Objective : To investigate objectively the postoperative improvement of gait disturbance in patients with cervical myelopathy through a gait analysis. Patients and Methods : Ten patients who underwent cervical decompression and fusion for cervical myelopathy caused by spondylosis, OPLL, or concomitant hypertrophy of ligamentum flavum were studied. Preoperatively, gait disturbance was present in all patients. The patients were evaluated by gait analysis using three dimensional motion analyzer to collect data of linear and kinematic parameters before surgery, 1 week and 3 months after surgery. Statistical analysis of the related pre-and post-operative data were performed. Results : In the linear parameters, average value of cadence, walking speed, stride length, step time, width and double support were increased postoperatively compare to preoperative value. In the kinematic parameters, average value of knee flexion during initial swing phase, plantar flexion of ankle and range of motion of hip joint were increased as well. These differences were statistically significant(p<0.05). Conclusion : This study suggests that gait analysis can be used as a method of quantitative analysis of postoperative gait improvement in patients with cervical myelopathy.

Toegye pursues a life of pleasure, joy and nobility. Anyone who is a scholar shall feel a joy in learning and practicing. However, not everyone can enjoy true pleasure or true calling through self-cultivations. Everybody wants "a joy of distant friends' visitations." But most of Confucian scholars prefer forests as a place of learning and self-cultivation. Toegye especially likes a forest life and then gives same value to walking as to reading. "Not to be angry even if not recognized" must be a high stage of self-cultivation. Toegye does not pursue fame or glory and always resign into a country life. His life-time resignation makes him obtain great after-death fame and glory. Thus, nobody feels jealousy against him but adores him.

In this paper, we propose a parametric model for analyzing the motion information obtained from the acceleration sensors to measure the activity of the human body. The motion of the upper body and the lower body does not occur at the same time, and the motion analysis method using a single motion sensor involves a lot of errors. In this study, the 3-axis accelerometer is attached to the arms and legs, the body's activity data are measured, the momentum of the arms and legs are calculated for each channel, and the linear predictive coefficient is obtained for each channel. The periodicity of the upper body and the lower body is determined by analyzing the correlation between the channels. The linear predictive coefficient and the periodic value are used as data to measure the type of exercise and the amount of exercise. In the proposed method, we measured four types of movements such as walking, stair climbing, slow hill climbing, and fast hill descending. In order to verify the usefulness of the parameters, the recognition results are presented using the linear predictive coefficient and the periodic value for each motion as the neural network input.

This study aimed to examine the influence of physical environment, microclimate, and comfort on sustaining outdoor activities. This study has identified the main factors that influence sustaining outdoor activities as physical environment, comfort in the physical environment, microclimate and microclimate comfort. For analysis, the study conducted the investigation on pedestrian walkability during spring, summer and winter of the year 2017. The microclimate levels were also recorded at the same time. The method of logit regression analysis was used to analyze these outcomes. The result showed that the comfort and safety of the physical environment as well as the ideal climatic conditions, in terms of temperature, wind level, and solar insolation, were related to sustaining outdoor activities. Also, walking and shopping in the physical and climatic environment were the factors that were found to be more influenced than the act of remaining in a place and forming conversations.

As the urbanization progresses, the demand for parking in large cities surges compared with that for parking lots. However, the space for securing a parking lot in a large city is physically limited and a budget problem also arises. Therefore, a shared parking system that can utilize existing parking lots is becoming important. This study was carried out to analyze the parking area efficiently for the residents parking area. As a result of the questionnaire survey, it was the most frequent passage to work / commuting and business purposes. The most important factors in parking were 'Parking charge', 'Walking distance to the destination after parking', 'Parking lot searching time' Approximately 46 % of the respondents were female. As a result of the quantitative analysis of the factors influencing the potential use of the intention to use as a dependent variable, it was analyzed that the policy was effective to reduce the parking fee to less than 500 won per 10 minutes and take about 3-6 minutes to search.

The Korean Hanhyup broiler has commercialized native meat-type chicken. This study aimed to determine the effects of two types of litter material-sawdust and rice husk, and gender on the Korean Hanhyup broiler. Chicks (n=416) were randomly assigned in a $2{\times}2$ factorial design by type of litter material and gender. The behavior of chicken's was monitored continuously for 12 hours during the $1^{st}$ through $8^{th}$ week of age. The time spent on standing, sitting, and walking and the frequency of drinking, feeding, preening, dust bathing, flapping, and aggressive pecking, and pecking of chicken's behavior were recorded. The behavior of chickens during the starter (1 to 4 weeks) and finisher period (5 to 8 weeks) was compared to observe the changes upon maturity. Our results indicate that litter material type and gender have no effect on the behavior of chickens. However, aggressive pecking and pecking caused increment in the rice husk as compared to sawdust (P<0.05). Sawdust as litter material for bedding was found to be better than rice husk with respect to Korean Hanhyup broiler behavior.

Floating holograms are technologies that provide rich 3D stereoscopic images in a wide space such as advertisement, concert. In addition, It is possible to reduce the 3D glasses inconvenience, eye strain, and space distortion, and to enjoy 3D images with excellent realism and existence. Therefore, this paper implements a user gesture recognition system for manipulating a floating hologram characters that can be used in a small space devices. The proposed method detects face region using haar feature-based cascade classifier, and recognizes the user gestures using a user gesture-occurred position information that is acquired from the gesture difference image in real time. And Each classified gesture information is mapped to the character motion in floating hologram for manipulating a character action. In order to evaluate the performance of the proposed user gesture recognition system for manipulating a floating hologram character, we make the floating hologram display devise, and measures the recognition rate of each gesture repeatedly that includes body shaking, walking, hand shaking, and jumping. As a results, the average recognition rate was 88%.

Purpose : The purpose of this study was to examine the effect of task-oriented circuit training using unstable support surface on balance, gait ability, and balance confidence in subacute stroke patients. Methods : Forty-five patients with subacute stroke were randomly divided into the three following groups of 15: 1) TOCT-US group; task-oriented circuit training using unstable surface (experimental group 1), 2) TOCT-SS group; task-oriented circuit training using stable surface (experimental group 2), and 3) CON group; conventional physical therapy (control group). All patients participated in one of the three training programs for 6 weeks, 30 minutes per session, 3 times per week. Patients' balance ability was assessed using the BT-4, BBS (berg balance scale), TUG (time up and go test), and LOS (limit of stability). Gait speed was measured to examine gait ability. K-ABC (activities-specific balance confidence scale) was also used to assess the level of patients' confidence in daily activities. Results : After the intervention, the sway area in experimental groups 1 and 2 decreased, but that in the control group increased. Experimental group 1 showed significant improvement compared with experimental group 2 and the control group. BBS, TUG, and LOS scores of experimental group 1 were significantly improved compared with those of experimental group 2 and the control group. Also, gait speed significantly improved in experimental group 1 compared with experimental group 2 and the control group. Experimental groups 1 and 2 showed significant improvement in K-ABC scores after training. Conclusion : Patients with subacute stroke had significantly improved balance, gait, and level of confidence in performing activities of daily living following task-oriented circuit training using the unstable surface. This indicates that task-oriented circuit training using unstable surfaces can be an effective treatment method for the recovery of balance and gait in subacute stroke patients.
