The most important task in acquiring the weapon system is to determine the required performance and to test & evaluate it. The importance of the weapon system by ROC (Required Operational Capability) is not considered, and system development and test evaluation are carried out. In addition, technical incidental performance is tested on the same basis as ROC in the test evaluation and determined according to the result. Development test and evaluation that evaluates technical ability is very important, but development agency is supervised and performed. In this paper, we propose a method to give weights considering the importance of ROC, a technical incidental performance determination and test procedure, and a improvement plan for the development and operational test & evaluation.

Dweller's safety is one of the most important factors for the evaluation of building performance. The process of conventional safety design which is normally performed by the codes and designer's experiences is not enough to check the whole possibilities of unexpected accidents in the built environment. It means that the dwellers might be always exposed by the dangerous situation which should have been removed in the architectural design process. In order to solve this problem, this study intends to introduce a rule-based performance evaluation technology based on BIM(Building Information Modeling). The proposed technology focuses on the real time evaluation of dweller's safety in the ordinary life in the designed building alternatives and uses a commercial BIM tool as a design and evaluation platform.

Many of the studies of visual attention that are currently underway are seeking ways to make application systems that can be used in practice, and obtained good results using not only simulated images but also real-world images. However, despite that previous studies of selective visual attention are models intended to implement the human vision, few experiments verified the models with actual humans and there is no standardized data nor standardized experimental method for actual images. Therefore, in this paper, we propose a new performance evaluation techniques necessary for evaluation of visual attention systems. We developed an evaluation method for evaluating the performance of the visual attention system through comparison with the results of the human experiments on visual attention. Human experiments on visual attention is an experiments where human beings are instinctively aware of the unconscious when images are given to humans. So it can be useful for evaluating performance of the bottom-up attention system. Also we propose a new selective attention system that guides the user to effectively detect ROI regions by using spatial and temporal features adaptively selected according to the input image. We evaluated the performance of proposed visual attention system through the developed performance evaluation method, and we could confirm that the results of the visual attention system are similar to those of the human visual attention.

Nonlinear static analysis and preliminary evaluation were performed in this study to evaluate the seismic performance of unreinforced masonry buildings subjected to various soil conditions based on the revised Korean Building Code. Preliminary evaluation scores and nonlinear static analyses indicated that all buildings were susceptible to collapse and did not reach their target performance. Therefore, retrofit of those building models was carried out through a systematic procedure to determine areas to be strengthened. It was possible to make most building models satisfy performance objectives through the reinforcement alone of damaged external shear walls. However, the application of a preliminary evaluation procedure to retrofit design was found to be too conservative because all the retrofitted building models verified with nonlinear static analysis failed to satisfy performance objectives. Therefore, it is possible to economically retrofit unreinforced masonry buildings through the fortification of external walls if a simple evaluation procedure that can efficiently specify vulnerable parts is developed.

There has been the migration to a performance-based approach in many areas which include transition planning at global, regional and local levels, performance-based navigation and safety management. Achieving continuous success of Air Traffic Management (ATM) systems would require a performance-based approach to raise productivity and efficiency of it through performance measurements and reviews. This paper considers establishment planning of performance measurement and evaluation system for ATM. Related to key performance areas proposed by International Civil Aviation Organization, performance indicators and metrics which could be used to measure and evaluate ATM performance are presented. Also, organizational system and operational planning for efficient operation of ATM are presented.

2019년 개정된 시설물 안전과 유지관리 세부지침을 보면, 기존의 안전성 중심의 시설물 평가에서 내구성과 사용성을 추가한 성능평가로 확대된 바 있다. 이러한 확대는 전 세계적으로 이슈화되고 있는 시설물의 고령화와 시설 이용측면을 반영한 점이기는 하나 실제로 이러한 시설물 평가가 유지관리와 관계된 보수보강과 연계되기 때문에 각 세부성능 간의 상관관계 및 목표 성능의 선정과 연계된 성능보강시 우선순위 결정 등 많은 후속연구가 필요하다. 이 연구에서는 국내 도로시설에 설치된 옹벽을 중심으로 기존의 시설물 평가이력에 대한 분석을 통해 우선적으로 개정된 성능평가에서 적절한 목표 성능을 제시하였다. 또한, 실제 2개의 옹벽에 대해 평가를 수행하고 목표성능의 적절성 여부를 검토하였다. 그리고, 안전성과 내구성만으로 구성된 옹벽의 성능평가에 사용성 부분을 추가할 수 있는 세부 지표를 제시하였다.

In order to analyze the organizational performance of government-funded research institutes, four independent variables (organization size, organization age, evaluation system, organization location) and goal ambiguity were empirically analyzed. Although there are existing studies on institutional evaluation, which is the organizational performance of government-funded research institutes, there are differences in research in that it is an empirical analysis analyzed from the perspective of goal ambiguity and that the evaluation system, which is the specificity of institutional evaluation, is included in the analysis. As a result of the analysis, organizational location was the only independent variable that had a direct significant effect on organizational performance, and goal ambiguity showed a significant mediating effect for all independent variables. This indicates that goal ambiguity plays an important role in the organizational performance of government-funded research institutes, and to reduce this, increase the size of the organization, pay attention to establishment of the organization for organizational age, and that it is desirable to have an independent research group in the government department for the organization location. In addition, it was supported that the improvement effect of the evaluation system is proceeding in a desirable direction in terms of goal ambiguity.

In this paper, we deal with the performance evaluation method of user identification and user tracking for intelligent robots using face images. This paper shows general approaches for standard evaluation methods to improve intelligent robot systems as well as their algorithms. The evaluation methods proposed in this paper can be combined with the evaluation methods for detection algorithms of face region and facial components to measure the overall performance of face recognition in intelligent robots.

Background : Performance evaluation of medical care providers has become more important than before in Korea. Especially in university hospitals, job contents of medical staffs are so complicated that evaluation is not easily performed. In addition, in order that the feedback of evaluation be successful, acceptance of staffs to be evaluated is essential. This study is aimed at the development of items for evaluation and weighting of each item in one university hospital, and clustering departments by different weight given by medical staffs. Methods : Through resource group meeting. performance items were listed up by categories of education, research, medical services, and other activities in and out of the hospital. For each item, all the medical staffs were asked how important they thought, compared with publishing one original article. By factor analysis, the items in each category were grouped into a few subgroups. In turn, cluster analysis was done for the purpose of grouping departments by priority the medical staffs gave. Results and Conclusion : Among five major categories, medical staffs regard education, research, and medical services more important than other activities in and out of the hospital. Five categories consisted of two or three components. Departments in hospital were grouped into three. However, characteristics of each group was not clearly delineated. This result suggests that more comprehensive tool should be developed and applied in the process of performance evaluation in university hospitals.
