In case of lipsticks, observer's subjective sensitivity has been the main index to estimate gloss and gloss-lasting capability. The glossmeter has been applied to measure the gloss of make-up cosmetics like nail enamel, however is not effective for lipstick because of uneven sampling. Also gloss-lasting capability couldn't have been measured. In this study, we optimized measurement methods of gloss and gloss-lasting capability of lipsticks, which are highly correlated to subjective sensory tests. We set up the standard methods of gloss measurement by changing application conditions, for example, materials, sizes and application number of times and so on. And we introduced optimizing measurement system, in which shaking speed and temperature were controlled to measure gloss-lasting capability. Applying our methods, the gloss values were very close to the results of sensory tests, and we could express the gloss and gloss-lasting capability of lipsticks numerically Repeatability and reproducibility of our methods were certified by six-sigma statistical tool.

Objective : The purpose of this study was to examine the differences between motor functions and executive functions according to the timing of children with attention deficit hyperactivity disorder (ADHD). Methods : The subjects were 32 children with ADHD aged between 6 and 12 living Busan. To assess the timing, Long Form Assessment (LFA) of Interactive Metronome (IM) was used. Bruininks-Oseretsky of Motor Proficiency, Second Edition (BOT-2) were also used to assess motor functions. STROOP Color and Word Test and Children's Color Trails Test were used to evaluate executive functions. Mann-Whitney U tests were used to determine the differences between the executive functions and the motor functions according to the timing. Results : Comparing the inter-group motor functions according to the timing, there was a statistically significant difference in the Fine manual control and Fine motor precision in BOT-2 (p<.05). Comparing the inter-group executive functions according to the timing, there was not statistically significant difference (p>.05). Conclusion : Among the deficits in ADHD children, we could see the differences between motor function and executive function according to timing function. This study would be meaningful in that the results could be a basic data for study on the timing of children of ADHD in the future.

The purposes of this study were to examine whether aquatic exercise has influence on the neuroplasticity and vestibulo-motor function in diffuse brain injury rats. 80 Sprague-Dawley rats were assigned to four groups; Group I: control group (n=20), Group II: aquatic exercise (n=20), Group III: treadmill exercise with change of velocity and inclination (n=20), Group IV: simple treadmill exercise (n=20). And we applied exercise each groups for 3 weeks except Group I. Before the rats were sacrificed to identify immunohistochemistry study at each time of measurement day, Rota-Rod test was given to assess changes in vestibulomotor function. then, the immunohistochemistry study of GAP-43 in discrete regions of the rat brain was performed to measure changes in neuroplasticity. The results demonstrate that aquatic exercise group is more effective than other groups. expression of GAP-43 and vestibulo-motor function were increased most in aquatic exercise group. Therefore, this study suggest that aquatic exercise may effective therapeutic approach to increase neuroplasticity and vestibulo-motor function in traumatic brain injury.

This paper is the study on the safe design of joint controling the pressure and temperature by connecting between pipes laying with the flexible joint. This study aims at decreasing the excessive pressure applied in the pipe and preventing the accident occurrence in order to solve the pipe damage by extraction and contraction due to the pressure of open air and transport gas. The flow properties of each model are investigated through the simulation analysis by applying three kinds of the flexible joints. When transport gas passes the flexible joint, the flow characteristics of heat, pressure and velocity at pipe laying are analyzed. It is thought to be contributed to the safe design due to the shape of the flexible joint by using the result of this study. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

Purpose: This study examined the improved sensory, hand function, postural balance and activities of daily living (ADL) through somatosensory stimulation, such as the facilitation of functional reaching and tactile, proprioceptive stimulus of the upper limb (UL) and hand. Methods: Seventeen stroke patients having problems with motor and somatosensory deficits were selected in Bobath Memorial Hospital adult rehabilitation center. The patients were divided into two groups; the sensorimotor deficit group (SMDG) and motor deficit group (MDG). Somatosensory stimulation on the UL, physical therapy and occupational therapy were carried out three times a week over a six week these treatments were performed in both group period. To compare each group, the following assessment tools were used: such as tactile detection thresholds (TDT), two point discrimination on the affected side (TPDas), unaffected side (TPDus) stereognosis (ST) manual function test, hand function on the affected side (HFas) and unaffected side (HFus), Postural Assessment Scale for Stroke (PASS) and Korean version Modified Barthel Index (K-MBI). Results: In the SMDG, somatosensory stimulation on the UL was statistically important for TDT, TPDas, TPDus (except for the thener), ST, hand function on HFas, on HFus, PASS length of displacement with foam (LDFSEO), and K-MBI. In the MDG, somatosensory stimulation on the UL was important for TDT, TPDas, TPDus (except index finger) length of displacement with the eyes open, LDFSEO, HFas, HFus, PASS and K-MBI. In addition, there was a significant difference in the PASS between SMDG and MDG. Conclusion: Somatosensory stimulation on the UL affects the sensory, hand function, postural control and ADLs performance.

The study documents the analysis on characters and symbols shown in the pavement markings in the perspective of mathematics educators. The purpose of this study is to propose a pavement marking method that can enhance readability from the driver's eye position. To this end, this study analyzed the figure of the pavement markings that can be actually recognized by the projective geometry perspective. As a result, it proposed alternatives to the current pavement markings by introducing the concept of the compression ratio. Results of the study are as follows. First, the rule was established to obtain the compression ratio. If the observation of two viewing angles are x and y, then the compression ratio S is ${\sin}y/{\cos}\(\frac{x-y}{2}\)$. Second, we presented two alternatives to the pavement marking method for the displayed information. One is a method for improving the pavement markings in terms of the compression ratio, the other is a method by varying vertical length of the pavement markings while holding its width constant. Based on the outcomes from this study, a mathematical analysis can be further studied for the perception of speed according to the types of pavement marking line.

If a controlled sensory stimulation is given to the specific receptors, a reflex movement and motor engrams is achieved by the principle of neurophysiology. Based on this theoretical background, we choose 80 healthy person(male 40,female 40) and compare chronaxie of before stimulation with after stimulation. Also we measured chronaxie with same method. Stimulation was applied to the muscle belly by tapping. The results are summarized as follows; 1. The mean value of rheobase measured from the proximal part of upper extremity is 3. 56mA for male, 4.04mA for female. 2. The mean value of rheobase measured from the lower extremity is 4.19mA for male, 4. 37mA for female, which is higher than that of upper extremity for both male and female. 3. The mean value of chronaxie from the proximal part of upper extremity is 0.91msec for male, 0.87 msec for female, which means male is higher than female, and the average is 0.82msec. 4. The mean value of chronaxie from the proximal part of lower extremity is 1.04msec for male, 1.14msec for female, which means female is higher than male. 5. The decrease of rheobase after stimulation is prominent at the triceps brachii for male, biceps brachii for female. 6. The decrease of rheobase after stimulation is prominent at the tibialis anterior for both male and female. 7. The decrease of chronaxie after stimulation is prominent for both male and female at the triceps brachii from upper extremity and at the tibialis anterior from lower extremity for both male and female.
