오늘날과 같이 급변하는 사회 속에서 개인 혼자서 모든 일을 처리하기보다는 여러 사람과 함께 열린 사고로 일을 처리하는 것이 훨씬 효율적이다. 학습에서도 마찬가지로 협동학습은 지식뿐만 아니라 인성적인 면에도 영향을 끼치게 된다. 본 논문에서는 구성주의에 입각한 웹기반 협동학습 시스템을 설계 및 구현하여 실제 학습 수업에서 활용한다. 이 시스템에서는 학습내용을 구성하는 부분과 이를 이용하여 학습을 수행하는 부분들이 교수자간 및 학습자간에 협동을 한다. 이는 고차원적인 사고를 요구하는 문제해결학습을 통해 학습자 개개인의 능력을 최대한 개발할 수 있고, 학습 성취감을 증가시킬 수 있다. 또한 그동안 부족했던 웹상에서의 상호작용적인 측면을 강화하여 면대면 교육과 같은 즉각적인 효과도 얻을 수 있다.

일반적으로 인간은 외부로부터 정보의 85% 이상을 '시각'을 통해 얻고 있으며 색(色)-형(形)-Texture(質感)의 순으로 사물을 인식한다. 그래서 인간은 예전부터 위험상황에 대응하기 위해 대상의 정보를 신속하게 전달하는 수단으로 색채를 활용해 왔으며, 안전색채는 이러한 색의 속성을 이용 위험으로부터 안전을 확보하기 위해 적용되어왔다. 현재 안전에 관한 정보를 제공하는 시스템에는 언어나 문자사용을 가능한 한 사용하지 않고 안전표지를 국제적으로 표준화하여 사용하는 것이 바람직하며 실제로 국제표준기구(ISO)가 제정한 '안전색채 및 안전표지(ISO3864)'를 채택하거나 자국의 실정에 맞춰 일부 변경 사용하고 있다. 또한 안전표지는 색만이 아니고 그것을 표시하는 형까지 포함 사용되며 형태는 표시 물건에 따라 다양하며 또한 색채가 일으키는 심리 작용을 이용하여 주의를 환기하거나 위험을 경고하며 위험방지 및 긴급사태에 대한 대응을 목적으로 하고 있다. 안전색채 및 안전표지의 목적은 안전 및 건강에 영향을 미치는 대상물 및 장소에 신속하게 주의를 촉구하는데 있다. 따라서 본 연구에서는 안전색채와 안전표지에 대해 알아보고 이를 사용한 실례를 통하여 안전색채와 안전표지의 색채 및 디자인에 대해 알아보고자 한다.

최근 피싱의 한 유형으로 등장한 파밍은 웹 사이트를 위조하여 개인정보를 탈취하는 공격이다. 신뢰받는 기관(금융, 정부 등)의 사이트로 위장하여 개인정보를 탈취하는 방식은 같으나 차이점은 피싱의 경우 유사 도메인을 이용하는 경우가 많아 사용자가 주의를 기울이면 공격을 피할 수 있다. 하지만, 파밍의 경우 DNS 스푸핑을 이용하여 사용자가 정확한 도메인주소(URL)를 입력 하더라도 공격자가 미리 만들어둔 위장 웹 서버로 접속이 되기 때문에 사용자가 주의 깊게 살펴보아도 공격을 인지하기 어렵다. 본 논문에서는 파밍 공격에 사용되는 DNS 스푸핑에 대해 논의하고 파밍 탐지기법에 대해 소개한다. 궁극적으로는 파밍 탐지기법들을 비교 및 분석한 후 실제 구현을 위해서 극복해야 할 한계점을 알아본다.

The present study aimed to emprically verify the materialistic pursuits process of undergraduates by applying the escape theory of materialism(Donnelly et al., 2016). Among the six steps of Donnelly's model, the first step is percieving that the fall short of high standards of life, as measured by external contingencies of self-worth. The second step is blaming the self for falling short of standards, as measured by self-discrepancy. The third step of high aversive self-awareness is measured by low stability of self-esteem. A total of 465(203 male and 262 female) college students participated in the online survey and the model was tested using structural equation model. We found that the relationship of external contingencies of self-worth and materialism was mediated by self-discrepancy and there was a sequential mediation effect of self-discrepancy and the stability of self-esteem. The direct effect of external contingencies of self-worth on materialism was also significant. This study is meaningful in that it used the escape theory to emprically verify the materialistic pursuit process of Korean undergraduates living in a meritocratic society.

This study aims to study Esping-Anderson's theory of welfare state system, develop a model of welfare state suitable for Korea's situation, and apply it to reality. In this research method, basic research and analysis of ideology is used, focusing on Esping-Anderson's welfare state system theory, and applying it appropriately to the Korean situation. Studies on the model of the welfare state have been studied after the classification of complementary and institutional models asserted by Willensky and Lebo in 1965. In addition, Esping-Andersen asserts three things as a model of the welfare state according to ideology. First, the role of the market is central to the liberal welfare system that best fits the image of classical capitalism, and individualistic solidarity through the market. The role of the state or family, which can be a hindrance, is actually marginalized. In addition, in order to maximize individualistic solidarity through the market, de-commodification in the national domain tends to be minimized. Second, the conservative welfare system has a strong familistic element, so the source of social solidarity is the family, and the state plays a role of supporting and supplementing the characteristics of this family. In the conservative system, de-commodification appears to be high among household heads, or the welfare system takes on a corporatist and nationalistic form, it can be said that these characteristics are reflected. Third, in the social democratic welfare system, the source of social solidarity is the state. Therefore, the role of the state is large, the state has a high possibility of decommodification, and it has the characteristics of substitutes for the family and the market through universalist intervention. This study applies Esping-Anderson's three welfare state models to study a model suitable for the Korean situation. In conclusion, Esping-Anderson's three welfare state models can be classified into a market-oriented model based on a liberal welfare system, a status-oriented model based on a conservative corporatist welfare system, and a solidarity-oriented model based on a social-democratic welfare system, presented a compromise between liberalism and conservatism as a Korean model.

The purpose of this study is to empirically examine a behavior improvement of unethical information sharing through the ethics program in organization. An unethical behavior of information sharing on organization members is to be get to private interests through divulgence of company's confidential information. An unethical information-sharing of individual is the opportunist and selfish behavior for an expansion of social capital and shows a negative ripple effect in organization. When conducting the research methods, the analysis order performs the cluster, discriminant, t-test and multiple regressions. According to the study, There are differences the behavior of unethical information sharing between opportunist and non-opportunist. The opportunist member for unethical behavior improvement required the program operation both value and compliance oriented program. Non-opportunist member required only the value-oriented program. The upcoming research needs to explore both ethics program's frequency and action of a punished person.

This article presents new perspectives for classification of students' mathematical errors on the basis of experiential structuralism. Experiential structuralism's mechanism gives us new insights on mathematical errors. The hard core of mechanism is consist of 6 autonomous capacity spheres that are responsible for the representation and processing of different reality domains. There are specific forces that are responsible for this organization of mind. There are expressed in terms of a set of five organizational principles. Classification of mathematical errors is ascribed by the theory to the interaction between the 6 autonomous capacity spheres. Different types of classification require different autonomous capacity spheres. We can classify mathematical errors in the domain of linear function problem solving comparing cognitive psychological mechanism of experiential structuralism.

Michael Williams, in his paper, rejects the wide-accepted view that Donald Davidson's radical interpretation is a truth conditional account of meaning, and suggests a claim that robust truth in fact does not play any role in Davidson's interpretation and thus interpretation can be in accord with the deflationary theory of truth. In this paper, I will first research the right understanding on the explanatory relations in radical interpretation between truth and meaning, and on that ground, will evaluate the adequacy of Williams' suggestion. My diagnosis is that the acceptability of Williams' idea depends on how we regard the several factors which are crucial for interpretation. Especially I will argue that whether truth condition is regarded as deflationary or inflationary makes difference to the way of understanding radical interpretation, hence the room for taking radical interpretation as deflationary can be in two different ways. Furthermore I will show the same argument can be applied to Williams' another claim that Paul Horwich's use theory of meaning is similar to Davidson's account.

This paper considers some significances and limitations in application of Rawls' liberal theory of justice to conceptualization of environmental and ecological justice. It first reviews Rawls' liberal theory of justice, then examines how his theory of justice considers natural resources and can be applied to develop distributive theory of environmental justice, and finally explores what kinds of problems would be generated when Rawls' theory of justice is to be extended to animals and other natural components. In Rawls' theory of justice the status of natural resources is described as a objective condition for justice, but it is argued that natural resources should be seen as a substantial component of just production and distribution. It also can be stressed that his theory of justice does not secure a just result of resource distribution, even though it has a great significance for just procedure of distribution. Finally, it seems hardly possible to extend Rawls' theory of justice to animals and other natural components to develop a Rawlsian theory of ecological justice, because liberalism and Western tradition of science on the basis of which Rawls' theory of justice has developed presuppose an ontological dualism of human beings and other natural components, and hence cannot recognize the inherent value of nature.
