  • 소비자의 수용도에 중점을 둔 저염젓갈의 품질 기준을 설정하기 위하여 출하 직전의 시판 젓갈을 반제품과 완제품의 형태로 $30^{\circ}C:$에 저장하여 품질 저하를 시키면서 관능검사와 이에 따른 이화학적 검사를 병행하였다. 명란젓갈의 경우 Brix가 반제품 $47.6\%$ 이상, 완제품 $41.2\%$ 이상이면 합격품으로 판정되었으며 제조회사 별로 절대값의 차이는 있었지만 백색도도 소비자의 수용도가 떨어질 수록 증가하는 경향을 보였다. 반면, 오징어 젓갈은 원료의 특성상 백색도는 기준으로 설정하기 어려웠으나 Brix는 제조회사 별로 기준을 설정하면 소비자 수용도와 상관관계를 설정할 수 있을 것으로 추정되며 pH도 같은 경향을 나타내었다. 결론적으로 저염젓갈의 품질 평가는 관능적 평가와 이론학적 검사를 병행하는 것이 타당하며 이화학적 검사 항목으로 Brix, 백색도, pH 및 hypoxanthine 등을 들 수 있는데 이 중에서 Brix가 가장 좋은 기준이 되며 hypoxanthine은 제품에 따라 차이가 많아 좋은 기준이 될 수 없었으나 오징어젓갈의 경우는 제조 방법이 같을 때 유의할 만한 평가 항목이 될 것으로 판단되었다.

  • A team of researchers and practitioners were recently assembled to prepare a monograph on "Wind-Induced Motion of Tall Buildings: Designing for Habitability". This monograph presents a state-of-the-art report of occupant response to wind-induced building motion and acceptability criteria for wind-excited tall buildings. It provides background information on a range of pertinent subjects, including: ${\bullet}$ Physiological, psychological and behavioural traits of occupant response to wind-induced building motion; ${\bullet}$ A summary of investigations and findings of human response to real and simulated building motions based on field studies and motion simulator experiments; ${\bullet}$ A review of serviceability criteria to assess the acceptability of wind-induced building motion adopted by international and country-based standards organizations; ${\bullet}$ General acceptance guidelines of occupant response to wind-induced building motion based on peak acceleration thresholds; and ${\bullet}$ Mitigation strategies to reduce wind-induced building motion through structural optimization, aerodynamic treatment and vibration dissipation/absorption. This monograph is to be published by the American Society of Civil Engineers (ASCE) and equips building owners and tall building design professionals with a better understanding of the complex nature of occupant response to and acceptability of wind-induced building motion. This paper is a brief summary of the works reported in the monograph.

  • Purpose: This study was to develop a client health status outcome evaluation instrument, and examine content validity, reliability, construct validity, and the acceptability of this instrument. Method: A preliminary list was made of such key information as standards, criteria, indicators and measures, by means of a broad review of literature within the field. After determining the preliminary instruments, the study sought to obtain examination, consensus, and modification of two groups of experts in the home-care field. Finally, the instrument examined content validity, reliability, construct validity, and the acceptability of this instrument. Result: The tool was considered of 13 criteria, 48 indicators, and 167 detail measures. The content validity index of the tool was above 0.8 according to the expert group. Regarding the reliability of the evaluators of standards 1 and 2, the degree of agreement between evaluators was high(96.4% through 98.2%). Construct validity in this study, the difference in the mean score between the baseline point and the follow up point of each of standards 1 and 2 was significant, and the mean score of the follow up point was more than that of the baseline point. After examining the acceptability of this instrument with practice managers and home care nurses in home care institutions, a positive opinion was given of this instrument, and it was indicated that to be useful and applicable in home care practice. Conclusion: The results of evaluating client outcome will contribute to overall outcome-based quality improvement and service marketing in home care by providing a constant gauge of home care effectiveness.

  • Current vibration serviceability assessment criteria for wind-induced vibrations in tall buildings are based largely on human 'perception' thresholds which are shown not to be directly translatable to human 'acceptability' of vibrations. There is also a considerable debate about both the metrics and criteria for vibration acceptability, such as frequency of occurrence or peak vs mean vibration, and how these might vary with the nature of the vibration. Furthermore, the design criteria are necessarily simplified for ease of application so cannot account for a range of environmental, situational and human factors that may enhance or diminish the impact of vibrations on serviceability. The dual-site VSimulators facility was created specifically to provide an experimental platform to address gaps in understanding of human response to building vibration. This paper considers how VSimulators can be used to inform general design guidance and support design of specific buildings for habitability, in terms of vibration, which allow engineers and clients to make informed decisions with regard to sustainable design, in terms of energy and financial cost. This paper first provides a brief overview of current vibration serviceability assessment guidelines, and the current understanding and limitations of occupants' acceptability of wind-induced motion in tall buildings. It then describes how the dual-site VSimulators facility at the Universities of Bath and Exeter can be used to assess the effects of motion and environment on human comfort, wellbeing and productivity with examples of how the facility capabilities have been used to provide new, human experience based experimental research approaches.

  • The transmission pipeline industry spends many millions of dollars annually performing inline inspections, excavating sites of possible corrosion, and repairing or replacing damaged sections of pipe. New criteria for evaluation the integrity of corroded pipe have been developed in recent years to help in controlling these costs. These new criteria vary widely in their estimates of integrity and the most appropriate criterion for a given pipeline is not always clear. This paper presents an overview, comparison and evaluation of acceptability criteria for corrosion defects in pipelines. By full scale burst tests, this paper have assessed the relative accuracy of each of theses criteria in predicting failure and remaining strength. Many of the criteria appear to be excessively conservative and indicate that defects must be repaired when none is needed, based upon burst test data.

  • An integrated waste management approach for irradiated graphite was developed during the European Commission project 'Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste'. This included the identification of potential options for the management of irradiated graphite, taking account of storage, retrieval, treatment and disposal methods. This paper describes how these options can be assessed using multi-criteria decision analysis (MCDA) for a case study relating to a generic power reactor. Criteria have been defined to account for safety, environmental, economic and socio-political factors, including radiological impact, resource usage, economic costs and risks. The impact of each option against each criterion has been assessed using data from the project and the wider literature. A linear additive approach has been used to convert the calculated impacts to scores. To account for the relative importance of the criteria, example weightings were allocated. This application has shown that MCDA approaches can be used to support complex decisions regarding irradiated graphite management, accounting for a wide range of criteria. Use of this approach by individual countries or organisations will need to account for the specific options, scores, weightings and constraints that apply, based on their national strategies, regulatory requirements and public acceptability.

  • In this paper, by a simple example it is shown that existing market-based criteria alone cannot completely and correctly evaluate the transmission network expansion from market view. However criteria congestion cost (CC) and social welfare (SW) together are able to correctly evaluate transmission network from market view and so they are adopted for the market-based transmission expansion planning. To simply indicate the limits of CC and SW social welfare percentage (SWP) and congestion cost percentage (CCP) are defined. To consider uncertainty in bids of market producers and consumers, and also indeterminacy in the acceptable boundaries of the SWP and CCP and their priorities, fuzzy assessment approach is used. In this approach, appropriate fuzzy sets and a fuzzy rule base are provided to evaluate the acceptability of an expansion plan. Then, the least-investment cost plan, which is acceptable in all probable scenarios, is searched. The proposed method is applied to an 8-bus system.
