The rapid growth of internet users and faster network speed are driving the new ICT services. ICT Technology has improved our way of thinking and style of life, but it has created security problems such as malware, ransomware, and so on. Therefore, we should research against the increase of malware and the emergence of malicious code. For this, it is necessary to accurately and quickly detect and classify malware family. In this paper, we analyzed and classified visualization technology, which is a preprocessing technology used for deep learning-based malware classification. The first method is to convert each byte into one pixel of the image to produce a grayscale image. The second method is to convert 2bytes of the binary to create a pair of coordinates. The third method is the method using LSH. We proposed improving the technique of using the entire existing malicious code file for visualization, extracting only the areas where important information is expected to exist and then visualizing it. As a result of experimenting in the method we proposed, it shows that selecting and visualizing important information and then classifying it, rather than containing all the information in malicious code, can produce better learning results.

Construction Management is the overall management of the project as construction manager and the owner are united together. Construction manager's role is to conduct the overall or partial construction administration in the 'design, bid, build' process, in the owner's interests with maintaining technical neutrality. Construction manager is becoming one of new professionals in the building process and the contract defines their roles and the range of services, so high level of ethnics are required. This study suggests the legal status of the construction manager and the ethnic standards and the ethnic's characteristics. In conclusion, firstly, the legal characteristics of the administration of construction management are the delegations contract, the responsibility of negligence and the duty of due diligence, abided by the contract that ties between the owner and the construction manger. Secondly, the administerial characteristics of the construction management are the role of mediator, the service of professional technology, accountability to the owner and publicness. Thirdly, due to these characteristics, as a professional, the standard of ethnic assessment for the construction project manager are intention, act and result, so with the relation to that, morality, deontology and consequentialism have been suggested in this study.

In this paper, the educational effects of NETCLASS(network-based collaborative learning system) for EICE(education on information communication ethics) were verified by a non-equivalent control group protest-posttest design. We experimented our system on an experimental group (45 learners) and a comparative group (45 learners) respectively with a defining issues test (DIT). The t-value is 5.108 which shows the difference of the mean value between the experimental group and the comparative group, and their average p-mark shows that the difference is statistically meaningful at p<.001 level. Thus, the experiment using NETCLASS and DIT suggests that the morality of the experimental group is higher than that of the comparative group(t(88)=+5.108, p<.001). This paper suggests very strong possibility that the abilities such as creativity, sociality, morality and emotivity can be improved by utilizing ICT(Information and Communication Technology).

This paper is to critically review the economic reasoning of non-sustainability of welfare state due to its intrinsic incentive problems and to see how the nordic welfare state responds to them. The welfare state as a political design of state to pursue equality has social insurance as its main economic function. It survives market failure of private insurance to contribute to human capital investment and industrial restructuring. The universal tax-financed welfare state, however, has the problem of tragedy of commons such as reduced work incentive and work ethics. But, the existing nordic welfare state overcomes it through employment-focused policy arrangements, maintenance of work ethics and benefits moral, incentive mechanism of wage-compression, public educational investment and its complementation with social security. The Nordic model shows that problems of incentive and moral are not about those of theory and reasoning, but about their reality which policies and institutions could respond to.

This paper is the UX-based technology strategy research which is a solution to how conversational AI can be ethically evolved in the Metaverse environment. Since conversational AI influences people's on-offline decision-making factors through interaction with people, the Metaverse AI ethics must be reflected. In the machine learning process of conversational AI, cultural codes along with user's personal experience data must be included and considered to reduce the error value of user experience. Through this, the super-personalized Metaverse service can evolve ethically with social values. With above hypothesis as a result of the study, a conceptual model of a forward-looking perspective was developed and proposed by adding user experience data to the machine learning (ML) process for context-based interactive AI in the Metaverse service environment.

Ahead of the introduction of artificial intelligence education into the revised curriculum in 2022, various class cases based on artificial intelligence should be developed. In this study, we designed an artificial intelligence education program based on explainable artificial intelligence using design-based research. Artificial intelligence, which covers three areas of basic, utilization, and ethics of artificial intelligence and can be easily connected to real-life cases, is set as a key topic. In general design-based studies, more than three repetitive processes are performed, but the results of this study are based on the results of the primary design, application, and evaluation. We plan to design a program on artificial intelligence that is more complete based on the third modification and supplementation by applying it to the school later. This research will help the development of artificial intelligence education introduced at school.
