With advances of information technology (IT) and the Internet, it became much easier to search and collect information through many different types of web search engine. Such information only restricted to the intelligence services became available to the public, and the increased open source changed the intelligence collection activities of governments. Open Source Intelligence (OSINT) was introduced to organize and analyze the large volumes of information. OSINT is actively used after the 9/11 terrorist attack, and the United States government invest a huge amount of budget to conduct research and develope technology about OSINT. Although many Western countries recognize the importance of OSINT and deal with open source as priority, South Korea has not fully understand the important role of OSINT. Therefore, this study introduces the fundamental principles of OSINT and provides practical examples of OSINT usage. OSINT is an effective source to prevent terrorist attacks as well as a variety of crimes. Extensive discussion and suggestions for future usages are provided.

In this paper, the interaural intensity difference (IID)-based sounr source separation method in closely spaced stereo omnidirectional microphones is proposed. First, in order to improve the channel separability, a minimum variance distortionless response (MVDR) beamformer is employed to increase the intensity difference between stereo channels. After that, IID-based sound source separation method is applied. In order to evaluate the performance of the proposed method, source-to-distortion ratio (SDR), source-to-interference ratio (SIR), and sources-to-artifacts ratio (SAR), which are defined as objective evaluation criteria in stereo audio source separation evaluation campaign (SASSEC), are measured. As a result, it was shown from the objective evaluation that the proposed method outperforms a sound source separation method without applying a beamformer.

In this Paper, we analyzed the relative importance of multiple sources and their effects on innovative activities. Through factor analysis, we found 5 sources of innovative activities; university/laboratory source, within firm source, general information source, vertical/competitive relation source, and horizontal relation source. Through regression analysis, we found that (1) 'within firm source' is the most important source on innovative activities, (2) from inputs' point of view, the more 'vertical/competitive relation source' is, the less innovative activities we, (3) from outputs' point of view, innovations are more activated when 'university/laboratory source' is abundant. but, they are less activated when 'general information source' and 'vertical/competitive relation source' is abundant, and (4) according to firm size and innovation stages(newproduct innovation, upgraded product innovation, and process innovation), the effect of sources on innovative activities is different.

The present study investigated how mothers with infants and toddlers obtain information about parenting and examined the nature of maternal parenting knowledge in order to evaluate the quality of the information. The mothers' age and educational level were included in the analysis as a influential factor on parenting knowledge. Four hundred and twenty-nine mothers with infants and toddlers completed the questionnaires issued regarding the source and content of parenting information and parenting knowledge. The results indicated that the mothers with only one child preferred to utilize their friends and relatives as their primary source of information and the mothers with more than one child acquired parenting information from their own previous experience. Second, the subjects were most interested in acquiring information related to physical development and medical problems. Third, the main effects of all independent variables were found. In addition, the interactional effects between the educational level and source of parenting information for the mother with only one child and the interactional effects between age and source of parenting information for the mother with more than one child were determined as a result of this study. These results indicate that there are some high-risk groups when it comes to the acquisition of parenting knowledge and we suggest providing valid and reliable information to these most vulnerable groups.

최근 센서 네트워크 분야를 비롯해 네트워크 분야에서 내용 보호, 인증뿐만 아니라 Source의 위치 프라이비시와 관련하여 많은 연구가 이루어지고 있다. 특히 센서 네트워크에서의 Source 위치는 실제 센서의 지리적 위치이기 때문에 Source의 위치를 노출하지 않는 것이 매우 중요하다. 그리고 인터넷과 Ad-Hoc 네트워크에서 익명성(Anonymity)을 제공하기 위한 기법들이 많이 제안되었지만, 이러한 기법들은 센서 네트워크에 적합하지 않기 때문에 센서 네트워크의 특성에 맞는 익명성 제공 요법이 요구되고 있다. 본 논문에서는 Source의 익명성과 관련해 센서네트워크에서 나타날 수 있는 Eavesdropper의 유형을 정의하고, 이러한 Eavesdropper의 유형에 따라 Source의 익명성을 제공할 수 있는 방법을 제안하였다. 그리고 제안한 방법이 얼마만큼의 익명성을 제공하는가를 정량화하기 위해 엔트로피(Entropy) 성질을 이용해 수학적으로 분석하였다. 그 결과, 제안하는 방법이 보다 높은 익명성을 제공하고, 센서의 전송 거리가 Source의 익명성 제공에 있어 매우 중요한 요소임을 확인하였다.

The purpose of this study was to explore differences in style preference, information source, and store selection behaviors of Korean and Chinese wedding dress shoppers. Data obtained from 141 Chinese and 143 Korean females were analyzed through descriptive analysis, t-test, cross-tabulation and factor analysis. Results for Chinese and Korean consumers depended on the marketer-driven information source as well as on the consumer-driven information source. Both groups considered the aesthetics of the wedding dress as the most important criterion for store selection. There were some differences between Chinese and Korean consumers in style preferences and store selection criteria. Chinese consumers liked a wider range of wedding dress styles compared to Korean consumers. Also, Chinese consumers regarded fashionability as more significant whereas Koreans considered economic benefits more importantly when selecting stores for a wedding dress.

In this paper, we describe a new method for selecting information sources in a distributed environment. Recently, there has been much research on distributed information retrieval, that is information retrieval (IR) based on a multi-database model in which the existence of multiple sources is modeled explicitly. In distributed IR, a method is needed that would enable selecting appropriate sources for users\` queries. Most existing methods use statistical data such as document frequency. These methods may select inappropriate ate sources if a query contains polysemous words. In this paper, we describe an information-source selection method using two types of thesaurus. One is a thesaurus automatically constructed from documents in a source. The other is a hand-crafted general-purpose thesaurus(e.g. WordNet). Terms used in documents in a source differ from one another and the meanings of a term differ depending on th situation in which the term is used. The difference is a characteristic of the source. In our method, the meanings of a term are distinguished between by the relationship between the term and other terms, and the relationship appear in the co-occurrence-based thesaurus. In this paper, we describe an algorithm for evaluating a usefulness of a source for a query based on a thesaurus. For a practical application of our method, we have developed Papits, a multi-agent-based in formation sharing system. An experiment of selection shows that our method is effective for selecting appropriate sources.
