An experimental study was made to compare digital display with analogue-digital display during a digital pursuit tracking task under the preview information. The effect of preview on performance during the tracking task was analyzed for the different preview spans and the different characteristics of the information input. The data from ten subjects revealed that the RMS error performance was improved substantially in the case of one preview point than in that of no preview. It was obtained from the result of the experiments that the improvement ratio of analogue digital to digital display increased to 48%.

This paper presents a hybrid model solution for user motion recognition. The use of a single classifier in motion recognition models does not guarantee a high recognition rate. To enhance the motion recognition rate, a hybrid model consisting of decision trees and artificial neural networks is proposed. We define six user motions commonly performed in an indoor environment. To demonstrate the performance of the proposed model, we conduct a real field test with ten subjects (five males and five females). Experimental results show that the proposed model provides a more accurate recognition rate compared to that of other single classifiers.

The purpose of this study was to analyze the previous make-up studies. A number of publications and journals were reviewed and analyzed carefully. The results of review and analysis were as follows: There were many different subjects in make-up studies and They can be divided into ten types : cosmetics purchase behavior, change of make-up culture and comparison, make-up trend by era, cosmetics industry's standing of today and strategy, art trend in make-up, brand preference of cosmetics, make up attitude, recognition about imported cosmetics and purchase behavior, color preference of cosmetics, the relationship between self-concept and make-up. In general, the cosmetic purchase behavior studies are conducted most actively. According to result that analyze existent study, special duality of cosmetics purchase action appears very variously according to standard of classification of study target and study target. But, study target and method of study are not various, and purchase behavior study collected with make-un and clothes is yew lacking. Therefore, in this study, wished to discover problem of virtue study because analyzes studies about previous make-up and present forward study direction.

Effort of rice resistant starch (RS) content on glucose blood level of normal Subject was examined using Suwon 464 and Ilpum, haying different RS contents. Enzymatic-gravimetric method showed RS contents of Suwon 464 and Ilpum were 16.3 and 0.7%, respectively. Both rice varieties, each containing 50g carbohydrate, were pressure-cooked and fed to ten healthy male volunteers after overnight fast. Significant difference was observed in 60 min blood glucose levels of Suwon 464 and Ilpum after meal, showing $90.3{\pm}4.8$ and $111.6{\pm}2.7mg/dl$, respectively (p<0.01).

The present investigation examined hammering performance, physiological response, preceived exertion, and user preference with regard to hammering in vertical (wall) and horizontal (bench) orientations, and with regard to using two different hammers. Ten male subjects participated in the experiment. The results support previous findings that horizontally oriented hammering is faster than vertically oriented hammering. In addition, the results suggest that hammer differences can affect hammering performance and perceived exertion; although, the exact contributions of specific design characteristics could not be quantitatively determined. However, participants subjectively identified handle design, weight, and mass distribution as critical factors.

This research has been focussed on the evaluation of the driving speed in a graphic environment. Through the investigation of some electronic driving games, two factors related to perceived speed have been extracted. The two factors are distance and density of objects. Experiments have been executed for the two factors. The experiment is needed to acquire a relationship between speed perception and each factor. For experiments involving more than ten subjects, graphical representation of a vehicle and its surrounding environment has been obtained using three-dimensional tools, Pro/ENGINEER and dVISE. Based on the experimental results, relationships are formulated and plotted.

The biomechanical analysis of the load carrying effect on different floor surfaces has been conducted. Four different floor surfaces were prepared for ten subjects with each walking at a fixed velocity(1.33 m/sec) while carrying five different loads. The results showed that because of the significant interaction effect between floor slipperiness and the load carrying task, the load carrying effect should be analyzed according to different levels of the floor slipperiness, especially contaminant floors. On oily surfaces, slip distance(SD) and heel velocity (HV) increased whereas stride length(SL) decreased as load increased. In other words, significantly longer SD, faster HV, and no normal gait were found as load increased. As a result, a different protocol should be applied to measure floor slipperiness on oily floors as compared to dry surfaces for tribological approach.

This study investigated biomechanical response through the 3-dimensional virtual skeletal model developed and validated. Ten male subjects in standing posture were exposed to whole body vibrations and measured acceleration on anatomical of interest (head, $7^{th}$ cervical, $10^{th}$ thoracic, $4^{th}$ lumbar, knee joint and bottom of the vibrator). Three dimensional virtual skeletal model and vibration machine were created by using BRG LifeMOD and MSC.ADAMS. The results of forward dynamic analysis were compared with results of experiment. The results showed that the accuracy of developed model was $73.2{\pm}19.2%$ for all conditions.

Objective: The goal of this study is to calculate and compare the Maximum Lyapunov Exponent (MLE) for the anteroposterior, mediolateral and vertical displacement of the markers attached to bony land marks of the trunk and foot. Method: Ten young and healthy male subjects (age: 26.5±3.27 years, height: 167.44±5.12 cm, and weight 69.5±7.36) participated in the study. Three-dimensional positional coordinate of eight different trunk and foot marker during walking on tread mill were analysed. Results: MLE values for anteroposterior displacement of the marker were found to be significantly different with MLE values for mediolateral and vertical displacement whereas MLE values for mediolateral displacement of the marker shows no significant difference with the MLE values for vertical displacement of the markers at significance level 0.05. Conclusion: Finding of this study suggest that it is essential to consider the displacement in all three direction to examine the real characteristic of a gait signal.

Purpose: The purpose of this study was to identify the effects of low intensity blood flow restriction training (LBFR) on the central nervous system of healthy adults. Methods: Ten healthy right-handed adults (eight males and two females, mean age of 28.6 ± 2.87 years) were selected as study subjects. Functional magnetic resonance imaging (fMRI) was conducted to measure brain activation (BA) following LBFR and non-LBFR. The primary motor area, premotor area, and supplementary motor area, which are closely related to exercise, were set as the regions of interest. Results: The BA recorded during the LBFR condition was 931.7 ± 302.44 voxel, and the BA recorded during the non-LBFR condition was 1,510.9 ± 353.47 voxel. Conclusion: BA was lower during LBFR than during non-LBFR.
