The purpose of this study is to figure out problems and to suggest improvement scheme by examining 31 of the disabled who used power wheelchair developed for safe moving and standing support. The results are as follows. First, standing power wheelchair that enables the disabled to sit and stand up was developed. It can also be used as means of transportation for moving in narrow space and in a short distance. In the usability test of this prototype, two groups were respectively examined in 60 evaluation items. One group consisted of 16 people with disabilities using manual wheelchairs. And the other one consisted of 15 people with disabilities using automatic wheelchairs. The entire average figure of two groups was shown to be 2.72 and standard deviation was 0.820. Specifically, the average figure of the group in manual wheelchair was 2.85 and the one of the other group in automatic wheelchair was 2.57. And both group replied that the move to stand up and sit on both types of wheelchair was the most inconvenient thing. It shows why ergonomic design for persons with under extremity disabilities to stand up and sit is needed. Second, with further study based on the results of usability test of the disabled, it will make contribution to increase the quality of people with disabilities by helping them move and do daily lives on their own.

White light-emitting diodes (LEDs) are more economical than fluorescent lights, and provide high brightness, a high lifetime expectancy, and greater durability. As LEDs are closely connected with people's daily lives, dimming control of LED is an important component in providing energy savings and improving quality of life. In visible light communications systems using these LEDs, multiple input multiple output (MIMO) technology has attracted a lot of attention, in that it can attain the channel capacity in proportion to the number of antennas. This paper analyzes the power performance of three kinds of modulation in visible light communications (VLC) systems applied space-time block code (STBC) techniques. The modulation schemes are return-to-zero on-off keying (RZ-OOK), variable pulse position modulation (VPPM), and overlapping pulse position modulation (OPPM), and dimming control was applied. The power requirements and power consumption were used as metrics to compare the power efficiency in $2{\times}2$ STBC-VLC environments under the three kinds of modulation. We confirm that dimming control affects the communications performance of each modulation scheme. VPPM showed greater consumption among the three modulations, and OPPM showed energy savings comparable to VPPM.

New infectious diseases have broken out repeatedly across the world over the last 20 years; COVID-19 is causing drastic changes and damage to daily lives. Furthermore, as there is no denying that new epidemics will appear in the future, there is a continuous need to develop measures aimed towards responding to economic damage. Against this backdrop, the living population is an important indicator that shows changes in citizens' life patterns. This study analyzes time-based and socio-environmental characteristics by detecting and classifying changes in everyday life caused by COVID-19 from the perspective of the floating population. k-shape Clustering is used to classify living population data of each of the 424 dong's in Seoul measured by the hour; then by applying intervention analysis and One-way ANOVA, each cluster's characteristics and aspects of change in the living population occurring in the aftermath of COVID-19 are scrutinized. In conclusion, this study confirms each cluster's obvious characteristics in changes of population flows before and after the confirmation of coronavirus patients and distinguishes groups that reacted sensitively to the intervention times on the basis of COVID-related incidents from those that did not.

Care of people with severe disabilities requires care throughout their life cycle compared to non-disabled families. For this reason, carers of severely handicapped families are highly likely to have negative feelings throughout the family as well as daily stress. Disabled families also have a high rate of experiencing difficulties between non-disabled children or married couples in life centered on the disabled. In particular, the rapid aging in Korea affects the lives of the elderly disabilities along with the aging of the caregivers. The study explored alternatives to realistic support through the past and present experiences of caregivers with disabilities through qualitative research methods, and derived hopes and expectations for the future as follows.First, after confirming the disability for infants and toddlers with disabilities, information about the support system or system is provided from the rating agency. Second, providing "customized care support" suitable for the type of disability or individual characteristics at the social, political, institutional, and economic levels. Third, the provision of programs for non-disabled children and the provision of healing programs only for families with disabilities or those with disabilities. Fourth, the provision of spaces and programs that provide rest and rest for adults with disabilities. Fifth, the application of a long-term care system for the elderly reflecting the aging age of the disabled and institutionalization of community care for the disabled. The research is meaningful in that it presents discussion points for improving the quality of life of adults and the elderly with disabilities.

The purpose of this research is to examine So-Hak(小學) and Seodang(書堂) education, which were at the heart of child-adolescent education in Cho-Sun dynasty, and their implications on character education. In other words, this research is an attempt to review a traditional education from a modern character education perspective. So-Hak contains as major educational concepts Hyo(孝) and Kyeong(敬), guiding principles of daily lives. In this research, two basic concepts of So-Hak were reinterpreted from a modern perspective, namely, Soe-So-Eung-Dae-Jin-Tae(灑掃應對進退) and Ye-Ak-Sa-Eu-Seo-Su(禮樂射御書數). One of major implications of So-Hak lies on the habituation of what is learned, for habit leads to continuation of action, out of which the development of character emerges. As such, the role of habituation in character education is twofold, namely, basic educational content and method. Seodang is a school in which the teachings of So-Hak is realized. From an educational method perspective, Seodang's teaching-learning methods of reading, writing, and calligraphy methods were examined. As a result, three implications of So-Hak and Seodang were drawn, the habituation of what is learned, unification of knowledge and morality, and individualized learning based on one's own level.

In this paper, Han Yong-un's view point of Buddhism was examined in the traditional Zen Buddhism. He emphasized the essence of calm and awakened Zen in Wonhyo's theory of Jigwanssangun and Jinul's theory of Jeonghyessangsu. He criticized the behaviors of Zen priests at that time who turned their back on common people, secluded themselves in mountains and tried to stay calm in their places, and ideologically stressed that calm and awakened Zen should be realized in disciplinants' daily lives while enlightening the public. On the other hand, he had consistently stuck to Imjeseonpung(臨濟禪風) based on the spirit of saving the world, rather than depending on Jodongowi(曹洞 五位), when glossing "Sip-hyun-dam" with the traditional $S{\bar{o}}t{\bar{o}}$ Zen(曹洞宗) after Kim Si-seup Compared with Jodongowi, Siphyeondamjuhae(十玄談註解) emphasized Pyeonjungjeong (偏中正) where the right position(正位) of a true man(眞人) is founded in the middle of common people's partiality(偏位). In Siphyeondamjuhae, he intended to rebuke Japanese $S{\bar{o}}t{\bar{o}}$ Zen priests' brutality of trying to annihilate even the spirit of Zen Buddhism through Treaty of Alliance of Korea-Japan Buddhism(朝日佛敎同盟條約). Considering Han Yong-un's view point of Buddhism, it has the characteristic of patriotism and love of the people in the traditional Zen Buddhism.

This case study aimed to investigate changes in adolescents' awareness of the motivation behind their excessive internet gaming after group music psychotherapy. Five middle school students participated in six 60-minute group sessions over 4 weeks. The group music psychotherapy program was developed to help participants understand their implicit reasons for excessive internet gaming. Verbal responses were obtained from pre-program and post-program interviews and original lyrics created by participants during program were collected for analysis. Obtained data were analyzed in terms of emotional and cognitive aspects in relation to the participants' awareness of the motivation behind their excessive gaming. The results showed that song writing as creative musical process allowed participants to be aware of positive and negative influence of gaming on themselves and express their motivation to change their perception on gaming behavior. Also, the participants reported that the use of musical product for their daily lives could be an effective coping strategy to manage their gaming behaviors and an alternative for gaming. The findings from this study support that group music psychotherapy can be an effective approach to promote awareness of adolescents' motives for excessive internet gaming and to help adolescents better manage their gaming behaviors.

This study started from the question of what we think about big data as the term "big data" was used and discussed in our daily lives in the era of the 4th industrial revolution. For the analysis, the final 30 Q samples were selected based on prior research related to big data, and 23 respondents were secured for Q analysis, and the following results were derived. First, the explanatory power of each type was 34.30% for , 8.03% for , 7.21% for , and 6.24% for , showing a total of 55.69%. Second, the Q sample emphasized by respondents by each type shows various occupational distributions in , and for 'big data', it is 'digital' and future'. So they were named 「Digital Type」. In , the distribution of 'social workers' was high, and for 'big data', 'future', 'collaboration', 'welfare', 'local residents', and 'defense' were emphasized. It was named 「welfare type」. In , the job distribution of respondents appeared evenly, and it was named as 「Convergence Type」. Because it emphasized statements such as 'convergence', 'digital', 'future', and 'sports'. is composed of association officials, sports instructors, and graduate students, and was named 「Artificial Intelligence Type」, because it emphasizes 'artificial intelligence', 'new paradigm', 'network', and 'sports'. In the age of knowledge industrialization and knowledge informatization that followed industrialization and informatization, how to process and utilize the numerous data accumulated over the years is an important task. Right now, in sports, more than anything else, it is necessary to continuously seek ways to utilize and activate accumulated big data.

The COVID-19 pandemic reminded us again of the importance of essential workers who perform their roles in maintaining the stability of people's daily lives worldwide. Therefore, the International Maritime Organization and overseas countries designated seafarers as essential workers and proposed relevant measures for their protection to enable them to perform their role. In particular, the International Maritime Organization (IMO) urges related associations and member states to support safe boarding and disembarkation of seafarers. However, Seafarers were restricted from boarding or disembarking, shore leave and hospital treatment in certain countries owing to extreme nationalism. This study compares and analyzes the cases of international organizations and major overseas countries to provide a logical basis for the protection of seafarers who play an essential role in the safety of the global supply chain despite the COVID-19 pandemic. This study identifies the need to protect seafarers and their roles as essential workers in the shipping industry and suggests necessary aspects and institutional improvement measures for improving seafarers' working environment to strengthen the shipping industry's resilience. This study is expected to serve as future basic data for national policies aimed at reflecting the roles of seafarers as essential workers and the need to protect them.

This study aims to propose improvement plans and directions of existing policies to build a Barrier-Free city for the socially underprivileged. We conducted correlation analysis and T-test based on the results of a survey of the general public including the socially underprivileged to understand how their satisfaction with the use of facilities close to their daily lives, such as housing, sales·business facilities, affects their happiness. The results are as follows: First of all, the socially underprivileged experienced discomfort and barriers in urban life more than the privileged, and there was a negative(-) correlation between the degree of discomfort and barrier that the socially underprivileged experienced and happiness in urban life. Second, as a result of analyzing the difference in satisfaction with the life·welfare·leisure environment indicators, the satisfaction with the life environment showed a significant difference between the socially underprivileged and the privileged, and it was found that satisfaction in the life environment had the greatest effect on happiness to the socially underprivileged. We examined the current status and the spatial distribution of BF-certified facilities, one of the representative policies for the socially underprivileged to support their urban life without any obstacles, based on the above outcome, and most certified facilities were concentrated in welfare environment. In addition, we used ArcGIS to analyze that BF-certified facilities have been being supplied to people who really need them and saw that the spatial distribution of the socially underprivileged (elderly, children, and infant) and the distribution of BF certification facilities were somewhat consistent, but were intensively supplied to urban areas.
