  • Researches on manipulation pluripotent stem cells derived from blastocysts or promordial germ cells (PGCs) have a great advantages for developing innovative technologies in various fields of life science including medicine, pharmaceutics, and biotechnology. Since the first isolation in the mouse embryos, stem cells or stem cell-like colonies have been continuously established in the mouse of different strains, cattle, pig, rabbit, and human. In the animal species, stem cell biology is important for developing transgenic technology including disease model animal and bioreactor production. ES cell can be isolated from the inner cell mass of blastocysts by either mechanical operation or immunosurgery. So, mass production of blastocyst is a prerequisite factor for successful undertaking ES cell manipulation. In the case of animal ES cell research, various protocol of gamete biotechnology can be applied for improving the efficiency of stem cell research. Somatic cell nuclear transfer technique can be applied to researches on animal ES cells, since it is powerful tool for producing clone embryos containing genes of interest. In this presentation, a brief review was made for explaining how somatic cell nuclear transfer technology could contribute to improving stem cell manipulation technology.

  • 뮤직 비디오는 오디오 음반의 발매와 함께 그에 어울리는 영상을 추가하여 비디오 클립으로 제작되는 멀티미디어유형이다. 원래는 단순한 음반의 홍보수단으로 출발하였으나 음악전문 케이블 M-TV 방영의 주요 콘텐츠로 각광받게 되면서 대량 제작되기 시작하였다. 21세기는 스마트 폰 시대로 애니메이션, 실사 영화, 다큐멘터리를 비롯한 다방면의 영화 제작 기술을 사용하고 있다. 그 중에서 사진적 이미지의 뮤직비디오를 대표하는 사진작가 겸 뮤직비디오 감독인 안톤 코빈과 스테반 세나두이를 중심으로 그들의 작품 경향을 분석하고자 한다.

  • Advertising is a communication that aims to persuade you through communication. Local governments are enforcing a lot of budget for outdoor advertisements and exposing advertisements to various media. However, in the case of outdoor advertisements, advertisements are executed without considering the specificity of the exposure environment, so it is inferior to the budget input. Therefore, this study aims to help local advertisement agents, producers, and related parties by classifying components by combining video analysis methodology and video ad analysis methodology for effective message delivery and immersion in local outdoor advertising. As a discussion to provide an efficient production methodology for outdoor advertising video production in the future, it is an extension of exploratory research through content analysis.

  • For the utilization of animal blood produced in slaughter for the cultivation of lactic acid bacteria, the nitrogen sources in a complex(MRS) medium were replaced by blood plasma proteins. Focusing the purpose on the industrial production of a probiotics, the hydrolytic activities of three industrially applicable proteases were compared for the effective digestion of the proteins, and Alcalase(the product of Novo Nordisk) was selected with comparatively high activity. The growth of Streptococcus thermophilus KCCM12020 was best among the four strains of lactic acid bacteria tested. With Alcalase-digested proteins in the medium, the growth rates and the final cell concentrations were higher than those with non-digested proteins. The cell mass produced in the medium containing blood proteins as nitrogen sources, $2.5{\times}10^9$ CFU/ml, was significantly high and about 70% of that in MRS medium, showing a great possibility for the utilization of animal blood proteins as economic nitrogen sources in the production of cell mass of lactic acid bacteria.

  • Both PM-OLEDs and AM-OLEDs are now in production. However, manufacturers are still concerned about life-time, voltage drift, operating voltage and efficiency in order to develop larger displays. Most material suppliers seem to be focussing on emitters and the benefits of introducing suitable charge transporters have been largely unexplored. OLED-T has developed a novel organic electron injector (Trade Name: EI-101) which evaporates at a very low temperature of $300^{\circ}C$ as opposed to the conventional LiF which requires $580^{\circ}C$. EI-101 has been found to increase the lifetime by up to 12%, reduce the voltage drift by up to 61% and increase the efficiency by up to 15%. The material can be handled in air and in situ Q-mass spectroscopy on extended thermal evaporation has confirmed its high stability for use in mass production.

  • Multiwalled carbon nanotubes were massively produced by the catalytic reaction of C$_2$H$_2$ - Fe(CO)$\sub$5/ mixture at 750 - 950$^{\circ}C$ in a quartz tube reactor and over quartz substrates. Well-aligned MWNT array grows perpendicular to the quartz tube reactor and the quartz substrates at an average of 60 nm in diameter and up to several thousands of micrometers in length. This method does not require any pretreatment of substrates and CNTs are grown at atmospheric pressure. It could be suitable for mass production of multiwalled nanotubes. Scanning electron microscope and transmission electron microscope images of the nanotubes deposited on the substrates allowed us to monitor the quality of MWNTs grown under different operating conditions.

  • The biological control potential of entomopathogenic nematodes (EPN) can be enhanced by improved culture efficiency. Optimization of media is a key factor for improving in vitro mass production of entomopathogenic nematodes. EPN yield was dependant of complex medium concentration, of which mixture is carbohydrates, lipids, proteins, salts, and growth factors, on the growth of Heterorhabditis bacteriophora and its symbiotic bacterium Photorhabdus luminescensLipids.

  • LTPS technology based on SLS Crystallization was intensively reviewed. LTPS structure produced by SLS crystallization is composed of much larger grains compared with conventional ELA crystallization structure, which can give higher TFT performances. However, TFT performance uniformity and anisotropy problem should be solved for it to be used in mass production. TFT performance uniformity was from main grain boundary position and could be solved by equal defect area structure $(EDAS^{TM})$. TFT performance anisotropy could be also solved by multi-channel (MC) structure that can make parallel component in perpendicular channel direction. The higher TFT performances from SLS technology can make superior optical and/or electrical properties and has been adopted in mass production successfully.

  • Injection molding is the one of the most important processes for mass production of plastic parts. Usually Injection molds for mass production are constituted to multi-cavity runner system to manufacture the more parts at a time. To uniformly fill to each cavity, multi-cavity molds are designed to geometrically balanced runner system. However. in practice this is not the case. The previous studies by Beaumount at.[2] reported that filling imbalance occurred by thermal unbalance on the mold and viscosity variation of resins and so on. In this study, we conducted experiments in order to know the causes or filling imbalance for 3 plate type mold with 8 cavities. We presented a new so called 4BF mold(4plate Type Balanced Filling Mold) to improve filling balance. We conducted a experimental injection molding to verify a efficiency of the 4BF mold. In the results of the experiment, We could confirmed the possibility of the 4BF mold.

  • In-process evaluation equipment for the prominent discrete tone (PDT) emitted by small motors or actuators such as HDD(Hard Disk Driver), ODD(Optical Disk Driver) or linear motors has been developed and estimated on the basis of Prominence Ratio (PR) method in ECMA 74. Correlation of the evaluation equipment was performed in comparison with the method by ECMA 74 in anechoic chamber. Coherent function between two systems was applied in order to compensate traceability of ECMA 74 in anechoic chamber. Usability of the developed system with estimated Gage R&R shall be approved with real samples in the mass production line.
