In this study, four gifted students in the second year of middle school at Gifted Education Center of the National University in Jeollanam-do were surveyed students' perceptions of the effectiveness of science class using science writing heuristic in terms of metacognition and the goals of the 2015 revised science curriculum. Through questionnaires and interviews with gifted science students, science gifted students recognized that the science class using science writing heuristic had a positive effect on the four subdomains (planning, monitoring, control, and evaluation) of metacognition. For this reason, the science gifted students presented self-directed experience in designing experiments, continually checking the collected experimental data, feedback process, and reflecting experience in preparing conclusions. Science gifted students recognized that science class using science writing heuristic had a positive effect on the goals of the 2015 revised science curriculum(attitudes, inquiry, knowledge, Science·Technology·Society(STS), and the enjoyment and usefulness of science learning) that correspond to through inquiry science writing lessons. For this reason, the science gifted students presented self-directed inquiry experiences, continual inquiry experiences on the same subject, thinking process at each stage of inquiry, learning experiences through inquiry, experience of the whole inquiry process, and inquiry of phenomena closely related to real life. Therefore, for the effective science class, it is necessary to apply the characteristics of science class using science writing heuristic which is responded by science gifted students to general science class as well as science gifted class later.

This study aimed to explore the patterns of college students' dialogic argumentation in the context of nanotechnology issues, and to compare these patterns based on their idiocentrism and allocentrism. Nanotechnology represents the characteristics of socioscientific issues in that it is widely used in various fields, but at the same time, it includes the likelihood of negative effects. 33 college students who enrolled in science-related course participated in this study. Participants were divided into idiocentric groups and allocentric groups based on the INDCOL scores, and they participated in group discussions on nanotechnology. All discussions were audiotaped and analyzed using the framework of discourse clusters and schemes. Results showed that participating students engaged in dialogic argumentation with the process of exchanging of individual perspectives, exploration of different perspectives, and coordination and negotiation; specifically, they spent most of their time in exploring different values and perspectives regarding nanotechnology. Results also indicated the differences in discourse clusters and discourse schemes between idiocentric and allocentric groups. Allocentric groups more often negotiated to settle on a group decision than idiocentric groups did, and discourse schemes in their negotiation process were slightly different from the ones in idiocentric groups.

This study is to explore how the bondage of street homeless is made and what it implies. In order to do so, this study does participation-observation for the life of the homeless on the street and drop-in-center according to the ethno-graphic research tradition. Starting from the August of 2005, during the period of six months, we did a field study on the actual conditions of facilities for the homeless in the major parts in Seoul and collected the interview data through the interview-in-depth with 8 homeless people. Following the data-analysis procedures of Spradley(1979), we identified the main domains related to the factors for the bonding of street homeless. These domains show us how the homeless people who were left in the whole new world of homelessness just manage to tide over the crisis of identity and survival. The bondage of street homeless in the situation of street homelessness has been shown to have these following meanings: (1) the cultural significance as their second home, (2) the meaning of an alternative group to be admitted, (3) the maintenance of self-identity by way of distinction in the group. According to these, the self-identity of homeless is dual and, therefore, the meaning and interpretation of their relationship is also dual. This dualistic attitude comes from the process in which the homeless acquire the alliance-resource for the very survival and self-existence. The results of this study confirm that the homeless suffer from the lack of true relationship as well as resources. This study suggests that the supporting policies and services for the street homeless should be achieved qualitatively and integrated under a long range plan.

This study, based on the research on the history of life, aimed to recompose and analyze into what life progressive structure the life experience by the mentally ill, after the onslaught of the disease, developed in a bid to understand the risk progress in the mentally ill's life, and to determine what contributed to the current stabilized recovery and adjustment. Five mentally ill persons participated in the study, and Sch$\ddot{u}$tze's narrative interview was used to gather data. The gathered data were analyzed according to Sch$\ddot{u}$tze's process structure of life. The interviewees' life experiences were chronologically organized as understood, and significant stories were recomposed that not only brought about changes but also helped overcome their disabilities in the process of treatment and rehabilitation after the onslaught of the disease. As a result, their experiences were recomposed into the stage of onslaught of the mental illness and confusion, and into the stage of intensive treatment and rehabilitation. The former was categorized into suppression by the disease, repetition and endurance of the painful life, and separation from their family and frustration. The latter was categorized into the rediscovery of self through social role change, others who helped realize the life potential, the expansion of mental health services in the community, obstacle to the integration of communities, re-integration of family relationships, re-analysis of experience of the disease through the examination of the life prior to onslaught of the disease, and expectation for the future. Also, these themes were comparatively examined so as to examine the crisis progress in the mentally ill's life after the onslaught of the disease, as well as the life transfer process through positive rehabilitation. Lastly, on the basis of these results, important areas of mental health services for the mentally ill were discussed.

The purpose of this study was to explore the implications of the integrated support through the 'health - medical - welfare' network and the specific context of the operation through the experiences of the users who participated in the 301 network project of Seoul northern municipal hospital. To do this, In-depth interviews were carried out with 10 research participants. The data was analyzed by general qualitative research methods. As a result of analysis, users lost their willingness because of living in a vicious cycle of poverty and illness before participating in 301 network services, but through the participation of the service, they were able to receive the integrated support of 'cure-care-life stability'. These experiences ultimately led to the regeneration of the will of their lives. At the basis of this experience were operating strategies and conditions such as the formation of a diverse professional team, the establishment of a linkage system within and outside the hospital, the establishment of a treatment linkage system through the acquisition of treatment subsidies, and the linkage of resources at mediation level. As the attempt to integrate 'health, medical and welfare' with well-coordinated strategies and conditions showed the possibility of complementing the limitation of the health welfare support system in Korea, the extension of the related business was suggested. For this, it suggested the more stable stabilization of the linkage system and the improvement of the institutional aspect.

This study was performed to analyze the secondary students' perceptions and self-efficacy of performance assessments in the science subject. The data was obtained from 236 middle school students and 222 high school students in seoul. The students had generally proper understanding about characteristics of performance assessment which include purposes of assessment and differences from other conventional achievement assessments. They responded that the performance assessments were not useful in their science learning and developing their potential abilities. They were not satisfied with reliability and validity of the performance assessments. The middle school students more positively responded than high school students regarding the reliability of the scoring system and the originality of the evaluating materials. The female students more positively thought than males about the reliability of assessment and the usefulness for learning science. The students' self-efficacy level of performance assessment were not low in comparison with another existing assessments. They had high level of self-efficacy in understanding of experimental procedures, and utilizing of experimental apparatuses, but had low level of self-efficacy in understanding purposes of experiments or issues of discussions, processing of experimental results, answering of problems in experimental discussions. The female students' self-efficacy of performance assessment were higher than male students'. There was statistically correlated with females' scores and their level of self-efficacy of performance assessment.

The purpose of this study was to examine the effects of storytelling lessons using picture books on the resilience of adolescents and the parent-child relationships in the family unit of home economics subject in middle school. For this purpose, I selected picture books of five themes on family type, family relationship, family conflict, sexual violence, domestic violence, and family loss, and developed a teaching-learning process plan for 'Family class with picture book' using storytelling elements and techniques. The teaching-learning plan was applied to 194 middle school students in technology·home economics classes, and the learning effet was evaluated by comparing pre- and post-tests. As a result, the resilience level perceived by adolescents increased significantly after class, but no significant effect was found on self-expansion, which is a sub-factor of sociality. In the parent-child relationship of adolescents, the effect of instruction was shown in all areas, and the affectional bonds felt in the relationship with mother than with father showed higher increase. In the family unit of home economics, storytelling lesson through picture book seems to have a positive influence on the adolescents in their relationship with the family by bringing up the potential power in them to stand against the adversities they may face.

Massively Multiplayer Online Role-Playing Games (MMORPGs) are played by millions of people around the world. Within MMORPGs, players explore, solve mysteries, craft items, battle against dungeon or raid bosses, or compete against other players, all while using a variety of information and information behaviors. Role-players in MMORPGs develop identities and engage in interactive storytelling with other role-players as their characters. An ethnographic approach combining overt participant observation and engagement, semi-structured interviews, and artifact collection was used to explore and describe the social information behaviors of role-players through the lens of the theory of information worlds. The social types evident in the role-playing community in WildStar, a science fantasy-themed MMORPG, are closely interrelated to and differentiated by social norms and information values that dictate acceptable characters, stories, character actions, and appropriate lore sources as well as how to role-play without violating the boundary between in- and out-of-character information worlds. Role-players maintained the in-character and out-of-character boundary using a set of specific information behaviors to enable engaging and immersive role-playing experiences. Implications of the findings for the theory of information worlds as well as potential applications of role-playing and MMORPGs are also discussed.

The purpose of this study was to identify the trends and risk of bias of research using time series analysis on health and welfare in Korea and to suggest a direction for future health and welfare research. The database searches identified 6,543 papers. Following the process for screening and selecting, a total of 91 papers were included in the systematic review. There has been a steady increase in the number of articles using time series analysis from 1987 to 2013. Time series analysis was applied in medicine and health science journals. The main goals were explanation and description. Most of the subjects were heath status and utilization of healthcare services. The main model used in the time series analysis was ARIMA followed by time series regression. The data were gathered from various sources, including the national statistical office and government agencies. For assessing risk of bias, some studies were found to have inadequate sample sizes or showed no time series graphs and plots. These findings suggest greater widespread utilization of time series analysis in the field of health and welfare and to use the appropriate analysis methods and statistical procedures to obtain more reliable results to improve the quality of research.
