  • 문서 유형의 전자기록물 장기보존을 위해 국가기록원에서는 PDF/A-1을 보존포맷으로 선정하였고 문서보존포맷으로 명명하여 공공표준으로 제정하였다. 문서 중심의 하나의 보존포맷인 PDF/A-1를 선택할 수 밖에 없기 때문에, IT 발전과 업무 변화에 따라 실제 업무에 적용할 수 있거나 적용해야만 하는 다양한 전자파일 포맷들을 활용하는데 제약을 주고 있으며, 문서 이외에 다른 유형의 전자기록물(행정정보데이터세트, 시청각기록물, 웹기록물 등)에는 적용되기 어렵다. 그러므로 전자기록물의 보존포맷을 다양화할 수 있는 방안이 필요하다. 본 논문에서는, 우선 전자기록물의 보존포맷을 다양화할 수 있는 보존포맷 선정체계를 제시한다. 또한, 보존포맷을 선정할 때, 모든 전자기록물에 공통으로 적용되는 기준인 공통기준 및 평가방식, 그리고 전자기록물 유형별로 적용되는 고유기준을 도출하기 위한 방법론을 제안하고자 한다.

  • Various environmental ecosystems are valuable sources for microbial ecology studies, and their analyses using recently developed molecular ecological approaches have drawn significant attention within the scientific community. Changes in the microbial community structures due to various anthropogenic activities can be evaluated by various culture-independent methods e.g. ARISA, DGGE, SSCP, T-RFLP, clone library, pyrosequencing, etc. Direct amplification of total community DNA and amplification of most conserved region (16S rRNA) are common initial steps, followed by either fingerprinting or sequencing analysis. Fingerprinting methods are relatively quicker than sequencing analysis in evaluating the changes in the microbial community. Being an efficient, sensitive and time- and cost effective method, T-RFLP is regularly used by many researchers to access the microbial diversity. Among various fingerprinting methods T-RFLP became an important tool in studying the microbial community structure because of its sensitivity and reproducibility. In this present review, we will discuss the important developments in T-RFLP methodology to distinguish the total microbial diversity and community composition in the various ecosystems.

  • Ductile fracture is one of the most common failure modes of steel beam-to-column connections in moment resisting frames. Most proposed evaluation methods of the plastic deformation capacity of a beam until ductile fracture are based on steel beam tests, where the material's yield strength/ratio, the beam's moment gradient, and loading history are the most important parameters. It is impossible and unpractical to cover all these parameters in real tests. Therefore, a new attempt to evaluate a beam's plastic deformation capacity through analysis is introduced in this paper. Another important issue is about the loading histories. Recent years, the effect on the structural component under long-duration ground motion has drawn great attentions. Steel beams tends to experience a large number of loading cycles with small amplitudes during long-duration earthquakes. However, current research often focuses on the beam's behavior under standard incremental loading protocols recommended by respective countries. In this paper, the plastic deformation capacity of steel beams subjected to long duration ground motions was evaluated through analytical methodology.

  • Purpose: The purpose of this study was to identify trends in intervention studies on childhood obesity in Korea. Methods: From 1996, when the first research paper on childhood obesity intervention was published, to 2015, 192 published papers were analyzed using descriptive statistics. Results: The number of studies increased sharply between 1996 and 2007, but declined slightly from then. The majority of studies involved only children as intervention participants. Most were elementary students, and overweight and obese children. Exercise therapy was the most common type of intervention. Parental participation was found in 35 studies, while teacher's participation was found in only one study. In many studies physiological indicators were used as measurement variables, but follow-up was done in only 10 studies. Finally, only a few studies applied a conceptual framework, while a quasi-experimental research design was used for most studies. Conclusion: Examination of trends in intervention studies on childhood obesity in Korea, shows there has been a quantitative increase but not enough improvement in terms of the quality of interventions. Findings in the present study suggest that it is necessary to seek diversity in terms of study participants, interventions and evaluation method along with quality improvement in research methodology.

  • The exact load measurements for the mechanical parts of a wind turbine are important step both fur the evaluation of a specific wind turbine design and for a certification process. A common method for a mechanical load measurement is using a strain gauge sensing. Two main problems ought to be answered in order for this method to be applied to the wind turbine project. These are strain gauge calibration and non-contact signal transmission from the strain gauge output to a load monitoring system. This paper suggests reliable solutions fer these two problems. A Bluetooth, a short range wireless data communication technology, is used to solve the second problem. The first one, the strain gauge calibration methodology for a load measurement in a wind turbine application, is fully explained in this paper. Various mechanical loadings for a strain gauge calibration in a wind turbine load measurement are introduced and analyzed. Initial experimental results which are obtained from a 1 kW small size wind turbine are analyzed, and the uncertainty problem in estimating mechanical loads using a calibration matrix is fully covered in this paper.

  • Purpose: The purpose of this study was to identify trends in health-related interventions on children attending Community Child Care (CCC) centers, which are part of a health policy to provide after-school care for vulnerable children in South Korea. Methods: From 2007, 109 papers were analyzed using the scoping study method. Results: The number of studies increased steadily between 2007 and 2016. Most studies were based on the social sciences, and the participants were mainly elementary school students. Psychological and social interventions were the most common types of interventions with socio-psychological indicators as measurements. In addition, only a few studies had a clearly defined conceptual framework. The majority of studies did not explicitly indicate that they followed ethical considerations. Conclusion: It is necessary to develop health-related interventions for children attending CCC centers using diverse subjects, types, and evaluation methods, along with improvements in the quality of research methodology. Furthermore, it is essential to clearly articulate and implement ethical considerations in research targeting vulnerable children.

  • Purpose - It seems common sense that corporate social responsibility (CSR) is a key driver of business sustainability. Nevertheless, there has been little research on the performance of socially responsible activities, including economic and environmentally responsibility activities, in internationally diversified firms. Design/methodology - The purpose of this study was to evaluate the effects of CSR activities on management performance. For this evaluation, an empirical analysis was conducted with total of 2,520 cases, selected from companies listed on the Korea Composite Stock Price Index market for six years from 2013 to 2018. As proxies for management performance, financial data such as a total asset net profit ratio and a total asset operating ratio were used. A multivariate regression analysis was conducted to test hypotheses. Findings - The results of this analysis indicated that firms in the CSR outstanding group were ranked significantly higher than other groups in management performance. In addition, CSR activities of internationally diversified firms positively influenced the total asset net profit ratio and total asset operating ratio. Originality/value - The results suggest that the CSR activities of these firms can play a significant role in enhancing management performance in the economic status of Korea, where the degree of export dependency is high.
