The three generations of Haenam Yoon, who have been handed down to Gongjae Yoon DuSeo (1668~1715), Yoon DeokHee (1685~1776) and Yoon Yong (1708~1740), were based in Haenam. They had an artistic soul on the stage of Hanyang and succeeded in the art of the family, building a reputation as a family of Seonbi painters representing the late Joseon Dynasty. Born as the eldest son of Gongjae and lived at the age of 82, Rakseo learned a variety of studies, calligraphy and painting from his father and Lee Seo. While learning the paintings of the early and mid Joseon period, and accepting the Namjong painting method, he pursued the realism and three-dimensional sense of the subject by adding a Western-style shading method. In particular, he showed outstanding talent in horse paintings and pottery figures, expressing his original 'Beauty that realistically portrays real scenery'. Cheonggo, who was born as the second son of Rakseo and died at the age of 32, was good at Namjong landscape painting using various tree drawing methods. He painted the original Siuido by changing the topical poems, as well as detailed observations and explorations to accurately describe the facts of the object. In addition, 'Beauty showing affection through realistic scenery' was expressed by newly changing and reinterpreting the tendency of home appliances painting to express the spirit as a form beyond the realistic landscape. Rakseo and Cheonggo father and son made a 'NogUdang' painting style, drastically changing the paintings of the late Joseon Dynasty, and had a great influence on the history of Korean painting.

In the era of low growth, many provincial cities are experiencing population decline and aging. Population decline phenomena such as reduction of productive manpower, reduction of finances, deterioration of quality of life, and collapse of the community base are occurring in a chain and are being pushed to the brink of extinction of the cities. This study aims to propose a methodology to objectively estimate the employment creation centers and setting the basic unit of industrial-centered zoning by applying spatial statistical techniques and GIS for the application of the compact city plan as an efficient spatial management policy in a city with a declining population. In details, based on reviewing previous studies on compact city, 'employment complex index(ECI)' were defined considering the number of workers, the number of settlers, and the area of development land, the employment creation center was estimated by applying the 'Local Moran's I' and 'Getis-Ord's Hot-Spot Analysis'. As a case study, changes in the four years of 2013, 2015, 2017, and 2019 were compared and analyzed for Changwon City. As a result, it was confirmed that the employment creation center is becoming compacted and polycentric, which is a significant result that reflects the actual situation well. This results provide the basic data for functional and institutional territorial governance for the regional revitalization platform, and provide meaningful information necessary for spatial policy decision-making, such as population reduction, regional gross domestic product, and public facility arrangement that can respond to energy savings, transportation plans, and medical and health plans.

Ports have had a positive impact on urban development in the past, but they also have external diseconomies that reduce the competitiveness of port cities, such as damage to the residential environment. As a result, ports are also important policy targets for local governments. However, opportunities for participation by local governments are limited due to the centralized port policy structure and the lack of port capacity of local governments. Therefore, there is a growing interest in local port governance, which approaches the port as a target of local policy and seeks to solve it based on the participation and cooperation of various members such as local governments, general citizens, local businesses, and NGOs. The purpose of this study was to find the components for establishing local port governance and explore priorities by conducting AHP targeting experts and practitioners. As a result, in order to establish local port governance, it was confirmed that the establishment of an institutional foundation and a socio-cultural atmosphere is the top priority. More specifically, the interest and will of local governors, and local autonomy laws that are the institutional foundation to support the actual operation and the securing of the expertise of local government officials found to be of high priority.

Many industries are being severely damaged by COVID-19, a respiratory infection that has recently been prevalent around the world. In particular, for workers in the construction industry, it is impossible to work from home, and if an outbreak on a construction site is confirmed, it can lead to great damage. Accordingly, the government has drafted 「Guidelines for Response to Construction Sites for Prevention and Spread of COVID-19」. In addition, domestic and foreign research about COVID-19 in the field of construction sites is being actively conducted. However, Korea has lacked studies on the effectiveness of the countermeasures in place at construction sites, or that reflect the opinions of construction site workers. Therefore, this study conducted a survey of construction site workers by dividing the construction of the COVID-19 quarantine management system and response plan into on-site management and social management. Through the AHP/IPA analysis, it was found that among social management, 'infectious disease management system and cooperation system with related institutions' and 'reduction of working hours' are areas with high importance but low satisfaction. After that, the causes of the two items were analyzed and related countermeasures were suggested. The results of this study will be able to contribute to the improvement of the quarantine management system and response plan at construction sites, and to minimize the damage to the construction industry related to COVID-19.

COVID-19 has caused the dramatic reduction of public transportation demand in Busan Metropolitan City, that is, daily public transportation trips in 2020 dropped by approximately 920,000 trips from 2019 based on the public transportation card data. This study investigated the underlying factors affecting the public transportation demand discrepancy between before and after COVID-19 at the primary administration unit(i.e., Eup, Myeon, Dong) level with Ordered Logistic Regression model. Finding of this study is as follows. The primary administration units characterized with high ratio of welfare recipients, industrial area, and day boarders were heavily dependent on public transit, indicating little change in public transportation demand. On the other hands, the primary administration units which have high ratio of urban rail transit uses experienced significant reduction of public transportation demand. In conclusion, transportation policies taken under emergent situation such as COVID-19 need to take into account the region-based characteristics rather than unilateral ones.

Bus stop is necessary to improve user-focused environment to offer convenient service because of the large number of passengers. This study is to analyze user's evaluation and establishment model of the service levels at bus stop using GAP analysis, IPA and Structural equation model and suggests improvement direction of bus stop. In the GAP analysis, on thirty-one service items of bus stop, the difference appeared highly from the items such as obstacle's facility and the information related to the using bus. In the current IPA service bus operation information, cadence facility and obstacle support facility need to be improved. And in service expectation bus operation information and th exchange facility, the obstacle support facility need to be improved continuously. The evaluation model of bus stop service due to a structure equation's was fitted well by structure equation. In overall satisfaction on bus stop, the waiting satisfaction is more affect the satisfaction of bus use facility. Satisfaction in bus use facility, the related information of bus operation, cadence facility, bus operation information and trans facility, obstacle support facility is more affect compare to other items. The lower overall satisfaction in bus stop is the higher the expectation of overall satisfaction is. Therefore, the information of bus operation and the support facility for the handicapped needs an active improvement plan than ever.

Mass transit information can contribute many benefits to users. Especially, transportation information technology is developing highly with information technology in Korea recently. Hereafter, it is expected to give customized transportation information to users individually with the advent of ubiquitous age in earnest. This public transportation information service can be realized by path finding algorithm in public transportation networks including travel and transfer attributes. In this research, constraints are constructed with the primary facts influencing users. Moreover, the method reducing user's path finding condition arbitrarily is proposed by making the maximum value as variables. In this study, transfer frequency, total travel time, seat confirmation, transfer time and travel time become constraint condition based on k path finding algorithm considering service time constraint condition. Moreover, case study about user customized transfer information is performed in Seoul and metropolitan subway networks.

Because of the insufficiency of ground space, the utilization of underground is getting more and more in these days. Moreover, underground space is being used not only buildings but multipurpose space for movement, storage and shopping. However, ground space has vital weakness for fire compared to ground space. Especially in case of underground shopping center, there are various stuffs to burn and poisonous gas can be exposed on this count when the space is burned. A large number of casualties can be also occurred from conflagration as underground space has closed structures that prevent rapid evacuation and access. Therefore, this research proposes the guidance methodology for evacuation from conflagration in large-sized underground facilities. In addition, suggested methodology uses high technology wireless sensor information from up-to-date ubiquitous sensor networks. Fire information collected by sensors is integrated with existing underground facilities information and this is sent to guidance systems by inducing process. In the end, this information is used for minimum time paths finding algorithm considering the passageway capacity and distance. Also, usefulness and inadequacies of proposed methodology is verified by a case study.

This study aims to conceptualize 'perceived disability discrimination', to evaluate the coverage of Korea's Disability Discrimination Act from the perspective of perceived discrimination, and to discuss the possibility of legal judgement on the perceived disability discrimination. As a general concept, it is the perceived discrimination that people with disabilities feel or experience any type of discrimination based on stigma, disability oppression, prejudice, or stereotype. The Korea's Disability Discrimination Act does not consider some perceived discrimination as a subject of legal judgement. Although indirect discrimination is a very good content to correct wrong social rules, values, institutions, actually, it is confronted with being remained useless. Perceived disability discrimination such as strangers' staring or benevolent disability discrimination are not included in the coverage of Korea's Disability Discrimination Act. The disability discrimination experienced by family members who has a disabled member was not a matter of current Korea's Disability Discrimination Act. Considering perceived disability discrimination, coverage of Korea's Disability Discrimination Act should be extended to the concept of discrimination against disability, not against people with disability. Based on the concept of indirect discrimination, social rules and institutions should be examined if they are discriminative or not in dealing with the matters of people with disabilities. Also, for judging perceived disability discrimination, it is necessary to use 'the standard of reasonable people with disability', which comes from judgement standard of sexual harassments. The reality of oppressive ideology against disability should be socially accepted and the social reconstruction for people with disabilities should go on.

Seat reservations and civil complaints in the library reading room have been done face-to-face by managers, and efficient management has been difficult. In addition, there is a problem that it is difficult to take action in the event of a civil complaint due to user inconvenience, such as a noise problem between users in the reading room. In this study, an online reservation system was developed for efficient management of seats in the library reading room so that it could be serviced non-face-to-face. In addition, when using the library reading room, it is possible to apply for non-face-to-face civil complaints when complaints occur due to noise problems between users, loss of belongings, and snoring during the user's sleep. Managers can smoothly manage library reading rooms through non-face-to-face inconvenience reports. It is possible to increase the satisfaction of using the library by resolving the inconvenience of users. The developed service app allows seat reservations and anonymous inconvenience reports. The administrator can check the received inconvenience report and warn the user of the seat with an IoT sensor-based LED. When corrective action is completed, the result of the action may be fed back to the reporter.
