The objective of this study is to development T-shirts design using traditional window frame pattern for tourism souvenir. T-shirts design applied traditional window-frame pattern, which is a geometrical figure among traditional shapes. The results are as follows. 1. Window-frame pattern were general shape and complicated shape. 2. Window-frame pattern is visually ordered and stabled because has perfect ratio. 3. Geometrical line of window-frame applied on a T-shirt and match with modern sense.

  • The purpose of this study is to testify the pattern making method to develop the men's basic bodice pattern using 3-dimensional body scan data. The experimental patterns were made by adding wearing ease on flattened body scan data and tracing the outlines of it. The experimental bodice pattern were composed of front, back, and side panels. To compare the difference between the experimental pattern and traditional pattern, two pattern making methods were compared. Two sets of basic bodice patterns were made for each of the 10 male subjects: a set of pattern was made by experimental method and the other set was made by Bunka pattern making method. The experimental and traditional patterns were measured at 13 dimensions. The results show that there was a difference between the experimental patterns and traditional patterns at the front length, back length, front width, front neck width, back neck width, and back neck depth. The fit was also compared for both patterns. The results of the fit test show that the experimental patterns were superior to the traditional patterns at the fit of neck, shoulder, and armhole. The experimental pattern making method was expected to be useful for mass customization.

  • In this paper, we suggest the 3D Vision Inspection Algorithm which is based on the external shape feature, and is able to recognize the object. Because many objects made by human have the regular shape, if we posses the database of pattern and we recognize the object using the database of the object's pattern, we could inspect the objects of many fields. Thus, this paper suggest the 3D Vision inspection Algorithm using the Geometrical Pattern Matching by making the 3D database.

  • In this research, the fit of basic dresses was examined, by analyzing and comparing the satisfaction of fitness of basic dresses made by the draping method on a custom-made replica body form and that of a basic dress made by the flat pattern method. Basis dresses were produced by the draping method for each 52 subjects using custom-made body forms, and another kind basic dresses for each subjects were produced by the flat pattern method using measurements of body sizes. Both basic dresses received high scores for the satisfaction of fit, but the basic dresses produced by draping method received higher scores. Thus it is expected to produce a more successful fit by draping a basic dress on a custom-made body form. Future research using more subjects might confirm these results. A more concrete analysis through using additional satisfaction tests could be conducted. For example, each subject might also serve as an evaluator to rate her satisfaction of fit wearing each of the two custom-made dresses. Finally, examining various body forms is suggested.

  • It is well known that tire tread pattern has much influence on the tire pattern noise. The paper describes the method of pattern noise reduction by using the pitch sequence, both on the smooth asphalt roads and on the trenched concrete roads. The noise of tire is classified as either airborne or structure borne noise. Pattern noise through the airborne is considered as a major noise source at high speeds. As block impacting and air pumping by tread patterns are major noise source, tire pattern noise can be greatly influenced by optimal pitch sequence. The goal of this paper is to provide tire engineers with pitch sequence to reduce pattern noise effectively.

  • Detection of an anomaly pattern deviating normal data distribution in streaming data is an important technique in many application areas. In this paper, a method for detection of an newly emerging pattern in text streaming data which is an ordered sequence of texts is proposed based on text embedding and anomaly pattern detection. Using text embedding methods such as BOW(Bag Of Words), Word2Vec, and BERT, the detection performance of the proposed method is compared. Experimental results show that anomaly pattern detection using BERT embedding gave an average F1 value of 0.85 and the F1 value of 1 in three cases among five test cases.

  • Performance-Based Plastic Design (PBPD) method has been recently developed to evaluate the behavior of structures in different performance levels. The PBPD method utilizes a base shear force and a lateral load pattern that are estimated based on energy and yielding mechanism concepts. Using of current lateral force pattern results in weak structural members in upper stories of a structure so that the values of the story drift in these stories are larger than the target drift, particularly in high-rise buildings. Therefore, such distribution requires modifications to overcome this drawback. This paper proposes a modified lateral load pattern for steel Eccentrically Braced Frames (EBFs) based on parametric study. In order to achieve the modified load pattern, a group of 26 EBFs has been analyzed under a set of 20 earthquake ground motions. Additionally, results of nonlinear dynamic analyses of EBFs have been post-processed by nonlinear regression analysis in order to derive the new load pattern. To prove the efficiency of present study, three EBFs as examples were designed by modified pattern and current PBPD distribution. Inelastic dynamic analyses results showed that the story drifts using modified lateral load pattern were well within the target values in comparison with current pattern in PBPD, particularly where the effect of the height is significant. The modified load pattern reduces the possibility of underdesigning in upper levels and overdesigning in lower levels of the frames.

  • This study was conducted to define dietary patterns among 227 Korean American adults and 151 teenagers living in California using frequency of intake of major food groups and to examine associations of dietary patterns with selected demographic and acculturation variables. Three dietary patterns, 'healthful', 'Korean', and 'western', were identified using factor analysis. For both groups, 'healthful' pattern was characterized by high loading on milk/milk products, fruit, fruit juice, and bean/bean products. 'Korean' pattern had high loading on rice and kimchi. 'Western' pattern was characterized by high loading on meat/meat products, soda, and noodle/pasta. Among Korean American adults, women tended to have higher scores of 'healthful' pattern but lower scores of 'western' pattern, while there was no association of 'Korean' pattern with gender. The older adults were likely to have higher 'Korean' pattern score. Length of stay in the US and English levels were negatively associated with 'Korean' pattern. Korean American female adolescents had lower 'western' pattern scores than did male adolescents. Age was inversely associated with 'healthful' pattern in adolescents. The adolescents who had felt more proud of being a Korean descendant had higher scores on 'Korean' dietary pattern. The study findings support that dietary patterns are associated with acculturation variables such as length of residence in the US, English fluency, and particularly pride in ethnicity for adolescents. Further studies are needed to understand associations of dietary patterns and acculturation with health risk of ethnic groups.
