Through a wide variety of disciplines, practices on data access and re-use have been increased recently. In fact, there has been an emerging phenomenon that researchers tend to use the data sets produced by other researchers and give scholarly credit as citation. With respect to this practice, in 2012, Thomson Reuters launched Data Citation Index (DCI). With the DCI, citation to research data published by researchers are collected and analyzed in a similar way for citation to journal articles. The purpose of this study is to identify the characteristics and intellectual structure of sociology field based on research data, which is one of actively data-citing fields. To accomplish this purpose, two data sets were collected and analyzed. First, from DCI, a total of 8,365 data were collected in the field of sociology. Second, a total of 12,132 data were collected from Web of Science with a topic search with 'Sociology'. As a result of the co-word analysis of author provided-keywords for both data sets, the intellectual structure of research data-based sociology was composed of two areas and 15 clusters and that of article-based sociology was composed with three areas and 17 clusters. More importantly, medical science area was found to be actively studied in research data-based sociology and public health and psychology are identified to be central areas from data citation.

This study examined the characteristics of two keyword types expressing the topics in the intellectual structure analysis based on the co-word analysis, focused on overseas open access field. Specifically, the keyword set extracted from the LISTA database in the field of library and information science was divided into two types (controlled keywords and uncontrolled keywords), and the results of performing intellectual structure analysis based on co-word analysis were compared. As a result, the two keyword types showed significant differences by keyword sets, research maps and influences, and periods. Therefore, in intellectual structure analysis based on co-word analysis, the characteristics of each keyword type should be considered according to the purpose of the study. In other words, it would be more appropriate to use controlled keywords for the purpose of examining the overall research trend in a specific field from the perspective of the entire academic field, and to use uncontrolled keywords for the purpose of identifying detailed trends by research area from the perspective of the specific field. In addition, for a comprehensive intellectual structure analysis that reflects both viewpoints, it can be said that it is most desirable to compare and analyze the results of using controlled keywords and uncontrolled keywords individually.

This study aimed to examine the current state of music therapy for adults with intellectual disabilities (ID) by conducting a survey of music therapists. Completed surveys from 32 certified music therapists were included for analysis. The questionnaire was composed of 38 items that asked about the participants' background, work environment and music therapy implementation experience (including assessment, goal establishment, intervention strategy and difficulties). The results of the study showed that music therapy for adults with ID was practiced in diverse facilities. Enhancing social interaction was the most frequently set goal by music therapists, whereas facilities mostly required the music therapy services for emotional stability. Also, instrument playing was used most among music activities, and musical structure was considered most when choosing music for therapy. Among the influential institutional factors, characteristics of the facility were considered most frequently, and the level of functioning was the most considered in terms of client-related factors. To advance the effective use of music therapy interventions with adults with ID, development of music therapy assessment tools and more active communication with facility staff were also suggested when working with this population.

본 연구에서는 낙동강 수계에서 어류의 수생태 건강성이 악화된 지점, 장기간 수질이 악화되거나 수위가 저하된 지점, 보호종이 지정된 지점을 중심으로 어류 서식지적합도지수(Habitat Suitability index, HSI)를 산정하였다. 현장조사는 하천유량이 감소하는 4월부터 6월 사이 총 4회 실시하였고, 투망과 족대를 이용해 어류 채집하였다. 어류의 서식지 특성 조사를 위해 채집 지점에서 수심, 유속, 하상재료를 조사하고 기록하여 엑셀 자료를 구축하였다. 본 연구에서는 실제 하천 단면의 물리적 특성을 잘 반영할 수 있는 WDFW(Washington Dept. of Fish and Wildlife) 방법을 이용하여 어류 서식처적합도지수를 산정하였다. 낙동강 수계 10개 지점에서 실시한 어류 조사 결과는 전체 9과 35종 2,227개체이다. 낙동강 수계 10개 지점의 대표어종을 선정하기 위해 법정보호종, 유영성종, 고유종, 기타 중요종을 검토한 다음 각 지점별 대표어종, 대리어종, 유사어종 등을 산정하였다. 낙동강 수계 전반에 걸쳐 피라미가 우점종으로 조사되었으며, 낙동강 상류지역에는 모래무지, 하류에는 수수미꾸리와 유사한 종의 출현빈도가 높은 것으로 나타났다. 낙동강 전역에 걸쳐 서식하고 있는 피라미는 가능한 대표어종에서 제외하고, 보호종과 고유종을 중심으로 대표어종을 선정하였다. 그 결과 낙동강 상류 내성천 합류전 지점에서는 피라미, 내성천에서 참마자, 위천에서 참몰개, 갑천에서 돌고기, 황강에서 모래무지, 금호강에서 돌마자, 밀양강에서 쉬리. 남강에서 피라미, 형산강에서 참갈겨니, 태화강에서 피라미로 대표어종을 각각 결정하였다. 다음으로 각 지점별 대표어종에 대한 수심, 유속, 하상재료 조사 자료를 이용해 대표어종에 대한 서식지적합도지수를 산정하였다. 최근 갈수기 유량 감소로 생태계가 위협받는 기간이 증가하고 있다. 하천의 정상적인 생태기능 유지를 위한 최소한의 유량이 필요하고, 이를 확보하기 위한 노력이 요구된다. 어류의 서식지적합도지수를 활용해 갈수기 어류 서식에 필요한 최소한의 유량을 결정하거나, 수생태계 복원을 위한 기초자료로 활용성이 높을 것으로 판단된다.

The field of cadastre and land administration is susceptible to changes in technological development and requires a robust system to respond. In Mongolia, there is a need for a future-oriented and robust cadastral system to cope with these changes. Therefore, this study chose the Land Administration Domain Model (LADM) which is created by the International Organization for Standardization(ISO), and analyzed for its application to the cadastral system of Mongolia. For the application of LADM for Mongolia, we analyzed four packages and each class of LADM based on characteristics of Mongolia's cadastral system and cases of countries applying LADM. As a result of this analysis, we have completed LADM national profiling in Mongolia and proposed the possibility of applying LADM. In the future, based on this research, application of LADM will play an important role in Mongolian cadastral system where the current data model standardization is not established and is useful as a reference model.

Using various types of educational media plays an important role in educating students with disabilities. In recent years, augmented reality has emerged as an important technology that can increase the effectiveness of special education programs. This study developed augmented reality contents focusing on the theme 'Weather and Life' in the 'Na' unit of the Basic Special School Curriculum, and explored the possibility of applying the contents to the science education. The contents design instructions and educational programs for this study were developed based on a focus-group interview conducted with five special school teachers and two developers. To explore the possibility of applying the augmented reality contents, a usability evaluation was conducted with 23 special school teachers and 18 students with intellectual disability. The results showed that the augmented reality contents had a high level of usability as the special school teachers received 4.73 and the students with intellectual disability received 4.75 out of 5. As a result of this study, we can draw a conclusion that there is a high possibility of applying augmented reality contents to science education for students with intellectual disability.

The Purpose of this study is to explore if people with intellectual disabilities can play a role as 'meaningful informants' in research process in Korea, by challenging the existing paradigm which consists of suspicion on the communication ability of people with intellectual disabilities and truthlessness of their statements, which results in ignorance on the covered life of people with intellectual disabilities. In this research, lessons which could learn through reinterpretation of my research experience are as follows. Firstly, the deficits of communication ability can be supplemented with restructuring interview instruments such as research questions, visual aids etc and adopting conversation analysis methods. Secondly, Suspicion on the truthlessness of their statements can be restructured by epistemological and methodological reinterpretation on the representation of social reality. Thirdly, the mechanism of exclusion and oppression according to the ignorance can be substituted by 'uncovering the life of people with intellectual disabilities', which can be basis of reconstructing the contents of programmes in the disability service centers and disability policies in the government. With these research results it could be argued that there needs to include people with intellectual disabilities as meaningful informants in the research projects funded by the government and also to provide people with intellectual disabilities with diverse roles in the research process by virtue of the development of qualitative research methods in the near future.
