Recently development trends in information technology expand the activity boundaries for human living beyond coastal zones. These rapid changes of paradigm are stimulating scientists and strategists to be encouraged in making adequate model for marine geographic information system (MGIS) and their applications. Coastal zones are places which are affected by many factors, such as water quality, tide, wave, atmosphere, population, industry, etc. Therefore information related to the coast has to be integrated and analyzed for managing it efficiently. GIS-based Ocean Informatics is suited for those purposes and used in the study for establishing and managing coastal geographic and environmental information system. This paper reviews the properties of ocean and coastal spaces, then defines some MGIS related terminologies for clarifying the scope of MGIS boundaries. In this study, coastal geographic information is established by digital geographic information and digital terrain information. Digital coast chart having information on digital chart and map can merge and analyze various coastal information and can be a useful tool for the coastal integrated management.

The objective of this study is to develop education programs for cultivating smart aquaculture experts through a education demand survey of industries, high school students, university (graduate) students and field workers. The industry demand analysis was conducted as an in-depth interview on representives from seven companies. Education demand surveys were conducted on 96 students and field workers in the Jeonnam region. Results on the demand survey were analyzed using frequency analysis and cross-analysis. The company representatives responded that they want to participated in internship and retraining programs to proactively secure manpowers with convergence capabilities about smart aquaculture. Seven companies preferred manpowers with basic competencies on ICT (Information and Communications Technologies) or aquaculture. The most respondents in the demand survey want to participate in the education program for experience on advanced technology, self-development and enhancement of work capability. On the other hand, some respondents said that the education is time-consuming and that the education program does not fit their level. Thus, the education program should be developed in a way to minimize the spatial and temporal limitations of education targets and to improve understanding of non-majors by reflecting the demands of human resources in the industrial field.

In this study, using 16 ORA-IP (Ocean Reanalysis Intercomparison Project) data, we investigated spatial and temporal changes of net surface heat flux in the East Asian seas and presented a new ensemble net surface heat flux index. The ensemble net surface heat flux index is produced considering the data distribution and the standard deviation of each ORA-IP. From the correlation analysis with air temperature averaged over the Korean Peninsula, ensemble net heat flux around the Korea Strait shows the highest correlation (0.731) with a 3 month time lag. For the correlation study regarding precipitation over the Korean Peninsula, it also shows significant correlation especially in winter and spring seasons. Similar results are also found in comparison with climate indices (AO, PDO, and NINO3.4), but ensemble net surface heat flux data in winter season reveals the strongest correlation patterns especially with winter temperature and spring precipitation.

In line with the transformation of the shipping industry, the number of mixed-manning ships is on the rise - bringing foreign sailors aboard with their local sailors. During on-board work, a culture is formed according to mixed-manning, which leads to changes in on-board living environment. This causes various problems such as communication problems, and lack of education and training. In order to identify and solve problems caused by mixed-manning, this study presented a plan for systematic education of foreign seafarers. The officials in charge of the affairs of foreign sailors conducted questionnaire surveys at various shipping lines. The questionnaire survey results were analyzed using the IBM SPSS Statistic 26 program. Three improvement measures were proposed to solve the problems after identification of the types of education, education methods, and problems of foreign employees. This study revealed that it is imperative to systematize related education of foreign seafarers based on the results of the survey.

Approximately 4,000 vessels including sea trial ships per day are passing, entering or departing from Korea coastal waterway. Sea trial ships have erratic navigating patterns such as quick turning, crash stop and do not communicate with other vessels in appropriate time, so sea trial ships are often to expose dangerous situation such as collision in heavy traffic area. To identify the sea trial vessel's risk factors, this paper surveyed marine traffic volumes for 7 days in Korea harbour & coastal waterway, and it analyzed marine accident rate and intended to identify the risk degree of passing vessels. After that, this researched how many sea trial ship's traffic and what is the sea trial risk among sea trial items. We also conducted survey questionnaire and identified risk factors of sea trial ship. So this paper aimed to enhance the safety of korea coastal waterway to prevent sea trial ship's marine accident.

This study presents a descriptive statistical analysis on grade characteristics and employment rates of three ocean-related departments at a university. The ocean-related departments belong to the same college along with the other six departments. To obtain the correlation between the grade characteristics and employment rates, we carried out the followings. Firstly, four-year employment rates and six-semester GPAs (grade point averages) were obtained from the nine departments. Secondly, the box-and-whisker plots were constructed for each data set to capture the grade characteristics (mean, the first quartile, median, third quartile, whisker+, and Q3 box). Finally, the grade characteristics and employment rates were correlated. It is shown from the correlation analysis that the employment rate has a positive linear relation with the mean or third quartile, while the rate has a negative linear relation with the whisker+ or Q3 box, for the ocean-related departments possibly because these departments have higher regular employment rates than those of the other six departments.

I have investigated questionaire concerning to the view of worth and construction of consciousness as to boarding system collegian who will employed in fisheries and maritime industries. The results were as follows; It appeared 38.9% that most collegian had a firm subjectivity about enrolled motive, selection of department, they had selected department according to the neighborhood recommendation, own squired score rather than the adaption and prospection, also it was appeared 55% that they had not satisfied with attending to their college, accordingly, the effectiveness of education were demolished in such aspects. It was appeared 74.3% that the education of fisheries and maritime college were divided into theory and practice pertinently also, 77.1% that modulate both technical education and human like education but as a general rule, the education of ocean going liscensed officer was appeared 7.1% only so that, the reformation of the curriculum and contents of education would be needed. As to the relation between professors and collegian, it was appeared 38.4% that well understanding professor, 18.1% that well teaching professor, 13.3% that they having humanlish relation with professor, 30.6% that they will benefit to vocational selection. consequently, the professor have to brings up the harmony on dint of education and industries. The things which collegian think to be worth were 43.6%, intercourse of friend 30.3%, circle activity. 6.6% listening lecture, also, the leisure activity after school were 74.7% with friends. 16.4% alone. consequently, the professor has to guide of leisure activity after lesson. most collegian has a good relationship with their parent(91.6%) but the respond with bad relationship was 8.4%. The most serious agony which collegian think about is vocational problems (48.9%), the other sex problem(22.5%). The objects consult with agony was aquaintance(54.9%). The parent(5.1%), professors(2.3%), the collegian who did not consult with agony was 20.9%. The parents and the professor is not object consult with their agony. so that, the professors has to strengthen the education according to the human nature. As to job after graduation of such college, collegian who wish to be taken job on the fisheries and maritime industry were 50.5%, on the contrary, the collegian who wish to be taken a job no relation with his major subjects was 29.1% especially, the collegian who want to be embarked was 26.3% (fisheries 23.3%, maritime 30.5%). so that, we must adopt the counter plan for the globalization and effective investment on the fisheries and maritime college.
