This study was implemented for the purpose of analyzing the Job Competency level of accredited and non-accredited program's graduates. And we were seeking way to manage realistic and effective way of Accreditation of Engineering education. In order to achieve the purpose of this study, survey and FGI were done. The study was: accredited program's graduates thought more positively than non-accredited program's graduates, and graduates felt that 11 Job Competencies Level of Work Performance were lower than the needs of job performance. The conclusions of this study were summarized as follows: First, between accredited and non-accredited program's graduates, we could see significant recognition difference about the perception of the needs of job performance. This was because Design curriculum were reinforced and accredited program's graduates had attended design program at accredited program. Second, accredited program's graduates felt higher than non-accredited program's graduates about the perception of level of work performance. This was because the efforts for curriculum reorganizing and teaching methods improvement were done. Third, we could not find significant recognition difference about the perception of the needs for job performance and work level. That was because accredited and non-accredited program were not dealed seperately. The conclusions of this study are summarized as follows: First, The efforts for analyzing job competence of industry and reflecting the program curriculum are needed on the accredited program for engineering education. Second, Government should make the incentive policy about the companies which give some merits to the accreditation graduates, and monitor constantly their real working. Third, in order that the accreditation results can be trustful on staff recruiting or school choosing, accreditation should make outcome-based-evaluation which guarantees competence of graduates.

Purpose: The purpose of this study was to develop and to apply the NANDA, NOC, and NIC (NNN) linkages into a computerized nursing process program using the classification systems of nursing diagnoses, nursing outcomes and nursing interventions. Method: The program was developed with planning, analysis, design and performance stages. The program was applied to 117 patients who were admitted to orthopedic surgery nursing units from January to February, 2004. Results: Thirty-five of fifty-three nursing diagnoses were identified. Five nursing diagnoses in order of frequency were: Acute pain $(28.4\%)$, Impaired physical mobility $(15.6\%)$, Impaired walking $(8.7\%)$, Chronic pain $(5.5\%)$ and Risk for disuse syndrome $(5.0\%)$. The nursing outcomes of the 'Acute pain' nursing diagnosis tended to have higher frequencies (cumulative) in order of Pain management $(95.2\%)$, Comfort level $(35.5\%)$ and Pain level $(17.7\%)$. The nursing interventions of the 'Acute pain' nursing diagnosis tended to have higher frequencies (cumulative) in order of Pain management $(71.0\%)$, Splinting $(24.2\%)$ and Analgesic administration $(17.7\%)$. In comparison of outcome indicator scores between before and after the intervention according to the 61 nursing outcomes, the mean scores of 52 outcome indicators after the intervention were significantly higher than before the intervention. Conclusion: It is expected that this program will help nurses perform their nursing processes more efficiently.

In this paper, a new displacement field based on quasi-3D hybrid-type higher order shear deformation theory is developed to analyze the static and dynamic response of exponential (E), power-law (P) and sigmoïd (S) functionally graded beams. Novelty of this theory is that involve just three unknowns with including stretching effect, as opposed to four or even greater numbers in other shear and normal deformation theories. It also accounts for a parabolic distribution of the transverse shear stresses across the thickness, and satisfies the zero traction boundary conditions at beams surfaces without introducing a shear correction factor. The beam governing equations and boundary conditions are determined by employing the Hamilton's principle. Navier-type analytical solutions of bending and free vibration analysis are provided for simply supported beams subjected to uniform distribution loads. The effect of the sigmoid, exponent and power-law volume fraction, the thickness stretching and the material length scale parameter on the deflection, stresses and natural frequencies are discussed in tabular and graphical forms. The obtained results are compared with previously published results to verify the performance of this theory. It was clearly shown that this theory is not only accurate and efficient but almost comparable to other higher order shear deformation theories that contain more number of unknowns.

Wavefront aberrations of a laser beam that was reflected from an off-axis parabolic (OAP) mirror were measured to evaluate the optical performance of the OAP mirror. For a diamond turned OAP mirror, the root-mean-square (rms) value of higher-order aberrations was only $0.03{\mu}m$ for the laser beam size of about 34 mm. The other OAP mirror which was polished at a domestic company had the rms value of higher-order aberrations of $2.07{\mu}m$ for the same beam size. Although the diamond turned OAP mirror was well fabricated to have a small amount of aberrations, the aberrations were induced by the misalignment of the OAP mirror. Especially, 0 degree astigmatism increased with the sensitivity of $0.372{\mu}m/mrad$ when the OAP mirror was tilted in the tangential plane, which agreed well with the calculated results using a commercial ray tracing software.

The purpose of this study is to analyze the current status of augmented reality picture books, which have been steadily developed since 2010, as a genre of electronic picture books, and to reveal how children's immersion in augmented reality picture books differs from paper picture books. To this end, 30 augmented reality picture books on the market were analyzed according to genre, life theme, implementation method, and augmented reality scene ratio. As a result of the study, it was found that the genre of picture books was in the order of information fairy tales, daily fairy tales, and historical fairy tales, and there were no traditional or fantasy fairy tales. Animals and plants accounted for about half of the life topics, and in some cases, there were only a few or no other life topics. In the augmented reality implementation scene, it consisted of only one page in the early days, but all pages are now possible to implement augmented reality due to technology development, production cost reduction, and improved hardware performance of smartphones. It was found that the augmented reality implementation method used CD-ROM in the early days, but gradually became possible to implement using only mobile phones and tablets that were easy for readers to access. In addition, after presenting four picture books to eight 5-year-old infants, the immersion time was measured and the immersion behavior was observed. As a result, augmented reality picture books showed higher immersion[immersion time, immersion behavior] than paper picture books, but compared by literature genre, life fairy tales were higher in paper picture books and natural fairy tales in augmented reality picture books. It was higher when presenting augmented reality picture books after presenting paper picture books according to the order of presentation of picture book types. The results of this study suggest that more diverse life topics and augmented reality picture books in the genre of children's literature should be developed to increase the utilization of augmented reality picture books. In addition, considering that there are differences in immersion between types, literary genres, and reading experience [presentation order], it is expected to increase the educational effect by using picture books complementarily.

In order to understand the effect of duck hepatitis B virus (DHBV) on the economic performance of ducks, Three groups (DHBV congenitally infected, experimentally infected and DHBV negative) Brown Tsaiya ducks (Anas platyrhyncha) were used for experimental animals. Artificial insemination and pedigree hatching were applied in the propagation of ducklings, and the efficiency of vertical transmission and experimental infection was analyzed through the detection of DHBV DNA in the sera of 8-week-old offspring. The observation of the records of the first year indicated that the persistent infection had no significant effects on the performance of ducks, except the egg number of survival ducks up to 40 week of age. Thus DHBV infection did not appear to give ill effects to the economic performance of ducks in first laying year. A higher infection rate (85.3%) was obtained in congenital transmission than that (75.5%) of experimental infection. Both modes of infection did not reach 100% infectious rate, although some ducks developed transient viraemia in a tracing of DHBV DNA for 24 weeks to 11 challenged ducklings.

Purpose: The purpose of this study is to compare and analyze the tokenizer in natural language processing for customer satisfaction in sentiment analysis. Methods: In this study, a supervised learning-based tokenizer Mecab-Ko and an unsupervised learning-based tokenizer SentencePiece were used for comparison. Three algorithms: Naïve Bayes, k-Nearest Neighbor, and Decision Tree were selected to compare the performance of each tokenizer. For performance comparison, three metrics: accuracy, precision, and recall were used in the study. Results: The results of this study are as follows; Through performance evaluation and verification, it was confirmed that SentencePiece shows better classification performance than Mecab-Ko. In order to confirm the robustness of the derived results, independent t-tests were conducted on the evaluation results for the two types of the tokenizer. As a result of the study, it was confirmed that the classification performance of the SentencePiece tokenizer was high in the k-Nearest Neighbor and Decision Tree algorithms. In addition, the Decision Tree showed slightly higher accuracy among the three classification algorithms. Conclusion: The SentencePiece tokenizer can be used to classify and interpret customer sentiment based on online reviews in Korean more accurately. In addition, it seems that it is possible to give a specific meaning to a short word or a jargon, which is often used by users when evaluating products but is not defined in advance.

Purpose: To study aimed to examine the impact of the Nursing and Care=giving Integrated Service on nursing work performance, nurse' job satisfaction, and patient safety. Methods: A total of 66 nurses were selected as participants, comprising 30 nurses working in Nursing and Care=giving Integrated Service hospital ward, and 33 nurses working in a general hospital ward with a similar patient and disease group and distributed moderately. For data analysis, t-tests, ANOVA, and $X^2$ tests were conducted. Results: Nursing work performance in the Nursing and Care=giving Integrated Service ward was higher than that in the general hospital ward, but this difference was not statistically significant. Conversely, job satisfaction was lower among nurses in the Nursing and Care=giving Integrated Service ward, although again the difference was not significant. However, the Nursing and Care=giving Integrated Service ward had a significantly lower rate of safety-related accidents in patients compared to the general hospital ward. Conclusion: In order to expand and improve patient safety and other aspects of the Nursing and Care=giving Integrated Service, there is a need to establish a mediation strategy for increasing nurses' work performance and job satisfaction.

Rare-earth barium copper oxide (REBCO) coated conductor (CC) tapes have already been commercialized but still possess some issues in terms of manufacturing cost, anisotropic in-field performance, $I_c$ response to mechanical loads such as delamination, homogeneity of current transport property, and production length. Development on improving its performance properties to meet the needs in practical device applications is underway and simplification of the tape's architecture and manufacturing process are also being considered to enhance the performance-cost ratio. As compared to low temperature superconductors (LTS), high temperature superconductor (HTS) REBCO CC tapes provide a much wider range of operating temperature and a higher critical current density at 4.2 K making it more attractive in magnet and coil applications. The superior properties of the REBCO CC tapes under magnetic field have led to the development of superconducting magnets capable of producing field way above 23.5 T. In order to achieve its optimum performance, the electromechanical properties under different deformation modes and magnetic field should be evaluated for practical device design. This paper gives an overview of the effects of mechanical stress/strain on $I_c$ in HTS CC tapes due to uniaxial tension, bending deformation, transverse load, and including the electrical performance of a CC tape joint which were performed by our group at ANU in the last decade.
