  • Due to the high interests of image quality by consumers, the concerned market becomes more heated. Recent digital camera development tendency shows to perform the higher image quality to meet consumers demand of quality satisfaction. However it is hard to confirm that development of objective image quality performance means positive subjective image quality preference. And also, we cannot find out the previous researches concerned on correlation between objective and subjective image quality comparison. Therefore, it is necessary to analyze the consumers preferred images based on objective image quality performance. Throughout this paper, we analyze statistical correlation between the objective and subjective image quality assessment methods by using ISO standards. In these results, we try to find attributes that enhance image quality. We suggest not only to analyze and reflect on customers' preferences, but also to pursue the high quality image performance practically. We expect the results of this paper to positively influence product development.

  • 국가의 미래지향적 정책을 위해서는 무엇보다도 이를 선도해나아갈 핵심인재의 확보가 매우 중요하다. 이러한 핵심인재 확보를 위해 각 부처에서는 지역 R&D 인력양성과 관련된 사업이 진행 중에 있다. 지역 R&D 인력양성사업의 전담기관은 시기와 목적에 따라 변경될 수 있으며, 변경될 때마다 사업목적과 수단이 부합하는지를 점검하기 위하여 사업성과를 객관적으로 분석 및 평가하고 그 결과를 새로운 사업계획 설계에 반영할 필요성이 제기되어 왔다. 그러나, 지역 R&D 인력양성사업은 전담기관 및 사업의 성격에 따라 성과분석 모형을 다르게 적용해 왔으며, 객관적 성과 분석 프레임워크가 부재하다. 따라서, 본 논문에서는 인력양성사업의 특성을 파악하여 객관적으로 분석 및 평가에 활용할 수 있는 성과 분석 모형을 설계하고자 한다.

  • 본 연구는 영국의병원 급식체계를 분석하고 그에 대한 객관적, 주관적 평가를 시도하는데 목표를 두고 있다. 영국 보건성의 지원하에 12개 병원에 대한 급식체계를 비용편익 분석과 생산성 측정이라는 객관적 기법, 그리고 Indepth-interview 및 Self-Administered Qestionnaire 라는 주관적 방법을 통해 분석하였다. 이 중 본논문에서 다루는 것은 환자 만족도와 이에 영향을 미치는 병원 급식 체계의 결정요인 부분이다. 제1단계 연구에서는 급식대상 환자들에 대한 표본추출을 통해 설문조사를 실시하였다. 분석결과 환자의 인구통계학적, 정서적 변수가 환자의 만족도에 가장 큰 영향을 미치는 요소로 나타났다. 각병원에 대한 객관적 자료를 이용한 2차 희귀분석 결과 인적자원요소와 시스템요소로 대별된 독립변수 요인군종 어느 변수도 0.05(p) 수준에서 유의미하지 않은 것으로 밝혀졌다. 환자의 만족도는 병원 급식체계에 기준한 객관적인 결정요인에 의해 설명되어지지 않고 오히려 환자 자신의 변수에 의해 결정되어짐을 알수 있다. 본논문이 시사하는 바는 급식체계에 대한 평가에 있어 이론적 모형과 변수의 선정이 수정될 필요가 있다는 점과 방법론적 차원에서 평가대상 급식시스템의 유형상 특성이 고려되어야한다는 점이다.

  • Subjective cognitive-linguistic complaints in older adults contribute to the diagnostic and prognostic investigation of MCI or dementia. However, the utility of subjective test for predicting cognitive-linguistic decline is controversial. Few domestic studies have included the correlation between subjective and objective tests systematically. The current study analyzed 26 studies published since 2000, and the effect sizes of their correlation coefficients between two tests were computed. The results of qualitative analysis indicated that the number of subjects ranged from 26 to 657. Subjective tests included the self-report 75.4% and the informant-report 24.6%. In objective tests, memory comprised the largest proportion, followed by global cognition, and language, etc. As a result of meta-analysis, self-report test had the predictive value for dementia, and informant-report test contributed to discriminate among 3 groups. In the elderly group, self-report test was correlated with reasoning, and informant-report test with memory and language. In MCIs, self-report test predicted several abilities including language, and informant-report test signaled the future decline of domains like global cognition. Two types of subjective tests in dementia also represented memory, language, and global cognition accurately. This study provides evidence-based information to support relationships between subjective and objective tests for cognitive-linguistic ability in 3 groups.

  • The purpose of this paper is to compare learners' academic texts with academic texts of native speakers and to examine the usage patterns of learners' objectification strategies in detail. In order to achieve objectivity as a discourse mechanism applied to describe the results of academic inquiry in a scientific way with universality and validity, we analyzed concepts and signs such as related intentionality, accuracy, and mitigation of the linguistic markers of objectification strategies. As a result of the comparison, it was analyzed that there are intersectional overlaps with the signs that reveal objectivity, signs indicating related mechanisms, and there is a different set that is differentiated. Objective markers can be broadly classified as emphasizing stativity of research results, separating research subjects from research results, and generalizing research contents. Sustainable expressions and noun phrases emphasize statehood, and non-inhabited expressions, passive expressions, and self-quotations are maintained in the distance between the claimant and the writer, and the pluralization through first-person pronouns and suffixes contributes to generalization. In the case of the learner, the non-inhuman expression of the quotation type appears to be very less compared to the maw speaker, which could be due to the lack of recognition of the citation method of the Korean academic text. Next, in the generalization of the research contents, the expression of 'we' was very less compared to the maw speakers.

  • The purpose of this study was to analyze the items that were used in entrance examination for science gifted education center for middle school students by using content analysis and classical item analysis. In content analysis, objective type items exhibited mathematics and physics were dominant. Science giftedness & creativity items were dominant. And essay type items consisted of physics items, have evaluated creative problem solving ability. Item difficulty and discrimination index, on the whole, were appropriate. Comparing with objective type, essay type has higher discrimination index. In correlation analysis between total score and score of each type of items, total score has the highest correlation with essay type items and science giftedness & creativity. It was recommended that mathematics, physics and chemistry items with focusing giftedness & creativity could give some implications for future selection methods of science gifted education center.

  • Previous studies, while investigating factors of sensibility, had rarely considered its internal structure. This study hypothesized that sensibility had sensational aspects and emotional aspects and the former corresponded to objective adjectives, describing attributes of objects, and the latter to subjective adjectives, describing psychology of experiencers. Forty-three objective adjectives and 21 subjective adjectives describing color sensibility were selected both by a linguistic criterion and an empirical evaluation. Factor analysis on semantic differential responses to these two groups of adjectives resulted in 5 sensational factors and 3 emotional factors of color sensibility respectively. Hierarchical structure was derived by regressing emotional factor scores on sensational factor scores. In consequence, emotional aspects were interpreted by different combinations of sensational factors. Limitations and significance of this study were discussed.
