This paper presents the perspective of the Structural Mechanics program of the Air Force Office of Scientific Research (AFOSR) on the damage assessment of structures for the period 2006-2009 when the author was serving as Program Manager at AFOSR. It is found that damage assessment of structures plays a very important role in assuring the safety and operational readiness of US Air Force fleet. The current fleet has many aging aircraft, which poses a considerable challenge for the operators and maintainers. The nondestructive evaluation technology is rather mature and able to detect damage with considerable reliability during the periodic maintenance inspections. The emerging structural health monitoring methodology has great potential, because it will use on-board damage detection sensors and systems, will be able to offer on-demand structural health bulletins. Considerable fundamental and applied research is still needed to enable the development, implementation, and dissemination of structural health monitoring technology.

Recently, there have been many changes in researches of mathematics education. There is a growing number of researchers who are interested in empirical researches. According to the these changes, there is also an emphasis on methodology of mathematics education. This means that many researchers try to conduct an research using scientific approach. Therefore, new types of research developing mathematics courses recently has evolved as follows: teaching experiment, hypothetical loaming trajectory, design science, developmental research. The aim of this study is to reflect on developmental research in RME and to induce desirable directions for developing our mathematics courses. In order to attain these purposes, the present paper reflects the philosophy of RME, aim, procedure, data collection, data analysis, and justification of developmental research with illustrating a exemplar Based on these reflections, it is discussed that it needs to construct the mathematics curriculum connecting theory and practice in mathematics education, to report the process of developing mathematics courses faithfully, and to develop real mathematics courses after conducting basic developmental researches in order to take scientific app- roaches for developing mathematics courses.

Objective: This study aimed to explore early childhood educators' anxiety regarding science education via Q-methodology. Methods: As the first step, 268 Q samples were collected from resources such as books and research papers related to science education for young children. Through five stages of excluding and modifying, a set of 33 Q statements was finalized. The P sample consisted of 40 early childhood educators and was based on educational levels, years of teaching experiences and types of centers. The collected data were analyzed using QUANL statistical program. Results: The results of this study indicate that science anxiety among early childhood educators are classified into four types, explaining 45.13% of the total variance. Conclusion: We conclude that early childhood educators' science anxiety stems from "preparing educational environment and materials," "instructional methods focused on process and scientific inquiry skills," "lack of understanding regarding early childhood science education," and "simple science avoidance."

This study provides a comprehensive survey of Post Keynesian economics. The global financial crisis 2008-2009 has triggered an important debate concerning economic theory, policy and methodology. The most important thing that this economic crisis has done for economics is that it revealed mainstream economics was wrong. Mainstream economics has been unable to offer clear answers for the crisis. The economic crisis, at the same time, brought about a crisis in the field of economics. This study suggests that economics needs to be altered into a new form that can explain the real world economy. In this paper, it is argued that Post Keynesian economics can be understood as the alternative economics. The paper begins with the vision and the origins of several Post Keynesian ideas, leading to an examination of certain features of the various groups, including their methodology and their approaches to uncertainty, their pricing theories and their growth theories. The focus, however, is on the stage reflected in Post Keynesian economics which is concerned with the conception of Lakatos's 'Scientific Research Programmes'. It is recognized that more research is necessary in order to complete the post keynesian economics as a standard science or as a progressive Scientific Research Programmes in economics.

The purpose of this paper is to review research articles on social computing and to provide the future directions of the study. A total of 51 articles published in social scientific journals from 2006 to 2010 are analysed by research theme, methodology, level of analysis, and application area. It is found that most of the studies are addressing blogs and mainly focusing on societal concepts rather than organizational concepts. The predominant methodology is field study at the individual level of analysis. We suggest that future researches on social computing need to address more various topics and application areas. Also diversity in terms of methodology and level of analysis is required.

The improvement and richness of research in a particular domain are fundamentally based on their own various research topics and scientific or systematic research methodology. Especially considering fisheries business administration as a branch of business administration, the interdisciplinary concept will be a important factor in the research of fisheries business administration. This study analyzes fisheries business administration research through bibliometric analysis and meta-analysis to examine meta-data including research trends, researcher characteristics, and keywords. The 225 source articles are all papers published from 1990 to 2006 in the Journal of Fisheries Business Administration Society of Korea. Comparing previous research from the 80s, the major areas of Korean fisheries business administration research have changed and the rate of co-researched papers has also increased. In keyword-based meta-analysis, the topics of recent research are well balanced and diversified but some structural and editorial problems still remain. The result from meta-data and bibliometric information gathered in this study will help create guidelines for carrying out further rigorous research and enhancing the quality of research in fisheries business administration.

The present study addresses isolation, optimization, partial purification, and characterization of a haloalkaline serine protease from a newly isolated haloarchaeal strain isolated from Wadi El Natrun in Egypt. We expected that a two-step sequential statistical approach (one variable at a time, followed by response surface methodology) might maximize the production of the haloalkaline serine protease. The enzyme was partially purified using Hiprep 16/60 sephacryl S-100 HR gel filtration column. Molecular identification revealed the newly isolated haloarchaeon to be Natrialba hulunbeirensis strain WNHS14. Among several tested physicochemical determinants, casamino acids, KCl, and NaCl showed the most significant effects on enzyme production as determined from results of the One-Variable-At-A-time (OVAT) study. The BoxBehnken design localized the optimal levels of the three key determinants; casamino acids, KCl, and NaCl to be 0.5% (w/v), 0.02% (w/v), and 15% (w/v), respectively, obtaining 62.9 U/ml as the maximal amount of protease produced after treatment at 40℃, and pH 9 for 9 days with 6-fold enhancement in yield. The enzyme was partially purified after size exclusion chromatography with specific activity, purification fold, and yield of 1282.63 U/mg, 8.9, and 23%, respectively. The enzyme showed its maximal activity at pH, temperature, and NaCl concentration optima of 10, 75℃, and 2 M, respectively. Phenylmethylsulfonyl fluoride (PMSF, 5 mM) completely inhibited enzyme activity.
