This study investigates the factors influencing nurses' turnover intentions after evaluation for certification at geriatric hospitals. Focus is centered on job stress and burnout. The study was approved by the KUIRB. Data were collected from April 1 to August 31, 2015, and analyzed using SPSS WIN 18.0 software. The participants were 205 nurses recruited from 15 long-term care hospitals in metropolitan city B in province G. The average scores for job stress, burnout, and turnover intention were 3.83, 2.92, and 3.12, respectively (range: 1-5). Nurses' turnover intention had positive relationships with job stress (r=.356, p<.001) and burnout (r=.729, p<.001). The major factor influencing turnover intention was burnout (${\beta}=.729$), which explained 53% of the intention. In conclusion, intervention programs should be developed to reduce burnout, the key influencing factor, for decreasing nurses' turnover intention.

High-lift devices have a major influence on takeoff, landing and stall performance of an aircraft. Therefore, a slotted flap design optimization process is proposed in this paper to obtain the most effective flap configuration from supported 2D flap configuration. Flap deflection, Gap and Overlap are considered as main contributors to flap lift increment. ANSYS Fluent 13.0.0$^{(R)}$ is used as aerodynamic analysis software that provides accurate solution at given flight conditions. Optimum configuration is obtained by Sequential Quadratic Programing (SQP) algorithm. Performance of the aircraft with optimized flap is estimated using Aircraft Design Synthesis Program (ADSP), the in-house performance analysis code. Obtained parameters such as takeoff, landing distance and stall speed met KAS-VLA airworthiness requirements.

In this paper, we propose a method based on multimodal biometrics system using the face and signature under ubiquitous computing environments. First, the face and signature images are obtained by PDA and then these images with user ID and name are transmitted via WLAN(Wireless LAN) to the server and finally the PDA receives verification result from the server. The multimodal biometrics recognition system consists of two parts. In client part located in PDA, user interface program executes the user registration and verification process. The server consisting of the PCA and LDA algorithm shows excellent face recognition performance and the signature recognition method based on the Kernel PCA and LDA algorithm for signature image projected to vertical and horizontal axes by grid partition method. The proposed algorithm is evaluated with several face and signature images and shows better recognition and verification results than previous unimodal biometrics recognition techniques.

With the program outcomes of 'the Accreditation of Engineering Education' in Korea, the acquisition and assessment of ethical attitudes as an engineer is emphasized these days. In this study, we surveyed and investigated the attitudes and ethical minds of college students majoring in information and communication engineering regarding their professional attitude and ethical behavior at present and in the future by assuming their hire in this industry. The average score of engineer ethics was 2.25 out of 5. Multi-variate regression found that the unethical attitudes of information and communication engineer were more distinct for students of older age, students with 'rude and insulting' attitudes, students who had not served in army, students who are not idealistic, and students who do not live with parents. The results provide educators with useful understandings related to the engineering ethics education program for college students.

The purpose of this study is to suggest the assessment method for PO6(teamwork) and PO7(communication skill), one of the most important assessment items in engineering accreditation. In this paper, we used the assessment criteria of Rubric, to empirically measure the teamwork and communication skill. Teamwork and communication skill (PO6, PO7) are the most critical social competences in modern society. Numerous studies on education showed that teamwork and communication skill can be enhanced through learning. We, therefore, need to investigate teamwork and communication skill in terms of education. However, research on the assessment method of the engineering accreditation, based on educational view is scarce. In this study, we suggest the assessment criteria of Rubric for PO6 and PO7 with the perspective of the education. We also tried to apply the developed criteria to the related subjects.

In this paper, we describe an implementation of real-time face recognition system under ubiquitous computing environments. First, face image is captured by PDA with CMOS camera and then this image with user n and name is transmitted via WLAN(Wireless LAN) to the server and finally PDA receives verification result from the server The proposed system consists of server and client parts. Server uses PCA and LDA algorithm which calculates eigenvector and eigenvalue matrices using the face images from the PDA at enrollment process. And then, it sends recognition result using Euclidean distance at verification process. Here, captured image is first compressed by the wave- let transform and sent as JPG format for real-time processing. Implemented system makes an improvement of the speed and performance by comparing Euclidean distance with previously calculated eigenvector and eignevalue matrices in the learning process.

The Ministry of Land, Infrastructure, and Transport (MOLIT) is implementing a zero-energy building (ZEB) certification to save energy for the building section and to accelerate the achievement of national greenhouse gases reduction goals in accordance with a new climate regime. In 2014, the MOLIT announced a plan for early activation of the ZEB, and in January 2016, the "Green Buildings Construction Support Act" was revised and established. In addition, the plan was established to gradually spread zero-energy buildings from the public sector in 2020 to the private sector by 2025. Therefore, this study analyzed the self-sufficiency rate of each energy factor according to the implementation of the zero energy building certification of school facilities that belong to the public sector and are included in the mandatory zero energy buildings from 2020.

This study was conducted to analyze the status radiological imaging examinations assessment in Korea medical institutions conducted in the public sector and suggest a direction for improvement. Among the assessment of medical institutions, the main assessment related to radiographic imaging examinations are the certification evaluation of medical institutions and the adequacy assessment of radiographic imaging examinations. The certification evaluation of medical institutions evaluates the image inspection operation process, provision of accurate results, and compliance with safety management procedures. In the assessment of adequacy of radiographic imaging examinations, structural indicators related to manpower and equipment, patient evaluation implementation rate, and exposure reduction programs were included. However, for safer and higher-quality radiological imaging examinations, it is necessary to increase the participation rate of medical institutions in certification evaluations. In addition, it is necessary to improve the manpower indicator, and incentive payments can be considered to induce quality improvement of medical institutions in the future. Integrated management of radiation exposure at the national level should also be carried out simultaneously.

The purpose of this study is to deduce the effective improvement plans of engineering education system and to provide the base materials by analyzing satisfaction and problems in the perception survey of stakeholders related in engineering education system including Engineering Education Accreditation System. Engineering education system improvement plans from the results of study are as follows. First, government and university should provide more financial support to the college in order to improve education environment such as laboratories and equipment. Second, in order to improve links among engineering education stakeholders, student-professor, student-faculty, and colleges should operate effective mentoring program and consultation plan. Third, according to service quality evaluation, colleges need to give rewards to distinguished faculties for their outstanding work and build up job training about services in order to enhance satisfaction of students and professors, Also, business related to Engineering Education Accreditation System should be simplified and needs to increase the number of workers exclusively responsible for this work. Forth, in order to enhance comprehension of learning outcome and outcome of Engineering Education Accreditation System, it is necessary to improve Engineering education innovation center's status, to establish active systematic promotion system and to operate engineering education evaluation expert committee such as 'Engineering education system evaluation council'. Fifth, because of the stakeholder's shortage of benefits and tiredness accumulation, the issue of effectiveness in engineering education institutions has raised controversy. Thus, engineering education institutions needs to take measure necessary. Moreover, engineering education improvements should be improved by reflecting opinions from professors, faculties and students who are practically planning, operating and participating engineering education programs.

The purpose of this study was to examine the level of stress, healthcare accreditation related job stress, adaptation, and turnover intentions, as well as to identify influencing factors of turnover intentions for operating room nurses. This study employed a descriptive correlational design. The data were collected from 163 operating room nurses using a structural questionnaire. Stress was different by age (F=5.629, p=.004), marital status (t=-2.907, p=.004), and children (t=-2.623, p=.010). Healthcare accreditation related job stress was different by age (F=11.924, p<.001), marital status (t=-4.747, p<.001), children (t=-4.434, p<.001), work experience in the OR (F=6.000, p=.003), and work reasons in the OR (t=-2.543, p=.012). Turnover intention was different by age (F=21.472, p<.001), education level (F=4.997, p<.008), religion (t=3.235, p=.001), work experience in the OR (F=13.599, p<.001), position (t=3.222, p=.002), work reasons in the OR (t=-3.001, p=.003), and a shift pattern of duties (t=-2.797, p=.006). Turnover intention was significantly correlated with stress, healthcare accreditation related job stress, and adaptation. Factors affecting turnover intention were healthcare accreditation related job stress, adaptation, and age. These factors accounted for 36.2% of turnover intention. These results suggest that relief of stress and healthcare accreditation related job stress and interventions for improving stress management.
