Purpose: The purpose of this study was to analyze the effects of proprioceptive neuromuscular facilitation (PNF) patterns on electromyography (EMG) activity in the rectus abdominis, internal abdominal oblique, external abdominal oblique, and erector spinae according to position changes. Methods: Ten healthy adults volunteered to participate in the study. The subjects were required to complete exercises that followed two PNF extremity patterns, namely, an upper extremity extension-adduction-internal rotation pattern and a lower extremity flexion-adduction-external rotation pattern. The exercises were applied in the supine, side-lying, and sitting positions. Repeated measure one-way ANOVA and post-hoc Bonferroni correction were used to determine the influence of the patterns on muscle activity for each muscle, and descriptive statistics were then used to determine the local/global muscle ratios. Results: The upper extremity pattern had a significant effect on the rectus abdominis and erector spinae in the supine position, and on the internal oblique and external oblique in the sitting position (p<0.05). The median value for the internal oblique/rectus abdominis showed a high ratio of 2.05, and a high ratio of 1.01 was shown for the internal oblique/external oblique in the sitting position. The lower extremity pattern had a significant effect on the rectus abdominis in the side-lying position and on the internal oblique, external oblique, and erector spinae in the sitting position (p<0.05). The median value for the internal oblique/rectus abdominis showed a high ratio of 2.83 in the sitting position and a high ratio of 1.30 for the internal oblique/external oblique in the side-lying position. Conclusion: The PNF pattern increases local muscle activation in an unstable position. Therefore, when the pattern is used for intervention purposes, trunk stability and varied position changes should be taken into account.

Purpose: The purpose of this study is to analyze the effect of the arm extension pattern of proprioceptive exercise program on the muscle activity of the opposite lower extremity. Methods: In this study, electromyogram MP150(Biopac system, USA) was applied to 20 healthy male subjects. Arm extension-adduction-internal rotation pattern was applied within initial, mid and end range in sling position and supine position for measurement. And the effect on the activity of rectus femoris and tibialis anterior muscle of the opposite lower extremity was compared and analyzed. Results: The results of this study were summarized as follows: First, there was a statistically significant difference of the activity of the tibialis anterior muscle within the Initial range in sling position and supine position(P<0.05). Second, there was a statistically significant difference of the activity of the tibialis anterior muscle within the end range in sling position and supine position(P<0.05). Conclusion: Rectus femoris and tibialis anterior muscles shows the higher activity in the supine position than in the sling position. Therefore, the supine position is more appropriate than the sling position to make irradiation on lower extremity muscle with the extension pattern.

This study was attempted to individualize upper and lower incisor position appropriate to individual characteristic dento-facial pattern. Lateral cephalometric radiographs of 75 Korean adults with normal occlusion and good facial profile whose ages were over 17 years were traced, digitized, and statistically analysed. The results of this study were as follows; 1. All cephalometric measurements of incise. position and dento-facial pattern for normal occlusion showed wide range of variation. 2. There were no significant differences of incisor position between males and females. 3. Lower incisor position was highly correlated with ANB, N-A-Pog and SN/Mand. pl. angle and upper incisor position, with ANB, N-A-Pog and SN/Occ. pl. angle. 4. Multiple regression equations were established to individualize incisor position appropriate to individual characteristic dento-facial pattern. ANB and N-A-Pog angle were selected as the significant guiding variables affecting upper and lower incisor position. 5. Lower incisor position such as $\bar{1}$ to SN, $\bar{1}$ to occlusal plane and $\bar{1}$ to NPog(mm) and upper incisor position such as $\underline{1}$ to SN, $\underline{1}$ to palatal plane, $\underline{1}$ to NA, $\underline{1}$ to NA (mm) and $\underline{1}$ to NPog(mm) could highly predicted from the variables of dento-facial pattern.

This paper researches location estimating method in CDMA system. Previously proposed positioning algorithms are difficult to estimate accurate position in indoor environments, and possible to limited position. This paper proposes enhanced algorithm using received PN pilot signals from base stations to enhance previous algorithms. For estimating position, we set the threshold value and use over the threshold value in received signals. After selecting signals, we estimate position using TDOA algorithm. And the cases which TDOA algorithm cannot use to estimate position, we use Pattern Matching algorithm. The proposed method system showed the improved performance in estimating parameters and locating positions by computer simulations.

In this study the preference degree of a Dangcho pattern with priority given to demographic variables was examined. The results was that demographic variables have influence on the preference degree of a Dangcho pattern. The continual arrangement pattern of a stylistic type was shown as the pattern that men in their 40s and over most prefer. The continual arrangement pattern of a realistic type was shown as the pattern that men in their 40s and over and women in their 50s and over most prefer. The continual arrangement pattern of a geometrical type was shown as the pattern that men working on a sales, service, production position and women in their 50s most prefer. The single arrangement pattern of a stylistic type was shown as the pattern that college men in their 20s, men in their 50s and women working on a sales, production, service position most prefer. The single arrangement pattern of a stylistic type of a realistic type was shown as the pattern that men in their 40s working on a sales, service, production position and college women in their 20s most prefer. The single arrangement pattern of a geometrical type was shown as the pattern that most of people prefer.

Grip strength is an objective indicator for evaluating the functional movement of upper extremities. Therapists have been using it for a long time as an excellent barometer for evaluating the therapy process, therapeutic effects and prognosis of patients with injuries in upper extremities. This study investigated the effects of extensor pattern position and elastic taping of non-dominant hand on the grip strength of dominant hand among general adults. The subjects of this study were 23 males and 7 females from physical therapy departments of 3 Universities located in Busan who agreed to participate in the experiment and the resultant data were analyzed using SPSS version 12.0. The results of the study were as follows. First, there was a significant difference between the grip strength of dominant hand when the non-dominant hand was at the neutral position and that when the non-dominant hand was at the extensor pattern position and both hands were at the maximum strength simultaneously (Bonferroni-corrected p<.001). Second, there was a significant difference between the grip strength of dominant hand when the non-dominant hand was at the neutral position and that when the elastic taping of non-dominant hand was applied (Bonferroni-corrected p<.001). Third, there was no significant difference between the grip strength of dominant hand when the non-dominant hand was at the extensor pattern position and both hands were at the maximum strength simultaneously and that when the elastic taping of non-dominant hand was applied. The irradiation effects through the extensor pattern position of non-dominant hand and application of the elastic taping to non-dominant hand showed significant results in improving the maximum grip strength of dominant hand. This finding could be suggested as the probability for the indirect treatment of the upper extremities of hemiplegia and orthopedic patients due to the long-term fixing of upper extremities.

The suitability of the pattern manufactured with the development figure was considered by reviewing the development conditions that can be directly connected to the basic pattern in the human body surface development figure with the cast bandage method. The method to prepare the sleeve basic pattern was based on the cylindrical surface development method, and the sleeve basic pattern covering the 45 and 90 degrees momentum of the arm-movement was made by using the cast-type body surface development figure prepared with the horizontal line of the sleeve hem placed horizontally in the plan and by combining the cast-type body surface development figure in the standing position with the figure in the moving position. The test clothing was prepared with the sleeve pattern adding the bodice pattern in the standing position and the momentum and was worn on the FRP replica. The relationship theory of the body surface development figure with the pattern was derived by reviewing the suitability from the wearing state. The sleeve-cap height of the sleeve basic pattern resulted in about 80% in the standing position when the needs for a physical activity are 45 degrees and the about 50% when the needs for a physical activity are 90 degrees. The additional size of the diagonal length of the sleeve-cap could be set as "0" if the sleeve-cap height is low by 50% and as 50% of the additional size in the standing position if the sleeve-cap height is 80%.

Recent increasing demand on the indoor localization requires more advanced and hybrid technology. This paper proposes an application of the hybrid indoor localization method based on a position-coded pattern that can be used with other existing indoor localization techniques such as vision, beacon, or landmark technique. To reduce the pattern-recognition error rate, the error detection and correction algorithm was applied based on Hamming code. The indoor localization experiments based on the proposed algorithm were performed by using a QCIF-grade CMOS sensor and a position-coded pattern with an area of $1.7{\times}1.7mm^2$. The experiments have shown that the position recognition error ratio was less than 0.9 % with 0.4 mm localization accuracy. The results suggest that the proposed method could be feasibly applied for the localization of the indoor mobile service robots.
