Unlike in the past, a new paradigm has been presented which the use of records is much more important than the preservation of those in the present. It will be necessary for users to signalizes the value of records and to make themselves easily accessible to records in order that records should be more effectively used. To meet the needs of the times, it is the very 'Contents' that starts to attract public attention. National Archives in England produces and provides contents utilizing multi-media by using digital technology on various sorts of archives which England has. In addition to England, Asian Historical Records center in Japan in Japan makes Archival Contents Service reflecting users' needs and continues to update the latest contents. What is more, National Archives of Korea has recently promoted the introduction of digital archive by the change of archival paradigm in records management, and it is giving an impetus to the development of contents in the digital archive. In fact, it is crucial to keep as many contents as possible and to give service to public, but it will not be possible to get positive response from public and to offer much higher level of archival information service until the quality of contents is highly improved. Accordingly, this manuscript analyzed the feature and type of contents which National Archives of Korea provides with cases of both TNA in England and Asian Historical Records center in Japan, each of which has different characteristics. Also, it dealt with several methods of the usage of contents in those organizations. Furthermore, this study explained what kind of contents and feedback are given to users. Moreover, it divided the components of contents of three institutions as mentioned into three by information provided and evaluated the quality of contents by establishing the details of contents. In addition, there were implications for archives with regard to reference for building contents.

This study sought to find out the impact of conflicts in social welfare organizations on job performance and to find out the effects of controlling participatory decision-making in their relationships. To that end, a survey was conducted on workers at social welfare centers in Seoul, Gyeonggi Province and Chungcheong Province, and 360 copies were finally used for analysis and Correlation and hierarchical regression and statistical significance analysis of the adjustment effects were performed. As a result, conflicts within the organization, job performance, and participatory decision-making showed a negative correlation, and as participatory decision-making in the relationship between conflict within the organization and job performance showed a controlled effect, the impact of conflicts within the organization on job performance was reduced. These results suggest that participatory decision-making can alleviate conflicts within an organization and at the same time increase job performance. Based on this, the following suggestions were proposed: They include conflict management strategies in the guidelines for social welfare subjects, establish guidelines for conflict management, provide training for workers, engage workers in employee evaluation and compensation system development, and operate permanent organizations such as the Conflict Handling Committee after investigating conflicts within social welfare organizations.

The purpose of this study was to research the effects of Korean beginner learners' perception of vocabulary learning and comparison of vocabulary learning methods between the use of vocabulary application Classcard and rote learning with writing. This experiment was conducted by 24 beginner Korean learners who were at the 1st and 2nd level in Institute of Korean Language of D University. These students were dividing into 2 groups for the test - 12 in the control group and 12 in the experimental group. They took the vocabulary tests which were designed for examining the differences between before and after learning. Study results showed that vocabulary learning using the application Classcard significantly improved learners' vocabulary scores which were statistically significant. These results demonstrated that the method using Classcard has a greater learning effect than the method of rote learning with writing. Furthermore, the survey showed that learners did not feel uncomfortable in learning vocabulary using the application Classcard, and they thought it was one of the ways to learn vocabulary easily, which means that vocabulary learning using this application has a positive effect on learners' learning achievement. This study is significant in that it suggested a vocabulary learning method that can increase learners' interest and vocabulary by proving the effect of vocabulary learning using applications.

e-러닝의 활용도와 역할이 커져 가면서, 온톨로지(Ontology)나 컨셉맵(Concept Map)을 이용하여 e-러닝의 학습효과를 높이는 방안들이 연구되고 있다. 그러나 아직까지 e-러닝에 온톨로지나 컨셉맵 개념을 적용한 연구 사례는 미미한 수준이며, 이들간의 연계에 대한 고려 없이 별개의 대상으로 다루어져 왔다. 본 연구는 온톨로지와 컨셉맵의 상호 연관 관계와 각각의 장점들을 분석하여 학습에 있어서 시너지(Synergy)를 가져올 수 있는 새로운 e-러닝 시스템 구축 방안을 제안한다. 제안 시스템에서 온톨로지와 컨셉맵 간의 연계는 컨셉맵 에이전트에 의해 이루어진다. 컨셉맵 에이전트는 학습자의 수준이나 관심영역(주제와 범위)에 맞게 온톨로지로부터 추출한 학습 콘텐츠를 재구성해 준다. 학습자는 제안 시스템의 사용자 인터페이스를 통해 자신이 이해하고 있는 지식을 컨셉맵 형태로 표현할 수 있고, 컨셉맵 에이전트에게 요청하여 제공 받은 모범답안 컨셉맵과 자신이 표현한 컨셉맵을 비교하여 학습자가 스스로 자기 평가를 할 수 있다. 본 e-러닝 시스템이 제공하는 이러한 새로운 형태의 학습 환경은 학습자가 학습 지식에 대해 보다 체계적으로 접근하여 효과적으로 학습할 수 있게 해준다. 또한, 학습에 있어서 컨셉맵을 이용하므로 학습 형태의 특성상 보다 원천적으로 암기 위주의 학습에서 탈피하여 구성주의적인 학습을 가능하게 한다.
