  • 패턴완성(Pattern Completion)은 사용되는 패턴 성분들 사이의 higher-order correlation 정보가 중요한 의미를 가질 수 있는 기계학습 문제 중 하나이다. higher-order correlation은 확률라이브러리모델(Probabilistic Library Model)로 구현되는 hypernetwork 개념을 도입해서 나타낼 수 있다. 하지만 확률라이브러리모델을 사용하여 higher-order 정보를 나타내려할 때 초기라이브러리가 모든 가능한 조합의 원소들을 가지도록 구성하기는 쉽지 않다. 그 대안으로 초기라이브러리 구성 시 학습패턴들을 subsampling하여 적은 숫자의 원소들만으로 higher-order correlation의 근사치를 나타내게 할 수 있다. 본 논문에서는 이와 같이 subsampling이 사용되어 구성된 확률라이브러리모델을 이용한 패턴완성시의 correlation의 order에 따른 효과를 분석하여 본다.

  • On the subjects of the female adults in their 20s who love to wear jeans, the wearing reality of basic jean pants and engineered jean pants was examined while pattern comparison and the evaluation of appearance and functions were made to reach the following conclusions: 1. Wearing reality of engineered jean pants Among the examined subjects, 74.8% were found out to favor engineered jean pants. Those who have engineered jean pants turned out to pursue well-known brands more than practicality. 2. Pattern comparison analysis of basic jean pants and engineered jean pants Though similar sizes existed in pants tips and belt width, engineered jean pants showed bigger values in waist circumference, crotch circumference, hip circumference, knee circumference, thigh circumference and so on. There were no big differences in the front part except for the items like crotch circumference and crotch length, but engineered jean pants had bigger sizes in the rear part. Engineered jeans in the rear contained the outward curved silhouette of the legs, curved tips, and a dart design instead of a back yoke. 3. Evaluation of appearance and functions In the scores of appearance, basic jean pants were higher at 3.65 in the order of front > side > back. On the contrary, engineered jean pants were excellent in the order of side > back > front. In the items of functions, engineered jean pants were higher at 4.23 in the order of hips > thighs> waist > abdomen > knee > crotch. On the other hand, basic jean pants showed the order of knee > crotch & thighs > abdomen > hips > waist. In every movement, engineered jean pants revealed higher functionality. In particular, the bigger physical movement led to the greater functional differences between the two kinds of jean pants.

  • The use of primitive cell volume and zero order Laue (ZOLZ) pattern is proposed to identify phase in a complex microstructure. Single convergent beam electron pattern containing higher order Laue zone ring from a nanosized region is sufficient to calculate the primitive cell volume of the phase, while ZOLZ pattern is used to determine the zone axis of the crystal. A computer program is used to screen out possible phases from the value of measured cell volume from convergent beam electron diffraction (CBED) pattern. Indexing of ZOLZ pattern follows in the program to find the zone axis of the identification from a single CBED pattern. An example of the analysis is given from the rapidly solidified $Al-Al_3Ti$ system.

  • 본 연구에서는 재활정도를 정량적으로 표현하기 위하여 정상 보행과 모의 비정상 보행 시 보행주기에 따른 근전도 패턴에 고차 곡선 맞춤을 적용하여 분석하였다. 보행 근전도 패턴에 적합한 다항식을 생성하였으며, 그 변수를 군집분석 하여 5개의 그룹으로 분류하였다. 정상패턴을 포함한 그룹을 기준으로 거리가 가까운 그룹을 나열하여 각 변수의 분포를 확인하였다. 진폭감소 패턴, 불규칙 패턴, 역상 패턴 순으로 정상 패턴에 유사하였으며, 분류된 그룹의 분포는 중첩되는 범위가 작아 변수 값을 이용한 그룹 분류가 가능하였다. 분류된 재활정도를 정량적으로 나타내기 위하여 각 계수항의 표준편차를 패턴별로 비교하였고, 정상에 가까울수록 큰 값을 가지는 것을 확인하였다. 역상 패턴의 경우는 편차 값은 크지만 부호가 음의 값을 가지므로 가장 작았다. 본 연구의 결과인 정량적인 재활정도의 표현은 보다 효율적인 재활방법 연구에 기여할 것으로 예상된다.

  • 대부분의 빈발 패턴은 패턴이 트랜잭션 데이터베이스에 나타나는 support를 패턴 interestingness의 핵심 척도로 다루어 왔으나 패턴의 횟수는 패턴의 completeness가 가지는 정보를 최대치로 가정하고 있다. 그러나 실제적으로는 임의의 패턴 X의 completeness는 트랜잭션에서 서로 다르게 나타나기 마련이다. 따라서 패턴이 가지는 정보의 손실을 줄이기 위해서는 가중치에 의한 support와 completeness에 의한 유용한 패턴 마이닝을 고려하여야 한다. 즉, 높은 completeness율을 갖는 패턴은 더 높은 recall로 이어질 수 있고 높은 빈도수를 갖는 패턴은 보다 높은 정밀도로 이어진다. 본 논문에서는 동적인 항목들의 가중치에 따른 적응된 support와 completeness를 고려하는 WSCFPM 패턴 마이닝 알고리즘을 제안한다. 제안한 방법은 모노톤 또는 반 모노톤 속성이 가중치에 의한 support와 completeness에 영향을 미치지 않기 때문에 탐색과정을 줄일 수 있다. 실험결과를 통하여 제안된 알고리즘이 효과적이며 확장성이 좋은 것임을 보인다.

  • Objectives : Cnidii Fructus is prescribed as the fruit of Cnidium monnieri (L.) Cusson or Torilis japonica (Houtt.) DC. in Korea pharmacopoeia. Although there are differences in the composition of useful components, two species have been used without distinction. In order to discriminate them, DNA sequencing and taste pattern analysis were used in this study. Methods : Primers ITS 1 and ITS 4 were used to amplify the intergenic transcribed spacer(ITS) region of nuclear ribosomal DNA from seven T. japonica and six C. monnieri samples. Taste pattern of samples were measured by using taste-sensing system SA402B equipped with five foodstuff sensors(CT0, C00, AAE, CA0, and AE1). The five initial taste(sourness, bitterness, astringency, umami, and saltiness) and three aftertaste(aftertaste of bitterness, astringency, and umami) of two species were compared. Results : According to the results of ITS region sequence analysis, two species showed 94 base pairs differences. The similarity of two sequences was 85%. From the taste pattern analysis, sourness, bitterness, aftertaste of bitterness(aftertaste-B), and umami showed a different pattern. Especially, bitterness and aftertaste-B of C. monnieri were significantly higher than T. japonica. In addition, two species were shown to have two markedly different clustering by these two flavors. Conclusion : T. japonica and C. monnieri were effectively discriminated using DNA sequencing and taste pattern analysis. These methods can be used to identify the origin of traditional medicine in order to maintain therapeutic efficacy.

  • Objectives: This study was performed to obtain reference data of traditional Korean medicine diagnostic methods for the practical usage in women infertility. Methods: The study involved 38 female patients of age 20-38 years that had diagnosed of infertility. All the subjects answered to pattern identification questionnaire and Questionnaire for the Sasang Constitution Classification (QSCC II). Pattern identification scores and constitution types have been analyzed with variables of infertility factors and age. Statistical analysis was performed by adopting descriptive and inferential tests. Results: In pattern identification questionnaire analysis, the patterns were observed in order of frequency: liver stasis; blood deficiency; kidney-yang deficiency; kidney-yin deficiency; damp-heat; blood stasis; and phlegm. The group, less than 35 years old, had the higher average score of liver stasis (p<0.05). Also, the group with tubal and peritoneal factors, had the higher average score of blood deficiency (p<0.05). In QSCC II analysis, So-yang type had the higher average score of liver stasis, kidney-yang deficiency, and kidney-yin deficiency. So-eum type had the higher average score of liver stasis, kidney-yang deficiency, kidney-yin deficiency, and blood deficiency. While, Tae-um type had the higher average score of liver stasis and phlegm. Conclusions: We would accumulate the clinical data for the practical usage of traditional Korean medicine diagnostic methods in women infertility.

  • This study was conducted in order to analyze draping and flat pattern according to jacket design, and provide basic materials for developing a jacket pattern that can enhance fitness, functionality, and aesthetic expression of clothes by reflecting esthetic expression of draping and efficiency of flat pattern at the same time. For the experimental jacket designs of a one-piece sleeve jacket and a two-piece sleeve jacket were selected among the entries of the designer Rubina for 2014 F/W Seoul Fashion Week. Designer brand Rubina usually produced clothes using draping and the designer brand company provided the experimental patterns for the study. We also had flat patterns of the same design and size specifications designed by a flat patternmaker who has 30 year-experience in flat pattern like Rubina. The test apparel jacket was made of 20's cotton yarns. Three models wore the jackets and evaluation on appearance fitness was conducted by 7 members in an expert panel group from August 10, 2015 to September 10, 2015. As a result of appearance fitness analysis on one-piece sleeve jacket, there were significant difference in 4 items among 17 items in terms of overall appearance. The appearance of jackets by draping had higher score than those using flat pattern. As for two-piece sleeve jacket, there were significant differences in 7 items among 17 items related to overall appearance. As for the items related to sleeve, 5 items out of 13 showed significant differences. Except for one item, appearance of jackets using draping had higher score than flat pattern. As for motion fitness, draping was evaluated to be more comfortable. Applying the items with high scores in appearance and motion fitness in draping to flat pattern, The study suggests a new jacket pattern development that would increase the satisfaction of consumers for future research.

  • The purpose of this study is to find out more rational way to manage clothing. The study is based on a survey of daily clothing practices. 112 female college students who are majoring clothing, textiles, and/or home economics have responded to the questionnaires. With the samples, frequency, factor analysis, discriminant analysis, ANOVA, and Scheffe test are pursued respectively. Main results of the survey analysis could be summarized as follows : 1. Female college students are found to possess 70 units on average. They possess more of casual clothes such as polo·T shirts, casual pants, and casual shirts (from the highest frequency in order). They possess less of formal clothes such as one-piece and two-pieces (from the lowest frequency in oder). 2. It is found that 12 per cent of the possessed clothings are not used at all during the year. The unused rate is higher for the formal suits while it is lower for the casuals. 3. The possession pattern is affected by clothintg life style factors : brand and economic factors for the casuals ; fashion and individuality factors for the formals. 4. The possession pattern is also affected by the purchasing behavior factors, purchasing price among others.

  • Most of the underwater noise emitted by small fishing boat are owing to vibration of main engine and generator etc.. This paper describe on the spectrum analysis of underwater noise by engine generating in small fishing boat in order to build up comfortable environment for fisheries man and to reduce ambient noise. The obtained results are summerized as follows:1. When the underwater noise of 10ton class fishing boat measure and the frequency spectrum in varied revolution of engine 750, 900, 1000rpm analyze, the frequency pattern is similar to each other, the faster revolution of engine increase, the higher frequency spectrum level becomes. 2. In comparison of spectrum level of underwater noise between 10ton class and 14ton class fishing boat, the former level is higher than the latter. 3. Frequency spectrum pattern of two 14ton class fishing boat is similar to each other but spectrum level is a little difference, it is suggested to different by fitting condition of engine.
