In the case of SMEs, entrepreneurship that organizes only core functions with the minimum number of people is increasing, and a responsibility management system focusing on core functions is emphasized, so that the interest in innovation behavior and survival strategy of enterprises is getting bigger. However, in the case of SMEs, it is not easy to pursue continuous innovation due to lack of capital and lack of professional manpower. The purpose of this study is to investigate the effect of SME on innovation behavior by selecting exploratory study and literature study for SMEs. The data for this study were 545 out of the total 600 copies distributed to employees in SMEs. The data were analyzed using SPSS 21.0 and amos18.0. First, product diversification, strategy formulation, and R & D have a significant effect on innovation behavior, and market diversification has no effect on innovation behavior. Second, working variables such as product diversification, market diversification, strategy formulation, and R & D do not control the influence of innovative behavior on innovation behavior. Third, the rank variable, which is the controlling variable, controls the magnitude of the effect of product diversification, market diversification, strategy formulation, and R & D on innovation behavior. As a result, corporate managers should lead the organization in order to promote product diversification, market diversification strategy, R & D and innovation activities. After discussing the conclusions and implications of this study, this study presented the direction of the research for the follow-up study.

For keeping the indoor air quality, we develop the pulsating heat pipe(PHP) type heat recovery ventilator using an used radiator for vehicles. We compare the PHP type with existing model. There are some merits that are able to change the unit number according to heat load and show us the similar performance to existing models.

A frontal offset impact model Oat can simulate the 40% offset frontal impact into deformable barrier regulated in EU Directive 96/79 EC has been developed. Engine rotation effects are also considered in the model. Distributed 11 masses and characteristics of 23 nonlinear springs comprising the model are determined based on both the stick-model analysis under the general specification of car and the dynamic characteristics of car structure. It is demonstrated that simulated acceleration-time curve for passenger part is in good agreement with test data obtained by NHTSA.

동북아 경제중심추진위원회는 오는 4월 1일로 출범 1년이 되어간다. 동북아 경제중심의 금융, R&D, 물류 3분야 중 물류분야가 가장 먼저 로드맵이 발표되면서 공격적인 활동에 들어가고 있다. 짧은 시간 내의 활동사항을 보면 기대이상의 결과라 할 수 있다. 그러나 밑그림만 제시된 것이지 구체화되기 위해선 많이 부족하다며, 이 위원장은 휴일도 없이 전국을 돌며 물류 관계자들을 만나고 있다. 동북아 물류중심 로드맵을 홍보하고, 설득하는 한편, 기업 경영인으로서 회사업무에도 적극적으로 활동하고 있다. 이재희 위원장은 유니레버 코리아 회장을 겸임하고 있다. 그가 이 회사에 1999년 처음 취임할 당시 유니레버 코리아는 존폐의 기로에 있었지만, 이 위원장 특유의 ‘할 수 있다’는 자신감과 ‘승리정신(The Winning Spirit)'' 의 경영스타일로 오늘의 회사로 이끌었다. 이러한 경영스타일은 동북아 물류중심국가 건설을 위한 활동에도 배어있어 2006년 내에 가시적인 성과를 거두겠다는 목표로 그 누구보다도 열정적으로 활동하고 있다. (사)한국물류협회가 올해로 창립 20주년을 맞이하여 기획인터뷰 그 두 번째로 이재희 동북아 경제중심추진위원회 물류분과위원회 위원장을 만나보았다.

최근의 국제적인 폴리에스테르의 공급과잉과 가격하락 추세가 지속됨에 따라 화섬업계에서는 생존차원에서 어떻게 기존의 폴리에스테르 품질수준을 유지하면서 생산원가 절감을 통한 경쟁력을 확보하느냐에 최대의 관심이 집중되고 있다. 또 80년대에 들어서면서 선진국을 중심으로 formal wear보다 sports, leisure wear 시장이 높은 성장을 하게되었고, 최근에는 소비자들의 관심이 광택이나 만짐새등의 심리적인 쾌적성과 보온성 및 흡수성 등의 생리적인 쾌적성 등 기능성에 대한 관심이 고조되고 있으며, 다양화, 개성화의 시대인 현대는 특히 색상이나 디자인 면에서 독특한 소재의 요구가 증대되고 있다.

In this paper, new directional couplers for T/R switch of UHF RFID applications are proposed to overcome TX-to-RX leakage problem. The proposed method can remove TX-to-RX leakage caused by both imperfect isolation characteristic of the conventional directional coupler and the mismatch of antenna impedance. Two directional couplers are implemented using distributed elements and lumped elements respectively for the verification. The varactor tuneable circuits for compensation of the antenna mismatch is also proposed. The measurement result shows excellent TX-to-RX leakage suppression, more than 45dB in 910MHz.

The basic experiments on the plastic sea eel pots used in fishing were carried out in order to investigate the elasticity of the funnel ribs, hydrodynamic resistance, sinking time and diffusion of the bait from June to October, 1987. The elasticity of the bamboo funnel ribs was higher than that of the polypropylene ribs up to the load 150g. The hydrodynamic resistance R (kg) of the pots towing to the head direction horizontally in relation to towing velocity V (m/sec) was expressed as following formula; R=0.36V super(2.01) and coefficient of drag C sub(D) was 0.52. The sinking times of the covered pots by tape fully or partially were late 1-2 second than the typical pots within the water depth 7.5m. The diffusion tendency through the covered pots using dye and sardine extracts solution was concentrated to the entrance more than the typical pots. However, fishing efficiency as number and weight of fish per pots for nine times fishing operation was revealed no difference between the covered pots and the typical pots.

The purpose of this study was to investigate the distribution of tensile stress of canal obturated maxillary second premolar with access cavity and notch-shaped class V cavity restored with composite resin using a 3D finite element analysis. The tested groups were classified as 8 situations by only access cavity or access cavity with notch-shaped class V cavity (S or N), loading condition (L1 or L2), and with or without glass ionomer cement base (R1 or R2). A static load of 500 N was applied at buccal and palatal cusps. Notch-shaped cavity and access cavity were filled microhybrid composite resin (Z100) with or without GIC base (Fuji II LC). The tensile stresses presented in the buccal cervical area, palatal cervical area and occlusal surface were analyzed using ANSYS. Tensile stress distributions were similar regardless of base. When the load was applied on the buccal cusp, excessive high tensile stress was concentrated around the loading point and along the central groove of occlusal surface. The tensile stress values of the tooth with class Ⅴ cavity were slightly higher than that of the tooth without class V cavity. When the load was applied the palatal cusp, excessive high tensile stress was concentrated around the loading point and along the central groove of occlusal surface. The tensile stress values of the tooth without class V cavity were slightly higher than that of the tooth with class V cavity.

In order to understand the impacts of the construction of artificial sea dikes on carbon cycle in Samangeum area being a closed environment after April, 2006, we had measured suspended particulate matters, particulate and dissolved organic carbon in the surface water of inner Saemangeum dike from 2003 to 2006. The significant inputs of suspended particulate matter and organic carbon were mainly occurred during the wet season which suggests that most organic matter loading is concentrated within a short period of time inside the dike. The concentrations of particulate matter and organic carbon have gradually increasing every year inside of dike from the Mangyeong river estuary to Saemangeum dike, which has been closed since 2003 after the construction of the 4th dike. The particulate organic carbon increased due to the phytoplankton blooms by eutrophication. If the large portion of particulate organic matter produced in the surface water sink to the bottom sediment, this will cause the anoxic condition in this closed environment.
