The purposes of this research are to develop Engineering Mathematics materials using the relations between Engineering Mathematics contents and not only pre-study contents but also major contents and to find the effect of the mathematics study which is applying them for students majoring in electronics. To accomplish the goals, I made list of Engineering Mathematics contents which is necessary to study electronics. Based on the list, I researched relations between Engineering Mathematics contents and not only pre-study contents but also major contents. After research, I selected some subjects which are related each other, developed study materials and examined responses to the materials. Then I analysed the effects on study attitude after used developed materials in my class. As a result, the major contents which was described in the introduction of the materials helped students to be motivated to study Engineering Mathematics and Pre-study contents described before Engineering Mathematics contents helped them to concentrate on studying Engineering Mathematics. Also it showed that developed study materials were effective in increasing self-confidence which is one attitude in the subcategories for Mathematics study.

This study was conducted to investigate the association between soy protein intake and bone mineral density (BMD) in women using data from 2008 and 2009 Korea National Health and Nutrition Examination Survey (KNHANES). The study sample comprised 686 Korean women who were within the first 12 years of postmenopause and had no history of hysterectomy. Adjusting for age, weight, height and calcium intake, statistical analysis was performed among women under 4 years postmenopausal and at least 4 years postmenopausal, respectively. Among women under 4 years postmenopausal, there was no significant association between soy protein intake and BMD at lumbar spine or proximal femur. On the other hand, in the later postmenopausal women, there was a reverse correlation between soy protein intake and BMD, especially at the femoral neck and the total hip. However, the correlation disappeared with additional adjustment for total protein intake, Na intake and energy intake. In conclusion, there may be no correlation between soy protein intake and bone density in Korean menopausal women.

Technology innovation is regarded as the quintessential process to acquire a competitive advantage. This is especially true in high-tech industries, and firms that recognize the importance of technological innovation concentrate their capacities on developing new technologies, new products, and new processes. In general, such research requires many resources, but not all technological breakthroughs are followed by positive feedbacks. Consequently, the firms in high-tech industries are compelled to find new directions in acquiring technologies. This study examines the factors that influence technological innovation and empirically tests the effect these factors have on its diffusion. Radicality, discontinuity, and exploitation/exploration were selected as the factors from the previous literature on technological innovation and organizational learning. For the empirical test, patent data from the US semiconductor industry were used to describe innovation activities from various fields. From the result, these three factors (Ed- is this what you mean, i.e., radicality, discontinuity, and exploitation/exploration?)were found to have significant meaning as proxies for the diffusion of technological innovation.

대부분의 화성학 교재의 첫머리에 소개되는 배음은 그것이 가진 음악적 가치를 간과하고 과학적 수치에 근거한 자연적 현상으로 다루어지는 경향이 있다. 따라서 본 논문을 통해 배음이 가진 음악적인 중요성을 메이저 스케일의 Diatonic Chord와 Chord Scale을 중심으로 재조명 하고자 한다.

최근 IT 기술과 녹색성장의 연관성에 대한 연구가 활발하게 이뤄지고 있다. 산업별로 IT 기술이 접목되고 있는 상황을 감안할 때 당연한 현상이다. 그렇다면 여기에서 한발 더 나아가 정보보호는 녹색성장과 어떤 관계이고, 또 어떤 역할을 할 수 있을까. 지난 5월 9일 프레스센터 국제회의장에서 개최된 '인터넷 정보보호 세미나'는 그 해답의 실마리를 제공하고 있다.

인터넷 및 보안기술의 발달과 더불어 정보시스템에 대한 침해사고도 기하급수적으로 늘어나고 있으며, 공격기술 또한 정밀화, 분산화, 대규모화되어 가고 있다. 그러나 현재 광범위하게 사용되고 있는 침입탐지 시스템들은 그러한 인터넷상의 공격들에 대한 적절한 분석이나 효율적인 대응책은 제공해 주지 못하고, 대량의 침입탐지 정보를 생성시켜 관리자의 부담을 가중시킨다. 본 논문에서는 침입탐지 시스템이 생성하는 다수의 침입탐지 정보를 분석하고 가공하여 적시적이고 효율적인 대응에 필요한 고 수준의 정보를 생성해 내고, 나아가서는 DDoS 같은 대규모의 공격까지도 조기에 탐지해 낼 수 있는 능력을 갖춘 침입탐지 정보 연관성 분석 시스템을 제안하고 제안된 시스템의 성능 평가를 실시한다.

Lately, developing systems fully interoperable with others is considered an essential element for successful projects, as not only do e-commerce becomes ubiquitous but also distributed systems' paradigm spreads. However, since definitions of interoperability vary by viewpoints, it is still difficult to have the same understanding and evaluation criteria on interoperability. For instance, various interoperability parties in military use different definitions of interoperability, and its T&E is not conducted according to the definition, but only to levels of information exchange. In this paper, we proposed a new definition of interoperability as followsm First of all, we collected existing and various interoperability definitions, extracting key components in each of them. Second, we statistically analyzed those components and applied the association rules discovery in data mining. We compared existing interoperability definitions to ours. From this research, we found associations among the components from various definitions applying market-basketanalysis, redefining interoperability. Key findings of this research can contribute to a unified viewpoint on the definition, level, and evaluation items of interoperability.

네트워크 보안 상황인지 기술이란 현재 네트워크에서 보안과 관련하여 무슨 일이 발생하고 있는 지를 관리자에게 인지시켜 주는 기술이다. 이는 침입탐지시스템이나 방화벽에서 수행하는 잠재적인 공격자의 패킷을 필터링하거나 보고하는 것과는 달리 현재 네트워크에서 발생하고 있는 상황(침입 또는 공격 등)을 알려주는 것에 초점을 맞춘다. 네트워크 보안 상황인지 기술에는 데이터 선정 및 수집, 특성 인자 추출, 연관성 분석, 데이터마이닝, 패턴분석, 이벤트시각화 등과 같이 매우 다양한 세부 기술들이 있지만, 본 고에서는 이벤트 종류에 따른 시각화 기술들의 현황과 ETRI에서 개발한 Visual Scope에 대해 살펴보고자 한다.

Association rules among product items by association analysis suggest sales effect among products. These are useful for marketing strategies such as cross-selling and product display etc. However, if we evaluate more practical product values reflecting cross-selling effects, they will be also more useful for the decisions of companies such as product item selection for product assortment and profit maximization etc. This study proposes product value evaluation models with the concept of effective value based on single-item association chain and itemset association chain. In addition to that, we performed experiments with transaction data related to clothing of an online shopping mall in Korea to show the performances of our models. In result, we confirmed that some items increased in effective values compared with their pure values while the others decreased in effective values.
