The purpose of this study was to analyze sensory evaluation, to assess visual serving size and plate waste estimates of daily menu, and the identify customer expectation, perception and satisfaction. Questionnaires of sensory evaluation, serving size and were waste were developed and hand-delivered to 2,520 people. A total of 2,255 questionnaires were usable: a 89.5% response rate. Customer satisfaction questionnaires were handed out to 700 customers: (100 each at seven operations). A total of 551 were returned completed (78.7%). The data was analyzed using the SAS package program for Descriptive Analysis, t-test and ANOVA. The result of sensory evaluation showed that 'taste' was 3.20, 'freshness' 3.17, 'temperature' 3.25, 'texture' 3.15, 'appearance' 3.12, 'overall evaluation' 3.21, so these were little higher than 「normal」, that is 3.0. There was positive correlation among 'taste', 'freshness', 'temperature', 'texture', 'appearance' and 'overall evaluation'(p<.001). Serving size score was 2.97 and plate waste was 4.87, thus plate waste percentage was about 22-33%. As the result of customer expectation, perception and satisfaction of menu quality, characteristics. Customer satisfaction was defined as the difference expectation and perception and customer perceptions in theis survey were lower than expectation, thus this result implied customers dissatisfied in all menu quality characteristics. IPA analysis showed that 'diversity of menu selection' and 'menu price' was included in A area 'Focus here'.
This paper suggests the necessity of design education to engineering majors through qualitative research on the characteristics of intelligent artifacts. Robot cleaner is one of intelligent artificial objects that can approach people's life without awkwardness. How do people think of robot cleaners and define their personality, these days? In this experiment, subjects use and observe four different robot cleaners that have different appearances, behaviors and sounds in an experimental setup where is similar to actual use environment. We measure subjects' preferences and assessments for four different robot cleaners' personality. The test subjects were 11 designers who frequently collaborated with engineers and were able to express and express opinions about products. Experimental results showed that robot cleaners with the highest scores in appearance, behavior, and sound had the highest preference. In contrast, robot cleaners with low scores in three factors showed different results in the preference ranking.

An integrated on-line inspection system was constructed with seven cameras, half mirrors to split images, 720 nm and 970 nm band pass filters, illumination chamber having several tungsten-halogen lamps, one main computer, one color frame grabber, two 4-channel multiplexors, and flat plate conveyer, etc., so that a total of seven images, that is, one color image from the top side of an apple and two B/W images from each side (top, right and left) could be captured and displayed on a computer monitor through the multiplexor. One of the two B/W images captured from each side is 720nm filter image and the other is 970nm. With this system an on-line grading software was developed to evaluate appearance quality. On-line test results to the Fuji apples that were manually fed on the conveyer showed that grading accuracies of the color, defective and shape were 95.3%, 86% and 91%, respectively. Grading time was 0.35 sec per apple on an average. Therefore, this on-line grading system could be used for inspection of the final products produced from an apple sorting system.
Glutinous rice dduk, traditional Korean rice cake, was prepared using rice(white glutinous rice, brown glutinous rice, black glutinous rice, gaba glutinous rice) as a meal alternative, and each of their quality characteristics were compared. This study had checked sensory tests, color differences, moisture contents, texture characteristics, and storage lives of dduk during storage at room temperature for 6 days. The moisture contents of black glutinous rice dduk scored the highest. For color properties, gaba glutinous rice dduk was darker with a decreased yellow value, whereas its red value was higher comparing with that of brown glutinous rice dduk. The results of the preference test showed that appearance, flavor, texture, and overall preference were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the lowest score. The results of the color difference test showed that softness, viscoelasticity, and fineness were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the highest difference in color. For individual textural characteristics, black glutinous rice dduk showed the highest score, whereas white glutinous rice dduk showed the lowest scores in hardness, chewiness, and gumminess. In the results of the textural characteristics of dduk during storage, white glutinous rice dduk showed the highest increase in hardness after 48 hours, whereas black glutinous rice dduk showed the lowest increase. White glutinous rice dduk showed the highest increases in chewiness and gumminess. Cohesiveness decreased in all glutinous rice dduk. In the results of fungal occurrence in dduk during storage, black and gaba glutinous rice dduk showed increased fungi occurrence compared with white and brown glutinous rice dduk after 6 days. In conclusion, the overall preference for glutinous rice dduk made from different rice is more affected by appearance or texture than flavor.
The purpose of this study is to propose changes that can be made to improve nurse uniforms in terms of outfit and functionality based on actual wearing conditions and nurse's preference. The proposed nurse uniform was composed of a blouse and pants. The design was as follows: the blouse had short set-in sleeve with China collar, a princess line, and it came down to middle hip. Armhole action pleats and back inverted pleats were embedded for convenient arm movements. The pants waist had a rubber band at the back waist, and the crotch length and the knee width were increased for activity. To make the pocket more accommodative, separate pocket slots treated with silicone were added to prevent belongings from coming out of the pocket. The pink tone of the uniforms, as well as the stripes on the blouses and spandex incorporated pants were based on nurses' preference. the nurse uniforms were produced after measuring the size of women in the age of 25 to 29, and the uniform patterns were corrected after two wearing experiments. Wearing test was examined in terms of appearance and functionality. For appearance, experts gave the uniforms a mean rating of 4.30, and nurses gave a mean rating of 4.00. Functionality was evaluated in terms of ease of activity and storage aspects. The total mean of ease of activity in nursing service was 4.30, whereas the evaluation of storage in terms of pocket position and convenience was 3.80.
This study of a music therapy program for the 18 subjects residing in Jeollanam-do province was conducted two times per week during 4 months totalling 17 times in order to evaluate the reduction of the characteristics of patients suffering from stress disorder patients such as depression, and anxiety, Though the experiment for non-symmetric level the concentration and appearance of Alpha wave were determine to be stable but the findings from non-symmetric level according to the left-right brain activity were not significant for T-test, though its effective intermission of music therapy due to variation of the mean values was demonstrated, and the variation of the Alpha wave appearance rate was also significant for the statistics of the T-test for the effectiveness of the music therapy. And for the reduction of depression, emotion, and state-trait anxiety between groups divided into the control group and the experiment, pre-measurement and post-measurement comparisons through psychological tess, validated the effectiveness of music therapy for Posttraumatic stress disorder patients. First of all, this study was conducted in the situation of scarce study cases and program developments for the efficacy of music therapy for the patients suffering from Posttraumatic stress disorders without precedent studies of scientific identification through brain wave measurement. Because this study is insightful in the context of validating the efficacy of musical treatment, we expect that these kinds of studises will be continued.
The development of foundation garment pattern on the typical adult women's body was carried out. By means of the flatted body surface shell, the foundation garment pattern was developed. And its fitting test also performed. The results of this study can be summarized as follows; 1. The investigated Foundation basic pattern was made by the allowing the maximum bust size without any surplus since it was based on the tight-fitted model drawing technique. The investigated the completed pattern was designed in three parts of front and back body, including bust. 2. The result showed by overlapping the torso basic pattern foundation and body surface development selected from body almost the same except for the shift of dart position. 3. The result by overlapping basic pattern 3 existing basic patterns. On the basis of top-bust line showed that the setting up the volume of dart of bust and its waist affect the appearance of model. Especially, it was found that the above result was related to the bust and under bust line. 4. The result of the wearing test of 3 existing basic patterns and basic pattern of this study revealed that the mean values of whole items were higher than average in type P and type E. The fitting & position of under-bust line and extent of wrapping bust showed the high points in the current study and type of P. The result of evaluating the whole appearance in three points(front, side, back) showed different according to the every basic foundation garment pattern.
This study is about consumer preference of plastic toilets that can provide automatic supply of recycled water. First, the preference for plastic toilet seat design by gender and age group was preferred for gender type C and G for the sex. As the result of the chi-square test, the significance probability is .044 and the significance is P <.0 5. I could confirm that. Age, teens, 40 s, and 50 s or older prefer type C, 20 s and 30 s, but B type is not statistically significant. Second, the differences among the groups of preference for appearance design criteria according to general characteristics were all stable (stable appearance) in gender, age, region, education, and salary, but the chi-square test showed that they were not statistically significant. There was no difference between them. This study has implications for improving competitiveness and productivity by reducing the main production cost by commercializing toilets made of plastic materials.
Purpose: The objective of this study is to find the differentiating characteristics of ameloblastomas and odontogenic keratocysts of the jaw by analyzing computed tomography (CT) images of the lesions, clarify radiological characteristics associated with jaw lesions, and to make a diagnsis based on these findings. Materials and Methods : Test subjects were chosen among the patients who were diagnosed as having an odontogenic keratocyst or ameloblastoma at the Yonsei University Dental Hospital from January 1996 to December 2000 and had CT scans taken preoperatively. The subject pool was comprised of 51 cases of odontogenic keratocyst and 37 cases of ameloblastoma. The following measures were used for image analysis of the lesion: the anatomic location, CT pattern, mesiodistal width, buccolingual width, the ratios between mesiodistal width and buccolingual width, height, CT number, homogeneity of radiodensity, the appearance of a sclerotic rim, continuity of adjacent cortical bone, and displacement and resorption of adjacent teeth. Results: Comparing the CT patten, mesiodistal width, buccolingual width, height, CT number, homogeneity, appearance of sclerotic rim, continuity of adjacent cortical bone, there were statistically significant differences between ameloblastoma and odontogenic keratocyst test subjects (p<0.05). Comparing the ratios between mesiodistal width and buccolingual width, displacement and resorption of adjacent teeth, there were no statistically significant differences (p>0.05). Conclusion: We compared odontogenic keratocysts and ameloblastomas in CT scans. They occurred most frequently in the posterior to the ramus of the mandible. The findings of patterns of the CT images showed that size and border of lesions were more aggressive in ameloblastomas than in odontogenic keratocysts. The internal contents represented an increased attenuation area (IAA) in odontopenic keratocyst. Odontogenic keratocysts were shown to have higher CT numbers than ameloblastomas.

This study identifies the dimensions of cosmetics consumption values and the differences in cosmetics brand selection through a cosmetics consumption value group and by product type. The subjects of the study were females over age 20 living in Seoul and Gyeonggi Province between January and February 2008; 427 questionnaires were used for analysis. For data analysis the SPSS 17.0 statistical program was used, and principal component analysis, factor analysis using Varimax rotation, Cronbach's ${\alpha}$ reliability testing, cluster analysis, ANOVA test, and Duncan test were conducted. The results and conclusions of this study are as follows. The dimensions of cosmetics consumption values were found to be the pleasure value, the fashion value, the function value, the brand ostentation value, and the appearance ostentation value. Five types of groups by factor were identified: the group seeking function, the group seeking fashion and brand ostentation, the group seeking pleasure, the group seeking appearance and brand ostentation, and the indifferent group. Second, The group attaching importance to functionality was more likely to select high-priced brands while the group attaching importance to brand awareness were more likely to seek foreign brands, irrespective of product type. As far as base and color cosmetics are concerned, the group attaching importance to pleasure was more likely to select low, medium, and high priced foreign brands, as well as low and medium priced domestic brands. As for body products, the group attaching importance to fashion and brand awareness tended to select low, medium, and high priced domestic brands, as well as high priced foreign brands. By simultaneously purchasing high, medium, and low priced brands, these groups display an ambivalent consumption pattern. This study identified the differing dimensions around cosmetics consumption values and cosmetic brand selection. The research findings helps cosmetic companies set product prices and contributes to cosmetic marketing strategies.
