The current government strives to train those supposed to drive the national economy, and bridge the gap between qualification and industrial sites through competency-based qualification systems, not the educational background. In this regards, the government is planning to adopt the course evaluation qualification system. The course evaluation qualification system, on a basis of the NCS, is a system to qualify certain people completing the education and training fulling a specific requirement for a national technical qualification in case they meet the internally and externally assessed criteria. This can be seen as an attempt to practically link between job training and qualifications. The NCS model and learning module in the cadastral field are already utilized as the training and eduction in the specialized school and colleges. However, the current national technical qualification system is considered as a main system because the course evaluation qualification system has not been introduced yet. This study analyzed the process of the course evaluation qualification system, and conducted a survey to solicit feedback on introduction of course evaluation qualification system, Besides, the NCS evaluation model is presented in order for the introduction of course evaluation qualification system in the cadastral fields.

Purpose. This study developed a web-based wound care course for undergraduate nursing students and evaluated the course's content, system, and student-satisfaction. Methods. This study was done in three stages, the development of the web-based wound care course, the implementation and evaluation of the course. The course was developed based on the ARCS model. 80 under-graduate nursing students to Y University in Korea used the web-based wound care program during four weeks. After that, they completed questionnaires, evaluating the contents, system, and their satisfaction. Results. Eighteen learning objectives were used to create the web-based wound care course and the course was developed with 7 chapters and 20 subsections. The analysis of the questionnaires showed a mean score for content and system-related items of 3.04 each, out of a possible 4 points. Student satisfaction items had a mean score of 2.89. Conclusions. The web-based course allowed students access to the course anytime and anywhere, and according to their own learning abilities. However this advantage would only be possible when nurse educators develop qualitative web-based course to meet the demand of a complex health care system as well as the needs of the students and the effectively incorporate it into traditional lectures.

Ship's maneuverability is very important factor in safe ship handling and economical ship operation. Steering characteristics are consisted of course stability and maneuverability. Today in many advanced ship-building countries, they study ship's course stability, using model ship tests, such as straight line tests, rotating arm tests and Planar Motion Mechanism (PMM) etc., in tow in tanks. It is the purpose of this paper to provide ship's handlers with better understanding of steering characteristics and to help them in safe controlling and manevering . In this paper, the author simulated response of various vessels, running straight course with constant speed, and they are disturbed by small external disturbance of one degree yaw angle with no angular velocity . The author used the hydrodynamic derivtives resulted at tests of Davidson's laboratory in Stevens Institute of Technology, New Jersey, U.S.A. Course stability was evaluated and analyzed in various respects, such as block coefficient, ratio of ship's length to beam, draft and rudder area ratio etc. The obtained results are as follows : (1) The ship's course stability is affected by magnitude of block coefficient greatly. In case that the block coefficient is more than 0.7, the deviation varies at nearly same rate but the requistite time to reach the steady course is different. (2) The ship's course stability is affected by magnitude of L/B. When the dimensionless time reaches about 3, the deviation and requisite time to reach the steady course are influenced nearly same. After the dimensionless time is about 3, they change on invariable ratio. (3) The effect to course stability by L/T and RA' can be neglected. (4) The reason why thy VLCC and container feeder vessel are unstable on their course is that their block coefficient is generally more than 0.8 and the ratio of ship's length to beam is about 6.0.

Through this study, we aimed to capture the nature of a mathematics method course, called "the Curriculum Development and Teaching Methods in Mathematics Education" which is a pedagogy course for teaching for secondary school mathematics taught at a university located in a south eastern part of South Korea. The research participants include three junior students who took the methods course and a local high school math teacher with two professors. The research has three parts. First, we designed a method course to prepare the junior or senior students for a teaching practicum. The individual students gave a mini lecture about a secondary mathematical topic as a course requirement. Second, the three students watched a classroom video-clip of the high school teacher and analyzed his instruction before the actual classroom visits. Furthermore, by "Let's Learn" program for students, the course was associated with a local community through the students and so that they could visit the teacher's classroom three times to observe his math classroom teaching. The students discussed the difference between their own mini lectures and the actual math classroom teaching to develop an understanding of what it entails to teach an actual math class. Third, the first author supervised the students' activities in the program including their report for it to bring out their findings to the class of the method course. We found out this method course provided the students with the experience of various aspects of actual math lesson as well as learning theories about the pedagogy for teaching for secondary school mathematics. We conclude that this course gives a model for the method course in mathematics education for secondary school mathematics.

There haw been some courses related to science education for the graduate students, but almost the study for no instructional model and reading material development haw been pursunded in Korea. This study intended to discuss the discipline character of science education research for the systematic survey of concepts, principles and theories related to science education as the first put task, and designed an instructional model of the introductory survey course of science education at graduate level, and then proposed a developmental plan of a reading material for the course teaching aid. The main work of the study was to survey the foreign literature, but the subjective analysis of researcher's courses work during graduate study in abroard and some courses offered to undergraduate and graduate students in Korea by this researcher was quite helpful, even though which was not a strictly designed experimental research. Later it was found that this kind of study was not fitted to the traditional research style but worth while to try for the research in and teaching of "science education" as an area of discipline and professional activity.

A curriculum for teaching materials in Science Education was studied as a model for modified experiment on fundamental courses. Conscious effort can be made to desingn experiments that require minimum apparatus: that require low-cost equipment that can be made from cheap locally available materials. Computer-aided instruction programs at high school, freshman course level have been developed. The software package was consist of five programs: The program contains explanation and problems for the calculation of resonance energy, molecular structure, mole concept. Rutherford's experiment. thermodynamic processes. Special course equipment package explanation mole concept, Rutherford's experiment, thermodynamic processes. Special course were designed in Science Education with the understanding that to a certain extent science values would be covered in all of the modified experiments and program models.

For statistical microarray data analysis, clustering analysis is a useful exploratory technique and offers the promise of simultaneously studying the variation of many genes. However, most of the proposed clustering methods are not rigorously solved for a time-course microarray data cluster and for a fitting time covariate; therefore, a statistical method is needed to form a cluster and represent a linear trend of each cluster for each gene. In this research, we developed a modified hierarchical mixture of an experts model to suggest clustering data and characterize each cluster using a linear mixed effect model. The feasibility of the proposed method is illustrated by an application to the human fibroblast data suggested by Iyer et al. (1999).

In the era of the 4th Industrial Revolution, the interest in autonomous ship technology is increasing as high-tech technologies are being increasingly utilized throughout the industry. Therefore, we conducted a basic study on autonomous ships. In particular, a passenger ship model was produced and an autonomous navigation system was established by applying the ardupilot used for drones. The possibility of automatic control of the autonomous ship operations was confirmed by executing various voyage plans using the built model ship. In the performance test for maintaining the course the model ship could not follow the designated course straight and sailed up to 5.4 m away from the course while navigating in a zigzag (S-shape); however, after the parameters were modified, the deviation distance was reduced to a maximum of 1.8 m. In the turning performance test, the maximum diameter of the turning sphere was found to be approximately 9.3 m, but no significant change could be confirmed even after the parameters were modified. However, the results of our tests on slowing down the ship before arriving at the WP confirmed that the diameter of the turning sphere was reduced to a maximum of approximately 3.2 m. In order to evaluate the stopping performance, the last scheduled stopping position of all experiments was compared with the actual stopping position of the model ship and it was confirmed that the model ship stopped at a point at least 0.4 m and a maximum of 6.2 m away from the stopping position. In the future, improvement of course stability, turning performance, and stopping performance is required through modification and supplementation of various parameters. Moreover, a study on automatic berthing of the model ship through automatic control is planned.

This paper emphasizes writing education for engineering students should be communication driven writing education based on KEC2005. Communication driven writing for engineering students is essentially same as Technical Writing(TW) developed on the basis of ABET. Considering the current writing capability of engineering students and social need for various types of writing, TW education should be divided into two courses: basic and advanced. This paper deals with contents of a basic TW course in Myongji University, as a model case of a basic TW course for engineering students. It underlines various methods of prewriting that should be stressed and practiced in the TW class, because the prewriting step in the writing process determines the overall direction and structure of an essay. In particular, this paper introduces Power Writing(PW) which uses the structure of a paragraph as a means for providing building-blocks for the essay, employing logic, and ordering information arrangement in a paragraph. This paper also deals with important guidelines about sentence structure and word selection and proposes various applications of TW such as resume, interview, proposal, report, and presentation as a latter part of the basic course. Finally this paper highlights the etics of writing, such as plagiarism and the basic principles of quotation.

In this paper, we evaluated educational effects of H-STEAM group play contents(a course) and tried to suggest a convergent model for college liberal art curriculum. We opened a mixed course(math, art, engineering, and humanities) with team teaching for this purpose. For the test, we collected data from survey, K-W-L sheet, and reflection paper from 23 students who enrolled in this course. Students should do a team project during the course, propose a new group game, and write K-W-L sheet at the end of each session and reflection paper at the final stage. As a result, it is said that H-STEAM group contents had an effect on students' satisfaction and achievement. During the course, students made academic efforts and were able to construct convergent knowledge from the four fields. From this study, we are sure that H-STEAM contents can play a substitute role for the traditional liberal arts program and innovate the curriculum for the knowledge convergence society.
