In this paper, we suggest a route plan sharing service for the navigation assistance service which is the second item of 16 items in maritime service portfolios (MSPs) for safety navigation based on interview process. Also, we developed scenarios for effectiveness evaluation of the proposed service, and conducted simulations using full mission ship handling simulator (FMSS) for effectiveness evaluation of proposed services based on the developed scenarios. Through the simulations, we analyzed proximity measures, controllability statistics and subjective evaluations to assess the usefulness of suggested service. If accomplishing the test for new services to apply real ships and vessel traffic (VTS) center, there has possibilities to occur various risks in terms of time/cost problems. Therefore, there is needs for the preliminary effectiveness evaluation processes necessarily when adopts and implements new services. Because we expected the service that is helpful for safety navigation, but the test results are not when conducted a simulation.

The increase in the number of private automobiles has incurred various traffic problems. Globally, studies on MaaS(Mobility as a Service) has already been initiated to mobilize the use of public transportation in reducing private passenger cars in roads. This study aims to analyze the passenger's optimal route considering the transfer between different transportation modes through simulation, and analyze the effect of available route through the connected transportation modes. Sejong Special Self-Governing City was chosen as the study area due to its extensive transportation network. As a result of the analysis, the predominant obtainable route is derived either from using public transportation (i.e. bus and subway) only or by bicycle. However, it is also possible to use the car sharing and public bicycle to reach their final destination efficiently when paths that can be traversed were more scrutinized. When various transportation information and location-based services are introduced in smart phone applications, they can provide very useful information to passengers, and also promote social problems such as traffic congestion and environmental issues in the future.

Objectives: This study aims to investigate the married female immigrants' experience on Korean dietary life adaptation, especially identifying the symbolic meaning and nature of experiences. Methods: This study was conducted with six married female immigrants through an analysis of the qualitative materials which consisted of in-depth interviews, field notes and materials. Data was analyzed using Giorgi's phenomenological research methods. Results: The results were deduced as 116 significant statements, 17 formulated meanings (sub-theme), and 6 theme clusters. Six theme clusters comprised of lack of preliminary knowledge and information, conflict and support in relationships, Korean food culture which is different from homeland, adaptation attitudes of Korean food culture according to situation, sharing of homeland food culture, and practical difficulty and expectative service. The participants started Korean life in the dark about Korea and Korean food culture, so they were subjected to trial and error. The conflict between Korean mother-in-law and foreign daughter-in-law came from lack of consideration of daughter-in-law's cultural background. Some participants were hurt because of misunderstanding and nitpicking. They were learning about cooking method, ingredient, seasoning, table setting and manner. Some participants integrated Korean food culture and their homeland food culture. Some of them assimilated with Korean food culture. One of them maintained homeland food culture. The participants who adapted Korean food culture well could share homeland food amicably. They sometimes didn't apply the services which were offered by the government, because the services did not fit their needs. Some of them didn't know the usage route of the services or information. They had resistance about home teaching and it showed that outreach service was not always effective. Conclusions: This study suggested that it is necessary to develop a practical support plan which covers married female immigrants' real needs and system improvement measures.
