This presents a motion and force estimation system of human fingers by using an Electromyography (EMG) sensor module and a data glove system to be proposed in this paper. Both EMG sensor module and data glove system are developed in such a way to minimize the number of hardware filters in acquiring the signals as well as to reduce their sizes for the wearable. Since the onset of EMG precedes the onset of actual finger movement by dozens to hundreds milliseconds, we show that it is possible to predict the pattern of finger movement before actual movement by using the suggested system. Also, we are to suggest how to estimate the grasping force of hand based on the relationship between RMS taken EMG signal and the applied load. Finally we show the effectiveness of the suggested estimation system through several experiments.

This study is about researching DongEuiBoGam by analysing with pattern identification of modern Traditional Korean medical patholgy as more logical, systematic and standardized theory. Disease pattern mechanisms of essence, spirit, qi and blood in NaeGyungPyeb of DongEuiBoGam are these. In Essence, this explain mechanism of disease patterns those are seminal emission, dream emission, spermatorrhea, white ooze. These disease pattern's mechanisms are kidney yang deficiency, kidney yin deficiency, heart yang deficiency, heart yin deficiency, heart qi deficiency, spleen qi deficiency and so on. On viewpoints of viscera and bowels they are related with heart, kidney, spleen. And most of them are deficiency from deficiency-excess Pattern Identification. Classifying disease pattern of qi is about upward, downward movement and more concentrated deficiency than excess pattern. Fright palpitations can be classified heart deficiency with timidity, heart blood and qi deficiency, heart qi deficiency, heart blood deficiency, heart qi movement stagnation, water qi intimidating the heart, phlegm-fire harassing the heart, phlegm clouding the pericardium, and so on. Palpitations can be classified heart blood deficiency, heart yin deficiency, heart deficiency with timidity, heart spleen blood deficiency, spleen qi deficiency, phlegm-fire harassing the heart, intense heart fire, and so on. Forgetfulness can be classified heart spleen blood deficiency, heart spleen qi deficiency, kidney essence deficiency, heart qi deficiency, non-interaction between the heart and kidney, etc. for deficiency pattern, phlegm clouding the pericardium for excess pattern. In Blood just say inside bleeding pattern's category, there are nose bleeding, flopping syncope, qi counterflow, blood vomiting, hemoptysis, spitting of blood, bloody stool, hematuria, and so on. Like these, this study identify pattern of disease in DongEuiBoGam by mechanism of disease theory.

Purpose: The purpose of this study was to investigate the effects of neck patterns in proprioceptive neuromuscular facilitation (PNF) for neck movement and the neck disability index (NDI) among adults with forward head posture. Methods: Thirty-nine subjects were randomly assigned into two groups. Subjects in the proprioceptive neuromuscular facilitation exercise group (PNFG, n = 20) received 20 minutes of PNF neck pattern (flexion-Rt. lateral flexion-Rt. rotation followed by extension-Lt. lateral flexion-Lt. rotation) 3 times weekly for 4 weeks. Outcomes were measured using absolute rotation angle (ARA), anterior weight bearing (AWB), range of flexion and extension motions (RFEM), and neck disability index (NDI) methods before and after the 4-week intervention period. Results: There were significant effects for the PNFG, pre- and post-intervention, in ARA, AWB, RFEM, and NDI. There were significant differences in ARA, AWB, RFEM, and NDI compared with CG. Conclusion: The results of this study suggest the PNF neck pattern could be beneficial for adults with forward head posture.

This study is to research on the rate of expansion or contraction according to movement of the lower body of the man their twenties using Rapid Form software. And aim of this study is to get information of ease allowance in developing slacks pattern using 3D body surface scan data through comparison with existing slacks patterns. Considering on the contraction and expansion according to movement, it need to set the more ease allowance in hip circumference than waist circumference, and the more ease allowance in back hip width than front hip width in slacks. In crotch length, the length of front crotch is revealed contraction but the length of back crotch is revealed expansion. It is desirable lowering front waist line and raising back waist line to possess ease allowance in back crotch area. The length of side seam is revealed a little expansion but the length of inseam is showed a great expansion. To develop slacks pattern of scientific approach using 3D body surface scan data, it need to analysis the rate of expansion and contraction of the lower body based on the movement, shear deformation, slip in fabrics and skin, or in fabrics and fabrics, and slip down from waist line.

Currently, a lot of people are aware of their health and well-being, so they are concerned about their healthcare. 'Taekwondo' is one of the popular sports that Korean people are passionate about Taekwondo has also become globalized. The uniform of Taekwondo is gaining importance. Taekwondo involves a lot of movement, hence the pattern should facilitate the movement. In addition Taekwondo uniform pattern should meet the demands of functionality, fit and consumer design preferences. This study aimed to provide the basic data for development of Taekwondo uniform pattern based on design preferences and functionality to wearer satisfaction. The result of this method indicated fit and design details. Also, the length of pants, top, and sleeve was too wide, which has to more fitted for both of genders. For females, the breakpoint was too low, which requires some increase to make females feel more secure. In conclusion, the results of this study indicated that in order to increase 'Takwondo' value, Taekwondo uniform is required to be more fashionable and comfortable to wear, which could influence other sports wear.

Air pollution inventories are aggregated around south-eastern part of the Korean Peninsular including Busan, Ulsan, and Changwon cities. Because densely populated cities are concentrated in this region, air pollutants emitted from one of these cities tend to be impacted on the air quality of other cities. In order to clarify the seasonal movement pattern of emitted particles, several numerical simulations using WRF/FLEXPART were carried out. Four cases were selected for each season. The Weather Research and Forecasting model (WRF) reproduced atmospheric flow fields with nested grids. The seasonal pattern of air mass of study area was determined by backward and forward trajectories. As a result, the air parcel moves from northwest to southeast due to northwesterly winds in spring and winter. Also air parcel transports from south to north in summer, and moves from west to east. Because the air mass moves differently in each season, these characteristics should be considered when performing air quality analysis.

With the growing interest in pet dogs and pet dog's wear I used this study to compare and analyze the pattern used by each supplier and developed a new pattern for pet dogs' wear which is appropriate for pet dogs' body lines and movement. Test subjects were 91 pet dogs in Busan and after comparing 3 patterns from different suppliers, I developed the pattern reflecting pet dogs' body shapes and movement. Results are as follows; 1) As a result of analyzing measurements, it was found that pet dogs motion in walking on four feet, is different from that of people on two feet. For center measurements, their waist to bust length is longer than their waist to back length. The result of analysis shows that bust circumference impacts most other measurement results and it seems that better results are achieved if the bust line is taken into consideration when measuring bust back length, bust front length, neck base circumference, front leg arc, the length between lateral shoulder etc. 2) As a result of comparing suppliers' patterns, it was discovered that each supplier has different sizes for the same patterns and those sizes are not standardized across the board. Even if the same size of pattern was actually used in the production of pet dogs' wear by the individual companies, there were many variations in size for each item. 3) To develop a more standard pattern of pet dogs' wear, I collected and analyzed 3 patterns from each supplier and designed a new pattern, revising it three times. After test-wearing of the experimental pattern and the studied patterns, and comparing and analyzing the results, the studied pattern had similarly better estimation than the experimental one.

A clinical study about painful manifestation on lumbar with regard to movement change of trunk The purpose of this study is to present the basis of low back pain therapy which is close examined of back muscle that is the main reason for that case of back pain when trunk rotation, flexion and extension. Therefore this study, which is based on literature review and clinical experience, has tried to figure out that back pain which is considered to be significant for the most increasing time, posture, motion, painful area, involved muscle have any influence on trunk rotation, flexion and extension This study has done with the patients in oriental rehabilitation clinic, K-oriental hospital, from Jan, 2003 to Dec, 2003. Total cases were 145(male:$39\%$-52 patients, female:$64.1\%$-93 patients) those who complained lumbosacral pain with radiating that makes patient unable to bending or extending the trunk. And they were surveyed retrospect way, checking the medical record and that of therapist. Results are as followings. 1. For sprain patient, $34.5\%$ complained pain on extension, and among them, the most remarkably, patients who did right rotation extension pattern were $20\%$. Herniated disc patient shows greater limit on flexion when trunk moves bending route, but right rotation with extension pattern shows the most limitation on flexion-extension according to the rotation of trunk 2. Cases of morning back pain($60.5\%$) showed high value on right rotation extension pattern($18.6\%$), right rotation flexion pattern($16.3\%$) but did not show big difference on left flexion and extension pattern 3. Patients those who complain pain on sitting position showed highest value each left, right $14.6\%$ of left and right rotation extension pattern 4. Among extension painful patient, there showed highest value of each $32.5\%$ on right rotation extension pattern, and $20.0\%$ on right rotation flexion pattern. 5. Tenderness distribution of quadratus lumborum showed $34.5\%$ on right rotation extension pattern, $20.7\%$ on left rotation extension pattern, and that of iliopsoas muscle at right rotation flexion pattern showed right muscle $20.0\%$, left $50.0\%$ Derived from the results of survey above, for sprain and HIVD patient showed greatest pain on right rotation pattern, for pain plus patient on right rotation extension among those who has extreme pain on sitting in the morning described tenderness on right quadratus lumborum, and those who complain pain on left rotation extension described tenderness on left lumborum the most Decisively, it is possible to figure out the problem muscle that involved when I found the time, position, motion that aggravating and painful area. Therefore this study would be expected to be able to be a useful clinical materials on diagnosis and therapy of low back pain.

This study aims to develop sleeve pattern of tailored jacket which shows seamlessly beauty of females in their twenties who have relatively smaller change of body compared people of other ages and has outstanding functional operation. So we selected a pattern of manufacturer who received highest score after evaluating wearing condition of three types of jacket in the industry, whose targets are career women in their twenties and then tested its appearance and functional operation of 6 experimental jackets with armhole depth of B/4 and B/4-1(cm) along with sleeve cap height of A.H/3, A.H/3+1, A.H/3+2. As a result, the pattern which has good result of external appearance evaluation were sleeve with armhole depth of B/4-1 and sleeve cap height of A.H/3+2 as well as sleeve with armhole depth of B/4-1 and sleeve cap height of A.H/3+1. The pattern of good result for movement adaptation were sleeve with armhole depth of B/4-1 and sleeve cap height of A.H/3 as well as sleeve with armhole depth of B/4 and sleeve cap height of A.H/3. So we could find that the larger is the armhole depth and height of sleeve, the better influence on adaptability of jacket it makes and that the smaller is the armhole depth and height of sleeve, the better influence on movement adaptability of jacket it makes. It has been proved that armhole depth of tailored jacket of females in their twenties doesn't affect significantly on its appearance when designing it but it makes good influence on movement adaptability when experimental clothing has armhole depth of B/4-1and that sleeve cap height of A.H/3 that is 1cm shorter than A.H/3+1 which is used in industry makes good influence on appearance and functional operation.
