This paper compares two recent methods for exploring a scientist's research history: citation identity and self-citation network. The former is proposed by White(2000), while the latter is suggested by Hellsten et al.(2007). An experimental citation analysis was carried out on the research output of Young Mee Chung, a renouned Korean information scientist. The result shows that the two methods divided the research period into two sub-periods in the same way. They also identified the major research themes very similarly. In the analysis of each method's performance in depth, the two methods revealed different functions to understand a researcher's history. Citation identity was useful to identify authors who have affected Chung's research in terms of research topics. whereas, self-citation network was successful to identify the core papers and leading papers of the research sub-periods. This study indicates the combination of two methods can provide rich information on a scientist's research history.

웹 자원의 휘발성에 대한 불안에도 불구하고 학술정보 유통의 거대한 통로로 웹이 부상함에 따라 웹상에 존재하는 정보자원들이 학술정보의 재생산에 활용되어 왔다. 이에 본 연구는 학술정보에 인용된 웹 자원의 현황을 살펴보고 그것의 접근성과 유용성이 어느 정도 보장되는지를 살펴보기 위해 문헌정보학 분야의 대표적인 학술지 중 하나인 한국문헌정보학회지를 대상으로, 2007년에서 2011년까지 5년간 수록된 논문에 인용된 웹 자원을 조사.분석하였다. 본 연구를 위해 수록된 논문들의 참고문헌 중 웹 자원 비율, 현시점에서의 웹 자원의 접근 가능성, 그리고 웹 자원 주소를 분석하여 도메인과 파일 각각의 비율과 종류에 대해서 조사하였다. 또한 표기된 웹 자원의 주소는 아니더라도 인용에서 사용한 정보를 통해 웹상에서 여전히 사용가능한지를 살펴보기 위해 세계 3대 검색엔진을 사용하였다.

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.

The purpose of this study is to investigate the cultural difference between eastern and western culture in the online community in view of Hofstede dimensions of national culture through social network analysis. And this study tries to interpret the cultural dimensions by using social network indexes. The results show every cultural dimension offered conflicting results except uncertainty avoidance. The eastern culture shows individualism, and low power distance compared to western culture in the online community. Moreover the communication speed of eastern culture is faster than western culture. But eastern culture shows high uncertainty avoidance in the online community similar to an offline culture. This results of this study show that because of certain differences between the offline and online culture, the typical framework we use to analyze offline culture should not be applied to analyze online culture. Therefore we believe that the most important contribution of this study should be related with the finding that we need very different approach to be able to correctly understand the prevalent culture in the online community than the one that we use in the offline community.

In this study, we assessed environmental impacts of compound humidifiers using environmental life cycle assessment and presented the ways to improvements in energy consumption of them. We found eco-design parameters and $CO_2$-eq emissions in each stage of raw material acquisition, manufacturing, transportation, use and disuse in life cycle of the compound humidifiers. The highest $CO_2$ emission is found to be in the stage of use among all stages of life cycle, which is mainly due to power consumption in thermal heating of heating coil for sterilization during humidification. The power consumption and $CO_2$ emission in the stage of use can be reduced to 1/4 and 1/3 at the highest estimate through improvement of sterilization method, respectively. We suggested the replacement of conventional thermal heating coil by ultra violet light-emitting diodes (UV-LED) for sterilization and then presented the experimental results on the sterilization effects of UV-LEDs.

This paper describes a question-answering system that can automatically analyze input texts and questions in Korean natural language. The particular texts used for the research were newspaper articles in the specific domain of sports news. The system consists of a set of Cobol programs and an associated set of data files containing lexicon, case grammar, linguistic rules. and data base. This system employs two retrieval functions of fact retrieval and passage retrieval. Therefore input questions can be answered in forms of either sentence or factual data.

This paper first reviews various techniques proposed for automatic indexing with special emphasis placed on statistical techniques. Frequency-based statistical techniques are categorized into the following three approaches for further investigation on the basis of index term selection criteria: term frequency approach, document frequency approach, and probabilistic approach. In the experimental part of this study, Pao's technique based on the Goffman's transition region formula and Harter's 2-Poisson distribution model with a measure of the potential effectiveness of index term were tested. Experimental document collection consists of 30 agriculture-related documents written in Korean. Pao's technique did not yield good result presumably due to the difference in word usage between Korean and English. However, Harter's model holds some promise for Korean document indexing because the evaluation result from this experiment was similar to that of the Harter's.
