Traumatic spinal cord injury (SCI) research has recently focused on the use of rat and mouse models for in vivo SCI experiments. Such small rodent SCI models are invaluable for the field, and much has been discovered about the biologic and physiologic aspects of SCI from these models. It has been difficult, however, to reproduce the efficacy of treatments found to produce neurologic benefits in rodent SCI models when these treatments are tested in human clinical trials. A large animal model may have advantages for translational research where anatomical, physiological, or genetic similarities to humans may be more relevant for pre-clinically evaluating novel therapies. Here, we review the work carried out at the University of British Columbia (UBC) on a large animal model of SCI that utilizes Yucatan miniature pigs. The UBC porcine model of SCI may be a useful intermediary in the pre-clinical testing of novel pharmacological treatments, cell-based therapies, and the "bedside back to bench" translation of human clinical observations, which require preclinical testing in an applicable animal model.

The purposes of this research were to identify nursing interventions performed by Korean nurses and to compare the interventions performed by nurses working in the oriental medicine hospitals and with those performed by nurses working in the general hospitals. The samples consisted of 144 Korean nurses working in three hospitals, 70 nurses working in the oriental medicine hospitals and 74 nurses working in the general hospitals. The Nursing Interventions Classification (NIC) Use Questionnaire developed by the Iowa Intervention Project team was translated to Korean and verified using the method of back-translation. The questionnaire consists of 433 intervention labels and definition. Thirteen interventions were used at least daily by nurses working in the oriental medicine hospitals, while twenty-one interventions were used at least daily by nurses working in the general hospitals. The most frequently used interventions by nurses working in the oriental medicine hospitals were Documentation, Shift Report Vital Signs Monitoring, Pressure Ulcer Prevention, Positioning, Fall Prevention, Exercise Promotion, Intravenous (IV) Therapy, Pressure Ulcer care, and Bed Rest Care in that crder. For nurses working in the general hospitals the most frequent intervention was Analgesic Administration, followed by the interventions of Medication Administration : Parenteral and Intravenous Therapy (IV) Therapy, Documentation, Intravenous(IV) Insertion, Shift Report, Fall Prevention, Vital Signs Monitoring, Medication Adnninistraction : and, Fluid Monitoring, and Medication Maragement in that order. The interventions performed least often by nurses working in the oriental medicine hospitals were Hemodialysis Therapy and Bleeding Reduction : Antepartum Uterus, while the interventions performed least often by nurses working in the general hospitals were Rape Trauma Treatment and Contact Lens Care. The nurses working in the oriental medicine hospitals performed the interventions in the Physiological : Complex domain significantly more often than the nurses working in the general hospitals, while the nurses working in the general hospitals performed the intervention in the Behavior domain significantly more often than the nurses working in the oriental medicine hospitals. This study suggests that further study will be needed to developed and validate more interventions sensitive to Korean culture.

Spinal instability known to be related to low back pain. However, the quantitative definition of spinal instability has not been established because there is a lack of consensus regarding clinical and radiological studies. In addition, the major factors affecting such instability have not been elucidated, although disc degeneration, disc injury, ligament injury, and isthmic defects are considered to result in such problems. In this study, individual and combined influences on spinal instability with a three-dimensional finite element model of a one-level lumbar spinal motion segment were investigated, under the assumption that the rotation and translation in the sagittal plane under flexion and extension represented the instability indices. The results could be helpful in understanding the causes and mechanisms of spinal instability in the lumbar spine.

Recently, due to the development of mobile phone and supply of smart phone, many contents have been developed. Especially, since the small-sized cameras are equiped in mobile devices, people are interested in the image based contents development, and it also becomes important part in their practical use. Among them, the character recognition system can be widely used in the applications such as blind people guidance systems, automatic robot navigation systems, automatic video retrieval and indexing systems, automatic text translation systems. Therefore, this paper proposes a system that is able to extract text area from the natural images captured by smart phone camera. The individual characters are recognized and result is output in voice. Text areas are extracted using Adaboost algorithm and individual characters are recognized using error back propagated neural network.

Since the omnidirectional camera system with a very large field of view could take many information about environment scene from few images, various researches for calibration and 3D reconstruction using omnidirectional image have been presented actively. Most of line segments of man-made objects we projected to the contours by using the omnidirectional camera model. Therefore, the corresponding contours among images sequences would be useful for computing the camera transformations including rotation and translation. This paper presents a novel two step minimization method to estimate the extrinsic parameters of the camera from the corresponding contours. In the first step, coarse camera parameters are estimated by minimizing an angular error function between epipolar planes and back-projected vectors from each corresponding point. Then we can compute the final parameters minimizing a distance error of the projected contours and the actual contours. Simulation results on the synthetic and real images demonstrated that our algorithm can achieve precise contour matching and camera motion estimation.

Objectives The purpose of this study is to provide Korean version of mild traumatic brain injury assessment tool. Methods The original version of acute concussion evaluation (ACE) was translated into Korean, and it was then back-translated into English without any prior knowledge of ACE. Finally, the pre-final version of Korean version of acute concussion evaluation (K-ACE) was derived. 49 Korean patients who had been diagnosed with mild traumatic brain injury participated in the study and completed K-ACE. Overall, 44 data were used to analyze findings. Validity of the study was assessed based on Concurrent validity. Reliability was also evaluated using Cronbach's ${\alpha}$ and the intraclass correlation coefficient. Results The Cronbach's ${\alpha}$ value for each item presented a proper level of internal consistency with results of 0.711 to 0.893 in two evaluations, respectively. The intraclass correlation coefficient of the retest reliability was marked as 0.892 (95% CI 0.840~0.933). Concurrent validity demonstrated positive correlations between K-ACE and Korean version of postconcussional syndrome questionnaire. Conclusions The K-ACE is concluded as a valid and reliable tool for measuring mild traumatic brain injury and post-concussion symptoms. Upon completion of the follow-up study, the K-ACE will be well-utilized by both clinicians and researchers.

In February 2019, a damping-off disease occurred at the seedling stage of paprika in a commercial nursery located in Cheorwon, Korea. A species of Fusarium was isolated from the diseased plant and it was identified as Fusarium oxysporum based on morphological characteristics and nucleotide sequence data of translation elongation factor $1-{\alpha}$ and the largest subunit of RNA polymerase. The isolate obtained was revealed to be pathogenic to the host plant through pathogenicity tests, and the reisolation of the pathogen confirmed Koch's postulates. This is the first report of damping-off caused by Fusarium oxysporum on paprika in Korea.

The purpose of this study is to get a more fundamental definition of the term Architecture and Geonchuk through analyzing the origin and reception of the terminus technicus Architektonike. In Latin world the greek term Architektonike was adopted and replaced the term Constructio by Vitruvius and has played a significant role in the history of architecture. In the late 19th Century however, the word Architecture was translated into Geonchuk(建築) and has been dominantly used in countries such as Korea, Japan, and China. But the difference of the denotation between them has not yet been fully evaluated. The term Geonchuk signifies much the same as the Tektonik and remains as such in the architectural discourse. In this context, this study goes back to refer to the philosophy of Metaphysics by Aristotle. In his book the term Architektonike was defined for the first time as terminus technicus, and the philosophies in later Ages of Leibniz or of Kant adopted it to signify the world view in accordance with the time. However, the original thought of the Architektonike disappeared in architectural practice and has been used in most cases as a substitute for Oikodomike which denotes house-building. The usage of this word in later time shows that it lost its foundation to be interpreted not only in terms of principium cognoscendi, but also in terms of principium reale. From this the literal usage of the term architecture and Geonchuk has seldom to do with its original meaning and denotation of Architektonike and also they lost the status of terminus technicus for the discourse of arche which encompasses the meaning of both principle and universal order.
