Urban park are indispensable elements of contemporary cities. However, the structure and culture of contemporary cities is currently changing. There are prevalent discourses that Olmstedian parte are no longer relevant to our new societies and cultures. New kinds of parks have emerged with different forms and functions. In order to propose a new paradigm for parks in the 21st century, we need to look back to the origin of modem parks, which is to say, Olmstedian parte. This paper aims to trace the background of park movements in the 19th century America and to identify and describe Olmsted's idea of urban parks. In addition, the paper will clarify the limitations and reinterpret the meaning of Olmsted's idea of urban parks. One idea behind the development of urban parte was to mitigate urban problems such as public health, alcoholism violence and class conflicts in 19th century industrial cities. The aim of urban park was partially achieved at that time. However, those parse did not serve the use of diverse classes. Olmstedian parks were designed for passive and civilized recreation, and lower classes were more attracted by active theme parks and areas such as Coney Island and John Wood. The strengths of Olmsted's idea of urban parte can be outlined as follows: First, designing parte goes beyond shaping physical lands to embrace social reforms. This means that park designers should have a critical understanding of society and culture. Also, landscape designers should have a bold vision for the future. Without such a vision and social agenda, landscape architects cannot postulate alternative possibilities through engaging in new practices. Second, Olmsted successfully adapted British landscape aesthetic ideas such as the picturesque, the sublime and the beautiful into an American context. Finally, his vision and idea of urban parks show us that landscape architecture is not just technical work, but that it can create a locus to engage a new cultural praxis by inventing cultural products - parks.

Purpose: There is little information about China's medical service system and health care facilities in Korean medical architecture papers, which is inconvenient for scholars engaged in medical building research and comparison. Futhermore, the transformation of the notion of health and the ascension of the service needs show the lack of medical function, and then make functions of hospital construction are always in the state of dynamic renewal. Therefore, the purpose of this study is to analyze the Chinese medical service system and general hospital related laws and regulations for future research to provide effective analysis of data, and find shortcomings. Methods: This study was conducted by a research on law and regulation of China's medical service system and general Hospital. Results: At present hospital construction in China is in the period of rapid development and it exposes the layout of medical health facilities is not reasonable and the service does not reach the designated position and so on. Overall, it requires more detailed guidelines to enhance the quality of medical health services. Implications: It is expected that the research of this paper will provide effective reference for future research on Chinese medical architecture system and medical facilities, and can promote and perfect the construction of Chinese medical architecture theory system.

Based on the literature statistical method, the paper publication status of the isolated working face and the distribution of the rockburst coal mine were obtained. The numerical simulation method is used to study the stress distribution law of working face under different mining range. In addition, based on the similar material simulation test, the overlying strata failure modes and the deformation characteristics of coal pillars during the mining process of the isolated working face with thick-hard key strata are analyzed. The research shows that, under the influence of the key strata, the overlying strata formation above the isolated working face is a long arm T-type spatial structure. With the mining of the isolated working face, a series of damages occur in the coal pillars, causing the key strata to break and inducing the rockburst occurs. Combined with the mechanism of rockburst induced by the dynamic and static combined load, the source of dynamic and static load on the isolated working face is analyzed, and the rockburst monitoring methods and the prevention and control measures are proposed. Through the above research, the occurrence probability of rockburst can be effectively reduced, which is of great significance for the safe mining of deep coal mines.

The path following problem of a ship sailing in restricted waters under wind effect is investigated based on Robust $H_{\infty}$ Guaranteed Cost Control (RHGCC). To design the controller, the ship maneuvering motion is modeled as a linear uncertain system with norm-bounded time-varying parametric uncertainty. To counteract the bank and wind effects, the integral of path error is augmented to the original system. Based on the extended linear uncertain system, sufficient conditions for existence of the RHGCC are given. To obtain an optimal robust $H_{\infty}$ guaranteed cost control law, a convex optimization problem with Linear Matrix Inequality (LMI) constraints is formulated, which minimizes the guaranteed cost of the close-loop system and mitigates the effect of external disturbance on the performance output. Numerical simulations have confirmed the effectiveness and robustness of the proposed control strategy for the path following goal of a ship sailing in restricted waters under wind effect.

Purpose: This study is a case study of a small-mid sized hospital to promote a full-scale remodeling to ensure the quality and competitiveness of the medical services and trying to arrange the remodeling characteristics of small-mid sized hospital which is suffering from aging facilities as well as chronic congestion and lack of spaces. Methods: Research was conducted by consultation with hospital executives and each department operators, and on-site investigation, Results: The result of this study can be summarized into two points. The first one is that existing statistical value like area per bed, in the remodeling of the small-mid hospitals may not mean much. planners have to verify the necessary room space areas in close consultation with the department operators. And after confirming layout possibilities, they have to create the program. The second one is that remodeling planning can be a realistic plan with structural and installation diagnosis at the same time. If so, it is advisable to proceed architectural design from the beginning for cost and time savings. Implications: This results can be applied to small-mid hospitals to apply to the medical law revision and others.

The resistance characteristics of a trimaran are studied, varying the bottom profile and transom stern of the main hull. The bottom profile is varied in three cases (convex, flat, concave). Using the experimental and numerical methods, the resistance performance of each hull form is compared. The experiments are carried out in ship model basin, and the numerical simulations are performed by a finite-difference method, based on the Marker and Cell scheme. Euler and continuity equationsare used for the governing equations of the flaw field around a trimaran with transom stern. The agreement of both results is good. The optimal bottom profiles for transom stern are presented for law-speed and high-speed regions, respectively.

In NATM tunnels, water inrush and tunnel collapse are often encountered in silty-fine sand with abundant water during excavation. Because of the special engineering properties of this stratum, grouting effect is difficult to achieve as expected, and it is a major problem in the field of civil engineering. Taking Beijing Metro Line 10 as a case, we applied PFC3D to simulate the process of grouting in this stratum. By analyzing the law of grout diffusing and porosity change under different grouting pressures, the study found that grouting was a process of splitting, and grouting pressure played an important role. The numerical results were verified by theoretical calculation analysis, and the grouting parameters were determined under the various grouting pressures for practice. After the excavation of this tunnel, the concretions in silty-fine sand are similar to the results of PFC3D simulation, which indicates that the grouting mechanism is confirmed by field observation further.
