  • The government introduced the comprehensive evaluation bidding system with the goal of pursuing the best value and the global standard in 2016. However, for the evaluation criteria on the construction evaluation reflected to the comprehensive evaluation bidding system, the problems of the objectivity insufficiency, the inclusion of multiple subjective evaluation items, and the irrationality of the weight for each evaluation item are continue to be presented. The central office group, the local government, the relevant industry, and the expert group share recognition, but the solution is not derived. Hence, the major evaluation items to be improved were derived with the characteristics analyzed to secure the objectivity of the construction evaluation. For the analysis method, the standard deviation and the Fleiss Kappa analysis method were used by utilizing the characteristics that the construction evaluation criteria consist of all 4-point measures (good, average, insufficient, and poor). According to the result, the 10 evaluation items of the total 25 construction evaluation items were derived as the evaluation items to be improved. It was found in the analysis on the major characteristics of the derived evaluation items that the qualitative evaluation criteria such as 'Very Suitable' and 'Suitable' were commonly included in the detailed evaluation guidelines. Hence, as far as the future construction evaluation standards are concerned, the qualitative evaluation standards are sublated, and the improvement should be made mainly for the quantitative evaluation criteria enabling the objectivity assurance.

  • In order to find correlations between the sensory evaluation and instrumental analysis in 'Campbell Early' grape, grapes were divided into three parts. One-half parts were used for the sensory evaluation and the other half were used as samples for instrumental analysis. Relationship between sensory evaluation and instrumental analysis were studied through correlation study using 48-paired data set obtained during storage. Soluble solid content analysis showed that instrumental quality attributes increased along the passage of storage time with increasing temperature. pH and titratable acidity decreased slightly at lower storage temperatures. Correlations between instrumental quality attributes in grapes were found to be very low. Positive correlation was found between pH and soluble solid content, and negative correlation was found between pH and titratable acidity. The relation of sourness and sweetness to sourness was higher than other sensory evaluation factors, and the shape of the grapes was found to have little relation to their sweetness. Texture ($r^2$=0.890) was found to be the most important factor in preference, followed next by sweetness with sourness ($r^2$=0.860). The correlations between the sensory evaluation and instrumental quality attributes were found to be very low, with overall acceptability given to a relatively high content of soluble solid content. Correlations between pH and titratable acidity in terms of overall acceptability were found to be very low.

  • Consumers influence other consumers' brand choice behavior by delivering a variety of objective or subjective information on a particular product, which is called WOM (Word-Of-Mouth) activities. For WOM activities, WOM senders should choose messages to deliver to other consumers. We classify the contents of the messages a consumer chooses for WOM delivery into two categories: Subjective (positive or negative) evaluation and objective information on products. In our study, we regard WOM senders' activities as a choice behavior and introduce a choice model to study the relationship between the choice of different WOM information (WOM with positive or negative subjective evaluation and WOM with objective information) and its influencing factors (information sources and consumer characteristics) by developing two bivariate Probit models. In order to consider the mediating effects of WOM senders' product involvement, product attitude, and their characteristics (gender and age), we develop three second-level models for the propagation of positive evaluations, of negative evaluations, and of objective information on products in an hierarchical Bayesian modeling framework. Our empirical results show that WOM senders' information choice behavior differs according to the types of information sources. The effects of information sources on WOM activities differ according to the types of WOM messages (subjective evaluation (positive or negative) and objective information). Therefore, our study concludes that WOM activities can be partially managed with effective communication plans influencing on consumers' WOM message choice behavior. The empirical results provide some guidelines for consumers' propagation of information on products companies want.

  • An objective Bayesian estimation procedure of the two-parameter Pareto distribution is presented under the reference prior and the noninformative prior. Bayesian estimators are obtained by Gibbs sampling. The steps to generate parameters in the Gibbs sampler are from the shape parameter of the gamma distribution and then the scale parameter by the adaptive rejection sampling algorism. A numerical study shows that the proposed objective Bayesian estimation outperforms other estimations in simulated bias and mean squared error.

  • This essay suggests a constructive interpretation of probabilities by diagnosing problems of the objective and the epistemic interpretations of probability. According to this interpretation, attributions of the mathematical structure of probability to a given system can be understood as positing constructive theoretical hypotheses showing the relationship among empirical data. The constructive interpretation is applied to comprehend probability claims in the explanation of temporal asymmetrical behaviour of our universe. A new approach interpreting probabilities as constructive theoretical terms enables us to circumvent shortcomings of both objective and subjective interpretation of probability, and appreciate why these interpretations nevertheless appear to be convincing in our case.

  • Auditors' subjective opinions m audit activities weaken reliability in audit judgments. This paper suggests fixed quantity models through requirement priority for improving objective evaluation and priorities of requirements in information system audit. The value of requirements was evaluated based on customers' requirements with a premise that they are not in the same level. Furthermore, the audit objective judgments were enhanced to enable fixed quantity of subjective audit by subdividing detailed evaluation index of requirement priority standards into importance of service and function on orderers' perspective, and sectioning cost and schedule on contractors' perspective.

  • This paper presents an objective video quality evaluation method for digital mobile video. The proposed method is to objectify subjective quality by extracting edge region feature metric and blockiness effect. To evaluate performance of proposed algorithm, we carried out subjective video qualify test with the DSCQS method and obtained mean opinion score(MOS) values for CIF/QCIF 140 video clips. We compared error of proposed method with that of existing. The experiment results show that the proposed method has 25% higher performance.

  • 하천의 건강성을 유지하고 수환경의 정상적인 기능을 회복하기 위해서는 수서생물들에게 알맞은 서식환경 조성, 점오염원 및 비점오염원 차단, 적절한 유량과 같은 다양한 조건이 요구된다(Gore 1895; Gore et al. 1989). 이 중 유량은 수생태계를 이루는 물리적, 화학적, 생물학적 요소들 가운데 기본이 된다고 할 수 있다(Bunn and Arthington 2002; Nilsson and Svedmark 2002; Arthington et al. 2006). 국내 하천관리를 위한 하천유지유량의 산정에서 고려하고 있는 갈수량, 하천생태계, 하천수질 등 8가지 항목 가운데 최근 생태계와 환경에 대한 사회적 국민적 관심이 증가하면서 하천생태계를 고려한 환경유량의 중요성이 부각되었으나, 현실적으로 생태계를 고려한 정량적 조사자료 구축 및 환경유량산정 등의 객관적 자료는 미흡한 실정이다. 특히, 과거 해당수계 및 하천의 어류분포 현황 파악을 중심으로 이루어진 어류조사는 환경유량 산정 시 기초자료로 활용하거나 직 간접적으로 어류상이 변화하는 원인을 분석하는 자료로 활용하기에는 객관성이 결여되어 있다고 할 수 있다. 어류모니터링 기법 확립은 환경유량산정에 있어 요구되는 정량화와 자료의 객관성을 높이기 위한 작업으로 문헌조사와 청문조사를 포함한 사전조사, 현장조사, 조사결과 정리, 고찰 등의 총 4가지 과정을 기본으로 실시하는 것으로 정하였다(그림. 1), 청문조사와 문헌조사 등의 사전조사를 통해 기존자료를 확보하고 현장의 답사, 조사구간, 방법, 시기 등의 선정을 통해 두 번째 단계인 현장조사의 효율성을 높였다. 현장조사에서는 어류분포 현황 외에도 해당지점의 하상재료, 식생, 유속, 수심, 수질 등 조사지점의 수 환경요소 전반을 기록하여 어류의 서식과 물리 화학적 수환경과의 상호관계를 파악하고자 하였다. 마지막으로 고찰단계에서는 조사 대상 지역 전반적인 어류상 특징과 함께 보호종, 한국고유종, 외래도입종 출현유무 및 빈도, 물리적, 화학적 수환경의 특징, 수환경에 따른 어류상 특징 등의 분석과 함께 조사하천의 건강성을 평가하고자 하였다. 본 연구는 어류모니터링 기법 확립을 통해 환경유량산정 시 요구되는 객관적 기초자료를 구축하고 나아가 오염물질 유입, 하천정비사업 등의 각종 교란요인에 의해 발생할 수 있는 문제점들에 능등적으로 대처하고 교란에 의해 악화된 수환경의 복원을 위해 요구되는 객관적 기초자료 생산에 목적이 있다.
