The objective of this research is to observe the difference of the physiques and motor skills between groups when implementing indoors and outdoors the same physical activities based on the locomotor movement, nonlocomotor movement, manipulative movement suggested as physical activities in the health section of the national education program. The research subjects amount to a total of 290 persons, consisting of experimental group of 152 toddlers of 4 to 5 years and the comparative group that attend the private preschool “I” in “G” city. The experiment was implemented indoors and outdoors of the early childhood education institute once a week for 40 minutes, for 24 weeks. The preliminary test consisted of measuring the physiques (height, weight) and the motor skills (balance, coordination, flexibility, and agility). The post-test was the same as the preliminary test. In terms of the data processing method, the average of the post-level was adjusted after the average of the prior-level of the groups was made same because the preliminary levels between groups were not equal and applied the covariance analysis that verifies the difference of average of adjusted post-level. It has been implemented by SPSS 22.0 and the statistical significance level was set to 5%. To provide the experiment results, the experimental group that implemented physical activities outdoors showed statistically significant difference (p<.05) in physiques, balance, and coordination in comparison to the comparative group. But the comparative group that implemented physical activities indoors showed statistically significant difference (p<.05) in flexibility. There was no statistically significant difference between the groups in agility. The experiment result verifies that outdoor physical activities are more effective for developing young children’s physiques and motor skills. Due to the burden of childrearing expenses and parents working together for a living, most of the young children’s physical activities take place in indoors such as preschools, taekwondo centers, academies, and indoor playgrounds. But young children tend to lose interest in the artificially-constructed indoor environment and focus on smart devices. This early lifestyle connotes the possibility of increasing the amount of time one spends indoors through the adolescent to the adult life. Therefore, it is necessary to improve environments of the physical activity locations, recognize the importance of outdoor physical activities, and recommend outdoor physical activities for the development of young children’s physiques and motor skills through diverse types of physical activities.

The study selected 68 3-year-old infant men and 82 women who are volunteering at a daycare center in K-do I, Gyeonggi-do. The research was retrieved from October through November 2017 by delivering research questionnaires to infants and guardians. The contents of the questionnaire were made by parents and guardians to write items such as the time, place, time, method, and attitude of physical activities with their parents. The data were analyzed by using the statistical program of SPSS Windows version 22.0 to construct a cross tabulation by comparing the frequency and percentage of the combination frequency between the independent and dependent variables. First, parents believe that infants need physical activity, but parents lack participation in physical activities with infants. It was found that mothers spend more time with infants than their fathers. Second, parents were positively judging the attitude and appearance of infants participating in physical activities. Third, parents were allowed by the majority if infants asked for physical activity, and the main place was indoors (living room). It was also found that infants were allowed to play outdoors if they wanted to. However, the number of infants attending sports clubs outside of the country was small. Fourth, parents judged that it was possible for infants to receive the ball, kick the ball, dance, ride the tricycle, and stop the ball, but they judged that two-footed biking and jumping rope were impossible.

This study has the objective of analyzing the difference between age of children and fundamental motor skill achievement rate and finding out developmental tendency. Study targets were 393 children registered at child education organization located in city G and I in province K (149 at age of 3, 133 at age of 4 ad 111 at age of 5), and fundamental motor skills (movement exercise skill – stepping backward, running on one foot, running with raising knees, running while pushing, standing long jump, stable motion skill – standing on one foot, rotation, spinning like top, avoiding ball, rolling forward, manipulative movement skill – out-throwing ball, throwing ball precisely, bouncing ball, catching ball, kicking ball) achievement rates were measured. The results of this study are as follows. It showed that the children’s fundamental motor skill achievement rate had differences according to the age increase. When you present the age and fundamental motor skill achievement rate of children for each lower level zone, it showed the differences as follows: movement exercise skill achievement rates were 71.8% for age of 3, 85.3% for age of 4 and 95.7% for age of 5, stable motion skill achievement rates were 75.0% for age of 3, 86.4% for age of 4 and 94.1% for age of 5 and manipulative movement skill achievement rates were 33.6% for age of 3, 54.0% for age of 4 and 71.2% for age of 5. When you summarize these, fundamental motor skill achievement rate of children had differences according to the age, movement exercise skill achievement rate and stable motion skill achievement rate were found to be developed showing uniform rate achievement rate according to age increase, and manipulative movement skill achievement rate seems to have the tendency of gradually developing along the age increase slower than movement exercise skill and stable motion skill.

For driving, passenger has experienced various types of road situation; straight/curved roads, paved/unpaved roads. Long-time driving exposes passenger to centrifugal force and vertical vibration that cause driving fatigue. In this paper, a integrated seat control system including several air-bladders and sensor signals (steering angle, speed, acceleration) is investigated. The system control the pressure of seat side bolsters's bladders in the curved roads and the pressure of seat cushion's bladders according to road roughness. The purpose of the control system is to improve the ride comfort of seat.

Many engineers are trying to predict seat comfort, but these predictions are very difficult. The automobile seat is composed of the foam with the frame. Lumbar support is very important part in car seat, also. Using data from a seat material property, pam-comfort program finds the factor that we will make a major parameter of seat comfort. On the basis of result knowledge of the analysis, we can evaluate the seat comfort factor and find the best way to solve it. Simulation program will be used to predict major parameter to seat comfort.

New human body models have been developed with recent anthropometry have for riding comfort simulation. External geometry of the models was acquired from the 3 dimensional whole body laser scanning of recruited volunteers in a driving position. The selection criteria for volunteers with standard size and shape were derived from a statistical factor analysis of the SizeUSA database. As a practical application of the model in a design process, comfortable driving postures were constructed by using the Cascade Prediction Model (CPM) which takes into account both, interior package layout and the driver’s anthropometry.
