As the open innovation paradigm spreads, the ability to search for new external knowledge and combine it with the organization's existing knowledge has been cosidered to play an important role in improving business performance of a company. This study empirically analyzed the influence of such organizational variables as empowering leadership, organizational learning culture, and interdepartmental cooperation on business performance of innovative technology SMEs focusing on the mediating effects of absorption capacity. For this purpose, a survey was conducted on 15,227 INNOBIZ SMEs, and 326 usable questionnaires were collected and analyzed using the structural equation model. Statistical analyses showed that the direct influence of empowering leadership, organizational learning culture, and interdepartmental cooperation on business performance was not found, but indirect effects of three organizational variables on business performance proved significant using absorption capacity as a mediating variable. This result also indicates that empowering leadership, organizational learning culture, and interdepartmental cooperation are important antecedent variables of absorption capacity.

We characterized the properties of the fabricated filter with the total internal reflection mirror (TIR) in the rectangular ring resonator and very small multimode interference (MMI) couplers on an InP material platform for photonic integrated circuits. Coupling power in and out of a resonator is increased by using an optimum MMI length of 110 ${\mu}m$ and a width of 9 ${\mu}m$, respectively. The semiconductor optical amplifier with the length of 120 ${\mu}m$ is integrated in the resonator to compensate the loss of the internal waveguide and the TIR mirror. A free spectral range of approximately 2 nm (244 GHz) is observed with an on-off ratio of 13 dB. The curve fitting also yields the power coupled per pass as 42%. To reach critical coupling at this coupling level would require a round trip loss of about 2.4 dB.

본 논문에서는 TI(Texas Instruments)사의 DSP칩 TMS320F240을 이용한 벡터드라이브 설계를 한다. TMS320F240은 서보모터드 라이브에 적합하게 상품화 된 칩으로 산업용 로봇제어에 필요한 대부분의 주변회로를 포함하고 있다. 이를 이용해서 제어기를 구성하면 적은 비용으로 신뢰성 높은 제어기를 구성할 수 있다. 드라이브는 크게 제어회로부와 파워회로부로 나누어서 설계했으며, AC서보모터에 벡터제어로 실제적용을 했다.

한국경제의 원동력이 되고 있는 벤처기업의 나라사랑이 남다르다. IMF때는 어려운 경기를 회복시키는데 일조하고, 청년실업이 심각한 요즘은 1인1사 채용운동을 통해 실업해소에 발 벗고 나서고 있다. 또한 기술수출로 외화를 벌어드리고, 신기술로 대한민국의 이름을 영광스럽게 한다. 뿐만 아니라 국내 기술을 지키기 위해 외국기업의 군침도는 인수제안을 거절하는 한편 미래의 인재를 키우기 위한 교육사업에도 열의를 보인다. 다양한 방면에서 애국을 실천하고 있는 대한민국의 파워, 벤처의 애국열전을 살펴보자.

충북도는 오리사육 비중이 우리나라에서 전남, 전북 다음으로 많은 전국 3위를 차지하고 있으며 종오리장 14개, 도축장 2개, 계열사 본사는 3개 소가 위치한 오리산업이 발달한 지역이다. 특히 충북도는 한반도의 중심에 위치하고 있고 축산 물동량이 많으며 축산차량의 경유지에 해당하여 충북도에서 가축전염병이 발생 시 전국적으로 확산될 수 있는 방역적으로 중요한 위치를 차지한다고 볼 수 있다. 철통방역으로 청정도를 실현하고 있는 충북도의 방역정책을 책임지고 있는 지용현 충북도청 동물방역과장을 만나 오리 방역정책에 대해 자세히 들어봤다.

As one of the image symbols, the second frame has rich symbolic metaphor. In previous studies, second frames are mostly presented in physical forms such as doors, windows, but in <The Power of the Dog>, there are various forms of second frames, providing more types for the study of second frames. Panofsky's Iconology has put forward a rigorous research method on how to interpret the meaning of image symbols in the picture. This study aims to use Panofsky's Iconology to analyze the second frame in <the Power of the dog>. The purpose is to expand the methodology of film image research and break through the problem that the Iconology analysis of film image stays in narrative analysis (iconographical analysis). It can be seen from the results of this study that the second frame has different visual presentation according to the requirements of narrative. In the narrative of the film, it symbolizes the depressed tone of the film and the stressful relationship between different characters. What director Campion wants to show through the second frame is that in the film industry where the problem of women is getting better, the motif of feminist film creation has changed from the expression of female appeals in binary opposition to the expression of the appeals of diverse groups in "decentralization."

This study was conducted to collect the basic data to provide for the purpose of the development of dental field. This research is to find the relationship between the level of recognized empowerment of hygienists working in dental clinics and the factors influencing on work achievement in the system of dental clinics. The population of the research is some randomely chosen dental clinics located in Seoul City during the period from March 22 to April 30, 2010, and the sample of 256 female dental hygienists working in the field were recruited as the analysis object group. The data on general characteristics and empowerment were collected by a questionnaire survey. The collected data were analyzed with the SPSS WIN 12.0 program. The following shows the results of this study. 1. The empowerment level of the analysis subject group was 3.63. It is significant statistically that the longer working career or higher annual salary, the higher empowerment level (p<0.05). 2. It shows the high level of empowerment in the group of hygienists who are in education counsel (p<0.01), and who have a permanent job (p<0.05) than others. 3. There is a significant correlation among capability, age, career, annual salary (p<0.01). 4. There is a significant correlation among self determination, age(p<0.05), career (p<0.01), annual salary (p<0.05). 5. In regression analysis, career is proved as one of the significant factors that is related to the empowerment in dental hygienists (p<0.05). This finding shows high level of empowerment in dental hygienists who hold high level of career, annual salary, education counsel jobs, or permanent jobs. Therefore, I suggest with the result of the study that the organization of dental clinic needs to improve its capability and efficiency with the efficient manpower management. Particularly, there need to be various kinds of leadership-trainning and education-program development to enhance empowerment in hygienists as professionals through independent self-decision making experiences and role do experiences.

Reinforced braid layer (RBL) in automobile power steering hose plays an important role in power steering system. When the working oil is applied to the power steering hose, RBL suppresses rubber hose deformation from internal pressure and heat expansion. RBL is woven textile composites having a double-row structure of nylon cords twisted with the specific helix angle. In this paper, effective material properties of RBL are estimated using a detailed 3-D finite element model considering its complicated geometry. Numerical experiments based on a superposition method are carried out to simulate uniaxial tensile loading condition.
