With the increasing interest on K-fashion all over the world, it's the important time to create the items which can express the unique identity of Korea for promoting the globalization of Korean fashion. Accordingly, this study aims to suggest the modern applicability of traditional patterns by designing the bags using the Dancheong patterns(traditional multi-colored decorative painting) which can effectively express Korean images in a variety of shapes and definite visual features and then expand the scope of fashion items. To this end, this study concentrated on expressing the Dancheong patterns to fit to the modern fashion trends by re-interpreting them. The bag was designed using the laser cutting technique, without weaving or digital printing, to imbue the technical emotion and 3D effect to the patterns. In accordance with the analysis results, the features of patterns could be delicately expressed around the shaping and structuring method in terms of the design, and the scope of design for leather goods could be expanded using the laser cutting in technical aspects. For the industrial aspects, it is required to develop differentiated goods expressing the unique emotion of the Korean for globalization of Korean design.

A wide variety of fashion materials focus on good drape property and softness. Among the recently emerging materials, Neoprene that consists of laminated knit on both sides of foamed neoprene sheet seeks a unique appearance that is considerably deviated from the current flow. Diverse processing methods for the newly released material heighten the value in function and beauty among trends of fashion materials by enhancing the appearance, touch and material property. Laser-cutting technique is one of the processing methods that is consistently used in the textile area. This study aimed to find the basic materials for applicability of laser-cutting technique to clothing goods after consideration of the changes in material property and drape shape, and to furthermore enforce different pattern conditions to Neoprene material, one of the newly attractive materials in the fashion area. In this study, we applied laser-cutting technique to Neoprene material sample under different conditions of pattern appearance, size and distance, based on current evaluation and theoretical background of Neoprene material, fashion trend and laser-cutting technique. Drape property can improve and the drape direction could also be controlled by a wide variety of laser-cutting techniques applied to Neoprene materials that have uniquely different appearances from most other textiles. This technique could be applied to the design for diversification of Neoprene clothing goods in the future.

As a cultural feature of, the relics of the Royal Tomb of King Muryeong are suitable design content for applying with sophisticated production and delicate molding laser cutting techniques. The purpose of this study is to develop modern bag designs using relics of the Royal Tomb of King Muryeong of Baekje using laser-cutting techniques. First, the historical background and meaning of Baekje's cultural content were explored. Second, the principle of laser-cutting techniques were explored, laser-cutting techniques applied to modern fashion and bag design were examined, and bag design characteristics were analyzed. Third, based on prior research, the criteria for the development of bag design, from which eight bag design were developed that combine modern popularity and functionality utilizing Baekje cultural content and using laser-cutting techniques to apply the textile design developed by researchers in 2013 (modified to match laser-cutting techniques). The research results show that bag were clutch, tote, shoulder, and mini. Gold, silver, brown, beige, and navy colors were arranged, based on black/white contrast. Cow, lambskin, washed snakeskin, mesh, and Saffiano leather were used. For the pattern-applying technique, this study showed that a new digital technique, which is laser-cutting techniques could be combined with contemporary bag designs. Moreover, a bag design was developed that has a modern sense and functionality as well as Korean formativeness, which is significant.

This paper show the 2kW fiber laser cutting properties of SS400. The study was comparison of traditional 4kW $CO_2$ Laser cutting and 2kW Fiber laser cutting characteristics for the application of Industrial 2D Laser Cutting Machine. The laser used in this investigation was an IPG YLU-2000 multi-mode Ytterbium Fiber machine with a maximum power of 2000W and a wave length of 1070 nm. The laser was used in its Continuous Wave (CW) mode with an approximately top hat beam intensity distribution. Fiber laser high quality cuts at a large range of speeds (ranging from 2000 to 3800 mm/min) which has been obtained for the 2.3mm Sheet of SS400. 2kW power Fiber laser cut was able to max. 20mm sheets of SS400 (speed range from 650 to 850 mm/min). Fiber laser cutting used in conventional hole nozzle could cut 12mm SS400 but used in special dual cutting nozzle could cut 20mm SS400.

LASOX is a cutting technology used to dismantle nuclear power plants. The core component of the laser-assisted oxygen hybrid cutting process is the supersonic nozzle. To design optimized supersonic nozzles, an experimental design was established and computational fluid dynamics was used to analyze the supersonic nozzles. The main factors affecting the supersonic nozzle performance were identified using Minitab. Further, the correlations and interactions between the main factors of the supersonic nozzle design were analyzed. The fluid analysis results were examined for the major factors and standardized response variables as well as main effects to ensure suitability of the supersonic nozzle design for the laser-assisted oxygen cutting process.

지구과학 분야에서 가장 어렵게 느껴지는 내용인 천문분야는 다른 과학 분야와 달리 탐구 대상이 천체들이 먼거리에 있고, 쉽게 관측하기 어려우며, 실험실에서 동일실험과 반복 실험이 불가능하여, 추상적이고 직접 관측하기 어려운 개념에 관한 연구들이 많다. 따라서 이 연구에서는 레이저 커팅기를 사용해 지구과학교과 중 별자리를 구성하는 별들의 상대적 거리를 수학적으로 계산하는 과정과 고등학교 물리교과 중 LED 광원의 원리를 알고 LED 모듈을 제작하여 최종적으로 아름답고 과학적으로 가치가 있는 입체 별자리 교구를 제작하는 형태의 STEAM 교육 프로그램을 개발하고 시범학교 적용을 하였다. 이에 지능정보화 사회에 발맞춰 천문학 지식을 창의 교육의 형태로 교육하는 새로운 교육법을 실현한 연구결과들을 발표하고자 한다. 또한 개발한 프로그램의 효과성을 검증하기 위해 STEAM 관련 태도 검사와 논리적 사고력 검사 및 만족도 검사를 실시하였다. 연구결과 개발된 프로그램이 STEAM 태도 검사와 논리적 사고력에 효과가 있는 것으로 나타났으며, 천문수업에 대한 학생들의 인식은 긍정적이었다. 따라서 후속 연구에서는 다양한 학년 및 위계에 맞는 프로그램의 개발과 다양한 지역 등의 현장 적용을 통한 연구가 진행되어야 할 것으로 판단된다.
