In this study, aesthetic impressions were used for a high-level feature of image retrieval. The term, 'aesthetic' has been studied in psychology, art, and literature. It means unconscious, instantaneous parts of visual perception and emotion. The literatures related to aesthetic impressions were reviewed and four kinds of aesthetic impressions were defined operationally : strong impression, soft impression, courteous impression, and refined impression. 66 image files of paintings were sampled randomly from 1100 paintings and low-level color features were extracted from them by a using perceptual color model(Lai, & Tait, 1998). The high-level features of an image, that is, four kinds of aesthetic impressions of each painting were measured by 4 subjects and averaged. In CBIR, 2 subjects performed image retrievals using example queries. They were asked to retrieve images by using the aesthetic impressions or the keywords. In evaluations, subjects showed that they were satisfied with the aesthetic impression-based image retrieval system on the average. And R-precision of the image retrieval with both color features and aesthetic impressions was higher than that of the image retrieval with color features only. But further studies with larger test collections and query sets should be followed for generalization of the result of this study.

The purpose of this study is to know what impression management(IM) tactics social work applicants use in their job interviews and what relation between their IM tactics and interviewers' evaluation exists. To accomplish this purpose, we reviewed the precedent researches about IM and conducted a qualitative study with the applicants in a community welfare center which adopted open approach in recruitment process. We analyzed the applicants' IM tactics through observing video-taped interview sessions and reviewing interviewers' rating paper. The results showed that the social work applicants mainly used self-promotion tactic for emphasizing their strengths and justification tactics for expressing their weaknesses. Some applicants often used fit-with-organization and other-enhancement belonged to ingratiation tactics. According to interviewers' rating results, the applicants with deep eye contact, calm attitude or smiling face gave a good impression to the interviewers. In the final discussion, an applicant who adopted diverse verbal and non-verbal tactics and expressed her point clearly was perceived attractive by the interviewers and accepted as the best choice. Based on this qualitative analysis, we have made several practical suggestions for social work applicants, social work researchers and social work organizations.

The characteristics of dental treatment makes the dental staff frequently contact with patient directly. Also the daily use of high-handpieces, sharp instruments, and needles often causes bleeding on oral cavity. Therefore, the risk of cross transmission grows up. The pathogen from dental practice could spread on not only the practice itself but also the dental laboratory with contaminated impressions and prosthesis. Dental clinic staffs (dentists, dental hygienists and dental technicians) should recognize all the patients have a possibility of cross contamination, and try to prevent the transmission of infection by proper infection control. In this study, we review the articles about disinfection methods and chemical infection agents used for dental impressions, and try to figure out the suitable and effective infection control system of dental impressions.

In conclusion, the systemic environment was shown that negative environment was being created to deepen conflict, and the conflict processes could be changed in either positive or negative directions by the psychological environment and psychological resolution mechanisms proposed afterward. As the result that the psychological environment was improved into aggressive mood with constant communication effort with the interested parties, the psychological resolution mechanism was also presented in the suitable forms of aggressive communication. On the contrary, if developed psychologically negative environment, the psychological resolution mechanism was also negatively affecting the conflict processes with dogmatic and consistent response rather than flexible response suitable to the situations.

전국 176개 지자체의 5개년 자료를 이용하여 생활용수의 가격탄력성을 분석 하였다. 기존의 연구에 비해 상대적으로 낮은 결과가 도출되었다. 수도요금 10% 인상에 수요량은 0.5% 감소하는 것으로 나타났다. 따라서 수도요금 인상을 통해 수요량 절감을 달성할 수 있을지 여부는 불투명해 보인다. 따라서 탄력성이 있다는 결론이 자칫 수돗물 값을 몇 % 인상시키면 댐 몇 개가 필요 없다는 식의 논리는 위험한 생각이다. 물 값의 역할은 물수요 절감뿐 아니라 향후 공급에 요구되는 비용의 회복과 시설의 효과적인 유지 및 관리비용임을 명심해야 한다. 국가 정책의 수립을 위해서는 정상적인 가격체계의 도입과 함께 보다 객관적인 연구가 요구된다.
