Myeong Hun Beak, Jin Gyo Jeong, Young Jae Kim, Kwa | JNCIST 9(1) 1-9

Abstract : Scoliosis is one of most common spine diseases. The measurement of Cobb angle is gold standard of the diagnosis of scoliosis. However, the reliability and accuracy of the cobb angle measurement has room for improvement. In this study, a model was trained for thoracic and lumbar vertebra segmentation based on Convolution Neural Networks. The data consisted of 252 data and 10-fold cross-validation was performed. Also, the measurement of cobb angle was performed using the deep learning-based approach and it was compared with that of manual measurement. As a result, the average sensitivity of the dataset was 0.927, the specificity was 0.999, the accuracy was 0.998, and the Dice’s similarity coefficient was 0.927. There is no statistical difference in cobb angle measured by the deep learning-based approach and the manual measurement. Also, the intraclass correlation coefficient between them was 0.973. Therefore, it is expected that vertebra segmentation using deep learning will be useful for the measurement of cobb angle.

A Study of Technology and Application Plan on Context Detection for Customized Disaster

Jeong-ho Lee, Dong-san Jun | JNCIST 9(1) 11-19

Abstract : Recent climate change and urban complication have dramatically increased the potential for natural andsocial disasters. As a result, as the interest in disaster response is focused, the goal of the disaster responseis to quickly recognize the disaster situation and apply a response manual for each disaster situation tominimize human and material damage. However, since the experience of the disaster management personnelis forced to accumulate while experiencing a disaster, there is a limit to recognizing the situation in theearly stage and performing an appropriate disaster response procedure. In this paper, we propose a deeplearning-based image recognition method for edge-based disaster situation awareness. According to thismethod, it is possible for disaster management personnel to quickly respond to a disaster by minimizingdisaster damage by real-time processing and analyzing on-site images to detect the occurrence of thedisaster and predict the situation of the risk and uncertainty.

Auditory user interface design guidelines for control transitions in the conditional self-driving phase

Kiechan Namkung, Chaemoon Yoo, Hyemi Jeon, Younghw | JNCIST 9(1) 49-59

Abstract : Among the phases of self-driving, the transition of control over drivingvehicles to drivers occurs in the conditional self-driving phase. Therefore, designing appropriate user interfaces to perform safe control transitions is crucial. However, most previous studies have focused on evaluating the performance and safety of self-driving systems. In the conditional self-driving phase, no regulations that can force drivers to control their eyes currently exist, meaning the control transition, which relies solely on the visual-centric user interfaces used in traditional driving environments, is not safe. Therefore, in this study, we developed guidelines for an auditory user interface design to ensure safe control transition. We derived these guidelines by applying a user experience design methodology and defining important principles in the appropriate combination of voice and sound feedback.

Seung-won Lee, Won-kyeong Lee, Jeong-ho Lee | JNCIST 9(1) 85-93

Abstract : In recent years, it has become increasingly difficult to predict whenhow a disaster will occur. The disaster response system can be said to be a cooperative structure of government-enterprise-citizen society based on the type of disaster and on-the-spot situation to reduce risk factors and minimize the spread of damages caused by a disaster. In order to operate an effective cooperative structure, a disaster response plan and a cooperative system plan are needed to define roles and responsibilities between governments, public institutions, NGOs, and private organizations in the event of a disaster. In this paper, for effective disaster response, the nature and characteristics of the disaster response organization and the main tasks of the disaster management support organization are summarized by disaster type. In addition, by establishing a unified command system for quick application to disaster response tasks and establishing the basic system of 13 collaboration functions for each disaster type for smooth collaboration and information sharing, the schematic content of the collaboration response system according to the size and complexity of disasters.

Ye Rang Park, Young Jae Kim, Kwang Gi Kim, Sheen-W | JNCIST 9(1) 95-102

Abstract : Shoulder-related disorders include joint and labial injuries, shoulder impingement syndrome, habitual shoulder dislocation and slab lesions. According to health insurance statistics, the number of patients treated with these shoulder lesions is increasing every year. MRI (Magnetic Resonance Imaging) is a representative method of diagnosing such shoulder-related diseases. In this paper, we will use U-net, a convolution neural network algorithm, to automatically segment humeral heads, joints in MR images to help doctors diagnose related diseases more quickly. A total of 2251 MR images of 81 patients were collected and used as training set and test set. As a result of evaluation of U-net trained scapular segmentation model validated by chapter 427 data, sensitivity of 89.32%, specificity of 99.78%, accuracy of 99.44%, and die coefficient of 92.02%. In the future, image processing techniques will solve the ambiguity of the scapular border and collect additional data to fully train the joints and regions, which will provide a higher level of accuracy and help the diagnosis for doctors.
