Protein profiles of beef loin were constructed by comparing two-dimensional gel electrophoresis patterns of the proteins from different growth stages of Hanwoo, Korean cattle. Proteins from the lean muscle of 0, 6, 12 and 24 months old Hanwoo were separated by isoelectric focusing (IEF) on 16 cm tube gels, and further processed second dimensionally by 12% SDS-polyacrylamide gel electrophoresis (PAGE) using 18 × 20 ㎝ gel. Proteins with pI values ranging 3.0 to 9.0 and molecular weight of 15 to 100 kDa could be clearly detected on gel by silver staining. Interestingly, many of the proteins significantly increased and decreased during growth happened to be low molecular ones. To isolate the increased proteins, the soluble proteins were obtained from the tissue by 1% Triton X-100 extraction, then, fractionated by 30% and 50% ammonium sulfate. The isolation condition of each particular protein was determined. According to the conditions, two of the increased proteins were isolated, and transferred to PVDF membrane and microsequenced.

빠르게 변화하는 기술의 발달은 제품의 수명주기를 단축시키는 결과를 가져오게 되었다. 이와 같은 현상은 신제품 개발시 구매자와 공급자가 함께 공동으로 제품을 개발하는 중요성이 점차 증대하는 하나의 원인으로 작용하였다. 이와 더불어 성공적인 신제품 개발을 위한 조직의 역량에 대한 기존의 연구들도 활발하게 진행되었다. 그러나 기존의 연구들은 구매자의 관점에서 다루어진 구조적 지식과 공급자 선정의 중요성 등을 강조한 논문들이 대부분이며, 공급자의 관점에서 분석한 논문은 매우 제한적이다. 하지만, 신제품 개발 환경이 점차 공급자에 대한 의존도가 커지는 것을 고려할 때에 공급자의 관점에서 필요한 조직 역량에 대한 연구는 필요하다고 판단된다. 본 연구는 이와 같은 선행 연구의 부족한 부분을 보완하기 위하여 공급자 측면에서의 성공적인 신제품 개발 역량에 초점을 맞추어 실시하였다. 지식기반이론과 여러 선행연구들을 바탕으로 공급자의 협업역량은 신제품 개발 프로젝트 성과와 구매자 만족도에 긍정적인 영향을 미치고, 신제품 개발 프로젝트 성과는 구매자 만족도에 긍정적인 영향을 미칠 것으로 가설을 수립하였다. 이와 같은 가설을 검증하기 위하여 신제품 공동개발이 활발하게 발생하는 자동차, 전기, 국방산업에서 수집한 설문자료를 바탕으로 구조방정식 모형을 이용하여 분석하였다. 연구결과 공급자의 협업역량이 높을수록 신제품 개발 프로젝트 성과가 좋아지는 것으로 나타났다. 그리고 공급자의 협업역량이 높을수록 구매자의 만족도가 증가하는 것으로 밝혀졌다. 이러한 결과는 기존 연구에서 강조하였던 공급자의 기술역량과 함께 관계역량에도 많은 관심을 기울여야 하는 것을 의미한다. The development of rapidly changing technologies has resulted in shorter product life cycles. This phenomenon is one of the reasons that the purchaser and the supplier jointly develop the product together in the development of the new product. In addition, previous studies on the organization's ability to develop successful new products have been actively conducted. However, most of the previous studies emphasize the importance of structural knowledge and supplier selection in the buyer's viewpoint, and the papers analyzed from the supplier's perspective are very limited. However, considering the increasing reliance on suppliers for the new product development environment, it is necessary to study the organizational competence required from the supplier's point of view. This study focuses on successful new product development capabilities in terms of suppliers in order to complement the shortcomings of these previous studies. Based on the knowledge-based theory and several previous studies, it was hypothesized that the collaborative capabilities of suppliers have a positive effect on the performance of new product development projects and buyer satisfaction, and that the performance of new product development projects has a positive effect on buyer satisfaction. To verify this hypothesis, structural equation modeling was used to analyze the questionnaires collected from automobile, electricity, and military industries where new product development is actively occurring. The results show that the higher the supplier 's collaborative capability, the better the performance of the new product development project. The higher the supplier 's ability to collaborate, the higher the satisfaction of buyer. This result implies that we need to pay much attention to the competence of the supplier as well as the competence of the supplier, which has been emphasized in the previous studies.

구매자와 공급업체간 신제품 공동개발 과정에서 발생하는 프로젝트 모호성에 대한 연구

황선일(Sunil Hwang),허대식(Daesik Hur) 한국경영과학회 2009 한국경영과학회 학술대회논문집 Vol.2009 No.10

Buying firms often involve suppliers in their new product development projects to reduce development cost and lead time and improve manufacturability of the new product. To be successful, a supplier organization needs to understand clearly its roles and responsibilities expected by the buyer organization. Yet the supplier often complains about insufficient and unclear data, and suffers from ambiguous interpretations that contradict buyer’s expectation. We conceptualized project equivocality as perceived uncertainty arising from insufficient information, unclear definitions, conflicting interpretations, and misunderstandings of facts in carrying out relevant tasks. Although both organizations may face project equivocality, this study focused on the supplier side. Hence, we aimed to explore the antecedents to supplier-perceived, project equivocality, and its effect upon the supplier’s project performance and business performance. Underpinned in the knowledge based view of the firm, we suggested the following four antecedents: product innovation, buyer’s protectiveness of core knowledge, supplier absorptive capacity, and degree of buyer-supplier routine communication. 103 joint new product development projects were sampled from the automotive, electronics, and machinery industries in Korea to empirically test the hypotheses. A preliminary analysis revealed that product innovation and buyer’s protectiveness of core knowledge significantly increased equivocality perceived by the supplier, and in turn, that the greater equivocality negatively affected the project performance and supplier’s business performance measures

시장경쟁의 글로벌화와 소비자선호의 다양화로 인해서, 대량고객맞춤 (Mass Customization)은 소비재 산업에서 영향력 있는 경쟁전략으로 부상하고 있다. 대량고객맞춤의 핵심적인 이슈는 대량생산체제에서 가능한 저렴한 비용을 유지하면서 어떻게 소비자들이 원하는 다양한 제품들을 공급할 수 있는냐하는 것이다. 이 논문에서는 대량고객맞춤을 지향하는 기업들이 필요로 하는 신제품개발전략으로 소비자의 제품개발 참여, 공급자의 제품개발 참여, 그리고, 제품모듈화의 세가지를 제안하고, 이들 전략들이 고객만족과 직결된다고 가정하였다. 8개국 238개의 신제품개발 프로젝트에서 수집된 데이터를 통해서 실증적인 분석을 시도하고, 신제품개발전략에 대한 유용한 시사점을 도출하였다. Global market competition and ever-increasing diversity of customer demands have made mass customization an effective competitive strategy in the 21 century. The key dilemma in mass customization, through, is how product customization can be realized without increasing production cost significantly. The purpose of this study is to explore new product development strategies that facilitate mass customization. Specifically, we propose product modularity, customer involvement, and supplier involvement in new product development processes as enabling strategies for mass customization, all of which positively contribute to customer satisfaction. Data collected from 238 new product development projects in eight countries were employed to test the hypotheses, and practical implications are provided.

21세기는 아웃소싱의 시대라고 말해도 과언은 아니다. 기업경쟁의 세계화로 인해서 기업들은 아웃소싱을 통해서 고정자산에 대한 투자를 줄이고, 동시에 핵심역량의 강화에 나머지 자원을 집중적으로 투자하는 선택과 집중이 경쟁의 원칙이 되고 있다. 물류전문업체의 등장과 함께 많은 기업들이 자사물류에서 3자 물류로 전환하고 있지만, 3자 물류회사들에게 통합물류 서비스를 위탁하는 예는 많지 않은 것이 현실이다. 본 연구에서는 한국의 대표적 3자 물류회사인 한솔 CSN의 사례를 통해서, 화주기업의 통합물류 아웃소싱의 배경, 장애요인, 3자 물류회사의 역할에 대해서 심도 있는 분석을 하고, 시사점을 제시하고 있다. We live in the era of outsourcing. As the world market becomes more integrated and competition has intensified, more and more firms prefer to be `asset-light` while outsourcing non-core operations to outside specialists. In particular, logistics is the most often outsourced business processes. Yet, 3rd party logistics service firms have not been penetrated to the integrated logistics market, and many firms are still reluctant to increase their reliance on 3rd party logistics service providers. In this study, we reported a case study of Hansol CSN to shed a light on this issue, and suggested several managerial implications.

A Study on the Effect of Supplier’s Strategy on New Product Development Performance

Sunil Hwang(황선일),Eung-Kyo Suh(서응교) 한국유통과학회 2017 유통과학연구 Vol.15 No.9

Purpose – In the joint development of new products, buyers and suppliers exchange information to solve various problems. Uncertainty and ambiguity are typical examples. Uncertainty refers to the lack of information to solve the problem, and equivocality refers to the case where the information is interpreted in multiple processes in the process of providing the information. These uncertainty and equivocality cause new products to be delayed in their development and adversely affect quality. However, unfortunately, there is a lack of researches on how the uncertainty and equivocality of such concepts control the results of new product joint development. But, smooth communication and effective exchange of information is not emphasized only in the general organization. The importance of the new product joint development projects to achieve the two organizations’ common goals becomes even greater. The purposes of this study are to analyse the effect of supplier’s strategy on the NPD performance and moderating effect of uncertainty and equivocality. Research design, data, and methodology – In order to make a contribution to the lack of academic researches in Korea, this study collects data through questionnaires based on organizational information processing theory and previous studies, and conducts empirical analysis. Results – As a result, the product modularization strategy and the strategic supply chain relationship positively influenced the new product development performance - return on investment and ease of manufacturing. And the interaction effect of uncertainty and equivocality with supplier’s strategy – product modularity strategy and strategic supply chain management relationship - reduces or negates the influence of product modularization strategy on new product development performance. Conclusions – This implies that it is important to control uncertainty and equivocality in order for the supplier strategy to have a pos
