Evaluating landslide hazards using RCP 4.5 and 8.5 scenarios

Recently, extreme meteorological events have occurred frequently owing to climate change and its influence. Impacts of concentrated precipitation events include the damage caused by landslides. Many areas in Gangwondo (Korea) are located at high elevation and have large elevation differences; these areas are thus at high risk of landslides. The purpose of this study was to evaluate the landslide hazard of the province using representative concentration pathways (RCP) scenarios 4.5 and 8.5 and to compare results. This study produced an optimal landslide model for the province through analysis of variables and points of landslide origin. Estimates indicate that the landslide hazard area will increase to 154xa0km2. The RCP 8.5 scenario showed a larger (by about 59xa0km2) landslide hazard area than the RCP 4.5 scenario. The uncertainty of climate change scenarios was also explored using statistical values of each scenario period. An overlay analysis (overlay of landslide hazard areas and land cover map) showed that 40.6xa0% of farmlands would be susceptible to landslides in 2070–2099 (RCP 8.5). Additionally, damage to the alpine agriculture due to landslides was also identified as a critical area. In the RCP 8.5 scenario, the land-use types that occupy more than 20xa0% of the landslide hazard area are transportation, recreational facilities, and vinyl house for farming. This suggests that casualties from landslides will increase in future. It also highlights a lack of policies to manage development. Therefore, the local government of Gangwondo should consider landslide hazard areas when planning future land uses.

Stakeholder Subjectives Toward Ecotourism Development using Q methodology: The Case of Maha Ecotourism Site in Pyeongchang, Korea

Ecotourism needs ecological sensitivity and respect for the ecological culture of local residents. From this perspective, listening to the opinion of local residents, collaborating with the local residents in conjunction with an appropriate governance structure, is of prime importance in ecotourism. However, many ecotourism sites have numerous problems because of conflicts among stakeholders such as local government and local residents. This study investigates the conflicts and the stakeholders’ subjectives in the case of Maha ecotourism site in Pyeongchang-gun, the site of the 2018 Winter Olympic games. Before the analysis, the conflicts seem to be caused by the different attitudes of government officials and local residents’ representatives. From the analysis of subjectives, the difference in attitudes is caused by generation gaps. Young people show relatively uniform attitudes, where different occupation sectors exert little influence. It means that conflicts can be decreased if more opportunities for council participation are allowed. Young people have few consideration about ecology and tradition. The ecological and traditional lessons of the older generation are needed for young people. This study shows that conflicts between development and conservation are caused by the different attitudes represented in different generation, and hence plans for harmonizing different generation should be considered.

The impacts of weather on tourist satisfaction and revisit intention: a study of South Korean domestic tourism

ABSTRACT This study explores the impacts of weather on tourist satisfaction and intention to revisit sites utilizing a survey of 1736 domestic tourists in South Korea. This study adds tourists’ perceived quality of weather to a path model that anticipates revisit intention and was originally based on the perceived quality of physical attributes and service, as well as tourist satisfaction. The results of this study show that the perceived quality of weather affects tourist satisfaction and revisit intention directly and indirectly, and that it correlates with the perceived quality of physical attributes and service. It was determined that the impact of weather perception on tourist satisfaction and revisit intention is higher in rainy weather conditions. The results of the study show that to sustain tourist satisfaction and revisit intention, efforts to moderate the negative impacts of uncomfortable weather conditions are required, especially in rainy weather.

Accurate Meanings of Letters of the 'Neungpadae' Rock Inscription in Hahoe Village

Abstract Hahoe Village, one of the representative clan villages to which the Pungsan Ryu clan emigrated in the Goryeo era (13th century) is located in Andong City, Korea. There is a rock in the village called Neungpadae, on which is engraved an inscription which has been interpreted to mean Look down on waves (flood), because the Chinese character non-displayed special character(s) means look down on and the character non-displayed special character(s) means waves. People have stretched the meaning of these letters and interpreted them as Even if the Nakdong River overflows and produces a great flood, the flood water will not reach this rock, Neungpadae. The rock looks down on a flood (Andong City, 2002). However, this is an interpretation based only on the meanings of the two Chinese characters, non-displayed special character(s), and has not yet been authenticated. This study aims to discover the accurate meaning of Neungpadae in Hahoe Village and debunk the widely known, but incorrect interpretation.

Creation of Green Culture and Values in the Hanul Madang Rooftop Garden at Seoul National University

This chapter discusses green roof policies and practices in Korea and introduces a case study of a rooftop garden at Seoul National University. Seoul City has greatly grown since the 1970s and is still expanding through urban development projects. This rapidly developing urban environment makes it very difficult to conserve green spaces. Since the 2000s, Seoul City’s policy has been increasingly concerned with qualitative growth indicators for green and livable cities. Impervious surfaces cover 48% of the total area of Seoul, i.e., the majority of the urbanized area is covered by impervious surfaces. Therefore, green roofs were included in the 2030 Seoul City Park and Green Space Master Plan, because they are a very effective way of increasing the quantity and quality of urban green spaces. Rooftop greening is a very effective way of contributing to green cities, because it is an economical way to utilize the available space. Previous studies on the value and benefit of green roofs in sustainable cities are summarized, and two types of green roofs are described. The first type is a leisure and recreation space to enrich the green culture in the urban environment, where there is a lack of greenery, while the other type has more ecological effects and aims to enhance the environment through greening of artificial grounds. The type of rooftop garden is decided at the beginning of its installation, which can be distinguished by an intensive or extensive system. In this chapter, the case of the Hanul Madang rooftop garden, built at Seoul National University, is introduced as an example of the use, as well as the ecological and cultural values, of rooftops.

The Current Status of BIM in the Field of Landscape Architecture and the Issues on the Adoption of LIM

Since the new millennium, BIM has been widely adopted to improve productivity in the field of architecture, engineering, and construction with the government policies of each country. After its first introduction into the field of landscape architecture in USA, BIM has been debated on its merits and limitations mainly by the European countries academic and, at the same time, practical worlds. However, little attention has been paid to BIM, in particular, in the field of landscape architecture in Korea leaving many issues to solve to fully utilize BIM. The purpose of this study is to present the main issues and strategic agenda for the successful introduction of BIM in landscape architecture in Korea. This study shows that the new derived word of LIM(Landscape Information Modeling) instead of BIM appeared in the field of landscape architecture. Then, this paper discusses the main issues on standardization and interoperability in the adoption of LIM to create, integrate, and reuse landscape information. Finally, four strategic agenda are presented to successfully introduce LIM into the domestic field of landscape architecture by reviewing the societies of the landscape discipline in UK and Norway that play a leading role by organizing BIM working groups.
