In this study, as the result of analyzing the relationship and influence between economic outcome and R&D supporting investment, the number of supporting subjects among the technological innovational areas of SMEs, it is as below. First, as the economic result of analyzing companies from the investment in R&D of technological innovational areas of minor companies, the number of supporting subjects and amount of R&D have relationship with increase of sales and export amount, employee reduction & the effect of new job creation shows positive correlation with the effect of import replacement. Second, as analyzing the influence of the investment in R&D has economic effect from of technological innovational minor companies. This is thought that the financial and R&D support increase a significant effect on economical, technical against SMEs.

Ring Sector Plate Supported by Elastic Beam Although all the reinforced concrete circular ring sector plates are elastically supported, it is conventional to simplify their supporting conditions as fixed or simply-supported ones assuming that their supporting beam has infinite stiffness. However, in order to obtain a precise solution, it should be required to consider the stiffness of their supporting beam. As a methodological improvement to the precise analysis, "Reinforced Concrete Model" previously developed by the author was applied to the structural analysis of the reinforced concrete circular ring sector plates with elastically supported beam. The results of analysis in the cases under various conditions of open angle, steel ratio, relative stiffness(EI/DL) between plate and supporting beam were summarized as follows ; 1.Although the effect of relative stiffness between plate and supporting beam varies depending on the magnitude of open angle, in general, it shows the largest when not more than 5.0 and negligible when not less than 10.0. Therefore, it would be considered as fixed supporting condition :in the case of its open angle of 0$^{\circ}$rectangular plates), its stiffness ratio being not less than 10.0 and in the other case of its open angle of 30$^{\circ}$, its stiffness ratio being not less than 5.0. 2.In the rectangular plates, the effect of steel ratio is considerable in no supporting condition, but neglible in the supporting condition. So, the effect of steel ratio should be negligible in the case of the elastically supported circular ring sector plates. 3.However, the effect of steel ratio is much more considerable in the case of the fixed supported circular plates, especially, when steel ratio being not more than 1.0% and stiffness ratio being smaller. So, the effect of steel ratio should be considered in the analysis of reinforced concreate circular ring sector plates with fixed conditions. 4.The effect of open angle is greater in the case of without-supporting beam conditions. However, in the other case of with-supporting beam conditions, the effect is a little bit when open angle of not more than 300 and negligible when open angle of not more than 30$^{\circ}$.

Background: Functional ankle instability (FAI) indicating a decrease in muscle strength, proprioception, neuromuscular control, balance and postural control function. Objective: To investigate the effect of jumping exercise on the supporting surface on the ankle muscle thickness, proprioceptive sensation, and balance in adults with FAI. Design: Randomized Controlled Trial. Methods: Twenty young people with FAI were randomly assigned to the unstable supporting surface jump group (N=10) and the stable supporting surface jump group (N=10). The intervention was conducted three times a week for eight weeks, and for 30 minutes per session. Trampoline was used as an unstable support surface and the stable support surface was carried out on a regular floor. The thickness of the tibialis anterior muscle and medial gastrocnemius muscle was measured by ultrasonography, and the proprioception of dorsiflexion and plantarflexion was measured using an electrogoniometer. The dynamic balance was also measured with a balance meter. Results: The the muscle thickness of the medial gastrocnemius muscle was significantly higher in the stable supporting surface jump group than in the unstable supporting surface jump group (p<.05). Furthermore, the plantar flexion proprioception and dynamic balance were significantly improved in the unstable supporting surface jump group than in the stable supporting surface jump group in the intergroup comparison (p<.05). Conclusions: The conclusion has been reached in this study that the jumping exercise on the unstable supporting surface could be a more effective in improving FAI than the regular surface.

This study is research for effect of the involved lower limb weight bearing training on symmetrical weight supporting rate improvement by practicing involved lower limb weight bearing training of three weeks period to improve standing equilibrium problem with asymmetric weight supporting rate of hemiplegia. In result of the study, it has shown that P-value incase of involved supporting rate is lower than level of significance $\alpha$<.05 and mean improvement rate of experienced group is higher in comparison with controlled group and experienced group. In changing quantity of involved maximum supporting rate, P-value is .26 and higher than level of significance $\alpha$<.05, and so it did not show significant difference statistically. But in case of experienced group between pre and post-test, involved side supporting rate and involved side maximum supporting rate showed significant improvement in all. In comparison of relative characteristic training effect difference, it was shown that train-learning effect on case of 40-60 years old, hemorrhagic patient and standard body bun of patient is valuable, which showed significant improvement in case of paralytic side and disease period, it did not show significant difference on excercise learning effect in two above cases. In the above result, we can say that continuous weight bearing training on the involved lower limb for three weeks period help improve the involved side supporting rate of hemiplegia. Accordingly, the weight bearing training on the involved lower limb is training method that patient can easily train with simple guidance of therapists, without being special expensive equipment. Furthermore it can be helpful to establish home therapeutic plan for hemiplegia through education of a patron.

Inner diameter of bearing race is automatically measured by complete inspection system after grinding process. Contact type three points supporting method is widely applied to automatic inner diameter measurement because of its excellent stability. However, the geometric consideration regarding three points supporting method is not sufficient. In this study, the error equation from geometric error analysis of three points supporting method is found. The effect of factors in the error equation is also investigated. The error equation is linear for difference of diameter in sample and master on range of tolerance. An error becomes more and more larger, when the distance of two supporting balls or the diameter of supporting ball are increased. In the result, some considerations are proposed for measurement of inner diameter by the three points supporting method.

중소기업은 전체 고용의 76.9%, 부가가치의 52.8%, 생산의 50.6%를 차지하고 있다는 점에 있어 국가경제 및 국가 경쟁력을 향상을 위해 기술혁신을 위한 연구개발투자(R&D)가 매우 중요하다. 이에 본 연구는 중소기업 기술혁신 분야 중 지원 과제수, 지원금액의 연구개발투자비(R&D)에 대한 경제적 성과와의 상관관계, 영향을 분석한 결과는 다음과 같다. 첫째, 중소기업기술혁신분야 연구개발(R&D) 투자가 기업의 경제적 성과를 분석한 결과, 연구개발 과제 지원수와 연구개발 지원금액은 평균 매출액 및 수출액 증대와 인력 감축 및 신규 고용창출 효과와 관련성이 있으며, 수입대체 효과와는 부적인 상관을 보였다. 둘째, 중소기업기술혁신분야 연구개발 투자가 중소기업의 경제적 성과에 미치는 영향을 분석한 결과, R&D 투자가 기업의 인력감축, 수출액 증대, 수입대체 효과, 평균 매출액 증대, 기업의 영업이익 증대 순으로 긍정적인 영향을 미치는 것으로 나타났으며, 고용창출 효과, 생산비 절감효과에는 직접적인 영향을 미치지 않는 것으로 나타났다. 이는 연구개발을 위한 지원 과제수와 지원 금액이 증가함에 따라 기업의 경제적 효과가 증가함은 물론 사회적 국가적인 경제발전에도 R&D 투자가 미치는 영향은 매우 유의미하다고 볼 수 있다. 반면 중소기업의 고용창출 및 생산비 절감을 위한 지속적인 연구개발 투자가 필요함을 시사하고 있디. 이러한 맥락에서 R&D 투자에 대한 개선 방안으로 영세 중소기업의 기술개발활동을 촉진할 수 있는 제도적 조건을 정을 정비하고, 지속적인 중소기업 연구개발을 위해 지원 금액을 지원하는 방식을 다양화할 필요성이 있으며, 연구개발 증소기업을 위해 투자용 펀드 상품을 개발하여 지원해야 중소기업기술혁신개발사업 발전방안 제안하는 데 목적이 있다.

This paper suggests the finite element method to analyze the dynamic characteristics of a rotating HDD system including the supporting structure with general shape. The flexible supporting structure was modeled by tetrahedra elements to produce a finite element model of disk-spindle-shaft-housing system and the dynamic characteristics of the HDD system was investigated due to the change of rotating speed. The validity of the presented method was verified by the modal testing. The supporting structure has an crucial effect on lower modes for HDD system, so that it is required to consider the supporting structure to accurately analyze the dynamic characteristics of HDD system.
