Based on the indiscernible relation of rough set, the inevitability of superposition and inconsistency of data makes the reduction of attributes very important in information system. Rough set has difficulty in the difference of attribute reduction between consistent and inconsistent information system. In this paper, we propose the new uncertainty measure and attribute reduction algorithm by Bayesian posterior probability for correlation analysis between condition and decision attributes. We compare the proposed method and the conditional information entropy to address the uncertainty of inconsistent information system. As the result, our method has more accuracy than conditional information entropy in dealing with uncertainty via mutual information of condition and decision attributes of information system.

The purpose of the present study was to examine the validity and reliability of the Korean version of PANSI(Positive and Negative Suicide Ideation: K-PANSI) scale which was developed to measure adolescents' suicide ideation. The study sample consisted of 552 middle school students using a questionnaire survey including the K-PANSI. A reliability analysis, a correlation analysis, and a confirmatory factor analysis were used to test internal consistency(Cronbach alpha), criterion validity (with respect to CES-D, BDI, RES, SWLS), and construct validity. Major study findings are as follows. First, Cronbach' ${\alpha}$ of the K-PANSI scale is supported to some degree by significant correlations with CES-D, BDI, RES, SWLS. Lastly, the confirmatory factor analysis of the K-PANSI scale showed that a two factor model was appropriate with 66.0 percent of explanatory power. These findings suggest that the K-PANSI scale could be used as a reliable and valid measure for adolescent' suicide ideation.

기존의 일관성 개념은 임의적인 평가를 가정하고 있으며, 실제 AHP procedure에 반영되는 개념의 기준이 아닌 RI를 통해서 정의 내리고 있다. 수식적인 관점에서도, 경험적인 상대 비율을 통해 CR이 계산되어지고 있으며, 타당한 평가행렬이 Discard될 수도 있다. 이상적인 평가기준을 제시하는 것이 요구된다. 본 연구에서는 기존 AHP 절차에 있어서 일관성 기준의 개념 및 적용과 9점 척도의 한계성에 의한 문제점을 제시하고 이 문제점을 개선할 수 있는 새로운 쌍대 행렬 평가기준을 제시하고자 한다.

본고는 서로 다른 용어와 기준들로 일관성 없이 나열되어 있던 이전의 '-이나'의 의미 해석을 통합적으로 설명해 보고자 한다. 즉 특정한 양상 척도(개연성, 희구성, ${\ldots}$ 등)을 이용하여 '-이나'가 쓰인 맥락에 따라 척도 함축을 해석해 내고자 한다. 따라서 본고는 교착어의 특성을 가진 한국어의 특수조사(혹은 한정사) '-이나'의 함축 해석에서 척도의 유형을 분류함으로써 의미 해석과 형식화의 초석을 다지는 연구가 될 것이라고 기대한다. 먼저 '-(이)나'의 함축 해석에서 나타나는 척도의 유형에 대하여 논의하고자 한다. 따라서 '-(이)나'의 함축이 드러내는 척도들을 형식적으로'선형과 비선형'척도를 나누고 이러한 문장들이 들어내는 양상을 분류할 것이다. 둘째, 정대호 외(2002)에서 논의하고 있는 '~이나/도'가 분류사구와 결합한 문장이 화용론적인 개연성의 척도상에서 하한 값을 유발한다고 제안함에 따라, 본고는 양상을, 이러한 개연성의 척도를 포함한, '인식(진리, 원인, 지식, 평가), 의무(의지), 희구(기원)'의 3가지 양상으로 분류하고, 이에서 '-(이)나'가 유발하는 각각의 척도상의 함축을 기술할 것이다.

Significant research has been devoted to the consistency index of the Analytic Hierarchy Process(AHP) from several perspectives. Critics of the consistency index in AHP state that the critical value of consistency index depends on an average of the random index based simulation study using a 9 scale comparison matrix. We found that the distribution of the consistency index followed the skew distribution according to the dimension of the comparison matrix based on a simulation study with a 9 scale comparison matrix. From the simulation study, we suggest a consistency index quantile table to assist the decision-making process in AHP; in addition, we can approximate the distribution of the consistency index to the gamma distribution under the limited assumptions.

The primary objectives of this study are twofold. One is to examine the psychometric properties of Family Empowerment Scale(FES) developed by Koren, DeChillo and Frisen(1992). The other is to develope a short-form FES. Data collected from 337 members of Parents' Solidarity of Children with Disabilities were used. FES had good internal consistency, but the results of confirmatory factor analysis(CFA) did not support the theoretical factor structure of the scale. Basic analyses such as correlation and descriptive analysis were performed to examine the characteristics of individual items and identify the limitation of the orignal FES. In addition, a series of CFA were carried out to develop a short-form FES. Finally 15 items were selected based on theoretical rationale and the results of CFA. Cronbach's ${\alpha}$ and the model fit indices for the short-form FES indicated that this measure has good construct validity as well as internal consistency. In discussion, usefulness and potential contribution of this study were explored in relation to content development in the area of measuring instruments.

본 연구의 목적은 수작업 반복성 평가의 체계적인 연구를 위해 최근 5년간의 반복성에 관한 기존 연구 30여 편을 중심으로 반복성 평가 방법들을 조사하여 비교 분석하는 것이다 기존연구들의 비교 분석 결과, 평가하고자 타는 반복성의 근본적인 이해가 부족하여 반복성 정의에 대만 일관성이 없을 뿐만 아니라 반복 수준의 구분 기준에 대한 척도간 비교가 어렵고 결과의 일관성도 없었다. 본 연구에서는 기존 연구들의 무분별만 평가로 인한 문제점을 해결하기 위하여 시간(time)과 빈도수(frequence)를 기준으로 타는 평가 적도의 새로운 분류 체계를 제안하였다. 마지막으로 평가 적도의 측정과 분서에 사용되는 방법들을 조사하여 정리하였다. 본 연구의 결과는 수작업의 반복성 평가를 위한 척도의 사용지침을 제공할 뿐 아니라 추후 반복성 평가의 체계적인 방법론을 구축하는데 근간이 될 수 있을 것이다.

The purpose of this study was to develop and validate Korean Game Addiction Scale for children and adolescents. Data from a representative sample of 3,115 children and adolescents residing in Korea were analyzed to identify the factor structure and reliability of the scale. In addition, criterion-related evidence of validity (concurrent and convergent) was examined. Consistent with our theoretical assumptions, the Korean Game Addiction Scale revealed a stable higher order factor structure (second order-one factor, first order-seven factors), and the reliability of the scale was high (average Cronbach's alpha = .84, six week test-retest reliability = .75). The scale was also showed high levels of concurrent and convergent validity. Implications of the findings and directions for future research on game addiction are discussed.

This study is about the scale to evaluate the data of the countermeasures in the 'simulation based government exercise' (tentative name). The criteria and weighting of the scale is a standard for evaluating the data of each agency input. This maintains the objectivity and consistency of the evaluation, which complements the subjective evaluation of the observer. Therefore, the criteria should accommodate the purpose of the government exercise evaluation, the possibility of measurement in the simulation environment, the objectivity, no-duplication and causality between criteria, and the grade applying the evaluation results, and the weighting should be set. In this study, three major criteria of timeliness, accuracy, and appropriateness is set up for the evaluation scale and it consists of sub-criteria classified into three classes below respectively and the concept of it was defined. The weighting was calculated by AHP analysis considering the hierarchical structure of it. When this evaluation scale is applied to the 'simulation based government exercise' in the future, it will be possible to secure consistency and objectivity of the evaluation of measures by integrating the quantified evaluation into the observation evaluation and to conduct AAR by scientific techniques.

It is expected that logistics standardization have an great effect on industry and national economy due to cost saving and improving efficiency. Therefore all countries of the world make a strenuous effort to take a lead of logistics standardization Despite such efforts of every country, our country remained a lukewarm attitude about logistics standardization. Especially, our country remained a lukewarm attitude about logistics standardization effect quantify. We have to suggest the necessity of standardization and the effect for carrying out logistics standard. So, this study performed literature review and case study for development of effect valuation method. Also, this study developed effect valuation standard for quantifiable standardization effect and drew the effect valuation standard model. First, the measure of preliminary effectiveness was chosen for MOE selection. As a results, vehicle load ratio, delivery cost, keeping space efficiency warehouse automation ratio, etc. were selected. Then, vehicle/truck load ratio, warehouse keeping efficiency, up unloading hour, packaging cost, consistency transportation ratio were chosen for MOE of pallet standardization.
