프로토타이핑이란 개발자들과 사용자들의 의사소통상의 효과를 증진시키기 위하여 취하는 시스템개발상의 기법이며, 이러한 프로토타이핑에는 가상 프로토타이핑과 실물 프로토타이핑이 있다. 본 논문에서는 기존의 실물/가상 프로토타이핑 연동 기법을 개선해서 오브젝트 기반의 임베디드 시스템 통합 프로토타이핑 개발 환경을 구축하였다. 이러한 새로운 임베디드 시스템 개발 환경을 구축함으로써, 재사용성, 유연성, 확장성 그리고 편리성을 가질 수 있다.

임베디드 시스템은 안정성이나 신뢰성이 매우 중요하고 개발 난이도가 높음에도 불구하고 상품의 개발기간을 최소화하여 시장진입시점을 빠르게 해야 하는 어려움이 있다. 프로토타이핑 개발 방법론은 그러한 임베디드 시스템 제품의 개발 비용을 최소화하고 경쟁력을 강화하기 위해 널리 이용되고 있다. 본 논문에서는 프로토타이핑 개발도구인 RapidPLUS와 ESPS(Embedded System Prototype Suit)를 이용하여 가상 프로토타이핑을 하여 자동차 시뮬레이터와 실물 프로토타입인 모형자동차를 구현한 후 무선인터넷을 이용한 원격자동차 제어 e-Car시스템을 구현하였다.

Jeungsan, Kang Il-Sun (hereafter, Jeungsan)'s perspective on divine beings can be characterized by the philosophical notion of divinity, which recognizes a variety of divine entities. Jeungsan insisted that all things embrace divine entities. Furthermore, he claimed that the backgrounds of all incidents were influenced by these gods. Jeungsan thought that the universe consists of the heavenly realm, the earthly realm and the underground realm. He insisted that there were many gods in each realm. And Jeungsan defined his times as the era of divine beings, which meant that the age was a time for divine beings to actively interact with one another and take the lead in world affairs. Divine beings were briskly involved in human affairs and could either reciprocate gratitude or attain revenge. They were also divine beings that could change the acts and perception of humans as well as judge human acts. However, Jeungsan predicted that by the time the paradisiacal land of immortals was established in the Later World, divine beings would instead run errands for humans. In addition, he forecast that divine beings would be entities likely to harbor grievances just like humans, yet they would ultimately become perfected beings in the Later World. Jeungsan further suggested a multitude of various concepts such as the mutual relationship wherein the realm of divine beings and the realm of humanity interrelate with each other, the mutual responses and functions between them, mutual itineration, co-existence, and the homogeneity of divine beings and humans, which described how both have the same innate characteristics. Jeungsan proposed the concept that 'Divinity is an existential state experienced after one's death." In this regard, he is the one who formulated a new perspective of divinity. Moreover, Jeunsan stressed the immortality of humans (continuity or eternality) and the co-existence of divine beings and humans. He emphasized that divinity is intrinsically immanent and the realm of divine beings has a hierarchical system that maintains order and is akin to that of the human realm. Jeungsan recognized a revolutionary change and perspective based on humanity by suggesting a unique view of humanity. In other words, he was a religious figure who introduced an ingenious view of divinity and dramatically transformed this pattern of reasoning. In conclusion, Jeungsan re-interpreted traditional views of divinity in Korea and systemized them into a new concept of divinity in an ingenious way.

The process in the formation of primordial germ cells, primitive and early gonadogenesis were investigated by histological examination for the reproductive physiological study in the scorpion fish, Sebastiscus marmoratus. The primordial germ cells about $10\;{\mu}m$ in diameter were observed in the fibrous mesenchymal tissue located between gut and mesonephric duct of the larvae within the maternal body. As the fibrous epithelium extends to the direction of peritoneum, the primordial germ cells moved. From 31 days post parturition, the fibrous epithelium gets thicker, and the primitive gonad starts to form. From 49 days post parturition, as the primitive gonad of the primitive gonad extend, it starts to form cavity, and about 60 days post parturition, the formation of the ovarian cavity is completed. From 79 days post parturition, germ cells proliferated along the inner edge of the ovarian cavity.

Recently increasing usage of smart phones so, the application field of convergence industry between IT technology using smart phone-based mobile communication networks and other industry branches is expanding. In addition, R&D technologies in other fields are applied to smart phone applications effectively in order to develop products and support daily life more convenient. However, it is very hard to control these products and there is no efficient solution for this problem when many people are sent to specific area for big events, such as Biennale, Film Festival, EXPO, and so on. In order to solve this problem, this paper describes a network-based ticket reservation system and its organization using augmented reality on smart phone and mobile communication networks. In particular, we propose a method of designing and developing prototyping system based on smart phone application design technologies, prior to developing real smart phone application.

In the virtual prototyping environment, we can simulate details of a target model using many components and libraries provided in advance on a computer. The real prototyping environment provides the test simulation environment as a real product, but we can't do a detailed simulation of a real product in the virtual prototyping environment, and we can't do various simulations in the real prototyping environment. So, we made a integrated prototyping environment for linkage of the two types of prototyping environments. Also, in this paper, we developed the integrated prototyping environment based on objects. By this kind of embedded system development environment, we can have the advantages as reuse, flexibility, scalability, and more convenient of product making.

This study was focused on improving nitrification efficiencies of M-dephanox (Modified-Dephanox) process. Rotating biological contactor (RBC) was used instead of floating sponge type media in nitrification reactor. High ammonia removal efficiencies were observed in nitrification reactor, regardless of organic loading from contactor of M-dephanox process. Denitrification efficiencies were also increased to maintain low $NO_3-N$ concentration in effluent. This enhanced phosphate release in anaerobic contactor and resulted in high removal efficiencies of phophorus. Average removal efficiencies of $TCOD_{Cr}$ and $SCOD_{Cr}$ were 93.8% and 81.6%, respectively, while those of TKN and ${NH_4}^+-N$ were 80.9% and 74.4%, respectively. As for phosphorous treatment, the average removal efficiencies of TP and OP were 94.7% and 94.3%, respectively. Also, effect of operating temperature on nitrogen removal was examined. Average removal efficiency of TN was 65.8 % at $15^{\circ}C$ or below (at average temperature of $13.3^{\circ}C$), while that was 82.8% at $15^{\circ}C$ or above (at average temperature of $21.9^{\circ}C$).
