This study investigates how cognitive and affective conflict affect performance and social outcomes in the new product situation. We examine the corporate, project, and personal characteristics that determine the level of inter-functional conflict between marketing and R&D. From a survey of Korean high-tech companies, we found : (1) time pressure was positively related to cognitive and affective conflict, (2) joint reward systems, interdepartmental connectedness, and years of education were negatively associated to cognitive conflict, (3) while cognitive conflict was positively related to new product creativity and NPD performance, affective conflict was negatively associated to marketing-R&D integration and perceived effectiveness of the relationship, as well as new product creativity and NPD performance.

The engineering knowledge and technology is core driving forces of continuous growth in knowledge based society. Companies, the government, and universities are the subjects of an innovation and the cooperation between them is very important. Nowadays, the main purpose of industry-university cooperation moves to train experts and develop a new product. A shift of the paradigm came from the change of recognition that the final consumers of the program are companies and the universities are supporters of the program. In this paper, we investigate the purpose, participation and satisfaction of companies to industry-academy technology cooperation through empirical studies. The need to expert training, product development and process development makes companies participate industry-academy technology cooperation and companies have different purpose of participation by the business type. Companies often feel that expert training, subsidiary purpose of industry-academy technology cooperation, is more important than product development or process development. This result is caused by the real world environment of small and mid-size companies, lacking of technology experts. The participation of companies to each technology cooperation program (technology transfer, joint technology development, consigned technology development, technology consulting, co-op. lab.) is also different by business type. The companies' satisfaction with the purpose of process development is relatively higher than that with the purpose of product development and companies show also different satisfaction value by business type and participating program. The results of this study can give a contribution to the design of demand oriented industry-academy technology cooperation model.

최근 많은 기업들이 서로간의 신뢰를 바탕으로 협력관계를 구축해 나가고 있다. 이렇게 형성된 파트너와의 관계는 좋은 성과를 거두는데 중요한 역할을 하고 있으며, 특히 공동으로 상품을 개발하는데 많은 도움이 되고 있다. 따라서 본 연구에서는 거래업체 사이의 거래관계에 있어 중요한 요소 중 하나인 의사소통이 성과에 어떠한 영향을 미치는지 확인해 보았다. 분석결과 거래업체 사이의 의사소통은 신뢰에 긍정적인 영향을 주며 반대로 갈등에는 부정적인 것으로 확인되었다. 또한 관계 파트너에 대한 신뢰는 협력과 신제품성과에 긍정적인 영향을 주는 것으로 나타났지만, 갈등은 부정적인 영향을 주는 것으로 확인되었다. 즉, 기업간의 관계에서 신뢰형성은 좋은 성과를 가져오지만, 반대로 서로간의 갈등이 커지면 성과는 감소하게 된다. 따라서 거래업체 사이에 발생하는 갈등은 원만하게 해결하고 신뢰를 통해 협력관계를 형성하게 된다면 신제품 개발 시 좋은 성과를 얻을 수 있을 것이다.

KUH-1에 적용되는 질소충전트레일러는 항공기의 주/전륜 완충기, 테일범퍼완충기, 브레이크 축압기, 타이어 등에 질소를 충전하는 장비이다. 명칭에서 알 수 있는 것과 같이 질소충전트레일러는 질소 충전과 더불어 이동성을 가지고 있는 장비이다. 기존 미국의 Tronair사에서 독점 공급하여 국내에서는 수입에 의존하던 품목이며, 본 국산화 개발품은 도입품의 성능을 만족할 뿐만 아니라 운용 시 도입품보다 용이하도록 설계를 추진하였다. 제15-4차 민관공동투자사업으로 선정되어 개발이 진행되었으며, 민관투자기업인 한국항공우주산업과 국방기술품질원의 개발관리 지원하에 개발요구도 분석 및 시험평가가 수행되었으며, 2017년 5월 군사용 적합 판정 결과 승인을 받았다.

The aim of this paper is to present the development of visual seam tracking system equipped with visual range finder. The visual range finder, which consists of a CCD camera and a diode laser system with line generating optics, developed to recognize the types of weld joints and detect the location of weld joints. In practical applications, however, images of the weld joints are often degraded due to spatters, are flares, surface specularity, and welding smoke. To overcome the problem, this paper proposes a syntactic approach which is a class of artificial intelligence techniques. In the approach, the type of weld joint is inferred based upon the production rules which are linguiques grammars consisting of a set of line and junction primitives of laser strip image projected on weld joint. The production rules eliminate several noisy primitives to create new primitives through the merging process of primitives. After the recognition of weld joint, arc welding is started and the location of weld joints is repeatedly detected using a spring model-based template matching in which the template model is a by-product of the recognition process of weld joint. To show the effectiveness of the proposed approach a series of experiments-identification and robotic tracking-are conducted for four different types of weld joints.

최근에는 소프트웨어개발 프로세스나 도구보다는 개인과의 상호작용을 희망하고, 고객은 포괄적인 문서보다는 우선 작동하는 소프트웨어를 희망하며, 개발자는 계약에 대한 협상보다는 고객과의 협력을, 서로가 계획을 고수하기 보다는 변화에 대응하는 것을 더욱 가치 있게 생각한다. 이러한 관점에서, 소프트웨어 개발은 프로세스 중심보다는 프로젝트팀에게 자율성과 동기를 부여하고, 열정과 비전 등 인간관계 중심의 관리방식이 요구되고 있다. 최근에 와서 애자일 개발프로세스가 생산성 증대효과, 품질향상, 고객만족 등의 효용성이 입증되면서 프로젝트를 추진 할 때 방법론 선택에 있어, 전문가들에게 주목을 받게 되었다. 시대적 요구와 사용자 요구에 부응하기 위한 방법론 선정과 관련, 본 논문에서는 조직 구성에 있어, 제품 기반의 Cross functional team의 문제점을 해결하고자 제안된 방법론이 Feature Team 모델이며, 이 모델이 Cross functional team을 조직하고, 이 팀이 결과물(프로덕트) 단위가 아니라, 기능단위로 여러 프로덕트에 걸쳐서 개발을 진행하는 모델이라는 점에 대해 조사하였으며, 가치-주도형 애자일 기법을 통해 계획-기반형 모델과 차이점을 제시하였다. 그리고 객체지향모델링을 위해서는 기존의 JAD(joint application development)회의가 목표로 하는 도메인 분석, 요구추출, 모델링과 정리, 검토과정에 있어, UML 구조도와 행동도를 사전에 숙지하고 프로젝트를 진행하도록 제안한다.

We present the performance test results of VLBI Correlation Subsystem (VCS) trial product which was being developed for 1 year from August 2007. It is a core component of Korea-Japan Joint VLBI Correlator (KJJVC). The aim for developing VCS trial product is to improve the performance of VCS main product to reduce the efforts and cost, and to solve the design problems by performing the preliminary test of the manufactured trial product. The function of VCS trial product is that it is able to process the 2 stations-1 baseline, 8 Gbps/station speed, 1.2 Gbps output speed with FX-type. VCS trial product consists of Read Data Control Board (RDC), Fourier Transform Board (FTB), and Correlation and Accumulation Board (CAB). Almost main functions are integrated in the FTB and CAB board. In order to confirm the performance of VCS trial product functions, the spectral analysis, delay compensation and correlation processing experiments were carried out by using simulation and real observation data. We found that the overflow problem of re-quantization after FFT processing was occurred in the delay compensation experiment. We confirmed that this problem was caused by valid bit-expression of the re-quantized data. To solve this problem, the novel method will be applied to VCS main product. The effectiveness of VCS trial product has been verified through the preliminary experimental results, but the overflow problem was occurred.

To overcome many defects such as the high product cost, large energy consumption, and big space capacity in conventional mechanical machining, the miniaturization of machine tool and micro factory systems has been envisioned recently. The object of this paper is to research the effect of dynamic characteristic parameters in bolted-joint beams, which is widely applied to the joining of mechanical structures in order to identify structural system characteristics and to predict dynamic behavior according to scale-down from macro to micro system as the development of micro/meso-scale machine tool and micro factories. Modal parameters such as the natural frequency, damping ratio, and mode shape from modal testing and dynamic characteristics from finite element analysis are extracted with all 12 test beam models by materials, by size, and by joining condition, and then the results obtained by both methods are compared.

The yoke, a component of conventional motor-driven power steering system, often contains welding defects from its manufacturing process. To eliminate these defects, the precision cold forging process has been tried. In this study, the double-action complex forging has been used to manufacture a torsion joint yoke. The backward extrusion proved faster than the forward extrusion in forging of the product. The double-action complex forging process utilized an upper die composed of a punch, a punch guide, a disc spring and a coil spring. The forged material pushes up the punch guide, and then the disc spring and the coil spring balances the backward extrusion force. Consequently, the flow of material was essentially in the forward direction, resulting in a successful forging operation. The forging load of Al 6061-T6 was higher than that of the automotive structural hot rolled plate.
