넷플릭스, 아마존, 유튜브 등 대형 플랫폼에서는 고객의 다양한 정보를 활용하여 정밀한 추천시스템을 마련하고 여기서 추천된 상당수의 아이템이 실제 구매로 이어지고 있다. 본 논문에서는 추천 컨텐츠의 속성에 따라 사용자의 선호도에 차이가 있을 것이라고 예상하고 콘텐츠의 속성에 따라 군집분석을 실시하였다. 속성의 형태와 관계없이 사용할 수 있도록 Gower 거리를 사용했다. 본 논문에서는 영화 평점 사이트인 'The Movie Dataset'의 자료를 이용하여 영화의 기본정보인 장르, 감독 및 배우 변수를 바탕으로 사용자를 계층적으로 분류하고 영화를 추천하였다. 본 논문에서 제안한 추천 시스템을 평가하기 위하여 각 사용자 그룹별로 훈련자료와 검증자료로 나누어 정밀도를 살펴보았다. 그 결과 UBCF보다 월등히 높은 정밀도를 갖는 것으로 나타났다. Global platforms such as Netflix, Amazon, and YouTube have developed a precise recommendation system based on various information from large set of customers and many of the items recommended here are leading to actual purchases. In this paper, a cluster analysis was conducted according to the attribute of the content, expecting that there would be a difference in user preferences according to the attribute of the recommended content. Gower distance was used for use regardless of the type of variables. In this paper, using the data of movie rating site 'The Movie Dataset', the users were grouped hierarchically and recommended movies based on genre, director and actor variables. To evaluate the recommended systems proposed, user group was divided into train set and test set to examine the precision. The results showed that proposed algorithms have far higher precision than UBCF.

김윤경 ( Yoon Kyoung Kim ) 한국의류학회 2020 한국의류학회지 Vol.44 No.3

This study researches the association between associative vocabulary and fashion image language in order to extract ideas that can be used as basic data for design ideas. Classic - avant-garde imaged language were chosen as theme words and each 70 questionnaires per a final image word were used for analysis. We obtained the following results by researching keywords that explained classic image words through a word cloud technique. It was found to have high central representation in the order of suit, classical, basic, music, Chanel, black and traditional. The core key words explaining avant-garde image language were found to have a central representation in the order of : peculiar, huge, Comme des Garçons, artistic, creative, deconstruction and individuality. We extracted the necessary idea dimensions needed for design ideas through associative network graph analysis. In the case of classical image language, it was named as the Mannish Item, Music, Modern Color, and the Traditional Classicality dimensions. In the case of avant-garde image language, it was named as the Key Image, Artistic Aura, Key Design and Designers dimensions.

The purpose of this study is to present the objective evaluation semantic scale of avant-garde design. Apparel majors were asked to express associative vocabulary, design development, and final design intentions for the avant-garde, and the final 70 copies were used for analysis. The results found the item style was shown often in the order of dress, coat, and combination of shirt and pants. In order, the silhouettes appeared as atypical, complex, square, and triangular; the decorations appeared as feathers, frills, and round sculptures; and the idea method appeared as extreme, association, and removal method. In examining the relations of associative words and idea designs, the dress had relations with associative words such as ‘peculiar,’ ‘futuristic,’ ‘fancy,’ ‘Comme des Garcons,’ and ‘deconstruction.’ As for the relationship between the idea design and the expression image vocabulary, it was found that ‘one piece’ recalled ‘huge,’ ‘volume,’ ‘abundant,’ ‘peculiar,’ and ‘unknown,’ while ‘coat’ recalled ‘huge,’ ‘big silhouette,’ and ‘padding.’ In conducting the word cloud technique, the overall design showed the central keywords were ‘huge,’ ‘big silhouette,’ ‘unbalance,’ ‘feather,’ ‘structural,’ ‘unknown,’ and ‘frill,’ in order.

본 연구에서는 산성전리수의 일반적인 생물학적 특성을 간략히 살펴보았다. 직선형 DNA를 산성전리수에서 4℃와 25℃에서 약 10분간 반응시킨 결과 각각 40%와 50%의 DNA가 분해되었다. 그러나 산성전리수를 사용한 고온에서의 DNA 증폭반응 실험에서 DNA 분해없이 정상적으로 DNA 증폭반응이 일어났다. 산성전리수가 단백질의 안정도에 미치는 영향을 살펴본 결과 증류수에서는 총 7일 동안의 반응시간동안 단백질의 분해가 거의 일어나지 않았으나, 산성전리수에서는 제4일에서부터 단백질의 분해가 본격적으로 일어나기 시작하였다. 산성전리수에서 볍씨를 발아시켜 본 결과 증류수에서와 동일한 발아율을 나타냈으며, 산성전리수는 배양토에서 벼 유묘의 뿌리의 길이와 총 길이를 억제시킨다. 산성전리수는 해양미세조류의 성장곡선과 세포수에는 거의 영향을 미치지 않았다. 또한 산성전리수는 Polyphenol oxidase의 비활성을 약 50% 억제시킴으로써 감자의 갈변을 억제하였다. Biological characteristics of anodic electrolyzed water were investigated in this study. Linear DNAs which were incubated at 4? and 25? for 10 mins in the anodic electrolyzed water were degraded about 40% and 50%, respectively. But the DNA was amplified pretty well without any degradation through polymerase chain reaction in the presence of anodic electrolyzed water. Protein degradation hardly occurred in the distilled water during entire incubation time of 7 days, while protein began to be degraded from 4 days in the anodic electrolyzed water. Rice seeds could germinate in the distilled water and anodic electrolyzed water with the same germination ratio, however, the anodic electrolyzed water inhibited the growth of roots and total length of rice seedlings in the soil. Anodic electrolyzed water did not affect the growth curve and cell number of marine alga significantly. The anodic electrolyzed water inhibited the browning of potato by inactivating 50% of polyphenol oxidase activity.

It is experiencing the difficulty of communication in daily life degrading the clarity of speech by the reduced intensity of sound that is speech characteristics of patients with Parkinson’s disease. Lee Silverman Voice Treatment is a program developed taking notice that the reduced intensity of sound with the characteristics of Parkinson’s disease is the main reason to degrade the clarity of speech. This program will increase the intensity of the voice with intensive care and is focusing on maximizing the phonation and respiration effort. Precedent research on whether the effects of LSVT program being used much in clinical practice currently is actively taking place, but it is difficult state to generalize because most of the studies have been made under limited samples. Therefore this study was integrate the results by collecting the existing precedent studies on whether the intensity improvement effects of Parkinson’s disease by LSVT program in each task of vowel phonation, reading, monologue and doing meta analysis for these.Research methods was selected 10 units of study systematically depending on the inclusion and exclusion criteria of the study after reviewing the relevant literature of domestic and foreign in the subject of “parkinson & LSVT. It was calculated the overall effect size of studies selected using random effects model. The analysis results of the vowel phonation, reading, monologue task, first, the result performed homogeneity test in the vowel phonation task is p-value=0.99609 and each study is homogeneity with each other, test result of the overall treatment effect is p-value<.0001 and can be considered significant. Second, the result performedhomogeneity test in the reading task is p-value=0.99909 and each study is homogeneity with each other, test result of the overall treatment effect is p-value<.0001 and can be considered significant. Third, he result performed homogeneity test in the monologue task is p-value=0.99115 and each study is homogeneity with each other, test result of the overall treatment effect is p-value<.0001 and can be considered significant. In the analysis results, it can be confirmed that it was improved all the intensity of vowel phonation, reading,monologue. Therefore the result verified the overall effect of LSVT program by each variable is that because p-value for all the variable is smaller than statistical significance level 0.05, LSVT program may be effective in promoting intensity. And in order to see the risk of each study of vowel phonation, reading, monologue,average distribution was appeared by drawing point chart.This study has a great significance that the intensity improvement effect of LSVT program was integrated systematically through the way called meta analysis. It can be considered that this study can be utilized highly in clinical that do not have enough time to collect raw data by providing information compressed systematically in many academic information.

The purpose of this study is to review the symbolic meaning in 20th century men`s fashion through analyzing of social environment factors. After recent industrial society, men had expressed their privilege, prestige and social power according to fashion. Men`s fashion at the beginning of the 20th century was emerged as the images of robustness and strictness with perfect cutting, thick and stick fabric and dark color that were influenced by british style. It was symbolic meaning of authority orientation which showed the superiorities of social and sex classes. It was beginning of change according to social phenomena. The world war Ⅰ, Ⅱ and change of lifestyle by material affluence in automobile industry mollified rules of men`s fashion. It showed a serenity of living. Also, the growth of young culture changed trickle-down of men`s fashion into bottom-up and showed opposition for elite culture in fashion. These change particularly became acceleration by individualism, open-society and the collapse of sex class. Men expressed sexual and inherent desire for fashion that was no longer concerned with symbolizing of authority but rather with pleasure pursuit.

아이디어 발상 유형화를 통한 창의적 패션 디자인 전개 프로세스 연구

김윤경(Yoon Kyoung Kim),박혜원(Hye Won Park) 한국복식학회 2010 服飾 Vol.60 No.9

The purpose of this study is in allowing thinking about the design development process which is more towards the visual and perceptional aspects related to the form structure by more diverse methods by typology of idea generation. To accomplish such goal, researches in the psychology, pedagogy, engineering, and consilient studies as well as related precedent researches and reference data in architecture, promotion, industrial design, and other art fields and fashion designs are collected and analyzed to see the study trend. In addition, in the content analysis method based on such, the idea generation was classified into types in consideration of relevancy, usefulness, and suitability with fashion. First, a concentrated thinking of a limited space is a method of leading an optimal design by focusing on solving the cause of a problem within a space which generates the problem. Second, plan thinking per section of structure decomposition is a method of dismantling the design problems per organization, thinking type, factor, and characteristic into sub-modules to re-interpret and re-organize the problems in various aspects. Third, an associated thinking through interpreting relationships among vocabularies is a method of selecting the marginal languages that allow a person to come up with concrete forms and the key words related to fashion to import the characteristics and attributes of the marginal languages and thematic relationship between the two terms to search the relevancy. Lastly, the free integrated thinking of language extension is a method of groping integration between other fields and fashion by free integration among the extended terms by extending the vocabularies through inferring metaphorical expressions founded upon individual`s memories or knowledge concepts regarding theme words that do not allow concrete forms to come up.
