The purpose of this study is to identify with visual data whether interest in eSports affects the poster's information search. Scan path and hit map were collected using eye tracker and eye tracking program. As a result, 1) In the case of interest, the event was the first to notice, and in the case of non-interested was the first to see the title. 2) The amount of information collected by interested persons was greater. 3) In the case of interest, the most attention stayed on the event, and in the case of non-interested, the most attention stayed on the title. If additional research on eSports is conducted, various approaches can be used as marketing materials that can be applied to poster design production.

This study was carried out to evaluate the application possibility of UF Membrane System to papermaking industry in order to optimize the recycling of white water. In this study, for the efficiency test of UF modules, the MWCO(molecular weight cut-off) of the membrane was estimated by the COD measurement from UF filtrate water. From the rejection rate of membrane, three kinds of UF module were selected and evaluated in the factors of COD, SS, turbidity and flow rate.

This study is purposed to analyse the effects of long-term & one-time 10km running exercise from bone metabolic marker change on bone metabolism. 7 male members(18.6±1.08) from a marathon club were subjected to the study. They were allowed to do long-term 10 km running training once a week for 6 months. And bone metabolism mark was determined according to the respective times : before/after 6 months training, before/after 10 km race, one day after the race, 3 days after the race. The examination items of bone metabolism mark were serum calcium, phosphorus, paratyroid hormone, osteocalcin, calcitonin, alkaline phosphatase in blood and calcium, phosphorus, deoxypyridinolin in urine. The results of study were as follows; 1) There was no change in deoxypyridinolin and alkaline phosphatase but there was significant change in calcitonin, paratyroid hormone and osteocalcin(p<.01). 2) There was no change of Calcium in serum and urine but there was significant change of phosphorus in blood(p<.01). To make a conclusion, it is determined that long-term 10 km running at low intensity and low frequency tends to restrict bone metabolism circulation, but exercise at a little high level activates bone metabolism into building up bones and absorbing bones and finally shows up high bone metabolism circulation, which is inferred to have an effective influence on bone health. It is considered there is a possibility that different exercise intensity, even same kind of exercise, influences on bone metabolism sdifferently.

The purpose of this study was to evaluate the effects of mobilization of the sciatic nerve on hamstring flexibility, lower limb strength, and gait performance in patients with chronic stroke. This study was a randomized clinical trial with a crossover design. Sixteen subjects were recruited for this study. The subjects were randomly divided into two intervention groups and underwent either of the following two interventions: sciatic nerve mobilization or static stretching of the hamstring. We assessed hamstring flexibility, lower limb strength, and gait performance using a digital inclinometer, a hand-held dynamometer, and the 10-meter walk test, respectively. Subjects had a 24-hour rest period between each session in order to minimize carryover effects. Measurements for each test were assessed prior to and immediately after the intervention sessions. Using a two-way analysis of variance test with repeated measures, data from the two trials were analyzed by comparing the differences between both techniques. The level of statistical significance was set at .05. Sciatic nerve mobilization resulted in significantly better knee extensor strength (p=.023, from 15.32±5.98 to 18.16±6.95 ㎏) and knee flexor strength (p=.011, from 7.80±4.80 to 8.15±4.24 ㎏) in the experimental group than in the control group. However, no significant effects of static stretching of the hamstring were observed on hamstring flexibility from the ankle plantar flexion (p=.966) and ankle neutral positions (p=.210) and on gait performance (p=.396). This study indicated that the sciatic nerve mobilization technique may be more effective in muscle activation of the knee extensor muscle and knee flexor muscle than hamstring static stretching technique in patients with chronic stroke.

Meningioma is relatively common, benign, and extra-axial tumor accounting for about 20% of primary brain and spinal cord tumors. The World Health Organization (WHO) classified these tumors into Grade I (benign), Grade II (atypical), and Grade III (anaplastic) meningioma. Grade I meningioma which is slowly growing tumor and have some rare subtypes. Among them, metaplastic subtype is defined as a tumor containing focal or widespread mesenchymal components including osseous, cartilaginous, lipomatous, myxoid or xanthomatous tissue, singly or in combinations. We report a rare metaplastic meningioma overspreading nearly whole cerebral convexity from main extra-axial tumor bulk in the parietal lobe.
