This study examines the drama "Still in Marronnier Park"(2005) to examine the strategies by which the drama communicates Korean society and literature of the 1960s to the public. The drama focuses on three characters to characterize the historical upheavals of the 1960s and the literary response. In particular, the drama tackles the historical events of the time head-on by introducing characters who are real-life politicians. Therefore, the drama explains historical events through narrators, interviews, and video footage, and at the same time, it helps us understand how political and social events affected the inner lives of Koreans. Through the narratives of Kim Ji-ha and Kim Seung-ok, the drama also conveys how Korean literature responded to unjust realities in the political and social context of the 1960s. Kim Ji-ha's rebellion against those in power and Kim Seung-ok's depiction of her inner landscape are used to portray the response of literature to political reality. Although the drama has the limitation of being somewhat typical, it raises meaningful questions about the meaning of literature in the political and social context of the 1960s and how the memory of the 1960s has left a trace in the minds of Koreans.

After the strongest El Niño since 2015 occurred in 2023, there has been a growing interest in understanding its impacts on rice yield in South Korea. We investigated the impact of El Niño during the rice-growing season on rice yield by analyzing the correlation between detrended rice yield data and ONI (Oceanic Niño Index) values exceeding 0.5. The results show a positive correlation between ONI intensities and detrended rice yields. Furthermore, we found that variations in sunshine duration, precipitation, and typhoon activity affect detrended yield values positively and negatively. This pattern was similar to the classification of El Niño into Cold Tongue El Niño and non-Cold Tongue El Niño, which showed positive and negative detrended rice yield values, respectively. This observation suggests that predicting yield based on ONI intensity during Cold Tongue El Niño years may be feasible to some extent.

Severe casualties and property damage are occurring due to urban floods caused by extreme rainfall. However, there is a lack of research on preparedness, appropriate estimation of flood damages, assessment of losses, and compensation. Particularly, the flood damage estimation methods used in the USA and Japan show significant differences from the domestic situation, highlighting the need for methods tailored to the Korean context. This study addresses these issues by developing an optimized flood damage estimation technique based on the building characteristics. Utilizing the flood prediction solution developed by the Korea Institute of Science and Technology Information (KISTI), we have established an optimal flood damage estimation technology. We introduced a methodology for flood damage estimation by incorporating vulnerability curves based on the inventory of structures and apply this technique to real-life cases. The results show that our approach yields more realistic outcomes compared to the flood damage estimation methods employed in the USA and Japan. This research can be practically applied to procedures for flood damage in urban basement residences, and it is expected to contribute to establishing appropriate response procedures in cases of public grievances.

This study aims to investigate stream drying phenomena and determine ecological flow in upper Jungnangcheon basin(118.2 km²) of Han River basin. Satellite imagery was used to compare historical and current land cover, and field surveys, including fish surveys, were conducted to assess stream drying conditions. Satellite image analysis revealed a significant increase in impervious surface area due to the expansion of residential and commercial areas. Streamflow and water quality measurements at Hannae Bridge in study area during the dry season showed and average minimum flow of 1.39 m³/sec and elevated SS levels, indicating poor water quality for T-P and TOC. The representative fish species in the study area was P.herzi. Optimal habitat suitability index for depth, velocity, and substrate were 0.3~0.5 m, 0.1~0.3 m/sec, and sand, respectively. Using PHABSIM, the ecological flow for the study area was estimated as 1.00 m³/sec. The derived ecological flow can be used as a reference flow for stream drying mitigation strategies.

As the number of cases of applying IT systems to the existing isolated ICS (Industrial Control System) network environment continues to increase, security threats in the ICS environment have rapidly increased. Security threat scenarios help to design security strategies in cybersecurity training, including analysis, prediction, and response to cyberattacks. For successful cybersecurity training, research is needed to develop valid and reliable security threat scenarios for meaningful training. Therefore, this paper proposes a case-based security threat scenario development methodology for cybersecurity training in the ICS environment. To this end, we develop a methodology consisting of five steps based on analyzing actual cybersecurity incident cases targeting ICS. Threat techniques are standardized in the same form using objective data based on the MITER ATT&CK framework, and then a list of CVEs and CWEs corresponding to the threat technique is identified. Additionally, it analyzes and identifies vulnerable functions in programming used in CWE and ICS assets. Based on the data generated up to the previous stage, develop security threat scenarios for cybersecurity training for new ICS. As a result of verification through a comparative analysis between the proposed methodology and existing research confirmed that the proposed method was more effective than the existing method regarding scenario validity, appropriateness of evidence, and development of various scenarios.

The present study examines the dual mediating role of social support and self-esteem in the relationship between grit and life satisfaction among college students. Utilizing a cross-sectional design, we surveyed a sample of 326 undergraduates from one university in China by means of purposive sampling. The analyses were conducted using SPSS PC+ Win. ver. 25.0 and SPSS PROCESS macro ver. 4.2. Pearson's correlation analysis was performed to show the correlations among the variables, and Model 6 of the PROCESS macro for SPSS was used to verify dual mediation effects. First, correlation results indicated positive and significant correlations between grit, social support, self-esteem and life satisfaction. Second, the dual mediating role of social support and self-esteem in the relationship between grit and life satisfaction was proved. This study contributes to the literature by elucidating the psychological mechanisms through which grit operates to enhance life satisfaction. The results have implications for the development of interventions aimed at fostering grit and the enhancement of social support and self-esteem to improve life satisfaction. Suggestions for future studies were discussed in detail.

The creation of open spaces has both direct and indirect impacts on the local economy, society, culture, and environment. Since the public usually finances these spaces, it is necessary to ensure procedural rationality by promoting consensus among residents and other stakeholders. This study examines the extent of public participation in the creation of open spaces and summarizes trends. By analyzing seven cases of open space development based on participation in South Korea, the study identifies the characteristics and progression of participation during four phases of the development process in the Gwanghwamun Plaza Restructuring Project (2016-2022). During the agenda-setting phase, the Gwanghwamun Forum was convened to establish agendas for the plaza's restructuring. The design and governance phase included a design competition to select a proposal for the plaza, alongside the establishment of the Gwanghwamun Citizens' Committee for governance. Despite proactive efforts in the conflict resolution phase to halt extensive restructuring and enhance communication, civic groups opposed the project by presenting five distinct agendas. In the implementation phase, multiple public participation programs were conducted before the plaza's reopening. The study found that public participation in the Gwanghwamun Plaza project faced challenges such as inadequate participation conditions, limited information sharing, and monotonous participation opportunities. Although the institutional environment for public participation is improving, practical limitations remain. Therefore, a comprehensive examination of open space creation through public participation is necessary.

The burden of medical expenses and the loss of social capital due to chronic diseases are becoming problems worldwide, and comprehensive and inclusive measures across various fields are required to prevent and manage their impacts. Social prescriptions have been shown to be effective in resolving the fundamental causes of health problems in patients with chronic diseases and in supporting existing treatments. In particular, green prescriptions that utilize the healing effects of nature and green spaces based on social prescriptions are being introduced in many countries overseas. Green prescription is the practice of a healthcare provider recommending activities in green spaces or experiences in the natural environment to patients for the prevention and management of chronic diseases. This study analyzed cases focusing on the policy system, the cases of the United Kingdom and the United States, which have introduced and operated green prescriptions under a national system. For this purpose, this study compared the background of green prescription introduction, related policies, and operation methods. Based on this, four implications were proposed to establish an effective plan for introducing green prescriptions in Korea. First, prior to establishing a policy for green prescriptions, interest in and research on green prescriptions are essential. Second, an implementation plan that fits the national health care system should be established, and policies should support the plan. Third, the introduction of green prescriptions from a long-term and gradual perspective is required. Fourth, comprehensive cooperation is required for the introduction and implementation of the green prescription system. This study can be used as basic data for discussion before introducing green prescriptions in Korea in the future.

Recently, wind power has been gaining attention as a highly efficient renewable energy source, leading to various technological developments worldwide. Typically, wind power is operated in the form of large wind farms with many wind turbines installed in areas rich in wind resources. However, in developing countries or regions isolated from the power grid, off-grid small wind power systems are emerging as an efficient solution. To efficiently operate and expand off-grid small-scale power systems, the development of real-time monitoring systems is required. For the efficient operation of small wind power systems, it is essential to develop real-time monitoring systems that can actively respond to excessive wind speeds and various environmental factors, as well as ensure the stable supply of produced power to small areas or facilities through an Energy Storage System (ESS). The implemented system monitors turbine RPM, power generation, brake operation, and more to create an optimal operating environment. The developed small wind power system can be utilized in remote road lighting, marine leisure facilities, mobile communication base stations, and other applications, contributing to the development of the RE100 industry ecosystem.
