The feeling that is evoked when products are handled has become increasingly important in the design of products primarily used by humans. In the traditional product design process, prototypes are built several times in order to evaluate the feeling evoked during use. However, these design processes can be optimized by adopting a haptic simulator that can serve as a prototype. The design method based on the use of the haptic simulator is called haptics-aided design (HAD), which is the main subject of this paper. Here, a new HAD method that can be effectively used to design a custom-made chair is proposed. A haptic simulator, which is composed of a haptic chair and an intuitive graphical user interface, was developed. The simulator can adjust the impedance of the backrest and seat pan of a chair in real time. The haptic chair was used instead of real prototypes in order to evaluate the comfort of the initially designed seat pan and backrest on the basis of their stiffness and damping values. It was shown that the HAD method can be effectively used to design a custom-made chair and can be extended to other product design processes.

Bolus is used in radiation therapy to prescribe an even dose to the tumor when the skin surface is inclined or has irregularities. At this time, the dose to the skin surface increases. Due to the patient's unique body structure and irregular skin, voids may occur between the bolus and the skin, which may reduce the accuracy of treatment. Therefore, in this study, the existing bolus and the self-produced bolus through 3D printing were applied to the nasal area, and the difference between the surface dose after treatment plan and the dose directly measured with an Optically Stimulated luminescence(OSL) dosimeter was compared to the existing bolus. The bolus rate was 97%, PLA 100.33%, ePETELA 75A 100.53%, and ePETELA 85A 100.36%. It was confirmed that there was little error in the measurement values and treatment plan values for each material. In addition, compared to when applying a conventional bolus, a difference of -3% to +0.5% for a 3D printed bolus can be confirmed, so a customized bolus produced through 3D printing can complement the shortcomings of the existing bolus. It is believed that there will be.

언제 어디서든 한 손으로 미디어 콘텐츠를 소비할 수 있게 해주는 모바일 기기들이 기존 전통적 미디어 콘텐츠 단말기였던 TV나 데스크톱 PC들을 대체하게 되면서 세로형 영상 콘텐츠에 대한 수요가 나날이 높아져 가고 있다. 이와 더불어 모바일 단말기 제조사들은 서로 간의 경쟁에서 앞서기 위해 제품 차별화 전략을 수립하고 모바일 사용자들의 요구 사항을 세세하게 맞추기 위한 결과, 저마다 다른 디스플레이 해상도 규격을 가진 모바일 기기들이 생산되고 있는 상황이다. 이에 미디어 콘텐츠 제작자들은 기존 가로형 영상 콘텐츠와 더불어 새롭게 요구되는 세로형 영상 콘텐츠들을 저마다 다른 해상도 규격에 맞추는데 많은 시간과 비용을 투자하고 있다. 더 나아가 모바일 단말기 해상도 규격과 맞지 않는 영상 콘텐츠를 시청하게 될 경우, 모바일 사용자 입장에서는 디스플레이 전체 영역을 뷰포트로 잡을 수 없어 시청 만족도가 떨어질 수 있다. 이에 본 논문은 한 번의 콘텐츠 제작을 통해서도 추가 비용 없이 다양한 디스플레이 규격을 가진 단말기들에 대해 맞춤형 콘텐츠 서비스 제공을 가능하게 하여 미디어 콘텐츠 소비자들에게 충분한 시청 몰입감을 제공해줄 수 있는 단말 적응적 미디어 화면비 변환 시스템을 제안한다. 단말 적응적 미디어 화면비 변환 시스템은 딥러닝 네트워크 모델과 이미지 관련 라이브러리를 기반으로 하여 설계한 시스템이며, 사용자가 시청하기 원하는 영역을 판단하고, 사용자가 원하는 뷰포트 종횡비에 따라 해당 영역을 잘라내어 사용자가 원하는 세로형 영상 콘텐츠를 제공해준다.

While the second and the third industrial revolutions made it possible a few standardized designs to be extracted and produced in large quantities, the recent development of the 3D printing technology allowed many individuals to reflect their unique personal characteristics on their creative works and produce them in large quantities-i.e., personally customized designs and mass production of various designs. However, for the customized designs and the mass production of various designs through the 3D printing technology, the individuals should use a 3D modeling software and the supporting features of the software can significantly affect the type and shape of a creative work. In this study, we surveyed the individuals who design the creative works using 3D printers about the type of software that they use and the type of creative works that they design using the software, to propose a possible direction of new software that supports their activities. To do this, we first surveyed sixty members of the OpenCreators, which is the largest 3D printing creator community in South Korea, about the 3D modelling Software that they use for their 3D printing creations, the best 3D modelling software for the 3D printing, and the type of frequently printing creation using the best 3D modelling software. We then analysed the response results. As a result, we found that most of 3D printing creators in South Korea use Rhino and 123D Design. More specifically, the Rhino was being widely used by the people in the 3D printing industry to print prototypes, samples, and mock-ups, while the 123D Design was being mainly used for general purposes such as educational tools, accessories, and home interior accessories. Therefore, we believe it is necessary to develop the software in two separated categories, i.e. for the business, like the Rhino, and for the beginners, and educational and personal purposes, like the 123D Design. Finally, we stressed and proposed the necessity to support individual creators by developing an industry-specific 3D modeling software.

Purpose: Unpredictable shrinkage of zirconia during sintering process causes discrepancy. Therefore, there have been attempts to reduce discrepancy by milling zirconia after sintering. However, due to the hardness of sintered zirconia, milling takes longer time, causes damage to the machine and causes chip formation. With customized zirconia block using the mean dimension of prepared natural dentition, it is expected to overcome these shortcomings. Materials and methods: The mean dimension of prepared natural dentition was analyzed as STL file after scanning of prepared teeth treated at SNUDH. The transverse, frontal and sagittal planes were set using Mimics and Photoshop. 3D volume was projected on each plane, and the outer line was measured through external tangent line, and the inner line was measured through inflection point of tangent line. Results: The mean height of prepared incisal (N = 57) is $6.60{\pm}1.05mm$, mesiodistal length is $2.98{\pm}0.73mm$, buccolingual length is $2.04{\pm}0.73mm$. The mean height of prepared premolar (N = 15) is $5.37{\pm}1.49mm$, mesiodistal length is $4.10{\pm}1.78mm$, buccolingual length is $5.86{\pm}1.55mm$. And the mean height of prepared molar (N = 13) is $5.11{\pm}1.29mm$, mesiodistal length is $6.80{\pm}1.18mm$, buccolingual length is $7.34{\pm}1.40mm$. Conclusion: Using the mean dimension of prepared natural dentition, it is expected to be able to fabricate customized zirconia block.
