멀티미디어는 다양한 형태로 실세계에 존재하게 된다. 그리고 인터넷과 멀티미디어는 불가분의 관계에 있으며 인터넷 자체가 거대한 멀티미디어라고 간주할 수도 있다. 멀티미디어는 어떠한 기준을 설정하느냐에 따라 다양한 분류가 가능하다. 본 논문에서는 멀티미디어가 어디에 저장되어 어떤 형태로 제공되느냐에 따라 프리젠테이션(presentation), 웹 사이트, CD-ROM 타이틀, 가상현실 시스템으로 분류하고 각각에 대해 중요점들을 설명하였다. Multimedia exists in various forms in this real world. And Internet is inseparable from multimedia. Moreover, we can consider Internet itself as an enormous multimedia. Multimedia can be variously classified according to how to establish the criteria for classification. This paper classified multimedia into presentation. web site, CD-ROM titles, virtual reality system by where the multimedia is stored and the form it is supplied. I explained important matters for each.

Taking the image schema of journey and extending the schema across cognitive domains by means of metaphors and metonymies, we proceed to identify and classify possible role archetypes. Hence, we construct a hierarchy of the established role archetypes in consideration for their topology in the cognitive domains. Finally, we show that our approach and its resultant role archetype hierarchy are effective in NLP.

In the near future, the winner of internet business will be determined by a database marketing technique. Therefore, this paper explains the concept and importance of database marketing on internet. Next, I suggest the method to apply database marketing to internet business. In the construction of internet shopping mall, also, it is important to understand the characteristics of each customer. Personalized information, services, and commodities should be offered according to the needs of each customer. In the end, good database marketing can maximize each customer's satisfaction.

When we use a machine learning mechanism for natural language processing, unsupervised methods are confronted with data sparseness and supervised methods have difficulties in constructing sufficient training data. These problems come from the fact that we do not have sufficient training resources necessary to training. After discussing such problems specifically, we suggest a method to construct extensive training resources, not in an academic view of natural language processing, but in a practical one.
Asymmetry of Magnetic Helicity Flux in Emerging Bipolar Active Regions
Dan Yang,Yunchun Jiang,Jiayan Yang,Yi Bi,Bo Yang 한국천문학회 2014 Journal of The Korean Astronomical Society Vol.47 No.3
We apply differential affine velocity estimator (DAVE) to the Solar Dynamics Observatory (SDO)/Helioseismic and Magnetic Imager (HMI) 12-min line-of-sight magnetograms, and separately calculate the injected magnetic helicity for the leading and the following polarities of nine emerging bipolar active regions (ARs). Comparing magnetic helicity flux of the leading polarity with the following polarity, we find that six ARs studied in this paper have the following polarity that injected more magnetic helicity flux than that of the leading polarity. We also measure the mean area of each polarity in all the nine ARs, and find that the compact polarity tend to possess more magnetic helicity flux than the fragmented one. Our results confirm the previous studies on asymmetry of magnetic helicity that emerging bipolar ARs have a polarity preference in injecting magnetic helicity. Based on the changes of unsigned magnetic flux, we divide the emergence process into two evolutionary stages: (1) an increasing stage before the peak flux and (2) a constant or decreasing stage after the peak flux. Obvious changes on magnetic helicity flux can be seen during transition from one stage to another. Seven ARs have one or both polarity that changed the sign of magnetic helicity flux. Additionally, the prevailing polarity of the two ARs, which injects more magnetic helicity, changes form the following polarity to the leading one.
LINEAR WEINGARTEN SPACELIKE HYPERSURFACES IN LOCALLY SYMMETRIC LORENTZ SPACE
Dan Yang 대한수학회 2012 대한수학회보 Vol.49 No.2
Let M be a linear Weingarten spacelike hypersurface in a locally symmetric Lorentz space with R = aH + b, where R and H are the normalized scalar curvature and the mean curvature, respectively. In this paper, we give some conditions for the complete hypersurface M to be totally umbilical.
Cutaneous metastasis: a rare phenomenon of colorectal cancer
Dan Yang Wang,Feng Ye,Jian Jiang Lin,Xiao Xu 대한외과학회 2017 Annals of Surgical Treatment and Research(ASRT) Vol.93 No.5
Cutaneous metastases from colorectal cancer are extremely rare and generally appear several years after diagnosis or resection of the primary tumor. Although this phenomenon is uncommon, it is very important and often indicates a poor prognosis. We present a case of a 76-year-old female patient with multiple cutaneous metastatic nodules on the back, just 1 month after resection of rectal cancer. Unfortunately, the patient gave up the follow-up treatment due to her age and poor physical condition; she died 3 months later. In view of its rarity of occurrence and lack of experience in treatment, we reviewed the literature and report as follows.

여행에 대한 이미지 스키마를 취하여, 은유와 환유에 의해 인지 영역을 가로질러 스키마를 확장함으로써, 역할 원형을 식별하고 분류해 나간다. 그런 후에 인지 영역상에 각 역할 원형들의 위상을 고려하여, 설정된 역할 원형들의 계층구조를 생성시킨다. 마지막으로 본 논문에서 제시된 접근방법과 그 결과로 생성된 역할 원형의 계층구조가 자연어처리에 효율적임을 보인다. Taking the image schema of a journey and extending the schema across cognitive domains by means of metaphors and metonymies, we proceed to identify and classify possible role archetypes. Hence, we construct a hierarchy of the established role archetypes in consideration for their topology in the cognitive domains.
