Abstract


Purpose: The complexity and safety of power facilities have increased very rapidly, yet efforts are insignificant in ensuring safety according to risks. Hence, the purpose of is, in order to help prevent safety accidents in advance, risk factors are listed through the risk analysis of power facilities, and to develop an augmented reality safety manual according to the improvement of risk scales to ensure the safety by conducting pre-simulation in the field and taking prompt response at the accident site.

Method: By enumerating the risk factors simultaneously with the causal analysis for the failure together with the impact of the failure mode of the components forming the power generation facility system for which the design failure mode effect analysis(DFMEA) technique is applied, and by developing the augmented reality (AR) based software’s for maintenance and repairs based on the details of improvement as per the level of risk (RPN), the methodology for maintenance and repairs is presented due to the expansion of the infectious diseases in the era of contactless.

Results: The development of augmented reality system(software) for maintenance implements the 2D and 3D facility exploded view and work manual, etc., which enable the actual work processes to be performed across various field environments according to emergency situations of power facilities, and the big data based field data, and through acquisition, it would be possible to establish a precision standard maintenance platform. Further-more, it is expected to have the effect of reducing the costs for accident prevention and maintenance work, and increasing the quality and quantity.

Conclusion: Through this study, the safety of electric power facilities and a preventive method in emergency situations are presented. The software development through augmented reality(AR) through the Design Failure Mode Effect Analysis(DFMEA) can help prevent accidents and implement condition based maintenance plans in an integrated system, and hence, a high efficiency can be expected. It is considered that accuracy, reliability, and safety improvement are required in future papers through the addition of risk points and continuous development of diagnostic algorithm libraries.

  • Purpose: A large-scale complex disaster refers to a disaster that develops on a huge scale outside the predictable range as natural disasters and social disasters occur serially or simultaneously. The local community must take into account the diversity of residents' situations and organize an evacuation cooperation system in advance in order to respond to such large-scale, complex disasters. The purpose of this paper is to present a direction for improving community response to disasters through a review of large-scale complex disasters. Method: This study examines the large-scale flood damage evacuation plan in the 5th district of Koto, Tokyo, Japan, which established an evacuation plan led by the local community after the Great East Japan Earthquake. Evacuation was divided into vertical evacuation, evacuating within the community, and wide area evacuation, evacuating outside the community. Results: The main features of these evacuation plans were that they encouraged local residents to make independent judgements, to implement the plans, and to proactively request and prepare for administrative support for the parts that were insufficient. Conclusion: First of all, for efficient evacuation from large-scale-complex disasters, various stakeholders need to be recognized and systematically organize, and cooperation with relevant and upper-level administrative agencies is needed to solve problems that are beyond the capacity of local governments. It is also necessary for residents to recognize their own role in disaster response along with the proper implementation of disaster prevention administration, and for the administration to support factors that residents cannot do as much as possible, as the basic structure of the crisis.

  • Purpose: The Kishida administration’s proposed Fukushima radioactive wastewater dumping plan is very controversial both domestically and internationally. This paper examines the risks and consequences of the plan with a special focus on human rights concerns. It argues that, as the Kishida administration commences the decommissioning of the Fukushima Daiichi Nuclear Power Station, it should only consider approaches that are consistent with a human-centric policy that is supportive of human rights. Method: This paper employs politics of responsibility theory to examine the Kishida administration’s proposed Fukushima radioactive wastewater dumping plan. In light of the current body of research on the decommissioning of the Fukushima Daiichi Nuclear Power Station by international scholars, scientists, and experts, it argues that the Kishida administration’s implementation of the proposed radioactive wastewater dumping plan represents a failure to govern with an eye to the politics of responsibility. Results: This paper finds that application of the Fukushima radioactive wastewater dumping plan under the Kishida administration will induce immense political, economic, social, and environmental consequences for Japanese citizens as well as citizens in neighboring countries and beyond. The Kishida administration is presently failing to pursue policies that reinforce a human-centric policy that would be more supportive of human rights. Conclusion: The Kishida administration must suspend the current plan to dump Fukushima’s radioactive wastewater into the Pacific Ocean and consider alternative methods that will not result in the radioactive pollution of the ocean. As it proceeds with the decommissioning of the Fukushima Daiichi Nuclear Power Station, it should focus on principles of governance emphasizing the politics of responsibility and take steps to abide by relevant international legal standards and human rights norms.

  • Purpose: In this study, in order to find a way to minimize water supply shortage, reliability analysis of water supply was conducted by operating the Andong and the Imha Dam. The purpose is to find a way to minimize water shortage by the allocation distribution model from the reliability analysis results. Method: In this study, in order to analyze the water supply reliability of Andong and Imha Dam, using the Al-location rule presented by Park et al(2007), based on the planned water supply of Andong and Imha Dam for a total of 360 months from 1993 to 2022, analyzed. From the analysis results, the reliability of stable water supply was evaluated. Results: In the case of supplying the planned water supply of Andong and Imha Dam, the analysis result of Rule(B), which considers the ratio of the storage and inflow of the dam in the reservoir operation analysis result, showed that the shortage of Andong Dam occurred the most at 23 months, Regarding the number of shortages of control points, Rule(A), which considers only the storage capacity of the dam, was found to be short at 39 months, which is the largest number of shortages. As for the frequency standard reliability, Rule(B) showed the highest reliability of 90%, but in the case of quantitative reliability, the reliability was similar in all cases. Conclusion: In the water supply reliability, the reliability of stable water supply by supplying only the planned water supply amount is 94%, 93%, and 90% in Rule(B) of the allocation distribution model. 5% at the Andong dam, 7% at the Imha dam, and 10% at the control point. When water supply is evaluated with frequency reliability, it is judged that countermeasures for the shortfall are necessary. Next, in the case of quantitative reliability, when only the planned water supply was supplied, it was analyzed to be 95%, 94%, and 95% in all methods, so that the quantitative reliability was higher than the frequency reliability.

  • Purpose: The Korean wave phenomenon is closely related to university students in Korea, and university students are greatly influenced by the Korean Wave phenomenon and experience and develop positive changes and opportunities through it. The Korean Wave phenomenon is contributing to university students introducing and promoting Korean wave contents abroad, contributing to Korean language education and cultural exchange, and becoming Korea's representative soft power factor through cultural event planning and international leadership. Through these roles, university students can gain opportunities to promote Korean culture and values to the world and form an international network, which has created a need for research on the lives of Korean university students. Method: In this study, 150 Korean university students were surveyed by convenience sampling method. A valid questionnaire was analyzed for 136 people, and the data were analyzed using the SPSS 23.0 program. Frequency analysis, t-test, and One Way ANOVA were used as analysis methods. According to the purpose of the analysis, differences in stress by gender, difference in organizational commitment by presence or absence of friends of the opposite sex, differences in empowerment by religious type, and differences in organizational commitment by friends of the opposite sex and dwelling type were explored. Results: First, as a result of examining the difference in stress according to gender in Korean university students, males answered Q7(I feel the need to reduce part of my role in my team) and Q8(I feel my role is too much in my team). It was found that women experience higher levels of stress than women. Second, as a result of verifying differences in empowerment according to religious types of Korean university students, in Q8(I decide the goal of my training by myself), the result was that Christian believers experienced higher empowerment than other religions(non-religious). And as a result of examining the difference in organizational commitment according to the presence or absence of friends of the opposite sex among Korean university students, those who have friends of the opposite sex were Q1(I feel a strong sense of belonging to the team I am currently training for), Q2(I think the current team is worth putting my heart and soul into), and Q3(I look forward to life in the team more positively in the future). Conclusion: First, Korean university students showed different role burdens and stress levels according to gender. Second, Christians tended to feel greater self-determination and control through religious values and belief systems. Third, those who have friends of the opposite sex tend to feel a strong sense of belonging and passion within the organization. Fourth, students living in university dormitory dormitories showed higher organizational commitment than students who commute to school. The university dormitory provides an environment that encourages the formation of relationships with classmates and communication with the outside world.

  • Purpose: This study proposes the Korea Coast Guard trainee behavior principle based on the value of the Korea Coast Guard in response to the Pandemic era. Through the proposed principle of action, we will provide philosophical standards for value judgment to members of the organization in various dilemma situations that Korea Coast Guard will face in the future. Recently, as a large number of young employees in various fields have been recruited in the Korea Coast Guard organizations, controversy has arisen due to the difference between the existing policies and the expectations of the younger generation. This means that the organization should make more efforts to establish and share the priority of organizational value to its members. Method: The Korea Coast Guard organizations have unique cultural characteristics that have been formed with unique history. This characteristic of the members is to examine the result of the formation of philosophical value of the Korea Coast Guard organization, along with the value policy of the Korea Coast Guard focusing on the educational regulations applied to the current students by the Korea Coast Guard Education Academy. As a research method of this paper, I would like to examine the behavior style required by members according to the unique characteristics of the Korea Coast Guard organizations in phenomenological aspects. The media press re-leases were used to maintain objective grounds among various problems caused by the characteristics of the Korea Coast Guard, and the internal voice of the organization was referred to the internal bulletin board of the Korea Coast Guard Agency. Results: As a conclusion of this study, based on the review of the philosophy and educational goals of the Korea Coast Guard organization. The principle of action is proposed 'Five Promises of Korea Coast Guard Students'. The proposed principle of student behavior is organized so that it can be applied to actual education center life from the perspective of the student. The first regulation of the prize and penalty for the students can be seen as a behavior that is supported and trusted by the people through 'honorable life' that helps others. Second, it emphazes that marine police will move toward a steady learning and effort as a guardian of the sea, along with the educational goal of 'trying to become an expert in the sea every moment' and prioritizing the expertise and practical skills. Third, the Coast Guard respect the human rights of the people who always keep their promises and do not follow injustice. Fourth, considering the spirit of public service value for the nation and the people that the result suitable for the public interest is more precious, overcoming the individual desire and discerning what is more suitable for the public interest is the value to be cultivated as a public official who serves the people after-ward, and above all, it can be wary of the situation that falls into the individualistic tendency, forgetting that he is a 'serviceman of the people'. Fifth, the direction of the challenge spirit shown in the 'expert in the ocean' that 'I am willing to challenge and overcome for a better future' and the future-oriented image that pursues the world's best pursued by educational goals can be confirmed. Conclusion: As such, this research suggests that the fundamental cause for this dilemmatic situation is on the absence of the values based on the organizational philosophies, and it is necessary for the organization to set up the operational methods based on its philosophical values taking into account the principles of action which are appropriate to the task of KCG(Korea Coast Guard). Also, this research asserts that the operation based on philosophical grounds contributes to the sequential positivity such as ‘psychological stability of the members’ and ‘creating hard working environments’ this will also help its members’ learning process and enhance the organization in general. The competence of KCG is the tool that leads to the safety, cleanliness and full of hope for our ocean. KCG has to possess the attitude that is challenging, creative and open that should be built upon its philosophical grounds for the long-term development of the organization. The result will be the achievement of public goods in the ocean and the safety of citizens.

  • Purpose: This study aims to examine the development direction of fire extinguishing education based on NCS on the teaching method of fire extinguishing education in the Navy. Fire extinguishment education is composed of basic education from basic remuneration to advanced education. Especially, since the Navy is mainly formed inside the ship composed of sealed compartments, fire extinguishing education is very important because there are such phenomena as Flameover, Backdraft, Flashover, Rollover, etc. except for special cases. And also, this study is focused on the fire extinguishing education for NCS-based education on beginner courses in the navy. Method: As a research method, the contents is developed focusing on literature review. At the same time, I work as a petty officer for 16 years and also consider the part that I actually experience as a field expert in the navy. Especially, I would like to propose an NCS-based education method that is used in most of the society in order to introduce the current fire extinguishment department in education and training. Results: In conclusion, the lecture-oriented education is still the most frequently conducted in our military. However, in order to promote the participation of learners through systematic education and training system based on NCS and job-specific education, which can be one of the field and lecture halls, and to apply it to the elementary fire-extinguishing education in the military, it is necessary to develop the NCS-based learning module together with the teaching and learning design and the teaching and learning process plan. Conclusion: Finally, the NCS learning module is designed to cultivate the ability to solve the job in case of exhibition or emergency. Therefore, it is effective for the students to diagnose the learning by preparing the result table and self-assessment checklist after the training and to perform grouping and individual practice according to the practice guide after the teacher provides the explanation and demonstration of the practice guide at the introduction of the class. In order to utilize the learning module effectively, teachers should thoroughly analyze the NCS to understand the contents and level of job ability required in the field work, and to have practical skills and expertise that can be used for performance evaluation. Especially, the new instructors should thoroughly analyze the contents of NCS related to the practical curriculum and prepare for the following matters in designing the teaching and learning process. The following research is to compare the satisfaction of NCS subject and NCS subject.

  • Purpose: Railroads are public transportation used by a large number of unspecified passengers, and the vehicle itself is large and very fast, so there is a lower probability of general accidents than road traffic, but once it occurs, it leads to a major accident, causing great human and property damage. In particular, high-speed railways running at 300km/h are obliged to realize the value of absolute safety, but in 2021, the number of high-speed rail-way accidents increased from 1 to 4 compared to the previous year, causing the reliability of railways to drop sharply. In order to prevent high-speed railway accidents through this, two aspects, primary accident prevention and secondary accident minimization, should be considered at the same time. Method: The study applied Heinrich's Law(Heinrich's Law), the principle of industrial safety, called the law of 1:29:300, in which dozens of minor accidents and hundreds of signs must appear before a major accident. In particular, it analyzed cases of high-speed railway accidents, which are major accidents among domestic railway accidents, and large-scale derailment accidents by overseas high-speed railway operators. One major accident is caused by hundreds of signs and repetitive and unconscious behaviors that cause the accident. Preemptive preventive measures are needed to prevent further major accidents from occurring on high-speed railways. Results: The causes of derailment accidents among high-speed train accidents in Korea were railroad workers' insensitivity to railway safety, lack of business cooperation between workers in different occupations, and lack of KORAIL safety management system. Overseas high-speed train accidents were derailment accidents in Germany, China, and France, which were also caused by railroad workers' ignorance and lack of safety management systems. In order for railway safety to become an absolute value, the need for train wireless protection was emphasized not only to preemptively prevent primary accidents but also to minimize secondary accidents. Conclusion: In this paper, train wireless protection devices were considered to prevent secondary accidents among railway safety fields. The train wireless protection devices warns other train engineers nearby to take emergency measures within a 2-4km radius when the engineer of the train presses the switch of the train protection device in the event of an emergency such as an accident during train operation. Railway accidents must continue to innovate the safety system for interfaces between sub-systems, so if train wireless protection devices are technically upgraded and systematic response algorithms are developed and applied to railway sites, it will be possible to block the "1" major accidents referred to in Heinrich's Law. In the future, empirical research on the con-tents of the study more requires experimental application considering the railway operation organization and operating environment.
