The purpose of this study was to investigate the effects of virtual reality (VR) therapy with compensation inhibition and feedback (CIF) on upper extremity function in chronic stroke patients. Seven chronic stroke patients participated in this study, which was a randomized controlled trial with a crossover design. Self upper extremity exercise, conservative VR therapy, and VR therapy with CIF were performed for one hour per session, 5 times per week, over a 3 week period. The main outcome measures involved range of motion (ROM) including shoulder, elbow, and wrist joints, a Manual Function Test (MFT), and a Motor Activity Log (MAL). Data were calculated as posttest and pretest changes in every session and were analyzed using Friedman and Wilcoxon signed-rank tests at p<.05. The results were as follows: 1) Statistically significant increase in ROM measurements of shoulder and elbow joints were seen with VR therapy with CIF compared to VR therapy and self upper extremity exercise (p<.05), whereas no significant increasing was noted for the wrist joint (p>.05). 2) Statistically significant increase in the MFT was seen with VR therapy with CIF compared with VR therapy and self upper extremity exercise (p<.05). 3) VR therapy with CIF also resulted in statistically significant increase in both activity of use (AOU) (p<.05) and quality of movement (QOM) (p<.05) on the MAL test when compared with VR therapy and self upper extremity exercise, respectively. In conclusion, VR therapy with CIF was more effective than conservative VR therapy and self upper extremity exercise in improving the upper extremity function in hemiplegic patients with chronic stroke.

This study examined the types and cooking methods for dasik (traditional pressed sweet), as recorded in 16 old Joseon dynasty (1392-1909) studies. The ingredients used in dasik during the Joseon dynasty were categorized into cereal powders, tree fruits, flower powders, root clods, dry-fish beef powders, and vegetables. In the early, middle, and late eras of the Joseon dynasty, $1^{st}$ set (two, five, and 70 kinds of dasik), $2^{nd}$ set (two, four, and 16 kinds of dasik) were prepared using cereal powders, and during the middle and late eras of the Joseon dynasty one and 22 kinds of dasik were prepared using tree fruits. During the late eras of the Joseon dynasty, seven kinds of dasik were prepared using flower powders, 11 kinds of dasik were prepared using root clods, 12 kinds of dasik were prepared using dry-fish beef powders, and two kinds of dasik were prepared using vegetables. The frequency of the ingredients were in the order of Huek-im (黑荏), Hwang-yul (黃栗), Jin-mal (眞末), Song-wha (松花), and Nok-mal (菉末) during the Joseon dynasty. To prepare dasik, the ingredients were mixed with honey, soy sauce, sesame oil, pepper, and water or ground and shredded to prepare for pressing and for abstract dasik, respectively. The appearance and taste of dasik varied, thereby resulting in nutrient supplementation, as the types of ingredients increased throughout the Joseon dynasty. This observation may be associated with the commercial industrial development that prevailed during the late Joseon dynasty. Further investigation will be conducted on the recipes and ingredients recorded in these old studies to develop a standardized recipe for the globalization of dasik.

The purpose of this study was to investigate the effects of occupation-based bilateral upper extremity training and transcranial direct current stimulation on upper limb function in stroke patients. The study group was divided into 13 experimental groups with occupation-based bilateral upper extremity training and transcranial direct current stimulation, and 13 controls with only occupation-based bilateral upper extremity training. A total of 4 weeks, 50 minutes, 5 times a week conducted, the patients were tested with Canadian Occupational Performance Measure(COPM), Accelerometer, Fugle-Meyer Assessment(FMA), and Motor Activity Log(MAL). As a result of the study, the experimental group and the control group showed significant improvement in both occupation satisfaction and performance, usage of the affected side and the tendon side, recovery of upper limb function, and quality of movement, In particular, the experimental group showed a significant difference in the amount of the affected side than the control group. Therefore, it was found that the combination of occupation-based bilateral upper extremity training and transcranial direct current stimulation had a positive effect on the recovery of upper limb function in stroke patients.

This research investigates the influences of distributed generations (DG), which are interconnected to the bus by the dedicated lines, on the overcurrent relays (OCR) of the neighboring distribution feeders and also proposes a novel method to reduce the negative effects on the feeder protection. Due to the grid connected DG, the entire short-circuit capacity of the distribution networks increases, which may raise the current of the distribution feeder during normal operations as well as fault conditions. In particular, during the switching period for loop operation, the current level of the distribution feeder can be larger than the pickup value for the fault of the feeder's OCR, thereby causing the OCR to perform a mal-operation. This paper proposes the adaptive setting algorithm for the OCR of the distribution feeders having the neighboring dedicated feeders for the DG to prevent the mal-operations of the OCR under normal conditions. The proposed method changes the pickup value of the OCR by adapting the power output of the DG monitored at the relaying point in the distribution network. We tested the proposed method with the actual distribution network model of the Hoenggye substation at the Korea Electric Power Co., which is composed of five feeders supplying the power to network loads and two dedicated feeders for the wind turbine generators. The simulation results demonstrate that the proposed adaptive protection method could enhance the conventional OCR of the distribution feeders with the neighboring dedicated lines for the DG.

Purpose: The intention of this study was to investigate the effects of modified constraint-induced movement therapy (mCIMT) with bilateral arm training (BAT) on the motor performance and daily activity performance of individuals with chronic hemiparetic stroke. Methods: Sixteen subjects one year after stroke participated in this study with a control group; the pretest-posttest method was used. The subjects were randomly allocated into two groups: combination of bilateral arm training and modified constraint-induced movement therapy (n=8), and modified constraint-induced movement therapy (n=8). The mCIMT group received therapy for 90 minutes in 3 sessions per week over a period of 4 weeks. The patients receiving a combination of mCIMT and BAT were treated for the same period and frequency. The results were evaluated using the Fugl-Meyer Assessment, Action Research Arm Test (ARAT), and Motor Activity Log-Amount of Use, and Quality of Movement (MAL-AOU, QOM) assessment tools. Results: The Fugl-Meyer Assessment showed that hand and wrist performance improved significantly more in the mCIMT group than in the Combination group (p<0.05). Result from the ARAT assessment showed greater scores for gross movement in the combined group than in the mCIMT group (p<0.05). The MAL-AOU showed that there was greater improvement in the combined group than in the mCIMT group (p<0.05). Conclusion: The forced use of the more affected side can be important for the enhancement of upper extremity performance for chronic hemiparetic stroke patients during their daily activities.

In accordance with wide spread of personal computer and the expansion of network access, the use of internet has been popular and communication by text message is much more normal than that of voice and image. Accordingly, the side effect of communication language brings about gap between diverse social class, the isolation of communication between generations, abusive expressions, obstacles of juvenile mental development and so on. It appears by the form of slang and vulgar word and has a negative effect on education of mother tongue and usage of children's real language. To deal with these problems, we developed new web-based education system through the analysis of learners' requirement; "Barun Mal, Goeun Mal class". So we verified its efficiency to apply to real class. We also found that this system increased the learners' interest and educational effectiveness. Also, this system contributed to the proper use of language.

While conventional interferometric SAR (InSAR) technique is an excellent tool for displacement observation, it is only sensitive to one-dimensional deformation along the satellite's line-of-sight (LOS). Recently, a multiple aperture interferogram (MAI) technique has been developed to overcome this drawback. This method successfully extracted along-track displacements from InSAR data, based on split-beam InSAR processing, to create forward- and backward- looking interferograms, and was superior to along-track displacements derived by pixel-offset algorithm. This method is useful to measure along-track displacements. However, it does not only decrease the coherence of MAI because three co-registration and resampling procedures are required for producing MAI, but also is confined to a suitable interferometric pair of SAR images having zero Doppler centroid. In this paper, we propose an efficient and robust method to generate MAI from interferometric pair having non-zero Doppler centroid. The proposed method efficiently improves the coherence of MAI, because the co-registration of forward- and backward- single look complex (SLC) images is carried out by time shift property of Fourier transform without resampling procedure. It also successfully removes azimuth flat earth and topographic phases caused by the effect of non-zero Doppler centroid. We tested the proposed method using ERS images of the Mw 7.1 1999 California, Hector Mine Earthquake. The result shows that the proposed method improved the coherence of MAI and generalized MAI processing algorithm.
