This study aims to develop a rainfall field tracking method for depth-area-duration (DAD) analysis and assess whether the proposed tracking methods are able to properly estimate the maximum average areal rainfall (MAAR) within the study area during a rainfall period. We proposed three different rainfall field tracking algorithms (Box-tracking, Point-tracking, Advanced point-tracking) and then applied them to the virtual rainfall field with 1hr duration and also compared DAD curves of each method. In addition, we applied the three tracking methods and a traditional GIS-based tool to the typhoon 'Nari' rainfall event of the Yongdam-Dam watershed and then assess applicability of the proposed methods for DAD analysis. The results showed that Box-tracking was much faster than the other two tracking methods in terms of searching for the MAAR but it was impossible to describe rainfall spatial pattern during its tracking processes. On the other hand, both Point-tracking and Advanced point-tracking provided the MAAR by considering the spatial distribution of rainfall fields. In particular, Advanced point-tracking estimated the MAAR more accurately than Point-tracking in the virtual rainfall field, which has two rainfall centers with similar depths. The proposed automatic rainfall field tracking methods can be used as effective tools to analyze DAD relationship and also calculate areal reduction factor.

This study aims at investigating the perceptions of science teachers about the role of visual representations in the teaching of electromagnetism, and finding out how science teachers use visual representations in their teaching of electromagnetism and the difficulties they experience in dealing with those representations. A total of 121 science teachers responded to the online survey. The results showed that most of the teachers agreed to the significance of using visual representations in the classroom but regarded their role as means of simply delivering science knowledge rather than constructing or generating knowledge. For the three visual representations widely used in teaching of electromagnetism in secondary schools (electrostatic induction on electroscope, magnetic field around current carrying wire, structure and principle of electric motor), the teachers preferred teacher-centered use of visual representations rather than student-centered and teacher's construction of representations were the most frequent among four types of use; interpretation, construction, application, and evaluation. The difficulties of teaching with these three visual representations were categorized into several factors; teachers, students, the characteristics of the representations, and lack of resources and classroom environment. Teachers' limited perceptions about the role of visual representations were associated with the ways of using visual representations in their teaching. Implications for the effective use of visual representations for science learning and teaching were discussed.

Purpose: This study was conducted to evaluate the effects of integrated palliative care intervention on quality of life in terminally ill patients. Methods: A comprehensive literature search was performed via PubMed, Cochrane Library CENTRAL, LWW (Ovid), CINAHL and several Korean databases. The main search strategy was to combine terms indicating palliative care intervention, presence of terminal illness and study design. Methodological quality was assessed using Cochrane's Risk of Bias for randomized studies and Risk of Bias Assessment tool for non-randomized studies. Data were analyzed by the Stata 10 program. Results: Eight clinical trials met the inclusion criteria with a total of 356 participants. Integrated palliative care interventions were administered for a mean of 6.5 weeks, 5.6 sessions and an average of 47.8 minutes per session. Effect sizes were heterogeneous, and subgroup analysis was done. Integrated palliative care interventions had a significant effect on quality of life (ES=1.83, P=0.018, $l^2=92%$), spiritual well-being (ES=0.78, P=0.040, $l^2=0$), depression (ES=0.86, P<0.001, $l^2=32$) and anxiety (ES=0.69, P=0.041, $l^2=71.1$). But integrated palliative care interventions had no significant effect on pain (ES=0.365, P=0.230, $l^2=69.8$). Conclusion: Results support findings that integrated palliative care interventions were helpful in lessening depression and anxiety and improving quality of life and spiritual well-being, however, the interventions did not assist pain management in terminal cancer patients. These findings suggest that various integrated palliative care interventions can assist terminal cancer patients with better quality of life in the socio-psycho-spiritual dimension.

This study was designed to examine the diversity census of fungi in rumen microbiome via meta-analysis of fungal 28S rDNA sequences. Both terms, "rumen" and "ruminal," were searched to retrieve the sequences of rumen fungi. As of September 2016, these sequences (n=165) of ruminal origin were retrieved from the Ribosomal Database Project (RDP; http://rdp.cme.msu.edu), an archive of all 28S rDNA sequences and were assigned to the phyla Ascomycota, Neocallimastigomycota, and Basidiomycota, which accounted for 109, 48, and 8 of the 165 sequences, respectively. Ascomycota sequences were assigned to the genera Pseudonectria, Magnaporthe, Alternaria, Cochliobolus, Cladosporium, and Davidiella, including fungal plant pathogens or mycotoxigenic species. Moreover, Basidiomycota sequences were assigned to the genera Thanatephorus and Cryptococcus, including fungal plant pathogens. Furthermore, Neocallimastigomycota sequences were assigned to the genera Cyllamyces, Neocallimastix, Anaeromyces, Caecomyces, Orpinomyces, and Piromyces, which may degrade the major structural carbohydrates of the ingested plant material. This study provided a collective view of the rumen fungal diversity using a meta-analysis of 28S rDNA sequences. The present results will provide a direction for further studies on ruminal fungi and be applicable to the development of new analytic tools.

최근 정보기술의 급속한 발달 따라 사회 전반적인 체제의 정보화 현상으로 개인이나 조직의 활동이 정보와 밀접한 관련성을 가지게 됨으로써 이용자의 정보 수요에 적합한 정보원을 제공하는 매개자의 기능을 수행하고 있는 정보전문가의 역할이 한층 더 부각되고 있다. 이러한 영향이 도서관이나 정보센터의 모든 활동에 파급됨에 따라 정보를 수집, 가공, 분석. 저장 및 전달을 담당하고 있는 정보 전문가는 종래의 문헌중심봉사(book-based service)에서 정보중심봉사(information-based service) 형태로 역할 변환이 요구되고 있다. 특히 주제전문 봉사를 담당하고 있는 사서나 정보전문가는 이러한 정보기술의 파급효과를 더욱 실감하고 있는 실정이다. 이러한 상황에서 본 연구는 첫째, 정보기술의 발달이 사회과학 분야의 정보봉사에 미치는 영향과 효과를 살펴보고. 둘째로 사회과학 분야 정보제공을 위한 정보시스템의 특성 분석과 정보기술을 매체로 이용하고 있는 정보전문가의 정보기술에 대한 인식을 실증적으로 분석하고 있으며, 마지막으로 정보사회에서 다양한 정보제공을 담당할 사회과학 정보전문가의 새로운 역할 모델을 제시하고 있다. 사회과학 분야의 정보제공을 효율적으로 수행하기 위한 정보시스템의 구축은 학제적 성을 지니고 있는 사회과학 전반에 대한 이해와 특성을 파악함으로써 가능하다. 사회과학의 연구대상은 인간 상호작용에 관한 지식의 전반적인 분야를 포괄하고 있어 많은 주제분야가 서로 중복되거나 상호 호환적인 성격을 지니고 있기에. 사회과학 정보시스템이 이용자의 정보요구에 만족을 주기 위해서는 이용자의 유형, 정보요구의 형태 및 그 해결방안에 일차적 관심을 가져야한다. 사회과학 분야의 정보유통 체제를 살펴보면, 대부분 통계자료나 단편적인 데이타로 시작되는 원자료가 사회과학자나 연구자에 의해 "지적 변환(intellectual transformation)" 과정을 거쳐 논문이나 저서 등과 같은 정형화된 문헌의 형태로 나타나게 된다. 정형화된 문헌이 다른 이용자의 요구에 효율적으로 이용되기 위하여 다시 "서지적 변형(bibliographic transformation)" 과정이 수반됨으로써 도서관이나 정보센터의 정보시스템에서 문헌검색이 가능하게 된다. 정보기술의 발달과 보급 이전에는 서지적 변형 단계에서 대부분 정보제공시스템의 역할이 종결되었으나, 최근 정보기술의 활용으로 서지적 변형 후 각종 정보자료의 색인과 초록 및 네트웍 화를 통한 자동화 과정이 이루어짐으로써 이용자의 정보요구에 최대의 만족을 제공할 수 있는 정보자료의 체계적인 분석과 효율적인 통제로 포괄적인 정보관리 차원으로 이전되고 있음을 알 수 있다. 사회과학 분야를 담당하고 있는 사서를 대상으로 실시한 설문조사에서 새로운 정보기술의 활용에 따른 정보전문가의 인지적 혹은 업무 적 변화가 매우 긍정적인 방향으로 뚜렷이 나타나고 있음을 알 수 있다. 정보기술을 이용하고 있는 대부분의 사서들은 정보기술이 그들의 정보봉사 업무를 쉽게, 빠르게. 그리고 정확하게 처리하고 있으며, 새로운 정보기술 습득에 호의적인 반응을 보이고 있다. 아울러 정보기술의 이용에 따른 추가적인 책임이나 의무가 수반되고 있는 것으로 나타나고 있으며, 정보기술이 정보전문가의 역할을 완전히 대체할 정도로 위협을 느끼고 있지는 않는 것으로 조사되고 있다. 종합적인 반응은 대부분의 사서들이 정보 봉사 업무에 정보기술의 활용을 매우 바람직한 것으로 보고 있으며. 이용자 요구를 극대화하기 위한 정보관리에 필수불가결 한 도구로 인식하고 있다. 과거의 유능한 사서나 정보전문가는 자관의 정보원에 대한 철저한 이해로 이용자의 요구에 봉사하는 것으로 간주되었으나, 현재 그리고 미래의 유능한 정보전문가는 자관은 물론 국가적 혹은 세계적인 정보원에 접근할 수 있는 정보원 관리 능력은 물론 정보기술의 활용과 이용자에 대한 교육적 능력을 동시에 지녀야 할 것으로 여겨진다. 이러한 관점에서 사회과학 분야의 정보제공을 담당하고 있는 정보전문가의 새로운 역할을 크게 이용자 보조 역할, 주제전문가 역할. 시스템 전문가 역할, 그리고 정보원 관리자 역할로 구분할 수 있다.

Mobile environments rapidly changing and digital convergence widely employed, mobile devices including smart phones have been playing a critical role that changes users' lifestyle in the areas of entertainments, businesses and information services. The various services using mobile devices are developing to meet the personal needs of users in the mobile environments. Especially, an LBS (Location-Based Service) is combined with other services and contents such as augmented reality, mobile SNS (Social Network Service), games, and searching, which can provide convenient and useful services to mobile users. In this paper, we design and implement the prototype of mobile personal assistant (PA) agents. Our personal assistant agent helps users do some tasks by hiding the complexity of difficult tasks, performing tasks on behalf of the users, and reflecting the preferences of users. To identify user's preferences and provide personalized services, clustering and classification algorithms of data mining are applied. The clusters of the log data using clustering algorithms are made by measuring the dissimilarity between two objects based on usage patterns. The classification algorithms produce user profiles within each cluster, which make it possible for PA agents to provide users with personalized services and contents. In the experiment, we measured the classification accuracy of user model clustered using clustering algorithms. It turned out that the classification accuracy using our method was increased by 17.42%, compared with that using other clustering algorithms.
