  • The purpose of this study was to establish a sizing system according to size and dimension whereby manufactured pants can be classified and develop men’s formal pants pattern based on the analysis of ready-made and educational pants pattern. The first, we surveyed the sizing and the basic pants patterns of the men’s ready-made wear companies, Secondly, through the survey data of the domestic men’ready-mad clothing industry, we proposed a new sizing system. Lastly, after compared three different types of ready-mad pants manufactured according to their patterns and an additional type of pants made after the educational pattern, the new men’s basic pants pattern were developed. The findings were as follows: 1. Survey of the domestic ready-mad garment industry showed that each company classified its own manufactured goods according to its own sizing system: moreover, they each used its own unique patterns which appeared to be resulted from a combination of two factors : the experience of a patterner and foreign know-how technology. 2. New sizing system was developed with 12 steps from size 74-88 to size 96-106 based on the high frequencies of the companies’3. New basic patterns for men’s formal pants were developed: Inseam length = 80cm, crotch line = H/4+4.6cm, pants ham = 23.5cm as basic lines and front waist girth =W/4+9.1cm as drafting line. 4. the superiority of the new basic patterns were been demonstrated by a high approval rate of the subjects who participated in testing.

  • This paper proposes a new quickly convergent pattern search quasi-Newton algorithm that employs the multi-step version of the Symmetric Rank One (SRI). The new algorithm works on the factorizations of the inverse Hessian approximations to make available a sequence of convergent positive bases required by the pattern search process. The algorithm, in principle, resembles that developed in [1] with multi-step methods dominating the dervation and with numerical improvements incurred, as shown by the numerical results presented herein.

  • The culture interest regarding the new area causes an effect even in change of fashion and that result Mongol area where it is area other than Japan, China and India and it is having compromised beauty raised it's head. Mongol is in Noin-ula area which is a it's former self of the Hun's. There is to a textile pattern which was used not only the textile pattern which has the feature of Scythian system but also the textile pattern which has the feature of China was used. The feature of Noin-ula's the textile pattern is as follows. Noin-ula's textiles used Scythian system of animal pattern, vine pattern, palmette pattern, thunder pattern, spiral pattern, shape of diamond pattern. Scythian system of animal pattern and vine pattern proves the interchange with the countries to the west of China. Noin-ula's textile pattern is applied to the designer's work of art. The designers are John Galliano, Etro, Chloe, Emmanuel Ungaro and so on, who express the modern ethnic style design. Because the more developed the modern society is the more embossed feature of intention for the race and the fork art, I think that Ethnic style design is applied to modern sensitive and ethnic style in the future.

  • In this study, we proposed the Bustier which improves the fit and functionality to compensate the physical defects by maximizing the volume up effect using the breast detailed measurements and shapes of the poor breast female subjects. Based on the preliminary study of the problem and preference according to the characteristics of the poor breast women consumers, we produced 1/2 volume mold cups based on the previous research. Respectively. A total of 5 subjects were selected, and new 3 bustier patterns based on the pattern making system of industry were created through direct measurement and shapes. As a result of verifying the usability of the developed bustier by testing the commercially available bustiers and the newly developed bustiers for 5 subjects. In order to compare the existing bustiers with the newly developed bustiers, the appearance evaluation by the expert, the evaluation of the adaptability and satisfaction by the subjects were utilized. Through this experiment, the newly developed bustiers were superior in the evaluation of the motion adaptability and wear comfort as well as appearance test. It was shown that the wear effect of the bustier with the longest back length was the best.

  • 현대산업의 주 구성요소인 컴퓨터 자동화는 섬유디자인 분야에 커다란 변화를 가져왔다. 패턴을 디자인할 때 수작업에만 의존해 왔던 디자이너들은 디자인과 색채의 다양성과 제작시간의 단축하기 위해 CAD를 디자인 도구로 하여 패턴을 창조하고 그것을 구매자에게 프리젠테이션하는 등 컴퓨터 활용이 보편화되고 있다. 당초무늬는 어느 특정식물을 소재로 패턴화 시킨 것이 아니라 이집트에서 발견된 인동문을 모체로 하여 발전된 공상적인 식물덩굴무늬로서 세계적인 무늬이다. 당초무늬는 줄기를 기준으로 꽃이나 잎이 서로 얽히어 연결됨으로서 아름답고 유연한 선을 나타내고 있으며 이 같은 선은 단순하면서도 장식적인 요소가 잘 표현되어 있다. 한국에서 당초문양은 장수와 다남을 상징하는 상서로운 문양이기 때문에 예로부터 우리 조상들이 즐겨 사용했으며 생활 속에 깊숙이 자리잡고 있다. 본 연구는 당초문양을 패턴의 모티브로 하여 CAD를 이용하여 패턴 디자인함으로써 디자인 개발의 다양성을 제시하였다.

  • Objectives This study is aimed at assessing the reliability of the Pattern identification questionnaire (PIQ) developed by Korea Institute of Oriental Medicine and examining the validity of the PIQ by comparing the pattern identification scores of different groups. Methods We conducted a survey of 258 participants (79 teachers and 179 graduate students at one School of Korean Medicine) using self-reported questionnaire and all the samples were retested. The test-retest reliability was assessed by Kappa coefficient(${\kappa}$) and Pearson correlation coefficient. Also we compared the differences in pattern identification scores according to sex, age and occupation. Results 1. One of 116 questions are impossible to calculate; 22 of them (18.97%) scored under 0.4 in ${\kappa}$; 90(77.59%) ranged from 0.4 to 0.8 in ${\kappa}$; and three questions (3.58%) scored 0.8 or over in ${\kappa}$. 2. Pearson correlation coefficients between test score and retest score of all pattern identification items are 0.4 or over. 3. The mean score for pattern identification in women was generally higher than that in men, particularly in patterns of blood-deficiency, blood-stasis, yang-deficiency and kidney disease. 4. The mean score for pattern identification in the graduate student group was generally higher than that in the teacher group. Conclusion In test-retest reliability, the PIQ showed relatively high reliability. The mean pattern identification score showed differences in regards to retaining knowledge about Korean medicine. Therefore, future research involving modification of questionnaire items and confirming the validity of this questionnaire is required.

  • Objectives: Several pattern diagnosis questionnaires have been developed to objectify the process of pattern diagnosis in Korean medicine. In this context, this study aimed to develop a food retention questionnaire for functional dyspepsia (FRQ-FD) by modifying the previously developed food retention questionnaire (FRQ) and to verify its reliability and validity. Furthermore, this study aimed to identify the optimal cut-off value of the FRQ-FD for standardization and use in clinical situations. Methods: To develop the FRQ-FD, we extracted the major symptoms of food retention pattern for functional dyspepsia from Chinese/Korean medicine textbooks and requested an importance survey from experts using the Delphi method. The first draft of the FRQ-FD was composed of 25 questions comprising 8 questions from the textbooks and the Delphi method and 17 questions from the FRQ already developed in 2013. To analyze its reliability, validity, and optimal cut-off value, 60 subjects were enrolled in this study from June 25 to August 13, 2018. Thirty patients were diagnosed as both functional dyspepsia and food retention pattern, and 30 healthy participants were not. All participants were requested to fill up the FRQ-FD, Stomach Qi Deficiency Questionnaire (SQDQ), Scale for Stomach Qi Deficiency pattern (SSQD), visual analog scale (VAS) for dyspepsia, Nepean Dyspepsia Index-Korean version (NDI-K), and functional dyspepsia-related quality of life (FD-QoL). Results: No statistically significant differences were found in sex distribution, age, and body mass index between the patient group and the control group. As five questions affected the reliability negatively and three questions affected the clinical validity negatively, we decided to exclude the eight questions upon further investigation. The Cronbach's ${\alpha}$ coefficient of the revised FRQ-FD (17 items) was 0.899, and its clinical validity was verified. Construct validity was analyzed by factor analysis and produced five factors. Statistically significant positive correlations were found between the revised FRQ-FD and the other dyspepsia scales, namely, SQDQ, SSQD, VAS, NDI-K, and FD-QoL. VAS and NDI-K especially had strong positive correlations with FRQ-FD. Conclusions: The FRQ-FD developed in this study can provide fundamental reliability and validity for a pattern diagnosis questionnaire. FRQ-FD can help to diagnose food retention pattern in functional dyspepsia patients. Further studies are required to inspect several statistical factors.
