The purpose of this study was to survey a preference to the esthetic profile between Korean women and Korean American women. The interviewee were consisted of 30 Korean women and 30 Korean American women respectively. The survey has been done by using questionnaire. Altered facial profile of each normal male and female was got by moving maxilla, mandible to the front and back to survey the preference among the various profile. Then results were analyzed by SPSS program. The results were as follows, 1. In Korean women, in choosing the men's profile, 9 people out of 30, picked the standard profile as a most preferred profile, and bimaxillary retrusion and bimaxillary protrusion profile were followed by 6 people and 5people respectively. 2. In Korean American women, in choosing the men's profile, the 18 people out of 30, pick the bimaxillary retruded profile as a most preferred profile, and the standard profile were followed. 3. In Korean women, in choosing the women's profile, 18 people out of 30, picked the bimaxillary retruded profile as a most beautiful profile, and standard profile were followed by having 10people's voting. 4. In Korean American women, in choosing the women's profile, the 14 people out of 30, chose the bimaxillary retruded profile as a best one and the standard profile were followed by 12 people's voting. The preference of men's profile was significantly different between two groups (p<0.05) but the both group picked the bimaxillary retruded profile as a most beautiful when they choose the women's profile and then there was no statistical difference between the groups.

This paper proposes a technique of user oriented document ranking using user refile to provide more satisfied results which reflect preference of specific users. User profile is constructed to represent his or her preference. User pfofile consists of 'term array' and 'preference vector' according to the interest field of one. And the User profile for a particular person is updated by 'user access', 'latent relaeon', 'User Profile' proposed in this paper. The latent structures of documents in same domain are analysed by singular value decomposition(SVD). Then, the rank of documents is determined by comparison of user profile with analyzed document on the basis of relevance.

Collaborative filtering systems based on ｛user-document｝ matrix are effective in recommending web documents to user. But they have a shortcoming of decreasing the accuracy of recommendations by the first rater problem and the sparsity. This paper proposes the automatic preference rating method that generates user profile to solve the shortcoming. The profile in this paper is content-based collaborative user profile. The content-based collaborative user profile is generated by combining a content-based user profile with a collaborative user profile by mutual information method. Collaborative user profile is based on ｛user-document｝ matrix in collaborative filtering system, thus, content-based user profile is generated by relevance feedback in content-based filtering systems. After normalizing combined content-based collaborative user profiles, it automatically rates user preference by reflecting normalized profile in ｛user-document｝matrix of collaborative filtering systems. We evaluated our method on a large database of user ratings for web document and it was certified that was more efficient than existent methods.

The purpose of this study was to determine the level of perception and preference between dentists and lay people to altered facial profile. The assessors consisted of 40 dentists and 54 lay people, the survey was performed using questionnaire asking the order of perception and preference. The profiles presented in the questionnaire were based on the profile of one man and one woman, each morphed according to anterior or posterior direction of maxilla and mandible. The results were as follows. 1. In antero-posterior change of man and woman s profile, both dentists and lay people were sensitive to relatively skeletal profile (convex profile) changes than skeletal profile (concave profile) changes. 2. At least dentists needed to be perceived a 2 mm change in convex profile and a 3 mm change in concave profile and lay people needed to be perceived a 2 mm change in convex profile and a 3 mm change in concave profile for profile view. 3. Dentists are more sensitive in perception of man s profile change than lay people, but there is no significant differences between dentists and lay people in sensitivity of detection for woman s profile changes . 4. It seems that there is a general concordance between dentists and lay people in there perception of man s and woman s facial profile. This information might be clinician in comprehensive perception and preference of dentists and lay people to altered facial profile.

The information system in which users can utilize to control and to get the filtered information efficiently has appeared. Content-based filtering can reflect content information, and it provides recommendation by comparing the feature information about item and the profile of preference. This has the shortcoming of the varying accuracy of prediction depending on teaming method. This paper suggests the discovery of preference through learning the profile for the content-based filtering. This study improves the accuracy of recommendation through learning the profile according to granting the preference of 6 levels to estimated value in order to solve the problem. Finally, to evaluate the performance of the proposed method, this study applies to MovieLens dataset, and it is compared with the performance of previous studies.

본격적인 디지털 데이터 방송 시대를 맞이하여 TV는 다양하고 인터랙티브한 서비스의 제공이 가능해 졌다. 디지털 TV의 데이터 서비스는 매우 다양하다. 그 중 Electronic Program Guide(EPG)는 가장 기초가 되는 서비스이다. EPG의 아키텍쳐를 설계하기에 앞서 TV 프로그램에 대한 분류와 데이터 베이스화가 선행되어야 하며 이렇게 만들어진 Program Content Profile(PCP)와 사용자가 설정해 준 후 자동으로 갱신되는 User Preference Profile (UPP)는 EPG 어플리케이션의 스마트 기능 중 하나인 방송 프로그램 추천 기능을 가능케 해주며, 그 외에도 여러 스마트 기능들을 구현하는 중요한 척도이다. 본 논문은 이러한 모든 아키텍쳐를 시험적으로 설계 구현하였으며 그 예를 보여준다.

The purpose of this study was to investigate the relationship between personality and color preference, thereby to suggest a personality profile on the basis of colors selected for children's preference. Materias used to determine the degree of color preference were 24 color papers which were developed and described in a previous research by Lee & Lee. The Instrument used ot determine children's personality was Burks' Behavior Rating Scales-Preschool and Kindergarten Edition. Subjects wee 70 3-, 4- and 5- year old children attending the Y Child Development research institute. Data were analyzed with SPSS using mainly F-test and Duncan's Multiple Range Test. Results showed that among 24 colors used, white, violet, sapphire, sky blue, blue, green yellow, pink, green, red, gold, purple, van dyke brown, blue, green, silver were found to be significantly related to persionality. Judging from this results, white and violet seemed to be most predictive colors to personality. Personality aspects significantly related to specific colors were discussed and a profile of personality based on color preference were developed.

Nowadays, the user-centric application based web 2.0 has replaced the web 1.0. The users gain and provide information by interactive network applications. As a result, traditional approaches that only extract and analyze users' local document operating behavior and network browsing behavior to build the users' preference profile cannot fully reflect their interests. Therefore this paper proposed a preference analysis and indicating approach based on the users' communication information from MicroBlog, such as reading, forwarding and @ behavior, and using the improved PersonalRank method to analyze the importance of a user to other users in the network and based on the users' communication behavior to update the weight of the items in the user preference. Simulation result shows that our proposed method outperforms the ontology model, TREC model, and the category model in terms of 11SPR value.

Soft tissue profile is a critical area of interest in the development of an orthodontic treatment and diagnosis. The purpose of this study was to determine the facial profile preference of diversified group and to investigate the relationship between most Preferred facial Profile and existing soft tissue reference lines. A survey instrument of constructed facial silhouettes was evaluated by 894 lay person. The silhouettes had varied nose, lips, chin and soft tissue subnasale point. Seven sets of facial type were computer-generated by an orthodontist to represent distinct facial types. The varied facial profiles were graded on the basis of most preferred to least preferred. Every facial profile were measured by soft tissue reference lines(Ricketts E-line, Burstone B-line) to observe the most preferred facial profile. The results as follows: 1. In reliability test, the childhood group showed lower value than other groups, which means that this group has no concern on facial profile preference. 2. It appears that sexual and age difference made no significant difference in selecting the profile 3. An agreement to least preferred facial profile was higher than an agreement to most preferred facial profile. 4. Coefficient of concordance (Kendall W) was higher in the twentieth group. It means that a profile preference of the twentieth is distinct. 5. A lip protrusion (to Ricketts E-line and Burstone B-line) of most preferred facial profile was similar to measurements of previous study that investigate skeletal and soft tissue of esthetic facial profile of young Korean. So these reference lines can be used valuably in clinics. 6. Profile of excessive lip protrusion or retrusion to E-line & B-line was least preferred. 7. Most preferred profile of all respondents group was straight profile. Profile that showing convex profile was not pre(erred and the least preferred profile was concave profile.
