This study has a purpose mainly to analyze the team interaction change by the duration of time in the Capstone-Design activities according to MBTI Modes. Study objects are four students of Mechanical Engineering at School of Engineering in C University located in Daejeon, and the team interaction change was analyzed through IPA (Interaction Process Analysis) method. From the result, first, ESTP showed the change of increase in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive' and 'task area: question', and the change of decrease by the same time duration of periods in 'task area: solution'. Also, there was no change in 'social-emotional area: negative' because there was no interaction. Second, ESFJ showed the change of decrease in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive' and 'task area: question', and the change of increase by the same time duration of periods in 'task area: solution' and 'social-emotional area: negative'. Third, ISTJ showed the change of decrease in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive', 'task area: question' and 'social-emotional area: negative', and the change of increase by the same time duration of periods in 'task area: solution'. Fourth, ENFP showed the change of decrease by the time duration of initial, mid, late periods in 'social-emotional area: positive', 'task area: solution' and 'social-emotional area: negative', and the change of increase by the same time duration of periods in 'task area: question'.

본 연구는 비콘 기반의 웨어러블 디바이스를 통해 Social Distance로부터 감성 상호작용을 인식하기 위한 기술을 개발하였다. 인식된 상호작용은 Photoplethysmogram(PPG)로부터 추정된 심혈관 동시성과 비교하여 평가되었다. 상호작용은 Social Distance가 일정 시간 이상 유지되었을 경우 인식되었으며, 심혈관 동시성은 PPG로부터 계산된 Beats Per Minute(BPM) 간의 상관분석을 통해 추정되었다. Social Distance로부터 유효한 상호작용을 인식하기 위한 유지시간을 결정하기 위해 상호작용 대상일 때와 아닐 때의 심혈관 동시성에 대해 Mann-Whitney U test를 실시하였다. 15개 집단(집단 당 2명)이 실험에 참여하였으며, 이들은 일상생활에서 비콘 및 PPG 웨어러블 디바이스를 착용하도록 요청받았다. 그 결과, 본 연구에서 인식한 상호작용 대상은 더 높은 심혈관 동시성을 보이는 것으로 나타났으며, 유효 상호작용 시간은 통계적 유의차를 보이는 11초로 결정되었다(p=.045). 결과적으로 실 공간에서의 사회관계망에 대한 실시간 측정과 평가를 할 가능성을 높였다.

The purpose of this study was to examine the effects of goal contents on failure tolerance in engineers (i.e., students and experts in engineering). Based on the goal contents theory, which is a sub-theory of self-determination theory, three intrinsic goals (i.e., self-growth, help, social concern) and two extrinsic goals (i.e., money, fame) were under investigation. A total of 398 participants (118 undergraduate students, 181 graduate students, 99 experts) answered survey questions. In the hierarchical multiple regressions, self-growth goal was entered as the first model, then, to the second model, the other four goals were added. The results showed that social concern goal significantly predicted failure tolerance among all engineer groups. Self-growth goal was closely associated with failure tolerance in undergraduate students and graduate students. Help goal was significant only among graduate students. These results suggest that pursuing intrinsic goals, especially, social concern goal is important to increase failure tolerance. Establishing infrastructure and educational climate for pursuing social concern goal can facilitate the development of personal expertise in engineers as well as the improvement of society.

Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

Recently, there have been fast-growing social network services based on the Internet environment and web technology development, the prevalence of smartphones, etc. Social networks also allow the users to convey the information and news so that they have a great influence on the public opinion formed by social interaction among users as well as the spread of information. On the other hand, these social networks also serve as perfect environments for rampant malware. Malware is rapidly being spread because relationships are formed on trust among the users. In this paper, an effective patch strategy is proposed to deal with malicious worms based on social networks. A graph is formed to analyze the structure of a social network, and subgroups are formed in the graph for the distributed patch strategy. The weighted directions and activities between the nodes are taken into account to select reliable key nodes from the generated subgroups, and the Incremental PageRanking algorithm reflecting dynamic social network features (addition/deletion of users and links) is used for deriving the high influential key nodes. With the patch based on the derived key nodes, the proposed method can prevent worms from spreading over social networks.

This study aimed to investigate the views of STEM college students on the social responsibility of scientists and engineers. A total of 660 students in STEM majors at several Korean universities participated in the study. We assessed social responsibility among college students in STEM majors using the VSRoSE scale, which taps into eight different domains of social responsibility: Concern for human welfare and safety (HUMAN), Concern for environmental sustainability (ENVIR), Consideration of societal risks and consequences (CONSEQ), Consideration of societal risks and consequences (CONSEQ), Consideration of societal needs and demands (NEEDS), Pursuit of the common good (COMGOOD), Civic engagement and services (CIVIC), Communication with the public (COMMU), and Participation in policy decision-making (POLICY). Group differences in social responsibility by gender, majors, and years in school were examined. Mean scores in HUMAN, ENVIR, and CONSEQ were relatively higher than those in NEEDS, COMGOOD, CIVIC, COMMU, and POLICY. Cluster analysis identified five different groups with similar patterns of social responsibility scores. In addition to two groups with overall high and low scores across all eight factors of VSRoSE, three additional groups with different combinations of high and low scores in different factors were identified. The results indicated that students with low social responsibility are not homogeneous and these heterogeneous sub-groups of students will need tailored interventions highlighting different factors of social responsibility that they lack. Pedagogical implications of social responsibility for education were discussed.
