The purpose of this study was to make suitabl skirts pattern for pregnant woman on the basis of their physical characteristics. 9 women who were 3,5,8 and 10 months pregnant were measured using Martin's anthropometric instrument on 12 items and sliding gauge on 4 items. The measures were analyzed statistically. Skirts pattern was developed based on the measurements of the essential items for skirts construction. The sensory evaluation was applied to estimate fittness and comfort in Rim's method skirt pattern. The items which showed a remarkable and significant increase were anterior waist circumference, anterior waist height and abdominal circumference. The anterior part of waist and abdorminal sections projected forward gradually. According to statistical analysis on the questionnaire, all the items showed significant difference between the new and the Rim's method skirts pattern with the new pattern having higher scores.

The purpose of this study is to develop a slim-fit jeans pattern that is suitable for the lower body of upper grade elementary school girls, who are beginning to show gender differences in body shape. Four age groups of two years each were considered for girls 7 to 14 years old. The mean and standard deviation of body measurements were calculated for each age group to analyze body shape variation, and hence the body characteristics of upper grade elementary school girls were identified. The high-frequency measurements of stature-waist circumference and waist circumference-hip circumference combinations were analyzed. In order to determine the size of each part of the jeans pattern and derive the drafting formula, the pattern sizes of brand A jeans, which had received a high score in the evaluation for ready-to-wear jeans(Kim & Lee, 2020), were used as the base criteria. In addition, the body sizes observed and calculated in the study were applied. Additionally, the requirements for better fit of ready-to-wear jeans, found in the survey on jeans wearing conditions and size dissatisfaction(Kim & Lee, 2019), were taken into consideration. Based on this research, a model set of jeans was prepared with the pattern developed and its fit evaluation was conducted. Thus, a slim-fit jeans pattern suitable for the lower body of upper grade elementary school girls was finalized. The pattern proposed in this study has excellent appearance and motion functionality, and is expected to contribute to reduce the fit dissatisfaction.

Objective: The purpose of this study was to investigate the relationship between the facial skeletal patterns and the shape of the mandibular symphysis in adults with malocclusion by using a structural equation model (SEM). Methods: Ninety adults who had malocclusion and had records of facial skeletal measurements performed using cone-beam computed tomography were selected for this study. The skeletal measurements were classified into three groups (vertical, anteroposterior, and transverse). Cross-sectional images of the mandibular symphysis were analyzed using generalized Procrustes and principal component (PC) analyses. A SEM was constructed after the factors were extracted via factor analysis. Results: Two factors were extracted from the transverse, vertical, and anteroposterior skeletal measurements. Latent variables were extracted for each factor. PC1, PC2, and PC3 were selected to analyze the variations of the mandibular symphyseal shape. The SEM was constructed using the skeletal variables, PCs, and latent variables. The SEM showed that the vertical latent variable exerted the most influence on the mandibular symphyseal shape. Conclusions: The relationship between the skeletal pattern and the mandibular symphysis was analyzed using a SEM, which showed that the vertical facial skeletal pattern had the highest effect on the shape of the mandibular symphysis.

A speech recognition system for separately pronounced Korean digits is described. The system is composed of four stages ; parameter extraction, segmentation by voiced-unovied analysis, formant tracking and pattern matching. Digit speech is segmented into an unvoiced segment and/or a voiced one using ZCR and energy measurements, then to estimate the first three formant frequencies a relatively simple formant tracking scheme is applied to the raw formant data extracted from linear prediction spectra. Finally, pattern matching is made using dynamic programmig method. Recognition experiment is carried out for 150 digit utterences spoken by three male speakers, and recgnition rate 94 % is obtained.

In this research, I classified adult women's back types through anthropometric measurement and photographic measurement to present a judging individual body size according to the type. Also, Ⅰ calculated regression fomula by types and presented the basic bodice pattern. The results were as follows: 1. The result of factor analysis indicated that 5 factors were extracted and those factors comprised 75.89% of total variance. 2. According to the cluster analysis, Ⅰclassified the back types into 6 types. Type 1 was passive posture in the upper and the lower parts of the back. Type 2 was active posture in the upper and the lower parts of the back. Type 3 had the lowest protrusion of the back. Type 4 had the upper part of the back which is mostly bent downward. Type 5 was the most suitable shape. Type 6 had the lower part of the back which was turned over the most. 3. Ⅰconducted a discriminant analysis to judge the body types of individuals. 4. For the calculation of measurements necessary for the basic bodice pattern, Ⅰpresented regression formulas by each type. 5. By conducting the wearing experiments, Ⅰsuccessfully made the final basic bodice patterns by types. As a result of comparative experiments between the basic bodice patterns and comparison bodice pattern, the suitability of basic bodice patterns were more highly assessed.

In this study, we develop a Korotkoff sound based automatic blood pressure measurement device including sensor, hardware, and analysis algorithm. PVDF-based sensor pattern was developed to function as a vibration sensor to detect of Korotkoff sounds, and the film's output was connected to an impedance-matching circuit. An algorithm for determining starting and ending points of the Korotkoff sounds was established, and clinical data from subjects were acquired and analyzed to find the relationship between the values obtained by the auscultatory method and from the developed device. The results from 86 out of 90 systolic measurements and 84 out of 90 diastolic measurements indicate that the developed device pass the validation criteria of the international protocol. Correlation coefficients for the values obtained by the auscultatory method and from the developed device were 0.982 and 0.980 for systolic and diastolic blood pressure, respectively. Blood pressure measurements based on Korotkoff sound signals obtained by using the developed PVDF film-based sensor module are accurate and highly correlated with measurements obtained by the traditional auscultatory method.

In this research, the fit of basic dresses was examined, by analyzing and comparing the satisfaction of fitness of basic dresses made by the draping method on a custom-made replica body form and that of a basic dress made by the flat pattern method. Basis dresses were produced by the draping method for each 52 subjects using custom-made body forms, and another kind basic dresses for each subjects were produced by the flat pattern method using measurements of body sizes. Both basic dresses received high scores for the satisfaction of fit, but the basic dresses produced by draping method received higher scores. Thus it is expected to produce a more successful fit by draping a basic dress on a custom-made body form. Future research using more subjects might confirm these results. A more concrete analysis through using additional satisfaction tests could be conducted. For example, each subject might also serve as an evaluator to rate her satisfaction of fit wearing each of the two custom-made dresses. Finally, examining various body forms is suggested.

The purpose of this study is to develop the pattern of safety clothes used at flat or mountainous areas and to identify the pattern of safety clothes by conducting experimental evaluation of virtual wear. Three subjects were selected, based on fire fighters' physical constitution. A prototype design for safety clothing was determined after in-depth interviewing of professionals and surveying of Forest service staff and related agency. Wearing test should be carried out in the order of pattern making, virtual and real wearing evaluation. For data analysis, technical statistical values should be obtained by using body measurements of subject, frequency analysis and T-test. The jacket is designed to have a front extension and the entire length of clothing enough for wearer to put on it over ordinary shirts or sweater. The collar of jacket is of round type. Cyber reality enables to identify the movement and activity of virtual fitting model and to find out errors or problems in safety clothing prior to on-the-spot wear test, thus raising the precision level of pattern. There was significant difference between real and virtual fit preference. The results show that the virtual try-on system need the development of a specific style.

The acoustic field analysis method is the superior calibration method for rectifying the ultrasonic probe sensitivity. This method also can be applied to evaluate the probe performance in clinical fields without numerical analysis and precise measurements. In this paper, we propose the method of acoustic field pattern analysis with probe channel division for the evaluation of diagnostic ultrasound probe characterization. In order to verify our purpose, we performed a set of experiments. We measured the acoustic-field pattern of the three inferiority probes by channel division to evaluate an acoustic field distribution and impulse response characteristics. By comparing the results of acoustic field measurement method with that of conventional method such as impulse response and live image test for linear array probes, it is demonstrated that the ultrasound field measurement method is more effective then conventional method in detection of defective elements.

The purpose of this study is to investigate the torso patterns by analyzing sensory evaluations. The anthropometric measurements for female college students were obtained between March and October in 1998, and a total of 197 anthropomatric data was used for the somatotype analysis. The appearance and fit of three kinds of torso patterns(ESMOD, FIT, and Muller & sohn) were evaluated by expert panel and the subjects. The results of the anthropometric measurements and sensory evaluations are as follows; The mean height of the anthropometric data for 197 students is 158.98cm. The largest proportion of the three somatotypes(H, M and A type) is big hip type(A type) consisting of 47.7% of all the respondents. The result of the torso pattern evaluations by expert panel indicates that the ESMOD pattern obtains the highest rating in general acceptability. A significant difference(p<.05) in the responses to two questions, the placement of the waist dart, and the gapping & creasing at back hip area was found. The ESMOD and Muller & sohn patterns are given the highest rating in the general acceptability. The result of the evaluation was obtained by the subjects. (Korean J. Human Ecology 1(2):100∼112, 1998)
