인터넷상에서 고객들이 공연을 예약할 때에 대다수 예약 기법들은 고객들의 선호도를 고려하지 않고 예약이 이루어진다. 이러한 예약 기법들은 서비스 산업에서 중요한 고객들의 만족도를 향상시키기 어려운 문제점이 있다. 본 논문에서는 객체기반 스케줄링 기법을 공연예술 예약 문제에 적용하여 공연예술 예약 시에 일어날 수 있는 문제점을 해결하고자 하였다. 객체기반 공연예술 예약 스케줄링 기법은 객체지향개념을 기반으로 각 객체들이 가지고 있는 사건들을 주어진 제약들에 만족하도록 목표인 좌석배치도에 배정하는 기법이다. 각 객체들은 전체적인 만족도를 고려하면서 그 객체들의 우선순위에 따라서 자원을 배정하고, 자원에 대한 객체의 선호도 차이를 가질 수 있게 하였다. 클래스에 따라서 우선순위를 가진 객체들은 제약을 만족하면서 최선의 슬롯을 선택하여 사건을 배정한다. 사건의 배정이 실패하거나 백크래킹을 최소화하도록 전체 객체들의 만족도를 높이는 방향으로 스케줄링을 시행한다.

최근 개개인의 취향이나 특성을 고려하여 자동으로 사용자에게 정보를 찾아주거나 추천해주는 추천 서비스 시스템이 많이 개발되고 있다. 하지만 사용자의 상황에 따른 선호도를 고려하지 않을 경우 정확한 추천이 힘든 단점이 있다. 따라서 본 논문에서는 사용자의 상황에 따른 선호도를 고려하여 정확한 추천을 할 수 있는 필터링 방법을 제안하였다. 이를 위해 상황에 따른 사용자 선호도를 구하고 피어슨 상관계수를 이용하여 사용자의 상황별 오브젝트 선호도를 구하였다. 실험 결과, 기존의 서비스 시스템들과 비교하여 precision은 11%, 2%, recall은 8%, 4% 향상되었으며, 전체적으로 precision은 77%, recall은 53%로 나타났다.

The purposes of this study were to investigate preference and images of Korean traditional motifs, and to identify the relationship between them. The subjects consisted of 369 male and 356 female undergraduate students. The experimental materials used in this study were 48 stimuli and a questionnaire composed of 7-point semantic differential scales of 26 adjectives. Twelve motifs selected from 3 groups of Korean motifs were used as pattern design stimuli. Twelve repeated patterns were constructed from them to be applied on a CAD-simulated dress. The data were analyzed by ANOVA, Duncan's multiple range test, and regression. The major findings were as follows : 1. Category, composition type, and application object had a significant effect on the preference. Interpretation type has no significant effects on the preference independently, but it had interaction effects when combined with composition type, and category. Especially the composition type had a greater effect than the other variables on the preference. Cloud motif and its abstract and decorative type were found to be more related to the preference than the other category and interpretation type. On the basis of the analysis results, image charts and preference charts were developed. By combining information from the image chart and preference chart, motifs and images preferred by consumers may be selected and developed into new valuable designs. 2. The preference was affected mainly by 'quality'image followed by 'simplicity', 'interest', and 'modernity'image. The preference on pattern design was affected by 'quality', 'simplicity', 'interest', and 'interest', 'simplicity', and 'modernity'image in the order. The relationship between the preference and sensibility images has been represented by equations.

For a complex scheduling system like time table construction, its optimal solution, if exists, is hard to obtain. In this paper, the scheduling environment is reasonably confined as where objects have their own events competing for better slots on boards, and objects have their own board slot preferences and belong to one or more classes of the society which globally constrains them. Here, two phase method is suggested, where the first phase is human-like preference driven and the second phase is for fine tuning by considering all the factors given. Designed and implemented in our system HI-SCHED are dynamic object switching, temporal-constraint-driven intelligent backtracking, case-based revisions, object-based approach, and so on. Some satisfaction degrees are also defined to measure the usefulness of our method. In addition, look-ahead dynamic object switching is considered, and additional global constraints are introduced and processed. A simple scheme is also used to verify the usefulness of the post processing scheme.

본 연구에서는 제품의 선호도 평가를 위한 정보 탐색과정에서 영향을 미치는 요소에 대한 인지반응의 특성 파악을 기본 목적으로 하였다. 그리고 그 특성과 제품 선호도의 상관관계를 제품 사용 경험의 측면에서 고찰하였다. 이를 위하여, 휴대폰과 제안형 제품사진을 실험 자극으로 선정하여 두 단계의 실험을 진행하였다. 첫 번째 실험에서는 제시된 각 제품사진을 관찰한 후에 선호하는 순서를 정하여 배열하도록 하였다. 두 번째 실험에서는 앞에서 선정한 선호도 1순위와 10순위의 제품사진에 대하여 선호도 평가 시 최우선적으로 주목한 부분을 표시하고, 그 부분에 대하여 설명하도록 하였다. 실험 결과로부터 두 가지 결론이 도출되었다. 첫 번째, 제품의 사용 경험에 의한 경험적 기억 정보는 인지 대상의 선호도 평정(評定)에 있어, 그 인지 대상에 포함되어 있는 다양한 구성 요소에 대한 해석적 반응을 활성화한다. 두 번째, 제품의 비사용 경험은 선호도와 관계없이 인지 대상에 포함되어 있는 심미적 요소를 지각적으로 수용하는 반응을 유발한다.

복합 스케줄링 문제는 컴퓨터의 기획(planning), 스케줄링(scheduling), 제약만족문제(Constraint Satisfaction Problem, CSP), 객체지향개념(object-oriented concept), 에이전트 시스템(agent system) 등의 여러 분야와 관련이 있다. 사용자의 선호도를 고려한 기법은 제약만족문제와 객체지향개념을 스케줄링에 적용하여 복합 스케줄링 문제를 해결하고자 하였다. 본 논문은 사용자의 선호도를 고려한 기법을 예약 문제에 적용하여 예약 시에 일어날 수 있는 문제점들을 해결하고자 하였다 특히 고객들의 만족도를 놀이기 위해서 고객들의 선호도를 고려하여 스케줄링을 한다. 객체에 근거한 예약 스케줄링 기법은 객체 지향 개념을 기반으로 하여 라 객체들이 사건들을 가지고 있으며, 이 사건들을 주어진 제약들에 만족하도록 목표인 보드에 배정하는 기법이다 각 객체들은 전체적인 만족 도를 고려하면서 그 객체들의 우선순위에 따라서 자원을 배정하고, 자원에 대한 객체의 선호도 차이를 가질 수 있게 하였다. 예약 스케줄링을 할 때 제약은 전역 제약과 지 역 제약으로 구성된다. 보드에 대한 정의와 모든 사건들에 대한 정보를 전역 제약으로 사용하고, 각 객체가 가지는 보드의 슬롯들에 대한 선호도를 지역 제약으로 사용한다. 사건의 배정을 실패하지 않고 백크래킹을 최소화하도록 알을 보는(look-ahead) 백크래킹 기법을 사용하여 전체 객체들의 만족 도를 높였다.

The objectives of this study were to measure the preference and purchase intention on Korean traditional motifs and to investigate the relationship among preference, purchase intention, and sensibility. The subjects consisted of 217 male and 351 female US undergraduate students. The experimental materials used in this study were 48 stimuli and a questionnaire, composed of 7-point semantic differential scales of 17 bi-polar adjectives. The data were analyzed by ANOVA, Duncan's multiple range test, Regression, and t-test. The major findings were as follows; First, interpretation type and application object had significant effects on the preference, while category and interpretation type had significant effects on the purchase intension. The application of Korean traditional motifs for pattern design was preferred to their application for clothing design. Decorative type was found to be more related to the preference and purchase intention than the other interpretation types of realistic, stylized and abstract types. The purchase intention on crain motif was lower than the other categories of lotus and cloud motifs. Second, in overall, the preference on Korean traditional motifs was higher than purchase intention. Third, the preference and purchase intention were affected mainly by 'Quality' image, a component of sensibility, followed by 'Cheerfulness' image, but not affected by 'Simplicity' and 'Modernity' image.

Recent advancements in mobile device technology have enabled real-time positioning so that mobile patterns of people and favorable locations can be identified and related researches have become plentiful. One of the fields of research is the relationship between the object properties and the favored location to visit. The object properties of a person include personality, which is a major property jobs, income, gender, and age. In this study, we analyzed the relationship between the human personality and the preference of the location to visit. We used Spearman's Rank correlation coefficient, one of the many methods that can be used to determine the correlation between two variables. Instead of using actual data values, Spearman's Rank correlation coefficient deals with the ranks of the two data sets. In our research, the personality and the location data sets are used. Our personality data is ranked in five ranks and the location data is ranked in 8 ranks. Spearman's Rank correlation coefficient showed better results compared to Pearson linear correlation coefficient and Kendall rank correlation coefficient. Using Spearman's correlation coefficient, the degree of the relationship between the personality and the location preference is found to be 43%.

The objectives of this study were to investigate the effect of perceiver's fashion involvement, clothing color, and background of object person on image perceptions of clothing, and to examine how clothing color preference vary according to perceiver's fashion involvement. Subjects were 273 college women in the metropolitan area of Seoul. The T-shirt was changed into 11 colors by using the CAD system. Five factors were derived to account for the dimensions of image perception. These were individuality, elegance, femininity, activity, and neatness. Perceiver's fashion involvement gave a significant influence on perception of individuality. Clothing color gave significant influences on 5 image dimensions. White and beige were evaluated neat image. Neatness factor had an interaction effect by fashion involvement and clothing color. The high involvement group evaluated white and beige shirt more neatly, and orange and yellow less neatly than the low involvement group. Individuality and elegance had an interaction effect by fashion involvement and background of object person. The high involvement group liked red, violet, and black shirt more than the low involvement. Refined and becomingness image gave significant influences on clothing color preference in both high and low involvement groups.
