This stusy was to investigate the marginal fitness of porcelain-fused-to- metal crown after succesive firing cycle. Main variables were the degree of marginal curvature of labiocervical margin and the type of alloy. The exaggerated marginal curvature(EMC) was created by additional reduction at the faciocervical wall of the normallized marginal curvature (NMC)-typed ivorine tooth by using milling machine. The difference in the shape was the mid facial margin was placed 2mm apical to cemento- enamel junction in labial surface. Three types of alloy were high noble, noble, and base metal alloy. Test specimens were divided into 8 groups and each group had 8 specimens. Sixty four ceramometal crowns were made totally. Measurement stages were following degassing, opaquing. body porcelain firing, and glazing, and measuring sites were 4. (midmesial, midfacial, middistal, and midlingual). Digital, travelling measuring microscope (0.5 um precision, Olympus. Japan) was used under ${\times}250$ magnification. Within the limitation of this investigation, it was concluded as belows: 1. The pattern of marginal distortion was varied. Degassing stage was not a specific, causative stage that induce most of total marginal distortion during whole procedure fabricating a ceramometal crown. Body firing stage induced discrepancy relatively more than other firing stages. 2. The specimens that were Ni-based alloy and had EMC were distorted persistently following successive fabricating procedures. But marginal openings were decreased after glazing. 3. The release of metal grinding-induced stress was presumed as a cause that induce marginal distortion. 4. The amount of discrepancies of the labial and lingual margins were greater than that of the mesial and distal margin in the specimen that had EMC. 5. Silver-plated die was not enough to resist abrasion during repeated seating of metal copings on the die-holding device.
The BSC which was proposed by Kaplan and Norton, is being used as a general performance measurement tool in various firms and industries. BSC approach links strategic objectives with specific operation indices and it can efficiently evaluate the attainment of the goals of the firm. This study is a BSC based case of the government R&D institute which is staffed with knowledge experts in the research areas. In order to bring a major change to a public research organization and shape a strategy focused organization, it is essential to understand the proper methodology of the whole construction process of BSC from the mission of the institute through the establishment of vision and strategic direction, KPI building, and a strategy map set, to the implementation of the BSC monitoring system. By investigating the application process, in this research we intend to provides useful implications in the BSC construction process of public research agencies.
Clothing must have the individual beauty and the function that one can do one's body movement freely. therefore, from the human engineering view point, the exact measurement of the human body and the analysis of it's results must be applied to clothing because the arm works most. In this study, the skin surface of arm was investigated by shell made of Alginate of each movement. And by sometic method the rate of expansion and contraction of each section, inter-relation among the bust girth, axillary arm girth and scye girth and between the shoulder length right and the under axilla waist length were calculate4d. With these results, cap height, breadth of a sleeve and arm hole girth of existing sleeve pattern have been compared and analysed. The results are as follows; 1) According to the developmental figures of shell, the whole area change was small but that of shape was remarkable in M 4, 9, 13. The change of the Block 1 was particular. 2) Over arm length was contracted in all movements except M6 and under arm length expanded. The changes of sections a, b, c are large, while those of sections d, e are small. 3) In terms of latitudes, change of fore-arm region was small. The rate of scye girth varied from 14.3% of M13 to-5.6% of M2. The breadth of a sleeve expanded in all movements, and especially the front region expanded more than the back. 4) The relation between the shoulder length right and under axilla waist length, in all occasions, was contracted mutually, and one contracted, the other expanded. Therefore, in clothing construction when we consider the function of the arm it is better to widen the arm hole and the breadth of a sleeve at the same time than no widen the shoulder length by lowering the upper part of the upper side seam line.

This study was designed to propose a method to draft bodice block pattern from 3D body scan data. Subjects were ten elderly women in their 60's, who wear basic size(B: 94cm, W: 82cm) garment. Scanning was done using 3D whole body scanner(WB4, Cyberware). Measurements for 3D data and cross section were attained using Auto CAD, by which a upper bodice pattern for elderly women was drawn on the basis of short measured method. The results are as following: As for most items, no significant differences were shown between measurements from Martin's anthropometry and those from 3D scan data, suggesting measurement from 3D scan data could be used to draft a pattern. The drafting equations acquired were as follows; width of pattern=B/2+5.5, width of waist=W/2+3.5cm, dart amount=8cm. Dart distributions were 23%(B.P.) : 20%(front armpit) : 17%(side seam) : 18%(back armpit) : 15%(back protruded point) : 7% (center back line). Through wearing test using 5-point Likert scale, resultant pattern was evaluated as appropriate for elderly women's pattern to get over 4 point. As a result, it might be said that 3D scanning application is effective for elderly women in that it doesn't take time so much as Martin's anthropometry and that their body shape vary compared with those of young women.
The purpose of this study was to research on breast shape and size to suggest a brassiere sizing chart for elderly women. For this purpose 90 elderly women aged between 55 and 69 were sampled at random to review their breast types by age group, and thereby, suggest the basic measurements and production ratio of each brassiere size in reference to KS K 0070: 1999. The collected measurement data were processed statistically using the SPSS PC/WIN program for technical statistical analysis. The results of this study can be summarized as follows; 1. Analysis of Breast Measurements To find out difference among age groups, the 90 subjects were grouped into three(Group 1 ; aged 55 to 59, Group 2 ; aged 60 to 64, Group 3 ; aged 65 to 69). The results of the comparative analysis of anthropometric data from three groups show that getting older;- Various length measurements related to the drooping degree of breast were increased. It was found that the older group in their 65-69's had more drooping breasts than their 55-59's or 60-64's counterparts. Such findings suggests that older women's drooping can be corrected by a brassiere which serves to support the breasts. 2. Suggestions on a Brassiere Sizing For the basic measurements of brassiere parts for the elderly women, the correlation between underchest circumferences and cup sizes were analyzed. 3% or higher occurrences among the whole sample elderly women were included in the brassiere sizes. thus, the under-chest measurements were set at four intervals from 75 to 95, while the cup measurements were determined also at four intervals from "AAA" to "B" sizes. The resultant 6 sizes excluding the least frequent occurrences covered 73.2% of the sample elderly women actual breast sizes. As a consequence of reviewing the production ratio of each brassiere size for the women, it was found that the brassiere size of highest production ratio was "85A" (17.4%), followed by 80A (14.5%), 85AA 90A (10.1%) and 75A (8.7%) in their order.
This study is to classify the shape of the body by means of the drop value of the middle-age women. Drop value is based on the circumstances of the body deciding the dimentions of the clothes. Therefore, the study based on the drop value seems to decided the measurement of the clothes in making mass production of ready made clothes. In order to put measure items on this study of the value on 'The fifth survey of body measure of Korean', select 785 people in middle-aged women aged from 40 to 59. And considering the characteristic of upper-drop and lower-drop, and swelling belly by accumulated fat, selected five items(Bust Circumstance - Waist Circumstance, Hip Circumstance - Waist Circumstance, Hip Circumstance - Bust Circumstance, Waist Circumstance(Omphalion) - Waist Circumstance, Hip Circumstance - Waist Circumstance(Omphalion)). The result of the study is summarized as follows. Type 1, M type of the body showed the distribution of 32.5% and belonged to low body development style. The line of human body is the nearest of the four bodies in middle-age woman out of whole shapes of 4 types and the line of human body is close to middle-age woman. Type 2, X type of the body showed the distribution of 40.8% and the line of human body remarkably showed. Type 3, H type of the body showed the distribution of 12.4% and the line of human body appears least. This group was larger than any other group in having more fat in the belly above the circumstance of the hip than other groups. Type 4, Y type of the body showed the distribution of 14.4%. This type was upper half of body development style, waist was slender, and there was seldom the bend around the circumstance of belly and hip.

The purpose of this study were to explain the difference in body dimensions and body shape between the early in the twenties and the late in the twenties and to get information clothing construction. Subject were 483 Korean males, which were extracted from men's physique investigation on June to August in 1989, consisted of 149 aged $19\~24$ and $25\~29$. T-test and factor analysis were applied to 52 measurement items and 58 indices. The Result of the study were as follow; 1. As regards $19\~24$ aged group, they were taller their waistband level was higher than the late in the twenties. Upper arm and thigh were thick in comparison with trunk. As the difference between shoulder and waist in dimension was great, they showed reverse triangular silhouette. As regard $25\~29$ aged group, their body from variation between individual was greater than that of 19~24 aged group and they were obese on mainly waist and abdominal parts. For that reason, waist band level became low and their shoulder and hip looked slim relatively that reason, waist band level became low and their shoulder and hip look slim relatively to bust and waist parts. 2. Between $19\~24$ aged and $25\~29$ aged groups, as each had charicteristic body from, there was the difference in factor structure. 3. The change of men's body from with age in their twenties was obeseness on the whole body but the increasing rate of upper arm and thigh girth was less than that of trunk girth.
