As we have become more interested in 'competency' that means ability to do something around the world, the competency of the best performers has also been introduced in the university curriculum as a concept of core competency. Research continues on why this competency-based education is needed compared to existing academic-oriented education, how it can be introduced into existing curricula, and how it can be developed and evaluated in detail. This study develops and validates core competency assessment tools that can diagnose core competencies of engineering students. Therefore, this research paper conducted a literature review related to core competencies and also core competency assessment tools of university students. It seeks to explore the implications of core competency assessment tools for engineering students and then lay the foundation for competency-based teaching and learning at engineering colleges. And also it defines the concepts of core competencies and each core competency of engineering students through prior research analysis of competence, core competence, and core competence of university students. The primary core competency assessment tool consisted of sub-factors and questions of core competencies. It were modified through the expert validation of the primary one and then it was used as a core competency assessment tools for preliminary investigation. The core competency assessment tools for engineering students are consisted of 6 competencies, 22 sub-factors, and 91 questions. There are core competencies as follows: engineering basic competencies, major engineering competencies, self-management competencies, communication competencies, interpersonal competencies, global competencies. The preliminary survey was conducted on 426 engineering students attending the Engineering Education FESTA 2019.

A detector module measuring the depth of interaction(DOI) was designed to improve the spatial resolution of positron emission tomography(PET). The scintillation pixel array consists of two layers, and a light guide is inserted between the layers to make the light generated through the gamma-ray event different for each layer. There are four light guides, and one light guide is designed to be coupled to a 2 × 2 array of scintillation pixels. The light generated from the top layer is moved to the photosensor with a wider distribution through the light guide, and the light generated from the bottom layer is incident on the photosensor with a narrower distribution than the top layer. When a flood image is reconstructed based on the signals obtained from the photosensor by different distributions, scintillation pixels are imaged at different positions for each layer. To verify this, a DETECT2000 simulation tool that simulates the behavior of light in a scintillator was used. By designing a scintillation pixel array, a detector consisting of a light guide and a photosensor, a gamma ray event was generated in all scintillation pixels to obtain a flood imgae. As a result, it was confirmed that the top and bottom layers were imaged at different positions and completely separated. When this detector is applied to PET, it is considered that image quality can be improved through imporved spatial resolution.

This paper examines the material culture of the Goryeo-Joseon Period through changes in the design and crafting of the earpick. In Chapter 2, terminology regarding earpicks is presented, and the culture of using earpicks is examined through fragmentary literature of the late Joseon Dynasty. Earpicks were first a personal hygiene tool, and, secondly, they played a symbolic role as a style accessory used by men, analogous to the fan carried by women of the time. In Chapter 3, earpick form are classified by period, and characteristic decorative techniques for each form are examined. During the Goryeo Dynasty, earpicks were sanitary tools, and, according to their form, they were classified into single and complex types. From Unified Silla to Goryeo, there is an angled type of connecting rod, and in the Goryeo period, there appeared earpicks with colorful decorations on the handle, completely forged earpicks with a thin and long shape, and earpicks which were part of multitools. Common decorative techniques include line expression, gold plating, cheophomun on the background, and inlay. Earpicks of the Joseon Dynasty are classified into sanitary tools or ornaments, according to their purpose of use. Sanitary tools are divided into single type and complex type, and earpicks used as ornaments include headdress, norigae, and sunchu. For earpick accessories, headdresses and norigae were used for women, and sunchu was used for men. The decorative techniques of earpicks during the Joseon Dynasty were mainly seen in the headdress earpicks. They were decorated with various colors in the Cloisonné method or bejeweled. Research on everyday tools among crafts is lacking; greater attempts to read the flow of time and approaches to material culture through everyday tools should be made.

Among them, 158 students who completed the survey were included in the analysis. The tool for measuring global citizenship was comprised of knowledge, skill, attitude, and willingness to practice. The data were analyzed using the SPSS 26.0 program, and the statistical significance was set to p<.05. Results : Among the study's participants, there were 123 females (77.85 %). By grade, there were the most juniors, with 68 (43.04 %). There were 53 (33.55 %) seniors, 28 (18.35 %) sophomores, and eight freshmen (5.06 %). Among all participants, 52.53 % had experience in global citizenship education, and 63.92 % had experience in activities related to global citizenship. Because of analyzing the changes in global citizenship before and after overseas volunteer activities, "skill" increased the most, from 3.51±.65 points to 4.34±.56 points (p< .001). Due to analyzing changes in global citizenship before and after overseas volunteerism, the knowledge and attitude of freshmen were statistically significantly positive, with 1.17± 1.23 (p=.011) and 1.41±1.22 (p=.008), respectively. Participants with global citizenship experience had a significant change in attitude (p=.018). Conclusion : It was confirmed that the overseas volunteer activities of undergraduate students in the university brought a positive change to global citizenship. Providing opportunities for global citizenship education and activities in elementary, middle, and high schools in the future will maximize the effects of overseas volunteer activities to improve global citizenship.

The purpose of this study is to develop and evaluate a dietary education program to improve the caring ability and multicultural acceptance of middle school students. Based on the instructional system design of ADDIE model, the dietary education program was developed to contain five sessions including four theoretical lectures and one lab session. Visual thinking technique was used to train students to express their thoughts and emotion by writing and drawing. The dietary education program was conducted for four weeks (from November 19 to December 14, 2018) at a middle school located in Seoul on a total of 69 middle school students, out of which 34 were assigned to an experimental group and 35 were assigned to a control group. Separate paired t-test were conducted for the experimental group and the control group, respectively, to determine the changes in caring ability and multicultural acceptance scores before and after the dietary education. There were significant increases in caring ability (dietary-, emotional-, behavioral- and cognitive caring) and multicultural acceptance (diversity, relationship and universality) scores among the experimental group after the dietary program. However, no differences were observed among the control group. The results indicate that the dietary education program can be an effective tool to improve caring ability and multicultural acceptance of middle school students.

Safety accidents in the construction industry account for the highest percentage of all industries; and thus, it is encouraged to introduce a virtual reality (VR)-based experiential education system into the basic occupational safety and health training for construction as a way to solve the problem. However, there are some limitations such as a lack of competent workforce, and insufficient content and equipment for VR-based construction safety education. In this background, this study aimed to analyze the difference in learning effect between the CG-based experiential VR education (direct method, type B) and the existing photo-based audiovisual VR education (indirect method, type A), in which a CAMIL (Cognitive & Affective Model of Immersive Learning) theory was used as objective assessment tool. The learning effect of the direct education method (type B) was found to be superior to that of the indirect education method (type A) in terms of all areas in the CAMIL theory. It is expected that the VR-based experiential construction safety education will increase the learning effect of construction workers.

As the age increases, the oral cavity, that is, the teeth and periodontium, also begin to age, and accordingly, a preparation process is required. The preparation process is an important period for oral health management to start continuously with oral health education consisting of knowledge, attitude, and behavior from the 20s. Therefore, to design a clinical dental hygiene course for patients who visited a dental clinic in Gyeonggi-do and received continuous care in an oral health care room after treatment, we tried to analyze the data of the dental hygiene assessment. As a dental hygiene assessment tool, based on personal information and general medical history, dental visit experience, bleeding on probing(BOP), bad breath measurement, phase contrast microscopy, and O'Leary index were performed. The number of subjects who had dental visits was 75.4% and those without experience were 24.6%, and as a result of the periodontal examination, generally bleeding was found in 76.3%. In preventive oral care, the stage of dental hygiene assessment in the 20s is an important first step. From this point on, it is an important time to be systematically habituated so that you can take responsibility for your own oral condition. Therefore, in this study, the results of dental hygiene assessment through oral examinations of subjects in their 20s are derived and presented as basic data for the development of dental hygiene performance competency of dental hygienists during the clinical dental hygiene process in oral health education and oral health management.
