This study was to examine the relationship between suicidal ideation, depression, stress and their parent's socioeconomic status. Nation-wide representative data from the Korean National Health and Nutrition Examination Survey 2009 were used in this study. 904 adolescents with parent were analysed. Parent's socioeconomic status, especially mother's low educational level and the beneficiaries for national basic livelihood security were significant risk factor for adolescents' suicidal ideation. These associations remained significant in multiple logistic regression controlling for all covariates. The findings in the current study support the global literature on the importance of socioeconomic status in promoting adolescent's mental health. Future prevention intervention efforts to improve adolescent's suicide risk will need to take into consideration parent's and household's socioeconomic conditions. Future study is needed to explore the possible proximal risk factors and mediators between parent's socioeconomic status and mental health among adolescents.

The objective of this research was to assess the reliability of data and to improve nuclear analytical techniques concerning the Domestic Radioactivity Intercomparison program for environmental radioactivity monitoring of Jeju from 1998 to 2006. Gross beta for filter papers and water samples was determined, and gamma nuclides for natural and artificial nuclides in soil and water samples were analyzed. The gross beta activity of all samples except for the water samples of 1998 and 1999 showed a good agreement within the confidence intervals. In gamma nuclides, $^{40}K$ and $^{137}Cs$ of soil samples and most nuclides in the water samples, with the exception of several nuclides, were evaluated to be reliable. Based on these results, it is considered that a reliable method for the analysis and monitoring of environmental radioactivity were established, which may play an important role in case of emergency radiation accident.

If we were in a head-on or crossing situation with a target ship and did not know the target ship's intention to change her course, we might be confused about our decision making to change our course for collision avoidance and be in a danger of collision. In order to solve these problems, we need to develop an automatic system which enables mariners to easily detect a change in the target ship's course and efficiently avoid being on a collision course. In this paper, we proposed an early detection method on altering course of a target ship using the steering wheel signal. This method will contribute to the reduction of collision accidents and also be used to the VTS system and the analysis of marine accidents.

This paper describes a short-term prediction model for the movement of an oil slick in shallow waters. Under the assumption that the initial movement of the oil slick is governed by spreading and advection, the model has been developed and applied to Kyungki-Bay near Incheon Harbor. The initial spreading is estimated by using an empirical formula. The depth-averaged momentum equations are solved numerically for the volume transport velocities, in which the $M_2$ tide is the main driving source. A staggered grid system is adopted fur spatial discretization and the half-time method is implemented for time marching. The numerical result is visualized with the help of animation and thus the contaminated area is displayed on a monitor in time sequence. The input data are the time, the location and the volume of spill accident as well as environmental data such as md and $M_2$ tide.

Detection of crosswalk is an important issue for the blind to walk without the help of others. There is a braille block on the sidewalk, which helps the blind to walk. On the other hand, crosswalk is more dangerous due to the moving vehicles. However, there is no appropriate means to induce the blind. In this paper, we propose a method to detect crosswalk in front of a blind and estimate its direction using an image sensor. We adopt multi-ROIs and make their binary versions. In order to determine whether it is a crosswalk, two features are extracted; one is the number of crossing in the binary image and the other is the ratio of white area. We can also estimate the direction of the crosswalk through the slope of the projection data. We evaluated the performance using experimental dataset and the proposed algorithm showed 80% accuracy of detection.

This study is to criticize whether festivals as cultural activities form cultural values by questioning about the animal cruelty in Korean festivals. Changes in the social awareness of animals and the viewpoint that shifted from human-centered thinking to values of the environment and life served as an opportunity to look back on animals. This study looked at festivals using animals in Korea and especially analyzed the four major animal festivals that have been criticized. A qualitative study method interpreting opinions, evaluations, alternatives, and arguments of cultural tourism and animal rights experts was implemented by conducting interviews with experts of cultural tourism and animal rights, who have conflicting views about animal festivals. The primary topic of discussion is a sharp criticism that 'sales of products based on innocence' is a commercialized cultural value. The expression that 'wrongful traditions do not need to be protected' is an escape from the customary memory of traditions that do not create cultural values. The act of stopping the long malpractice of traditional animal violence is the very act of creating 'cultural values.'

The purpose of this study is to explore the current status and effects of online discussion classes in universities. To this end, a survey was conducted on university students attending a total of four universities in Seoul and Gyeonggi Province to diagnose their perceptions of the operation of online discussion classes and their effects. The collected data were analyzed using frequency analysis, descriptive statistical analysis, cross-analysis, F-test, T-test, and Scheffe test by applying SPSS program. As a result of the study, first, it was found that 'non-real-time recorded lessons' and 'real-time interactive video lessons' were mainly conducted at universities after the COVID19 crisis. Second, in the online class method, 'real-time interactive video class' had a positive effect on 'debate class preference' and was found to be more meaningful. Third, college students recognized participation in online discussion classes as a foundation for expanding creative thinking skills, suggesting that strengthening through smooth communication and exchanges based on learners' sufficient cognitive processes on discussion methods and procedures is more helpful.

The increasing use of personal mobility has led to a rise in traffic accidents and social issues. Consequently, the government is continually revising laws and regulations to address the problems associated with personal mobility. This study conducted a survey that reflects user characteristics and public perceptions based on the law revised in May 2021. The personal characteristics, legal awareness, usage patterns, risk characteristics, and risk factors were analyzed. The analysis indicated that driving on roads without separate sidewalks, speeding, and carrying passengers are hazardous practices. Moreover, Poor awareness of the legal framework governing personal mobility results in law violations. These results are significant as they highlight the need for policy measures regarding institutional and legal improvements, and they underscore the importance of enhancing social awareness about safety as personal mobility become more widespread.

Narratives are fundamental to human cognition and social culture, serving as the primary means by which individuals and societies construct meaning, share experiences, and convey cultural and moral values. The field of artificial intelligence, which seeks to mimic human thought and behavior, has long studied story generation and story understanding, and today's Large Language Models are demonstrating remarkable narrative capabilities based on advances in natural language processing. This situation raises a variety of changes and new issues, but a comprehensive discussion of them is hard to find. This paper aims to provide a holistic view of the current state and future changes by exploring the intersections and interactions of human and AI narrative intelligence. This paper begins with a review of multidisciplinary research on the intrinsic relationship between humans and narrative, represented by the term Homo narrans, and then provide a historical overview of how narrative has been studied in the field of AI. This paper then explore the possibilities and limitations of narrative intelligence as revealed by today's Large Language Models, and present three philosophical challenges for understanding the implications of AI with narrative intelligence.
