The purpose of this study is to investigate Seonyudo Park and Kkummaru in terms of haptic space. This is also an attempt to explore temporality of appearing in architectural spaces with reference to cinematic expression in which time is visible and perceptible. The film of Chris Marker's La Jet$\acute{e}$e depicts temporal relationship by indeterminate continuum, reading the space on the disjunctive relationships of visual and auditory, and aberrance of time and space. Based on the three categories that is derived from those discussions, this study analyzes the experience of non-chronological time induced by architectural devices: the bifurcation of indeterminate circulation, the readability of space on the disjunction of visual and auditory, and the border-dismantling. Therefore, this study have a relationship with the contemporary discourse on time and events as transformation and becoming, and it means to escape from the deterministic thinking to emphasize invariability and space rather than variation and time.

This study, through biomechanical analysis, conducts a risk assessment of injury occurrence in ballet dancers while they perform running and jumping movements. The participants were nine female collegiate students majoring in ballet(age: $20.89{\pm}1.17years$; height: $160.89{\pm}7.01cm$; mass: $48.89{\pm}3.26$). Descriptive data were expressed as $mean{\pm}standard$ deviation(SD) for all variables. An independent t-test was conducted to determine how the following variables differed: duration time, position of the center of gravity, angle of the hip, torque of the hip, and muscle activity. All comparisons were made at the p<0.05 significance level. The results show that the jump time was two times longer than the run time in the duration time. The jump length was also longer than the run. The angle of the hip and the torque at the hip were higher in the right. The vastus medialis muscle was most frequently used. These findings demonstrate that participants' jumps may require more biomechanical variables for performance of better and more correct $jet{\acute{e}}$.

The purpose of this study was to investigate time of the phase, angle of the right ankle, knee, and hip joint, lateral angle of the trunk, mediolateral displacement of COM, and vertical displacement of COM between two groups while executing grand battement $jet{\acute{e}}$ $\acute{a}$ la seconde in a center exercise setting through 3D video analysis. The subjects participated in this study were skilled and unskilled 6 female ballet majors in Busan, respectively. The conclusions are as follows: 1. The time of the phase 2 was faster than P3. It shows a significant difference(p<.05) for P1 and P4 between skilled and unskilled groups 2. The angle of He right ankle joint has a significant difference(p<.05) at E4 between skilled and unskilled groups. The angle of the right knee joint has no significant difference at all events between skilled and unskilled groups. The angle of the right hip joint has a significant difference(p<.001) at E3 between skilled and unskilled groups. 3. The lateral angle of the trunk has a significant difference(p<.05) at E1 and at E5 between skilled and unskilled groups. The skilled group of the lateral angle of the trunk was lower than the unskilled group. However the skilled group's lateral angle of the trunk was bigger than the unskilled group at E3. It has significant difference(p<.001) at E3 between skilled and unskilled groups. 4. The mediolateral displacement of COM has no significant difference at all events between skilled and unskilled groups. The vertical displacement of COM has a significant difference(p<.01) at E3 between skilled and unskilled groups.

A one-year-old, 3.25 kg intact male Chinchilla cat presented with acute right hind limb paralysis. Diagnostic imaging studies found cardiomegaly with interstitial lung pattern, abnormal mitral valve leaflets without maximum opening at the end of the ventricular diastole and during atrial systole and severe mitral inflow obstruction. Based on these findings and its young age, the case was diagnosed as congenital mitral valve stenosis. Treatment was directed to stabilize clinical conditions related to heart failure, to prevent further formation of thrombus and to relieve pain associated with thromboembolism. After one month of therapy, hind limb motor function was fully recovered.
