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.

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.
