노두환,황경호,Roh, Doo-Hwan,Hwang, Kyung-Ho 한국벤처창업학회 2019 벤처창업연구 Vol.14 No.2

In Korea, small and medium sized domestic enterprises(SMEs) play an pivotal role in the national economy, accounting for 99.9% of all enterprises, 87.9% of total employment, and 48.3% of production. and SMEs was driving a real force of the development of national economy in many respects such as innovation, job creation, industrial diversity, balanced regional development. Despite their crucial role in the national development, most of SMEs suffer from a lack of R&D capabilities and equipments as well as funding capacity. Public R&D institutes can provide SMEs with valuable supplementary technological knowledge and help them build technological capacity. so, In order to effectively support SMEs, government and public R&D institutes must be a priority to know about the factors influencing the performance related to technology transfer and technological collaborations. In particular, SMEs are not only taking up a large portion of the national economy, but also their influence in politics and economy so strong that raising the competitiveness of small and medium-sized companies is a national policy goal that must be achieved in order to achieve sustained economic growth. For this reason, it is necessary to look specifically at the relationship between concepts such as the environment, strategy, and organizational culture surrounding the enterprise to enhance the competitiveness of SMEs. The paper analyzes 665 companies to find out which organizational culture affects their performance by classification and type of business of SMEs. This study demonstrated that when SMEs seek consistency in their external environment, strategies, and organizational structure to maintain their continued competitiveness. According to three-way analysis of variance (3-way ANOVA) indicates that classification of industries in SMEs has statistically significant main effects, but the type of business and organizational culture do not have significant effects. However, the company's organizational performance (operating profit) of SMES were found to differ significantly in comparison between groups according to classification standards of industries, and therefore adopted some parts. In addition, an analysis of the effect of interaction between the three independent variables of small and medium-sized enterprises has shown that there are statistically significant interaction effects among classification, types of business, and organizational cultures. The results shows that there is an organizational culture suitable for each industry classification and type of business of an entity, and is expected to be used as a basis for establishing promotion policies related to the incubation and commerciality of small and medium-sized venture companies in the future.

벌지 실험을 통한 Ti 박막의 크기 효과 관찰 및 기계적 물성 측정

정봉부(Bong-Bu Jung),이헌기(Hun-Kee Lee),황경호(Kyung-Ho Hwang),박현철(Hyun-Chul Park) 대한기계학회 2013 大韓機械學會論文集B Vol.37 No.1

본 연구에서는 벌지 실험을 이용하여 티타늄 박막의 기계적 물성을 측정하였다. 벌지 실험은 외적 지지구조를 가지지 않는 박막 시편의 한 면에 일정한 압력을 가하여 박막의 변위를 측정, 압력과 변위의 관계를 이용하여 박막의 기계적 물성을 측정하는 실험이다. 스퍼터링을 이용해 증착된 티타늄 박막의 두께는 1.0, 1.5, 2.0 ㎛ 이고, 물성의 열처리 시간에 대한 영향을 알아보기 위해 증착된 시편은 600 ℃에서 각각 150, 300, 600 초 동안 열처리 되었다. 박막의 탄성 계수, 잔류 응력, 항복 응력이 벌지 실험을 통해 측정되었고, 실험 결과 항복 응력은 열처리 시간에 의존하는 특성을 확인하였다. 또한 시편 두께가 감소할수록 강도가 증가하는 크기효과를 관찰하였다. In this study, the mechanical properties of a Ti thin film are measured by a bulge test. In the bulge test, uniform pressure is applied to one side of the film. Measurement of the membrane deflection as a function of the applied pressure allows one to determine the mechanical properties of the film. Ti thin films with thicknesses of 1.0, 1.5, and 2.0 ㎛ were deposited on a Si wafer by using an RF magnetron sputtering system. These specimens were annealed at 600 ℃ for 150, 300, and 600 s to investigate the effect of temperature on the yield stress and mechanical properties of the Ti films. The elastic modulus, residual stress, and yield stress of these membranes are measured by a bulge test. The experimental results suggest that the yield stress is sensitive to the film thickness and annealing time.
