The purpose of this study is to review the role of dragging in dynamic geometry environments. Dragging is a kind of dynamic representations that dynamically change geometric figures and enable to search invariances of figures and relationships among them. In this study dragging in dynamic geometry environments is divided by three perspectives: dynamic representations, instrumented actions, and affordance. Following this review, six conclusions are suggested for future research and for teaching and learning geometry in school geometry as well: students' epistemological change of basic geometry concepts by dragging, the possibilities to converting paper-and-pencil geometry into experimental mathematics, the role of dragging between conjecturing and proving, geometry learning process according to the instrumental genesis perspective, patterns of communication or discourse generated by dragging, and the role of measuring function as an affordance of DGS.

This aim is to explore the change of lifestyle caused by climate change and develop available adaptation policies against climate threats in Central Asia with the perspective of nomadism, which depends entirely on natural ecosystem. This article also attempts to pinpoint the dynamics between nomadic lifestyle and adaptation options for the resilience of nomadic community against climatic change threats. The adaptation options and opportunities as well as the impacts of land use change and nomadic pastoralists' lifestyle caused by climate change cannot be overemphasized. We suggest that nomadic lifestyle may aggravate the degree of vulnerability to climate change threats, whereas the capacity of nomad to successfully adapting to new environment in developing countries can be superior to that of settler lifestyle in one place in developed countries.

The purpose of this study is to investigate the antecedents of city brand personality and those effects on city brand personality and attitude toward city. This study attempts to confirm dimensions of city characteristics and city brand personality, and analyze the structural relationships among the city characteristics, city brand personality and attitude toward city. The result showed that various characteristics of city (culture and historic characteristics, life stability, facility convenience, economic factors, the image of city appearance, nature friendly characteristics) influence city brand personalities. In addition, city brand personalities (vivid personality and stable personality) are positively related to attitude toward city and mediated between the characteristics of city and attitude toward city.

The purpose of this research is both to analyse the dynamics of welfare pluralism in the personal social service policy for elderly British people and to provide policy implications based on analysis of the post World War II time era up until the end of the New Labour Government. Content analysis of government and parliament reports, minutes, scripts for party conferences, legislations, declassified government documents, and institutes' reports of the Conservative, Labour, and New Labour Governments from 1945 to 2010 shows that the governments played only assistive roles in welfare pluralism at any given point in time. The negative experiences of elderly British can be attributed to the unbalanced structure of roles held by public and private institutions for personal social services. They ultimately have important policy implications for the foundation of welfare pluralism in elderly Korean community care by the Moon Jae-in government.

This study empirically verified the effect of environmental dynamism on changes in the dynamic and operational capabilities of an enterprise and its innovation performance. With the aim of quantification, the concept and definition of each capability were defined as a hierarchical structure of dynamic and operational capabilities. Five research hypotheses were established through prior research on dynamic capabilities, operational capabilities, innovation performance, and environmental dynamism. For empirical analysis, the hypotheses were verified based on surveys from 300 Korean manufacturing companies. It was shown that Dynamic capabilities had a positive relationship with operational capabilities and operational capabilities had a positive relationship with innovation performance. And it was shown that operational capabilities had a positive relationship with radical innovation in business groups with high environmental dynamism while operating capabilities had a positive relationship with gradual innovation in business groups with low environmental dynamism. Also, the moderating effect of environmental dynamism was not significant in the relationship with dynamic capabilities on operational capabilities. This study is meaningful in that it lays the groundwork for empirically verifying the dynamic capabilities of an enterprise by embodying its dynamic capabilities and operational capabilities into processes, and verifies the effect of environmental change on its capabilities and innovation performance. And it has implications to suggest how an enterprise should transform its capabilities to sustain its competitive advantage in a rapidly changing environment.

태깅은 웹 2.0의 핵심 기술 중 하나로, 매우 유연하고 역동적인 분류 체계를 제공한다. 하지만 유연성과 역동성의 확보에 의해 계층 구조나 연관 관계와 같은 태그의 관계성이 부족하거나 존재하지 않는 한계점을 가지고 있는 것 또한 사실이다. 이런 한계점을 보완하기 위한 방법으로 계층 관계를 형성하기 위한 계층 클러스터링 방법과, 연관 관계를 형성하기 위한 협업 필터링 방법이 존재한다. 이 두 가지 방법은 태그의 관계성을 제공하지만, 연관 관계와 계층 관계 중 하나만 제공한다는 단점을 가진다. 본 논문에서는 태그 검색 시 연관 관계뿐 아니라 계층 구조의 탐색을 제공해주기 위한 태그 클러스터링 알고리즘을 설계하였다. 제안한 알고리즘은 사용자 태그셋을 활용하여 태그의 유사성을 계산하는 방법을 제시하고, 기존의 시각화 방법(태그 구름)과 다른 새로운 형태로 시각화 할 수 있는 결과 데이터를 제공한다.

The aim of the study is to create a theoretical model and hypotheses on competitive advantages of exporting SMEs. For this we have proposed an integrated model in which learning competences and dynamic capabilities should have an influence on competitive advantages of the SMEs. This study have examined the influence of integrating and reconfigurating capability respectively. As a result, the learning competences had positive influences in dynamic capabilities and to the cost and service competitive advantage. To integrating capabilities had positive influences in competitive advantage. Besides, dynamic capabilities playing significant intermediate role only for the cost advantage through the analysis of intermediate effects of learning competence to the dynamic capabilities.

This study aims to identify the change of customer participation(CP) which is essential to the service industry as the relationship between the customer and the employee develops. The latent growth modeling analysis based on the longitudinal data is utilized to examine the pattern of the change. This is based on the fact that CP needs to be understood in the relationship and is to confirm the change in CP by the development of the relationship. Given the dynamics of the relationship, we intend to overcome the limitations of previous cross-sectional researches by revealing the trajectory of CP in the relationship through the longitudinal data. We also want to examine which variables in the relationship can facilitate changes of CP. Research has shown that CP is significantly changed with the development of the relationship when we analyzed it through latent growth modeling. This confirms that CP needs to be understood in the relationship. In addition, 'relationship proneness' variable and 'dependence to provider' variable have positive effects on the initial values of CP, but they have not been established to promote the changes of CP. Consequently, when considering the dynamics of relationships, it is important to recognize that CP is also dynamic. This study sought to get out of the cross-sectional and fragmented understanding of CP that is dynamic. Through this, we would like to propose the successful operation of the customer management program of service firms in relation to CP. This will lead to the success of service encounter where appropriate CP levels at each stage of relationship development can be achieved.

This paper was to investigate the relationships between the types of incest and family dynamics. 9 incest cases were collected from the Department of Social Work, Seoul National University Children's Hospital and an adoption agencies. The study cases were categorized into three types of incest, father-daughter incest, mother-son incest, sibling incest. The father-daughter incest families revealed various dysfunctional family dynamics such as sociopathic father, psychologically and physically absent mother, pseudomature child, and lack of communications among family members. In mother-son incest families, the fathers were absent and the mothers abused their sons as an outlet for their sexual desire, which was most pathological, among three types of incest. Sibling incests were characterized by the absence of parental supervisions and appropriate emotional care, and younger sibling becoming a sexual outlet of older sibling. It is evident that the incest does not occur simply because of pathology of one family member but because of family dystunction. Therefore the incest was a kind of 'family disease', and the focus of treatment should be on the whole family.

As Digital technology developed, drawing animation, using traditional production method which expresses many feelings with drawn lines loses the youth group, the primary audience, to the realism of the digital cinema. Drawing animation, which drew attention of the youth by the spectacles in the film such as hectic pace, dynamics and punch, declined for a while. However, it has been developed a way to express pace and dynamics of its own by establishing an effective directing method, which combines digital technology as it is needed. This study has a purpose to investigate what causes the dynamics and feeling of fast movement of the character in Japanese limited animation. Though some action-animated films that heroes with supernatural powers take the leading role that feeling of velocity and dynamics are emphasized we compare the directing method before and after the introduction of the digital technology. This research reaches the conclusion by factoring each Bergson and McLuhan's discussion to the intervention of indexical signs and the audience's participation according to skipping technique. This study has a significance of researching the element of drawing animation that maximizes the expansion of the senses by defying the limitation of the law of physics through its unique way of directing together with growth of the hero films, which will continue.
