Purpose: This study aimed to have an in-depth understanding of the structure and essence of the living experiences of unmarried mothers institutionalized after childbirth through phenomenological research. Methods: The data were collected through in-depth interview with 9 unmarried mothers from October 1, 2016 to February 2017 and this is qualitative research using Colazzi's phenomenological research method. Results: The living experiences of unmarried mothers institutionalized after childbirth had 15 themes in 4 theme clusters: 'childbirth and parenting,' 'living in women's refuge,' 'becoming independent as proud mother,' and 'disentangled thread.' Conclusion: After childbirth, unmarried mothers experienced psychological pressure from the need to cope with lonely and wearing reality by themselves but struggled to overcome the reality together with their child. Unmarried mothers hoped to live the life they chose proudly and happily together with their child. It is therefore necessary to give residential and environmental support to unmarried mothers in pursuit of their stable living and to change the awareness in the whole society with the aim of removing negative social attitude and discrimination, accepting differences, and living together.

The development and operation of the MASS (Maritime Autonomous Surface Ship) is being actively discussed for more efficient and safer maritime transportation solutions. The autonomous navigation technology has positive aspects such as the prevention of marine accidents, improvement of fuel efficiency of ships and cost reduction, and negative aspects such as job loss, task change, and security problems. It is expected that there will be new human element issues such as the situation awareness of remote operators, because the shore-based control will be conducted when fully autonomous ships are in operation. In this paper, we consider major human element issues that should be factored in the development and operation of MASS, and suggest a method of HRA (Human Reliability Analysis) for P IFs (Performance Influencing Factors) of the remote operators that are expected according to the shore-based control.

In the era of the 4^th industrial revolution and convergence, various discussions and studies have been conducted to develop future social talents, and through this, the need for creative convergence talents is increasing. In line with the change to a software-oriented society, countries around the world are trying to strengthen SW education, but high school students' awareness of the necessity of information subject and SW education that is the center of convergence is insufficient. Therefore, opportunities for convergence of the information subject and various fields should be provided. In this study, information education was converged to the science exploration experiment subject to construct an educational program that can develop creative convergence, and a convergence class using physical computing were applied to high school students for 9 hours. As a result of the experiment, the recognition of SW education of the experimental group was improved, and it was confirmed that the learner's convergence literacy of the experimental group was statistically different from that of the control group that conducted the general science experiment class.

This study deals with current use of e-books through a survey of e-book audiences and a diagnosis of the development perspective of e-book audiences. In addition, we present some effective methods to promote e-books in the future. The study shows that e-book users have increased. However, e-books are not well-known to the audience. Mainly, audiences use free web sites; consequently, the use of e-books is not well-promoted. Whether people have used e-books is statistically significant in the pattern of their use and e-book audiences prospect that the future of e-books is brighter than paper books. However, people who have used e-books prospect the brighter future for e-books than people who have never used them. Therefore, we should reconsider the accessibility to e-books, promote publicity, research the reliability of the contents, reduce the price, develop various contents, change layout for better readability, and develop the screen for the less eye fatigue to promote e-books.

The displacement of business tenants is of growing concern in urban redevelopment. This research focuses on why business tenants have not collectively taken action against urban redevelopment and explores how their rights can be improved. It met the research aim through a case study on one urban redevelopment area in Yongsan. Although urban redevelopment plans create many problems for business tenants, there is no effective mechanism in place to enable them to get involved in the decision-making procedures of urban planning. They are collectively and individually powerless in urban politics, so they do not have enough opportunities to change the Korean urban redevelopment system. The findings from this research suggest that many tenants have been apathetic to anti-gentrification movements due to their powerlessness in the urban redevelopment domain. In order to overcome structural injustice, it is important to improve business tenants' awareness of 'the right to the city' and enforce strong legislation to safeguard tenants.

Objective: The purposes of this study are to understand the characteristics of the participants in a community walking campaign and to analyze the factors related to their participation based on the Transtheoretical Model (TTM). Methods: The study composed of the description of participant characteristics and comparison of them with non-participant characteristics in a walking campaign in K province. The data were collected through a survey of 2,590 participants and 258 non-participants from the same community. The survey instrument included questions about stages of walking and exercise, knowledge and attitude toward walking, and environmental condition for walking. Results: A majority of the walking campaign participants were in the action(24.8%) and maintenance(43.6%) stages of walking and exercise behavior. The non-participant group was split between maintenance(51.6%) and precontemplation (30.6%) stages. Among the participants, effective campaign promotion channels differed by age group while motivation for participation and participation patterns were associated with both age and gender. Favorable physical environment was a significant factor of participating in walking campaign(OR=1.396, CI=1.149-1.696). Although the campaign participants scored higher than the non-participants in most attitude toward walking questions, differences in knowledge scores between two groups were less significant. Conclusion: In conclusion, further social marketing to increase the awareness and to increase the concern of population in the community is needed based on the survey result. Transtheoretical model seems appropriate to apply to the evaluation and the planning the program of the behavior change in the community. Also, more organized and sustainable support in need to maintain the good habit of walking for the participants in walking campaign.

MANET(Mobile Ad-hoc Network) has been proposed as a infrastructure-less network using distributed algorithm for remote environment monitoring and control. The mobility of MANET would make the topology change frequently compared with a static network and a node is resource-constrained. Hence, to improve the routing protocol in MANET, energy efficient routing protocol is required as well as considering the mobility would be needed. In this paper, we extend RODMRP(Resilient Ontology-based Dynamic Multicast Routing Protocol) structure by a modifying the level of cluster. We call this network protocol CACH-RODMRP. Our contribution consists estimating the optimal level of clustering depth with considering node position and reducing the network residual energy. The simulation results of proposal algorithm show that the energy is significantly reduced compared with the previous clustering based routing algorithm for the MANET.

Background: Communication training in nursing college students is an integral part of the development of their competency in dealing with patients. However, the traditional lecture style of training delivery may not be desirably effective. Purpose: This study investigated the effects of a communication training program utilizing a small group dynamic on the communication competency and human relationships in nursing college students. Methods: One hundred twenty six freshmen in a university in Seoul participated in this study. The instruments of communication competency (Primary Communication Inventory) and human relationships (Relationship Change Scale) were used at the beginning and conclusion of the training period. Eighty-three students from two nursing classes were assigned to the experimental groups and 43 students from other classes were assigned to the control groups. Each of the 11 small groups was composed of 7 or 8 students. The weekly program that ran during the 2007 fall semester from October 1st to December 11th consisted of effective communication strategies including therapeutic communication skills, Johari's window, empathy, active listening, and transactional analysis. Results: The experimental group of students reported significantly greater improvement in communication competencies, specific nonverbal competencies, and human relationships compared with the control group. Specifically, the experimental students demonstrated greater improvement in nonverbal communication competencies and satisfaction, communication, and awareness of human relationships. Conclusions: Small group based communication training can be an effective alternative method of communication education for college nursing students.
