This study was performed to establish the Cephalometric standards and growths change of Korean Teen aged group by McNamara's Analysis. The data from Cephalometric films of 161 male and 205 female subject aged from 10 to 18 years of Normal Korean were used for this study. The following results were obtained: 1. Means, standard deviation from measured values in each age group and sexual values were obtained. 2. Greater measurement stowed in male than female in Condylion to point A, Condylion to Gnathion, MaxilloMandible differential and ANS to mouton in linear measurement of 18 age group. 3. Condylion to point A, Condylion to gnathion, MaxilloMandible differential and ANS to Menton are increased as the age increased. 4. Facial axis angle and Mandible plane angle of 15 and 18 aged group showed less value than that of 10,11,12 age group. 5. There was no significant value changes of Lower incisor to A-Po, SNA angle and Lower pharynx by the increasing of age.

The changes in the corpus callosum (CC) with age and gender remain largely subject to dispute, which might come from the different strategies for analyzing the size and shape of CC. We have investigated this issue by measuring some variables reflecting the spatial orientation of CC on magnetic resonance imaging in Koreans, which minimize individual variances in the brain. The subjects were composed of young adults in their twenties (51 male, 59 female) and elderly adults in their sixties and seventies (60 male, 71 female). The total area of CC, length and height of CC, the central angle and the four angles suggested by Oka et al. were measured. The whole area and the central angle of CC were not significantly affected by age and gender. The height and length of CC were significantly greater in elderly people. The angle connecting genu, upper notch of pons and splenium was significantly larger in the elderly group. Furthermore, all four angles were significantly different between male and female subjects. These results confirm that the spatial orientation of CC is influenced by age and gender.

The purpose of this study were to analysis on quality properties of lower extremity of patient with stroke by the existence of the independent walking. We recruited fourteen adults after stroke(7 male, 7 female; mean age, 64y) for our study. The subjects were divided into two groups; independent walking group(3 male, 3 female) and non-independent walking group(4 male, 4 female). We used in this study included a B-mode ultrasonography scanner with a 7.5 MHz linea probe. During the experiment, the subject was seated in the chair. The echogenicity(density, white area index; WAI) of the tibialis anterior and rectus femoris muscles were measured on both sides of the leg. In both of the density and WAI, the tibialis anterior muscle were significant differences between paratic side and non-paratic side, the independent walking and non-independent walking group. However, in both of the density and WAI of the rectus femoris muscle were only significant differences between paratic side and non-paratic side. This study showed that stroke and the independent walking have influenced on quality properties of lower leg. Especially, the independent walking has influenced on the tibialis anterior muscle.

This study analyzes the characteristics of good impression using speech manipulation scripts and investigates the characteristics of preferred speech voice. Fourty male and female college students participated in this study. They have been exposed to the Gyeongsang dialect spoken by their friends and family for more than 15 years. Two sample voices(1 male and 1 female), considered as giving good impression, were subject to voice analysis. Two students were asked to read the sample paragraph of 'Walking' and their voice samples were analyzed through Praat. The collected speech data were manipulated into 4 different sets by changing pitch level, degree of loudness and speech rate. First, both men and women received good impression more from pitch-lowered sound than from the original one. Second, men tended to receive good impression more from slightly louder voice than from the natural-pitched one. Third, it was shown that men often felt more drowned to a voice at slightly faster speech rate than at the original speech rate. Overall, both male and female listeners favored lower pitch over the original pitch. Men tended to prefer louder voice sound while women preferred less loud one. Men received better impression at a lower speech rate but women at a faster speech rate.

Purpose : The purpose of this study was to analysis on diaphragm thickness and lung function of stroke patients by walking ability. Methods : We recruited thirty-five adults after stroke(20 male, 15 female) for our study. The subjects were divided into two groups; independent walking group(11 male, 9 female) and non-independent walking group(9 male, 6 female). Assessment of diaphragm thickness was performed using ultrasound in B-mode with a 7.5 MHz linea probe. During the experiment, the subject was seated in the chair. All subjects performed maximal expiratory flow maneuvers using a spirometer in order to determine the forced expiratory volume in 1 second ($FEV_1$), forced vital capacity(FVC), peak expiratory flow(PEF) and $FEV_1$/FVC. Chest expansion was measured with a tape-measure placed circumferentially around the chest wall at the xiphoid process. The collected data analyzed by independent t-test. Results : The diaphragm thickness were significant differences between the independent walking and nonindependent walking group. Values of forced vital capacity, forced expiratory volume at one second, peak expiratory flow in pulmonary function tests were significant differences between the independent walking and non-independent walking group. However, chest expansion were not significant differences in both of the group. Conclusion : This study showed that walking ability of stroke patients have influenced on diaphragm thickness and pulmonary function.

The purpose of the study was to investigate the influence of salt (NaCl) recognition threshold and pleasant salt concentrations of Korean rural elderly subjects on preference of salty food as well as food group consumption patterns. The subjects were 213 elderly people (male 71 and female 142) over 65 and under 90 yr of age from Sunchang area. The higher values were found with male subjects in the areas of basic taste recognition threshold and pleasant concentration level of salt. The taste sensitivity scores of male subjects did not decrease with the increasing age, but female subjects exhibited a significant decrease with the age. The major determinant factor of salt preference of the elderly subjects in this study appeared to be personal pleasant concentration of salt rather than salt recognition threshold level and this trend was more evident in males than in females. The subject group of lower salt pleasant concentration i.e. consuming less salt showed the higher number of fruit and fruit juice intakes per week, and higher MNA (define this) scores were implying that they display more desirable nutritional status. Therefore, nutritional education focused on not only a variety of food consumption but also lowering pleasant salt concentration levels is advised to improve the quality of nutrition in the elderly.

This study examined the effect of vocal loudness on nasalance measures, under the conditions of three sentence patterns (i.e., Oral sentences, Mixed sentences, Nasal sentences). The vocal loudness level was classified into soft voice (55 dB), medium voice (65 dB) and loud voice (75 dB). The participants in the present study were 30 normal adults (male: female =1:1). Kay's Nasometer 6200 was used to measure nasalance and Sound level meter was used to adjust the loudness level. The results of the present study are as follows. Firstly, the change in vocal loudness is in the following. In the Oral sentence stimuli, the loud voice for both male and female showed the highest nasalance degree, and the medium voice the lowest level. In the Mixed and Nasal sentence stimuli, however, male participants showed the highest degree of nasalance in the soft voice, and the lowest degree in the loud voice, and female showed the highest degree of nasalance in the soft voice and the lowest in the medium voice. Secondly, when each subject's nasalance scores were ranked in a ordered manner, noticeable tendency. Lowest nasalance score occurred in the loud voice and the highest nasalance score was recorded in the soft voice during participants' reading of the Nasal sentences. However, it was hard to find such pattern in the Oral sentences. It is assumed that velopharyngeal function could be related to these findings. Furthermore, the findings associated with vocal loudness may have diagnostic as well as clinical implications.

The purpose of this research was to investigate the effects of clothing style and color of male casual wear on image perceptions and age evaluations. $4{\times}2$ (top color${\times}$trouser color) and $2{\times}3{\times}2$ (clothing style${\times}$clothing hue${\times}$clothing chroma) factorial designs were used as the experiment designs. Photoshop program was used to manipulate the clothing colors after creating photos of models wearing experiment clothing for stimulus. Subjects were 280 female college students from Seoul region and each subject responded to two stimuli. Factor analysis showed four factors of images of male casual wear; sociability, conspicuousness, softness and masculinity. Polo shirts were evaluated higher in sociability and softness than jumpers and nary blue trousers were evaluated higher in masculinity than beige trousers. High chroma clothing was assessed higher in sociability and conspicuousness than low chroma clothing. High chroma red jumpers displayed very sociable feel and low chroma blue jumpers displayed the lowest sociability. High chroma male clothing resulted in younger age perception but age was evaluated young when a black shirt was worn under the jacket when wearing a low chroma jacket.

Purpose: We attempt to assess the differences in the degree of lumbar lordosis in patients with lower back pain caused by the herniation of the nucleus pulposus and in normal people (divided into male and female groups). Methods: This study was conducted with 14 patients (7 males, 7 females) diagnosed with, and being treated for, lumbar herniated nucleus pulposus and 14 normal people (7 males, 7 females). In order to examine the degree of lumbar lordosis in these subjects, hip flexor lengthening tests were conducted and the lumbar curves were measured in three postures (supine, sitting, and prone) and the results were compared. Results: The measured values of the curves for the standing and prone postures showed statistically significant differences between the normal group and the patient group, between the normal male group and the male patient group, and between the normal female group and the female patient group (p<0.05). Conclusion: The measurement method that uses flexible curve rulers in the standing or prone postures can be usefully utilized in assessing the lumbar lordosis of patients with lumbar herniation of the nucleus pulposus.
