A case of visual loss following cranio-maxillofacial trauma is reported. The patient had acute optic nerve injury associated with a fracture of the right zygomaticomaxillary and fronto-naso-ethmoido-orbital bone and epidural hematoma on the right temporal lobe of brain. Bony fragments compressing the optic nerve on lateral side was identified on computed tomography. Decompression of the optic nerve combined with evacuation of epidural hematoma has been performed via transfrontal craniotomy. The patient had complete recovery of visual acuity without any complications. The role of optic nerve decompression in the management of patients with traumatic optic neuropathy is discussed. Surgical indication is controversial and the procedure should be considered only within the context of the specific indication of the individual patient.

In this paper, We performed the human body dynamic modelling for the realistic animation based on the dynamical behavior of human body, and designed controller for the effective control of complicate human dynamic model. The human body was simplified as a rigid body which consists of 18 actuated degrees of freedom for the real time computation. Complex human kinematic mechanism was regarded as a composition of 6 serial kinematic chains : left arm, right arm, support leg, free leg, body, and head. Based on the this kinematic analysis, dynamic model of human body was determined using Newton-Euler formulation recursively. The balance controller was designed in order to control the nonlinear dynamics model of human body. The effectiveness of designed controller was examined by the graphical simulation of human walking motion. The simulation results were compared with the model base control results. And it was demonstrated that, the balance controller showed better performance in mimicking the dynamic motion of human walking.

The purpose of this study is to examine that the escape stair of high-rise buildings has to be designed as a left-handed stair(a stair being designed to turn left whicle we go down the ground floor) judging from fire-safety point of view. Most of Korean people are right-handers. In case of right-handers it was found that the occupant's escape speed using a left-handed stair is more convenient and fast than of a right-handed stair(a stair being designed to turn right while we go down the ground floor). But most of the escape stair of high-rise buildings in Korea was designed as a right-handed stair. The fire code therefore should be provided that the escape stair of high-rise buildings should be a left-handed stair.

In this paper, we proposed the spinning right-angle stereo vision system to center the shifted object on 3-dimensional image using a human eyesight-like, and the system is reconstructed with conventional stereo vision system. In this proposed system, the centering results of objects on the 3-dimensional image are very good, and we got the parameter ratios 89~112% for the real measurement values. Therefore, the suggested the spinning right-angle stereo vision system have a high possibilities to be applied to many industrial system parts and to be used for robot system, automatic system, and etc.

Purpose: This study aimed to derive a conceptual definition and attributes for nursing students' rights in clinical practice in South Korea. Methods: This concept-analysis study was conducted at a nursing school in South Korea. The participants were recruited using purposive sampling. The inclusion criteria were being a fourth-year nursing student and having two or more semesters of practical experience. The hybrid model used in this study had three stages. First, 12 studies were reviewed during the theoretical stage. Second, 10 in-depth interviews were conducted during the fieldwork stage. Third, in the analytical stage, the concept of nursing students' rights related to clinical practice was defined and the attributes were derived. Results: The analysis established five attributes of nursing students' rights: the right to learn, the right to be protected from infections and accidents, the right to be cared for and supported, the right to be respected, and the right to be recognized as a member of a nursing team. A key theme that emerged from this study was having the right to learn in a safe and supportive environment. Conclusion: It is necessary to develop a measurement tool based on the above five attributes and to verify its effectiveness.

To study on the assignment of the eight trigrams (八卦) in human body being based on based the number of HADO(河圖)-NAGSEO(洛書). Being based on the number of HADO(河圖)-NAGSEO(洛書) and the BEOK-HEE's diagram of eight trigrams order(伏羲次序圖), human being organ (five-Jang organs (liver, heart, spleen, lung and kidney), five organs (ear, eye, mouth and nose), provisional namely six entera for the process on intake, digestion, excretion of food (mouth, stomach, small intestine, large intestine, rectum, anus) are assigned eight trigrams (八卦). Eight trigrams(八卦) are attached to the based on the number HADO(河圖)-NAGSEO(洛書): 1-GEON(乾), 2-TAE(兌), 3-LEE(離), 4-JIN(震), 9-SON(巽), 6-GAM(坎), 7-GAN(艮), 8-GON(坤). And (八卦) are attached to the human being organs (five-Jang organs (live, heart, spleen, lung and kidney), five organs (ear, eye, mouth, nose, anus) : 1-GEON(乾)-left lung-left nose, 6-GAM(坎)-right kidney-right ear, 7-GAN(艮)-left heart-anus, 8-GON(坤)-right liver-right ear. Eight trigrams(八卦) are attached to the provisional namely six entera for the process on intake, digestion, excretion of food : the air(GEON 乾), the month(TAE 兌), the stomach(LEE 離), the small intestine(JIN 震), the large intestine(Son 巽), the rectum(GAM 坎), the anus(GAN 艮), the excrements(GON 坤). The BEOK-HEE's diagram of eight trigrams order(伏羲次序圖) means immutable order naturally. The process of the human being organs( five-Jang organs, five organs and six entera's digestion) is also unchangeable in region and program. Therefore we can set up the five-Jang organs, five organs and the process of six entera's digestion as the category of observation on the basis of BEOK-HEE's diagram of eight trigrams order(伏羲次序圖), and then we can arrange eight trigrams (八卦) on the five-Jang organs, five organs and the process of six entera's digestion.

A human gait study is required for the biomechanical design of running shoes. A tow-dimensional dynamic model was developed in order to analyze lower extremity kinematics and loadings at the right ankle, knee, and hip joints. The dynamic model consists of three segments, the upper leg, the lower leg, and the foot. Each segment was assumed to be a rigid body with one or two frictionless hinge joints. The lower extremity motion was assumed to be planar in the sagittal plane. A young male subject was involved in the gait test and his anthropometric data were measured for the calculation of segement mass and moment of inertia. The experimental data were obtained from three trials of walking at 1.2m/s. The foot-floor reaction data were measured from a Kistler force plate. The kinematic data were acquired using a three-dimensional motion measurement system (Expert Vision) with six markers, five of which were placed on the right lower extremity segments and the rest one was attached to the force plate. Based on the model and experimental data for the stance phase of the right foot, the calculated vertical forces reached up to 492, 540, and 561 N at the hip, knee, ankle joints, respectively. The flexion-extension moments reached up to 155, 119, and 33 Nm in magnitude at the corresponding joints.

Human can generate various posture and motion with nearly 350 muscle pairs. From the viewpoint of mechanisms, the human skeleton mechanism represents great kinematic and dynamical complexity. Physical and behavioral fidelity of human motion requires dynamically accurate modeling and controling. This paper describes a mathematical modeling, and dynamic simulation of human body. The human dynamic model is simplified as a rigid body consisting of 18 actuated degrees of freedom for the real time computation. Complex kinematic chain of human body is partitioned as 6 serial kinematic chains that is, left arm, right arm, support leg, free leg, body, and head. Modeling is developed based on Newton-Euler formulation. The validity of proposed dynamic model, which represents mathematically high order differential equation, is verified through the dynamic simulation.
