP) discharge in the target area. Increasing the proportion of food waste compost in the OSAs had a positive impact on reducing stormwater runoff and pollutant emissions. This study highlights the importance of utilizing recycled resources and can serve as a foundation for future research, such as establishing parameters for assessing the effectiveness of GI facilities through experiments. To enable more accurate analysis, it is recommended to conduct studies that consider both the chemical and biological aspects of substance transfer in OSAs.

Even at this point in the era of digital transformation, we are still facing many problems in the safety sector that cannot prevent the occurrence or spread of human casualties. When you are in an unexpected emergency, it is often difficult to respond only with human physical ability. Human casualties continue to occur at construction sites, manufacturing plants, and multi-use facilities used by many people in everyday life. If you encounter a situation where normal judgment is impossible in the event of an emergency at a life site where there are still many safety blind spots, it is difficult to cope with the existing manual guidance method. New variable guidance technology, which combines artificial intelligence and digital twin, can make it possible to prevent casualties by processing large amounts of data needed to derive appropriate countermeasures in real time beyond identifying what safety accidents occurred in unexpected crisis situations. When a simple control method that divides and monitors several CCTVs is digitally converted and combined with artificial intelligence and 3D digital twin control technology, intelligence augmentation (IA) effect can be achieved that strengthens the safety decision-making ability required in real time. With the enforcement of the Serious Disaster Enterprise Punishment Act, the importance of distributing a smart location guidance system that urgently solves the decision-making delay that occurs in safety accidents at various industrial sites and strengthens the real-time decision-making ability of field workers and managers is highlighted. The smart location guidance system that combines artificial intelligence and digital twin consists of AIoT HW equipment, wireless communication NW equipment, and intelligent SW platform. The intelligent SW platform consists of Builder that supports digital twin modeling, Watch that meets real-time control based on synchronization between real objects and digital twin models, and Simulator that supports the development and verification of various safety management scenarios using intelligent agents. The smart location guidance system provides on-site monitoring using IoT equipment, CCTV-linked intelligent image analysis, intelligent operating procedures that support workflow modeling to immediately reflect the needs of the site, situational location guidance, and digital twin virtual fencing access control technology. This paper examines the limitations of traditional fixed passive guidance methods, analyzes global technology development trends to overcome them, identifies the digital transformation properties required to switch to intelligent variable smart location guidance methods, explains the characteristics and components of AI-based public facility smart fire safety integrated system (ISFS).

Hanok is Korea's traditional housing. From the 1970s, the vast majority of citizens in urban areas have not lived in Hanok housing but an apartment. Consequently, many people no longer familiar with the experience of living in traditional Hanok. People who live in the environment of residential apartments eargle like new residential and pursue eco-friendly homes, health homes, espacially among the hanok was reassure potential. There have been many debate how Hanok housing can become more sustainable, yet keep characteristics of its identity. The purpose of this study is to examine the process by which traditional Hanoks and modern architecture can influence each other, how the popularization of modern homes was formed and this relationship with the new less popular Hanoks. Finally, We will exmine how old Hanok can be renovated into new, modern Hanoks. The subject areas are Seoul, Jeonju, and Chongju in early twentieth century; by discussing with upper-class Hanok to improve the general standard of most traditional Hanok.
