In modern society, there remain underprivileged communities that do not perform their own archival activities and documentation. Thus, many outside citizen archivists take the role of documenting the lives and activities of such communities on their behalf. However, ensuring the partyhood of these citizen archivists who are not part of the community proves to be problematic. This study aims to analyze how outside citizen archivists acquire partyhood in the process of documenting underprivileged communities through a case study labeled "Citizen Archivist Training Project" in Wanwol-dong, an area in Busan with a huge prostitution business. First, the process of acquiring partyhood in the outside citizen archivists' documentation of underprivileged communities was divided into three stages, following the literature review process. Second, this partyhood acquisition process was investigated stage by stage through interviews with participants in the case study in Wanwol-dong. Third and finally, following the investigation's findings, the attitude and position outside citizen archivists should have and take, respectively, in documenting underprivileged communities were identified.

The purpose of this study is to investigate the effect of the delayed resolution of cognitive conflict on middle school students' conceptual change in learning the concept of the action and reaction with cognitive conflict strategy. The subjects were divided into 3 groups according to the time in which teacher tried to resolve cognitive conflict: instant resolution group, 2-day delay resolution group, and 7-day delay resolution group. Pretest, just before test, posttest, and delayed posttest were examined to measure the degree of conceptual change. Delay resolution groups' students answered the questionnaire asking what they had done to resolve cognitive conflict during the period which had been delayed resolution of cognitive conflict. The results of this study were as follows. First, instant resolution group showed significantly more scientific conceptual change than delay resolution groups. Secondly, most of delay resolution groups' students who tried to resolve cognitive conflict interacted with their peers. Also, delayed resolution of cognitive conflict was not helpful to resolve cognitive conflict. Thirdly, in delay resolution groups, we found the tendency that students who spent more than 30 minutes trying to resolve cognitive conflict altered their preconceptions into scientific concepts more easily than the others did. According to the results of this study, instant resolution of cognitive conflict is more effective on scientific conceptual change than delayed resolution of cognitive conflict.
