The purpose of this study was to develop a smartphone based voice therapy program for patients with voice disorders. Contents of voice therapy were collected through analysis of mobile contents related to voice therapy in Korea, experts and users' demand survey, and the program was developed using Android Studio. Content needed for voice therapy was collected through analysis of mobile contents related to voice therapy. The user satisfaction evaluation for application was conducted for five patient with functional voice disorders. The results showed that the mobile contents related to voice therapy in Korea were mostly related to breathing, followed by voice and singing, but only 13 applications were practically practiced for voice therapy. Expert and user demand surveys showed that the patients and therapists both had a high need for content that could provide voice training in places other than the treatment room. Based on this analysis, 'Home Voice Trainer', an smartphone based voice therapy program, was developed. Home Voice Trainer is an application for voice therapy and management based on Android smartphones. It is designed to train voice therapy activities at home that have been trained offline. In addition, the records of voice training of patients were managed online so that patients can maintain voice improvement through continuous voice consulting even after the end of voice therapy. User evaluations show that patients are satisfied with the difficulty and content of voice therapy programs provided by home voice trainers, but lack of a portion of user interface, such as the portion of home button and interface between screens. Further study suggests the clinical application of home voice trainer to the patients with voice disorders. It is expected that the development study and the clinical application of smart contents related to voice therapy will be actively conducted.

Purpose: This research is to investigate factors that affect dental aesthetics and analyze whether individual perception affects and difference of genders affects the esthetic factors. Materials and methods: Seventy dental students of Chonnam University aged from 25 to 35 years old without periodontal problems were included. Maxillary dental cast for participants were made, and standardized photo was taken with a digital camera. Maximum visual width and the position of gingival zenith of maxillary anterior teeth and maximum height of the maxillary central incisors were measured by a measurement program and the shape of central incisor was categorized. Questionnaire was conducted to evaluate esthetic perception. SPSS program was used to perform statistical analysis. Results: The average visual width ratio of right maxillary anteriors was 1.38:1:0.78 and 1.41:1:0.81 for the left which differ from the golden ratio. The width to height ratio for right and left central incisor was 0.84 and 0.83 respectively. The gingival zenith position was determined to be: mostly, central incisors and canines were located in the distal side, lateral incisors were located in the center. The visual width ratio of right maxillary anterior teeth, ratio of width to height of central incisor, gingival zenith position, crown morphology and amounts of gingival exposure upon smiling were not significantly different between genders, and facial patterns and these dental esthetic factors were not related to aesthetic perception. Conclusion: Even though participants had the visual width ratio of maxillary anteriors or ideal width to ideal height of central incisors that did not agree with the golden ratio, they had high satisfaction for dental esthetics. Esthetic perception depends more on subjective judgements of participants than objective indices.

Since June 2006, there have been active efforts to systematize the permission system including the amendment of [Cultural Heritage Protection Act]. Cultural Heritage Administration prepared standards on reviewing each type of cultural heritages(CH) in 2015, promoted a project on the modification of permission standards and showed remarkable performances in quantitative aspects. But as there has been little change for the cases applied for permission, additional studies on policy are required to improve the management efficiency and reduce the citizens'inconvenience. In response, this study aims to identify the actual management status on the current state alteration permission system, and establish practically utilizable reference materials at permission review. While historic sites(HS) constitute a relatively small proportion in state-designated CHs, they are subject to the designation of permission standards. Also, with their location in the downtown area, the application rate is high (51.4%) and the results are commonly utilizable to other types of CH. We constructed a DB based on the minutes of Cultural Heritage Committee(CHC) on HS and categorized similar features in permission handling results. The result of the analysis is as follows. Out of a total of 5,243 cases for permission applied for HS, 1,734 cases of cultural heritage areas(CHA) and 3,509 cases of historic and cultural environment preservation areas(HCEPA) have been applied. CHA has a great proportion of the applications for events and festivals, which are highly related to CHs or representing the local area. There is a high permission rate on applications for the purpose of public service by local governments. Meanwhile, HCEPA has a high proportion of applying for the installation and extension of buildings and facilities at the private level. Thus, negative decisions were made for tall buildings, massed facilities, or suspected scattering of similar acts. Our actual condition analysis has identified a total of 78 types of harmful acts which may influence the preservation of CHs. 31 types in CHA and 37 types in HCEPA are categorized. Especially, 10 common types of permission have been confirmed in both sectors. As a result, it is expected to secure consistency in the permission administration, enhance the management efficiency and improve the public's satisfaction over the regulatory administration by providing practically utilizable reference materials for altering the current state of CH and for decision making on the part of CHC.

The study aims to grasp the perception and appraisal of urban park users through text analysis. This study used Google review data provided by Google Maps. Google Maps Review is an online review platform that provides information evaluating locations through social media and provides an understanding of locations from the perspective of general reviewers and regional guides who are registered as members of Google Maps. The study determined if the Google Maps Reviews were useful for extracting meaningful information about the user perceptions and appraisals for parks management plans. The study chose three urban parks in Seoul, South Korea; Seoul Forest, Boramae Park, and Olympic Park. Review data for each of these three parks were collected via web crawling using Python. Through text analysis, the keywords and network structure characteristics for each park were analyzed. The text was analyzed, as were park ratings, and the analysis compared the reviews of residents and foreign tourists. The common keywords found in the review comments for the three parks were "walking", "bicycle", "rest" and "picnic" for activities, "family", "child" and "dogs" for accompanying types, and "playground" and "walking trail" for park facilities. Looking at the characteristics of each park, Seoul Forest shows many outdoor activities based on nature, while the lack of parking spaces and congestion on weekends negatively impacted users. Boramae Park has the appearance of a city park, with various facilities providing numerous activities, but reviewers often cited the park's complexity and the negative aspects in terms of dog walking groups. At Olympic Park, large-scale complex facilities and cultural events were frequently mentioned, emphasizing its entertainment functions. Google Maps Review can function as useful data to identify parks' overall users' experiences and general feelings. Compared to data from other social media sites, Google Maps Review's data provides ratings and understanding factors, including user satisfaction and dissatisfaction.

The purpose of this study is to analyze the usage behavior of Seoullo 7017, the first public garden in Korea, to understand the usage status by analyzing blogs, and to present usage behavior and improvement plans for Seoullo 7017. From June 2017 to May 2020, after Seoullo 7017 was open to citizens, character data containing 'Seoullo 7017' in the title and contents of NAVER and·DAUM blogs were converted to text mining and socialization, a Big Data technique. The analysis was conducted using social network analysis. The summary of the research results is as follows. First of all, the ratio of men and women searching for Seoullo 7017 online is similar, and the regions that searched most are in the order of Seoul and Gyeonggi, and those in their 40s and 50s were the most interested. In other words, it can be seen that there is a lack of interest in regions other than Seoul and Gyeonggi and among those in their 10s, 20s, and 30s. The main behaviors of Seoullo 7017 are' night view' and 'walking', and the factors that affect culture and art are elements related to culture and art. If various programs and festivals are opened and actively promoted, the main behavior will be more varied. On the other hand, the main behavior that the users of Seoullo 7017 want is 'sit', which is a static behavior, but the physical conditions are not sufficient for the behavior to occur. Therefore, facilities that can cause sitting behavior, such as shades and benches must be improved to meet the needs of visitors. The peculiarity of the change in the behavior of Seoullo 7017 is that it is recognized as a good place to travel alone and a good place to walk alone as a public multi-use facility and group activities are restricted due to COVID-19. Accordingly, in a situation like the COVD-19 pandemic, more diverse behaviors can be derived in facilities where people can take a walk, etc., and the increase of various attractions and the satisfaction of users can be increased. Seoullo 7017, as Korea's first public pedestrian area, was created for urban regeneration and the efficient use of urban resources in areas beyond the meaning of public spaces and is a place with various values such as history, nature, welfare, culture, and tourism. However, as a result of the use behavior analysis, various behaviors did not occur in Seoullo 7017 as expected, and elements that hinder those major behaviors were derived. Based on these research results, it is necessary to understand the usage behavior of Seoullo 7017 and to establish a plan for spatial system and facility improvement, so that Seoullo 7017 can be an important place for urban residents and a driving force to revitalize the city.

Issues over morality and profit usually address relations between moral principles and material gains. In the history of traditional Oriental philosophy, discussions about them were called "Yi-Li zhi bian." The ideas of Confucius and Mencius also contain various discussions about Yi-Li. Both Confucius and Mencius defined Yi as a value concept to represent "natural," "appropriate" or "just" and regarded Yi as an external moral principle on the one hand and an internal moral emotion on the other hand. They had, at the same time, differences, as well. While Confucius placed importance on the external and acquired nature of Yi as a goal of morality, Mencius argued for the internal and innate nature of Yi as the nature of morality partially while recognizing its externality overall. Such Yi is a general term for subjective moral emotions and objective moral principles. Li was a concept of fact to represent "gain," "profit" or "profit-making." Both of them were against private interest and emphasized public interest. As for their differences, Confucius was positive about Li to some degree by saying "One should think of Yi when making profit," whereas Mencius was almost negative about Li and perceived it to be for Yi by saying "One should give up even his own life for Yi." He meant Li's dependence on Yi and also Yi's absoluteness for Ri. Both of them found a mix of opposite features in Yi such as internality and externality, subjectivity and objectivity, specificity and generality, and uniqueness and universality and also in Li such as individuality and specialty and public and private interest. Those features have both disadvantages including theoretical irrationality and logical contradiction and advantages including ideological diversity and conceptual polysemy. If efforts are made to avoid their disadvantages and highlight their advantages, they will provide some elements to consult in the creation of new global ethics required today when East and West are becoming one. In the modern society, the Yi-Li issues can be divided into the issues of morality and economy, personal and social profit, and moral ideal and material gain. If these modern Yi-Li issues are combined with the traditional Yi-Li issues, two paths will emerge over the order of Yi-Li. Of the many perceptions of Yi-Li issues of Confucius and Mencius, the idea of "Yi First, Li Later" can be very useful for creating a new ethics theory to represent "humanism" that we all need today when everyone considers their own pursuit of profit and satisfaction of needs as the best values. Sound Yi-Li relations will be possible only through Yi's orientation toward externality based on internality and Li's pursuit of private interest on the premise of public interest according to the spirit of "Yi First, Li Later."

The purpose of this study is to investigate the characteristics of Confucianism, Buddhism, and Taoism and to examine the characteristics of Intermixture of Three Religions in Journey to the West. This novel, which has the structure of satire, hope, and surrogate satisfaction while being the center of satire and humor, is a refuge for the people. Even today, it can be said, however, that for the people, Confucianism, Buddhism, and Taoism was not a distinctly separate system of religions. Journey to the West story is about the liberation of Buddhism that is obtained through Taoism training. In the celestial world, not all gods are perfect, and often make mistakes. In such a story, the mistakes of beings living as human beings are simply insignificant. What is not different from the structure of life in this world is still a world of nature. The world is rife with absurdities, both on earth and in heaven. The characteristics of Intermixture of Three Religions can be summarized in several ways. First, the Trip of Samjang is not just to gain the enlightenment of illegal but rather to seek a greater sense of meaning. Second, the means to gain enlightenment is that it does not claim that one is right or good. Third, mercy, goodwill, and respect for life for oppressed and exploited peoples are common to all religions. Fourth, this story suggests that everything from the beginning is already a matter of mind. Fifth, all of the logic of Three Religions in this novel can be said to be "preliminary." Human life implies that it is going on a planned path, perhaps as a fate. But the important thing is, as in all religions, even if the road is a planned one, Journey to the West is strongly and persuasively speaking that it is the way of life as well as the attitude of living silently in carrying out its duties.

The poems of Shin Suk-ju can be divided into two periods around the political change by King Sejo; his poems from the former period show that the poet enjoyed abundant pride and leisurely spirit in the self-satisfying world driven by his determination to maintain a pure heart and save and awaken the people during the reign of King Sejong. His ideology of awakening the people, however, was the product of his heroic consciousness to achieve immortal fame. It was his heroic consciousness and determination to sacrifice his life for fame according to the mandate from Heaven that made him join the political change by King Sejo. His poems from the latter period clearly reveal that the way of his life to pursue fame didn't bring him spiritual satisfaction and happiness. He confessed that his conscience was destroyed as he joined King Sejo in his political change and the deeds he achieved and further his life itself were all in vain. He lost the values or orders he pursued, which caused instability in his life. Facing such instability head-on, he argued that right and wrong, true and false, and good and evil mentioned in the world were all subjective and groundless. Furthermore, he realized all the things and creatures of the world were nothing but phantoms. Those perceptions he had were based on Madhyamaka of Buddhism. Going through such a thinking process, the poet wrote about his mentality of a false reputation with ideal mentality. Heroic consciousness, Buddhist thinking, and pursuit of mentality of a false reputation found in his poems make also frequent appearances in the poems by major literary men in the latter half of the 15th century such as Seo Geo-jeong. His serious searches to overcome his conscientious agony and sense of futility about life had influences on the attitudes toward life and literature of the official literary men of the times. Seong Hyeon's statement that the major literary figures of the times inherited the literary tradition of Shin Suk-ju was not a rhetoric by courtesy.

This study collected and analyzed transportation card data in order to better understand the operation and usage of city buses in Ulsan Metropolitan City in Korea. The analysis used quantitative and qualitative indicators according to the characteristics of the data, and also the categories were classified as general status, operational status, and satisfaction. The existing city bus survey method has limitations in terms of survey scale and in the survey process itself, which incurs various types of errors as well as requiring a lot of time and money to conduct. In particular, the bus means indicators calculated using transportation card data were analyzed to compensate for the shortcomings of the existing operational status survey methods that rely entirely on site surveys. The city bus index calculated by using the transportation card data involves quantitative operation status data related to the user, and this results in the advantage of being able to conduct a complete survey without any data loss in the data collection process. We took the transportation card data from the entire city bus network of Ulsan Metropolitan City on Wednesday April 3, 2019. The data included information about passenger numbers/types, bus types, bus stops, branches, bus operators, transfer information, and so on. From the data analysis, it was found that a total of 234,477 people used the city bus on the one day, of whom 88.6% were adults and 11.4% were students. In addition, the stop with the most passengers boarding and alighting was Industrial Tower (10,861 people), A total of 20,909 passengers got on and off during the peak evening period of 5 PM to 7 PM, and 13,903 passengers got on and off the No. 401 bus route. In addition, the top 26 routes in terms of the highest number of passengers occupied 50% of the total passengers, and the top five bus companies carried more than 70% of passengers, while 62.46% of the total routes carried less than 500 passengers per day. Overall, it can be said that this study has great significance in that it confirmed the possibility of replacing the existing survey method by analyzing city bus use by using transportation card data for Ulsan Metropolitan City. However, due to limitations in the collection of available data, analysis was performed only on one matched data, attempts to analyze time series data were not made, and the scope of analysis was limited because of not considering a methodology for efficiently analyzing large amounts of real-time data.

The purpose of this study is to analyze the effects of the old people's self-efficacy on the quality of life. In other words, the impact of old people's self-efficacy on self-respect, old people's self-efficacy on quality of life, and old people's self-respect on quality of life were analyzed in depth. In particular, it was intended to use the recently emphasized variables of self-respect to verify the mediated effects of self-respect in the relationship between self-efficacy and flesh quality, suggesting ways to lead a happy life by improving the psychological satisfaction and quality of life through the participation of the elderly in sports-for-all. To achieve this purpose, 297 people aged 60 or older who participated in the sports-for-all program conducted by the city and district offices in Seoul for five months from May 1 to September 30, 2018 or who used public sports facilities such as parks and playgrounds were analyzed as subjects for research. The findings are as follows. First, the "self-efficacy" of the elderly participating in the sports-for-all has been shown to affect "self-respect." Second, the "self-efficacy" of the elderly participating in the sports-for-all has been shown to affect the "quality of life." Third, it has been shown that the "self-respect" of the elderly participating in sports for all affects the quality of life. Fourth, the "self-esteem" of the elderly participating in sports for all occurred in the relationship between self-efficacy and quality of life. The implications of this study are that the self-efficacy of the elderly participating in sports for daily life has been identified by using the parameters of self-respect. Through this, it was provided as empirical basic data to establish welfare policies for senior citizens to improve the quality of life of senior citizens by identifying their self-efficacy, self-respect, and quality of life.
