This study developed the learning ability-based smart education program. The effectiveness of the developed materials was investigated using the quantitative-qualitative mixed method, and the process and results of the investigation are as follows. The quantitative investigation was conducted using the non-equivalent pretest-posttest design, in which the smart education method was applied to the experimental group, while the conventional education method was applied to the control group to analyze students' creative problem-solving potential, task concentration, and the variables required for the learning activity. The results showed significantly higher performance in the experimental group over the control group. Regarding data collection in the qualitative investigation, an analysis of the class from the instructor and class consultation logs from the class analyst were collected; the comments on the experience of each class period were collected from students. The results of the analysis of the data suggest that the perception of smart education improved for the instructor, class analyst, and learners as the course progressed.

우리나라는 2002년부터 제도적 장치 하에 영재교육을 실시하였고, 영재교육은 양적으로 성장하여 왔다. 그러나 양적성장에 비해 질적 성장이 미비하여 영재교육 내실화가 필요하다. 이 연구의 목적은 러시아의 최근 교육동향을 알아보고, 과학영재교육사례를 분석하는 것이다. 이 연구를 위해 현재 러시아 영재교육 현장에서 활동하는 3명의 과학영재학교장, 1명의 교육심리학자, 1명의 교육행정가와 심층면담을 실시하여 데이터를 수집하였고. 수집된 데이터를 체계적 접근에 따라 분석하였다. 러시아의 과학영재교육은 교육을 통해 영재성이 성장할 수 있다는 가정 하에 학교에서 학생들의 영재성이 최대한 발현될 수 있는 교육을 실시한다. 때문에 학교의 형태 또한 더욱 세분화된 과학영재 학교가 운영되고 있다. 우리나라에서는 영재교육 초기는 학업성취가 높은 일부 학생을 위한 특수교육으로서의 영재교육이 실시되고 있었지만, 이제 영재의 창의성을 발현하고 잠재적 영재성을 깨울 수 있는 다양한 교육방법을 개척하기 위해 노력해야 할 것이다.

Purpose: This study describes the ecological variables effect on child abuse potential and the results from a prevention program for parents with disabled children aiming at decreasing child abuse potential. Method: Data was collected from 30 parents with disabled preschoolers attending an early education center in a community. The program consisted of handouts, small group lectures, support group meetings on understanding the disabled child-parents relationship, communication skill improvement, non-punitive discipline techniques, and influences of child abuse. A non equivalent pre-post test design was employed. Result: Ecological variables, and parenting self-efficacy, had a significant effect on child abuse potential in parents with a disabled child. By regression parenting self-efficacy showed(27.1 %) child abuse potential. Both parenting self-efficacy and beliefs in corporal punishment directly related to (52.0%) child abuse potential in parents. The program was effective inbringing some positive changes on pareting self-efficacy beliefs in corporal punishment, and child abuse potential toward disabled children. However, marital discord was not significantly effected. Conclusion: Child abuse prevention programs should decrease thechild abuse potential in parents. Thus I recommend a child abuse prevention program development; for parents with disabled adolescents, and teachers in disabled child education.

Dairy processing experience tourism, that combines production, processing, and services, can be a good alternative to increase added value in Mongolian livestock industry. In addition, in order to successfully pursue this, it is necessary to first identify consumers' potential demand for the experience tourism and the factors affecting demand. Accordingly, this study estimated consumers' potential demand for dairy processing experience tourism using data from 758 people obtained through an online survey targeting Ulaanbaatar residents. As a result of the estimation, it was found that the variables that affect potential demand are the experience fees, average monthly household income, gender, age, arol consumption, and education level. The potential demand for dairy processing experience tourism was measured by multiplying the population of Ulaanbaatar by the estimated probability of accepting the experience tourism, and the total revenue was maximum at 32.303 million Tuk when the experience fee was 50,000 Tuk. The implications based on the analysis results are that, in order to promote participation in the experience tourism, it is necessary to promote it primarily to people with high average monthly household income, high level of education, younger age groups, and male. It can be said that preference is high and sufficient potential demand exists, but it is suggested that appropriate setting of experience fees is important.

In this study, we introduce a canonical correlation analysis method to accurately assess the tunnel damage potential of ground motion. The proposed method can retain information relating to the initial variables. A total of 100 ground motion records are used as seismic inputs to analyze the dynamic response of three different profiles of tunnels under deep and shallow burial conditions. Nine commonly used ground motion parameters were selected to form the canonical variables of ground motion parameters (GMP_CCA). Five structural dynamic response parameters were selected to form canonical variables of structural dynamic response parameters (DRP_CCA). Canonical correlation analysis is used to maximize the correlation coefficients between GMP_CCA and DRP_CCA to obtain multivariate ground motion parameters that can be used to comprehensively assess the tunnel damage potential. The results indicate that the multivariate ground motion parameters used in this study exhibit good stability, making them suitable for evaluating the tunnel damage potential induced by ground motion. Among the nine selected ground motion parameters, peck ground acceleration (PGA), peck ground velocity (PGV), root-mean-square acceleration (RMSA), and spectral acceleration (Sa) have the highest contribution rates to GMP_CCA and DRP_CCA and the highest importance in assessing the tunnel damage potential. In contrast to univariate ground motion parameters, multivariate ground motion parameters exhibit a higher correlation with tunnel dynamic response parameters and enable accurate assessment of tunnel damage potential.

A continuous, explicit drain-current equation for short-channel double-gate (DG) MOSFETs has been derived based on the explicit surface potential equation. The model is physically derived from Poisson's equation in each region of operation and adopted in the unified regional approach. The proposed model has been verified with numerical solutions, physically scalable with channel length and gate/oxide materials as well as oxide/channel thicknesses.

In this paper, we consider an interaction energy with attractive-repulsive potential. We survey recent results on the structure of global minimizers for the mildly repulsive interaction energy. We introduce a theorem which is important to the proof of the above results, and give a detailed proof of the theorem.

This paper was studied on the effect of the specific resistance of water on corrosion characteristics of STS 304 for gas boiler. The electrochemical polarization test of STS 304 for gas boiler was carried out. And the polarization resistance, uniform corrosion, corrosion behavior by impressed potential and corrosion sensitivity of STS 304 with specific resistance were considered. The main results are as following: 1) With being low the specific resistance of water, the polarization resistance and corrosion potential of STS 304 decreases, while corrosion current density increases. 2) Under constant impressed potential, the corrosion sensitivity of STS 304 is large with being low the specific resistance due to synergy effect of Cl ion.

This paper presents a general analytical method for predicting the magnetic fields of different Halbach magnet arrays with or without back iron mounted on slotless permanent magnet (PM) linear machines. By using Fourier decomposition, the magnetization components of four typical Halbach magnet arrays are determined. By applying special synthetic boundary conditions on the PM surfaces, the expressions of their magnetic field distributions are derived based on the magnetic scalar potential (MSP), which are simpler than those based on the magnetic vector potential (MVP). The correctness of the method is validated by finite element analysis. The harmonics of airgap flux density waveforms of these Halbach magnet arrays with or without back iron are also compared and optimized.
