This study applied the Theory of Reasoned Action by Fishbein & Ajzen(1975) as the grounded theory and adopt sanctions of the General Deterrent Theory and protection motivation of the Protection Motivation Theory as the antecedents to discuss the theoretical factors and the cases of application in the field of information security. Then, it adopted subjective norm, a variable of the Theory of Reasoned Action, as a parameter to analyze the causality of sanctions, perceived vulnerability, response cost, and self-efficacy with the intention to follow the information security policies. As a result, all of the antecedents except for sanctions had causality with the intention and subjective norm proved its mediating effect as a parameter between the antecedents and the intention.

This study examined the relationship between internet ethics, self-control, nursing professionalism, and patient privacy awareness among nursing students with clinical practice experience, and attempted to provide basic data for the development of patient privacy awareness improvement programs reflecting the flow of information age. The data collection period was from November 20 to December 15, 2023. The questionnaires of 142 nursing students who agreed to participate in this study and were enrolled in D and C universities in Daejeon Metropolitan City and Cheongju City were analyzed. The results showed that nursing professionalism and self-control were the influential factors on nursing students' perception of patient privacy. The explanatory power of these variables was 24%. In conclusion, in order to improve the patient privacy awareness of nursing students, it is necessary to explore ways to promote the ethical awareness of internets and develop educational programs to increase nursing professionalism.

The purpose of this study was to investigate the effects of Self-Efficacy and Job Stress on Quality of Service. Data were collected through self reported structured questionnaire from Care givers using convenient sampling methods from May 1 to August 30, 2019. The data were analyzed with SPSS/WIN 25.0 using independent t-test, one way ANOVA, Pearson's correlational coefficient and multiple regression. These factors together explained 42.0% of the Quality of service in Care givers(F=13.86, p=<.001). Factor influence the Quality of Service was Self-Efficacy(β=0.56, p=<.001). The findings of this study indicate that education programs should be developed to improve the self-efficiency of caregivers and that further studies should be conducted on their effects.

Recently, the application of paint protection films (PPFs) for automobiles having a self-recovery coating layer has been grown up. In this study, we report the evaluation results on the basic physical properties of a poly(vinyl chloride)- based PPF containing poly(urea-urethane) hybrid self-recovery coating layer. Depending on the main chemical composition and the thickness of poly(urea-urethane)-based coating layer for PPF, the self-recovery performance by an optical microscope and the stain resistance through color difference value are measured. To improve the surface properties and show its easy-cleaning effect against the polluted things, silicone-modified polyacrylate is introduced to the self-recovery coating composition. The contact angle of water on the coated surface is confirmed to show its hydrophobic surface. Finally, accelerated weathering test of paint protection film with poly(urea-urethane) hybrid coating layer is performed to check the possibility of discoloration and deformation due to long-term exposure on harsh condition.

Recently, Gallant, Lambert arid Vanstone introduced a method for speeding up the scalar multiplication on a family of elliptic curves over prime fields that have efficiently-computable endomorphisms. It really depends on decomposing an integral scalar in terms of an integer eigenvalue of the characteristic polynomial of such an endomorphism. In this paper, by using an element in the endomorphism ring of such an elliptic curve, we present an alternate method for decomposing a scalar. The proposed algorithm is more efficient than that of Gallant\`s and an upper bound on the lengths of the components is explicitly given.

As the demand for elderly care service has been on rise due to the increasing of the aging population, the role of visiting caregivers becomes increasingly important. In this context, this study aims to examine whether there are moderating effects of social support and self-efficacy on the relationship between resilience of visiting caregivers and their burnouts. The hierarchical regression analysis was used for statistical analysis. The findings from the study are as follow. First, resilience has a negative effect on burnout. As the resilience increases, the burnout decreases. Second, social support has moderating effects on the relationship between a resilience sub-variable(positivity) and burnout. Third, self-efficacy has a moderating effect on the relationship between a resilience sub-variable(self-regulation) and burnout. The findings of the study suggest that nursing facilities pay attention to psychological characteristics of visiting caregivers as well as their job characteristics in designing burnout prevention programs for them.

전력계통에서 전류를 측정하는 변류기는 주요 전력 설비와 연계되어 보호 및 감시에 있어 중요한 역할을 수행한다. 그러나 기존방식의 전류 변성기는 자기포화에 의한 파형 왜곡과 써지나 잡음 등의 전기적 장치가 갖는 구조적 문제점을 가지고 있다. 이러한 문제점을 개선하기 위한 방법으로 전류에 의해 형성된 자계에 의해 광신호의 편광(polarization) 회전을 발생시키는 Faraday 효과를 가지는 광센서를 이용하여 보호계전 분야에 적용 가능한 전류계측기술을 개발하였다. 본 논문에서는 기존 전류변성기의 계통 보호에서 발생하는 문제점을 PSCAD/EMTDC 시스템을 이용하여 시뮬레이션 하였으며, 아울러 동일 조건에서 광 CT의 동작 특성을 산출하여 기존 전류변성기와 비교 분석하였다. 분석 결과들로부터 광 CT는 기존 전류변성기가 자기포화되는 상황에서도 정확한 1차 전류의 측정이 가능함을 보였다.

생체 면역시스템은 바이러스나 병원균 등의 외부 침입자로부터 자신을 보호한다. 본 논문에서는 이러한 기능을 컴퓨터 면역시스템에 적용하기 위하여 생체 면역시스템의 기본 요소인 T세포를 모델링 하였다. 모델링한 T세포는 MHC 인식부와 항원 인식부를 가지고 있으며, 매칭을 통하여 컴퓨터내의 랜덤 파일로부터 자기 파일과 비자기 파일을 구분할 수 있다. 모델링한 T세포의 유효성을 보이기 위해서 컴퓨터 바이러스의 문제에 적용하여 자기-비자기 구분이 가능함을 보인다.
