The purpose of this study is to suggest implications for the development and revision of future teaching materials for mathematically gifted students by using network text analysis of secondary mathematics materials. Subjects of the analysis were learning goals of 110 teaching materials in a gifted education center in science attached to a university from 2002 to 2014. In analysing the frequency of the texts that appeared in the learning goals, key words were selected. A co-occurrence matrix of the key words was established, and a basic information of network, centrality, centralization, component, and k-core were deducted. For the analysis, KrKwic, KrTitle, and NetMiner4.0 programs were used, respectively. The results of this study were as follows. First, there was a pivot of the network formed with core hubs including 'diversity', 'understanding' 'concept' 'method', 'application', 'connection' 'problem solving', 'basic', 'real life', and 'thinking ability' in the whole network from 2002 to 2014. In addition, knowledge aspects were well reflected in teaching materials based on the centralization analysis. Second, network text analysis based on the three periods of the Mater Plan for the promotion of gifted education was conducted. As a result, a network was built up with 'understanding', and there were strong ties among 'question', 'answer', and 'problem solving' regardless of the periods. On the contrary, the centrality analysis showed that 'communication', 'discovery', and 'proof' only appeared in the first, second, and third period of Master Plan, respectively. Therefore, the results of this study suggest that affective aspects and activities with high cognitive process should be accompanied, and learning goals' mannerism and ahistoricism be prevented in developing and revising teaching materials.

This study investigates the relationships among learning motivation, learning immersion, and academic achievement in college-level nursing students who give non-face-to-face online lectures. The data for this study were collected using questionnaires given to 147 students attending four-year nursing colleges at two universities. For the data analysis method, descriptive statistics, t-test, ANOVA, the Scheffe test, Pearson's correlation analysis, and multiple regression analysis were used. As a result of the study, the average motivation was 101.29±12.18 points, learning commitment was 72.02±8.03 points, and academic achievement was 31.31±4.06 points. The relationships among learning motivation, learning commitment, and adaptation to college life showed significant positive correlations. In the results of multiple regression analysis, factors influencing the academic achievements of nursing students were found to be learning motivation and learning commitment. Therefore, in order to increase academic achievement in nursing college students, it is necessary to develop a specific strategy to improve learning motivation and to develop various activities and programs to immerse students in learning.

This study analyzed cases of teaching consulting in the cyber university field and activated it in a remote university in the right direction to contribute to the development of high quality contents. This study analyzed the instructional consulting data of the Center for Content Quality Management at A Cyber University in Chungnam area and interviewed researchers working at the center using the phenomenological approach based on the data. This study showed that the professors participating in instructional consulting had many problems, but they were relatively active in improving the quality of the lectures. They wanted to know the teaching methods in the unfamiliar environment of remote universities. In addition, the researchers had difficulty in delivering feedback to the instructor through the process of exploring images taken several times with the objective framework of lecture evaluation. To allow better communication, it was necessary to form rapport between the instructor and researcher. Unlike general universities, cyber universities have features and limitations in that they only take cameras in the classroom without learners and proceed with class consulting. Therefore, the teachers have a feeling of burden about shooting and recording, but they are less than general university teachers, and are more willing to engage in class consultation more actively. In this study, the results of the research was discussed and the proposal of cyber universities' instruction consulting and the effective plan is proposed.

The purpose of this study is to examine the status of data librarian-related course syllabi in the 2023 American Library Association(ALA)-accredited degree programs in Library and Information Science (LIS). The present study examined LIS course syllabi related to data librarian including course titles, course objectives, course descriptions, weekly topics and assignments. ALA-accredited LIS programs offer various courses in data librarianship such as data management and curation, data analysis and visualization, metadata, information services, research methods, library management, academic libraries, computer programming and databases. This study collected 184 syllabi from the ALA-accredited LIS programs and selected and analyzed 127 syllabi that are related to data librarianship. The study examined 3,045 course titles, 2,559 course description from 61 LIS degree programs overseas, and 1,330 course titles from 37 LIS degree programs in Korea. This study found that LIS degree programs both in Korea and overseas offer various courses for data librarians. The researcher hopes the findings of this study will be used as a starting point to develop or redesign courses related to data librarianship in the information field.

Although the subject of Mechanical Drawing is very important in mechanical engineering education, it is hard to teach the subject effectively, because it needs to carry out lectures and labs in parallel and needs substantially large portion of CAD lab time. In the department of Mechanical Systems and Design Engineering of SNUST, Project Based Learning is adopted to teach the subject of Mechanical Drawing. In this course, students experience to read and to draw drawings through the PBL project after the lectures on mechanical drawings. In this way, they can learn by heart the drawing skills and the operation of CAD software tools. In this paper, various PBL projects and teaching methods carried out in recent years are presented and the effects of the projects are discussed.

현재 섬진강 수계에서는 댐방류에 따른 하류하천의 하도추적은 수문학적 모형에 의해 운영되고 있으나, 하구의 조위 및 하천내 존재하는 수공구조물의 영향 그리고 지류에 의한 흐름분석을 위해서는 정교한 수리학적 모형이 필요하게 된다. 섬진강으로 유입하는 대표수계는 경천, 요천, 그리고 보성강이 있으며, 보성강의 상류에는 주암댐이 보성강의 유하량을 조절하게 되는 데 이를 반영한 모형구축을 지속적으로 수행할 예정이다. 또한 섬진강 하구유역에서는 조위에 의해 본류의 홍수위가 영향을 받게 되므로 이에 대한 영향도 분석하였다. 섬진강 하구에서는 여수관측소와 광양조위지점이 있는데, 두 지점 모두 일년치의 예측이 가능하게 되며 여수지점에서는 실시간 조위관측이 수행되고 있기 때문에 향후 두 지점의 조위결과값을 이용한 최적의 조위산정방법을 결정하게 된다. 본 모형은 하천에서 발생하는 부정류 수리학적 해석모형에 의해 다양한 수행결과를 제시하게 된다. 각각의 관측수위표지점과 비교한 결과 전체적인 경향에서는 합리적인 결과를 나타냄으로서 모형의 적합성을 확인할 수 있었다. 본 연구를 통하여 대상구간의 전체하도에 대한 적용절차 및 분석기법 등을 참조하여 다른 수계로의 확장이 가능하게 되었다. 단면변환 및 경계조건 산정방법, 모형의 수행 및 결과 분석 등이 댐방류 또는 지류의 유입을 고려한 합리적인 하천관리를 위한 방향을 제시할 것으로 판단된다.

In order to overcome the students' lack of information and experience, we developed a content planning tree that utilizes a decision tree. The content planning tree consists of a tree trunk creation step in which students select a theme and a story to develop, a parent branch generation step for selecting a category that can be developed based on the story, a child branch generation step for selecting the interesting "effect" method of producing the content effectively, a leaf generation step for selecting a multimedia expression 'element' to be visualized. The educational model was applied to game planning design and information visualization lectures, and provides examples of the categories, effects, and elements used in each lecture. The model was used for 145 team projects and the efficiency was confirmed by a step-by-step learning process.

일반적으로 전기강의 특성측정에는 Epstein frame과 Single sheet tester를 이용한 측정법이 사용된다. 그러나 위의 방법은 시료 규격이 매우 제한적이며 Sheet 형태의 시료를 요구하기 때문에 측정이 용이하지 못한 경우가 많다. 이러한 경우를 위한 측정법이 Ring test 측정법으로 시료에 제한이 적기 때문에 그 활용도가 매우 높으며 특히 Bulk 형태의 시료에 대해서는 거의 유일한 측정법이라 하겠다. 본 논문에서는 0.2Hz의 교번자계 여자를 통해 Bulk형 전기강의 특성 측정을 하였으며, 정현파 자속밀도 조건과 정현파 여자 전류 조건에서의 B-H특성과 철손을 측정, 비교하였다.

As the use of computer has become popular it is now essential also in designing tools that the common design tools we have been using are now disappearing. The educational institutions have long started using computers as teaching materials to help students adjust to the real world. Let us introduce a new educational method in drawing, one of the basic courses, using imputer application softwares together with application of the conventional drawing instruments.
