This empirical study is to verify the moderating effects of environmental education on pro-environmental consumers. For this purpose, we used Value-Attitude-Behaviro Model(VAB). In addition, as an environmental education method, the environmental education method using 7 environmental movies by the multimedia with excellent learning effect in order to increase the interest and educational commitment of the learners was utilized. A total of 116 subjects were divided into experimental group and control group, and the experiment was designed based on Pretest-Posttest Control Group Design to grasp the effect of environmental education after conducting environmental education to the experiment group. The results of the analysis showed that environmental education had no effect on environmental values but it had a positive effect on improving the attitude and the pro-environmental behavior. This study proved that the sustainable environmental education could form pro-environmental behavior, even though the environmental sense of values had not been formed in adolescence, and furthermore, the earlier researches had been mainly focused on the effect of the environmental education for the adolescent.

South Korea and Vietnam have been engaged in extensive political, economic and cultural exchanges since the establishment of diplomaticties in 1992. In March 2018, Moon Jae-in, President of South Korea, made an official visit to Vietnam, a key partner of the New Southern Policy and discussed comprehensive cooperation measures, including expanding trade volume and measures to establish peace on the Korean Peninsula. At the defense ministers' meeting held in April 2018, the two countries signed a joint defense and defense cooperation statement, which included promotion of maritime security, defense cooperation, UN PKO activities, excavation of remains, and joint military cooperation. Currently, Vietnam is facing territorial disputes with China over the South China Sea, and is stepping up military modernization and military buildup to counter this. In particular, Vietnam is strengthening its external military cooperation beyond ideology with the U.S., Russia, India and France to strengthen its maritime power. Against this backdrop, the bilateral cooperation between South Korea and Vietnam needs to expand beyond the traditional economic and cultural exchanges to military cooperation. The study aims to review the relationship between South Korea and Vietnam on the 26th anniversary of the normalization of diplomaticties and seek ways to develop military cooperation with Vietnam, which has grown to the next China. To that end, it analyzed Vietnam's security environment and military strategy and presented strategies for promoting military cooperation focusing on defense areas.

The purpose of this study is to investigate the conditions for improving space use and satisfaction by examing the behavior, focusing on the senior center, one of the leisure welfare facilities for the older adults. An online survey was conducted on 300 older adults aged 65 years old (104 males, 196 females) who had experience using senior centers. The results are as follows. First, the frequency of use per older adults was 1-3 times a month the most, and the preferred frequency of use was 1-3 times a week. The results showed that they wanted to use the Senior center frequently, but they could not use it often. Considering the high preference for health promotion activity programs in senior centers, it is understood that the use of space programs for health promotion can be increased if provided. Second, as the usage time per route ranges from a minimum of 1 hour to a maximum of 5 hours, it is considered that satisfaction and usability can be improved if a space to support various personal activities is provided. Third, it is considered to be helpful to improve the program or space composition that can strengthen friendship or improve accessibility by appearing as difficulties in friendship and accessibility for the reasons not used per senior citizen.

The "cognitive warfare," which has emerged as a result of the Ukrainian-Russian war, has already existed in the previous war and is now emerging as a major aspect of the war, its meaning and influence are increasing. Recognizing the emergence and importance of cognitive warfare and understanding the meaning and characteristics of cognitive warfare must be accompanied by victory in the modern war. After Russia's alleged involvement in the U.S. presidential election in 2016 drew attention, the Israeli-Palestinian conflict in 2021 confirmed its upward influence. In particular, 'cognitive warfare' using SNS played a major role in leading the war to its advantage and maintaining the initiative by selecting clear purposes and targets such as the international community, the people, and Hamas. This new pattern of war is gradually emerging as the world is hyper connected with the advent of the Fourth Industrial Revolution. It is expected that it will play a leading role in the future battle if it clearly recognizes the main contents of the new war, "Injijeon," and has the ability and ability to actively operate it.

Due to man-made climate change, global abnormal weather phenomena have occurred, increasing disasters. Major developed countries(military) are preparing for disasters caused by extreme weather appearances. However, currently, disaster prevention plans and facilities have been implemented based on the frequency and intensity method based on statistical data, it is not enough to prepare for disasters caused by frequent extreme weather based on probability basis. The U.S. and British forces have been the fastest to take research and policy approaches related to climate change and the threat of disaster change, and are considering both climate change mitigation and adaptation. The South Korean military regards the perception of disasters to be storm and flood damage, and there is a lack of discussion on extreme weather and disasters due to climate change. In this study, the process of establishing disaster management systems in developed countries(the United States and the United Kingdom) was examined, and the response policies of each country(military) were analyzed using literature analysis techniques. In order to maintain tight security, our military should establish a response policy focusing on sustainability and resilience, and the following three policy approaches are needed. First, it is necessary to analyze the future operational environment of the Korean Peninsula in preparation for the environment that will change due to climate change. Second, it is necessary to discuss climate change 'adaptation policy' for sustainability. Third, it is necessary to prepare for future disasters that may occur due to climate change.

This research is a comparative analysis of the U.S. S&P 500 index using the volatility breakout strategy against the Buy and Hold approach. The volatility breakout strategy is a trading method that exploits price movements after periods of relative market stability or concentration. Specifically, it is observed that large price movements tend to occur more frequently after periods of low volatility. When a stock moves within a narrow price range for a while and then suddenly rises or falls, it is expected to continue moving in that direction. To capitalize on these movements, traders adopt the volatility breakout strategy. The 'k' value is used as a multiplier applied to a measure of recent market volatility. One method of measuring volatility is the Average True Range (ATR), which represents the difference between the highest and lowest prices of recent trading days. The 'k' value plays a crucial role for traders in setting their trade threshold. This study calculated the 'k' value at a general level and compared its returns with the Buy and Hold strategy, finding that algorithmic trading using the volatility breakout strategy achieved slightly higher returns. In the future, we plan to present simulation results for maximizing returns by determining the optimal 'k' value for automated trading of the S&P 500 index using artificial intelligence deep learning techniques.

The purpose of this study is to study how to apply block-chain technology to prevent data forgery and alteration in the defense sector of AI(Artificial intelligence). AI is a technology for predicting big data by clustering or classifying it by applying various machine learning methodologies, and military powers including the U.S. have reached the completion stage of technology. If data-based AI's data forgery and modulation occurs, the processing process of the data, even if it is perfect, could be the biggest enemy risk factor, and the falsification and modification of the data can be too easy in the form of hacking. Unexpected attacks could occur if data used by weaponized AI is hacked and manipulated by North Korea. Therefore, a technology that prevents data from being falsified and altered is essential for the use of AI. It is expected that data forgery prevention will solve the problem by applying block-chain, a technology that does not damage data, unless more than half of the connected computers agree, even if a single computer is hacked by a distributed storage of encrypted data as a function of seawater.
