This study sought to explore the enhancement of the introduction of teaching and learning methods for Problem Based Learning (PBL) and the evaluation factors to evaluate them effectively through an understanding lecture in Cultural Content Planning. It was intended to incorporate a practical zero-volume education methodology of problem-oriented learning and sufficient leading learning to reflect storytelling in the entire process of completing a cultural content with culture, cultural content, and content planning. To this end, the role of teaching methods should be faithful to ensure that teamwork and cooperation can be done organically according to the educational field, practice and situation. Students who take classes were asked to meet demand, reflect it through surveys, apply real-world problems, and acquire the entire course. Learners had to cooperate with each other until planning cultural content and completing the results through classes, and they evaluated themselves and colleagues in teamwork until the last result was completed from creative ideas. The results were shared together and the students were able to investigate the necessary PBL evaluation factors for themselves, and the prior research and survey on the method of PBL evaluation was conducted to derive the factors of understanding of cultural content planning. The derived assessment elements were able to identify priorities between the assessment elements using basic statistics, word cloud analysis, and AHP analysis. The components of the assessment derived were communication skills, basic knowledge, reasoning process, expertise, and evaluation techniques. Through this article, I was able to lead the understanding of cultural content planning to problem-oriented learning classes and encourage students to be familiar and smooth.

In a previous study, technology protection levels were set on a qualitative basis. That study lacked quantitative standards, so here, we conduct a study to complement the previous study and to present an objective standard. This paper provides a method of setting a technical protection level that applies statistical analysis. To set the technology protection level, statistical analysis of six technical survey items is performed first. Second, the technical survey items are analyzed by AHP to quantify the opinions of experts in order to derive weights for each technical survey item. Finally, by using the normal distribution scatter map and median calculation method, the technology protection level is selected in three stages using the final detailed factor technology score reflecting the weight. The technology protection level methodology developed through this study is the first methodology with objectivity that can evaluate defense technology by level. If this methodology is applied in practice, it is believed that it will provide a scientific and quantitative technology value judgment criterion when setting the technology protection level in the future.

This study intends to verify the effectiveness of incentive schemes at Busan Port' aimed at promoting transshipment cargo. The current incentive schemes of Busan port intended to increase the T/S cargo volume have been disputed constantly. It is imperative, therefore, to restructure the system in accordance with the planned strategy. In this study, in order to ensure objectivity of the incentive schemes, all the parties (carriers, terminal operators and Port Authority) with a direct interest are answered and analyzed using the AHP methodology. Effectiveness is the top priority in the analysis of beneficiary validity of incentive schemes, when incentives are provided to Global overseas carriers compared with Global national carriers, IntraAsia carriers and Terminal operators. In the analysis of incentive schemes, direct cash support corresponding to the quantity of the T/S cargo had the highest effectiveness compared with exemption of port dues, cost compensation, port infrastructure support and subsidy for the service opening. The study results, therefore, reference the Port Authority when restructuring the schemes. This study has been conducted only focusing on the Busan port; however, the findings may have significant implications for overseas Port Authorities intending to implement incentive systems to promote cargo volumes similar to those at Busan port.

There is a growing demand for the stability of existing dams due to abnormal climate and the aging of dams. Emergency Action Plans (EAPs) for reservoir or dam failure only consider a single rainfall event. Therefore, this study simulates dam failure caused by continuous rainfall events, and proposes the establishment of EAP by selecting the optimal shelters. We define a mega rainfall event scenario caused by continuous rainfall events with 500-year frequency in the Chungju Dam watershed and estimate the mega flood. The mega flood event scenario is divided into two cases: scenario A represents the flooding case caused by discharge release from a dam, while scenario B is the case of a dam break. As a result of flood inundation analysis, the flooded damage area by the scenario A is 50.06 km² and the area by the scenario B is 6.1 times of scenario A (307.45 km²). We select optimal shelters for each administrative region in the city of Chungju, which has the highest inundation rate in the urban area. Seven shelter evaluation indicators from domestic and foreign shelter selection criteria are chosen, and Analytical Hierarchy Process (AHP) method is used to evaluate the alternatives. As a result of the optimal shelter selection, the six shelters are selected and five are schools. This study considers continuous rainfall events for inundation analysis and selection of optimal shelters. Also, the results of this study could be used as a reference for establishment of the EAP.

Maritime transportation is one of the oldest means of transportation utilized by mankind, and it has significantly contributed to the advancement of civilization by efficiently transporting bulk cargo at a low cost. The study aim to identify the factors influencing the selection of shipping companies in the bulk shipping market and provide insights for improving the competitiveness of shipping-related companies. To achieve this goal, the Analytic Hierarchy Process (AHP) was employed. For the empirical analysis, previous research, interviews, and a pilot test were conducted to identify five top-level factors such as companies, vessels, operations, services, and transaction factors. Each top-level factor has four sub-factors. The results of the analysis, based on 80 valid questionnaires, are as follows: Firstly, in the selection of shipping companies, the priority of factors influencing the choice of shipping companies was as follows: vessel factors were the most important, followed by company, operations, relationship, and service factors. Secondly, when investigating the priority of sub-factors, the availability/appropriateness of vessels was the most crucial factor, followed by company characteristics, financial soundness, and the company's reputation in order. The implications of these findings suggest that shipowners should focus on securing more suitable vessels and enhancing their reputation in response to shippers' demand. Shippers, on the other hand, should consider maintaining a healthy financial structure as a crucial task in securing competitive shipping service providers.

The adoption of smart factories and smart manufacturing as strategies to enhance competitiveness and stimulate growth in the manufacturing sector is vital for a country's future competitiveness and industrial transformation. The government has consistently pursued smart manufacturing innovation policies starting with the Manufacturing Innovation 3.0 strategy in the Ministry of Industry. This study aims to identify policy areas for smart factories and smart manufacturing based on technical standards. Analyzing policy areas at the current stage where the establishment and support of domestic standards aligning with international technical standards are required is crucial. By prioritizing smart manufacturing process areas within the industry, policymakers can make well-informed decisions to advance smart manufacturing without blindly following international standardization in already well-established areas. To achieve this, the study utilizes a hierarchical analysis method including expert interviews and importance-performance analysis for the five major process areas. The findings underscore the importance of proactive participation in standardization for emerging technologies, such as data and security, instead of solely focusing on areas with extensive international standardization. Additionally, policymakers need to consider carbon emissions, energy costs, and global environmental challenges to address international trends in export and digital trade effectively.

This study aimed to examine the effects of leisure activities on leisure satisfaction and job satisfaction among airline cabin crew, as well as the mediating effect of leisure satisfaction. The context for this research was the sudden increase in air travel demand in 2022 following the COVID-19 economic recovery, which led to cabin crew members experiencing severe stress and fatigue due to excessive scheduling. To achieve this research objective, a self-administered online survey was conducted with 251 cabin crew members from domestic and international airlines, resulting in a total of 224 valid leisure satisfaction and job satisfaction, as well as the mediating effect of leisure satisfaction on the relationship between leisure activity types and job satisfaction. The hypothesis testing results revealed that all types of leisure activities, including family-oriented, friend-oriented, and work-related activities, had a significant positive effect on leisure satisfaction. Family-oriented and work-related leisure activities had a significant positive effect on job satisfaction, and leisure satisfaction had a significant positive effect on job satisfaction. Additionally, the mediation analysis confirmed that leisure satisfaction partially mediated the relationship between family-oriented and work-related leisure activities and job satisfaction, while it fully mediated the relationship between friend-oriented leisure activities and job satisfaction. Therefore, the study offers academic implications based on these findings and proposes strategies for utilizing various types of leisure activities to enhance leisure satisfaction and job satisfaction among airline cabin crew. It also suggests that future research should further validate these findings through methods such as the Delphi technique or Analytic Hierarchy Process (AHP) analysis to assess the importance and prioritization of these factors among relevant industry stakeholders.

Korea has studied FTA over 20 years since FTA with Chile. More than 3,000 Articles have been published in journal so far. Thus, this study aims to present the direction that should be taken by Korean FTA study by using Meta-Analysis for FTA study which has been carried on so far. Many researchers publish several articles each year, showing high quotation index and H-index. However, Korean FTA study lacks network with overseas researchers and fusion study with other sciences. 65.4% of Korean FTA study is carried on Independent research and 91.1% of them, in joint research by fewer than 2 persons. Further, the Subject of FTA study is not diverse and too uniform. Out of total studies, 24.3% of them are related to rules of origin and 15.3% of them, to China, showing that theme of study is quite partially concentrated. This is large difference with overseas FTA study. Study on rules of origin is only 1.5% in overseas. Korean FTA study needs to diversify subjects of study and to balance between academic aspect & practical aspect. When it comes to study methodology empirical analysis assumed large portion in both Korea and overseas countries. Empirical analysis assumes 18.3% in Korea and 47.3% in overseas, both of which are quite high. However, qualitative study such as FGI/AHP, in-depth interview, case analysis is quite rare in Korean FTA study. Partial concentration of countries for study subject needs to be rectified also. In Korea, countries for FTA study is China 15.3%, EU 10.0%, USA 6.3%. In overseas, China assumes only 3.7% of study subject. It is required for Korean FTA study to extend study subjects & study area by forming global study network and to extend qualitative study with microscopic study.
