The diagnosis of canine diabetes mellitus is generally made by measuring serum fructosamine levels. The Rosental's end points Tas and El Din's kinetic, and Johnson and colleagues'kinetic techiniques were compared for the measuring serum fructosamine levels. In the Rosental's end point methods within-run and between-run coefficient of variability (CV) were 2.4-3.5% and 6.8-8.5%, respectively, and in the Tas and El Din's kinetic method, within-run and between-run CV were 1.3-3.0% and 3.4-3.9%, respectively. In the Johnson and colleagues'kinetic methods within-run and between-run CV were 0-1.8% and 3.1-6.8%1 ruts- pectively. Hyperlipidemia induced by oral administration of 3 ml of corn oil per kilogram body weight did not affect serum fructosamine concentration significantly in the Johnson and colleagues' kinetic method Johnson and colleagues'kinetic method is most reliable and consistant on the basis of comparison study.

Existing pedagogical issues of digital design including BIM have been focused not on potential of Digital Design but on skills of BIM or digital modeling tool. Kinetic facade can move or change material state to react surrounding environment conditions. It is a suitable design object for teaching principle of Performance Oriented Digital Design. Variables of movements affect multi-criteria of performances of kinetic facade, so different design approach from fixed facade design should be explored. Kinetic facade design process is proposed to study pedagogical issues of Performance Oriented Digital Design in this paper. Through Kinetic facade design process, students can understand conditions, variables, and performances of digital design.

Purpose : This study was intended to compare muscle activity in relation to knee joint angles on closed kinetic chain. Methods : A total of 13 subjects consisting of 5 adult males and 8 adult females were made to make movements maintaining knee joint angles at $30^{\circ}$, $45^{\circ}$ and $90^{\circ}$ on closed kinetic chain and the muscle activity occurring in their vastus medialis, rectus femoris and vastus lateralis was measured. Statistical data were analyzed using oneway ANOVA. Results : On closed kinetic chain, the muscle activity of the vastus medialis, rectus femoris and vastus lateralis increased the most at $90^{\circ}$ among the knee joint angles with statistically significant differences(p<0.05). Conclusion : On closed kinetic chain, it could be seen that as the angle of the knee joint increased, the muscle activity increased.

Purpose The purpose of this study was to compare the effects of closed kinetic chain exercise and open kinetic chain exercise in improving the balance of patients with hemiplegia. Methods Ten patients with stroke were randomly allocated to either a closed kinetic chain exercise (CKC) group(n=5) or an open kinetic chain exercise(OKC) group(n=5). The subjects of each group followed the exercise regimen of their respective groups, and each exercise was performed for 50 mins per day, 3 days per week, for 4 weeks. Assessment was made using Berg Balance Scale (BBS), One Leg Standing(OLS) test, and Timed up and go(TUG) test. The 2 groups were assessed twice: before and after the intervention. Results The TUG test score was significantly different in the CKC group between before and after intervention (p<.05); however, there was no such deference in the OKC group (p>.05). Further, the scores of the BBS and OLS tests were not significantly different for the 2 groups between before and after intervention (p>.05). The hanges in these BBS and OLS score were not significantly different(p>.05); however, there was a significant difference in the change in the TUG scores (p<.05). Conclusion On the basis of the results of this study, we found that the closed kinetic chain exercise is more effective in improving the walking ability and dynamic balance in patients with stroke. Future studies are warranted in this regard.

Objective of this study was to investigate adsorption characteristics and kinetic models of $NH_4-N$ to biochar produced from rice hull in respective to mitigation of greenhouse gases. $NH_4-N$ concentration was analyzed by UV Spectrophotometer. For the experiment, the soil texture used in this study was sandy loam soil, and application rates of chemical fertilizer and pig compost were $420-200-370kgha^{-1}$ (N-P-K) and $5,500kgha^{-1}$ as recommended amount after soil test for corn cultivation. Biochar treatments were 0.2-5% to soil weight. Its adsorption characteristic was investigated with application of Langmuir isotherm, and pseudo-first order kinetic model and pseudo-second order kinetic model were used as kinetic models. Adsorption amount and removal rates of $NH_4-N$ were $39.3mg^{-1}$ and 28.0% in 0.2% biochar treatment, respectively. The sorption of $NH_4-N$ to biochar was fitted well by Langmiur model because it was observed that dimensionless constant ($R_L$) was 0.48. The maximum adsorption amount ($q_m$) and binding strength constant (b) were calculated as $4.1mgg^{-1}$ and $0.01Lmg^{-1}$ in Langmuir isotherm, respectively. The pseudo-second order kinetic model was more appropriate than pseudo-first order kinetic model for high correlation coefficient ($r^2$) of pseudo-second order kinetic model. Therefore, biochar produced from rice hull could reduce $N_2O$ by adsorbing $NH_4-N$ to biochar cooperated in sandy loam soil.

PURPOSE: The purpose of the study was to determine the effects of close kinetic chain resistant exercise of lower extremity on the gait with stroke patients. METHODS: The subjects were 50 patients who were diagnosed with cerebrovascular accident. They were randomly assigned either to a close kinetic chain resistant exercise of lower extremity group (study group)(n=25) or open kinetic chain resistant exercise of lower extremity exercise group (control group)(n=25). Gait abilities were measured by using Timed Up & Go (TUG) test, Functional Gait Assessment (FGA) and spatio-temporal gait variable that were velocity, cadence, stride length, double limb support by 3 axises wireless accelerometer and sway angle of center of mass by same instrument. RESULTS: Study group and control group before and after the intervention there were significantly difference in TUG, FGA, spatio-temporal gait variables and sway angle of center of mass (p<.05). There were significantly different between study group and control group for all variables at post-exercise. CONCLUSION: When all is said and done it is expected to be used as a method for the treatment and prevention in the process of rehabilitation of patients with stroke. In its final analysis when applying resistant exercise of lower extremity to stroke patients' gait, close kinetic chain is more effective than open kinetic chain.

The kinetic typography animates the static text and it will enable the delivery the opinion and emotion, but we should use professional software or do complex coding precess to create a motion into an existing static text. In this paper, we propose the primitive motion API which is the way to configure the kinetic typography easily by adding a motion into the static text. In the pursuit of this purpose, we analyzed the movement of the text, defined the underlying levels of the movement and designed the primitive motion API to express the kinetic typography promptly. Furthermore, we verified the performance of the primitive motion API by testing the usability. Using the primitive motion API to implement the kinetic typography explicitly might substitute for tedious coding process and usage of the existing professional software so it makes anyone be able to apply the kinetic typography in a variety of applications.

A bulk amorphous NiTiZrSiSn powder produced using an inert gas atomization was sprayed by kinetic spraying process that is basically a solid-state deposition process onto a mild steel substrate. They were successfully overlaid onto the mild steel substrate. In order to evaluate the tribological behavior of the kinetic sprayed NiTiZrSiSn BMG (Bulk Metallic Glass) coatings, a partially crystallized coating and a fully crystallized coating were prepared by the isothermal heat treatments. Tribological behaviors were investigated in view of friction coefficient, hardness and amorphous phase fraction of coating layer. Surface morphologies and depth in the wear tracks were observed and measured by scanning electron microscope and alpha-step. From the examination of the scratch wear track microstructure, transition from the ductile like deformation (micro cutting) to the brittle deformation (micro fracturing) in the scratch groove was observed with the increase of the crystallinity.
