명태어장에 있어서 어장형성 여부 및 어장의 어군밀도를 평가하기 위해서는 어군의 분포와 밀도에 영향을 미치는 여러 가지 해양환경인자를 동시에 고려하여 정량적인 해석이 이루어져야 한다. 그러나, 기존의 연구들은 어군의 분포 및 밀도에 영향을 미치는 개개의 해양환경인자와 어군의 분포 및 밀도와의 관계를 구명한 것이며, 어장형성 여부 및 어장의 어군밀도를 정성적인 방법으로 평가한 것으로 정량적 해석이 불가능하거나 한계가 있다. (중략)

기업의 원활한 활동에 필수적인 요소는 살아 있는 정보의 공급이며, 기업 데이터 베이스는 데이터의 보관/흐름/활용 입장에서의 정보 인프라를 기반으로 하고 있다. 최근 기업 Knowledge Base 구축은 정보의 품질이 좌우하나 기업 정보의 양은 비대해져 데이터의 일관성이 결여되고 DB 의 성능은 점점 저하되고 있다. 본 고에서는 데이터 Hub 의 적용을 통해 얻을 수 있는 DB 성능 향상에 대해 정성적/정량적 관점으로 논의한다.

The yield strength of particle-reinforced composites increases as the size of the particle decreases. This kind of length scale has been mainly attributed to the geometrically necessary dislocation punched around the particle as a result of the mismatch of the thermal expansion coefficients of the particle and the matrix when the composites are cooled down after consolidation. In this study, two dislocation-punching theories that can be used in continuum structural modeling are assessed numerically. The two theories, presented by Shibata et al. and Dunand and Mortensen, calculate the size of the dislocationpunched zone. The composite yield strengths predicted by finite element analysis were qualitatively compared with experimental results. When the size of the particle is less than $2{\mu}m$, the patterns of the composite strength are quite different. The results obtained by Shibata et al. are in qualitatively better agreement with the experimental results.

The new plan for the current computer engineering involved in education and research in the values of the major and one of the female students, and you can improve your major satisfaction and retention training and development assessment process is the point of need. in computer engineering majors can be linked to the process of targeted quantitative and qualitative research conducted by the results of major and career choices of students turned out to be a mismatch could result in the phenomenon of female engineering escape. How to study ICT in education for female students to computer engineering major regional, historical and social context should be re-designed to suit the characteristics and analysis of exposed female students majoring computer engineering from anxiety and weak organization that has a sense of belonging, and to offer the first and is the appropriate teaching methods seems to be.

Recently, the Project Financing industry has appeared the various change of the development environment in the rapid growth. So the Project Financing company has been trying to search Project Financing able to success and they are performing diversified researching to prepare the judgment ground of success from initial stage of development. The aim of this study is to find success factors which is in the Project Financing through collecting opinion of specialist and talking survey to people employed in Project Financing development field. Consequently, we indicate success factors using Analytic Hierarchy process (AHP) and make out success factors for the Project Financing. Furthermore, we suggest the way which is able to apply factors objectified so that exceed the development success Project Financing objectively.

In this paper, we present a new fuzzy information retrieval method based on thesaurus. In the proposed method th thesaurus is represented by a fuzzy linguistic matrix, where the elements in fuzzy linguistic matrix represent a qualitative linguistic values between terms. In the fuzzy linguistic matrix, there are three kinds of fuzzy relationships between terms, i.e., similar relation, hierarchical relation, and associative relation. The implicit fuzzy relationships between terms are inferred by the transitive closure of the fuzzy linguistic matrix based on fuzzy theory. And the proposed method has the capability to deal with a qualitative linguistic weights in a query and in indexing of information items to reflect qualitative measure of human based on vague and uncertain decisions rather than a quantitiative measure. Therefore the proposed method is more flexible than the ones presented in papers[1-3]. Moreover our method is more effectual of time than the ones presented in papers[1-3] because we use a fuzzy linguistic matrix and AON (Associate Ordinary Number) values in query evaluation process. As a result, the proposed method allows the users to perform fuzzy queries in a more flexible and more intelligent manner.

Recently, the Online Game industry has appeared the various change of the development environment in the rapid growth. So the online game company has been trying to search games able to success and they are performing diversified researching to prepare the judgment ground of success from initial stage of development. The aim of this study is to find success factors which is in the process from development to distribute for the online game through collecting opinions of specialist and taking survey to people employed in online game development field. Consequently, we indicate success factors using Analytic Hierarchy Process (AHP) and make out success factors for the online games. Furthermore, we suggest the way which is able to apply factors objectified so that exceed the limit of using it to the company planning to develop successful games objectively.

The existing research on domestic e-government trends in Korea has weaknesses in that it depends only on qualitative research methods. Therefore, a quantitative analysis was conducted through this study as of September 2018 based on the data from 1996 to 2017. A total of seven research topics were derived from text mining, of which the network centrality of the framework and public policy effect were identified as highly significant. The results of this study provide academic and policy implications for the development of e-government. including that using a quantitative analysis method instead of a qualitative method contributes to ensuring relative objectivity and diversity of learning.

글로벌 물산업의 규모는 2019년 기준 약 1,000조원 수준으로 2024년까지 연평균 3.5%의 성장률을 달성할 것으로 예측하고 있다. 특히 코로나 19의 영향으로 디지털 물산업에 대한 투자가 증가하고 있으며 4차산업혁명 등으로 지속 성장이 예상되고 있다. 이러한 디지털 물산업 시장의 성장은 물산업분야의 기술경쟁력의 중요도가 더욱 높아질 것을 예상하게 한다. 우리나라의 물산업에 있어서 기술경쟁력 분석을 위해 많은 연구가 진행되어왔으나 대부분 설문조사에 근거한 정석적 분석에 의존하여 왔다. 정성적인 분석에 의존한 연구의 경우, 대상 응답자들이 특정 분야에 치중되어 분석되거나 긍정적으로 판단하는 경향이 있어 우리나라의 물산업 기술의 현재 상황을 과대평가할 가능성이 있다. 또한 연구시점, 설문분야에 따라 결과가 상이할 수 있어 결과의 신뢰성 및 시계열적 추이분석이 어려워 물산업정책 수립을 위해 활용되는데 한계가 존재하였다. 본연구에서는 기존의 정성적 분석에서 벗어나 정량적인 자료에 근거하여 우리나라의 물산업 기술수준과 시장지배를 동시에 고려하여 분석하였다. 물산업의 기술영향력지수(Cites per Patent)와 시장지배력지수(Patent Family Size)를 기준으로 선도국가와 국내 물산업 기술수준 및 시장영향력을 비교하고 평가하였다. 연구결과의 정책적 활용을 위해 물기술과 물시장의 상이한 분류체계를 물시장 중심으로 재분류하여 물산업 기술경쟁력을 분석하여 제시하였다. 연구결과 우리나라의 국내 기술영향력 중 가장 낮은 분야는 하수도 디지털 분야로 선도국가 대비 30% 수준이었으며 시장지배력분야 또한 하수분야로 7% 수준으로 파악되었다.
