개방형 혁신활동의 외부 협력파트너 유형과 혁신성과 간 관계: 기업규모와 산업유형의 조절효과를 중심으로
이다영(DaYoung Lee),박유안(Yuan Park),조근태(KeunTae Cho) 한국기술혁신학회 2021 기술혁신학회지 Vol.24 No.6
본 연구의 목적은 개방형 혁신활동의 외부 협력파트너 유형이 혁신성과에 미치는 차별적 영향과 기업규모 및 산업유형의 조절효과를 규명하는 것이다. 이를 위하여 선행연구를 기반으로 가설을 설정하였고, 2018년 한국기업혁신조사자료를 이용하여, 서비스업 3,500개 사, 제조업 3,500개 사를 대상으로, 로지스틱 회귀분석을 통해 검정하였다. 분석결과, 기업의 혁신성과 외부협력파트너 유형과의 협력 관계에서는 기업, 공공연구기관과는 유의하였고 조절변수 중, 기업규모는 외부 협력파트너 유형 중, 공공연구기관과의 협력에서 혁신성과에 양(+)의 조절효과가 나타났으며, 산업유형은 기업과의 협력에서 양(+)의 조절효과가 있는 것으로 나타났다. 본 연구는 개방형 혁신 진행 시, 외부 협력파트너 유형별 협력이 혁신성과에 미치는 영향과 더불어 조절변수로 기업규모와 산업유형을 활용한 점에서 그 의의가 있다. 외부와의 기술협력을 진행하고자 하는 기업들에게 적절한 협력파트너 선택이 중요하다는 것을 시사하고 있다. The purpose of this study is to investigate the discriminatory effect of external cooperative partner types of open innovation activities on innovation performance and the moderating effect of corporate size and industry type. To this end, hypotheses were established based on previous studies, and 3,500 service companies and 3,500 manufacturing companies were tested through logistic regression analysis using data from the 2018 Korea Enterprise Innovation Survey. As a result of the analysis, it was found that the cooperation relationship between corporate innovation and external cooperation partner type was significant with companies and public research institutes, and among the control variables, the company size showed a positive (+) control effect on innovation performance. This study is meaningful in that cooperation by type of external cooperative partner has an effect on innovation performance during open innovation, as well as the use of company size and industry type as control variables. This suggests that it is important for companies that want to proceed with technical cooperation with the outside world to select an appropriate cooperative partner.

분광측색계, 색차계의 색 수치 값을 이용한 타이타늄 산화막의 두께 정량화
이다영(Dayoung Lee),한아영(Ayoung Han),하동흔(Dongheun Ha),유현석(Hyeonseok Yoo),김훈식(Hunsik Kim),정나겸(Nagyeom Jung),장관섭(Kwanseop Jang),최진섭(Jinsub Choi) 한국표면공학회 2018 한국표면공학회지 Vol.51 No.3
The anodic TiO₂ layers which are prepared in various anodization conditions exhibit their specific color depending on the thickness of TiO₂. In this study, the relationship between the color of TiO₂ layer, which is grown by PEO (Plasma electrolytic oxidation), and the thickness of the TiO₂ layer is investigated. To evaluate the color change of the TiO₂ layer, the value of color (dE<SUP>*</SUP>ab) is measured and calculated by spectrophotometer and chromameter. As a result, it is found that dE<SUP>*</SUP>ab values and thickness of TiO₂ layers form a linear relationship with meaningful formular. This formula can be helpful to quantify the thickness of the TiO₂ layer by the numerical dE<SUP>*</SUP>ab values. In this process, the spectrophotometer shows more precise results than the chromameter dose. If fluoride ions (F-) are included in the electrolyte, it will affect the dE<SUP>*</SUP>ab values of the TiO₂. layer. This is against the propensity, which is analyzed by XRD (X-ray diffraction) and XPS (X-ray photoelectron spectroscopy). It is important that the formular suggested in this study provides other metals which can be also anodized with the possibility of quantifying the thickness of the TiO₂ layer by the dE<SUP>*</SUP>ab values.

While advertisement design education sheds light on idea expression method and technique of expression, the evaluation of how effectively advertisement expressions deliver advertisement contents is considered less important, and remains considerably subjective and ambiguous if any. To arouse their curiosity, the education requires students to practice to treat signification as metaphor. It is problematic that their arbitrary interpretation of signification is evaluated without any objective indicator. This study aims to develop a tool for students in an advertisement design class to review how effectively the advertisement design presents its signification in the middle stage through a semiotic approach by themselves. To that end, the paper discussed semiotic approaches in existing studies, conducted a case study on award-winning works of public service advertisement in printed media, and then proposed a framework to visibly check out the association between the quantity of signs and the ultimate message of the advertisement and that between isotope and the message. The case study found that the quantity of signs and their association with the message are related with the quantity of total information in the advertisement and necessary core information and the difference between the quantity of signs and their association confirms their uncertainty. The quantity of isotope is related with overlapped meanings of signs. A high degree of overlapping makes the message of the advertisement clearer, but the message is exposed too easily to make the advertisement less interesting.

생물학적 순차 데이터에 기반한 소리화 작품 창작에 관한 연구
이다영(Dayoung Lee),김주섭(Jusub Kim) 한국디지털콘텐츠학회 2024 한국디지털콘텐츠학회논문지 Vol.25 No.2
Sonification is the process of converting data into sound; it serves a practical function in helping to intuitively understand data by converting numeric or textual data into audible sound, and an artistic function in making everyday data unfamiliar and interesting. Sonification has largely focused on sequential data owing to their similarity to sound, with a naturally temporal sequence. This study explores how the public perceive the sonification of biological sequential data, especially Nucleic Acid Sequence, through three examples of the authors sonification art works: 〈The Sound of Plants〉,〈ViViD〉, and〈Ŏdŭme〉. A total of 106 visitors in their 10s to 40s participated in a survey and interviews to evaluate exhibitions quantitatively and qualitatively. The findings show that sonification can help people understand data and generate interest in the subject by making the subject unfamiliar. Moreover, the sonification of biological science data as an artistic practice can generate new and meaningful results.
