This study empirically examined the effects of user interface (UI) type (XR HUD vs. 2D display) and input modality (gaze+voice vs. touch) on user experience in autonomous vehicles. The purpose of the study was to verify the effectiveness of XR-based interfaces from a multidimensional perspective and to derive academic and industrial implications for next-generation UI design. A total of 40 participants aged 20–40 years were recruited, and a 2×2 factorial design (two-way ANOVA) was applied to measure usability, situation awareness, and task performance. The results indicated that the XR HUD condition significantly outperformed the 2D display across all measures, while the gaze+voice input modality showed higher efficiency and accuracy compared to touch input. Notably, the combination of XR HUD and gaze+voice input yielded the highest usability, situation awareness, and optimal task performance. These findings empirically demonstrate that XR HUD combined with multimodal input can serve as the optimal configuration for autonomous vehicle UI, highlighting its potential as a core technology that simultaneously ensures safety, immersion, and convenience. Furthermore, this study extends beyond the limitations of prior research focused only on safety or immersion by providing an integrated verification of holistic user experience. In addition, the results align with ongoing industrial efforts by global companies such as Tesla, Audi Holoride, and Volvo, thereby offering empirical evidence to inform future discussions on UI design and standardization in autonomous vehicles.

It is difficult to manage the growing deformity of forearm bone caused by hereditary osteochondromatosis in children, because deformity and discrepancy of limb length is progressive. The are many treatment methods of these problems including excisio of osteochondroma, lengthening of ulna, shortening of radius, corrective osteotomy with or without lengthening apparatus. Among many treatment methods, we tried free vascularized epiphyseal transplantation with the proximal fibular epiphysis in 3 patients of hereditary osteochondromatosis for inducement of continuous bone growth and deformity correction. The average duration of follow up was 7 years and 1 month, the shortest duration being to 4 years and 5 months and the longest 10 years and 8 months. Serial radiologic and clinical evaluation were carried out during follow up and there were satisfactory length gain, deformity correction and improvement of adjacent joint motion in 2 cases. According to our follow up evaluation, free vascularized epiphyseal transplantation is valuable procedure in forearm deformity of hereditary osteochondromatosis although it needs skillful and experienced operative technique.

This study aims to enhance the cultivation of SWㆍAI basic competencies of middle school students by forming and distributing SWㆍAI education programs for middle school students who form the basis of their lives. In addition, by planning SWㆍAI education programs in connection with the regular curriculum, it is intended to serve as a cornerstone for the public education of SWㆍAI education that will be implemented from 2025. To this end, the concept of SW and AI in middle school was first defined and a plan to link software/artificial intelligence learning factors to the regular curriculum was proposed, and based on this, SWㆍAI education programs for middle school students were prepared. Based on literature research, the understanding of artificial intelligence technology, the value of data, and the use of artificial intelligence technology in real life were set as SWㆍAI education contents, and educational programs were organized by linking them with the current middle school curriculum. All SWㆍAI education was organized in the form of practice rather than theory so that classes could be conducted centered on participants, and the purpose of the course was to cultivate the ability to use artificial intelligence technology in real life based on understanding artificial intelligence technology. 본 연구는 생의 기초를 형성하는 중학생을 대상으로 SW·AI 교육프로그램을 구성하여 이를 보급함으로써 중학생들의 SW·AI 기초역량 함양을 제고하고자 한다. 더불어 정규교육과정과의 연계에 의한 SW·AI 교육프로그램을 계획함으로써 2025년부터 시행되는 SW·AI 교육의 공교육화에 초석이 되고자 한다. 이를 위해 먼저 중학교에서의 SW·AI의 개념을 정의하고 소프트웨어/인공지능 학습요인을 정규교육과정과 연계하는 방안을 제시하여 이를 토대로 중학생을 위한SW·AI 교육프로그램을 작성하였다. 문헌 연구를 토대로 인공지능 기술의 이해, 데이터의 가치 및 실생활에서의 인공지능 기술 활용을 SW·AI 교육내용으로 설정하고, 이를 현행되고 있는 중학교 교과목의 단원별 차원과 SW·AI 교육내용과연계하여 교육프로그램을 구성하였다. 모든 SW·AI 교육은 참여자 중심으로 수업이 이루어질 수 있도록 이론보다는 실습위주의 형태로 구성되었으며 과정 이수 후에는 인공지능 기술 이해를 바탕으로 실생활에 인공지능기술을 활용할 수있는 역량을 함양하는 것을 목적으로 하였다.

Occupational cumulative traumas (CTDs) are becoming one of leading ailments in industrialized world. The degree of muscle fatigue is important parameter to understand cause of occupational cumulative trauma disorders. To quantify degree of muscle fatigue, muscle EMG activity was measured during isometric and dynamic contractions(repetitive concentric/eccentric muscle contraction) and its analyzed data, such as RMS, median frequency, and median power were compared when the muscle was fresh and exhausted. When muscle become fatigue, it was observed that median frequency decreased and median power and RMS increased However, based on overall prolonged observation, median frequency increased and median power and RMS decreased. Therefore it was concluded that shifting patterns of RMS, median frequency, and median power values can be used as parameter to evaluate degree of muscle fatigue even in dynamic muscle contraction.

Recently vascularized fibular transfer has been used in the treatment of bone tumor that are more than six centimeter in length. With refinements in microsurgical techniques and understanding of the biological and biomechanical characteristics of vascularized bone graft, the success rate of this procedure was increased. Fifteen bone tumor patients, sixteen cases seen from Apr. 1979 to Jun. 1995 were managed by means of vascularized bone graft at Kyung Hee University Hospital. Ten cases were done intercalary graft and the others were done osteoarticular graft. the ratio of male and female was 6 : 9, and mean age was 20.4 years old at operation. Mean follow up period was 5 years 4 months(range 17 months to 16 years 2 months) and mean graft length was 13.8cm. Duration for union was 5.3 months(range 3 months to 1 year) and over-all rate of union at the last follow up examination was 93.8%. Sufficient hypertrophy of grafted bone was obtained in all cases at the time of last follow up as compared to initial size of grafted bone. Several complications were found such as stress fractures, recurrence. Vascularized fibular transfer for the treatment of bone tumor is a valuable procedure in appropriately selected patients.

The management of giant cell tumor involving juxta-articular portion has always been a difficult problem. In certain some giant cell tumors with bony destruction, a wide segmental resection may be needed for preventing to recur. But a main problem is preserving of bony continuity in bony defect as well as preservation of joint function. The traditional bone grafts have high incidence in recurrence rate, delayed union, bony resorption, stress fracture despite long immobilization and stiffness of adjuscent joint. We have attemped to overcome these problems by using a microvascular technique to transfer the fibula with peroneal vascular pedicle as a living bone graft. From Apr. 1984 to Nov. 1990, we performed the reconstruction of wide bone defect after segmental resection of giant cell tumor in 4 cases, using Vascularized Fibular Graft, which occur at the distal radius in 3 cases and at the proximal tibia in 1 case. An average follow-up was 2 years 8 months, average bone defect after wide segmental resection of lesion was 11.4cm. These all cases revealed good bony union in average 6.5months, and we got the wide range of motion of adjacent joint without recurrence and serious complications.

Although the etiology of $Kienb\"{o}ck's$ disease is clearly related to avascular changes in the lunate, but the actual cause leading to this vascular impairment has remained elusive. Therefore, a great many different surgical procedures have been proposed for the correction of the multiple factors leading to lunate collapse or for the treatment of the lunatomalacia. The treatment modalities includes lunate excision, intercarpal arthrodesis, lunate implant resection arthroplasty, joint levelling operation(e.g ulnar lengthening & radial shortening), pronater quadratus pedicle graft and vascular loop graft. In the period from Jan. 1981 to Dec. 1992, we performed operative treatment in 19 cases of $Kienb\"{o}ck's$ disease. Among them, 6 cases were treated with vascular loop graft. We analysed all patients who were treated with vascular loop graft after followed up of 4 year 6 months, on an average(range from 1 year to 8 year 10 months). The results analysed are as follows, 1. All cases were stage III according to Lichtman's classification. 2. Ulnar variance was -1.5(range$-2{\sim}0$), on an average. 3. The average age of patients were 37.7years old(range 31-41). 4. Postoperatively, there were considerable restoration of range of motion and complete relief of pain in all cases, but continued decrease of grip power in one case. 5. Decreased sclerosis, loss of fragmentation and new bone formation were appeared in the last follow up film, in all cases. The vascular loop graft considered as a useful method for the treatment of the $Kienb\"{o}ck's$ disease.
