This study analyzed the inflow factors of Yangjae Citizen's Forest Park using social big data generated online. To this end, the applicability of the emotional information analysis method is to be confirmed as a method of analyzing the perception of the city park and confirming the difference in the characteristics and use of the park. The analysis is based on big data, and as the core of the study is keyword network analysis, the methodology of the 'emotional information analysis method' patented by the author was applied. As a result of the analysis, among the influx factors of Yangjae Citizens' Forest recognized by citizens, the most positive emotional factor was derived as a factor related to 'park contents', and the negative emotional factor was derived as a factor related to 'park management'. These research results suggest that more in-depth program development and operation are needed to discover 'park contents' when implementing urban park revitalization support projects in the future

This research aimed at understanding recognition of the park's community garden, public evaluation of it, and user awareness of the public enhancement plan. This was based on the problem that arose in the park community garden as public awareness research along with community garden cultivation participation within the urban park. In order to compare recognition differences along with community garden cultivation participation, the researcher conducted an analysis by dividing research participants into a cultivation participant group and non-participant group. As a result first, the cultivation participant group positively recognized the necessity of the community garden compared to the non-participant group. However, they recognized the community garden as a space for private profit, which threatened the public aspect of the park. Second, as a result of evaluating community garden publicness, the non-participant group which was alienated from community garden use, had a negative opinion about the community garden. Third, as a result of researching awareness of the community garden distribution method and consumption to promote publicness of the community garden, the cultivation participant group recognized the community garden as a space for private profit. Therefore, it is necessary for both groups to be aware of the public value of the community garden among the park users for sustainable management and operation. The significance of this research is the direction in the aspect of users to form, manage and operate the community garden in the urban park without damaging publicness of the park or conflicting between the function of the park and the function of the community garden. Henceforth, the researcher expects that this research can be utilized to maintain publicness of the park in respect of formation of the community garden in the park and management and operation.

Urban park planning has become difficult due to the lack of municipal funds. Thereupon, a special scheme was imposed for city park planning. Since then, a legal amendment was made for economical improvement and more active participation. However, there are a lot of questions about whether it was a suitable direction for parks and where it should be emphasized for public interest. Base on these concerns, this study examined the basis and characteristics of location, creation, and maintenance of private development parks in Japan, which was the policy model of Korean private parks. Location and space planning of private development parks was made up considering an effective green network and disaster prevention function, and a minimum area was about 1.42ha. The minimum area, 1ha, was established on the basis of considering realistic possibilities, disaster protection, and universal validity. It was also amended to consider the standard of type two mid- to high-rise exclusive residential areas and consultation with regional governance. Finally, it was built on the lowest limit of ordinance of the relevant city; for example, 100% of the floor area ratio, 30% of the building coverage ratio, and the maximum height of 11 stories, etc. For maintenance, private and public sectors were working together. Maintenance fees for 35 years (based on $300yen/m^2$ per month) were paid en bloc by the licensee. However, the city was paid for facilities that accompanied excessive maintenance costs. Meanwhile, it seemed difficult to introduce attractive profit facilities because of the limitations in location, usage permission, and introduction equipment; furthermore, there were problems with management authority, and the burden of expenses was deducted. For creating private Korean parks, this study suggested that we should build priority of creating city parks and select appropriate locations first; also, we need to make criteria for location, creation, and standard management rules that are relevant to the whole nation of Korea.

This study aims to create a basic model for classifying the activity photos that urban park users shared on social media using Deep Learning through Artificial Intelligence. Regarding the social media data, photos related to urban parks were collected through a Naver search, were collected, and used for the classification model. Based on the indicators of Naturalness, Potential Attraction, and Activity, which can be used to evaluate the characteristics of urban parks, 21 classification categories were created. Urban park photos shared on Naver were collected by category, and annotated datasets were created. A custom CNN model and a transfer learning model utilizing a CNN pre-trained on the collected photo datasets were designed and subsequently analyzed. As a result of the study, the Xception transfer learning model, which demonstrated the best performance, was selected as the urban park user activity image classification model and evaluated through several evaluation indicators. This study is meaningful in that it has built AI as an index that can evaluate the characteristics of urban parks by using user-shared photos on social media. The classification model using Deep Learning mitigates the limitations of manual classification, and it can efficiently classify large amounts of urban park photos. So, it can be said to be a useful method that can be used for the monitoring and management of city parks in the future.

Light has been an essential part of human life. The advancement of technology has changed cities' nightscape and night activities in a drastic way. Lighting has influenced the identity of a city while promoting a variety of civic nighttime cultural pursuits, yet lighting design has not been considered adequately in the field of landscape architecture. This study aims to analyze the current status of lighting in urban parks through interviews with professionals, literature and regulation reviews, analysis of design documents and a field survey focused on Yeouido Park in Seoul. The findings and improvement directions are as follows. First, it is necessary to develop a specific lighting design method in order to avoid a marginalized, passive approach such as light fixture installation. Second, the existing standards of illuminance by KS A 3011 regulating only horizontal illuminance has turned out not to evaluate the current nightscape of urban parks properly. Therefore the criteria and guideline for analysis and design for nightscape should be articulated. Third, there are no design or management strategies to consider the changing landscape of urban parks, which is necessary due to the changing characteristics of park ecosystems. Lastly, detailed guidelines for distinguished spaces in urban parks should be studied and suggested.

한국형 표준 원자력발전소의 정지냉각운전시 최대냉각율은 75$^{\circ}$F/hr(41.7$^{\circ}C$/hr)로 기술사양서에 규정되어 있다. 정지냉각운전 냉각율에 가장 큰 영향을 미치는 2가지 중요한 변수는 정지냉각계통 열교환기를 지나는 원자로냉각재 유량과 기기냉각수의 온도다. 이중 열교환기를 지나는 원자로냉각재 유량은 butterfly형 정지냉각계통 유량조절밸브의 개도에 의하여 조절되는데 개도에 따른 throttle 능력이 중요한 인자다. 또 기기냉각수의 온도는 해수온도의 변화에 따라 편차가 발생하므로 유량조절밸브의 개도와 기기냉각수 온도의 상관관계에 따라 냉각능력이 달라진다. 본 논문에서는 현 울진 3&4호기 정지냉각계통 열 교환기 및 조절밸브 둥의 설비를 기준으로 기술사양서 상의 냉각율 75$^{\circ}$F/hr(41.7$^{\circ}C$/hr) 유지가 가능한 최저 기기냉각수의 온도를 찾아보았고, 아울러 기기냉각수의 온도와 조절밸브의 개도 사이의 관계를 조사하였다. 그 결과 현재의 울진 3&4호기 조절밸브를 최저개도로 조절할 때 약 57$^{\circ}$F(13.9$^{\circ}C$)의 기기냉각수가 공급되어도 냉각율 제한치를 넘지 않는 것으로 분석되었다. 한편, 최저조절가능 유량이 약 2000 gpm(7570 l/min)일 경우에는 낮은 기기냉각수가 공급될 경우 최대냉각율을 초과하므로 한 train을 정지시키고 한 train만으로 운전할 것을 고려하여야 할 것으로 보인다. 이 경우 최저 약 56.5$^{\circ}$F(13.6$^{\circ}C$)의 기기냉각수가 공급되어야 한다. 본 논문의 분석결과는 향후 기기설계사양서나 운전지침서 등에 반영되어 실제 발전소 설계 및 운전절차 수립에 기여할 수 있을 것으로 생각된다.공감대의 형성이 요구된다. 질적 측면에서는 공원 녹지의 기능성의 회복이라는 측면과 시대에 부합되는 새로운 기능 및 가치의 부여가 필요하며, 이를 위해서는 공원의 매력, 공원의 시설기능 증진, 녹지의 질의 향상 및 녹지 가치의 증진에 대한 다양한 시책이 요구된다. 구성적 측면에서는 공원녹지의 개별적 존재보다는 공원 녹지를 상호간 유기적인 계통을 확보하여 공원 녹지의 네트워크를 형성하여 도시 속의 산재된 고립된 섬으로서의 공원 녹지가 아닌 시민생활에 늘 가까이 있는 생활 속의 공원녹지로 재편되어야 한다. 이러한 정책의 의제는 양적 측면에서 보전(CONSERVATION)과 창출(CREATION), 질적 측면에서 쇄신(RENOVATION)과 복구(RESTORATION), 그리고 구성적 측면에서 공원 녹지의 연결(CONNECTION)과 시민 참여에 의한 운동(MOVEMENT)이라는 정책 개념의 구현을 통해 가능하다. 이러한 정책 개념과 의제를 가지고 서울시 공원 녹지 정책을 구체화시키기 위해서 푸르름의 새로운 탄생이라는 기치 아래 풍요로운 서울, 사랑 받는 공원, 생활 속의 녹지의 3대 목표, 공원 녹지의 보전, 잠재 공원 녹지의 창출, 공원의 활성화, 녹지의 복구, 경관 보전 및 복구, 공원 녹지의 네트워크, 도시 녹화의 7대 과제를 설정하고 미시설 공원 녹지 집행, 개발 사업시 공원 녹지의 확보, 환경 녹지의 총량 보호 관리, 도시 소공원 개발, 역사 문화 공원 조성, 하천 공간 복원, 공원 시설 기능 개선, 이용 프로그램 개발, 공원 관리 개선, 환경 피해 녹지의 회복, 도시 환경 림 조성, 녹지 기능 증진, 도시 자연 경관 보전, 공원 녹지체계 구성, 공원 녹지 공급 균형, 주변 환경 녹화, 가로 녹화의 17개 시책을 제안하였다. 이러한 정책사업의 원활한 추진을 위해서는 기존의 관주도의 일방적인 공원 녹지 행정이 아닌 시민의 참여를 통한 시민이 함께 하는 정 책 사업의 추진이 요구되며, 특히 민간 부문의
