The objective of research was to explore the effects of Kinesic taping treatment on Kayaker's athletic performance and muscle fatigue variable. In order to accomplish such study objective, this study employed 8 ordinary university students and 8 university kayaker's as study subjects. The athletic performance records and blood lactate were analyzed before and after Kinesic taping treatment (KTT). Kinesic taping treatment was applied to the regions of agonist such as vastus medialis muscle, Latissimus dorsi muscle, Trapezius muscle, Biceps brachii muscle, and Triceps brachii muscle, which are major muscles for Kayaker's. Records for rest heart rate, athletic performance and blood lactate were measured upon 200m and 500m distance exercise using kayak ergometer. Data were analyzed by SPSS 19.0 using paired t-test and one-way repeated ANOVA at significant level of a = .05. First, performance records of 200m paddling kayak showed that the ordinary university students had a mean score of 60.13 second before and 58.75 second after kinesic taping treatment. University kayakers had a mean score of 58.75 second before and 53.0 second after kinesic taping treatment. Both groups had significant differences between before and after KTT in the athletic performance. In addition, levels of blood lactate showed that the ordinary university students had a mean score of 5.89mM before and 8.90mM after KTT and university kayaker's had a mean score of 5.79mM before and 8.48mM after KTT. The ANOVA showed that the level of ordinary university students' blood lactate was significantly higher than university kayakers only after KTT. Second, performance records of 500m paddling kayak showed that the ordinary university students had a mean score of 2.90 minute before and 2.77 minute after KTT and university kayaker's had a mean score of 2.30 minute before and 2.20 minute after KTT. Both groups had significant differences between before and after KTT in the athletic performance. Moreover, only university kayaker's had a significantly higher performance record than the counterpart. Levels of blood lactate showed that the ordinary university students had a mean score of 7.71mM before and 8.85mM after KTT and university kayakers had a mean score of 8.09mM before and 8.45mM after KTT. However, such a level of increase had no significant difference between the groups

Objectives: This study was carried out in order to evaluate the overall process that the caregiving stress of parents of adult children with developmental disabilities affected their life satisfaction through the levels of family resilience, and coping styles on the basis of stress-coping-adaptation model of Lazarus and Folkman(1984). Method: For this purpose, the structured survey was conducted by 394 parents of adult children with developmental disabilities. The data was analysed by AMOS 20.0 version. Results: The findings can be summarized as follows: First, the structural equation model(SEM) analysis was conducted in order to examine the various paths that parents' caregiving stress affected their life satisfaction. The model's goodness-of-fit was fine($x^2=225.20$, df=95, p=000. RMSEA=.06, TLI=.95). There were significant relationships between caregiving stress and family resilience(${\beta}=-.36$, p<.001), emotion-focused coping style(${\beta}=.47$, p<.001), life satisfaction(${\beta}=-.53$, p<.001). Second, family resilience and emotion-focused coping showed mediating effects on the relationship between caregiving stress and life satisfaction. Conclusions: The strategies for enhancing family resilience and social services for applying effective coping methods should be expanded in order to diminish the caregiving stress of parents of adult children with developmental disabilities.

This study aimed to examine the mediate effects of game addiction on the delinquency among school adolescents. In order to achieve the research purpose, secondary data was used which is the data by 8,516 people researched for 'A study on mental health improvement policy for children and adolescents II' among NYPI cross-sectional analysis provided by Korean Children Adolescents Data Archive and the collected data was analyzed using SPSS 21.0 and AMOS 21.0. The major findings were as follows. First, the better relationship with family and teachers led to lower level of game addiction and delinquency. However, in terms of relationship with friends, better relationship led to lower level of game addiction but higher level of delinquency. Second, as a result of verifying mediator effect of game addiction by decomposing the effects of relationship with family, teachers and friends on delinquency, they all demonstrated negative mediator effect. Based on the results I discussed social welfare intervention methods for game addiction in order to understand and prevent school adolescents' delinquency.

Second-order nonlinear optical(NLO) materials have been extensively studied for applications in photonic devices, such as frequency doubling and electro-optical(EO) modulation, because of their large optical nonlinearity, excellent processibility, low dielectric constant, and high laser damage thresholds. The poling behaviour of NLO chromophore in organic/inorganic matrixes showed the randomization of poled NLO chromophore in the absence of poling Held. The liquid crystal molecules in a droplet showed a long-range orientational order along a director. Therefore, liquid crystal effects on poling behaviour of NLO chromophore dispersed in organically modified inorganic sol-gel materials were investigated. Using sol-gel process for the development of NLO material has received increasing attention, Organically modifked inorganic NLO sol-Eel materials are obtained via incorporation of the organic NLO active chromophore into an alkoxysilane based inorganic network. One of the most important thing in this works was that tetraethoxysilane(TEOS) and methyltrimathoxysilane(HTMS) were used as precursor followed by hydrolysis and condensation without using any acidic catalyst during the process. The NLO chromophores in the liquid crystal nanodomains were well mixed with I/O hybrid matrix, deposited on transparent ITO-coated glasses. The poling behaviour of liquid crystal effects of NLO chromophore dispersed in I/O hybrid matrix were investigated by UV-vis spectroscopy. Size distribution and morphology of the NLO chromophores doped in the liquid crystal nanodomains dispersed in I/O hybrid matrix were investigated by SEM.

The purpose of this study was to investigate ego-resilience and social adaptability of the children and adolescents in institutional care. The study also investigated the protective factors and the risk factors on ego-resilience and social adaptability and their relationship. The subjects in this study were 140 children and adolescents in institutional care. The research data were analyzed using Frequency, Pearson's Correlation, Stepwise Multiple Regression Analysis and T-Test in SPSS WIN 10.0 program. The major findings were as follows. First, ego-resilience of the children and adolescents in institutional care was related to locus of control, depression and anxiety and unsatisfaction of institutional care. Result of stepwise multiple regression analysis showed that depression and anxiety and locus of control in the order had significant effects on ego-resilience. Second, social adaptability of the children and adolescents in institutional care was related to social support and parent-child bond. Unsatisfaction of institutional care and social support in the order had significant effects on social adaptability by stepwise multiple regression analysis. Third, the children and adolescents who had higher level of ego-resilience reported better social adaptability. The overall research results revealed that the risk factors such as unsatisfaction of institutional care and depression and anxiety than the protective factors had more significant effects on ego-resilience and social adaptability of children and adolescents in institutional care. This finding suggested that elimination of risk factors rather than development of protective factors was a more important task for the welfare of children and adolescents in institutional care.

Unlike pure art such as painting and sculpture, dressmaking , a field of special plastic art, is characterized by its physical and functional nature. Having an inseparable relation with form, it is a field of art expressiion the human innersense of beauty in correlation with other various fields of art. In this respect, I think it should be necessary for us to study the forms of art from the past in order to study the forms of art from the past in order to study the correlations and mutual influencies between forms of pure art and dressmaking and to understand modern dressmaking from the standpoint of art. In this context, this study is an attempt to analze how the form and characteristics of OP ART , which represents the trends of the 1960's is embodied in modern dresses. The results are as follows : Fist , the expression of OP ART in dresses have visual effects harmonizing with bodily movements and , also, expanded the range and dynamics of expression which resulted from the introduction of visual phenomena in a fresh new sense by not limiting itself to the suggestion of patterns of OP ART. Second, OP ART paintings expressed the mobility and rhythimicity of a body in a limited space in a two-dimensional plane way of expression . When a dress is worn, however, it expands such mobility and rhythmicity in a cubic , three-dimensional way, maximizing the effects of , and boldly expression, OP ART, it can also create a new silhuette and ability of formation by seeking an open expression of OP ART rather than an expression of OP ART it self , due to the infinite possibility and unpredictability by the dynamics of movements and the elements principle of designs. Third , by applying the patterns of OP ART to dresses, we can obtain special visual effects of design, cover up the body's weak points, and create a desired three -dimensional sense by highlighting the beauty of the body's curved lines. Although modern dresses and OP ART are different genres of art, both have something in common in their pusuits. Since there is a infinite possibility in OP ART, there should be continuous attempts to combine dresses and art satisfying the sense of the times, which will lead dressmaking to a higher-dimensional dressmaking plastic art.

In order to present the geometrically nonlinear F.E. formulation of space frames, two beam/column elements including the effects of transverse shear deformation and bending stretching coupling are developed. In the case of the first element (Finite segment method), the tangent stiffness matrices are derived by directly integrating the equilibrium equations, whereas in the case of the second element (Finite element method) elastic and geometric stiffness matrices are calculated by using the hermitian polynomials including shear deformation effect as the shape function. Both elements possess the usual twelve degrees of freedom. Also, the bowing function including shear deformation effects is obtained in order to account for the effect of shortening of member chord length due to the bending and torsional behavior. Numerical results are presented for the selected test problems which demonstrate that both elements represent reliable and highly accurate tools.
