The purpose of the study is to provide an analysis of lexical, syntactic, and cohesive features, which were utilized to distinguish written products of L2 writers in the individual writing task from those in the group writing one using Coh-Metrix. In addition, the study attempts to explore linguistic differences in their written outputs with regard to their L2 proficiency and the correlationships between receptive lexical knowledge and productive lexical knowledge. A total of 105 Korean university students participated in this study. Results show that L2 learners’ written outputs varied in several variables used in this analysis such as lexical diversity and word frequency. L2 learners in the individual task yielded more cohesive texts, and they were able to incorporate more difficult words into their written products. Meanwhile, learners in the group task produced longer texts with using more logical and temporal connectives. When proficiency level was considered, L2 learners at the advanced level did not produce more cohesive texts, but instead produced more syntactically complex texts. The scores of productive lexical knowledge in the individual task positively correlated with those of receptive lexical knowledge from two different vocabulary tests. Meanwhile, the scores of productive lexical knowledge in the group task did not yield the similar results. The results implied that Korean university learners in the individual task were more task-oriented and produced a better written output.
Technology is changing the way of navigation. New technologies for communication and navigation can be found on virtually every vessel. System architectures define structure and cooperation of components and subsystems. IMO, IALA, costal authorities, technology provider and many more actually propose new architectures for e-Navigation. This paper looks at other transportation domains and technical as normative requirements for e-Navigation architectures. With the aim of identifying possible synergies in the research, development, certification and standardization, this paper sets out to compare requirements and approaches of these two domains with respect to safety and security aspects. Since from an autonomy perspective, the automotive domain has started earlier and therefore has achieved a higher degree of technical progress, we will start with an overview of the developments in this domain. After that, the paper discusses the requirements on automation and assistance systems in the maritime domain and gives an overview of the developments into this direction within the maritime domain. This then allows us to compare developments in both domains and to derive recommendations for further developments in the maritime domain at the end of this paper.
