Contactless service is rapidly emerging as a new growth strategy due to consumers who are reluctant to the face-to-face situation in the global pandemic of coronavirus disease 2019 (COVID-19), and various technologies are being developed to support the fast-growing contactless service market. In particular, the restaurant industry is one of the most desperate industrial fields requiring technologies for contactless service, and the representative technical case should be a kiosk, which has the advantage of reducing labor costs for the restaurant owners and provides psychological relaxation and satisfaction to the customer. In this paper, we propose a solution to the restaurant's store operation through the unmanned kiosk using a state-of-the-art artificial intelligence (AI) technology of image recognition. Especially, for the products that do not have barcodes in bakeries, fresh foods (fruits, vegetables, etc.), and autonomous restaurants on highways, which cause increased labor costs and many hassles, our proposed system should be very useful. The proposed system recognizes products without barcodes on the ground of image-based AI algorithm technology and makes automatic payments. To test the proposed system feasibility, we established an AI vision system using a commercial camera and conducted an image recognition test by training object detection AI models using donut images. The proposed system has a self-learning system with mismatched information in operation. The self-learning AI technology allows us to upgrade the recognition performance continuously. We proposed a fully automated payment system with AI vision technology and showed system feasibility by the performance test. The system realizes contactless service for self-checkout in the restaurant business area and improves the cost-saving in managing human resources.
Our research participants were composed of health teachers exhausted by the COVID-19 pandemic. This study analyzed the attitudes towards image-making through utilizing the job training at Gwangju Metropolitan Office of Education on August 2022, where our study was able to obtain and analyze 30 elementary, middle, and high school health teachers who participated. Image making is defined as playing a role in increasing self-esteem through outward appearances such as facial expressions and posture, personal color, makeup, tone, hairstyling, and fashion and impacting individuals inwardly to increase self-confidence. Therefore, there is a positive impact in providing an image-making program that considers the occupational characteristics of a health teacher. It had the effect of stress relief and aided in building a healthier self-image among the participants. The results our study showed the following results. First, all participants had various concerns regarding their appearance and deemed that image-making was necessary, yet they needed to be more informed regarding the specific methods of doing so. Secondly, participants were mainly focused on purchasing makeup products for image making. Although participants showed interest in a personal color diagnosis, there needed to be more support in approaching the subject as the diagnosis was necessary from an expert. Third, participants stated that image-making should occur for their middle-aged selves when experienced in the field. Participants believed that they would be more concerned with how others viewed them after gaining expertise. Hence, this study found that the occupational characteristics of health teachers greatly benefitted from image-making programs oriented to their careers and would also show an increase in job satisfaction.
Due to the routine nature of social distancing in accordance with the COVID-19 pandemic, the logistics industry is under rapid development, given that offline demand is focused on online platforms. The number of warehouse workplaces and workers are steadily increasing per annum, and the industrial accident rate of transportation, warehouse, and telecommunication industries to which warehouse employees belong is higher than the total industrial accident rate in Korea. In previous studies, warehouse workers reported exposure to health hazards such as musculoskeletal disorders due to the handling of heavy objects and improper working postures. Accordingly, in this study, a survey was conducted to investigate symptoms of musculoskeletal disorders with focus on parcel delivery workers nationwide. The questionnaire included a musculoskeletal disorder symptom survey table to identify information such as worker occupational history, work type, and signs or symptoms of musculoskeletal disorders. Survey response data from 453 people were obtained to determine the influence of delivery business characteristics on occupational musculoskeletal disorders, and the influencing factors were analyzed. Based on the results, in the analysis of pain with respect to body part, the duration, degree, and frequency of pain were highest in the leg part, and as a result, the average value for the leg part exhibited a significant difference from those of other body parts. In addition, 52.32% of workers exhibited symptoms of musculoskeletal disorders, and a high number of patients with musculoskeletal disorders was observed in the work group with less than three years of service and with ages ranging from 30-39. The results of this study can serve as basic data for the derivation of a management plan that meets the characteristics of musculoskeletal disorders that impact logistics workers overburdened with work due to the rapid increase in parcel delivery volume in accordance with an increase in online consumption.
There has been an increase in the viewing of YouTube content among children and adolescents. This, coupled with the popularity of live-streamed video content such as mukbang, where viewers watch the host eat, has raised concerns about media addiction and the indiscriminate imitation of eating behavior. Therefore, there is a need for guidance on the appropriate behavior for viewing YouTube food content to promote healthy eating habits among children. In this study, we aimed to compare the patterns of the main caregivers and their children while viewing media and investigate the impact of viewing YouTube food content on the physical and mental health of the children. The findings suggest that active YouTube food content viewing by the main caregivers may reduce imitative behaviors due to passive media consumption by their children. This study provides valuable insights by comparing and analyzing the YouTube content viewing of the main caregivers and their children. The results can be used as a basis for the development of lifestyle-centered guidelines for children. However, it is important to note that this study was conducted during the coronavirus disease (COVID-19) pandemic when there was a significant increase in the use of media, which is limitation of the study.
The demand for non-contact service has increased a lot along with the development of technology and the generalization of social distancing to prevent COVID-19 spread during the pandemic. This study analyzed mediator and moderating variables between digital literacy and intention of continuous use of non-contact service were identified. The result showed that digital literacy had a significant influence on intention of continuous use of non-contact service. In particular, self-efficacy and satisfaction played a moderating role in the relation between digital literacy and intention of continuous use of non-contact service. This study is intended to contribute to expanding the base of non-contact service by verifying whether satisfaction and self-efficacy played important mediator variables in the relation between digital literacy and intention of continuous use of non-contact service

This study investigates the influence of particulate matter concentrations on the incidence of asthma, focusing on the delayed onset of symptoms and subsequent medical consultations. Analysis incorporates a four-day lag from the initiation of fine dust exposure and compares asthma patterns before and after the World Health Organization's (WHO) classification of fine dust as a Group 1 carcinogen in November 2013. Utilizing daily PM10 data and asthma-related medical visit counts in Seoul from 2008 to 2016, the study additionally incorporates Google search frequencies and newspaper article counts on fine dust to assess public awareness. Results reveal a surge in search frequencies and article publications after WHO announcement, indicating heightened public interest. To standardize the long-term asthma occurrence trend, the daily asthma patient numbers are ratio-adjusted based on annual averages. The analysis uncovers an increase in asthma medical visits 2 to 3 days after fine dust events. Additionally, greater public awareness of fine dust hazards correlates with a significant reduction in asthma occurrence after such events, even within 'normal' fine dust concentrations. Notably, behavioral changes, like limiting outdoor activities, contribute to this decrease. This study highlights the importance of analyzing accumulated medical data over an extended period to identify general public behavioral patterns, deviating from conventional survey methods in social sciences. Future research aims to extend data collection beyond 2016, exploring recent trends and considering the potential impact of decreased fine dust awareness amid the COVID-19 pandemic.

The untact environment brought about by the global pandemic has emerged as a new driving force for the matured social media market. In the post-coronavirus era, there arises a pivotal need for foundational data to reconfigure the operations and utilization strategies of social media. Using data from the 2022 Korean Media Panel Survey, this study compared sociodemographic and personality factors between social media non-users and users, and examined how these factors influenced social media usage time. The findings indicate differences between social media non-users and users in terms of gender, age, education level, income level, employment status, marital status, openness to experience, conscientiousness, extraversion, and neuroticism. Usage time of social media is influenced by gender, age, income level, employment status, conscientiousness, and agreeableness. These results are anticipated to enhance the understanding of users and their usage behaviors for stakeholders in the social media market as they confront a potential second leap forward.

Objectives: Many fields have changed since covid-19, psychotherapy being no exception. With the pandemic associated increase in untact treatment, interest in virtual reality exposure therapy has also increased. The aim of study was to analyze recent literature using virtual reality therapy for the treatment of anxiety disorders. Methods: We searched five databases from dates between October 1 to November 1, 2020. We selected articles related to the treatment of anxiety disorders using virtual reality therapy and analyzed the trend of that, not thesis but domestic articles. Results: There were 6 RCT studies and 3 were case reports where, based on the DSM-4, the participants presented with anxiety disorders including 2 with presentation anxiety, 1 heterosexual anxiety, 1 test anxiety, 1 social anxiety, 1 dental anxiety, 2 Acrophobia, and 1 social phobia. Treatment sessions varied from 1 session to 18 sessions, but 5 studies conducted 4 sessions, and all studies attempted virtual reality exposure for 30-minute time periods. 8 studies used HMD as the VR device and 1 study did not report a device. Conclusions: Anxiety disorders treated using virtual reality included speech anxiety and acrophobia. Median treatment session number was 4 and sessions were less than 30 minutes. The most common VR device used was an HMD. VR psychotherapy showed limitations relating to patient experience including cyber sickness and a lack of immersion. In addition, most of the studies were conducted with patients who visited hospitals utilizing Western medical practices. Currently, virtual reality therapy (VRT) intervention in oriental medicine is lacking. The lack of research in this area suggests analyzing data from VR psychotherapy in oriental medicine could provide novel and useful information.
It is undeniable that urban greenspace is the soul of a city. Conventional urban greenspace such as parks, community gardens, playgrounds etc. located within a city reduce the negative effects of pollution, play a major role in the survival of the urban ecosystem, and promote healthy lifestyles. Today, 55% of the world's population lives in urban areas, which is expected to increase to 68% by 2050. Projections show that urbanization and the gradual migration to urban areas combined with the fast growth of the world's population, could add another 2.5 billion people to urban areas by 2050 and almost 90% of this increase will take place in Asia(UN, 2018). As a result, many plots in the cities are and will continue to be occupied with buildings to provide residential support to the increased population. This will dangerously decrease urban greenspaces. Moreover, worldwide, food crisis, energy crisis, and social crisis is posing a great threat to the existence of mankind. Additionally, the COVID - 19 has introduced a new lifestyle where from work culture to community configuration has drastically transformed. In this scenario, residential buildings will have to serve more than just providing privacy and shelter. As urban greenspaces are being occupied by concrete residential buildings, these buildings will have to compensate for the percentage of urban green they are destroying and the issues they are imposing in the process. The goal of this thesis is to design, architecturally define and, categorize comprehensive 'sustainable Greenspace'(S.G.S) for the multi-family housing scenario. These will be different than the conventional green (veranda, rooftop green) we commonly see in residential buildings. An old, dilapidated apartment building will be the target of remodeling to fulfill the purpose of this thesis.
