지진의 영향으로 인한 지각변동 모니터링은 지구물리 및 측지학 분야에서 중요한 연구대상이다. 본 연구에서는 지난 3월 11일 오후 2시 46분 경 발생한 일본 지진에 따른 지각변동 영향을 분석하기 위해 일본지역의 9개 IGS 상시관측소를 대상으로 지진 발생 전 후의 자료를 정밀절대측위로 처리하고, 상시관측소의 위치 해석을 통해 지진으로 인한 일본지역의 지각변동을 분석하였다. 지각변동 모니터링 결과, 일본지역의 지진 변위량과 지진 전 후 지각 변동의 변화를 정량적으로 제시할 수 있었다. 지진 전 후 일본지역의 지각변동이 기존과 다른 양상을 나타내고 있음을 볼 때, GPS 관측자료 해석을 통한 지속적인 지각변동 모니터링이 필요할 것이다.

Objective: Bilateral movement training is an effective method for upper extremity rehabilitation of stroke. An approach to induce bilateral movement through functional electrical stimulation is attempted. The purpose of this study is to develop an EMG-triggered functional electrical stimulation device for upper extremity bilateral movement training in stroke patients and test its feasibility. Design: Feasibility and Pilot study design. Methods: We assessed muscle activation and kinematic data of the affected and unaffected upper extremities of a stroke patient during wrist flexion and extension with and without the device. Wireless EMG was used to evaluate muscle activity, and 12 3D infrared cameras were used to evaluate kinematic data. Results: We developed an EMG-triggered functional electrical stimulation device to enable bilateral arm training in stroke patients. A system for controlling functional electrical stimulation with signals received through a 2-channel EMG sensor was developed. The device consists of an EMG sensing unit, a functional electrical stimulation unit, and a control unit. There was asymmetry of movement between the two sides during wrist flexion and extension. With the device, the asymmetry was lowest at 60% of the threshold of the unaffected side. Conclusions: In this study, we developed an EMG-triggered FES device, and the pilot study result showed that the device reduces asymmetry.

Objective: This study aimed to determine the effect of wrist and trunk weight loading using sandbags in stroke patients in order to provide the quantitative data for enhancement of gait movement. Method: Twelve stroke patients, who have been diagnosed with hemiplegia over a year ago, were participated in this study. All subjects were asked to perform normal walking [N], wrist sandbag walking [W], wrist & trunk sandbag walking [WT], and both wrist sandbag walking [B] and both wrist & trunk sandbag walking [BT], respectively. Eight infrared cameras were used to collect the raw data. Gait parameters, arm swing, shoulder-pelvic kinematics, and lower extremity joint angle were calculated to examine the differences during walking. Results: As a result, there were no significant differences in the gait parameters, shoulder-pelvis, and lower extremities joint angles, but significant differences were found in the range of motion and the anteversion in arm swing. Conclusion: Wrist and trunk weight loading using sandbags affected the movement of the upper extremities only while it did not affect the movement of the lower extremities. It implies that it can reduce the risk of falling caused by a sudden movement change in lower extremities. In addition, the wrist and trunk weight loading using sandbags can induce changes in movement of the upper extremities independently and contribute to functional rehabilitation through resistance training.

Movement technique is comprised of the movement status of the circulation differentiation rate (CDR) and rotation differentiation rate (RDR) on the shiver movement form. Condition of the differentiation rate by the shiver movement form is to be modified the teetering movement system. As to fix the movement of signal on the material of body, we compared a shiver value of the circulation differentiation rate on the circulation state. The concept of rotation differentiation rate was identified the reference of rotation differentiation signal and rotation differentiation signal by the rotation state. For detecting a alteration of the CDR-RDR of the maximum and average in terms of the movement form, and shiver movement value that was a shiver value of the top alteration of the Top-ф$_{MAX-AVG}$ with $12.80{\pm}1.27units$, that was a shiver value of the peripheral alteration of the Per-ф$_{MAX-AVG}$ with $4.38{\pm}1.15units$, that was a shiver value of the limbus alteration of the Lim-ф$_{MAX-AVG}$ with $1.65{\pm}0.25units$, that was a shiver value of the center alteration of the Cen-ф$_{MAX-AVG}$ with $0.25{\pm}0.01units$. The teetering movement will be to assess at the ability of the movement form for the control degree of differentiation rate on the CDR-RDR that was shown the circulation and rotation form by the differentiation rate system. Teetering differentiation system was modified of a form by the special movement and was included a shiver data of teetering movement rate.

Objectives The purpose of this study was to improve the comfort of daily life such as reduction of headache and increase of movement of neck by using muscle relaxation approach and joint movement approach for office worker with tension type headache of foward head posture sitting over 5 hours. Methods For this, 9 male and 15 female participated in the foward head posture with tension type headache. Each group consisted of 3 male and 5 female. Groups are divided into groups, such as muscle relaxation therapy, joint movement therapy, muscle relaxation and joint movement therapy. After intervention for each group for a month, we measured neck movement and head disability index and neck disability index 2 week. SPSS 23.0 (IBM Corp., Armonk, NY, USA) was used for data analysis. The one-way repeated analysis of variance (ANOVA), one-way ANOVA, compared t-test was used for statistical analysis. Results Three intervention groups have brought improvements in neck movement and daily life comfort. There is significant difference in the improvement of neck extension and change in neck disability index between 2 and 4 weeks in the joint movement approach compared to muscle relaxation approach, muscle relaxation and joint movement approach. Conclusions Office workers are exposed to tension type headache. However, muscle relaxation approach and joint movement approach can improve neck movement and daily life comfort.

Due to the development of information technologies and new businesses related to moving objects, the need for the storage and analysis of moving object data is increasing rapidly. Moving object data have a spatiotemporal nature which is different from typical business data. Therefore, different methods of data storage and analysis are required. This paper proposes a multidimensional data model and data visualization to analyze moving object data efficiently and effectively. We expect that decision makers can understand the movement pattern of moving objects more intuitively through the proposed implementation.

The purposes of this study were to draw out the situational problems of the community based NGO (Non Governmental Organization) movement and to suggest development strategies for NGO movement in Korea. The study was conducted through extensive review of literature and analysis of the related data. The major findings of this study were as follows; As the development of democracy and localization process were in progress, the community based NGO movement was also developing quantitatively, however not yet qualitatively. The NGO Times Net, a internet newspaper for NGOs revealed that the number of community based NGO was 3,397 as in 2004, which was 5 times larger than 597 central based or Seoul located NGOs. However, some of the problems identified were lower participation of local people, quality of the movement compare to the original purposes of the movement, and the problems in local leadership, etc. In order to overcome various problems, this study suggested some strategies for development such as enhancement of civil education, expansion of voluntary spirits, financial support for NGOs, better mutual understanding among the GOs (Government Organizations), POs(Profit Organizations) and NGOs. Self evaluation and innovative strategies will be needed for further development of NGO movement in Korea.

This paper proposes the concept of "virtual sensor data" and its application for real time obstacle avoidance. The virtual sensor data is virtual distance which takes care of the movement of the obstacle as well as that of the robot. In practical application, the virtual sensor data is calculated from the odometry data and the range sensor data. The virtual sensor data can be used in all the methods which use distance data for collision avoidance. Since the virtual sensor data considers the movement of the robot and the obstacle, the methods utilizing the virtual sensor data results in more smooth and safer collision-free motion.
