This study analyzes the authorship of all articles published in four domestic LIS journals over a 20-year period from 2002 to 2021 to examine the current status of scholarly communication through Korean LIS journals and suggest future prospects. To achieve this purpose, the study analyzed the number of co-authors, the proportion of returning authors, the publishing preference index (PPI), the author group change trend, and the researcher attraction index (RAI). The analysis revealed the level of collaborative research in each journal, the degree of formation of related author groups by journal, the inflection point of author group changes, the characteristics of emerging researchers, and the degree of author sharing between journals. Overall, 2015 was found to be an inflection point where the author community of Korean LIS journals changed. The newer generation of researchers showed a slightly different behavior of publishing papers than the older generation, as they mainly conduct collaborative research. These quantitative results could be triangulated with the qualitative interview data of previous studies to further strengthen the development strategy of Korean LIS journals.

This study examined two characteristics of library and information science (LIS) journals in Korea through analysis of journal coupling with common authors. This study also illustrated the trend of Korean LIS research in the recent decade. The notable change is that record management and archival studies settle in LIS domain as a major research area. We introduced two indicators, Publishing Preference Index (PPI) and Researcher Attraction Index (RAI), based on the degree of common authors among journals. Both indicators revealed notable changes in author coupling, including reversal of PPIs in some journals, which can be interpreted as proof of changes in their author groups. The RAI analysis, which measured the degree of journals' attractiveness to Korean LIS researchers and author sharing between two journals, illustrated the journals' states in a domain; this result can help find both an isolated journal and strongly bonded journals in the specific domain. Journal coupling with common authors introduced in this study proved to be an effective investigative method for illustrating journals' states in a specified domain as well as a multidisciplinary area.

The purpose of this study is to analyze service quality factors that affect user satisfaction of Open Access Korea(OAK) services and to draw strategic assignments for activating open access activities in Korea through a user satisfaction survey. User satisfaction indexes were developed to measure all aspects of the OAK services. The quality index, satisfaction index, and performance index were identified in this survey. According to the survey findings, the levels of social quality and social satisfaction are relatively high, this shows the positive evaluation and expectation of researchers for OAK services. However, relatively low level is identified in the area of service process quality, and many opinions about OA contents shortage in Korea represent the importance of the national level contents development strategy. Sustainable policy support, publishing of open access journals, management of institutional repository, OA governance system, expansion of researchers' participation, construction of global collaboration system are suggested as major implications to promote open access activities in Korea.

가뭄은 짧게는 한 계절에서 1년, 길게는 10년 이상 지속되는 등 시간 규모가 다양하며, 그 시작과 끝을 명확하게 정의하기 힘든 특성이 있다. 이와 같이 나타나는 가뭄의 장기적 발생 특성으로 인해 지역의 가뭄 특성을 정확하게 분석하기 위해서는 장기간의 자료를 필요로 한다. 그러나 우리나라의 경우 근대적인 관측은 1900년대 초반에 시작되었으며, 현재 운영 중인 대부분의 관측 시설은 1970년대부터 이용 가능한 자료가 존재하는 상황이다. 미국의 경우에도 1800년대 후반부터 관측된 자료를 이용하여 가뭄 및 홍수 분석을 수행하고 있는 실정이다. 이러한 점을 보완하여 보다 장기간의 가뭄 특성 관련 정보를 확보하기 위한 노력이 많은 연구자들을 통해 지속되어 왔다. 강수량이나 유출량 등 근대 관측 이후 이용이 가능한 자료를 통해서도 가뭄과 관련된 유용한 정보를 획득할 수 있으나 보다 장기간의 정보를 확보하기 위해 나이테 등 다양한 기후 지표를 이용한 연구가 수행되고 있다. 특히 과거 가뭄 특성에 대한 복원을 위해 나이테자료를 이용하는 연구는 미국을 중심으로 매우 활발히 이루어지고 있다. 또한 몽골이나 티베트, 중국 등과 같이 근대 기상 관측 자료가 매우 부족한 지역을 대상으로 가뭄 특성을 분석하기 위해 해당 지역에서 확보된 나이테 자료를 이용하는 연구가 매우 활발하다. 그러나 우리나라에서는 나이테자료와 가뭄 특성 간 관계를 검토하고 나이테자료에 근거하여 과거 가뭄 특성을 복원하려는 노력이 거의 전무한 실정이라 할 수 있다. 따라서 본 연구에서는 근대 관측 이전에 대한 가뭄 특성을 복원함에 있어 나이테자료의 활용가능성을 파악하기 위해 가뭄 특성을 나타내는 가뭄지수와 나이테자료의 상관관계를 분석하였다. 이를 위해 우리나라 및 주변 국가에서 확보된 나이테자료를 이용하였으며, PDSI, SPI 등 기존 가뭄지수를 분석에 함께 활용하였다. 본 연구에서 제시된 연구결과는 향후 나이테자료를 기반으로 근대 관측 이전에 대한 가뭄 특성을 복원하는데 있어 유용한 기반 정보로 활용될 수 있을 것으로 판단되며, 나이테자료 등 기후지표를 이용한 가뭄 관련 연구의 기초 정보로 이용될 수 있을 것이다.

An objective expert discrimination scheme is needed for finding researchers who have insight and knowledge about a particular field of research. There are two types of expert discrimination schemes such as a citation graph based method and a formula based method. In this paper, we propose an efficient expert discrimination scheme considering various characteristics that have not been considered in the existing formula based methods. In order to discriminate the expertise of researchers, we present six expertise indices such as quality, productivity, contributiveness, recentness, accuracy, and durability. We also consider the number of social citations to apply the characteristics of academic search sites. Finally, we conduct various experiments to prove the validity and feasibility of the proposed scheme.

Objective : Whether exposure to chronic noise induces an increase in blood pressure, or the development of hypertension, has not been established. A cohort study was performed to identify the effects of chronic noise exposure on blood pressure. Methods : 530 males working at a metal manufacturing factory in Busan, Korea were enrolled for the study. They were monitored for 9 consecutive years, from 1991 to 1999, with an annual health check-up. The subjects were divided into 4 groups, which were determines by noise level categories(NLC) according to noise intensity ; NLC-I: office workers, exposed to noise a level below 60dB(A) ; NLC-II: field technical supporters or supervisors, frequently exposed to workplace noise, wearing no hearing protection device; NLC-III: workers, exposed to workplace noise below 85dB(A), wearing ear plugs or muffs; NLC-IV: workers, exposed to workplace noise over 85 dB(A), wearing both ear plugs and muffs. Results : After controlling possible confoundens, such as baseline age, smoking, alcohol intake, exercise, family history of hypertension, systolic(SBP) of diastolic blood pressure(DBP) and changes in BMI (body mass index), the pooled mean for the systolic blood pressures, over the duration of the study period, were 3.8mmHg, 2.0mmHg and 1.7mmHg higher in NLC-IV, NLC-III NLC-II groups, respectively, than in the NLC-I group. There were no significant differences in the diastolic blood pressures between the groups. Conclusion : This study suggests that chronic noise exposure increases systolic blood pressure independently, among male workers.
