The purpose of this research is to figure out the effects of media framing and image restoration strategies on the public's crisis perceptions. The literature review revealed that the public perceives crises through the media lens and image restoration strategies heralded by the organization interact with media frames in the process of the public's perceiving the crisis. The news content analysis and the experiment were conducted to accomplish the research purpose. Also food-related crises were selected for a research case because they have a great impact on the society. The content analysis showed that image restoration strategies designed by the crisis organization tend to be conveyed through anecdote-type news frames. Most image restoration strategies were close to defensive communications and not differentiated by the crisis type. The experiment outcomes demonstrated that the organization's image restoration strategies were not consistent with what the public preferred in the crisis situation. Such public perceptions also were changed according to media frames. Media frames and image restoration strategies have an interaction effect on the public's crisis perception.

This study examined image restoration strategies of political parties regarding the Presidential impeachment In Korea. The analytic framework of this study was Benoit's rhetorical theory of image restoration strategies. Results showed that both Hanara Party and Minju Party used attack accuser as a major image restoration strategy. However, Hanara Party changed their strategies from attack accuser to future oriented. Thus, Hanara Party's image restoration strategy successfully applied Coombs theory, which future oriented strategy was good for an organization of the high responsibility in the context of crisis situation.

The public trades information through social media during crises. The use of social media during crises has been increased steadily. However, there are few studies done on the effects of social media use on crisis perception. The goal of this study is to examine how social media affect an organization's ability to manage crises. The study specifically tries to investigate how media types, organization-public relationships, and image restoration strategies affect the public's perception of crises. An experiment was conducted to test research questions by presenting crisis scenarios and observing how newspapers and the social media Twitter affected the crisis. According to a three-way ANOVA test, the type of media and image restoration strategies had an interaction effect on the public's perception of crises. Also, the type of media, organization-public relationship, and image restoration strategies had a three way effect toward the acceptance of crisis communication strategies. As a result, it can be said that the public's perception and acceptances of crisis communication were different depending on the type of media used. The effectiveness of social media was proved, and it was seen that to be able to effectively use social media, each organization must have different strategies depending on their needs.

The purpose of this study was to minimize the forest disturbance around an entry road of a power transmission tower construction site between Taean and Sinsesan, Chungnam. The main study field was classified into existing materials and a GIS, remote sensing analysis, and a field examination. This information was used to identify the most suitable entry road using a degree of green naturality map, eco-naturality map, actual vegetation map, and a forest state map as the existing materials. Also, the study used an normalized difference vegetation index, altitude and slope map in order to make the evaluation materials which used an remote sensing image, and GIS. This data was used to choose an optimum area, and diagnosed the current condition of the vegetation with a field survey of the area. It analyzed vegetation structure, species diversity, the age of trees in a field examination. Subsequently, we proposed four area types based on the analysis results--preservation area, transplantation area, restoration area and development area. As a result, the preservation area was categorized into 8 grades, according to the degree of green naturality, large area of breast diameter at Pinus densiflora community, competition area of Pinus densiflora and Quercus spp. and Quercus spp. community of over 20 years old. A transplantation area established 46 optimum areas according to the GIS analysis and vegetation investigation results. Vegetation restoration plan for disturbance area should be made based on ecological value of existing vegetation to worthwhile area as Quercus spp. mixing forest proposed. The development area selected a ecological worthless place as an artificial forest where Pinus densiflora and Pinus thunbergii growth is poor. This research results suggest that restoration of vegetation will be possible in the real world. Also, ecological restoration guidelines will be made through building and analyzing data base and routine monitoring of transplantation and restoration area.

This study finds that the South Korean government's public diplomacy efforts have focused on promotional activities such as the "K-wave" or responses to controversial historical issues. However, the South Korean government needs to be more prepared for strategic responses to unexpected crises and subsequent communications. This paper attempts to apply crisis communication research developed in the field of public relations to public diplomacy. To do so, this research reviewed theories in crisis communication, an essential area of public relations, and developed a crisis communication model. The model was then applied to several crisis case studies to suggest how to develop response strategies and conduct communications. As a result, this research developed an Ongoing Public Diplomacy Crisis Communication Model (PDCCM) that can be applied to public diplomacy research and practice. The model identifies four crisis communication principles (be quick, be open, be consistent, be authentic) that should be applied in six phases. Following continuous social listening and monitoring, governments should analyze crisis situations using sense-making, develop short- and long-term crisis response objectives, response strategies, and communication messages depending on the level of responsibility, implement crisis communication, and conduct post-crisis evaluation.

This paper puts forward protection strategies for the environmental problems of Busan coastline, providing theoretical basis and guiding standards for the tourism development and environmental transformation of the coastline. The order of research is to deduce the factors that affect environmental problems from the theoretical coastline development characteristics. The investigation method of spatial structure combined with time axis is adopted, and historical images and image processing techniques are used to find the characteristics of morphological changes of Busan coastline. The three types of natural coastline, artificial coastline and ecological restoration coastline are analyzed through the five factors that affect the fluctuation, extensibility, greening rate, concealment and vision of space. According to the above discussion, international competition examples are introduced to find solutions. Finally, environmental protection schemes are put forward from five aspects of tourism, accidents, development, culture and transformation. In the future research, it will focus on the transformation of coastline space to provide a more humanized activity space for coastline residents.

The color appearance of cultural heritage are essential factors for manufacturing technique interpretation, conservation treatment usage, and condition monitoring. Therefore, this study systematically established color reproduction procedures based on the digital color management system for the portrait of Gwon Eungsu. Moreover, various application strategies for recording and conserving the cultural heritage were proposed. Overall color reproduction processes were conducted in the following order: photography condition setting, standard color measurements, digital photography, color correction, and color space creation. Therefore, compared with the color appearance, the digital image applied to a camera maker profile indicated an average color difference of 𝜟10.1. However, the digital reproduction result based on the color management system exhibits an average color difference of 𝜟1.1, which is close to the color appearance. This means that although digital photography conditions are optimized, recording the color appearance is difficult when relying on the correction algorithm developed by the camera maker. Therefore, the digital color reproduction of cultural heritage is required through color correction and color space creation based on the raw digital image, which is a crucial process for documenting the color appearance. Additionally, the recording of color appearance through digital color reproduction is important for condition evaluation, conservation treatment, and restoration of cultural heritage. Furthermore, standard data of imaging analysis are available for discoloration monitoring.

This study aimed to develop a precise vegetation cover classification model for small streams using the combination of drone remote sensing and support vector machine (SVM) techniques. The chosen study area was the Idong stream, nestled within Geosan-gun, Chunbuk, South Korea. The initial stage involved image acquisition through a fixed-wing drone named ebee. This drone carried two sensors: the S.O.D.A visible camera for capturing detailed visuals and the Sequoia+ multispectral sensor for gathering rich spectral data. The survey meticulously captured the stream's features on August 18, 2023. Leveraging the multispectral images, a range of vegetation indices were calculated. These included the widely used normalized difference vegetation index (NDVI), the soil-adjusted vegetation index (SAVI) that factors in soil background, and the normalized difference water index (NDWI) for identifying water bodies. The third stage saw the development of an SVM model based on the calculated vegetation indices. The RBF kernel was chosen as the SVM algorithm, and optimal values for the cost (C) and gamma hyperparameters were determined. The results are as follows: (a) High-Resolution Imaging: The drone-based image acquisition delivered results, providing high-resolution images (1 cm/pixel) of the Idong stream. These detailed visuals effectively captured the stream's morphology, including its width, variations in the streambed, and the intricate vegetation cover patterns adorning the stream banks and bed. (b) Vegetation Insights through Indices: The calculated vegetation indices revealed distinct spatial patterns in vegetation cover and moisture content. NDVI emerged as the strongest indicator of vegetation cover, while SAVI and NDWI provided insights into moisture variations. (c) Accurate Classification with SVM: The SVM model, fueled by the combination of NDVI, SAVI, and NDWI, achieved an outstanding accuracy of 0.903, which was calculated based on the confusion matrix. This performance translated to precise classification of vegetation, soil, and water within the stream area. The study's findings demonstrate the effectiveness of drone remote sensing and SVM techniques in developing accurate vegetation cover classification models for small streams. These models hold immense potential for various applications, including stream monitoring, informed management practices, and effective stream restoration efforts. By incorporating images and additional details about the specific drone and sensors technology, we can gain a deeper understanding of small streams and develop effective strategies for stream protection and management.

Since municipal welfare institutions operate for different purposes from general companies or public enterprises, ESG practice items and model construction should be conducted through various and comprehensive social welfare studies. Since there are not many studies available in domestic welfare institutions yet and there are no suitable ESG management utilization indicators, the Cheonan Welfare Foundation's strategy and management strategy system were established to spread the model to other welfare institutions and become a leading foundation through education and training. The foundation and front-line welfare institutions selected issues identification and key issues through the foundation's empirical analysis and criticality analysis, focusing on understanding ESG management and ways to establish a practice model that positively affects institutional image and business performance. Based on this, the promotion system was examined by establishing a performance management plan after deriving appropriate strategies and establishing a strategic system for social welfare institutions. Environmental and social responsibility, transparent management, safety management system establishment, emergency and prevention, user (customer) satisfaction system establishment, anti-corruption prevention and integrity ethics monitoring and evaluation, responsible supply chains, and community contribution programs. This study attempted to specifically present efforts to settle ESG management through the consideration of the Cheonan Welfare Foundation. Therefore, it is considered to be useful data for developing ESG management by referring to the systematic development process of the Cheonan City Restoration Foundation to develop ESG measurement indicators.
