The purposes of this study were to investigate the difference of the SCM activities in the general characteristics of fashion enterprises and to inquire out the general characteristics affecting the introduction of SCM. The characteristics of apparel manufactures were also compared through the cluster analysis of the SCM activity levels of apparel manufactures. Through questionnaire survey, a total af 214 data - 123 from 64 apparel manufacturers, 46 from 40 fabric suppliers and 45 from 4 retailers - were used for analysis. The analysis on the relation between the SCM activity levels and the general characteristics of fashion enterprises showed that the SCM activities were affected by product assortment pattern and SCM introduction level for fabric suppliers, production method, product assortment pattern, business type and SCM introduction level for apparel manufacturers, and SCM introduction level for retailers. The cluster characteristics related to the SCM activity levels of apparel manufacturers showed that the clusters with higher level were tending to doing business internationally and trying to manufacture in a small lot in variety. The higher level clusters also revealed relatively low in the occupation ratio of fashion goods and high in quick response ratio compared to the lower level clusters.

This study is intended to look into the structural relationship between SCM activity, process innovation and quality performance in small and medium sized enterprisers(SMEs). To achieve this, a survey was empirically carried out to 354 SCM operating officers and managers who perform the SCM activities in small and medium sized manufacturing firms. The results are summarized as follows. Overall, the SCM activity and process innovation had a significant effect on the quality performance, having a structural relationship with the quality performance in SEMs. This implies that the strategic alliance of the SCM activities and competence concentration based on technology development in SEMs can organize the unity through organizational members' information sharing. In other words, when the information integration supports the compatibility and reliability of shared information system by raising technological competence through this, the process innovation can lead to non-financial cost reduction, product quality, delivery compliance and inventory cost reduction as quality performance of the structured process, management and distribution.

The purpose of this study was to evaluate the level of SCM activities and the logistics performance by SCM of the three company types in fashion industry· fabric suppliers, apparel manufacturers, and retailers. The level of SCM activities was estimated through the examination of seven factors: commitment and leadership of a top management, flexibility of management, understanding of demand characteristics, integrated management organization, information system, cooperative partnership and communication and exchange of opinion. The logistics performance was measured by improvement in customer service(on time delivery ratio of products, returning rate, treat ratio for A/S, order fill rate, substitute providing capability for being out of stock) and delivery cost reduction. Through questionnaire survey, a total of 214 data for 108 companies of three company types were collected: 46 for 40 fabric suppliers, 123 for 64 apparel manufacturers and 45 for 4 retailers. The analysis of SCM activity levels showed that fabric suppliers had higher degrees in the factor of understanding of demand characteristics, and apparel manufacturers had higher degrees in the factor of information systems. For retailers, the factor of communication and exchange of opinion represented higher degrees. The study on relationship between the SCM activity levels and logistics performance showed that the SCM activity factor of understanding of demand characteristics greatly improved a substitute providing capability for being out of stock in fabric suppliers, and information system improved a substitute providing capability for being out of stock, on time delivery ratio of products and order fill rate in apparel manufacturers. In retailers, the SCM activity factor of understanding of demand characteristics decreased returning rate highly and improved on time delivery ratio of products. The study results showed that SCM activities in fashion industry brought more improvement in customer service levels rather than in delivery cost reduction.

Abdominal curl-up exercise may excessively increased superficial neck flexor such as sternocleidomastoid (SCM) muscle. Also, the muscle activity of the abdominal muscles haven't investigated during abdominal curl-up with craniocervical flexion (CCF). Therefore, the purpose of our study was to determine the effect of CCF on the muscle activity of the abdominal and SCM muscles during abdominal curl-up. Twelve healthy subjects (six men and six women) with no history of abdominal or lower back pain within 6 weeks were recruited. Surface electromyographic signals were collected on SCM, rectus abdominis (RA), internal oblique (IO), and external oblique (EO) muscles bilaterally during performing the traditional abdominal curl-up and the abdominal curl-up with CCF. Paired t-tests were used to compare the differences in the muscle activity of the bilateral SCM, RA, EO, and IO muscles between the traditional abdominal curl-up and the abdominal curl-up with CCF (p<.05). There was significantly lower electromyogram (EMG) activity of the both SCMs during the abdominal curl-up with CCF (Right SCM, $39.50{\pm}15.29%MVIC$; Left SCM, $38.24{\pm}17.31%MVIC$) than with the traditional abdominal curl-up (Right SCM, $54.85{\pm}20.05%MVIC$; Left SCM, $53.18{\pm}26.72%MVIC$) (p<.05). The activity of abdominal muscles were not significantly different between the traditional abdominal curl-up and the abdominal curl-up with CCF. The abdominal curl-up with CCF requires significantly less muscle activity of SCM. Consequently, the abdominal curl-up with CCF is recommended to prevent excessive activation of superficial cervical flexors during abdominal curl-up exercise.

PURPOSE: This study was to investigate the effect of applying neck flexion during elbow flexion exercise on muscle activity of the biceps brachii, the anterior deltoid and the sternocleidomastoid (SCM). METHODS: Twenty healthy adults participated in this study. The subjects measured %MVIC (Maximal volumetric control) and collected the maximum electromyography (EMG) values in the biceps brachii, anterior deltoid, SCM. The first action was to sit in a sitting position with the eyes facing front and maintained the weight of each section by performing elbow flexion using a tension gauge. The second action was to sit in a sitting position with the head down and maintained the weight of each section by performing elbow flexion using a tension gauge. Paired T-test was used for comparison of the before-and-after neck flexion to analyze the muscle activity of the Biceps brachii of next flexion and extension, the SCM, and the Anterior deltoid during elbow flexion exercise. The Repeated measured ANOVA was used for comparing %MVIC in each muscle. The significance level (?) was set at .05. RESULTS: Neck flexion during elbow flexion increased the muscle activity of the Biceps brachii and Anterior Deltoid muscle in the maximal muscle strength 50 ~ 60%, 70 ~ 80% and decreased the muscle activity of the SCM (p < .05). CONCLUSION: The applic has been confirmed to reduce the mobilization of the SCM and increase the mobilization of the Biceps brachii and Anterior Deltoid to increase the mobilization. Therefore, it seems effective to apply neck flexion when elbow flexion exercise.

This study first conceptualizes and investigates five dimensions of SCM activities, such as organizational capacity, revitalization support collaboration, appraisal and responsibility, and information system activities. Second, this study develops three dimensions of a supply chain structure, and proposes a balanced scorecard (BSC) model in order to measure business performance. And then, this study establishes too research hypotheses as follows: H1. The SCM activities varies with the supply chain structure. H2. The management performance varies with the supply chain structure. In the questionnaire survey for empirical analysis, this study carefully selected 809 of companies in Korea. We conducted a survey by mail and collected 127 data. Out of 127 data we actually used 103 responses for statistical analysis. After conducting statistical analysis, we could find the results as followed: 1) The supply chain structure was classified into three networks through a clustering procedure, such as supply network, conversion network, and distribution network, and these networks were used to testify hypotheses. As a result the effect of SCM activities varies according to three networks and especially, the companies in distribution network were more active than those in supply and conversion networks doing SCM activities. 2) We may conclude that business performance varies with three networks, and distribution network achieves better performance than supply and conversion networks do.

Background: The craniocervical flexion (CCF) exercise is one of the effective exercise in correcting forward head posture (FHP). However, some people with FHP achieve CCF with compensatory movements, for example, low cervical flexion using superficial neck flexors such as the sternocleidomastoid (SCM) muscle. No study has yet investigated whether a dual­pres ure biofeedback unit (D-PBU) method to prevent low cervical flexion would be helpful in performing pure CCF movement. Objects: The purpose of this study was to compare the effects of the CCF using D-PBU method and the traditional CCF method on the cross-sectional area (CSA) of the longus colli muscle (LCM) and the activity of SCM muscle in subjects with FHP. Methods: Twenty­four FHP subjects (male: 16, female: 8) were recruited for this study. All subjects performed CCF using two different methods: the traditional CCF method and the CCF using D-PBU method. The CSA of the LCM was measured via ultrasound, and surface electromyography was used to measure SCM muscle activity. Results: The change in CSA of the LCM was significantly larger during the CCF using D-PBU method ($1.28{\pm}.09$) compared with the traditional CCF method ($1.19{\pm}.08$) (p<.05). The SCM muscle activity using the CCF using D-PBU method ($2.01{\pm}1.97$ %MVIC) was significantly lower than when using the traditional CCF method ($2.79{\pm}2.32$ %MVIC) (p<.05). Conclusion: The CCF using D-PBU method can be recommended for increasing LCM activation and decreasing SCM muscle activity during CCF movement in subjects with FHP.
