Cyclic voltammetry was used for elucidating the electrochemical behavior of Ru-cupferron complex in 1 mM phosphate buffer. The optimal conditions of ruthenium were found to be 1 mM phosphate buffer solution (pH 6.0) containing 0.1 mM cupferron, scan rate of 100 mV/s. By using the plot on the reduction peak currents of linear scan voltammograms vs. ruthenium concentration, the detection limit ($3{\sigma}$) was $1.2{\times}10^{-7}M$.

인간의 감성은 인간의 생활에서 논리적 사고와 의사결정, 감정의 발생, 행동 등 모든 부분에서 관련을 가진다. 이런 인간의 감성을 정성 정량적으로 측정 평가하여 제품이나 환경 설계에 응용한다면 더욱 편리하고 안락하며 안전하게 하는 등 인간의 삶을 쾌적하게 할 수 있다. 그래서 인간의 감성을 파악하기 위한 연구가 여러 방향으로 추진되고 있으나, 인간의 감성이 상당히 주관적이고 애매하며 불확실하기 때문에 이를 객관적이고 합리적으로 파악하는데 많은 어려움이 있다. 이 논문에서는 Chroma 법을 이용하여 개별적 인간 감성 자료를 얻었고, 이렇게 수집된 감성 자료를 평가하기 위한 방법으로 클러스터 분석법을 이용한다. 그리고 개별적 인간 감성 자료에 대한 사례 연구를 통해 자료 평가의 타당성을 검증하고자 한다.

User-centered design aims to develop device naturally without the interference of user' s conscious and unconscious behavior. Accordingly, designers need to understand their user's requirements, observe user behavior and interaction in the real environment. However, existing observations suggested a vast range of analysis system and observation techniques which are often ambiguous to the designers. Therefore, this research is aimed to propose an observation system for collecting data from user's behavior. In order to do so, we define the components and behavior level within the context of driving.

The purpose of this study is to examine a preservice elementary mathematics teacher's beliefs and stated-actions in which she planned and implemented mathematical activities in a field experience within a mathematics methods course. Results show that the preservice teacher seemed to be dealing with conflicts and trying to resolve them in order to make sense to herself. Results also suggest that the preservice teacher's beliefs about how children learn seem to get confirmed through the field experiences so that she was able to articulate, which influence her experience of focusing on an individual child. This, in turn, induces her to elaborate her beliefs. These processes would explain her beliefs and actions as a sensible system.

The aim of this study is to analyze the effects of DVR(Driving Video Recorder) operation on decreasing the number of traffic accidents, the cost of traffic accident claim, and the behavioral change in drivers' driving. The data for this research are obtained from taxi drivers in Busan. For this, Structural Equation Model and two-way ANOVA are employed for empirical analysis. Overall results of this study show that the number of traffic accidents of 4 taxi corporations in Busan has decreased by average 32.7 percent after using DVRs. In addition, as to the cost of taxi accident claims, it is expected that the DVR operation has a considerable effect on economic benefits of taxi corporations. Moreover, this study could make clear the difference in behaviors between DVR users and non-users, and discriminate the positive and negative impacts of the DVR operation on the drivers' driving behavior. The study quantitatively examined the indirect impact of 'attitude', 'subject norm' and 'behavioral control' factors on planned 'behavior', and the direct impact of 'behavioral control' factor on the planned 'behavior'. This study suggests that they should add the video recoding function of DVRs when operation recorder(blackbox for the car) is obligatorily set up on cars for business by traffic security law.

This study presented the analysis results and implications by identifying the structural relationship between the image of food tourism products, the long-term orientation of attachment, and the behavioral intention. The convenience sampling method of the non-probability sampling method was used, and the survey was conducted non-face-to-face due to COVID-19. This study was conducted for customers who live in Jeollabuk-do and Jeollanam-do and have experienced local traditional food. As for the survey method, the main researcher's acquaintances and related experts were consulted and utilized to select the survey subjects, and the survey was conducted by sending/returning them by mail or e-mail. Statistical processing was analyzed using SPSS 25.0 and AMOS 25.0 statistical packages. As a result of the verification, the relationship between the image and attachment of food tourism, the relationship between the long-term orientation in the attachment of traditional food, and the behavioral intention in the attachment of traditional food are significant. A significant positive (+) relationship was formed in the relationship of hypothesis setting according to the research purpose of the relationship.

Summary：This study was designed to examine the effect of mother's depressive mood and parenting related attitude on parenting behavior, focusing on the cases having an ADHD child. Method：A total of 82 parents, 31 parents having children with ADHD and 51 normal, were involved in this study. The children of ADHD and normal group were 6-11 years old. ADHD group were diagnosed as attention-deficit hyperactivity disorder by psychiatric doctor and psychological evaluations using DSMIV criteria and the normal group were excluded by using Diagnostic Rating Scale-Parent, Teacher Form. The mothers of both group completed a series of questionnaire about mother's depressive mood and parenting-related attitude. To investigate the relationships between each variables, Student's t-test, correlation, stepwise regression, and hierarchical regression analysis were performed. Result：In correlation analysis, Mothers with an ADHD child were likely to report more coercive parenting behavior, more negative parenting-related attitudes, and depressive mood than normal group. In regression analysis, mother's parenting stress, dysfunctional thoughts, parenting competence, and depressive mood predicted coercive parenting behavior significantly, total explaining 50% of its variance, and especially depressive mood explained 29% of their coercive parenting behavior. These Results indicated that mother's depressive mood accounted for a substantial portion of coercive parenting behavior. Conclusion：These findings suggested that it is significantly important to reduce Mother's depressive mood through dealing with parenting sense of competence and dysfunctional thoughts, so, both parent education program and cognitive-behavioral therapeutic approach are needed to change parent's coercive parenting behavior. Finally, limitation of the present study and suggestions were discussed for further studies.

This study was conducted to compare and examine the knowledge, affectivity and behavior of students between before and after Internet ethics education depending on education method. The class for A group was being taught by tutor-oriented teaching method based on explaining and the class for B group was characterized by student-oriented studying based on participation of students. Upon comparing the changes of the knowledge, affectivity and behavior after Internet ethics education, the tutor-oriented teaching method was more effective for knowledge in Internet ethics education and the student-oriented studying based on participation of students was more effective to change the student's affectivity. In the behavior, both A group and B group had a tendency to be changed positively after education, but there was no statistically significant difference. In order to produce actual results on Internet ethics education as integrated morality education, it is important for students to join and take a leading role in the class and for tutor to teach students supplementarily what they need to know essentially.
