최근 건설경기의 난국 속에서 많은 건설기업들이 경영상의 어려움에 처해 있다. 본 연구에서는 코스피 코스닥 상장 건설기업들을 대상으로 ANP와 DEA 결합 모델을 이용하여 기업의 경영 효율성 분석을 실시한다. DEA 모형에 쓰이는 투입 및 산출 요소의 결정은 ANP 모형의 중요도 분석을 통하여 결정함으로써 기존의 방법보다 효율성 분석 결과의 신뢰도를 제고하였는데, 효율성 분석결과 비효율적 그룹에 대해서는 효율적 그룹으로의 이동을 위한 벤치마킹 대상과 개선을 위한 효율성 수치를 제공한다. 또한 연구의 결과로 나온 기업별 효율성과 주가와의 상관관계를 분석한다. 본 연구에서는 코스피 상장 건설기업 36곳과 코스닥에 상장된 건설기업 21곳인 총57개 기업을 대상으로 기업의 효율성을 평가하였는데, 효율성 분석결과 CCR 효율성이 1인 기업은 4개 기업, BCC 효율성이 1인 기업은 7개 기업, 규모의 효율성이 1인 기업은 4개 기업 이었으며 각각의 효율적 그룹군 기업과 주가와의 상관관계는 CCR, BCC 모형 모두에서 0.7 이상의 강한 양의 상관관계를 나타냈다.

인용 분석은 정보 검색 위주의 단순 학술정보 서비스를 고도화시킬 기회를 제공한다. 그렇지만, 대부분의 연구가 커뮤니티, 연구자, 논문 간 인용 지수 중심의 분석에 초점을 맞추고 있어, 인용 특성파악을 통한 피인용 논문 정보 서비스를 제공하기에는 어려움이 있다. 본 연구는 논문 내 인용 문구분석을 통해 피인용 논문의 인용 특성을 구조적으로 제시할 수 있는, 피인용 논문을 위한 정보 서비스 가능성을 파악하는 것을 목표로 한다. 구글 스칼라를 통해 확보한 인용-피인용 논문 원문들을 대상으로 인용 유형 비율 분석과 인용 확산 분석을 수행하는 방식으로 피인용 논문 특성을 파악하였으며, 정보 서비스에 반영할 수 있는 가능성을 확인하였다.

This study is a descriptive research study to analyze knowledge and attitude about CAM and aromatherapy for health department students in H8 university health department students(528 students) in Chungcheongdo-do. The results of this study showed that the treatment methods and therapeutic advantages of CAM showed a positive attitude and the recognition of the therapeutic effect on aromatherapy was somewhat higher. However, the knowledge level of aromatherapy was rather low. The students of the department of health science showed a relatively high awareness of the need for education in CAM, but aromatherapy showed a relatively low perception. Therefore, in order to reduce patient welfare and symptom in health department, it is necessary to develop knowledge training for knowledge application and effective treatment and development of clinical practice program for various treatment methods.

The purpose of this study was to identify bibliographic characteristics of the top level articles among KCI indexed academic articles. Unlike the existing analysis on citation and most-cited articles, this study analyzed their bibliographic characteristics. The 3,453 articles were collected from 17 social science fields in KCI. The characteristics of authors, institutions, publications, journals, and citations were analyzed. According to the result of the analysis, there was a difference in the ratio of single authors to co-authors and in the number of co-authors. The authors were mostly single authors or two co-authors. In general, the percentage of authors of one article was high. Second, the types of institutions were mostly universities, and there were differences in the number of institutions with authors in each field. And the frequency of the authors' affiliation appeared uneven. There were a number of excellent research institutes and authors depending on the field. Third, the average of years to take to become the top articles for publication was 11 years in 2018. Fourth, most of the published journals were KCI registered journals, and the influence of the journals was not a factor. Fifth, there were differences in the number of cited counts between fields. This study is meaningful to grasp the influencing factors on the bibliographic characteristics of the most-cited articles for the social science field.

The P2P distributed systems are proceeded various studies lively to use the idleness computing resources under the network connected computing environments. It's a general mean to communication from the peer of the shortest downloaded time among same target files to be searched. The P2P search algorithms are very important primary factor to decide a real downloaded time in the criteria to select the peer of a shortest downloaded time. However the peer to give resources could be changed into offline status because the P2P distributed systems have very weakness connection. In these cases. we have a choice to retransmit resources mainly. In this study, we suggested an effective backtracking search algorithm to improve the performance about the request to retransmit the resource.

본 연구는 지리산국립공원 아고산대 훼손지에서 식생복원 효과를 구명하기 위하여 야생풀포기심기, 개량토포설, 환경피해도 요인을 고려하여 입지환경이 다른 2개 대상지에 실험구를 설치한 후 4년(1997년~2000년) 동안 식생피복도와 종다양성을 조사. 분석하였다. 신림지대와 초원지대에서의 복원실험은 야생풀포기이식, 개량토포설, 환경피해도 요인간 상호작용효과는 없었으나, 야생풀포기이식 처리수준간에는 고도의 유의한 차이가 인정되었다. 국립공원 능선부 훼손지의 식생복원 실험 결과 토양이 습한 산림지대에서는 야생풀포기이식 15%피복 처리수준에서 2년안에 식생피복이 이루어졌고, 종다양성은 3년만에 복원되었다. 또한 무처리구에서 3년안에 식생피복이 이루어졌으나, 종다양성은 복원되지 않았다. 바람이 많고, 토양침식이 심한 능선부 초원지대에서는 3년후에 야행풀포기이식과 30% 피복 처리수준에서 식생피복이 양호하게 이루어졌으며, 종다양성은 복원되지 않았다.

Purpose: No attempt has been made to identify the relationship between the study characteristics and citation rates of articles published in the Journal of the Korean Orthopaedic Association (JKOA). This study classified the study characteristics of articles in the JKOA and analyzed the relationship between the study characteristics and citation rates. Materials and Methods: A cohort study was conducted on all articles published from February 2001 to December 2015. Three independent reviewers classified the articles according to the article type, material, time of the study, design, clinical categories, number of authors, and number of cases. The citation numbers of each article by other journals were taken in January 2020. Univariate analyses were conducted to assess the effect of each characteristic, and multivariate linear regression analysis was performed to analyze the overall relationship between the characteristics and the citation rates. Results: A total of 1,640 articles were published from 2001 to 2015, and 724 articles were cited more than once. The articles published in 2009 had the highest average number of citations. Original articles had the highest citation rates, followed in descending order by surgical techniques and reviews, instructional course lectures, and case reports (p<0.001). Among the case reports, articles dealing with general trauma scored significantly higher average citations (mean=1.5, p=0.006). Among the original articles, articles on general orthopedics had the highest citation rates, followed in order by clinical articles and experimental articles. Among the clinical articles, epidemiologic studies (mean=5.0, p<0.001) and studies on the spine (mean=1.7, p<0.001) recorded significantly higher citation rates than the others. Conclusion: Of all the articles published in the JKOA from 2001 to 2015, articles dealing with general trauma had the highest citation rates among case reports. Among the original articles, epidemiologic studies and studies concerning the spine were cited significantly more than others.

The analysis of citing and cited phrases provides an opportunity to enhance search-centric academic information services. However, most current studies focus only on citation analysis among academic associations, researchers, and articles, making it challenging to develop higher citation-based information services. This study proposes citation analysis service methods using citing and cited phrases. First, to verify the feasibility of suggested services, we have collected the most highly cited articles with specific domain terms and followed their citing relationship; after that, we found formal citation types and ratios in the original articles. And we conducted structural analysis, especially with three topics, "Deep Learning," "Green Energy," and "Aging," and then structurally illustrates the citation characteristics of related articles. Finally, we collected four most cited articles and all their citing ones for each subject from Google Scholar and analyzed the ratio of citation types and citation spread. We hope that various citation analysis studies and information services can be further developed based on our discussion for designing better information services.
