Purpose: The characteristics of site plan of dentistry through examining the schools of dentistry and dental hospitals in Korea and comparison between them are necessary for the development of planning of the dental healthcare system. This study has been started to provide basic information for the planning of education and hospital architecture in dentistry. Methods: Literature review of space analysis and investigation on current status of dentistry in Korea have been conducted. The site plans of eleven schools of dentistry and dental hospitals have been analyzed with S3 axial analyzer in space syntax. Results: The result of this study can be summarized in four points. The first one is that the site plan of school of dentistry and dental hospital is influenced on the location of main campus in the city. The second one is that the types of relationship between dentistry and main campus are diverse from school and hospital in the main campus to independent dental campus in the city center. The third one is that the integration, connectivity and ERAM(3) of dental hospital are greater than school of dentistry and it means that dental hospital is located in easy access area compared with school of dentistry. The fourth one is that school of dentistry roles the connection space between main campus and dental hospital. Implications: It is necessary to analyze the site plan and arrangement of school of dentistry and dental hospital in the campus to develop the dental healthcare system in the city.

Purpose: The analysis of spatial composition is required for the creation of healing environment in healthcare facilities. This study has been accomplished to provide basic data for the planning and design of hospital architecture. Methods: Literature review of healing environment and investigation on characteristics of spatial composition in healthcare facilities have been conducted. The architectural plans of four Sou Fujimoto's healthcare projects have been analyzed with space syntax. Results: The result of this research can be summarized as followed. First of all, the healing environments are consisted with architectural composition in addition to physical and psychological factors for healing environment. The second one is that the characteristics of spatial composition in Sou Fujimoto's healthcare projects are different private/public/corridor relationships in program configuration, loop or one direction circulation, combined or independent corridor with program, and radical or linear connection in spatial connection methods. The third one is that the characteristics of spatial composition in selected cases through space syntax are high variation on integration, low variation on connectivity, and high distribution in main circulation on ERAM(3). Implications: In addition to the specific spatial composition in healthcare facilities of the architect's project, it is necessary to analyze the relationship with other factors and facilities to develop the planning of hospital architecture.

The analysis of outdoor and indoor spatial composition with natural elements is required for the creation of healing environment in healthcare facility to provide basic data for the planning of hospital architecture. Literature review of healing environment and investigation on characteristics of spatial composition in architectural works and healthcare facilities have been conducted. The spatial composition of outdoor space for refuge and prospect from indoor space of Seoul National University Hospital have been analyzed. The result of this research can be summarized as followed. First of all, the main natural elements for healing environment are consisted with refuge in outdoor space and prospect from indoor space. The second one is that natural elements in Seoul National University Hospital are located in central, posterior, and lateral area of main hospital and connectivity, integration, and ERAM(3) which the characteristics of outdoor spatial composition with space syntax are focused on the museum of medicine and landscape area in the center of hospital. The third one is that the outdoor refuge and prospect from indoor space in Seoul National University Hospital can be replaced with cultural heritage like the site of Kyungmogungji and Changgyeonggung palace in and next to the hospital. In addition to the outdoor and indoor spatial composition, it is necessary to analyze the relationship between elements to develop the healing environment of hospital architecture.

In September 2017, an outbreak with high mortality, which showed the typical signs of ND, occurred among a flock of more than 2000 Eurasian collared doves in Konarak, southeast of Iran. A confirmed pigeon paramyxovirus type 1 strain was isolated from the brain tissues of the dead doves. The isolate, which was called Pigeon/Iran/Konarak/Barin/2017, was classified as a highly velogenic NDV. Complete genome sequencing and phylogenetic analysis showed that the isolate belonged to subgenotype XXI.2, which has never been reported from Iran before. The isolate had the highest homology (96.15%) with early 2010s Italian isolates. Further studies will be required to understand the diversity better.

We have investigated the crystal structure and electrical properties of Pt/SBT/$ZrO_2$/Si (MFIS) and Pt/SBT/Si (MFS) structures for the gate oxide of ferroelectric memory. XRD spectra and SEM showed that the SBT film of SBT/$ZrO_2$/Si structure had larger grain than that of SBT/Si structure. $ZrO_2$ film between SBT film and Si substrate is confirmed as a good candidate for a diffusion barrier by the analysis of AES. The remanent polarization decreased and coercive voltage increased in Pt/SBT/$ZrO_2$/Pt/$SiO_2$/Si structure. This effect may increase memory window of MFIS structure directly related to the coercive voltage. From the capacitance-volt-age characteristics, the memory windows of Pt/SBT (210 nm)/$ZrO_2$ (28 nm)/Si structure were in the range of 1~l.5 V at the applied voltage of 4~6 V. The current densities of Pt/SBT/ZrO$_2$/Si with as -deposited Pt electrode and annealed at $800^{\circ}C$ in $O_2$ambient were $8\times10^{-8} A/\textrm{cm}^2$ and $4\times10^{-8}A/\textrm{cm}^2$ , respectively.
