In this paper, I will contend that, while the primary role of writing is to convey the information of the spoken words, other kinds and layers of information can also be passed on through the features that writing exhibits. I hope that the ways I examine writing will throw light on the multiplicity of the meanings that writing can create, meanings that have been often overlooked. This paper has looked at multiple additional meanings and usages that writing can have, on top of its primary role as a representation for speech. When words are written down, the definition and meanings can be transplanted as they are, but depending on how the writing is treated physically or visually, there can occur additional connotations that regular speech cannot create. Depending on how writing is presented, it may convey much more messages than speech can normally do. Writing is the transplantation of sound, but the visual features of writing can present significances and meanings in ways that sound cannot. This is the reason why one has to consider the visual elements of the writing.
The Effects of Enjoyment, Reciprocity, and Economic Reward on Helping through Information Systems
Gyudong Lee 한국인터넷전자상거래학회 2016 인터넷전자상거래연구 Vol.16 No.5
In organizations, help-requests frequently occur in the computer-mediated environment such as electronic bulletins and knowledge management systems. The present paper identifies the antecedents of helping in the non-emergency situation. The findings of this study show that enjoyment in helping has a positive effect on willingness to help others in the workplace irrespective of help-provider"s organizational tenure. However, the effects of reciprocity and economic reward on willingness to help others vary according to organizational tenure. Dynamics of these antecedents of helping via information systems are discussed.
Asymmetric Synthesis of (−)-6′-β-Fluoro-aristeromycin via Stereoselective Electrophilic Fluorination
Kim, Gyudong,Yoon, Ji-seong,Jarhad, Dnyandev B.,Shin, Young Sup,Majik, Mahesh S.,Mulamoottil, Varughese A.,Hou, Xiyan,Qu, Shuhao,Park, Jiyong,Baik, Mu-Hyun,Jeong, Lak Shin THE AMERICAN CHEMICAL SOCIETY 2017 ORGANIC LETTERS Vol.19 No.21
<P>(-)-6 '-beta-Fluoro-aristeromycin (2), a potent inhibitor of S-adenosylhomocysteine (AdoHcy) hydrolase, has been synthesized via stereoselective electrophilic fluorination followed by a purine base build-up approach. Interestingly, purine base condensation using a cyclic sulfate resulted in a synthesis of (+)-5 '-beta-fluoro-isoaristeromycin (2a). Computational analysis indicates that the fluorine atom controlled the regioselectivity of the purine base substitution.</P>
동적 물질세계를 위해 전역적 참조 프레임을 사용한 정성적 공간 표현 및 추론법 QSR-14
박규동(Gyudong Park),변영태(Young-tae Byun) 한국인지과학회 2011 인지과학 Vol.22 No.1
사람이 공간에 대한 표현이나 추론을 기술할 때, 정량적 정보 표현과 관련 추론이 어렵거나 불가능 할 때 정성적 표현과 추론을 사용할 수 있다. 2차원 공간에 대한 많이 알려진 정성적 방법 중에 RCC(Region Connection Calculus)-8이 있다. 지역(region)을 공간에 대한 온톨로지 기본 개체로 하는 RCC-8은 위상학적 의미에서 두 개의 지역에 관해 connection 기반의 논리식 및 개념적 이웃과 변환을 나타낸 것으로 각 지역의 이동이나 크기 변화를 전제로 하고 있다. 그러나 현실 세계의 공간 표현과 추론에는 몇 가지 측면들이 더 고려되어야 한다. 본 논문에서는 중력장내에서 일어나는 물리적 화학적 작용에 의해 변화하는 동적인 물질세계의 정성적 공간 표현을 위해 RCC-8의 수정 확장된 방법을 제안한다. 2D의 정성적 공간 표현 및 추론에서 전역적 참조 프레임(global reference frame)의 필요성을 기술하고, 전역적 참조 프레임을 사용하여 동적 물질세계의 물리적 화학적 변화를 표현하고 추론하기 위한 QSR-14을 기술한다. QSR-14는 RCC-8에서 불가능한 상황을 표현할 수 있어 실제 세계의 정성적 공간 표현 및 변화에 더 적합하다고 판단된다. 몇 개의 예제를 통해 정성적 표현과 추론에 대한 QSR-14의 유용성을 보인다. When quantitative representation and reasoning about space is difficult or impossible in a real world, we can use qualitative representation and reasoning. RCC-8 is a well-known qualitative method for 2D space. RCC-8, in which a basic ontological primitive entity for space is a region, shows the connection-based logics and the conceptual neighbors and transitions of topological status between two regions. The transitions happen by changing position or size of regions. However, more aspects have to be considered for representing and reasoning of the world. We propose a modified and extended method QSR-14 for qualitative spatial representation and reasoning of a dynamic physical 2D world in the gravitation field. We mention the need of a global reference frame and describe QSR-14 in detail for representing and reasoning of physical and chemical changes of a real world using the global reference frame. We believe QSR-14 is appropriate for the qualitative spatial representation and reasoning of a dynamic physical world. The usefulness of QSR-14 is shown with several examples.

In this paper, we will compare the general principles of writing development and the six scripts ‘liush? 六書’ of the Chinese writing. The basic presumption in this paper is that although the various writing systems were invented separately, they have gone thorough the same principles throughout the human history. Therefore, it is shown how the principles of the six scripts and the general principles of writing are the same, revealing that the six scripts of the Chinese writing contributed greatly to systematizing the general theory of writing systems. Also, by combining the principles of writing and the principles of the Chinese writing, it can be reconfirmed that eastern writing systems stand side by side in the history of the world"s writing development and there is universal of heritages mankind has been developing for thousands of years. We summarize the main points in the paper as follows. In their early stages, writing systems were made by drawing the shape of objects. This kind of principle was called xiangxing ‘象形, pictograms’ or zh?shi ‘指事, simple ideograms.’ Later on, the hui-yi ‘會意, compound pictorams’ principle was used to make new characters by combining two or more pictograms. It is the principle of economy. Though this principle, the number of writing increased dramatically. In addition, the zhu?nzhu ‘轉注, reciprocal meaning’ principle was a way of adding abstract meanings to characters according to the context. It is the same with the principle of context of situation. By the way of ji?jie ‘假借, phonetic loan’, many homophonous or near-homophonous morphemes were contained in one character. It is the principle of phonetization or the rebus principle. In order to distinguish the characters that have the same sound but different meanings, the xingsh?ng ‘形聲, form-sound compound’ principle was used, which we call the principle of a semantic indicator(or a determinative) and a phonetic indicator.
