  • At present, tendency of ERP(Enterprise Resource Planning) enterprises is that many ERP enterprises from abroad are rushing into capture of small and medium enterprises at home actively. SAP Korea and Korean Oracle have already showed their new product targeting domestic market of small or medium standing enterprise, and more, even MS(Micro Soft) also rushes into this market in earnest. The domestic business circle of ERP should prepare countermeasure by raising the perfection of product and having good command of minute marketing strategy to survive from aggressive strategy of SMB market. In addition, about the computerization of main affairs of business, ordering developing process was general that developing staffs analysed the affairs of each department that needed computerization and construct according to the operation process by using different tools, but condition is changing that businesses themselves are purchasing business application package from expert soft program enterprise and construct. Therefore, in this study, I try to grasp the problem of management, and define a new process that can help for more efficient management by making it an object producing and management module of enterprise 'K' that is one of domestic small and medium enterprise and that is operating ERP at present. As well, through the analysis of affair related producing, we are aiming to prepare for establishment of target, its range, and making the standard of result evaluation.

  • 화장품용 방부제인 CPN-Gal은 사람 피부세포에 대하여 보다 안전하다고 알려져있다. 장기간에 걸쳐서 CPN-Gal을 생산하는 공정을 확립하기 위하여, β-gal을 생산하는 재조합 대장균을 alginate bead에 고정화 시켜서, 반복 회분식 반응으로 CPN으로부터 CPN-Gal로의 전환반응(transgalactosylation)을 조사하여 보았다. 이 전환반응은 300 ml flask에서 수행하였으며, 반응액에는 고정화된 대장균, 33.8 mM CPN, 400 g/l lactose가 포함되어있으며, pH와 온도는 7.0과 40℃ 였다. 이 때, galactose 한 분자가 lactose로부터 CPN으로 전달된다. 반복 회분식 전환반응은 4회 연속적으로 192시간 동안 성공적으로 수행이 가능하였고, 이 때, 64%의 전환수율을 보였으며, 이 결과는 선행연구 결과에 비하여 보다 우수한 결과이다. 그런데, 반복 회분식 반응이 진행되면서, 192시간 이후부터는 점진적으로 전환수율의 감소가 관찰되었다. western blotting으로 β-gal의 양을 관찰하여본 결과, β-gal의 양의 감소가 관찰되었으며, alginate beads에서 깨어진 금이 또한 발견되었다. 이러한 bead의 깨어짐 현상과 아울러서 β-gal의 불활성화, 그리고 galactose에 의한 product inhibition 등이 192시간 이후의 전환수율 감소의 원인으로 생각된다. 본 연구의 전환공정은 β-gal의 정제가 필요 없이 진행할 수 있기 때문에, CPN-Gal 합성이 보다 실용적이고, 가격 경쟁력 있게 수행될 수 있을 것으로 생각된다. 그래서, 이러한 전환공정이 CPN-Gal을 상업화하기 위한 공정으로 발전하길 기대하고 있다.

  • This study is about reproduction of Yoseon-Cheobli excavated from Byun-su tomb in earlier Joseon Dynasty. There are three Yoseon-Cheobli in Byun-su tomb. The producing process is made in concrete by suggesting the process of producing clothing. Based on the Annals of the Joseon Dynasty, the most frequently recorded one, was reproduced by dying fabric with safflower and indigo plants. Through the research about their specific size, sewing method and construction, it have been produced in the following. First, the revealing that collar to be half-square and to compose the line in the center of collar. The width of the collar is 11.6 12.1cm. Second, the 21~22 pairs of waist lines that are 13~14cm in width fixed at intervals of 0.3cm. The method of making waist lines is twisting either fabrics or silk threads. Third, fine gathering around the part of the waist of skirt, and the size of fold surface is 0.2cm. Sewing method needs running stitch and backstitch. As the result of producing the cloth, it became to possess more ornamental features after transformation suitable to the new environment while the same remained functional features for everyday life such as a dressing shape, length of the bodice and curvy completion line of a collar strip.

  • Process capability indices are used to determine whether a production process is capable of producing items within a specified tolerance. Using conditional distribution, we study some process capability indices ${\hat{C}}_{Gp}$, ${\hat{C}}_{Gpk}$, ${\hat{C}}_{Gpm}$ under conjugate prior distribution. We consider some process capability indices with Gibbs sampling method. Also, we examine some small sample properties related to these estimaters by some simulations.

  • High frequency electromagnetic(EM) waves are increasingly being applied in industries because of saturationat lower frequency bands as a result of huge demand. However, electromagneticinterference (EMI) has become a serious problem, and as a result, highfrequency EM absorbers are now being extensively studied. Also, recentdevelopments in absorber technology have focused on producing absorbers thatare thin, flexible, and strong. Hence, one-dimension ferrous nano-materials area potential research field, because of their interesting electronic andmagnetic properties. Commercially, EM wave absorbing products are made ofcomposites, which blend the insulating polymer with magnetic fillers. Inparticular, the shape of the magnetic fillers, such flaky, acicular, or fibrousmagnetic metal particles, rather than spherical, is essential for synthesizingthin and lightweight EM wave absorbers with higher permeability. High aspectratio materials exhibit a higher permeability value and therefore betterabsorption of the EM wave, because of electromagnetic anisotropy. Nanowires areusually fabricated by drawing, template synthesis, phase separation, selfassembly, and electrospinning with a thermal treatment and reduction process.Producing nanowires by the electrospinning method involves a conventionalsol-gel process that is simple, unique, and cost-effective. In thispresentation, Magnetic nanowire and dielectric materials coated magneticnanowire with a high aspect ratio were successfully synthesized by theelectrospinning process with heat treatment and reduction. In addition toestimating the EM wave absorption ability of the synthesized magnetic anddielectric materials coated magnetic nanowire with a network analyzer, weinvestigated the possibility of using these nanowires as high-frequency EM waveabsorbers. Furthermore, a wide variety of topics will be discussed such as thetransparent conducting nanowire and semiconducting nanowire/tube with theelectrospinning process.

  • As digital broadcasting process and information compressing technologies developed, digital technologies have been used extensively in many visual media such as movies and TV programs, and it is required to develop a new process for 3 dimensional digital programs. The study attempts to develop a new digital video-producing process through pre-simulation using a digital storytelling method, in order to increase the quality of broadcasting, reducing the producing time and improve efficiency. This system, supposed to be used to produce actual broadcasting, includes all tools needed for broadcasting in the program, so users can select an appropriate set among the pre-made library, which saves time for making sets. Also, it offers a storyboard making function by perfectly representing the functions of a virtual camera, and enables users to make the better storyboard, checking the real time movies. In addition, it recognizes objects though avatars, organizes the appropriate set for these avatars to act, and embodies a variety of avatar movements through which it reaffirms the camera's position and organization, minimizing errors and saving time and budget.

  • L-Proline-producing mutant strains were developed by exposing L-glutamic acid-producing bacteria to N-metyl-N-nitro-nitrosoguanidine and UV irradiation. A L-histidine auxotroph of Corynebacterium acetoacidophilum RYU3161(KCTC 0616BP), which was resistant to sulfaguanidine and proline analogs (DHP, AZC, TAC), was isolated. The activity of the mutant strain's $\gamma$-glutamyl kinase was 45% higher than that of the parent strain. The optimum level of L-histidine for production of L-proline was 0.16 g/l. In a 5-1 jar fermenter, the mutant strain produced L-proline at a high concentration (35 g/l) level within 48 h of cultivation.

  • According to the controllability of pulse times and the amount of jumps in the states at these times in the process of fed-batch culture producing 1,3-propanediol, this paper proposes a terminal optimal control model, whose constraint condition is the nonlinear impulsive delay system. The existence of optimal control is discussed and an optimization algorithm which is applied to each subinternal over one cycle for this optimal control problem is constructed. Finally, the numerical simulations show that the terminal intensity of producing 1,3-propanediol has been increased obviously.
