Students with learning disabilities need special education programs. In the traditional class, those students may not be satisfied with their studies. Thus, it is important to provide individualized class for those students. Classes using smart devices may give one of the solutions for individualized class. Unlike the typical mathematical problems, written problems require students to use various cognitive strategies, mathematical reasoning, inference ability, and so on. In this sense, written problems are good tools to develop the logical minds for students with learning disabilities. In this paper, a WOE-based smart learning system is proposed to help those students develop learning abilities. The proposed system has the following characteristics. First, students can learn naturally problem-solving abilities by following the work-out examples given from experts. Second, the proposed system can invoke motivation and interests of students using attractive icons and guidance rules provided with smart phone. Third, the proposed system can provide self-directed study for those students. The proposed system is applied for some students with learning disabilities. The following results are obtained. First, the individualized study can be possible since the system can provide continuous feedbacks and level-differentiated classes. Second, students can increase written problem solving abilities with natural understanding of study contents from smart phone. Finally, satisfaction, study motivation, and self-concept of students are increased through their successful experience during study processes.

This study analyzed the 2009 revised curriculum 6th grade math geometric domain and developed virtual operation tool contents based RME theory. These materials were examine to find out how to effect on the spatial sense and mathematical attitudes by applying it to teach the 6th grade students. The results were as follows. First, it is more effective for improving spatial sense to study mathematics based RME theory with virtual operation tool contents than normal one. This means that mathematics study based RME theory with virtual operation contents overcomes the limitations of flat learning environment. And it is great educational and effective method for students to improve their spatial sense. Second, it is more effective for improving mathematical attitudes to study mathematics based RME theory with virtual operation tool contents than normal one. This means that Mathematics study based RME theory with virtual operation contents makes student more participate learning actively. It helps the students who have passive learning habits to have self-directed learning habits, ability to cooperation and communicate. The results of this study suggest that mathematics study based RME theory is very helpful for student to improve their spatial sense and have positive effect on self-concept in mathematics, attitudes toward mathematics and improving study habits in mathematical attitudes.

This study suggested implications by dividing the concept of brand origin into national image and manufacturing capacity image, verifying the direct impact of these variables on brand trust and brand loyalty, and verifying the difference between products with the effect on brand trust of brand origin, which is the result of verification. The specific implications of this paper are as follows. First, brand origin does not directly affect brand loyalty, but it can have a direct impact on the preceding variable, brand loyalty. This study may conclude that it is desirable to define the factors that affect the purchase selection indirectly through the assessment of product properties or positive effects on brand image rather than having a direct impact on product purchase or selection. Second, the difference in brand origin influence by product characteristics was very evident. Past studies were limited to a few products, so pan-product testing was not conducted, and the empirical power was judged to be limited, so this study included a variety of products and tried to detect differences between products through actual empirical research. Involvement and self-congruity have been presented with results that can be judged as important variables for brand origin to affect brand performance and variables. Looking at the role of the brand origin for each product characteristic by distinguishing between product characteristics and whether or not products related to quality, history, authenticity, etc., the product recognized as high quality and the product recognized as having high integrity showed higher effect of the brand origin, but history was a product characteristic that did not show the effect of the brand origin.

The ultimate purpose of psychotherapy is to identify covert causes of a psychological problem and then to modify and change the causes. The goal of this study is also to make contribution to SNS addiction intervention program development through exploring the covert causes of SNS addiction which recently became social issue. Previous research identified such overt causes of SNS addiction as maladaptive self-concept (e.g., low self-esteem), maladaptive personality (e.g., strong narcissism) and strong negative emotions (e.g., high level of anxiety). Based on previous research, the study explored early maladaptive schema (i.e., cognitive dimension) and emotion dysregulation (i.e., emotional dimension) as the covert causes of SNS addiction and conceptually developed psychological maladaptive mechanism of 'early maladaptive schema ${\rightarrow}$ emotion dysregulation ${\rightarrow}$ SNS addiction.' As a result of a survey with respondents in their 20's who are at high risk for SNS addiction, the mechanism was confirmed for females. However, a significant relationship of 'early maladaptive schema ${\rightarrow}$ SNS addiction' was found for males. The findings offer an implication that interventions of early maladaptive schema for males and females in their 20's and interventions of emotion dysregulation for females in their 20's can fundamentally help cure their SNS addiction.

Determinism and compatibilism have thought that libertarianism contradicts the scientific view. This paper demonstrates that the hypothesis that free will exists does not cause any problems and contradictions, while maintaining pro-scientific view. Rather, determinism lacks scientific and demonstrative bases. At first, I reject dualistic self by assuming identity theory of the self and physical body & brain. Free will is a functional concept or property that can have multiple realization. Therefore we can recognize whether aliens or robots have free will through observation on their acts. 'Free will' is a functional kinds term like 'digestion'. As we know we have digestive function, we can know that we have free will even before knowing the necessity of its existence by understanding micro structure of human free will. The judgement that an individual has free will function depends on whether it has particular actions. Those actions are controlling and restraining actions in context, predicting future, making elaborate conditional sentences, etc. Real being of free will is the physical occupant of the function that makes those actions. Determinism is based on various kinds of misconceptions and misunderstandings. Determinists often confuse necessity of physical law and determinism. Another decisive misunderstanding is that free will postulates same conditions and different results from the same point of time. However, free will postulates that the two points of time are different. Because determinism is unnecessary redundant hypothesis influenced by religions, according to Ockham's Razor, determinism should be eliminated.

This study aimed at the identity of the landscape architectural award, which is the highest authority award system in landscape architecture; the establishment of cooperation between the landscape architecture and urban public sector, which deals with infrastructure is significantly requested nowadays. The identity characteristic of a detailed concept which configures the sameness in the shape of inner self-cognition and individuality as external and correlative cognition are utilized as the research methodology, and the findings are summarized as follows. The Korean Landscape Architectural Award holds an internal value as the only award in landscape architecture that is granted municipalities and public agencies. However, when it is compared with several correlated award systems, the vulnerable sides such as short origin and partly limping in terms of sustainability, the possibilities of losing the interest in the public sector due to management's reform program and insufficient participants and responses regarding social authority have been found. In addition, according to the today's paradigm tha taims for green cities, the aspect that shares the large portion with the values set by detailed categories of city planning that enforces metropolis awards is also in the spotlight. Hence, the landscape architectural award should construct specialization and development strategies by strengthening the superiority compared with the city award in the field of city planning. In other words, the Ministry of Land, not limited to the systematic cooperation with various administrative areas will be strengthened and it will communicate with the aspect that reinforces characters as an academic and practical area that covers various districts and disciplines. Thus, the identity is directly connected to the landscape architectural award's competitive reinforcement as a detailed characteristic variously combined, and it requires huge interest and discussions regarding internal and external landscape architecture areas and the democratic public discussion process.

Due to the development in industrial technology, changes in consumer behavior and aggravating competition within the industry, it is growing only harder every day to build up a strong brand power. Besides, a brand is supposed to age as time goes by, following a brand life cycle, as it is not a solid, immutable asset but something of a living creature. Therefore, self-renovation and revitalization efforts are needed, in order to incessantly confirm the self existence through the relationship with the consumer. In sum, revitalization operation is needed to renew a brand that has grown trite in the passage of time or due to the change in market condition, so as to bring it back anew to the consumers. This study did not stop at measuring the effect of a design renewal as a short-term assignment, but focused on the long-term brand management following the brand life cycle and aimed to define the effective timing and method of revitalization by comprehending the analysis results of consumer consciousness by analyzing the successful cases of brand revitalization and selecting the research analysis targets. As a result, this study proved that a properly-timed brand revitalization efforts in order to cope in advance with predictable changes in environment, can significantly prevent any drop of brand equity from occurring and then extend the brand life cycle. Also, this study could find that a brand revitalization is not a mere concept of a strategy for a short-term sales increase, but should be a long-term strategy to manage a brand, which must be practiced continuously in the time when the brand life cycle curve starts to fall. This research could also confirm that a superficial design renewal, which changes only the packaging of a brand, peformed in short-term haste, is not of help at all.

As the necessity of humanistic education has recently been socially emphasized, aptitude and character test has been conducted in the stage of training instructors to focus on making them equipped with proper ability of humanistic education. Especially, considering characteristics of students in specialized high schools with stronger negative concept of ego along with higher proportion of students looking for job in early ages compared to regular high schools, instructors in specialized high schools need to pay more attention on humanistic education of students compared to those in regular high schools. Therefore, this study has developed social emotion learning (SEL) of preliminary teachers in specialized high schools and analyzed the influence of developed programs on characters in teaching positions of preliminary instructors in specialized high schools. In this study, ADDIE model has been used developing SEL programs, and developed programs were comprised of total six sessions. Social emotion learning has been performed on 27 preliminary teachers in experiment group, and regular academic education courses were given on 30 preliminary teachers in control group. At this time, as for class contents, 'self-recognition' has been dealt with in the first and second sessions followed by 'self-management' in the second and third sessions, 'adjustment in relationship' in the fourth session, 'responsible decision making' in the fifth session, and 'personal relationship' in the sixth session. Classes have been conducted for 90 minutes in average. Since intentional sampling method has been used in this study, difference of pre-scores between groups might influence on the difference on post-scores. Therefore, ANCOVA that adjusted the pre-scores to be consistent has been utilized. As a result, there was a significant difference on the post-scores in characters in teaching positions between experiment group and control group.

RBAC(Role based Access Control) is effective way of managing user's access to information object in enterprise level and e-government system. The concept of RBAC is that the access right to object in a system is not directly assigned o users but assigned by being a member of a role which is defined in a organization. RBAC is utilized for controling access range of privacy but it does not support the personal legal right of control over information and right of limited access to the self. Nor it contains the way of observation of privacy flow that is guided in a legal level. In this paper, extended RBAC model for protecting privacy will be suggested and discussed. Two components of Data Right and Assigning Data Right are added to existed RBAC and the definition of each component is redefined in aspect of privacy preservation. Data Right in extended RBAC represents the access right to privacy data. This component provides the way of control over who can access which privacy and ensures limitation of access quantity of privacy. Based on this extended RBAC, implemented examples are presented and the evaluation is discussed by comparing existed RBAC with extended RBAC.
