이 글은 전자잡지의 선정, 예산, 정책결정, 장서평가, 보존 등 전자잡지에 관한 장서관리문제를 소개 분석하고 있다. 전자잡지와 관련한 직원과 예산이 주제별 접근방식이나 형태별 접근방식에 따라, 또는 이 두 접근방식을 병행하여 조직될 수 있다고 주장하고 있다. 전자잡지는 인쇄형태 잡지와 마찬가지로 자료식별, 평가, 선정이라는 3단계과정을 거쳐 선정된다. 전자잡지는 인쇄형태잡지에 적용되는 전통적 기준뿐만 아니라 또 다른 기준이 추가로 적용된다. 이 글은 전자잡지의 구독취소와 제적을 언급하고 있지 않지만, 그 중요성은 증가할 것이다. 잡지의 소유권보다는 이용가능성과 접근가능성에 중점을 둔 새로운 이용자위주 평가 방법기법에 대한 요구가 일고 있다.

The fundamental small-signal modeling of lithium-ion (Li-ion) batteries and a parameter evaluation approach are investigated in this study to describe the dynamic behaviors of small signals accurately. The main contributions of the study are as follows. 1) The operational principle of the small signals of Li-ion batteries is revealed to prove that the sinusoidal voltage response of a Li-ion battery is a result of a sinusoidal current stimulation of an AC small signals. 2) Three small-signal measurement conditions, namely stability, causality, and linearity, are proved mathematically proven to ensure the validity of the frequency response of the experimental data. 3) Based on the internal structure and electrochemical operational mechanism of the battery, an AC small-signal model is established to depict its dynamic behaviors. 4) A classical least-squares curve fitting for experimental data, referred as Levy's method, are introduced and developed to identify small-signal model parameters. Experimental and simulation results show that the measured frequency response data fit well within reading accuracy of the simulated results; moreover, the small-signal parameters identified by Levy's method are remarkably close to the measured parameters. Although the fundamental and parameter evaluation approaches are discussed for Li-ion batteries, they are expected to be applicable for other batteries.

사회가 발전함에 따라 연구개발의 필요성이 부각되면서 이를 위한 기술정보서비스의 제공과 이에 대한 평가의 중요성 또한 강조되고 있다. 기술정보서비스의 경제성에 대한 평가는 정보가치의 평가와 마찬가지로 매우 다양하며 또한 기술정보서비스의 하부구조에 의해서 영향을 받기도 한다. 그러므로 기술정보서비스의 생산성 즉 경제성에 대한 평가는 보다 체계적이고 복합적인 접근을 바탕으로 이루어져야 한다.

Evaluation methods are employed in environmental impact assessment to choose between different project site, to determine the required measures to compensate impact and to decide whether the environmental impacts are more important than the social or economic effects of a project. The main obstacles that restrict use of quantitative evaluation method are a Lack of knowledge about the environmental effects (e.g. if impacts on wildlife or landscape amenities are predicted) and the relative importance of economic and social issues compared with nature conservation stability of ecosystem or landscape beauty. In Germany, the most common method for site planning is the "ecological risk analysis". It is a kind of multi-criteria-decision-method based on quantitative and qualitative description and ordinal ranking. The various kinds of "ecological balancing methods" that are more recently developed (within the last decade) to quantify the required amount for compensatory measures instead often use cardinal figures to express the value of ecosystems, the intensity of impacts, the need for additional measures to compensate for long recuperative periods when restoring ecosystems and so on. There are still only a view attempts to quantify decisions between environmental and socio-economic issues. Multicriteria-analysis as well as cost-benifit-analysis was used. Some new approaches which are still in a preliminary status are based on contingent valuation and on calculations for compensatory payments (instead of compensatory measures).

Software testing cost can be reduced if the process of testing is automated. However, the test data generation task is still performed mostly by hand although numerous theoretical works have been proposed to automate the process of generating test data and even commercial test data generators appeared on the market. Despite prolific research reports, few attempts have been made to evaluate and characterize those techniques. Therefore, a lot of works have been proposed to automate the process of generating test data. However, there is no overall evaluation and comparison of these techniques. Evaluation and comparison of existing techniques are useful for choosing appropriate approaches for particular applications, and also provide insights into the strengths and weaknesses of current methods. This paper conducts experiments on four representative test data generation techniques and discusses the experimental results. The results of the experiments show that the genetic algorithm (GA)-based test data generation performs the best. However, there are still some weaknesses in the GA-based method. Therefore, we modify the standard GA-based method to cope with these weaknesses. The experiments are carried out to compare the standard GA-based method and two modified versions of the GA-based method.

Objectives: This paper aims to describe a public health planning model, Mobilizing for Action through Planning and Partnership(MAPP), and to discuss its application in Korea with a specific focus on the Local Public Health System (LPHS) component of MAPP. Methods: Literature content review was performed on research papers on MAPP development and application, MAPP handbook and guides, the guidelines for the 5th Phase Community Health Plan, and a research report on public health center evaluation system. Results: MAPP has been applied to public health planning (the 5th Phase Community Health Plan) and a performance evaluation system for public health center in Korea. The current application is limited to the early stages of the MAPP. Limited or partial application affects the integrity of the model. Follow-through should be strengthened especially for evaluation planning. Conclusion: Systems thinking approaches should be considered for the development of LPHS and strengthening logical and practical linkage between planning and evaluation of community health planning.

Community-Based Participatory Research(CBPR) has gained attention as a public health approach to develop community health interventions to address health disparities in recognition of the community relevance of specific health issues associated with social determinants of health. It emphasizes community involvement in equal partnership with researchers and public health professionals to address community-identified needs. The characteristics and principles of CBPR discussed in this paper highlight participatory nature, capacity development, partnership building, and process-orientation of CBPR. A 6-step process model for community empowerment is then introduced as a CBPR operationalization strategy. Mixed methods research approaches are valuable in CBPR as well as process evaluation. For the application of CBPR in Korean contexts, the Diffusion of Innovation theory is suggested as a theoretical framework for implementation. Building public health partnerships between public and private sectors to create partnership synergy is a necessary condition for successful CBPR for health promotion in Korea. Accompanying critical factors for the CBPR application include: common understanding of CBPR and its values, establishment of the definition of 'community,' 'community-based' and 'participation' in community health, development of accommodating research infrastructure for CBPR, recognition of the importance of program evaluation (particularly process evaluation), and training CBPR specialists.
