Tartan, the woven, checked, and wool textile considered by many to be originally from Scotland, has in fact been in use in a range of forms across numerous cultures and during various historical periods. The characteristic checked feature is due to the assembly of different coloured threads in both warp and weft directions which intersect at 90 degrees in a combination known as a sett. For well over one hundred years, different setts and thus different colour combinations have been associated closely with different geographical regions within Scotland, as well as different clans or families. Tartan-type textiles have reached popularity at various times and those have often been a predicted fashion trend suggested, for example, by contributors to fashion gatherings such as Premier Vision in Paris. Often proposed designs are best considered based on tartan combinations rather than simple reproductions. Promotional terms such as “patched checks” or “textured checks” have been common, and often these have been derived from tartan-type constructions. This paper explores novel pattern design methods by identifying the underlying grid structures and proportions exhibited by various well-known tartan setts. The possibility of pattern development from tartan grids and their manipulations is thus the focus of attention. An insight into the methodology associated with the production of original pattern designs is thus provided.

The electromagnetic interference(EMI) shielding sheet of grid pattern for the wireless charger has been designed by using grid pattern metal sheet, PET & DST stacking and laminating technology. For this purpose, the twisting protection and the bubbling prevention device, the automatic position adjustment controller, the visual sensors and the motor actuator for controller, the EMI shielding sheet cutting device and the main control system have been developed for manufacturing the apparatus. As the study result, the development on manufacturing the equipment and shielding sheet of the EMI shielding sheet of grid pattern for the wireless charger having the lamination productivity of 27.4m/min exceeded the target of 8m/min in this study. In addition, the magnetic induction and the applicable shielding sheet were prepared in the magnetic resonance system, all of the two wireless charging system. The power with a band of average 6.87MHz of shielding sheet was greater than the target of 30dB to 32.57dB. The available frequency with a band of average 7.95MHz the target was exceeded by a 7.00MHz.

The grid pattern electromagnetic interference(EMI) shielding sheet for the wireless charger has been designed using grid pattern metal sheet, PET & DST stacking and laminating technology. Also, an automatic manufacturing system of the grid pattern EMI shielding sheet for the wireless charger is developed. This metal sheet with grid pattern is an effective shield against EMI that can not shield completely by existing single metal sheet. And the developed automatic manufacturing system having a laminated productivity exceeds the 8m/min can stack and lamination thin metal sheets without any wrinkles.

본 연구는 최근 비용의 문제로 인해 기획과는 무관하게 디자인이 획일화된 반응형 웹이 증가함에 따라 해당 웹 사이트의 목적을 체계화한 웹 서비스 유형에 따른 그리드 패턴 동향을 도출, 완성도 있는 반응형 웹을 보다 효율적으로 개발하는 데에 목적이 있다. 이를 위하여 1차로 그리드 시스템 및 반응형 웹의 5개 그리드 패턴과 서비스산업 분류체계에 대하여 이론 적으로 고찰한 후 이를 토대로 웹 서비스 유형을 체계화하였다. 2차로 반응형 웹과 적응형 웹의 비중을 알아볼 목적으로 웹 어워드 코리아(I-award)의 2016, 2017, 2018년도 910개 수상작을 분석한 결과 반응형 웹의 비중은 약 40%로 파악되었으며, 356개 반응형 웹의 그리드 패턴 비중을 분석한 결과 Mostly Fluid 62.9%, Column Drop 21.9%, Tiny Tweaks 8.4%, Layout shifter 5.3%, Off Canvas 1.9% 순으로 높은 비중을 차지했다. 또한 개발 연도에 따른 그리드 패턴의 경우 유의미한 동향이 나타나지 않았으나 웹 서비스 유형에 따른 그리드 패턴의 경우 유의미한 동향을 도출하였다. 디자이너 및 개발자는 본 연구의 결과를 참고하여 개발하고자 하는 웹 사이트의 목적을 웹 서비스 유형에 도입하여 그리드 패턴 비중을 파악, 더욱 효율적인 개발이 가능할 것으로 기대한다.
