The internal deck structure of turtle ship has been investigated with the following approach manner. Firstly the 5 species of turtle ship are identified by examining the characteristics of 5 turtle ships revealed by the librarian or paintings. Secondly the centers of gravity and buoyancy for each type are calculated to evaluate the turtle ship's buoyancy stability. Thirdly the optimal deck structures for 5 turtle ships are additionally assessed from the viewpoint of the interoperability of soldier's missions to get more meaningful conclusion. From the results obtained by the well refined analyses above, one can identify that Changjeguyseon and Lee Chung Mu Gong descendent family's turtle ship possess one layer deck, and the tongjeyoung and jwasuyoung turtle ship consist of 1 and half story deck, and the one disclosed by Yoon has 2 story structure.

This study focuses on two analysis: direct cognition of effectiveness of internship practicum, difference of career attitude maturity. The purpose of this experimental case study is to find out the practical problems of Internship education as a field-study of LIS by applying Job-Shadowing Internship methods. The results reveal that 71% of interns responded the positive effects of Job-Shadowing, but the effects to the career attitude maturity was not statistically significant. The implications of the case study are as follows; (1) systematic pre-instruction and orientation from the department are the critical factor of internship, (2) practicum guidelines(PEP), which is provided by the person in charge of tasks in internship institutions is the another important factor, and finally, (3) tools for measuring the effectiveness of internship is required for LIS practicum major course development.
