Two drug-enzyme conjugates of dexamethasone-subtilisin and dexamethasone-cellulase have been synthesized and characterized to study their drug-protein incorporation ratio, immunoreactivity, enzyme activity and stability and these studies proved that a variety of drug enzyme conjugates could also be synthesized and characterized.

Digital resources are widely used in our modern society. However, we are facing fundamental problems to maintain and preserve digital resources over time. Several standard methods for preserving digital resources have been developed and are in use. It is widely recognized that metadata is one of the most important components for digital archiving and preservation. There are many metadata standards for archiving and preservation of digital resources, where each standard has its own feature in accordance with its primary application. This means that each schema has to be appropriately selected and tailored in accordance with a particular application. And, in some cases, those schemas are combined in a larger frame work and container metadata such as the DCMI application framework and METS. There are many metadata standards for archives of digital resources. We used the following metadata standards in this study for the feature analysis me metadata standards - AGLS Metadata which is defined to improve search of both digital resources and non-digital resources, ISAD(G) which is a commonly used standard for archives, EAD which is well used for digital archives, OAIS which defines a metadata framework for preserving digital objects, and PREMIS which is designed primarily for preservation of digital resources. In addition, we extracted attributes from the decision tree defined for digital preservation process by Digital Preservation Coalition (DPC) and compared the set of attributes with these metadata standards. This paper shows the features of these metadata standards obtained through the feature analysis based on the records lifecycle model. The features are shown in a single frame work which makes it easy to relate the tasks in the lifecycle to metadata elements of these standards. As a result of the detailed analysis of the metadata elements, we clarified the features of the standards from the viewpoint of relationships between the elements and the lifecycle stages. Mapping between metadata schemas is often required in the long-term preservation process because different schemes are used in the records lifecycle. Therefore, it is crucial to build a unified framework to enhance interoperability of these schemes. This study presents a basis for the interoperability of different metadata schemas used in digital archiving and preservation.

The speech recording of the National Archives of Korea contains very important traces which represent modern times of Korea. But the way to be recorded by analogue is easily contaminated as time goes by. So it has to be digitalized for management and services. Consequently, restoration method of distorted speech is needed. We propose the four classes for each distortion kind and apply restoration algorithms for the cases of speech level, stationary noise and abrupt noise. As a result, speech volume adjusts to -26 dBov for only on the speech region and SNR improves above 10dB. Especially, conventional way to remove the noise is almost impossible because we need to listen to all of them but it can be more effective by adaptation of auto restoration algorithm.

This review article presents an assessment of trends in statistical methods and an evaluation of their appropriateness in articles published in the Archives of Plastic Surgery (APS) from 2012 to 2017. We reviewed 388 original articles published in APS between 2012 and 2017. We categorized the articles that used statistical methods according to the type of statistical method, the number of statistical methods, and the type of statistical software used. We checked whether there were errors in the description of statistical methods and results. A total of 230 articles (59.3%) published in APS between 2012 and 2017 used one or more statistical method. Within these articles, there were 261 applications of statistical methods with continuous or ordinal outcomes, and 139 applications of statistical methods with categorical outcome. The Pearson chi-square test (17.4%) and the Mann-Whitney U test (14.4%) were the most frequently used methods. Errors in describing statistical methods and results were found in 133 of the 230 articles (57.8%). Inadequate description of P-values was the most common error (39.1%). Among the 230 articles that used statistical methods, 71.7% provided details about the statistical software programs used for the analyses. SPSS was predominantly used in the articles that presented statistical analyses. We found that the use of statistical methods in APS has increased over the last 6 years. It seems that researchers have been paying more attention to the proper use of statistics in recent years. It is expected that these positive trends will continue in APS.

This paper aims to introduce the background history and development of records management in brief prior to and after the 1990s based on the records life cycle. This paper also explains the development of electronic document imaging systems and shifts to ERM systemsin the 1990s. The paper explains functional requirements in archival management and software application standards suggested by the industry of electronic records management. The paper concludes with providing problems and issues associated with software design in electronic records management for further development.

급변하는 정보화시대 속에서 우리가 잊고 있는 중대한 사실이 있다. 이는 우리가 많은 양의 정보를 가장 빠르고 작고 편리하게 담고자 치중하고 있는 지금, 그 주체가 되는 기록물, 즉 종이에 적혀있는 과거의 역사는 조금씩 우리 곁에서 사라져 가고 있다는 사실이다. 다시말하자면, 우리가 막대한 예산을 들여 이 기록물을 보존하는 목적으로 다른 매체로 전환시키는데 총력을 기울이면서도, 실제로 보존 대상인 이 기록물들에 대해서는 예산부족을 핑계로 삼아 등한시하고 있는 것이다. 기록물의 보존은 과거에도 중요하게 여겨졌고, 현재와 미래에도 계속 중요하게 여겨질 것이다. 그럼으로 우리는 과거의 기록이라는 메시지를 우리의 선조들로부터 전해 받아 우리의 다음세대에게 전해주는 메신저에 불과하므로 이 메신저의 역할에 대하여 정확하게 알아야 할 것이다. 또한 우리가 전해 받은 과거의 유물로 그대로 물어주기 위해서는 우리가 이 시대에 할 수 있는 최선의 일은 그 원형을 잘 보존시키는 일이다. 이러한 기록물의 소실은 그 기록물에 적혀 있는 과거 역사의 소실을 뜻한다. 따라서 앞으로의 보존과학은 과거에 대한 우리의 탐험을 뒷받침할 많은 정보들을 제시하여 줄 것이며 이러한 정보들이 체계적으로 분류되어 정리될 때 한국 종이 기록물의 보존 복원이 발전을 거듭할 것이다.
