The appearance of mass media and a versatile medium of videos can serve the convenience and instructive information for children; on the other hand, it could abet them in implicit image consumption. Now is the time for kids' to be in need of thinking power which enables them to make a choice, applications andcriticism of information within such visual cultures. In spite of these social changes, the realities are that our curriculum still doesn't meet a learner's demand properly. This research, (...) in this context, is aimed at looking out on the currently implemented art appreciation learning process in a critical fashion, and also aimed at suggesting a plan for visual culture learning by applying the philosophy program for kids as a new alternative. The purpose of such education is toenhance the capability to solve a variety of problems they are facing in the course of daily life by reflecting their matter of concern in a curriculum. What we have to pay attention to in visual culture learning is 'visual literacy.' Such an interpretative faculty of a critical reading of images is a must especially when kids should make a judgment of value hidden in images in their daily events, make an analysis of an ideological message and make an information-oriented decision. Therefore, learners have to enrich their higher-order thinking power as well as critical thinking faculty in modern society. If there is no objection to these social surroundings, it is quite natural that philosophy education, which forms a base of a higher-order thinking for children should be handled significantly at school.

Negation is frequently found in every language, and many logicians or linguists have been carrying out research on it. Their investigations are, however, mostly confined to the languages of Europe. Although some of them pay attention to non-European languages, we can hardly find research on negation in Korean. In this paper, we carry out contra-linguistic analysis of four aspects of negation in Korean and English. First, we compare the expressions of negative elements in Korean and English sentences. Second, we contrast (...) the types of negation in Korean with those of English. Third, we draw a distinction between Korean and English in what decides the scope of negation. Finally, we contrast the answers to questions which contain negative elements. (shrink)

Cancer chemotherapy has been the most common cancer treatment. However, it has side effects that kill both tumor cells and immune cells, which can ravage the patient’s immune system. Chemotherapy should be administered depending on the patient’s immunity as well as the level of cancer cells. Thus, we need to design an efficient treatment protocol. In this work, we study a feedback control problem of tumor-immune system to design an optimal chemotherapy strategy. For this, we first propose a mathematical model (...) of tumor-immune interactions and conduct stability analysis of two equilibria. Next, the feedback control is found by solving the Hamilton–Jacobi–Bellman equation. Here, we use an upwind finite-difference method for a numerical approximate solution of the HJB equation. Numerical simulations show that the feedback control can help determine the treatment protocol of chemotherapy for tumor and immune cells depending on the side effects. (shrink)

Pathological gaming among adolescents has been reported to hamper the achievement of a balanced life and to threaten the development of social competencies. Despite the increasing social concerns on the adolescent users, however, the mechanism of gaming behavior of adolescents has not been sufficiently examined. This study explored the mechanism of pathological gaming among adolescents from 3-year longitudinal data of 778 Korean adolescent gamers, by analyzing the effects of negative affects on the degree of pathological gaming through the mediation variables (...) based on the stimulus-organism-response framework. Latent class analysis was used to uncover potential risk groups, and through partial least squares-structural equation modeling analysis, the mediation pathways to pathological gaming were compared between the risk group and the non-risk group. The results highlighted the key role of academic stress on the degree of pathological gaming. In the entire group, academic stress primarily increased pathological gaming through self-control. The mediation path of self-control was the most influential result in the risk group. Aggression was the key mediator between loneliness and pathological gaming in the non-risk group. The theoretical and practical implications of the results were discussed. (shrink)

The main purpose of this study was to validate a scale to examine the moral sensitivity of Korean nurses. A pre-existing scale, the Moral Sensitivity Questionnaire (MSQ), developed by Lützén, was used after deletion of three items. The reliability and validity of the scale were examined by using Cronbach’s alpha and factor analysis, respectively. According to the results, reliability of the scale was adequate but its construct validity was not fully supported. Through discussion on evidence of validity, five subconstructs emerged. (...) In particular, unlike the factor structure of the MSQ, two subconstructs, patient-oriented care and professional responsibility, were newly extracted. It was assumed that the other three MSQ subconstructs, conflict, meaning and benevolence (expressed as nurses being ethically good), would not be sensitive to cultural background. Given these findings, interpretations about the meaning of moral sensitivity of Korean nurses are discussed. (shrink)
