This study investigated the degree to which instrumental measurements explain the variation in pork loin tenderness as assessed by the sensory evaluation of trained panelists. Warner-Bratzler shear force (WBS) had a significant relationship with the sensory tenderness variables, such as softness, initial tenderness, chewiness, and rate of breakdown. In a regression analysis, WBS could account variations in these sensory variables, though only to a limited proportion of variation. On the other hand, three parameters from texture profile analysis (TPA)-hardness, gumminess, and chewiness-were significantly correlated with all sensory evaluation variables. In particular, from the result of stepwise regression analysis, TPA hardness alone explained over 15% of variation in all sensory evaluation variables, with the exception of perceptible residue. Based on these results, TPA analysis was found to be better than WBS measurement, with the TPA parameter hardness likely to prove particularly useful, in terms of predicting pork loin tenderness as rated by trained panelists. However, sensory evaluation should be conducted to investigate practical pork tenderness perceived by consumer, because both instrumental measurements could explain only a small portion (less than 20%) of the variability in sensory evaluation.

Among the several options to solve PWR spent fuel accumulation problem in Korea, the dry storage method could be the most realistic and applicable solution in the near future. As the basic objectives of dry storage are to prevent a gross rupture of spent fuel during operation and to keep its retrievability until transportation, at the same time the importance of a spent fuel integrity evaluation that can estimate its condition at the final stage of dry storage is very high. According to the national need and technology progress, two representative nations of spent fuel dry storage, the USA and Japan, have established different system temperature criteria, which is the only controllable factor in a dry storage system. However, there are no technical criteria for this evaluation in Korea yet, it is necessary to review the previously well-organized methodologies of advanced countries and to set up our own domestic evaluation direction due to the nation's need for dry storage. To satisfy this necessity, building a domestic spent fuel test database should be the first step. Based on those data, it is highly recommended to compare domestic data range with foreign results, to build our own criteria, and to expand on evaluation work into recently issued integrity problems by using a comprehensive integrity evaluation code.

이 논문은 항공 분야에서의 안전필수 소프트웨어를 평가하기 위한 고려사항을 기술한다. 항공 분야에서의 안전필수 소프트웨어의 평가를 수행하기 위해서는 해당 소프트웨어의 평가 수준에 대한 정보가 필요하다. 그 수준은 표준에 명시되어 있으나 소프트웨어 자체적으로 결정되는 요소가 아니며 시스템 안전 평가 결과 및 시스템 설계 결과에 의존적이다. 그러므로 소프트웨어 평가수준을 결정하기 위해 시스템 개발 및 시스템 안전 평가 표준에서 필요로 하는 정보에 대해 설명한다. 그리고 소프트웨어를 평가하기 위한 기존의 방법론들을 조사하고 항공기 지상 유도 및 통제 시스템 소프트웨어의 평가에 적용할 방법을 제시한다.

Mental workload (MWL) is a major consideration for the user interface design in nuclear power plants (NPPs). However, each MWL evaluation method has its advantages and limitations, thus the evaluation and control methods based on multi-index methods are needed. In this study, fuzzy comprehensive evaluation (FCE) theory was adopted for assessment of interface designs in NPP based on operators' MWL. An evaluation index system and membership functions were established, and the weights were given using the combination of the variation coefficient and the entropy method. The results showed that multi-index methods such as performance measures (speed of task and error rate), subjective rating (NASA-TLX) and physiological measure (eye response) can be successfully integrated in FCE for user interface design assessment. The FCE method has a correlation coefficient compared with most of the original evaluation indices. Thus, this method might be applied for developing the tool to quickly and accurately assess the different display interfaces when considering the aspect of the operators' MWL.

In this study, the library ESG evaluation indicators specialized for libraries were developed, and based on which, a survey was conducted targeting the actual libraries to evaluate the ESG level of libraries. As a result of the study, first, among the ESG evaluation indicators, the indicators of the social field and the governance field are demonstrating high in which field of the library's ESG evaluation indicators will appear the highest. The social area's high score of 3.70 seems to be because the protection of users' rights, occupational safety, and contribution to society and the local community are very closely related to the original role of the library. Second, it may be seen that there is a difference between the questions in the corporate governance part, while the averages are the same. In the case of library's cooperation, it turned out that it was 3.94 in the necessity evaluation of the evaluation indicators, but it was lowered to 3.61 in the actual library situation evaluation. Meanwhile, in connection with the activities of the director of library and the board of directors, it may be seen that the index evaluation increased from 3.32 to 3.58 in the actual evaluation.

This study proposes a framework for an evaluation and selection of a venture firm with promising new technology in optical electronics industry to nurture that firm. The framework is intended to help practitioners to evaluate accurately and objectively new technologies. In addition, this study tests the usability and effectiveness of this framework with an actual certain case. More specifically, this study, first proposes that the framework for new technology evaluation is composed of financial perspective, market perspective, internal business perspective, and R&D and growing perspective. They are on the four perspectives of BSC(Balanced Score Card). Each perspective contains specific items. In addition, this study uses AHP(Analytic Hierarchy Process) to assess the comparative importance among the four perspectives and their specific items. Secondly, based on the results of AHP, the usability and effectiveness of the framework suggested in this study have been tested with a real case evaluating and selecting a promising venture firm. The results of the study have the following implications: this study has developed the framework for new technology evaluation which assists practitioners. Our framework offers the four perspectives and their specific items with their respective comparative importance. Furthermore, this study has verified that the proposed framework can be applicable in real situation with more accurate results.

A simulation program SIMULTSONIC is under development at CNDE to help determine and/or help optimize ultrasonic probe locations for inspection of complex components. SIMULTSONIC provides a ray-trace based assessment for immersion and contact modes of inspection. The code written in Visual C++ operating in Microsoft Windows environment provides an interactive user interface. In this paper, a description of the various features of SIMULTSONIC is given followed by examples illustrating the capability of SIMULTSONIC to deal with inspection of canonical objects such as pipes. In particular, the use of SIMULTSONIC in the inspection of very thin-walled pipes (with 450 urn wall thickness) is described. Ray trace based assessment was done using SIMULTSONIC to determine the standoff distance and the angle of oblique incidence for an immersion mode focused transducer. A 3-cycle Hanning window pulse was chosen for simulations. Experiments were carried out to validate the simulations. The A-scans and the associated B-Scan images obtained through simulations show good correlation with experimental results, both with the arrival time of the signal as well as with the signal amplitudes.

Technology evaluation is one of the key issues in discussions on the development of evaluation methods. This paper deals with some methods for the evaluation of new energy technologies, which were appraised by MAUT from various outlooks: economics, environment, and resource saving. MAUT is considered to be the proper method for evaluating the next generation energy technology, since it can evaluate alternatives that comprise basic criteria. This paper analyzes a priority order of 13 new energy technologies selected by groups of energy technology experts through two steps. Converted utility technology shows the highest value in economics.
