The purpose of this study was to evaluate the reproducing accuracy of stone casts made from complete arch impressions using different impression materials. The impression materials studied were 1) polyether, 2) polysulfide, 3) polyvinyl siloxane, and 4) irreversible hydrocolloid. Impressions were made from a partially edentulous acrylic resin model with metal inserts in canine, first molar region bilaterally and mid palatal vault region. Each distance between 2 out of 5 meauring points was measured by using 3dimensional measuring machine. Impressions were poured at once with a type IV dental stone. Data were analyzed using t-test with a sample size of six. The results were as follow : 1. Polysulfide and polyether were significantly superior to polyvinyl siloxane and irreversible hydrocolloid in reproducing full arch model(p<0.05), but there were no statistical differences in amount of dimensional reproducing accuracy for full arch impression between polysulfide and polyether(p>0.05). 2. There were statistical differences in amount of dimensional reproducing accuracy between edentulous area and tooth bound area for polysulfide and polyether(p<0.05). but no statistical differences were observed for polyvinyl siloxane and irreversible hydrocolloid(p>0.05).

The purpose of this study is to investigate the effect of hair-style (straight and wave), hair-length(short, medium, and long), and type of hat design (no-hat, beret, cloche, bowler, and capeline) on impression formation. The experimental materials developed for this study were a set of stimulus and response scales. The 7-point semantic differential response scales were designed. Thirty stimuli color pictures of various combination of hair length, hair style, and type of hat design were manipulated by computer drawing. The subjects were 360 undergraduates living in Seoul, Kyunggi and Kyungnam. The experimental design was composed of 3 factorial designs. The result of the study can be summarized as follows; Impression factor of the stimulus consisted of the 5 different dimensions (attractiveness, gracefulness, activity, concentration of attention, cuteness). Hair style greatly affected gracefulness. On the other hand, hair length made remarkable effects on attractiveness, concentration of attention, and cuteness. In addition, it has been found that the type of hat design significantly influenced on all the factors except attractiveness as independent variables. In regarding the effect of interaction between each variable, the combination of hair style and hair length had significant effects on gracefulness. In the impression formation of cuteness, the combination of hair length and type of hat design were more significant.

This study examines the effects of clothing style and the order effect on impression formation. The instrument of this study consisted of response scales and stimuli. Fifty-one items of 7-point semantic differential scales, 9 items of demographic traits, and 4 items of subjective evaluation scales were developed. Stimuli were color pictures of a model wearing each of two clothing styles(mannish style, feminine style). The sample include 56 male and female subjects in their twenties and thirties. The experimental design was within-subject design and the half of the sample responded to the mannish style first and the other half responded to the feminine style first. Responses to the semantic differential scales were factor analyzed, and seven factors were identified: intellectuality, sensibility, activity, modesty, competence, display, keenness. There were significant differences between mannish style and feminine style in impression of wearer＇s age, job, and physical attractiveness as well as wearer＇s intellectuality and sensibility. It was revealed that the first impression and second impression of wearer＇s intellectuality, sensibility, modesty, competence, display were differed by the function of the order of stimuli shown to the subjects. Both primacy effect and recency effect of order effect were confirmed, and especially negativity effect was influenced prominently on impression formation.

Purpose: Current common method of cytotoxicity evaluation for elastomeric impression materials use animal based cell lines, which the clinical relevance has been often questioned. Hence, the purpose of this study was to examine the difference in results with both human based and animal based fibroblast cell line. Materials and Methods: Three types of fibroblast cells were used in this study; conventional mouse fibroblasts of L929, human gingival fibroblasts (HGF-1), and immortalized human oral fibrobalsts (hTERT-hNOF). Test on extract and test by direct contact using different commercially available elastomeric impression materials were carried out according to the international standards. Result: There was significant difference in cell viability between types of fibroblasts cell used, where HGF-1 showed highest cell viability and L929 the lowest. Conclusion: Within the limitation of this study, careful consideration must be given when selecting the cells and interpreting the results for cytotoxicity evaluation of elastomeric impression materials, where use of human based cell lines such as hTERT-hNOF would be appropriate for both ease of cytotoxicity test and clinical relevance.

In this study, the wettability and mechanical properties of silicone rubber impression material were studied by using precipitated silica and fumed silica with different particle size and polarity (hydrophilic/hydrophobic). Curing time of impression material depended on the particle size of fumed silica. The curing time delayed about 9 minutes by using A300, which was the fumed silica with the smallest particle size among the silica used in this study. Wettability of rubber impression material improved with the introduction oi hydrophobic fumed silica(R972). Also, the optimum flow and mechanical properties could be obtained by using blended silica with the 90: 10 ratio of precipitated and fumed silica.

The purpose of this study was to investigate 1) the effects of clothing styles on impression formation of middle and high school students and 2) the differences in impression in relation to perceiver variablex(sex, age, residence). The sample consisted of 60 subjects in each of 8 perceiver groups according to sex, age and residence. Stimuli consisted of 10 color photographs of male and female adolescent wearing each of 5 clothing styles respectively. Questionnaires consisted of 43 seven-point semantic differential scales measuring perceivers responses to the stimuli, open-ended Question and perceiver’s clothing style preference. Responses to the semantic differential scale were factor analyzed and 4 factors - Self-confidence/refinement, Sincerity, Intelligence, and Sociability - were emerged to account for the structure of the impression of the male stimuli. Five factors - Sincerity, Refinement, Self-confidence, Sociability, Intellience - were emerged in case of female stimuli. One-way ANOVA results showed that clothing styles had the effects on all the factors of impression except Sincerity. From the reset analyzing the effects of perceiver variables on impressions, age had the effects in all the clothing styles, sex had the effects in 6 clothing styles, and residence in 5 clothing styles. Clothing style 5(male stimuli) and style 10(female stimuli) were the most preferred clothing style in all the subject groups.

This study investigated the time-dependent dimensional changes of elastomeric impression materials using holographic interferometry. Six commercial impression materials, Permlastic(polysulfide), Xantopren VL (condensation silicone), low and medium viscosity of Exafine, Provil (addition silicone), and Impregum(polyether), were selected. Steel plate was used as custom tray, and each impression specimen was 20 mm in width, 15 mm in length and 3 mm in thickness. Each impression material was evaluated at 30 minutes, 1, 2, 4, 6, 8 and 12 hours after setting using real-time holography. The results were as follow : 1. Xantopren VL and Permlastic showed relatively severe and continuous dimensional changes after setting. Low viscosity of Exafine, Provil, Impregum showed relatively slight dimensional changes with function of time and medium viscosity of Exafine showed almost no dimensional change from 2 hours after setting to 6 hours. 2. On initial dimensional changes within 1 hour, the amount of change in low viscosity of Exafine was the least and Xantopren VL was the largest. 3. On dimensional changes at 4 hours after setting, the amount of change in medium viscosity of Exafine was the least and tile change of Xantopren VL was the largest. 4. In overall dimensional stability during 12 hours, medium viscosity of Exafine was the most stable and Xantopren VL and Permlastic were least stable.

Consumers can have impression goals as well as defense goals. Those with impression goals could use social goals or opinions of others in a social context to determine their attitudes, and those with defense goals could maintain their existing attitudes and beliefs. Since people typically approach pleasure and avoid pain, there are two kinds of goal orientations depending on regulatory focus theory. Therefore, marketers could design advertisements for their products on the basis of two types of focus, promotion-focused and prevention-focused advertisements. This study aims to explore how consumers with different consumption goals evaluate an advertised product. The results of this study demonstrate that consumers with impression goals felt much more "right" about the product in a promotion-focused, rather than prevention-focused, advertisement, and those with defense goals, felt much more "right" about the product in a prevention-focused advertisement. Consumers with impression goals evaluated the product in the promotion-focused advertisement more favorably than in the prevention-focused advertisement, and those with defense goals evaluated the product in the prevention-focused advertisement more favorably.
