오늘날 가계소득의 향상과 근로시간 단축으로 인해 삶의 질이 향상되어감에 따라 보다 풍요롭고 여유있는 생활문화로의 변화가 예상되고 있다. 반면 생활이 윤택해지면서 영양섭취 과다와 노동여건의 변화(육체적 노동$\rightarrow$정신적 노동)로 인해 비만과 운동부족을 야기하여 많은 신체적 부작용을 유발시키고 있다. 이로 인해 오늘날 대다수 국민의 관심은 건강에 집중되고 있으며 운동에 대한 인식이 날로 증대되고 있다. 이러한 현상은 매년 20%이상의 높은 헬스기구 시장의 성장률로 대변된다. 최근 주목받고 있는 Elliptical Cross Trainer(이하, ECT) 스키의 상체운동과 달리기의 하체운동을 결합한 논임팩트 운동기구로써, 토탈 전신 유산소 운동을목적으로 개발된 크로스 트레이닝 운동기구이다. 이미 유럽과 미주 등의 해외 시장에서 트레드밀과 대등한 시장을 형성하고 있고 근래 한국을 비롯한 동북아시아 시장에서 그 성장이 급격히 확대되고 있다. 이러한 수요확대에도 불구하고 대부분의 고가 ECT는 몇몇 선진국이 독점하고 있어 한국기업의 시장 경쟁력 제고와 시장 확대 측면에서 ECT의 국산화는 시급히 요구되고 있다. ECT 디자인 개발은 세계 일류 상품만이 시장경쟁력을 가질 수 있다는 배경아래 디자인을 전략적으로 특화하여 사용자 관찰과 인간공학에 입각한 사용자 중심 디자인, 첨단 공학기술과 디자인 융합을 중점적으로 실행하였다. 이를 위해 참여 디자이너들은 개념설계, 기본설계, 상세설계에 이르는 전 과정에서 엔지니어들과 협력하며 연구하였다. 본 논문은 ECT개발을 위한 디자인과 공학의 협업적 연구개발과정과 결과를 소개하였다.$-37.83%{\sim}44.36%$로 큰 차이를 보였다._d)$의 비$(L_d/D)$에 따른 전면교각에서의 수류변화의 영향이 후면교각에 작용하여 상호 복합적인 흐름 및 세굴특성을 나타내므로 이와 같은 복렬형 원주군의 세굴특성을 파상형 원주교각에 적용하여 국부세굴의 크기 변화를 해석하였다. 따라서, 교각주위에서의 수류특성 및 세굴의 변동은 원주군 및 교각파상의 크기와 간격 등과 같은 구조물의 배열조건과 Froude 수, 수심 등의 수리학적 조건에 따라 달라지므로 이의 조건을 체계적으로 변화시켜 가면서 교각주위에서의 국부세굴 및 세굴 감소특성을 검토하였다. 실험결과 오목 및 볼록 파상형 원주 주위에서의 세굴크기는 원형원주와 비교하여 전체적으로 감소하는 것으로 확인되었으며 특히 오목형 $B/\acute{h}=3$에서는 세굴경감효과가 탁월하여 70%이상 감소하는 것으로 확인되었으나 볼록형 $B/\acute{h}=5$에서는 세굴촉진특성이 나타나고 있는 것으로 나타났다. 따라서, 파상형 원주에서는 하강류나 와류를 파상형의 내부로 유도하여 세굴의 크기를 조절할 수 있는 최적의 파상이 존재하고 있는 것으로 예측되었다.원 분야 소프트웨어의 개발에 기본 토대를 제공할 것으로 판단된다.았다. 또한 저자들의 임상병리학적 연구결과가 다른 문헌에서 보고된 소아 신증후군의 연구결과와 큰 차이를 보이지 않음을 알 수 있었다. 자극에 차이가 있지 않나 추측되며 이에 관한 추후 연구가 요망된다. 총대장통과시간의 단축은 결장 분절 모두에서 줄어들어 나타났으나 좌측결장 통과시간의 감소 및 이로 인한

본 연구는 8주간의 고강도 동계 훈련 시 L-아르기닌 섭취가 남자 대학 태권도 겨루기 선수의 경기수행능력, 젖산, 젖산탈수소효소 및 암모니아에 미치는 영향을 구명하기 위해 L-아르기닌 섭취군(n=14), 위약군(n=14)으로 구분하여 실시하였다. L-아르기닌 섭취군은 일일 아침 1 g, 점심 1 g, 저녁 1 g으로 총 3 g 섭취하였고 위약군은 말토덱스트린을 동일한 방법으로 섭취하였다. 8주간의 동계 훈련 프로그램은 70-90%HRR로 실시하였다. 측정된 자료의 L-아르기닌 섭취군과 위약군 간의 그룹 및 시기 간 상호작용 효과는 two-way repeated measures ANOVA, 그룹 내 시기 간 차이는 paired t-test를 사용하였으며, 그룹 간 차이는 independent t-test를 사용하여 분석하였다. 그 결과 TAAA (Taekwondo-specific aerobic anaerobic agility) test를 통한 경기수행능력 중 평균 발차기 수에서 그룹×시기 간 상호작용 효과가 나타났으며 그룹 간 주효과가 나타났다(p<.05). 또한, 발차기 피로지수에서 그룹×시기 간 상호작용 효과가 나타났다(p<.05). 한편, 젖산에서는 시기 간 주효과가 나타났으며(p<.05) 젖산탈수소효소에서 상호작용 효과 및 시기 간 주효과 나타났다(p<.05). 암모니아의 경우 그룹×시기 간 상호작용 효과가 나타났다(p<.05). 이러한 결과는 남자 대학 태권도 겨루기 선수의 고강도 훈련 후 피로에 쉽게 노출되는 선수들에게 L-아르기닌 섭취로 인해 체내 피로 유발 물질들을 신속하게 제거하는 데 긍정적인 역할을 할 수 있다고 사료된다. 따라서 고강도 엘리트 태권도 겨루기 운동선수의 경기수행능력 향상과 피로 회복 방법으로 L-아르기닌 섭취를 권장한다.

Purpose: Sinus tarsi syndrome (STS) is caused by various pathologies. However, the exact etiology of STS remains controversial. This study evaluated the imaging and arthroscopic findings of patients who underwent surgical treatment after conservative treatment for STS failed. Materials and Methods: Between December 2014 and August 2018, 20 patients (21 cases) who underwent surgical treatment for STS were included in the study. The clinical results were analyzed using the visual analog scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot functional scale. The radiographic results were analyzed using Meary's angle, calcaneal pitch angle, and hindfoot alignment angle. The pathologic conditions of sinus tarsi were confirmed by magnetic resonance imaging (MRI) and subtalar arthroscopy. Synovitis, bone edema, and accessory anterolateral talar facet (AALTF) were evaluated on MRI. Synovial thickening, cartilage damage, interosseous talocalcaneal ligament (ITCL) and cervical ligament rupture, soft tissue impingement, AALTF, and accessory talar facet impingement (ATFI) were evaluated by subtalar arthroscopy. Results: The mean duration of symptoms was 28.7 months (4~120). All patients showed significant improvement in the VAS and AOFAS ankle-hindfoot scale. Significant improvements in hindfoot alignment angle and Meary's angle postoperatively were noted in patients who underwent medial displacement calcaneal osteotomy. MRI confirmed synovitis in all patients, AALTF in 19 cases (90.5%), and ATFI with bone edema in seven cases (33.3%). In subtalar arthroscopy, pathologic conditions were observed in the following order: synovitis in 21 cases (100%), AALTF in 20 cases (95.2%), ITCL partial rupture in nine cases (42.9%), and soft tissue impingement in seven cases (33.3%). All cases had two or more pathological conditions, and 15 (71.4%) had three or more. Conclusion: In cases of STS that do not respond to conservative treatment, a comprehensive examination of the lesions of the tarsal sinus and lesions around the subtalar joint is essential.

Objective: The purpose of this study was to measure the morphological characteristics of the foot and biomechanical variables of the lower extremity joints during vertical jump and investigate the relationship between foot morphology and biomechanics of vertical jump. Method: 24 men in their 20s (age: 22.42 ± 1.41 yrs, height: 173.37 ± 4.61 cm, weight: 72.02 ± 6.21 kg, foot length: 251.70 ± 8.68 mm) participated in the study. Morphological characteristics of the foot included the length of the first toe, the length of the second toe, and the horizontal length from the center of ankle joint to the achilles tendon (Plantar Flexion Moment Arm [PFMA]). Biomechanical variables were measured for plantar flexor strength of the ankle joint and peak angular velocity, moment, and power of the lower extremity joint during vertical jump. Results: There was a significant correlation between the length of the first toe and plantar flexion strength at 30°/s [r=.440, p=.016], the angular velocity of the metatarsophalangeal [MTP] joint [r=-.369, p=.038] while significant correlations between PFMA and the angular velocities of the knee joint [r=.369, p=.038] and ankle joint [r=.420, p=.021] were found. There were also significant correlations between the length of the first toe and the maximum moment of the hip joint [r=.379, p=.034], and the length of the second toe and the power of the hip joint [r=-.391, p=.029]. Finally, significant correlations between PFMA and the power of the ankle joint [r=.424, p=.019] and MTP joint [r=.367, p=.039] were found. Conclusion: Based on the results of this study, the length of the toe and PFMA would be related to the function of the lower extremity joint. Therefore, this should be considered when designing the functional structure of a shoe. Furthermore, this relationship can be applied to intensive training for the plantar flexors and toe flexors to improve power in athletic performance.
