Purpose: The purpose of the study was to examine the career obstacle factors and career identity according to career choice type among paramedic students. Methods: A self-reported questionnaire was completed by 234 paramedic students in C area from August 25 to September 3, 2015. The questionnaire consisted of general characteristics of the subjects, career obstacle factors, career identity, and types of career choice. The data were analyzed by t test, ANOVA, post hoc $Scheff{\acute{e}}$ test, Pearson's correlation analysis, and multiple regression analysis using SPSS v. 20.0. Results: Career obstacle factors and career identity of paramedic students had significant differences on motivation of university choice, major satisfaction, and job preference. A stable type of career choice showed a significantly lower score for career obstacle factors and a higher score for career identity. Career identity had a strongly positive relationship with major satisfaction and had a negative relationship with career obstacle factors. Logistic regression analysis revealed that the main variables affecting career identity were types of career choice, motivation of university choice, major satisfaction, and career obstacle factors. The explanatory power was 58.0%. Conclusion: The development of a career integrity enhancement program can solve the career obstacle factors for paramedic students.

This study aimed to evaluate factors related to the ability of ambulatory patients with cerebral palsy (CP) to walk over vertical and horizontal obstacles. Twenty patients with spastic CP who were able to walk independently for at least 10 m with or without walking devices were recruited for the study. Participants were required to walk over small obstacles (1, 4, and 8 cm in height or width; total of 6 conditions). A 'fail' was recorded when either the lower limbs or the walking device contacted the obstacle. Linear regression analyses were used to determine the effects of age, sex, walking devices, eyeglasses, subtype (hemiplegia or diplegia), ankle foot orthoses, functional level, and score of body mass index on the ability of obstacle crossing. Fifteen participants (75%) failed to adequately clear the foot or walking device over obstacles in at least 1 condition. The chance of failure in crossing vertical obstacle was affected by the use of ankle foot orthoses, eyeglasses, gender, and CP subtype (p<.05). The failure rate crossing horizontal obstacle was affected by CP subtype. These findings suggest that rehabilitation procedures should (1) consider the clinical characteristics of patients in order to prepare them to be more independent while performing daily activities, and (2) incorporate environmental conditions that patients encounter at home and in the community.

We propose an obstacle classification method using multi-decision factors and decision sections based on Single 2D LiDAR. The existing obstacle classification method based on single 2D LiDAR has two specific advantages: accuracy and decreased calculation time. However, it was difficult to classify obstacle type, and therefore accurate path planning was not possible. To overcome this problem, a method of classifying obstacle type based on width data was proposed. However, width data was not sufficient to enable accurate obstacle classification. The proposed algorithm of this paper involves the comparison between decision factor and decision section to classify obstacle type. Decision factor and decision section was determined using width, standard deviation of distance, average normalized intensity, and standard deviation of normalized intensity data. Experiments using a real autonomous vehicle in a real environment showed that calculation time decreased in comparison with 2D LiDAR-based method, thus demonstrating the possibility of obstacle type classification using single 2D LiDAR.

Most of the construction works in domestic are not direct undertaking work, but by a contract method including subcontracting. Therefore, a general contractor for each project jointly carry out construction work with a specialty contractor for each engineering type. However, in terms of contract, this method is not a joint venture contract, but a subcontract. Accordingly, this system can cause various problems between the prime contractor and the subcontractor. Therefore, this study aims to extract and present the actual obstacle factors in terms of specialty contract company performing specialty construction work for construction project. The presented contents are expected to present the standard for the cooperation system that the prime contractor and the subcontractor can win-win.

In the past few years, data leakage of information assets has become a prominent issue. According to the National Intelligence Service in South Korea, they found 375 cases of data leakage from 2003 to 2013, especially 49 of cases have been uncovered in 2013 alone. These criminals are increasing as time passes. Thus, it constitutes a reason for establishment and operation of ISMS (Information Security Management System) even for private enterprises. But to be ISMS certified, there are many exposed or unexposed barriers, moreover, sufficient amount of studies has not been conducted on the barriers of ISMS Certification. In this study, we analyse empirically through exploratory factor analysis (EFA) to find the obstacle factors of ISMS Certification. The result shows that there are six obstacle factors in ISMS Certification; Auditing difficulty and period, Consulting firm related, Certification precedence case and consulting qualification, Internal factor, CA reliability and auditing cost, Certification benefit.
