In this study, we propose a integrated model of logistic regression, artificial neural networks, support vector machines(SVM), with case-based reasoning(CBR). To predict respondents in the direct marketing is the binary classification problem as like bankruptcy prediction, IDS, churn management and so on. To solve the binary problems, we employed logistic regression, artificial neural networks, SVM. and CBR. CBR is a problem-solving technique and shows significant promise for improving the effectiveness of complex and unstructured decision making, and we can obtain excellent results through CBR in this study. Experimental results show that the classification accuracy of integration model using CBR is superior to logistic regression, artificial neural networks and SVM. When we apply the customer response model to predict respondents in the direct marketing, we have to consider from the view point of profit/cost about the misclassification.

Purpose: This study was to identify and define the concept of a facilitator and specific attributes for providing basic data on simulation nursing education. Methods: Using Walker and Avant's (2005) criteria that identify the attributes, antecedents, and consequences of facilitators in simulation nursing education, the findings of research articles published from 2001 to 2017 were reviewed. Results: There were three aspects of the facilitator concept in simulation nursing education: (1) continuous support throughout the entire simulation process; (2) skilled progress based on clinical expertise; (3) guidance for learners to actively understand and reflect on the situation. Conclusion: This concept analysis helps us to better understand better facilitators in simulation nursing education.

The purpose of this study is to analyse prosodic characteristics of accentual phrases (AP, hereafter) produced by Chinese learners of Korean in Korean text reading. The study is restricted only to the initial APs. Subjects are students who have been studying Korean at a beginner level. The results showed that Chinese learners of Korean tended to make errors in the realization of the tonal patterns of the initial 2 syllables of the initial APs. Also they showed different F0 slopes across the initial and second syllables in the initial APs. Chinese learners of Korean, therefore, need to focus on the prosodic characteristics of the initial 2 syllables of Korean APs to realize fluent Korean intonation.

국소마취제는 치과 영역에서 임상적으로 널리 사용되어 왔으나, 국소마취제로 인한 과민반응은 매우 드물게 나타난다. 그러나 낮은 발생률에도 불구하고, 국소마취제로 인한 과민반응 증례가 보고되어 왔다. 본 증례는 충차치료를 주소로 내원한 26개월 남환에서 관찰된 과민반응으로, 리도카인 국소마취 후 하순의 부종이 발생하였다. 항히스타민제와 스테로이드의 사용으로 증상이 경감되었다.

The time-development of the wake vortices of the unsteady viscous flow past a semicircular cylinder is simulated using the vortex particle methods for direct numerical simulations(DNS). The early wake behaviour of the flow behind an impulsively started a semicircualr cylinder is evaluated for a range of Reynolds numbers between 60 and 200 with opposite body configurations respectively. The diffusion scheme based on the particle strength exchange(PSE) is used to account far the viscous effect accurately. And the vorticity generation algorithm to enforce the no-slip boundary conditions is employed. In order to redistribute particles efficiently on the distorted Lagrangian grid the particle distribution technique is adaptively revised, while maintaining the uniform resolution. The results of the simulations are compared to other experimental results.

The aim of this paper is to investigate the development of inflected words of Korean based on the analysis of 3 to 8 year-old children's spontaneous speech. For this purpose, the authors transcribe the spontaneous speech of 10 Korean children for each age and classified inflected word. The result of the analysis is as follows : $\circled1$ In the verbs simple words are occupied 62％, derivative words 18％ and complex words 20％. In the adjectives simple words are 82％, derivative words 7％ and complex words 11％. $\circled2$ The children's getting older, derivative and complex words are increased, in spite of simple words are reduced. $\circled3$ 4 year-old children get to start the ability of word formation and then since the children become 8 year-old, the children complete that ability almost all we think.

In this study, we present a comparison of multistage axial flux permanent-magnet machines (AFPMs) with different topologies for use as 100 W-class portable generating systems. Three topologies were selected, and the maximum power density and high level of efficiency were achieved by following the response surface methodology (RSM) in the design. Three-dimensional finite element analysis (FEA) was used to conduct numerical experiments to obtain the optimum design using the RSM and suggest a proper configuration of the portable generating system.

This paper presents an eddy current loss analysis of a Mechanical Fixation (MF) made of 6061 aluminum alloy, which is used for an NS type double-rotor single-stator axial flux permanent magnet machine. The prototype MF made of aluminum alloy shows good mechanical performance, but poor electro-magnetic performance, since the machine's efficiency can decrease because of eddy current loss in the MF. In order to prevent efficiency decrease, a modification of the MF structure is also introduced. Three-dimensional finite element analysis (FEA) is used for magnetic field analysis, and eddy current losses are computed. The analysis results are compared to, and verified by the test results.

This study was conducted using the literature review and survey research to analyze the operational status and effectiveness of the single-track accredited program, which has been mandatory since 2016. The research targets to achieve the purpose of the study were the nationwide engineering education accreditation system operating colleges, departments, and engineering education innovation centers. Finally, 183 copies were collected from faculty members at 69 colleges and 554 copies at the department level. As a result of the survey, the college recognized more positively about the operation of the single-track accredited program, and more than 50% of respondents said that there were difficulties due to the operation of the system. The contents required were analyzed and presented. Based on this, the engineering education accreditation system, including the single-track accredited program, suggested the direction of support at the government level and the ABEEK level to better settle down in the field of engineering colleges.

The study aimed at determining the feasibility of three portal totally Laparoscopic cryptorchidectomy in small breed dogs. Four right sided and one left sided abdomen retained testicles in five dogs weighing 2.2~8.7 kg were retrieved successfully. Pampiniform plexus and vas deference were ligated and transected with Hem-o-lock/monopolar electrocauterization (1/5), or ultrasonic scalpel (4/5) and the latter provided more easy, quick and safe hemostasis and transection. The resected testis was easily removed through a insertion site. Mean surgical time was $19.9{\pm}15.2$ minutes and when the abdominal cavity was explored again, there were no major complications. The patient recovered favorably without unwilling events. This is the case report of laparoscopic cryptorchidectomies in small breed dogs weigh less than 10 kg. Laparoscopic cryptorchidectomy could be considered as an alternative in small animal surgery.
