많은 벤처기업들이 혁신적인 아이디어를 기반으로 제품을 개발하지만, 모든 제품개발 프로젝트가 성공적이지는 않기 때문에, 무슨 제품개발 프로젝트가 어떠한 조건에서 성공할 수 있는지를 파악하는 연구가 필요하다. 이에 본 연구는 기업의 제품개발 프로젝트와 제품개발 성과와의 관계를 파악하고 있는 기존 연구들을 정리하고 전통적으로 강조되어 온 연구개발 부서, 연구개발 투자 및 연구개발 협력의 효과뿐 아니라, 지금까지 잘 논의되지 않았던 비즈니스 모델의 효과를 함께 고려하였으며, 이 요인들이 제품개발 성과에 미치는 영향을 종합적으로 분석하였다. 한국의 성장단계 벤처기업들을 대상으로 조사된 180개 기업 사례를 분석한 결과, 연구개발 부서, 연구개발 투자와 연구개발 협력으로 측정된 제품개발 프로젝트가 제품개발 성과에 미치는 직접적인 효과가 유의미하지는 않았지만, 비즈니스 모델이 제품 혁신성으로 측정된 제품개발 성과에 미치는 직접적인 효과가 유의미하게 나타났으며, 특히 비즈니스 모델이 명확하고 독창적인 경우 연구개발 투자와 상호작용하여 제품개발 시간을 단축시키는 것으로 나타났다. 이러한 분석결과는 비즈니스 모델이 명확하고 독특한 경우 비즈니스 모델이 벤처기업의 제품개발 프로젝트가 성과로 이어질 수 있게 하는 피보팅 역할을 할 수 있다는 점을 시사하는 것이다.

한국뿐만 아니라 전 세계적으로 커피의 소비는 증가하고 있다. 그에 따라 발생하는 커피부산물 또한 증가하고 있지만 이를 처리하기 위한 방안이나 기술은 현재 부족한 상태에 있으며, 부산물에 의한 환경문제 또한 그 문제점이 대두되고 있다. 이러한 환경문제를 해결하기 위해서 최근 커피부산물을 활용하기 위한 친환경적인 방법과 재활용을 목적으로 한 다양한 연구가 진행되고 있으며, 커피부산물 또한 저렴한 친환경 소재가 될 수 있어 최근까지 연구가 활발히 진행되고 있다. 본 논문에서는 커피 부산물의 종류와 특성을 이해하고, 현재까지 연구되어 온 커피부산물을 활용할 수 있는 방법에 대한 동향을 분석하였으며, 한국 내 서울시의 커피찌꺼기 현황을 파악 하고 현재 진행되고 있는 서울시의 커피찌꺼기 처리 방안에 대해 논의 하였다.

This paper aims to examine the status of sizing specifications for disposable sanitary pads on the market and to offer information on product design that reflect the requests of consumer by gathering opinion through the practical experience of consumers. Seventy-six varieties of sanitary pads on market are measured and the evaluations of wearing comfort were investigated by the questionnaire and interview for sixty three varieties of sanitary pads. As a result, they were classified into five sizes related with length but vaguely related with thickness and width. Thickness is distinguished by the compressibility that is marked as slim or ultra slim by the same brand. However, there is no sizing consistency for all products. The result shows that there is some confusion for consumers to choose desired sizes, In addition, the perception of wearing is categorized into four factors that are product performance, size and fit, wearing feeling and margin of action, and adhesive property and wrapping. The manufacturing specifications for the sanitary pads on domestic market, the requests of consumers for sanitary pad design modifications, and proposals for follow-up studies were figured out through this research.

Immobilized Candida antarctica lipase was used to catalyze the separation of ketoprofen into its components by means of esterification followed by the enzymatic hydrolysis of the ester product. In this study, ketoprofen underwent esterification to ethanol in the presence of isooctane. When the reaction was complete, 58.3% of the ketoprofen had been transformed into an ester. The ketoprofen remaining in solution after the reaction was complete consisted primarily of its S-enantiomer (83.0%), while the 59.4% of the ketoprofen component of the ester consisted of its R-enantiomer. We then subjected the ester product to enzymatic hydrolysis in the presence of the same enzyme and produced a ketoprofen product rich in the R-enantiomer; 77% of this product consisted of the R-enantiomer when 50% of the ester had been hydrolyzed, and 90% of it consisted of the R-enantiomer when 30% of the ester had been hydrolyzed. By contrast, the R-enantiomer levels only reached approximately 42 and 65%, respectively, when 50 and 30% of the racemic ester was hydrolyzed under the same conditions.

본 연구의 목적은 온라인 의류판매 쇼핑몰 상에서의 충동구매행동과 의류품목/가격간의 관계를 알아보기 위한 것이다. 인터넷 설문지를 통한 데이터 수집을 통해 731부가 본 연구에 사용되었다. 연구결과 충동구매집단이 비충동구매집단보다 셔츠/블라우스와 벨트의 품목을 유의하게 더 많이 구입하는 것으로 나타났으며, 신발을 가장 적게 구입하는 것으로 나타났다. 또한 충동구매집단이 $25 이하의 의류를 비충동구매집단보다 유의하게 더 많이 구입한 것으로 나타나 충동구매행동과 의류품목/가격간의 상관이 있음을 보여주었다.

This thesis is purposed on developing security product co-evaluation statistics administrate program which is can administrate or analysis CC accreditation product using by DEVS modeling via portal site of member of CCRA. Via developing security product evaluation statistics administrate program, it can analysis the trend of all countries of the world in many ways, and noticed the ways of evaluation and accreditation of most countries via scheme analysis. Except this, it can analysis the situation of accreditation trend of any countries via data analysis of ICCC 2009. Also, For trend analysis to evaluation technique of CCRA member, it analyzed up to date technology and policy of the evaluation organization and the Certification Authority of most countries. And it peformed analysis the most trend of information security of evaluation authorization in CCRA member countries. In this program, It provide the function of trend statistics analysis which can statically analyzed the evaluation accreditation trends of most countries and automatical statistics by categorization ( by Product, Class and statistics in national) and report creation functions which can easily extraction and use the needed data. It has been updated the related informations until latest accredited product using by CC(Common Criteria) portal home page's data.

People write reviews of numerous products or services on the Internet, in their blogs or community bulletin boards. These unstructured data contain important emotions and opinions about the author's product or service, which can provide important information for future product design or marketing. However, this text-based information cannot be evaluated quantitatively, and thus they are difficult to apply to mathematical models or optimization problems for product design and improvement. Therefore, this study proposes a method to quantitatively extract user's opinion or preference about a specific product or service by utilizing a lot of text-based information existing on the Internet or online. The extracted unstructured text information is decomposed into basic unit words, and positive rate is evaluated by using existing emotional dictionaries and additional lists proposed in this study. This can be a way to effectively utilize unstructured text data, which is being generated and stored in vast quantities, in product or service design. Finally, to verify the effectiveness of the proposed method, a case study was conducted using movie review data retrieved from a portal website. By comparing the positive rates calculated by the proposed framework with user ratings for movies, a guideline on text mining based evaluation of unstructured data is provided.

The purpose of this paper is to construct a ring with unity under the derived cup product on the cochain groups of the inverse system and an isomorphism which is useful as the computation of a derived group by deleting the suitable terms in the directed set D. Moreover we apply these results to the K-theory.
