Purpose: In the Korean railway infrastructure process, contractors and operators are involved at a later stage, which results in significant inefficiency. This study examines the benefits of early stakeholder involvement in Korean railway infrastructure projects and provides practical guidelines. Design, data and methodology: Literatures and foreign cases are analyzed. Building on the new product development model, we derive propositions explaining the relationship between early stakeholder involvement and the performance of Korean railway infrastructure project. Results: Major propositions include that early involvement of contractor has a positive effect on the project performance by shortening the infrastructure construction period and that early involvement of railway operator has a positive effect on the project performance by improving the effectiveness of railway infrastructure. Four requirements for the success of early stakeholder involvement are addressed. Conclusions: This study suggests that early stakeholder involvement shortens the construction period and improves railway infrastructure effectiveness. Academic contribution is to present the framework on railway infrastructure projects as holistic interactions among stakeholders. Practical contribution is to provide railway policy makers and other business practitioners with policy guidelines to improve railway infrastructure project process and to recommend an open access to relevant data.

This study will examine the social issues and consumer awareness of sharing parking through the method text mining. In this experiment, the topic by keyword was extracted and analyzed using TFIDF (Term frequency inverse document frequency) and LDA (Latent dirichlet allocation) technique. As a result of categorization by topic, citizens' complaints such as local government agreements, parking space negotiations, parking culture improvement, citizen participation, etc., played an important role in implementing shared parking services. The contribution of this study highly differentiated from previous studies that conducted exploratory studies using corporate and regional cases, and can be said to have a high academic contribution. In addition, based on the results obtained by utilizing the LDA analysis in this study, there is a practical contribution that it can be applied or utilized in establishing a sharing economy policy for revitalizing the local economy.

The competence of SME's technological innovation is deemed as one of the crucial factors in national and regional economies. Yet, as seen in previous studies, there is a dearth of studies on this subject, and policy and academic circles had been inclined to relatively underestimate the contribution of the SMEs to economies and industries (such as, job creation and GDP contribution). Generally, there is a bias that the innovative activity of the large-sized firm is likely to perform better than that of the small-sized company. According to several case studies, however, SME possesses a more appropriate form for innovative activities, and significantly contributes to creating advanced industrial agglomeration. Hence, this study analyses the contribution of the SME innovation to the national and regional economy along with analysing the extant literature. In doing so, we can reason out theoretical and policy implications.

This paper empirically analyzes the relationship among the perception variables on the EU and Korea-EU FTA. According to the empirical results, first of all, while Korean university students understand the importance of EU less than those in the US or Japan, they understand the importance of EU more those in China. The understanding and importance of Korea-EU FTA are measured somewhat lower than Korea-US FTA. Second, Contingency Tables show that there exist some associated relationships between the sex and the understanding of the regions, and Korean university students have some differences in understanding the importance of the EU by sex. ANOVA shows that the more they understand the EU and recognize the importance of Korea-EU FTA, they recognize that the Korea-EU FTA's contribution to Korean economy and EU's & EURO's contribution to world economy will be bigger. Third, the cannonical correlation test shows that by the academic grade and sex there are some significant differences in understanding the importance of the EU and main countries and regions. The discriminant analysis shows that there exist some differences in recognizing the contribution of Korea-EU FTA's to Korean economy.

Purpose: The purpose of this study was to identify the experiences of Team-Spirit training in new nurses. Method: Data was collected through open-ended and self-reported questionnaires which were received from 47 new nurses who had finished team-spirit training for 2 days. The content analysis method was used to derive the core-category, categories and concepts of Team-Spirit training for new nurses. Result: The care category identified in new nurses trained in Team-Spirit was upgrade myself and our team. The following 4 categories also emerged; companion, interdependency, importance of community, and future growth of myself and our community. The derived 12 subcategories were intimacy, importance of companions, binding, partaking in difficulties, empowerment, observing rules, cooperation, consensus, self-pledge as a subordinator, motivating vision formation, developing professionalism, contribution and devotion. The 34 concepts were derived from the new nurses' statements. Conclusion: These results imply that Team-Spirit Training for nurses could contribute to companionship, interdependency, importance of community, and future growth of oneself and the hospital team.

Purpose: To identify the health condition, home care support, support requirement of poor and elderly people living alone. Method: Data was collected through self-administered questionnaires and analyzed by descriptive statistics, t-test, ANOVA and correlation. Survey involved 269 conveniently selected who have a social support in H city. Result: Perceived health condition of subjects was bad to moderate (mean score: 2.22). There were significant home care support differences according to gender, religion, education level and dwelling pattern. Support requirement was influences only by the dwelling pattern. Perceived health condition showed a positive correlation with home care support of friends and neighbors, and a negative correlation with support requirement (medical, material, economic emotional support). Conclusion: These findings are expected to make a positive contribution to create an ideal intervention for public visiting nurses and social workers to improve the quality of life in poor and elderly people who live alone.

Whipping/springing research started in the 50'ies. In the 60'ies inland water vessels design rules became stricter due to whipping/springing. The research during the 70-90'ies may be regarded as academic. In 2000 a large ore carrier was strengthened due to severe cracking from North Atlantic operation, and whipping/springing contributed to half of the fatigue damage. Measurement campaigns on blunt and slender vessels were initiated. A few blunt ships were designed to account for whipping/springing. Based on the measurements, the focus shifted from fatigue to extreme loading. In 2005 model tests of a 4,400 TEU container vessel included extreme whipping scenarios. In 2007 the 4400 TEU vessel MSC Napoli broke in two under similar conditions. In 2009 model tests of an 8,600 TEU container vessel container vessel included extreme whipping scenarios. In 2013 the 8,100 TEU vessel MOL COMFORT broke in two under similar conditions. Several classification societies have published voluntary guidelines, which have been used to include whipping/springing in the design of several container vessels. This paper covers results from model tests and full scale measurements used as background for the DNV Legacy guideline. Uncertainties are discussed and recommendations are given in order to obtain useful data. Whipping/springing is no longer academic.
