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.

In order to find out the relationship between the Eight Principle Pattern Identification of Yin-Yang, Exterior-Interior and the Sasang constitution, we analyzed the clinical data from 500 women with menstrual pain and women without menstrual pain. In the previous study, the subject's information of Typology Complexion Pulse and Symptom was collected, and Eight Principle Pattern Identification was executed based on this. Later, The relationship between the Sasang constitution and the Eight Principle Pattern Identification was statistically analyzed. The obvious difference between the experimental group and the control group in the patterns of Yin-Yang and Exterior-Interior is that patients who complain of menstrual pain do not maintain harmony with the yin-yang ratio, it can be said that the patterns of Yin-Yang and Exterior-Interior can be a identification standard that significantly obscures the condition of the disease. There was a significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Yin-Yang. There was no significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Exterior-Interior. It is assumed that the relationship between the Eight Principle Pattern Identification and the Sasang constitution has changed depending on the difference a view of emotional Qi and pathogenic Qi.

This study was carried out in order to find out the pattern of the root resorption following maxillary incisor retraction after maxillary 1st bicuspid extration in maxillary protrusion patients. For this study, thirty two patient who received orthodontic treatment were chosen. The results were as follows; 1. Of the total 192 teeth, 61 teeth(31.77%) showed no apical root loss, 64 teeth(33.33%) fell into the class "slight", 46 teeth(23.96%) fell into the class "moderate". Only 21 teeth(10.94%) were classified as "excessive". 2. No correlation was noted between the amount of apical root loss and the types of tooth movement of the maxillary central incisors. 3. The patients who were treated with standard brackets had more changes in tooth axis and less movement of root apexes, but the patients with straight brackets had less changes in tooth axis and more movement of root apexes. 4. Comparing the degree of root resorption between bracket types, patients who had used standard brackets showed more apical root loss than patients who had used straight brackets. 5. The most frequent degree of root resorption observed in standard bracket patients was second degree, followed by first degree and third degree. The most frequent degree of root resorption observed in straight bracket patients was zero degree, followed by first, second degree and third degree.

This paper concerns an efficient aperiodic static crab walking algorithm for quadruped walking machine in rough terrain. In this algorithm, the requirements for forward stability margin and backward stability margin could be given differently in order to consider the slope of terrain and disturbances resulting from moving velocity. To restrict the searing regions for motion variables, such as moving distances until a leg is lifted or is placed, the standard leg transferring sequence is decided to be that of wave gaits. standard support pattern is also proposed that enables the quadruped to continue forward motion using the standard leg transferring sequence without falling into deadlock.

Standard temperature and absolute humidity weather correlations of Seoul for dynamic energy simulation have been developed regressing the measured data compiled by the Korea Meteorological Adminstration during a 10-year period from 1991 to 2000. The mathematical equations can generate the daily and yearly variations of outdoor weather data with consistency unlike the measured data which may show abnormal behavior, Considering that each hour of the day follows a certain yearly pattern, the correlations are developed for each hour. The derived 24 simple mathematical equations can be used for estimating outdoor temperature and humidity conditions for any arbitrary time of the year.

The objectives of this study were to investigate whether heel height changes in the U.S. market occur in a cyclical pattern and heel heights show greater within-year variability over time. Heel height data from U.S. Vogue's spring and fall editions were analyzed over the time period 1950~2014. A total of 1581 pieces of data were measured in millimeter units using Adobe Illustrator and standardized by dividing the height of the heel by the shoe length through the curved sole line. To analyze the cycle pattern of heel heights, the yearly averages were standardized by using three-year moving average technique to average out the irregular components of time series data and give a better indication of the long-term fluctuation of heel height. To identify the degree of within-year variability of heel height, the standard deviation of the average measurements for a year was calculated, and then decade averages were drawn from the yearly averaged standard deviation. One-way ANOVA was conducted to compare the within-year variability of data in heel height over the time period studied by decade. The results showed: First, there was a trend toward higher heels from the early 1950s to 2011. Second, four cyclical movements of heel height were observed from 1950 to 2007, and heel heights gradually decreased after 2008. Third, the within-year variability significantly increased over time, especially after the 1980s.
