  • The purpose of this research is to know the pattern of Hanbok Jegory with measuring Jegory and studying manufacturing method of the Jegory used currently. It is a purpose to find constitutional problem caused by the character of the bending somatotype and, to study the standard model of the Jegory for bending somatotyped women in old age, by comparison of this fitness for bending-somatotyped women in old age. The results obtained are as follows; 1. The kinds of measurements considered in manufacturing process are Hwajang Length, Bust girth, and the skirt length. The length of Jegory and width of Neck are also considered. 2. Manufacturers consider somatotype the most important thing when they make Jegory for women in old age. Front length, Back length and Width of the Jegory are considered secondly important. 3. The results of the comparison show that the Standard Hanbok drafting method is not suitable for drafting Jegory for bending somatotyped women in old age. 4. The suitability test for the model designed by the above methods shows that it fits in bending somatotyped women in old age better than standard drafting method. The results show the superiority of the above methods especially in the breast width, the Godae length, and the adaptedness to the body.

  • The thinning process which is commonly used in extracting skeletons from handwritten Hangul characters has a problem of distorting the original pattern shapes. This paper proposes a method of skeleton extraction using a shape decomposition algorithm. We decompose the character pattern into a set of near convex parts using a shape decomposition algorithm. From the shape-decomposed pattern, we detect the joint parts and extract the skeletons from the parts incident to the joint parts. Then the skeletons not incident to the joint parts are extracted. Finally, the process of skeleton extension is performed to ensure the connectivity. We setup five criteria for the comparison of quality of skeletons extracted by our method and the thinning based method. The comparison shows the superiority of our method in terms of several criteria.

  • The purpose of this study is to compare how the number of panels, the amount of flare and the flare starting point affect the silhouette of the gored skirt. This study consisted of (1) creation of 3D body representations (2) comparison of silhouette between 3D virtual gored skirt and actual gored skirt by pilot experiment (3) pattern drafting of twenty-seven different gored skirts for 3D body representations (4) a computer simulation of twenty-seven different gored skirts for visualization and assessment (5) visual inspection of twenty-seven different 3D virtual gored skirts (6) comparison of ham shapes and measurements for the node and size analysis. A visual inspection of twenty-seven different 3D virtual gored skirts showed clear differences by the amount of flare and the flare starting point ; however, there was notably less difference in the width of ham among six-piece, eight-piece and ten-piece panels. This demonstrated that there was less influence on the number of panels than the amount of flare width of ham and extent of ham for the 3D virtual gored skirt.

  • Several damage counting methods can be applied for the fatigue issues of a ground vehicle system using strain data and acceleration data is partially used for a high cyclic loading case. For a vibration test, acceleration data is, however, more useful than strain one owing to the good nature of signal-to-random ratio at acceleration response. The test severity can be judged by the fatigue damage and the pseudo-damage from the acceleration response stated in ISO-16750-3 is one of sound solutions for the vibration test. The comparison of fatigue damages, derived from both acceleration and strain, are analyzed in this study to determine the best choice of fatigue damage over multi-spectral input pattern. Uniaxial excitation test was conducted for a notched simple specimen and response data, both acceleration and strain, are used for the comparison of fatigue damages.

  • In this paper, In this paper, we use two methods to compare the slim speakers. That way, the diaphragm scan using laser and diaphragm photographed using a thermal imaging camera. Slim speaker has the structure of a flat plate type. Break-up mode by this characteristic is displayed in a larger size. Further, since the installation space is narrow, it has limited moving coil cooling. As a result, the break-up mode slim speakers, a significant impact on quality. In this study, try to connect the break-up mode of the diaphragm, the heat transfer mode of the diaphragm. Experiment for comparison, a two-step. The first step is to measure the divided vibration through the vibration plate scan. The second step measures the diaphragm photographed using a thermal imaging camera. Then, compare the results of both of the same frequency. Thus, comparing the heat transfer pattern and the pattern of break-up mode. Tend to be analysis of break-up mode from the pattern comparison, and document for the optimum design.

  • The cymbal transducer is a miniaturized version of the Class V flextensional transducer. It has low resonant frequency and high output pressure characteristics compared with its size. However, since it has high quality factor and low energy conversion efficiency as well, it is often used as an array rather than single. When used as an array, a big change in the frequency characteristics occurs in comparison with that of the single transducer due to the interaction between constituent transducers. In this study, we designed a pattern of cymbal array with a view to having broadband characteristics. Three transducers having different center frequencies were designed first. The designed cymbal transducers were used to construct all possible patterns of a 3 × 3 planar array. After analyzing frequency characteristics of these patterns, based on the results, we derived the most effective pattern to achieve a higher fractional bandwidth. The derived array pattern showed an improvement of the fractional bandwidth by 24.9 % in comparison with the reference model.

  • Purpose: The study aims to examine the effects of the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy on pain, range of motion (ROM), and shoulder dysfunction in breast cancer patients. Methods: In total, 30 breast cancer patients were recruited and randomized to group I (n = 10), group II (n = 10), and group III (n = 10). Pain was measured using a visual analogue scale, ROM was measured using a goniometer, and shoulder dysfunction was measured using a shoulder pain and disability index. Group I practiced the proprioceptive neuromuscular facilitation pattern exercise and underwent scrambler therapy, group II underwent scrambler therapy only, and group III practiced the proprioceptive neuromuscular facilitation pattern exercise only. Results: A within-groups comparison showed that all groups demonstrated significant differences in pain, ROM, and shoulder dysfunction after the experiment (p<0.05). Further, according to a comparison of the three groups, group I showed a more significant difference in effectiveness than groups II and III in terms of pain, ROM, and shoulder dysfunction before and after the experiment (p<0.05). Conclusion: This study showed that the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy are effective in treating pain, ROM issues, and shoulder dysfunction in breast cancer patients.

  • Objectives : The purpose of this study was to develop the Korean standard pattern identifications for stroke-III (KSPIS-III). KSPIS-III includes 4 major pattern identifications (PIs) and clinical indicators for each. Methods : To extract the indicators for 4 major PIs, we analyzed 1548 clinical data from 15 traditional Korean medicine hospitals. Patients got acute stroke within 30 days from onset. Two physicians independently checked 65 indicators and performed pattern diagnosis. If the PI were diagnosed the same, PI would be confirmed. First we built an assumption model that set up the relationship among pattern identifications. Second, we extracted the indicators for fire-heat pattern and qi deficiency pattern by comparison between excessive and deficiency group, heat and non-heat group. By comparing yin deficiency pattern and 3 other patterns respectively, we extracted the indicators for yin deficiency pattern. Dampness-phlegm pattern indicators were extracted by the same method. Results : After cross tabulation with 65 indicators on the basis of our assumption model, we finally extracted 19 indicators for fire-heat pattern, 11 for qi deficiency pattern, 7 for yin deficiency pattern, and 7 for dampness-phlegm pattern. Conclusions : KSPIS-III was more improved than KSPIS-II because it was based on more clinical data. Further study to establish the PI diagnostic model would be required for practical use in the clinical field.

  • The results of stand and field testing of a combustion chamber for a heavy-duty 150 MW gas turbine are discussed. The model represented one of 14 identical segments of a tubular multican combustor constructed 1:1 scale. The model experiments were executed at a lower pressure than that in a real gas turbine. Combustion efficiency, pressure loss factor, pattern factor, liner wall temperature, flame radiation, fluctuating pressure and NOx emission were measured at partial and full loads for both model and on-site testing. The comparison of these items in the stand and field test results led to has the development of a method of calculation and the improvement of gas turbine combustors.
