This study was made on the facial profile of the normal Korean children using the roentgenographic cephalograms. The subjects consisted 51 males and 47 females children of primary dentition with the normal occlusion and acceptable profile. For this study 13 soft tissue profile landmarks were plotted and 14 liner length, 9 soft tissue thickness, 8 vertical height length, 12 angles of soft tissue profile, and 2 vertical proportion were measured. The mean and standard deviations in the subjects were calculated and compared between male and female. The following results were obtained : 1. By the significant test, total facial convexity angle and soft tissue thickness were no significant difference between both sexes. 2. Lower facial height was greater than upper facial height in both sexes. 3. The vertical length of the upper and lower lips were 21.95 mm, 40.74 mm in male and 21.62 mm, 39.63 mm in female. 4. In the relationship of the upper lip and lower lip to the Ricketts' esthetic line, the male was 1.3 mm, 1.18 mm and the female was 1.16 mm, 1.27 mm front of the esthetic line. 5. Compared with the angulation of flush terminal plane group and mesial step group, the mesial step group was greater than the flush terminal plane group except the chin angle.

On the contrary to the increasing needs of shape qualities, most of quality inspections are carried out by manual or operator's insight. To find the causes of shape inferiority, it is required to gather and analyze the shape measurement data. As a result the winding profile measurement system ($TELE-SCANNER^{(R)}$) is developed to analyze the coiling process and automate the manual measuring process for winding profile of hot-rolled coils. The winding profile measurement system measures and analyzes winding profile shapes of hot-rolled coils, and classifies them into several dominant patterns that are related to normal or abnormal mechanical conditions of down-coiler. The system also contains analysis software to quantify the winding profile shapes and patterns, and to produce statistics to help search the causes of profile shape inferiority.

Purpose: The purpose of this study was to identify the Health Promotion Life Profile of normal-weight and obese children, and factors related to obesity in elementary school children, and provide basic data for the development an obesity management program for these children. Method: The survey participants were 878 fourth to sixth grade elementary school children in Gwangju. $x^2$-test, t-test, ANOVA and multiple logistic regression with the SPSS program were used to analyze the collected data. Results: The Health Promotion Life Profile showed significant differences between normal-weight and obese groups according to food habits (t=3.305, p= .001) and exercise habits (t=-4.065, p=< .001). The Health Promotion Life Profile of obese children was also significantly different according to interest in weight control (F=3.044, p= .050), regular breakfast (F=3.699, p= .014), regular meals (F=6.868, p= .002). The multiple logistic regression analysis, showed that factors in obesity were significantly different according to gender, interest in weight control, fast eating, overeating and predilection for some food. Conclusion: The results of this study suggest that items on Health Promotion Life Profile such as food habits and exercise habits should be included in education programs to prevent obesity in elementary school children.

A general program of three dimensional profile design of impellers for centrifugal/fixed-flow compressors is successfully commercialized using Bezier curves and quasi-3D flow analysis methods. Control points for meridional hub and shroud contours and blade camberline angles are arbitrarily changed to give smooth Bezier curves. With specified blade normal thicknesses, contructed geometry is instantly analyzed using flow analysis methods to be checked.

In this study, the sliding wear in spur gears, using Archard's wear model, is analyzed. Formulas of tooth sliding wear depth along the line of action are derived. The tooth profile is modified Id make a smooth transmission of the normal loads and the cylinder profile for reducing the pressure spike is suggested. The sliding wear rate is calculated with these profiling results. We expect these modification methods to contribute to the reduction of sliding wear not only in the root, but the tip of tooth and tooth edge.

The purpose of this study was to survey a preference to the esthetic profile between Korean women and Korean American women. The interviewee were consisted of 30 Korean women and 30 Korean American women respectively. The survey has been done by using questionnaire. Altered facial profile of each normal male and female was got by moving maxilla, mandible to the front and back to survey the preference among the various profile. Then results were analyzed by SPSS program. The results were as follows, 1. In Korean women, in choosing the men's profile, 9 people out of 30, picked the standard profile as a most preferred profile, and bimaxillary retrusion and bimaxillary protrusion profile were followed by 6 people and 5people respectively. 2. In Korean American women, in choosing the men's profile, the 18 people out of 30, pick the bimaxillary retruded profile as a most preferred profile, and the standard profile were followed. 3. In Korean women, in choosing the women's profile, 18 people out of 30, picked the bimaxillary retruded profile as a most beautiful profile, and standard profile were followed by having 10people's voting. 4. In Korean American women, in choosing the women's profile, the 14 people out of 30, chose the bimaxillary retruded profile as a best one and the standard profile were followed by 12 people's voting. The preference of men's profile was significantly different between two groups (p<0.05) but the both group picked the bimaxillary retruded profile as a most beautiful when they choose the women's profile and then there was no statistical difference between the groups.

When we use the circular pipes for wastewater and storm water, we should be known the characteristics of the flow for accurate design. To elevate the design accuracy, we want to know the profile of flow. The roughness coefficient in the Manning equation is constant, but in actuality changed with the relative depth in circular pipe. This study was conducted to calculate the relative normal depth in changing the roughness coefficient (named relative roughness coefficient) with the relative depth in the analysis of gradually varied flow in the circular pipe by Newton-Raphson method. We performed the analysis of gradually varied flow using the relative normal depth and the relative roughness coefficient. We presented the 12 flow profiles with the relative depth and the relative roughness coefficient in circular pipe. The flow classification considering relative depth in circular pipe is available to analyse gradually varied flow profiles.

Purpose: The purpose of this study is to make clear the difference of the mental state between formal menstruation group and menorragia group. Methods: The patients suffering from uterine myoma or adenomyosis answered about menstruation and did a blood test and MMPI. They were analyzed by Mann-Whitney U-test. Results: The D scale of complain of a menorrhagia group is higher than normal menstruation group. (p<0.05) According to blood test, The F scale of anemia group is higher than normal group.(p<0.05) The D scale of menorrhagia with anemia group is higher than normal menstruation without anemia group. (p<0.05) The MMPI score of complain of a menorrhagia group, anemia group, and menorrhagia with anemia group showed 1-2 profile type. The MMPI score of normal menstruation group, normal result of the blood test group, and menorrhagia with anemia group showed 1-3 profile type. Conclusion: regardless of the rxistence of anemia, the group with menorrhagia tends to show a state of depression than the control group.

The deformation under radial pressure of rectangular dies for metal powder compaction has been investigated by FEM. The explored variables have been: aspect ratio of die profile, ratio between diagonal of the profile and die height, insert and ring thickness, radius at die corners, interference, different insert materials, i. e. conventional HSS, HSS from powders, cemented carbide (10% Co). The analyses have ascertained the unwanted appearance of tensile normal stress on brittle materials, also "at rest", and even some dramatic changes of stress patterns as the die height increases with respect to the rectangular profile dimensions. Different materials behave differently, mainly due to difference of thermal expansion coefficients. Profile changes occur when the dies are heated up to the temperature required for warm compaction. The deformation patterns depend on compaction temperature and thermal expansion coefficients.
