Sound can travel a long distance in the ocean; hence, acoustic instruments have been widely used for ocean observations in various fields such as bathymetric survey, object detection, underwater communication, and current measurements. Herein we introduce a pressure-recording inverted echo sounder (PIES) which is one of the most powerful instruments, moored at seafloor for ocean observation in physical oceanography. The PIES can measure various kinds of oceanic phenomena (currents, mesoscale eddies, internal waves, and sea surface height variabilities) and support acoustic telemetry and pop-up data shuttle (PDS) system for remote data acquisition. In this paper, we review uses of PIES and describe present and prospective system of PIES including remote data acquisition toward (quasi) real-time data recovery.

This study explores and compares Korean and U.S. elementary preservice teachers' analytic approaches of students' addition and subtraction computational strategies. Twenty-six Korean and twenty U.S. elementary preservice teachers participated in the study. Participants were asked to analyze mathematical approaches and errors from students' addition and subtraction operations. Preservice teachers' written documents were analyzed by applying open coding and inductive coding based on the grounded theory. As a result, the pattern of error analysis and interpretation of students' addition computations were similar for both Korean and U.S. preservice teachers whereas there were some differences in the analysis of students' subtraction computations. Both Korean and U.S. preservice teachers had difficulties identifying students' strategies and errors for a complicated and unconventional computational approach. Results also indicated that preservice teachers' noticing and interpretation of students' strategies and errors were influenced by their K-12 mathematics curriculum and teacher education program. This study suggests implications and future directions for teacher education, more contextualized teacher preparation programs and balanced connection to the K-12 curriculum.

This is a descriptive research study to explore factors related to the perception of digital sex crimes among university students of the MZ generation in Korea. Data were collected by conducting a survey of 150 university students in Korea. As a result, the variable that showed the highest relevance to the recognition of digital sex crimes among MZ generation university students was sexual perception (β=-0.390, p<.001). Total explanatory power was 25.2% after adding gender (β=0.207, p=.018) and sexual attitude (β=0.157, p=.045). Our results suggest that customized education in consideration of factors related to digital sex crime perception is needed to form and improve a correct perception of digital sex crimes among MZ generation university students.

This study is a descriptive survey study for nurses in general hospitals to understand the effects of self-leadership, self-efficacy, and organizational commitment on safety management activities. The subjects of the study were nurses at three general hospitals located in G City. An online survey was conducted in consideration of the COVID-19 pandemic situation. Data collection was from August 20 to August 30, 2021. As a result of the study, self-leadership (r=.618, p<.001), self-efficacy (r=306, p<.001), organizational immersion (r=0518, p<.001) showed a positive correlation with safety management activities. In addition, self-leadership, self-efficacy, and organizational commitment explained 38.2% of safety management activities (F=20.478, p<.001). Therefore, it would be helpful to provide regular leadership education and self-efficacy education to increase patient management activities of general hospital nurses. In addition, if a positive work environment, legal standards for nurse work, and an appropriate compensation system are established to improve organizational commitment, it will have a positive effect on environmental safety management activities.

Aging is a complex biological process characterized by a gradual decline in cellular and physiological functions. This natural process is associated with age-related diseases, including Alzheimer's disease, atherosclerosis, and hypogonadism, which are significant health concerns among older individuals and can significantly impact their quality of life. Researchers have found that epigenetic markers play a crucial role in regulating aging and age-related diseases. Epigenetic markers are heritable gene expression alterations that do not change in the DNA sequence. This review focuses on the involvement of various epigenetic marks, such as RNA methylation, DNA methylation, and microRNAs (miRNAs), in regulating gene expression patterns associated with age-related diseases, such as Alzheimer's disease, atherosclerosis, and hypogonadism. These epigenetic alterations can lead to the dysregulation of specific genes and signaling pathways, contributing to the development and progression of Alzheimer's disease, atherosclerosis, and hypogonadism. Understanding the molecular mechanisms behind these epigenetic modifications is essential for both the aging population and individuals seeking ways to promote overall well-being. By gaining deeper insights into how epigenetic marker alteration occurs during aging and age-related diseases, researchers can potentially develop targeted therapeutic strategies to alleviate the impact of these conditions and improve the quality of life for older individuals.

El cine como medio de narrar el trauma histórico de los cubanos se formó especialmente en los años sesenta gracias al Instituto Cubano del Arte e Industria Cinematográficos y se sitúa en la cumbre. En el cine hecho por el director cubano Humberto Solás el discurso de historia, trauma y su memoria tiende a relatar básicamente sobre el mensaje de no olvidar el trauma histórico a través de buscar la manera eficaz e intrínseca de narrarlo. El hecho de no olvidar el trauma histórico y de poder enfrentarse con los elementos causantes del trauma significa el poder de tener la posibilidad probable de adquirir la mirada objetiva para observar la experiencia 'histórica' y la memoria 'cotidiana', y sus relaciones. Si consideramos el hecho de que la tendencia de la víctima suele querer olvidar la memoria del trauma por el miedo y dolor de enfrentarse con la representación del trauma, el enfrentarse con el trauma representado ya puede significar que la víctima esté en un trámite de conseguir la penetración con la cual supera lo negativo que le ofrece el trauma a la víctima. Este artículo se dedica especialmente para averiguar la estrategia del director cubano para realizar este fin de encontrar la manera adecuada en narrar el trauma cubano para que los cubanos puedan adquirir la penetración a través de la identificación y la simpatía entre los personajes del cine y los espectadores, enfocando con detalle en los carácteres de los protagonistas femeninas que son tres diferentes individuos en el mismo número de episodios. Cada protagonista, Lucía en cada episodio experimenta el trauma personal con diversos motivos, pero a pesar del dolor y del miedo del trauma histórico se despiertan los espectadores, quienes se identifican con la protagonista a través de la simpatía y la identificación, llegándose al momento de conseguir la penetración con la cual mira el futuro de la sociedad cubana con el objetivismo libre de los traumas históricos.
