운동화 안감으로 사용되는 부드러운 천연 가죽의 내부 구조 및 쾌적성과 유사하게 개발한 3종류의 편성포에 관하여 수분 전달 능력을 비교 측정하였다. 편성포 표면에 이면으로 땀액의 이동성을 측정하기 위하여 새로운 실험 절차를 고안하여 측정한 결과, 편성포에 가한 압력은 수분 이동 능력에 영향을 미치지 않았다. 그러나 편성포의 기모가 있는 표면과 기모가 없는 이면의 수분 이동 능력이 달랐고, 3종류중 한 편성포에서는 표면의 기모는 수분전달을 저하시켰다. 표면은 기모, 이면은 평편조직으로 두껍고 무거운 편성포의 수분전달이 가장 좋았고 이 편성포와 같은 조직이면서 두께와 중량이 적은 편성포는 수분전달이 감소되었다. 수분이동 능력을 향상시키기 위하여 편성포의 섬유와 구조를 고려할 때 기모량은 중간 정도이고 기모된 표면을 수분에 접하도록 하는 것이 바람직하다. 이렇게 함으로서 더 효과적인 수분 이동이 이루어져서 피부 표면에서 땀증발이 좋았다. 이 연구에 사용된 실험 방법은 편성포의 수분 이동 체계에 관한 이해 증진에 기여할 수 있다고 본다.

This study was performed to investigate the kinematic and kinetic differences between functional walking shoe(FWS) and general sports shoe(GSS). The subjects for this study were 4 male adults who had the walking pattern of rearfoot strike with normal feet. The movement of one lower leg was measured using force platform and 3 video cameras while the subjects walked at the velocity of 2/1.5 m/s. The findings of this study were as follows 1. The angle of lower leg-ground and angle of knee with FWS was greater than with GSS at the moment of strike the floor and the moment of second peak ground reaction force. The decreasing rate of angle of ankle was smaller in FWS from the strike phase to the second peak ground reaction force. These mean upright walking and round walking along the shoe surface. 2. The maximal Increased angle of Achilles tendon and the minimal decreased angle of rearfoot were smaller in FWS very significantly(p<0.001). Thus FWS prevent the excessive pronation of ankle and have good of rear-foot control. 3. The vortical ground reaction force and the rate of it to the BW were smaller in FWS statistically(p<0.001). The loading rate was smaller in FWS, too, and thess represent the reduction of load on ankle joint and prevention of injuries on it.

Mass Customization combines the advantages of mass production and customization. Mass customization has been praised as an innovative approach that would result in changes in business paradigm. However, there is no consensus on the concept of mass customization, but only a generally accepted framework exists to explain successful practices. Prior cases in mass customization are those of the small-medium sized or Internet-based companies. We in this paper explore the mass customization cases of market-leading manufacturers. Although those traditional organizations may be not for swift change, the cases of those companies are important because they target mass markets. Lampel and Mintzberg[35] proposed a continuum of strategies ranging from pure standardization to pure customization. This study investigates mass customization strategies of three companies. In this paper, the cases of cosmetics and sports shoe can be described as tailored customization, and the household appliances case can be classified as customized standardization. These three cases are compared with each other from the customers' decoupling point. Findings and implications of this research are discussed.

본 연구에서는 브랜드 개성이 제품의 개성을 판단하는데 영향을 미치는가에 대하여 설문을 통해 살펴보았다. 동일한 제품에 대하여 개성이 상이한 브랜드가 적용되었을 경우 제품의 개성을 판단함에 있어 브랜드 개성의 특성이 반영되는지 여부를 확인하고자 하였다. 설문을 위하여 두 켤레의 신발을 준비하였으며 각각은 상징적인 측면이 강조된 여성용 하이힐 제품과 기능적인 측면이 강조된 운동화로 구성하였다. 각 제품에 대하여 명품브랜드(Versace), 일반 상용 브랜드(독일: C&A, 한국: 밀리오레), 그리고 브랜드가 부착되지 않은 총 6장의 사진을 준비하였다. 실험에 앞서 별도의 피험자들이 상기 사용된 브랜드들에 대하여 "frohlich/유쾌함(cheerful)", "ehrlich/정직함(honest)", "provokativ/도발적인(provocative)"의 형용사로 평가를 하였다. 본 실험에서는 실험참여자에게 각 신발들의 3가지 사진 중 무작위로 선정된 사진을 한 장씩 보여주고, 각각에 대해 브랜드 측정에 사용했던 동일한 평가항목을 이용하여 평가하도록 했다. 더불어, 본 연구는 개인주의 문화권에 비하여 집단주의 문화권에서 브랜드의 영향이 더 두드러지게 나타나는 지를 알아보기 위하여 독일의 만하임대학(Universitaet Mannheim)과 한국의 한국과학기술원(KAIST) 학생들을 위주로 설문을 실시하여 문화적 차이에 따른 브랜드 영향력을 비교하고자 하였다. 실험결과에서는 독일과 한국 모두에서 브랜드 개성이 제품 개성에 유의한 영향을 미치지 않는 것으로 나타났으나, 브랜드 개성이 제품의 기능적 측면(가격)에는 영향을 미치는 것으로 나타났다(p<.001).

The purpose of this study was to find the relationship between Achilles tendon angle, angular velocity from 2D cinematography utilized to easily analyze the functions of shoes, ankle joint moment, knee joint moment, and hip joint moment from 3D cinematography utilized to predict the injury. Also, this study was to provide the optimal standard to analyze the injury related to the shoes. Subjects in this study were 30 university male students and 18 conditions (2 types of running speed, 3 of midsole hardness, 3 of midsole height) were measured using cinematography and force platform. The results were as following. 1) Hip joint abduction moment was effected by many variables such as running speed, midsole height, maximum achilles tendon angle, ground reaction force. 2) Knee joint rotational moment in running was approximately 1/10 - 1/4 times of the injury critical value and eversion moment was approximately 1/4 - 1/2 times of the injury critical value. 3) Ankle joint pronation moment in running was 1/3 - 1/2 times of the injury critical value. 4) Knee joint rotational moment was found to be irrelevant with maximum achilles tendon angle or angular velocity. 5) Pronation from running was thought to be relevant to rather eversion moment activity than rotational moment activity of knee joint. 6) Plantar flexion abductor of ankle showed significant relationship with the ground reaction force variable. 7) When the loading rate for ground reaction force in passive region increased, extensor tended to be exposed to the injury. Main variables in biomechanical analysis of shoes were impact absorption and pronation. Among these variables, pronation factor was reported to be relevant with knee injury from long duration exercise. Achilles tendon angle factor was utilized frequently to evaluate this. However, as the results of this study showed, the relationship between these variables and injury relating variable of knee moment was so important. Studies without consideration on this finding should be reconsidered and reconfirmed.

This study was conducted to determine what effects would the midsole hardness of running shoes have on shoe flex angle and maximum propulsive force. Furthermore, the relationship between the shoes flex angle and maximum propulsive force was elucidated in order to provide basic data for developing running shoes to improve sports performances and prevent injuries. The subjects employed in the study were 10 college students majoring in physical education who did not have lower limbs injuries for the last one year and whose running pattern was rearfoot strike pattern of normal foot. The shoes used in this study had 3different hardness, shore A 40(soft), 50(medium) and 60(hard). The subjects were asked to run at a speed of $4{\pm}0.08m/sec$, and their movements were videotaped with 2 S-VHS video-cameras and measured with a force platform. And the following results were obtained after analyzing and comparing the variables. 1. Although the minimum angle of shoes flex angle was estimated to appear at SFA4, it appeared at SFA2 except in those shoes with the hardness of 40. 2. The minimum angle of shoes flex angle was $145.1^{\circ}$ with barefoot. Among the shoes with different hardness, it was the smallest when the hardness was 50 at $149.9^{\circ}$. The time to the minimum angle was 70.7% of the total ground contact time. 3. Maximum propulsive force according to midsole hardness was the largest when the hardness was 50 at $1913.9{\pm}184.3N$. There was a low correlation between maximum propulsive force and shoes flex angle.

This paper introduced a new preparation method of a composite rubber by mixing BR (butadiene rubber) and CIIR (chloro-isobutyl rubber) for the purpose of improving frictional property of BR. Since BR has high abrasion and low frictional properties, its frictional property needs to be enhanced in order to be used as an outsole of a sport shoe. Such enhancement was difficult to achieve by simple blending of CIIR. In here, CIIR was added into BR matrix after CIIR was pre-crosslinked for a time period, and both high frictional and high abrasion resistance properties were achieved. Our experiments showed that the composite rubber blend of 60% of BR and 40% of pre-crosslinked CIIR had desired BR's frictional and abrasion resistance properties for sport shoes.

Purpose : The purpose of this study was to determine the effect of book bag handling styles and types of footwear on muscle activation of erector spine muscles and calf muscles. Methods : Ten participants took off their book bags and used sneakers to walk on a treadmill for 30 minutes. The following day, 10 participants put on their backpack with 10% of the weight and used sneakers to walk on the treadmill for 30 minutes. On the last day, 10 participants put on their backpack with 10% of the weight and used formal shoes to walk on the treadmill for 30 minutes. After walking on the treadmill at 3 mph for thirty minutes, we measured muscle activation in erector spine muscles and calf muscles. Results : The results of this study showed the activation of the erector spine muscles and the calf muscles significantly increased when walking with a book bag and the activation of the erector spine muscles and the calf muscles significantly increased when walking in formal shoes. Conclusion : Using a backpack and formal shoes increase muscle activity of erector spine muscles and calf muscles. The results of this study indicate that not using a backpack and wearing sneakers are more beneficial than that using a backpack weighted 10% and wearing formal shoes and can be recommended to adult women by clinicians.
