Individuals with visual impairments face numerous challenges in their daily lives, with navigating streets and public spaces being particularly daunting. The inability to identify safe crossing locations and assess the feasibility of crossing significantly restricts their mobility and independence. Globally, an estimated 285 million people suffer from visual impairment, with 39 million categorized as blind and 246 million as visually impaired, according to the World Health Organization. In Saudi Arabia alone, there are approximately 159 thousand blind individuals, as per unofficial statistics. The profound impact of visual impairments on daily activities underscores the urgent need for solutions to improve mobility and enhance safety. This study aims to address this pressing issue by leveraging computer vision and deep learning techniques to enhance object detection capabilities. Two models were trained to detect objects: one focused on street crossing obstacles, and the other aimed to search for objects. The first model was trained on a dataset comprising 5283 images of road obstacles and traffic signals, annotated to create a labeled dataset. Subsequently, it was trained using the YOLOv8 and YOLOv5 models, with YOLOv5 achieving a satisfactory accuracy of 84%. The second model was trained on the COCO dataset using YOLOv5, yielding an impressive accuracy of 94%. By improving object detection capabilities through advanced technology, this research seeks to empower individuals with visual impairments, enhancing their mobility, independence, and overall quality of life.

The main aim of the current study is to examine the effects of mothers' parental beliefs and mother-child attachment on school-aged children's time management and life management skills through the mediation effects of children's self-regulation. Study participants included a total of 317 fifth- and sixth-grade children at elementary schools located in Seoul and Gyeong-gi area, and their 317 mothers. Children and mothers completed questionnaires and Structural Equation Modeling was adapted as the main analysis technique. The findings were the following: First, mothers' parental beliefs that emphasize the child's independence were significantly related to greater self-regulation ability in children, indicated by cognitive, motivational, and behavior regulation. Second, better quality of mother-child attachment perceived by children was also found to predict greater self-regulation in children. Third, children's self-regulation was strongly related to time and life management skills. When the child is better at self control, the child showed greater management skills, both in time and everyday life. Finally, as hypnotized, the test yielded a significant mediation effect of self-regulation in the association from mothers' parental beliefs and mother-child attachment to children's time and life management skills. The findings suggested the important role of parental beliefs about child rearing and attachment between mother and child in developing self-regulation and management skills of school-aged children.

The purpose of this study was to determine the relationship between activities of daily living and health-related quality of life in ambulatory stroke patients. This was a cross-sectional survey study of 60 patients who had survived one year or more after a stroke in community. Activities of daily living were assessed using the Functional Independence Measure (FlM) and health-related quality of life using the Stroke Impact Scale (SIS). The association between FIM and SIS was examined using Pearson' s correlation. The FIM score was higher than the SIS score. Most domains of FIM exhibited a high rate (45-85%) of ceiling effects. However, only the communication and memory domain of SIS exhibited of ceiling effects. The correlation coefficients were .835 (p<.01) for FIM-motor vs. SIS-ADL, .257 (p<,05) for FIM-motor vs. SIS-communication, .596 (p<.01) for FIM-motor vs. SIS-social participation, .635 (p<.01) for FIM-cognition vs. SIS-memory, .369 (p<.01) for FIM-cognition vs. SIS-ADL, and .289 (p<.05) for FlM-cognition vs. SIS-social participation. In conclusion, the correlation between FIM-motor and SIS-social participation was higher than that of FlM-cognition and SIS-social participation. The domains of emotion and hand function of SIS showed no correlation coefficients with FIM-total. To examine the activities of daily living and the quality of life in ambulatory stroke patients in community, it is necessary to use both the FIM and SIS.

Temperature has important effect on mechanical properties of wood. These effect needs to be understood and taken into account in the structural use of wood. Furthermore, the effect of cooling after exposing to high temperature must be explained. In this study, the effect of temperature, exposure time, specific gravity, and cooling on bending properties were investigated. The boundary temperatures at which bending MOE and MOR reduced rapidly were approximately $200^{\circ}C$ and $150^{\circ}C$, respectively. This boundary temperature was nearly constant with independence of species(specific gravity), exposure time, and cooling. Above the boundary temperature, the effect of exposure time was increased with temperature and the reduction of bending MOE and MOR for Japanese Larch with relatively higher specific gravity was smaller than that of Hem-fir. The recovery of bending MOE and MOR after cooling was also more significant above the boundary temperature than below. The degree of cooling effect was larger for MOR than MOE. Consequently, bending properties of wood in elevated temperatures should be considered in terms of the boundary temperature, $200^{\circ}C$ for bending MOE, $150^{\circ}C$ for MOR, and these boundary temperatures must be considered an important factor. Furthermore, to evaluate the safety of structure, the recovery after cooling should be considered.

The $1^{st}$ National Plan for Aging Society with Low Fertility, which the Korean government announced in 2006, caused the gradual increase of R&D investment in order to prepare for an aging society in Korea. This study explores if the directions and strategies of R&D projects related to aging are suitable to improve the quality of life for elderly people and establish a sustainable aging society by analyzing the features of R&D investment from 2004 to 2010. The results show that most R&D projects conducted by departments focus on the development of assistive devices for the elderly to support everyday lives. The Korean government's R&D policy to prepare for an aging society is based on the narrow interpretation of Quality of Life (QoL) in an aging society that tries to resolve the socioeconomic problems of the elderly; however, the policies have ignored the independence of active elderly individuals and the social integration of the young and elderly generations. The research shows that a paradigm shift is required from a 'Senior' to 'Aging Society' because almost 1/3 of the Korean population is over 65 years old and the expansion of the research embraces from assistive technologies for the elderly to the design of social infrastructure such as transportation, education and work.
