연관성 척도는 정보검색 및 데이터마이닝을 비롯한 다양한 분야에서 사용되고 있다. 각 연관성 척도가 높거나 낮은 빈도 중에서 어떤 쪽을 선호하는가를 나타내는 빈도수준 선호경향은 척도의 적용 결과에 중요한 영향을 미치므로 이에 대한 면밀한 조사가 필요하다. 이 연구에서는 주요 연관성 척도들의 빈도수준 선호경향을 가상의 데이터를 통해 분석하고 그 결과를 제시하였다. 또한 코사인 계수를 비롯한 대표적인 연관성 척도에 대해서 빈도수준 선호경향을 조절할 수 있는 방법을 제안하였다. 이 조절 방법을 동시출현 기반 질의확장 정보검색에 적용해본 결과 그 유용성이 확인되었다. 마지막으로 분석 및 실험 결과가 관련 분야에 시사하는 바를 논하였다.

The purpose of this study was to investigate the trends of product design for textile convergence wearable smart textile fashion products according to college students' fashion life style. In this study, we used information obtained from a questionnaire issued to 201 female college students who were 20 years old for the final analysis. The questionnaires were to classify female college students groups according to the fashion life style, to examine characteristics, needs and wants of each group. The survey on the tendency of wearable smart textiles consisted of 22 items about concept and type of smart clothing product, functional material and intelligent material, recognition, preference, purchase intention, purchase factor and brand preference tendency. A total of 201 samples were analyzed by factor analysis, cluster analysis, ANOVA, crosstabs and $x^2-test$ using SPSS package program. 'brand preference oriented type was found to be interested in 'wearable' smart clothing product with monitoring function of bio-signal' and 'high functional fiber and textile product', but the credibility of 'smart clothes that can be worn and smart textile products to be useful in modern life' was low. 'fashionable individuality oriented' type showed interest in 'smart clothing and smart product', 'intelligent fiber' and 'wearable smart clothing product with monitoring function of bio-signal', but the preferences of 'light emitting fiber products' was low. 'practically purchasing-oriented' type was very interested in 'high-functional fiber and its textile products', but had inadequate knowledge on 'smart clothing and smart textile product' and showed low interest. Despite the fact that 'wearable smart clothing and smart textile products' are expensive, they were willing to purchase considering practicality and sophisticated style.

The purpose of this study was to collect and analyze personal bio data and social network services (SNS) data, derive user preference and user life pattern, and propose intuitive and precise user modeling. This study not only tried to conduct eye tracking experiments using various smart devices to be the ground of the recommendation system considering the attribute of smart devices, but also derived classification preference by analyzing eye tracking data of collected bio data and SNS data. In addition, this study intended to combine and analyze preference of the common classification of the two types of data, derive final preference by each smart device, and based on user life pattern extracted from final preference and collected bio data (amount of activity, sleep), draw the similarity between users using Pearson correlation coefficient. Through derivation of preference considering the attribute of smart devices, it could be found that users would be influenced by smart devices. With user modeling using user behavior pattern, eye tracking, and user preference, this study tried to contribute to the research on the recommendation system that should precisely reflect user tendency.

This study examines the effect of structural properties of F/W wool knit fabrics for woman's knitwear on the preferences for textile designing through analyzing the relationship among the structural properties, mechanical properties, objective hand measurements, and preferences. The 'knit structure' was determined to be the most important parameter in rating preferences, apart from the 'preference for cardigans'. Consumers preferred washable wool to normal wool when comparing a normal wool knit with a washable wool knit on a 'knit structure' factor. Preferred structural properties showed a similar tendency 'preference for fabric' and the 'preference for cardigans', 'preference for sweaters' and 'preference for vests'. The 'sophisticated/feminine' factor showed a correlation with 'fabric preference' and the texture and sensible images had a similar effect on fabric preferences. In the relationship between objective hand measurements and fabric preferences, the KOSHI value had a negative coefficient and the THV value had a positive correlation with fabric preferences. In conclusion, we found a consumer preference for more flexible fabrics.

In this study Muffins adding each 0, 1, 3, 5 7% of Acai Berry powder, which has very high anti-oxidant constituent, have been made, and its quality characteristics have been surveyed. From the volume and specific volume measurement, it has been decreased for MA1, 1% of Acai Berry powder added muffin, but the tendency thereafter has shown increasing (p<0.001). From texture characteristics gumminess and chewiness of MA0, reference group, was the highest by 885.86 g/ cm and 6645.71 g, and has shown decreasing tendency as per the adding rate of Acai Berry powder increased (0.001). The electronics scavenging activity of MA7, 7% added muffin, was the highest by 68.91%, and the ascending order was MA1 < Reference Group < MA3 < MA5 < MA7. From the preference test of Acai Berry powder added muffin, MA3, 3% added muffin, was the most preferable one from color, taste as well as total preference. As the added volume of Acai Berry powder is 5% or more, the typical taste and flavor of Acai Berry gives influence to the taste and flavor of muffin, so the preference level has been decreased. Thus the added volume of Acai Berry powder 5% or more is not recommendable.

본 논문에서는 센서 네트워크를 이용하여 로봇 자신의 위치를 인식할 수 있는 위치인식 시스템을 제안하였다. 그리고 센서 네트워크에서 얻은 정보와 사용자의 운행 정보를 이용하여 사용자의 선호도 및 성향과 주변의 환경 상태를 판단하여 사용자에게 적합한 경로를 추천하는 지능형 네비게이션 시스템을 제안하였다. 이 시스템은 소프트 컴퓨팅 기법을 사용하여 인간의 선호도와 성향을 학습 및 추론하였다. 그리고 사용자와 모바일 로봇을 중계자 역할을 담당하고 휴대가 가능한 지능형 보조 모듈(IAM)을 정의하고 제안하였다. 마지막으로 제안한 알고리즘을 시뮬레이션을 통해 검증하였다.

그룹 추천은 개인이 아닌 그룹의 특성 및 성향을 분석하여 구성원들에게 적합한 정보를 제공하는 추천 방식이다. 기존의 그룹 추천 방식은 평균 선호도나 선호 횟수에 기반한 그룹 모델링 전략을 사용한다. 하지만 평균이 높고 선호 횟수가 많은 관심사더라도 선호도의 편차가 크다면, 그룹 내 구성원 모두를 만족시키는 추천 결과를 제공하기가 어렵다. 본 논문에서는 이를 개선하고자 관심사에 대한 평균 선호도에 선호도 편차를 가중치로 하는 그룹 모델링 전략을 제안한다. 제안하는 방법은 평균 선호도가 높으면서 선호도 편차가 작은 관심사들을 추천 결과로 제공해줌으로써 기존의 그룹 모델링 전략보다 더 많은 그룹 내 구성원들을 만족시키는 정보를 제공하는 것이 가능하다. 실험을 통해 제안하는 그룹 모델링 전략이 기존의 방식에 비해 높은 성능을 보였고, 소규모의 사용자뿐만 아니라 많은 수의 사용자가 형성하는 그룹에서도 높은 성능을 가짐을 확인하였다.
