Engineering structures usually suffer from cracks. The crack geometry has an influence on the structural mechanical properties and subsequent crack propagations. However, as an extensively utilized method in fracture analysis, the extended finite element method provided by Abaqus fails to output the specific location and dimensions of fractures. In this study, a technique to capture the crack geometry is proposed. The technique is based on the invariant level set method (I-LSM), which can avoid updating the level set function during crack development. The solution is achieved by an open-source plug-in programmed by Python. Three examples were performed to verify the effectiveness and robustness of the program. The result shows that the developed program can accurately output the crack geometry in both the 2D and 3D models. The open-source plug-in codes are included as supplementary material.

This study was performed to investigate the level of importance and performance of patient education perceived by patients and nurses. The subjects consisted of 108 patients and 106 nurses in one university-affiliated hospital in Daegu, from February 1 to February 5, 2002. Data were collected through self-report questionnaires which were constructed to include the level of importance and performance of patient education. The data were analyzed by an SPSS program. 1) The level of importance of patient education perceived by patients and nurses was high, but the level of performance of patient education was relatively low. The level of importance and performance of patient education perceived by patients and nurses ranked as the highest in the area of diagnosis and treatment. 2) The level of importance and performance of patient education perceived by patients was not different according to general characteristics. The level of importance and performance of patient education perceived by nurses was different according to age and the working unit and the level of performance of patient education was different according to clinical career and job position. These results suggest that the level of importance of patient education perceived by patients and nurses was different to the level of performance of patient education perceived by them. Therefore nurses should actively provide patients with the educational program based on the importance of patient education perceived by patients.

PURPOSES : Recently, the mechanistic-empirical overlay pavement design program that is linked with Korea Pavement Research Program (KPRP) has been developed. This paper focused on establishing the framework and developing the program for the asphalt overlay design over the existing asphalt concrete pavement. METHODS : The overlay pavement design program developed in this study was investigated to assess the sensitivity to various pavement conditions, such as the damage level and thickness of existing layers. In addition, the actual overlay design on currently performing pavement was carried out as a practical example. RESULTS : From the sensitivity analysis, it was found that the thickness and damage level of existing asphalt layer mostly affect the overlay design results. In addition, under the same condition, the overlay pavement would better perform in cold region. From the overlay design with the actual condition, it is noted that the overlay thickness varies depending on the given condition. CONCLUSIONS : Based on various evaluations, it was concluded that the overlay design program developed in this study is a reliable and reasonable tool to be used in the actual pavement design.

In order to foster creative convergence talents in the era of the 4th industrial revolution, universities are changing from knowledge-oriented education to competency-oriented education, and the maker education program is attracting attention as a new educational method. Through maker program education, we tried to find out the level of convergence, creativity, caring, and communication competencies. A survey was conducted from May 2nd to May 13th, 2022 for 2nd and 3rd grade students in the Department of Radiology and Sports and Leisure who participated in the Maker Education Program at S University in Daegu City. Research results Convergence competency is 3.35 ± 0.78 points before maker program education, 4.37 ± 0.61 points after education, creative competency is 3.28 ± 0.78 points before maker program education, 4.07 ± 0.69 points after education, and caring competency is 3.71 ± 0.80 points before maker program education Points, 4.25 ± 0.64 points after training, and communication competency were 3.61 ± 0.70 points before maker program training and 4.16 ± 0.63 points after training. There was a statistically significant level difference in all four competencies compared with before training, and the level after training was improved (p<0.05). Through the operation of the maker education program, it was possible to see the effect of cultivating convergence, creativity, caring, and communication competencies. The maker education program can be seen as education for nurturing creative convergence talents in the era of the 4th industrial revolution, and I think that various maker education programs should be operated for more university students.
