The purpose of this study is to investigate effect of axial loads on deep RC beams. Toward this goal, deep RC beams having different shear span-to-depth ratios are fabricated and bending tests are performed on the beams applied with different magnitudes of axial loads. From the tests, strains on various locations, beam deflections, beam compression and shear strains are obtained. The experimental results show that, for the most of the tested beams, failure due to shear is occurred in the axially loaded deep RC beam and the axial load works beneficially to structural performance. However, when the shear span-to-depth ratio is sufficiently small and the large axial load is applied, the beam is failed earlier than as expected due to bearing failure.

We characterized and compared the characteristics of Ca2+ movements through the sarcoplasmic reticulum of inferior oblique muscles in the various conditions including primary inferior oblique overaction (IOOA), secondary IOOA, and controls, so as to further understand the pathogenesis of primary IOOA. Of 15 specimens obtained through inferior oblique myectomy, six were from primary IOOA, 6 from secondary IOOA, and the remaining 3 were controls from enucleated eyes. Ryanodine binding assays were performed, and Ca2+ uptake rates, calsequestrins and SERCA levels were determined. Ryanodine bindings and sarcoplasmic reticulum Ca2+ uptake rates were significantly decreased in primary IOOA (p<0.05). Western blot analysis conducted to quantify calsequestrins and SERCA, found no significant difference between primary IOOA, secondary IOOA, and the controls. Increased intracellular Ca2+ concentration due to reduced sarcoplasmic reticulum Ca2+ uptake may play a role in primary IOOA.

Arguments on Artificial Intelligence and Transhumanism in Ex Machina and Transcendence Artificial intelligence (AI) is intelligence simulated or exhibited by machines such as computers. Transhumanism is “an international and intellectual movement that aims to transform the human condition by developing and making widely available sophisticated technologies to greatly enhance human intellectual, physical, and psychological capacities.” The movies, Ex Machina and Transcendence, have disputable themes about artificial intelligence and transhumanism. Ex Machina is a science-fiction thriller film, that plays on fears of the future, of artificial intelligence, and of the blurred difference between human life and its imitations. It shows how a humanoid robot seizes its power and dominates human world with tragic vision. Transcendence is a film about a scientist's drive for artificial intelligence, and it has dangerous implications when his consciousness is uploaded into a super computer. It especially deals with Kurzweil’s idea of ‘Singularity,’ which is “a future period during which the pace of technological change will be so rapid, its impact so deep, that human life will be irreversibly transformed.” The film not only aims to warn us about the perils of playing God and of technological overreach, but also suggests world-changing possibilities of “technological singularity.” It is hard to say whether such technology would bring utopia or dystopia in the future. There remain, however, many questions to be solved to prove materiality of human mentality, and is still strong faith in immateriality of human soul.

The overall aim of this research was to explore Open-world game through the notion of Paidia and Ludus that proposed by Frasca. As a structured simulation system, the Open World overlap Non-linear events and Linear quests via geographic world. Building own sequence of explore the world with Paidia process, Player collides with the pre-scripted quest. In result of that Meta-Simulator emerge as alternative tool for modeling Meta-Simulation, which presents an alternative, extended use of gameplay. 본 연구는 프라스카가 제시한 파이디아와 루두스의 개념을 통해 오픈 월드의 중첩적 플레이 구성 형식을 고찰한다. 구조화된 시뮬레이션적 체계로 구성된 오픈 월드는, 비선형적 이벤트와 선형적 퀘스트를 통해 광활한 지리적 공간을 중첩적으로 구성한다. 이때 파이디아적 상호작용 과정을 통해 공간을 탐험하며 고유의 시퀀스를 축적한 플레이어는, 완결적 스크립트를 기반하는 루두스적 퀘스트의 결과와 충돌한다. 대안으로 제시된 메타시뮬레이션은 메타 모델의 편집 및 생성 도구로 운용되며, 대안적이고 확장된 의미의 게임 플레이 활용을 제시한다.
국악학 지형의 재검토와 동시대 한국음악학을 향한 사유와 모색

Since the beginning of the 20th century, music of Joseon have been studied by various scholars and writers including Western missionaries, Japanese musicologists and local Korean scholars and musicians with various backgrounds. Even though their studies encompass various areas of study, yet, their studies have remained at the boundary of colonial modernity. After the independence, an institutionalized Korean musicology has established by several individual scholars including Yi Hye-ku, Chang Sa-hun and former musicians of the Yi Wangjik Aakpu, a former court musicians of Joseon. Along with endeavors to establish the rightful history and theory for Korean traditional music after 36 years of colonial period, the field of Korean musicology have developed during last 70 years. However, the aim and purpose of Korean Musicology remained narrow while its perspectives and methodologies were limited, mostly focus on music analysis which resembles the attitude and direction of colonial modernity. To overcome colonial modernity in current Korean musicology, this paper suggests that Korean music should be treated as a process not as a product. At the same time, scholarly perspective of Korean musicology should be broadened including examination of context and culture, away from a simple musical analysis and examination of historical documents and music books. By doing this, Korean musicology would achieve its contemporary meaning in a changing society in Korea and beyond. .
