The purpose of this study is to examine and compare effects of psychological factors on market mavenism and fashion leadership in order to determine the differences of two influential groups in the marketplace. The data were collected from 20's-50's consumers through an online survey institute and a total of 857 questionnaires were analyzed. Demographic variables (gender, age, and income level) were entered into the regression model 1 as independent variables, and 6 factors of consumer self-confidence, clothing involvement, status consumption, and price consciousness were entered into the regression model 2. In the regression model 1, gender (female) alone was significant in explaining market mavenism, while the income level had a positive relationship with fashion leadership. In the regression model 2, information acquisition, social outcome, persuasion knowledge among consumer self-confidence, and status consumption were significant predictors of market mavenism. On the other hand, personal outcome, social outcome, persuasion knowledge, clothing involvement, and status consumption had an effect on the fashion leadership. When comparing magnitudes of effects in predicting market mavenism and fashion leadership, social outcome and status consumption showed to have stronger impacts on fashion leadership than on market mavenism. Psychological factors showed to be more powerful in predicting market mavenism or fashion leadership, as compared to demographic variables.

This study was performed 10 develop the accelerated life test method using Weibull-IPL(Inverse Power Law) model for mechanical components. Weibull-IPL model is concerned with determining the assurance life with confidence level and the accelerated life test time From the relation of weibull distribution factors and confidence limit, the testing times on the no number of failure acceptance criteria arc determined. The mechanical components generally represent wear and fatigue characteristics as a failure mode. IPL based on the cumulative damage theory is applied effectively the mechanical components to reduce the testing time and to achieve the accelerating test conditions. As the actual application example, accelerated life test method of agricultural tractor transmission was described. Life distribution of agricultural tractor transmission was supposed to follow Weibull distribution and life test time was calculated under the conditions of average life (MTBF) 3,000 hours and 90% confidence level for one test sample. According to IPL, because test time call be shorten in case increase test load test time could be reduced by 482 hours when we put the load 1.1 times of rated load than 0.73 times of rated load that is equivalent load calculated by load spectrum of the agricultural tractor. This time, acceleration coefficient was 11.7.

Bakery nutrition labeling has been implemented in the company, but most consumers have no idea about it due to lack of promotion of the product nutrition labeling information or do not have a big interest in it. As a result, various studies based on the forecast about changes in consumption patterns of the bakery market due to nutrition labeling information are needed. Especially nowadays, when buying bakery products the involvement of consumers in health and nutrition is growing. So, we need to understand that nutrition labeling information makes any causal relationship between consumer attitude and confidence, purchasing behavior in bakery products. It can be said to be a very important research. For that reason, I think this research will help to settle and activate the nutrition labeling information system for the rational purchasing decisions of consumers in the bakery market. In addition, this research could be a base material for various marketing strategies.

본 연구는 미국의 경영정보전공 학생집단과 일반경영전공 학생집단의 창업 자신감에 대하여 서로 어떻게 다른가를 비교 분석했다. 본 연구에 필요한 자료는 미국의 네브라스카 대학교의 경영정보전공 학생들과 일반경영전공 학생들로부터 설문지를 통하여 직접 수집했다. 자료분석은 ANOVA, t-test 그리고 다중회귀분석을 사용했다. 분석결과는 MIS전공 학생들이 일반경영전공학생들 보다 창업에 대한 자신감이 훨씬 더 높았다. 본 연구 결과는 창업에 대한 자신감이 부여되기 위해서는 경영정보교육이 필요하다는 것을 시사하고 있다.

In this paper, we present several confidence measures (CM) for speech recognition systems to evaluate the reliability of recognition results. We propose heuristic CMs such as mean log-likelihood score, N-best word log-likelihood ratio, likelihood sequence fluctuation and likelihood ratio testing(LRT)-based CMs using several types of anti-models. Furthermore, we propose new algorithms to add weighting terms on phone-level log-likelihood ratio to merge word-level log-likelihood ratios. These weighting terms are computed from the distance between acoustic models and knowledge-based phoneme classifications. LRT-based CMs show better performance than heuristic CMs excessively, and LRT-based CMs using phonetic information show that the relative reduction in equal error rate ranges between $8{\sim}13%$ compared to the baseline LRT-based CMs. We use the support vector machine to fuse several CMs and improve the performance of utterance verification. From our experiments, we know that selection of CMs with low correlation is more effective than CMs with high correlation.

In applications using a linear regression model with nested error structure, one might be interested in making inferences concerning variance components. This article proposes approximate confidence intervals on the variance component of the primary level in a simple linear regression model with an unbalanced nested error structure. The intervals are compared using computer simulation and recommendations are provided for selecting an appropriate interval.

For all pairwise comparisons of treatments, Bayesian simultaneous confidence intervals are proposed and studied. First Bayesian solutions are obtained for a fixed prior, and then prior parameters are estimated by a parametric empirical Bayesian method. The nominal confidence level is shown to be controlled asymptotically. An extension to the unbalanced design is also considered.

A parametric empirical Bayes procedure is proposed and studied to compare treatments simultaneously with the best. Minimum Bayes risk lower bounds are derived for an additive loss function, and their relationship with Bayesian simultaneous confidence lower bounds is given. For the proposed empirical Bayes procedure, the nominal confidence level both in Bayesian sense and in frequentist's sense is shown to be controlled asymptotically. For practical implementation, a measure of significance similar to f-value is suggested with an illustrative example.

본 연구는 일·생활 균형문화 확산 및 맞벌이 부부의 증가 등으로 변화된 성별에 따른 일·생활 균형 인식수준 차이분석과 일·생활 균형이 부모 자신감에 미치는 영향을 살펴보고자 하였다. 더불어 일·생활 균형이 부모 자신감에 미치는 영향관계에서 경력관리의 조절효과를 살펴보고자 하였다. SPSS 18.0 통계패키지 프로그램을 이용하여 t-검정, 단순선형회귀분석, 위계적 회귀분석을 통해 일·생활 균형, 부모 자신감, 경력관리의 구조적 관계를 규명하였다. 실증분석에는 총505개의 데이터를 활용하였으며, 결과를 요약하면 첫째, 성별에 따른 일·생활 균형 인식수준에 차이가 없는 것으로 나타났으며, 둘째, 일·생활 균형이 부모 자신감에 정(+)의 영향을 미치는 것으로 나타났다. 마지막으로 일·생활 균형이 부모자신감에 미치는 영향관계에서 조직차원의 경력관리가 조절역할을 하는 것으로 나타났다. 이러한 연구결과를 바탕으로 기혼여성인력 활용 및 일·생활 균형지원을 위한 기업의 노력 등에 관한 실용적 시사점 등을 제안했다.
