This paper examines the correlation between midterm and final evaluations using quantitative assessment data from an online liberal arts course titled "Software and Computational Thinking" over four semesters. The course was conducted through pre-recorded video lectures, and the same conditions were maintained throughout the four semesters. The study results showed that the course satisfaction rate in the final evaluations was lower than that in the midterm evaluations across all assessment items. This is likely because improvements based on student feedback from the midterm evaluations were not implemented within the same semester, and the rate of insincere responses increased in the final evaluations. Moreover, objective evaluation items such as "Adherence to Syllabus" and "Relevance of Lecture Content" showed a statistically significant correlation between midterm and final evaluations. However, for assessment items where subjective judgment, such as "Lecture Comprehension", is important, no significant consistency was observed between midterm and final evaluations over the four semesters. The evaluation of subjective assessment items is closely related to the perceived difficulty of the lectures by the students, and in engineering-related courses, this connection is even stronger. Therefore, in the case of liberal arts courses in engineering, where students from various majors are enrolled, it is natural that the perceived difficulty of the lectures differs among students as the course progresses, and that the change in perceived difficulty between the midterm and final evaluations also varies. As a result, it is understandable that there is a lack of consistency in subjective evaluation items between the midterm and final evaluations. These findings suggest that to enhance student satisfaction and maintain consistency in course evaluations throughout the semester in engineering liberal arts courses, it is necessary to design and operate the lectures with differentiated practical content tailored to the academic backgrounds of the students.

The fourth industrial revolution calls for an integrated talent by improving working-level skills within the big framework of creativity and convergence. Therefore, university education focuses on solving the problem of practical ability education by improving employment ability. Based on this improvement in practical skills, this study is based on the field-based design curriculum of Capstone. Currently, the Capstone Design Course is being implemented at most universities, extending its scope to the fields of engineering, humanities, social studies and arts. However, there is a limit to the core concept of Capstone design education and capacity education developed in line with the foreign educational environment and applied directly to our nation's university education. In terms of overseas cases, the core focus is to develop practical, design, and prototype capabilities by forming a team among all grades and multidisciplinary institutions to support the capital and manpower of the industry. However, the nation's industrial linkage and curriculum have difficulties in carrying out multi-disciplinary education. In this study, students were asked to team up and solve the challenges that the industry needs based on the expertise acquired in the lower grade curriculum by applying majors and 3D printing through the first and second semester courses of the fourth grade to address these limitations. In addition, business skills for the process of creativity and leadership experience in our country through a suitable design capstone class to review the efficiency of education by applying a model. In order to achieve the purpose of Capstone design subject, the goal setting, class model composition, class model application, verification and evaluation, and final class model development procedures were carried out. Through this process, it will be used as a basic material for educating design class capstone design.

The purpose of this study was to investigate and analyze current educational requirements related to genetics curriculum(from June 2002 to September 2002) established at nursing institutions and to provide the basic data for the development of genetics science program at the undergraduate. Subjects of this study were comprised of twenty-three colleges of nursing in 4-year baccalaureate and thirty colleges in 3-year diploma programs. The results of this study were as follows : 1) 32 colleges offer courses related to genetics. 29 among 32 colleges have that integrated. Three schools have established completely independent courses of genetics. 21 colleges do not have any courses dealing with genetics. 2) The contents of courses related to genetics include: Congenital abnormalities, chromosomal aberrations, congenital metabolic disease, prenatal diagnosis and genetic counseling, genes and chromosomes, immune genetics, blood type and genetics, rule of genetics, variation in gene expression, the map of the human gene, gene linkage genetics, interaction of genes, single inheritance in order and genetic biochemistry. 3) For course credit, 14colleges(48.3%) offered at most 1 credit per course. The grade of student who can take the course, 51.7% were in their second year while 37.9% were in their third year. The majors of nursing faculty who taught the course were nursing(51.7%) and basic nursing science(17.2%). 4) As far as the need of opening the courses related to genetics, 36 colleges(67.0%) have made a 'need', 12 schools(22.6%) state 'dose not need'. 711e reason for need were the following development of bio engineering, increase number of patients who are related to genetics, recognition of the need in clinical nursing. 7 schools(13.2%) agreed to offer independent course in genetics but 39 schools(73.6%) are in disagreement with that. When the school offers the course with other courses, 27 schools(50.0%) are opening basic nursing science and 14 schools(26.4%) are opening nursing as an integrated courses. If the name of course was either genetic nursing(34.0%) or genetics(28.3%), the credits for the course was one or 2 credits. 33 schools(62.3%) students were in the first or second years. 41 schools(84.9%), the majors of the faculty who had taught the course were either basic nursing science(35.8%), nursing(28.3%) or basic medicine(24.5%). The contents of the course should include in that order: Chromosome aberrations, prenatal diagnosis and genetic counseling, congenital metabolic disease, congenital abnormalities, genes and chromosomes, the rules of genetics, immune genetics, interaction of genes, variation in gene expression, etc. The results and discussions of the study indicate that the entire curriculums need to be investigated with respect to contents of education, nursing curriculums and name of courses because of the increasing need of knowledge related to genetics in the clinical practice.

This study examines the wage level from a viewpoint of major-job match as part of an analysis on the skill mismatch problem in 4-year college graduates. The empirical analysis explicitly incorporate the sample selection bias as an econometric problem not only suggested but merely introduced in the earlier studies. This study also set up a major-job match variable, which was usually handled as a binary variable for analytical convenience, as a polychotomous choice variable in selection equation as provided by the survey. In particular, it considered multi-cohort survey on graduates of the years 1982, 1992, and 2002 for the empirical analysis. As a result of empirical analysis, the wage premium of a major-job match was identified. This result was consistent after the consideration of a sample selection bias and also after modeling the major-job match variable as polychotomously selective. Through an analysis classified by the major, this study identified a relatively high wage premium among Social Science, Engineering, and Science majors. However, there was a difference in the effect of selection among these majors. Also, by assessing cohort effects this study found that the skill mismatch had rapidly progressed in 1992, while difference between 1992 and 2002 cohorts are insignificant. The analysis suggests that wage level is better understood within the context of both sample selection and major-job match, and regardless of model specification the major-job match affects wage strongly.

Hankyong National University decided to introduce a track-based curriculum for a curriculum innovation as it switched a Polytechnic University system into a general University system. A TF(task force) team was formed to study a operation strategy of a track curriculum and the opinions of campus members and educationist were gathered. Such systematic preparation was performed for the introduction of the track. Based on those works, a track-based curriculum has been operating from 2012 spring semester. A track system defines that the curriculum in a department is divided into specific majors(or tracks) and the department/agency guarantees their expertise if the students complete the course of a specific major to increase the depth and expertise in the field of study or specific areas. Track means a set of customized courses that are demanded by the corporations, and the courses include basically specific education activities, levels of education, and educational contents required for job or position of the corporation. In this paper, any issues, that arose through the operations of the track-based curriculum at Department of Electrical, Electronic and Control Engineering in Hankyong National University, and their possible solution were presented.

The purpose of this study is to identify the basic scientific knowledge of in- and pre-service elementary school teachers, specific areas having insufficient knowledge and the reason for the lack of understanding. For the study, we analyzed the survey asking basic scientific knowledge to in-service elementary school teachers within an urban communities and pre-service elementary school teachers enrolling the first, the second and the third year in National University of Education. The results shows that there is the lack of understanding about scientific knowledge such as boiling points, perihelion, substances, and elements, which elementary school teachers should have exactly known. With regard to the age, an effort is required to increase scientific knowledge of the in-service teachers in 50's, compared to those in 20s' and 30s'. In the pre-service teachers, the average in the third year was significantly higher than that in the first and second year. Regarding the major background in high school, both of in- and pre-service teachers who completed the science course showed significantly higher average than those who completed the liberal arts course. In addition, regarding the major in the university, the average of the group with science and engineering major was higher than that of the group with other majors.

The materials used in a ship screw propeller are commonly made with brass. The seawater corrosion and seawater cavitation of the screw propeller reduces the propulsive performance of the ship. In screw manufacturing, the corrosion rust of the screw propeller is removed through a hand grinding method. The grinding process produces dust of the heavy metals from the brass. The dust creates a poor working environment that is harmful to the health of the workers. An automatic corrosionrust removing apparatus, using a blasting method, was developed for the improvement of screw polishing conditions and its working environment. The performance of this apparatus was investigated by surface roughness, weight loss rate, hardness, electrochemical corrosion resistance, and cavitation erosion, after removing of the corrosion rust under various blasting conditions. Two medias of alumina and emery were used in this experiment. The surface roughness and hardness of the screw were improved by this apparatus. The electrochemical corrosion potential (Ecorr) and current density (Icorr) were measured by the dynamic polarization method, using a potentiostat,under the conditions of surface polishing with grinding, blasting, wire brushing, and fine sand papering. The test results prove that the new corrosion rust-removing apparatus improves the surface performance of a screw propeller.
