More than half of all incidents in large complex technological systems, particularly in nuclear power or aviation industries, were attributable in some way to human erroneous actions. These incidents were largely due to the human engineering deficiencies of man-machine interface (MMI). In nuclear industry, advanced computer-based MMI designs are emerging as part of new reactor designs. The impact of advanced MMI technology on the operator performance, and as a result, on plant safety should be thoroughly evaluated before such technology is actually adopted in nuclear power plants. This paper discusses the applicability of human reliability analysis (HRA) to support the design review process. Both the first-generation and the second-generation HRA methods are considered focusing on a couple of promising HRA methods, i.e., ATHEANA and CREAM, with the potential to assist the design review process.

As various mobile robots and manipulator robots have been commercialized, robots that can be used by individuals in their daily life have begun to appear. With the development of robots that support daily life, the interaction between robots and humans is becoming more important. Manipulator robots that support daily life must perform tasks such as pressing buttons or picking up objects safely. In many cases, this requires expensive multi-axis force/torque sensors to measure the interaction. In this study, we introduce a low-cost two-axis pressure sensor that can be applied to manipulators for education or research. The proposed system used three force sensitive resistor (FSR) sensors and the structure was fabricated by 3D printing. An experimental device using a load cell was constructed to measure the biaxial pressure. The manufactured prototype was able to distinguish the +-x-axis and the +-y-axis pressures.

The Korea Planning Support Systems (KOPSS) represent Korean style national policy and planning support systems using the GIS-based spatial analysis methods. The KOPSS refers to a kind of the spatial decision support systems (SDSS) or the planning support systems (PSS) for stakeholders' spatial decision-making. The KOPSS uses the existing individual databases obtained from the Architecture Information Systems (AIS) and Land Management Information Systems (LMIS) that have been constructed by information projects since the mid 1990s. The purpose of this paper is to suggest the development strategies and establish the theoretical frameworks of the KOPSS by considering the comprehensive basic composites of the GIS-based SDSS or PSS. For this, it deals with the basic concepts, the development strategies, the base environment strategies, and the promotion strategies of the KOPSS.

The Korean government's support towards the establishment of leading research hubs at universities began with the initiation of the Science/ Engineering Research Center in 1990. Such efforts to provide support to research organizations have continued for some twenty years in various forms, which implies that building research hubs was critical in acquiring global leadership in research. However, the effect of such research hub nurturing policies has never been properly evaluated, apart from an assessment of their validity. Therefore, this paper analyzes how major programs to form research groups by providing assistance to joint research by researchers at universities are operated, and the characteristics of such programs through comparative analysis with other programs. There are two major focal points in the analysis: the first is the evaluation of the level of differentiation between Research Organization Support Programs (ROP) and other R&D Programs from an efficiency perspective, and the second is an examination of the extent of systematization of research organizations that exist at universities and impact of Research Organization Support Programs on the activities of participating professors from an effectiveness perspective. The result showed that the ROP were no longer only relevant for the formation and maintenance of research groups. Other R&D Programs are growing increasingly larger in scale and conducted over longer periods of time. Thus, the ROP can no longer be differentiated from other programs in research period and size of funding. An analysis on the effect of ROP demonstrated that all activities by participating professors in organizations that were the beneficiaries of group research assistance were more active compared to their counterparts in organizations that received other research support, but there was little difference in the elements of systematization. This implies that the joint research conducted at universities is not systematized and that it is still research based on individual themes but conducted jointly. In addition, it also means that the ROP is failing to effectively lead the systematization of research. In other words, today, university research organizations are not operated as independent, long-term bodies, but are more relevant as a combination of research units of individual professors.

Father participation in child rearing is gaining its importance in the field of child development. Previous literature consistently suggests the importance of parental efficacy and educational support on children's school life. However, studies which that focus exclusively on the role of the father's role are highly limited. Based on previous literature, we hypothesized that parental efficacy would directly and indirectly affect children's school life via parental educational support at home. We aimed to expand on the previous literature by exploring the relations within fathers. Participants were 662 fathers whose children attended elementary, middle, and high school. We measured parental efficacy, educational support at home, and their children's school life were measured. Descriptive statistics were first conducted to investigate the general features of participants as well as the correlations between study variables. The research model was analyzed using structural equation modeling in AMOS 20.0. Results proved the direct effect of father's parental efficacy on father's educational support at home as well as children's school life. Fathers' educational support at home mediated the effect of parental efficacy on children's school life. Our results suggests that fathers who perceive themselves as efficient parents provides a higher level of educational support at home for their children; consequently, children of those fathers in turn adjust better in school and achieve higher grades. Also, the father's parental efficacy also indirectly exerts positive effects on children's school life via heightened educational support at home. An importance of paternal participation and support in child rearing and education was highly suggested. Relevant policy issues regarding paternal educational support were discussed.

The purpose of this study was to analyze the effect of spousal attachment on social support the husband provides for his wife, investigate the relationships between spousal attachment and the social support the husband received from the wife, and the view the relationship between the social support provided for the wife and the social support received from the wife during early adulthood. A survey was conducted for this study. The hypotheses were based on adult attachment theory. The results are as fellows: Secure attachment with a spouse had a significant positive effect on motivational support and esteem support provided for the wife. Anxious-avoidant attachment with a spouse had a significant negative effect on instrumental support, social companionship, motivational support, esteem support and informational support provided for the wife. Anxious-ambivalent attachment with a spouse negatively affected instrumental support, social companionship, motivational support, esteem support and informational support provided for the wife. Secure attachment with a spouse was positively related to instrumental support, social companionship, motivational support, esteem support and informational support received from the wife. Anxious-avoidant attachment with a spouse was negatively related to instrumental support, social companionship, motivational support, esteem support and informational support received from the wife. Anxious-ambivalent attachment with a spouse was negatively related to esteem support received from the wife. The results were discussed as they relate to the importance of spousal attachment for a healthy family.

Recently, human action recognition have been developed for various broadcasting and video process. Since a video can consist of various scenes, keypoint approaches have been more attracted than template based methods for real application. Keypoint approahces tried to find regions having motion in video, and made 3-dimensional patches. Then, descriptors using histograms were computed from the patches, and a classifier based on machine learning method was applied to detect actions in video. However, a single classifier was difficult to handle various human actions. In order to improve this problem, approaches using multi classifiers were used to detect and to recognize objects. Thus, we propose a new human action recognition using decision-level fusion with support vector machine and sparse representation. The proposed method extracted descriptors based on keypoint approach from a video, and acquired results from each classifier for human action recognition. Then, we applied weights which were acquired by training stage to fuse each results from two classifiers. The experiment results in this paper show better result than a previous fusion method.
