  • In this study, some discordance between curriculum and textbooks in usage of mathematics terms, dual meaning of some terms in the usage of those terms in textbooks, and inconsistency of defining methods of terms are discussed through some examples. Generally it can not be expected that there are any discordance between curriculum and textbooks, because textbooks are developed in the basis of curriculum. But actually, some discordance between curriculum and textbooks can be found out. Some terms are used with two different meaning, geometric figure and measure. It can be causative of troubles in teaching and learning mathematics. Terms of same kind can be expected to be consistent in the way of defining, but some examples defined inconsistently can be found out. The following four suggestions are offered as conclusions. First, textbooks must be consistent with curriculum. Second, The meaning of terms used in textbooks must be stipulated obviously. Third, terms of same kind must be defined consistently. Fourth, it is necessary to supplement a system for developing elementary mathematics textbooks. The result of this study can help develop new textbooks, and revise curriculum, and develop new curriculum.

  • The purpose of this study is to verify the effects of personalized learning platforms applied with machine learning recommendation modules that upgrade recommended algorithms by themselves through learning big data analysis on students' learning time, self-directed learning ability, mathematics achievement, and attitudes toward mathematics, and the correlation between them. According to the study, customized learning affected learning time, self-directed learning ability and mathematics attitude, while learning time affected self-directed learning ability. Self-directed learning ability has had a significant impact on the attitude of mathematics and mathematical achievements. As a result of the mediated effectiveness test, the indirect impact of customized learning on mathematics attitude and mathematics performance was significant through the medium of learning time and self-directed learning ability.

  • Several studies have reported on how and what mathematically gifted students develop superior ability or creativity in geometry and algebra. However, there are lack of studies in probability area, though there are a few trials of probability education for mathematically gifted students. Moreover, less attention has paid to the strategies to develop gifted students' creativity. This study has drawn three teaching strategies for creativity development based on literature review embedding: cognitive conflict, multiple representations, and social interaction. We designed a series of tasks via reconstructing, so called Simpson's paradox to meet these strategies. The findings showed that the gifted students made Quite a bit of improvement in creativity while participating in reflective thinking and active discussion, doing internal and external connection, translating representations, and investigating basic assumption.

  • Variation of the catches and fishing grounds, and spawning ecology of Lophius litulon caught by large staw net were investigated from following as ; L. litulon caught through the year, and the peak in catches showed on January in winter, and the lowest catches showed on August in summer. The fishing grounds of L. litulon were located in the Yellow Sea and the East China Sea. And the main fishing ground was formed in the adjacent waters of Ilhyang-cho, where catches and CPUE were more than 50 M/T, 5 kg/haul, respectively, and the range of coefficient of variation(C.V) was 0.6~0.7. The spawning season of L. litulon was on March and April, when spawning area was formed in waters between Ilhyang-Cho and Cheju-Do. The fishing grounds distribution of L. litulon was obviously different with seasonal variation. Namely, in winter, the fishing grounds were mainly formed in the western waters of Cheju-Do, and on March and April( in spawning season), the fishing grounds were densely formed in the adjacent waters of Ilhyang-Cho, and after May, the fishing grounds were widely dispersed towards in the Yellow Sea and the East China Sea with temperature upgrade.

  • Mutual savings banks have today met many difficulties because of various reasons. To overcome these difficulties, they have to change to be more customer centric and to adopt customer satisfaction management so that they can satisfy customers asking for diversified and professional service. This study aims to investigate the relationship between various dimensions of service quality and service performance such as customer satisfaction, customer trust, and repurchase intension. This study categorized service quality as interaction quality, outcome quality, and physical environment quality. Moreover, this study examined whether interest sensitivity and bank reputation had the moderating effects between service quality and service performance. The study results may provide practitioners and researchers in financial industry with some implications and guidelines for mutual savings banks' competitiveness.

  • In the field of user interface design for interactive product, it is becoming more important than ever to understand emotional quality and its characteristics. By a series of experiments on emotional quality of user interface, this paper aimed to develope a systematic approach to investigating emotional quality. First, a emotional quality framework that consists of 6 dimensions (Usefulness, Easy of Use, Aesthetics, Stimulation, Identification, and Harmony) and 18 elements was developed through two experiments that users and UI expert participated in. Second, by conducting a user survey based on the emotional quality framework, it was illustrated how various emotional qualities of interactive product can be evaluated and what effects they have on overall satisfaction of the product. Finally, this paper analyzed the relative importance of emotional quality dimensions and the contextual factors that change emotional quality, and provided basic knowledge related to the construction of emotional quality for the succeeding studies.

  • 배경 및 목적 : 한국 구개열환자에게는 된소리 자음(농음0의 구음산출의 난도가 높다는 것은 임상적으로 잘 알려져 있다. 그러므로 본 연구에서는 한국 구개열 환자에게 있어서 난도가 높은 농음의 산출 메커니즘의 기본적 요소를 규명하므로서 언어치료의 새로운 방법모색에 기여하고져 하였다. 연구방법; 비강자음에 후속된 3종의 어두 파열자음 산출시의 구개범거근의 근활동 양상의 차이를 비교검토하므로서 농음의 산출특성을 검색하고져 하였다. 관찰기록 방법은 근전도는 유구침금전극(hooked wire electrodes)을 구강내로부터 경점막적으로 유도하였다. 연구결과 : 격음과 농음의 파열자음에서 평음보다 높은 구개범거근의 근활동이 관찰되었으나 격음과 농음 사이에선 유의미적인 차이는 보이지 않았다. 결 론 : 금후의 과제로는 피험자를 늘려 재확인을 하는 일, 및 농음과 격음의 변별요소에 관해 더욱 검토할 필요가 있는 것이 시사되었다.

  • Factors causing traffic accidents are various and traffic law violations can be among them. The efforts to increase traffic law obedience rates of drivers are common in many other countries to reduce traffic accidents, and one of generally applied methods is to increase the amounts of violation fines. Expensive levels of traffic law violation fines could have drivers choose "obey the law" in their decision-making stages since they are economically better-off by following the law. In this sense, this study has developed an economic model to verify whether the current levels of the traffic violation fines of Korea are effective for drivers to choose "obey-the-law" decisions. Speed violations and traffic signal violations have been selected for the case study to verify the relationships between "expected probabilities of being-caught" and "levels of violations fines".

  • This study is trying to estimate the effect of survey of prior art on the technological performance of national R&D program, with the purpose to enhance understanding on the relationship between utilization of patent information and R&D activities. Patent and Technology Trend Research, one of the survey of prior art which gives the information about existing technology and patent trend to the project team has been carried out since 2005. In this paper, effects which Patent and Technology Trend Research has on the technological performance of national R&D projects are estimated by using multiple regression model considering input factors, characteristics of an agent and supplier of money. The result is that Patent and Technology Trend Research has positive and significant effect on the grant and application of domestic and foreign patent. This result can give an hint that the utilization of patent information make the R&D process efficient and effective.
