Installation of digital tachograph, black box, and ADAS have been enforced to commercial vehicles for preventing violent driving and accidents by the Traffic Safety Act in Korea. Nevertheless, the damage caused by road hazards has increased 1.5 times in 2016 compared to 2013. So, developing new technologies that can identify road hazard using the sensors installed in commercial vehicles are conducting by the Ministry of Land, Infrastructure and Transport. As a part of the technologies, this research analyze the error range of GPS installed in commercial vehicles that vary according to the driving speed. As a result, the average error was 9.72m at the driving speed of 100km/h, and the error was 2.1 times larger than the average error of 4.69m at the driving speed of 40km/h. The event point proper integration/separation range(m) was analyzed to be 20m with a recognition rate of 90% or more at the same point regardless of driving speed. The results of this research can be used as basic data for improving the accuracy of location-based data would be collected using commercial vehicles.

Detecting human face and facial landmarks automatically in an image is as essential step to a fully automatic face recognition system. In this paper, we present a new approach to detect automatically face and its eyes of input image with scale and rotation variations of faces by using an intensity based template matching with a single log-polar face template. In a template-based matching it is necessary to normalize the scale changes and rotations of an input image to a template ones. The log-polar mapping which simulates space-variant human visual system converts scale changes and rotations of input image into constant horizontal and cyclic vertical shifts in the output plane. Intelligent use of this property allows us to shift of the candidate log-polar faces mapped at various fixation points of an input image to be matched to a template over the log-polar plane. Thus, the proposed method eliminates the need of adapting multitemplate and multiresolution schemes, which inevitably give rise to intensive computation involved to cope with scale and rotation variations of faces. Through this scale and rotation involved to cope with scale and method can lead to detecting face and its eyes simultaneously. Experimental results on a database of 795 images show over 98% detection rate.
The purpose of this study was to investigate the performance of dental infection control. This survey was performed on 158 of the dental hygienist in certain areas. The research was performed using a self-reported questionnaire and interview method from June to July, 2014. The collected data was analyzed by PASW Statistics ver. 18.0. Guideline of infection management, infection controller, regular infection control training, Sterilization of the handpiece/per head resulted 57~74% for dental hospital. It was higher than 13~20% for dental clinics (p<0.05). Infection control guidelines and vaccination recognition of dental were more performed in dental hospital. Patient's hand hygiene performed, tooth brushing before treatment, cross infection educational experience was less than 20%, research cooperation of medical history was over 90% (p<0.05). Performing rate of the dental hospital workers were investigated higher in protective personal devices, infection control of treatment room. A correlation analysis about institutional support, infection control of dental hygienists, patients with infection control cooperation showed a positive correlation statistically significant. Infection control can be enhanced when the medical staff, the patient, the organization combined cognitive and practice. Dental hygienist is required to recognize and practice the infection control guidelines through continuing education.
This research aims to identify innovative companies' attention to the emotion and sensibility and its application by analyzing the contents of the corporate annual reports. Annual report is a good reference data because it describes not only various current products and services' annual activities and business performance but also corporate future direction. Sensibility is interpreted and used with various words internationally: various related terms such as sensibility, sense, emotion, feeling and affection are analyzed not only by the definition but also the interrelationship among them, and included for the contents analysis. To select the innovative companies, the researcher used 'Fast company' that is the economic journal and deducted the companies list via 'The world's 50 most innovative companies' in 2009 and 2014. Listed companies' 2009 and 2014 annual reports' contents were analyzed to identify the rate of the recognition and the application of sensibility to their business. Even though the quantitative result of the content analysis indicates not a strong relationship between corporate innovativeness and 'sensibility' qualitative result identifies companies are paying more attention to the 'sense' and 'feeling' during five years. In conclusion, the innovation that company pursues strategically is shifting from differentiation and the technological leadership to satisfying user experiences and the number of companies which express and measure user feeling and emotions are increasing.
The purpose of this study is to provide fundamental data supporting facilitation of a formal health education performed by school nurses as health educators. To evaluate the teacher expertise of school nurses as health educators, this study analyzed the present status of health education and the recognition of self-confidence in teaching ability of school nurses. Self addressing questionnaire were mailed out to 340 secondary school nurses in Seoul and out of them 244 nurses (71.8%) responded to the survey. Analysis of the data was made using t-test and ANOVA in SAS program. The major results are as follows : 1. The total health instruction performance rate was 84.6% (204). Regular health instruction was carried out by 66 nurses and the rest of the 155 subjects gave irregular instruction on health education. 2. Regular health education classes was offered as a part of physical education class hour by 89.4% of the respondents whereas only 10.6% of them had formal health education classes. The survey showed that irregular health education classes were mainly held in physical education class hours (70.3%) and 14.8% had opportunities for additional classes on health education. 3. The average class for regular health education was 5 hours per week but for irregular health education classes were only one hour per semester (32.9%). 4. Among the 11 categories of health education, education on drug abuse and body structure and function and physical development occupied 95.6%, 69.6% respectably while physical training, family health, social health occupied 10.8%, 12.7%. 5. Health education was given much more at public schools (88.2%) than at private schools. 6. 232 (95.0%) school nurses agreed with the necessity of formalizing health education classes and 227 (93.1%) wanted to change their status from school nurses to formal health teachers. 7. There is a tendency to change the status from school nurse to formal health teacher, and the necessity of having a formal curriculum on health education while less recognized by the older and longer-careered nurses was more recognized by those nurses with higher education. 8. The lack of administrative support (79.5%), work burden (77.9%), and lack of teaching competency (22.1%) were the greatest problems. 9. Education on drug abuse was stressed the most whereas physical training was most neglected. 10. There is a tendency that older and longer-careered school nurses thought less positively of their status, and then 98 (81.1%) school nurses acknowledged themselves as professional teachers. 11. 176 (72.5%) school nurses agreed with the necessity of continuing education : health knowledge and teaching skills for formal health teachers. 12. 179 (73.8%) school nurses had a positive attitude and undergraduate preparation and the practice of professional health teachers. 13. The school nurses had self-confidence in their teaching competence, teaching strategies and knowledge in all 11 health education areas.

National libraries have an obligation to meet the information needs of users by collecting as many various materials as possible. As legal deposit accounts for the highest percentage of the collection building methods of national libraries, they are trying to encourage the legal deposit of the publishers. However, the rate of legal deposit for the most publishers are pretty low. Therefore, in this study, the improvement plans of legal deposit system for the purpose of helping legal deposit of national libraries improve smoothly has been investigated by identifying the problems with the legal deposit system that publishers had and by suggesting the matters that should be improved based on the recognition of legal deposit by publishers. The plans for the revitalization of legal deposit for the publishers are as follows: promoting factors of legal deposit systems such as scope, deadline, compensation, fine and legal deposit libraries, simplification of legal deposit procedures, set-up of automated online system for legal deposit and strengthening of the method for promoting and educating the legal deposit.
This paper proposes the creation of an android robot head based on the facial action coding system(FACS), and the generation of emotional expressions by FACS. The term android robot refers to robots with human-like appearance. These robots have artificial skin and muscles. To make the expression of emotions, the location and number of artificial muscles had to be determined. Therefore, it was necessary to anatomically analyze the motions of the human face by FACS. In FACS, expressions are composed of action units(AUs), which work as the basis of determining the location and number of artificial muscles in the robots. The android head developed in this study had servo motors and wires, which corresponded to 30 artificial muscles. Moreover, the android head was equipped with artificial skin in order to make the facial expressions. Spherical joints and springs were used to develop micro-eyeball structures, and the arrangement of the 30 servo motors was based on the efficient design of wire routing. The developed android head had 30-DOFs and could express 13 basic emotions. The recognition rate of these basic emotional expressions was evaluated at an exhibition by spectators.

The purpose of this study is to suggest the integrated entrepreneurial competency models that reflect critical entrepreneurial competencies that entrepreneurs should have at different stages, thereby enhancing the success rate of ventures. To accomplish the purpose, this study developed the hypotheses about the positive effects of entrepreneurial competencies on business performance, and the moderating effect of learning competency to strengthen the relationship between entrepreneurial competencies and business performance. The results of this study are as follows. First, the technological functional competency of entrepreneurial teams, the resource utilization and business planning competency of entrepreneurs in the early stage of business development were found to significantly affect both non-financial and technological performance. The opportunity recognition competency has a significantly positive effect on non-financial performance. In addition, it is analyzed that learning competency significantly moderated the relationship between entrepreneurial competencies(technological functional, resource utilization) and non-financial performance. The moderating effect of learning competency between business planning competency and technological performance was also found to be significant. Second, leadership and resource acquisition competency of entrepreneurs in the late stage of ventures have significantly positive effects on both non-financial and technological performance. The strategic competency has a significantly positive effect on non-financial performance. It was also found that the moderating effect of learning competency between strategic competency and non-financial performance was significant. Finally, the results show that both non-financial and technical performance of NTBVs are significant determinants of financial performance.

Construction projects are getting more complex and larger-sized with a high economic growth rate and development of new construction technologies. In addition, interests and demands on standards of construction quality are further increasing. This trend requires more systematic and a higher level of construction quality management. While the government has strengthened the regulations for quality assurance, many quality problems have repeatedly occurred mainly due to lack of recognition for quality management and quality control systems. To address this issue, this paper aims to suggest quality management improvement scheme through analyzing 3,443 nonconforming items identified during inspection of 393 construction sites from March 2012 to October 2014. The quality management improvement scheme suggested in this research is expected to prevent quality problems and defects and thus improve construction performances.
