Using the dynamic explicit program NET3D, oblique impact between long rod penetrator and metallic plate was analyzed. Compared with an experiment and AUTODYN-3D analysis result, the accuracy of NET3D program was examined. It was proved that NET3D program could analyze comparatively exactly oblique impact phenomenon between long rod penetrator and metallic plate. The final deformed configuration of penetrator predicted by NET3D program was more close to experimental result than commercial program AUTODYN-3D. But, in order to increase the reliability of NET3D program in the simulation of tensile fracture phenomenon, the additional research is required.

시추데이터는 작업자가 작업현장에서 안전하게 공사를 수행할 수 있도록 제공하는 지반정보로, 현재 시추데이터를 3차원 데이터로 만들어서 3차원 형태의 이미지로 볼 수 있도록 지원하고 있다. 지반정보의 3차원 가시화를 이용하여 다양한 프로그램을 개발하는 국내의 기업들은 지반 정보의 3차원 가시화를 위해 C Tech Development Corporation에서 개발한 MVS 프로그램을 사용하고 있다. 그러나 MVS 프로그램은 유료 프로그램이고 국내에서 개발하는 3차원 관련 프로그램에서 사용하기에는 어려움이 있다. 본 논문에서는 파이썬의 Gempy 오프 소스를 이용하여 군집화된 시추정보로 부터 3차원 지층모델을 생성할 수 있도록 MVS를 대체할 수 있는 라이브러리를 개발하고자 한다. 3차원 지층모델 프로그램은 각 지층별 포인트 데이터를 생성하고 보간을 통해서 지층별 표면을 생성한다. 그리고 각 지층별 표면을 합하여 3차원 지층모델 프로그램을 완성한다. 고양 지역의 시추데이터로부터 MVS 프로그램과 제안하는 프로그램으로 3차원 모형을 생성하여 비교하였을 때 큰 차이가 없음을 확인하였다.

This paper deals with the development and application of a 3D printing education program implemented to cultivate creative fusion-type talents required by the 4th Industrial Revolution. Specifically, the entire process developed by applying the ADDIE program development model, from 3D modeling to post-processing of printed materials, was performed individually and for each team for about 200 second-year college students for two weeks. Through this program, students develop the basic ability to apply 3D printing to the learning curriculum, the ability to solve problems through cooperative interactions between team members, and convergence thinking ability by collaborating within the team by students from various major fields. They are proved by analyzing an education satisfaction survey conducted after application of the program. In conclusion, the program of this paper presents a methodology for effective 3D printing education in universities.

This paper is to model a 3D-shape product applying mathematically the data acquired from a 3D scanner and using an Automatic Design Program. The research studied in the reverse engineering up to now has been developed continuously and surprisingly. However, forming 3D-shape solid models in CAE and CAM, based on the research, the study leaves much to be desired. Especially, analyses and studies reverse-designing automatically using measured data after manufacturing. Consequently, we are going to acquire geometric data using an 3D scanner in this study with which we will open a new field of reverse engineering by a program whic hcan design a 3D-shape solid model in a CAD-based program automatically.

The purpose of this thesis is to compare the efficiency of 3D digital design technology with traditional hand-drawn designs of a transformable dress for a small wedding. After reviewing the literature, this empirical study analyzed the tendencies of small wedding dress design, concluding that a transformable dress for a small wedding consists of a bodice, skirt, and outer skirt or gown with train, each of which has five possible designs, resulting in 15 virtual items within the 3D program. The 3D program provides the benefit of easy design development as well as reduced costs and design time. Specifically, the random combination of 15 items with layers in the 3D program produced 150 different styles in 5 hours, while hand-drawing 150 dresses took 50 hours. Moreover, the 3D program does not need any material, but 150 physical drawings required a sketchbook, pencil, eraser, and marker, total cost 31,100 won. Additionally, the 3D whole-body scan helps the bride decide which design she prefers through virtual try-ons. Eventually, the 3D program could help a bride decide what she prefers and produce it with virtual simulation, resulting in reduced time and costs.

The study aimed to analyze the functional differences in 3D virtual garment programs and compare body scan data with the corresponding 3D virtual models. We selected 3D virtual garment programs, formed virtual models in a representative size for high-school male cyclists, and analyzed them using the Design-X program. The results were as follows. In the 3D virtual garment programs, the anthropometric items for virtual model forming differed significantly from the standard anthropometric items suggested by Size Korea. Comparing the lower body scan data and virtual models formed by the 3D virtual garment programs, the biggest difference was in the shapes of the waist and hips, i.e., the flatness values of the waist and hips were different for each program in the cross-section view. In the lower body, a data-input-based program was needed for changing the exact measurement position of the waist circumference and hips' shape in detail. If a 3D virtual garment program provides functions for the virtual model's joint angle input and free motion transformation, it is expected to be widely used in the sportswear industry.

This study introduces the development and application of instructional materials for a micro-UAV (unmanned aerial vehicle) design and manufacturing program in university education for freshman/sophomore students. The ADDIE methodology was applied to the development of educational materials, which consist of 15 lessons including the aircraft design theory, 3D CAD modeling, 3D printing production, and UAV flight control. The validity of the program was evaluated with 8 expert panels. A total of 82 participants from engineering and social science grouped the 16 teams for the creative UAV wing design and cooperative interactions. The results of overall program satisfaction survey was measured highly as the average 4.54 (out of 5), so that the students were content with the professional engineering knowledge, 3D digital tools, and the opportunity to design and manufacture airplanes on their own. In conclusion, it can be confirmed that the developed program is effective for UAV education for junior level college student.

To develop reliable 3D face recognition system, many researchers also have focused on 3D face data acquisition system. Previous many 3D face acquisition systems use visible patterns to solve corresponding problem, and this pattern made anyone who wants to be verified uncomfortable. In this paper, we propose a new invisible infrared line-laser pattern for 3D face data acquisition.
