This study aims to understand microaggressions directed toward international students from the perspective of international exchange professionals, who tend to be in relatively close contact with international students. This study targeted professionals who directly advise and support international students at university international exchange centers in J and G cities. The data were collected by conducting focus group interviews with seven participants in two groups from 25 May to 8 June 2023. Data were collected by conducting focus group interviews of seven participants in two groups from 25 May to 8 June 2023. After analyzing the interview data using thematic analysis, two themes emerged: the experiences of international students and the perspectives of international exchange professionals. The experience of international were further categorized into three sub-themes: differences in cultural context, academic discrimination, and discrimination due to lack of information. The perspectives of international exchange professionals were further categorized into three sub-themes: limited access to infrastructure, different perspectives depending on the level of the country, and consideration as a barrier. It is hoped that the findings of this study, obtained by exploring the microdiscrimination faced by international students at universities, will facilitate the development of different systems and policy recommendations to improve the experiences of international students.

Structural vibration induced by earthquake hazards is one of the most significant concerns in structure performance-based design. Structural hazards evoked from seismic events must be properly identified to make buildings resilient enough to withstand extreme earthquake loadings. To investigate the effects of combined earthquake-resistant systems, shear walls and five types of dampers are incorporated in nineteen structural models by altering their arrangements. All the building models were developed as per ACI 318-14 and ASCE 7-16. Seismic fragility curves were developed from the incremental dynamic analyses (IDA) performed by using seven sets of ground motions, and eventually, by following FEMA P695 provisions, the collapse margin ratio (CMR) was computed from the collapse curves. It is evident from the results that the seismic performance of the proposed combined shear wall-damper system is significantly better than the models equipped with shear walls only. The scrutinized dual seismic resisting system is expected to be applied practically to ensure a multi-level shield for tall structures in high seismic risk zones.

In South Korea, over 400,000 Non-building Structures are inadequately managed and exposed to potential risks due to insufficient inspection systems, leading to an increase in accidents and significant losses of life and property. Therefore, it is crucial for users to conduct proactive self-inspections to identify and mitigate potential hazards. This study reclassified Non-building Structures into four main categories by analyzing their structural characteristics and associated risks through statistical analysis. Among these, retaining walls, which account for the largest proportion, were systematically analyzed to identify common damage patterns. Based on this analysis, self-inspection checklists were developed for both non-experts and experts. The proposed process involves an initial visual inspection using a simple non-expert checklist, followed by a more detailed expert-level inspection if any anomalies are detected. The reliability of this process was validated through approximately 120 validation processes.

The purpose of this study is to suggest the management criteria through the decision tree analysis for a seepage, which is an important instrumentation type of the fill dam. In the case of the seepage of the dam in Korea, seepage can be increased rapidly because rainfall directly flow into the downstream slope and abutment of dam during rainfalls. Therefore, it is necessary the management criteria for the seepage of the fill dam in consideration of rainfall. In this study, decision tree analysis was performed for a fill dam in Korea by setting the seepage as the response variable and the rainfall and water level of dam as explanatory variables. As the study results, the water level acted as an explanatory variable from the conditions under daily rainfall of 34.75 mm/day, and the branch conditions of the water level were analyzed to be 37.4 m and 35.23 m. 98% of the rainfall data is distributed under the conditions of the daily rainfall of 34.75 mm/day, and coverage of the seepage is indicated from 13.25 L/min to 24.24 L/min. When the rainfall and water level as the influence factors for the seepage were selected, the influence of the rainfall was dominant. Finally, the seepage of fill dam by considering the rainfall and water level was suggested as a management criteria.

Flood caused by Typhoon and severe rain during summer is the most destructive natural disasters in Korea. Almost every year flood has resulted in a big lost of national infrastructure and loss of civilian lives. It usually takes time and great efforts to estimate the flood-related damages. Government also has pursued proper standard and tool for using state-of-art technologies. High resolution satellite imagery is one of the most promising sources of ground truth information since it provides detailed and current ground information such as building, road, and bare ground. Once high resolution imagery is utilized, it can greatly reduce the amount of field work and cost for flood related damage assessment. The classification of high resolution image is pre-required step to be utilized for the damage assessment. The classified image combined with additional data such as DEM and DSM can help to estimate the flooded areas per each classified land use. This paper applied object-oriented classification scheme to interpret an image not based in a single pixel but in meaningful image objects and their mutual relations. When comparing it with other classification algorithms, object-oriented classification was very effective and accurate. In this paper, IKONOS image is used, but similar level of high resolution Korean KOMPSAT series can be investigated once they are available.

This paper shows that the value of land can vary based on the future availability of the land. According to the Korean principles of land appraisal by the Ministry of Land, Infrastructure, and Transport (MOLIT), the value of a piece of land is derived mainly from the latter's fertility level or local environment. In practice, however, the values of lands may vary even though their fertility level is invariant. This paper investigates a fundamental question for many professional appraisers who argue that appraisal practices are different from the principles of appraisal. It highlights the appraisal practices for agricultural and forestry lands, which have similar agricultural productivity levels or environmental conditions. It is shown in this paper that even though the fertility level of lands is invariant, the values of lands may vary based on their locations. Therefore, this can complement the principles of land appraisal. In this paper, real cases in local areas in Gapyeong County, Kyounggi province are investigated. It can be seen from the cases in the local areas that two agricultural lands may have different values based on their locations even though they have almost similar fertility levels (e.g., their physical distance from each other is less than 0.5 km but their values differ by around 19%). This paper thus argues that the value of a piece of land can be determined by its availability.
