  • 본 논문에서는 MPEG-21 디지털아이템 적응변환을 위한 시각 장애 서술자를 제안한다. 제안된 시각 장애 특성 서술자는 사용자가 가질 수 있는 시각 장애 특성인 저시력 장애와 색각 장애 특성을 포함한다. 제안된 서술자는 사용자의 시각 장애 특성을 충분히 서술할 수 있도록 시각 장애 증후 기반의 체계적인 시각 장애 서술 구조를 가지도록 하였고, 사용자가 용이하게 서술할 수 있도록 서술의 용이성 측면도 고려하였다. 본 논문에서는 제안된 서술자의 유용성을 증명하기 위해, 제안된 서술자를 이용하여 MPEG-21 프레임워크 내에서의 디지털아이템을 적응변환 실험을 수행하였다. 실험을 통해, 제안된 시각 장애 서술자가 시각 장애를 가진 사용자에게 향상된 접근성을 제공하기 위한 디지털아이템 적응변환에 유용함을 보일 수 있었다.

  • 설문조사에서는 대부분 단위무응답 또는 항목무응답이 발생한다. 무응답 발생비율이 높은 경우 무응답을 무시한 분석은 잘못된 결과를 초래할 수도 있으므로 무응답에 대한 특성 파악도 필요하다. 횡단자료에서는 항목무응답 특성에 대한 연구는 가능하나 단위무응답의 특성을 파악하기가 어렵다. 단위무응답의 특성을 파악하기 위하여 본 논문에서는 종단자료인 한국아동 청소년패널조사 중 중1패널자료를 이용하였다. 최근까지 공개된 한국아동 청소년패널조사자료를 이용한 논문들의 무응답 처리 실태를 파악하고, 그 중 단위무응답의 특성에 대하여 분석하였다. 이 자료를 이용한 논문에서는 대부분 단위무응답의 처리를 제거하는 방식을 취하고 있으며, 이 자료에서 제공하고 있는 가중치를 이용한 논문은 거의 없었다. 이에 단위무응답의 처리방법 중 가중치를 이용한 방법과 그 대상을 제외하는 두 가지 방법에 대해 여러 가지 특성들의 분석을 비교하였다. 많은 항목에서 두 가지 방법의 결과가 상이하게 나타났으며, 가중치를 이용한 경우가 제거법에 의한 결과에 비해 통계적으로 유의한 결과가 더 많이 나타나 무응답에 대해 많은 논의가 필요할 것으로 생각된다.

The subjects consisted of 569 nurses who work at a university hospital and 6 general hospitals in Daegu, Kyungpook and Kyungnam. The findings are as follows : The average item score of professional self concept was 2.68. The mean item scores of professional self-concept in each dimension were as follows: 2.77 for professional practice: 2.33 for satisfaction: 2.91 for communication. The average item score of job satisfaction was 2.79. The mean item scores of job satisfaction in each dimension were as follows: 3.39 for interaction : 3.27 for professional status; 3.19 for autonomy : 2.90 for doctor-nurse relationship: 2.57 for administration: 2.41 for task requirements: 2.16 for pay. The stronger a subject's professional self-concept, the stronger the job satisfaction. The relationship between general characteristics and professional self-concept shows a significant difference with regard to age, religion, marital status, period of nursing career, and position. The relationship between general characteristics and job satisfaction shows a significant difference with regard to age, religion, educational level, work setting, period of nursing career, position, and region. In conclusion, this study suggests that we need to develop a program for improving professional self-concept of clinical nurses through nursing education.

  • 본 연구의 목적은 선다형 적성검사에서의 선택지 위치, 선택지 지문 길이 및 문항 진술 유형에 따른 문항 특성차이를 알아보는데 있다. 이를 위해 H대학의 적성평가 수시 전형 사전검사로 개발된 적성평가 80문항을 전국 80개 고등학교에 재학중인 고등학교 3학년생 3120명(인문계열-1650명, 자연계열-1467명)에게 실시하였다. 분석결과, 정답이 외곽치(1, 4번 선택지)보다 중앙치(2, 3번 선택지)에 위치할 경우 추측도가 높았고, 옳은 것을 고르는 문항보다 옳지 않은 것을 고르는 문항에서 변별도가 더 높았다. 또한 선택지의 길이가 길수록 선택지 선호도가 높은 것으로 나타났다. 마지막으로 선택형 적성검사에 대한 새로운 접근과 관련해서 본 연구의 의의와 추후 연구 방향을 논의하였다.

  • Purpose: The purpose of this study is to classify the characteristics of each item of CIST evaluation and to find out the degree of recognition of the characteristics of the cognitive tool. Methods: This study was conducted for occupational therapy majors at M University located in Gyeongsangnam-do. The data collection from May to June 2021. Total of 25 copies of the data were finally analyzed, SPSS Statistics 26 was used for data analysis. Results: As a result of the study, the significance level was visual reasoning 1 test strip and the visual reasoning 1 tool. In the relationship between the correspondence 1 figure simulation sheet and the figure simulation tool for each item and statistically significant, and the correspondence 2 visual reasoning 2 sheet. Visual reasoning 2 sheet and visual reasoning tool also showed that was found to be statistically significant. The correlation for visual reasoning 1 sheet and the visual reasoning 1 tool, reasoning 2 tool and visual reasoning 1 sheet, and the visual reasoning 2 tool and the verbal reasoning sheet. Conclusion: In this study, in the CIST items that may be difficult, it is better to attach the actual tool rather than the verbal explanation of the test paper to increase the efficiency of the test and the understanding of subjects with mild cognitive impairment. It was implemented by applying the tool, and it was found that the use of the tool in the visual reasoning item showed a high correlation by item. Furthermore, based on this study, it will be possible to suggest a method to control the difficulty of each subject of the cognitive evaluation tool, and to prepare a standard for future research.

  • Objectives This study was aimed to find the significant features of face form according to the Taeeumin and Soyangin by analyzing the three-dimensional face information data. Also, making standard face of the Taeeumin and Soyangin was an object of this study. Methods We collected three-dimensional face data of patients aged between 20~45 years old diagnosed by a specialist of Sasang constitutional medicine. The data were collected using a 3D scanner, Morpheus 3D(Morpheus Corporation, KOREA). Extracting a face feature point total of 64, was set to 332 pieces(height, angle, ratio, etc.) of each variable between feature points. ANOVA test were used to compare the characteristics of subjects according to the Taeeumin and Soyangin. Results When not to consider gender, the Taeeumin and Soyangin were different from the 18 items(3 items in the ear, 9 items in the eye, 1 item in the nose, 1 item in the mouth, 4 items in the jaw). When to consider gender, the Taeeumin and Soyangin men were different from the 6 items(1 item in the ear, 2 items in the nose, 3 items in the face). And the Taeeumin and Soyangin women were different from 17 items(1 item in the ear, 10 items in the eye, 2 items in the nose, 1 item in the mouth, 3 items in the face). Conclusions These results show Taeeumin's face(both men and women) width of the right and left is larger than the length of the top and bottom. Compared to men of Soyangin, men of Taeeumin has greater wings of the nose. Compared to women of Soyangin, women of Taeeumin has longer length of the eye. Soyangin's face(both men and women) length of the top and bottom is larger than the width of the right and left. Compared to men of Taeeumin, men of Soyangin has smaller wings of the nose. Compared to women of Taeeumin, women of Soyangin has more stereoscopic facial features at the top and bottom of the lateral face. Also, by accumulating three-dimensional face data, this study modeled the standard facial features by Taeeumin and Soyangin. These results may be helpful in the development of Sasang constitutional diagnostics utilizing the characteristics of the facial form at later.

  • This study analyzed the size of women in their 60s, 70s and 80s in the 2014 Human Body Dimension Survey data among Size Korea's 7th Human Dimension Survey Data in 2015. This study examined the characteristics of changes in female body shape according to aging and the age range. The height item gradually decreased from the 60s and then rapidly decreased to the 80s. In the case of the circumference item, a sharp change occurred in the section from 69 to 70 years old. The reduction in hip height, waist height, and navel level waist height was not significant compared to the decrease in stature. Both width, thickness, and circumference gradually decreased with age. It can be seen that the back bends forward and the legs become thinner than the body due to the aging phenomenon with increasing age. Even for older women, the characteristics of aging differ in their 60s, 70s and 80s, so age segmentation of silver clothing should be considered.
