In this study, we analyzed the research trend of social network analysis. We investigated how this topic can be linked to the information science. We analyzed 163 articles that were retrieved from searching "social network analysis" in the keyword search field from 2000 to 2009. The study revealed the fast growth of the research of social network analysis in recent years. Also, the study showed that social network analysis has been applied to many cognate disciplines including management science, education science, and administration science. Finally, the study showed that social network analysis is a field equally important to information science as to other disciplines. Particularly, the study demonstrated that social network analysis can be applied to bibliometrics, including webmetrics.

우리나라 전력기술 수준의 평가는 전력기술 중장기 발전계획에 대한 기초자료로서 전력인프라의 투자, 연구개발정책의 수립, 예산배분의 기된 데이터로서 활용되고 있지만, 대부분의 기술수준 평가방법이 전문가 설문조사에 의한 정성적 평가에 그치고 있어 산업 현장의 데이터가 반영되는 데는 미흡한 점이 있었다. 된 논문에서는 이러한 단점을 보완하기 위해 전력기술전반의 수준 평가를 전력산업 각 부분의 계량지표를 관간으로 산출하는 방법에 의한 계량적인 기술평가를 시도하였다. 이 정량적 평가결과를 전문가의 정성적 평가결과 및 과학기술부 조사결과와 대비함으로써 그 차이를 논하고 향후 해석적인 기술평가를 위한 발전방향을 제시하였다.

이 연구에서는 인터넷 자원을 통해 사회과학 분야의 학제성을 측정하고 그 특징을 알아보기 위해 세 가지 계량정보학적 분석을 수행하였다. 먼저 세계적인 사회과학 정보 게이트웨이인 SOSIG의 Grapevine 자료를 통해 사회과학 내 학문분야 간 학제성을 측정하였고, 관련 학자들의 홈페이지 동시링크와 미국 상위 관련 학과 홈페이지의 동시링크를 분석하였다. 그 결과 business, education, philosophy 등을 중심으로 어느 정도 학제성이 나타났으나, 심리학 등 사회과학의 몇몇 분야의 학제성은 예상 외로 높지 않은 것으로 나타났다.

Meter reading system, operated by meter staff who reads the meter and record consumption with handhold data terminals. can cause privacy intrusion, unread meter data, abnormal readings and excessive expenses of maintaining the system. To prevent the deterioration of customer service quality, Automatic Meter Reading system, which automatically recognizes meter readings and transmit reading data through wireless RF module, is designed. From collecting the reading data to managing statistics of customer's consumption information. this automatic meter reading system provides more accurate and fast information to customers. By designing this system, customer service satisfaction and reliability can be improve

Multivariate skew-normal distribution(distribution that includes multivariate normal distribution) has been recently applied to many application areas. We consider saddlepoint approximation for a statistic of linear combination based on a multivariate skew-normal distribution. This approach can be regarded as an extension of Na and Yu (2013) that dealt saddlepoint approximation for the distribution of a skew-normal sample mean for a linear statistic and multivariate version. Simulations results and examples with real data verify the accuracy and applicability of suggested approximations.

As a result of AMI rapidly expanding and distributing its products, variety of services that utilize data on the use of electricity are increasing. In order to make these services more effective, missing metric data needs to be corrected, compensating for which Euclidean similarity is used to find customers with similar usage patterns. Throughout such a process, we propose a method for correcting missing data and provide comparison with the preceding methods.

This study aims to examine Blockchain research trend using bibliometrics-based network analysis. The data were collected from WoS, Scopus, Korea Citation Index and National science & Technology Information Service, from 2009 to 2018. As results, the number of publications has started increasing rapidly from 2017 and it showed the initial stage of formation of coauthor network. Words often used in the title of the publications were related to application development, controversy and technology development. In addition, the majority of domestic papers are in the subject of social science, while international papers tend to focus on engineering issues. The results of the temporal analysis show that Korean researchers' block chain 3.0 started in 2017 and are rapidly increasing in 2018. The number of citations was associated with publication year in a statistically signifiant way. By examining these research trends, we hope that this paper can be a useful basis for the development of blockchain. Future research is expected to reveal more clearly the knowledge structure and characteristics of blockchain around the world.

The rainfall characteristics such as heavy rains are changing differently from the past, and uncertainties are also greatly increasing due to climate change. In addition, urban development and population concentration are aggravating flood damage. Since the causes of urban inundation are generally complex, it is very important to establish an appropriate flood prevention plan. Thus, the government in Korea is establishing standards for disaster prevention performance for each local government. Since the concept of the disaster prevention performance target was first presented in 2010, the setting standards have changed several times, but the overall technology, methodology, and procedures have been maintained. Therefore, in this study, studies and technologies related to urban disaster prevention performance were reviewed using the scientometric analysis method to review them. This analysis is a method of identifying trends in the field and deriving new knowledge and information based on data such as papers and literature. In this study, papers related to the disaster prevention performance of the Web of Science for the last 30 years from 1990 to 2021 were collected. Citespace, scientometric software, was used to identify authors, research institutes, countries, and research trends, including citation analysis. As a result of the analysis, consideration factors such as the the concept of asset evaluation were identified when making decisions related to urban disaster prevention performance. In the future, it is expected that prevention performance standards and procedures can be upgraded if the keywords are specified and the review of each technology is conducted.

This study is to examine academic phenomena of public administration research field in Korea through analysing the trends of researcher behavior. For the purpose of this study I analysed the types of research performance, reference materials, core journals, and the half-life of reference materials by investigating the articles in Korean Public Administration Review which is one of the major journal in this discipline. The results I found out are the followings: most of researches of the public administration are performed individually by the established academic fellows : researchers show their preference to foreign journals: as for the case of domestic journals, researchers tend to refer the latest issue: the major journal is discriminated from the others by getting a higher points
