The objective of this study is to empirically develop performance evaluation measures for LIS (logistics information systems) based upon BSC (balanced scorecard) model and determine the relative importance among four perspectives of BSC using AHP (analytic hierarchy process) methodology. Above all, forty nine probable measures for evaluating LIS performance were identified through reviewing the previous research related with SCM (supply chain management), logistics management, and information systems evaluation. And then, these probable measures were examined by means of coincidence analyses using three mutually exclusive criteria(validity of content, ease of measurement and reliability of measurement). Data for conducting the coincidence analyses were collected from LIS users and LIS development personnel. As the results of the coincidence analyses, it was found that 31 ones among 49 probable performance evaluation measures theoretically derived could be qualified for LIS performance evaluation. And AHP analysis showed that the weight of each perspective was respectively as follows : 46.8% for financial perspective, 31.3% for customer perspective, 14.8% for internal business process perspective, and 7.1% for learning and growth perspective. The academic contribution of this study is that performance evaluation measures for LIS could be systematically and empirically developed on the basis of BSC. Also, the results of this study are expected to be used as a practice guideline of evaluating and improving LIS.

음성인식은 최근 인공지능 기술과 접목되면서 오인식률이 크게 개선되었고 사용자 관점에서 효과적이고 효율적인 HMI(Human Machine Interface)를 제공하고 있다. 이러한 추세는 방위산업 분야에서도 반영되고 있고 특히 항공분야에서 F-35에 적용이 되었다. 하지만 이러한 기술에 대해서 품질평가를 위해 방위산업 특히 항공분야에는 객관적이고 평가 가능한 정량적인 모델이 필요하다. 본 연구에서는 이러한 음성인식의 소프트웨어 측면에서 항공기에 적용하기 위한 정량적인 평가 모델을 제시한다. 평가 모델 제시를 위해 음성인식 적용 기술과 ISO/IEC 25000(SQuaRE) 제품 품질 속성을 이용해 평가 항목을 추출한다. 이러한 두 가지 항목의 연계를 통해 정량적인 평가 모델을 제시하고 사례 연구를 활용해 평가 결과를 확인한다.

This research entailed the production of stereoscopic 3D (S3D) contents using 2D-to-S3D conversion for exhibition at a museum and subjective evaluation. Hybrid production combining S3D images of existing live-action videos using the 2D-to-S3D conversion technology and computer graphic ones created via stereo rendering was conducted. Design and control of the chronological analysis of the parallactic angle was conducted on the produced contents, using binocular information as well as subjective evaluations, with the intent of conducting an investigation on the characteristics of such contents from the perspectives of the producers and viewers. An investigation was also conducted on the effects of the viewing position on the impressions of the S3D images.

The purpose of this study was to examine the effect of interactivity on consumers' mental imagery, attitude toward a product, confidence in evaluation and purchase intention. The proposed model was examined by conducting an experiment using mock apparel websites. A total of 1,009 female college students enrolled at a major midwestern university in the USA participated in the experiment. A structural equation model was used to test the model. The results of the study indicate that interactivity positively influenced mental imagery, attitudes toward a product imagery, and confidence in evaluation. The structural equation model also revealed that mental imagery positively influenced attitude toward a product and confidence in evaluation. Finally, the results show that attitude toward a product and confidence in judgment positively affected purchase intention. The study provides valuable theoretical perspectives which aide in the understanding of the effect of interactivity on consumers' cognitive and behavioral responses, and helps retailers develop effective marketing strategies.

The purpose of this study was to examine the current student assessment plan of subject domain and to propose ways to improve it. This study analyzed the history of our student assessment plan of subject domain and overviewed the student assessment cases of several countries. And then researchers discussed the improvement plans of student assessment of subject domain. The results of this study are as follows. First, we need to enlarge the use of detailed subject-ability record space or to assess student's subject-related ability according to subordinate perspectives of subject. Second, we need to establish the desirable evaluation-perspective and to develop absolute evaluation criteria of each subject and unit. Third, we need to diffentiate the scores of differentiated test items or equate the scores of differentiated groups.

Object-oriented databases (OODBs) have been adopted for managing non-standard applications such as computer-aided design (CAD), office document management and many multimedia applications. One of the major characteristics of OODBs is class hierarchy where a subclass is allowed to inherit the definitions defined on its superclasses. In this paper, I present the evaluation metrics for class hierarchy quality in OODBs. These metrics are developed to determine if a concurrency control scheme can achieve good performance or not on a given class hierarchy. I first discuss the existing concurrency control schemes for OODBs. Then I provide evaluation metrics based on structural information and access frequency information in class hierarchies. In order to discuss significance of the proposed performance metrics, an analytical model is developed. Analysis results show that the performance metrics are important factor in concurrency control performance. I consider both single inheritance and multiple inheritance. The proposed metrics can be used to provide guidelines on how to design class hierarchy of an OODB for maximizing the performance of concurrency control technique.

A performance measurement system for safety management was suggested with which performance of a company's safety activities can be expressed rationally, and analysis of impact with performance improvement. A key of the measurement system is performance index of the safety management activities, which consists of 3 perspectives; an external perspective, an internal perspective, and a innovation & learning perspective. Every perspective consists of 18 performance indices and each indices consist of activity unit a such planning, support, implementation, evaluation and review.

Since the natural gas air-conditioning not only increases the base load of the gas company but also decreases the summer peak load of the electricity company, it is considerded as an efficient demand-side management program. This paper suggests the economic evaluation method of the gas air-conditioning program from the perspectives of the participants, the pipeline gas company, the local distribution company, the electricity company, and the total resources. The absorption type gas air-conditioning/space-heating is selected as a case study to illustrate the economic analysis of the natural gas air-conditioning.

What is radical constructivism There were many questions arose related with radical constructivism in mathematics education. In this paper, the author put seven frequentlyasked questions on radical constructivism and described each question one by one in light with constructivists' point of views. The questions included types of constructivista, radical constructivism, trivial or weak constructivism, and social constructivism; representative people in radical constructivism; matter of ontological reality; evaluation of others' work; shared meaning; social influence; and teacher's roles from the perspectives of radical constructivism. The author added his opinions ell each Question.
