그래픽 계산기와 같은 공학 도구를 사용하는 수학 수업에 있어서 교사의 확신에 영향을 주는 여러 가지 요인들이 있다. 공학 도구를 사용하는 교사의 태도와 같은 내적 요인과 학교 관계자, 또는 동료교사의 지원 등과 같은 외적 요인들이 있다고 할 수 있다. 교육적 기술 지식(PTK: Pedagogical Technology Knowledge)이 교사의 테크놀로지를 사용하는데 있어서 확신을 결정짓는 중요한 요인임을 알 수 있었고, PTK의 발전은 테크놀로지에 대한 교사의 생각, 그리고 그것의 활용과 도구장착(instrumentation)으로 이루어진다고 할 수 있다. 본 연구는 예비교사와 현직교사를 포함한 19명을 대상으로 수학교육과정을 대수, 함수, 기하, 미적분, 통계 영역을 중심으로, 테크놀로지의 활용에 중점을 두어 테크놀로지를 도구장착으로 발전시키고 PTK를 확대하는 것에 중점을 둔 연구이다. 본 연구에서는 그래픽 계산기와 GSP, AutoGraph과 같은 다양한 경험을 통하여 교사들의 테크놀로지에 대한 태도를 도구장착과 도구화의 개념으로 분석하여 이것이 교사의 확신에 어떻게 영향을 미치는지를 알아보았고, 테크놀로지에 대한 전문적 지식의 발전, 교육의 질에 대한 교사들의 변화를 살펴보았다. 연구 결과 테크놀로지에 대한 교사 개인의 태도와 확신이 아주 강하다면, 부정적인 잠재적제약(constraints)와 방해요인(obstacles)은 크게 영향을 미치지 않는다는 것을 알 수 있었다. 특히 교사의 배우고자 하는 확고한 의지와 더불어 수학 학습에 있어서 테크놀로지의 가치에 대한 강한 확신은 테크놀로지의 효율적 활용에 결정적인 요소라고 할 수 있었다.

본 논문은 불확실한 상황하에서 의사결정시 의사결정의 위험도에 대한 정보의 제공과 의사결정자의 위험에 대한 태도가 의사결정에 미치는 영향에 대한 연구이다. 본 연구의 독립변수는 의사결정의 위험도에 대한 정보 제공 여부와 의사결정자의 위험 감수의 정도이다. 종속변수는 의사결정의 위험도와 의사결정 자신감을 의미한다. 본 연구는 주가지수 옵션에 대한 투자의사결정을 연구의 대상으로 하며, 연구의 진행을 위해 4가지 가설을 검증하였다. 본 연구는 연구의 방법으로 실험실 실험을 선택하였다. 실험 대상은 경영학과 학생 107명을 대상으로 하였으며, 실험의 통제 변수는 의사결정의 위험도에 대한 정보의 제공 여부이다. 실험의 의사결정자의 위험감수의 정도가 높을수록 의사결정 자신감도 높음을 알 수 있다. 그러나 의사결정의 위험도에 대한 수치적 경고 메시지는 의사결정자의 의사결정에 그다지 큰 영향을 주지 않음을 알 수 있었다. 본 연구는 실제투자자들을 대상으로 한 연구가 아니므로 실제로 위험한 상황과는 다른 모의투자라는 한계점이 있다.

This study examines the factors affecting the usage and diffusion of mobile easy payment services which is fast growing industry recently. After wide reviewing previous research about mobile payment, Some factors are identified as the factors influencing intention to use mobile easy payment services-confidence, innovativeness, mobile self-efficacy, relative advantage- through several mediating factors- perceived ease, perceived usefulness, perceived risk. Empirical study for a research model showed confidence, mobile self-efficacy and relative advantage are effective to the intention to use mobile easy payment services via perceived usefulness and perceived risk. Based on the results of the study, some practical implication for customer retention and acquisition are suggested.

The study was initiated to diagnose the problems and future direction of domestic environmentally friendly agriculture by analyzing the overall opinions of producers and consumers of environmentally friendly agriculture. The collected data were analyzed and tabulated. The research results show that relatively people of 30s${\sim}$40s are the main target groups for the marketing of environmentally friendly agricultural products. When environmentally friendly agricultural products were consumed, right information on safety of environmentally friendly agricultural products should be addressed to customers, and confidence to them has to be brought about from customers.

In this paper, we proposed Background Model Set algorithm used in the speaker verification to improve calculating confidence measure(CM) in speech recognition. CM is to display relative likelihood between recognized models and antiphone models. In previous method calculating of CM, we calculated probability and standard deviation using all phonemes in composition of antiphone models. At this process, antiphone CM brought bad recognition result. Also, recognition time increases. In order to solve this problem, we studied about method to reconstitute average and standard deviation using BMS algorithm in CM calculation.

Purpose: This paper explains how to obtain the Bayes estimates of the whole launch vehicle and of a vehicle stage, respectively, for a newly developed expendable launch vehicle. Methods: We determine the parameters of the beta prior distribution using the upper bound of the 60% Clopper-Pearson confidence interval of failure probability which is calculated from previous launch data considering the experience of the developer. Results: Probability that a launch vehicle developed from an inexperienced developer succeeds in the first launch is obtained by about one third, which is much smaller than that estimated from the previous research. Conclusion: The proposed approach provides a more conservative estimate than the previous noninformative prior, which is more reasonable especially for the initial reliability of a new vehicle which is developed by an inexperienced developer.

The purpose of this study was to investigate distribution structure system in the Italian Fashion market through the buying office and trade show. The role of trade show in Italian fashion market is facilitate interactions between the producers and buyers. Milano Unica is an example of Italian fashion trade show that successfully create the right image and attract the right audience through the differentiation policy of management strategy for the show organization. The role of buying office is to offer satisfactions for their customers through giving right informations about the product that they request to buy and confidence of quality and price.

With the development of national economy and increase of income, consumers' demand for quality and safe agricultural products have increased and perception on environmental-friendly Farming products has been sharply changing. In other words, consumers increasingly show the tendency to prefer environmental-friendly farming products for considering health and environment protection, despite higher price. The environmental-friendly farming products in Jeonnam Province is still at its early stage, accounting for 1% or so of the total products. Considerable part of environment-friendly farming products, nevertheless, difficult problem to End consumers, thus sold at relatively high prices. To the questionnaire asking their most severe difficulty is about 30.5% for sale. This suggests that strategies for consumption expansion of environment-friendly farming products, including of consumers, confidence, publicity of consumers, should be established to increase the income of environmental-friendly farmers in Jeonnam Province.

We propose a modified mid P-value method to reduce the conservativeness for the inference of conditional associations in three-way contingency tables. This improves the ordinary mfd P-value method. For $2{\times} 2${\times} K$ tables, we propose confidence intervals for an assumed common odds ratio based on inverting two separate one-sided tests using the modified mid P-value. Also, an alternative and usually even better ways of constructing intervals, based on Inverting a two-sided test, are presented. The actual probability of coverage of a 100($1-\alpha$)% confidence interval is centered about the nominal level, but the modified mid P-value approach gives actual coverage probability even closer to the nominal level than the ordinary mid P-value approach.

The purpose of this study is to investigate of differences on the viewpoint of value, job aspiration, job attitude between male and female librarians. The objects of survey are 60 librarians at National Assembly Library. The results of the survey are as follows 1) In general, librarians have advanced propensity on viewpoint of value. But female librarians appear more traditional propensity than male librarians 2) Generally, the ranking of core factors in job aspiration appears ① realise professional value, ② self confidence in occupation, ③ recognized by specialist. On this, female librarians come out ① self confidence in occupation ② realise professional value, ③ recognized by specialist. 3) Generally, librarians appear more conservative attitude than male librarians about indirect service in library
