The peak time, peak height, width at peak, and the width at 8 min of Mixograph increased as the amount of sodium chloride in yellow alkaline noodle sheet was increased. The peak time of the Mixograph duration increased almost twice when 0.5% sodium carbonate was added to yellow alkaline noodle sheet, but decreased when the amount of sodium carbonate was above 0.5%. The peak height decreased as the amount of sodium carbonate increased. Protein content and sedimentation values showed positive correlations with the Mixograph peak height, width at peak, and width at 8min. The pasting temperature, peak viscosity, minimum viscosity, and final viscosity increased as the amount of sodium chloride in yellow alkaline noodle sheets was increased for all wheat flours. The peak viscosity, minimum viscosity, and final viscosity also increased as the amount of sodium carbonate increased. The pasting temperature showed a positive correlation with the water retention capacity and the alkaline water retention capacity.

The author investigated the timing of land and wrist ossification events taking place in the hamate and pisiform by means of roentgenographic examination and its relation to the peak growth velocities in body height. Materials obtained included 493 sheets of X-ray films taken from 257 boys ana 236 girls aged between 7 and 17 years lived in Seoul area. The results indicate that; 1) The average ages at occurrence of initial ossification of the hook of the hamate were 12 years 3 months in boys and 10 years 1 month in girls. 2) The average ages at which advanced ossification of the hook of the hamate occurred were 13 years 7 months in boys and 11 years 11 months in girls. 3) Initial ossification of the pisiform appeared at 13 years 0 month in boys and 10 years 2 months in girls. 4) All three ossification events in hand and wrist, and peak growth velocity in body height occurred earlier in girls than in boys. 5) Initial ossification in the hook of the hamate and pisiform preceded or coincided with peak growth in body height in most boys and girls, on the other hand, advanced ossification in the hook of the hamate occurred around peak growth in body height but in girls did it after peak growth in body height. 6) It would appear that initial ossification in the hook of the hamate or in the pisiform, both for boys and girls, provides a better indication of approaching peak adolescent growth in body height. 7) Advanced ossification in the hook of the tamale would indicate that the period of cercumpuberal peak growth had teen entered or finished.

In this paper, we propose a stress analysis on foot by lifting task attitudes. Maximum force and peak pressure were measured on 8 body regions by Pedar system in order to analysis the stress which is affected by task style and angle on foot when Manual Materials Handling task. As for the peak pressure of the whole foot as to the task height during the lifting task, the height from Knuckle to Shoulder was the least in the peak pressure. Also, as for the maximum force and the peak pressure of the whole foot as to the task angle during the lifting task, it could be seen that the more an angle increases, the stress influencing on a foot jumps. As for the maximum force and the peak pressure by foot region as to the task height in case of the lifting task, the height from Knuckle to Shoulder is indicated the smallest value in the maximum force and the peak pressure, thus there is necessary to attain the work design that considered this. Also, as for the maximum force by foot region as to the task angle in case of the lifting task, 0° tasking is indicated to be least, thus there is necessity to be attained the tasking design in a bid to prevent the existence of an angle. The results of this paper are thought to be helpful to the suitable work design, to the prevention of musculoskeletal disorders related to the lower limbs, and to the design of ergonomic safety shoes.

This study's purpose is to clarify the growth pattern of Down Syndrome cases -particulary centering on the adolescent growth pattern - and to draw up a standard growth chart on body height and weight which is one estimation of physical growth for the effective caring of their health. I sampled 269 Down syndrome cases (Male 151, Female 118) whose ages ranged from 6 years of age to adulthood and 348 normal control cases (Male 175, Female 173) who were in same age group with Down Syndrome. We also picked 124 Down syndromes cases(Male 70, Female 54) and gathered 8 year longitudinal data on their body height and weight. The results were that, I found Down syndrome cases' height to be short and their weight to be overweight. As far as age at peak height velocity was concerned, boys were at 11-12 years of age and girls were at 10-11 years of age, showing that girls were about one year faster. Peak height velocity was 6.8cm/yr for boys and 5.4cm/yr for girls. The age at peak weight velocity were 12-13 years for age for boys and 10-11 years of age for girls. Peak weight velocity was 5.7kg/yr for boys and 4.3kg/yr for girls. The menarche age of girls with Down syndrome was anticipated to come about 2 years after peak height velocity and peak weight velocity. Finally, we drew up a standard growth chart and compared it with that of the NCHS, which caused us to come to the conclusion that the Standard Growth Chart for Down syndrome cases in Korea that came out of this study was appropriate for the growth-assesment of Down syndrome.

A considerable change observed in X-ray diffraction during the muscle contraction was that the movement of myosin head and conformational change of contractile monecules were occurred in the muscle contraction. Time slice requires tension peak after the onset of stimulation and the height of tension peak depends on the number of twitch cycle. The intensity of I$_{11}$, I$_{10}$, 143${\AA}$ reflection is measured with 5ms time resolution and is recorded in isometric tension. The peak height of I$_{11}$ and 143${\AA}$ intensity is changed after the onset of a stimulation I$_{i}$, and the length of twitch is shortened by successive twitches in the case of stimulation TI$_{i}$. On the other hand, the peak height of I$_{11}$ and 215${\AA}$ intensity starts to decrease at the 1st twitch and remains constant at low peak hight without appreciable recovery during the contraction term. In the case of uccessive twitch stimulation, the myosin heads of muscle are once moved from their resting position and never returned to their initial position.

This study tries to show the physical growth patterns and various adolescent characteristics by using longitudinal data for the height, weight, chest girth and sitting height of 1, 132 high school students in Seoul. And this study also tries to show what influencing factors on the physical growth of this aged population. The followings are the results. 1. The boys have their peak velocity of height when they are 12~13 years old. And the girls have when they are 10~11 years old. Peak velocity of weight for boys is at the age of 13~14. And for girls is at the age ofr11~12. Peak velocity of chest girth for boys is at the age of 12~13. And for girls is at the age of 11~12. Peak velocity of sitting height for boys is at the age of 13~14. And for girls is at the age of 11~13. So girls of this period grow more rapidly by around two years than boys. 2. The menarche of girls begins at the age of 12.4. So it begins 1.4 year before peak height velocity period. 3. Of life behavior boys contingency coefficient between essential time and height and weight is .5150 and .479 5, that between studying time and height and weight is .3344 and and .2912(In case of girls is .4735, .4321, .3247, .3134).

To investigate the relationship between the pubertal spurt in body height and bone maturity of the hand-and-wrist in normal occlusion, the author X-rayed the hand-and-wrists of 1,141 students (male 614, female 527) and assessed their bone maturity. In this study, eleven skeletal stages were selected. The bones used to determine skeletal maturity were the ulnar sesamoid of the metacarpophalangeal joint of the first finger, the epiphyses of the proximal, middle, distal phalanges of the third finger, and middle phalanx of the fifth finger, and distal epiphysis of the radius. From the longitudinal data for height, an assessment was made of the change in growth velocity. The pubertal growth stage was divided into onset and peak height velocity phases. The results were as follows; 1. The onset of the pubertal growth was between the $PP_3=\;and\;MP_3=$ stage for boys, and between the $MP_3=\;and\;MP_5=$ stage for girls; the mean age of onset was 10.6 years for boys and 9.0 years for girls. 2. The peak height velocity was between the S and $MP_{3_{cap}}$ stage for boys, and between the $MP_{3_{cap}}$ and $MP_{5_{cap}}$ stage for girls; the mom age of peak height velocity was 12.5 years for boys and 10.9 years for girls. 3. As the stages of bone maturity progressed from $DP_{3u},\;to\;PP_{3u},\;MP_{3u}$, Ru, the peak height velocity had been reached, and the growth rate retarded, therefore the approach to full physical maturity was attained. 4. The evidence for the period of onset, peak height velocity and bone maturation suggested that girls were in advance of boys. During the latter part of pubertal growth, the rate of boys' bone maturation was faster than that of girls'.

From simultaneous recordings of the external photoglottography, intra-oral air pressure (P_io), airflow and acoustic data from four native Seoul Korean speakers (2 male and 2 female), we have found that the two fricatives are not significantly different in glottal opening peak and airflow peak height either word-initially or word-medially and that the duration of aspiration is significantly reduced in word-medial /s/, compared to those in word-initial /s/, not in /s'/. We have also found that the duration of a high P_io plateau is significantly longer in /s/ than in /s'/ both word-initially and word-medially and that airflow resistance (R=P_io/U) at the onset and offset of a P_io plateau and at the time of airflow peak height is significantly higher in /s'/ than in /s/ across the contexts. However, the differences in P_io peak and F0 are not significant. In addition, the transition time to reach airflow peak height from the offset of a P_io plateau is found to be significantly longer in /s/ than /s'/ in both word-initial and word-medial positions. No significant differences in glottal opening peak and airflow peak height confirm that /s/ is specified as [-spread glottis] like /s'/. As for the other significant differences, we propose that /s/ is [-tense], and /s'/ [+tense].

This study was performed to determine whether a pulse analyzer was useful 1) to characterize the variables of pulse wave of cerebral infarction patieno (CI), compared with those of healthy subjects, as well as 2) to determine Sasang Constitution in CI and healthy subjects. 1. Calibrated in Gwan, the amount of energy(Energy), height of main peak(H1), height of aorticvalley(H2), height of aortic peak(H3), total area of pulse wave(At), and area of main peak width(Aw) of the CI group were higher than those of the healthy group. 2. Calibrated in Cheek, Energy, H1, H2, H3, height of valve valley(H4), At, Aw, and main peak angle(MPA) of the CI group were higher than those of the healthy group. 3. Among the healthy (subjects) group, Taeumin showed the highest contact pressure(CP) and height of valve peak(H5) calibrated in Chon. The main peak width divided by whole time of pulse wave(MPW/T) calibrated in Gwan and Cheok, was highest in Soyangin and was lowest in Taeumin. The H3 divided by H1(H3/H1) and the time to valve valley minus the time to main peak and divided by T[(T4-T1)/T] calibrated in Cheek were highest in Soyangin. The time to main peak(T1) was longest in Soumin. 4. Among the CI group, At calibrated in Chon was widest in Taeumin and was narrowest in Soumin The time to aortic peak(T3) calibrated in Cheek was longest in Soumin and was shortest in Soyangin. The time to valve peak(T5) was shortest in Soyangin. 5. There were main effects of cerebral infarction in the area of systolic period(As) and area of diastolic period(Ad) calibrated in Chon, Energy calibrated in Cwan, and Energy, H1, H2, H3, (H4+H5)/Hl, and MPA calibrated in Cheek. 6. There were main effects of Sasang Constitution in (T4-T1)/T, area of systolic period(As), and Ad calibrated in Chon. 7. The interactions between the cerebral infarction and Sasang Constitution were observed in H5/H1 , T, At, As, Ad, and MPA calibrated in Chon, H4, T4, (T4-T1)/T, As, and Ad calibrated in Cwan, and 74,75, and MPW calibrated in Cheok. Therefore, we concluded that pulse analyzer was useful to determine the risk degree of cerebral infarction and Sasang Constitution.
