As the tendency of children's overdependence on smart phones increased, it was obligatory to carry out preventive education more than once a year in kindergarten and day care center, but there is no specific guidance on contents and method of preventive education. This is due to the lack of prior studies on the actual use of smartphones and the influence variables of infants and young children. The purpose of this study was to investigate the effects of use time, frequency of use, and sociological background variables on the actual situation of smartphone usage and overdependency on smartphone among 3-5 year old children nationwide. For the analysis, the frequency of the use of smartphone for 3-5 year old children was analyzed by frequency analysis, and the influence variables were correlated and multiple regression analysis. Research shows that smartphone overdependence of 3-5 year old children have an influence on the use time and frequency of use. The results should include content that restricts the use time and frequency of use of smartphones and prevention education programs for 3-5 year olds and young children. Suggesting a need for a transition to the educational method used.

The purpose of this study was to analyze the EEG according to the elderly's tendency to be addicted to smartphone games. We compared the effects of smartphone addiction on mental health such as brain waves, sleep problems and depression through comparative analysis of asymmetry and connectivity in quantitative EEG results. The study participants were two elderly people who were addicted to smartphone game and one elderly person who did not use smartphone (Ed- to confirm: only 3 participants?!). The participant's addiction tendency of smartphone was measured by using the smartphone addiction scale and EEG (QEEG) was used for EEG analysis. The results are as follows. First, the brain waves of elderly people and smartphone non-user elderly who showed symptoms of immersion and smartphone game showed a difference in asymmetry in both opening and closing anisles. Second, there were significant differences in the openness and the anxiety of the elderly who were immersed in the mobile phone and the elderly who did not use the smartphone. Through this, it is also meaningful to explore the relationship between senile cognitive impairment and smartphone use by exploring the effect of smartphone game use on brain cognitive function through comparison of EEG analysis.

This study tried to understand the structural relationship of consumer characteristics on consumer emotions and satisfaction in online shopping. First, consumer characteristics derived various tendencies through previous studies. Next, consumer emotion was defined as positive and negative emotions in the six purchasing processes from information search to use, and satisfaction was defined as the overall satisfaction of the purchasing experience. To this end, this study measured consumer satisfaction and positive/negative emotions in the six consumption processes in their 20s and 40s with online clothing shopping experience within the last month. Finally, structural equation modeling(SEM) was conducted. As a result, the model fit was good, and impulse purchase tendency, conspicuous consumption tendency, innovation tendency, and trendy shopping tendency only affected negative emotions. On the other hand, it was confirmed that information search tendency, hedonic shopping tendency, and economic shopping tendency directly affect positive emotions and indirectly affect consumer satisfaction. Through this, implications for improving the consumer experience in online shopping were presented by identifying consumer characteristics and enhancing consumer emotions.

The purpose of this study was to examine the effect of individual tendency of individualismcollectivism and the type of incentive system on pay satisfaction. Data were collected from 243 workers employed in a variety of organizations and a hierarchical regression and MANOVA was conducted to test hypothesis. The results of regression indicated that the interaction between the type of incentive and tendency of collectivism has positive influence on pay satisfaction. In addition, the results of MANOVA indicated that the interaction between individual tendency of individualismcollectivism and the type of incentive system has significant effect on pay satisfaction Specifically, the tendency of individualism has positive influence on the pay satisfaction under the individual incentive condition. However, the tendency of collectivism has negative influence on the pay satisfaction partially under the individual incentive condition. In addition, the tendency of collectivism has positive influence on the pay satisfaction under the group incentive condition. These results suggest that careful consideration in the organization need to decide for the use of individual incentive system, when we regard the Korean culture as high tendency of collectivism. In other words, individual incentive system may could not provide pay satisfaction to the employees who have high level collectivism. However, to generalize these results, more studies were examined in the future.

The purpose of this study is to the design tendency expression of contemporary architectural matter, I can find out how the architecture is represented using the surface of building in its autonomy. I study backgrounds of contemporary architectural matter, method and their natures. In this case, i can notice that 'framework-dressing' method formed a objectified tectonic system, while it supplied arts with room that they hold priority to architecture. So it makes me find that contemporary architectural matter resided in relationship complicated between things and events. Also, this study on analyzing spatial effect by the figurative language derived by researching the dadaisme, pop art, kinetic art, video art hit In conclusion, analyzing the recent experiments in the expressive qualities of exterior skin, in their use of materials, methods of construction and visual effects, it can be argued that the new skin is inclusive of times, and has autonomic, constant and tactile features. Base on their immaterial vocabularies - limits, material, mouvement, media - these could be characterized as vibrant plates.

The Elastic modulus depends on the elastic property of composition materials, the gravity of aggregate, the bond strength of binder, the usage and quantity of admixture, curing and measuring method, etc. Accordingly, the aim of this study, by manufacturing concrete of practical high strength range(600~ 1000kg/$\textrm{cm}^2$) with the specific cement and mineral admixtures, is to compare elastic modulus with the existing equations and also to estimate elastic property of use materials. As a result, it could be confirmed that the existing equations which were proposed by the ACI 363, CEB-FIP Code, and New-RC have a tendency to the overestimation in general. However, it could be confirmed that the KCI-96 and Norwegian NS 3473 equations are closed to measuring results, and that the elastic modulus property have a different tendency due to types of cements.

The direct injection stratified charge(DISC) engine enhances the fuel tolerance and the antiknock tendency. This enhanc3d antiknock tendency allows use of a higher compression ratio which results in higher thermal efficiency. But its actual utilization is prevented by high emission combustion time and wall quenching will be the main causes of increasing unburned hydrocarbons in DISC system. In order to solve this problem, small aount of hydrogen was added to the charging air or injected fuel. The effects of hydrogen addition were examined experimentally by radial fuel injection using a pancake-type constant volume bomb. In case of the hydrogen addition to the charge of air, the combustion the amount of hydrogen. In case of the hydrogen addition to the fuel, the combustion pressure was significantly increased.

The language socialization approach states that novices are socialized into cultural norms through participating in routine, repeated interactional acts and sequences (e.g., Ochs & Schieffelin, 1984; Ochs, 1988; Schieffelin & Ochs, 1986a; 1986b; Watson-Gegeo & Gegeo, 1986). One of the cultural norms or dominant epistemological orientations in American culture is the tendency to avoid the overt display of power asymmetry in novice-expert relationship (Ochs & Schieffelin, 1984). This study examines how this cultural preference is reflected and encoded in ESL teachers' use of routine discourse patterns in corrective sequences. Eight hours of ESL classes taught by three Caucasian teachers born and educated in the U.S. were analyzed for the study. The analysis showed that the cultural tendency in question is keyed and indexed in the teacher's routine corrective discourse patterns in the form of various questioning, elicitation, and mitigation practices. Findings support that teachers' routine classroom discourse practices represent their cultural ideologies and transfer these cultural predispositions to second language learners and that they possibly socialize the learners into the target language-oriented beliefs.
