특허-상표 연계 비즈니스 인텔리전스를 위한 텍스트 분석 기반의 비즈니스 영역 식별

This study presents a novel approach for identifying new business opportunities by analyzing the linkage between patents and trademarks leveraging text analytics. Initially, we utilize topic modeling to analyze the descriptions of goods and services in trademarks, with a particular focus on trademarks that do not share similar group codes. Using the Latent Dirichlet Allocation (LDA) model, the descriptions in the trademarks are segmented into multiple business groups based on similarities. Subsequently, we define business areas by measuring their similarity to the industry classifications represented by the Standard Industrial Classification (SIC) system. To this end, we propose a novel weighted cosine similarity. Leveraging the proposed similarity, we align each patent with one of the predefined business groups extracted from the trademark data. Based on this approach, we can identify business areas closely related to the technological capabilities of tech-based firms. In the case study, we showed that business areas are identified through the alignment between the customized goods and service groups and SIC from trademark data of global technology-based firms.

우리는 디지털 디자인의 발전을 위한 역동적 특성으로서 효과적인 디지털 디자인 프로세스의 방법에 대한 연구가 필요한 시점에 와 있다. 이 연구는 스마트 재료 및 기술에 대한 디지털 디자인 교육과 디지털 디자인의 새로운 이해를 모색하는 연구이다. 스마트 재료와 기술을 분석하여 각 재료요소의 조합특성을 파악하였고 디지털 미디어의 활용과 어떻게 효과적으로 디지털 디자인 스튜디오를 운영할 것인가를 개념적 특성과 재료의 특성, 그리고 창의성 증진을 위한 디자인 원리에서 그 체계적인 해결방법을 찾으려고 하였다. 파라메트릭, 위상기하학적, 기하학적, 생성적 특성을 갖는 디지털 디자인은 형성, 생성, 성능 이라는 핵심개념으로 새로운 디자인을 위한 동기를 부여하고 있다. 스마트 재료와 기술의 공간 적용은 인간을 위한 웰빙, Eco, 안전과 건강, 디자인의 융합을 필요로 하고 있다. 이 연구는 스마트 재료와 기술이 디지털 디자인과 관련하여 어떻게 교육되어야 하는지에 대한 교육모델을 제안하였으며 새로운 경향의 디지털 디자인 교육 연구의 단초가 되고 교육적 경쟁력을 높이는데 기여할 것이다. We are faced with the time when needs the study that focuses on methods of digital design process of a dynamic property through developing an effective digital design. In response to the need, this paper explores new understanding of designing in relation to digital design media and digital design pedagogy. This study tries to find the property of materials analyzing smart materials and technologies, a way to utilize digital media and design and finally a design principles for increasing creativity. Digital design has a potential to make a new designing, for it has formation, generation and performance which have the parametric, topological, geometrical property. The applied the space of smart materials and technologies by the designer needs the coordinated approach for Well-being, Eco, Safe and health and the convergence of design for human. When the smart materials and technologies are applied, well-being, eco, safeness and health and the convergence of design for humans have to be considered. This study proposes an educational model for digital designing using the smart materials and technology and hopes to be a digital design pedagogy that responds to present’s new needs.

PVDF 압전막을 이용한 초고주파 집속 초음파 트랜스듀서의 제작 및 특성 평가
윤주호,오정환,김정순,김무준,하강렬,Yoon, Ju-Ho,Oh, Jung-Hwan,Kim, Jung-Soon,Kim, Moo-Joon,Ha, Kang-Lyeol 한국음향학회 2011 韓國音響學會誌 Vol.30 No.4
In order to obtain high resolution images, a focusing ultrasonic transducer operated in very high frequency (VHF) range was fabricated and its characteristics were evaluated. A 9-${\mu}m$ thick PVDF film with only one metalized surface for electric ground was adhered to a CCP (Copper-clad polyimide) film by using epoxy. It was pressed by a metal ball to form a concave surface and its rear side was filled with the epoxy. The radius of curvature and the f-number of the fabricated transducer are 7.5 mm and 1.7, respectively. The pulse-echo measurement results from a target located at the focal point showed that the frequency bandwidth was 35.0 MHz and the insertion loss near the peak frequency of approximately 40 MHz was about 60 dB. Those values agreed well with the simulation results by the KLM equivalent circuit analysis including the effect of the epoxy bonding layer. When the image of thin copper lines by the 35 MHz transducer of the UBM (Ultrasonic Backscattering Microscope) system was compared with the image by the transducer fabricated in this study, the fabricated transducer was observed that the axial resolution was improved although the lateral resolution was degraded. 높은 분해능의 영상을 얻는데 사용하기 위하여 초고주파 대역에서 동작하는 집속 초음파 트랜스듀서를 제작하고 그 특성을 평가하였다. 그 트랜스듀서는 한쪽 면에만 접지용 전극이 있는 두께 9 ${\mu}m$의 PVDF 압전막의 다른 쪽 면에 CCP (Copper Clad Polyimide)막을 에폭시로 접착한 후, 금속구로 압착함에 의해 구각형을 형성시키고, 그 뒷면에 에폭시를 채워 몰딩 시키는 방법에 의해 만들어졌다. 제작된 곡률반경 7.5 mm, f-number 1.7의 트랜스듀서는 초점에 있는 표적에 대한 펄스에 코 측정결과 35.0 MHz의 대역폭을 가지며, 약 40 MHz인 피크주파수 부근에서의 삽입손실은 약 60 dB 을 나타내었는데, 그 측정결과는 에폭시 접착층의 두께를 고려한 KLM 등가회로 해석에 의한 시뮬레이션 결과와 유사한 것이었다. 나아가, 그 트랜스듀서에 의해 얻어진 가는 구리선 표적에 대한 영상을 35 MHz 트랜스듀서를 장착한 UBM (Ultrasonic Backscattering Microscope) 장치에 의한 영상과 비교한 결과, 측방향 분해능은 떨어지나 축방향 분해능은 다소 향상됨을 알 수 있었다.

Objectives : The Purpose of this study was to identify anti-tumor effects of Curcuma longa L. on some kinds of cancer cells through molecular biologic methods. Materials & Methods : We used 4 kinds of cancer cell lines such as glioma cells(A172), cervical cancer cells(HeLa), Prostate cancer cells(PC3), lung cancer cells(A549). We injected the boiled extract of Curcuma longa L. $5{\mu}g,\;10{\mu}g$ to culture media(ml) for 24 hours. We measured the cytotoxic effect on 4 kinds of cancer cells through trypan blue exclusion test and the suppressive effect on viability of 4 kinds of cancer cells via MTT assay. We measured the change of mitochondria membrane potential via flow cytometry. The quantitative RT-PCR was used to examine the effect on the revelation of Bcl-2 and Bax which genes are related to apoptosis. We examined the effect on the revelation of Bcl-2 protein and Bax protein by western blot analysis. Results: 1. Extract of Curcuma longa L. showed significant cytotoxic effect on A172, HeLa, PC3 compared to the control group with density dependent manner. 2. Extract of Curcuma longs L. showed significant suppressive effect on viability of A172, HeLa, PC3 compared to the control group with density dependent manner. 3. Curcuma longs L. induced apoptosis by decreasing the membrane potential of mitochondria in A172, HeLa, PC3. 4. In the test about the revelation of genes related to apoptosis, the revelation of Bcl-2 decreased and the revelation of Bax increased in A172. HeLa, PC3 treated with Curcuma longa L. with density dependent manner. 5. In the test about the revelation of protein related to apoptosis, the protein levels of Bcl-2 decreased and the protein levels of Bax increased in A172, HeLa, PC3 treated with Curcuma longa L.
