As multidisciplinary marine research is actively conducted, various types of marine research facilities and equipment are purchased every year. However, among marine research facilities and equipment, it is difficult to classify and manage various types of field observation equipment used for environmental data collection and sample collection under the current national research facility and equipment standard classification system. In the case of Korea Institute of Ocean Science and Technology, about 30% of research facilities and equipment are unclassified and not properly managed. In this study, marine research facilities and equipment are classified into 7 middle and 36 sub-classes according to their characteristics. It is proposed to add a large classification group called 'Environmental Observation/Analysis Equipment', to the national research facility equipment standard classification system. In addition, it is proposed to classify the equipment operated in the laboratory among marine research facilities and equipment according to the existing national research facility equipment standard classification system. Through this, it is expected that all of Korea's marine-related research facilities and equipment can be systematically classified and managed effectively.

Marine debris not only affects the survival of marine life, water pollution, and scenery but also has secondary effects on economic loss and human health. While research on underwater and surface debris is actively ongoing, solutions to marine debris in hard-to-reach blind spots are being developed slowly. To address this problem, we utilize drones to detect and track marine debris in blind spots such as tetrapods. The detected debris is then visualized by calculating its location coordinates using the drone's GPS, altitude, and heading values. The proposed method of using drones for detecting marine debris and matching it with longitude and latitude coordinates provides an effective solution to the problem of marine debris in blind spots.

This study analyzes the characteristics of the social value creation process through the collective appreciation of film. It focuses on the historical development of community cinema in Japan. In modern-day Japan, where digital video is easily accessible and the use of private, personalized media spaces widespread, a sub-culture of collective film appreciation is spreading, as more and more Japanese begin to attend movie screenings in non-commercial theaters. In addition, Japanese community cinema center has begun to integrate and support this viewing experience, which has come to be known as community cinema. A literature review revealed the following characteristics of community cinema. First, local theater screening groups or appreciation groups cooperate with residents to establish and operate movie theaters. Second, these spaces create theoretical and practical participatory learning opportunities that foster understanding of and participation in film culture, through large-scale associations with organizations or institutions that offer viewings. Third, based on collective appreciation, the film culture created through repeated joint viewings produces a social arena in which community can be realized. In these communities film can be put to socially productive uses, such as problem solving.

This study aims to analyze both the current utilization of e-learning in the scuba diving education sector and the possible improvements by using Delphi analysis. The study administered three rounds of Delphi surveys with 25 specialists, including business executives and educational leaders from scuba diving centers and resorts affiliated with organizations that conduct scuba diving education through e-learning. The comparative analysis of the state of e-learning utilization and factors for improvement revealed significant insights. In terms of expected benefits, the analysis highlighted an increase in user convenience, temporal flexibility in learning activities, and easy access to products. However, it identified major issues such as the simplistic mandatory exams, inadequate professional depth in the feedback provided, and a lack of bidirectional communication between learners and instructors. Recommendations for improvements included enhancing communication through various online communities, conducting mandatory exams offline, and developing a variety of content. Conducting regular program quality evaluations, integrating with various diving communities, and assigning dedicated tutors were deemed crucial factors for future development.

Oil and gas contribute significantly to achieving the growing demand for energy, which is rising in parallel with population growth. The pipeline system is the main transport system used in the distribution of oil and gas because the pipeline system is considered the most effective and efficient system. The distribution system for gas and oil must guarantee security and safety. Analyzing the pipeline is necessary to ensure distribution security and safety. In this study, a finite element analysis of the gas pipeline specimen was conducted. This analysis is carried out in two stages, first structural analysis and continued with damage analysis, where the damage used is a dent. In the dent analysis, environmental conditions are applied, namely non-pressure, pressure, and full pressure. Then assessed all the results of the analysis of each stage, the assessment was carried out by verifying the results of the analysis with the applicable standard rules. So that the characteristics of the pipeline can be recognized and work accidents caused by operating pipeline failure can be avoided.

This study set out from the perception that one should develop and activate differentiated programs from those 5 programs of the Health Family Support Center (family counseling program, family education support project, family affinity culture support project, care support project, diversity family support project) on the subjects (n=299) of residents in G metropolitan city by reflecting the levels of family values, communication between family members and family relationship. To achieve the study purposes above, this study devised research questions as follows: Research question 1. What are the levels of local residents for their family values, communication between family members and family relationship? Research question 2. Is there any difference in demanding family support project programs according to the local residents' family values, communication between family members and family relationship? Following are the results of this study: First, the levels were analyzed to be more than the average (on a maximum scale of 5 points) with local residents' family values (M=3.55, S.D.=.664), communication between family members (M=3.65, S.D.=.669), family relationship (M=3.69 S.D=.584) Second, the necessity levels for family values, communication between family members and family relationship of the group below the average as compared with the group over the average was found to be significantly high in family education support project, family affinity culture support project, care support project and diversity family support project except family counseling program. Accordingly, strategic plans for increasing the participation rate for the programs by the Health Family Support Center and activating those programs could be by investigating in advance the levels of family values, communication between family members and family relationship by each program respectively and differentiating the target level for the program by the group, or by giving preference to the group below the average who have high needs of program necessity when making decisions for the participation preference of the programs.
