In the restoration of endodontically treated teeth, carbon fiber post was recently introduced. The purpose of this in vitro study was to investigate the fracture strength of teeth restored with a pre-fabricated carbon fiber post in comparison with teeth restored with a prefabricated titanium post & custom cast gold post after cyclic loading in the different environment. A total of 30 recently extracted human central incisors of similar dimension with crowns removed were used. All teeth were placed into acrylic blocks and every steps for post and core fabrication were made accord-ing to manufacture's instruction. The post length and core dimensions were standardizd. All teeth were divided into 6 groups: 1) carbon fiber post / atmosphere, 2) titanium post / atmosphere, 3) gold post / atmosphere, 4) carbon fiber post / wet, 5) titanium post / wet, 6) gold post / wet. Carbon fiber post and titanium post were cemented in place using resin cement and cores were fabricated with Ti-Core. Custom cast gold post was made from Duralay pattern resin and cemented using resin cement, too. All specimens were thermocycled 10,000 times. After 50,000 cyclic loading, failure strength was measured using Instron testing machine. Kruskal-Wallis test followed by Mann-Whitney test was used to compare the mean fracture strength. Results were as follows : 1. All specimens showed lower fracture strength in wet environment after cyclic loading than in atmosphere condition, but did not reveal a significant difference. 2. There was no significant difference between carbon fiber post specimen and titanium post specimen in the same environment. 3. Gold cast post specimen showed significant different greater fracture strength than those of others in the same environment. 4. Carbon fiber post specimen showed no root fracture.

We propose an efficient method of de-interlacing in the post-pocessing of HDTV signal. Since the proposed method considers human visual weight, it gives the better performance in the edge information preservation than that of the median filter. The processing time of the proposed method is twice faster than median filter, therefore the proposed method is suitable for the real-time de-interlacing in the post-processing of HDTV signal.

In this paper, we introduce ETRI AI Strategy #1, "Proactively Securing AI Core Technologies." The first goal of this strategy is to innovate artificial intelligence (AI) service technology to overcome the current limitations of AI technologies. Even though we saw a big jump in AI technology development recently due to the rise of deep learning (DL), DL still has technical limitations and problems. This paper introduces the four major parts of the advanced AI technologies that ETRI will secure to overcome the problems of DL and harmonize AI with the human world: post DL technology, human-AI collaboration technology, intelligence for autonomous things, and big data platform technology.

로봇의 영역이 인간의 정신적, 감정적 노동까지 대신하는 지능형 로봇으로 진화하면서 인간과 로봇 관계에서 발생할 수 있는 '로봇윤리'가 중요한 이슈로 떠오르고 있다. 본 연구는 포스트휴먼 시대에 필요한 인간과 로봇의 윤리 성찰을 고찰하고자 하며, 그 중심 내용은 다음과 같다. 첫째, 로봇의 윤리적 실천 가능성에 도전하는 윤리 소프트웨어 개발 사례를 통해 오로지 강제 입력된 윤리 코드만으로 로봇이 과연 옳고 그름을 판단할 수 있는가라는 문제의식에서 출발한다. 둘째, 로봇윤리는 인간의 편향성이 내재된 데이터를 학습했을 때 발생할 수 있는 비윤리적 문제들을 고려하고, 더불어 국가와 문화 간의 윤리적 상대주의를 인정해야 한다. 셋째, 로봇윤리는 로봇을 위한 윤리 강령만이 아니라, 인간과 로봇이 서로 공진화할 수 있는 새로운 개념의 '인간 윤리'가 전제되어야 한다.

최근 4차 산업혁명, 딥 러닝, 인공지능, 포스트휴먼, 트랜스휴먼 등의 용어가 자주 회자되고 있다. 이 용어들은 급격한 과학기술의 발달로 인해 미래는 지금과는 다른 모습이 될 것이라는 것을 짐작하게 한다. 그러나 지금과는 비약적으로 다른 미래 현상에 천착하는 것을 우선시하기 보다는 현재 그러한 미래 기술이나 현상이 어떤 단계에 있는지를 파악하는 것이 먼저가 아닐까 한다. 따라서 본 연구에서는 특히 과학기술을 사람의 몸에 연결 혹은 결합하는 실제 사례들이 늘어나면서 그렇다면 이러한 인간을 무엇이라고 부를 것이며, 어떤 특징을 가지고 있는지를 변화와 변형을 의미하는 트랜스포머티브를 영화 <엘리시움>을 통해서 살펴보고자 한다. 이를 위해 먼저 트랜스, 트랜스포머티브, 트랜스휴먼(니즘)의 의미를 알아보았고, 다음으로 과학기술과 트랜스휴머니즘의 관계를 살펴보았다. 이어서 영화 <엘리시움>에서의 트랜스포머티브 특징 4가지를 분석하고 그것이 트랜스휴머니즘을 이해하는데 어떤 영향을 미치는지를 알아보았다. 이러한 과정은 향후 포스트휴먼과 포스트휴머니즘을 이해하는 단초가 될 것이다.

The importance of communication which is oriented to interaction, fusion and connection is more increased in the post-information society. The information environment is already realized as interface to reach immediately and freely to the databased information and knowledge. The contemporary libraries execute very important roles as an intellectual infra of modern times to deliver the great human achievement and create new culture. In the mean time, the rapid information-oriented society and the development of digital technology bring out big change in the traditional dispatch and receipt method of information. For this reason, libraries as the community space of visitors integrates physical space - electronic space and reconstructs new temporary culture and value to build the new interface that connects human to human, human to space and human to information. On the premise of these awareness, this study analysis the creative interface factor of Tama Art University New Libraries in Ito Toyo in order to research the function and the application method of modern libraries. And the results are follows. 1)We can make sure the significance of communication and the integration consciousness between digital technology and analogue sensitivity that is the characteristic of the post-information society. 2)We can classify for the creative interface factors by the character as space factor(Arcade, Gallery, Lounge, AV Booth, Cafe), facility/equipment factor(Laboratory, Media, Bar, Info Shelf, Media Seat) and furniture factor(Carrel, Desk, Mag Table, XI Shelf). 3)We can see that these interface factors change the stream of library users and that the library is constructed for library users to create and discovery something easily from books and modern technologies. And we can realize also that these factors are creative installation to lead out naturally the latent liberty sense of users.

블록버스터 SF 영화 두 편이 동시에 등장한 2021년은 SF 장르가 열세였던 한국 영화사에 기념비적인 해이다. 넷들릭스에서 제작한 <승리호>와 티빙이 제작한 <서복>이 그 두 편이다. 공교롭게도 이 두 편은 로봇과 복제인간이라는 포스트-휴먼이 등장하는 SF물이다. SF의 시조인 소설 『프랑켄슈타인』에서 알 수 있듯 인간은 오래 동안 인간과 유사한 존재, 혹은 또 다른 인간인 포스트-휴먼에 대해 상상해 왔다. <승리호>는 우주 청소선과 우주 청소부라는 특이한 소재를 다루고 있으며, 인간과 매우 친숙한 로봇이 주요 캐릭터이다. 지구가 황폐화 되어 소수의 인류만이 인공위성으로 이주해 살아간다는 미래 사회를 배경으로 초거대 기업 설립자가 꾸민 음모를 승리호 선원들이 막는 이야기이다. 세련되고 정밀한 CG로 구현된 우주 공간 비주얼이 볼거리이다. <서복>은 시한부 인생을 사는 남성이 실험체로 만들어진 서복이라는 복제인간을 보호하며 동행하는 이야기이다. 두 인물의 실존적 고민을 통해 죽음과 영생이라는 철학적 주제를 다루고 있다. <승리호>는 한국적 신파 정서가 서사에 활용되었고, <서복>은 한국의 지리적공간을 배경으로 한 로드무비 성격을 띠고 있다.

In this study, the effect of augmented reality subtitle content on users was investigated by using a subjective evaluation method and a statistical approach. The human factor was defined as subtitle position and font size. Then, we analyzed the effects of the defined factors on human eye comfort and visibility. Ten participants conducted related survey evaluation tasks with a 1-minute break after viewing the content for 3 minutes.

Vitrification has been suggested to be an effective method for the cryopreservation of human ES cells. However, the efficiency of vitrification with different vehicles remains a matter of ongoing controversy. The objective of this study was to assess the efficiency of cryopreservation in human ES cells by vitrification using different vehicles. A human ES cell line and a variety of vehicles, including micro-droplet (MD), open-pulled straw (OPS) and electron microscopic grid (EM-grid), were employed in an attempt to assess vitrification efficiency. In order to evaluate the survivability and the undifferentiated state of the post-vitrified human ES cells, we conducted alkaline phosphatase staining and characterization via both RT-PCR and immunofluorescence assays. The survival rates of the post-vitrified human ES cells using MD, OPS and EM-grid were determined to be 61.5%, 66.6% and 53.8%, respectively. There also exist significant differences between slow-freezing and vitrification (p<0.01). However, no significant differences were detected between the vehicle types. Finally, the pluripotency of human ES cells after thawing was verified by teratoma formation. Cryopreservation using vitrification is more effective than slow-freezing, and the efficiency of vehicles proved effective with regard to the preservation of human ES cells.
