Objective: There is a lack of studies using the 3D-2D image registration techniques on the mechanism of a shoulder injury for ice hockey players. This study aimed to analyze in vivo 3D glenohumeral joint arthrokinematics in collegiate ice hockey athletes and compare shoulder scaption with or without a hockey stick using the 3D-2D image registration technique. Method: We recruited 12 male elite ice hockey players (age, 19.88 ± 0.65 years). For arthrokinematic analysis of the common shoulder abduction movements of the injury pathogenesis of ice hockey players, participants abducted their dominant arm along the scapular plane and then grabbed a stick using the same motion under C-arm fluoroscopy with 16 frames per second. Computed tomography (CT) scans of the shoulder complex were obtained with a 0.6-mm slice pitch. Data from the humerus translation distances, scapula upward rotation, anterior-posterior tilt, internal to external rotation angles, and scapulohumeral rhythm (SHR) ratio on glenohumeral (GH) joint kinematics were outputted using a MATLAB customized code. Results: The humeral translation in the stick hand compared to the bare hand moved more anterior and more superior until the abduction angle reached 40°. When the GH joint in the stick hand was at the maximal abduction of the scapula, the scapula was externally rotated 2~5° relative to 0°. The SHR ratio relative to the abduction along the scapular plane at 40° indicated a statistically significant difference between the two groups (p < 0.05). Conclusion: With arm loading with the stick, the humeral and scapular kinematics showed a significant correlation in the initial section of the SHR. Although these correlations might be difficult in clinical settings, ice hockey athletes can lead to the movement difference of the scapulohumeral joints with inherent instability.

This study is to develop a diagnostic model for the effective introduction of smart factories in the manufacturing industry, to diagnose SMEs that have difficulties in building their own smart factory compared to large enterprise, to identify the current level and to present directions for implementation. IT, AT, and OT experts diagnosed 18 SMEs using the "Smart Factory Capacity Diagnosis Tool" developed for smart factory level assessment of companies. They analyzed the results and assessed the level by smart factory diagnosis categories. Companies' smart factory diagnostic mean score is 322 out of 1000 points, between 1 level (check) and 2 level (monitoring). According to diagnosis category, Factory Field Basic, R&D, Production/Logistics/Quality Control, Supply Chain Management and Reference Information Standardization are high but Strategy, Facility Automation, Equipment Control, Data/Information System and Effect Analysis are low. There was little difference in smart factory level depending on whether IT system was built or not. Also, Companies with large sales amount were not necessarily advantageous to smart factories. This study will help SMEs who are interested in smart factory. In order to build smart factory, it is necessary to analyze the market trends, SW/ICT and establish a smart factory strategy suitable for the company considering the characteristics of industry and business environment.

Contemporary University students are considered the Z generation who were born after 1995. They are more tech savvy than millennials. To target the generation, traditional class management platforms have evolved to smart LMS that is more customized and accessible for smart devices. Global level information search and collaboration can also be implemented using such smart LMS. However, switching from one LMS to another LMS requires great effort from teachers and support from staffs. This study measured the learners' perception of the system when they were exposed to a new smart-LMS. Blackboard Learn Ultra was used for 15 weeks and at the end of the semester, a questionnaire was administered to the students of these classes. Results indicated that experience with previous LMS discouraged students from adopting Blackboard Learn. Result of TAM modeling indicated that perceived usefulness, compared to perceived ease of use and attitude, was an effective aspect to bring positive acceptance of the system. A qualitative approach and network analysis were also conducted based on students' responses. Both positive and negative responses were detected. Inconvenience due to mechanical aspects was mentioned. Dissatisfaction compared to previous local LMS use was also mentioned. Mobile application and communication effectiveness were positive aspects. Revised course development and promoting how useful the system may help enhance the acceptance of the new system.

Hospice is the wholistic caring service for terminally ill patient and his family so that he can live in dignity and maintain the quality of life until he passes away peacefully. The purpose of this study is to compare the development of hospice movement in UK, USA, Japan and Korea, to analyze space configuration characteristics of facilities built between 1980-2009 through case study. The result is as follows. First, The modern hospice started in England and it has spread around the world rapidly. In Korea, hospice service was introduced even prior to US and Japan and developed in spite of poor medical environment. The application of health insurance subsidies were late compared to other countries, but the hospice and palliative care system was quickly set on the basis of precedent cases. Second, the number of hospital beds per facility is decreasing, and it has been divided into smaller clusters for the residential atmosphere. The controversy between private rooms and multi-patient room is still ongoing, and increasing facilities without in-patient service. Rather than establishing uniform and absolute regulations, it is necessary to design a flexible space which can cope with various situations such as patients' needs, service changes, and manpower status. Third, the spaces for family members and friends to stay in both private rooms and communal spaces are increasing. Forth, Facilities for patients with different needs, such as children and adolescents and AIDS patients, have been developed in UK and USA. Further research on of patients' diverse needs and customized environmental support is necessary.

This study aims to provide implications for the realization of the SDG goal for higher education through a comparative analysis of the UK and Australia's inclusive higher education policies. The cases of the UK and Australia were chosen for analysis since both countries have developed various policies to strengthen the inclusiveness of higher education since the early 2000s. The implications for the Korean government are as follows. First, it should approach the concept of underprivileged students by applying various categories such as 'race, region, and etc.,' not just for a category of income level. Second, it should enhance higher education opportunities for underprivileged students not only by expanding admission opportunities for them, but also by assisting them to adapt to college life and develop a student career. Third, it should provide underprivileged students with the customized support in consideration of their characteristics and merits. Finally, it should develop the "Inclusive Higher Education Project" which would help them complete higher education courses through regional partnerships.
