  • In university education, the choice of major class plays an important role in students' careers. However, in line with the changes in the industry, the fields of major subjects by department are diversifying and increasing in number in university education. As a result, students have difficulty to choose and take classes according to their career paths. In general, students choose classes based on experiences such as choices of peers or advice from seniors. This has the advantage of being able to take into account the general situation, but it does not reflect individual tendencies and considerations of existing courses, and has a problem that leads to information inequality that is shared only among specific students. In addition, as non-face-to-face classes have recently been conducted and exchanges between students have decreased, even experience-based decisions have not been made as well. Therefore, this study proposes a recommendation system model that can recommend college major classes suitable for individual characteristics based on data rather than experience. The recommendation system recommends information and content (music, movies, books, images, etc.) that a specific user may be interested in. It is already widely used in services where it is important to consider individual tendencies such as YouTube and Facebook, and you can experience it familiarly in providing personalized services in content services such as over-the-top media services (OTT). Classes are also a kind of content consumption in terms of selecting classes suitable for individuals from a set content list. However, unlike other content consumption, it is characterized by a large influence of selection results. For example, in the case of music and movies, it is usually consumed once and the time required to consume content is short. Therefore, the importance of each item is relatively low, and there is no deep concern in selecting. Major classes usually have a long consumption time because they have to be taken for one semester, and each item has a high importance and requires greater caution in choice because it affects many things such as career and graduation requirements depending on the composition of the selected classes. Depending on the unique characteristics of these major classes, the recommendation system in the education field supports decision-making that reflects individual characteristics that are meaningful and cannot be reflected in experience-based decision-making, even though it has a relatively small number of item ranges. This study aims to realize personalized education and enhance students' educational satisfaction by presenting a recommendation model for university major class. In the model study, class history data of undergraduate students at University from 2015 to 2017 were used, and students and their major names were used as metadata. The class history data is implicit feedback data that only indicates whether content is consumed, not reflecting preferences for classes. Therefore, when we derive embedding vectors that characterize students and classes, their expressive power is low. With these issues in mind, this study proposes a Net-NeuMF model that generates vectors of students, classes through network analysis and utilizes them as input values of the model. The model was based on the structure of NeuMF using one-hot vectors, a representative model using data with implicit feedback. The input vectors of the model are generated to represent the characteristic of students and classes through network analysis. To generate a vector representing a student, each student is set to a node and the edge is designed to connect with a weight if the two students take the same class. Similarly, to generate a vector representing the class, each class was set as a node, and the edge connected if any students had taken the classes in common. Thus, we utilize Node2Vec, a representation learning methodology that quantifies the characteristics of each node. For the evaluation of the model, we used four indicators that are mainly utilized by recommendation systems, and experiments were conducted on three different dimensions to analyze the impact of embedding dimensions on the model. The results show better performance on evaluation metrics regardless of dimension than when using one-hot vectors in existing NeuMF structures. Thus, this work contributes to a network of students (users) and classes (items) to increase expressiveness over existing one-hot embeddings, to match the characteristics of each structure that constitutes the model, and to show better performance on various kinds of evaluation metrics compared to existing methodologies.

  • The number of schools that implement English medium instruction (EMI) to improve students' English proficiency has been increasing. Despite the increasing popularity of EMI, little attention has been paid to evaluating the effectiveness of EMI and its impact on students and instructors. This study explores these issues, focused on the case of the College of Engineering at Y University. A survey questionnaire was administered to 19 engineering professors who offered EMI courses in the Fall of 2003. The survey results show that: 1) the professors perceive that students' low English proficiency is a large obstacle to successful implementation of EMI, and that pre-EMI language courses are needed to prepare students for EMI. 2)Though the professors expressed confidence in their English proficiency, they indicated that they felt quite a lot stressed at teaching EMI courses; hence, support of the school administration is needed to help faculty offering EMI courses. 3)To improve students' English proficiency, native-speaking language instructors are needed to provide feedback on students' written and spoken English.

  • Objectives : This study evaluated the medical communication skills of trainee doctors and analyzed the relationship between medical communication skills, self-efficacy on clinical performance (SECP) and empathy. Methods : A total of 106 trainee doctors from a university hospital participated. The questionnaire comprised self-evaluated medical communication skills, modified SECP and the Korean version of the Jefferson Scale of Empathy-Health Professionals version. The mean difference in medical communication skills scores according to gender, age, division (intern, internal medicine group or surgery group) and position (intern, first-/second- and third-/fourth-year residents) were analyzed. Pearson correlation coefficients were determined between medical communication skills, modified SECP and empathy. The effects of each variable on medical communication skills were verified using the structural equation model. Results : There were no statistically significant mean differences in self-evaluated medical communication skills according to gender, age, division or position. Medical communication skills had a significant positive correlation with modified SECP (r=0.782, p<0.001) and empathy (r=0.210, p=0.038). Empathy had a direct effect on modified SECP (β=0.30, p<0.01) and modified SECP had a direct effect on medical communication skills (β=0.80, p<0.001). Empathy indirectly influenced medical communication skills, mediating modified SECP (β=0.26, p<0.05). Conclusions : Medical communication skills are an important core curriculum of residency programs, as they have a direct correlation with SECP, which is needed for successful treatment. Moreover, the medical communication needs a new understanding that is out of empathy.

  • Currently Science and technology are changing so fast these days, educating competent and creative person, majoring in natural sciences, including mathematics., becoming more and more important. But, in Korea, there are many problems in high school and university education program, so performance level in mathematics is decreasing and avoiding mathematics and natural sciences is increasing. Naturally the numbers of science oritented students in high school are decreasing and ability in mathematics, in particular calculus, is decreasing. Hence, the above situation leads to a reduction of scientific manpower. In this point of a view, we analyse the situation of the downturn of the ability of the science, especially calculus, among engineering majored freshmen. We also study many data reported by Ministry of Education and Science, Korea and scholar societies. From this study we conclude that the essential rerasons for the above situations are curriculum and the system of the entrance examination of the university, and we give suggestions for solutions of such a situation.

  • The purpose of the study was to present basic data of curriculum of PACS (Picture Archiving and Communication System) and to propose improved directions. To research clinical PACS education needs, radiological technologist who related on PACS was surveyed in 12 (55%) of capital area, 6 (27%) of middle area and 4 (18%) of southern area of Korea and for the medical institutes, 8 (36%) of over 1000 beds, 10 (45%) of 500 to 1000 beds and 4 (19%) of less 500 beds. And, to research the status of university education the survey was conducted in 6 of capital area, 6 of middle area and 6 of southern area. As a result, 95.5% of respondents in radiological technologist group thought that giving precede education for PACS and enlarging state-exam would be necessary. In university group, 78% of respondents answered that PACS was equipped and, 82% of them answered that it is very important to study PACS as major. Many universities, however, did not standardize major title and contents so a study about them needs to be followed up.

  • The purpose of this study is to analyze and diagnose the curriculum framework of dental hygiene department. Through document analysis process, this study found several empirical data which could give us a clue to understand characteristics of curriculum changes and factors which have impacts on those changes in curriculum at college level. In this study, we could conclude that even curriculum changes at college level had been influenced by social changes like extention of academic years from 2 years to 3 years and changes in licensure test at national level. And also, essential issues in college curriculum like amount of credits, course titles, and requirements-electives distinction etc. also were changed in accordance to social changes and requests. This study found that there is many difference of objectives, credits and course titles among colleges. For that, colleges will form a consultative group under the college level. Based on these results, we can suggest that college curriculum should be flexibly and effectively adapted to changes coping with social and policy changes.

  • This study analyzed the curriculum and clinical practicum of the department of clinical laboratory science in Korea. The 2017 educational curricula of all 3-year and 4-year universities were analyzed. Clinical practice was conducted by a questionnaire. As a result of curriculum analysis, the 3-year curriculum was able to grasp the curriculum that focused on the national examinations of medical technologists, and the 4-year curriculum was open to a variety of subjects reflecting the changes in the future, but only at a few universities. In addition, the autonomous enrollment application made it possible to take a national examination without enrolling in courses that students find difficult in major courses. In the case of clinical practice, it was difficult to standardize in various practical institutes, practice periods, and practice credits. Therefore, it will be necessary to standardize the composition of the credits according to the duration of clinical practice and the duration of education. Moreover, is necessary to revise the curriculum in consideration of medical technologist job analysis and clinical field, and it will be necessary to standardize the curriculum and clinical practice model through the Medical Technologist Evaluation Center.
