본 연구는 대학도서관 경영평가를 위한 표준지표 및 평가방법의 개발을 목표로, 다양한 이해관계자들의 의견 수집 및 합의를 통하여 평가체계 안을 제안하였다. 이를 위해 우선 대학도서관 평가의 목적과 요구조건을 살펴보고, 다수의 이해관계자의 의견에 기초하여, 심층면담, 설문조사, 포커스 그룹 등을 이용한 다단계 합의의 방법으로 평가지표를 추출하였으며, 이의 구성 및 배점체계 등을 개발하였다. 전반적 평가체계는 과정적 접근을 큰 틀로 하여, 내부적/기능적인 과정 범주와, 외부적/서비스중심적인 자원 및 결과 범주를 고려하였으며, 범주들 간의 중요도의 균형 속에서 조사 분석 결과의 항목별 중요성에 따라 배점체계를 구축하였다. 더불어 평가방법 및 연차별 평가개선 로드맵을 제시하였다. 평가체계의 개발을 통해 본 연구는 대학도서관 평가활동에 기여할 뿐 아니라 대학도서관의 성과요소 및 예측변인들에 대한 논의의 활성화에도 기여할 수 있기를 기대한다.

In complex decision making such as ill-defined system, one of the main problem is how to treat ambiguous aspect of the decision making. According to the complexity and ambiguity of the objective systems, many types of evaluation attributes are necessary for the rational decision and the relationship among the attributes become complex and fuzzy. Fuzzy integral is very effective to evalute the complex system with interaction between attributes but how to save the evaluation efforts in the decision making process of grading the membership of the objects or alternative is the problem to be tackled. Because the more object there are to evaluate, the number of decisions to made increase exponentially. Therefore, this paper aimes to propose a new evaluation algorithm based on fuzzy integral which can save the evaluator's efforts in decision making process. The proposed algorithm is constructed as follows : First, compose the fuzzy measure by introducing AHP(Analytical Hierachy Process) & mutual interaction coefficient. Second, generate fuzzy measure value of monotone family set for calculating the fuzzy integral. The effectiveness of the proposed algorithm is investigated through the example and sensitivity of interaction coefficient is illustrated.

In this paper, to evaluate ease of exchange of subassembly considering module, it needs to analyze structure and function of subassembly, assembly and disassembly process. Exchange process of module can be divided into pre-process and in-process, and determination factors of exchange process are defined by analyzing characteristics of assembly and disassembly process. Based on the analysis of characteristics for structure and function of subassembly, influential factors of module can be proposed. Considered the interrelationship between determination factors of ease of exchange and influencing factors of module, ease of exchange can be evaluated.

The seismic performance evaluation and retrofit process are very important for old bridge. If the result is not appropriate, a retrofit process requires. Among the various retrofit methods, this paper selects a seismic isolator and evaluates a seismic performance of bridge. In case of applied seismic isolators to bridge, it proved that seismic capacity is increased by isolators A period of bridge is increased, and a seismic response is decreased. A method of evaluation is capacity spectrum method. By means of a graphical procedure, capacity spectrum estimates a performance level of structure by comparing the capacity of structure with the demand of earthquake ground motion on the structure. The objective of this study is to compare a seismic performance of a non-seismic designed bridge and seismic isolated bridge and to verify a effect of seismic isolator

Evaluation of bond strength of a fire-damaged reinforced concrete structure for determining whether to reuse, reinforced, or abandon the structure is very important. Recently, calculating method for changes in bond strength of rebars is proposed by C. Chiang. The equation is relating the ratio of residual bond strength, R, to temperature, T, and exposure time, t. This study presented and verified a general process for evaluating damage to bond strength of RC structure arising from high temperature.

The weapon systems development has some distinct characteristics in that a big size of government budget (derived from national tax) has been expended frequently and the completion of the development projects seems to take long. Thus, the impact of the potential changes in the required operational capability on the development activities can induce some type of project risks. As such, proper management of project risk has been one of crucial subjects in the weapon systems development. Although a variety of methods can be considered, an approach based on the test and evaluation (T&E) process has been selected in this paper in order to appropriately handle those potential risks. In the study of the underlying T&E process, the safety consideration (for instance, explosiveness) of weapon systems is also included. To achieve the objective of the paper, a step-by-step procedure is first presented in the analysis of the T&E process. Then, to pursue some enhancement on the process, a set of necessary and useful activities are added in terms of risk and safety management. The resultant process is further analyzed and tailored based on a design structure matrix method. The case study of a tank development is also discussed.

Since product design strongly depends on the experience and ability of the designers, and a long lead time is required for the product design stage, introducing a support system related to this experience and ability is an effective technique to reduce the lead time. In this paper, an information system is developed to support the development of engineering mechanisms with the evaluation of the assembly process on the basis of the abstract functions required for new products. The developed system is based on a database system involving the following data structure: (1) a hierarchical structure related to information about the product functions, (2) the relationship between the parts and engineering functions and/or mechanisms of products, and (3) the relationship between the parts and manufacturing characteristics. The system stores the relationships between the product functions, structure of parts, and assembly characteristics. This information can then be interactively retrieved using the data structure described in (1), (2), and (3). A procedure for designing new products is proposed that involves using the information about existing products. This paper presents the characteristics of the proposed procedure and the developed information system. In addition, a case study of the redesign of a simple structured robot by using the proposed procedure is discussed.

The frameworks for evaluation of national R&D programs reflect their various political and administrative cultures(Gibbons & Georghiou, 1987), and the structure of national R&D system. In this research the core research questions are : what is god evaluation\ulcorner What is being evaluated, by whom, by which criteria, for whom and what purpose\ulcorner In order to examine these general aims and answer these questions, in detail several objectives can be proposed on the process of this research. In this research, the national R&D programs will be considered in terms of the interface between evaluation and the wider policy-making process. The programs for case study are the Alvey program(UK), the Advanced Technology Program (US) and the Framework program(EU) . One of the characteristics of these programs is the well established evaluation systems they have. From the comparative analysis, we can withdraw some useful implication for Korean evaluation practice for national R&D programs. Evaluation system is social process and the way in which it is organized is critical to its outcome.
