        The purpose of this study was to assess the influence of two shoe size conditions on foot pressure, ground reaction force (GRF), and lower extremity muscle fatigue. Seven healthy men participated. They randomly performed walking and running in two different conditions: proper shoe size and 10 mm greater than proper shoe size. Peak foot pressure, and vertical, anterior and mediolateral force components were recorded with the Parotec system and Kisler force platform. To assess fatigue, the participants performed treadmill running for twenty-five minutes twice, each time wearing a different shoe size. Surface electromyography was used to confirm localized muscle fatigue using power spectral analysis of four muscles (tibialis anterior, gastrocnemius medialis, rectus femoris, and biceps femoris). The results were as follows: 1) In walking conditions, there was a significantly higher peak pressure in the 10 mm greater than proper shoe size insole sensor 1, 2, 14, and 18 (p<.05). 2) In running conditions, there was a significantly higher peak pressure in the 10 mm greater than proper shoe size insole sensor 5, 14, and 15 (p<.05). 3) In walking conditions, there was a significantly higher first maximal vertical GRF in the 10 mm greater than proper shoe size (p<.05). 4) In running conditions, no GRF components were significantly different between each shoe size condition (p>.05). 5) Muscle fatigue indexes of the tibialis anterior and rectus femoris were significantly increased in the 10 mm greater than proper shoe size condition. These results indicate that wearing shoes that are too large could further exacerbate the problems of increased foot pressure, vertical GRF, and muscle fatigue.

        The purpose of this study was to determine the effect of lift to the shoe of the affected limb on gait patterns in subjects with hemiplegia. The subjects of this study were 18 post-stroke hemiplegics. For the study, insole of the paretic side was lifted 10mm higher, and duration of static weight bearing, dynamic weight bearing and stance phase were measured from one cycle of the gait, before and after the lift application. For the measurement of carry-over effect of lift, we got data of those three items prior to and 3 weeks after lift application and 3 days after removal of the lift. Static weight bearing was significantly increased both just after and continuous application of lift for 3 weeks than before. Dynamic weight bearing was significantly decreased in heel contact and footflat phases only when just after application of the lift, without any change after 3 weeks application. In heel-off phase, dynamic weight bearing did not show any significant difference between before and just after application of lift whereas significantly decreased after 3 weeks application. Duration of stance phase was not changed among anytime of application. According to this study, lift applied to the shoe of the peretic limb was effective in inducing static weight bearing in the paretic limb, but did not significantly effect dynamic weight bearing on gait patterns. This study suggests that symmetry, induced by shoe lift applied to the paretic limb, could help correct abnormal posture that would be caused in standing and prevent development of abnormal muscle tone in subjects with hemiplegia caused by unilateral stroke.

        This study was conducted to identify the effects of high-heel shoes on EMG activities of rectus femoris and biceps femoris in 28 healthy women. Subjects were composed of experimental group (wearing high-heel shoes) and control group (wearing low-heel shoes). Two groups participated in three conditions standing (bare foot wearing athletic shoes and 7.5 cm height shoes). In high-heel shoes condition, EMG activities of rectus femoris of control group were significantly lower than that of biceps femoris of experimental group, but EMG activities of both muscles of experimental group did not should significant difference. In bare foot standing condition, EMG activities of rectus femoris of experimental group were significantly lower than that of biceps femoris but EMG activities of both muscles of control group had no significant difference. These results showed that hamstring lengthening effects was produced when wearing high-heel shoes because the external knee extension moment was increased. In the short term, high-heel shoes effect on the increase of the biceps femoris activities by spindle reflex, but in the long term, the normal amplitude of the same muscle activities by Golgi tendon organ reflex.

        The purpose of this study were to compare light touch, two-point discrimination, position sense, and static balance ability and to examine the relationship of static balance ability and different senses in those who are wearing various heights of high-heeled shoes. Each 29 women was classified two different heights (below 3 cm, above 7 cm) by experience in wearing shoes. A t-test was used to determine the differences between low- and high-heeled shoe in light touch, two-point discrimination, position sense, and static balance ability. Pearson correlation was used to examine the relationship of static balance ability to these sensation. The results were as follows: 1) No significant differences in average light touch, position sense between two groups were found(p>0.05). But significant differences in average two-point discrimination, static balance ability were found(p<0.05). 2) Static balance ability was not significantly correlated with light touch, position sense, two-point discrimination(p>0.05). The results suggest that long time experience in wearing high-heeled shoe may be caused local sensory change and decreased static balance ability. Even though, static balance ability was not significantly affected but correlated with two-point discrimination, position sense, and light touch in order.

        본 연구는 임금 상승 등 立地優位 요인의 상실에 따른 전반적인 한국 신발산업의 경쟁우위의 약화에도 불구하고 輸出成果가 신장되는 기업들의 성과 決定要因을 戰略經營을 중심으로 하는 기업 內部能力에 시각을 맞추어 규명하고자 하는 데 목적이 있다. 한국의 신발기업들은 4가지 전략군으로 구분되었는 바 이러한 전략군에 따라 成果와 기업 내부능력에 있어서 差異를 보여주고 있으며 技術 差別化 전략은 기업성과와 경영전략의 仲裁變數 역할을 하지 않는 것으로 나타나고 있다. 환경-전략 적합과 기술전략-경영전략의 적합은 성과에 有意한 영향을 미치지 않으나 전략-집중 적합은 성과에 유의한 영향을 미치는 것으로 나타났다. 기업내부우위 요인이 성과에 미치는 영향이 상대적으로 크게 나타나 기업차원에서의 競爭力 提高를 위 한 능동적이고 적극적인 노력은 열악해지는 외부환경에서도 보상을 받음을 示唆하고 있다. 나아가 분석 결과의 戰略的 含意가 결론적으로 다루어지고 있다.

        본 연구의 목표는 신발 굽 높이에 따른 Kager씨 삼각 면적의 방사선영상 변화와 후종족부의 표면온도 변화를 알아보고자 연구하였다. 카이거씨 면적은 단순 방사선촬영검사와 인피니티 영상저장전송시스템을 이용하여 측정 하였다.후종족부의 표면온도는 전산화적외선체열검사를 이용하여 측정하였다. 운동화 착용 대상자에게 신발 굽 높이가 다른하이힐을 착용시켜 카이거씨 삼각 면적과 후종족부의 표면온도 차이를 분석 하였다. 하이힐 대상자들은 운동화 대상자들에 비하여 카이거씨 삼각 면적이 0.88cm², 후종족부의 표면온도가 1.4℃ 각각 감소하였다. 최고신장과 최저신장의 카이거씨 면적과 표면온도의 차이는 운동화와 하이힐에서 각각 0.9cm²,1.2cm²,1.6℃,0.5℃이며 모두 미세한 차이를 나타냈다. 최고체중과 최저체중의 카이거씨 면적과 표면온도의 차이는 운동화와 하이힐에서 각각 1.8cm²,0.8cm²,1.1℃,0.2℃이며 체중이 높을수록 카이거씨 면적과 표면온도가 감소하였다. 하이힐 최장시간 착용자와 최저시간 착용자의 카이거씨 면적과 표면온도의 차이는 각각 0.8cm², 1.4℃, 이며 착용시간이 증가함에 따라 카이거씨 면적과 표면온도가 감소하였다. 결론적으로 하이힐을 장시간 착용하면 후종족부 통증과 혈류 장애를 유발 할 것으로 고려된다.

        The health symptoms assessment and urinary hippuric acid excretions of workers exposed to toluene occupationally in shoes workshops were investigated by the questionnaire and the field monitoring. Based on the results, the acute health symptoms of workers exposed to toluene by questionnaire were fatigue(58.7%), irritation of the eyes, nose and throat(57.2%), and skin dryness(43.3%). And the complaints about workshop environment are odor, dust and noise. The mean values of urinary hippuric acid excretions in male and female were 1.08 ± 0.50 g/ℓ, 1.59 ± 1.27 g/ℓ in total workers, espectively.
