Recent development of 3D scanner and software is regarded as a promising method of acquiring replicas from human body indirectly. It would be very helpful if we could predict the characteristics of 2D pattern from the simple parameters related to 3D shape for ordinary user. Therefore, in this study, investigation of 2D pattern of waist/abdominal area from the 3D geometrical model was conducted for the pattern development of waist nipper. To create body models and develop the surface of them, one ortho commonly used CAD/CAM program, IDEAS(UGS-plm solutions, USA) was used. As for the size of the models, the width, thickness, and circumference ranges of adult women's torso reported in National Anthropometric Survey of Korea (1997) were used as a standard model. Seven size variations were made by changing the width of the waist only, from 19 cm to 40 cm. Therefore, simulated body models include not only the normal body but also obese body who has wider waist and abdomen width than hip width. As results, it was found that the curvature of the unfolded 2D pattern around the abdominal area decreases as the waist width increases. As the width of the waist increases more and more, so that the comparative ratios around the torso becomes in abnormal ranges, there appears inflection points and the direction of curvature was changed. 2D Patterns obtained in this research were quantified by curvature, length of the curve and angle of deflection in the reference frame box for the convenience of the actual pattern making process. It was also possible to find that the shape of patterns of abnormal body resulted in a quite interesting change in the curves of 2D pattern, which could be applied to the custom made waist nipper for obese women.

"Aloha" is the Hawaiian word that extends the warmth friendliness, and pride of the Hawaiian people to their island's visitors. The aloha shirt truly symbolizes aloha sprit to islanders and visitors alike. The earliest foreign settlers in the Hawaiian Islands were the Chinese and Japanese. They brought with them their myriad talents and trades, among them the art of tailoring. In July of 1936, a shirtmaker named Ellery J.Chun coined the term "Aloha Shirt" an apt characterization for such an eloquent garment. He was the first to make the shirt on a commercial basis. The shirt sold for as little as a dollar in Chun's own King-Smith store. The genuine aloha shirt is now regaled as a work of art and avidly sought out by collectors. When tourism came to Hawaii in the late 1930s, these unusal shirts were among the first thing that visitors had to have. Local designers and tailors worked quickly to meet the demand and began to expand the range of decoration to include palm trees and romantic beaches, tropical jungles and volcanoes, exotic flowers and scenes from polynesian legend. Therefore the aloha shirt had been born. The functional use of creative colors and amazing artistic renderings in these shirts certainly capture the simplicity and sprit of Hawaii. Aloha shirt is dress that display mystery and charm of Hawaii and cultural symbol of condensed Hawaiian mind. Furthermore, the innocence with which Hawaiians formerly translated their life and heritage onto fabric ranks these shirts with the finest of American folk art. Aloha shirt is made from cotton, silk, rayon in present and past. Most important design element of Aloha shirt is print pattern. Main print pattern of Aloha shirt are all over pattern, horizontal pattern, border pattern, Japanese pattern, picture pattern and back panel pattern. In this study I investigate the design characteristics and development process of aloha shirt.

Objective: The purpose of this study is to develop an all- in-one collar shirt with excellent appearance which is well suited to the body shape of the male adults. Background: As men's casual wear has recently become more casual and the number of cool biz wearing in the summer has increased, a variety of shirt colors have been preferred in addition to shirt collar. However, studies on the design and pattern development of men's casual shirt collars are very rare. So we have identified the necessity of various development and research of men's shirts. Method: We collected 8 all-in-one collar patterns for shirts from professional pattern books and men's shirt brands. Also, based on anthropometric data from the 6th Size Korea, we selected 5 subjects with measurements similar to the average adult men, manufactured shirts based on them and conducted a wearing test by 5 experts. Results: After selecting shirts with good fit and appearance, we developed a prototype of all-in-one collar. As for front appearance evaluation, E1 pattern had the most outstanding shape and size, and C1 pattern had the most natural creases and front adjustment curves. As for side appearance evaluation, C1 had the highest overall scores, and E1 pattern on outer line. As for back appearance evaluation, C1 pattern had the highest score. Conclusion: We suggested new all-in-one collar and shirt patterns. In addition, the prototype of the all-in-one collar shirt design was presented by reflecting results of the wearing test and preference survey. Application: The shirt's design and patterns could be manufactured using the developed patterns. It will fit well with the body shape of adult males and will be highly satisfied by them.

The purpose of this study was to examine the appropriate surplus of clothing for a suitable basic bodice pattern of Male Sports Athletes by using the 3D virtual twin and virtual garment simulation system. The results were as follows; 1. By using 3D virtual twin and garment simulation, new bodice pattern considered male sports athletes was development. The basic numerical formula were as follows ; surplus of chest girth=9, surplus of back length=1, armhole depth=back length/4+13, half back width=chest girth/5+2.5, front chest width=chest girth/5+3. 2. Wearing test by 3D virtual garment simulation system was useful to evaluate wearing outline, surplus of clothes and garment space. Also it estimated more highly than existing pattern in silhouette and ease amount, confirming that new bodice pattern is appropriate for the male sports athletes. New bodice pattern was evaluated to allow proper space length of chest and waist. Virtual models production through 3D body scan data, pattern draft and virtual garment digital program were applied to prototypic design method so as to enhance the fitness of ready-made garments. This study is expected to serve as one of important basic data for ensuing studies that may utilize 3D Virtual Garment Simulation System with 2D patterns, and also for future 3D Pattern Production Program development.

Underwater radiated noise is the key in acoustic stealth performance of modern naval ships. The underwater radiated noise predicted by the hull vibration with radiation efficiency cannot always give the information of radiation pattern which is essential to analyze of detection probability by enemy and to improve the operational performance of the naval ship. The radiation pattern of underwater radiated noise is able to be obtained with radiation efficiency and radiation directional coefficient. In this paper, a new method to extract the radiation efficiency and radiation directional coefficient is suggested and proved with the simulation and experiment by using cylindrical shell of 70 cm diameter in air.

Purpose: This study was done to develop a measure resilience in nurses. Method: Forty preliminary items were extracted from a view of the literature on concept analysis and scale development, and from in-depth interviews with nurses. These items were examined for content validity, reliability and validity. The scale was verified with 496 nurses working in three advanced general hospitals located in Seoul and Gyeonggido. Results: Factor analysis resulted in the creation of the final scale, which consisted of 30 items that were grouped into 5 factors: dispositional pattern, relational pattern, situational pattern, philosophical pattern and professional pattern. The explanatory variance was 56.25%. The reliability of the scale was Cronbach's ${\alpha}=.95$. Correlation of the scale with the Korean version of the Connor-Davidson Resilience Scale (K-CD-RISC), established its construct and concurrent validity (r=.74, p<.001). Conclusion: The resilience scale for nurses was found to have reliability and validity, and as developed in this study reflects nurses' disposition and was confirmed as a basis for developing and evaluating programs to increase nurses' resilience.

With the advent of the Information Age, the source identification of digital images, as a part of digital image forensics, has attracted increasing attention. Therefore, an effective technique to identify the source of digital images is urgently needed at this stage. In this paper, first, we study and implement some previous work on image source identification based on sensor pattern noise, such as the Lukas method, principal component analysis method and the random subspace method. Second, to extract a purer sensor pattern noise, we propose a sample selection method to improve the random subspace method. By analyzing the image texture feature, we select a patch with less complexity to extract more reliable sensor pattern noise, which improves the accuracy of identification. Finally, experiment results reveal that the proposed sample selection method can extract a purer sensor pattern noise, which further improves the accuracy of image source identification. At the same time, this approach is less complicated than the deep learning models and is close to the most advanced performance.
