This study constructs an integrated model for university students' smart phone cyber bullying and tests interaction effects between causal and control factors. Causal factors include low self-control, differential association with cyber bullying peers, and victimization experiences; and control factors include internet ethics, perceived certainty of formal punishment, and bond to parents. This study focuses on examining how internet ethics buffers the effect of causal factors in cyber bullying. Results show that both differential association with cyber bullying peers and victimization experiences have significant effects on cyber bullying. And among the control factors, internet ethics only has a negative direct effect on cyber bullying. In addition, it is found that there are significant interaction effects between two causal factors - differential association with cyber bullying peers and victimization experiences - and internet ethics. It is also shown that there is a significant interaction effect between victimization experience and bond to parents, but a perceived formal punishment has no significant control effect. It is revealed that internet ethics is a main control factor in buffering the effects of causal factors in cyber bullying.

Virtual Reality fields see the popularization era. Desk-top VR industries are under rapid development, concentrating on various Web VR applications. Performing user navigation in 3D virtual space is a complicate process in which one is looking for a way with understanding logical structures established in a virtual space and noticing established interactions. It is not a process established by a user, but a technical, skillful and conceptual process carefully designed and constructed at the pre-production stage. Therefore, in this paper technical, skillful and conceptual basic theories, related with the interactive navigation in a 3D virtual space, are thoroughly discussed.

This study was conducted to apply occupational reminiscence therapy (ORT) to the elderly diagnosed with mild cognitive impairment (MCI) who reside in the local community and determine its effects on cognitive functions, physical health, communication and interaction skills, and depression. The participants were elderly diagnosed with MCI who visited YW community health center on a regular basis and were randomly divided into an experimental group and a control group. The experimental group received eight one hour sessions of ORT once a week. Individual interviews were then conducted with the participants to determine if an event or activity had been commonly experienced, after which the program was modified and supplemented as necessary by referring to previous programs. The Content Validity Index (CVI) was calculated, and differences before and after ORT's were identified by paired t-tests. Moreover, the Mann-Whitney U-test was conducted to identify differences in variances between groups. Only participants in the experimental group (n=9) reported significant improvements in cognitive function, physical health status, communication and interaction skills, and depression when compared to those in the control group (n=9). Therefore, it is expected that ORT will be actively used as a non-pharmacological intervention for preventing dementia and improving the health of elderly persons with MCI.

This study aimed to investigate the effects of participating in an aerobic exercise program three days a week and 50 minutes a day on dementia related factors and cognitive function in elderly women with mild dementia. For this, among 17 elderly women aged 65 and above, 10 elderly women were randomly assigned to the experimental group and 7 elderly wonmen to the control group. As a result of comparative analysis, conclusions were drawn as follows: There was a significant difference (p<.05) in the DHEA-s change between the two groups according to whether or not the aerobic exercise program was performed. Changes in cognitive function did not show any significant difference in the interaction effects of group, period, period${\times}$group. These results suggest that the aerobic exercise program did not show statistically significant effects on the dementia related factors and cognitive function changes of the elderly women with mild dementia. The reason for this is that the followings should be analyzed in more detail, but the lack of control on the daily life (diet) of the study subjects, which was considered as a limitation in this study, seems to be the biggest cause. Based on the results of this study, we hope that this study will be used as a basic data for improving the quality of dementia.

Rapid development of electronic technology has made it possible to perform various function. But this technology made it increase it's complexity. Therefore, It was important to identify usability problem in interface design. The quality of interface to promote the efficient interaction should be evaluated with regard to users' cognitive characteristics. So, in this paper, washing machine, that is one of the most useful electronic home application was studied menu structure on interface and it's operational states transition. At first, an cognitive menu structure is identified with users' conceptual similarity of the main function of washing machine. Then three washing machines was selected to compare with the cognitive menu structure. And, we were analyzed how operational state of the washing machine was transfered. As a result, we can be revealed that menu operational method based on the cognitive structure was consistent with the user's preferred operational method during the experimental tasks and the users and designers had a different knowledge of an it's function structure. These results will be useful to design the washing machine interface.

There is a close interaction between the linguistic-syntactic representation system and the affective representation system that appear in the mathematical process. On the other hand, since the mathematical conceptual system is fundamentally metaphoric, the analysis of the mathematical concept structure through linguistic representation can help to identify the source of cognitive and affective obstacles that interfere with mathematics learning. In this study, we analyzed the problem-solving protocols of mathematical gifted children from the perspective of cognitive language and meta-affect to identify the relationship between the functional characteristics of the text and metaphor they use and the functional characteristics of meta-affect. As a result, the behavior of the cognitive and affective characteristics of mathematically gifted children differed according to the success of problem solving. In the case of unsuccessful problem-solving, the use of metaphor as an internal representation system was relatively more frequent than in the successful case. In addition, while the cognitive linguistic aspects of metaphors play an important role in problem-solving, meta-affective attributes are closely related to the external representation of metaphors.
