This study aims to apply Hannah Arendt's concept of 'collective responsibility' to the Christian education on environmental issues around the world, focusing on climate change. This study prepares the concept of 'collective responsibility' and the concept of 'collective guilt' and emphasizes the fact that the current climate change problem should be seen as a political task rather than a task of personal ethics. According to Arendt's theory, Christian education activities applying 'collective responsibility' for climate change can become action. This study has four suggestions for Christian learning to understand and recognize climate change. First, presenting and justifying the anxiety and anger toward climate change in the classroom. Second, transcending self-interest (egocentrism) through "Common Sense (enlarged mentality)" in Kantian terms. Third, building education communities through 'citizen participatory education,' running communication, and conversation. Fourth, encouraging experience and practice in every education community with "faith expressing itself through love (Gal 5:6)." Then, to be sure, this refers to not only love of neighbor in Christianity but also political friendship (philia politikē). The academic significance of this study is that it is the first interdisciplinary research paper in Korea which dealt with Arendt's political theory in relation to Christian education. Although it claims to be a theoretical work that applies Arendt's political theory from a systematic theological perspective to Christian education, the author is proud that it is accompanied by practical elements that can be actualized in the education field.

In this paper, visible light wireless communication system according to the climate is studied in the marine environment. The light visibility can be determined by the different weather conditions (clear air, rain, storm, fog) in Kim's atmospheric channel model. By simulating the OOK-NRZ modulation technique, the BER performances are compared in the different weather conditions. In the field test, the error bit is measured in the visible-light communication. The effectiveness of visible light communication in the marine environment is confirmed by comparing the analysis of simulations and field experiments.

Purpose: Communication in hospitals is one of the major factors in patient safety. So, the purpose of this study was to identify the relationship between intra-organizational communication satisfaction and the safety attitude of nurses in hospitals. Method: A descriptive survey design with convenience sampling was used. Data collection was done using a self-report questionnaire answered by 278 nurses from one university hospital located in Kyeoung-gi Province, Korea. Result: Intra-organizational communication satisfaction positively correlated with safety attitude (r=.747, p<.01). Among the 6 sub dimensions of safety attitude, perceptions of management (r=.675, p<.01), job satisfaction (r=.640, p<.01) and teamwork climate (r=.600. p<.01) were strongly related to intra-organizational communication satisfaction. Multiple regression analysis was done to identify explanation power of intra-organizational communication satisfaction against safety attitude. The model was significant (F=48.540, p<.01). Intra-organizational communication satisfaction accounted for 60.9% of variance in safety attitude (Adj $R^2$=.609). Conclusions: The results of this study indicate that higher levels of intra-organizational communication satisfaction promote positive safety attitude in hospital nurses and that communication media quality is an important factor in patient safety attitude. Therefore, developing interventions to revitalize intra-organizational communication level based on communication media quality will help in the construction of positive safety attitude in nurses.

To understand the dynamics of radial growth of trees and micro-climate at a site of Korean fir (Abies koreana Wilson) forest on high-altitude area of Mt. Hallasan National Park, Jeju Island, Korea, high precision dendrometers were installed on the stems of Korean fir trees, and the sensors for measuring micro-climate of the forest at 10 minutes interval were also installed at the forest. Data from the sensors were sent to nodes, collected to a gateway wireless, and transmitted to a data server using mobile phone communication system. By analyzing the radial growth data for the trees during the growing season in 2016, we can estimate that the radial growth of Korean fir trees initiated in late April to early May and ceased in late August to early September, which indicates that period for the radial growth was about 4 months in 2016. It is interesting to observe that the daily ambient temperature and the daily soil temperature at the depth of 20 cm coincided with the values of about 10 ℃ when the radial growth of the trees initiated in 2016. When the radial growth ceased, the values of the ambient temperature went down below about 15 ℃ and 16 ℃, respectively. While the ambient temperature and the soil temperature are evaluated to be the good indicators for the initiation and the cessation of radial growth, it becomes clear that radii of tree stems showed diurnal growth patterns affected by diurnal change of ambient temperature. In addition, the wetting and drying of the surface of the tree stems affected by precipitation became the additional factors that affect the expansion and shrinkage of the tree stems at the forest site. While it is interesting to note that the interrelationships among the micro-climatic factors at the forest site were well explained through this study, it should be recognized that the precision monitoring made possible with the application of high resolution sensors in the measurement of the radial increment combined with the observation of 10 minutes interval with aids of information and communication technology in the ecosystem observation.

The study aims to identify the complex effects of information security (IS) environments and individuals' IS-related perceptions and value dissimilarity that negatively affect insiders' IS compliance activities. In detail, the study aimed to confirm the roles of prospective and inhibitory anxiety, and value dissimilarity in the process in which a competitive psychological climate negatively affects IS compliance intentions. The study obtained 387 samples from the firm's workers with IS-related regulations and verified the research hypotheses established using the AMOS 22.0 and Process 3.1 tools. As a result, the competitive psychological climate negatively affected IS compliance intention by increasing individual's IS-related prospective and inhibitory anxiety. In addition, IS-related value dissimilarity had an interactive effect with prospective and inhibitory anxiety and had a negative effect on IS compliance intention. This study has practical implications in terms of presenting information and values to be provided to employees to achieve internal IS goals and has academic implications in terms of applying the complex effects of IS-related anxiety and value dissimilarity.

This study aims to select ESG items from a consumer perspective and examine the influence of these factors on corporate image and corporate reputation. ESG-related research tends to be conducted from a corporate or investment perspective. However, based on their evaluation of ESG activities, consumers form corporate image and corporate reputation. Accordingly, the E, S, and G evaluation items were applied from the consumer's perspective to analyze the impact of each item. As a result of the study, the impact on corporate image was found to be in the order of transparent management, support for small and medium-sized businesses, and response to climate change. The results of corporate reputation analysis showed transparent management, response to climate change, and support for small businesses. From the consumer's perspective, activities related to a company's response to climate change are considered a corporate obligation, and demands for coexistence and transparent corporate management of small and medium-sized businesses are growing. The significance of this study is that ESG requires environmental management, symbiotic management, and transparent management from a consumer point of view, suggesting that transparent corporate management is the most important factor. In addition, it suggests that communication with consumers of companies requires communication not only in the environmental area, but also in the social and governance areas.

The required standards for environmental tests for communication and electronic equipment used currently are not standards into which the Korean climate and use environment are taken into consideration. But the most used environmental testing standards of the U.S. army(MIL-STD-810) has been used without taking into consideration the Korean domestic situation and conditions by simply translating the US standards. Adherence to these standards may increase in the manufacturing costs according to excessively strict standards. Therefore, this paper will propose a new environmental test standards for temperature.
