The function of product design has been an important part for success on new product development We deeply studied 'Chocolate-Phone' case which is considered as a representative of adopting design-oriented new product development strategy. According to this study, we found three contextual factors and nine key success factors for design-oriented new product development. The contextual factors consist of the strong needs for innovative product development, customer's needs for the emotional value, competitive situation for the new product launching. The key success factors consist of design, development marketing, overall sides. The key success factors of design side are to select talented designers and take an insight for market and communication skill. The key success factors of development side are to possess high technological abilities, to do divergence with removing or giving up some function management's strong support. The key success factors of marketing side are to bring core marketers from outside, capacity to gather ideas from outside. The key success factors of overall side are to share design-oriented principle with other parts and to change member's mind from engineer-oriented to market-oriented.

사용자와 감성적인 소통(Emotional Communication)이 중요한 제품 디자인 영역에서 디자이너가 사용자 감성을 보다 명확하고 신속하게 파악하는 것은 제품 디자인 연구의 매우 핵심적인 활동이다. 이에 본 연구는 제품디자인과정에 감성측정의 활용가능성을 높이기 위한 방법으로서 행위적 감성 측정 방법인 표정 부호화 시스템(Facial Action Coding System, FACS)을 제품디자인 평가에 활용하였다. 표본으로 선정한 감성 제품의 Image Map을 활용하여 긍정적, 부정적, 중성 감성을 유발하는 제품 자극물 총 6개를 선정하여 20대 일반 제품 사용자를 실험 대상으로 FACS 실험을 진행하고 사용자 얼굴 표정을 통하여 자극물에 대한 감성상태를 분석하였다. 이러한 실험을 통하여 표정 부호화 시스템이 제품디자인에 적용 과정에서 "사용자 무의식적인 얼굴 표정을 기록할 수 있다" 등 장단점을 분석하였으며 "사용자 반응도 높은 제품 자극물을 선정해야 한다" 등 적용방안을 제시하였다. 본 연구는 향후 새로운 제품을 시장에 출시하기 전에 제품디자인 시안 단계에서 사전 사용자 감성 예측 방법으로 FACS를 활용성 검토에 도움을 줄 것으로 전망된다.

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.

Solid lipid nanoparticles (SLNs) have emerged to combine the advantages of polymeric nanoparticles and lipid emulsions in early 1990s. SLNs can present several desirable properties derived from the solid state core. When formulating SLNs, there should be careful considerations about the physical state of the inner solid lipid core and its polymorphism and supercooling behavior. In this review, SLNs were compared to lipid emulsion and emulsion of supercooled melt to understand the unusual behaviors compared to lipid emulsions and to have insights into stability and release mechanism. SLNs have been regarded as biocompatible system because lipids are usually well-tolerable ingredients than polymers. Several studies showed good tolerability of SLNs in terms of cytotoxicity and hemolysis. Similar to various other nanoparticulate drug delivery systems, SLNs can also change biodistribution of the incorporated drugs in a way to enhance therapeutic effect. Most of all, large scale production of SLNs was extablished wihtout using organic solvents. Although there is no SLN product in the market till date, several advantagious properties of SLNs and the progress we have seen so far would make commercial product of SLNs possible before long and encourage research community to apply SLN-based formulations for water-insoluble drugs.

Purpose - Based on transaction cost perspective and institution-based perspective, this research attempts to investigate the effect of outsourcing on a firm's performance and how it interacts with institutional context in which the firms operate. Research design, data, and methodology -With a sample of 164 manufacturing firms form South Korea, we examine the direct effects of outsourcing on the a firm's level of product innovation and internationalization and the moderating effects of competitive pressure and property right protection as important external factors that could affect the effectiveness of outsourcing decision. Result - The findings show that outsourcing not only enhance a firm's capability to concentrate on its core competencies, but also to increase a firm's combinative capacity to acquire external knowledge. Furthermore, we finds that in a highly competitive environment, potential knowledge spillovers to other competitors may attenuate the potential benefits of outsourcing. Conclusion - Outsourcing can enhance a firm's innovation activities by providing valuable access to external knowledge and also to complementary resources from the external partners, which in turn enables firms to focus on core competences.

온화한 조건($80{\sim}110^{\circ}C$, 대기압)하에서 비누화반응에 의해 폐 PBT의 입자를 해중합하여다. PBT의 해중합은 KOH 보다 NaOH가 보다 효과적이었으며, 반응온도가 증가하고 입자의 크기가 작을수록 해중합은 증가하였다. 해중합속도는 표면반응이 율속단계로서 PBT 입자표면에 생성물이 형성되지 않은 미반응핵 모델에 의해 표현할수 있었다. 겉보기활성화에너지는 98.1KJ/mol 이었으며, 85.1, $105{\mu}m$인 PBT 입자를 6시간 동안 해중합하였을때 TPA의 회수율은 약 95%정도였다.

In many fields, the human sensibility ergonomics has applied to the product development for user's satisfaction. Also, it may use to lots of products and environments related to human convenient life. If the measurement and the validation of human sensibility are accomplished subjectively and qualitatively, then a good result is expected. Under the very competitive products development, designers applying with human sensibility ergonomics has faced with lots of problems including lack of experience, time, cost, and knowledge. In this study, a method of design for human sensibility application system is presented. In this study, a method of design for human sensibility application system is presented. Information element database such as adjectives, sensitivities, functions, and design factors is conducted, and design of system development including product development mechanism is produced. Also, the requirements and the specifications of this development model are discussed to develop the qualified implementation system.

본 연구는 반도체 설계전문기업의 경쟁력수준을 분석하는 데 초점을 맞추고 있다. 해당 기업의 경쟁력은 제품개발, 축적기술, 시장관련능력, 인적자원 그리고 경영시스템 등의 범주에서 분석하였다. 분석대상은 73개 기업으로 하였고, 이들 기업의 자료는 설문지 수거와 직접 응답방식을 병행하여 수집하였다. 설문은 명목척도를 활용하여 경쟁력 범주에 대한 중요도 순위와 경쟁력 범주별 세부항목의 수준(100점 기준)에 대하여 응답하도록 구성하였다. 분석결과, 중요하다고 인식하고 있는 경쟁력 범주와 실제 간에는 차이가 존재하고 있었다. 경쟁력 범주에 대한 중요도 인식순위는 제품개발, 축적기술, 시장관련능력, 인적자원 그리고 경영시스템 등으로 나타났다. 그러나 실제 현실적인 경쟁력 수준은 인적자원역량의 경쟁력이 가장 높았고, 그 다음으로 경영시스템, 제품개발 및 축적기술 등의 순으로 확인되었다. 가장 경쟁력이 취약한 범주는 시장관련역량으로, 이 범주의 경쟁력 제고(고객층 발굴, 시장 및 고객정보수집, 관련 정보분석 등)를 위한 노력이 더욱 필요하다고 볼 수 있다.
