이용재,이영재,Lee, Yong-Jae,Lee, Young-Jae 한국정보통신학회 2010 한국정보통신학회논문지 Vol.14 No.10
3D 스포츠 게임에서 게이머로부터 직접제어를 받지 않고 스스로 동작하는 자율 캐릭터 에이전트들의 역할과 이를 활용한 광고기법에 대해 분석하였다. 이러한 접근은 게임과 광고를 접목한 학제 간 연구로써, 향후 광고가 게임업계의 수익모델로 생산적으로 활용될 수 있음을 의미한다. 분석을 위해 에이전트가 음성과 텍스트로 반응하는 3D 탁구게임과 게임 내 브랜드가 노출되는 간접광고를 직접 제작하였다. 제작 후 에이전트의 역할과 광고의 활용에 대한 게이머들의 태도를 측정하기 위해 설문조사를 실시하였다. 그 결과 유의미한 내용이 발견되었다. 첫째, 3D 탁구게임에서 에이전트의 역할과 표현이 게임에 유용하게 작용한다는 것을 확인 할 수 있었다. 둘째, 게임에 등장하는 광고에 대해 긍정적 태도를 갖고 있다는 것을 발견할 수 있었다. 이는 게임 아이템을 광고적 요소로도 적용할 수도 있다는 가능성을 나탄 낸 것이다. 이러한 결과는, 기능성 게임과 여성향(woman-oriented) 게임에서의 도우미와 파트너 역할 연구를 위한 기초자료로 활용될 수 있다. This research shows how autonomous character agents work in 3D sports game and its application to advertising. It is a kind of interdisciplinary study between game and advertising. In other words, advertising can be used a beneficiary model in game industry. For the purpose of analyzing the role of agents, 3D table-tennis game and advertising tools are developed. The role of agents is booming up and focusing on the game by their voices and texts. In game, several famous brands are showed up as a mean of advertising. This study analyzed the role of agents and advertising from the game user's position. For validity and reliability of the research, questionnaires were analyzed. As a results, several facts are found. Firstly, the agents worked positively as a game boomer. More than half of the respondents answered the agents are useful for the game. Secondly, the advertising tools showed up on the game are helpful to understand the brand. In other words, the game is contributed to build up the brand image. These kinds of attempts may be significant in that the agents are performed as a parter of functional and woman-oriented game. And advertising brands when placed in the game could play the role of the game item or quest. The proposed method can provide the basic references for developing 3D game as an interdisciplinary study.

Many researchers have studied the relationship between the information structure and intonation. Arguments about the relations between the information structure and intonation researched so far can be summarized as follows: the intonation of topic and focus in English information structure is represented as i) a pitch accent, ii) a tune (a pitch accent + an edge tone), or iii) a boundary tone. The purpose of this paper is to study various informational patterns of the topic in English information structure, using real TV discussion data. In this paper, the topic is classified as contrastive topics and non-contrastive topics, based on contrastiveness. The results show that the intonation of the topic in English information structure is implemented as a pitch accent, neither a tune nor a boundary tone. Of the non-contrastive topics, while anaphoric determinative NP topics (Lnc, Lncd) are mainly represented as a H* pitch accent, the pronoun topic(Lp) does not have a pitch accent. Of contrastive topics, while the semantically focused topic(Lci) is mainly represented as a H* pitch accent, the contrastively focused topic(Lcc) is represented as both H* and L+H* pitch accents. It shows that it is not always true that the topic or focus to have the meaning of contrast is represented as a L+H* pitch accent as argued in the previous researches.

현재의 전자빔 묘화의 한계를 극복할 수 있는 마이크로 전자빔 시스템의 전자 광학 렌즈를 제작하였고 전자빔 묘화실험을 통하여 이를 검증하였다. 마이크로머시닝기술을 이용하여 실리콘 전극을 제작하고 이를 양극 접합을 통해 조립하여 다층 전극의 전자 광학 렌즈를 제작하였다. 완성된 전자 광학 소자를 초고진공 챔버에 장착하여, STM(Scanning Tunneling Microscope) 팁에서 방출된 전자빔의 focusing 특성을 관찰하였으며 전자를 집속하여 리소그라피를 수행하였다. E-beam 감광막은 PMMA(Poly-methylmethacrylate)를 사용하였고 0.13㎛의 패턴을 형성시킬 수 있었다. We have fabricated electron-optical lens for micro E-beam system that can overcome the limitation of current E-beam lithography. Our electron-optical lens consists of multiple silicon electrodes which were fabricated by micromachining technology and assembled by anodic bonding. The assembled system was installed in UHV chamber to observe the emission characteristics of focused electrons by the electro-optical lens. We used STM(Scanning Tunneling Microscope) tip for electron source. By performing lithography with the focused electrons with PMMA(poly-methylmethacrylate) as E-beam resist. We could draw 0.13${\mu}{\textrm}{m}$ nano-scale lines.

제올라이트 메소라이트($Na_{5.33}Ca_{5.33}Al_{16}Si_{24}O_{80}{\cdot}21.33H_2O$)에 대한 고압에서의 회절자료가 200 마이크론 크기로 단색화 된 방사광가속기 X-선원과 다이아몬드 앤빌셀을 사용하여 5 GPa까지 측정되었다. 물과 알코올을 사용한 수압 하에서 메소라이트의 초기 탄성 특성은 0.5 GPa에서 1.5 GPa 사이에서 일어나는 ab-평면의 연속적인 팽창과 c-축 상의 수축에 기인한 전체적인 격자부피의 팽창으로 관찰된다. 이후의 압력에서는 회절패턴의 변화로부터 질서-무질서 전이의 증거가 보여진다. 메소라이트의 c-축에 평행한 채널에는 양이온으로서 소디움과 칼슘이 b-축 방향으로 1:2 비율의 질서 있는 배열을 보이고 있는데 이로 인해 1.5 GPa까지 에서는 이러한 배열의 증거인 $3b_{natrolite}$ 격자패턴이 관찰된다. 격자부피의 확장 이후 1.5 GPa 이상에서 2.5 GPa 까지 에서는 격자부피 변화의 정도가 약해지며, 양이온의 무질서적인 배열에 의한 $b_{natrolite}$ 격자패턴이 관찰된다. 이후 압력의 계속된 증가는 점진적인 격자부피의 감소를 유발시키며 새로운 형태의 질서 있는 배열상을 지시하는 $3c_{natrolite}$ 격자패턴으로의 변화를 보여준다. 이로부터 압력에 의한 초수화 상태의 메소라이트는 질서-무질서-질서 형태의 채널 내부 혹은 채널간의 양이온 배열패턴 변화를 겪는 것으로 추정할 수 있다. Powder diffraction patterns of the zeolite mesolite ($Na_{5.33}Ca_{5.33}Al_{16}Si_{24}O_{80}{\cdot}21.33H_2O$), with a natrolite framework topology were measured as a function of pressure up to 5.0 GPa using a diamond-anvil cell and a $200{\mu}m$-focused monochromatic synchrotron X-ray. Under the hydrostatic conditions mediated by pore-penetrating alcohol and water mixture, the elastic behavior of mesolite is characterized by continuous volume expansion between ca. 0.5 and 1.5 GPa, which results from expansion in the ab-plane and contraction along the c-axis. Subsequent to this anomalous behavior, changes in the powder diffraction patterns suggest possible reentrant order-disorder transition. The ordered layers of sodium- and calcium-containing channels in a 1:2 ratio along the b-axis attribute to the $3b_{natrolite}$ cell below 1.5 GPa. When the volume expansion is completed above 1.5 GPa, such characteristic ordering reflections disappear and the $b_{natrolite}$ cell persists with marginal volume contraction up to ca. 2.5 GPa. Further increase in pressure leads to progressive volume contraction and appears to generate another set of superlattice reflections in the $3c_{natrolite}$ cell. This suggests that mesolite in the pressure-induced hydration state experiences order-disorder-order transition involving the motions of sodium and calcium cations either through cross-channel diffusion or within the respective channels.

The purpose of this study is to investigate the potential of a novel tissue engineering approach to regenerate intervertebral disc. In this study, thermosensitive scaffold (chitosan-Pluronic hydrogel) and nanofiber were used to replace the nucleus pulposus (NP) and annulus fibrosus of a degenerated intervertebral disc, leading to an eventual regeneration of the disc using the minimally invasive surgical procedure and organ culture. In preliminary study, disc cells were seeded into the scaffolds and cellular responses were assessed by MTT assay and scanning electron microscopy (SEM). Based on these results, we could know that tissue engineered scaffolds might provide favorable environments for the regeneration of tissues. Organ culture was performed in fresh porcine spinal motion segments with endplates on both sides. These spinal motion segments were classified into three groups: control (Intact), injured NP (Defect), and inserting tissue engineered scaffolds (Insert). The specimens were cultivated for 7 days, subsequently structural stability, cell proliferation and morphological changes were evaluated by the relaxation time, quantity of DNA, GAG and histological examination. In these results, inserting group showed higher relaxation time, reduced decrement of DNA contents, and accumulated GAG amount. Consequently, the tissue engineered scaffolds used in this study seen to be a promising base scaffolds for regenerative intervertebral disc due to its capacity to absorb external dynamic loading and the possible ideal environment provided for disc cell growing.
