  • A clothing-erogonomics study was performed to investigate the difference of the upper arm skin skin surface and the relationship among the three aspects of upper arm (height of sleeve rap, sleeve width and armhole girth) by changing arm movements. Plaster cast was used for this experimental research. Arm movements consist of 9 types; just carmly standing on ($0^{\circ}$), and each 4 types ($45^{\circ},\;90^{\circ},\;135^{\circ},\;180^{\circ}$) to the vertical direction in front and in side. The results were as follows; 1) As the arm-movement angle increased, the height of sleeve cap decreased and that ratio was largest in the portion A-B3. 2) The steeve width was enlarged with the increment of movement angle in all portions of upper arm except B1-B5. 3) As increasing the movement angle, the whole armhole girth decreased and the ratio o(front armhole girth (F-A) was larger than that of back. 4) In the vertical direction in front, the height o( the sleeve caps was larger, the sleeve widths were smaller than in the vertical direction in side in all movement types, but there was no significant difference in arm-hole girth between the two cases. 5) There were significantly negative relationships between measurements in height of sleeve cap and those in sleeve width, and also between those in height of sleeve cap and in arm-hole girth. And significantly positive relationships were found between neasurements in height of sleeve cap and those in arm-hole girth.

  • Background: The purpose of this study was to investigate the effects of ipsilateral and contralateral load changes during single-leg standing on the leg muscle activities of healthy people. Design: Randomized controlled trial. Methods: For all the subjects, a load was randomly applied to the ipsilateral or the contralateral side. While the load was applied, the subject raised a hand and then performed single-leg standing for 10 seconds using the dominant side. Results: During single-leg standing, the muscle activity of the gluteus medius, peroneus longus on the supporting side increased statistically significantly when an upper limb load was applied contralaterally, but no statistically significant differences were detected in the muscle activities of the tibialis anterior and the gastrocnemius using a test of within-subjects effects. Conclusion: It can be seen that muscle activities increase during exercise when the amount and frequency of a load are increased and when the same load is applied to different sides of the body. Such muscle activity increases may be applied to change the intensity of exercise when one is in a static posture, such as during single-leg standing.

  • In this research a Self-Standable mobile Robot with standing arms based on an Wheeled Inverted Pendulum is developed. Almost existing mobile robots have wide planar shape that is statistically stable and it is sometimes hard for them to run or steer on a narrow road. A Wheeled Inverted Pendulum based mobile robot has vertical shape that is upright-running and easily steering on a narrow road. It, however, requires actively balancing control and never restores the shape once it falls down. This research develops a Self-Standable mobile robot which equips standing arms and is able to change its chassis' posture freely from planar to vertical shape or vice versa.

  • 연구배경 : 척추의 이상굴곡 등으로 신장을 정확히 측정할 수 없는 환자에서 정상폐활량을 추정하기 위해서는 양팔벌린 손끝길이를 측정하여 신장을 예측한다. 연령을 고려하지 않고 고정된 비(AS/Ht ratio)를 이용하는 방법과 연령을 고려한 회귀방정식을 이용하는 두가지 방법이 있으며 이는 인종에 따라 다르다고 알려져있다. 대상 및 방법 : 우리나라 성인여성에서 양팔별린 손끝길이와 신장 그리고 연령과의 관계를 알아보고자 울산광역시에 거주하는 20-69세의 성인여성중 연령별로 표본추출된 381명(평균연령 $46.6{\pm}12.8$세, 평균신장 $154.3{\pm}5.7cm$)의 자료를 분석하였다. 결 과 : 우리나라 성인여성의 AS/Ht ratio는 $1.004{\pm}0.023$이다. 다중선형회귀분석상 양팔벌린 손끝길이와 연령이 모두 신장과 유의한 선형적 관련성을 보였다. Height(cm)=0.7094 Arm span(cm)-0.0891 Age(yr)+48.54(p=0.0001, $r^2$=0.76) AS/Ht ratio를 통한 신장 예측값와 실측값의 차이 즉, 잔차(residual)는 양팔벌린 손끝길이와 연령에 의해서 유의한 영향을 받는다 (p=0.0001). 양팔벌린 손끝길이 또는 연령이 감소할수록 AS/Ht ratio에 의한 신장 예측값은 실측값보다 낮아지며, 양팔벌린 손끝길이 또는 연령이 증가할수록 AS/Ht ratio에 의한 신장 예측값은 실측값보다 높아진다. 회귀방정식을 통한 신장 예측값과 실측값의 차이는 양팔벌린 손끝길이와 연령에 의한 영향을 받지 않는다(p>0.05). 결 론 : 우리나라 성인여성에서 정상폐활량 추정을 위한 신장 예측치를 구하고자 할 때 양팔벌린 손끝길이와 연령의 두 변수를 이용한 회귀방정식을 이용하는 것이 고정된 AS/Ht ratio를 이용하는 것보다 더 정확하다. As/Ht ratio는 양팔벌린 손끝길이와 연령의 양 극단에서 신장을 정확하게 예측하지 못한다.

  • 대구시내 중고등학교에 재학중인 12세에서 17세 사이의 남학생 360명을 대상으로 체격을 측정하여 체격의 대표치라고 할 수 있는 신장을 독립변수로 하고 년령 증가에 따라 변화가 뚜렷한 11가지의 체격치 (체중, 흉위, 좌고, 하지장, 대퇴장, 대퇴위, 하퇴장, 상지장, 상박장, 전박위 및 피부두겹두께)를 각각 종속변수로 하여 회귀분석을 하고 결정 계수를 산출 하였다. 회귀분석의 결과를 보면 회귀계수는 신장에 대한 체중의 회귀계수가 0.90으로 가장컸으며 피부 두겹 두께의 회귀계수가 0.09로서 가장 작았다. 대개 측정치가 크면 회귀계수도 컸으나 그 관계가 꼭 일정하지는 않았다. 직선이나 곡선의 회귀관계에서 두 변량의 관계 표현의 적합도를 나타내는 결정계수는 대퇴장과 피부 두겹 두께의 경우를 제외하면 거의 모두 1에 가까워서 이들은 직선의 회귀방정식으로서도 두 체격치사이의 관계를 무리없이 표현할수 있었으며 특히 피부두겹두께의 경우에는 측정과정에서 일어나는 오차가 전체에 미치는 영향이 상당히 커서 일차회귀로서는 표현이 아무래도 미흡함을 알수 있었다.

  • Objective : Thoracic pedicles have special and specific properties. In particular, upper thoracic pedicles are positioned in craniocaudal plane. Therefore, manipulation of thoracic pedicle screws on the left side is difficult for right-handed surgeons. We recommend a new position to insert thoracic pedicle screw that will be much comfortable for spine surgeons. Methods : We retrospectively reviewed 33 patients who underwent upper thoracic pedicle screw instrumentation. In 15 patients, a total of 110 thoracic pedicle screws were inserted to the upper thoracic spine (T1-6) with classical position (anesthesiologist and monitor were placed near to patient's head. Surgeons were standing classically near to patient's body while patients were lying in prone position). In 18 patients, a total of 88 thoracic pedicle screws were inserted to the upper thoracic spine with the new standing position-surgeons stand by the head of the patient and the anesthesia monitor laterally and under patient's belt level. All the operations performed by the same senior spine surgeons with the help of C-arm. Postoperative computed tomography scans were obtained to assess the screw placement. The screw malposition and pedicle wall violations were divided and evaluated separately. Cortical penetration were measured and graded at either : 1-2 mm penetration, 2-4 mm penetration and >4 mm penetration. Results : Total 198 screws were inserted with two different standing positions. Of 198 screws 110 were in the classical positioning group and 88 were in the new positioning group. Incorrect screw placement was found in 33 screws (16.6%). The difference between total screw malposition by both standing positions were found to be statistically significant (p=0.011). The difference between total pedicle wall violations by both standing positions were found to be statistically significant (p=0.003). Conclusion : Right-handedness is a problem during the upper thoracic pedicle screw placement on the left side. Changing the surgeon's position standing near to patient's head could provide a much comfortable position to orient the craniocaudal plane of the thoracic pedicles.

  • This study developed a functional dress shirt for adult males that reflected the body surface variation of a human body section by motion. This study conducted a 3D body scan for 8 subjects in their 40's based on the Size Korea 2010 database. Data recorded the proper posture change value and body surface change value to develop functional dress shirts for adult males. We scanned the subjects with a 3D body scanner for five primarily male wearing dress shirts and operating postures, right standing, arms raised to $90^{\circ}$ horizontal forward position, arms raised $90^{\circ}$ to the horizontal position side, lift up the arm $180^{\circ}$, and arm forward $90^{\circ}$ in a bent posture. We analyzed the 3D scan data from those motions to examine change of length using 3D software Rapidform XOS. The results indicated that the body surface sections with contraction were the front and rear shoulder area, armpit and central length as well the width of arms at more than 10%. The increased body section included the body and armpit back length; in addition, the rear arm vibration girth and under arm girth were more than 10%. In order to reflect the size variation of for each motion, the ease amount of the front and rear shoulder length and width needs to be reduced 20% because it affects the shoulder length during the right standing. The results suggest that the ease amount of the shoulder length should be minimal. The ease amount of the back size needs to be 0.5-2cm bigger and set 0.5-1.5cm longer than the dress shirt length side drooping to compensate for the side length shortage of each motion. The sleeve length needs to be 0-0.5cm shorter, and ease amount of the girth of sleeve bottom needs to be reduced 0-0.7cm due to the size variation of arms. However, the girth of the rear arms is suggested to be 0-0.6cm longer in the ease amount to the rear arm girth as the extension is more than 10% over the width and length of each motion.

  • Background : This study verified a correlation between gross motor performance measure (GMPM) and pediatric balance scale (PBS) for children, which are most widely used for assessment of children with cerebral palsy. Methods : The study subjects are 20 children aged between five and 13 who were diagnosed with cerebral palsy. Their mean age was $8.15{\pm}2.96years$ and consists of 15 males and 5 females. The subjects were divided into three groups according to muscle tone and motility disorders and then GMPM and PBS were assessed. In the assessment items in the GMPM, alignment, coordination, dissociated movement, stability, and weight shift were measured. The PBS consists of sitting to standing, standing to sitting, moving between chairs, standing without using hands, standing with one foot, turning 360 degrees, turning to look behind, retrieving object from floor, and reaching forward with outstretched arm while standing. A correlation of the collected data was analyzed using SPSS 18.0 for windows. Results : From Significant correlations were shown between items of GMPM and PBS as well as total scores of GMPM and PBS. Among them, coordination and weight transfer in the GMPM items had a high correlation with the PBS. In addition, the higher the GMPM total score was, the higher the PBS score was. Conclusion : This study result showed a significant correlation between GMPM and PBS, and this relation can be used to pediatric physical examination.
