멀티미디어의 분류에 관한 고찰

양단희 평택대학교 자연과학연구소 2005 자연과학연구 Vol.- No.5

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.

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.

기계학습에 필요한 풍부한 말뭉치의 구축 방안

양단희,이종연 三陟大學校 2000 論文集 Vol.33 No.1

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.

양단희 三陟大學校 2001 論文集 Vol.34 No.1

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.

Fully secure non-monotonic access structure CP-ABE scheme

( Dan Yang ),( Baocangwang ),( Xuehua Ban ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.3

Ciphertext-policy attribute-based encryption (CP-ABE) associates ciphertext with access policies. Only when the user’s attributes satisfy the ciphertext's policy, they can be capable to decrypt the ciphertext. Expressivity and security are the two directions for the research of CP-ABE. Most of the existing schemes only consider monotonic access structures are selectively secure, resulting in lower expressivity and lower security. Therefore, fully secure CP-ABE schemes with non-monotonic access structure are desired. In the existing fully secure non-monotonic access structure CP-ABE schemes, the attributes that are set is bounded and a one-use constraint is required by these projects on attributes, and efficiency will be lost. In this paper, to overcome the flaw referred to above, we propose a new fully secure non-monotonic access structure CP-ABE. Our proposition enforces no constraints on the scale of the attributes that are set and permits attributes' unrestricted utilization. Furthermore, the scheme's public parameters are composed of a constant number of group elements. We further compare the performance of our scheme with former non-monotonic access structure ABE schemes. It is shown that our scheme has relatively lower computation cost and stronger security.

Seismic performance of the concrete-encased CFST column to RC beam joints: Analytical study

Dan-Yang Ma,Lin-Hai Han,Xiao-Ling Zhao,Wei-Biao Yang 국제구조공학회 2020 Steel and Composite Structures, An International J Vol.36 No.5

A finite element analysis (FEA) model is established to investigate the concrete-encased concrete-filled steel tubular (CFST) column to reinforced concrete (RC) beam joints under cyclic loading. The feasibility of the FEA model is verified by a set of test results, consisting of the failure modes, the exposed view of connections, the crack distributions and development, and the hysteretic relationships. The full-range analysis is conducted to investigate the stress and strain development process in the composite joint by using this FEA model. The internal force distributions of different components, as well as the deformation distributions, are analyzed under different failure modes. The proposed connections are investigated under dimensional and material parameters, and the proper constructional details of the connections are recommended. Parameters of the beam-column joints, including material strength, confinement factor, reinforcement ratio, diameter of steel tube to sectional width ratio, beam to column linear bending stiffness ratio and beam shear span ratio are evaluated. Furthermore, the key parameters affecting the failure modes and the corresponding parameters ranges are proposed in this paper.

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.

Argumentness and Probabilistic Case Structures

( Dan Hee Yang ),( Ik Hwan Lee ) 한국언어정보학회 2002 국제 워크샵 Vol.2002 No.-

This paper proposes that the argument structures be stated in a way that uses probabilities derived from a corpus to replace a Boolean-value system of subcategorization. To do this, we make a cognitive model from a situation to an utterance to explain the phenomena of arguments`` ellipsis, though the traditional term ellipsis is not suitable under our new concepts. We claim that the binary distinction is neither rational nor suitable for a real syntactic analysis. To solve this problem, we propose two new concepts argumentness and probabilistic Case structures by adapting the prototype theory. We believe that these concepts are effective in the syntactic analysis of NLP.

Research on the Relationship between Player Type and MMORPG “Grinding” Type

Dan Yang(양단),Dong-Min Cho(조동민) 한국게임학회 2021 한국게임학회 논문지 Vol.21 No.5

MMORPG 중후반에 “Grinding”으로 인해 소모되는 경우시간과 에너지가 갈수록 많아지고, 반복되다 보면 지루한 느낌이 들기 쉽기 때문에 유저의 이탈을 초래하기 쉽다. 본 논문은 MMORPG “Grinding” 8종 유형에 대한 Richard Bartle의 4가지 플레이어 유형의 선호도의 차이를 연구하고자 SPSS 소프트웨어를 사용하여 수집된 200개의 샘플 데이터에 대한 묘사적 분석, 신뢰성 분석, 단요인 방차 분석을 수행했다. 연구 결과에 따라 MMORPG ’Grinding’ 최적화 방안을 게이머 성향 차원에서 제시했다. In the middle and late period of MMORPG, as more and more time and energies are repeatedly consumed due to Grinding, it is easy for the players to feel bored and quit the game. This paper mainly studies the differences in preferences of four types of players for MMORPG grinding types. Apart from that, SPSS software is used to make descriptive analysis, credibility analysis, and one-way analysis of variance on the 200 survey sample data. Based on the content of the experimental results, this study proposes an optimized design plan for MMORPG grinding from the perspective of player tendency.
