This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

포스트디지털 퍼포먼스의 미학 -<천사: 유보된 제목>과 혼합 현실(Mixed Reality)의 비전

주현식 ( Ju Hyun-shik ) 한국드라마학회 2018 드라마연구 Vol.0 No.55

우리는 디지털이 점점 인간화되고 있는 시대, 디지털 혁명 ‘이후’ 디지털 기기가 이미 삶의 전제조건이 된 포스트디지털(Postdigital) 시대에 살고 있다. 디지털적 현실과 아날로그적 현실, 인간과 기계의 혼종화(Hybridzation)에 응답하고 관여하며 비판을 던질 수 있는 퍼포먼스에 대한 논의가 본격적으로 이루어져야 할 시점이다. 2017년에 공연된 서현석 연출의 <천사: 유보된 제목>은 아날로그적 물리적 장소와 가상적 디지털 미디어의 혼재화 과정, 포스트디지털의 혼합 현실의 측면에서 탐색될 수 있는 잠재력을 지닌다. 공연에서 남산 드라마센터라는 실제적 공간은 실제적 공간으로서 현존할 뿐만 아니라 그 실제적 공간에 부재하는 다양한 장소들의 흔적들이 디지털 미디어와 실제 공간의 상호영향에 따라 남산 드라마센터라는 공간에 덧입혀진다. 남산 드라마센터의 실제적 공간은 공연에서 물리적 장소의 다양한 포지션이변형되고 소멸되는 과정을 전시하는 바, 다층화된다. 디지털 테크놀로지와 관객의 몸, 드라마센터의 물리적 공간에 대한 지각이 서로 영향력을 미치는 가운데 실제 공간적 맥락이 순간적으로 사라지고 간헐적으로 새롭게 출현하는 과정이 제시된다. 그럼으로써 드라마센터라는 장소는 실제 극장공간으로서의 장소성을 넘어 지도를 투명한 종이 밑에 받쳐 놓고 베끼듯 다른 장소성들을 투사한다. 실제적, 물리적 몸과 가상적, 디지털적 이미지의 혼합 양상은 공연의 마지막 부분 「옥상의 방」에서 노파의 가상적 이미지가 관객의 실제적 몸에 다가와 ‘갑작스럽게’ 합쳐지는 장면에 의해 절정을 이룬다. 여기서 가상적 이미지와 실제적 몸 사이의 상호행위가 발생한다. 이미지는 몸이 되고, 몸은 이미지가 된다. 관객의 실제적 몸이 노파의 가상적 이미지와 융합되어 관객의 몸은 ‘가상적 몸-이미지(Virtual Body-Image)’가 된다. 이러한 결말은 부재, 가상 이미지, 그리고 디지털 기계 자체가 인간 몸의 현존에 대한 과거의 흔적을 환기하며 미래의 어느 시점에서는 그러한 현존과 관련된 생물학적 경험을 보다 심화시키고 증폭시키리라는 기대를 선사한다. 나에게 부재하는 타자적인 것이 그처럼 뜻하지 않게 나에게 다가올 때, 부재하는 것의 갑작스런 현존은 놀라운 선물(gift), 천사의 의미로서 관객에게 다가온다. 관객이 천사를 맞는 순간은 포스트디지털관점 상 아날로그와 디지털 세계 사이에서 인간이면서 기계가 되고, 실제에 속하는 동시에 가상에서 활동하며, 배우이자 관객이 되는, 새로운 종류의 관객의 탄생, 가상적 관객의 탄생을 예고하고 있다. We live in the postdigital era when digital technologies are humanized and pre-mediated in our lives. Thus, it is time that we should start to discuss on the performance that can responds to the hybridzation of digital and analog, humans and machines. < An Angel: the Reserved Title > directed by Seo Hyun-suk in 2017 has a potentiality that the aesthetics of postdigital performance could be examined because of its mixed reality generated from the dialogue between physical reality and digital devices. In the performance, the Namsan Drama Centre is not only present as a real place, but also overlapped with the diverse traces of absent places by the interaction of real place and digital technologies. In other words, the real Namsan Drama Centre has multi-layers where various positions of the place could be transformed and deteriorated, resulted from the mutual influences among digital technologies, audiences’ bodies, and the physical environment. Hence, the Centre traces different virtual places within the real place. This hybridzation has a peak point in the last rooftop scene where the virtual image of an old lady suddenly approaches and ultimately touches an audience’s body. Here, the interaction between the virtual image and real body happens. The audience’s body becomes a virtual body-image via the mixing. By encounter with the absence, virtual image, and digital machine, the scene reminds the audiences traces of the past and anticipations of the future in the presence of a human body. To abruptly encounter the other realizes the unexpected presence of having been absent. Therefore, this scene symbolizes something present, that is, a gift for audience, serving as a representation of an angel. When the audience is hospitable to the stranger, it is the time that a human becomes a machine, the real is incorporated into the virtual, and the audience transforms to an actor, that is, the birth of a new audience as a virtual audience is expected.

나현식,차준섭 호남대학교 정보통신연구소 1992 정보통신연구 Vol.1 No.-

본 논문은 지역망용 고속통신망에서 사용되는 FDDI 와 DQDB 통신 프로토콜의 구조와 동작특성을 이해하고, 그 성능 특성을 분석하였다. FDDI 와 DQDB는 각각 기본적으로 광섬유 전송매체를 사용하는 이중 토큰링과 이중 버스 토폴로지로서, 지역 통신망에서 100Mbps 정도의 고속전송의 효율성을 지원하고 있다. FDDI 와 DQDB 프로토콜을 사용하는 네트워킹의 성능을 최적화하기 위해서는 네트워크 환경에 따라 성능요인을 동적으로 선택하여야 한다. This paper described the architectural and operational characteristics of the FDDI(Fiber Distributed Data Interface) and DQDB(Distributed Queue Dual Bus) communication protocol for local network. And the performance characteristics of FDDI and DQDB networking is analyzed. The FDDI protocol accepted basically the dual token-ring topology with the optical transmission media. And the topology of the DQDB protocol is the dual-bus. Both FDDI and DQDB support the efficiency of high-speed transmission with 100Mbps on local network. In order to optimize the performance of the networking using the FDDI and DQDB protocols, the performance factors must be selected dynamically in consideration of the environment of network.

羅泫植 호남대학교 1992 호남대학교 학술논문집 Vol.13 No.-

This paper described the architectural and operational characteristics of the FDDI(Fiber Distributed Data Interface) communication protocol. And the performance characteristics of FDDI networking is analyzed. The FDDI protocol accepted basically the dual token-ring topology with the optical transmission media. As the FDDI networking uses the TTR(Timed Token Rotation) access method, so it maximized the efficiency of high-speed transmission with 100 Mbps, and enhanced the throughput and real-time characteristics of frame on networking. In order to optimize the performance of the networking using the FDDI protocol, the value of TTRT(Targer Token Rotation Time) which is the core factor of TTR access method must be assigned dynamically in consideration of the constuctual status of computing resources and the factors of networking characteristics.

This research was carried out to develop methods to remove cholesterols from egg yolk. Efficient removal of cholesterols by corn oil extraction was achieved by mixing egg yolk with corn oil(1:4v/v, at 5,000 rpm for 15 minutes at 50℃. Ninety-four % of cholesterols in egg yolk was removed by repeating corn oil extraction 3 times. When n-hexane was used as a solvent for extraction of cholesterols from egg yolk, best results were obtained by mixing egg yolk with n-hexane(1:4 v/v) at 3,000 rpm for 30 minutes at 30℃. The efficiency of cholesterol extraction was same as corn oil(94% after 4 repeater extraction). The quality of egg yolk after cholesterol removal either by corn oil or n-hexane was not different.

The algorithms in the neural network models are simple inner and outer product solutions, not complex multiple matrix inversions. The major operations in processing elements are multiplications and additions for the matrix-vector products. Implementing such operations with binary number systems, as those of conventional fixed - and floating-point notations, introduces complex hardware circuits and inefficient time-consuming operations due to the significant unbalance of speeds between multiplications and additions. Instead, RNS is proposed in this thesis for the basic operations of processing elements. Considering the input values of neural networks have small ranges, RNS proves to be a solution for simple high speed implementations for the basic operations. In RNS, inter modular operations are independent, which allows the same speed of operations in the additions and multiplications. The parallelism and the recursive feature of matrix-vector operations in the neural network processing also lead to the design of systolic array architecture. In this thesis, 1-D systolic array architecture is proposed to allow the scalable number of nodes. The possibility of overflows may occur in the case of exceeding number of nodes out of RNS range. This limits the scalability. For designing scalable architectures, the number of moduli must be increased. This may give rise the size of sigmoid function increased and the speed decreased. The recursive application of 1-D systoloic array shows a good solution for such problems. In this paper, RNS based on the systolic architecture is designed for the BP network. A special technic is proposed, which is the ROM look-up table method for the fast computation of sigmoid functions. The ROM table contains 2?? sampled data in the activation field of the sigmoid function. The simulation shows that a small scale of ROM is enough for the implementation of sigmoid function operations, which does not require the complex floating-point arithmetic operations. The simulation shows that with 256 nodes the expected speed is 5.12 micro seconds when 20 nano second speed of ROM is used for the multiplier with accumulator.
