To identify and evaluate the risk factors in WMSD work, a number of ergonomic workload evaluation methods have been developed. In the legal examination of WMSD risk factors, simple observational workload evaluation methods are widely used instead of using costly measurement equipments such as EMG and motion analyzer. The simple workload evaluation methods can be categorized into three groups; risk factor checklist methods, posture observation methods, and manual material handling task evaluation methods. In terms of the categories, this survey summarized several representative workload evaluation methods and compared them each other. Then some industrial application cases referring each the workload evaluation methods were surveyed. Due to the characteristics of each method, the selection and application procedure of workload evaluation method should be appropriate for the corresponding work. Therefore, some guidelines for the selection and application procedure of workload evaluation method were suggested.

The aim of this study is to analysis factors that determine the competitiveness of container ports using the KJ and AHP methods. For this, 54 detailed attributing factors were identified both by previous studies and port users. 24 attributing factors were identified by a group of port experts. also, These were grouped 18 detailed attributing factors into 6 attributing factors by a group of port experts using the KJ method. These were made into a model of hierarchical structure with 3 levels, taking 1 goal factor, 6 evaluation factors and 18 detailed evaluation factors. The collected date of questionnaires were analyzed by a group of port experts using the AHP method. The analysis result of the evaluation factors in container port shows that port cargo volume is the most important factor, followed by port location, port cost, port service, port facility and port management. The analysis results of detailed evaluation factors in container port shows that import and export cargo volume is the most important factor, followed by transshipment cargo volume, distance from main trunk, cargo handling cost, distance from the point of importing and exporting, speediness of cargo handling, stability of cargo handling, vessel/cargo cost in port entry and leaving, punctuality in port entry and leaving, number and length of berth, collateral service cost, terminal area, hinterland accessibility, ability of terminal operation company, front depth of berth, etc.

바이오인식 (Biometrics) 시스템의 사용이 보편화 되면서 그들의 성능에 대해서 보다 정확하고 안정된 평가를 제공하는 방법이 요구된다. 다양한 바이오 인식 기술 중에서 얼굴인식 기술이 널리 사용되고 있으며 안정적인 얼굴인식 시스템의 개발을 위한 지표를 마련하고 얼굴인식 시스템이 제공해야 하는 성능에 대한 기준을 제시하기 위해서 얼굴인식 시스템의 성능을 평가해야 할 필요성이 커지게 되었다. 하지만 얼굴인식 시스템의 성능에 영향을 미치는 요소들이 매우 다양하고 복잡하기 때문에 얼굴인식 시스템의 성능을 평가하는 것은 어려운 일이다. 그렇기 때문에 이러한 환경요소에 대해서 개별적으로 평가하는 것보다 종합적으로 얼굴인식 시스템의 활용 시나리오를 기반으로 평가하는 것이 보다 효율적이고 효과적이다. 이 논문에서는 얼굴인식 시스템에 영향을 미치는 환경변수들을 분석하고 그 환경변수들을 고려하는 얼굴인식 시스템에 대한 평가방법을 제안하는 것을 목적으로 한다. 특별히 환경변수들을 개별적으로 평가하는 것이 아니고 그들의 조합을 고려하는 시나리오를 기반으로 평가하는 방법을 제안한다. 또한 일반적인 환경을 가정하는 시나리오 예시를 통해서 얼굴인식 시스템을 종합적인 환경변수를 고려하여 평가하는 것을 보여주었다.

Recently, information technology and information system(IS) are rapidly diffused throughout the world. In the global competitive environment, the success of IS becomes the important one among the critical success factors(CSF) of the firm. For achieving it, the firm must continually involve itself in the quality evaluation and improvement of IS. The quality concept was changed into the customer-oriented quality one. There is no exception to the quality of IS. In the past, IS quality was determined by the IS developer or IS department offering service. Now it is evaluated by the user of IS service, and then the customer-oriented user satisfaction becomes an important issue. The purpose of this study is to develope the total quality evaluation model of IS through TQM approach. First, all success factors of the domestic IS are extracted from the foreign and domestic literatures of IS success factors contained the technical and behavioral aspects. And the extracted factors are classified with evaluation levels for quality evaluation and developed into a total quality evaluation model. Finally the model usefulness is analyzed.

The scientific evaluation on enterprise helps establishing better management policy. Financial index has been used for the enterprise evaluation as the objective data. However, the necessity of the subjective data for competitive power evaluation is advocated recently. Therefore, in this paper, we propose an evaluation model of competitive power on enterprise by fuzzy integral, using the objective and the subjective data. The evaluation factors are composed to the financial index, top management, product, organization and enterprise's environment. These factors are grouped by detailed sub-factors of 16 units. Lastly, utilizing these factors, the efficiency of this method was shown by the result of the case study of 10 manufacturing enterprises.

For the environmental noises has various frequency spectrums and fluctuation characteristics. the dimensions of psychological influencing on persons IS also complex. Analyzing this complex-dimensional psychological factors and characteristics of them then developing the evaluation indexes which have a good correspondence are important for improvement of noise environment. To develop the effective evaluation procedures which reflect the psychological respects of persons, this study firstly we drove the psychological factors and classified the noises into several groups by their psychological response characteristics through the psycho-acoustical experiments using environmental noises. In addition, we analyzed the relationship between the various evaluation indexes, psychological factors and the noise groups, and then suggested several indexes for the simple and efficient psycho-acoustic evaluation.

This research aims to verify individual and organizational factors that will affect knowledge sharing, especially in research & development organizations with a premise that knowledge sharing is one of the most important factors of successful knowledge management. Many factors which are supposed to affect knowledge sharing arc empirically investigated in this research : individual factors ((1)self esteem (2)expected contribution), organizational factors ((3)top management's will, (4)accessibility of knowledge management system (5)validity of evaluation & reward knowledge sharing, (6)trust, (7)open communication). As a result, it is found that 'expected contribution' among individual factors and 'open communication' and 'validity of evaluation & reward' among organizational factors are highly correlated with knowledge sharing. These findings suggest that enhancement of perceived expected contribution among employees and building cultures of open communication and effective evaluation & reward system for knowledge sharing will contribute to activation of knowledge sharing in the research and development organizations.

The purpose of this study is to analyse the main factors and attributes of psychological evaluation to noise. For this purpose, a psycho-acustic experiment was conducted by using the method of rating scale. 52 subjects were participated in the experiment, 20 stimuli were presented to subjects in random order with 23 adjectives. As a result of factor analysis, it was found that the primary factors for evaluating the quality of noise subjectively are four factors of unpleasantness, intensity, irregularity, and sharpness. And, as a result of MDPREF(multi-dimensional analysis of preference data), it was found that the noise sources including the factors of unpleasantness, intensity, and irregularity are related to the sounds of hammering in construction field, car horn, road traffic, idling of car, and printing by computer printer, and the factor of sharpness are the sounds of car siren, claps of thunder, car horn, and snowstorm etc.
