This paper deals with technology relevance analysis, which measures technological dependency between needs technology and its component technology as well as between needs technologies. The two-round survey was carried out: In the first round, a wide range of needs technologies in construction and building industry were identified and classified to meet a variety of social needs which were anticipated in the near future of Korea. In the second, relevance between needs technology and its component technologies was checked by some 120 experts. Based on the survey results, the individual relevances among needs technologies were computed. Finally the ranking of needs technologies in construction industry was set according to the degree of technology relevance. This relevance is to be used as one of criteria for the selection of national R&D projects which the Ministry of Construction and Transportation plans to promote in the next five years.

Relevance has a long history of scholarly investigation and discussion in information science. One of its notable concepts is that of 'user-based' relevance. The purpose of this study is to examine how users construct their perspective on the concept of relevance; to analyze what the constituent elements (facets) of relevance are, in terms of core-periphery status; and to compare the difference of constructions of two groups of users (information users vs. information professionals) as applied with a social representations theory perspective. Data were collected from 244 information users and 123 information professionals through use of a free word association method. Three methods were employed to analyze data: (1) content analysis was used to elicit 26 categories (facets) of the concept of relevance; (2) structural analysis of social representations was used to determine the core-periphery status of those facets in terms of coreness, sum of similarity, and weighted frequency; and, (3) maximum tree analysis was used to present and compare the differences between the two groups. Elicited categories in this study overlap with the ones from previous relevance studies, while the findings of a core-periphery analysis show that Topicality, User-needs, Reliability/Credibility, and Importance are configured as core concepts for the information user group, while Topicality, User-needs, Reliability/Credibility, and Currency are core concepts for the information professional group. Differences between the social representations of relevance revealed that Topicality was similar to User-needs and to Importance. Author is closely related to Title while Reliability/Credibility is linked with Currency. Easiness/Clarity is similar to Accuracy. Overall, information users and professionals function with a similar social collective of shared meanings for the concept of relevance. The overall findings identify the core and periphery concepts of relevance and their relationships in terms of coreness, similarity, and weighted frequency.

혁신형 중소기업 기술금융의 지속적인 확대와 발전을 위해서 기술금융 지원사업의 적절성이 요구된다. 본 연구에서 기술금융 수혜기업의 선정이 사업 목적과 취지에 적합한지 여부를 실증 분석하였다. 기술금융 여신이 발생될 확률은 기술력등급이 높을수록, 영업이익률이 높을수록 증가하는 것으로 나타났다. 반면에 자본금과 업력이 증가할수록 기술금융 여신 승인이 발생될 확률은 점진적으로 감소하는 것으로 나타났다. 로지스틱 분석결과 기술력 등급과 기업의 주요 특성이 기술금융 수혜기업 선정에 유의한 영향을 미친 것으로 나타났다. 그러나 모형의 적합성인 정분류율이 높지 않기 때문에, 기술금융의 적절성을 높이기 위한 개선을 제안하였다. 그리고 회귀분석 결과 대출금 규모와 기술력 등급사이에 연관성은 유의하지 않게 나타났다. 본 연구결과와 제안은 기술금융 결정의 적절성과 신뢰성을 확보하는 데 기여할 것이다.

In this paper, a novel image projection technique for face recognition application is proposed which is based on linear discriminant analysis (LDA) combined with the relevance-weighted (RW) method. The projection is performed through 2-directional and 2-dimensional LDA, or $(2D)^2$LDA, which simultaneously works in row and column directions to solve the small sample size problem. Moreover, a weighted discriminant hyperplane is used in the between-class scatter matrix, and an RW method is used in the within-class scatter matrix to weigh the information to resolve confusable data in these classes. This technique is called the relevance-weighted $(2D)^2$LDA, or RW$(2D)^2$LDA, which is used for a more accurate discriminant decision than that produced by the conventional LDA or 2DLDA. The proposed technique has been successfully tested on four face databases. Experimental results indicate that the proposed RW$(2D)^2$LDA algorithm is more computationally efficient than the conventional algorithms because it has fewer features and faster times. It can also improve performance and has a maximum recognition rate of over 97%.

R&D는 산업과 제품의 특성에 따라 그 중요도가 다르며, 제품의 고부가가치를 중요시하는 첨단산업에 있어서 R&D의 중요성이 크다. 그런데 첨단산업의 기업은 전통적인 상장기업에 비해 재무변수의 기업가치 설명력이 상대적으로 낮게 나타나는데 그 원인은 재무제표에 기록되지 않은 무형자산 때문인 것으로 추정된다. 이에 본 연구의 목적은 코스닥기업을 첨단산업과 비첨단산업으로 나누어 무형자산성 지출의 가치관련성을 분석하는 것이다. 무형자산성 지출은 연구개발비, 교육훈련비, 광고선전비로 측정하였다. 분석 결과 첫째, 첨단산업에서는 연구개발비가 기업가치에 양(+)의 유의한 영향을 미치는 것으로 나타났고 교육훈련비는 기업가치에 음(-)의 유의한 영향을 미치는 것으로 나타났다. 비첨단산업에 있어서는 교육훈련비가 기업가치에 양(+)의 유의한 영향을 미치는 것으로 나타났다. 첨단산업과 비첨단산업 모두 광고선전비는 유의한 영향을 미치지 않는 것으로 나타났다. 둘째, 대형회계법인의 감사품질은 첨단산업의 연구개발비의 가치관련성을 더욱 증가시키고 비첨단산업의 교육훈련비의 가치관련성을 증가시키는 역할을 하는 것으로 나타났다. 이러한 연구결과는 투자자들이 전자, 통신, 제약, 정밀기계와 같은 첨단산업군의 연구개발비 투자에 대해 비첨단산업군의 연구개발비 투자와 비교해서 더 가치 있는 투자로 평가하는 것으로 해석할 수 있다. 본 연구의 연구결과는 첨단산업과 비첨단산업의 경영자의 무형자산성 투자의 의사결정에 있어서 유익한 참고가 될 수 있을 것으로 기대한다.

The purpose of the study was to analyze consumers' perceptions of gamification. Based on the analyzed data, we would like to provide data by systematically organizing the concept, game elements, and mechanisms of gamification. Recently, gamification can be easily found around medical care, corporate marketing, and education. This study collected keywords from social media portal sites Naver, Daum, and Google from 2018 to 2023 using TEXTOM, a social media analysis tool. In this study, data were analyzed using text mining, semantic network analysis, and CONCOR analysis methods. Based on the collected data, we looked at the relevance and clusters related to gamification. The clusters were divided into a total of four clusters: 'Awareness of Gamification', 'Gamification Program', 'Future Technology of Gamification', and 'Use of Gamification'. Through social media analysis, we want to investigate and identify consumers' perceptions of gamification use, and check market and consumer perceptions to make up for the shortcomings. Through this, we intend to develop a plan to utilize gamification.
